Description

Technical Field

[0001] The present invention relates to the technical field of water purifier design, and more specifically, to a water tank for isolating raw water and waste water. In addition, the present invention also relates to a water purifier comprising the water tank for isolating raw water and waste water. Background Art

[0002] In the prior art, in order to separate the raw water and waste water of the water purifier, two independent water tanks are generally set up, one for holding the raw water and the other for holding the waste water generated after the raw water is purified. Since the waste water tank is empty in the initial state, this design method cannot reasonably utilize the water tank space.

[0003] In order to increase the volume of raw water that can be filtered in a single time as much as possible while keeping the total volume of the water tank unchanged, in the prior art, an elastic bag for collecting wastewater is provided in the water tank. In the initial state, the elastic bag is in a contracted state, and the entire volume of the water tank can be used to fill up with raw water. The wastewater generated during the raw water filtration process is collected in the elastic bag. As the volume of the raw water to be filtered continues to increase, the volume of the wastewater generated continues to increase, the space occupied by the raw water continues to decrease, and the elastic bag gradually expands and occupies the space originally used to hold the raw water, so that the wastewater is separated from the raw water, and the space of the water tank is fully utilized.

[0004] However, the elastic bladder needs to expand and contract continuously during operation, which will affect its service life. In addition, in order to ensure that the elastic bladder has good elasticity, the elastic bladder is generally thin in thickness when in an expanded state, and is easily damaged by impurities, causing wastewater leakage, making the reliability of the raw water filtration process low.

[0005] In summary, how to increase the maximum volume of raw water that can be added to the water tank at one time while ensuring reliability and keeping the total volume of the water tank unchanged is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a water tank for isolating raw water and waste water. In the initial state, the internal space of the water tank can be filled with raw water. As the raw water is filtered, the generated wastewater can occupy the space occupied by the raw water, thereby realizing the isolation of raw water and waste water and the rational use of the water tank space.

[0007] Another object of the present invention is to provide a water purifier comprising the above-mentioned raw water and waste water isolation tank.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] The initial chamber is provided with a partition member which is sealed against its side wall so that the internal space of the initial chamber is divided into a raw water initial chamber for holding raw water and a waste water initial chamber for holding waste water; the partition member is slidably arranged in the initial chamber;

[0012] An overflow port is provided near the upper port of the initial chamber to allow the raw water in the raw water initial chamber to overflow into the conversion chamber when the volume of the wastewater initial chamber increases, or the wastewater in the wastewater initial chamber to overflow into the conversion chamber after the raw water in the conversion chamber is filtered;

[0013] The initial chamber, the conversion chamber and the raw water chamber are all arranged in the box structure.

[0014] Preferably, a water inlet valve for allowing wastewater to enter the wastewater initial chamber is provided at the bottom of the initial chamber, and water outlet valves are provided at the bottom of the conversion chamber and the raw water chamber.

[0017] Preferably, the conversion chamber comprises a first conversion chamber and a second conversion chamber, a first water outlet valve is disposed at the bottom of the first conversion chamber, and a second water outlet valve is disposed at the bottom of the second conversion chamber.

[0018] Preferably, the initial chamber is provided with a first overflow port for allowing the wastewater to overflow into the first conversion chamber and a second overflow port for allowing the wastewater to overflow into the second conversion chamber;

[0019] And the height of the first overflow port is lower than the height of the second overflow port.

[0020] Preferably, the total volume of the raw water in the first conversion chamber and the wastewater generated during the filtration process of the raw water in the raw water initial chamber is less than or equal to the volume of the initial chamber;

[0021] The total volume of wastewater generated during the raw water filtration process in the first conversion chamber, the raw water initial chamber, and the second conversion chamber is less than or equal to the sum of the volumes of the initial chamber and the first conversion chamber;

[0022] The total volume of wastewater generated during the raw water filtration process in the first conversion chamber, the raw water initial chamber, the second conversion chamber, and the raw water chamber is less than or equal to the sum of the volumes of the initial chamber, the first conversion chamber, and the second conversion chamber.

