Description

[Technical Field]

[0001] The present application relates to the technical field of atomizers, and more particularly to a handheld atomizer and an atomizing sheet module applied thereto. [Background technology]

[0002] Atomizers are widely used as home medical devices for the drug treatment of respiratory diseases. The atomizing sheet, the core component of the atomizer, is prone to limescale buildup and drug crystallization when in contact with the drug solution over a long period of time, which can clog the nozzle passage where the atomizing sheet is installed, significantly reducing atomization efficiency and necessitating replacement of the atomizing sheet.

[0003] Most existing atomizing sheets are welded directly to the mouthpiece by the top needle, and waterproof silicone is provided around the atomizing sheet to make it waterproof, so under normal circumstances, the atomizing sheet cannot be removed and replaced.

[0004] Furthermore, in some cases, the nozzle and atomizer body of an existing atomizer are connected using a screw fastening system. When the atomizing sheet becomes clogged, users must use a special tool to remove and replace the nozzle, a complicated and time-consuming operation process that prevents users from performing maintenance themselves, often forcing them to repair or replace the device. At the same time, the screws are prone to rust over time, causing parts to stick, affecting the normal operation of the device and posing a safety risk. Furthermore, screw tightening and wiring welding processes are required during production, which is complex and reduces production efficiency. In still other cases, the nozzle and atomizer body are integrated into one structure. In these cases, users are unable to perform maintenance themselves.

[0005] Therefore, it is necessary to provide a handheld atomizer and an atomization sheet module applicable thereto that allow for easy replacement of the internal atomization sheet and easy removal and maintenance. Summary of the Invention [Problem to be solved by the invention]

[0030] In order to describe the technical solutions of the present application more clearly and completely, the present application will be further described below with reference to the drawings.

[0031] Please refer to FIGS. 1 and 2. A handheld nebulizer 1000 with an easily replaceable nebulizing sheet module according to the present application includes a control handle 1 and an nebulizing assembly 2. The control handle 1 is used to supply power to the nebulizing assembly 2. The nebulizing assembly 2 is detachably connected to one end of the control handle 1. The nebulizing assembly 2 includes a cup 21, an nebulizing sheet module 22, and a nozzle 23. One end of the cup 21 is detachably and electrically connected to one end of the control handle 1. The cup 21 stores a liquid medicine and supplies the liquid medicine to the nebulizing sheet module 22. The nebulizing sheet module 22 is fixedly connected to one side of the cup 21 via a nozzle 23. The nozzle 23 is detachably connected to one side of the cup 21 and communicates with the nebulizing sheet module 22. The nozzle 23 is connectable to an external mask 3, making the device easy to use for the user. The nebulizing sheet module 22 is electrically connected to the cup 21. In use, the atomizing sheet module 22 atomizes the liquid medicine supplied from the medicine cup 21 and then sprays it from the nozzle 23.

[0032] In this embodiment, the control handle 1 and the nebulizing assembly 2 are combined using a detachable connection or quick release method, making it easy to remove and replace the nebulizing assembly 2. At the same time, to replace the nebulizing sheet module 22 in the nebulizing assembly 2, first remove the nozzle 23 from the cup 21, then remove the nebulizing sheet module 22 from the cup 21. After replacing the nebulizing sheet module 22 with a new one, return it to the cup 21 and secure the nebulizing sheet module 22 with the nozzle 23. After securing the nebulizing sheet module 22, it is electrically connected to the control handle 1 via the cup 21. This completes the nebulizing sheet module 22 replacement process, which is simple and quick.

[0033] As described above, the handheld nebulizer 1000 with easily replaceable nebulization sheet module according to the present invention allows the nebulization sheet inside to be easily replaced, and removal and maintenance can be easily performed.

[0034] As shown in Figures 3, 7, and 9, in this embodiment, a connecting tube 211 is provided on the outer wall 210 of the medicine cup 21. The atomizing sheet module 22 is housed in the connecting tube 211, and the nozzle 23 is engaged with and abuts against the atomizing sheet module 22. The connecting tube 211 extends outward, facilitating quick positioning and installation of the atomizing sheet module 22 and the nozzle 23. To replace the atomizing sheet module 22, simply remove the nozzle 23 from the connecting tube 211, remove and replace the atomizing sheet module 22, then insert the nozzle 23 back into the connecting tube 211. The replacement and crimping of the atomizing sheet module 22 are then completed. A sealing cover 215 is rotatably attached to the top of the medicine cup 21 to seal the top of the medicine cup 21, making it easy for the user to open the cover and pour the medicine into the medicine cup 21.

