Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary water pumps, in particular to an auxiliary water pump for an automobile. Background Art

[0002] The automobile auxiliary water pump is a device that provides auxiliary cooling for the engine in the automobile cooling system. It is an important component of the automobile cooling system and plays an irreplaceable role in the maintenance and repair of the automobile cooling system.

[0003] For example, the Chinese patent with publication number CN210829462U discloses an auxiliary electronic water pump for automobiles, including a pump body, a shell, a first bolt, a rotating shaft, a rotor, a rotor slot, a stator, an epoxy resin gasket, a support frame, a cavity, a controller, a second bolt, a support buckle, a terminal female plug, a bottom cover, a plug, a wiring terminal, a reinforcing rib vertical plate, a water inlet interface, a water outlet interface and a fixing rod. The top outer wall of the pump body is snap-connected with the shell, and the inner wall of the pump body on both sides of the shell is threadedly connected with the first bolt, and the other end of the first bolt is inserted into the interior of the shell. The auxiliary electronic water pump adopts an epoxy resin gasket. Since epoxy resin has the characteristics of water resistance, good leakage resistance, high strength and strong adhesion, it can ensure that the stator will not loosen when the environment is relatively harsh and the vibration is relatively large, and there will be no coolant leakage, thereby ensuring the life of the water pump. This product has the advantages of stable flow and pressure, long service life and low noise.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the device is connected to the pipeline, it needs to be fixed with multiple accessories and tools, which is complicated and time-consuming. At the same time, since the device lacks a built-in filtering system, water may carry impurities when flowing through the device, causing blockage, thereby shortening the service life of the device. In view of this, we propose an auxiliary water pump for automobiles. Utility Model Content

[0013] In the technical solution, when it is necessary to connect the water inlet pipe to one of the pipes, a driving assembly is provided, and then under the action of the tension of the two tension springs, the two limit blocks slide in the direction of the two tension springs respectively, and then one of the pipes is inserted into the water inlet pipe. When the two rectangular grooves are respectively connected to the two sliding grooves, the two limit blocks can be driven to slide by the provided driving assembly, and at the same time, the two tension springs are stretched by the pulling. When one end of the two limit blocks is respectively inserted into the corresponding two rectangular grooves, the position of one of the pipes can be fixed, so that the water inlet pipe and the water outlet pipe can be connected to the two pipes respectively, and the operation is simple.

[0014] When one of the filters needs to be replaced, first reverse the operation and take out one of the pipes. Then the person pulls the pull rod and drives one of the rings to move. Then the ring can be taken out from the water inlet pipe or the water outlet pipe. When a new ring needs to be installed, first insert the ring into the water inlet pipe or the water outlet pipe. The position of the ring can be limited by the set limit assembly. At the same time, one of the pipes will squeeze the ring to further limit the position of the ring, which is convenient for installation and disassembly of the filter.
