Printer works long hours in the environment of the high humility such as kitchen, easily makes its internal parts get rusty Damage, affect service life.The printer of the present embodiment is provided with the box for accommodating desiccant in housing Body, blow vent the most to be opened/closed on box body, described blow vent is configured to during the work of described printer automatic Closing, quitting work is to automatically open up, thus allows printer when quitting work, and is in dehumidification mode, logical The air crossed in desiccant air exercise print casing body dehumidifies, and prevents printer from getting rusty.

With reference to Fig. 4 to Fig. 6, printer is easy at enclosure interior dust stratification after using for a long time, and impact makes electricity consumption The normal work of circuit component, to this end, in another embodiment of the present invention, described printer also includes ash Dirt cleaning system, described printer control circuit includes pcb board 2 and the electricity being arranged on described pcb board 2 Circuit component 19.Dust cleaning system includes the first dust stratification detection device, the second dust stratification detection device and dust Blow device, dust blow device includes being swept into device of air 11, in the present embodiment, is swept into device of air Can be supply fan or inlet air compressor, be swept at the air inlet of device of air 11 and filtration dress is set Put 12, be swept into device of air 11 be arranged at pcb board 2 the cleaning of component 19 installed surface side Pipeline 13 connects, and cleans on pipeline 13 also multiple self adaptation that is arranged at multiple components 19 and goes out QI KOU 14, arranges multi-disc bimetal leaf 15, each self adaptation gas outlet at each self adaptation gas outlet 14 Self adaptation gas outlet 14 is closed by the bimetal leaf 15 at 14 when bimetal leaf 15 is in relatively cold state, Bend to self adaptation gas outlet 14 lateral direction when bimetal leaf 15 is in relatively Warm status, self adaptation is gone out QI KOU 14 is opened, and when the temperature of bimetal leaf 15 is the highest when, self adaptation gas outlet 14 is opened Amplitude the biggest.

First dust stratification detection device includes the first capacitometer for measuring cell fin, element radiating Sheet is made up of multiple fin monomers 16, electric insulation between multiple fin monomers 16, the first capacitance measurement Device is connected with comparator and to comparator feedback actual measurement capacitance, comparator is also connected with memorizer, memorizer Middle Memory Reference capacitance, reference capacitance value is multiple fin monomers when element radiating sheet non-accumulation dust Capacitance between 16, when surveying capacitance beyond the threshold value set so that reference capacitance value is as the criterion, clearly Sweep into device of air 11 to start, through filtered air via the self adaptation gas outlet 14 cleaned on pipeline 13 Blowout, cleans component 19, dirty air through exhaust outlet 20 from actuator housing 11 Interior discharge.

Second dust stratification detection device light-beam generator is arranged on the component on pcb board 2 with at least one The mirror surface 17 of position between 19, it is internal that light-beam generator is arranged on actuator housing 1, and light beam occurs Rectilinear light beam is transmitted into mirror surface 17 with fixing angle by device, after being reflected minute surface 17 reflection, and light beam Be projected onto on the photosensitive switch 18 being provided with within actuator housing 1, when photosensitive switch 18 sense less than During reflection light, automatically start and be swept into device of air 11.

Owing to self adaptation gas outlet 14 being closed when bimetal leaf 15 is in relatively cold state, at bimetal leaf 15 bend to self adaptation gas outlet 14 lateral direction, by 14 dozens, self adaptation gas outlet when being in relatively Warm status Open, and when the temperature of bimetal leaf 15 is the highest when, the amplitude that self adaptation gas outlet 14 is opened is the biggest； So that the area of each self adaptation gas outlet 14 is along with the element below self adaptation gas outlet 14 Temperature is different and different.Because for the element that temperature is the highest, its area of dissipation can be designed to the biggest, or dissipates Heat surface partly is more conducive to the exchange of heat, but the structure being exactly more conducive to heat to exchange also is Air flowing change can be caused more acutely or to make air pass through thinner gap, and this structure is the most favourable In generation and the increase of dust stratification, the dust accumulated after the identical time is the most, just with more cleaning when Many air mass flows are cleared up.

When fin accumulation dust is more when, the gap between fin can reduce, and fin is as one The electric capacity of individual entirety can diminish, so when electric capacity is varied down to certain value when, may mean that dust accumulates Arrive certain stage, so needing to clear up dust.

