DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 12 As shown, the present invention provides an embodiment: a matrix muffler capable of increasing the airflow area, comprising a frame 1, wherein a filter assembly 2, a dust removal assembly 3, a drive assembly 4, a muffler assembly 5 and a guide assembly 6 are arranged inside the frame 1, the filter assembly 2 comprises a symmetrically arranged coarse filter 21 and a fine filter 22, the frame 1 is symmetrically slidably connected with a mounting seat 23, the coarse filter 21 and the fine filter 22 are both fixedly connected between the two mounting seats 23, the dust removal assembly 3 comprises a support seat 31 symmetrically fixedly connected to the outer wall of the frame 1, the frame 1 is fixedly connected with a guide sleeve 32, and a cleaning mechanism 33 is arranged between the two support seats 31; The cleaning mechanism 33 includes a cleaning block 331, and the number of the cleaning blocks 331 is set to four. The support seat 31 is slidably connected to a movable seat 333 and a slider 334. The movable seat 333 is evenly fixedly connected to a limiting rod 335 on one side close to the slider 334. The slider 334 is slidably connected to the outer side of the limiting rod 335. The movable seat 333 is symmetrically fixedly connected to a side away from the slider 334 with two groups of four fixed blocks 332. The cleaning blocks 331 are all fixedly connected to the fixed blocks 332. The driving assembly 4 includes a driving belt 44 that is drivingly connected to the support seat 31. The support seat 31 is evenly rotatably connected to the driving shaft 41. One end of the driving shaft 41 located in the driving belt 44 is fixedly connected to the driving wheel 45. A fixing rod 336 is fixedly connected inside the transmission belt 44, and the fixing rod 336 is rotatably connected to the slider 334; A fixing plate 24 is fixedly connected inside the frame 1 , and the mounting seat 23 is slidably connected between the fixing plate 24 and the frame 1 .

[0020] In practical application, the embodiment of the present invention is as follows: Figure 1 , Figure 3 and Figure 5 As shown, the airflow first enters the frame 1, and when passing through the filter assembly 2, the coarse filter 21 and the fine filter 22 perform preliminary filtering on large particles and some small particles in the airflow; like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 and Fig.10 As shown, the filtered large-area airflow is guided by the guide component 6, so that the airflow passes through the muffler body 53 accurately. In this process, the guide component 6 cooperates with the driving component 4 to realize the driving of the driving shaft 41 in the driving component 4. The rotating driving shaft 41 drives the transmission belt 44 to rotate inside the support seat 31 through the driving wheel 45. The rotating transmission belt 44 drives the slider 334 through the fixed rod 336, so that the slider 334 slides on the outside of multiple limit rods 335 and drives the cleaning mechanism 33 to move up and down synchronously. The movement of the cleaning mechanism 33 can drive the cleaning block 331 to move through the fixed block 332 to realize the cleaning of the surface of the coarse filter 21 and the fine filter 22, so as to avoid impurities clogging and affecting the filtering effect, further reduce the probability of impurities entering the muffler component 5, improve the protection of the components inside the muffler component 5, and further improve the muffler effect and environmental protection.

[0021] like Figure 6 As shown, the silencer assembly 5 includes a mounting sleeve 51 fixedly connected to the frame 1, a connecting seat 52 is evenly fixedly connected inside the mounting sleeve 51, a silencer body 53 is fixedly and slidably connected inside the connecting seat 52, a support frame 54 is fixedly connected inside the mounting sleeve 51, a fixing seat 55 is fixedly connected to the side of the silencer body 53 close to the support frame 54, and the fixing seat 55 is slidably connected to the inner side of the support frame 54.

[0022] When the embodiment of the present invention is actually used, the airflow after filtering and preliminary cleaning enters the silencer assembly 5. The mounting sleeve 51 carries the silencer body 53, and the connecting seat 52 inside it provides a stable mounting position for the silencer body 53. The fixed sliding connection of the silencer body 53 in the connecting seat 52 ensures working stability and buffers external forces. The fixed seat 55 of the silencer body 53 is slidably connected to the support frame 54 to enhance its stability in the mounting sleeve 51. When the airflow passes through, the muffler body 53 arranged in a matrix uses its own structure and acoustic materials to reduce noise, increase the contact area and time between the airflow and the silencer structure, improve the silencer effect, and reduce the silencer resistance, so that the silencer assembly 5 can work stably and efficiently in a complex airflow environment and meet the noise control requirements.

