Description

Technical Field

[0001] This application relates to the field of stove technology, and more particularly to a knob and gas stove. Background Technology

[0002] Gas stoves typically have a knob installed on the valve stem of the gas valve. When the user operates the knob, the valve stem can be moved to adjust the flame intensity and other functions.

[0003] Currently, the knob includes a knob body and a patch covering the knob body. A mounting hole is located in the center of the knob body, penetrating through it. The end of the valve stem extends into the mounting hole and abuts against the patch. When the user rotates or presses the knob body, it causes the valve stem to move synchronously with the knob body.

[0004] However, when the user presses the knob, the patch is subjected to an upward force from the end of the valve stem, and the patch is prone to falling off during long-term use. Utility Model Content

[0005] Based on this, this application provides a knob and a gas stove to solve the problem that the knob's patch is prone to falling off during long-term use in related technologies.

[0006] In a first aspect, embodiments of this application provide a knob, including:

[0007] The knob body has a cylindrical part in the middle, and the inner wall of the cylindrical part defines a first mounting hole and a second mounting hole that are interconnected. The first mounting hole is configured to allow the valve stem to extend into it.

[0008] A patch is installed on one end of the knob body;

[0009] The spring includes a first limiting section and a pressing section. One end of the first limiting section is connected to one end of the pressing section. Both the pressing section and the end of the first limiting section connected to the pressing section pass through a second mounting hole. The end of the first limiting section away from the pressing section extends into the first mounting hole. The first limiting section is configured to abut against the end of the valve stem. The middle part of the pressing section protrudes towards the first mounting hole. The middle part of the pressing section is configured to abut against the side wall of the valve stem.

[0010] Along the axial direction of the knob body, there is a gap between the patch and the first limiting segment.

[0011] In one possible implementation, the spring further includes a second limiting segment, one end of which is connected to the end of the compression segment away from the first limiting segment. The second limiting segment extends in a direction away from the first limiting segment and abuts against the end of the cylindrical portion.

[0012] In one possible implementation, the angle between the extrusion section and the first limiting section is less than 90 degrees.

[0013] In one possible implementation, the first limiting segment is inclined to the horizontal plane, and in a direction away from the extrusion segment, the first limiting segment is inclined in a direction away from the patch, and the end of the first limiting segment away from the extrusion segment abuts against the wall of the first mounting hole.

[0014] In one possible implementation, the wall of the first mounting hole on the side away from the second mounting hole is an abutment wall, the shape of the end of the first limiting segment away from the extrusion segment is consistent with the shape of the abutment wall, and the end of the first limiting segment away from the extrusion segment abuts against the abutment wall.

[0015] In one possible implementation, the edge of the second limiting segment at the end away from the extrusion segment extends beyond the outer wall of the cylindrical section.

[0016] In one possible implementation, the inner wall of the cylindrical part is provided with two limiting parts, which are located between the first mounting hole and the second mounting hole and are arranged opposite to each other.

[0017] The width of the extrusion section is greater than the width of the first limiting section. The side of the limiting part facing the second mounting hole is configured to abut against the limiting part. The first limiting section passes through the gap between the two limiting parts.

[0018] In one possible implementation, the width of the limiting portion gradually decreases along the direction away from the inner wall of the cylindrical portion.

[0019] In one possible implementation, the knob body also includes an annular wall and multiple connecting ribs;

[0020] The annular wall is wrapped around the outside of the cylindrical part, and the two ends of each connecting rib are connected to the outer wall of the cylindrical part and the inner wall of the annular wall, respectively. Multiple connecting ribs are arranged at intervals around the axis of the annular wall.

[0021] Secondly, this application provides a gas stove, including a gas valve and the aforementioned knob, wherein the gas valve is provided with a valve stem, the end of which extends into the first mounting hole of the knob;

[0022] The first limiting section of the spring abuts against the end of the valve stem, and the pressing section of the spring presses against the side wall of the valve stem.

