Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to a two-way air adjustment structure of an air outlet of an air purifier. Background Art

[0002] An air purifier, also known as an air cleaner, air freshener, or air purifier, is a product that can absorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), effectively improving air cleanliness. It is widely used in homes, buildings, factories, and other scenarios. An air purifier is equipped with a fan, and a duct component is usually used to guide the air discharged from the fan to circulate to the air outlet of the air purifier.

[0003] At present, the air outlets of most air purifiers are fixed grille-like structures, whose main function is to guide the clean air in the air duct of the air purifier to the local space outside the machine. Some purifiers are also equipped with manually or electronically adjustable air outlet grille structures, whose main function is to change the direction of the clean air outlet so that the clean air is blown directionally to a fixed direction. The main defects of these air outlets are the narrow air outlet range and the unadjustable air outlet speed. The purifier can only purify a small local space in the room. Therefore, its practicality is insufficient and needs to be improved. Utility Model Content

[0028] The embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device by providing a two-way air adjustment structure for the air outlet of the air purifier. When the rotating handle is rotated to the right, the first swing blade and the second swing blade open outward at an angle. When the angle is the same as or proportional to the angle of the rotating handle, the air outlet range of the air outlet frame will be increased, the coverage of clean air will be wider, and the wind speed and noise of the air outlet will be reduced. When the rotating handle is rotated to the left, the first swing blade and the second swing blade shrink inward in an eight-shaped shape. The wind speed of the air outlet of the air outlet frame is reduced by the action of the eight-shaped swing blades. The air is accelerated, and the wind speed at the air outlet is higher, so that the clean air is blown faster and farther. Under the action of the Coanda effect, the clean air at the air outlet quickly reaches various angles of the ceiling and four walls in the room, meeting the needs of whole-house purification. By setting sponge slots and adjusting columns on the rotating handle, the adjusting columns can play an automatic damping effect inside the sponge slots, and then can control specific angles such as expansion or contraction of 10°, 20°, 30°, 45°, etc. on both sides. By adjusting and changing the air outlet range, the air outlet speed and noise of the purifier can be optimized, thereby further improving practicality.

[0029] Example

[0030] like Figure 1 - Figure 6 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient practicality of the existing device. The overall idea is as follows:

[0031] In view of the problems existing in the prior art, the present invention provides a two-way air adjustment structure for the air outlet of an air purifier, comprising a rear shell assembly 11, an air outlet frame 18 is provided at the upper end of the rear shell assembly 11, and an empty slot 19 is provided inside the air outlet frame 18;

[0032] The empty slots 19 are each provided with a two-way air regulating structure;

[0033] The two-way air adjustment structure includes a first air outlet area 21 and a second air outlet area 22. A plurality of first fixed columns 23 are fixedly installed inside the first air outlet area 21. A plurality of first swing blades 25 are rotatably installed on the circumferential surface of each first fixed column 23. A plurality of second fixed columns 24 are fixedly installed inside the second air outlet area 22. A second swing blade 26 is rotatably installed on the circumferential surface of each second fixed column 24. A third fixed column 27 is fixedly installed inside the empty slot 19. A rotating handle 28 is rotatably installed on the circumferential surface of the third fixed column 27. The rotating handle 28 is located between the first swing blade 25 and the second swing blade 26. An adjusting column 29 is provided inside the rotating handle 28. A sponge slot hole 31 is provided on the inner wall of the empty slot 19. The adjusting column 29 is located inside the sponge slot hole 31. By setting the sponge slot hole 31, an adjusting column is provided on the rotating handle 28 29, so that the adjustment column 29 can play an automatic damping effect inside the sponge slot 31, and then can control the specific angles such as expansion or contraction of 10°, 20°, 30°, 45° on both sides. By adjusting the air outlet range, the air outlet speed and noise of the purifier can be optimized, and the practicality is further improved. For example, when in a low gear, the user can retract the first pendulum blade 25 and the second pendulum blade 26 inward in an "eight" shape to increase the wind speed of the air outlet, so that the wind speed of the air outlet frame 18 can quickly reach the ceiling and walls, so that the clean air can quickly reach every corner of the room, meeting the needs of whole-house purification. When in a high gear, the user can expand the first pendulum blade 25 and the second pendulum blade 26 outward, so that the wind speed of the air outlet is reduced, the air outlet range is wider, the purification range is increased, and the noise is also reduced.

