Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to a portable air purifier. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, and allergens), effectively improving air cleanliness. They are mainly divided into household, commercial, industrial, and building types.

[0003] However, existing households may have multiple smart home devices, which occupy a certain amount of storage space and require coordination during mobile use. Therefore, they do not meet the current needs. To address this, we propose a portable air purifier. Utility Model Content

[0004] This invention addresses the problem of air purifiers being immobile by providing a time-saving and labor-saving portable air purifier.

[0005] This utility model provides the following technical solution: a portable air purifier, including a purifier body, with multiple wheels and multiple legs arranged at the bottom of the purifier body. The wheels are vertically telescopic. The bottom of the purifier body has a recessed cavity for accommodating the wheels. The wheels are connected to the bottom of the cavity via an electric telescopic rod. The wheels are hinged to a fixed frame. A fixed plate is fixed to the end of the telescopic part of the electric telescopic rod. The fixed plate is connected to the fixed frame via a buffer assembly.

[0006] In some embodiments, the buffer assembly includes a connecting ear plate, a slide rod, a return spring, a connecting rod, and a sliding block. The connecting ear plate is fixed to the lower end face of the fixed plate. The two ends of the slide rod are respectively connected to the opposite connecting ear plates. The sliding block is provided with a sliding hole that mates with the slide rod. The sliding block is sleeved on the slide rod through the sliding hole. Two return springs are sleeved on the slide rod. The return springs are respectively located on the left and right sides of the sliding block, and the two ends of the return springs abut against the wall surface of the sliding block and the wall surface of the connecting ear plate, respectively. The two ends of the connecting rod are respectively hinged to the sliding block and the fixed frame.

[0007] In some embodiments, a plurality of buffer components are circumferentially spaced around the central axis of the fixed plate, and the slide bar is arranged radially along the fixed plate.

[0008] In some embodiments, the buffer assembly includes a guide rod, which is fixed to the bottom of the accommodating cavity. The fixing plate is provided with a guide hole that mates with the guide rod, and the guide rod is inserted into the guide hole.

[0009] In some embodiments, a limiting boss is provided at the end of the guide rod, and when the guide rod is inserted into the guide hole, the limiting boss is located on the outside of the fixing plate.

[0010] In some embodiments, the wheels and legs are arranged circumferentially around the central axis of the purifier body, and the wheels and legs are arranged in an alternating pattern.

[0011] In some embodiments, there are two electric telescopic rods, located on the left and right sides of the fixed plate, respectively.

[0012] Compared with the prior art, the advantages of this utility model are as follows: This device uses an electric telescopic rod to drive the rotating wheel to move vertically up and down. When the electric telescopic rod drives the rotating wheel to move vertically downward, the support legs leave the ground, thus enabling the purifier body to move. When the electric telescopic rod drives the rotating wheel to move vertically upward, the bottom of the support legs contacts the ground, achieving a fixed position for the purifier body and preventing it from moving, making the purifier body more stable. Moreover, the electric telescopic rod and rotating wheel only work when the purifier body moves, improving its service life. At the same time, the buffer component ensures that the rotating wheel does not cause the purifier body to shake due to the unstable road surface during operation, thus affecting the stability of the purifier body.

[0024] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0025] Please see Figure 1-3As shown in this embodiment: a portable air purifier includes a purifier body 1. The bottom of the purifier body 1 is provided with multiple rotating wheels 3 and multiple support legs 2. The rotating wheels 3 are vertically telescopic. The bottom of the purifier body 1 is recessed and has a receiving cavity 1.1 for accommodating the rotating wheels 3. The rotating wheels 3 are connected to the bottom of the receiving cavity 1.1 through an electric telescopic rod 5. The rotating wheels 3 are hinged to a fixed frame 4. The telescopic end of the electric telescopic rod 5 is fixed with a fixed plate 6. The fixed plate 6 is connected to the fixed frame 4 through a buffer assembly 7.

