[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] It should be noted that, in actual applications, those skilled in the art may configure the drink purifier device as a desktop drink purifier, or, may configure the drink purifier device as an all-in-one drink purifier, or, may configure the drink purifier device as any other possible form, etc. Such adjustments and changes to the specific setting types of the drink purifier device do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0033] The following takes a desktop water purifier as an example to introduce in detail a specific embodiment of the water purifier device of the present utility model.

[0034] Based on the existing drinking water purification equipment mentioned in the background technology, generally all of them have a single water supply mode, which cannot meet the needs of users in actual use and leads to poor user experience. Therefore, the utility model provides a drinking water purification equipment, which has a multi-water source water supply mode, and can switch between different water supply modes according to the user's usage needs, thereby greatly improving the user's experience.

[0035] Specifically, see Figures 1 to 3 , Figure 1 It is a schematic diagram of the structure of the drinking water purifier of the utility model in the first water supply mode, wherein it shows a water flow diagram when the first control valve is opened; Figure 2 It is a schematic diagram of the structure of the drinking water purifier of the utility model in the first water supply mode, wherein it shows a water flow diagram when the first control valve is closed; Figure 3 It is a schematic structural diagram of the drinking water purification device of the utility model in the second water supply mode.

[0036] like Figures 1 to 3 As shown, the drinking water purification device of the present invention has a water inlet 81 and a waste water outlet 82, and includes a water storage component 1, a water inlet pipe 2, a filter assembly and a waste water pipe 41, and the water storage component 1 has a water storage chamber 11 and a waste water chamber 12, wherein the drinking water purification device has a first water supply mode and a second water supply mode.

[0037] When the drinking water purification device is in the first water supply mode, the water inlet 81 is connected to the water inlet end of the filter assembly through the water inlet pipe 2, and the wastewater end of the filter assembly is connected to the wastewater port 82 through the wastewater pipe 41. When the drinking water purification device is in the second water supply mode, the water storage chamber 11 is connected to the water inlet end of the filter assembly, and the wastewater end of the filter assembly is connected to the wastewater chamber 12.

[0038] A flow detection component 411 is provided on the water inlet pipe 2 and / or the waste water pipe 41. The drinking water purification device also includes a first control valve 21 and a second control valve 421. The first control valve 21 is used to control the on-off of the water inlet pipe 2. The second control valve 421 can selectively connect the waste water end of the filter assembly with the waste water chamber 12. The flow detection component 411 is communicatively connected with the first control valve 21 and the second control valve 421 so that the drinking water purification device can switch between the first water supply mode and the second water supply mode.

[0039] By configuring the drinking water purification device to have a first water supply mode and a second water supply mode, the drinking water purification device can have multiple water supply modes, thereby meeting the user's usage requirements in different usage environments and improving the user's usage experience. By configuring the flow detection component 411, it is possible to conveniently judge the user's water supply mode during actual use (installation) based on the detection result of the flow detection component 411, thereby facilitating automatic switching of the drinking water purification device to a corresponding water supply mode, thereby facilitating automatic identification and automatic switching of the water supply mode of the drinking water purification device and further improving the user's usage experience.

[0040] It should be noted that if the user adopts the first water supply mode (i.e., tap water supply) when installing the drinking water purification device, the water inlet 81 and the wastewater outlet 82 are both in a connected state, one end of the water inlet pipe 2 is connected to the water source, the other end of the water inlet pipe 2 is connected to the water inlet end of the filter assembly, one end of the wastewater pipe 41 is connected to the wastewater end of the filter assembly, and the other end of the wastewater pipe 41 is connected to the wastewater outlet 82 of the drinking water purification device. At this time, if the device operates normally, after the first control valve 21 is started, a preset flow of water flows through the water inlet pipe 2 and / or the wastewater pipe 41. At this time, the flow detection component 411 will be able to detect the water flow signal, and the second control valve 421 will be switched to prevent the wastewater end of the filter assembly from being connected to the wastewater chamber 12. When making water, tap water flows from the water inlet 81 through the water inlet pipe 2 into the water inlet end of the filter assembly, the filter assembly filters the water, and the wastewater generated by the filter assembly is discharged to the wastewater outlet 82 through the wastewater pipe 41.

[0041] If the user adopts the second water supply mode when installing the drinking water purification equipment, the water inlet 81 and the waste water outlet 82 will be blocked. At this time, if the equipment operates normally, after the first control valve 21 is started, the water flow of the preset flow rate cannot be detected in the water inlet pipe 2 and the waste water pipe 41. At this time, the flow detection component 411 will not detect the water flow signal, so the first control valve 21 will be closed, and the second control valve 421 will be switched to connect the waste water end of the filter component with the waste water chamber 12. When making water, the water in the water storage chamber 11 is transported to the water inlet end of the filter component, the filter component filters the water, and the waste water generated by the filter component enters the waste water chamber 12.

