However, it is found in the actual use process that the firepower range adjusted by the valve body is limited, and the use cost and maintenance cost of the valve body are relatively high, which cannot meet the needs of users. Content of the Utility Model

The gas mixing chamber includes a connecting part communicating with the middle ring fire cover and the outer ring fire cover. The connecting part protrudes from the top of the gas mixing chamber. The middle ring fire cover and the outer ring fire cover are integrally formed into a cover body and are arranged on the connecting part. The connecting part is symmetrically arranged with the axis of the gas mixing chamber and the connecting line between the edge of the gas mixing chamber as the axis of symmetry. Different-sized first channels and second channels are arranged in the connecting part. The cover body is provided with a first interface and a second interface corresponding to the first channel and the second channel. The first interface is used to communicate with the middle ring fire cover, and the second interface is used to communicate with the outer ring fire cover;

[0053] The following gives a preferred embodiment and combines with the accompanying drawings to more clearly and completely illustrate the present utility model.
[0054] This embodiment provides a burner, and the specific structure is as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown. The burner includes a mixing chamber 1, an inner ring burner cap 2, a middle ring burner cap 3 and an outer ring burner cap 4. The mixing chamber 1 includes a connecting part 10 connecting the middle ring burner cap 3 and the outer ring burner cap 4. The connecting part 10 protrudes from the top of the mixing chamber 1. The middle ring burner cap 3 and the outer ring burner cap 4 are integrally formed into a cover body 20 and are arranged on the connecting part 10. The connecting part 10 is symmetrically arranged with the axis of the mixing chamber 1 and the connecting line between the edge of the mixing chamber 1 as the axis of symmetry. The connecting part 10 is internally provided with a first channel 11 and a second channel 12 with different sizes. The cover body 20 is provided with a first interface 21 and a second interface 22 corresponding to the first channel 11 and the second channel 12. The first interface 21 is used to communicate with the middle ring burner cap 3, and the second interface 22 is used to communicate with the outer ring burner cap 4;
[0055] When the cover body 20 and the communication part 10 are in the first state, the first interface 21 communicates with the first channel 11 correspondingly, and the second interface 22 communicates with the second channel 12 correspondingly. When the cover body 20 and the communication part 10 are in the second state, the first interface 21 communicates with the second channel 12, and the second interface 22 communicates with the first channel 11 correspondingly. The second state is that the cover body 20 in the first state rotates 180° around the axis of the gas mixing chamber 1.
[0056] Specifically, the gas mixing chamber 1 is a circular plate and is covered on the base to form a cavity for accommodating gas with the base. The top of the gas mixing chamber 1, that is, the top of the circular plate, is provided with a communication part 10 protruding in the direction away from the base. The communication part 10 is an arc-shaped structure and is arranged near the edge of the circular plate. The communication part 10 is provided with a first channel 11 and a second channel 12 with different sizes. Both the first channel 11 and the second channel 12 are arc-shaped holes so that gas can flow into the middle ring burner cap 3 and the outer ring burner cap 4. The communication part 10 is symmetrically arranged with the axis of the gas mixing chamber 1 and the connection line between the edge of the gas mixing chamber 1 as the axis of symmetry, that is, two communication parts 10 are arranged on the top of the gas mixing chamber 1. Correspondingly, the middle ring burner cap 3 and the outer ring burner cap 4 are integrally formed into a cover body 20. The cover body 20 is a circular ring structure, and the circular ring structure is used to cover the two communication parts 10. The bottom of the cover body 20 is provided with a first interface 21 and a second interface 22 corresponding to the two communication parts 10. The sizes of the first interface 21 and the second interface 22 correspond to the first channel 11 and the second channel 12 with different sizes in the communication part 10. The first interface 21 communicates with the fire holes of the middle ring burner cap 3 along the thickness direction of the cover body 20, while the second interface 22 communicates with the fire holes of the outer ring burner cap 4 along the radial direction of the cover body 20, so as to change the gas flow direction on the integrally formed cover body 20 and prevent the gas from only being able to enter one of the middle ring burner cap 3 or the outer ring burner cap 4.