[0023] Preferably, the raw water chamber is communicated with the top of the second conversion chamber, and a funnel-shaped structure for conveniently adding the raw water is provided on the upper portion of the initial chamber, and the funnel-shaped structure is communicated with the initial chamber.

[0024] Preferably, the spacing member is a piston, and the piston is movably arranged along the height direction of the initial chamber.

[0025] A water purifier comprises a water tank for containing raw water and waste water, a filtering system for filtering the raw water, and a main structure for installing the water tank and the filtering system. The water tank is the raw water and waste water isolation tank mentioned in any one of the above items.

[0026] The beneficial effects of the present invention are:

[0027] Compared with the prior art, the spacing component realizes the conversion of the spatial volume of the wastewater initial cavity and the raw water initial cavity by moving the spacing component, which improves the reliability of the spatial conversion process between the wastewater initial cavity and the raw water initial cavity and avoids the trouble of frequent replacement of parts.

[0028] The setting of the conversion chamber allows the space for holding raw water and the space for holding waste water to be converted into each other. Under the condition that the total volume of the water tank remains unchanged, the layout of the water tank is more reasonable and the space utilization rate is improved. In addition, the reliability of the water tank structure can be increased by arranging the initial chamber, the conversion chamber and the raw water chamber in the box structure.

[0029] The raw water and waste water isolation water tank provided by the present invention comprises: a box structure, an initial chamber, at least one conversion chamber for holding raw water in an initial state and for holding waste water after the raw water inside the conversion chamber is filtered, and a raw water chamber for holding raw water only; a partition member is slidably arranged inside the initial chamber, and the partition member is sealed against the side wall of the initial chamber, so that the internal space of the initial chamber is divided into a raw water initial chamber for holding raw water and a waste water initial chamber for holding waste water;

[0030] An overflow port is provided near the upper port of the initial chamber to allow the raw water in the initial chamber to overflow into the conversion chamber when the volume of the initial chamber increases, or the waste water in the initial chamber to overflow into the conversion chamber after the raw water in the conversion chamber is filtered;

[0031] The initial chamber, the conversion chamber and the raw water chamber are all arranged in the box structure.

[0032] During use, when it is necessary to filter the raw water, the spacing component can be moved to the position where the volume of the wastewater initial chamber is zero, and the raw water initial chamber, the conversion chamber and the raw water chamber are filled with raw water to start filtering the raw water; first, the raw water in the conversion chamber is controlled to flow out through the control device, and the raw water in the conversion chamber is filtered. As the raw water is continuously filtered, the wastewater generated increases continuously, and the wastewater enters the wastewater initial chamber through the water inlet valve, so that the spacing component moves upward, and the volume of the wastewater initial chamber increases continuously. The raw water in the raw water initial chamber overflows from the overflow port to the conversion chamber until the raw water in the conversion chamber and the raw water initial chamber is filtered; then the raw water in the raw water chamber is controlled to flow out and be filtered, and the wastewater generated during the filtration process enters the wastewater initial chamber and overflows to the conversion chamber through the overflow port until the raw water in the raw water chamber is filtered.

[0033] Compared with the prior art, the raw water and waste water isolation water tank in the present invention can be filled with raw water in the internal space in the initial state. During the filtration of the raw water, the increase of waste water in the wastewater initial chamber pushes the spacing component to move in the direction of the raw water initial chamber. The movement of the spacing component causes the raw water initial chamber and the wastewater initial chamber to transform into each other, and the volume of the wastewater initial chamber continues to increase, while the volume of the raw water initial chamber continues to decrease. The conversion chamber can be used to hold raw water in the initial state, and can be used to hold waste water after the raw water inside it is filtered. When the total volume of the water tank remains unchanged, the volume of raw water that can be added at a single time is increased, and there is no need to reduce the single amount of raw water added in order to store waste water, thereby avoiding the operation of repeatedly adding raw water. The reasonable setting and full utilization of the water tank space volume are achieved.

[0034] In addition, compared with the elastic bag in the prior art, the spacer component does not need to be repeatedly contracted and expanded, so the reliability of the water tank is improved.

