Description

Technical Field

[0001] The utility model relates to the field of kitchens and bathrooms, and in particular to a wire control component for a water discharge device and a water discharge device. Background Art

[0002] When using a sink in daily life, sometimes the sink is needed to store water. After use, it is necessary to open the sealing plug at the drain outlet to drain the water. At this time, we need to put our hands into the sewage to pull out the sealing plug to achieve drainage. However, putting our hands into the sewage will cause trouble to customers and is relatively dirty.

[0003] In response to the above problems, the Chinese invention patent application with patent number CN202310494448.2 (publication number CN116837944A) discloses "Wire-controlled switch and water discharge device". The wire-controlled switch includes a housing, a knob, a sliding member, a control wire core and a driving motor, and the knob is rotatably connected to the housing; the sliding member is arranged in the housing and slidably connected to the housing; one end of the control wire core is used to connect the sealing plug, and the other end is connected to the sliding member, and the control wire core can move with the movement of the sliding member; the driving motor includes a motor body and an output shaft, the output shaft is passed through the motor body, and both ends of the output shaft extend out of the motor body, one end of the output shaft is connected to the knob, and the other end is connected to the sliding member, and the rotation of the output shaft can drive the movement of the sliding member; in the first working mode of the wire-controlled switch, the motor body drives the output shaft to rotate, and in the second working mode, the knob drives the output shaft to rotate; the user can control the opening and closing of the water discharge port by electronic control or manual means, so that the wire-controlled switch can still be used normally in the case of power failure.

[0004] However, during the drainage process, the water flow will impact the sealing plug. The sealing plug will move downward under the action of the water flow and reversely drive the sliding member (equivalent to the moving rod below) to move upward, thereby causing the sealing plug to block the drain outlet and make it impossible to drain.

[0011] A wire core, the first end of which is connected to the moving rod, and the second end of which is used to drive the sealing plug of the water discharge device to move up and down;

[0012] It is characterized by that it also includes

[0013] The elastic member acts on the rotating rod to keep the first threaded portion and the second threaded portion in a tight relationship.

[0014] Preferably, one of the first threaded portion and the second threaded portion is a thread, and the other of the first threaded portion and the second threaded portion is a spiral groove for the thread to be embedded therein, and the cross-section of the thread is triangular, so that the first threaded portion and the second threaded portion have mechanical locking properties, further preventing the sealing plug from reversely driving the moving rod to move upward.

[0015] Furthermore, the first threaded portion and the second threaded portion adopt a triple-helix structure, so as to increase the friction between the first threaded portion and the second threaded portion and prevent the sealing plug from reversely driving the moving rod to move upward.

[0016] In order to ensure that the moving rod can only move up and down but not rotate in a circle, a vertically extending slide groove is provided on the inner wall surface of the shell, and a protrusion that can slide along the slide groove is provided on the moving rod; or, a protrusion is provided on the inner wall surface of the shell, and a vertically extending slide groove is provided on the moving rod, the protrusion can be placed in the slide groove and the two produce relative displacement in the vertical direction.

[0017] In order to facilitate the operation of the rotating rod, a knob is provided above the shell, and the knob is fixedly connected to the rotating rod through a connecting rod extending into the shell.

[0018] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a water discharge device, characterized in that: the water discharge device includes a water trough and a sealing plug, a water discharge port is provided on the bottom wall of the water trough, and the sealing plug is linked with the second end of the above-mentioned wire core to open or block the water discharge port.

[0019] The wire core can be directly connected to the sealing plug or can be driven indirectly. A vertically extending vertical rod is connected to the bottom wall of the sealing plug. The second end of the wire core is connected to the vertical rod through a linkage assembly, thereby driving the vertical rod to move up and down.

The rotation axes of the linkage rod, the first swing rod and the second swing rod all extend along the axial direction of the linkage rod. The knob controls the rotation of the rotating rod to drive the moving rod to move up and down. During the movement of the moving rod up and down, the wire core will be pulled to move along the guide cylinder, and the first swing rod is driven by the wire core to rotate, thereby driving the linkage rod to rotate around its axis. The second swing rod swings synchronously, driving the vertical rod to move up and down, so that the sealing plug moves up and down to open or close the drain.