[0023] The knob and gas stove provided in this application include a knob body, a patch, and a spring. The knob body has a cylindrical portion in its center, with a first mounting hole and a second mounting hole communicating with each other inside. The spring includes a first limiting section and a pressing section connected in sequence, with the pressing section and the end of the first limiting section connected to the pressing section both penetrating into the second mounting hole. When the valve stem is inserted into the first mounting hole of the knob body, the first limiting section of the spring abuts against the end of the valve stem, and there is a gap between the first limiting section and the patch to limit the depth of the valve stem insertion into the first mounting hole. The pressing section of the spring abuts against the side wall of the valve stem, thereby making the connection between the valve stem and the knob body tighter, preventing the knob from shifting relative to the valve stem. This ensures a tight connection between the knob and the valve stem while preventing the valve stem from abutting against the patch on the knob, thus preventing the patch from detaching.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0041] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0042] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0043] In existing technology, a knob includes a knob body and a patch covering the knob body. A mounting hole penetrating the knob body is provided in the middle, and the end of a valve stem extends into the mounting hole and abuts against the patch. When the user rotates or presses the knob body, it causes the valve stem to move synchronously with the knob body. However, when the user presses the knob, the patch is subjected to an upward force from the end of the valve stem, and the patch is prone to detaching during long-term use. Currently, one type of knob incorporates a limit block internally to limit the engagement height between the valve stem and the knob. However, the limit block increases the cost of the knob and also increases the difficulty of its manufacturing.

[0044] After repeated consideration and verification, the inventors discovered that knobs typically contain a spring plate, which presses against the side wall of the valve stem to ensure a tight fit between the knob and the valve stem. If a limiting structure is added to the spring plate, when one end of the valve stem extends into the knob, the limiting structure on the spring plate abuts against the end of the valve stem, thus limiting the depth to which the valve stem can penetrate the knob. The spacing between the limiting structure of the spring plate and the knob's contact patch prevents the end of the valve stem from directly abutting against the knob's contact patch, thus ensuring a tight fit between the valve stem and the knob while preventing the contact patch from detaching. Furthermore, compared to adding a limiting block to the knob, this method is less expensive and does not increase the difficulty of manufacturing the knob.

[0045] In view of this, the inventor designed a knob and a gas stove. The knob has a cylindrical portion in the middle of its body, with a first mounting hole and a second mounting hole communicating with each other within the cylindrical portion. The spring includes a first limiting section and a pressing section. The pressing section and the end of the first limiting section connected to the pressing section both pass through the second mounting hole. The end of the first limiting section away from the pressing section extends into the first mounting hole. The pressing section abuts against the side wall of the valve stem to ensure a tight connection between the valve stem and the knob body. The first limiting section abuts against the end of the valve stem in the first mounting hole to limit the depth of the valve stem extending into the knob body. A gap is provided between the first limiting section and the knob's contact patch to prevent the end of the valve stem from abutting against the patch. This ensures a tight fit between the valve stem and the knob while preventing the contact patch on the knob from falling off.

[0046] The technical solutions of the knob and gas stove provided in the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0047] Reference Figures 1 to 6As shown, the knob provided in this embodiment includes a knob body 100, a patch 300, and a spring 200. A cylindrical portion 110 is provided in the middle of the knob body 100. The inner wall of the cylindrical portion 110 defines a first mounting hole 111 and a second mounting hole 112 that communicate with each other. The first mounting hole 111 is configured to allow a valve stem 201 to extend into it. Schematably, the axis of the cylindrical portion 110 can be located on the rotation axis of the knob body 100. The first mounting hole 111 and the second mounting hole 112 are arranged laterally side-by-side, and can be integrally formed within the cylindrical portion 110. The cross-sectional shape and size of the first mounting hole 111 match the valve stem 201, so that the valve stem 201 can rotate when the user rotates the knob body 100.

[0048] A patch 300 is mounted on one end of the knob body 100. The patch 300 is a sheet-like structure, its shape and size matching the knob body 100. For example, adhesive is provided on the side of the patch 300 facing the knob body 100, and it is bonded and fixed to the knob body 100 by the adhesive. Figure 2 and Figure 6 As shown, the patch 300 is provided with an indicator mark 310. The user can determine the firepower of the gas stove by using the indicator mark 310, which makes it easier for the user to adjust the firepower and turn the gas stove on and off.

[0049] The spring sheet 200 includes a first limiting segment 210 and a pressing segment 220, with one end of the first limiting segment 210 connected to one end of the pressing segment 220. It is understood that both the first limiting segment 210 and the pressing segment 220 are sheet-like structures, and are connected sequentially. Those skilled in the art can form the spring sheet 200 by bending a metal sheet. The material of the spring sheet 200 has good toughness, fatigue strength, and a high elastic limit; for example, the spring sheet 200 can be made of carbon spring steel or alloy spring steel.

[0050] The ends of the compression section 220 and the first limiting section 210 connected to the compression section 220 both pass through the second mounting hole 112, while the end of the first limiting section 210 away from the compression section 220 extends into the first mounting hole 111. The second mounting hole 112 can limit the compression section 220, preventing the spring piece 200 from moving relative to the knob body 100.

