Description

Technical Field

[0001] The present application generally relates to the technical field of bathrooms, and in particular, to a deodorizing pipe structure and a toilet. Background Art

[0002] As people's living standards continue to improve, smart homes and smart bathrooms are also developing and improving in a healthier and smarter direction. Consumers often have higher requirements for the deodorization function of toilets.

[0003] Toilet devices are prone to odor, and the deodorization structure has a significant effect on improving the environment of the bathroom. In order to facilitate the installation and make the overall structure of the toilet device more compact and simple, some toilet devices connect the deodorization pipe with the flushing pipe of the toilet, so that the flushing pipe of the toilet and the deodorization pipe have a common pipe section. When the flushing pipe of the toilet is flushing, the fan in the deodorization pipe is not turned on. After the flushing pipe of the toilet is flushed, the fan is turned on to deodorize the toilet through the deodorization pipe.

[0004] Since the flushing pipe and the deodorizing pipe of the toilet have a common pipe section, especially for the flushing water inlet connected to the flushing pipe on the toilet seat with a hidden water tank, the water in the flushing pipe of the toilet cannot be discharged quickly, and part of the water in the flushing pipe will flow back into the deodorizing pipe, which may flood the deodorizing fan and affect the service life of the fan. In the prior art, a seal is set in the deodorizing pipe to block the water flow to the fan during the flushing process, but some water will still enter the lower half of the deodorizing pipe during the state switching of the seal, so the fan is still flooded from time to time. Utility Model Content

DETAILED DESCRIPTION

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0029] In the related art, a fan can be used to deodorize the toilet. The deodorization structure mainly includes a deodorization pipe structure and a fan. The deodorization pipe structure is connected to the side wall of the flushing pipe. When the flushing pipe is not flushed, the fan can be started to extract the odor from the flushing pipe and the deodorization pipe. When the flushing pipe is flushed, water will flow into the deodorization pipe. When the water flow is large, it is easy to submerge the fan. Therefore, it is necessary to set a movable water flow structure to cut off the water flow when flushing, so as to solve the problem of water submerging the fan.

[0030] See also Figure 1 The embodiment of the present application provides a deodorizing pipe 100 structure, including one end of the deodorizing pipe 100 for communicating with the flushing pipe 200 of the toilet, and the other end of the deodorizing pipe 100 is connected to the outside. The outside refers to the external space, or a relatively open area where odor emission can be achieved. The deodorizing pipe 100 can be directly connected to the outside, or it can be discharged to the outside after passing through a fan 300 or other equipment.

[0031] See also Figures 2 to 4 The deodorizing pipe 100 has a first air-passing hole 17 and a second air-passing hole 18. The second air-passing hole 18 is arranged upstream of the first air-passing hole 17. Odor or water flows through the second air-passing hole 18 and the first air-passing hole 17 in sequence. A one-way plug 13 is arranged at the first air-passing hole 17, and a sealing member 14 is arranged at the second air-passing hole 18. When the pipe 200 is flushed for deodorization, the one-way plug 13 is separated from the sealing cooperation with the first air-passing hole 17, and the sealing member 14 is separated from the sealing cooperation with the second air-passing hole 18, and the gas is discharged to the outside through the first air-passing hole 17 and the second air-passing hole 18.

[0032] When flushing the flushing pipe 200, under the action of external force, the one-way plug 13 blocks the first air hole 17, and the seal 14 blocks the second air hole 18. The external force may be the buoyancy of water, water pressure, driving force of the mechanical structure, gravity, etc. The deodorizing pipe 100 is sealed and blocked during flushing by double-layer sealing. The double-layer sealing can improve the situation where the single-layer sealing does not respond in time or cannot be blocked when a fault occurs, and can better ensure the blocking effect.

[0033] A structure for cooperating with the one-way plug 13 and the seal 14 can be provided in the deodorizing pipe 100, and a first air hole 17 and a second air hole 18 are provided on the structure. The first air hole 17 and the second air hole 18 can be coaxially arranged, wherein the axis is in the vertical direction.

[0034] In this embodiment, a water diversion chamber 20 is formed on one side of the deodorization pipe 100 close to the flushing pipe 200, and the water diversion chamber 20 is connected to the flushing pipe 200. The seal 14 and the one-way plug 13 are both arranged in the water diversion chamber 20, and the whole component can be arranged in the water diversion chamber 20, or part of it can be arranged in the water diversion chamber 20. When the flushing pipe 200 is flushed, the water flows into the water diversion chamber 20, and the one-way plug 13 moves to a position to block the first air through hole 17 under the action of buoyancy and / or water pressure, and the one-way plug 13 blocks the first air through hole 17. The seal 14 swings or slides to a position to block the second air through hole 18 under the action of buoyancy and / or water pressure, and the seal 14 blocks the second air through hole 18. The state switching of the seal 14 and the one-way plug 13 is realized by buoyancy and / or water pressure, which saves the setting of other mechanical structures and can respond in time.

