Well-known methods, procedures, and components have not been described in detail so as not to obscure the present invention.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the present invention, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

As shown in FIG. 1, the utility model provides a water purification drinking machine, it includes the control unit, water purification system and drinking water system, and the raw water can purify through water purification system, and the water purification after the purification gets into drinking water system, and user's accessible drinking water system water intaking is drunk.

Wherein, preferably, water purification system includes former water tank 1, drive arrangement and the filter element group spare that connects gradually. The raw water tank 1 is used for storing raw water, and is provided with a water inlet pipe connector 2 and a water replenishing port (not shown in the figure), and the water inlet pipe connector 2 can be used for being connected with a raw water source (such as a tap). For the convenience of water supply of users, the water supply port is preferably arranged at the top of the raw water tank 1. The user can select whether to carry out raw water supply in the raw water tank 1 through the mode of supplying water to the raw water tank 1 through the tap or automatically pouring water from the water supply opening according to the specific application scene. For example, in a situation where there is no water tap or when the water tap is cut off, the user can pour water into the raw water tank 1 through the refill port, and in a situation where there is a water tap, the user can connect the water tap to the water inlet pipe connection 2 and supply water into the raw water tank 1 through the water tap.

Further, in order to automatically control the water supply to the raw water tank 1, it is preferable to provide a liquid level detection device, a liquid level switch, and other elements in the raw water tank 1, so as to automatically supply and stop the water supply to the raw water tank 1. The automatic water supply and the water supply stopping can be realized in various ways, for example, as shown in fig. 1, a mechanical floating ball liquid level switch 3 is arranged at the water inlet pipe interface 2, when the liquid level in the raw water tank 1 reaches the position of the floating ball liquid level switch 3, the floating ball liquid level switch 3 closes the water inlet pipe interface 2, the water supply is stopped, and the water in the raw water tank 1 is prevented from overflowing. For another example, an electronic liquid level switch is disposed at the highest liquid level in the raw water tank 1, a switch valve (e.g., an electromagnetic valve) is disposed at the water inlet pipe interface 2, and when the electronic liquid level switch detects that water is present, it indicates that the raw water in the raw water tank 1 has reached the highest liquid level, and the switch valve is controlled to close the water inlet pipe interface 2. For another example, a liquid level meter is disposed in the raw water tank 1, a switch valve (e.g., an electromagnetic valve) is disposed at the inlet pipe interface 2, and when the liquid level meter detects that the water in the raw water tank 1 reaches a set maximum liquid level, the switch valve is controlled to close the inlet pipe interface 2.

In addition, the reminding that the liquid level is too low can be realized through elements such as a liquid level detection device, a liquid level switch and the like arranged in the original water tank 1, so that the idle running of a driving device is avoided, and a user is reminded in time of adding water into the original water tank. For example, in the embodiment shown in fig. 1, a first liquid level detection element 4 is arranged at the bottom of the raw water tank 1, when the first liquid level detection element 4 detects that the water level in the raw water tank 1 reaches the lowest water level, the driving device is controlled to stop operating or not allowed to operate, and an alarm can be given through a corresponding water shortage alarm device, for example, a light, a character, a sound and the like.

The driving device is used for driving water to flow from the raw water tank 1 to the direction of the filter element component. Because raw water storage is in raw water tank 1 for the pressure of raw water is very little, uses ordinary booster pump to be difficult to reach the required pressure demand of filter element group spare, consequently, drive arrangement preferably adopts self priming water pump 5.

The filter element assembly comprises at least one filter element, and the adopted filter elements can be specifically set according to the quality of raw water, the requirement on the purity of pure water and the like. For example, in the embodiment shown in fig. 1, the cartridge assembly comprises a first cartridge 6, a second cartridge 7, and a third cartridge 8 disposed in sequence along a water path, wherein the first cartridge 6 is preferably a PP cotton cartridge, the second cartridge 7 is preferably a granular activated carbon cartridge, and the third cartridge 8 is preferably a reverse osmosis membrane cartridge. The reverse osmosis membrane cartridge has a pure water outlet 81 and a concentrated water outlet 82. The pure water obtained by filtering the reverse osmosis membrane filter element can flow out through a pure water outlet 81 and enter a drinking water system. Of course, it is understood that the reverse osmosis membrane filter element can be replaced by other filter elements with the same filtering effect. The pure water outlet 81 of the reverse osmosis membrane filter element is provided with a one-way valve 9, and the one-way valve 9 only allows water to flow towards the drinking water system, so that the normal operation of the water purification system is prevented from being influenced by water backflow.

A water storage device interface 10 is arranged between the pure water outlet 81 and the water inlet of the drinking water system, and when the water demand cannot meet the requirement, the water storage device can be connected into the water purifying drinking machine through the interface, so that the pure water storage capacity of the water purifying drinking machine is increased, and the water demand of more people is met.

Specifically, when the water storage device is not connected to the water purifying dispenser, the pure water filtered by the water purifying system enters the drinking water system, and when the water storage device is connected to the water purifying dispenser, a part of the pure water filtered by the water purifying system enters the pressure barrel 11 for storage, and the other part of the pure water enters the drinking water system. The user can select whether to connect the water storage device according to the demand of the water purification amount, thereby expanding the application range and application scene of the water purification dispenser, for example, the water storage device can meet the water demand without being connected when the water purification dispenser is used at home, and the water storage device needs to be connected when the water purification dispenser is used in public places. In addition, the water purifying and drinking machine provided by the application has lower requirements on a driving device in a water purifying system, has lower requirements on the water purifying capacity of the reverse osmosis membrane filter element, reduces the production cost, and achieves the effect that the small water purifying capacity meets the use requirements of more people.

