Description

Technical Field

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

[0002] The fire power of most gas stoves can be adjusted by turning a knob. When turning the knob, misoperation often occurs, causing the fire power to suddenly increase.

[0003] In order to prevent misoperation, 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 pressed down and turned, the rotation restriction of the gas stove knob by the limit structure can be released. However, the position sense of the gas stove knob is poor when the gas stove knob is pressed down and turned, and misoperation still occurs. Utility Model Content

[0032] In the process that the valve stem 6 drives the rotating disk body 4 to rotate around the axis of the valve stem 6, when the bead 3 contacts the side wall of the rotating disk body 4 (not at the position of the gear slot 41), the side wall of the rotating disk body 4 (not at the position of the gear slot 41) presses the bead 3 and the spring piece 2 toward the outside of the rotating disk body 4, and the rotating disk body 4 can rotate smoothly. As the rotating disk body 4 rotates, when the bead 3 rotates to a position opposite to the gear slot 41, the side wall of the rotating disk body 4 (not at the position of the gear slot 41) no longer presses toward the rotating disk body 4. The outside of the rotating disk body 4 squeezes the bead 3 and the spring piece 2, and the bead 3 bounces into the gear slot 41 under the elastic force of the spring piece 2, thereby generating vibration and sound, and feedbacking the gear effect through tactile and auditory sense to form a gear sense; continue to rotate the rotating disk body 4, the bead 3 contacts the side wall of the rotating disk body 4 (not in the gear slot 41 position) again, and the side wall of the rotating disk body 4 (not in the gear slot 41 position) squeezes the bead 3 and the spring piece 2 toward the outside of the rotating disk body 4, and the rotating disk body 4 can rotate smoothly.

[0033] The side wall of the rotating disk 4 is provided with a plurality of gear slots 41, which are arranged at intervals along the circumference of the rotating disk 4. When the rotating disk 4 rotates, as the rotation angle of the rotating disk 4 changes, the beads 3 can be ejected into different gear slots 41 to prompt the user of different gear changes. When the valve stem 6 rotates, the firepower can be adjusted. During the process of adjusting the firepower, the beads 3 can be ejected into different gear slots 41, producing an obvious gear sense, prompting the user of different gear changes, and reducing the probability of user misoperation.

[0034] In order to install the ball body 3 and the spring piece 2 on the outside of the rotating disk body 4, in an optional implementation, one end of the spring piece 2 away from the ball body 3 is fixed to the gear valve assembly, and the end of the spring piece 2 that contacts the ball body 3 is fixed to the ball body 3, thereby installing the ball body 3 and the spring piece 2 at a suitable position outside the rotating disk body 4.

[0035] Preferably, the shift valve assembly also includes an upper cover plate 5; the upper cover plate 5 is provided with a rotating disk body mounting groove 51, and the side wall of the rotating disk body mounting groove 51 is provided with a clamping groove 511, and the two ends of the clamping groove 511 are respectively penetrated with the side wall of the rotating disk body mounting groove 51; the valve stem 6 passes through the bottom wall of the rotating disk body mounting groove 51; the rotating disk body 4 is arranged in the rotating disk body mounting groove 51; the bead body 3 is arranged in the clamping groove 511, the bead body 3 can move along the extension direction of the clamping groove 511, and the bead body 3 can be clamped with the clamping groove 511 toward one end opening of the rotating disk body 4.

[0036] Specifically, a rotating disc body installation groove 51 is provided on the top wall of the upper cover plate 5, and the valve stem 6 passes through the bottom wall of the rotating disc body installation groove 51, and the valve stem 6 can rotate relative to the rotating disc body installation groove 51 around the axis of the valve stem 6; the rotating disc body 4 is provided with a connecting hole 42, and the rotating disc body 4 is fixedly sleeved on the valve stem 6 through the connecting hole 42. When the valve stem 6 rotates around the axis of the valve stem 6, the valve stem 6 can drive the rotating disc body 4 to rotate relative to the rotating disc body installation groove 51 around the axis of the valve stem 6. When the valve stem 6 rotates relative to the rotating disc body installation groove 51 around the axis of the valve stem 6, the firepower of the gas stove can be adjusted.

[0037] The bead 3 is arranged in the slot 511, and the bead 3 can move along the extending direction of the slot 511, so that the bead 3 can move toward the rotating disk 4 along the extending direction of the slot 511, so that the bead 3 protrudes from the inner surface of the side wall, and the bead 3 can also move away from the rotating disk 4 along the extending direction of the slot 511, so that the bead 3 does not protrude from the inner surface of the side wall. The bead 3 can be engaged with the end opening of the slot 511 facing the rotating disk 4, so as to prevent the bead 3 from falling off from the end opening of the slot 511 facing the rotating disk 4.

