The water inlet side of the reversing pipeline 7 is communicated with external water supply and is provided with a plurality of water outlet sides, and each water outlet side is respectively communicated to a corresponding functional device to be used with water.

The following is a further description of the deodorizing means.

Referring to fig. 1 to 10, in one embodiment, the filtering mechanism 3 has a water passing assembly 31 and a filter element assembly 32, the water passing assembly 31 stores running water, part of the running water can form a water curtain contacting with odor in an overflowing manner, and the filter element assembly 32 is at least partially immersed in the running water.

In the above embodiment, the water storage box 311 further includes a partition 312. Wherein the water storage box 311 has a water inlet 314 for connecting to an external water supply. The partition 312 is configured to partition the water storage box 311 into a water storage region and a water discharge region. Specifically, the water storage device further comprises an air inlet a and a water outlet 313. The air inlet A is disposed on the partition 312 and is laterally connected to the reservoir. The water outlet 313 communicates with a water drain capable of receiving liquid from the water storage area and draining the liquid in the water drain through the water outlet 313.

Accordingly, the water storage device achieves independent water storage or drainage of the liquid in the water storage box 311 between the water storage area and the drainage area by the partition 312. Wherein, dispose the water storage area of water inlet 314 and supply water to water storage box 311 after externally, be formed with ponding with the mode of cistern, and ponding can input to the drainage zone in and discharge through delivery port 313 to change the liquid in the water storage area, reach the purpose of high-efficient change retaining. In addition, one of the functions of the water storage device is that the water storage device can be beneficial to effectively dissolving and filtering the gas and the updated liquid continuously after the gas enters the water storage area. The side direction sets up the air inlet A at separator 312 for the outside gas is followed the box outside and is reacted with liquid in leading input to the impoundment district, and at gaseous output in-process, ponding in the impoundment district can be towards keeping away from air inlet A one side propelling movement along the following under gaseous drive, thereby makes things convenient for gas to enter into the impoundment district, and further fully contacts with undulant liquid, and the gas (like ammonia etc.) effect of detaching dissolved in water is especially showing.

In one embodiment, it is obvious that the guiding input of the external air and the sufficient contact with the water storage liquid can be further realized by opening an avoiding space in the water storage box 311. Specifically, the water storage box 311 has a first side. The first side has a first opening 3111 connected to the inlet A/isolator 312. The gas output space is avoided through the first opening 3111, so that the external gas can enter the box body in a guiding mode.

In particular, the water reservoir also includes a wind deflector 315. The partition 312 has a second side opposite the first side. The second side surface is in clearance fit with the wind deflector 315, and a gas passing channel which is communicated with the gas inlet A and allows external gas to enter the water storage area is formed between the second side surface and the wind deflector 315. On the premise that the wind shield 315 does not affect the overflow of the second side, the wind shield 315 capable of blocking and converging is arranged on the opposite side of the first opening 3111, so that the external gas is effectively converged at the two outlets, and the gas-liquid phase dissolution reaction is more efficiently and fully performed on the side. And, the wind screen 315 is configured to allow air to enter the water storage area along the two side edges and the upper edge thereof through the air inlet a, which facilitates guiding and lengthening of the flow path of the air inside the water storage box 311. In other embodiments, the wind deflector 315 may be configured with an air-containing space that is recessed to form part of the air inlet a to increase the residence time of air between the openings and the wind deflector 315 for efficient dissolution.

Still further, the second side has a second opening 3121 formed thereon which is not lower than the first opening 3111. So that the water curtain overflowing along the second opening 3121 is always higher than the first opening 3111. The second opening 3121 is not higher than each side of the partition 312, so that the wall height of the partition 312 where the second opening 3121 is located is always lower than other wall heights, and the height of the wind deflector 315 is always higher than the wall height of the partition 312. Further, the air inlet a is disposed between the second opening 3121 and the wind guard 315, and the liquid of the water storage area flows into the drain area along the top of the partition 312 in an overflowing manner. By the arrangement mode, when external air is not introduced, accumulated water in the water storage area is always formed on the wall side (the second opening 3121 side) at a low height in the form of a water curtain, the input air can be ensured to be right opposite to the wind shield 315 and be blocked by the wind shield 315, the input air is directly and fully contacted with the water curtain opposite to the wind shield 315, and the liquid seal air inlet A and the air passing channel are realized. Thus, the water curtain is formed only on the side of the second opening 3121 to uniformly and intensively perform the formation of the water film, the refresh rate thereof is faster and the reaction efficiency is significant. And when letting in external gas along air inlet A, ponding of cistern is blown to keeping away from air inlet A one side under the promotion of atmospheric pressure, at this moment, removes the liquid seal in second opening 3121 side for gas can follow the gas passage and get into in the water storage area. In particular, when gas is supplied, since the liquid does not flow out to the drain area from the second opening 3121 side, the water curtain type water overflow is performed from the wall side of the gas.

In a preferred embodiment, the partition 312 is configured as an annular partition wall to enclose the impoundment area in the water storage box 311, and such that a drain area is formed between an outer circumferential edge of the annular partition wall and an inner circumferential edge of the water storage box 311 in a gutter manner. Therefore, the arrangement mode can form effective water storage in the middle of the water storage box 311, and provide the water curtain to form the maximum area, and the water curtain is continuously formed around the outer wall of the annular partition wall. And the water storage areas and the water drainage areas are reasonably arranged to form a water diversion groove on the middle pool and the peripheral edge, so that the surface area of each water storage area is effectively regulated and controlled, and the direct contact with air is more favorable. The water guide groove has a water storage function, and the water discharge amount of the water outlet 313 is smaller than the overflow amount entering along the isolation part 312.

