DETAILED DESCRIPTION

[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Hereinafter, a heating device 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0043] like Figure 1-Figure 18 As shown, the heating device 1 according to the embodiment of the present invention may include a head assembly 10 and a body assembly 20 .

[0044] For example, the heating device 1 is a small radiant sun heater, and the heating device 1 includes a head assembly 10 and a body assembly 20, the body assembly 20 is suitable for being supported on the ground, the head assembly 10 is arranged at the upper end of the body assembly 20 and can rotate relative to the body assembly 20 (up and down directions such as Figure 1As shown). The head assembly 10 may include a head shell 300, a reflector 200 and a heating device 100. The head shell 300 is connected to the body assembly 20. The reflector 200 is disposed in the head shell 300. The reflector 200 has a cover cavity 201. The heating device 100 is disposed in the cover cavity 201. The heating device 100 may be a light-emitting heating element, for example, the heating device 100 may be a heating tube. The radiant heat of the heating device 100 during operation can be evenly irradiated to the area to be heated after being reflected by the wall of the cover cavity 201.

[0045] In some embodiments, the head assembly 10 may include a head housing 300, a reflector 200, and a heating device 100. The head housing 300 has a hollow cavity 301 and a mounting cavity 302 surrounding the hollow cavity 301. The two ends of the hollow cavity 301 in the length direction are open. For example, the hollow cavity 301 is a cylindrical cavity, and the two ends of the hollow cavity 301 in the axial direction are open. This can not only improve the fashion sense of the heating device 1 and improve the user's sensory experience, but also the airflow can pass through the head assembly 10 through the hollow cavity 301, which is convenient for heat dissipation of the head assembly 10 and avoid the danger caused by the head assembly 10 being overheated.

[0046] The reflector 200 is disposed in the installation cavity 302, and the shape of the reflector 200 is adapted to the shape of the installation cavity 302. For example, the installation cavity 302 is an annular cavity surrounding the hollow cavity 301, and the middle part of the reflector 200 has an escape opening for escaping the hollow cavity 301. The reflector 200 has a cavity 201, and the heating device 100 is disposed in the cavity 201. The head assembly 10 is rotatably disposed on the body assembly 20.

[0047] According to the heating device 1 of the embodiment of the present invention, by providing a hollow cavity 301 and opening both ends of the hollow cavity 301 to form an opening, not only can the fashion sense of the heating device 1 be improved, and the sensory experience of the user can be improved, but also the airflow can pass through the hollow cavity 301 through the head assembly 10, so as to facilitate the heat dissipation of the head assembly 10 and avoid the danger caused by the head assembly 10 being overheated. It can also reduce the distance between the front side protective net 314 of the head shell 300 and the heating device 100, thereby reducing the protrusion of the protective net 314, thereby reducing the thickness of the protective net 314 and making the thickness of the head assembly 10 thinner.

[0048] At the same time, the user can use the hollow cavity 301 as a handle to facilitate the user to move and carry the heating device 1.

[0049] Furthermore, by disposing the heating device 100 in the cover cavity 201, the thickness of the reflective cover 200 can be reduced, so that the reflective cover 200 can be made very thin, and the thickness of the head assembly 10 can be further thinned.

[0050] Therefore, the heating device 1 according to the embodiment of the present invention has the advantages of hollow, ultra-thin design, fashionable and beautiful appearance, etc.

[0051] The following describes a heating device 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0052] In some specific embodiments of the present invention, Figure 1-Figure 18 As shown, the heating device 1 according to the embodiment of the present invention may include a head assembly 10 and a body assembly 20 .

[0053] In some embodiments, Figure 6 As shown, the head housing 300 may include a rear housing 320, a front housing 310 and a middle ring cylinder 330 (the front and rear directions are as shown in FIG. Figure 2 As shown in the figure, the rear shell 320 has a first through hole 321, and the first through hole 321 is formed in the middle of the rear shell 320. The front shell 310 has a second through hole 311, and the second through hole 311 corresponds to the first through hole 321 in front and back, and the second through hole 311 is formed in the middle of the front shell 310, and the outer edge of the front shell 310 is connected to the rear shell 320. The middle ring cylinder 330 is respectively connected to the rear shell 320 and the front shell 310 and is arranged between the rear shell 320 and the front shell 310. The middle ring cylinder 330 defines a hollow cavity 301, and the hollow cavity 301 is respectively connected to the first through hole 321 and the second through hole 311. The middle ring cylinder 330, the front shell 310 and the rear shell 320 define an installation cavity 302. This facilitates the formation of the hollow cavity 301 and the installation cavity 302, facilitates the processing and setting of the head shell 300, and facilitates the assembly and molding of the head assembly 10.

