Description

Technical Field

[0001] The utility model relates to the technical field of stage valves, and particularly relates to a stage valve and a gas stove including the same. Background Art

[0002] At present, users' demand for firepower has increased, making stage valves widely used in gas stoves, bringing users a cooking experience with multiple stages of firepower. However, since a stage valve usually includes multiple components, the multiple components need to be assembled on the valve stem and in the valve body in sequence. Among them, the child lock structure is usually arranged in the valve body. For the narrow space in the valve body, the installation of the child lock structure in the valve body makes the assembly of the stopper in the stage valve and the child lock structure have a certain difficulty; at the same time, the relatively large number of components results in a high manufacturing cost of the existing stage valve. Therefore, a stage valve with low assembly difficulty and low cost is needed. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects that the manufacturing cost of the stage valve in the prior art is high and the assembly is difficult, and to provide a stage valve and a gas stove including the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A stage valve, the stage valve includes a valve body and a valve stem, a child lock assembly is arranged on the valve stem, the child lock assembly is arranged at the top of the valve body, the child lock assembly includes a locking part and a lock piece cooperating with the locking part, the lock piece is sleeved on the valve stem, and when the valve stem moves in the downward pressing direction, the lock piece moves along with the valve stem and abuts against the micro switch toggle of the stage valve.

[0006] In this solution, by arranging the child lock assembly outside the valve body, the space in the valve body is saved, so that the stopper in the valve body is easier to assemble, thereby reducing the assembly difficulty of the stage valve and ensuring the child lock function of the stage valve. In addition, the child lock assembly of this stage valve opens the micro switch, so that the child lock assembly not only has the child lock function, but also has the function of opening the micro switch, thereby replacing the traditional stage valve with two separate structures to realize the functions of child lock and opening the micro switch. The integrated setting method omits the structure originally used for opening the micro switch function, mainly the push plate and the valve body valve cover and other components used for separately pressing the micro switch in the downward pressing direction. This not only further reduces the manufacturing cost of the stage valve, but also simplifies the structure of the stage valve. Moreover, the space utilization rate inside and outside the valve body of the simplified stage valve is more reasonable during assembly, reducing the setting of additional components in the valve body to reduce the risk of valve body leakage and ensure the use safety of the stage valve.

[0007] Preferably, the locking part includes a bottom plate and a locking rod located on the bottom plate. The bottom plate is arranged on the top of the valve body, and the bottom plate is sealingly connected to the valve body. The locking piece has a notch, and one end of the locking rod extends into the notch and cooperates with the notch.

[0008] In this solution, the child lock function of the stage valve is realized by arranging the locking rod to cooperate with the notch of the locking piece. In addition, the sealing performance of the valve body is ensured by the sealing connection between the bottom plate and the valve body.

[0009] Preferably, the locking rod is arranged along the downward pressing direction of the valve rod, and the end of the locking rod extending into the notch is arranged along a direction perpendicular to the downward pressing direction.

[0010] In this solution, through the above arrangement, after the locking piece moves and disengages from the locking of the end of the locking rod, it can rotate smoothly and abut against the microswitch toggle piece, preventing the situation of structural interference between the locking rod and the moved locking piece.

[0011] Preferably, a through hole corresponding to the valve rod is arranged on the bottom plate, and a guiding part is arranged in the through hole, and the guiding part extends towards the inside of the valve body.

[0012] In this solution, by arranging the guiding part, while omitting the valve cover of the valve body, the valve rod is limited and guided by the guiding part, avoiding the situation that the valve rod deviates from the axial direction when pressed down and cannot be reset or the ignition fails.

[0013] Preferably, a protruding part is arranged on the bottom plate, and the protruding part is arranged on the outer peripheral side of the guiding part. The protruding part is used to cooperate with the limiting rod on the valve rod, and the end of the guiding part away from the bottom plate is flush with the end of the protruding part away from the bottom plate.

[0014] In this solution, by arranging the protruding part, when the valve rod of the stage valve rotates, the limiting rod on the valve rod cooperates with the protruding part to feedback the gear feel to the user's hand. The flush setting of the end of the guiding part and the protruding part can avoid interference with the limiting rod and ensure the guiding effect on the valve rod at the same time.

[0015] Preferably, the guiding part is a sleeve, and the guiding part is integrally formed with the bottom plate.

[0016] In this solution, through the above arrangement, the assembly difficulty of the stage valve is reduced.

[0017] Preferably, an installation part is arranged on the bottom plate, and the installation part is arranged horizontally on the side of the valve rod. The microswitch of the stage valve is arranged on the installation part.

[0018] In this solution, through the above arrangement, the microswitch toggle piece is arranged along the downward pressing direction of the valve rod and abuts against the locking piece smoothly.

