The embodiment stated.
Fig. 1-2 show a specific embodiment of invention electrokinetic adsorption bracket (hereinafter referred to as bracket), including shell 10, peace
Control module 30 loaded on absorbent module 20 and the control operation of absorbent module 20 in shell 10.
The whole shell 10 is in three-legged structure, can be stably placed in any object.The shell 10 includes one
Inclined support plate 12, for placing article to be fixed.The article includes but is not limited to the electronic products such as mobile phone, below with
It adsorbs and bracket of the present invention is described in detail for fixing mobile phone.The absorbent module 20 includes that sucker 22 and sucker 22 connect
The vacuum pump 24 connect and solenoid valve 26 and the check valve 28 being connected between sucker 22 and vacuum pump 24.The sucker 22 is set
It is placed in the outer surface of shell 10, is specifically set in the support plate 12 of shell 10, for adsorbing fixed mobile phone.The sucker 22 with
It is connected by pipeline 40 between solenoid valve 26, sucker 22 and check valve 28, check valve 28 and vacuum pump 24, as shown in Figure 3.?
In the present embodiment, pipeline 40 is preferably hollow tube.The control module 30 is electrically connected with solenoid valve 26, vacuum pump 24, control
The start and stop of solenoid valve 26 and vacuum pump 24.
As shown in figure 3, the sucker 22 is formed with interface A；Check valve 28 is formed with bleeding point E and exhaust outlet F；Vacuum pump
24 are formed with bleeding point G and exhaust outlet H.The bleeding point E of the check valve 28 is connected to by pipeline 40 with the interface A of sucker 22,
Exhaust outlet F is connected to by pipeline 40 with the bleeding point G of vacuum pump 24；The exhaust outlet H of the vacuum pump 24 is connected with outside air
It is logical.When the vacuum pump 24 is powered, bleeding point E, exhaust outlet F of the air sequentially through check valve 28 in sucker 22, pipeline 40,
And it is outwardly discharged after bleeding point G, the exhaust outlet H of vacuum pump 24.The check valve 28 flows air-flow by sucker 22
To vacuum pump 24, but sucker 22 reversely cannot be flowed to by vacuum pump 24.Solenoid valve is 2/2-way solenoid valve, the solenoid valve 26
It is formed with gas outlet I and air inlet J, the gas outlet I be connected to by pipeline 40 with the interface A of sucker 22, air inlet J and outside
