Description

Technical Field

[0001] This application relates to the field of air purification equipment, and in particular to an air purifier. Background Technology

[0002] Air purifiers with heating functions typically consist of core components such as a contoured housing, a fan, a heating element, and a filtration system. Air is drawn into the purifier through the inlet and undergoes multi-stage filtration to achieve air purification. The heating element then activates, heating the purified air. Driven by the fan, the heated fresh air is evenly distributed through the outlet, satisfying indoor heating needs while ensuring improved air quality.

[0003] However, the PTC heating element commonly used in existing air purifiers, while capable of heating the air to some extent, has several drawbacks when applied to a circular air outlet channel: the heating effect is unevenly distributed across different areas of the channel, resulting in varying air resistance. This uneven heating and air resistance distribution directly affects the uniformity and stability of the airflow, thus reducing the overall performance of the air purifier.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0010] The purifier body includes an inner shell and an outer shell. The inner shell is located inside the outer shell and forms an air outlet channel between them. The cross-section of the air outlet channel is annular with the inner shell as the center.

[0011] The heating assembly includes a bracket and a heating wire. The bracket is fixed to the top of the inner shell, and the heating wire is fixedly connected to the bracket. It also includes several heating elements that are evenly distributed radially around the bracket. The heating elements are evenly distributed at the relative positions of the air outlet channel.

[0012] In some embodiments, the bracket includes a fixing frame and a heat-conducting ring. The fixing frame is fixedly connected to the inner shell, and the heat-conducting ring is fixed to the periphery of the fixing frame and forms a heating channel between the fixing frame and the outer shell. The heating channel is opposite to the air outlet channel and is interconnected with it. The heating wire is fixedly connected to the heat-conducting ring, and the heating wire is evenly distributed around the periphery of the heat-conducting ring.

[0014] In some embodiments, the heat-conducting rings and heating wires are arranged in groups, and at least two groups are provided, with each group of heat-conducting rings and heating wires arranged at intervals along the extension direction of the heating channel.

[0015] In some embodiments, the inner shell is cylindrical, and the inner shell, the air outlet channel, and the heating channel are arranged along the same axis.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Existing air purifiers typically use PTC heating elements, which can heat the air. However, when applied to an air outlet channel with a circular cross-section, there are issues with uneven heating of the air in different areas of the outlet channel and uneven distribution of air resistance, which in turn affects the uniformity and stability of the airflow.

[0034] To address the aforementioned technical problems, this embodiment provides an air purifier, see reference. Figures 1 to 4 As shown, Figure 1 This is a perspective view of the air purifier in the embodiments of this application. Figure 2 This is a top view of the air purifier in an embodiment of this application. Figure 3 yes Figure 2 Sectional view of section A in the middle. Figure 4 This is a perspective view of the heating component in an embodiment of this application.

[0035] The air purifier in this embodiment includes: a purifier body 1 and a heating component 2.

[0036] The air purifier body 1 includes an inner shell 11 and an outer shell 12. The inner shell 11 is located inside the outer shell 12 and forms an air outlet channel 10 between them. The cross-section of the air outlet channel 10 is annular with the inner shell 11 as the center. The outer shell 12 and the inner shell 11 can be fixedly connected. It is understood that the air purifier body 1 is used to filter air, and it is equipped with an air filtration mechanism 3 and a fan 4 for delivering filtered air to the air outlet channel 10.

[0037] The heating component 2 includes a bracket 21 and a heating wire 22. The bracket 21 is fixed to the top of the inner shell 11. The heating wire 22 is fixedly connected to the bracket 21 and includes a number of heating whiskers 220 that are evenly distributed radially around the bracket 21. The heating whiskers 220 are evenly distributed at the relative positions of the air outlet channel 10 to evenly heat the air output from the air outlet channel 10.

[0038] For example, the heating wire 22 is made of a nickel-chromium alloy wire with high resistivity, oxidation resistance, and corrosion resistance, and is fixedly connected to the bracket by welding or crimping. The heating whiskers 220 are long and thin strips formed by bending the heating wire 22, and are evenly distributed around the bracket to form a ring-shaped heating structure. The number and length of the heating whiskers 220 are reasonably configured according to the heating requirements and power limitations of the air purifier to ensure that heat can be transferred evenly and efficiently to the air outlet duct 10, while avoiding local overheating.

[0039] The air purifier with the above technical solution forms an air outlet channel 10 between the inner and outer shells 12. The cross-section of the air outlet channel 10 is annular with the inner shell 11 as the center. A heating wire 22 is mounted on the top of the inner shell 11 via a bracket 21. The heating wire 22 heats the air output from the air outlet channel 10. Because the heating wire is evenly distributed in relative positions within the air outlet channel 10, it can evenly heat the air output from all areas of the air outlet channel 10 and ensures uniform wind resistance distribution as the air passes through the air outlet channel 10. It can be seen that the air purifier with the above technical solution improves the uniformity of heating effect and optimizes wind resistance distribution, enabling the air purifier to maintain stable air output and air purification performance while providing warm air.

