[0018] Example 1 A load-bearing ultrasonic cleaner is disclosed.

[0019] This load-bearing ultrasonic cleaner, hereinafter referred to as "the cleaner", can be placed on dressing tables, desks, dining tables and bedside tables, etc., for cleaning toothbrushes, dentures, braces, jewelry, ornaments, nail clippers, razors, pacifiers, cup lids and contact lenses, etc. It is small in size, has a smooth shape, reliable structure and is easy to use.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The cleaner includes: an externally visible upper flip-top 100, a middle frame 200, and a base 500; a washing tank 310 and a support basket 320 visible after opening the upper flip-top 100; and an internal, invisible inner frame 330 and a barrel-mouth sealing ring 603. The support basket 320, washing tank 310, and inner frame 330 are all barrel-shaped and are fitted together from the inside out. Please refer to... Figure 4 , Figure 5 and Figure 6The base 500 includes a bowl-shaped bottom shell 510, a battery pad 520, a lithium battery 530, an inner support 540, and a main circuit board 550.

[0021] In this cleaner, the middle frame 200 is located at the rim of the bowl-shaped bottom shell 510 of the base 500, with its top edge turned inward and extending horizontally. Support columns 512 on the inner wall of the bowl-shaped bottom shell 510 are used to mount the inner bracket 540. A lithium battery 530 is installed within the space enclosed by the inner bracket 540 and all the support columns 512. The bottom end of the inner frame 330 is supported by two support columns 512, and the rim edge is fitted onto the middle frame 200. The main body of the cleaning tank 310 is suspended, with the rim edge turned outward and sandwiched between the middle frame 200 and the inner frame 330. The inner frame 330, the middle frame 200, and the support columns 512 mitigate the transmission of vibration energy from the cleaning tank 510.

[0022] The specific structure of the cleaner is described below.

[0023] The inner side wall of the bowl-shaped bottom shell 510 is provided with five reinforcing ribs 517 that extend axially and are evenly distributed circumferentially.

[0024] The bowl-shaped bottom shell 510 has four feet 511 on its outer surface and six support columns 512 on its inner wall. Both the feet 511 and support columns 512 are hollow. Each foot 511 has an opening on its bottom surface to accommodate a foot pad 608. Four of the support columns 512 are relatively short and are used to install the inner bracket 540. The remaining two support columns 512 are relatively tall and pass through the two feet 511 respectively to install the inner frame 330. All the support columns 512 are distributed around a virtual rectangle on the inner wall of the bowl bottom, forming a space for the lithium battery 530 together with the inner bracket.

[0025] The side wall of the bowl-shaped bottom shell 510 has a side wall through hole 513. A charging socket is embedded in the side wall through hole 513. This charging socket is a TYPE-C USB socket, which is a common accessory for mobile electronic devices.

[0026] The side wall through hole 513 has a pin hole on its edge for the pin of the plug cap 606 to be inserted. The body of the plug cap 606 can be opened to seal the outside of the side wall through hole 513 to prevent dust or water from entering.

[0027] The lithium battery 530, roughly rectangular or cylindrical in shape, lies horizontally within the area surrounded by six support pillars 512. A battery pad 520 is located between the lithium battery 530 and the inner wall of the bowl-shaped base 510. The battery pad 520 is a polyurethane foam component with sufficient thickness to cushion vibrations from the cleaning tank 310, preventing damage to the lithium battery 530.

[0028] The inner support 540 is a hollow, flat cylindrical shape with an open bottom, its internal space accommodating the lithium battery 530. The sidewalls of the inner support 540 have four protrusions, which are mounted to the tops of four support pillars 512 using screws 703. The inner support 540 surrounds the upper half of the lithium battery 530. The top surface of the inner support 540 lies in a horizontal plane and is used to mount the main circuit board 550.

[0029] The main circuit board 550 is mounted on the horizontal top surface of the inner bracket 540 with screws. The main circuit board 550 includes an MCU chip, a charging circuit (which may include a charging socket), a power supply circuit, a boost circuit, and other electronic components. The main circuit board 550 is electrically connected to the lithium battery 530, the charging socket (not directly soldered), the operation monitoring unit 130 described below, and the transducer 311 described below. Details are standard knowledge in the field of electronics and will not be elaborated upon here.

[0030] With the above structure, the lithium battery 530, the inner support 540 and the main circuit board 550 occupy the lower half of the bowl-shaped bottom shell 510. The lithium battery 530 is located in the space surrounded by the six support columns 512 and the inner support 540, and its assembly is firm, so that the cleaner does not require counterweight.

[0031] The bowl-shaped bottom shell 510 has a bowl-shaped opening for connecting the middle frame 200. The radial inner side of its end face protrudes axially, and its inner wall is provided with a plurality of second fasteners 514.

