The invention provides a pot cover.
In an embodiment of the present invention, as shown in fig. 1, fig. 2, fig. 3, and fig. 4, the pot cover includes a pot cover body 100 and an exhaust valve 200 disposed on the pot cover body 100, the exhaust valve 200 includes an exhaust valve core 210 disposed inside and outside the pot cover body 100 (inner means the side of the pot cover facing the pot body, outer means the outside of the pot cover) and an exhaust valve body 220 disposed at the upper end of the exhaust valve core 210, an exhaust channel 211 extending along the axial direction of the exhaust valve core 210 is disposed in the exhaust valve core 210, two ends of the exhaust channel 211 extend to two ends of the exhaust valve core 210 to form an exhaust hole 212 on the outer side of the pot cover body 100 and an intake hole on the inner side of the pot cover body 100, and the exhaust valve body 220 can move in the up-down direction; the cooker cover further comprises a pressure block 400 and a trigger mechanism, wherein the pressure block 400 is pressed on the exhaust valve body 220, the trigger mechanism is used for separating the pressure block 400 from the exhaust valve body 220 when being triggered so as to prevent the exhaust valve body 220 from being subjected to downward pressure from the pressure block 400, and the weight ratio of the pressure block to the exhaust valve body is 0.26-12.56.
The exhaust channel 211 on the exhaust valve core 210 is used for exhausting the gas in the pressure cooker to the outside of the cooker, and the upper end of the exhaust valve core 210 is provided with an exhaust valve body 220 which can move up and down, thereby realizing the control of the exhaust condition of the exhaust hole 212. The pressure block 400 is pressed on the exhaust valve body 220, and the main function of the pressure block 400 is to increase the downward pressure applied by the exhaust valve body 220 to the exhaust valve core 210 so as to block the exhaust hole 212, so that the gas in the pressure cooker cannot be exhausted.
The cooker cover further comprises a trigger mechanism, and the trigger mechanism is mainly used for adjusting the separation state of the pressure block 400 and the exhaust valve body 220:
when the trigger mechanism is triggered, the pressure block 400 is separated from the exhaust valve body 220, so that the pressure block 400 has no downward pressure on the exhaust valve body 220, thereby reducing the pressure on the exhaust valve core 210, when the pressure in the pressure cooker reaches a certain value, such as 70Kpa, the gas in the pressure cooker can jack up the exhaust valve body 220, so that the exhaust hole 212 is opened, thereby realizing that the pressure cooker can exhaust through the exhaust hole 212, reducing the air pressure in the pressure cooker, reducing the boiling point of the liquid in the pressure cooker, realizing the boiling of the liquid in the pressure cooker, and achieving the aroma effect.
When the trigger mechanism is not triggered, the pressure block 400 is pressed on the exhaust valve body 220, and the pressure on the exhaust valve core 210 is very high, so that when the pressure in the cooker reaches a certain value, such as 70Kpa, the gas in the cooker can not push the exhaust valve body 220, the exhaust hole 212 can not be opened, the pressure cooker can not exhaust, the air pressure in the cooker is increased, the boiling point of the liquid in the cooker is increased, the liquid in the cooker can not be boiled, and the fragrant effect is achieved.
In the practical application process, the triggering mechanism can be determined according to the actual needs, a shifting lever controlled by a button can be used for pushing the pressure block 400 upwards by utilizing a lever after being pressed, and the scheme of sucking the pressure block 400 away from the exhaust valve body 220 can also be realized by the characteristic of magnetic induction, as long as the pressure block 400 can be switched between pressing the exhaust valve body 220 and leaving the exhaust valve body 220.
