[0037] This application proposes a heating component 2.

[0038] Please refer to Figure 1. In one embodiment of this application, the heating component 2 includes a heating element 21 and a heat-conducting fin structure 22. The heat-conducting fin structure 22 extends circumferentially along the heating element 21 and is heat-conductingly connected to the heating element 21.

[0039] In this embodiment, the heating element 21 employs a specially designed heating structure, the specific structure of which is described in the next embodiment. It is understood that the heating element 21 can use conventional resistance wires or heating tubes. The heat-conducting fin structure 22 has multiple spaced-apart fin bodies 222. These spaced-apart fin bodies 222 can be directly mounted on the heating element 21, or they can be connected to one side of a connecting structure and then connected to the heating element 21 via the connecting structure. It should be noted that the connecting structure can be strip-shaped, circular, annular, or linear, and the multiple spaced-apart fins can be parallel to each other or radially arranged on the connecting structure. When the heating element 21 is annular, the multiple spaced-apart fins are arranged along the heating element 21 in a ring shape. When the heating element 21 is linear, the multiple spaced-apart fins are arranged along the heating element 21 in a linear shape. The same applies to other shapes. This allows the heating element 21 to better fit with the heat-conducting fin structure 22, facilitating heat transfer and installation. The connecting structure can be connected to the heating element 21 via a fixed connection or a detachable connection.

[0040] The heating component 2 proposed in this embodiment can be disposed within the air outlet channel 1a of the head assembly 100 and on the air outlet path of the air outlet channel 1a. In this embodiment, the heating component 2 uses a heating element 21 connected to a heat-conducting fin structure 22 for heat conduction. The heat-conducting fins increase the heat transfer speed on the heating element 21 and increase the heat exchange area between the air inlet and the heating component 2, thus achieving the beneficial effect of improving the heat exchange efficiency between the heating element 21 and the air inlet.

[0041] Further, please refer to Figures 2 and 3. In one embodiment of this application, the heating element 21 includes a contact element 211, a heating wire 212, an insulating and heat-conducting layer 213, and a heat-conducting outer layer 214. The insulating and heat-conducting layer 213 wraps around the heating wire 212, and the heat-conducting outer layer 214 wraps around the insulating and heat-conducting layer 213. The contact element 211 is connected to both ends of the heating wire 212 and extends into the insulating and heat-conducting layer 213.

[0042] In this embodiment, the connector 211 is made of a conductive material for welding or plugging with a power cord. For example, it can be made of steel and nickel-plated to ensure that the connector 211 has a certain strength and corrosion resistance. The heating wire 212 can be made of a metal material with good electrical conductivity and heating performance, such as an iron-chromium-aluminum alloy or a nickel-chromium alloy. The heat-conducting outer layer 214 can be made of a tubular structure of a metal or other material with good thermal conductivity, such as a copper tube or an aluminum tube. The heating wire 212 is housed in the tubular structure, and the tube is filled with an insulating material with good thermal conductivity to prevent leakage, such as magnesium oxide or aluminum oxide.

[0043] In this embodiment, the heating element 21 reduces the risk of leakage of the heating wire 212 by wrapping the heating wire 212 with an insulating and thermally conductive layer 213. A thermally conductive outer layer 214 is provided outside the insulating and thermally conductive layer 213 to accommodate the insulating and thermally conductive material of the insulating and thermally conductive layer 213 and protect the heating wire 212 from accidental damage. The thermally conductive outer layer 214 wraps around the periphery of the insulating and thermally conductive layer 213, and may have flanges at its ends to wrap around the two end faces of the insulating and thermally conductive layer 213, but without contacting the electrical connector 211. Furthermore, the insulating and thermally conductive layer 213 isolates the heating wire 212 from the air, preventing oxidation of the heating wire 212 and further improving its service life.

