The core of the present invention is to provide a raw and waste water isolation water tank, which can be filled with raw water in the box structure in the initial state. With the continuous filtration of raw water, the space originally used for holding raw water can be converted into used for holding waste water. The space of the box structure can be used reasonably. Another core of the present invention is to provide a water purifier including the above-mentioned original and wastewater isolation water tank.

Please refer to Figures 1 to 3, Figure 1 is a schematic structural diagram of a specific embodiment of the original wastewater isolation tank provided by the present invention; Figure 2 is a front view of a funnel-shaped structure; Figure 3 is a front view of a piston.

The original and wastewater isolation water tank provided by this specific embodiment includes:

Box structure, initial chamber 1, at least one conversion chamber for containing raw water in the initial state, and after filtering the raw water inside, a conversion chamber 2 for containing wastewater and a raw water chamber 3 for containing raw water only ；

The interior of the initial chamber 1 is provided with a partition member that seals against its side wall so that the internal space of the initial chamber 1 is a raw water initial cavity for containing raw water and a waste water initial cavity for containing waste water; when the raw water initial cavity When the raw water is injected, the spacer moves to the initial cavity of the wastewater to increase the volume of the initial cavity of the raw water and reduce the volume of the initial cavity of the wastewater; when the wastewater is injected into the initial cavity of the wastewater, the spacer moves towards the initial cavity of the raw water to make the wastewater The initial cavity volume is increased, and the raw water initial cavity volume is reduced; the spacer is slidably arranged in the initial chamber 1;

An overflow port is provided near the upper port of the initial chamber 1 for overflowing the raw water in the initial chamber of the raw water to the conversion chamber 2 when the volume of the wastewater initial chamber increases, or the wastewater in the initial chamber after the raw water in the conversion chamber 2 is filtered The wastewater overflows to the conversion chamber 2;

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

In the actual use of the water purifier, when the raw water needs to be filtered, the raw water initial cavity, the conversion chamber 2 and the raw water chamber 3 are filled with raw water. During the water addition process, the spacer moves in the direction of the wastewater initial cavity To the bottom of the initial chamber 1, preferably, the volume of raw water added to the initial chamber is equal to the total volume of the initial chamber 1, and the raw water filtration starts: first, the raw water in the conversion chamber 2 is flowed out through the control device, and the conversion chamber The raw water in 2 is filtered. With the continuous outflow of the raw water, the volume of wastewater generated during the raw water filtration process increases. The wastewater enters the initial cavity of the wastewater, and the spacer moves in the direction of the initial cavity of the raw water, so that the wastewater used to contain the wastewater The volume of the initial cavity increases, and the volume of the raw water initial cavity decreases. The raw water in the raw water initial cavity overflows to the conversion chamber 2 through the overflow port until the filtering of the raw water in the conversion chamber 2 and the raw water initial cavity is completed; control the raw water cavity The raw water in the chamber 3 flows out and is 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.

Compared with the prior art, the original and wastewater isolation water tank of the present invention can fill the internal space with raw water in the initial state. During the process of filtering the raw water, the generated waste water continuously increases, and the waste water enters the waste water through the inlet valve 11 In the initial cavity, move the spacer in the direction of the raw water initial cavity, so that the volume of the raw water initial cavity is converted into the volume of the wastewater initial cavity, the volume of the wastewater initial cavity is increasing, and the volume of the raw water initial cavity is decreasing; and the conversion cavity 2. In the initial state, it can be used to hold raw water. After the internal raw water is filtered, it can be used to hold waste water. Under the condition that the total volume of the water tank remains unchanged, the volume of raw water that can be added at a time increases to avoid excessive Repeat the operation of adding raw water several times; the reasonable setting and full use of the volume of the water tank are realized.

In addition, compared with the elastic bladder in the prior art, the arrangement of the spacer member does not require repeated contraction and expansion, which improves the reliability of the water tank.

It should be noted that the spacer may be a sealing slider arranged inside the initial chamber 1. By moving 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 eliminated from each other. I am in a state of mutual transformation, but the total volume of these two parts of space remains unchanged.

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

The bottom of the initial chamber 1 is provided with a water inlet valve 11 for entering wastewater, and the bottoms of the conversion chamber 2 and the raw water chamber 3 are provided with water outlet valves.

After the detection mechanism detects that the raw water in the conversion chamber 2 has been filtered, the control device causes the raw water in the raw water chamber 3 to flow out through the outlet valve, filter the raw water in the raw water chamber 3, and filter the raw water in the raw water chamber 3 Afterwards, the generated wastewater flows into the initial wastewater chamber through the water inlet valve 11, or overflows from the overflow to the conversion chamber 2 after entering the wastewater initial chamber, until the raw water in the raw water chamber 3 is filtered.

On the basis of the above-mentioned embodiment, a conversion chamber 2 may be included, and the bottom of the conversion chamber 2 is provided with a first water outlet valve 21 for allowing raw water to flow out.

