Description

Technical Field

[0001] This utility model relates to cleaning devices, and more particularly to an ultrasonic cleaner with a control box provided on the top of the cleaning tank. Background Technology

[0002] Ultrasonic cleaners are widely used in various fields such as industry, medical, electronics, and laboratories due to their high cleaning efficiency and wide range of applications. Traditional ultrasonic cleaners typically place the control panel at the front or side of the device. While this design meets basic operational needs to some extent, it still has many problems and shortcomings in practical use. Problems with existing designs:

[0003] 1. Inconvenience of Operation: Traditional ultrasonic cleaners (such as the CD-2800 model) place the control panel at the front of the device, a design that is extremely inconvenient in actual operation. Users need to frequently bend over or squat to operate the machine, which can easily lead to fatigue, especially during prolonged use. Furthermore, the front control panel design also poses a safety hazard; users may accidentally push the machine during operation, causing it to tip over and potentially resulting in equipment damage or a safety accident.

[0004] 2. Insufficient Waterproofing: Waterproofing is another significant drawback of traditional ultrasonic cleaners. For example, while the CD-2800 model is easy to operate, its control panel is located on the cover, and the wiring connects the control panel to the main control board at the bottom via the rotating shaft cavity. Because the rotating shaft cavity and the bottom are connected, waterproofing is difficult to guarantee. In actual use, especially when the operator's hands are wet, spills or other accidents could allow water to flow into the equipment along the rotating shaft, causing short circuits or damage. This design not only increases the equipment's failure rate but also poses potential safety hazards, as has already occurred in many cases.

[0005] 3. Circuit Failure Risk: Another problem with the CD-2800 model is circuit failure. Because the wiring is connected via a hinge, frequent opening and closing of the cover causes repeated friction between the wires and the hinge, potentially leading to wire breakage. This design not only reduces the equipment's lifespan but also increases maintenance costs and complexity.

[0006] 4. Limitations in Structural Design: Existing ultrasonic cleaners often struggle to simultaneously meet the requirements of ease of operation and waterproofing. For example, while the CD-2800 model solves the waterproofing issue, it is inconvenient to operate; conversely, while the CD-2800 model is easy to operate, its waterproofing is insufficient and it carries a high risk of circuit failure. This dilemma restricts the promotion and use of ultrasonic cleaners in practical applications. Summary of the Invention

[0007] To address the above deficiencies, the present invention aims to provide an ultrasonic cleaning machine with a control box at the top of the cleaning tank.

[0008] The technical solution of the present invention is as follows: An ultrasonic cleaner with a control box at the top of a steel cylinder, characterized in that it includes: a steel cylinder 5, serving as a cleaning tank for accommodating items to be cleaned; a control box, disposed on one side of the top of a pressure ring 3, with the opening facing upwards, the control box including a transparent top cover 2, a control PCB board 11, a button lens 10, and a faceplate 9, the transparent top cover 2 being made of AS material, the button lens 10 being fixed on the control box, and the faceplate 9 cooperating with the button lens 10 to achieve a seal inside the control box; a sealing structure, the sealing structure including a sealing ring 14 and a pressure ring 3, the sealing ring 14 being sleeved on the edge of the steel cylinder 5, and the pressure ring 3 cooperating with the sealing ring 14 to seal the steel cylinder 5 to the inner cylinder 6, while simultaneously achieving a waterproof seal for the control box; and a wiring structure, the wiring structure including a wiring channel from the inside of the steel cylinder 5 to the control box, the wiring channel being connected to the main PCB board 7 through a wiring hole B at the bottom of the control box.

[0011] The ultrasonic cleaning machine is characterized in that the sealing ring 14 is made of silicone rubber, and the bottom of the pressure ring 3 is provided with a protrusion that matches the sealing ring 14, so that a strong waterproof seal is achieved by locking the pressure ring 3 with the inner cylinder 6.

[0012] The ultrasonic cleaning machine is characterized in that the control box further includes a light guide column (13), which cooperates with the control PCB board (11). The control PCB board (11) is provided with a surface-mount light-emitting diode. The light of the light-emitting diode is introduced into the steel cylinder (5) through the light guide column (13). The light guide column is a nail-shaped column with a corresponding socket and nail groove at the bottom of the control box. During installation, a ring of silicone is applied in the groove, and then the light guide column is installed in it, with its surface flush with the bottom of the control box.

