An air purifier with switchable blowing modes

Abstract

This invention relates to an air purifier with switchable blowing modes, comprising a purifier body, a rectangular air outlet shell disposed on the front side of the purifier body, an air outlet mesh disposed on the front side of the air outlet shell, and guided by a combination of horizontal and vertical sliding grooves, and in conjunction with a slidable connecting component. When concentrated air supply is required, the front guide columns on both sides can be driven to move and converge along the horizontal sliding grooves, and the front guide columns can be connected and fixed to the connecting component, thereby changing the tilt angle of the two sets of air guide plates and adjusting the air outlet area and air volume. Of course, only the front guide column of one side of the air guide plate can be connected to the connecting component, thereby concentrating the airflow to one side. In addition, by sliding the connecting component left and right, the air outlet position can be adjusted, thereby enabling the device to switch between multiple modes such as concentrated air supply, unilateral air supply, and wide-angle diffusion to meet the purification needs of different scenarios.

Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and in particular to an air purifier with switchable blowing modes. Background Technology

[0002] An air purifier draws in air through the inlet, purifies it using filters and other components, and then exhausts the purified air through the outlet, thus achieving the purpose of air purification. Some types of air purifiers have an air guide near the outlet, which directs the purified air out, controlling the direction of the airflow.

[0003] Existing air guiding devices may have fixed airflow direction or adjustable air outlets, typically resembling air deflectors on an air conditioner, allowing for manual adjustment of the airflow angle. However, they cannot adjust the airflow area or location, resulting in limited functionality and failing to meet user needs. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes an air purifier with switchable blowing modes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An air purifier with switchable blowing modes includes a purifier body, a rectangular air outlet housing on the front side of the purifier body, an air outlet mesh on the front side of the air outlet housing, vertically arranged air guide plates on both the left and right sides inside the air outlet housing, a front guide post and a rear guide post on the front and rear edges of the air guide plates respectively, horizontal sliding grooves extending in the left and right directions spaced vertically on the front side wall inside the air outlet housing, and vertical sliding grooves extending in the front and rear directions spaced vertically on both the left and right side walls inside the air outlet housing, the upper and lower ends of the front guide post sliding in the horizontal sliding grooves, the upper and lower ends of the rear guide post sliding in the vertical sliding grooves, and a connecting component that can slide in the left and right directions is also provided inside the air outlet housing, the front guide post being detachably connected to the connecting component.

[0007] In some embodiments, a horizontally arranged partition is provided inside the air outlet housing, and a transverse sliding groove and a longitudinal sliding groove are respectively provided on the partition.

[0008] In some embodiments, a slide rail extending in the left-right direction is provided at the upper end of the air outlet housing, and a sliding seat slides within the slide rail. The connecting assembly includes a connecting shaft disposed on the sliding seat, a connecting plate disposed at the lower end of the connecting shaft, and a U-shaped groove symmetrically arranged on the outer wall of the connecting plate with the connecting shaft as the center. Limiting flanges are provided on both sides of the U-shaped groove. The front guide post can slide into the U-shaped groove along the transverse slide groove and be limited and fixed by the limiting flanges.

[0009] In some embodiments, the connecting disc has a disc-shaped structure, and multiple sets of U-shaped slots are arranged along the circumference, with each set of U-shaped slots having a different recess depth. The connecting shaft is rotatably mounted on the sliding seat, and a knob is provided at the upper end of the connecting shaft.

[0010] In some embodiments, a support base is provided at the lower end of the sliding seat, and positioning grooves corresponding to the number of U-shaped slots are evenly distributed along the circumference of the outer wall of the connecting shaft. An elastic sheet is provided on the support base, one end of the elastic sheet is fixedly provided on the support base, and the other end is provided with a V-shaped positioning part, which abuts against the positioning groove.

[0011] In some embodiments, baffles are provided on both the left and right sides of the upper end of the sliding seat. The baffles are located above the slide rail and are used to cover the slide rail.

[0012] In some embodiments, a deflector is provided on the front guide post, and a first sliding groove extending in the left-right direction is provided on the front side of the air outlet housing, and the deflector is slidably disposed on the first sliding groove.

[0013] In some embodiments, a transverse sliding device capable of driving the sliding seat to slide automatically along the slide rail is also provided inside the air outlet housing.

