[0002] A gas stove is a kitchen appliance required for cooking in daily family life. The gas stove includes a burner, and the burner cap assembly of the burner usually includes a burner cap base and an outer ring burner cap. The outer ring burner cap is buckled on the burner cap base to form an outer ring mixing cavity, and a plurality of main fire holes communicating with the outer ring mixing cavity are formed on the circumferential side wall of the outer ring burner cap. The flame generated by the burner is mainly distributed at the main fire holes of the outer ring burner cap. Therefore, the temperature of the outer ring burner cap is the highest, which can reach 300°C to 500°C. Since the outer ring burner cap is arranged on the burner cap base, the contact area is relatively large, and the heat of the outer ring burner cap will be conducted to the burner cap base, so that the temperature of the burner cap base will also reach this temperature. The burner cap base made of ordinary aluminum material is easy to melt or deform when used at this high temperature for a long time.
[0003] At present in the market, the gas stove often uses high-temperature resistant aluminum material to make the burner cap base to solve the problem that the burner cap base is easy to melt or deform when used at a high temperature for a long time. However, this will undoubtedly increase the production cost of the product.

[0012] As an alternative solution, along the circumferential direction of the outer ring burner cap, the heat dissipation grooves are located on the side of the main fire holes, and the heat dissipation grooves and the main fire holes are alternately arranged in sequence.
[0013] As an alternative solution, along the axial direction of the outer ring burner cap, one end of the heat dissipation groove is close to the upper edge of the outer ring burner cap, and the other end of the heat dissipation groove extends to the contact surface between the outer ring burner cap and the burner cap seat.

[0022] The beneficial effects of the present utility model:
[0023] The utility model provides a burner head assembly. By arranging heat dissipation grooves beside the main fire holes, the heat dissipation area is increased. When gas jets outwards through the main fire holes, the gas flow velocity at the main fire holes is high, so the pressure is low, which will drive the cold air below to flow upwards. When the external cold air passes through the heat dissipation grooves, the cold air will take away a part of the heat of the outer ring burner head and turn into hot air, and discharge from above the heat dissipation grooves, realizing the heat exchange with the cold air, thereby reducing the temperature of the part of the outer ring burner head provided with the heat dissipation grooves. And because this part of the outer ring burner head is also in contact with the burner head base, the heat of the burner head base will be conducted to the outer ring burner head, further reducing the temperature of the burner head base, solving the problem that the burner head base is prone to melting or deformation when used under high temperature for a long time, and not increasing the production cost of the product. Secondly, by arranging the heat dissipation grooves, it can also promote the air to enter the flame through the heat dissipation grooves, promote the full combustion of the gas, and achieve the effect of enhancing the flame.

By arranging the above-mentioned burner, the temperature of the burner head base can be reduced, solving the problem that the burner head base is prone to melting or deformation when used under high temperature for a long time, and not increasing the production cost of the product.

Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] This embodiment provides a burner cap assembly, which is applied to a burner. As Figure 1 and Figure 2 shown, the burner cap assembly includes a burner cap seat 10 and an outer ring burner cap 20. The outer ring burner cap 20 is covered on the burner cap seat 10 and forms an outer ring gas mixing cavity 30 with the burner cap seat 10. A plurality of main fire holes 21 are formed on the circumferential side wall of the outer ring burner cap 20 at intervals and evenly distributed along its circumferential direction. Each main fire hole 21 communicates with the outer ring gas mixing cavity 30. The mixed gas enters the outer ring gas mixing cavity 30, and then burns after being discharged from the outer ring main fire holes 21 to form an annular outer ring flame, which can make the flame distribution uniform, so that the cookware and cooking utensils heated by the burner are heated evenly.
