Description

Technical Field

[0001] This utility model relates to the field of flushing valve technology, and specifically to an automatic flushing valve. Background Technology

[0002] A flushing valve is a type of valve used to control fluid flow. Flushing valves are widely used in various applications where fluid flow control is required, such as water dispensers, water purifiers, coffee machines, medical devices, and industrial automation equipment.

[0003] During the use of water dispensers, stagnant water in the pipes can provide conditions for the formation of biofilms. To prevent biofilm formation, users often need to manually flush the pipes to keep the drinking water flowing. In actual use, when users go out or do not use the water for a long time, they need to drain the residual water in the pipes in advance, which increases the inconvenience of using the water dispenser. Therefore, an automatic flushing valve is proposed. Utility Model Content

[0027] like Figures 1 to 4As shown, an automatic flushing valve includes: a fixed housing 1, which is open on one side and has a top cover 101 at the open end; a flushing mechanism, disposed inside the fixed housing 1, for discharging water from the pipeline, the flushing mechanism including a guide member 3 and a control member 4, the guide member 3 being disposed inside the fixed housing 1 for guiding water, and the control member 4 being disposed inside the guide member 3 for controlling the flow direction of the water, and the guide member 3 cooperating with the control member 4 to flush the inner wall of the pipeline; and a water pump 2, disposed outside the guide member 3, for pumping water from the pipeline, specifically, when it is necessary to flush... When cleaning the liquid inside the pipeline, the liquid inside the pipeline is first pumped out by the water pump 2 through the cooperation of the flow guide 3 and the control component 4, so as to avoid the liquid remaining inside the pipeline and causing impurities to adhere to the inner wall of the pipeline. After the liquid is cleaned, the channel between the pipeline and the water pump 2 is closed again through the cooperation of the flow guide 3 and the control component 4 to prevent liquid leakage during normal use. The fixed shell 1 and the top cover 101 can be connected by buckles or bolts, which facilitates the maintenance and replacement of the water pump 2, flow guide 3 and control component 4 inside the fixed shell 1 during use.

[0028] like Figures 1 to 4 As shown, the guide component 3 includes a fixed pipe 301, one end of which penetrates the fixed shell 1, and the other end of which is provided with a sealing cap 303. A drain pipe 302 and a connecting pipe 306 are respectively provided on the outside of the fixed pipe 301, and the drain pipe 302 and the connecting pipe 306 are connected to the fixed pipe 301. Specifically, the sealing cap 303 blocks the water flowing inside the fixed pipe 301 to ensure that the water can flow stably. A water pipe is connected to the outside of the drain pipe 302, so as to guide the water entering the fixed pipe 301 during use. One end of the fixed pipe 301 is connected to the water inlet pipe. The fixed pipe 301 and the sealing cap 303 can be connected by threads or snaps. A sealing ring is also provided between the drain pipe 302 and the fixed pipe 301 to prevent water inside the fixed pipe 301 from seeping through the gap between the sealing cap 303 and the fixed pipe 301.

[0029] like Figures 1 to 4As shown, the water pump 2 is connected to the fixed housing 1. The water pump 2 is also provided with an outlet pipe 201 on the outside.

Specifically, during use, the sliding rod 401 and the baffles 403 cooperate to control the connection between the fixed pipe 301, the drain pipe 302, the connecting pipe 306, and the fixed pipe 301. The connection of the fixed pipe 301 is controlled to cooperate with the water pump 2 to stably flush the inner wall of the water pipe. The sealing ring 404 can be made of rubber or silicone. The sealing ring 404 seals the gap between the baffle 403 and the fixed pipe 301 to prevent water from seeping through the gap between the baffle 403 and the fixed pipe 301. During the movement of the baffle 403, there are no restrictions on the shape of the sliding rod 401. It can be cylindrical or hexagonal prism, etc. The sliding rod 401 guides the movement direction of the baffle 403 to ensure the stability of the movement direction of the baffle 403.

The driving component 304 is connected to the sealing cover 303. Specifically, the driving component 304 can be an electromagnetic push rod or an electric telescopic rod. The driving component 304 and the connecting rod 305 are connected by a fixing plate. The connecting rod 305 and the sliding rod 401 can be connected by threads or snaps to ensure that the driving component 304 can stably drive the sliding rod 401 and the baffle 403 to move in position during use. The driving component 304 can be controlled by the control module during use. The control module can control the driving component 304 during use to realize timed flushing of the water pipe. The control module can control the flushing time and flushing frequency. The control module is existing technology and will not be explained in detail here.

[0032] like Figures 1 to 4 As shown, a spring 402 is also sleeved on the outside of the sliding rod 401, and the spring 402 is located between the sealing cover 303 and the baffle 403. Specifically, the sliding rod 401 can provide tension to the sealing ring 404 during use, so as to ensure the stability of the sealing ring 404 relative to the fixed tube 301 during use.
