Description

Atomizer

Technical Field

The present invention relates to an atomizer, and more particularly, to a disposable atomizer including an air pressure adjusting device for adjusting the amount of mist.

Background

Aerosol inhalation therapy is a medical treatment that has become prevalent in recent years for the treatment of respiratory diseases. The aerosol inhalation therapy is mainly to disperse the medicine (such as solution or powder) into tiny droplets or particles suspended in the air by an atomization device, such as an atomizer, so that the user can inhale the droplets or particles into the respiratory tract and the lung, so that the droplets or particles can be fully absorbed by the human body, and the effects of cleaning the airway, treating and the like are achieved. Therefore, the size and quality of the droplets also directly affect the effectiveness of the treatment.

Currently, nebulizer products for medical use can be broadly classified into electronic ultrasonic nebulizers and hand-held suction-ball nebulizers. However, the electronic ultrasonic atomizer and the hand-held suction ball atomizer have the following disadvantages, respectively. Electronic type ultrasonic nebulizer needs the power consumption, and the battery exhausts and need charge or the battery is changed promptly, otherwise can't carry out the aerosol inhalation treatment, and need wash the atomizer after the aerosol treatment at every turn, nevertheless if wash incompletely, easily lead to the medicine crystallization to remain to block the venthole, make next time atomization effect not good. In addition, the mesh type stainless steel sheet used in the electronic ultrasonic atomizer has a possibility of oxidation rusting and cracking, exposing the user to the risk of inhaling the stainless steel sheet.

The hand-held suction ball is free of power supply, so that a user needs to continuously press the suction ball with hands to suck and send air to enable the atomizer to act. The hand-held suction ball is not suitable for long-term use.

Therefore, how to provide an atomizer capable of solving the above problems and adjusting the mist size is one of the problems to be solved in the art.

Detailed Description

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

Please refer to fig. 1. Fig. 1 shows a perspective view of a nebulizer 100 according to an embodiment of the invention. As shown in fig. 1, the nebulizer 100 of the present embodiment is a pneumatic nebulizer designed based on the bernoulli's law. The nebulizer 100 can be used to disperse a liquid (e.g., a liquid medicine) into tiny droplets and suspend the droplets in a gas, so that a user can inhale into the respiratory tract and the lung to achieve a therapeutic effect.

The nebulizer 100 includes an air feed 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 between the air supply pipe 110 and the high pressure gas cylinder 130 to adjust the air pressure sprayed from the high pressure gas cylinder 130, thereby adjusting the mist size generated in the air supply pipe 110. The air feed pipe 110 has a fluid inlet 111a and an air outlet 113 a. The fluid inlet 111a is located above the air supply pipe 110 (i.e., the end of the air supply pipe 110 away from the air pressure adjusting device 120). The air outlet 113a is located at a side of the air supply pipe 110. The liquid medicine can be filled in the air supply pipe 110 through the fluid inlet 111 a. The high-pressure gas in the high-pressure gas bottle 130 passes through the gas pressure adjusting device 120 to the gas supply pipe 110, so that the liquid medicine in the gas supply pipe 110 is dispersed into tiny droplets suspended in the gas, and the mist is filled in the gas supply pipe 110. The user can approach the mouth and nose to the air outlet 113a to absorb the mist in the air pipe 110, thereby achieving the effect of drug absorption and treatment. (the manner in which the mist is formed is described in more detail below in connection with FIG. 3.)

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

Please refer to fig. 2. Fig. 2 shows a cross-sectional view of the air pressure adjusting device 120 shown in fig. 1 along line a-a. As shown in fig. 2, the air pressure adjusting device 120 includes a base 121, an adjusting shaft 122, a throttling assembly 123, a biasing assembly 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 disposed within the first sleeve 1211, the second channel 1214 is disposed within the second sleeve 1212, and the first channel 1213 is substantially connected to the second channel 1214. The first sleeve 1211 includes a first engagement portion 1211a, a second engagement portion 1211b, and an opening 1211 c. The first and second engagement portions 1211a and 1211b are provided on an inner wall of the first sleeve 1211. The first engagement portion 1211a is disposed outside the first channel 1213 and away from one end of the second channel 1214. The second engagement portion 1211b is disposed outside the first channel 1213, away from an end of the first engagement portion 1211 a. The opening 1211c is opened at an end of the first sleeve 1211 remote from the first channel 1213 and the first engagement portion 1211 a. The second sleeve 1212 is disposed within the first sleeve 1211. The second sleeve 1212 includes a docking portion 1212 b. The abutting portion 1212b is provided on an outer wall of the second sleeve 1212 at a position corresponding to the second engagement portion 1211b of the first sleeve 1211. The second sleeve 1212 is engaged with the first sleeve 1211 through the second engaging portion 1211b and the abutting portion 1212b, and is exposed through the opening 1211c of the first sleeve 1211.

