Description

Technical Field

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

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas, coal gas, natural gas, or other gaseous fuels for open-flame heating. A valve is installed in the gas line of a gas stove to control the flow of gas and regulate its volume. Currently, there are two main types of burners in gas stoves: top-intake burners and bottom-intake burners. Both types are connected to the gas source via valves. However, due to the structural differences between top-intake and bottom-intake burners, separate valves are required for each type. This separate valve design necessitates separate molds, increasing production costs. Utility Model Content

[0033] like Figures 1 to 7 As shown, this embodiment provides a valve body structure for a gas stove, which is installed on the burner of the gas stove to control the on / off state of the gas circuit and regulate the gas flow. The burner includes an upper air intake burner and a lower air intake burner. The upper air intake burner is connected to the valve body structure of the gas stove via an air intake pipe 100, and the lower air intake burner is connected to the valve body structure of the gas stove via a nozzle 200. This valve body structure of the gas stove improves the versatility of the valve body structure by providing an air outlet pipe 2 on the valve body 1. The end of the air outlet pipe 2 facing the burner is provided with a first connection structure and a second connection structure. The first connection structure is detachably connected to the air intake pipe 100, and the second connection structure is detachably connected to the nozzle 200. This solves the problem of increased opening costs caused by designing different valve body structures for different burners.

[0034] Specifically, the gas stove valve body structure provided in this embodiment includes a valve body 1 and a gas outlet pipe 2. The valve body 1 is used to connect to an external gas source and to communicate with the external gas source. The gas outlet pipe 2 is disposed on the valve body 1, with one end connected to the valve body 1 and the other end connected to the burner, so that the gas from the external gas source can be sequentially delivered to the burner through the valve body 1 and the gas outlet pipe 2. A first connecting structure and a second connecting structure are respectively provided on the outer wall and inner wall of the end of the gas outlet pipe 2 opposite to the valve body 1. A gas passage 24 for gas flow is formed inside the gas outlet pipe 2, with the first connecting structure located on the outer wall of the gas outlet pipe 2 and the second connecting structure located on the side wall of the gas passage 24. When the gas stove valve body structure is installed on an upper air intake burner, the air intake pipe 100 in the upper air intake burner is detachably connected to the first connecting structure; when the gas stove valve body structure is installed on a lower air intake burner, the nozzle 200 in the lower air intake burner is detachably connected to the second connecting structure.

[0035] Specifically, the first connection structure is an external thread 25, and the second connection structure is an internal thread 26.

[0036] Specifically, the outer wall of the gas outlet pipe 2 is provided with at least two symmetrically arranged clamping surfaces 23. When installing the gas stove valve body structure and burner, a wrench is used to clamp the gas outlet pipe 2 onto the two symmetrically arranged clamping surfaces 23 to fix the gas stove valve body structure and complete the threaded connection between the gas outlet pipe 2 and the burner. To facilitate clamping operations, the gas outlet pipe 2 is provided with multiple clamping surfaces 23. These multiple clamping surfaces 23 are arranged in pairs, with two clamping surfaces 23 in the same pair being symmetrically arranged. Two clamping surfaces 23 in the same pair correspond to one wrench clamping direction. Providing multiple sets of clamping surfaces 23 allows the gas outlet pipe 2 to have multiple wrench clamping directions, facilitating the selection of a suitable clamping direction during installation and further improving installation convenience. The multiple clamping surfaces 23 are arranged in a ring along the circumference of the gas outlet pipe 2, that is, the multiple clamping surfaces 23 are connected end-to-end in sequence. The overall structure of the clamping surfaces 23 is similar to that of a nut. In some embodiments, the overall structure of the clamping surface 23 can be configured as a regular square, a regular hexagon, or a regular octagon, etc.

