DETAILED DESCRIPTION

[0028] The embodiments of the utility model will be described below through specific examples. Those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. The utility model can also be implemented or applied through different specific embodiments, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model.

[0029] Example 1, please refer to Figs. 1-3 :

[0030] An automatic inductive liquid spraying device comprises an outer shell 100, a liquid spraying bottle 200, an inductor 300, an electric push rod 400 and a control switch 500.

[0031] The outer shell 100 is in a cubic structure as a whole, and is internally provided with a cavity 110. The front surface of the outer shell 100 is provided with a material extension opening leading to the cavity 110. The liquid spraying bottle 200 is placed in the cavity 110, and the liquid spraying bottle 200 is used for containing lubricating oil or alcohol and other processing liquids. The top of the liquid spraying bottle 200 is provided with a pressing spout 210 (the pressing spout 210 is a mature structure, which is commonly seen on bottled shower gel).

[0032] The top of the outer shell 100 is provided with a mounting groove 600 arched on the upper surface of the outer shell 100. The control switch 500 and the electric push rod 400 are integrally mounted in the mounting groove 600. The inductor 300 is mounted on the inner side wall of the outer shell 100 close to the material extension opening position. The inductor 300 specifically adopts an HC-SR505 induction module and is used to generate a trigger signal when an external object extends into the cavity 110. The inner side wall of the outer shell 100 is further provided with a wiring groove 130 leading to the mounting groove 600. The inductor 300 is connected with a signal line extending along the wiring groove 130 into the mounting groove 600 and signal-connected with the control switch 500, and is used to output the trigger signal to the control switch 500. The control switch 500 adopts an SRC24vdcslc relay and is signal-connected with the electric push rod 400, and is used to control the electric push rod 400 to be powered on to start when the trigger signal is received. The active end of the electric push rod 400 is connected with a pressing plate 700 extending into the cavity 110 and located directly above the pressing nozzle 210. The electric push rod 400 is used to push the pressing plate 700 to move in the vertical direction until the pressing plate 700 presses the pressing nozzle 210 when the electric push rod 400 is powered on to start.

[0033] The outer shell 100 is further provided with spring mounting grooves 120600 symmetrically arranged on two inner side walls. The pressing plate 700 is provided with positioning protrusions 710 clamped in the spring mounting grooves 120600 at two ends. The positioning protrusions 710 arranged at two ends of the pressing plate 700 achieve position positioning during movement. The spring mounting grooves 120600 are further provided with reset springs 121 extending in the vertical direction. One end of the reset spring 121 abuts against the bottom wall of the spring mounting groove 120600, and the other end abuts against the lower side of the positioning protrusion 710.

[0034] By adopting the technical scheme, the workpiece to be processed is extended into the cavity 110 through the material extension opening. At this time, the inductor 300 senses the workpiece to generate a trigger signal. The control switch 500 reads the trigger signal to drive the electric push rod 400 to push the pressing plate 700 downward until the pressing plate 700 moves to press the pressing nozzle 210. The processing liquid is sprayed from the pressing nozzle 210. Thus, the automatic spraying of the processing liquid on the surface of the workpiece is achieved. Therefore, the processing efficiency is improved. Since the stroke of the electric push rod 400 can be pre-set, the amount of the processing liquid sprayed each time can be kept basically consistent. Therefore, the accuracy of the amount of the processing liquid is improved. After the processing is completed, the workpiece is moved out. At this time, the electric push rod 400 exits from the powered-on state. The electric push rod 400 is reset under the action of the reset spring 121. In practice, some electric push rods 400 can be configured to have the automatic reset function, but occasionally, the reset failure may occur. The structure of the reset spring 121 can effectively avoid the automatic reset failure of the electric push rod 400.

Even if various changes are made to the present application, if the changes fall within the scope of the claims of the present application and equivalent technologies thereof, they still fall within the scope of the present application.
