Description

Technical Field

[0001] The utility model belongs to the technical field of drainage, and in particular relates to a drainage device for a shower room. Background Art

[0002] When the shower room is in use, human hair and some tiny debris are often washed down and enter the drainage device. These hair and some tiny debris can easily cause blockage of the drainage device and affect normal use.

[0003] When existing drainage devices are clogged, it is often necessary to disassemble the device components one by one, and the disassembly steps are very cumbersome.

[0004] Since the drainage device is connected to the underground water pipe, bad smells may rise into the shower room. Existing anti-odor technologies are basically divided into water-sealed and self-sealed types. Among them, the self-sealed type uses magnets for self-sealing, but as some iron slag in the water flow is adsorbed near the magnet, the magnetic force decays, thus affecting the normal use of the drainage device, which is very inconvenient. Utility Model Content

[0005] The purpose of the utility model is to solve the problems described in the above background technology that the current drainage device for shower room is easy to be blocked and the magnet of the magnetic self-sealing device is easy to fail. A new drainage device for shower room is proposed, which can clear blockage without disassembly and the magnetic force of the magnet is not easy to diminish.

[0011] Furthermore, an opening is provided above the connection between the inner shell and the outer shell.

[0012] In the above technical solution, the opening is used to discharge water entering from the driving gear.

[0013] Furthermore, the outer side wall of the inner shell is also connected to a protective plate, the protective plate is located below the filter unit (3), and the protective plate is located above the drainage unit.

[0014] In the above technical solution, the protective plate is used to prevent the magnet from contacting water and prolong the effective time of the magnet's magnetic force.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only embodiments of a part of the present invention rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0031] A drainage device for a shower room comprises a housing 1, a cover 2, a filter unit 3 and a drainage unit 4.

[0032] The housing 1 comprises an inner housing 101, an outer housing 102 and a closure member 103. The outer housing 102 is sleeved on the outside of the inner housing 101. The upper ends of the inner housing 101 and the outer housing 102 are respectively connected to the closure member 103. The lower end of the outer housing 102 is bent inwardly and connected to the inner housing 101, forming a cavity inside. An opening 5 is provided on the wall of the inner housing 101 of the cavity, and the opening 5 is used to discharge water flowing in from the driving gear 305.

[0033] The cover body 2 is mounted on the closing member 103 , and a plurality of drainage holes 201 are defined on the cover body 2 .

[0034] The filter unit 3 includes two support members 301, a connecting rod 302, two filter plates 303, a passive gear 304 and a driving gear 305. The two support members 301 are symmetrically arranged and connected to the inner wall of the outer shell 102. The connecting rod 302 penetrates the inner shell 101 to connect the two support members 301. The connecting rod 302 can rotate freely. A sealing ring 8 is provided at the place where the connecting rod 302 penetrates the inner shell 101 to enhance the sealing performance of the place and prevent water from overflowing. The passive gear 304 is provided between the inner shell 101 and the outer shell. 102, a passive gear 304 is fixed on the connecting rod 302, the passive gear 304 is meshed with the active gear 305, the active gear 305 passes through the closing piece 103, the center of the active gear 305 is rotatably connected to the housing 102, and two filter plates 303 are symmetrically arranged on both sides of the circumference of the connecting rod 302, the two filter plates 303 are semicircular, and filter holes 306 are provided on the two filter plates 303, and the aperture of the filter hole 306 is smaller than the drainage hole 201.

[0035] The drainage unit 4 includes two symmetrically arranged water retaining plates 401, two extension plates 402 and four magnets 403. The two water retaining plates 401 are semicircular and extend long extension portions outward. The long extension portions penetrate the inner shell 101. The water retaining plates 401 are rotatably connected to the inner shell 101. In this embodiment, a hinged manner is adopted. A magnet 403 is fixed below the long extension portion. An extension plate 402 is provided below the magnet 403. The extension plate 402 is connected to the outer wall of the inner shell 101. A magnet 403 is fixed above the extension plate 402. The magnet 403 fixed above the extension plate 402 is attracted to the magnet 403 fixed below the long extension portion.

[0036] A protective plate 6 is provided on the outer wall of the inner shell 101 . The protective plate 6 is tilted downward to guide the flow of water and prevent the water from contacting the magnet 403 . The protective plate 6 is located above the long strip extension and below the passive gear 304 .

[0037] A waterproof shell 7 is provided outside the driving gear 305. Normally, the waterproof shell 7 is in a closed state to prevent water from flowing from the driving gear 305 into the interior of the shower room drainage device. When it is necessary to clear the blockage of the filter plate 303, the waterproof shell 7 can be removed and the driving gear 305 can be rotated.

[0038] A limit block is connected to the driving gear 305 above the cover 2 to limit the rotation angle of the driving gear 305, so that the rotation angle of the driving gear 305 from one side of the upper surface of the closure member 103 to the other side of the limit block just makes the connecting rod 302 rotate 180 degrees.

[0039] The working principle of the utility model is as follows: when the filter plate 303 is blocked, it is only necessary to rotate the active gear 305, the active gear 305 drives the passive gear 304 to rotate, the passive gear 304 drives the connecting rod 302 to rotate, the connecting rod 302 drives the filter plate 303 to rotate, at this time, the filter plate 303 is rotated 180 degrees, the obstruction comes to the bottom of the filter plate 303, and then the filter plate is impacted by water flow, the water's own gravity and the impact force of the water flow can flush the obstruction out of the filter hole 306 of the filter plate, thereby solving the blockage problem.

[0040] When the shower room is not in use, the two water baffles 401 of the drainage unit 4 are in a closed state due to the attraction between the magnet 403 fixed above the extension plate 402 and the magnet fixed below the water baffle 401. When in use, water flows to the drainage unit 4, and due to the gravity of the water itself, the water baffle 401 is pressed down, and the two water baffles 401 are opened, and the water can directly flush into the sewer pipe for drainage.

[0041] During the above use process, the water flow will not contact the magnet 403, and the iron slag in the water flow will not be absorbed by the magnet 403, so that the magnetic force of the magnet 403 will not be weakened, thereby extending the service life of the product.

[0042] Finally, it should be noted that this embodiment is only used to illustrate the present invention and does not limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