[0038] In the process that the valve stem 6 drives the rotating disk body 4 to rotate around the axis of the valve stem 6 relative to the rotating disk body mounting groove 51, when the bead body 3 contacts the side wall of the rotating disk body 4 (not at the position of the gear groove 41), the side wall of the rotating disk body 4 (not at the position of the gear groove 41) squeezes the bead body 3 and the spring piece 2 toward the outside of the rotating disk body mounting groove 51, and the bead body 3 does not protrude from the inner surface of the side wall, so that the rotating disk body 4 can smoothly rotate relative to the rotating disk body mounting groove 51. As the rotating disk body 4 rotates, when the bead body 3 rotates to a position opposite to the gear groove 41, the side wall of the rotating disk body 4 (not at the position of the gear groove 41) no longer squeezes the rotating disk body mounting groove 51. The bead 3 and the spring piece 2 are pressed, and under the elastic force of the spring piece 2, the bead 3 moves toward the rotating disk body 4 along the extension direction of the slot 511, so that the bead 3 bounces into the gear slot 41, thereby generating vibration and sound, and forming a gear sense through tactile and auditory feedback of the gear effect; the rotating disk body 4 continues to rotate, and the bead 3 contacts the side wall of the rotating disk body 4 (not in the gear slot 41 position) again, and the side wall of the rotating disk body 4 (not in the gear slot 41 position) squeezes the bead 3 and the spring piece 2 toward the outside of the rotating disk body mounting slot 51, and the bead 3 does not protrude from the inner surface of the side wall, so that the rotating disk body 4 can rotate smoothly relative to the rotating disk body mounting slot 51.

[0039] The side wall of the rotating disk 4 is provided with a plurality of gear slots 41, and the plurality of gear slots 41 are arranged at intervals along the circumference of the rotating disk 4. When the rotating disk 4 rotates in the rotating disk installation slot 51, as the rotation angle of the rotating disk 4 changes, the bead 3 can be bounced into different gear slots 41 to prompt the user of different gear changes. When the valve stem 6 rotates, the firepower can be adjusted. During the process of adjusting the firepower, the bead 3 can be bounced into different gear slots 41, producing an obvious gear sense, to prompt the user of different gear changes, and reduce the probability of the user making a wrong operation.

[0040] The spring piece 2 can be installed in the card slot 511 or outside the card slot 511. For example, when the spring piece 2 is installed in the card slot 511, the spring piece 2 is arranged at one end of the card slot 511 away from the rotating disk body 4, one end of the spring piece 2 is fixedly connected to the side wall of the card slot 511, and the other end of the spring piece 2 is spaced from the other side wall of the card slot 511.

[0041] Preferably, the upper cover plate 5 is further provided with an elastic piece installation groove 52 , and the elastic piece installation groove 52 is sleeved on the outside of the rotating disk body installation groove 51 ; the elastic piece 2 is arranged in the elastic piece installation groove 52 .

[0042] The top wall of the upper cover plate 5 is also provided with an elastic piece installation groove 52, which is arranged around the outer side of the rotating disk body installation groove 51. The elastic piece 2 is arranged in the elastic piece installation groove 52, and the elastic piece 2 contacts the ball through the end opening of the slot 511 away from the rotating disk body 4.

[0043] The spring piece 2 has a long stroke and can provide a stable elastic force in a large range, thereby preventing the elastic force change from causing a difference in gear position feeling.

[0044] The spring piece 2 needs to be fixed in the spring piece installation groove 52 , and the connection method can be a fixed connection, such as bonding or welding, or a detachable connection, such as a snap connection or a threaded connection.

[0045] Preferably, the spring piece 2 is snap-fitted with the spring piece mounting groove 52 .

[0046] A clamping groove is provided in the spring piece installation groove 52 , and the spring piece 2 is clamped with the clamping groove, so that the spring piece 2 is clamped with the spring piece installation groove 52 , which can facilitate the disassembly and assembly of the spring piece 2 and the spring piece installation groove 52 .

[0047] Furthermore, the outer contour of the spring piece 2 is arc-shaped.

[0048] Since the outer contour of the spring piece 2 is arc-shaped, it can be better ensured that the spring piece 2 is installed on the upper cover plate 5, and then the overall structure of the rotating disk body 4, the spring piece 2 and the bead body 3 can be installed on the upper cover plate 5.

[0049] Furthermore, the shift valve assembly further comprises a baffle plate 1 ; the baffle plate 1 is sleeved on the valve stem 6 , and the baffle plate 1 covers the opening of the spring piece mounting groove 52 , and the baffle plate 1 is connected to the upper cover plate 5 .