[0054] For example, the rear shell 320 has a circular first through hole 321, and the first through hole 321 is formed in the middle of the rear shell 320. The front shell 310 has a circular second through hole 311, and the second through hole 311 corresponds to the first through hole 321 in front and back, and the second through hole 311 is formed in the middle of the front shell 310. The outer edge of the front shell 310 is detachably connected to the outer edge of the rear shell 320. The middle ring cylinder 330 is arranged in the middle of the head shell 300 and arranged between the rear shell 320 and the front shell 310. The rear end of the middle ring cylinder 330 is connected to the rear shell 320, and the front end of the middle ring cylinder 330 is connected to the front shell 310. The middle ring cylinder 330 is formed into a cylindrical structure, and the middle part of the middle ring cylinder 330 defines a hollow cavity 301, and the rear end of the hollow cavity 301 is connected to the first through hole 321, and the front end of the hollow cavity 301 is connected to the second through hole 311, so as to realize a flow passage connected to the external environment. The outer side wall of the middle ring cylinder 330, the rear side wall of the front shell 310 and the front side wall of the rear shell 320 jointly define the installation cavity 302. This facilitates the formation of the hollow cavity 301 and the installation cavity 302, facilitates the processing and setting of the head housing 300, and facilitates the assembly and molding of the head assembly 10.

[0055] Specifically, Figure 6As shown, the side wall of the middle ring tube 330 has a first ventilation hole 331 that penetrates along the thickness direction, and the first ventilation hole 331 is used to connect the hollow cavity 301 and the cover cavity 201. In this way, the air in the hollow cavity 301 can flow into the cover cavity 201 through the first ventilation hole 331 to dissipate heat from the structure in the cover cavity 201, reduce the problems in the cover cavity 201, avoid the temperature in the cover cavity 201 being too high and affecting the service life of the head assembly 10, and avoid the risk of burns caused by the user accidentally touching the head assembly 10. In other words, the first ventilation hole 331 can introduce new cold air from the outside to reduce the temperature of the whole machine.

[0056] Specifically, the upper side wall of the middle ring tube 330 is formed with a first ventilation hole 331 that penetrates along the thickness direction. The first ventilation hole 331 can be a circular hole. The first ventilation hole 331 is formed in multiple numbers. The multiple first ventilation holes 331 form multiple hole rows arranged along the axial direction of the middle ring tube 330. The multiple hole rows are arranged at intervals along the circumference of the middle ring tube 330.

[0057] Alternatively, if Figure 6 As shown, the upper wall of the hollow cavity 301 is provided with a heat-insulating rib 332 protruding toward the middle of the hollow cavity 301. In this way, when the user uses the hollow cavity 301 as a handle, the heat-insulating rib 332 can be used to block the user's palm and the wall of the hollow cavity 301, so that the palm is separated from the wall of the hollow cavity 301 by a certain distance and does not directly contact, thereby preventing the palm from directly contacting the wall of the hollow cavity 301 with an excessively high temperature and causing burns.

[0058] Furthermore, the heat insulating rib 332 extends along the axial direction of the middle ring tube 330. This facilitates the processing and setting of the heat insulating rib 332, facilitates the user's palm to smoothly extend into the hollow cavity 301 to cooperate with the heat insulating rib 332, and further facilitates the protection of the user to prevent the user from being scalded when using the hollow cavity 301 as a handle.

[0059] Specifically, there may be multiple insulation ribs 332, which are spaced apart along the circumference of the hollow cavity 301, and the insulation ribs 332 are staggered with the first ventilation hole 331 to avoid blocking the first ventilation hole 331.

