Description

Technical Field

[0001] This utility model relates to the field of water pumps, and more specifically to a water pump for pet water fountains. Background Technology

[0002] The water pump of a pet water fountain typically consists of two detachable parts: the pump body and the connector. The pump body houses the motor and blades connected to the motor, which are used to pump water. The connector is fitted around the blades and filters the water in the tank when the motor starts and drives the blades to pump water, preventing dirt in the tank from clogging the connector.

[0003] Existing pet water fountain pumps have grooves around the blades. When the pump body and connectors are connected, a closed flow space is formed around the blades, making it easier to draw water out of the tank. However, the grooves around the blades make cleaning them inconvenient. After cleaning the connectors, the blades need to be brushed. In addition, when the blades need to be replaced, tweezers are needed to remove the blades from the grooves, which is very time-consuming and labor-intensive.

[0004] Furthermore, the water outlet pipe of existing pet water fountains is usually located on the pump body, which means that the overall water inlet and outlet direction of the pump is fixed and cannot be adjusted according to the specifications of different pet water fountain tanks. If a different water tank is needed, the pump body must be replaced, which is costly. Utility Model Content

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0028] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0029] The embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, a water pump for a pet water fountain includes a pump body assembly 100 and a connecting assembly 200. The pump body assembly 100 includes a first housing 110, in which a rotary motor 120 is disposed. A rotating blade 130 is connected to the drive end of the rotary motor 120. The connecting assembly 200 includes a second housing 210, which is detachably connected to the first housing 110. The second housing 210 includes an inlet pipe 220 and an outlet pipe 230. A flow guiding chamber 240 is disposed within the second housing 210, which communicates with the inlet pipe 220 and the outlet pipe 230. The flow guiding chamber 240 covers the area around the rotating blade 130.

[0030] In the working state of this embodiment, the first housing 110 and the second housing 210 are first installed together, so that the pump body assembly 100 and the connecting assembly 200 are connected to each other. Then, they are placed in the water tank, with the inlet pipe 220 inside the water tank and the outlet pipe 230 extending out of the water surface. Then, the rotary motor 120 is started to drive the rotary blade 130 to rotate. During the rotation of the rotary blade 130, the water in the water tank is drawn into the guide chamber 240 through the inlet pipe 220. When the water fills the guide chamber 240, it finally flows out from the outlet pipe 230. When the rotary blade 130 needs to be maintained, it is only necessary to disassemble the first housing 110 and the second housing 210 to expose the rotary blade 130 directly to the outside, which is convenient for subsequent cleaning or replacement of the rotary blade 130.

[0031] Compared with the prior art, this application adopts a second housing 210 that is detachably connected to the first housing 110, and sets the flow guide chamber 240 and the water outlet pipe 230 on the second housing 210. In this way, when consumers need to maintain the rotating blade 130 or want to adjust the water outlet direction, they only need to disassemble or replace the second housing 210, which greatly improves the maintenance efficiency of the rotating blade 130 and saves the replacement cost applicable to different water tanks.

[0032] Furthermore, based on the above embodiments, such as Figure 2 As shown, the flow guiding chamber 240 includes an inner wall 241 and a surrounding shell 242. The surrounding shell 242 is detachably connected to the outer wall of the first shell 110, thereby forming a second shell 210 that is detachably connected to the first shell 110. The inner wall 241 and the rotating blade 130 are arranged opposite to each other. When the surrounding shell 242 is connected to the first shell 110, a closed flow guiding space is formed between the inner wall 241 and the rotating blade 130. Thus, when the rotating blade 130 rotates, water in the water tank is drawn into the space between the inner wall 241 and the rotating blade 130 through the inlet pipe 220, and then flows out through the outlet pipe 230.

[0033] Furthermore, based on the above embodiments, such as Figure 2As shown, a guide plate 243 is provided on the inner wall 241. When the casing 242 is connected to the outer wall of the first casing 110, the guide plate 243 partially covers the area around the rotating blade 130. The water inlet pipe 220 is connected to the inner wall 241, and the water outlet pipe 230 is connected to the casing 242 through the guide plate 243. By providing the guide plate 243 to partially cover the area around the rotating blade 130, the closed flow space formed between the inner wall 241 and the rotating blade 130 is smaller when the casing 242 and the first casing 110 are connected. In this way, after the water in the tank is drawn into the area between the inner wall 241 and the rotating blade 130 through the water inlet pipe 220, the space will be filled more quickly due to the smaller flow space, and the pressure in the flow chamber 240 will increase, thereby increasing the water output speed.

[0034] This application also provides a second embodiment of the flow guiding chamber 240, which differs structurally from the first embodiment of the flow guiding chamber 240, such as... Figure 3 As shown, the water outlet pipe 230 communicates with the inner wall 241 through the guide plate 243. The first embodiment of the guide chamber 240 is characterized by the water inlet and outlet directions being on different sides. Therefore, the entire pump assembly 100 and the connecting assembly 200 can be placed horizontally, thus making it suitable for the water tank of a conventional pet water fountain. The second embodiment of the first guide chamber 240 is characterized by the water inlet and outlet directions being on different sides. Therefore, the entire pump assembly 100 and the connecting assembly 200 can be placed vertically, thus making it suitable for the water tank of a pet water fountain that is narrower in width but taller in height. As can be seen from the above embodiments, this application can change the water outlet path by replacing different connecting assemblies 200, thus making it suitable for pet water fountains of different specifications.

[0035] Furthermore, based on the above embodiments, combined with Figure 2 , Figure 3 and Figure 6 As shown, a snap-fit ​​block 244 is provided on the inner side of the housing 242. The first housing 110 is recessed inward to form a limiting step 111. A groove 112 is provided on the limiting step 111. When the second housing 210 is connected to the first housing 110, the housing 242 is aligned with the limiting step 111 and inserted, so that the snap-fit ​​block 244 is snapped into the groove 112 to form an interference fit, thereby realizing the detachable connection between the second housing 210 and the first housing 110.

[0036] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5As shown, a filter chamber 250 is provided on the side of the flow guiding chamber 240 away from the rotating blade 130. The filter chamber 250 is connected to the water inlet pipe 220. A filter element 251 is installed in the filter chamber 250. When the rotating blade 130 is rotating and pumping water, the water in the water tank will be filtered through the filter element 251 before entering the flow guiding chamber 240 through the water inlet pipe 220. This can prevent dirt from the water tank from entering the flow guiding chamber 240 and thus clogging the water outlet pipe 230.

[0037] Furthermore, based on the above embodiments, combined with Figure 4 and Figure 5 As shown, a filter plate 252 is provided on the outer wall of the filter chamber 250. When the rotating blade 130 rotates to pump water, the hair in the water tank will be blocked by the filter plate 252, thereby preventing blockage of its inlet pipe 220.

[0038] Furthermore, based on the above embodiments, such as Figure 1 As shown, a wire 113 is provided on the first housing 110, and the wire 113 is electrically connected to the rotary motor 120 to provide electrical energy to the rotary motor 120.

[0039] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
