[0031] When the valve stem 7 drives the disk 4 to rotate around the axis of the valve stem 7, when the bead 3 contacts the side wall of the disk 4 (non-gear groove 42 position), the side wall of the disk 4 (non-gear groove 42 position) squeezes the bead 3 and the spring 2 toward the outside of the disk 4, and the disk 4 can rotate smoothly. As the disk 4 rotates, when the bead 3 rotates to a position opposite to the gear groove 42, the side wall of the disk 4 (non-gear groove 42 position) no longer squeezes the bead 3 and the spring 2 toward the outside of the disk 4, and the bead 3 bounces into the gear groove 42 under the elastic force of the spring 2, thereby generating vibration and sound, and feedbacks the gear effect through tactile and auditory sense to form a gear sense; continue to rotate the disk 4, the bead 3 contacts the side wall of the disk 4 (non-gear groove 42 position) again, and the side wall of the disk 4 (non-gear groove 42 position) squeezes the bead 3 and the spring 2 toward the outside of the disk 4, and the disk 4 can rotate smoothly.
[0032] The side wall of the disc 4 is provided with a plurality of gear grooves 42, which are arranged at intervals along the circumference of the disc 4. When the disc 4 rotates in the disc accommodating groove 51, as the rotation angle of the disc 4 changes, the bead 3 can bounce into different gear grooves 42 to prompt the user of different gear changes. When the valve stem 7 rotates, the firepower can be adjusted. During the process of adjusting the firepower, the bead 3 can bounce into different gear grooves 42 to produce an obvious gear sense, to prompt the user of different gear changes, and reduce the probability of user misoperation.
[0033] Furthermore, the shift valve device also includes a top plate 5; the top surface of the top plate 5 is provided with a disc-shaped member receiving groove 51 and a mounting groove 52, and one end of the mounting groove 52 is connected to the side wall of the disc-shaped member receiving groove 51; the valve stem 7 passes through the bottom wall of the disc-shaped member receiving groove 51; the disc-shaped member 4 is arranged in the disc-shaped member receiving groove 51; the bead 3 and the spring 2 are arranged in the mounting groove 52; the bead 3 can move along the extension direction of the mounting groove 52, and the bead 3 can be clamped with the end of the mounting groove 52 toward the disc-shaped member receiving groove 51.
[0034] Specifically, a disc-shaped member receiving groove 51 is provided on the top surface of the top plate 5, and the valve stem 7 passes through the bottom wall of the disc-shaped member receiving groove 51, and the valve stem 7 can rotate relative to the disc-shaped member receiving groove 51 around the axis of the valve stem 7; the disc-shaped member 4 is provided with a connecting hole 41, and the disc-shaped member 4 is fixedly sleeved on the valve stem 7 through the connecting hole 41, and when the valve stem 7 rotates around the axis of the valve stem 7, the valve stem 7 can drive the disc-shaped member 4 to rotate relative to the disc-shaped member receiving groove 51 around the axis of the valve stem 7. When the valve stem 7 rotates relative to the disc-shaped member receiving groove 51 around the axis of the valve stem 7, the firepower of the stove can be adjusted.
[0035] The bead 3 is disposed in the mounting groove 52, and the bead 3 can move along the extension direction of the mounting groove 52, so that the bead 3 can move toward the disc 4 along the extension direction of the mounting groove 52, so that the bead 3 protrudes from the inner surface of the side wall of the disc receiving groove 51, and the bead 3 can also move away from the disc 4 along the extension direction of the mounting groove 52, so that the bead 3 does not protrude from the inner surface of the side wall of the disc receiving groove 51. The bead 3 can be engaged with the end opening of the mounting groove 52 toward the disc receiving groove 51, so as to prevent the bead 3 from falling off from the mounting groove 52 toward the end opening of the disc receiving groove 51.
[0036] In the process that the valve stem 7 drives the disc 4 to rotate around the axis of the valve stem 7 relative to the disc accommodating groove 51, when the bead 3 contacts the side wall of the disc 4 (the position of the non-gear groove 42), the side wall of the disc 4 (the position of the non-gear groove 42) presses the bead 3 and the spring 2 toward the outside of the disc accommodating groove 51, and the bead 3 does not protrude from the inner surface of the side wall of the disc accommodating groove 51, so that the disc 4 can rotate smoothly relative to the disc accommodating groove 51. As the disc 4 rotates, when the bead 3 rotates to a position opposite to the gear groove 42, the side wall of the disc 4 (the position of the non-gear groove 42) no longer presses toward the outside of the disc accommodating groove 51. The bead 3 and the spring 2, under the elastic force of the spring 2, the bead 3 moves toward the disc 4 along the extension direction of the installation groove 52, so that the bead 3 bounces into the gear groove 42, thereby generating vibration and sound, and forming a gear sense through tactile and auditory feedback of the gear effect; the disc 4 continues to rotate, and the bead 3 contacts the side wall of the disc 4 (not the gear groove 42 position) again, and the side wall of the disc 4 (not the gear groove 42 position) squeezes the bead 3 and the spring 2 toward the outside of the disc accommodating groove 51, and the bead 3 does not protrude from the inner surface of the side wall of the disc accommodating groove 51, so that the disc 4 can rotate smoothly relative to the disc accommodating groove 51.

