The specific structure of the overflow seat 1 is shown in fig. 26. As shown in FIG. 26, the bubbler 12 is disposed at the water outlet 1122 and is connected to the water outlet cavity by screw threads, so that the outlet water can obtain more varied spray effects. The valve core hole cover 13 is arranged at the valve core hole 113, the gear hole cover 15 is arranged at the gear hole 114, the processing hole cover 14 is arranged at the processing hole 115 (not shown in fig. 26), the connecting piece 16 is connected with the seat body 11 through a screw and is arranged at the edge of the overflow port 1111, a connecting hole is formed in the connecting piece, and an internal thread is formed in the connecting hole; the sealing washer 17 is covered on the connecting piece 16 and the seat body 11 at the edge of the overflow port 1111; the end cover 18 and the sealing washer 17 clamp the side wall 201 of the bathtub body therebetween, the end cover 18 is provided with a connecting sleeve extending into a connecting hole, and the connecting sleeve is provided with an external thread screwed with the internal thread of the connecting hole, so that the overflow base 1 is fixedly connected to the side wall 201 of the bathtub body.

The shape and structure of the overflow cover 2 are shown in fig. 8 to 11. As shown in fig. 8 to 11, the overflow cover 2 is provided with a rotating shaft 22 for rotatably connecting with the overflow base 1, and an overflow cover handle 21 is further provided on the outer portion thereof near the peripheral edge. The axis of the hinge 22 is shown as being parallel to the axis of the weir 1111 (parallel to each other means, of course, not coincident with each other). In the present embodiment, the axis of the rotation shaft 22 is located above and to the left of the axis of the weirs 1111. Fig. 8, 9 and 10 show the state of the overflow cover 2 with respect to the overflow base 1 when rotated to the first position, the second position and the third position, respectively. As can be seen, the second position is between the first position and the third position. In this embodiment, the overflow cover 2 is reciprocally rotated between the first position, the second position and the third position in sequence with respect to the overflow base 1. As shown in fig. 8, when the overflow cover 2 is rotated to the first position, the overflow cover 2 shields and closes the overflow ports 1111; as shown in fig. 9 and 10, when the overflow cover 2 is rotated to the second position and the third position, the overflow cover 2 does not shield the overflow 1111 and the water outlet 1122, so that the overflow 1111 and the water outlet 1122 are opened. The overflow cover handle 21 allows a user to easily manipulate the overflow cover 2 to rotate about the rotation shaft 22 with respect to the overflow base 1.

The shape of the on-off valve 3 is shown in fig. 12. As shown in fig. 12, the switch valve 3 is a rotary switch valve provided with a rotary driving end 313. The other end of the switch valve 3 is provided with a switch valve water inlet 311, and the side wall of the switch valve 3 is provided with a switch valve water outlet 312. As shown in fig. 26, the switch valve 3 is disposed in the water inlet channel 112 of the seat body 11 of the overflow seat 1, and specifically, it is installed in the valve core cavity through the valve core hole 113, so that the switch valve water inlet end 311 is communicated with the water inlet 1121, and the switch valve water outlet end 312 is communicated with the water outlet 1122. The rotary drive end 313 of the on-off valve 3 projects into the gear chamber. Thus, the water inlet passage 112 is opened and closed by driving the rotary driving end 313 of the open/close valve 3.

