Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile water pump with a detection function. Background Art

[0002] In the cylinder of a car engine, there is a water pump that can pump out the hot water in the water channel of the engine cylinder and then pump cold water in. There is also a thermostat next to the water pump. When the car is just started, it remains closed so that the cooling water circulates only in the engine. When the engine temperature rises above 95°, the thermostat opens and the hot water in the engine is pumped into the water tank. When the car moves forward, the cold wind blows through the water tank and takes away the heat.

[0003] After searching, the application with patent number CN202220643047.X discloses a high temperature resistant automobile water pump, including a water pump housing, a blocking mechanism is fixedly installed at the water outlet end of the water pump housing, one end of the blocking mechanism is fixedly connected with a detachable mounting head, one end of the blocking mechanism is provided with a blocking head located in the mounting head, and the diameter of the left port of the blocking head is smaller than the diameter of the right end thereof;

[0004] Although the high temperature resistant automobile water pump can reduce the accumulation of impurities in the water into the water pump housing through the installation head and the flow blocking mechanism, and is convenient for collecting and cleaning the impurities in the water, the high temperature resistant automobile water pump cannot detect in time whether the impurities in the water pump sedimentation tank need to be cleaned, and can only be discovered when the impurities hinder the water circulation inside the water pump, which poses a safety hazard.

[0005] Therefore, we propose an automobile water pump with detection function. Utility Model Content
