Embodiment 1

[0023] An electronic water pump capable of automatic gas detection and exhaust, as shown in the figure, includes a water pump body 1, the water pump body 1 is provided with a water inlet 101 and a water outlet 102, and the water outlet 102 is connected with a water outlet pipe 2, and the water outlet pipe 2 An exhaust chamber 3 communicating with the water outlet pipe 2 is arranged on the top, one end of the exhaust chamber is defined as its left end, the other end of the exhaust chamber 3 is defined as its right end, and the left end of the exhaust chamber 3 is provided with an outlet pipe 2 communicated with it. The air inlet 301, the side wall near the left end of the exhaust chamber 3 is also provided with an air outlet 302, the movable iron 4 that can move left and right is installed in the exhaust chamber 3, and the movable iron 4 moves in the exhaust chamber 3 and controls the air intake. The connection between the air port 301 and the air outlet 302 also includes a spri...

Embodiment 2

[0031] The difference from Embodiment 1 is that the water outlet pipe 2 includes a first pipe 21 and a second pipe 22, and also includes a water storage chamber 3, one end of the first pipe 21 communicates with the water outlet 102, and the other end of the first pipe 21 is formed by Insert the upper part of the water storage and gas collection chamber 23 from bottom to top, the exhaust chamber 3 is arranged on the second pipe 22, the lower end of the second pipe 22 is inserted into the bottom of the water storage and gas collection chamber 23 from top to bottom, and the water storage and gas collection chamber 23 A valve 231 is provided on the upper top surface of the valve, and the upper port of the first pipe 21 is higher than the lower port of the second pipe 22 .

[0032] Through the design of the water storage and gas collection chamber 3, the gas can be pre-excluded, and after being processed by the exhaust chamber 3, the gas can be discharged more accurately.

[0033] ...

Embodiment 3

[0035] The difference from Embodiment 2 is that it also includes a sealing plug 24 installed in the water storage and air collection chamber 23 and located below the second pipe 22, and also includes a sealing spring 241 fixed on the inner wall of the lower end of the water storage and air collection chamber 23, sealing The spring 241 is affixed to the lower surface of the sealing plug 24 , and the sealing plug 24 is lifted up by the action of the sealing spring 241 and seals the lower port of the second tube 22 .

[0036]The lower end of the second tube 22 is also sleeved with a telescopic tube 221 that can slide up and down along the second tube 22. The inside of the telescopic tube 221 is tightly bonded to the outer wall of the second tube 22. A buoyancy block 2211 is installed on the top of the telescopic tube 221. , the buoyancy block 2211 controls the expansion and contraction of the telescopic tube 221 through its own position in the water storage and air collection cham...

Abstract

The invention relates to the technical field of water pumps, and discloses an electronic water pump capable of automatically detecting air and exhausting air. The electronic water pump comprises a water pump body (1); an exhaust cavity (3) is connected to the water pump body (1); a movable iron (4) is arranged in the exhaust cavity (3); the electronic water pump further comprises a spring (5) arranged between the right end of the exhaust cavity (3) and the movable iron (4); and the exhaust cavity (3) is also provided with a solenoid valve coil (6). According to the electronic water pump, automatic air detection and automatic air exhaust can be realized without manual intervention; air can be automatically exhausted in real time, and thus the water pump is prevented from idling; the determination and realization of the anti-idling function of the water pump are facilitated; the filling and exhausting time of a water circulation cooling system or a thermal management system is fundamentally shortened, and the system maintenance cost is reduced; and an automatic air detection and automatic air exhaust control part is integrated into a built-in controller of the water pump, and the additional cost is negligible.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to an electronic water pump capable of automatic gas detection and exhaust. Background technique [0002] With the continuous development of automotive electronics and intelligence in recent years, especially the rising of new energy vehicles, electronic water pumps play an increasingly critical role in vehicle cooling systems, such as engine cooling, turbocharger cooling, drive Core components such as motors and their controllers, power battery cells or thermal management of fuel cell stack cores all need to use an intelligent water circulation cooling system composed of electronic water pumps. There has always been the problem of exhaust in the water circulation cooling system. Once the gas cannot be discharged in time, it will enter the cooling cycle process. In the mild case, the working efficiency of the system will be reduced, and in severe cases, the water pump will run d...
