Description

Technical Field

[0001] The invention relates to the field of indoor drainage, and in particular to a float type deodorizing drainage device. Background Art

[0002] In the indoor drainage system, the traditional water-sealed drain pipe has a certain deodorizing effect. However, when the water-sealed drain pipe is not used for a long time, the water seal fails, and the mosquitoes and corrupt odors in the sewer pipes will overflow into the room, which will reduce the quality of people's living environment. At present, there are several types of indoor drainage devices on the market, such as mechanical closed type and magnetic deodorizing type. Although these drainage devices have their own advantages, they also have a problem, that is, the drainage speed is low, it does not meet the national standards, and the deodorizing effect is not ideal. In addition, since the space in the indoor drainage system is often very small, it is very important to optimize the spatial layout of the drain pipe in a small space and enhance its storage performance. Summary of the invention

[0011] The beneficial effects of the present invention are:

[0012] The present invention can be applied to indoor drainage products such as bathroom cabinets, wash basins, and kitchen sinks. When water flows through, the float opens for drainage under the action of water pressure. When no water flows through, in cases where the water in the positive U-shaped tube dries up, sewage flows back, or odor flows back, the float closes under the action of gravity.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and the best embodiments.

[0024] As shown in the figure, the present invention includes a water inlet end, a water outlet end and an odor-proof pipe section arranged between the water inlet end and the water outlet end, the odor-proof pipe section includes a regular U-shaped tube 2 and a float assembly 3, wherein the regular U-shaped tube 2 can store water and prevent odor, the float assembly 3 is arranged on the side of the regular U-shaped tube 2 close to the water outlet end, the float assembly 3 includes a connecting member 34 for connecting the regular U-shaped tube 2 and the water outlet end, a float base 31 arranged in the connecting member 34 and a float 32 hinged above the float base 31, in this example, the connecting member 34 is threadedly connected to the regular U-shaped tube 2 and the water outlet end, a sealing ring 33 is connected between the float base 31 and the inner wall of the connecting member 34, and one side of the float 32 is hinged to one side of the float base 31. The working principle of the present invention is: when the water pressure F=0, the float closes under the action of gravity, and the float sealing gasket on the float can play the role of sealing, odor prevention and water backflow prevention; when the water pressure F>0, the float opens for drainage under the action of the water pressure F; since the float is hollow in this example, when the water pressure F is close to 0, the float can also float to realize the waterway opening and drainage.

[0025] According to the above embodiment, preferably, the bottom surface of the buoy is a curved surface structure, and a sealing gasket is connected between the bottom surface of the buoy and the buoy base 31. This setting can effectively improve the sealing performance of the connection between the buoy and the buoy base 31. When the water in the positive U-shaped pipe 2 is exhausted, sewage flows back, and odor is reversed, the odor-proof pipe section can achieve physical sealing and odor-proofing through the sealing gasket on the buoy assembly 3, thereby playing a dual odor-proofing role.

[0026] According to the above embodiment, preferably, the water inlet end includes a retractable drainage pipe section 1 disposed above one end of the regular U-shaped pipe 2, and the retractable drainage pipe section 1 is connected to one end of the regular U-shaped pipe 2. The horizontally arranged retractable drainage pipe section 1 can greatly enhance the adaptability of the drainage pipe. In this example, the retractable drainage pipe section 1 is a prior art, which can be a corrugated pipe section, and can also be a retractable sleeve. The retractable sleeve includes an inner pipe and an outer pipe that are relatively slidably connected, a dynamic sealing ring 33 is provided between the inner pipe and the outer pipe, and the inner pipe and the outer pipe are connected by a connecting sleeve.

[0027] According to the above embodiment, preferably, the water outlet includes an inverted U-shaped tube 4, one end of which is connected to the positive U-shaped tube 2 through a connector 34. In this example, the inverted U-shaped tube 4 is a corrugated tube, and the setting of the inverted U-shaped tube 4 can produce a siphon effect when the water flows full of the tube, thereby increasing the drainage volume. In addition, since a horizontally arranged drainage pipe section is added to the water inlet end, the inverted U-shaped tube 4 at the water outlet end can be moved backward, thereby effectively increasing the storage space.

[0028] The present invention can be adapted to indoor drainage products such as bathroom cabinets, wash basins, and kitchen sinks. When water flows through, the float opens for drainage under the action of water pressure. When no water flows through, in cases where the water in the positive U-shaped tube 2 is exhausted, sewage flows back, or odor flows back, the float closes under the action of gravity. Through double odor prevention, it can seal and isolate odors and prevent water backflow, and has good application and promotion value.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
