[0021] Example One An ultrasonic atomization device 100 for handheld use is disclosed.

[0022] The ultrasonic atomization device 100 can be used for inhalation administration in clinical, home, and travel. The acquisition and use of the device must strictly comply with medical prescriptions and medical advice, as well as the laws and regulations of the region.

[0023] Please refer to Figure 1a , Figure 1b , Figure 1c , Figure 2 and Figure 6 , the ultrasonic atomization device 100 is composed of an electronic control unit 10, a liquid storage unit 20, and an atomization unit 30. The combination of the liquid storage unit 20 and the atomization unit 30 is called an atomization head 40.

[0024] Figure 2The direction of the central axis F of the atomizing unit 30 and its parallel direction are collectively referred to as the axial direction.

[0025] The atomizing unit 30 includes a connecting cylinder 31 and an ultrasonic atomizer 35, and has a flow channel extending along the central axis F to facilitate the inflow of liquid matrix and the outflow of aerosol. The outer section of the connecting cylinder 31 is configured as a fifth connecting part 105, and the edge of the inner section of the connecting cylinder 31 is configured as a first connecting part 101. The ultrasonic atomizer 35 is mounted on the port of the inner section of the connecting cylinder 31. The bottom of the liquid storage unit 20 is configured as a second connecting part 102, the top is configured as a liquid storage chamber 20a, and the side is provided with a third connecting part 103. The bottom of the liquid storage chamber 20a is provided with a liquid outlet channel 212. The side of the electronic control unit 10 is provided with a viewing window 111 and a switch button 112, the interior is provided with a battery compartment 115 and an electronic control board 118, and the top is configured as a fourth connecting part 104.

[0026] One, but not unique, assembly process of the ultrasonic atomizing device 100 includes: (1.1) the first connecting part 101 is mechanically connected to the third connecting part 103 along the axial direction, while the ultrasonic atomizer 35 is connected to the liquid outlet channel 212 in the axial direction, that is, the atomizing head 40 is first assembled; (1.2) the second connecting part 102 is mechanically connected to the fourth connecting part 104 along the axial direction, while the ultrasonic atomizer 35 is electrically connected to the fourth connecting part 104 in the axial direction.

[0027] One, but not unique, disassembly process of the ultrasonic atomizing device 100 includes: (2.1) pressing the unlock button 126 to unlock the atomizing head 40, and simultaneously pulling the electronic control unit 10 backward along the axial direction, i.e., separating the electronic control unit 10 from the atomizing head 40 to de-energize the ultrasonic atomizer 35; (2.2) rotating the connecting cylinder 31 to unlock the atomizing unit 30, and then disassembling the atomizing unit 30 and the liquid storage unit 20 along the central axis F; (2.3) if necessary, disassembling the ultrasonic atomizer 35 from the connecting cylinder 31.

[0028] Using the above structure, the atomizing head 40, liquid storage unit 20, atomizing unit 30, ultrasonic atomizer 35, and connecting cylinder 31 can all be cleaned, disinfected, and dried independently. The following mainly introduces the modular structure; other aspects can be found in commercially available ultrasonic atomizing equipment.

[0029] Please continue reading. Figure 2 The electronic control unit 10 includes a first housing 11 and a fourth connecting part 104.

[0030] The first housing 11 is ergonomically designed for hand grip and is shaped like a slightly curved column. The bottom of the first housing 11 is open and closed by a bottom cover 113, which houses a battery compartment 115. A charging socket 114 is located between the lower rear side of the first housing 111 and the battery compartment 115. A viewing window 111 and a power button 112 are located on the front side of the first housing 111. An elastic support 1131 is provided on the inner wall of the bottom cover 113, which abuts against the battery compartment 115 to prevent accidental opening. A rechargeable battery 116 is installed inside the battery compartment 11, and an electronic control board 118 is attached to its front side. The on / off state of the electronic control board 118 is controlled by the power button 112, and a display module 117 on the electronic control board 118 faces the viewing window 111. The electronic control board 118 is electrically connected to the rechargeable battery 116 via wires and also electrically connected to a power connector 123 located on the top surface of the first housing 11 via wires.

[0031] Please see Figure 3a , Figure 3b and Figure 4 The fourth connection part 104 includes a cover, two first latches 1221, an electrical connector 123, a locking latch 124, and an unlocking button 126.

