BACKGROUND

In various locations around the world, the quality of tap water is poor due to the addition of chemicals or lack of water purification technology. When consumers drink tap water directly, harmful substances in tap water may enter the consumer's body. Therefore, water purification equipment is becoming more and more popular.


Some existing water purification equipment water purification equipment includes a water tank and a water supply component and is configured to be placed on a table or countertop. The water supply component provides power through a water pump to control the raw water in the water tank to flow through the filter element and be discharged from the outlet. The equipment commonly requires that the pump and the filter element be independently installed in the water purification equipment, which can result in a complicated flow path for the water and/or complicated assembly.


Moreover, when the water purification equipment and the water pump are turned on, the water in the water tank is pressurized from the inlet end through the water pump to the front end of the filter element. Due to the certain resistance of the filter element itself to the water flow, a certain water pressure will be generated between the water pump and the filter element, and the water flow will eventually flow out of the outlet through the filter element. When the water pump is turned off, there is still water pressure in the upstream pipeline because the water pressure between the water pump and the filter element cannot be released immediately. Under the action of water pressure, the water in the upstream pipeline flows to the outlet end, causing water to continuously drip from the outlet of the water purification equipment after shutdown, which may cause problems for some users.


In order to prevent dripping water, conventional water purification equipment may include a switch solenoid valve in the upper water pipeline which is closed at the same time as the water pump. However, back pressure on the solenoid valve may cause the solenoid valve to fail to an open configuration, causing the entire water pipeline to be pressurized and rendering the system unable to discharge water.


Accordingly, there remains a need for alternative water purification equipment.

Disclosed herein are water supply assemblies, filter elements, and water purification devices including the same. In various aspects, the water supply assembly comprises a water assembly housing, a water pump positioned within the water assembly housing and comprising a water pump inlet and a water pump outlet, a water inlet and a water outlet, and a filter element fluidly coupled to the water pump. The filter element is positioned within the water assembly housing along a water flow path between the water pump outlet and the water outlet and the water inlet is positioned along the water flow path upstream of the water pump inlet.


Water Supply Assemblies

In various aspects and as shown in FIGS. 1-8, a water supply assembly includes a water supply line 1, a water pump 152, a filter element 100, and a pressure relief pipeline 4. The water supply line 1 defines a water flow path that extends from a water inlet 156 to a water outlet 12 of the water supply line 1. The water inlet 156 is fluidly coupled to a water source (not shown). The water source can be, for example, a water tank containing raw (e.g., unfiltered) water. In such configurations, the water inlet 156 is configured to take water in from the water tank into the water supply line 1, such as through a suction pipe and filter head. Alternatively, the water source may be a pressure-free water supply pipeline. In such configurations, an outlet of the pressure-free water supply pipeline may be directly connected to the water inlet 156 to provide water through the water inlet 156 to the water supply line 1. In still other aspects, the water source may be a container or scene for raw (e.g., unfiltered) water in any space or area (such as outdoor rivers, lakes, ponds, streams, etc.), and the water inlet 156 sucks raw water into the water supply line 1 from an appropriate position.


The water outlet 12 is used to dispense filtered water from water supply line 1. The water outlet 12 is generally connected to or includes a water outlet nozzle. The water pump 152 and the filter element 100 are positioned along the water flow path defined by the water supply line 1, with the water pump 152 positioned between the filter element 100 and the water inlet 156 of the water supply line 1. That is, between the water inlet 156 and the water outlet 12, the water pump 152 and the filter element 100 are sequentially arranged. In aspects, other components may additionally be located along the water flow path, including, but not limited to, water sterilizing devices (described below). In various aspects described herein, the filter element 100 is located on the head of the water pump 152 and filters the water passing through it. The water pump 152 generates water power to move the water from the water inlet 156 of the water supply line 1, through the filter element 100, and to the water outlet 12.


The pressure relief pipeline 4 is also connected to the water supply line 1. In aspects, the pressure relief pipeline 4 is connected in parallel with the water supply line 1. The pressure relief pipeline 4 has a first configuration (e.g., a cut-off state) and a second configuration (e.g., a pressure relief state). The pressure relief pipeline 4 is configured to be changed between the first configuration and the second configuration through a valve, such as an electronically controlled valve 43 fluidly coupled to the pressure relief pipeline. In various aspects, the pressure relief pipeline 4 is in the first configuration when the water pump 152 is turned on so that the water in the water supply line 1 flows through the water outlet 12 to provide water output from the water supply component. In various aspects, the pressure relief pipeline 4 is in the second configuration when the water pump 152 is turned off to relieve the pressure in the water supply line 1 so that water does not drip from the water outlet 12 of the water supply line 1.