[0035] In this embodiment, a mounting recess 2111 is provided inside the connecting tube 211, and the atomizing sheet module 22 and the nozzle 23 are both accommodated in the mounting recess 2111, with the outer wall 230 of the nozzle 23 engaging with the inner wall of the mounting recess 2111. The mounting recess 2111 provides a mounting passage with a positioning function for the installation of the atomizing sheet module 22 and the nozzle 23, which helps to improve installation efficiency.

[0036] In this embodiment, at least two locking bosses 21111 (see FIG. 7) are provided on the inner wall of the mounting recess 2111, and at least two L-shaped locking grooves 231 (see FIG. 9) are provided on the outer wall 230 of the nozzle 23. Specifically, in this embodiment, the nozzle 23 includes a nozzle portion 233 located on the front end side and a nozzle cover 235 located at the rear end close to the atomizing sheet module 22, and at least two L-shaped locking grooves 231 are provided on the outer wall of the nozzle cover 235. The at least two L-shaped locking grooves 231 and the at least two locking bosses 21111 correspond one-to-one, and the locking bosses 21111 are received in the L-shaped locking grooves 231. When attaching the nozzle 23, the nozzle cover 235 of the nozzle 23 is inserted into the mounting recess 2111, and then the openings 2311 of the L-shaped locking grooves 231 are aligned with the locking bosses 21111 before insertion. As a result, the locking boss 21111 slides along the L-shaped locking groove 231, and then the nozzle 23 is rotated to slide the locking boss 21111 to the end of the L-shaped locking groove 231, completing the engagement and connection between the nozzle 23 and the connecting tube 211.

[0037] In this embodiment, a first positive and negative electrode conductive needle 2112 is provided on the bottom wall of the connecting tube 211, and one side of the atomizing sheet module 22 is electrically connected to the first positive and negative electrode conductive needle 2112. The first positive and negative electrode conductive needle 2112 is divided into two conductive needles, a positive electrode conductive needle and a negative electrode conductive needle. Each of the two conductive needles contacts one side of the atomizing sheet module 22, forming a contact-type electrical connection. Because electricity is required for the atomizing sheet module 22 to nebulize the medicinal liquid, after the atomizing sheet module 22 is inserted into the mounting recess 2111 and fixed by the nozzle 23, the atomizing sheet module 22 is electrically connected to the first positive and negative electrode conductive needle 2112, ensuring normal operation of the atomizing sheet module 22.

[0038] As shown in Figures 7, 10, and 11, in this embodiment, the atomizing sheet module 22 includes a protective case 221, a silicone sealed case 222, an atomizing sheet 223, and a flexible circuit board 2231. The atomizing sheet 223 is fixedly housed within the silicone sealed case 222, which in turn is fixedly housed within the protective case 221. One side of the silicone sealed case 222 is closely connected to and communicates with the medicine cup 21. The atomizing sheet 223 includes an atomizing sheet main body 2230 and a flexible circuit board 2231 located on one side of the atomizing sheet main body 2230. The flexible circuit board 2231 is electrically connected to the atomizing sheet main body 2230 and forms a contact-type electrical connection with the first positive and negative electrode conductive top needle 2112. The protective case 221 is divided into a main shell and an auxiliary shell. The main shell and auxiliary shell collectively clamp and fix the silicone sealed case 222. The silicone sealing case 222 is also divided into a main case and a sub-case. The main case and sub-case jointly clamp and fix the atomizing sheet 223, while enhancing the waterproof sealing effect for the flexible circuit board 2231 and preventing water mist from entering the flexible circuit board 2231. The protective case 221, silicone sealing case 222, and atomizing sheet 223 are combined into an integrated structure, making replacement easy. Positive and negative electrical contacts 22311 are provided on the side walls of the flexible circuit board 2231. When the atomizing sheet module 22 is inserted into the mounting recess 2111, the positive and negative electrical contacts 22311 come into contact with the first positive and negative conductive top needles 2112, forming a contact-type electrical connection. This allows the flexible circuit board 2231 to be electrically connected to the atomizing sheet body 2230, eliminating the need for wiring and welding during assembly, improving assembly convenience, reducing contact resistance, and improving electrical reliability. When atomization is performed, the control handle 1 sends an atomization command to the flexible circuit board 2231, which then controls the current to be supplied to the atomization sheet main body 2230. The atomization sheet main body 2230 then vibrates at high frequency to atomize the liquid medicine flowing from the medicine cup 21.

