Description

Technical Field

[0001] This utility model relates to the field of pipeline control valve technology, and in particular to a water-passing one-way valve assembly that can be quickly disassembled and assembled. Background Technology

[0002] Current water dispensers, coffee makers, and beverage dispensers are typically used far from water sources, and therefore are equipped with water tanks or buckets as water storage units. The water tank's outlet is equipped with a one-way valve. When the water tank is installed on the dispenser, the one-way valve opens the outlet, allowing water to flow from the tank to the water-using unit within the dispenser. When the water tank is removed, the one-way valve closes, facilitating the movement of the tank for refilling or cleaning.

[0003] Chinese patent CN203407919U discloses a valve assembly for connecting a water tank and a pipeline in a water dispenser. The water tank has an outlet at its lower end, and the water dispenser has a tank seat for mounting the water tank. The tank seat has a socket hole that matches the outlet. The valve assembly includes: a first valve core, which is movably fitted into the outlet, and a sealing ring matching the outlet is installed on the upper end of the first valve core, as well as a first return spring; and a second valve core, which is movably fitted into the socket hole, and a limiting part is provided at the lower end of the second valve core, as well as a second return spring.

[0004] The drawback of the aforementioned prior art is that the valve assembly is integrated separately into the outlet of the water tank and the socket of the water tank seat. The water tanks must be fitted in pairs into the sockets of the water tank seat, and their positional relationship is unique. However, when some water-using equipment requires two or more water tanks to expand the water storage capacity, the existing valve assembly cannot connect multiple water tanks in series.

[0005] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a water-passing one-way valve assembly with a reasonable structure, convenient expansion of the number of water tanks, and quick disassembly and assembly.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The present invention discloses a quick-disassembly and detachable one-way valve assembly for water passage, comprising a first valve body and a second valve body. The first valve body is provided with a first pipe connector and a first interface, and the first interface contains a normally closed first valve core. The second valve body is provided with a second pipe connector and a second interface, and the second interface contains a normally closed second valve core. When the first interface and the second interface are paired and connected, the first valve core and the second valve core trigger each other, and the first pipe connector is connected to the second pipe connector through the first valve body and the second valve body. A detachable interlocking structure is provided between the first interface and the second interface.

[0008] Compared with the prior art, the first valve body of this utility model is provided with a first pipe connector, which can be connected to a water tank or water-using device through a hose. Similarly, the second valve body is provided with a second pipe connector, which can be connected to a water tank or water-using device through a hose. When the first valve body and the second valve body are connected, the first interface and the second interface are paired and locked together through an interlocking structure. The first valve core and the second valve core trigger each other, which can connect the water tank and the water-using device. There is no need to limit the positional relationship between the water tank and the water-using device, and they can be flexibly arranged.

[0009] Furthermore, in the multi-tank mode, each tank is connected to a first valve body and a second valve body. Two tanks are connected via the paired first and second valve bodies, and multiple tanks are connected in series to form an expandable chain-like water storage module. It is understandable that in this series-connected large-capacity water storage module, even if any tank is disassembled, the remaining tanks can still be interconnected and used.

[0010] Furthermore, the water-using device can be equipped with a tee / multi-way connector. This connector connects to multiple first or second valve bodies, and the water tanks are uniformly equipped with first or second valve bodies. Multiple water tanks can be connected in parallel to the tee / multi-way connector, forming a star-shaped water storage module. Of course, the tee / multi-way connector can be a solenoid valve, thereby controlling the connection between any water tank and the water-using device, allowing the device to use water stored in a designated tank.

[0011] According to the above scheme, the first interface is provided with a first sleeve, and the first valve core is provided inside the first sleeve; the second interface is provided with a second sleeve, and the second valve core is provided inside the second sleeve; the inner diameter of the first interface is adapted to the outer diameter of the second sleeve, and the inner diameter of the second sleeve is larger than the outer diameter of the first sleeve; when the first interface and the second interface are paired and connected, the first end of the second sleeve is inserted into the first interface, and the first sleeve is inserted into the second sleeve, so that the first valve core and the second valve core trigger each other, and the interlocking structure is provided between the first interface and the second sleeve.

