[0002] An air conditioner, i.e., an air conditioner, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in a building or structure. Generally, it includes a cold source / heat source device, a cold and hot medium distribution system, an end device, and several other auxiliary devices. The leak-proof liquid filling device is a device used for gas and liquid filling during air conditioner maintenance.
[0003] When filling the refrigerant, generally, the refrigerant bottle is connected to the low-pressure filling port of the outdoor unit of the air conditioner on-site to achieve filling. However, the capacity of the refrigerant bottle is limited, and generally, multiple bottles of refrigerant are required to meet the demand. The maintenance personnel need to disassemble the refrigerant bottle and replace it with a new one for connection and filling. Therefore, the on-site operation is relatively troublesome, affecting the maintenance efficiency.
[0004] Therefore, a leak-proof liquid filling device for air conditioner maintenance is proposed. Content of the Utility Model

[0023] As Figures 1 to 4 shown, a leak-proof liquid filling device for air conditioner maintenance includes a mounting plate 1. A clamping assembly 2 for limiting the refrigerant bottle is provided on the surface of the mounting plate 1. A fixing frame 3 is fixedly connected to the surface of the mounting plate 1. A filling mechanism 4 for connecting the refrigerant bottle and the air conditioner is provided on the surface of the fixing frame 3. More specifically, before maintenance, a plurality of refrigerant bottles are placed on the top surface of the mounting plate 1 and clamped and fixed by the clamping assembly 2. The filling mechanism 4 is connected to the refrigerant bottle. After reaching near the outdoor unit of the air conditioner, the filling mechanism 4 is connected to the filling port of the outdoor unit of the air conditioner. The refrigerant can be introduced into the outdoor unit of the air conditioner by using the filling mechanism 4 to achieve refrigerant filling, and the refrigerant bottle can be switched at any time for filling. The effect of facilitating the rapid refrigerant filling of the air conditioner is achieved during use. A large amount of preparatory work can be completed before the maintenance work. During on-site operation, only the outdoor unit filling port and the switch valve need to be connected, effectively improving the maintenance efficiency.
[0024] The clamping assembly 2 includes a lead screw 201, and the lead screw 201 is rotatably connected to the inner wall of the mounting plate 1. A knob 202 is fixedly connected to the right end of the lead screw 201. A support rod 203 is threadedly connected to the surface of the lead screw 201. A chute 204 is formed through the top surface of the mounting plate 1, and the inner wall of the chute 204 is slidably connected to the support rod 203. The top end of the support rod 203 is fixedly connected to a movable plate 205, and a fixed plate 206 is fixedly connected to the top surface of the mounting plate 1. It should be noted that the refrigerant bottle filled with the refrigerant medium is placed between the fixed plate 206 and the movable plate 205. By rotating the knob 202, the lead screw 201 is driven to rotate. Under the action of the thread, the support rod 203 will be driven to slide along the inner wall of the chute 204, thereby driving the movable plate 205 to move. By jointly cooperating with the movable plate 205 and the fixed plate 206, the refrigerant bottle is clamped and fixed.
[0025] Anti-slip pads 5 are fixedly connected to the opposite surfaces of the movable plate 205 and the fixed plate 206, and the anti-slip pads 5 are made of rubber. More specifically, by providing the anti-slip pads 5 made of rubber, the friction with the surface of the refrigerant bottle is increased, making the clamping more stable.
[0026] The filling mechanism 4 includes a plurality of fixed pipes 401, and the fixed pipes 401 are fixedly inserted into the fixed frame 3. A collecting pipe 402 is fixedly connected to the left end of the fixed pipe 401. A connecting hose 403 is fixedly connected to the surface of the collecting pipe 402. A filling head 404 is fixedly connected to the end of the connecting hose 403. The filling mechanism 4 further includes a docking assembly for connecting with the refrigerant bottle. It should be noted that through the docking assembly, it is connected to the refrigerant bottle, and the filling head 404 is connected to the low-pressure filling port of the air conditioner outdoor unit. The refrigerant medium can enter the collecting pipe 402 through the fixed pipe 401, and the refrigerant is sent into the outdoor unit filling port through the connecting hose 403 and the filling head 404 to realize the filling operation. In specific implementation, a pressure gauge can be provided in the middle section of the connecting hose 403 to ensure that the filling pressure meets the standard.
[0027] The docking assembly includes an internally threaded swivel joint 406, and the internally threaded swivel joint 406 is slidably sleeved on the right end of the fixed pipe 401. A control valve 405 is provided on the surface of the fixed pipe 401. A sealing gasket 407 is fixedly connected to the right end of the internally threaded swivel joint 406. More specifically, it is connected to the threaded interface on the surface of the refrigerant bottle through the internally threaded swivel joint 406, and the interface is pressed tightly by the sealing gasket 407 to avoid leakage and achieve the anti-leakage effect. Since the fixed pipe 401 and the internally threaded swivel joint 406 can slide relative to each other, the distance between the fixed pipe 401 and the refrigerant bottle interface can be sealed. By opening the control valve 405, the medium in the refrigerant bottle can be exported.
[0028] Magnet sheets 6 are fixedly connected to both the front side and the rear side of the bottom surface of the mounting plate 1. More specifically, many air conditioner outdoor units are made of iron. Adsorbing the air conditioner outdoor unit with the magnet sheets 6 can make the mounting plate 1 placed more stably.
[0029] In summary: Before maintenance, place multiple refrigerant bottles on the top surface of the mounting plate 1, clamp and fix them through the clamping assembly 2, connect the filling mechanism 4 to the refrigerant bottles. After reaching near the air conditioner outdoor unit, connect the filling mechanism 4 to the filling port of the air conditioner outdoor unit. The refrigerant can be introduced into the air conditioner outdoor unit by using the filling mechanism 4 to achieve refrigerant filling, and the refrigerant bottles can be switched at any time for filling. The effect of facilitating the rapid refrigerant filling of the air conditioner is achieved during use. A large amount of preparatory work can be completed before the maintenance work is carried out. During on-site operation, only the outdoor unit filling port and the switch valve need to be connected, effectively improving the maintenance efficiency.
