Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a coffee machine vent valve. Background Technology

[0002] Chinese Patent CN118499538A discloses a drain valve, comprising a valve body, a water outlet valve core assembly, a pressure relief valve core assembly, and an air vent valve core assembly. The valve body includes an inlet channel, an outlet channel, a pressure regulating chamber, and a return channel. An air vent is provided in the return channel, and the inlet of the return channel is connected to the outlet of the water flow channel via the air vent. A return pipe connector is installed at the outlet of the return channel. The air vent valve core assembly is installed within the return channel for opening and closing the return channel. The air vent valve core assembly includes a valve... The valve core includes a core seat and an umbrella-shaped valve core. The core seat is sealed within the return channel. A through hole is provided in the middle of the core seat. A flow groove extending radially from the through hole to the edge of the core seat is provided on the surface of the core seat facing the water flow direction. A flow hole is provided through the bottom wall of the flow groove. The umbrella-shaped valve core includes a rod that slides through the through hole and an elastic part. A limiting protrusion is provided on the peripheral wall of the rod. The limiting protrusion and the umbrella part are located at the two ends of the core seat, and the tail end of the rod extends into the inner cavity of the return pipe connector.

[0003] In the above structure, since the umbrella-shaped valve core is normally umbrella-shaped, it is easy for air to be discharged from the filter tank and the flow passage in the flow passage. Since the inside of the return pipe joint and the exhaust hole are connected to each other through the flow passage, and the end of the umbrella-shaped valve core near the valve core seat is blocked outside the filter hole, the exhaust efficiency of the umbrella-shaped valve core is low. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies where the internal part of the return pipe connector and the exhaust port are interconnected through a flow hole, and the end of the umbrella-shaped valve core near the valve core seat is blocked outside the filter hole, resulting in low exhaust efficiency of the umbrella-shaped valve core. This invention provides a coffee machine vent valve that can improve exhaust efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A coffee machine vent valve includes a vent valve body with a vent structure for venting and draining water. The vent structure includes a water inlet channel within the vent valve body, a normally open venting component that is normally open and closes when water flows into the water inlet channel, and a normally closed draining component that is normally closed and opens after water enters the water inlet channel. The normally closed draining component is disposed at a greater depth within the water inlet channel than the normally closed venting component is disposed at a greater depth within the water inlet channel.

[0007] Using the above scheme, the normally open venting component can expel the air inside the vent valve body, while the normally closed draining component can expel the water flowing into the inlet channel. At the same time, the normally closed draining component can also be opened by air pressure when the normally open draining component is closed, allowing the air inside the vent valve body to be discharged from the normally closed draining component. Since the normally open venting component is normally in the open state, it facilitates the discharge of air from the vent valve body. At the same time, the normally closed draining component can also be opened when the normally open venting component is closed, allowing the air to be discharged from the vent valve body, thereby improving the venting efficiency of the vent valve body.

[0008] Preferably, the normally open venting component includes an venting channel provided on the inner wall of the water inlet channel and a first opening / closing component for opening and closing the venting channel, wherein the first opening / closing component normally opens the venting channel.

[0009] Preferably, the first opening and closing component includes an opening and closing plug that is slidably disposed near the water inlet channel in the exhaust channel and a first elastic element that drives the opening and closing plug to open the exhaust channel in its normal state. A first connecting hole is provided on the water inlet channel at a misalignment with the exhaust channel for air intake and can push the opening and closing plug to close the exhaust channel after water flows into it. An air inlet hole is provided on the opening and closing plug that communicates with the first connecting hole. When the opening and closing plug is in the first position, the first connecting hole, the air inlet hole, and the exhaust channel are interconnected, and the opening and closing plug is in its normal state. When water flows into the first connecting hole, the water pushes the opening and closing plug to move to the second position, and the side wall of the opening and closing plug closes the exhaust channel.

[0010] Using the above scheme, when the first elastic element pushes the opening and closing plug to the first position, i.e., when the first elastic element is in its normal state, the side wall of the opening and closing plug is away from the exhaust channel. The first connecting hole, the air inlet, and the exhaust channel are interconnected. The air in the vent valve can flow from the first connecting hole into the air inlet and finally be discharged from the exhaust channel. When water flows into the first connecting hole, the water will gradually push the opening and closing plug towards the exhaust channel until the side wall of the opening and closing plug closes the exhaust channel. At this time, the water and the remaining air in the water inlet channel will flow into the normally closed drain component. The normally closed drain component will then gradually open and discharge from it.

[0011] Preferably, the first elastic element includes a first spring, which normally drives the opening and closing plug to open the exhaust passage.

[0012] Using the above scheme, the first spring can push the opening and closing plug to open the exhaust passage under normal conditions, thereby allowing the air in the vent valve body to be discharged from the exhaust passage.

[0013] Preferably, the normally closed drainage component includes a drainage channel located in the water inlet channel at a depth greater than that of the normally open venting component, and a second opening / closing component for opening and closing the drainage channel, wherein the second opening / closing component normally closes the drainage channel.

