An accumulator and a toilet flushing system with the accumulator

technical field

The invention relates to an accumulator and a toilet flushing system with the accumulator.

Background technique

As is known to all, in the existing toilet flushing system, the higher the water pressure and the more water volume of the flushing water, the more clean the toilet can be. In order to reduce the overall volume of the toilet, there is a market that directly uses the water flow from the tap to flush the toilet. However, when the water pressure of the tap water is insufficient, the flushing force and water volume of the water flow are insufficient, resulting in an unclean toilet. In order to effectively flush the toilet even when the water pressure of the tap water is insufficient, a method of pressurizing the tap water with a pump device has appeared on the market to increase the water pressure of the water flow, but the cost of using a pump device is high, and The pump device needs to be powered, which is troublesome. Alternatively, there are also energy storage components such as airbags on the market for energy storage and pressurization, but the energy storage components are always in a state of energy storage and pressure retention when they are in use, and the energy storage is released when the toilet is flushed to realize the flushing water. Pressurization, because its energy storage components are basically in the state of energy storage and pressure retention, the energy storage components are in a state of pressure for a long time when they are to be used, which is easy to damage and affects the service life of the product.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention provides an energy storage device, which can store energy and pressurize the water flow, has a simple structure and reliable function, and can avoid the energy storage component being in the state of energy storage and pressure maintenance for a long time when it is to be used. The problem that the functional components are easily damaged. The invention also provides a toilet flushing system with an accumulator, which can increase the water pressure of flushing water through the energy storage and pressurization of the accumulator, thereby greatly improving the flushing effect of the toilet.

An energy storage device comprises a main body with an energy storage cavity and an energy storage assembly arranged in the energy storage cavity, the main body also has a water inlet and a water outlet communicated with the energy storage cavity, and the water inlet and outlet are connected to the energy storage cavity. The water inlet of the water inlet flows into the energy storage cavity and is stored in the energy storage cavity, so that the energy storage component stores energy. When the water intake reaches a predetermined water inflow amount, the energy storage component automatically releases the energy storage. The water in the energy storage cavity is caused to flow out from the water outlet together with the inlet water.

According to the energy storage device of the present invention, when the water inlet starts to enter water, the water flow in the water inlet is first stored in the energy storage cavity of the energy storage device and enables the energy storage component to store energy. After a predetermined amount, the energy storage component automatically releases the energy storage, and makes the water in the energy storage cavity flow out from the water outlet together with the water in the water inlet, increasing the pressure and flow of the water flow out of the water outlet, thereby realizing the control of the water flow. For energy storage and pressurization, the structure is simple, the design is ingenious, and the function is reliable. In addition, because the energy storage component stores energy only during use and automatically releases the energy storage after the energy storage is sufficient, it can avoid the energy storage component being easily damaged due to the long-term storage pressure state when the energy storage component is to be used. The problem.

Preferably, the main body is further provided with a main valve port for connecting the energy storage cavity and the water outlet; the energy storage device further includes a main control valve, and the main control valve includes a main control valve movably arranged in the main body a main valve core matched with the main valve port; the energy storage component is an elastic energy storage component movably arranged in the energy storage cavity;

When the water inlet is not filled with water, the main valve core closes the main valve port; when the water inlet is filled with water, the water flow overcomes the elastic force of the elastic energy storage component and flows into the energy storage cavity and drives The elastic energy storage component enables the elastic energy storage component to store energy, and when the water intake reaches the predetermined water inflow amount so that the elastic energy storage component moves to a predetermined position, the main valve core opens the main valve core. The valve port, and then the water in the energy storage chamber is discharged from the main valve port under the action of the elastic energy storage component and flows out of the water outlet together with the water in the water inlet.

In the above scheme, by setting the main valve port and the main control valve, and the energy storage component is an elastic energy storage component, the main valve port is closed by the main valve core of the main control valve, so that when the water starts to enter, the water will not flow from the water outlet. Outflow, the water flow can be stored in the energy storage cavity and can promote the elastic energy storage component to store energy. When the water intake reaches a predetermined water intake, the elastic energy storage component moves to a predetermined position, and the main valve core opens the main valve port, so that the water in the energy storage cavity can be under the action of the elastic energy storage component.

