Description

Deodorizing drainage device

Technical Field

The invention relates to the technical field of kitchen and bathroom equipment, and in particular to an anti-odor drain device.

Background technique

The bottoms of sinks such as washbasins and vegetable sinks are usually connected to sewer pipes to drain the accumulated water in the sinks, but the odor, insects and ants in the sewers can easily enter the sinks from the sewers, thus affecting the environmental health near the sinks.

At present, a Chinese patent with the announcement number CN209066553U discloses a drain with an anti-odor function. The drain includes a body, a filter basket is embedded in the body, a drain pipe is detachably connected to the lower end of the body, an anti-odor structure is detachably connected to the connection between the body and the drain pipe, the anti-odor 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 includes a sink body, which is concave to form a washing sink, and the body is embedded in the bottom of the washing sink.

The above scheme prevents water from flowing back and odor from rising through the anti-odor structure, thereby preventing odor and ensuring a healthy environment near the sink; when the lid seals the opening of the main body, water can be stored normally in the sink, and after the lid is removed from the opening of the main body, the sink is connected to the drain pipe, and the accumulated water in the sink can be discharged through the drain pipe; after the lid seals the opening of the main body, since the air pressure in the enclosed space between the anti-odor structure and the lid remains unchanged, when the lid is taken out, it is equivalent to instantly increasing the volume of the enclosed space, so that the air pressure on the inside of the lid will instantly be lower than the air pressure on the outside of the lid, and it is more difficult to take the lid out; in addition, when the external ambient temperature rises, negative pressure is also easily generated in the enclosed space, that is, negative pressure is formed in the sealed space compared to the external environment, which ultimately makes it difficult to manually take out the lid, or it is more laborious to take it out, which is not convenient for users to use.

Summary of the invention

In view of the deficiencies in the prior art, the purpose of the present invention is to provide an odor-proof drainage device, which solves the technical problem of how to conveniently remove the water sealing cover under negative pressure conditions.

The above technical objectives of the present invention are achieved through the following technical solutions: an odor-proof drainage device, the drainage device includes a main body, a water sealing cover, an odor-proof mechanism and an air pressure balance mechanism, the main body is connected to a water sink, a drainage channel connected to the water sink is opened in the main body, the drainage channel has a water inlet and a water outlet, the water sealing cover is detachably connected to the water inlet and can seal the water inlet; the odor-proof mechanism is arranged in the drainage channel, when the odor-proof mechanism is closed, the odor-proof mechanism divides the drainage channel into an inner cavity one and an inner cavity two, when the accumulated water in the inner cavity one opens the odor-proof mechanism, the inner cavity one is connected with the inner cavity two; the air pressure balance mechanism is arranged on the main body, and the air pressure balance mechanism can connect the inner cavity one to the outside world.

Through the above technical solution, when the sink does not need to store water, the water sealing cover is taken out to connect the sink with the water inlet of the sewer channel, and the water in the sink enters the inner cavity one through the water inlet. When the weight of the accumulated water in the inner cavity one is sufficient, the accumulated water will open the anti-odor mechanism. At this time, the inner cavity one is connected with the inner cavity two, and the accumulated 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 store water normally; if the external air pressure rises, the air pressure balance mechanism always keeps the air pressure value of the inner cavity one close to or equal to the air pressure value of the external environment, so as to avoid the water sealing cover being difficult to remove under the influence of the air pressure difference, which is convenient for users to use.

Preferably, a compensating air passage connected to the inner cavity one is opened on the outer side of the main body, the air pressure balancing mechanism is connected to the compensating air passage, and the air pressure balancing mechanism can balance the air pressure in the inner cavity one with the external air pressure.

Through the above technical scheme, the air pressure balancing mechanism balances the air pressure of the inner cavity one with the external air pressure through the compensating air duct, thereby preventing the water sealing cover from being affected by the pressure difference on both sides of itself; and after the inner cavity two is sealed by the anti-odor mechanism, the gas in the inner cavity two cannot enter the room through the compensating air duct, and the anti-odor effect is better.

