Description

Technical Field

[0001] The invention relates to a drainage device with odor prevention function. Background Art

[0002] The drainage device commonly used in households, when the washbasin is full of water, the water flows from the overflow hole to the drain pipe. Because there is a gap between the sealing gasket and the thread, the water will flow along the drain pipe thread to the ground. There is often water on the ground, which brings a lot of inconvenience. During the installation process, the locking nut must be rotated to fix the drainage device on the washbasin. The number of turns required is very laborious and time-consuming. At the same time, the current drainage device is directly connected from the drain pipe to the hose for direct discharge, which will cause odor to flow back into the room. Summary of the invention

[0016] In order to more clearly illustrate the technical solution of the present invention, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0018] Figure 2 It is a cross-sectional view of the present invention. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Referring to the drawings in the specification, a drainage device with odor prevention function includes a main body 10 sleeved on the outer periphery of a drainage pipe 40, a drainage hose 20 is arranged at the lower end of the main body, a cylinder 30 sleeved on the outer periphery of the lower end of the drainage pipe is arranged in the main body, a first water passage 41 is formed between the inner peripheral wall of the cylinder and the outer peripheral wall of the drainage pipe, a second water passage 42 connected with the first water passage is formed between the inner peripheral wall of the main body and the outer peripheral wall of the cylinder, and a water stop ring 50 for opening and closing the second water passage and water passing through the drainage hose is arranged at the lower end of the cylinder. In the present invention, the first water passage and the second water passage cooperate to form a water seal to form a first odor prevention structure, and after the water in the second water passage is drained away, the water stop ring closes the connection between the second water passage and the drainage hose to form a second odor prevention structure. The two waterproof structures can effectively prevent odors or insects from the drainage hose from going to the drainage pipe.

[0021] Specifically, a connecting ring 11 which is sleeved with a drainage hose is provided at the lower end of the main body, and a water stop ring which matches with the inner circumferential wall of the connecting ring is provided at the lower end of the cylinder. When the water stop ring matches with the inner circumferential wall of the connecting ring, the above-mentioned second deodorizing structure is formed. When water flows from the first water channel to the second water channel, the impact of the water opens the water stop ring. At this time, the water flows from between the water stop ring and the inner circumferential wall of the connecting ring to the drainage hose. In a preferred embodiment, the water stop ring is a bowl-shaped member with its opening facing downward.

[0022] Furthermore, a compression sleeve 60 is provided in the body and is sleeved on the outer periphery of the drain pipe. The outer periphery of the compression sleeve is screwed with the inner periphery of the upper end of the body. A notch 61 is provided on the inner peripheral wall of the lower end of the compression sleeve. A first inclined surface 62 is provided between the upper end of the compression sleeve and the notch. A connecting block 63 is provided on the notch. In one embodiment, at least two connecting blocks are provided which are symmetrical with respect to the axial center line of the drain pipe. These connecting blocks are arranged in an annular manner. A thread 64 matching with the drain pipe is provided on the connecting block. A second inclined surface 65 matching with the first inclined surface is provided on the upper end of the connecting block. An elastic member 66 is provided between the lower end of the connecting block and the body. The elastic member is provided between the cylinder and the connecting block. The elastic member is a spring or an elastic sheet. During the installation process of the present invention, the main body (which already contains other components) is inserted from the lower end of the drain pipe. At this time, the threads on the outer periphery of the drain pipe squeeze the connecting block, and then through the cooperation of the first inclined surface and the second inclined surface, the connecting block moves outward and downward, that is, the connecting block expands outward until it reaches the installation position. At this time, through the cooperation of the elastic member, the first inclined surface and the second inclined surface, the connecting block retracts inward and hugs the drain pipe to complete the installation.

[0023] Furthermore, a connecting piece 67 is provided on the outer periphery of the lower end of the compression sleeve, a card interface 68 is provided on the connecting piece, and a card block 31 matching with the card interface is provided on the outer periphery of the cylinder.

[0024] In a preferred use, the present invention is mainly connected to a wash basin, and a sealing gasket 70 is arranged above the compression sleeve, and the sealing gasket is located at the lower end of the compression sleeve and the wash basin 80, so as to prevent water from flowing to the ground along the drain pipe thread.

[0025] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