[0039] As shown in Figures 5 and 8, in this embodiment, a liquid drop tank 212 is provided on one side of the medicine cup 21, and a liquid inlet 22211 is provided on one side of the silicone sealed case 222. The liquid inlet 22211 is aligned with the atomizing sheet 223. The liquid drop tank 212 is in communication with the liquid inlet 22211. The medicinal liquid is contained in the medicine cup 21, passes through the liquid drop tank 212, flows into the liquid inlet 22211, and then comes into contact with the atomizing sheet 223. The high-frequency vibration of the atomizing sheet 223 causes the medicinal liquid to be atomized.

[0040] In this embodiment, a liquid level sensor 2121 is provided inside the liquid drop chamber 212 and is electrically connected to the control handle 1. The control handle 1 is provided with a conductive contact 102. The conductive contact 102 is electrically connected to the main control circuit board 13 inside the control handle 1. The liquid level sensor 2121 makes contact with the conductive contact 102 to form an electrical connection. The liquid level sensor 2121 is used to detect the presence or absence of liquid medicine in the liquid drop chamber 212. If liquid medicine is present in the liquid drop chamber 212, the liquid level sensor 2121 sends a signal indicating "liquid medicine present" to the main control circuit board 13 inside the control handle 1. If liquid medicine is not present in the liquid drop chamber 212, this means that there is no liquid medicine in the cup 21, and the liquid level sensor 2121 sends a signal indicating "no liquid medicine" to the main control circuit board 13 inside the control handle 1. Therefore, when liquid medicine needs to be atomized, the user can operate the start button 1222 on the control handle 1 to send an atomization command to the main control circuit board 13. When the main control circuit board 13 receives a signal indicating "liquid medicine present" from the liquid level sensor 2121, it outputs a control signal to the flexible circuit board 2231, causing the flexible circuit board 2231 to output a current to the atomizing sheet 223. This activates the atomizing sheet 223, atomizing the liquid medicine that has flowed into the atomizing sheet 223. When the main control circuit board 13 receives a signal indicating "no liquid medicine" from the liquid level sensor 2121, even if the user triggers the activation button 1222 on the control handle 1, the main control circuit board 13 does not output a control signal to the flexible circuit board 2231, and the atomizing sheet 223 does not activate. This prevents the atomizing sheet 223 from operating when there is no liquid medicine.

[0041] Please also refer to Figure 6. In this embodiment, one end of the cup 21 is provided with a conductive contact 213, which is electrically connected to the first positive and negative electrode conductive pin 2112. One end of the control handle 1 is provided with a second positive and negative electrode conductive pin 11, which is electrically connected to the conductive contact 213. The second positive and negative electrode conductive pin 11 includes two conductive pins, a positive electrode conductive pin and a negative electrode conductive pin. The two conductive pins respectively contact the two conductive contacts on the conductive contact 213 to form a contact-type electrical connection. A clamping chamber 214 is provided at one end of the cup 21, and a slide rail 101 (see Figure 1) is provided at one end of the control handle 1, which is housed in the clamping chamber 214. The second positive and negative electrode conductive pin 11 is located on one side of the slide rail 101. When the medicine cup 21 needs to be assembled to the control handle 1, the clamping chamber 214 and the slide rail 101 are aligned, and then the slide rail 101 is inserted laterally into the clamping chamber 214 and fixed. After the medicine cup 21 is fixed, the second positive and negative electrode conductive top needles 11 and the conductive contacts 213 form a contact-type electrical connection.

