[0038] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] See also Figure 1-6The utility model provides an angle-adjustable portable gas heater, comprising a gas bottle 1, a fixed shell 2 arranged on the gas bottle 1, a heater body with a shell 3, and a sliding assembly 4 arranged between the shell 3 and the fixed shell 2; wherein the sliding assembly 4 comprises a sliding plate 401 and a fixed plate 402, the sliding plate 401 is provided with a slide groove 4011, the fixed plate 402 is provided with a shaft body 403 penetrating the slide groove 4011; the sliding plate 401 and the fixed plate 402 are relatively slidable by the sliding cooperation between the slide groove 4011 and the shaft body 403; specifically, the sliding plate 401 is installed in the shell 3, and the fixed plate 402 is installed on the fixed shell 2. Therefore, when the user pushes the shell 3, the shell 3 can be rotated relative to the fixed shell 2 by the sliding of the sliding plate 401 relative to the fixed plate 402, thereby realizing the angle adjustment of the heater body.

[0042] In this embodiment, a mounting hole 4022 is defined on the fixing plate 402 , and the shaft 403 passes through the mounting hole 4022 .

[0043] It should be noted that in other embodiments, the setting positions of the sliding plate 401 and the fixed plate 402 can also be swapped. When the user pushes the fixed shell 2, it can also make the outer shell 3 rotate relative to the fixed shell 2, thereby achieving the angle adjustment of the heater body, which is not limited here.

[0044] Among them, since the volume of the heater body is large and the weight is heavy, it is also necessary to position and fix the rotation position of the heater body. Therefore, the present application also sets a positioning clamping structure between the sliding plate 401 and the fixed plate 402, wherein the positioning clamping structure includes a plurality of positioning holes 4012 provided on the sliding plate 401 and a positioning protrusion 4021 provided on the fixed plate 402, and the plurality of positioning holes 4012 are arranged at intervals along the extension direction of the slide groove 4011. Thus, when the user pushes the shell 3 to rotate until the positioning hole 4012 is engaged with the positioning protrusion 4021, the heater body can be fixed by clamping at this time; when the angle needs to be adjusted, the user only needs to push the shell 3 again to rotate to disengage the positioning hole 4012 from the positioning protrusion 4021, until the next positioning hole 4012 is engaged with the positioning protrusion 4021, the heater body can be positioned and fixed again.

[0045] Likewise, it should be noted that in other embodiments, the positions of the positioning holes 4012 and the positioning protrusions 4021 may be swapped, which can also achieve the same technical effect, and is not limited here.

[0046] Therefore, the portable gas heater of the utility model, by setting a sliding assembly 4 between the outer shell 3 of the heater body and the fixed shell 2, allows the heater body to rotate relative to the fixed shell 2, thereby realizing the angle adjustment of the heater body. Users can adjust the radiation angle according to their own needs, which has a wider range of usage scenarios and higher practicality.

[0047] In this embodiment, a base 13 is further included, and the gas cylinder 1 is placed on the base 13 .

[0048] See also Figure 2-6 The gas heater also includes a pressure reducing valve 8 connected to the fixed shell 2, and the air inlet end of the pressure reducing valve 8 is connected to the air outlet end of the gas bottle 1; in addition, the heater body also includes a burner 5 and a gas supply assembly 6 installed in the outer shell 3, and the gas bottle 1 is connected to the burner 5 through the gas supply assembly 6; specifically, the gas supply assembly 6 includes a gas regulating valve 601 with a knob 602, a first connecting pipe (not shown in the figure) and a second connecting pipe 603, and an air inlet 6011 and a main air outlet 6012 are provided on the gas regulating valve 601, the air outlet end of the pressure reducing valve 8 is connected to the air inlet 6011 through the first connecting pipe, and the main air outlet 6012 is connected to the burner 5 through the second connecting pipe 603.

[0049] Thus, the gas in the gas cylinder 1 can enter the gas regulating valve 601 through the pressure reducing valve 8 and the first connecting pipe, and enter the burner 5 through the second connecting pipe 603 for combustion.

