[0002] With the increasing popularity of low-profile toilets, the flushing effect of toilets is also facing a greater test. Since the water tank is required to be set as low as possible above the upper surface of the toilet seat, the potential energy of the water in the low-level water tank is not enough to effectively flush the toilet. In order to solve this problem, some low-profile toilets are equipped with water tanks and water pumps for pressurization for flushing, realizing zero-gravity water flushing, but the waterway structure is relatively complex, the cost is high, and the problem of power outages and inability to flush needs to be considered. Some low-profile toilets are directly flushed with tap water, specifically, a flush valve is used to connect the tap water pipeline. When flushing, the flush valve is opened, and the tap water enters the internal waterway of the toilet for flushing. However, this flushing method has the following shortcomings: when the tap water pressure is low or the flow rate is small, there is a problem of low flushing force and insufficient flushing flow per unit time, which affects the flushing effect.

[0007] Furthermore, the inner diameter of the first chamber is smaller than the inner diameter of the second chamber, so that a limiting step surface facing the second chamber is formed between the first chamber and the second chamber, and the movable part engages with the limiting step surface when moving toward the first chamber.

[0008] Furthermore, the first chamber is located above the second chamber, the movable part is a float, and the water outlet is located at the bottom end of the second chamber.

[0009] Furthermore, the edges around the connecting port are provided with a first sealing flange protruding toward the second chamber and in an annular shape, and when the movable part moves to the first chamber and reaches its position, a first sealing gasket arranged thereon abuts against the first sealing flange.

[0010] Furthermore, the water inlet channel passes through the first chamber and the second chamber, and the movable part is sleeved outside the water inlet channel, so that the water inlet channel provides guidance for the movement of the movable part.

[0011] Furthermore, an installation channel extending toward the second chamber is provided at one end of the first chamber away from the second chamber, the water inlet channel seal is penetrated through the installation channel, the tail end of the installation channel extends into the connecting port, and the movable part is sealed with the tail end of the installation channel when it moves into position toward the first chamber.

[0012] Furthermore, a second sealing flange protruding toward the second chamber and in an annular shape is provided at the rear end of the installation channel, and when the movable part moves into position in the direction of the first chamber, a second sealing gasket provided thereon abuts against the second sealing flange.

[0013] Furthermore, the water storage body includes a first shell, a second shell and the water inlet channel, the first shell and the second shell are sealed and connected to enclose the water storage cavity, the water outlet is arranged in the second shell, the water inlet channel is sealed and connected to the first shell, and one end of the water inlet channel is located outside the first shell, and one end of the water inlet channel extends through the water storage cavity to the water outlet.

[0016] The present invention further provides a toilet, comprising a toilet body and a flushing device as described in the present invention, wherein the water outlet end of the flushing valve is connected to the jet water path and / or the brush ring water path of the toilet body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Since the enclosed water storage body of the present invention is provided with a water storage chamber, a water inlet channel and a water outlet, the water inlet channel is supplied with tap water, and one end of the water inlet channel is the water inlet end, and the other end of the water inlet channel enters the water outlet from the water storage chamber toward the water outlet, and forms a water gap communicating with the water storage chamber between the water inlet channel and the water outlet, when the water outlet or the flow path connected to it is closed, the water flowing into the water inlet channel enters the water storage chamber from the water gap and compresses the air, and when the water outlet or the flow path connected to it is opened again, the water in the water storage chamber and the water flowing into the water inlet channel are discharged through the water outlet together, Therefore, when the present invention is used for flushing, it can not only utilize the pressure of the tap water itself for flushing, but also utilize the water in the water storage chamber for flushing. The water in the water storage chamber is quickly discharged under the combined action of the pressure of the compressed air, the gravity of the water itself, and the negative pressure generated by the ejector structure formed by the other end of the water inlet channel located in the water outlet. As a result, the present invention can stabilize the drainage pressure and play a pressure stabilizing role when the tap water pressure is low and the flow rate is small. At the same time, the water storage body and the tap water are drained in parallel, which can greatly increase the drainage flow rate and the flushing intensity, thereby improving the flushing effect.