[0012] It is understood that both the first and second valve bodies are hollow cylindrical structures, and the diameter of the second interface is similar to that of the first interface. The second end of the second sleeve is inserted into the second interface and fixedly installed inside the second valve body. When the first end of the second sleeve is inserted into the first interface, the second sleeve and the first valve body are aligned and positioned through a hole-shaft connection, ensuring that the first and second valve bodies are set along the same central axis.

[0013] Furthermore, the first sleeve is inserted into the second sleeve, and the two are also arranged along the same central axis, so that the first valve core and the second valve core are arranged opposite each other.

[0014] Furthermore, the second sleeve is inserted into the first interface, and there is a hole-shaft fit between the two. The interlocking structure can lock the second sleeve into the first interface, thereby making the first valve body and the second valve body paired and connected.

[0015] According to the above scheme, the first sleeve is provided with a corrugated sealing sleeve. When the first end of the second sleeve is inserted into the first interface, the corrugated sealing sleeve is inserted into the second sleeve. It can be understood that there is a diameter difference between the second sleeve and the first sleeve. The corrugated sealing sleeve fills the space between the first sleeve and the second sleeve, thereby maintaining a seal between the first valve body and the second valve body when they are connected.

[0016] According to the above scheme, the first valve core includes a first valve stem, a first spring, and a first sealing ring. The first valve stem is movably inserted into the first sleeve. A first rib is provided on the first end of the first valve stem. The first sealing ring is fitted on the first valve stem and abuts against the first rib. The first spring abuts between the first valve body and the first rib. The first spring can drive the first rib to move towards the first sleeve, thereby sealing the first sealing ring at the port of the first sleeve.

[0017] Understandably, the outer edge of the first valve stem is provided with several ribbed grooves, creating a water passage gap between the outer edge of the first valve stem and the inner edge of the first sleeve. The inner cavity of the first valve body communicates with the outside through this water passage gap. The first rib and the first sealing ring form a piston structure on the first end of the first valve stem. The first spring is compressed between the first valve body and the first rib. The first spring drives the first rib to always move towards the first sleeve, and the first sealing ring seals the first sleeve, cutting off the aforementioned water passage gap and keeping the first valve body in a normally closed state.

[0018] When the first valve core and the second valve core trigger each other, the first valve stem drives the first umbrella rib and the first sealing ring to move away from the first sleeve, so that the first pipe joint is connected to the second pipe joint through the first valve body and the second valve body.

[0019] According to the above scheme, a positioning sleeve is inserted into the first valve body. The first end of the positioning sleeve is integrally connected to the first sleeve, and a first inner step is formed between the positioning sleeve and the first sleeve. When the first umbrella rib moves towards the first sleeve, the first sealing ring can abut against the first inner step. The positioning sleeve and the first sleeve are an integral structure, and the diameter of the positioning sleeve is larger than the diameter of the first sleeve, thus forming the first inner step. The positioning sleeve is fixedly installed in the first valve body, thereby installing the first sleeve and the first valve core in the first interface. The first umbrella rib is used to install the first sealing ring and provide support for the first sealing ring, so that it can fit tightly against the first inner step. When the first sealing ring fits against the first inner step, the first sealing ring surrounds the first sleeve, cutting off the above-mentioned water passage gap, so that the first valve body is in a normally closed state.

[0020] According to the above scheme, the first valve body is provided with an assembly hole, the first pipe connector passes through the assembly hole, and the inner end of the first pipe connector is provided with a first end cap; the second end of the positioning sleeve is in contact with the first end cap, and a sealing element is provided between the positioning sleeve and the first end cap. The assembly hole and the first interface are respectively located at both ends of the first valve body. The first pipe connector and the first end cap are an integral structure. During assembly, the first pipe connector is inserted into the first valve body through the first interface. When the first end cap touches the first valve body, the first pipe connector extends out of the first valve body through the assembly hole. Then, the positioning sleeve, the first sleeve, and the first valve core are inserted into the first interface, so that the positioning sleeve abuts against the first end cap and a sealing element is provided. The sealing element includes a sealing ring, a sealing gasket, or a sealant.

