Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning, specifically an ultrasonic cleaning cup. Background Technology

[0002] Currently, there are ultrasonic cleaners available on the market for cleaning eyeglasses. These ultrasonic cleaners use mechanical vibrations generated by transducers to propagate in the cleaning fluid. When the ultrasonic waves propagate in the liquid, they create alternating compression and stretching phases. During the stretching phase, the pressure in the liquid decreases. When the pressure drops to a certain level, the tiny bubble nuclei in the liquid rapidly expand to form microbubbles. In the subsequent compression phase, the pressure rises sharply. These microbubbles quickly close and rupture under high pressure to form microjet streams. These microjet streams exert a strong impact on dirt, grease, dust, and other impurities on the surface of the eyeglasses, peeling these impurities off the surface and crevices of the eyeglasses and dispersing them in the cleaning fluid.

[0003] However, traditional ultrasonic cleaners can only place eyeglasses flat, causing the lenses to come into large contact with the bottom of the tank. The mechanical vibrations generated during machine operation can easily scratch the downward-facing lenses. Furthermore, the micro-jet streams generated during operation are significantly attenuated by the downward-facing side of the eyeglasses, resulting in insufficient cleaning power on the upward-facing side and failing to achieve a thorough cleaning effect. Therefore, it is necessary to develop an ultrasonic cleaning cup to solve the problems of scratching the lenses and uneven cleaning power caused by mechanical vibrations in existing ultrasonic cleaners. Utility Model Content

[0004] Regarding the aforementioned problems with existing ultrasonic cleaners that easily scratch the lens surface and cause uneven cleaning force when glasses are placed flat during mechanical vibration, the technical solution adopted by this utility model to solve these problems is as follows:

[0005] An ultrasonic cleaning cup includes a shell, a water tank located inside the shell, an ultrasonic transducer connected to the water tank, and a control board electrically connected to the ultrasonic transducer. The water tank is a cylindrical water tank that restricts the vertical placement of eyeglasses. The depth of the water tank is 100-250mm, and the width of the water tank opening is 50-100mm.

[0006] Furthermore, the water tank is made of hard metal or hard plastic.

[0007] Furthermore, the control panel is located on the lower or side side of the water tank.

[0008] Furthermore, it also includes a base detachably connected to the housing, the base having a lower coupler, the housing having an upper coupler that mates with the lower coupler, the control board being located inside the base, the control board being electrically connected to the lower coupler, and the ultrasonic transducer being electrically connected to the upper coupler.

[0009] Furthermore, the two ends of the outer shell side are concave in an arc shape towards the center.

[0010] Furthermore, the surface diameter at the upper end of the outer shell is smaller than the surface diameter at the lower end of the outer shell.

[0011] Furthermore, the water tank has a first extension portion extending outward on one side of the opening, and the outer casing has a first mounting portion that cooperates with and connects to the first extension portion, so that the water tank is connected and fixed to the outer casing.

[0012] Furthermore, it also includes a sealing ring connected to the first extension, the sealing ring wrapping around the first extension and abutting against the first mounting portion, the sealing ring being made of an elastic material.

[0013] Furthermore, a first anti-slip strip is provided on the lower side of the base, and the ultrasonic transducer is located on the side or bottom of the water tank.

[0014] Furthermore, it also includes a sealing cap connected to the upper end of the outer shell and covering the upper side of the water tank opening, the outer shell has a plurality of spiral anti-slip grooves evenly provided on its side, and the bottom of the outer shell has a second anti-slip strip.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention reduces the direct contact between the lens and the bottom of the tank by designing the water tank as a cylindrical shape to restrict the vertical placement of the glasses, thereby reducing the risk of scratching the lens. It also allows the cleaning force generated by the ultrasonic transducer to surround and act on the glasses in 360°, effectively improving the cleaning power of the ultrasonic waves on the glasses. This solves the problems of scratching the lens and uneven cleaning force that traditional ultrasonic cleaners often cause when cleaning glasses. Attached Figure Description

[0025] Please see Figures 1 to 5 An ultrasonic cleaning cup includes a shell 1, a water tank 2 located inside the shell 1, an ultrasonic transducer 3 connected to the water tank 2, and a control board 4 electrically connected to the ultrasonic transducer 3. The water tank 2 is a cylindrical water tank that restricts the vertical placement of eyeglasses. The depth of the water tank 2 is 100-250mm, and the width of the opening of the water tank 2 is 50-100mm.

