Technical Field

The utility model relates to a technical field of aqueous cleaning specifically, relates to a water purification system.

Background

With the pursuit of the public on the quality of life, the water purifier gradually enters the families of people. Reverse osmosis water purifiers are becoming more popular because the purified water produced by them is fresher, more sanitary and safer.

Former aquatic has higher TDS (soluble solid total amount) more, and reverse osmosis water purification machine can block a large amount of ions in former aquatic before the osmotic membrane under the effect of high-pressure pump, and the pure water through the osmotic membrane can flow through the center tube. Meanwhile, the reverse osmosis filter element can discharge high-TDS concentrated water according to a certain proportion when the direct drinking water is prepared. Although the concentrated water can be discharged through the concentrated water pipeline, a small amount of concentrated water still remains in the reverse osmosis filter element after water production is finished. After a long shutdown, ions in the concentrate diffuse into the pure water, thereby contaminating the pure water stored in the central tube and downstream thereof.

In order to prevent concentrated water in the reverse osmosis filter element from polluting pure water, some existing reverse osmosis water purifiers are provided with a water tank and a flushing waterway. Pure water is stored in the water tank. The one end in washing water route is connected the water tank and the other end is connected to the water inlet of booster pump, is provided with check valve and solenoid valve etc. on the washing water route. When the water tank is in standby, the flushing time can be set, and the booster pump and the electromagnetic valve are started to flush the reverse osmosis filter element by utilizing the water in the water tank. However, the addition of an additional water tank and a flushing waterway leads to an increase in cost of the product and is disadvantageous to miniaturization of the product. Furthermore, this also makes the control circuit of the reverse osmosis water purifier complicated because the control circuit needs to consider when water is stored in the water tank, and the opening and closing of the solenoid valve and the booster pump, and the like.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

The utility model provides a water purification system 100, as shown in fig. 1, including booster pump 200 and reverse osmosis filter core 300, the delivery port of booster pump 200 communicates the raw water mouth 310 of reverse osmosis filter core 300. The water purification system 100 further comprises a water storage tank 400, a water outlet of the water storage tank 400 is directly communicated with the pure water outlet 320 of the reverse osmosis filter element 300, and the water storage tank 400 may comprise a water bag 410.

At least a portion of the water bladder 410 may be made of an elastic material, thereby being capable of changing the volume, and thus changing the volume of the water bladder 410 by its own elasticity. The elastic material may comprise, for example, a rubber material or a silicone material, etc. The water bladder 410 has a first volume and a second volume, wherein the first volume is less than the second volume. When the water bag 410 is filled with water, the water bag 410 increases from the first volume to the second volume, and the elastic potential energy of the water bag increases, so that the water bag has a trend of changing from the second volume to the first volume, and simultaneously, the water in the water bag 410 is extruded out. That is, when the pressure at the water outlet of the water storage tank 400 is reduced, the water bladder 410 releases its elastic potential energy, so as to facilitate the water bladder 410 to contract, and the volume of the water bladder 410 is reduced again.

In the water purification system, the water passing port of the water storage tank 400 is directly communicated with the pure water port 320 of the reverse osmosis filter element 300, the booster pump 200 is started, in the water production process, the pure water is filled into the water storage tank 400 by the pressure generated by the booster pump 200, the volume of the water bag 410 is increased, and the elastic member continuously stores elastic potential energy. After the booster pump 200 stops working, the elastic member releases the elastic potential energy due to no pressure for filling water into the water storage tank 400, and the water bag 410 contracts to squeeze out the pure water in the water bag 410. The discharged pure water can be returned to the reverse osmosis filter element 300 through the pure water port 320 of the reverse osmosis filter element 300 and discharged through the concentrate water port 330 of the reverse osmosis filter element 300, and in the discharging process, a concentrate pipeline inside the reverse osmosis filter element 300 and a concentrate pipeline of a water purification system can be flushed to prevent the concentrate from being left therein.

Therefore, the water purification system 100 with the structure can automatically extrude the pure water in the water storage tank 400 back to the reverse osmosis filter element 300 after stopping water production, discharge the concentrated water in the reverse osmosis filter element 300, and enable the pure water to be filled in the water storage tank, so that even if the water purification system 100 is in standby for a long time, the phenomenon that the ion concentration of the first cup of water taken by a user is too high due to the pollution of the concentrated water can be effectively avoided. Meanwhile, the water storage tank 400 can flush the reverse osmosis filter element 300 by means of the pressure of the water storage tank, so that a new water pump or a flushing water path is avoided, the design difficulty is reduced, the size of a product is reduced, and the cost of the product is also reduced.

