Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a salt spray generator and a dry salt aerosol generating device that facilitates liquid addition. Background Technology

[0002] Rock salt aerosol therapy (salt aerosol therapy) is a salt therapy method that generates salt aerosols with a particle size of less than 5 micrometers and inhales them into the lungs. It directly acts on the respiratory system to treat respiratory diseases by increasing the concentration of ions in the respiratory tract, changing the osmotic pressure of mucus, improving the rheology of respiratory mucus, activating the innate immunity of lung tissue, and enhancing the activity of lung macrophages. This achieves the goals of antibacterial and anti-inflammatory effects, relieving edema, enhancing clearance, expectoration, and boosting immunity and resistance, thereby preventing, improving, and treating respiratory diseases.

[0003] Currently, there are two types of rock salt aerosol generation equipment on the market. One type directly grinds salt ore into powder and blows it out to form salt aerosol. The other type generates rock salt aerosol based on salt solution. The device for generating rock salt aerosol based on salt solution includes a salt mist generator, an evaporation device, and a ventilation device. The salt mist generator atomizes the salt solution into tiny droplets of salt mist through atomizing plates. The evaporation device evaporates and dries the water in the salt mist to form salt particles. The ventilation device blows fresh air into the evaporation device, which accelerates the evaporation of the salt mist and blows out the dried salt particles to form salt aerosol. The salt aerosol particles formed by this method have small and uniform particle size, which allows them to enter the bronchioles and alveoli of the human lungs for treatment, directly reaching the lesion site and achieving better therapeutic effects.

[0004] In salt sol generation devices based on salt solutions, after the salt solution stored in the atomizing cup is consumed, it needs to be replenished to continue generating salt sol. Currently, the replenishment structure for salt spray generators is relatively complex and not conducive to miniaturization design. Summary of the Invention

[0005] To address the problems of complex liquid filling structures and inconvenient liquid filling in salt spray generators, this invention provides a salt spray generator that is easy to fill with liquid, with a simple structure, convenient operation, and the ability to quickly replenish liquid.

[0006] To achieve the above objectives, the specific solution of this utility model is as follows: a salt spray generator that is easy to add liquid, comprising an atomizing cup, an atomizing plate, and a liquid adding component. The atomizing cup includes an atomizing cup body and an atomizing cup cover. The atomizing cup cover can be closed on the atomizing cup body. The atomizing cup cover has a liquid adding port. The liquid adding component is disposed at the liquid adding port and is fixedly connected to the atomizing cup cover.

[0007] The upper part of the atomizing cup body is provided with a liquid storage chamber, and the liquid adding component is connected to the liquid storage chamber through the liquid adding port;

[0008] The liquid storage chamber has an atomizing port on one side of its bottom, and the atomizing plate is installed at the atomizing port.

[0009] Furthermore, the liquid addition component is integrally formed with the atomizing cup cover.

[0010] Furthermore, the liquid filling assembly includes a baffle and a puncture member. The baffle is disposed on the upper side of the atomizing cup cover and forms a liquid filling chamber with the atomizing cup cover. The liquid filling port is located inside the liquid filling chamber. The puncture member is disposed inside the liquid filling chamber and located above the liquid filling port. The liquid storage chamber is connected to the liquid filling chamber through the liquid filling port.

[0011] Furthermore, the puncture device includes a central puncture column, a puncture plate, and a puncture side plate, wherein the central puncture column is positioned directly above the liquid inlet;

[0012] The puncture plate and the puncture side plate are evenly arranged around the central puncture column, with one end connected to the central puncture column and the other end connected to the top cover of the atomizing cup.

[0013] Furthermore, the top of the central puncture column is provided with a first conical protrusion, and the edge of the puncture plate is provided with a second conical protrusion.

[0014] Furthermore, the liquid storage chamber includes a bottom wall, which is inclined from the edge toward the atomizing port, and the atomizing port is located on the side wall of the atomizing cup body corresponding to the lowest point of the liquid storage chamber.

[0015] Furthermore, the liquid storage chamber is provided with an atomizing chamber sidewall, which separates the liquid storage chamber from the atomizing chamber. A flow guide groove is provided on the atomizing chamber sidewall, and the atomizing chamber is connected to the liquid storage chamber through the flow guide groove. The atomizing port is opened on one side of the atomizing chamber, and the atomizing plate is connected to the atomizing chamber through the atomizing port.

[0016] Furthermore, it also includes a reservoir bottle adapted to the puncture device, the reservoir bottle including a bottle body, a bottle neck and a bottle mouth, the connection between the bottle body and the bottle neck forming a stepped surface, the bottle mouth being sealed by a sealing film, the diameter of the bottle neck being smaller than the inner diameter of the retaining member, and the diameter of the bottle body being larger than the inner diameter of the retaining member.

