The pressure value of detection；When pressure value is more than or equal to threshold value, open signal is exported；When pressure value is less than threshold value, output
Shutdown signal；
Switch, is set at the fluid hole, the controller electrical connection, for receiving the control information of controller, control
The on and off of fluid apertures is made, the control information includes open signal and shutdown signal.
Specifically, the on-off control system further includes:
Memory module is electrically connected with the controller, for storing threshold value set by user.
Specifically, the switch is electric-controlled switch.
The utility model obtains following technique effect using above-mentioned technical proposal：
1. the utility model, by setting liquid storage cylinder inside whiteboard eraser, when needing to wipe blank, liquid can pass through
Liquid storage cylinder seepage flow, can be easy to use thoroughly by blank wiped clean to cleaning part.
2. the utility model is by setting on-off control system, when since when wiping person's handwriting is difficult to wipe, user only needs
The pressure value detected is passed to controller by increase wiping pressure, pressure sensor, the unlatching of controller automatic control switch,
So that fluid hole is opened, the liquid in containing liquid chamber is oozed out by fluid hole, increases the cleaning capacity of whiteboard eraser, it may be difficult to removing
Person's handwriting wiped clean；When user easily reduces wiping pressure because wiping, controller is less than threshold value according to the pressure value detected,
The closure of automatic control switch so that fluid hole is closed.
3. the utility model can automatically control unlatching and the closure of fluid hole, a side by on-off control system as needed
Face greatly improves the property easy to use of whiteboard eraser, on the other hand effectively avoids the waste of liquid in containing liquid chamber.
Description of the drawings

Fig. 2 is the structure diagram of the on-off control system of the utility model embodiment；
Reference numeral lists as follows：Cleaning part 1, grip part 2, containing liquid chamber 21, fluid hole 22, inlet opening 23, spongy layer 11,
Face brush layer 12, on-off control system 3, pressure sensor 31, controller 32, switch 33, memory module 34.
Specific embodiment
In order to solve problem of the prior art, the utility model provides a kind of Multifunctional whiteboard eraser, can be according on blank
Person's handwriting wiping to be wiped is difficult to degree, feeds special liquid medicine to whiteboard eraser automatically, without manually spraying, on the one hand improves
On the other hand the cleaning capacity of whiteboard eraser greatly improves the property easy to use of whiteboard eraser.
Below in conjunction with the accompanying drawings 1 and attached drawing 2, the technical solution of the utility model is further described, makes this field
Technical staff can be better understood from the utility model and can be practiced.
A kind of Multifunctional whiteboard eraser, including cleaning part 1 and grip part 2, the cleaning part 1 and grip part 2 are detachably connected,
Containing liquid chamber 21 in the grip part 2 is set, deviates from the inlet opening 23 of 2 side of grip part positioned at the containing liquid chamber 21 and positioned at residing
Containing liquid chamber 21 is towards the fluid hole 22 of 2 side of grip part；The cleaning part 1 includes being set to the grip part 2 towards wiping
It wipes the spongy layer 11 of 1 side of portion and is coated on the face brush layer 12 that spongy layer 11 deviates from 2 side of grip part；It is set on the containing liquid chamber
On-off control system 3, the on-off control system 3 according to cleaning part 1 receive ambient pressure control fluid hole 22 on and off.
The utility model inside whiteboard eraser by setting liquid storage cylinder, and when needing to wipe blank, liquid can pass through liquid storage cylinder seepage flow
It, can be easy to use thoroughly by blank wiped clean to cleaning part 1.
Specifically, the on-off control system 3 includes:
Pressure sensor 31, positioned at the spongy layer 11, for detecting the pressure value by the external world of spongy layer 11；
Controller 32 is set to inside the grip part 2, is electrically connected with the pressure sensor 31, is received the pressure
The pressure value that sensor 31 detects；When pressure value is more than or equal to threshold value, open signal is exported；When pressure value is less than threshold value
When, export shutdown signal；
Switch 33, is set at the fluid hole 22, the controller 32 is electrically connected, for receiving the control of controller 32
Information, controls the on and off of fluid hole 22, and the control information includes open signal and shutdown signal.
In the present embodiment, when since when wiping person's handwriting is difficult to wipe, user need to only increase wiping pressure, pressure sensing
For device 31 by the pressure signal transmission detected to controller, controller 32 judges whether pressure signal is more than threshold value, when pressure is believed
When number being more than threshold value, open signal is sent out, control switches on so that fluid hole is opened, and the liquid in containing liquid chamber 21 can lead to
It crosses fluid hole 22 to ooze out, increases the cleaning capacity of whiteboard eraser, it may be difficult to the person's handwriting wiped clean of removing；When user is easy because wiping
When reducing wiping pressure, controller 32 judges whether pressure signal is more than threshold value, when pressure signal is less than threshold value, sends out closing
Signal controls the closing of switch so that fluid hole is closed.The on-off control system realizes fluid hole 22 by the above process
It opens and closes automatically, on the one hand greatly improves the property easy to use of whiteboard eraser, on the other hand effectively avoid liquid in containing liquid chamber
The waste of body.
Specifically, the on-off control system 3 further includes:
Memory module 34 is electrically connected with the controller 32, for storing threshold value set by user.
The setting of the threshold value can need to wipe required pressure value according to user to set,
Specifically, the switch 33 is electric-controlled switch.