[0044] Furthermore, referring to Figure 2, in one embodiment of this application, the heating element 21 further includes an insulating element 215. The insulating element 215 wraps around the outer wall of the connecting element 211 and extends into the insulating heat-conducting layer 213. The insulating element 215 can seal the gaps at both ends of the heat-conducting outer layer 214, preventing the heating wire 212 from oxidizing or experiencing short circuits, leakage, or other risks. Therefore, the heat-conducting outer layer 214 can be sealed to the periphery of the insulating element 215, or the end flange of the heat-conducting outer layer 214 can be used to wrap around the end face of the insulating element 215 without contacting the connecting element 211. In this embodiment, the insulating element 215 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 212 of the heating tube 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 tube.

[0045] Furthermore, referring to Figure 1, in one embodiment of this application, the heating component 2 further includes a temperature control switch 24, which is electrically connected to the heating wire.

[0046] In this embodiment, at least one of the terminals at both ends of the heating element 21 is electrically connected to the temperature control switch 24 before being connected to the power supply. After the power supply is connected to the terminals 211 at both ends of the heating element 21, the heating wire 212 inside the heating element 21 heats up. The heat is conducted to the connected heat-conducting fin structure 22 through the internal insulating heat-conducting material and the high-heat material of the outer wall metal, thus dissipating the heat. The heat-conducting fin structure 22 has a fixed position for the temperature control switch 24. When the heat exceeds the temperature value monitored by the temperature control switch 24, the temperature control switch 24 disconnects the power supply, that is, the power supply line of the heating wire 212 is broken, and the temperature of the heat-conducting fin structure 22 gradually decreases. When the temperature of the heat-conducting fin structure 22 drops to a safe temperature, the temperature control switch 24 will naturally restore power, and the heating wire 212 will continue to heat up. This repeated process prevents overheating of the heating component 2, which could lead to fires or other hazards. The temperature control switch 24 can be a bimetallic strip temperature control switch or a thermistor temperature control switch. A bimetallic strip temperature control switch utilizes two metal strips with different coefficients of thermal expansion joined together. When the temperature changes, the bimetallic strip bends to varying degrees, triggering a circuit disconnection. When the temperature decreases, the bimetallic strip reconnects, restoring the circuit to a closed state. A thermistor temperature control switch utilizes the characteristic that the resistance of a thermistor changes with temperature. When the temperature rises, the resistance gradually increases, causing the current in the circuit to decrease. When the set temperature is reached, the resistance increases to block the current in the circuit, triggering a circuit disconnection. When the temperature decreases, the resistance also decreases, restoring the circuit to a closed state. Thermistor temperature control switches have advantages such as adjustable protection range, wide applicability, convenient operation, and high pressure resistance. Temperature control switches can have various structural forms; this application does not limit the structural form of the temperature control switch. Furthermore, the heating component can be equipped with various types of temperature control switches, and multiple temperature control switches can be connected in series to improve the safety performance of the heating component.

[0047] Further, referring to Figures 4 to 6, in one embodiment of this application, the heat-conducting fin structure 22 is detachably connected to the heating element 21; and / or, the heat-conducting fin structure 22 is an integrally formed structure; and / or, the heat-conducting fin structure 22 includes multiple fin bodies 222; multiple ribs 2221 are spaced apart on the fin bodies 222, and the ribs 2221 extend to an adjacent fin body 222; and / or, the heating assembly 2 further includes a first temperature sensing element, which is thermally connected to the heating element 21 or the heat-conducting fin structure 22 to monitor the temperature of the heating assembly 2; and / or, the heating assembly 2 further includes a second temperature sensing element, which is used to monitor the outlet air temperature of the head assembly 100.

[0048] In this embodiment, the detachable connection between the heat-conducting fin structure 22 and the heating element 21 can be achieved by snap-fitting, setting sliding grooves and slide rails, or setting bolts and screw holes. It should be noted that when implementing the detachable connection, sufficient contact area should be maintained between the heat-conducting fin structure 22 and the heating element 21 to ensure heat exchange efficiency. The detachable connection allows the heat-conducting fin structure 22 to be removed for cleaning, preventing excessive dust accumulation that could reduce heat dissipation. Damaged heating elements 21 can also be replaced without replacing the entire unit, thus reducing maintenance difficulty.

