Description

Technical Field

[0001] The utility model generally relates to the technical field of medical devices, and particularly relates to a portable atomizer. Background Art

[0002] Atomization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. An atomizer is used to atomize the 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. The existing atomizers are divided into three types: ultrasonic atomizers, compressed atomizers and micro-mesh atomizers. The compressed atomizer has a large volume and high noise, and is not suitable for moving; while the ordinary ultrasonic atomizer has too large ultrasonic fog particles, which is not conducive to human absorption and treatment. Therefore, the micro-mesh atomizer with low noise, light structure and small atomized particles is favored by consumers.

[0003] For example, a handheld micro-mesh atomizer provided by the existing patent (application number: CN201620942472.3) includes an atomization unit and a main control unit, and the atomization unit and the main control unit are detachably arranged; the atomization unit includes a medicine storage part, a micro-mesh atomization sheet and a nozzle. An atomization port is arranged on the front side of the medicine storage part, and the nozzle extends obliquely upward from the atomization port; the nozzle is provided with a nozzle hole, a nozzle port and a nozzle cavity. The nozzle port is axially aligned with the atomization port, and the micro-mesh atomization sheet is arranged between the nozzle port and the atomization port and is axially sealed to the nozzle through a sealing ring. The liquid medicine is atomized by the micro-mesh atomization sheet and then enters the nozzle cavity from the nozzle port and diffuses outward. The nozzle holes are arranged at intervals on the rear side of the nozzle, so as to laterally communicate the nozzle cavity with the outside.

[0004] The micro-mesh atomization sheet includes a micro-mesh and an atomization sheet. The atomization sheet atomizes the liquid medicine into particles through ultrasonic waves, and the atomized particles are extruded from the micro-mesh with small apertures to form an aerosol with smaller particles, so as to facilitate the absorption of patients. However, since the apertures of the micro-mesh are small, if it is not cleaned and replaced frequently, it is very easy to cause blockage and affect the use; moreover, when different medicines are used in the atomizer, the medicines remaining on the micro-mesh are likely to cause cross-mixing of medicines and affect the efficacy. However, the micro-mesh atomization sheet of the above solution is axially sealed to the nozzle, making it inconvenient to disassemble the micro-mesh for cleaning and replacement.

[0005] Therefore, how to make the micro-mesh atomization sheet of the atomizer convenient for disassembly and replacement has become the main problem to be solved at present. Summary of the Invention

[0006] In view of the above defects or deficiencies in the prior art, it is desired to provide a portable atomizer. By separately arranging the micro-mesh filter sheet and the ultrasonic atomization sheet, the micro-mesh filter sheet is arranged on the mask and can be installed and disassembled on the installation table together with the mask. Without affecting the function of the atomizer, the installation and disassembly of the micro-mesh filter sheet are more convenient, so as to facilitate cleaning or replacement.

[0007] The effects of the present utility model are achieved as follows:

[0008] This application provides a portable atomizer, comprising:

[0009] An atomizer body, the atomizer body includes a medicine cup part, the medicine cup part is a hollow box-shaped structure, the internal space thereof includes a medicine storage cavity for storing medicine, a columnar mounting platform is arranged on the front side of the medicine cup part, a hollow is formed in the middle of the mounting platform to form a spray port, the spray port communicates with the medicine storage cavity, and an ultrasonic atomization sheet is arranged along the radial direction in the spray port, and the ultrasonic atomization sheet is configured to atomize the medicine in the medicine storage cavity and transmit the atomized particles into the spray port;

[0010] A face mask, the face mask is a cover-shaped structure, the hollow part thereof forms a connection cavity, the rear end of the face mask extends backward to form a connection part, and the connection part is sleeved on the mounting platform through the connection cavity; a micro-mesh filter sheet is arranged along the radial direction in the connection cavity, the micro-mesh filter sheet faces the spray port and is configured to extrude the atomized particles to form aerosol particles with a smaller diameter; and, the connection part is detachably arranged on the mounting platform, so that the micro-mesh filter sheet can be disassembled and replaced together with the face mask.

[0011] Further, the connection part and the mounting platform are detachably connected through a clamping structure, and the clamping structure includes a clamping head and a limiting groove, the clamping head is arranged on one of the connection part and the mounting platform, and the limiting groove is opened on the other of the connection part and the mounting platform. This not only makes the installation and disassembly between the connection part and the mounting platform relatively convenient, but also enables the two to remain relatively fixed after the connection part is connected to the mounting platform, and the connection strength is higher.

