Wherein:

the connector 210 is provided with a connection interface for connecting the water purifier to a water outlet of a water source. As shown in fig. 2, the water purifier is a filter-ready-to-drink type water purifier, and a connector 210 is used to connect the water purifier to a water outlet of a tap water source. The water outlet of the tap water source can be the water outlet of a tap water pipeline or the water outlet of a water tap. For convenience of installation and use, the water purifier may be directly connected to the water outlet of the faucet 201 by a connector 210, as shown in fig. 2. The faucet 201 may be provided with a valve 202, and the valve 202 is used for controlling the flow and stop of tap water. The valve 202 may be a one-in one-out mechanical valve or a one-in one-out electrically controlled valve. The electrically controlled valve may be a solenoid valve.

As shown in fig. 2, the connector 210 includes at least a first water inlet 211, a first water outlet 212, and a second water outlet 213, and the first water inlet 211 is connected to the first water outlet 212 and the second water outlet 213, respectively. The first water inlet 211 is used for connecting with a water source outlet, and the first water inlet 211 is a tap water inlet. The first water outlet 212 is connected to a first end of a water inlet line 220. The second end of the inlet line 220 is connected to the first end of the outlet line 260 via at least one filter element and a booster pump 250. In one possible embodiment, as shown in fig. 2, the connector 210 may further include a second water inlet 214 and a fourth water outlet 215. The second water inlet 214 is connected to a second end of the water outlet pipe 260, and the second water inlet 214 is directly communicated with the fourth water outlet 215. The tap water is filtered by the at least one filter element to obtain purified water, and the purified water can flow out through the second water inlet 214 and the fourth water outlet 215.

In addition, as shown in fig. 2, the at least one filter element includes: a front filter element 241, a main filter element 242, and a rear filter element 243. Wherein, the second end of the water inlet pipeline 220 is connected with the water inlet of the prepositive filter element 241; the water outlet of the preposed filter element 241 is connected with the water inlet of the booster pump 250; the water outlet of the booster pump 250 is connected with the water inlet of the main filtering element 242; the water outlet of the main filter element 242 is connected with the water inlet of the post-filter element 243; the outlet of the post-filter 243 is connected to a first end of the outlet line 260. The pre-filter 241 may be an activated carbon filter for adsorbing and filtering contaminants, odors, colors, etc. in the tap water. The pressurizing pump 250 serves to pressurize the tap water and supply the pressurized tap water to the main filtering cartridge 242. The main filter element 242 may be a reverse osmosis filter element for filtering heavy metal ions, bacteria, viruses, colloids, radioactive substances, soluble salt ions, various pollutants, etc. harmful to human bodies from the tap water. In order to improve the water purification effect, the main filter element 242 may be further connected to a post-filter element 243. The post-filter 243 may be an activated carbon filter for filtering the water flowing out of the main filter 242 again. Of course, in other possible embodiments, the number of the filter elements, the selection of the filter elements, and the connection structure between the filter elements and the booster pump 250 may be different, for example, a PP cotton filter element may be added before the front filter element 241, or the rear filter element 243 may be omitted, and the embodiment is not particularly limited.

As shown in fig. 2, the water purifier further includes: the valve 203 is electrically controlled. The electrically controlled valve 203 is disposed inside the connector 210. The electrically controlled valve 203 is a valve that is electrically controlled to open/close, such as an electromagnetic valve or an electrically operated valve. The electrically controlled valve 203 is connected to a control circuit 270 through a wire 280, and the control circuit 270 is used for controlling the opening/closing of the electrically controlled valve 203. The electrically controlled valve 203 may be a one-in two-out electrically controlled valve. The electrically controlled valve 203 includes an inlet port, a first outlet port and a second outlet port. Wherein the inlet end is connected to the first inlet 211, the first outlet end is connected to the first outlet 212, and the second outlet end is connected to the second outlet 213.

The control circuit 270 may control the electrically controlled valve 203 to be in the first operating state or the second operating state.