In order to enable the exhaust mode of the pressure cooker to be adjusted better, the weight ratio of the pressure block 400 to the exhaust valve body 220 is 0.26-12.56. Specifically, the working pressure of the pressure cooker during cooking is generally 70kpa, when the pressure in the pressure cooker reaches 70kpa, the heater of the pressure cooker stops heating, but after the heater stops heating, the residual heat of the heater will cause the pressure in the pressure cooker to slightly exceed 70kpa, for example, reach a pressure value of 71kpa or 72kpa, and then gradually fall back to less than 70kpa, and then the heater starts heating again, so that the pressure in the pressure cooker is maintained at about 70kpa until the cooking is finished, therefore, the weight ratio of the pressure block 400 to the exhaust valve body 220 is best adjusted between 0.26 and 12.56, if the weight ratio of the pressure block 400 to the exhaust valve body 220 is less than 0.26, the downward pressure exerted by the pressure block 400 on the exhaust valve body 220 due to its own gravity is relatively small, when a user needs a fragrant effect, the exhaust valve body 220 and the pressure block 400 are relatively easily pushed up by steam in the pressure cooker, that is, when the pressure in the pressure cooker slightly exceeds 70kpa, the steam in the pressure cooker may overcome the dual pressure of the pressure block 400 and the exhaust valve 220 to push the exhaust valve 220 open for exhaust, so that the fragrant effect is not achieved. If the weight ratio of the pressure block 400 to the exhaust valve body 220 is greater than 12.56, the gravity of the pressure block 400 is large, when a user needs a strong fragrance effect, the difficulty of separating the pressure block 400 from the exhaust valve body 220 when the trigger mechanism enters the trigger state is greatly increased, the implementation is difficult, the situation that the pressure block 400 and the exhaust valve body 220 are still not separated after the trigger mechanism enters the trigger state is easy to occur, and therefore the pressure cooker cannot exhaust gas and cannot achieve the strong fragrance effect.
Optionally, in an embodiment of the present invention, a weight ratio of the pressure block 400 to the exhaust valve body 220 is 0.89, and the weight ratio has the best effect on adjusting the exhaust mode of the pressure cooker.
According to the technical scheme, the pressure block 400 and the trigger mechanism are arranged on the exhaust valve body 220, the pressure block 400 is separated from the exhaust valve body 220 when the trigger mechanism is triggered, the pressure block 400 is pressed on the exhaust valve body 220 when the trigger mechanism is not triggered, and the downward pressure applied to the exhaust valve body 220 by the pressure block 400 is adjusted, so that the downward pressure of the exhaust valve core 210 is adjusted, and the effect of adjusting the exhaust mode of the pressure cooker is achieved.
Further, referring to fig. 1, 2, 3 and 4, the triggering mechanism includes an adsorption block 300 movably disposed, the adsorption block 300 and a pressure block 400 have an attraction force between them decreasing with increasing distance and increasing with decreasing distance, the adsorption block 300 is movable between a first position close to the pressure block 400 and a second position far from the pressure block 400 to adjust the pressure of the pressure block 400 on the exhaust valve body 220. When the adsorption block 300 is close to the pressure block 400, a certain attractive force is generated to the pressure block 400, and when the attractive force of the adsorption block 300 is large enough, the adsorption pressure block 400 is away from the exhaust valve body 220; when the suction force of the suction block 300 to the pressure block 400 is small, the pressure block 400 cannot be sucked away from the exhaust valve body 220, but the pressure of the pressure block 400 to the exhaust valve body 220 is reduced under the suction force; when the suction block 300 is far from the pressure block 400 and there is no suction force to the pressure block 400, the pressure block 400 is still pressed against the exhaust valve body 220.
In practical applications, the exhaust manner may be adjusted according to the distance between the adsorption block 300 and the pressure block 400.
When the aroma effect is needed: when the adsorption block 300 is moved closer to the pressure block 400, the pressure of the pressure block 400 against the exhaust valve body 220 is reduced. When the attraction force of the adsorption block 300 to the pressure block 400 is large enough, the pressure block 400 is sucked away from the exhaust valve body 220 by the adsorption block 300; when the suction force of the adsorption block 300 to the pressure block 400 is small, the pressure of the pressure block 400 pressing on the exhaust valve body 220 is reduced, so that the downward pressure applied to the exhaust valve core 210 is reduced, when the pressure in the pressure cooker reaches a certain value, such as 70Kpa, the gas in the pressure cooker can jack up the exhaust valve body 220, so that the exhaust hole 212 is opened, the pressure cooker can exhaust through the exhaust hole 212, the air pressure in the pressure cooker is reduced, the boiling point of the liquid in the pressure cooker is also reduced, the boiling of the liquid in the pressure cooker is realized, and the aroma effect is achieved.
