Description

Technical field:

[0001] The utility model relates to a water tank water inlet and drainage system, in particular to a water tank water inlet and drainage system in which a water tank water inlet valve of a dual independent control system and a hydraulic drainage valve with a pressure relief valve are used in coordination with each other. Background technology:

[0002] In bathroom products, the development of toilet technology has led to more requirements for water tank accessories. Traditional water tank inlet valves generally use a water stop control unit, which relies on a float to control the water inlet to the tank as the water level changes. However, with the diversification and intelligence of toilet designs, the functional requirements for water inlet valves are increasing, and a water stop control unit cannot meet these requirements. Traditional drain valves may not be able to stop the water immediately or the water stop surface may be flushed open after stopping, resulting in backflow. Furthermore, for products such as sunken toilets or smart toilets, the drain valve may be set in a sealed water tank to achieve a stronger flushing force when the water tank is flushed. In this case, using a traditional top-press drain valve or a wire-controlled drain valve will not meet the sealing requirements. Utility model content:

When the pressure relief valve 6' slides upward under the buoyancy force, the pressure relief plug 62' on it is inserted into the pressure relief hole 421' on the hydraulic body 41' and stops rising. At this time, the pressure relief hole 421' is in a closed state, and the liquid in the hydraulic body 41' cannot be depressurized. When the extension part 42' continues to introduce liquid, the hydraulic rod 431' will be subjected to the upward liquid pressure and move upward, thereby driving the sealing cover 51' and the water sealing plate 52' to move upward together, so that the hook 512' on the sealing cover 51' is hooked on the hanging platform 323' of the full-row float bucket bracket 32'.

[0065] The pressure relief valve 6' has pressure relief valve floats 63' on both sides of its upper portion and a pressure relief plug 62' in the middle of its lower portion. The pressure relief valve float 63' and the pressure relief plug 62' are connected by a connecting portion 64', and guide ribs 61' are provided on both sides of the connecting portion.

[0066] When the present invention is working, the water inlet valve A and the drain valve B are correctly installed in the water tank C, and the water inlet valve A is connected to the external water supply pipe so that the water tank C is filled with water. When flushing is needed, the second control unit 8 is actively triggered, and the second control unit 8 controls the second lifting rod 91 to rotate and compresses the second lifting rod spring 92, and the water stop pad 72 is opened (the water stop pad here is the water stop pad in the second water stop assembly 7). Water flows from the gap between the water stop pad 72 and the water stop surface 122 into the middle hole of the water stop surface 122, thereby entering the second water outlet channel 121 of the main body, and finally flows out from the second water outlet 32 ​​into the second water outlet pipe assembly 11, and finally introduced into the hydraulic body 41'. At this time, the extension part 42' on the hydraulic body is subjected to the driving liquid pressure of the second water outlet pipe assembly 11. Since the pressure relief hole 421' is in a closed state at this time, the driving liquid pressure acts on the hydraulic rod 431', so that The hydraulic rod 431' overcomes the elastic force of the spring 433' and the pressure of the water pressure in the water tank on the sealing cover 51' and their own gravity, so that the hydraulic rod 431' drives the sealing cover 51' to move upward until the hook 512' on the sealing cover 51' is hung on the hanging platform 323', and the drain valve is fully opened to achieve flushing. When the second control unit 8 is stopped from being triggered, the triggering of the control unit 8 is completed instantly, and the second lifting rod 91 is rotated in the opposite direction by the elastic force of the second lifting rod spring 92, and the water stop pad 72 is closed (the water stop pad here is the water stop pad in the second water stop assembly 7) to stop water discharge. The second control unit 8 is actively triggered, and its triggering method can be wire rope type or mechanical pressing. When the water level in the water tank starts to drop, when the water level in the water tank drops to a certain height, the pressure relief valve 6' starts to drop, and the pressure relief plug 62' on the pressure relief valve 6' is separated from the pressure relief hole 421' on the extension tube 42' of the hydraulic body, and the pressure relief hole 421' is in an open state. As the water level continues to drop, the entire row of float barrels 31' begins to drop, and drives the entire row of float barrel brackets 32' to rotate in the opposite direction. At this time, the hook 512' on the sealing cover 51' is separated from the hanging platform 323', and the hydraulic rod 431' and the sealing cover 51' fall downward rapidly under the elastic force of the spring 433' and their own gravity and close the drain valve. Since the pressure relief hole 421' is in an open state at this time, During the rapid drop of the hydraulic rod 431' and the sealing cover 51', the liquid in the hydraulic chamber 412' can be quickly discharged without affecting the rapid drop of the hydraulic rod 431' and the sealing cover 51'; as the water level in the water tank C continues to drop, the one-way valve 53 opens, and the inner float 52 drops as the water level drops, thereby driving the first lifting rod connecting arm 61 and the first lifting rod 62 to rotate, and the water stop pad opens (the water stop pad here is the water stop pad in the first water stop assembly 4), and water flows from the gap between the water stop pad and the water stop surface 112 into the middle hole of the water stop surface 112, thereby entering the first water outlet channel 111 of the main body 1, and finally entering the first water outlet assembly 10 from the first water outlet 31, and finally flowing out into the water tank C;When the water level in the water tank C rises, the full-row float bucket 31' rises and drives the full-row float bucket bracket 32' to rotate. As the water level continues to rise, the pressure relief valve 6' rises. At this time, the pressure relief plug 62' on the pressure relief valve 6' is inserted into the pressure relief hole 421' on the extension part 42' and stops rising. At this time, the pressure relief hole 421' is in a closed state. At the same time, as the water level in the water tank C rises, the inner float bucket 52 rises with the water level, thereby driving the first lifting rod connecting arm 62 and the first lifting rod 61 to rotate in the opposite direction, closing the water stop pad (here, the water stop pad is the water stop pad in the first water stop assembly 4) and stopping water discharge, completing the entire flushing and water inlet cycle. The up and down movement of the inner float bucket 52 is passive and changes accordingly with the up and down changes in the water level in the water tank.

[0067] It should be noted that no matter which position the adjusting plate 7' is adjusted to, the pressure relief valve 6' will drop earlier than the full discharge float 31' when the water level in the water tank drops.

[0068] The water inlet valve adopts a dual independent control system, which can provide two independent water outlet modes. In addition to the conventional passive trigger float control system, an active trigger control system is also provided that can be used for opening the drain valve, active and precise water replenishment, active flushing, etc. The active trigger control system can adopt a wire rope type, a mechanical press type, an air control type or an electric control type. If the active trigger control system is used to open the drain valve, the control system can be conveniently set at any position and is not restricted by the position of the drain valve. The two accommodating chambers are both provided on the main body and can be set at different angles. Although there is an additional control system compared to the traditional water inlet valve, the overall structure is compact, the external dimensions have not increased, and the installation is more convenient.

[0069] Compared with traditional drain valves, the drain valve has a more compact structure, a shorter height and higher adaptability; a pressure relief valve is provided on the extension part of the hydraulic body, which can make the drain valve close quickly to prevent backflow; in addition to the gravity of the sealing cover connected to it, the water sealing plate is also subjected to the pressure of the spring, which makes the water sealing plate have a higher sealing effect.

As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