[0037] Specifically, the fire cover seat 10 can be configured as an open bowl-shaped structure. When the outer ring fire cover 20 is placed on the fire cover seat 10, the outer ring fire cover 20 can cover the open mouth of the fire cover seat 10, so that the fire cover seat 10 and the outer ring fire cover 20 together constitute the inner wall of the outer ring gas mixing chamber 30. The gas can be input into the outer ring gas mixing chamber 30 through the ejector pipe. The outer ring gas mixing chamber 30 can be specifically configured as an annular structure. In this way, when the gas is input into the outer ring gas mixing chamber 30, it can be evenly distributed along the circumference of the outer ring gas mixing chamber 30.
[0038] It can be seen that the flame generated by the burner is mainly distributed at the main fire hole 21 of the outer ring fire cover 20, so the temperature of the outer ring fire cover 20 is the highest, which can reach 300℃~500℃. Since the outer ring fire cover 20 is placed on the fire cover seat 10, the contact area between the two is relatively large. The heat of the outer ring fire cover 20 will be transferred to the fire cover seat 10, so that the temperature of the fire cover seat 10 will also reach this temperature. The fire cover seat 10 made of ordinary aluminum is easy to melt or deform when used in this high temperature state for a long time. At present, in the market, the fire cover seat 10 is often made of high-temperature resistant aluminum to solve the problem that the fire cover seat 10 is easy to melt or deform when used in a high temperature state for a long time. However, this will undoubtedly increase the production cost of the product.
[0039] Therefore, in order to solve the above problems, Figure 1 As shown, the outer ring fire cover 20 is provided with a plurality of heat dissipation grooves 22 spaced apart along the circumference thereof, and the heat dissipation grooves 22 are arranged adjacent to the main fire hole 21. Figure 1 It can be seen that the main fire hole 21 is located near the top on the circumferential side wall of the outer ring fire cover 20 , and the heat dissipation groove 22 extends a certain length along the axial direction of the outer ring fire cover 20 .
[0040] Combination Figure 3 and Figure 4 , by setting a heat dissipation groove 22 near the main fire hole 21, the heat dissipation area is increased. When the gas g is ejected outward through the main fire hole 21, the gas flow rate at the main fire hole 21 is large, so the pressure is small, which will drive the cold air c below it to flow upward and pass through the heat dissipation groove 22. When the external cold air c passes through the heat dissipation groove 22, the cold air c will take away part of the heat of the outer ring fire cover 20 and turn into hot air h, and be discharged from the top of the heat dissipation groove 22, so as to achieve the exchange of heat to the cold air c, thereby reducing the temperature of the part of the outer ring fire cover 20 provided with the heat dissipation groove 22. Since this part of the outer ring fire cover 20 is also in contact with the fire cover seat 10, the heat of the fire cover seat 10 will be conducted to the outer ring fire cover 20, thereby reducing the temperature of the fire cover seat 10, solving the problem that the fire cover seat 10 is easy to melt or deform when used under high temperature for a long time, and will not increase the production cost of the product. Secondly, by setting the heat dissipation groove 22, it can also promote air to enter the flame through the heat dissipation groove 22, promote the full combustion of the gas, and achieve the effect of enhancing the flame.
[0041] In an alternative embodiment, as Figure 1 shown, along the circumferential direction of the outer ring burner cap 20, the heat dissipation grooves 22 are located beside the main fire holes 21, and the heat dissipation grooves 22 and the main fire holes 21 are arranged alternately in sequence. That is to say, one heat dissipation groove 22 is provided on both sides of each main fire hole 21. With this setting, uniform cooling of the outer circumferential part of the outer ring burner cap 20 can be achieved, and the heat dissipation and cooling effect is better.
[0042] In an alternative embodiment, as Figure 2 shown, along the axial direction of the outer ring burner cap 20, one end of the heat dissipation groove 22 is close to the upper edge of the outer ring burner cap 20, and the other end of the heat dissipation groove 22 extends to the contact surface 24 between the outer ring burner cap 20 and the burner cap base 10. With this setting, it can be ensured that the heat dissipation groove 22 has a sufficient length, so as to ensure that the cold air has a sufficient flow path, realize sufficient heat exchange, achieve a better cooling effect, and when the temperature at the heat dissipation groove 22 on the outer ring burner cap 20 decreases, since the bottom of the heat dissipation groove 22 extends to the contact surface 24, the heat of the burner cap base 10 can be transferred to the heat dissipation groove 22 of the outer ring burner cap 20 faster through the contact surface 24, realizing the rapid cooling of the burner cap base 10.
