Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a gas valve and a gas stove. Background Technology

[0002] To meet user needs, some gas stoves are designed with a high-heat function. When the high-heat function is turned on, the gas stove's heat will increase instantly to meet the user's need for stir-frying.

[0003] Currently, gas stoves have gas valves with separate high-heat and conventional gas channels, which are connected to the stove's combustion system via corresponding pipes. The gas stove controls the connection between these two channels by rotating the valve stem. When the valve stem is turned to the high-heat setting, both channels are open, with some gas flowing to the combustion system via the high-heat channel and its corresponding pipe, and the other portion flowing via the conventional channel and its corresponding pipe.

[0004] However, when users adjust the gas valve to the high-power setting, backfire may occur in the combustion system, posing a certain safety hazard. Utility Model Content

[0005] Based on this, the present invention provides a gas valve and a gas stove to solve the problem that backfire may occur in the combustion system when the user adjusts the gas valve to the stir-fry setting in the related technology.

[0006] In a first aspect, embodiments of the present invention provide a gas valve, comprising:

[0007] The valve body has a gas passage for high-heat stir-frying;

[0008] The valve stem includes a stem body and a gear plate. The stem body is rotatably mounted on the valve body and has a high-heat flame hole. The gear plate is sleeved on the stem body and fixed to the stem body. The first side of the gear plate has a high-heat setting.

[0009] The positioning element has its first end connected to the valve body and its second end abutting against the first side of the gear shift disc.

[0010] When the second end of the positioning component is in the stir-fry setting, the stir-fry flame hole and the stir-fry flame gas passage are fully connected.

[0011] The stir-fry setting has first guide walls on opposite sides of the rod body along the circumference. The first guide walls are inclined in the thickness direction of the gear plate. Along the thickness of the gear plate away from the gear plate, the first guide walls gradually move away from the stir-fry setting to the middle of the rod body in the circumference direction.

[0012] In one possible implementation, a linear gear is also provided on the first side of the gear plate. The linear gear is an arc-shaped groove arranged around the axis of the rod body, and the stir-fry gear is located within the linear gear.

[0013] In one possible implementation, the bottom of the arc-shaped groove is provided with two protruding ribs, which are arranged at intervals along the circumference of the rod. The interval between the two ribs defines the stir-fry setting, and the opposite sides of the two ribs are two first guide walls.

[0014] In one possible implementation, a second guide wall is provided on each of the two opposing sides of the ribs, and the second guide wall is inclined in the thickness direction of the gear plate.

[0015] Along the thickness of the gear shift plate away from the bottom of the arc groove, the second guide wall gradually approaches the center of the linear gear in the circumferential direction of the rod.

[0016] In one possible implementation, a third guide wall is provided at the end of the arc groove along the circumferential direction of the rod body, and the third guide wall is inclined to the thickness direction of the gear plate.

[0017] Along the thickness of the gear shift plate away from the bottom of the arc groove, the third guide wall gradually moves away from the linear gear at the center of the rod body in the circumferential direction.

[0018] In one possible implementation, the stir-fry setting is a groove set at the bottom of the arc-shaped groove. The groove is arc-shaped and arranged around the axis of the rod body. The two first guide walls are the side walls on opposite sides of the groove rod body in the circumferential direction.

[0019] In one possible implementation, the stir-fry setting is located in the middle of the linear setting along the circumference of the rod.

[0020] In one possible implementation, the gas valve further includes a resilient element, one end of which is connected to the valve body and the other end of which is connected to a positioning element. The resilient element is configured to cause the positioning element to press against the gear plate.

[0021] In one possible implementation, the second end of the positioning element is an arc-shaped surface protruding towards the gear shift dial; or,

[0022] The second end of the positioning component is rotatably mounted with a top ball, which abuts against the first side of the gear shift plate.

[0023] Secondly, this utility model embodiment provides a gas stove, including a high-heat flame pipeline, a combustion system and the aforementioned gas valve, wherein the two ends of the high-heat flame pipeline are respectively connected to the combustion system and the high-heat flame gas passage of the gas valve.