[0014] Preferably, the second opening and closing component includes a second connecting hole disposed in the water inlet channel and opposite to the exhaust channel, an umbrella-shaped plug for opening and closing the drainage channel, and a second elastic member that drives the umbrella-shaped plug to block the second connecting hole under normal conditions.

[0015] By adopting the above solution, the second elastic element can drive the umbrella-shaped plug to close the drainage channel under normal conditions, preventing air or water from entering the drainage channel. At the same time, the second elastic element can also push the umbrella-shaped plug to reset after the umbrella-shaped plug opens the drainage channel.

[0016] Preferably, the second elastic element includes a second spring, which normally drives the umbrella-shaped plug to close the exhaust channel.

[0017] Using the above scheme, the second spring can push the umbrella-shaped plug to close the exhaust channel under normal conditions, allowing the air in the vent valve body to be discharged from the normally open exhaust component. At the same time, the second spring can also push the umbrella-shaped plug to reset and close the drainage channel after the umbrella-shaped plug retracts to open the drainage channel.

[0018] This utility model, by adopting the above technical solutions, has significant technical effects: the normally open venting component can discharge the air inside the vent valve body, while the normally closed draining component can discharge the water flowing into the inlet channel. At the same time, the normally closed draining component can also be opened by air pressure when the normally open draining component is closed, so that the air inside the vent valve body can be discharged from the normally closed draining component. Since the normally open venting component is normally in the open state, it is convenient for air to be discharged from the inside of the vent valve body. At the same time, the normally closed draining component can also be opened when the normally open venting component is closed, so as to discharge the air from the vent valve body, thereby improving the venting efficiency of the vent valve body.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example

[0025] A coffee machine vent valve, reference Figures 1-3 The system includes a drain valve body 1, and a drain structure for venting and draining is provided inside the drain valve body 1. The drain structure includes an inlet channel 2 for water supply flow in the drain valve body 1, a normally open venting component that is normally open and closes when water flows into the inlet channel 2, and a normally closed draining component that is normally closed and opens after water enters the inlet channel 2. The depth of the normally closed draining component in the inlet channel 2 is greater than the depth of the normally closed venting component in the inlet channel 2.

[0026] The normally open venting component includes an venting channel 301 disposed on the inner wall of the water inlet channel 2 and a first opening / closing component for opening and closing the venting channel 301. The first opening / closing component normally opens the venting channel 301. The first opening / closing component includes an opening / closing plug 305 slidably disposed on the venting channel 301 near the water inlet channel 2 and a first elastic member that drives the opening / closing plug 305 to normally open the venting channel 301. A first elastic member is disposed on the water inlet channel 2 at a misalignment with the venting channel 301 for air intake, which can push the opening / closing plug 305 to close the venting channel 301 after water flows into it. The connecting hole 302 has an air inlet 303 that communicates with the first connecting hole 302 on the opening and closing plug 305. When the opening and closing plug 305 is in the first position, the first connecting hole 302, the air inlet 303, and the exhaust channel 301 are interconnected, and the opening and closing plug 305 is in the normal state. When water flows into the first connecting hole 302, the water pushes the opening and closing plug 305 to move to the second position, and the side wall of the opening and closing plug 305 closes the exhaust channel 301. The first elastic element includes a first spring 304. Under normal conditions, the first spring 304 drives the opening and closing plug 305 to open the exhaust channel 301.

[0027] The normally closed drainage component includes a drainage channel 401 located in the water inlet channel 2 at a depth greater than that of the normally open venting component, and a second opening / closing component for opening and closing the drainage channel 401. The second opening / closing component normally closes the drainage channel 401. The second opening / closing component includes a second connecting hole 402 located in the water inlet channel 2 opposite to the venting channel 301, an umbrella-shaped plug 403 for opening and closing the drainage channel 401, and a second elastic member that drives the umbrella-shaped plug 403 to block the second connecting hole 402 in normal operation. The second elastic member includes a second spring 404, which drives the umbrella-shaped plug 403 to close the venting channel 301 in normal operation.

[0028] The specific venting process is as follows: When water flows into the inlet channel 2, the air in the inlet channel 2 gradually enters the first connecting hole 302, and then flows from the first connecting hole 302 into the air inlet hole 303 on the opening and closing plug 305. Since the first spring 304 normally pushes the opening and closing plug 305 to open the exhaust channel 301, the air flowing into the air inlet hole 303 gradually flows into the exhaust channel 301. When the water in the inlet channel 2 flows into the first connecting hole 302, the water will push the opening and closing plug 305 to move. At this time, the opening and closing plug... When the side wall of the blockage 305 is closed, the exhaust channel 301 will be sealed. When the water continues to flow into the inlet channel 2, the umbrella-shaped plug 403 set in the inlet channel 2 will move under the influence of air pressure. At this time, the inlet channel 2 will gradually open, and air will gradually enter the inlet channel 2 and be discharged from the inlet channel 2. When the water flows into the second connecting hole 402, the umbrella-shaped plug 403 will be displaced and open the drain channel 401, so the water will gradually flow into the drain channel 401 and be discharged from the drain channel 401.

All technical solutions falling within the scope of this utility model's concept are protected.
