Description

TECHNICAL FIELD

[0001] The utility model relates to chopsticks technical field, specifically, relate to a UV disinfection chopsticks. BACKGROUND

[0002] In the family environment, chopsticks are generally placed in the disinfection cage disinfection. Disinfection cage usually utilizes high temperature, ultraviolet or ozone etc. to kill the bacteria, virus and other harmful microorganism on the chopsticks surface. But disinfection cage is bulky, heavy, is inconvenient for people to carry, and often needs stable power supply or specific placement space when using, limits its application in the family environment outside scene.

[0003] For student party and office worker, they eat out more frequently, the health condition of public tableware is uneven, and using self-provided chopsticks can guarantee health, but there is lack of disinfection device for self-provided chopsticks under the public place environment, and students and office workers are difficult to effectively disinfect chopsticks before and after eating.

[0004] In addition, when people picnic or participate in other outdoor activities, the environment is relatively simple and far away from the family environment. At the same time, it is unrealistic to carry heavy disinfection cage, it will increase the burden of outdoor equipment, and seriously affect the travel experience.

[0005] Therefore, in view of the above-mentioned situation of chopsticks disinfection inconvenience, a new type of convenient chopsticks disinfection solution is urgently needed. This scheme should be small and light, and can kill harmful microorganisms on chopsticks efficiently, meet the health demand of people to chopsticks in different life scenes. CONTENT OF THE UTILITY MODEL

[0006] In view of the problem that the chopsticks are difficult to disinfect in the field environment in the prior art, the utility model provides a UV disinfection chopsticks.

[0007] In order to solve the above technical problem, the utility model solves the problem through the following technical scheme:

[0008] A kind of UV disinfection chopsticks, including main chopstick body and chopstick head, the main chopstick body inside is equipped with cavity, ultraviolet lamp and control system for controlling the switch of ultraviolet lamp are fixed in cavity;Chopstick head includes installation part and use part, installation part is detachably installed on main chopstick body, use part is fixed on the end face of installation part far from main chopstick body, and use part can be inserted into cavity and disinfect.

[0009] Addressing the issue of chopsticks easily becoming contaminated with pollutants and the lack of convenient disinfection methods when dining out, this design with a built-in ultraviolet lamp enables the chopsticks to disinfect themselves, eliminating the need to carry additional large disinfection equipment and solving the problem of inconvenient disinfection. Furthermore, the chopstick tip is inserted into the cavity for disinfection. On one hand, the outer wall of the tip directly receives the ultraviolet rays emitted by the lamp, resulting in better disinfection. On the other hand, it prevents the ultraviolet rays emitted by the lamp from spreading outwards during disinfection and causing harm to the user.

[0010] Preferably, a limiting ring is fixed in the middle of the outer side wall of the mounting part. When the sterilized chopsticks are in use, the mounting part is inserted into the cavity of the main chopstick body, and the upper end face of the limiting ring abuts against the lower end face of the main chopstick body. When the sterilized chopsticks are sterilized, the use part is inserted into the cavity, and the lower end face of the limiting ring abuts against the lower end face of the main chopstick body.

[0011] By setting the limiting ring, the positional relationship between the installation part and the user part and the main chopstick body is limited. On the one hand, it can avoid the problem that the installation part enters the cavity too deeply due to user misoperation, making it difficult to separate the main chopstick body from the chopstick tip. On the other hand, it can also avoid the problem that the user part enters the cavity too deeply during the disinfection operation, causing damage to components such as the ultraviolet lamp inside the cavity.

[0012] Preferably, the user part is a platform, and the area of ​​the end face of the user part near the mounting part is larger than the area of ​​the end face of the user part far from the mounting part.

[0013] The above settings ensure that the ultraviolet lamp can irradiate the side wall of the user section, thereby disinfecting the side wall of the user section and optimizing the disinfection effect of the ultraviolet lamp.

[0014] Preferably, both the cavity and the mounting part have rectangular cross-sections, and the sidewalls of the cavity have rounded corners at their edges, as do the corresponding sidewalls of the mounting part.

[0015] The rectangular cross-section design effectively prevents the mounting part from rotating relative to the cavity. This is because the relationship between the sides and corners of the rectangle provides significant limiting effect in all directions after installation, offering a more stable usage state for the chopsticks compared to circles or other shapes. The rounded corners of the cavity and mounting part's side walls are primarily for user safety and comfort. During use, the rounded corners prevent wear and tear caused by frequent contact between the right-angled edges of the side walls and the hand, improving the user experience.

[0016] Preferably, a baffle is provided inside the cavity, which divides the cavity into a disinfection chamber and an electrical installation chamber, and the user part can be inserted into the disinfection chamber for disinfection.

[0017] The cavity is partitioned by the baffle to realize functional partition; the sterilization area and the electrical appliance installation area are independent of each other, so that the water vapor and other substances attached to the chopsticks during sterilization do not damage the electrical appliance elements, and the normal operation and service life of the electrical appliance are ensured. Meanwhile, the above-mentioned arrangement helps to form a relatively independent and stable sterilization environment in the sterilization cavity, and improves the sterilization efficiency and quality.

