Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and more complete, the following technical solutions of the present invention will be described in detail, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the specific embodiments of the present invention belong to the protection scope of the present invention.

The use of the word "comprising" or "comprises" and the like in this disclosure means that the elements listed before the word encompass the elements listed after the word and do not exclude the possibility that other elements may also be encompassed. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be intervening devices between the specific device and the first device or the second device. When a particular device is described as being coupled to other devices, that particular device may be directly coupled to the other devices without intervening devices or may be directly coupled to the other devices with intervening devices.

All terms (including technical or scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs unless specifically defined otherwise. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

As shown in fig. 1 to 5, the noise reduction ultrasonic cleaning machine (hereinafter referred to as a cleaning machine) includes a base 1, a lid body 2, a cleaning tank 3, and an ultrasonic oscillator 4. Be provided with on the base 1 and hold chamber 10, lid 2 detachably sets up on base 1, and lid 2 is used for hiding and holds chamber 10. The wash bowl 3 is used to contain a washing liquid and an article to be washed, and the wash bowl 3 is disposed in the containing chamber 10. The ultrasonic oscillator 4 is used for generating high-frequency (about 40 KHZ) oscillation, and the high-frequency oscillation drives the cleaning liquid in the cleaning tank 3 to oscillate at high frequency to generate a cavitation effect, so that stains on glasses, cups and the like are oscillated to clean. The ultrasonic oscillator 4 is also disposed in the accommodation chamber 10, and the ultrasonic oscillator 4 is located below the cleaning tank 3. The cover body 2 and the base 1 jointly form a shell of the cleaning machine, and because the ultrasonic oscillator 4 is arranged in the shell, the noise generated when the ultrasonic oscillator 4 works needs to pass through the shell to be transmitted to the outside, so the noise of the shell can be reduced to a certain degree.

The inner wall of the accommodating cavity 10 is also provided with dense bulges 5, the bulges 5 are in a quadrangular pyramid shape, and sound is reflected for multiple times in the accommodating cavity 10 through the dense bulges 5, so that the sound is counteracted and attenuated, and the noise of the cleaning machine during working is greatly reduced. The dense protrusions 5 are preferably designed into a pyramid shape with different heights, and the dense irregular protrusions 5 are configured to make sound generate multiple disorderly reflections inside the accommodating cavity 10, so that the sound is further counteracted and attenuated.

The shape of the projection 5 may be a triangular pyramid shape, a hemispherical shape, or the like, in addition to the quadrangular pyramid shape shown in fig. 2. The dense protrusions 5 in the receiving cavity 10 may all be of the same shape; or the dense protrusions 5 of the side walls of the receiving chamber 10 are designed in one shape and the dense protrusions 5 of the bottom of the receiving chamber 10 are designed in another shape.

In order to further reduce noise, it is preferable to provide a sound-absorbing material, such as sound-absorbing wool 6, between the outer wall of the washing tub 3 and the inner wall of the receiving chamber 10, so that sound is attenuated during transmission, thereby further reducing noise.

Since the cleaning machine body has the mounting through holes 7 (such as power adapter insertion holes) and these mounting through holes 7 communicate with the accommodation chamber 10, if not closed, the noise generated by the ultrasonic oscillator 4 is directly transmitted through the mounting through holes 7, which is also a cause of making the user feel loud. In order to further reduce noise, it is preferable that a sealing ring 8 (such as a rubber ring) is provided in the mounting through hole 7, and when a power adapter plug 8 and the like are mounted in the mounting through hole 7, a gap between the mounting through hole 7 and the power adapter plug 8 can be blocked by the sealing ring 8, so that sound does not directly come out from a hole, but sound comes out only after passing through the rubber ring, so that the sealing ring 8 plays a role of sound insulation, and noise leakage is greatly reduced. In addition, the rubber ring can also play a dustproof role.

Finally, it should be noted that: the above embodiments and examples are only used to illustrate the technical solution of the present invention, but not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments and examples, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments or examples may still be modified, or some of the technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments or examples of the present invention.
