Description

Technical Field

[0001] This invention relates to a gas stove, and more specifically, to a gas stove valve body that mechanically adjusts the gas passage orifice diameter. Background Technology

[0002] Gas stoves are common household appliances that use piped gas or liquefied petroleum gas (LPG) as fuel. To adjust the gas output of a gas stove to meet the different heat requirements of cooking ingredients and cooking times, it is necessary to adjust the gas flow rate.

[0003] The main component for regulating gas output is the solenoid valve. Current gas stove valve bodies achieve gas orifice diameter changes by adding a solenoid valve to the gas path. The solenoid valve's opening and closing is controlled by electrical signals from electronic components, thereby controlling the gas orifice diameter and regulating the gas output. Furthermore, the valve stem rotation angle and gas orifice diameter changes in current gas stove valve bodies are controlled by two separate systems, resulting in a complex structure and inconvenient operation.

[0004] Other commonly used flow control valves are mostly ordinary plunger valves, which generally include a valve body and a valve core. The valve core has an air outlet, while the valve body has an air hole. During the rotation of the valve core, the air outlet will align with the air hole, thereby realizing air output. The different overlapping areas of the air outlet and the air hole result in differences in the air output.

[0005] For example, Chinese Patent Application No. 201511030969.4 discloses a gas rotary valve, which includes a valve body, a valve core, and a valve stem. The valve body has an inlet and an outlet, and a distribution chamber inside the valve body. The distribution chamber is located in the gas path of the inlet and divides the inlet into inner and outer sections. The inner section of the inlet meets the wall of the distribution chamber to form a distribution port. The distribution chamber has a distribution wheel inside, and the distribution wheel has distribution ports arranged corresponding to the distribution ports. The back of the distribution wheel is in close contact with the wall of the distribution chamber with the distribution ports. The valve stem passes through the distribution wheel, and the rotation of the valve stem drives the distribution wheel to rotate simultaneously. However, this flow regulating valve cannot achieve linear regulation, has a very small adjustable range, and most of the adjustment is ineffective. Furthermore, the firepower regulation is not precise enough.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a gas stove valve body that controls the movement of the gas path adjustment device through the valve stem assembly, thereby changing the relative position with the gas passage. The gas path orifice can be changed using only mechanical structure without the need for electronic components, thereby achieving the adjustment of the gas flow rate. Moreover, this can be achieved in a single valve body structure, with a large adjustable range, high accuracy, and the ability to achieve linear adjustment and multi-level firepower supply.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a gas stove valve body, comprising,

[0009] The valve seat has a gas passage.

[0010] A gas flow regulating device is installed on the gas passage to regulate the gas flow rate of the gas stove valve body.

[0011] The valve stem assembly is used to control the movement of the gas path regulating device and change its relative position with the gas passage.

[0012] Furthermore, multiple regulating holes of different diameters are sequentially spaced along the moving direction of the gas path regulating device, and the axial direction of the regulating holes is the same as the gas flow direction.

[0013] The orifice diameter varies and can be set as needed to meet different air flow requirements. It can achieve linear adjustment and multiple firepower levels, with a wide adjustable range.

[0014] The shape of the regulating hole can be cylindrical, conical, etc., and can be set according to requirements. It can also regulate the gas flow rate.

[0015] The axial direction of the regulating hole is the same as the gas flow direction, making the gas flow smoother.

[0016] Furthermore, the diameter of the regulating hole is less than or equal to the diameter of the gas passage.

[0017] The gas flow rate can be adjusted by adjusting the orifice size at the gas outlet of the gas passage. Different orifice sizes result in different gas flow rates.

[0018] Furthermore, the valve stem assembly includes a first valve stem and a second valve stem, which are slidably connected.

[0019] Furthermore, the first valve stem has a connecting portion at one end facing the second valve stem, and the connecting portion is a region with a reduced outer diameter.

[0020] The second valve stem has a connecting groove at one end facing the first valve stem, and the extending direction of the connecting groove is parallel to the axial direction of the second valve stem.

[0021] The outer diameter of the connecting part is adapted to the inner diameter of the connecting groove, and the connecting part and the connecting groove are fitted together.

[0022] Furthermore, the connecting part is provided with a limiting part that protrudes from the outer peripheral surface of the connecting part.

[0023] The outer peripheral wall of the second valve stem is provided with a limiting hole that communicates with the connecting groove.

[0024] The limiting part is inserted into the limiting hole and protrudes from the outer peripheral wall of the second valve stem.