[0060] In some examples, such as Figure 4As shown, the front shell 310 may include an outer shell cover 312, a middle ring cover 313 and a protective net 314. The outer shell cover 312 is formed as a circular annular clamping member. The outer shell cover 312 is connected to the rear shell 320, and the outer shell cover 312 has a first avoidance hole 3121. The middle ring cover 313 is connected to the middle ring cylinder 330, and the middle ring cover 313 defines a second through hole 311. The outer edge of the protective net 314 is clamped between the reflector 200 and the outer shell cover 312, and the inner edge of the protective net 314 is clamped between the middle ring cover 313 and the middle ring cylinder 330. The middle part of the protective net 314 extends out of the first avoidance hole 3121, that is, the protective net 314 is exposed from the area between the first avoidance hole 3121 and the second through hole 311. This not only facilitates the processing and manufacturing of the front shell 310, but also further facilitates the assembly and molding of the head assembly 10.

[0061] For example, the outer shell cover 312 is formed as a circular annular clamping member, the outer edge of the outer shell cover 312 is clamped and connected to the outer edge of the rear shell 320, and the middle part of the outer shell cover 312 has a first avoidance hole 3121 with a large diameter. The middle ring cover 313 is a circular annular clamping member, the middle ring cover 313 is clamped and connected to the front end of the middle ring cylinder 330, and the middle part of the middle ring cover 313 defines a second through hole 311. The protective net 314 is formed as an annular mesh structure, the outer edge of the protective net 314 is clamped between the reflector 200 and the outer shell cover 312, the inner edge of the protective net 314 is clamped between the middle ring cover 313 and the middle ring cylinder 330, and the middle part of the protective net 314 protrudes toward the front and is exposed from the area between the first avoidance hole 3121 and the second through hole 311. This not only facilitates the processing and manufacturing of the front shell 310, but also further facilitates the assembly and molding of the head assembly 10.

[0062] Furthermore, if Figure 6 As shown, the front end of the reflector 200 may have an air guide port 202 connected to the cover cavity 201, and the first avoidance hole 3121 is located outside the air guide port 202 in the radial direction of the outer shell cover 312. In this way, the first avoidance hole 3121 can avoid the air guide port 202, so that the radiant heat and hot air can be smoothly output from the air guide port 202. If the first avoidance hole 3121 is located inside the air guide port 202, an area that is not convenient for air flow will appear between the inner edge of the outer shell cover 312 and the reflector 200, where the temperature will rise sharply, and even damage to the outer shell cover 312 and other structures.

[0063] For example, the reflector 200 is formed into a flared cover body with a gradually increasing cross-sectional area from the back to the front, the front end of the reflector 200 is opened to form a circular air guide port 202, and the first avoidance hole 3121 can be arranged concentrically with the air guide port 202, and the aperture of the first avoidance hole 3121 is larger than the aperture of the air guide port 202. Preferably, in the radial direction of the outer shell cover 312, the distance between the first avoidance hole 3121 and the air guide port 202 is greater than or equal to 7 mm. In this way, the first avoidance hole 3121 can avoid the air guide port 202, so that the radiant heat and hot air can be smoothly output from the air guide port 202. If the first avoidance hole 3121 is located on the inner side of the air guide port 202, an area that is not convenient for air flow will appear between the inner edge of the outer shell cover 312 and the reflector 200, where the temperature will rise sharply, and even damage to the structure such as the outer shell cover 312 will be caused.

[0064] In some embodiments, Figure 7 and Fig.10 As shown, the reflector 200 may include a cover body 210 and a mounting ring seat 220, the cover body 210 defines a cover cavity 201 and a second avoidance hole 211, and the second avoidance hole 211 is communicated with the cover cavity 201. The mounting ring seat 220 is arranged in the cover cavity 201 and is connected to the cover body 210, and the heating device 100 is formed as an annular tube, and the heating device 100 is suitable for being sleeved on the outer side of the mounting ring seat 220. In this way, it is convenient for the reflector 200 to reflect the radiant heat of the heating device 100, so that the heat can evenly heat the area to be heated. The side wall of the mounting ring seat 220 may have a second vent 221. In this way, it is convenient for cold air to flow through the first vent 331 and the second vent 221 and enter the cover cavity 201 from the hollow cavity 301.

[0065] Optionally, the second ventilation hole 221 is a circular hole, there are a plurality of second ventilation holes 221 , and the plurality of second ventilation holes 221 form a hole group extending along the circumferential direction of the mounting ring seat 220 .

