Description

Technical Field

[0001] This utility model belongs to the field of water pump accessories, and specifically relates to a water pump controller cover. Background Technology

[0002] As a key component of a water pump system, the normal operation of the pump controller is crucial to the stability of the entire system. However, external environmental factors such as dust, impurities, and water splashes can damage the pump controller, and human factors such as collisions and accidental touches can also cause damage. A housing provides a certain degree of buffering and protection, reducing the impact of these unexpected factors on the pump controller. It can also reduce noise and vibration during operation, improving user comfort. However, the existing housing is a single, non-removable unit. When the controller or motor inside malfunctions, maintenance personnel cannot easily access the fault point for repair or replacement, requiring destructive removal of the housing. This can lead to lengthy repair times or even require shutting down the entire equipment, thus impacting production or operational efficiency. Furthermore, dust, dirt, or other contaminants may accumulate inside the housing, and this structure prevents the cleaning of the controller and motor. Utility Model Content

[0003] To address the problems of inconvenient maintenance and cleaning associated with existing non-removable housings, this utility model provides a water pump controller housing with a detachable structure, facilitating maintenance, replacement, and cleaning.

[0004] The present invention adopts the following technical solution: a water pump controller housing, comprising a housing body having an enclosing space and a housing cover detachably fitted with the housing body. The top of the housing body is provided with a top edge, and the side wall of the housing cover is provided with a downwardly extending buckle. The buckle has a connected hook and a recess. The hook can be engaged from bottom to top at the bottom of the top edge. A gap is formed between the recess and the top edge. By applying force to the surface of the recess, the hook is disengaged from the top edge, thereby realizing the detachable connection between the housing cover and the housing body.

[0005] The buckle formed by the recess and the hook has good elasticity and can deform inward under external force until the buckle separates from the top edge. In this way, the shell body and the shell cover form a detachable structure, which can solve the problems of inconvenient maintenance and cleaning.

[0006] As an improvement, the latch has two hooks, and the recess is arranged horizontally side by side with the two hooks and located between the two hooks. The recess separates the two hooks, and the entire latch has good elasticity when force is applied only at the recess, so that it can deform inward under the action of external force until the latch separates from the top edge.

[0007] As another improvement, the recess is located above the hook. To ensure the strength of the latch, the latch width of this structure can be appropriately set to be slightly wider to facilitate the application of force.

[0008] Furthermore, a notch is provided between the buckle and the side wall of the cover. This design allows for greater freedom of movement of the buckle, resulting in better elasticity and easier deformation under external force, thus reducing the difficulty of deformation.

[0009] Furthermore, the shell body is provided with two water-retaining flanges, both of which are connected to the top edge. The two water-retaining flanges are spaced apart to form two openings, and the buckle is disposed at one of the openings. The water-retaining flanges form a water-blocking structure, which can provide a certain degree of isolation to reduce water falling onto the controller surface in the operating environment, thus protecting the controller. Water on the surface of the water-retaining flanges can be discharged downwards through the provided openings, effectively preventing accumulation.

[0010] Furthermore, the cover is provided with a bending member, which is symmetrically arranged with the buckle and cooperates with another opening to form a reliable connection. There is no gap between the bending member and the main body of the cover. During disassembly, only the buckle is subjected to force, and the bending member acts as a limit, and the symmetrical force distribution facilitates disassembly and assembly.

[0011] Furthermore, the water pump controller housing also has a base with a drain hole, and the base is provided with an upwardly extending flange. A rotating clip provided at the lower part of the housing body can be detachably engaged with the flange. One end of the housing body is provided with a rotating shaft and the other end is provided with a hook-shaped part. The rotating clip is rotatably connected to the lower part of the housing body through the rotating shaft, and the hook-shaped part can be detachably engaged with the flange.