[0025] The sliding connection between the first and second valve stems allows the limiting part to slide within the limiting hole, thereby achieving axial height variation.

[0026] Furthermore, the sliding allowance of the limiting part within the limiting hole is greater than or equal to the distance between the farthest adjusting holes on the air path adjusting device.

[0027] This structural design ensures that, within the sliding distance of the first valve stem relative to the second valve stem, each regulating orifice on the gas path regulating device has the opportunity to be located within the gas passage, thereby achieving the regulation of the outflow volume.

[0028] Preferably, the limiting hole is provided with a plurality of limiting protrusions along the axial direction corresponding to the adjusting hole, for the limiting part to slide and limit within the limiting hole.

[0029] This structural design facilitates control over the sliding distance and position of the first valve stem relative to the second valve stem, ensuring that each limiting protrusion has a corresponding adjusting hole located within the gas passage when it limits the first valve stem. Furthermore, based on the correspondence between the limiting protrusion and the adjusting hole, the size of the adjusting hole within the gas passage can be selectively controlled to achieve the desired gas flow rate adjustment.

[0030] Furthermore, the limiting part is provided with a through opening along the rotation direction of the connecting part, and the through opening extends to the edge of the limiting part in a direction away from the connecting part;

[0031] The top of the air path regulating device is provided with a connecting rod, one end of which extends to the through-hole of the limiting part;

[0032] The height of the through-hole along the axial direction of the connecting part is greater than the thickness of the connecting rod.

[0033] When the first valve stem is rotated, the limiting part rotates freely with the first valve stem, and the connecting rod can pass through the through hole of the limiting part. At this time, the adjustment hole at the very end of the gas path regulating device is located in the gas passage. When the limiting part rotates to the position where the through hole corresponds to the connecting rod, one end of the connecting rod is located in the through hole. By sliding the first valve stem relative to the second valve stem, the limiting part slides in the limiting hole, and the through hole abuts against the connecting rod. The connecting rod drives the gas path regulating device to slide in the mounting groove, changing the size of the adjustment hole in the gas passage, thereby adjusting the gas flow rate.

[0034] Preferably, the limiting part includes two limiting posts spaced apart along the axial direction of the connecting part, the axial direction of the limiting posts being parallel to the radial direction of the connecting part, and the interval between the two limiting posts being greater than the thickness of the connecting rod.

[0035] Furthermore, it also includes a limiting seat installed on the valve seat, the limiting seat having a mounting hole, and the second valve stem rotatably passing through the mounting hole.

[0036] The limit seat is used to fix the valve stem assembly so that it does not shake freely and affect its use.

[0037] Preferably, the limiting seat has a limiting groove, which communicates with the mounting hole and extends from the mounting hole to the edge of the limiting seat, and the connecting rod is engaged in the limiting groove.

[0038] The limiting groove is used to limit the connecting rod and keep it in a fixed position. This facilitates the accurate fit between the connecting rod and the through-hole and does not affect the sliding of the limiting part in the limiting hole.

[0039] Furthermore, the valve seat is provided with a mounting groove, and the gas path regulating device is slidably disposed in the mounting groove, intersecting with the gas passage.

[0040] Preferably, the gas path regulating device is arranged radially through the gas passage.

[0041] The position of the regulating hole located in the gas passage is changed by sliding the gas path regulating device in the mounting groove.

[0042] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0043] This invention provides a gas stove valve body that controls the movement of a gas path regulating device through a valve stem assembly, changing its relative position with the gas passage and adjusting the size of the regulating hole located in the gas passage. The gas path orifice can be changed using only a mechanical structure without the need for electronic components, thereby achieving the adjustment of the gas flow rate. This can be achieved in a single valve body structure.

[0044] The sliding connection between the first and second valve stems allows the limiting part to slide within the limiting hole, thereby achieving axial height variation.

[0045] The sliding allowance of the limiting part within the limiting hole is greater than or equal to the distance between the farthest adjusting holes on the gas path regulating device. This is to ensure that within the sliding distance of the first valve stem relative to the second valve stem, each adjusting hole on the gas path regulating device has the opportunity to be located within the gas passage, thereby achieving the regulation of the outflow volume.