[0040] In one embodiment where the heating wire 22 is fixedly connected to the bracket 21, see [reference needed]. Figure 3 and Figure 4 As shown, the bracket 21 includes a fixed frame 211 and a heat-conducting ring 212. The fixed frame 211 is fixedly connected to the inner shell 11, and the heat-conducting ring 212 is fixed around the fixed frame 211, forming a heating channel 210 between it and the outer shell 12. The heating channel 210 is positioned opposite to and connected to the air outlet channel 10. The heating wire 22 is fixedly connected to the heat-conducting ring 212, and the heating elements 220 are evenly distributed around the heat-conducting ring 212. During operation, air from the air outlet channel 10 enters the heating channel 210 and is heated by the evenly distributed heating elements within the heating channel 210. The heating channel 210 facilitates air convergence, thereby improving heating efficiency.

[0041] For example, see Figure 3 and Figure 4 As shown, the heating wire 22 is wound around the outer periphery of the heat-conducting ring 212 and fixed relative to the heat-conducting ring 212.

[0042] For example, the heat-conducting ring 212 is made of a copper or aluminum alloy material with high thermal conductivity and corrosion resistance, possessing excellent thermal conductivity and mechanical strength. The shape of the heat-conducting ring 212 matches the mounting bracket 211, forming a heating channel 210 between it and the outer casing 12. The width and shape of the heating channel 210 are optimized according to the overall size and heating requirements of the air purifier to ensure that heat can be transferred evenly and efficiently to the air outlet channel 10.

[0043] For example, the mounting bracket 211 is connected to the inner housing 11 by screws or clips to fix it relative to the inner housing 11.

[0044] The aforementioned fixing bracket 211 and heat-conducting ring 212 are fixedly connected in the following way: the fixing bracket 211 is provided with a slot 213 or mounting hole for installing the heat-conducting ring 212, ensuring that the heat-conducting ring 212 can be stably and firmly fixed to the periphery of the fixing bracket 211. For example, see [reference needed]. Figure 4 As shown, the mounting bracket 211 has several slots 213, and the heat-conducting ring 212 is snapped into the inner side of the slots 213. During installation, the heat-conducting ring 212 is connected to the mounting bracket 211 by snapping, without the need for additional fasteners or adhesives. During the snapping process, the edge of the heat-conducting ring 212 is snapped into the slots 213 of the mounting bracket 211, forming a tight connection structure. This snapping method not only simplifies the installation process but also improves the stability and reliability of the connection.

[0045] To improve heating efficiency, see [reference needed]. Figure 3 As shown, the heat-conducting rings 212 and heating wires 22 are arranged in groups, with at least two groups. Each group of heat-conducting rings 212 and heating wires 22 is spaced apart along the extension direction of the heating channel 210. The grouping of heat-conducting rings 212 and heating wires 22 can be rationally configured according to the heating requirements and power limitations of the air purifier to ensure that heat is transferred evenly and efficiently to the air outlet channel 10. The spaced arrangement of each group of heat-conducting rings 212 and heating wires 22 along the extension direction of the heating channel 210 forms multiple heating zones. Each heating zone can operate independently and intelligently adjust according to the indoor temperature and air quality requirements. This not only improves heating efficiency but also enhances the adaptability and flexibility of the air purifier.

[0046] For example, to achieve precise control of each group of heat-conducting rings 212 and heating wires 22, the air purifier is equipped with an intelligent control system. The system can automatically adjust the power and operating time of each heating zone based on parameters such as indoor temperature, air quality, and the user-set target temperature to ensure a stable and comfortable indoor temperature. Simultaneously, the system also features fault alarms and overheat protection functions to ensure the safe operation of the air purifier.

[0047] To improve airflow efficiency, see Figure 3As shown, the inner shell 11 is cylindrical, and the inner shell 11, the air outlet duct 10, and the heating duct 210 are arranged along the same axis. The fact that the inner shell 11, the air outlet duct 10, and the heating duct 210 are all arranged along the same axis ensures that the air can maintain a stable flow direction and velocity during the flow process, which helps to reduce air resistance and energy consumption during the air flow process and improve the overall performance of the air purifier.

[0048] To increase the air output area, see [reference needed]. Figure 2 and Figure 3 As shown, the air purifier also includes a fixed cover 13, which is fixedly mounted on the top of the bracket 21 and is shaped like a frustum or cone. A flared channel 100 with a gradually increasing diameter is formed between the fixed cover 13 and the outer casing 12. The flared channel 100 is connected to the heating channel 210. The flared channel 100 not only guides airflow but also enhances the purification effect of the air purifier by increasing the airflow velocity. When air is heated by the heating channel 210, the space gradually increases as it enters the flared channel 100, thereby increasing the area of ​​the air purifier that outputs air.

[0049] Further, see Figure 2 and Figure 3 As shown, the air purifier also includes a guide shroud 14, which is connected to the outer casing 12 and serves to cover the top of the flared channel 100. The guide shroud 14 has several air outlets 140, which are evenly distributed in relative positions within the flared channel 100. By guiding airflow to the air outlets 140, the guide shroud 14 achieves uniform distribution and rapid discharge of purified air.

[0050] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
