[0025] The present invention provides a heating component 2 .

[0026] See also Figure 1 In one embodiment of the present invention, the heating component 2 includes a heating element 21 and a heat-conducting fin structure 22 . The heat-conducting fin structure 22 is extended along the circumference of the heating element 21 and is thermally connected to the heating element 21 .

[0027] In this embodiment, the heating element 21 adopts a specially designed heating structure. The specific structure is shown in the next embodiment. It can be understood that the heating element 21 can adopt a conventional resistance wire or heating tube. The heat-conducting fin structure 22 has a plurality of fin bodies 222 arranged at intervals. The plurality of fin bodies 222 arranged at intervals can be directly arranged on the heating element 21, or the plurality of fin bodies 222 arranged at intervals can be connected to one side of the connecting structure and connected to the heating element 21 through the connecting structure. It should be noted that the connecting structure can be arranged in a strip, circular, annular and linear shape, and the plurality of fins arranged at intervals can be arranged on the connecting structure in parallel or radially. When the heating element 21 adopts an annular shape, the plurality of fins arranged at intervals are arranged along the heating element 21 and distributed in an annular shape. When the heating element 21 adopts a linear shape, the plurality of fins arranged at intervals are arranged along the heating element 21 and distributed in a linear shape. The same is true for other shapes, so that the heating element 21 can be better fitted with the heat-conducting fin structure 22, so as to facilitate heat transfer and facilitate installation. The connecting structure can be connected to the heating element 21 by a fixed connection or a detachable connection.

[0028] The heating assembly 2 proposed in this embodiment can be arranged in the air outlet channel 1a of the head assembly 100, and is arranged on the air outlet path of the air outlet channel 1a. The heating assembly 2 of this embodiment adopts a heat-conducting connection between the heating element 21 and the heat-conducting fin structure 22, and uses the heat-conducting fins to increase the heat conduction speed on the heating element 21 and increase the heat exchange area between the incoming air and the heating assembly 2, thereby achieving the beneficial effect of improving the heat exchange efficiency between the heating element 21 and the incoming air.

[0029] For further information, see Figures 2 to 3 In one embodiment of the present invention, the heating element 21 includes a power connection member 211, a heating wire 212, an insulating heat-conducting layer 213 and a heat-conducting outer layer 214. The insulating heat-conducting layer 213 wraps the heating wire 212, and the heat-conducting outer layer 214 wraps the insulating heat-conducting layer 213. The power connection member 211 is connected to both ends of the heating wire 212 and extends into the insulating heat-conducting layer 213.

[0030] In this embodiment, the power connection piece 211 is made of conductive material for welding or plugging with the power line, for example, steel can be used and nickel-plated to ensure that the power connection piece 211 has a certain strength and corrosion resistance. The heating wire 212 can be made of a metal material with good heating performance when powered on, such as iron-chromium-aluminum alloy or nickel-chromium alloy. The heat-conducting outer layer 214 can be made of a tubular structure made of a metal or other material with good thermal conductivity, such as a copper tube or an aluminum tube. The heating wire 212 is accommodated 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.

[0031] The heating element 21 of this embodiment reduces the risk of electric leakage of the heating wire by wrapping the insulating heat-conducting layer 213 outside the heating wire 212, and arranges a heat-conducting outer layer 214 outside the insulating heat-conducting layer 213 to accommodate the insulating heat-conducting material of the insulating heat-conducting layer 213 and protect the heating wire 212 to prevent accidental damage to the heating wire 212. The heat-conducting outer layer 214 wraps the surrounding side of the insulating heat-conducting layer 213, and the heat-conducting outer layer 214 can be provided with flanges at the end to wrap the two end surfaces of the insulating heat-conducting layer 213, but not in contact with the electrical connection part 211. In addition, the insulating heat-conducting layer 213 isolates the heating wire 212 from the air to prevent the heating wire 212 from oxidation, further improving the service life of the heating wire 212.

[0032] For further information, see Figure 2In one embodiment of the present invention, the heating element 21 further includes an isolating member 215, which wraps the outer wall of the electrical connection member 211 and extends into the insulating heat-conducting layer 213. The isolating member 215 can block the gaps at both ends of the heat-conducting outer layer 214 to prevent the heating wire 212 from being oxidized or short-circuited or leaking. Therefore, the heat-conducting outer layer 214 can be connected and sealed with the surrounding side of the isolating member 215, or the end flange of the heat-conducting outer layer 214 can be used to wrap the end face of the isolating member 215, but it does not contact the electrical connection member 211. In this embodiment, the isolating member 215 can be made of ceramic material and made into a columnar or bead shape to be sealed at both ends of the heat-conducting outer tube. Ceramics are a good electrical insulating material that 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 the risk of short circuit and electric shock. In addition, ceramics are stable in properties at high temperatures and are not easy to melt or deform, so they help to improve the overall safety performance of the heating tube.

