As shown in fig. 1 to 6, the present embodiment provides an anti-overflow joint, which is used to prevent overflow of the end of a pipeline remaining in a waterway system during the process of removing and replacing the pipeline or waterway component in the waterway system, which may result in an increase in the failure rate of the waterway system.

The anti-overflow joint is used for connecting a waterway channel between a pipeline or a waterway element in the application of a waterway system.

The waterway system in this embodiment includes, but is not limited to, a water supply system, a circulating water system, and a water supply system. Wherein, the water supply system refers to a water storage, a water pump 50, a pipeline and other engineering complex needed by different water departments according to certain quality requirements. The circulating water system is a water path system which sends cooling water (seawater) to the high-low pressure condenser to cool the low pressure cylinder of the steam turbine to discharge steam so as to maintain the vacuum of the high-low pressure condenser and enable steam-water circulation to be continued. The water supply system is a waterway network which is organically conveyed to a water using place according to the production, life and fire fighting requirements of buildings and users through pipelines and auxiliary equipment.

The above-mentioned system and some other waterway systems all need to be composed of pipelines, devices, elements and the like, the anti-overflow joints of the embodiment can be arranged between the pipelines and between the devices, elements and the pipelines, when any part of the pipelines or the system connected with the pipelines needs to be replaced, the water pressure in the pipelines can be reduced by stopping the operation of the system, and then the pipelines and the parts are dismantled.

Specifically, in the disassembling process, the anti-overflow joint can be connected between two pipelines or between a pipeline and a component, the pipeline or the component needing to be disassembled is only required to be disassembled from one end of the anti-overflow joint in the disassembling process, and the other end of the anti-overflow joint still remains to be connected with the pipeline which is not disassembled in the system, so that water still in the pipeline in the system can be prevented from overflowing outwards through the anti-overflow joint, the phenomenon that overflowing water causes short circuit damage to the device component in the system or the sanitation environment around the system is damaged is avoided.

In order to achieve the technical effects, the joint main body of the anti-overflow joint is of a hollow structure. In order to match the anti-overflow connector with the waterway connector of the pipeline and waterway component in the waterway system, the connector body 10 is also tubular. A water passing cavity 11 for guiding water flow between pipelines and between the pipelines and an original is formed in the middle through inner cavity of the joint body 10. A first water through hole 12 and a second water through hole 13 which are communicated with the water through cavity 11 and the external space are arranged at any two positions of the joint body 10 at intervals. The first water through hole 12 and the second water through hole 13 are mainly used for being connected with a pipeline or a waterway element in the application process of the anti-overflow joint, and are used for water inlet and water outlet. When one is configured for water intake use, the other is configured for water output use. The first water through hole 12 and the second water through hole 13 are generally disposed at two opposite ends of the water through cavity 11, and the specific positions of the two water through holes can be set according to the requirement of the pipeline installation position of the waterway system.

For example, in the water purification system according to the embodiment shown in fig. 7, the filter body 30 needs to be embedded on the fixing base 60 from the upper side of the fixing base 60 due to the structural relationship between the filter body 30 and the fixing base 60 for fixing the filter body 30. Therefore, one end of the spill prevention joint is required to face the upper portion of the fixing base 60, and the filter body 30 is required to discharge or supply water from one side of the fixing base 60, and the other end of the spill prevention joint is arranged to protrude from the side of the fixing base 60.

In the joint body 10 of the present embodiment, in the radial projection direction of the water passing cavity 11, the center extension lines of the first water passing hole 12 and the second water passing hole 13 intersect at 90 °.

Of course, this should not be taken as a limitation on the present embodiment. As described above, the first water through hole 12 and the second water through hole 13 can be adjusted according to the difference of the waterway structure, and are not limited to be provided with only two water through holes, and the number of the water through holes can also be three, four or more, so that the anti-overflow joint is configured into a multi-way joint such as a tee joint, a four-way joint and the like.

It can be understood that the connector body 10 is generally identical to the conventional waterway connector structure, and can be manufactured by using different materials according to different requirements of the waterway system. If the anti-overflow joint needs to be applied to a waterway system with higher water pressure and stronger joint rigidity, such as a large-scale water purification system and the waterway system mentioned above, the anti-overflow joint can be made of metal, and the metal anti-overflow joint can be produced by processes of cold rolling, extrusion and the like of a pipe rolling machine set. If the waterway system is applied to waterway systems with low water pressure and relatively more frequent replacement of parts, the anti-overflow joint can be produced by adopting materials such as plastics, silica gel and the like and can be produced by processes such as injection molding, extrusion and the like when the civil water purification system (a clothes care machine, a drinking water purification system or a domestic water purification system) is adopted in the embodiment.

