[0038] Example

[0039] Please also read Figure 1 and Figure 2 This embodiment provides a gas heater, specifically a multi-angle rotating gas heater, which includes an air intake valve 100, a rotating connecting rod 200, a gas connector 300 and a combustion mechanism 400.

[0040] The rotating connecting rod 200 is vertically arranged and hollow inside, and the rotating connecting rod 200 is connected to the air intake valve 100. When the air intake valve 100 is opened, the combustible gas enters the inner cavity of the rotating connecting rod 200 through the air intake valve 100.

[0041] There are at least two gas connectors 300, each of which is connected to the rotating connecting rod 200, and at least one gas connector 300 is rotatably connected to the rotating connecting rod 200. When in use, the combustible gas entering the inner cavity of the rotating connecting rod 200 enters each gas connector 300 at the same time.

[0042] In addition, the combustion mechanism 400 is provided corresponding to the gas connector 300, the number of the two is the same, and the combustion mechanism 400 is fixedly connected to the corresponding gas connector 300. The combustible gas entering each gas connector 300 further enters the corresponding combustion mechanism 400, and burns and releases heat in the combustion mechanism 400.

[0043] In the above-mentioned gas heater, the air inlet valve 100 is connected to each gas joint 300 through a hollow rotating connecting rod 200, and the combustible gas is transported to the combustion mechanism 400 corresponding to each gas joint 300 for combustion and heat release. Since at least one gas joint 300 is rotatably connected to the rotating connecting rod 200, and the combustion mechanism 400 is fixedly connected to the corresponding gas joint 300, the user can rotate the gas joint 300 and the corresponding combustion mechanism 400 so that each combustion mechanism 400 faces different directions, achieving multi-angle heating and meeting the use needs in the heating scene of multiple people.

[0044] In some embodiments, there are at least three gas connectors 300. One of the gas connectors 300 is rotatably connected to one end of the rotating connecting rod 200, another gas connector 300 is rotatably connected to the other end of the rotating connecting rod 200, and the remaining gas connectors 300 are fixedly connected to the middle of the rotating connecting rod 200.

[0045] The rotatable gas connector 300 is arranged at both ends of the rotating connecting rod 200, which is more convenient for installation. At this time, the gas connector 300 and the corresponding combustion mechanism 400 are divided into three groups, which are respectively located at the two ends and the middle of the rotating connecting rod 200. The user can make the three groups of gas connectors 300 and the corresponding combustion mechanism 400 face the same direction, or make two groups of gas connectors 300 and the corresponding combustion mechanism 400 face the same direction, and make the other group of gas connectors 300 and the corresponding combustion mechanism 400 face another direction, or make the three groups of gas connectors 300 and the corresponding combustion mechanism 400 face different directions.

[0046] In some specific embodiments, there are three gas connectors 300 , two of which are respectively located at two ends of the rotating connecting rod 200 and are rotatably connected to the rotating connecting rod 200 , and the remaining gas connector 300 is fixedly connected to the middle of the rotating connecting rod 200 .

[0047] Please also read Figure 2 and Figure 3In some embodiments, the gas heater further includes a switch valve 500. The switch valve 500, the gas connector 300 and the combustion mechanism 400 are correspondingly arranged, and the number of the three is the same, and the combustion mechanism 400 is fixedly connected to the corresponding gas connector 300 through the switch valve 500.

[0048] By operating the switch valve 500, the user can individually control the opening and closing of each combustion mechanism 400, and select the number of combustion mechanisms 400 to be opened simultaneously according to actual needs, which is more energy-efficient.

[0049] Furthermore, the gas heater also includes an oxygen deficiency protection mechanism 600 (see Figure 6 The hypoxia protection mechanism 600 is provided corresponding to the switch valve 500 , the number of the two is the same, and the hypoxia protection mechanism 600 is connected to the corresponding switch valve 500 .

[0050] For example, when the oxygen in the air gradually decreases due to the combustion of the combustible gas, before the oxygen content drops to a level that affects normal human breathing, the flame will be separated from the heat sensing needle, and the heat sensing needle (i.e., the thermocouple) will stop generating current. In the absence of current, the solenoid valve automatically closes the switch valve 500, causing the combustion mechanism 400 to automatically cut off gas and stop combustion, so as to prevent the user from being poisoned by incomplete or unburned combustion of the combustible gas.

