The invention aims to provide a practical cotton ball pen, which is used for ensuring that only one cotton ball is pushed out from a pen container every time and preventing waste of the cotton balls.
In order to achieve the purpose, the technical scheme of the invention is as follows: a practical cotton ball pen comprises a pen container, wherein a plurality of stacked disinfection units are arranged in the pen container, each disinfection unit comprises a fixed seat and a cotton ball with disinfectant, the cotton balls are fixed on the fixed seats, protective films wrap the cotton balls, a plurality of transverse grooves distributed along the axial direction of the pen container are arranged on the pen container, vertical grooves are connected among the transverse grooves, and push rods which are abutted against the disinfection units are connected on the transverse grooves and the vertical grooves in a sliding manner; the pen container is internally provided with a plurality of pressing mechanisms which are abutted against the side surfaces of the disinfection units, the front end of the pen container is provided with an outer expansion sleeve, the front end of the pen container is slidably connected with a sliding sleeve, the sliding sleeve is provided with an inner expansion sleeve for enabling the outer expansion sleeve to contract, and the inner wall of the outer expansion sleeve is provided with an inner cutter.
The working principle of the scheme is as follows: the pen container is used for containing a plurality of disinfection units. The fixing base is used for fixing the cotton balls. The sliding sleeve is used for driving the inner expansion sleeve to slide together. The internal expansion sleeve has an inward contracting tightening force. The outer expansion sleeve has an expansion force expanding outwards. When the outer expansion sleeve is sleeved by the inner expansion sleeve, the outer expansion sleeve is in a contraction state under the wrapping of the inner expansion sleeve, so that the front end of the pen container is sealed, external bacteria cannot enter the pen container, and the effect of protecting a disinfection unit in the pen container is achieved. In addition, the front end of the pen container is sealed by the inner expansion sleeve and the outer expansion sleeve, so that when the disinfection unit is pushed towards the direction close to the front end of the pen container, the disinfection unit at the front end of the pen container is blocked by the outer expansion sleeve, the plurality of disinfection units can be prevented from being pushed out of the pen container at one time, and the waste of the disinfection unit is prevented. The outer expansion sleeve shrinks under the wrapping of the inner expansion sleeve to form a cavity which can be used for accommodating cotton balls on the disinfection unit at the front end of the pen container. When the inner expansion tight sleeve slides towards the direction close to the tail end of the pen container, the outer expansion tight sleeve is separated from the package of the inner expansion tight sleeve, and the outer expansion tight sleeve is opened under the action of self expansion force, so that the front end of the pen container is automatically opened, the disinfection unit at the front end of the pen container is automatically exposed, and the disinfection unit at the front end of the pen container is convenient to use. The vertical groove is used for enabling the push rod to move axially along the pen container, and the push rod abuts against the disinfection unit, so that when the push rod moves towards the front end of the pen container along the vertical groove, the push rod pushes the disinfection unit in the pen container towards the direction close to the front end of the pen container, the disinfection unit in the pen container is convenient to sequentially close to the front end of the pen container, and sequential use of the disinfection unit in the pen container is achieved.

Thereby preventing a plurality of sterilizing units from being pushed out of the barrel to cause waste.
2. When the sliding sleeve slides towards the direction close to the tail end of the pen container, the sliding sleeve drives the inner expansion sleeve to be away from the outer expansion sleeve, the outer expansion sleeve is separated from the inner expansion sleeve and automatically opens under the action of self expansion force, and therefore cotton balls in the cavity of the outer expansion sleeve are exposed and convenient to use.
3. The inner wall of the outer expansion tight sleeve is provided with the inner cutter, the protective film on the cotton ball in the cavity of the outer expansion tight sleeve can be automatically scratched by the inner cutter, the protective film on the cotton ball is not required to be additionally torn manually, and the operation is simple and convenient.
4. The pressing mechanism is used for increasing the pressure and the friction force on the disinfection unit and preventing the disinfection unit from falling off from the pen container under the self gravity when the outer expansion tight sleeve is opened.
5. The transverse groove is used for abutting against the push rod, the push rod abuts against the disinfection unit, the push rod limits the disinfection unit, the disinfection unit is prevented from returning into the pen container due to the reaction force of wiping when cotton balls are wiped, and therefore normal use of the disinfection unit is guaranteed.