[0035] The present invention also provides a water purifier comprising the above-mentioned raw water and waste water isolation tank. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The core of the present invention is to provide a water tank for isolating raw water and waste water, which can be filled with raw water in the box structure in the initial state. As the raw water is continuously filtered, the space originally used to hold raw water can be converted into space for holding waste water, so that the space of the box structure is reasonably utilized. Another core of the present invention is to provide a water purifier including the above-mentioned water tank for isolating raw water and waste water.

[0044] Please refer to Figure 1-Figure 3 , Figure 1 This is a schematic structural diagram of a specific embodiment 1 of the raw water and waste water isolation tank provided by the present invention; Figure 2 It is a front view of the funnel-shaped structure; Figure 3 This is a front view of the piston.

[0045] The raw water and waste water isolation tank provided in this specific embodiment includes:

[0046] A box structure, an initial chamber 1, at least one conversion chamber 2 for holding raw water in an initial state and for holding waste water after the raw water inside is filtered, and a raw water chamber 3 for holding raw water only;

[0047] The initial chamber 1 is provided with a partition member which is sealed against its side wall so that the internal space of the initial chamber 1 is divided into a raw water initial chamber for holding raw water and a wastewater initial chamber for holding wastewater; when raw water is injected into the raw water initial chamber, the partition member moves toward the wastewater initial chamber so that the volume of the raw water initial chamber increases and the volume of the wastewater initial chamber decreases; when wastewater is injected into the wastewater initial chamber, the partition member moves toward the raw water initial chamber so that the volume of the wastewater initial chamber increases and the volume of the raw water initial chamber decreases; the partition member is slidably arranged in the initial chamber 1;

[0048] An overflow port is provided near the upper port of the initial chamber 1 to allow the raw water in the initial chamber to overflow to the conversion chamber 2 when the volume of the initial chamber increases, or the waste water in the initial chamber to overflow to the conversion chamber 2 after the raw water in the conversion chamber 2 is filtered;

[0049] The initial chamber 1, the conversion chamber 2 and the raw water chamber 3 are all arranged in the box structure.

[0050] During the actual use of the water purifier, when it is necessary to filter the raw water, fill the raw water initial chamber, the conversion chamber 2 and the raw water chamber 3 with raw water. During the water adding process, the spacer moves toward the direction of the wastewater initial chamber to the bottom of the initial chamber 1. Preferably, the volume of raw water added to the raw water initial chamber is equal to the total volume of the initial chamber 1, and the raw water filtration begins: first, the raw water in the conversion chamber 2 is made to flow out through the control device, and the raw water in the conversion chamber 2 is filtered. As the raw water continues to flow out, the water in the raw water filtration process is reduced. The volume of the generated wastewater increases, and the wastewater enters the wastewater initial chamber. The spacing component moves toward the direction of the raw water initial chamber, so that the volume of the wastewater initial chamber for holding the wastewater increases, and the volume of the raw water initial chamber decreases. The raw water in the raw water initial chamber overflows to the conversion chamber 2 through the overflow port until the raw water in the conversion chamber 2 and the raw water initial chamber is filtered; the raw water in the raw water chamber 3 is controlled to flow out and be filtered, and the generated wastewater overflows from the overflow port to the conversion chamber 2 through the wastewater initial chamber until the raw water in the raw water chamber 3 is filtered.

[0051] Compared with the prior art, the raw water and waste water isolation water tank in the present invention can be filled with raw water in the internal space in the initial state. During the filtration process of the raw water, the waste water generated increases continuously, and the waste water enters the waste water initial chamber through the water inlet valve 11, so that the partition component moves toward the raw water initial chamber, so that the volume of the raw water initial chamber is converted into the volume of the waste water initial chamber, and the volume of the waste water initial chamber increases continuously, while the volume of the raw water initial chamber decreases continuously; and the conversion chamber 2 can be used to hold raw water in the initial state, and can be used to hold waste water after the raw water inside it is filtered. When the total volume of the water tank remains unchanged, the volume of raw water that can be added at a single time is increased, avoiding the operation of repeatedly adding raw water; the reasonable setting and full utilization of the water tank space volume are realized.

