Description

Technical Field

[0001] This utility model relates to the field of air purification technology, specifically to an air intake reversing mechanism and an air purification device containing the mechanism. Background Technology

[0002] Air purifiers, also known as air cleaners or air fresheners, are products that can adsorb, decompose, or transform various air pollutants, generally including dust, pollen, odors, bacteria, allergens, and indoor air pollution such as formaldehyde, effectively improving air cleanliness. They are mainly household and commercial air purifiers used to remove indoor air pollution.

[0003] Currently, household air purifiers, due to their fixed air intake positions, can only draw air from one side into the internal filter for purification, resulting in relatively low efficiency in purifying air from other directions.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an air intake reversing mechanism and an air purification device containing the mechanism. Utility Model Content

[0005] The purpose of this invention is to provide an air intake reversing mechanism and an air purification device containing the mechanism, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an air intake reversing mechanism, including an air intake seat and a reversing plate. A protective cover is disposed at the center of the bottom of the air intake seat, and a servo motor is fixed on one side of the protective cover. The output shaft of the servo motor is connected to a drive gear, and one end of the drive gear meshes with a driven gear. A transmission assembly is disposed on the top of the driven gear, and a central tube is connected inside the transmission assembly. A connecting pipe is fixed on the top of the central tube, and one end of the connecting pipe is connected to the reversing plate. A filter plate is disposed on one side of the reversing plate.

[0007] Furthermore, the interior of the commutator plate is hollow and is connected to the interior of the central tube via a connecting pipe.

[0008] Furthermore, the transmission assembly includes a first gear ring, a second gear ring, and a limiting seat. The first gear ring is mounted on the top of the driven gear, and the second gear ring is positioned above the first gear ring. The limiting seat is fixed to the top of the second gear ring.

[0009] Furthermore, the limiting seat is slidably connected to the central tube, and the central tube is rotatably connected to the air intake seat.

[0010] Furthermore, the transmission assembly also includes a compression spring and a limiting ring, with the top of the limiting seat abutting against the compression spring, and the top of the compression spring abutting against the limiting ring.

[0011] Furthermore, the driven gear is rotatably connected to the central tube, and the central tube is fixedly connected to the limiting ring.

[0012] Furthermore, the transmission assembly also includes a slider and a guide groove. The slider is fixed inside the limiting ring, and a guide groove is provided on the outside of the central tube. The slider is slidably connected to the central tube through the guide groove.

[0013] An air purification device is provided, wherein the air purification device is equipped with an air intake reversing mechanism as described above.

[0014] This utility model provides an air intake reversing mechanism and an air purification device containing the mechanism, which has the following beneficial effects: 1. This utility model, through the setting of the reversing plate, when the fan inside the air purification equipment works and creates a negative pressure at its upper end, external air will enter the reversing plate through the filter plate, and then enter the air purification equipment through the connecting pipe and the central pipe. When it is necessary to change the air intake direction, the servo motor can be started, which drives the central pipe to rotate through the active gear, driven gear and transmission components, thereby adjusting the position of the reversing plate, thereby drawing and purifying air from different directions, which helps to improve the purification efficiency of the air purification equipment. 2. Through the setting of the transmission component, this utility model allows the second gear ring teeth to move upward under the guidance of the inclined surface when an object accidentally obstructs the movement of the reversing plate during the reversing adjustment process. This compresses the spring to avoid obstruction, thus automatically disconnecting the transmission between the first and second gear rings. This prevents the connecting pipe from bending and breaking due to excessive resistance, further improving safety during use. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0018] like Figures 1 to 3 As shown, an air intake reversing mechanism includes an air intake seat 1 and a reversing plate 9. A protective cover 2 is installed at the center of the bottom of the air intake seat 1, and a servo motor 3 is fixed on one side of the protective cover 2. The gear is protected by the protective cover 2. The output shaft of the servo motor 3 is connected to a drive gear 4, and a driven gear 5 is meshed at one end of the drive gear 4. A transmission component 6 is provided on the top of the driven gear 5, and a central tube 7 is connected inside the transmission component 6. The servo motor 3 drives the central tube 7 to rotate through the drive gear 4, the driven gear 5, and the transmission component 6, thereby enabling the suction and purification of air from different directions. A connecting pipe 8 is fixed on the top of the central tube 7, and a reversing plate 9 is connected to one end of the connecting pipe 8. A filter plate 10 is provided on one side of the reversing plate 9. The interior of the reversing plate 9 is hollow and is connected to the interior of the central tube 7 through the connecting pipe 8. External air enters the reversing plate 9 through the filter plate 10, and then enters the air purification equipment through the connecting pipe 8 and the central tube 7.

