Description

Technical Field

[0001] This utility model relates to the field of toilet technology, and in particular to an intelligent toilet drying and deodorizing integrated device. Background Technology

[0002] Currently, most smart toilets are equipped with drying and deodorizing functions. The drying function is typically achieved by a fan drawing in air, which is then heated by a heater and delivered to the user. The deodorizing function is also achieved by a fan drawing in air, which is then deodorized by a deodorizing medium before being expelled. However, the existing drying and deodorizing devices are usually separate units, requiring two air ducts and two fans. This results in higher costs and larger space requirements, hindering the design of thinner toilet seats. Utility Model Content

[0003] The present invention aims to provide an intelligent toilet drying and deodorizing integrated device, which can effectively reduce costs, reduce size, and has reliable function.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The intelligent toilet drying and deodorizing all-in-one device includes: The housing has an inner cavity that forms an air duct, which connects the front opening and the rear opening of the housing. The top wall of the housing is provided with a ventilation opening that communicates with the air duct. A fan is located inside the housing, and the fan is a bidirectional fan whose blades can rotate in both forward and reverse directions; A deodorization module, located inside the housing, is used to deodorize the gas passing through the deodorization module; A heating module, located inside the housing, is used to heat the gas passing through the heating module; The first baffle is rotatably mounted on the top wall of the housing to open and close the ventilation opening; The deodorization module, fan, and heating module are housed within the casing. The deodorization module is located behind the vent, while the fan and heating module are located in front of the vent. When the fan blades rotate clockwise, the first baffle is in a downward position under its own weight to open the vent, and the airflow direction in the duct is from back to front. When the fan blades rotate counterclockwise, the first baffle is in a rising position under the action of the wind in the duct to close the vent, and the airflow direction in the duct is from front to back.

[0005] In a preferred embodiment, the bottom wall of the housing is provided with a slope that slopes downward from back to front corresponding to the position of the vent, the deodorization module is located on the rear side of the slope, and the fan is located on the front side of the slope.

[0006] In a preferred embodiment, the inclination angle between the inclined surface and the bottom wall of the housing is 115°-135°.

[0007] In a preferred embodiment, the heating module is located on the front side of the fan.

[0008] In a preferred embodiment, a second baffle is further included. The second baffle is rotatably disposed on the top wall of the housing and located on the rear side of the deodorization module to open and close the rear opening. When the blades of the fan rotate clockwise, the second baffle is in a falling position under its own weight to close the rear opening; when the blades of the fan rotate counterclockwise, the second baffle is in a rising position under the action of the wind force in the air duct to open the rear opening.

[0009] In a preferred embodiment, when the first baffle is in the falling position, a flow passage is formed between the bottom end of the first baffle and the bottom wall of the housing. The flow passage cross-sectional area of ​​the flow passage, the flow passage cross-sectional area of ​​the vent, and the flow passage cross-sectional area of ​​the rear opening of the housing are all greater than the flow passage cross-sectional area of ​​the front opening of the housing.

[0010] In a preferred embodiment, one end of the first baffle is provided with a hinge portion and the other end is provided with a bending portion. The first baffle is hinged to the housing through the hinge portion. When the first baffle closes the vent, the bending portion fits against the edge of the vent.

[0011] In a preferred embodiment, the deodorization module includes an adsorption unit and a negative ion generator. The adsorption unit uses activated carbon or diatomaceous earth, and the negative ion generator is located behind the adsorption unit.

[0012] By adopting the above technical solution, this utility model can achieve at least the following technical effects: This invention integrates a deodorizing module, a fan, and a heating module within a single housing by using a bidirectional fan capable of both forward and reverse rotation. A vent connected to an air duct is located on the top wall of the housing. A first baffle opens and closes this vent. When the fan blades rotate forward, the first baffle, under its own weight, falls to open the vent on the top wall of the housing, allowing airflow from back to front within the duct for drying. When the fan blades rotate in reverse, the first baffle rises to close the vent, allowing airflow from front to back for deodorization. This invention integrates the existing toilet drying and deodorizing devices into a single unit, requiring only a housing and a fan, effectively reducing costs and the overall size of the device.

