Description

Technical Field

[0001] The invention relates to a manual-automatic integrated valve. Background Art

[0002] The existing stove valve bodies only have pure manual valves and pure electric valves, and the manual valve and the electric valve cannot be switched. The stove with a manual valve can only adjust the firepower by the user at close range when in use, while the stove with an electric valve can remotely control the firepower of the stove when in use. However, since the stove is used in a high temperature, high humidity and high oil environment, the electric valve is easily damaged during use, which affects the user's normal cooking and is not convenient for maintenance and installation. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a manual-automatic valve, aiming to provide an ultra-thin manual-automatic valve body, which solves the problem of combining a manual valve and an electric valve and is convenient for maintenance and installation.

[0004] In order to achieve the above object, the present invention adopts the following scheme:

[0005] A manual-automatic valve comprises a detachably connected stove valve body and an automatic clutch transmission box, wherein the automatic clutch transmission box is provided with a motor, a clutch, a driving gear and a driven gear, wherein the clutch enables the motor and the driving gear to be reliably combined or completely separated, wherein the stove valve body is provided with a valve stem, wherein a valve stem gear is provided on the valve stem, wherein the valve stem gear is meshed with the driven gear, and when the motor and the driving gear are combined, the motor drives the driving gear to rotate through the clutch, thereby driving the driven gear to rotate, thereby driving the valve stem gear and the valve stem to rotate to adjust the firepower, and when the motor and the driving gear are completely separated, the user manually controls the valve stem to rotate, thereby adjusting the firepower of the stove, and the user can manually control ... The disassembled stove valve body and automatic clutch transmission box are easy to disassemble and repair. The electric automatic clutch transmission box part realizes the combination of manual and automatic valve bodies and can switch automatically, realizing the coexistence of manual close-range control and automatic long-range control. It is an innovative new product. The clutch is used in the automatic clutch transmission box to enable the motor and the driving gear to be combined and completely separated. When the valve stem is manually controlled, the rotation of the valve stem is not affected by the motor because the motor and the driving gear are completely separated. When electrically controlled, the motor and the driving gear are combined so that the motor controls the rotation of the valve stem and the valve core through the driving gear, the driven gear, the valve stem gear, and the valve core gear in turn to control the firepower.

[0006] In one or more embodiments, the clutch is provided with a power clutch disc, a cam disc, a return spring and a non-rotating power sleeve, the cam disc and the power clutch disc are sequentially arranged on the motor shaft, the power sleeve is sleeved on the power clutch disc, the cam disc drives the power sleeve to move in the direction of the driving gear and then pushes the power clutch disc to move in the direction of the driving gear, the return spring resets the power clutch disc and the power sleeve, and a clutch is formed by the power clutch disc, the cam disc, the return spring and the non-rotating power sleeve, and the motor and the driving gear are combined and completely separated through the clutch.

[0007] In one or more embodiments, rollers protruding toward the cam disc are symmetrically arranged on the power sleeve, and the cam disc is provided with multiple protrusions on one side surface of the power clutch disc. The cam disc rotates around the motor shaft so that the protrusions touch the power sleeve at intervals, thereby pushing the power clutch disc to move in the direction of the driving gear so that the power clutch disc and the driving gear are combined, and the driving motor drives the power clutch disc to rotate, thereby driving the driving gear to rotate.

[0008] In one or more embodiments, a plurality of protrusions are provided on the power clutch disk on one side of the driving gear, and a plurality of grooves matching with the protrusions are provided on the driving gear. When the power clutch disk moves toward the driving gear so that the protrusions are inserted into the grooves, the power clutch disk drives the driving gear to rotate under the drive of the motor. At the moment when the power clutch disk is combined with the driving gear, the power clutch disk drives the driving gear to rotate under the drive of the motor. At the moment when the plurality of power clutch disks are combined with the driving gear, the driving gear rotates continuously. At the same time, by providing a plurality of protrusions on the cam disk, the protrusions on the power clutch disk and the grooves of the driving gear, the driving gear is decelerated relative to the motor.

[0009] In one or more embodiments, the stove valve body is a plug valve or an ultra-thin valve body.

