Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen and bathroom equipment, and particularly relates to a deodorizing sewer device. BACKGROUND

[0002] The bottom of a sink, such as a washbasin or a vegetable washing basin, is usually connected to a sewer pipe to drain the accumulated water in the sink. However, odors, insects and ants in the sewer can easily enter the sink from the sewer, thereby affecting the environmental health near the sink.

[0003] At present, a sewer with a deodorizing function is disclosed in Chinese Patent No. CN209066553U. The sewer comprises a body, a filter basket is embedded in the body, a drain pipe is detachably connected to the lower end of the body, a deodorizing structure is detachably connected to the connection between the body and the drain pipe, the deodorizing structure is located below the filter basket, and a cover is detachably connected to the opening of the body. The invention also discloses a sink, which comprises a sink body, a washing basin is formed by concave recessing the sink body, and the body is embedded in the sink bottom of the washing basin.

[0004] The above-mentioned scheme blocks the backflow of water and the upward floating of odors through the deodorizing structure, thereby realizing deodorization and ensuring the environmental health near the sink. When the cover seals the opening of the body, the washing basin can normally accumulate water. After the cover is removed from the opening of the body, the washing basin is connected to the drain pipe, and the accumulated water in the washing basin can be drained through the drain pipe. After the opening of the body is sealed by the cover, the air pressure in the sealed space between the deodorizing structure and the cover remains unchanged. When the cover is removed, the volume of the sealed space is instantaneously increased, so that the air pressure inside the cover is instantaneously lower than the air pressure outside the cover, and it is relatively laborious to remove the cover. In addition, when the ambient temperature increases, negative pressure is easily generated in the sealed space, that is, negative pressure is formed in the sealed space compared with the external environment, which finally leads to the difficulty of manually removing the cover or the laboriousness of removing the cover, and is not convenient for users to use. SUMMARY

[0005] In view of the deficiencies in the prior art, the present application aims to provide a deodorizing sewer device, which solves the technical problem of how to conveniently remove the water sealing cover under negative pressure.

[0006] The technical problem of the present application is solved by the following technical scheme: A deodorizing sewer device, comprising a body, a water sealing cover, a deodorizing mechanism and a gas pressure balancing mechanism, the body is connected with a sink, a sewer channel is arranged in the body and communicates with the sink, the sewer channel has a water inlet and a water outlet, the water sealing cover is detachably connected with the water inlet and can seal the water inlet, the deodorizing mechanism is arranged in the sewer channel, when the deodorizing mechanism is closed, the deodorizing mechanism divides the sewer channel into an inner cavity one and an inner cavity two, when the water in the inner cavity one opens the deodorizing mechanism, the inner cavity one communicates with the inner cavity two, the gas pressure balancing mechanism is arranged on the body and can communicate the inner cavity one with the outside.

[0007] Through the above technical scheme, when the sink does not need to store water, the water sealing cover is taken out, so that the sink communicates with the water inlet of the sewer channel, the water in the sink enters the inner cavity one through the water inlet, when the weight of the water in the inner cavity one is enough, the water opens the deodorizing mechanism, at this time, the inner cavity one communicates with the inner cavity two, and the water can be smoothly discharged from the sewer channel; after the water sealing cover seals the water inlet, the water inlet of the sewer channel is separated from the inside of the sink, and the sink can normally store water; if the external gas pressure rises, the gas pressure balancing mechanism always keeps the gas pressure value of the inner cavity one close to or equal to the gas pressure value of the outside environment, avoiding that the water sealing cover is difficult to be taken out under the influence of the pressure difference, and facilitating the user to use.

[0008] Preferably, a compensation gas channel is arranged outside the body and communicates with the inner cavity one, the gas pressure balancing mechanism is connected with the compensation gas channel, and the gas pressure balancing mechanism can balance the gas pressure in the inner cavity one with the external gas pressure.

[0009] Through the above technical scheme, the gas pressure balancing mechanism balances the gas pressure in the inner cavity one with the external gas pressure through the compensation gas channel, thereby avoiding that the water sealing cover is affected by the pressure difference between both sides of itself; and after the inner cavity two is sealed by the deodorizing mechanism, the gas in the inner cavity two cannot enter the room through the compensation gas channel, and the deodorizing effect is better.

[0010] Preferably, the gas pressure balancing mechanism comprises a one-way valve, the one-way valve comprises a support, a piston and a pre-tightening piece, the support is arranged in the compensation gas channel, the support has a connecting gas channel which communicates with the compensation gas channel, and a limiting portion is arranged on the side of the connecting gas channel away from the body; the inner end of the piston is provided with a sliding rod, the sliding rod is slidingly connected with the support, the pre-tightening piece is arranged in the connecting gas channel and applies a pre-tightening force to the piston, so that the piston abuts against the limiting portion and seals the connecting gas channel.

