The utility model relates to a water discharger, comprising a first water sealing member 100 and a water discharge head 200 .

As shown in Fig. 1, Fig. 2 and Fig. 3, the first water sealing member 100 includes a cup body 110, a water inlet pipe 120, an overflow pipe 130 and a water outlet pipe 140. The cup body 110, the water inlet pipe 120, the overflow pipe 130 and the water outlet pipe 140 can be integrated on the first water sealing member 100 and formed as one piece, or they can be assembled as independent components to form the first water sealing member 100. The following is an example of the cup body 110, the water inlet pipe 120, the overflow pipe 130 and the water outlet pipe 140 being formed as one piece on the first water sealing member 100. The interior of the cup body 110 is hollow to define a water sealing cavity 111. The water inlet pipe 120 is formed at the top of the cup body 110. The water inlet pipe 120 is vertically arranged relative to the water sealing chamber 111. The upper part of the water inlet pipe 120 extends upward and is located outside the water sealing chamber 111. The upper part of the water inlet pipe 120 can be a vertical tube or a curved tube, and the lower part of the water inlet pipe 120 extends vertically downward to the lower part of the water sealing chamber 111. The water inlet pipe 120 is connected with the water sealing chamber 111 through its lower end. The lower part of the water inlet pipe 120 can extend downward along the side wall of the water sealing chamber 111, and the water sealing chamber 111 is half surrounded by the water inlet pipe 120; or there is a certain gap between the lower peripheral wall of the water inlet pipe 120 and the inner wall of the water sealing chamber 111, and the water sealing chamber 111 surrounds the water inlet pipe 120. The water outlet pipe 140 extends outward laterally from the upper side wall of the water cup. The lateral direction of the water outlet pipe 140 can be horizontal, or with a downward tilt. The overflow pipe 130 extends out from the side wall of the water inlet pipe 120. One end of the overflow pipe 130 is communicated with the upper part of the water inlet pipe 120. The lower water head 200 is installed at the upper end of the water inlet pipe 120. In actual use, the lower water head 200 is installed at the sewage outlet at the bottom of the wash basin 600, and a detachable filter screen can be installed inside the lower water head 200 to filter debris. The first water sealing member 100 is connected to the lower water head 200 through the upper end of the water inlet pipe 120. The overflow pipe 130 is connected to the overflow outlet at the upper part of the wash basin 600 through an external water pipe. One end of the water outlet pipe 140 away from the water sealing chamber 111 can be connected to the sewage pipe through an external water pipe. The waste water of the wash basin 600 flows into the water inlet pipe 120 through the lower water head 200, and the waste water flows into the water sealing chamber 111 through the water inlet pipe 120. Wastewater gradually spreads upward in the water sealing chamber 111 until the wastewater is higher than the outlet pipe 140, and the wastewater is discharged from the water sealing chamber 111 from the outlet pipe 140. The water level of part of the water in the water sealing chamber 111 is higher than the lower end of the water inlet pipe 120 and lower than the end of the outlet pipe 140 at the water cup. This part of water is used as water sealing water to realize the water sealing function between the water inlet pipe 120 and the outlet pipe 140. The cup body 110, the water inlet pipe 120, the overflow pipe 130 and the outlet pipe 140 are highly integrated on the first water sealing member 100, and the overall structure is simple, easy to assemble, and small in space. In particular, it can be installed and used in small spaces such as bay windows in the vertical direction. The relative position of the water inlet pipe 120 and the water sealing chamber can fully meet the water seal water level height requirements and wastewater discharge speed requirements.

In some embodiments of the utility model, as shown in FIG. 3 and FIG. 4 , the bottom of the water sealing chamber 111 is an opening, and a bottom cover 300 is installed at the bottom opening of the cup body 110. The bottom cover 300 is used to block the opening of the cup body 110. The lower end of the water inlet pipe 120 is located in the water sealing chamber 111 and close to the inner wall of the bottom cover 300. There is a water gap 301 between the lower end of the water inlet pipe 120 and the cover body, and the water gap 301 is connected to the water sealing chamber 111. The lower end of the water inlet end can be higher than or flush with the bottom opening of the cup body 110. When the water inlet pipe 120 or the water sealing chamber 111 is blocked by foreign matter, the bottom cover 300 can be opened to clear it.

