Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the lancet is installed in the connector movably. After the connector is connected to the gas tank, the handle of the lancet is twisted to stab the lancet towards the gas tank. After piercing the cover of the gas tank, it is necessary to rotate the handle , make it out of the gas tank, inconvenient to use

Embodiment 1

[0027] Embodiment 1: a kind of automobile air conditioner refrigerant adding opener, such as figure 1 with figure 2 As shown, the opener main body 1 including the opener, the transmission shaft 2 arranged in the opener main body 1 and the refrigerant bottle 3 connected to one end of the opener main body 1; the refrigerant bottle 3 is filled with refrigerant; the transmission shaft 2 is provided with The channel 21 for refrigerant to pass through, the end of the opener body 1 far away from the refrigerant bottle 3 is set as the first interface 11 for communicating with the interface of the automobile air conditioner. The other end is set as the second interface 12, and the two ends of the channel 21 communicate with the first interface 11 and the second interface 12 respectively, and the control valve 4 for controlling the opening and closing of the second interface 12 is provided in the opener main body 1; One end of the transmission shaft 2 extends to the first interface 11...

Embodiment 2

[0038] Embodiment two: a kind of automobile air conditioner refrigerant adding opener, such as image 3 As shown, the difference from the first embodiment is that the transmission shaft 3 partially extends out of the first interface 11. When the transmission shaft 3 partially extends out of the first interface 11, in this specific embodiment, the upper transmission shaft 2 of the opener extends One end is inserted into the interface of the automobile air conditioner to realize the purpose of triggering the pressure opening needle 22 during the connection between the first interface 11 and the interface of the automobile air conditioner. The appropriate implementation mode can be selected according to the actual working conditions, which increases the scope of application of the opener. .

Abstract

The invention provides an automobile air conditioner refrigerant adding opener and relates to the field of automobile maintaining devices. The automobile air conditioner refrigerant adding opener comprises an opener body of the opener, a transmission shaft arranged in the opener body and a refrigerant bottle connected to one end of the opener body. The transmission shaft is internally provided with a channel for refrigerant in the refrigerant bottle to pass through. The end, far away from the refrigerant bottle, of the opener body is set as a first connector used for communicating with an automobile air conditioner connector, and the other end of the opener body is set as a second connector. The two ends of the channel communicate with the first connector and the second connector correspondingly. The opener body is internally provided with a control valve controlling the second connector to open and close. One end of the transmission shaft extends to the first connector, and the otherend of the transmission shaft makes contact with the control valve. A pressure opening needle is arranged at the position, corresponding to the transmission shaft, of the first connector. When the automobile air conditioner connector is connected with the first connector and triggers the pressure opening needle, and the control valve is opened. The automobile air conditioner refrigerant adding opener has the advantages that integration of the opener is achieved, and the opener is convenient to use.

Description

technical field [0001] The invention relates to the field of automobile maintenance equipment, in particular to an automobile air-conditioning refrigerant adding device. Background technique [0002] Automobile air-conditioning system is an important part of the driver's comfort, especially in hot summer, but with the long-term operation of the air-conditioning system, the refrigerant content will decrease, resulting in a decline in the cooling effect of the air-conditioning, usually people A visit to a car-specific service shop is required to add the refrigerant, which is time-consuming and labor-intensive. Therefore, correspondingly produced the refrigerant of portable air tank, thereby driver can directly add refrigerant to air-conditioning system by oneself. [0003] The traditional refrigerant addition tool uses a puncture needle to pierce the seal of the gas tank mouth of the gas tank, allowing the refrigerant to flow out of the gas tank and then into the automotive a...
