[0007] As described above, an ultrasonic cleaning machine for ozone sterilization and disinfection has an inner tank vent on its side wall and a base vent on its side wall. The ozone delivery pipe passes through the base vent and the inner tank vent in sequence and enters the inner tank. Sealing rings are provided between the base vent and the ozone delivery pipe, and between the inner tank vent and the ozone delivery pipe.

[0008] An ultrasonic cleaning machine for ozone sterilization and disinfection as described above, the base includes an upper shell, a lower shell located below the upper shell, and an end cap located above the upper shell. The upper shell has a first mounting cavity and a second mounting cavity, and a third mounting cavity is provided between the upper shell and the lower shell. The end cap has a through hole communicating with the first mounting cavity. A first waterproof structure is provided at the connection between the upper shell and the lower shell, and a second waterproof structure is provided at the connection between the upper shell and the end cap.

[0009] As described above, in an ultrasonic cleaning machine for ozone sterilization and disinfection, the first waterproof structure includes a water-blocking part disposed on the lower shell. The water-blocking part is located at the connection between the lower shell and the upper shell and extends upward. When the lower shell is connected to the upper shell, the inner sidewall of the upper shell is located outside the water-blocking part.

[0010] As described above, an ultrasonic cleaning machine for ozone sterilization and disinfection has a first connecting part connected to the ozone sterilization component and a second connecting part connected to the circuit board on the side of the upper shell facing the third mounting cavity. The distance between the bottom of the first connecting part and the bottom surface of the lower shell is greater than the height of the ozone sterilization component, and the distance between the bottom of the second connecting part and the bottom surface of the lower shell is greater than the height of the circuit board.

[0011] As described above, in an ultrasonic cleaning machine for ozone sterilization and disinfection, the second waterproof structure includes a sealing element disposed between the end cap and the upper shell, the inner cleaning tank is provided with a flange extending outward in the circumferential direction, and the sealing element is provided with a sealing groove that cooperates with the flange.

Detailed Implementation

[0028] 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 a part of the embodiments of the present utility model, and not all of them. 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.

[0029] Please see the appendix Figure 1 To be continued Figure 8 This embodiment provides an ultrasonic cleaner for ozone sterilization and disinfection, including a base 1. The base 1 has a first mounting cavity 101, a second mounting cavity 102, and a third mounting cavity 103. The second mounting cavity 102 is located on the outer periphery of the first mounting cavity 101, and the third mounting cavity 103 is located below the first mounting cavity 101 and communicates with the second mounting cavity 102. The first mounting cavity 101 has a cleaning inner tank 2 and an ultrasonic component 3 connected to the cleaning inner tank 2. The third mounting cavity 103 has an ozone sterilization component 4 and a circuit board 5 electrically connected to the ultrasonic component 3 and the ozone sterilization component 4. The ozone sterilization component 4 includes an ozone generator 41 and an ozone delivery pipe 42. One end of the ozone delivery pipe 42 is connected to the ozone generator 41, and the other end passes through the second mounting cavity 102 and through the side wall of the cleaning inner tank 2 before entering the cleaning inner tank 2.

[0030] This embodiment of an ultrasonic cleaner with ozone sterilization and disinfection features an ozone generator 41 that generates ozone, which is then delivered to the inner cleaning tank 2 via an ozone delivery pipe 42. After dissolving in water, the ozone quickly diffuses to all parts of the water, effectively sterilizing and disinfecting even areas with obstructions. Furthermore, the ozone delivery pipe 42 passes through the side wall of the inner cleaning tank 2 before entering the tank, allowing for faster and wider diffusion of ozone into the water, thus improving the overall sterilization and disinfection effect.

[0031] Specifically, the ozone sterilization component 4 in this embodiment also includes an air pump (not shown in the figure). The air pump is connected to the ozone generator 41. The air pump sends air into the ozone generator 41. The ozone generator 41 decomposes the oxygen molecules in the air into oxygen atoms. The oxygen atoms then combine with oxygen molecules to produce ozone. The ozone delivery pipe 42 delivers the generated ozone to the cleaning inner tank 2, thereby allowing the ozone to diffuse to all parts of the water body and achieve thorough ozone disinfection.

