Technical Field

The invention belongs to the technical field of temperature control valves, and particularly relates to a temperature control valve.

Background

The gas stove is a kitchen utensil heated by direct fire with liquefied petroleum gas (liquid), artificial gas, natural gas and other gas fuels.

After the switch of the gas stove is turned on, sparks are generated, and meanwhile, gas is blown out to be ignited; when wind blows or soup overflows, the flame can be extinguished, and the temperature of the temperature sensor is reduced; the temperature sensor cuts off the gas of the gas stove through the power execution assembly to play a role in flameout protection; however, during ignition, if the battery is not powered and the gas stove does not generate electric spark, the gas can be continuously blown out by pressing the knob switch, and the gas stove cannot be automatically switched off as long as the button is not loosened by hands, so that certain danger exists.

For a commercial multi-hearth gas stove, such as a gas stove used in a snack stall, the firing of each hearth of the gas stove of the hearth needs to be controlled independently, so that the gas stove is very inconvenient to use; it would be very convenient if all cooktops could be controlled to fire simultaneously and the fire size of each cooktop could be adjusted freely.

In the normal anticlockwise rotation shift knob process of igniteing, just rotate after pressing because of shift knob can earlier, shift knob can drive the transmission cover 40 when pressing, the transmission cover 40 moves and drives the third transmission piece 42 of installation on it and removes, make the third transmission piece 42 and the dislocation of fifth transmission piece 50 that originally have the coincidence zone in the circumferential direction, because of under initial condition, during look ahead third transmission piece 42 and fifth transmission piece 50, fourth transmission piece 49 is located the right side of third transmission piece 42, so at the anticlockwise rotation shift knob in-process after pressing shift knob fifth transmission piece 50 because of misplacing with third transmission piece 42, so can not influence the rotation of third transmission piece 42 and can not influence the rotation of transmission cover 40 promptly.

When the switch button is rotated anticlockwise, on one hand, the switch button drives the control rotating shaft 27 at the front end of the first switch valve 6 to rotate through the driving inner rod 36 so as to open the first switch valve 6; on the other hand, the rotation of the switch button can drive the transmission sleeve 40 to rotate, the transmission sleeve 40 drives the electric connecting sheet 46 to rotate through the transmission disc 43, the telescopic inner ring 44, the fourth spring 47 and the telescopic outer sleeve 45, the electric connecting sheet 46 is an annular sheet, and in the process that the transmission sleeve 40 is driven to rotate by the switch button, the electric connecting sheet 46 driven to rotate together can ensure that the two electric connectors 30 are always connected.

As shown in fig. 19, when the switch button is rotated clockwise, the switch button drives the transmission sleeve 40 to rotate, and the transmission sleeve 40 rotates to drive the third transmission block 42 to rotate; in an initial state, the fifth transmission block 50 and the third transmission block 42 have an overlapping region in the circumferential direction, the third transmission block 42, the fourth transmission block 49 and the fifth transmission block 50 are forward looking, and the fourth transmission block 49 is positioned at the right side of the third transmission block 42, so that the straight surface of the third transmission block 42 is matched with the fourth transmission block 49 at the moment, the fourth transmission block 49 is shifted to rotate by the rotation of the third transmission block 42, the first synchronizing wheel 35 is driven to rotate by the rotation of the third transmission block 42, and the first synchronizing wheel 35 drives the first synchronizing wheel 35 in the adjacent cooking bench unit 1 to rotate by the rotation of the first synchronizing wheel 35; when the first synchronizing wheel 35 in the adjacent cooking bench unit 1 rotates, the fifth transmission block 50 mounted thereon drives the corresponding third transmission block 42 to rotate, i.e., drives the corresponding transmission sleeve 40 to rotate, the rotation of the transmission sleeve 40 drives the switch button to rotate on the one hand, and the switch button rotates to drive the front end control rotating shaft 27 of the first switch valve 6 to rotate through the driving inner rod 36, as shown in fig. 18, since the vent hole of the valve core 54 in the first switch valve 6 is staggered with the air inlet and the air outlet of the first switch valve 6 at the beginning, the first switch valve 6 is in a closed state in the process; on the other hand, the transmission sleeve 40 can drive the guide post 41 mounted thereon to rotate in the rotating process, so that the transmission sleeve 40 rotates clockwise, under the action of the adjusting chute 51, the guide post 41 can drive the transmission sleeve 40 to move inwards, on one hand, the transmission sleeve 40 can drive the electric connecting piece 46 to move through the transmission disc 43, the telescopic inner ring 44 and the telescopic outer sleeve 45, and on the other hand, the transmission sleeve 40 can drive the third transmission block 42 to move, as shown in fig. 20, after the electric connecting piece 46 is contacted with the two electric connectors 30, the third transmission block 42 is not separated from the corresponding fifth transmission block 50, at this time, the third transmission block 42 continues to be driven to rotate, the transmission sleeve 40 continues to move, so that the electric connecting piece 46 is contacted with the two electric connectors 30, the telescopic outer sleeve 45 is limited to move, and the fourth spring 47 between the telescopic inner ring 44 and the telescopic outer sleeve 45 is compressed; that is, the contact between the electrical connection sheet 46 and the electrical connector 30 does not affect the continuous rotation of the corresponding third transmission block 42; during the process that the third transmission block 42 continues to rotate, the first switch valve 6 is opened from the closed state for ventilation, then the third transmission block 42 continues to be driven to rotate, the third transmission block 42 does not stop rotating until the third transmission block 42 is disconnected from the fifth transmission block 50, in the process, the switch button is driven to rotate by 90 degrees, and all the cooking bench units 1 are ignited and opened to the maximum; the reason why the third transmission block 42 and the fifth transmission block 50 are designed to be separated is that the adjustment can be carried out automatically according to the requirement of each cooking bench 5 on the fire intensity during subsequent use, and the adjustment is carried out or is carried out after the adjustment is carried out; that is, such a design does not affect other hob units 1 through the transmission of the first synchronous belt 3 in the process of rotating the switch button counterclockwise when the subsequent single adjustment is desired to be increased due to the small opening width of the hobs 5 when all are simultaneously opened.

