[0011] The atomizer, the mask and the atomizing device provided by the embodiments of the disclosure have at least the following beneficial effects.

[0012] According to the wearable atomizer provided by the disclosure, the mask comprises a first end and a second end facing each other, the first end is used to contact the user's face, and the second end is used to connect a plurality of components necessary in the atomizer. The second end of the mask extends in the width direction, and the middle part of the second end protrudes outward more than the two sides (further away from the first end). The plurality of components are electrically connected to realize the atomizing function, and the plurality of components include a component containing a mist outlet, and the mist outlet is in communication with the chamber of the mask. Among them, the plurality of components are arranged on at least part of the outer surface of the second end in the width direction. Relative to the user's face, the second end forms a curved surface with the middle part protruding outward and the two sides retracting inward in the width direction, which is more fitted to the user's face as a whole. The plurality of components are arranged on at least part of the outer surface of the second end in the width direction, and the center of gravity is relatively closer to the first end. In this way, the center of gravity of the atomizer as a whole is closer to the user's face, and the force required to hold the atomizer on the user's face is small, so that it is possible to hold the atomizer on the user's face by the tensile force of the strap that the human body can tolerate, and the user's fatigue during the atomizing inhalation process is eliminated.

[0013] According to the integrated atomizer provided by the disclosure, the main machine is directly fixed to the second end of the mask, and the atomizing component is directly fixed to the main machine, so that the main machine with a larger volume and mass is closer to the mask, and the integration degree is high; and the volume of the main machine is large, which can have a larger surface, increasing the freedom degree of the connection form of the main machine with the mask and / or the atomizing component. The components in the main machine can also be more freely arranged. The material of the mask is generally soft rubber, and it is not convenient and stable to install other parts directly on the mask, while the main machine is a structure with certain strength. After fixing other parts to the main machine, the main machine is fixed to the mask, and the assembly is simpler and more stable.

[0014] According to the detachable atomizer provided by the disclosure, the mask and the main machine are detachably connected through a plurality of concave-convex fitting structures, and the connection structure between the mask and the main machine can be more free (no longer limited by the connection mode of the mist outlet pipe of the medicine cup), which is suitable for forming a more convenient detachable connection.

[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.

[0036] The features and exemplary embodiments of various aspects of the present disclosure will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that the present disclosure can be practiced without some of these specific details. In the following description of the embodiments, reference is made to the drawings where like reference numerals indicate like structures. The following detailed description is merely illustrative and is not intended to limit the present disclosure to the particular embodiments described. Variation and modifications exist within the scope and spirit of the present disclosure. The present disclosure covers structural, material, and constructional modifications or changes in the parts, components and configurations of the embodiments as well as any other modifications or changes that come within the spirit and scope of the present disclosure. In the drawings and the following description, well-known structures and techniques have not been shown in order to avoid unnecessary obscurity of the present disclosure.

[0037] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure.

[0038] The existing atomization inhaler (referred to as atomizer) is divided into a split type atomizer and a whole type atomizer. The face mask and the main machine of the split type atomizer are separated, and the main machine provides the atomized medicine to the face mask through a pipeline. The whole type atomizer is mostly handheld, mainly including a handheld atomization main machine, a medicine cup and a face mask which are rigidly connected. In order to facilitate the user to hold, the main machine of the whole type atomizer is generally designed as a column shape, and the face mask is generally extended radially outward from the peripheral surface of the column. When the user uses, the user needs to hold the atomization main machine and cover the face mask on the mouth and nose, and needs to keep holding during the use. Some face masks are provided with a strap which can be wrapped around the user's head or ears, so as to reduce the user's fatigue of holding the main machine for a long time. However, due to the fact that the main machine is relatively in front of and below the user's face, it is difficult to completely keep the atomizer on the user's face by only using the strap. This condition causes the user to still need to hold the main machine during use, and still cannot make the user free from holding the atomizer.

[0039] The wearable atomizer provided by the present disclosure includes a face mask and a plurality of components. The face mask is used to cover the user's face, and the plurality of components are necessary components for realizing the atomization function. The face mask includes first and second ends which are opposite to each other, the first end is used to contact the user's face, the second end and the entity between the second end and the first end define a chamber for accommodating the atomized medicine, the second end extends in the width direction, the middle part of the second end protrudes outward relative to the two sides, and the outer surface of the second end is used to directly or indirectly connect the plurality of components. The plurality of components are electrically connected to realize the atomization function, and the plurality of components include a component containing an atomization outlet, the atomization outlet is communicated with the chamber of the face mask; wherein the plurality of components are arranged on at least part of the area of the outer surface of the second end of the face mask in the width direction. In this form of atomizer, the middle part of the second end of the face mask is the outermost, the two sides of the middle part are bent towards the first end and close to the user's face, and the plurality of components are distributed in the width direction of the entire second end or at least part of the area of the second end. The more the components distributed on the outer side of the width direction of the second end, the closer the center of gravity of the components to the user's face, so that the above setting makes at least part of the components closer to the first end of the face mask, so that the center of gravity of the whole atomizer is closer to the user's face. When the distance between the center of gravity of the atomizer and the user's face is small, the force arm between the center of gravity and the fulcrum (the contact part between the first end and the user's face) is small, and the torque caused by the gravity is small, so that the atomizer is suitable for being kept on the user's face by the tension provided by the strap which can be borne by the user to overcome the torque caused by the gravity. In the present application, the "width direction" refers to the left-right direction (the direction perpendicular to the sagittal plane) of the user when the user's upper body is upright from the perspective of the user wearing the atomizer. Similarly, the height direction is the up-down direction of the user, and the thickness direction is the front-back direction of the user.

