Therefore, other examples of exemplary embodiments may have different values.It should be noted that similar designations and letters refer to similar objects in the following drawings, so that a point defined once in one drawing does not need to be discussed further in later drawings.

[0018] The first embodiment, as shown in Figures 1, 2 and 5, is an adjustable breathing aid device comprising a filter nozzle 100, a housing 200 and a control mechanism 300. A continuous airflow channel is formed inside the housing 200. The airflow channel includes an inlet end and an outlet end. The filter nozzle 100 is positioned at the outlet end of the airflow channel. The filter nozzle 100 and the housing 200 are disassembled and reassembled by means of a removable structure. After the filter nozzle 100 and the housing 200 are separated by the removable structure, items such as aromatherapy products or fragrances are placed in the housing 200. Then, the filter nozzle 100 and the housing 200 are reassembled by means of the removable structure to deliver the aromatherapy through the breathing aid device.The housing 200 comprises an inner housing 201, an outer housing 202 and a base 203. The inner housing 201 and the outer housing 202 are both hollow and have a cylindrical structure with upper and lower openings. The outer housing 202 is placed on the outside of the inner housing 201. The base 203 is inserted into the bottom of the inner housing 201, and the base 203 and the inner housing 201 are fixed after the plug connection.

[0019] As shown in Figures 2 to 4, the control mechanism 300 comprises a connecting seat 301, a knob 302, and an insertion rod 307. The connecting seat is positioned at the inlet end of the airflow duct. The connecting seat 301 is inserted into the top of the inner housings 201, and the knob 302 is attached to the outside of the connecting seat 301 and can rotate around it to regulate the airflow size. The connecting seat 301 has an internal hollow cylindrical structure for connecting to the airflow duct of the housing 200. The connecting seat 301 is arranged with at least one adjustment air hole connected to the airflow duct. An annular round plate projects outward from the center of the connecting seat 301, and the underside of the annular round plate is tightly connected to the top of the inner housings 201, thus enabling a stable connection between the connecting seat 301 and the inner housings 201.

[0020] As shown in Figures 2, 3, and 5, the upper and lower ends of the connecting seat 301 are arranged with annular grooves. The first connecting plate 304 and the second connecting plate 305 are each arranged inside the two annular grooves. The first connecting plate 304 is located above the second connecting plate 305. The knob 302, the center of the first connecting plate 304, and the second connecting plate 305 are open with a through-hole. The insertion rod 307 is threaded into three round holes. The top of the insertion rod 307 is arranged with a hemisphere 309, and the diameter of the hemisphere 309 is larger than that of the insertion rod 307. The underside of the hemisphere 309 is in contact with the top of the knob 302. The insertion rod 307 is inserted into the round hole inside the second connecting plate 305 and then welded.and the axial displacement of the knob 302 is limited by the alignment of the second connecting plate 305 with the insertion rod 307, so that the knob 302 can only rotate and adjust.

[0021] The insertion rod 307 is arranged with a second spring 306, and the two ends of the second spring 306 are tightly connected to the first connecting plate 304 and the second connecting plate 305 respectively, and the first connecting plate 304 is pushed by the second spring 306 so that it rests against the inner wall of the knob 302 to improve the seal, while the second spring 306 can prevent the first connecting plate 304 from rotating with the knob 302 to ensure the stability of the first connecting plate 304.

[0022] Furthermore, the top of the knob 302 is arranged with a first air hole 303, and the adjustment air hole is the third air hole formed between the first connecting plate 304 and the annular groove on the top of the connecting seat 301. The first air hole 303 is the same size as the third air hole. By turning the knob 302, the knob 302 drives the first air hole 303 to rotate, and the airflow size of the breathing device is regulated by changing the overlap area between the first air hole 303 and the third air hole. With a large overlap area, the airflow that can be circulated is large, and with a small overlap area, the airflow that can be circulated is small, which is convenient for the user to adjust the suction power to their needs.

[0023] As shown in Figure 5, the removable structure includes an external thread 101 arranged on the filter nozzle 100, and an internal thread 102 arranged in the base 203. A removable connection between the external thread 101 and the internal thread 102 can be made by means of a threaded connection between the filter nozzle 100 and the housing 200 to facilitate the disassembly and assembly of the filter nozzle 100 and the housing 200.

[0024] As shown in Figures 1 and 2, the external rotation of the connecting seat 301 is connected to a collar 400, the collar 400 is U-shaped and the collar 400 is arranged with a connecting rope 500, by means of the connecting rope 500 the breathing aid device can be hung around the neck, which is convenient to use at any time and can also prevent it from falling off.