In the process that the fifth transmission block 50 of the adjacent cooking bench 5 shifts the third transmission block 42, the control rotation shaft 27 at the rear end of the first switch valve 6 rotates clockwise to drive the installation rotation shaft 20 to rotate through the second synchronous pulley 18 and the second synchronous belt 19, the installation rotation shaft 20 rotates to drive the first transmission wheel 21 to rotate, the first transmission wheel 21 shifts the first transmission block 24 through the cooperation of the second transmission block 26 and the sixth transmission block 58 to drive the second transmission wheel 23 to rotate, the second transmission wheel 23 rotates to drive the control rotation shaft 27 of the second switch valve 10 to rotate, the first volute spring 29 stretches, the second switch valve 10 controls the rotation shaft 27 to rotate clockwise to open the second switch valve 10, namely, the connecting pipe 37 connecting the first switch valve 6 and the gas outlet end 17 is connected, at this time, the gas entering the first switch valve 6 from the gas inlet end 12 can be discharged from the gas outlet end 17 through the connecting pipe 37, and the gas stove is ignited. When the sixth transmission block 58 and the second transmission block 26 are disengaged in the rotation process, the second transmission block 26 loses the toggle force on the sixth transmission block 58, the control rotating shaft 27 of the second switch valve 10 rotates in the reverse direction under the action of the first scroll spring 29, and the rotation speed is relatively slow due to the resistance applied to the control rotating shaft by the damper 28 in the rotation process, that is, the second switch valve 10 is relatively slow in the closing process under the action of the first scroll spring 29; in the closing process of the first one-way valve, the second transmission block 26 reversely rotates and passes through the sixth transmission block 58, in the process, after the second transmission block 26 contacts with the sixth transmission block 58, under the action of the upper inclined plane of the sixth transmission block 58, the sixth transmission block 58 moves inwards, and the first spring 25 is compressed; when the second transmission block 26 passes over the sixth transmission block 58, under the action of the first spring 25, the end of the sixth transmission block 58 with the inclined surface moves out; at this time, the sixth stopper and the second stopper are restored to the initial state. The damper 28 is provided to ensure that the second switching valve 10 can be slowly closed to provide sufficient time for the opening of the third switching valve 11.

When the adjacent cooking bench 5 is opened, each switch button can be adjusted to be large or small and can be independently closed. The closing process of the cooktop 5 is described below.

In an initial state, one of the cooktops 5 is closed, the three cooktops 5 are opened, and the opening degrees are different, the closed cooktop 5 and the third transmission block 42 in the cooktop 5 having a smaller opening degree are restored to the initial positions, and the fourth transmission block 49 is located at the right side of the third transmission block 42.

When the cooktop 5, of which the opening degree is small, is closed among the unclosed cooktops 5, the third transmission block 42 rotates counterclockwise to return to the initial state.

When the cooking bench 5 with the maximum opening degree in the unclosed cooking benches 5 is closed, the first synchronizing wheel 35 enables the fourth transmission block 49 to be tightly attached to the third transmission block 42 to gradually reset counterclockwise under the action of the corresponding second scroll spring 33, the fifth transmission blocks 50 of other cooking benches 5 gradually approach to the third transmission block 42 in the resetting process, when the cooking bench 5 is completely closed, the fifth transmission blocks 50 of all the cooking benches 5 pass through the inclined planes of the corresponding third transmission blocks 42 of the respective cooking benches 5 and reach the left side of the third transmission block 42, the third transmission blocks 42 slide out again under the action of the fifth springs 48 to reset, and the resetting is completed.
