Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to water purifiers. Background Technology

[0002] With the advancement of technology, water purifiers have gradually become a necessity in households. Water purifiers purify water, providing users with purified drinking water. The purified water is stored in the water purifier's tank, which can be removed from the main unit for easy access when needed.

[0003] Monitoring the water level in the water purifier's tank is crucial for ensuring stable operation, as its accuracy directly impacts core functions such as water production control, overflow prevention, and filter lifespan management. Currently, the commonly used water level detection methods in the industry still suffer from insufficient accuracy. Deviations can lead to misjudgments of the water tank's status (such as false alarms for water shortage or failure to detect overflow), resulting in abnormal start-up and shutdown of the water purifier and water waste. While various existing water level detection methods exist, none have effectively resolved the challenge of balancing accuracy and reliability, hindering further improvements in the intelligence level of water purifiers.

[0078] In the aforementioned water purifier, the purified water storage chamber and the liquid level communication chamber together form a "communicating vessel structure," ensuring that the liquid level difference between the two chambers is maintained solely by static pressure. This guarantees that the liquid level difference between the two chambers always approaches zero and also eliminates interference from dynamic water flow on the liquid level sensor. Therefore, according to the water purifier of this application, since the liquid level in the liquid level communication chamber is dynamically balanced with the liquid level in the purified water storage chamber in real time, the error between the liquid level height in the communication chamber and the liquid level height in the purified water storage chamber is effectively eliminated, thereby improving the accuracy of the purified water level monitor in detecting the liquid level in the purified water storage chamber.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0101] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0102] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0103] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0104] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0105] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0106] Combination Figure 1 and Figure 2 ,as well as Figure 13 and Figure 15 As shown, the water purifier according to some embodiments of this application includes a main unit base 1000, a filter assembly 5000, a purified water tank 2000, and a purified water level monitor 4000. The purified water level monitor 4000 is mounted on the main unit base 1000. In addition, the purified water tank 2000 is detachably mounted on the main unit base 1000, so that the purified water tank 2000 can be installed on the main unit base 1000 or can be detached from the main unit base 1000.

[0107] The filter assembly 5000 is configured to filter raw water, allowing the raw water to be filtered and treated to obtain purified water, thus achieving the effect of purified water from the drinking water purifier. The purified water tank 2000 contains a purified water storage chamber 2001, and also includes an outlet 2201, a first interface 2203a, and a second interface 2203b. The outlet 2201, the first interface 2203a, and the second interface 2203b are all connected to the purified water storage chamber 2001. Both the first interface 2203a and the second interface 2203b are located at the bottom of the purified water tank 2000. The first interface 2203a is connected to the outlet 5001 of the filter assembly 5000, allowing the purified water obtained after filtration to enter the purified water storage chamber 2001 through the first interface 2203a. Furthermore, since the water tank 2000 is detachably mounted on the main unit 1000 and the outlet 2201 is connected to the water storage chamber 2001, the user can remove the water tank 2000 from the main unit 1000 and pour out the purified water stored in the water storage chamber 2001 through the outlet 2201.

[0108] The liquid level monitor 4000 includes a liquid level communication cavity 4100 and a liquid level sensor 4200, and the liquid level communication cavity 4100 is connected to the second interface 2203b. During the process of the water purifier dispensing purified water, the purified water discharged from the filter assembly 5000 through the filter outlet 5001 first enters the purified water storage cavity 2001 through the first interface 2203a, and then the purified water in the purified water storage cavity 2001 enters the liquid level communication cavity 4100 through the second interface 2203b, so that the purified water storage cavity 2001 and the liquid level communication cavity 4100 together form a "communicating vessel structure". In this way, by monitoring the liquid level status in the liquid level communication cavity 4100 through the liquid level sensor 4200, the liquid level status in the purified water storage cavity 2001 can be monitored.

[0109] For example, in combination Figure 1 and Figure 2 ,as well as Figures 13 to 19 As shown, in some embodiments of this application, since both the first interface 2203a and the second interface 2203b are connected to the purified water storage chamber 2001, and the first interface 2203a is connected to the filter outlet 5001 of the filter assembly 5000, and the second interface 2203b is connected to the liquid level communication chamber 4100, and in the height direction of the water purifier, the bottom of the liquid level communication chamber 4100 is at the same horizontal line as the second interface 2203b, or the bottom of the liquid level communication chamber 4100 is higher than the second interface 2203b, the purified water storage chamber 2001 and the liquid level communication chamber 4100 together constitute a "communicating vessel structure," thereby ensuring that the liquid level in the purified water storage chamber 2001 and the liquid level communication chamber 4100 is dynamically balanced in real time.

[0110] It is worth noting that during the water purification process, raw water is filtered by the filter assembly 5000 to produce purified water. After the purified water exits the filter assembly 5000 through the filter outlet 5001, it must first enter the purified water storage chamber 2001 through the first interface 2203a, so that the purified water storage chamber 2001 begins to store purified water. Since the first interface 2203a is located at the bottom of the purified water tank 2000, the liquid level in the purified water storage chamber 2001 gradually rises from the bottom of the purified water storage chamber 2001 during the process of storing purified water. Furthermore, since the second interface 2203b is also located at the bottom of the water tank 2000, and the liquid level connecting cavity 4100 is higher than the second interface 2203b, the water storage cavity 2001 and the liquid level connecting cavity 4100 together form a "communicating vessel structure". This means that the water flowing into the liquid level connecting cavity 4100 must flow into the water storage cavity 2001. As the liquid level in the water storage cavity 2001 gradually rises, the liquid level in the liquid level connecting cavity 4100 can also gradually rise from the bottom of the liquid level connecting cavity 4100, thus achieving the effect that the liquid level height in the liquid level connecting cavity 4100 changes with the liquid level height in the water storage cavity 2001.

[0111] For example, in related technologies, the monitoring device used to monitor the liquid level in the water purification tank is placed directly inside the water purification storage chamber of the water purification tank, or the monitoring device is set at the front end of the water purification storage chamber (i.e., the purified water flowing into the water purification storage chamber must first flow through the monitoring device). In this way, during the monitoring process of the monitoring device monitoring the liquid level in the water purification storage chamber, the monitoring device is easily disturbed by the dynamic water flow, thus making it impossible to accurately monitor the liquid level status in the water purification storage chamber.

[0112] It is important to understand that, since the purified water storage chamber 2001 and the liquid level communication chamber 4100 together constitute a "communicating vessel structure," the liquid level difference between the purified water storage chamber 2001 and the liquid level communication chamber 4100 is maintained solely by static pressure. This ensures that the liquid level difference between the purified water storage chamber 2001 and the liquid level communication chamber 4100 always approaches zero, while also eliminating interference from dynamic water flow on the liquid level sensor 4200. Therefore, according to the water purifier of this application, since the liquid level state of the liquid level communication chamber 4100 and the liquid level state in the purified water storage chamber 2001 are dynamically balanced in real time, the error between the liquid level height in the liquid level communication chamber 4100 and the liquid level height in the purified water storage chamber 2001 is effectively eliminated, thereby improving the accuracy of the purified water level monitor 4000 in monitoring the liquid level in the purified water storage chamber 2001.

[0113] Combination Figure 5 and Figure 13 As shown, in some embodiments of this application, the central axis of the first interface 2203a is parallel to the central axis of the second interface 2203b, and both the central axes of the first interface 2203a and the second interface 2203b extend along the height direction of the water purifier. Thus, during the process of the water purifier drawing purified water, as the purified water discharged through the filter outlet 5001 flows into the purified water storage chamber 2001 through the first interface 2203a, the purified water flows from bottom to top, allowing it to flow into the purified water storage chamber 2001 through the first interface 2203a. Then, as the purified water flows through the second interface 2203b, it flows from top to bottom, allowing the purified water in the purified water storage chamber 2001 to flow into the liquid level communication chamber 4100. It is important to understand that during the flow of purified water through the first interface 2203a, the flow direction of the purified water (from bottom to top) is opposite to the direction of gravity, thus forcing the water to rise smoothly in a laminar flow state and avoiding eddies or turbulence caused by horizontal flow. At the same time, during the flow of purified water through the second interface 2203b, the flow direction of the purified water (from top to bottom) is the same as the direction of gravity. This fully utilizes the gravitational potential energy to increase the flow velocity of the purified water and accelerate the liquid level difference between the purified water storage chamber 2001 and the liquid level communication chamber 4100 to approach zero.

