[0034] Figure 1 An inhaler 10 according to an embodiment is schematically shown.

[0035] Figure 2 It is a plan view of the inhaler 10 according to an embodiment.

[0036] Figure 3 It is a front view of the inhaler 10 according to an embodiment.

[0037] Figure 4 It is a bottom view of the inhaler 10 according to an embodiment.

[0038] Referring to Figure 1 , the inhaler 10 according to an embodiment may include a main body 100, a cartridge 200, a first baffle group 300, and a second baffle group.

[0039] The main body 100 may include a first surface, a second surface facing the first surface, and a plurality of side surfaces surrounding the first surface and the second surface. The cartridge 200 may be coupled to the first surface. A mouthpiece may be provided on the second surface. Channels 110 and 120 penetrating the first surface and the second surface may be formed inside the main body 100. The channels 110 and 120 are channels for delivering an inhalable composition to the mouthpiece for the user to inhale. At this time, the channels 110 and 120 may be longitudinally divided into a first channel 110 and a second channel 120 from the first surface toward the second surface.

[0040] The first channel 110 or the second channel 120 may be formed in a swirl shape, with the end close to the second surface being spiral. Thus, a vortex can be generated in the flow of the inhalable composition.

[0041] In addition, the main body 100 may be provided with a flow distribution structure for controlling the inhalation degree of the inhalable composition at the end close to the second surface.

[0042] In addition, the main body 100 can be made of materials such as PLA, ABS, PC, PP, etc., or can also be made of other biodegradable (environmentally friendly) materials or metals.

[0043] The cartridge 200 can be coupled to the first surface of the main body 100. The interior of the cartridge 200 can accommodate an inhalable composition and can be in internal communication with the channels 110 and 120 inside the main body 100. The cartridge 200 can contain a single or multiple doses of the inhalable composition. The inhalable composition can include substances such as nicotine, nicotine salts, caffeine, taurine, vitamins, etc. In addition, the inhalable composition can also include flavoring particles, such as natural flavor particles, menthol, etc. The inhalable composition can be made in the form of, for example, a dry powder. At this time, the dry powder used in the inhaler 10 can be with or without a carrier.

[0044] The cartridge 200 can accommodate multiple inhalable compositions.

[0045] Specifically, the cartridge 200 can include a first accommodating member 210 and a second accommodating member 220.

[0046] The first accommodating member 210 and the second accommodating member each form a space inside the cartridge 200 and can be separated from each other by a partition wall.

[0047] The first accommodating member 210 can be in communication with the first channel 110 and accommodate the first inhalable composition A.

[0048] The second accommodating member 220 can be in communication with the second channel 120 and accommodate the second inhalable composition B. At this time, the size of the second inhalable composition B can be different from the size of the first inhalable composition A. In addition, the second inhalable composition B can be composed of materials different from those of the first inhalable composition A.

[0049] An air inlet 240 can be formed on one side of the cartridge 200. When suction is applied to the mouthpiece, air flows into the first accommodating member 210 or the second accommodating member 220 through the air inlet 240, and the accommodated inhalable composition can be transported along the channel to the mouthpiece with the airflow.

[0050] As described above, the first inhalable composition A and the second inhalable composition B can be transported through different channels respectively, whereby a user can inhale multiple inhalable compositions A and B into the body using one inhaler 10.

[0051] In addition, the cartridge 200 is detachably coupled to the first surface. Thus, when the inhalable composition contained in the cartridge 200 is exhausted, a new cartridge 200 can be replaced and installed on the main body 100. At this time, the cartridge 200 can be coupled to the main body 100 using a magnet, or can be coupled in a snap-fit manner by forming a groove 230 that matches the shape of the end of the main body 100.

[0052] A grid member may be provided between the main body 100 and the cartridge 200. The grid member may be made of the same material as the main body 100, such as polylactic acid (PLA), etc. In addition, the grid member may also be made of a metal with stable chemical properties and no inhalation toxicity, such as stainless steel, etc.

[0053] In addition, the inhaler 10 according to one embodiment is a device that uses the inertial force of the particles of the inhalable compositions A and B to deliver the inhalable compositions A and B containing dry powder, etc. When the size of the delivered inhalable composition particles is above a specified size, it may cause the user to cough. Therefore, as a filtering structure to prevent the inflow of particles of unspecified sizes, a plurality of baffles 310 and 410 arranged in a zigzag pattern may be provided.

[0054] In addition, the inhaler 10 according to one embodiment is a device capable of delivering a plurality of inhalable compositions A and B, and delivers a variety of dry powders by arranging a plurality of filtering structures with different particle-removing performances on both sides of the main body 100.

[0055] The first baffle group 300 may be provided in the first channel 110.

[0056] The second baffle group 400 may be provided in the second channel 120.

[0057] When suction is applied to the mouthpiece, the inhalable compositions A and B in the cartridge 200 can pass through the channels and be delivered to the mouthpiece. At this time, the first baffle group 300 and the second baffle group 400 can respectively control the particle size of the inhalable composition delivered to the mouthpiece.

[0058] For example, the first baffle group 300 can filter particles larger than a predetermined size in the first inhalable composition A passing through the first channel 110. The second baffle group 400 can filter particles larger than a predetermined size in the second inhalable composition B passing through the second channel. At this time, the predetermined sizes filtered by the first baffle group 300 and the second baffle group 400 may be different.

[0059] The first baffle group 300 and the second baffle group 400 may each be composed of a plurality of baffles.

[0060] The plurality of baffles 310 of the first baffle group 300 may be alternately spaced along the longitudinal direction on the inner wall of the first channel 110, as Figure 2 shown.

[0061] The multiple baffles 410 of the second baffle group 400 can be alternately spaced along the longitudinal direction on the inner wall of the second channel 120, as Figure 4 shown.

[0062] At this time, the baffles 310 of the first baffle group 300 and the baffles 410 of the second baffle group 400 can have different spacings, such as by comparing Figure 2 and Figure 4 shown.

[0063] In addition, by comparing again Figure 2 and Figure 4 , the lengths of the baffles 310 of the first baffle group 300 and the lengths of the baffles 410 of the second baffle group 400 can be different.

[0064] Next, taking the baffle 310 of the first baffle group 300 as an example, the structure of the baffle 310 or the baffle 410 will be described in detail.

[0065] The baffle 310 can include a first baffle member 3101 and a second baffle member 3102.

[0066] One end of the first baffle member 3101 can be fixed to the inner wall of the first channel 110 or the second channel 120, and the other end can extend toward the longitudinal center line of the first channel 110 or the second channel 120.

[0067] The second baffle member 3102 can further extend toward the center line in a manner forming an angle with the other end of the first baffle member 3101. The second baffle member 3102 can further extend beyond the center line of the first channel 110 or the second channel 120. The second baffle member 3102 can prevent particles larger than a predetermined size in the inhalable composition from passing through the first channel 110 or the second channel 120.

[0068] As described above, the inhaler 10 according to an embodiment can easily deliver inhalable compositions A and B of different sizes by arranging multiple baffle groups 300 and 400 with different particle removal performances in one main body 100.
