Description

Technical Field

[0001] The present invention relates to the field of bathroom fixtures, and in particular to a device with a fragrance function and a method for controlling the fragrance of a toilet. Background Art

[0002] The existing smart toilet fragrance module integration solution has the following problems: First, the module needs to be equipped with an independent air pump device to drive the fragrance diffusion. However, the air pump as a core power component leads to high overall costs. At the same time, an independent control module and power module are required, further increasing the system complexity and manufacturing costs.

[0003] Secondly, the internal space layout of smart toilet lids is already highly compact, making it difficult to effectively arrange the existing fragrance module's physical structure. Embedding the fragrance component within the one-piece ceramic body is also challenging. The volume occupied by the air pump, liquid storage container, and supporting piping conflicts with the narrow installation space, severely restricting the feasibility of module integration. Furthermore, the independently installed fragrance module lacks deep synergy with the main toilet functions, and its control system, air supply device, and toilet operating status cannot form a closed-loop linkage. Summary of the Invention

[0004] The main purpose of the present invention is to overcome the defect in the prior art that the fragrance module needs to be additionally equipped with an independent air pump, control module and power supply, etc., which increases the complexity and manufacturing cost of the toilet system. A device with fragrance function and a fragrance control method for a toilet are proposed. The fragrance module is integrated with the cover structure, sharing the original air pump and control module of the toilet, etc., avoiding repeated configuration of hardware resources, thereby realizing the functional integration and intelligent triggering of fragrance release and toilet usage scenarios.

[0005] The present invention adopts the following technical solutions:

[0006] A device with a fragrance function is installed on a toilet and includes an air pump, a foam module and a control module; it also includes the fragrance module and a switching valve; the input end of the switching valve is connected to the output end of the air pump, one of the output ends of the switching valve is connected to the air inlet end of the foam module, and the other output end of the switching valve is connected to the air inlet of the fragrance module; the control module is connected to the air pump and the switching valve to control the air pump to start, and to control the switching valve to switch on the foam module to realize the foam function or to connect to the fragrance module to realize the fragrance spraying function.

[0007] The fragrance module includes a liquid storage chamber, a mixing chamber, a Venturi tube, and a liquid inlet tube. The liquid storage chamber is used to store liquid fragrance. One end of the Venturi tube serves as an air inlet and is connected to the output end of the switching valve, and the other end of the Venturi tube serves as an air outlet and communicates with the mixing chamber. One end of the liquid inlet tube communicates with the liquid storage chamber, and the other end communicates with the Venturi tube near the air outlet. The mixing chamber is also provided with a fragrance spraying port. The gas entering from the air inlet of the Venturi tube is accelerated and then enters the mixing chamber. A negative pressure is formed near the air outlet of the Venturi tube to drive the liquid inlet tube to suck the fragrance from the liquid storage chamber. The fragrance enters the mixing chamber, mixes with the gas and is dispersed, and then forms a fragrance and is sprayed out from the fragrance spraying port.

[0008] The fragrance module is provided with a main body and an upper cover. The main body is provided with a liquid storage chamber. The upper cover is detachably fitted with the main body and is provided with a mixing chamber, a Venturi tube, a liquid inlet tube, and a fragrance spraying port. A fragrance spraying pipe can also be connected to the fragrance spraying port.

[0009] The fragrance module is installed on the plate body of the toilet. The plate body includes a bottom plate and a cover body. The fragrance module is close to the front side or the rear side or the left side or the right side or the middle of the bottom plate. The air outlet end of the fragrance module can be located at the front side or the rear side or the left side or the right side or the middle of the bottom plate. The cover body is fixed on the bottom plate and is provided with an opening at the position where the fragrance module is located. A detachable closure is provided at the opening.

[0010] A fragrance control method for a toilet is realized by using a toilet with a fragrance module. When the toilet detects that a user is about to use the toilet, it controls the start of the fragrance spraying function of the fragrance module. When the toilet detects that the user is using the toilet, it controls the fragrance module to execute different gear fragrance spraying functions according to the usage situation. When the toilet detects that the user has finished using, it controls the closing of the fragrance spraying function of the fragrance module.

