[0002] An air purifier is a device that improves indoor air quality by removing various pollutants from the air using different technologies, creating a healthier and more comfortable living and working environment. Currently, some air purifiers use a spherical design at the air outlet, causing the air to converge towards the center of the spherical surface before being blown out. However, this design results in a smaller airflow area, leading to a more concentrated airflow and a poor user experience. Utility Model Content

[0013] The first blocking part is located above the inner air guide, and the second blocking part is located below the inner air guide. The air duct is divided into two sub-air ducts, left and right, by the first blocking part and the second blocking part.

[0017] Optionally, the airflow guide section is further provided with a plurality of airflow guide vanes to limit the direction of the airflow blown out from the air outlet.

[0018] Optionally, the cross-sectional dimension of the mounting portion is larger than the cross-sectional dimension of the flow guide portion.

[0019] Optionally, it also includes at least one heating component disposed at the mounting portion, such that air blown from the air duct passes through the heating component before being blown out from the air outlet.

[0020] Optionally, each of the heating components includes:

[0021] Multiple heating modules, each heating module including at least one heating element and a first heat dissipation element connected to both sides of the heating element, the heating element extending in a straight line, and the side of each first heat dissipation element connected to the heating element extending in a straight line; and

Detailed Implementation

[0047] In the description of this embodiment, it should be understood that the terms "length", "width", "height", "up", "down", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", "front", "back", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] As a specific embodiment of this utility model, as shown in Figures 1-5, this embodiment provides an air outlet structure 100, which is mainly used in an air handling device 200. The air outlet structure 100 may include an inner air guide 110, an outer air guide 120, a first housing 130, and an air outlet 140. The outer air guide 120 and the inner air guide 110 together define an air duct 150. The first housing 130 is generally an arc surface; its surface can be a combination of an arc surface and a plane, or entirely an arc surface. Preferably, in this embodiment, all surfaces of the first housing 130 are arc surfaces. The air outlet 140 may include an annular air outlet 141, which is positioned downstream of the air duct 150 so that gas within the air duct 150 is blown out through the air outlet 141. The air outlet 141 surrounds the outer periphery of the first housing 130. The air outlet 141 of the air outlet component 140 is further provided with a curved surface 142, the inner periphery of which is connected to the outer periphery of the first housing 130. The curvature of the curved surface 142 is opposite to the surface curvature of the first housing 130, and the curved surface 142 extends inward from the air outlet 141 along a direction that is obtuse to the air outlet direction, so as to prevent the air blown from the air outlet 141 from converging inward along the surface of the first housing 130.

[0049] Specifically, the air outlet structure 100 of this embodiment may include an inner air guide 110, an outer air guide 120, a first housing 130, and an air outlet 140. The inner air guide 110 and the outer air guide 120 define an air duct 150, the cross-section of which may be annular. The air within the air duct 150 is blown out through the air outlet 141 of the air outlet 140, which may also be annular. Preferably, the air outlet 141 is circular. The surface of the first housing 130 is generally arc-shaped. If the first housing 130 is directly disposed on the side of the air outlet 141, the air from the air outlet 141 will converge inward along the surface of the first housing 130 (due to the Coanda effect). In this embodiment, a curved surface 142 is provided between the first housing 130 and the air outlet 141. The curvature of the curved surface 142 is opposite to the curvature of the surface of the first housing 130, and the extension direction of the curved surface 142 forms an obtuse angle with the air outlet 141's air outlet direction. This curved surface 142 disrupts the phenomenon of air outlet 141 converging towards the inside of the first housing 130, thereby allowing the air outlet 141 in this embodiment to be unaffected by the first housing 130. This prevents the air from converging towards the inside of the surface of the first housing 130, increases the air outlet area, accelerates the mixing speed of gases at different locations, and improves the user experience.

[0050] As a specific embodiment of this utility model, as shown in Figures 4 and 5, the plane where the inlet position of the air duct 150 is located and the plane where the outlet position is located have a certain angle, so that the air intake direction a and the air outlet direction b of the gas in the air duct 150 have an angle.

[0051] Specifically, in this embodiment, the inlet and outlet of the air duct 150 have a certain angle (i.e., they are not parallel), so that the air intake direction a and the air outlet direction b have a certain angle (i.e., they are not parallel). This allows the air outlet structure 100 of this embodiment to be set at an angle. By rotating the air outlet structure 100, the area covered by the air outlet is larger, making air purification easier and more uniform, and further improving the user experience.

