Exhaust valve component 100 according to an embodiment of the present invention is specifically described with reference to the accompanying drawing.
As shown in Figures 1 to 8, exhaust valve component 100 according to an embodiment of the present invention, comprising: valve body 10,20 and of exhaust cap
Memory alloy part 30.Wherein, valve body 10 is equipped with air inlet 12, and exhaust cap 20 is movably located on valve body 10, memorial alloy
The both ends of part 30 are connect with valve body 10 and exhaust cap 20 respectively, the memory alloy part when gas flow temperature is greater than or equal to preset temperature
30 deform and are suitable for driving exhaust cap 20 mobile so that air inlet passes through the exhaust outlet 23 set in exhaust cap or passes through exhaust cap
Gap and extraneous conducting between valve body.Specifically, when gas flow temperature is more than or equal to 60 DEG C and is less than or equal to 95 DEG C, note
Recall the deformation of alloy components 30 and is suitable for driving exhaust cap 20 mobile so that air inlet passes through the exhaust outlet 23 set in exhaust cap or logical
Cross the gap between exhaust cap and valve body and extraneous conducting.
Exhaust valve component 100 can be applied on cooking apparatus, and cooking apparatus usually has cooking space, for example, can be with
Exhaust valve component 100 is applied on the cooking apparatus product such as electric cooker, electric pressure cooking saucepan, electric steamer.Exhaust valve component 100 can be with
It is mounted on cooking apparatus product using dismountable mode.The steam or air-flow generated inside cooking apparatus passes through air inlet
12 enter in exhaust valve component 100, when steam or air-flow make the temperature of memory alloy part 30 be more than or equal to memory conjunction
When the deformation temperature of golden part 30, memory alloy part 30 can deform, and drive exhaust cap 20 mobile so that exhaust valve component 100
Interior steam or air-flow is connected by the exhaust outlet in exhaust cap or by the gap between exhaust cap and valve body with extraneous, from
And a part of steam can be discharged, avoid the food in cooking space from overflowing.When temperature decreases below memory alloy part 30
When deformation temperature, memory alloy part 30 can restore state, that is, memory alloy part 30 returns back to undeformed state, row
Gas lid 20 is not turned on air inlet on the inner and outer boundary of exhaust valve component, and the cooking space in cooking apparatus is still sealing state, keeps away
Non-evaporating vapour, which outwardly overflows, causes the temperature in cooking space to reduce, so as to improve the utilization rate and heat insulation effect of heat.
Specifically, defining the first airflow channel 11 in valve body 10, the first airflow channel 11 is connected with air inlet 12.Exhaust
The second airflow channel 21 is limited between lid 20 and valve body 10, the second airflow channel 21 and the first airflow channel 11 are connected.Memory
Alloy components 30 are located in the second airflow channel 21, and when temperature is greater than or equal to preset temperature, memory alloy part 30 deforms and is suitable for
Drive exhaust cap 20 mobile so that air inlet is connected by the gap between exhaust cap or exhaust cap and valve body with extraneous.
Steam or air-flow in cooking space can enter the first air-flow of valve body 10 by the air inlet 12 of valve body 10
Channel 11, and 21 mutual conduction of the first airflow channel 11 and the second airflow channel, steam can be flowed from the first airflow channel 11
To the second airflow channel 21.When the heated liquid in cooking apparatus, the steam in cooking space is entered to via air inlet 12
Second airflow channel 21, and the temperature of steam be more than or equal to memory alloy part 30 deformation temperature when, memory alloy part
30 can deform, and exhaust cap 20 can be driven mobile for memory alloy part 30 so that the second airflow channel 21 is connected with extraneous, from
And a part of steam can be discharged, avoid the food in cooking space from overflowing.When cooking apparatus begins to warm up or heats just
When end or low-power heat, the steam generated inside cooking apparatus is reduced, and the temperature of steam may be lower, the temperature of steam
When degree may be lower than the deformation temperature of memory alloy part 30, memory alloy part 30 can restore state, that is, memory is closed
Golden part 30 returns back to undeformed state, and exhaust cap 20 can close the second airflow channel 21, the second airflow channel 21 will not with it is outer
Boundary is connected, and the cooking space in cooking apparatus is still sealing state, and steam is avoided outwardly to overflow the temperature caused in cooking space
Degree reduces, so as to improve heat insulation effect.
Exhaust valve component 100 according to an embodiment of the present invention as a result, is closed by the way that memory is arranged in exhaust valve component 100
Golden part 30, memory alloy part 30 can drive the second airflow channel 21 and the external world conductive and nonconductive according to vapor (steam) temperature
State between switch, specifically, when in cooking apparatus heated liquid boiling when, vapor (steam) temperature may be greater than or equal to memory
The deformation temperature of alloy components 30, memory alloy part 30 can be deformed to drive exhaust cap 20 mobile, to make the second airflow channel
21 are connected with extraneous, discharge a part of steam in cooking space, the food in cooking space is avoided to overflow；When cooking apparatus exists
At the end of just beginning to warm up or heat, the steam generated inside cooking apparatus is reduced, and vapor (steam) temperature may be less than memory and close
The deformation temperature of golden part 30, memory alloy part 30 restore, and the second airflow channel 21 is not connected with the external world, in cooking apparatus
Cooking space is still sealing state, and avoiding steam from outwardly overflowing causes the temperature in cooking space to reduce, and culinary art can be improved
The heating efficiency and heat insulation effect of utensil, to keep cooking apparatus more energy-efficient.
Optionally, the range of the preset temperature of memory alloy part 30 is 50 DEG C -100 DEG C, that is, memory alloy part 30
Deformation temperature is 50 DEG C -100 DEG C.It preferably 60 DEG C -95 DEG C, both can guarantee in insulating process, the heat preservation temperature in cooking apparatus
Degree is lower than preset temperature, and memory alloy part 30 will not deform, and the cooking space in cooking apparatus remains sealing state, keeps away
Non-evaporating vapour, which outwardly overflows, causes the temperature in cooking space to reduce, and improves heat insulation effect；It can guarantee during heating, cook again
When the vapor (steam) temperature prepared food in utensil improves, memory alloy part 30 can be exhausted in deformation in time, effectively avoid overflowing.
In the specific embodiment of the present invention, valve body 10 includes: valve seat 101 and valve deck 102.Wherein, air inlet
12 are formed in the bottom of valve seat 101, and valve deck 102 is connected to the top of valve seat 101, and valve seat 101 and valve deck 102 limit the jointly
