Description
Technical field
A kind of water device that changes that the utility model relates to biological technical field when changing water (cleaning fluid), what particularly be used to carry out to change when spotting needle cleans water (cleaning fluid) changes the water device.
Background technology
At present, change the needs of water (cleaning fluid) in purchasing in order to adapt to biochip, some developed countries have researched and developed in succession and have changed the water device.There is following shortcoming in the said equipment:
1, these devices all need certain power when changing water, as peristaltic pump etc., by the mode of peristaltic pump squeezing tube water (cleaning fluid) are clamp-oned when changing water and are extruded aqua storage tank (rinse bath).Because need continuous squeezing tube, flexible pipe is easy to be caused leakage by squeeze crack.Because water inlet and water outlet respectively need a peristaltic pump, the volume that has so not only increased product has also increased cost simultaneously in addition.
2, aspect control system,, increased the difficulty of control owing to need control peristaltic pump by the serial ports of peristaltic pump.
The utility model content
The purpose of this utility model is to overcome the existing defective that the water device exists of changing, and what a kind of new structure was provided changes the water device, and the gravity that utilizes liquid is as power, thereby makes liquid reach the purpose of changing water by the gravity inflow and outflow reservoir of self.
The utility model is simple in structure, and is easy and simple to handle, stable performance, and power saving saves time; Have more practicality, can increase economic efficiency greatly, therefore have industrial utilization.
It is to adopt following scheme to realize that the utility model solves its technical problem underlying: the utility model mainly is made up of an aqua storage tank, a water purifying bottle, a waste water bottle and two solenoid valves; Aqua storage tank is provided with water inlet pipe, rising pipe and run-down pipe.The water inlet pipe of aqua storage tank links to each other with water purifying bottle by a solenoid valve; Rising pipe links to each other with the waste water bottle by a solenoid valve; Run-down pipe inserts the waste water bottle by flexible pipe, and water purifying bottle and waste water bottle place the position above and below aqua storage tank respectively.
The internal diameter of aqua storage tank run-down pipe is greater than the water inlet pipe internal diameter.The height of the run-down pipe of aqua storage tank is lower than the height of aqua storage tank.
Solenoid valve is an one-way valve.
Principle of work of the present utility model is as follows with the course of work: when the energising of the solenoid valve that is connected with water inlet pipe, solenoid valve is opened, and aqua storage tank begins water inlet, should guarantee that generally water-head more than 40 centimetres is to guarantee certain flow velocity; When the solenoid valve that is connected with rising pipe was switched on, solenoid valve was opened, and aqua storage tank begins draining.
Water purifying bottle of the present utility model is arranged in the position that is higher than aqua storage tank, and the bottom of water purifying bottle should be higher about 50 centimetres than the bottom of aqua storage tank, to guarantee certain water intake velocity; The waste water bottle places the position that is lower than aqua storage tank.Open the solenoid valve that water inlet links to each other with water delivering orifice, water can rely on self gravitation to enter and flow out aqua storage tank.
The water constant height of aqua storage tank of the present utility model, each water enter the water that is higher than the run-down pipe height behind the aqua storage tank and can flow out from run-down pipe, guarantee that liquid level is constant, simplify the structure and have reduced cost.
The internal diameter of the utility model aqua storage tank run-down pipe is greater than the internal diameter of water inlet pipe, and generally the former is bigger 3 millimeters or 10% than the latter, gets higher value.To guarantee that under the too much situation of intaking, water can be discharged and can not caused water to overflow aqua storage tank from run-down pipe at once.
The utility model moves without any the machinery of parts except that two solenoid valves, and the noise when both having reduced work has also reduced the possibility that instrument breaks down.
The utility model is realized water inlet by control entering water electromagnetic valve power on/off, realizes draining by control drain solenoid valve power on/off, and this to change the water apparatus structure simple, can significantly reduce cost and then increase economic efficiency.
It is simple that the utility model changes the water apparatus structure, easy and simple to handle.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Wherein: water purifying bottle 1, entering water electromagnetic valve 2, water inlet pipe 3, aqua storage tank 4, run-down pipe 5, drainpipe 6, drain solenoid valve 7, waste water bottle 8.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further specified.
As shown in drawings, the utility model is made up of 3 water receptacles, and it mainly comprises: water purifying bottle 1, waste water bottle 8 and aqua storage tank 4.Water purifying bottle 1 places the position that is higher than aqua storage tank 4, and waste water bottle 8 is lower than the height of aqua storage tank 4.Water purifying bottle 1 links to each other with the water inlet pipe 3 of aqua storage tank with entering water electromagnetic valve 2 by flexible pipe; Waste water bottle 8 links to each other with the drainpipe 6 of aqua storage tank with drain solenoid valve 7 by flexible pipe, inserts waste water bottle 8 with the run-down pipe 5 connection flexible pipes of aqua storage tank 4 and with flexible pipe.
During work, make entering water electromagnetic valve 2 energisings, this moment, entering water electromagnetic valve 2 will be opened, water flows into aqua storage tank 4 from water purifying bottle 1, after after a while (because the internal diameter of the difference in height between water purifying bottle 1 and the aqua storage tank 4, water pipe and aqua storage tank 4 volumes is different, time is difference to some extent) entering water electromagnetic valve 2 outage, entering water electromagnetic valve 2 will be closed and stop into water.If when water inlet, the water level in the aqua storage tank 4 is higher than the height of run-down pipe 5, this moment, water can flow into waste water bottle 8 through flexible pipe from run-down pipe 5.During draining, make drain solenoid valve 7 energisings, drain solenoid valve 7 will be opened, water flows into waste water bottle 8 from aqua storage tank 4, after after a while (because the internal diameter of the difference in height between waste water bottle 8 and the aqua storage tank 4, water pipe and aqua storage tank 4 volumes is different, time is difference to some extent) make drain solenoid valve 7 outages, drain solenoid valve 7 is closed and is stopped draining, so finishes a working cycle.