Further preferably, the water storage device comprises a pressure barrel 11, the pure water outlet is connected with two branches, one branch is connected with the drinking water system, the other branch is a branch pipeline, the tail end of the branch pipeline forms a water storage device interface 10, a high-pressure switch 12 is further arranged on the branch pipeline, when the pressure in the pressure barrel 11 is too large, the high-pressure switch 12 is disconnected, the water purification system stops running, and the running stability of the system is guaranteed.

In order to facilitate the installation of the pressure barrel 11, a quick connector is arranged at the water storage device interface 10, and the quick connection between the pressure barrel 11 and the water storage device interface 10 is realized through the quick connector, so that the pressure barrel is convenient to use. The pressure barrel 11 can be arranged outside the water purifying dispenser or inside the water purifying dispenser, and the installation position of the pressure barrel 11 can be preset inside the water purifying dispenser for ensuring the appearance.

In one embodiment, since the pressure at the high-pressure switch 12 is still changed when the water purifier is not connected to the pressure barrel 11, the water purifier may only have a control program built therein, which is set according to the control logic when the water purifier is connected to the pressure barrel 11, that is, the water purifier is controlled to stop producing water when the pressure value at the high-pressure switch 12 reaches a predetermined value, and the water purifier is controlled to start producing water when the pressure value at the high-pressure switch 12 is reduced to a certain value.

In an alternative embodiment, the water purifier has two operation modes, namely a first operation mode not connected to the pressure barrel 11 and a second operation mode connected to the pressure barrel 11, that is, the water purifier has two control programs, one control program is set according to the control logic when the pressure barrel 11 is not connected (for example, water production is stopped when the water level in the purified water tank reaches the highest water level), and the other control program is set according to the control logic when the pressure barrel 11 is connected. The water purifier can be switched between two operation modes.

For example, a detection device for detecting whether the pressure barrel 11 is installed in the water purifying dispenser is arranged in the water purifying dispenser, when the detection device does not detect that the pressure barrel 11 is installed in the water purifying dispenser, the water purifying dispenser operates in a first operation mode, and when the detection device detects that the pressure barrel 11 is installed in the water purifying dispenser, the water purifying dispenser automatically switches to a second operation mode. The specific structural form of the detection device is not limited, for example, the detection device is an elastic sheet arranged at the water storage device interface 10 and a pressure sensing device used for detecting the stress of the elastic sheet, when the pressure barrel 11 is not installed, the elastic sheet is in a free state, the water purifier operates in a first operation mode, when the pressure barrel 11 is installed, the pressure barrel 11 can stretch into the water storage device interface 10 and push the elastic sheet to deform, the pressure sensing device senses the change of pressure, so that the pressure barrel 11 is judged to be connected, and the water purifier automatically switches to a second operation mode.

Of course, the clean drinking machine mode can also be manually switched. For example, an operation mode selection key is provided in the water purifier, and the water purifier operation mode is set by operating the operation mode selection key.

The water storage device interface 10 may be one, or may be a plurality of interfaces with different sizes, so as to match different pressure tanks 11, so as to change the pure water capacity of the water purification system.

Further preferably, a post-treatment filter element 13 may be further disposed between the water storage device interface 10 and the water inlet of the drinking water system, the pure water filtered by the water purification system and the pure water stored in the pressure tank 11 need to be filtered by the post-treatment filter element 13 and then enter the drinking water system, so as to further improve the water quality of the pure water, and the post-treatment filter element 13 may be, for example, an ultrafiltration membrane filter element or a composite filter element of an ultrafiltration membrane and a carbon rod.

Further preferably, the concentrate outlet 82 of the reverse osmosis membrane cartridge is connected to the drain pipe 15 and the concentrate tank 16 via the waste water ratio solenoid valve 14 and a switching device for switching communication of the concentrate outlet 82 between the drain pipe 15 and the concentrate tank 16. The user can specifically select whether the concentrate is discharged through the drain pipe 15 or into the concentrate tank 16 according to the application scenario of the water purifier. For example, when there is a drainage channel in the application scene, the drainage pipe 15 can be selected to directly drain the concentrated water, and when there is no drainage channel or the drainage channel is blocked or the concentrated water needs to be collected for use in the application scene, the concentrated water can be selected to be drained into the concentrated water tank 16. The switching device may be, for example, a mechanical reversing valve 17 as shown in fig. 1, and a user may manually operate the mechanical reversing valve 17 to switch the concentrated water discharge mode, or may realize the switching of the concentrated water discharge mode through the cooperation of a rocker switch and an electromagnetic valve.

Further preferably, a second liquid level detection element 18 is further disposed in the concentrated water tank 16, and when the second liquid level detection element 18 detects that the liquid level in the concentrated water tank 16 reaches the maximum liquid level, the water purification system is controlled to stop running, so as to avoid overflow of concentrated water from the concentrated water tank 16, which causes inconvenience for use.