[0019] Preferably, the height of the installation part is higher than that of the bottom plate, and the top height of the microswitch paddle is the same as the initial height of the locking piece.

[0020] In this solution, through the above settings, the stage valve can respond quickly during ignition. When the locking piece disengages from the locking rod, it abuts against the microswitch paddle at the same time, reducing the ignition time required.

[0021] Preferably, the stage valve further includes a return spring, the return spring is sleeved on the valve rod, and the return spring is located between the bottom plate and the locking piece.

[0022] In this solution, through the above settings, the reset of the valve rod after use is realized. By setting the return spring outside the valve body, compared with the situation where part of the return spring is set inside the valve body, on the one hand, it can reduce the possible gas leakage caused by the part of the return spring being set inside the valve body, and on the other hand, it can reduce the assembly difficulty of the stage valve, and one end of the return spring is directly abutted against the bottom plate for assembly.

[0023] A gas stove, the gas stove includes the stage valve as described above.

[0024] In this solution, the gas stove includes the above stage valve, so that the manufacturing cost of the gas stove is correspondingly reduced, the structure is simpler, and the assembly difficulty is correspondingly reduced.

[0025] The positive and progressive effects of the present utility model are as follows: By arranging the child lock component outside the valve body, the present utility model saves the space inside the valve body, making it easier to assemble the stopper inside the valve body, reducing the assembly difficulty of the stage valve, and at the same time ensuring the child lock function of the stage valve. In addition, the stage valve of the present utility model opens the microswitch through the child lock component, so that the child lock component not only has the child lock function but also has the function of opening the microswitch, thus replacing the traditional stage valve that separately sets two structures to realize the child lock and the function of opening the microswitch. The integrated setting method omits the structure originally used for opening the microswitch function alone, mainly omitting components such as the push plate and the valve body cover that are used to separately squeeze the microswitch along the pressing direction. This not only further reduces the manufacturing cost of the stage valve, simplifies the structure of the stage valve accordingly, but also makes the space utilization rate inside and outside the valve body more reasonable during the assembly of the simplified stage valve, reduces the setting of extra components inside the valve body, reduces the risk of valve body leakage, and ensures the use safety of the stage valve.

[0046] The following is a preferred embodiment and will be combined with the accompanying drawings to more clearly and completely illustrate the present utility model.

[0047] This embodiment provides a stage valve, and the specific structure is as Figure 1 , Figure 2 and Figure 3 shown. The stage valve includes a valve body 1 and a valve rod 2. A child lock assembly 3 is provided on the valve rod 2. The child lock assembly 3 is disposed at the top of the valve body 1. The child lock assembly 3 includes a locking portion 31 and a locking piece 32 that cooperates with the locking portion 31. The locking piece 32 is sleeved on the valve rod 2. When the valve rod 2 moves in the downward pressing direction, the locking piece 32 moves with the valve rod 2 and abuts against the microswitch paddle 4 of the stage valve.

[0048] Specifically, the valve body 1 is provided with a valve cavity for accommodating the shutter. The valve stem 2 is coaxially connected to the shutter so as to drive the shutter to rotate through the valve stem 2 to achieve the firepower configuration of the stage valve. This is the prior art and will not be elaborated here. A child lock assembly 3 is sleeved on the part of the valve stem 2 outside the valve body 1. The child lock assembly 3 locks the valve stem 2 in a direction perpendicular to the pressing-down direction to prevent children from accidentally touching and opening the stage valve. By arranging the child lock assembly outside the valve body, the space inside the valve body is saved, so that the shutter inside the valve body is easier to assemble, thereby reducing the assembly difficulty of the stage valve and ensuring the child lock function of the stage valve at the same time.

[0049] The child lock assembly 3 includes a locking part 31 and a lock piece 32. Among them, the lock piece 32 is of a disc-shaped structure and the lock piece 32 is coaxially arranged with the valve stem 2 through a circlip or a retaining ring, so that when the valve stem 2 moves along the pressing-down direction, the lock piece 32 moves along with the valve stem 2. During the movement of the disc-shaped lock piece 32, the edge of the lock piece 32 can abut against the microswitch toggle piece 4, so as to integrate the child lock function and the function of triggering the microswitch on the child lock assembly 3, thereby replacing the traditional stage valve with two separate structures to realize the functions of child lock and opening the microswitch. The integrated setting method omits the structure originally used for opening the microswitch function alone. The main structures omitted are the push plate for separately pressing the microswitch along the pressing-down direction and the valve body valve cover covering the valve body 1 and other components. This not only further reduces the manufacturing cost of the stage valve and simplifies the structure of the stage valve accordingly, but also when the simplified stage valve is assembled, since the child lock assembly 3 is arranged outside the valve body 1, only the shutter needs to be accommodated in the valve cavity of the valve body 1, so that the space utilization rate inside and outside the valve body 1 is more reasonable, reducing the setting of additional components inside the valve body 1 to reduce the leakage risk of the valve body 1 and ensuring the use safety of the stage valve.