[0017] Furthermore, when the storage bottle is inverted on the liquid filling assembly, the bottleneck is placed inside the liquid filling chamber, the stepped surface abuts against the upper edge of the enclosure, and the piercing member pierces the sealing film at the bottle opening and extends into the interior of the storage bottle.

[0018] A dry salt aerosol generating device, including the aforementioned salt spray generator, was also disclosed.

[0019] The beneficial effects of this utility model are:

[0020] 1. By setting a liquid addition component and a matching liquid storage bottle on the top cover of the atomizing cup, the liquid addition component can pierce the sealing membrane of the liquid bottle opening and introduce the salt solution into the storage chamber simply by inverting the liquid storage bottle on the liquid addition component. The structure is simple and the operation is convenient. Moreover, the salt solution in the liquid storage bottle can be completely added into the storage chamber without any solution residue, thus avoiding waste.

[0021] 2. An atomizing chamber is set in the liquid storage chamber, and the atomizing chamber and the liquid storage chamber are separated by the side wall of the atomizing chamber. The salt solution in the liquid storage chamber can only flow slowly into the atomizing chamber through the guide groove on the side wall of the atomizing chamber, which avoids the impact on the atomizing plate when replenishing the liquid. This can stabilize the atomization rate of the atomizing plate and extend the working life of the atomizing plate. Attached Figure Description

[0031] Reference Figures 1 to 3 As shown, an embodiment of a salt spray generator that is easy to add liquid includes an atomizing cup 1, an atomizing plate 15, and a liquid adding component 3. The atomizing cup 1 includes an atomizing cup body 12 and an atomizing cup cover 11. The atomizing cup cover 11 can cover the atomizing cup body 12. The atomizing cup cover 11 has a liquid adding port 111. The liquid adding component 3 is disposed at the liquid adding port 111 and is fixedly connected to the atomizing cup cover 11.

[0032] The upper part of the atomizing cup body 12 is provided with a liquid storage chamber 13, and the liquid adding component 3 is connected to the liquid storage chamber 13 through the liquid adding port 111;

[0033] Atomizing port 143 is provided on one side of the bottom of the liquid storage chamber 13, and atomizing plate 15 is installed at atomizing port 143.

[0034] The liquid filling component 3 and the atomizing cup cover 11 can be integrally formed, or an installation groove can be opened on the atomizing cup cover to install the liquid filling component in the installation groove and seal it, as long as it is ensured that there is no water leakage between the liquid filling component and the atomizing cup cover.

[0035] In this embodiment, the liquid addition component 3 and the atomizing cup cover 11 are directly machined in one piece.

[0036] like Figure 1 and Figure 2 As shown, the liquid filling assembly 3 includes a baffle 31 and a puncture member 33. The baffle 31 is disposed on the upper side of the atomizing cup cover 11 and forms a liquid filling chamber 32 with the atomizing cup cover 11. The liquid filling port 111 is located inside the liquid filling chamber 32. The puncture member 33 is disposed inside the liquid filling chamber 32 and located above the liquid filling port 111. The liquid filling chamber 32 is connected to the liquid storage chamber 13 through the liquid filling port 111.

[0037] like Figure 2 As shown, the puncture component 33 includes a central puncture column 331, a puncture plate 332, and a puncture side plate 333. The central puncture column 331 is located directly above the liquid inlet 111.

[0038] The puncture plate 332 and the puncture side plate 333 are evenly arranged around the central puncture column 331 and connected to the top cover 11 of the atomizing cup.

[0039] In this embodiment, there are two puncture plates 332 and two puncture side plates 333, which are arranged in a cross manner. The two puncture plates 332 are symmetrically arranged on both sides of the central puncture column 331, and the puncture side plates 333 are arranged perpendicular to the puncture plates 332.

[0040] like Figure 3 As shown, the liquid storage chamber 13 includes a bottom wall 131, which is inclined from the edge toward the atomizing port 143. The atomizing port 143 is located on the side wall of the atomizing cup body 12 corresponding to the lowest point of the liquid storage chamber 13.

[0041] In a further embodiment, the liquid storage chamber 13 is provided with an atomizing chamber sidewall 141, which separates the liquid storage chamber 13 into an atomizing chamber 14. A guide groove 142 is provided on the atomizing chamber sidewall 141, and the atomizing chamber 14 is connected to the liquid storage chamber 13 through the guide groove 142. An atomizing port 143 is provided on one side of the atomizing chamber 14, and the atomizing plate 15 is connected to the atomizing chamber 14 through the atomizing port 143.