[0042] Therefore, the drinking water purification device can determine the water supply mode of the drinking water purification device during installation according to the detection data of the flow detection component 411, and switch the drinking water purification device between the first water supply mode and the second water supply mode through the first control valve and the second control valve.

[0043] In a specific embodiment, the flow detection component 411 is disposed on the water inlet pipe 2 .

[0044] In another specific embodiment, the flow detection component 411 is disposed on the waste water pipe 41 .

[0045] In another possible embodiment, the flow detection component 411 is disposed on both the water inlet pipe 2 and the waste water pipe 41 .

[0046] Preferably, the flow detection member 411 is disposed on the waste water pipe 41 .

[0047] Through such a setting, compared with the form of setting the flow detection component 411 on the water inlet pipe 2, setting the flow detection component 411 on the waste water pipe 41 can avoid the water in the water storage chamber 11 interfering with the detection of the flow detection component 411, thereby improving the accuracy of judging the water supply mode.

[0048] It should be noted that a person skilled in the art may configure the water inlet pipe 2 and the water storage chamber 11 to be respectively connected to the water inlet end of the filter assembly, or the water inlet pipe 2 may be configured to be connected to the water storage chamber 11, the water inlet pipe 2 and the water storage chamber 11 may be jointly connected to the water inlet end of the filter assembly, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0049] Preferably, if Figures 1 to 3 As shown, the drinking water purification device also includes a first water pump 5, which is used to transport water in the water inlet pipe 2 and / or the water storage chamber 11 to the filter assembly. The water inlet pipe 2 is also connected to the water storage chamber 11, and the flow detection component 411 is arranged on the waste water pipe 41.

[0050] By setting the water inlet pipe 2 to be connected to the water storage chamber 11, when the drinking water purification device is in the first water supply mode, part of the water flowing out of the water inlet pipe 2 is transported to the water inlet end of the filter component through the first water pump 5, and the other part of the water flowing out of the water inlet pipe 2 enters the water storage chamber 11 for storage. When the water in the water storage chamber 11 reaches a preset water level, water is supplied through the water storage chamber 11, so that zero-pressure water supply can be achieved in the tap water supply mode (the water inlet end of the first water pump 5 is close to zero pressure), so that the first water pump 5 can be applied to both the first water supply mode and the second water supply mode, and different demands on the first water pump 5 due to different water pressures in the first water supply mode and the second water supply mode can be avoided, thereby solving the problem that different water pumps need to be adapted for tap water supply and water tank water supply, and further improving the user experience.

[0051] It should be noted that, in actual applications, those skilled in the art may configure the water storage component 1 in the form of a water tank, or, may configure the water storage component 1 in the form of a storage tank, or, may configure the water storage component 1 in any other possible form, etc. Such adjustments and changes to the specific setting type of the water storage component 1 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0052] Preferably, the water storage member 1 is a water tank.

[0053] It should be noted that, in actual applications, those skilled in the art may configure the water storage component 1 to include a water tank and a wastewater tank, wherein the water tank has a water storage chamber 11 and the wastewater tank has a wastewater chamber 12, or the water storage component 1 may be configured only as a water tank, wherein the water tank has a water storage chamber 11 and a wastewater chamber 12, and so on. Such adjustments and changes to the specific setting type of the water storage component 1 do not deviate from the principle and scope of the present utility model and should be included in the protection scope of the present utility model.

[0054] Preferably, if Figures 1 to 3 As shown, the water storage component 1 is a water storage tank, which has a water storage chamber 11 and a waste water chamber 12.

[0055] Preferably, if Figures 1 to 3 As shown, a first water level detection component 111 is also provided in the water storage chamber 11 of the utility model. The first water level detection component 111 is used to detect the water level in the water storage chamber 11. The first water level detection component 111 is communicatively connected with the first control valve 21 so as to start or close the first control valve 21 according to the water level in the water storage chamber 11.

[0056] By arranging a first water level detection component 111 in the water storage chamber 11, and the first water level detection component 111 is communicatively connected with the first control valve 21, on the one hand, when the first water level detection component 111 detects that the water level in the water storage chamber 11 reaches a first water level, the first control valve 21 can be closed to avoid overflowing. On the other hand, when the first water level detection component 111 detects that the water level in the water storage chamber 11 is lower than a second water level (the second water level is lower than the first water level), the first control valve 21 can be started, thereby timely replenishing water into the water storage chamber 11 through the water inlet pipe 2, which helps to realize automatic water supply and further enhance the user experience.

