Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a gear valve structure and a gas stove. Background Art

[0002] Most gas stove knobs can achieve a higher valve flow rate by turning them. However, if the gas stove knob is turned incorrectly, the firepower will increase sharply.

[0003] To solve the above problems, some gas stove knobs are provided with a limit structure. Specifically, along the rotation direction of the gas knob, the stage valve has a low-load gas interval and a high-load gas interval in sequence. The limit structure corresponds to the setting of the gas knob and is used to limit the rotation of the gas knob from the low-load gas interval to the high-load gas interval; when the gas knob makes a non-rotational motion relative to the limit structure, the limit structure releases the rotation restriction on the gas knob.

[0004] When the gas stove knob is turned toward the high-load gas range, the gas stove knob can be pressed down to rotate to contact the rotation limit of the gas knob by the limit structure. However, the position of the gas stove knob is not obvious when it is pressed down, and the possibility of misoperation is still high. Utility Model Content

[0031] During the process of the valve stem 7 driving the turntable 4 to rotate around the axis of the valve stem 7 relative to the groove, when the marble 3 contacts the side wall of the groove, the side wall of the groove squeezes the marble 3 and the spring 2 into the inside of the turntable 4, and the marble 3 does not protrude from the side wall of the turntable 4, so that the turntable 4 can rotate smoothly relative to the groove. As the turntable 4 rotates, when the marble 3 rotates to a position relative to the gear slot 51, the side wall of the groove no longer squeezes the marble 3 and the spring 2 into the inside of the turntable 4. Under the action of the elastic force of the spring 2, the marble 3 moves toward the outside of the turntable 4 along the extension direction of the slot 43, so that the marble 3 bounces into the gear slot 51 to form a gear sense; continue to rotate the turntable 4, when the marble 3 contacts the side wall of the groove again, the side wall of the groove squeezes the marble 3 and the spring 2 into the inside of the turntable 4, and the marble 3 does not protrude from the side wall of the turntable 4, so that the turntable 4 can rotate smoothly relative to the groove.

[0032] The side wall of the groove is provided with a plurality of gear slots 51, and the plurality of gear slots 51 are arranged at intervals along the circumference of the groove. When the turntable 4 rotates in the groove, as the rotation angle of the turntable 4 changes, the marbles 3 can be bounced into different gear slots 51 to prompt the user of different gear changes. The gear valve structure provided in this embodiment can adjust the firepower when the valve stem 7 rotates. During the process of adjusting the firepower, the marbles 3 can be bounced into different gear slots 51, producing an obvious gear sense, to prompt the user of different gear changes, and reduce the probability of user misoperation.

[0033] Specifically, the side wall of the groove is provided with a plurality of gear grooves 51, and the plurality of gear grooves 51 are arranged at intervals along the circumference of the groove; the valve stem 7 passes through the groove; the turntable 4 is fixedly sleeved on the valve stem 7, and the turntable 4 is arranged in the groove; the side wall of the turntable 4 is provided with a card slot 43, and the opening of the card slot 43 is penetrated by the side wall of the turntable 4; a marble 3 is arranged in the card slot 43, and the marble 3 can move along the extension direction of the card slot 43; a spring piece 2 is provided on the side of the marble 3 away from the opening, and the spring piece 2 is in contact with the marble 3, and the elastic force of the spring piece 2 can drive the marble 3 to bounce into the gear groove 51.

[0034] Specifically, a groove is provided on the top wall of the valve body upper cover plate 5, and the valve stem 7 passes through the bottom wall of the groove, and the valve stem 7 can rotate relative to the groove around the axis of the valve stem 7; the turntable 4 is provided with a positioning hole 41, and the turntable 4 is fixedly sleeved on the valve stem 7 through the positioning hole 41. When the valve stem 7 rotates around the axis of the valve stem 7, the valve stem 7 can drive the turntable 4 to rotate relative to the groove around the axis of the valve stem 7. When the valve stem 7 rotates relative to the groove around the axis of the valve stem 7, the firepower of the gas stove can be adjusted.

[0035] The marble 3 is arranged in the slot 43, and the marble 3 can move along the extension direction of the slot 43, so that the marble 3 can move toward the inside of the turntable 4 along the extension direction of the slot 43, so that the marble 3 does not protrude from the side wall of the turntable 4. The marble 3 can also move toward the outside of the turntable 4 along the extension direction of the slot 43 until the marble 3 is engaged with the opening of the slot 43 and part of the marble 3 protrudes from the side wall of the turntable 4.

[0036] Further, the marble 3 can be engaged with the opening of the slot 43. The marble 3 can be engaged with the opening of the slot 43, which can prevent the marble 3 from falling off the turntable 4.