[0033] Further, see Figure 1 In one embodiment of the present invention, the heating component 2 further includes a temperature control switch 24, and the temperature control switch 24 is electrically connected to the heating wire.

[0034] In this embodiment, at least one of the electrical connections at both ends of the heating element 21 is electrically connected to the temperature control switch 24 and then connected to the power supply. After the electrical connections 211 at both ends of the heating element 21 are connected to the power supply, the heating wire 212 inside the heating element 21 generates heat, and the heat is conducted to the connected heat-conducting fin structure 22 through the internal insulating heat-conducting material and the metal high-heat material on the outer wall, so that the heat can be dissipated. The position of the temperature control switch 24 is fixed on the heat-conducting fin structure 22. 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 disconnected, 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 resume power, and the heating wire 212 will continue to generate heat. This can be repeated to prevent the heating component 2 from overheating and causing fire and other dangers; the temperature control switch 24 can be a bimetallic temperature control switch or a thermistor temperature control switch. The bimetallic temperature control switch uses two metal sheets with different expansion coefficients to combine together. When the temperature changes, the bimetallic strip will bend to varying degrees, thereby triggering the action of disconnecting the circuit. When the temperature drops, the bimetallic strip will restore the connection, so that the circuit is restored to the path; the thermistor temperature control switch uses the characteristic that the resistance of the thermistor changes with temperature. When the temperature rises, the resistance value gradually increases, causing the current in the circuit to decrease. When the set temperature is reached, the resistance value increases to block the current in the circuit, thereby triggering the action of disconnecting the circuit. When the temperature drops, the resistance also decreases, so that the circuit is restored to the path. The thermistor temperature control switch has the advantages of adjustable protection range, wide application range, convenient operation, and high pressure resistance. The temperature control switch can have a variety of structural forms. The present application does not limit the structural form of the temperature control switch. In addition, the heating component can be provided with a variety of types of temperature control switches, and multiple temperature control switches can be arranged in series to improve the safety performance of the heating component.

[0035] For further information, see Figures 4 to 6 In one embodiment of the present invention, 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 a plurality of fin bodies 222; a plurality of ribs 2221 are arranged at intervals on the fin body 222, and the ribs 2221 extend toward another adjacent fin body 222; and / or, the heating component 2 also includes a first temperature measuring element, which is heat-conductingly connected to the heating element 21 or the heat-conducting fin structure 22 to monitor the temperature of the heating component 2; and / or, the heating component 2 also includes a second temperature measuring element, which is used to monitor the outlet air temperature of the head assembly 100.

[0036] In this embodiment, the detachable connection between the thermal fin structure 22 and the heating element 21 can be achieved by snapping, setting slide grooves and slide rails, or setting bolts and screw holes. It should be noted that when achieving the detachable connection, it is necessary to retain a sufficient fitting area between the thermal fin structure 22 and the heating element 21 to ensure the heat exchange efficiency. The detachable connection method allows the thermal fin structure 22 to be removed for cleaning to prevent excessive dust accumulation from causing a decrease in the heat dissipation effect. The damaged heating element 21 can also be replaced without replacing the entire machine, thereby reducing the difficulty of maintenance.

[0037] The heat conducting fin structure 22 of this embodiment is an integrally formed structure. Figure 4 Taking the annular heat-conducting fin structure 22 as an example, the heat-conducting fin structure 22 has a strip-shaped heat-conducting plate, and a plurality of fin bodies 222 arranged at intervals are arranged on one side of the heat-conducting plate. The fin body structure 222 and the heat-conducting plate are an integrally formed structure, so that the connection strength between the fin body 222 and the heat-conducting plate is strengthened, and due to the integrally formed setting, there is no gap between the fin body 222 and the heat-conducting plate, which reduces the loss in the heat conduction process and improves the heat conduction efficiency. It should be noted that the above is only an exemplary example of the integrally formed setting through the annular heat-conducting fin structure 22, and should not be regarded as a limitation on the technical solution of the present invention.

[0038] In order to reduce wind resistance and increase the density of the fin body 222, the shape of the fin body 222 is relatively thin and easily deformed by external force. In order to strengthen the support between adjacent fin bodies 222, the thermal conductive fin structure 22 includes a plurality of fin bodies 222. A plurality of ribs 2221 are arranged at intervals on the fin body 222. The ribs 2221 extend toward another adjacent fin body 222. The ribs 2221 support the adjacent fin bodies 222, thereby improving the deformation resistance of the fin body 222 and ensuring sufficient ventilation area.