[0018] Preferably, a mounting hole is formed in the center of the baffle, and the ultraviolet lamp is arranged in the mounting hole, and the outer wall of the ultraviolet lamp is attached to the inner wall of the mounting hole.

[0019] The mounting hole in the baffle provides a clear and stable mounting position for the ultraviolet lamp, and the ultraviolet lamp is reasonably arranged in the baffle space, so that the internal structure of the sterilization chopsticks is more compact and the stability of the sterilization chopsticks in the cavity is ensured. The ultraviolet lamp cooperates with the baffle to separate the sterilization cavity and the electrical appliance installation cavity.

[0020] Preferably, the control system comprises a control switch, and the control switch is arranged on the end face of the installation part of the electrical appliance installation cavity.

[0021] When the sterilization chopsticks are used, a user holds the side wall of the sterilization chopsticks. The above-mentioned arrangement facilitates the user to turn on or off the sterilization function, avoids accidental touch during use, and does not affect the normal holding and use of the chopsticks. This design meets the demand for outdoor convenient use, and makes the sterilization operation simple and easy.

[0022] Preferably, the control system further comprises an infrared ray emitting end and an infrared ray receiving end arranged on the inner wall of the cavity, the infrared ray receiving end can receive the infrared signal sent by the infrared ray emitting end, the lower end face of the limiting ring abuts against the lower end face of the main chopstick body, the use part extends between the infrared ray emitting end and the infrared ray receiving end, and the circuit in which the infrared ray emitting end and the infrared ray receiving end are arranged is connected to the circuit in which the control switch is arranged by using an AND gate logic.

[0023] Under normal conditions, the infrared ray receiving end continuously receives the infrared signal emitted by the infrared ray emitting end, so that the circuit in which the ultraviolet lamp is arranged is in an open circuit state; during sterilization, the use part extends between the infrared ray emitting end and the infrared ray receiving end, so that the infrared ray receiving end cannot receive the signal, and the ultraviolet lamp can be turned on by pressing the control switch at this time. The above-mentioned arrangement can ensure that the control switch can be pressed to turn on the ultraviolet lamp only when the use part is accurately inserted into the specified position, and can effectively avoid the problem that the ultraviolet light emitted by the ultraviolet lamp leaks outward due to accidental touch of the control switch by the user during use of the sterilization chopsticks.

[0024] Preferably, a charging port is arranged in the cavity, a through hole for inserting a charging wire is arranged on the side wall of the main chopstick body, and a waterproof silica gel plug is arranged at the through hole.

[0025] The charging port is convenient for charging the disinfection chopsticks, so as to ensure the continuous disinfection ability in multiple picnic uses. The design of the through hole and the waterproof silica gel plug meets the charging demand and prevents water, dust and the like from entering in the outdoor environment, so as to ensure the safety of charging and the stability of the equipment in the complex outdoor environment.

[0026] As preferred, the inside of the electric appliance installation cavity is provided with an indicating lamp, and the sidewall of the main chopstick body is provided with a transparent window matched with the indicating lamp.

[0027] The indicating lamp can intuitively display the disinfection state. The user can know whether the chopsticks are disinfected without complex operation, so as to quickly judge whether the chopsticks can be safely used in the picnic process, and the convenience of use is improved.

DETAILED DESCRIPTION

[0036] In order to further understand the content of the present application, the present application is described in detail in combination with the drawings and the embodiments. It should be understood that the embodiments are only used to explain the present application but not to limit the present application.

[0037] EMBODIMENT

[0038] This embodiment discloses a UV-sterilized chopsticks, such as Figures 1-5 As shown, it includes a main chopstick body 110 and chopstick tips 120. The lower end face of the main chopstick body 110 is provided with a cavity. A baffle 190 is provided in the cavity, which divides the cavity into a disinfection chamber 1801 and an electrical appliance mounting chamber 1802. A mounting hole is provided at the center of the baffle 190, and an ultraviolet lamp 1102 is fixed in the mounting hole. The ultraviolet lamp 1102 is in contact with the inner wall of the mounting hole. A control system for controlling the switch of the ultraviolet lamp 1102 is installed in the electrical appliance mounting chamber 1802.

[0039] like Figure 6 As shown, this embodiment provides a principle block diagram of a disinfection chopsticks control system. The content shown in this block diagram does not constitute a limitation on the only implementation method of the disinfection chopsticks control system. Those skilled in the art, when applying the core inventive points of this patent, can reasonably improve and optimize the system according to specific production process conditions, usage environment requirements, and different technology combinations. All such modifications fall within the scope of protection of this patent. The power supply 170 can provide two different circuit voltages for the ultraviolet lamp 1102, enabling the ultraviolet lamp 1102 to emit two different ultraviolet rays, UVA and UVC, allowing users to select the appropriate wavelength of ultraviolet light according to actual conditions. Simultaneously, by selecting a specific wavelength of ultraviolet light, especially ultraviolet light around 185 nanometers, the oxygen in the disinfection chamber 1801 can be converted into ozone for disinfection. Infrared disinfection lamps can also be used for disinfection, but compared to ultraviolet disinfection lamps, infrared disinfection lamps rely solely on heating for disinfection, typically requiring higher temperatures and longer times, which has significant disadvantages compared to the ultraviolet lamp 1102.