In some embodiments, the second engagement portion 1211b has a protrusion structure. Correspondingly, the docking portion 1212b has a groove structure. The second engagement portion 1211b of the first sleeve 1211 is fittingly engaged with the engagement portion 1212b of the second sleeve 1212, so that the second sleeve 1212 is fixed in the first sleeve 1211. In other embodiments, the second engagement portion 1211b has a groove structure, and the mating portion 1212b has a protrusion structure. The abutting portion 1212b is fittingly engaged with the second engaging portion 1211b to fix the second sleeve 1212 to the first sleeve 1211, but the invention is not limited thereto.

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

In some embodiments, the first sleeve 1211 is integrally formed with the second sleeve 1212. 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 engagement portion 1212b, but the invention should not be limited thereto.

Please continue to refer to fig. 2. The post 126 is disposed in the second sleeve 1212, adjacent to the first channel 1213, and extends away from the first channel 1213. Second channel 1214 extends through post 126. The post 126 is configured to penetrate into the high pressure gas cylinder 130 when the second sleeve 1212 is screwed into the high pressure gas cylinder 130, so that the high pressure gas in the high pressure gas cylinder 130 is discharged along the second channel 1214. In this embodiment, the post 126 is integrally formed with the second sleeve 1212. In some embodiments, the post 126 and the second sleeve 1212 are separate two pieces. The invention should not be limited thereto.

The adjusting shaft 122 partially penetrates the first channel 1213 from an end of the first channel 1213 away from the second channel 1214, and is engaged with the base 121 by the first engaging portion 1211a of the first sleeve 1211. The adjustment shaft 122 is configured to rotate relative to the base 121 into and out of the first channel 1213. Specifically, the first engagement portion 1211a is a female screw. Correspondingly, the outer wall of the adjustment shaft 122 comprises an external thread 122 a. The internal threads of the first engagement portion 1211a are matingly threaded with the external threads 122a of the adjustment shaft 122 such that the adjustment shaft 122 is rotatable relative to the base 121 into and out of 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 the end of the adjustment shaft 122 that protrudes into the first channel 1213, and the air inlet 1221 is located on the outer wall of the adjustment shaft 122. In some embodiments, the air inlet 1221 may also be disposed at a port at an end of the adjustment shaft 122 extending into the first channel 1213, but the invention is not limited thereto. The air outlet 1222 is ported at an end of the adjustment shaft 122 that extends out of the first channel 1213. A hollow passage, i.e., a third passage 1223, is formed between the air inlet 1221 and the air outlet 1222 and extends through the adjustment shaft 122. Thereby, the third passage 1223 of the adjustment shaft 122 communicates with the first passage 1213 of the base 121 via the air inlet 1221.

Please continue to refer to fig. 2. As shown in fig. 2, in the present embodiment, the throttling element 123 is a sphere, but the invention should not be limited thereto. The throttle assembly 123 is disposed in a first passage 1213 in the base 121 and abuts an end 1214a of the second passage 1214 close to the first passage 1213 (i.e., an air outlet of the second passage 1214) to limit the ejection amount of the high-pressure air in the high-pressure air cylinder 130. In this embodiment, the width of the end 1214a tapers from the end near the first channel 1213 toward the second channel 1214, forming a ramp structure. Thus, the spherical throttling element 123 can stably and effectively abut against the air outlet of the second channel 1214, so as 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 thereto.

The biasing member 124 is disposed in the first passage 1213 and abuts between the throttling member 123 and an end of the first passage 1213 near the first engagement portion 1211 a. The biasing assembly 124 is configured to provide a regulating force to the throttling assembly 123, and the regulating force is determined by the pressure of the high-pressure gas and the displacement of the throttling assembly 123 regulated by the regulating shaft 122, so as to control the gas flow power of the high-pressure gas flowing from the second passage 1214 through the first passage 1213. For example, the biasing member 124 is a coil spring. The biasing member 124 is disposed outside an end of the adjusting shaft 122 having the air inlet 1221. When the adjusting shaft 122 rotates relative to the base 121 and penetrates into the first passage 1213, the adjusting shaft 122 applies a force to the throttling assembly 123 to bias the throttling assembly toward the second passage 1214, so as to limit the equivalent flow area of the high-pressure gas flowing through the second passage 1214 and the first passage 1213, and reduce the flow rate of the high-pressure gas. In other words, if the force of the biasing element 124 on the throttling element 123 is smaller than the pressure of the high pressure gas ejected from the throttling element 123, and the displacement range of the throttling element 123 is not limited by the adjusting shaft 122, the high pressure gas can provide the predetermined maximum flow rate to the gas delivery pipe 110 through the second channel 1214, the first channel 1213 and the third channel 1223 according to the predetermined elastic force of the biasing element 124 and the pressure of the high pressure gas.

