Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware, in particular to a pull-up drain with a hair filtering function. Background Art

[0002] Drains are widely used in kitchens and bathrooms to open and close basins and bathtubs to store or drain water. For example, when a basin drain is storing or draining water, you need to reach to the bottom of the basin to operate it. When the water in the basin is dirty or draining water in winter, the drainage operation will be very inconvenient.

[0003] When washing and gargling in front of a wash basin, more or less hair often falls down, which blocks the drainage channel after entering the drain and prevents timely drainage. To prevent hair from entering the drain, existing drains are generally equipped with a filter, such as a pull-up drain disclosed in patent announcement No. CN215563062U, in which a partition is provided on the drain plug, and filter holes are evenly distributed on the partition. By providing the partition and the filter holes, the sundries in the water flowing through the drain can be effectively filtered to prevent the sundries from clogging the guide part. However, after long-term use, the hair can easily clog the filter, and the hair needs to be cleaned off before drainage can be smooth. In daily use, the user needs to reach into the dirty water to clean it. Utility Model Content

[0020] It should be noted that the concepts such as "first" and "second" mentioned in the present invention are only used to distinguish between devices, modules or units, and are not used to limit these devices, modules or units to be different devices, modules or units, nor are they used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0021] Please combine Figures 1 to 4 , a pull-type drain with a hair filtering function is shown, comprising a drain pipe 10, a drain plug 20 and a pull-wire device 30, wherein the upper end of the drain pipe 10 is provided with a drain port 101, the drain plug 20 is used to close or open the drain port 101, and the pull-wire device 30 drives the drain plug 20 to move upward away from the drain port 101 in the open state;

[0022] Specifically, a hair collecting piece 40 is arranged below the drain plug 20, and the hair collecting piece 40 is threadedly connected to the drain plug 20 through an external thread at the upper end; a drainage cavity 102 is formed between the hair collecting piece 40 and the inner wall surface of the drain pipe 10, wherein two groups of hair collecting frames are arranged on the outer wall surface of the hair collecting piece 40, and the hair collecting frames are composed of a plurality of hair hooks 401 distributed along the periphery of the hair collecting piece 40, and the upper and lower hair hooks 401 are staggered. It should be understood that the hair collecting piece 40 is provided with a hair collecting hook 401, and the hair collecting hook 401 is provided with a hair collecting hook 401. The water first enters the drain pipe 10 through the drain port 101 opened by the drain plug 20, and then the water flows through the gap of the hair winding hook 401 and falls. Most of the hair is entangled by the hair winding hook 401 or slides down to the hair winding hook 401 and gathers under the combined effect of gravity and water flow. Because most of the hair is gathered and entangled, the hair entangled and gathered can gather to a certain extent and can also form a net to capture the subsequent hair that falls in, so the interception effect is better, and the hair collecting member 40 can be used for a long time without cleaning.

[0023] Specifically, a plurality of guide plates 402 are distributed along the axis at the lower end of the hair collecting member 40, and the tops of the plurality of guide plates 402 form a claw-shaped structure, and a small amount of hair that is not intercepted by the two groups of hair collecting frames is collected by the tops of the guide plates 402, thereby achieving three safeguards to prevent hair from entering the sewer;

[0024] Specifically, the hair collecting piece 40 is threadedly connected to the drain plug 20 via an external thread at the upper end. For subsequent cleaning, it is only necessary to take out the drain plug 20 together with the hair collecting piece 40, which is very convenient.

[0025] Specifically, the wire-lifting device 30 is linked in a non-rigid connection manner to prevent the drain plug 20 from having a vacant position that affects the water storage performance of the drain. The wire-lifting device 30 includes a mounting seat 301, a top rod 302, a pushing member 303, and a wire-pushing driving mechanism 304. The mounting seat 301 is arranged in the drain pipe 10, and the top rod 302 is arranged in the mounting seat 301 along a vertical movement. The upper end of the top rod 302 abuts against the hair collecting member 40, and the pushing member 303 is arranged in the mounting seat 301 through horizontal movement. A pushing portion with an inclined structure is provided on the surface, and the pushing portion abuts against the lower end of the push rod 302. It should be understood that the pushing member 303 moves horizontally in the mounting seat 301 under the drive of the push-wire driving mechanism 304, and pushes the push rod 302 to move upward through its inclined end surface during the movement. The push rod 302 then pushes the hair collecting member 40 to move and pushes the drain plug 20 out of the drain outlet 101, so that the drain outlet 101 is opened for drainage. After the hair collecting member 40 is set, it will not affect the normal operation of the pulling-wire device 30.

[0026] In this embodiment, the push-wire drive mechanism 304 includes a driving wire, a wire sleeve covering the driving wire, and a driving component for driving the driving wire to move in the wire sleeve, wherein one end of the wire sleeve is fixed on the side wall of the corresponding mounting seat 301 of the sewer pipe 10, and the driving component includes a push rod and a pressing head. The push rod part is inserted into the wire sleeve and can move axially relative to the wire sleeve, and is connected to the driving wire. One end of the push rod away from the driving wire extends out of the wire sleeve and is connected to the pressing head.

[0027] Specifically, the wire-lifting device 30 also includes a bellows 305 and a connecting cover 306. The upper end of the bellows 305 covers the upper end of the top rod 302, and the lower end of the bellows 305 is connected to the connecting cover 306. The connecting cover 306 is connected to the mounting seat 301. The bellows 305 and the connecting cover 306 serve as a seal for the mounting seat 301 to prevent dirty water from entering the mounting seat 301 and corroding the top rod 302 and the pushing member 303, thereby ensuring the stability of the wire-lifting device 30.

[0028] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
