The utility model comprises a penholder, a decoration and a refill arranged at the lower part of the penholder. The decoration is placed on the visible part of the upper part of the penholder. A drive mechanism that drives the ornament to rotate.

Below in conjunction with accompanying drawing, the utility model is specifically described:

Embodiment one

As shown in Figure 1, the utility model comprises a penholder 2, a decoration 4 and a refill 3 arranged at the lower part of the penholder. , the cavity is provided with a drive mechanism 5 that drives the ornament 4 to rotate when the pen core 3 is pressed.

The driving mechanism 5 includes a touch switch 51 , a battery pack 52 and a motor 53 . The driving mechanism 5 can drive the decoration 4 to rotate when the pen core 3 is pressed. As shown in Figure 1, the pen refill 3 is arranged in the lower penholder 21, the nib 31 stretches out of the lower penholder 21, the inside of the upper penholder 22 is provided with a cavity 221, the driving mechanism seat 54 is screwed in the cavity 221, and the touch switch 51 , the battery pack 52 and the motor 53 are sequentially embedded in the drive mechanism seat 54, and form a control circuit (the circuit is shown in Figure 6). As shown in FIG. 3 , the driving mechanism seat 54 is provided with a battery cover 541 , a motor cover 542 and a bottom cover 543 . The battery cover 541 fixes the battery pack 53 on the drive mechanism seat 54 by screws, and the motor cover 542 fixes the motor 53 on the drive mechanism seat 54 by ultrasonic waves or glue. The end of the driving mechanism seat 54 close to the lower pen holder 21 is provided with a through hole 544 for allowing the tail end of the pen core 3 away from the pen tip 31 to pass through.

Of course, the drive mechanism seat 54 can also be eliminated, the touch switch 51, the battery pack 52 and the motor 53 are directly embedded in the cavity 221 of the pen holder 2, and the battery cover 541, the motor cover 542 and the bottom cover 543 are part of the cavity wall.

The touch switch 51 is disposed on the switch PCB 512 adjacent to the through hole 544 . As shown in FIG. 4 , the switch PCB 512 is provided with contacts respectively connected to the two poles of the control circuit, and a spherical shrapnel 513 that can deform along the moving direction of the pen core 3 . When the spherical shrapnel 513 is pressed against the two contacts on the switch PCB board 512, the touch switch 51 is closed, the control circuit is turned on, and the motor 53 works; when the spherical shrapnel 513 leaves the two contacts for reset, the touch switch 51 is off. Open, the control loop is disconnected.

When the pen core 3 is moved under pressure, its tail end can pass through the through hole 544 to press the spherical shrapnel 513, so that the touch switch 51 is closed and the control circuit is turned on. However, if the moving direction of the pen core 3 deviates under this structure, it is difficult to trigger the control loop through the through hole 544 . Therefore, in order to ensure accurate transfer of the pen core 3 under pressure, a touch button 511 can be embedded in the through hole 544 . The length of the touch button 511 protruding from the drive mechanism seat 54 through the through hole 544 is greater than the distance between it and the spherical shrapnel 513 . When the refill 3 is moved under pressure, the trigger button 511 is pushed to move in the through hole 544, and presses the spherical shrapnel 513 so that it deforms to contact with the contacts and conducts the control circuit.

The positional relationship between the touch switch 51, the battery pack 52 and the motor 53 is not unique, it is only necessary to ensure that a control loop is formed between them, the touch switch 51 can be closed due to the pressure movement of the pen core 3, and the motor 53 can be closed in the loop When driving the ornament 4 times to rotate and get final product.

The working process of this embodiment: the pen tip 31 is pressed when writing, the pen core 3 moves upward relative to the pen holder 2, drives the touch button 511 to move up, presses down the spherical shrapnel 513, the touch switch 51 is closed, and the entire control circuit is turned on. The motor 53 works to drive the decoration 4 or the rotor 532 and the decoration 4 thereon to rotate. When the writing is stopped, the force on the nib 31 disappears, the pen core 3 returns, the spherical crown shrapnel 513 rebounds and resets, the touch switch 51 is disconnected, the whole control circuit is disconnected, the motor 53 stops working, and the ornament 4 stops rotating.

The battery pack 52 supplies power to the motor 53, and the outer magnetic steel 533 rotates accordingly. Under the action of the magnetic force, the inner magnetic steel 534 in the sealed transparent tube 6 drives the rotor 532 to rotate in the same direction, and the rotor 532 drives the liquid decoration 4 on the transparent tube 6. Internal rotation. When the writing stops, the force on the nib 31 disappears, and the rotation stops.

In order to strengthen the ornamental effect when the liquid ornament 4 rotates, the ornament 4 can be a colored liquid, or a liquid of different specific gravity, and a suspended object (such as a doll) can also be placed in the liquid, and the suspended object will rotate and stop with the liquid And up and down in the liquid.

Embodiment three

The battery pack 52 supplies power to the motor 53. Under the action of the oscillating circuit, the motor 53 drives the outer magnet 533 to rotate intermittently. Under the action of the magnetic force, the inner magnet 534 in the sealed transparent tube 6 rotates intermittently in the same direction, and the liquid decoration The object 4 rotates intermittently in the transparent tube 6 , especially when there is a suspended object placed in the liquid ornament 4 , the suspended object will go up and down with the intermittent rotation of the liquid ornament 4 , which is very dynamic. When the nib 31 is continuously stressed for a long time, if there is no oscillation circuit, the liquid decoration 4 will rotate monotonously in one direction, but in this embodiment, the liquid decoration 4 will rotate up and then stop falling, and then reciprocate and suspend The object will rise and fall, or tumble in the liquid. Writing stops nib 31 stressed and disappears, and rotation stops.
