Detailed Implementation

[0026] This utility model provides a split-type ultrasonic cleaner. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0028] Please refer to Figures 1 to 6. This utility model provides a split-type ultrasonic cleaner, which can be used to clean dentures, braces, jewelry and other items. It includes a base 1, a cleaning tank 2 detachably mounted on the base 1, a cover 3 rotatably connected to the base 1, a contact-type power-conducting structure 4, and a main control circuit board 5 located inside the base 1. The cleaning tank 2 includes a housing 21, a stainless steel groove 22 located inside the housing 21, and a vibrating plate 23 located at the bottom of the stainless steel groove 22. The contact-type power-conducting structure 4 includes a female connector 41 mounted on the base 1 and a male connector 42 located at the bottom of the housing 21 and corresponding to the position of the female connector 41. The female connector 41 and the male connector 42 are plugged in to achieve power supply. The male connector 42 is electrically connected to the vibrating plate 23, and the female connector 41 is electrically connected to the main control circuit board 5. The cover 3 is used to seal the cleaning tank 2, and the cover 3 is provided with several ultraviolet germicidal lamps 6.

[0029] Since the cleaning tank 2 is detachably connected to the base 1, during use, the cleaning tank 2 is removed from the base 1, cleaning fluid and cleaning parts are poured in, and then the cleaning tank 2 is installed back onto the base 1, with the male connector 42 and female connector 41 connected. Finally, the cover 3 is closed to seal the cleaning tank 2. When the main control circuit board 5 is powered on, current flows through the male connector 42 and female connector 41, energizing the vibrating plate 23. This causes the cleaning fluid in the stainless steel tank 22 to vibrate, achieving the purpose of purifying the cleaning parts. Additionally, multiple ultraviolet germicidal lamps 6 are powered on and emit ultraviolet light towards the stainless steel tank 22, achieving a sterilization effect. After use, the cleaning parts are removed, and the cleaning tank 2 is removed from the base 1. After pouring out the cleaning fluid, the cleaning tank 2 can be directly rinsed, facilitating internal cleaning of the stainless steel tank 22. By removing the cleaning tank 2 separately for operation, there is no need to pick up and put down the entire machine, improving the convenience of equipment use.

[0030] The cleaning solution mentioned above is water, a liquid mixed with a cleaning agent, etc. The specific type of cleaning solution can be determined according to actual usage requirements and is not limited here.

[0031] In the above, by installing the female connector 41 on the base 1, the female connector 41 can be embedded inside the base 1, making it difficult for a person's hand to touch the female connector 41. This avoids the possibility of electric shock due to accidental contact with the contact-type energized structure 4 when the power is on, thus playing a role in preventing electric shock and improving the safety of equipment use.

[0032] In addition, the main control circuit board 5 is equipped with an alarm module, and the base 1 is equipped with a digital screen 9, which is electrically connected to the main control circuit board 5. The main control circuit board 5 can detect whether the male connector 42 and the female connector 41 are in the plugged-in state, that is, whether the cleaning tank 2 is correctly placed on the base 1. When the male connector 42 and the female connector 41 are not in the plugged-in state, the split-type ultrasonic cleaner is started, the main control circuit board 5 controls the power off of the female connector 41 to prevent electric shock, and sends a command to the alarm module. After receiving the command, the alarm module displays a fault code on the digital screen 9 to serve as a warning, reminding the user that the cleaning tank 2 should be correctly placed on the base 1.