[0043] In an alternative embodiment, as Figure 1 shown, each heat dissipation groove 22 includes two side surfaces 222 and a bottom surface 221. The two side surfaces 222 are arranged at intervals relative to each other along the circumferential direction of the outer ring burner cap 20, and the bottom surface 221 is connected between the two side surfaces 222. That is to say, when the cold air flows through the heat dissipation groove 22, three sides of the heat dissipation groove 22 are dissipating heat, increasing the heat dissipation area, greatly accelerating the heat exchange with the cold air, and thus the cooling effect is better.
[0044] In an alternative embodiment, as Figure 2 shown, the bottom surface 221 of the heat dissipation groove 22 can be an arc surface. This form of heat dissipation groove 22 is convenient for processing, and the arc surface extends to the contact surface 24, so that the cold air can enter the heat dissipation groove 22 more smoothly from below along the arc surface, and can flow more smoothly along the arc surface in the heat dissipation groove 22, accelerating the heat exchange and improving the heat dissipation efficiency.
[0045] In an alternative embodiment, as Figure 3 and Figure 4 shown, along the direction away from the axis of the outer ring burner cap 20, the main fire holes 21 are arranged to incline upwards. With this setting, the gas g can be ejected obliquely upwards after passing through the main fire holes 21, so that the gas flow velocity at the upper part of the outer ring burner cap 20 is high and the pressure is small, and it is easier to drive the cold air c below to flow upwards and pass through the heat dissipation grooves 22. Therefore, this form of main fire holes 21 has a good drainage effect on the flow of cold air, accelerating the heat exchange and improving the heat dissipation efficiency.
[0046] Further, as shown in Figure 1 and Figure 4 , a flame stabilizing groove 23 is further provided on the circumferential side wall of the outer ring burner cap 20. The flame stabilizing groove 23 extends along the circumferential direction of the outer ring burner cap 20. The flame stabilizing groove 23 is located below the main fire holes 21 and communicates with the main fire holes 21. The flame stabilizing groove 23 is annular or in the form of multiple arc segments. The gas in the outer ring gas mixing cavity 30 can enter the flame stabilizing groove 23 through the main fire holes 21 for combustion, and the flame stabilizing groove 23 can play a role in stabilizing the flame of the main fire holes 21.
[0047] In an optional embodiment, as shown in Figure 1 and Figure 3 , four outer ring gas channels 40 are formed between the outer ring burner cap 20 and the burner cap base 10. The four outer ring gas channels 40 are arranged at equal intervals along the circumferential direction of the outer ring gas mixing cavity 30 and are all communicated with the outer ring gas mixing cavity 30. The mixed gas is shunted through the four outer ring gas channels 40 and then enters the outer ring gas mixing cavity 30 respectively. The gas distribution uniformity is improved through channel shunting, thereby optimizing the state during flame combustion. In other embodiments, the number of the outer ring gas channels 40 can also be set to other values, which can be flexibly set according to actual needs and will not be specifically limited herein.
[0048] Specifically, in combination with Figure 1 and Figure 2 , both the burner cap base 10 and the outer ring burner cap 20 are circular bowl-shaped structures. Four evenly arranged air intake grooves are concavely provided on one side of the burner cap base 10 close to the outer ring burner cap 20, and four evenly arranged air intake grooves are also concavely provided on one side of the outer ring burner cap 20 close to the burner cap base 10. After the outer ring burner cap 20 is covered on the burner cap base 10, the air intake grooves on the outer ring burner cap 20 and the air intake grooves on the burner cap base 10 jointly enclose the above-mentioned outer ring gas channels 40, and the burner cap base 10 and the outer ring burner cap 20 are fixedly connected by a plurality of screws.
