The part not being held down does not deform upon.Therefore, the contact area of the first conductive layer 01 and the second conductive layer 02 and hairbrush roll-in
Enter area essentially identical.It is understood that contact area is different, the resistance of brush roll press-in quantity sensor is also different, therefore
After brush roll press-in quantity sensor is accessed into circuit, the electric signal produced in circuit also with brush roll press-in area it is different without
Together, can determine that contact area (the namely brush roll of the first conductive layer 01 and the second conductive layer 02 by detecting the electric signal
Press-in area), according to contact area, then calculated (brush roll intrusion is for example calculated according to Pythagorean theorem) by geometry, just may be used
Obtain brush roll intrusion.

Liquid 06 is closed.
In the present embodiment, supporter 03 between the first conductive layer 01 and the second conductive layer 02 is interval setting, due to the
Two conductive layers 02 have flexibility, if the spacing distance of supporter 03 is excessive or the second conductive layer 02 is flexible excessive, second is conductive
May partly occur in the case of without external pressure is subject to without the supporting zone of supporter 03 (i.e. interval region) in layer 02
Deformation.It is therefore preferable that filling iknsulating liquid 06 between the first conductive layer 01 and the second conductive layer 02, the second conductive layer 02 is prevented
Deformed upon when not being under pressure and contacted with the first conductive layer 01, cause contact area to become big, in turn result in hairbrush roll-in
Enter measurement inaccurate.
Iknsulating liquid 06 is without fixed structure, it is necessary to set envelope between the first conductive layer 01 and the edge part of the second conductive layer 02
Material 07 is closed so that space-closed between two conductive layers, will supporter 03 be sealed in the first conductive layer 01 with iknsulating liquid 06

Exempt from when the second conductive layer 02 is under pressure, the movement of supporter 03 is gathered in certain, causes the second conductive layer 02 to be led with first
Electric layer 01 cannot be contacted or contact area is excessive (i.e. contact area is pressed into area much larger than brush roll), and then cause brush roll
Press-in measurement is inaccurate.
Embodiment 2：
As shown in Figures 1 to 5, the present embodiment provides a kind of brush roll press-in measuring device, and it includes：The institute of embodiment 1

Wherein, electric signal can be voltage, electric current, resistance etc..Corresponding detection unit can for ammeter, voltmeter,
Ohmmeter etc..
Preferably, detection unit is ammeter, more preferably high precision electro flow table.When contact area changes, measurement electricity

Electric signal in two branch roads of detection, the electric signal is electric current.
Wherein, the first pole represents the positive and negative polarities of power supply with the second pole point, does not limit specifically.
Wherein, first direction is that (for example brush roll is pressed into the length side of quantity sensor in a direction parallel with conductive layer
To).Thus, after brush roll 08 and brush roll intrusion sensor contacts and press-in, press-in area (length in other words) only meeting
Change is produced in the first direction.
Specifically, the pole of power supply one is connected on the middle part that the second conductive layer 02 is gone up in the first direction, it is conductive that another pole is connected on first
01 both ends in a first direction of layer.During measurement, brush roll 08 is pressed in the middle part of the second conductive layer 02, and (i.e. brush roll intrusion is passed
Sensor middle part), therefore after press-in, electric current flows out from the pole of power supply one, in the first conductive layer 01 and the contact portion of the second conductive layer 02
In, propagated to both sides by less second conductive layer 02 of resistance, and after contact portion is flowed through, electric current enters back into the of both sides
One conductive layer 01 is propagated, and respectively enters two branch roads, eventually enters into another pole of power supply, therefore its equivalent circuit is as shown in Figure 4.
When intrusion changes, the area that the middle part of the second conductive layer 02 contacts with the first conductive layer 01 also changes, i.e. electric current
The distance change propagated respectively in the second conductive layer 02 and the first conductive layer 01, due to the resistance of two conductive layers, therefore phase
When two resistance Rx1, Rx2 change in Fig. 4, therefore electric current in two branch roads can also change, by measurement stream oversampling circuit
In electric current (for example seeking electric current sum in two branch roads), you can measure the intrusion of brush roll 08.
Preferably, brush roll press-in measuring device also includes：Converting unit, for by detected by detection unit
Electric signal is converted to brush roll intrusion.
It is understood that there is dependency relation with brush roll press-in area in the electric signal detected by detection unit, because
This, can be converted directly into brush roll intrusion by setting converting unit by electric signal, facilitate staff to read.
Specifically, this converting unit can include：Signal deteching circuit and signal processing module.Wherein, signal detection