[0021] According to the above scheme, the second valve core includes a second valve stem, a second spring, and a second sealing ring. A guide sleeve is provided inside the second sleeve, and a second inner step is formed between the guide sleeve and the second sleeve. The second valve stem is movably inserted into the guide sleeve, and a second rib is provided on the first end of the second valve stem. The second sealing ring is fitted onto the second valve stem and abuts against the second rib. The second spring abuts between the second valve body and the second rib, and the second spring can drive the second rib towards the guide sleeve, so that the second sealing ring abuts against the second inner step. As described above, the first valve core and the second valve core are symmetrically arranged. Several rib grooves are provided on the outer edge surface of the second valve stem, so that there is a water passage gap between the outer edge surface of the second valve stem and the inner edge surface of the guide sleeve. The inner cavity of the second valve body is connected to the outside through this water passage gap. The second umbrella rib and the second sealing ring form a piston structure on the first end of the second valve stem. The second spring is compressed between the second valve body and the second umbrella rib. The second spring drives the second umbrella rib to always tend toward the second sleeve. The second sealing ring fits against the second inner step and surrounds the guide sleeve, thereby cutting off the above-mentioned water passage gap and keeping the second valve body in a normally closed state.

[0022] When the first valve core and the second valve core trigger each other, the second valve stem drives the second umbrella rib and the second sealing ring to move away from the guide sleeve, so that the first pipe joint is connected to the second pipe joint through the first valve body and the second valve body.

[0023] According to the above scheme, the second valve body is provided with an assembly hole, the second pipe joint is inserted through the assembly hole, the inner end of the second pipe joint is provided with a second end cap, the second end of the second sleeve is in contact with the second end cap, and a sealing element is provided between the second sleeve and the second end cap.

[0024] The assembly hole and the second interface are respectively located at both ends of the second valve body. The second pipe connector and the second end cap are integral structures. During assembly, the second pipe connector is inserted into the second valve body through the second interface. When the second end cap touches the second valve body, the second pipe connector extends out of the second valve body through the assembly hole. Then, the second sleeve and the second valve core are inserted into the second interface, so that the second sleeve abuts against the second end cap and a sealing element is provided. The sealing element includes a sealing ring, a sealing gasket, or a sealant.

[0025] According to the above scheme, the interlocking structure includes a sliding groove and a locking slider. The first interface has at least one sliding groove, and the first end of the second sleeve has at least one locking slider. When the first end of the second sleeve is inserted into the first interface, the locking slider slides into the sliding groove and engages within it. It can be understood that the sliding groove includes a radial slide and a circumferential slide. When the second sleeve is inserted into the first interface, the locking slider enters the sliding groove from the radial slide. Then, by rotating the first valve body or the second valve body, the locking slider enters and engages within the circumferential slide, thus fixing the first valve body and the second valve body together.

[0026] Understandably, when the interlocking structure is locked, the first valve stem and the second valve stem contact each other, compressing the first spring and the second spring, thereby releasing the first valve core and the second valve core from their normally closed state, and allowing the first pipe joint to connect to the second pipe joint via the first valve body and the second valve body.

[0027] This utility model discloses a quick-assembly and disassembly one-way valve assembly for water flow. The first and second pipe connectors can be connected to a water tank or water-using device via flexible hoses. The first and second valve bodies are connected by an interlocking structure, which can be quickly paired to connect the water tank and the water-using device. Alternatively, the water tanks can be connected to each other through the first and second valve bodies. Connecting multiple water tanks in series can quickly expand the water capacity of the water-using device, making it flexible and convenient to use. Attached Figure Description

[0030] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0031] like Figure 1-3 As shown, the present invention provides a quick-disassembly and detachable one-way valve assembly, comprising a first valve body 1 and a second valve body 2. The first valve body 1 is provided with a first pipe connector 11 and a first interface 100, and the first interface 100 contains a normally closed first valve core 101. The second valve body 2 is provided with a second pipe connector 21 and a second interface 200, and the second interface 200 contains a normally closed second valve core 201. When the first interface 100 and the second interface 200 are paired and connected, the first valve core 101 and the second valve core 201 trigger each other, and the first pipe connector 11 connects to the second pipe connector 21 via the first valve body 1 and the second valve body 2. A detachable interlocking structure is provided between the first interface 100 and the second interface 200.