[0046] The limiting hole is provided with multiple limiting protrusions along the axial direction, which are corresponding to the adjusting hole. These protrusions are used to limit the sliding movement of the limiting part within the limiting hole, which facilitates the control of the sliding distance and position of the first valve stem relative to the second valve stem. This ensures that when each limiting protrusion limits the first valve stem, a corresponding adjusting hole is located within the gas passage. Furthermore, based on the correspondence between the limiting protrusions and the adjusting hole, the size of the adjusting hole within the gas passage can be selectively controlled to achieve the required gas flow rate adjustment.

[0047] The limit seat is used to fix the valve stem assembly so that it does not shake freely and affect its use.

[0048] The limiting groove is used to limit the connecting rod and keep it in a fixed position. This facilitates the accurate fit between the connecting rod and the through-hole and does not affect the sliding of the limiting part in the limiting hole.

[0049] The present invention provides a gas stove valve body that achieves gas flow regulation through the cooperation of a gas path regulating device, a valve stem assembly, and a limiting seat. It features a large adjustable range, high accuracy, linear adjustment, multi-level firepower supply, and a simple and easy-to-operate structure.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

For example, they can refer to detachable connections, mechanical connections, or electrical connections; they can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0063] like Figures 1 to 6 As shown, the present invention provides a gas stove valve body, including a valve seat 1, on which a gas passage 2, a mounting groove 3, a valve core 19, and a mounting plate 20 are provided; the gas passage 2 has an inlet 17 and an outlet 16; a gas path regulating device 4 is installed in the mounting groove 3, the gas path regulating device 4 has multiple regulating holes, and a connecting rod 15 is provided at the top; it also includes a valve stem assembly, which consists of a first valve stem 7 and a second valve stem 10; the first valve stem 7 has a connecting part 8, and the connecting part 8 has a limiting part 9; the second valve stem 10 has a connecting groove and a limiting hole 11, as well as a lever 18; it also includes a limiting seat 12, which is installed on the mounting plate 20 above the valve seat 1, and the limiting seat 12 has a mounting hole 13 and a limiting groove 14.

[0064] As one implementation method, such as Figures 1 to 6 As shown, the present invention provides a gas stove valve body, including a valve seat 1, a gas path regulating device 4, and a valve stem assembly.

[0065] like Figure 1 and Figure 2 As shown, the valve seat 1 is provided with a gas passage 2, which has an inlet 17 and an outlet 16. The arrow indicates the direction of gas flow 21.

[0066] The gas flow regulating device 4 is installed on the gas passage 2 and is used to regulate the gas flow rate of the gas stove valve body.

[0067] The valve stem assembly is used to control the movement of the gas path regulating device 4 and change its relative position with the gas passage 2.

[0068] Furthermore, multiple adjustment holes of different diameters are sequentially spaced along the moving direction of the gas path adjustment device 4, and the axial direction of the adjustment holes is the same as the gas flow direction 21.

[0069] The orifice diameter varies and can be set as needed to meet different air flow requirements. It can achieve linear adjustment and multiple firepower levels, with a wide adjustable range.

[0070] The shape of the regulating hole can be cylindrical, conical, etc., and can be set according to requirements. It can also regulate the gas flow rate.

[0071] The axial direction of the regulating hole is the same as the gas flow direction, making the gas flow smoother.

[0072] The diameter of the regulating hole is less than or equal to the diameter of the gas passage 2.

[0073] The gas flow rate can be adjusted by adjusting the orifice size at the gas outlet 16 of the gas passage 2. Different orifice sizes result in different gas flow rates at the gas outlet 16.

[0074] For example, such as Figure 1 and Figure 2 As shown, the air path regulating device 4 is provided with a first regulating hole 5 and a second regulating hole 6 with different apertures.

[0075] Furthermore, the valve seat 1 is provided with an installation groove 3, and the gas path regulating device 4 is slidably installed in the installation groove 3, intersecting with the gas passage 2.

[0076] The gas path regulating device 4 is installed radially through the gas passage 2.

[0077] The position of the regulating hole located in the gas passage 2 is changed by sliding the gas passage regulating device 4 in the mounting groove 3.

[0078] like Figures 1 to 5 As shown, the valve stem assembly includes a first valve stem 7 and a second valve stem 10, which are slidably connected.

[0079] The lower end of the first valve stem 7 is provided with a connecting part 8, which is a region with a reduced outer diameter.

[0080] The upper end of the second valve stem 10 is provided with a connecting groove, and the extending direction of the connecting groove is parallel to the axial direction of the second valve stem 10.

[0081] The outer diameter of the connecting part 8 is adapted to the inner diameter of the connecting groove, and the connecting part 8 and the connecting groove are fitted together.