[0039] Preferably, one end of the spring 2 away from the bead 3 is engaged with the mounting groove 52 .
[0040] One end of the spring 2 away from the bead 3 is engaged with the mounting groove 52 , which makes it easy to disassemble and assemble the spring 2 and the mounting groove 52 .
[0041] Furthermore, the shift valve device further comprises a cover plate 1 ; the cover plate 1 is sleeved on the valve stem 7 , and the cover plate 1 is connected to the top plate 5 , so that the cover plate 1 covers the opening of the disc-shaped member receiving groove 51 and the opening of the mounting groove 52 .
[0042] Specifically, the cover plate 1 is sleeved on the valve stem 7, and the valve stem 7 can rotate relative to the cover plate 1 around the axis of the valve stem 7. The cover plate 1 covers the opening of the spring 2 installation groove 52 and the opening of the disc-shaped member receiving groove 51, thereby enclosing the disc-shaped member 4, the spring 2 and the bead 3 between the spring 2 installation groove 52, the disc-shaped member receiving groove 51 and the cover plate 1, thereby protecting the disc-shaped member 4, the spring 2 and the bead 3. The cover plate 1 is fixed to the top plate 5, thereby connecting the cover plate 1 and the top plate 5 as a whole.
[0043] Furthermore, a cylinder 12 is provided on the top surface of the cover plate 1 , and the cylinder 12 is sleeved on the valve stem 7 ; the cylinder 12 and the valve stem 7 are arranged in close contact, and the valve stem 7 can rotate relative to the cylinder 12 around the axis of the valve stem 7 .
[0044] The cylinder 12 is fitted with the valve stem 7, which can increase the matching surface between the cover plate 1 and the valve stem 7, reduce the shaking 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 cover plate 1 and the cylinder 12 are fixed on the top plate 5, and the cover plate 1 and the cylinder 12 do not rotate with the valve stem 7.
[0045] The cylinder 12 may be fixedly connected to the cover plate 1 or may be an integral structure.
[0046] Preferably, the cylinder 12 and the cover plate 1 are an integrated structure.
[0047] The cylinder 12 and the cover plate 1 are an integrated structure, so that the structural strength of the cylinder 12 and the cover plate 1 is higher and the difficulty of assembly is reduced.
[0048] For example, the cover plate 1 is provided with a through hole 11 , and the cover plate 1 is sleeved on the valve stem 7 through the through hole 11 . An upper flange structure is provided on the edge of the through hole 11 , so that the upper flange structure forms a cylinder 12 .
[0049] Furthermore, the cover plate 1 is detachably connected to the top plate 5 .
[0050] The connection between the cover plate 1 and the top plate 5 may be threaded connection, or may be clamped or any other suitable connection.
[0051] The cover plate 1 is detachably connected to the top plate 5. When the gear sense fails and parts such as the disc 4, spring 2 or bead 3 need to be replaced, it is only necessary to disassemble the cover plate 1 to replace the damaged parts inside the disc accommodating groove 51 and the spring 2 mounting groove 52. This does not involve the disassembly and assembly of the valve body or the airtight parts of the valve body. The installation is reliable and the replacement is convenient.
[0052] Furthermore, the cover plate 1 and the top plate 5 are detachably connected via a fastener 6 .
[0053] The fastener 6 may be any suitable component such as a screw or a bolt. The cover plate 1 is connected to the top plate 5 by the fastener 6, and the connection has high stability and is easy to operate.
[0054] In this embodiment, the cover plate 1 is connected to the top plate 5 by fasteners 6 on both sides of the cover plate 1 , so that the cover plate 1 can be firmly fixed on the top plate 5 .
[0055] In addition, the cover plate 1 may also be connected to the top 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 cover plate 1 .

As the disk 4 rotates, when the bead 3 rotates to a position opposite to the gear groove 42, the side wall of the disk 4 (non-gear groove 42 position) no longer squeezes the bead 3 and the spring 2 toward the outside of the disk 4, and the bead 3 bounces into the gear groove 42 under the elastic force of the spring 2, thereby generating vibration and sound, and feedbacks the gear effect through tactile and auditory sense to form a gear sense; continue to rotate the disk 4, the bead 3 contacts the side wall of the disk 4 (non-gear groove 42 position) again, and the side wall of the disk 4 (non-gear groove 42 position) squeezes the bead 3 and the spring 2 toward the outside of the disk 4, and the disk 4 can rotate smoothly.
[0058] The side wall of the disc 4 is provided with a plurality of gear grooves 42, which are arranged at intervals along the circumference of the disc 4.
