[0059] The following specific implementation methods will further illustrate this application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0062] With the advancement of socioeconomic standards, people are paying increasing attention to their surroundings (e.g., work and living environments). For example, in environments where adhesive dispensing is performed in a closed room, indoor air pollution can exceed that of outdoor air, impacting human health and even causing cancer. While most existing air purifiers (e.g., negative ion generators) have a moderate air purification effect, they can also cause secondary contamination during use, resulting in poor purification effectiveness. Furthermore, negative ion generators use high-voltage discharge, which can be prone to malfunction and difficult to maintain, resulting in low maintenance efficiency.

[0063] One embodiment of the present application provides a purifier, comprising a base assembly, a filter element assembly, and a fan assembly. The base assembly is provided with an air inlet. The filter element assembly is mounted on the base assembly, and the filter element assembly includes a filter element provided with a first accommodating chamber. The fan assembly is connected to the filter element assembly and is located above the filter element assembly. The fan assembly is used to drive air to be sucked in from the air inlet and flow through the filter element, the first accommodating chamber, and the fan assembly in sequence, so that the air purified by the filter element is blown out through the fan assembly.

[0064] This application sucks polluted air into the filter element through the air inlet of the base assembly, purifies the air through the filter element, and blows the purified air out through the fan assembly. During the process of air purification by the filter element, no secondary pollution will occur, and the purification effect is good. In addition, the purifier has a simple structure and is easy to maintain.

[0065] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0066] Please also see Figures 1 to 4 One embodiment of the present application provides a purifier 100, which includes a base assembly 11, a filter element assembly 12 and a fan assembly 13. The base assembly 11 is provided with an air inlet 1110. The filter element assembly 12 is mounted on the base assembly 11, and the filter element assembly 12 includes a filter element 120 provided with a first accommodating chamber 1201. The fan assembly 13 is connected to the filter element assembly 12 and is located above the filter element assembly 12. The fan assembly 13 is used to drive air to be inhaled from the air inlet 1110 and flow through the filter element 120, the first accommodating chamber 1201 and the fan assembly 13 in sequence, so that the air purified by the filter element 120 is blown out through the fan assembly 13.

[0067] When the purifier 100 performs air purification, the fan assembly 13 drives the polluted air to pass through the air inlet 1110 of the base assembly 11, and flows through the filter element 120, the first accommodating chamber 1201 and the fan assembly 13 in sequence, so that the filter element 120 purifies the air, and the air purified by the filter element 120 is blown out through the fan assembly 13, avoiding the purified air from being polluted again, thereby improving the purification effect of the purifier 100.

[0068] In some embodiments of this application, see Figure 4 As shown, filter element 120 includes a protective layer 1202, a purification layer 1203, and a support layer 1204. Protective layer 1202 is disposed outside support layer 1204. Purification layer 1203 is located between protective layer 1202 and support layer 1204. Purification layer 1203 includes a material layer 12030 and a filter layer 12031. Material layer 12030 is disposed inside filter layer 12031 and is used to purify air.

[0069] In some embodiments of the present application, the protective layer 1202, the filter layer 12031, the material layer 12030 and the support layer 1204 can all be set as hollow cylinders, and the protective layer 1202, the filter layer 12031, the material layer 12030 and the support layer 1204 are nested in sequence from the outside to the inside.

[0070] In some embodiments of the present application, protective layer 1202 is disposed outside purification layer 1203. Protective layer 1202 is used to filter larger airborne particles, such as hair and pet dander. Protective layer 1202 also protects filter element 120, preventing deformation. For example, in some embodiments, protective layer 1202 may be a polypropylene air conditioning mesh comprising multiple meshes that prevent larger airborne particles from passing through protective layer 1202.

[0071] In some embodiments of the present application, the filter layer 12031 is disposed inside the protective layer 1202. When air is filtered by the protective layer 1202 and flows through the filter layer 12031, the filter layer 12031 can filter out tiny particles in the air, such as dust and pollen. For example, in some embodiments, the filter layer 12031 can be a low-resistance filter paper, which can filter out tiny particles in the air.

[0072] In some embodiments of the present application, material layer 12030 is disposed inside filter layer 12031. When air passes through protective layer 1202 and filter layer 12031, and then through material layer 12030, material layer 12030 is configured to absorb gaseous pollutants in the air and decompose the gaseous pollutants into inorganic salts and water. For example, in some embodiments, material layer 12030 may include materials such as permanganates, transition metal oxides, and catalysts. When air flows through material layer 12030, the materials in material layer 12030 undergo a peroxygen reduction reaction with gaseous pollutants in the air, decomposing the gaseous pollutants into inorganic salts and water.

[0073] In some embodiments of the present application, filter element 120 purifies polluted air into inorganic salts and water, thereby improving the purification effect of purifier 100 and preventing secondary contamination of the purified air. Filter element 120 can also effectively decompose odors that may develop during use, thereby extending the service life of filter element 120.

