[0035] The following will be combined with Figures 1 to 6 to illustrate the embodiments of the present invention.

[0036] This embodiment relates to an ultrasonic cleaning machine, including:

[0037] Power supply component, the power supply component includes a bottom box 11, a positive power supply column 12, and a negative power supply column 13. The positive power supply column 12 and the negative power supply column 13 are both arranged on the bottom box 11, and the upper ends of the positive power supply column 12 and the negative power supply column 13 extend out of the bottom box 11;

[0038] Cleaning component, the cleaning component includes a chamber body 21, an ultrasonic power supply board 22, and an ultrasonic transducer 23. An upward-opening cleaning groove 2111 is provided on the chamber body 21. The ultrasonic transducer 23 and the ultrasonic power supply board 22 are both arranged inside the chamber body 21. The ultrasonic transducer 23 abuts against the bottom wall of the cleaning groove 2111. The ultrasonic power supply board 22 supplies power to the ultrasonic transducer 23. The ultrasonic power supply board 22 is provided with a positive contact piece 221 and a negative contact piece 222. The ultrasonic power supply board 22 abuts against the bottom wall of the chamber body 21, and the chamber body 21 is provided with avoidance through holes at the positive contact piece 221 and the negative contact piece 222. The positive power supply column 12 passes through the avoidance through hole and abuts against the positive contact piece 221, and the negative power supply column 13 passes through the avoidance through hole and abuts against the negative contact piece 222;

[0039] Connection component, the connection component includes a first magnet 31 arranged on the chamber body 21 and a second magnet 32 arranged on the bottom box 11. The first magnet 31 and the second magnet 32 are attracted to each other.

[0040] By arranging the ultrasonic oscillation component inside the chamber body 21, when the user replaces the chamber body 21, the ultrasonic oscillation component is replaced together. The user does not need to reassemble the ultrasonic oscillation component again, which well improves the poor vibration transmission caused by poor assembly after the user replaces it. In addition, the cleaning component and the power supply component are connected by the first magnet 31 and the second magnet 32 of the connection component, ensuring reliable and convenient connection between the cleaning component and the power supply component.

[0041] Further, the bottom box 11 includes an upper box cover 111 and a lower box cover 112. The upper box cover 111 and the lower box cover 112 are connected together. At least two positioning posts 1121 are provided on the lower box cover 112. The power supply assembly includes a power board 14. On the top surface of the power board 14, there are a positive elastic plunger and a negative elastic plunger that are not connected to each other. A through first column hole and a second column hole are provided on the upper box cover 111. The positive power supply column 12 and the negative power supply column 13 respectively pass through the first column hole and the second column hole and extend upward. The positive contact piece 221, the positive power supply column 12, and the positive elastic plunger are electrically connected in sequence, so that the negative contact piece 222, the negative power supply column 13, and the negative elastic plunger are electrically connected in sequence. The positive elastic plunger and the negative elastic plunger both adopt conductive materials in this embodiment. The positive elastic plunger and the negative elastic plunger of the power board 14 respectively abut against the positive power supply column 12 and the negative power supply column 13. The positive elastic plunger has elasticity. Thus, when the positive contact piece 221 and the negative contact piece 222 of the cleaning assembly contact the positive power supply column 12 and the negative power supply column 13 of the power supply assembly respectively under the action of the first magnet 31 and the second magnet 32 of the connection assembly, problems such as hard contact causing damage can be effectively improved.

[0042] In this embodiment, two positioning holes are provided on the power board 14. The two positioning holes are respectively sleeved outside the two positioning posts 1121 to position and install the power board 14 on the lower box cover 112, so as to ensure that the power board 14 can be positioned and installed on the lower box cover 112 to ensure the accurate positioning of the positive power supply column 12 and the negative power supply column 13 provided on the power board 14.

[0043] In this embodiment, there are two power supply modes. The first power supply mode is plug-in power supply. In the plug-in power supply mode, the power supply assembly further includes a power supply socket 142 and a switch button. The switch button and the power supply socket 142 are both exposed through an opening preset on the bottom box 11. The power supply socket 142 is electrically connected to both the positive power supply column 12 and the negative power supply column 13, and the switch button is connected in series between the power supply socket 142 and the positive power supply column 12 or the negative power supply column 13 to control whether to supply power. When using this ultrasonic cleaner, the power supply line is connected to the power supply insertion point to supply power to the power board 14. Then, pressing the switch button can start the ultrasonic transducer 23 to vibrate the chamber body 21, thereby starting the cleaning function.