[0012] Further, a plurality of clamping heads distributed along the circumferential direction are arranged on the outer wall of the mounting platform, a plurality of limiting parts distributed along the circumferential direction are arranged on the inner wall of the connection part, and the limiting groove is recessed in the limiting part. This makes the connection strength between the connection part and the mounting platform better.

[0013] Further, taking the axial direction of the connection part as a reference, a plurality of limiting grooves are arranged to open on one side facing the clockwise and / or clockwise circumferential direction, so that when the face mask rotates clockwise or counterclockwise, the clamping head can be inserted into or disengaged from the limiting part from the opening. This enables the locking or separation between the face mask and the medicine cup part to be achieved only by rotating the face mask clockwise or counterclockwise to make the clamping head be inserted into or disengaged from the limiting part, further improving the convenience of installing and disassembling the face mask.

[0014] Furthermore, the medicine cup part has a split structure, including a housing on the outside and a measuring cup on the inside. Both the housing and the measuring cup are box-shaped structures with openings on the upper side. The installation platform is arranged on the housing, and the space inside the housing forms a connection groove. The measuring cup is detachably connected to the housing through the connection groove, and the space inside the measuring cup forms a medicine storage cavity. The front side of the measuring cup is provided with an opening in a hollowed-out manner. When the measuring cup is connected to the housing, the opening is directly opposite the spray nozzle. This not only facilitates the separate disassembly of the measuring cup for cleaning, but also when the patient uses multiple medications, multiple measuring cups can be prepared to hold different medications respectively, thus facilitating the replacement of the measuring cup to use different medications and effectively avoiding the mixing of different medications from affecting the efficacy of the medications.

[0015] Furthermore, an adjusting member is hinged to the rear side of the medicine cup part, and the adjusting member can be turned back and forth relative to the medicine cup part. The top end of the medicine cup part is covered with a cover plate. The front end of the cover plate is hinged to the front side of the top end of the medicine cup part, and the rear end of the cover plate is connected to the adjusting member through a first snap structure. The snap structure includes a first hook and a first slot. The first hook is arranged on one of the rear end of the cover plate and the top end of the adjusting member, and the first slot is arranged on the other of the rear end of the cover plate and the top end of the adjusting member. By covering the cover plate on the medicine cup part, it effectively avoids the spilling of medications during the use of the nebulizer. Moreover, the connection between the cover plate and the adjusting member through the snap structure makes the adjustment operation of opening and closing the cover plate relatively simple.

[0016] Furthermore, the nebulizer body further includes a main control part, and the medicine cup part is detachably connected to the main control part. A connection platform is arranged at the top end of the main control part. The bottom end of the medicine cup part extends downward to form a sleeve-shaped socket part, and the space inside the socket part forms a socket groove. The medicine cup part is socketed on the connection platform through the socket groove, and the main control part is configured to provide power. This enables the medicine cup part without waterproof requirements to be separately disassembled for cleaning, thus solving the risk of the main control part getting electrically leaked when encountering water and making it more convenient to use.

[0017] Furthermore, several pressing plates extend upward from the side wall of the main control part. The pressing plates have the ability of elastic deformation and there is a certain distance between the pressing plates and the connection platform. A second snap structure is arranged between the pressing plates and the inner wall of the socket part. The second snap structure includes a second hook and a second slot. The second hook is arranged on one of the inner wall of the socket part and the top end of the pressing plate, and the second slot is opened on the other of the inner wall of the socket part and the top end of the pressing plate. This makes the connection strength between the pressing plates and the socket part better, and the second hook can be snapped into or disengaged from the second slot through the elastic deformation of the pressing plates, making the installation and disassembly operations between the pressing plates and the socket part relatively simple.

[0018] Furthermore, several avoidance openings are provided on the socket part, and the avoidance openings are directly opposite the pressing plates. The avoidance openings are configured to allow the user to press the pressing plates. This facilitates the user to adjust the pressing plates and makes the installation and disassembly operations between the main control part and the medicine cup part more simple.

[0019] Furthermore, a positioning structure is provided between the socket part and the connecting platform. The positioning structure includes a vertically arranged positioning protrusion and a positioning groove. The positioning protrusion is provided on one of the inner wall of the socket part and the side wall of the connecting platform, and the positioning groove is formed on the other of the inner wall of the socket part and the side wall of the connecting platform. During the installation and disassembly of the medicine cup part, guided by the positioning protrusion and the positioning groove, the installation and disassembly process of the medicine cup part can be more stable and accurate, and the connection strength between the medicine cup part and the main body part can be higher.

