Description

Technical Field

[0001] This invention relates to the field of gas stoves, and particularly to a stopcock valve and a stove. Background Technology

[0002] In conventional stopcock valve structures, the valve body only contains a child lock, which can be released by pressing down. After that, any heat adjustment can be made. This heat adjustment is stepless, and the user cannot precisely adjust to a specific heat level. For example, when the user wants to keep the heat high for stir-frying, they cannot accurately know when the knob has been adjusted to high heat. They need to look at the flame to adjust it. Moreover, the intensity of the flame seen with the naked eye is not accurate, and it is easy to adjust the high heat to medium heat. Therefore, it is desirable to have an accurate adjustment prompt during operation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect in the prior art that users cannot accurately adjust to a specific fire level using a stopcock valve, and to provide a stopcock valve and a stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A plug valve includes: a pressure rod, an adjusting ring, a pressure plate, a child lock plate, and a first elastic element.

[0006] The pressure bar passes through the adjusting ring, pressure plate and child lock piece from top to bottom;

[0007] The pressure plate includes a first limiting block protruding downwards;

[0008] The adjusting ring is configured to be movable in the vertical direction, and the adjusting ring includes a second limiting block that protrudes downward and passes through the pressure plate;

[0009] The child lock plate is fixedly connected to the pressure rod and has an opening;

[0010] The first elastic element is used to apply force to the child lock piece in the direction that causes the child lock piece to move upward;

[0011] The lever can rotate from the first state to the second state;

[0012] In the first state, the opening is fitted onto the first limiting block; in the second state, the opening is fitted onto the second limiting block.

[0013] In this design, the plug valve has two states. In the first state, the opening of the child lock plate is fitted onto the first limiting block of the pressure plate, achieving a limiting position. When the pressure rod is pressed, the first elastic element is compressed, and the child lock plate moves down with the pressure rod, disengaging from the first limiting block. At this time, the pressure rod is rotated, and when the child lock plate rotates with the pressure rod until the opening reaches the second limiting block, the first elastic element rebounds upward, moving the child lock plate upward, and the opening of the child lock plate will fit onto the second limiting block, achieving a limiting position. The two states can be freely switched by pressing and rotating the pressure rod, and both can be locked. When rotated to the second state, because the second limiting block is inserted into the opening of the child lock, the pressure rod can no longer be rotated, thus giving the user a prompt that the plug valve has been rotated into the second state, thereby facilitating the user to accurately control the adjustment of specific firepower.

[0014] Preferably, the plug valve further includes a second elastic element for applying force to the adjusting ring in a direction that causes the adjusting ring to move downward.

[0015] In this design, the second elastic element is used to press the adjusting ring to prevent the adjusting ring from moving upward due to the child lock plate rebounding when the plug valve enters the second state, which would prevent the opening of the child lock plate from being fitted onto the second limit block, thus preventing the second state from being locked.

[0016] Preferably, the plug valve further includes a knob, which is sleeved on the top of the pressure rod.

[0017] In this design, the knob is mounted on the top of the pressure bar, increasing the volume of the upper part of the pressure bar and making it easier for users to press and rotate the pressure bar, thus making operation more convenient.

[0018] Preferably, the adjusting ring is provided with an operating wall in the circumferential direction, and the operating wall is located on the outer periphery of the knob.

[0019] In this design, the operating wall is located on the outer periphery of the knob, allowing the user to lift the adjusting ring when switching to the second state, causing the second limit block to disengage from the opening of the child lock piece, thus unlocking the second state.

[0020] Preferably, the pressure plate has a through hole, and the second limiting block is inserted into the through hole.

[0021] In this design, the adjusting ring is located on the upper side of the pressure plate, and the child lock plate is located on the lower side of the pressure plate. A through hole is provided on the pressure plate so that the limiting block protruding downward on the adjusting ring can contact the child lock plate, facilitating state switching.

[0022] Preferably, in the first state, the second limiting block abuts against the upper surface of the child lock plate.

[0023] In this solution, in the first state, the opening of the child lock piece is fitted onto the first limiting block. Since the second limiting block abuts against the upper surface of the child lock piece, the child lock piece cannot move upward, thus achieving locking in the first state.

[0024] Preferably, in the second state, the first limiting block abuts against the upper surface of the child lock piece.

[0025] In this solution, in the second state, the opening of the child lock piece is fitted onto the second limiting block. Since the first limiting block abuts against the upper surface of the child lock piece, the child lock piece cannot move upward, thus achieving locking in the second state.

[0026] Preferably, the first limiting block and the second limiting block are 90°-180° apart in the circumferential direction.

[0027] In this scheme, the first limiting block and the second limiting block are separated by a certain angle, providing a large range of firepower adjustment sections so that the firepower status can be clearly distinguished.

[0028] Preferably, the pressure bar includes a pressure plate, the lower surface of which abuts against the upper surface of the child lock plate.

