[0028] Example 1:
[0029] See also Figure 1-5 , an air intake mechanism for an air compressor, comprising a filter bin 1 and connecting pipes 2 located at the front and rear ends of the filter bin 1, a pair of connecting pipes 2 are connected to the air intake pipe and the air compressor pipe at one end away from the filter bin 1, the inner end of the filter bin 1 is provided with a storage groove 101, a positioning plug-in plate 3 is inserted into the storage groove 101, the positioning plug-in plate 3 is made of lightweight material, a horizontal slide groove 301 is provided at the lower end of the positioning plug-in plate 3, a filter screen plate 4 is slidably connected in the horizontal slide groove 301, the filter screen plate 4 is also slidably connected to the storage groove 101, and the filter screen plate 4 The outer end is fixedly connected with a sealing layer, which effectively improves the sealing performance of the filter screen plate 4 after being installed in the filter bin 1 through the sealing layer, so as to prevent air leakage during the air intake process of the air compressor. The horizontal slide groove 301 is a trapezoidal groove, and the shape of one end of the filter screen plate 4 located in the horizontal slide groove 301 matches it. A micro-magnetic plate 304 is embedded in the inner bottom end of the horizontal slide groove 301. The filter screen plate 4 is located in one end of the horizontal slide groove 301 and the position corresponding to the micro-magnetic plate 304 is made of ferromagnetic material, and the remaining positions are made of lightweight materials. After being assembled into the transverse chute 301, the filter screen plate 4 is slid to the inner bottom end of the transverse chute 301 by the magnetic attraction, so that when the filter screen 5 needs to be maintained or replaced after a long period of use, the positioning plug-in plate 3 and the filter screen plate 4 are taken out from the storage slot 101. Due to the influence of the shapes of the two and the magnetic attraction, the filter screen plate 4 and the positioning plug-in plate 3 will be taken out together, and the two will not be separated. In addition, the magnetic attraction provided by the micro-magnetic plate 304 is limited, and it will not affect the difficulty of separating the filter screen plate 4 from the positioning plug-in plate 3. A filter screen 5 is provided on the filter chamber 1. The connecting pipe 2 and the filter screen 5 are coaxially arranged, and the diameter of the filter screen 5 is larger than the diameter of the connecting pipe 2, so as to ensure that floating objects in the air entering the air intake pipe end are effectively filtered and intercepted. It is worth noting that the user can set multiple positioning plug-ins 3, filter screen plates 4 and filter screens 5 of different specifications on the filter chamber 1 according to usage requirements, so as to improve the filtering and interception effect, thereby maximally preventing the influence of impurities in the air on the air compressor. A quick-install component is also provided between the filter chamber 1 and the positioning plug-in plate 3;
[0030] The quick-install component includes a pair of assembly slots 302 and longitudinal adjustment slots 303 provided at the left and right ends of the positioning plugboard 3, and the assembly slots 302 and the longitudinal adjustment slots 303 are connected. A pair of positioning slots 102 arranged parallel to the assembly slots 302 are provided in the filter chamber 1, and a positioning block 6 is slidably connected in the assembly slot 302. A micro spring 7 is fixedly connected between the positioning block 6 and the inner bottom end of the assembly slot 302. The end of the positioning block 6 away from the micro spring 7 is movably abutted against the positioning slot 102. The positioning slot 102 is a concave hemispherical slot body, and the shape of the end of the positioning block 6 close to the positioning slot 102 matches it. When the end of the positioning block 6 away from the micro spring 7 abuts against the positioning slot 102, it means that the positioning plugboard 3 and the filter screen plate 4 are installed in place. At this time, the filter screen 5 is coaxial with the connecting pipe 2. The upper end of the positioning block 6 is fixedly connected to a connecting rod 8, which is arranged in the longitudinal adjustment groove 303 and slidably connected thereto. The upper end of the connecting rod 8 is fixedly connected to an adjusting block 9, which is located at the outer end of the longitudinal adjustment groove 303, and the adjusting block 9 is slidably connected to the upper surface of the positioning plugboard 3. The lower end of the adjusting block 9 is coated with a smooth coating. Since the elastic potential energy of the micro-spring 7 is small, the pair of adjusting blocks 9 are moved toward one end close to each other, which can easily drive the connecting rod 8 and the positioning block 6 below to move synchronously. The end of the adjusting block 9 away from the connecting rod 8 is fixedly connected to a hook ring 10, and the outer end of the hook ring 10 is provided with a rubber layer, the shape of the rubber layer matches it, and when the positioning block 6 is fully moved into the assembly groove 302, the positioning plugboard 3 and the filter screen plate 4 can be taken out through the hook ring 10.
[0031] When using the air intake mechanism of the air compressor, when installing a new filter 5, first, install the filter plate 4 into the horizontal slide groove 301 and install it in place through the magnetic attraction. Then put the spliced positioning plug plate 3 and the filter plate 4 into the storage groove 101 until the positioning block 6 abuts against the positioning groove 102. At this time, the filter 5 is coaxial with the connecting pipe 2. The filter 5 can filter the floating objects and impurities in the cavity from the intake pipe end. When the filter 5 needs maintenance or replacement after being used for a period of time, hook the hook ring 10 and squeeze the pair of adjustment blocks 9 toward the end where the two are close to each other. The filter screen 5 can be cleaned and maintained by the user through the use of the hook ring 10, or the filter screen 5 can be completely replaced by the user through the hook ring 10. Compared with the prior art, the utility model can ensure that the filter screen 4 is firmly connected to the positioning plug plate 3 during installation and use, and can greatly simplify the installation and removal process of the filter screen 5, so that the user can complete the operation easily and quickly when maintaining or replacing the filter screen 5, thereby greatly improving work efficiency and user experience.
[0032] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
