Detailed Embodiment

[0026] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] As Figures 1-5As shown in the figure, the present utility model provides a technical solution: a gas-liquid separation structure inside an air-conditioning liquid receiver, which includes a cylinder body 1, a liquid outlet pipe 2 connected to the bottom of the cylinder body 1, a liquid inlet pipe 4 arranged at the upper part of the cylinder body 1, a gas outlet pipe 5 connected to the upper part of the cylinder body 1, and a connection component 3 arranged inside the cylinder body 1. The connection component 3 includes a filtering mechanism 31 arranged inside the cylinder body 1, and an auxiliary mechanism 32 arranged at the upper part of the cylinder body 1. The filtering mechanism 31 includes a bearing ring 311 fixedly connected to the inner wall of the liquid inlet pipe 4. A sealing ring 312 is fixedly connected to the bottom of the bearing ring 311. An installation ring 313 is slidably connected to the inner wall of the liquid inlet pipe 4. A first filter plate 314, a second filter plate 315, and a third filter plate 316 are respectively fixedly connected to the inner wall of the installation ring 313. A positioning block 317 is fixedly connected to the outer wall of the installation ring 313. One end of a limiting rod 318 is rotatably connected to the bottom of the liquid inlet pipe 4 through a bearing. One end of the limiting rod 318 is movably connected to a clamping rod 319. The bottom end of the clamping rod 319 is fixedly connected to a limiting block 3110. A first spring 3111 is fixedly connected to the upper part of the limiting block 3110. A clamping groove 3112 is formed at the bottom of the liquid inlet pipe 4. A positioning groove 3113 is formed on the inner wall of the bottom of the liquid inlet pipe 4. An inner groove 3114 is formed on the inner wall of the positioning groove 3113. A top-out column 3115 is sleeved inside the inner groove 3114. A second spring 3116 is fixedly connected to the inner wall of the inner groove 3114.

[0029] In this embodiment, the positioning block 317 is clamped with the positioning groove 3113. One end of the first spring 3111 away from the limiting block 3110 is fixedly connected to the limiting rod 318. The inner side of the limiting rod 318 is attached to the bottom of the positioning block 317. The clamping rod 319 is clamped with the clamping groove 3112. Through the cooperation of the installation ring 313, the first filter plate 314, the second filter plate 315, and the third filter plate 316, the refrigerant can be filtered in multiple stages, so that the filtering effect can be better, and it is more convenient for subsequent use. At the same time, through the cooperation of the positioning groove 3113, the positioning block 317, the limiting rod 318, the clamping rod 319, the limiting block 3110, the first spring 3111, and the clamping groove 3112, it is convenient for manual disassembly of the installation ring 313, so that it is convenient for manual cleaning or direct replacement of the first filter plate 314, the second filter plate 315, and the third filter plate 316, so as to achieve a better filtering effect on the refrigerant.

[0030] Furthermore, one end of the second spring 3116 is fixedly connected to the top-out column 3115. Through the cooperation of the second spring 3116 and the top-out column 3115, when the limiting rod 318 is away from the bottom of the positioning block 317, the installation ring 313 can be ejected outward, which is more convenient for manual removal of the installation ring 313.

[0031] Even further, the number of the limiting rods 318 is two, which are symmetrically distributed at the bottom of the liquid inlet pipe 4.

[0032] When the device is in use, after the refrigerant enters the cylinder body 1 through the liquid inlet pipe 4, the liquid will precipitate at the bottom of the inner wall of the cylinder body 1, while the gas will move upward and then enter the gas outlet pipe 5, so as to achieve the effect of gas-liquid separation. And under the action of the mounting ring 313, the first filter plate 314, the second filter plate 315, and the third filter plate 316, the refrigerant can be filtered in multiple stages, so that the filtering effect is better, and it is more convenient for subsequent use. When it is necessary to disassemble the mounting ring 313, first manually disassemble the liquid inlet pipe 4, and then manually pull down the clamping rod 319 to separate the clamping rod 319 from the clamping groove 3112. Then manually rotate the limiting rod 318 to make the limiting rod 318 away from the bottom of the positioning block 317. Subsequently, under the action of the elastic force of the second spring 3116, the ejecting column 3115 can press the positioning block 317 outward. And since the positioning block 317 is fixedly connected to the mounting ring 313, the mounting ring 313 can be ejected outward. Then the mounting ring 313 can be taken out manually, so as to facilitate manual cleaning or direct replacement of the first filter plate 314, the second filter plate 315, and the third filter plate 316, and thus a better filtering effect on the refrigerant can be achieved.

The inner wall of the sealing sleeve 323 is provided with an internal thread 324. The outer wall of the sealing sleeve 323 is fixedly connected with an anti-slip block 325.

[0035] In this embodiment, the sealing sleeve 323 is threadedly connected to the outer wall of the fixing ring 321 through the internal thread 324. Through the cooperation of the fixing ring 321, the external thread 322, the sealing sleeve 323, the internal thread 324, and the anti-slip block 325, it is convenient for manual disassembly and assembly operations of the liquid inlet pipe 4, and thus it is convenient for manual subsequent disassembly and assembly operations of the mounting ring 313.

[0036] When it is necessary to disassemble the liquid inlet pipe 4, only need to manually rotate the sealing sleeve 323 counterclockwise. Under the action of the internal thread 324 and the external thread 322, the sealing sleeve 323 can move upward. And since the sealing sleeve 323 is fixedly connected to the liquid inlet pipe 4, the liquid inlet pipe 4 can move upward synchronously. Then the liquid inlet pipe 4 can be taken out manually.