[0050] It can be understood that in this embodiment, the microswitch on the stage valve is arranged in a direction perpendicular to the pressing-down direction of the valve stem 2. For example, the valve stem 2 presses down in the vertical direction and the microswitch is arranged in the horizontal direction, so that the microswitch toggle piece 4 can correspond to the pressing-down direction of the valve stem 2 and the microswitch is opened by the abutment of the lock piece 32.

[0051] Of course, in other embodiments, the lock piece 32 can also be of a fan-shaped structure or other structures, and the purpose is to be able to abut against the microswitch when the lock piece 32 moves, and its shape is not limited.

[0052] As Figure 4 shown, in this embodiment, the locking part 31 includes a bottom plate 311 and a lock rod 312 located on the bottom plate 311. The bottom plate 311 is arranged on the top of the valve body 1, and the bottom plate 311 is hermetically connected to the valve body 1. The lock piece 32 has a notch 321, and one end of the lock rod 312 extends into the notch 321 and cooperates with the notch 321.

[0053] Specifically, the closing element is limited within the valve body 1 by the bottom plate 311. The locking rod 312 is vertically arranged on the bottom plate 311. The end of the locking rod 312 away from the bottom plate 311 is used to cooperate with the notch 321 of the locking piece 32. The end of the locking rod 312 close to the bottom plate 311 is integrally formed with the bottom plate 311. The shape of the notch 321 of the locking piece 32 can be consistent with the end of the locking rod 312. For example, the rectangular notch 321. The position where the notch 321 of the locking piece 32 is located is deflected by 35° from the position where the positioning surface of the valve rod 2 is located. From the appearance, the part of the end of the locking rod 312 extending into the notch 321 is a triangular structure, thereby realizing the child lock function.

[0054] In this embodiment, a sealing ring made of rubber can also be provided between the bottom plate 311 and the valve body 1 to ensure the sealing performance after assembly. This is prior art and will not be elaborated here.

[0055] In this embodiment, the locking rod 312 is arranged along the downward pressing direction of the valve rod 2, and the end of the locking rod 312 extending into the notch 321 is arranged in a direction perpendicular to the downward pressing direction.

[0056] Specifically, the locking rod 312 has an "L" - shaped structure and is located at the edge of the locking piece 32. When the locking piece 32 moves with the valve rod 2, the notch 321 disengages from the end of the locking rod 312, and the locking piece 32 can rotate with the valve rod 2 while following the downward pressing of the valve rod 2, avoiding the edge of the locking piece 32 contacting the end of the locking rod 312 close to the bottom plate 311 and causing structural interference.

[0057] As Figure 5 shown, in this embodiment, a through - hole 5 corresponding to the valve rod 2 is provided on the bottom plate 311, and a guiding portion 6 is arranged in the through - hole 5, and the guiding portion 6 extends towards the inside of the valve body 1.

[0058] Specifically, the through - hole 5 penetrates the bottom plate 311, and the valve rod 2 passes through the through - hole 5 to be connected to the closing element. The guiding portion 6 is arranged at the bottom of the bottom plate 311 and extends towards the inside of the valve body 1. When the valve rod 2 passes through the through - hole 5, the movement of the valve rod 2 is guided by the guiding portion 6, and the valve rod 2 is limited in the initial state, that is, when the valve rod 2 does not move. By omitting the valve cover of the valve body, the valve rod 2 is limited and guided by the guiding portion 6, ensuring that the valve rod 2 is always in the axial direction, avoiding the situation that the valve rod 2 cannot be reset or the ignition fails due to the lack of components such as the valve body valve cover and deviating from the axial direction. The repeated utilization rate and reliability of the stage - lifting valve are improved.

[0059] Furthermore, a protruding portion 7 is provided on the bottom plate 311. The protruding portion 7 is arranged on the outer peripheral side of the guiding portion 6. The protruding portion 7 is used to cooperate with a limiting rod (not shown in the figure) on the valve rod 2. The end of the guiding portion 6 away from the bottom plate 311 is flush with the end of the protruding portion 7 away from the bottom plate 311.

[0060] Specifically, a limiting rod is provided on the valve stem 2. The limiting rod is perpendicular to the extending direction of the valve stem 2 and is used to cooperate with the limiting groove on the shutter. The limiting rod is clamped in the limiting groove to enable the valve stem 2 to rotate and drive the shutter to rotate, so as to realize the firepower configuration of the stage valve. This is the prior art and will not be elaborated here. The protruding part 7 is annularly arranged on the outer peripheral side of the guiding part 6 in a fan-shaped structure. The extending direction of the protruding part 7 is the same as that of the guiding part 6. A plurality of grooves are arranged at intervals on the protruding part 7. The grooves are used to cooperate with the limiting rod to feedback the gear feel to the valve stem 2 and the user's hand when the shutter outputs different gas volumes by engaging the limiting rod with the grooves when the valve stem 2 rotates.