1. When the electrically controlled valve 203 is in the first working state, the passage between the inlet end and the first outlet end of the electrically controlled valve 203 is open, and the passage between the inlet end and the second outlet end is closed. At this time, the tap water is filtered by the water purifier to obtain purified water, and then flows out from the fourth water outlet 215. The flow direction of the water flow is as follows: the water outlet of the water tap 201 → the first water inlet 211 → the inlet end of the electrically controlled valve 203 → the first outlet end of the electrically controlled valve 203 → the first water outlet 212 → the water inlet pipe 220 → the front filter element 241 → the booster pump 250 → the main filter element 242 → the rear filter element 243 → the water outlet pipe 260 → the second water inlet 214 → the fourth water outlet 215.

2. When the electrically controlled valve 203 is in the second working state, the passage between the inlet end and the second outlet end of the electrically controlled valve 203 is open, and the passage between the inlet end and the first outlet end is closed. At this time, the tap water is not filtered by the water purifier, and the tap water directly flows out from the second water outlet 213. The flow direction of the water flow is as follows: the water outlet of the faucet 201 → the first water inlet 211 → the inlet end of the electrically controlled valve 203 → the second outlet end of the electrically controlled valve 203 → the second water outlet 213.

The points to be explained are: by reasonably designing the internal structure of the connector 210 or by means of the resistance action of the filter element to water, it can be ensured that the water outlet passage between the inlet end and the first outlet end of the electric control valve 203 is communicated, and under the condition that the water outlet passage between the inlet end and the second outlet end of the electric control valve 203 is also communicated, the tap water flowing out from the water outlet of the water faucet 201 automatically selects the water outlet passage between the inlet end and the second outlet end of the electric control valve 203 to flow out, that is, the water flow direction is as shown in the above case 2. For example, as shown in fig. 2, by designing the vertical path between the inlet end and the first outlet end of the electrically controlled valve 203, and the vertical path between the inlet end and the second outlet end of the electrically controlled valve 203, when both of the two outlet paths are in the conducting state, the tap water flowing out from the outlet of the faucet 201 will directly flow out from the second outlet 213. For another example, since the filter element inside the water purifier has resistance to water, the tap water flowing out from the water outlet of the faucet 201 will automatically select the path with small resistance, i.e. directly flow out from the second water outlet 213.

Optionally, at least one operation button (not shown) may be further disposed on the connector 210. The at least one operation key is connected to the control circuit 270 through a wire. The at least one operation key is used for realizing the control of the working state of the electric control valve 203 by a user.

As shown in fig. 2, the water purifier further includes: a water flow sensor 230. The water flow sensor 230 is disposed inside the connector 210 or in the water inlet line 220. The water flow sensor 230 is connected to the control circuit 270 by a wire 280. The water flow sensor 230 may be a vane type water flow sensor, and the water flow sensor 230 may detect whether water is present in the pipe in which it is installed. The water flow sensor 230 may also measure the flow rate of water when water is present in the pipe in which the water flow sensor 230 is located.

When the water purifier is in a water making state, the control circuit 270 obtains the water flow condition of the water outlet of the water source through the water flow sensor 230. Thereafter, the control circuit 270 detects whether the water flow condition at the water outlet of the water source satisfies a first predetermined condition. If the first predetermined condition is satisfied, the control circuit 270 controls the booster pump 250 to start operating. Wherein the first predetermined condition is the presence of a flow of water; alternatively, the first predetermined condition is that there is water flow and the water flow rate is greater than a first threshold. When the water flow condition at the water outlet of the water source meets the first preset condition, it indicates that the water source supplies water normally, and at this time, the control circuit 270 controls the booster pump 250 to start working normally, so as to pump water and boost pressure through the booster pump 250, so that the main filtering filter element 242 can filter water. In addition, when the water flow condition at the water outlet of the water source does not meet the first predetermined condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the water flow speed is too low, and at this time, the control circuit 270 does not start the booster pump 250, so as to prevent the booster pump 250 from pumping out the water adsorbed in each filter element, and thus the efficiency of next water production is affected.

