However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0035] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.

[0037] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0038] Referring to Figures 1 and 2, in one embodiment of the present application, a counting mechanism 100 is provided for counting the number of atomizations of an inhalation device, and includes a housing 10 and a counting assembly 20. The housing 10 includes a shell and a magnifying glass 40. The shell has a visual window 12, and the magnifying glass 40 is mounted on the visual window 12. The counting assembly 20 is disposed within the shell and is used to form different counts at the visual window 12. The counting mechanism 100 can be used in an inhalation device that atomizes an aerosol-generating substrate. Each time the inhalation device is used, the counting assembly 20 can count once to display the number of atomizations completed or the number of remaining atomizations, so that the user can clearly know the usage of the medicine and replace the liquid storage bottle or the inhalation device in a timely manner.

[0039] In addition, a magnifying glass 40 is provided at the visual window 12 where the counting mechanism 100 displays the count. The count formed by the counting component 20 can be magnified by the magnifying glass 40, and the count can be clearly displayed. At the same time, the counting mechanism 100 does not need to be set to a larger volume to mark larger numbers, saving the internal space of the shell.

[0040] In some embodiments, the magnifying glass 40 has a magnification factor of 2-3 times. For example, if the height and width of the characters on the counter assembly 20 are 2.3 mm and 2.5 mm, respectively, the height and width of the characters after magnification are 6.0 mm and 6.5 mm, respectively. Alternatively, the magnification factor is 2.5 times. Furthermore, the magnifying glass 40 may be made of PC, have a lens thickness of 2.5 mm, and have an object distance of 1.5 mm from the characters.

[0041] In some embodiments, the magnifying glass 40 may be a convex lens or a Fresnel lens.

[0042] Referring to Figures 1-4 , in some embodiments, the counting assembly 20 includes a first drive disk 22 and a first counting disk 24, both rotatably mounted on the housing. Each time the first drive disk 22 rotates, the first counting disk 24 follows the rotation of the first drive disk 22, and the count changes. In other words, each use of the inhaler device causes the first drive disk 22 to rotate once, which in turn causes the first counting disk to count once, thereby counting the number of uses of the inhaler device.

[0043] Furthermore, the first counter disc 24 has a plurality of numbers spaced along its circumference on the side facing the magnifying glass 40. As the first counter disc 24 rotates, any number can be moved to the visible window 12 in the magnifying glass 40, thereby forming a count. In other words, the first counter disc 24 has multiple numbers marked on the side facing the magnifying glass 40. As the first counter disc 24 rotates, different numbers can be moved to the visible window 12 in the magnifying glass 40, thereby displaying the count in the visible window 12 and clearly displaying it after being magnified by the magnifying glass 40.

[0044] In some embodiments, when the first counting disk 24 rotates to the limit position, the first counting disk 24 abuts against the housing limit position. That is, when the count reaches the limit value, the first counting disk 24 is restricted to the limit position and no longer rotates, and no further counting is performed. For example, the numbers marked on the first counting disk 24 are 0-30, and the counting mechanism 100 is used to display the remaining number of atomizations. The count displayed in the initial state is 30. When the count gradually decreases to 0, the position between 0-30 on the first counting disk 24 rotates to the visual window 12, indicating that the remaining number of atomizations is zero and the inhalation device cannot be used further. The first counting disk 24 is also restricted to the limit position and cannot be rotated, thereby effectively reminding the user.

[0045] Furthermore, a reminder mark 241 is provided on the first counting disk 24. When the first counting disk 24 rotates to the extreme position, the reminder mark 241 rotates to the visual window 12. For example, the reminder mark 241 is set between 0 and 30. When the count gradually decreases from 30 to 0, the reminder mark 241 rotates to the visual window 12 to remind the user that the remaining number of atomizations is zero and the inhalation device cannot be used any further.

