Detailed Implementation

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.

[0041] The terms "first," "second," and "third" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] In the dishwasher industry, sewage backflow in the drain pipe has always been a problem that urgently needs to be solved. In the current technology, electromagnetic plugs or one-way valves are used to block the drain pipe. Although one-way valves are cheaper, they cannot control the sewage discharge time and may leak odors. Moreover, with long-term use, the plug may become unstable and leak sewage. On the other hand, most existing electromagnetic plugs are very complex in structure because they require additional sensors to determine whether the electromagnetic plug is completely sealed, resulting in a large size and high cost.

[0044] The purpose of this application is to overcome the defects and deficiencies in the prior art and provide a water-blocking valve that aims to solve the problems of unstable sewage backflow caused by conventional plugging methods, large size of electromagnetic plugs, high cost, and complex structure.

[0045] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the water-blocking valve according to an embodiment of this application. Figure 2 yes Figure 1 An exploded view of the water-blocking valve in this embodiment shows that the valve includes a seal 10, a drive assembly 20, a housing 30, and a connector 40. The seal 10 forms a sealed fit with the water inlet pipe 70. The housing 30 forms an accommodating space, and the seal 10 is disposed outside and connected to the housing 30. One end of the connector 40 is disposed within the accommodating space and forms a transmission fit with the drive assembly 20, while the other end is connected to the seal 10. The drive assembly 20 includes a transmission component 200 and a drive component 201. In some embodiments, the transmission component 200 has multiple transmission features, and the transmission component 200 is a reduction gear set. The moving part 200 includes a first transmission part 200 and a second transmission part 200. The first transmission part 200 is connected to the connecting rod, and the second transmission part 200 is connected to the driving part 201. The second transmission part 200 is used to transmit the driving force of the driving part 201 to the first transmission part 200, thereby transmitting it to the connecting part 40. The speed reduction function can be achieved by setting the transmission characteristics of the first transmission part 200 and the second transmission part 200. The driving part 201 is a drive motor. The drive motor transmits power to the connecting part 40 through a worm gear and a reduction gear set, thereby causing the connecting part 40 to drive the sealing part 10 to move.

[0046] like Figure 1 and Figure 2 As shown, the water-blocking valve is also provided with a first elastic element 50, which is disposed inside the sealing element 10. In some embodiments, the first elastic element 50 is a spring. The first elastic element 50 is always in a compressed state. In order for the sealing element 10 to block and open the water inlet pipe 70, the sealing element 10 has a certain elasticity and a certain compressive strength. Therefore, the sealing element 10 is a rubber plug that cooperates with the water inlet pipe 70. The sealing element 10 is divided into a plug section and an elastic section. The elastic section is a hollow rubber part that is elastic, spring-shaped, and can be compressed and extended. The elastic section of the sealing element 10 is connected to the housing 30, so that the sealing element 10 can extend and retract along the housing 30. The first elastic element 50 is disposed inside the sealing element 10, so that the sealing element 10 tends to return to its original position when compressed. At the same time, when the sealing element 10 is in a sealed state, the first elastic element 50 can compress the sealing element 10 to make it in close contact with the water inlet pipe 70.