Among them, as shown in Figures 2 and 3, one embodiment of the bottom cover 300 is that the bottom cover 300 includes a connecting portion 310 and a water flow portion 320. The connecting portion 310 and the water flow portion 320 are distributed up and down. A water flow cavity 330 is defined between the connecting portion 310 and the water flow portion 320. The bottom of the cup body 110 is inserted into the water flow cavity 330 and connected to the connecting portion 310, and the two can be connected by threads. When the connecting portion 310 is connected to the cup body 110, the water flow cavity 330 at the corresponding position of the water flow portion 320 is connected to the water sealing cavity 111, and the bottom of the water flow portion 320 is the bottom wall of the bottom cover 300. The bottom of the water flow portion 320 and the lower end of the water inlet pipe 120 constitute the above-mentioned water flow interval 301. In the bottom cover 300 of this structure, the lower end of the water inlet pipe 120 can be set to be flush with the lower end opening of the cup body 110. The water passage cavity 330 of the bottom cover 300 is utilized to increase the water sealing depth of the water sealing cavity 111 , thereby meeting the requirements of different water sealing depth dimensions.

The outer contour of the water cup is not limited to a shape, and its top can be set to a flat top, a pointed top, etc. As shown in Figures 1 and 2, in some embodiments of the present invention, the top of the cup body 110 is a slope 112. The water inlet pipe 120 is formed at the low position of the slope 112, and the water inlet pipe 120 extends vertically. The slope 112 has a certain inclination angle with the axial direction of the water inlet pipe 120. The overflow pipe 130 extends out from the side wall of the water inlet pipe 120 along the inclined direction of the slope 112. Part of the pipe wall of the overflow pipe 130 is formed at the top of the cup body 110, which increases the structural strength of the connection position between the overflow pipe 130 and the water inlet pipe 120. The orientation of the overflow pipe 130 can facilitate the connection of an external water pipe and the connection of the external water pipe to the overflow outlet direction of the wash basin 600 after the connection.

In some embodiments of the utility model, the drain further includes a second water sealing member 700. The second water sealing member 700 includes a cup body 110, a water inlet pipe 120 and a water outlet pipe 140, and the cup body 110, the water inlet pipe 120 and the water outlet pipe 140 on the second water sealing member 700 play the same function as the cup body 110, the water inlet pipe 120 and the water outlet pipe 140 on the first water sealing member 100. The overflow pipe 130 may not be provided on the second water sealing member 700. The water outlet pipe 140 of the first water sealing member 100 and the water outlet pipe 140 of the second water sealing member 700 are connected by a connecting pipe 500. A water outlet 510 is provided on the connecting pipe 500, and the connecting pipe 500 can be set as a T-shaped pipe structure. The water outlet pipe 140 is set to extend horizontally from the side wall of the cup body 110. The two water outlet pipes 140 are opposite, and the two water outlet pipes 140 are respectively connected to the two ends of the connecting pipe 500. The first water sealing member 100 and the second water sealing member 700 discharge waste water into the connecting pipe 500 through the corresponding water outlet pipe 140, and then discharge it to the outside through the water outlet 510. The water outlet 510 is connected to the sewage pipe. In actual use, the first water sealing member 100 and the second water sealing member 700 are respectively connected to two wash basins 600 through different downpipes 200 for use.

Among them, the lower water head 200 and the water inlet pipe 120 can be directly connected through the first locking nut 410. Alternatively, an adapter 400 is provided between the lower water head 200 and the water inlet pipe 120. The adapter 400 is set as a hollow tube structure, one end of the adapter 400 is connected to the lower water head 200 through the second locking nut 420, and the other end of the adapter 400 is connected to the water inlet pipe 120 through the third locking nut 430. As shown in Figure 5, the lower water head 200 corresponding to the first water sealing member 100 is inserted downward into the water inlet pipe 120, and then locked and fixed by the first locking nut 410. An adapter 400 is provided between the water inlet pipe 120 corresponding to the second water sealing member 700 and the lower water head 200. The adapter 400 can be set to a circular tube shape, with stepped positions with increased outer diameters at the upper and lower ends. The upper end of the adapter 400 is connected to the lower water head 200 through the second locking nut 420, and the second locking nut 420 abuts against the stepped position of the upper end of the adapter 400 and is threadedly connected to the lower water head 200; the lower end of the adapter 400 is connected to the upper end of the water inlet pipe 120 through the third locking nut 430 and is threadedly connected to the upper end of the water inlet pipe 120, and the third locking nut 430 abuts against the stepped position of the lower end of the adapter 400. The relative installation distance between the lower water head 200 and the upper end of the water inlet pipe 120 is adjusted through the adapter 400, thereby reducing the design height of the water inlet pipe 120 (as shown in the figure, the height of the water inlet pipe 120 of the second water sealing member 700 is less than the height of the water inlet pipe 120 of the first water sealing member), which is more suitable for adjustment and installation in a smaller installation space.

