In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model discloses an air deodorizing and disinfecting device, including a device body 1, and the device body 1 is composed of an air intake part and a filter part detachably installed at the bottom of the air intake part, the air intake part is used to inhale air into the filter part, and discharge the filtered air from the output end of the air intake part, the filter part includes a lower shell 11 and a purification filter element 16 arranged in the lower shell 11, an outer filter screen 15 is arranged at the bottom of the air intake part, and the outer filter screen 15 is sleeved on the outside of the purification filter element 16 to isolate particulate impurities in the air.

[0024] In one embodiment, the device also includes a scraper frame 2, which has a ring-shaped shape and is arranged on the upper side of the inner wall of the lower shell 11. The scraper frame 2 is used to scrape off impurities on the outer filter 15 when it is limited and the outer filter 15 rises. An outer scraper ring 7 is arranged on the lower side of the outer wall of the outer filter 15. The outer scraper ring 7 is used to rise synchronously with the outer filter 15 when the outer filter 15 rises to scrape off impurities on the inner wall of the lower shell 11, and a locking device 3 is arranged on the inner wall of the lower shell 11. The locking device 3 cooperates with the scraper frame 2. The locking device 3 is used to limit the scraper frame 2, and the locking device 3 will release the limit on the scraper frame 2 when it contacts the outer scraper ring 7 when it rises. After the limit is released, the scraper frame 2 will move synchronously with the outer scraper ring 7.

[0025] In the specific implementation, when it is necessary to clean the outer filter 15, the staff moves the air intake part upward, and the outer filter 15 is simultaneously pulled out from the lower shell 11. At this time, the outer filter 15 will continue to contact with the scraper frame 2 when it rises, and the impurities on the outer filter 15 will be scraped off by the scraper frame 2, and the impurities will fall onto the outer scraper ring 7. At the same time, the outer filter 15 will drive the outer scraper ring 7 on its lower side to rise synchronously when it rises, and the outer scraper ring 7 will scrape off the impurities attached to the inner wall of the lower shell 11, and the impurities will also gather on the outer scraper ring 7. When the outer scraper ring 7 rises and contacts the locking device 3, the locking device 3 releases the limit on the scraper frame 2, so that the scraper frame 2 and the outer scraper ring 7 are both pulled out of the lower shell 11 along with the outer filter 15. At this time, the impurities are all on the outer scraper ring 7, which is very convenient to clean.

[0026] In one embodiment, the air intake portion includes an upper shell 12 detachably mounted on the top of the lower shell 11, fan blades 14 rotatably mounted in the upper shell 12, and a power device 13 mounted on the upper shell 12 and used to drive the fan blades 14 to rotate. The power device 13 is an electric motor device, and both the lower shell 11 and the upper shell 12 are provided with inlets and outlets for air to enter and exit.

[0027] With such a design, when the power device 13 is started, air will be sucked in from the inlet and outlet on the lower shell 11, and the air will pass through the outer filter 15 and the purification filter element 16, wherein the outer filter 15 is used to block impurities in the air, the impurities are blocked on the outer wall of the outer filter 15, and are cleaned according to the above-mentioned operation method, and the purification filter element 16 is used to deodorize and disinfect the air. The purification filter element 16 can be an adsorbent filter element, which is used to adsorb harmful gases, odors and volatile organic compounds in the air. The filter part also includes a sealing ring 18 installed on the upper shell 12 and a sealing seat 19 installed on the inner bottom wall of the lower shell 11, and the sealing ring 18 contacts the top of the purification filter element 16, and the bottom of the purification filter element 16 is inserted into the sealing seat 19, thereby preventing the treated air from contacting impurities.

[0028] A base 17 is installed at the bottom of the lower shell 11, and a universal wheel with a brake pad structure is movably installed at the bottom of the base 17. This design allows the device to be flexibly moved to a corresponding position, and the brake pad can be operated to lock the universal wheel when it is not moving.

[0029] In one embodiment, the outer filter 15 is detachably mounted on the bottom of the upper shell 12 , and the bottoms of the outer filter 15 and the purification filter element 16 are both provided with a sealing layer in contact with the sealing seat 19 , and the sealing layer may be an annular silicone ring.

[0030] With such a design, after the outer filter 15 is pulled out, it can be directly removed from the upper shell 12, and its installation method can be fixed by bolts, thereby further improving the flexibility of processing, and the setting of the sealing layer can make the outer filter 15 and the purification filter element 16 better sealed after contacting the sealing seat 19.

[0031] In one embodiment, an installation cavity is provided on the inner wall of the lower shell body 11, and the locking device 3 includes a spring 31 installed horizontally in the installation cavity, a locking block 32 installed on the spring 31, and a locking groove 33 provided in the locking block 32. A locking piece 4 that is snap-fitted into the locking groove 33 is installed at the bottom of the scraper frame 2. The locking groove 33 is wide at the bottom and narrow at the top. The shape of the locking piece 4 is consistent with the locking groove 33 and cooperates with each other. The locking groove 33 is open to one side at the center of the lower shell body 11. When the locking block 32 slides into the installation cavity, the locking piece 4 can slide out of the locking block 32 through the opening and separate from it. The locking block 32 is triangular in shape, and its upper and lower sides are inclined. The scraper frame 2 abuts against the locking block 32. The locking block 32 is used to release the limit on the locking piece 4 when the outer scraper ring 7 rises and pushes it into the installation cavity.

[0032] In a specific implementation, the locking block 32 is used to release the limiting state of the locking piece 4 when the outer scraper ring 7 rises and is pushed into the installation cavity. When in use, after the outer scraper ring 7 rises and contacts the locking block 32, the locking block 32 will be pushed laterally into the installation cavity. At this time, the locking piece 4 gradually disengages from the locking groove 33, thereby releasing the limiting state of the scraper frame 2.