[0042] See Figures 4 and 12. In this embodiment, the control handle 1 includes a grip case 12, a main control circuit board 13, a display 14, and a battery 15. The main control circuit board 13 and the battery 15 are both mounted inside the grip case 12.

The main control circuit board 13 is electrically connected to the display 14, the battery 15, the nebulizing assembly 2, the liquid level sensor 2121, and the second positive and negative conductive tip 11. The battery 15 is a rechargeable battery, such as a rechargeable lithium battery, and is charged by connecting it to an external power source via the main control circuit board 13. During use, the display 14, under the control of the main control circuit board 13, displays information such as the remaining charge of the battery 15, the operating position of the nebulizing assembly 2, and the presence or absence of medicinal liquid in the liquid drop tank 212. The grip case 12 includes a first shell 121, a second shell 122, and a bottom case 123. The first shell 121 and the second shell 122 are arranged symmetrically. The main control circuit board 13, the display 14, and the battery 15 are all arranged between the first shell 121 and the second shell 122. One side of the display 14 is flush with one side of the second shell 122. The bottom case 123 is fixedly connected to the bottoms of the first shell 121 and the second shell 122. A plurality of connection ports 1211 are formed on the surface of the first shell 121. A sealing member 1221 is provided on the edge of the second shell 122. The sealing member 1221 is arranged to correspond to the connection ports 1211 and seals the connection ports 1211. A screw hole 1231 is formed on the surface of the bottom case 123. Threaded posts are provided on the inner walls of both the first shell 121 and the second shell 122. The bottom case 123, the first shell 121, and the second shell 122 are fixed together by screwing the screw holes 1231 into the screw posts.

[0043] In other embodiments, the bottom case 123, the first shell 121, and the second shell 122 may be fixed in other ways, such as by an engagement method.

[0044] In this embodiment, the connection port 1211 and the sealing member 1221 position the connection between the first shell 121 and the second shell 122 and seal the joint. Furthermore, when a user grips the grip case 12, the sealing member 1221 improves the user's grip and increases the frictional force during gripping. The screw holes 1231 and threaded posts allow the first shell 121, the second shell 122, and the bottom case 123 to be connected and fixed together. The second shell 122 is provided with a start button 1222. The start button 1222 is electrically connected to the main control circuit board 13. The start button 1222 is located on one side of the display 14 and is used to start and stop the nebulization assembly 2. A charging port is provided on the back of the first shell 121. The charging port is electrically connected to the main control circuit board 13. The battery 15 can be charged by inserting a charging cable into the charging port.

[0045] As shown in Figures 1 to 3, 5, and 8 to 11, the present application further provides an easily replaceable atomizing sheet module 22. The atomizing sheet module 22 includes a protective case 221, a silicone sealed case 222, and an atomizing sheet 223. The silicone sealed case 222 is ring-shaped and has two opposing walls, namely, a first wall 222a and a second wall 222b. A mist outlet 2222 is opened in the first wall 222a, and a liquid inlet 22211 is opened in the second wall 222b. The mist outlet 2222 and the liquid inlet 22211 are aligned with each other. The silicone sealed case 222 surrounds and encases the edge region of the atomizing sheet 223, and the protective case 221 encases the silicone sealed case 222. The protective case 221 has two opposing walls, namely, a third wall 221a and a fourth wall 221b. The third wall 221a is adjacent to the first wall 222a. An atomization passage 2212 is provided in the third wall 221a. The fourth wall 221b is adjacent to the second wall 222b. A through opening 2211 is provided in the fourth wall 221b. The atomization passage 2212 is aligned with the atomization outlet 2222, and the through opening 2211 is aligned with the liquid inlet 22211. A connecting nozzle 2221 is provided in the second wall 222b of the silicone sealed case 222. The connecting nozzle 2221 protrudes to the outside of the protective case 221 through the through opening 2211.

[0046] In this embodiment, the silicone sealed case 222 is also a silicone waterproof case. The atomizing sheet 223 is mounted inside the silicone sealed case 222. The silicone sealed case 222 provides waterproof protection for the atomizing sheet 223, and the protective case 221 further protects the silicone sealed case 222. This allows the atomizing sheet 223 to form an independent waterproof and protective structure, making it easy to install and remove as a whole. To install the atomizing sheet 223, simply align and insert the protective case 221 into the mounting recess 2111 provided in the connecting tube 211 of the medicine cup 21. After insertion, the atomizing sheet 223 is electrically connected to the main control circuit board 13 in the control handle 1. At this point, simply covering the atomizing sheet module 22 with the nozzle cover 235 of the nozzle 23 completes the installation, which is simple and quick.

