Detailed ways

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.

Please refer to FIG. 1 and FIG. 2, the embodiments of the present invention include:

An aerosol dispenser push button with a counter, comprising: a push button 1, a cap body 2, a counter and a counter housing 7, the cap body 2 is arranged at the bottom end of the push button 1, and the counter is arranged at the push button 1. At the outer side wall of the button 1, the counter housing 7 is arranged on the outer side of the counter for fixing the counter on the outer side wall of the push button 1;

The counter includes: a counter base 3, a gear 4, a one-digit disc 5, and a ten-digit disc 6. The counter base 3 is snapped on the outer side wall of the push button 1, and the side wall of the push button 1 is provided with a plurality of installations. Hole 14, a plurality of mounting posts 35 are arranged on the side of the counter base 3 close to the push button 1. The positions and dimensions of the mounting posts 35 match the mounting holes 14. When installing, insert the counter base 3 into the hole 14. It is arranged in the installation hole 14 of the side wall of the push button. A fixed shaft 13 is arranged at the outer side wall of the push button 1, the units plate 5 is sleeved on the outer side of the fixed shaft 13, and the ten plate 6 is sleeved and pressed on the units plate 5, as shown in FIG. 4 . , a step 64 is provided at the bottom wall of the ten-place plate, so that after the one-place plate 5 is pressed into the ten-place plate 6, it will not drop from the middle hole of the ten-place plate 6, and the ten-place plate 6 is arranged at a distance away from the pusher. On one side of the side wall of the button 1, the diameter of the tens disc 6 is larger than that of the ones disc 5, and the tens disc 6 and the ones disc 5 are coaxially arranged.

As shown in FIG. 3 , a ratchet wheel 51 is provided on the side of the units dial 5 , and a coaxial units dial gear 52 is arranged in the units dial ratchet 51 . As shown in FIG. 4 , in the tens position The side of the disk 6 is provided with a tens disk ratchet 61 , and a coaxial ten disk gear 62 is arranged in the ten disk ratchet 61 ; the ones disk 5 is sleeved in the gear of the ten disk 6 .

2, the counter base 3 includes: a cantilever beam 36, an actuating rod 31 under the cantilever beam 36, a connecting arm 37 connecting the cantilever beam 36 and the actuating rod 31, and the end of the actuating rod 31 has an outward Protruding end, one end of the cantilever beam 36 is connected to the counter base 3, the other end of the cantilever beam 36 is suspended, and an actuating pawl 32 is provided at the cantilever beam at the suspended end, and the actuating pawl The end of 32 is inclined outward and protrudes into the ratchet wheel 51 of the unit plate. When the user presses the aluminum can (not shown in the figure), the aluminum can has downward pressure on the end of the actuating rod 31, and the actuating rod When the 31 moves downward, it can drive the actuating pawl 32 to move downward, so that when the actuating pawl 32 moves downward, it drives the units disc ratchet 51 to rotate one unit position to complete one count; there are guiding ribs inside the push button. (not shown in the figure), in cooperation with the guide buckle 38 of the actuating rod, it has a guiding effect on the actuating rod 31 of the counter base, so that the actuating rod 31 can only move up and down.

The outer side wall of the push button 1 is provided with a gear shaft hole 12 , the gear shaft 41 of the gear 4 is inserted into the gear shaft hole 12 , the gear 4 and the one-place plate gear 5 and the ten-place plate gear 6 are respectively mesh. The number of teeth of the units disc gear 5 is two, and the two teeth are arranged at 180 degrees. When the units wheel ratchet 51 rotates to 180, one tooth of the ones wheel gear 5 can drive the gear 4 to rotate by one tooth, correspondingly, the gear 4 drives the tens wheel gear 62 to rotate one tooth, thereby completing the ten wheel 6 once. count.

Further, a counter housing 7 is provided on the outer side of the counter base 3, the counter housing 7 is clamped on the side wall of the push button 1, and a plurality of shell bayonets are opened at the side wall of the push button. 11. A casing buckle 72 is correspondingly provided on the side of the counter casing 7 close to the push button. The position and size of the casing bayonet 11 match the casing buckle 72 . During installation, the casing buckle 72 can be snapped into the casing bayonet 11 .

In conjunction with Fig. 2, Fig. 5 and Fig. 6, the counter base 3 is also provided with a position plate anti-rotation pawl 33 and a ten-place plate anti-rotation pawl 34, and the end of the one-place plate anti-rotation pawl 33 is provided. The ends of the anti-rotation pawls 34 of the ten-place plate and the ten-place plate are inclined outward, and respectively extend into the ones-place plate ratchet wheel 51 and the ten-place plate ratchet wheel 61 . Since each wheel disc of the ratchet wheel is inclined at a certain angle, both the ones disc ratchet wheel 51 and the tens disc ratchet wheel 61 can only rotate in one direction and cannot rotate. Specifically, in the initial state, the end of the anti-rotation pawl 33 of the one-place disc and the end of the anti-rotation pawl 34 of the ten-place disc are both located at the lowest part of the ratchet wheel disc. Only when the ratchet wheel rotates in the set direction, the pawl can Movement from low to high. Once reversed, the pawl cannot cross the highest point of the ratchet wheel disc. Due to the interference effect of the units disc anti-rotation pawl 33 and the ten disc anti-rotation pawl 34, the ratchet cannot rotate, thus preventing the rotation.

In the present invention, a display window 71 is provided at the counter housing 7 , and a transparent cover plate 8 is provided at the display window 71 . The transparent cover plate 8 adopts a convex lens. In the initial use state, the display window 71 displays an initial value, and the user can see the value of the counter more clearly through the convex lens. A section of shielding plate 63 is provided at the tooth end of the ten-position disc gear 6 . At the shielding plate 63, the ten disc gear 6 does not have the number of teeth, and the gear 4 cannot drive the ten disc gear 6 to rotate, that is, when the counter reaches the shielding plate 63, the liquid medicine in the device is used up. In order to facilitate the user's observation, the shielding plate 63 can be painted in a relatively obvious color such as red, and finally displayed through the display window 71 . The shielding plate 63 will completely cover the counter display window 71 and prompt the user with a clear color that the medicinal solution has been used up and the user can discard the device.

The above descriptions are only the embodiments of the present invention, and are not intended to limit the scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied to other related technologies Fields are similarly included in the scope of patent protection of the present invention.
