[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 5 As shown, the embodiment of the utility model provides a gas stove, which includes a main body, an air supply channel 20, a blasting part 30 and a gas nozzle 40. The main body has a housing cavity 11; the air supply channel 20 is arranged in the housing cavity 11, and the air supply channel 20 has an air inlet 201 and a mixed gas outlet 202 arranged oppositely, and the air supply channel 20 is also provided with a heat dissipation hole 203, which is respectively connected to the air supply channel 20 and the housing cavity 11, and the air inlet direction of the air inlet 201 and the side wall where the heat dissipation hole 203 is located have an angle, and the mixed gas is used to supply gas to the ejector 61 of the gas stove; the blasting part 30 is arranged in the housing cavity 11, and the blasting part 30 is connected to the air inlet 201; the gas nozzle 40 is arranged in the housing cavity 11, and the gas nozzle 40 has a gas outlet 403, and the gas outlet 403 is connected to the air supply channel 20, and the gas outlet 403 is located downstream of the heat dissipation hole 203.

[0034] The technical solution of the utility model can accelerate the circulation of air in the accommodating chamber 11, reduce the temperature in the accommodating chamber 11, and further reduce the temperature of the components in the accommodating chamber 11. Specifically, in the process of the blasting part 30 supplying air to the air supply channel 20, part of the air will flow into the accommodating chamber 11 through the heat dissipation holes 203, which not only improves the air flowability in the accommodating chamber 11, but also promotes the rapid dissipation of heat energy, thereby effectively reducing the temperature in the accommodating chamber 11, thereby reducing the heat load of the internal components, extending the service life of the gas stove, and improving the safety of use. Another part of the air is mixed with the gas flowing out of the gas nozzle 40 in the gas supply channel 20. In this solution, the position setting of the gas nozzle 40 avoids the possibility of gas flowing out through the heat dissipation holes 203, and at the same time, ensures that the air and gas are fully mixed before entering the ejector 61. Under the continuous action of the blasting part 30, the mixed gas is efficiently transported to the ejector 61 of the gas stove, providing an ideal gas ratio and flow rate for combustion, thereby improving the combustion efficiency and the overall performance of the gas stove. Figure 3 and Figure 5 The arrow direction is the gas flow direction.

[0035] like Figure 5As shown, further, the air supply channel 20 includes a heat dissipation channel 21 and a blast channel 22 which are independent of each other. The heat dissipation channel 21 has an open end and a blocked end which are arranged oppositely. The open end is connected to the air inlet 201; the two ends of the blast channel 22 are respectively connected to the air inlet 201 and the mixed gas outlet 202, and the gas outlet 403 is connected to the blast channel 22. The open end of the heat dissipation channel 21 is connected to the air inlet 201, ensuring the introduction of fresh air from the outside, and the introduced fresh air flows out into the accommodating cavity 11 through the heat dissipation hole 203. The design of the blast channel 22 makes the two ends respectively connected to the air inlet 201 and the mixed gas outlet 202, forming a directional airflow path. After the gas enters the blast channel 22 through the gas outlet 403, it mixes with the air from the heat dissipation channel 21 to form a mixed gas of a suitable proportion. This mixed gas is then transported to the ejector, providing uniform and efficient combustion conditions for the gas stove. The above scheme can avoid the possibility of gas entering the heat dissipation channel 21, ensuring the safe use of the gas stove.

[0036] like Figure 3 and Figure 5 As shown, specifically, the gas stove further includes a shell 70 and a baffle 50, and the shell 70 has the above-mentioned air supply channel 20. The air inlet 201 and the mixed gas outlet 202 are respectively arranged at two ends of the extension direction of the shell 70. The baffle 50 is arranged in the air supply channel 20, and the baffle 50 divides the air supply channel 20 into a blast channel 22 and a heat dissipation channel 21 that are independent of each other. In this way, the structure is simple, and it is easy to realize the assembly of the blast part 30 and the shell 70.

[0037] Specifically, in this solution, the blowing unit 30 includes a blower, and an air outlet of the blower is arranged in the air inlet 201 .

[0038] In order to reduce the resistance of air flowing in the heat dissipation channel 21, in this solution, the baffle 50 includes a curved plate 51, and the distance between the curved plate 51 and the side wall where the heat dissipation hole 203 is located gradually increases from the blocking end to the opening end of the curved plate 51. Specifically, the design of the curved plate 51 reduces friction and turbulence during air flow, thereby reducing resistance and improving air circulation efficiency in the heat dissipation channel 21.

[0039] Furthermore, the baffle 50 further includes a horizontal plate 52, which is connected to one end of the curved plate 51 close to the air inlet 201. The distance between the horizontal plate 52 and the side wall where the heat dissipation hole 203 is located is the same as the distance between one end of the curved plate 51 close to the air inlet 201.

[0040] Furthermore, a plurality of heat dissipation holes 203 are provided, and the plurality of heat dissipation holes 203 are spaced apart from each other along the direction from the opening end to the blocking end. The heat dissipation holes 203 are designed to be multiple, and this multi-hole design increases the air circulation area, thereby improving the efficiency of heat dissipation in the heat dissipation channel 21.