[0066] In some examples, such as Fig. 9 As shown, a ring-shaped baffle 230 is provided at the front end of the mounting ring seat 220 , and the baffle 230 is provided in front of the heating device 100 to shield the heating device 100 .

[0067] For example, the cover body 210 defines a cover cavity 201, and a second avoidance hole 211 is provided in the middle of the rear end of the cover body 210. The mounting ring seat 220 is disposed in the cover cavity 201 and connected to the cover body 210 at the second avoidance hole 211. A bracket 222 is installed on the outer side of the mounting ring seat 220. The heating device 100 is formed as an annular tube. The heating device 100 is suitable for being sleeved on the outer side of the mounting ring seat 220 and fixed on the bracket 222. The bracket 222 is multiple and is arranged at intervals along the circumference of the mounting ring seat 220. In this way, the reflector 200 can reflect the radiant heat of the heating device 100, so that the heat can evenly heat the area to be heated.

[0068] Alternatively, if Fig. 9 As shown, the head assembly 10 may further include a temperature limiter 400, at least a portion of which is disposed in the housing cavity 201 and above the heating device 100. It should be understood here that the temperature limiter 400 is a temperature-sensitive controller that makes the temperature lower or higher than a certain value under normal working conditions. For example, the temperature limiter 400 detects the temperature of the air in the reflector 200 under normal working conditions, so that the operating temperature in the reflector 200 is lower than the first preset temperature value, and when the temperature in the reflector 200 increases abnormally, the heating device 1 can be promptly controlled to stop working.

[0069] Since the temperature of the area in the cover cavity 201 is relatively high during normal operation, and the temperature changes greatly when covered by cotton cloth, the temperature limiter 400 can accurately and effectively detect the air temperature in the reflective cover 200, and timely control the heating device 1 to stop working when the temperature in the reflective cover 200 is too high. In this way, the temperature rise problem that occurs when the reflective cover 200 of the heating device 1 is covered can be effectively solved, and the damage of the parts of the heating device 1 caused by the excessive temperature in the reflective cover 200 can be avoided, thereby preventing the occurrence of fire.

[0070] For example, the reflector 200 may have a reflective portion formed by a specific parabola segment rotating around a certain central axis, and the heating device 100 is disposed in an area adjacent to the focus of the parabola. The temperature limiter 400 is disposed in an area above the heating device 100. Since hot air has a low density and floats upward, the air temperature in the area above the heating device 100 in the reflector 200 is relatively high, and the temperature change in the area is also relatively large when covered with cotton cloth.

[0071] Furthermore, if Fig.10As shown, the reflector 200 may have a mounting hole 203, the shape of which is adapted to the stopper, and a portion of the temperature limiter 400 may be disposed in the mounting cavity 302 and another portion may extend into the cover cavity 201 through the mounting hole 203. This facilitates the installation and connection of the temperature limiter 400, and facilitates the temperature limiter 400 to accurately detect the temperature in the cover cavity 201, thereby ensuring the detection effect of the temperature limiter 400.

[0072] For example, in some examples, a single temperature limiter 400 can be arranged on the symmetry line extending along the vertical direction of the reflector 200, and the temperature limiter 400 is arranged in the cover cavity 201 adjacent to the upper edge of the reflector 200. In this way, the detection sensitivity of the temperature limiter 400 to the high-temperature air in the cover cavity 201 can be improved, and the detection accuracy and reliability of the temperature limiter 400 can be improved. In other examples, there can be multiple temperature limiters 400, and multiple temperature limiters 400 can be symmetrically arranged on both sides of the symmetry line extending along the vertical direction of the reflector 200, and multiple temperature limiters 400 are arranged in the cover cavity 201 adjacent to the upper edge of the reflector 200. For example, in a plane perpendicular to the axis of the reflector 200, the angle between the line connecting the center point of each temperature limiter 400 and the center point of the reflector 200 and the symmetry line extending along the vertical direction of the reflector 200 can be 10-30 degrees, specifically 20 degrees. This makes it easy to detect the areas on both sides of the symmetry line in the housing cavity 201 of the reflector 200, so as to accurately and reliably measure and control the temperature of the areas on both sides.

