[0002] In related technologies, blower devices can typically be equipped with a heating mechanism to heat the airflow blown out by the blower assembly in order to realize the hot air blowing function of the blower device.

[0003] Most current heating mechanisms are formed by welding the heating element and the heat-conducting structure to ensure stable heat transfer between them. However, during the welding process, solder leakage is prone to occur, resulting in insufficient welding between the heating element and the heat-conducting structure. This leads to poor connection stability between the heating element and the heat-conducting structure, reducing the structural reliability and stability of the heating mechanism. Utility Model Content

[0004] The main purpose of this invention is to propose a heating mechanism and a blowing device, which aims to achieve reliable welding of the heating element and the heat-conducting components, thereby improving the overall structural stability and reliability of the heating mechanism.

[0005] To achieve the above objectives, the heating mechanism proposed in this utility model includes a heat-conducting component and a heating element. The heat-conducting component has an annular receiving groove, and multiple heat dissipation fins are spaced around its outer periphery. The heating element is disposed in the receiving groove and includes a connecting component, a heating wire, an insulating heat-conducting layer, and a heat-conducting outer layer. The insulating heat-conducting layer wraps around the heating wire, and the heat-conducting outer layer wraps around the insulating heat-conducting layer. The connecting component is connected to both ends of the heating wire and extends into the insulating heat-conducting layer. The heat-conducting outer layer is welded and fixed to the heat-conducting component.

[0006] In one embodiment, the heat-conducting assembly includes a support tray and a heat-conducting body. The support tray includes a bottom ring and an inner ring, with the inner ring bent and connected to the inner side of the bottom ring. The heat-conducting body is connected to the bottom ring and is arranged around the support tray. The heat-conducting body, the bottom ring, and the inner ring together form the receiving groove. A plurality of heat dissipation fins are arranged around the outer periphery of the heat-conducting body.

[0007] In one embodiment, the bottom ring has a limiting protrusion located between the heat-conducting body and the heating element. And / or, the bottom ring has a positioning buckle, the heat-conducting body has a positioning notch, and the positioning buckle engages with the positioning notch.

[0008] In one embodiment, the heating mechanism has a thickness direction, and the height of the inner ring along the thickness direction is greater than the height of the heating element along the thickness direction. And / or, the bottom ring and the inner ring are integrally formed.

[0009] In one embodiment, the inner ring has a mounting edge that bends and extends away from the bottom ring, and the mounting edge has a mounting hole; the heating mechanism further includes a fastener that passes through the mounting hole.

[0010] In one embodiment, the heat-conducting component further includes a gasket disposed above the mounting perimeter and stacked with the mounting perimeter, and the fastener passing through the gasket.

[0011] In one embodiment, a connecting structure is provided on the outer side of the heat-conducting body, and the connecting structure is located between two adjacent heat dissipation fins; the heating mechanism further includes a temperature control device, which is connected to the connecting structure and located above the opening of the receiving groove.

The receiving groove provides better positioning for the heating element, preventing it from shifting during processing. Simultaneously, the receiving groove stably loads solder, ensuring that the molten solder fully fills the gap between the heat-conducting outer layer of the heating element and the inner wall of the receiving groove. This allows the heating element to be stably welded and fixed to the heat-conducting component, effectively preventing solder overflow and leakage during processing, reducing connection gaps between the heating element and the heat-conducting component caused by solder leakage, and further enhancing the connection stability between the heating element and the heat-conducting component, thus improving the overall structural stability and reliability of the heating mechanism.

[0029] In related technologies, blower devices typically incorporate a heating mechanism to heat the airflow emitted by the fan assembly, thereby achieving the blower's hot air function. Currently, most heating mechanisms are formed by welding a heating element to a heat-conducting structure, ensuring stable heat transfer between them. However, solder leakage is prone to occur during the welding process, leading to insufficient welding between the heating element and the heat-conducting structure, resulting in poor connection stability and reduced structural reliability and stability of the heating mechanism. To address these issues, this utility model proposes a heating mechanism 100.

