Description

Atomizer

The invention relates to an atomizer. In particular, it relates to a disposable atomizer including a multi-stage adjustable mist size and air pressure adjustment device.

Nebulized inhalation therapy is a popular medical treatment for respiratory diseases in recent years. Nebulized inhalation therapy is mainly through nebulizers, such as nebulizers, to disperse drugs (such as solutions or powders) into tiny droplets or particles suspended in the gas, allowing users to inhale the drug droplets or particles into the respiratory tract and In the lungs, so that the drug drops or drug particles can be fully absorbed by the human body to achieve clean airway and treatment effects. Therefore, the size and quality of the droplets will also directly affect the treatment effect.

The current nebulizer products used for medical purposes can be roughly divided into electronic ultrasonic nebulizers and hand-held suction bulb nebulizers. However, the electronic ultrasonic atomizer and the hand-held bulb atomizer have the following disadvantages. The electronic ultrasonic nebulizer needs electricity, and the battery needs to be charged or replaced when the battery is exhausted. Otherwise, the nebulization inhalation treatment cannot be carried out, and the nebulizer needs to be cleaned after each nebulization treatment. Incompleteness can easily lead to residual drug crystals and block the vent holes, making the next atomization effect poor. In addition, the mesh stainless steel sheet used in the electronic ultrasonic atomizer may be oxidized, rusted and cracked, exposing the user to the risk of inhaling the stainless steel sheet.

Since the hand-held suction ball has no power supply, the user needs to keep pressing the suction ball with his hand to suck air and activate the atomizer. Therefore, the handheld suction ball is not suitable for long-term use.

The atomizer 100 includes an air supply pipe 110, an air pressure adjusting device 120 and a high-pressure gas cylinder 130. The high-pressure gas cylinder 130 contains high-pressure gas to provide gas power for generating mist. The air pressure adjusting device 120 is installed in the air supply pipe 110 and the high Between the pressure cylinders 130, the air pressure sprayed from the high-pressure cylinder 130 is adjusted to adjust the size of the mist generated in the air supply pipe 110. The air supply pipe 110 has a fluid inlet 111a and an air outlet 113a. The fluid inlet 111a is located above the air supply pipe 110 (that is, the end of the air supply pipe 110 away from the air pressure regulating device 120). The air outlet 113a is located on the side of the air supply pipe 110. The liquid medicine can be filled and stored in the air supply tube 110 through the fluid inlet 111a. The high-pressure gas in the high-pressure gas cylinder 130 passes through the air pressure adjusting device 120 to the air supply pipe 110, so that the liquid medicine in the air supply pipe 110 is dispersed into tiny droplets suspended in the gas to form a mist to fill the air supply pipe 110. The user can bring the mouth and nose close to the air outlet 113a to absorb the mist in the air supply tube 110 to achieve the effect of drug absorption and treatment. (The formation of mist will be described in more detail in Figure 3 below).

In some embodiments, the high-pressure gas cylinder 130 is a disposable high-pressure bottle, but the invention should not be limited to this.

Please refer to Figure 2. Figure 2 is a cross-sectional view of the air pressure regulating device 120 in Figure 1 along the line 2-2. As shown in FIG. 2, the air pressure adjusting device 120 includes a base 121, an adjusting shaft 122, a throttle element 123, a biasing element 124, a support 125 and a boss 126. The base 121 includes a first sleeve 1211, a second sleeve 1212, a first channel 1213, and a second channel 1214. The first channel 1213 is provided in the first sleeve 1211, the second channel 1214 is provided in the second sleeve 1212, and the first channel 1213 is substantially connected to the second channel 1214. The first sleeve 1211 includes a first connecting portion 1211a, a second connecting portion 1211b, and an opening 1211c. The first connecting portion 1211 a and the second connecting portion 1211 b are both provided on the inner wall of the first sleeve 1211. The first connecting portion 1211 a is disposed outside the first channel 1213 and away from one end of the second channel 1214. The second connecting portion 1211b is arranged in the first channel Outside of 1213, one end away from the first connecting portion 1211a. The opening 1211c is opened at an end of the first sleeve 1211 away from the first passage 1213 and the first connecting portion 1211a. The second sleeve 1212 is disposed in the first sleeve 1211. The second sleeve 1212 includes a butting portion 1212b. The docking portion 1212b is provided on the outer wall of the second sleeve 1212 at a position corresponding to the second connecting portion 1211b of the first sleeve 1211. The second sleeve 1212 is engaged with the first sleeve 1211 through the second connecting portion 1211b and the mating portion 1212b, and is exposed through the opening 1211c of the first sleeve 1211.

