[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: an air outlet type exhaust high-efficiency filtering device, including an exhaust box body 1, the exhaust box body 1 includes a mounting box 2, one side of the mounting box 2 is fixedly connected to an air inlet pipe 3, and both ends of the other side of the mounting box 2 are provided with limit rods 21, and the two limit rods 21 are slidably connected to a mounting frame 4, and a fixing frame 22 is provided on the mounting box 2 on one side of the limit rod 21, and a guide fan blade 23 is rotatably connected to the fixing frame 22; an air guide component 6 and a filter plate 5 are slidably connected between the two mounting frames 4, and a filter element 51 is provided on the filter plate 5, and the side wall of the filter plate 5 is provided with a filter element 51. There is a strip limit groove 52, and the air guide component 6 includes an air guide grille 61. Both sides of the air guide grille 61 are provided with a clamping block 62. Through the design of the air inlet pipe 3, the air enters the installation box 2 under the action of the compression groove 31, and the compressed air drives the fan blades 23 to rotate. At this time, the air is diffused to the surroundings under the action of the fan blades 23 to avoid air concentration. Further, under the action of the air guide component 6, the air is diverted into several areas, so that the filter element 51 is in contact with the air more evenly when filtering the air, which solves the technical problem of avoiding blockage of a certain part of the filter element 51 after being in contact with the air for a long time.

[0031] Furthermore, Figure 4 - Figure 5As shown: a compression groove 31 is provided on the air inlet pipe 3, and the angle of the compression groove 31 decreases from left to right. The side of the air guide grille 61 close to the air inlet pipe 3 is an inclined structure, and the angle of the air guide grille 61 increases from left to right. By increasing the area of ​​the compression groove 31 and reducing the area of ​​the compression groove 31, the device compresses the air under the action of the compression groove 31 when the air passes through. Further, under the design of the inclined structure of the air guide grille 61, the air guide grille 61 guides the air after contacting the air, so that the air contacts the filter element 51 after dispersion. Under the action of the compression groove 31, the air is compressed, so that the flow rate of the air is increased, thereby driving the fan blades 23 to rotate and diffusing the wind to the surroundings. Further, under the action of the air guide grille 61, the air is guided into several areas, so that the filter element 51 contacts the air more evenly when filtering the air, avoiding clogging of a certain part of the filter element 51 after contacting the air for a long time, thereby increasing the service life of the filter element 51.

[0032] When the mounting frame 4 is pulled out by the handle 41, the filter plate 5 and the air guide assembly 6 may fall directly from the bottom of the mounting frame 4. Figure 2 and Figure 5 As shown: the mounting frame 4 is provided with a first clamping groove 42, the air guide component 6 is slidably connected in the first clamping groove 42 through the clamping block 62, the mounting frame 4 is provided with a second clamping groove 43 on one side of the first clamping groove 42, and a strip-shaped limiting block 44 is provided at the bottom of the second clamping groove 43, the mounting frame 4 is provided with a first clamping groove 42, the air guide component 6 is slidably connected in the first clamping groove 42 through the clamping block 62, the mounting frame 4 is provided with a second clamping groove 43 on one side of the first clamping groove 42, and a strip-shaped limiting block 44 is provided at the bottom of the second clamping groove 43, and the strip-shaped limiting block 44 is correspondingly clamped with the strip-shaped limiting groove 52, and the two mounting frames 4 are away from the limiting grooves. A handle 41 is provided on one side of the rod 21, and the air guide assembly 6 is limited by the first clamping groove 42 to prevent the air guide assembly 6 from being displaced left and right between the mounting brackets 4 during use. The filter plate 5 is limited by the first clamping groove 42 to prevent the filter plate 5 from being displaced left and right between the mounting brackets 4 during use. Further, the strip limiting block 44 and the strip limiting groove 52 are mutually clamped to prevent the filter plate 5 from being displaced downward when the mounting bracket 4 is pulled out. The first clamping groove 42 and the clamping block 62 are mutually clamped to limit the air guide assembly 6 and the mounting bracket 4 to prevent the air guide assembly 6 from being displaced downward when the mounting bracket 4 is pulled out.

[0033] Working principle:

[0034] like Figure 1-5 As shown:

[0035] When in use: first, the exhaust box body 1 is embedded and installed in the designated position, and the air inlet pipe 3 is fixedly connected with the connecting pipe. When the air enters the air inlet pipe 3, the air is compressed under the action of the compression groove 31, so that the air flow rate is faster. When the compressed air contacts the fan guide blades 23, the thrust of the fan guide blades 23 drives the fan guide blades 23 to rotate, so that the fan guide blades 23 diffuse the air to the surroundings, and further under the action of the air guide assembly 6, the air is guided into several areas. At this time, the dispersed air is filtered by the filter element 51. During maintenance, the mounting frame 4 is pulled out by the handle 41 to replace the clogged filter element 51. Furthermore, the filter plate 5 and the air guide assembly 6 are slidably connected to the two mounting frames 4. When installing the filter plate 5 or the air guide assembly 6, just insert it into the corresponding slot. After the filter plate 5 and the air guide assembly 6 are installed, push the mounting frame 4 back into the mounting box 2.