[0032] The middle frame 200 is a flattened annular column with an inverted L-shaped circumferential cross-section, meaning its top edge is turned inward and extends horizontally. Multiple first fasteners 210 are provided on the inner wall of the bottom end of the middle frame 200, and each first fastener 210 engages with a second fastener 514. The annular bottom surface of the middle frame 200 and the bowl-shaped bottom shell 510 are mutually concave and convex, and a bowl-shaped sealing ring 601 is sandwiched between them.

[0033] The inner frame 330 is barrel-shaped, with most of its body located within the bowl-shaped bottom shell 510, occupying the upper half of the bowl-shaped bottom shell 510, and its top located within the middle frame 200. The lower end of the inner frame 330 has two clearance openings 33b and 33c for accommodating the main circuit board and facilitating the passage of conductive lines. The bottom surface of the inner frame 330 has two radially opposing mating protrusions 332. These two mating protrusions 332 abut against two taller support pillars 512, one-to-one end-to-end. During assembly, screws 704 are inserted from... Figure 4 The indicated support leg 511 enters the support column 712, and then the mating protrusion 332 is fixedly assembled with the support column 712, so that the inner frame 330 is installed on the top of the two support columns 712.

[0034] The screw 704 is fitted with an anti-loosening washer 609. The anti-loosening washer 609 is a polyurethane foam component with sufficient thickness to cushion vibrations from the cleaning tank 310, thereby preventing the screw 704 from loosening.

[0035] The inner frame 330 has a turned-out and horizontally extending edge at the barrel opening, and is assembled with the middle frame 200 through a flange structure. Specifically, a plurality of perforated seats 331 through which bolts can be inserted are provided on the radially outer side of the edge of the barrel opening of the inner frame 330, and the perforated seats 331 are assembled to the top edge of the middle frame 200 by a bolt pair.

[0036] On the radially inner side of the edge of the barrel opening of the inner frame 330, it is used to carry the cleaning tank 310.

[0037] The cleaning tank 310 is barrel-shaped, with a transducer 311 provided at the bottom of the barrel, and the edge of the barrel opening is turned out. Except for the flexible wires at the barrel opening and the bottom (not shown in the drawing), most of the cleaning tank 310 is suspended in the inner frame 330. Specifically, the edge of the barrel opening of the cleaning tank 310 extends horizontally, and the upper side, outer side and lower side are sandwiched by a single barrel opening seal ring 603, and together with the barrel opening seal ring 603, it is clamped between the top edge of the middle frame 200 and the edge of the barrel opening of the inner frame 330.

[0038] That is: the barrel opening seal ring 603 sandwiches the edge of the barrel opening of the cleaning tank 310 from the upper and lower sides, and together with the edge of the barrel opening of the cleaning tank 310, it is clamped between the top edge of the middle frame 200 and the edge of the barrel opening of the inner frame 330, so that its circumferential cross-section is in a U-shape (or an n-shape) after assembly.

[0039] The capacity of the cleaning tank 310 is 350 - 750 ml, and it is used to carry clean water, aqueous solution, ethanol solution or mixed solvent solution.

[0040] The input power adjustment range of the transducer 311 is 30 - 67 W, and the operating frequency adjustment range is 45 - 65 kHz. Thus, suitable power and ultrasonic frequency can be selected to clean different items.

[0041] The rated output power of the lithium battery 530 is 45 W, 55 W, 65 W, 70 W, 80 W, 90 W, or 100 W, and the rated capacity is 5000 mAh, 5500 mAh, 6500 mAh, 7500 mAh, 10000 mAh, 12000 mAh, 15000 mAh, 18000 mAh or 20000 mAh.

[0042] Adopting the above structure, the main body of the cleaning tank 310 is suspended, and is only fixed by assembling the barrel opening, and the edge of the barrel opening is sandwiched on three sides by the barrel opening seal ring 603; compared with using two flat gasket rings, it has a better effect of slowing down the transmission of vibration energy, and can protect the circuit contacts and circuit solder joints of the lithium battery 530 and other components.

[0043] The carrying basket 320 has an open top surface, and an operation handle 321 is provided at the center of the inner wall at the bottom end for putting in and taking out the cleaning tank 310, and feet are provided on the bottom surface to isolate the bottom of the cleaning tank 310.

[0044] With the above structure, the carrying basket 320 can separate the items to be cleaned from the cleaning tank 310, and can be used as a drain basket after cleaning; the centrally located operating handle 321 facilitates the picking and putting of items, and can also separate different items to be cleaned.

[0045] The top cover 100 is hinged to the rear end of the middle frame 200 to cover the top surface of the middle frame 200.

[0046] Please see Figure 7 The flip cover 100 includes a disc-shaped top cover 110 and an operation monitoring unit 130.

[0047] The top surface of the dish-shaped top shell 110 is provided with a top surface groove. This top surface groove consists of a circular groove portion 11a and a wire groove portion 11b. The circular groove portion 11a is located at the center of the top surface of the dish-shaped top shell 110, and the wire groove portion 11b extends radially to the edge of the dish-shaped top shell 110. A wire through hole is provided at the radially outer end of the wire groove portion 11b. Correspondingly, a tadpole-shaped boss 113 is formed on the inner surface of the dish-shaped top shell 110.