[0024] This utility model provides a gas valve and a gas stove. The gas valve includes a valve body, a valve stem, and a positioning element. The valve stem includes a rod body and a position plate. The rod body is rotatably mounted on the valve body, and the position plate is sleeved on and fixed to the rod body. A high-power setting is provided on the first side of the position plate. The first end of the positioning element is connected to the valve body, and the second end of the positioning element abuts against the first side of the position plate. By determining whether the second end of the positioning element is located at the high-power setting on the position plate, it can be determined whether the gas valve has been adjusted to the high-power setting. First guide walls are respectively provided on opposite sides of the rod body along the circumference of the high-power setting. When the gas valve is adjusted from the normal setting to the high-power setting, the interaction between the first guide walls and the second end of the positioning element guides the valve stem, allowing the position plate on the valve stem to quickly rotate to the position where the high-power setting aligns with the second end of the positioning element, thus preventing backfire caused by insufficient load when switching the gas valve to the high-power setting. The two first guide walls can limit the second end of the positioning element, aligning the second end of the positioning element with the high-heat setting. This ensures that the high-heat flame hole on the valve stem is fully connected to the high-heat flame gas passage on the valve body, maximizing the flow of gas in the gas valve. This prevents backfire problems caused by insufficient gas flow in the gas stove's combustion system, thus improving the safety of the gas stove. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the present utility model will be described in more detail below with reference to the accompanying drawings of the preferred embodiments. 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, embodiments of this utility model. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly 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 of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing this utility model 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 utility model.

[0046] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0047] 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.

[0048] In existing technology, the gas valve of a gas stove has a high-heat (stir-fry) gas passage and a conventional gas passage, which are connected to the stove's combustion system via corresponding pipes. The gas stove controls the connection between these two passages by rotating the valve stem. When the valve stem is rotated to the high-heat setting, both passages are open, with some gas flowing to the combustion system via the high-heat passage and the conventional gas passage. However, when the user adjusts the gas valve to the high-heat setting, the high-heat gas passage may only be partially open due to insufficient valve stem rotation, resulting in insufficient gas flow for the high-heat setting. This could lead to backfire in the combustion system, posing a safety hazard to the gas valve.

[0049] After repeated consideration and verification, the inventors discovered that by installing a gear selector on the valve stem, setting gears on the gear selector, and installing a positioning component on the gas valve body, the gas valve's gear position can be determined through the cooperation between the positioning component and the gear selector. A "stir-fry" gear position is set on the gear selector for cooperation with the positioning component. When the second end of the positioning component is in the stir-fry gear position, the gas valve is in the stir-fry gear, at which point the gas valve's stir-fry flame gas passage is fully open. First guide walls are respectively provided on opposite sides of the stir-fry gear position along the circumference of the stem. When the first guide walls abut against the end of the positioning component, they guide the end of the positioning component into the stir-fry gear position. Through the cooperation between the first guide walls and the positioning component, the user can quickly switch the gas valve to the stir-fry gear without any partial opening of the stir-fry flame gas passage, preventing backfire in the gas valve's combustion system due to low gas flow and improving the gas valve's safety.

[0050] In view of this, the inventors designed a gas valve and a gas stove. The gas valve has a gear shift plate on the valve stem and a positioning element on the valve body that abuts against the gear shift plate. The gear shift plate has a high-power setting (like a stir-fry setting). First guide walls are respectively provided on opposite sides of the high-power setting along the circumference of the valve stem. The first guide walls guide and limit the end of the positioning element, allowing the end of the positioning element to move quickly relative to the gear shift plate into the high-power setting, and ensuring that the end of the positioning element is completely aligned with the high-power setting. This ensures the flow rate of gas used for stir-frying in the gas valve when in the high-power setting, preventing backfire in the combustion system due to insufficient gas flow for stir-frying.