[0040] In addition, the inventors also noticed the following problems: the layout of each main component in the atomizer is scattered, the overall integration is low, the volume is large, and it is difficult to make the whole atomizer wearable on the user's face.

[0041] Therefore, the present disclosure also provides an integrated nebulizer. The integrated nebulizer comprises a mask, a main machine and a nebulizing assembly. The mask comprises a first end and a second end facing opposite directions, the first end being used to contact a user's face, the second end and an entity between the second end and the first end defining a chamber for accommodating a medicament mist; the main machine comprises a device for providing power and / or control signals; the nebulizing assembly comprises a medicine cup and a nebulizing sheet assembly arranged at the bottom of the medicine cup; wherein the main machine is fixed to the second end of the mask, and the nebulizing assembly is fixed to the main machine. The main machine and the mask can be detachably fixedly connected or non-detachably fixedly connected. The present disclosure provides an integrated nebulizer, in which the main machine is directly fixed to the mask, and the nebulizing assembly is directly fixed to the main machine, so that the main machine with a larger volume and mass is closer to the mask, and the integration degree is high; and the main machine has a larger volume and is suitable to be formed into a shape with a larger surface, so as to increase the freedom degree of the connection form of the main machine, the mask and / or the nebulizing assembly.

[0042] Reference is made to FIGS. 1-8. FIG. 1 is a schematic view of a nebulizer according to an embodiment of the present disclosure. FIG. 2 is an exploded view of the nebulizer shown in FIG. 1. FIG. 3 is a view of the nebulizer shown in FIG. 1 from the direction facing the first end of the mask 200. FIG. 4 is a view of the nebulizer shown in FIG. 1 from the side of the outlet of the first assembly. FIG. 5 is an axonometric view of the mask 200 of the nebulizer shown in FIG. 1. FIG. 6 is a top view of the mask 200 shown in FIG. 5. FIG. 7 is an exploded view of the main machine 100 of the nebulizer shown in FIG. 1. FIG. 8 is a schematic view of the main machine 100 shown in FIG. 7 with the front shell 110b removed.

[0043] The nebulizer shown in FIGS. 1-8 can be a wearable nebulizer or an integrated nebulizer according to the present disclosure. More specifically, the integrated nebulizer can be a wearable nebulizer.

[0044] Specifically, the atomizer (such as a wearable atomizer, an integrated atomizer) comprises a main machine 100, a mask 200, a first assembly 300, and a strap 400. The main machine 100, the mask 200, and the first assembly 300 are integrated into one whole, and two ends of the strap 400 are connected to the whole and can hold the whole on the face of a user. Among them, the first assembly 300 is used to store and atomize liquid medicine. In some embodiments, the first assembly 300 comprises an atomization assembly 300 (which can also be referred to as an atomization device 300). The atomization assembly 300 or the atomization device 300 comprises an atomization piece assembly and a medicine cup. The medicine cup is used to contain liquid medicine, and the atomization piece assembly is used to receive and atomize the liquid medicine of the medicine cup and deliver the atomized liquid medicine into the mask 200. For example, the atomization piece assembly diffuses the atomized liquid medicine into the inner cavity 230 of the mask 200. The atomization piece assembly in the present embodiment is a micro-mesh atomization piece, which atomizes the liquid medicine by making the mesh vibrate at a high frequency through a piezoelectric ceramic. The main machine 100 comprises a rack 110 and necessary electrical assemblies 120 (such as a second assembly 120) contained therein. The electrical assemblies 120 or the second assembly 120 comprise a battery 121 and a control device 122. The rack 110 in the present embodiment is a shell that can contain devices inside. For example, the rack 110 is in the form of a shell enclosed by a sheet structure. The inside of the shell is a chamber where components can be installed. The shell has a large width and a small thickness. The two outer surfaces in the thickness direction of the shell are a first end surface 113a facing the mask 200 and a second end surface 113b facing away from the mask 200. The first assembly 300 is electrically connected to the second assembly 120, and the second assembly 120 provides necessary power and control signals to the first assembly, and the two assemblies together realize the atomization function. For example, the atomization assembly 300 is electrically connected to the electrical assembly 120, and the two assemblies together realize the atomization function.

[0045] For ease of description, the first assembly 300 is taken as the atomization assembly 300, and the second assembly 120 is taken as the electrical assembly 120 in the following description. It should be noted that the first assembly 300 and the second assembly 120 can also be any other assemblies that can realize corresponding functions.

[0046] The orientation of the atomizer shown in FIG. 1 is consistent with the orientation of the atomizer when worn on the face of a user. When viewed from above, the frame 110 is generally V-shaped, including a first side wing 111 and a second side wing 112 connected at an obtuse angle (e.g., 115 degrees) to each other. The first side wing 111 and the second side wing 112 are each flat and rectangular box-shaped. The open side of the V-shaped frame 110 is configured to connect with the face shield 200. Specifically, the frame 110 includes a V-shaped front shell 110b and a V-shaped rear shell 110a, each of which is surrounded by a flange protruding normal to the main plane of the shell. The front shell 110b and the rear shell 110a are connected to each other by the flanges to form the V-shaped frame 110 as a whole. The rear shell 110a is closer to the face of the user relative to the front shell 110b (from the perspective of the user, the front shell 110b is in front of the rear shell 110a). The inner surface of the rear shell 110a connects with the front shell 110b, and the outer surface forms a first end surface 113a of the frame 110 for connecting with the face shield 200.