In some embodiments, the second engaging portion 1211b is a protruding structure. Correspondingly, the mating portion 1212b is a groove structure. The second connecting portion 1211 b of the first sleeve 1211 fits in the mating portion 1212 b of the second sleeve 1212 so that the second sleeve 1212 is fixed in the first sleeve 1211. In other embodiments, the second connecting portion 1211b is a groove structure, and the mating portion 1212b is a protrusion structure. The mating portion 1212b fits into the second engaging portion 1211b to fix the second sleeve 1212 in the first sleeve 1211, but the invention should not be limited to this.

Further, the second sleeve 1212 further includes an internal thread 1212a. The internal thread 1212 a is disposed on the inner wall of the second sleeve 1212 and configured to be screwed with the high-pressure gas cylinder 130.

In some embodiments, the first sleeve 1211 and the second sleeve 1212 are integrally formed. Therefore, in this embodiment, the first sleeve 1211 does not need to include the second engagement portion 1211b, and the second sleeve 1212 does not need to include the butting portion 1212b, but the invention should not be limited to this.

Please continue to refer to Figure 2. The boss 126 is disposed in the second sleeve 1212, adjacent to the first channel 1213, and extends in a direction away from the first channel 1213 stretch. The second channel 1214 penetrates the boss 126. The boss 126 is configured to penetrate into the high-pressure gas cylinder 130 when the second sleeve 1212 is screwed with the high-pressure gas cylinder 130, so that the high-pressure gas in the high-pressure gas cylinder 130 escapes along the second passage 1214. In this embodiment, the boss 126 and the second sleeve 1212 are integrally formed. In some embodiments, the boss 126 and the second sleeve 1212 are two separate components. The invention should not be limited to this.

The adjusting shaft 122 partially penetrates into the first channel 1213 from an end of the first channel 1213 away from the second channel 1214, and is connected with the base 121 by the first connecting portion 1211 a of the first sleeve 1211. The adjusting shaft 122 is configured to rotate relative to the base 121 to enter and exit the first passage 1213. Specifically, the first connecting portion 1211a is an internal thread. Correspondingly, the outer wall of the adjusting shaft 122 includes an external thread 122a. The internal thread of the first connecting portion 1211 a is threadedly engaged with the external thread 122 a of the adjusting shaft 122 so that the adjusting shaft 122 can rotate relative to the base 121 to enter and exit the first channel 1213. The adjustment shaft 122 further includes an air inlet 1221, an air outlet 1222, and a third passage 1223. The air inlet 1221 is located at an end of the adjusting shaft 122 extending into the first passage 1213, and the air inlet 1221 is located on the outer wall of the adjusting shaft 122. In some embodiments, the air inlet 1221 may also be provided at a port of one end of the adjusting shaft 122 extending into the first passage 1213, and the present invention is not limited thereto. The air outlet 1222 is located at the port of the end of the adjusting shaft 122 protruding out of the first channel 1213. A hollow channel is formed between the air inlet 1221 and the air outlet 1222 to penetrate the adjusting shaft 122, and the hollow channel is the third channel 1223. Thereby, the third passage 1223 of the adjusting shaft 122 and the first passage 1213 of the base 121 are communicated via the air inlet 1221.

