[0040] Reference Figures 1 to 3 According to an embodiment of the present invention, a barbecue grill includes a shell assembly 100, a combustion assembly, an ignition assembly 200 and a regulating valve 300. The shell assembly 100 is provided with a combustion chamber 110 and a receiving chamber 120 spaced apart from the combustion chamber 110. The combustion assembly is provided in the combustion chamber 110. The ignition assembly 200 is provided in the combustion chamber 110. The ignition assembly 200 is used to ignite the combustion assembly. The regulating valve 300 is provided in the receiving chamber 120. The regulating valve 300 includes a valve body 310 and a regulating assembly 320. The valve body 310 has an air inlet channel 311, a first air outlet 312 and a second air outlet 313. The air inlet channel 311 is connected to the first air outlet 312 and the second air outlet 313 respectively. The first air outlet 312 is used to transport gas to the combustion assembly, and the second air outlet 313 is used to transport gas to The ignition component 200 and the air inlet channel 311 are used to install the gas bottle 900. The adjustment component 320 is rotatably provided on the air inlet channel 311 so that the adjustment valve 300 has an open state and a closed state. When the adjustment valve 300 is in the closed state, the first air outlet 312 and the second air outlet 313 are both closed. When the adjustment valve 300 switches from the closed state to the open state, the second air outlet 313 opens first and the first air outlet 312 opens later. In this way, when the user opens the adjustment valve 300, the gas can be first delivered to the ignition component 200 to generate an open flame, and then the gas is delivered to the combustion component. The open flame can directly ignite the gas delivered to the combustion component to avoid explosion, which can prevent the user from being burned, thereby improving the safety of the barbecue grill.

[0041] Specifically, when the user uses the barbecue grill to cook food, the user can rotate the adjustment component 320 to connect the second through hole 323 with the air intake channel 311, and the gas in the air intake channel 311 can be transported to the ignition component 200 through the second through hole 323 to be ignited to produce an open flame, and then continue to rotate the adjustment component 320 to connect the first through hole 322 with the air intake channel 311, and the gas in the air intake channel 311 can be transported to the combustion component through the first through hole 322 to be directly ignited by the open flame of the ignition component 200, which can avoid the occurrence of explosions and prevent users from being burned, thereby improving the safety of the barbecue grill.

[0042] It should be noted that the shell assembly 100 includes a first shell 101 and a second shell 102 , the combustion chamber 110 is provided in the first shell 101 , and the accommodating chamber 120 is provided in the second shell 102 , which is not limited here.

[0043] Reference Figures 4 to 9 In some embodiments of the present invention, the adjustment component 320 is provided with an avoidance groove 321, and the side wall of the avoidance groove 321 is provided with a first through hole 322 and a second through hole 323. When the adjustment valve 300 is in the open state, the first air outlet 312 is connected to the first through hole 322, and the second air outlet 313 is connected to the second through hole 323. The first through hole 322 and the second through hole 323 are arranged at intervals along the axial direction of the adjustment component 320 and at intervals along the circumferential direction of the avoidance groove 321, so that the adjustment valve 300 can first open the second air outlet 313 and then open the first air outlet 312, so as to improve the safety of the barbecue grill.

[0044] Specifically, the first air outlet 312 and the second air outlet 313 are arranged at axial intervals along the air inlet channel 311. When the regulating valve 300 is switched from a closed state to an open state, when the regulating component 320 is rotated to a certain angle, the second air outlet 313 is first connected with the second through hole 323, so that the gas can be delivered to the ignition component 200 and generate an open flame. When the regulating component 320 is continued to be rotated, the first air outlet 312 is connected with the first through hole 322, so that the gas is delivered to the combustion component and ignited by the open flame at the ignition component 200. This can avoid the occurrence of excessive gas in the combustion chamber 110 of the combustion component, thereby avoiding explosion in the combustion chamber 110, and can improve the safety of the barbecue grill.

[0045] Reference Figure 9 In some embodiments of the present invention, the diameter of the first through hole 322 is larger than the diameter of the second through hole 323, which can reduce the waste of gas, thereby reducing the use cost of the barbecue grill and improving the market competitiveness of the barbecue grill.