[0026] In this invention, the outer shell 1 serves to protect and support the internal structure. It can be made of materials such as plastic or metal, giving it a certain strength and stability. This prevents the internal components, such as the water tank 2 and the ultrasonic transducer 3, from being impacted or damaged by external forces. It also provides insulation and waterproofing, ensuring the safe use of the ultrasonic cleaning cup. The water tank 2 is the component that holds the cleaning fluid and places the glasses. By designing the water tank 2 as a cylindrical shape that restricts the vertical placement of the glasses, direct contact between the lens and the bottom of the water tank 2 is reduced, lowering the risk of scratching the lens. It also allows the cleaning force generated by the ultrasonic transducer to surround and act on the glasses 360°, effectively improving the cleaning efficiency of the ultrasonic waves. This solves the problems of scratching the lens and uneven cleaning force that traditional ultrasonic cleaners often cause when cleaning glasses. Furthermore, the ultrasonic transducer 3 is responsible for generating ultrasonic vibrations. It is connected to the water tank 2 and transmits the ultrasonic vibrations to the cleaning fluid, forming alternating compression and stretching phases, thereby generating microjets that effectively remove dirt from the surface of the glasses.

[0027] Furthermore, by designing the depth of the water tank 2 within the range of 100-250mm, it can accommodate glasses of different sizes while ensuring sufficient space for the micro-jets generated by the ultrasonic waves to fully act on the surface of the glasses for thorough cleaning. Within this depth range, the ultrasonic waves can better interact with the cleaning fluid as they propagate, generating microbubbles of appropriate intensity and quantity, thus forming an effective micro-jets. If the water tank is too shallow, the ultrasonic waves may not be able to fully exert their effect; if the water tank is too deep, the ultrasonic energy may be excessively attenuated during propagation. Furthermore, the diameter of the water tank 2 is 50-100mm. Within this width range, it can provide a stable placement space for the glasses, making them less likely to shake or tip over during cleaning. This ensures that there is enough space for the temples of the glasses without causing instability due to an excessively large diameter, effectively improving the stability and reliability of the cleaning cup. At the same time, the appropriate diameter width can control the amount of cleaning fluid used, meeting cleaning needs while avoiding waste of cleaning fluid, effectively improving the practicality of the cleaning cup.

[0028] Furthermore, the water tank 2 is made of hard metal or hard plastic.

[0029] In this invention, the water tank 2 is made of hard metal or hard plastic. Hard metal has high strength and hardness, can withstand the vibration and impact during ultrasonic cleaning, and is not easily deformed, effectively improving the structural strength and service life of the cleaning cup. At the same time, metal materials usually have good thermal conductivity, which can make the temperature distribution of the cleaning liquid more uniform during heating or cooling, improving the cleaning effect. In addition, some metal materials also have good corrosion resistance and can adapt to different types of cleaning liquids. Hard plastic can also withstand the vibration and impact during ultrasonic cleaning to a certain extent. At the same time, it is lightweight and has a certain degree of insulation, which can reduce the risk of electric leakage during cleaning and effectively improve the safety of the cleaning cup. Specifically, hard metal can be stainless steel, aluminum alloy, and titanium alloy, but is not limited to the above materials. Hard plastic can be polypropylene, polycarbonate, and polystyrene, but is not limited to the above materials.

[0030] Furthermore, the control panel 4 is located on the lower or side side of the water tank 2.

[0031] This invention, by setting a control board 4 electrically connected to the ultrasonic transducer 3, enables precise control of the ultrasonic transducer 3. It includes a microprocessor, circuitry, and other necessary electronic components for receiving user input, processing data, and sending control signals to the ultrasonic transducer 3. For example, the control board 4 can adjust parameters such as the frequency, power, and working time of the ultrasonic waves. Users can set appropriate ultrasonic parameters according to the material and degree of dirt of the items being cleaned to achieve the best cleaning effect. Furthermore, placing the control board 4 on the lower or side of the water tank 2 fully utilizes the internal space of the cleaning cup, making the overall structure more compact and avoiding the space waste or unreasonable layout problems that might result from placing the control board 4 in other locations. This effectively improves the overall integrity and compactness of the cleaning cup.

