[0036] Among them, the pump body 100 is provided with a cooling groove 110 and a first water inlet channel.

[0037] Among them, the pump cover 200 is connected to the pump body 100, a working chamber 300 is formed between the pump cover 200 and the pump body 100, and the pump cover 200 is provided with a water inlet 210, a water outlet 220, a second water inlet channel, and a water outlet channel.

[0038] Specifically, the water inlet 210 is in communication with the working chamber 300, the water outlet 220 is in communication with the working chamber 300, one end of the first water inlet passage is in communication with the water inlet 210, one end of the second water inlet passage is in communication with the other end of the first water inlet passage, the other end of the second water inlet passage is in communication with the inlet of the cooling tank 110, one end of the water outlet passage is in communication with the outlet of the cooling tank 110, and the other end of the water outlet passage is in communication with the working chamber 300.

[0039] Wherein, the cooling plate 400 is connected to the pump body 100 and covers the cooling tank 110.

[0040] Wherein, the controller 500 is connected to the cooling plate 400.

[0041] Specifically, the central processing unit of the controller 500 is located at a position corresponding to the cooling plate 400 and the cooling tank 110 for cooling the core important components.

[0042] In this embodiment, in addition to entering the water outlet 220 through the working chamber 300, the water at the water inlet 210 can also enter the cooling tank 110 through the first water inlet passage and the second water inlet passage, and the cooling plate 400 cools the controller 500, takes away the heat of the controller 500, and then returns to the working chamber 300 through the water outlet passage, which can both perform cooling and will not cause waste of water.

[0043] Such as Figures 1 - 6 As shown, on the basis of the above embodiment, the second water inlet passage includes a first water inlet hole and a second water inlet hole. One end of the first water inlet hole is in communication with the water inlet 210, one end of the second water inlet hole is in communication with the first water inlet passage, and the first water inlet hole is in communication with the second water inlet hole.

[0044] No specific limitation is made on the structural shapes of the first water inlet hole and the second water inlet hole herein.

[0045] In this embodiment, the second water inlet passage is subdivided into the first water inlet hole and the second water inlet hole, which is convenient for the processing and forming of the second water inlet passage.

[0046] Such as Figures 1 - 6 As shown, on the basis of the above embodiment, a plugging member (not shown in the figure) is further included. The first water inlet hole is a first through hole 230, the second water inlet hole is a first blind hole 240, one end of the first through hole 230 is in communication with the water inlet 210, the other end of the first through hole 230 is in communication with the outside and is blocked by the plugging member, one end of the first blind hole 240 is in communication with the second water inlet passage, and the other end of the first blind hole 240 is in communication with the first through hole 230.

[0047] To ensure the processing efficiency and the final circulation efficiency, the first through hole 230 and the first blind hole 240 are straight holes.

[0048] In this embodiment, the first water inlet hole is the first through hole 230, and the second water inlet hole is the first blind hole 240. It is possible to drill a hole through from a position outside the pump cover 200 in the direction of the water inlet 210, and drill a hole through from another position outside the pump cover 200 in the direction of the first through hole 230 and seal the part where the first through hole 230 communicates with the outside, then the rapid processing and forming of the second water inlet channel can be completed.

[0049] As Figures 1 - 6 shown, on the basis of the above embodiment, the first water inlet channel includes a third water inlet hole and a fourth water inlet hole. One end of the third water inlet hole communicates with the second water inlet channel, one end of the fourth water inlet hole communicates with the inlet of the cooling tank 110, and the third water inlet hole communicates with the fourth water inlet hole.

[0050] Here, no specific limitations are imposed on the structural shapes of the third water inlet hole and the fourth water inlet hole.

[0051] In this embodiment, the first water inlet channel is subdivided into a third water inlet hole and a fourth water inlet hole, which is convenient for the processing and forming of the first water inlet channel.

[0052] As Figures 1 - 6 shown, on the basis of the above embodiment, the third water inlet hole is the second blind hole 120, the fourth water inlet hole is the third blind hole 130. One end of the second blind hole 120 communicates with the second water inlet channel, one end of the third blind hole 130 communicates with the inlet of the cooling tank 110, and the other end of the third blind hole 130 communicates with the second blind hole 120.

[0053] To ensure the processing efficiency and the final circulation efficiency, the second blind hole 120 and the third blind hole 130 are straight holes.

