Referring to fig. 1,2 and 3, fig. 1 is a schematic perspective view of a pressure adjusting device 100 according to an embodiment of the application. Fig. 2 is an exploded view of one embodiment of the pressure regulating device 100 of the present application. Fig. 3 is a schematic structural view of an embodiment of the pressure regulating device 100 of the present application. As shown in fig. 1,2 and 3, the pressure regulating device 100 includes a motor 110, a bracket 140, a pressure regulating assembly 120, a detecting assembly 130 and a control circuit.
The motor 110, the voltage regulating assembly 120, and the detecting assembly 130 may be disposed on the bracket 140.
The pressure regulating assembly 120 is used for blocking a predetermined vent hole when the motor 110 rotates in a first direction, and opening the vent hole when the motor 110 rotates in a second direction opposite to the first direction, so as to maintain and release pressure of the cooking appliance.
In this embodiment, the pressure regulating assembly 120 may include a swing arm 121 rotatably supported on a bracket 140. One end of the swing arm 121 may be connected to an output shaft of the motor 110, so that the motor 110 may drive the swing arm 121 to rotate around a preset rotation axis. Specifically, one end of the swing arm 121 may be provided with a second gear 123, an output shaft of the motor 110 may be provided with a first gear 122, and the first gear 122 and the second gear 123 are meshed with each other, so that the swing arm 121 is driven to rotate around a preset rotation axis in the rotation process of the motor 110 along the first direction and the second direction. It will be appreciated that one end of the swing arm 121 may also be connected to the output shaft of the motor 110 in other ways.
The swing arm 121 may also be connected to a pressure regulating lever 124. In this embodiment, the pressure adjusting lever 124 may be connected to the other end of the swing arm 121, and the preset rotation shaft is disposed in the middle of the swing arm 121, that is, the middle of the swing arm 121 is fixed on the bracket 140. Alternatively, the middle of the swing arm 121 may be fixed to the bracket 140 by the pressing cover 125. In other embodiments, a preset rotation shaft may be disposed at the other end of the swing arm 121, and the pressure adjusting lever 124 is connected with the middle of the swing arm 121.
In one implementation, the pressure regulating lever 124 may be connected to the swing arm 121 in an articulated manner.
In another implementation manner, a connecting portion 126 may be disposed at a connection portion between the swing arm 121 and the pressure adjusting lever 124, a sliding groove is disposed on the connecting portion 126, and one end of the pressure adjusting lever 124, which is close to the swing arm 121, is located in the sliding groove and can slide in the sliding groove, so that the pressure adjusting lever 124 is connected with the swing arm 121 through the connecting portion 126, and the rotational movement of the swing arm 121 can be converted into the linear movement of the pressure adjusting lever 124 in the axial direction through the arrangement of the sliding groove in the connecting portion 126.
Further, to limit the moving direction of the pressure adjusting lever 124, a positioning hole 141 may be disposed on the bracket 140, and the pressure adjusting lever 124 is inserted into the positioning hole 141 to position the axial direction of the pressure adjusting lever 124 by the positioning hole 141, so that the motor 110 can drive the pressure adjusting lever 124 to move along the axial direction of the pressure adjusting lever 124 when driving the swing arm 121 to rotate around a preset rotation axis. Thus, the pressure regulating lever 124 may block or open the exhaust hole when the pressure regulating lever 124 moves in the axial direction, so that the cooking appliance may be pressurized and depressurized through the pressure regulating assembly 120. It will be appreciated that the vent may be provided on a side of the pressure regulating lever 124 remote from the swing arm 121.
Wherein the motor 110 is provided with a middle position, wherein the control circuit controls the motor 110 to rotate to the middle position when the cooking appliance is in a non-operating state.
Specifically, after the motor 110 rotates from the middle position to a certain extent along the first direction, the pressure regulating rod 124 can be driven by the structures of the first gear 122, the second gear 123, the swing arm 121, and the like to press down to block the predetermined vent hole, so as to maintain the pressure of the cooking appliance. After the motor 110 rotates to a certain extent along the second direction from the middle, the pressure regulating rod 124 can be driven to lift up through the structures of the first gear 122, the second gear 123, the swing arm 121 and the like to open the preset exhaust hole so as to release the pressure of the cooking utensil.