[0032] Specifically, in this utility model, the control board 4 is equipped with a storage battery, which can provide the power required for the operation of the control board 4 and the ultrasonic transducer 3, so that the cleaning cup can be used normally without an external power source. Users can carry the cleaning cup out for use without being restricted by an external power source, which effectively improves the flexibility and practicality of the cleaning cup.

[0033] Furthermore, it also includes a base 5 detachably connected to the housing 1, the base 5 having a lower coupler 51, the housing 1 having an upper coupler 11 that is connected to the lower coupler 51, the control board 4 being located inside the base 5, the control board 4 being electrically connected to the lower coupler 51, and the ultrasonic transducer 3 being electrically connected to the upper coupler 11.

[0034] In this invention, the control board 4 is located inside the base 5, and the control board 4 and the ultrasonic transducer 3 are electrically connected to the lower coupler 51 and the upper coupler 11, respectively. Through the cooperative connection of the upper coupler 11 and the lower coupler 51, the control board 4 and the ultrasonic transducer 3 are electrically connected, while the control board 4 and the ultrasonic transducer 3 are designed as separate units. This makes the design of the cleaning cup more modular, and the separate design can effectively prevent water leakage from the water tank 2 into the outer shell 1, which would damage the control board 4 and reduce the risk of damage to the control board 4. This effectively improves the reliability and stability of the cleaning cup. The cooperative connection of the upper coupler 11 and the lower coupler 51 can further improve the electrical connection stability between the control board 4 and the ultrasonic transducer 3.

[0035] Furthermore, the two ends of the side of the outer shell 1 are concave in an arc shape towards the center.

[0036] In this invention, the two ends of the outer shell 1 are concave in an arc shape towards the center. This design conforms to ergonomics, allowing the user's fingers to rest naturally in the concave area when holding the cleaning cup, increasing the stability and comfort of the grip. This facilitates operations such as picking up, moving, adding water, and draining water, reducing the risk of the cleaning cup being dropped due to slipping. At the same time, the arc-shaped concavity can enhance the structural strength of the outer shell 1 to a certain extent, dispersing the effect of external forces on the cleaning cup. This allows the cleaning cup to better withstand and resist external impacts or pressures, reducing the possibility of breakage or damage. This effectively improves the structural strength and user experience of the cleaning cup. In addition, it also makes the cleaning cup smaller, making it easier for users to carry around.

[0037] Furthermore, the surface diameter of the upper end of the outer shell 1 is smaller than the surface diameter of the lower end of the outer shell 1.

[0038] In this invention, the surface diameter of the upper end of the outer shell 1 is smaller than the surface diameter of the lower end of the outer shell 1. This design means that the upper end of the outer shell 1 is smaller than the lower end of the outer shell 1. This design, with the upper part smaller than the lower part, makes the center of gravity of the cleaning cup lower, making it more stable when placed and less likely to tip over. Whether placed on a flat surface or during operations such as adding cleaning fluid and placing glasses to be cleaned, it can better maintain balance, reducing the risk of the cleaning cup tipping over due to accidental collisions or improper operation, reducing the possibility of cleaning fluid leakage and equipment damage, and effectively improving the stability and reliability of the cleaning cup.

[0039] Furthermore, the water tank 2 has a first extension 21 extending outward on one side of the opening, and the outer shell 1 has a first mounting part 13 that cooperates with and connects to the first extension 21, so that the water tank 2 is connected and fixed to the outer shell 1.

[0040] In this utility model, through the cooperation of the first extension 21 and the first mounting part 13, the design of the first extension 21 and the first mounting part 13 can provide accurate positioning of the water tank 2 inside the outer shell 1, ensuring that the water tank 2 is installed in the correct position, ensuring that the entire cleaning cup has a compact structure and normal function, and effectively improving the reliability of the cleaning cup. Specifically, in some embodiments, the first mounting part 13 is a groove.

[0041] Furthermore, it also includes a sealing ring 7 connected to the first extension 21, the sealing ring 7 wrapping around the first extension 21 and abutting against the first mounting portion 13, the sealing ring 7 being made of an elastic material.