[0040] The chopstick tip 120 includes an installation part 1201 and a usage part 1202. The installation part 1201 can be inserted into the sterilization chamber 1801, and the usage part 1202 is fixed to the end face of the installation part 1201 away from the main chopstick body 110. A limiting ring 1203 is fixed to the middle of the outer wall of the installation part 1201. When the sterilized chopsticks are in use, the installation part 1201 is inserted into the sterilization chamber 1801 of the main chopstick body 110, and the upper end face of the limiting ring 1203 abuts against the lower end face of the main chopstick body 110. When the sterilized chopsticks are sterilized, the usage part 1202 extends into the sterilization chamber 1801, and the lower end face of the limiting ring 1203 abuts against the lower end face of the main chopstick body 110. The usage part 1202 is a platform, and the area of ​​the end face of the usage part 1202 near the installation part 1201 is larger than the area of ​​the end face of the usage part 1202 away from the installation part 1201. The inner wall of the sterilization chamber 1801 is mirror-finished. Both the cavity and the mounting part 1201 have rectangular cross-sections. The sidewalls of the cavity have rounded corners at their edges, and the corresponding sidewalls of the mounting part 1201 also have rounded corners. The main chopstick body can be made of opaque materials such as stainless steel to prevent ultraviolet rays from diffusing outwards during the sterilization process.

[0041] The inside of the electric appliance installation cavity 1802 is provided with an indicating lamp 130 for indicating the sterilization condition inside the main chopstick body 110, and a transparent window 1301 is arranged on the sidewall of the main chopstick body 110 and matched with the indicating lamp 130. A voice module such as a buzzer or a loudspeaker can be added to the main chopstick body 110 to further convey the information of the sterilization condition inside the main chopstick body 110 to the user.

[0042] The control system comprises a control switch 1401 arranged on the end face of the distal installation part 1201 of the electric appliance installation cavity 1802. The control system further comprises an infrared ray emitting end and an infrared ray receiving end arranged on the inner wall of the cavity, and the infrared ray receiving end can receive the infrared signal sent by the infrared ray emitting end. When the lower end face of the limiting ring 1203 abuts against the lower end face of the main chopstick body 110, the use part 1202 extends into the space between the infrared ray emitting end and the infrared ray receiving end. A charging port 1501 is arranged in the cavity, and a through hole 1502 for inserting a charging wire is arranged on the sidewall of the main chopstick body 110, and a waterproof silica gel plug 1503 is arranged at the through hole 1502.

[0043] The use principle and process of the sterilization chopsticks in the embodiment are as follows: in the normal state, the installation part 1201 is inserted into the sterilization cavity 1801, and when sterilization is needed, the use part 1202 is inserted into the sterilization cavity 1801, and the use part 1202 is irradiated by the ultraviolet lamp 1102, so that the use part 1202 is sterilized.

[0044] A main control unit MCU is arranged in the main chopstick body 110 for controlling the operation of the ultraviolet lamp 1102 and the indicating device, and a power supply 170 supplies power to the main control unit MCU. The indicating device used in the embodiment is an indicating lamp 130, and a buzzer alarm lamp mode can also be used.

[0045] An RTC external clock is added to the main chopstick body 110 for precise timing. The external clock circuit where the RTC is arranged can record the sterilization time and feed back to the main control unit MCU, and then the I / O interface of the main control unit MCU outputs PWM pulse waves of different frequencies to control the operation of the RGB indicating lamp 130 and the buzzer. The reset circuit and the clock circuit of the main control unit are used to control the effective operation between the programs of various circuits of the single-chip microcomputer, and if a fault occurs, the reset circuit will initialize the single-chip microcomputer.

[0046] In the embodiment, there are only two switch opening modes of the ultraviolet lamp 1102, and the sterilization can be performed only when the two switches meet the requirements. One is to open the control switch 1401, and the other is to use the infrared emitting device and the infrared receiving device to form an infrared sensing device. When the use part 1202 is inserted between the two devices and the control switch 1401 is started, the ultraviolet lamp 1102 is opened. The two switch arrangement modes use an AND gate circuit. Such arrangement mode prevents the ultraviolet rays from diffusing to the outside world and causing harm to the user after the user mistakenly touches the switch.

[0047] The charging mode of the sterilized chopsticks of the embodiment has two kinds, one is charging through the charging port 1501, and the other is using the wireless charging coil 160 to perform electromagnetic induction charging. The above charging modes can all achieve the purpose of the power supply 170. In order to enable people to know the charging condition of the sterilized chopsticks in time, an ADC detection circuit and a charging indication circuit can be arranged on the main chopstick body 110, and a power light display circuit is additionally arranged to alarm low power and serve as the charging indicator lamp 130. The above circuits are all directly connected with the power supply 170.

[0048] In summary, the above is only a preferred embodiment of the embodiment, and any changes and modifications made according to the patent application scope of the embodiment shall belong to the coverage scope of the patent of the embodiment.
