[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0041] The words expressing positions and directions described in this utility model are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of this utility model.

[0042] This utility model discloses a counting and locking device, which is used to count the number of times of use of an atomizer and lock it to limit its use after the counting is completed. Refer to Figures 1 to 5 As shown, the counting and locking device includes an upper housing 1, a main rotating body 2, a shrapnel 3 and a counting component 4.

[0043] As Figure 2 shown, a clamping groove 11 is provided on the inner wall of the upper housing 1. The clamping groove 11 can be located in the bottom area of the upper housing 1 and is continuous in the circumferential direction, so as to form a rotational fit with the protrusion 22 on the main rotating body 2.

[0044] In addition, a recess 12 is provided on the clamping groove 11. The recess 12 is located above the clamping groove 11 and is used to cooperate with the shrapnel 3 to achieve the locking function. In this application, the number of recesses 12 is preferably 2, and they are distributed on both sides of the inner wall of the upper housing 1 at 180°.

[0045] As Figures 2 to 4 shown, the main rotating body 2 is cylindrical and part of it is arranged inside the upper housing 1. A through groove 21 is provided on the part of the main rotating body 2 that coincides with the upper housing 1. The through groove 21 extends to the upper end face of the main rotating body 2 to facilitate product molding (the forming difficulty and cost of the through type structure are relatively low).

[0046] A protrusion 22 is also provided on the part of the main rotating body 2 that coincides with the upper housing 1. The protrusion 22 is similar to a bridge structure and spans outside the through groove 21 to form a hollow area therewith for compressing the shrapnel 3. In addition, the protrusion 22 is also assembled with a groove to achieve the anti-disengagement function. In this application, the protrusion 22 can be continuous or spaced in the circumferential direction. For example, the number of protrusions 22 is preferably 2, and they are distributed on both sides of the outer wall of the main rotating body 2 at 180° to improve the stability of the rotational connection between the upper housing 1 and the main rotating body 2.

[0047] As Figure 3 and Figure 4As shown, the elastic piece 3 is arranged in the straight-through groove 21 and is pressed and limited by the protrusion 22. In this application, the elastic piece 3 is generally U-shaped. The elastic piece 3 includes a straight section 31 located in the straight-through groove 21, a clamping section 33 located inside the protrusion 22, and a connecting section 32 connecting the straight section 31 and the clamping section 33. In the initial state, the protrusion 22 presses the clamping section 33 against the hollow area, and at the same time, the connecting section 32 deforms to accumulate elastic force.

[0048] As Figure 1 and Figure 3 shown, the counting component 4 is arranged on the outer wall of the main rotating body 2. The counting component 4 includes a push arm 41 that can move along the axial direction of the device. The push arm 41 moves towards the elastic piece 3 as the number of counts increases.

[0049] In the above counting and locking device, each time the upper housing 1 rotates one circle, the counting component 4 only realizes one counting function, so as to achieve the effect of doubling the count. For details, see the following description. And when the counting function fails, the push arm 41 can push the elastic piece 3 out from the inside of the protrusion 22, causing part of the elastic piece 3 to actively snap into the recess 12. Specifically, as Figure 5 shown, after the push arm 41 moves the clamping section 33 out from the inside of the protrusion 22, the connecting section 32 and the clamping section 33 are no longer under the pressing action. Under the action of elasticity, the clamping section 33 unfolds and snaps into the recess 12, thereby restricting the relative rotation of the upper housing 1 and the main rotating body 2.

[0050] See Figure 3 and Figure 4 shown, in some embodiments, an opening 311 is provided on the straight section 31, and the straight section 31 extends towards the counting component 4 to form a bending portion 312. A limiting block 5 is arranged in the straight-through groove 21, and a stop block 6 is arranged on the side of the limiting block 5 close to the counting component 4. Among them, the limiting block 5 passes through the opening 311 and cooperates with the stop block 6 to hold the bending portion 312, thereby fixing the elastic piece 3 in the straight-through groove 21, so as to improve the installation stability of the elastic piece 3.

[0051] It is worth mentioning that the bending portion 312 has a certain ability of deformation and guiding. When contacting the stop block 6, it guides the installation of the elastic piece 3 and enhances the interference with the stop block 6 through slight deformation, so as to ensure the installation effect.

[0052] In some embodiments, an assembly hole 321 is provided on the connecting section 32. The assembly hole 321 is used to cooperate with a manipulator to realize an automatic assembly function. In this application, the assembly hole 321 is preferably arranged in the center to ensure the balance of the transfer of the elastic piece 3.

