[0022] The present utility model provides the following description with reference to the 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.

[0023] In the description of the present utility model, the orientation description is involved. For example, the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and 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 therefore cannot be understood as a limitation to the present utility model.

[0024] 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.

[0025] Embodiments of the present utility model provide a compact soup cooking and stewing valve body, such as Figures 1-4As shown, it includes a valve body 100, a valve stem 200, an angle sensor 300, a second electronic control valve 420 and a controller. The valve body 100 is provided with an air inlet passage, an inner ring gas transmission passage 110 and an outer ring gas transmission passage 120, and both the inner ring gas transmission passage 110 and the outer ring gas transmission passage 120 are connected to the air inlet passage. The air inlet passage is used to connect to an external gas pipeline to receive the gas transported externally, and then the gas flows to the inner ring gas transmission passage 110 and the outer ring gas transmission passage 120. The inner ring gas transmission passage 110 is used to eject gas into the inner ring mixing chamber of the burner for forming an inner ring flame, and the outer ring gas transmission passage 120 is used to eject gas into the outer ring mixing chamber of the burner for forming an outer ring flame. The second electronic control valve 420 is used to control the flow rate of the outer ring gas transmission passage 120, and specifically can close the outer ring gas transmission passage 120, fully open the outer ring gas transmission passage 120 or partially open the outer ring gas transmission passage 120.

[0026] The valve stem 200 is arranged on the valve body 100 and can rotate, and the user can rotate the valve stem 200 by himself. An adjusting device connected to the valve stem 200 is arranged in the valve body 100. When the valve stem 200 rotates, the adjusting device also rotates with the valve stem 200, thereby changing the flow rates of the inner ring gas transmission passage 110 and the outer ring gas transmission passage 120. Since the adjusting device is a device configured in the existing gas stove valve body and already belongs to the prior art, its specific structure will not be described in detail.

[0027] The angle sensor 300 is connected to the valve stem 200 to detect the angle of the valve stem 200. Both the angle sensor 300 and the second electronic control valve 420 are connected to the controller. The angle sensor 300 can send the detected angle to the controller, and the controller can send a control signal to the second electronic control valve 420 to enable the second electronic control valve 420 to control the flow rate of the outer ring gas transmission passage 120 respectively. At the same time, combined with the inherent function that the adjusting device can change the flow rates of the inner ring gas transmission passage 110 and the outer ring gas transmission passage 120 as it rotates with the valve stem 200, the inner ring flame and the outer ring flame can be intelligently controlled to meet the diverse needs of users such as cooking soup and stewing.

[0028] In this embodiment, the controller may include a single-chip microcomputer, a PLC or other control chips, and the electronic control valve may be a solenoid valve.

[0029] In some embodiments, when the angle sensor 300 detects that the valve stem 200 is at the first angle, the controller controls the second electrically controlled valve 420 to open, and the adjusting device also opens the inner ring gas supply channel 110, so as to achieve that both the inner ring flame and the outer ring flame are large flames, which can be used by the user for stir-frying. When the angle sensor 300 detects that the valve stem 200 is at the second angle, the controller controls the second electrically controlled valve 420 to close, and the adjusting device still keeps the inner ring gas supply channel 110 open, so as to achieve a large inner ring flame and an extinguished outer ring flame. When the angle sensor 300 detects that the valve stem 200 is at the third angle, the controller controls the second electrically controlled valve 420 to open, and the adjusting device adjusts the inner ring gas supply channel 110 to a small opening degree, so as to achieve a small inner ring flame and a large outer ring flame; wherein, the third angle is greater than the second angle, and the second angle is greater than the first angle, so that the user can twist the valve stem 200 in the same direction, and the valve stem 200 can reach the first angle, the second angle and the third angle in sequence.

[0030] Further, the initial angle of the valve stem 200 is 0°, the first angle is 90°, the second angle is 170°, and the third angle is 230°.

