Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a portable outdoor heater, including a table clamp assembly 1, a gas cylinder bracket 2 screwed to the bottom of the table clamp assembly 1, a gas cylinder 3 clamped to the inner wall of the gas cylinder bracket 2, a regulator coupling 4 at the top of the gas cylinder 3, a gas hose 5 on one side of the regulator coupling 4, a valve coupling 6 inserted at the other end of the gas hose 5, a burner 7 at the other end of the valve coupling 6, a combustion tube 8 inserted into one side of the inside of the burner 7, the combustion tube 8 vertically penetrating the inside of the tray assembly 9, and an igniter 10 on one side of the top of the tray assembly 9.

[0023] In this embodiment, as Figure 2 and Figure 5 As shown, the table clamp assembly 1 includes a watch clamp 101, an L-shaped bracket 102 is screwed to the top of the watch clamp 101, a thumb screw 103 is screwed to the middle of the bottom wall of the L-shaped bracket 102, and one side of the watch clamp 101 is screwed to one side of the gas cylinder bracket 2.

[0024] In this embodiment, as Figure 2 and Figure 5 As shown, one side of the gas cylinder bracket 2 is provided with two mounting screw plates 201. The upper mounting screw plate 201 is screwed with a gauge clip 101, and the lower mounting screw plate 201 is screwed with a bracket base 202.

[0025] In this embodiment, as Figure 4 As shown, an overflow safety valve 401 is provided on one side of the inner wall of the regulator coupling 4.

[0026] In this embodiment, as Figure 3 As shown, the burner 7 has a gas valve hole 701 located directly below the combustion tube 8 inside, and the gas valve hole 701 is vertically inserted into the combustion tube 8.

[0027] In this embodiment, as Figure 3 As shown, the tray assembly 9 includes a chassis 901, with a triangular spacer 902 on the inner wall of the chassis 901, a top plate 903 screwed to the top of the chassis 901, and the bottom of the chassis 901 screwed to the top opening of the burner 7.

[0028] In this embodiment, as Figure 3As shown, the igniter 10 includes an igniter cover 1001, which is screwed to one side of the top of the tray assembly 9. Thermocouples 1002 and igniter heads 1003 are respectively provided on both sides inside the igniter cover 1001.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the portable outdoor heater operates as follows:

[0030] First, the operator can connect the regulator coupling 4 of the gas regulator to the gas cylinder 3 and perform a leak test on all gas connections. Then, depending on the requirements, the gas cylinder bracket 2 can be placed directly on the workbench, or it can be connected to the gauge clip 101 and L-shaped bracket 102 of the table clamp assembly 1 using screws through the mounting plate 201 on one side. If it is installed on the edge of the workbench, the gauge clip 101 needs to be loosened by adjusting the thumb screw 103 of the table clamp assembly 1 according to the thickness of the table. The gas cylinder 3 can then be inserted into the gas cylinder bracket 2. The gas cylinder bracket 2 can then be pushed forward to press it against the edge of the table. Finally, the thumb screw 103 can be tightened to securely install the gas cylinder bracket 2 on the workbench. At the same time, the mounting plate 201 at the lower end of the gas cylinder bracket 2 can be connected to the bracket base 202 using screws to ensure that the gas cylinder bracket 2 is placed on a level and flat area and that the distance between the gas cylinder 3 and the equipment is at least 0.91 meters. During the operation, the gas cylinder 3 must always be kept upright.

[0031] Then, the operator can connect other components. Connect one end of the gas hose 5 to the regulator coupling 4 and the other end to the valve coupling 6. Connect the other end of the valve coupling 6 to the burner 7. During this process, ensure that the gas valve hole 701 is vertically inserted into the combustion tube 8. After completing the assembly of a series of components, the operator can confirm that the igniter 10 cable is connected and firmly screw the cable connector of the thermocouple 1002 into the thermocouple 1002 socket. At this time, the glass stone bag can be opened, and the glass stones can be evenly and neatly placed into the tray assembly 9 of the burner 7. Ensure that the igniter cover 1001 of the igniter 10 is not covered by the glass stones to prevent the glass stones from entering the igniter cover 1001. At the same time, keep it clean and dust-free to ensure smooth air circulation.

[0032] At this point, the operator can press and turn the burner 7 knob clockwise until its pointer stops, ensuring the equipment valve knob is in the closed position. Then, securely connect the regulator coupling 4 to the gas cylinder 3 and extend the hose to its full length. Perform a leak test on all connections again, using the gas cylinder support 2 for stability. After completing the above operations, the operator can push the knob inward to quickly turn it to the 12 o'clock position without releasing the gas knob. At this time, the igniter head 1003 will emit a spark and ignite the gas. The knob must be held down for 10 seconds during this process. Heating thermocouple 1002 will shut off the gas supply if it does not heat up sufficiently, causing the flame to extinguish. After 10 seconds, when thermocouple 1002 is fully heated, the knob can be released. The tabletop fire pit should remain lit. If it fails to ignite or the flame extinguishes after releasing the gas knob, turn the knob to the off position and wait at least five minutes for the gas to dissipate. Then, press and turn the knob to the high flame mode two or three times until burner 7 is lit. Once a visible flame is seen, keep the gas knob still for at least 10 seconds to complete the ignition.

[0033] After igniting the equipment, the operator can visually check whether the burner 7 is burning normally. The presence of the flame will confirm whether the burner 7 is working properly. During operation, the presence of the flame in the burner 7 should be checked periodically. If there is no flame, the equipment valve should be turned to the closed position immediately and the ignition procedure should be repeated. After use, the operator can turn the knob clockwise to switch the equipment valve to the closed position and allow the device to cool down for at least five minutes.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
