[0047] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0048] See Figures 1 to 7 This utility model discloses a portable heating device, comprising: a base 10; a heating structure 20, wherein the base 10 is provided with the heating structure 20, and the heating structure 20 includes a heating element 201; heating ports 101, wherein the base 10 is provided with at least three heating ports 101, each heating port 101 facing the heating element 201; and a heat reflection structure 30, wherein the heat reflection structure 30 is disposed outside the heating element 201, and the heat reflection structure 30 and the heating ports 101 are respectively disposed at different positions outside the heating element 201, and the heat reflection structure 30 faces the heating port 101.

[0049] The base 10 of this utility model is provided with at least three heating ports 101, each of which faces the heating element 201. The heat reflection structure 30 and the heating ports 101 are respectively arranged at different positions on the outside of the heating element 201. The heat reflection structure 30 assists in transferring the heat generated by the heating element 201 to the heating ports 101, so that users can warm themselves at at least three heating ports 101 positions of this utility model. This utility model has a large heat radiation range and is convenient for multiple people to use.

[0050] In this embodiment of the utility model, the portable heating device further includes a protective structure 40, which is disposed outside the heating element 201; the protective structure 40 includes at least three interconnected mesh protective parts 401, and the mesh protective parts 401 are arranged one-to-one with the heating port 101.

[0051] It should be noted that the mesh protective part 401 can not only protect the heating element 201 from being burned by the high temperature of the heating element 201, but also has a hollow part, which can also transfer heat to achieve heating.

[0052] The mesh protective part 401 can be made of metal, such as iron or aluminum. The protective structure 40 is disposed outside the heating element 201 to transfer the heat of the heating element 201 to the outside.

[0053] Since the mesh protective sections 401 are interconnected, it is convenient to install the protective structure 40 as a whole; thus, the heating ports 101 can also be interconnected, thereby achieving a larger range and a more concentrated annular heating.

[0054] In this embodiment of the utility model, the included angle between two adjacent mesh protective parts 401 is A, where 60°≤A≤150°.

[0055] See Figures 1 to 5 The included angle A between two adjacent mesh protective parts 401 is 90°, and the included angle A between two adjacent mesh protective parts 401 is 100°. Since 60°≤A≤150°, this utility model can achieve heating over a large range.

[0056] The number of heating vents 101 can be three, four, or five, depending on the actual situation and is not limited; the number of mesh protective parts 401 is determined by the number of heating vents 101.

[0057] The following example illustrates the situation with four heating outlets 101.

[0058] In this embodiment of the invention, the base 10 is provided with four heating ports 101, wherein the first heating port 101 faces the left side of the heating element 201, the second heating port 101 faces the right side of the heating element 201, the third heating port 101 faces the front side of the heating element 201, and the fourth heating port 101 faces the top of the heating element 201; the protective structure 40 includes four interconnected mesh protective parts 401, wherein the first mesh protective part 401 is located at the first heating port 101, and the second mesh protective part 401 is located at the second heating port 101. Position 01, wherein the third mesh protective part 401 is located at the third heating port 101, and the fourth mesh protective part 401 is located at the fourth heating port 101; the heat reflection structure 30 includes two interconnected mirror reflection parts 301, wherein the first mirror reflection part 301 is located at the rear side of the heating element 201, and the second mirror reflection part 301 is located at the bottom of the heating element 201; the protective structure 40 and the heat reflection structure 30 form a protective space, and the second mirror reflection part 301 is provided with a mounting hole 302 for facing the heating element 201.

[0059] It should be noted that the mirror reflector 301 is made of materials such as stainless steel or aluminum alloy.

[0060] Thus, the heating element 201 radiates heat to the left side of the base 10 through the first heating port 101, the heating element 201 radiates heat to the right side of the base 10 through the second heating port 101, the heating element 201 radiates heat to the front side of the base 10 through the third heating port 101, and the heating element 201 radiates heat to the top of the base 10 through the fourth heating port 101; and the first mirror reflector 301 reflects the heat from the heating element 201 to the position of the third heating port 101, and the second mirror reflector 301 reflects the heat from the heating element 201 to the position of the fourth heating port 101.

[0061] Thus, users can be heated when they are located on the left side, right side, or front side of the base 10; for some taller users, they can also be heated by using the heating vent 101 at the top of the base 10.

[0062] In this embodiment of the utility model, the heating element 201 is a burner, and the heating element 201 has a flame hole 202; the heating structure 20 also includes a gas pipe 203, which is connected to the heating element 201 to supply gas for combustion; the portable heating device also includes a flameout protection structure 50, which includes a thermocouple 501 and a solenoid valve 502. The thermocouple 501 is positioned close to the flame hole 202 of the heating element 201, and the thermocouple 501 and the solenoid valve 502 are electrically connected. The solenoid valve 502 is used to control the opening and closing of the gas pipe 203.

[0063] It should be noted that the flame hole 202 faces the mounting hole 302, so that the heat generated by the combustion of the heating element 201 can be transferred to the protective space through the mounting hole 302 and continue to be transferred outward through the protective structure 40.

[0064] It should be noted that the burner can be an existing burner. The burner also has an ignition structure. When the gas in the gas pipe 203 is sent to the burner, the burner switch is turned on, the ignition structure ignites, and combustion occurs at the burner's flame port 202. The heat from the combustion is transferred to the surroundings, such as to the protected space, to achieve heating.

[0065] It should be noted that thermocouple 501 can be a direct replacement for existing thermocouples, and solenoid valve 502 can be a direct replacement for existing solenoid valves.