[0114] In some embodiments of this application, the size of the first interface 2203a is A1, and the size of the second interface 2203b is A2, satisfying the relationship: A1 = A2. Since the size of the first interface 2203a is equal to the size of the second interface 2203b, during the water purification process, the instantaneous flow rate of purified water flowing from the first interface 2203a into the purified water storage chamber 2001 is equal to the instantaneous flow rate of purified water flowing into the liquid level communication chamber 4100 through the second interface 2203b. This ensures that the liquid level rise rate of the purified water storage chamber 2001 and the liquid level communication chamber 4100 is completely synchronized, guaranteeing a real-time dynamic balance of the liquid level states in the purified water storage chamber 2001 and the liquid level communication chamber 4100.

[0115] In some embodiments of this application, the volume of the purified water storage chamber 2001 is V1, and the volume of the liquid level communication chamber 4100 is V2, satisfying the relationship: V1 > V2. For example, since the purified water storage chamber 2001 and the liquid level communication chamber 4100 together constitute a "communicating vessel structure," and V1 > V2, during the water purification process, the small volume design of the liquid level communication chamber 4100 allows for a higher response speed to changes in liquid level. More specifically, taking V1 = 10V2 as an example, that is, the volume of the purified water storage chamber 2001 is ten times the volume of the liquid level communication chamber 4100, and the depth of the liquid level communication chamber 4100 is set to be consistent with the depth of the purified water storage chamber 2001, thus making the lateral cross-sectional area of ​​the purified water storage chamber 2001 ten times the lateral cross-sectional area of ​​the liquid level communication chamber 4100. Thus, hypothetically, if the same volume of purified water is injected into the purified water storage chamber 2001 and the liquid level communication chamber 4100 respectively, the rate of change of the liquid level in the liquid level communication chamber 4100 is ten times that of the purified water storage chamber 2001. Therefore, according to the water purifier of this application, by setting the volume of the purified water storage chamber 2001 to be larger than the volume of the liquid level communication chamber 4100, the liquid level change in the liquid level communication chamber 4100 has a higher responsiveness. Thus, at the same moment, the liquid level difference between the purified water storage chamber 2001 and the liquid level communication chamber 4100 rapidly approaches zero.

[0116] Combination Figure 13 ,as well as Figures 16 to 19 As shown, in some embodiments of this application, along the height direction of the water purifier, the highest liquid level line of the liquid level communication cavity 4100 is lower than the highest liquid level line of the purified water storage cavity 2001 to prevent overflow of the purified water storage cavity 2001.

[0117] For example, in some embodiments of this application, the water purification tank 2000 can be configured to have two states, which can be set to a locked state and an unlocked state, respectively. When the water purification tank 2000 is in the locked state, the outlet 2201 is sealed, and the outlet 2201 cannot be used to allow liquid in the water purification storage chamber 2001 to flow out. When the water purification tank 2000 is in the unlocked state, the liquid in the water purification storage chamber 2001 can flow to the outside through the outlet 2201. For example, during the water purification process, and when the water purification tank 2000 is in the unlocked state, due to the fast exhaust speed of the water purification storage chamber 2001, the flow rate of purified water flowing into the water purification storage chamber 2001 is fast, posing a risk that the change in the liquid level height of the water purification storage chamber 2001 is faster than the change in the liquid level height of the liquid level communication chamber 4100. In other words, during the water purification process, at any given time, there may be a risk that the liquid level height of the water purification storage chamber 2001 is higher than the liquid level height of the liquid level communication chamber 4100. By setting the highest liquid level line of the liquid level communication cavity 4100 to be lower than the highest liquid level line of the purified water storage cavity 2001, the actual highest liquid level in the purified water storage cavity 2001 is not reached when the liquid level in the liquid level communication cavity 4100 reaches the highest liquid level line, thus preventing overflow of the purified water storage cavity 2001. It should be understood that when the liquid level sensor 4200 detects that the liquid level in the liquid level communication cavity 4100 has reached the highest liquid level line, the water purifier stops producing water, preventing purified water from being supplied to the purified water storage cavity 2001 and thus preventing overflow. For example, in some embodiments of this application, the highest liquid level line of the purified water storage cavity 2001 can be at the same height as the outlet 2201, thus preventing purified water in the purified water storage cavity 2001 from overflowing from the outlet 2201.

[0118] Combination Figure 13 ,as well as Figures 16 to 19 As shown, in some embodiments of this application, when the water purifier provides purified water only through the purified water tank 2000 and not through the water outlet, it is only necessary to monitor the high water level of the purified water tank 2000 (to avoid overflow). Alternatively, in other embodiments where only the high water level needs to be monitored through the liquid level communication cavity, it is only necessary to set a high water level monitor in the liquid level communication cavity 4100. Thus, along the height direction of the water purifier, the bottom of the liquid level communication cavity 4100 is higher than the bottom of the purified water storage cavity 2001. Therefore, when the liquid level in the liquid level communication cavity 4100 drops to the bottom of the liquid level communication cavity 4100, it can also be understood as the moment when the liquid in the liquid level communication cavity 4100 is emptied, at which time the purified water storage cavity 2001 still retains a certain height of purified water.

[0119] Combination Figure 13 ,as well as Figures 16 to 19As shown, in some embodiments of this application, both the first interface 2203a and the second interface 2203b are selectively connected. When the purified water tank 2000 is installed on the main unit 1000, the first interface 2203a is connected and communicates with the filter outlet 5001 of the filter assembly 5000, and the second interface 2203b is connected and communicates with the liquid level communication cavity 4100. Thus, when the purified water tank 2000 is installed on the main unit 1000, the purified water produced by the filter assembly 5000 can flow into the purified water storage cavity 2001 for storage, and the purified liquid level monitor 4000 is used to monitor the liquid level status in the purified water storage cavity 2001. When the water tank 2000 is removed from the main unit 1000, both the first interface 2203a and the second interface 2203b are closed. This ensures that when the water tank 2000 is detached from the main unit 1000, the liquid in the water storage chamber 2001 is prevented from leaking from the first interface 2203a and the liquid in the water storage chamber 2001 is prevented from leaking from the second interface 2203b.

[0120] In some embodiments of this application, the first interface 2203a is configured to be selectively open, and the liquid flow direction in the first interface 2203a is from the filter outlet 5001 to the purified water storage chamber 2001. Exemplarily, when the purified water tank 2000 is installed on the main unit 1000, the first interface 2203a is open to communicate with the filter outlet 5001 of the filter assembly 5000, and during the water purifier's operation, purified water can flow from the filter outlet 5001 towards the purified water storage chamber 2001. Therefore, according to the water purifier of this application, when the purified water tank 2000 is assembled on the main unit 1000, purified water discharged from the filter outlet 5001 can flow into the purified water storage chamber 2001 for storage through the first interface 2203a. Thus, during the water purifier's operation, purified water flows into the purified water storage chamber 2001 for storage through the first interface 2203a. In addition, when the water tank 2000 is detached from the main unit 1000, the first interface 2203a is closed to prevent the purified water in the water storage chamber 2001 from leaking from the first interface 2203a.

[0121] Combination Figure 5 and Figure 13 As shown, in some embodiments of this application, the water purifier may further include a first valve body 2410 and a second valve body 2420. The first valve body 2410 is mounted on a first interface 2203a. Thus, when the first valve body 2410 is in the open state, it connects the first interface 2203a, allowing purified water discharged from the filter outlet 5001 to flow into the purified water storage chamber 2001 for storage. When the first valve body 2410 is in the closed state, it closes the first interface 2203a, preventing purified water in the purified water storage chamber 2001 from leaking from the first interface 2203a.

[0122] For example, when the water tank 2000 is installed on the main unit 1000, the second interface 2203b is in a conductive state, so that the water storage chamber 2001 and the liquid level communication chamber 4100 together form a "communicating vessel structure"; when the water tank 2000 is detached from the main unit 1000, the second interface 2203b is in a closed state, thereby preventing the purified water in the water storage chamber 2001 from leaking from the second interface 2203b.

[0123] Combination Figure 2 and Figure 13 As shown in some embodiments of this application, the surface of the main unit 1000 that contacts the water tank 2000 is provided with two actuating valves 1001 that respectively abut against the first interface 2203a and the second interface 2203b. When the water tank 2000 is installed on the main unit 1000, the actuating valves 1001 abut against the first interface 2203a and the second interface 2203b. The first interface 2203a is opened and communicates with the filter outlet 5001 of the filter assembly 5000, and the second interface 2203b is opened and communicates with the liquid level communication chamber 4100. When the water tank 2000 leaves the main unit 1000, the actuating valves 1001 are separated from the first interface 2203a and the second interface 2203b, and both the first interface 2203a and the second interface 2203b are closed.