[0051] The first limiting section 210 is configured to abut against the end of the valve stem 201, and the middle part of the pressing section 220 protrudes toward the first mounting hole 111, and the middle part of the pressing section 220 is configured to abut against the side wall of the valve stem 201.

[0052] Understandably, once the depth of the compression section 220 extending into the second mounting hole 112 is determined, the portion of the first limiting section 210 extending from the second mounting hole 112 into the first mounting hole 111 abuts against the end of the valve stem 201, thus limiting the depth of the valve stem 201 extending into the knob body 100 and preventing it from extending too deeply. A portion of the sidewall of the valve stem 201 can extend from the first mounting hole 111 into the second mounting hole 112 and press against the middle of the compression section 220. The elasticity of the compression section 220 ensures a tight fit between the valve stem 201 and the knob body 100. When the user presses or rotates the knob body 100, the valve stem 201 will not move relative to the knob body 100, ensuring consistency between the knob and the valve stem 201 and the feel of the knob.

[0053] In one possible implementation, such as Figure 1 , Figure 2 and Figure 5 As shown, the compression section 220 can be arc-shaped, with the middle portion extending towards the first mounting hole 111. When one end of the valve stem 201 extends into the first mounting hole 111, the middle portion of the compression section 220 can compress the sidewall of the valve stem 201. In another possible implementation, the compression section 220 includes a first connecting section and a second connecting section connected to each other, with the extension directions of the first connecting section and the second connecting section inclined to each other. This creates a protruding angle in the middle portion of the compression section 220, which can also compress the sidewall of the valve stem 201.

[0054] Along the axial direction of the knob body 100, there is a gap between the patch 300 and the first limiting segment 210. It is understood that the gap between the patch 300 and the first limiting segment 210 prevents the valve stem 201 from pushing against the patch 300 of the knob after it extends into the first mounting hole 111, thereby preventing the patch 300 from falling off. Those skilled in the art can set the specific size of the gap between the patch 300 and the first limiting segment 210 as needed; no single limitation is made here.

[0055] In this embodiment, when the valve stem 201 is inserted into the first mounting hole 111 of the knob body 100, the first limiting section 210 of the spring piece 200 abuts against the end of the valve stem 201, and there is a gap between the first limiting section 210 and the patch 300 to limit the depth of the valve stem 201 into the first mounting hole 111. The pressing section 220 of the spring piece 200 abuts against the side wall of the valve stem 201, thereby making the connection between the valve stem 201 and the knob body 100 tighter, so that the knob will not move relative to the valve stem 201. In this way, while ensuring a tight connection between the knob and the valve stem 201, the valve stem 201 is prevented from abutting against the patch 300 on the knob, and the patch 300 on the knob is prevented from falling off.

[0056] In addition, compared to setting limit blocks in knobs, knobs are less expensive and do not increase the difficulty of manufacturing knobs.

[0057] In one embodiment, such as Figures 1-5 As shown, the spring 200 also includes a second limiting section 230. One end of the second limiting section 230 is connected to the end of the compression section 220 away from the first limiting section 210. The second limiting section 230 extends in a direction away from the first limiting section 210 and abuts against the end of the cylindrical portion 110.

[0058] The second limiting segment 230 is also a sheet-like structure. Its shape can be rectangular or semi-circular, or other suitable shapes. The first limiting segment 210, the pressing segment 220, and the second limiting segment 230 are connected sequentially, defining an approximate "Z"-shaped structure. Understandably, during the assembly process, after the pressing segment 220 of the spring piece 200 is inserted into the second mounting hole 112, when the second limiting segment 230 abuts against the end of the cylindrical portion 110, it indicates that the spring piece 200 is properly assembled, ensuring the depth of the pressing segment 220 into the second mounting hole 112. At this time, the first limiting segment 210 and the patch 300 are spaced apart axially in the knob body 100. The first limiting segment 210 reliably limits the depth of the valve stem 201 inserted into the first mounting hole 111.

[0059] This structure, through the cooperation between the second limiting section 230 and the cylindrical part 110, can limit the position of the spring piece 200, prevent the extrusion section 220 from extending too deep into the second mounting hole 112, and prevent the valve stem 201 from pushing the first limiting section 210 to abut against the patch 300, so as to reliably prevent the patch 300 on the knob from falling off.

[0060] In other embodiments, the depth of the second mounting hole 112 may be less than the depth of the first mounting hole 111. For example, the first mounting hole 111 may be configured as a through hole and the second mounting hole 112 as a blind hole. After the pressing section 220 of the spring piece 200 extends into the second mounting hole 112, the end of the pressing section 220 facing the patch 300 abuts against the end of the second mounting hole 112 facing the patch 300. The spring piece 200 is limited by the cooperation between the spring piece 200 and the second mounting hole 112, so as to prevent the valve stem 201 from pushing the first limiting section 210 to abut against the patch 300, thereby reliably preventing the patch 300 on the knob from falling off.

