Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as limiting or restricting the technical aspects of the present invention.

Therefore, these and other directional terms should not be construed as limiting terms.

The first embodiment is as follows:

fig. 1-5 are schematic views of a deodorizing device according to a first embodiment of the present invention.

Deodorizing device, including shell 1, set up the subassembly 2 that induced drafts in shell 1, store water chamber 11 and hybrid chamber 12, hybrid chamber 12 is located between subassembly 2 and the shell 1 that induced drafts, and the subassembly 2 that induced drafts is used for inhaling the foul smell, and the foul smell mixes the deodorization with steam in hybrid chamber 12, and the clean gas after the deodorization is discharged from shell 1.

Specifically, as shown in fig. 1-2, the front side of the housing 1 includes an air inlet 13, the air inlet 13 is in butt joint with the air inlet pipe 6, the upper side of the housing 1 is in butt joint with the air outlet pipe 7, the rear side of the housing 1 is provided with a driving motor 21 of the air suction assembly 2, the bottom surface of the housing 1 is sealed by a bottom plate 14, and a water storage cavity 11 (see fig. 4) is formed in a cavity between the bottom plate 14 and the lower edge of the air inlet 13.

As shown in fig. 2, the induced draft assembly 2 further includes an impeller 22 and a fine screen 23, the driving motor 21 is used for driving the impeller 22 to rotate, the fine screen 23 is covered on the periphery of the impeller 22, and both the impeller 22 and the fine screen 23 are installed inside the housing 1.

The impeller 22 has a cylindrical structure formed by a plurality of blades arranged at intervals around the center of a circle, and the fine screen 23 has a plurality of micropores.

In the first embodiment, the impeller 22 is used to suck the external odor into the mixing chamber 12 while rotating, and the odor is sucked into the mixing chamber 12 (see fig. 5) through the air inlet duct 6 and the air inlet 13.

Because a certain amount of water is stored in the water storage cavity 11, certain water mist or water vapor is formed in the mixing cavity 12, after the odor enters the mixing cavity 12, the odor and the water vapor are mixed and deodorized in the mixing cavity, and the deodorized clean gas is discharged from the air outlet pipe. The main substances (ammonia gas, hydrogen sulfide and the like) in the odor can be dissolved in water and can possibly be dissolved in the water to react with each other, so that the odor is decomposed and filtered, and the clean gas with the odor removed is discharged to the outside of the deodorization device from the air outlet pipe 7 above, thereby realizing the deodorization process.

In a variation of the first embodiment, the impeller 22 may be located closer to the air inlet 13; the fine mesh 23 is positioned behind the impeller 22, the impeller 22 blows the odor to the fine mesh 23, and the fine mesh 23 can scatter the odor through the fine holes of the fine mesh 23 so that the water is more sufficiently mixed. Alternatively, the impeller 22 may be replaced by a fan blade, which is located at the front side of the fine screen 23 and closer to the air inlet 13, and blows the odor toward the fine screen 23.

Alternatively, the impeller 22 may be located at the rear side of the fine screen 23 to suck the odor gas to the fine screen 23.

Further, as shown in fig. 4-5, the impeller 22 and the fine screen 23 partially enter the water storage chamber 11.

The impeller 22 stirs the water stored in the water storage chamber 11 during the rotation, the odor permeates the fine screen 23 and is mixed with the water vapor in the mixing chamber 12, the main substances in the odor are filtered and dissolved, and the odor is discharged from the air outlet pipe 7 at the upper part of the mixing chamber 12 after being filtered and cleaned. The fine mesh 23 may break down the odor passing between the blades of the impeller 22 through the fine holes of the fine mesh 23 so that the water is more sufficiently mixed. The water droplets adhered to the impeller 22 are separated from the gas by the centrifugal force generated by the rotation of the impeller 22, and the separated water droplets are thrown to the inner side wall of the casing 1 and downwardly dropped into the water storage chamber 11 at the bottom, and then recycled for being agitated by the impeller 22 to complete the deodorization process.

Further, as shown in fig. 3-4, the lower portion of the air inlet 13 is provided with a water baffle 3. The water baffle 3 is positioned at the lower part of the connection part of the air inlet pipe 6 and the air inlet 13. In this embodiment, the water baffle 3 can be directly connected to the air inlet pipe 6. Alternatively, the splash plate 3 may also be directly connected to the housing 1.