[0011] By the above technical scheme, when the external air pressure is close to the air pressure value in the inner cavity one, the one-way valve is in the closed state under the action of the pre-tightening member; if the air pressure in the inner cavity one is less than the external air pressure, the high pressure from the outside will open the piston, so that the inner cavity one, the compensation air channel and the outside are communicated, and the pre-tightening member is compressed by the piston, at this time, the one-way valve is in the open state, until the air pressure in the inner cavity one is close to the external air pressure, the pre-tightening force exerted by the pre-tightening member on the piston will push the piston to slide, so that the piston is re-tightened to the limiting portion, thereby blocking the connecting air channel, at this time, the one-way valve is in the closed state, and the water sealing cover can be easily opened; moreover, the accumulated water in the inner cavity one cannot open the one-way valve, and the waterproof and deodorization effects are better.

[0012] Preferably, a water overflow hole is arranged in the water tank, and the air pressure balancing mechanism comprises a water overflow pipe, one end of the water overflow pipe is connected with the water overflow hole, and the other end of the water overflow pipe is connected with the compensation air channel.

[0013] By the above technical scheme, the water overflow pipe always communicates the water overflow hole and the compensation air channel, so that the difference between the air pressure value in the inner cavity one and the air pressure value in the water tank is minimized, so as to facilitate the normal taking of the water sealing cover. At the same time, when the accumulated water height in the water tank is higher than the height of the water overflow hole, the water flow can directly enter the lower water flow channel from the water overflow hole, avoiding the overflow of the accumulated water from the tank opening of the water tank.

[0014] Preferably, the deodorization mechanism comprises a guide seat, a flow guide sleeve, a blocking cover and a reset member, the guide seat is arranged in the lower water flow channel, the guide seat has a guide hole thereon, the flow guide sleeve is detachably connected in the lower water flow channel and located above the guide seat, the lower end of the blocking cover is provided with a guide pipe, the guide pipe is slidingly connected in the guide hole, the guide pipe and the guide hole have a gas passage groove therebetween, and the reset member can drive the blocking cover to abut against the flow guide sleeve.

[0015] By the above technical scheme, the reset member exerts an upward force on the blocking cover, forcing the blocking cover to abut against the flow guide sleeve, that is, the blocking cover and the flow guide sleeve cooperate to separate the lower water flow channel into independent inner cavities one and two, at this time, the deodorization mechanism is in the closed state; when the weight of the accumulated water in the inner cavity one is enough to overcome the force of the reset member, the blocking cover moves downward and separates from the flow guide sleeve, so that the inner cavities one and two are communicated, at this time, the deodorization mechanism is in the open state, and the accumulated water can pass through the flow guide sleeve and be normally discharged from the inner cavity two; since the deodorization mechanism can only be opened in one direction, the deodorization and anti-backflow effects are better, and the setting of the gas passage groove can effectively avoid the adhesion of the guide pipe and the guide hole, ensuring that the blocking cover is always movable.

[0016] Preferably, the inner ring of the flow guide sleeve is provided with flow guide ribs, and the upper end of the sealing cover is circumferentially distributed with several protrusions. The flow guide groove formed between two adjacent flow guide ribs can guide the flow direction of the water flow, so that the accumulated water can impact the protrusions and force the sealing cover to rotate.

[0017] Through the above technical solution, the guide ribs guide the water in the inner cavity and add kinetic energy to the water, so that the water can impact the protrusion on the sealing cover, thereby causing the sealing cover to rotate while moving downward, thus accelerating the drainage efficiency of the water in the inner cavity.

[0018] Preferably, the reset component includes a magnetic rod and a magnetic ring. The magnetic rod is disposed inside the guide tube, and the magnetic ring is disposed inside the guide seat. The force generated between the magnetic ring and the magnetic rod can drive the sealing cap to move toward the flow guide sleeve.

[0019] Through the above technical solution, the force generated between the magnetic ring and the magnetic rod causes the sealing cover to slide upward and press against the guide sleeve, thereby sealing the lower end of the guide sleeve with the sealing cover, that is, closing the odor prevention mechanism; when the combined force of the water above the sealing cover and the weight of the sealing cover itself is greater than this force, the sealing cover slides downward and away from the guide sleeve, realizing the opening of the odor prevention mechanism. The opening and closing of the sealing cover is convenient.