In addition, after the control circuit 270 controls the booster pump 250 to start, whether the water flow condition at the water outlet of the water source meets a second preset condition is continuously detected; if the water flow condition at the water outlet of the water source meets the second predetermined condition, the control circuit 270 controls the booster pump 250 to stop working. Wherein the second predetermined condition is the absence of water flow; alternatively, the second predetermined condition is that there is water flow but the water flow rate is less than a second threshold, the second threshold < the first threshold. In the water making process, when the water flow condition at the water outlet of the water source meets the second preset condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the user closes the faucet 201, at this time, the control circuit 270 controls the booster pump 250 to stop working, and the booster pump 250 is prevented from pumping out the water adsorbed in each filter element to influence the water making efficiency next time. In addition, in the water making process, when the water flow condition at the water outlet of the water source does not meet the second preset condition, the water supply of the water source is normal, and the normal work of the booster pump 250 is kept.

In addition, the water purifier that this embodiment provided still acquires the rivers condition of water source delivery port through rivers sensor to detect whether there is rivers or whether velocity of water is greater than first threshold value in the water source delivery port through control circuit, both avoided the booster pump to empty to take out, guaranteed the play velocity of water when the water purifier provides the water purification again, promote user experience. In addition, the water purifier is also provided with a front filter element, a main filter element and a rear filter element, so that the water purifying effect and the water purifying quality of the water purifier are fully ensured.

The points to be explained are: the above-mentioned embodiment shown in fig. 2 is only exemplified by the connector 210 further comprising the second water inlet 214 and the fourth water outlet 215, and the second water inlet 214 is directly communicated with the fourth water outlet 215. In other possible embodiments, the connector 210 may comprise a second water inlet 214, and the water purifier further comprises a three-way connection element (not shown in the figure), a first port of the three-way connection element is connected with the second water inlet 214, a second port of the three-way connection element is connected with the second water outlet 213, and a third port of the three-way connection element is connected with the first water inlet 211 through the electrically controlled valve 203. Like this, can make two water outlet passage sharing same delivery port, the user need not to carry out the selection of delivery port at the water intaking in-process, convenience of customers operation improves user experience.

What needs to be further explained is that: the embodiment shown in fig. 2 is only exemplified by the electrically controlled valve 203 being a one-in two-out electrically controlled valve. In other possible embodiments, the electrically controlled valve 203 may be two in-one out electrically controlled valves, or the electrically controlled valve 203 may also be one in-one out electrically controlled valve. When the electric control valve 203 is two electric control valves with one inlet and one outlet, a three-way connecting element can be arranged in the connector 210, a first port of the three-way connecting element is connected with the first water inlet 211, a second port is connected with the first water outlet 212 through the first electric control valve, and a third port is connected with the second water outlet 213 through the second electric control valve. The control circuit 270 controls the two electric control valves to open or close, so as to switch between two working states. In a first working state, the first electric control valve is opened and the second electric control valve is closed; in a second operating state, the first electrically controlled valve is closed and the second electrically controlled valve is opened. When the electrical valve 203 is an in-out electrical valve, a three-way connecting element may be disposed inside the connector 210, wherein a first port of the three-way connecting element is connected to the first water inlet 211, a second port of the three-way connecting element is connected to the first water outlet 212, and a third port of the three-way connecting element is connected to the second water outlet 213 through the one-in-one-out electrical valve. The control circuit 270 controls the opening or closing of the one in-out electric control valve to realize the switching between two working states of the electric control valve. In a first working state, the electric control valve is closed; in the second working state, the electric control valve is opened.

Optionally, the water purifier may further include a water inlet electric control valve and a water outlet electric control valve. Wherein, the water inlet electric control valve can be arranged in the water inlet pipeline 220 or in a pipeline between the pre-filter element 241 and the booster pump 250. The water inlet electric control valve can be an electromagnetic valve. When the water inlet electric control valve is opened, the water purifier allows tap water to flow in, and starts to produce water; when the water inlet electric control valve is closed, the water purifier does not allow tap water to flow in, and the water purifier stops producing water. An electrically controlled valve for water outlet may be disposed in the water outlet line 260. The water outlet electric control valve can be an electromagnetic valve. The water outlet electric control valve is used for controlling the outflow of purified water, and the water outlet electromagnetic valve is opened in the water preparation process; when water production is stopped, the water outlet electromagnetic valve is closed.

