Description

Technical Field

[0001] The present disclosure belongs to the technical field of atomizers, and particularly relates to a face mask detachable atomizer. Background Art

[0002] Inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. An atomizer is used to atomize a liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, so as to achieve the purpose of painless, rapid and effective treatment. Existing atomizers (referred to as atomizers for short) are divided into split atomizers and integral atomizers. The face mask of the split atomizer is separated from the main body, and the main body provides atomized medicine to the face mask through a pipeline. Most of the integral atomizers are handheld, mainly including a handheld atomization main body, a medicine cup and a face mask which are rigidly connected. The user needs to hold the main body to keep the face mask on the face.

[0003] One disadvantage of the above atomizer is that usually the face mask is fixedly connected to the mist outlet pipe of the medicine cup. In order to maintain a stable connection, the connection structure is either non-detachable or has a complex structure and is difficult to disassemble. Summary of the Invention

[0004] The present disclosure aims to provide a face mask detachable atomizer for replacing the face mask.

[0005] In a first aspect, a face mask detachable atomizer is provided, which includes a face mask and a main body. The face mask is detachably fixed to the main body. The face mask has a first end and a second end. The first end of the face mask is used to contact the user's face, and the second end of the face mask is used to engage with the main body. A detachable connection is formed between the face mask and the main body through a plurality of concave-convex fitting structures. The plurality of concave-convex fitting structures at least include a first concave-convex fitting structure and a second concave-convex fitting structure, and the fitting directions of the first concave-convex fitting structure and the second concave-convex fitting structure are not parallel.

[0006] In a possible implementation, a first structure and a second structure are provided on the outer surface of the second end of the face mask. The main body has a mounting surface, and a third structure and a fourth structure are provided on the mounting surface. The first structure and the third structure are used to form the first concave-convex fitting structure, and the second structure and the fourth structure are used to form the second concave-convex fitting structure. Wherein, the normal directions of the part of the outer surface of the second end where the first structure is provided and the part where the second structure is provided are not parallel, so that the concave / convex direction of the first structure is not parallel to the concave / convex direction of the second structure.

[0007] Combined with the above possible implementation, in another possible implementation, the outer surface of the second end of the face mask is a curved surface, so that the normal directions of the part of the outer surface where the first structure is provided and the part where the second structure is provided are not parallel.

[0008] Combined with the above possible implementation manners, in another possible implementation manner, the outer surface of the second end of the face mask is a V-shaped structure.

[0009] Combined with the above possible implementation manners, in another possible implementation manner, the first structure is a first mounting hole, the third structure is a first positioning post, and the first positioning post is used to be inserted into the first mounting hole to form a first concave-convex fitting structure; and / or, the second structure is a second mounting hole, the fourth structure is a second positioning post, and the second positioning post is used to be inserted into the second mounting hole to form a second concave-convex fitting structure.

[0010] Combined with the above possible implementation manners, in another possible implementation manner, the first mounting hole is a through hole, and the second mounting hole is a through hole.

[0011] Combined with the above possible implementation manners, in another possible implementation manner, the portion of the face mask for connecting to the host is an elastic structure.

[0012] Combined with the above possible implementation manners, in another possible implementation manner, the atomizer further includes a lace, and both ends of the lace are fixed to the host.

[0013] Combined with the above possible implementation manners, in another possible implementation manner, it further includes an atomization component; wherein, the host is fixed to the face mask, and the atomization component is fixed to the host.

[0014] According to the face mask detachable atomizer provided by the present disclosure, the face mask and the host form a detachable connection through a plurality of concave-convex fitting structures, and the connection structure between the face mask and the host can be more flexible (no longer limited to the connection method with the mist outlet pipe of the medicine cup), and is suitable for forming a more convenient detachable connection.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0035] 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 those of ordinary skill in the art that the present disclosure may be practiced without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present disclosure by showing examples of the present disclosure. The present disclosure is in no way limited to any specific structure and configuration presented below, but covers any modifications, substitutions, and improvements of parts, components, and connection methods without departing from the spirit of the present disclosure. Well-known structures and technologies are not shown in the drawings and the following description to avoid unnecessarily obscuring the present disclosure.

[0036] In addition, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of the embodiments of the present disclosure.

