The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] See also Figures 1 to 10 The nasal atomization device of the embodiment of the present application includes an atomization component 100, a nasal nozzle component 200 that is magnetically connected to the atomization component 100, the atomization component 100 includes a shell 300, and a ceramic atomization component 400 and an airflow adjustment component 500 arranged in the shell 300. The top of the shell 300 is provided with an air cavity 301 that is nested and docked with the guide body 21 of the nasal nozzle component 200. The ceramic atomization tube 41 of the ceramic atomization component 400 is provided below the corresponding air cavity 301 and docked with the corresponding air cavity 301. An airflow adjustment component is provided next to each ceramic atomization component 400, and the air adjustment tube 51 of the airflow adjustment component 500 is connected to the corresponding air cavity 301, wherein,

[0040] The nasal nozzle assembly 200 is used to inhale air along the ceramic atomizing tube 41 and the air regulating tube 51 during nasal inhalation, and to inhale the mist in the air cavity 301 upwards;

[0041] The ceramic atomizing assembly 400 is used to atomize the drug atomized material placed in the ceramic atomizing tube 41 and the air flow inhaled along the ceramic atomizing tube 41 into mist, and to inject the atomized mist into the air cavity 301;

[0042] The air flow regulating assembly 500 is used to control the opening and closing of a plurality of air flow regulating holes 511 provided on the air regulating pipe 51 to control the air flow injected into the air cavity 301 along the air regulating pipe 51 so that the mist concentration in the air cavity 301 is at a preset concentration.

[0043] In the above-mentioned nasal inhalation atomization device, a ceramic atomization component 400 is used to heat and atomize the drug atomizer, so that the atomization is sufficient and the atomization efficiency is improved; by setting an airflow adjustment component 500, the airflow injected into the air cavity 301 along the air adjustment tube 51 is controlled, that is, after the ceramic atomization component 400 atomizes the drug atomizer and the airflow into mist, the amount of airflow injected into the air cavity 301 along the air adjustment tube 51 is controlled. By controlling the amount of injected airflow, the mist concentration in the air cavity 301 is made to be at a preset concentration, thereby solving the problems of insufficient atomization of the nasal inhalation equipment used for treatment and uneven concentration of the drug mist after atomization.

[0044] To achieve the quick docking assembly of the nasal nozzle assembly 200 and the atomizer assembly 100, refer to Figures 2 to 3 In one embodiment, a groove 302 is provided at the top of the housing 300, and a mist outlet 303 is provided at a position where the groove 302 is opposite to the air cavity 301. The groove 302 is also provided with a plurality of first mounting grooves 304. The nasal nozzle assembly 200 is provided with a second mounting groove 201 at a position opposite to the first mounting groove 304. Magnets 600 are provided in both the first mounting groove 304 and the second mounting groove 201.

[0045] The corresponding magnets 600 are magnetically attracted to each other, so that the nasal nozzle assembly 200 received in the groove 302 is magnetically quickly connected to the atomizer assembly 100.

[0046] In this embodiment, the nasal suction nozzle assembly 200 is quickly positioned relative to the atomizer assembly 100 by limiting the groove 302; and then the nasal suction nozzle assembly 200 and the atomizer assembly 100 are quickly docked and assembled by the magnetic attraction of the corresponding magnet 600; it can be understood that when the nasal suction nozzle assembly 200 needs to be disassembled relative to the atomizer assembly 100, it is only necessary to pull the nasal suction nozzle assembly 200 apart from the atomizer assembly 100, that is, to separate the corresponding magnets 600 relatively, and then quickly disassemble the nasal suction nozzle assembly 200 and the atomizer assembly 100.

[0047] When the nasal nozzle assembly 200 is magnetically connected to the atomizer assembly 100, the guide body 21 passes through the corresponding mist outlet hole 303 and extends into the corresponding air cavity 301, so that the nasal nozzle assembly 200 can inhale the mist in the air cavity 301.