[0124] For example, in some embodiments of this application, a first interface 2203a is equipped with a first valve body 2410, and a second interface 2203b is equipped with a second valve body 2420. The first valve body 2410 may include a first valve bracket and a first valve core. The first valve core is movably mounted on the first valve bracket, and the first valve body 2410 is selectively activated by the movement of the first valve core relative to the first valve bracket. Similarly, the second valve body 2420 may include a second valve bracket and a second valve core. The second valve core is movably mounted on the second valve bracket, and the second valve body 2420 is selectively activated by the movement of the second valve core relative to the second valve bracket. More specifically, the first valve bracket is mounted on the first interface 2203a to achieve the effect of the first valve body 2410 being mounted on the first interface 2203a, and the second valve bracket is mounted on the second interface 2203b to achieve the effect of the second valve body 2420 being mounted on the second interface 2203b.

[0125] The two actuating valves 1001 installed on the main unit 1000 can be a first actuating valve and a second actuating valve, respectively. When the water tank 2000 is installed on the main unit 1000, the first actuating valve drives the first valve core to move, triggering the first valve body 2410 to open, and the second actuating valve drives the second valve core to move, triggering the second valve body 2420 to open. Thus, by setting the first actuating valve 1001 and the second actuating valve, when the water tank 2000 is installed on the main unit 1000, the first actuating valve triggers the first valve body 2410 to open, automatically connecting the first interface 2203a, and the first actuating valve triggers the second valve body 2420 to open, automatically connecting the second interface 2203b. When the water tank 2000 is detached from the main unit 1000, the first valve core is reset to achieve the effect of automatically closing the first interface 2203a due to the first actuation valve disengaging from the first valve core, and the second interface 2203b is automatically closed due to the second actuation valve disengaging from the second valve core.

[0126] It should be further explained that when the two actuating valves 1001 are in contact with the first valve body 2410 and the second valve body 2420 respectively, the actuating valves 1001 are in the open state; when the two actuating valves 1001 are separated from the first valve body 2410 and the second valve body 2420 respectively, the actuating valves 1001 are in the closed state. Therefore, when the actuating valve 1001 is in contact with the first valve body 2410, the actuating valve 1001 and the first valve body 2410 are in a connected state, and when the actuating valve 1001 is in contact with the second valve body 2420, the actuating valve 1001 and the second valve body 2420 are in a connected state. Thus, when the actuating valve 1001 is in the open state, the first valve body 2410 and the second valve body 2420 are connected to the pipeline located inside the main unit 1000.

[0127] Therefore, according to the water purifier of this application, two actuating valves 1001 are provided on the surface of the main unit 1000 that contacts the purified water tank 2000. When the purified water tank 2000 is installed on the main unit 1000, the two actuating valves 1001 respectively trigger the first interface 2203a and the second interface 2203b to be in the open state. The first interface 2203a is opened so that the purified water storage chamber 2001 is connected to the filter outlet 5001 through the first interface 2203a, so that the purified water discharged from the filter outlet 5001 can flow into the purified water storage chamber 2001 through the first interface 2203a. At the same time, since the first interface 2203a is in the conductive state, it also prevents the purified water in the purified water storage chamber 2001 from flowing back to the filter outlet 5001 through the first interface 2203a. The second interface 2203b is opened so that the liquid level communication cavity 4100 can communicate with the purified water storage cavity 2001 through the second interface 2203b, so that the purified water storage cavity 2001 and the liquid level communication cavity 4100 together constitute a "communicating vessel structure".

[0128] Preferably, the first actuating valve 1001 and the second actuating valve 1001 trigger the opening of the first interface 2203a and the second interface 2203b simultaneously, thereby connecting the purified water storage chamber 2001 with the filter outlet 5001 and the liquid level communication chamber 4100. When the purified water tank 2000 is detached from the main unit 1000, the two actuating valves 1001 disengage from the first interface 2203a and the second interface 2203b, respectively, so that both the first interface 2203a and the second interface 2203b are in a closed state. In this way, when the purified water tank 2000 is detached from the main unit 1000, leakage of purified water in the purified water storage chamber 2001 through the first interface 2203a and / or the second interface 2203b is prevented.

[0129] It should be further noted that in some of the above embodiments, two actuating valves 1001 are provided on the main unit 1000, and the two actuating valves 1001 respectively trigger the opening of the first interface 2203a and the second interface 2203b. Thus, when the purified water tank 2000 is installed on the main unit 1000, the first interface 2203a and the second interface 2203b automatically connect, allowing the purified water storage chamber 2001 to connect with the filter outlet 5001 and the liquid level communication chamber 4100. And when the purified water tank 2000 is detached from the main unit 1000, the first interface 2203a and the second interface 2203b automatically close to prevent purified water in the purified water storage chamber 2001 from leaking through the first interface 2203a and / or the second interface 2203b.

[0130] However, this application is not limited to this. For example, in some other embodiments of this application, the water purifier also includes a controller, a first sensor, and a second sensor. The first sensor is disposed on the surface of the main unit 1000 that contacts the water tank 2000, and the second sensor is disposed on the surface of the water tank 2000 that contacts the first sensor. When the water tank 2000 is installed on the main unit 1000, the first sensor and the second sensor contact each other to generate an "engagement signal." The controller generates an "opening command" based on the "engagement signal" to control the first valve body 2410 and the second valve body 2420 to open. Thus, when the water tank 2000 is installed on the main unit 1000, the water purifier can control the first valve body 2410 and the second valve body 2420 to open so that both the first interface 2203a and the second interface 2203b are in a conductive state, thereby connecting the purified water storage chamber 2001 with the filter outlet 5001 and the liquid level communication chamber 4100. When the water tank 2000 is detached from the main unit 1000, the first sensor and the second sensor separate, and the "engagement signal" disappears, causing the controller to generate a "closing command" to control the first valve body 2410 and the second valve body 2420 to close. Therefore, when the water tank 2000 is detached from the main unit 1000, the water purifier can control the first valve body 2410 and the second valve body 2420 to close, ensuring that both the first interface 2203a and the second interface 2203b are closed, thereby preventing the purified water in the purified water storage chamber 2001 from leaking through the first interface 2203a and / or the second interface 2203b.

[0131] See Figure 15 As shown, in some embodiments of this application, the liquid level monitor 4000 may include a connecting housing 410, within which a liquid level connecting cavity 4100 is provided. The connecting housing 410 also includes a liquid level connecting port 4002 and a liquid level vent 4001, both of which are connected to the liquid level connecting cavity 4100. Along the height direction of the water purifier, the liquid level vent 4001 is higher than the liquid level connecting port 4002. The liquid level connecting port 4002 is located at the bottom of the connecting housing 410 and is connected to the second interface 2203b. The liquid level vent 4001 allows the liquid level connecting cavity 4100 to communicate with the external environment.

[0132] For example, in combination Figure 15 Figure 19As shown, in some embodiments of this application, the liquid level vent 4001 connects the liquid level communication cavity 4100 to the external environment, allowing the liquid level communication cavity 4100 to maintain pressure balance with the external environment through the liquid level vent 4001. Thus, during the water purification process, the purified water in the purified water storage cavity 2001 flows to the liquid level communication port 4002 through the second interface 2203b. As the purified water flows into the liquid level communication cavity 4100 through the liquid level communication port 4002, the air inside the liquid level communication cavity 4100 can be discharged through the liquid level vent 4001, thereby avoiding liquid level monitoring errors caused by air resistance.

[0133] Furthermore, it should be noted that the clean liquid level connection port 4002, used for communicating with the second interface 2203b, is located at the bottom of the communicating housing 410. Thus, when the clean water tank 2000 is installed on the main unit base 1000, since the second interface 2203b communicates with the clean water storage chamber 2001, the clean water storage chamber 2001 and the liquid level connection chamber 4100 together constitute a "communicating vessel structure." This design ensures that the liquid level height of the clean water storage chamber 2001 and the liquid level connection chamber 4100 always follows the principle of communicating vessels, ensuring dynamic balance of the liquid levels in the clean water storage chamber 2001 and the liquid level connection chamber 4100. This allows the liquid level height within the liquid level connection chamber 4100 to accurately reflect the liquid level status of the clean water storage chamber 2001 in real time.

[0134] For example, see Figure 15 As shown, in some embodiments of this application, the connecting housing 410 may include a connecting cover and a connecting body. The connecting cover is detachably assembled to the connecting body so that a liquid level connecting cavity 4100 is formed within the connecting housing 410. A clean liquid level vent 4001 is disposed on the connecting cover, and a clean liquid level connecting port 4002 is disposed at the bottom of the connecting body. More specifically, a liquid level connecting groove is provided within the connecting body. When the connecting cover is assembled to the connecting body, the connecting cover covers the opening of the liquid level connecting groove, thereby defining the liquid level connecting cavity 4100. Furthermore, the clean liquid level connecting port 4002 disposed on the connecting body communicates with the liquid level connecting groove, thus achieving the effect of communication between the clean liquid level connecting port 4002 and the liquid level connecting cavity 4100. Also, when the connecting cover is assembled to the connecting body, the clean liquid level vent 4001 communicates with the liquid level connecting groove, thus achieving the effect of communication between the clean liquid level vent 4001 and the liquid level connecting cavity 4100.