Furthermore, a sliding groove is formed in the pen container in the axial direction of the pen container, a sliding rod is arranged on the disinfection unit, and one end, far away from the disinfection unit, of the sliding rod penetrates through the sliding groove and is connected to the sliding groove in a sliding mode; the inner expansion sleeve intermittently offsets the sliding rod. When the disinfection unit is used up, the inner expansion sleeve is required to wrap the outer expansion sleeve, the inner expansion sleeve slides towards the direction of keeping away from the tail end of the pen container, the side part of the inner expansion sleeve, which is far away from the sliding sleeve, abuts against the sliding rod and pushes the sliding rod to slide in the sliding groove towards the direction of keeping away from the tail end of the pen container, and therefore the disinfection unit which is used up is pushed down from the pen container, automatic cleaning of the disinfection unit which is used up is achieved, the disinfection unit which is used up is not required to be manually pulled out, and the operation is simple and convenient. After the used disinfection unit falls off from the pen container, the outer expansion sleeve is wrapped by the inner expansion sleeve along with the continuous sliding of the inner expansion sleeve, so that the front end of the pen container is sealed.
Furthermore, the inner cutter is rotatably connected to the inner wall of the outer expansion sleeve, a torsional spring is arranged at the position where the inner cutter is rotatably connected with the outer expansion sleeve, the cutting edge of the inner cutter faces the cotton ball, the back of the inner cutter faces away from the cotton ball, the end part, away from the outer expansion sleeve, of the inner cutter is connected with an elastic rope, a rope hole is formed in the side wall of the front end of the pen container, and one end, away from the outer expansion sleeve, of the elastic rope penetrates through the rope hole and is connected to the sliding sleeve. When the sliding sleeve slides towards the direction close to the tail end of the pen container, the sliding sleeve pulls the inner cutter to rotate through the elastic rope, so that the cutting edge of the inner cutter faces towards the inner wall of the outer expansion sleeve. From this, the tight cover of outer bloated opens the back, and the cutting edge of interior cutter is towards the inner wall of the tight cover of outer bloated, and the back of a knife blade of interior cutter is towards the outside to when preventing to use the cotton ball, the cutting edge of interior cutter and skin contact are with people's fish tail. Because the elastic rope has elasticity, the elastic rope can freely extend, thereby being not limited by the sliding distance of the sliding sleeve. And the elastic rope generates elastic force after being stretched to be in a tight state, so that the inner cutter is pulled more tightly, and the inner cutter is more stable. When the sliding sleeve slides towards the direction close to the front end of the pen container, the elasticity on the elastic rope is reduced, and the torsional spring enables the inner cutter to reset.
Furthermore, a cutter groove for accommodating the inner cutter is arranged on the inner wall of the outer expansion sleeve. When the cutting edge of the inner cutter rotates to the inner wall of the outer expansion sleeve, the inner cutter enters the cutter groove, and therefore the space occupation of the inner cutter is reduced.
Furthermore, the pressing mechanism comprises a telescopic cylinder, a pressure spring and an extrusion block, the telescopic cylinder and the pressure spring are both connected between the extrusion block and the inner wall of the pen container, and the pressure spring is located in the telescopic cylinder. The extrusion block extrudes the disinfection unit under the action of the pressure spring, so that pressure and friction are applied to the disinfection unit. The telescopic cylinder is used for limiting the pressure spring, so that the pressure spring is prevented from being extruded and inclined.
Further, the one end of fixing base is equipped with first recess, and in the cotton ball was fixed in first recess, the other end of fixing base was equipped with the second recess that is used for holding the cotton ball on the adjacent disinfection unit.

As the cotton balls of the disinfection units are positioned in the second grooves on the adjacent disinfection unit fixing seats, the space occupation of the disinfection units in the cotton ball pens is reduced, more disinfection units can be arranged in the pen container, and the space utilization rate in the pen container is improved.
Furthermore, the inner wall of the sliding sleeve is provided with a rod groove and a rope groove which are axially arranged. Therefore, when the sliding sleeve slides on the pen container, the sliding rod on the disinfection unit slides in the rod groove, the elastic rope is located in the rope groove, and the sliding rod and the elastic rope cannot block the normal sliding of the sliding sleeve on the pen container.
Furthermore, the end part of the inner cutter, which is far away from the outer expansion sleeve, is provided with two rope holes, and the elastic rope is connected to the rope holes. From this, interior cutter receives the pulling of two stretch cords, and the atress is more even to the rotation that makes interior cutter is more stable.