[0047] A flat accommodation space 114 is formed inside the frame 110. As used herein, flat means that the thickness of the accommodation space 114 is small, i.e., the thickness is less than the height and the width. In other words, from the perspective of the user, the accommodation space 114 has a smaller dimension in the front-to-back direction than in the up-to-down direction and the left-to-right direction. This arrangement allows the frame 110 to have a center of gravity close to the face of the user when mounted on the face shield 200.

[0048] Specifically, the space on the side of the first side wing 111 of the accommodation space 114 is semi-open, and is provided with a recess 116. More specifically, the portion of the rear shell 110a corresponding to the first side wing 111 is provided with a rounded rectangular fence 115 inside; the portion of the front shell 110b corresponding to the first side wing 111 is provided with a window W; the window W and the fence 115 together form the recess 116 on the first side wing 111. The bottom of the recess 116 is provided with a second through hole 117 and a magnet 118. The side wall of the recess 116 is provided with a contact 119. The space on the side of the second side wing 112 of the accommodation space 114 is closed.

[0049] The electrical components 120 are mounted inside the second side wing 112 of the frame 110. The electrical components 120 include a battery 121 and a control device 122, which are arranged in the width direction of the second side wing 112.

[0050] The atomization assembly 300 is detachably mounted to the main machine 100. Specifically, the atomization assembly 300 is mounted in the recess 116 of the first side wing 111 of the machine frame 110. The atomization assembly 300 is flat in shape and parallel to the first side wing 111 when mounted in the recess 116, most of the structure of the atomization assembly 300 is located in the accommodation space 114 of the machine frame 110, and a small part of the structure protrudes from the outer surface of the front shell 110b. The mist outlet 333 of the atomization assembly 300 is in communication with the second through hole 117 at the bottom of the recess 116. The atomization assembly 300 is also provided with a contact point which is electrically connected with the contact point 119 in the recess 116. When the atomization assembly 300 is mounted to the machine frame 110, the contact point of the atomization assembly 300 will be electrically connected with the contact point 119 provided in the recess 116, thereby conducting control signals and / or power. The atomization assembly 300 is also provided with a ferromagnetic structure for forming a magnetic connection with the magnet 118 at the bottom of the recess 116, so that the atomization assembly 300 is retained in the recess 116 and is convenient to be taken out from the recess 116.

[0051] The face mask 200 is used to cover the mouth and nose of the user, and the chamber 230 inside the face mask 200 can hold the atomized liquid medicine around the mouth and nose of the user. As shown in FIGS. 3, 5 and 6, the face mask 200 includes a first end 210 and a second end 220 facing opposite directions, and the second end 220 and the first end 210 and the second end 220 define a chamber 230 for accommodating the medicine mist. The first end 210 of the face mask 200 is used to contact the face of the user, and the second end 220 is used to connect the main machine 100. The end surface of the second end 220 is an outer surface S. The outer surface S extends along the width direction from the middle to both sides. The outer surface S has a large width (the width is greater than the height), so it has a large area in the width direction for the main machine to attach. The second end 220 is provided with a hard end plate, which is convenient for connecting with the machine frame 110.

[0052] In this embodiment, the outer surface S includes a first side portion 221, a second side portion 222, and a middle portion 223. The first side portion 221 and the second side portion 222 are distributed on both sides of the middle portion 223, forming an outward convex surface relative to the user's face. In this embodiment, the first side portion 221 and the second side portion 222 form a V-shaped curved surface, and the middle portion 223 can be regarded as the junction of the first side portion 221 and the second side portion 222. The middle portion 223 is more convex forward relative to the first side portion 221 and the second side portion 222. When taking the inside and outside of the mask 200 as a reference (the direction of the mask 200 facing the user's face is inside, and the direction away from the user's face is outside), the middle portion 223 is convex outward relative to the first side portion 221 and the second side portion 222. In other words, the first side portion 221 and the second side portion 222 are closer to the user's face. In this way, the part corresponding to the middle portion 223 in the inside of the mask 200 can accommodate the user's nose. The first side portion 221 and the second side portion 222 extend to both sides in the width direction and gradually tilt backward in the front-back direction, which can not only adapt to the shape of the user's face, but also form a larger surface to facilitate the direct or indirect attachment of other structures / parts. The first side portion 221 is also provided with a first through hole 224, which is used in cooperation with the mist outlet 333 of the atomization assembly 300, so that the mist generated by the atomization assembly 300 can reach the chamber 230 of the mask 200. In the illustrated embodiment, the mist outlet 333 is the port of the mist outlet pipe, and the mist outlet 333 extends into the chamber 230 through the first through hole 224; in some alternative embodiments, the mist outlet pipe can also have a smaller length, so that the mist outlet 333 does not enter the chamber 230 in the axial direction of the first through hole 224, and the drug mist sprayed from the mist outlet 333 can enter the chamber 230 through the first through hole 224.

