Description

Technical Field

[0001] The present application relates to a water storage device, and in particular to an automatic water storage tank capable of displaying the status of the water tank. Background Art

[0002] In the prior art, some household water storage devices achieve automatic water storage in the water tank through an electric control device, for example, through the cooperation of a water level sensor and a solenoid valve. The defect of this method is that the control system needs to continuously keep the circuit closed. Once a power outage occurs, it cannot automatically store water.

[0003] There are also some that use the method of a float ball in the toilet water tank to control water inlet. The defect of this method is that the control structure is in long-term contact with the water in the water tank. Long-term immersion will generate scale at the gaps of the control structure, thus affecting the sensitivity of the control structure. Moreover, the rubber plug at its water outlet is prone to dislocation, resulting in the inability to block the water outlet, and the entire control structure needs to be replaced. Summary of the Invention

[0004] The purpose of the present application is to propose an automatic water storage tank that can achieve automatic water inlet, separate the water storage from the control unit at the same time, and extend the service life of the control unit.

[0005] The present application is implemented as follows: An automatic water storage tank includes a box body. The box body is divided into a non-connected control cavity located in the upper part and a water storage cavity located in the lower part. A drain pipe is connected to the bottom of the water storage cavity. A control unit is arranged in the control cavity. The control unit includes a piston tube with a cavity. The upper and lower parts of the piston tube are respectively communicated with a water source and the water storage cavity. A first piston that can move up and down is arranged in the upper part of the piston tube. The first piston is fixedly connected to a front indicator plate located on the upper side of the box body. A second piston that can move up and down is arranged in the lower part of the piston tube. The second piston is fixedly connected to a float ball located in the water storage cavity.

[0006] A through hole is opened at the upper end face of the control cavity. A gland with an opening is fixed in the hole. The upper port of the piston tube is connected to the gland. The upper end of the first piston is fixedly connected to a first piston rod. The upper end of the first piston rod extends out of the gland through the opening and is fixedly connected to the front indicator plate. A spring is sleeved outside the first piston rod.

[0007] A through hole is opened at the lower end face of the control cavity. A guide sleeve with a cavity is inserted into the through hole. The lower port of the piston tube is hermetically connected to the upper port of the guide sleeve. The lower end of the second piston is fixedly connected to a second piston rod. The second piston rod is inserted into the guide sleeve and is fixedly connected to a float ball located in the water storage cavity. A spring is sleeved outside the second piston rod.

[0008] A rear indicator plate with a fixed height is arranged on the upper end face of the box body behind the front indicator plate.

[0009] The guide sleeve includes a joint part and a guide part that are integrally connected. The outer diameter of the joint part is larger than that of the guide part, and an inward frustum is formed at the connection between the two.

[0010] The lower part of the floating ball is solid, and the upper part is hollow.

[0011] The upper part of the piston tube is provided with a water inlet and a water inlet pipe is installed. The lower part of the piston tube is provided with a water outlet and a water storage pipe is installed. The drainage end of the water storage pipe is communicated with the water storage cavity.

[0012] Due to the implementation of the above technical solutions, in this application, the floating ball (semi-solid ball) in the control unit and the corresponding spring can cooperate with the rising water level to block the water flow channel in the control unit and cut off the water inlet; the floating ball and the corresponding spring in the control unit can cooperate with the falling water level to conduct the water flow channel in the control unit and achieve the purpose of automatic water inlet. The height of the front indicator board can be adjusted by the up and down movement of the first piston. Whether the front indicator board covers the rear indicator board or not can visually show the water inlet and water cut-off. The control unit is separated from the water storage cavity in the water tank to avoid soaking and extend the service life of the control unit. The water inlet of the water storage cavity in this application is jointly controlled by the control unit and the valve, and the drainage of the water storage cavity is directly controlled by the valve to avoid the problem of drainage leakage. This application has a simple structure and is suitable for household use. Description of the Drawings

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0019] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0020] Embodiment: As Figure 1 , 2 , as shown in Figure 3, the automatic water storage tank includes a box body. The box body is divided into a non-connected control cavity 2 located in the upper part and a water storage cavity 1 located in the lower part. A drain pipe 10 is connected to the bottom of the water storage cavity 1. A control unit 6 is arranged in the control cavity 2. The control unit 6 includes a piston tube with a cavity. The upper and lower parts of the piston tube are respectively connected to a water source and the water storage cavity 1. A first piston 13 that can move up and down is arranged in the upper part of the piston tube. The first piston 13 is fixedly connected to a front indicator plate located on the upper side of the box body. A second piston 14 that can move up and down is arranged in the lower part of the piston tube. The second piston 14 is fixedly connected to a floating ball 17 located in the water storage cavity 1.

[0021] Further, a through hole is opened at the upper end face of the control cavity 2, that is, at the upper end face of the box body. A gland 12 with an opening is fixed in the hole. The upper port of the piston tube is connected to the gland 12. The upper end of the first piston 13 is fixedly connected to a first piston rod 11. The upper end of the first piston rod 11 extends out of the gland 12 through the opening and is fixedly connected to the front indicator plate 5. A spring is sleeved outside the first piston rod 11. The upper end of the spring abuts against the gland 12, and the lower end abuts against the first piston 13.