[0051] In some embodiments, the gas heater further comprises a housing 700 . The housing 700 , the gas connector 300 , the combustion mechanism 400 and the switch valve 500 are arranged correspondingly, and each housing 700 is stacked along the axis direction of the rotating connecting rod 200 .

[0052] Correspondingly, the gas connector 300 and the corresponding combustion mechanism 400 are accommodated in the corresponding housing 700 and fixedly connected to the corresponding housing 700 .

[0053] In some specific embodiments, the switch valve 500 is disposed on the housing 700 and is fixedly connected to the housing 700 , and the switch valve 500 has a knob 510 exposed outside the housing 700 .

[0054] In addition, a bracket 710 is fixedly disposed in the housing 700. The bracket 710 is rotatably sleeved on the rotating connecting rod 200, and the combustion mechanism 400 is fixedly connected to the bracket 710.

[0055] During use, the user rotates the housing 700 to drive the corresponding gas connector 300 , the combustion mechanism 400 , and the switch valve 500 to rotate, thereby adjusting the direction of the combustion mechanism 400 .

[0056] Please also read Figure 4 and Figure 5Furthermore, a limiting groove 720 is provided at the top of the shell 700, a limiting protrusion 730 is provided at the bottom of the shell 700, and the limiting protrusion 730 of the upper shell 700 is slidably provided in the limiting groove 720 of the lower shell 700.

[0057] When the user rotates the upper shell 700 relative to the lower shell 700, the limiting protrusion 730 of the upper shell 700 slides in the limiting groove 720 of the lower shell 700. The limiting groove 720 can limit the sliding range of the limiting protrusion 730, thereby limiting the relative rotation angle of the upper shell 700 and the lower shell 700.

[0058] In some specific embodiments, the limiting groove 720 is an arc-shaped groove, and the center of the limiting groove 720 coincides with the axis of the rotating connecting rod 200, and the center angle of the limiting groove 720 is not greater than 40°.

[0059] When in use, the shell 700 located at the top end of the rotating link 200 can rotate 40° relative to the rotating link 200, and the shell 700 located at the bottom end of the rotating link 200 can also rotate 40° relative to the rotating link 200. The shell 700 located in the middle of the rotating link 200 always remains relatively fixed with the rotating link 200.

[0060] Please refer again Figure 1 and Figure 2 In some specific implementation manners, the gas heater further includes a base 800 , and the outer shell 700 located at the bottom end of the rotating connecting rod 200 is fixedly connected to the base 800 .

[0061] It can be understood that during use, the housing 700 and the base 800 at the bottom of the rotating link 200 remain stationary, and the user can rotate the remaining housing 700 and the rotating link 200 to adjust the angle of the remaining housing 700. Subsequently, the user can continue to rotate the housing 700 at the top of the rotating link 200 to adjust the angle of the housing 700.

[0062] See also Figure 6 Specifically, the combustion mechanism 400 includes a nozzle assembly 410 and a burner assembly 420. One end of the nozzle assembly 410 is connected to the corresponding gas connector 300 through a switch valve 500, and the other end of the nozzle assembly 410 is connected to the burner assembly 420.

[0063] When the switch valve 500 is opened, the combustible gas enters the nozzle assembly 410 and is injected into the burner assembly 420 to burn and release heat.

[0064] In some specific implementations, the nozzle assembly 410 is composed of a nozzle holder and a nozzle.

[0065] Furthermore, the combustion mechanism 400 further includes a heat reflection cover 430 , and the heat reflection cover 430 is disposed on the heat generating end of the burner assembly 420 .

[0066] When in use, the heat generated by the combustion of the combustible gas is mainly transmitted in the form of heat radiation through the heating end of the burner assembly 420. The heat reflection cover 430 can reflect the electromagnetic waves propagating in all directions, so that the heat is concentrated and transmitted toward the front of the combustion mechanism 400, ensuring the heating effect.

[0067] In the above-mentioned gas heater, the air inlet valve 100 is connected to each gas joint 300 through a hollow rotating connecting rod 200, and the combustible gas is transported to the combustion mechanism 400 corresponding to each gas joint 300 for combustion and heat release. Since some gas joints 300 are rotatably connected to the rotating connecting rod 200, the user can rotate the gas joint 300 and the corresponding combustion mechanism 400 so that each combustion mechanism 400 faces different directions, realizing multi-angle heating and meeting the use needs in the heating scene of multiple people.

[0068] In short, the above-mentioned gas heater can achieve multi-angle rotation heating, meet the heating needs of multiple people, and has a simple structure.

[0069] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0070] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
