Background

A compression type (compressed air type) atomizer belongs to one type of atomizers. The atomizer is applied to inhalation therapy which makes atomized liquid medicine directly act on nasal cavity, upper respiratory tract, bronchus, etc., the liquid medicine particles atomized by the atomizer are fine, and easily go deep into bronchus, bronchiole and alveolus of lung through breathing, thus being suitable for direct absorption by human body. This compression atomizer utilizes the air compressor pump to provide compressed air, and the atomizer host computer is arranged in to the compressor pump, and the host computer passes through the pipe to be connected with the atomizing cup, and compressed air passes through the pipe and gets into the atomizing cup, and the while has liquid in the atomizing cup storage. The atomizing cup utilizes the Venturi effect to enable liquid and compressed air to collide at high speed, the liquid is atomized to form liquid mist, and the liquid mist is composed of air, coarse particle liquid beads and fine particle liquid beads. Wherein, fine particle liquid pearl and air mixture form aerosol, and thick particle liquid pearl can be blockked by the interior filter kit of atomizing cup and filter, and only aerosol part gets into the face guard that atomizes through the specific passageway of atomizing cup, and then these medicine fog are inhaled the human body by respiratory.

However, most medical compressed air nebulizing cups are inefficient in nebulization and must be adapted to air compressor pumps with power of over one hundred watts. If the power of the compression pump is insufficient, the atomizing amount (liquid medicine atomizing rate per minute, unit ml/min) of the atomizing cup is insufficient, the liquid medicine atomizing particles (the diameter of single liquid particle in the medicine mist, unit mum) are large, or the mist does not appear at all. The high-power compression pump needs to be externally connected with 220V mains supply, so that the atomizer cannot be carried outside for use, and serious inconvenience is brought to patients who need to go out frequently.

This structure can make from the liquid outlet 213a exhaust liquid W can directly cover gas outlet 212a, compares with prior art directly discharges compressed gas in holding chamber 211, and the reducible compressed gas of this scheme causes the condition of pressure reduction because holding chamber 211 space is too big after spouting from gas outlet 212a, makes compressed gas have higher pressure when contacting with liquid, improves compressed gas to the atomizing efficiency of liquid.

It is desirable that the lowest edge of the outlet wall of the outlet port 213a is flush with the highest edge of the outlet port 212a, but if the flush is optimal, there may be a processing error during the actual processing, so that the two are not flush, but one of them is slightly higher, which is also defined as flush in this application.

Of course, referring to fig. 20 and 23, in other embodiments, the lowest edge of the outlet wall of the liquid outlet 213a of the atomizing cup 200 may be higher than the highest edge of the gas outlet 212a, i.e. the gas outlet 212a is lower than the liquid outlet 213a, so that the compressed gas exits the gas outlet 212a through a diffusion path before contacting the liquid W.

Further, referring to fig. 6, 14 and 17, in some embodiments, the liquid channel 213 has at least two channels, which are disposed at different positions of the atomizing channel 214. The at least two liquid passages 213 can deliver more liquid W into the atomizing channel 214, thereby allowing the liquid W to be in full contact with the compressed gas, further improving the atomizing efficiency. Moreover, the more liquid channels 213 can make the compressed gas discharged from each region of the gas outlet 212a contact with the liquid W as much as possible, so as to avoid that the compressed gas in a certain region of the gas outlet 212a cannot contact with the liquid W in time due to a single liquid outlet 213a, thereby losing energy of the compressed gas and reducing atomization efficiency.

Referring to fig. 6, 14, 17 and 23, in one embodiment, the liquid outlets 213a of the at least two liquid passages 213 are distributed in a rotational symmetry manner with the axis of the atomizing cavity 214 as the center. The distribution of the liquid outlets 213a can make the liquid W uniformly discharge the liquid W from at least two directions of the gas outlet 212a, so that the liquid W is more uniformly distributed to each region of the gas outlet 212a, and the atomization efficiency is further improved.

Referring to fig. 20, in one embodiment, the liquid outlets 213a of at least two liquid passages 213 are arranged with their center lines staggered. The offset arrangement means that the center lines of the liquid outlets 213a are not converged on the central axis of the atomizing channel 214, but are arranged in different directions. Since the center lines of the liquid outlets 213a are offset, the liquid W may generate liquid flows in different directions at the moment of being discharged from the liquid outlets 213a, and thus more areas may be covered. And collision is possibly generated among all liquid flows, so that the liquid flows are splashed, atomization is facilitated, and the atomization efficiency is improved.

Further, in one embodiment, the center lines of the liquid outlets 213a of the at least two liquid passages 213 are arranged in parallel. The arrangement enables the liquid W to form a liquid vortex in the atomizing channel 214 after being sprayed, so that the liquid W and the compressed air are contacted and collided more fully, and the atomizing efficiency is improved. Of course, other forms of offset arrangements may be used in addition to such parallel arrangements.

Further, referring to fig. 6, in an embodiment, the compressed gas channel 212 is disposed from the bottom to the top, and the gas outlet 212a is located at the upper portion of the compressed gas channel 212. The aerosol passage 215 communicates with the air outlet 212a, and the mist outlet 214a is located vertically above the air outlet 212 a. The liquid outlet 213a is arranged on the side wall of the atomizing cavity 214. This atomizing chamber way 214 sets up with compressed gas passageway 212 is vertical, and goes out fog mouth 214a and be located the vertical top of gas outlet 212a, can make compressed gas directly spout towards a fog mouth 214a position, reduces other chamber walls or structure and to the hindrance of compressed gas and the energy loss that causes, further improves atomizing efficiency.