Because the anti-overflow joint in this embodiment mainly is applied to in the middle of the water purification system of clothe nursing machine, and the water pressure in its pipeline is lower, and filter body 30 changes comparatively frequently, consequently, the anti-overflow joint in this embodiment adopts softer materials such as silica gel to make, and the part plug of being convenient for is replaced, and its rigidity can satisfy waterway system's requirement again simultaneously, suitably reduction in production cost.

An anti-overflow diaphragm 20 is arranged in the water passing cavity 11.

Specifically, the anti-overflow membrane 20 is located between the first water through hole 12 and the second water through hole 13. In order to achieve the anti-overflow effect, the anti-overflow membrane 20 covers the overflow chamber 11 in the axial direction of the overflow chamber 11. The spill-proof membrane 20 has an elastic portion. The elastic part is provided with at least one cutting slit 21, so that the elastic part is divided by the cutting slit 21 to form at least two elastic blocking sheets 22.

It is understood that the entirety of the overflow preventing membrane 20 may be made of a material having elastic restorability such that the overflow preventing membrane 20 is integrally formed with the above elastic portion. Of course, the periphery of the anti-overflow membrane 20 may be made of other hard materials to facilitate connection with the water passing cavity 11 of the joint body 10, and the elastic portion is formed by disposing a material having elastic restoring capability in the middle of the anti-overflow membrane 20.

In order to allow the anti-overflow diaphragm 20 to be installed in the water passing chamber 11, for example, the joint body 10 is made of metal, the outer periphery of the anti-overflow diaphragm 20 may be made of hard plastic or metal to form a ring-shaped member with a peripheral structure matched with the inner cavity structure of the water passing chamber 11. A hole capable of passing water is reserved in the middle path, and the hole is covered with an elastically resettable material in a gluing mode, a fastening mode and the like. The periphery of the anti-overflow membrane 20 can be fixed in the water passing cavity 11 by arranging clamping blocks in the water passing cavity 11 for clamping, bonding and the like, so that the membrane is convenient to replace.

It should be noted that a good water-tightness is required between the outer periphery of the overflow preventing membrane 20 and the inner periphery of the water passing chamber 11 to prevent water from passing between them. In the embodiment where the connector body 10 is made of plastic, silica gel or other materials, the integral material of the anti-overflow membrane 20 may be the same as that of the connector body 10, and the anti-overflow membrane 20 is injection molded into the connector body 10 when the connector body 10 is produced through injection molding or other processes, so that not only can the water tightness between the anti-overflow membrane 20 and the water passing cavity 11 be ensured, but also the production efficiency of the product is improved.

As mentioned above, the end of the elastic blocking piece 22 close to the slit 21 is a free end, and the free end of the elastic blocking piece 22 can be opened under the action of external force and keep the elastic blocking pieces 22 against each other without the action of external force to keep the slit 21 closed.

It will be appreciated, therefore, that the material used for the resilient portion, in addition to having resilient return capability, also needs to have a certain water tightness with the resilient flaps 22 abutting against each other for closure. When the anti-overflow joint is in a normal state, the elastic blocking pieces 22 are mutually abutted to keep the cutting seams 21 sealed and closed so as to block the water channel between the first water passing hole 12 and the second water passing hole 13. The water in the water passing cavity 11 at one end of the first water passing hole 12 cannot flow to the water passing cavity 11 at one end of the second water passing hole 13 through the anti-overflow membrane 20, and the water in the water passing cavity 11 at one end of the second water passing hole 13 cannot flow to the water passing cavity 11 at one end of the first water passing hole 12 through the anti-overflow membrane 20. The elastic blocking piece 22 can be expanded in a direction away from each other under the action of external force to communicate the first water through hole 12 and the second water through hole 13, so that the waterway channel is communicated.