[0049] In an optional embodiment, as shown in Figure 1 , along the direction away from the axis of the outer ring burner cap 20, the width of the outer ring gas channel 40 gradually increases. The outer ring gas channel 40 adopts an expanding structure design, so that the pressure of the gas can be reduced when the gas passes through the outer ring gas channel 40, and its flow capacity is enhanced.
[0050] Further, the burner cap assembly may further include a central burner cap (not shown). The central burner cap is fastened to the center of the burner cap base 10, and the central burner cap and the burner cap base 10 can enclose a closed inner ring gas mixing cavity. The outer ring gas mixing cavity 30 surrounds the inner ring gas mixing cavity. A circle of inner ring main fire holes is provided on the outer side wall of the central burner cap. The inner ring main fire holes are communicated with the inner ring gas mixing cavity. The mixed gas enters the inner ring gas mixing cavity, and then burns after being discharged from the inner ring main fire holes to form an inner ring flame. Cooperating with the outer ring flame formed by the outer burner cap 20, the cookware and cooking utensils to be heated can be heated more evenly.
[0051] This embodiment also provides a burner, which includes a burner head (not shown) and the above-mentioned burner cap assembly. The burner cap base 10 of the burner cap assembly is covered above the burner head. By providing the above-mentioned burner cap assembly, the burner provided in this embodiment can reduce the temperature of the burner cap base 10, solve the problem that the burner cap base 10 is prone to melting or deformation when used at a high temperature for a long time, and does not increase the production cost of the product.
[0052] Specifically, the burner head includes a cylinder body, an outer injection pipe and an inner injection pipe which are respectively communicated with the cylinder body. The bottom of the burner cap base 10 is covered on the cylinder body. The cylinder body includes an independent outer ring gas mixing channel and an inner ring gas mixing channel. The outer injection pipe is communicated with the outer ring gas mixing channel and is used for introducing the mixed gas of gas and air into the outer ring gas mixing channel. The burner cap base 10 is fastened on the cylinder body, and the outer ring gas mixing channel is communicated with the outer ring gas mixing cavity 30 through the outer ring gas channel 40; the inner injection pipe is communicated with the inner ring gas mixing channel and is used for introducing the mixed gas of gas and air into the inner ring gas mixing channel. The inner ring gas mixing channel is communicated with the inner ring gas mixing cavity.
[0053] During use, the gas is sprayed into the outer injection pipe through the outer ring nozzle. The gas and air are mixed in the outer ring gas mixing channel to form a mixed gas. The mixed gas enters the outer ring gas mixing cavity 30 through each outer ring gas channel 40, and then burns after being discharged from the main fire hole 21 to form an outer ring flame, realizing the heating of the edge area of the bottom of the cookware. At the same time, the gas is sprayed into the inner injection pipe through the inner ring nozzle. The gas and air are mixed in the inner ring gas mixing channel to form a mixed gas. The mixed gas enters the inner ring gas mixing cavity, and then burns after being discharged from the inner ring main fire hole to form an inner ring flame, realizing the heating of the central area of the bottom of the cookware.
[0054] This embodiment also provides a gas stove, which mainly includes a gas valve, a gas path connecting unit and the above-mentioned burner. Among them, the inlet of the gas valve is communicated with an external gas supply source, and the outlet of the gas valve is respectively communicated with the inner injection pipe and the outer injection pipe of the burner through the gas path connecting unit. The gas valve is used for the user to operate to control whether the gas enters the burner for combustion and to control the amount of gas entering the burner, so as to realize that the burner cooks the cookware in different modes. Among them, the specific structure and working principle of the gas stove are prior art and will not be elaborated here.
[0055] The gas stove provided by this embodiment can reduce the temperature of the burner base 10 by setting the above-mentioned burner, solve the problem that the burner base 10 is prone to melting or deformation when used at high temperature for a long time, and does not increase the production cost of the product.