[0061] In one embodiment, the angle between the compression section 220 and the first limiting section 210 is less than 90 degrees.

[0062] Schematic illustration: When the extrusion section 220 is an arc-shaped sheet structure and the first limiting section 210 is a planar extending sheet structure, the included angle between the extrusion section 220 and the first limiting section 210 is the angle between the normal to the end connecting the extrusion section 220 and the first limiting section 210 and the first limiting section 210. It is understood that the angle between the extrusion section 220 and the first limiting section 210 is an acute angle. In this embodiment, the specific size of the included angle between the extrusion section 220 and the first limiting section 210 is not limited; those skilled in the art can impose limitations as needed.

[0063] During the assembly process of the knob and valve stem 201, after the end of the valve stem 201 pushes against the first limiting section 210, the included angle between the first limiting section 210 and the pressing section 220 increases. The first limiting section 210 drives the pressure between the pressing section 220 and the side wall of the valve stem 201 to increase, which further increases the tightness of the connection between the valve stem 201 and the knob body 100, and further improves the consistency between the knob and the valve stem 201 and the feel of the knob.

[0064] like Figure 1 and Figure 2 As shown, the first limiting segment 210 is inclined to the horizontal plane. Along the direction away from the extrusion segment 220, the first limiting segment 210 is inclined in the direction away from the patch 300. The end of the first limiting segment 210 away from the extrusion segment 220 abuts against the wall of the first mounting hole 111.

[0065] Understandably, when the knob is in use, the height of the end of the first limiting section 210 facing the pressing section 220 is higher than the height of the end of the first limiting section 210 away from the pressing section 220. During the assembly process of the knob and the valve stem 201, the end of the valve stem 201 pushes against the first limiting section 210, increasing the angle between the first limiting section 210 and the pressing section 220, causing the end of the first limiting section 210 away from the pressing section 220 to abut against the wall of the first mounting hole 111.

[0066] This structure, when the knob is pulled upwards and the valve stem 201 is disengaged from the knob body 100, increases the resistance between the spring piece 200 and the cylindrical part 110 through the cooperation between the first limiting section 210 and the hole wall of the first mounting hole 111, preventing the spring piece 200 from falling off, which helps to ensure the service life of the knob.

[0067] like Figures 2-5 As shown, the wall of the first mounting hole 111 on the side away from the second mounting hole 112 is the abutment wall 1111. The shape of the end of the first limiting segment 210 away from the extrusion segment 220 is consistent with the shape of the abutment wall 1111. The end of the first limiting segment 210 away from the extrusion segment 220 abuts against the abutment wall 1111.

[0068] Schematic illustration: when the first limiting segment 210 is rectangular, the abutment wall 1111 is a plane matching the first limiting segment 210; when the first limiting segment 210 is semi-circular, the abutment wall 1111 is an arc surface matching the end of the first limiting segment 210 away from the extrusion segment 220. This arrangement ensures that the end of the first limiting segment 210 away from the extrusion segment 220 abuts tightly against the abutment wall 1111.

[0069] The cooperation between the abutment wall 1111 and the first limiting section 210 ensures the contact area between the hole wall of the first mounting hole 111 and the first limiting section 210, and ensures the friction between the hole wall of the first mounting hole 111 and the first limiting section 210. When the knob is pulled up so that the valve stem 201 is disengaged from the knob body 100, the spring piece 200 can be reliably prevented from falling off.

[0070] like Figure 2 and Figure 3 As shown, the edge of the second limiting section 230 at the end away from the extrusion section 220 extends beyond the outer wall of the cylindrical section 110.

[0071] Schematic illustration: the second limiting segment 230 is rectangular in shape, and the corner of the second limiting segment 230 away from the extrusion segment 220 extends beyond the outer wall of the cylindrical portion 110. Those skilled in the art can set the size of the second limiting segment 230 extending beyond the cylindrical portion 110 as needed, and no unique limitation is made here.

[0072] When it is necessary to remove the spring piece 200 on the knob body 100, the spring piece 200 can be pulled out from the knob body 100 by holding the part of the second limiting section 230 that extends beyond the cylindrical part 110. The above-mentioned arrangement facilitates the removal of the spring piece 200, thereby facilitating the maintenance of the knob.

