With reference to Fig. 1-Fig. 4 descriptions pressure-detecting device 100 for kitchen appliance according to embodiments of the present invention.
As Figure 1-Figure 4, the pressure-detecting device 100 for kitchen appliance according to embodiments of the present invention includes：Shell
Body 10, flexible seals 20, magnetic part 30, induction pieces 40 and detection unit.Explanation is needed exist for, " magnetic part 30 " is one
Kind permeability magnetic material part, magnetic part 30 itself is without magnetic, such as magnetic part 30 can be ferrite.
Chamber is defined in housing 10, there is the through hole 121 of first through hole 111 and second with chamber on housing 10,
Flexible seals 20 are located in chamber, and the outer peripheral edge of flexible seals 20 is connected with the internal perisporium sealing of housing 10 and divides chamber
First chamber 112 and second chamber 122 arranged spaced apart are divided into, first chamber 112 connects first through hole 111, second chamber
122 the second through holes 121 of connection.
Flexible seals 20 deform upon according to the pressure change of first chamber 112 and second chamber 122, for example, working as
When the pressure of first chamber 112 is larger, flexible seals 20 move towards second chamber 122, if on the contrary, second chamber 122 is pressed
When power is larger, flexible seals 20 move towards first chamber 112.
Magnetic part 30 is located in second chamber 122, and at least a portion of magnetic part 30 is wrapped up simultaneously by flexible seals 20
It is connected with flexible seals 20, when flexible seals 20 produce deformation with first chamber 112 and the pressure change of second chamber 122
When, magnetic part 30 is moved with the deformation of flexible seals 20, and induction pieces 40 are located in second chamber 122, and induction pieces 40 with
Magnetic part 30 coordinates, and magnetic part 30 produces magnetic field, and induction pieces 40 are among magnetic field, when magnetic part 30 is moved, magnetic field
It is moved, the magnetic field intensity and direction around induction pieces 40 change, and thus induction pieces 40 produce corresponding feedback, such as
Electric signal can be fed back, detection unit is connected with induction pieces 40, and receives the feedback information of induction pieces 40, and detection unit is according to sense
The feedback information of part 40 is answered to obtain the pressure of first chamber 112, so as to obtain testing pressure.
Thus, according to the pressure-detecting device 100 for kitchen appliance of the present invention, in real time and can be accurately detected
Testing pressure, the detection to kitchen appliance working condition is realized, ensure the normal work of kitchen appliance, moreover, flexible seals
At least a portion of 20 coated magnetic parts 30, on the one hand, the connection that can be improved between magnetic part 30 and flexible seals 20 is steady
Qualitative and reliability, prevent magnetic part 30 from moving the detection essence of inconsistent influence pressure-detecting device 100 with flexible seals 20
Degree, on the other hand, the attachment structure between magnetic part 30 and flexible seals 20 is eliminated, can be with adherence pressure detection means
100 efficiency of assembling, also reduces production cost.
As shown in figure 1, according to one embodiment of present invention, magnetic part 30 is noted as inserts and the one of flexible seals 20
It is moulded into type.That is, when flexible seals 20 produce, magnetic part 30 is placed on to the injection mold of flexible seals 20
It is interior, thus, the bonding strength of magnetic part 30 and flexible seals 20 can be not only lifted, prevent magnetic part 30 and flexible seals
20 depart from, and simplify the attachment structure between magnetic part 30 and flexible seals 20, be advantageous to be lifted magnetic part 30 with it is soft
The efficiency of assembling of property seal 20, furthermore, it is integrally formed that performance and the structural stability of part are higher, and service life is longer.
As shown in Figures 2 to 4, according to one embodiment of present invention, flexible seals 20 include：Lamellar body portion 21 and fixation
Portion 22, lamellar body portion 21 are generally formed into the circular sheet-like structures coaxially arranged with first chamber 112, the outer peripheral edge in lamellar body portion 21 with
The internal perisporium of chamber is tightly connected, and chamber is divided into first chamber 112 and second chamber 122, and fixed part 22 is connected to piece
Body portion 21 is towards on a side surface of second chamber 122, and fixed part 22 wraps up magnetic along the axially extending of housing 10, fixed part 22
At least a portion of property part 30.
Lamellar body portion 21 and fixed part 22 form the flexible seals 20 formed, on the one hand, and lamellar body portion 21 can separate chamber,
The relative seal of first chamber 112 and second chamber 122 is lifted, on the other hand, by setting fixed part in lamellar body portion 21
22 can provide conveniently for the connection of lamellar body portion 21 and magnetic part 30, and can be adjusted according to the parcel area size of magnetic part 30
The size of fixed part 22 is saved, is advantageous to lift the connective stability between magnetic part 30 and flexible seals 20.
As shown in Figures 2 to 4, in some instances, fixed part 22 is connected to the middle part in lamellar body portion 21 and formed along housing
10 axially extending column, specifically, fixed part 22 can be cylinder or cross section is square or other
The column structure of polygon, magnetic part 30 are wrapped in column fixed part 22.
Fixed part 22 is arranged to column, can be not only that the coated magnetic part 30 of fixed part 22 provides conveniently, and column
The resistance that structure is axially moveable is smaller, and the space of the occupancy in moving process is smaller, can be that testing pressure changes flexibility
It is convenient that the movement of seal 20 provides, and prevents from influenceing the movement of flexible seals 20, Jin Erti because the moving resistance of fixed part 22 is excessive
The accuracy of detection of pressure-detecting device 100 is risen.
As shown in Figures 2 and 3, whole magnetic is coated according to some optional embodiments of the present invention, flexible seals 20
Part 30, that is to say, that whole magnetic part 30 is wrapped in fixed part 22, due to passing through electricity between magnetic part 30 and induction pieces 40
Magnetic action mutual induction, therefore, flexible seals 20, which wrap up whole magnetic part 30, can't influence pressure-detecting device 100 just
Often work, and flexible seals 20 wrap up whole magnetic part 30 and can prevent moisture attacks, damage magnetic part 30, are advantageous to prolong
The service life of long magnetic part 30, furthermore, magnetic part 30 and flexible seals 20 are formed as a part, by increasing capacitance it is possible to increase during compression
Stability.
Explanation is needed exist for, the size of the fixed part 22 of flexible seals 20, the size of magnetic part 30 can roots
Selected according to needs, for example, in magnetic part 30 less using size, the less flexibility of the diameter of fixed part 22 can be selected
Seal 20, so as to be advantageously implemented the miniaturization of pressure-detecting device 100.
As shown in figure 3, in some instances, magnetic part 30 forms solid cylindrical and is embedded in fixed part 22, it is specific and
Speech, magnetic part 30 can be the column structure being located in fixed part 22, and the axial direction of column magnetic part 30 can be with fixed part 22
It is axially in parallel.
On the one hand, column magnetic part 30 is along the axially extending of fixed part 22, it is possible to reduce the space-consuming of magnetic part 30, enters
And the volume of fixed part 22 can be reduced, on the other hand, column magnetic part 30 can coordinate with toroidal inductive part 40, column magnetic
Part 30 is located in toroidal inductive part 40 and along the axial movement of toroidal inductive part 40, is advantageous to lift magnetic part 30 and induction pieces 40
Between induction, and then can be with the accuracy of detection of adherence pressure detection means 100.