Also, for example, the term "first element" does not by itself imply the presence of a "second element," nor does the term "second element" by itself imply the presence of a "first element."

Please refer to FIG. 1 to FIG. 9 , an energy storage device according to a preferred embodiment of the present invention includes a main body 10 , a main control valve 20 , an energy storage assembly, a secondary control valve 40 , and a transmission mechanism 50 .

The body 10 has a water inlet 11 , a water outlet 12 and an energy storage cavity 13 , and the water inlet 11 and the water outlet 12 communicate with the energy storage cavity 13 . The incoming water from the water inlet 11 flows into the energy storage cavity 13 and is stored in the energy storage cavity 13 to enable the energy storage component to store energy. When the inflow water reaches a predetermined amount of water inflow, the energy storage component automatically releases the energy storage, so that the energy storage cavity The water in 13 flows out of the water outlet 12 together with the inlet water.

In this embodiment, the body 10 is further provided with an overflow channel 14 for connecting the water inlet 11 and the water outlet 12 , and a main valve port 15 for connecting the energy storage cavity 13 and the water outlet 12 . The main control valve 20 includes a main valve core 21 movably arranged in the main body 10 and matched with the main valve port 15 . The energy storage component is an elastic energy storage component 30 , and the elastic energy storage component 30 is movably arranged in the energy storage cavity 13 .

When the water inlet 11 is not filled with water, the main valve core 21 closes the main valve port 15, and the overflow channel 14 is in a closed state. When water enters the water inlet 11 , the water flow overcomes the elastic force of the elastic energy storage component 30 and flows into the energy storage cavity 13 and drives the elastic energy storage component 30 so that the elastic energy storage component 30 stores energy. When the water intake of the water inlet 11 reaches a predetermined water intake, so that the elastic energy storage assembly 30 moves to a predetermined position, the overflow channel 14 is opened, so that the side of the main valve core 21 facing away from the energy storage cavity 13 is subjected to the action of water pressure The main valve port 15 is opened, and then the water in the energy storage chamber 13 is discharged from the main valve port 15 under the action of the elastic energy storage assembly 30 and flows out from the water outlet 12 together with the water in the water inlet 11, so that the water in the energy storage chamber 13 can flow out. The water flow pressure and water flow rate of the nozzle 12 are effectively improved.

Specifically, please refer to FIG. 8 and FIG. 9 , in this embodiment, a water inlet channel 17 and a water outlet channel 18 are formed on the main body 10a. The water inlet 11 forms the water inlet end of the water inlet channel 17, the water outlet end of the water inlet channel 17 is divided into a first water outlet end 171 and a second water outlet end 172, the first water outlet end 171 is communicated with the energy storage cavity 13, and the water inlet 11 Communication with the energy storage cavity 13 is achieved through the water inlet channel 17 and the first water outlet end 171 . The second water outlet 172 communicates with the overflow channel 14 , and the water inlet 11 communicates with the overflow channel 14 through the water inlet channel 17 and the second water outlet 172 . The water outlet 12 forms the water outlet end of the water outlet channel 18, and the water inlet end of the water outlet channel 18 communicates with the water outlet cavity 16 described below.

In this embodiment, when the water inlet 11 is not filled with water, the elastic energy storage assembly 30 abuts the main valve core 21 so that the main valve core 21 closes the main valve port 15; when the water inlet 11 is filled with water, the elastic energy storage assembly 30 is not When moving to a predetermined position, the main valve core 21 keeps closing the main valve port 15 under the action of water pressure, so that the main valve core 21 can close the main valve port 15 during the water storage process of the accumulator, thereby avoiding entering the energy storage. The water flow in the cavity 13 flows out from the main valve port 15 .

Please refer to FIG. 1 , FIG. 3 , FIG. 4 and FIG. 5 , in this embodiment, when the elastic energy storage component 30 is in contact with the main valve core 21 , there is a water flow gap between the elastic energy storage component 30 and the main valve core 21 , thereby The side of the main valve core 21 facing the elastic energy storage assembly 30 can be subjected to the force of water pressure. By setting the water flow gap, on the one hand, the water flow can flow to the side of the main spool 21 facing the elastic energy storage assembly 30 to apply water pressure to the main spool 21 so that the main spool 21 flows downward under the action of the water inlet pressure. The direction of closing the main valve port 15 is moved to close the main valve port 15; on the other hand, the elastic energy storage component 30 is prevented from abutting with the main valve core 21. When the elastic energy storage component 30 moves under the action of water pressure, the main valve The core 21 attracts and moves together in a direction away from the main valve port 15 , thereby causing the problem that the main valve core 21 cannot close the main valve port 15 during the process of storing water in the accumulator.