[0073] In some embodiments, Figure 2 As shown, the fuselage assembly 20 may include a base 21, a first column 22, and a second column 23, wherein the first column 22 is detachably connected to the base 21. The second column 23 is detachably connected to the first column 22, and the head assembly 10 is rotatably disposed on the second column 23, and a wire passage is defined between the first column 22 and the second column 23. This not only facilitates the disassembly and assembly of the fuselage assembly 20, and facilitates the transportation and carrying of the heating device 1, but also allows the wiring harness such as the power cord to be routed through the wire passage, and no threading is required during assembly, which not only facilitates the assembly operation, but also facilitates the simplification of the structure of the fuselage assembly 20.

[0074] In some optional embodiments, the body assembly 20 further includes a positioning plate 24, which is detachably disposed on the second column 23, and the positioning plate 24 is provided with a guide structure 241 for positioning and guiding the installation of the head assembly 10. In this way, the guide structure 241 can be used to position and guide the installation of the head assembly 10, especially to position and guide the installation of the rear shell 320 of the head assembly 10, so as to facilitate the smooth installation of the rear shell 320.

[0075] In some specific embodiments, the positioning plate 24 is provided with a snap-fit ​​structure 244, which is suitable for snapping and cooperating with the second column 23. This facilitates the assembly and forming of the positioning plate 24, and the positioning plate 24 can be installed and fixed without fastening structural parts such as screws, thereby improving the assembly efficiency of the heating device 1.

[0076] In some specific embodiments, the positioning plate 24 is provided with a limiting structure 242 and a positioning groove 243 for positioning the rotation position of the head assembly 10, and the limiting structure 242 and the positioning groove 243 are respectively suitable for cooperating with the second column 23. It should be understood here that the limiting structure 242 and the positioning groove 243 are two independent positioning structures, and both positioning structures can be used to limit the rotation angle of the rear shell 320. In this way, a double-layer positioning guarantee can be formed. When one of the positioning structures fails, the other positioning structure can still effectively position the head assembly 10, which is convenient for improving the reliability of the rotation positioning of the head assembly 10 and improving the working stability of the heating device 1.

[0077] In some specific examples, such as Fig.14 As shown, the second column 23 includes a column body, a positioning push rod 231 and a spring 232, and the fuselage assembly 20 also includes a positioning plate 24, which is detachably arranged on the column body. The positioning push rod 231, the spring 232 and the positioning plate 24 can cooperate to realize the positioning of the head assembly 10 at different positions. Further, the positioning plate 24 includes a guide structure 241 for positioning and guiding the installation of the head assembly 10, which is convenient for the installation of the rear shell 320. The positioning plate 24 includes a limiting structure 242 and a positioning groove 243 for positioning the rotation position of the head assembly 10. The limiting structure 242 can cooperate with the column body, and the positioning push rod 231 can cooperate with the positioning groove 243. The limiting structure 242 and the positioning groove 243 respectively form two independent positioning structures with the corresponding matching structures. Both positioning structures can be used to limit the rotation angle of the rear shell 320. The positioning plate 24 is further provided with a snap-fit ​​structure 244 , which can be snap-fitted with the second column 23 .

[0078] Specifically, a knob structure and a base fixing hole are provided on the first column 22 , which facilitates the installation and removal of the base 21 .

[0079] According to some specific embodiments of the present invention, the heating device 100 is a heating tube, and the heating tube 100 may include a heating part, which can radiate heat when working, and the heating part is suitable for extending along the arc segment. For example, the heating part can extend to a superior arc segment larger than a semicircle, or it can extend to a inferior arc segment smaller than a semicircle. It should be understood here that the heating part is a part of the structure of the heating tube 100, and the heating part is regarded as a plane line segment structure ignoring the radius when describing. The reflector 200 can be covered on the heating tube 100 to reflect the radiant heat emitted by the heating tube 100, so that it can be evenly irradiated to the area to be heated. The reflector 200 can be provided with a reflector, which is a part of the structure of the reflector 200, and the reflector can reflect the radiant heat emitted by the heating tube 100 and irradiate the radiant heat to the heated area. The cross section of the reflector can be a parabola segment, and the line connecting the foci of the parabola is suitable for extending along the extension direction of the heating part and being arranged adjacent to the heating part. In other words, the foci of the parabola in the cross section of the reflector can be connected as an imaginary line, and the heating tube is arranged near the imaginary line. It should be understood here that, in the description, the cross-sectional shape of the reflecting portion is regarded as a planar line segment structure with the thickness ignored.