[0039] The heating component 2 also includes a first temperature measuring 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 measuring element can be connected to the display module for communication to display the temperature of the heating component 2 in real time, and issue a control instruction to adjust the heating temperature of the heating component 2 to improve the user experience.

[0040] The heating component 2 also includes a second temperature measuring element, which is used to monitor the outlet air temperature of the head component 100. In this embodiment, a second temperature measuring element is set in the air outlet direction of the head component 100, which can be set in the air duct of the head component 100 near the air outlet. The second temperature measuring element can monitor the blowing temperature in real time, and then the blowing temperature can be fed back to the control unit. The control unit can control the power of the heating element 21 through electronic components (such as thyristors), and then adjust the temperature of the air outlet, so that the air blown out of the air outlet at the same outlet wind speed can reach different temperatures, or the air blown out at different wind speeds can reach the same temperature. It should be noted that, in some embodiments, the purpose of setting the second temperature measuring element may be different from that of the first temperature measuring element. The first temperature measuring element is for safety protection, while the second temperature measuring element is to control the wind temperature of the air outlet in real time through wind temperature monitoring.

[0041] For further information, see Figure 1 , Figure 4 , Figure 5 and Figure 6 In one embodiment of the present invention, the heat-generating element 21 is arranged in a ring shape, and the heat-conducting fin structure 22 is sleeved on the outer periphery of the heat-generating element 21; or, the heat-conducting fin structure 22 includes a seat plate 221 and a plurality of fin bodies 222 arranged at intervals along the periphery of the seat plate 221, and the heat-generating element 21 is connected to the seat plate 221; or, the heat-generating element 21 is arranged in a straight line shape, the heat-conducting fin structure 22 is connected to the side wall of the heat-generating element 21, and is extended along the length direction of the heat-generating element 21.

[0042] In the first embodiment of the present invention, the heating element 21 is arranged in an annular shape, the heat-conducting fin structure 22 includes a plurality of 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 plurality of fin bodies 222 are radially spaced on the outer peripheral wall of the annular connecting plate. The heating component 2 of the present invention can adapt to most shapes of air outlet channels 1a, and air can flow in the middle of the annular shape, and the airflow is relatively large.

[0043] In another scheme of the present embodiment, the heat-conducting fin structure 22 includes a seat plate 221 and a plurality of fin bodies 222 spaced apart along the periphery of the seat plate 221. The heating element 21 is connected to the seat plate 221. The seat plate 221 has a strong bearing capacity and can be connected with more fin bodies 222 of larger size, thereby increasing the heat exchange area and improving the heat exchange efficiency between the heating component 2 and the incoming air.

[0044] In another scheme of the present embodiment, 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 is extended along the length direction of the heating element 21. In this way, the air outlet 11a can be designed in a strip shape, which can heat the air in a larger range and can be applied to vertical or horizontal heating equipment to improve the practicality of the heating component 2.

[0045] For further information, see Figure 7 , Fig.11 and Fig.12 In one embodiment of the present invention, the heat generating 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 element 23, the heat-conducting fixing element 23 is detachably connected to the head assembly 100, and the heat-conducting fin structure 22 and the heat generating element 21 are respectively connected to opposite sides of the heat-conducting fixing element 23.

[0046] In the present embodiment, the heating element 21 or the heat-conducting fin structure 22 is provided with a connecting convex plate, and the connecting convex plate is provided with a through hole, which can be connected to the head assembly 100 by bolts. It should be noted that the number of the connecting convex plate and the through hole can be increased as needed, and 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 setting of the connecting convex plate and the through hole, and can also be achieved by setting a slide rail and a slide groove, a clamping structure, etc. The detachable connection method allows the heat-conducting fin structure 22 to be disassembled for cleaning, preventing excessive dust accumulation from causing a decrease in the heat dissipation effect, and the damaged heating element 21 can also be replaced without replacing the entire machine, thereby reducing the difficulty of maintenance. The heating element 21 and the heat-conducting fin structure 22 can also be connected by a heat-conducting fixing member 23, and the heat-conducting fixing member 23 can be a welding material or a heat-resistant glue, etc.

[0047] The present invention also provides a head assembly 100, which can be applied to but not limited to hair dryers, heaters and other blowing devices.

