[0020] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0021] The utility model discloses a car air conditioning maintenance device, combined with Figures 1 to 4 As shown, it includes an organic shell 1, in which a compressor 2, a condenser 3, a refrigerant tank 4, a vacuum pump 5 and an oil-gas separation mechanism 6 are arranged. The side of the shell 1 is provided with a first accommodating cavity 10 with an opening facing outward, and at least two refrigerated oil bottles 11 and at least one detection liquid bottle 12 are arranged in the first accommodating cavity 10. A bottle bracket 13 is fixed in the shell 1, and at least two refrigerated oil pipe heads 14 and at least one detection liquid pipe head 15 are provided on the bottle bracket 13. The refrigerated oil pipe heads 14 correspond one-to-one with the refrigerated oil bottles 11 and are plugged in, and the detection liquid pipe head 15 is plugged in with the detection liquid bottle 12.

[0022] In the above structure, the compressor 2, condenser 3, refrigerant tank 4, vacuum pump 5 and oil-gas separation mechanism 6 are all integrated in the casing 1, and the first accommodating cavity 10 is provided on the outer wall of the casing 1, and at least two refrigerated oil bottles 11 and at least one detection liquid bottle 12 are accommodated in the first accommodating cavity 10. Since the opening of the first accommodating cavity 10 faces outward, it is convenient to disassemble, assemble and replace the refrigerated oil bottles 11 and the detection liquid bottles 12. At the same time, at least two refrigerated oil pipe heads 14 and at least one detection liquid pipe head 15 are provided on the bottle bracket 13 in the casing 1, so that the two refrigerated oil pipe heads 14 are correspondingly plugged into the two refrigerated oil bottles 11, and the detection liquid pipe head 15 is plugged into and matched with the detection liquid bottle 12. Based on the above structure, automobile maintenance personnel can select corresponding refrigerated oil according to different types of vehicles, and at the same time, it is convenient to connect the detection liquid bottle 12 to realize leakage detection, which not only simplifies the number of equipment, but also helps maintenance personnel to operate, and better meets application requirements.

[0023] In order to make the outer surface of the housing 1 smooth, the embodiment preferably fixes the accommodating cavity inside the housing 1. For details, see Figure 1 and Figure 3 The first accommodating cavity 10 is recessed into the interior of the casing 1 , the bottle holder 13 is located above the first accommodating cavity 10 , and the refrigeration oil pipe head 14 and the detection liquid pipe head 15 both pass through the top wall of the first accommodating cavity 10 .

[0024] Regarding the specific number of refrigerated oil bottles and detection liquid bottles, in this embodiment, two refrigerated oil bottles 11 and one detection liquid bottle 12 are provided in the first accommodating cavity 10, and two refrigerated oil pipe heads 14 and one detection liquid pipe head 15 are provided on the bottle bracket 13.

[0025] The purpose of providing the detection liquid bottle in this embodiment is to realize the leakage detection function. Leakage detection is generally carried out after the vacuum operation. The internal pressure of the pipeline is detected by the pressure detection module. The presence of leakage is judged by observing whether the air pressure of the high-pressure gauge and the low-pressure gauge is stable. If it is unstable, it is determined that there is a leak. The maintenance personnel input the UV detection liquid in the detection liquid bottle into the pipeline and scan the vehicle air conditioning system with an ultraviolet leak detection lamp. The UV detection liquid will emit bright light and indicate the exact location of all leak points.

[0026] See Figure 4 In this embodiment, three first gravity sensors 16 are fixed to the bottle holder 13, and two refrigerated oil pipe heads 14 and one detection liquid pipe head 15 are respectively fixed to the sensing ends of the three first gravity sensors 16. Specifically, one end of the three first gravity sensors 16 is fixedly connected to the bottle holder 13, and the other ends of the three first gravity sensors 16 are respectively fixedly connected to the two refrigerated oil pipe heads 14 and one detection liquid pipe head 15. The device's pre-set tablet host 22 can determine the remaining oil and liquid in the two refrigerated oil bottles 11 and one detection liquid bottle 12 by collecting weight data fed back by the three first gravity sensors 16.

[0027] In order to facilitate the installation of two refrigeration oil pipe heads 14 and one detection liquid pipe head 15, in this embodiment, the sensing end of the first gravity sensor 16 is fixed with a first Z-shaped support plate 17, and the two refrigeration oil pipe heads 14 and one detection liquid pipe head 15 are respectively fixed on the three first Z-shaped support plates 17.

[0028] As a preferred embodiment, an inner flow channel support 18 is provided above the bottle holder 13, and three solenoid valves 180 are provided on the top of the inner flow channel support 18. The bottom of the inner flow channel support 18 is fixedly connected to the bottle holder 13 via a vertical rod 130. The three solenoid valves 180 are used to control the on / off of the refrigeration oil passage and the detection liquid.

[0029] In order to arrange the modules in the housing 1 in a reasonable manner, in this embodiment, Figures 1 to 4As shown, a front bracket 19 and a rear bracket 20 are fixed in the casing 1, the oil-gas separation mechanism 6 is fixed to the top of the front bracket 19, the compressor 2 is fixed to the bottom of the front bracket 19, the refrigerant tank 4 and the condenser 3 are both fixed to the bottom plate of the casing 1, the rear bracket 20 is fixed above the refrigerant tank 4, and the vacuum pump 5 is fixed to the top of the rear bracket 20. In this embodiment, the low-pressure pipeline inlet and the high-pressure pipeline inlet of the equipment are respectively connected to the refrigerant tank through two valve bodies. At the same time, the low-pressure pipeline inlet and the high-pressure pipeline inlet are respectively connected to the oil-gas separation mechanism through two other valve bodies. The oil-gas separation mechanism, the compressor, the condenser and the refrigerant tank are connected in sequence.

[0030] Further, combined with Figure 1 and Figure 4 As shown, the side of the casing 1 is provided with a second accommodating cavity 10 with an opening facing outward, and a recovery oil bottle 24 is provided in the second accommodating cavity 10. A second gravity sensor 25 is fixed on the front bracket 19, and a recovery pipe head 26 is fixed to the sensing end of the second gravity sensor 25. The recovery pipe head 26 is plugged into and matched with the recovery oil bottle 24.

[0031] Furthermore, a second Z-shaped support plate 27 is fixed to the sensing end of the second gravity sensor 25 , and the recovery pipe head 26 is fixed on the second Z-shaped support plate 27 .

[0032] In the above structure, this embodiment preferably uses a Z-shaped support plate to support and fix each tube head. Since the Z-shaped support plate is in an outward-extending shape, it can avoid positional interference between each tube head and the gravity sensor, thereby ensuring the accuracy of the weight data collected by the gravity sensor.

[0033] In order to facilitate human-computer interaction, in this embodiment, an oblique panel 21 is provided at the top of the housing 1 near the front side, and a tablet host 22 is embedded in the oblique panel 21 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