[0057] It should be noted that, in actual applications, the first water level detection component 111 can be set as a liquid level probe, or the first water level detection component 111 can be set as a liquid level sensor, or the first water level detection component 111 can be set as a float level gauge, etc. Such adjustments and changes to the specific setting type of the first water level detection component 111 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0058] Exemplarily, the first water level detecting member 111 is a float level gauge.

[0059] It should be noted that, in actual applications, the water inlet pipe 2 can be arranged to be connected to the water storage chamber 11 through the first water supply pipe, and the water storage chamber 11 can be arranged to be connected to the water inlet end of the first water pump 5 through the second water supply pipe. Alternatively, the connection between the water inlet pipe 2, the water storage chamber 11 and the first water pump 5 can be achieved by setting a tee. Specifically, the first branch of the tee is connected to the water inlet pipe 2, the second branch of the tee is connected to the water storage chamber 11, the third branch of the tee is connected to the water inlet end of the first water pump 5, and so on. Such adjustments and changes to the specific connection methods between the water inlet pipe 2 and the water storage chamber 11 and the first water pump 5 do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0060] Preferably, if Figures 1 to 3 As shown, the drinking water purification device of the present invention also includes a three-way pipe, a first branch of the three-way pipe is connected to the water inlet pipe 2, a second branch of the three-way pipe is connected to the water storage chamber 11, and a third branch of the three-way pipe is connected to the water inlet end of the first water pump 5.

[0061] It should be noted that the present invention does not impose any particular limitation on the specific configuration type of the second control valve 421 , as long as the wastewater end of the filter assembly can be selectively connected to the wastewater chamber 12 .

[0062] In a specific embodiment, Figures 1 to 3 As shown, the drinking water purification device also includes a wastewater pipe 42, the wastewater end of the filter assembly is connected to the wastewater chamber 12 through the wastewater pipe 42, and the second control valve 421 is arranged on the wastewater pipe 42 and is used to control the on and off of the wastewater pipe 42.

[0063] When the second control valve 421 is in a closed state, the wastewater end of the filter assembly is not connected to the wastewater delivery pipe 42, and the wastewater end of the filter assembly is connected to the wastewater pipe 41;

[0064] When the second control valve 421 is in an open state, the wastewater end of the filter assembly is in communication with the wastewater delivery pipe 42 .

[0065] In another specific embodiment, the drinking water purification device also includes a wastewater water pipe 42, and the wastewater end of the filter component is connected to the wastewater chamber 12 through the wastewater water pipe 42. The second control valve 421 is a one-inlet and two-outlet solenoid valve (not shown in the figure), and the first end of the one-inlet and two-outlet solenoid valve is connected to the wastewater end of the filter component, and the second end and the third end of the one-inlet and two-outlet solenoid valve are connected to the wastewater pipe 41 and the wastewater water pipe 42 respectively.

[0066] When the one-inlet-two-outlet solenoid valve is switched to connect the first end with the second end, the wastewater end of the filter assembly is connected with the wastewater pipe 41, and the wastewater end of the filter assembly is not connected with the wastewater delivery pipe 42;

[0067] When the one-inlet-two-outlet solenoid valve is switched to connect the first end with the third end, the wastewater end of the filter assembly is connected with the wastewater delivery pipe 42 .

[0068] Compared with setting the second control valve 421 as a one-inlet and two-outlet solenoid valve, setting the second control valve 421 as a solenoid valve arranged on the wastewater conveying pipe 42 can reduce the cost of the second control valve 421, thereby reducing the cost of the drinking water purification equipment and further improving the user experience.

[0069] It should be noted that the present invention does not impose any special limitation on the specific setting type of the flow detection component 411. For example, the flow detection component 411 can be set as a flow switch, or the flow detection component 411 can be set as a flow meter, or the flow detection component 411 can be set in any other possible form, etc. Such adjustments and changes to the specific setting type of the flow detection component 411 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0072] By setting up the reflux pipe 6, when the drinking water purification device is not used for a long time, the water at the water outlet end of the filter component can be returned to the water inlet end of the filter component through the reflux pipe 6, thereby preventing water with poor water quality from flowing into the pure water tank 71, solving the problem of "the first cup of water has a high TDS value", improving the water quality of the water outlet of the drinking water purification device, and further improving the user experience.

[0073] Preferably, a one-way valve 62 is also provided on the reflux pipe 6 to prevent water at the water inlet end of the filter assembly from flowing to the water outlet end of the filter assembly through the reflux valve 61, thereby avoiding water mixing.