[0057] When the cover body 20 is covered on the communication part 10 and in the first state, the first interface 21 and the first channel 11, and the second interface 22 and the second channel 12 are in one-to-one correspondence and communication. At this time, both the middle-ring burner cap 3 and the outer-ring burner cap 4 are supplied with gas and burn. When the cover body 20 is covered on the communication part 10 and in the second state, since the cover body 20 rotates 180° around the axis of the mixing chamber 1, the first interface 21 and the second channel 12, and the second interface 22 and the first channel 11 are in corresponding communication. It can be understood that the sizes of the second channel 12 and the first channel 11 are different, resulting in a change in the gas volume entering the first interface 21 and flowing into the middle-ring burner cap 3. Similarly, the gas volume entering the second interface 22 and flowing into the outer-ring burner cap 4 also changes. By rotating, different connection states of the first channel 11, the second channel 12, the first interface 21, and the second interface 22 are realized, that is, the gas volume is adjusted in the first state and the second state, thereby adjusting the firepower distribution on the cover body 20, so that the burner can achieve the adjustment of firepower and the redistribution of the flame shape without setting a valve body, thereby reducing the manufacturing and use costs of the burner with the firepower adjustment function, increasing the firepower range, being applicable to different users and being able to meet the users' needs for different firepowers.
[0058] In this embodiment, the size of the first channel 11 is larger than that of the second channel 12. It can be understood that when the size of the first channel 11 is larger than that of the second channel 12, more gas enters the middle-ring burner cap 3 in the first state to meet the user's demand for a larger firepower of the middle-ring burner cap 3 in the first state. Of course, in the second state, the firepower of the outer-ring burner cap 4 increases while the firepower of the middle-ring burner cap 3 decreases to realize the change in the firepower of the middle-ring burner cap 3 in the second state.
[0059] Further, in this embodiment, the edge of the first channel 11 close to the second channel 12 extends towards the second channel 12, and the edge of the first interface 21 close to the second interface 22 corresponds to the edge of the first channel 11 close to the second channel 12 and extends towards the second interface 22, and when the cover body 20 is in the second state, the edge of the first channel 11 close to the second channel 12 and the edge of the first interface 21 close to the second interface 22 enclose an air supplement channel 5.
[0060] Specifically, the outlets of the first channel 11 and the second channel 12 are both arc-shaped holes. The outlet of the first channel 11 has a groove 111 near the edge of the second channel 12. The groove 111 can be a rectangular groove or a shape in other prior arts, such as an arc-shaped groove or an oval groove. This is prior art and will not be elaborated here. The groove 111 communicates with the first channel 11, that is, it can allow gas to flow into the cover body 20. Correspondingly, the outlet of the first interface 21 also has a groove 111 near the edge of the second interface 22. In the first state, the first channel 11 corresponds to the first interface 21, and the two grooves 111 also correspond to each other. That is, by setting the groove 111, the size of the outlet of the first channel 11 is increased. In the second state, the first channel 11 corresponds to the second interface 22. At this time, the groove 111 at the outlet of the first channel 11 and the groove 111 at the outlet of the first interface 21 enclose a gas supplement channel 5 along the thickness direction of the cover body 20. The gas in the gas supplement channel 5 can correspondingly flow into the first interface 21 of the cover body 20, and then supplement the gas to the middle ring burner cap 3 in the second state, avoiding the situation of flashback of the middle ring burner cap 3 due to insufficient gas volume when it is connected to the second channel 12.
[0061] As Figure 6 shown, in other embodiments, the outlet edges of the first channel 11 and the second channel 12 are flush edges, that is, the groove 111 is not provided, so as to correspond to the inlet edges of the first interface 21 and the second interface 22 and maintain the sealing performance during gas flow in the first state.
[0062] As Figure 7 and Figure 8 shown, in this embodiment, the outlet of the second channel 12 is a blind hole. When the cover body 20 is in the first state, the outer ring burner cap 4 is closed and the middle ring burner cap 3 is opened. When the cover body 20 is in the second state, the middle ring burner cap 3 is supplied with gas through the gas supplement channel 5 and the firepower is reduced, while the outer ring burner cap 4 is opened.