[0052] As a specific embodiment of this utility model, a blocking part is provided between the inner air guide 110 and the outer air guide 120. This blocking part can divide the air duct 150 into multiple sub-air ducts. Specifically, dividing the air duct 150 into multiple sub-air ducts in this embodiment can increase the gas flow rate, that is, increase the air outlet speed, and can also design the position of the sub-air ducts according to the actual situation, thereby adjusting the air outlet position.

[0053] Specifically, as shown in Figures 6 and 7, in this embodiment, the outer side wall of the inner air guide 110 has a first blocking portion 111 and a second blocking portion 112 arranged opposite to each other. The outer sides of both the first blocking portion 111 and the second blocking portion 112 are in contact with the inner side wall of the outer air guide 120, so that the air duct 150 is divided into two sub-air ducts. These two sub-air ducts can be distributed vertically or horizontally. In this embodiment, the sub-air ducts are distributed horizontally. Specifically, the first blocking portion 111 and the second blocking portion 112 in this embodiment can, on the one hand, divide the air duct 150, reduce the area of ​​the air outlet 141, and increase the flow rate of the gas at the air outlet 141; on the other hand, they can also allow the inner air guide 110 and the outer air guide 120 to contact and position each other, avoiding deformation or displacement.

[0054] More specifically, in this embodiment, when the plane where the inlet of the air duct 150 is located is horizontal, the plane where the outlet of the air duct 150 is located is inclined (as shown in Figures 1, 2, 4, and 5). The first blocking part 111 is located above the inner air guide 110, and the second blocking part 112 is located below the inner air guide 110. The air duct 150 is divided into two sub-air ducts, left and right, by the first blocking part 111 and the second blocking part 112.

[0055] Specifically, in this embodiment, the inlet of the air duct 150 is horizontal, so the air intake direction a is vertical. Since the air outlet direction b has a certain angle with the air intake direction a, the air outlet 141 in this embodiment is tilted.

[0056] More specifically, in this embodiment, the first blocking part 111 and the second blocking part 112 are respectively provided above and below the inner air guide 110. Therefore, the air duct 150 is formed into two sub-air ducts, and the air outlet 141 is also formed into two, left and right. This allows the air to blow out from both sides, forming a ring-shaped airflow.

[0057] As a specific embodiment of the present invention, as shown in Figures 6 and 7, the first blocking part 111 of this embodiment may include two first guiding surfaces 1111. Both first guiding surfaces 1111 are planar, and the bottoms of the two first guiding surfaces 1111 are connected and gradually extend upward at a certain angle.

[0058] Specifically, in this embodiment, the first blocking portion 111 intersects at the lower middle section of the first guide surface 1111 and extends all the way to the gas outlet. The two first guide surfaces 1111 are directly integrated with the inner air guide 110. Furthermore, the outer sides of the two first guide surfaces 1111 are formed as side surfaces, connecting the outer sides of the two first guide surfaces 1111. In this embodiment, the two first guide surfaces 1111 gradually separate upwards from the bottom at a certain angle, essentially guiding the gas flow along the gas flow direction, allowing the gas to flow along the air outlets on both sides.

[0059] As a specific embodiment of the present invention, as shown in Figures 6 and 7, the second blocking part 112 of this embodiment may include two second guiding surfaces 1121. Both second guiding surfaces 1121 are curved surfaces. The bottoms of the two second guiding surfaces 1121 are connected and gradually separate upward at a certain angle, and bend towards each other.

[0060] Specifically, the structure of the second blocking part 112 in this embodiment is basically the same as that of the first blocking part 111, except that the second guide surface 1121 of the second blocking part 112 is a curved surface 142. The second blocking part 112 also gradually separates from the bottom to both sides and extends upward. The airflow can also flow along the second blocking part 112 to the air outlets on both sides. Through the first blocking part 111 and the second blocking part 112, the gas in the air duct 150 can flow smoothly into the two air outlets 141 and then be blown out, without causing turbulence in the gas in the air duct 150 and resulting in airflow disturbance.

[0061] As a specific embodiment of this utility model, as shown in Figures 8-10, the air outlet structure 100 of this embodiment may further include at least one guide member 160. The guide member 160 may include an installation part 161 and a guide part 162. The installation part 161 is connected to the inner air guide member 110 and the outer air guide member 120 and communicates with the air duct 150. The guide part 162 is connected to the air outlet member 140. The gas in the air duct 150 passes through the installation part 161 and the guide part 162 in sequence and is blown out from the air outlet 141 of the air outlet member 140.

