[0023] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0024] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1-2As shown, an ultraviolet (UV) teacup sterilizer includes a support base 1 and a housing 2. The support base 1 is fixedly connected to the housing 2. The support base 1 is used to place the UV teacup sterilizer on a platform, thereby ensuring the UV teacup sterilizer is placed stably and improving the stability of the sterilization operation. The housing 2 has a teacup placement cavity 3 with open ends. During the sterilization operation, the teacup is placed into the teacup placement cavity 3. The open-end structure of the teacup placement cavity 3 improves the convenience of taking out the teacup, allowing it to be used immediately, and is both aesthetically pleasing and convenient.

[0027] A circuit board 4 and three sets of ultraviolet (UV) sterilization components are fixedly installed inside the outer casing 2. These UV sterilization components are electrically connected to the circuit board 4 and are distributed on the left and right side walls and top of the teacup placement cavity 3. The UV rays emitted by these components can irradiate the teacup placement cavity 3. Each UV sterilization component is equipped with an LED UV sterilization lamp 5. During sterilization, the circuit board 4 controls the UV sterilization components to operate, causing the LED UV sterilization lamps 5 to light up. The LED UV sterilization lamps 5 then emit UV rays that irradiate the teacup placement cavity 3, achieving the function of UV sterilization of the teacups inside. This UV teacup sterilizer uses LED UV sterilization lamps 5 as the UV light source, is mercury-free and more environmentally friendly, and is ready to use immediately without preheating, improving ease of use.

[0028] The bottom of the teacup placement cavity 3 is equipped with a rotatable cup holder 6 for placing teacups. A drive device is located inside the outer casing 2, electrically connected to the circuit board 4. The output of the drive device is connected to the cup holder 6, driving it to rotate within the teacup placement cavity 3. When using this ultraviolet teacup sterilizer, the teacup is placed on the cup holder 6 through the teacup placement cavity 3. The circuit board 4 then controls the drive device and the ultraviolet sterilization component. The LED ultraviolet sterilization lamp 5 illuminates, irradiating the teacup with ultraviolet light. Simultaneously, the drive device rotates the cup holder 6, causing the teacup to rotate 360°, thus achieving 360° sterilization without blind spots.

[0029] This ultraviolet teacup sterilizer solves the problem of incomplete sterilization in existing sterilization methods by setting ultraviolet sterilization components on both sides and top of the teacup placement cavity 3, and driving the cup holder 6 to rotate with a drive device. This achieves continuous and thorough ultraviolet irradiation of the teacup on the cup holder 6.

[0030] To ensure that the teacup can be placed stably on the cup holder 6, multiple anti-slip grooves 61 are provided on the upper surface of the cup body. By setting the anti-slip grooves 61, the teacup can be placed stably on the cup holder 6, preventing the teacup from shifting or falling during the rotation and sterilization process, thus improving the stability of the operation.

[0031] In order to enable the circuit board 4 to be installed and fixed inside the housing 2, a second snap-fit ​​groove 21 is provided inside the housing 2, and the circuit board 4 snaps into the second snap-fit ​​groove 21; the second snap-fit ​​groove 21 can install and fix the circuit board 4 inside the housing 2, thereby improving the stability of the structure.

[0032] The outer casing 2 is equipped with a sensor-activated component, which is electrically connected to the circuit board 4. The sensor-activated component is used to detect whether a teacup is placed in the cup holder 6. During use, when the user places the teacup on the cup holder 6, the sensor-activated component can detect the teacup on the cup holder 6 in a timely manner. Then, the sensor-activated component will send an activation signal to the circuit board 4, and the circuit board 4 will then control the drive device and the ultraviolet sterilization component to work, so as to realize the function of sterilizing the teacup.

[0033] Specifically, the induction start-up component includes an infrared sensor 7 disposed on the side wall of the teacup placement cavity 3. The infrared rays emitted by the infrared sensor 7 can penetrate into the teacup placement cavity 3. In actual operation, the infrared rays emitted by the infrared sensor 7 will illuminate the teacup placement cavity 3; after the teacup is placed on the cup holder 6, the teacup will block the infrared sensor 7, at which time the infrared sensor 7 will immediately send a start signal back to the circuit board 4.

[0034] In this embodiment, there are two sets of infrared sensors 7, located at the upper and lower ends of the teacup placement cavity 3, respectively. The simultaneous operation of both sets of infrared sensors 7 improves system stability and reduces the occurrence of false triggering. In other embodiments, the number of infrared sensors 7 can be any other number; additionally, in other embodiments, other types of sensors can be used instead of infrared sensors 7; for example, a pressure sensor can be installed on the cup holder 6.

[0035] In this embodiment, a delay module and a timing module are integrated on the circuit board 4. In specific operation, after the induction start component sends the start signal to the circuit board 4, the delay module on the circuit board 4 will automatically delay for 10 seconds before controlling the drive device and the ultraviolet disinfection component to work. After that, the timing module on the circuit board 4 will send a stop working signal to the drive device and the ultraviolet disinfection component after they have worked for 60 seconds, thereby controlling the drive device and the ultraviolet disinfection component to stop working.

[0036] The ultraviolet disinfection component includes a lamp board 8, which is electrically connected to the circuit board 4. Each lamp board 8 has three LED ultraviolet disinfection lamps 5 evenly distributed on it. In other embodiments, any number of other LED ultraviolet disinfection lamps 5 can also be provided on the lamp board 8.

[0037] To facilitate the fixing of the lamp panel 8, a fixing bracket 9 is provided at a corresponding position inside the outer casing 2 corresponding to the ultraviolet disinfection component. The lamp panel 8 is fixedly installed on the corresponding fixing bracket 9, and the fixing bracket 9 can fix the lamp panel 8 inside the outer casing 2. Specifically, the fixing bracket 9 is provided with a first snap-fit ​​groove 91, and the lamp panel 8 is snapped into the corresponding fixing bracket 9 via the first snap-fit ​​groove 91. The lamp panel 8 is installed and fixed on the fixing bracket 9 through the first snap-fit ​​groove 91, thereby improving the stability of its structure.

[0038] To reduce the amount of ultraviolet light emitted by the LED ultraviolet disinfection lamp 5 that shines onto the exterior of the outer casing 2, a light-shielding plate 10 is installed on the mounting bracket 9. The light-shielding plate 10 is located on both the front and rear sides of the LED ultraviolet disinfection lamp 5, limiting the irradiation area of ​​the LED ultraviolet disinfection lamp 5. During operation, most of the ultraviolet light emitted by the LED ultraviolet disinfection lamp 5 will irradiate the teacup placement cavity 3 to disinfect the teacup. A small portion of the ultraviolet light will be emitted towards the exterior of the outer casing 2, irradiating the light-shielding plate 10. The light-shielding plate 10 will absorb this small portion of ultraviolet light, preventing it from reaching the exterior of the outer casing 2 and thus preventing harm to the human body. By installing light-shielding plates 10 on both the front and rear sides of the LED ultraviolet disinfection lamp 5, the safety of the ultraviolet teacup sterilizer during disinfection is improved.

[0039] The driving device includes a drive motor 11, which is fixedly mounted on the housing 2 and electrically connected to the circuit board 4. The output end of the drive motor 11 is fixedly connected to the cup holder 6. During disinfection, the drive motor 11 drives the cup holder 6 to rotate, thereby achieving 360° disinfection without dead angles. In other embodiments, the driving device may also employ other devices or structures capable of rotational drive, and this invention does not limit such applications.

[0040] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