The water baffle 3 has a certain height, so that the bottom of the mixing cavity 12 can store a certain amount of water, and the mixing cavity 12 is communicated with the water storage cavity 11. The capacity for water storage is increased and the impeller 22 and the fine screen 23 are partially immersed below the water level L. The water baffle 3 can prevent water from splashing out of the air inlet pipe 6 during the process of stirring water by the impeller 22.

Optionally, the air suction assembly 2 can be replaced by a fan blade similar to a fan, a fine screen is not arranged, the fan blade can not be immersed in water, water in the water storage cavity 11 is naturally volatilized to form high-humidity water vapor in the mixing cavity 12, the air suction assembly 2 sucks external odor into the mixing cavity 12, the odor and the water vapor are fully mixed through stirring of the fan blade, and purified clean air is discharged from the air outlet pipe 7 above.

Further, as shown in fig. 5, the air outlet pipe 7 is disposed obliquely upward from the mixing chamber 12, and a filter screen (not shown) is provided at the rear end of the air outlet pipe 7.

When the deodorized gas is discharged from the air outlet pipe 7, since the rapidly passing gas may also carry a small amount of residual fine mist and water droplets into the air outlet pipe 7, when the fine mist and water droplets adhere to the inner wall of the air outlet pipe 7 to form water droplets, they flow back into the mixing chamber 12 along the inclined pipe wall and finally into the water storage chamber 11. The water mist and the fine water drops are prevented from being discharged along the air flow and accumulated near the deodorization exhaust window of the product. A filter screen is additionally arranged in a pipeline at the rear end of the air outlet pipe 7 to block fine water drops which can be discharged along with air flow.

In the first embodiment, the odor is sucked from the air inlet pipe 6 and enters the mixing chamber 12 through the air inlet 13, the odor is fully mixed with the water vapor in the mixing chamber 12, the main substances (ammonia gas, hydrogen sulfide and the like) in the odor are dissolved in the water, the odor is separated from the water vapor at the upper part of the mixing chamber 12 and is discharged from the air outlet pipe 7 above, and the odor removing process is completed.

In this embodiment, since the water or mist is agitated by the high speed rotation of the impeller 22 during the deodorization, when the deodorization function is activated for a long time, the fine water droplets may be discharged together with the air flow, and the water stored in the water storage chamber 11 is reduced as the deodorization time is extended, thereby reducing the sufficient mixing degree of the odor and the water and affecting the deodorization effect, the water can be regularly and quantitatively supplied to the water storage chamber 11 within a certain time range in terms of control so as to maintain the stable deodorization efficiency. When the deodorization is finished, the water mixed with the odor main substance is stored in the water storage cavity 11, and at the moment, the product starts to enter water again through the water inlet 111 at one side of the water storage cavity 11 so as to discharge the water mixed with the odor main substance, thereby achieving the cleaning effect.

In the embodiment, because the odor and the water vapor can be fully mixed, the deodorization efficiency is high; and the replacement cost of water is lower, and the use cost of deodorization can be reduced.

As shown in fig. 6 to 7, a modification of the first embodiment is shown. The rectangular housing and floor 14 forming the water holding chamber 11 in the first embodiment are omitted. The housing 1 forms a ring of cylindrical cavities only outside the impeller 22.

Because the rear end of the air inlet pipe 6 and the front end of the mixing chamber 12 are provided with the sealing structure 8 which can be a waterproof film and can prevent the water stored at the bottom of the mixing chamber 12 from leaking out of the deodorization device, when the deodorization device enters water, the water can directly enter the mixing chamber 12 through the water inlet 111 at the bottom of the casing 1 of the deodorization device, so that the rectangular casing and the bottom plate 14 at the lower part can be eliminated, the structural design is simplified, and the overall height of the deodorization device is reduced. In the modification, the bottom of the mixing chamber 12 corresponds to the water storage chamber 11, and the impeller 22 and a part of the fine screen 23 are immersed in the water storage chamber 11.

Example two:

as shown in fig. 8 to 11, unlike the first embodiment: the deodorizing device also comprises a spraying component 4, wherein the spraying component 4 sucks water from the water storage cavity 11 and sprays water mist towards the air suction component 2; the impeller 22 and the fine screen 23 are not immersed in water, but water is sprayed toward the impeller 22 and the fine screen 23 through the spray assembly 4.