Fig. 1 shows the shape of the water discharge valve 4, and fig. 14 to 16 show the structure of the water discharge valve 4. As shown, the drain valve 4 includes a valve housing 41, a plug 42, and a rotor 43. As shown in fig. 13, the valve housing 41 is provided with a water receiving opening 411, a water collecting opening 412, and a water discharge opening 413 which communicate with each other. Wherein, the water receiving opening 411 and the water outlet 413 are respectively arranged at two sides of the valve casing 41, the water collecting opening 412 is arranged at the bottom wall 202 of the bathtub body and is arranged at the upper end of the valve casing 41, the water receiving opening 411 is used for communicating with the water outlet 1112 of the overflow seat 1, and the water outlet 413 is used for communicating with a sewer pipeline. The valve housing 41 is provided with a rotor bore 414, the axis of the rotor bore 414 being perpendicular to the axis of the water collection opening 412 and also perpendicular to the axis of the water collection opening 411 and the axis of the water discharge opening 413. As shown in fig. 14 to 16, the valve housing 41 is further provided with a partition 415, the partition 415 extending downward from the top of the valve housing 41 and forming a drainage opening 416 with the bottom wall of the valve housing 41. The drain opening 416 communicates the water receiving opening 411 and the water collecting opening 412 to the drain opening 413. The upper edge of the water passing opening 416 is lower than the lower edge of the water outlet 413, so that water seal can be established in the valve shell 41 to form a communicating vessel, and the deodorization function of the drain valve 4 is realized. The structure of the plug 42 is shown in fig. 14-16. As shown in the figure, the plug 42 is provided with a plug body 421 and a valve rod 422 extending downward from the plug body 421, and a sealing ring 423 is further provided at the periphery of the plug body 421, wherein the sealing ring 423 is a lip-shaped sealing ring and opens outward. As shown in fig. 14 to 16, the plug 42 slides in a vertical direction (i.e., an axial direction of the water collection opening 412) with respect to the valve housing 41 to open or close the water collection opening 412. The rotor 43 is provided with a rotor rotation shaft 431 and a pick 432 as shown in fig. 14 to 16. Wherein the rotor rotation shaft 431 is inserted into the rotor hole 414 of the valve housing 41 and rotates about the axis of the rotor hole 414 relative to the valve housing 41. Of course, the rotation axis of the rotor shaft 431 is perpendicular to the axis of the water collecting opening 412 and also perpendicular to the sliding direction of the plug 42. The pick 432 is disposed radially on the rotor shaft 431, is disposed below the valve stem 422, and drives the plug 42 to slide upward by pushing the valve stem 422 upward. Fig. 14, 15 and 16 show the state of the discharge valve 4 when the overflow cover 2 is in the first position, the second position and the third position, respectively. As shown in fig. 14, when the overflow cover 2 is rotated to the first position, the rotor 43 rotates until the shifting piece 432 pushes up against the valve rod 422, so that the plug 42 slides upwards to be away from the water collecting opening 412, thereby opening the water collecting opening 412, and the water in the bathtub body 200 can be discharged from the water collecting opening 412 through the water passing opening 416 and the water outlet 413. As shown in fig. 15, when the overflow cover 2 is rotated to the second position, the rotor 43 rotates until the shifting piece 432 still contacts the valve rod 422, but the plug 42 slides downward to close the water collecting port 412 due to its own weight. As shown in fig. 16, when the overflow cover 2 is rotated to the third position, the rotor 43 is rotated until the shifting piece 432 is away from the valve rod 422, and the plug 42 naturally blocks the water collecting opening 412 by its own weight. Thereby, interlocking between the opening and closing of the weir 1111 and the opening and closing of the drain valve 4 is formed, that is, when the overflow cover 2 is rotated to the first position to close the weir 1111, the drain valve 4 opens the water collection port 412, and when the overflow cover 2 is rotated to the second position and the third position to open the weir 1111, the drain valve 4 closes the water collection port 412. In this embodiment, the plug 42 uses a lip-shaped sealing ring with an outward opening to seal the water collecting opening 412, so as to achieve a better sealing effect.

As shown in fig. 1, the overflow pipe 5 has one end connected to the water outlet end (i.e., the drain port 1112) of the overflow passage 111 and the other end connected to the water receiving port 411 of the drain valve 4, so that the water in the overflow port 1111 is guided to the drain valve 4 and is discharged to the drain port 413 through the drain port 416.

The drain pipe 6 is, as shown in fig. 1, a bellows pipe, one end of which is connected to the drain port 413 of the drain valve 4, and the other end of which is inserted into a municipal sewer pipe or a sewer pipe in a house.