[0135] Combination Figure 13 and Figure 15As shown, in some embodiments of this application, along the height direction of the water purifier, the clean liquid level connection port 4002 is higher than the second interface 2203b. It should be understood that since the clean liquid level connection port 4002 is located at the bottom of the connecting housing 410, and the second interface 2203b is located at the bottom of the purified water tank 2000, and the clean liquid level connection port 4002 and the second interface 2203b are at the same height, when the liquid level in the liquid level connection cavity 4100 drops to the bottom of the liquid level connection cavity 4100, it can also be understood as the moment when the liquid in the liquid level connection cavity 4100 is emptied, at which time a certain level of purified water is still retained in the purified water storage cavity 2001. Furthermore, since the liquid level sensor 4200 monitors the liquid level state in the liquid level connection cavity 4100 to monitor the liquid level state in the purified water storage cavity 2001, this allows the liquid level sensor 4200 to detect the moment when the liquid in the liquid level connection cavity 4100 is emptied, triggering the low liquid level protection mechanism of the water purifier.

[0136] For example, when the low-liquid-level protection mechanism of the water purifier is triggered, the water purifier continues to produce water until the liquid level in the purified water storage chamber 2001 reaches the preset maximum liquid level line. It is important to understand that because the bottom of the liquid level communication chamber 4100 is higher than the bottom of the purified water storage chamber 2001, there is a time difference between the time when the liquid in the liquid level communication chamber 4100 empties and the time when the liquid in the purified water storage chamber 2001 empties. This time difference serves as a buffer time for the water purifier. For example, the filter assembly 5000 can utilize this buffer time to increase the water production rate from zero liters to a constant water production rate.

[0137] In some embodiments of this application, the size of the clean liquid level connection port 4002 is S1, and the size of the clean liquid level vent port 4001 is S2, satisfying the relationship: S1≤S2. In other words, for the liquid level connection cavity 4100, the exhaust volume can be greater than or equal to the inlet volume. Thus, during the process of liquid entering the liquid level connection cavity 4100 from the clean liquid level connection port 4002, the air located in the liquid level connection cavity 4100 can be quickly discharged through the clean liquid level vent port 4001, avoiding the lag in liquid level rise caused by the increase in air pressure in the liquid level connection cavity 4100, thereby improving the accuracy of the clean liquid level monitor 4000 in monitoring the liquid level status of the clean water storage cavity 2001. Furthermore, during the process of liquid flowing from the liquid level communication cavity 4100 through the clean liquid level communication port 4002 to the second interface 2203b and then back to the clean water storage cavity 2001, external air can quickly replenish the liquid level communication cavity 4100, preventing the formation of negative pressure within the liquid level communication cavity 4100, which could lead to incomplete emptying or "siphon residue". Therefore, as the clean water storage cavity 2001 changes from a waterless state to a water-containing state, the liquid level difference between the liquid level communication cavity 4100 and the clean water storage cavity 2001 can quickly decrease to near zero. And after the liquid level difference between the liquid level communication cavity 4100 and the clean water storage cavity 2001 returns to zero, since the liquid level state of the liquid level communication cavity 4100 and the liquid level state of the clean water storage cavity 2001 are dynamically balanced in real time, the clean liquid level monitor 4000 can monitor the liquid level state of the clean water storage cavity 2001 in real time during the water storage process.

[0138] In some embodiments of this application, the aperture of the clean liquid level connection port 4002 is R1, and the aperture of the clean liquid level vent port 4001 is R2, satisfying the relationship: R1 = R2 = 5 mm. For example, in some embodiments of this application, both the clean liquid level connection port 4002 and the clean liquid level vent port 4001 are circular holes, and both have an aperture of five millimeters. It should be noted that the above example uses circular holes for both the clean liquid level connection port 4002 and the clean liquid level vent port 4001 as an example, but this application is not limited to this. For example, the configuration of the clean liquid level connection port 4002 and / or the clean liquid level vent port 4001 may be elliptical, a slit-type opening, or a multi-hole array, etc. It should be further explained that, according to the water purifier of this application, regardless of whether the water tank 2000 is locked or unlocked, the liquid level communication cavity 4100 can accurately indicate the liquid level of the water storage cavity 2001, and ensure that the water storage cavity 2001 is filled with more than 2 / 3 of its volume of purified water regardless of whether the water tank 2000 is locked or unlocked, and that there will be no overflow.

[0139] See Figure 15As shown, in some embodiments of this application, the net liquid level monitor 4000 may further include a float 4300, which is disposed within the liquid level communication cavity 4100. The float 4300 automatically floats up and down as the liquid level in the liquid level communication cavity 4100 changes. The liquid level sensor 4200 is used to sense and monitor the floating state of the float 4300, so as to monitor the liquid level in the liquid level communication cavity 4100 and the liquid level in the clean water storage cavity 2001 that forms a communication with the liquid level communication cavity 4100.

[0140] For example, in some embodiments of this application, since the clean liquid level connection port 4002 is connected to the bottom of the liquid level connection cavity 4100, as liquid flows into or out of the liquid level connection cavity 4100 through the clean liquid level connection port 4002, the liquid level in the liquid level connection cavity 4100 gradually rises or falls based on the bottom of the liquid level connection cavity 4100, thus stabilizing the liquid level change in the liquid level connection cavity 4100. Because the liquid level change in the liquid level connection cavity 4100 is stable, and the float 4300 automatically floats up and down with the liquid level change in the liquid level connection cavity 4100, the float 4300 floats stably, allowing the floating state of the float 4300 to accurately reflect the liquid level state in the liquid level connection cavity 4100. This enables the liquid level sensor 4200 to accurately sense and monitor the liquid level state in the liquid level connection cavity 4100, thereby achieving accurate sensing and monitoring of the liquid level state in the purified water storage cavity 2001 by the liquid level sensor 4200.

[0141] See Figure 15 As shown, in some embodiments of this application, the liquid level sensor 4200 includes at least one reed switch, and the magnetic trigger of the float 4300 is configured to trigger the reed switch. For example, in some embodiments of this application, the liquid level sensor 4200 is provided with one reed switch. Since the water purification storage chamber 2001 and the liquid level communication chamber 4100 together form a "communicating vessel structure," the liquid level heights of the water purification storage chamber 2001 and the liquid level communication chamber 4100 are always dynamically consistent. Furthermore, in the height direction of the water purifier, the installation position of the reed switch can be set according to the target liquid level threshold of the water purification storage chamber 2001 (such as a low water level alarm point or a full water level stop point). For example, when the liquid level in the water purification storage chamber 2001 reaches a preset height, the liquid level in the liquid level communication chamber 4100 synchronously reaches the corresponding height, driving the float 4300 to rise or fall with the liquid level, causing the magnetic trigger embedded in the float 4300 to move precisely to a position horizontally aligned with the reed switch. At this time, the magnetic field generated by the magnetic trigger acts on the reed of the reed switch, causing it to be magnetized and attract each other to close (or repel each other to open), thereby enabling the liquid level sensor 4200 to output a signal to realize real-time feedback on the liquid level status of the water storage chamber 2001.

[0142] More specifically, taking the monitoring of the highest liquid level in the water purification storage chamber 2001 as an example: the reed switch is fixed outside the liquid level communication chamber 4100, and the height of the reed switch in the water purifier is level with the rated maximum liquid level height of the water purification storage chamber 2001. When the water purification storage chamber 2001 is filled to full, the liquid level in the liquid level communication chamber 4100 rises synchronously, and the float 4300 floats up under the action of buoyancy until the magnetic trigger body and the reed switch are at the same horizontal plane. At this moment, the magnetic trigger body triggers the reed switch to act. Thus, when the liquid level in the water purification storage chamber 2001 reaches the maximum liquid level height, the liquid level sensor 4200 outputs a signal to provide real-time feedback on the liquid level status of the water purification storage chamber 2001.

[0143] Similarly, the installation height of the reed switch can be aligned with the minimum safe liquid level of the purified water storage chamber 2001. When the purified water storage chamber 2001 descends to this height, the float 4300 drives the magnetic trigger to descend until the magnetic trigger is at the same level as the reed switch. At this moment, the magnetic trigger triggers the reed switch to operate. Thus, when the liquid level in the purified water storage chamber 2001 reaches the minimum safe liquid level, the liquid level sensor 4200 outputs a signal to provide real-time feedback on the liquid level status of the purified water storage chamber 2001.