[0032] Compared with the prior art, the first valve body 1 of this utility model is provided with a first pipe connector 11, which can be connected to a water tank or water-using device through a hose. Similarly, the second valve body 2 is provided with a second pipe connector 21, which can be connected to a water tank or water-using device through a hose. When the first valve body 1 and the second valve body 2 are connected, the first interface 100 and the second interface 200 are paired and locked together through an interlocking structure. The first valve core 101 and the second valve core 201 trigger each other, which can connect the water tank and the water-using device. There is no need to limit the positional relationship between the water tank and the water-using device, and they can be flexibly arranged.

[0033] Furthermore, in the multi-tank mode, each tank is connected to a first valve body 1 and a second valve body 2. Two tanks are connected via the paired first valve body 1 and second valve body 2, and multiple tanks are connected in series to form an expandable chain-type water storage module. It is understandable that in this series-connected large-capacity water storage module, even if any tank is disassembled, the remaining tanks can still be interconnected and used.

[0034] Furthermore, the water-using device can be equipped with a three-way / multi-way connector, which connects multiple first valve bodies 1 or second valve bodies 2. The water tanks are uniformly equipped with first valve bodies 1 or second valve bodies 2, and multiple water tanks can be connected in parallel to the three-way / multi-way connector to form a star-shaped water storage module. Of course, the three-way / multi-way connector can be a solenoid valve, thereby controlling the connection state between any water tank and the water-using device, allowing the water-using device to use the water stored in a designated water tank.

[0035] The first interface 100 is provided with a first sleeve 12, and a first valve core 101 is disposed in the first sleeve 12. The second interface 200 is provided with a second sleeve 22, and a second valve core 201 is disposed in the second sleeve 22. The inner diameter of the first interface 100 is adapted to the outer diameter of the second sleeve 22, and the inner diameter of the second sleeve 22 is larger than the outer diameter of the first sleeve 12. When the first interface 100 and the second interface 200 are paired and connected, the first end of the second sleeve 22 is inserted into the first interface 100, and the first sleeve 12 is inserted into the second sleeve 22, so that the first valve core 101 and the second valve core 201 trigger each other. An interlocking structure is provided between the first interface 100 and the second sleeve 22.

[0036] It is understood that both the first valve body 1 and the second valve body 2 are hollow cylindrical structures, and the diameter of the second interface 200 is similar to that of the first interface 100. The second end of the second sleeve 22 is inserted into the second interface 200 and fixedly disposed inside the second valve body 2. When the first end of the second sleeve 22 is inserted into the first interface 100, the second sleeve 22 and the first valve body 1 are aligned and positioned through a hole-shaft connection, so that the first valve body 1 and the second valve body 2 are arranged along the same central axis.

[0037] Furthermore, the first sleeve 12 is inserted into the second sleeve 22, and the two are also arranged along the same central axis, so that the first valve core 101 and the second valve core 201 are arranged opposite each other.

[0038] Furthermore, the second sleeve 22 is inserted into the first interface 100, and there is a hole-shaft fit between the two. The interlocking structure can lock the second sleeve 22 into the first interface 100, thereby making the first valve body 1 and the second valve body 2 paired and connected.

[0039] Specifically, the interlocking structure includes a sliding groove 102 and a locking slider 202. The first interface 100 has at least one sliding groove 102, and the first end of the second sleeve 22 has at least one locking slider 202. When the first end of the second sleeve 22 is inserted into the first interface 100, the locking slider 202 slides into and engages within the sliding groove 102. It can be understood that the sliding groove 102 includes a radial slide and a circumferential slide. When the second sleeve 22 is inserted into the first interface 100, the locking slider 202 enters the sliding groove 102 from the radial slide. Then, by rotating the first valve body 1 or the second valve body 2, the locking slider 202 enters and engages within the circumferential slide, thus fixing the first valve body 1 and the second valve body 2 together.