[0012] Furthermore, the hook-shaped portion has a limiting cavity, which is recessed downwards within the hook-shaped portion. The side of the retaining flange is recessed to form a concave cavity, and a downwardly extending limiting buckle is provided at the top of the concave cavity. By rotating the rotating locking member, the limiting buckle can engage with or disengage from the limiting cavity, thereby achieving a detachable fit between the base and the shell body. When the hook-shaped portion and the limiting buckle at the top of the concave cavity just come into contact, the engagement force is along the tangential direction of the rotating locking member's rotation. When the hook-shaped portion and the limiting buckle at the top of the concave cavity are tightly engaged, the engagement force is along the vertical direction. This ensures the strength of the fit and prevents the two from easily disengaging.

[0013] Furthermore, the inner wall of the shell body is provided with a plurality of reinforcing ribs, and the bottom of the reinforcing ribs and the inner wall of the shell body form an assembly area with the opening facing downward, and the top of the flange is clamped in the assembly area from bottom to top.

[0014] Furthermore, a clearance opening is provided on one side of the main body of the housing, and a first heat dissipation grille is provided above the clearance opening. A second heat dissipation grille is also provided on the main body of the housing, and the second heat dissipation grille is arranged opposite to the clearance opening. The rotating shaft of the motor can extend from the clearance opening, and convection can be formed between the oppositely arranged first and second heat dissipation grilles to quickly dissipate the heat generated by the controller and the motor.

[0015] The beneficial effects of this utility model are as follows: This application relates to a water pump controller cover. The buckle formed by the recess and the hook has good elasticity and can deform inward under external force until the buckle separates from the top edge. In this way, the main body and the cover form a detachable structure, which can solve the problems of inconvenient maintenance and cleaning. In addition, the base and the main body of the cover also form a detachable connection, which can also solve the problems of inconvenient maintenance and cleaning. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0024] Example 1

[0025] This embodiment is a water pump controller housing, such as Figures 1 to 6 As shown, the device includes a shell body 1 with an enclosing space and a shell cover 2 that is detachably fitted to the shell body 1. The shell body 1 has a top edge 11, and the shell cover 2 has a downwardly extending buckle 21 on its side wall. The buckle 21 has a hook 211 and a recess 212 connected together. The hook 211 can be engaged from bottom to top at the bottom of the top edge 11. A gap is formed between the recess 212 and the top edge 11. By applying force to the surface of the recess 212, the hook 211 is disengaged from the top edge 11, thereby achieving a detachable connection between the shell cover 2 and the shell body 1. In this embodiment, the space enclosed by the shell body 1 can accommodate the controller and the motor, thus protecting the controller and the motor.

[0026] Two hooks 211 are provided, and the recess 212 is arranged horizontally side by side with the two hooks 211 and located between the two hooks 211. The recess 212 separates the two hooks 211, and the entire buckle 21 has good elasticity when force is applied only at the recess 212, so that it can deform inward under the action of external force until the buckle 21 separates from the top edge 11. A notch 22 is provided between the buckle 21 and the side wall of the shell cover 2. This design allows the buckle 21 to move more freely back and forth, thus having better elasticity, making it easier to deform under the action of external force, and reducing the difficulty of deformation.

[0027] The main body 1 of the casing has two water-retaining flanges 12, both of which are connected to the top edge 11. The two water-retaining flanges 12 are spaced apart to form two openings 13, and the buckle 21 is located at the first opening 13. The water-retaining flanges 12 form a water-blocking structure, providing a certain degree of protection to reduce water falling onto the controller surface from the operating environment. Water on the surface of the water-retaining flanges 12 can be discharged downwards through the openings 13, effectively preventing accumulation.

[0028] The cover 2 is provided with a bending member 23, which is symmetrically arranged with the buckle 21 and fits at the second opening 13 to form a reliable connection. There is no gap between the bending member 23 and the main body 1. During disassembly, only the buckle 21 is subjected to force, and the bending member 23 plays a limiting role. Symmetrical force distribution facilitates disassembly and assembly.