Please continue to refer to Figure 2. As shown in Figure 2, in this embodiment, the throttle element 123 is a sphere, but the invention should not be limited to this. Throttling element The member 123 is disposed in the first passage 1213 in the base 121, and abuts against one end 1214a of the second passage 1214 close to the first passage 1213 (that is, the air outlet of the second passage 1214) to limit the high pressure in the high-pressure gas cylinder 130 The amount of gas emitted. In this embodiment, the width of the end 1214a is tapered from the end close to the first channel 1213 toward the second channel 1214 to form an inclined surface structure. In this way, the spherical throttling element 123 can stably and effectively abut against the air outlet of the second channel 1214 to prevent the high pressure gas in the high pressure gas cylinder 130 from leaking when the atomizer 100 is closed. However, the present invention should not be limited to this.

The biasing element 124 is disposed in the first passage 1213 and abuts between the throttling element 123 and an end of the first passage 1213 close to the first connecting portion 1211a. The biasing element 124 is configured to provide an adjusting force applied to the throttle element 123, and the adjusting force is determined according to the high pressure gas pressure and the displacement of the throttle element 123 adjusted by the adjusting shaft 122 to control the high pressure gas from the second passage 1214 flows through the first channel 1213 through the air flow dynamic mechanism. For example, the biasing element 124 is a coil spring. The biasing element 124 is sleeved outside the end of the adjusting shaft 122 with the air inlet 1221. When the adjustment shaft 122 rotates relative to the base 121 and penetrates into the first passage 1213, the adjustment shaft 122 exerts force on the throttling element 123 to bias it toward the second passage 1214 to restrict the flow of high-pressure gas through the second passage 1214, The equivalent flow area of the first channel 1213 reduces the flow of high-pressure gas. In other words, if the force of the throttling element 123 by the biasing element 124 is less than the pressure of the throttling element 123 being ejected by the high-pressure gas, and the throttling element 123 is not restricted by the adjustment shaft 122, the high-pressure gas can be biased according to the pre-design. The elastic force of the set element 124 and the high-pressure gas pressure provide a pre-designed maximum flow rate to reach the air supply pipe 110 via the second channel 1214, the first channel 1213 and the third channel 1223.

The support 125 of the air pressure adjusting device 120 is a hollow sleeve, and is sleeved on the part of the adjusting shaft 122 located outside the base 121. The support 125 includes an engaging portion 1251 and an internal thread 1252. The engaging portion 1251 is provided on the inner wall of the support 125 and protrudes relative to the inner wall of the support 125. The support 125 is engaged with the adjustment shaft 122 by the engaging portion 1251. Specifically, the adjustment shaft 122 further includes a slot portion 1224 and an inclined surface 1225. The slot portion 1224 and the inclined surface 1225 are both provided on the outer wall of the adjusting shaft 122 and exposed by the base 121. The slot portion 1224 is provided on the outer wall of the adjusting shaft 122 close to the base 121. The inclined surface 1225 is adjacent to an end of the slot portion 1224 away from the base 121. The height of the inclined surface 1225 relative to the outer wall of the adjusting shaft 122 increases toward the slot portion 1224. Thereby, when assembling the support 125 and the adjustment shaft 122, the assembler applies a force to press the engaging portion 1251 of the support 125 along the inclined surface 1225 of the adjustment shaft 122 and approach the base 121. The engaging portion 1251 of the support 125 passes through the inclined surface 1225 and then engages with the engaging groove portion 1224 of the adjusting shaft 122. The end of the inclined surface 1225 adjacent to the groove portion 1224 can restrict the movement of the engaging portion 1251 along the extending direction of the adjusting shaft 122 to prevent the support 125 from separating from the adjusting shaft 122 along the outer wall of the adjusting shaft 122. The internal thread 1252 of the support 125 is disposed on the inner wall of the support 125 away from the base 121. The internal thread 1252 is configured to be screwed with the air supply pipe 110.

Please refer to Figure 3. Figure 3 is a partial cross-sectional view of the atomizer 100 in Figure 1 along the line 3-3. Hereinafter, the structure and operation mode of the atomizer 100 of this embodiment will be described in conjunction with the air pressure adjusting device 120 shown in FIG. 2.