[0014] In some embodiments, the lateral sliding device includes a motor mounted on the air outlet housing, the output shaft of the motor being vertically downward and connected to a transverse plate, a guide post being provided at the lower end of the transverse plate, guide crossbars extending in the left-right direction being spaced apart in the air outlet housing, a sliding crossbeam sliding in the left-right direction being connected between the two guide crossbars, the sliding crossbeam being fixedly connected to a support base, a second sliding groove extending in the front-back direction being provided on the sliding crossbeam, and the guide post being provided in the second sliding groove.

[0015] In some embodiments, the motor is located at the upper end of the air outlet housing, and the upper end of the air outlet housing is provided with a protective shell for protecting the motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] Through the combined guidance of horizontal and vertical chutes, and with the assistance of slidable connecting components, when concentrated air supply is required, the front guide columns on both sides can be driven to move along the horizontal chutes and close together, connecting and fixing them with the connecting components. This changes the tilt angle of the two sets of air guide plates, thereby adjusting the air outlet area and air volume. Alternatively, the front guide column of only one side of the air guide plate can be connected to the connecting components, concentrating the airflow to one side. Furthermore, by sliding the connecting components left and right, the air outlet position can be adjusted, allowing the device to switch between multiple modes such as concentrated air supply, unilateral air supply, and wide-angle diffusion to meet the purification needs of different scenarios.

[0028] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0029] like Figures 1-10 An air purifier with switchable blowing modes is shown, comprising a purifier body 1, a rectangular air outlet housing 2 on the front side of the purifier body 1, an air outlet mesh 3 on the front side of the air outlet housing 2, vertically arranged air guide plates 4 on both the left and right sides inside the air outlet housing 2, a front guide post 5 and a rear guide post 6 respectively on the front and rear edges of the air guide plate 4, horizontal sliding grooves 7 extending in the left and right directions are arranged vertically at intervals on the front side wall inside the air outlet housing 2, and vertical sliding grooves 8 extending in the front and rear directions are arranged vertically at intervals on both the left and right side walls inside the air outlet housing 2, the upper and lower ends of the front guide post 5 slide in the horizontal sliding grooves 7, and the upper and lower ends of the rear guide post 6 slide in the vertical sliding grooves 8, and a connecting component that can slide in the left and right directions is also provided inside the air outlet housing 2, the front guide post 5 can be detachably connected to the connecting component.

[0030] Based on the above structure, through the combined guidance of the transverse slide 7 and the longitudinal slide 8, and in conjunction with the slidable connecting components, when concentrated air supply is required, the front guide columns 5 on both sides can be driven to move and converge along the transverse slide 7, and the front guide columns 5 can be connected and fixed with the connecting components, thereby changing the tilt angle of the two sets of air guide plates 4 and adjusting the air outlet area and air volume. Of course, only the front guide column 5 of one side of the air guide plate can be connected to the connecting components, so that the air can be concentrated and blown out on one side. In addition, by sliding the connecting components left and right, the air outlet position can be adjusted, thereby enabling the equipment to switch between multiple modes such as concentrated air supply, unilateral air supply, and wide-angle diffusion to meet the purification needs of different scenarios.

[0031] See Figure 3 , Figure 7 As shown, a horizontally arranged partition 21 is provided inside the air outlet housing 2. The transverse sliding groove 7 and the longitudinal sliding groove 8 on the upper side are respectively provided on the partition 21. By setting the partition 21, the air outlet housing 2 can be divided into two chambers. The lower chamber is used for ventilation, while the upper chamber is used to accommodate connecting components and other parts. At the same time, it can enhance the overall strength of the air outlet housing 2.

[0032] See Figure 6-Figure 8 , Figure 10As shown, a slide rail 31 extending in the left-right direction is provided at the upper end of the air outlet housing 2. A sliding seat 32 slides within the slide rail 31. The connecting assembly includes a connecting shaft 33 disposed on the sliding seat 32. A connecting plate 34 is provided at the lower end of the connecting shaft 33. A U-shaped groove 35 is symmetrically arranged on the outer wall of the connecting plate 34 with the connecting shaft 33 as the center. Limiting flanges 36 are provided on both sides of the U-shaped groove 35. The front guide post 5 can slide into the U-shaped groove 35 along the transverse slide groove 7 and be limited and fixed by the limiting flanges 36.