Preferably, the air pressure balancing mechanism includes a one-way valve, which includes a support, a piston and a pre-tightening member. The support is arranged in the compensating air channel, and the support has a connecting air channel connected to the compensating air channel. A limiting portion is provided on the side of the connecting air channel away from the main body; a sliding rod is provided at the inner end of the piston, and the sliding rod is slidably connected to the support. The pre-tightening member is arranged in the connecting air channel and applies a pre-tightening force to the piston, so that the piston is pressed against the limiting portion and seals the connecting air channel.

Through 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 a closed state under the action of the pre-tightening member; if the air pressure in the inner cavity one is lower than the external air pressure, the external high pressure will open the piston from the outside, so that the inner cavity one and the compensation airway are connected with the outside, and the pre-tightening member is compressed by the piston. At this time, the one-way valve is in an open state until the air pressure in the inner cavity one is close to the external air pressure. The pre-tightening force applied by the pre-tightening member to the piston will push the piston to slide, so that the piston is pressed against the limit part again, thereby blocking the connecting airway. At this time, the one-way valve is in a closed state, and the water sealing cover can be opened relatively easily; moreover, the accumulated water in the inner cavity one cannot open the one-way valve, and the waterproof and deodorizing effects are better.

Preferably, an overflow hole is provided in the water tank, and the air pressure balancing mechanism comprises an overflow pipe, one end of the overflow pipe is connected to the overflow hole, and the other end of the overflow pipe is connected to the compensation air duct.

Through the above technical solution, the overflow pipe always connects the overflow hole and the compensation airway, so that the difference between the air pressure value in the inner cavity 1 and the air pressure value in the water tank is minimized, so that the water sealing cover can be normally taken. At the same time, when the height of the accumulated water in the water tank is higher than the height of the overflow hole, the water flow can directly enter the sewer channel from the overflow hole to prevent the accumulated water from overflowing from the notch of the water tank.

Preferably, the anti-odor mechanism includes a guide seat, a guide sleeve, a sealing cover and a reset member, the guide seat is arranged in the sewer channel, the guide seat is provided with a guide hole, the guide sleeve is detachably connected in the sewer channel and is located above the guide seat, the lower end of the sealing cover is provided with a guide tube, the guide tube is slidably connected in the guide hole, a ventilation groove for gas to pass through is provided between the guide tube and the guide hole, and the reset member can drive the sealing cover to press against the guide sleeve.

Through the above technical solution, the reset member applies an upward force to the blocking cover, forcing the blocking cover to press against the guide sleeve, that is, the blocking cover and the guide sleeve cooperate to separate the sewer flow channel into independent inner chamber one and inner chamber two, and the anti-odor mechanism is in a closed state at this time; when the weight of the accumulated water in inner chamber one is sufficient to overcome the force of the reset member, the blocking cover moves down and separates from the guide sleeve, so that the inner chamber one and the inner chamber two are connected, and the anti-odor mechanism is in an open state at this time, and the accumulated water can pass through the guide sleeve and be discharged normally from the inner chamber two; since the anti-odor mechanism can only be opened in one direction, the anti-odor and anti-overflow effects are better, and the setting of the ventilation groove can effectively avoid the adhesion of the guide tube and the guide hole, ensuring that the blocking cover is always in a movable state.

Preferably, the inner ring of the guide sleeve is provided with guide ribs, and the upper end of the sealing cover is circumferentially distributed with a plurality of protrusions, and the guide grooves formed between two adjacent guide ribs can guide the flow direction of the water flow, so that the accumulated water can impact the protrusions, forcing the sealing cover to rotate.

Through the above technical solution, the guide ribs guide the accumulated water in the inner cavity one and add kinetic energy to the accumulated water, so that the accumulated water can impact the protrusion on the sealing cover, so that the sealing cover rotates while moving downward, thereby accelerating the discharge efficiency of the accumulated water in the inner cavity one.

Preferably, the reset member comprises a magnetic rod and a magnetic ring, the magnetic rod is arranged in the guide tube, and the magnetic ring is arranged in the guide seat, and the force generated between the magnetic ring and the magnetic rod can drive the sealing cover to move toward the guide sleeve.