When pcb board 2 and component 19 dust stratification are more when, the dust stratification on mirror surface 17 is the most more, When dust stratification is more when, dust can produce obvious diffuse-reflectance effect, weakens mirror surface greatly The direct reflection effect of 17, can cause photosensitive switch 18 cannot receive the light intensity of sufficient intensity to be triggered. Also achieve the automatic monitoring for element surface dust stratification degree by another mode, thus significantly change It is apt to that element surface dust stratification is more and the short circuit that causes or heat radiation are smooth and the element burnout problems that causes.

By arranging capacitance detecting and light detection two ways, can backup each other, to guarantee when dust accumulates Can start in time to dust cleaning system when of certain stage, remove the dust that element surface covers.

Particularly, light-beam generator is laser generator 24.

Laser generator 24 directionality is good, and the light after direct reflection will not occur significantly to dissipate, But when some surface attachment after dust, after particularly dust accumulation is more, it will occur significantly Diffuse-reflectance.Thus when having improve dust and free from dust or the when that dust being many and dust is few, photosensitive switch The discrimination of 18 light intensity being able to receive that, improves the reliability for light-intensity test, reduces by mistake The probability started.

Particularly, fin monomer 16 is arranged on an insulating thermal conductor 23, each fin monomer Between 16, the bearing of trend along diffusion sheet is split.

Insulating thermal conductor 23 can be attachment insulating barrier on metal material, is significantly reducing heat conductivility In the case of so that each fin monomer 16 mutually insulated, so that structure between each monomer of fin Become electric capacity.By making each fin split along bearing of trend, permissible between each fin monomer 16 Independent composition electric capacity, it is simple to wiring.

Particularly, the quantity of the bimetal leaf 15 at each self adaptation gas outlet 14 is 6.Double gold Belonging to sheet 15 and include active layers and passive layer, active layers is manganin manganin alloy, and the material of passive layer is mainly nickel Ferroalloy.

When the quantity of bimetal leaf 15 is 6 when, in each bimetal leaf 15, laterally restrict tension force The most less, so that bimetal leaf 15 forms bigger flexural deformation, the quantity of sheet metal foot More than enough, it is not necessary to be further added by the quantity of sheet metal to reduce the reliability of system.

Bimetal leaf 15 uses monel as active layers, and its deformation quantity is relatively big, thus obtains brighter Aobvious opening effect.

Particularly, on the basis of the lower limit of threshold value 0.9 times of capacitance.

On the basis of capacitance when of 0.9 times of capacitance, the dust on electric elements is the most more, as Fruit is cleared up not in time, it will causes element radiating not smooth, thus reduces the serviceability of detection device.

It is as follows that the dust of the present embodiment cleans operating principle:

The when that between component or fin, upper dust stratification being more, the reality between fin monomer away from Defection declines, the air of the non-conductor as electricity between metal fin, also has shared by partial air Space replaced by dust, so the electric capacity between fin monomer can along with the accumulation of dust step by step Decline.When the low lower limit to threshold value of capacitance, start and be swept into device of air.

In addition to this detection mode, it is also provided with the mode of light detection, when dust amasss on mirror surface Tired more when, the reflectance of direct reflection can be reduced, reduce the light that photosensitive switch can receive According to intensity, photosensitive switch sensing is less than reflection light, then photosensitive switch Guan Bi, startup cleans air inlet dress automatically Put.

It is swept into after device of air starts and absorbs the most filtered cleaned air from the external world, send into and clean pipeline In.Shape is altered in steps owing to the bimetal leaf at self adaptation gas outlet is as variations in temperature, so Self adaptation gas outlet now has been opened, and, the self adaptation gas outlet above hotter element is beaten Opening bigger, the self adaptation gas outlet above the most colder element is opened less, so that totally empty The flow of gas can be different according to the different temperatures of element distribution, with improve cleaned air utilization imitate Rate.Can allow be swept into after device of air first blows the very first time and be automatically switched off, the such as very first time can be half point Clock.Then second time that waited allows and is suspended in the ash fall of actuator housing inner space, because while from Adapt to giving vent to anger of gas outlet blown afloat by the dust of component surface, and constantly internal empty to actuator housing Between supplement air, say from main trend, the air being mixed with dust can be discharged from exhaust outlet, but cannot guarantee that After some time, the air being mixed with dust will all be discharged from actuator housing inner space.So After blowing over a period of time, the air in space in drive shell body, is still the sky being mixed with a small amount of dust in fact Gas, so needing to wait for a period of time, allows dust in air settle.Such as second time can be 3 minutes Or 2 minutes.After ash fall in drive shell body, then detect electric capacity, if remaining less than threshold value, So continue to clean, the most repeatedly, so that the dust quilt on element and circuit board Clean up.