[0020] 2. The present invention further provides a water inlet limiting structure for limiting the maximum water inlet of the water storage chamber, so that the water inlet stops when the water in the water storage chamber reaches a preset maximum water inlet, thereby preventing the water storage chamber from inletting too much water and over-compressing the air, thereby avoiding the risk of the water storage body bursting when the internal air pressure is too high.

[0021] 3. The water inlet limiting structure preferably includes a movable part movably arranged in the second chamber. When water enters the second chamber, the movable part moves toward the first chamber under the action of water pressure and / or buoyancy until the connecting port between the first chamber and the second chamber is closed, so that the water inlet limiting structure is relatively simple and easy to assemble, and does not require additional driving force, which is more energy-saving and environmentally friendly.

[0022] 4. The movable part is sleeved outside the water inlet channel, so that the water inlet channel provides a guide for the movement of the movable part, which can ensure the working stability of the movable part and avoid the need to set up an additional guide structure for the movable part.

In the description, the orientations or positional relationships indicated by "upper", "lower", "inner", "outer", "top / bottom", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0034] In addition, in the description of the present invention, "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0035] See also Figure 1-Figure 8 As shown, a pressure-stabilizing and flow-increasing water storage device of the present invention includes a closed water storage body 10, and the water storage body 10 is specifically in the shape of a tank, so it can also be called a water storage tank, but is not limited to this. The water storage body 10 is provided with a water storage chamber 4, a water inlet channel 1 and a water outlet 31, and the water outlet 31 is specifically arranged at the bottom of the water storage body 10 and connected to the water storage chamber 4. The water inlet channel 1 is supplied with tap water, and one end of the water inlet channel 1 is the water inlet end, and the other end of the water inlet channel 1 is the water outlet end and enters the water outlet 31 from the water storage chamber 4 to the direction of the water outlet 31, and a water gap 32 connecting the water storage chamber 4 is formed between the other end of the water inlet channel 1 and the water outlet 31. Specifically, one end of the water inlet channel 1 is located outside the top of the water storage body 10, and the other end of the water inlet channel 1 passes through the water storage chamber 4 and enters the water outlet 31. When the water outlet 31 or the flow path connected to it is closed, the water flowing into the water inlet channel 1 enters the water storage chamber 4 from the water gap 32 and compresses the air in the water storage chamber 4; when the water outlet 31 or the flow path connected to it is opened again, the compressed air in the water storage chamber 4 releases the pressure, and the water in the water storage chamber 4 and the water flowing into the water inlet channel 1 (i.e., tap water) are drained together through the water outlet 31. The opening and closing of the water outlet 31 or the flow path connected to it can be controlled by a valve, such as the flush valve mentioned below.

[0036] As a preferred embodiment, the present invention also includes a water inlet limiting structure, which is used to limit the maximum water inlet of the water storage chamber 4, so that the water inlet stops when the water in the water storage chamber 4 reaches a preset maximum water inlet, thereby avoiding excessive water inflow into the water storage chamber 4 and excessive compression of the air, thereby avoiding the risk of the water storage body 10 bursting due to excessive internal air pressure.

[0037] In this embodiment, the water storage chamber 4 includes a first chamber 41 and a second chamber 42, a communication port 43 is provided between the first chamber 41 and the second chamber 42, and the water outlet 31 and the water gap 32 are connected to the second chamber 42. The water inlet limiting structure includes a movable part movably arranged in the second chamber 42. When water enters the second chamber 42, the movable part moves toward the first chamber 41 under the action of water pressure and / or buoyancy until the communication port 43 is closed, thereby isolating the water in the second chamber 42 and the air in the first chamber 41, that is, limiting the inflow of water into the first chamber 41, thereby controlling the maximum water inflow of the water storage chamber 4. The inner diameter of the first chamber 41 is smaller than the inner diameter of the second chamber 42, so that a limiting step surface facing the second chamber 42 is formed between the first chamber 41 and the second chamber 42, and the movable part moves toward the first chamber 41 when it is matched with the limiting step surface.