[0046] Reference Figures 5 to 9In some embodiments of the present application, the outer circumferential side of the adjusting assembly 320 is provided with a groove 324 which penetrates the side wall of the second through hole 323 along the axial direction of the adjusting assembly 320, the projection of the first through hole 322 overlaps the projection of the groove 324, so that the second gas outlet hole 313 can still emit gas when the first gas outlet hole 312 emits gas, which can ensure that the ignition assembly 200 can continuously generate a bright fire when the gas is delivered to the combustion assembly, so that the gas at the combustion assembly can be ignited by the bright fire in time to avoid the occurrence of deflagration in the combustion chamber 110, and the use safety of the barbecue oven can be improved.

[0047] Specifically, the groove 324 is in an arc shape, the groove opening of the groove 324 penetrates the outer circumferential side of the adjusting assembly 320, and the side wall of the groove 324 penetrates the side wall of the second through hole 323. When the first through hole 322 communicates with the first gas outlet hole 312, the groove 324 can communicate with the second gas outlet hole 313, so that the gas in the gas inlet channel 311 can be delivered from the first through hole 322 to the groove 324 and then to the first gas outlet hole 312, so that the second gas outlet hole 313 can still emit gas when the first gas outlet hole 312 emits gas, which can ensure that the ignition assembly 200 can continuously generate a bright fire when the gas is delivered to the combustion assembly, so that the gas at the combustion assembly can be ignited by the bright fire in time to avoid the occurrence of deflagration in the combustion chamber 110, and the use safety of the barbecue oven can be improved.

[0048] Referring to Figure 2 , Figure 3 In some embodiments of the present application, the barbecue oven further comprises a heat dissipation fan 400 which is accommodated in the accommodating cavity 120, the side wall of the accommodating cavity 120 is provided with an air inlet hole 121 and an air outlet hole 122, the air inlet hole 121 and the air outlet hole 122 form a heat dissipation channel, and the heat dissipation fan 400 is arranged on the heat dissipation channel, so that the heat dissipation fan 400 can dissipate heat from the accommodating cavity 120 and make the air in the accommodating cavity 120 flow, which can ensure that the gas cylinder 900 works at a suitable ambient temperature.

[0049] Specifically, when a user cooks food using the barbecue oven, the heat in the combustion chamber 110 can be radiated to the accommodating cavity 120 to increase the temperature in the accommodating cavity 120. When the temperature in the accommodating cavity 120 is too high, the heat dissipation fan 400 can discharge the air with a too high temperature in the accommodating cavity 120 from the air outlet hole 122 and suck in the air with a lower temperature from the outside environment, which can ensure that the gas cylinder 900 works at a suitable ambient temperature.

[0050] It should be noted that it is well known that the gas cylinder 900 is prone to explosion when it works in a high-temperature environment, which can easily cause injury to the user. By arranging the heat dissipation fan 400, the temperature of the gas cylinder 900 can be effectively reduced, and the use safety of the barbecue oven can be improved.

[0051] Reference Figure 2 、 Figure 3 In some embodiments of the present invention, a control system and a temperature detection component 910 are further included. The temperature detection component 910 is accommodated in the accommodating cavity 120 and is electrically connected to the cooling fan 400 through the control system. A temperature detection component 910 electrically connected to the cooling fan 400 is provided in the accommodating cavity 120. The detection end of the temperature detection component 910 is close to the gas cylinder 900 to detect the actual temperature of the gas cylinder 900. When the operating temperature of the gas cylinder 900 is too high, the temperature detection component 910 can send an electrical signal to the control system to control the operation of the cooling fan 400 without starting the cooling fan 400 from the beginning of using the barbecue grill. This can reduce the electricity waste of the cooling fan 400 and reduce the cost of using the barbecue grill.

[0052] It should be noted that the electrical signal may be a low-level signal or a high-level signal, and the control system may be a CPU or a single-chip microcomputer, etc., which are not limited here.

[0053] It should be noted that gas cylinder 900 contains gas. During grilling, the gas in cylinder 900 must first be converted into vaporized gas before use. During grilling, the gas in cylinder 900 absorbs heat as it vaporizes, causing the cylinder 900 to gradually cool down. However, when the temperature of cylinder 900 is too low, the vaporization rate of the gas within it decreases. If the temperature of cylinder 900 is below 5°C, the gas may not even vaporize, which undoubtedly affects the barbecue's heat output. Therefore, the provision of accommodating chamber 120 allows some heat within combustion chamber 110 to be radiated into the accommodating chamber, raising the ambient temperature within accommodating chamber 120. This ensures that the gas in cylinder 900 can vaporize, ensuring that the barbecue's heat output meets the user's cooking needs. When the ambient temperature within accommodating chamber 120 falls below 5°C, temperature detection assembly 910, through the control system, controls cooling fan 400 to stop operating, raising the ambient temperature within accommodating chamber 120 and ensuring the barbecue's heat output.

