Description

Technical Field

[0001] This utility model belongs to the field of water treatment devices, and specifically relates to a water pump suitable for water treatment. Background Technology

[0002] When existing water treatment pumps are operating in the working environment, the entire pump is prone to water splashing. Since the top of the pump is the motor, and the top of the motor is the fan for heat dissipation, the connection between the fan and the motor output shaft is usually a flat plane. The direction of the fan blades is basically the same as this plane. When water splashes onto this plane during use, it lacks the power to move under the premise of low rotation speed, and it is easy to remain on the surface of the fan blades. Then it is easy to flow into the motor through the mating gap. Since the motor is connected to the power supply, the accumulated water will cause excessive current and damage the stator and rotor. Therefore, the existing water pump structure needs to be modified to avoid this problem. Utility Model Content

[0003] To address the problem of existing water pumps being easily damaged by water accumulation due to unreasonable design, this utility model provides a water pump suitable for water treatment. By installing a fan blade on the top of the motor, water remaining on the surface of the fan blade is thrown out, thereby reducing water residue and the problem of easy damage.

[0004] The technical solution adopted by this utility model is as follows: A water pump suitable for water treatment, comprising, arranged sequentially from bottom to top:

[0005] seat body;

[0006] The pump body is connected to the base body;

[0007] An electric motor having an output shaft;

[0008] The fan blade and the pump body are respectively connected to the upper and lower ends of the output shaft; the fan blade includes a base and arc-shaped blades disposed on the base, with adjacent blades spaced apart to form a water flow channel;

[0009] The base is high in the middle and low at the edges, and is connected to the output shaft. The blade has a flange section and an extension section, and the extension section gradually rises from the center of the base toward the flange section.

[0010] In this application, the fan blade is located at the top of the motor. It has a base that is low in the middle and high at the edges, and blades with a reasonable structural design. When the water pump is working, water droplets in the environment fall onto the surface of the fan blade and are thrown out by centrifugal force. Compared with traditional blades, its centrifugal effect is obvious, the throwing effect is good, and water is less likely to remain. A funnel-shaped water flow channel is formed between two adjacent blades, which effectively reduces water residue.

[0011] Furthermore, a water-retaining disc is connected to the top of the flange section. The water-retaining disc is annular, and the flange section is connected to the lower part of the water-retaining disc. The annular water-retaining disc can ensure heat dissipation of the blades and also block the water thrown out under the action of centrifugal force, causing it to flow downwards.

[0012] Furthermore, the motor is provided with a skeleton oil seal at its end, and the output shaft extends from the center of the skeleton oil seal to prevent water from entering the motor along the output shaft.

[0013] The motor is also equipped with a controller, which is connected to the motor and is used to control the start, stop and speed of the motor. The controller and the motor are respectively provided with a first wire hole and a second wire hole. The first wire hole and the second wire hole are filled with rubber plugs to achieve a sealed connection between the motor and the controller.

[0014] Furthermore, the controller has a base box, on which a heat dissipation unit formed by multiple heat sinks is provided, and a sealing ring is provided at the mating point between the heat dissipation unit and the base box. The heat sinks and the base box are separate units, which facilitates complete assembly and allows for replacement with the required size as needed.

[0015] Furthermore, the motor has a fan shroud located outside the fan blades, and the fan shroud has a raised edge that covers the outside of the heat dissipation unit.

[0016] Furthermore, the motor is provided with an observation port, which is close to the pump body. The output shaft can be observed through the observation port. A waterproof ring is fitted on the output shaft to block water from rushing up the pump body.

[0017] Furthermore, a water guide surface is provided at the observation port, and the water guide surface is higher on the inside and lower on the outside.

[0018] Furthermore, the motor has at least two mounting holes on its side, each with internal threads, and a plug with a sealing gasket is provided at each mounting hole. These mounting holes prevent water from entering the motor during vertical installation, and can also be used for horizontal installation.

[0019] The beneficial effects of this utility model are as follows: This application discloses a water pump suitable for water treatment. The impeller has a water flow channel and a base that is low in the middle and high at the edges, which can discharge water and reduce residue. The blades are designed to throw water out, and a funnel-shaped water flow channel is formed between adjacent blades, which effectively reduces water residue. The annular baffle plate can ensure heat dissipation of the blades and also block the water thrown out under centrifugal force, causing it to flow downward. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] This embodiment provides a water pump suitable for water treatment, such as... Figures 1 to 8 As shown, it includes the following arranged sequentially from bottom to top:

[0031] The base 1 has a water inlet 11 on its side and the bottom of the base 1 is hollow.