[0074] In some embodiments of the present application, the filter element assembly 12 further includes an upper end cover 121 and a lower end cover 122. The upper end cover 121 and the lower end cover 122 are respectively provided at both ends of the filter element 120.

[0075] In some embodiments of the present application, the upper end cover 121 and the lower end cover 122 are respectively used to fix the upper end surface and the lower end surface of the filter element 120, so that the filter element assembly 12 becomes a whole, which is convenient for disassembly and installation from the purifier 100, thereby improving the maintenance efficiency of the filter element assembly 12.

[0076] In some embodiments of the present application, the base assembly 11 includes a base 110 and a bottom shell 111. A first end of the bottom shell 111 is connected to the base 110 and is located above the base 110. A second end of the bottom shell 111 is connected to the fan assembly 13. The bottom shell 111 is provided with at least one air inlet 1110.

[0077] In some embodiments of the present application, since air density is correlated with altitude, the higher the altitude, the lower the air density. Therefore, by providing an air inlet 1110 on the bottom shell 111, air can be sucked into the purifier 100 from a lower position, preferentially purifying polluted air with high air density, thereby improving the purification efficiency of the purifier 100.

[0078] In some embodiments of the present application, the base assembly 11 further includes a first circuit board 112 and a second circuit board 113. The first circuit board 112 is disposed on the base 110. The first circuit board 112 is used to connect to a power source. The second circuit board 113 is disposed on the bottom housing 111. The first circuit board 112 is electrically connected to the second circuit board 113. The second circuit board 113 is electrically connected to the fan assembly 13.

[0079] In some embodiments of the present application, a second circuit board 113 is provided on the bottom shell 111, and the second circuit board 113 is electrically connected to the fan assembly 13. When the filter element assembly 12 is disassembled and assembled, the second circuit board 113 and the fan assembly 13 are powered off, and the filter element assembly 12 can be disassembled and assembled without removing the fan assembly 13, thereby improving the disassembly and maintenance efficiency of the filter element assembly 12.

[0080] In some embodiments of the present application, the fan assembly 13 includes a body 130, a fan 131, an air inlet grille 132, and a first top cover 133. The first end of the body 130 is connected to the first end of the air inlet grille 132, and the second end of the body 130 is connected to the first top cover 133. The second end of the air inlet grille is connected to the filter element assembly 12. The body 130 is provided with a second accommodating chamber 1301 and an air duct 1302. The fan 131 is accommodated in the second accommodating chamber 1301. The air duct 1302 is connected to the air inlet grille.

[0081] In some embodiments of the present application, the purifier 100 further includes a top cover assembly 14. The top cover assembly 14 is connected to the fan assembly 13. The top cover assembly 14 includes a second top cover 140. The second top cover 140 is provided with at least one air outlet 1401 for discharging purified air.

[0082] In some embodiments of the present application, by providing at least one air outlet 1401 on the top cover of the purifier 100, the fan assembly 13 can blow the purified air out from the at least one air outlet 1401, and at the same time reduce the flow rate of the purified air, thereby preventing air with a higher flow rate from being blown out to the user and affecting the user experience.

[0083] In some embodiments of this application, see Figure 5 As shown, the top cover assembly 14 also includes a sensor module 141, a display assembly 142, and a touch button 143. The second top cover 140 also has a groove 1402 and a stepped hole 1403. The sensor module 141 and touch button 143 are mounted within the groove 1402. The display assembly 142 is positioned within the stepped hole 1403 and engages with a step 1404 of the stepped hole 1403. For example, the display assembly 142 has a snap-fitting portion 1420, and the step 1404 has a snap-fitting slot 14040. The snap-fitting portion 1420 extends through the snap-fitting slot 14040 to engage the display assembly 142 with the step 1404.

[0084] In some embodiments of the present application, when the purifier 100 purifies air, the sensor module 141 is used to collect data about the air flowing through the air duct 1302. The display assembly 142 is used to display the data collected by the sensor module 141. The touch button 143 is used for user operation.

[0085] In some embodiments of the present application, the sensor module 141 may include sensors such as a temperature sensor (not shown), a humidity sensor (not shown), and a gas sensor module (not shown). For example, the gas sensor may be a semiconductor TVOC sensor module. During the air purification process of the purifier 100, the air purified by the filter core assembly 12 reaches the semiconductor TVOC sensor module, which can detect the concentration of TVOC harmful gases in the purified air.

[0086] In some embodiments of the present application, a display assembly 142 is provided on the top cover assembly 14, and data detected by the sensor module 141 is intuitively displayed on the display assembly 142, allowing users to quickly understand air quality conditions and improving the user experience. Furthermore, the display assembly 142 snaps onto the purifier 100, requiring no additional tools. The simple structure allows for quick assembly and disassembly and maintenance of the purifier 100.