[0051] The technical solutions of the gas valve and gas stove provided in the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0052] Reference Figures 1 to 8 As shown, the gas valve 10 provided in this embodiment of the present invention includes a valve body 100, a valve stem 200, and a positioning member 300. The valve body 100 has a high-heat gas passage 111. The valve stem 200 includes a stem body 210 and a gear plate 220. The stem body 210 is rotatably mounted on the valve body 100, and a high-heat hole 211 is provided on the stem body 210. The gear plate 220 is sleeved on the stem body 210 and fixed to the stem body 210. A high-heat gear 221 is provided on the first side of the gear plate 220.

[0053] When the rod 210 rotates relative to the valve body 100, it can drive the gear plate 220 to rotate synchronously. After the gear plate 220 is sleeved on the rod 210, it can be fixed by welding or key connection. Schematic, the gear plate 220 is a plate-like structure, and the extension direction of the plate-like structure is perpendicular to the axial direction of the rod 210.

[0054] The first end of the positioning member 300 is connected to the valve body 100, and the second end of the positioning member 300 abuts against the first side of the gear shift disc 220. The positioning member 300 is located between the first side of the gear shift disc 220 and the valve body 100. Notably, the second end of the positioning member 300 can press against the gear shift disc 220. The gear position of the gas valve 10 can be determined based on the relative position between the positioning member 300 and the gear shift disc 220. In one possible implementation, the positioning member 300 can be a strip-shaped structure, with one end connected to the valve body 100 and the other end abutting against the first side of the gear shift disc 220.

[0055] When the second end of the positioning member 300 is in the high-heat setting 221, the high-heat flame hole 211 is fully connected to the high-heat gas passage 111. For example, when the second end of the positioning member 300 is in the high-heat setting 221, the valve stem 200 rotates 90° relative to the valve body 100. At this time, the high-heat flame hole 211 on the stem 210 is connected to the high-heat gas passage 111, and the connection area is at its maximum. Figure 4 and Figure 5 As shown, the additional gas required for stir-frying can flow through the stir-frying port 211 and the stir-frying gas passage 111 in the direction indicated by the arrow, and be output to the gas valve 10.

[0056] Schematic, the valve body 100 includes a valve body 110 and a valve cover 120 mounted on the valve body 110. The valve body 110 has a frying gas passage 111. A rod 210 passes through the valve cover 120 and is rotatably connected to it. The end of the rod 210 extends into the valve body 110. A gear shift disc 220 is located between the valve body 110 and the valve cover 120. The frying gas hole 211 on the rod 210 is located on the portion of the rod 210 that extends into the valve body 110. The end of the rod 210 away from the valve body 110 can protrude from the valve cover 120, and a knob can be installed on the end of the rod 210 protruding from the valve cover 120 for user adjustment of the valve rod 200. A positioning element 300 is located on the side of the gear shift disc 220 away from the valve body 110, and the first side of the gear shift disc 220 is the side of the gear shift disc 220 away from the valve body 110.

[0057] The stir-fry gear position 221 has first guide walls 222 on opposite sides of the rod body 210 circumferentially upward. The first guide walls 222 are inclined in the thickness direction of the gear plate 220. Along the thickness of the gear plate 220 away from the gear plate 220, the first guide walls 222 gradually move away from the stir-fry gear position 221 to the middle of the rod body 210 circumferentially upward.

[0058] In one possible implementation, the first guide wall 222 can be an inclined surface tilted towards the extending direction of the gear shift disk 220. The inclination angle of the inclined surface can be set as needed and is not limited here. It can be understood that the gap between the two first guide walls 222 gradually increases along the thickness of the gear shift disk 220 away from the gear shift disk 220. When the second end of the positioning member 300 abuts against the first guide wall 222, due to the pressure of the second end of the positioning member 300 on the gear shift disk 220, under the action of the first guide wall 222, the gear shift disk 220 can quickly rotate to the position where the high-heat gear 221 is directly opposite the second end of the positioning member 300, so that the second end of the positioning member 300 is located in the high-heat gear 221.