[0044] The second mode is to supply power to the rechargeable battery 141. In the power supply mode of the rechargeable battery 141, the power supply component includes the rechargeable battery 141, the power supply socket 142, and the switch button. The rechargeable battery 141 supplies power to the positive power supply column 12 and the negative power supply column 13 through the power board 14, and then supplies power to the ultrasonic transducer 23. The switch button is also connected in series between the power supply socket 142 and the positive power supply column 12 or the negative power supply column 13 to control whether to supply power. The power supply socket 142 charges the rechargeable battery 141 when the power of the rechargeable battery 141 is low.

[0045] Further, a positioning sleeve 1111 is also provided on the lower side of the first column hole. The cross-section of the positive power supply column 12 is in a "T" shape, and the wider side of the positive power supply column 12 is restricted at the positioning sleeve 1111. The positioning sleeve 1111 is designed on the lower side of the first column hole, and the positive power supply column 12 is configured with a matching "T"-shaped cross-section, so that the positioning and connection of the positive power supply column 12 are more accurate. In addition, furthermore, in this embodiment, both the upper box cover 111 and the lower box cover 112 are plastic parts, and the upper box cover 111 and the lower box cover 112 are connected by ultrasonic waves. The wider side of the positive power supply column 12, that is, the lower side in this embodiment, is sleeved with the positioning sleeve 1111, which can increase the contact area between the positive power supply column 12 and the upper box cover 111, increase the friction force between the two, and reduce the chance of loosening due to vibration during the ultrasonic processing.

[0046] In this embodiment, the bin body 21 includes an upper bin shell 211 and a lower bin shell 212. The cleaning groove 2111 is provided on the upper bin shell 211. The upper bin shell 211 and the lower bin shell 212 are ultrasonically connected to form the bin body 21. By ultrasonically connecting the upper bin shell 211 and the lower bin shell 212 to form the bin body 21, it has the characteristic of being non-detachable after formation, which can effectively prevent users from disassembling and damaging. In addition, ultrasonic connection has the advantages of convenient connection and low cost.

[0047] Further, a magnet slot 2121 is provided on the bottom wall of the bin body 21. A number of inwardly protruding plugs 21211 are provided inside the magnet slot 2121. The first magnet 31 is inserted into the magnet slot 2121 and tightly abuts against the plugs 21211. The bottom wall of the bin body 21, in this embodiment, is the lower bin shell 212 specifically. At this time, the magnet slot 2121 is provided on the surface of the lower bin shell 212 facing the upper bin shell 211. Thus, when the first magnet 31 is assembled with the magnet slot 2121, the first magnet 31 is located inside the bin body 21, which can protect the first magnet 31. The plugs 21211 are designed inside the magnet slot. When the first magnet 31 is inserted into the magnet slot 2121, the first magnet 31 contacts the inner sides of the plugs 21211. Since the contact area between the plugs 21211 and the first magnet 31 is small, the resistance when the first magnet 31 is inserted into the magnet slot 2121 is small, and it is not easy to come out after being inserted into the magnet slot 2121.

[0048] Further, the surface of the plug 21211 adjacent to the inner side of the magnet slot 2121 is an inclined surface, and the thickness of the plug 21211 gradually increases from the open side inward. By setting the inner surface of the plug 21211 as an inclined surface, when the first magnet 31 is inserted into the plug 21211, the first magnet 31 will be more tightly fitted with the plug 21211 as it is continuously inserted into the magnet slot 2121.

[0049] Further, the number of the first magnets 31 is three. One of the first magnets 31 is arranged on the left side of the bin body 21, and the other two first magnets 31 are respectively arranged beside the positive contact piece 221 and the negative contact piece 222. Each first magnet 31 is respectively inserted into a magnet slot 2121. By configuring three first magnets 31 and arranging two of them beside the positive contact piece 221 and the negative contact piece 222, the contact reliability between the positive contact piece 221 and the negative contact piece 222 can be effectively ensured. In this embodiment, the number of the corresponding second magnets 32 is also three, and the arrangement positions of the three second magnets 32 correspond to the arrangement positions of the first magnets 31. In addition, each second magnet 32 is also correspondingly provided with a magnet slot 2121 to conveniently realize the connection between the second magnet 32 and the bottom box 11. Further, in this embodiment, the second magnets 32 are all arranged on the surface of the upper box cover 111 facing the lower box cover 112, so as to ensure that when the user disassembles the bin body 21 from the bottom box 11, the second magnets 32 are in an invisible state, which plays a role in protecting the second magnets 32. In this embodiment, the two first magnets 31 and the power supply board beside the positive contact piece 221 and the negative contact piece 222 are pressed on the bottom wall of the lower bin shell 212 by a pressing cover 311, thereby further ensuring the connection reliability between the positive contact piece 221, the negative contact piece 222 and the outside.

