Abstract
A water pump motor is constructed to include a housing, the housing having a conical water guide chamber gradually expanding from the top side toward the bottom side, water inlets around the periphery for guiding water into the water guide chamber, and an air passage for guiding air into the water guide chamber to mix with water, a vane wheel fastened to a motor shaft inside the housing and suspended in the water guide chamber, the vane wheel having triangular vanes radially arranged at the top around the motor shaft, a hollow water outlet pipe holder coupled to the bottom shell to hold a water outlet pipe, the water outlet pipe holder having radial dampers equiangularly spaced around the inside wall to guide water toward the water outlet pipe.
Description
- 1. Field of the Invention
- The present invention relates to a water pump motor for use in an aquarium or the like and, more particularly to such a water pump motor, which has water inlets provided above the water outlet pipe so that water can efficiently pumped to the water outlet pipe, a conical water guide chamber that concentrates intake water, radial dampers that guide water from the conical water guide chamber to the water outlet pipe, and an air passage with an air inlet pipe for guiding outside fresh air into the water guide chamber to mix with water flowing toward the water outlet pipe.
- 2. Description of the Related Art
- FIG. 1 illustrates a water pump motor used in an aquarium according to the prior art. As illustrated, the water pump motor comprises a
housing 2, a downwardly extendedwater inlet pipe 21 provided at the bottom side of thehousing 2, awater outlet pipe 22 transversely provided above thewater inlet pipe 21, awater guide chamber 23 defined inside thehousing 2 in communication between thewater inlet pipe 21 and thewater outlet pipe 22, and avane wheel 24 suspended in thewater guide chamber 23 and connected to the motor shaft (not shown) inside thehousing 2. This design of water pump motor is not efficient in use. Because thewater outlet pipe 22 is disposed above thewater inlet pipe 21, much horsepower is required to pump water from upwards from thewater inlet pipe 21 to thewater outlet pipe 22. Further, this structure of water pump motor has no means to guide outside fresh air into the inside of thehousing 2 for mixing with water passing through thewater guide chamber 23. - The present invention has been accomplished to provide a water pump motor, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, multiple water inlets are provided around the periphery of the housing of water pump motor near the top to guide water downwardly into the inside of the housing in different directions toward a water outlet pipe at the bottom side of the housing. According to another aspect of the present invention, the housing of the water pump motor is provided with an air passage and an air inlet pipe connected with an air hose with an air flow rate regulator for guiding outside fresh air into the inside of the housing to mix with water. According to still another aspect of the present invention, the vane wheel of the water pump motor has triangular vanes radially arranged at the top side around the motor shaft, and the water outlet pipe holder connecting the water outlet pipe to the housing of the water pump motor has radial dampers equiangularly spaced around the inside wall for guiding water from the water inlets toward the water outlet pipe efficiently.
- FIG. 1 is a schematic sectional view of a water pump motor according to the prior art, showing the water flowing direction.
- FIG. 2 is a perspective exploded view of a water pump motor according to the present invention.
- FIG. 3 is another exploded view of the water pump motor according to the present invention.
- FIG. 4 is a schematic sectional view of the present invention, showing the water flowing direction.
- FIG. 5 is an elevational view of the water pump motor according to the present invention.
- Referring to FIGS. 2 and 3, a water pump motor is adapted for use in an aquarium, comprising a housing1, a motor shaft 1A, a
vane wheel 12, a wateroutlet pipe holder 13, alock ring 14, and awater outlet pipe 15. - The housing1 comprises an
air inlet pipe 10, a downwardly extendedbottom shell 11, a conicalwater guide chamber 112 defined within thebottom shell 11, a plurality ofwater inlets 111 through thebottom shell 11 in fluid communication with thewater guide chamber 112 aninside air passage 113 axially provided in thebottom shell 11 in communication between theair inlet pipe 10 and thewater guide chamber 112, and anouter thread 114 extended around the periphery of the bottom end of thebottom shell 11. - The
vane wheel 12 is fastened to the motor shaft 1A provided inside the housing 1, havingtriangular vanes 121 radially arranged at the top side around the motor shaft 1A and a conical bottom recess 122 for easy removal from the injection-molding mold. - The water
outlet pipe holder 13 is a hollow member coupled to the bottom side of thebottom shell 11 of the housing 1, havingradial dampers 131 equiangularly spaced around the inside wall and anouter thread 132 extended around the periphery. - The
lock ring 14 has aninner thread 141 threaded onto theouter thread 132 of the wateroutlet pipe holder 13 and theouter thread 114 of thebottom shell 11 of the housing 1 to secure thewater outlet pipe 15 to the wateroutlet pipe holder 13, enabling thewater outlet pipe 15 to be rotated on the wateroutlet pipe holder 13 through 360°. - Referring to FIG. 4, an air hose (not shown) is connected to the
air inlet pipe 10 of the housing 1 and extended to the outside of the aquarium. An air flow rate regulator may be installed in between theair inlet pipe 10 and the air hose to control the flow rate of air. When the vane wheel 1 rotated with the motor shaft 1A, water evenly flows through thewater inlet holes 111 in different angles within 360° into thewater guide chamber 112, and guided by thetriangular vanes 121 of thevane wheel 12 and thedampers 131 of the wateroutlet pipe holder 13 toward thewater outlet pipe 15, which guides water to the aquarium or filter trough. At the same time, outside air passes through the air hose and theair inlet pipe 10 to thewater guide chamber 112 via theinside air passage 113 to mix with water flowing toward thewater outlet pipe 15. - Because the
water guide chamber 112 is a conical chamber, having a diameter gradually increasing in vertical direction from thewater inlets 111 toward thewater outlet pipe 15, water is efficiently guided to thewater outlet pipe 15 with less horsepower of the water pump motor. Thetriangular vanes 121 of thevane wheel 12 and thedampers 131 of the wateroutlet pipe holder 13 concentrate the flowing of water toward thewater outlet pipe 15, enhancing the water pumping action of the water pump motor. - A prototype of water pump motor has been constructed with the features of FIGS.2˜5. The water pump motor functions smoothly to provide all of the features discussed earlier.
- Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims. For example, water inlet pipes may be provided in the
bottom shell 11 of the housing 1 instead of thewater inlets 111.