As shown in Fig. 5 and Fig. 6, the water inlet pipe 120 on the second water sealing member 700 is connected to the lower water head 200 through the adapter 400. A clearance position 710 is provided on the top of the cup body 110 of the second water sealing member 700, and the clearance position 710 sinks downward. The clearance position 710 surrounds the water inlet pipe 120 of the second water sealing member 700. The total height of the water sealing cavity 111 inside the cup body 110 corresponding to the second water sealing member 700 is the same as the total height of the water sealing cavity 111 inside the cup body 110 corresponding to the first water sealing member 100, and the clearance position 710 does not affect the total height of the water sealing cavity 111. The clearance position 710 is used to avoid air and limit the lower stroke position of the third locking nut 430. When the adapter 400 is docked with the water inlet pipe 120, it is fastened by the third locking nut 430, and the third locking nut 430 is located in the clearance position 710. Under the condition of ensuring the total height of the water sealing chamber 111 , the setting of the clearance position 710 can reduce the installation height of the adapter 400 , the third locking nut 430 and the water inlet pipe 120 , and further reduce the height of the second water sealing component 700 .

In some specific embodiments of the utility model, as shown in FIG6 , a partition 520 is provided inside the connecting pipe 500. The partition 520 divides the inside of the connecting pipe 500 into two independent tube cavities 530. The partition 520 can be arranged along the axial direction of the connecting pipe 500, and the two tube cavities 530 are separated along the axial direction of the connecting pipe 500. Or the partition 520 is arranged along the radial direction of the connecting pipe 500, and the two tube cavities 530 are distributed along the axial direction of the connecting pipe 500. The two tube cavities 530 converge at the water outlet 510. One water outlet pipe 140 is connected to one tube cavity 530. After the water in the tube cavity 530 flows to the water outlet 510, it will be directly discharged to the external sewage pipe, and will not flow into another tube cavity 530, thereby avoiding the occurrence of foam backflow between the two wash basins 600 through the drain. At the same time, the first water sealing member 100 and the second water sealing member 700 constitute independent drainage, and the drainage of the two water sealing chambers 111 does not affect each other, thereby ensuring the drainage speed. The connecting pipe 500 is a hard pipe and can meet the hot oil test requirements.

In some embodiments of the utility model, as shown in FIG. 5 and FIG. 6 , the water outlet pipe 140 is coaxially inserted into the connecting pipe 500, and a plurality of sealing rings 150 are sleeved on the end of the water outlet pipe 140. After the water outlet pipe 140 is inserted into the connecting pipe 500, the sealing ring 150 abuts against the inner wall of the connecting pipe 500, thereby ensuring the water tightness of the connection between the water outlet pipe 140 and the connecting pipe 500. A plurality of ribs 141 are provided on the outer wall of the water outlet pipe 140, and the plurality of ribs 141 are distributed along the circumference of the water outlet pipe 140. The ribs 141 can be set to be straight strips or wavy shapes. After the water outlet pipe 140 is inserted into the connecting pipe 500, the ribs 141 abut against the inner wall of the connecting pipe 500. The inner diameter of the connecting pipe 500 is larger than the outer diameter of the water outlet pipe 140, so that the water outlet pipe 140 can be inserted into the connecting pipe 500. The ribs 141 are used to abut against the connecting pipe 500, so as to ensure the coaxiality between the water outlet pipe 140 and the connecting pipe 500, and avoid the water outlet pipe 140 from being deflected relative to the connecting pipe 500 and affecting the water tightness of the connection between the two. The plug-in installation of the water outlet pipe 140 and the connecting pipe 500 allows the water outlet pipe 140 and the connecting pipe 500 to be relatively retractable, and the relative position between the first water sealing member 100 and the second water sealing member 700 can be quickly adjusted according to the relative position of the two wash basins 600 for installation.

The opening position of the water outlet 510 on the connecting pipe 500 may not be limited. In this embodiment, preferably, the water outlet 510 is arranged on the middle side wall of the connecting pipe 500. The water outlet 510 extends radially along the connecting pipe 500. Correspondingly, when the partition 520 is provided, the partition 520 is provided along the connecting pipe 500, and the partition 520 extends axially along the water outlet 510.