[0050] When a conventional ultrasonic cleaning machine is in use, the vibration generated by the ultrasonic transducer 23 can not only cause the cleaning liquid placed in the cleaning groove 2111 to vibrate to clean the objects, but also easily cause the vibration of the entire ultrasonic cleaning machine, especially for small ultrasonic cleaning machines used to clean small objects such as colored contact lenses and soft contact lenses.

[0051] In this embodiment, the connecting wall 2114 between the cleaning groove 2111 and the ultrasonic transducer is used as the oscillating wall 2113. The vertical side wall of the cleaning groove 2111 is the connecting wall 2114. The oscillating wall 2113 is used to fit with the ultrasonic transducer 23 and transmit vibration. The thickness of the oscillating wall 2113 is smaller than that of the connecting wall 2114. By designing the thickness of the oscillating wall 2113 to be smaller than that of the connecting wall 2114, on the one hand, the oscillating wall 2113 can transmit the vibration of the ultrasonic oscillator well, and on the other hand, the vibration of the ultrasonic oscillator is not easily transmitted to the connecting wall 2114 and is not easily transmitted to other positions through the connecting wall 2114 to cause the vibration of the entire ultrasonic cleaning machine.

[0052] Further, a partition wall 2115 is further provided in the cleaning groove 2111. The partition wall 2115 divides the cleaning groove 2111 into independent first sub-grooves 21111 and second sub-grooves 21112. By configuring the partition wall 2115 to divide the cleaning groove 2111 into independent first sub-grooves 21111 and second sub-grooves 21112, two objects can be cleaned simultaneously.

[0053] Further, a connecting bone 2112 extending outward is further provided on the upper part of the connecting wall 2114. The connecting bone 2112 is annular. A first limiting boss 21121 and a second limiting boss 21122 are provided on the lower side of the connecting bone 2112. By providing the connecting bone 2112 and the first limiting boss 21121 and the second limiting boss 21122 on the outer side of the connecting wall 2114, it is very convenient to be positioned and connected with the bottom box 11. When assembled with the bottom box 11, the wall surface of the bottom box 11 can be stuck between the first limiting boss 21121 and the second limiting boss 21122.

[0054] Further, the thickness of the oscillating wall 2113 is 0.6 - 1 mm. The thickness of the oscillating wall 2113 is set to 0.6 mm to 1 mm. It has a certain structural strength and can achieve a good effect of transmitting the vibration of the ultrasonic oscillator. At the same time, the ultrasonic vibration is not easily transmitted to the connecting wall 2114.

[0055] Further, the thickness of the connecting wall 2114 is 1.6 - 2.3 mm. The thickness of the connecting wall 2114 is designed to be 1.6 - 2.3 mm, which can have a high structural strength, separate the vibration of the oscillating wall 2113 well, and be integrally formed with the oscillating wall 2113 during injection molding.

[0056] Further, the ultrasonic cleaning machine further includes a top cover 51 and a cleaning sealing ring 52. The top cover 51 is rotatably connected to the bin body 21 to open or close the cleaning groove 2111. The cleaning sealing ring 52 is movably arranged between the top cover 51 and the cleaning groove 2111, and seals the gap between the top cover 51 and the top wall of the cleaning groove 2111 when the top cover 51 closes to seal the cleaning groove 2111. By configuring the top cover 51 and the cleaning sealing ring 52, the problem of liquid leakage can be better avoided during cleaning by closing the cleaning groove 2111 with the top cover 51 and the cleaning sealing ring 52. In this embodiment, when the cleaning groove 2111 is divided into a first sub-groove 21111 and a second sub-groove 21112 by the partition wall 2115, the problem of liquid cross-flow between the first sub-groove 21111 and the second sub-groove 21112 can be effectively improved.

[0057] The above has specifically described the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present invention.
