[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a double-inlet fresh air purifier, including a housing 1, the right end side wall of the housing 1 is fixedly connected with an air outlet pipe 3 through a telescopic hose 2, one end of the telescopic hose 2 is connected to the purification device inside the housing 1, the other end of the telescopic hose 2 is fixedly connected with the air outlet pipe 3, the air is transmitted from the telescopic hose 2 to the air outlet pipe 3 through the purification device, the top end of the air outlet pipe 3 is fixedly connected with a fixed rod 4, the outer wall of the fixed rod 4 is fixedly connected with a gear 5, the outer wall of the gear 5 is engaged with a rack 6, when the rack 6 moves left and right, it will cause the gear 5 to rotate forward and backward, the top end of the rack 6 is fixedly connected with a connecting plate 7, the bottom end of the connecting plate 7 is fixedly connected with a sleeve 8, refer to Figure 4 , a positioning mechanism is provided on the inner wall of the sleeve 8, the right end side wall of the housing 1 is fixedly connected with a mounting plate 16, the mounting plate 16 mainly plays a role in supporting and connecting the entire gear 5, rack 6 and connecting plate 7, and the left end side wall of the housing 1 is fixedly connected with an air inlet pipe 11.

[0033] Refer to Figure 1 , Figure 5 And Figure 6, the inner wall of the bottom end of the air inlet pipe 11 is elastically connected with a limiting block 13 through a positioning spring 12. A guide pipe 14 is fixedly connected to the inner wall of the air inlet pipe 11. The guide pipe 14 allows the limiting block 13 to slide along the inner wall of the air inlet pipe 11 without deviation of the movement track. A dust-proof frame 15 is inserted into the left end of the air inlet pipe 11. A filter screen is arranged on the dust-proof frame 15, which can block pollutants such as particulate matter, dust, and pollen that may be contained in the external air by using the filter screen. The inner wall of the bottom end of the air inlet pipe 11 is fixedly connected to one end of the positioning spring 12. When the limiting block 13 moves downward, it will compress the positioning spring 12. When resetting, the elastic force of the positioning spring 12 is used to drive the limiting block 13 to reset. The other end of the positioning spring 12 is fixedly connected to the bottom end of the limiting block 13. The limiting block 13 is slidably connected to the inner wall of the air inlet pipe 11. The limiting block 13 is clamped with the inner side wall of the dust-proof frame 15. An L-shaped groove is formed on the dust-proof frame 15, which can allow the limiting block 13 to be clamped with its inner wall to limit the entire dust-proof frame 15. And there is an opening on the inner side wall of the dust-proof frame 15, which can be inserted into the protruding part of the air inlet pipe 11 to initially position and install the dust-proof frame 15. The limiting block 13 is slidably connected to the outer wall of the guide pipe 14.

[0034] Refer to Figure 4 , the positioning mechanism includes a clamping plate 10. One end of a reset spring 9 is fixedly connected to the top end of the clamping plate 10. When the clamping plate 10 moves downward, it will stretch the reset spring 9. When resetting, the elastic force of the reset spring 9 is used to drive the clamping plate 10 to reset. The other end of the reset spring 9 is fixedly connected to the bottom end of the connecting plate 7. The clamping plate 10 is clamped with the bottom end of the mounting plate 16. A plurality of notches corresponding to the clamping plate 10 are formed at the bottom end of the mounting plate 16, which can allow the clamping plate 10 to be clamped with the notches at its bottom end to limit the position of the connecting plate 7. The clamping plate 10 is slidably connected to the inner wall of the sleeve 8.

[0035] Refer to Figures 1 - 3 , the sleeve 8 penetrates and is slidably connected to the inner wall of the mounting plate 16. A notch is formed on the mounting plate 16, which can allow the sleeve 8 to slide along its inner wall. The fixing rod 4 penetrates and rotates in the inner wall of the mounting plate 16. The rack 6 contacts the top end of the mounting plate 16.

[0036] Working principle: When it is necessary to send the processed air to two different areas respectively, only need to pull down the clamping plate 10 and stretch the return spring 9, so that the clamping plate 10 is separated from the bottom slot of the mounting plate 16, and the clamping pipe 10 can drive the sleeve 8, the connecting plate 7 and the rack 6 to move left and right, so that the rack 6 drives the gear 5, the fixed rod 4 and the air outlet pipe 3 to rotate with the telescopic hose 2. Since the length of the telescopic hose 2 is fixed, when rotating, the telescopic hose 2 will extend out of the housing 1, and according to the actual situation, the outlets of the air outlet pipe 3 can be rotated to approach or separate from each other, so that the outlets of the air outlet pipe 3 can distribute the air to different areas, or the air in the air outlet pipe 3 can be concentrated in one area. When limiting is needed, just release the clamping plate 10 and use the reverse elastic force of the return spring 9 to drive the clamping plate 10 to reset, so that the clamping plate 10 is clamped with the bottom end of the mounting plate 16, and the position of the entire connecting plate 7 is limited so that the position of the air outlet pipe 3 will not change. When adjusting again, just operate according to the above steps.

[0037] When it is necessary to maintain and clean the filter screen of the air inlet pipe 11, only need to move the limit block 13 downward so that the limit block 13 coincides with the opening of the L-shaped groove of the dust-proof frame 15. At this time, the positioning spring 12 is in a compressed state, and the L-shaped groove of the dust-proof frame 15 can be separated from the limit block 13. After cleaning, the dust-proof frame 15 can be inserted into the air inlet pipe 11 first, so that the limit block 13 coincides with the opening of the L-shaped groove, and finally release the limit block 13 and use the reverse elastic force of the positioning spring 12 to drive the limit block 13 to reset, so that the limit block 13 is clamped with the inner wall of the L-shaped groove of the dust-proof frame 15.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
