Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a deodorization system for a smart toilet. Background Technology

[0002] With the development of smart home technology, smart toilets have become widely used in ordinary households. However, smart toilets on the market are not equipped with deodorization systems to address the odors generated during toilet use. During the use of such products, the foul odors generated in the toilet bowl can easily spread directly into the bathroom space. Usually, the bathroom exhaust fan is used to remove the odors and air fresheners are placed in the bathroom to freshen the air.

[0003] Exhaust fans are used to treat odors that have spread into the air of the bathroom. The odor of excrement can spread directly from the toilet bowl into the surrounding space of the bathroom, causing users to directly inhale the odorous gas. In addition, there is usually a certain distance between the exhaust fan and the toilet, making it difficult to create air convection around the toilet in time. The odorous gas will first spread over a large area in the bathroom before being gradually drawn away by the exhaust fan, resulting in low overall deodorization efficiency.

[0004] In summary, traditional smart toilets have significant shortcomings in odor control, and the development of smart toilets with deodorization functions has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a deodorization system for smart toilets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deodorization system for an intelligent toilet, comprising a toilet body and a toilet core. The toilet core is installed behind the toilet bowl of the toilet body. An air inlet duct is provided at one end of the toilet core near the toilet bowl, connecting to the interior of the toilet bowl. A fan chamber is connected to the end of the air inlet duct, and a fan for extracting odorous gases is installed inside the fan. A treatment chamber is provided on the air outlet side of the fan, and a deodorization box is installed in the treatment chamber. The air outlet of the fan is connected to the air inlet of the deodorization box, and the air outlet of the deodorization box is set to correspond to the exhaust hole on the rear wall of the toilet core, so that the gas treated by the deodorization box is discharged into the outside air through the exhaust hole.

[0007] The deodorizing box is formed by a box cover and an outer box. The front end of the outer box is provided with an air inlet that connects to the air outlet of the fan, and the rear end of the outer box is provided with an air outlet that connects to the exhaust hole on the rear wall of the toilet bowl.

[0008] An air passage is provided between the fan cavity and the processing cavity. The air passage is connected to the fan outlet and the air inlet of the outer casing, and the length and width of the three are adapted to each other.

[0009] The outer box contains an air filter layer, an activated carbon layer, and an aromatherapy deodorizing layer, all arranged at intervals along the gas flow direction. The interior of the outer box has positioning slots, and the air filter layer, activated carbon layer, and aromatherapy deodorizing layer are sequentially and detachably assembled into the outer box through the positioning slots.

[0010] The inner side of the rear wall of the toilet core is connected to the exhaust port, and the air guide duct extends to the air outlet of the deodorizing box and connects with the air outlet.

[0011] The outer casing of the fan has mounting ears, and the bottom wall of the fan cavity is provided with a mounting seat. The fan is fastened to the fan cavity by being secured in the mounting seat through the mounting ears.

[0012] The top surface of the fan and the upper inner wall of the fan cavity are spaced apart to form an upper flow space, and the bottom wall of the fan cavity is located below the fan and has a sinkhole to form a lower flow space. The upper flow space and the lower flow space are connected to the air inlet duct.

[0013] The fan is electrically connected to the main control circuit board inside the toilet mechanism via a wire to receive control signals and obtain operating power.

[0014] The toilet bowl mechanism has a replacement opening on the top surface corresponding to the cover of the box, so that the cover of the deodorizing box can be opened to replace the air filter layer, activated carbon layer and aromatherapy deodorizing layer.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application, by setting up a deodorization system inside the toilet bowl, promptly extracts and treats most of the odorous gases at the source of odor generation. Through the air inlet duct near the toilet bowl end of the toilet bowl, a fan at the end of the air inlet duct directly extracts the odorous gases from inside the toilet bowl. Activating the fan draws the odorous gases from inside the toilet bowl into the air inlet duct and guides them into the fan chamber. Subsequently, the fan discharges the odorous gases from its outlet into the deodorization box, where an air filter layer, an activated carbon layer, and an aromatherapy deodorization layer sequentially filter and purify the odorous gases before discharging them into the outside air through the exhaust port of the toilet bowl. This allows for timely purification of odorous gases at the source, solving the problem of traditional methods where odors diffuse first and then are treated, significantly reducing the direct inhalation of odors by users, and achieving immediate treatment of odorous gases.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1-11As shown, a deodorizing system for a smart toilet consists of a toilet body 1 and a toilet mechanism 2. The toilet mechanism 2 includes a base and a corresponding upper cover. A recessed area is provided in the center of the front end of the base. The toilet body 1 has a receiving notch at the top of the rear wall of the toilet bowl, and there is an installation space behind the toilet bowl. During assembly, the periphery of the upper end of the base is connected to the top surface of the installation space. The main body of the base, i.e., the cavity housing the mechanism parts, is placed within the installation space, and the front recessed area is fitted into the receiving notch of the toilet bowl. The upper cover of the toilet mechanism is higher than the toilet body. An air inlet 21 communicating with the interior of the toilet bowl is provided at the end of the recessed area of ​​the toilet mechanism 2 near the toilet bowl. This air inlet 21 is formed by two sets of vertical walls 224 spaced apart on the bottom wall of the recessed area, enclosed by a sealing upper plate. The air inlet 21 has an air inlet that is lower than the top surface of the toilet bowl and located inside the toilet bowl.

