Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration compressor accessories, specifically relating to an improved cover structure for a refrigeration compressor intake muffler. Background Technology

[0002] Figure 3 The diagram shows the cover structure of a refrigeration compressor suction muffler in the prior art, including a cover 1. In use, the cover 1 is fixed to the housing 2 of the refrigeration compressor suction muffler. An air inlet 12 extends from the left side of the cover 1, communicating with the cover cavity 11. An air outlet 13, also communicating with the cover cavity 11, extends upward from the top of the cover 1. In this structure, the cover 1 and the upper part of the housing 2 form a non-removable integral unit, specifically constructed using high-frequency welding. However, due to the connection with the end of the aforementioned air inlet 12... Figure 3 A rubber sleeve 3 needs to be connected to the left end port shown. Since the material of the rubber sleeve 3 is very different from that of the cover 1, that is, the rubber sleeve 3 is rubber while the cover 1 is plastic, the rubber sleeve 3 cannot be connected to the air inlet 12 by high frequency welding. Therefore, a clamp 4 is often used to fix the rubber sleeve 3 to the air inlet 12. One drawback of this approach is that it requires the addition of a clamp 4, which increases both the number of components and the product cost. Secondly, since high-frequency welding of the cover 1 to the shell 2 and fixing the rubber sleeve 3 to the air inlet 12 using the clamp 4 are two different types of fixing methods, and it is impossible to fix the rubber sleeve 4 to the air inlet 12 using high-frequency welding, using two different processes for assembling the same component of a product will affect assembly efficiency and increase unnecessary equipment investment. This is because high-frequency welding and clamp 4 assembly each use different types of equipment; for example, the former uses a high-frequency welding robot, while the latter uses a clamp installation robot or manual assembly. Manual assembly wastes valuable labor resources, and the quality of assembly is also related to the assembler's sense of responsibility and mood. Utility Model Content

[0003] The objective of this invention is to provide an improved cover structure for a refrigeration compressor intake muffler that allows the fixing method of the rubber sleeve to the air inlet to be consistent with the fixing method of the cover to the shell, thereby eliminating the need for clamps, reducing the number of parts, lowering product costs, ensuring assembly quality, and improving assembly efficiency.

[0004] The present invention achieves its objective as follows: an improved cover structure for a refrigeration compressor intake muffler includes a cover that is fixed to the upper open portion of the housing during use. An air inlet extending from the left side of the cover and communicating with the cover cavity is present, and an air outlet extending upward from the top of the cover, also communicating with the cover cavity, is present. A rubber sleeve is fitted onto the air inlet at one end. The invention is characterized by a cover plastic sealing flange formed on the lower edge of the cover and around its perimeter on the outward-facing side. This cover plastic sealing flange engages with a housing plastic sealing flange formed on the outer side of the upper open portion of the housing and is sealed by a plastic sealing strip. A rubber sleeve plastic sealing ring is formed on the outer side corresponding to the end of the rubber sleeve facing the air inlet, fixing the end of the rubber sleeve facing the air inlet by the rubber sleeve plastic sealing ring, and the rubber sleeve plastic sealing ring is engaged with the plastic sealing strip.

[0005] In a specific embodiment of this utility model, the cross-sectional shape of the plastic seal strip is as follows: The shape of the character.

[0006] In another specific embodiment of this utility model, the housing is composed of symmetrical front and rear half-shells that are merged face to face.

[0007] In another specific embodiment of this utility model, the splicing part corresponding to the merging of the front and rear half shells is fixed by the plastic sealing strip of the front and rear half shells.

[0008] The technical solution provided by this utility model eliminates the need for clamps in existing technologies by fixing the rubber sleeve to the air inlet in the same way as fixing the cover to the shell. This not only reduces the number of parts and lowers product costs, but also ensures assembly quality and improves assembly efficiency. Attached Figure Description
