Refer to Fig. 1 to Fig. 7, the course of work of the present invention is as follows:
When the water level in bathtub surpasses A position, water in bathtub is plugged in a certain amount of gas in described tracheae 10, in this case, described pressure sensor 4 is converted into the signal of telecommunication by gas pressure, described controller 2 (is equivalent to gas pressure and is greater than preset value) when the described signal of telecommunication is greater than preset value, and produces first signal, and this first signal is transferred to described drive unit, drive unit is opened the filler block 309 that is positioned at bath base, carries out draining.In the process of draining, owing to being provided with protecting component 9 in described tracheae 10, and the area sum of the air vent 91 of protecting component 9 is less than the sectional area of tracheae 10, so, air pressure in the air bag of pressure sensor 4 can not reduce and cause negative pressure moment, water level in bathtub is during lower than A position, described pressure sensor 4 produces the signal of telecommunication, controller 2 receives these signals of telecommunication and can judge that the described signal of telecommunication is less than preset value (be equivalent to gas pressure and be less than preset value) and produce secondary signal and secondary signal is transferred to described drive unit, drive unit cuts out filler block, in this case, because the area sum that is provided with the air vent 91 of protecting component 9 and protecting component 9 in tracheae 10 is less than the sectional area of tracheae 10, can be understood as, if there is air to enter air bag from air chamber C, air is equivalent to enter passage aisle from major path, in other words, arranging of air vent 91 stoped portion of air to enter described air bag, so, the air entering in air bag is few compared with the mode that protecting component 9 is not set, can not make the air pressure moment in the air bag of described pressure sensor 4 become large, and then, pressure sensor 4 can not produce the signal of telecommunication, described filler block 309 yet can not opened and carry out drain operation, avoided the maloperation of pressure sensor 4.
In the present embodiment, described A position is protection water level, and B position is flood level.In the process of bathtub 300 water fillings, some water enter the bottom of air chamber 50 from tracheae 10, the water that enters air chamber 50 bottoms is just plugged in a certain amount of air in air chamber 50, along with the rising/reduction of the water level in bathtub 300, the hydraulic pressure of bathtub 300 bottoms just increases accordingly/reduces, thereupon, air pressure in air chamber 50 increases/reduces, the size of this air pressure and variation are measured to level sensor 5 by tracheae 10 conduction, thereby, just can reflect the measurement to bathtub 300 flood level B.Level sensor 5 is converted into the signal of telecommunication to controller 2 by the hydraulic pressure recording, and then 2 pairs of electromagnet 6 of controller are controlled and made it open filler block 309.In the situation that control panel 3 is opened, when water filling surpasses flood level B, level sensor 5 actions, control electromagnet 6 by electrical signal transfer to controller 2 by transmission line of electricity 11 described filler block 309 are opened, outfall 303 is opened and is discharged water, and water level declines.When water level is during lower than the about 1cm of flood level B, level sensor 5 sends the signals of telecommunication to electromagnet 6 power-off, and filler block 309 is closed.
