[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9 As shown, a ventilator according to one embodiment of the present invention includes a ventilator housing 1 having a support 11 formed thereon, with a compressed air port (not shown) formed thereon. A cover 4 is placed over the support 11, with mesh holes 41 formed thereon, and a first filter 52 is mounted within the cover 4. When the ventilator is in operation, air is filtered through the first filter 52 and then drawn into the ventilator housing 1.

[0033] After long-term use, in addition to the need to replace the first filter 52, dust will also accumulate on the inner wall of the cover 4 and the placement table 11. Although the first filter 52 can be replaced, the dust accumulated on the inner wall of the cover 4 and the placement table 11 is not easy to clean, and requires professional personnel to disassemble the machine, and the cleaning work is more troublesome.

[0034] In order to facilitate the cleaning of dust, Figures 2 to 9 As shown, a filter box 2 is detachably mounted on the placement table 11. The filter box 2 covers the placement table 11, so that dust originally falling on the placement table 11 falls on the filter box 2. The filter box 2 includes a first box wall 21, a second box wall 22, and a third box wall 23. The third box wall 23 is a pair. The opposing panels of the pair of third box walls 23 are provided with a second slide groove 231. A second slider 43 is welded to the opposite side wall of the cover body 4. The second slider 43 matches the second slide groove 231. The cover body 4 is slidably connected to the filter box 2 via the second slider 43.

[0035] Specifically, the width of the second slider 43 gradually increases from one end to the other end. When plugging in, the relatively narrow end of the second slider 43 is first inserted into the second slide groove 231. When the wider end of the second slider 43 is inserted into the second slide groove 231, it has an interference fit with the second slide groove 231, so that the cover body 4 can be firmly installed on the filter box 2.

[0036] Furthermore, a protrusion 42 is integrally formed on the outer wall of the cover 4. When installing or removing the cover 4, the protrusion 42 is pressed and then pushed. The protrusion 42 increases the friction between the hand and the side wall of the cover 4 to prevent slipping. At the same time, the protrusion 42 also strengthens the side wall of the cover 4 to prevent the side wall of the cover 4 from being dented or damaged due to force.

[0037] Furthermore, the side wall of the cover body 4 has an arc-shaped section, and the grid holes 41 are opened on the arc-shaped section of the cover body 4, which can increase the air intake volume and improve the inhalation efficiency of the ventilator.

[0038] When cleaning dust, press the protrusion 42 and push the cover 4 toward the side of the respirator housing 1 to make the cover 4 slide out of the filter box 2, and then take the filter box 2 out of the placement table 11. You can clean the dust on the cover 4 and the filter box 2, and it is also convenient to replace the first filter 52.

[0039] In order to make the filter box 2 fixed on the placement table 11, as shown in FIG. Figures 2 to 7 As shown, a first slide groove 12 is provided on the placement table 11, and the first slide groove 12 is rectangular. A positioning groove 13 is provided on the ventilator housing 1, and the positioning groove 13 is connected to the first slide groove 12 and is vertically downward relative to the first slide groove 12. A locking assembly is fixedly connected to one side wall of the second box wall 22. The locking assembly includes a first slider 221 and a rotating shaft 3. The first slider 221 is welded to one side wall of the second box wall 22. A rotating hole is provided on the first slider 221. The rotating shaft 3 passes through the rotating hole on the first slider 221 and is rotatably connected to the rotating hole on the first slider 221. A baffle 31 is welded on one end face of the rotating shaft 3. The length of the baffle 31 matches the long side size of the first slider 221. An indicator mark is provided on the end face of the rotating shaft 3 away from the welding baffle 31.

[0040] Specifically, the first slider 221 is a rectangle that matches the first slide groove 12. Insert the first slider 221 into the first slide groove 12. When the tail of the rotating shaft 3 is against the groove wall of the first slide groove 12, rotate the rotating shaft 3 counterclockwise. When the indicator mark on the rotating shaft 3 is vertical, the baffle 31 is clamped in the positioning groove 13, and the filter box 2 can be fixed on the placement table 11.

[0041] When it is necessary to clean the accumulated dust on the filter box 2, the rotating shaft 3 is rotated. When the indicator mark on the rotating shaft 3 is horizontal, the blocking piece 31 is separated from the range of the positioning groove 13. The rotating shaft 3 is pulled outward, and the blocking piece 31 abuts against the end surface of the first slider 221, thereby driving the filter box 2. The filter box 2 can be removed from the placement table 11, making it easier to clean the filter box 2.

[0042] Furthermore, an air inlet 211 matching the compressor fan port is opened on the first box wall 21. When the filter box 2 is fixed on the placement table 11, there is a certain distance between the first box wall 21 and the side wall of the placement table 11, and a second filter 51 is installed between the first box wall 21 and the side wall of the placement table 11.

[0043] Preferably, the second filter 51 is an activated carbon filter, which can absorb moisture, formaldehyde, benzene and other substances in the air, making the air entering the respirator housing 1 cleaner.

[0044] Specifically, when the ventilator is operating, air enters through the mesh holes 41 on the cover 4, passes through the first filter 52 to filter dust, and then passes through the second filter 51. When the filter box 2 is removed for cleaning, the first filter 52 and the second filter 51 are replaced simultaneously. After replacement, the filter box 2 is installed, and the first box wall 21 and the side wall of the placement table 11 can clamp the first filter 52, so that the first filter 52 is fixed in the filter box 2.

[0045] During use, first press the protrusion 42 on the cover 4 and push the cover 4 toward the outside of the ventilator housing 1, so that the cover 4 slides out of the filter box 2. Then, rotate the shaft 3. When the indicator mark on the shaft 3 is horizontal, pull the shaft 3 outward, and the shaft 3 will drive the filter box 2 to be removed from the placement table 11. Then, the filter box 2 and the cover 4 can be cleaned, and the second filter 51 and the first filter 52 can be replaced.

[0046] After cleaning, insert the first slider 221 on the filter box 2 into the first slide groove 12, rotate the rotating shaft 3, and when the indicator mark on the rotating shaft 3 is vertical, the baffle 31 will be clamped in the positioning groove 13, and the first slide groove 12 will be fixed on the placement table 11, and then the cover body 4 can be inserted into the filter box 2.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