[0013] The ultrasonic cleaner is characterized in that a decorative position is provided on the side of the bottom shell 15, and a transparent decorative piece 8 is attached to the position. The foot piece 16 is made of silicone rubber to improve the stability of the ultrasonic cleaner.

[0014] The ultrasonic cleaning machine is characterized in that the control PCB board 11 is horizontally arranged, and the operation buttons are located on the button lens 10, so that the equipment will not move when the user operates it.

[0015] The beneficial effects of this utility model are as follows: By optimizing the structural design of the ultrasonic cleaner, the waterproof performance, ease of operation, and service life of the equipment are significantly improved. Firstly, the control box is located at the top of the steel cylinder, eliminating the need for users to bend over or squat, making operation more convenient and safer.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Figure 1 This is a schematic diagram of the ultrasonic cleaning equipment. Figure 2 This is an exploded view of an ultrasonic cleaning device; Figure 3 This is a cross-sectional view of an ultrasonic cleaning device; Figure 4This is an enlarged cross-sectional view of part A of an ultrasonic cleaning device. An ultrasonic cleaning machine with a control box at the top of the cleaning tank includes the following components: a decorative piece 1, a transparent top cover 2, a pressure ring 3, an inner basket 4, a steel cylinder 5, an inner cylinder 6, a main PCB board 7, a transparent decorative piece 8, a faceplate 9, a button lens 10, a control PCB board 11, pins 12, a light guide column 13, a sealing ring 14, a bottom shell 15, feet 16, and a power supply cover 17.

[0022] The bottom shell 15 constitutes the main structure of the entire ultrasonic cleaner. The main PCB board 7 is located at the bottom inside the bottom shell 15. There are more than three support columns at the bottom of the inner cylinder, and there are multiple matching through holes on the main PCB board 7. The support columns of the inner cylinder pass through the through holes and are fixed to the bottom shell. A decorative position can be provided on the side of the bottom shell 15, and a transparent decorative piece 8 is attached to this position. The edge of the steel cylinder 5 is fitted with a sealing ring 14 and then pressed onto the inner cylinder. The sealing ring 14 has two vertical concave rings. Along the inner diameter of the sealing ring, there is a first concave ring that matches the edge of the steel cylinder 5 in the horizontal direction, so that the sealing ring is fitted onto the steel cylinder 5. The upper surface of the sealing ring has a second concave ring along the circumference of the sealing ring. The bottom of the pressure ring 3 has a protrusion that matches the second concave ring. The protrusion of the pressure ring 3 is pressed into the second concave ring, and then the pressure ring 3 and the inner cylinder are locked together with fastening screws to achieve a strong waterproof seal. A control box is added to one side of the pressure ring 3. The control box opens upwards and has a control PCB board mounting post inside to mount the control PCB board. The control PCB board has display LEDs and a light sensor switch. The control box has a button lens and a button lens fixing post inside. The control box also includes a light guide post 13, which cooperates with the control PCB board 11. The control PCB board 11 has surface-mount LEDs. The light guide post 13 guides the light from the LEDs into the steel cylinder 5. The light guide post is a nail-shaped column with a corresponding socket and nail groove at the bottom of the control box. During installation, a ring of silicone is applied to the groove before the light guide post is installed, with its surface flush with the bottom of the control box. The bottom of the control box also has a control board wiring hole B that communicates with the bottom shell 15 for connecting the control PCB board 11 and the main PCB board 7. The button lens 10 also has an integrated surface mount. The inner ring of the pressure ring achieves a waterproof seal between the steel cylinder and the inner cylinder after being fitted with a sealing ring. The outer ring of the pressure ring has an inner groove along its periphery that matches the upper edge of the bottom shell. The upper edge of the bottom shell is completely embedded in the inner groove of the outer ring of the pressure ring, achieving an integrated seal. Since the opening is also vertical, it forms a waterproof isolation between the bottom shell and the inner cylinder and the upper part. As long as the top of the actual control box achieves good sealing and waterproofing, its interior can achieve the same high waterproof performance as the interior of the bottom shell. The control PCB board is horizontally set, and the operation buttons are also horizontally set, so when the user applies downward force, it will not cause the equipment to move. Since the control box and the transparent top cover are set separately, opening and closing the transparent top cover will not affect the control board. To further improve the waterproof performance, the height of the control box can be set to be slightly higher than the main body of the cleaning machine.