[0035] Specifically, the deodorizing pipe 100 is provided with a flow hole 19 and a windshield groove 15 located on one side of the flow hole 19. The windshield groove 15 is located in the water diversion chamber 20. The windshield groove 15 is used to block the airflow to prevent the seal 14 from swinging or sliding under the action of the airflow. The flushing pipe 200 is connected to the first air through hole 17 and the second air through hole 18 through the flow hole 19. When the flushing pipe 200 is deodorized, the seal 14 moves into the windshield groove 15.

[0036] Preferably, the deodorizing pipe 100 may include a first pipe 11 and a second pipe 12 connected to each other, wherein the first pipe 11 is V-shaped, and the other end of the first pipe 11 is connected to the flushing pipe 200. The second pipe 12 is linear, and the other end of the second pipe 12 is connected to the outside. The V-shaped pipe facilitates the deodorizing pipe 100 to be arranged on the side wall of the flushing pipe 200, and the fan 300 or other deodorizing equipment is usually arranged at a certain height and connected through a linear pipe.

[0037] The wind shield groove 15 is arranged at the corner of the first pipe 11, and an inclined surface 151 is arranged at the corner for arranging the seal 14. The inner wall of the vertical part of the first pipe 11 is provided with a card slot 16, and the seal 14 is provided with a protrusion 141 that cooperates with the card slot 16, and the seal 14 can swing to cooperate with the card slot 16. When there is no flushing, the seal 14 swings downward under the action of its own gravity and is placed in the wind shield groove 15. When flushing, the water flows into the water diversion chamber 20, and the seal 14 swings upward under the action of buoyancy, and finally seals the second air through hole 18. Preferably, the seal 14 can be provided with a buoyancy chamber. Placing the seal 14 through the wind shield groove 15 avoids the seal 14 from moving under the action of airflow, and can move under the action of buoyancy. The design is ingenious and convenient, and it can switch between different states well.

[0038] See also Figures 2 to 3 In some embodiments, the one-way plug 13 adopts a plug-like structure. The one-way plug 13 includes a guide portion 132 and a sealing gasket 131. The sealing gasket 131 is located at the lower end of the guide portion 132. The guide portion 132 passes through the first air through hole 17. Under the guidance of the guide portion 132, the one-way plug 13 slides back and forth along the central axis of the first air through hole 17. When not flushing, there is no water in the water diversion chamber 20. Under the action of the one-way plug 13's own gravity, the one-way plug 13 slides downward, and the one-way plug 13 and the first air through hole 17 are separated from the sealing fit. When flushing, water flows from the second air through hole 18 to between the second air through hole 18 and the first air through hole 17, and the water flow impacts the one-way plug 13. Under the action of a certain buoyancy, the one-way plug 13 slides upward and seals the first air through hole 17. Preferably, an annular mating surface is provided at the first air through hole 17, and the annular mating surface is matched with the annular end surface corresponding to the sealing gasket 131.

[0039] Preferably, the center line of the second air through hole 18 overlaps with the center line of the one-way plug 13, and the diameter of the second air through hole 18 is smaller than the diameter of the sealing part of the one-way plug 13. After the water flows in from the second air through hole 18, it can impact the one-way plug 13 more concentratedly, so that the one-way plug 13 moves to a sealed state at a faster speed.

[0040] See also Figures 4 to 5 In other embodiments, the one-way plug 13 is a sphere, and the first air-passing hole 17 is conical. The one-way plug 13 in the sphere cooperates with the conical first air-passing hole 17. Under the dual effects of water flow impact and buoyancy, the two can show a trend of becoming more and more plugged. After the impact force subsides, the sealing relationship between the two can also be well maintained only under the effect of buoyancy. Avoid water overflow directly from the first air-passing hole 17 and the second air-passing hole 18.

[0041] In other embodiments, a control switch may be provided to control the state switching of the sealing member 14 and the one-way plug 13. The control switch includes a mechanical switch or an electric control switch.

[0042] In other embodiments, a fan module 300 is further included, and the fan module 300 is disposed on the deodorizing duct 100. When the fan module 300 is started, the one-way plug 13 and the first air through hole 17 are separated from the sealing fit, and the sealing member 14 and the second air through hole 18 are separated from the sealing fit.

[0043] In some embodiments, the toilet includes a water tank, a toilet seat and a flushing pipe 200, the flushing pipe 200 is respectively connected to the water tank and the toilet seat, and also includes the above-mentioned deodorizing pipe 100 structure, the deodorizing pipe 100 structure is connected to the side wall of the flushing pipe 200. When deodorizing, that is, when not flushing, the odor generated in the toilet seat can be discharged to the outside through the flushing pipe 200 and the deodorizing pipe 100, and the gas can be discharged with the help of a fan 300 or other equipment.

[0044] The invention also includes a water tank, in which a drain valve is provided, and the drain valve is opened to supply water to the flushing pipe through the water tank. Alternatively, the invention also includes a water pump connected to the water tank, and water is pumped to the flushing pipe through the water pump. Alternatively, the invention also includes a solenoid valve, and water is supplied to the flushing pipe through the solenoid valve.