[0063] Specifically, the outlet of the second channel 12 is a blind hole, that is, the second channel 12 is closed, and gas is supplied to the cover body 20 only through the first channel 11. When in the first state, the first channel 11 is communicated with the first interface 21, and no gas flows into the second interface 22 because the second channel 12 is closed, resulting in the middle ring burner cap 3 of the cover body 20 being opened and the outer ring burner cap 4 being closed. When in the second state, the cover body 20 rotates. Correspondingly, the second interface 22 is communicated with the first channel 11, and the first interface 21 is communicated with the second channel 12. It can be understood that since the first channel 11 is provided with a groove 111 and the first interface 21 is provided with a groove 111 to form a gas supplementing channel 5 in the second state. When the second channel 12 is closed, gas is supplied to the first interface 21 only through the gas supplementing channel 5. At this time, the firepower of the middle ring burner cap 3 is reduced compared with that in the first state, while the outer ring burner cap 4 is correspondingly opened due to sufficient gas supply and burns fully, thereby increasing the heating area of the burner and making the heating more uniform, so as to meet the different requirements of users for firepower, and the firepower adjustment of the burner can be realized without setting a valve body.
[0064] As Figure 9 shown, in other embodiments, the outlet of the first channel 11 is a blind hole. When the cover body 20 is in the first state, the middle ring burner cap 3 is closed and the outer ring burner cap 4 is opened. When the cover body 20 is in the second state, the outer ring burner cap 4 is supplied with gas through the gas supplementing channel 5 and the firepower is reduced, while the middle ring burner cap 3 is opened.
[0065] Specifically, the outlet of the first channel 11 is a blind hole, that is, the first channel 11 is closed, and gas is supplied to the cover body 20 only through the second channel 12. When in the first state, the second channel 12 is communicated with the second interface 22, and no gas flows into the first interface 21 because the first channel 11 is closed, resulting in the outer ring burner cap 4 of the cover body 20 being opened and the middle ring burner cap 3 being closed. When in the second state, the cover body 20 rotates. Correspondingly, the first interface 21 is communicated with the second channel 12, and the second interface 22 is communicated with the first channel 11. It can be understood that since the first channel 11 is provided with a groove 111 and the first interface 21 is provided with a groove 111 to form a gas supplementing channel 5 in the second state. It can be understood that when the outlet of the first channel 11 is closed, the groove 111 is not affected and can pass gas, that is, when the first channel 11 is closed, gas can be supplied to the second interface 22 through the gas supplementing channel 5. At this time, the firepower of the outer ring burner cap 4 is reduced compared with that in the first state, while the middle ring burner cap 3 is correspondingly opened due to sufficient gas supply and burns fully, thereby making the burner heat more centered during heating and meeting the different cooking requirements of users.
[0066] It should be noted that, due to the different heights of the two grooves 111 of the air supplement channel 5 in the thickness direction of the cover body 20, in the second state, in addition to the air supplement channel 5, part of the gas in the second channel 12 can also flow into the second interface 22, so as to prevent flashback of the outer ring burner cap 4, and at the same time avoid the flame lift of the middle ring burner cap 3 caused by excessive gas volume, thereby improving the use safety of the burner.
[0067] As Figure 10 shown, in another embodiment, among the symmetrically arranged connecting parts 10, the outlet of the first channel 11 of one connecting part 10 is a blind hole, and the outlet of the second channel 12 of the other connecting part 10 is a blind hole. When the cover body 20 is in the first state, both the middle ring burner cap 3 and the outer ring burner cap 4 are opened, and the firepower of the middle ring burner cap 3 is greater than that of the outer ring burner cap 4. When the cover body 20 is in the second state, the firepower of the outer ring burner cap 4 is greater than that of the middle ring burner cap 3;
[0068] Or when the cover body 20 rotates 180° from the first state in the direction away from the second state, the firepower of the middle ring burner cap 3 is greater than that of the outer ring burner cap 4.
