DETAILED DESCRIPTION
[0026] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0027] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] See also Figure 1-Figure 5 The utility model discloses a drainage assembly, including a drainage housing 10, a blocking member 20 and a driving mechanism 30. A flow guiding cavity 13, a first conduction port 11 and a second conduction port 12 are provided in the drainage housing 10. The first conduction port 11 and the second conduction port 12 can be used as a water outlet and a water inlet, or as a water inlet and a water outlet, respectively. In this embodiment, the first conduction port 11 is used as a water outlet, and the second conduction port 12 is used as a water inlet. Both the first conduction port 11 and the second conduction port 12 are connected to the flow guiding cavity 13.
[0030] In addition, the blocking member 20 is arranged in the diversion cavity 13, and driven by the driving mechanism 30, the blocking member 20 can move close to or away from the first conduction port 11 to block or open the first conduction port 11. Specifically, the driving mechanism 30 includes a motor 31 and a linkage member, one end of the linkage member is connected to the rotating shaft of the motor 31, and the other end of the linkage member is rotatably connected to the blocking member 20 through a connecting shaft, and the connecting shaft and the rotating shaft of the motor 31 are eccentrically arranged, and when the rotating shaft of the motor 31 rotates, the linkage member can be driven to rotate, and the other end of the linkage member is rotatably connected to the blocking member 20, so that when the linkage member rotates, since the blocking member 20 is arranged in the diversion cavity 13, the swinging motion is restricted, so it can move close to or away from the first conduction port 11 along the diversion cavity 13 under the action of the linkage member.
[0031] Based on the above structure, when using the drainage component in the present application, taking the application of the drainage component to the drain outlet of the washing machine as an example, the second conductive port 12 can be connected to the drain outlet of the washing machine through a pipe joint, and the first conductive port 11 can be connected to the external drainage pipe.
[0032] When the washing machine is washing normally, the blocking member 20 can be in a blocking state close to the first conduction port 11. When draining water, the motor 31 can be started, and the rotating shaft of the motor 31 can drive the linkage member to rotate. Since the connecting shaft that is rotatably connected to the blocking member 20 and the rotating shaft of the motor 31 are eccentrically arranged, when the motor 31 drives the linkage member to rotate, the linkage member can swing, and the blocking member 20 is rotatably connected to the linkage member, so the swinging movement of the linkage member can link the blocking member 20 with the linear movement along the diversion cavity 13 under the restriction of the diversion cavity 13, realize the movement away from the first conduction port 11, and then open the first conduction port 11, so that the water flow introduced into the diversion cavity 13 from the second conduction port 12 can be discharged through the first conduction port 11 to realize drainage.
[0033] Since the movement of the blocking member 20 away from the first conducting port 11 is controlled by the linear movement of the blocking member 20 , the position of the blocking member 20 away from the first conducting port 11 can be controlled to achieve partial or full opening of the first conducting port 11 , thereby facilitating control of the drainage volume.
[0034] After the drainage action is completed, the shaft of the motor 31 can be rotated in the reverse direction, and the linkage member swings in the reverse direction, thereby driving the blocking member 20 connected thereto to move closer to the first conducting port 11 until the first conducting port 11 is blocked.
[0035] In this way, in this embodiment, by controlling the forward or reverse rotation of the rotating shaft of the motor 31, the movement of the blocking member 20 in the diversion cavity 13 is realized, and the opening or blocking action of the first conducting port 11 is realized, and the movement stroke of the blocking member 20 can be controlled by controlling the rotation range of the rotating shaft of the motor 31, and the opening speed of the blocking member 20 can also be achieved by controlling the rotation speed of the motor 31 to prevent the discharge water flow from being too fast.
[0036] Of course, the linkage member can also be realized by using a cam structure in the prior art in combination with a connecting rod structure, and any transmission structure that converts rotational motion into linear motion can be used. In addition, the drainage assembly can also be used in the drainage structure of a kitchen drain pipe, or the drainage structure position of a water purifier that needs to drain sewage, and any equipment that needs drainage control can be used.
[0037] Furthermore, the linkage member in the present embodiment includes a first swing arm 32 and a second swing arm 33, and one end of the first swing arm 32 is connected to the rotating shaft of the motor 31, while the other end of the first swing arm 32 is rotatably connected to one end of the second swing arm 33, and the other end of the second swing arm 33 is rotatably connected to the blocking member 20 via a connecting shaft. In this way, when the blocking member 20 is driven to move, the rotation of the motor 31 can drive the first swing arm 32 to swing, and then link the second swing arm 33 to swing, thereby linking the blocking member 20 to approach or move away from the first conducting port 11, and linking the blocking member 20 with the swing of the first swing arm 32 and the second swing arm 33, so that the swing range formed in this way is larger, and therefore the movement stroke of the blocking member 20 is larger.