Illustratively, the water storage tank 400 may further include elastic members 424, 424' disposed outside the water bladder 410. The elastic member 424, 424' has a first elastic potential energy when the water bladder 410 has a first volume. The elastic member 424, 424' has a second elastic potential energy when the water bladder 410 has a second volume. The first elastic potential energy is less than the second elastic potential energy.

The elastic member 424 may be a spring or other strip-like elastic body, etc. The form of the elastic member can be selected as desired by those skilled in the art. Various embodiments of the elastic member will be described in detail later.

In one embodiment, as shown in fig. 3, the water bladder 410 and the elastic member 424 may be two separate parts. The elastic member 424 may be, for example, a balloon. When the water pressure in the water bag 410 is increased, the water bag 410 will increase from the first volume to the second volume, and the water bag 410 will compress the elastic member 424, so that the elastic member 424 is compressed. The stored elastic potential energy of the elastic member 424 increases from the first elastic potential energy to the second elastic potential energy. When the water pressure in the water bag 410 is reduced, the elastic member 424 releases the elastic potential energy to compress the water bag 410, so that the water bag 410 is contracted.

In another embodiment, as shown in FIG. 4, which is similar to the embodiment shown in FIG. 3, the difference is the structure of the elastic member 424'. In this embodiment, the elastic member 424' may be a piston having a restoring member, and the water bladder 410 may push the piston to move. When the water pressure in the water bag 410 increases, the water bag 410 will increase from the first volume to the second volume, and the water bag 410 will compress the elastic member 424 'to compress the restoring element of the elastic member 424', and the stored elastic potential energy of the elastic member is increased from the first elastic potential energy to the second elastic potential energy. When the pressure in the water bag 410 is reduced, the restoring member of the elastic member 424' releases the elastic potential energy to compress the water bag 410, so that the water bag 410 is contracted.

It can be seen that, in the water storage tank 400 having the above structure, the pressing force to the water in the water bladder 410 can be provided not only by the water bladder 410 itself but also by the elastic members 424 and 424' outside the water bladder 410, so that the water in the water bladder 410 can be pressed out as much as possible, and the water in the water bladder 410 can rapidly flush the reverse osmosis filter element 300 due to the large pressing force.

Illustratively, the volume of the water bladder 410 is between 100 ml and 400 ml, such as 100 ml, 150 ml, 200 ml, 250 ml, 300 ml, 350 ml, 400 ml, and the like. Since the pure water stored in the water bladder 410 is not used for the user to take but is used for washing the reverse osmosis filter element 300, the amount of water stored therein does not have to be excessive, and the capacity thereof may be greater than or equal to the volume of the central tube of the reverse osmosis filter element 300.

In this way, the volume of the bladder 420 can be set within its fully utilized volume range, further controlling the size of the product.

Illustratively, the elastic member is configured such that it generates a pressure when the water bladder 410 stores water that is less than a pressure of water generated when the reverse osmosis cartridge 300 produces water. That is, the pressure of the water in the water bladder 410 pressed by the elastic member is less than the pressure of the water generated from the reverse osmosis filter cartridge 300. Therefore, the pure water generated by the reverse osmosis filter element 300 can enter the water bag 410 and expand the water bag 410, so that the water bag 410 can discharge the pure water after the water production is stopped.

Illustratively, as shown in fig. 2, the water storage tank 400 further includes a tank 430, and the water bladder 410 includes a bladder 411 and a port 412, and the bladder 411 and the port 412 may be an integrally formed piece or a separate piece, and are formed by welding or bonding. The bladder 411 is disposed in the tank 430, the bladder 411 is connected to the tank 430 through the port 412, and the port 412 may be provided with threads to connect the port 412 of the water bladder 410 to the tank 430 through a threaded connection. The water outlet of the water storage tank 400 is disposed at the connector 412, so that water can flow into the bladder 411 through the water outlet of the water storage tank 400 and the connector 412. The volume of the bag body 411 is only expanded by the water filled in the bag body, and the second elastic potential energy is generated when the bag body 411 is expanded to be larger than the volume of the bag body 411 when the water is not filled, and after the booster pump 200 stops water production, the water in the bag body 411 is extruded out and enters the reverse osmosis filter element without other devices.