Fig. 3 is a schematic structural view illustrating a water purifier according to still another exemplary embodiment, which may include: a connector 310, a water inlet line, a water flow sensor 330, at least one filter element 340, a booster pump 350, a water outlet line 360, a control circuit 370, and a wire 380. Wherein:

the connector 310 includes at least a first water inlet 311, a first water outlet 312, and a second water outlet 313, and the first water inlet 311 is connected to the first water outlet 312 and the second water outlet 313, respectively. The first outlet 312 is connected to a first end of the water inlet line. The second end of the water inlet line is connected to the first end of the water outlet line 360 via at least one filter element 340 and a booster pump 350.

The water flow sensor 330 is disposed inside the connector 310 or in the water inlet line.

The control circuit 370 is connected to the water flow sensor 330 and the booster pump 350 by wires 380, respectively.

In contrast to the embodiment shown in fig. 2: in this embodiment, the water purifier further includes a water storage tank 390. The water storage tank 390 is used to store a certain amount of tap water for use when the water supply source cannot normally supply water.

As shown in FIG. 3, the water inlet circuit includes a first water inlet circuit 321 and a second water inlet circuit 322. Wherein, the first end of the first water inlet pipeline 321 is connected with the first water outlet 312; the second end of the first water inlet pipe 321 is connected with the water inlet of the water storage tank 390; the water outlet of the water storage tank 390 is connected with the first end of the second water inlet pipeline 322; the second end of the second water inlet pipeline 322 is connected with the first end of the water outlet pipeline 360 through at least one filter element 340 and the booster pump 350.

1. When the water source can normally supply water, the water outlet passage of the purified water is as follows: the water outlet of the water tap 301 → the first water inlet 311 → the inlet end of the electrically controlled valve 303 → the first outlet end of the electrically controlled valve 303 → the first water outlet 312 → the first water inlet pipe 321 → the water storage tank 390 → the second water inlet pipe 322 → the at least one filter element 340 → the booster pump 350 → the water outlet pipe 360 → the second water inlet 314 → the fourth water outlet 315.

2. When the water source can not normally supply water, but the water storage tank 390 can normally supply water, the water outlet path of the purified water is as follows: the water storage tank 390 → the second water inlet pipe 322 → at least one filter element 340 → the pressurizing pump 350 → the water outlet pipe 360 → the second water inlet 314 → the fourth water outlet 315.

In addition, in one possible embodiment, the water purifier further includes a stored water flow sensor 391. The stored water flow sensor 391 is disposed in the second water inlet pipe 322, and the stored water flow sensor 391 is connected to the control circuit 370 through a wire 380. The stored water flow sensor 391 may be an impeller-type water flow sensor. A stored water flow sensor 391 is used to detect the presence of water flow in the second water inlet line 322. The stored water flow sensor 391 may also measure the flow rate of water in the second water inlet line 322 when water is present in the second water inlet line 322.

When the water purifier is in a water production state, the control circuit 370 acquires the water flow condition of the water outlet of the water source through the water flow sensor 330. Thereafter, the control circuit 370 detects whether the water flow condition at the water outlet of the water source meets a first predetermined condition. If the first predetermined condition is satisfied, the control circuit 370 controls the booster pump 350 to start operating. Wherein the first predetermined condition is the presence of a flow of water; alternatively, the first predetermined condition is that there is water flow and the water flow rate is greater than a first threshold. When the water flow condition at the water outlet of the water source meets the first preset condition, it indicates that the water source supplies water normally, and at this time, the control circuit 370 controls the booster pump 350 to start working normally, so as to pump water and boost pressure through the booster pump 350, and filter the water for the filter element 340.