Connected to the main valve core 21, the protrusion 3111 is located between the piston head 311 and the main valve core 21, thereby forming the water flow gap therebetween.

When the overflow passage 14 is opened, the way to automatically open the main valve port 15 by the main valve core 21 can be designed as required. Alternatively, the main valve core 21 opens the main valve port 15 or the like under the action of its own gravity. Specifically, when the overflow channel 14 is opened, the side of the main valve core 21 facing away from the energy storage chamber 13 is subjected to water pressure. When the valve core 21 is under the water pressure on the side of the energy storage chamber 13 , the main valve core 21 can automatically open the main valve port 15 by the external force acting on the main valve core 21 or by its own gravity. The specific manner for the main valve core 21 to open the main valve port 15 can be designed as required, and is not limited to the above-mentioned embodiments.

Specifically, in this embodiment, the main control valve 20 includes a first elastic member 22 acting on the main valve core 21 , and the main valve core 21 overcomes the elastic force of the first elastic member 22 in the process of closing the main valve port 15 , that is, When the main valve core 21 closes the main valve port 15, the first elastic member 22 is in an elastic deformation state and exerts an elastic force on the main valve core 21. Of course, at this time, the elastic force exerted by the first elastic member 22 on the main valve core 21 is less than The water inlet pressure of the energy device 13 side to the main valve core 21, so as to ensure that the main valve core 21 keeps closing the main valve port 15 under the action of the water inlet water pressure. When the overflow channel 14 is opened, the resultant force of the elastic force exerted by the first elastic member 22 on the main spool 21 and the water pressure on the side of the main spool 21 facing away from the accumulator 13 is greater than that when the main spool 21 is located in the accumulator. The main valve core 21 opens the main valve port 15 under the action of the external force provided by the first elastic member 22 due to the water pressure on one side of the 13 . The main valve core 21 automatically opens the main valve port 15 by the elastic external force provided by the first elastic member 22, which is more reliable.

In this embodiment, the elastic energy storage assembly 30 includes a piston 31 and a second elastic member 32 acting on the piston 31. The piston 31 includes a piston head 311 and a piston rod 312.

The piston head 311 seals and isolates the energy storage cavity 13 into a first cavity 131 and a second cavity 132 . The first cavity 131 communicates with the water inlet 11 and the main valve port 15 , and the second cavity 132 communicates with the outside world.

In this embodiment, a secondary control valve 40 for controlling the opening and closing of the overflow passage 14 is also included. There are various ways to control the opening of the auxiliary control valve 40, including mechanical opening or electronically controlled opening. For example, when the elastic energy storage assembly 30 moves to the predetermined position, the auxiliary control valve 40 is opened by transmission, and the mechanical transmission control is adopted at this time. Open the secondary control valve 40, or the accumulator further includes a position sensor (not shown), when the position sensor senses that the elastic energy storage assembly 30 moves to the predetermined position, the position sensor controls the The auxiliary control valve 40 is opened. At this time, the auxiliary control valve 40 adopts an electronically controlled valve, or the accumulator further includes a flow sensor (not shown). When the flow sensor senses that the water inlet 11 flows into the When the water volume of the energy storage chamber 13 reaches a predetermined value, the flow sensor controls the auxiliary control valve 40 to open, and at this time, the auxiliary control valve 40 adopts an electric control valve. By setting the auxiliary control valve 40 to control the opening and closing of the overflow channel 14, the design is ingenious and the function is reliable. Of course, in addition to using the auxiliary control valve 40 to control the opening and closing of the overflow channel 14, there are other ways to realize the elastic energy storage assembly 30.

In this way, when the water pressure of the water inlet 11 is sufficient to overcome the elastic force of the fourth elastic member 42, the auxiliary valve port 141 can be opened under the action of the water inlet pressure, so that the water can flow out from the water outlet 12 without storing energy. Can be advanced, the effect is better.