[0049] The heat-conducting fin structure 22 in this embodiment is an integrally molded structure. Referring to Figure 4, taking an annular heat-conducting fin structure 22 as an example, the heat-conducting fin structure 22 has a strip-shaped heat-conducting plate. Multiple spaced-apart fin bodies 222 are provided on one side of the heat-conducting plate. The fin body structure 222 and the heat-conducting plate are integrally molded. This strengthens the connection between the fin body 222 and the heat-conducting plate. Furthermore, the integral molding design eliminates gaps between the fin body 222 and the heat-conducting plate, reducing heat loss during heat conduction and improving heat conduction efficiency. It should be noted that the above is merely an illustrative example of an integrally molded design using an annular heat-conducting fin structure 22 and should not be considered a limitation of the technical solution of this application.

[0050] In order to reduce wind resistance and increase the density of the fin body 222, the fin body 222 is relatively thin and easily deformed by external forces. In order to strengthen the support between adjacent fin bodies 222, the heat-conducting fin structure 22 includes multiple fin bodies 222. Multiple ribs 2221 are spaced apart on the fin body 222. The ribs 2221 extend to the adjacent fin body 222. The ribs 2221 support the adjacent fin bodies 222, improve the deformation resistance of the fin body 222, and ensure sufficient ventilation area.

[0051] The heating component 2 also includes a first temperature sensing element, which is thermally connected to the heating element 21 or the heat-conducting fin structure 22 to monitor the temperature of the heating component 2. The first temperature sensing element can communicate with the display module to display the temperature of the heating component 2 in real time and issue control commands to adjust the heating temperature of the heating component 2, thereby improving the user experience.

[0052] The heating component 2 also includes a second temperature sensing element, which is used to monitor the outlet air temperature of the head assembly 100. In this embodiment, the second temperature sensing element is set in the air outlet direction of the head assembly 100, and can be located near the air outlet in the air duct of the head assembly 100. The second temperature sensing element can monitor the air temperature in real time, and then feed the air temperature back to the control unit. The control unit can control the power of the heating element 21 through electronic components (such as silicon controlled rectifiers), thereby regulating the temperature of the air outlet. This can achieve different temperatures for the air blown out of the air outlet at the same air outlet speed, or achieve the same temperature for the air blown out at different air outlet speeds. It should be noted that in some embodiments, the purpose of setting the second temperature sensing element may be different from that of the first temperature sensing element. The first temperature sensing element is for safety protection, while the second temperature sensing element monitors the air temperature and controls the air outlet temperature in real time.

[0053] Further, please refer to Figures 1, 4, 5 and 6. In one embodiment of this application, the heating element 21 is arranged in a ring shape, and the heat-conducting fin structure 22 is sleeved on the outer periphery of the heating element 21; or, the heat-conducting fin structure 22 includes a base plate 221 and a plurality of fin bodies 222 spaced apart along the periphery of the base plate 221, and the heating element 21 is connected to the base plate 221; or, the heating element 21 is arranged in a straight line, the heat-conducting fin structure 22 is connected to the side wall of the heating element 21 and extends along the length direction of the heating element 21.

[0054] In this embodiment, the heating element 21 is arranged in a ring shape, and the heat-conducting fin structure 22 includes multiple fin bodies 222 and an annular connecting plate. The heating element 21 is connected to the inner peripheral wall of the annular connecting plate, and the multiple fin bodies 222 are radially spaced on the outer peripheral wall of the annular connecting plate. The heating assembly 2 of this embodiment can adapt to most shapes of air outlet channels 1a, and airflow can pass through the middle of the ring, resulting in a large airflow volume.

[0055] In another embodiment, the heat-conducting fin structure 22 includes a base plate 221 and a plurality of fin bodies 222 spaced apart along the periphery of the base plate 221. The heating element 21 is connected to the base plate 221. The base plate 221 has a strong load-bearing capacity and can connect more and larger fin bodies 222, thereby increasing the heat exchange area and improving the heat exchange efficiency between the heating component 2 and the air intake.