[0047] like Figure 3 and Figure 4 As shown, Figure 3 yes Figure 1 A schematic diagram of the elevation structure of the water-blocking valve in a closed state in the embodiment. Figure 4 yes Figure 3The schematic diagram of the cross-sectional structure of the water-blocking valve at point AA in the embodiment shows that, in order to enable the connecting member 40 to slide against the housing 30 while also driving the seal 10 to move at the center of the seal 10, the connecting member 40 is a connecting rod and includes a first section 400 and a second section 401. The first section 400 is provided with a transmission engagement member 4002 and forms a transmission engagement with the transmission member 200. The second section 401 drives the seal 10 to seal or open the water inlet pipe 70. A limiting member 4011 is also provided between the first segment 400 and the second segment 401. The first segment 400 and the second segment 401 are arranged parallel to each other, and the limiting member 4011 is perpendicular to the first segment 400 and the second segment 401. When the first segment 400 slides to the housing 30, the limiting member 4011 abuts against the housing 30, thereby limiting the sliding position of the first segment 400. A limiting groove 60 is provided on the connecting surface of the housing 30 and the sealing member 10, and the limiting groove 60 protrudes towards the sealing member 10, thereby allowing the second segment 401 of the connector 40 to... The limiting groove 60 is engaged, and the second segment 401 passes through the limiting groove 60 and connects with the seal 10. The end of the second segment 401 and the seal 10 are provided with a mating connector 4010. The second segment 401 drives the seal 10 to move through the mating connector 4010. The mating connector 4010 can be, but is not limited to, a protrusion that engages with the seal 10 and the connector 40. Setting the mating connector 4010 separately, rather than as an integral part of the connector 40 or the seal 10, facilitates the installation of the overall water-blocking valve 1.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, Figure 5 yes Figure 4 The enlarged cross-sectional view of the water-blocking valve at point B in the embodiment shows that a sliding part 400 is provided on the side of the first segment 400 facing the housing 30, and a sliding fit feature 300 is provided on the side of the housing 30 facing the connector 40. The sliding part 4000 and the sliding fit feature 300 engage with each other. In some embodiments, the housing 30 can restrict the sliding position of the first segment 400, thereby enabling the connector 40 to move more stably and reducing the probability of sliding misalignment during sliding.

[0049] like Figure 4 and Figure 5 As shown, a transmission fitting 4002 is provided on the connector 40, and the transmission fitting 4002 and the transmission member 200 form a transmission fit; the transmission fitting 4002 includes a first transmission fitting 4003 and a second transmission fitting 4004, and the first transmission fitting 4003 is disposed on the side of the second transmission fitting 4004 facing the seal member 10.

[0050] like Figure 4 and Figure 5 As shown, the transmission mating member 4002 is disposed on the side of the sliding part 4000 facing away from the housing 30. The sliding part 4000 is provided with a first receiving groove 4001 on the side facing away from the housing 30. The second transmission mating member 4004 is disposed in the first receiving groove 4001 and can slide in the first receiving groove 4001. In some embodiments, the first receiving groove 4001 is a sliding space that matches the second transmission mating member 4004, so that the second transmission mating member 4004 can slide therein. The second transmission member 200 includes a second elastic member 4004b and a second transmission mating feature 4004a. One end of the second elastic member 4004b abuts against the connecting member 40, and the other end of the second elastic member 4004b abuts against the second transmission mating feature 4004a. The second elastic member 4004b can be, but is not limited to, a spring that is always in a compressed state. A second receiving groove 4004c is provided in the second transmission fitting 4004, and a second elastic member 4004b is disposed in the second receiving groove 4004c. In some embodiments, the second receiving groove 4004c and the second elastic member 4004b are matched in shape, and the second receiving groove 4004c is formed by the second transmission fitting 4004. The opening of the second receiving groove 4004c faces the first transmission fitting 4003. The second elastic member 4004b abuts against the second transmission fitting 4004 in the second receiving groove 4004c, so that the second transmission fitting 4004 abuts against the housing 30, and the second elastic member 4004b is always compressed. When the second elastic member 4004b is subjected to external force, it can move in the first receiving groove 4001. When the external force disappears, it can be restored to its original position by the force of the second elastic member 4004b, thereby achieving the idling condition.

[0051] like Figure 6 As shown, Figure 6 yes Figure 4 An enlarged schematic diagram of another embodiment of the water-blocking valve structure shows that in this embodiment, the second elastic element 4004b is an elastic rubber component that is always in a compressed state. The second elastic element 4004b is disposed in the second receiving groove 4004c, and its two ends are fixedly connected to the second transmission engagement feature 4004a and the connecting member 40, respectively. By keeping the second elastic element 4004b in a compressed state, it can move within the first receiving groove 4001 when subjected to external force. When the external force disappears, it can be restored to its original position by the force of the second elastic element 4004b, thereby achieving the idling condition. This embodiment does not need to consider the positional relationship of the spring in the previous embodiment, resulting in stronger stability, but the assembly is more complex and the cost is higher.