[0010] In one or more embodiments, the ultra-thin valve body is provided with a valve stem, a valve core, a valve body and a solenoid valve, the valve body is provided with a connected solenoid valve installation cavity and a valve core cavity, the solenoid valve is arranged in the solenoid valve installation cavity, the valve core is arranged in the valve core cavity, the valve stem is arranged along the Y-axis, the valve core is arranged along the X-axis, the valve stem drives the valve core to rotate, the solenoid valve installation cavity is connected to the air inlet, and the valve core cavity is connected to multiple air outlets. The valve stem and the valve core of the valve body are arranged through the Y-axis and the X-axis so that the valve core is changed from the traditional vertical arrangement to the horizontal arrangement, which greatly reduces the height of the valve body and reduces the height of the valve body, thereby improving the basic technical support for the realization of ultra-thin stoves.

[0011] In one or more embodiments, the valve stem gear is a bevel gear and is disposed at the lower portion of the valve stem, a bevel valve core gear is disposed on the valve core, and the valve stem gear is meshed with the valve core gear.

[0012] In one or more embodiments, the valve body is provided with two air outlets and one vent, and the vent is selectively connected to the valve core cavity. When the stove is a three-ring stove, the vent is connected to the valve core cavity. When the stove is a two-ring stove, the vent is not connected to the valve core cavity. The vent can also be connected to the solenoid valve installation cavity. When the vent is connected to the solenoid valve installation cavity, the air inlet is blocked.

[0013] In one or more embodiments, when the stove valve body is a plug valve, the valve stem and the valve core are arranged in a vertical direction, and the valve stem gear is located at the lower part of the valve stem and meshes with the driven gear.

[0014] In one or more embodiments, an angle measuring device for measuring the rotation angle of the valve stem is provided on the valve stem. The angle measuring device is an encoder. The encoder is a sensor that directly outputs digital quantities. A fixed digital code corresponding to the position can be read at any position of the rotating shaft. The photoelectric conversion is performed using natural binary or cyclic binary (Gray code). The absolute value of the valve stem angle coordinate can be directly read.

[0015] The valve stem of the stove is rotated synchronously with the rotary encoder fixed on the valve stem. When the valve stem is rotated to change the firepower synchronously, the rotary encoder outputs corresponding pulse changes, and the incremental encoder can output the incremental changes of the encoder from the predefined starting position. The pulses are counted through PLC, counter or inverter, and the pulse data is converted into speed or motion data, while the absolute encoder can generate a digital signal that can identify the absolute position. The absolute encoder can read the coordinate position of the valve stem of the gas stove most accurately, output the valve stem position and firepower, and control the motor rotation through PLC to achieve firepower adjustment.

[0016] It has strong anti-interference ability in angle measurement and displacement measurement, and has a stable and reliable output pulse signal, and the pulse signal can be counted to obtain the measured digital signal. The output resolution is 360 pulses / circle.

[0017] Working principle of automatic clutch transmission box:

[0018] When automatic:

[0019] The motor drives the cam plate, the power sleeve and the power clutch plate to rotate. When the cam plate rotates, the convex part drives the power sleeve and the power clutch plate to move in the direction of the driving gear so that the convex part of the power clutch plate enters the concave part of the driving gear. The rotation of the power clutch plate drives the driving gear to rotate and then drives the driven gear to rotate. After the convex part and the roller are separated, the power sleeve and the power clutch plate are reset under the action of the reset spring and the power clutch plate leaves the driving gear. The power sleeve and the power clutch plate reciprocate in sequence and drive the driving gear to rotate.

[0020] Manually:

[0021] When the motor stops moving, the valve stem drives the driven gear and the driving gear to move through the gears. Since the power sleeve and the power clutch plate are separated from the driving gear, the rotation of the driving gear does not affect the power sleeve, the power clutch plate, the cam plate and the motor to remain stationary.

[0022] Beneficial effects: The present invention provides a manual-automatic integrated valve, which is convenient for disassembly and maintenance of the electric automatic clutch transmission box part through the detachable stove valve body and the automatic clutch transmission box, realizes the combination of manual and automatic valve bodies and automatic switching, and realizes the coexistence of manual short-distance control and automatic long-distance control. It is an innovative new product. A clutch is used in the automatic clutch transmission box to enable the motor and the driving gear to be combined and completely separated. When the valve stem is manually controlled, the rotation of the valve stem is not affected by the motor because the motor and the driving gear are completely separated. When electrically controlled, the motor and the driving gear are combined so that the motor controls the rotation of the valve stem and the rotation of the valve core through the driving gear, the driven gear, the valve stem gear, and the valve core gear in turn to control the firepower.