[0059] In this embodiment, the gas valve 10, when adjusted from the normal setting to the high-heat setting, guides the valve stem 200 through the interaction between the first guide wall 222 and the second end of the positioning member 300. This allows the position plate 220 on the valve stem 200 to quickly rotate to the position where the high-heat setting 221 aligns with the second end of the positioning member 300, preventing backfire due to insufficient load when switching the gas valve 10 to the high-heat setting. The two first guide walls 222 also limit the second end of the positioning member 300, aligning it with the high-heat setting 221. This ensures complete communication between the high-heat flame hole 211 on the valve stem 200 and the high-heat flame gas passage 111 on the valve body 100, maximizing the flow rate of gas in the gas valve 10. This prevents backfire caused by insufficient gas flow in the gas stove's combustion system 30, improving the safety of the gas stove.

[0060] In one embodiment, such as Figure 2 , Figure 8 and Figure 9 As shown, a linear gear is also provided on the first side of the gear shift plate 220. The linear gear is an arc-shaped groove 223 arranged around the axis of the rod body 210, and the stir-fry gear 221 is located within the linear gear.

[0061] The linear and high-heat settings 221 are located on the same side of the setting plate 220. The orthographic projection of the high-heat setting 221 along the thickness direction of the setting plate 220 lies within the orthographic projection of the linear setting along the thickness direction of the setting plate 220. When the second end of the positioning member 300 abuts against the linear setting, the gas valve 10 is in the normal setting. The user can adjust the firepower of the gas stove by rotating the valve stem 200 to move the second end of the positioning member 300 in the linear setting. When the user rotates the valve stem 200, the second end of the positioning member 300 can move from the linear setting to the high-heat setting 221.

[0062] Understandably, when the second end of the positioning element 300 abuts against the linear gear position, the gas valve 10 can output gas. With the linear gear position set as an arc-shaped groove 223, when the user rotates the valve stem 200, causing the second end of the positioning element 300 to move from outside the linear gear position to inside, a sound will be emitted between the positioning element 300 and the gear plate 220 as the edge of the linear gear position passes through this height difference, thus providing feedback to the user. With the high-heat setting 221 set within the linear gear position, the user can continuously adjust the gas stove's flame when rotating the valve stem 200. For example, when the second end of the positioning element 300 moves from the edge of the linear gear position to the edge of the high-heat setting 221, the gas stove's flame can gradually increase. After the second end of the positioning element 300 moves from the linear gear position to the high-heat setting 221, the gas stove activates the high-heat flame.

[0063] In a specific embodiment, such as Figure 2 , Figure 3 and Figure 8 As shown, the bottom of the arc-shaped groove 223 is provided with two protruding ribs 224. The two protruding ribs 224 are arranged at intervals along the circumference of the rod body 210. The interval between the two protruding ribs 224 defines the stir-fry setting 221. The two protruding ribs 224 are respectively two first guide walls 222 on opposite sides.

[0064] Each rib 224 can be integrally formed on the gear shift plate 220. Each rib 224 can extend radially along the gear shift plate 220. The interval between two ribs 224 is not less than the size of the second end of the positioning member 300, ensuring that the second end of the positioning member 300 can be completely located within the stir-fry gear position 221 between the two ribs 224. It is worth mentioning that when the user rotates the valve stem 200, the second end of the positioning member 300 can pass over the ribs 224 and enter the stir-fry gear position 221. When the second end of the positioning member 300 abuts against the opposite side of the two ribs 224, the first guide wall 222 of the rib 224 can guide the second end of the positioning member 300 into the stir-fry gear position 221.