[0037] The present disclosure provides an integrated atomizer, which includes a face mask, a main body, and an atomization component. The face mask includes a first end and a second end facing opposite directions. The first end is for contacting the user's face, and the second end and the entity between the second end and the first end define a chamber for accommodating the medicated mist. The main body includes devices for providing power and / or control signals. The atomization component includes a medicine cup and an atomization sheet component disposed at the bottom of the medicine cup. Among them, the main body is fixed to the second end of the face mask, and the atomization component is fixed to the main body. The connection between the main body and the face mask may be a detachable fixed connection or a non-detachable fixed connection. In the atomizer provided by the present disclosure, the main body is directly fixed to the face mask, and the atomization component is directly fixed to the main body, so that the main body with a relatively large volume and mass is closer to the face mask, with high integration. Moreover, the main body has a relatively large volume and is suitable for being made into a shape with a relatively large surface, which can increase the degree of freedom of the connection form between it and the face mask and / or the atomization component.

[0038] In addition, the inventors also noticed the following problem: The atomization component in the atomizer needs to be connected to the medicine cup to receive the liquid medicine and also needs to transport the medicine mist to the inside of the mask. Therefore, the atomization component usually has to be provided with at least two interfaces, one interface is connected to the medicine cup, and the other interface is connected to the mask. If we want to further improve the integration of the atomizer, we usually consider reusing the existing interfaces. For example, the interface for the atomization component to output the medicine mist is not only a fluid passage but also made into a physical interface to play a role in mechanical connection. For example, this interface is usually set as 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. In this way, both the transportation of the medicine mist and the physical connection integration of the atomization component and the mask are realized. The disadvantage of this connection method is that the tubular structure usually has a small diameter and / or length, and the connection position / area with the mask is limited. Usually, for stability, this connection is set as a non-detachable fixed connection. Since the mask is non-detachable, when cleaning the mask, attention needs to be paid to preventing the cleaning liquid from spreading to areas outside the mask because there are components such as circuit boards, electrical connection contacts, batteries, or power interfaces in other areas that need to pay attention to waterproofing.

[0039] Therefore, the present disclosure also provides a mask-detachable atomizer, in which the main body and the mask are detachably connected. Devices for providing power and / or control signals are provided in the main body. The mask includes a first end and a second end facing opposite directions. The first end is used to contact the user's face, and the second end is used to connect to the main body. The mask is detachably arranged on the main body through the second end. The mask and the main body are connected to each other through a physical structure, and the atomization component is fixed to the main body. There is only a need for the medicine mist outlet of the atomization component to communicate with the mask without physical connection. Without the limitation of the physical connection between the mask and the atomization component through the medicine mist outlet, there can be a more flexible connection method between the mask and the main body. Therefore, a larger connection area or more connection structures can be set to facilitate the realization of a detachable connection structure. Therefore, the mask can be firmly connected to other structures and can also be easily removed for thorough cleaning or replacement. The atomization component can also be set in a detachable form, and the connection form between the atomization component and the main body is also more flexible.

Figure 2 For Figure 1 The exploded view of the atomizer shown in Figure 3 For Figure 1 The internal view of the mask 200 of the atomizer shown in Figure 4 For Figure 1 The isometric view of the mask 200 of the atomizer shown in Figure 5 For Figure 4 The top view of the mask 200 shown in Figure 6 For Figure 1An exploded view of the main body 100 in the atomizer shown in the figure. Figure 7 is Figure 6 A schematic structural diagram of another perspective of the main body 100 in the figure with the front shell 110b omitted.

[0041] Specifically, the atomizer includes a main body 100, a face mask 200, an atomization component 300, and a lace 400. The main body 100, the face mask 200, and the atomization component 300 are integrated into one unit, and both ends of the lace 400 are connected to the above-mentioned unit and can hold the unit on the user's face. In some embodiments, the atomization component 300 includes a medicine cup and an atomization sheet component. The medicine cup is used to hold the liquid medicine, and the atomization sheet component is used to receive and atomize the liquid medicine flowing out of the medicine cup, so that the atomized liquid medicine diffuses into the inner cavity 230 of the face mask 200. The main body 100 includes a frame 110 and necessary electrical components 120 accommodated therein. In this embodiment, the frame 110 is in the form of a shell formed by enclosing a thin sheet structure. The inside of the shell is a chamber where components can be installed. The shell has a relatively large width and a relatively small thickness. The two outer surfaces in the thickness direction of the shell are the first end face 113a facing the face mask 200 and the second end face 113b facing away from the face mask 200. In this application, the "width direction" refers to the left-right direction of the user with reference to the perspective of the user wearing the atomizer. Similarly, the up-down direction of the user is the height direction, and the front-back direction of the user is the thickness direction.