[0032] Specifically, the ultrasonic component 3 in this embodiment includes an ultrasonic transducer, which is a device capable of converting electrical energy into mechanical energy and is widely used in various fields such as industry, medicine, and testing. The cleaning inner tank 2 in this embodiment is made of steel, and the cleaning inner tank 2 and the ultrasonic component 3 can be connected by adhesive. This embodiment utilizes the high-frequency vibration and cavitation effect of ultrasound to effectively remove dirt and grease from the surface of objects, and is especially suitable for cleaning complex shapes and small crevices.

[0033] Furthermore, the ozone delivery pipe 42 enters the cleaning inner tank 2 at one end, which is inclined downward and extends towards the bottom surface of the cleaning inner tank 2. This can effectively extend the distance between the ozone and the water surface, increase the contact time between the ozone and the water, and allow the ozone to dissolve more fully in the water for sterilization and disinfection.

[0034] Furthermore, the side wall of the inner cleaning tank 2 is provided with an inner tank vent 21, and the side wall of the base 1 is provided with a base vent 104. The ozone delivery pipe 42 passes through the base vent 104 and the inner tank vent 21 in sequence before entering the inner cleaning tank 2. Sealing rings (not shown in the figure) are provided between the base vent 104 and the ozone delivery pipe 42, and between the inner tank vent 21 and the ozone delivery pipe 42. The inner tank vent 21 and the base vent 104 can define the position of the ozone delivery pipe 42. Preferably, in this embodiment, the positions of the inner tank vent 21 and the base vent 104 correspond, and the height of the inner tank vent 21 on the inner cleaning tank 2 is less than half of the overall height of the inner cleaning tank 2.

[0035] Further, the base 1 includes an upper shell 11, a lower shell 12 located below the upper shell 11, and an end cap 13 located above the upper shell 11. The upper shell 11 has a first mounting cavity 101 and a second mounting cavity 102. A third mounting cavity 103 is provided between the upper shell 11 and the lower shell 12. The end cap 13 has a through hole 131 communicating with the first mounting cavity 101. A first waterproof structure is provided at the connection between the upper shell 11 and the lower shell 12, and a second waterproof structure is provided at the connection between the upper shell 11 and the end cap 13. The first waterproof structure waterproofs the connection between the upper shell 11 and the lower shell 12, preventing external moisture from entering the second mounting cavity 102 and the third mounting cavity 103 from the connection between the upper shell 11 and the lower shell 12, thus protecting the ozone sterilization component 4 and the circuit board 5. The second waterproof structure waterproofs the connection between the upper shell 11 and the end cap 13, preventing moisture from entering the first mounting cavity 101, thus protecting the ultrasonic component 3.

[0036] Furthermore, the first waterproof structure includes a water-blocking portion 121 disposed on the lower shell 12. The water-blocking portion 121 is located at the connection between the lower shell 12 and the upper shell 11 and extends upward. When the lower shell 12 is connected to the upper shell 11, the inner sidewall of the upper shell 11 is located outside the water-blocking portion 121. When water enters the connection between the lower shell 12 and the upper shell 11, it cannot continue to enter the second mounting cavity 102 and the third mounting cavity 103 due to the water-blocking effect of the water-blocking portion 121. This effectively protects the ozone sterilization component 4 and the circuit board 5 in the third mounting cavity 103, effectively preventing the ozone sterilization component 4 and the circuit board 5 from coming into contact with water and causing short circuits or other hazards.

[0037] Furthermore, the lower shell 12 is provided with a water-blocking groove 122, which is located on the outside of the water-blocking part 121. The upper shell 11 is provided with a flange 114 that mates with the water-blocking groove 122. The mating of the water-blocking groove 122 and the flange 114 further positions and engages the lower shell 12 and the upper shell 11. When water vapor enters the connection between the lower shell 12 and the upper shell 11, it will first enter the water-blocking groove 122. The water-blocking groove 122 relatively increases the height of the water-blocking part 121, making it more difficult for water vapor to cross the water-blocking part 121 and enter the second mounting cavity 102 and the third mounting cavity 103.