[0052] In other embodiments, there may be multiple ways to combine the second elastic element 4004b and the second transmission engagement feature 4004a. In these embodiments, the engagement methods of the second elastic element 4004b and the second transmission engagement feature 4004a are similar, so they will not be described in detail. Their protection scope is included in this application.

[0053] like Figure 4 As shown, when the water-blocking valve 1 is in a sealed state, a transmission feature and a second transmission mating feature 4004a engage, and the second transmission mating feature 4004a moves along the first receiving groove 4001, causing the transmission feature to slide along the second transmission mating feature 4004a, thus causing free rotation. When the transmission feature is free rotating along the second transmission mating feature 4004a, the second elastic member 4004b drives the second transmission mating feature 4004a to move in the opposite direction to the opening of the second receiving groove 4004c, causing the second transmission mating feature 4004a to move to abut against another transmission feature. The above process is repeated, causing multiple transmission features and the second transmission mating feature 4004a to engage in free rotation, thereby causing the second transmission mating member 4004 to reciprocate. In some embodiments, the transmission feature is a gear tooth, and the second transmission engagement member 4004 is an independent locking block with a single locking tooth. The transmission member 200 drives the second transmission engagement member 4004 to move. Because the second transmission engagement member 4004 has only one locking tooth, the second transmission engagement member 4004 is disposed in the first receiving groove 4001, and the compressed second elastic member 4004b in the second transmission engagement feature 4004a abuts against the housing 30. Therefore, one transmission feature overcomes the force of the compressed second elastic member 4004b to drive the second transmission engagement member 4004 to move along the first receiving groove 4001 until the transmission feature and the second transmission engagement member 4004 idle. At this time, the second transmission engagement member 4004 is subjected to the force of the compressed second elastic member 4004b, thereby moving along the first receiving groove 4001 until it abuts against another transmission feature. The second transmission engagement member 4004 repeats the above process, thereby forming an idle engagement, until the driving member 201 stops.

[0054] This application achieves automatic unblocking of the water inlet pipe 70 by cooperating with the drive component 201, the connector 40, and the seal 10, and by moving the seal 10. At the same time, the transmission component 4002 and the transmission component 200 form a free-spinning engagement, so that when the seal 10 reaches the blocked state, there is no need to set up a sensor to precisely control the drive component 20 to stop, which reduces costs and avoids damage to the seal 10 due to excessive rotation of the drive component 20. In addition, the cooperation of the drive component 201, the connector 40, and the seal 10 ensures that the movement of the seal 10 is not affected by the pipe pressure fluctuation, and stably and efficiently prevents sewage backflow due to pipe pressure fluctuation.

[0055] On the other hand, this application also provides a valve-pump integrated device, such as... Figure 7 As shown, Figure 7 This is a schematic diagram of the integrated valve and pump device according to an embodiment of this application, including: the aforementioned water-blocking valve, drainage mechanism 7, and drainage pump 8. The drainage mechanism 7 includes an inlet pipe 70, an outlet pipe 71, and a connecting pipe 72. The drainage pump 8 includes a rotating assembly 80, a driver 81, and a support member 82. The water-blocking valve abuts against the inlet pipe 70, the connecting pipe 72 is located between the inlet pipe 70 and the outlet pipe 71, and the drainage pump 8 is disposed between the outlet pipe 71 and the connecting pipe 72. In some embodiments, sewage flows into the integrated valve and pump device from the inlet pipe 70. At this time, the water-blocking valve opens, and the sewage enters the drainage pump 8 through the connecting pipe 72. The drainage pump 8 operates to accelerate the discharge rate of the sewage.