The transmission member 7 includes a partial gear mechanism 71, a rack and pinion mechanism 72, and a pulling mechanism 73, as shown in fig. 17 to 25. As shown in the drawing, the incomplete gear mechanism 71 includes a sector gear 711 coaxially rotation-stopped connected to the overflow cover 2 and a first gear 712 coaxially rotation-stopped connected to the rotation driving end 313 of the on-off valve 3. As shown in fig. 17 and 18, when the overflow cover 2 is rotated to the first position, the non-toothed portion of the sector gear 711 faces the first gear 712, and the sector gear 711 is disengaged from the first gear 712. As shown in fig. 20 and 21, when the overflow cover 2 is rotated to the second position, the toothed portion of the sector gear 711 just starts to mesh with the first gear 712. As shown in fig. 23 and 24, when the overflow cover 2 is rotated to the third position, the toothed portion of the sector gear 711 is still in a meshed state with the first gear 712. It can be seen that when the overflow cover 2 is rotated between the first position and the second position, the sector gear 711 is disengaged from the first gear 712, and the rotation of the sector gear 711 cannot rotate the first gear 712, so that if the on-off valve 3 is set in the closed state when the overflow cover 2 is in the first position, it is inevitable that the on-off valve 3 is also in the closed state when the overflow cover 2 is in the second position. When the overflow cover 2 is rotated between the second position and the third position, the sector gear 711 is engaged with the first gear 712, and therefore, the rotation of the sector gear 711 inevitably rotates the first gear 712, so that the on-off valve 3 is switched from the closed state to the open state by the rotation of the overflow cover 2. Therefore, the incomplete gear mechanism in the embodiment can well realize the three-position double-control function of bathtub water overflowing and bathtub water inlet. In the present embodiment, both the sector gear 711 and the first gear 712 are located in the gear cavity of the housing 11. As shown in the figure, the rack and pinion mechanism 72 includes a second gear 721 coaxially connected to the overflow cover 2 in a rotation-stopping manner and a rack 722 engaged with the second gear 721. In this embodiment, the second gear 721 is integrally connected to the sector gear 711 and is distributed along the axial direction of the rotation shaft 22 of the overflow cover 2, and a part of the tooth surface of the second gear 721 is smoothly continuous with the tooth surface of the sector gear 711. The second gear 721 is also located in the gear cavity of the seat body 11 of the overflow seat 1, and the rack 722 is located in the rack cavity 116 of the seat body 11. It should be noted that, in this embodiment, when the overflow cover 2 rotates to the first position, the rack 722 is located at the highest position and abuts against the first limiting surface 1161 of the rack cavity 116. When the overflow cover 2 rotates to the third position, the rack 722 is at the lowest position and abuts against the second limiting surface of the rack cavity 116. Therefore, since the rack 722 can only move between the first limiting surface 1161 and the second limiting surface, the rotation limitation of the second gear 721 engaged therewith is realized, and the rotation limitation of the overflow cover 2 coaxially connected with the second gear 721 in a rotation-stop manner is also realized, that is, the overflow cover 2 can only rotate between the first position and the third position, and must rotate back and forth to be reset. As shown, the pulling mechanism 73 includes a wire sleeve 731, a pull rod 732, and a brake wire 733. Wherein, one end of the wire sheath 731 is fixed relative to the overflow base 1, and the other end is fixed relative to the valve housing 41. The pull rod 732 is fixed to the rotor shaft 431 of the rotor 43 and extends radially from the rotor shaft 431, but in this embodiment, the extending direction of the pull rod 732 forms a certain angle with the extending direction of the pull tab 432, and the angle is set such that the pull tab 432 is raised when the pull rod 732 rotates backward and the pull tab 432 is lowered when the pull rod 732 rotates forward. The brake wire 733 is connected at one end to a lower end of the rack 722 and at the other end to a free end of the pull rod 732. Fig. 19, 22 and 25 show the state of the pulling mechanism 73 and the state of the plug 42 when the overflow cover 2 is in the first position, the second position and the third position, respectively. As shown in fig. 19, when the overflow cover 2 is at the first position, the rack 722 is at the highest position, and the brake cable 733 pulls the pull rod 732 to the last position, so that the shifting piece 432 drives the plug 42 to move to the highest position. As shown in fig. 22, when the overflow cover 2 is in the second position, the rack 722 is in the middle, the brake cable 733 pulls the pull rod 732 to the middle position, so that the shifting piece 432 is also lowered to the middle position, and at this time, the plug 42 just abuts against the shifting piece 432 and also blocks the water collecting opening 412. As shown in fig. 25, when the overflow cover 2 is in the third position, the rack 722 is in the lowest position, the brake wire 733 pushes the pull rod 732 to the most forward position, so that the pull tab 432 is also lowered to the lowest position, at which time the pull tab 432 is disengaged from the plug 42, and the plug 42 is seated at the water collection port 412 and blocks the water collection port 412.

Fig. 26 shows the water inflow direction Y when the overflow cover 2 is in the third position. At this time, the switch valve 3 is driven by the first gear 712 to be in an open state, the rack 722 is driven by the second gear 721 to be in a lowest state, and water flow is introduced from the water inlet 1121, passes through the valve core cavity to the switch valve 3, flows upwards into the water outlet cavity, and flows out of the bubbler 12. Since the overflow cover 2 does not cover the water outlet 1122 from the outside of the bubbler 12, the flow rate of the water supplied into the bathtub can be large. Of course, if overflow occurs during the water supply, overflow may flow from the overflow 1111, which has been opened by the overflow cover 2, to the drain 1112 through the overflow passage 111, to the drain 6 through the overflow pipe 5 and the drain valve 4, and finally to the sewer pipe.

