The plug cover 51 is provided with a body and an extension. The body is in a disc shape bent upwards as shown in the figure, the extending part is in a ring shape, and the upper end of the extending part is fixedly connected with the lower surface of the body. The outer wall of the extension part is provided with a sealing ring groove. The stem 52 extends downward from the center of the lower surface of the body. Lip seal 53 is disposed in the seal groove and opens outwardly. As shown in fig. 4 and 5, the valve stem 52 of the plug 5 is inserted into the valve stem hole 24 below the water collection opening 22 of the valve housing 2, so that the plug 5 and the valve housing 2 are slidably connected to each other in a vertical direction with respect to the valve housing 2, and fig. 4 shows a state in which the plug 5 is located at a high position, at which the plug 5 opens the water collection opening 22. Fig. 5 shows the plug 5 in a lowered position, in which the plug 5 blocks the water collection opening 22. When the plug 5 plugs the water collection opening 22, the lip-shaped sealing ring 53 abuts against the side wall of the water collection opening 22 to form a seal.

The overflow cover 6 is shaped as shown in fig. 6. A rotating shaft 62 extending backwards is arranged at the center of the rear end face of the overflow cover 6, and the axis of the rotating shaft 62 is coincided with the axis of the overflow cover 6. The rotating shaft 62 is adapted to be inserted into the rotating shaft hole 18 of the overflow base 1. The front end surface of the overflow cover 6 is further provided with a handle 61 away from the axis thereof for operating the overflow cover 6 to rotate about the axis thereof. Fig. 7 shows the relationship with the overflow 11 when the overflow cover 6 is rotated to the first position about its rotation axis, and fig. 8 shows the relationship with the overflow 11 when the overflow cover 6 is rotated to the second position about its rotation axis. As shown in fig. 7, when the overflow cover 6 is rotated to the first position, it shields the overflow gate 11, and the handle 61 is positioned in the lower right direction. At this time, if the overflow cover 6 is rotated to the second position shown in fig. 8 by operating the handle 61 in the counterclockwise direction as shown in fig. 7, the overflow cover 6 shields only a small portion of the overflow 11, and both the large portion of the overflow 11 and the water outlet 16 are opened. At this time, the handle 61 is positioned in the upper left direction. At this time, if the overflow cover 6 is rotated to the first position shown in fig. 7 by operating the handle 61 in the clockwise direction as shown in fig. 8, the overflow cover 6 will again cover the overflow 11.

The components of the transmission member 7 are shown in fig. 9 and 10. As shown, the transmission member 7 includes a gear 71, a rack 72, a rotor 73, a wire cover 74 and a brake wire 75. The gear 71 is connected to the rotation shaft 62 in a rotation-stopping manner as shown in fig. 6, and is driven to rotate around the axis of the overflow cover 6 by the overflow cover 6. The gear 71 is adapted to be received in the gear cavity of the spill seat 1. A rack 72 is provided in the vertical direction, engaged with the gear 71, and adapted to be received in a rack chamber of the overflow water base 1. The rotor 73 includes a rotor shaft 731, a paddle 732 radially disposed on an outer wall of the rotor shaft 731, and a tension bar 733 radially disposed on the outer wall of the rotor shaft 731. The shifting piece 732 and the pulling rod 733 form a shifting angle therebetween and are respectively located at different positions of the rotor shaft 731 along the length direction. Wherein the rotor shaft 731 is adapted to be placed in the rotor bore 25 of the valve housing 2, and the axis of rotation of the rotor shaft 731 is perpendicular to the sliding direction of the valve stem 52. The upper surface of the pick 732 pushes up against the bottom end of the valve stem 52 for converting the rotation of the rotor shaft 731 into the up-and-down movement of the valve stem 52. The pull rod 733 is used to drive the rotor shaft 731 to rotate. The wire sleeve is fixed relative to the overflow base 1 at one end and is arranged below the rack cavity 19 as shown in figure 1. The other end is fixed relative to the valve casing 2 and arranged behind the connecting cavity. One end of the brake cable 75 is clamped with the lower end of the rack 72, and the other end is connected with the pull rod 733 in the connecting cavity. The brake cable 75 is used for driving the pull rod 733 to rotate.

Fig. 9 shows the state of the transmission member 7 and the state of the plug 5 when the overflow cover 6 is in the first position. As shown in fig. 9, at this time, the rack 72 is at a higher position due to the engagement with the gear 71 and abuts against the first limiting surface, the brake cable 75 is pulled to lift upward, the pull rod 733 is pulled backward, the rotor shaft 731 is driven to rotate until the shifting piece 732 is at a higher position, and the valve rod 52 abuts against the higher position, so that the plug 5 opens the water collecting port 22 of the valve housing 2.