[0052] In addition, compared with the elastic bag in the prior art, the spacer component does not need to be repeatedly contracted and expanded, so the reliability of the water tank is improved.

[0053] It should be noted that the spacing component can be a sealing slider arranged inside the initial chamber 1. Through the movement of the sealing slider, the internal space of the initial chamber 1 can be divided into two parts, and the two parts of the space are in a state of mutual transformation in which one part increases while the other decreases, but the total volume of the two parts of the space remains unchanged.

[0054] It should be noted that the volumes of the raw water initial chamber and the wastewater initial chamber change with the movement of the spacer component, but the total volume of the two is always equal to the volume of the initial chamber 1. In the initial state, the volume of the wastewater initial chamber is zero, and the volume of the raw water initial chamber filled with raw water is equal to the volume of the initial chamber 1. When the volume of the raw water initial chamber is zero, the volume of the wastewater initial chamber is equal to the volume of the initial chamber 1.

[0055] A water inlet valve 11 for allowing waste water to enter is provided at the bottom of the initial chamber 1 , and a water outlet valve is provided at the bottom of the conversion chamber 2 and the raw water chamber 3 .

[0056] After the detection mechanism detects that the raw water in the conversion chamber 2 has been filtered, the raw water in the raw water chamber 3 is made to flow out from the water outlet valve through the control device, and the raw water in the raw water chamber 3 is filtered, and the wastewater generated after the raw water in the raw water chamber 3 is filtered flows into the wastewater initial chamber through the water inlet valve 11, or overflows from the overflow port to the conversion chamber 2 after entering the wastewater initial chamber, until the filtration of the raw water in the raw water chamber 3 is completed.

[0057] On the basis of the above embodiment, a conversion chamber 2 may be included, and a first water outlet valve 21 for allowing raw water to flow out is arranged at the bottom of the conversion chamber 2 .

[0058] During use, the raw water in the conversion chamber 2 is first controlled to flow out and filtered. The waste water generated after the raw water in the conversion chamber 2 is filtered enters the waste water initial chamber through the water inlet valve 11. As the filtering proceeds, the waste water generated continues to increase, the volume of the waste water initial chamber continues to increase, and the volume of the raw water initial chamber continues to decrease. The raw water in the raw water initial chamber overflows from the overflow port to the conversion chamber 2. Preferably, the volume of the waste water generated after the raw water initial chamber and the raw water in the conversion chamber 2 are filtered is less than or equal to the volume of the initial chamber 1. After the raw water in the conversion chamber 2 is filtered, the raw water in the raw water chamber 3 is made to flow out and be filtered through the third water outlet valve 31. The waste water generated after filtering enters the waste water initial chamber through the water inlet valve 11 until the raw water in the raw water initial chamber is filtered, and the raw water in the raw water chamber 3 is continuously controlled to be filtered. Preferably, the volume of the waste water generated after the raw water in the raw water initial chamber, the conversion chamber 2, and the raw water chamber 3 is less than or equal to the sum of the volumes of the initial chamber 1 and the conversion chamber 2. During use, the volume of the raw water initial chamber can be converted into the volume of the waste water initial chamber. After the raw water in the conversion chamber 2 is filtered, it can be used to hold waste water, so that the space of the water tank is reasonably utilized.

[0059] Preferably, the ratio of the volume of the initial chamber 1, the volume of the conversion chamber 2, and the volume of the raw water chamber 3 can be: the volume of the initial chamber 1: the volume of the conversion chamber 2: the volume of the raw water chamber 3 = 1:1:2. For example, when the total volume of the water tank is 5L, the volume of the initial chamber 1 is 1.25L, the volume of the conversion chamber 2 is 1.25L, and the volume of the raw water chamber 3 is 2.5L.

[0060] On the basis of the above embodiment, the conversion chamber 2 can include a first conversion chamber and a second conversion chamber, a first water outlet valve 21 is provided at the bottom of the first conversion chamber, and a second water outlet valve 22 is provided at the bottom of the second conversion chamber; and the initial chamber 1 is provided with a first overflow port 12 for allowing waste water to overflow into the first conversion chamber and a second overflow port 13 for allowing waste water to overflow into the second conversion chamber; and the height of the first overflow port 12 is lower than the height of the second overflow port 13.

