Description

Technical Field

[0001] The utility model relates to the technical field of drains, in particular to a drain control mechanism and a water tank. Background Art

[0002] The existing way of draining the basin usually requires putting your hand directly into the water to release the sealing state of the basin piston. This method will cause the user's hand to be contaminated by the sewage in the basin, which is neither convenient nor hygienic. Therefore, people have designed a water discharge control mechanism, which refers to a motion mechanism that can switch the basin water storage and drainage states.

[0003] Existing drainage control mechanisms are generally divided into manual and electric types, which are mostly used in single-slot basin scenarios and cannot be applied to double-slot basin scenarios. Compared with a single-slot basin that has only two states, open and closed, a double-slot basin requires a mechanism to control the basin to be open on both sides, closed on both sides, open on the left and closed on the right, and open on the left and closed on the right, and be able to switch between these four states continuously and stably. In addition, the electric drainage control mechanism is prone to short-circuit failure due to the humid environment in which the basin is used, and has poor reliability. It may also be unable to perform the original water storage and drainage tasks due to power outages, resulting in a poor basin experience. Utility Model Content

[0034] Example 1

[0035] Combined with Figure 1-15The present embodiment provides a water discharge control mechanism, including a housing 10, a knob 11, a driving member 12, a driven member 13, a water discharge device shaft 14, a first push rod 15, a second push rod 16 and a shaft cover 17; the knob 11 is movably matched with the housing 10, the knob 11 is circumferentially fixedly connected with the driving member 12, and the driving member 12 is transmission-connected with the driven member 13; the shaft cover 17 is fixedly arranged on one side of the housing 10, and the water discharge device shaft 14 is at least partially located on the shaft cover 17 In the embodiment, one end of the drain shaft 14 is connected to the driven member 13 in a transmission manner; a limited portion 18 is provided on the shaft cover 17 and / or the housing 10, and the first push rod 15 and the second push rod 16 are both slidably matched with the corresponding limited portion 18; a first slider 201 is provided on the first push rod 15, and a second slider 202 is provided on the second push rod 16; a slide 19 is provided on the drain shaft 14, and the slide 19 includes a first state segment 191, a second state segment 192 and a transition segment 193. Segment 193, the spacing between the first state segment 191 and the follower 13 is smaller than the spacing between the second state segment 192 and the follower 13; the first state segment 191 and the second state segment 192 are connected by the transition segment 193 to form a slideway 19 that surrounds the circumference of the water discharger shaft 14; the first slider 201 and the second slider 202 are both movably matched with the first state segment 191, the second state segment 192 and the transition segment 193, so that the first push rod 15 and the second push rod 16 can move translationally along the limiting portion 18, and form the following working conditions: the first slider 201 and the second slider 202 are both located in the first state segment 191; or the first slider 201 and the second slider 202 are both located in the second state segment 192; or the first slider 201 is located in the first state segment 191, and the second slider 202 is located in the second state segment 192; or the first slider 201 is located in the second state segment 192, and the second slider 202 is located in the first state segment 191.

[0036] A drain control mechanism of the present embodiment is applied to a sink with double basins. Power is transmitted between the knob 11, the driving member 12, the follower 13 and the drain shaft 14 to drive the first push rod 15 and the second push rod 16 to perform corresponding translational activities along the travel of the slide 19, thereby realizing independent opening and closing control of the drain outlets 39 of the basins 38 on both sides.

[0037] A water discharge control mechanism of the present embodiment has the following working principle: a first push rod 15 and a second push rod 16 are respectively connected to the drain water seals 40 of the basins 38 on both sides through a pull rope 41. When in use, the operator rotates the knob 11 to drive the drain shaft 14 to rotate through the driving member 12 and the driven member 13. During the rotation, the inner wall of the slide 19 will exert a force on the first slider 201 and the second slider 202 to make the first slider 201 and the second slider 202 slide along the extension direction of the slide 19. Since the first push rod 15 and the second push rod 16 are both limited by the limiting part 18, the sliding of the first slider 201 and the second slider 202 will be converted into the translational motion of the first push rod 15 and the second push rod 16.

[0038] Since the slideway 19 of the present embodiment is composed of the first state section 191 , the second state section 192 and the transition section 193 , as the knob 11 rotates, four matching conditions of the first slider 201 and the second slider 202 with the slideway 19 can be realized.