[0048] It can be understood that with such a configuration, the nasal nozzle assembly 200 and the atomizer assembly 100 can be quickly positioned by accommodating and limiting the groove 302; at the same time, the nasal nozzle assembly 200 and the atomizer assembly 100 are assembled and docked by magnetic attraction, and the atomizer assembly 100 and the nasal nozzle assembly 200 are easy to assemble and disassemble, so that the atomizer assembly 100 is convenient for adding or replacing drug atomizer, and after adding or replacing drug atomizer, it can be quickly assembled and used.

[0049] To achieve atomization of drug aerosol, refer to Figure 2 、 Figures 4 to 7 In some embodiments, the ceramic atomizer assembly 400 further includes a storage core 42 and a one-way air valve 43. The ceramic atomizer tube 41 is provided with an upper tube cavity 411 and a lower tube cavity 412. The upper tube cavity 411 and the lower tube cavity 412 are connected through a plurality of air holes 413. The end of the upper tube cavity 411 away from the lower tube cavity 412 is connected to the air cavity 301. The storage core 42 is provided in the upper tube cavity 411. The end of the lower tube cavity 412 away from the upper tube cavity 411 is connected to the air inlet 305 provided in the shell 300. The one-way air valve 43 is provided in the lower tube cavity 412.

[0050] The storage core 42 is used to accommodate the drug aerosol.

[0051] In this embodiment, the storage core 42 includes adsorption cotton, and the drug aerosol to be atomized is a solid drug, and the drug aerosol is attached to the adsorption cotton; in this embodiment, when replacing or adding the drug aerosol, the storage core 42 with the drug aerosol attached can be replaced to achieve the replacement or addition of the drug, or the corresponding drug aerosol can be directly added to the storage core 42 so that the added drug aerosol is placed in the storage core 42, for example: by setting a plurality of honeycomb holes on the adsorption cotton corresponding to the storage core 42, the drug aerosol is placed in the honeycomb holes, thereby achieving the storage of the drug aerosol.

[0052] The one-way air valve 43 is used to allow the air flow injected into the lower tube cavity 412 through the air inlet hole 305 to flow to the upper tube cavity 411 in a one-way direction.

[0053] In this embodiment, the one-way air valve includes but is not limited to a silicone one-way valve. In this embodiment, a silicone one-way valve is used. When the air flow enters the lower tube cavity 412 of the ceramic atomization tube 41 from the air inlet 305, the silicone one-way valve is turned on, so that the air flow can be injected into the ceramic atomization tube 41 from bottom to top, so as to generate mist after heating the drug atomizer. When nasal inhalation and heating are stopped, the mist in the ceramic atomization tube 41 will flow downward due to the lack of upward suction. Due to the reverse cut-off function of the silicone one-way valve, the mist cannot flow back through the silicone one-way valve, so that the mist is retained in the upper tube cavity 411, thereby reducing the loss of atomized mist.

[0054] The ceramic atomizing tube 41 is used for allowing inhaled air to flow through, and atomizes the drug atomizer contained in the storage core 42 and the air flow flowing through the upper tube cavity 411 into mist, and guides the mist to the air cavity 301.

[0055] In this embodiment, the direction of the atomized air flow can be referred to Figure 4 As shown by the two dotted lines in the middle.

[0056] It can be understood that with such a setting, the drug atomizer and the airflow are atomized into mist through the ceramic atomizer tube 41, so that the atomizer is fully atomized. At the same time, by setting the one-way air valve 43, the main airflow direction can only be from bottom to top, reducing the loss of the atomized mist flowing out of the air inlet 305, thereby enhancing the atomization efficiency of the nasal atomizer device.

[0057] To install the ceramic atomizing assembly 400 and the airflow regulating assembly 500, refer to Figure 2 In some embodiments, the shell 300 includes a lower base 31 and an upper cover 32. The lower base 31 is provided with two card slots 311, and the upper cover 32 is provided with an upper cover arc groove 321 adapted to the card slot 311. The ceramic atomization tube 41 is fixed in the card slot 311 and locked by the upper cover arc groove 321.

