Description

Technical Field

[0001] This utility model relates to the field of ultrasonic cleaning equipment technology, and in particular to a sealing and waterproof structure for an ultrasonic cleaning machine. Background Technology

[0002] The working principle of an ultrasonic cleaner is based on the cavitation, acceleration, and direct flow effects of ultrasound in liquids. When the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagates into the cleaning solvent, the ultrasound waves radiate forward in the cleaning liquid in alternating dense and sparse phases, causing the liquid to flow and generate tiny bubbles. These bubbles vibrate, form, and grow under the action of ultrasound, and when they reach a certain sound pressure, they rapidly increase in size and suddenly close, generating shock waves that break down insoluble dirt and disperse it in the cleaning liquid, thereby achieving the purpose of cleaning.

[0003] After the operator removes the workpiece from the cleaning solution, they need to wipe it with paper or cloth, which can cause the workpiece surface to become contaminated with debris or fibers again. To address these issues, Chinese patent CN214976271U discloses an ultrasonic cleaning machine. This machine uses a hot air blower and an air outlet pipe. The air outlet pipe blows hot air to the bottom of the cleaning tank, carrying away the cleaning solution adhering to the workpiece surface with the rising hot air, thus drying the workpiece. This reduces the need for wiping the workpiece with paper or cloth, thereby lowering the risk of secondary contamination. When the rotating plate flips, the operator can easily monitor the liquid level in the cleaning tank and stop adding cleaning solution, reducing the risk of cleaning solution entering the air outlet pipe and extending the lifespan of the hot air blower.

[0004] The ultrasonic cleaner lacks a sealed waterproof structure at the connection points of components such as the air outlet duct and air filter. As a result, the cleaning fluid in the cleaning chamber can easily flow into the installation chamber and damage the hot air blower. At the same time, moisture from the outside air can also enter the installation chamber through the gaps in the outer wall of the cleaner body and damage the hot air blower, seriously affecting the service life of the ultrasonic cleaner.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

The present invention provides the following embodiments.

[0032] Reference Figure 1-5 This utility model provides an embodiment of a sealing and waterproof structure for an ultrasonic cleaner, comprising a bottom cover 1, with a vent hole and multiple screw holes at the bottom of the bottom cover 1, a groove at the top outer edge of the bottom cover 1, and multiple sets of waterproof silicone pads 2 installed at the bottom outer edge of the bottom cover 1. By setting the waterproof silicone pads 2, the screw holes of the bottom cover 1 can be plugged. A waterproof and breathable membrane 3 is also installed at the bottom of the bottom cover 1, which is installed in the vent hole at the bottom of the bottom cover 1. A waterproof DC seat 4 penetrates the inner wall of the bottom cover 1, and a main sealing ring 5 is installed at the top outer edge of the bottom cover 1, which is installed in the groove at the top outer edge of the bottom cover 1.

[0033] A main board 6 is installed in the bottom cover 1. An inner bracket 7 is installed above the main board 6. A through-hole is opened at the bottom center of the inner bracket 7, and a conductive component is installed in the hole. A steel channel component 8 is fitted into the inner wall of the inner bracket 7. The bottom surface of the steel channel component 8 is in close contact with the top surface of the conductive component. A steel channel sealing ring 9 is installed on the top of the steel channel component 8. The outer wall of the inner bracket 7 is fitted with a housing body 10. It is worth noting that the bottom end of the outer wall of the housing body 10 is vertically fitted into the groove at the top outer edge of the bottom cover 1, compressing the housing sealing ring 5. Two sets of symmetrical stop grooves are opened on the inner wall of the bottom cover 1, and waterproof silicone rings are fitted into the inner walls of the stop grooves. During the process of tightening the housing body 10 and the bottom cover 1 with screws, it can be ensured that the waterproof silicone rings are evenly and effectively compressed, thus achieving the expected waterproof effect and ensuring that the equipment can operate normally in various environments without being affected by water intrusion. A groove is opened at the top outer edge of the inner wall of the housing body 10, and a steel channel sealing ring 9 is installed in the groove.

[0034] A lower cover 11 is mounted on the top of the main body 10. A fixing film 12 is installed in the lower cover 11, and a light panel 13 is mounted on top of the fixing film 12. An upper cover 14 is mounted on the outer edge of the top of the lower cover 11. The contact surface between the lower cover 11 and the upper cover 14 is designed to be waterproof using ultrasonic welding technology. This welding method not only ensures a tight connection between the two components, but also effectively prevents water penetration by precisely controlling the energy output during the welding process, thus providing reliable protection for the internal electronic components. A waterproof O-ring 15 is fitted on the outer wall of the waterproof DC socket 4. During the assembly of the waterproof DC socket 4 and the bottom cover 1, the waterproof O-ring 15 can be effectively compressed by tightening screws to ensure a tight fit. This achieves an ideal waterproof effect, ensuring that electronic devices can work normally in various environments without being affected by water intrusion. The upper cover 14 is equipped with a first-grade waterproof UV adhesive 16, and the electrode springs in the upper cover 14 utilize the first-grade waterproof UV adhesive 16 for waterproof structure. The outer shell 10 is equipped with a second-grade waterproof UV adhesive 17. Multiple sets of through holes are opened at the top outer edge of the outer shell 10, and spring pins are installed in each hole. The contact position between the outer wall of the spring pin and the through hole utilizes the second-grade waterproof UV adhesive 17 for waterproof structure. A waterproof silicone ring 18 is installed in the steel channel sealing ring 9. By using screws to tightly fix the inner bracket 7 to the outer shell 10, the waterproof silicone ring 18 can be effectively compressed, thereby achieving the dual effects of shock absorption and waterproofing.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
