TECHNICAL FIELD

[0001] The present application relates to the field of bathroom equipment, in particular to a toilet cover connection cover type water saving device. BACKGROUND

[0002] General household and hotel use toilet, people in the use of toilet usually according to their own different corresponding press toilet water tank on the full flush button and half flush button, such operation from the surface seems to be according to different needs to flush toilet bowl and small stool, seems to be very in line with the desire to save water, but people use toilet water tank in the drain valve structure determines the half flush button discharge volume is full flush button discharge volume 5 liters of 70% or 3.5 liters, this is mainly because the drain valve structure determines, this is due to the design of the drain valve body height in 20 cm or so, and the sealing element connected to the lifting rod is not more than 15 cm, at the same time, the lifting rod on both sides of the full flush button and half flush button corresponding full flush gear and half flush gear is also usually in 2 cm or so, and the water tank stored water height is usually less than 18 cm, and actually use full flush button when the water tank in the water drop height of 10 cm, full flush gear and half flush gear distance of 2 cm length is the use of full flush button when the water tank in the water consumption height of 10 cm 20%, and the time of the hand in touch half flush button length and water tank itself storage capacity of influence, so that the use of half flush button discharge volume is full flush button discharge volume of five fourths to six fourths, the actual situation is that each use of half flush button water yield is usually greater than full flush button water yield 70%. And in fact, toilet flush toilet water consumption is only about 1 liters, so the structure of the existing toilet drain valve will inevitably lead to great waste of water when flushing the toilet.

[0003] Although the current people on toilet water saving efforts have done a lot, but still not meet the technical requirements of flushing toilet water consumption is flushing stool water consumption of one fifth, so that the existing toilet drain valve structure has always been a problem of flushing toilet water consumption, not only increase the family and hotel water spending, but also not conducive to the whole society water saving. SUMMARY

[0004] The present application aims to overcome the deficiencies in the prior art, provide a simple structure, easy to manufacture, low cost and easy to install toilet cover connection cover type water saving device.

DETAILED DESCRIPTION

[0017] As shown in Figure 1 , Figure 2 and Figure 3 , the toilet sleeve cover type water-saving device of the present application includes a water tank, a large button and a small button, a water inlet valve and a drain valve 1 are arranged in the water tank, the drain valve 1 includes a valve body 2, the valve body 2 includes a water stop assembly, a flushing button and a buoyancy device. The water stop assembly includes a drain cavity, a sealing element and a lifting rod, the sealing element is connected with the lifting rod, and the sealing element is arranged at the lower end of the drain cavity. The flushing button is connected with the lifting rod, and the flushing button includes a full discharge button 3 and a half discharge button 4. The large button and the small button correspond to the full discharge button 3 and the half discharge button 4 through a large button rod and a small button rod respectively.

[0018] As shown in Figure 3As shown, the sleeve cover water-saving device is provided with a fixed sleeve 5, a water distribution cover 6, a portal frame 7 and a return spring 8. The portal frame 7 is in a U shape, and a semicircular top plate 9 is arranged at the top of the portal frame 7. A vertical fixed pressing rod 10 is arranged at the lower end of the middle of the top plate 9. The two sides of the portal frame 7 are provided with sliding rods 11 in a U shape, and support plates 12 are vertically fixed on the outer sides of the sliding rods 11. The fixed sleeve 5 is provided with an open arc-shaped sleeve ring 13 sleeved on the upper end of the valve body 2, and a fixed semicircular pressing plate 14 is arranged in the arc-shaped sleeve ring 13. A pressing plate hole 15 corresponding to the pressing rod 10 is arranged in the middle of the pressing plate 14. Two slides 16 are arranged at the two ends of the outer side of the arc-shaped sleeve ring 13 and relative to the pressing plate 14, and the upper ends of the slides 16 are provided with limiting plates 17 vertical to the slides 16. The water distribution cover 6 is a cylindrical body with two open ends, and is a plastic cover with a smaller upper end opening than a lower end opening and in a horn shape. Support plate holes 18 corresponding to the support plates 12 on the two sliding rods 11 of the portal frame 7 are arranged at the two sides of the upper end of the water distribution cover 6. The diameter of the water distribution cover 6 is 8-10 cm, and the height is 20 cm. The distance between the bottom end of the water distribution cover 6 and the bottom of the water tank after the water distribution cover 6 is fixed to the half-row button 4 is 1 cm. The return spring 8 is sleeved on the pressing rod 10 extending out of the pressing plate hole 15 and between the pressing plate 14 and the top plate 9.

[0019] First, the return spring 8 is sleeved on the pressing rod 10, and then the sliding rods 11 on the portal frame 7 are inserted into the slides 16 of the fixed sleeve 5. At this time, the pressing rod 10 is also inserted into the pressing plate hole 15 on the pressing plate 14, and the return spring 8 is located between the pressing plate 14 and the top plate 9. Then, the support plates 12 on the two sliding rods 11 of the portal frame 7 are inserted into the support plate holes 18 on the water distribution cover 6. Thus, the water distribution cover of the present application is assembled. The upper end of the water distribution cover 6 is limited by the limiting plates 17 of the slides 16 on the fixed sleeve 5, that is, the limiting plates 17 prevent the water distribution cover 6 and the portal frame 7 from moving upward after the return spring 8 rebounds. That is, the limiting plates 17 and the support plates 18 determine the movement distance of the water distribution cover 6 and the portal frame 7 on the drain valve 1 under the cooperation of the return spring 8.

[0020] The assembled water distribution cover 6 is sleeved on the small button rod of the small button on the existing toilet. The lower end of the small button rod is cut off by a length equal to the length of the pressing rod 10. Then, the fixed sleeve 5 on the assembled water distribution cover 6 is sleeved on the upper end of the valve body 2, and the pressing rod 10 is aligned with the half-row button 4 on the drain valve 1. Finally, the water tank cover is closed, and the installation is completed.