[0058] It should be noted that, in this embodiment, the atomization assembly 100 is provided with two groups of ceramic atomization assemblies 400 and airflow adjustment assemblies 500. A ceramic atomization assembly 400 and a corresponding airflow adjustment assembly 500 constitute an atomization unit. The two atomization units can be switched to work. At the same time, the nasal suction nozzle assembly 200 is docked with the two atomization units. The mist generated by the two atomization units can be transmitted to the user's nose through the nasal suction nozzle assembly 200, thereby realizing nasal atomization treatment. By setting two groups of switchable atomization units, the use effect of the nasal atomization device is ensured, and the use time of the nasal atomization device is extended.

[0059] In order to adjust the air flow in the air cavity 301 so that the mist concentration in the air cavity 301 is maintained at a preset level, refer to Figure 2 、 Figure 4 、 Figure 5 as well as Figure 8 In some embodiments, an air flow regulating assembly 500 is provided on the side of each card slot 311, and the air flow regulating assembly 500 further includes an air regulating pipe mounting seat 52, an air regulating plug 53, a transmission unit 54 and a driving unit 55. The air regulating pipe mounting seat 52 is fixed on the side wall of the card slot 311, and the air regulating pipe 51 is fixed on the air regulating pipe mounting seat 52. The end of the air regulating pipe 51 away from the air flow regulating hole 511 is also connected to the air cavity side flow hole 306 communicating with the air cavity 301 through a bend pipe joint 56. The air regulating plug 53 is movably embedded in the air flow channel 512 of the air regulating pipe 51 and can move in the air flow channel 512. The end of the air regulating plug 53 away from the air regulating pipe 51 is connected to the transmission unit 54, and the transmission unit 54 is transmission-connected to the driving unit 55.

[0060] The driving unit 55 is used to drive the transmission unit 54 to drive the air regulating plug 53 to move in the air flow channel 512;

[0061] In this embodiment, the transmission unit 54 that meets the requirements for the transmission air regulating plug 53 to insert into or exit the air flow channel 512 is suitable for the transmission unit 54 of the embodiment of the present application, for example: the transmission unit 54 can be a ball screw transmission pair; at the same time, the drive unit 55 that meets the requirements for driving the transmission unit 54 to drive the air regulating plug 53 to move is suitable for the drive unit 55 of the embodiment of the present application, for example: the drive unit 55 can be a drive motor. In some optional embodiments, the transmission unit 54 adopts a ball screw transmission pair, the drive unit 55 is a drive motor, and the air regulating plug 53 is connected to the ball nut of the ball screw transmission pair, and is also slidably connected to the guide rod of the ball screw transmission pair, and the ball screw of the ball screw transmission pair is transmission-connected to the drive motor, and the drive motor drives the ball screw to rotate to drive the ball nut to slide along the ball screw, thereby driving the air regulating plug 53 to move following the ball nut. At the same time, the guide rod guides the air regulating plug 53 so that the air regulating plug 53 moves smoothly and then inserts into or exits the air flow channel 512.

[0062] The air regulating plug 53 is used to block or open the corresponding air flow regulating hole 511 when moving in the air flow channel 512 to control the air flow injected into the air cavity 301 along the air regulating pipe 51.

[0063] It can be understood that with such a configuration, after the ceramic atomizing tube 41 is working, as the drug atomizer decreases, the driving unit 55 drives the transmission unit 54 to drive the gas regulating plug 53 to push upward, so that the gas regulating plug 53 blocks the multiple air flow regulating holes 511 on the gas regulating tube 51 in sequence, thereby controlling the atomization flow rate of the atomizer, that is, maintaining the mist concentration in the air cavity 301 at a preset concentration. It should be understood that at the beginning of atomization, because there is more drug atomizer in the ceramic atomizing tube 41, the corresponding concentration after atomization is thicker, and by opening multiple The airflow regulating hole 511 allows a large amount of airflow to be inhaled into the air cavity 301 along the regulating air tube 51 based on the suction force generated by nasal inhalation, thereby diluting the mist in the air cavity 301. As the use time increases, the drug atomizer in the ceramic atomizing tube 41 decreases, and the concentration of the mist generated by atomization decreases accordingly. At this time, by closing the airflow regulating hole 511, the airflow inhaled along the regulating air tube 51 is reduced, that is, the amount of air used to dilute the mist is reduced, so that the concentration of the diluted mist is at a certain concentration level.