[0065] This structure, by setting two protruding ribs 224 at intervals in the arc-shaped groove 223 of the linear gear position, defines the high-heat setting 221. When the user adjusts the gas valve 10 from the normal setting to the high-heat setting, the first guide wall 222 on the protruding rib 224 guides the second end of the positioning member 300, allowing it to move quickly into the high-heat setting 221. Furthermore, the first guide wall 222 of the two protruding ribs 224 limits the second end of the positioning member 300, ensuring that when the gas valve 10 is in the high-heat setting 221, the high-heat flame hole 211 and the high-heat flame gas passage 111 are fully connected. By placing the protruding ribs 224 within the arc-shaped groove 223, the side of the protruding ribs 224 facing away from the bottom of the arc-shaped groove 223 will not extend beyond the surface of the gear plate 220, facilitating the second end of the positioning member 300 to pass over the protruding ribs 224 when the user adjusts the gas valve 10 to the high-heat setting. When the second end of the positioning member 300 passes the rib 224, a sound will be emitted between the positioning member 300 and the gear shift plate 220, which can be used to provide feedback to the user.

[0066] In a more specific embodiment, such as Figure 8 As shown, a second guide wall 225 is provided on the opposite side of the two protruding ribs 224, and the second guide wall 225 is inclined in the thickness direction of the gear plate 220. Along the thickness direction of the gear plate 220 away from the bottom of the arc groove 223, the second guide wall 225 gradually approaches the middle of the linear gear in the circumferential direction of the rod body 210.

[0067] The second guide wall 225 can be an inclined surface tilted towards the extending direction of the gear shift disk 220. The angle between the second guide wall 225 and the extending direction of the gear shift disk 220 can be set as needed and is not limited here. Figure 8 As shown, when both the stir-fry setting 221 and the linear setting are located at the top of the setting plate 220, the second guide wall 225 gradually moves away from the stir-fry setting 221 from top to bottom. When the second end of the positioning member 300 abuts against the second guide wall 225, the second guide wall 225 can guide the second end of the positioning member 300 into the linear setting.

[0068] By providing a second guide wall 225 on the rib 224, when the second end of the positioning member 300 moves relative to the gear shift disk 220 from the linear gear position to the stir-fry gear position 221, the second guide wall 225 can guide the second end of the positioning member 300 to pass over the rib 224, making it easier for the user to switch the gear of the gas valve 10. When the second end of the positioning member 300 moves relative to the gear shift disk 220 from the stir-fry gear position 221 to the linear gear position, the second guide wall 225 can guide the second end of the positioning member 300 to move quickly to the linear gear position, making it less likely for backfire to occur when the user switches the gear of the gas valve 10.

[0069] In a specific embodiment, such as Figure 8 and Figure 9 As shown, a third guide wall 226 is provided at the end of the arc-shaped groove 223 along the circumferential direction of the rod 210. The third guide wall 226 is inclined in the thickness direction of the gear shift plate 220. Along the thickness direction of the gear shift plate 220 away from the bottom of the arc-shaped groove 223, the third guide wall 226 gradually moves away from the linear gear position to the middle of the circumferential direction of the rod 210. The third guide wall 226 can be an inclined surface inclined in the extending direction of the gear shift plate 220. When both the stir-fry gear position 221 and the linear gear position are located at the top of the gear shift plate 220, the third guide wall 226 gradually moves away from the linear gear position from bottom to top to the middle of the circumferential direction of the rod 210.

[0070] By setting the third guide wall 226, it can play a certain limiting role on the second end of the positioning member 300. When the user rotates the valve stem 200 with force, the third guide wall 226 can guide the second end of the positioning member 300 to disengage from the linear position, making it convenient for the user to close the gas valve 10.

[0071] In another possible implementation, such as Figure 9 As shown, the stir-fry setting 221 is a groove set at the bottom of the arc-shaped groove 223. The groove is arc-shaped and arranged around the axis of the rod body 210. The two first guide walls 222 are the side walls on opposite sides of the groove rod body 210 in the circumferential direction.