In the process of use, the raw water in the conversion chamber 2 is controlled to flow out and filtered. The waste water generated after the raw water in the conversion chamber 2 is filtered enters the wastewater initial chamber through the water inlet valve 11. As the filtering progresses , The generated waste water continues to increase, the volume of the initial waste water cavity continues to increase, and the volume of the raw water initial cavity continues to decrease. The raw water in the raw water initial cavity overflows from the overflow to the conversion chamber 2. Preferably, the raw water initial cavity and After the raw water in the conversion chamber 2 is filtered, the volume of waste water jointly produced 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 passed through the third outlet valve 31 Flow out and filter. The wastewater produced after filtration enters the wastewater initial cavity through the water inlet valve 11 until the raw water in the raw water initial cavity is filtered, and the raw water in the raw water chamber 3 is continuously controlled to be filtered; preferably, the raw water initial cavity, the conversion chamber 2 and the raw water The volume of waste water jointly produced after the raw water in the chamber 3 is filtered is less than or equal to the sum of the volumes of the initial chamber 1 and the conversion chamber 2. In the process of use, the volume of the raw water initial cavity can be converted into the volume of the wastewater initial cavity, and the raw water in the conversion chamber 2 can be used to hold wastewater after filtering, so that the space of the water tank can be reasonably used.

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.

On the basis of the above embodiment, the conversion chamber 2 can be made to include a first conversion chamber and a second conversion chamber. The bottom of the first conversion chamber is provided with a first outlet valve 21, and the bottom of the second conversion chamber is provided with a first outlet valve 21. Two water outlet valves 22; and the initial chamber 1 is provided with a first overflow port 12 for overflowing waste water to the first conversion chamber and a second overflow port 13 for overflowing waste water to the second conversion chamber; and The height of the first overflow port 12 is lower than the height of the second overflow port 13.

In the process of use, the raw water in the first conversion chamber is first controlled to flow out of the first outlet valve 21 and filtered. The waste water generated in the process of filtering the raw water in the first conversion chamber flows into the wastewater initial chamber through the inlet valve 11 , With the continuous increase of wastewater after filtration, the spacer moves to the direction of the original water initial cavity, the volume of the wastewater initial cavity continues to increase, and the volume of the raw water initial cavity continues to decrease, so that the raw water in the raw water initial cavity passes through the first overflow 12 overflow to the first conversion chamber, until the raw water in the first conversion chamber and the original water initial chamber is filtered, continue to control the raw water in the second conversion chamber to flow out and filter from the second outlet valve 22, resulting in Waste water enters the wastewater initial cavity through the inlet valve 11 or enters the wastewater initial cavity and overflows from the first overflow port 12 to the first conversion chamber until the detection device detects that the raw water in the second conversion chamber is filtered; continue to control The raw water in the raw water chamber 3 flows out through the third outlet valve 31 and is filtered. The waste water generated in the filtering process enters the wastewater initial cavity through the inlet valve 11, and when the wastewater initial cavity is full, it overflows from the overflow to the first The conversion chamber or the second conversion chamber is completed until the raw water in the raw water chamber 3 is filtered.

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

For example, when the total internal volume of the tank structure is 5L, the initial chamber 1 can be made according to the ratio of waste water produced by the raw water in the filtration process. The volume of the first conversion chamber is 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, here is just the ratio of raw water to wastewater commonly used The volume division performed, if the raw water purification method is replaced or the original purification equipment is replaced, the ratio of raw water to wastewater may be changed. Therefore, the specific volume division is determined according to the actual situation and will not be repeated here.

In order to more conveniently add raw water to the box structure, the raw water chamber 3 can be connected to the top of the second conversion chamber, and the upper part of the initial chamber 1 is provided with a funnel-shaped structure 5 that is convenient for adding raw water. Connect with the initial chamber 1.

During use, when raw water needs to be added, raw water can be added directly 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. And because the initial chamber 1 is provided with the first overflow port 12 and the second overflow port 13, the raw water will overflow to the first conversion chamber and the second conversion chamber, and the second conversion chamber and the raw water chamber 3 Therefore, the raw water will overflow from the second conversion chamber to the raw water chamber 3.

Preferably, it also includes an end cover for sealing, and the end cover is connected to the funnel-shaped structure 5.

It should be noted that since the volume of wastewater generated after the raw water is filtered is smaller than the volume of the original raw water, the volume of the wastewater initial chamber after the raw water in the initial chamber 1 is filtered is less than the volume of the initial chamber 1; The number is at least 1. When the number of conversion chamber 2 is 1, the total volume of waste water generated after filtering the raw water in the conversion chamber 2 and the waste water generated after filtering the raw water in the original water chamber is less 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, the number of conversion chambers 2 is N, where N is a positive integer greater than 2, and the conversion chamber 2 contains raw water The total volume of waste water produced after the raw water in the 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 N-1 conversion chambers 2 refer to the removal The conversion chamber 2 other than the last conversion chamber 2 where 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 for containing wastewater In a state that is not full or just full.