[0069] Specifically, in the two connecting parts 10, the outlet of the first channel 11 of one connecting part 10 is closed, and the outlet of the second channel 12 of the other connecting part 10 is closed. In the first state, the second channel 12 of one connecting part 10 is connected to the corresponding first interface 21 in the cover body 20, and the first channel 11 of the other connecting part 10 is connected to the corresponding second interface 22 in the cover body 20, so as to realize the simultaneous opening of the middle ring burner cap 3 and the outer ring burner cap 4 and meet the user's firepower requirement for stir-frying. And in the second state, rotate the cover body 20. At this time, the second channel 12 of one connecting part 10 is connected to the corresponding second interface 22 in the cover body 20, and the first channel 11 of the other connecting part 10 is connected to the corresponding first interface 21 in the cover body 20. Since the size of the first channel 11 is larger than that of the second channel 12, the firepower of the middle ring burner cap 3 increases in the second state.
[0070] It can be understood that, due to the opposite settings of the outlets of the blind holes in the two connecting parts 10, that is, the outlet of the first channel 11 of one connecting part 10 is closed, and the outlet of the second channel 12 of the other connecting part 10 is closed. When the cover body 20 rotates 180° from the first state in the direction away from the second state, for example, originally rotating clockwise is changed to rotating counterclockwise, so that the first channel 11 of one connecting part 10 is connected to the corresponding second interface 22 in the cover body 20, and the second channel 12 of the other connecting part 10 is connected to the corresponding first interface 21 in the cover body 20. Since the size of the first channel 11 is larger than that of the second channel 12, when the cover body 20 rotates 180° from the first state in the direction away from the second state, the firepower of the middle ring burner cap 3 increases in the second state. To realize different firepower distributions of the burner and increase the range of firepower adjustment.
[0071] In this embodiment, the symmetrically arranged communication parts 10 are spaced apart, and when the cover body 20 covers the communication parts 10, there is a gap between the cover body 20 and the top surface of the gas mixing chamber 1, and the gap communicates with the inner ring burner cap 2.
[0072] Specifically, the communication parts 10 protrude to have a gap with the top of the gas mixing chamber 1. When the cover body 20 covers the communication parts 10, there is also a gap between the bottom of the cover body 20 and the top of the gas mixing chamber 1. Moreover, the symmetrically arranged communication parts 10 are spaced apart to enclose a secondary air intake passage for supplying external air to the inner ring burner cap 2, so that the inner ring burner cap 2 can supplement external air through the gap, ensuring the smooth combustion of the inner ring burner cap 2 and preventing the inner ring burner cap 2 from extinguishing due to the lack of air intake when the middle ring burner cap 3 and the outer ring burner cap 4 consume air during combustion. Additionally, it can be understood that the protruding communication parts 10 enable users to clean through the gap when cleaning the burner, preventing the accumulation of overflow liquid that cannot be cleaned and reducing the cleaning difficulty.
[0073] In this embodiment, the flame holes of the middle ring burner cap 3 are round holes, and the flame holes of the outer ring burner cap 4 are annular slit holes. The annular slit holes are the flame holes arranged in the annular groove in the prior art. Compared with the round holes, the flame shapes during combustion of the annular slit holes are different from those of the round holes, so as to achieve different flame shapes during the combustion of the middle ring burner cap 3 and the outer ring burner cap 4, improving the firepower range and heating uniformity.
[0074] In this embodiment, at least one sub-channel 6 is arranged in the first channel 11 and the second channel 12.
[0075] Specifically, the sub-channel 6 is a channel formed by the partition arranged at the outlet of the first channel 11 or the second channel 12 and the edge of the outlet of the first channel 11 or the second channel 12. Taking the example of arranging two sub-channels 6 at the outlet of the first channel 11 or the second channel 12, compared with supplying gas through a single channel arranged inside the outlet of the first channel 11 or the second channel 12, the range of the gas volume that can be provided to the middle ring burner cap 3 and the outer ring burner cap 4 is wider in the rotating state, and thus there is sufficient gas in the first channel 11 and the second channel 12 to be supplied to the middle ring burner cap 3 and the outer ring burner cap 4 when the cover body 20 is in the rotating state.
[0076] This embodiment provides a gas stove, and the gas stove includes the above-mentioned burner.
[0077] Specifically, the gas stove includes the above-mentioned burner to meet the heating function of the burner in the first state, and to achieve the switching of the firepower and the flame shape in the second state, without the need to additionally set a valve body or change the existing valve body structure, reducing the manufacturing and use costs.
[0078] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present utility model.