[0020] Preferably, the drainage device further includes a drain pipe and a sealing mechanism. One end of the drain pipe is connected to the main body, and the other end of the drain pipe is connected to the sealing mechanism. The interior of the drain pipe is in communication with the inner cavity. The sealing mechanism connects the drain pipe to the drainage pipe and can seal the gap between the drain pipe and the drainage pipe.

[0021] Through the above technical solution, the drain pipe connects the main body to the sewer pipe, and the water accumulated in the inner cavity can enter the sewer pipe through the drain pipe. The sealing mechanism seals the gap between the drain pipe and the sewer pipe, ensuring the airtightness between the sewer pipe and the drain pipe, and preventing the odor in the sewer pipe from overflowing into the room.

[0022] Preferably, the sealing mechanism includes a connecting pipe, a first deformable component, an upper locking sleeve, a second deformable component, and a lower locking sleeve. The upper end of the connecting pipe is connected to the drain pipe, and the lower end of the connecting pipe is inserted into the drain pipe, thus connecting the drain pipe to the drain pipe. The first deformable component is disposed at the upper end of the connecting pipe, and the drain pipe can be inserted into the first deformable component. The upper locking sleeve is connected to the upper end of the connecting pipe and can press the first deformable component against the outer wall of the drain pipe. The second deformable component is disposed at the lower end of the connecting pipe, and the lower locking sleeve is connected to the lower end of the connecting pipe, thus pressing the second deformable component against the inner wall of the drain pipe.

[0023] By the above technical scheme, the upper locking sleeve presses the first deformation piece against the outer wall of the drain pipe, realizing the sealing of the gap between the connecting pipe and the drain pipe, the lower locking sleeve and the second deformation piece are inserted into the sewer pipe along with the connecting pipe, the first deformation piece is pressed against the inner wall of the sewer pipe through the lower locking sleeve, realizing the sealing of the gap between the connecting pipe and the sewer pipe, thereby ensuring the air tightness between the drain pipe and the sewer pipe.

[0024] Preferably, a limiting groove one is formed in the inner wall of the pipe opening at the upper end of the connecting pipe, the slot opening of the limiting groove one has a guide surface one, the first deformation piece is arranged in the limiting groove one, and the outer wall of the first deformation piece abuts against the guide surface one, the upper locking sleeve can press the first deformation piece in the limiting groove one and make the first deformation piece shrink along the guide surface one, the lower end of the lower locking sleeve is provided with a guide surface two, the lower end of the connecting pipe has a limiting groove two for accommodating the second deformation piece, the second deformation piece is provided with a guide surface three, the guide surface three abuts against the guide surface two, and the lower locking sleeve can press the second deformation piece in the limiting groove two and make the second deformation piece expand along the guide surface two.

[0025] By the above technical scheme, the upper locking sleeve presses the first deformation piece in the limiting groove one and makes the first deformation piece shrink along the guide surface one, so that the first deformation piece is pressed against the outer wall of the drain pipe, and the lower locking sleeve presses the second deformation piece in the limiting groove two, so that the second deformation piece expands along the guide surface two and abuts against the inner wall of the sewer pipe.

[0026] In summary, the beneficial effects of the present application compared with the prior art are:

[0027] 1. When the external air pressure changes, the air pressure balancing mechanism always keeps the air pressure value of the inner cavity one close to or equal to the air pressure value of the outside, avoiding the difficulty of taking out the water sealing cover under the influence of air pressure difference;

[0028] 2. The structure of the compensation air channel is reasonable, which can balance the air pressure of the inner cavity one and the outside, and also will not cause the back overflow of the odor in the inner cavity two;

[0029] 3. The odor prevention mechanism can only be opened in one direction, and the odor prevention and back overflow prevention effects are better;

[0030] 4. The gap between the drain pipe and the sewer pipe is sealed by the sealing mechanism, which can effectively improve the air tightness between the drain pipe and the sewer pipe and improve the user's experience. BRIEF DESCRIPTION OF DRAWINGS

Figures 1 to 13 The present application has the advantages that the odor-proof mechanism 300 is arranged in the floor drain channel 110 and divides the floor drain channel 110 into the inner cavity one 113 and the inner cavity two 114 when the odor-proof mechanism 300 is closed. The water in the inner cavity one 113 communicates with the inner cavity two 114 when the odor-proof mechanism 300 is opened. The air pressure balancing mechanism 400 is arranged on the body 100 and can communicate the inner cavity one 113 with the outside.

[0057] The bottom of the sink 1 is provided with a through hole 11, and a connecting ring 12 is arranged in the through hole 11.