[0080] The heating part is formed as a circular tube, which extends along the superior arc segment of the circle. In the cross section of the reflecting part perpendicular to its length direction, the distance between the center point of the heating part and the focus of the parabola can be less than or equal to 10 mm. In this way, the positional relationship between the heating part and the reflecting part can be accurately defined, so that the heating part can be set near the focus of the parabola of the reflecting part, so that the reflector 200 can effectively reflect the radiation energy emitted by the heating part, emit substantially parallel and uniform energy, and improve the heating comfort.

[0081] The parabola segment may include a first line segment located on one side of the parabola vertex and a second line segment located on the other side of the parabola vertex, so that the reflector can reflect the radiation energy emitted by the heating portion on both sides of the heating portion, thereby improving the reflection efficiency of the reflector. It can be understood here that the line connecting the vertex of the parabola and the focus of the parabola is the symmetry axis of the parabola, and at least a portion of the first line segment and the second line segment are symmetrically arranged about the symmetry axis.

[0082] The reflector 200 may be a closed annular cover, the parabola segment may include a first line segment located outside the vertex of the parabola and a second line segment located inside the vertex of the parabola, the length of the first line segment may be greater than the length of the second line segment, the heating portion is arranged at the focus of the parabola, and the outer edge of the second line segment defines a mounting through hole in the middle of the reflector 200. This not only facilitates the installation of the heating tube 100 and makes the appearance of the heating device 1 fashionable, but also maximizes the reflection area of ​​the reflector 200.

[0083] The focus of the parabola can be located inside the reflector. In this way, the reflector 200 can be made very thin, making the thickness of the whole device thinner. The axial dimension of the reflector 200 can be 40-60 mm, for example, the axial dimension of the reflector 200 can be 50 mm. The curve equation of the parabola can be y=0.00694444444x 2 In this way, the shape of the reflecting part can be accurately defined, which not only facilitates ensuring the reflecting effect of the reflecting part, but also allows the focus of the parabola to be set at a suitable position inside the reflecting cover 200 .

[0084] The material of the reflector 200 can be aluminum. This not only ensures the reflective effect and working stability of the reflector 200, but also facilitates the processing and manufacturing of the reflector 200. The reflector 200 is integrally formed from aluminum. The reflector portion is formed by a specific parabola segment rotating around a certain central axis, so the inner surface of the reflector portion can be formed into a smooth curved surface. After the reflector 200 is processed and formed, the inner surface of the reflector portion is anodized. The heating portion can be formed into a ring tube with an opening on the lower side, and a lead end connected to the heating portion can be provided at the opening of the heating portion. In this way, the heating tube 100 can be connected to an external power supply device through the lead end to provide electrical energy to the heating portion so that it can work normally. The heating portion can be a carbon fiber heating element. In this way, the outer surface temperature of the heating portion can be higher and the radiation effect is better.

[0085] According to a specific embodiment of the present invention, the heating device 1 may include a head assembly 10 and a body assembly 20. The heating device 1 is a small radiant sunshade, and the heating device 1 includes a head assembly 10 and a body assembly 20. The body assembly 20 is suitable for being supported on the ground, and the head assembly 10 is arranged at the upper end of the body assembly 20 and can rotate relative to the body assembly 20. The head assembly 10 may include a head shell 300, a reflective cover 200 and a heating device 100. The heating device 100 is a heating pipe 100. The head shell 300 is connected to the body assembly 20. The reflective cover 200 is arranged in the head shell 300. The reflective cover 200 has a cover cavity 201, and the heating pipe 100 is arranged in the cover cavity 201. The heating pipe 100 can be a luminous heating body. The radiant heat of the heating pipe 100 during operation can be evenly irradiated to the area to be heated after being reflected by the wall of the cover cavity 201.