[0042] Figure 1 The orientation of the atomizer shown in the figure is the same as the orientation when the atomizer is worn on the user's face. From a top-down perspective, the frame 110 is generally V-shaped and includes a first wing 111 and a second wing 112 that are connected to each other at an obtuse angle (such as 115 degrees). Both the first wing 111 and the second wing 112 are in the shape of flat rectangular boxes. The open side of the V-shaped structure of the frame 110 is used to connect to the face mask 200. The frame 110 includes a V-shaped front shell 110b and a V-shaped rear shell 110a. Specifically, the edges of the front shell 110b and the rear shell 110a are each surrounded by a flange that protrudes in the normal direction of the main plane of the shell. The front shell 110b and the rear shell 110a are connected and fastened through the flanges to form the overall V-shaped frame 110. Among them, the rear shell 110a is closer to the user's face than the front shell 110b (from the user's perspective, the front shell 110b is in front of the rear shell 110a). One side of the inner surface of the rear shell 110a (the side facing the front shell 110b) is connected to the front shell 110b, and the outer surface side (the side facing the face mask 200) forms the first end face 113a of the frame 110 for connecting to the face mask 200.

[0043] A flat accommodation space 114 is formed inside the frame 110. The term "flat" here means that, from the user's perspective direction, the dimension of the accommodation space 114 in the front-back direction is smaller than the dimensions in the up-down direction and the left-right direction. This setting makes the center of gravity of the frame 110 close to the user's face.

[0044] Specifically, the space of the accommodation space 114 on one side of the first wing 111 is semi-open, and it is provided with a recess 116. More specifically, the part of the rear shell 110a corresponding to the first wing 111 is internally provided with a surrounding plate 115 in the shape of a rounded rectangle; while the part of the front shell 110b corresponding to the first wing 111 is provided with a window W; the window W and the surrounding plate 115 together form the recess 116 on the first 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 of the accommodation space 114 on one side of the second wing 112 is a closed space.

[0045] The electrical component 120 is installed inside the second wing 112 of the frame 110. The electrical component 120 includes a battery 121 and a control device 122, and the two are arranged in the width direction of the second wing 112.

[0046] The atomization component 300 is detachably installed on the main body 100. Specifically, the atomization component 300 is installed in the recess 116 of the frame 110. The atomization component 300 has a flat shape and is parallel to the first wing 111 when installed in the recess 116. Most of the structure of the atomization component 300 is located in the accommodation space 114 of the frame 110 (in the semi-open recess 116), and a small part of the structure protrudes from the outer surface of the front shell 110b. The mist outlet 323 of the atomization component 300 is communicated with the second through hole 117 at the bottom of the recess 116.

[0047] Reference Figure 8 , Figure 8 is Figure 1 an isometric view of the side of the mist outlet of the atomization component in the atomizer shown in. The atomization component 300 is also provided with a contact (not shown in the figure). When the atomization component 300 is installed on the frame 110, this contact of the atomization component 300 will be electrically connected to the contact 119 provided in the recess 116, so as to conduct control signals and / or electricity. The atomization component 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 component 300 is held in the recess 116 and is convenient to be taken out from the recess 116.

[0048] The mask 200 is used to cover the user's mouth and nose, and the chamber 230 inside it can keep the atomized liquid medicine mist around the user's mouth and nose. As Figures 3 to 5As shown, the first end 210 of the face mask 200 is for contacting the user's face, and the second end 220 is for connecting to the main unit 100. The second end 220 is an installation end face, which has a relatively large width (width greater than height), so it has a relatively large surface area for the main unit to adhere to. The second end 220 is provided with a rigid end plate for facilitating connection to the frame 110. Specifically, the outer side surface of the second end 220 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 a convex curved 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. 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 protrudes more forward 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. The outer surface of the second end 220 of the face mask 200 extends to both sides in its width direction, so it has a relatively large surface area, which is convenient for attaching other structures / parts. The first side portion 221 is also provided with a first through hole 224, which is used to cooperate with the mist outlet 323 of the atomization assembly 300 so that the mist generated by the atomization assembly 300 can reach the inner cavity 230 of the face mask 200.

