[0036] Embodiment 1: Figure 1 and Figure 3 The technical solution shown in the utility model provides the following technical solution: an energy-saving gas flow control device, disclosed:

[0037] The gas stove 1 comprises a bracket 3, which is installed on the lower surface of the gas stove 1, and a control valve 4 is nested and connected on the upper side of the inner surface of the bracket 3, and a control shaft 5 is rotatably connected to the inner surface of the control valve 4, and a connecting rod 6 is rotatably connected to the upper surface of the control shaft 5, and the connecting rod 6 is provided with a retractable gap control mechanism;

[0038] The bracket 3 and the gas stove 1 form an integrated structure, and the bracket 3 and the control valve 4 form a built-in nested structure, and the control valve 4 and the control shaft 5 form a midline rotation setting, while the control shaft 5 and the connecting rod 6 form an eccentric rotation structure, and the outer surface shape of the connecting rod 6 is a bent structure.

[0039] When in use, the gas stove 1 is installed in the use position, and the gas pipe 2 is assembled for air intake, and the bracket 3 installed with the gas stove 1 can effectively form a stable assembly for the control valve 4, and the control shaft 5 on the control valve 4 can be effectively adjusted to rotate eccentrically by using the connecting rod 6 set by the knob 12, so as to adjust the hole on the control shaft 5 to be the same as the gas pipe 2 assembled with the control valve 4, thereby adjusting the air intake amount of the gas;

[0040] Embodiment 2: Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The technical solution shown, on the basis of the first embodiment, further discloses the spacing adjustment between the telescopic rod 7 assembled by the connecting rod 6 and the telescopic assembly 11, the specific contents of which are as follows:

[0041] A telescopic rod 7 is installed on the outer surface of the connecting rod 6 in the gap control mechanism, and the outer surface of the telescopic rod 7 is threadedly connected with a bevel gear 1 8, and the outer surface side of the bevel gear 1 8 is meshingly connected with a bevel gear 2 9, and the outer surface of the bevel gear 2 9 is nested and connected with a nesting bin 10, and a telescopic component 11 is installed on the outer surface of the nesting bin 10, and a knob 12 is rotatably connected to the upper surface of the telescopic component 11, and a positioning shaft 13 is nested and connected to the middle section of the inner surface of the bevel gear 2 9, and a screwdriver bit 14 is nested and connected to the outer surface of the positioning shaft 13, and the nesting bin 10 is provided with a limit locking mechanism to prevent self-rotation.

[0042] The telescopic rod 7 and the connecting rod 6 form an integrated structure, and the telescopic rod 7 forms a threaded rotation structure for meshing adjustment with the bevel gear 1 8 and the bevel gear 2 9, and the bevel gear 1 8 and the nesting bin 10 form a nested rotation structure. At the same time, the nesting bin 10 and the outer surface end of the telescopic component 11 are embedded in the installation, and the telescopic component 11 and the knob 12 form an eccentric rotation structure, and the bevel gear 2 9 forms a positioning structure with the nesting bin 10 through the positioning shaft 13.

[0043] A limiting assembly 15 is installed on the outer surface of the nesting bin 10 in the limiting snap-fit ​​mechanism, and a limiting block 16 is slidably connected to the inner surface of the limiting assembly 15 , and a return spring 17 is nested and connected between the limiting assembly 15 and the limiting block 16 .

[0044] The limiting assembly 15 is embedded and installed with the outer surface of the nesting bin 10 , and the limiting assembly 15 and the limiting block 16 form an elastic sliding structure through the return spring 17 , and the limiting block 16 and the positioning shaft 13 form a limiting engaging structure.

[0045] When in use, due to long-term use, the eccentricity between the control shaft 5 and the connecting rod 6, as well as the eccentricity between the telescopic component 11 and the knob 12, the connection between them is prone to gap, which is very likely to affect the stability of the rotation of the control shaft 5. Therefore, the special screwdriver bit 14 is connected to the positioning shaft 13 to rotate, and the distance between the telescopic component 11 and the telescopic rod 7 is controlled, so as to adjust the stability of the control shaft 5. When adjusting the telescopic, the limit block 16 is controlled to slide on the inner surface of the limit component 15 with one hand, and the return spring 17 is squeezed to contract, so as to effectively separate the limit block 16 from the positioning shaft 13, and through the positioning rotation of the positioning shaft 13, the bevel gear 2 9 is effectively controlled to rotate in the nesting bin 10, and the meshing drives the thread adjustment between the bevel gear 1 8 and the telescopic rod 7, and the telescopic rod 7 and the telescopic component 11 form a limited sliding to prevent the telescopic rod 7 from deflecting and avoid affecting the stability of the connecting rod 6, thereby controlling the gap between the devices and improving the stability of the energy-saving gas flow control device.

[0047] The connecting wire 18 is nested and connected to the inner surface of the gas stove 1, and a temperature detection head 19 is installed on the upper side of the outer surface of the connecting wire 18, and a worm 20 assembled with a motor is connected to the other side of the outer surface of the connecting wire 18, and the worm 20 is limited and rotated on the lower side of the inner surface of the gas stove 1, and at the same time, the outer surface of the worm 20 is meshed and connected with a turbine 21, and the outer surface of the turbine 21 is installed with a control shaft 5.

[0048] The connecting wire 18 and the gas stove 1 form a through structure, and the connecting wire 18 and the lower surface of the temperature detection head 19 are embedded and installed, and the gas stove 1 forms a meshing rotation structure with the turbine 21 and the control shaft 5 through the worm 20.

[0049] When in use, the connecting line 18 assembled through the gas stove 1 and the temperature detection head 19 connected thereto can effectively monitor the temperature. When the gas fire is extinguished, the temperature monitoring will continue to drop too fast and be lower than the combustion temperature of the smaller flame. Then, the data can be transmitted to the motor assembled with the worm 20 through the connecting line 18, and the worm 20 can be controlled to adjust the turbine 21 to drive the control shaft 5 to form a positioning rotation, and the gas stove 1 can be controlled to be turned off, thereby improving the stability during use.

[0050] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
