TECHNICAL FIELD

[0001] The present application relates to the technical field of smart home, and in particular to a sterilization toilet. BACKGROUND

[0002] Toilet is an essential daily necessity in people's life, but there are also many bacteria on the toilet that can affect human health. Currently, the ultraviolet light sterilization in the inner cavity of the toilet on the market generally installs the light source device on the toilet cover. This installation method has great difficulty in manufacturing the cover plate and increases the thickness of the cover plate because the wiring needs to pass through the cover plate reel. Moreover, the UVC-LED light efficiency on the market is extremely low, and the heat generation is very large. Only about 2% of the input electric power is converted into ultraviolet light, and the remaining about 98% of the electric power is converted into heat. The heat reduces the light output of the UVC-LED and seriously shortens the service life. How to achieve heat dissipation in a small volume has always been a difficult problem in the industry.

[0030] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0031] Ultraviolet light has strong destructive power on the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) of bacteria and viruses, can make bacteria and viruses lose viability and reproductive capacity, on the one hand, can cause nucleic acid mutation, hinder replication, transcription block and protein synthesis, on the other hand, can produce free radicals to cause photoionization, thereby causing cell death, and then eliminating bacteria and viruses, which can effectively disinfect and sterilize.

[0032] UVC-LED is a kind of LED, the wavelength range is: 10-400nm.

[0033] As shown in Figure 1 The present application provides a sterilization toilet, which comprises a toilet base 1 and a toilet cover 2 hingedly arranged on the toilet base 1; the toilet base 1 is provided with a first cavity 3 formed by the inner wall of the toilet and opening upward; a sterilization device 6 is arranged on the inner wall of the toilet, the sterilization device 6 is connected with a control device 7, the control device 7 is used for providing electric energy for the sterilization device 6, the sterilization device 6 sterilizes the toilet and utilizes the circulating water in the toilet. Especially, the first cavity 3 is comprehensively sterilized, and the waterway for flushing the first cavity 3 of the toilet itself is utilized for temperature reduction.

[0034] It can be understood that the above-mentioned toilet can be a common toilet, only a sterilization device 6 and a control device 7 need to be added, and the control device 7 can be arranged at any position of the toilet which does not contact with water.

[0035] In one embodiment of the present invention, the toilet is a smart toilet, i.e., equipped with a rotary spraying device. A rotary spraying device 4 is provided on the side of the toilet lid 2 facing the first cavity 3. The rotary spraying device 4 includes a spraying rod 5 with a nozzle. A sterilizing device 6 is provided on the inner wall of the toilet bowl, below the height of the spraying rod 5. The sterilizing device 6 is connected to a control device 7 and sterilizes the toilet bowl while cooling it using circulating water within the toilet bowl and / or water from the spraying rod.

[0036] It can be understood that when the internal circulating water of the toilet is used for cooling, the sterilization device 6 only needs to be set on the internal circulating water circulation path; when the water of the spray rod is used for cooling, the water path of the sterilization device 6 is connected with the water path of the spray rod, that is, the water of the spray rod must enter the sterilization device and then flow out and be discharged into the drain of the first cavity 3.

[0037] The sterilization device of the present invention is arranged on the inner wall of the toilet, and there is no need to modify the toilet cover. The water channel of the toilet itself can be used to achieve module heat dissipation, and the design is exquisite.

[0038] Furthermore, the sterilization device of the present invention is a UVC-LED sterilization device. Because the unique setting position of the present invention makes the sterilization device have good heat dissipation performance, the sterilization efficiency and service life of the sterilization device are improved.

[0039] In one embodiment of the present invention, the control device 7 includes a drive device, which includes a rotary motor and a spray rod motor. The rotary motor can drive the spray rod to rotate axially about a plane perpendicular to the cover plate, and the spray rod motor can drive the spray rod to rotate on its own. The control device 7 also includes a circuit for switching the sterilization device 6 on and off and controlling the irradiation duration. It is understood that the sterilizing toilet of the present invention also includes a distance sensor and a human body sensing sensor, which are arranged on the inner wall of the toilet cover 2 and connected to the control device 7. The distance sensor is used to detect when the toilet cover 2 is closed to the toilet base and provide feedback to the control device 7, so that the control device 7 can power on the sterilization device 6 for sterilization. The human body sensing sensor is used to detect a human body and provide feedback to the control device 7, so that the control device 7 can power off the sterilization device 6 to stop sterilization.