[0064] To achieve the goal of inhaling the mist containing the drug into the nose, refer to Figures 1 to 5 、 Figures 9 and 10In some embodiments, the nasal nozzle assembly 200 further includes a nozzle base 22, a nozzle sealing insert 23, a nasal nozzle 24 and a nozzle cover 25. A mounting groove 252 is provided in the inner frame 251 of the nozzle cover 25. The nasal nozzle 24 is disposed in the mounting groove 252 and is fixed by the nozzle sealing insert 23 embedded in the inner frame 251. The nasal suction portion 241 of the nasal nozzle 24 passes through the nozzle cover 25 upward and extends out. The nozzle sealing insert 23 is provided with a through hole 231 that is docked with the mist suction channel 242 of the nasal nozzle 24 and passes through the nozzle sealing insert 23. An air guide hole 221 docked with the through hole 231 is provided at a position of the nozzle base 22 directly opposite the through hole 231. The guide body 21 is connected to the air guide hole 221. The guide body 21, the air guide hole 221, the through hole 231 and the mist suction channel 242 are also docked to form a mist suction channel for inhaling the mist in the air cavity 301.

[0065] In order to realize the switching of the atomizing unit composed of a ceramic atomizing assembly 400 and a corresponding airflow regulating assembly 500, and select the atomizing unit to work according to the demand, refer to Figures 1 to 5 In some embodiments, the nozzle sealing insert 23 is further recessed with a slide groove 232, in which an air regulating plate 26 capable of sliding along the transverse direction of the nozzle sealing insert 23 is provided. The through hole 231 is also connected to the slide groove 232 so that the mist suction channel passes through the slide groove 232, wherein the air regulating plate 26 is used to block or partially block the through hole 231 when sliding to a preset position in the slide groove 232, so as to control the amount of mist inhaled through the nose along the mist suction channel.

[0066] It should be noted that, in this embodiment, there are two atomizing units consisting of a ceramic atomizing assembly 400 and an airflow regulating assembly 500. The two atomizing units can be switched to work. At the same time, the air cavity 301 corresponding to each atomizing unit is connected to the chute 232 through a channel consisting of a guide body 21, an air guide hole 221 and a through hole 231, and the air regulating plate 26 placed in the chute 232 blocks the through hole 231 located below it, so that the corresponding channel is connected to the mist suction channel 242, thereby forming a flow path with the corresponding air cavity 301. The selected atomization unit corresponds to the atomization channel; in this embodiment, the nozzle sealing insert 23 is provided with through holes 231 arranged symmetrically in the transverse direction. When the air-regulating plate 26 slides transversely to the transverse left side of the nozzle sealing insert 23, the through holes 231 on the left side are blocked, indicating that the atomization unit on the right side is currently selected to work. Similarly, when the air-regulating plate 26 slides transversely to the transverse right side of the nozzle sealing insert 23, the through holes 231 on the right side are blocked, indicating that the atomization unit on the left side is currently selected to work (refer to Figure 5 ), it can be understood that when the air regulating plate 26 is in the middle position (refer to Figure 4), the air-regulating plate 26 partially blocks the two through-holes 231 on the left and right sides. At the same time, at this time, the two through-holes 231 are not completely blocked, and the two atomizing units are in working state. At this time, the mist generated by the atomization work of the two atomizing units is injected into the slide groove 232, and then flows into the mist suction channel 242 along the gap between the air-regulating plate 26 and the slide groove 232 on both sides, thereby ensuring the mist required for nasal atomization therapy; in this embodiment, the nasal suction nozzle assembly 200 is docked with the two atomizing units, and the mist generated by the two atomizing units can be transmitted to the user's nose through the nasal suction nozzle assembly 200, thereby realizing nasal atomization therapy; by setting two groups of atomizing units and performing air-regulating switching work through the air-regulating plate 26, the use effect of the nasal atomizing device is ensured, and the use time of the nasal atomizing device is extended.