[0039] In one embodiment, the first slider 201 and the second slider 202 are defined as being in the first state segment 191, which is the state in which the first push rod 15 and the second push rod 16 pull the pull rope 41, at which time the corresponding drain water seal 40 is pulled open, and the corresponding trough 38 can achieve simultaneous drainage of the left and right troughs. At the same time, the first slider 201 and the second slider 202 are defined as being in the second state segment 192, which is the state in which the first push rod 15 and the second push rod 16 do not pull the pull rope 41, at which time the corresponding drain water seal 40 is not pulled open, and the corresponding trough 38 cannot achieve drainage of the left and right troughs.

[0040] In the above implementation mode, the launching conditions corresponding to the four working conditions of this embodiment are as follows:

[0041] like Fig.11 As shown, when the first slider 201 and the second slider 202 are both located in the first state section 191, the first push rod 15 and the second push rod 16 will pull the corresponding pull rope 41, so that the drain water seals 40 of the left and right basins 38 are both opened, and the basins 38 on the left and right sides can now drain.

[0042] like Fig.12 As shown, when the first slider 201 and the second slider 202 are both located in the second state section 192, the first push rod 15 and the second push rod 16 do not pull the corresponding pull rope 41, so that the drain water seals 40 of the left and right basins 38 are not opened, and at this time, the left and right basins 38 cannot be drained.

[0043] like Fig.13As shown, when the first slider 201 is in the first state section 191 and the second slider 202 is in the second state section 192, only the pull rope 41 corresponding to the first push rod 15 is pulled, that is, only the drain water seal 40 corresponding to the first push rod 15 of the trough 38 on one side is pulled open, and the drain water seal 40 of the trough 38 on the other side is not pulled open, thereby realizing the working condition that the trough 38 on one side is drained while the trough 38 on the other side is not drained.

[0044] like Fig.14 As shown, when the first slider 201 is located in the second state segment 191 and the second slider 202 is located in the first state segment 192, only the pull rope 41 corresponding to the second push rod 16 is pulled, that is, only the drain water seal 40 corresponding to the second push rod 16 of the trough 38 on one side is pulled open, and the drain water seal 40 of the trough 38 on the other side is not pulled open, thereby realizing the opposite working condition of the previous condition, that is, water is discharged from the trough on one side while water is not discharged from the trough on the other side.

[0045] Thus, the first push rod 15 and the second push rod 16 can pull the pull rope 41 or release the pull rope 41, thereby driving the water seal 40 of the drain in the two side basins 38 to close and open the drain port 39, respectively, to achieve the drainage control of the two side basins 38. In a conceivable embodiment, the limiting portion 18 is a limiting slideway or guide groove or other structure provided on the rotating shaft cover 17 or the housing 10, and slidably cooperates with the outer wall of the slider 20 to achieve the limiting effect.

[0046] In this embodiment, the driving member 12 and the driven member 13 can be components with a spur gear meshing form, or components with a helical gear meshing form. In a preferred embodiment, the driving member 12 and the driven member 13 are provided with mutually meshing bevel gear tooth profiles, so that the driving member 12 and the driven member 13 constitute a bevel gear meshing transmission structure. In this case, the knob 11 is connected to the driving member 12 and drives the driving member 12 to rotate, and the bevel gear tooth profile of the driving member 12 and the bevel gear tooth profile of the driven member 13 are mutually meshed and transmitted, thereby driving the water discharger shaft 14 to rotate, and then controlling the telescopic movement of the first push rod 15 and the second push rod 16, so as to control the opening and closing state of the water discharger drain port 39. In this preferred embodiment, the bevel gear meshing transmission structure formed by the driving member 12 and the driven member 13 realizes the steering of power transmission, which is conducive to reducing the one-way length of the water discharge control mechanism and improving the rationality of the layout.

[0047] There is a transmission connection between the drain shaft 14 and the driven member 13. The specific form of the transmission connection is not limited. It can be a form in which the drain shaft 14 and the driven member 13 are directly fixedly connected, or a meshing structure such as a spline, gear, worm gear, or other transmission structure can be set between the drain shaft 14 and the driven member 13 to achieve a transmission connection between the drain shaft 14 and the driven member 13.

[0048] Example 2

[0049] Combined with Figure 1-2 Compared with the technical solution of Example 1, a launching control mechanism of this embodiment can be improved as follows: a positioning column 21 is provided on one of the knob 11 and the driving member 12, and a knob positioning hole 22 is provided on the other; the knob positioning hole 22 and the positioning column 21 are interference fit; a positioning groove 23 is provided on one of the positioning column 21 and the knob positioning hole 22, and a positioning rib 24 is provided on the other; the positioning groove 23 and the positioning rib 24 cooperate with each other.

