[0001] The utility model relates to the technical field of gas stove valve bodies, in particular to a stir-fry valve body with a compact structure. Background Art

[0002] To cater to the high-powered stir-frying habits of some users, many gas stoves are equipped with a stir-fry function. For example, Chinese utility model patent publication number CN220601563U discloses a gas stove with a stir-fry function. Although the valve body of this gas stove can control stir-frying, the throttle is integrally machined from the valve body, making it difficult to control machining precision and resulting in large thermal load deviations. Furthermore, the on-off valve is located on the side of the outer ring outlet, parallel to the nozzle at the outer ring outlet. This results in a large valve body and occupies a lot of space. When the on-off valve is closed, it is subject to the thrust of the gas, posing a risk of leakage. Utility Model Content

[0003] The utility model provides a stir-fry valve body with a compact structure, which can be used for stir-fry control. The overall structure is compact, which reduces space occupation and reduces the risk of thermal load deviation and air leakage.

[0022] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0023] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0024] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0025] The embodiment of the present utility model provides a stir-fry valve body with a compact structure, such as Figure 1 and Figure 2As shown, it includes a valve body 100 and a first control valve 200. The valve body 100 is provided with an air intake channel, an inner ring gas supply channel 110, a connecting channel 120, a first branch channel 131, a connecting groove 140 and an outer ring gas supply channel 150. The inner ring gas supply channel 110 is connected to the air intake channel, and the air intake channel, the connecting channel 120, the first branch channel 131 and the outer ring gas supply channel 150 are connected in sequence. The air intake channel is used to connect to an external gas pipeline to receive gas transported from the outside, and the gas then flows to the inner ring gas supply channel 110 and the outer ring gas supply channel 150. The inner ring gas supply channel 110 is used to inject gas into the inner ring mixing chamber of the burner to form an inner ring fire, and the outer ring gas supply channel 150 is used to inject gas into the outer ring mixing chamber of the burner to form an outer ring fire. A throttling member 300 is fixed in the first branch channel 131 to throttle the first branch channel 131. The connecting groove 140 is connected to the connecting channel 120 and the outer ring gas supply channel 150. The first control valve 200 is used to control whether the connecting groove 140 and the outer ring gas supply channel 150 are connected or disconnected. When the first control valve 200 controls the connection between the connecting groove 140 and the outer ring gas supply channel 150, the pressure in the outer ring gas supply channel 150 increases, the output gas volume increases, and the outer ring can be stir-fried. When the first control valve 200 controls the connection between the connecting groove 140 and the outer ring gas supply channel 150 to be disconnected, gas is only supplied to the outer ring gas supply channel 150 through the first branch channel 131, and the outer ring fire burns normally. In this way, the first control valve 200 can achieve control of the stir-fry function.

[0026] The first control valve 200, the connecting groove 140, and the outer ring gas transmission channel 150 are coaxially arranged, and the connecting groove 140 is located at the inlet end of the outer ring gas transmission channel 150, and the connecting groove 140 is connected to the inlet end of the outer ring gas transmission channel 150. The first control valve 200 is fixed to the outer end surface of the connecting groove 140, and the air inlet channel forms an air inlet 101 on the surface of the valve body 100. In the direction of airflow in the outer ring gas transmission channel 150, the entire first control valve 200 is located in front of the outer end surface 102 of the air inlet 101, that is, the first control valve 200 does not protrude from the rear side of the outer end surface 102 of the air inlet 101. Therefore, this embodiment utilizes the space at the inlet end of the outer ring gas transmission channel 150 to install the first control valve 200, making the structure of the entire valve body more compact and reducing space occupation.

[0027] The throttle member 300 is an independent component and is not integrally formed with the valve body 100. It is fixed in the first branch channel 131. Therefore, the throttle member 300 can be independently processed or use a standard component, which reduces the difficulty of processing, improves the processing accuracy, and reduces the thermal load deviation; when the first control valve 200 is closed, under the action of the gas pressure, the first control valve 200 can further maintain the closed state, reducing the risk of gas leakage.

[0028] In this embodiment, the valve head 210 of the first control valve 200 can extend into the connecting groove 140. The movement direction of the valve head 210 is parallel to the airflow direction of the outer ring gas transmission channel 150. The valve head 210 is used to cover or open the inlet end of the outer ring gas transmission channel 150 to control the flow rate of the outer ring gas transmission channel 150. The first control valve 200 includes a drive rod connected to the valve head 210, which drives the valve head 210 to move. The drive rod can be arranged coaxially with the outer ring gas transmission channel 150. While the first control valve 200 is fixed to the outer end surface of the connecting groove 140, it can cover the opening of the connecting groove 140 to ensure sealing.

[0029] In some embodiments, as Figure 1 and Figure 3 As shown, the throttle member 300 is a throttle valve core 310 having a through throttle hole 311 through which the gas passes to achieve throttling of the gas. In the direction of gas flow, the aperture of the throttle hole 311 first gradually decreases and then gradually increases.

[0030] Furthermore, an annular groove 312 is provided on the outer side of the throttle valve core 310 , and a sealing ring 320 is embedded in the annular groove 312 to fix the sealing ring 320 . The sealing ring 320 abuts against the inner wall of the first branch channel 131 to improve the sealing performance.

[0031] In some embodiments, as Figure 1 As shown, valve body 100 is further provided with a second branch channel 132, the two ends of which are connected to connecting channel 120 and connecting groove 140, respectively. Second branch channel 132 is arranged at an angle, gradually tilting toward the rear side of outer ring gas transmission channel 150 in the direction from connecting channel 120 to connecting groove 140. This structure facilitates oblique drilling on the inner wall of connecting groove 140 to form second branch channel 132, simplifying the molding process of second branch channel 132.

[0032] In some embodiments, as Figure 1 As shown, the valve body 100 is further provided with a backup channel 160. One end of the backup channel 160 is connected to the outer ring gas transmission channel 150, and the other end is detachably fixed with a blocking member 400. When the backup channel 160 is needed, the blocking member 400 is removed, and the backup channel 160 can output gas. For example, the backup channel 160 can be used to inject gas into the central mixing chamber of a triple-ring burner to activate the central fire.

[0033] In this embodiment, the blocking member 400 may be a screw, and an internal thread compatible with the screw is provided at the outlet of the spare channel 160 . The blocking member 400 is threadedly connected to the spare channel 160 , facilitating installation and removal of the blocking member 400 .

[0034] In some embodiments, the compact stir-fry valve body further includes a second control valve 500 , which is used to control the flow of the air intake channel to perform overall control of the flow of the inner ring gas transmission channel 110 and the outer ring gas transmission channel 150 .

[0035] In some embodiments, the first control valve 200 and the second control valve 500 of the above embodiments are both solenoid valves.

[0036] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