[0029] The water pump controller housing also has a base 3 with a drain hole 31. The base 3 is provided with an upwardly extending flange 32. A rotating clip 24 located at the lower part of the housing body 1 can be detachably engaged with the flange 32. One end of the housing body 1 is provided with a rotating shaft 241 and the other end is provided with a hook-shaped part 242. The rotating clip 24 is rotatably connected to the lower part of the housing body 1 through the rotating shaft 241. The hook-shaped part 242 can be detachably engaged with the flange 32. The hook-shaped portion 242 has a limiting cavity 243, which is recessed from top to bottom within the hook-shaped portion 242. The side of the retaining flange 32 is recessed to form a cavity 321, and the top of the cavity 321 has a downwardly extending limiting buckle 322. By rotating the rotating locking member 24, the limiting buckle 322 can engage with or disengage from the limiting cavity 243, thereby achieving a detachable fit between the base 3 and the shell body 1. When the hook-shaped portion 242 just contacts the limiting buckle 322 at the top of the cavity 321, the engagement force is along the tangential direction of the rotation direction of the rotating locking member 24. When the hook-shaped portion 242 is tightly engaged with the limiting buckle 322 at the top of the cavity 321, the engagement force is along the vertical direction. This ensures the strength of the fit and prevents the two from easily disengaging.

[0030] The inner wall of the shell body 1 is provided with a plurality of reinforcing ribs 18. The bottom of the reinforcing ribs 18 and the inner wall of the shell body 1 form an assembly area 19 with the opening 13 facing downward. The top of the retaining flange 32 is clamped from bottom to top in the assembly area 19. The bottom of the shell body 1 has one or two mounting ports 17, preferably two mounting ports 17. The inner side of each mounting port 17 is provided with two reinforcing ribs 18. The lower part of the two reinforcing ribs 18 is provided with mounting holes 181. The rotating shaft 241 of the rotating clip 24 is inserted into the mounting hole 181. When the rotating clip 24 is set at the mounting port 17, the bottom wall of the rotating clip 24 is flush with the bottom wall of the shell body 1. To facilitate the assembly of the rotating shaft 241, the rotating shaft 241 can be designed to be telescopic, or a notch 182 can be provided in one of the mounting holes 181. In this way, when installing the rotating shaft 241, one end of the rotating shaft 241 is first installed in the mounting hole 181 without the notch 182, and the other end enters the mounting hole 181 through the notch 182. In this structure, the bottom of the shell body 1 can be inserted into the retaining flange 32 of the base 3 to form a preliminary positioning. When the rotating clip 24 cooperates with the limiting buckle 322, the shell body 1 and the base 3 are not easily separated, forming a reliable connection. After the rotating clip 24 separates from the limiting buckle 322, the shell body 1 can be easily disassembled, reducing the difficulty of disassembly and assembly.

[0031] A clearance opening 14 is provided on one side of the housing body 1. A first heat dissipation grille 15 is provided above the clearance opening 14. A second heat dissipation grille 16 is also provided on the housing body 1, and the second heat dissipation grille is arranged opposite to the clearance opening 14. The rotating shaft of the motor can extend from the clearance opening 14. The controller is located between the first heat dissipation grille 15 and the second heat dissipation grille 16. The first heat dissipation grille 15 and the second heat dissipation grille 16 arranged opposite to each other can form convection, which can quickly dissipate the heat generated by the controller and the motor.

[0032] The buckle 21, formed by the recess 212 and the hook 211, has good elasticity and can deform inward under external force until the buckle 21 separates from the top edge 11, forming a detachable connection between the shell body 1 and the shell cover 2. By rotating the locking piece 24 and the retaining flange 32, a detachable connection between the base 3 and the shell body 1 is achieved. During maintenance, the locking piece 24 can be opened first to remove the shell body 1 and the shell cover 2 together. Alternatively, external force can be applied to the recess 212 with a tool to remove the shell cover 2. At this time, the shell body 1 and the base 3 are still connected as one unit, effectively solving the problems of inconvenient maintenance and cleaning.

[0033] Example 2

[0034] The difference between this embodiment and Embodiment 1 is that the recess 212 is located above the hook 211. To ensure the strength of the buckle 21, the width of the buckle 21 in this structure can be appropriately set to be slightly wider to facilitate the application of force.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
