In this embodiment, the main control circuit 5 is powered by the battery 7, and the main control circuit 5 can be started by the switch key.

The working principle of the device is as follows:

setting the stroke of the automatic identification liquid outlet pump: after the bottle fixing buckle 4 is adjusted, the switch button is pressed to start the main control circuit 5, at the moment, the hand approaches the infrared induction device 6, the infrared induction device 6 transmits induction signals to the main control circuit 5, the main control circuit 5 transmits the signals to the driving motor 11 and the revolution counter 14, at the moment, the driving motor 11 receives the signal of the main control circuit 5, the driving motor 11 is electrified to rotate, the toggle pressure rod 13 is driven to press the liquid outlet pump, when the liquid pump is completely pressed, the driving motor 11 generates a large current exceeding the normal rotation due to the rotation blockage because the pushing pressure rod 13 is blocked and can not be pressed continuously, and the large current is detected by the main control circuit 5, meanwhile, the revolution counter 14 records the revolution of the driving motor 11 and feeds the revolution back to the main board circuit, and the main control circuit 5 takes the revolution as the liquid outlet stroke of the liquid outlet pump in use and records and stores the revolution, so that the function of automatically identifying the stroke of the liquid outlet pump is realized.

The utility model discloses in, through the record and set for the required driving motor 11's of play liquid revolution and realize the automatic regulation of going out liquid and play liquid measure, need realize through the interact of main control circuit 5 and actuating mechanism 1, through foretell setting, main control circuit 5 has set for when going out liquid bottle 8 is the biggest liquid, the revolution that driving motor 11 needs automatically.

When the device is normally used, a hand extends into a sensing area of the infrared sensing device 6, the infrared sensing device 6 transmits a sensing signal to the main control circuit 5, the main control circuit 5 is electrically connected with the revolution counter 14 and the driving motor 11, so that the main control circuit 5 can transmit an electric signal to the revolution counter 14 and the driving motor 11, the driving motor 11 is electrified to rotate after receiving the signal, the driving motor 11 rotates clockwise, the revolution is set in advance by the main control circuit 5, meanwhile, the revolution counter 14 can record the revolution of the driving motor 11 and feed back the revolution to the main control circuit 5 in real time, whether the actual revolution of the driving motor 11 reaches the revolution set by the main control circuit 5 or not is monitored in real time, and when the driving motor 11 finishes the revolution set by the main control circuit 5, a liquid discharging pump arranged in the liquid discharging bottle 8 finishes liquid discharging;

when the driving motor 11 rotates, the driving motor 11 can drive the first gear 122 to rotate together, then the second output shaft 1231 of the second gear 123 drives the grating 141 connected with the driving motor to rotate, so that the work of the revolution counter 14 is realized, meanwhile, the third gear 124 drives the toggle compression rod 13 to slide up and down, and as the toggle compression rod 13 is used for controlling the liquid outlet state of the liquid outlet pump in the liquid outlet bottle 8, the liquid outlet pump can be extruded through the up-and-down reciprocating motion of the toggle compression rod 13, so that automatic liquid outlet is realized; meanwhile, the grating 141 is provided with a plurality of light-transmitting gaps 143, the grating 141 rotates, infrared light coupling light signals can be blocked when the grating rotates to a place without the light-transmitting gaps 143, the revolution number of the motor is calculated and transmitted to the main control circuit 5, the stroke of the reciprocating motion of the pressing rod 13 is controlled and stirred, the infrared light coupling is good in adaptability to the use environment, the influence of light rays of use occasions can be avoided, special shading treatment is not needed, infrared induction can not be influenced, counting of the driving motor 11 can be achieved without other accessories, and the device is practical and convenient. After liquid discharging is finished, the main control circuit 5 controls the driving motor 11 to rotate the same revolution number in the anticlockwise direction, meanwhile, the real-time revolution number of the driving motor 11 is recorded by the revolution counter 14 and fed back to the main control circuit 5, after the revolution number is reached, the driving motor 11 stops rotating, at the moment, the liquid discharging pump finishes liquid suction, waits for the next induction triggering work, and enters a standby state. For the regulation of the liquid outlet amount, the rotation value of the driving motor 11 stored in the main control circuit 5 is changed by touching the regulating button for regulating the liquid outlet amount, so that the stroke of the reciprocating motion of the toggle pressure rod 13 is changed, the depth of the toggle pressure rod 13 for compressing the liquid outlet pump is changed, and the change of the liquid outlet amount is realized.

In the in-service use, this automatic play liquid device can be fixed on the wall, arrange the mesa in or arrange the support in, it fixes on a liquid ware through the fixed buckle 4 of bottle to go out liquid bottle 8, the fixed buckle 4 of bottle can be "C" font, half moon shape etc. is accurate in order to block out liquid bottle 8, and the fixed buckle 4 of bottle is movable on locating actuating mechanism 1's casing 121, and can dismantle, go out liquid bottle 8 to different specifications size and match, then need not change the liquid ware again when the play liquid bottle 8 of different models is changed to needs, it can to change the fixed buckle 4 of bottle that is suitable for, so just need not change the liquid ware again to the play liquid bottle 8 of different specifications, a large amount of resource cost has been saved. And simultaneously, the utility model discloses can realize that liquid directly flows out from going out liquid bottle 8, it can separate completely with automatic liquid device to go out liquid bottle 8, go out the liquid in the liquid bottle 8 and the inner structure of automatic liquid device contactless completely, liquid also need not through the automatic liquid device that goes out of class, can not cause the secondary pollution of liquid, and simultaneously, stir depression bar 13, bottle fixed buckle 4 is direct to be one with whole actuating mechanism 1, the during operation is accurate, and transmission assembly 12 and stir the lever principle that is laborsaving between the depression bar 13, the power loss to the motor is littleer, thereby operating current is little, the life of battery 7 and mechanical component has been increased.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