[0046] Optionally, a first protrusion 14 is provided on the shell, and a second protrusion 243 is provided on the first counting disk 24. When the first counting disk 24 rotates to the limit position, the first protrusion 14 and the second protrusion 243 abut against each other, limiting the first counting disk 24 at the limit position to prevent the first counting disk 24 from continuing to rotate.

[0047] 5-6 , in some embodiments, the counting assembly 20 includes a second drive disk 30, a second counting disk 50, and a third counting disk 70. The second drive disk 30, the second counting disk 50, and the third counting disk 70 are all rotatably mounted on the housing 10. The second counting disk 50 is in driving connection with the second drive disk 30, and the third counting disk 70 is in driving connection with the second counting disk 50. Each time the second drive disk 30 rotates, the second counting disk 50 follows the rotation of the second drive disk 30 and changes the number displayed on the disk. The third counting disk 70 changes the number displayed only when the second counting disk 50 rotates to a predetermined position. The number displayed on the second counting disk 50 and the number displayed on the third counting disk 70 combine to form a count.

[0048] Above-mentioned counting mechanism 100 can be used for the inhalation device of atomized aerosol generation matrix, and the inhalation device can drive the second drive disk 30 to rotate once every use, and then the second counting disk 50 and the third counting disk 70 are followed by the rotation of the second drive disk 30 and follow-up, and the number combination on the second counting disk 50 and the third counting disk 70 is utilized to form a count. Specifically, the inhalation device atomizes once, and drives the second counting disk 50 to rotate once to change the number, and then counts once. The inhalation device atomization process usually needs the actuation of its internal drive mechanism (not shown) to complete, and its internal drive mechanism mechanical coupling is connected to the second drive disk 30, and synchronously drives the second drive disk 30 to actuate in the drive mechanism actuation process, and completes the process of administration and counting simultaneously.

[0049] Moreover, the third counting disk 70 only moves once with the atomizing body together with the second counting disk 50 when the second counting disk 50 rotates to the preset position, and a number change occurs. This is equivalent to the third counting disk 70 moving once when the number counted by the second counting disk 50 reaches ten and increments by one, so that the number can be counted to ten. In this way, the number on the second counting disk 50 and the number on the third counting disk 70 are combined to form a count, indicating the number of times atomization has been completed or the remaining number of atomizations, so that the user can clearly know the usage of the medicine and replace the new liquid storage bottle or the new inhalation device in time.

[0050] Furthermore, the second counting disc 50 has a hollow hole 51, and the third counting disc 70 is eccentrically mounted within the hollow hole 51. Any number on the third counting disc 70 and any number on the second counting disc 50 are rotated until they are adjacent to each other and combined to form a count. Thus, by eccentrically mounting the third counting disc 70 within the hollow hole 51 of the second counting disc 50, any number on the third counting disc 70 and any number on the second counting disc 50 can be combined adjacent to each other to form a count.

[0051] In some embodiments, the number change on the second counting disk 50 is a change in the units digit, and the number change on the third counting disk 70 is a change in the tens digit. In this way, through the cooperation between the second counting disk 50 and the third counting disk 70, different numbers on the second counting disk 50 and different numbers on the third counting disk 70 are counted in combination, and the number of atomizations that can be counted can reach tens digits.

[0052] Specifically, the second counter disk 50 rotates through a first predetermined angle to cause a digit change, and the third counter disk 70 rotates through a second predetermined angle to cause a digit change. That is, for the second counter disk 50 that changes the units digit, a full rotation is divided into ten parts. The numbers on the second counter disk 50 are 0-9, and the digits change every 36 degrees (the first predetermined angle), for example, from 0 to 9, from 9 to 8, and so on.

[0053] In addition, the numbers on the third counting disk 70 can be 0-3, 0-6, etc., which are not limited here. Moreover, the number 0 on the third counting disk 70 can be replaced by other markings, such as a red mark, to issue a striking reminder when the remaining liquid amount becomes zero.