[0050] Preferably, the first connecting tube is a wire-wrapped hose; thus, the use of the wire-wrapped hose can make the heater body more free and comfortable during the angle adjustment process, thereby ensuring the reliability of the gas circuit connection.

[0051] See also Figure 6 The portable heater also includes a safety protection device 7 arranged in the shell 3 and close to the burner 5. The safety protection device 7 includes a fixed bracket 706 and a thermocouple 701, a long-fire assembly and an ignition needle 702 arranged on the fixed bracket 706. The long-fire assembly includes an air inlet connector 703, a gas mixing pipe 704 and a mother fire nozzle 705. The ignition needle 702 and the thermocouple 701 are both arranged close to the outlet of the mother fire nozzle 705; in addition, the gas supply assembly 6 also includes a third connecting pipe 604, and the gas regulating valve 601 also includes a long-fire outlet 6013, and the long-fire outlet 6013 is connected to the air inlet connector 703 through the third connecting pipe 604; the gas regulating valve 601 is also provided with a valve body (not shown in the figure) connected to the air inlet 6011, and the thermocouple 701 controls the movement of the valve body through a thermocouple connecting line (not shown in the figure) to open or close the air inlet 6011.

[0052] Thus, when the knob 602 is pressed to drive the valve body to move and open the air inlet 6011, the gas in the gas bottle 1 can enter the gas regulating valve 601 through the pressure reducing valve 8 and the first connecting pipe, and then be discharged from the pilot flame outlet 6013 and enter the pilot flame assembly, and then the gas is discharged from the mother flame nozzle 705, and the ignition needle 702 ignites the gas. The heat generated after the ignition causes the thermocouple 701 to generate current, and the potential generated at one end of the thermocouple connecting line close to the valve body to attract the valve body. At this time, the air inlet 6011 is always in an open state, and the gas can be discharged from the main outlet 6012 of the gas regulating valve 601 and enter the burner 5 through the third connecting pipe 604 to burn. During the combustion process, the user can adjust the gas intake by turning the knob 602 to adjust the firepower.

[0053] In the specific use process, in order to prevent the gas heater from tipping over or suddenly causing harm to the user, the present application also provides a tipping switch 9 and a closing button 14. The tipping switch 9 is arranged inside the housing 3, and the closing button 14 is arranged on the housing 3. The tipping switch 9 and the closing button 14 are both electrically connected to the thermocouple connecting wire. Therefore, once the gas heater tips over, the tipping switch 9 can remove the potential on the thermocouple connecting wire, thereby resetting the valve body and closing the air inlet 6011, thereby realizing the cutting off of the gas path; similarly, when an accident occurs, the user can press the closing button 14 to remove the potential on the thermocouple connecting wire, thereby resetting the valve body and cutting off the gas path, thereby ensuring the safety and reliability of the product during use.

[0054] Furthermore, it also includes a gas distribution rod 605 and a combustion tube 606 arranged between the burner 5 and the second connecting tube 603, one end of the combustion tube 606 is connected to the burner 5, and the other end is connected to the gas distribution rod 605, and the gas distribution rod 605 is connected to the second connecting tube 603. Therefore, by setting the gas distribution rod 605, the gas is evenly and reasonably distributed, and the gas is mixed with the air more evenly, thereby improving the combustion efficiency.

[0055] In addition, the gas heater further includes a heat shield 11 and a protective net 12. The heat shield 11 is arranged on the periphery of the burner 5, and the protective net 12 is installed on the heat shield 11 and is located at the front end of the burner 5. Therefore, by providing the protective net 12 and the heat shield 11, it is possible to prevent the user from accidentally touching the burner and causing injury, thereby improving the safety of product use.

[0056] In addition, the gas heater further comprises a decorative ring 10, which is sleeved on the outer peripheral side of the heat shield 11, thereby making the overall appearance of the product more concise and beautiful, and making it more upscale.

[0057] To sum up, the utility model provides a portable gas heater with adjustable angle. By setting a sliding component 4 between the outer shell 3 of the heater body and the fixed shell 2, the heater body can be rotated relative to the fixed shell 2, thereby realizing the angle adjustment of the heater body. Users can adjust the radiation angle according to their own needs. The usage scenarios are more extensive and the practicality is higher.