[0029] In this solution, the pressure bar needs to be able to move the child lock piece downwards when pressed to unlock the device. Adding a pressure plate to the side wall of the pressure bar can form a horizontal contact surface with the child lock piece, thereby enabling the child lock piece to move downwards when the pressure bar is pressed.

[0030] Preferably, the child lock plate has a sleeve hole, the pressure rod passes through the sleeve hole, and the side wall of the sleeve hole is a limiting surface, which is used to prevent the pressure rod from rotating freely in the sleeve hole.

[0031] In this solution, the pressure rod needs to be able to rotate to drive the child lock plate to switch between the first and second states. A sleeve hole is provided on the child lock plate, and the side wall of the sleeve hole is a limiting surface. The limiting surface is used to prevent the pressure rod from rotating freely in the sleeve hole, so that the child lock plate can be driven to rotate when the pressure rod rotates.

[0032] A stove, including the above-mentioned stopcock valve.

[0033] The positive and progressive effects of this invention are as follows: the plug valve has two states. In the first state, the opening of the child lock plate is fitted onto the first limiting block of the pressure plate to achieve limiting. When the pressure rod is pressed, the first elastic element is compressed, and the child lock plate moves down with the pressure rod and disengages from the first limiting block. At this time, the pressure rod is rotated. When the child lock plate rotates with the pressure rod until the opening reaches the second limiting block, the first elastic element rebounds upward and moves the child lock plate upward. The opening of the child lock plate will then fit onto the second limiting block to achieve limiting. The two states can be freely switched by pressing and rotating the pressure rod, and can be stably limited, solving the defect of the plug valve that cannot stably switch between multiple states.

[0056] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0057] like Figure 1-4 As shown, this embodiment provides a plug valve 100, which includes: a pressure rod 110, an adjusting ring 130, a pressure plate 120, a child lock plate 140, and a first elastic element 150.

[0058] The first elastic element 150 is a spring.

[0059] The pressure rod 110 is sequentially inserted from top to bottom through the adjusting ring 130, the pressure plate 120, the child lock piece 140, and the first elastic element 150.

[0060] The pressure plate 120 includes a first limiting block 121 that protrudes downward.

[0061] The adjusting ring 130 is configured to be movable in the vertical direction. The adjusting ring 130 includes a second limiting block 131 protruding downward, which passes through the pressure plate 120.

[0062] The child lock plate 140 is fixedly connected to the pressure rod 110 and has an opening 141 at its edge.

[0063] In other embodiments, the opening 141 on the child lock plate 140 may also be opened in the middle part of the child lock plate 140, but the opening 141 should be able to change position along the circumference of the child lock plate 140 when the child lock plate 140 is rotated, so as to ensure that it can achieve state switching.

[0064] The first elastic element 150 is used to apply force to the child lock piece 140 in the direction that causes the child lock piece 140 to move upward.

[0065] The pressure rod 110 can rotate from the first state to the second state, and the rotation angle is 170°, that is, the circumferential angle between the first limiting block 121 and the second limiting block 131 along the pressure rod 110 is 170°.

[0066] The first state is the initial state. Figure 1 As shown), the second state can be a stir-fry state or a synchronized fire state, etc. In other embodiments, those skilled in the art can make other changes to the mode of the second state according to the needs of use, and the circumferential angle between the first limiting block 121 and the second limiting block 131 along the pressure rod 110 can be other values ​​greater than 0, which can be changed according to the changes in operational requirements. Optionally, the circumferential interval angle between the first limiting block 121 and the second limiting block 131 is 90°-180°. This angle can be selected according to the rotation angle corresponding to the actual firepower to be indicated. Since the firepower to be indicated is usually high firepower, the preferred interval angle is 90°-180°.

[0067] In the first state, the opening 141 is fitted onto the first limiting block 121, and in the second state, the opening 141 is fitted onto the second limiting block 131.

[0068] The plug valve 100 has two states. In the first state, the opening 141 of the child lock plate 140 is fitted onto the first limiting block 121 of the pressure plate 120, achieving a limiting position. When the pressure rod 110 is pressed, the first elastic element 150 is compressed, and the child lock plate 140 moves down with the pressure rod 110, disengaging from the first limiting block 121. At this time, the pressure rod 110 is rotated. After rotating 170°, the opening 141 of the child lock plate 140 reaches the second limiting block 131, and the first elastic element 150 springs back upward, locking the child lock plate. 140 moves upward, and the opening 141 of the child lock plate 140 is fitted onto the second limit block 131 to achieve a limit; the two states can be freely switched by pressing and rotating the lever 110, and both can be locked. When rotated to the second state, since the second limit block 131 is inserted into the opening of the child lock plate 140, the lever 110 can no longer be rotated, thus giving the user a prompt that the stop valve 100 has been rotated into the second state, so that the user can accurately control the adjustment of specific firepower.

[0069] In this embodiment, the plug valve 100 further includes a second elastic element 160, which is used to apply force to the adjusting ring 130 in a direction that causes the adjusting ring 130 to move downward.

[0070] The second elastic element 160 is a spring, and the pressure rod 110 passes through the second elastic element 160.

