Fig. 3 is attachment structure figure of the float on buffer pool in the utility model.
Embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, fluid infusion bubble backflow mechanism is prevented in a kind of liquid crystal panel etching system of the utility model,
Including input duct 11, drain pipe road 12, magnetic valve 13, flowmeter 14, float 15, switch and provided with inlet and liquid outlet
Buffer pool 16, the connection corresponding with the inlet and liquid outlet of buffer pool 16, electromagnetism respectively of input duct 11 and drain pipe road 12
Valve 13 and flowmeter 14 are all connected on drain pipe road 12, and magnetic valve 13 is located between buffer pool 16 and flowmeter 14.Switch
On the inwall of buffer pool 16, and switch is connected by wire with magnetic valve 13, and float 15 is in buffer pool 16, and float
15 one end is connected to switch above and opens switch.
Chute 160 is provided with the inwall of buffer pool 16, one end of float 15 is slidably connected in the chute 160.Switch
Located at the top of the chute 160.
For preferably float 15 is defined in chute 160, stopper slot 161 is provided with the inwall of chute 160.
Float 15 in the utility model includes base 151, support bar 152, adjusting rod 153 and sliding block 154, support bar
152 are perpendicularly fixed on base 151, one end of adjusting rod 153 by bolted splice on support bar 152, the other end and sliding block
154 are fixedly connected.Sliding block 154 is slided in chute 160, is provided with and is mutually fitted with the stopper slot 161 on the side wall of sliding block 154
The spacer pin 155 matched somebody with somebody.
Drain pipe road 12 in the utility model is connected with cleaning the shower nozzle of glass substrate, and liquid crystal panel is placed under shower nozzle
Processing is performed etching in the decoction cell body of side, when in use, fluid infusion, buffer pool are carried out into buffer pool 16 by input duct 11
Liquid surface level in 16 is high, and float 15 is floated on liquid level, and the one end of float 15 is connected to switch above and opens switch, now electric
Magnet valve 13 is opened, and the liquid in buffer pool 16 enters in drain pipe road 12, and the bubble produced during fluid infusion can float over liquid table
