DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Please refer to Figures 1 to 3 The present application provides a water purification system, including a water purifier 110 and a faucet 120, wherein the water outlet of the water purifier 110, the water inlet of the faucet 120 and the water inlet of the water purifier 110 are connected to each other, a heating mechanism 140 is arranged between the water outlet of the water purifier 110 and the water inlet of the faucet 120, the water purification system further comprises a controller 130, the controller 130 is electrically connected to the heating mechanism 140, the controller 130 is used to control the opening and closing of the heating mechanism 140, a switch mechanism 150 is arranged between the water outlet of the water purifier 110 and the water inlet of the water purifier 110, the switch mechanism 150 is used to control the conduction and disconnection between the water outlet of the water purifier 110 and the water inlet of the water purifier 110. The water purification system can avoid the phenomenon of repeated starting of the water purifier 110 when the water outlet flow rate of the water purifier 110 is greater than the water outlet flow rate of the pipeline machine, thereby significantly improving the use effect and service life of the water purifier 110.

[0031] It should be noted that if Figures 1 to 3 As shown, a filter element capable of filtering and purifying water should be provided in the water purifier 110. The filter element may be at least one of a melt-blown filter element, a carbon fiber filter element, a carbon rod filter element, and a reverse osmosis membrane, or a combination of two or more thereof. Those skilled in the art should be able to make reasonable selections and designs according to actual conditions, and no specific restrictions are made here. For example, in some embodiments, the filter element of the water purifier 110 may include a reverse osmosis membrane. In this case, the water purifier 110 includes an inlet end for passing tap water into the water purifier 110, an outlet end for discharging purified pure water out of the water purifier 110, and a concentrated water end for discharging concentrated water generated during the purification process out of the water purifier 110; of course, in other embodiments, the filter element of the water purifier 110 may not include a reverse osmosis membrane. In this case, the water purifier 110 includes an inlet end for passing tap water into the water purifier 110 and an outlet end for discharging purified purified water out of the water purifier 110.

[0032] like Figures 1 to 3As shown, the water outlet of the water purifier 110 and the water inlet of the faucet 120 are connected to each other so that the water flowing out of the water outlet of the water purifier 110 can flow into the water inlet of the faucet 120 (and finally flow out through the water outlet of the faucet 120). In addition, a heating mechanism 140 is provided between the water outlet of the water purifier 110 and the water inlet of the faucet 120, so that the water purification system provided by the present application has a heating function, thereby improving the functional diversity of the water purification system. In order to realize the intelligent control of the heating function of the water purification system, the water purification system also includes a controller 130, which is electrically connected to the heating mechanism 140 for controlling the opening and closing of the heating mechanism 140. Specifically, when the controller 130 controls the heating mechanism 140 to be turned on, the water flowing through the heating mechanism 140 can be heated, so that the water inlet end of the faucet 120 is hot water; when the controller 130 controls the heating mechanism 140 to be turned off, the water flowing from the water outlet end of the water purifier 110 into the water inlet end of the faucet 120 is not heated, so that the water inlet end of the faucet 120 is normal temperature water. The faucet 120 can be divided into two separate normal temperature faucets 120 and hot water faucets 120, or it can be a style in which the normal temperature faucet 120 and the hot water faucet 120 are combined into a whole, and the water output of normal temperature water and hot water is controlled by swinging left and right.

[0033] Compared with the method of using a water purifier 110 and a pipeline machine in combination in the prior art, the water purification system composed of a water purifier 110 and a faucet 120 provided in the present application can not only meet the user's heating needs during water use, but also because the distance between the heating mechanism 140 of the water purification system and the water inlet end of the faucet 120 is closer, it can also avoid heat loss caused by the long distance between the heating element of the pipeline machine and the water inlet end of the faucet 120, thereby avoiding the temperature difference between the outlet water temperature of the heating body 142 of the pipeline machine and the water inlet temperature of the water inlet end of the faucet 120 as much as possible.