[0037] Specifically, the vent pipe 2 includes a first pipe section 21 and a second pipe section 22. One end of the first pipe section 21 is connected to the valve body 1, and the other end is connected to the second pipe section 22. The first pipe section 21 and the second pipe section 22 are integrally formed. An external thread 25 is provided on the outer wall of the second pipe section 22, and an internal thread 26 is provided on the inner wall of the second pipe section 22. A clamping surface 23 is provided on the outer wall of the second pipe section 22, and the clamping surface 23 is located on the side of the external thread 25 closer to the valve body 1. The outer diameter of the second pipe section 22 is larger than the outer diameter of the first pipe section 21. On the one hand, since the outer diameter of the second pipe section 22 is larger than that of the first pipe section 21, it is beneficial to increase the wall thickness of the second pipe section 22, thereby providing sufficient space for machining the external thread 25 and the internal thread 26. On the other hand, the relatively large outer diameter of the second pipe section 22 makes the distance between the two clamping surfaces 23 larger, which is more conducive to clamping the vent pipe 2 with a wrench.

[0038] Specifically, the air passage 24 is formed within the first pipe section 21 and the second pipe section 22. The air passage 24 includes a first air passage 241 and a second air passage 242. One end of the first air passage 241 communicates with the valve body 1, and the other end communicates with the second air passage 242. In this embodiment, the first air passage 241 is formed within the first pipe section 21, and the end of the first air passage 241 facing away from the valve body 1 extends into the second pipe section 22. The second air passage 242 is located at the end of the second pipe section 22 facing away from the first pipe section 21. The diameter of the second air passage 242 is larger than the diameter of the first air passage 241, and the internal thread 26 is provided on the side wall of the first air passage 241. This structure allows the second air passage 242 to be used as clearance space during installation, and a portion of the structure of the connector end in the air inlet pipe 100 or nozzle 200 can be accommodated within the second air passage 242. Of course, in some embodiments, if clearance from the connector end structure is not required, the internal thread 26 can also be provided on the side wall of the second air passage 242.

[0039] Specifically, the valve body 1 is provided with two gas outlet pipes 2, which are parallel and flush with the ends of the two gas outlet pipes 2 that are away from the valve body 1, to accommodate the connection position distribution in the burner. The valve body structure for the gas stove also includes a connecting pipe 3 and a reinforcing rib 4. One of the gas outlet pipes 2 is connected to the valve body 1 through the connecting pipe 3 to accommodate the spatial layout of the two parallel gas outlet pipes 2. The two gas outlet pipes 2 are connected by the reinforcing rib 4 to raise the mechanical cavity bottom of the gas outlet pipes 2, prevent positional misalignment between the two gas outlet pipes 2, and ensure that the gas outlet ends of the two gas outlet pipes 2 can match the installation position of the burner. Both gas outlet pipes 2 are straight pipes. One gas outlet pipe 2 is directly connected to the valve body 1, and the other gas outlet pipe 2 is connected to the valve body 1 through the connecting pipe 3. In one optional embodiment, the angle between the connecting pipe 3 and the corresponding gas outlet pipe 2 is α, where α is an obtuse angle. In another optional embodiment, the angle between the connecting pipe 3 and the corresponding gas outlet pipe 2 is α, where α is a right angle. In practical applications, the angle of α can be reasonably selected according to the specific installation space of the valve body structure of the gas stove to adapt to the overall space design of the gas stove so that the gas outlet pipe 2 can avoid other components.