[0048] See also Figure 7 , Figure 8 and Fig.13 In one embodiment of the present invention, the head assembly 100 includes a blowing module 1 and a heating assembly 2 as in any one of the above-mentioned embodiments, an air outlet channel 1a is formed in the blowing module 1, and the heating assembly 2 is arranged in the air outlet channel 1a and on the air outlet path of the blowing module 1.

[0049] In this embodiment, the head assembly 100 includes a blowing module 1 and a heating assembly 2. The blowing module 1 is composed of a shell 11, a mounting structure 12 and a fan assembly 13. An air outlet channel 1a is formed in the shell 11, and an air outlet hole 11a is provided. The shell 11 can be cylindrical, and the openings at both ends of the cylinder can be used as the air inlet 113a and the air outlet 11a. A straight air outlet channel 1a can be correspondingly provided in the cylindrical shell 11 to avoid corners in the blowing path, improve the smoothness of the gas flow, and reduce the pressure of the fan assembly 13. It is also possible to reopen the strip-shaped air inlet 113a and the air outlet 11a on the side of the cylinder for application in horizontal or vertical heating equipment. The strip-shaped air outlet allows the user to feel a wider range of wind force, thereby improving the practicality of the head assembly 100.

[0050] The fan assembly 13 is fixed in the housing 11 through the mounting structure 12, while the heating assembly 2 is located in the air outlet channel 1a, just on the air outlet path. The heat-conducting fin structure 22 of the heating assembly 2 is arranged corresponding to the air outlet hole 11a, so that the hot air can leave the air outlet channel 1a as soon as possible, reducing heat loss. In addition, the heat-conducting fin structure 22 only needs to be arranged corresponding to the air outlet hole 11a, which can reduce the volume of the heat-conducting fin structure 22, reduce wind resistance, make the airflow in the air outlet channel 1a smoother, and reduce the material cost of the heat-conducting fin structure 22, which is conducive to reducing redundant design and reducing structural costs.

[0051] It should be noted that the blowing module 1 can also adopt a blowing structure without fan blades 132, that is, the fan blades 132 are hidden designs, and the fan blades 132 and the fan may not be directly arranged in the air outlet channel 1a. At this time, the heating component 2 can be arranged at any position of the air outlet channel 1a without having to worry about the heat emitted by the heating component 2 causing adverse effects on the fan.

[0052] The head assembly 100 of this embodiment adopts a heating assembly 2 with a heat-conducting fin structure 22. The heat-conducting fins are used to increase the heat conduction speed on the heating element 21 and increase the heat exchange area between the air intake and the heating assembly 2, thereby achieving the beneficial effect of improving the heat exchange efficiency between the heating element 21 and the air intake, so that the energy consumption of the head assembly 100 is low and the temperature required by the user can be quickly reached.

[0053] For further information, see Figure 7 and Figure 8In one embodiment of the present invention, the blowing module 1 includes a shell 11, a mounting structure 12 and a fan assembly 13. An air outlet channel 1a is formed in the shell 11. The shell 11 is provided with an air outlet hole 11a connected to the air outlet channel 1a. The mounting structure 12 is arranged in 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 arranged corresponding to the air outlet hole 11a.

[0054] In this embodiment, an air outlet channel 1a is formed in the housing 11, and the mounting structure 12 is connected to the housing 11 and is located in the air outlet channel 1a, and is used to provide an installation basis for the fan assembly 13 and the heating assembly 2. The mounting structure 12 is bowl-shaped and gradually expands in the direction close to the air outlet hole 11a, and an annular gap is formed between the mounting structure 12 and the inner wall of the air outlet channel 1a for airflow to pass through. Moreover, since the mounting structure 12 is bowl-shaped and gradually expands in the direction close to the air outlet hole 11a, that is, the gap between the mounting structure 12 and the inner wall of the air outlet channel 1a gradually decreases, the effect of gathering wind is achieved, so that the flow velocity of the airflow after passing through the mounting structure 12 is increased, and the wind force is improved, so that it can provide a certain amount of assistance for overcoming the wind resistance of the heat-conducting fin structure 22.

[0055] 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 that is away from the air outlet 11a, and the heating assembly 2 is installed at the end of the mounting assembly that is facing the air outlet 11a. In this way, the airflow can be heated and directly pass through the air outlet 11a to leave the air outlet channel 1a without passing through the fan assembly 13, thereby preventing the fan assembly 13 from being overloaded by heat and also taking out the heat generated by the fan assembly 13 itself.

[0056] For further information, see Figure 7 , Figure 8 , Fig. 9 and Fig.11 In one embodiment of the present invention, the housing 11 includes a rear shell 111 and a front cover 112. An air outlet channel 1a is formed in the rear shell 111. The front cover 112 is connected to one end of the rear shell 111 and covers the heating component 2. The front cover 112 is provided with an air outlet hole 11a.