[0053] It should be understood that the "V-shaped" second end 220 of the mask 200 here is not limited to a structure with a corner formed by connecting two planar structures at a certain angle, but also includes other similar shapes, as long as the end surface of the second end is convex forward and the parts on both sides of the middle portion extend obliquely to the rear side when the mask covers the user's face. Such shapes should fall within the scope claimed by the present disclosure. For example, relative to the structure shown in FIG. 5, the middle portion can be a planar shape with a larger width, a curved surface shape, or other shapes; in addition, the first side portion 221 and / or the second side portion 222 can also have a certain curvature.

[0054] The second end 220 of the face cover 200 has a shape that is adapted to the first end surface 113a of the main body 110. When the face cover 200 is connected to the main body 100, the main body 110 is directly fixed to the outer surface S of the face cover 200. The atomization assembly 300 and the electrical assembly 120 inside the main body 110 are arranged close to the first side 221 and the second side 222 of the second end 220 of the face cover 200 (only separated by the wall of the rear shell 110a). In this way, the electrical assembly 120 and the atomization assembly 300 can be close to the outer surface S of the face cover 200, and most of the structure of the main body 110 is also close to the outer surface S of the face cover 200, so that the center of gravity of the main body 100 and the atomization assembly 300 can be closer to the first end 210 of the face cover 200. The closer the center of gravity of the main body 100 and the atomization assembly 300 is to the first end 210 of the face cover 200, the smaller the torque generated by the gravity on the main body 100 and the atomization assembly 300, and the smaller the force required to hold the atomizer on the user's face.

[0055] In some optional embodiments, the main body 110 can not be provided in the atomizer. The atomization assembly 300 and the electrical assembly 120 can be directly connected to the second end 220 of the face cover 200. In other optional embodiments, the atomization assembly 300 and the electrical assembly 120 can be directly connected to the second end 220 of the face cover 200, and the main body 110 only includes the front shell 110b connected to the second end 220 to cover the atomization assembly 300 and the electrical assembly 120.

[0056] In some optional embodiments, the surface of the atomization assembly 300 is flush with the outer surface of the main body 110. In other optional embodiments, the atomization assembly 300 can be completely installed inside the main body 110 in a detachable or non-detachable manner (the front shell 110b of the main body 110 does not need to be provided with a window W), and only the liquid inlet port can be in communication with the outside.

[0057] In some optional embodiments, the surface of the second end 220 of the face cover 200 can also be other outwardly convex curved surfaces, such as a curved surface that is a whole circular arc, that is, the first side 221 and the second side 222 themselves have a certain curvature and the transition between them is smoother, rather than forming a corner-shaped middle part 223.

[0058] In some optional embodiments, the angle between the first side 221 and the second side 222 of the second end 220 of the face cover 200 can also be greater than or less than 115 degrees, such as 90 degrees, 110 degrees, 120 degrees, 130 degrees, or 150 degrees, as long as it is between 90 degrees and 150 degrees.

[0059] In some alternative embodiments, the arrangement of the atomization assembly 300 and the electrical assembly 120 on the outer surface S is not limited to the forms in the foregoing embodiments, and can also be: some electronic devices in the electrical assembly 120 are arranged in the first side portion 221 or the middle portion 223; or the atomization assembly 300 is arranged in the middle portion 223, and the electronic devices in the second assembly 120 are distributed in the first side portion 221 and / or the second side portion 222; or the atomization assembly 300 and the electrical assembly 120 are both arranged in the first side portion 221 or the second side portion 222 (in this case, the first side portion 221 or the second side portion 222 needs to have a larger area to accommodate the atomization assembly 300 and the electrical assembly 120).

[0060] In some alternative embodiments, the second end 220 of the mask 200 is a hard end plate, which is easier to arrange a connection structure that needs to bear a certain force, relative to the soft first end 210. As described above, the second end 220 can also be provided with a hard end plate to facilitate connection with the mainframe 110. Specifically, as shown in FIG. 9, the second end 220 of the mask 200 has a double-layer structure, and the inner side of the second end 220 in the mask 200 is a hard inner plate 240, and the outer side is a soft rubber of the same material as the first end 210. In this way, the second end 220 as a whole has a certain rigidity and is suitable as an attachment base for other structures. The soft layer can be integrally formed with other parts of the mask.

[0061] The present disclosure also provides a mask for a wearable nebulizer, such as the mask 200 in the wearable nebulizer in the foregoing embodiments. The mask 200 includes a first end 210 facing opposite a second end 220, the first end 210 being configured to contact a user's face, and the second end 210 and the entity between the second end 220 and the first end 210 defining a chamber 230 for accommodating a medicament mist, the second end 220 extending in a width direction from a middle portion to both sides, and the middle portion of the second end 220 in the width direction being convex outward relative to the two sides; at least a part of an outer surface S of the second end 220 in the width direction is configured to secure a plurality of assemblies, the plurality of assemblies being electrically connected to each other to achieve a nebulization function, and the plurality of assemblies including an assembly including a mist outlet 333, the mist outlet 333 being in communication with the chamber 230 of the mask. The specific structure of the mask 200 can be referred to the mask 200 described in the foregoing embodiments. The mask 200 can be detachably connected to the mainframe 100 as a replacement part. The outer end surface / outer surface of the second end 220 of the mask 200 has a larger size in the width direction, so that the plurality of assemblies can be distributed in the width direction rather than stacked in the thickness direction, avoiding the center of gravity of the plurality of assemblies being too far outward.

