For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] Example 1

[0029] like Figure 1-4As shown, the utility model provides a technical solution: an anti-misoperation structure of a powder aerosol dispenser, comprising: a main body mechanism 1, an anti-touch mechanism 2 is provided on one side of the main body mechanism 1, the main body mechanism 1 includes a hollow cavity 11, an outer ring 14 is provided on the outside of the hollow cavity 11, a hollow cavity 2 19 is provided at one end of the outer ring 14, an inner matching disk 13 is provided on the inner side of the outer ring 14, a sliding ball 15 is provided on the top and bottom sides of the inner matching disk 13, and the surfaces of the sliding ball 15 are respectively provided with the hollow cavity 11 and the hollow cavity 2 19, a material box 12 is provided on the top side of the hollow cavity 11, a material feed port 16 is provided at one end of the material box 12, a accommodating cavity 111 is provided at the bottom end of the hollow cavity 2 19, and the hollow cavity 11 A side plate 112 is provided on the top side, a material box 12 is provided on the outside of the side plate 112, a transverse plate 115 is provided on one side of the material box 12, a limiting rod 113 is provided inside the transverse plate 115, the interior of the transverse plate 115 is connected with one end of the limiting rod 113, a spring 114 is provided at one end of the limiting rod 113, a transverse plate 115 is provided at the other end of the spring 114, a side plate 112 is provided at one end of the limiting rod 113, a guide mark 17 is provided on one side of the inner matching disk 13, a guide mark 2 18 is provided at one end of the guide mark 17, a hollow cavity 2 19 is provided on one side of the guide mark 2 18, a scraper 110 is provided on the bottom of the inner matching disk 13, and a positioning hole 116 is provided on one side of the outer ring 14.

[0030] In this embodiment, when the powder aerosol dispenser of this type is operated, the inner distribution disc 13 is rotated, and during the rotation process, the guide mark 17 and the guide mark 2 18 are observed to be in correspondence. When they are in correspondence, the discharge port of the material box 12 will correspond vertically to the feed port 16, so that the objects in the material box 12 will enter the interior of the hollow cavity 2 19 along the path, thereby realizing the directional conveying of the powder aerosol and ensuring that the powder aerosol flows along the established path. At this time, by rotating the inner distribution disc 13 again, the feed port 16 no longer corresponds to the discharge port. At the same time, in this process, since a scraper 110 is installed at the bottom of the inner distribution disc 13, the objects in the hollow cavity 2 19 will be scraped into the receiving cavity 111. Therefore, in this way, the dosage and dosage position of the powder aerosol can be effectively controlled, and the release of the drug can be accurately controlled to ensure the accuracy and controllability of the drug administration.

[0031] Secondly, by pulling out the limit rod 113, the limit rod 113 no longer restricts the side panel 112, and the fixation between the side panel 112 and the material box 12 is also released. When the material box 12 needs to be installed, the material box 12 is vertically aligned with the side panel 112, and then the limit rod 113 is snapped into the side panel 112, thereby completing the connection between the side panel 112 and the material box 12 again.

[0032] Example 2

[0033] like Figure 1-4As shown, the anti-touch mechanism 2 includes an arc-shaped plate 21, the inner side of one end of the arc-shaped plate 21 is fixedly connected to one end of the insertion rod 24, the other end of the insertion rod 24 fits into the inner surface of the positioning hole 116, the top of the arc-shaped plate 21 is fixedly connected to the bottom end of the protrusion 22, one side of the protrusion 22 is fixedly connected to the other end of the spring 23, and the other end of the spring 23 is fixedly connected to one side of the hollow cavity 11.

[0034] In this embodiment, by docking the inner side of the arc plate 21 on the exposed part of the inner matching disk 13, and combining the insertion rod 24 on the arc plate 21 with the outer ring 14, the exposed part of the inner matching disk 13 can be covered to prevent personnel from accidentally touching the inner matching disk 13 during operation, thereby improving the safety of the equipment and preventing the inner matching disk 13 from rotating arbitrarily and causing the material to flow out of the material box 12 uncontrollably. Therefore, the installation of the anti-touch mechanism 2 can effectively reduce the risk of accidents. In addition, the installed spring 23 is connected to the protrusion 22, which can effectively prevent the arc plate 21 from being hung on the outside of the hollow cavity 11 when not in use to prevent it from being lost.

[0035] Working principle:

[0036] like Figure 1-4 As shown, by rotating the inner distribution disc 13, and observing whether the guide mark 17 and the guide mark 2 18 are in correspondence during the rotation, when they are corresponding, the discharge port of the material box 12 will correspond vertically to the feed port 16, so that the objects in the material box 12 will enter the interior of the hollow cavity 2 19 along the path, realizing the directional conveying of the powder aerosol and ensuring that the powder aerosol flows along the established path. At this time, by rotating the inner distribution disc 13 again, the feed port 16 no longer corresponds to the discharge port. At the same time, in this process, since a scraper 110 is installed at the bottom of the inner distribution disc 13, the objects in the hollow cavity 2 19 will be scraped into the cavity 111. Therefore, this method can effectively control the dosage and dosage position of the powder aerosol.

[0037] By docking the inner side of the arc plate 21 against the exposed part of the inner matching disk 13 and combining the insertion rod 24 on the arc plate 21 with the outer ring 14, the exposed part of the inner matching disk 13 can be covered to prevent personnel from accidentally touching the inner matching disk 13 during operation, thereby improving the safety of the equipment.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0039] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