[0057] In this embodiment, the front cover 112 is detachably connected to the rear shell 111, for example, by connecting with a snap-in groove and a snap-in protrusion, or by providing a thread on the front cover 112, and providing a thread groove on the side wall of the air outlet channel 1a of the rear shell 111, so that the front cover 112 can be screwed into the rear shell 111 through the thread, or by directly providing screw holes on the front cover 112 and the rear shell 111, and connecting the front cover 112 and the rear shell 111 through bolts. The detachable connection between the front cover 112 and the rear shell 111 facilitates the cleaning of dust inside the housing 11, prevents excessive dust accumulation from causing a decrease in the heat dissipation effect, and can also replace a damaged heating element 21 without replacing the entire unit, thereby reducing the difficulty of maintenance. The front cover 112 is connected to one end of the rear shell 111 and covers the heating component 2, so as to protect the heating component 2 and prevent damage to the heating component 2 caused by accidental collision or tipping.

[0058] For further information, see Figure 7 and Fig. 9 In one embodiment of the present invention, a heat insulating 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 shell 11 also includes an air inlet cover 113, the air inlet cover 113 is connected to the end of the rear shell 111 away from the front cover 112, and is connected to the air outlet channel 1a, the air inlet cover 113 is circumferentially provided with an air inlet 113a, and a filter element 114 is provided inside the air inlet cover 113.

[0059] In this embodiment, a heat insulating pad 121 is provided between the heating component 2 and the mounting structure 12. The heat insulating pad 121 can be made of low thermal conductivity materials such as ceramics to prevent the mounting structure 12 from being deformed by 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 are spaced to form an air outlet 11a, that is, the air outlet 11a is distributed in an annular shape. When the airflow is blown out from the annularly distributed air outlet 11a, it will diffuse, with one part diffusing to the center of the annular shape and the other part diffusing to the outer periphery of the annular shape, so that the air outlet area is expanded. Moreover, since the area of ​​the air outlet 11a is reduced relative to 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 the heating component 2. The inner ring 1122 is connected to the mounting structure 12, and the fan assembly 13 and the heating assembly 2 are both arranged on the mounting structure 12, so when the front cover 112 is opened, the fan assembly 13 and the heating assembly 2 can be taken out together, which is convenient for maintenance and dust removal. The housing 11 also includes an air inlet cover 113, which is connected to the end of the rear shell 111 away from the front cover 112 and is connected to the air outlet channel 1a. The air inlet cover 113 is circumferentially surrounded by an air inlet 113a, and the air inlet 113a is set as a plurality of small holes. Under the condition of the same air inlet area, it can prevent debris from being drawn into the device and damaging the fan. A filter element 114 is provided in the air inlet cover 113. The filter element 114 may be a filter mesh or filter cotton with multiple gaps, etc. The air inlet cover is detachably connected to the rear shell 111. When a lot of dust accumulates on the filter element 114, the air inlet cover can be disassembled separately to clean or replace the filter element 114 without disassembling the entire machine, thereby improving the convenience of equipment maintenance.

[0060] For further information, see Figure 10 to Figure 11 In one embodiment of the present invention, the fan assembly 13 includes a fan body 131 and fan blades 132, the fan blades 132 include an inner hub 1321, an outer hub 1322, inner blades 1323 and outer blades 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 blades 1324 are connected to the outer periphery of the outer hub 1322, and the inner blades 1323 are arranged in the air inlet channel and connect the outer hub 1322 and the inner hub 1321.

[0061] In this embodiment, the outer blades 1324 are responsible for inhaling and discharging air, while the inner blades 1323 can enhance the guidance and acceleration of the airflow, reduce eddy currents and backflows, and thus improve the overall air flow. In addition, the inner blades 1323 and the outer blades 1324 can be arranged in a staggered manner, that is, the inner blades 1323 and the outer blades 1324 will have a phase difference, which means that they do not arrive at the same position at the same time. This design can reduce the instability of the airflow, making the airflow more continuous and stable, thereby increasing the flow rate. The arrangement of this fan assembly 13 greatly improves the flow rate and wind force of the airflow in the air outlet channel 1a. Based on this, a high-density heat-conducting fin structure 22 can be used and a filter 114 can be arranged at the air inlet 113a. The fan assembly 13 of this embodiment can provide an airflow with a fast flow rate and strong wind force, which can offset the wind resistance caused by the heat-conducting fin structure 22 and the filter 114.