[0144] It should be further explained that, in the above embodiments, taking the liquid level sensor 4200 with one reed switch as an example, the installation height of the reed switch in the height direction of the water purifier is level with the rated maximum liquid level height of the purified water storage chamber 2001, or the installation height of the reed switch is level with the minimum safe liquid level height of the purified water storage chamber 2001. However, this application is not limited to this; the liquid level sensor 4200 can be provided with multiple reed switches, and different reed switches are located at different height positions in the height direction of the water purifier. For example, in some embodiments of this application, the liquid level sensor 4200 is provided with two reed switches, and in the height direction of the water purifier, the installation height of one reed switch is level with the rated maximum liquid level height of the purified water storage chamber 2001, and the installation height of the other reed switch is level with the minimum safe liquid level height of the purified water storage chamber 2001.

[0145] See Figure 13As shown in some embodiments of this application, the water purifier may further include a raw water tank 3000, which has a raw water storage chamber 3001 for temporarily storing raw water (such as tap water, groundwater, etc.) to be filtered. The raw water storage chamber 3001 is connected to the filter inlet 5003 of the filter assembly 5000, so that the raw water stored in the raw water storage chamber 3001 can enter the filter assembly 5000 through the filter inlet 5003. The raw water is filtered by the filter assembly 5000 to produce purified water. The purified water flows from the filter outlet 5001 of the filter assembly 5000 into the purified water storage chamber 2001 of the purified water tank 2000, so that the purified water storage chamber 2001 is used to temporarily store the purified water produced by the filter assembly 5000.

[0146] For example, in some embodiments of this application, the raw water tank 3000 adopts a detachable structural design to improve user operation convenience. For instance, the raw water tank 3000 is detachably installed in a pre-set assembly slot of the main unit 1000 via a slide rail buckle or magnetic attraction mechanism, and its bottom is provided with a water outlet interface communicating with the raw water storage chamber 3001. When the raw water tank 3000 is installed on the main unit 1000, the water outlet interface and the filter inlet 5003 of the filter assembly 5000 are automatically connected through a quick connector to form a continuous water supply path. Raw water flows into the filter assembly 5000 through the filter inlet 5003 under gravity or pump drive. When the raw water tank 3000 is removed from the main unit 1000, the elastic valve core in the quick connector is reset by the action of the internal spring, simultaneously closing the water outlet interface of the raw water tank 3000 and the filter inlet 5003 of the filter assembly 5000, realizing instantaneous disconnection of the water path and preventing raw water leakage.

[0147] See Figures 16 to 19 As shown, in some embodiments of this application, the water purifier may further include a first pump body 6000, which is connected between the raw water storage chamber 3001 and the filter inlet 5003. The first pump body 6000 is configured to pump the raw water in the raw water storage chamber 3001 to the filter assembly 5000. Under the pumping action of the first pump body 6000, the raw water flowing into the filter assembly 5000 from the raw water storage chamber 3001 has a certain pressure, causing the liquid to flow from the filter inlet 5003 to the filter outlet 5001 at a certain flow rate.

[0148] For example, the first pump 6000 is configured to operate in conjunction with the purified water level monitor 4000, causing the first pump 6000 to start operating based on the water level in the purified water storage chamber 2001. For instance, when the purified water level monitor 4000 detects that the water level in the purified water storage chamber 2001 is below a preset minimum threshold, the first pump 6000 is set to start operating at maximum power to accelerate the water production rate of the filter assembly 5000, thereby quickly replenishing the purified water in the purified water storage chamber 2001. As the water level in the purified water storage chamber 2001 gradually rises, the power of the first pump 6000 can be set to gradually decrease, matching the water production flow rate with the volume increase of the purified water storage chamber 2001, avoiding the risk of overflow due to a rapid rise in water level. When the water level reaches the full water level threshold, the first pump 6000 is set to shut down to terminate the water production process.

[0149] See Figure 17 and Figure 19 As shown, in some embodiments of this application, the water purifier may further include a flushing valve 7000, a filter assembly 5000 having a flushing port 5002, a first valve port of the flushing valve 7000 communicating with the flushing port 5002, and a second valve port of the flushing valve 7000 communicating with the external environment and / or the raw water storage chamber 3001. Exemplarily, when the flushing valve 7000 is open, the first valve port and the second valve port are in a conductive state; when the flushing valve 7000 is closed, the first valve port and the second valve port are not in a conductive state. For example, when the flushing valve 7000 is open, the first pump body 6000 drives liquid to flow from the filter inlet 5003 to the flushing valve 7000, and cleans the filter assembly 5000 by discharging the liquid through it. Furthermore, since the second valve port is connected to the external environment and / or the raw water storage chamber 3001, the liquid discharged from the second valve port can be discharged into the environment and / or the raw water storage chamber 3001. If the second valve port is connected to the external environment, the high-pressure liquid is discharged through the flushing port 5002 and carries the pollutants intercepted on the surface of the filter element directly to the outside; if the second valve port is connected to the raw water storage chamber 3001, the flushing water is injected back into the raw water tank 3000, and the impurities are collected and centrally cleaned by circulating and flushing the coarse filter element 3200.

[0150] See Figure 17 and Figure 19As shown, in some embodiments of this application, the raw water tank 3000 may include a raw water tank body 3100 and a coarse filter element 3200. The raw water tank body 3100 contains a raw water storage chamber 3001 and is also provided with a third interface 3110 and a fourth interface 3120. Both the third interface 3110 and the fourth interface 3120 are connected to the raw water storage chamber 3001, and the third interface 3110 is also connected to the filter inlet 5003, thus setting the third interface 3110 as a water supply port connecting the raw water storage chamber 3001 and the filter inlet 5003. The fourth interface 3120 is also connected to a second valve port, allowing the fourth interface 3120 to indirectly connect to the flushing port 5002 of the filter element 5000 via the second valve port of the flushing valve 7000, forming a flushing circuit so that the liquid discharged from the flushing of the filter element 5000 flows back into the raw water storage chamber 3001 through the fourth interface 3120. The coarse filter element 3200 is assembled in the raw water storage chamber 3001. The coarse filter element 3200 is configured to filter the raw water discharged from the raw water storage chamber 3001 through the third interface 3110, so that the raw water in the raw water storage chamber 3001 is pre-filtered by the coarse filter element 3200 and then pumped to the filter assembly 5000 through the third interface 3110 for deep purification.

[0151] See Figure 18 and Figure 19 As shown, in some embodiments of this application, the water purifier may further include a heating element 8000 connected to the filter outlet 5001 and a water outlet 1100 connected to the heating element 8000. Water in the filter outlet 5001 is heated by the heating element 8000 and then flows out to the outside through the water outlet 1100. For example, in some embodiments of this application, the heating element 8000 is connected in series downstream of the filter outlet 5001 of the filter assembly 5000. The inlet end of the heating element 8000 is connected to the filter outlet 5001, and the outlet end of the heating element 8000 is connected to the water outlet 1100. This allows purified water discharged from the filter assembly 5000 to be heated by the heating element 8000 and then flow into the water outlet 1100, thereby providing the user with clean hot water.

[0152] See Figure 18 and Figure 19 As shown, in some embodiments of this application, the water purifier may further include a water outlet 1100, which is connected to a filter outlet 5001 and a first interface 2203a. The water outlet 1100 receives purified water directly filtered by the filter assembly 5000 via the filter outlet 5001 and purified water from the purified water tank 2000 and the purified water level monitor 4000 via the first interface 2203a, and provides this water to the user. This ensures that the purified water level monitor 4000 can accurately indicate the water level in the purified water tank when the user takes water.

[0153] Further, see Figure 18 and Figure 19 As shown, in some embodiments of this application, the water purifier also includes a heating element 8000, one end of which is connected to the filter outlet 5001 and the first interface 2203a, and the other end of which is connected to the water outlet 1100, so that the user can obtain clean hot water.

[0154] See Figure 18 and Figure 19 As shown, in some embodiments of this application, the water purifier may further include a second pump body 9000, which is connected between the filter outlet 5001 and the water outlet 1100. The second pump body 9000 is configured to pump water filtered by the filter assembly 5000 to the water outlet 1100. The second pump body 9000 overcomes the pipeline resistance from the filter outlet 5001 to the water outlet 1100, ensuring a stable high-flow-rate water supply.

[0155] Combination Figure 2 As shown, in some embodiments of this application, a UV lamp 1200 is provided at the contact point between the main unit 1000 and the purified water tank 2000. At least a portion of the purified water tank 2000 is made of a transparent material to facilitate observation of the UV lamp 1200's status. Exemplarily, in some embodiments of this application, the UV lamp 1200 is embedded in the assembly contact surface between the main unit 1000 and the purified water tank 2000, and at least a portion of the purified water tank 2000 is made of a high-transmittance material (such as transparent ABS or polycarbonate). When the purified water tank 2000 is installed on the main unit 1000, the UV lamp 1200 faces the bottom of the purified water tank 2000, and its radiation range covers at least a portion of the purified water storage cavity 2001, achieving continuous ultraviolet sterilization of the stored purified water. Simultaneously, the transparent area of ​​the purified water tank 2000 allows users to directly observe the working status of the UV lamp 1200 (such as light color and flashing frequency) and the liquid level changes within the purified water storage cavity 2001, combining functional and visual monitoring values.