[0040] Understandably, when the interlocking structure is locked, the first valve stem 14 and the second valve stem 23 contact each other, compressing the first spring 15 and the second spring 24, thereby releasing the normally closed state of the first valve core 101 and the second valve core 201, and allowing the first pipe joint 11 to connect to the second pipe joint 21 via the first valve body 1 and the second valve body 2.

[0041] In some embodiments, the interlocking structure includes internal threads and external threads. Since the first valve body 1 and the second valve body 2 are connected, the second sleeve 22 and the first valve body 1 are in a hole-shaft fit, and the first valve core 101 and the second valve core 201 are in an end-to-end contact fit, the first interface 100 can be provided with internal threads, and the second sleeve 22 can be provided with external threads. The two are interlocked through threaded connection.

[0042] In other embodiments, the interlocking structure between the first interface 100 and the second sleeve 22 can adopt the quick-connect structure used on air pipes and water pipes, and the interlocking method between the two includes elastic snap-fit ​​or magnetic locking.

[0043] The first sleeve 12 is provided with a corrugated sealing sleeve 13. When the first end of the second sleeve 22 is inserted into the first interface 100, the corrugated sealing sleeve 13 is inserted into the second sleeve 22. It can be understood that there is a diameter difference between the second sleeve 22 and the first sleeve 12. The corrugated sealing sleeve 13 fills the space between the first sleeve 12 and the second sleeve 22, thereby maintaining a seal between the first valve body 1 and the second valve body 2 when they are connected.

[0044] The first valve core 101 includes a first valve stem 14, a first spring 15, and a first sealing ring 16. The first valve stem 14 is movably inserted into the first sleeve 12. A first umbrella rib 141 is provided on the first end of the first valve stem 14. The first sealing ring 16 is fitted on the first valve stem 14 and abuts against the first umbrella rib 141. The first spring 15 abuts between the first valve body 1 and the first umbrella rib 141. The first spring 15 can drive the first umbrella rib 141 toward the first sleeve 12, thereby sealing the first sealing ring 16 at the port of the first sleeve 12.

[0045] It is understood that the outer edge of the first valve stem 14 is provided with several rib grooves, so that there is a water passage gap between the outer edge of the first valve stem 14 and the inner edge of the first sleeve 12, and the inner cavity of the first valve body 1 is connected to the outside through the water passage gap. The first umbrella rib 141 and the first sealing ring 16 form a piston structure on the first end of the first valve stem 14. The first spring 15 is compressed between the first valve body 1 and the first umbrella rib 141. The first spring 15 drives the first umbrella rib 141 to always tend towards the first sleeve 12. The first sealing ring 16 seals the first sleeve 12, cuts off the above-mentioned water passage gap, and keeps the first valve body 1 in a normally closed state.

[0046] When the first valve core 101 and the second valve core 201 trigger each other, the first valve stem 14 drives the first umbrella rib 141 and the first sealing ring 16 away from the first sleeve 12, so that the first pipe joint 11 is connected to the second pipe joint 21 through the first valve body 1 and the second valve body 2.

[0047] A positioning sleeve 17 is inserted inside the first valve body 1. The first end of the positioning sleeve 17 is integrally connected to the first sleeve 12, and a first inner step 171 is formed between the positioning sleeve 17 and the first sleeve 12. When the first umbrella rib 141 moves towards the first sleeve 12, the first sealing ring 16 can abut against the first inner step 171. The positioning sleeve 17 and the first sleeve 12 are integrally structured, and the diameter of the positioning sleeve 17 is larger than the diameter of the first sleeve 12, thus forming the first inner step 171. The positioning sleeve 17 is fixedly installed inside the first valve body 1, thereby installing the first sleeve 12 and the first valve core 101 inside the first interface 100. The first umbrella rib 141 is used to install the first sealing ring 16 and provide support for the first sealing ring 16, so that it can fit tightly against the first inner step 171. When the first sealing ring 16 fits against the first inner step 171, the first sealing ring 16 surrounds the first sleeve 12, cutting off the water passage gap and keeping the first valve body 1 in a normally closed state.