[0062] Specifically, the guide member 160 in this embodiment may include a mounting part 161 and a guide part 162. Since the air duct 150 in this embodiment is divided into two parts, the guide member 160 in this embodiment is also two parts.

[0063] In this embodiment, the cross-sectional area of ​​the mounting portion 161 is larger than the cross-sectional area of ​​the guide portion 162, thereby increasing the flow velocity of the air from the duct 150 as it passes through the mounting portion 161 to the guide portion 162.

[0064] The mounting section 161 can not only be connected and installed with the inner air guide 110 and the outer air guide 120, but other components, such as heating components, can also be installed inside it.

[0065] Specifically, in this embodiment, the airflow guide section 162 is also provided with a plurality of airflow guide vanes 1621 to limit the direction of the airflow blown out from the air outlet 141.

[0066] Specifically, in this embodiment, the air outlet 141 is designed at an angle, so its air outlet direction is tilted upwards. This embodiment uses guide vanes 1621 to define the air outlet direction, allowing it to be changed according to the design. Specifically, the guide vanes 1621 in this embodiment are all tilted downwards in a ring, so that the air blown from the air outlet 141 is basically horizontal. When the air outlet 141 can rotate, the sweeping range can be further expanded.

[0067] As a specific embodiment of the present invention, as shown in Figures 10-13, the air outlet structure 100 of this embodiment may further include at least one heating component 170. The heating component 170 is disposed at the mounting portion 161 so that the air blown out from the air duct 150 passes through the heating component 170 and is then blown out from the air outlet 141.

[0068] Specifically, the air outlet structure 100 of this embodiment may further include at least one heating component 170, so that the air blown out from the air outlet structure 100 can be hot air, thereby avoiding the indoor air being too cold due to the air blowing out when the air outlet structure 100 is used in winter, which would affect the user experience. In addition, since the air outlet structure 100 can blow hot air, devices using the air outlet structure 100 (such as air purifiers, fans, etc.) can be used as heating devices, thereby increasing the range of applications of the device.

[0069] As a specific embodiment of this utility model, each heating component 170 may include a plurality of heating modules 171 and a connector 172. Specifically, each heating module 171 may include at least one heating element 1711 and a first heat dissipation element 1712 connected to both sides of the heating element 1711. The heating element 1711 extends in a straight line, and the side of each first heat dissipation element 1712 connected to the heating element 1711 extends in a straight line. The connector 172 connects the plurality of heating modules 171 to each other to form a structure that matches the cross-section of the mounting part 161.

[0070] Specifically, the heating module 171 in this embodiment may include multiple heating modules 171 and connectors 172, and the heating module 171 may further include a heating element 1711 and a first heat sink 1712. Generally, the heating element 1711 is a ceramic plate made of PTC material. PTC is an abbreviation for Positive Temperature Coefficient. PTC heating devices are usually made of PTC material, which has special resistance-temperature characteristics, that is, within a certain temperature range, its resistance increases with the increase of temperature, and it can generate heat when energized. The first heat sink 1712 can be disposed next to the heating element 1711, in contact with the heating element 1711, to dissipate the heat generated by the heating element 1711. The first heat sink 1712 can be a corrugated sheet or other heat dissipation structure, and can be made of materials with good thermal conductivity such as aluminum or copper.

[0071] More specifically, since the air outlet 141 in this embodiment is annular, the air guide 160 is also basically designed as an arc-shaped structure. The heating component 170 is located at the mounting portion 161, therefore, the heating component 170 also needs to be designed as an arc-shaped structure matching the mounting portion 161. Since the heating element 1711 in this embodiment is a ceramic plate, it is generally flat. To form it as an arc-shaped structure, the prior art directly forms the first heat sink 1712 as an arc shape, and then contacts it with multiple interconnected heating elements 1711 that are formed as zigzag lines, ultimately forming an arc-shaped heating component. However, this design leads to poor contact at many of the contact surfaces between the first heat sink 1712 and the heating element 1711, resulting in poor heat dissipation and affecting heat dissipation efficiency. In this embodiment, the heating component 170 is formed by multiple heating modules 171 and connecting members 172. Each heating module 171 may include at least one heating element 1711 and a first heat sink 1712. Since the heating element 1711 extends in a straight line, and the portion of the first heat sink 1712 that contacts the heating element 1711 also extends in a straight line, the first heat sink 1712 and the heating element 1711 are in contact, thus not affecting the heat dissipation effect of the first heat sink 1712. Furthermore, since the cross-section of the mounting portion 161 is arc-shaped, in this embodiment, multiple heating modules 171 can be connected together using the connector 172 to form a shape matching the cross-section of the mounting portion 161. For example, although each heating module 171 extends in a straight line, connecting multiple straight-extending heating modules 171 to form a structure resembling or nearly an arc satisfies both the arc structure requirement and the heat dissipation effect.