[0034] like Figures 1 to 3As shown, the water outlet of the water purifier 110 is not only connected to the water inlet of the faucet 120, but also connected to the water inlet of the water purifier 110, so that the water flowing out of the water outlet of the water purifier 110 can flow into the water inlet of the water purifier 110 (i.e., flow back into the water purifier 110). In addition, a switch mechanism 150 is provided between the water outlet of the water purifier 110 and the water inlet of the water purifier 110. The switch mechanism 150 is used to control the conduction and disconnection between the water outlet of the water purifier 110 and the water inlet of the water purifier 110, so as to avoid the phenomenon of repeated startup of the water purifier 110 caused by the inability to match the large-flux water purifier 110 and the existing pipeline machine in the prior art, thereby significantly improving the use effect and service life of the water purifier 110. Specifically, when the water outlet flow rate of the water purifier 110 is less than or equal to the water outlet flow rate of the faucet 120, the switch mechanism 150 can control the water outlet end of the water purifier 110 to be disconnected from the water inlet end of the water purifier 110. At this time, the water flowing out from the water outlet end of the water purifier 110 can only flow into the water inlet end of the faucet 120 to meet the user's water demand; when the water outlet flow rate of the water purifier 110 is greater than the water outlet flow rate of the faucet 120, the switch mechanism 150 can control the water outlet end of the water purifier 110 to be connected to the water inlet end of the water purifier 110. At this time, the water flowing out from the water outlet end of the water purifier 110 can not only flow into the water inlet end of the faucet 120, but also flow into the water inlet end of the water purifier 110 to avoid repeated startup of the water purifier 110. In the actual installation process, the water outlet of the water purifier 110, the water inlet of the faucet 120 and the water inlet of the water purifier 110 can be connected by a three-way joint.

[0035] In some embodiments, Figures 1 to 3 As shown, the heating mechanism 140 includes a flow limiting member and a heating body 142 which are sequentially arranged along the direction from the water outlet of the water purifier 110 to the water inlet of the faucet 120. The controller 130 is electrically connected to the heating body 142. The controller 130 is used to control the opening and closing of the heating body 142. The opening of the flow limiting member can be adjusted according to the actual power of the heating body 142 to limit the flow rate of the flow through the flow limiting member to the water inlet of the faucet 120. Optionally, the flow limiting member is a flow limiting valve 1411 or an adjustable electric valve 1412.

[0036] It should be noted that the heating mechanism 140 includes a heating body 142, which heats water through the heating body 142. Since the actual power of the heating body 142 is certain, the volume of water heated from room temperature to boiling by the heating body 142 per unit time is also certain. In order to avoid the water flow rate through the heating body 142 being too fast (or, to avoid the volume of water passing through the heating body 142 per unit time being too large), which causes the heating body 142 to fail to heat the water to boiling, the heating mechanism 140 also includes a flow limiting member, which is arranged at the front end of the heating body 142 along the direction from the water outlet of the water purifier 110 to the water inlet of the faucet 120, so as to limit the flow rate of water flowing through the flow limiting member to the water inlet of the faucet 120 (or the flow rate of water flowing through the heating body 142), and only allow a unit volume of water to pass through the heating body 142 per unit time. Among them, the opening of the flow limiting member can be adjusted according to the actual power of the heating body 142, so that the flow rate of water flowing through the flow limiting member to the water inlet end of the faucet 120 (or the flow rate of water flowing through the heating body 142) matches the actual power of the heating body 142, thereby ensuring that the heating body 142 can heat all the water to boiling under full power working conditions.

[0037] When the user uses the heating function of the water purification system, in order to avoid the phenomenon of dry burning of the heating body 142 (that is, there is no water in the heating body 142 but the heating body 142 has started to heat), in some embodiments, such as Figures 1 to 3 As shown, the heating mechanism 140 also includes a flow switch 143 disposed between the flow limiting member and the heating body 142 , and the controller 130 is electrically connected to the flow switch 143 , and the controller 130 is used to control the opening and closing of the heating body 142 according to the flow signal obtained by the flow switch 143 .