[0047] As can be seen from the above, the atomizing sheet module 22 provided in the embodiment of the present application has a structure in which the atomizing sheet 223 is integrated with a sealed case and a protective case, etc., provided on the outside of the atomizing sheet 223, making it easy to replace the atomizing sheet 223 inside the atomizer 1000.

[0048] In this embodiment, a connection nozzle 2221 is provided on the second wall 222b of the silicone sealed case 222. The connection nozzle 2221 protrudes to the outside of the protective case 221 through a through-hole 2211 of the protective case 221. When the atomizing sheet module 22 is installed in the atomizer 1000, the connection nozzle 2221 connects and communicates with the liquid drop tank 212 in the medicine cup 21. The liquid drop tank 212 communicates with the liquid storage tank 216. When atomizing, the liquid medicine flows from the liquid drop tank 212 into the connection nozzle 2221 and then into the atomizing sheet 223 to be atomized.

[0049] In this embodiment, a through-hole 2211 is provided in fourth wall 221b of protective case 221. Connection nozzle 2221 passes through through-hole 2211. Through-hole 2211 is used to allow connection nozzle 2221 to escape, and also allows the rear end of connection nozzle 2221 to be supported by the protective case, which has a rigid structure, making it easier for connection nozzle 2221 to abut against cup 21 and for liquid inlet 22211 to smoothly communicate with liquid drop chamber 212.

[0050] In this embodiment, the liquid inlet 22211 penetrates the connecting nozzle 2221, and the liquid inlet 22211 is adjacent to the atomizing sheet 223. The liquid inlet 22211 is used to provide a path for the liquid medicine to flow toward the atomizing sheet 223, allowing the liquid medicine to smoothly flow into the atomizing sheet 223 and be atomized.

[0051] In this embodiment, a mist outlet 2222 is provided on the first wall 222a of the silicone sealed case 222. The mist outlet 2222 is adjacent to the atomizing sheet 223. When the atomizing sheet 223 is energized to atomize the medicine, the atomized medicine flows out from the mist outlet 2222 to the outside.

[0052] In this embodiment, the third wall 221a of the protective case 221 is provided with an atomization passage 2212. The atomization passage 2212 communicates with the atomization outlet 2222. The atomization passage 2212 provides a path for the atomized medicinal liquid to flow to the outside. Specifically, in this embodiment, the third wall 221a is provided with a protruding base 221c, and the atomization passage 2212 extends to penetrate the protruding base 221c. The protruding base 221c can be inserted into the nozzle 23 and connected to the nozzle 23. The nozzle 23 is further connected to the mask 3. Because the atomization passage 2212 extends outward to the nozzle 23 and penetrates the nozzle 23, it is possible to prevent water droplets from remaining in gaps around the nozzle 23 or in gaps between the atomization sheet 223 and the silicone sealed case 222 during the atomization process.

[0053] In this embodiment, a flexible circuit board 2231 is provided on one side of the atomizing sheet body 2230 and is electrically connected to the atomizing sheet body 2230. The flexible circuit board 2231 is located inside the silicone sealed case 222. After the atomizing sheet module 22 is inserted into the mounting recess 2111, the flexible circuit board 2231 contacts the first positive and negative conductive top pins 2112 in the mounting recess 2111, thereby forming an electrical connection with the main control circuit board 13 in the control handle 1. When atomizing, the main control circuit board 13 supplies power to the flexible circuit board 2231, which then supplies current to the atomizing sheet body 2230 to operate it. The atomizing sheet body 2230 atomizes the liquid by high-frequency vibration.