The supporting member 125 of the air pressure adjusting device 120 is a hollow sleeve member, and is sleeved on the portion of the adjusting shaft 122 outside the base 121. The support 125 includes an engaging portion 1251 and an internal thread 1252. The engaging portion 1251 is disposed on an inner wall of the support 125 and protrudes relative to the inner wall of the support 125. The support 125 is engaged with the adjusting shaft 122 by the engaging portion 1251. Specifically, the adjustment shaft 122 further includes a detent portion 1224 and a ramp 1225. The slot 1224 and the ramp 1225 are disposed on the outer wall of the adjustment shaft 122 and exposed from the base 121. The catching groove 1224 is disposed on the outer wall of the adjustment shaft 122 near the base 121. The chamfer 1225 is adjacent an end of the slot portion 1224 distal from the base 121. The height of the chamfer 1225 relative to the outer wall of the adjustment shaft 122 increases toward the pocket portion 1224. Thus, when the support member 125 and the adjustment shaft 122 are assembled, the assembling worker applies force to press the engaging portion 1251 of the support member 125 along the inclined surface 1225 of the adjustment shaft 122, and approaches the base 121. The engaging portion 1251 of the support 125 passes through the inclined surface 1225 and then engages with the engaging groove 1224 of the adjusting shaft 122. The end of the inclined surface 1225 adjacent to the slot portion 1224 can limit the movement of the engaging portion 1251 along the extending direction of the adjusting shaft 122 to prevent the support 125 from being separated from the adjusting shaft 122 along the outer wall of the adjusting shaft 122. The internal threads 1252 of the support 125 are disposed on an inner wall of the support 125 remote from the base 121. The internal threads 1252 are configured to thread with the plenum 110.

Please refer to fig. 3. Fig. 3 shows a partial cross-sectional view of the atomizer 100 shown in fig. 1 along the line B-B. The structure and operation of the nebulizer 100 according to the present embodiment will be described below with reference to the air pressure adjusting device 120 shown in fig. 2.

As shown in fig. 3, the air feed pipe 110 includes a body part 112, a socket part 114, a wing part 116, a fourth channel 118, a fifth channel 111, and an air feed channel 113. The main body 112 is a hollow cylinder and has an accommodating area 112a therein. The receiving area 112a is configured to store liquid medicine. The sleeve-joint part 114 is disposed at the bottom of the main body 112 (i.e. the end of the main body 112 close to the air pressure adjusting device 120), and extends toward the accommodating area 112a and the air pressure adjusting device 120. In the present embodiment, the sleeve 114 is connected to the main body 112 integrally, but the present invention is not limited thereto. The wing 116 is connected to the outer wall of the socket 114 and protrudes relative to the outer wall of the socket 114. The wing 116 is configured to be screwed with the internal thread 1252 (shown in fig. 2) of the support 125, so that the sleeve portion 114 is engaged between the support 125 and the adjusting 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 the present embodiment, the wing 116 is integrally connected to the outer wall of the sleeve 114, but the present invention is not limited thereto.

The fourth channel 118 is located in the socket 114 and communicates with the receiving area 112 a. The adjustment shaft 122 is partially threaded into the fourth channel 118 such that the third channel 1223 of the adjustment shaft 122 is in communication with the fourth channel 118 of the plenum 110. The width W1 of the fourth channel 118 (i.e., 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. Thus, when the wings 116 are threaded into the internal threads 1252 of the support 125, the outer wall of the adjustment shaft 122 may matingly engage the inner wall of the socket 114, forming an air-tight structure. Therefore, when the gas flows through the third passage 1223 and the fourth passage 118, the gas is prevented from leaking out from the joint between the sleeve 114 and the adjustment shaft 122.

Fourth passageway 118 has an outlet port 118a at an end of fourth passageway 118 extending into body portion 112. The width of the air outlet 118a (omitted from the drawing because the width is too small) is smaller than any width W1 of the fourth passage 118. For example, the width of the air outlet 118a is about 0.5-1.5 mm, and the width W1 of the fourth channel 118 is about 4-6 mm, but the invention should not be limited thereto.

The fifth channel 111 extends into the body 112 and is communicated with the fourth channel 118 and the accommodating area 112 a. The fifth passage 111 has a fluid inlet 111a, a fluid outlet 111b, and a stem 111 c. The fluid inlet 111a is located at an end of the fifth passage 111 remote from the fourth passage 118. Conversely, the fluid outlet 111b is located at an end of the fifth passage 111 near the fourth passage 118. Stem 111c spans fluid outlet 111b and is aligned with air outlet 118a of fourth passage 118. Therefore, the liquid medicine can be put in from the fluid inlet 111a, and after passing through the fifth channel 111, the liquid medicine flows into the accommodating area 112a of the body part 112 from the fluid outlet 111b to be stored. The stem 111c crosses the fluid outlet 111b to prevent the liquid medicine from blocking the air outlet 118a of the fourth passage 118.