[0030] Please see Figures 1 to 6In one embodiment of the present invention, the heating mechanism 100 includes a heat-conducting component 10 and a heating element 30. The heat-conducting component 10 has an annular receiving groove 10a formed therein, and a plurality of heat dissipation fins 131 are spaced around the outer periphery of the heat-conducting component 10. The heating element 30 is disposed in the receiving groove 10a and includes a connecting element 31, a heating wire 33, an insulating heat-conducting layer 35, and a heat-conducting outer layer 37. The insulating heat-conducting layer 35 wraps the heating wire 33, and the heat-conducting outer layer 37 wraps the insulating heat-conducting layer 35. The connecting element 31 is connected to both ends of the heating wire 33 and extends into the insulating heat-conducting layer 35. The heat-conducting outer layer 37 is welded and fixed to the heat-conducting component 10.

[0031] It is understandable that the heat-conducting component 10 can be made of a material with good thermal conductivity. By welding and fixing the heating element 30 to the heat-conducting component 10, the heat generated by the heating element 30 can be conducted to the heat-conducting component 10. The heat dissipation area of ​​the heating mechanism 100 is increased by the multiple heat dissipation fins 131 on the outer periphery of the heat-conducting component 10, allowing the heat to be dissipated more fully. At this time, by setting the heating mechanism 100 in the blower device 1000, the heating mechanism 100 can be installed in the air duct formed in the blower device 1000. As the airflow generated by the operation of the fan assembly 200 blows outward along the air duct, it can flow through the heat dissipation fins 131, allowing the airflow to carry the heat dissipated by the heat dissipation fins 131. This enables the blower device 1000 to blow out hot air with a certain temperature, achieving the hot air blowing effect of the blower device 1000.

[0032] The heat-conducting component 10 can be configured with a ring-shaped, square-shaped, or semi-circular ring-shaped structure with a certain arc notch, so that an annular receiving groove 10a can be formed by recessing the inner ring 113 of the heat-conducting component 10. At this time, the structure of the heating element 30 can be configured to correspond to the groove structure of the receiving groove 10a. The heating element 30 can be installed in the receiving groove 10a, and the inner wall of the receiving groove 10a abuts against the heating element 30, so as to realize the limited installation of the heating element 30 on the heat-conducting component 10, effectively preventing the heating element 30 from deviating from the inner cavity of the heat-conducting component 10 during processing, and ensuring the heat transfer efficiency between the heating element 30 and the heat-conducting component 10.

[0033] During the processing, the heating mechanism 100 can load solder into the receiving tank 10a, melt the solder and let it flow into the receiving tank 10a, so that the molten solder fills the gap between the heating element 30 and the inner wall of the receiving tank 10a; or the solder particles can be poured into the receiving tank 10a, and the solder can be melted by heating the heat-conducting component 10 and flow into the gap between the heating element 30 and the inner wall of the receiving tank 10a. After the solder cools and solidifies, the solder can be used to connect the heat-conducting outer layer 37 of the heating element 30 and the inner wall of the heat-conducting component 10, so that the heating element 30 and the heat-conducting component 10 are welded into a whole, so as to achieve stable production processing of the heating mechanism 100. The accommodating groove 10a can form a container with a certain capacity, which is conducive to the stable loading of solder for welding and prevents solder overflow and leakage. Compared with the existing technology of using partitions or other tools to surround the heating element 30 for welding, this application can better simplify the processing steps of the heating mechanism 100, realize more convenient welding processing of the heating mechanism 100, and at the same time enable the heat-conducting component 10 to better increase the contact area with the heating element 30 by using the accommodating groove 10a, so that the heat generated by the heating element 30 can be better transferred to the heat-conducting component 10, improve the thermal energy utilization rate of the heating mechanism 100, and further improve the practicality and structural reliability of the heating mechanism 100.