[0050] Specifically, the baffle 1 is sleeved on the valve stem 6, and the valve stem 6 can rotate relative to the baffle 1 around the axis of the valve stem 6. The baffle 1 covers the opening of the spring installation groove 52 and the opening of the rotating disk installation groove 51, thereby enclosing the rotating disk 4, the spring 2 and the bead 3 between the spring installation groove 52, the rotating disk installation groove 51 and the baffle 1, and protecting the rotating disk 4, the spring 2 and the bead 3. The baffle 1 is fixed to the upper cover plate 5, so that the baffle 1 and the upper cover plate 5 are connected as a whole.

[0051] Furthermore, a sleeve 12 is provided on the top surface of the baffle 1 , and the sleeve 12 is sleeved on the valve stem 6 ; the sleeve 12 is fitted to the valve stem 6 , and the valve stem 6 can rotate relative to the sleeve 12 around the axis of the valve stem 6 .

[0052] The sleeve 12 is fitted with the valve stem 6, which can increase the matching surface between the baffle 1 and the valve stem 6, reduce the shaking of the valve stem 6, and improve the user experience. When the valve stem 6 rotates around the axis of the valve stem 6, the baffle 1 and the sleeve 12 are fixed on the upper cover plate 5, and the baffle 1 and the sleeve 12 do not rotate with the valve stem 6.

[0053] The sleeve 12 may be fixedly connected to the baffle 1 or may be an integrally formed structure.

[0054] Preferably, the sleeve 12 and the baffle 1 are an integrally formed structure.

[0055] The sleeve 12 and the baffle 1 are integrally formed, so that the structural strength of the sleeve 12 and the baffle 1 is high and the difficulty of assembly is reduced.

[0056] For example, the baffle plate 1 is provided with a through hole 11 , and the baffle plate 1 is sleeved on the valve stem 6 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 12 .

[0057] Furthermore, the baffle plate 1 is detachably connected to the upper cover plate 5 .

[0058] The baffle plate 1 and the upper cover plate 5 may be connected in a threaded connection or in any other suitable manner such as a clamping connection.

[0059] The baffle 1 is detachably connected to the upper cover plate 5. When the gear sense fails and the rotating disk 4, the spring 2 or the bead 3 and other parts need to be replaced, it is only necessary to disassemble the baffle 1 to replace the damaged parts inside the rotating disk mounting groove 51 and the spring mounting groove 52. It 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.

[0060] Furthermore, the baffle plate 1 is detachably connected to the upper cover plate 5 via a fastener 7 .

[0061] The fastener 7 may be any suitable component such as a screw or a bolt. The baffle 1 is connected to the upper cover plate 5 by the fastener 7. The connection has high stability and is easy to operate.

[0062] In this embodiment, the baffle plate 1 is connected to the upper cover plate 5 by fasteners 7 on both sides of the baffle plate 1 , so that the baffle plate 1 can be firmly fixed on the upper cover plate 5 .

[0063] In addition, the baffle plate 1 may also be connected to the 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 baffle plate 1 .

[0064] Example 2

[0065] The gas stove provided in this embodiment includes the gear valve assembly provided in Embodiment 1. In the process that the valve stem 6 drives the rotating disc 4 to rotate around the axis of the valve stem 6, when the bead 3 contacts the side wall of the rotating disc 4 (not at the gear slot 41 position), the side wall of the rotating disc 4 (not at the gear slot 41 position) presses the bead 3 and the spring piece 2 toward the outside of the rotating disc 4, and the rotating disc 4 can rotate smoothly. As the rotating disc 4 rotates, when the bead 3 rotates to a position opposite to the gear slot 41, the side wall of the rotating disc 4 (not at the gear slot 41 position) no longer presses toward the rotating disc 4. The outside of the rotating disk body 4 squeezes the bead 3 and the spring piece 2, and the bead 3 bounces into the gear slot 41 under the elastic force of the spring piece 2, thereby generating vibration and sound, and feedbacking the gear effect through tactile and auditory sense to form a gear sense; continue to rotate the rotating disk body 4, the bead 3 contacts the side wall of the rotating disk body 4 (not in the gear slot 41 position) again, and the side wall of the rotating disk body 4 (not in the gear slot 41 position) squeezes the bead 3 and the spring piece 2 toward the outside of the rotating disk body 4, and the rotating disk body 4 can rotate smoothly.

[0066] The side wall of the rotating disk 4 is provided with a plurality of gear slots 41, which are arranged at intervals along the circumference of the rotating disk 4. When the rotating disk 4 rotates, as the rotation angle of the rotating disk 4 changes, the beads 3 can be ejected into different gear slots 41 to prompt the user of different gear changes. When the valve stem 6 rotates, the firepower can be adjusted. During the process of adjusting the firepower, the beads 3 can be ejected into different gear slots 41, producing an obvious gear sense, prompting the user of different gear changes, and reducing the probability of user misoperation.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
