Example 1

In the laboratory, the preparation of pure water mainly depends on a water purifier.

In order to prevent that laboratory can not have pure water to use during the water purification machine overhauls, influence the normal clear of experiment, chemical examination and detection etc. usually can set up the water storage box at the end of pure water pipeline, and the pure water in the water storage box needs the regular opening master valve to supply. If the pure water is used in a large amount, the pure water in the water storage tank is easily insufficient, and the opening of the main valve to supplement the pure water in the water storage tank needs to be attended, so that the water storage tank is very inconvenient to use. Moreover, the situation that the experimenters leave midway and do not close the valve in time, so that a large amount of pure water overflows and is wasted is extremely easy to occur.

In order to solve the above-described problems, referring to fig. 1, the present embodiment provides a water-using apparatus for pure water. The pure water device comprises a water storage tank 2, a water inlet pipeline 3 and a water outlet pipeline 4. The water storage tank 2 is provided with a water inlet and a water outlet.

One end of the water outlet pipeline 4 is connected with the water outlet.

When the pure water source is connected, pure water enters the water storage tank 2 through the water inlet pipeline 3, when the liquid level of the water storage tank 2 rises to a certain water level, the ball float valve 31 is in a first state, at the moment, the ball float valve 31 seals the water inlet pipeline 3, even if the pure water source is not closed in time, pure water cannot enter the water storage tank 2 through the water inlet pipeline 3, the automatic closing of the pure water is realized, and the waste of water resources caused by forgetting to close the water is avoided.

When water is needed, the water outlet component is opened, and pure water in the water storage tank 2 flows out through the water outlet pipeline 4 for experimental use. As the liquid level of the water storage tank 2 drops, so that the float valve 31 is in the second state, at this time, the water inlet pipe 3 is opened, and pure water enters the water storage tank 2 through the water inlet pipe 3 until the liquid level of the water storage tank 2 rises to a certain water level. The automatic water supplementing of the water storage tank 2 is realized, pure water is guaranteed to be stored in the water storage tank 2 all the time, and during the water stopping period, the pure water stored in the water storage tank 2 can be used for laboratory emergency.

In this embodiment, the water outlet assembly includes the shower head 41 and the pressing handle 42, the shower head 41 is provided at the other end of the water outlet pipe 4, and the pressing handle 42 can control the opening and closing of the shower head 41. When water is needed, the pressing handle 42 is pressed down, and the shower head 41 discharges water. When the water is used, the pressing handle 42 is released, the pressing handle 42 is automatically reset, and the shower head 41 is closed. Further prevent that the experimenter forgets to close the switch and cause the waste of pure water resource.

Preferably, the water outlet intensity of the shower head is adjustable. The water outlet intensity of the shower head is adjusted to meet the flushing demands of different intensities in a laboratory. When ordinary flushing is carried out, the shower head is regulated to be weak water strength; when some dirt with higher adhesion degree is washed, the shower head is regulated to have strong water strength.

Specifically, the water reservoir 2 is provided with a ventilation valve 21. The ventilation valve 21 can ensure the balance of the internal and external pressure differences of the water storage tank 2. The water storage tank 2 is prevented from being broken due to the fact that the pressure inside the water storage tank 2 is too high, or the water storage tank 2 is prevented from being deformed due to the fact that the pressure inside the water storage tank 2 is too low.

Further, a filter membrane is provided on the ventilation valve 21, and the filter membrane can isolate impurities. Dust and impurities in the air are prevented from entering the water storage tank 2, and pure water in the water storage tank 2 is ensured not to be polluted by external dust or impurities.

Preferably, the top of the water storage tank 2 is provided with an observation window 22, and the internal condition of the water storage tank 2 can be observed through the observation window 22. The water storage tank 2 is convenient for an experimenter to monitor, and the water storage tank can be timely processed when accidents occur.