To facilitate control of the motor 110, the pressure sensing apparatus of the present application includes a sensing assembly 130 and a control circuit. The detecting assembly 130 is used for generating a trigger signal according to the rotation condition of the motor 110. The control circuit is used for responding to the trigger signal to control the motor 110 to stop rotating.
In this embodiment, the detection assembly 130 includes a trigger key 131 and a trigger mechanism, where the trigger mechanism is used to trigger the trigger key 131 after the vent hole is plugged by the voltage regulating assembly and after the vent hole is opened by the voltage regulating assembly, so as to generate a trigger signal.
In this embodiment, the detecting component 130 may further include a detector 132, where the trigger key 131 may be an activation switch disposed on the detector 132, and the trigger key 131 may be triggered to cause the detector 132 to generate the trigger signal. Wherein the triggering of the triggering key 131 may mean that the triggering key 131 is pressed or released to a predetermined position. When the trigger key is triggered, the circuitry within the detector 132 switches from the off state to the on state, and the detector 132 may generate a trigger signal and send the trigger signal to the control circuitry. Preferably, the detector 132 may be a micro switch.
In other embodiments, it may be determined in other ways whether the trigger key 131 is triggered, for example, the trigger key 131 is connected to a pressure sensor, the pressure sensor is connected to a comparator, and the comparator is configured to send a trigger signal to the control circuit when the pressure value transmitted by the pressure sensor is equal to a preset value. That is, when the force applied to the pressure sensor by the trigger key 131 is equal to a preset value, the trigger key 131 is activated.
In this embodiment, the triggering mechanism may be linked with the motor 110, so that the triggering key 131 is triggered after the motor 110 rotates by a predetermined angle along the first direction and the second direction, so that the motor 110 stops rotating after the motor 110 rotates by a predetermined angle along the first direction and the second direction, and no idle rotation of the motor 110 occurs.
The trigger mechanism may include a cam 133. The cam 133 rotates in synchronization with the motor 110, and thus triggers the trigger key 131 after the motor 110 rotates a predetermined angle in the first direction and the second direction. It is understood that "the cam 133 rotates synchronously with the motor 110" as referred to herein means that the cam 133 rotates when the motor 110 rotates, and the cam 133 also stops rotating when the motor 110 stops rotating. And the rotational speeds of the cam 133 and the motor 110 may be the same or different, and the rotational directions of the cam 133 and the motor 110 may be the same or different. As shown in fig. 4, the cam 133 may be directly provided on the output shaft of the motor 110. The cam 133 may alternatively be in driving connection with the output shaft of the motor 110. For example, the cam 133 may be coaxially fixed with the swing arm 121 along the rotation axis. For another example, the cam 133 may be disposed coaxially with the second gear 123.