[0040] In a more preferred embodiment, the cross-section of the first cavity 3 is elliptical, with the sterilization device 6 positioned at the vertex of the ellipse, closest to the water tank. It will be appreciated that the sterilization device 6 is positioned on the inner wall of the toilet bowl directly below the spray bar 5. This arrangement allows for the spray bar's self-cleaning water flow to be used for cooling, while also ensuring that the emitted ultraviolet light forms a spot to maximize coverage of the first cavity.

[0041] like Figure 2 As shown, the sterilization device 6 includes, in order: an upper cover 8, a transparent window 10, a UVC-LED sterilization light source 11, and a metal base;

[0042] A first sealing ring 9 is provided between the upper cover 8 and the transparent window 10; a sealing ring 12 is provided between the transparent window 10 and the metal base for encapsulating the UVC-LED sterilization light source 11; the pins of the UVC-LED sterilization light source pass through the metal base and are connected to the control device.

[0043] As shown in FIG3(a) and FIG3(b), in one embodiment of the present invention, the metal base is integrally formed, and the metal base is annular and includes: a first shell 19, a second shell 20, a third shell 21 and a fourth shell 22.

[0044] The first housing 19 and the second housing 20 form an annular structure, and the third housing 21 and the fourth housing 22 are used to encapsulate the first housing 19 and the second housing 20 to form a closed annular structure;

[0045] The first shell 19 is provided with a water outlet 14 and a water inlet 18 to form a water circulation in the closed annular structure. The water inlet 14 is connected to the water pipe of the self-cleaning water circuit of the spray rod, and the water outlet 18 discharges water directly into the drain of the toilet cavity.

[0046] First, the flow of water in the toilet removes the heat generated by the sterilization device, cooling the metal base and, in turn, the sterilization device. Simultaneously, the self-cleaning water path within the toilet cools the metal base, further cooling the sterilization device. This achieves a cooling effect while being energy-efficient and environmentally friendly.

[0047] like Figure 4 The figure shows a schematic diagram of the water circulation of the metal base. The water circuit here is connected to the water pipe of the self-cleaning water circuit of the spray rod through the water inlet 14, and the water outlet 18 discharges the water directly into the drain of the toilet cavity.

[0048] like Figure 5 The figure shows a schematic diagram of a sterilization device. In the figure, it can be seen that a water circuit is set inside the metal base to cool the sterilization device.

[0049] In one embodiment of the present invention, the metal base is made of aluminum or an aluminum alloy, copper, or stainless steel. The transparent window is made of any material selected from the group consisting of double-polished sapphire, quartz, silicon, glass, plastic, resin, and silicone. Any substantially completely transparent dielectric material is sufficient, particularly quartz and silicone. The specific structure of the transparent window can be designed using conventional optical design methods to ensure that the light beam from the light source is focused on the inner wall of the toilet bowl.

[0050] In order to further enhance the sterilization effect of the sterilization device, the third shell 21 is a metal base and a transparent window 10 encapsulated surface, and the third shell 21 is concave, which is used to condense the light beam emitted by the UVC-LED sterilization light source 11. It can be understood that the third shell 21 here plays a role similar to that of a reflector cup, and the degree of concave can be determined according to specific needs.

[0051] In an embodiment of the present application, the UVC-LED sterilization light source 11 includes a UVC-LED chip, a LED substrate with a reflecting device, a circuit board and a pin, the light emitted by the LED chip is reflected by the LED substrate once, and the light angle is about 70-90 degrees. Most of the light is emitted through the transparent window, and a small part of the light reflected by the transparent window is also emitted to the target sterilization area after being reflected twice by the third shell of the metal base. The emitted light projects an elliptical spot, which can cover the inner wall of the toilet, has a large irradiation area and a long irradiation distance, and achieves the purpose of sterilization.