Specifically, the spraying assembly 4 comprises a water pump 41, a water pump inlet pipe 42, a water pump outlet pipe 43 and a spraying head 44, wherein the water pump inlet pipe 42 is connected with the water storage cavity 11 and the water pump 41, the water pump outlet pipe 43 is connected with the water pump 41 and the spraying head 44, the spraying head 44 is positioned inside the impeller 22, the spraying head 44 enters the shell 1 from the air inlet pipe 6 and then extends into the center of the impeller 22, and the spraying head can radially spray water mist towards the blades of the impeller 22.

As shown in fig. 10, when deodorizing, the odor sucked from the air intake duct 6 must first permeate through the fine mesh 23 outside the impeller 22 when passing through the blade gaps of the impeller 22, and the main function of the fine mesh 23 is to disperse the sucked odor as much as possible through the fine holes, to sufficiently mix the air with the mist and water in the mixing chamber 12 by the high-speed rotation of the impeller 22, to filter and dissolve the main substances in the odor, and to discharge the deodorized air from the air outlet duct 7 at the upper part of the mixing chamber 12 after the filtering and cleaning. The water droplets attached to the impeller 22 are separated from the gas by the centrifugal force generated by the rotation of the impeller 22, and the separated water droplets are thrown to the inner side wall of the mixing chamber 12 and slide down to the water storage chamber 11 so that the water pump 41 sucks the water again to be sprayed into the mixing chamber 12 in a circulating manner, thereby completing the deodorization process.

As shown in fig. 10, the mixing chamber 12 is isolated from the water storage chamber 11, and a plurality of small holes 121 are opened at the bottom of the mixing chamber 12. So that when the deodorization device is filled with water, the water can enter the bottom of the mixing cavity 12 from the water storage cavity 11 through the small hole 121; when the deodorizing means is operated, the water in the mixing chamber 12 can flow back to the water storage chamber 11 through the small hole 121.

In a modification of the second embodiment, a dedicated water pump chamber may be provided for supplying water to the water pump 41, and the water pump inlet pipe 42 connects the water pump chamber and the water pump 41.

Alternatively, the spray head 44 is not necessarily located inside the impeller 22, and may be located on the front side or the rear side of the impeller 22, and may spray water mist toward the inside of the impeller 22.

Example three:

as shown in fig. 12 to 16, the difference from the second embodiment is: the deodorizing device further comprises a transmission assembly 5, wherein the transmission assembly 5 comprises a motor driving gear 51, an intermediate transmission shaft 52, an intermediate transmission gear 53, an impeller transmission gear 55 and an impeller transmission shaft 54;

the motor driving gear 51 is installed on the driving shaft 24 of the driving motor 21, the intermediate transmission gear 53 is installed on the intermediate transmission shaft 52, the impeller transmission gear 55 is installed on the impeller transmission shaft 54, the motor driving gear 51 is meshed with the intermediate transmission gear 53 and the impeller transmission gear 54, and the intermediate transmission gear 53 is used for driving the water pump 41 to rotate.

When the driving motor 21 rotates, the driving shaft 24 is driven to rotate, the driving shaft 24 drives the motor driving gear 51 to rotate, the motor driving gear 51 simultaneously drives the intermediate transmission gear 53 and the impeller transmission gear 55 to rotate, the intermediate transmission gear 53 is used for driving the water pump 41 to rotate, and the impeller transmission shaft 54 is used for driving the impeller 22 to rotate.

In this embodiment, by adding corresponding driving and transmission gears and driving shafts, while the driving motor 21 drives the impeller 22 to rotate and suck odor, the driving motor 21 also transmits the driving force to the water pump 41 through the intermediate transmission gear 53, and the water pump 41 can simultaneously suck water from the water storage chamber 11 and spray the water to the mixing chamber 12 through the spray head 44. The scheme of integrating the water pump 41 and the deodorization device into a whole is realized, and the internal space and the cost of the product are saved.

Further, as shown in fig. 13, the water pump 41 is a gear pump, the gear pump includes a lower water pump transmission shaft 411, a lower water pump transmission gear 412, an upper water pump transmission shaft 413, and two front water pump gears 414, the intermediate transmission gear 53 is engaged with the lower water pump transmission gear 412, the lower water pump transmission gear 412 is mounted on the lower water pump transmission shaft 411, the lower water pump transmission shaft 411 drives the upper water pump transmission shaft 413 to rotate, one of the front water pump gears 414 is mounted on the upper water pump transmission shaft 413, and the two front water pump gears 414 are engaged with each other.