[0072] As a specific embodiment of the present invention, each first heat sink 1712 is bent to form a bent cross section. Each first heat sink 1712 includes a plurality of first bent portions 1713 on the side close to the heat sink 1711. The plurality of first bent portions 1713 are arranged side by side along a straight line so that all the first bent portions 1713 are in contact with the heat sink 1711.

[0073] Specifically, in this embodiment, each first heat sink 1712 has a bent structure. The continuous bending forms a denser structure, increasing the contact area between the first heat sink 1712 and the air, thereby increasing the heat dissipation performance of the first heat sink 1712 and improving the heating efficiency of the heating assembly 170. In addition, the multiple first bends 1713 extend in a straight line, so that all of the first bends 1713 can contact the heat-generating element 1711, further ensuring the heat dissipation effect and improving the heating efficiency.

[0074] As another specific embodiment of this utility model, each first heat sink 1712 may further include a plurality of second bends 1714 on the side away from the heat sink 1711. Each heating module 171 may further include a second heat sink 1715, one side of each second heat sink 1715 being connected to each second bend 1714 of the corresponding heat sink 1711, and the other side of each second heat sink 1715 being connected to the connector 172.

[0075] Specifically, in this embodiment, the second heat sink 1715 contacts each of the second bends 1714, thereby ensuring that all the heat from the first heat sink 1712 can be transferred to the second heat sink 1715. The connector 172 can be connected to the second heat sink 1715, forming the second heat sink 1715 into a structure that matches the mounting portion 161. In this embodiment, the second heat sink 1715 can be a metal sheet, and the connector 172 can also be a metal sheet, both possessing a certain degree of ductility. Therefore, both the second heat sink 1715 and the connector 172 can be designed according to the direction and structure of the extension of the second bends 1714, ensuring that the second heat sink 1715 is in complete contact with the second bends 1714.

[0076] Preferably, the plurality of second bends 1714 can be arranged side by side along a straight line, so that the second heat sink 1715 is also formed with a straight cross section, while the connector 172 can be formed with a broken line shape, wherein the straight line segment contacts the second heat sink 1715.

[0077] Specifically, in this embodiment, a first heat dissipation component 1712 is provided on both sides of the heat-generating component 1711. Therefore, a second heat dissipation component 1715 is provided outside the first heat dissipation component 1712 on each side, and a connector 172 is provided outside each second heat dissipation component 1715. Therefore, the connector 172 may include a first connector 1721 and a second connector 1722, and the first connector 1721 and the second connector 1722 respectively connect multiple second heat dissipation components 1715 located on the same side of the heat-generating component 1711.

[0078] In some embodiments, as shown in Figures 11 and 12, the first connector 1721 and the second connector 1722 can also serve as conductive components for transmitting current. The heating element 1711 is electrically connected to the first connector 1721 and the second connector 1722 respectively through heat sinks. A first electrode terminal 1723 can be provided on the first connector 1721, and a second electrode terminal 1724 can be provided on the second connector 1722. The circuit can be connected through the first electrode terminal 1723 and the second electrode terminal 1724. When the circuit is turned on, current is introduced into the heating element 1711 through the first electrode terminal 1723, the second electrode terminal 1724, the first connector 1721, the second connector 1722, and the heat sinks on both sides of the heating element, so that the heating element 1711 generates heat.

[0079] Specifically, as shown in Figure 13, the heating assembly 170 may further include a temperature control element 173, which is used to control the temperature of the heating assembly 170. The temperature control element 173 can be directly mounted on the first connector 1721 and the second connector 1722. Since the first connector 1721 or the second connector 1722 has a flat surface at the connection point with the second heat sink 1715, the temperature control element 173 can maintain assembly stability when positioned at this location. Compared to the assembly structure that requires additional temperature control elements 173 on curved surfaces, this embodiment mounts the temperature control element 173 on a relatively flat surface without requiring additional assembly structure, reducing the number of accessories, decreasing the overall volume, and improving the assembly efficiency and temperature control accuracy of the temperature control element 173 to a certain extent.

[0080] Specifically, the heating assembly 170 of this embodiment may include a plurality of heating modules 171.