[0066] When the heating element 201 is burning, the thermocouple 501 is heated by the flame, generating a thermoelectric potential. This thermoelectric potential is transmitted to the electromagnetic coil of the solenoid valve 502, which generates a magnetic field that causes the solenoid valve 502 to engage. This opens the gas passage of the gas pipe 203, allowing the gas pipe 203 to supply gas to the heating element 201, thus maintaining normal combustion. If the flame is extinguished by strong winds or other circumstances, the thermoelectric potential of the thermocouple 501 quickly drops to zero, the electromagnetic coil of the solenoid valve 502 is de-energized, the solenoid valve 502 resets, the gas passage of the gas pipe 203 closes, and the gas pipe 203 stops supplying gas to the heating element 201, thus forming a flameout protection, which improves the safety of this invention.

[0067] In this embodiment of the utility model, the flameout protection structure 50 also includes a tilt switch 503, which is disposed on the base 10. The tilt switch 503, the thermocouple 501, and the solenoid valve 502 are connected in series.

[0068] It should be noted that the tilt switch 503 can directly adopt an existing tilt switch. Its working principle is as follows: when the vertically suspended probe is subjected to an external force and deviates from the vertical position by a certain angle or more, such as more than 17 degrees, the metal ball contact inside the tilt switch 503 will activate and the normally closed contact will open; when the external force is removed, the probe returns to the vertical state and the metal ball contact will close again. Of course, other tilt switches 503 with different working principles can also be used, depending on the specific application environment, and there is no limitation.

[0069] Thus, when the base 10 tilts, the tilt switch 503 disconnects the electrical connection between the thermocouple 501 and the solenoid valve 502, thereby closing the gas passage of the gas pipe 203 and stopping the gas supply to the heating element 201, forming a flameout protection, which can improve the safety of this utility model.

[0070] In other words, when the heating element 201 is burning normally and the base 10 is not tilted, the gas passage of the gas pipe 203 is opened, and the gas pipe 203 supplies gas to the heating element 201, thereby maintaining the normal combustion of the heating element 201; if the heating element 201 goes out or the base 10 tilts, the gas pipe 203 will stop supplying gas to the heating element 201. The tilt switch 503, thermocouple 501 and solenoid valve 502 form a double flameout protection for the gas pipe 203, further improving the safety of this utility model.

[0071] In this embodiment of the present invention, the heating structure 20 further includes a first heat-conducting element 204, which is a mesh structure. The first heat-conducting element 204 covers the outside of the fire hole 202 of the heating element 201, and the heat reflection structure 30 is disposed outside the first heat-conducting element 204.

[0072] Specifically, the first heat-conducting element 204 can be made of metal, such as iron or aluminum.

[0073] Since the heating element 201 can burn with an open flame, the first heat-conducting element 204 can protect the flame hole 202 of the heating element 201 to prevent foreign objects from entering the flame hole 202 and causing malfunctions.

[0074] Furthermore, since the first heat-conducting element 204 has a mesh structure and a hollow portion, the first heat-conducting element 204 covers the outside of the fire hole 202 of the heating element 201 to transfer the heat of the heating element 201 outward; and the flame generated by the combustion of the heating element 201 shines on the heat reflection structure 30 through the hollow portion of the first heat-conducting element 204, and the heat reflection structure 30 reflects the flame to the heating port 101, thereby the heat reflection structure 30 assists in transferring the heat generated by the heating element 201 to the heating port 101.

[0075] In this embodiment of the utility model, the heating structure 20 further includes a gas storage component 205, the first end of the gas pipe 203 is connected to the heating element 201, and the second end of the gas pipe 203 is connected to the gas storage component 205; the heating element 201 and the gas storage component 205 are arranged side by side inside the base 10.

[0076] It should be noted that the gas storage component 205 can be a butane cartridge gas cylinder. The gas storage component 205 can be detachably connected to the gas pipe 203 or fixedly connected. When the gas storage component 205 is detachably connected to the gas pipe 203, the gas storage component 205 can be replaced.

[0077] A knob 2051 is provided on the gas pipe 203 or the gas storage device 205, and the gas supply flow rate of the gas pipe 203 is adjusted by using the knob 2051.

[0078] Since the heating element 201 and the gas storage element 205 are arranged side by side inside the base 10, the internal space of the base 10 can be reasonably arranged, making the overall structure of the portable heating device more compact.

[0079] In this embodiment of the present invention, the heating structure 20 further includes a second heat-conducting element 206, which is a sheet-like structure and includes a first connecting segment 2061, a second connecting segment 2062, and a third connecting segment 2063 connected to each other. The first connecting segment 2061 extends along the outer wall of the heating element 201 and is close to or abuts against the outer wall of the heating element 201. The third connecting segment 2063 extends along the outer wall of the gas storage element 205 and is close to or abuts against the outer wall of the gas storage element 205.

[0080] It should be noted that the second heat-conducting element 206 can be made of metal, such as iron or aluminum. The second heat-conducting element 206 can transfer the heat from the heating element 201 to the gas storage element 205. In particular, when the temperature is low in winter, the second heat-conducting element 206 can prevent the gas storage element 205 from freezing due to excessively low temperature, which would reduce the vaporization rate and thus affect the use of the portable heating device.

[0081] In this embodiment of the utility model, the portable heating device further includes a shelf 60, with the shelf disposed on the base 10 and the shelf disposed near the heating port 101; and / or, the base 10 is provided with a handle 70.

[0082] For example, the shelf 60 can be a tea tray, on which a Kung Fu tea cup can be placed to keep it warm, making it convenient for the user.

[0083] It should be noted that the handle 70 makes it easy for users to carry this portable heating device.

[0084] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