Fig. 10 shows the state of the transmission member 7 and the state of the plug 5 when the overflow cover 6 is in the second position. As shown in fig. 10, at this time, the rack 72 is at a lower position due to being engaged with the gear 71 and abuts against the second limiting surface (since the gear 71 rotates counterclockwise when the overflow cover 6 rotates from the first position to the second position, the rack 72 is driven to descend), the brake cable 75 is pushed to extend downward, the pull rod 733 is pushed forward, the rotor shaft 731 is driven to rotate to the lower position of the shifting piece 732, the valve rod 52 is lowered to the lower position under the action of its own gravity, and the plug 5 plugs the water collection port 22 of the valve housing 2. At this time, if the overflow cover 6 is rotated clockwise to the first position, the rack 72 will return to the upper position as shown in fig. 9 and abut against the first stopper surface.

Therefore, the rotation and the reverse rotation of the overflow cover 6 can drive the rack 72 to move up and down, thereby driving the rotor 73 to rotate, and the shifting piece 732 drives the valve rod 52 to move up and down, so that the plug 5 opens or blocks the water collecting opening 22.

Fig. 11 and 12 show a bathtub 1000 in the present embodiment. As shown, the bathtub 1000 includes a bathtub body 200 and the bathtub drain 100 described above. The overflow seat 1 is fixedly connected with the bathtub body 200, and the overflow port 11 is arranged on the side wall 201 of the bathtub body; the valve casing 2 is fixedly connected with the bathtub body 200, and the water collecting opening 22 is arranged on the bottom wall 202 of the bathtub body. In this embodiment, the water inlet 15 is also connected with the water inlet pipe of the bathtub in a butt joint mode, and the on-off valve of the water inlet pipe controls water outlet or water cut-off.

In the solution of the present embodiment, since the overflow cover 6 is rotated along the first axis parallel to the axis of the overflow 11, i.e., its rotation axis is offset from the axis of the overflow 11. Therefore, when the overflow cover 6 is rotated to open the overflow 11, the opening area of the overflow 11 is large, increasing the overflow flow rate. On the other hand, the rotation of the overflow cover 6 is transmitted to the plug 5 to drive the plug 5 to open and close the water collecting opening 22, so that the integration of the overflow function and the drainage control function is realized. Moreover, in the present application, the opening and closing of the overflow 11 and the opening and closing of the water collection opening 22 are interlocked, that is, the water collection opening 22 is opened, and the overflow 11 is closed; the water collection opening 22 is closed and the overflow opening 11 is opened. Compared with the prior art, the design that the overflow opening 11 is always open has great benefit, namely, the user can determine the opening and closing state of the water collecting opening 22 by observing the relative position of the overflow cover 6 and the overflow opening 11. The present embodiment also integrates a three-in-one function, i.e., integrating the water intake function into the bathtub drainer 100. In the present application, since the axis of the water outlet 16 is parallel to the axis of the overflow 11, the water velocity of the water outlet 16 can be directly known by observing the length and strength of the water ejected from the water outlet. Of course, this also provides an advantage in that the pattern of the sprayed water can be changed by further integrating various water pattern changing devices. For example, in the present embodiment, a bubbler 17 is provided in the water outlet 16, so that bubble water can be obtained when water is replenished into the inner cavity of the bathtub. In this embodiment, the overflow cover 6 is provided with a handle 61, which is more convenient for the user to operate. In the embodiment, the partition plate 26 is arranged, and the upper edge of the water passing opening 27 is arranged to be lower than the lower edge of the water discharging opening 23, so that water seal is favorably established, a communicating vessel is formed, and the deodorization function is realized. A better sealing can be achieved by providing the plug 5 with a lip seal 53 which opens outwards. In the embodiment, the gear 71 is matched with the rack 72, the rotation and the reverse rotation of the overflow cover 6 and the gear 71 are converted into reciprocating linear motion, then the rotor 73 is driven to rotate through the brake cable 75, the valve rod 53 is controlled to lift, and the switching on and off of the water collecting port 22 is realized. In the present embodiment, the first and second limiting surfaces for limiting the movement of the rack 72 are provided, so that the rack 72 can only reciprocate, and the rotation direction of the overflow cover 6 from the first position to the second position is limited to be opposite to the rotation direction from the second position to the first position.

The description of the above specification and examples is intended to be illustrative of the scope of the present application and is not intended to be limiting.
