[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] A type of air purifier, please refer to Figure 1-8As shown, it includes: a main unit 100, a base 200, a filter holder 300, and a filter 400, with the filter holder 300 connected between the main unit 100 and the base 200.

[0036] like Figure 2 and Figure 4 As shown, the filter screen 400 has a first support 500 at its first end and a second support 600 at its second end.

[0037] The filter 400 can be compressed into a square shape or deformed into a cylindrical shape. During transportation, the filter 400 can be compressed into a square shape for easy transport. When in use, the first end and the second end of the filter 400 can be connected by the first bracket 500 and the second bracket 600 to make the filter 400 cylindrical, which is suitable for use in air purifiers.

[0038] There are multiple ways to connect the first bracket 500 and the second bracket 600, as long as it is convenient to connect and separate the two. One way to connect them is that one of the first bracket 500 and the second bracket 600 is provided with a latch and the other is provided with a locking groove. The latch and the locking groove cooperate to allow the first bracket 500 and the second bracket 600 to be quickly connected and separated.

[0039] In one implementation, such as Figure 3 As shown, a portion of the bottom surface of the main unit 100, a portion of the top surface of the base 200, and the outer side of the filter support 300 together form an installation groove 700. The opening of the installation groove 700 is opposite to the outer side of the filter support 300, so that the installation groove 700 is open, which makes it easy for the filter 400 to be installed in the installation groove 700 from the side.

[0040] After the filter screen 400 is assembled into the mounting groove 700, the filter screen 400 surrounds the filter screen bracket 300, and the first end and the second end of the filter screen 400 are connected and locked by the latches and locking grooves provided on the first bracket 500 and the second bracket 600.

[0041] In this embodiment, the filter 400 is mounted on the mounting groove 700 from the periphery of the purifier, which facilitates the installation and removal of the filter 400. After the purifier has been used for a period of time, the filter 400 can be quickly replaced or the filter 400 can be quickly removed and cleaned.

[0042] Furthermore, in this embodiment, the filter support 300 is cylindrical, and the filter 400, after surrounding the filter support 300, is also cylindrical. Correspondingly, the mounting groove 700 is arranged in a ring shape.

[0043] Alternatively, the filter holder 300 can be changed to a rectangle. Then, after the filter 400 surrounds the filter holder 300, the filter 400 will also be rectangular. Correspondingly, the shape of the mounting groove 700 will also be modified accordingly.

[0044] In this embodiment, as Figure 3 As shown, the upper end of the filter support 300 is connected to the bottom surface of the main unit 100, and the outer edge of the bottom surface to the connection between the bottom surface and the upper end of the filter support 300 forms a first groove surface; the lower end of the filter support 300 is connected to the top surface of the base 200, and the outer edge of the top surface to the connection between the top surface and the lower end of the filter support 300 forms a second groove surface 201; the first groove surface, the outer surface of the filter support 300, and the second groove surface 201 together form an installation groove 700.

[0045] After the filter screen 400 is installed in the mounting groove 700, the upper end of the filter screen 400 is connected to the first groove surface, and the lower end of the filter screen 400 is connected to the second groove surface 201.

[0046] like Figure 2 and Figure 3 As shown, the thickness of the filter 400 and the depth of the mounting groove 700 should be the same or approximately the same, so that after the filter 400 is installed in the mounting groove 700, the curvature of the entire purifier is smooth, effectively improving the aesthetics of the purifier's appearance.

[0047] In one embodiment, the filter 400 is formed with a plurality of pleats 401.

[0048] like Figure 4 As shown, the filter screen 400 is formed by repeatedly folding the filter material to create pleats 401. Because the filter screen 400 has pleats 401, it can deform.

[0049] Continue as Figure 4 As shown, the filter 400 can be stretched into a roughly rectangular shape, or the first and second ends of the filter 400 can be moved toward each other to compress it. After compression, it can be packaged, making the filter 400 smaller in volume and easier to store and transport.

[0050] During installation, the filter screen 400 is deformed. Figure 5 The shape shown, and as Figure 2 As shown, the filter 400 is assembled from the side of the purifier into the mounting groove 700, and finally the first end and the second end of the filter 400 are connected and closed by the first bracket 500 and the second bracket 600.

[0051] In one implementation, such as Figure 4The lengths of the first bracket 500 and the second bracket 600 shown are the same as the width of the filter screen 400; the first bracket 500 is glued and fixed to the first end of the filter screen 400, and the second bracket 600 is glued and fixed to the second end of the filter screen 400.

[0052] The first bracket 500 and the second bracket 600 are fixed to the filter screen 400 by adhesive, which is simple to install and not easy to fall off;

[0053] The lengths of the first support 500 and the second support 600 are the same as the width of the filter screen 400, such as... Figure 3 As shown, after the first bracket 500 and the second bracket 600 are connected, the first bracket 500 and the second bracket 600 provide certain support for the filter screen 400 in the vertical direction, making it less likely for the cylindrical filter screen 400 to deform in the vertical direction.

[0054] In one embodiment, the first bracket 500 is provided with a locking groove 510, and the second bracket 600 is provided with a latch 610; the first bracket 500 is provided with a protrusion 520, and the second bracket 600 is provided with a groove 620, and when the latch 610 is engaged in the locking groove 510, the protrusion 520 is engaged in the groove 620.

[0055] like Figure 5 and Figure 6 As shown, after the filter screen 400 is shaped into a cylindrical shape, the side where the first support 500 and the second support 600 meet is the outer side; the outer side of the first support 500 is provided with a protrusion 520, and the outer side of the second support 600 is provided with a groove 620.