[0034] It should be noted that in the heating element 30, the connecting part 31 can be made of a conductive material for welding or plugging with the power cord. For example, it can be made of steel and nickel-plated to ensure that the connecting part 31 has a certain strength and corrosion resistance. The heating wire 33 can be made of a metal material with good electrical conductivity and heating performance, such as iron-chromium-aluminum alloy or nickel-chromium alloy. The heat-conducting outer layer 37 can be made of a tubular structure of a metal or other material with good thermal conductivity, such as a copper tube or aluminum tube. The heating wire 33 is housed in the tubular structure, and the inside of the tube is filled with an insulating material with good thermal conductivity to prevent leakage, such as magnesium oxide or aluminum oxide. The heating element 30 reduces the risk of leakage by wrapping the heating wire 33 with an insulating and thermally conductive layer 35. A thermally conductive outer layer 37 is provided outside the insulating and thermally conductive layer 35 to house the insulating and thermally conductive material of the insulating and thermally conductive layer 35 and protect the heating wire 33 from accidental damage. The thermally conductive outer layer 37 wraps around the periphery of the insulating and thermally conductive layer 35 and may have flanges at its ends to wrap around the two end faces of the insulating and thermally conductive layer, but it does not contact the electrical connector 31. Furthermore, the insulating and thermally conductive layer 35 isolates the heating wire 33 from the air, preventing oxidation and further improving its service life. The heating element 30 can generate heat energy by connecting the heating wire 33 to electricity, and this heat energy is transferred to the thermally conductive assembly 10 through the insulating and thermally conductive layer 35 and the thermally conductive outer layer 37. Multiple heat dissipation fins 131 on the outer periphery of the thermally conductive assembly 10 increase the heat dissipation area, ensuring better hot air blowing effect of the blower 1000. At this time, by welding and fixing the heat-conducting outer layer 37 and the heat-conducting component 10 to form the inner wall of the receiving groove 10a, the heat-conducting body 30 can be effectively prevented from leaking electricity to the heat-conducting component 10 under the action of the insulating heat-conducting layer 35, so that there is only a heat transfer relationship between the heat-conducting body 30 and the heat-conducting component 10, and the stable operation of the heating mechanism 100 is guaranteed.

[0035] The technical solution of this utility model forms a receiving groove 10a inside the heat-conducting component 10, so that the heating element 30 is installed in the receiving groove 10a. During the production and processing, solder is loaded into the receiving groove 10a, and under the connection effect of the solder, the heat-conducting outer layer 37 of the heating element 30 is stably welded to the heat-conducting component 10 to form a whole, ensuring the stable and reliable processing of the heating mechanism. Under the action of the receiving groove 10a, the heating element 30 can be better limited, preventing the heating element 30 from shifting during processing. At the same time, the receiving groove 10a can be used to stably load solder, so that the solder can fully fill the gap between the heat-conducting outer layer 37 of the heating element 30 and the inner wall of the receiving groove 10a in the molten state. This allows the heating element 30 to be stably welded and fixed on the heat-conducting component 10, effectively preventing solder overflow and leakage during processing, reducing the connection gap between the heating element 30 and the heat-conducting component 10 caused by solder leakage, better enhancing the connection stability between the heating element 30 and the heat-conducting component 10, and improving the overall structural stability and reliability of the heating mechanism 100.

[0036] See Figure 5 In one embodiment of the present invention, the heating element 30 further includes an isolation member 39, which wraps around the outer wall of the electrical contact member 31 and extends into the insulating and heat-conducting layer 35.

[0037] In this embodiment, the gaps at both ends of the heat-conducting outer layer 37 can be sealed by the insulating member 39, reducing the risk of oxidation of the heating wire 33 or short circuits and leakage. Therefore, the heat-conducting outer layer 37 can be sealed to the periphery of the insulating member 39, or the end edge of the heat-conducting outer layer 37 can be used to wrap the end face of the insulating member 39 without contacting the electrical connection member 31, thus ensuring stable heating of the heating element 30.

