Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of quantitative aerosol driver, especially, a kind of indication type inhalation aerosol driver is completed with mechanical structure to indicate the purpose of counting. BACKGROUND

[0002] Asthma, Chronic Obstructive Pulmonary Disease,

[0003] COPD) are the two most serious diseases in respiratory diseases, and pulmonary inhalation administration has become a relatively mature common treatment for respiratory diseases at present, and the inhalation administration using quantitative aerosol driver has become the main path selected by the drug for the treatment of respiratory diseases.

[0004] Quantitative aerosol driver is characterized in that, during the use of patients, each press administration can accurately give the set dose of liquid medicine, which is convenient for the inhalation therapy of patients. But the common aerosol bottle and driver device on the market are opaque materials, which makes patients unable to accurately judge the residual amount of aerosol bottle. When quantitative aerosol is about to run out, the last few times of pressing use cannot guarantee the accuracy of drug dose. This promotes the research and production of counting quantitative aerosol driver.

[0005] In the prior art, the aerosol driver using mechanical structure to complete the counting purpose adopts independent elastic structure to complete the reset action of counting component, so that the counting component can return to the initial state after completing the transmission counting, so as to start the next counting action. But this way makes the return action of counting component separate from the return action of aerosol bottle. In the use process of the whole device, the elastic structure of counting component and the elastic structure contained in aerosol bottle may be attenuated to different degrees, so that the actions in the counting process are out of sync, which finally leads to miscounting.

[0006] Meanwhile, existing aerosol actuators use an integrated counting component, with the counting component's structure encased in a housing to form an independent component located within the actuator housing. This limits the driving structure that contacts the aerosol bottle. The counting component is driven via a circumferential platform at the aerosol bottle opening. During use, the valve stem end is fixed inside the actuator housing, while the counting component is located between the valve stem actuator housing and the circumferential platform at the aerosol bottle opening. The lower end of the counting component is fixed against the inside of the actuator housing. Currently, the distance from the circumferential platform at the bottle opening to the valve stem end varies among aerosol bottle manufacturers. This means that only aerosol bottles from specific manufacturers can accurately trigger the counting process of the counting component. When changing aerosol bottle manufacturers, the coordination and linkage of the counting component need to be recalculated and designed, resulting in low adaptability of the overall counting component.

[0007] Currently, especially for counting components that are driven by the end face of the aerosol bottle, the presence of internal elastic components during the installation of the whole device means that the counting component is in a ready-to-use state during installation. At this time, the aerosol can needs to be pressed into the driver. If the pressing action is not controlled, the counting component will be accidentally triggered. After the accidental triggering, the display of the counting component needs to be readjusted, which increases the difficulty and time of the installation of the whole device. Utility Model Content

[0039] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0040] Figures 1 to 10 A preferred embodiment of this indicative counting aerosol driver is shown.

[0041] For example, similar to traditional structures, it also includes: an aerosol bottle 1, a counting assembly 2, and a driver housing 3, among other structural components. Among them:

[0042] like Figures 1 to 3 As shown, the counting component 2 is positioned between the aerosol bottle 1 and the driver housing 3. A fan-shaped display window 31 is located on the back of the driver housing 3, allowing the user to observe the internal counting component 2 and easily obtain information about the remaining dosage inside the aerosol bottle 1. An indicator tip 32 is provided inwards from the upper edge of the display window 31 to help determine the remaining dosage range, preventing cognitive errors when two numbers are displayed in the display window 31 area, avoiding misjudgment of the remaining usable dosage inside the aerosol bottle 1, and ensuring that the user can promptly purchase a new aerosol bottle 1 or a new aerosol driver. The counting component 2 includes an aerosol bottle sleeve 21, a number wheel 22, a transmission wheel 23, and a counting base 24. The upper part of the aerosol bottle sleeve 21 is fitted around the mouth of the aerosol bottle 1, while its lower end penetrates and connects to the counting base 24. The number wheel 22 and the transmission wheel 23 are fixed to the counting base 24, forming a right angle and contacting each other.

[0043] like Figure 4 As shown, the upper end of the aerosol bottle sleeve 21 is provided with multiple fasteners 211, which are used to engage with the aerosol bottle.