When the fragrant effect is needed: when the adsorption block 300 is moved away from the pressure block 400, the adsorption block 300 does not attract the pressure block 400, and the pressure block 400 is still pressed on the exhaust valve body 220 to increase the downward pressure applied to the exhaust valve core 210, so that when the pressure in the cooker reaches a certain value, for example, 70Kpa, the gas in the cooker cannot push the exhaust valve body 220, the exhaust hole 212 cannot be opened, the pressure cooker cannot exhaust, the air pressure in the cooker increases, the boiling point of the liquid in the cooker also increases, the liquid in the cooker cannot boil, and the fragrant effect is achieved.
Further, referring to fig. 1 and 3, the pot cover further includes a bubble breaker 500 covering the exhaust valve 200 and an adsorption block mounting base 600 movably connected to a cover body of the bubble breaker 500, and the adsorption block 300 is mounted on the adsorption block mounting base 600. The main function of the bubble breaker 500 is to prevent large bubbles from overflowing from the pan. When the gas in the pot is discharged from the exhaust passage 211, it flows into the bubble breaker 500, and the bubble breaker 500 is provided with an opening 510, so that the gas can be smoothly discharged to the air through the opening 510. The adsorption block 300 is installed in the adsorption block installation base 600, the adsorption block installation base 600 is directly arranged on the foam breaker 500, and the distance between the adsorption block 300 and the pressure block 400 can be adjusted, so that the adsorption block installation base 600 is movably connected with the cover body of the foam breaker 500. In practical application, the adsorption block mounting base 600 and the cover body of the bubble breaker 500 can be hinged or slidably connected, if the adsorption block mounting base 600 is hinged, a user can adjust the distance between the adsorption block 300 and the pressure block 400 by rotating the adsorption block mounting base 600, and the adsorption block mounting base 600 can rotate along the vertical direction and also can rotate along the horizontal direction; if the suction block is slidably connected, a sliding rail or a sliding groove may be disposed on the cover of the bubble breaker 500 or the suction block mounting base 600, so as to adjust the distance between the suction block 300 and the pressure block 400.
Further, in order to improve the effect of the suction block 300 sucking the pressure block 400 away from or covering the exhaust valve body 220, the suction block 300 may be disposed in a positional relationship with the pressure block 400.
Alternatively, referring to fig. 1 and 3, the suction block mounting seat 600 is provided at the top end of the discharge valve 200, and the suction block 300 sucks the pressure block 400 to move upward. In this embodiment, when the aroma effect is needed, the adsorption block mounting base 600 can be adjusted to the top end of the exhaust valve 200, and the adsorption block 300 adsorbs the pressure block 400 to move upwards to leave the exhaust valve body 220, so that only the exhaust valve body 220 is pressed on the exhaust valve core 210, and further, when the pressure in the cooker reaches a certain value, such as 70Kpa, the exhaust valve body 220 can be pushed open to exhaust. When a fragrant effect is required, the adsorption block mounting seat 600 is adjusted to be away from the pressure block 400, the pressure block 400 falls down on the exhaust valve core 220 from the adsorbed position, the downward pressure applied to the exhaust valve core 210 is increased, the exhaust valve body 220 cannot be pushed open, and the effect of no exhaust fragrance is achieved. In practical applications, the exhaust valve body 220 may be guided by a guide rod to move up and down more stably, and in this embodiment, the pressure block 400 is preferably disposed to fit over the guide rod to make the movement of the pressure block 400 more stable.
Optionally, the suction block mounting seat 600 is disposed at a side portion of the exhaust valve 200, and the suction block 300 sucks the pressure block 400 to move left and right. The pressure block 400 mainly functions to increase the downward pressure applied by the exhaust valve body 220 to the exhaust valve core 210, so that no special requirement is made on the shape and structure of the pressure block 400, the pressure block 400 can be set to be in a C shape or an L shape, and at the moment, the distance between the adsorption block mounting seat 600 and the pressure block 400 is adjusted on the side surface, namely, the attractive force between the adsorption block 300 and the pressure block 400 is adjusted, so that the pressure block 400 can move left and right to leave the exhaust valve body 220, and the downward pressure applied by the exhaust valve body 220 to the exhaust valve core 210 is adjusted.
Further, one of the adsorption block 300 and the pressure block 400 is made of a magnetic material, and the other is made of a magnetic conductive material.

It is only necessary to ensure a sufficient attractive force between the suction block 300 and the pressure block 400. Meanwhile, the exhaust valve core 220 is preferably made of a magnetic insulating material, so that the exhaust valve core 220 is prevented from interfering with the adjustment between the adsorption block 300 and the pressure block 400.