As will be appreciated from the foregoing description, the bathtub drainer 100 of the present embodiment achieves the objectives of controlling bathtub water intake and bathtub water overflow in one operational manner by rotating the overflow cover 2 to different positions relative to the overflow base 1. Since the axis of the rotation shaft 22 of the overflow cover 2 is parallel to the axis of the overflow 1111, when the overflow cover 2 is rotated until the overflow 1111 is opened and the water outlet 1122 is opened, the overflow cover 2 does not shield the overflow 1111 any more, so that the flow rate of the bathtub overflow and the bathtub intake water is greatly increased. This application adopts overflow lid 2 to realize the operation by 1 off-axis pivoted modes of relative overflow seat, and the operation mode is novel, occupies smallly, simple structure. The bathtub drainer 100 in this embodiment further controls the opening and closing of the drain valve 4 by the rotation of the overflow cover 2 relative to the overflow base 1, and enables the opening and closing of the overflow port 1111 to interlock with the opening and closing of the drain valve 4, that is, the drain valve 4 is closed when the overflow port 1111 is opened, and the drain valve 4 is opened when the overflow port 1111 is closed, so that a user can easily observe whether the drain valve 4 is correctly opened. This is because, generally, when bathing is completed, it is not normally possible to observe whether the drain valve 4 is opened or not due to bubbles in the bath tub. And in this application, can judge whether drain valve 4 opens through observing the change of the relative gap 1111 position of overflow lid 2, therefore user experience is better. The bathtub drainer 100 in this embodiment realizes a three-position double control mechanism by providing the incomplete gear mechanism 71. Specifically, the overflow cover 2 is rotated among three positions, the overflow 1111 is closed in the first position, the overflow 1111 is opened in the second and third positions, and the on-off valve 3 is closed when the overflow cover 2 is in the first and second positions and opened when the overflow cover 2 is in the third position. If a complete gear mechanism is used, the closing stroke of the on-off valve 3 is caused to be larger than the opening stroke, so that a special on-off valve needs to be designed, thereby increasing the cost. The present application, by means of the incomplete gear mechanism 71, can realize the above-mentioned three-position double control mechanism by using the ordinary on-off valve 3. The bathtub drainer 100 in this embodiment realizes forced reciprocating rotation of the overflow cover 2 by the rack-and-pinion mechanism 72 and the limit of the rack chamber 116 to the stroke of the rack 722. This accords with user's use habit, lets the user carry out the control to overflow, intake and drainage through new operation mode more easily. In the drain valve 4 of this embodiment, the partition 415 is provided, and the upper edge of the water passing opening 416 is set lower than the lower edge of the water discharging opening 413, so that a water seal is established in the drain valve 4 to form a communicating vessel, thereby achieving a deodorization function.

The bathtub 1000 in this embodiment is shown in fig. 27, and includes the bathtub drainer 100, the bathtub body 200, the shower head 300, the mixing valve, and the temperature adjustment handle 400 in this embodiment. Wherein the bathtub drain 100 is as described above. The tub body 200 is also provided with tub body side walls 201, a tub body bottom wall 202 and a tub body top wall (where the shower 300 and the temperature adjustment knob 400 are installed in the figure), as is conventionally known. The overflow seat 1 of the bathtub drainer 100 is fixedly connected to the sidewall 201 of the bathtub body, and the overflow port 1111 is opened on the inner surface of the sidewall 201 of the bathtub body. The valve casing 41 of the drain valve 4 is fixedly connected with the bottom wall 202 of the bathtub body, and the water collecting opening 412 is provided with the upper edge of the bottom wall 202 of the bathtub body. The shower head 300 of the present embodiment is installed on the top wall of the bathtub body to provide another water injection manner for the bathtub 1000 therethrough. The water mixing valve is provided with two water inlet ends and two water outlet ends and is used for mixing cold water and hot water and adjusting the water temperature of mixed water by adjusting the mixing proportion. The two water inlet ends of the water mixing valve are respectively connected with a cold water source and a hot water source, and the two water outlet ends are respectively connected with a water inlet 1121 of the bathtub dehydrator 100 and a water inlet end of the shower head 300. The temperature adjusting handle 400 is arranged on the top wall of the bathtub body and connected with the driving end of the water mixing valve for driving the water mixing valve to change the mixing proportion of cold water and hot water.

The bathtub 1000 in the application can completely need no extra water inlet control mode, reduces the bathtub water inlet control handle and reduces the cost.

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.