[0011] The plate body is connected with a cover plate. When the toilet detects that the user is approaching or the toilet detects that the cover plate changes from closed to open, it is determined that the user is about to use the toilet and the fragrance spraying function is started. After a set time length or until the user sits down, the control stops the fragrance spraying function. When it is detected that the user has sat down, after a period of time, the control starts the fragrance spraying function and enters the first gear.

[0012] In the first gear, the fragrance spraying function operates in a first periodic cycle mode. In each cycle period, the fragrance spraying duration is t1 seconds, and then the fragrance spraying stops for t2 seconds.

[0013] The fragrance spraying function also includes a second gear. In the second gear, the fragrance spraying function operates in a second periodic cycle mode. In each cycle period, the fragrance spraying duration is t3 seconds, and then the fragrance spraying stops for t4 seconds. When the toilet detects that the user uses the cleaning function, it controls the fragrance spraying function to enter the second gear, and when the cleaning function ends, it controls the fragrance spraying function to enter the first gear.

[0014] The fragrance spraying function further includes a third gear. In the third gear, the fragrance spraying function operates in a third periodic cycle mode. In each cycle period, the fragrance spraying duration is t5 seconds, and then the fragrance spraying stops for t6 seconds. When the toilet detects that the user uses the drying function, it controls the fragrance spraying function to enter the third gear, and when the drying function ends, it controls the fragrance spraying function to enter the first gear.

[0015] The toilet is also provided with a fragrance indicator light and a voice module. When the fragrance spraying function is turned on, the fragrance indicator light lights up or flashes and the voice module broadcasts a set sound effect. The color of the fragrance indicator light corresponds to different gears of the fragrance spraying function. The control module can also receive control commands from other mobile terminals to set the opening time and closing time of the fragrance spraying function.

[0016] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, the switching valve is used to realize the air supply switching of the single air pump to the foam module and the fragrance module, which simplifies the pipeline structure and avoids gas interference between the two functions. The foaming function and the fragrance spraying function are integrated into the internal space of the toilet (such as the board body or the ceramic body). The foam generated by the foam module can effectively cover the surface of the toilet bowl, playing a role in cleaning and preventing splashing. The fragrance sprayed by the fragrance module can cover up the odor and create a fresh and comfortable use environment, providing a more comfortable and pleasant use experience for users.

[0018] 2. In the present invention, through the design of the Venturi tube and the mixing chamber of the fragrance module, the negative pressure effect generated by gas flow is used to realize the automatic suction and efficient mixing of the fragrance agent. Without additional power devices, the fragrance agent and gas can be fully dispersed and fused, improving the uniformity of fragrance diffusion. The detachable split structure of the main body and the upper cover is convenient for cleaning, maintenance or replacement of components, extending the service life of the module. The fragrance spraying pipeline can be flexibly adapted to different layout orientations of the board body, enhancing the space adaptability and installation freedom.

[0019] 3. In the present invention, the device can be installed on the board body of the toilet. The board body is divided into a bottom board and a cover body. An opening is provided on the cover body, so that the fragrance agent of the fragrance module can be replenished or the module can be replaced without disassembling the whole cover body, significantly improving the maintenance convenience. The overall structure relies on the original installation position of the toilet cover plate, and the function can be expanded without changing the structure of the ceramic body, having good adaptability and installation convenience.

[0020] 4. In the present invention, through the fragrance control method, it adapts to the diversified function configurations of the toilet, realizes the intelligent linkage between the fragrance release and the user's usage status, and improves the toilet environment experience. Combining the detection of user behaviors such as approaching and sitting on the toilet to automatically trigger the fragrance function, reducing unnecessary fragrance volatilization, and taking into account both the hygiene requirements and the usage efficiency of the fragrance agent.