In various aspects of the disclosure, the electronically controlled valve 43 is controlled to close to put the pressure relief pipeline 4 in the off state, and the electronically controlled valve 43 is controlled to open to put the pressure relief pipeline 4 in the pressure relief state. The first end 41 of the pressure relief pipeline 4 is connected to the water supply line 1 between the water pump 152 and the filter element 100, and the second end of the pressure relief pipeline 4 is connected to the water supply line 1 between the water inlet 156 and the water pump 152 or the second end 42 of the pressure relief pipeline 4 communicates with a water source. In some aspects, the electronically controlled valve 43 is a solenoid valve. Alternatively, the electronically controlled valve 43 may be an electric valve, and any type of valve that can be powered on and off is within the scope of protection of the present application.


The first end 41 of the pressure relief pipeline 4 is connected to the water supply line 1 between the filter element 100 and the water outlet 12, and the second end of the pressure relief pipeline 4 is connected to the water supply line 1 between the water inlet 156 and the water pump 152 or the second end 42 of the pressure relief pipeline 4 communicates with the water source. The second end 42 of the pressure relief pipeline 4 communicates with the water source specifically includes the following three situations: taking the water source as the raw water contained in the water tank as an example, the second end 42 of the pressure relief pipeline 4 can be located above the water tank, or the second end 42 of the pressure relief pipeline can penetrate into the water tank, or the second end 42 of the pressure relief pipeline is connected to the water tank wall, and the water tank wall has a drainage hole, and the second end 42 of the pressure relief pipeline is connected to the drainage hole.


In aspects of the present disclosure, the water supply assembly also includes a one-way valve 5, which can enable a reduction in, or elimination of, dripping. The one-way valve 5 is provided on the water supply line 1 and is located between the filter element 100 and the water outlet 12. Since the one-way valve 5 itself has a certain conduction pressure, under normal working conditions, it can only be turned on when there is a certain pressure upstream of the one-way valve 5, that is, when the water pump 152 is closed, the pressure upstream of the one-way valve 5 is reduced to the conduction pressure of the one-way valve 5, and the water outlet 12 can stop the water output, and the remaining water in the water supply line 1 is discharged through the pressure relief pipeline 4, which can make the water outlet 12 stop the water output as soon as possible and avoid dripping.


In order to ensure the maximum effect of the one-way valve 5, the one-way valve 5 is positioned adjacent to the water outlet 12. When the device adjacent to the water outlet 12 is a filtering device, the one-way valve 5 may be located between the filtering device and the water outlet 12. When the device adjacent to the water outlet 12 is a sterilization device, the one-way valve 5 may be located between the sterilization device and the water outlet 12.


As shown in FIGS. 1 and 2, the filter element 100 is located downstream of the water pump 152, and the first end 41 of the pressure relief pipeline 4 is connected to the water supply line 1 between the water pump 152 and the filter element 100 to relieve the water pressure between the water pump 152 and the filter element 100 to avoid water dripping from the water outlet 12. By cooperating with the one-way valve 5 on the upstream water supply line 1 downstream of the pressure relief pipeline 4, the water outlet 12 can be stopped as soon as possible and dripping from the water outlet 12 can be avoided or reduced.


In aspects of the disclosure, the water supply line 1 includes a first upper water pipe section 13 located between the water inlet 156 and the water pump 152, a second upper water pipe section 14 located between the water pump 152 and the filter element 100, and a third upper water pipe section 15 located between the filter element 100 and the water outlet 12. The first end 41 of the pressure relief pipeline 4 is connected to the second upper water pipe section 14, and the second end 42 of the pressure relief pipeline 4 is connected to the first upper water pipe section 13.


Turning now to FIGS. 3 and 4, an alternative configuration for a water supply assembly is shown. Although similar to the water supply assembly depicted in FIGS. 1 and 2, in aspects, the filter element 100 is located downstream of the water pump 152, and the first end 41 of the pressure relief pipeline 4 is fluidly coupled to the water supply line 1 between the filter element 100 and the water outlet 12 to remove the water pressure between the filter element 100 and the water outlet 12. The water between the filter element 100 and the water outlet 12 can be removed from the pressure relief pipeline 4 to reduce or even prevent water from dripping from the water outlet 12. By cooperating with the one-way valve 5 on the water supply line 1 downstream of the pressure relief pipeline 4, the water outlet 12 can be stopped as soon as possible and dripping from the water outlet 12 can be reduced or eliminated.