As shown in fig. 1-3 and 9-12, the spill-proof joint has two states of the elastic portion in a specific application scenario. The first water passing hole 12 is used for being connected with a pipeline or an element which needs to be periodically detached and replaced, the second water passing hole 13 is used for being connected with the pipeline or the element which needs to be replaced, for example, the pipeline or the element which basically does not need to be replaced is connected, the second water passing hole 13 is generally kept connected with the pipeline, the anti-overflow membrane 20 is arranged close to the first water passing hole 12, so that a connector on the pipeline or the element which is detachably connected with the first water passing hole 12 can apply certain external force to the elastic part when being connected into the first water passing hole 12, the free end of the elastic baffle plate 22 can be opened towards the direction far away from the first water passing hole 12 under the action of the external force, and the cutting joint 21 is enlarged, so that the pipeline or the waterway element which is connected into the first water passing cavity 11 and the pipeline which is connected into the second water passing hole 13 are communicated. When the external force acting on the elastic blocking pieces 22 is removed, that is, when the pipeline or the element connected to the first water passing cavity 11 is detached from the joint body 10, the elastic blocking pieces 22 are elastically restored in the direction of approaching each other. Support each other under the spring action and paste closed joint-cutting 21, the cavity of crossing water 11 is covered again to the separation inserts the second and crosses the pipeline in water hole 13 and external intercommunication, avoids remaining the water in the pipeline of inserting the second and crossing water hole 13 and the water in the cavity of crossing water 11 and overflows from first water hole 12 and connect body 10.

Through adopting foretell anti-overflow joint structure to cooperate its theory of operation, when anti-overflow joint is applied to water purification system and the clothing care machine in this embodiment, anti-overflow joint is used as connecting filter body 30 and water pump 50, can prevent the condition that the water of filter body 30 in dismantling, change in-process pipeline from spilling over, keep water purification system surrounding environment dry relatively, the higher fault rate that leads to of reduction humidity rises, and avoid water purification system's bacterial growing, ensure that water purification system keeps good quality of water, let the clothing care effect of clothing care machine more stable.

As an alternative embodiment, the first water flowing hole 12 is used as a connecting end of a component that needs to be replaced periodically, and the first water flowing hole 12 is provided with a connector 14, which is configured to be conveniently matched with a connector of a pipeline or a waterway component in an inserting manner, so as to improve the convenience and efficiency of the disassembly and assembly of the pipeline and the component.

The structure of the connector 14 is a tubular structure matched with the pipeline and a corresponding joint structure, and is also a through structure with two communicated ends, one end of the connector 14 is communicated with the water passing cavity 11, and the other end of the connector 14 is used for connecting the pipeline in the waterway system or connecting the pipeline connected with the second water passing hole 13 to a waterway element.

It is understood that, in this structure, the end of the connecting head 14 away from the joint body 10 forms the first water passing hole 12, i.e., the anti-overflow membrane 20 is disposed between the connecting head 14 and the second water passing hole 13.

Specifically, the inner cavity wall of the connector 14 is formed with a sealing rib 141 in a surrounding manner, and the sealing rib 141 can ensure that when the connector 14 is connected with a pipeline or a waterway element, the water passing cavity 11 and the corresponding pipeline or waterway element have good water tightness.

The sealing ribs 141 are required to be tightly connected with the corresponding connecting parts when the connecting head 14 is connected with the pipeline or the element, so as to ensure good water tightness between the parts. Therefore, the sealing rib 141 needs to be made of a material with elasticity, and when the sealing rib 141 itself and the inner cavity of the connector 14 need to maintain sealing, and the sealing rib 141 abuts against an external pipeline or an element connector, it is also necessary to maintain good water tightness between the sealing rib 141 and the connector, so as to prevent water from passing between the sealing rib 141 and the connector.

In the case where the joint body 10 is made of a metal material, the joint head 14 is formed integrally with the joint body 10 by using the same material, and the material of the seal rib 141 is different from that of the joint head 14, so that the seal rib 141 needs to be assembled from the outside of the joint head 14 after the spill-proof joint is manufactured and formed. The sealing rib 141 can be a conventional sealing ring band, and an annular groove is formed in the inner cavity wall of the connector 14, so that the sealing ring is clamped in the corresponding groove to form a watertight structure. In the case where the joint body 10 is made of plastic, silicone, or the like, the material of the joint head 14 is the same as that of the joint body 10, and is integrally formed. On this basis, the sealing rib 141 may be produced by using the same material as the connector 14, and in order to improve the production efficiency, the sealing rib 141 may be integrally formed in the inner cavity of the connector 14 when the anti-overflow connector is injection molded or is formed by using other processes. Therefore, the water tightness between the sealing rib 141 and the connector 14 is ensured, and the production difficulty of the anti-overflow connector is reduced.