It can be seen that the water storage tank 400 having the above structure is simple in structure and easy to install and maintain.

In embodiments where the resilient member 424 comprises a bladder, as shown in fig. 3, the bladder is disposed within the canister 430 and abuts the bladder 411, the bladder having a third volume when the water bladder 410 has the first volume and a fourth volume when the water bladder 410 has the second volume, the fourth volume being less than the third volume. In the water storage tank 400, when the reverse osmosis filter element 300 produces water, the volume of the water bag 410 is increased, the air bag is extruded, the volume of the air bag is reduced, and the elastic potential energy of the air bag is increased. When the reverse osmosis filter element 300 stops producing water, the gas in the air bag releases elastic potential energy to press the water bag 410 and discharge the water in the water bag 410 out of the water storage tank 400. The reason why the air bag is tightly close to the bag body 411 in the tank 430 is to allow the air bag and the water bag 410 to change their volumes at the first time, so as to avoid the air bag from expanding, but the volume of the water bag 410 is not changed, or the water bag 410 is expanded, but the air bag is not compressed. Meanwhile, the water storage tank 400 with the air bag structure can change the elastic potential energy thereof by changing the amount of gas in the air bag, thereby changing the water outlet pressure of the water storage tank 400.

The elastic member having the above structure has a simple structure, is easily installed in the water storage tank 400, is independently placed from the water bladder 410, and is easily maintained. But also can change the pressure of the air bag through the amount of the air bag filled with air, thereby increasing the application range of the water storage tank 400.

In one embodiment, as shown in fig. 1, the water purification system 100 includes a check valve 500, a high pressure switch 600 and a mechanical faucet 700, wherein a water outlet of the water storage tank 400 is communicated with a water inlet of the check valve 500, a water outlet of the check valve 500 is communicated with the mechanical faucet 700, and the high pressure switch 600 is disposed between the check valve 500 and the mechanical faucet 700.

When the user gets water through mechanical tap 700, mechanical tap 700's delivery port and atmosphere intercommunication, high-voltage switch 600 detects the pipeline pressure decline at the place, and high-voltage switch 600 switches on to send the water intaking electricity signal, after booster pump 200 received the water intaking electricity signal, start and begin to make water. When the user closes the mechanical tap 700 to stop taking water, pure water will enter the water bladder 410 of the water storage tank 400 because the booster pump 200 is still producing water, the pressure in the water bladder 410 rises, and the water bladder 410 expands to press the elastic member. When the high-voltage switch 600 detects that the pressure of the pure water port 320 reaches the disconnected pressure value, the high-voltage switch 600 is disconnected and sends a water taking stopping electric signal, and after the booster pump 200 receives the water taking stopping electric signal, the booster pump 200 stops working. At this time, since the high-pressure pure water is stored in the water bladder 410, the pure water port 320 is blocked from the outside by the user stopping water intake, and the pure water in the water bladder 410 is reversely flowed into the reverse osmosis filter element 300 under the pressure of the elastic member and is discharged from the concentrate port 330 of the reverse osmosis filter element 300. Until the pressure in the water bladder 410 is equalized with the atmospheric pressure, the water discharge operation is completed.

Therefore, in the water purification system 100 with the mechanical faucet 700, the problem that pure water behind the reverse osmosis filter element 300 is polluted by concentrated water after the water purification system 100 stops producing water is solved, and the ion concentration of the first cup of water taken by a user is prevented from being too high.

Illustratively, the water purification system 100 further comprises a first controller, the high-voltage switch 600 is electrically connected to the first controller, the first controller activates the booster pump 200 in response to an electrical signal when the high-voltage switch 600 is closed, and the first controller deactivates the booster pump 200 in response to an electrical signal when the high-voltage switch 600 is open.

The water purification system 100 with the first controller can better control the booster pump 200, and improve the user experience.

Illustratively, the water purification system 100 further includes a concentrate solenoid valve 800, a water inlet of the concentrate solenoid valve 800 is connected to the concentrate port 330 of the reverse osmosis cartridge 300, a first controller is electrically connected to the concentrate solenoid valve 800, the first controller opens the concentrate solenoid valve 800 in response to an electrical signal of the high voltage switch 600 being turned off and closes the concentrate solenoid valve 800 after a first predetermined period of time.