[0033] In a preferred embodiment, referring to Figures 3, 5, and 6, the base 1 includes an upper shell 11 and a lower shell 12 that are interlocked. After assembly, the upper shell 11 and lower shell 12 form a closed area for mounting a female connector 41, a main control circuit board 5, and external power cords. The upper shell 11 has a first through hole 13, and the lower shell 12 has a mounting base 14 located below the first through hole 13. The female connector 41 is mounted on the mounting base 14. A sealing gasket 15 for sealing the first through hole 13 is provided between the upper shell 11 and the mounting base 14. The sealing gasket 15 has several circumferentially arranged through grooves 151, the end of which is located on the axis of the first through hole 13, as shown in Figure 6. There are three through grooves 151. The groove 151 allows the sealing gasket 15 to form three deformable portions 152. The deformable portions 152 have the characteristic of recovering deformation. When the male head 42 is not inserted into the first through hole 13, the sealing gasket 15 seals the first through hole 13 to prevent water from splashing into the machine base 1 from the first through hole 13 and causing a short circuit, thereby playing a waterproof role. When the male head 42 is inserted into the first through hole 13 and connected to the female head 41, the three deformable portions 152 deform so that the male head 42 can be inserted into the first through hole 13.

[0034] Specifically, the sealing gasket 15 is provided with a protrusion 153 extending into the through hole, and multiple through grooves 151 are located on the protrusion 153. The top surface of the protrusion 153 is flush with the top of the upper shell 11, which improves the aesthetics of the base 1 on the one hand, and avoids water accumulation on the surface of the first through hole 13 on the other hand.

[0035] Further, referring to Figures 3 and 6, the female connector 41 includes two female connector contact terminals. Correspondingly, there are two first through holes 13, with one female connector contact terminal corresponding to one first through hole 13. The sealing gasket 15 has two protrusions 153, each protrusion 153 corresponding to one first through hole 13. Each female connector contact terminal has two spring pieces 411, each spring piece 411 having a bent portion 412 protruding towards the other spring piece 411. The male connector 42 includes two male end posts, each male end post being inserted into one female connector contact terminal. After the male end post is inserted into the female connector contact terminal, the two spring pieces 411 undergo elastic deformation, causing the two bent portions 412 to engage and tightly grip the male end post, thereby ensuring the stability of the contact between the male connector 42 and the female connector 41.

[0036] Furthermore, referring to Figure 3, the bottom of the housing 21 has a recess 24 facing inward, the male head 42 is located on the recess 24, and the upper shell 11 has a protrusion 16 that mates with the recess 24, with a first through hole 13 located on the protrusion 16. The recess 24 and the protrusion 16 mate to provide positioning, facilitating the assembly of the cleaning tank 2 and the base 1. In addition, one end of the male connector is installed inside the housing 21, and the other end extends to the outside of the housing 21 and can be plugged into the female connector contact terminal. By providing a recess 24, the other end of the male connector extends into the recess 24. When the cleaning tank 2 is placed flat on the table, the bottom of the male connector is higher than the bottom of the housing 21, thus ensuring that the cleaning tank 2 is placed stably. Furthermore, the bottom of the male connector is a certain distance from the table, so that when there is water on the table, the male connector will not be immersed in the water, thus avoiding water adhering to the male connector and preventing water from being brought into the machine base 1 when the male connector is plugged into the female connector contact terminal, which could cause a short circuit.

[0037] In a preferred embodiment, referring to Figures 3 and 4, the bottom of the cover 3 has several second through holes 31, the number of which is the same as the number of ultraviolet germicidal lamps 6. A glass cover 32 is provided on each of the second through holes 31. A germicidal lamp circuit board 33 is provided inside the cover 3, and the circuit board 33 is electrically connected to the main control circuit board 5. In this embodiment, five ultraviolet germicidal lamps 6 are soldered onto the circuit board 33, and the positions of the ultraviolet germicidal lamps 6 and the glass cover 32 correspond. A sponge block 34 is provided between the circuit board 33 and the glass cover 32, and the ultraviolet germicidal lamps 6 are located inside the sponge block 34. The glass cover 32 is installed on the second through holes 31 by adhesive. During the cleaning process, the cleaning fluid in the stainless steel tank 22 will splash onto the cover 3 due to vibration. By setting the glass cover 32, the ultraviolet germicidal lamps 6 are waterproofed, and the ultraviolet rays emitted by the ultraviolet germicidal lamps 6 can pass through the glass cover 32 and dissipate into the stainless steel tank 22. In addition, a sponge block 34 is provided, which is located above the gap between the glass cover 32 and the second through hole 31. The sponge block 34 can absorb the cleaning liquid that seeps in from the gap, thereby improving the waterproof effect of the ultraviolet germicidal lamp 6.