[0068] As another solution, a limiting pipe 660 can be detachably connected to the lower end of the connecting pipe 610, and the limiting groove two 612 is arranged on the outer wall of the limiting pipe 660, so as to facilitate the installation or disassembly of the deforming member two 640. Alternatively, as shown in Figure 10 、 Figure 12 、 Figure 13 shown, the limiting pipe 660 is replaced by a floor drain core 670 to further improve the deodorization effect; the outer side of the connecting pipe 610 can be connected with a three-way joint 613 or a multi-way joint, and the three-way joint 613 or the multi-way joint is used to connect the drain pipes of other water equipment, so as to improve the utilization rate of the sewer pipe 2.

[0069] Working principle:

[0070] When the sink 1 does not need to store water, the water sealing cover 200 is removed so that the sink 1 is communicated with the water inlet 111 of the sewage flow channel 110, and the water in the sink 1 enters the inner cavity I 113 through the water inlet 111. When the weight of the accumulated water in the inner cavity I 113 is enough, the accumulated water will press the blocking cover 330 downward, so that the central hole 321 communicates the inner cavity I 113 and the inner cavity II 114, and the accumulated water can be smoothly discharged into the sewage pipeline 2 from the inner cavity II 114, the water outlet 112, the drain pipe 500 and the connecting pipe 610. The accumulated water in the inner cavity I 113 is guided by the flow guide rib 322, so that the accumulated water rotates and impacts the protrusion 332 in the inclined direction, and the blocking cover 330 rotates along the flow direction of the accumulated water. The accumulated water above the blocking cover 330 is accelerated to be discharged under the centrifugal effect of the blocking cover 330. After the accumulated water is discharged, the repulsive force between the magnetic ring 342 and the magnetic rod 341 is greater than the gravity of the blocking cover 330, the blocking cover 330 moves upward and resets, so that the blocking cover 330 is tightly reset below the flow guide sleeve 320, and the inner cavity I 113 and the inner cavity II 114 are disconnected by the flow guide sleeve 320 and the blocking cover 330, so that the deodorization and anti-back-overflow purposes of the deodorization mechanism 300 are achieved.

[0071] When the water inlet 111 is sealed by the water sealing cover 200, the water inlet 111 is disconnected with the inside of the sink 1, and the sink 1 can normally store water. When the air pressure outside is close to the air pressure value in the inner cavity I 113, the one-way valve 410 is in a closed state under the action of the pre-tightening member 413. If the air pressure in the inner cavity I 113 is less than the air pressure outside, the high pressure outside will open the piston 412, so that the inner cavity I 113, the compensation air channel 120 and the outside are communicated, and the pre-tightening member 413 is compressed by the piston 412. At this time, the one-way valve 410 is in an open state, and when the air pressure in the inner cavity I 113 is close to the air pressure outside, the force of the air pressure outside on the outside of the piston 412 disappears, and the pre-tightening force of the pre-tightening member 413 on the piston 412 will push the piston 412 to slide, so that the piston 412 is tightly reset to the limiting portion 4112, thereby blocking the connecting air channel 4111. At this time, the one-way valve 410 is in a closed state, and the water sealing cover 200 can be easily opened. Moreover, the accumulated water in the inner cavity I 113 cannot open the one-way valve 410, and the waterproof and deodorization effects are better. That is to say, if the air pressure outside rises, the air pressure balancing mechanism 400 will always keep the air pressure value in the inner cavity I 113 close to or equal to the air pressure value outside, so as to avoid that the water sealing cover 200 is difficult to be removed under the influence of the air pressure difference.

[0072] Embodiment two:

[0073] The difference between embodiment two and embodiment one is that Figure 2 , Figure 5 , Figure 12 , Figure 14As shown, the side wall of the water tank 1 is provided with an overflow hole 13. The air pressure balancing mechanism 400 is preferably an overflow pipe 420. One end of the overflow pipe 420 is connected to the overflow hole 13, and the other end of the overflow pipe 420 is connected to the compensating air passage 120. The overflow pipe 420 connects the overflow hole 13 and the compensating air passage 120, so that the difference between the air pressure value in the inner cavity 113 and the air pressure value in the water tank 1 is minimized, so that the water seal 200 can be removed normally. When the water level in the water tank 1 is higher than the overflow hole 13, the water in the water tank 1 can directly enter the drain channel 110 from the overflow hole 13 and the overflow pipe 420, preventing water from overflowing from the opening of the water tank 1.

[0074] Example 3:

[0075] The difference between Example 3 and Example 2 is as follows: Figure 12 , Figure 15 As shown, the one-way valve 410 and the overflow pipe 420 are used as the air pressure balancing mechanism 400. That is, the one-way valve 410 is set in the compensation air passage 120, one end of the overflow pipe 420 is connected to the outside of the compensation air passage 120, and the other end of the overflow pipe 420 is connected to the overflow hole 13.