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, so that the sealing cover seals the lower end of the guide sleeve, that is, the anti-odor mechanism is closed; when the combined force of the accumulated water above the sealing cover and the sealing cover's own gravity is greater than the force, the sealing cover slides downward and away from the guide sleeve, thereby realizing the opening of the anti-odor mechanism, and the sealing cover is easy to open and close.

Preferably, the drainage device also includes a drain pipe and a sealing mechanism, one end of the drain pipe is connected to the main body, the other end of the drain pipe is connected to the sealing mechanism, and the interior of the drain pipe is connected to the second inner cavity; the sealing mechanism connects the drain pipe to the drainage pipe, and the sealing mechanism can seal the gap between the drain pipe and the drainage pipe.

Through the above technical solution, the drain pipe connects the main body with the sewer pipe, and the accumulated water in the inner cavity 2 can enter the sewer pipe through the drain pipe, while the sealing mechanism seals the gap between the drain pipe and the sewer pipe to ensure the air tightness between the sewer pipe and the drain pipe, thereby preventing the odor in the sewer pipe from overflowing into the room.

Preferably, the sealing mechanism includes a connecting pipe, a deformable member 1, an upper locking sleeve, a deformable member 2 and a lower locking sleeve, the upper end of the connecting pipe is connected to the drain pipe, the lower end of the connecting pipe is inserted into the sewer pipe, and the connecting pipe connects the drain pipe to the sewer pipe; the deformable member 1 is arranged at the upper end of the connecting pipe, the drain pipe can be inserted into the deformable member 1, the upper locking sleeve is connected to the upper end of the connecting pipe, and the upper locking sleeve can press the deformable member 1 against the outer wall of the drain pipe; the deformable member 2 is arranged at the lower end of the connecting pipe, the lower locking sleeve is connected to the lower end of the connecting pipe, and the lower locking sleeve can press the deformable member 2 against the inner wall of the sewer pipe.

Through the above technical scheme, the upper locking sleeve presses the deformation member 1 against the outer wall of the drain pipe to achieve the sealing of the gap between the connecting pipe and the drain pipe; the lower locking sleeve and the deformation member 2 are inserted into the sewer pipe along with the connecting pipe, and the deformation member 2 is pressed against the inner wall of the sewer pipe through the lower locking sleeve to achieve 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.

Preferably, a limiting groove 1 is provided on the inner wall of the pipe mouth at the upper end of the connecting tube, and the groove of the limiting groove 1 has a guiding surface 1, the deformable member 1 is arranged in the limiting groove 1, and the outer wall of the deformable member 1 is in contact with the guiding surface 1, and the upper locking sleeve can press the deformable member 1 into the limiting groove 1 and make the deformable member 1 contract along the guiding surface 1; a guiding surface 2 is provided on the lower end of the lower locking sleeve, and the lower end of the connecting tube has a limiting groove 2 for accommodating the deformable member 2, and a guiding surface 3 is provided in the deformable member 2, and the guiding surface 3 is in contact with the guiding surface 2, and the lower locking sleeve can press the deformable member 2 into the limiting groove 2 and make the deformable member 2 expand along the guiding surface 2.

Through the above technical solution, the upper locking sleeve presses the deformation member 1 into the limiting groove 1, and causes the deformation member 1 to contract along the guide surface 1, thereby pressing the deformation member 1 against the outer wall of the drain pipe; the lower locking sleeve presses the deformation member 2 into the limiting groove 2, thereby causing the deformation member 2 to expand along the guide surface 2 and press against the inner wall of the sewer pipe.

