Detailed Description
In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the drawings of the embodiments of the present invention are combined below to clearly and completely describe the technical solution of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, a dosing pump with a counting function includes a threaded pipe 3;
specifically, the upper end of the threaded pipe 3 is connected with a push button 1, and the inner side of the push button 1 is provided with a plurality of actuating ribs 11;
a counting ring 2 is arranged in the upper end of the threaded pipe 3, a plurality of ratchets 23 and counting scales 24 are arranged on the outer side of the counting ring 2, and a plurality of matching ribs 21 are arranged on the inner side of the counting ring 2;
the inner side of the upper end of the threaded pipe 3 is provided with a ratchet wheel 31, and the ratchet wheel 31 is arranged corresponding to the plurality of ratchets 23; an observation hole 32 is formed on the threaded pipe 3, and the observation hole 32 is arranged corresponding to the counting scale 24; the counting ring 2 rotates along with the change of the pressed times, the corresponding counting scale 24 is corresponding to the observation hole 32, and the user can check the pressed times through the observation hole 32.
A pump core 5 is arranged in the threaded pipe 3, the upper end of the pump core 5 is connected with the push button 1, and the lower end of the pump core 5 is connected with a suction pipe 6; when the threaded pipe 3 is screwed on the bottle body 7, the suction pipe 6 extends into the bottle body 7 to suck the medicine in the bottle body 7.
Optionally, a gasket 4 is disposed at the position where the outside of the pump core 5 in the screw tube 3 contacts the bottle body 7, so that the inside of the bottle body 7 is sealed when the screw tube 3 covers the bottle body 7.
In some embodiments of the utility model, the side of actuating muscle 11 and the side of cooperation muscle 21 are the inclined plane, when pushing away to turn round 1 and receive the exogenic action downwardly movement, the inclined plane of actuating muscle 11 and the inclined plane of cooperation muscle 21 contact gradually to make counting ring 2 rotate.
Preferably, a matching groove 22 is formed between every two matching ribs 21, and the matching groove 22 is used for clamping the actuating rib 11, so that the push button 1 cannot move downwards continuously, and the counting ring 2 cannot rotate continuously.
In other embodiments of the present invention, a piston and a spring are arranged inside the pump core 5, the upper end of the piston is connected with the push button 1, and the lower end of the piston is connected with the spring; when the push button 1 moves downwards, the piston is driven to move downwards together, meanwhile, the spring is compressed, and when the force applied to the push button 1 disappears, the spring stretches to push the piston and the push button 1 to return to the initial position.
When the counting ring is used, the push button 1 is pressed downwards to move downwards, the inclined surface of the actuating rib 11 is gradually contacted with the inclined surface of the matching rib 21 in the process that the push button 1 moves downwards, the counting ring 2 is pushed to one side, and the counting ring 2 rotates. The push button 1 is continuously pressed until the actuating rib 11 is inserted into the matching groove 22, the push button 1 does not move downwards any more, and the counting ring 2 also stops rotating.
When the pressure on the push button 1 is released, the compressed spring begins to expand, and the push button 1 is driven to rise to the initial position. In the process, the actuator rib 11 is released from the engagement groove 22 along the original trajectory. After the actuating rib 11 is disengaged from the matching groove 22, the counting ring 2 can rotate, the plurality of ratchets 23 are matched with the ratchet wheel 31, the counting ring 2 continues to rotate for a certain angle until the ratchets 23 are meshed with the ratchet wheel 31, and the counting ring 2 stops rotating. The ratchet 23 is meshed with the ratchet wheel 31, so that the counting ring 2 can be prevented from rotating, and the counting ring 2 makes a sound to prompt a user to finish counting. At this time, the corresponding counting scale 24 is rotated to the viewing hole 32, and the user can look at the counting scale 24 through the viewing hole 32 to obtain the pressed number.
The utility model discloses a constant delivery pump with counting function, through promoting muscle and cooperation muscle, ratchet and ratchet cooperation realize the counting function of the number of times of pressing, and show the number of times of pressing in the form of count scale, facilitate the user to observe; and the push button and the pump core are designed into a whole, so that the loss of parts is avoided.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