[0038] The insulating element 39 can be made of ceramic material, formed into a columnar or bead-like shape, and sealed at both ends of the heat-conducting outer tube. Ceramic is a good electrical insulating material, which can prevent current from leaking from the heating wire 33 of the heating element 30 to the external metal shell or other conductive parts, thereby avoiding short circuits and electric shock hazards. Furthermore, ceramic is stable at high temperatures and is not easily melted or deformed, thus helping to improve the overall safety performance of the heating element 30.

[0039] See Figures 2 to 4 In one embodiment of the present invention, the heat-conducting component 10 includes a support tray 11 and a heat-conducting body 13. The support tray 11 includes a bottom ring 111 and an inner ring 113. The inner ring 113 is bent and connected to the inner side of the bottom ring 111. The heat-conducting body 13 is connected to the bottom ring 111 and is arranged around the support tray 11. The heat-conducting body 13, the bottom ring 111 and the inner ring 113 surround to form a receiving groove 10a. A plurality of heat dissipation fins 131 are arranged around the outer periphery of the heat-conducting body 13.

[0040] In this embodiment, the heat-conducting component 10 can be formed by assembling a separate support tray 11 and a heat-conducting body 13. The support tray 11 is formed by bending the bottom edge of the inner ring 113 to connect to the inner side of the bottom ring 111, so that the heat-conducting body 13 can be connected to the bottom ring 111. The heat-conducting body 13 and the inner ring 113 are arranged at intervals relative to each other. In this way, the inner wall of the heat-conducting body 13, the bottom ring 111 and the inner ring 113 can be used to form a groove structure with a cross-section similar to a U-shape, C-shape or V-shape. The surface of the bottom ring 111 forms the bottom wall of the receiving groove 10a, and the inner wall of the heat-conducting body 13 and the inner ring 113 respectively form two opposite inner sidewalls of the receiving groove 10a. This allows the receiving groove 10a with a certain space to be formed inside the heat-conducting component 10 to load the heating element 30 and solder for welding, further improving the overall structural stability and reliability of the heating mechanism 100.

[0041] It should be noted that the heat-conducting body 13 can be fixed by welding the bottom surface to the surface of the bottom ring 111 so that the supporting tray 11 and the heat-conducting body 13 are connected to form a whole; or, the bottom ring 111 and the heat-conducting body 13 can be connected to form a whole by fasteners such as screws and pins; of course, the heat-conducting body 13 and the bottom ring 111 can also be bonded by high-temperature resistant adhesive, etc. This application does not limit the connection and installation method of the heat-conducting body 13 and the bottom ring 111.

[0042] See Figure 4 In one embodiment of the present invention, the bottom ring 111 is provided with a limiting protrusion 1111, which is located between the heat-conducting body 13 and the heating element 30.

[0043] In this embodiment, the surface of the bottom ring 111 may be provided with a limiting protrusion 1111 facing the heating element 30. The limiting protrusion 1111 can be positioned between the heat-conducting body 13 and the heating element 30, and can be positioned in the gap between the heating element 30 and the inner wall of the heat-conducting body 13. This can play a certain role in limiting the heating element 30, better preventing the heating element 30 from shifting during the processing, achieving a more stable welding and fixing effect between the heating element 30 and the heat-conducting body 13, and further improving the overall structural reliability and stability of the heating mechanism 100.

[0044] Furthermore, by utilizing the limiting protrusion 1111 in the gap between the heating element 30 and the inner wall of the heat-conducting body 13, the amount of solder can be reduced to a certain extent, thereby lowering the production and processing costs of the heating mechanism 100. The limiting protrusion 1111 can be formed by stamping on the bottom ring 111, or it can be welded to the bottom ring 111, or it can be integrally cast with the bottom ring 111. This application does not limit the form in which the limiting protrusion 1111 is provided on the bottom ring 111.

[0045] See Figure 2 In one embodiment of the present invention, the bottom ring 111 is provided with a positioning buckle 1113, and the heat-conducting body 13 is provided with a positioning notch 133, and the positioning buckle 1113 is engaged with the positioning notch 133.

