Micro-miniature air compressor lifting handle integrated with air filtering and air intake silencing functions

Abstract

The invention belongs to the technical field of compressors and relates to a micro-miniature air compressor lifting handle. The lifting handle is integrated with air filtering and air intake silencing functions and is even provided with a starting capacitor for a compressor. Due to the adoption of the measures, parts and the volume of the compressor can be reduced, so that the manufacturing and assembling costs of the compressor can be reduced, and the packaging and transporting costs of the compressor can be reduced; in addition, the exposed-type assembled air filter and starting capacitor adopted in the past are improved to be of a storage-type installation way, so that not only is the risk that the parts are loosened reduced, but also the condition is created for improving the whole appearance modeling and layout of the compressor; and particularly, the volume of an air intake silencing cavity is greatly increased, so that the noise of the compressor can be greatly reduced, and furthermore the amenity is improved. Through function integration, the production cost of the compressor is reduced, and the working reliability and service amenity of the compressor are improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a handle of a compressor, in particular to a handle of a miniature air compressor, and more specifically to a miniature air compressor integrated with functions of air filtering and intake noise elimination. Handle for small air compressors. Background technique [0002] Micro-small air compressors usually refer to air compressors with an input power of less than 2 horsepower and an output displacement of less than 0.3 cubic meters per minute. It is characterized by small size, light weight, and convenient use and maintenance. , electronic packaging and food packaging industries have a very wide range of applications. As we all know, micro air compressors are mostly mobile devices that rely on manpower to carry, especially those micro air compressors with an input power below 1 horsepower. Air compressors are generally equipped with a hand-held handle or a hand-held handle. ...

AI Technical Summary

Problems solved by technology

However, due to the fixed thinking and design inertia, the current micro air compressor still adopts the traditional simple external assembly for these devices and accessories, that is, the above components are all exposed and explicit assembly.

[0003] Obviously, there are many deficiencies in the above-mentioned design scheme of the traditional miniature air compressor, which are mainly manifested in: 1) the single-function handle and the external air filter, the intake muffler and the starting capacitor need to be independently configured and tightened. The fastening device is connected to the body of the compressor or to the motor of the compressor or to the gas storage tank of the compressor. Obviously, these fastening connections cannot achieve resource sharing, so it is inevitable to increase the number of parts of the device, and thus increase the manufacturing and assembly. Therefore, it is very unfavorable to reduce the production cost of the compressor; 2) the single-function handle and the external air filter, intake muffler and starting capacitor are all exposed components Devices, as we all know, the working environment of micro air compressors is very complicated, with a lot of moving and handling, no fixed devices, large operating vibration, intersection of people and logistics, etc., so the above-mentioned external parts are loose and damaged during use. Probabilistic events, that is, the working reliability of the compressor is not high; 3) The single-function handle and external air filter, intake muffler and starting capacitor will undoubtedly cause the overall layout of the compressor to be relatively loose, The relatively large size and difficult handling of its appearance, on the one hand, increase the secondary cost of shipping and packaging, and on the other hand, cause the drawbacks of the overall appearance of the compressor to be sluggish and unfriendly; 4) The single-function handle and carrying Gas muffler, because its intake muffler can only rely on the intake muffler chamber set on the cylinder head of the compressor, as we all know, among the various noise components emitted by the compressor, the contribution value of the intake noise is the largest, while the contribution to the intake noise The main method of reduction is to use the sufficient volume of the intake chamber. Obviously, the larger the volume of the intake chamber, the greater the attenuation of the intake noise. There is no doubt that only the intake muffler chamber on the compressor is used to reduce noise. The effect of noise must be unsatisfactory, or not friendly enough in terms of agreeableness

To sum up, the design scheme of single-function handle and external air filter, intake muffler and starting capacitor in the traditional miniature air compressor inevitably has problems such as high production cost, poor working reliability and poor amenity
