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.

After the long-time standby of purifier, the higher ion in the former aquatic of reverse osmosis membrane front TDS (soluble solid total) of reverse osmosis filter core can spread in the pure water in the membrane bag, leads to the TDS of the first cup of water that the user received when the purifier was opened next time too high. In order to avoid the problem, the utility model provides a purifier that is used for water storage device of purifier and has it. Fig. 1 shows a schematic water path diagram of a water purifier according to a first embodiment of the present invention, and arrows shown in the diagram schematically show the flow direction of water flow. Adopted in figure 1 the utility model provides a water storage device, of course, the utility model provides a water storage device can also be applied to arbitrary suitable purifier.

As shown in fig. 1, the water purifier 100 may include a booster pump 120, a reverse osmosis cartridge 130, a reflux solenoid valve 140, a waterway switching device 200, and a water storage device 300.

The water outlet of the booster pump 120 may be communicated to the raw water inlet of the reverse osmosis filter element 130, and the booster pump 120 delivers the boosted water to the reverse osmosis filter element 130. Optionally, a water inlet solenoid valve 110 may be further disposed upstream of the booster pump 120. The water inlet solenoid valve 110 is opened when the booster pump 120 is operated, and is closed when the booster pump 120 is stopped to cut off the water path. The water inlet solenoid valve 110, the booster pump 120, and the reverse osmosis cartridge 130 may employ various types of solenoid valves, booster pumps, and reverse osmosis cartridges that are known in the art or may come into existence in the future. It should be noted that only the reverse osmosis membrane may be disposed in the reverse osmosis filter element 130; optionally, the reverse osmosis filter element 130 may also be a composite filter element formed by combining a reverse osmosis membrane and other filter materials.

The waterway switching device 200 may have a first passage 210 and a second passage 220. The waterway switching device 200 may control the first channel 210 or the second channel 220 to be conducted. That is, the first path 210 and the second path 220 can only be conducted alternatively, and when the first path 210 is conducted, the second path is closed; when the first path 210 is closed, the second path 220 is turned on. The pure water outlet of the reverse osmosis cartridge 130 may be communicated to the water inlets of the first and

second passages

210 and 220.

The water storage device 300 may have a first chamber 310, a second chamber 320, a first water passing port 311, a second water passing port 321, and a partition 330. The first chamber 310 may communicate with the first drain port 311. The second capacity 320 may communicate with the second drainage port 321. The first drainage port 311 may be located at any suitable position on the first receptacle 310. The second drainage port 321 may be located at any suitable position on the second volume 320. The first and second receiving

chambers

310 and 320 may be partitioned into chambers that are not communicated with each other by a partition 330. The divider 330 is movable towards both the first and

second compartments

310, 320 to vary the longitudinal dimension of the first and

second compartments

310, 320. The longitudinal direction is a direction in which the partition 330 moves toward the first and

second cavities

310 and 320. The cross-sectional area of first volume 310 may be greater than the cross-sectional area of second volume 320. The cross section is a section formed by sectioning the first and

second cavities

310 and 320 in a direction perpendicular to the longitudinal direction. The cross-sectional area of first volume 310 at various locations thereof may be the same or different, and/or the cross-sectional area of second volume 320 at various locations thereof may be the same or different. First cavity 310 and second cavity 320 may be a single piece, as will be described in more detail below. Alternatively, first cavity 310 and second cavity 320 may be two separate pieces independent of each other.

The first water passing opening 311 may be communicated to the water outlet of the first passage 210 and the water outlet end of the water purifier 100. When in use, the water outlet end of the water purifier 100 can be connected to various water intake devices 400, such as a faucet, a pipeline machine, etc. The second water passing port 321 may be communicated to the water outlet of the second passage 220 and the water inlet of the return solenoid valve 140, respectively. The water outlet of the return solenoid valve 140 may be communicated to the water inlet of the booster pump 120.

After the water purifier 100 is in standby for a long time, the first section of water with higher TDS is stored in the reverse osmosis filter element 130. When the user takes the next water, the booster pump 120 can preferentially pump this first stage of higher TDS water through the second passage 220 into the second volume 320. Since the water intake device 400 is opened at this time, the water pressure in the first cavity 310 is low; meanwhile, the water pressure in the second chamber 320 is high by the booster pump 120, and the partition 330 moves from the second chamber 320 toward the first chamber 310 by the water pressure. The partition 330 may be moved a distance from the second compartment 320 towards the first compartment 310 when the first section of water with higher TDS enters the second compartment 320. Although the increased longitudinal dimension of second volume 320 is the same as the decreased longitudinal dimension of first volume 310 during movement of divider 330, first volume 310 may flow more water relative to the water entering second volume 320 due to the larger cross-sectional area of first volume 310 than the cross-sectional area of second volume 320. Thus, the water outlet flow of the water purifier 100 is enhanced. In addition, because the first chamber 310 is filled with the pure water prepared in advance after the last user stops taking water, the pure water is not the first section of water prepared by the reverse osmosis filter element 130 after the water purifier 100 is in standby for a long time, the TDS of the pure water is low, and the use requirement of the user is met.