When the high-voltage switch 600 is turned off, the booster pump 200 stops water production, at this time, water in the water bag 410 in the water storage tank 400 flows back to the reverse osmosis filter element 300 through the pure water port 320, the first controller controls the concentrated water electromagnetic valve 800 to be opened, and pure water entering the reverse osmosis filter element 300 enters from the pure water port 320 and is discharged from the concentrated water port 330. The first controller may further set a time for closing the concentrated water solenoid valve 800, where the time may be a time for discharging water from the water bag 410 to the reverse osmosis filter element 300, for example, 1s, 2s, 3s, 4s, 5s, and the like, and after the water in the water bag 410 flushes the reverse osmosis filter element 300, the first controller controls the concentrated water solenoid valve 800 to close.

Thus, the discharged concentrate can be prevented from flowing backward into the reverse osmosis filter 300, causing secondary pollution of the reverse osmosis filter 300.

In another embodiment, as shown in fig. 5, the water purification system 100' further comprises an electrically controlled faucet 900 and a second controller, the water outlet of the water storage tank 400 is communicated with the electrically controlled faucet 900, the second controller activates the booster pump 200 in response to a water intake signal sent by the electrically controlled faucet 900, and the second controller shuts off the booster pump 200 after a second predetermined period of time in response to an electrical signal for shutting off the electrically controlled faucet 900.

When a user opens the electric control faucet 900 to start water taking, the electric control faucet 900 sends a water taking electric signal to the second controller, and the second controller starts the booster pump 200 to start water making after receiving the water taking electric signal. When the user stops taking water, the electric control faucet 900 is turned off, and a water taking stop signal is sent to the second controller, and after the second controller receives the water taking stop signal, the second controller may perform control of stopping the booster pump 200 with a delay, that is, turn off the booster pump 200 after a set time, for example, 1s, 2s, and the like. During the time period from the closing of the electrically controlled faucet 900 to the stopping of the booster pump 200, the booster pump 200 continues to produce water, but since the water outlet of the faucet is closed, the produced water enters the water bag 410, the water bag 410 expands, the pressure in the water bag 410 is increased, the water storage amount is increased, and the elastic member is squeezed. At this time, the pressure inside the water bladder 410 is higher than the atmospheric pressure.

After the predetermined time of the second controller is reached, the booster pump 200 stops working. At this time, since the high-pressure pure water is stored in the water bladder 410, the pure water port 320 is blocked from the outside by the user stopping water intake, and the pure water in the water bladder 410 is reversely flowed into the reverse osmosis filter element 300 under the pressure of the elastic member and is discharged from the concentrate port 330 of the reverse osmosis filter element 300. Until the pressure in the water bladder 410 is equalized with the atmospheric pressure, the water discharge operation is completed.

Therefore, in the water purification system 100' with the electric control faucet 900, the problem that pure water behind the reverse osmosis filter element 300 is polluted by concentrated water after the water purification system 100 stops producing water is solved, and the phenomenon that the ion concentration of the first cup of water taken by a user is too high is avoided.

Illustratively, the water purification system 100' further includes a concentrate solenoid valve 800, a water inlet of the concentrate solenoid valve 800 is connected to the concentrate port 330 of the reverse osmosis cartridge 300, a second controller is electrically connected to the concentrate solenoid valve 800, the second controller opens the concentrate solenoid valve 800 after a second predetermined period of time and closes the concentrate solenoid valve 800 after a third predetermined period of time in response to an electrical signal that the electrically controlled faucet 900 is closed.

When the user stops getting water and closes the electric control faucet 900, the booster pump 200 will continue to work between the ends, i.e. the second predetermined time, during which the pure water prepared by the reverse osmosis filter element 300 will be filled into the water bag 410, so that a certain pressure is generated in the water storage tank 400. After the second preset time is reached, the second controller will open the concentrated water solenoid valve 800. The water in the water bladder 410 will flush the reverse osmosis cartridge 300 and be discharged through the concentrate outlet 330, as described above.

The third predetermined time set by the second controller is the time when the concentrated water solenoid valve 800 is closed, which may be the time when the water bag 410 drains the reverse osmosis filter element 300, for example, 1s, 2s, 3s, 4s, 5s, and the like, and after the water in the water bag 410 finishes flushing the reverse osmosis filter element 300, the second controller controls the concentrated water solenoid valve 800 to close.