[0032] The aforementioned housing consists of a front housing 121 and a rear housing 122. The front housing 121 and the rear housing 122 engage with each other via a convex-concave mechanism at their junction. The rear housing 122 occupies a larger proportion of the side with the engagement junction. The aforementioned housing is fastened to the top surface of the first housing 11 with its opening facing downwards, and is secured by two screws 1203.

[0033] The junction between the top surface and the front side of the front shell 121 is recessed, thereby forming a clearance groove 1211 that fits the liquid outlet channel 212. The shape of the clearance groove 1211 is adapted to the liquid outlet channel 212 to avoid the liquid outlet channel 212.

[0034] The top surface of the rear cover 122 is provided with a top surface through hole 122b. The top surface through hole 122b allows the locking tongue 1244 to pass through in order to lock the atomizing head 40.

[0035] Each of the left and right sides of the rear cover 122 is provided with a first fastening element 1221, which is a convex strip extending in the axial direction. That is, two first fastening elements 1221 are strips extending in the axial direction and are respectively provided on the left and right sides of the cover.

[0036] The unlock button 126 is roughly n-shaped, including a pressing part 1261 and two transmission parts 1262, which are embedded in a blind hole 122a located on the rear side of the rear housing 122. The pressing part 1261 is partially exposed in its free state for pressing operation. Both transmission parts 1262 are strip-shaped, with a wedge-shaped limiting member 1263 at their base. Their ends pass through the bottom through-hole of the blind hole 122a, and the gap between them accommodates a spring 1202. One end of the spring 1202 is embedded in the blind hole on the inner side of the pressing part 1261, and the other end abuts against the bottom surface of the blind hole 122a. In other words, the unlock button 126 is axially movable and elastically reset, embedded in the housing, including the pressing part 1261 exposed on the rear side of the housing and the transmission parts 1262 extending into the housing.

[0037] The locking element 124 is generally a U-shaped block. A guide ridge 1241 is provided on each of the left and right sides of the locking element 124 to allow for vertical axial sliding. The top surface of the locking element 124 (i.e., the top surface of the U-shaped head) has a latch 1244 that protrudes from the top surface through-hole 122b to lock the atomizing head 40. The top front side of the latch 1244 is set with a slope 1245 so that the atomizing head 40 presses the latch 1244 into the top surface through-hole 122b during insertion. The middle part of the locking element 124 (i.e., the shoulder of the U-shaped head) has two slopes 1243 that abut (i.e., connect) two transmission parts 1262. The bottom surface of the locking element 124 has a blind hole for mounting one end of a spring 1201. The other end of the spring 1201 is located within the blind hole on the top surface of the first housing 11. That is, the locking element 124 is installed inside the housing in a vertically axially movable and elastically reset manner.

[0038] With the above structure, when the unlock button 126 is pressed from the outside, the transmission part 1262 will press down the inclined surface 1243, causing the locking tongue 1244 to retract into the top surface through hole 122b. After the unlock button 126 is released, driven by the springs 1201 and 1202, the unlock button 126 and the locking fastener 124 return to their initial positions. Thus, in the free state, the locking tongue 1244 protrudes from the top surface through hole 122b and engages with the blind hole 21b of the liquid storage unit 20.

[0039] The electrical connector 123 includes a power supply circuit board, a pair of spring-loaded power supply electrodes 1231, and a spring-loaded ground electrode 1233. The power supply circuit board is fixedly mounted inside the front housing 121. The two power supply electrodes 1231 protrude from the front side of the front housing 121 below the clearance groove 1211. The ground electrode 1233 protrudes from the front housing 121 at the center of the clearance groove 1211. That is, the power supply circuit board is fixedly mounted inside the housing, the power supply electrodes 1231 protrude from the housing below the clearance groove 1211, and the ground electrode 1233 protrudes from the housing at the center of the clearance groove 1211.

[0040] Please see Figure 5a andFigure 5b The liquid storage unit 20 includes a second housing 21, a hinged top cover 22, and a side wall cylinder 24.

[0041] The second housing 21 is an L-shaped, transparent PC (polycarbonate) component.

[0042] The upper part of the second housing 21 is a liquid storage chamber 20a. The top opening of the liquid storage chamber 20a is sealed by a hinged top cover 22. The edge of the top cover 22 is provided with a hinged annular buckle 221, and the top cover 22 is locked to the opening of the liquid storage chamber 20a by the annular buckle 221. The bottom edge of the inner wall of the liquid storage chamber 20a is recessed and open, thereby forming a liquid outlet channel 212.

