Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a dustproof and noise-reducing air compressor. Background Technology

[0002] In air compressors, the air intake source of the blower and motor fan is usually an important air circulation channel to ensure the normal operation of the equipment and prevent overheating.

[0003] To prevent large foreign objects from entering the equipment and damaging the fan, traditional designs typically incorporate filter sponges within a perforated mesh layer on the inside of the housing. However, in current designs, the filter sponge is located inside the housing, requiring the system to be shut down and the inlet door removed before it can be retrieved and cleaned. This maintenance method not only increases equipment downtime but also reduces maintenance efficiency and impacts the timeliness of maintenance. Furthermore, operating noise from the main unit and other components inside the housing can be directly transmitted through this door. Utility Model Content

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In addition, to clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The top, bottom, front, back, left, and right sides are shown.

[0020] like Figures 1 to 3 The present application provides a dustproof and noise-reducing air compressor, which includes: a housing 11, an air compressor assembly 12, and a filter assembly 13.

[0021] Specifically, an air inlet 111 is provided on the right side wall of the housing 11. An air compressor assembly 12 is disposed inside the housing 11 for compressing air. A filter assembly 13 is disposed on the air inlet 111 for filtering foreign objects in the air.

[0022] More specifically, the filter assembly 13, from the outside of the housing 11 inwards, includes an inner door 131, a filter cloth, and a shielding member 132. The shielding member 132 is fixedly connected to or integrally formed with the air inlet door 111. The bottom of the inner door 131 has several snap-fit ​​pieces 1311, which snap onto the air inlet door 111. The top of the inner door 131 has several magnetic pieces 1312, which magnetically attract the shielding member 132. The filter cloth is disposed between the inner door 131 and the shielding member 132, and is detachably mounted on the inner door 131.

[0023] The aforementioned air compressor, by installing a filter assembly 13 on the air inlet door 111, can effectively reduce the amount of dust entering the housing 11, improve air quality, and extend the service life of the air compressor. The design of using snap-fit ​​parts 1311 and magnetic attachments 1312 to fix the inner door 131 makes filter cloth replacement more convenient. The inner door 131 can be quickly removed and the filter cloth pulled out without stopping the air compressor, and then reinstalled, ensuring normal machine operation. After the filter cloth is cleaned, it can be reinstalled on the inner door 131, reducing maintenance costs and improving production efficiency.

[0024] like Figure 2 As shown, the shielding component 132 includes several wind deflectors 1321 and micro-perforated mesh plates 1322 arranged in a vertical direction. The micro-perforated mesh plates 1322 are located to the left of the wind deflectors 1321 and are used to absorb the noise generated during the operation of the air compressor assembly 12, reducing noise pollution. Each wind deflector 1321 is connected to a corresponding micro-perforated mesh plate 1322, forming a herringbone structure. This herringbone structure can effectively optimize the airflow direction, reduce wind resistance, ensure air intake, and further improve the noise reduction effect of the shielding component 132.

[0025] like Figure 4 As shown, the air inlet 111 has support plates 1111 on the upper, lower, front, and rear sides of the baffle 132. The front and rear sides of the baffle plate 1321 each have first connecting portions 1321a, which are fixedly connected to the support plates 1111. The front and rear sides of the microporous mesh plate 1322 each have second connecting portions 1322a, which are fixedly connected to the support plates 1111. Through these arrangements, the baffle 132 is more securely fixed, improving the overall stability of the air compressor.

[0026] like Figure 3As shown, magnetic components 1312 are respectively provided on the front and rear edges of the top of the recessed door 131. The magnetic components 1312 are attracted to the first connecting part 1321a at the top. While ensuring the structural stability of the recessed door 131, the fixing structure is simplified, disassembly and installation are convenient, and maintenance efficiency is improved.

[0027] The bottom of the recessed door 131 is provided with snap-fit ​​parts 1311 at both the front and rear ends. The support plate 1111 located below the shield 132 is provided with a corresponding snap-fit ​​interface 1111a. By engaging the snap-fit ​​parts 1311 and the snap-fit ​​interface 1111a, the recessed door 131 is snapped into place with the air inlet door 111, making the recessed door 131 less prone to loosening in the working state and ensuring the stability of the recessed door 131 structure.

[0028] like Figure 1 As shown, the recessed door 131 has mesh holes 1313 to ensure air intake and protect the filter cloth and shield 132.

[0029] Furthermore, the filter cloth is specified as 3000 mesh / m² to provide high filtration accuracy, effectively remove fine particles from the air, improve the working efficiency of the air compressor, and reduce equipment wear caused by dust. Understandably, depending on actual needs, the filter cloth specification can be adjusted to 2000 mesh / m², 4000 mesh / m², or other models to improve applicability.

[0030] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