[0038] In addition, compared with using one swing arm to achieve the movement of the blocking member 20, the rotational coordination of two swing arms is more flexible and less likely to get stuck.
[0039] Furthermore, in order to facilitate the assembly of the first swing arm 32 and the second swing arm 33, a first connecting piece can be provided on the first swing arm 32, and a second connecting piece can be provided on the second swing arm 33. In this way, the first connecting piece and the second connecting piece of the first swing arm 32 and the second swing arm 33 can be made to correspond to each other, and the second connecting piece can be connected to the first connecting piece. Specifically, the detachable connection between the first connecting piece and the second connecting piece can be achieved by bolts, screws or plug-in matching, or by a hinge shaft or the like.
[0040] Embodiment 1,
[0041] See also Figure 1 , Figure 2 as well as Figure 3This embodiment provides a drainage component, taking the example that the first connecting member includes a connecting column 321 and the second connecting member includes a connecting hole 331. When the first swing arm 32 and the second swing arm 33 are assembled, the connecting column 321 can be inserted into the connecting hole 331 to achieve the assembly of the two.
[0042] Specifically, in order to prevent the first swing arm 32 and the second swing arm 33 from detaching after assembly, a limit block 322 can be provided on the connecting column 321, and a connecting notch 332 can be provided corresponding to the connecting hole. During assembly, the limit block 322 of the connecting column 321 can be first aligned with the connecting notch 332 of the connecting hole, and then the limit block 322 can be extended through the connecting notch 332 to guide the connecting column 321 to be connected to the connecting hole 331. After being connected to the connecting hole 331, the connecting column 321 is rotated to stagger the limit block 322 and the connecting notch 332, so that the limit block 322 can be against the end face of the second swing arm 33 to prevent detachment.
[0043] By adopting the assembly method in this embodiment, the two swing arms can be assembled without using bolts or screws. In this way, the assembly process can be completed without the help of external wrenches or screwdrivers, making the assembly convenient and simple.
[0044] Of course, a limit block 322 structure can also be set on the inner wall of the connecting hole, and a corresponding through-notch 332 structure can be set on the side wall of the connecting column 321, so that during assembly, the limit block 322 structure of the connecting hole can be inserted into the through-notch 332 accordingly, and then rotated and staggered.
[0045] Furthermore, in order to prevent the connecting column 321 from protruding from the end surface of the second swing arm 33 after being assembled with the connecting hole 331, a connecting groove 333 may be provided on the second swing arm 33, and the connecting hole 331 is provided in the connecting groove 333. On this basis, the stopper 322 is offset from the penetration notch 332 and abuts against the bottom wall of the connecting groove 333. In this way, when the first swing arm 32 and the second swing arm 33 are assembled, the stopper 322 of the connecting column 321 corresponds to the penetration notch 332 of the connecting hole 331, the connecting column 321 is penetrated into the connecting hole 331, the stopper 322 is penetrated to the top of the connecting hole 331, and then offset from the penetration notch 332 and abuts against the penetration notch 332 to prevent detachment. The end of the connecting column 321 that passes through the connecting hole 331 can be received in the connecting groove 333 to prevent protrusion.
[0046] It should also be noted that the above-mentioned limit block 322 and the through-notch 332 can be rotated in a relatively large range, while the second swing arm 33 has a relatively small swing range when swinging to drive the blocking member 20 to move, so the second swing arm 33 is reasonably set to be staggered with the limit block 322 when swinging. When disassembly is required, the second swing arm 33 or the connecting column 321 of the first swing arm 32 can be manually rotated to the corresponding position of the limit block 322 and the through-notch 332 for disassembly.
[0047] Embodiment 2,
[0048] Further, see Figure 4 as well as Figure 5 In the drainage assembly shown in the embodiment, the first connecting member includes a connecting column 321, and the second connecting member includes a connecting hole 331. When the first swing arm 32 and the second swing arm 33 are assembled, the connecting column 321 can be inserted into the connecting hole 331 to achieve the assembly of the two. However, different from the above-mentioned embodiment 1, after the connecting column 321 is inserted into the connecting hole 331, in order to prevent the first swing arm 32 and the second swing arm 33 from being separated, a bolt 325 can be connected to lock the connecting column 321 and the second swing arm 33. Specifically, the head of the bolt abuts against the end face of the second swing arm 33, and the connecting hole 331 is a threaded hole. The tail of the bolt is screwed into the threaded hole and screwed into the connecting column 321. When swinging, the bolt can prevent the two from being separated. At the same time, the second swing arm 33 can swing with the connecting column 321 as the rotation axis.