[0073] In one embodiment, such as Figures 2-4 As shown, the inner wall of the cylindrical portion 110 is provided with two limiting portions 113, which are located between and opposite to the first mounting hole 111 and the second mounting hole 112. The first mounting hole 111 and the second mounting hole 112 are connected by a gap between the two limiting portions 113. The maximum width of both the first mounting hole 111 and the maximum width of the second mounting hole 112 are greater than the gap width between the two limiting portions 113. The two limiting portions 113 can be integrally formed onto the inner wall of the cylindrical portion 110.

[0074] The width of the extrusion section 220 is greater than the width of the first limiting section 210. The side of the limiting part 113 facing the second mounting hole 112 is configured to abut against the limiting part 113. The first limiting section 210 passes through the gap between the two limiting parts 113.

[0075] Schematic, the width of the second mounting hole 112 matches the width of the extrusion section 220, and the width of the first limiting section 210 matches the spacing between the two limiting portions 113. The side of the limiting portion 113 away from the first mounting hole 111 can abut against the extrusion section 220.

[0076] With the above configuration, when the extrusion section 220 extends into the second mounting hole 112, the two limiting parts 113 can retain the extrusion section 220 in the second mounting hole 112. The cooperation between the second mounting hole 112 and the extrusion section 220 can reliably limit the spring piece 200, so that the spring piece 200 will not move laterally relative to the knob body 100, ensuring that the first limiting section 210 and the extrusion section 220 of the spring piece 200 can reliably limit the valve stem 201.

[0077] In a specific embodiment, such as Figures 2-4 As shown, the width of the limiting part 113 gradually decreases along the direction away from the inner wall of the cylindrical part 110.

[0078] Indicatively, the limiting part 113 can be a columnar structure with a cross-sectional shape that is approximately triangular, and the apex of the triangle is set opposite to each other.

[0079] When one end of the valve stem 201 extends into the first mounting hole 111, part of the side wall of the valve stem 201 can easily pass over the limiting part 113 and extend into the second mounting hole 112, thereby enabling the pressing section 220 to reliably press the side wall of the valve stem 201.

[0080] like Figure 1 , Figure 2 and Figure 4 As shown, the knob body 100 also includes an annular wall 120 and a plurality of connecting ribs 130. The annular wall 120 is arranged around the outer side of the cylindrical part 110, and the two ends of each connecting rib 130 are respectively connected to the outer wall of the cylindrical part 110 and the inner wall of the annular wall 120. The plurality of connecting ribs 130 are spaced apart around the axis of the annular wall 120.

[0081] The annular wall 120 is a cylindrical structure surrounding the outer side of the cylindrical portion 110, and it can be coaxially arranged with the cylindrical portion 110. The patch 300 can be attached to one end of the annular wall 120 and the cylindrical portion 110. The connecting ribs 130 can be sheet-like structures, and there are at least two of them. Multiple connecting ribs 130 can be arranged at equal intervals around the axis of the cylindrical portion 110.

[0082] Schematic, the cylindrical portion 110, the annular wall 120, and the multiple connecting ribs 130 can be formed into a single piece using an integral molding process such as die casting or stretching. The knob body 100 can be made of suitable materials such as zinc alloy or aluminum alloy. Preferably, the knob body 100 can be formed using a stretching process, which offers higher material utilization and production efficiency compared to die casting. Furthermore, the surface of the stretched profile is relatively smooth with a more uniform texture, and subsequent surface treatment processes are easier, resulting in better surface quality and appearance.

[0083] In this structure, the annular wall 120 of the knob body 100 facilitates the user's rotation of the knob, and the multiple connecting ribs 130 between the annular wall 120 and the cylindrical part 110 ensure the structural strength of the knob body 100 and guarantee the service life of the knob.

[0084] This application also provides a gas stove, such as Figure 1 As shown, the gas stove includes a gas valve 20 and the aforementioned knob. The gas valve 20 is provided with a valve stem 201, the end of which extends into the first mounting hole 111 of the knob. The first limiting section 210 of the spring 200 abuts against the end of the valve stem 201, and the pressing section 220 of the spring 200 presses against the side wall of the valve stem 201.

[0085] Figure 1 As shown, the gas stove also includes a chassis 40 and a panel 30 covering the chassis 40. The chassis 40 has a cavity, which is sealed by the panel 30 after it is placed on the chassis 40. The valve body of the gas valve 20 is installed in the cavity of the chassis 40, and the top of the valve stem 201 of the gas valve 20 extends into the first mounting hole 111 of the knob.

[0086] The gas stove provided in this application uses the aforementioned knob, which ensures a tight connection between the valve stem 201 and the knob, and prevents the valve stem 201 from abutting against the patch 300 on the knob, thus avoiding the patch 300 from falling off and improving the user experience.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