[0062] In addition, the inventors have also noticed the following problem: the atomization assembly in the atomizer needs to be in communication with the medicine cup to receive the liquid medicine, and also needs to deliver the medicine mist to the inside of the mask, so the atomization assembly usually has to be provided with at least two interfaces, one of which is in communication with the medicine cup, and the other of which is in communication with the mask. If the integration of the atomizer is to be further improved, it is usually considered to reuse the existing interface. For example, the interface used by the atomization assembly to output the medicine mist is not only a fluid passage, but also a physical interface to serve as a mechanical connection. For example, the interface is usually provided in a tubular structure, the inside of the tube is used to output the medicine mist, and the outer circumferential surface of the tube is used to connect the mask, so that the delivery of the medicine mist and the physical connection and integration of the atomization assembly and the mask are achieved. The disadvantage of this connection mode is that the tubular structure usually has a small diameter and / or length, and the connection position / area with the mask is limited, and usually the connection is provided as a fixed connection that cannot be disassembled for stability. Since the mask cannot be disassembled, attention should be paid to prevent the cleaning liquid from spreading to the area outside the mask when cleaning the mask, because other areas are provided with circuit boards, electrical connection contacts, batteries or power supply interfaces and other devices that need to be protected from water.

[0063] Therefore, the present disclosure also provides a mask-disassemblable integrated atomizer, in which the main machine and the mask are in disassemblable connection. The main machine is provided with devices for providing power and / or control signals. The mask includes a first end and a second end facing opposite directions, the first end being used to contact the user's face, and the second end being used to connect the main machine. The mask is disassemblably arranged on the main machine through the second end. The mask and the main machine are connected to each other through physical structures, and the atomization assembly is fixed to the main machine, and the mist outlet of the atomization assembly only needs to be in communication with the mask without physical connection. Without the limitation of physical connection between the mask and the atomization assembly through the mist outlet, the connection mode between the mask and the main machine can be more free, so that a larger connection area or more connection structures can be provided to facilitate the realization of a disassemblable connection structure. Therefore, the mask can be stably connected to other structures, and can also be easily disassembled for thorough cleaning or replacement. The atomization assembly can also be provided in a disassemblable form, and the connection mode between the atomization assembly and the main machine is also more free.

[0064] Referring further to Figures 10 and 11. Figure 10 is a structural schematic diagram of the front shell in Figure 7 from another direction. Figure 11 is a cross-sectional view of the atomizer with the atomizing component 300 omitted. The atomizer can be an integrated atomizer. The main unit 100 and the face mask 200 are in their initial separated position, and the cross-section passes through the center lines of the first positioning post 10 and the second positioning post 20. The face mask 200 and the main unit 100 are detachably connected by multiple interlocking structures, including at least a first interlocking structure and a second interlocking structure. The interlocking directions of the first and second interlocking structures are not parallel. When the mating directions of the first and second concave-convex mating structures are not parallel, the fit between the concave and convex structures does not need to be a tight fit to achieve a stable connection between the mask and the main unit. This is because when the mask and the main unit separate, during the process of the convex structure being pulled out of the concave structure, the scanning envelope of the outer contour of the convex structure will interfere with the inner surface of the concave structure. This is equivalent to the inner surface of the concave structure forming a limit on the convex structure. In this way, the mask 200 and the main unit 100 are connected.

[0065] The stable connection does not require very precise dimensional fit and / or geometric tolerances between the interlocking structures, which helps to improve the fault tolerance rate and reduce the processing cost.

[0066] Specifically, the second end 220 of the face mask 200 is provided with a first structure and a second structure for connecting to the frame 110. The first structure is a first mounting hole 225, and the second structure is a second mounting hole 226. The outer surface of the second end 220 is generally a V-shaped curved surface, extending in width, specifically including a first side portion 221 and a second side portion 222 distributed on both sides in the width direction. The first mounting hole 225 is located on the first side portion 222, and the second mounting hole 226 is located on the second side portion 222. The first side portion 221 and the second side portion 222 are each approximately planar, so their normal directions are not parallel. The axes of the first mounting hole 225 and the second mounting hole 226 are both along the normal direction.

[0067] In the frame 110, a third structure and a fourth structure are provided on the surface of the first end face 113a. The third structure is a first positioning post 10, and the fourth structure is a second positioning post 20. The first positioning post 10 and the second positioning post 20 are respectively distributed on the corresponding portions of the first side wing 111 and the second side wing 112 of the first end face 113a. The first side wing 111 and the second side wing 112 are neither coplanar nor parallel, but have a certain included angle. Therefore, the first positioning post 10 and the second positioning post 20 also have a non-parallel positional relationship. A first mounting hole 225 is provided on the first side portion 221 of the second end 220, and a second mounting hole 226 is provided on the second side portion 222 of the second end 220.