[0020] Furthermore, the front and rear side walls of the connecting platform are both recessed to form positioning grooves, and the front and rear inner walls of the socket part correspondingly protrude with positioning protrusions. And the width of the positioning groove on the front side of the connecting platform is longer than that on the rear side. When the medicine cup part is inserted, if the medicine cup part is reversed, the positioning protrusion cannot be stuck into the positioning groove, thus reminding the user that the medicine cup part is inserted reversely and making the assembly of the medicine cup part more accurate.

[0021] For the portable atomizer provided by the present application, by separately arranging the micro-mesh filter sheet and the ultrasonic atomization sheet, the micro-mesh filter sheet is arranged on the face mask and can be installed and disassembled on the installation platform together with the face mask. Without affecting the function of the atomizer, the installation and disassembly of the micro-mesh filter sheet are more convenient, so as to facilitate cleaning or replacement.

Detailed implementation manners

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0036] Please refer to the attached Figures 1-11 , the embodiment of the present application provides a portable atomizer, including:

[0037] The atomizer body 1, the atomizer body 1 includes a medicine cup part 2, the medicine cup part 2 is a hollow box-shaped structure, the inner space thereof includes a medicine storage cavity 201 for storing medicine, a columnar mounting table 210 is arranged on the front side of the medicine cup part 2, a nozzle 211 is formed by hollowing out the middle of the mounting table 210, the nozzle 211 communicates with the medicine storage cavity 201, and an ultrasonic atomization sheet 220 is arranged along the radial direction in the nozzle 211, and the ultrasonic atomization sheet 220 is configured to atomize the medicine in the medicine storage cavity 201 and transmit the atomized particles into the nozzle 211;

[0038] The face mask 3 is in a shape of a cover, and its hollow part forms a connection cavity 301. The rear end of the face mask 3 extends backward to form a connection part 310, and the connection part 310 is sleeved on the mounting table 210 through the connection cavity 301. A micro-mesh filter 320 is arranged radially in the connection cavity 301. The micro-mesh filter 320 faces the nozzle 211 and is configured to extrude the atomized particles to form aerosol particles with a smaller diameter. Moreover, the connection part 310 is detachably arranged on the mounting table 210, so that the micro-mesh filter 320 can be disassembled and replaced together with the face mask 3.

[0039] In this embodiment, when the patient installs the face mask 3 on the medicine cup part 2 and starts the atomizer body 1, the ultrasonic atomizing sheet 220 is powered on and vibrates to preliminarily atomize the liquid medicine in the medicine storage cavity 201 into particles and send them into the nozzle 211. At this time, the patient covers the mouth and nose with the face mask 3 and inhales the medicine, so that a pressure difference is generated between the connection cavity 301 and the nozzle 211. The atomized particles in the nozzle 211 move towards the connection cavity 301 and are squeezed into the micro-mesh filter 320 between the connection cavity 301 and the nozzle 211. Since the pore diameter of the micro-mesh filter 220 is small, the atomized particles can form aerosol particles with a smaller diameter after being extruded from the micro-mesh filter 320, which is more conducive to the patient's absorption.

[0040] Among them, by separately arranging the micro-mesh filter 320 and the ultrasonic atomizing sheet 220, the micro-mesh filter 320 is arranged on the face mask 3 and can be installed and disassembled on the mounting table 210 together with the face mask 3. Without affecting the function of the atomizer, the installation and disassembly of the micro-mesh filter 320 are more convenient, so as to facilitate cleaning or replacement.

[0041] Among them, preferably, the micro-mesh filter 320 is fixed to the connection part 310 by ultrasonic welding, so that the connection strength between the micro-mesh filter 320 and the connection part 310 is high and the sealing performance is good, and the face mask 3 becomes a disposable component. The micro-mesh filter 320 is replaced together with the disassembly of the face mask 3, thus effectively solving the problem of blockage of the micro-mesh filter 320 and effectively avoiding the risk of cross-infection caused by multiple uses of the face mask 3. Of course, in other embodiments of the present application, the micro-mesh filter 320 and the connection part 310 can also be fixed by means of glue connection or the like, or can be detachably connected by means of screw connection, snap connection, magic tape, etc.

[0042] Among them, preferably, the micro-mesh filter 320 is a mesh with thousands of holes with a diameter of 3 microns, so that the aerosol particles extruded from the micro-mesh filter 320 are small enough to be conducive to the patient's absorption.

[0043] Please refer to the appendix Figures 3-5, in some embodiments of the present application, the connecting portion 310 and the mounting table 210 are detachably connected through a clamping structure. The clamping structure includes a clamping head 212 and a limiting groove 311. The clamping head 212 is provided on one of the connecting portion 310 and the mounting table 210, and the limiting groove 311 is formed on the other of the connecting portion 310 and the mounting table 210.