[0021] 5. In the present invention, by intelligently perceiving the user's functional requirements, the fragrance spraying gear is dynamically adjusted to adapt to different usage scenarios. When the cleaning or drying function is started, the fragrance release intensity is automatically increased to offset in real time the peculiar smell that may be caused by water vapor or air flow; after the function ends, the basic fragrance coverage is restored to maintain the environmental freshness. This logic enables the fragrance intensity to be linked in real time with the changes in the space environment, avoiding waste caused by a single concentration, ensuring seamless connection of the odor experience at each stage, and simplifying the user operation through the function association trigger mechanism, taking into account both environmental comfort and resource utilization efficiency.

[0022] 6. In the present invention, the user's perception of the fragrance state is enhanced through multi-dimensional prompts of light and voice, and the function operation state and gear switching information are fed back in real time to improve the intuitiveness of human-computer interaction; the remote control of the mobile terminal supports customizing the fragrance release period, combined with the sound and light feedback on the device side to form a closed-loop control, optimizing the flexibility of the user's fragrance management and the environmental adaptation accuracy.

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Specific embodiments

[0036] The present invention will be further described below through specific embodiments.

[0037] See Figures 1 to 5 , a device with an aroma function, installed on a toilet, including an air pump 20, a foam module 30, an aroma module 40, a switching valve 50, a control module 60, etc. The device can be installed at a suitable position on the plate body 10 or the ceramic body 70 of the toilet. Taking the plate body 10 as an example, the plate body 10 is installed on the top of the ceramic body 70 of the toilet, and it is provided with a space for accommodating the air pump 20, the foam module 30, the aroma module 40, the switching valve 50 and the control module 60. The foam module 30 is used to mix the foaming liquid and gas to generate foam to achieve the foam function, and the foam outlet of the foam module 30 faces the toilet bowl 71 of the ceramic body 70 to output foam into the toilet bowl 71 of the ceramic body 70. The aroma module 40 is used to mix the liquid fragrance with air and spray out the fragrance to achieve the perfume spraying function, and the perfume spraying port of the aroma module 40 can face into the toilet bowl 71 or the outer periphery of the ceramic body 70. The air pump 20 is used to output pressurized gas. The input end of the switching valve 50 is connected to the output end of the air pump 20. The switching valve 50 has multiple output ends. One output end of the switching valve 50 is connected to the air inlet end of the foam module 30, and the other output end of the switching valve 50 is connected to the air inlet of the aroma module 40. The control module 60 is electrically connected to the air pump 20 and the switching valve 50 to control the air pump 20 to start outputting gas, and to control the switching valve 50 to switch to connect the foam module 30 to achieve the foam function, or to connect the aroma module 40 to achieve the perfume spraying function, or to switch to connect the foam module 30 and the aroma module 40 simultaneously.

[0038] The present invention realizes the air supply switching of the foam module 30 and the fragrance module 40 by a switching valve 50 with a single air pump 20, simplifies the pipeline structure and avoids gas interference between the two functions; integrates the foaming function and the fragrance spraying function into the internal space of the toilet. The foam generated by the foam module 30 can effectively cover the surface of the toilet bowl, playing a role in cleaning and preventing splashing. The fragrance sprayed by the fragrance module 40 can cover up the peculiar smell and create a fresh and comfortable usage environment, providing a more comfortable and pleasant usage experience for users. The control module 60 controls the action of the switching valve 50 through a set logic to ensure that the operations of foam generation and fragrance spraying do not conflict with each other, improving the coordination of the system operation. The overall structure realizes function expansion relying on the original toilet structure, having good adaptability and installation convenience.