[0056] In another embodiment, the heating element 21 is arranged in a straight line, and the heat-conducting fin structure 22 is connected to the side wall of the heating element 21 and extends along the length of the heating element 21. In this way, the air outlet 11a can be designed in a strip shape, which can heat the air blowing over a larger area. It can be applied to vertical or horizontal heating devices, improving the practicality of the heating component 2.

[0057] Further, referring to Figures 7, 11, and 12, in one embodiment of this application, the heating element 21 is detachably connected to the head assembly 100; or, the heat-conducting fin structure 22 is detachably connected to the head assembly 100; or, the heating assembly 2 further includes a heat-conducting fixing member 23, which is detachably connected to the head assembly 100, and the heat-conducting fin structure 22 and the heating element 21 are respectively connected to opposite sides of the heat-conducting fixing member 23.

[0058] In this embodiment, the heating element 21 or the heat-conducting fin structure 22 is provided with a connecting protrusion. The connecting protrusion has through holes, which can be used to connect to the head assembly 100 via bolts. It should be noted that the number of connecting protrusions and through holes can be increased as needed. Furthermore, the detachable connection between the heating element 21 or the heat-conducting fin structure 22 and the head assembly 100 is not limited to the use of connecting protrusions and through holes; it can also be achieved by using slide rails and grooves, snap-fit ​​structures, etc. The detachable connection allows the heat-conducting fin structure 22 to be removed for cleaning, preventing excessive dust accumulation that could reduce heat dissipation. It also allows damaged heating elements 21 to be replaced without replacing the entire machine, thus reducing maintenance difficulty. The heating element 21 and the heat-conducting fin structure 22 can also be connected by a heat-conducting fastener 23, which can be a welding material or heat-resistant adhesive, etc.

[0059] This application also proposes a head assembly 100, which can be applied to, but is not limited to, blower, heater and other blower devices.

[0060] Please refer to Figures 7, 8 and 13. In one embodiment of this application, the head assembly 100 includes a blower module 1 and a heating component 2 as described in any of the above embodiments. An air outlet channel 1a is formed in the blower module 1, and the heating component 2 is disposed in the air outlet channel 1a and on the air outlet path of the blower module 1.

[0061] In this embodiment, the head assembly 100 includes a blower module 1 and a heating assembly 2. The blower module 1 consists of a housing 11, a mounting structure 12, and a fan assembly 13. An air outlet channel 1a is formed inside the housing 11, and an air outlet 11a is provided. The housing 11 can be cylindrical, and the openings at both ends of the cylinder can serve as air inlets 113a and air outlets 11a. A straight air outlet channel 1a can be correspondingly provided inside the cylindrical housing 11 to avoid corners in the blowing path, improve the smoothness of air flow, and reduce the pressure on the fan assembly 13. Alternatively, a strip-shaped air inlet 113a and air outlet 11a can be re-established on the side of the cylinder for use in horizontal or vertical heating devices. The strip-shaped air outlet expands the range of airflow that users can feel, improving the practicality of the head assembly 100.

[0062] The fan assembly 13 is fixed inside the housing 11 by the mounting structure 12, while the heating assembly 2 is located inside the air outlet duct 1a, precisely in the air outlet path. The heat-conducting fin structure 22 of the heating assembly 2 is configured to correspond to the air outlet 11a, allowing hot air to leave the air outlet duct 1a immediately, reducing heat loss. Furthermore, since the heat-conducting fin structure 22 only needs to be configured to correspond to the air outlet 11a, its volume can be reduced, wind resistance can be lowered, airflow within the air outlet duct 1a can be smoother, and the material cost of the heat-conducting fin structure 22 can be reduced, which helps to reduce redundant design and lower structural costs.

[0063] It should be noted that the blower module 1 can also adopt a blower structure without blades 132, that is, the blades 132 are hidden. The blades 132 and the fan are not directly installed in the air outlet channel 1a. In this case, the heating component 2 can be placed at any position in the air outlet channel 1a without worrying that the heat emitted by the heating component 2 will have an adverse effect on the fan.