[0021] Preferably, the drain port is connected to a drain pipe, the receiving box is mounted on the drain pipe, and the two are connected, and the second swing arm is at least partially located in the drain pipe.

[0024] In order to prevent the linkage rod from moving in the axial direction, a limiting rib capable of abutting against the linkage rod in the axial direction is provided in the accommodation box.

[0025] Compared with the prior art, the utility model has the following advantages: the utility model is provided with an elastic member acting on the rotating rod, and the elastic member makes the first threaded portion and the second threaded portion maintain a tendency to press against each other, so that when draining water, the sealing cover can be prevented from being impacted by the water flow, and the wire core is driven in the reverse direction, so that the wire core drives the moving rod to move upward, and drives the rotating rod in the reverse direction, so that the sealing cover blocks the drain outlet on the sink, and finally makes it impossible to drain water.

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] like Figures 1 to 8 As shown, the water discharge device of this preferred embodiment includes a water tank 1, a wire control assembly and a sealing plug 11. Figure 6 As shown, a water outlet 12 is provided on the bottom wall of the water tank 1 , and a sealing plug 11 can move up and down to open or block the water outlet 12 .

[0036] The wire control assembly includes a housing 2, a rotating rod 3, a moving rod 4, a wire core 5 and an elastic member 6. Figure 2 As shown, the shell 2 includes a cylinder 21 and an upper shell 22 and a lower shell 23 mounted on the cylinder 21. The upper shell 22 and the lower shell 23 are both threadedly connected to the cylinder 21. The rotating rod 3 and the moving rod 4 are both arranged in the cylinder 21. The upper shell 22 is located above the top wall of the water tank 1, and the lower shell 23 is located below the top wall of the water tank 1. Gaskets 24 are provided between the upper shell 22, the lower shell 23 and the top wall of the water tank 1 to prevent hard interference between components and cause wear of the components.

[0037] like Figures 2 to 4 As shown, the rotating rod 3 extends vertically and can rotate around its axis. The rotating rod 3 is provided with a first threaded portion 31. The moving rod 4 can move up and down. The moving rod 4 is plug-fitted with the lower end of the rotating rod 3. The moving rod 4 is provided with a second threaded portion 41 which can be threadedly connected with the first threaded portion 31.

[0038] A knob 7 is provided above the housing 2. The knob 7 is fixedly connected to the rotating rod 3 via a connecting rod 71 extending into the housing 2. By rotating the knob 7, the rotating rod 3 is driven to rotate, thereby causing the moving rod 4 to move up and down.

[0039] In order to make the moving rod 4 only move up and down but not rotate in the circumferential direction, a protrusion is provided on the inner wall surface of the housing 2, and a vertically extending slide groove 42 is provided on the moving rod 4, in which the protrusion can be placed and the two can generate relative displacement in the vertical direction. Alternatively, a vertically extending slide groove 42 is provided on the inner wall surface of the housing 2, and a protrusion that can slide along the slide groove 42 is provided on the moving rod 4.

[0040] The first end of the wire core 5 is connected to the moving rod 4, and the second end is used to drive the sealing plug 11 of the water discharge device to move up and down to open or block the water discharge port 12. Figures 5 to 8 As shown, a vertically extending vertical rod 15 is connected to the bottom wall surface of the sealing plug 11, and the second end of the wire core 5 is connected to the vertical rod 15 through a linkage assembly, thereby driving the vertical rod 15 to move up and down.