[0042] This invention improves the sealing performance of the connection between the water tank 2 and the outer shell 1 by setting a sealing ring 7 between the first extension 21 of the water tank 2 and the first mounting part 13 of the outer shell 1, and by using an elastic material. This prevents the cleaning fluid from entering the interior of the outer shell 1 through the connection gap between the water tank 2 and the outer shell 1, which could damage the internal circuitry and effectively improve the structural reliability of the cleaning cup. At the same time, the elastic sealing ring 7 can act as a buffer between the water tank 2 and the outer shell 1. During the operation of the ultrasonic cleaning cup, a certain amount of vibration will be generated. The sealing ring 7 can absorb and alleviate these vibrations, reduce friction and collision between the water tank 2 and the outer shell 1, and avoid wear or loosening of components due to long-term vibration, thereby extending the service life of the cleaning cup. Specifically, the elastic material can be silicone, rubber, thermoplastic elastomer, etc.

[0043] Furthermore, the base 5 is provided with a first anti-slip strip 52 on its lower side, and the ultrasonic transducer 3 is located on the side or bottom of the water tank 2.

[0044] In this utility model, by providing a first anti-slip strip 52 on the lower side of the base 5, the friction between the base 5 and the placement surface is increased, preventing the cleaning cup from sliding or shifting due to ultrasonic vibration or external force during operation, ensuring that the cleaning cup can be placed stably on the table, reducing the risk of cleaning liquid overflow or the cleaning cup falling and being damaged due to position movement, and further buffering the mechanical vibration generated by the ultrasonic transducer 3. Specifically, the first anti-slip strip 52 is made of elastic material.

[0045] Furthermore, the ultrasonic transducer 3 is located on the side or bottom of the water tank 2. When the ultrasonic transducer 3 is connected to the bottom of the water tank 2, the micro-jet generated by the ultrasonic transducer 3 can clean both sides of the lens from bottom to top, effectively removing dirt from the lens surface. When the ultrasonic transducer 3 is connected to the side of the water tank 2, preferably multiple ultrasonic transducers 3 are provided. Multiple ultrasonic transducers 3 are evenly connected to the side of the water tank 2. By generating ultrasonic waves in 360° through multiple ultrasonic transducers 3 connected to the side of the water tank 2, the glasses placed vertically in the water tank 2 are cleaned, ensuring the cleanliness of both sides of the glasses by the ultrasonic cleaning cup and effectively improving the cleaning ability of the ultrasonic cleaning cup.

[0046] Furthermore, it also includes a sealing cap 6 connected to the upper end of the outer shell 1 and covering the upper side of the water tank 2 opening. The outer shell 1 has a plurality of spiral anti-slip grooves 12 evenly distributed on its side, and a second anti-slip strip 14 is provided at the bottom of the outer shell 1.

[0047] In this invention, the sealing cap 6 effectively prevents the cleaning fluid from splashing out due to ultrasonic vibration, maintaining the cleanliness of the surrounding environment and preventing damage or contamination to other items. It also reduces heat loss from the cleaning fluid, especially in cleaning cups with heating functions, helping to maintain the temperature of the cleaning fluid and improve cleaning effectiveness. Furthermore, it prevents dust and debris from entering the water tank 2. Moreover, by evenly distributing multiple spiral anti-slip grooves 12 on the side of the outer shell 1, it provides a more comfortable and stable grip, making it easier for users to pick up and move the cleaning cup. Especially when there is water or cleaning fluid on the surface of the cleaning cup, it effectively prevents slippage and dropping. Additionally, compared to ordinary flat surfaces or simple textures, the spiral anti-slip grooves offer superior grip. The groove 12 greatly increases the friction between the hand and the outer shell 1, allowing the user to hold the cleaning cup more firmly during operation, improving the safety and stability of operation, and reducing the risk of accidental drops. Furthermore, by setting a second anti-slip strip 14 at the bottom of the outer shell 1, the stability of the cleaning cup when placed is further improved, preventing it from sliding or shaking on the table. Especially when the cleaning cup is working, the ultrasonic vibration may cause the cleaning cup to shift to a certain extent. The second anti-slip strip 14 can effectively reduce this shift, ensuring that the cleaning cup always stays in a fixed position. At the same time, it can also play a certain buffering role, reducing friction and collision between the bottom of the outer shell and the placement surface, preventing the bottom from being worn or scratched, and extending the service life of the cleaning cup. Specifically, the second anti-slip strip 14 is made of elastic material.