[0074] Preferably, the drinking water purification device of the present invention further comprises a water outlet assembly, the water outlet end of the filter assembly is connected to the water outlet assembly, and the water outlet assembly is used to store and / or output water filtered by the filter assembly.

[0075] By providing a water outlet component, the water filtered by the filter component can be stored or output, thereby making it convenient for users to obtain pure water.

[0076] In a specific embodiment, the water outlet assembly only includes a pure water outlet component (not shown in the figure), and the pure water outlet component is directly connected to the water outlet end of the filter assembly to output the water filtered by the filter assembly.

[0078] It should be noted that the pure water outlet pipe is not limited to being set as a pure water outlet pipe to transport water filtered by the filter assembly to the pure water outlet. For example, the pure water outlet component can be set as a pure water outlet pipe and a water outlet nozzle, one end of the pure water outlet pipe is connected to the water outlet end of the filter assembly, and the other end of the pure water outlet pipe is connected to the water outlet nozzle. Alternatively, the pure water outlet component can be set as a pure water outlet pipe and a faucet, one end of the pure water outlet pipe is connected to the water outlet end of the filter assembly, and the other end of the pure water outlet pipe is connected to the faucet, and so on. Such adjustments and changes to the specific setting types of the pure water outlet components do not deviate from the principle and scope of the present utility model, and should be included in the protection scope of the present utility model.

[0079] In another specific embodiment, the water outlet assembly only includes a pure water tank, which is connected to the water outlet end of the filter assembly so that the water filtered by the filter assembly is stored in the pure water tank.

The water outlet end of the filter assembly is connected to the pure water tank 71 , and the second water pump 72 is used to transport the water in the pure water tank 71 to the water outlet component 74 .

[0081] It should be noted that, compared with setting the water outlet component only in the form of a pure water tank 71 or a water outlet component 74, setting the water outlet component in the form of a pure water tank 71, a second water pump 72 and a water outlet component 74 can not only store the filtered water in the pure water tank 71, but also when the user needs to get water, the water in the pure water tank 71 can be transported to the water outlet component 74 through the second water pump 72, which not only makes it convenient for the user to get water, but also increases the water outlet flow rate, reduces the user's waiting time, and further enhances the user's experience.

[0084] It should be noted that the present invention does not impose any special restrictions on the specific setting type of the second water level detection member 712, as long as it can detect the water level in the pure water tank 71. For example, the second water level detection member 712 can be set as a liquid level probe, or the second water level detection member 712 can be set as a liquid level sensor, or the second water level detection member 712 can be set as a float level gauge, etc. Such adjustments and changes to the specific setting type of the second water level detection member 712 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0091] In one possible embodiment, Figures 1 to 3 As shown, a TDS detection sensor 7512 is also provided on the first water outlet pipe 751. The TDS detection sensor 7512 is used to detect the TDS value of the water flowing out from the water outlet end of the filter component. In this way, when the data detected by the TDS detection sensor 7512 exceeds the preset value, a prompt is issued to the user to prompt the user to replace the filter element.

[0092] Preferably, if Figures 1 to 3 As shown, the drinking water purification device of the present invention further includes a heating component 73 , which is disposed between the pure water tank 71 and the water outlet component 74 and is used to heat the water flowing out of the pure water tank 71 .

[0100] Through such a setting, impurities and sediment in the water can be removed through the pre-filtration unit, and then bacteria, viruses, heavy metals, organic matter and other impurities in the water can be removed through the reverse osmosis membrane filter element. Finally, the taste is improved through the post-filtration filter element 32, thereby improving the water quality of the purified water of the drinking water purification equipment and further enhancing the user experience.

[0101] Preferably, the filtration assembly further includes a wastewater valve 33 , the water inlet of the wastewater valve 33 is connected to the wastewater end of the reverse osmosis membrane filtration unit, and the water outlet of the wastewater valve 33 is connected to the wastewater pipe 41 and / or the wastewater water pipe 42 .

[0104] Through such an arrangement, the number of wastewater valves 33 can be reduced, further saving the production cost of the drinking water purification equipment.

[0105] It should be noted that, in actual applications, those skilled in the art may configure the filter assembly to include a pre-filter element, a reverse osmosis filter element and a post-filter element 32, or, may configure the filter assembly to include a composite filter element 31 and a post-filter element 32, wherein the composite filter element 31 includes a PPC filter unit and a reverse osmosis membrane filter unit, or, may configure the filter assembly to be an integrated filter element, wherein the integrated filter element includes a pre-filter unit, a reverse osmosis membrane filter unit and a post-filter unit connected in sequence, and so on.
