Description

Technical Field

[0001] This invention relates to the field of atomizer technology, and more specifically to a micro-mesh atomizer with a mesh cleaning function. Background Technology

[0002] Micro-mesh nebulizers are devices that use the high-frequency vibration of microporous nebulizer plates to break liquid medicine into micron-sized mist particles. They are widely used in respiratory disease administration, nasal care, and daily humidification. The nebulizer mesh assembly is the core component that determines the nebulization efficiency and quality.

[0003] In existing micro-mesh nebulizers, the atomizing micro-mesh mostly adopts a fixed installation structure, which is fixed relative to the atomizing head body, and the atomizing surface is always set towards the liquid storage chamber. During long-term use, drug crystals, insoluble particles, and environmental impurities in the liquid are prone to deposit on the liquid inlet surface of the atomizing mesh, and gradually embed and block the atomizing micropores, directly leading to a decrease in atomization volume, uneven particle size distribution, and in severe cases, complete failure of the atomization function.

[0004] To address the issue of clogged atomizing mesh, the conventional approach is to directly inject clean water or cleaning fluid into the storage chamber for forward flushing. However, since the clogging impurities are located on the inlet side of the atomizing mesh near the liquid box, and the particle size of the impurities is generally larger than the pore size of the atomizing micropores, forward hydraulic pressure alone is insufficient to push the impurities out of the micropores in the reverse direction, resulting in a very limited cleaning effect and failing to completely remove the blockage. If the atomizing mesh is disassembled for manual cleaning, the frequent disassembly and reassembly are not only cumbersome but also prone to causing deformation of the atomizing mesh, damage to the micropores, and failure of the surrounding sealing structure. Furthermore, it is easy to introduce external contamination, increasing user maintenance costs and the risk of product failure. Summary of the Invention

[0019] The present invention will be further described in conjunction with the following embodiments.

[0020] Depend on Figures 1 to 8 As can be seen, the micro-mesh atomizer with atomizing mesh cleaning function described in this embodiment includes a body 1; a mixing shell 2 is provided on the top of the body 1; a liquid box 3 is fixedly provided on the top of the mixing shell 2; and a rotating shell 4 is rotatably provided between the mixing shell 2 and the liquid box 3. The mixing shell 2 is divided into an atomizing chamber 21 and a cleaning chamber 22 along the circumferential direction; the liquid box 3 is divided into a liquid storage chamber 31 and a drug storage chamber 32 along the circumferential direction; the rotating shell 4 is provided with an atomizing channel 41 extending along the height direction; the liquid storage chamber 31 is connected to the cleaning chamber 22 through the atomizing channel 41; the drug storage chamber 32 is connected to the atomizing chamber 21 through the atomizing channel 41; The atomizing channel 41 is provided with an atomizing mesh assembly 42; a flipping mechanism for flipping the atomizing mesh assembly 42 is provided between the liquid box 3 and the rotating shell 4.

[0021] Specifically, in this embodiment, the micro-mesh atomizer with atomizing mesh cleaning function, during atomization operation, rotates the rotating shell 4 to the atomization position, aligning the atomization channel 41 with the drug storage chamber 32 and the atomization chamber 21. The flipping mechanism maintains the atomizing surface of the atomizing mesh assembly 42 in a horizontal position with its surface facing upwards. The liquid medicine in the drug storage chamber 32 flows into the upper surface of the atomizing mesh assembly 42 in the atomization channel 41. The high-frequency vibration of the atomizing mesh assembly 42 atomizes the liquid medicine into microdroplets, which then descend into the atomization chamber 21 and are finally delivered to the user. Drug delivery is performed at the client end; in cleaning mode, the rotating shell 4 is rotated to the cleaning station, the atomizing channel 41 is aligned with the liquid storage chamber 31 and the cleaning chamber 22, and the flipping mechanism drives the atomizing mesh assembly 42 to complete a 180-degree flip, so that the atomizing surface of the atomizing mesh assembly 42 faces downward, and the cleaning liquid in the liquid storage chamber 31 flows in from the back of the atomizing mesh assembly 42. With the vibration of the atomizing mesh assembly 42, the blockage impurities in the micropores are flushed out from the atomizing surface and discharged into the cleaning chamber 22 along with the cleaning liquid and mist, completing the cleaning without disassembly.

