Description

Technical Field

[0001] The utility model relates to the technical field of filling devices, in particular to an automatic refrigerant filling device. Background Art

[0002] Air conditioning refrigerant, commonly known as refrigerant, is a working fluid used to transfer heat energy and produce a freezing effect in a refrigeration and air conditioning system. It can be divided into primary refrigerant and secondary refrigerant according to its working method, and can be divided into natural refrigerant and synthetic refrigerant according to its material properties. Refrigerant is used to transfer heat energy and produce a freezing effect in a refrigeration and air conditioning system. Freon is the commonly used refrigerant for air conditioning.

[0003] In the process of filling the existing air-conditioning refrigerant, a fluorine bottle is needed. During the filling process, the fluorine inlet of the air-conditioning is opened, and then the fluorine bottle discharge pipe is connected to the fluorine inlet, and then the fluorine bottle is turned upside down to start exhausting, and then the valve is opened to deliver fluorine. During the fluorine delivery process, the pressure gauge needs to be checked at all times to avoid excessive fluorine waste. After the fluorine flushing is completed, the fluorine bottle needs to be put back to its original state and then the valve is closed. The whole process needs to be completed by the staff alone, which is rather troublesome. However, the existing fluorine bottle does not have a convenient and overturnable structure. In order to optimize the use of the existing air-conditioning refrigerant filling device, we propose an automatic refrigerant filling device. Utility Model Content

[0004] In view of the above problems, the utility model provides a refrigerant automatic filling device, which has the effect of improving the filling convenience.

[0005] The technical solution of the utility model is:

[0006] A refrigerant automatic filling device comprises a fluorine bottle, a valve body is provided at the top of the fluorine bottle, and a filling tube is provided on the surface of the valve body, a support frame is provided on the outside of the fluorine bottle, protrusions are fixedly installed on both side walls of the fluorine bottle, a support rod extending toward the support frame is fixedly installed on the surface of the protrusion, and a rotating shaft is inserted into the surface of the support frame, and one end of the support rod away from the fluorine bottle is located on the inner wall of the rotating shaft, one end face of one of the support rods passes through the rotating shaft and is connected to a first bevel gear, the bottom surface of the first bevel gear is meshed with a second bevel gear, and the bottom surface of the second bevel gear is fixedly connected to a connecting rod, a servo motor is provided on one side wall of the support frame, and the bottom end of the connecting rod rotates with the output end of the servo motor, and a switch button is provided on the surface of the servo motor.

[0007] In a further technical solution, the support frame includes side panels and a support frame. Side panels are provided on both sides of the fluorine bottle. Support frames are fixedly installed at the upper and lower ends of the opposite surfaces of the two side panels. The support frame is square, and the rotating shaft is installed on the surface of the side panels.

[0008] In a further technical solution, a metal shell is fixedly mounted on the side wall of one of the side panels, and the outer surface of the servo motor is inserted into the inner wall of the metal shell.

[0009] In a further technical solution, four fixed pulleys are fixedly mounted on the bottom surface of the support frame located at the bottom, and a handle is fixedly mounted on the top of one side of the side plate close to the metal shell.

[0010] In a further technical solution, the side panels, support frame and handles are all made of aluminum alloy.

[0011] The beneficial effects of the utility model are:

[0012] By providing the support frame and the protrusions and support rods on both side walls of the fluorine bottle, the fluorine bottle can be rotatably connected to the support frame. When the fluorine bottle needs to be turned over and filled with fluorine, the servo motor is driven to engage the first bevel gear and the second bevel gear, so that the support rod is rotated to turn the fluorine bottle. After the overall flip, the drive of the servo motor is stopped, and the tooth groove clamping state of the first bevel gear and the second bevel gear can be used to maintain the inverted stability of the fluorine bottle. When the valve body needs to be closed, the servo motor can be directly driven to turn the fluorine bottle back, and then the valve can be closed quickly and manually, which reduces physical exertion of personnel and improves the convenience of filling work.

[0018] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] Example:

[0020] like Figure 1-Figure 3As shown, a refrigerant automatic filling device includes a fluorine bottle 1, a valve body is provided at the top of the fluorine bottle 1, and a filling tube is provided on the surface of the valve body, side plates 11 are provided on both sides of the fluorine bottle 1, and support frames 12 are fixedly installed at the upper and lower ends of the opposite surfaces of the two side plates 11, and the support frame 12 is square, and protrusions 2 are fixedly installed on the two side walls of the fluorine bottle 1, and support rods 3 are fixedly installed on the surface of the protrusions 2. A rotating shaft 4 is inserted on the surface of the side plate 11, and the end of the support rod 3 away from the fluorine bottle 1 is located on the inner wall of the rotating shaft 4. By arranging the side plates 11 and the support frames 12, the surface of the support frame can have an empty groove formed by the side plates 11, which is convenient for the fluorine bottle 1 to flip over and has the stability of supporting the fluorine bottle 1. The end face of one of the support rods 3 passes through the rotating shaft 4 and is connected to the first bevel gear 5. The first bevel gear A second bevel gear 6 is meshed on the bottom surface of the wheel 5, and a connecting rod 8 is fixedly connected to the bottom surface of the second bevel gear 6. A servo motor 7 is provided on one side wall of the support frame. The bottom end of the connecting rod 8 rotates with the output end of the servo motor 7. A switch button 9 is provided on the surface of the servo motor 7. A metal shell 10 is fixedly installed on the side wall of one side panel 11, and the outer surface of the servo motor 7 is inserted into the inner wall of the metal shell 10. Four fixed pulleys 13 are fixedly installed on the bottom surface of the support frame 12 below. A handle 14 is fixedly installed on the top of one side of the side panel 11 close to the metal shell 10 to facilitate moving the whole device and improve the convenience of use of the device. The side panel 11, the support frame 12 and the handle 14 are all made of aluminum alloy, which makes the device relatively light and easy to lift, while having support stability.

[0021] The working principle of the above technical solution is as follows:

[0022] When filling is required, the flushing main pipe on the surface of the fluorine bottle 1 is connected to the fluorine inlet pipe of the air conditioner, and then the valve body is opened to discharge the gas, and then the servo motor 7 is driven to rotate the connecting rod 8 to rotate the second bevel gear 6 and the first bevel gear 5 to engage and rotate. During the process, the fluorine bottle 1 has the effect of being relatively supported and flipped by the two support rods 3. When the fluorine bottle 1 is in an inverted state, the servo motor 7 is stopped and braked, and then the fluorine bottle 1 maintains stability after the first bevel gear 5 and the second bevel gear 6 stop engaging. After the filling is completed, the servo motor 7 can be directly operated to reverse again to reset the fluorine bottle 1.

[0023] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