[0046] In this embodiment, the bottom ring 111 can be bent and extended outward to form a positioning buckle 1113, so that the positioning buckle 1113 and the inner ring 113 are spaced apart. At this time, a positioning notch 133 matching the positioning buckle 1113 can be provided on the heat-conducting body 13. The positioning notch 133 can be a gap between two adjacent heat-conducting fins, or a groove or through hole can be recessed on the bottom surface of the heat-conducting body 13 to form the positioning notch 133. Furthermore, when the heat-conducting body 13 and the bottom ring 111 are assembled, the positioning buckle 1113 on the bottom ring 111 can be inserted into the positioning notch 133 of the heat-conducting body 13. By using the engagement of the positioning buckle 1113 and the positioning notch 133, the positioning assembly of the heat-conducting body 13 on the bottom ring 111 is achieved. This helps to better avoid misalignment of the heat-conducting body 13 and further improves the overall structural stability and reliability of the heating mechanism 100.

[0047] See Figure 4 In one embodiment of the present invention, the heating mechanism 100 has a thickness direction, and the height of the inner ring 113 along the thickness direction is greater than the height of the heating element 30 along the thickness direction.

[0048] In this embodiment, by setting the height of the inner ring 113 to be greater than the height of the heating element 30, that is, by setting the depth of the receiving groove 10a to be greater than the height of the heating element 30, the heating element 30 can be more stably housed in the receiving groove 10a, and the molten solder can more fully wrap the heating element 30, so that the heating element 30 can be fully welded and fixed to the heat-conducting component 10, ensuring the heat transfer efficiency between the heating element 30 and the heat-conducting component 10, and at the same time better preventing the heating element 30 from loosening, further improving the overall structural stability and reliability of the heating mechanism 100.

[0049] In one embodiment of this utility model, the bottom ring 111 and the inner ring 113 are integrally formed.

[0050] In this embodiment, the bottom ring 111 and the inner ring 113 can be manufactured using an integral molding structure. The integral molding of the bottom ring 111 and the inner ring 113 can be achieved using 3D printing technology or integral casting technology, which helps to better enhance the overall structural strength of the support tray 11, so that the heat conduction component 10 can more stably support the support heating element 30, ensure reliable welding of the heating element 30 to the support tray 11 and the heat conduction body 13, better avoid solder leakage, and further improve the overall structural stability and reliability of the heating mechanism 100.

[0051] See Figure 2 and Figure 4 In one embodiment of the present invention, the inner ring 113 is provided with a mounting edge 1131 that bends and extends in a direction away from the bottom ring 111, and the mounting edge 1131 is provided with a mounting hole 1133; the heating mechanism 100 also includes a fastener, which passes through the mounting hole 1133.

[0052] In this embodiment, the inner ring 113 is bent in a direction away from the bottom ring 111 to form a mounting edge 1131. The heating mechanism 100 can use the mounting edge 1131 as an assembly component. By providing mounting holes 1133 on the mounting edge 1131, when the heating mechanism 100 is installed in the blower 1000, the mounting edge 1131 can engage with the mounting structures such as bolt columns and support platforms inside the blower 1000. Then, fasteners such as bolts, screws, and pins are used to pass through the mounting holes 1133 and connect to the mounting structures inside the blower 1000. This achieves a stable assembly of the heating mechanism 100 inside the blower 1000, prevents the heating mechanism 100 from detaching, and further improves the structural stability and reliability of the heating mechanism 100.

[0053] By setting an mounting edge 1131 on the inner ring 113 of the carrying tray 11 to form the mounting structure of the heating mechanism 100, it is possible to avoid machining holes in the heat-conducting body 13 to form the mounting structure. This allows multiple heat dissipation fins 131 to be stably arranged around the outer periphery of the heat-conducting body 13, ensuring the heat transfer efficiency of the heating mechanism 100 and further improving the practicality and structural reliability of the heating mechanism 100.

[0054] See Figure 1 , Figure 2 and Figure 4 In one embodiment of the present invention, the heat-conducting component 10 further includes a gasket 15, which is disposed above the mounting edge 1131 and stacked with the mounting edge 1131, and fasteners are inserted through the gasket 15.