In addition, when the water flow condition at the water outlet of the water source does not satisfy the first predetermined condition, the control circuit 370 obtains the water flow condition at the water outlet of the water storage tank 390 through the water storage flow sensor 391. Thereafter, the control circuit 370 detects whether the water flow condition at the water outlet of the water storage tank 390 meets a third predetermined condition; if the third predetermined condition is satisfied, the control circuit 370 controls the booster pump 350 to start operating. Wherein the third predetermined condition is that water flow is present, or the third predetermined condition is that water flow is present and the water flow rate is greater than a third threshold. When the water flow condition at the water outlet of the water source does not meet the first predetermined condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the water flow speed is too low, and at this time, the water storage water flow sensor 391 detects whether the water storage tank 390 can supply water normally. When the water flow condition at the water outlet of the water storage tank 390 meets the third predetermined condition, it indicates that the water storage tank 390 can supply water normally, and at this time, the control circuit 370 controls the booster pump 350 to start up normally, so as to pump water and boost water through the booster pump 350, so as to filter the filter element 340. When the water flow condition at the water outlet of the water storage tank 390 does not satisfy the third predetermined condition, it indicates that the water storage tank 390 cannot supply water normally, the reason may be that there is no tap water or the water amount is insufficient in the water storage tank 390, and at this time, the control circuit 370 does not start the booster pump 350, so as to prevent the booster pump 350 from pumping out the water adsorbed in each filter element to affect the efficiency of water production next time.

In addition, after the control circuit 370 controls the booster pump 350 to start, it continues to detect whether the water flow condition at the water outlet of the water storage tank 390 meets a fourth predetermined condition; if the water flow condition at the water outlet of the water storage tank 390 meets the fourth predetermined condition, the control circuit 370 controls the booster pump 350 to stop working. Wherein the fourth predetermined condition is the absence of water flow; alternatively, the fourth predetermined condition is that there is water flow but the water flow rate is less than a fourth threshold, the fourth threshold < the third threshold. In the process of water production, when the water flow condition at the water outlet of the water storage tank 390 meets the fourth predetermined condition, it indicates that the water storage tank 390 cannot supply water normally, the reason may be that the water in the water storage tank 390 is used up or insufficient, at this time, the control circuit 370 controls the booster pump 350 to stop working, and the booster pump 350 is prevented from pumping out the water adsorbed in each filter element, which affects the efficiency of water production next time. In addition, in the process of water production, when the water flow condition at the water outlet of the water storage tank 390 does not satisfy the fourth predetermined condition, it indicates that the water supply of the water storage tank 390 is normal, and the booster pump 350 is kept working normally under the condition that the user does not trigger the stop of water production.

In another possible embodiment, the water purifier further includes a water pressure sensor 392. The water pressure sensor 392 is disposed inside the water storage tank 390, and the water pressure sensor 392 is connected to the control circuit 370 through the wire 380. Water pressure sensor 392 is used to measure the water pressure within tank 390. The water pressure value in the water storage tank 390 reflects the amount of water stored in the water storage tank 390, and the water pressure value and the amount of water stored are in a positive correlation. The higher the water pressure value is, the more the water is stored; conversely, the lower the water pressure value, the less the amount of stored water.

In addition, when the water flow condition at the water outlet of the water source does not satisfy the first predetermined condition, the control circuit 370 obtains the water pressure value in the water storage tank 390 through the water pressure sensor 392. Thereafter, the control circuit 370 detects whether the water pressure value is greater than a first water pressure threshold value; if the pressure is greater than the first water pressure threshold value, the control circuit 370 controls the booster pump 350 to start working. When the water flow condition at the water outlet of the water source does not satisfy the first predetermined condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the water flow speed is too low, and at this time, the water pressure sensor 392 detects the water pressure value inside the water storage tank 390. When the water pressure value inside the water storage tank 390 is greater than the first water pressure threshold value, it indicates that the water storage tank 390 can supply water normally, and at this time, the control circuit 370 controls the booster pump 350 to start working normally, so as to pump water and boost pressure through the booster pump 350, so as to filter the filter element 340. When the water pressure value inside the water storage tank 390 is smaller than the first water pressure threshold value, it indicates that the water storage tank 390 cannot supply water normally, the reason may be that there is no tap water or the water amount is insufficient in the water storage tank 390, and the control circuit 370 does not start the booster pump 350 at this time, so as to prevent the booster pump 350 from pumping out the water adsorbed in each filter element, which affects the efficiency of water making next time.

