Description

Technical Field

[0001] The utility model relates to the technical field of flush valves, in particular to an intelligent mechanical one-piece flush valve. Background Art

[0002] A flush valve is a device used to control water flow, which is widely used in various bathroom equipment, such as toilets, squat toilets, urinals, etc. Its main function is to control the switch of the water source so that the water source can be turned off in time after use, so as to save water and keep the bathroom clean. There are many types of flush valves, which can be divided into many types according to different usage occasions and needs. Among them, the common ones include mechanical flush valves, induction flush valves, and foot-operated flush valves. Mechanical flush valves need to be operated manually and are suitable for some simple bathroom equipment; induction flush valves can automatically control the switch of water flow through sensors, which is suitable for some public places or occasions that require automatic control; foot-operated flush valves need to be stepped on to control the switch of water flow, which is suitable for some occasions that need to avoid hand contact.

[0003] For example, the Chinese patent "CN218597291 U" discloses a mechanical magnetic flushing valve component for a toilet, which proposes that: both sides of the top of the valve body are connected with valve covers by bolts, and the valve covers are provided with connecting pipe openings on the sides facing the center line, and the connecting pipe openings of the valve covers are connected to the mechanical valve through large and small sleeves, and a turntable is provided on the middle of the mechanical valve. The rotation of the mechanical valve turntable drives the magnet to rotate, and the magnet rotates and sequentially absorbs two magnetic cores. The device is applied to the flushing control component of the toilet. The rotation of the mechanical valve turntable drives the magnet to rotate, and the magnet rotates and sequentially absorbs the two magnetic cores, so that the magnetic core no longer blocks the pressure relief pipe, so that the integrated valve body can achieve the flushing effect. Since the drainage holes on both sides of the valve body are respectively connected to the upper flushing pipe and the lower flushing pipe of the toilet, the device can realize the upper and lower flushing of the toilet.

[0004] It can be seen from the above-mentioned device that although an effective method for flushing water by opening the valve core through the magnetic force of a magnet is proposed, the current technical solution still has the following shortcomings:

[0005] The existing flush valve cannot adjust the flushing volume freely during use, which may cause water waste or incomplete flushing. It is also cumbersome to adjust the flushing volume. In addition, flushing can only be performed when the power is off or the power is off, and the flushing cannot be performed, affecting normal use. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies in the prior art, the utility model provides an intelligent mechanical one-piece flush valve, which has the advantages of simple overall structure and convenient operation. The opening and closing of the valve core can be controlled by the air pressure of the air pump in the cavity to freely control the amount of water output. This solves the problem that the flushing volume of the existing flush valve cannot be freely adjusted during use, which may cause waste of water or incomplete flushing during flushing, and is also relatively cumbersome to adjust the flushing water volume. In addition, flushing can only be performed by relying on power supply. Flushing cannot be performed during power outages or power outages, affecting normal use.

[0020] Beneficial effects:

[0021] 1. The intelligent mechanical one-piece flush valve is equipped with intelligent components, so that the amount of water output and the water pressure can be adjusted by setting the pumping time of the vacuum pump, which effectively avoids the problem of water waste caused by unclear flushing or long flushing time and large water volume.

[0022] 2. The intelligent mechanical one-piece flush valve, through the cooperation between the vacuum pump and the cavity, evacuates the air inside the cavity when the vacuum pump is started. Since the valve core and the cavity are in a sealed connection, the valve core descends due to the influence of negative pressure when the cavity is evacuated, thereby opening the valve for flushing.

[0023] 3. The intelligent mechanical one-piece flush valve is provided with a reset spring, so that when the user manually presses the button to open the valve and the vacuum pump is evacuated, the reset spring elastically supports the valve core to ensure that it can return to its initial position and be tightly closed.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-2 The intelligent mechanical one-piece flush valve comprises a valve body 1, a connector 13 is provided on the top of the valve body 1, a valve core assembly 2 is provided outside the connector 13, and the valve core assembly 2 is a key part of controlling the water flow switch. The opening and closing of the valve core 27 determines whether water can flow from the water inlet to the water outlet. A limit tube 14 is provided below the valve body 1, a bottom cover 15 is movably installed on the outer wall of the limit tube 14, and an intelligent component 3 is provided on the outer wall of the bottom cover 15. A water inlet 11 is provided on one side of the valve body 1, and a water outlet 12 is provided on the other side of the valve body 1. An upper partition 16 is provided above the inner wall of the valve body 1, a lower partition 17 is provided below the inner wall of the valve body 1, and a baffle 18 is provided on the inner wall of the valve body 1 near the water outlet 12.