[0061] During use, the raw water in the first conversion chamber is first controlled to flow out from the first water outlet valve 21 and be filtered. The waste water generated during the raw water filtration process in the first conversion chamber flows into the waste water initial chamber through the water inlet valve 11. As the waste water after filtration continues to increase, the spacing component moves toward the raw water initial chamber, the volume of the waste water initial chamber continues to increase, and the volume of the raw water initial chamber continues to decrease, so that the raw water in the raw water initial chamber overflows to the first conversion chamber through the first overflow port 12, until the raw water in the first conversion chamber and the raw water initial chamber is filtered, and then the second conversion chamber is controlled continuously. The raw water in the raw water chamber 3 flows out through the second water outlet valve 22 and is filtered, and the generated wastewater enters the wastewater initial chamber through the water inlet valve 11 or overflows from the first overflow port 12 to the first conversion chamber after entering the wastewater initial chamber, until the detection device detects that the filtration of the raw water in the second conversion chamber is completed; the raw water in the raw water chamber 3 continues to be controlled to flow out and be filtered through the third water outlet valve 31, and the wastewater generated during the filtration process enters the wastewater initial chamber through the water inlet valve 11. When the wastewater initial chamber is full, it overflows from the overflow port to the first conversion chamber or the second conversion chamber, until the filtration of the raw water in the raw water chamber 3 is completed.

[0062] The total volume of wastewater generated during the filtration of raw water in the first conversion chamber and the raw water initial chamber can be made less than or equal to the volume of the initial chamber 1; the total volume of wastewater generated during the filtration of raw water in the first conversion chamber, the raw water initial chamber and the second conversion chamber can be made less than or equal to the sum of the volumes of the initial chamber 1 and the first conversion chamber; the total volume of wastewater generated during the filtration of raw water in the first conversion chamber, the raw water initial chamber, the second conversion chamber and the raw water chamber 3 can be made less than or equal to the sum of the volumes of the initial chamber 1, the first conversion chamber and the second conversion chamber.

[0063] Preferably, the wastewater generated after the raw water in the raw water initial chamber and the first conversion chamber is filtered just fills the initial chamber 1, the wastewater generated after the raw water in the second conversion chamber is filtered just fills the first conversion chamber, and the wastewater generated after the raw water in the raw water chamber 3 is filtered just fills the second conversion chamber; the volume of the initial chamber 1: the volume of the first conversion chamber: the volume of the second conversion chamber: the volume of the raw water chamber 3 = 1:1:2:4. For example, when the total volume inside the box structure is 5L, According to the ratio of raw water to wastewater generated during the filtration process, the volume of the initial chamber 1 can be 0.625L, the volume of the first conversion chamber is 0.625L, the volume of the second conversion chamber is 1.25L, and the volume of the raw water chamber 3 is 2.5L; of course, the volume division here is only based on the commonly used ratio of raw water to wastewater. If the raw water purification method is changed or the original purification equipment is replaced, the ratio of raw water to wastewater may change. Therefore, the specific volume division is determined according to the actual situation and will not be elaborated here.

[0064] In order to more conveniently add raw water into the box structure, the raw water chamber 3 can be connected to the top of the second conversion chamber, and a funnel-shaped structure 5 for convenient addition of raw water is provided on the upper part of the initial chamber 1, and the funnel-shaped structure 5 is connected to the initial chamber 1.

[0065] During use, when raw water needs to be added, the raw water can be directly added to the funnel-shaped structure 5. Since the funnel-shaped structure 5 is connected to the initial chamber 1, the raw water will directly enter the initial chamber 1 through the funnel-shaped structure 5. Since the initial chamber 1 is provided with a first overflow port 12 and a second overflow port 13, the raw water will overflow into the first conversion chamber and the second conversion chamber, and the second conversion chamber is connected to the raw water chamber 3, so the raw water will overflow from the second conversion chamber to the raw water chamber 3.