[0044] In this embodiment, the connecting portion 310 and the mounting table 210 are fixed through the clamping head 212 and the limiting groove 311, which not only makes the installation and disassembly between the two more convenient, but also enables the two to remain relatively fixed after the connecting portion 310 is connected to the mounting table 210, and the connection strength is higher.

[0045] Of course, in other embodiments of the present application, the connecting portion 310 and the mounting table 210 can also be detachably connected by means of threaded connection, magic tape, etc.

[0046] Please refer to the appendix Figures 3-5 , in some embodiments of the present application, a plurality of clamping heads 212 distributed circumferentially are provided on the outer wall of the mounting table 210, and a plurality of limiting portions 330 distributed circumferentially are provided on the inner wall of the connecting portion 310. The limiting groove 311 is recessed in the limiting portion 330.

[0047] In this embodiment, by providing a plurality of clamping heads 212 on the outer wall of the mounting table 210 and providing a limiting portion 330 on the inner wall of the connecting portion 310 for clamping and cooperating with the clamping head 212, the connection strength between the connecting portion 310 and the mounting table 210 is relatively good.

[0048] Among them, preferably, three equally spaced clamping heads 212 are provided on the outer wall of the mounting table 210, and three corresponding limiting portions 330 are provided on the inner wall of the connecting portion 310. By providing multiple groups of clamping heads 212 and limiting grooves 311 for clamping and cooperating, the connection strength between the two is further improved. Of course, in other embodiments of the present application, the number of clamping heads 212 on the outer wall of the mounting table 210 can also be two, four, etc.

By simply rotating the mask 3 clockwise or counterclockwise to make the clamping head 212 engage with or disengage from the limiting portion 330, the locking or separation between the mask 3 and the medicine cup portion 2 can be realized, further improving the convenience of installing and disassembling the mask 3.

[0050] Preferably, with the axis of the connecting portion 310 as a reference, a plurality of limiting grooves 311 are arranged to open towards the clockwise circumferential side. Please refer to the appendix Figure 5 When installing the mask 3, first buckle the limiting portion 330 on the connecting portion 310 into the gap between the chucks 212 on the mounting table 210 to perform preliminary positioning between the connecting portion 310 and the mounting table 210; then rotate the mask 3 clockwise to drive the limiting portion 310 on the connecting portion 310 to rotate clockwise, and enable the chuck 212 to be stuck into the limiting groove 311 along the opening on one side of the limiting portion 310 and abut against the groove wall on the other side, so as to realize the relative fixation between the chuck 212 and the limiting portion 310, and further enable the mask 3 to be stably connected to the medicine cup portion 2; conversely, the disassembly of the mask 3 can also be realized.

[0051] Please refer to the appendix Figures 6-8 In some embodiments of the present application, the medicine cup portion 2 is a split structure, including an outer shell 230 and an inner measuring cup 240. Both the shell 230 and the measuring cup 240 are box-shaped structures with openings on the upper side. The mounting table 210 is arranged on the shell 230. The space inside the shell 230 forms a connecting groove 231.

The first hook 261 is arranged on one of the rear end of the cover plate 250 and the top end of the adjusting member 260, and the first slot 251 is arranged on the other of the rear end of the cover plate 250 and the top end of the adjusting member 260.

[0054] In this embodiment, by covering the medicine cup part 2 with the cover plate 250, it effectively avoids the spilling of medicine during the use of the atomizer; moreover, the cover plate 250 and the adjusting member 260 are connected by a snap structure. In the closed state, the first hook 261 snaps into the first slot 251, so that the cover plate 250 and the medicine cup part 2 remain relatively fixed; when switched to the open state, only need to press the lower end of the adjusting member 260, the adjusting member 260 flips and drives the first hook 261 to disengage from the first slot 261, so that the cover plate 250 can be flipped relative to the medicine cup part 2 again; making the adjustment operation of opening and closing the cover plate 250 relatively simple.

[0055] Among them, preferably, the first hook 261 is arranged at the upper end of the adjusting member 260, and the front end of the cover plate 250 is correspondingly provided with the first slot 251. The adjusting member 260 is hinged to the rear end of the measuring cup 240 through a horizontally arranged rotating shaft, and the rear end of the housing 230 is hollowed out with an opening for the user to operate the adjusting member 260 on the measuring cup 240. A first return spring 262 is further arranged between the lower end of the adjusting member 260 and the measuring cup 240. The first return spring 262 pushes the lower end of the adjusting member 260, so that the upper end of the adjusting member 260 always has a tendency to flip forward, and further drives the first hook 261 to always have a tendency to snap into the first slot 251, so that in the closed state, the cover plate 250 can be stably fixed to the upper end of the medicine cup part 2.