[0038] In other embodiments, the water inlet limit structure includes an electrically controlled water inlet valve and a water level sensor. The water inlet valve is installed on the water inlet channel, specifically at one end of the water inlet channel, to control whether water enters the water inlet channel. The water level sensor is installed on the water storage body and detects the water level of the water storage body in real time. The water level sensor sends the real-time detected water level information to the main control board connected to the water inlet valve. When the water level in the water storage chamber 4 reaches a preset value, the main control board controls the water inlet valve to close; when flushing, the water inlet valve and the water outlet are both opened.

[0039] In this embodiment, the first chamber 41 is located above the second chamber 42, and the movable part is the float 20, but it is not limited to this. In other embodiments, the movable part is a piston. In this case, the first chamber can be located on the side of the second chamber. The edges around the communication port 43 are provided with a circle of first sealing flanges 22 protruding toward the second chamber 42. The first sealing flanges 22 are specifically provided on the above-mentioned limiting step surface. When the movable part (i.e., the float 20) moves to the direction of the first chamber 41 and reaches the position, the first sealing pad 30 provided on the float 20 abuts against the first sealing flange 22.

[0040] The water inlet channel 1 passes through the first chamber 41 and the second chamber 42, and the above-mentioned movable part (i.e., the float 20) is sleeved outside the water inlet channel 1, so that the water inlet channel 1 provides guidance for the movement of the movable part (i.e., the float 20), thereby ensuring the stability of the operation of the float 20 and avoiding the need to set up an additional guide structure for the float 20. A mounting channel 21 extending toward the second chamber 42 is provided in the middle of one end of the first chamber 41 away from the second chamber 42 (i.e., the top of the first chamber 41), and the water inlet channel 1 is sealed and penetrated through the mounting channel 21. The tail end of the mounting channel 21 (i.e., the end of the mounting channel 21 facing the second chamber 42) extends into the communication port 43, and the movable part (i.e., the float 20) is sealed and matched with the tail end of the mounting channel 21 when it moves to the direction of the first chamber 41 and reaches the position. Specifically, the tail end of the installation channel 21 is provided with a circle of second sealing flange 23 protruding toward the second chamber 42. When the movable part (i.e., the float 20) moves to the direction of the first chamber 41 and reaches the position, the second sealing gasket 40 provided on the float 20 abuts against the second sealing flange 23. The first sealing gasket 30 and the second sealing gasket 40 are both annular and made of rubber or silicone. The installation channel 21 can provide an upper limit for the middle of the float 20, reduce the uneven force on the middle and surrounding parts of the float 20 and reduce the deformation. In particular, the float 20 can be fitted with the water inlet channel 1 with a gap to ensure that the float 20 moves up and down smoothly. This is because, the installation channel 21 and the second sealing flange 23 thereon prevent water from entering the space outside the installation channel 21 of the first chamber 41 from the gap between the float 20 and the water inlet channel 1; if the installation channel 21 and the second sealing flange 23 thereon are not provided, and the movement of the float 20 is to be ensured to be relatively smooth, water will enter the first chamber 41 from the gap between the float 20 and the water inlet channel 1, thereby affecting the established water intake.

[0041] In this embodiment, the water storage body 10 includes a first shell 2, a second shell 3 and a water inlet channel 1. The first shell 2 and the second shell 3 are sealed and connected to form a water storage chamber 4. The water outlet 31 is provided in the second shell 3. The water inlet channel 1 is sealed and penetrated in the first shell 2, and one end of the water inlet channel 1 is located outside the first shell 2, and one end of the water inlet channel 1 extends through the water storage chamber 4 to the water outlet 31. Specifically, the first shell 2 and the second shell 3 are distributed up and down, and the bottom end of the first shell 2 is nested in the second shell 3, and the two can be fixed by ultrasonic welding. The above-mentioned installation channel 21 is provided in the first shell 2 and is threadedly connected to the water inlet channel 1, but the connection method between the installation channel 21 and the water inlet channel 1 is not limited to this.