[0054] In this embodiment, the third water inlet hole is the second blind hole 120, and the fourth water inlet hole is the third blind hole 130. It is possible to drill a hole from a position of the cooling tank 110 in the direction of the water inlet 210, and drill a hole through from a position outside the pump body 100 in the direction of the second blind hole 120, then the rapid processing and forming of the first water inlet channel can be completed.

[0055] As Figures 1 - 6 shown, on the basis of the above embodiment, the water outlet channel is the second through hole 140. One end of the second through hole 140 communicates with the outlet of the cooling tank 110, and the other end of the second through hole 140 communicates with the working chamber 300.

[0056] In this embodiment, the water outlet channel is the second through hole 140, and a hole can be drilled from a position of the cooling tank 110 far away from the third blind hole 130 in the direction of the working chamber 300 to quickly machine and form the water outlet channel.

[0057] As Figures 1 - 6 shown, on the basis of the above embodiment, the cooling tank 110 is distributed along a serpentine path.

[0058] In this embodiment, the cooling tank 110 is distributed along a serpentine path. Specifically, starting from one end, it moves along one row to the other end, then turns to the adjacent row and returns in the opposite direction until the entire area is covered, ensuring that the path does not repeat and is comprehensively covered to increase the cooling area as much as possible.

[0059] Specifically, the cooling tank 110 includes a transverse portion 111 and a longitudinal portion 112. The transverse portion 111 is distributed along the length direction of the cooling plate 400, and the longitudinal portion 112 is distributed along the width direction of the cooling plate 400. Each transverse portion 111 and each longitudinal portion 112 are sequentially and alternately connected to form the cooling tank 110 distributed along a serpentine path.

[0060] As Figures 1 - 6 shown, an electronic water pump includes the above-described electronic water pump cooling structure.

[0061] As Figures 1 - 6 shown, on the basis of the above embodiment, it further includes an impeller 600. The impeller 600 is located in the working chamber 300, and the impeller 600 can rotate relative to the pump body 100 to drive water to move from the water inlet 210 toward the water outlet 220.

[0062] In this embodiment, the impeller 600 can rotate relative to the pump body 100 to drive water to move from the water inlet 210 toward the water outlet 220. At the same time, it can drive water to enter the cooling tank 110 through the first water inlet channel and the second water inlet channel, and cool the controller 500 through the cooling plate 400, take away the heat of the controller 500, and then flow back to the working chamber 300 through the water outlet channel.

[0063] As Figures 1 - 6 shown, on the basis of the above embodiment, it further includes a motor assembly 700. The motor assembly 700 is located in the pump body 100. The impeller 600 is connected to the motor assembly 700. The motor assembly 700 can drive the impeller 600 to rotate. The controller 500 is electrically connected to the motor assembly 700 and can control the operation of the motor assembly 700.

[0064] Specifically, the motor assembly 700 includes a stator and a rotor. The stator is connected to the pump body 100, the impeller 600 is connected to the rotor, and the rotor can rotate relative to the stator and drive the impeller 600 to rotate.

[0065] In this embodiment, the controller 500 is electrically connected to the motor assembly 700 and can control whether the motor assembly 700 operates, thereby controlling whether the impeller 600 rotates.

[0066] It is also worth noting here that when the temperature is too high, the controller 500 can control the motor assembly 700 to increase the rotation speed of the impeller 600, thereby indirectly accelerating the flow rate of water in the cooling tank 110 and enhancing the cooling effect on the controller 500.

[0067] It is also worth noting here that as Figures 1 - 6 described, this double-headed water pump can be used for household faucets. One impeller 600 can rotate relative to the pump body 100 to drive cold water to move from the water inlet 210 to the water outlet 220, and the other impeller 600 can rotate relative to the pump body 100 to drive hot water to move from the water inlet 210 to the water outlet 220.

[0068] Furthermore, this electronic water pump cooling structure is used for the part corresponding to the intake of cold water, that is, the impeller 600 can rotate relative to the pump body 100 to drive cold water to move from the water inlet 210 to the water outlet 220. At the same time, in addition to entering the water outlet 220 through the working chamber 300, the water at the water inlet 210 can also enter the cooling tank 110 through the first water inlet channel and the second water inlet channel, and cool the controller 500 through the cooling plate 400, taking away the heat of the controller 500. At this time, the cold water is heated, so it can also achieve the effect of discharging hot water.
