By constructing the motor cavity and the heat exchange cavity inside the casing, a coolant inlet channel is provided in the casing wall, and a first reflux channel is provided in the main shaft, the pump casing and the casing jointly construct a pump body cavity.

[0004] However, when the coolant stops flowing, the coolant will be stored inside the casing for a long time. But when the motor just starts to stop rotating, the residual heat in the motor cannot be dissipated, causing the residual heat in the motor to heat the coolant. This will cause the coolant to lose efficiency when cooling for a long time.

[0005] Therefore, those skilled in the art have proposed an electronic water pump for automobile maintenance teaching to solve the problems raised by the background technology. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model utilizes the rotating connection between the cam and the rotating plate so that the cam contacts the top of the rotating plate when it rotates, and contacts the rotating plate when the cam rotates. At the same time, the movable rod drives the spring to stretch when it moves downward, and utilizes the connecting rod between the movable rod and the fixed box to push the air in the fixed box to the inside of the sleeve. When the cam is away from the top of the rotating plate, the reverse force of the spring is utilized to make the spring drive the rotating plate to move upward, and at the same time, the rotating plate drives the air in the fixed box to flow, and utilizes a hose to make the water flow in the cooling box enter the inside of the fixed box, and utilizes the water tank on one side of the fixed box to circulate the coolant inside the motor, thereby achieving the cooling effect on the motor.

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] Embodiment 1: The utility model provides an electronic water pump for automobile maintenance teaching, including a base 1, a motor 2 arranged on the top of the base 1, a heat dissipation mechanism 3 arranged on the top of the base 1, a fixing mechanism 4 arranged on the top of the base 1, and a water inlet pipe 5 arranged on the side wall of the fixing mechanism 4.

[0027] Furthermore, the heat dissipation mechanism 3 includes a cooling box 301, a hose 302 arranged on the top of the cooling box 301, a sleeve 303 arranged on the top of the base 1, a fixed plate 304 arranged in the sleeve 303, a movable rod 306 arranged at the bottom of the fixed plate 304, a spring 307 arranged at the bottom of the fixed plate 304, a rotating plate 308 arranged outside the movable rod 306, a fixed box 309 arranged in the sleeve 303, and a cam 305 arranged at one end of the motor 2.

[0028] Furthermore, the fixed plate 304 and the movable rod 306 are provided in two groups, the side walls of the two groups of fixed plates 304 are fixedly connected to the side walls of the sleeve 303, one end of the movable rod 306 is hinged to the bottom of the fixed plate 304, one end of the spring 307 is fixed to the top of the movable rod 306, the rotating plate 308 is hinged to the other end of the movable rod 306, the cam 305 is internally rotatably connected to one end of the motor 2, and one end of the hose 302 is embedded in the interior of the sleeve 303.

[0029] Furthermore, the fixing mechanism 4 includes a tube body 401 , an impeller 403 disposed in the tube body 401 , an air inlet pipe 404 disposed at the top of the tube body 401 , a baffle 402 disposed at the top of the air inlet pipe 404 , and a groove 405 disposed in the motor 2 .

[0030] Furthermore, the side wall of the impeller 403 is rotatably connected to the inside of the tube body 401 , and one end of the air inlet pipe 404 is embedded in the inside of the tube body 401 .

[0031] Furthermore, the bottom of the tube body 401 is fixedly connected to the top of the base 1 , and a water tank 6 is provided in the motor 2 .

[0032] As can be seen from the above, the rotation of the motor 2 drives the cam 305 to rotate when the motor 2 rotates, and the rotation connection between the cam 305 and the rotating plate 308 is used to make the cam 305 contact the top of the rotating plate 308 when it rotates, and the rotating plate 308 is contacted by the cam 305 when it rotates, so that the rotating plate 308 moves downward, and at the same time, when the rotating plate 308 moves downward, it drives one end of the movable rod 306 to move downward synchronously, and at the same time, when the movable rod 306 moves downward, it drives the spring 307 to stretch, and when the movable rod 306 and the fixed box 309 are used, the connecting rod is used to drive the connecting rod downward when the movable rod 306 moves downward, so that the air in the fixed box 309 is pushed to the inside of the sleeve 303, and when the cam 305 is away from the sleeve 303, the movable rod 306 moves downward, and the connecting rod is used to move downward when the movable rod 306 moves downward, so that the air in the fixed box 309 is pushed to the inside of the sleeve 303. When the top of the rotating plate 308 is reached, the reverse force of the spring 307 is utilized to make the spring 307 drive the rotating plate 308 to move upward, and at the same time, the rotating plate 308 drives the air in the fixed box 309 to flow, and the hose 302 is utilized to make the water flow in the cooling box 301 enter the interior of the fixed box 309, and the water tank 6 on one side of the fixed box 309 is utilized to make the coolant circulate inside the motor 2 to achieve the cooling effect on the motor. When the motor 2 stops rotating, the coolant in the sleeve 303 is caused to enter the interior of the fixed box 309 under the action of the water flow. It is worth noting that the support plate in the fixed box 309 has a fan-shaped symmetrical opening, and the contact between the rotating plate 308 and the cam 305 is utilized. , the cam 305 rotates rapidly to push the rotating plate 308 to move rapidly, and the fast movement of the supporting plate in the fixed box 309 is used to form a suction force on the cooling box 301, so that the coolant in the cooling box 301 enters the fixed box 309. When the rotating plate 308 stops moving, the coolant in the motor 2 will flow back to the inside of the fixed box 309, and through the gap of the supporting plate in the fixed box 309, the coolant passes through the fixed box 309 and enters the inside of the hose 302. At the same time, the coolant in the hose 302 enters the inside of the cooling box 301. The coolant is isolated by the cooling box 301 to avoid the cooling efficiency of the coolant from decreasing. By pulling the baffle 402, the baffle 402 The top of the air inlet pipe 404 is separated, and the motor 2 rotates to drive the impeller 403 to rotate. The impeller 403 drives the air to enter the inside of the tube body 401 by utilizing the rotation of the impeller 403. The air driven by the impeller 403 enters the inside of the groove 405 through the groove 405 provided in the motor 2. The rotation of the impeller 403 causes the heat in the motor 2 to flow to the vicinity of the groove 405. The flow of air in the groove 405 achieves a cooling effect on the motor 2. The water flows through the water inlet pipe 5 on the side wall of the tube body 401 through the water inlet pipe 5 on the top side of the tube body 401 into the inside of the tube body 401, and the water flow is pressurized through the tube body 401.

[0033] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the fixing mechanism 4 includes a tube body 401, an impeller 403 arranged in the tube body 401, an air intake pipe 404 arranged at the top of the tube body 401, a baffle 402 arranged at the top of the air intake pipe 404, and a groove 405 arranged in the motor 2.

[0034] From the above, it can be seen that when the motor 2 is in an environment with a lot of dust, in order to ensure the normal rotation of the impeller 403, the air intake pipe 404 is dust-proofed by pushing the external filter net to avoid dust accumulation in the impeller 403. When the motor 2 stops using, the baffle 402 is pushed so that the bottom of the baffle 402 is embedded in the inside of the air intake pipe 404, and the inside of the tube body 401 is protected to prevent other objects from entering the inside of the tube body 401.