[0020] The air inlet duct 21 is connected to a fan chamber 22 at its end. The fan chamber is formed by a recessed chamber in the base of the toilet seat 2, which is enclosed by a sealing upper plate. The upper plate of the fan chamber 22 and the upper plate of the air inlet duct 21 are integrally formed. The upper end face of the fan chamber is flush with the upper end face of the air inlet duct. Both upper end faces have raised ribs 223 on their inner sides. The bottom end of the upper plate 221 has a recess 222 corresponding to the raised ribs 223. The upper plate 221 is fitted into the recess 222 by the raised ribs to form a sealed fan chamber and air inlet duct, reducing airflow leakage.

[0021] The blower chamber 22 houses a blower 220 for extracting odorous gases. The blower's inlet faces downwards, while its outlet faces the rear of the toilet bowl. This blower is a conventional turbine blower. The outer casing of the blower 220 has mounting ears 215, and the bottom wall of the blower chamber 22 has a corresponding mounting base 216. This mounting base is formed by two sets of spaced-apart limiting walls, each with a limiting notch on its inner side. The blower 220 is secured to the blower chamber 22 by engaging the mounting ears 215 within the limiting notches of the mounting base 216. To ensure a more stable connection between the blower and the toilet bowl base, a plug-in post can be installed inside the mounting base, and a plug-in hole can be provided on the blower's mounting ears, allowing the plug-in post to be inserted into the plug-in hole.

[0022] The depth of the fan cavity is greater than the thickness of the fan. The top surface of the fan 220 is spaced from the upper inner wall of the fan cavity to form an upper flow space. The bottom wall of the fan cavity 22 is located below the fan 220 and has a recessed groove 217 to form a lower flow space. The upper flow space and the lower flow space are connected to the air inlet duct 21. The upper flow space can buffer and equalize the airflow entering through the air inlet duct, and at the same time provide heat dissipation space for the fan. Under the negative pressure suction of the fan, the airflow in the fan cavity is drawn into the air inlet of the fan through the lower flow space, and after being pressurized by the fan, it is discharged from the air outlet to the deodorizing box.

[0023] A treatment chamber 23 is provided on the air outlet side of the fan 220. The treatment chamber 23 is equipped with a deodorizing box 24. The air outlet of the fan 220 is connected to the air inlet of the deodorizing box 24. The air outlet of the deodorizing box 24 is set to correspond to the exhaust hole 29 on the rear wall of the toilet core, so that the gas treated by the deodorizing box 24 is discharged into the outside air through the exhaust hole 29.

[0024] The air inlet duct 21, the fan chamber 22, the fan 220 installed in the fan chamber, the treatment chamber 23, and the deodorizing box 24 installed in the treatment chamber 23 together form a one-way deodorization system. When the user sits on the toilet, the odorous gas generated during the toilet process can be promptly drawn by the fan into the deodorizing box for purification and filtration.

[0025] Specifically, the deodorizing box 24 is formed by a box cover 25 and an outer box 26. The front end of the outer box 26 is provided with an air inlet 27 that connects to the air outlet side of the fan 220, and the rear end of the outer box 26 is provided with an air outlet 28 that corresponds to and communicates with the exhaust hole 29 on the rear wall of the toilet bowl. The fan chamber 22 and the treatment chamber 23 are separated by a partition, and an air passage 210 is provided on the partition. The air passage 210 is connected to the air outlet of the fan 220 and the air inlet 27 of the outer box 26, and the length and width of the three are matched to make the connection between the fan outlet, the air inlet of the outer box and the air passage more tight, so as to prevent odor-containing gas from leaking from the interface to other areas inside the bowl, and ensure that the odor gas can be introduced into the deodorizing box.