[0064] In this embodiment, the head assembly 100 adopts a heating component 2 with a heat-conducting fin structure 22. The heat-conducting fins increase the heat conduction speed on the heating element 21 and increase the heat exchange area between the air inlet and the heating component 2, thereby achieving the beneficial effect of improving the heat exchange efficiency between the heating element 21 and the air inlet. This results in lower energy consumption for the head assembly 100 and the ability to quickly reach the temperature required by the user.

[0065] Further, please refer to Figures 7 and 8. In one embodiment of this application, the blower module 1 includes a housing 11, a mounting structure 12, and a fan assembly 13. An air outlet channel 1a is formed inside the housing 11. The housing 11 is provided with an air outlet hole 11a that communicates with the air outlet channel 1a. The mounting structure 12 is disposed inside the air outlet channel 1a. The fan assembly 13 is connected to one end of the mounting structure 12. The heating element 21 and the heat-conducting fin structure 22 are connected to the other end of the mounting structure 12. The heat-conducting fin structure 22 is provided corresponding to the air outlet hole 11a.

[0066] In this embodiment, an air outlet channel 1a is formed inside the housing 11. The mounting structure 12 is connected to the housing 11 and located inside the air outlet channel 1a, providing a mounting base for the fan assembly 13 and the heating assembly 2. The mounting structure 12 is bowl-shaped and gradually expands along the direction close to the air outlet 11a. An annular gap is formed between the mounting structure 12 and the inner wall of the air outlet channel 1a to allow airflow to pass through. Because the mounting structure 12 is bowl-shaped and gradually expands along the direction close to the air outlet 11a, the gap between the mounting structure 12 and the inner wall of the air outlet channel 1a gradually decreases, achieving the effect of airflow concentration. This increases the airflow velocity after passing through the mounting structure 12, improving the wind force. Therefore, it can provide some assistance in overcoming the wind resistance of the heat-conducting fin structure 22.

[0067] The fan assembly 13 is installed at the center of the mounting structure 12. Specifically, the fan blade 132 in the mounting assembly is installed at the center of the end of the mounting structure 12 facing away from the air outlet 11a, and the heating assembly 2 is installed at the end of the mounting assembly facing the air outlet 11a. This allows the airflow to be heated and then leave the air outlet channel 1a directly through the air outlet 11a without passing through the fan assembly 13, preventing the fan assembly 13 from being overheated and overloaded. It can also carry away the heat generated by the fan assembly 13 itself.

[0068] Further, please refer to Figures 7, 8, 9 and 11. In one embodiment of this application, the housing 11 includes a rear housing 111 and a front cover 112. An air outlet channel 1a is formed inside the rear housing 111. The front cover 112 is connected to one end of the rear housing 111 and covers the heating assembly 2. The front cover 112 is provided with an air outlet 11a.

[0069] In this embodiment, the front cover 112 and the rear shell 111 are detachably connected, for example, by a snap-fit ​​groove and a snap-fit ​​protrusion, or by providing threads on the front cover 112 and a threaded groove on the side wall of the air outlet duct 1a of the rear shell 111, allowing the front cover 112 to be screwed into the rear shell 111, or by directly providing screw holes on the front cover 112 and the rear shell 111, connecting them with bolts. This detachable connection facilitates cleaning dust from inside the shell 11, preventing excessive dust accumulation that could reduce heat dissipation, and also allows for the replacement of damaged heating elements 21 without replacing the entire unit, thus reducing maintenance difficulty. The front cover 112 is connected to one end of the rear shell 111 and covers the heating element 2, protecting it from damage caused by accidental impacts or tipping.