When the partition 330 is moved from the second volume 320 toward the first volume 310 to a desired position, for example, to the end of the first volume 310, pure water of the first volume 310 has completely flowed out; or to a position where the volume of first receptacle 310 is reduced by one-half, etc. Through reasonable setting, the higher water of TDS that purifier 100 standby produced at this moment is whole to flow into in second appearance chamber 320 from the pure water outlet of reverse osmosis filter core 130, and the pure water of reverse osmosis filter core 130 refabrication has met operation requirement. At this time, the first passage 210 is turned on, and the booster pump 120 can pump the pure water to the water outlet end of the water purifier 100.

When the user takes water, during the first passage 210 is open, the return solenoid valve 150 is closed to ensure water flow at the outlet end. After the user stops the water intaking, can open backward flow solenoid valve 150, the higher first section water of TDS can be by in the booster pump 120 pump reverse osmosis filter core 130 in the second appearance chamber 320, through reverse osmosis filter core 130's filtration back, its TDS accords with the standard, supplies with the user and uses. At this time, since water in second chamber 320 is pumped out by booster pump 120 and pure water enters first chamber 310, the water pressure in first chamber 310 is higher than that in second chamber 320. Under the action of water pressure, the partition 330 moves from the first cavity 310 to the second cavity 320, so that pure water can be replenished into the first cavity 310, and before the next water intake, the water in the first cavity 310 is ensured to be sufficient to prepare for the next water intake. Through reasonable setting of the volumes and sizes of the first and

second chambers

310 and 320, pure water in the first chamber 310 can flow out when the first section of water with higher TDS in the reverse osmosis filter element 130 flows into the second chamber 320. This optimizes the volumes of the first and

second chambers

310 and 320 and reduces the size of the water storage device.

Therefore, the utility model provides a water storage device 300 has first appearance chamber 310 and second and holds chamber 320, and first appearance chamber 310 supplies water to the play water end of purifier 100, and the second holds the higher first section water of TDS of chamber 320 receipt, and the second holds chamber 320 and extrudes the pure water of first appearance chamber 310 through separator 330, and then ensures to carry the TDS conform to the standard of user's water. Furthermore, since the cross-sectional area of first volume 310 is larger than the cross-sectional area of second volume 320, more water may flow out of first volume 310 relative to the water entering second volume 320. Thus, the water outlet flow of the water purifier 100 is enhanced.

Therefore, the water purifier 100 adopting the water storage device 300 can effectively prevent a user from receiving water with higher TDS, and ensure the water safety of the user; meanwhile, the water storage device 300 can also increase the water outlet flow of the water purifier 100, reduce the time for a user to take water, and achieve better use experience.

Preferably, the water storage device 300 may further include a cylinder 340 and a telescopic member 350. The partition 330 is movably disposed within the cylinder 340. The stretchable member 350 is stretchable along the moving direction of the partitioning member 330. The first water passing port 311 may be located at a first end of the cylinder 340. The second water passing port 321 may be located at the second end of the cylinder 340. A first receptacle 310 is formed between the divider 330 and the first end. A retractable member 350 may be connected between the divider 330 and the second end.

Since the retractable member 350 is located at the side of the second receiving cavity 320, it occupies a certain space. In the case where the cylinder 340 is a cylinder, the cross-sectional area of the second cavity 320 is smaller than that of the first cavity 310. Through the arrangement, the water storage device 300 is simple in structure and low in production cost.

In one embodiment, the telescoping member 350 can be a telescoping tube. The interior of the bellows forms a second volume 320. The telescoping tubes may comprise a variety of structures such as bellows. In order to enhance the radial mechanical strength of the corrugated pipe and prevent radial deformation, the corrugated pipe can be sleeved with components such as a spring and the like. With this arrangement, it is easily achieved that the cross-sectional area of the second cavity 320 is smaller than that of the first cavity 310, the structure of the water storage device 300 is simpler, and the production cost is further reduced.

In another embodiment, the space between retractable member 350 and barrel 340 defines second receptacle 320. With this arrangement, it is convenient to arrange various types of sensors on the second receiving chamber 320 for automatic control. In this embodiment, the retractable member 350 may also be a retractable tube as described above, or a retractable tube with an additional spring. Of course, the retractable member 350 may be solid as long as the objects of the present invention can be achieved.

Preferably, as shown in fig. 1, the partition 330 may include a partition 331 and a sealing member 332. The sealing member 332 may be clamped between the outer periphery of the partition 331 and the inner wall of the cylinder 340. The seal 332 may include a gasket or the like. With this arrangement, the partition 330 has a simple structure and a superior sealing property, and prevents water cross-flow between the first and

second chambers

310 and 320.