[0039] Further, the fragrance module 40 includes a liquid storage chamber 41, a mixing chamber 42, a Venturi tube 43 and a liquid inlet tube 44. The liquid storage chamber 41 is used for storing liquid aromatic agents. The aromatic agents can be plant-derived essential oils, such as lavender essential oil, tea tree essential oil, etc.; or they can also be synthetic fragrances, such as artificial fragrances dissolved in ethanol / propylene glycol (air fresheners and detergents), concentrated fragrances (perfumes) with organic solvents such as benzyl alcohol as carriers, etc. The Venturi tube 43 is horizontally arranged. One end of the Venturi tube 43 serves as an air inlet and is connected to the output end of the switching valve 50 to introduce pressurized gas. The other end of the Venturi tube 43 serves as an air outlet and is communicated with the mixing chamber 42. One end of the liquid inlet tube 44 is communicated with the liquid storage chamber 41, and the other end is communicated with the Venturi tube 43 near the air outlet. The mixing chamber 42 is also provided with a fragrance spraying port 45. When the switching valve 50 conducts the air pump 20 and the fragrance module 40, when the pressurized gas flows through the Venturi tube 43, a high-speed air flow is formed due to the change in pipe diameter, generating a local negative pressure effect at the air outlet end of the Venturi tube 43, thereby sucking the aromatic agent in the liquid storage chamber 41 into the air outlet end of the Venturi tube 43 through the liquid inlet tube 44. The accelerated gas carries the aromatic agent droplets into the mixing chamber 42, where the gas-liquid two-phase mixing and dispersion are completed, and finally an aroma rich in fragrance components is formed and sprayed out through the fragrance spraying port 45. This structure utilizes the Venturi effect to realize the self-priming supply of the aromatic agent, without the need to additionally set a liquid pumping device, simplifying the structural complexity of the fragrance module 40. In practical applications, the fragrance module 40 can also adopt other similar structures and is not limited thereto.

[0040] In practical applications, the fragrance module 40 can be an integrally formed structure or a split structure. Taking the split structure as an example, it is provided with a main body 47 and an upper cover 48. The main body 47 is provided with a liquid storage cavity 41, and the top of the main body 47 is open for adding fragrance agents. The upper cover 48 is detachably fitted with the top opening of the main body 47, for example, by means of a threaded fit or a snap fit, etc. The upper cover 48 is provided with a mixing cavity 42, a Venturi tube 43, a liquid inlet pipe 44, and a fragrance spraying port 45. The liquid inlet pipe 44 extends into the liquid storage cavity 41, and the length of the liquid inlet pipe 44 can be set according to the size of the liquid storage cavity 41 to ensure smooth liquid suction under negative pressure. For example, the liquid inlet pipe 44 can extend to the bottom of the liquid storage cavity 41. The fragrance spraying port 45 can also be connected with a fragrance spraying pipe 46, and the fragrance spraying pipe 46 is provided to guide the fragrance to a set position. The air outlet end of the fragrance spraying pipe 46 can be located at the front side, or the rear side, or the left side, or the right side, or the middle of the bottom plate of the plate body 10, which is set according to requirements.

[0041] In the present invention, the foam module 30 can be implemented by using an existing foam structure. For example, the foam module 30 can be designed based on the Venturi effect or the principle of a variable-diameter channel, and the foaming function is realized through air flow power. Its core structure includes a tapered air inlet channel and a narrow throat section. When high-speed air flows through the throat, a negative pressure is formed, automatically sucking in the foaming liquid and preliminarily mixing it with the gas. Subsequently, in the gradually expanding diffusion section, the gas-liquid two-phase flow passes through turbulent disturbances and is fully refined and fused to form dense foam. A flat nozzle is configured at the end of the module for discharging the foam. The whole process only relies on fluid power to complete the gas-liquid mixing and foaming, with a simple structure and high operating efficiency. In practical applications, other foam modules 30 can also be used.