[0038] Furthermore, the lower end of the second through hole 31 is provided with a chamfer 311, and the bottom of the cover 3 is provided with an annular groove 35, with the second through hole 31 located within the area enclosed by the annular groove 35. During the cleaning process, the cleaning fluid splashes onto the cover 3 due to vibration and flows upward along the surface of the cover 3. By providing the annular groove 35, most of the cleaning fluid is prevented from flowing into the second through hole 31. In addition, by providing the chamfer 311, the upward flow of the cleaning fluid is made more difficult, effectively reducing the amount of cleaning fluid entering the second through hole 31.

[0039] In the above embodiment, referring to Figure 5, the base 1 is provided with two symmetrically arranged fixed shafts 17. Each fixed shaft 17 has a wire hole 171. The fixed shafts 17 are rotatably connected to the cover 3, and the ends of the fixed shafts 17 extend into the interior of the cover 3. Through this arrangement, the base 1 and the cover 3 are rotatably connected. After opening the cover 3, the cleaning tank 2 can be removed from the base 1 simply by lifting it upwards. After the cleaning tank 2 is installed on the base 1 and the cover 3 is closed, the cover 3 and the base 1 cooperate to limit the position of the cleaning tank 2, preventing the cleaning tank 2 from detaching from the base 1 due to vibration.

[0040] Specifically, the main control circuit board 5 is vertically arranged inside the base 1 and close to the cleaning tank 2, so that the main control circuit board 5 is close to the fixed shaft 17. The wires used to connect the main control circuit board 5 and the germicidal lamp circuit board 33 are routed through the wire hole 171, which can avoid the wires being exposed, thereby improving the safety of the equipment. Furthermore, the wires are routed through the wire hole 171, which can prevent the wires from being broken due to repeated opening and closing of the cover 3.

[0041] In a preferred embodiment, referring to Figures 3 and 5, the top of the housing 21 is provided with a first inclined surface 211 that slopes towards the stainless steel tank 22. Cleaning fluid splashed onto the top of the housing 21 gradually gathers into large droplets, which, due to their own weight, can slide down the first inclined surface 211 into the stainless steel tank 22. Preferably, the bottom of the cover 3 is provided with a second inclined surface 36, which matches the first inclined surface 211, allowing the lower part of the cover 3 to extend into the cleaning tank 2, thus limiting the position of the cleaning tank 2 and preventing it from shifting due to vibration, thereby ensuring the stability of the cleaning tank 2 during installation.

[0042] In a preferred embodiment, referring to FIG2, the two corresponding side walls of the housing 21 are provided with anti-slip parts 7 to facilitate the user to pick up the cleaning tank 2. Specifically, the anti-slip parts 7 are recessed inward on the side walls of the housing 21, and the anti-slip parts 7 are provided with a plurality of raised anti-slip points 71, thereby improving the stability of the user holding the cleaning tank 2.

[0043] In a preferred embodiment, referring to Figure 2, the system further includes a cleaning basket 8 that can be placed inside a stainless steel tank 22. The cleaning basket 8 is used to hold the items to be cleaned, so that the cleaned items can be easily retrieved without contaminating them with human fingers. In this embodiment, the bottom of the cleaning basket 8 is provided with four support legs 81, so that the bottom of the cleaning basket 8 is a certain distance from the bottom of the stainless steel tank 22, so that the detached dirt can be deposited in the stainless steel tank 22 and will not move back into the items to be cleaned. The wall of the cleaning basket 8 is provided with a handle 82, specifically, the handle 82 has a 7-shaped structure, which makes it easier for the user to take out the cleaning basket 8.

[0044] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