[0071] The second elastic element 160 is used to press the adjusting ring 130 to prevent the adjusting ring 130 from moving upward due to the child lock piece 140 rebounding when the plug valve 100 enters the second state, which would cause the opening 141 of the child lock piece 140 to be unable to be fitted onto the second limit block 131, thus preventing the second state from being switched stably.

[0072] In this embodiment, the plug valve 100 also includes a knob 170, which is sleeved on the top of the pressure rod 110, and the lower surface of the knob 170 abuts against the second elastic member 160.

[0073] The knob 170 is fitted on the top of the pressure rod 110, increasing the volume of the upper part of the pressure rod 110 and making it easier for the user to rotate the pressure rod 110. The lower surface of the knob abuts against the second elastic element 160. When the knob 170 is pressed, the second elastic element 160 can be indirectly compressed, giving the adjusting ring 130 a downward force, preventing the adjusting ring 130 from moving upward due to the child lock piece 140 rebounding when the plug valve 100 enters the second state.

[0074] In this embodiment, an operating wall 132 is provided circumferentially on the adjusting ring 130. The operating wall 132 is located on the outer periphery of the knob 170, and the knob 170 and the second elastic member 160 are located on the inner side of the operating wall 132.

[0075] The operating wall 132 is located on the outer periphery of the knob 170, allowing the user to lift the adjusting ring 130 when switching to the second state, so that the second limit block 131 disengages from the opening 141 of the child lock piece 140, thereby unlocking the second state. The knob 170 and the second elastic element 160 are located inside the operating wall 132, which hides the spring at the bottom of the knob 170 and has an aesthetic effect.

[0076] In this embodiment, the pressure plate 120 has a through hole 122, and the second limiting block 131 is inserted into the through hole 122.

[0077] The adjusting ring 130 is located on the upper side of the pressure plate 120, and the child lock piece 140 is located on the lower side of the pressure plate 120. A through hole 122 is provided on the pressure plate 120 so that the limiting block protruding downward on the adjusting ring 130 can contact the child lock piece 140, which facilitates state switching.

[0078] In this embodiment, in the first state, the second limiting block 131 abuts against the upper surface of the child lock piece 140.

[0079] In the first state, the opening 141 of the child lock piece 140 is fitted onto the first limiting block 121. Since the second limiting block 131 abuts against the upper surface of the child lock piece 140, the child lock piece 140 cannot move upward, thus achieving the locking in the first state.

[0080] In this embodiment, in the second state, the first limiting block 121 abuts against the upper surface of the child lock piece 140.

[0081] In the second state, the opening 141 of the child lock piece 140 is fitted onto the second limiting block 131. Since the first limiting block 121 abuts against the upper surface of the child lock piece 140, the child lock piece 140 cannot move upward, thus achieving the locking in the second state.

[0082] like Figure 2 As shown, in this embodiment, the pressure rod 110 includes a pressure plate 111, and the side wall of the pressure rod 110 is provided with a mounting groove 112, and the pressure plate 111 is located in the mounting groove 112.

[0083] The pressure rod 110 needs to be able to move the child lock piece 140 downward when it is pressed to unlock. The mounting groove 112 is opened on the side wall of the pressure rod 110 and a pressure piece 111 is installed so that the pressure piece 111 forms a horizontal contact surface with the pressure rod 110 and the child lock piece 140 respectively. When the pressure rod 110 is pressed, the pressure rod 110 moves the pressure piece 111 downward, and the pressure piece 111 then moves the child lock piece 140 downward.

[0084] In this embodiment, the child lock plate 140 is provided with a sleeve hole 142, and the pressure rod 110 passes through the sleeve hole 142. The side wall of the sleeve hole 142 has a limiting surface 143, which is used to prevent the pressure rod 110 from rotating freely in the sleeve hole 142.

[0085] The pressure rod 110 needs to be able to rotate and drive the child lock plate 140 to rotate to achieve the switching between the first state and the second state. A sleeve hole 142 is provided on the child lock plate 140, and the side wall of the sleeve hole 142 is a limiting surface 143. The limiting surface 143 is used to prevent the pressure rod 110 from rotating freely in the sleeve hole 142, so that the child lock plate 140 can rotate when the pressure rod 110 rotates.

[0086] In this embodiment, the first state is the initial unlit state. If the user needs to turn on the stove, they need to press the knob 170 to drive the opening 141 of the child lock piece 140 downward to disengage from the first limiting block 121. Then, rotate the knob 170. After rotating 170°, the opening 141 of the child lock piece 140 reaches the position corresponding to the second limiting block 131. If there is no pressing force, the child lock piece 140 is pushed upward by the first elastic element 150 to make the opening 141 fit into the second limiting block 131, reaching the second state. If the user needs to adjust the fire, they need to grasp the operating wall 132 and apply force to lift the adjusting ring 130, so that the second limiting block 131 disengages from the opening 141 of the child lock piece 140. Then, rotate the knob 170 to disengage from the second state.

[0087] This embodiment also provides a stove, including the above-described stopcock valve 100.