[0034] The inner wall of the empty slot 19 is respectively rotatably mounted with a driven gear 32 and a driving gear 33, the driven gear 32 is meshed with the driving gear 33, and the circumferential surface of the driving gear 33 is provided with a first special-shaped connecting piece 34. The circumferential surface of the third fixed column 27 is fixedly mounted with a gear body 41, the gear body 41 is located below the driving gear 33, the gear body 41 is meshed with the driving gear 33, and the circumferential surface of the driven gear 32 is provided with a second special-shaped connecting piece 35. A first connecting rod 36 is provided between each first swing leaf 25. When the handle 28 is rotated, the rotation of the handle 28 will drive the gear body 41 to mesh with the driving gear 33, thereby generating a radial force on the first special-shaped connecting piece 34. At the same time, the driving gear 33 will rotate at a certain angle and mesh with the driven gear 32. When the first special-shaped connecting piece 34 rotates, the second special-shaped connecting piece 35 is fixedly mounted on the circumferential surface of the third fixed column 27. A special-shaped connecting member 34 will generate a radial force on the second connecting rod 37, thereby controlling each second pendulum blade 26 to rotate around the second fixed column 24 as the center of the circle. When the first special-shaped connecting member 34 moves, the first special-shaped connecting member 34 will drive the driving gear 33 to engage with the driven gear 32, thereby causing the driven gear 32 to generate a radial force on the first connecting rod 36. Since the first connecting rod 36 and the first pendulum blade 25 inside the first air outlet area 21 are in a state of interlocking, each first pendulum blade 25 will rotate around the first fixed column 23 as the center of the circle, thereby completing the synchronous wind direction adjustment of the first pendulum blade 25 and the second pendulum blade 26, so that each first pendulum blade 25 and the second pendulum blade 26 are respectively contracted or opened in an eight-shaped state, thereby achieving the effect of adjusting and changing the air outlet range to expand or accelerate the contraction of the air outlet, thereby improving practicality.

[0035] A second connecting rod 37 is provided between each second swing blade 26, each first connecting rod 36 is interlocked with the first swing blade 25, and each second connecting rod 37 is interlocked with the second swing blade 26. A first through slot 38 is provided inside the first connecting rod 36, and a second through slot 39 is provided inside the second connecting rod 37. Part of the first special-shaped connecting piece 34 is located inside the second through slot 39, and part of the second special-shaped connecting piece 35 is located inside the first through slot 38. A motor wind wheel assembly 12 is provided inside the rear shell assembly 11, and a motor body 13 is provided inside the motor wind wheel assembly 12. A middle frame 14 is provided on the side wall of the rear shell assembly 11, and a volute air duct 15 is provided on the side wall of the middle frame 14. The volute air duct 15 is on the same side as the motor body 13, a filter 16 is provided inside the middle frame 14, and an air inlet grille 17 is provided on the side wall of the middle frame 14 away from the volute air duct 15.

[0036] Working principle:

[0037] In the first step, when the user needs to adjust the air outlet direction of the empty slot 19, the user can rotate the rotating handle 28, so that the rotating handle 28 (the rotation angle is generally 30-45 degrees on both sides) generates a radial force to drive the adjustment column 29 to slide inside the sponge slot 31, so that the sponge inside the sponge slot 31 is squeezed, thereby controlling the adjustment column 29 to rotate. At this time, the rotation of the rotating handle 28 will drive the gear body 41 to engage with the driving gear 33, thereby generating a radial force on the first special-shaped connecting member 34. At the same time, the driving gear 33 will rotate at a certain angle and engage with the driven gear 32 for transmission;

[0038] In the second step, when the first special-shaped connecting member 34 rotates, the first special-shaped connecting member 34 will generate a radial force on the second connecting rod 37. Since the second connecting rod 37 and the second pendulum blade 26 inside the second air outlet area 22 are in a state of being interlocked, the second connecting rod 37 will generate a radial force to drive each second pendulum blade 26 to rotate around the second fixed column 24 as the center of the circle, thereby completing the air outlet angle adjustment of the second pendulum blade 26. When the first special-shaped connecting member 34 moves, the first special-shaped connecting member 34 will drive the driving gear 33 to engage with the driven gear 32, thereby causing the driven gear 32 to generate a radial force on the first connecting rod 36. Since the first connecting rod 36 and the first pendulum blade 25 inside the first air outlet area 21 are in a state of being interlocked, each first pendulum blade 25 will rotate with the first fixed column 23 as the center of the circle, thereby completing the synchronous wind direction adjustment of the first pendulum blade 25 and the second pendulum blade 26.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