[0050] In this embodiment, the fixed connection between the knob 11 and the driving member 12 is achieved by the interference fit between the positioning column 21 and the knob positioning hole 22. Furthermore, the positioning column 21 and the knob positioning hole 22 are further positioned and fixed by the mutually engaged positioning ribs 24 and positioning grooves 23. In a more preferred embodiment, two positioning grooves 23 are provided on the positioning column 21, which cooperate with the two positioning ribs 24 on the inner wall of the knob positioning hole 22 of the driving member 12, so that when the knob 11 is rotated, the driving member 12 can be better driven to rotate together, ensuring that there is no relative rotation between the knob 11 and the driving member 12.

[0051] Example 3

[0052] Combined with Figure 1-4 Compared with the technical solutions of Examples 1 or 2, a launching control mechanism of this embodiment can be improved as follows: an origin slot 25 and a plurality of positioning slots 26 are circumferentially arranged on the driving member 12, and a protruding elastic member 27 is arranged in the shell 10. The protruding elastic member 27 is matched with the positioning slot 26 and the origin slot 25 to position the rotation of the driving member 12.

[0053] In this embodiment, the driving member 12 is provided with an origin slot 25 and at least three positioning slots 26 in the circumference thereof for cooperating with the raised elastic member 27 for positioning to prevent the driving member 12 from continuing to rotate and to maintain the pulling of the water seal 40 in a specific state.

[0054] When in use, the protruding elastic member 27 is generally selected to be a bent spring sheet. When the spring sheet contacts the outer edge of the driving member 12, the spring sheet is in a state of force compression. As the driving member 12 rotates, when the spring sheet falls to the position of the origin slot 25 or the positioning slot 26, the spring sheet rebounds and is stuck in the origin slot 25 or the positioning slot 26, generating resistance to the rotation of the driving member 12, preventing the driving member 12 from continuing to rotate, thereby maintaining the retracted or extended state of the first push rod 15 or the second push rod 16 at this moment, that is, maintaining the state in which the water seal 40 in the two side basins 38 is pulled up or not pulled up. In a conceivable embodiment, in addition to an origin slot 25 on the driving bevel gear for maintaining the initial state in which the two side basins 38 are opened at the same time, three positioning slots 26 can also be provided, which are respectively used to maintain the two side basins 38 opened respectively, or the two side basins 38 closed at the same time.

[0055] Example 4

[0056] Combined with Figure 1-5 Compared with the technical solution of Example 3, the water launching control mechanism of this embodiment can be improved as follows: a baffle 28 is provided at the positioning slot 26, and the baffle 28 is located on the side of the positioning slot 26 facing the knob 11.

[0057] In this embodiment, a baffle 28 is provided at each positioning slot 26, but not at the origin slot 25. The purpose is that when assembling the driving member 12, the protruding elastic member 27 needs to be placed in the housing 10 first, and then the driving member 10 is placed in the housing 10. When the baffle 28 is provided on the side of the positioning slot 26 facing the knob 11, if the baffle 28 abuts against the protruding elastic member 27, the positioning slot 26 will be unable to be installed due to the interference between the baffle 28 and the protruding elastic member 27. Figure 5 The figure below is a schematic diagram of the situation where interference occurs. Figure 4 As shown, only the origin slot 25 without the baffle 28 will not abut against the raised elastic member 27. Therefore, the interference design of the positioning slot 26 and the baffle 28 makes the initial position of the driving member 12 uniquely determined, that is, it is ensured that the origin slot 25 is matched with the raised elastic member 27 at the beginning, then when the matching condition of the slider 20 and the slideway 19 on the first push rod 15 and the second push rod 16 remains unchanged, the initial position of the push rod is also determined, which effectively ensures the uniformity and certainty of the water storage and drainage state of the basin 38 after assembly.

[0058] Example 5

[0059] Combined with Figure 1 , 6and 7. A water launching control mechanism of the present embodiment, compared with the technical solution of embodiment 4, can be improved as follows: a connecting column 29 is provided on the water launcher shaft 14, the water launcher shaft 14 is fixedly connected to the follower 13 through the connecting column 29, a positioning member 30 is provided on the connecting column 29, a shaft positioning hole 31 is provided on the shell 10, and the positioning member 30 is matched with the shaft positioning hole 31.