[0049] The second end 220 of the face mask 200 has a shape adapted to the first end face 113a of the frame 110. When the face mask 200 is connected to the frame 110, the frame fits the second end 220 of the face mask 200 in the entire width direction. When the face mask 200 is connected to the main unit 100, the frame 110, the atomization assembly 300 and the electrical assembly 120 inside it are respectively arranged in contact with the first side portion 221 and the second side portion 222 of the face mask 200 (only separated by the wall plate of the rear shell 110a in the middle). In this way, both the electrical assembly 120 and the atomization assembly 300 can be close to the face mask 200, and most of the structure of the frame 110 is also close to the face mask 200, so that the centers of gravity of the main unit 100 and the atomization assembly 300 can be closer to the face mask 200. The closer the centers of gravity of the main unit 100 and the atomization assembly 300 are to the face mask 200, the smaller the downward moment generated by the gravity they receive, and the smaller the force required to keep the atomizer on the user's face.

[0050] In some alternative embodiments, the frame 110 may not be provided. The atomization assembly 300 and the electrical assembly 120 can be directly connected to the second end 220 of the face mask 200. In some other alternative embodiments, the atomization assembly 300 and the electrical assembly 120 can be directly connected to the second end 220 of the face mask 200. The frame 110 only includes a front shell 110b, and the front shell 110b is used to cover the atomization assembly 300 and the electrical assembly 120.

[0051] In some alternative embodiments, the surface of the atomization component 300 is flush with the outer surface of the frame 110. In some other alternative embodiments, the atomization component 300 can be fully installed inside the frame 110 in a detachable or non-detachable manner (the front shell 110b of the frame 110 does not need to be provided with a window W), and only the liquid filling port needs to be kept communicable with the outside world.

[0052] In some alternative implementations, the surface of the second end can also be other outwardly convex curved surfaces, such as a curved surface that is entirely arc-shaped, that is, the first side portion 221 and the second side portion 222 themselves have a certain curvature and the transitional connection between the two is smoother, rather than forming a corner-shaped middle portion 223.

[0053] In some alternative embodiments, the angle between the first side portion 221 and the second side portion 222 of the second end 220 in the face mask 200 can also be greater than or less than 115 degrees, such as 110 degrees, 120 degrees, 130 degrees or 150 degrees, as long as it is between 90 degrees and 150 degrees.

[0054] Further reference Figure 9 and Figure 10 。 Figure 9 For Figure 6 a schematic structural view of the front shell in another direction in Figure 10 is a cross-sectional view of the atomizer with the atomization component 300 omitted, in which the position relationship between the main body 100 and the face mask 200 is just when they are separated, 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 body 100 are detachably connected through a plurality of concave-convex fitting structures, and the plurality of concave-convex fitting structures at least include a first concave-convex fitting structure and a second concave-convex fitting structure, and the fitting directions of the first concave-convex fitting structure and the second concave-convex fitting structure are not parallel. When the fitting directions of the first concave-convex fitting structure and the second concave-convex fitting structure are not parallel, the cooperation between the concave structure and the convex structure does not have to be a tight fit to achieve a stable connection between the face mask and the main body, because when the face mask and the main body are separated, during the process of the convex structure being pulled out from the concave structure, the scanning envelope surface of the outer contour of the convex structure will interfere with the inner surface of the concave structure, which is equivalent to the inner surface of the concave structure forming a limit for the convex structure. In this way, both the stable connection between the face mask and the main body is achieved, and there is no need for very precise dimensional fit and / or geometric tolerance between the concave-convex fitting structures, which is beneficial to improving the error tolerance rate and reducing the processing cost.

[0055] 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 overall shape of the outer surface of the second end 220 is a V-shaped bent surface, which extends in the width direction as a whole, and specifically includes 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 provided on the first side portion 222, and the second mounting hole 226 is provided on the second side portion 222. The first side portion 221 and the second side portion 222 are each substantially planar, so their normal directions are also non-parallel. The axes of the first mounting hole 225 and the second mounting hole 226 are both along the normal direction.

[0056] 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 parts of the first end face 113a corresponding to the first wing 111 and the second wing 112. The first wing 111 and the second wing 112 are neither coplanar nor parallel, but have a certain included angle, so the first positioning post 10 and the second positioning post 20 also have a non-parallel positional relationship. The first mounting hole 225 is provided on the first side portion 221 of the second end 220, and the second mounting hole 226 is provided on the second side portion 222 of the second end 220.