[0068] When the frame 110 is connected to the second end 220, the first positioning column 10 is inserted into the first mounting hole 225 of the mask 200 to form a first concave-convex fitting structure, and the second positioning column 20 is inserted into the second mounting hole 226 of the mask 200 to form a second concave-convex fitting structure. In addition, the first mounting hole 225 and the second mounting hole 226 are through holes, and the top ends of the first positioning column 10 and the second positioning column 20 extend into the mask 200. Therefore, when the main machine 100 and the mask 200 need to be separated, the user can push the top ends of the first positioning column 10 and the second positioning column 20 from inside the mask 200 to separate the fitting structure. The second end 220 is a hard end plate, which is easier to set the connection structure that needs to bear a certain force than the soft first end 210. Specifically, the mask 200 has a double-layer structure, and the second end 220 is located on one side of the mask 200, which is a hard inner plate 240, and the other side is a soft rubber with the same material as the first end 210. In this way, the second end 220 has a certain rigidity as a whole, which is suitable for being attached to other structures. The soft layer can be integrally formed with other parts of the mask.

[0069] In addition, when the main machine 100 and the mask 200 are separated, they move away from each other in the front-rear direction with the user as the reference, and the direction away from each other is not parallel to the axial direction of the first positioning column 10 / second positioning column 20. Therefore, an interference is formed between the circumferential surface of the positioning column and the side wall of the mounting hole in the fitting structure, which prevents the unexpected separation of the two. Because a large enough force or a suitable separation operation is required to separate the two. In this embodiment, the second end 220 of the mask 200 has a large width as a whole, and even if the second end 220 is a hard plate structure, it also has a certain elasticity. Therefore, when the user forcibly separates the two, the second end 220 will be deformed to a certain extent to allow the first positioning column 10 and the second positioning column 20 to be pulled out of the mounting hole. In addition, the first positioning column 10 and the second positioning column 20 are distributed on the two side wings of the frame 110 in the width direction, and the distance between them is large. First, when only the first positioning column 10 is pressed, the main machine 100 will rotate relative to the mask 200 with the second positioning column 20 as the reference, and the first positioning column 10 is more easily pulled out of the first mounting hole 225. After the first positioning column 10 is separated from the first mounting hole 225, the second positioning column 20 is pressed to be pulled out of the second mounting hole 226. Through the above suitable separation operation, the force required for the operation in the separation process is small.

[0070] In addition, the straps 400 are installed at both ends of the main body 100 on the rack 110, and the face mask 200 is not directly connected to the straps 400, so that the face mask 200 does not need to be replaced when the straps 400 are replaced. Thus, when the face mask 200 needs to be discarded and replaced with a new face mask, less structure needs to be discarded. In addition, the straps 400 can directly bind the main body 100, and when the straps 400 are installed on the face mask 200, the face mask 200 can have a tendency to sag due to the softness of the face mask 200 and the large mass of the main body 100.

[0071] In addition, the atomization assembly 300 as a whole can be conveniently removed from the main body 100, making the operation of adding liquid medicine and cleaning the medicine cup more convenient. If the atomization assembly 300 is damaged, only a new atomization assembly 300 needs to be replaced, without scrapping the entire atomizer.

[0072] In some optional embodiments, a convex structure such as a positioning column can also be provided on the second end of the face mask 200, and a concave structure such as a mounting hole can also be provided on the main body 100. In other optional embodiments, more concave-convex fitting structures such as three or four can also be provided. Among the plurality of concave-convex fitting structures, the fitting directions of at least two concave-convex fitting structures are not parallel.

[0073] In some optional embodiments, the outer surface of the second end 220 can also be arc-shaped (viewed downward), and the surface of the main body 100 that is engaged with the second end 220 also has a shape that is adapted thereto. The outer surface of the second end 220 is provided with a plurality of mounting holes. In the width direction, any two parts of the second end 220 are not parallel, so that the recess directions of the two mounting holes provided at any two parts in the width direction are not parallel. Correspondingly, the surface of the main body 100 that is engaged with the second end 220 is provided with a plurality of positioning columns, and the plurality of positioning columns are (radially) protruding and have a non-parallel relationship between the positioning columns.

[0074] Further, the inventors have also noticed the following problem: reducing the overall size and / or weight of the atomizer, or making the center of gravity as close to the user's face as possible, is conducive to keeping the atomizer on the user's face only by the straps. However, the drug mist released by the atomizer needs to move a sufficient distance to be diffused to a state suitable for the user to inhale. If the size of the atomizer is too small, the drug mist can reach the user's mouth and nose in a state of insufficient diffusion, which is not conducive to the user's inhalation and will make the user feel uncomfortable when being hit by the drug mist.

[0075] Therefore, the present disclosure also provides an atomization device for converting a liquid medicine into a medicine mist. The atomization device is part of an atomizer. The atomization device can belong to a first assembly, for example, the atomization device is the atomization assembly described above. Hereinafter, it will be introduced as an atomization device. The atomization device includes a medicine cup, an atomization sheet assembly, and a mist outlet tube. The medicine cup has a chamber for containing a liquid medicine, and the bottom of the chamber is provided with a medicine outlet. The medicine cup has a first surface, and the first surface faces the main machine when the atomization device is installed in the atomizer. The atomization sheet assembly has an inner side and an outer side, the inner side and the outer side are opposite in direction, the inner side is used to receive the liquid medicine, and the outer side is used to release the medicine mist. The inner side is sealingly connected between the medicine outlet of the chamber. The mist outlet tube has a first end and a second end, the first end is sealingly connected with the outer side of the atomization sheet assembly, and the second end forms a mist outlet. The mist outlet tube is used for the medicine mist released by the atomization sheet assembly to pass through and enter the external environment. Among them, the first surface of the medicine cup is provided with a recess, the atomization sheet assembly is located in the recess, and at least a part of the mist outlet tube is arranged in the recess. When the overall length of the mist outlet tube is unchanged, one of the pipe bodies is arranged in the recess, so that the overall size of the atomization device in the axial direction of the mist outlet tube is reduced, which is equivalent to the overall thickness of the atomization device is reduced. The atomizer with the above atomization device is more conducive to realizing light weight / miniaturization.