[0040] Specifically, the valve body 1 includes a fixed seat 12 and a valve shaft 11. The fixed seat 12 is used to connect to an external gas source. The fixed seat 12 is located on the side of the valve body 1 opposite to the gas outlet pipe 2. A mounting surface 121 for connecting to the external gas source is formed on the fixed seat 12, that is, the mounting surface 121 is located on the side of the valve body 1 opposite to the gas outlet pipe 2. The mounting surface 121 is parallel to the end face of the gas outlet pipe 2 opposite to the valve body 1. This structure makes the connection position of the gas outlet pipe 2 to the burner and the connection position of the valve body 1 to the external gas source located on opposite sides of the valve body structure of the gas stove, which is beneficial to the spatial layout of the entire gas stove and makes the arrangement of the burner and the external gas source more adaptable to the usage scenario. A gas passage for gas flow is formed inside the valve body 1. The gas inlet of the gas passage is set on the mounting surface 121 of the fixed seat 12 so that the gas from the external gas source enters the gas passage of the valve body 1 through the gas inlet. Both gas outlet pipes 2 are connected to the gas passage inside the valve body 1. A valve core is also installed inside the gas passage. A valve shaft 11 is connected to the valve core. Rotating the valve shaft 11 controls the movement of the valve core, thereby opening, closing, or adjusting the degree of gas passage flow. A knob 13 is also provided on the valve shaft 11 for convenient adjustment by the user. In this embodiment, one gas outlet pipe 2 is directly connected to the valve body 1. The axis of this gas outlet pipe 2 is on the same plane as the axis of the valve shaft 11; this gas outlet pipe 2 is called the inner gas outlet pipe. The other gas outlet pipe 2 is connected to the valve body 1 via a connecting pipe 3; this gas outlet pipe 2 is called the outer gas outlet pipe. The axis of the connecting pipe 3 is on the same plane as the axis of the valve shaft 11, and there is an angle between the axis of the connecting pipe 3 and the axis of the inner gas outlet pipe. When the valve shaft 11 is opened, the gas inside the valve body 1 enters the two gas outlet pipes 2.

[0041] like Figure 3 and Figure 4 As shown, this embodiment also provides a gas stove, including an upper-intake burner and a valve body structure for the gas stove. The upper-intake burner includes an intake pipe 100, which is threadedly connected to the external thread 25 in the valve body structure for the gas stove. Specifically, the upper-intake burner is prior art, and its specific structure and working principle will not be described in detail here. The intake pipe 100 includes a pipe body and a connecting nut 110 sleeved on the pipe body. A limiting part 120 is provided at the end of the pipe body, which protrudes from the outer wall of the pipe body to prevent the connecting nut 110 from falling off the pipe body. The upper-intake burner also includes a burner head for placing cooking utensils, and the other end of the pipe body is connected to the burner head. There are two intake pipes 100, and the two intake pipes 100 correspond one-to-one with the two outlet pipes 2. During installation, insert one end of the air tube body into the air outlet tube 2, with the limiting part 120 accommodated in the second air passage 242, and then screw the connecting nut 110 onto the external thread 25 of the air outlet tube 2.

[0042] like Figures 5 to 7 As shown, this embodiment also provides a gas stove, including a bottom-intake burner and a valve body structure for the gas stove. The bottom-intake burner includes a nozzle 200, an air damper 300, and a spring 400. One end of the nozzle 200 is provided with a threaded connector 210, and the nozzle 200 is threadedly connected to the internal thread 26 in the valve body structure for the gas stove through the threaded connector 210. Specifically, the bottom-intake burner is prior art, and its specific structure and working principle will not be described in detail here. The bottom-intake burner also includes a burner head for placing cooking utensils. One end of the nozzle 200 is connected to the burner head, and the other end is provided with a threaded connector 210 that mates with the internal thread 26, so that the threaded connector 210 is inserted into the gas outlet pipe 2 and threadedly connected to the internal thread 26. The air damper 300 is installed on the nozzle 200 and is used to control the air intake. The spring 400 is sleeved on the periphery of the nozzle 200, and the spring 400 is used to press the air damper 300 against the nozzle.

[0043] In this embodiment, by providing a gas outlet pipe 2 on the valve body structure of the gas stove, and connecting it to the lower air inlet burner via the internal thread 26 on the gas outlet pipe 2, and to the upper air inlet burner via the external thread 25 on the gas outlet pipe 2, the versatility of the gas stove valve body structure is improved. The gas stove valve body structure only requires one mold opening, which helps reduce design and manufacturing costs.

[0044] In another alternative embodiment, the first and second connecting structures can also be existing snap-fit ​​and plug-in structures. Correspondingly, the connecting end of the intake pipe 100 is configured to cooperate with the first connecting structure so that the intake pipe 100 is snap-fitted or plugged into the first connecting structure for fixation. The connecting end of the nozzle 200 is configured to cooperate with the second connecting structure so that the nozzle 200 is snap-fitted or plugged into the second connecting structure for fixation.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
