Description

Technical Field

[0001] This utility model relates to the field of liquid storage dryer technology, specifically to an assembled automotive air conditioning liquid storage dryer. Background Technology

[0002] The liquid receiver-dryer is a component with a special function that has been continuously improved and updated in the development of air conditioning. Its main functions are "liquid storage" and "drying," as mentioned in its name, which is the "liquid receiver-dryer" involved in the refrigeration principle. The liquid receiver-dryer emerged with the development of modern refrigeration technology. In the refrigeration principle, the refrigerant undergoes physical transformations to achieve heat absorption and release. When the refrigerant is added to the sealed system of the air conditioner, moisture from the air and impurities from the pipes inevitably get mixed in. During the physical transformation process, the moisture will freeze into solid ice, clogging the sealed pipes of the air conditioning system, thus affecting the flow of refrigerant, ultimately leading to refrigeration failure, and in severe cases, explosion. The function of the liquid receiver-dryer is to absorb the moisture in the sealed air conditioning pipes and filter out the tiny impurities in the pipes.

[0003] Existing air conditioning liquid dryers on the market generally use a filter mechanism located between the intake and exhaust pipes to dry the gap between compressed gases. However, in actual use, the filter mechanism and the intake and exhaust pipes are integrated to avoid air leakage at the connection, but this makes it inconvenient to replace the filter structure and wastes a lot of resources. Therefore, we propose an assembled automotive air conditioning liquid dryer. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an assembled automotive air conditioning liquid receiver dryer, which solves the problem that in actual use, the filter mechanism, air outlet, and air intake pipe adopt an integrated structure to avoid air leakage at the connection, but it is inconvenient to replace the filter structure and wastes a lot of resources.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An assembled automotive air conditioning liquid receiver dryer includes a connecting ring. A first connecting pipe is provided on the top surface of the connecting ring, and a second connecting pipe is provided on the bottom surface of the connecting ring. A plurality of fixing blocks are fixedly installed on the outer wall surface of the connecting ring. The vertical fixing blocks form a group. A first fixing plate is fixedly installed on one side of the fixing block. A snap-fit ​​groove is opened on one side of the first fixing plate. The snap-fit ​​grooves on the group of fixing blocks are located on opposite sides. Two second fixing plates are fixedly installed on the outer wall surfaces of the first connecting pipe and the second connecting pipe. A snap-fit ​​block is fixedly installed on one side of the second fixing plate. The snap-fit ​​block is located on the side facing the connecting ring.

[0007] Preferably, the snap-fit ​​groove has two through holes inside, and two snap-fit ​​rods are fixedly installed on one side of the snap-fit ​​block. The snap-fit ​​rods are composed of a cylindrical part and a disc part.

[0008] Preferably, the top surface of the first connecting pipe has an air outlet pipe, which is connected to the interior of the first connecting pipe and has an L-shaped structure. The outer wall surface of the second connecting pipe has an air inlet pipe, which is connected to the interior of the second connecting pipe.

[0009] Preferably, the air outlet pipe and the air inlet pipe are internally fitted with a connecting sleeve, and a sealing ring is fixedly installed inside the connecting sleeve.

[0010] Preferably, both the first connecting pipe and the second connecting pipe are composed of a cylindrical pipe portion and a circular ring portion. Both the first connecting pipe and the second connecting pipe are snapped together with the connecting ring through the circular ring portion, and a contact sleeve is fixedly installed inside the connecting ring.

[0011] Preferably, the connecting ring is fitted with filter cotton inside the contact sleeve, and the filter cotton is fitted with a filter element inside the filter cotton.

[0012] In summary, the present invention has the following main advantages:

[0013] 1. By setting a snap-fit ​​groove, and through the design of the snap-fit ​​groove and snap-fit ​​block, the positional relationship between the connecting ring, the first connecting pipe and the second connecting pipe can be defined by snap-fit, which makes it convenient to disassemble and install the whole at any time. In case of problems, the connecting ring can be directly replaced, which not only makes the use of the device more convenient, but also reduces unnecessary losses.

[0014] 2. By setting through holes, the design of through holes and snap-fit ​​rods can help strengthen the fixing relationship between the connecting ring, the first connecting pipe and the second connecting pipe through the snap-fit ​​groove and snap-fit ​​block, and further increase the overall stability of the device when subjected to external forces.