[0019] like Figure 3 and Figure 4 As shown, the transmission assembly 6 includes a first gear ring 601, a second gear ring 602, and a limiting seat 603. The first gear ring 601 is mounted on the top of the driven gear 5, and the second gear ring 602 is positioned above the first gear ring 601. The limiting seat 603 is fixedly fixed to the top of the second gear ring 602. The limiting seat 603 is slidably connected to the central tube 7, and the central tube 7 is rotatably connected to the air intake seat 1. The central tube 7 can guide the limiting seat 603. The transmission assembly 6 also includes a compression spring 604 and a limiting ring 605. The top of the limiting seat 603 abuts against the compression spring 604, and the top of the compression spring 604 abuts against the limiting ring 605. The driven gear 5 is rotatably connected to the central tube 7, and the central tube 7 is fixedly connected to the limiting ring 605. The compression spring 604 pushes the limiting seat 603 under the limiting ring 605, so that the second gear ring 602 and the first gear ring 601 are in close contact, and transmission can be carried out. When the reversing plate 9 is accidentally blocked, the teeth of the second gear ring 602 will move upward under the guidance of the inclined surface, squeezing the compression spring 604, thus disconnecting the transmission between the first gear ring 601 and the second gear ring 602 and avoiding overload. The transmission assembly 6 also includes a slider 606 and a guide groove 607. The slider 606 is fixed inside the limiting ring 605, and the guide groove 607 is opened on the outside of the central tube 7. The slider 606 is slidably connected to the central tube 7 through the guide groove 607. When the limiting seat 603 rotates, the central tube 7 can be rotated through the slider 606.

[0020] An air purification device is provided, which is equipped with the above-mentioned air intake reversing mechanism. The air intake direction can be changed through the air intake reversing mechanism to improve the efficiency of indoor air purification, and it also has an overload protection function to improve the safety during use.

[0021] In summary, when using the air intake reversing mechanism and the air purification equipment containing the mechanism, the air intake seat 1 is first installed on the top of the air purification equipment housing. Then, when the fan inside the air purification equipment operates, creating a negative pressure at its upper interior, external air enters the reversing plate 9 through the filter plate 10, and then enters the air purification equipment through the connecting pipe 8 and the central pipe 7. Next, the servo motor 3 is started by the controller, causing it to drive the first gear ring 601 to rotate via the driving gear 4 and the driven gear 5. At this time, the compression spring 604 pushes the limiting seat 603 under the limiting ring 605, causing the second gear ring 602 to engage with the first gear ring 601. With the first gear ring 601 in close contact, when the first gear ring 601 rotates, the limit seat 603 can drive the central tube 7 to rotate via the slider 606, adjusting the position of the reversing plate 9. This allows for the suction and purification of air from different directions, improving the purification efficiency of the air purification equipment. Finally, when an object accidentally obstructs the movement of the reversing plate 9, the teeth of the second gear ring 602 will move upward under the guidance of the inclined surface, squeezing the compression spring 604. This disconnects the transmission between the first gear ring 601 and the second gear ring 602, preventing the connecting pipe 8 from bending and breaking due to excessive resistance, further improving safety during use.

Many modifications and variations will be apparent to those skilled in the art.