In one implementation, as shown in fig. 5 and 6, the cam 133 may directly abut against or be separated from the trigger key 131, so that the cam 133 triggers the trigger key 131 after the motor 110 rotates a predetermined angle in the first direction and the second direction, i.e., the cam 133 may cause the trigger key 131 to be pressed or released to a designated position, and the detector 132 generates a trigger signal for the control circuit to control the motor 110 to stop rotating. It can be understood that in this implementation, as shown in fig. 5, in order that the cam 133 can trigger the trigger key 131 after the motor 110 rotates by a predetermined angle along the first direction and the second direction, the cam 133 may have a convex surface 1334, when the motor 110 is in the middle position, the high end 1333 of the cam 133 abuts against the trigger key 131, presses the trigger key 131, and the trigger key 131 does not reach the trigger condition, and when the motor 110 rotates along the first direction or the second direction, the cam 133 can be driven to rotate to a state that the low end 1332 of the convex surface 1334 is opposite to the trigger key 131, and the trigger key 131 is released to a predetermined position, so that the trigger key 131 is triggered to generate a trigger signal for controlling the control circuit to control the motor 110 to stop rotating. The convex surface 1334 may be an arcuate convex surface 1334 or may be a convex surface 1334 of other shapes, provided that the convex surface 1334 has a high end 1333 and two low ends 1332 that trigger the trigger key 131. Of course, in other implementations, as shown in fig. 6, in order that the cam 133 can trigger the trigger key 131 after the motor 110 rotates by a predetermined angle along the first direction and the second direction, the cam 133 may be provided with a concave surface 1331, when the motor 110 is in the middle position, the lower end 1332 of the concave surface 1331 in the cam 133 is opposite to the trigger key 131, the trigger key 131 is released, and the trigger key 131 does not reach the trigger condition, and when the motor 110 rotates along the first direction or the second direction, the cam 133 can be driven to rotate to a state that the upper end 1333 of the concave surface 1331 abuts against the trigger key 131, and the trigger key 131 is pressed to a predetermined position, so that the trigger key 131 is triggered, and a trigger signal for controlling the motor 110 to stop rotating by the control circuit is generated. The concave surface 1331 may be an arcuate concave surface 1331, or may be a concave surface 1331 of other shapes, so long as the concave surface 1331 has a low end 1332 and two high ends 1333 that trigger the trigger key 131. It will be appreciated that the term "high end 1333" as used herein refers to the end of the convex surface 1334 or concave surface 1331 that is farther from the axis of the cam 133, and the term "low end 1332" refers to the end of the convex surface 1334 or concave surface 1331 that is closer to the axis of the cam 133, i.e., the high end 1333 is farther from the axis of the cam 133 than the low end 1332 is from the axis of the cam 133.
In another implementation, as shown in fig. 3 and 7, the triggering mechanism may further include a triggering member 134, where the cam 133 rotates synchronously with the motor 110, and further drives the triggering member 134 to trigger the triggering key 131 after the motor 110 rotates a predetermined angle in the first direction and the second direction.
It is understood that, in order to trigger the trigger key 131 after the motor 110 rotates by a predetermined angle along the first direction and the second direction, as shown in fig. 3, a concave surface 1331 may be provided on the outer circumferential surface of the cam 133, and the concave surface 1331 may be an arc-shaped concave surface 1331 or may be a concave surface 1331 having another shape. When the motor 110 is in the middle position, the lower end 1332 of the arc-shaped concave surface 1331 can drive the trigger piece 134 to loosen the trigger key 131, the trigger key 131 does not reach the trigger condition, and when the motor 110 rotates in the first direction or the second direction, the cam 133 can be driven to rotate until the upper end 1333 of the concave surface 1331 drives the trigger piece 134 to press the trigger key 131 to a preset position, so that the trigger key 131 is triggered, and a trigger signal for enabling the control circuit to control the motor 110 to stop rotating is generated. It will be appreciated that in other implementations, as shown in fig. 7, in order that the cam 133 can trigger the trigger key 131 after the motor 110 rotates a predetermined angle along the first direction and the second direction, a convex surface 1334 may be disposed on the cam 133, where the convex surface 1334 may be an arc-shaped convex surface 1334, or may be a convex surface 1334 with another shape.
In addition, referring to fig. 3, in order to facilitate the cam 133 to drive the trigger 134 to trigger the trigger key 131, an abutment member 135 may be disposed at an end of the trigger 134 near the cam 133. During the rotation of the motor 110 in the first direction and the second direction, the abutting piece 135 abuts against the arc concave surface 1331 and moves along the arc concave surface 1331, so as to drive the trigger piece 134 to trigger the trigger key 131. In order to conveniently trigger the trigger key 131 through the trigger piece 134, one end of the trigger piece 134 is relatively fixed with the trigger key 131, the other end of the trigger piece 134 is provided with an abutting piece 135, in the process that the abutting piece 135 moves along the arc-shaped concave surface 1331, the other end of the trigger piece 134 moves relative to the trigger key 131, the middle part of the trigger piece 134 is abutted with the trigger key 131, the trigger key 131 can be triggered when the trigger key 131 is pressed to a certain degree at the middle part of the trigger piece 134, and therefore a trigger signal for enabling the control circuit to control the motor 110 to stop rotating is generated.