[0023] The control box is structurally designed and positioned on the top side of the pressure ring 3, with its opening facing upwards for easy user operation. The control box includes a transparent top cover 2, a control PCB board 11, a button lens 10, and a faceplate 9. The transparent top cover 2 is made of AS material, offering good transparency and waterproof performance, allowing users to observe the cleaning process inside the steel cylinder 5. The button lens 10 is fixed to the control box, and its surface features operation buttons, allowing users to operate the cleaning machine by touch. The faceplate 9 works in conjunction with the button lens 10 to seal the control PCB board 11 and the light guide column 13 within the control box, further enhancing waterproof performance. The control PCB board 11 is horizontally positioned, and the operation buttons are located on the button lens 10. When the user applies downward force, the equipment will not move, ensuring operational stability.

[0024] The sealing structure is one of the key technologies of this utility model, which includes a sealing ring 14 and a pressure ring 3. The sealing ring 14 is fitted onto the edge of the steel cylinder 5, and the pressure ring 3, by cooperating with the sealing ring 14, seals the steel cylinder 5 to the inner cylinder 6, thereby achieving a waterproof seal for the control box. The sealing ring 14 is made of silicone rubber, which has good elasticity and durability. The bottom of the pressure ring 3 has a protrusion that matches the sealing ring 14, and a strong waterproof seal is achieved by locking the pressure ring 3 to the inner cylinder 6. In addition, the outer ring of the pressure ring 3 has an inner groove that matches the upper edge of the bottom shell 15. The upper edge of the bottom shell 15 is completely embedded in the inner groove of the outer ring of the pressure ring 3, achieving an overall seal between the control box and the bottom shell 15, further improving the waterproof performance of the equipment.

[0025] The wiring structure includes a wiring channel from the inside of the steel cylinder 5 to the control box. The wiring channel connects to the main PCB board 7 via a through-hole B at the bottom of the control box. The wiring channel is designed to avoid the rotating shaft, preventing wire wear caused by shaft movement. Simultaneously, the wiring channel is sealed with a sealing ring 14 to prevent moisture from entering the control box, effectively solving the problems of wiring faults and insufficient waterproofing in existing technologies. This design not only improves the reliability of the equipment but also extends its service life.

[0026] The steel cylinder 5 serves as a cleaning tank to hold the items to be cleaned. A sealing connection is achieved between the steel cylinder 5 and the inner cylinder 6 via a sealing ring 14 and a pressure ring 3. The bottom of the inner cylinder 6 has three or more support columns, corresponding to multiple matching through holes on the main PCB board 7. The support columns of the inner cylinder 6 pass through these through holes and are fixed to the bottom shell 15, ensuring the stability of the inner cylinder 6. Both the steel cylinder 5 and the inner cylinder 6 are made of ABS, which has good corrosion resistance and mechanical strength, meeting the strength requirements of the equipment during the cleaning process.

[0027] The bottom shell 15 forms the main structure of the entire ultrasonic cleaner, with the main PCB board 7 located at the bottom inside the bottom shell 15. Decorative sections are provided on the sides of the bottom shell 15, where transparent decorative pieces 8 are attached to enhance the aesthetic appearance of the equipment. Foot tabs 16, made of silicone rubber, are installed at the bottom of the bottom shell 15 to improve the stability of the ultrasonic cleaner and prevent slippage or shaking during operation. The power cover 17 is located at the bottom of the bottom shell 15 to protect the power interface and prevent liquid and dust from entering.

[0028] To further enhance waterproofing, the control box is slightly taller than the main body of the steel cylinder 5. This design not only prevents liquid from flowing in from the top of the control box but also, to some extent, prevents liquid from flowing into the interior from the sides. Simultaneously, the height of the control box is designed for user convenience, ensuring that users do not need to frequently bend over or squat during operation, thus improving the user experience.

[0029] The above-disclosed embodiments are merely one example of the present utility model and should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the processes of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