[0037] The spring sheet 2 can be installed in the card slot 43 or outside the card slot 43. For example, when the spring sheet 2 is installed in the card slot 43, the spring sheet 2 is arranged at one end of the card slot 43 away from the opening of the card slot 43, one end of the spring sheet 2 is fixedly connected to the side wall of the card slot 43, and the other end of the spring sheet 2 is spaced from the other side wall of the card slot 43.

[0038] Preferably, the top wall of the turntable 4 is provided with an elastic sheet installation groove 42 , which is connected to an end of the slot 43 away from the opening; the elastic sheet 2 is arranged in the elastic sheet installation groove 42 , and the outer contour of the elastic sheet 2 is arc-shaped.

[0043] Furthermore, a plurality of shift grooves 51 are evenly spaced along the circumference of the groove.

[0044] The multiple gear slots 51 are evenly spaced along the axial direction of the groove, so that the user can feel the gear position when the valve stem 7 rotates a certain angle. The multiple gear positions are spaced at the same angle, and the adjustment is more convenient.

[0045] Furthermore, the shift valve structure also includes a valve body upper cover plate 5 and a fixed plate 1; a groove is formed on the top of the valve body upper cover plate 5; the fixed plate 1 is sleeved on the valve stem 7, and the fixed plate 1 covers the opening of the groove, and the fixed plate 1 is connected to the valve body upper cover plate 5.

[0046] Specifically, the fixing plate 1 is sleeved on the valve stem 7, and the valve stem 7 can rotate relative to the fixing plate 1 around the axis of the valve stem 7. The fixing plate 1 covers the opening of the groove, thereby enclosing the rotating disk 4, the spring piece 2 and the marble 3 between the groove and the fixing plate 1, and protecting the rotating disk 4, the spring piece 2 and the marble 3. The fixing plate 1 is fixed to the upper cover plate 5 of the valve body, so that the fixing plate 1 and the upper cover plate 5 of the valve body are connected as a whole.

[0047] Furthermore, a sleeve structure 12 is provided on the top surface of the fixing plate 1 , and the sleeve structure 12 is sleeved on the valve stem 7 ; the sleeve structure 12 is arranged in close contact with the valve stem 7 , and the valve stem 7 can rotate relative to the sleeve structure 12 around the axis of the valve stem 7 .

[0048] The sleeve structure 12 is arranged in close contact with the valve stem 7, which can increase the matching surface between the fixed plate 1 and the valve stem 7, reduce the shaking amount of the valve stem 7, and improve the user experience. When the valve stem 7 rotates around the axis of the valve stem 7, the fixed plate 1 and the sleeve structure 12 are fixed on the valve body upper cover plate 5, and the fixed plate 1 and the sleeve structure 12 do not rotate with the valve stem 7.

[0049] The sleeve structure 12 may be fixedly connected to the fixing plate 1 or may be an integral structure.

[0050] Preferably, the sleeve structure 12 and the fixing plate 1 are an integrated structure.

[0051] The sleeve structure 12 and the fixing plate 1 are an integrated structure, so that the structural strength of the sleeve structure 12 and the fixing plate 1 is higher and the difficulty of assembly is reduced.

[0052] For example, a through hole 11 is provided on the fixing plate 1 , and the fixing plate 1 is sleeved on the valve stem 7 through the through hole 11 . An upper flange structure is provided at the position of the through hole 11 , so that the upper flange structure forms a sleeve structure 12 .

[0053] Furthermore, the fixing plate 1 is detachably connected to the valve body upper cover plate 5 .

[0054] The connection between the fixing plate 1 and the valve body upper cover plate 5 may be threaded connection, or may be clamped or any other suitable connection.

[0055] The fixing plate 1 is detachably connected to the upper cover plate 5 of the valve body. When the gear sense fails and parts such as the turntable 4, spring piece 2 or marble 3 need to be replaced, it is only necessary to disassemble the fixing plate 1 to replace the damaged parts inside the groove. It does not involve the disassembly and assembly of the valve body or the airtight parts of the valve body. It is reliable to install and easy to replace.

[0056] Furthermore, the fixing plate 1 is detachably connected to the valve body upper cover plate 5 via a fastener 6 .

[0057] The fastener 6 may be any suitable component such as a screw or a bolt, and the fixing plate 1 is connected to the valve body upper cover plate 5 by the fastener 6. The connection has high stability and is easy to operate.

[0058] Furthermore, two sides of the fixing plate 1 are detachably connected to the valve body upper cover plate 5 via fasteners 6 .

[0059] The fixing plate 1 is connected to the upper cover plate 5 of the valve body by fasteners 6 on both sides of the fixing plate 1 , so that the fixing plate 1 can be firmly fixed on the upper cover plate 5 of the valve body.

[0060] In addition, the fixing plate 1 may also be connected to the valve body upper cover plate 5 via a plurality of connection positions (greater than or equal to three), and the plurality of connection positions are arranged at intervals along the circumference of the fixing plate 1 .