[0042] The plate body 10 includes a bottom plate 11 and a cover body 12, and a space for accommodating modules such as an air pump 20, a foam module 30, a fragrance module 40, a switching valve 50, and a control module 60 is formed between the bottom plate 11 and the cover body 12. The fragrance module 40 is close to the front side, or the rear side, or the left side, or the right side, or the middle of the bottom plate 11. The cover body 12 is fixed to the bottom plate 11 and an opening 13 is provided at the location where the fragrance module 40 is located. The number of openings 13 on the cover body 12 corresponds to the number of fragrance modules 40. In practical applications, an opening 13 can also be provided at the location where the foam module 30 is located on the cover body 12 to facilitate the replenishment or replacement of the foaming liquid of the foam module 30. A detachable closure is provided at the opening 13 on the cover body 12, and the closure is used to close the opening 13. Or a flip plate that can be opened and closed can also be provided near the fragrance module 40 on the cover body 12, and the fragrance agent of the fragrance module 40 can be replenished or the module can be replaced by opening the flip plate. The opening 13 provided on the cover body 12 enables the replenishment of the fragrance agent or the replacement of the module of the fragrance module 40 without disassembling the overall cover body 12, significantly improving the maintenance convenience. For example Figure 5 the cover body 12 can be provided with openings 13 at two different positions (front side or rear side), corresponding to the positions of the foam module 30 and the fragrance module 40 respectively.

[0043] For the device of the present invention, the switching valve 50 can be a three-way solenoid valve, a four-way solenoid valve or others, which can be set according to actual needs. For example, if it is necessary to realize the switching of the fragrance function or the foam function, only one switching valve 50 is required. If it is necessary to realize both the fragrance function and the foam function simultaneously, two switching valves 50 can be used. One switching valve 50 is connected to the fragrance module 40 and the air pump 20, and the other switching valve 50 is connected to the foam module 30 and the air pump 20. The number of fragrance modules 40 can be one or more. By replacing or adding switching valves 50, different fragrance modules 40 can be switched on to meet different fragrance requirements. See Figure 6 . The device of the present invention is installed on the plate body 10 of the toilet, and the timing of starting the foam function and the fragrance spraying function can be set according to needs. For example, when the user approaches the toilet, the foam function is started first, and then the fragrance spraying function is started, or the fragrance spraying function is started first, and then the foam function is started to realize the pre-purification of the air before using the toilet. During the user's use of the toilet, the fragrance spraying function is started at intervals to maintain the freshness of the air. After the user leaves the toilet, the foam function is started and the fragrance spraying function is turned off, etc.

[0044] In practical applications, the control module 60 of the device of the present invention can also be set to receive control commands from an external terminal (such as a mobile phone), and set customized time periods to turn on the fragrance spraying, switch the fragrance type according to personal preferences, etc., to increase the interactivity between the user and the product and enhance the sense of participation while experiencing the "odorless" toilet space.

[0045] Based on this, the present invention also proposes a fragrance control method for a toilet, which is realized by using a toilet with a fragrance module. The toilet can also detect whether the user is approaching or leaving, whether the cover plate is opened, whether the user is seated, etc. The toilet can be a smart toilet and also has functions such as automatic cover opening and cleaning. The cleaning function can include functions such as buttock washing, feminine washing and drying. The toilet can be a conventional ordinary toilet without automatic cover opening and cleaning functions. The toilet can also be a toilet with a device having the above-mentioned fragrance function.

[0046] The method of the present invention can also be set to multiple gears according to the duration of the fragrance spraying function. See Figure 7 , and the specific fragrance control method is as follows:

[0047] S1 When the toilet detects that the user is about to use the toilet, it controls the start of the fragrance spraying function of the fragrance module 40.

[0048] The plate body 10 of the present invention is connected with a cover plate, and the cover plate is rotatably connected to the plate body 10. See Figure 8When the toilet detects that the user is approaching or the toilet detects that the toilet lid changes from closed to open, it is determined that the user is about to use the toilet, and thus the fragrance spraying function is activated. It continues for a set time length or until the user sits down, and then the control stops the fragrance spraying function. When it detects that the user has sat down, the foam function is first activated. After a period of time, the control activates the fragrance spraying function and enters the first gear. The interval time can be set according to requirements, such as 30s, 40s, 1 minute, 2 minutes, etc.