[0054] Reference Figure 3 In some embodiments of the present invention, the ignition assembly 200 includes a seat body 210, an ignition needle 220 and a first nozzle 230. The seat body 210 is connected to the shell assembly 100. The ignition needle 220 and the first nozzle 230 are both provided on the seat body 210 and are both accommodated in the combustion chamber 110. The ignition needle 220 is used for ignition. The first nozzle 230 is connected to the second air outlet 313 to spray out gas. The ignition needle 220 and the first nozzle 230 are arranged opposite to each other, which can facilitate the ignition assembly 200 to generate open flames.

[0055] Specifically, the nozzle end of the first nozzle 230 is facing the ignition end of the ignition needle 220, and the first nozzle 230 is connected to the second air outlet 313 through the first connecting pipe 240, so that the gas in the second air outlet 313 can flow to the first nozzle 230 and be sprayed to the ignition end of the ignition needle 220, which can facilitate the ignition component 200 to generate an open flame.

[0056] It should be noted that the base 210 is mounted on the housing assembly 100 by means of bolts or screws, which is not limited here.

[0057] In some embodiments of the present invention, the combustion assembly (not shown in the figure) includes an infrared ceramic sheet (not shown in the figure) and a second nozzle (not shown in the figure). The second nozzle is connected to the first air outlet 312 through a second connecting pipe so that the gas from the first air outlet 312 can flow to the second nozzle and be sprayed to the infrared ceramic sheet, which can facilitate baking food.

[0058] Reference Figures 10 to 12 In some embodiments of the present invention, a safety mechanism is further included, which includes a blocking member 500, an adjusting member 600, a limiting member 700 and a pushing member 800. The blocking member 500 is movably arranged in the accommodating cavity 120 to have a first state close to the air inlet channel 311 and a second state away from the air inlet channel 311. When the blocking member 500 is in the second state, the blocking member 500 can interfere with the gas bottle 900 so that the gas bottle 900 cannot be installed in the air inlet channel 311. The adjusting member 600 is rotatably connected to the housing assembly 100. A transmission structure is provided between the adjusting member 600 and the blocking member 500. When the adjusting member 600 rotates, the transmission structure can drive the blocking member 500 to switch between the first state and the second state. The limiting member 700 is rotatable. It is movably arranged on the shell assembly 100, and the pushing member 800 is arranged on the adjustment assembly 320. The end of the pushing member 800 away from the adjustment end is used to push the limit member 700 to rotate. When the regulating valve 300 is switched to the open state, the pushing member 800 can push the limit member 700 to abut against the adjusting member 600 in the second state. In this way, when the blocking member 500 is in the second state, if the regulating valve 300 is in the open state, the limit member 700 will abut against the adjusting member 600 to limit the rotation of the adjusting member 600, so that the adjusting member 600 cannot adjust the blocking member 500 to switch to the first state, that is, the gas cylinder 900 cannot be connected to the air inlet channel 311, so as to avoid gas leakage in the gas cylinder 900, which can improve the safety of the gas stove.

[0059] Specifically, when installing the gas cylinder 900, the user needs to first rotate the adjustment component 320 to make the regulating valve 300 in the closed state. At this time, the user can rotate the adjustment member 600, and the adjustment member 600 drives the blocking member 500 to switch to the first state through the transmission structure, so that the gas cylinder 900 can be connected to the air inlet channel 311. If the user does not rotate the adjustment component 320 to drive the regulating valve 300 to switch to the closed state, that is, the regulating valve 300 is still in the open state, at this time, the pushing member 800 can abut against the adjustment member 600 to limit the rotation of the adjustment member 600, so that the adjustment member 600 cannot drive the blocking member 500 to move through the transmission structure, so that the blocking member 500 switches to the first state, which can avoid the occurrence of gas leakage in the gas cylinder 900 and improve the safety of the gas stove.