[0022] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The bottom of the liquid box 3 is provided with a liquid storage port 33 communicating with the liquid storage chamber 31 and a drug storage port 34 communicating with the drug storage chamber 32. Specifically, when the rotating shell 4 rotates to the corresponding position, the top opening of the atomizing channel 41 is aligned and connected with the liquid storage port 33 or the drug storage port 34 respectively. The cleaning liquid in the liquid storage chamber 31 flows into the atomizing channel 41 through the liquid storage port 33, and the medicine in the drug storage chamber 32 flows into the atomizing channel 41 through the drug storage port 34. When the position is misaligned, the top surface of the rotating shell 4 blocks the liquid storage port 33 and the drug storage port 34, blocking the liquid from flowing out.

[0023] This embodiment describes a micro-mesh atomizer with a cleaning function. Both the cross-sectional shape of the atomizing channel 41 and the cross-sectional shape of the atomizing mesh assembly 42 are circular. The outer wall of the atomizing mesh assembly 42 abuts against the inner wall of the atomizing channel 41. The circular atomizing mesh assembly 42 can freely rotate and flip within the circular atomizing channel 41. The outer wall of the atomizing mesh assembly 42 abuts against the inner wall of the atomizing channel 41 to form a circumferential seal, forcing all the medicine and cleaning fluid to pass through the atomizing mesh assembly 42, preventing liquid from flowing around the side gaps. Furthermore, during the flipping process, the circular outer wall always remains in contact with the inner wall of the channel, maintaining the sealing effect.

[0024] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The outer wall of the rotating shell 4 is provided with anti-slip teeth 44. When the user rotates the rotating shell 4 to switch positions, their fingers come into contact with the anti-slip teeth 44 on the outer wall, increasing the friction of the contact surface and facilitating the application of torsional force to drive the rotating shell 4 to rotate circumferentially.

[0025] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The outer wall of the atomizing mesh assembly 42 is fixedly provided with a rotating shaft 43; the middle of the rotating shell 4 is provided with a guide post 5; the guide post 5 is provided with a sliding groove 51 extending along the height direction; a sliding block 52 is slidably mounted on the sliding groove 51; and the rotating shaft 43 is rotatably mounted on the sliding block 52. Specifically, during the flipping process of the atomizing mesh assembly 42, the sliding block 52 moves up and down along the sliding groove 51 of the guide post 5, while the rotating shaft 43 rotates around its own axis within the sliding block 52. This provides the atomizing mesh assembly 42 with both axial lifting and circumferential rotational freedom, and, in conjunction with the trajectory drive of the flipping mechanism, completes the combined actions of descending, flipping, and rising.

[0026] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The liquid container 3 has a drive post 6 in the middle; the drive post 6 passes through a guide post 5; and the bottom of the drive post 6 is fixedly connected to the mixing shell 2. The drive post 6 is a fixed reference component. When the rotating shell 4 rotates, it drives the guide post 5 to revolve coaxially around the axis of the drive post 6, causing the sliding block 52, rotating shaft 43, and atomizing mesh assembly 42 inside the guide post 5 to rotate as a whole around the drive post 6, thus enhancing the stability of the overall structure.

[0027] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The flipping mechanism includes a swing block 7 and a drive groove. The rotating shaft 43 is fixedly connected to the swing block 7. The swing block 7 is provided with a first drive pin 71 and a second drive pin 72. The rotating shaft 43 and the first drive pin 71 are coaxially arranged. The drive groove is located on the outer wall of the drive column 6. The first drive pin 71 and the second drive pin 72 are both movably disposed in the drive groove. When the rotating shell 4 rotates, it drives the swing block 7, the first drive pin 71, and the second drive pin 72 to revolve around the drive column 6. Since the drive groove is fixed on the outer wall of the drive column 6, during the revolution, the first drive pin 71 and the second drive pin 72 move along the preset trajectory of the drive groove, causing the swing block 7 to rotate around the axis of the rotating shaft 43. This, in turn, drives the atomizing mesh assembly 42 to flip synchronously through the rotating shaft 43, converting the circumferential rotation of the rotating shell 4 into the flipping action of the atomizing mesh assembly 42.