Preferably, water purifier 100 may further include a controller (not shown). The controller may be electrically connected to the waterway switching device 200 and the return solenoid valve 140, respectively. The controller may control the waterway switching device 200 to turn on the second passage 220 and close the return solenoid valve 140 when receiving an electric signal for starting water intake. The controller may turn on the return solenoid valve 140 and control the water switching device 200 to turn on the second path 220 when receiving an electric signal to stop taking water.

The water intake apparatus 400 may include a faucet, a pipeline machine, and the like. Wherein the faucet may comprise a mechanical faucet; optionally, the faucet may also comprise an electrically controlled faucet. If the water intake device comprises a mechanical faucet, the water purifier can also comprise a check valve and a high-pressure switch. In the embodiment shown in fig. 1, the check valve may be replaced by a waterway switch device 200, and when water intake is stopped, the first passage 210 is closed, and water pressure may be established in the pipeline where the high pressure switch 410 is located. The electrical signals to start and stop water intake may be sent by the high voltage switch 410. Generally, when the high-voltage switch detects that the water pressure in a pipeline where the high-voltage switch is located reaches a set pressure, an electric signal for stopping water taking is sent; when the high-voltage switch detects that the water pressure in the pipeline where the high-voltage switch is located is lower than the set water pressure, an electric signal for starting water taking is sent. In another embodiment, a hall inductive switch may be disposed at the switch of the mechanical faucet, and the switch action of the mechanical faucet is converted into an electrical signal through the hall inductive switch.

The electric control faucet and the pipeline machine can be connected and disconnected with the water channel through the electric control valve, the electric control valve can be controlled through the electric control switch, and when the electric control valve is operated by the electric control switch, electric signals for starting water taking and stopping water taking are sent to the controller at the same time, so that the controller can perform subsequent action control on the water purifier.

The above water intake device and the principle of the electric signal sent by the water intake device to stop taking water are well known to those skilled in the art and will not be described in detail.

Through setting up the controller, can realize purifier 100's automatic control, user experience is better.

As mentioned above, when the power is turned on, the second path 220 is turned on and the first path 210 is turned off, so that the first section of water with higher TDS flows into the second cavity 320. When the first section of water in the reverse osmosis filter element 130 is drained, the first passage 210 can be controlled to be conducted. The following methods can be used to control the conduction of the first path 210:

in a preferred embodiment, water purifier 100 may further include a timer (not shown). The timer and controller may be integrated. The timer may be used to accumulate the power-on duration, i.e., time the on duration of the second channel 220. The controller may be electrically connected to the timer. When the startup duration is greater than or equal to the preset duration threshold, the controller controls the circuit switching device 200 to turn on the first channel 210. The duration threshold may be 60 seconds, 70 seconds, 80 seconds, etc. The time threshold may be set according to the performance of the water purifier 100. Generally speaking, the time that the higher first section water of TDS flows out is comparatively stable in the reverse osmosis filter core 130, consequently through setting up reasonable length of time threshold value of predetermineeing, can ensure that the higher first section water of TDS flows out in the reverse osmosis filter core 130 entirely. Subsequently, the first path 210 is controlled to be conductive. The second path 220 is closed, and the pure water continuously prepared by the reverse osmosis filter element 130 can be delivered to the water outlet end of the water purifier 100 through the first path 210. By setting the timer and the controller to compare the startup time with the preset time threshold, the first passage 210 can be switched on in time, and the obtained water is ensured to meet the standard while the user is ensured to take water uninterruptedly.

In another preferred embodiment, water purifier 100 may further comprise a first pressure sensor (not shown). The first pressure sensor may employ various types of pressure sensors known in the art or that may occur in the future. The controller may be electrically connected to the first pressure sensor. A first pressure sensor may be disposed between the outlet of the first passageway 210 and the outlet end of the water purifier 100. Preferably, as shown in fig. 1, the first pressure sensor may be a high-voltage switch 410. The first pressure sensor may be configured to detect a first water pressure. When the first water pressure is less than or equal to the first preset water pressure threshold, the controller controls the water passage switching device 200 to conduct the first passage 210. The first predetermined hydraulic pressure threshold may be 0.1 mpa, 0.2 mpa, or the like. The first preset water pressure threshold may be set according to the performance of the water purifier 100. Generally speaking, the higher first section of water of TDS is all flowed out's volume comparatively stable in the reverse osmosis filter core 130, and through reasonable setting, the pure water in first appearance chamber 310 can all flow out this moment, and the water pressure between the delivery port of first passageway 210 and the play water end of purifier 100 is lower. Consequently through setting up reasonable first preset water pressure threshold value, can ensure that the higher first section water of TDS is whole to be flowed out in the reverse osmosis filter core 130.