[0057] When the frame 110 is connected to the second end 220, the first positioning post 10 is inserted into the first mounting hole 225 of the face mask 200 to form a first concave-convex fitting structure; the second positioning post 20 is inserted into the second mounting hole 226 of the face mask 200 to form a second concave-convex fitting structure. Moreover, the first mounting hole 225 and the second mounting hole 226 are through holes, and the tops of the first positioning post 10 and the second positioning post 20 will extend into the interior of the face mask 200. In this way, when it is necessary to separate the main unit 100 and the face mask 200, the user can push the tops of the first positioning post 10 and the second positioning post 20 successively from the interior of the face mask 200 to separate the fitting structure. The second end 220 is a rigid end plate, and relative to the soft first end 210, it is easier to set connection structures that need to withstand a certain amount of force. Specifically, the face mask 200 is a double-layer structure. The side of the second end 220 located inside the face mask 200 is a rigid inner plate 240, and the outside is a soft rubber of the same material as the first end 210. In this way, the second end 220 has a certain rigidity as a whole and is suitable as an attachment base for other structures. The soft layer can be integrally formed with other parts of the face mask.

[0058] In addition, when the main unit 100 and the face mask 200 are separated, they move away from each other in the front - rear direction with the user as a reference. The direction in which they move away from each other is not parallel to the axial direction of the first positioning post 10 / the second positioning post 20. In this way, interference will be formed between the circumferential surface of the positioning post in the fitting structure and the side wall of the mounting hole. This interference will prevent their unexpected separation because a sufficiently large force or a proper separation operation is required to separate them. In this embodiment, the second end 220 of the face mask 200 has a relatively large overall width. Even if the second end 220 is a rigid plate structure, it will have a certain elasticity. Therefore, when the user tries to separate them with force, the second end 220 will undergo a certain amount of opening deformation so that the first positioning post 10 and the second positioning post 20 can be disengaged from the mounting holes. In addition, the first positioning post 10 and the second positioning post 20 are distributed on two flanks in the width direction of the frame 110. The distance between them is relatively large. When only the first positioning post 10 is pressed first, the entire main unit 100 will rotate relative to the face mask 200 with the second positioning post 20 as a reference point, and the first positioning post 10 can be easily disengaged from the first mounting hole 225. After the first positioning post 10 is separated from the first mounting hole 225, then press the second positioning post 20 to disengage it from the second mounting hole 226. Through the above - mentioned proper separation operation, the force required for the separation process is relatively small.

[0059] In addition, the lanyard 400 is installed at both ends of the frame 110 in the main unit 100, and there is no direct connection between the face mask 200 and the lanyard 400. When replacing the face mask 200, there is no need to replace the lanyard 400. In this way, when it is necessary to discard the face mask 200 and replace it with a new one, fewer structures need to be discarded. In addition, the lanyard 400 can directly bind the main unit 100. When the lanyard 400 is installed on the face mask 200, because the face mask 200 is relatively soft and the mass of the main unit 100 is relatively large, the face mask 200 may tend to sag.

[0060] Moreover, the entire atomization assembly 300 can be conveniently removed from the main unit 100, making the operations of adding liquid medicine and cleaning the medicine cup more convenient. If the atomization assembly 300 is damaged, only the new atomization assembly 300 needs to be replaced, and there is no need to scrap the entire nebulizer.

[0061] In some alternative embodiments, a convex structure, such as a positioning post, can also be provided on the second end of the face mask 200; correspondingly, a concave structure, such as a mounting hole, is provided on the main unit 100. In some other alternative embodiments, more concave - convex fitting structures can be further provided, such as 3 or 4. Among multiple concave - convex fitting structures, at least two of the fitting directions of the concave - convex fitting structures should not be parallel.

[0062] In some alternative embodiments, the outer surface of the second end 220 may also be arc-shaped (when viewed from above), and the surface of the host 100 that engages with the second end 220 also has a matching shape. A plurality of mounting holes are provided on the outer surface of the second end 220. In the width direction, any two parts of the second end 220 are not parallel, so the recessed directions of two mounting holes provided at any two parts in the width direction are not parallel. Correspondingly, a plurality of positioning posts are provided on the surface of the host 100 that engages with the second end 220, and the plurality of positioning posts protrude (radially), and the positioning posts are in a non-parallel relationship with each other.

[0063] As described above, the above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
