[0025] The present utility model provides the following description with reference to the accompanying drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0026] In the description of the present utility model, when it comes to orientation descriptions, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., it is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0027] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.

[0028] An embodiment of the present utility model provides a stir-fry regulating valve, as Figures 1-5 shown, which includes a valve seat 100. An air inlet passage 110, an air outlet passage 120, and an adjustment hole 130 are provided on the valve seat 100. The adjustment hole 130 is communicated with the air inlet passage 110 through a connection hole 140, and the air outlet passage 120 is communicated with the adjustment hole 130. When not blocked or cut off, the air inlet passage 110, the connection hole 140, the adjustment hole 130, and the air outlet passage 120 are sequentially communicated. An adjustment member 200 is arranged in the adjustment hole 130. The adjustment member 200 includes an adjustment head 210 at one end thereof close to the connection hole 140. The adjustment member 200 is used to control the adjustment head 210 to block the connection hole 140. At the same time, the adjustment member 200 is also used to adjust the opening degree of the connection hole 140. The larger the opening degree of the connection hole 140, the greater the gas flow rate flowing out of the air outlet passage 120, and the greater the stir-fry firepower. On the contrary, the smaller the gas flow rate flowing out of the air outlet passage 120, the smaller the stir-fry firepower. Therefore, the adjustment of the stir-fry firepower can be realized in this embodiment.

[0029] A valve core passage 220 is provided on the adjustment member 200. One end of the valve core passage 220 forms a first opening 221 on the end face of the adjustment head 210, and the other end forms a second opening 222 communicating with the adjustment hole 130 on the surface of the adjustment member 200. As Figure 3As shown, when the adjusting head 210 blocks the connection hole 140, the first opening 221 is in communication with the connection hole 140, and a small amount of gas can enter the adjusting hole 130 through the valve core channel 220, and then flow out from the air outlet channel 120. Therefore, after the adjusting head 210 blocks the connection hole 140, it will not cause the stir-fry flame to go out, but uses the flow rate defined by the valve core channel 220 as the minimum firepower of the stir-fry firepower, ensuring the stability of the stir-fry firepower at the minimum firepower.

[0030] In some embodiments, the adjusting member 200 further includes a threaded portion 230, and the threaded portion 230 is threadedly connected to the adjusting hole 130. When the adjusting member 200 rotates in the adjusting hole 130, the adjusting member 200 will move along the axial direction of the adjusting hole 130, and then the adjusting head 210 approaches or moves away from the connection hole 140. The closer the adjusting head 210 is to the connection hole 140, the smaller the distance between the connection hole 140 and the adjusting head 210, and the smaller the opening degree of the connection hole 140. On the contrary, the farther the adjusting head 210 is from the connection hole 140, the larger the distance between the connection hole 140 and the adjusting head 210, and the larger the opening degree of the connection hole 140. Therefore, by rotating the adjusting member 200, the opening degree of the connection hole 140 can be adjusted, which is more convenient to operate.

[0031] In this embodiment, the adjusting member 200 can be a screw, a screw rod or other devices with a threaded portion 230.

[0032] Furthermore, the adjusting member 200 is an adjusting screw, and the head of the adjusting screw is away from the connection hole 140. Therefore, the head of the adjusting screw is arranged outward, and tools such as a screwdriver can be inserted into the adjusting hole 130 to screw the head of the adjusting screw, further improving the convenience of operation.

[0033] In this embodiment, the surface of the threaded portion 230 of the adjusting screw and the inner wall of the adjusting hole 130 are provided with threads that match each other to achieve the threaded connection between the threaded portion 230 and the adjusting hole 130.

[0034] In some embodiments, in the direction of approaching the connection hole 140 along the adjusting hole 130, the second opening 222 of the valve core channel 220 is located in front of the threaded portion 230. The threaded connection between the threaded portion 230 and the adjusting hole 130 has a certain sealing effect on the adjusting hole 130, so that the gas in the adjusting hole 130 will not leak out. At the same time, the gas flowing out from the second opening 222 can enter the adjusting hole 130 and then flow to the air outlet channel 120.

[0035] In some embodiments, a limiting member 300 is arranged in the adjusting hole 130. The limiting member 300 is used to limit the adjusting member 200 from moving out of the adjusting hole 130, so that the adjusting member 200 can be kept in the adjusting hole 130 to ensure its function of adjusting the size of the stir-fry firepower.

[0036] Further, the limiting member 300 is a limiting sleeve inserted into the adjusting hole 130. The limiting sleeve has a through perforation 310. The limiting sleeve can not only limit the adjusting member 200 from moving out of the adjusting hole 130, but also reserve the perforation 310 for tools such as screwdrivers to pass through the perforation 310 to adjust the adjusting member 200.

[0037] The limiting sleeve can be detachably connected to the adjusting hole 130 to facilitate installation and disassembly and the assembly of the adjusting member 200. Specifically, the limiting sleeve can be threadedly connected to the adjusting hole 130.

[0038] In some embodiments, one end of the connecting hole 140 connected to the adjusting hole 130 forms a tapered opening 141. In the direction along the connecting hole 140 from the intake passage 110 towards the adjusting hole 130, the inner diameter of the tapered opening 141 gradually increases. The adjusting head 210 is arranged in a tapered structure adapted to the tapered opening 141. When the adjusting head 210 plugs the connecting hole 140, the connecting head 210 is inserted into the tapered opening 141, thereby increasing the contact area with the inner wall of the tapered opening 141 and improving the plugging effect.

[0039] In some embodiments, the high-fire stir-fry regulating valve further includes an electric control valve 400 fixed on the valve seat 100. The electric control valve 400 is used to control the intake passage 110 to be blocked or conducted. After the intake passage 110 is blocked, the gas in the intake passage 110 cannot be delivered to the outlet passage 120, which will cause the high-fire stir-fry flame to go out. After the intake passage 110 is conducted, the size of the high-fire stir-fry flame can be adjusted by the adjusting member 200.

[0040] An embodiment of the present utility model provides a gas stove, including the high-fire stir-fry regulating valve of any of the above embodiments. For the specific description of the high-fire stir-fry regulating valve, reference can be made to the above embodiments and will not be elaborated herein.

[0041] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the present utility model. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present utility model is only for illustration and not for limiting the present utility model as defined by the appended claims and their equivalents.