[0033] When the front guide rod 5 is connected to the connecting assembly, it slides along the transverse slide groove 7 and gets into the U-shaped slot 35 of the connecting plate 34. The front guide rod 5 can be limited and fixed by the limiting flange 36. When the sliding seat 32 slides in the slide rail 31, it can drive the connecting shaft 33, the connecting plate 34 and the front guide rod 5 to slide together. At the same time, the tilt angle of the guide plate 4 is adjusted, thereby adjusting the air outlet area and the air outlet position.

[0034] It should be noted that when the current guide rod 5 slides in the transverse slide groove 7, its rear guide rod 6 slides adaptively in the longitudinal slide groove 8, while the rear guide rod 6 always remains against the inner wall of the air outlet housing 2.

[0035] Furthermore, the connecting disc 34 has a disc-shaped structure, and multiple sets of U-shaped slots 35 are arranged along the circumference, with each set of U-shaped slots 35 having a different recess depth. The connecting shaft 33 is rotatably mounted on the sliding seat 32, and a knob 41 is provided at the upper end of the connecting shaft 33.

[0036] By rotating the connecting plate 34, it is possible to align the U-shaped slots 35 with different recessed depths with the front guide rod 5 and engage them; that is, when the front guide rods 5 on both sides are engaged with the U-shaped slots 35 with different recessed depths, the distance between the two front guide rods 5 can be adjusted (i.e., the distance between them). Figure 6 The distance between the middle and lower parts (D) was adjusted to control the air outlet area and meet the needs of different scenarios.

[0037] Furthermore, a support base 51 is provided at the lower end of the sliding seat 32, and positioning grooves 52 are evenly distributed along the circumference of the outer wall of the connecting shaft 33, corresponding to the number of U-shaped slots 35. An elastic sheet 53 is provided on the support base 51, one end of the elastic sheet 53 is fixedly provided on the support base 51, and the other end is provided with a V-shaped positioning part 54, which abuts against the positioning groove 52.

[0038] After the connecting plate 34 is rotated and adjusted, the V-shaped positioning part 54 on the elastic plate 53 can cooperate with the positioning groove 52 to provide positioning feedback function, while preventing the connecting shaft 33 from rotating accidentally and ensuring the stability of the air guide plate 4 after angle adjustment.

[0039] See Figure 1 , Figure 2 , Figure 4 As shown, baffles 60 are provided on both the left and right sides of the upper end of the sliding seat 32. The baffles 60 are located above the slide rail 31 and are used to cover the slide rail 31. Thus, the baffles 60 cover the upper part of the slide rail 31, effectively preventing dust from entering the slide rail and avoiding the sliding seat 32 from failing due to foreign objects, thereby extending the service life of the slide rail.

[0040] To facilitate the sliding of the front guide column 5 within the transverse slide groove 7, a lever 61 is provided on the front guide column 5, and a first slide groove 62 extending in the left-right direction is provided on the front side of the air outlet housing 2, with the lever 61 slidably disposed on the first slide groove 62.

[0041] In this invention, a transverse sliding device is also provided inside the air outlet housing 2, which can drive the sliding seat 32 to slide automatically along the slide rail 31.

[0042] Furthermore, the lateral sliding device includes a motor 91 mounted on the air outlet housing 2. The output shaft of the motor 91 is vertically downward and connected to a transverse plate 92. A guide post 93 is mounted at the lower end of the transverse plate 92. Guide crossbars 94 extending in the left-right direction are spaced apart in the air outlet housing 2. A sliding crossbeam 95 that slides in the left-right direction is connected between the two guide crossbars 94. The sliding crossbeam 95 is fixedly connected to the support base 51. A second sliding groove 96 extending in the front-back direction is mounted on the sliding crossbeam 95. The guide post 93 is located in the second sliding groove 96.

[0043] To facilitate the protection of the motor 91 and improve the overall appearance of the equipment, the motor 91 is located at the upper end of the air outlet housing 2, and the upper end of the air outlet housing 2 is provided with a protective shell 97 for protecting the motor 91.

[0044] The specific working principle of the transverse sliding device is as follows: the motor 91 drives the transverse plate 92 to rotate. Since the guide post 93 at the outer end of the transverse plate 92 is located in the second sliding groove 96 on the sliding beam 95, the sliding beam 95 can be moved along the guide bar 95 in the left and right direction. The sliding beam 95 is fixedly connected to the support seat 51, which in turn drives the connecting shaft 33, the connecting plate 34 and the sliding seat 32 to slide left and right, thereby realizing the automatic adjustment of the air outlet position.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
