Description

Technical Field

[0001] The utility model relates to the technical field of flow control valves, in particular to a novel gas valve flow controller. Background Art

[0002] A gas control valve has functions such as opening and closing gas and controlling flow, enabling the opening and closing of gas pathways and controlling the size of the combustion flame. A Chinese invention patent application, publication number CN113394043A, discloses a gas appliance knob capable of both electronic and manual rotation. The fixture of the gas appliance is located outside the housing of a position detector in the electronic control system. The housing of the position detector houses a bushing that is positioned around the periphery of the gas valve shaft and deflects in conjunction with the shaft. The bushing is provided with a synchronously deflecting annular magnet, and the housing is provided with at least one magnetic sensing element on the outer side of the annular magnet. This technical solution uses a magnetic sensing element to sense the deflection angle of the annular magnet and transmit the position signal to the electronic control system. While this solution can achieve gas flow control, its structural design is complex and susceptible to interference from external magnetic fields. To address this issue, we propose a new gas valve flow controller. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0017] Combined with attachment Figure 1 To the attached Figure 3As shown, a new type of gas valve flow controller includes a mounting base 10 and a cover plate 30. The cover plate 30 is mounted on the mounting base 10. A rotating member 20 is rotatably arranged between the mounting base 10 and the cover plate 30. A plug hole 23 for connecting to the knob switch of the gas stove is provided in the middle of the rotating member 20. A conductor sheet 60 is provided in the inner annular groove 11 of the mounting base 10. The conductor sheet 60 is specifically integrally injection molded with the mounting base 10 through an embedded injection process.

[0018] As attached Figure 4 As shown, the conductor piece 60 is provided with a potential code piece 40 in the shape of an arc, and the mounting seat 10 is provided with a plug-in terminal 13, which is fixedly installed at the conductor piece 60, and is combined with the attached Figure 2 To the attached Figure 4 As shown, a potential brush 50 is installed on the rotating member 20, and the potential brush 50 slides relatively along the potential code piece 40 to generate a potential signal for controlling the flow of the gas valve.

[0019] Specifically, in conjunction with Figure 2 and attached Figure 3 As shown, the potential brush 50 is installed on the lower side of the rotating member 20, and a limiting protrusion 24 is provided on the upper side of the rotating member 20. A rotation limiting groove 33 corresponding to the potential code piece 40 is opened on the cover 30. The rotation limiting groove 33 is in the shape of an arc and cooperates with the limiting protrusion 24. Figure 3 As shown, the rotation limiting groove 33 is specifically provided with an initial end 331 and an end end 332.

[0020] The rotating member 20 drives the potential brush 50 to rotate. When the limiting protrusion 24 on the rotating member 20 moves to the initial end 331 of the rotation limiting groove 33, the gas valve flow is zero; when the limiting protrusion 24 on the rotating member 20 moves to the rear end 332 of the rotation limiting groove 33, the gas valve flow is maximum.

[0021] Combined with attachment Figure 2 and attached Figure 3 As shown, the rotating member 20 is provided with an upper boss portion 21 and a lower boss portion 22, and a plug-in hole 23 is provided through the upper boss portion 21 and the lower boss portion 22. A first through hole 31 is provided on the cover plate 30 to be plugged into the upper boss portion 21 of the rotating member 20, and a second through hole 12 is provided on the mounting base 10 to be plugged into the lower boss portion 22 of the rotating member 20. A latch portion 14 is provided on the edge of the mounting base 10, and a latch hole 32 is provided on the cover plate 30 to cooperate with the latch portion 14 of the mounting base 10. When the mounting base 10 and the cover plate 30 are engaged, the upper boss portion 21 of the rotating member 20 is inserted into the first through hole 31 of the cover plate 30, and the lower boss portion 22 of the rotating member 20 is inserted into the second through hole 12 of the mounting base 10.

[0022] The utility model generates a potential signal for controlling the flow rate of the gas valve by driving the potential brush 50 to slide relatively along the potential code piece 40 by the rotating part 20, which simplifies the structural design of the gas valve flow control, helps to further reduce the size of the flow controller, and has more diverse control methods. In addition, compared with the existing technology, the utility model will not be interfered with by external magnetic fields.