[0043] The lower part of the second housing 21 has a bottom groove 21a with open bottom and rear sides, serving as a second connecting part 102. The top wall of the bottom groove 21a corresponds to the bottom surface of the liquid storage tank 20a. The top wall of the bottom groove 21a has a blind hole 21b to accommodate the locking tongue 1244 protruding from the cover. The two side walls 211 of the bottom groove 21a are configured to match the two sides of the cover, and have a second fastening member 21c in the shape of a strip groove. The second fastening member 21c is used to accommodate the first fastening member 1221. The front side wall of the bottom groove 21a has three electrode through holes 21e. Two electrode through holes 21e are used to accommodate the ends of the two power supply electrodes 1231, and the remaining electrode through hole 21e allows the grounding electrode 1233 to pass through.

[0044] The upper and lower parts of the second housing 21 form a slightly curved column that is easy to grip. The front side of the column is integrally provided with a side wall cylinder 24 that protrudes outward in the axial direction, and also has a liquid outlet port 218 directly opposite the center of the side wall cylinder 24.

[0045] The inner end of the sidewall cylinder 24 surrounds three electrode through holes 21e and a liquid outlet 218. The liquid outlet 218 is concentrically arranged with the sidewall cylinder 24, that is, the central axis of the sidewall cylinder 24 passes through the center of the liquid outlet 218. In an axial view, the electrode through hole 21e corresponding to the ground electrode 1233 is located inside the liquid outlet 218, while the remaining two electrode through holes 21e are located below the liquid outlet structure 128.

[0046] The liquid outlet 218 serves as the outer opening of the liquid outlet channel 212 and, together with the side wall cylinder 24, belongs to the third connection part 103. The end of the grounding electrode 1233 extends into the liquid outlet channel 212 to contact the liquid matrix.

[0047] The outer end of the sidewall cylinder 24 is provided with two radially opposite third fasteners 24b. Both third fasteners are L-shaped. Each third fastener 24b includes a guide groove located at the edge of the sidewall cylinder 24 and a locking hole located inside the guide groove.

[0048] That is, the third connecting part 103 includes a side wall cylinder 24 and a liquid outlet 218. The inner end of the side wall cylinder 24 is connected to the side wall of the liquid storage unit 20 and surrounds the three electrode through holes 21e. The outer end of the side wall cylinder 24 is provided with two third fasteners 24b. The liquid outlet 218 of the liquid outlet channel 212 is provided on the side wall of the liquid storage unit 20, located above the two electrode through holes 21e and at the center of the side wall cylinder 24.

[0049] Please see Figure 6 , Figure 7a and Figure 7b The atomizing unit 30 is basically symmetrical about the central axis and includes a connecting cylinder 31, an ultrasonic atomizer 35, and a cylinder cap 38. The ultrasonic atomizer 35 is basically symmetrical about the central axis and includes the following components, all of which are annular: a first annular shell 351, a sealing gasket ring 352, a transducer assembly 353, a second annular shell 354, and a base 355.

[0050] The circumferential sidewall of the second annular shell 354 is embedded in the first annular shell 351, thereby forming a flat annular cylindrical protective shell. This protective shell is mounted on the base 355, and the main bodies of the transducer assembly 353 and the sealing gasket ring 352 are located inside the protective shell.

[0051] The connecting tube 31 is cylindrical and serves as an aerosol output channel, connecting the mouthpiece (or breathing mask) and the ultrasonic nebulizer 35 during use. The inner and outer sections of the connecting tube 31 are transitioned by a step 311, with the inner section being thicker than the outer section and the outer section being longer than the inner section, thus forming the main body of the connecting tube 31.

[0052] The inner side of the connecting cylinder 31, as the first connecting part 101, is provided with a pair of fourth fasteners 313 that are radially opposite to each other and in the shape of outward protrusions for engaging the third fastener 24b.

[0053] The outer end of the connecting tube 31, serving as the fifth connecting part 105, has anti-slip textures 316 on its side for mounting the tube cap 38, mouthpiece, or breathing mask. This outer end has two sets of air vents 31a adjacent to the step 311 and radially opposite, as well as two sets of anti-slip elements 312 radially opposite and adjacent to the step 311. When the user inhales, air enters the connecting tube 31 through the air vents 31a and mixes with the drug-containing atomized droplets to form an aerosol, which can directly enter the lungs. The anti-slip elements 312 are used to accept twisting operations. Instructional patterns 314 guiding the twisting operation are printed or engraved on the outer surface of the connecting tube 31.