[0072] When the second end of the positioning member 300 is in the high-heat setting 221, it can extend into the groove and align with the bottom of the groove. The first guide wall 222 defined by the side wall of the groove guides and positions the second end of the positioning member 300, allowing the gas valve 10 to quickly switch from the normal setting to the high-heat setting. When the gas valve 10 is in the high-heat setting, the second end of the positioning member 300 extends into the groove, ensuring complete communication between the high-heat flame hole 211 on the valve stem 200 and the high-heat flame gas passage 111 on the valve body 100, preventing backfire in the gas stove's combustion system 30. Furthermore, due to the height difference between the groove and the arc-shaped groove 223, the second end of the positioning member 300 will produce a sound when moving from the linear setting to the high-heat setting 221, providing feedback to the user.

[0073] Indicative, such as Figure 8 and Figure 9 As shown, along the circumference of the rod 210, the stir-fry setting 221 is located in the middle of the linear setting.

[0074] When the second end of the positioning element 300 is in the high-heat setting 221, the user can switch the gas stove from the high-heat setting to the normal setting by rotating the valve stem 200 forward or backward. Optionally, on either side of the high-heat setting 221, rotating the valve stem 200 to move the second end of the positioning element 300 from the edge of the linear setting to the high-heat setting 221 will increase the gas stove's heat output. Users can adjust the gas valve 10's settings more flexibly, improving the user experience.

[0075] In one embodiment, the gas valve 10 further includes an elastic element, one end of which is connected to the valve body 100 and the other end of which is connected to the positioning element 300. The elastic element is configured to cause the positioning element 300 to press against the gear plate 220.

[0076] Understandably, the elastic element can apply a spring force toward the valve body 110 to the positioning element 300. Through the elastic element, the second end of the positioning element 300 can be pressed against the gear plate 220, and thus the first guide surface on the gear plate 220 can reliably guide and limit the second end of the positioning element 300.

[0077] In another embodiment, the elastic element can also be connected between the valve stem 200 and the valve body 100, and the elastic force of the elastic element can drive the gear plate 220 to press against the second end of the positioning element 300.

[0078] In one possible implementation, such as Figure 6 and Figure 7 As shown, the second end of the positioning member 300 is an arc-shaped surface protruding towards the gear shift disk 220. For example, a pin can be used as the positioning member 300. The end of the positioning member 300 facing the gear shift disk 220 forms a protruding arc-shaped surface. This configuration reduces the contact area between the positioning member 300 and the gear shift disk 220, thereby reducing the friction between them. This facilitates the user adjusting the gear of the gas valve 10, and during the adjustment of the gas valve 10 from the normal gear to the stir-fry gear, the first guide wall 222 can more easily guide the positioning member 300.

[0079] In another possible implementation, such as Figure 2 and Figure 3 As shown, a top ball 310 is rotatably mounted on the second end of the positioning member 300, and the top ball 310 abuts against the first side of the gear shift disc 220. The positioning member 300 contacts the gear shift disc 220 through the top ball 310. When the user rotates the valve stem 200, the top ball 310 on the second end of the positioning member 300 rolls on the gear shift disc 220. The friction between the positioning member 300 and the gear shift disc 220 is small, which makes it easier for the user to adjust the gear of the gas valve 10. The first guide wall 222 can more easily guide the positioning member 300.

[0080] like Figure 10 As shown, this utility model also provides a gas stove, including a high-heat flame pipeline 21, a combustion system 30, and the aforementioned gas valve 10. The two ends of the high-heat flame pipeline 21 are respectively connected to the combustion system 30 and the high-heat flame gas passage 111 of the gas valve 10. The additional gas required for high-heat flame can be supplied to the combustion system 30 via the gas valve 10 and the high-heat flame pipeline 21.

[0081] Figure 10 As shown, the gas stove also includes a conventional fire line 22 connected between the combustion system 30 and the gas valve 10. The gas required for the conventional fire can be supplied to the combustion system 30 via the gas valve 10 and the conventional fire line 22.

[0082] The gas stove provided by this utility model, by using the gas valve 10 mentioned above, can ensure an extra gas flow when the high-heat cooking flame is turned on, thus preventing backfire in the combustion system 30 of the gas stove.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 utility model.