In aspects of the disclosure, the water supply line 1 includes a first upper water pipe section 13 located between the water inlet 156 and the water pump 152, a second upper water pipe section 14 located between the water pump 152 and the filter element 100, and a third upper water pipe section 15 located between the filter element 100 and the water outlet 12. The first end 41 of the pressure relief pipeline 4 is connected to the third upper water pipe section 15, and the second end 42 of the pressure relief pipeline 4 is connected to the first upper water pipe section 13.


Turning now to FIGS. 5-8, in some aspects of the disclosure, the water supply line 1 is connected to the pressure relief pipeline 4 through an electronic control valve in the form of a three-way solenoid valve 7. Alternatively, the electric control valve may be a three-way electric valve, and it is contemplated that the electronic control valve can be any type of three-way valve that can achieve power control on and off.


The three-way solenoid valve 7 is configured to turn on the water supply line 1 and cut off the pressure relief pipeline 4 when the water pump 152 is turned on, and turn off the water supply line 1 and turn on the pressure relief pipeline 4 when the water pump 152 is closed. When the water pump 152 is turned on, the water supply line 1 is in the conductive state, and the pressure relief pipeline 4 is in the cut-off state. Therefore, the water in the water supply line 1 flows out through the water outlet 12 output water from the water supply line 1. The pressure relief pipeline 4 does not affect the water output. When the water pump 152 is closed, the water supply line 1 is in the cut-off state, and the pressure relief pipeline 4 is in the pressure relief state to relieve the pressure of the water supply line 1 through the pressure relief pipeline 4. When the water pump 152 is closed, the water supply line 1 is cut off, and the water supply line 1 releases pressure through the pressure relief pipeline 4 so that water does not drip from the water outlet 12 of the water supply line 1.


In various aspects, the three-way solenoid valve 7 is provided between the water pump 152 and the filter element 100, or the three-way solenoid valve 7 is provided between the filter element 100 and the water outlet 12. The three-way solenoid valve 7 is connected to the first end 41 of the pressure relief pipeline 4, and the second end 42 of the pressure relief pipeline 4 is connected between the water inlet 156 and the water pump 152, or the second end 42 of the pressure relief pipeline 4 communicates with a water source.


As shown in FIGS. 5 and 6, the filter element 100 is located downstream of the water pump 152, and the three-way solenoid valve 7 is connected to the water supply line 1 between the water pump 152 and the filter element 100. That is, the three-way solenoid valve 7 is connected to the second upper water pipe section 14. In FIGS. 7 and 8, the filter element 100 is located downstream of the water pump 152, and the three-way solenoid valve 7 is connected to the water supply line 1 between the filter element 100 and the water outlet 12. That is, the three-way solenoid valve 7 is connected to the third upper water pipe section 15.


By using the three-way solenoid valve 7, on the one hand, the water supply line 1 can be cut off to avoid dripping water, and on the other hand, the pressure relief pipeline 4 can be turned on while the water supply line 1 is cut off, to prevent the back pressure of the three-way solenoid valve 7 from becoming too large to turn on the water supply line 1, and to avoid water stagnation and inability to discharge water in the water pipeline. In some other aspects of the disclosure, the three-way solenoid valve 7 is connected to the second end 42 of the pressure relief pipeline 4.



FIG. 34 illustrates yet another configuration of a water supply assembly in accordance with various aspects of the present disclosure. Similar to the other water supply assemblies shown and described herein, the water supply assembly in FIG. 34 includes a water pump 152, a water outlet 12, a water inlet 156, and a filter element 100. The water inlet 156 is connected to the suction pipe 1561. The water pump 152 is connected to the water pump inlet 1521 and the water pump outlet 1522. In FIG. 34, the water inlet of the filter element 100 is connected to the water inlet 156, the water outlet of the filter element 100 is connected to the water pump inlet 1521, and the water pump outlet 1522 is connected to the water outlet 12. The water inlet 156 and water outlet 12 are both located on the upper part of the water supply assembly, which may provide sufficient container placement space for receiving purified water and make connection of water pipes easier. It is contemplated that the water inlet and water outlet may be configured in other ways. For example, the water outlet may be positioned on the upper part of the water supply assembly for the user to receive water while the water inlet is positioned at the bottom of the water source and a water pipe is laid at the bottom of the water source to connect with the water pump module. This setting method of the inlet and water outlet nozzles can ensure the full utilization of water (especially when the water is set in a fixed container), and the water pipe is not exposed, with a simple appearance.