[0041] This solution does not limit the specific shape of the heat dissipation hole 203.

[0042] The heat dissipation holes 203 of this solution are long strip-shaped hole structures, and the heat dissipation holes 203 extend along the vertical direction from the open end to the blocked end. In addition, multiple heat dissipation holes 203 are distributed at intervals along the direction from the open end to the blocked end. This distribution method helps to form a uniform air flow, reduces the dead angle of air flow, and ensures that the heat in the heat dissipation channel 21 can be taken away more evenly and quickly.

[0043] In some other embodiments of the present solution, the heat dissipation hole 203 is a circular hole structure.

[0044] Furthermore, the blast channel 22 includes a first channel 221 and a second channel 222 which are connected in sequence, the flow area of ​​the second channel 222 is larger than the flow area of ​​the first channel 221, the air inlet 201 is connected to the first channel 221, the mixed gas outlet 202 is connected to the second channel 222, and the gas nozzle 40 is connected to the first channel 221. Since the gas nozzle 40 is connected to the first channel 221, the gas is initially mixed with the air here. Subsequently, the mixed gas enters the second channel 222 with a larger flow area for further mixing, and the flow area of ​​the second channel 222 is larger than the flow area of ​​the first channel 221. This gradient change design helps to reduce the flow velocity and increase the mixing time of air and gas in the process of the airflow flowing from the first channel 221 to the second channel 222, thereby improving the uniformity of mixing.

[0045] In order to improve the stability of combustion, an angle is formed between the outlet direction of the mixed gas outlet 202 and the extension direction of the first channel 221. Specifically, the outlet direction of the mixed gas outlet 202 is not directly aligned with the extension direction of the first channel 221, but is designed to form a specific angle. Due to the existence of the angle, the mixed gas flows out more smoothly, reducing the airflow disturbance that may be generated by direct impact, thereby improving the stability of combustion.

[0046] like Figure 5As shown, specifically, the gas nozzle 40 includes a gas inlet 401, a gas channel 402 and a gas outlet 403 which are connected in sequence, and the gas outlet 403 is located in the gas supply channel 20, and the gas outlet 403 is arranged away from the air inlet 201. The above arrangement can avoid the possibility of gas flowing to the heat dissipation channel 21, and ensure that the gas is mixed with the air in the blast channel 22; and the above arrangement also reduces the possibility of air flowing back from the air inlet 201 into the gas nozzle 40, and ensures the purity and pressure stability of the gas in the gas nozzle 40.

[0047] like Figure 1 As shown, further, the main body includes a base 10 and a cover plate that are interlocked, the accommodating cavity 11 is arranged on the base 10, and the through-hole is arranged on the cover plate. The through-hole is connected to the accommodating cavity 11, and the gas stove also includes an ejector 61 and a flame divider 62. The ejector 61 is arranged in the accommodating cavity 11, and the air inlet of the ejector 61 is connected to the mixed gas outlet 202; the flame divider 62 is located outside the accommodating cavity 11, and one end of the ejector 61 where the air outlet is located passes through the through-hole and is connected to the flame divider 62.

[0048] In the embodiment of the present scheme, the ejector 61 is further provided with an air inlet 611, which is provided at one end of the ejector 61 having an air inlet, and the air inlet 611 is communicated with the ejection channel inside the ejector 61. The air inlet 611 is provided at one end of the ejector 61 having an air inlet, and this layout facilitates air to directly enter the ejector 61, and to be mixed again with the mixed gas entering the ejector 61 from the mixed gas outlet 202, thereby further improving the mixing efficiency, optimizing the combustion performance, and improving the thermal efficiency.

[0049] Specifically, the ejector 61 includes a body and an end cover, wherein the body is provided with an ejection channel, and the end cover is provided at one end of the body away from the ignition distributor 62. The air inlet 611 and the air intake are provided on the end cover respectively. Two air inlets 611 are provided, and the two air inlets 611 are relatively provided on both sides of the air intake.

[0050] Furthermore, in this solution, a mixed gas nozzle 81 and a buffer portion 82 are also included. The mixed gas nozzle 81 is arranged between the housing 70 and the ejector 61, and the two ends of the mixed gas nozzle 81 are respectively connected to the ejection channel inside the ejector 61 and the mixed gas outlet 202. Through the arrangement of the mixed gas nozzle 81, after the mixed gas is output from the mixed gas outlet 202, it can be directly and efficiently input into the ejector 61, reducing the pressure loss and airflow disturbance during the transportation process.

[0051] In this solution, the gas stove further includes a buffer portion 82, one end of which is connected to the mixed gas nozzle 81, and the other end of which is connected to the ejector 61. The design of the buffer portion 82 helps to absorb and mitigate the vibration of the ejector 61 and the mixed gas nozzle 81 caused by the gas flow, thereby improving the stability of the gas stove system.