[0156] Combination Figure 2 and Figure 5As shown, in some embodiments of this application, an actuating part 2500 is provided on the outer surface of the water purification tank 2000, and a micro switch 1300 is provided at the contact point between the main unit 1000 and the water purification tank 2000. When the actuating part 2500 abuts against the micro switch 1300, the UV lamp 1200 is in the lit state; when the actuating part 2500 moves away from the micro switch 1300, the UV lamp 1200 is in the off state. Exemplarily, in some embodiments of this application, when the water purification tank 2000 is installed on the main unit 1000, the actuating part 2500 triggers the micro switch 1300, turning on the circuit of the UV lamp 1200 and putting it into operation; when the water purification tank 2000 is disassembled or not fully installed, the actuating part 2500 and the micro switch 1300 are separated, and the circuit of the UV lamp 1200 is not turned on, ensuring zero risk of ultraviolet leakage.

[0157] See Figure 1 and Figure 2 As shown, this application provides a water purifier, which includes a main unit base 1000 and a purified water tank 2000, the purified water tank 2000 being detachably mounted on the main unit base 1000. (See reference...) Figure 3 and Figure 4 As shown, the purified water tank 2000 includes a matching tank body 2100 and a tank lid 2200. The tank body 2100 and the tank lid 2200 can be selectively sealed according to usage requirements. That is, when the tank body 2100 is assembled (closed) relative to the tank lid 2200, the purified water tank 2000 is in a sealed closed state. When the tank body 2100 is separated (opened) relative to the tank lid 2200, the purified water tank 2000 is in an unsealed open state. The degree of sealing and specific sealing methods between the tank body 2100 and the tank lid 2200 can be set according to sealing requirements when in the closed state to meet diverse user needs. Those skilled in the art can set these settings according to actual needs, and no limitations are made here.

[0158] Water tank 2100 is equipped with a purified water storage chamber 2001. (See also...) Figures 6 to 12 As shown, the purified water tank 2000 has an outlet 2201 and at least one flow control port 2202, which can be provided on at least one of the tank body 2100 and the tank cover 2200 as needed. For example, the outlet 2201 and at least one flow control port 2202 can be provided on the tank cover 2200, and the outlet 2201 is configured to allow liquid to flow out of the purified water storage chamber 2001, which can be water, especially filtered purified water.

[0159] The aforementioned water purification tank 2000 can be configured to have two states, which can be set to a locked state and an unlocked state, respectively. When the water purification tank 2000 is in the locked state, the outlet 2201 is sealed, and the outlet 2201 cannot be used to allow liquid in the water purification storage chamber 2001 to flow out. When the water purification tank 2000 is in the unlocked state, the liquid in the water purification storage chamber 2001 can flow to the outside through the outlet 2201. Therefore, when a user needs to use purified water, they can change the locked state of the water purification tank 2000 to the unlocked state, thereby pouring out the purified water from the water purification tank 2000 through the outlet 2201.

[0160] The flow control port 2202 differs from the outlet 2201 in that its opening area is smaller than that of the outlet 2201. For example, if both the flow control port 2202 and the outlet 2201 are circular holes, their opening areas can be compared based on the hole diameter. Otherwise, if the flow control port 2202 and the outlet 2201 have other regular or irregular shapes, their opening areas need to be calculated based on the specific shape. The one or more flow control ports 2202 can be configured to always maintain communication between the gas inside the purified water storage chamber 2001 and the external atmospheric pressure. However, due to the special design of the opening area of ​​the flow control port 2202, it is necessary for the flow control port 2202 to maintain the following capability: when the purified water tank 2000 is locked and in an inverted or horizontal position, the liquid inside the purified water storage chamber 2001 cannot flow through the flow control port 2202 to the outside in a streamlined shape.

[0161] In short, the flow control port 2202 is a through-hole that always connects the purified water storage chamber 2001 to the outside. Based on the special design of the opening area of ​​the flow control port 2202, its flow control capability allows for the flow of gas between the inside and outside, while simultaneously preventing purified water from continuously spilling out of the water tank 2000 when it is inverted or placed horizontally. Preventing spillage can be understood as completely prohibiting spillage or allowing only a very small amount of purified water to spill out, thus satisfying users' habit of storing the water tank 2000 in an inverted or horizontal position in a refrigerator or other location.

[0162] Regarding the special design of the opening area of ​​the aforementioned flow control port 2202, in one embodiment, if the flow control port 2202 is configured as a circular hole, then the diameter of the flow control port 2202 can be limited to between 0.36mm and 0.7mm. For example, in one embodiment, the diameter of the flow control port 2202 can be set to 0.36mm, 0.4mm, 0.5mm, 0.7mm, etc. In addition, the flow control port 2202 can also be configured as a regular hole type such as a square hole or an elliptical hole, or other irregular hole types. When the flow control port 2202 is configured as other hole types, its maximum hole diameter value can also be set between 0.36mm and 0.7mm. The opening area can be calculated specifically based on different hole type designs, and no limitation is made here.

[0163] Taking the flow control port 2202 as an example of a circular hole, according to the experiment, when the diameter of the flow control port 2202 is set to 0.7mm, the inverted water tank 2000 can achieve no water droplet outflow, when the water tank 2000 is slowly turned over, a drop of water can be found to flow out every 5 seconds or so, when the water tank 2000 is quickly turned over, water droplets can be found to splash, and when the water tank 2000 is shaken, water droplets can be found to splash.

[0164] When the orifice diameter of the flow control port 2202 is set to 0.5mm, the water purification tank 2000 can achieve no water droplet out when inverted, no water droplet out when slowly flipped, water droplet splashing can be observed when quickly flipped, and water droplet splashing can be observed when shaking the water purification tank 2000.

[0165] When the orifice diameter of the flow control port 2202 is set to 0.4mm, the water purification tank 2000 can achieve no water droplet out when inverted, no water droplet out when slowly flipped, water droplet splashing can be observed when quickly flipped, and water droplet splashing can be observed when shaking the water purification tank 2000.

[0166] When the orifice diameter of the flow control port 2202 is set to 0.36mm, the water purification tank 2000 can achieve no water droplet out when inverted, no water droplet out when slowly flipped, no water droplet splashing when quickly flipped, and water droplet splashing can be observed when the water purification tank 2000 is shaken.

[0167] In the above experiment, the liquid becomes unstable when the water tank 2000 is inverted, resulting in an impact force as the liquid flows through the flow control port 2202. Therefore, the orifice diameter of the flow control port 2202 should be set as small as possible. However, in actual production, a smaller orifice diameter of the flow control port 2202 increases production difficulty, and a smaller orifice diameter also results in poorer gas permeability between the water tank 2000 and the outside environment.

[0168] When the main unit 1000 supplies water to the water tank 2000, if the orifice diameter of the flow control port 2202 is too small, it will affect the exhaust speed, and thus affect the speed at which water is supplied to the water tank 2000 through the first interface 2203a. Furthermore, when the water tank 2000 supplies water to the outlet 1100 on the main unit 1000, it will also affect the air intake speed, and thus affect the speed at which water is supplied to the outlet 1100 through the first interface 2203a on the water tank 2000. Therefore, based on the above data, the orifice diameter of the flow control port 2202 can be selected as 0.5mm, and the orifice diameter of the flow control port 2202 should be set as large as possible while meeting the requirements. Those skilled in the art can adjust the orifice diameter of the flow control port 2202 according to actual needs, and this is not limited here.

[0169] Furthermore, the flow control port 2202 can be a fixed-diameter or variable-diameter port. For example, the flow control port 2202 can have different diameters at different locations. In one embodiment, when the flow control port 2202 is located on the water tank cover 2200, the maximum diameter of the flow control port 2202 can be located inside the cover body of the water tank cover 2200, and the minimum diameter of the flow control port 2202 can be located outside the cover body of the water tank cover 2200. In the depth direction of the flow control port 2202, the diameter of the flow control port 2202 can vary in various ways, such as gradually changing or stepping, and is not limited here.