[0041] In this embodiment, the linkage assembly is arranged in a accommodating box 81, and the linkage assembly includes a guide cylinder 82, a linkage rod 83, a first swing rod 84 and a second swing rod 85. The guide cylinder 82 extends laterally and allows the second end of the wire core 5 to pass through. The lower end of the first swing rod 84 is connected to the second end of the wire core 5, the upper end of the first swing rod 84 is fixedly connected to the first end of the linkage rod 83, and the second end of the linkage rod 83 extends in the direction of the vertical rod 15. One end of the second swing rod 85 is fixedly connected to the second end of the linkage rod 83, and the free end of the second swing rod 85 is abutted against or connected to the bottom of the vertical rod 15. The rotation axes of the linkage rod 83, the first swing rod 84 and the second swing rod 85 all extend along the axial direction of the linkage rod 83. In this embodiment, the rotation axes of the three all extend in the horizontal direction.

[0042] The knob 7 controls the rotation of the rotating rod 3, driving the moving rod 4 to move up and down. During the up and down movement of the moving rod 4, the wire core 5 will be pulled to move along the guide tube 82. The first rocker arm 84 is driven by the wire core 5 to rotate, thereby driving the linkage rod 83 to rotate around its axis. The second rocker arm 85 swings synchronously, driving the vertical rod 15 to move up and down, causing the sealing plug 11 to move up and down, opening or closing the drain outlet 12.

[0043] Both ends of the wire core 5 are provided with connectors 51, and the connector 51 at the second end of the wire core 5 is installed in the first swing rod 84. An arc-shaped limiting groove 811 is provided in the position of the accommodating box 81 corresponding to the first swing rod 84, and the connector 51 can slide along the limiting groove 811. The limiting groove 811 not only guides the rotation trajectory of the first swing rod 84, but also limits the connector 51 from escaping from the first swing rod 84.

[0044] In order to prevent the linkage rod 83 from moving in the axial direction, a limiting rib 812 which can axially abut against the linkage rod 83 is provided in the accommodating box 81 .

[0045] The downspout 12 is connected to the downspout 14, the receiving box 81 is installed on the downspout 14, and the two are connected, and the second swing arm 85 is at least partially located in the downspout 14. In this way, the linkage assembly is located outside the downspout 12, does not occupy the space of the sink 1 and the downspout 12, and only the second swing arm 85 partially occupies the space of the downspout 14, which will not affect the normal drainage. A sealing ring 86 is provided between the linkage rod 83 and the inner wall surface of the receiving box 81 to prevent water in the downspout 14 from leaking into the receiving box 81.

[0046] In order to prevent the sealing plug 11 from driving the moving rod 4 in the reverse direction, Figure 2 As shown, the elastic member 6 acts on the rotating rod 3, so that the first threaded portion 31 and the second threaded portion 41 maintain a tendency to press against each other. In this embodiment, the elastic member 6 is a spring, and the housing 2 is provided with a receiving groove 13 for accommodating the spring, and the peripheral wall of the rotating rod 3 is provided with a stopper 32 that can abut against the end of the spring, so that the spring is in a compressed state. In addition, a guide member 61 is inserted into the receiving groove 13, and the guide member 61 can move up and down relative to the receiving groove 13. The upper part of the spring is installed in the guide member 61, and the guide member 61 abuts against the stopper 32.

[0047] The provision of the spring increases the friction between the threaded pair of the movable rod 4 and the rotating rod 3, preventing the wire core 5 from driving the movable rod 4 upward in the reverse direction under the impact force of the water in the sink 1, causing the sealing plug 11 to seal the drain outlet 12 and prevent water from being discharged. At the same time, the spring elastic force acts to enhance the customer's experience in operating the knob 7.

[0048] Preferably, one of the first threaded portion 31 and the second threaded portion 41 is a thread, and the other of the first threaded portion 31 and the second threaded portion 41 is a spiral groove for the thread to be embedded therein, and the cross-section of the thread is a triangle, preferably an equilateral triangle; the first threaded portion 31 and the second threaded portion 41 adopt a triple-helix structure, and these designs are all intended to further enable the first threaded portion 31 and the second threaded portion 41 to have mechanical locking properties to prevent the sealing plug 11 from reversely driving the moving rod 4 to move upward.

[0049] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