In order to further improve the water tightness between the connection head 14 and the pipe or element connection to which it is correspondingly connected, the sealing rib 141 is provided at least twice. In this embodiment, the sealing ribs 141 and the connector 14 are integrally formed, and the number of the sealing ribs 141 is two, for example, the two sealing ribs 141 are sequentially arranged at intervals along the axial direction of the connector 14. When the pipe or the element joint is inserted into the inner cavity of the connector 14, the outer diameter of the pipe or the element joint needs to be larger than the size of the inner ring of the sealing rib 141 and smaller than the size of the inner cavity of the connector 14. Thus, when the connector 14 is inserted smoothly, the inner ring of the rib 141 is pressed against the rib 141 to deform the rib 141, thereby maintaining water tightness.

Specifically, since the first water passing hole 12 is intended to be used as one end connected to a pipe or component to be replaced periodically in this embodiment, when the pipe or component joint is connected to the connector 14, the elastic blocking piece 22 moves away from the first water passing hole 12. In order to avoid interference between the elastic blocking piece 22 and the anti-overflow membrane 20 and the sealing rib 141 in the process, so that the elastic blocking piece 22 blocks part of the sealing rib 141, thereby affecting the water seal between the pipe or the element connector after the pipe or the element connector is completely plugged into the connector 14, the anti-overflow membrane 20 is preferably arranged between the sealing rib 141 and the second water through hole 13 in the embodiment.

As shown in fig. 9 to 12, in this arrangement, when the pipe or the element joint is inserted into the connection head 14, the outer wall of the pipe or the element joint first abuts against the sealing rib 141 in the connection head 14. When the pipe or component joint is further inserted, the end of the pipe or component joint will abut against the elastic portion, so as to apply a force to the elastic flap 22 as the pipe or component joint is further inserted, and finally the elastic flap 22 is moved to expand the slit 21.

In the last embodiment, the elastic pieces 22 may be formed by punching the slits 21 in the elastic portion, or at least two elastic pieces 22 may be separately provided and closed to form the corresponding slits 21.

As can be seen from the foregoing description, the deployment direction of the elastic portion formed by the elastic flap 22 may be bidirectional or unidirectional. In practical application, under conventional conditions, the multi-disc elastic separation blade 22 can be towards the expansion direction protrusion, lets it only can pass the water cavity 11 expansion of water hole 13 direction one side towards the second to improve the backstop ability to water hole 13 one side of second under the closed state, avoid the water cavity 11 water pressure of passing water hole 13 one side of second to push up elastic separation blade 22 when slightly bigger, its specific structure can refer to the valve structure in the human blood vessel.

As shown in fig. 4-6, it can be understood that the slits 21 on the elastic portion can be, but not limited to, cross slits 21, in-line slits 21, Y slits 21, V slits 21, 20866, or i slits 21, or curved slits 21 (e.g., semicircular slits).

The water purification system mentioned in this embodiment employs two above-mentioned anti-overflow joints, and specifically further includes a filter body 30, a water storage tank 40, and a water pump 50.

As shown in fig. 7-8, a hollow water filtering chamber 31 is formed inside the filter body 30, a water inlet pipe 33 and a water outlet pipe 34 extend from the filter body 30, and the water inlet pipe 33 and the water outlet pipe 34 are communicated with the water filtering chamber 31.

In particular, in the present water purification system, the water filtering chamber 31 is used for filling the filter element 32. The type of filter element 32 may depend on the particular application of the filter body 30 and the requirements of the water service device. The filter element 32 can be an activated carbon filter element 32, a PP filter element 32, a ceramic filter element 32, a resin filter element 32, a titanium rod filter element 32, an RO reverse osmosis membrane, a nanofiltration membrane, a hollow fiber ultrafiltration membrane, or the like.

In this embodiment, the water purification system is applied to the clothes care machine, and in order to improve the clothes care machine in the clothes shaping effect, the filter element 32 is made of resin, specifically, a plurality of granular ion exchange resins, and softens the water supply system of the clothes care machine, removes calcium and magnesium ions, reduces the scale of the boiler 70, or reduces the calcium and magnesium ions remaining on the clothes, and prevents the clothes from yellowing and hardening.

In order to connect the filter body 30 to the anti-overflow connector, the diameter of the water inlet pipe 33 and the diameter of the water outlet pipe 34 are both smaller than the diameter of the first water passing hole 12 or smaller than the diameter of the second water passing hole 13, so that the water inlet pipe 33 and the water outlet pipe 34 can be connected to the connector body 10 by plugging the first water passing hole 12 or the second water passing hole 13.