[0170] Therefore, after the user installs the water purification tank 2000 onto the main unit 1000, the flow control port 2202 ensures that the gas inside the water purification storage chamber 2001 is always connected to the external atmospheric pressure. This guarantees that the water flowing from the raw water tank 3000 or other water supply sources into the water purification storage chamber 2001 can also enter normally, preventing situations where excessive air pressure in the water purification tank 2000 prevents liquid from entering. Furthermore, after the user removes the water purification tank 2000 from the main unit 1000, the flow control port 2202 prevents the liquid in the water purification storage chamber 2001 from flowing through it to the outside in a streamlined shape. Therefore, regardless of whether the user places the water purification tank 2000 upside down or horizontally, spillage of purified water can be avoided.

[0171] Furthermore, no user intervention is required during this process; both of the aforementioned effects rely on the special design of the opening area of ​​the flow control port 2202. The opening design of the flow control port 2202 has a low cost, thus eliminating the need for specialized control mechanisms to achieve the aforementioned technical effects. This design avoids situations where users forget to unlock the water purifier tank 2000 after locking it, and directly install it onto the main unit 1000, resulting in the inability to produce or dispense water, which could lead users to mistakenly believe the machine is malfunctioning, thereby improving the user experience.

[0172] In one embodiment, the top of the main unit 1000 may have a top surface, and the top of the water tank 2000 may have a top surface. When the water tank 2000 is mounted on the main unit 1000, the top surface of the water tank 2000 is configured to be in the same plane as the top surface of the main unit 1000. Since the water tank 2000 and the main unit 1000 need to be aligned during assembly, it is not suitable to install a dedicated control mechanism on the water tank 2000, as this would affect the alignment of the water tank 2000 and the main unit 1000 during assembly. The above design ensures the aesthetics and compactness of the entire unit.

[0173] Continue reading Figure 5 As shown, the water purification tank 2000 is provided with a first interface 2203a and a second interface 2203b. Liquid can be designed to enter the water purification tank 2000 through the first interface 2203a, and liquid inside the water purification tank 2000 can also flow out through the first interface 2203a. Therefore, the first interface 2203a and the second interface 2203b can be used to achieve bidirectional flow of liquid between the inside and outside of the water purification tank 2000. For example, liquid can enter the water purification tank 2000 through the first interface 2203a, and liquid inside the water purification tank 2000 can flow out through the second interface 2203b. When the water purification tank 2000 is separated from the main unit 1000, both the first interface 2203a and the second interface 2203b must be kept in a sealed state to prevent liquid from spilling from the water purification tank 2000.

[0174] The water purifier may also include a fluid actuator, which is disposed on the main unit 1000 and configured to drive liquid from the water supply source into the purified water tank 2000. The water purifier may also include a raw water tank 3000, which is disposed on the main unit 1000. The raw water tank 3000 has a raw water chamber for holding unpurified water such as tap water. The raw water tank 3000 can serve as a water supply source, and the water in the raw water tank 3000 can be supplied to the purified water tank 2000. The supplied water is filtered by a filter assembly and stored in the purified water storage chamber 2001 of the purified water tank 2000. The fluid actuator may be configured to drive liquid from the raw water tank 3000 into the purified water tank 2000.

[0175] In one embodiment, a switch mounting groove 2230 may be provided on the outer surface of the water tank cover 2200, the switch mounting groove 2230 being configured for movably mounting a locking switch 2240. The locking switch 2240 may be configured to seal or expose the outlet 2201 of the water tank cover 2200.

[0176] For example, see Figure 7As shown, a locking push button 2242 can be installed on the locking switch 2240. (See reference...) Figure 7 As shown in the diagram, the user can push the locking push button 2242 on the locking switch 2240 to the right, and the locking push button 2242 will insert as shown. Figure 9 In the locking part 2243 shown, the locking switch 2240 is locked relative to the switch mounting groove 2230 and cannot move. Thus, the locking switch 2240 seals the outlet 2201 of the water tank cover 2200, so that the clean water tank 2000 is in a locked state.

[0177] Correspondingly, the user can push the locking push button 2242 on the locking switch 2240 to the left, and the locking push button 2242 will move from the left to the right. Figure 9 The locking part 2243 is disengaged, so that the locking switch 2240 is unlocked relative to the switch mounting slot 2230 and can move relative to the switch mounting slot 2230. Then, if the user presses the end of the locking switch 2240 away from the outlet 2201, the end of the locking switch 2240 near the outlet 2201 will be lifted up, thereby exposing the outlet 2201 of the water tank cover 2200 based on the lifting up, so that the water tank 2000 is in the unlocked state.

[0178] Therefore, when the locking switch 2240 seals the outlet 2201 of the water tank cover 2200, the purified water tank 2000 is locked, and the outlet 2201 cannot be used to allow liquid in the purified water storage chamber 2001 to flow out. When the purified water tank 2000 is unlocked and the locking switch 2240 exposes the outlet 2201 of the water tank cover 2200, the liquid in the purified water storage chamber 2001 can flow to the outside through the outlet 2201.

[0179] Therefore, when a user needs to use purified water, the locking switch 2240 can be used to change the locked state of the water tank 2000 to the unlocked state, exposing the outlet 2201 of the water tank cover 2200, and the purified water in the water tank 2000 can be poured out and used through the outlet 2201.

[0180] See Figure 4 and Figure 9As shown, at least one flow control port 2202 can be located within the aforementioned switch assembly slot 2230. When the locking switch 2240 is assembled with the switch assembly slot 2230, there can be a gap 2241 between them. This gap 2241 allows the flow control port 2202 to maintain communication between the gas in the purified water storage chamber 2001 and the external atmospheric pressure. Therefore, when the locking switch 2240 is assembled inside the switch assembly slot 2230, the locking switch 2240 can fill the switch assembly slot 2230, thus shielding the switch assembly slot 2230 and the flow control port 2202. This prevents dust and other contaminants from clogging the flow control port 2202, which is already relatively small in size, and thus prevents it from becoming ineffective due to dust or other blockages.

[0181] Continue reading Figure 9 As shown, in one embodiment, a switch mounting portion 2231 is provided within the switch mounting slot 2230, and the switch mounting portion 2231 is configured for movably mounting the locking switch 2240. This switch mounting portion 2231 can be designed to match the structure of the locking switch 2240, thereby achieving the movable mounting of the locking switch 2240 within the switch mounting slot 2230, and achieving the technical effect of sealing or exposing the outlet 2201 of the water tank cover 2200. Those skilled in the art can design according to actual needs, and no limitations are imposed here.

[0182] See Figure 9 As shown, in one embodiment of the switch mounting portion 2231, the switch mounting portion 2231 can enclose a shielding space 2232 within the slot of the switch mounting groove 2230, thus allowing at least one flow control port 2202 to be located within the shielding space 2232 of the switch mounting groove 2230. Since the switch mounting portion 2231 utilizes the shielding space 2232 to create a certain degree of circumferential shielding around the flow control port 2202, a certain degree of water-blocking effect can be achieved around the flow control port 2202. If liquid is accidentally spilled into the flow control port 2202, the shielding space 2232 can be used to prevent further spillage.

[0183] Regarding the matching of the flow control port 2202, the flow outlet 2201, and the gap 2241, when the water tank is in a horizontal position, the flow control port 2202 and the flow outlet 2201 can be designed to lie in a plane parallel to the horizontal plane in the horizontal position. (See further...) Figure 9 As shown, in one embodiment, if the water tank 2000 is placed horizontally with its side facing outward, the flow control port 2202 and the outlet 2201 can be arranged along the liquid outflow direction of the outlet.

[0184] When the water tank 2000 is in the locked state, a gap 2241 is formed between the locking switch 2240 and the switch mounting groove 2230, and the locking switch 2240 seals the outlet 2201. When the water tank 2000 is in the unlocked state, the gap 2241 between the locking switch 2240 and the switch mounting groove 2230 increases, allowing the liquid in the water tank 2000 to flow to the outside through the outlet 2201 and part of the gap 2241. During this process, the locking switch 2240 can always cover the flow control port 2202 to prevent dust and other substances from clogging the flow control port 2202.

[0185] In addition, the water tank cover 2200 may not have the switch mounting slot 2230, but instead directly mount the locking switch 2240. Therefore, in one embodiment, the locking switch 2240 may be provided on the outer surface of the water tank cover 2200, and the locking switch 2240 may be configured to seal or expose the outflow outlet 2201 of the water tank cover 2200. In one embodiment, at least one flow control port 2202 is located below the locking switch 2240, and a gap 2241 is always maintained between the locking switch 2240 and the water tank cover 2200, so that the flow control port 2202 maintains communication between the air in the purified water storage chamber 2001 and the external atmospheric pressure through the gap 2241.

[0186] At this point, the function and effect of the locking switch 2240 are the same as described above, and therefore will not be repeated. Any technical details regarding the locking switch 2240 can be found in the preceding description. Those skilled in the art can choose the structural design of the water tank cover 2200 according to actual needs, and no limitations are imposed here.