[0055] In this embodiment, by stacking a gasket 15 above the mounting edge 1131, fasteners can pass through the gasket 15 and the mounting holes 1133 of the mounting edge 1131 to connect to the blower 1000, so that the ends of the fasteners abut against the gasket 15 and press against the heat-conducting component 10, thus achieving a stable installation of the heating mechanism 100. At this time, the gasket 15 can be made of a material with certain high-temperature resistance and compressive strength, allowing the gasket 15 to better withstand the high temperature of the heating mechanism 100 and the pressure of the fasteners, preventing the mounting edge 1131 from breaking under excessive pressure, and further improving the overall structural stability and reliability of the heating mechanism 100.

[0056] In addition, the gasket 15 can also be made of a material with certain heat insulation properties. In this case, the gasket 15 can be used to insulate the fasteners from heat and prevent the fasteners from being affected by high temperature, so that the heating mechanism 100 can be installed more stably inside the blower 1000, further improving the practicality and reliability of the heating mechanism 100.

[0057] See Figure 1 In one embodiment of the present invention, a connecting structure 135 is provided on the outer side of the heat-conducting body 13, and the connecting structure 135 is disposed between two adjacent heat dissipation fins 131; the heating mechanism 100 also includes a temperature control device 50, which is connected to the connecting structure 135 and disposed above the opening of the receiving groove 10a.

[0058] In this embodiment, the connecting structure 135 can be a bolt post between two adjacent heat dissipation fins 131. Screws or other fastening structures can be used to pass through the temperature controller 50 and insert it onto the bolt post, achieving stable assembly of the temperature controller 50 and ensuring its stable operation. Alternatively, the connecting structure 135 can also be a platform between two adjacent heat dissipation fins 131. Screws or other fastening structures can be used to pass through the temperature controller 50 and insert it onto this platform, or a protrusion can be provided on the platform for inserting the temperature controller 50 for installation. Therefore, compared to the installation method of pasting the temperature controller 50 onto the heating element 30, this method can better improve the assembly stability and controllability of the temperature controller 50, prevent the temperature controller 50 from falling off, and ensure a more stable and reliable operation of the heating mechanism 100.

[0059] The temperature control device 50 can be a temperature control switch, which connects the electrical connector 31 of the heating element 30 to the temperature control switch, and then connects the temperature control switch to an external power source. This allows the temperature control switch to disconnect the circuit in time when the circuit connecting the heating mechanism 100 fails, preventing damage to the heating mechanism 100. Alternatively, the temperature control switch can be a temperature sensing component, which monitors the temperature of the heat generated by the heating element 30 to achieve precise temperature control of the heating mechanism 100. This allows the blower 1000 to better deliver hot air that meets the user's temperature requirements, further improving the practicality and structural reliability of the heating mechanism 100.

[0060] See Figure 1 In one embodiment of the present invention, a plurality of ribs 1311 are provided on the heat dissipation fin 131 at intervals, and the ribs 1311 extend to the adjacent heat dissipation fin 131.

[0061] Understandably, the heating mechanism 100 is used in the blower device 1000. Because the heat dissipation fins 131 on the heat-conducting component 10 are relatively thin and easily deformed by external forces in order to reduce wind resistance and increase the density of the heat dissipation fins 131 on the heat-conducting component 10, multiple ribs 1311 can be spaced apart on the heat dissipation fins 131. These ribs 1311 extend towards the adjacent heat dissipation fins 131, supporting the adjacent fins and effectively improving their resistance to deformation while ensuring sufficient ventilation area between them. Simultaneously, the spaced ribs 1311 on the heat dissipation fins 131 also increase the contact area between the heat-conducting component 10 and the airflow, allowing heat to be more fully transferred to the airflow and achieving a better hot air blowing effect in the blower device 1000.

[0062] This utility model also proposes a blower device 1000, which includes a fan assembly 200 and a heating mechanism 100. The specific structure of the heating mechanism 100 is as described in the above embodiments. Since this blower device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0063] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