[0061] It can be understood that the end parts of the guiding part 6 and the protruding part 7 are arranged flush, which can avoid interference between the end part of the guiding part 6 and the limiting rod when the limiting rod engages with the protruding part 7, and at the same time ensure the guiding effect on the valve stem 2.

[0062] In this embodiment, the guiding part 6 is a sleeve, and the guiding part 6 is integrally formed with the bottom plate 311. By integrally forming the guiding part 6 and the bottom plate 311, compared with the detachable connection method of the guiding part 6 and the bottom plate 311, the assembly steps can be reduced, and thus the assembly difficulty of the stage valve can be reduced.

[0063] In another implementation manner, the guiding part 6 can also be at least two arc-shaped plates arranged oppositely to limit and guide the valve stem 2 in a way of clamping the valve stem 2. The purpose is also to ensure that the valve stem 2 is always in the axial direction and will not be elaborated here.

[0064] In this embodiment, an installation part 8 is provided on the bottom plate 311. The installation part 8 is arranged horizontally on the side of the valve stem 2, and the microswitch of the stage valve is arranged on the installation part 8.

[0065] Specifically, the installation part 8 is a plane for carrying the microswitch. Threaded holes are provided on the installation part 8 to screw the microswitch onto the installation part 8 through bolt assemblies. The installation part 8 is integrally formed with the bottom plate 311 to reduce the assembly difficulty. By providing the installation part 8, the microswitch dial 4 can be set along the pressing direction of the valve stem 2 and can be smoothly abutted against the lock piece 32.

[0066] In this embodiment, the height of the installation part 8 is higher than the height of the bottom plate 311, and the top height of the microswitch dial 4 is the same as the initial height of the lock piece 32.

[0067] Specifically, the installation part 8 is a bearing plane formed by bending the edge of the lock piece 32 corresponding to the bottom plate 311. Since the thickness of the microswitch is less than the distance between the bottom plate 311 and the lock piece 32, the height of the installation part 8 is set to be higher than the height of the bottom plate 311. When the microswitch is horizontally installed on the installation part 8, the microswitch paddle 4 is kept corresponding to the moving direction of the lock piece 32 following the downward pressure of the valve stem 2, so as to ensure that the microswitch paddle 4 can be smoothly opened and prevent the situation that the moving distance of the lock piece 32 is small and the microswitch cannot be opened.

[0068] Moreover, the top height of the microswitch paddle 4 is the same as the initial height of the lock piece 32, which enables the stage valve to respond quickly and ignite smoothly during ignition, that is, when the lock piece 32 disengages from the lock rod 312, it abuts against the microswitch paddle 4 at the same time, reducing the ignition time required.

[0069] In this embodiment, the stage valve further includes a return spring 9. The return spring 9 is sleeved on the valve stem 2, and the return spring 9 is located between the bottom plate 311 and the lock piece 32.

[0070] Specifically, the return spring 9 is a spring used to reset the valve stem 2 in the prior art. In this embodiment, the return spring 9 is arranged outside the valve body 1. Compared with the traditional way of arranging the spring part inside the valve body 1, on the one hand, it can save the internal space of the valve body 1, improve the space utilization rate, and arranging the return spring 9 outside the valve body 1 can reduce the assembly difficulty of inserting part of the spring into the valve body 1 for assembly, and prevent possible gas leakage caused by arranging part of the spring inside the valve body 1.

[0071] On the other hand, while simplifying the parts of the stage valve, the set size of the return spring 9 can be made smaller, that is, the length of the return spring 9 is reduced. For example, the length of the return spring 9 is reduced by one half, and the elastic force is also correspondingly reduced, thereby reducing the downward pressure of the stage valve and making it more labor-saving for users to use this stage valve and improving the user experience.

[0072] This embodiment also provides a gas stove, and the gas stove includes the above-mentioned stage valve.

[0073] Specifically, the gas stove includes a stove bottom box, a stove panel, a burner and the above-mentioned stage valve. Among them, the stage valve is arranged in the stove bottom box, the stove panel covers the stove bottom box, part of the burner extends out of the stove panel and the burner is communicated with the stage valve, and gas is supplied to the burner through the stage valve to meet the cooking needs of users. And the stage valve with a more simplified structure reduces the manufacturing cost of the gas stove accordingly, and the structure is simpler and the assembly difficulty is correspondingly reduced.

[0074] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present utility model.