When the motor 110 is in the middle position, the abutting piece 135 is opposite to the bottom of the arc-shaped concave surface 1331 and is arranged at intervals, so that the trigger piece 134 is in a natural state.
To enable the abutment 135 on the trigger 134 to move along the arcuate concave surface 1331, the trigger 134 may be a resilient tab. Therefore, when the arc-shaped groove applies pressure to the other end of the trigger piece 134, the trigger piece 134 can elastically deform, the middle part of the trigger piece 134 presses the trigger key 131, and when the arc-shaped groove does not apply pressure to the other end of the trigger piece 134, the trigger piece 134 slowly recovers, and the trigger key 131 can slowly rebound. Of course, in other embodiments, one end of the trigger 134 is fixed to the detector 132 in a hinged manner, and an elastic member may be further disposed between the trigger 134 and the detector 132, so as to facilitate the elastic member to slowly recover when the arc-shaped groove does not apply pressure to the other end of the trigger 134.
In addition, the abutment 135 may be a roller. Moreover, the radius of curvature of the roller can be smaller than that of the arc-shaped concave surface 1331, so that the roller can form line contact with the arc-shaped concave surface 1331, and the radian and the size of the arc-shaped concave surface 1331 can be conveniently controlled.
The pressure adjusting apparatus 100 may be applied to the cooking appliance 200, and thus the present application also provides the cooking appliance 200. As shown in fig. 8, the cooking appliance 200 includes the pressure adjusting device 100, and thus, the cooking appliance 200 provided by the embodiment of the present application may have all the advantages of the pressure adjusting device 100, which are not listed herein.
The cooking appliance 200 may be an electric rice cooker or an electric pressure cooker.
Referring also to fig. 9, the cooking appliance 200 may include a pot 210 and a cover 220. The cover 220 is connected to the pan 210 and cooperates with the pan 210 to form a cooking cavity 230. The cover 220 may be provided with a vent hole. The exhaust holes may communicate the cooking cavity 230 with the external environment. The pressure regulating device 100 may be disposed on the cover 220, and the pressure regulating assembly 120 of the pressure regulating device 100 may block or open the exhaust hole under the driving of the motor 110.
Optionally, when the pressure regulating assembly 120 includes the swing arm 121 and the pressure regulating rod 124, the end of the pressure regulating rod 124 away from the swing arm 121 seals the exhaust hole when the motor 110 rotates along the first direction, so that the gas in the cooking cavity 230 cannot be released from the exhaust hole to the external environment, and the cooking appliance 200 can be kept under pressure. One end of the pressure regulating lever 124, which is far from the swing arm 121, opens the exhaust hole when the motor 110 rotates in the second direction, and gas in the cooking cavity 230 may be released into the external environment through the exhaust hole, so that the pressure of the cooking appliance 200 may be released.
In other implementations, the pressure regulating device 100 may also be disposed on the pan 210 of the cooking appliance 200.
In summary, when the motor 110 rotates in the first direction, the pressure adjusting assembly 120 seals the predetermined vent hole to keep the pressure of the cooking appliance, and the trigger mechanism in the detecting assembly 130 can trigger the trigger key 131 to generate a trigger signal after the pressure adjusting assembly 120 seals the predetermined vent hole, the control circuit can control the motor 110 to stop rotating in response to the trigger signal, in addition, when the motor 110 rotates in the second direction opposite to the first direction, the pressure adjusting assembly 120 opens the vent hole to release the pressure of the cooking appliance, and after the pressure adjusting assembly 120 opens the vent hole, the trigger mechanism can trigger the trigger key 131 to generate a trigger signal, and the control circuit can control the motor 110 to stop rotating in response to the trigger signal, so that the motor 110 in the pressure adjusting device 100 of the application stops rotating when the motor 110 rotates to a certain extent in the first direction and the second direction, no idle running condition occurs to the motor 110, the motor 110 is not easy to damage, and the service life of the motor 110 can be prolonged.
