DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 As shown, an assembled automobile air-conditioning liquid storage dryer according to an embodiment of the utility model includes a dryer cylinder 1 and a plug 2. An assembly port 10 for installing the plug 2 is formed at one end of the dryer cylinder 1. The plug 2 includes an assembly portion 20 adapted to the assembly port 10 and a filter portion 3 located at the inner end of the assembly portion 20. The filter portion 3 includes a shell 30 and the shell 30 is formed with a receiving interval 31. The receiving interval 31 has a filter element 32 built therein and the filter element 32 is detachably connected to the receiving interval 31 through a clamping assembly.

[0021] When in use, the plug 2 is installed and fixed in the assembly port 10. The filter part 3 at the inner end of the plug 2 is located in the dryer cylinder 1 when the plug 2 is installed. The filter part 3 is used to filter the medium entering the dryer cylinder 1 to prevent impurities in the air-conditioning system from entering the system and causing system blockage and failure. The filter element 32 is detachably arranged in the accommodating interval 31 through a clamping assembly. When the filter element 32 is damaged, the filter element 32 can be replaced separately, which is convenient for daily maintenance and replacement of the filter element 32, while reducing the daily use and maintenance costs of the product.

[0022] The filter element 32 includes a mounting seat 33 , a filter cartridge 34 and filter cotton 35 . A medium channel 36 is formed at the center of the mounting seat 33 and a mounting step surface 37 is formed at the inner end. The filter cartridge 34 is threadedly connected to the mounting step surface 37 , and the filter cotton 35 is placed in the filter cartridge 34 .

[0023] When in use, the filter cartridge 34 is fixedly connected to the mounting seat 33 through a threaded connection with the mounting step surface 37. When the filter cartridge 34 is installed, the filter cotton 35 is confined in the filter cartridge 34. When in use, the filter cotton 35 can be replaced by simply removing the filter cartridge 34.

[0024] A plurality of first through windows 4 are equidistantly and spaced apart on the outer circumference of the filter cartridge 34 , and a second through window 40 is provided at each first through window 4 of the shell 30 . A boss portion 41 is formed at the center of the inner bottom surface of the filter cartridge 34 , and an annular portion 42 extends from the inner opening end of the medium channel 36 . The boss portion 41 and the annular portion 42 cooperate to position the filter element 32 .

[0025] When in use, the external medium enters the filter cartridge 34 through the first through window 4 and the second through window 40, and then is filtered by the filter cotton 35, and the filtered medium is discharged through the medium channel 36;

[0026] The filter cotton 35 is positioned by the boss portion 41 and the annular matching portion 53 to prevent the filter cotton 35 from being incorrectly displaced in the filter cartridge 34 and affecting its filtering effect on the medium.

[0027] The mounting seat 33 is located on both sides of the outer open end of the medium channel 36, and two accommodating cavities 5 are correspondingly formed thereon. A shift block 50 is arranged inside the accommodating cavity 5, and a clamping portion 51 is formed on the outer end of the shift block 50. The upper open end of the accommodating interval 31 is adapted to the mounting seat 33 and is provided with a pair of clamping grooves 52 respectively matched with the pair of clamping portions 51; a mating portion 53 is formed at one end of the shift block 50 located in the accommodating cavity 5, and a spring member 54 is sleeved on the outer ring of the mating portion 53, and a limiting protrusion 55 matched with the spring member 54 is formed inside the accommodating cavity; through openings 56 are opened at the outer side surface of the mounting seat 33 corresponding to each accommodating cavity 5, and the shift block 50 has a shifting portion 57 extending out of the through opening 56.

[0028] When the filter element 32 needs to be maintained or replaced during use, the force is applied to the shifting parts 57 of the two shifting blocks 50 to move the two shifting blocks 50 toward each other, so that the clamping parts 51 at the outer ends of the two shifting blocks 50 are withdrawn from the corresponding clamping grooves 52. At this time, the filter element 32 can be removed for maintenance or replacement.

[0029] The two toggle parts 57 move in opposite directions while causing the spring member 54 to be compressed and in an energy storage state. When the filter element 32 needs to be installed, the filter element 32 only needs to be pushed into the receiving recess again and the interference force on the two toggle parts 57 is cancelled. At this time, the two toggle blocks 50 return to the initial position due to the release of the energy stored in the spring member 54 and enter the corresponding clamping groove 52 again, thus completing the installation and fixation of the filter element 32.

[0030] The inner circumferential surface of the assembly opening 10 has an internal thread 11 , and the assembly portion 20 has an external thread 21 matched with the internal thread 11 .

[0031] When in use, the plug 2 is installed and fixed to the dryer cylinder 1 through the threaded connection between the assembly port 10 and the assembly portion 20, which ensures the stability of the connection and facilitates daily maintenance and disassembly.

[0032] The outer surface of the dryer cylinder 1 is provided with a connecting pipe 12 at a position corresponding to the filter element 32 , and the inner circumferential surface of the dryer cylinder 1 is provided with a retaining ring portion 13 that cooperates with the filter element 32 .

[0033] When in use, external media enters the dryer cylinder 1 through the connecting pipe 12. The filter element 32 is installed and abuts against the abutting ring 13 to form a filtering zone. The media entering the dryer cylinder 1 through the connecting pipe 12 enters the filter element 32 through the filtering zone and is filtered before it can continue to be transported along the dryer cylinder 1.

[0034] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
