DETAILED DESCRIPTION

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0037] An ultra-thin air purifier, see Figure 1-3 As shown, it includes: a housing 100, a fan 200 and a filter 300.

[0038] The housing 100 has a first chamber 101 and a second chamber 102 connected thereto. The second chamber 102 surrounds the outside of the first chamber 101. During assembly, the fan 200 is installed in the first chamber 101, and an air duct is formed between the inner wall of the first chamber 101 and the fan 200. The filter 300 is installed in the second chamber 102, and the filter 300 surrounds the outside of the fan 200. Figure 2As shown, when the fan 200 and the filter 300 are assembled, the fan 200 and the filter 300 are coaxially installed and radially distributed. The fan 200 is arranged in the annular space of the filter 300, and the air duct is also located in the annular space of the filter 300, which makes full use of the internal space of the filter 300, making the thickness of the air purifier host thinner, as shown in FIG. Figure 2 As shown, the arrow direction is the thickness direction of the air purifier host.

[0039] Continue as Figure 1 and Figure 2 As shown, an air inlet 114 is provided on the peripheral side of the housing 100 corresponding to the filter 300, and an air outlet 121 is provided on the front side of the housing 100 corresponding to the air outlet side of the fan 200;

[0040] like Figure 3 As shown, when the fan 200 is running, the external airflow flows from the air inlet 114 to the filter 300, and the filter 300 filters the airflow. The purified airflow enters the first chamber 101, that is, enters the air duct, and the fan 200 pushes the airflow in the air duct to flow out from the air outlet 121; the flow path of the airflow is as shown in FIG. Figure 3 As shown in the direction of the arrow, the air duct path is shorter and the thickness of the air purifier host is thinner.

[0041] In one embodiment, the housing 100 includes: a main body shell 110 and a filter cover 130, a partition 111 is arranged inside the main body shell 110, and the interior of the main body shell 110 is divided into a first chamber 101 and a second chamber 102 by the partition 111, a vent 1111 is arranged on the partition 111, and the first chamber 101 and the second chamber 102 are connected through the vent 1111; a panel 120 is arranged on the front side of the main body shell 110, the panel 120 corresponds to the first chamber 101, and the panel 120 has an air outlet 121; the filter cover 130 is installed on the front side of the main body shell 110 corresponding to the second chamber 102.

[0042] like Figure 1-2 As shown, the side defining the housing 100 and the bracket 400 is the back side (i.e. Figure 2 The right side), the other side is the front side (i.e. Figure 2 The openings of the second chamber 102 are all toward the front of the main body shell 110, and the filter screen 300 is disassembled and assembled from the front of the main body shell 110.

[0043] Furthermore, the main body shell 110 is composed of a panel 120, a back panel 112, a side panel 113 and a partition 111. The panel 120, the back panel 112, the side panel 113 and the partition 111 can be a split structure, and the four parts are independently manufactured and then assembled. Alternatively, the panel 120, the side panel 113 and the partition 111 can be an integrated structure, and the back panel 112 can be a detachable structure. When disassembling and assembling the fan 200, the back panel 112 is removed, and then the fan 200 is further disassembled, that is, the fan 200 is disassembled from the back side of the main body shell 110.

[0044] The side plate 113 is arranged in an arc shape, so the shape of the entire air purifier host is roughly a flat column, and the shape is close to the fan head style; the partition 111 is also roughly distributed in an arc shape, so the second chamber 102 is a circular cavity, and the filter 300 is also circular, such as Figure 1 As shown, during installation, the filter 300 is embedded in the second chamber 102 from the front, and the assembly is simple and fast. After the installation is completed, the filter cover 130 can be covered.

[0045] Optionally, the filter 300 may be a hepa filter with an annular structure.

[0046] Furthermore, the back plate 112 and the main body shell 110 , and the filter cover 130 and the main body shell 110 can be limited by snapping or locking with screws.