[0048] The first valve body 1 has an assembly hole, through which a first pipe connector 11 passes. The inner end of the first pipe connector 11 has a first end cap 111. The second end of the positioning sleeve 17 abuts against the first end cap 111, and a sealing element is provided between the positioning sleeve 17 and the first end cap 111. The assembly hole and the first interface 100 are respectively located at both ends of the first valve body 1. The first pipe connector 11 and the first end cap 111 are an integral structure. During assembly, the first pipe connector 11 is inserted into the first valve body 1 through the first interface 100. When the first end cap 111 touches the first valve body 1, the first pipe connector 11 extends out of the first valve body 1 from the assembly hole. Then, the positioning sleeve 17, the first sleeve 12, and the first valve core 101 are inserted into the first interface 100, so that the positioning sleeve 17 abuts against the first end cap 111 and a sealing element is provided. The sealing element includes a sealing ring, a sealing gasket, or sealant.

[0049] The second valve core 201 includes a second valve stem 23, a second spring 24, and a second sealing ring 25. A guide sleeve 26 is provided inside the second sleeve 22, forming a second inner step 261 between the guide sleeve 26 and the second sleeve 22. The second valve stem 23 is movably inserted into the guide sleeve 26, and a second rib 231 is provided on the first end of the second valve stem 23. The second sealing ring 25 is fitted onto the second valve stem 23 and abuts against the second rib 231. The second spring 24 abuts between the second valve body 2 and the second rib 231, and the second spring 24 can drive the second rib 231 towards the guide sleeve 26, causing the second sealing ring 25 to abut against the second inner step 261. Similarly, the first valve core 101 and the second valve core 201 are symmetrically arranged. Several rib grooves are provided on the outer edge surface of the second valve stem 23, creating a water passage gap between the outer edge surface of the second valve stem 23 and the inner edge surface of the guide sleeve 26. The inner cavity of the second valve body 2 communicates with the outside through this water passage gap. The second umbrella rib 231 and the second sealing ring 25 form a piston structure on the first end of the second valve stem 23. The second spring 24 is compressed between the second valve body 2 and the second umbrella rib 231. The second spring 24 drives the second umbrella rib 231 to always tend toward the second sleeve 22. The second sealing ring 25 fits against the second inner step 261 and surrounds the guide sleeve 26, thereby cutting off the above-mentioned water passage gap and keeping the second valve body 2 in a normally closed state.

[0050] When the first valve core 101 and the second valve core 201 trigger each other, the second valve stem 23 drives the second umbrella rib 231 and the second sealing ring 25 away from the guide sleeve 26, so that the first pipe joint 11 is connected to the second pipe joint 21 through the first valve body 1 and the second valve body 2.

[0051] The second valve body 2 is provided with an assembly hole, the second pipe joint 21 passes through the assembly hole, the inner end of the second pipe joint 21 is provided with a second end cap 211, the second end of the second sleeve 22 is in contact with the second end cap 211, and a sealing element is provided between the second sleeve 22 and the second end cap 211.

[0052] The assembly hole and the second interface 200 are respectively located at both ends of the second valve body 2. The second pipe connector 21 and the second end cap 211 are integral structures. During assembly, the second pipe connector 21 is inserted into the second valve body 2 through the second interface 200. When the second end cap 211 touches the second valve body 2, the second pipe connector 21 extends out of the second valve body 2 through the assembly hole. Then, the second sleeve 22 and the second valve core 201 are inserted into the second interface 200, so that the second sleeve 22 abuts against the second end cap 211 and a sealing element is provided. The sealing element includes a sealing ring, a sealing gasket, or a sealant.

[0053] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