[0023] like Figure 7 and Figure 8 As shown, the guide assembly 6 includes a mounting frame 61 fixedly connected to the frame 1 , a guide seat 62 is evenly fixedly connected inside the mounting frame 61 , and a fixing sleeve 63 is fixedly connected inside the guide seat 62 .

[0024] When the embodiment of the present invention is actually used, after the airflow enters the guide assembly 6, the installation frame 61 provides a stable installation base for the guide seat 62, and the guide seat 62 evenly distributed in the installation frame 61 guides the airflow, so that the airflow flows in the designed direction. The fixed sleeve 63 is fixed inside the guide seat 62, which can further optimize the flow state of the airflow, reduce the turbulence of the airflow during the guiding process, ensure that the airflow can flow to the silencer assembly 5 accurately and smoothly, and ensure that the silencer process is carried out smoothly and efficiently.

[0025] like Figure 4 , Figure 7 and Figure 8 As shown, the driving assembly 4 also includes a mounting shaft 46 rotatably connected to the frame 1 and the inside of the fixed sleeve 63, one end of the mounting shaft 46 located in the fixed sleeve 63 is fixedly connected to the impeller 47, both ends of the mounting shaft 46 are fixedly connected to the end toothed disc 42, the outer side of the driving shaft 41 is fixedly connected to the spur gear 43, and the end toothed disc 42 and the spur gear 43 are meshed with each other.

[0026] In actual application of the embodiment of the present invention, when air flows through, the air flows on the impeller 47 to rotate the mounting shaft 46. The end toothed discs 42 at both ends of the mounting shaft 46 rotate, and since the end toothed discs 42 mesh with the spur gears 43 on the drive shaft 41, the drive shaft 41 is driven to rotate, and the rotation of the drive shaft 41 further drives the transmission belt 44 to move. The transmission belt 44 drives the cleaning block 331 to clean the filter screen through the connection relationship with the slider 334, realizing the function of using the energy of the air flow itself to drive the cleaning mechanism 33, ensuring the continuous and effective operation of the filter assembly 2, and maintaining the good operating state of the entire muffler body 53.

[0027] like Figure 8 As shown, a sealing seat 64 is fixedly connected to the top of the fixing sleeve 63 , and a sealing cavity adapted to the impeller 47 is formed at the bottom of the sealing seat 64 .

[0028] When the embodiment of the present invention is actually used, the sealing cavity adapted to the impeller 47 opened at the bottom of the sealing seat 64 can effectively reduce the leakage of the airflow when passing through the impeller 47, ensuring that the airflow energy is used as much as possible to drive the impeller 47 to rotate. At the same time, the adaptive design of the sealing cavity and the impeller 47 can make the airflow environment around the impeller 47 more stable, reduce the influence of airflow leakage or turbulence on the rotation efficiency of the impeller 47, and thus ensure the stable operation of the drive assembly 4, and provide reliable power for the normal operation of related components such as the cleaning mechanism 33.

[0029] like Fig.11 and Fig.12 As shown, a vibration mechanism 34 is arranged inside the movable seat 333, and the vibration mechanism 34 includes a rack 341 symmetrically fixedly connected to the fixed plate 24, and a connecting block 342 is symmetrically fixedly connected to one side of the mounting seat 23 close to the movable seat 333, and a cylindrical gear 343 and a cam 344 are rotatably connected inside the cleaning mechanism 33, and the cylindrical gear 343 and the rack 341 are meshed with each other, and the cylindrical gear 343 and the cam 344 are fixedly connected.

[0030] In actual application of the embodiment of the present invention, when the cleaning mechanism 33 cleans the coarse filter 21 and the fine filter 22, the cylindrical gear 343 meshes with the rack 341. As the movable seat 333 moves, the cylindrical gear 343 rolls on the rack 341, thereby driving the cam 344 fixedly connected thereto to rotate. The connecting block 342 on one side of the mounting seat 23 cooperates with the cam 344. The rotation of the cam 344 repeatedly strikes the connecting block 342, causing the connecting block 342 to vibrate. The vibration is transmitted to the coarse filter 21 and the fine filter 22 through the mounting seat 23, causing the filter to vibrate additionally, further enhancing the cleaning effect of impurities on the filter, and preventing impurities from firmly adhering to the filter surface and affecting the filtering efficiency.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