[0042] In a further embodiment, refer to Figure 3 As shown, the atomizing chamber sidewall 141 penetrates the bottom wall 131 of the liquid storage chamber and extends to a position below the bottom wall 131 of the liquid storage chamber. The lowest point of the atomizing chamber 14 formed by the sidewall of the atomizing cup body 12 is lower than the lowest point of the liquid storage chamber. A liquid level sensor (not shown in the figure) is installed on the outer wall of the atomizing chamber sidewall 141 to detect the liquid level information in the atomizing chamber 14 in real time.

[0043] like Figure 4 As shown, an embodiment of a liquid storage bottle 2 adapted to the puncture member 33 is provided. The liquid storage bottle 2 includes a bottle body 21, a neck 22, and a bottle mouth 24. A stepped surface 23 is formed at the connection between the bottle body 21 and the neck 22. The bottle mouth 24 is sealed by a sealing film. The diameter of the neck 22 is smaller than the inner diameter of the retaining member 31, and the diameter of the bottle body 21 is larger than the inner diameter of the retaining member 31.

[0044] When the storage bottle 2 is inverted on the liquid filling assembly 3, the neck 22 is placed inside the liquid filling chamber 32, the stepped surface 23 abuts against the upper edge of the enclosure 31, and the piercing member 33 penetrates the sealing film of the bottle mouth 24 and extends into the interior of the storage bottle 2, guiding the salt solution in the storage bottle 2 into the storage chamber through the liquid filling port 111.

[0045] like Figure 5As shown, in a further embodiment, the top of the central puncture post 331 is provided with a first conical protrusion 3311, and the edge of the puncture plate 332 is provided with a second conical protrusion 3321.

[0046] The conical protrusions on the central puncture column 331 and puncture plate allow for faster and more convenient puncture of the sealing membrane of the liquid storage bottle 2.

[0047] In a further embodiment, a second guide groove (not shown in the figure) and / or guide hole (not shown in the figure) are provided on the central puncture column 331, which can better guide the saline solution in the storage bottle 2 to the storage chamber 13, and prevent the punctured sealing film from sticking to the puncture piece 33, causing the saline solution to be unable to flow out normally.

[0048] When the puncture device 33 punctures the sealing membrane of the storage bottle 2 to form an outlet, the sealing membrane may adhere to the central puncture column 331, puncture plate 332, and puncture side plate 333, blocking the outlet. The saline solution in the storage bottle 2 cannot flow smoothly into the storage chamber 13 through the outlet. A second guide groove or guide hole is provided on the central puncture column 331 to guide the saline solution in the storage bottle 2 into the storage chamber 13, thus completing the addition of the solution.

[0049] It is known that the second guide channel and / or guide hole can also be set on the puncture plate 332 and / or puncture side plate 333, which can also serve the purpose of guiding the salt solution in the storage bottle 2 to the storage chamber 13.

[0050] An embodiment of a dry salt aerosol generating device includes a salt spray generator that facilitates liquid addition as described in this embodiment. With the salt spray generator in this embodiment, when the salt aerosol generating device needs to be replenished with liquid, the liquid replenishment operation can be completed quickly, saving liquid replenishment time. Moreover, the newly replenished salt solution is slowly introduced into the atomization chamber, stabilizing the operation of the atomization plate and improving the stability of the salt aerosol concentration and particle size.

[0051] In actual use, the specific operation is as follows: when the liquid level sensor detects that the liquid level in the atomizing chamber 14 is lower than the minimum threshold, a low liquid level alarm signal is issued. The empty storage bottle 2 on the liquid addition assembly 3 is manually removed, and a new storage bottle 2 filled with saline solution is placed upside down on the liquid addition assembly 3. The puncture device 33 punctures the sealing film of the storage bottle 2, and the saline solution in the storage bottle 2 is introduced into the storage chamber 13 through the liquid addition port 111. Then, it flows into the atomizing chamber through the guide channel 142 to complete the liquid addition of the saline mist generator. Then, the atomizing plate starts to work to atomize the saline solution in the atomizing chamber into tiny droplets of saline mist. Then, the evaporation module evaporates the water in the saline mist to form dry saline particles. The ventilation module inputs fresh air to blow out the dry saline particles to form saline aerosol for the user to inhale for treatment.

[0052] In this invention, the salt refers to sodium chloride; the salt solution refers to the sodium chloride solution formed by dissolving sodium chloride in water, which may contain trace amounts of elements such as magnesium and potassium; the salt mist refers to the salt mist formed by atomizing the salt solution into tiny droplets by an atomizing plate; and the dry salt aerosol, salt sol, and rock salt aerosol are all solid aerosols formed by dry salt particles suspended in the air.

[0053] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not limiting. Those skilled in the art can make many specific modifications under the guidance of the present invention without departing from the spirit of the invention and the scope of protection of the claims, and these modifications all fall within the protection scope of the present invention.