Embodiment 1:

A deodorizing drainage device, as shown in Figures 1 to 13, comprises a main body 100, a water sealing cover 200, a deodorizing mechanism 300 and an air pressure balancing mechanism 400. The main body 100 is connected to a water tank 1. A drainage channel 110 connected to the water tank 1 is provided in the main body 100. The drainage channel 110 has a water inlet 111 and a water outlet 112. The water sealing cover 200 is detachably connected to the water inlet 111 and can seal the water inlet 111. The deodorizing mechanism 300 is arranged in the drainage channel 110. When the deodorizing mechanism 300 is closed, the deodorizing mechanism 300 separates the drainage channel 110 into an inner cavity 113 and an inner cavity 2 114. When the accumulated water in the inner cavity 113 opens the deodorizing mechanism 300, the inner cavity 113 is connected to the inner cavity 2 114. The air pressure balancing mechanism 400 is arranged on the main body 100, and the air pressure balancing mechanism 400 can connect the inner cavity 113 to the outside.

A through hole 11 is provided at the bottom of the water tank 1, and a connecting ring 12 is arranged in the through hole 11. The connecting ring 12 is detachably connected to the main body 100, that is, the main body 100 is connected to the water tank 1 through the connecting ring 12, and the water sealing cover 200 is pluggable and connected to the connecting ring 12, and a filter basket 1111 is arranged in the water inlet 111.

A compensation air passage 120 connected to the inner cavity 113 is provided on the outer side of the main body 100. The air pressure balancing mechanism 400 is connected to the compensation air passage 120, and the air pressure balancing mechanism 400 is used to balance the air pressure in the inner cavity 113 with the air pressure of the external environment. In this embodiment, the air pressure balancing mechanism 400 is preferably a one-way valve 410, which includes a support 411, a piston 412 and a pre-tightening member 413. The support 411 is arranged in the compensation air channel 120, and the support 411 has a connecting air channel 4111 connected to the compensation air channel 120, and the connecting air channel 4111 has a limiting portion 4112 on the side away from the main body 100; the inner end of the piston 412 is provided with a sliding rod 4121, and the sliding rod 4121 is slidably connected to the support 411, and the pre-tightening member 413 is arranged in the connecting air channel 4111, and the pre-tightening member 413 applies a pre-tightening force to the piston 412 in the direction of the limiting portion 4112, so that the piston 412 is pressed against the limiting portion 4112 and seals the connecting air channel 4111; the pre-tightening member 413 can be a conventional compression spring, or it can be in the form of a magnet of the following reset member 340.

The deodorizing mechanism 300 includes a guide seat 310, a guide sleeve 320, a plugging cover 330 and a reset member 340. The guide seat 310 is arranged in the sewer flow channel 110. The outer portion of the guide seat 310 is preferably hemispherical to prevent the guide seat 310 from hooking debris. The guide seat 310 has a guide hole 311. The guide sleeve 320 is detachably connected to the sewer flow channel 110 and is located above the guide seat 310. The guide sleeve 320 has a central hole 321 connected to the sewer flow channel 110. The lower end of the plugging cover 330 is provided with a guide pipe 331. The guide pipe 331 is provided with a guide tube 332. The sealing cover 330 is slidably connected in the guide hole 311, so that the sealing cover 330 can slide between the guide seat 310 and the guide sleeve 320. A venting groove 350 for gas to pass through is provided between the guide tube 331 and the guide hole 311. The reset member 340 can drive the sealing cover 330 to press against the guide sleeve 320, that is, the deodorizing mechanism 300 is in a closed state at this time. The guide sleeve 320 and the sealing cover 330 are in contact through the sealing ring 360. The sealing ring 360 can be arranged at the lower end of the guide sleeve 320 or at the upper end surface of the sealing cover 330.

The ventilation groove 350 can be vertically opened on the hole wall of the guide hole 311, or can be opened on the outer wall of the guide tube 331, or the diameter of the guide hole 311 can be increased so that the guide tube 331 can slide freely in the guide hole 311 and will not stick to the inner wall of the guide hole 311, that is, the large-diameter guide hole 311 is used as the ventilation groove 350.