[0066] Preferably, an end cover for sealing is also included, and the end cover is connected to the funnel-shaped structure 5 .

[0067] Preferably, the spacer component is a piston 4, and the piston 4 is movably arranged along the height direction of the initial chamber 1; the piston 4 can be a cylindrical piston, and a cylindrical chamber for cooperating with the cylindrical piston is arranged inside the initial chamber 1, and the piston 4 moves up and down in the cylindrical chamber to realize the conversion between the raw water initial chamber and the wastewater initial chamber.

[0068] It should be noted that, since the volume of wastewater generated after raw water filtration is smaller than the original volume of raw water, the volume of the initial chamber of wastewater after raw water filtration in the initial chamber 1 is smaller than the volume of the initial chamber 1; the number of conversion chambers 2 is at least 1, and when the number of conversion chambers 2 is 1, the total volume of the wastewater generated after raw water filtration in the conversion chamber 2 and the wastewater generated after raw water filtration in the initial chamber of raw water is smaller than or equal to the total volume of the initial chamber 1; when the number of conversion chambers 2 is 2, 3 or more, for example If the number of conversion chambers 2 is N, N is a positive integer greater than 2, the total volume of wastewater generated after the raw water in the conversion chamber 2 and the raw water initial chamber is filtered is less than or equal to the sum of the volume of the initial chamber 1 and the total volume of N-1 conversion chambers 2, where the N-1 conversion chambers 2 refer to the other conversion chambers 2 except the last conversion chamber 2 in which the raw water is filtered, and after the raw water in any conversion chamber 2 is filtered, the initial chamber 1 or the previous conversion chamber 2 used to hold the wastewater is in a state of not full or just full.

[0069] In addition to the above-mentioned raw water and waste water isolation water tank, the present invention also provides a water purifier including the raw water and waste water isolation water tank disclosed in the above-mentioned embodiment, the water purifier includes a water tank for holding raw water and waste water, a filtering system for filtering raw water, and a main structure for installing the water tank and the filtering system, and the water tank is the raw water and waste water isolation water tank mentioned in any of the above items; for the structures of other parts of the water purifier, please refer to the prior art and will not be repeated in this article.

[0070] Preferably, the opening and closing of the first water outlet valve 21, the second water outlet valve 22, the third water outlet valve 31 and the water inlet valve 11, which are preferentially configured as solenoid valves, can be controlled by an electromagnetic induction switch provided in the water purifier.

[0071] On the basis of the above embodiment, in order to be able to pour out the waste water in time after the raw water is filtered and replenish the raw water, a liquid shortage sensor for detecting the raw water level and an alarm device for alarming in the liquid shortage state can be provided in the raw water chamber 3. The liquid shortage sensor is connected to the controller, and the controller is connected to the alarm device.

[0072] The alarm device can be a buzzer or an alarm light, which is determined according to actual conditions. Preferably, the liquid shortage sensor is arranged at the bottom of the raw water chamber 3.

[0073] It should be noted that the first, second, and third in the first conversion chamber and the second conversion chamber, the first water outlet valve 21, the second water outlet valve 22 and the third water outlet valve 31, the first overflow port 12 and the second overflow port 13 mentioned in the present application document are only for distinguishing the terms of different technical features. There is no order of precedence and they do not constitute a limitation on the technical solution of the present invention.

[0074] It should be noted that the overflow port mentioned in the present solution can be a flow port or hole opened on the wall of the initial chamber 1, or directly a port on the top of the wall of the initial chamber 1 adjacent to the conversion chamber 2. For the case of two conversion chambers 2, for example, the height of the port on the top of the wall of the initial chamber 1 adjacent to the conversion chamber 2 can be set to unequal heights to achieve overflow in sequence. The overflow port is not limited to a specific structure as long as the purpose of overflow can be achieved.