In some aspects, the water supply assembly includes a sterilization device 6. The sterilization device 6 sterilizes the water in the water supply line 1 to ensure the cleanliness and hygiene of the water outlet 12. The sterilization device 6 may be an ultraviolet sterilization device to kill bacteria and viruses in the water tank and avoid the growth of green algae. In FIG. 9, the sterilization device 6 is located on the water supply line 1 between the water outlet 12 and the filter element 100. However, the sterilization device 6 can also be located at other positions along the water supply line 1. For example, in FIG. 12, a sterilization device 6 may also be provided on the water tank cover 116 of the water tank. As another example, in FIG. 13, the sterilization device 6 is provided in the installation space between the water assembly housing 151 and the water assembly cover 155. In the configuration shown in FIG. 13, part of the water supply line 1 proximate the sterilization device 6 is transparent to enable the sterilization device 6 to kills bacteria and viruses in the water flowing through the water supply line 1.


Similarly, the sterilization device 6 may be located on the circuit board opposite to part of the water supply line 1. Again, the water supply line proximate the sterilization device 6 is a transparent part 16, thereby enabling the light of the sterilization device 6 to pass through the transparent part 16 to sterilize the water in the water supply line 1. Alternatively or additionally, antibacterial materials can also be added to the injection molded parts of the water tank, or antibacterial materials can be added to the filter element filter material to achieve the antibacterial effect.


In yet another example, the sterilization device 6 may be an overflow UV sterilization structure that is positioned directly on the water pump outlet 1522. Accordingly, UV sterilization can be carried out as water flows to the water outlet 12 after being filtered by the filter element 100 to remove microbial pollutants such as bacteria (Escherichia coli and Streptococcus glucose) and viruses in the water, and the sterilization rate can reach 99.9%.


Alternatively, a sterilization device 6 can be installed in the water tank 114 of the water purifier. The sterilization device 6 can include a rechargeable UV sterilization lamp, a polymer battery, and a power supply board. The sterilization device may be charged through a Type-C data cable or another suitable charging method. The sterilization device fixed between setting ribs on the water tank 114 or the cover of the water tank, although other methods for positioning the sterilization device are contemplated and possible. The sterilization device can be directly removed for charging and reinstalled for use after charging is completed.


In any of the aspects described herein, the sterilization device can be adjusted. For example, the angle of the UV sterilization lamp of the static sterilization device can be adjusted, and different powers, lamp beads, and irradiation angles can be configured according to the shape and capacity of the water tank. In some aspects, the working time of the UV sterilization lamp can be set through the control panel to effectively kill bacteria and viruses in the water and prevent the growth of green algae.


Water Purifiers

In various aspects of the disclosure, any of the water supply assemblies described hereinabove can be incorporated into a water purifier such as, for example, any of the water purifiers described hereinbelow. The water purifiers may be in the form of a counter-top purification system, a portable pitcher or kettle, a water purification bottle, or the like.


As shown in FIGS. 14 and 15, a water purifier includes a water tank 114 and a water supply assembly 115. The water tank 114 is used to accommodate raw water, and the water supply assembly 115 is used to purify the raw water in the water tank 114. The purified water flows out of the water outlet 12. The water supply assembly 115 is at least partially located in the water tank 114. In particular, the water tank 114 includes an installation part, which is detachably coupled to the water supply assembly, and an accommodating part, which is configured to hold the raw water. The installation and accommodation parts of the water tank 114 may be defined within the water tank 114 through a partition plate, or the accommodation part can be the internal cavity of the water tank, and the installation part can be an installation cavity of the upper water component formed outside of the water tank 114 through the enclosure plate. In other aspects, the installation part can be the installation structure on the water tank, and the water supply assembly and the water tank can be coupled through plug-in fit, hook connection, snap fit, etc. As shown in FIGS. 14 and 15, the water purifier also includes a water tank cover 116, which covers the upper opening of the water tank 114 and at least partially covers the top of the water supply assembly 115.


The water purifier is provided with a handle 141, and a special-shaped hole (not shown) for receiving the handle is provided on the side wall of the water tank 114. The special-shaped hole receives the handle 141 to couple the handle 141 to the water purifier and limit the rotation of the handle 141.


One or more seals may be included to create a water-tight interface between adjacent components. As shown in FIG. 10, the water pump 152, the filter element 100, and the sterilization device 6 are all located in a water assembly housing 151, and a water assembly cover 155 is used to close the top of the water assembly housing 151. In aspects, a first sealing element 83 is provided between the water assembly cover 155 and the water assembly housing 151 to provide a seal. In some aspects, part of the first upper water pipe section 13 of the water supply line 1 extends from the water assembly housing 151, and the part where the first upper water pipe section 13 of the water supply line 1 is assembled with the water assembly housing 151 is sealed by the second sealing element 84.