Some guide rods 211 (the guide rods 211 are used to guide the up and down movement of the main valve core 21 ) extend upward from the main valve port 15 to the water outlet cavity 16 , and the bottom cover 10c is connected to the opening, so as to store energy. The assembly of the device is more convenient and the assembly efficiency is improved.

In this embodiment, the first elastic member 22 , the second elastic member 32 and the fourth elastic member 42 all use compression springs. Moreover, the elastic force of the second elastic member 32 is greater than that of the first elastic member 22 , and the elastic force exerted by the fourth elastic member 42 on the auxiliary valve core 41 is greater than the water pressure of the water inlet flow of the water inlet 11 to the auxiliary valve core 41 .

When in use, in the initial state, the water inlet 11 does not enter the water, at this time, the main valve core 21 closes the main valve port 15, and the overflow channel 14 is in a closed state. Please refer to FIG. 3 to FIG. 5 , when the water inlet 11 starts to enter water, the water flow overcomes the elastic force of the elastic energy storage component 30 and flows into the energy storage cavity 13 , and the main valve core 21 is under the action of the water pressure in the energy storage cavity 13 . The main valve port 15 is kept closed against the elastic force of the first elastic member 22 . As the water flow continuously enters the energy storage cavity 13 , the water flow drives the elastic energy storage assembly 30 so that the piston 31 of the elastic energy storage assembly 30 moves downward and compresses the second elastic member 32 to store energy. During this process, the auxiliary valve core 41 of the auxiliary control valve 40 keeps closing the auxiliary valve port 141 under the action of the elastic force of the fourth elastic member 42 (at this time, the elastic force of the fourth elastic member 42 to the auxiliary valve core 41 is greater than that of the water flow In response to the water pressure of the secondary valve core 41 ), the overflow channel 14 remains closed, so that the water flow from the water inlet 11 cannot flow to the water outlet 12 through the overflow channel 14 .

Please continue to refer to FIG. 6 , when the elastic energy storage assembly 30 moves to a predetermined position, the piston head 311 of the elastic energy storage assembly 30 begins to abut one end of the swing rod 51 of the transmission mechanism 50 downward (ie, the left end in FIG. 6 ), Thus, the swing rod 51 is driven to swing, and the other end of the swing rod 51 (ie, the right end in FIG. 6 ) moves upward and drives the auxiliary valve core 41 to overcome the force of the fourth elastic member 42 through the push rod 52 to move upward, and the auxiliary valve core 41 moves upward. After the movement, the auxiliary valve port 141 is opened, thereby opening the flow passage 14 , so that the water flow of the water inlet 11 can flow into the water outlet cavity 16 through the flow passage 14 .

When there is water flow in the water outlet chamber 16, the side of the main valve core 21 facing away from the energy storage chamber 13 is subjected to water pressure. At this time, the elastic force exerted by the first elastic member 22 on the main valve core 21 and the main valve core 21 The resultant force of the water pressure on the side facing away from the energy storage chamber 13 is greater than the water pressure on the side of the main spool 21 on the side of the energy storage 13. Taking the direction of FIG. 6 as an example, the main spool 21 moves downward and opens the main valve At this time, the water in the energy storage chamber 13 is discharged from the main valve port 15 under the action of the elastic energy storage assembly 30 and flows out from the water outlet 12 together with the water in the water inlet 11, so that the water flowing out of the water outlet 12 The water flow pressure and flow rate are effectively improved, so as to realize the energy storage and pressurization of the water flow.

After the water in the energy storage chamber 13 is discharged, since the elastic force of the second elastic member 32 is greater than that of the first elastic member 22, the elastic energy storage assembly 30 pushes against the main valve core 21 again, so that the main valve core 21 can overcome the first elastic force The elastic force of an elastic member 22 is positioned to close the main valve port 15 . At the same time, after the elastic energy storage assembly 30 is reset, it loses contact with the swing rod 51 of the transmission mechanism 50, and the auxiliary valve core 41 is reset under the action of the fourth elastic member and closes the auxiliary valve port 141, so that the energy storage device restore to the original state.

Among them, the arrows in FIGS. 2 to 6 indicate the flow direction of the water.