[0025] In the second embodiment, as shown in Figures 6 to 10, based on embodiment 1, the external thread 101 and the internal thread 102 are omitted, the underside of the second connecting plate 305 is arranged with a first spring 600, the top of the filter nozzle 100 is arranged with a first inner tube 103, a through-hole 109 is opened in the first inner tube 103, aromatherapy or fragrance is introduced into the first inner tube 103, two corresponding connecting holes are opened in the first inner tube 103, and a connecting rod 105 is inserted inside the connecting hole, the underside of the first spring 600 rests closely against the connecting rod 105 and also includes a second inner tube 104, which is arranged inside the inner housings 201, two L-shaped sliding holes 106 are opened in the second inner tube 104, and the connecting rod 105 slides in the sliding hole 106 ordered.Where the sliding hole 106 encompasses the first sliding part and the second sliding part, while the connecting rod 105 is located in the first sliding part, the filter nozzle 100 moves up and down through the first inner tube 103; when the connecting rod 105 is located in the second sliding part, the filter nozzle 100 rotates through the first inner tube 103, when the filter 100 needs to be fixed, the connecting rod 105 is moved upwards along the first sliding part and the first spring 600 is compressed, and then the filter nozzle 100 is rotated, whereby the filter nozzle 100 drives the connecting rod 105 to move inwards into the second sliding part to limit the filter nozzle 100, so that the filter nozzle 100 is attached to the housing 200.If the filter nozzle 100 needs to be disassembled, the filter nozzle 100 is rotated so that the connecting rod 105 is in the first sliding part; at this time, the connecting rod 105 will move under the action of the first spring 600, so that the filter nozzle 100 is ejected downwards, so that the filter nozzle 100 is separated from the housing 200.

[0026] Furthermore, a sealing groove 108 is open on the filter nozzle 100, and the inside of the sealing groove 108 is fitted with a sealing ring 107; the sealing ring 107 seals the filter nozzle 100 and the housing 200 to improve the air seal of the breathing aid device.

[0027] In the third embodiment, as shown in Figure 4, the arrangement of the third air hole is omitted based on the first embodiment. The adjusting air hole is the second air hole 308, which is open at the top of the first connecting plate 304. The second air hole 308 has three holes, and the three second air holes 308 are arranged with the round hole as their center point in an equidistant circular circumference. The first air hole 303 and the second air hole 308 are arranged mutatis mutandis. By turning the knob 302, the first air hole 303 overlaps with the second air hole 308. By changing the overlap area between the first air hole 303 and the second air hole 308, the airflow size of the breathing device is adjusted. With a large overlap area, the airflow that can be circulated is large, and with a small overlap area, the airflow that can be circulated is small, which is convenient for the user.to adjust the suction power to his needs.

[0028] In other embodiments (not shown in the figure), the control mechanism 300 comprises a connecting seat 301 and a sliding damper. The connecting seat 301 is inserted into the top of the inner housings 201, and its side wall is arranged with a long adjustment window (corresponding to an adjustment air hole) along the axial direction. The sliding damper has an arc or annular sleeve and is tightly encased on the outside of the connecting seat 301 so that it can be slid up and down along the axis of the connecting seat 301. The sliding damper is arranged with a damper hole that corresponds to the shape and size of the adjustment window. The housings 200 (or the outside of the connecting seat 301) are arranged with a slide or guide rail in which the sliding damper is embedded to restrict its movement to axial sliding only.The outer surface of the sliding damper features a flange or anti-slip pattern that allows for easy sliding and pulling with the fingers. The user slides the damper up and down to change the overlap between its damper hole and the adjustment window on the 301 connecting seat. When the two holes fully overlap, the airflow channel is at its widest; when the sliding damper completely covers the adjustment window, the airflow channel is minimal (or completely closed, depending on the design); the intermediate position provides stepless, linear airflow control. Compared to rotary adjustment, sliding adjustment can be more intuitive, and the user's perception of the opening is more direct. The design is relatively simple, and the number of parts can be reduced.

[0029] In other embodiments (not shown in the figure), the method for directly placing the aromatherapy material into the housing 200 is modified to a pre-packaged, replaceable aromatherapy capsule. Inside the housing 200, above the base 203, a separate, removable aromatherapy capsule compartment is arranged. The aromatherapy capsule compartment is a small container (e.g., a mesh tray, a porous ceramic tray) with ventilation holes (on the top and / or sides). Its shape is designed to include specific slots for easy insertion and removal of the housing 200. The front end of the aromatherapy capsule compartment can be designed with a pull ring or push button for easy operation. The corresponding position inside the housing 200 is arranged with a slot that matches the shape of the aromatherapy capsule compartment to ensure that, after insertion, airflow passes through the aromatherapy material in the capsule compartment.The connection method between the filter nozzle 100 and the housing 200 can employ the threaded connection of the first embodiment (external thread 101 / internal thread 102) or the spring-loaded buckle connection of the second embodiment. When the aromatherapy capsule needs to be replaced, only the filter nozzle 100 (which can be unscrewed or popped out) needs to be opened, the aromatherapy capsule compartment pulled out, and the capsule compartment, pre-loaded with the new aromatherapy material, reinserted. Then the housing 200 is inserted, and finally the filter 100 is reloaded. This avoids direct contact with the aromatherapy capsules / fragrances by the user, making it more hygienic, convenient, and tidy.The specifications and volumes of aromatherapy capsules can be standardized, which facilitates the commercial sale of refills of different fragrance types, thereby reducing the need to clean the inner casing.