[0042] In this embodiment, a reinforcing flange 33 is provided around the water outlet 31 inside the water storage chamber 4, which can strengthen the strength of the water outlet 31 of the water storage body 10. The reinforcing flange 33 is clearance-fitted with the other end of the water inlet channel 1, and the height of the reinforcing flange 33 is about 3 mm.

[0043] The pressure-stabilizing and boosting water storage device of the present invention can be used for flushing in toilets. When used, the water outlet 31 of the water storage body 10 is connected to a flush valve so that the flush valve controls whether the water outlet 31 is opened or not.

[0044] The working principle of the pressure-stabilizing and pressure-boosting water storage device of the present invention is as follows:

[0045] When water is inletting, the water outlet 31 is closed, and tap water flows in along the water inlet channel 1 and flows into the second chamber 42 of the water storage chamber 4 of the water storage body 10 from the water gap 32. Figure 7 As shown, the arrow in the figure indicates the direction of water flow, so that the water level in the second chamber 42 gradually rises, and compresses the air in the water storage chamber 4, thereby storing air pressure energy. As the water level in the second chamber 42 continues to rise, the float 20 gradually rises due to the buoyancy. When the float 20 rises to the highest position (i.e., the junction of the first chamber 41 and the second chamber 42), the connecting port 43 will be closed, so that water cannot enter the upper space of the water storage chamber 4 (i.e., the first chamber 41), thereby ensuring that the maximum air pressure of the air above the second chamber 42 does not exceed the set value (i.e., less than or equal to 0.1MPa), thereby avoiding the risk of explosion of the water storage body 10. Therefore, after the float 20 rises to the right position, the water inlet channel 1 automatically stops feeding water into the water storage chamber 4.

[0046] When flushing, the flush valve is opened, and the water in the water storage body 10 and the tap water are discharged from the water outlet 31 at the same time, forming a flushing force. Figure 8 As shown in the figure, the solid arrow indicates the direction of water flow. Since the other end of the water inlet channel 1 is located in the wider water outlet 31, an ejector structure can be formed, so that when the water outlet 31 is open, when the tap water flows to the water outlet 31, a negative pressure will be formed at the water gap 32, thereby attracting the water in the second chamber 42 to flow to the water outlet 31. Therefore, the water in the water storage chamber 4 will be compressed by the pressure of the compressed air (such as Figure 8 As shown in the figure, the dotted arrow in the figure indicates the direction of the pressure of the compressed air), the water is quickly drained under the combined action of the water's own gravity and negative pressure, so that the amount of water discharged in a short time by the present invention is greater than the amount of water generated when the tap water and the water storage body 10 simply form a parallel waterway, thereby greatly increasing the drainage flow rate and improving the flushing effect. In addition, the present invention can stabilize the drainage pressure by increasing the flow and pressure when the tap water pressure is low and the flow rate is small, thereby playing a role in stabilizing the pressure, thereby solving the problem of insufficient flushing force and flushing water volume and poor flushing effect when the tap water pressure is low and the flow rate is small in the prior art.

Specifically, in the present embodiment, the water outlet of the flushing valve is connected to the jet waterway of the toilet body; the present invention also comprises a water inlet valve, the water inlet of the water inlet valve is connected to the tap water pipeline, the water inlet valve has a first water outlet and a second water outlet switchedly connected to the water inlet, the first water outlet of the water inlet valve is connected to the brush ring waterway of the toilet body, and the second water outlet of the water inlet valve is connected to the water inlet of the water inlet channel 1.