[0056] like Figure 8 , Figure 9 and Figure 10 As shown, Figure 8 This is an exploded view of the structure of the water-blocking valve according to an embodiment of this application. Figure 9 yes Figure 8 A schematic diagram of the elevation structure of the drainage pump in the embodiment. Figure 10 yes Figure 9 In the embodiment, the drainage pump is shown in a cross-sectional view at DD. The rotating assembly 80 includes a rotating component 800 and a rotating connector 801. A support component 82 is located between the rotating component 800 and the driver 81. The connecting pipe 72 has an opening facing the support component 82, and the support component 82 fits tightly with the opening. The rotating component 800 is located in the connecting pipe 72. The support component 82 is conical facing the opening and has a clearance groove. The rotating connector 801 passes through the support groove and enters the driver. The rotating connector 801 connects the rotating component 800 and the driver 81. The driver 81 drives the rotating connector 801 to rotate, thereby driving the rotating component 800 to rotate.

[0057] like Figure 8 and Figure 10As shown, in some embodiments, the rotating component 800 is an impeller, and includes a bearing assembly 8000, a central column 8001, and multiple fan blades. The bearing assembly 8000 facilitates smoother rotation of the rotating component 800. One end of each fan blade is fixedly connected to the central column 8001, while the other end is a free end. The free ends of the multiple fan blades are located on the same circle, with the central axis of the central column 8001 at the center of this circle. By employing a conical support 82 and setting the overall proportion of the central column 8001, the water-receiving area is increased without changing the installation space of the support 82. The rotation of the rotating component 800 and the interaction between the drainage and the conical surface of the support 82 generate vortices, effectively increasing the drainage flow rate. The support 82 has a uniform wall thickness, resulting in both its inner and outer walls being conical surfaces. The diameter of the central column 8001 reduces its proportion in the overall rotating component 800, thereby increasing the length of the fan blades and improving the drainage capacity of the rotating component 800. In some embodiments, the number of fan blades may be, but is not limited to, 4-10 blades. In some embodiments, the number of fan blades may be 6, 7, or 8 blades.

[0058] In some embodiments, the inner wall of the support member 82 is a conical surface, and the angle between the conical surface and its central axis is 50-80°. Within this range of taper, the support member 82 not only has a good fit with the rotating member 800 to generate a vortex effect, but also has a good fit with the installation space of the driver 81 and the rotating member 800.

[0059] like Figure 8 and Figure 10 As shown, the rotating connector 801 includes a connecting portion 8010, a snap-fit ​​portion 8011, and a rotating mating member 8012. In some embodiments, the support member 82 extends into a receiving member 820 in the opening direction. The rotating connector 801 is disposed within the receiving member 820. The connecting portion 8010 connects to the rotating member 800. The snap-fit ​​portion 8011 is disposed on the connecting portion 8010. The snap-fit ​​portion 8011 and the connecting portion 8010 are disposed within the rotating mating member 8012. The rotating mating member 8012 may be, but is not limited to, a hollow magnetic core. The snap-fit ​​portion 8011 is used to snap the connecting portion 8010 into the rotating mating member 8012, thereby causing the connecting portion 8010 to drive the rotating member 800 to rotate.

[0060] like Figure 8 and Figure 10 As shown, the driver 81 includes a first driving part 810 and a second driving part 811. In some embodiments, the first driving part 810 is a plastic-encapsulated coil and the second driving part 811 is an iron core. The first driving part 810 is provided with a snap-fit ​​groove, and one end of the second driving part 811 is snapped into the snap-fit ​​groove, while the other end forms a ring shape and is snapped into the receiving member 820.

[0061] like Figure 8 and Figure 10As shown, a cooling groove 83 is provided between the support member 82 and the driver 81. The cooling groove 83 surrounds the second drive unit 811 and is used for air heat exchange to remove the heat generated by the second drive unit 811 during operation.

[0062] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent changes in mechanism or process made based on the content of this application specification and drawings, or direct or indirect applications in other related technical fields, are similarly included in the patent protection scope of this application.
