For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] See Figures 1 to 3 This utility model discloses an air purifier with a filter box, comprising: an electrical body 100, wherein the electrical body 100 is provided with a fan 200 and a filter element 300; a filter box 400 disposed in the electrical body 100, the filter box 400 having an air inlet channel 401 with an opening facing downward, the filter box 400 having a collection chamber 402 communicating with the air inlet channel 401 inside, and the filter box 400 having a plurality of vent holes 403 communicating with the collection chamber 402; wherein, the fan 200 drives external fluid to pass sequentially through the air inlet channel 401, the collection chamber 402 and the vent holes 403 and then through the filter element 300, so that hair in the external fluid is retained in the collection chamber 402.

[0024] The air purifier with the above structure has a filter box 400 at the front end of the fluid's direction of travel. The opening of the air intake channel 401 faces downwards toward the ground. Under the suction of the fan 200, hair on the ground is drawn into the air intake channel 401 along with the surrounding air. The gas in the fluid entering the filter box 400 then passes through the vent 403 to reach the filter element 300, while the hair is collected in the collection chamber 402. This prevents hair from adhering to the surface of the filter element 300 and causing cleaning difficulties, reduces the impact of air resistance on the filtration effect, and extends the service life of the filter element 300. It should be noted that the vent can be at least one of round, square, or oblong holes. The diameter of the vent is not limited to a specific range and can be set based on actual testing, generally between 2mm and 10mm.

[0025] See Figure 3 In some embodiments of this utility model, the filter box 400 is internally provided with two upwardly extending air inlet wall plates 410, which define the air inlet channel 401. At least one of the air inlet wall plates 410 has an arc-shaped guide section 420 at its upper end that can guide the fluid flow to the collection chamber 402. It can be understood that the fluid entering from the air inlet channel 401 flows upward and flows towards the side of the collection chamber 402 under the wall adhesion effect of the arc-shaped guide section 420. When the fan 200 is working, it drives the gas in the collection chamber 402 to flow to the filter element 300 through the vent 403. A negative pressure is formed in the collection chamber 402, thereby improving the efficiency of the fluid entering the collection chamber 402 from the air inlet channel 401 and reducing gas turbulence.

[0026] See Figure 3 In some embodiments of this utility model, a collection chamber 402 is defined between the two sections of the air intake wall panel 410 and the inner wall of the filter box 400. The two collection chambers 402 are arranged opposite to each other on both sides of the air intake channel 401. The upper ends of the two sections of the air intake wall panel 410 are each provided with an arc-shaped guide section 420. The two arc-shaped guide sections 420 respectively guide two streams of fluid to generate swirling motions in different clockwise directions. It can be understood that when the fan 200 is working, it will create a negative pressure in the two collection chambers 402 on both sides of the air intake channel 401. The external fluid enters from the lower end of the air intake channel 401 and flows upward to the upper end of the air intake channel 401. Then, under the guiding action of the two arc-shaped guide sections 420, it is divided into two airflows that flow to the two collection chambers 402 respectively, forming the effect of one airflow rotating clockwise and the other airflow rotating counterclockwise. This is conducive to the entry of hair into the middle and lower parts of the collection chamber 402 and the collection of more hair.

[0027] See Figure 3In some embodiments of this utility model, a flow channel is formed between the arc-shaped guide section 420 and the inner top wall of the filter box 400. The flow channel is located in the upper-middle part of the height direction of the filter box 400. The collection chamber 402 is located below the flow channel and communicates with the flow channel. The wall panel of the filter box 400 corresponding to the flow channel is a solid plate. In this embodiment, the wall panel with vents 403 is a solid plate at the position corresponding to the flow channel, and the remaining positions are evenly covered with vents 403, which helps to reduce airflow resistance. The solid plate can also prevent hair from being attracted at the flow channel and unable to enter the collection chamber 402.

[0028] See Figure 3 In some embodiments of this utility model, the rectangular box is arranged along the horizontal direction. In order to increase the adsorption area on the ground, the lower ends of the two sections of the air intake wall panel 410 are connected to the flared extension plate 430. The two flared extension plates 430 are arranged opposite to each other to define a flared opening that communicates with the air intake channel 401.