[0028] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The driving groove includes a first horizontal groove 61 and a second horizontal groove 62 arranged in the circumferential direction. The driving groove also includes a first spiral groove 63 and a second spiral groove 64. The spiral direction of the first spiral groove 63 is opposite to that of the second spiral groove 64. The top of the first horizontal groove 61 is connected to the top of the first spiral groove 63. The bottom of the first spiral groove 63 is connected to the bottom of the second spiral groove 64. The top of the second spiral groove 64 is connected to the second horizontal groove 62.

[0029] Specifically, when the drive pin is in the first horizontal groove 61, the atomizing mesh assembly 42 maintains a horizontal posture with the atomizing surface facing upwards, corresponding to the atomizing position; rotating the rotating shell 4 causes the drive pin to enter the first spiral groove 63, the first drive pin 71 and the second drive pin 72 descend along the spiral trajectory and drive the swing block 7 to rotate in the forward direction, and the atomizing mesh assembly 42 begins to flip; after the first drive pin 71 reaches the bottom of the groove, the second drive pin 72 first enters the second spiral groove 64 in the opposite direction, rises along the spiral trajectory and continues to drive the swing block 7 to rotate in the same direction, the first spiral groove 63 and the second spiral groove 64 cumulatively drive the atomizing mesh assembly 42 to rotate 180 degrees; finally, the first drive pin 71 and the second drive pin 72 enter the second horizontal groove 62, and the atomizing mesh assembly 42 maintains a horizontal posture with the atomizing surface facing downwards, corresponding to the cleaning position.

[0030] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. The drive column 6 is provided with a first metal spring group 81 and a second metal spring group 82. The first metal spring group 81 has a first metal contact group 83 at a first horizontal groove 61; the second metal spring group 82 has a second metal contact group 84 at a second horizontal groove 62; both the first drive pin 71 and the second drive pin 72 are conductive components; the first drive pin 71 and the second drive pin 72 are electrically connected to the atomizing mesh assembly 42. The first metal spring group 81 is electrically connected to the first drive pin 71 and the second drive pin 72; the second metal spring group 82 is electrically connected to the first drive pin 71 and the second drive pin 72. Specifically, when the first drive pin 71 and the second drive pin 72 move to the atomizing position of the first horizontal groove 61, the first drive pin 71 and the second drive pin 72 simultaneously abut against the first metal contact group 83, and the power supply circuit of the atomizing mesh assembly 42 is connected through the first metal spring group 81, and the atomizing mesh assembly 42 starts vibration atomization; when the first drive pin 71 and the second drive pin 72 move to the cleaning position of the second horizontal groove 62, the first drive pin 71 and the second drive pin 72 simultaneously abut against the second metal contact group 84, and the power supply circuit is connected through the second metal spring group 82, and the atomizing mesh assembly 42 starts vibration-assisted cleaning. During the position switching process, the first drive pin 71 and the second drive pin 72 both disengage from the first metal contact group 83 and the second metal contact group 84, and the power supply circuit is disconnected.

[0031] This embodiment describes a micro-mesh atomizer with a cleaning function for the atomizing mesh. Both the first metal contact group 83 and the second metal contact group 84 are provided with contact cone surfaces 85. Both the first drive pin 71 and the second drive pin 72 are provided with receiving grooves 73 for engaging with the first metal contact group 83 and the second metal contact group 84. When the first drive pin 71 and the second drive pin 72 move to the position of the first metal contact group 83 or the second metal contact group 84, the elastic force of the first metal spring group 81 and the second metal spring group 82 presses the first metal contact group 83 and the second metal contact group 84 against the first drive pin 71 and the second drive pin 72. The contact cone surfaces 85 embed into the receiving grooves 73, achieving automatic centering and contact through the guidance of the contact cone surfaces 85, ensuring full contact of the conductive contact surfaces. Simultaneously, the interlocking structure of the contact cone surfaces 85 and the receiving grooves 73 forms a circumferential limit, preventing accidental rotation and displacement of the rotating shell 4.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