[0049] In this step, after it is determined that the user is going to use the toilet, it is set to first activate the foam function to cover a layer of isolation layer on the surface of the toilet bowl, effectively reducing the attachment of dirt and the diffusion of odors. Then the fragrance spraying function is activated to create a fresh and comfortable use environment. The duration of the fragrance spraying function can be preset. After the duration reaches, the fragrance spraying function is automatically closed, or when it detects that the user has sat down, the fragrance spraying function is closed.

[0050] In the present invention, in the first gear, the fragrance spraying function operates in a first periodic cycle mode. In each cycle period, the fragrance spraying lasts for t1 seconds, and then the fragrance spraying stops for t2 seconds. The specific values of t1 and t2 can be several seconds and are set according to requirements. For example, t1 is 5s and t2 is 10s.

[0051] S2 When the toilet detects that the user is using the toilet, it controls the fragrance module 40 to execute the fragrance spraying function in different gears according to the usage situation.

[0052] Specifically, the fragrance spraying function also includes a second gear and a third gear. In the second gear, the fragrance spraying function operates in a second periodic cycle mode. In each cycle period, the fragrance spraying lasts for t3 seconds, and then the fragrance spraying stops for t4 seconds. The fragrance spraying function also includes a third gear. In the third gear, the fragrance spraying function operates in a third periodic cycle mode. In each cycle period, the fragrance spraying lasts for t5 seconds, and then the fragrance spraying stops for t6 seconds. The values of t3, t4, t5, and t6 can be set according to actual requirements. For example, t3 is 5, t4 is 5, t5 is 10, t6 is 5, etc. In actual applications, the fragrance spraying function can also be set with more gears, not limited to this.

[0053] In this step, refer to Figure 9 When the toilet detects that the user is using the cleaning function, it controls the fragrance spraying function to enter the second gear, and when the cleaning function ends, it controls the fragrance spraying function to enter the first gear. Refer to Figure 10 When the toilet detects that the user is using the drying function, it controls the fragrance spraying function to enter the third gear, and when the drying function ends, it controls the fragrance spraying function to enter the first gear. The duration of the fragrance spraying function in the third gear is set to be longer than that in the second gear to cooperate with deodorization and visually improve the deodorization effect.

[0054] By intelligently perceiving the user's functional requirements, the fragrance spraying gear is dynamically adjusted to adapt to different usage scenarios. When the cleaning or drying function is started, the fragrance release intensity is automatically increased to offset in real time the peculiar smell that may be caused by water vapor or air flow; after the function ends, the basic fragrance coverage is restored to maintain a fresh environment. This logic enables the fragrance intensity to be linked in real time with the changes in the spatial environment, avoiding waste caused by a single concentration, ensuring seamless connection of the odor experience at each stage, and simplifying the user operation through the function association trigger mechanism, taking into account both environmental comfort and resource utilization efficiency.

[0055] When the S3 toilet detects that the user has finished using it, it controls the fragrance spraying function of the fragrance module 40 to close.

[0056] In this step, it can be determined that the user has finished using it by detecting that the user leaves the toilet, closes the cover plate, or gets up from the seat, etc.

[0057] In the present invention, for an intelligent toilet with a cleaning function and a drying function, when the user defecates, steps S1 - S3 are executed; when a lady urinates or a man urinates, steps S1 and S3 are executed; for a common toilet without an automatic opening and cleaning function, when the user defecates or urinates, steps S1 and S3 are executed.

[0058] In the present invention, the toilet is further provided with a fragrance indicator light and a voice module on the cover plate device. When the fragrance spraying function is turned on, the fragrance indicator light lights up or flashes and the voice module broadcasts the set sound effect. When changing the gear, there will be a prompt sound. The color of the fragrance indicator light corresponds to different gears of the fragrance spraying function. For example, the first gear is yellow, the second gear is green, and the third gear is purple, but it is not limited to this. The control module 60 can also receive control commands from other mobile terminals to set the opening time and closing time of the fragrance spraying function, etc.