[0056] like Figure 8 As shown, the cross-section of the latch 610 is T-shaped.

[0057] like Figure 6 As shown, the opening 513 of the lock groove 510 is relatively large, which facilitates the guidance of the latch 610 into the groove.

[0058] During installation, if the first bracket 500 is defined as fixed, then the second bracket 600 will move along... Figure 8 When the arrow indicates that the first bracket 500 is slidably assembled, the protrusion 520 slides into the groove 620, and the latch 610 slides into the locking groove 510.

[0059] The aforementioned protrusion 520 and groove 620 are auxiliary positioning features, allowing the latch 510 to smoothly enter the locking groove 610.

[0060] Furthermore, such as Figure 8 As shown, the latch 610 has a first latching part 611 and a second latching part 612. The second latching part 612 is vertically mounted on the bottom of the first latching part 611, and the diameter of the second latching part 612 is smaller than the diameter of the first latching part 611.

[0061] like Figure 6 As shown, the locking groove 510 is formed with a first storage position 511 for receiving the first buckle 611 and a second storage position 512 for receiving the second buckle 612. Before entering the second storage position 512, the second buckle 612 passes through a neck 514. The diameter of the neck 514 is slightly smaller than the diameter of the second buckle 612. When the second buckle 612 enters the neck 514, the neck 514 slightly deforms and expands. After the second buckle 612 enters the second storage position 512, the neck 514 returns to its original position to prevent the second buckle 612 from exiting the second storage position 512, so that the connection between the first bracket 500 and the second bracket 600 is more stable.

[0062] During dismantling, the first support 500 is defined as fixed and stationary, along... Figure 8 Pull the second bracket 600 in the opposite direction as indicated by the arrow, pull the latch 610 out of the locking groove 510, and the first bracket 500 and the second bracket 600 can be separated. Then the filter screen 400 can be removed.

[0063] like Figure 5 As shown, the first bracket 500 has two locking grooves 510 distributed vertically, and the second bracket 600 has two locking buckles 610 distributed vertically.

[0064] Optionally, the number of lock slots 510 and latches 610 can be adapted.

[0065] In one embodiment, in order to facilitate the separation of the first bracket 500 and the second bracket 600 and to quickly remove the filter screen 400, the first bracket 500 is provided with a pressing part 530 and the second bracket 600 is provided with a handle 630.

[0066] like Figure 5 As shown, a pressing part 530 is provided near the upper locking groove 510 of the first bracket 500; the pressing part 530 can be a circular protrusion, or a mark set on the first bracket 500, etc., mainly to inform the user where to press to facilitate the removal of the filter screen 400.

[0067] The second support 600 is provided with a handle position 630 at approximately the middle position. The handle position 630 protrudes towards the first support 500, and the first support 500 is provided with a notch 501 corresponding to the handle position 630.

[0068] When removing the filter 400, the user presses the pressing part 530 inward with one hand and pulls the gripping tendon 630 outward with the other hand to pull the lock 610 out of the lock groove 510. After the first bracket 500 and the second bracket 200 are separated, the filter 400 can be taken out.

[0069] In one implementation, such as Figure 1 and Figure 3As shown, the filter 400 is covered with a cloth cover 800. The cloth cover 800 has good air permeability. Air passes through the cloth cover 800 and then through the filter 400. The cloth cover 800 isolates large particles of dust and hair from the outside, which can extend the life of the filter 400.

[0070] To make the cloth cover 800 fit more stably over the filter screen 400, elastic bands can be provided at both the upper and lower ends of the cloth cover 800.

[0071] In one embodiment, the filter support 300 is hollow to form a cavity, and the side wall of the filter support 300 is provided with a through hole 310, through which the cavity is connected to the mounting groove 700.

[0072] In this embodiment, the through hole 310 is set as a hexagon;

[0073] Alternatively, the through hole 310 can be configured with other shapes.

[0074] The through holes 310 are filled as completely as possible with the filter support 300.

[0075] In one embodiment, the host 100 is provided with a wind system, and the host 100 is provided with an air outlet 110 and an air inlet communicating with the cavity.

[0076] Here, the wind power system uses technology known to those skilled in the art, which can drive air flow; when the wind power system is running, the air outside the purifier flows through the cloth cover 800, filter 400, through hole 310, cavity, air inlet, inside the main unit 100, and air outlet 110 in sequence.

[0077] During this process, the air undergoes a first filtration when it flows through the cloth cover 800, filtering out hair, large dust particles, etc. The air then undergoes a second filtration when it flows through the filter screen 400. The effectiveness of the second filtration depends on the specific material of the filter screen 400, which is not limited here. For example, commonly used materials for the filter screen 400 include fiber filter elements, particulate filter elements, HEPA filter elements, etc.

[0078] The purified air enters the cavity, then flows through the air inlet and the inside of the main unit 100, and finally is discharged from the air outlet 110.

[0079] Inside the main body 100, an air duct can be formed between the air inlet and the air outlet 110.

[0080] like Figure 1 As shown, the main unit 100 is provided with an operation panel 120 on the top to control the operation of the purifier; the operation panel 120 can be a button panel or a touch panel, and the operation of the fan system can be controlled through the operation panel 120.

[0081] In addition, the main unit 100 should also be equipped with electronic boards and other structures. Here, no specific restrictions are made on the specific electrical connection methods of the various electrical components inside the main unit 100.

[0082] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

[0083] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