Furthermore, a connecting portion 115 is provided in the sewer channel 110, and the connecting portion 115 is detachably connected to the guide seat 310. An avoidance hole 1151 and a balancing air duct 1152 are provided on the connecting portion 115. The avoidance hole 1151 is connected to the guide hole 311, and the balancing air duct 1152 is connected to the avoidance hole 1151, and the opening of the balancing air duct 1152 faces the water outlet 112, so that the balancing air duct 1152 connects the guide hole 311 to the water outlet 112, ensuring that when the sealing cover 330 moves down and covers the upper end of the guide hole 311, the air pressure value in the guide hole 311 is similar to the air pressure value in the sewer channel 110, thereby preventing the air pressure in the guide hole 311 from being lower than the air pressure in the sewer channel 110, which causes the sealing cover 330 to fail to reset normally, and also preventing the accumulated water in the inner cavity 113 from accidentally entering the balancing air duct 1152.

A guide rib 322 is provided on the hole wall of the center hole 321, and a plurality of protrusions 332 are distributed circumferentially on the upper end of the blocking cover 330. The guide groove 323 formed between two adjacent guide ribs 322 can guide the flow direction of the water flow, so that the accumulated water can impact the protrusion 332, forcing the blocking cover 330 to rotate; as another solution, the protrusion 332 on the blocking cover 330 can also be omitted, and only the guide rib 322 in the guide sleeve 320 is retained.

The reset member 340 is preferably a magnetic rod 341 and a magnetic ring 342. The magnetic rod 341 is arranged in the guide tube 331, and the magnetic ring 342 is arranged in the guide seat 310. The magnetic force between the magnetic ring 342 and the lower end of the magnetic rod 341 is a repulsive force, which applies an upward force to the blocking cover 330, and finally makes the blocking cover 330 close to the guide sleeve 320. In this embodiment, the magnetic rod 341 and the magnetic ring 342 are both permanent magnets. As another solution, the length of the magnetic rod 341 can be appropriately extended so that the magnetic force between the magnetic ring 342 and the lower end of the magnetic rod 341 is an attractive force. As long as the magnetic attraction can provide the blocking cover 330 with a force pointing to the side of the guide sleeve 320, the blocking cover 330 can still be close to the lower end of the guide sleeve 320; or, the reset member 340 can also use a conventional compression spring, as long as the compression spring can apply a force pointing to the direction of the guide sleeve 320 to the blocking cover 330.

The drainage device also includes a drain pipe 500 and a sealing mechanism 600. One end of the drain pipe 500 is snap-fitted or threadedly connected to the main body 100, and the other end of the drain pipe 500 is connected to the sealing mechanism 600, and the interior of the drain pipe 500 is connected to the inner cavity 114; the sealing mechanism 600 connects the drain pipe 500 to the drainage pipe 2, and the sealing mechanism 600 can seal the gap between the drain pipe 500 and the drainage pipe 2.

The sealing mechanism 600 includes a connecting pipe 610, a deformable member 1 620, an upper locking sleeve 630, a deformable member 2 640 and a lower locking sleeve 650. The upper end of the connecting pipe 610 is plugged into the drain pipe 500, and the lower end of the connecting pipe 610 is inserted into the sewer pipe 2. The connecting pipe 610 connects the drain pipe 500 to the sewer pipe 2. The deformable member 1 620 is arranged at the upper end of the connecting pipe 610, and the drain pipe 500 can be inserted into the deformable member 1 620. The outer side of the upper locking sleeve 630 is provided with an anti-slip groove 1 631. The upper locking sleeve 630 is threadedly connected to the upper end of the connecting pipe 610, and the upper locking sleeve 630 can press the deformable member 1 620 against the outer wall of the drain pipe 500; the deformable member 2 640 is arranged at the lower end of the connecting pipe 610, and the outer side of the lower locking sleeve 650 is provided with an anti-slip groove 2 651, the lower locking sleeve 650 is threadedly connected to the lower end of the connecting pipe 610 and the end of the lower locking sleeve 650 is located outside the sewer pipe 2, so that the user can rotate the lower locking sleeve 650 so that the lower locking sleeve 650 can press the deformable member 2 640 against the inner wall of the sewer pipe 2.

It should be noted that, as shown in FIG. 9 , FIG. 12 , and FIG. 14 , the drain pipe 500 may be a single-inlet and single-outlet corrugated pipe, or may be a two-inlet and one-outlet Y-shaped or T-shaped structure.