Wherein, after ponding has crossed isolation 312, with unnecessary ponding in order overflowing to the drainage area, during this period, the lateral surface that is located the isolation 312 place of drainage area one side can be formed with the water curtain constantly and continuously more renewedly for ponding in whole water storage box 311 carries out the high-efficient flow with the mode of running water along water storage area to drainage interval, can show water-soluble efficiency.

It should be noted that, the formation of the water curtain structure is realized under the action of high and low potential energy by accumulated water, that is, water flows down from top to bottom under the action of gravity to form a water film on the outer side surface of the isolation portion 312, and when the flowing air contacts with the water film of the wet curtain, the movable water flow can absorb water-soluble gas in the air and take away the water-soluble gas to flow down to the downstream to achieve the purpose of cleaning the air. In addition, the running water refers to accumulated water with a flowing water storage mode, and the running water can be selected to continuously form a water curtain so as to achieve a mode that the odor is dissolved in the water, the contact area is sufficient, and the adsorption effect is better. Furthermore, the flowing water is continuously generated due to the water inlet 314 arranged in the water storage area and the water outlet 313 arranged in the water discharge area, so that the continuous water supply and water discharge can be realized.

In addition, the water inlet 314 opens at the bottom of the impoundment area and the water outlet 313 opens at the bottom of the drainage area. So that the water storage area continuously enters water along the bottom until the accumulated water gradually submerges the height of the isolation part 312, and continuous water storage and supply are facilitated. In particular, the water inlet 314 is substantially larger than the water outlet 313.

In one embodiment, the height of the partition 312 is shorter than the height of the outer periphery of the water storage cartridge 311 as a whole. Such design mode for the cascade structure that forms is less than all the time and the arch sets up in the open-top of water storage box 311, does benefit to in the direct horizontal input of outside gas is to water storage box 311 and contact with the cascade of isolator 312 more high-efficiently, and ensures that the rivers that spill over do not lead to directly flowing out outside the box body.

Referring to fig. 5-7, in one embodiment, the filter element assembly 32 has a filter element body 321, and a bottom water absorbing structure and a top filtering structure disposed on the filter element body 321. The filter element body is detachably arranged on the water storage device, and the water absorption structure is at least partially immersed in the water storage area after the filter element body is installed in place.

The water absorption structure is detachably sleeved outside the filter element body, and the body is a shell structure allowing external air to enter the top along the bottom of the body. Specifically, the water absorption structure is a water absorption cotton cloth 322 vertically arranged outside the body in a curtain manner. The filter structure is configured as a filter cassette 323 with a carrying handle 3231 that can be stowed. One end of the water absorption cotton cloth 322 is immersed in the water storage area and is constructed into an annular ring which is sleeved at the bottom of the body in a clearance way. In addition, the filter box 323 at least contains pure diatom and/or activated carbon, and the side of the filter box 323 is provided with an air outlet B for connecting to the outside. It should be noted that the external air enters the inside through the bottom of the filter element assembly 32 (the gap between the absorbent cotton cloth 322 and the filter element body 321), enters the filter box 323 through the air holes/grooves formed in the filter element body 321, and is discharged out of the air outlet B after the filtering process.

Moreover, the filter is assembled on the water storage box 1 by inserting through the bottom of the filter element body 321, and the installation, placement, replacement and maintenance of the filter on the water storage device are more convenient in a portable operating mode. Further, it is noted that the absorbent cotton cloth 322 of the filter element assembly 32 is at least partially immersed in the running water so that it can absorb water, form a curtain to capture the odor in the air in a large area, and the odor is filtered again by diatom purification and activated carbon to become clean air to be discharged to the room outside the toilet, thereby allowing effective internal circulation of the air. Particularly, the filter element body 321 is in a T-shaped plate shape, the head part of the filter element body is provided with a hollow air hole/groove and a filter box 323 communicated with the air hole/groove, and the tail part of the filter element body is externally sleeved with a water absorption cotton cloth 322 so as to be easy to replace.

In addition, the deodorizing device further comprises an air suction duct communicated with the toilet chamber 11. The air suction duct is composed of a fan housing 4, the inlet side of the fan housing 4 is communicated with the toilet cavity 11, the outlet side of the fan housing 4 is provided with a centrifugal fan 41, and the centrifugal fan 41 can suck off odor in the toilet cavity 11 and directly convey the odor to the filtering mechanism 3 and is communicated with the air inlet A. The air suction duct is formed by the fan housing 4 independently, so that when the centrifugal fan 41 sucks off odor, the odor can be effectively transmitted along the inside of the fan housing 4 and cannot leak, and the odor in the toilet chamber 11 can be fully sucked off and filtered.

Specifically, the wind shielding plate 315 is disposed opposite to the centrifugal fan 81, and the wind shielding plate 315 is disposed at the back of the wall of the partition 312 on the same side and spaced from the bottom of the box body. The wall of the partition 312 of the side is lowered in height by the form of the second opening 3121. Wherein the diffusion coefficient of ammonia in air is 1.98 multiplied by 10^-5m²And/s, the ammonia removal effect is greatly met by the arranged wind shield 315 and the openings.