A water tank for isolating raw and waste water, characterized in that: include: A box structure, an initial chamber (1), at least one conversion chamber (2) for containing raw water in an initial state and for containing waste water after the raw water is filtered, and a raw water chamber (3) for containing raw water only; The initial chamber (1) is provided with a partition member which is sealed against its side wall so that the internal space of the initial chamber (1) is divided into a raw water initial chamber for holding raw water and a waste water initial chamber for holding waste water; the partition member is slidably arranged in the initial chamber (1); An overflow port is provided near the upper port of the initial chamber (1) for allowing the raw water in the initial raw water chamber to overflow into the conversion chamber (2) when the volume of the initial waste water chamber increases, or for allowing the waste water in the initial waste water chamber to overflow into the conversion chamber (2) after the raw water in the conversion chamber (2) is filtered; The initial chamber (1), the conversion chamber (2) and the raw water chamber (3) are all arranged in the box structure; The bottom of the initial chamber (1) is provided with a water inlet valve (11) for allowing wastewater to enter the wastewater initial chamber, and the bottoms of the conversion chamber (2) and the raw water chamber (3) are provided with water outlet valves; The conversion chamber (2) comprises a first conversion chamber and a second conversion chamber, the first conversion chamber is provided with a first water outlet valve (21) at the bottom, and the second conversion chamber is provided with a second water outlet valve (22) at the bottom; The initial chamber (1) is provided with a first overflow port (12) for allowing the wastewater to overflow into the first conversion chamber and a second overflow port (13) for allowing the wastewater to overflow into the second conversion chamber; and the height of the first overflow port (12) is lower than the height of the second overflow port (13); The total volume of the raw water in the first conversion chamber and the wastewater generated during the filtration process of the raw water in the raw water initial chamber is less than or equal to the volume of the initial chamber (1); The total volume of wastewater generated during the raw water filtration process in the first conversion chamber, the raw water initial chamber, and the second conversion chamber is less than or equal to the sum of the volumes of the initial chamber (1) and the first conversion chamber; The total volume of wastewater generated during the raw water filtration process in the first conversion chamber, the raw water initial chamber, the second conversion chamber, and the raw water chamber (3) is less than or equal to the sum of the volumes of the initial chamber (1), the first conversion chamber, and the second conversion chamber; During use, the raw water in the first conversion chamber is first controlled to flow out through the first water outlet valve (21) and be filtered. The waste water generated during the filtering process of the raw water in the first conversion chamber flows into the waste water initial chamber through the water inlet valve (11). As the amount of waste water increases after filtering, the spacing component moves toward the raw water initial chamber, the volume of the waste water initial chamber increases, and the volume of the raw water initial chamber decreases, so that the raw water in the raw water initial chamber overflows into the first conversion chamber through the first overflow port (12). Until the filtering of the raw water in the first conversion chamber and the raw water initial chamber is completed, the second conversion chamber is controlled to continue to flow out. The raw water flows out from the second water outlet valve (22) and is filtered, and the waste water generated enters the waste water initial chamber through the water inlet valve (11) or overflows from the first overflow port (12) to the first conversion chamber after entering the waste water initial chamber, until the detection device detects that the filtration of the raw water in the second conversion chamber is completed; the raw water in the raw water chamber (3) is continuously controlled to flow out from the third water outlet valve (31) and be filtered, and the waste water generated during the filtration process enters the waste water initial chamber through the water inlet valve (11), and when the waste water initial chamber is full, it overflows from the overflow port to the first conversion chamber or the second conversion chamber, until the filtration of the raw water in the raw water chamber (3) is completed; The raw water chamber (3) is connected to the top of the second conversion chamber, and a funnel-shaped structure (5) is provided on the top of the initial chamber (1) for conveniently adding the raw water, and the funnel-shaped structure (5) is connected to the initial chamber (1).

2. The raw water and waste water isolation tank according to claim 1 is characterized in that: The spacing component is a piston (4), and the piston (4) is movably arranged along the height direction of the initial chamber (1).

3. A water purifier, comprising a water tank for containing raw water and waste water, a filtering system for filtering the raw water, and a main structure for installing the water tank and the filtering system, characterized in that: The water tank is the raw water and waste water isolation tank mentioned in claim 1 or 2.