[0076] Further reference is made to FIGS. 13-15, FIG. 13 is an isometric view of the atomization device in the atomizer shown in FIG. 1, FIG. 14 is a front view of the atomization device shown in FIG. 13, and FIG. 15 is an A-A sectional view of FIG. 14.

[0077] The atomization device 300 includes a medicine cup 310, an atomization sheet assembly 320, a mist outlet tube 330, a first magnetic attraction structure 341, a second magnetic attraction structure 342, a probe 350, and a contact 360. The medicine cup 310 is a flat container for containing a liquid medicine, and the bottom thereof is provided with a medicine outlet 315. The atomization sheet assembly 320 is used to receive the liquid medicine flowing out of the medicine outlet 315. The mist outlet tube 330 is coaxially arranged with the atomization sheet assembly 320, and is used to define a discharge path of the medicine mist output by the atomization sheet assembly 320. The first magnetic attraction structure 341 and the second magnetic attraction structure 342 are used to cooperate with the magnets on the main machine 110 to retain the atomization device 300 on the main machine 110. The probe 330 is located below the medicine outlet 315 and is used to detect the liquid level of the liquid medicine. The contact 360 is used for power transmission and control signal transmission between the atomization device 300 and the main machine 100.

[0078] Referring to FIGS. 16-18, the structure of the medicine cup 310 is shown. The medicine cup 310 includes a main housing 311, an outer housing 312, a see-through panel 313, a medicine adding port 318, a plug 317, and a recess 319. The main housing 311 and the see-through panel 313 together enclose a chamber C, and the outer housing 312 is used to keep the see-through panel 313 as a whole with the main housing 311. The medicine cup 310 is generally a flat rectangular box, with a width slightly greater than a height, and a minimum thickness. Two sides of the medicine cup 310 in the thickness direction are a first surface S1 and a second surface S2, respectively. When the medicine cup 310 is installed in the main machine 100, the first surface S1 faces the main machine 100. The recess 319 is provided on the first surface S1.

[0079] The main housing 311 includes a rectangular main side plate and a standing plate surrounding the edge of the main side plate, which enclose an open space. The outer surface of the main side plate corresponds to the first surface S1. In the orientation shown in FIG. 18, the opening of the open space faces the side, and the top of the open space has the medicine adding port 318. The lower half of the open space is provided with a bottom plate 314, and the space between the bottom plate 314 and the standing plate above it is the chamber C for containing the medicine liquid. The space below the bottom plate 314 can be used to install electrical components. The bottom plate 314 includes a horizontal extension and a vertical extension. One end of the horizontal extension is connected to a standing plate on one side of the medicine cup 310 in the width direction (the left side in the figure), and the other end extends to the standing plate opposite to the aforementioned one (the right side in the figure) at a small angle. The lower end of the vertical extension of the bottom plate 314 starts from the other end of the horizontal extension, and the whole extends upward at an angle. The upper end is connected to the standing plate (the right side in the figure). This arrangement allows the medicine liquid to flow to the junction of the horizontal extension and the vertical extension, and the medicine outlet 315 is provided at the junction. Referring to FIG. 17. The recess 319 is recessed from the first surface S1, and its shape is generally a cylindrical hole. The recess 319 intersects the first surface S1 at an angle, i.e., the recess 319 does not extend along the normal direction of the first surface S1, but extends at a small angle (e.g., 14 degrees) with the normal direction of the first surface S1. The bottom of the recess 319 is also provided with a through hole. In the extension direction of the recess 319, the projection of the recess 319 does not completely fall into the chamber C, and only the projection of the upper half of the area falls into the chamber C. The aforementioned through hole is provided in the overlapping area of the bottom of the recess 319 and the chamber C in the projection direction, and the through hole forms the medicine outlet 315 at the bottom of the chamber C.

[0080] The perspective panel 313 is a substantially rectangular plate structure with rounded corners, which can cover the opening of the main housing 311. The outer housing 312 is buckled on the main housing 311, and the inner surface of the outer housing 312 surrounds the outer circumferential surface of the vertical plate of the main housing 311, and the perspective panel 313 is pressed against the end surface of the vertical plate of the main housing 311. The perspective panel 313 and the main housing 311 jointly form the chamber C, that is, both are walls of the chamber C. In the present embodiment, the outer housing 312 is also provided with a window, and the main body of the perspective panel 313 corresponds to the window. When the perspective panel 313 is made of transparent material, the user can observe the amount of liquid medicine from the window. The perspective panel 313 is located on the second surface S2 side of the medicine cup 310.

