Preferably, as shown in fig. 2, the water purifier according to the embodiment of the present invention further includes a pre-filter 17, and the pre-filter 17 is disposed between the second end of the water supply pipe 2 and the booster pump 4. For example, the number of the front filter elements 17 can be multiple, and the front filter elements 17 are sequentially connected in series, so that the water purifier according to the embodiment of the utility model can primarily filter water entering the reverse osmosis core 1 through the front filter elements 17, thereby further improving the water purification effect and prolonging the service life of internal pipelines and various components of the water purifier.

In some embodiments, as shown in fig. 1 and fig. 2, the water storage device 5 further has a power chamber 501 therein, the total volume of the power chamber 501 and the water storage chamber 502 is fixed, and the volume ratio of the power chamber 501 to the water storage chamber 502 is variable. Therefore, the water purifier provided by the embodiment of the utility model can change the water pressure in the water storage device 5 through the change of the volume ratio of the power cavity 501 to the water storage cavity 502, so that the purposes of water storage and drainage are achieved, and the convenience degree of the water purifier in use is further improved.

For example, the water storage device 5 includes a pressure barrel and an air bag, the air bag is arranged in the pressure barrel, the inner cavity of the pressure barrel forms the water storage cavity 502, and the inner cavity of the air bag forms the power cavity 501. It is understood that a gas-filled bladder is disposed within the water storage chamber 502. When water is stored in the water storage cavity 502, the air bag is gradually squeezed, and the pressure in the air bag is increased. When the water in the water storage cavity 502 needs to be discharged to the external water path, the pressure in the air bag is converted into driving force to push the water in the water storage cavity 502 to be discharged. Therefore, the water purifier provided by the embodiment of the utility model can generate power for discharging water in the water storage cavity 502 through the air bag, so that the water storage and the water discharge of the water storage device 5 are facilitated, and the water purifier is simple in structure and convenient to operate.

The water purifier provided by the embodiment of the utility model can change the volume ratio of the power cavity 501 to the water storage cavity 502 by moving the piston 503, so that the water storage and drainage of the water storage device 5 are facilitated.

Preferably, as shown in fig. 2, the power chamber 501 is connected to the water supply pipe 2 by a water pipe 18. The power chamber 501 drives the piston 503 to move by the water pressure of the water from the water supply pipe 2, thereby providing power to discharge the water in the water storage chamber 502. Therefore, the power provided by the power cavity 501 is relatively stable, and the water outlet speed of the water storage cavity 502 can be conveniently controlled in the process of discharging the purified water from the water storage cavity 502. In addition, the water purifier provided by the embodiment of the utility model can discharge purified water in the water storage cavity 502 more thoroughly by using the piston 305, so that more purified water is prevented from being left in the water storage cavity 502, and the utilization rate of the purified water is improved.

In some embodiments, as shown in fig. 1 and 2, the water purifier further comprises an electric control faucet 13, and the electric control faucet 13 is connected to the second end of the water intake pipe 3. The water purifier provided with the electric control faucet has clear control logic and is easy to realize the automatic operation of the water purifier.

In other embodiments, the water purifier can further comprise a mechanical faucet, and the starting and the standby of the water purifier can be controlled by opening and closing the mechanical faucet, so that the water purifier is simple and feasible, and the applicability of the water purifier is expanded.

In some embodiments, as shown in fig. 1 to 6, the water purifier further comprises a pressure switch 10, and the pressure switch 10 is disposed on the water intake pipe 3 and located between the second end of the water intake pipe 6 and the second end of the water intake pipe 3. For example, the pressure switch 10 is opened and closed according to the pressure value in the water intake pipe 3, so as to send a signal for starting or stopping the booster pump 4, and/or send a signal for opening or closing the first electromagnetic valve 8, so that the water purifier according to the embodiment of the present invention can automatically open or close the first electromagnetic valve 8 according to the pressure of the water intake pipe 3, thereby improving the automatic operability of the water purifier according to the embodiment of the present invention.

For example, the water pressure applied to the water purifier is usually 0.1-0.4Mpa, and it can be understood that, in order to store purified water in the water storage device 5 (also referred to as a pressure barrel), the pressure value of the pressure switch 10 which is turned off is greater than 0.4, otherwise, the piston 503 cannot move. Therefore, preferably, the pressure switch 10 is closed when the pressure of the water intake pipe 3 is 0.15 ± 0.05Mpa, and is opened when the pressure of the water intake pipe 3 is 0.5 ± 0.05Mpa, thereby further improving the stability of the operation of the water purifier.

Further, the water purifier according to the embodiment of the present invention further includes a controller (not shown) connected to the booster pump 4 and the first solenoid valve 8, and configured to control the start and stop of the booster pump 4 and the opening and closing of the first solenoid valve 8.

Further, the controller may also control the booster pump 4 and the first solenoid valve 8 based on an electric signal for stopping water intake from the electrically controlled faucet. For example, the controller may control the booster pump 4 and the first solenoid valve 8 based on an electric signal for stopping water intake received from an electric faucet, by timing or determining the amount of water stored to be supplied into the water storage chamber 502, or the like. In other words, the preset condition for the water purifier to control the booster pump 4 to stop may be that the controller determines, after receiving the electric signal for stopping water intake from the electric faucet and by a timing operation, that a time threshold has been reached since receiving the electric signal for stopping water intake, or that the water storage amount has reached a water amount threshold, so as to improve the sensitivity and accuracy of the water purifier according to the embodiment of the present invention in use.

In some embodiments, as shown in fig. 1 to 6, the water purifier according to the embodiment of the present invention further includes a TDS detector 12, the TDS detector 12 is disposed on the water intake pipe 3, and the TDS detector 12 is configured to detect a total dissolved solids content of the purified water in the water intake pipe 3. The controller is connected with the TDS detector 12 to control the first electromagnetic valve 8 to be opened and closed according to the detection value of the TDS detector 12, so that the water purifier provided by the embodiment of the utility model can adjust the flushing time and the flushing frequency of the reverse osmosis filter membrane 104 according to the detection value of the TDS detector 12, and the water purification quality of the water purifier is further improved.

Optionally, the water purifier further includes a timer (not shown), the controller is connected to the timer, and the controller can control the first electromagnetic valve 8 according to the timing duration or the timing time point of the timer, so that the water purifier according to the embodiment of the present invention can control the flushing time and the flushing frequency for flushing the reverse osmosis membrane 104 according to the timing time point or the timing duration of the timer, thereby further improving the water purification quality of the water purifier. It can be understood that, after the time threshold value of time-recorder arrived, the time-recorder transmitted the signal of telecommunication for the controller, then controller control first solenoid valve 8 opened, control booster pump 4 starts, the purifier began to make water, and carry out the water storage through water storage device 5, when treating the water storage to a definite value, for example, when the pressure in intake pipe 3 and oral siphon 6 reached a definite value, pressure switch 10 produced the signal, controller control booster pump 4 shut down and first solenoid valve 8 closes, and then water storage device 5 sent the water of water storage chamber 502 into reverse osmosis filter core 1, in order to wash reverse osmosis filter membrane 104.

The controller can upload the use habit time of the user to the cloud server. Can utilize the controller to control the purifier through high in the clouds server and start booster pump 4 in order to prepare the water purification before 8 am to open first solenoid valve 8 and carry out the automatically cleaning of purifier, thereby guaranteed the purification quality that the user got the water after opening the purifier. In addition, the water taking time of the user can be recorded and analyzed through the cloud server, so that the reverse osmosis filter membrane 104 can be automatically washed before the user takes water according to the recorded and stored water taking time, and the water purification quality of the cup water of the water purifier is further improved.