Furthermore, a limiting groove 611 is provided on the inner wall of the pipe opening at the upper end of the connecting pipe 610, and a guide surface 6111 is provided at the notch of the limiting groove 611.

When the water tank 1 does not need to store water, the water sealing cover 200 is removed, so that the water tank 1 is connected to the water inlet 111 of the sewer flow channel 110, and the water in the water tank 1 enters the inner cavity 113 through the water inlet 111. When the weight of the accumulated water in the inner cavity 113 accumulates to a sufficient amount, the accumulated water will press the sealing cover 330 downward, so that the central hole 321 connects the inner cavity 113 and the inner cavity 2 114, and the accumulated water can be smoothly discharged into the sewer pipe 2 from the inner cavity 2 114, the water outlet 112, the drain pipe 500, and the connecting pipe 610; the accumulated water in the inner cavity 113 is drained by the guide rib 322 The blocking cover 330 is guided to rotate and impact the protrusion 332 along the inclined direction, and the blocking cover 330 rotates with the flow direction of the accumulated water, and the accumulated water above the blocking cover 330 is accelerated to be discharged due to 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, and the blocking cover 330 moves up and resets, so that the blocking cover 330 is pressed tightly against the bottom of the guide sleeve 320 again, and the inner cavity 1 113 and the inner cavity 2 114 are separated by the guide sleeve 320 and the blocking cover 330 again, thereby achieving the purpose of preventing odor and overflow of the deodorizing mechanism 300.

After the water sealing cover 200 seals the water inlet 111, the water inlet 111 is separated from the inside of the water tank 1, and the water tank 1 can store water normally; when the external air pressure is close to the air pressure value in the inner cavity 113, the one-way valve 410 is in a closed state under the action of the preload member 413. If the air pressure in the inner cavity 113 is lower than the external air pressure, the external high pressure will open the piston 412, so that the inner cavity 113 and the compensation airway 120 are connected to the outside, and the preload member 413 is compressed by the piston 412. At this time, the one-way valve 410 is in an open state. When the air pressure in the inner cavity 113 is close to the external air pressure, the external air pressure acts on the outer side of the piston 412. When the force disappears, the pre-tightening force applied by the pre-tightening member 413 to the piston 412 will push the piston 412 to slide, so that the piston 412 is pressed against the limit portion 4112 again, thereby blocking the connecting airway 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 113 cannot open the one-way valve 410, and the waterproof and odor-proof effects are better; that is to say, if the external air pressure rises, the air pressure balancing mechanism 400 will always keep the air pressure value of the inner cavity 113 close to or equal to the external air pressure value, so as to avoid the water-sealing cover 200 being difficult to remove under the influence of the air pressure difference.

Embodiment 2:

The difference between the second embodiment and the first embodiment is that, as shown in FIG. 2 , FIG. 5 , FIG. 12 , and FIG. 14 , the side wall of the water tank 1 is provided with an overflow hole 13 , and the air pressure balance mechanism 400 is preferably an overflow pipe 420 , one end of which is connected to the overflow hole 13 , and the other end of which is connected to the compensation airway 120 . The overflow pipe 420 connects the overflow hole 13 and the compensation airway 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 sealing cover 200 can be taken out normally. When the accumulated water height in the water tank 1 is higher than the overflow hole 13 , the accumulated water in the water tank 1 can directly enter the sewer channel 110 from the overflow hole 13 and the overflow pipe 420 , so as to prevent the accumulated water from overflowing from the notch of the water tank 1 .

Embodiment three:

The difference between the third embodiment and the second embodiment is that, as shown in FIG. 12 and FIG. 15 , the one-way valve 410 and the overflow pipe 420 are used as the air pressure balance mechanism 400 at the same time. That is, the one-way valve 410 is arranged in the compensation air channel 120, one end of the overflow pipe 420 is connected to the outside of the compensation air channel 120, and the other end of the overflow pipe 420 is connected to the overflow hole 13.