As shown in FIG. 3, the air supply tube 110 includes a main body 112, a sleeve portion 114, a wing 116, a fourth channel 118, a fifth channel 111 and an air supply channel 113. The main body 112 is a hollow cylinder with a containing area 112a inside. Containment area 112a configuration To store potions. The sleeve portion 114 is disposed at the bottom of the main body 112 (that is, one end of the main body 112 close to the air pressure regulating device 120 ), and extends toward the accommodating area 112 a and the air pressure regulating device 120. In this embodiment, the socket portion 114 and the body portion 112 are integrally connected, but the invention should not be limited to this. The wing portion 116 is connected to the outer wall of the sleeve portion 114 and protrudes relative to the outer wall of the sleeve portion 114. The wing 116 is configured to be screwed with the internal thread 1252 of the support 125 (as shown in FIG. 2 ), so that the sleeve 114 is engaged between the support 125 and the adjustment shaft 122 of the air pressure adjusting device 120. Thereby, the air supply pipe 110 and the air pressure adjusting device 120 are fixed.

In this embodiment, the wing portion 116 is integrally connected with the outer wall of the sleeve portion 114, but the invention should not be limited to this.

The fourth channel 118 is located in the socket 114 and communicates with the accommodating area 112a. The adjusting shaft 122 partially penetrates into the fourth passage 118 so that the third passage 1223 of the adjusting shaft 122 is communicated with the fourth passage 118 of the air supply pipe 110. The width W1 of the fourth channel 118 (that is, the width between the inner walls of the socket 114) gradually increases toward the adjustment shaft 122. In contrast, the width W2 of the outer wall of the adjustment shaft 122 decreases toward the fourth passage 118. Therefore, when the wing 116 is screwed with the internal thread 1252 of the support 125, the outer wall of the adjusting shaft 122 can be matched with the inner wall of the socket 114 to form an airtight structure. This prevents gas from leaking from the joint between the sleeve portion 114 and the adjusting shaft 122 when the gas flows through the third channel 1223 and the fourth channel 118.

The fourth passage 118 has an air outlet 118 a located at an end of the fourth passage 118 that extends into the main body 112. The width of the air outlet 118a (not marked in the figure is omitted because the width is too small) is smaller than any width W1 of the fourth channel 118. For example, the width of the air outlet 118a is about 0.5~1.5mm, and the width of the fourth channel 118 The width W1 is about 4-6 mm, but the invention should not be limited to this.

The fifth channel 111 extends in the main body 112 and communicates with the fourth channel 118 and the accommodating area 112a. The fifth channel 111 has a fluid inlet 111a, a fluid outlet 111b, and a rod 111c. The fluid inlet 111a is located at an end of the fifth channel 111 away from the fourth channel 118. Conversely, the fluid outlet 111b is located at an end of the fifth channel 111 close to the fourth channel 118. The rod portion 111c straddles the fluid outlet 111b and is aligned with the air outlet 118a of the fourth passage 118. Thereby, the liquid medicine can be inserted from the fluid inlet 111a, and after passing through the fifth channel 111, it flows from the fluid outlet 111b to the containing area 112a of the main body 112 for storage. The rod portion 111c crosses the fluid outlet 111b to prevent the medicine from blocking the air outlet 118a of the fourth channel 118.

The air supply channel 113 is connected to the outer wall of the main body 112 and extends outward from the main body 112 relative to the outer wall of the main body 112. The air supply channel 113 communicates with the accommodating area 112 a in the main body 112. The user can move the mouth and nose close to the air outlet 113a at one end of the air duct 113 away from the main body 112 to absorb the medicine mist or droplets in the main body 112.