[0031] In some embodiments, as Figures 1-4 shown, the valve body 100 is further provided with a connecting groove 150, and the connecting groove 150 is communicated with the air inlet channel. The second electrically controlled valve 420, the connecting groove 150 and the outer ring gas supply channel 120 are coaxially arranged, and the connecting groove 150 is located at the inlet end of the outer ring gas supply channel 120 and is communicated with the outer ring gas supply channel 150; the second electrically controlled valve 420 is fixed on the outer end surface of the connecting groove 150, and the air inlet channel forms an air inlet 101 on the surface of the valve body 100; in the air flow direction of the outer ring gas supply channel 120, the whole second electrically controlled valve 420 is located in front of the outer end surface 102 of the air inlet 101, that is, the second electrically controlled valve 420 does not protrude from the rear side of the outer end surface 102 of the air inlet 101. Therefore, in this embodiment, the space at the inlet end of the outer ring gas supply channel 150 is used to install the second electrically controlled valve 420, so that the structure of the whole valve body is closer and more compact, and the space occupation is reduced.

[0032] In this embodiment, the valve head 421 of the second electrically controlled valve 420 can extend into the connecting groove 150, the valve head 421 can move along the air flow direction of the outer ring gas supply channel 120, and the valve head 421 is used to cover or open the inlet end of the outer ring gas supply channel 120 to control the flow rate of the outer ring gas supply channel 120.

[0033] Further, the valve body 100 of this embodiment is further provided with a connection channel 130 and a branch channel 140. The inner ring gas transmission channel 110, the outer ring gas transmission channel 120, and the connection channel 130 are arranged in parallel. The outer ring gas transmission channel 120, the connection groove 150, and the second electric control valve 420 are all located on the side of the connection channel 130 away from the inner ring gas transmission channel 110. The air inlet channel, the connection channel 130, the branch channel 140, and the connection groove 150 are connected in sequence, so that the connection groove 150 can communicate with the air inlet channel. At the same time, the connection channel 130 is located between the inner ring gas transmission channel 110 and the outer ring gas transmission channel 120, reasonably utilizing the space formed by the need to have a certain distance between the inner ring gas transmission channel 110 and the outer ring gas transmission channel 120 itself, making the overall structure more compact.

[0034] In some embodiments, as Figures 1-4 shown, the valve body 100 is further provided with a spare channel 160. One end of the spare channel 160 communicates with the outer ring gas transmission channel 120, and a plugging member 161 is detachably fixed at the other end. When the spare channel 160 needs to be used, the plugging member 161 is removed, and the spare channel 160 can output gas. For example, the spare channel 160 can inject gas into the central mixing chamber of the three-ring fire burner to make the central fire burn.

[0035] In this embodiment, the plugging member 161 can be a screw. An internal thread adapted to the screw is provided at the outlet position of the spare channel 160, and the plugging member 161 is threadedly connected to the spare channel 160, which is convenient for the installation and removal of the plugging member 161.

[0036] In some embodiments, the branch channel 140 is inclined with respect to the extending direction of the connection channel 130. In the direction from the connection channel 130 to the connection groove 150, the branch channel 140 gradually extends backward. This structure is convenient for drilling holes in the inner wall of the connection groove 150 to form the branch channel 140, simplifying the forming process of the branch channel 140.

[0037] In some embodiments, the angle sensor 300 includes a potentiometer or an encoder. The rotating shaft of the potentiometer can be connected to the valve stem 200, and the encoder can be sleeved outside the valve stem 200.

[0038] In some embodiments, the compact soup-making and stewing valve body of this embodiment further includes a first electric control valve 410, and the first electric control valve 410 is used to control the flow rate of the air inlet channel to control the total gas delivery volume.

[0039] The terms and words used in the above description and claims are not limited to their literal meanings, but are 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 description of the various embodiments of the present utility model provided above is only for the purpose of illustration and not for the purpose of limiting the present utility model as defined by the appended claims and their equivalents.