[0038] Furthermore, the upper shell 11 has a first connecting part 111 connected to the ozone sterilization component 4 and a second connecting part 112 connected to the circuit board 5 on the side facing the third mounting cavity 103. The distance between the bottom of the first connecting part 111 and the bottom surface of the lower shell 12 is greater than the height of the ozone sterilization component 4, and the distance between the bottom of the second connecting part 112 and the bottom surface of the lower shell 12 is greater than the height of the circuit board 5. In this embodiment, the first connecting part 111 and the second connecting part 112 are corresponding connecting posts. The ozone sterilization component 4 is connected to the first connecting part 111 and locked with bolts, and the circuit board 5 is connected to the second connecting part 112 and locked with bolts. Thus, the bottom of the ozone sterilization component 4 is kept at a certain distance from the bottom surface of the lower shell 12, and the circuit board 5 is kept at a certain distance from the ground of the lower shell 12. This not only facilitates heat dissipation, but also makes it difficult for moisture to contact the ozone sterilization component 4 and the circuit board 5 even if it enters the third mounting cavity 103, further providing safety protection for the ozone sterilization component 4 and the circuit board 5.

[0039] Furthermore, the second waterproof structure includes a sealing element 6 disposed between the end cap 13 and the upper shell 11. The cleaning inner tank 2 is provided with a flange 22 extending outward in the circumferential direction, and the sealing element 6 is provided with a sealing groove 61 that mates with the flange 22. The sealing element 6 is located above the first mounting cavity 101 and is disposed around the edge of the first mounting cavity 101. When the end cap 13 is connected to the upper shell 11, the sealing element 6 is pressed between the end cap 13 and the upper shell 11, thereby achieving a seal between the sealing element 6 and the flange 22, between the sealing element 6 and the upper shell 11, and between the sealing element 6 and the end cap 13. This effectively prevents moisture or cleaning liquid from entering the first mounting cavity 101 through the gap between the sealing element 6 and the flange 22, or through the gap between the sealing element 6 and the upper shell 11, or through the gap between the sealing element 6 and the end cap 13. Preferably, waterproof protrusions are provided on both the side of the end cap 13 facing the seal 6 and the side of the upper shell 11 facing the seal 6, so as to more securely press the seal 6 between the end cap 13 and the upper shell 11.

[0040] Furthermore, the end cap 13 has a positioning groove 132 at the end near the first mounting cavity 101, and the sealing member 6 is positioned and installed in the positioning groove 132. The end cap 13 away from the first mounting cavity 101 has a downwardly extending abutment portion 133, and the upper shell 11 has an upwardly extending waterproof portion 113. When the upper shell 11 is connected to the end cap 13, the abutment portion 133 is located outside the waterproof portion 113. Thus, at the connection between the end cap 13 and the upper shell 11, the end near the first mounting cavity 101 is sealed and waterproofed by the sealing member 6, while the end away from the first mounting cavity 101 is waterproofed by the cooperation of the waterproof portion 113 and the abutment portion 133, resulting in a better waterproofing effect.

[0041] Furthermore, the diameter of the through hole 131 is larger than the diameter of the inner cleaning liner 2 and smaller than the diameter of the first mounting cavity 101. An arc-shaped transition section 23 is provided between the side wall of the inner cleaning liner 2 and the flange 22. Thus, water dripping from the end cap 13 can enter the inner cleaning liner 2 along the arc-shaped transition section 23, which can effectively prevent water droplets from accumulating in the flange 22 or in the seal 6.

[0042] Preferably, the base 1 is provided with anti-slip pads 106 at the bottom and a power interface 107 on the side wall of the base 1. The power interface 107 connects the circuit board 5 and an external power source to supply power to the circuit board 5. The power interface 107 is provided with a detachable waterproof plug 108.

[0043] Furthermore, the base 1 is provided with a hinged cover 7, and an ultraviolet lamp 71 is provided on the side of the cover 7 facing the inner cleaning tank 2. An observation window 72 is provided on the cover 7, located in the center of the cover 7, and several ultraviolet lamps 71 are arranged at intervals around the circumference of the observation window 72. The observation window 72 is made of a transparent material such as glass or transparent plastic to facilitate user observation of the cleaning status of items inside the inner cleaning tank 2. This embodiment of an ozone-based sterilization and disinfection ultrasonic cleaner can perform ozone sterilization and disinfection, ultraviolet lamp sterilization and disinfection, and simultaneous ozone and ultraviolet lamp sterilization and disinfection, meeting various user needs.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