In addition, after the control circuit 370 controls the booster pump 350 to start, it continues to detect whether the water pressure value inside the water storage tank 390 is smaller than a second water pressure threshold value, which is smaller than the first water pressure threshold value; if the water pressure value inside the water storage tank 390 is less than the second water pressure threshold value, the control circuit 370 controls the booster pump 350 to stop working. In the water making process, when the water pressure value inside the water storage tank 390 is smaller than the second water pressure threshold value, it indicates that the water storage tank 390 cannot supply water normally, the reason may be that the water amount in the water storage tank 390 is used up or insufficient, at this time, the control circuit 370 controls the booster pump 350 to stop working, and the booster pump 350 is prevented from pumping out the water adsorbed in each filter element, which affects the water making efficiency next time. In addition, in the water production process, when the water pressure value inside the water storage tank 390 is greater than the second water pressure threshold value, it indicates that the water supply of the water storage tank 390 is normal, and the booster pump 350 is kept working normally under the condition that the user does not trigger the stop of water production.

In addition, the water purifier that this embodiment provided still through add the storage water tank in water purifier inside, when the unable normal water supply of water source, through the running water that prestores in the storage water tank maintain the normal system water of water purifier, ensure that the user still can take a quantitative pure water when the unable normal water supply of water source, fully improved user experience.

The points to be explained are: in the water purifier shown in fig. 3, it is exemplified that the water purifier includes both the stored water flow sensor 391 and the water pressure sensor 392. In practical cases, the water purifier only needs to include any one of the stored water flow sensor 391 and the water pressure sensor 392, and can detect the amount of water inside the water storage tank 390.

What needs to be further explained is that: the number of the control circuits 370 may be one or plural. For example, the control circuit 370 may include a first control circuit and a second control circuit. The first control circuit and the second control circuit are connected through a lead. The first control circuit is respectively connected with the water flow sensor 330 and the electrically controlled valve 303 through leads and is used for controlling the water flow sensor 330 and the electrically controlled valve 303. The second control circuit is respectively connected with the booster pump 350 and the stored water flow sensor 391 through leads and is used for controlling the booster pump 350 and the stored water flow sensor 391. Alternatively, the second control circuit is connected to the booster pump 350 and the water pressure sensor 392 through wires, respectively, for controlling the booster pump 350 and the water pressure sensor 392.

Fig. 4 is a schematic structural view illustrating a water purifier according to still another exemplary embodiment, which may include: a connector 410, an inlet line 420, a water flow sensor 430, at least one filter cartridge 440, a booster pump 450, an outlet line 460, a control circuit 470, and a wire 480. Wherein:

the connector 410 includes at least a first water inlet 411, a first water outlet 412 and a second water outlet 413, and the first water inlet 411 is connected to the first water outlet 412 and the second water outlet 413, respectively. The first outlet 412 is connected to a first end of the inlet pipe 420. The second end of the inlet conduit 420 is connected to the first end of the outlet conduit 460 via at least one filter element 440 and a booster pump 450.

The water flow sensor 430 is disposed inside the connector 410 or in the water inlet line 420.

The control circuit 470 is connected to the water flow sensor 430 and the booster pump 450 by wires 480, respectively.

As shown in fig. 4, the water purifier further includes a water storage tank 490. The water storage tank 490 is used to store a certain amount of tap water for use when the water supply source is unable to supply water normally.

In contrast to the embodiment shown in fig. 3: in this embodiment, the water purifier further includes a first water inlet pipeline 493 and a second water inlet pipeline 494, and the connector 410 further includes a third water outlet 416. Wherein the third water outlet 416 is connected to a first end of the first water storage inlet pipeline 493; a second end of the first water storage and inlet pipeline 493 is connected with a water inlet of the water storage tank 490; the water outlet of the water storage tank 490 is connected to a first end of a second water storage inlet pipe 494; a second end of the second stored water inlet conduit 494 is connected to a first end of the water outlet conduit 460 via at least one filter element 440 and a booster pump 450.