[0044] The stepped openings of the aerosol bottle 1 interlock, allowing the aerosol bottle sleeve 21 to be fixed onto the aerosol bottle 1, with both moving synchronously. The lower end of the aerosol bottle sleeve 21 is equipped with a single top finger 212, multiple uprights 213, and multiple guide arms 214. The top finger 212 is angled downwards at a certain acute angle from the lower end of the ring of the aerosol bottle sleeve 21, and the top finger 212 has…

[0045] The guide arm 214 has a certain length and will deform to some extent during the downward movement of the aerosol bottle sleeve 21. The length of the guide arm 214 is greater than the vertical height of the top finger 212. A right-angled triangular buckle structure is provided at the far end of the guide arm 214. The guide arm 214 will pass through the reserved space on the counting base 24, allowing the aerosol bottle sleeve 21 to be movably connected to the counting base 24 vertically. At the same time, the acute angle of the buckle structure points outward, which will limit the upward movement distance of the aerosol bottle sleeve 21, making it easy for the user to prevent the aerosol bottle sleeve 21 from falling off when replacing a new aerosol bottle 1. The extension height of the column 213 is less than the vertical height of the top finger 212 and the guide arm 214. When the aerosol bottle 1 is pressed down, the bottom surface of the column 213 contacts the circumferential top surface of the counting base 24, limiting the downward movement distance of the aerosol bottle sleeve 21, which facilitates the assembly and fixation of the aerosol bottle 1 and the aerosol bottle sleeve 21.

[0046] like Figures 5-6 As shown, the numbers N-0 are arranged sequentially around the circumference of the digital wheel 22, where N is a number greater than 1. The numbers decrease by a fixed value, and the specific value of N can be adjusted according to the internal standard dosage of the aerosol bottle 1, often using 200 or 120. A limiting recess 221 is provided on the coaxial circumference of the digital surface of the digital wheel 22. The limiting recess 221 is hemispherical in shape, and a stop bar 222 is provided in the inward extension range of the limiting recess 221. The position of the stop bar 222 corresponds to the position of the outer number 0.

[0047] The digital wheel 22 and the transmission wheel 23 are in contact at a right angle. The outer periphery of the transmission wheel 23 is provided with ratchet 231, which has ten teeth. A single transmission paddle 232 is provided on a plane opposite to the ratchet 231, and the tooth height of the transmission paddle 232 is higher than that of the ratchet 231. A ring of transmission ratchet 223 is provided around the non-digital surface of the digital wheel 22. When the transmission wheel 23 completes one revolution, the transmission paddle 232 contacts the transmission ratchet 223, and the transmission ratchet rotates once. That is, when the transmission wheel 23 is paddled 10 times, the digital wheel is paddled once.

[0048] like Figures 7-8As shown, the counting base 24 has two slots for placing the digital wheel 22 and the transmission wheel 23 respectively. A laterally extending anti-reverse support arm 245 is provided in the slot for placing the transmission wheel 23. The end face of the anti-reverse support arm 245 is triangular and beveled. This end face will mesh with the ratchet 231 on the transmission wheel 23. When the transmission wheel 23 may be misaligned or accidentally rotate slightly counterclockwise, the triangular bevel of the anti-reverse support arm 245 will engage with the ratchet 231, preventing the transmission wheel 23 from rotating counterclockwise.

[0049] The counting base 24 has a stop block 242 in the slot for holding the digital wheel 22. The position of the stop block 242 corresponds to the position of the stop bar 222 on the digital surface of the digital wheel 22. When the stop bar 222 of the digital wheel 22 reaches the stop block 242, it will be intercepted, causing the counting component 2 to stop counting when it counts to the number 0. A limiting flexible post 243 is provided on the outer edge support surface of the slot. The non-fixed end of the limiting flexible post 243 has a limiting protrusion 244. The limiting protrusion 244 has the same shape as the limiting recess 221 on the digital wheel 22. When not in use, the limiting protrusion 244 is always located in a limiting recess 221, which prevents the digital wheel 22 from being misaligned due to shaking or accidental falling. It also makes the rotation angle of the digital wheel 22 clearer and makes it easier for the digital wheel 22 to display the number. The upper part of the support surface is provided with a convex mirror 241, the position of which corresponds to the position of the display window 31. The structure of the convex mirror 241 can magnify the displayed numbers, which helps the user to see the numbers displayed on the number wheel 22 clearly.

[0050] like Figures 9-10 As shown, the aerosol bottle sleeve 21 is fixed to the aerosol bottle 1 by means of the snap finger 211. By simply adjusting the length of the snap finger 211, the counting component 2 can be adapted to any manufacturer's aerosol bottle 1. The top finger 212 on the aerosol bottle sleeve 21 will move up and down with the aerosol bottle 1. During the use of the overall drive, the aerosol bottle 1 is pressed down, causing the top finger 212 to gradually contact the ratchet 231 of the transmission wheel 23, and pushing the transmission wheel 23 to rotate clockwise. At this time, the curved surface of the ratchet 231 contacts the anti-reverse support arm 245, causing the anti-reverse support arm 245 to undergo flexible deformation, which can smoothly complete the clockwise rotation. After the device completes one counting action, the aerosol bottle 1, due to its internal elastic structure, will automatically reset to the initial state. At this time, the aerosol bottle sleeve 21 resets synchronously with the aerosol bottle 1.