[0086] The head assembly 10 may include a head shell 300, a reflector 200 and a heating pipe 100. The head shell 300 has a hollow cavity 301 and a mounting cavity 302 surrounding the hollow cavity 301. The two ends of the hollow cavity 301 in the length direction are open. For example, the hollow cavity 301 is a cylindrical cavity, and the two ends of the hollow cavity 301 in the axial direction are open. This can not only improve the fashion sense of the heating device 1 and improve the user's sensory experience, but also the airflow can pass through the head assembly 10 through the hollow cavity 301, which is convenient for heat dissipation of the head assembly 10 and avoid the danger caused by the head assembly 10 being overheated.

[0087] The reflector 200 is disposed in the installation cavity 302, and the shape of the reflector 200 is adapted to the shape of the installation cavity 302. For example, if the installation cavity 302 is an annular cavity surrounding the hollow cavity 301, the middle of the reflector 200 has an escape opening for escaping the hollow cavity 301. The reflector 200 has a cavity 201, and the heating pipe 100 is disposed in the cavity 201. The head assembly 10 is rotatably disposed on the body assembly 20.

[0088] The head housing 300 may include a rear housing 320, a front housing 310 and a middle ring cylinder 330. The rear housing 320 has a circular first through hole 321, which is formed in the middle of the rear housing 320. The front housing 310 has a circular second through hole 311, which corresponds to the first through hole 321 in the front and back, and is formed in the middle of the front housing 310. The outer edge of the front housing 310 is detachably connected to the outer edge of the rear housing 320 by snapping. The middle ring tube 330 is arranged in the middle of the head housing 300 and between the rear shell 320 and the front shell 310. The rear end of the middle ring tube 330 is connected to the rear shell 320, and the front end of the middle ring tube 330 is connected to the front shell 310. The middle ring tube 330 is formed into a cylindrical structure. The middle part of the middle ring tube 330 defines a hollow cavity 301. The rear end of the hollow cavity 301 is connected to the first through hole 321, and the front end of the hollow cavity 301 is connected to the second through hole 311 to realize a flow passage connected to the external environment. The outer side wall of the middle ring tube 330, the rear side wall of the front shell 310, and the front side wall of the rear shell 320 jointly define the installation cavity 302. This facilitates the formation of the hollow cavity 301 and the installation cavity 302, facilitates the processing and setting of the head housing 300, and facilitates the assembly and molding of the head assembly 10.

[0089] The upper side wall of the middle ring tube 330 has a first ventilation hole 331 that penetrates along the thickness direction, and the first ventilation hole 331 is used to connect the hollow cavity 301 and the cover cavity 201. In this way, the air in the hollow cavity 301 can flow into the cover cavity 201 through the first ventilation hole 331 to dissipate heat to the structure in the cover cavity 201, reduce the problems in the cover cavity 201, avoid the over-high temperature in the cover cavity 201 and affect the service life of the head assembly 10, and also avoid the risk of burns caused by the user accidentally touching the head assembly 10. In other words, the first ventilation hole 331 can introduce new cold air to reduce the temperature of the whole machine. The upper side wall of the hollow cavity 301 is provided with a heat insulation rib 332 protruding toward the middle part of the hollow cavity 301, and the heat insulation rib 332 extends along the axial direction of the middle ring tube 330. In this way, the temperature here can be prevented from being too high, and the user will not be burned when using the hollow cavity 301 as a handle.

[0090] The front shell 310 may include an outer shell cover 312, a middle ring cover 313 and a protective net 314. The outer shell cover 312 is formed as a circular annular clamping member. The outer edge of the outer shell cover 312 is clamped and connected to the outer edge of the rear shell 320. The middle part of the outer shell cover 312 has a first avoidance hole 3121 with a large diameter. The middle ring cover 313 is a circular annular clamping member. The middle ring cover 313 is clamped and connected to the front end of the middle ring cylinder 330. The middle part of the middle ring cover 313 defines a second through hole 311. The protective net 314 is formed as an annular mesh structure. The outer edge of the protective net 314 is clamped between the reflector 200 and the outer shell cover 312. The inner edge of the protective net 314 is clamped between the middle ring cover 313 and the middle ring cylinder 330. The middle part of the protective net 314 protrudes toward the front and is exposed from the area between the first avoidance hole 3121 and the second through hole 311. This not only facilitates the processing and manufacturing of the front shell 310, but also further facilitates the assembly and molding of the head assembly 10.