[0013] Furthermore, this invention further provides a downward-sloping surface on the bottom wall of the housing corresponding to the vent, with the deodorization module located on the rear side of the slope and the fan located on the front side of the slope. Under the action of the slope, the same wind force can exert a greater force on the first baffle. Especially in the deodorization state, the gas drawn in by the fan will flow from front to back. When the gas passes through the slope, it flows upward along the slope, thereby pushing the first baffle upward until the first baffle closes the vent, thus making the closing action of the first baffle more reliable.

[0014] In addition, by setting a second baffle, when the fan blades rotate forward, the second baffle can close the rear opening of the housing. In this way, outside air can only enter the air duct through the ventilation port, and then pass forward through the heating module to be heated and used to dry the human body. At this time, the air will not pass through the deodorization module, which effectively reduces the consumption of the deodorization module and can improve the service life of the deodorization module.

The terms “first,” “second,” etc., are only used to distinguish different objects and should not be construed as indicating or implying relative importance or the quantity, specific order, or primary or secondary relationship of the indicated technical features.

[0020] First embodiment: Combination Figures 1 to 5The first preferred embodiment of this utility model provides an integrated intelligent toilet drying and deodorizing device, which is installed inside the cover assembly (not shown) of an intelligent toilet and includes components such as a housing 1, a fan 2, a deodorizing module 3, a heating module 4, and a first baffle 5, wherein: The inner cavity of the housing 1 forms an air duct 11, which passes through the front opening 12 and the rear opening 13 of the housing 1. The front opening 12 faces the inner cavity of the toilet bowl (not shown). The top wall of the housing 1 is provided with a vent 14 that communicates with the air duct 11. The fan 2 is located inside the casing 1. The fan 2 is a bidirectional fan 2 with blades 21 capable of rotating forward and backward. The deodorization module 3 is located inside the housing 1 and is used to deodorize the gas passing through the deodorization module 3; Heating module 4 is located inside housing 1 and is used to heat the gas passing through heating module 4; The first baffle 5 is rotatably mounted on the top wall of the housing 1 to open and close the ventilation opening 14; The deodorizing module 3, fan 2, and heating module 4 are installed inside the housing 1. The deodorizing module 3 is located behind the vent 14, and the fan 2 and heating module 4 are located in front of the vent 14. When the blades 21 of the fan 2 rotate clockwise, the first baffle 5 is in a downward position under its own weight to open the vent 14. The airflow direction of the air duct 11 is from back to front. After being heated by the heating module 4, the gas flows out from the front opening 12 of the housing 1 to dry the buttocks of the human body, thus achieving the drying function. When the blades 21 of the fan 2 rotate counterclockwise, the first baffle 5 rotates upward to the rising position under the action of the wind in the air duct 11 to close the vent 14. The airflow direction of the air duct 11 is from front to back. The odor in the toilet bowl enters the air duct 11 from the front opening 12 of the housing 1, is deodorized by the deodorizing module 3, and then flows out from the rear opening 13, thus achieving the deodorizing function.

[0021] By incorporating a bidirectional fan 2 capable of both forward and reverse rotation, the deodorization module 3, fan 2, and heating module 4 are all housed within the same casing 1. A vent 14, connected to an air duct 11, is located on the top wall of the casing 1. A first baffle 5 opens and closes this vent 14. When the blades 21 of the fan 2 rotate forward, the first baffle 5, under its own weight, falls to open the vent 14 on the top wall of the casing 1, allowing airflow from the back of the air duct 11 to the front, thus achieving the drying function. When the blades 21 of the fan 2 rotate in reverse, the first baffle 5, under the influence of the airflow in the air duct 11, rises to close the vent 14, allowing airflow from the front of the air duct 11 to the back, thus achieving the deodorization function. This invention integrates the existing toilet drying and deodorization devices into one unit, requiring only a casing 1 and a fan 2, effectively reducing costs and the overall size of the device.