[0053] Still as Figure 3As shown, in some embodiments, a stop surface 51 and a curved surface 52 are respectively provided on one side of the limiting block 5 facing the stop block 6. The stop surface 51 and the curved surface 52 are connected in sequence from inside to outside. Among them, the stop surface 51 is used to limit the axial movement of the elastic piece 3, and the curved surface 52 is used to guide the elastic piece 3 to jump over the limiting block 5. In this application, the thickness dimension of the stop surface 51 is less than or equal to the thickness dimension of the straight section 31, and the radius dimension of the curved surface 52 is greater than the thickness dimension of the stop surface 51, which enables the elastic piece 3 to smoothly jump over the limiting block 5 with the assistance of the push arm 41, thereby enabling the locking function.

[0054] Participate Figure 1 As shown, in some embodiments, the front end of the push arm 41 has a lifting surface 411 that fits with the bending portion 312, which is used to lift the bending portion 312 out of the straight-through groove 21, so that it is separated from the limiting block 5. In this application, the lifting surface 411 is integrally formed on the inclined surface at the front end of the push arm 41, and its included angle is approximately between 10° and 30°, so as to be inserted between the bending portion 312 and the straight-through groove 21.

[0055] Refer to Figure 1 And Figure 3 As shown, in some embodiments, the counting component 4 can provide a counting function of at least 120 times to meet the requirements of a certain dose or multiple actuation counting. Specifically, the counting component 4 further includes a screw 42 and a slider 43. Among them, the screw 42 is rotatably arranged on the outer wall of the main rotating body 2, a triggering unit 44 is arranged at one end of the screw 42 close to the upper shell 1, the slider 43 is threadedly connected to the screw 42, an indicating member 45 is arranged on one side of the slider 43, and the other side is connected to the push arm 41.

[0056] Correspondingly, a tooth groove 13 that cooperates with the actuating unit is also provided on the inner wall of the upper shell 1. In the prior art, the number of tooth grooves 13 is two, which are distributed on both sides of the inner wall of the upper shell 1 at 180°. This enables the upper shell 1 to drive the screw 42 to rotate half a turn every half turn, and prompts the atomizer to release a dose once, while the indicating member 45 counts once. However, in this application, the number of tooth grooves 13 is only one, which enables the upper shell 1 to drive the screw 42 to rotate half a turn every full turn, but this process prompts the atomizer to release two doses, while the indicating member 45 only counts once. That is to say, without modifying the counting component 4, by reducing the number of tooth grooves 13, the counting component 4 can be used for more doses or more actuation counting, thereby reducing the modification cost and increasing the scope of application.

[0057] It can be understood that in some other embodiments, the above functions can also be achieved by changing the thread density of the screw 42 or the length of the screw 42, etc.

[0058] Refer to Figure 3 And Figure 5As shown, in some embodiments, the triggering unit 44 includes a first triggering portion 441 and a second triggering portion 442 that are vertically crossed. The first triggering portion 441 and the second triggering portion 442 can be integrally formed at the upper end of the screw 42, and the length of the first triggering portion 441 is greater than the length of the second triggering portion 442. Among them, the first triggering portion 441 is used to engage with the tooth groove 13. Specifically, every time the upper housing 1 rotates one circle, the tooth groove 13 has a chance to contact the first triggering portion 441 once, thereby driving the screw 42 to rotate 180° and count once. The second triggering portion 442 is used to abut against the inner wall of the upper housing 1 to increase the transmission stability between the triggering unit 44 and the screw 42, but the second triggering portion 442 does not contact the tooth groove 13 to avoid interfering with the transmission between the tooth groove 13 and the first triggering portion 441.

[0059] See Figure 1 、 Figure 3 and Figure 4 As shown, in some embodiments, a first mounting portion 23 and a second mounting portion 24 are sequentially arranged on the outer wall of the main rotor 2 along the axial direction of the device. Exemplarily, the first mounting portion 23 can be a shaft hole seat, and the second mounting portion 24 can be a C-shaped clamping seat. The screw 42 is rotatably connected to the first mounting portion 23 and the second mounting portion 24 respectively, and this design is conducive to the quick loading and unloading of the screw 42.

[0060] In addition, a limiting ring 421 is arranged on the screw 42 close to the second mounting portion 24 to limit its own axial movement. On the one hand, it can prevent affecting the transmission between the tooth groove 13 and the triggering unit 44. On the other hand, it can avoid the push arm 41 triggering the elastic piece 3 in advance and affecting the use of the device.

[0061] The present utility model also discloses an atomizer, including the above-mentioned counting and locking device, so as to count the number of times the atomizer is used and lock it to limit its use after the counting is completed.

[0062] Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be construed as a limitation to the present utility model. Without departing from the principle and purpose of the present utility model, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the utility model, and all these changes should fall within the protection scope of the claims of the present utility model.