When the intermediate transmission gear 53 drives the water pump lower transmission gear 412 to rotate, the water pump lower transmission gear 412 drives one of the water pump front gears 414 to rotate through the water pump lower transmission shaft 411 and the water pump upper transmission shaft 413. As shown in fig. 15, the two water pump front gears 414 rotate in opposite directions, and water inlet and outlet of the gear pump are realized.

The water pump 41 of the deodorization device is a gear pump structure, when the driving motor 21 starts to work, on one hand, the driving motor 21 drives the intermediate transmission gear 53, the adjacent impeller transmission gear 55 and the impeller transmission shaft 54 to make the impeller 22 rotate at high speed, so as to suck odor, meanwhile, the middle transmission gear 53 and the middle transmission shaft 52 drive the matched water pump lower transmission gear 412 and the water pump lower transmission shaft 411 to transmit power to two water pump front gears 414 of the gear pump, due to the opposite rotation direction of the two water pump front gears 414, water can be sucked from the water storage cavity 11 through the water pump water inlet pipe 42 from the gear pump water suction cavity 418 at the left side, then, the water is pressurized, extruded from a water outlet cavity 419 of the gear pump on the right side, supplied to the spray head 44 through a water outlet pipe 43 of the water pump, and sprayed into the mixing cavity 12, so that the water circulates between the water storage cavity 11 and the gear pump, thereby performing a deodorization function.

Example four:

as shown in fig. 17-19, the impeller 22 comprises two layers of coaxially arranged blade sets of different diameters, each layer of blade set being covered by a ring of fine mesh screen 23.

Specifically, as shown in fig. 17, the fine screen 23 includes an inner impeller screen 231 and an outer impeller screen 232, and the diameter of the inner impeller screen 231 is smaller than that of the outer impeller screen 232.

As shown in fig. 19, in order to improve the deodorization efficiency, the odor and the water are more sufficiently stirred and mixed in the mixing chamber 12, and two-stage filtration is realized. When the odor is sucked into the mixing chamber 12, most of the odor needs to pass through the two layers of fine screens, the mixing chamber 12 is filled with water, and a water curtain is formed near the two layers of fine screens 23 under the high-speed rotation and stirring of the impeller 22, so that the odor is continuously filtered twice, and the deodorization efficiency is improved.

Alternatively, the impeller and the fine screen may be formed in three or more layers. According to the difference of product space, the diameter of the impeller can be increased, and multi-stage blades with different diameters and corresponding screens are coaxially arranged on one impeller, so that multi-stage filtration is realized.

Example five:

as shown in fig. 20 to 21, the intelligent toilet includes a base 10 and a cover 20, and further includes a deodorization device disposed inside the base 10 and the cover 20.

Further, the air inlet end 61 of the air inlet pipe 6 is connected with the base 10, and the air outlet end 71 of the air outlet pipe 7 extends out of the side surface of the cover 20.

The odor is sucked into the air inlet pipe 6 from the air inlet end 61 extending out of the base 10, then is deodorized in the deodorizing device, and is discharged from the air outlet end 71 of the air outlet pipe 7 after deodorization, and the air outlet end 71 extends out of the side surface of the machine cover 20, so that the purified air is discharged to the outside of the intelligent toilet from the side surface, and the deodorizing process is completed.

Optionally, an electrolytic component can be added to electrolyze water, and hypochlorous acid water after electrolysis is mixed with odor, so that the deodorization effect is better.

According to the invention, odor brought by a user when the user goes to a toilet is fully stirred and mixed with water for filtering, and main substances (ammonia gas, hydrogen sulfide and the like) in the odor are dissolved in the water or are filtered by the water for deodorization, so that the problems that the odor passes through the deodorization module too fast and the deodorization efficiency is not high when the active carbon oxidation module is used for deodorization at present, and the deodorization efficiency is reduced and the module function is possibly failed to cause the need of regularly replacing the descaling module after the deodorization module is used for a period of time by the user are solved.

In addition, as the main substances in the odor are easy to dissolve in water or can be filtered by water for deodorization, compared with the mode that the main substances in the odor are deodorized by adsorption of activated carbon or by the oxidation decomposition of the attached oxides, the deodorization device is more direct and efficient, the deodorization efficiency is improved, and the cost is saved.

The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