When the pure water in the water storage tank 2 rises to be in contact with the floating ball, the floating ball can float along with the rising of the pure water liquid level due to the fact that the density of the floating ball is smaller than that of the pure water until the floating ball floats to the top surface of the valve body, and the water inlet pipeline 3 is blocked by the floating ball due to the fact that the diameter of the floating ball is larger than the inner diameter of the water inlet pipeline 3, and pure water cannot enter the water storage tank 2 through the water inlet pipeline 3. It is worth mentioning that the pure water prepared by the existing water purifier has slow flow rate and smaller pressure, so that the condition that the pure water rushes away the floating ball plugged on the water inlet pipeline 3 does not exist.

When the water outlet assembly is opened, pure water in the water storage tank 2 flows out, the liquid level of the pure water descends, and the floating ball descends along with the descending of the liquid level of the pure water until the floating ball returns to the bottom surface of the valve body, the water inlet pipeline 3 is opened, and the pure water flowing in from the water inlet pipeline 3 flows into the water storage tank 2 through the through hole on the valve body. With this circulation, automatic water storage and automatic shut-off of pure water are realized.

When the pure water in the water storage tank 2 rises to be in contact with the floating ball, the floating ball floats along with the rising of the pure water liquid level because the density of the floating ball is smaller than that of the pure water, and the blocking piece is driven to rise through the connecting rod until the blocking piece blocks the water inlet pipeline 3. At this time, pure water cannot enter the water storage tank 2 through the water inlet pipe 3. It is worth mentioning that the pure water prepared by the existing water purifier has slow flow rate and smaller pressure, so that the condition that the pure water rushes away the plugging piece plugged on the water inlet pipeline 3 does not exist.

When the water outlet assembly is opened, pure water in the water storage tank 2 flows out, the liquid level of the pure water descends, the floating ball descends along with the descending of the liquid level of the pure water, the blocking piece is driven to descend through the connecting rod, and the blocking piece stops blocking the water inlet pipeline 3. The water inlet pipe 3 is opened, and the pure water flowing in from the water inlet pipe 3 flows into the water storage tank 2 through the through hole on the valve body. With this circulation, automatic water storage and automatic shut-off of pure water are realized.

In the embodiment, the water purifier is provided with a pure water pipeline 1, a control main valve 11 is arranged on the pure water pipeline 1, and the pure water pipeline 1 is connected with one end of a water inlet pipeline 3 through a quick connection clamp 12. Because the quick connection clamp 12 can only meet the connection of two water pipes with the same pipe diameter, and the pipe diameter of the water inlet pipeline 3 is different from the pipe diameter of the pure water pipeline 1, the adapter 13 needs to be connected to one end of the water inlet pipeline 3, one side of the adapter 13 is the same as the pipe diameter of the water inlet pipeline 3, and the other side of the adapter 13 is the same as the pipe diameter of the pure water pipeline 1. The water inlet pipeline 3 connected with the adapter 13 is connected with the pure water pipeline 1 through the quick connection clamp 12, so that the tightness of the connection of the water inlet pipeline 3 and the pure water pipeline can be ensured, and water leakage is prevented.

Further, the control master valve 11 may be opened during the working hours, and the control master valve 11 may be closed during the working hours. Preventing the waste of pure water caused by special conditions.

The first embodiment is based on the first embodiment, and the structure of the water outlet assembly is changed.

In this embodiment, the water outlet assembly includes a water diversion pipe 43, the water diversion pipe 43 includes a water inlet end and a water outlet end, the water inlet end is connected to the other end of the water outlet pipe 4, the water outlet end is provided with a hose, and the hose is detachably provided with a water stop clip 46. When water is needed, the water stop clamp 46 is taken down, water in the water storage tank 2 can flow out along the water diversion pipe 43 and the hose, and when water is used, the water stop clamp 46 is clamped back to the hose.

Preferably, two water outlets are provided, one water outlet is provided with a first hose 44, the other water outlet is provided with a second hose 45, and the first hose 44 and the second hose 45 have different pipe diameters.