[0081] The main housing 311, the outer housing 312 and the perspective panel 313 are assembled together to form the main body structure of the medicine cup 310. The inside of the medicine cup 310 forms a chamber C for containing liquid medicine, and the top is provided with a medicine adding port 318 for pouring liquid medicine into the chamber C. The medicine adding port 318 is provided with a pluggable plug 317. The plug 317 includes a plug body 317a and a plug cap 317b. When the plug 317 is inserted into the medicine adding port 318, the plug body 317a is inserted into the medicine adding port 318, and the convex edge of the plug cap 317b surrounds the periphery of the medicine adding port 318. And, the plug body 317a and the medicine adding port 318 also form a ventilation gap G. The ventilation gap G is used to communicate the inside and outside of the chamber C, so that when the atomizing piece assembly 320 consumes the liquid medicine in the chamber C, external air enters the chamber C to avoid the formation of a negative pressure environment in the chamber C. The plug cap 317b can cover the upper end of the ventilation gap G to prevent the liquid medicine from overflowing, and due to the assembly gap and / or the elastic factor of the plug cap material, the ventilation gap G will not be blocked, which meets the needs of ventilation and anti-overflow.

[0082] The atomizing piece assembly 320 is a micro-mesh atomizing piece, which includes a circular ring-shaped stainless steel mesh and a piezoelectric piece. The atomizing piece assembly 320 is installed at the bottom of the recess 319 of the medicine cup 310. The inner side P1 of the atomizing piece assembly 320 faces the medicine outlet 315, and the outer side P2 is opposite to the inner side P1 and has the same orientation as the first surface S1. The atomizing piece assembly 320 is in sealed connection with the recess 319. The liquid medicine in the chamber C of the medicine cup 310 flows out of the medicine outlet 315 and is intercepted and atomized by the atomizing piece assembly 320, and the formed medicine mist is sprayed from the outer side P2. In the use state of the user, the atomizing device 300 is in an upright posture (as shown in FIG. 13), the axis of the mist outlet pipe 330 is substantially horizontal, and the atomizing piece assembly 320 is in an upright posture.

[0083] The mist outlet tube 330 is inserted into the recess 319. Specifically, a first end 331 of the mist outlet tube 330 is located within the recess 319 and is sealingly connected with the outer side P2 of the atomizing piece assembly 320; a second end 332 of the mist outlet tube 330 protrudes out of the recess 319, i.e. the second end 332 is higher than the first surface S1 of the medicine cup 310. In addition, the recess 319 is obliquely intersected with the first surface S1 of the medicine cup 310, thus making the mist outlet tube 330 obliquely protrude out of the first surface S1. Specifically, the medicine cup 310 has a first side 310L and a second side 310R, and when the medicine cup 310 is arranged in the atomizer main machine 100, the first side 310L is closer to the center of the atomizer main machine 100 than the second side 310R, and the distance between the recess 319 and the first side 310L of the medicine cup 310 is smaller than the distance between the recess 319 and the second side 310R of the medicine cup 310. In this way, although the medicine cup 310 is offset to one side of the main machine 100, the mist outlet 333 of the mist outlet tube 330 can be substantially directed towards the mouth and nose of the user.

[0084] When the recess 319 is arranged in the inclined state, the length thereof along the axial direction is greater than the length thereof perpendicular to the first surface S1. Therefore, the mist outlet tube 330 is also arranged obliquely relative to S1, and the overall length thereof is greater than the length thereof perpendicular to S1 when the overall thickness of the atomizing device 300 is unchanged. In this way, the medicine mist sprayed by the atomizing piece assembly 320 has a relatively longer diffusion distance, which is beneficial for the medicine mist to be fully diffused when reaching the mouth and nose of the user. In addition, referring to FIG. 12, the recess 319 is obliquely intersected with the first surface S1 in such a way that the top end thereof is farther away from the first side 310L of the medicine cup 310 than the bottom end thereof. The above arrangement can also make the mist outlet direction of the mist outlet 333 be away from the inner surface 201 of the other side face cover 200, reducing the condensation of the medicine mist on the surface.

[0085] In addition, the mist outlet tube 330 is provided with a blocking member 334, which forms at least one blocking portion 334a with a predetermined distance from the inner wall of the mist outlet tube 330 in at least one cross section of the mist outlet tube 330; the blocking member 334 is located outside the spray path of the atomization piece assembly 320. In the embodiment, the blocking member 334 is an annular flange, which protrudes from the bottom of the mist outlet tube 330 provided at the first end 331 to the second end 332 in the axial direction. The central passage of the annular flange can allow the drug mist to be sprayed out. The diameter of the annular flange is smaller than the diameter of the mist outlet tube 330, and the annular top surface thereof forms the blocking portion 334a. The diameter of the annular top surface is smaller than the inner diameter of the mist outlet tube 330, and there is a predetermined gap between the annular top surface and the inner wall of the mist outlet tube 330. If the user's finger enters the lumen of the mist outlet tube 330 from the second end 332, the blocking portion 334a will hinder the further insertion of the fingertip, thereby avoiding the fingertip from touching the atomization piece assembly 320. The blocking member can also have other shapes, as long as it can hinder the user's finger from entering the lumen of the mist outlet tube 330 and does not hinder the drug mist from being sprayed out. For example, the annular flange can also be replaced by an array of multiple columns, which forms an annular fence, and the top end of the fence corresponds to the blocking portion formed at a certain cross section of the mist outlet tube. The number of columns can also be less, such as any number from 1 to 4. For another example, a rib structure or other protrusions towards the center can be provided on the inner wall of the mist outlet tube 330, and the part of the rib or protrusion towards the second end 332 of the mist outlet tube 332 forms the blocking portion.