1. When the water source can normally supply water, the water outlet passage of the purified water is as follows: the water outlet of the water tap 401 → the first water inlet 411 → the inlet end of the electrically controlled valve 403 → the first outlet end of the electrically controlled valve 403 → the first water outlet 412 → the water inlet pipe 420 → at least one filter element 440 → the booster pump 450 → the water outlet pipe 460 → the second water inlet 414 → the fourth water outlet 415.

2. When the water source cannot normally supply water, but the water storage tank 490 can normally supply water, the water outlet path of the purified water is as follows: water storage tank 490 → second water storage and inlet line 494 → at least one filter core 440 → booster pump 450 → water outlet line 460 → second water inlet 414 → fourth water outlet 415.

In addition, in one possible embodiment, the water purifier further includes a stored water flow sensor 491. A stored water flow sensor 391 is disposed in the second stored water inlet line 494, and a stored water flow sensor 491 is connected to the control circuit 470 via a wire 480. The stored water flow sensor 491 may be an impeller type flow sensor. The stored water flow sensor 491 is used to detect whether water flow is present in the second stored water inlet line 494. The stored water flow sensor 491 is also operable to measure the flow rate of water flowing through the second stored water inlet line 494 when water is present in the second stored water inlet line 494.

When the water purifier is in a water production state, the control circuit 470 acquires the water flow condition of the water outlet of the water source through the water flow sensor 430. Then, the control circuit 470 detects whether the water flow condition at the water outlet of the water source meets a first predetermined condition. If the first predetermined condition is satisfied, the control circuit 470 controls the booster pump 450 to start operating. Wherein the first predetermined condition is the presence of a flow of water; alternatively, the first predetermined condition is that there is water flow and the water flow rate is greater than a first threshold. When the water flow condition at the water outlet of the water source meets the first preset condition, the water source supplies water normally, at the moment, the control circuit 470 controls the booster pump 450 to start working normally, and water is pumped and pressurized through the booster pump 450 to be filtered by the filter element 440.

In addition, when the water flow condition at the water outlet of the water source does not meet the first predetermined condition, the control circuit 470 acquires the water flow condition at the water outlet of the water storage tank 490 through the water storage flow sensor 491. Then, the control circuit 470 detects whether the water flow condition at the water outlet of the water storage tank 490 meets a third predetermined condition; if the third predetermined condition is satisfied, the control circuit 470 controls the booster pump 450 to start operating. Wherein the third predetermined condition is that water flow is present, or the third predetermined condition is that water flow is present and the water flow rate is greater than a third threshold. When the water flow condition at the water outlet of the water source does not meet the first predetermined condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the water flow speed is too low, and at this time, the water storage flow sensor 491 detects whether the water storage tank 490 can supply water normally. When the water flow condition at the water outlet of the water storage tank 490 meets the third predetermined condition, it indicates that the water storage tank 490 can supply water normally, and at this time, the control circuit 470 controls the booster pump 450 to start working normally, so as to pump water and boost water through the booster pump 450, so as to filter the filter element 440. When the water flow condition at the water outlet of the water storage tank 490 does not satisfy the third predetermined condition, it indicates that the water storage tank 490 cannot supply water normally, the reason may be that there is no tap water or the water amount is insufficient in the water storage tank 490, and at this time, the control circuit 470 does not start the booster pump 450, so as to prevent the booster pump 450 from pumping out the water adsorbed in each filter element, which affects the efficiency of water production next time.

In addition, after the control circuit 470 controls the booster pump 450 to start, whether the water flow condition at the water outlet of the water storage tank 490 meets a fourth predetermined condition is continuously detected; if the water flow condition at the outlet of the water storage tank 490 meets the fourth predetermined condition, the control circuit 470 controls the booster pump 450 to stop working. Wherein the fourth predetermined condition is the absence of water flow; alternatively, the fourth predetermined condition is that there is water flow but the water flow rate is less than a fourth threshold, the fourth threshold < the third threshold. In the water making process, when the water flow condition at the water outlet of the water storage tank 490 meets the fourth predetermined condition, it indicates that the water storage tank 490 cannot supply water normally, the reason may be that the water in the water storage tank 490 is used up or insufficient, and the control circuit 470 controls the booster pump 450 to stop working at this time, so as to prevent the booster pump 450 from pumping out the water adsorbed in each filter element, which affects the water making efficiency next time. In addition, in the water making process, when the water flow condition at the water outlet of the water storage tank 490 does not meet the fourth predetermined condition, it indicates that the water supply of the water storage tank 490 is normal, and under the condition that the user does not trigger the stop of water making, the booster pump 450 is kept to work normally.