[0082] The lower end of the connecting part 8 is provided with a limiting part 9 that protrudes from the outer peripheral surface of the connecting part 8.

[0083] The outer peripheral wall of the second valve stem 10 is provided with a limiting hole 11 that communicates with the connecting groove.

[0084] The limiting part 9 is inserted into the limiting hole 11 and protrudes from the outer peripheral wall of the second valve stem 10.

[0085] The sliding connection between the first valve stem 7 and the second valve stem 10 allows the limiting part 9 to slide within the limiting hole 11, thereby achieving axial height variation.

[0086] The sliding allowance of the limiting part 9 within the limiting hole 11 is greater than or equal to the distance between the farthest adjusting holes on the air path adjusting device 4.

[0087] This structural design is intended to ensure that, within the sliding distance of the first valve stem 7 relative to the second valve stem 10, each regulating hole on the gas path regulating device 4 has the opportunity to be located within the gas passage 2, thereby achieving the regulation of the outflow volume.

[0088] The limiting hole 11 is provided with a plurality of limiting protrusions along the axial direction, which correspond to the adjusting hole, for the limiting part 9 to slide and limit within the limiting hole 11.

[0089] This structural design facilitates the control of the sliding distance and position of the first valve stem 7 relative to the second valve stem 10, ensuring that each limiting protrusion has a corresponding adjusting hole located within the gas passage 2 when it limits the first valve stem 7. Furthermore, based on the correspondence between the limiting protrusion and the adjusting hole, the size of the adjusting hole within the gas passage 2 can be selectively controlled to achieve the required gas flow rate adjustment.

[0090] The limiting part 9 has a through opening along the rotation direction of the connecting part 8, and the through opening extends away from the connecting part 8 to the edge of the limiting part 9.

[0091] The top of the air path regulating device 4 is provided with a connecting rod 15, one end of which extends to the through-hole of the limiting part 9.

[0092] The height of the through-hole along the connecting part 8 in the axial direction is greater than the thickness of the connecting rod 15.

[0093] When the first valve stem 7 is rotated, the limiting part 9 rotates freely with the first valve stem 7, and the connecting rod 15 can pass through the through hole of the limiting part 9. At this time, the adjustment hole at the very end of the gas path regulating device 4 is located in the gas passage 2. When the limiting part 9 rotates to the position where the through hole corresponds to the connecting rod 15, one end of the connecting rod 15 is located in the through hole. The first valve stem 7 slides relative to the second valve stem 10, and the limiting part 9 slides in the limiting hole 11. The through hole abuts against the connecting rod 15, and the connecting rod 15 drives the gas path regulating device 4 to slide in the mounting groove 3, changing the size of the adjustment hole in the gas passage 2, thereby adjusting the gas flow rate.

[0094] like Figures 1 to 4 As shown, the limiting part 9 includes two limiting posts spaced apart along the axial direction of the connecting part 8. The axial direction of the limiting posts is parallel to the radial direction of the connecting part 8, and the interval between the two limiting posts is greater than the thickness of the connecting rod 15.

[0095] The limiting part 9 and the limiting hole 11 can also be arranged circumferentially.

[0096] Furthermore, it also includes a limiting seat 12 installed on the valve seat 1, the limiting seat 12 having a mounting hole 13, and the second valve stem 10 rotatably passing through the mounting hole 13.

[0097] The limit seat 12 is used to fix the valve stem assembly so that it does not shake freely and affect its use.

[0098] like Figure 1 , Figure 2 and Figure 6 As shown, a limiting groove 14 is provided on the limiting seat 12. The limiting groove 14 is connected to the mounting hole 13 and extends from the mounting hole 13 to the edge of the limiting seat 12. The connecting rod 15 is engaged in the limiting groove 14.

[0099] The limiting groove 14 is used to limit the connecting rod 15 and keep it in a fixed position, which is conducive to the accurate matching of the connecting rod 15 and the through hole, and will not affect the sliding of the limiting part 9 in the limiting hole 11.

[0100] like Figure 1 and Figure 2 As shown, valve core 19 is also provided inside valve seat 1, and vents of varying widths are provided on valve core 19.

[0101] The upper surface of the valve seat 1 is provided with a mounting plate 20. The mounting plate 20 is provided with a hole for the air supply regulating device 4 to extend and for the lower end of the second valve stem 10 to be inserted, and the second valve stem 10 can rotate in the hole.