[0054] In this embodiment, the flexible circuit board 2231 is provided with positive and negative electrical contacts 22311, one side of the silicone sealed case 222 is provided with a first relief hole 2223, and one side of the protective case 221 is provided with a second relief hole 2213. The positive and negative electrical contacts 22311, the first relief hole 2223, and the second relief hole 2213 are coaxially aligned, allowing the first positive and negative electrode conductive top needles 2112 to pass through them sequentially. After the atomizing sheet module 22 is inserted into the mounting recess 2111, the first positive and negative electrode conductive top needles 2112 pass through the second relief hole 2213 and the first relief hole 2223 in order to contact the positive and negative electrical contacts 22311. The positive and negative electrical contacts 22311 are divided into a positive electrode electrical contact and a negative electrode electrical contact. The first positive and negative electrode conductive top needle 2112 is also divided into a positive electrode conductive top needle and a negative electrode conductive top needle. When in contact, the positive electrode conductive top needle forms a contact-type electrical connection with the positive electrode electrical contact, and the negative electrode conductive top needle forms a contact-type electrical connection with the negative electrode electrical contact, thereby forming an electrical connection circuit between the atomizing sheet 223 and the main control circuit board 13.

[0055] In this embodiment, the silicone sealed case 222 includes a first sealed case 22201 and a second sealed case 22202 (i.e., a first waterproof case and a second waterproof case). The first sealed case 22201 is provided with a storage recess 222011. The atomizing sheet main body 2230 is stored in the storage recess 222011. The second sealed case 22202 is fixedly connected to the first sealed case 22201 and extends into the storage recess 222011. The second sealed case 22202 presses down on the atomizing sheet main body 2230. To facilitate the attachment of the atomizing sheet 223, the silicone sealed case 222 is divided into two parts: the first sealed case 22201 and the second sealed case 22202. To assemble the atomizing sheet 223, first place the atomizing sheet 223 into the receiving recess 222011. Then, place the second sealing case 22202 over the first sealing case 22201, pressing down on the atomizing sheet main body 2230, and engage and secure the first and second sealing cases 22201 and 22202. At this time, the first and second sealing cases 22201 and 22202 seal the flexible circuit board 2231 of the atomizing sheet 223, isolating the flexible circuit board 2231 from the atomization area of ​​the atomizing sheet main body 2230. This prevents water mist from dripping onto the flexible circuit board 2231 below during atomization, effectively preventing short circuits. The connecting nozzle 2221 and liquid inlet 22211 are both located on the first sealing case 22201. The mist outlet 2222 is provided in the second sealed case 22202.

[0056] In this embodiment, the protective case 221 includes a first protective case 22101 and a second protective case 22102. An attachment recess 221011 is provided inside the first protective case 22101, the silicone sealed case 222 is fitted into the attachment recess 221011, and the second protective case 22102 is fixedly connected to the first protective case 22101 to hold the silicone sealed case 222 in place. To facilitate assembly of the silicone sealed case 222 incorporating the atomizing sheet 223, the protective case 221 is divided into two parts, the first protective case 22101 and the second protective case 22102. When packaging the silicone sealed case 222, the silicone sealed case 222 is first fitted into the attachment recess 221011, and then the second protective case 22102 is attached to the first protective case 22101, thereby fixing the silicone sealed case 222 incorporating the atomizing sheet 223 inside the protective case 221. The first protective case 22101 and the second protective case 22102 are fixed together by a mating connection, with an engaging groove 221012 provided at one end of the first protective case 22101 and an engaging hook 221021 provided at one end of the second protective case 22102. The engaging hook 221021 is accommodated inside the engaging groove 221012, allowing the first protective case 22101 and the second protective case 22102 to form a mating connection, thereby facilitating quick assembly. A through opening 2211 is provided in the first protective case 22101, and an atomization passage 2212 is provided in the second protective case 22102.

[0057] In this embodiment, to easily position and attach the atomized sheet module 22 within the mounting recess 2111, multiple positioning bosses 221013 are provided on the outer periphery of the first protective case 22101. The multiple positioning bosses 221013 are evenly spaced circumferentially around the outer periphery of the first protective case 22101. Multiple positioning chutes 2113 are provided within the mounting recess 2111. The multiple positioning bosses 221013 correspond one-to-one to the multiple positioning chutes 2113. When the atomized sheet module 22 is inserted into the mounting recess 2111, the positioning bosses 221013 slide within the positioning chutes 2113, preventing the atomized sheet module 22 from shifting during installation.