[0187] Continue reading Figures 7 to 12 As shown, in one embodiment, the water tank cover 2200 may include an outer cover 2210 and an inner cover 2220. In this case, the flow control port 2202 may be located on the outer cover 2210, and the inner cover 2220 is fitted inside the outer cover 2210. The inner cover 2220 has at least one interface 2204 configured to communicate with the flow control port 2202. Depending on the design of the flow control port 2202's aperture shape and size, the interface 2204 may be designed to match the flow control port 2202. For example, the interface 2204 may be configured as a circular aperture. Furthermore, the aperture of the interface 2204 may be larger than the aperture of the flow control port 2202, thereby ensuring that the interface 2204 can adequately cover the flow control port 2202. Moreover, the larger aperture design also reduces the manufacturing difficulty of the interface 2204.

[0188] Since the water tank cover 2200 can be assembled from an outer cover 2210 and an inner cover 2220, in one embodiment, the outlet 2201 may also include a cooperating first unit outlet 2201 and a second unit outlet 2201. The first unit outlet 2201 is located in the first unit region 2211 of the outer cover 2210, and the second unit outlet 2201 is located in the second unit region 2221 of the inner cover 2220. After the outer cover 2210 and the inner cover 2220 are assembled, the first unit outlet 2201 and the second unit outlet 2201 can be connected to form the aforementioned outlet 2201. In one embodiment, the outer cover 2210 and the inner cover 2220 can be connected by welding, adhesive bonding, or other methods.

[0189] Continue reading Figure 10 and Figure 11 As shown, in one embodiment, the inner surface of the outer cover 2210 may be provided with a first unit region 2211, and the flow control port 2202 is located within the first unit region 2211. The outer surface of the inner cover 2220 may be provided with a second unit region 2221, and the interface 2204 is located within the second unit region 2221. When the outer cover 2210 and the inner cover 2220 are assembled together, the edges of the first unit region 2211 and the second unit region 2221 can be sealed together, thereby forming a sealed space between the first unit region 2211 of the outer cover 2210 and the second unit region 2221 of the inner cover 2220. At this time, the flow control port 2202 and the interface 2204 can communicate with each other within the sealed space, and the sealed space can prevent liquid from flowing out.

[0190] Regarding the sealing connection between the edge of the first unit region 2211 and the edge of the second unit region 2221, for example, the edge of the first unit region 2211 and the edge of the second unit region 2221 can be sealed by welding, adhesive bonding, or other methods.

[0191] To improve the sealing effect, at least a portion between the edge of the first unit region 2211 and the edge of the second unit region 2221 may also be provided with a first sealing ring 2212. In this case, ultrasonic welding can be used, forming a first sealing area. If problems arise with the ultrasonic welding, the first sealing ring 2212 can further enhance the sealing effect, forming a second sealing area.

[0192] It should be noted that, for reference Figure 10 and Figure 11As shown, the edge of the first unit region 2211 is the area enclosed by the edges indicated by the two arrows labeled 2211, and the edge of the second unit region 2221 is the area enclosed by the edges indicated by the two arrows labeled 2221. Therefore, the area indicated by the two arrows labeled 2211 and the two arrows labeled 2221 constitutes the first sealing region.

[0193] The first sealing region and the second sealing region mentioned above may be the same or different. For example, when the first sealing region and the second sealing region are the same, after the edges of the first unit region 2211 and the edges of the second unit region 2221 are ultrasonically welded, a first sealing ring 2212 can be further set to improve the sealing effect.

[0194] Alternatively, when the first sealing region and the second sealing region are different, after the edge of the first unit region 2211 and the edge of the second unit region 2221 are ultrasonically welded, a second sealing region can be further constructed around the first sealing region. That is, at this time, the first sealing ring 2212 can be used to construct a second sealing region around the first region defined above.

[0195] For example, see Figure 10 As shown, the area indicated by the two arrows labeled 2212 is the second sealing area. The edge of this second sealing area may partially overlap with the edge of the first sealing area, or it may be completely located outside the first sealing area without any overlap; this is not limited.

[0196] In one embodiment, the first unit region 2211 may be configured as a region groove formed on the inner surface of the outer cover 2210, and the second unit region 2221 may be configured as a region groove formed on the outer surface of the inner cover 2220. Therefore, as long as at least one of the first unit region 2211 and the second unit region 2221 is provided with a region groove, the sealing space can have sufficient spatial height, which facilitates the design and manufacture of the internal structures.

[0197] Continue reading Figure 4 and Figure 6As shown, in one embodiment, the water purifier may further include a lid support 2300, which is disposed at the water cavity opening of the water tank body 2100 and is used to cooperate with the water tank lid 2200 to selectively seal the water cavity opening. The lid support 2300 has a downwardly extending mating wall 2310, which is configured to cooperate with the water tank lid 2200. The mating wall 2310 of the lid support 2300 is provided with a drainage notch 2301, and the water tank lid 2200 is provided with a drainage port 2302 that cooperates with the drainage notch 2301 to drain water. The drainage port 2302 is configured to communicate with the outlet 2201.

[0198] Therefore, the water tank cover 2200 can be indirectly fitted to the water cavity opening of the water tank body 2100 via the cover bracket 2300. Liquid in the water tank body 2100 can be centrally drained through the drainage notch 2301 of the cover bracket 2300, then flows to the drainage port 2302 of the water tank cover 2200, and finally flows through the drainage port 2302 to the outlet 2201, exiting the purified water tank 2000 for user use, thus preventing residual water in the purified water tank 2000 from being unable to be poured out. In one embodiment, the cover bracket 2300 and the water cavity opening of the water tank body 2100 can be assembled using various methods such as welding, bonding, and snap-fit. Furthermore, to improve the sealing effect, at least one of the cover bracket 2300 and the water tank cover 2200 can be provided with a second sealing ring 2320.

[0199] The water purification tank 2000 can be designed in the shape of a cube, cuboid, or other polyhedron as needed. Therefore, in one embodiment, the side wall of the water purification tank 2000 may have at least one planar resting area. This planar resting area can be one of the side walls of the water purification tank 2000, or one planar region of the side wall. The function of this planar resting area is to rest the water purification tank 2000. That is, when the water purification tank 2000 is placed in a horizontal position, the planar resting area can be parallel to the resting surface to maintain the current placement angle or state of the water purification tank 2000.

[0200] Regarding the number of flow control ports 2202, one, two, or more flow control ports 2202 can be set. Those skilled in the art can set this according to actual needs, and no limitation is made here. For example, if the number of flow control ports 2202 is limited to at least two, then all flow control ports 2202 can be placed within a common virtual plane, and this common virtual plane is parallel to the aforementioned planar placement area. Since the water tank 2000 is primarily placed horizontally, if there is a height difference between two or more flow control ports 2202, the water level may be in the middle of adjacent flow control ports 2202, causing the internal air to be connected to the outside atmosphere. In this case, air will enter through the upper flow control port 2202, and water will exit through the lower flow control port 2202, easily leading to unexpected water leakage. Therefore, it is necessary to keep all flow control ports 2202 on the same horizontal plane.

[0201] For example, when the number of flow control ports 2202 is set to one, that single flow control port 2202 can be set as follows: Figure 9 The switch assembly slot 2230 shown is within the shielding space 2232. In this case, the advantage of having only one flow control port 2202 is that it avoids the situation mentioned above where one flow control port 2202 is for air intake and another for water output, preventing unexpected water outflow. Furthermore, since the single flow control port 2202 within the shielding space 2232 is far from the outlet 2201, and the shielding space 2232 provides a certain degree of circumferential shielding for the flow control port 2202, it has a water-blocking effect, preventing further liquid spillage.

[0202] Furthermore, the flow control ports 2202 can all be located on one side of the outlet 2201. The water tank 2000 can be equipped with a handle 2110, which is located on the opposite side of the outlet 2201, and the water tank 2000 as a whole is symmetrical about the connection line between the handle 2110 and the outlet 2201. Considering the user's usage habits, when the user holds the handle 2110 and carries the water tank 2000 while walking, the water tank 2000 will inevitably be slightly shaken. Each time it is shaken, the water in the water tank 2000 will inevitably tend to move in the opposite direction to the handle 2110, that is, in the direction of the outlet 2201.

[0203] If the flow control port 2202 is positioned in the liquid outflow direction (i.e., the pouring direction) of the outlet 2201, even if the water tank 2000 is locked, meaning the outlet 2201 is sealed and most of the water in the water tank 2000 is prevented from flowing out, some liquid may still be ejected from the flow control port 2202, which is positioned in the water outflow direction of the outlet 2201. Therefore, compared to the above structure, positioning the flow control port 2202 on the opposite side of the liquid outflow direction of the outlet 2201 can mitigate the occurrence of this phenomenon.

[0204] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0205] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