[0070] Further, referring to Figures 7 and 9, in one embodiment of this application, a heat insulation pad 121 is provided between the heating component 2 and the mounting structure 12; and / or, the front cover 112 includes an outer ring 1121, an inner ring 1122 and a rib 1123 connecting the inner ring 1122 and the outer ring 1121, the inner ring 1122 and the outer ring 1121 are spaced apart to form an air outlet 11a, and the inner ring 1122 is connected to the mounting structure 12; and / or, the housing 11 also includes an air inlet hood 113, the air inlet hood 113 is connected to the end of the rear housing 111 away from the front cover 112 and communicates with the air outlet channel 1a, the air inlet hood 113 is circumferentially surrounded by an air inlet 113a, and a filter element 114 is provided inside the air inlet hood 113.

[0071] In this embodiment, a heat insulation pad 121 is provided between the heating component 2 and the mounting structure 12. The heat insulation pad 121 can be made of low thermal conductivity materials such as ceramic to prevent the mounting structure 12 from deforming due to heat. The front cover 112 includes an outer ring 1121, an inner ring 1122, and ribs 1123 connecting the inner ring 1122 and the outer ring 1121. The inner ring 1122 and the outer ring 1121 form air outlet holes 11a at intervals, that is, the air outlet holes 11a are distributed in a ring. When the airflow is blown out from the ring-shaped air outlet holes 11a, it will diffuse. Part of it diffuses towards the center of the ring, and the other part diffuses towards the outer periphery of the ring, thus expanding the air outlet area. Furthermore, since the area of ​​the air outlet hole 11a is smaller than the area of ​​the air outlet channel 1a, the airflow velocity increases, thereby increasing the wind force. The inner ring 1122 covers the heating component 2 to protect it. The inner ring 1122 is connected to the mounting structure 12. Both the fan assembly 13 and the heating assembly 2 are located on the mounting structure 12. Therefore, opening the front cover 112 allows the fan assembly 13 and the heating assembly 2 to be removed together for easy maintenance and dust removal. The housing 11 also includes an air inlet hood 113, which is connected to the end of the rear housing 111 opposite to the front cover 112 and communicates with the air outlet duct 1a. The air inlet hood 113 is circumferentially surrounded by air inlets 113a, which are configured with multiple small holes. With the same air inlet area, this can prevent debris from being drawn into the equipment and damaging the fan. The air inlet hood 113 is equipped with a filter element 114. The filter element 114 can be a filter screen or a filter cotton with multiple slits. The air inlet hood and the rear shell 111 are detachably connected. When a lot of dust accumulates on the filter element 114, the air inlet hood can be disassembled separately to clean or replace the filter element 114 without disassembling the whole machine, which improves the convenience of equipment maintenance.

[0072] Further, please refer to Figures 10 and 11. In one embodiment of this application, the fan assembly 13 includes a fan body 131 and a fan blade 132. The fan blade 132 includes an inner hub 1321, an outer hub 1322, an inner blade 1323, and an outer blade 1324. The inner hub 1321 is connected to the fan body 131. The outer hub 1322 is coaxially arranged with the inner hub 1321 and is sleeved on the outer periphery of the inner hub 1321. An air inlet channel is formed between the outer hub 1322 and the inner hub 1321. The outer blade 1324 is connected to the outer periphery of the outer hub 1322. The inner blade 1323 is disposed in the air inlet channel and connects the outer hub 1322 and the inner hub 1321.

[0073] In this embodiment, the outer blade 1324 is responsible for drawing in and expelling air, while the inner blade 1323 enhances the guidance and acceleration of airflow, reduces eddies and backflow, thereby increasing the overall airflow rate. Furthermore, the inner blade 1323 and outer blade 1324 can be staggered, meaning there is a phase difference between them. This design reduces airflow instability, making the airflow more continuous and stable, thus increasing the flow rate. This fan assembly 13 configuration significantly improves the airflow velocity and force within the outlet duct 1a. Based on this, a high-density thermally conductive fin structure 22 can be used, and a filter 114 can be installed at the air inlet 113a. The fan assembly 13 in this embodiment can provide a fast and powerful airflow, which can counteract the wind resistance caused by the thermally conductive fin structure 22 and the filter 114.