[0022] Further, a fixed-height rear indicator plate 4 is arranged at the upper end face of the box body behind the front indicator plate 5.

[0023] The front indicator 5 can be marked with water inflow, for example, with words indicating "water inflow" or with green; the rear indicator 4 can be marked with water outage, for example, with words indicating "no water inflow" or with red. When water inflows, the water flow will push the first piston 13 upward, and the front indicator 5 rises and gradually covers the rear indicator 4, indicating that water is inflowing. When water is not inflowing, the first piston 13 moves downward, and the front indicator 5 drops and completely exposes the rear indicator 4, indicating that water is not inflowing. Due to the height difference between the installation position of the water tank and the height of the human body, it is possible to see that the front indicator 5 has covered the rear indicator 4 when water is not inflowing. At this time, it can be judged according to the specific height of the front indicator 5. Multiple marks can be made on the first piston rod 11. When the top mark is exposed, it means that the first piston 13 moves upward under the influence of water pressure, indicating that water has entered the piston tube. When the second mark is exposed, it means that the water pressure in the piston tube continues to increase, and the water flow increases. At this time, the second piston 14 has moved downward significantly, and the piston tube is connected and water begins to flow in.

[0024] Furthermore, a through hole is provided at the lower end surface of the control chamber 2, that is, the upper end surface of the water storage chamber 1, in which a hollow guide sleeve 16 is inserted, and the lower end of the piston tube is sealed and connected to the upper end of the guide sleeve 16, and the lower end of the second piston 14 is fixedly connected to the second piston rod 15, and the second piston rod 15 is inserted into the guide sleeve 16 and fixedly connected to the float 17 located in the water storage chamber 1, and a spring is connected to the outer sleeve of the second piston rod 15, and the upper end of the spring touches the bottom surface of the second piston 14, and the lower end touches the upper end of the guide sleeve 16.

[0025] Furthermore, the guide sleeve 16 includes a joint part and a guide part which are integrally connected. The outer diameter of the joint part is larger than that of the guide part. An inward prism is formed at the connection between the two parts. The lower end of the piston tube is inserted into the joint part, and the lower end of the spring contacts the bottom surface of the joint part.

[0026] Furthermore, the lower part of the float 17 is solid, and the upper part is hollow.

[0027] Furthermore, a water inlet is provided at the upper portion of the piston tube, and a water inlet pipe 7 is installed thereon; a water outlet is provided at the lower portion of the piston tube, and a water storage pipe 3 is installed thereon; and a drainage end of the water storage pipe 3 is connected to the water storage chamber 1 .

[0028] Furthermore, the water inlet pipe 7 is connected to the indoor water inlet pipeline, and a valve is provided at the connection point.

[0029] Furthermore, the drainage pipe 11 is connected to a water unit in the room, and a valve is provided at the connection point. The water unit may be a water tank of a toilet, a water inlet pipe of a wash basin, etc.

[0030] Furthermore, the overall installation height of the box is higher than the water use unit.

[0031] Further, connecting members 9 for connecting with the wall are provided at the upper and lower parts of the box body.

[0032] When the water-using unit of the present application uses water and the water level in the water storage cavity 1 gradually decreases, the floating ball 17 begins to sink under the action of gravity, and the gravity is greater than the buoyancy force. The second piston 14 moves downward. At this time, the water flow entering the piston tube gradually increases, and the water pressure increases. The first piston 13 gradually moves upward under the action of the water pressure. As the water level further decreases, the floating ball 17 and the second piston 14 continue to move downward until the second piston 14 can no longer cover the water outlet, and the water flow begins to enter the water storage cavity 1. The lowest position of the second piston 14 is after the floating ball 17 is separated from the water surface. At this time, the water outlet is in the fully open state, and the water inflow into the water storage cavity 1 is the largest.

[0033] When the water-using unit stops using water, or when the amount of water entering the water storage cavity 1 is greater than the amount of water discharged, after the water level in the water storage cavity 1 gradually rises and contacts the floating ball 17, the floating ball 17 begins to rise under the combined action of the buoyancy force and the spring. During the rising process, the second piston 14 first gradually covers the water outlet. After completely covering the water outlet, no more water enters the water storage cavity 1. At this time, it is necessary for the second piston 14 to cover the water inlet at the same time. Therefore, the upper part of the second piston 14 needs to be designed as a frustum of a cone with a smaller upper diameter and a larger lower diameter, and the height of the frustum is greater than the height difference between the water inlet and the water outlet. In this way, after the second piston 14 completely covers the water outlet, it can also cover the water inlet at the same time, reducing the water flow entering the piston tube and lowering the water pressure. At this time, the first piston 13 moves downward under the action of the spring to cooperate with the second piston 14 to completely cover the water inlet.

[0034] By repeating the above process, the present application can achieve the purpose of automatically filling water into the water storage cavity 1.

[0035] The above technical features constitute the embodiments of the present application, which have strong adaptability and implementation effects. Non-essential technical features can be increased or decreased according to actual needs to meet the requirements of different situations.
