Description

Exhaust deodorization closestool

Technical Field

The utility model belongs to the technical field of cleaners and polishes, concretely relates to novel closestool with exhaust deodorization function.

Background

Toilets such as toilets and urinals are common sanitary appliances in daily life, and can be mainly classified into siphons and direct discharge toilets. The existing closestool is easy to generate odor in the using process, so that an exhaust fan is often needed to exhaust the odor or supplement the odor into fresh air; however, in some toilets, the toilet is not adjacent to the outside due to the building structure, and the exhaust fan cannot be directly installed. In other cases, it may be chosen to solve this problem by providing an air freshener with a fragrance or deodorizing function, but this only masks the odor to a certain extent and does not solve the problem fundamentally.

The discharge duct is ready for the toilet in question and has a sufficient flow capacity to allow it to be used as a discharge line, there being some patents in the prior art with similar concepts.

However, the related toilet, air suction structure and air exhaust mode are not satisfactory, and many products are left in the original and are not commercially available.

Detailed Description

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention. Conventional alternatives and substitutions made by those skilled in the art in light of the teachings of the present disclosure should be considered as within the scope of the present disclosure.

As shown in fig. 1 to 5, a toilet bowl having a deodorizing function for exhausting air includes a bowl liner 100, a siphon tube 110, an air suction mechanism 200, and an air exhausting mechanism 300; the driving assembly 310 is used for driving the gas flow, and an axial flow fan may be used. The bottom of the urinal liner 100 is provided with a liner drainage port for discharging excrement out of the liner, the upper end of the siphon tube 110 is connected with the liner drainage port, and the siphon tube is in an inverted S shape; the siphon tube 110 forms two U-bends (elbows), the former U-bend forming a trap and the latter U-bend forming a siphon trap.

The air suction mechanism 200 includes an upper cover 210 and a middle plate 220, the upper cover 210 and the middle plate 220 are arranged at intervals to form an air suction cavity therebetween, the upper cover 210 and the middle plate 220 are respectively provided with a first mouth portion 2021 and a second mouth portion 2022 which are matched with the upper mouth of the urinal inner container 100, and the first mouth portion 2021 and the second mouth portion 2022 are matched to form a mouth portion 202 of the air suction mechanism 200; the suction mechanism 200 further includes a suction port 203, and the suction port 203 is provided at the mouth portion 202.

The exhaust mechanism 300 comprises a driving assembly 310 and an air duct 320, one end of the air duct 320 is communicated to the air suction cavity, the other end is communicated to the rear end of the siphon tube 110, and the driving assembly 310 is arranged on the air duct 320; meanwhile, a check valve is further disposed in the air duct 320.

In terms of material, the upper cover 210, the urinal inner container 100, the siphon tube 110 and the middle plate 220 may be made of plastic, melamine, etc.; to ensure a consistent feel with existing toilets, some components may also be made of the same ceramic, such as the urinal bladder 100.

As shown in fig. 7, the siphon 110 is divided into a front end and a rear end by taking the siphon bend as a boundary, and the air duct 320 is provided with a one-way valve, so that the normal siphon action of the siphon is not adversely affected; when the liquid level in the urinal inner container 100 is higher than the siphon bend, the siphon tube can generate siphon action to discharge the dirt in the urinal inner container 100 completely. Therefore, to avoid adversely affecting the air path 320, the air path 320 may be communicated to the rear end of the siphon tube 110.

Preferably, to prevent the siphon effect from being affected by the insufficient sealing of the one-way valve, the connection between the air channel 320 and the siphon tube 110 is located below the lowest point of the siphon tube, so as to completely avoid the negative effect on the siphon efficiency (based on the siphon effect being the vacuum formed by the water flowing to the top of the siphon bend and dropping to the lowest point of the water trap); at the same time, the adverse effects of the excreta on the air duct 320 can also be avoided.

In some embodiments, the upper rim portion 202 of the upper cover 210 is formed with a first air-absorbing member 2031 extending downward; a second air suction member 2032 is formed on the middle plate 220 along the edge of the opening 202, and the first air suction member 2031 and the second air suction member 2032 cooperate to form the air suction opening 203.

In other embodiments, as shown in fig. 6, the rear end of the air duct 320 is connected to the siphon tube 110 at a higher position at the rear end thereof, while ensuring the sealing effect of the check valve.

In other embodiments, the toilet further comprises a sensing mechanism 400, which may be a pressure sensing device, disposed at the lower front side of the middle plate 220; since the upper cover 210 and the middle plate 220 are fixedly connected to form a whole, when a user sits on the upper cover 210, the sensing mechanism 400 generates a pressure sensing signal, so that the driving assembly 310 can be turned on to start the exhaust and deodorization functions.