In another possible embodiment, the water purifier further includes a water pressure sensor 492. The water pressure sensor 492 is disposed inside the water storage tank 490, and the water pressure sensor 492 is connected to the control circuit 470 through a wire 480. Water pressure sensor 492 is used to measure the water pressure within tank 490. The water pressure value in the water storage tank 490 reflects the amount of water stored in the water storage tank 490, and the water pressure value and the amount of water stored are in a positive correlation. The higher the water pressure value is, the more the water is stored; conversely, the lower the water pressure value, the less the amount of stored water.

In addition, when the water flow condition at the water outlet of the water source does not satisfy the first predetermined condition, the control circuit 470 obtains the water pressure value in the water storage tank 490 through the water pressure sensor 492. Thereafter, the control circuit 470 detects whether the water pressure value is greater than a first water pressure threshold value; if the pressure is greater than the first water pressure threshold, the control circuit 470 controls the booster pump 450 to start operation. When the water flow condition at the water outlet of the water source does not satisfy the first predetermined condition, it indicates that the water source cannot supply water normally, the reason may be that the water source stops supplying water or the water flow rate is too low, and at this time, the water pressure sensor 492 detects the water pressure value inside the water storage tank 490. When the water pressure value inside the water storage tank 490 is greater than the first water pressure threshold value, it indicates that the water storage tank 490 can supply water normally, and at this time, the control circuit 470 controls the booster pump 450 to start working normally, so as to pump water and boost water through the booster pump 450, and filter the water for the filter element 440. When the water pressure value inside the water storage tank 490 is smaller than the first water pressure threshold value, it indicates that the water storage tank 490 cannot supply water normally, because there may be no tap water or insufficient water in the water storage tank 490, the control circuit 470 does not start the booster pump 450 at this time, and the booster pump 450 is prevented from pumping out the water adsorbed in each filter element, which affects the efficiency of water production next time.

In addition, after the control circuit 470 controls the booster pump 450 to start, it continues to detect whether the water pressure value inside the water storage tank 490 is smaller than a second water pressure threshold value, which is smaller than the first water pressure threshold value; if the water pressure value inside the water storage tank 490 is less than the second water pressure threshold value, the control circuit 470 controls the booster pump 450 to stop working. In the water making process, when the water pressure value inside the water storage tank 490 is smaller than the second water pressure threshold value, it indicates that the water storage tank 490 cannot supply water normally, the reason may be that the water in the water storage tank 490 is used up or insufficient, and the control circuit 470 controls the booster pump 450 to stop working at this time, so as to prevent the booster pump 450 from pumping out the water adsorbed in each filter element, which affects the water making efficiency next time. In addition, in the water making process, when the water pressure value inside the water storage tank 490 is greater than the second water pressure threshold value, it indicates that the water supply of the water storage tank 490 is normal, and in the case that the user does not trigger the stop of water making, the booster pump 450 is kept to work normally.

In addition, the water purifier that this embodiment provided still through add the storage water tank in water purifier inside, when the unable normal water supply of water source, through the running water that prestores in the storage water tank maintain the normal system water of water purifier, ensure that the user still can take a quantitative pure water when the unable normal water supply of water source, fully improved user experience. The two embodiments of fig. 4 and fig. 3 provide two different connection structures of the water storage tank, and in practical application, any one of the connection structures can be selected according to practical requirements.

The points to be explained are: in the water purifier shown in fig. 4, the water purifier is exemplified by including both the stored water flow sensor 491 and the water pressure sensor 492. In practical cases, the water purifier can detect the amount of water inside the water storage tank 490 only by including any one of the stored water flow sensor 491 and the water pressure sensor 492.