[0029] See Figure 2 or Figure 4 In some embodiments of this utility model, a front panel 110 is detachably mounted on the front side of the electrical body 100. The filter box 400 has an inner surface facing the front panel 110 and a downward opening. The air intake wall panel 410 is formed on the filter box 400. The filter box 400 is detachably connected to the inner surface of the front panel 110 to define the air intake channel 401 and the collection chamber 402. It is understood that when it is necessary to clean the hair in the filter box 400, one only needs to remove the front panel 110 from the electrical body 100, and then remove the filter box 400 from the front panel 110 to pour out the hair. Cleaning is very convenient. The front panel 110 forms part of the collection chamber 402, which helps to reduce the number of parts.

[0030] See Figure 3 and Figure 4 In some embodiments of this utility model, the open edge of the filter box 400 has a U-shaped retaining edge 440, with the opening of the U-shaped retaining edge 440 facing downwards. The inner peripheral wall of the U-shaped retaining edge 440 and the inner surface of the front panel 110, as well as the side wall of the air intake wall panel 410 away from the air intake channel 401 and the inner surface of the front panel 110, are detachably connected by a snap-fit ​​assembly 500. This facilitates removal and ensures stable installation of the filter box 400 on the front panel 110. Furthermore, the air intake wall panel 410 is also constrained and less prone to deformation, thereby ensuring the shape stability of the air intake channel 401. Of course, in other embodiments, the snap-fit ​​assembly 500 can also be replaced by a magnetic assembly or other detachable structures.

[0031] See Figure 2 or Figure 4 In some embodiments of this utility model, the filter box 400, the filter element 300, and the fan 200 are arranged sequentially along the direction of external fluid flow. The filter box 400 is located at the lower part of the electrical body 100, and multiple vent holes 403 fill the sidewall of the collection chamber 402 facing the filter element 300. In some embodiments, the filter box 400, the filter element 300, and the fan 200 are arranged at intervals along a horizontal direction to reduce the number of fluid bends, which helps to reduce wind resistance and improve the efficiency of filtration and purification. The filter element 300 can be a HEPA filter, which can effectively capture particles larger than 0.3 micrometers, including dust, pollen, some bacteria, and viruses, through physical interception, and also has a certain adsorption capacity for most gaseous pollutants. Of course, in other embodiments, the filter element 300 can also be an electrostatic dust collection filter. Electrostatic dust collection filters do not require frequent filter replacement, have lower maintenance costs, and can also kill some bacteria and viruses.

[0032] See Figure 5 and Figure 6 In some embodiments of this utility model, the filter box 400 is detachably installed on the bottom wall of the electrical appliance body 100 to support the electrical appliance body 100 upwards. The output end of the air inlet channel 401 is upwardly positioned. The collection chamber 402 and the vent 403 are arranged around the outer periphery of the air inlet channel 401, and the vent 403 penetrates the bottom wall of the electrical appliance body 100 vertically. When it is necessary to clean hair from the filter box 400, the filter box 400 can be directly detached from the bottom of the electrical appliance body 100 without disassembling the outer shell of the electrical appliance body 100, making it more convenient to use.

[0033] See Figure 6In some embodiments of this utility model, the electrical body 100 includes a cylindrical outer shell 120, the filter element 300 is a cylindrical filter element disposed inside the cylindrical outer shell 120, the outer peripheral wall of the cylindrical filter element and the inner peripheral wall of the cylindrical outer shell 120 define an air inlet chamber 130 communicating with the vent 403, the internal channel of the cylindrical filter element forms an exhaust chamber 140, the filter box 400 includes a cylindrical base 450, the middle of the cylindrical base 450 is provided with an outer horn pipe 460 which is wider at the bottom and narrower at the top and an inner horn pipe 470 which are coaxially arranged, the outer horn pipe 460 and the inner horn pipe 470 define the air inlet channel 401, and the upper edge of the outer horn pipe 460 is provided with an annular flange 461 that guides the fluid to the collection chamber 402. The cylindrical outer shell 120 has multiple air inlets on its outer peripheral wall. The air inlet channel 401 of the filter box 400 can adsorb hair and air near the ground, while the air inlets on the cylindrical outer shell 120 are used to draw in air at a certain distance from the ground, thus efficiently achieving the functions of cleaning hair and debris and purifying the air. The air inlet channel 401, formed by the outer horn pipe 460 and the inner horn pipe 470, can achieve a larger flow rate and adsorb hair over a large area. After being discharged from the upper end of the air inlet channel 401, the hair and debris are guided by the annular flange 461 into the annular collection chamber 402 on the outer periphery. The hair and debris fall downwards, while the gas continues to flow upwards to enter the air inlet chamber 130, and then passes through the exhaust chamber 140 and the fan 200 to be discharged upwards.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