[0091] The reflector 200 is formed into a flared cover body with a gradually increasing cross-sectional area from the back to the front. The front end of the reflector 200 is opened to form a circular air guide port 202. The first avoidance hole 3121 can be arranged concentrically with the air guide port 202, and the aperture of the first avoidance hole 3121 is larger than the aperture of the air guide port 202. Preferably, in the radial direction of the outer shell cover 312, the distance between the first avoidance hole 3121 and the air guide port 202 is greater than or equal to 7 mm. In this way, the first avoidance hole 3121 can avoid the air guide port 202, so that the radiant heat and hot air can be smoothly output from the air guide port 202. If the first avoidance hole 3121 is located on the inner side of the air guide port 202, an area that is not convenient for air flow will appear between the inner edge of the outer shell cover 312 and the reflector 200, where the temperature will rise sharply, and even damage to the structure such as the outer shell cover 312 will be caused.

[0092] The reflector 200 may include a cover body 210 and a mounting ring seat 220. The cover body 210 defines a cover cavity 201. The cover body 210 has a second avoidance hole 211 in the middle of the rear end. The mounting ring seat 220 is arranged in the cover cavity 201 and connected to the cover body 210 at the second avoidance hole 211. A bracket 222 is installed on the outer side of the mounting ring seat 220. The heat pipe 100 is formed as an annular tube. The heat pipe 100 is suitable for being sleeved on the outer side of the mounting ring seat 220 and fixed on the bracket 222. The bracket 222 is multiple and is arranged at intervals along the circumference of the mounting ring seat 220. In this way, the reflector 200 can reflect the radiant heat of the heat pipe 100, so that the heat can evenly heat the area to be heated.

[0093] The head assembly 10 may further include a temperature limiter 400, at least a portion of which is disposed in the housing cavity 201 and above the heating tube 100. It should be understood here that the temperature limiter 400 is a temperature-sensitive controller that makes the temperature lower or higher than a certain value under normal working conditions. For example, the temperature limiter 400 detects the temperature of the air in the reflector 200 under normal working conditions, makes the operating temperature in the reflector 200 lower than the first preset temperature value, and can promptly control the heating device 1 to stop working when the temperature in the reflector 200 rises abnormally.

[0094] The reflector 200 may have a mounting hole 203, the shape of which is adapted to the stopper, and a portion of the temperature limiter 400 may be disposed in the mounting cavity 302 and another portion may extend into the housing cavity 201 through the mounting hole 203. This facilitates the installation and connection of the temperature limiter 400, and facilitates the temperature limiter 400 to accurately detect the temperature in the housing cavity 201, thereby ensuring the detection effect of the temperature limiter 400.

[0095] The fuselage assembly 20 may include a base 21, a first column 22, and a second column 23, wherein the first column 22 is detachably connected to the base 21. The second column 23 is detachably connected to the first column 22, and the head assembly 10 is rotatably disposed on the second column 23, and a wire passage is defined between the first column 22 and the second column 23. This not only facilitates the disassembly and assembly of the fuselage assembly 20, and facilitates the transportation and carrying of the heating device 1, but also allows the wiring harness such as the power cord to be routed through the wire passage, and no threading is required during assembly, which not only facilitates the assembly operation, but also facilitates the simplification of the structure of the fuselage assembly 20.

[0096] The second column 23 includes a column body, a positioning push rod 231 and a spring 232. The fuselage assembly 20 also includes a positioning plate 24. The positioning plate 24 is detachably arranged on the column body. The positioning push rod 231, the spring 232 and the positioning plate 24 cooperate to realize the positioning of the head assembly 10 at different positions. Further, the positioning plate 24 includes a guide structure 241 for positioning and guiding the installation of the head assembly 10, which is convenient for the installation of the rear shell 320. The positioning plate 24 includes a limiting structure 242 and a positioning groove 243 for positioning the rotation position of the head assembly 10. The positioning push rod 231 can cooperate with the positioning groove 243. The positioning structure composed of the limiting structure 242, the positioning groove 243 and the positioning push rod 231 can be two independent positioning structures. Both positioning structures can be used to limit the rotation angle of the rear shell 320. The positioning plate 24 is also provided with a buckle structure 244, which can be snap-fitted with the second column 23. The first column 22 has a knob structure and a base fixing hole, which facilitates the installation and removal of the base 21 .