The air duct 113 is connected to the outer wall of the body 112 and protrudes outward of the body 112 with respect to the outer wall of the body 112. The air duct 113 communicates with the accommodation area 112a in the body 112. The user can bring his mouth and nose close to the air outlet 113a of the air duct 113 away from the main body 112 to absorb the mist or droplets of the medicine in the main body 112.

The high pressure gas cylinder 130 has a port 132. The bottle opening 132 is engaged with an end of the base 121 of the air pressure adjusting device 120 remote from the adjustment shaft 122. Specifically, the outer wall of the mouth 132 has external threads 1321. The external threads 1321 of the bottle opening 132 are threaded with the internal threads 1212a of the second sleeve 1212 of the air pressure adjustment device 120. Thereby, the high pressure gas cylinder 130 and the air pressure adjusting means 120 are fixed. A membrane 1322 is attached to the 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 bottle 130 is screwed with the base 121 of the air pressure adjusting device 120 to approach the air pressure adjusting device 120, the boss 126 of the air pressure adjusting device 120 pierces the membrane 1322 on the bottle opening 132 to penetrate into the bottle opening 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 a screw-type manner. That is, in some embodiments, the high pressure gas cylinder 130 and the air pressure adjusting device 120 are fixed to each other by a locking manner of a protrusion and a groove, which should not be construed as a limitation to the invention.

As can be seen from the above structural configuration, in the atomizer 100 according to an embodiment of the present invention, when the stud 126 penetrates into the opening 132 of the high-pressure gas cylinder 130, the high-pressure gas in the high-pressure gas cylinder 130 flows to the pressure regulating device 120 along the second channel 1214. The pressure of the high pressure gas pushes the throttling element 123 toward the adjusting shaft 122 and the biasing element 124, so that the high pressure gas flows into the first passage 1213. Further, the high-pressure gas flows in from the inlet 1221 of the regulating shaft 122, passes through the third passage 1223 and the fourth passage 118 in sequence, and finally flows out from the outlet 118 a. According to the Bernoulli principle, after the high-pressure gas is sprayed out through the fine air outlet 118a, negative pressure is generated at the air outlet 118 a. The negative pressure sucks up the liquid medicine in the accommodating area 112a, so that the liquid medicine is torn into small water drops by the high-pressure gas flowing at high speed, and mist (droplets) filled in the air supply pipe 110 is formed.

By adjusting the adjustment shaft 122 to rotate in and out relative to the first channel 1213, the resultant force of the high-pressure gas applied to the throttle assembly 123 and the bias assembly 124 can be adjusted to control the pressure and flow rate of the high-pressure gas, thereby achieving the purpose of adjusting the mist size in a multi-stage manner.

Please refer to fig. 4. Fig. 4 shows a perspective view of a nebulizer 200 according to another embodiment of the invention. As shown in fig. 4, the atomizer 200 includes an air feeding pipe 210, an air pressure adjusting device 120 and a high pressure gas cylinder 130, wherein the air pressure adjusting device 120 and the high pressure gas cylinder 130 are the same as those in the embodiments shown in fig. 1 to 3, so that reference can be made to the above description, and further description thereof is omitted. The difference between the present embodiment and the embodiments shown in fig. 1 to 3 is that the air supply pipe 210 of the present embodiment is bent with respect to the air pressure adjusting device 120 and the high pressure gas cylinder 130. Specifically, the socket 214 of the blast pipe 210 has a bent section 214 a. The bending section 214a is bent with respect to the air pressure adjusting device 120 and the high pressure gas cylinder 130, for example, about 88 to 92 degrees, but the invention should not be limited thereto. Therefore, the air supply pipe 210 is bent and offset with respect to the air pressure adjusting device 120 and the high pressure gas cylinder 130.

As will be apparent from the above description of the embodiments of the present invention, the atomizer of the present invention controls the resultant force of the throttle assembly from the high pressure gas cylinder and the bias assembly by screwing in and out the adjusting shaft of the pressure adjusting device with respect to the base, thereby achieving the effect of adjusting the mist pressure in multiple stages. In addition, different from the existing portable atomizer, the atomizer can be used as a disposable atomizer by simplifying an air pressure adjusting structure and can be discarded after single use, so that the problems of medicine crystallization residue, durability problem of multiple use and poor atomization effect are solved.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