Referring to fig. 8, the inner wall of the sliding sleeve 2 is provided with a rod-allowing groove 34 axially arranged, so that when the sliding sleeve 2 slides on the pen container 1, the sliding rod 10 is located in the rod-allowing groove 34, and the sliding rod 10 does not obstruct the sliding of the sliding sleeve 2 on the pen container 1. The inner wall of the outer expansion sleeve 5 is provided with an inner cutter 16. The inner cutter 16 is rotatably connected on the inner wall of the outer expansion sleeve 5 through a hinge, and a torsional spring is arranged at the position where the inner cutter 16 is rotatably connected with the outer expansion sleeve 5. The cutting edge of the inner cutter 16 faces the cotton ball 12, the back of the inner cutter 16 faces away from the cotton ball 12, as shown in the figure 7, the left end of the inner cutter 16 is rotatably connected with the outer expansion sleeve 5, the right end of the inner cutter 16 is provided with two rope holes, and the elastic ropes 15 are fastened on the rope holes. The front end of the pen container 1 is provided with a rope hole, and one end of the elastic rope 15, which is far away from the outer expansion sleeve 5, penetrates through the rope hole and is bonded on the sliding sleeve 2. As shown in fig. 8, the sliding sleeve 2 is further provided with two axially disposed rope grooves 33, so that the elastic rope 15 can pass through the rope grooves 33 to be bonded with the sliding sleeve 2, and the elastic rope 15 is prevented from affecting the normal sliding of the sliding sleeve 2. In addition, the inner wall of the outer expansion sleeve 5 is provided with a cutter groove for accommodating the inner cutter 16.
The specific implementation process is as follows: the stacked disinfection units are put into the pen container 1 through the tail end of the pen container 1, and one end of the push rod 7, which is positioned in the pen container 1, is abutted against the large-diameter end of the fixed seat 11 of the uppermost disinfection unit.
Referring to fig. 1, 2 and 4, since the outer expansion sleeve 5 is wrapped by the inner expansion sleeve 3, the outer expansion sleeve 5 is in a contracted state under the constraint of the inner expansion sleeve 3, the front end of the pen container 1 is sealed by the outer expansion sleeve 5 and the inner expansion sleeve 3, and a cavity is formed inside the outer expansion sleeve 5 when the outer expansion sleeve 5 is contracted. When the sterilizing pen container is used, the push rod 7 is pushed into the vertical groove 8, the push rod 7 is pushed downwards, and the push rod 7 drives all the sterilizing units to move towards the direction close to the front end of the pen container 1. Because the front end of the pen container 1 is sealed by the inner expansion sleeve 3 and the outer expansion sleeve 5, when the push rod 7 pushes the disinfection unit downwards, the disinfection unit cannot be pushed down from the pen container 1, and the cotton balls 12 on the lowest disinfection unit move into a cavity formed by the outer expansion sleeve 5. The cotton ball 12 on the lowest disinfection unit is pressed against the inner cutter 16 on the outer expansion sleeve 5, and the inner cutter 16 cuts the protective film on the cotton ball 12.
Referring to fig. 1, 3, 5 and 6, the push rod 7 is slid into the nearby transverse groove 6, the sliding sleeve 2 is slid towards the direction close to the tail end of the pen container 1, the sliding sleeve 2 drives the inner expansion sleeve 3 to slide away from the outer expansion sleeve 5, the outer expansion sleeve 5 is separated from the constraint of the inner expansion sleeve 3, and the outer expansion sleeve 5 automatically expands under the action of self expansion force, so that the cotton balls 12 in the outer expansion sleeve 5 are exposed and convenient to use.

After the pen container is used, the front end of the pen container 1 needs to be closed again. The sliding sleeve 2 is made to slide towards the direction far away from the tail end of the pen container 1, the side part of the inner expansion sleeve 3 far away from the sliding sleeve 2 is abutted against the sliding rod 10 on the sterilizing unit at the lowest part, the sliding rod 10 is pushed to slide towards the direction close to the front end of the pen container 1 in the sliding groove 9, the sliding rod 10 slides from the opening on the sliding groove 9, and therefore the used sterilizing unit is pushed out of the pen container 1. Along with the sliding sleeve 2 continues to slide to being close to the front end of the pen container 1, the inner expansion sleeve 3 continues to be in contact with the outer expansion sleeve 5, the inner expansion sleeve 3 wraps the outer expansion sleeve 5, and the outer expansion sleeve 5 is in a contraction state, so that the front end of the pen container 1 is closed. As the sliding sleeve 2 slides in the direction close to the outer expansion sleeve 5, the elastic rope 15 becomes loose, the inner cutter 16 rotates under the action of the torsion spring, and the inner cutter 16 resets to open, thereby being convenient for scratching the protective film on the cotton ball 12 next time.
Example 2
Example 2 differs from example 1 in that: the inner cutter 16 in the embodiment 2 is directly adhered to the inner wall of the outer expansion sleeve, and the inner cutter 16 cannot rotate on the outer expansion sleeve. Therefore, the structure of the outer expansion sleeve and the inner expansion sleeve is simplified, and the structures such as the elastic rope 15 and the torsional spring are omitted, so that the whole cotton ball pen is simpler in structure and has certain practicability.