[0060] It should be noted that, referring to the figure, when the regulating valve 300 is in the closed state, the air inlet channel 311 is not connected to the first air outlet 312 and the second air outlet 313. The user can drive the regulating valve 300 to switch between the closed state and the open state by rotating the regulating component 320 to drive the regulating end to rotate.

[0061] It should be noted that the rotation plane of the adjusting member 600 intersects with the rotation plane of the adjusting assembly 320 so that the pushing member 800 can abut against the adjusting member 600 , which is not limited here.

[0062] It should be noted that the rotation plane of the adjusting member 600 is orthogonal to the rotation plane of the adjusting assembly 320 so that the pushing member 800 can abut against the adjusting member 600 , which is not limited here.

[0063] It can be understood that the rotation plane of the adjusting member 600 is defined as the plane formed by the rotation trajectory of the adjusting member 600 when the adjusting member 600 rotates, and the rotation plane of the adjusting member 600 is perpendicular to the axial direction of the end where the adjusting member 600 is connected to the shell assembly 100. The rotation plane of the adjusting component 320 is defined as the plane formed by the rotation trajectory of the adjusting component 320 when the adjusting component 320 rotates, and the rotation plane of the adjusting component 320 is perpendicular to the axial direction of the adjusting end, which will not be described in detail here.

[0064] It is understandable that when the user needs to replace the gas cylinder 900 that has run out of gas, the user can turn the adjustment member 600 to drive the blocking member 500 to switch to the second state through the transmission structure, so that the gas cylinder 900 can be moved in a direction away from the air inlet channel 311 to disconnect the connection between the gas cylinder 900 and the air inlet channel 311. The operation is simple, convenient and fast. There is no need to manually pull out the gas cylinder 900, which can facilitate the user to replace the gas cylinder 900.

[0065] Reference Figure 14It should be noted that the blocking member 500 is provided with a mounting groove 520, and the mounting groove 520 is used to install the gas cylinder 900, so as to facilitate the installation of the gas cylinder 900.

[0066] Reference Figure 16 It should be noted that the limit member 700 is provided with an avoidance channel 710, and the side wall of the avoidance channel 710 is provided with a notch 711. When the regulating valve 300 is in the closed state, the regulating member 600 can enter the avoidance channel 710 through the notch 711 to avoid interference between the blocking member 500 and the gas cylinder 900, which will not be described in detail here.

[0067] In some embodiments of the present invention, a side wall of the accommodating cavity 120 is provided with a avoidance opening, and the air inlet channel 311 faces the avoidance opening. The avoidance hole is used for the gas cylinder 900 to pass through, which can facilitate the installation and removal of the gas cylinder 900, so that the user can replace the gas cylinder 900.

[0068] Reference Figure 13 、 Figure 14 In some embodiments of the present invention, the transmission structure includes a transmission shaft 510 provided on the blocking member 500 and a waist-shaped hole 610 provided on the adjusting member 600. The transmission shaft 510 is passed through the waist-shaped hole 610 and can abut against the side wall of the waist-shaped hole 610, so that the user can switch the blocking member 500 between the first state and the second state by toggling the adjusting member 600. The operation is simple, convenient and fast, so as to facilitate the installation and removal of the gas cylinder 900.

[0069] Specifically, refer to Figure 13 、 Figure 14 00 and the shell assembly 100. When the locking member 500 is in the first state, the side wall of the waist-shaped hole 610 away from the end where the adjusting member 600 and the shell assembly 100 are hinged abuts against the transmission shaft 510 to push the blocking member 500 to move in the direction close to the end where the adjusting member 600 and the shell assembly 100 are hinged. When the locking member 500 is switched from the second state to the first state, the side wall of the waist-shaped hole 610 close to the end where the adjusting member 600 and the shell assembly 100 are hinged abuts against the transmission shaft 510 to push the blocking member 500 to move in the direction away from the end where the adjusting member 600 and the shell assembly 100 are hinged. The operation is simple, convenient and fast, so as to facilitate the installation and removal of the gas cylinder 900.

[0070] It should be noted that the transmission structure can also be a rack and pinion transmission structure, which includes a rack provided on the blocking member 500 and a gear rotatably provided on the shell assembly 100. The gear is engaged with the rack, and the user can drive the blocking member 500 to switch between the first state and the second state by rotating the gear.