[0060] In this embodiment, the fixed connection between the drain shaft 14 and the driven member 13 is achieved by the connecting column 29 , and the connecting column 29 and the driven member 13 may be interference fit.

[0061] In this embodiment, a positioning member 30 is provided on the connecting column 29, and a corresponding shaft positioning hole 31 is provided on the housing 10 to achieve the determination of the initial position of the drain shaft 14. Taking a feasible implementation example, a water drop-shaped opening is provided on the housing 10, and the contour of the positioning member 30 is consistent with the water drop-shaped opening. Therefore, only when the connecting column 29 of the drain shaft 14 is rotated to a certain angle to ensure that the positioning member 30 can just pass through the shaft positioning hole 31, the drain shaft 14 and the follower 13 can be fixedly connected. Therefore, based on the matching structure of the positioning member 30 and the shaft positioning hole 31, the initial relative position of the follower 13 and the drain shaft 14 is uniquely determined during assembly. On the basis of the initial position determination of the driving member 12 in the aforementioned embodiment, this embodiment further effectively ensures the uniformity and certainty of the water storage and drainage state of the basin 38 after assembly.

[0062] Example 6

[0063] Combined with Figure 1 , 8 and 9. A launching control mechanism of the present embodiment, compared with any one of the technical solutions of embodiments 1-5, can be improved as follows: a fixed plate 32 is fixedly connected to the shell 10, the knob 11 rotates around the center of the fixed plate 32, a status identification portion 42 is provided on the fixed plate 32, and an indication portion 43 is provided on the knob 11.

[0064] The fixed plate 32 in this embodiment is used to indicate the working condition of the water discharge control mechanism. In a preferred embodiment, the fixed plate 32 is provided with state marking parts 42 of four different states: left and right basins fully open, left and right basins fully closed, left basin closed and right basin open, and left basin open and right basin closed. An indication part 43 such as an indication point is provided on the drain knob 11. After rotating the drain knob 11, the indication point will point to the state marking part 42 on the fixed plate 32, thereby determining the water storage or drainage state of the left and right basins 38.

[0065] Example 7

[0066] Combined with Figure 1 and 9Compared with the technical solution of Example 6, a launching control mechanism of this embodiment can be improved as follows: one of the fixed plate 32 and the shell 10 is provided with a fixed column 33, and the other is provided with a hollow guide column 34, the fixed column 33 and the hollow guide column 34 are plugged together, one of the fixed column 33 and the hollow guide column 34 is provided with a guide rib 35, and the other is provided with a guide groove 36, and the guide rib 35 and the guide groove 36 cooperate with each other.

[0067] In this embodiment, the fixed connection between the fixed plate 32 and the housing 10 is achieved by interference fit between the fixed column 33 and the hollow guide column 34. To ensure a further stable arrangement of the fixed plate 32, guide ribs 35 and guide grooves 36 are respectively provided on the fixed column 33 and the hollow guide column 34. The engagement and positioning of the guide ribs 35 and the guide grooves 36 ensure that the assembled fixed plate 32 is in a relatively static state and does not rotate with the knob 11.

[0068] Example 8

[0069] Combined with Figure 1 and 10 Compared with any one of the technical solutions in Examples 1-7, a water discharge control mechanism of this embodiment can be improved as follows: it also includes a discharge nut 37, which is located between the knob 11 and the housing 10. A threaded hole is provided on the housing 10, and the discharge nut 37 is threadedly matched with the threaded hole.

[0070] In this embodiment, the drain nut 37 is installed above the table top of the basin 38, and the shell 10 is installed below the table top of the basin 38. The drain nut 37 and the shell 10 are connected by a thread. Therefore, the threaded connection between the drain nut 37 and the shell 10 provides a pre-tightening force, thereby firmly fitting the water discharge control mechanism to the table top of the basin 38, so that the water on the basin 38 cannot enter the interior of the water discharge control mechanism.

[0071] Example 9

[0072] Combined with Figure 1-15 A water sink in this embodiment includes a water discharge control mechanism of any technical solution of embodiments 1-9 and two troughs 38, each trough 38 is provided with a drain port 39, a water seal 40 is provided at the drain port 39, and the first push rod 15 and the second push rod 16 are respectively connected to each water seal 40 through a pull rope 41.

[0073] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