The high-pressure gas cylinder 130 has a mouth 132. The bottle mouth 132 is engaged with the end of the base 121 of the air pressure adjusting device 120 away from the adjusting shaft 122. Specifically, the outer wall of the bottle mouth 132 has an external thread 1321. The external thread 1321 of the bottle mouth 132 is screwed with the internal thread 1212a of the second sleeve 1212 of the air pressure regulator 120. Thereby, the high-pressure gas cylinder 130 and the air pressure adjusting device 120 are fixed together. A film 1322 is adhered to the bottle mouth 132. The membrane 1322 is configured to seal the high-pressure gas in the high-pressure gas cylinder 130. When the high-pressure gas cylinder 130 is screwed to the base 121 of the air pressure adjusting device 120 and approaching the air pressure adjusting device 120, the protrusion 126 of the air pressure adjusting device 120 pierces the film 1322 on the bottle mouth 132 and penetrates the bottle mouth 132.

In some embodiments, the manner in which the high-pressure gas cylinder 130 and the air pressure adjusting device 120 are fixed to each other is not limited to the method of screwing. In other words, in some embodiments, the high-pressure gas cylinder 130 and the air pressure adjusting device 120 are fixed to each other by the engagement between the protrusion and the groove, and the present invention should not be limited to this.

It can be seen from the above structural configuration that in the atomizer 100 of one embodiment of the present invention, when the protrusion 126 penetrates into the mouth 132 of the high-pressure gas cylinder 130, the high-pressure gas in the high-pressure gas cylinder 130 will follow the first The two channels 1214 flow to the air pressure adjusting device 120. The pressure of the high-pressure gas pushes the throttling element 123 toward the adjustment shaft 122 and the biasing element 124 to allow the high-pressure gas to flow into the first channel 1213. Further, the high-pressure gas flows in from the air inlet 1221 of the adjusting shaft 122, sequentially passes through the third passage 1223 and the fourth passage 118, and finally flows out from the air outlet 118a. According to Bernoulli's principle, after high-pressure gas is ejected through the small outlet 118a, negative pressure will be generated at the outlet 118a. The negative pressure sucks up the medicine in the accommodating area 112a, so that the medicine is torn into small water droplets by the high-speed flowing high-pressure gas, forming mist (droplets) filled in the air supply pipe 110.

By adjusting the rotation of the adjusting shaft 122 relative to the first passage 1213, the combined force of the high pressure gas received by the throttling element 123 and the bias element 124 can be adjusted to control the pressure and flow rate of the high pressure gas ejection, thereby achieving a multi-stage type The purpose of adjusting the size of the mist.

Please refer to Figure 4. Fig. 4 is a perspective view of an atomizer 200 according to another embodiment of the present invention. As shown in Fig. 4, the atomizer 200 includes an air supply pipe 210, a gas pressure regulating device 120, and a high-pressure gas cylinder 130. The gas pressure regulating device 120 and the high-pressure gas cylinder 130 are the same as the embodiments shown in Figs. 1 to 3, so Please refer to the aforementioned related descriptions, which will not be repeated here. It’s important to note that this implementer The difference between the formula and the embodiment shown in FIGS. 1 to 3 is that the air supply pipe 210 of this embodiment is bent relative to the air pressure adjusting device 120 and the high-pressure gas cylinder 130. Specifically, the sleeve portion 214 of the air supply pipe 210 has a bent section 214a. The bending section 214a is bent relative to the air pressure adjusting device 120 and the high-pressure gas cylinder 130, for example, about 88 to 92 degrees, but the present invention should not be limited to this. Therefore, the air supply pipe 210 is bent and offset relative to the air pressure adjusting device 120 and the high-pressure gas cylinder 130.

From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that the atomizer of the present invention uses the adjustment shaft of the air pressure adjusting device to rotate in and out of the base to control the throttling element. The combined force from the high-pressure gas cylinder and the biasing element achieves the effect of multi-stage adjustment of the mist pressure. In addition, different from the existing portable nebulizer, each time it is used, it will cause the drug crystals to remain uncleaned, making the subsequent use of the nebulization effect poor. The nebulizer of the present invention can be used as a disposable nebulizer by simplifying the air pressure adjustment structure. The carburetor can be discarded after a single use, so there will be no problems of drug crystal residues, durability problems after repeated use, and poor atomization effects.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone who is familiar with the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection of the present invention The scope shall be subject to the scope of the attached patent application.