The tapered end 2211 extends into the corresponding tapered docking cavity 245 to communicate the gas outlet 212a of the compressed gas passage 212 with the end of the atomizing channel 214 with a smaller opening. The matching of the tapered docking cavity 245 and the tapered end 2211 of the convex column 221 can make the air outlet 212a on the convex column 221 and the liquid outlet 213a on the atomizing cup 240 as close as possible, and especially when the inclined liquid channel 213 as shown in fig. 23 is provided, the problem that the thickness of the atomizing cup 240 is too large and the liquid outlet 213a is difficult to be close to the air outlet 212a due to the structure can be reduced.

Further, in one embodiment, the atomizing channel 214 has at least one section of cavity gradually enlarged from a side of the compressed gas channel 212 to a side of the mist outlet 214a for diffusing the liquid mist.

Referring to fig. 6, 14 and 17, more specifically, the nebulizing channel 214 includes a first nebulizing channel 2141 and a second nebulizing channel 2142. The liquid outlet 213a and the gas outlet 212a are both communicated with the first atomization channel 2141, the second atomization channel 2142 is communicated with the first atomization channel 2141, the mist outlet 214a is located on the second atomization channel 2142, and the cavity size of the second atomization channel 2142 is larger than that of the first atomization channel 2141, so that the liquid mist can be diffused. The second atomization channel 2142 can be tapered or otherwise shaped. The taper may comprise a conical or pyramidal shape.

The mist outlet 214a, the liquid outlet 213a and the air outlet 212a in the above embodiments can be circular, rectangular and various conventional or unconventional shapes, respectively.

Further, the aerosol filter 250 has filter passages to allow the passage of the aerosol and to block the passage of large water droplets that do not form the aerosol. Referring to fig. 3, 4, 5, 9 and 10, in one embodiment, the aerosol filter pack 250 has a mounting cartridge (251 and 252 are shown as an example of a mounting cartridge) and a plurality of vanes 255. The blades 255 are spirally mounted on the inner wall of the mounting cylinder, and gaps are formed between adjacent blades 255 to form a plurality of obliquely arranged curved channels for facilitating the aerosol to pass through.

As the aerosol passes through the tortuous path between the vanes 255, some of the large droplets may be blocked by the vanes 255 and condense on the vanes 255 and fall back into the cup 220. However, the aerosol in the aerosol can pass through the bent channel, so that the first aerosol filtration is realized.

With continued reference to fig. 3, 4, 5, 9 and 10, in one embodiment, the end of the blade 255 near the wall of the mounting cylinder is fixed to the mounting cylinder, and the end of the blade away from the wall of the mounting cylinder converges toward the middle of the mounting cylinder and defines a second channel in the middle of the mounting cylinder for the passage of the aerosol. The second passage may be a circle or other shape that increases the area through which the aerosol passes, which may increase the throughput of the aerosol. However, too large a second passage may also lead to the passage of some large droplets, and the second passage may therefore be sized according to the desired atomization effect.

The mounting sleeve may be directly mounted to the cup 220, such as by a snap fit or other secure connection. Specifically, the mounting cylinder includes an inner cylinder 251 and an outer cylinder 252, and the outer cylinder 252 is covered outside the inner cylinder 251 and connected with the inner cylinder 251 through a connecting rib 253. Air inlet holes 254 are reserved between the connecting ribs 253. The outer cylinder 252 can be mounted on the cup 220, and the air inlet hole 254 can be directly communicated with the receiving cavity 211 of the cup 220. The inner cylinder 251 may be supported on the bracket 230, for example, the support portion 232 of the bracket 230.

Further, referring to fig. 3, 4, 5 and 11, in an embodiment, the upper cover 260 has a cylindrical structure. The tubular structure has a curved, continuous, curved channel. One end of the continuous curved path is in abutting contact with the aerosol filter 250 and the other end is the aerosol outlet 215 a.

The large droplets in the mist do not pass through the tortuous path, and the aerosol portion of the mist can pass through the tortuous path, so that the large droplets will condense on the wall of the upper cap 260 and fall back into the cup 220, thereby achieving a second aerosol filtration, and the aerosol 413 will eventually reach the aerosol outlet 215a of the upper cap 260 and enter the aerosolization mask 320 or the mouthpiece 310.

In the above embodiment, the continuous curved path of the lid 260, the curved path of the aerosol filter 250, and the receiving cavity 211 of the cup 220 are communicated to form the aerosol passage 215. In other embodiments, other structures may be used to form the aerosol passage 215.

Further, with continued reference to fig. 3, 4, 5 and 11, in one embodiment, the upper cover 260 further includes a skirt 261, the skirt 261 having a notch 262. The cylindrical structure of the upper cap 260 is inserted into the inner tube 251 of the aerosol filter 250, and the skirt 261 abuts against the outer tube 252 of the aerosol filter 250. The notches 262 in the skirt 261 communicate with the inlet holes 254 of the aerosol filter 250 to form an inlet air passage. The air inlet channel allows air outside the atomizing cup 200 to enter the cup as shown by an arrow D in fig. 5, and finally to be ejected out of the aerosol outlet 215a together with the aerosol 413, so as to accelerate and increase the amount of mist generated by the atomizing cup 200. The motive force for this portion of the air flow is from the venturi effect created by the gas flow within the cup 220.