[0049] Embodiment 3,
[0050] Based on the structures of Examples 1 and 2, the blocking member 20 in this embodiment includes a blocking rod 21 and a flexible blocking head 22. One end of the blocking rod 21 is linked to a linkage member, and the other end of the blocking rod 21 is provided with a flexible blocking head 22. The flexible blocking head 22 is used to seal and block the first conducting port 11. In this way, when the rotating shaft of the motor 31 rotates, the linkage member can be driven to swing through the rotating shaft of the motor 31, thereby linking the blocking rod 21 to perform sealing or opening.
[0051] Since a flexible sealing head 22 is provided at the end of the sealing rod 21, the first conducting port 11 is sealed with the flexible sealing head 22 during sealing. The flexible sealing head 22 can be deformed when subjected to force and seal to the inner wall or outer periphery of the first conducting port 11, thereby achieving a good sealing effect and preventing water leakage.
[0052] Of course, the flexible plugging head 22 can be implemented by using a rubber plug or a silicone plug in the prior art. In addition, a multi-layer sealing ring structure can be provided on the outer wall of the end of the plugging rod 21 to achieve sealing and plugging, and the specific selection and setting can be made according to actual needs.
[0053] Furthermore, the sealing member 20 also includes a threaded hose 23, which is sleeved on the outside of the sealing rod 21; the end of the sealing rod 21 extends out of the end of the threaded hose 23 and is connected to the flexible sealing head 22; the flexible sealing head 22 is used to compress the threaded hose 23 when moving away from the first conducting port 11. Based on this structure, since the flexible sealing head 22 passes through the threaded hose 23, when the sealing rod 21 pulls the flexible sealing head 22 away from the first conducting port 11, the sealing rod 21 can move inside the threaded hose 23, so that the flexible sealing head 22 outside can compress the threaded hose 23. During the compression of the threaded hose 23, the air and seepage inside the diversion cavity 13 can be discharged.
[0054] Embodiment 4,
[0055] A washing machine includes the drainage assembly in any one of Embodiments 1, 2 and 3, wherein the second conduction port 12 is connected to the drainage port of the washing machine. When the washing machine is performing a normal machine washing action, the blocking member 20 may be in a blocked state close to the first conduction port 11. When performing a drainage action, the motor 31 may be started, and the rotating shaft of the motor 31 may drive the linkage member to rotate. Since the connecting shaft that is rotatably connected to the linkage member and the blocking member 20 is eccentrically arranged with the rotating shaft of the motor 31, when the motor 31 drives the linkage member to rotate, the linkage member may swing, and the blocking member 20 is rotatably connected to the linkage member, so that the swinging motion of the linkage member may link the blocking member 20 with the linear motion along the diversion cavity 13 under the restriction of the diversion cavity 13, realize the motion away from the first conduction port 11, and then open the first conduction port 11, so that the water flow introduced into the diversion cavity 13 by the second conduction port 12 may be discharged through the first conduction port 11, and realize drainage.
[0056] Since the movement of the blocking member 20 away from the first conducting port 11 is controlled by the linear movement of the blocking member 20 , the position of the blocking member 20 away from the first conducting port 11 can be controlled to achieve partial or full opening of the first conducting port 11 , thereby facilitating control of the drainage volume.
[0057] After the drainage action is completed, the shaft of the motor 31 can be rotated in the reverse direction, and the linkage member swings in the reverse direction, thereby driving the blocking member 20 connected thereto to move closer to the first conducting port 11 until the first conducting port 11 is blocked.
[0058] In this way, in this embodiment, by controlling the forward or reverse rotation of the rotating shaft of the motor 31, the movement of the blocking member 20 in the diversion cavity 13 is realized, and the opening or blocking action of the first conducting port 11 is realized, and the movement stroke of the blocking member 20 can be controlled by controlling the rotation range of the rotating shaft of the motor 31, and the opening speed of the blocking member 20 can also be achieved by controlling the rotation speed of the motor 31 to prevent the discharge water flow from being too fast.
[0059] The drainage component in this embodiment is the same as the above-mentioned embodiments 1, 2 and 3, and its structure and effect on the washing machine will not be described in detail here. The other structures of the washing machine are existing technologies and will not be described in detail here.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