[0032] Pump body 2 is connected to the base 1; the pump body 2 is equipped with an impeller for accelerating the fluid.

[0033] The motor 3 has an output shaft 38 and a barrel. The end of the barrel is provided with a connecting sleeve 37, and the connecting sleeve 37 is provided with a water outlet 371.

[0034] like Figure 7 and Figure 8 As shown, the fan blade 4 and the pump body 2 are respectively connected to the upper and lower ends of the output shaft 38; the fan blade 4 includes a base 41 and arc-shaped blades 42 disposed on the base 41, with two adjacent blades 42 spaced apart to form a water flow channel A; the top of the baffle plate 43 has an annular surface, which is higher inside and lower outside, effectively reducing water accumulation;

[0035] The base 41 is high in the middle and low at the edges. The blade 42 has a flange section 421 and an extension section 422. The flange section 421 is connected to the lower part of the water baffle plate 43. The top of the extension section 422 has an inclined surface. The inclined surface gradually rises from the center of the blade 4 towards the water baffle plate 43. Furthermore, the extension section 422 gradually rises from the center of the base 41 towards the flange section 421.

[0036] In this application, the fan blade 4 is located at the top of the motor 3. When the water pump is working, water droplets from the environment fall onto the surface of the fan blade 4 and are thrown out under the action of centrifugal force. Compared with the traditional blade 42, its centrifugal effect is obvious, the throwing effect is better, and water is less likely to remain. The blade 42 has an inclined surface, and a funnel-shaped water flow channel A is formed between two adjacent blades 42, which effectively reduces water residue. The annular water baffle 43 can ensure the heat dissipation of the blade 42 and also block the water thrown out under the action of centrifugal force, allowing it to flow downward.

[0037] Compared to the extension section 422, the slope of the flange section 421 is significantly smaller. The water baffle 43 is connected to the flange section 421. This arrangement can reduce water residue.

[0038] The motor 3 is provided with a skeleton oil seal 32 at its end, and the output shaft 3831 passes through the center of the skeleton oil seal 32 to prevent water from entering the motor 3 along the output shaft 3831.

[0039] The motor 3 is also equipped with a controller 5, which is connected to the motor 3 and is used to control the start, stop and speed of the motor 3. The controller 5 and the motor 3 are respectively provided with a first wire hole 51 and a second wire hole 33. The first wire hole 51 and the second wire hole 33 are filled with rubber plugs to achieve a sealed connection between the motor 3 and the controller 5.

[0040] The controller 5 has a base box 52, on which a heat dissipation unit 53 is formed by multiple heat sinks 531. A sealing ring 522 is provided at the mating point between the heat dissipation unit 53 and the base box 52. The heat sinks 531 and the base box 52 are separately arranged for easy assembly and can be replaced with the required size as needed. The base box 52 also has a guide surface 521, which is located below the heat dissipation unit 53.

[0041] The motor 3 has a fan cover 6 located outside the fan blade 4. The fan cover 6 has a raised edge 61 that shields the outside of the heat dissipation unit 53. In this arrangement, the raised edge 61 can prevent water from splashing onto the heat dissipation unit 53.

[0042] The motor 3 is equipped with an observation port 36, which is located near the pump body 2. The output shaft 38 can be observed through the observation port 36. A waterproof ring 31 is fitted onto the output shaft 38 to prevent water from surging up the pump body 2. Specifically, the observation port 36 is located on the connecting sleeve 37. Because the entire water pump has a vertical structure, assembly often starts from one side. The pump body 2 needs to be fitted onto the output shaft 38 of the motor 3 so that the motor 3 can drive the impeller built into the pump body 2. Therefore, an observation port 36 is needed to check whether the assembly is in place to prevent accidental detachment.

[0043] A water-guiding surface 372 is provided at the observation port 36, and the water-guiding surface 372 is shaped with the inner side higher than the outer side. That is, the water-guiding surface 372 can be observed through the observation port 36. If water blocked by the waterproof ring 31 flows onto the water-guiding surface 372, it will be discharged outward through the water-guiding surface 372. Specifically, the water-guiding surface 372 is provided on the connecting sleeve 37.

[0044] The motor 3 has at least two mounting holes 34 on its side. Each mounting hole 34 has an internal thread and a plug 35 with a sealing gasket is provided at each mounting hole 34. The mounting holes 34 are provided to prevent water from entering the motor 3 during vertical installation. The mounting holes 34 can also be used for horizontal installation.

[0045] 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.