[0022] In this embodiment, preferably, the bottom wall of the housing 1 has a downward sloping surface 15 at the position corresponding to the vent 14. The deodorization module 3 is located on the rear side of the sloping surface 15, and the fan 2 is located on the front side of the sloping surface 15. Under the action of the sloping surface 15, the same wind force can exert a greater force on the first baffle 5. Especially in the deodorization state, the gas drawn in by the fan 2 will flow from front to back. When the gas passes through the sloping surface 15, it flows upward along the sloping surface 15, thereby pushing the first baffle 5 upward until the first baffle 5 closes the vent 14, thus making the closing action of the first baffle 5 more reliable.

[0023] In this embodiment, the inclination angle α between the inclined surface 15 and the bottom wall of the housing 1 is 115°-135°. Within this angle range, the inclined surface 15 can more effectively guide the airflow upward to push the first baffle 5, so that the first baffle 5 rotates upward to the rising position to close the vent 14.

[0024] In this embodiment, the heating module 4 is specifically located on the front side of the fan 2. Of course, the heating module 4 can also be located on the rear side of the fan 2, and the positions of the two can be interchanged.

[0025] In this embodiment, when the first baffle 5 is in the falling position, a flow port 6 is formed between the bottom end of the first baffle 5 and the bottom wall of the housing 1. The flow cross-sectional area of ​​the flow port 6, the flow cross-sectional area of ​​the vent 14, and the flow cross-sectional area of ​​the rear opening 13 of the housing 1 are all larger than the flow cross-sectional area of ​​the front opening 12 of the housing 1. This design ensures that sufficient airflow is provided for drying the human body.

[0026] In this embodiment, the first baffle 5 has a hinge portion 51 at one end and a bending portion 52 at the other end. The first baffle 5 is hinged to the housing 1 through the hinge portion 51. When the first baffle 5 closes the vent 14, the bending portion 52 fits against the edge of the vent 14. The fit between the bending portion 52 and the edge of the vent 14 allows the vent 14 to be closed more tightly, preventing a small portion of gas from leaking out through the gap between the first baffle 5 and the edge of the vent 14 without deodorization, resulting in better deodorization. The hinge portion 51 is specifically a rotating shaft. The top of the side wall of the housing 1 has a shaft hole 16. The rotating shaft fits into the shaft hole 16, allowing the first baffle 5 to be rotatably mounted on the housing 1.

[0027] In this embodiment, the deodorization module 3 includes an adsorption unit 31 and a negative ion generator 32. The adsorption unit 31 can be made of activated carbon or diatomaceous earth, etc., to deodorize odors through physical adsorption. The negative ion generator 32 is located behind the adsorption unit 31 and deodorizes odors through negative ions, further improving the deodorization effect.

[0028] The heating module 4 can use an existing structure, such as a heating wire.

[0029] Second embodiment: Combination Figure 6 and Figure 7 The second preferred embodiment of this utility model provides an intelligent toilet drying and deodorizing integrated device. The difference between this device and the first embodiment is that it further includes a second baffle 7. The second baffle 7 is rotatably mounted on the top wall of the housing 1 and located behind the deodorizing module 3 to open and close the rear end opening 13 of the housing 1. When the blades of the fan 2 rotate clockwise, the second baffle 7 is in a downward position under its own weight to close the rear end opening 13 of the housing 1; when the blades of the fan 2 rotate counterclockwise, the second baffle 7 is in a rising position under the action of the airflow in the air duct 11 to open the rear end opening 13. The advantage of setting the second baffle 7 is that when the blades of the fan 2 rotate clockwise, the second baffle 7 can close the rear end opening 13, so that outside air can only enter the air duct 11 through the vent 14, and then pass forward through the heating module 4 for heating and drying the human body. At this time, the air will not pass through the deodorizing module 3, effectively reducing the consumption of the deodorizing module 3 and improving its service life.

[0030] The remaining structure of this embodiment is the same as that of the first embodiment, and will not be described again here.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are within the protection scope of this utility model.