[0038] Specifically, when the flow switch 143 does not sense the flow, the controller 130 controls the heating body 142 to be in a closed state until the water flowing out of the water outlet of the water purifier 110 passes through the flow switch 143 (flows to the heating body 142). The flow switch 143 can obtain the flow signal and send the flow signal to the controller 130. The controller 130 controls the heating body 142 to turn on according to the received flow signal, and then the heating body 142 can start heating. Since the flow switch 143 obtains the flow signal and sends the flow signal to the controller 130, it takes time for the controller 130 to control the heating body 142 to turn on according to the received flow signal. Therefore, during this process, the water passing through the flow switch 143 can already flow into the heating body 142. In order to further ensure that the heating body 142 will never dry burn, the controller 130 can be set to delay the opening when controlling the heating body 142 to turn on according to the received flow signal.

[0039] In some embodiments, Figures 1 to 3 As shown, the faucet 120 is provided with a temperature regulating mechanism 160, and the controller 130 is electrically connected to the temperature regulating mechanism 160. The controller 130 is used to adjust the actual power of the heating body 142 according to the temperature signal obtained by the temperature regulating mechanism 160. In this way, the user can select different temperatures through the temperature regulating mechanism 160, and the controller 130 adjusts the actual power of the heating body 142 according to the temperature signal obtained by the temperature regulating mechanism 160, so that the heating body 142 can heat water to different temperatures, thereby improving the applicability and practicality of the water purification system.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the switch mechanism 150 includes a one-way pressure switch 151, and the flow direction of the one-way pressure switch 151 is from the water outlet end of the water purifier 110 to the water inlet end of the water purifier 110. A pressure threshold is preset in the controller 130. The controller 130 can be turned on and off according to the comparison result between the actual pressure obtained by the one-way pressure switch 151 and the pressure threshold.

[0041] In this way, when the water outlet flow rate of the water purifier 110 is greater than the water outlet flow rate of the faucet 120, the actual pressure at the water inlet end of the faucet 120 increases. When the actual pressure is higher than the pressure threshold, the one-way pressure switch 151 opens to connect the water outlet end of the water purifier 110 with the water inlet end of the water purifier 110. At this time, part of the water flowing out from the water outlet end of the water purifier 110 flows to the water inlet end of the faucet 120 (and finally flows out through the water outlet end of the faucet 120), and the other part flows to the water inlet end of the water purifier 110 (and merges with the tap water entering the water purifier 110 from the water inlet end of the water purifier 110) and is filtered and purified again through the water purifier 110, thereby avoiding the pressure at the rear end of the high-pressure switch of the water purifier 110 from increasing and disconnecting, causing the water purifier 110 to start and stop repeatedly.

[0042] In other embodiments, Figure 3 As shown, the switch mechanism 150 includes a pressure switch 152, a first solenoid valve 153 and a one-way valve 154 which are sequentially arranged along the direction from the water outlet end of the water purifier 110 to the water inlet end of the water purifier 110. The flow direction of the one-way valve 154 is from the water outlet end of the water purifier 110 to the water inlet end of the water purifier 110. The controller 130 is electrically connected to the pressure switch 152 and the first solenoid valve 153 respectively. A pressure threshold is preset in the controller 130. The controller 130 is used to control the opening and closing of the first solenoid valve 153 according to the comparison result of the pressure signal obtained by the pressure switch 152 and the pressure threshold.

[0043] In this way, when the water flow rate of the water purifier 110 is greater than the water flow rate of the faucet 120, the actual pressure at the water inlet end of the faucet 120 increases, and the pressure switch 152 can detect the actual pressure to obtain a pressure signal and send the pressure signal to the controller 130. When the controller 130 determines that the pressure signal (or the actual pressure) is higher than the pressure threshold, the controller 130 controls the first solenoid valve 153 to open, so that the water outlet end of the water purifier 110 and the water inlet end of the water purifier 110 are connected. At this time, part of the water flowing out from the water outlet of the water purifier 110 flows to the water inlet of the faucet 120 (and finally flows out through the water outlet of the faucet 120), and the other part flows to the water inlet of the water purifier 110 (and merges with the tap water entering the water purifier 110 from the water inlet of the water purifier 110) and passes through the water purifier 110 for filtration and purification again, thereby avoiding the pressure at the rear end of the high-pressure switch of the water purifier 110 to increase and disconnect, causing the water purifier 110 to start and stop repeatedly.