[0054] 6-7 and 9 , in some embodiments, the second counting disk 50 includes a second disk body 52 and a ring gear 54 . A plurality of numbers are set on the second disk body 52 . The ring gear 54 is provided on the second disk body 52 and is in transmission connection with the second drive disk 30 . In this way, through the transmission connection between the ring gear 54 and the second drive disk 30 , the second drive disk 30 drives the second disk body 52 to follow the rotation, thereby causing the numbers used for counting on the second disk body 52 to change.

[0055] Furthermore, transmission teeth 541 are arranged circumferentially on the inner circumference of the ring gear 54, and the second drive disc 30 is sleeved in the ring gear 54 and meshes with the transmission teeth 541 for transmission. In this way, sleeved inside the ring gear 54, the second drive disc 30 is saved in the installation space and can realize the transmission connection between the two.

[0056] In some embodiments, the counting mechanism 100 further includes a transmission gear 80, which is transmission-connected between the ring gear 54 and the third counting disk 70. The third counting disk 70 only follows the second counting disk 50 when it rotates to a preset position and undergoes a digital change. In this way, the transmission gear 80 is utilized to transmission-connect the second counting disk 50 and the third counting disk 70, so that the third counting disk 70 rotates once when the second counting disk 50 rotates to a preset position.

[0057] Furthermore, the outer circumference of the ring gear 54 is provided with incomplete teeth 543. The incomplete teeth 543 mesh with the transmission gear 80 only when the second counting disk 50 rotates to a preset position. The incomplete teeth 543 are provided on the outer circumference of the ring gear 54 in the second counting disk 50. It can be understood that the incomplete teeth 543 are incomplete on the outer circumference of the ring gear 54, for example, only one tooth or multiple teeth. In this way, during the rotation of the second counting disk 50, the incomplete teeth 543 intermittently mesh with the transmission gear 80, thereby causing the third counting disk 70 to perform intermittent motion driven by the transmission gear 80. The second ring gear 54 does not need to constantly rotate with the first ring gear 54. It is sufficient for the second ring gear 54 to achieve a digital change when the first ring gear 54 rotates to a preset position.

[0058] Specifically, in this embodiment, the counting mechanism 100 is used to display the remaining number of uses. The numbers on the second counting disk 50 include numbers from 0 to 9. When the number 0 is used to form a count, the second counting disk 50 is in a preset position, the incomplete teeth 543 engage with the transmission gear 80, and the transmission gear 80 then drives the third counting disk 70 to rotate once. For the counting mechanism 100 that displays the remaining number of atomizations, when the numbers on the second counting disk 50 gradually decrease from 9 to 0, the decrement of the tens digit has been completed. The third counting disk 70 needs to make a digital jump to cause the tens digit to decrement once, thereby realizing the gradual decrement of the count.

[0059] For example, when the remaining number of times changes from 30 to 29, the 0 in the second counter disk 50 is used for counting, the second counter disk 50 is in the preset position, and the number on the second counter disk 50 is decremented from 0 to 9. Simultaneously, the number on the third counter disk 70 is decremented from 3 to 2, i.e., both the ones and tens digits are decremented. For another example, when the remaining number of times changes from 29 to 28, the second counter disk 50 is not in the preset position. Only the number on the second counter disk 50 is decremented from 9 to 8, and the number on the third counter disk 70 does not change.

[0060] It is understood that in some other embodiments, the counting mechanism 100 is used to display the number of times the inhalation device has been used, and the numbers on the second counting disk 50 include numbers from 0 to 9. When the number 9 is used to form a count, the second counting disk 50 is in a preset position, the incomplete teeth 543 engage with the transmission gear 80, and the transmission gear 80 drives the third counting disk 70 to rotate once. Equivalently, for the counting mechanism 100 that displays the number of times the inhalation device has been used, when the numbers on the second counting disk 50 gradually increase from 0 to 9, the tens digit has already been incremented, and the third counting disk 70 needs to perform a digit jump to cause the tens digit to carry once, thereby achieving a gradual count increase.