[0054] The connecting cylinder 31 has a dome-shaped, annular connector 315 inside. The center of the annular connector 315 protrudes from the inner end face of the connecting cylinder 31 to allow for the rotatable mounting of the ultrasonic atomizer 35. Multiple ribs 317 are provided between the annular connector 315 and the inner wall of the connecting cylinder 31.

[0055] The ultrasonic atomizer 35 is mounted on the inner section port of the connecting tube 31. (See also...) Figure 2 and Figure 7b The central hole wall 3552 of the base 355 is truncated cone-shaped and mates with the central part of the annular connector 315. Thus, the ultrasonic atomizer 35 is detachably and rotatably fitted onto the central part of the annular connector 315 via the base 355.

[0056] Please see Figure 10 The outer radial edge of the base 355 is provided with four axially extending rings 3551 for engaging the first annular shell 351. The inner side of the base 355 is provided with four circumferentially distributed blind holes 355b, and also with two protrusions 3553 located at the bottom end.

[0057] Please see Figure 9 The central hole of the first annular shell 351 is approximately elliptical, with its minor axis d1 slightly shorter than its major axis d2. At the bottom end of the first annular shell 351, there are two electrode through holes 351b for the insertion part 3525 of the sealing gasket ring 352 to be inserted.

[0058] The outer surface of the sidewall of the first annular shell 351 has four circumferentially distributed protrusions 3511 and a positioning strip 3513. The four protrusions 3511 can be engaged one-to-one with the four rings 3551 of the base 355. The positioning strip 3513 extends axially and is used to engage with a positioning groove located on the inner wall of the sidewall cylinder 24; thus, the ultrasonic atomizer 35 must be angularly aligned and not rotated when assembled and disassembled, which can better protect the two receiving electrodes 3531 of the transducer assembly 353.

[0059] The inner surface of the side wall of the first annular shell 351 is provided with a positioning protrusion 3515 located between two electrode through holes 351b, so as to cooperate with the edge notch 352d of the sealing gasket ring 352.

[0060] The bottom inner wall of the first annular shell 351 is provided with four circumferentially distributed permanent magnets 357. By using permanent magnets 357, the ultrasonic atomizing unit 10 can magnetically attract the second shell 21, which also has permanent magnets embedded in it (not shown in the figure), thus ensuring stable assembly.

[0061] The bottom surface of the inner wall of the first annular shell 351 is also provided with four circumferentially distributed protrusions 3512. These four protrusions 3512 pass through the sealing gasket ring 352 and the second annular shell 354 in sequence, and finally insert into the four blind holes 355b on the inner side of the base 355.

[0062] Please see Figure 7a , Figure 8a and Figure 8bThe ultrasonic nebulizer 35 includes only one sealing ring 352. The sealing ring 352 includes a liquid receiving interface 3521, a neck 3522, an annular pad portion 3523 and an annular notch portion 3524 distributed sequentially along the axial direction, and also includes two insert portions 3525.

[0063] Between the bottom end of the annular pad portion 3523 and the two ends of the annular notch portion 3524, there are two electrode through holes 352c and a centrally located edge notch 352d. Each electrode through hole 352c is configured as an insert portion 3525 facing the opening edge of the liquid receiving interface 3521. The insert portion 3525 is inserted into the electrode through hole 351b of the first annular shell 351. The edge notch 352d is fitted onto the positioning protrusion 3515 of the first annular shell 351.

[0064] The sealing gasket ring 352 has four through holes 352b that pass through the annular gasket portion 3523 and the annular notch portion 3524. These four through holes 352b allow the four protrusions 3512 of the first annular shell 351 to pass through one by one.

[0065] The receiving interface 3521 is located outside the central hole of the first annular shell 351 and is used to sealably connect to the liquid outlet interface 218 along the axial direction, so that the material flow channel of the atomizing unit 30 is connected to the liquid outlet channel 212 of the liquid storage unit 20.