[0026] The outer casing 26 contains an air filter layer 211, an activated carbon layer 212, and an aromatherapy deodorizing layer 213, all arranged at intervals along the gas flow direction. The air filter layer is a HEPA filter, which first filters and purifies odorous gases. Both the activated carbon layer and the aromatherapy deodorizing layer are composed of honeycomb breathable panels and breathable meshes. The honeycomb breathable panels have multiple sets of through holes, and the breathable meshes are installed at the front and rear ends of the breathable panels. The through holes of the honeycomb breathable panels in the activated carbon layer are filled with columnar activated carbon particles to further adsorb and filter odors from the initially filtered gas. The through holes of the honeycomb breathable panels in the aromatherapy deodorizing layer are filled with aromatherapy particles to further decompose odors and release fragrance. It should be noted that the air filter layer, activated carbon layer, and aromatherapy deodorizing layer are all existing technologies; conventional products on the market of the same type can meet the filtration and odor treatment needs of this toilet deodorizing device.

[0027] The outer box 26 has three sets of positioning slots 219 on each of its left and right inner side walls. The three sets of positioning slots 219 on the left side wall correspond to the three sets of positioning slots 219 on the right side wall. The edge dimensions of the air filter layer, activated carbon layer, and aromatherapy deodorizing layer are all adapted to the depth of the positioning slots. The air filter layer, activated carbon layer, and aromatherapy deodorizing layer can all be vertically inserted into the positioning slots 219 one by one from the top opening of the outer box 26, and can be detached and assembled in the positioning slots 219 for easy daily replacement.

[0028] Specifically, each of the left and right outer walls of the top cover 25 of the toilet bowl is provided with a pivot, and the left and right sides of the outer box 26 are provided with corresponding rotating holes. The top cover 25 of the toilet bowl is rotatably connected to the outer box 26 through the cooperation of the pivot and the rotating holes. The top cover of the toilet bowl 2 has a replacement port 218 corresponding to the top cover 25 of the toilet bowl. A decorative cover is also installed on the top cover. The back of the decorative cover has multiple sets of protrusions, and the top surface of the top cover has multiple sets of matching positioning grooves. The decorative cover is detachably installed on the top cover through the cooperation of the protrusions and positioning grooves, serving the purpose of decoration and covering the replacement port. When the filters need to be replaced, the decorative cover on the toilet bowl 26 is removed, and the top cover of the toilet bowl is flipped open through the replacement port to replace the aromatherapy deodorizing layer, the activated carbon layer, and the air filter layer.

[0029] The toilet bowl mechanism has an air guide duct 214 connected to the exhaust port 29 on its inner rear wall. The air guide duct 214 extends towards and connects to the air outlet 28 of the deodorizing box 24. The treated air is discharged through the air guide duct to the exhaust port, preventing the purified air from escaping inside the toilet bowl mechanism. The exhaust port is located on the rear wall of the upper cover of the toilet bowl mechanism, exposing it to the toilet body and ensuring that the fragrance gas from the aromatherapy deodorizing layer can diffuse into the air.

[0030] The fan 220 is electrically connected to the main control circuit board inside the toilet bowl mechanism 2 via a wire to receive control signals and obtain operating power. The main control circuit board can control the start and stop of the fan through a human body sensing module. When the system senses that a user has sat on the toilet, it starts the fan and draws odorous gas into the deodorizing box to purify and filter the odor gas at its source. After the user leaves the toilet, the fan continues to operate for about 1 minute to keep the bathroom fresh. It should be noted that the electrical connection between the fan and the main control circuit board, as well as the processing of the control signals, are existing technologies and will not be described in detail in this application.

[0031] The deodorization system works as follows: When a user uses the smart toilet, the main control circuit board inside the toilet bowl detects the user sitting down via a human body sensor module and sends a start signal to the fan, which then begins operation. Odor-causing gases generated in the toilet bowl are drawn into the fan chamber through the air inlet and air duct under the negative pressure of the fan, and are then sucked in by the fan. The fan then draws the odor-causing gases from its outlet through the vent into the air inlet of the deodorization box. Inside the deodorization box, the odor-causing gases pass sequentially through an air filter layer, an activated carbon layer, and an aromatherapy deodorization layer. The air filter layer initially filters the odors from the gas; the activated carbon layer removes odor molecules through adsorption; and the aromatherapy deodorization layer releases aroma molecules and neutralizes some of the odors. The purified gas is then discharged from the air outlet of the deodorization box, and through the air duct, it is discharged into the exhaust vent on the rear wall of the top cover, ultimately reaching the outside air.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
