Technical Field

[0001] This utility model belongs to the technical field of filling equipment, specifically relating to an antifreeze filling device. Background Technology

[0002] Antifreeze is a special liquid used to prevent freezing and engine overheating, while antifreeze filling equipment is a device specifically designed to quickly and accurately add antifreeze to the car's cooling system, ensuring that the car engine can operate stably in various environments;

[0003] In the prior art, Chinese patent with publication number CN222524184U discloses an antifreeze filling device. This prior art uses a valve structure to prevent antifreeze from flowing out at will, but this structure is not convenient for adding antifreeze and is inconvenient to use. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an antifreeze filling device. This antifreeze filling device is equipped with a one-way valve that can change direction, thereby facilitating the addition and filling of antifreeze in the tank and making it more convenient to use.

[0005] The technical solution adopted by this antifreeze filling device to solve its technical problem is as follows:

[0006] An antifreeze filling device is provided, including a tank, a piston plate that slides and cooperates with the tank, a moving device that drives the piston plate to move up and down on the top of the tank, the bottom of the tank being fixedly connected to the upper end of a first pipe and communicating with it, the lower end of the first pipe being provided with a normally closed connector, a connecting pipe being provided below the tank, both ends of the connecting pipe being fixedly installed with normally open connectors, and a one-way valve being provided on the connecting pipe.

[0007] Furthermore, the moving device includes a moving motor and a screw. The moving motor is fixedly installed on the top surface of the tank. The output shaft of the moving motor passes through the tank and is rotatably connected. The upper end of the screw is fixedly connected to the output shaft of the moving motor. The screw passes through the piston plate and is threaded. The screw passes through the eccentric part of the piston plate. A vent hole is provided on the top surface of the tank.

[0008] Furthermore, the moving motor is a servo motor.

[0009] Furthermore, an insertion tube is provided below the connecting tube, and a connecting connector is provided at the upper end of the insertion tube.

[0010] Furthermore, a movable handle is fixedly installed on the outer periphery of the tank.

[0011] Furthermore, an anti-slip sleeve is fixedly installed on the outer periphery of the movable handle.

[0012] Furthermore, a heat dissipation shield is provided on the top of the tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model provides an antifreeze filling device that connects to a normally closed connector via a normally open connector. By selecting the normally open structure, the flow direction of the one-way valve can be controlled. When antifreeze needs to be added, the antifreeze flows from top to bottom through the one-way valve. A moving device drives the piston plate downward, discharging the antifreeze from the tank. When antifreeze needs to be added to the tank, the normally open connector connected to the normally closed connector is changed, and the moving device drives the piston plate upward, drawing the antifreeze into the tank. Compared with the prior art, this utility model is equipped with a one-way valve that can change direction, thus facilitating the addition and filling of antifreeze into the tank and making it more convenient to use.

[0015] 2. An antifreeze filling device according to this utility model embodiment, when the moving motor is turned on, the output shaft of the moving motor can drive the screw to rotate, and the rotation of the screw can drive the piston plate to move up and down. The moving device has a simple structure and is easy to use.

[0016] 3. The antifreeze filling device of this utility model, compared with other types of motors, has more precise position control, makes it easier to control the amount of antifreeze added, and is more convenient to use.

[0017] 4. An antifreeze filling device according to this utility model allows for easy filling or adding of antifreeze via a tube.

[0018] 5. An example of this utility model is an antifreeze filling device, in which a movable handle provides a point of leverage for the user, making it easy for the user to move this utility model.

[0019] 6. In an example of this utility model, an antifreeze filling device has an anti-slip sleeve that increases the friction between the user's hand and the moving handle, thereby reducing hand slippage.

[0020] 7. In an example of this utility model, an antifreeze filling device has a heat dissipation cover that can prevent the moving motor from slipping. Attached Figure Description

When antifreeze needs to be added, the antifreeze can flow from top to bottom through the one-way valve. The piston plate 2 is moved downward by the moving device, which can discharge the antifreeze from the tank 1. When antifreeze needs to be added to the tank 1, the normally open connector 6 connected to the normally closed connector 4 is changed.

When the moving motor 7 is turned on, the output shaft of the moving motor 7 can drive the screw 8 to rotate. The rotation of the screw 8 can drive the piston plate 2 to move up and down. This moving device has a simple structure and is easy to use.

[0028] like Figure 1 As shown, in a further preferred embodiment, the moving motor 7 is a servo motor, and a servo controller is installed on the tank 1 and electrically connected to the moving motor 7. Compared with other types of motors, servo motors offer more precise position control, make it easier to control the amount of antifreeze added, and are more convenient to use.