[0047] Furthermore, if Figure 1 As shown, air inlets 114 are arranged at multiple angles around the main body shell 110, and air flows in from multiple angles around the main body shell 110; specifically, the air inlets 114 are almost evenly distributed around the main body shell 110, and air flows in from multiple angles to ensure the air intake volume and enhance the air purification efficiency;

[0048] Correspondingly, a plurality of ventilation holes 1111 are evenly distributed around the partition 111 .

[0049] like Figure 2 As shown, the panel 120 is tilted outward from the middle to form an inclined surface 122. The inclined surface 122 is evenly provided with air outlets 121 around the central axis of the panel 120 at 360°. The central axis of the panel 120 overlaps with the central axis of the fan 200. Figure 2 As shown, the inclined surface 122 extends outward from the middle portion toward the back plate 112 of the main body shell 110; Figure 3 As shown, since the air outlets 121 are distributed on the inclined surface 122, the air flow diffuses outward when the air is discharged.

[0050] In one embodiment, the fan 200 is mounted on the panel 120 and located in the first chamber 101, and a first gap a is left between the peripheral side 201 of the fan 200 and the partition 111; a second gap b is left between the air inlet side 202 of the fan 200 and the back plate 112 of the main shell 110; Figure 2 and Figure 3 As shown, the first gap a and the second gap b are part of the air duct, which prevents the volume of the air duct from being too small and affecting the air intake, so that the airflow can smoothly enter the air intake side 202 of the fan 200.

[0051] Furthermore, combined Figure 1 and Figure 2 As shown, the air inlet 114 disposed on the peripheral side of the main body shell 110 is approximately opposite to the second gap b.

[0052] In one embodiment, a bracket 400 is installed on the back plate 112 of the housing 100; between the housing 100 and the bracket 400, one of them is provided with a limiting pin 410, and the other is provided with a slot 140, and an elastic limiting component 150 is provided corresponding to the slot 140; the limiting pin 410 is inserted into the slot 140 and is limited by the elastic limiting component 150, so that the bracket 400 is fixed to the housing 100;

[0053] like Figure 4 As shown, in this embodiment, the back plate 112 of the housing 100 is provided with a slot 140 , and the bracket 400 is provided with a limiting pin 410 .

[0054] like Figure 5-6 As shown, the elastic limiting component 150 includes: a spring 151 and a staple 152. The back plate 112 of the housing 100 forms a receiving cavity for accommodating the elastic limiting component 150. The receiving cavity is provided with a hole connected to the slot 140. The top of the staple 152 passes through the hole and extends into the slot 140. At the same time, the staple 152 is provided with a limiting portion 1521 to prevent the staple 152 from completely escaping from the receiving cavity and rebounding into the slot 140; the spring 151 is limited in the receiving cavity, and the spring 151 provides a force for the staple 152 to rebound into the slot 140; a circle of slots 411 are provided around the limiting pin 410. After the limiting pin 410 is inserted into the slot 140, the top of the staple 152 is snapped into the slot 411, as shown in FIG. Figure 6 As shown, the direction in which the limiting pin 410 is inserted into the slot 140 is perpendicular to the direction in which the clamp 152 is ejected into the slot 140 .

[0055] Furthermore, the top of the staple 152 is in an arc shape, and the inner wall of the slot 411 is in an arc shape. Figure 5 The limiting pin 410 can be inserted or pulled out relative to the slot 140 in the direction indicated by the arrow.

[0056] Furthermore, in order to make the assembly more stable, a plurality of groups of limiting pins 410 and elastic limiting components 150 are provided between the housing 100 and the bracket 400 .

[0057] like Figure 7-8 As shown, the bracket 400 can be designed to have an L-shaped cross section, which is a base bracket, or the bracket 400 can be designed to have a U-shaped cross section, which is a wall bracket; the L-shaped bracket 400 is used to place the air purifier on the ground or on a desktop, while the U-shaped bracket 400 is used to hang the air purifier on the wall. When the utility model product is sold, it can be equipped with both the L-shaped bracket 400 and the U-shaped bracket 400, and the user can selectively install and use them to meet different usage scenarios.

[0058] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be 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 will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