[0048] On the radially outer side of the wire groove 11b, the edge of the dish-shaped top shell 110 protrudes downward to form a hinge portion 115. The hinge portion 115 can be embedded into the hinge groove 220 of the middle frame 200. The bottom surface of the hinge groove 220 is provided with another wire through hole 22a. A cable sealing ring 602 is installed on the wire through hole 22a to achieve waterproofing. One side wall of the hinge groove 220 is provided with a blind hole, while the other side wall is provided with a through hole. One end of the hinge shaft passes through the through hole, through the hinge portion 115, and into the blind hole in sequence, thereby hinged the upper cover 100 and the middle frame 200 together. The outer surface opening of the above-mentioned through hole is filled and sealed by an orifice plug 604.

[0049] The operation monitoring unit 130 is embedded in the aforementioned top surface recess and includes a base plate 131, a sub-circuit board 132, a faceplate 134, and three buttons 133. A travel buffer 1331 is provided under the keycap of the button 133 to eliminate keycap noise and buffer keycap travel.

[0050] The substrate 131 includes a circular portion and a tail portion. The tail portion of the substrate 131 is filled with a wire groove 11b. The circular portion of the substrate 131 is shaped like an inverted short barrel and is embedded in a circular groove 11a. The circular portion of the substrate 131 has several through holes, which are installed at the top of four groove bottom protrusions 111 of the circular groove 11a by screws 701. A circular groove sealing ring 605 is provided between the bottom surface of the circular groove 11a and the circular portion of the substrate 131.

[0051] The sub-circuit board 132 is mounted on the bottom surface of the circular portion of the substrate 131 by screws 702. Four ultraviolet disinfection lamps are soldered to the bottom surface of the sub-circuit board, and three buttons 133, multiple LED indicator lights, and a set of LED digital lights are soldered to the top surface. The buttons 133, LED indicator lights, and LED digital lights are respectively embedded in the through holes of the substrate.

[0052] The ribbon cable 1328 of the sub-circuit board 132 extends into the wire groove 11b, passes through the wire through hole and the ribbon cable sealing ring 602 at the radially outer end, and enters the base to connect to the main circuit board 550.

[0053] Each UV disinfection lamp faces a bottom through-hole 112 located in the circular groove of the top surface. A quartz glass plate 122 is embedded in the bottom through-hole 112 and is attached to the UV disinfection lamp by adhesive tape 121. The emitted light from the UV disinfection lamp can pass through the adhesive tape 121 and the quartz glass plate 122 to disinfect the cleaning tank 310 and the items to be cleaned. Because of the obstruction of the adhesive tape 121, the liquid in the cleaning tank 310 will not penetrate through the bottom through-hole 112.

[0054] The face mask 134 is a flexible and semi-transparent PET sheet that is sealed and covers the top surface of the circular portion of the substrate 131. Through the face mask 134, the button 133 can be pressed, and the display information of the LED indicator and LED digital lights can also be observed.

[0055] A magnetic base 114 is provided on the inner side (i.e., bottom surface) of the front edge of the disc-shaped top cover 110. The magnetic base 114 has a blind hole, in which a permanent magnet 118 is embedded. A blind hole buffer pad 610 is provided at the opening of the blind hole. A Hall sensor is provided on the front edge of the middle frame 200. The permanent magnet 118 is used to magnetically attract the middle frame 200 and trigger the Hall sensor, and the buffer pad 610 is used to reduce closing noise. The Hall sensor is electrically connected to the main circuit board 550 and sends a sensing signal to the microprocessor chip (MCU) of the circuit board 550 when the top cover is opened and closed.

[0056] With the above structure, the operation monitoring unit 130, transducer 311, lithium battery 530, charging socket, and Hall sensor are electrically connected to the main circuit board 550. The magnetic base 114 and the Hall sensor form a proximity switch. When the upper cover 100 is closed, the main circuit board 550 can promptly turn on the transducer 311 and the ultraviolet disinfection lamp based on the sensing signal from the Hall sensor, thereby simplifying the operation procedure. When the upper cover 100 is opened, the main circuit board 550 can promptly turn off the working transducer 311 and the ultraviolet disinfection lamp based on the sensing signal from the Hall sensor, thereby saving energy and reducing accidental injury.

[0057] The washer has plastic seals at all seams and openings connecting the inside and outside, resulting in low noise and meeting IPX7 waterproof standards. These plastic seals include, but are not limited to: a faceplate 134, a bowl-shaped sealing ring 601, a cable sealing ring 602, a bucket-shaped sealing ring 603, an opening plug 604, a circular groove sealing ring 605, a stopper cap 606, foot pads 608, anti-loosening gaskets 609, and blind hole buffer pads 610.