[0066] The annular gasket 3523 and the annular notch 3524 are located inside the first annular shell 351, with the annular notch 3524 abutting against the bottom inner wall of the second annular shell 354. The annular gasket 3523 completely covers the bottom inner wall of the first annular shell 351, axially isolating the first annular shell 351 and the second annular shell 354, thus mitigating the impact from the first annular shell 351 and the liquid receiving interface 3521. With this structure, the sealing gasket ring 353 not only has a sealing function but also mitigates the pressing impact caused by combined operation, effectively protecting the transducer assembly 353.

[0067] Most of the transducer assembly 353 is sealed within a protective housing, including a microporous mesh, an annular piezoelectric plate attached to the microporous mesh, and two receiving electrodes 3531 welded to the annular piezoelectric plate. The central portion of the microporous mesh is exposed in the material flow channel. Both receiving electrodes 3531 are rod-shaped, with their ends passing through electrode through holes 352c and 351b, and exiting the first annular housing 351 from below the central hole of the first annular housing 351.

[0068] Two receiving electrodes 3531 are used for axially electrically connecting the fourth connection portion 104 of the electronic control unit 10. Specifically, the ends of the two receiving electrodes 3531 are inserted into the electrode through holes 21e of the second housing 21, and axially contact the two power supply electrodes 1231 in the electrode through holes 21e; ​​the other end face of each receiving electrode 3531 contacts the end face of a protrusion 3553 of the base 355, thereby ensuring structural stability during insertion.

[0069] In summary, the ultrasonic atomizer 35 is basically symmetrical about its central axis and has a material flow channel extending along the central axis F for the inflow of liquid matrix and the outflow of aerosol, including the following sequentially distributed components along the central axis F: A base 355, in the form of a ring, is for detachable mounting on one port of the connecting cylinder 31; A protective shell, in the shape of a flat ring cylinder, is mounted on the base 355; A sealing ring 352, the main body of which is located inside the protective shell, with a portion extending through the central hole of the protective shell to form a liquid receiving interface 3521; and A transducer assembly 353 is mostly sealed inside a protective shell, including a microporous mesh, an annular piezoelectric sheet attached to the microporous mesh, and two receiving electrodes 3531 welded to the annular piezoelectric sheet. The center of the microporous mesh is exposed in the material flow channel, and the ends of the two receiving electrodes 3531 protrude from the side of the protective shell with a liquid receiving interface 3521.

[0070] With the above structure, (1) the ultrasonic atomizer 35, and the atomizing unit 30, atomizing head 40 and ultrasonic atomizing device 100 including the ultrasonic atomizer 35 can be disassembled as needed for cleaning, disinfection and drying; (2) the ultrasonic atomizer 35 has only one sealing gasket ring, but it can better protect the ring energy component and the receiving electrode, and is convenient to assemble and use.

[0071] In another embodiment, the liquid receiving interface is a separate component, and the sealing gasket does not protrude from the first annular shell 351. There may be two sealing gaskets, one in front of the other, which together form a resilient soft inner shell protecting the transducer assembly.

[0072] In another embodiment, the piezoelectric element of the ultrasonic atomizer is not passed through the flow channel; the liquid matrix is ​​fed radially symmetrically via capillary material on one side toward the outer section of the connecting cylinder. Although the flow channel has necessary bends, it extends substantially along the axial direction of the atomizing unit.

[0073] In other embodiments, the electronic control unit has only a touch screen without buttons, or vice versa.

[0074] In other embodiments, the base and connecting cylinder are integral and cannot rotate relative to each other, and the end of the power supply electrode is a ball-bearing type. The corresponding latching structure is unlocked and locked by operating the button or ring buckle, and then the atomizing unit is rotated as a whole, so that the power supply electrode and the power receiving electrode finally come into axial head-to-head contact (i.e., electrical connection).

[0075] The configuration of the interlocking snap-fit ​​structure is easily understood.

[0076] Please note that the manufacture, transportation, sale, and supply of medical ultrasonic nebulization equipment and related medications must comply with the laws and regulations of the region. For example, prominent text and images should be used to warn of drug abuse risks, and fingerprint recognition, measurement, and statistical functions should be employed to reduce medication errors.

[0077] The above embodiments, application examples, and technical analyses are intended to introduce the technical concept and features of this application, enabling those skilled in the art to implement the technical solutions of this application, and do not constitute a limitation on the scope of protection claimed. Simple modifications and equivalent transformations to the embodiments are all within the above-mentioned scope of protection.