[0026] The electric telescopic rod 5 drives the rotating wheel 3 to move vertically up and down. When the electric telescopic rod 5 drives the rotating wheel 3 to move vertically downward, the support leg 2 leaves the ground, thus enabling the purifier body 1 to move. When the electric telescopic rod 5 drives the rotating wheel 3 to move vertically upward, the bottom of the support leg 2 contacts the ground, achieving a fixed position for the purifier body 1 and preventing it from moving. This makes the purifier body 1 more stable. Moreover, the electric telescopic rod 5 and the rotating wheel 3 only work when the purifier body 1 moves, thus improving its service life.

[0027] In some embodiments, such as Figures 3-4 As shown, the buffer assembly 7 includes a connecting ear plate 7.1, a slide rod 7.2, a return spring 7.3, a connecting rod 7.5, and a sliding block 7.4. The connecting ear plate 7.1 is fixed to the lower end face of the fixing plate 6. The two ends of the slide rod 7.2 are respectively connected to the opposite connecting ear plates 7.1. The sliding block 7.4 has a sliding hole 7.4.1 that mates with the slide rod 7.2. The sliding block 7.4 is sleeved on the slide rod 7.2 through the sliding hole 7.4.1. Two return springs 7.3 are sleeved on the slide rod 7.2. The return springs 7.3 are respectively located on the left and right sides of the sliding block 7.4. The two ends of the connecting rod 7.5 abut against the wall of the sliding block 7.4 and the wall of the connecting ear plate 7.1, respectively. The two ends of the connecting rod 7.5 are hinged to the sliding block 7.4 and the fixed frame 4, respectively. It should be noted that when the rotating wheel 3 is bumped, the rotating wheel 3 moves up and down in the vertical direction, thereby driving the fixed frame 4 to move up and down. Since the two ends of the connecting rod 7.5 are hinged to the sliding block 7.4 and the fixed frame 4, the sliding block 7.4 moves on the sliding rod 7.2. Since the left and right sides of the sliding block 7.4 abut against the return spring 7.3, the return spring 7.3 deforms, thereby achieving the buffering of the rotating wheel 3.

[0028] In some embodiments, such as Figure 3 As shown, multiple buffer components 7 are arranged circumferentially around the central axis of the fixed plate 6, and the slide rod 7.2 is arranged radially along the fixed plate 6. It should be noted that this allows the wheel frame to be buffered in all directions on the same plane, resulting in better buffering performance and a longer service life.

[0029] In some embodiments, such as Figure 3As shown, the buffer assembly 7 includes a guide rod 7.6, which is fixed to the bottom of the accommodating cavity 1.1. The fixing plate 6 is provided with a guide hole 6.1 that cooperates with the guide rod 7.6. The guide rod 7.6 is inserted into the guide hole 6.1. It should be noted that the cooperation between the guide rod 7.6 and the guide hole 6.1 makes the fixing frame 4 more stable during the up and down movement.

[0030] In some embodiments, such as Figure 3 As shown, the guide rod 7.6 has a limiting boss 7.6.1 at its end. When the guide rod 7.6 is inserted into the guide hole 6.1, the limiting boss 7.6.1 is located on the outside of the fixed plate 6. It should be noted that the setting of the limiting boss 7.6.1 limits the downward movement distance of the fixed plate 6 to a maximum distance, preventing the fixed plate 6 from continuing to move downward, thus making the overall operation of the equipment more stable.

[0031] In some embodiments, such as Figures 1-2 As shown, the rotating wheel 3 and the support leg 2 are arranged circumferentially around the central axis of the purifier body 1, and the rotating wheel 3 and the support leg 2 are arranged in an alternating manner. It should be noted that the rotating wheel 3 is more stable during movement, and the support leg 2 is more stable during operation.

[0032] In some embodiments, such as Figure 3 As shown, there are two electric telescopic rods 5, located on the left and right sides of the fixed plate 6 respectively. It should be noted that the two electric telescopic rods 5 are located on the left and right sides of the fixed plate 6 respectively, which makes the wheel 3 more stable during the up and down movement.

[0033] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