[0052] Because the sterilization device 6 is arranged on the inner wall of the sterilization toilet, the waterproofness of the sterilization device 6 is very important, and the position where the pin of the UVC-LED sterilization light source in the fourth shell 22 is arranged is provided with a pit for pouring glue for waterproofing, and further waterproofing.

[0053] As shown in Figure 6 It can be understood that the upper cover 8, the transparent window 10, the UVC-LED sterilization light source 11 and the metal base are adaptively closely matched to form a closed waterproof arrangement.

[0054] As shown in FIG. 7(a) and FIG. 7(b), in another embodiment of the present application, in order to reduce the preparation cost, the metal base is not integrally formed. The metal base is in the form of a circular ring and includes a base body and a base pressing plate 16. The base body includes a first shell 19, a second shell 20 and a third shell 21. The first shell 19 and the second shell 20 form a ring structure, and the third shell 21 and the base pressing plate 16 are used to encapsulate the first shell 19 and the second shell 20 to form a closed ring structure.

[0055] The water inlet 14 and the water outlet 18 arranged on the first shell 19 form a water circulation in the closed ring structure.

[0056] Similarly, in order to ensure the sealing of the sterilization device, a sealing gasket 15 is arranged between the base body and the base pressing plate 16, and the base body and the base pressing plate 16 are fixedly connected, for example, can be riveted or connected through screws or bolts. The metal base can also be welded on the base body.

[0057] In an embodiment of the present application, the base pressing plate 16 is fixed on the base body by a screw 17.

[0058] As previously shown, to improve the sterilization effect of the sterilization device, the third housing 21 is concave to focus the light beam emitted by the UVC-LED germicidal light source 11. It is understood that the role of the third housing 21 here is similar to that of a reflective cup, and the degree of its concavity can be determined according to specific needs.

[0059] In one embodiment of the present invention, the sterilization device may be a sterilization device that generates ultraviolet rays and ozone, and / or a sterilization device that automatically and regularly generates ultraviolet rays and ozone at predetermined time intervals, which can further improve the sterilization effect.

[0060] like Figure 2 The figure shows a schematic diagram of a sterilization device according to the present invention. The device comprises an upper cover 8, a transparent window 10, a UVC-LED germicidal light source 11, and a metal base. A first sealing ring 9 is disposed between the upper cover 8 and the transparent window 10; a second sealing ring 12 is disposed between the transparent window 10 and the metal base, encapsulating the UVC-LED germicidal light source 11. The metal base comprises an annular structure formed by a base body 13 and a base pressure plate 16. A water inlet 14 and a water outlet 18 are disposed on the first outer shell of the base body 13. To enhance circulation, the water inlet 14 and the water outlet 18 are positioned relative to each other to maximize water circulation within the metal base. The base pressure plate 16 is secured to the base body 13 by screws 17. The pins of the UVC-LED germicidal light source 11 extend from the center of the annular structure of the metal base to connect to a control device.

[0061] like Figure 8 The figure shows a schematic diagram of a metal base according to the present invention. The third housing 21 is concave, forming a reflector cup. This eliminates the need for a reflector cup within the lamp itself, which would be costly. Furthermore, optical design can be tailored to the specific application scenario, resulting in improved results.

[0062] like Figure 9 The figure shows a schematic diagram of a sterilization device of the present invention. The upper cover 8, the transparent window 10, the UVC-LED sterilization light source 11, and the metal base are connected in sequence. The pins of the UVC-LED sterilization light source pass through the metal base and are connected to the control device. In a specific embodiment, the transparent window 10 is a silicone convex lens, which concentrates the light beam emitted by the UVC-LED sterilization light source 11 to the sterilization position for sufficient sterilization; it is understandable that it can be set accordingly with the third shell 21 so that the light beam reaches a longer distance and irradiates a larger area; the optimal situation is that the light beam can just cover the first cavity 3.