[0102] A small hole is provided at the bottom of the mounting slot 3 to balance the air pressure in the mounting slot 3, so that the air path regulating device 4 can slide smoothly in the mounting slot 3.

[0103] The mounting slot 3 can also be open at the bottom. A limiting device is provided at the bottom of the mounting slot 3 to limit the air circuit regulating device 4 so that it will not come out from under the mounting slot 3.

[0104] A sealing ring can also be installed between the sliding interface of the mounting groove 3 and the gas path regulating device 4 to prevent gas leakage and ensure safety.

[0105] The upper part of the air path regulating device 4 has a region with a reduced outer diameter. The outer diameter of this region is adapted to the size of the corresponding hole on the mounting plate 20, so that the air path regulating device 4 can slide in the mounting groove 3 and extend out of the valve seat 1. The step generated by the reduced outer diameter region can limit the air path regulating device 4 and prevent it from falling out of the mounting groove 3 when it slides upward.

[0106] Meanwhile, the height of the area with a reduced outer diameter above the gas path regulating device 4 is less than or equal to the sliding allowance of the limiting part 9 within the limiting hole 11, and greater than or equal to the distance between the farthest regulating holes on the gas path regulating device 4. This allows the first valve stem 7 to slide relative to the second valve stem 10 a certain distance, satisfying the movement of the gas path regulating device 4 within the mounting groove 3, ensuring that each regulating hole has the opportunity to be located within the gas passage 2.

[0107] like Figures 1 to 4 As shown, the lower end of the second valve stem 10 is provided with a lever 18, which is located at the lower end of the mounting plate 20.

[0108] A limiting device is provided above the valve core 19, which is used to cooperate with the lever 18 for installation, so that the lever 18 can drive the valve core 19 to rotate.

[0109] The limiting part 9 and the lever 18 can be on the same axis as the valve stem assembly, or they can have any included angle.

[0110] like Figure 1 , Figure 2 and Figure 6 As shown, the limiting seat 12 is a structure formed by a rectangular plate with mounting holes 13 extending downward and outward from the corresponding sides of the rectangular plate.

[0111] The mounting hole 13 of the limiting seat 12 extends downward from the edge to form a circumferential limiting arm. The height of the limiting arm is less than the height of the limiting seat 12, and it has a limiting groove 14, which is mainly used to reinforce the valve stem assembly and prevent it from shaking randomly. Insecure installation will affect its use.

[0112] The limiting seat 12 can also have other structures and shapes, as long as it can fix the valve stem assembly and the connecting rod 15 without affecting the sliding of the first valve stem 7 relative to the second valve stem 10.

[0113] In this embodiment, when the valve stem assembly is in Figure 1 In the current state, the limiting part 9 on the first valve stem 7 is located below the limiting arm and is not embedded in the limiting groove 14 of the limiting seat 12. Therefore, the first valve stem 7 can drive the second valve stem 10 to rotate freely. The limiting part 9 rotates freely with the first valve stem 7, and the lever 18 rotates with the second valve stem 10 and drives the valve core 19 to rotate. Through the cooperation between the vent on the valve core 19 and the gas passage 2, the gas flow rate in the gas passage 2 can be adjusted. At this time, the first adjusting hole 5 is located in the gas passage 2 and is in the open state, while the second adjusting hole 6 is closed.

[0114] like Figure 2 As shown, when the first valve stem 7 is rotated to a suitable angle, the limiting part 9 rotates and corresponds to the position of the limiting groove 14. The connecting rod 15 abuts against the through hole of the limiting part 9. At this time, the first valve stem 7 is lifted up, and the limiting part 9 slides upward in the limiting hole 11 and the limiting groove 14, which will drive the connecting rod 15 to rise, thereby driving the gas path regulating device 4 to rise. At this time, the rise of the gas path regulating device 4 causes the first regulating hole 5 to leave the gas passage 2, and at the same time, the second regulating hole 6 rises into the gas passage 2. At this time, the first regulating hole 5 is closed and the second regulating hole 6 is open, realizing the regulation of the gas flow rate.

[0115] When in Figure 2 In this state, because the limiting part 9 on the first valve stem 7 is embedded in the limiting groove 14 of the limiting seat 12, the first valve stem 7 cannot rotate. It can only be restored to its original state by pressing the first valve stem 7 downwards. Figure 1 Rotation can only be performed when the state is in which the rotation occurs.

[0116] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