[0061] In some embodiments, a first limit member 60 is provided on the housing 10, and each time the second counting disk 50 changes its number, it is limited and blocked by the first limit member 60. In this way, each time the second counting disk 50 rotates once, it is limited and blocked by the first limit member 60 to prevent the second counting disk 50 from rotating excessively, thereby ensuring the accuracy of each number change.

[0062] Furthermore, at least some of the tooth grooves in the transmission teeth 541 are configured as first limiting grooves 521. The first limiting portion abuts against any one of the plurality of first limiting grooves 521 in the rotational direction of the second counter disk 50. Thus, each time the second counter disk 50 rotates, the first limiting member 60 abuts against a different first limiting groove 521. The cooperation between the first limiting member 60 and the first limiting groove 521 provides a stop for each numerical change of the second counter disk 50, preventing the second counter disk 50 from excessive rotation.

[0063] 6 and 8-9 , in some embodiments, a second stopper 90 is provided on the housing 10. Each time the third counter disk 70 changes its number, the second stopper 90 stops it. Thus, each time the third counter disk 70 rotates, the second stopper 90 stops it, preventing it from over-rotating and ensuring the accuracy of each number change.

[0064] Furthermore, the third counter disk 70 includes a third disk body 72 and a gear portion 74. A plurality of numbers are provided on the third disk body 72. The gear portion 74 is disposed on the third disk body 72 and meshes with a transmission gear 80. The meshing transmission between the gear portion 74 and the transmission gear 80 drives the third counter disk 70 to rotate with it. At least some of the teeth in the gear portion 74 are configured as second limiting grooves 741, and a plurality of second limiting grooves 741 are provided corresponding to the numbers on the third disk body 72. In other words, at least some of the plurality of teeth on the outer periphery of the gear portion 74 function as second limiting grooves 741 for abutting against the second limiting portion.

[0065] Furthermore, during the rotation of the third counter disk 70, the second stopper 90 engages with any one of the plurality of stopper grooves in the rotational direction of the third counter disk 70. Thus, each time the third counter disk 70 rotates, the second stopper 90 engages with a different second stopper groove 741. The cooperation between the second stopper 90 and the second stopper groove 741 provides a stop for each digit change in the third counter disk 70, preventing the third counter disk 70 from excessive rotation.

[0066] Specifically, for the gear part 74, a plurality of tooth grooves are distributed on the outer periphery of the gear part 74, some of the plurality of tooth grooves are used to engage with the transmission gear 80, and one of the other part of the plurality of tooth grooves is used to abut the second limit member 90, so that the second limit portion and the transmission gear 80 are staggered. For example, the second limit portion and the transmission gear 80 are arranged on opposite sides of the gear part 74. The second limit portion will not affect the normal engagement of the transmission gear 80 and the gear part 74, and can also perform limit blocking every time the number changes.

[0067] It is understood that the "numbers" in the above embodiments can be numerals in any language, such as Arabic numerals, Roman numerals, English numerals, Chinese numerals, etc. The counting rule format can also be any existing counting rule format, such as decimal, binary, duodecimal, etc. In other embodiments, the "numbers" can also be user-defined marking symbols, and the counting rule can also be a user-defined counting rule.

[0068] In one embodiment of the present invention, an inhalation device is provided, comprising an atomizing body and a counting mechanism 100 as described in any of the above embodiments. The atomizing body is used to atomize the aerosol-generating substrate, and the counting mechanism 100 changes each time the atomizing body performs atomization. Specifically, each time the atomizing body performs atomization, the counting component 20 changes, and the counting mechanism 100 displays the number of times used or the number of times remaining. This allows the user to accurately know the number of atomizations used, facilitating the timely replacement of a new liquid storage bottle or a new inhalation device.

[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