[0032] See also Figure 3-4The valve core assembly 2 includes a button 21. The user operates the valve core assembly by pressing the button 21 to control the switch of the water flow. A mounting groove 22 is provided inside the button 21. A valve stem 23 is mounted on the mounting groove 22 through internal thread engagement. The valve stem 23 penetrates into the interior of the valve body 1. A connecting plate 25 is fixedly connected below the valve stem 23. A valve core 27 is fixedly connected to the outer wall of the connecting plate 25. When the valve core 27 is in a closed state, it will fit tightly on the baffle 18 and the upper partition 16 or the lower partition 17 to prevent water from passing through. When the valve core 27 is in an open state, it will move away to allow water to pass through. A cavity is formed from the bottom of the valve core 27 to the inner wall of the bottom cover 15. The button 21 is movably mounted on the outer wall of the connector 13. The valve stem 23 is movably mounted inside the connector 13. A sealing member is filled between the interior of the connector 13 and the valve stem 23. The sealing member filled between the interior of the connector 13 and the valve stem 23 is used to ensure that the valve stem 2 3 will not leak water when moving, and the sealing of the valve is maintained. A return spring 24 is sleeved on the outer wall of the valve stem 23. The upper end of the return spring 24 is fixedly connected to the inner wall of the button 21, and the lower end of the return spring 24 is fixedly connected to the connector 13. When the button 21 is released, the return spring 24 will push the button 21 and the valve stem 23 back to the initial position to ensure that the valve core 27 can be tightly closed. An upper sealing ring 26 is sleeved on the upper edge of the outer wall of the valve core 27. The upper sealing ring 26 is sealed against the outer wall of the upper partition 16 and the baffle 18 in the closed state. A lower sealing ring 28 is arranged on the lower edge of the outer wall of the valve core 27. The lower sealing ring 28 is sealed against the outer wall of the lower partition 17 and the baffle 18. The upper sealing ring 26 and the lower sealing ring 28, which are sleeved on the upper and lower edges of the outer wall of the valve core 27 respectively, are used to enhance the sealing between the valve core 27 and the partition. When the valve core 27 is closed, these sealing rings will be tightly fitted on the outer wall of the partition to prevent water from flowing through.

[0033] See also Figure 3-4 The intelligent component 3 includes a vacuum pump 31. The vacuum pump is the core component of the intelligent component. It is responsible for generating negative pressure or positive pressure airflow. The vacuum pump 31 is fixedly installed on the outer wall of the bottom cover 15. The output end of the vacuum pump 31 is fixedly connected to an air pipe 32. The air pipe 32 is sealed and connected to the inside of the bottom cover 15. The air pipe 32 is used to transmit airflow. It is sealed and connected to the inside of the bottom cover to ensure that the airflow does not leak. The vacuum pump 31 is connected to the automatic sensing device of the toilet. The automatic sensing device controls the vacuum pump 31 to start after sensing that someone has finished using the toilet. The automatic sensing device is a part of the toilet and is usually installed on the seat or cover of the toilet. It can sense human movements or presence. For example, when someone leaves the toilet after using the toilet, the automatic sensing device will send a signal to the vacuum pump 31 in the intelligent component 3. This signal tells the vacuum pump to start working. After receiving the signal, the vacuum pump 31 will start and start working. Depending on the design of the vacuum pump, it may generate negative pressure or positive pressure airflow, which is transmitted to the inside of the bottom cover 15 through the air pipe 32.

[0034] Working principle: First, after the flush valve is installed, when the automatic sensing device senses that someone has finished using the toilet, it will send a signal to the vacuum pump 31 in the smart component 3. After receiving the signal, the vacuum pump 31 will start and extract air into the cavity inside the bottom cover 15 through the air pipe 32. Since the valve core 27 is sealed and connected with the lower partition 17 and the baffle 18 through the lower sealing ring 28, when the vacuum pump 31 is evacuated, the valve core 27 moves toward the bottom cover 15 below. After the valve core 27 moves downward, the upper sealing ring 26 and the upper partition 16 are no longer sealed, and the valve core 27 moves to the position below the baffle 18. Water flows through the gap between the baffle 18 and the valve body 1 to flush. The amount of flushing and the water pressure can be controlled by setting the evacuation time of the vacuum pump 31. The flushing is completed after the evacuation time ends.

[0035] Secondly, when the power is off or the power is off, the user can manually control the valve core assembly 2 by pressing the button 21. When the button 21 is pressed, the valve stem 23 and the valve core 27 will move downward to open the water flow channel. However, the return spring 24 ensures that after the button 21 is released, the valve core 27 can return to the initial position and close tightly.