[0044] The above-mentioned pressure threshold needs to be lower than the disconnection pressure of the high-pressure switch of the water purifier 110. Optionally, the value range of the preset pressure threshold in the controller 130 is between 0.1MPa and 0.15MPa. Technical personnel in this field should be able to make reasonable selections and designs based on actual conditions, and no specific restrictions are made here.

[0045] like Figures 1 to 3 As shown, a faucet switch 121 is provided in the faucet 120, a reed switch is provided on the faucet switch 121, a second solenoid valve 122 is provided between the water outlet of the water purifier 110 and the connection between the water inlet of the faucet 120 and the water inlet of the water purifier 110, and the controller 130 is electrically connected to the reed switch and the second solenoid valve 122 respectively, and the controller 130 is used to control the opening and closing of the second solenoid valve 122 according to the switch signal obtained by the reed switch.

[0046] In this way, when the user turns on the faucet 120, the reed switch on the faucet switch 121 can obtain the switch signal and send the switch signal to the controller 130. The controller 130 controls the second solenoid valve 122 to open according to the received switch signal, so that the water outlet of the water purifier 110 and the water inlet of the faucet 120 and the connection between the water inlet of the water purifier 110 are connected, so that the water flowing out of the water outlet of the water purifier 110 can selectively flow to the water inlet of the faucet 120 or the water inlet of the water purifier 110. It is worth noting that the reed switch should include two. When the faucet 120 is divided into a separate normal temperature faucet 120 and a hot water faucet 120, the two reed switches are respectively set with the normal temperature faucet 120 and the hot water faucet 120; when the faucet 120 is a normal temperature faucet 120 and a hot water faucet 120 as a whole, the two reed switches correspond to the normal temperature gear and the hot water gear of the faucet 120 respectively.

[0047] Alternatively, if Figure 2 As shown, the water purification system further includes a pipeline mechanism 170, the pipeline mechanism 170 includes a main pipeline 171 and a first pipeline 172 connected to the main pipeline 171, the water outlet of the water purifier 110 is connected to the water inlet of the faucet 120 through the first pipeline 172, and the heating mechanism 140 is arranged on the first pipeline 172 so that both normal temperature water and hot water can flow out through the first pipeline 172; or Figure 1 and Figure 3 As shown, the pipeline mechanism 170 includes a main pipeline 171 and a second pipeline 173 and a third pipeline 174 respectively connected to the main pipeline 171. A ball valve is provided in the faucet 120 to separate the water inlet end of the faucet 120 into a first flow channel and a second flow channel that are independent of each other. The water outlet end of the water purifier 110 is connected to the first flow channel through the main pipeline 171 and the second pipeline 173, and the water outlet end of the water purifier 110 is connected to the second flow channel through the main pipeline 171 and the third pipeline 174. The heating mechanism 140 is provided on the second pipeline 173 so that hot water can flow out through the second pipeline 173 and normal temperature water can flow out through the third pipeline 174.

[0048] In combination with all the above contents, several different embodiments are listed below to explain the working process of the water purification system:

[0049] In one embodiment, if Figure 1 As shown, the flow limiting component is a flow limiting valve 1411, the switch mechanism 150 is a one-way pressure switch 151, and the pipeline mechanism 170 includes a main pipeline 171 and a second pipeline 173 and a third pipeline 174 respectively connected to the main pipeline 171;

[0050] The outlet flow path of normal temperature water of the water purification system 100: the user opens the normal temperature water faucet 120 (or opens the faucet 120 to the normal temperature water gear), and the faucet valve opens. At this time, the corresponding reed switch on the faucet switch 121 obtains the switch signal and sends the switch signal to the controller 130.