[0030] In other embodiments (not shown in the figure), the external thread 101 and the internal thread 102 are omitted, or the snap-fit ​​structures such as the first inner tube 103, the connecting rod 105, the sliding hole 106, and the first spring 600 in the second embodiment are omitted. One or more first magnets (such as NdFeB magnets) are embedded at the lower edge of the filter nozzle 100 (or at a specific location on the inside). One or more second magnets are embedded at the top of the base 203 of the housing 200 (or at the corresponding position on the upper edge of the inner housing 201), and the arrangement of the poles ensures mutual attraction with the first magnet.The contact surfaces on the underside of the filter nozzle 100 and on the top of the base 203 (or the inner housing 201) can be designed with a knurled fit or a locking pin (not shown) to ensure correct alignment and an airtight seal during adsorption. Optionally, a small slot or notch is provided on the outside of the filter nozzle 100 or on the outside of the base 203 to facilitate finger insertion for separation. When assembling the filter nozzle 100, it simply needs to be aligned with the top of the housing 200, and the magnet will automatically engage and lock as it approaches. To remove the filter nozzle 100, a pulling or levering force is applied that overcomes the magnetic attraction, resulting in a quick separation. Operation is extremely convenient and can be performed with one hand, providing a good user experience.It avoids the fatigue failure problems that can occur with thread wear or snap-fit ​​structures. It should be noted that the selection of magnets should ensure that the adsorption force is sufficient to withstand the tensile force in normal use, but should not unduly impede disassembly.

[0031] In other embodiments (not shown in the figure), modifications are made based on the third embodiment (a second air hole 308 is open on the connecting plate). At the lower edge of the inside of the knob 302, around its central round hole, a circle of toothed or cam-like structures with several (such as 3-6) openings of different shapes or sizes (first vent 303 variant) is arranged. The top of the first connecting plate 304 is attached (or is itself part of the top of the connecting seat 301), on which a fixed air inlet hole of a fixed size and shape is arranged accordingly (corresponding to an adjustment air hole). A damping element, such as a silicone damping disc, a miniature spring plunger structure, or a viscous damping grease, is added between the knob 302 and the first connecting plate 304 (or a specific location inside the knob 302).When the user turns knob 302, a distinct gear tactile feedback is felt (provided by the damping elements and the positioning of the various openings). Each gear corresponds to a different opening on knob 302, aligning with the fixed air inlet hole on the first connecting plate 304. Different opening designs (e.g., round holes of various sizes, fan-shaped holes, multi-hole combinations, etc.) offer preset, discrete airflow size options (e.g., small, medium, large, closed). The damping enhances the texture and precision of knob 302's operation to prevent accidental touches and clearly indicate the current gear. Compared to continuously adjustable ring grooves or sliding dampers, this multi-gear design is simpler, more reliable, and more user-friendly, making it suitable for users who prefer preset gears. The airflow damping optimizes the user experience.

[0032] In summary, the present utility model achieves the following technical effects: The airflow size of the breathing device is regulated by changing the overlap area between the first air hole 303 and the adjustment air hole. A larger overlap area results in a large airflow, while a smaller overlap area results in a smaller airflow, allowing the user to adjust it comfortably to their needs.

[0033] In the description of this utility model, it should be understood that the orientation or position relationship represented by orientation terms such as "front, back, top, bottom, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is normally based on the orientation or position relationship shown in the accompanying drawings and serves only to facilitate the description of this utility model and to simplify the description, and in the absence of a statement to the contrary, these orientation terms do not indicate or imply that the device or element referred to must have a particular orientation or must be designed and operated in a particular orientation, so that this cannot be understood as a limitation of the scope of protection of this utility model;The terms "inside, outside" refer to the inside and outside of the outline relative to the parts themselves.

[0034] To simplify the description, relative spatial terms such as "above...", "above...", "superficial to...", "above...", etc., can be used to describe the spatial relationship between a device or feature depicted in the image and other devices or features, as shown in the illustration. It should be understood that these relative spatial terms are intended to encompass various orientations in use or operation that differ from the position depicted in the image. For example, if the device depicted in the drawings is inverted, a device described as "above another device or structure" or "above another device or structure" will then be positioned as "below another device or structure" or "under another device or structure." Therefore, the exemplary term "above..." can mean both "above..."“ and “under…” represent two positions. The device can also be positioned in other different ways (rotated 90 degrees or in a different orientation), and the relative description of the space used here will be explained accordingly.

[0035] Furthermore, it should be noted that the use of terms such as "first," "second," etc., to delimit parts serves only to distinguish the respective parts. Unless otherwise specified, the aforementioned terms have no special meaning and should therefore not be understood as limiting the scope of protection of this utility model.

[0036] The above description is only a preferred embodiment of the present utility model and is not used to limit the present utility model, and the present utility model may have various modifications and variations for personnel trained in the field. All modifications, equivalent replacements, improvements, etc., made in accordance with the spirit and principles of the present utility model fall within the scope of protection of the present utility model.
