The debris on the π-shaped block 1 is sucked into the collection cavity 3 through the chip removal assembly 5. Collect it to prevent debris from entering the children's nasal cavity by mistake.
[0027] The chip removal assembly 5 includes an induced draft fan 6 and a chip removal plate 7. The induced draft fan 6 is provided with multiple and fixed on the inner wall of the collection chamber 3. A mounting groove 8 is opened on the top of the collection chamber 3, and the installation groove 8 is A driving member 10 is fixed. The bottom of the driving member 10 is fixed with the chip plate 7. The collection chamber 3 has a discharge port 11 at the bottom, and a closing door 12 is provided in the discharge port 11, which is generated by the rotation of the induced draft fan 7 Negative pressure suction, adsorption of debris, while sweeping debris through the debris removal plate 6;
[0028] The driving member 10 includes a driving motor 13, a moving block 14, and an electric push rod 15. The driving motor 13 is installed and fixed on the inner wall of one end of the installation slot 8 away from the induced draft fan 6, and the output end of the driving motor 13 is fixed with a screw rod 16. One end of the screw rod 16 away from the drive motor 13 is rotatably connected to the inner wall of the mounting groove 8 through a bearing. Two sliding rods 17 are provided on the outside of the screw rod 16, and both ends of the sliding rod 17 are fixed to the inner wall of the mounting groove 8 respectively. 14 is sleeved on the outside of the sliding rod 17, and is threadedly connected with the screw rod 16, and is fixed to the top of the chip plate 7 through the electric push rod 15. The driving motor 13 rotates to drive the screw rod 16 to rotate, so that the moving block 14 is in the mounting groove Move within 8 to drive chip removal board 7 to remove chips;
[0029] At the same time, the front end of the air inlet of the induced draft fan 6 is provided with a barrier 18, which prevents debris from being adsorbed on the induced draft fan 6 to reduce wind power. The bottom of the barrier 18 is in contact with the inner wall of the collection chamber 3, and an air suction port 19 is left at the top. .
[0030] The closed door 12 includes a mounting plate 20, a door plate 21, and a latch 22. The two ends of the door plate 21 are connected to the mounting plate 20 through a pin shaft, and the mounting plate 20 is fixed to the bottom of the π-shaped block 1, and the door plate 21 is far away from the mounting plate 20. A socket 23 is opened at one end, and the outside of the socket pin 22 is slidably connected with the inner wall of the socket 23. Both ends of the socket pin 22 are provided with a limit plate 24, and the socket pin 22 is inserted into the limit plate 24, and the material is discharged by the switch of the door panel 21 Opening and closing of mouth 11.
[0031] A shaking groove 25 is opened in the feeding channel 4, and a shaking plate 26 is rotatably connected to the shaking groove 25. A tension spring 27 is fixed at the bottom of the shaking plate 26 and contacts the inner wall of the shaking groove 25 through the tension spring 27. A rotating port 28 is opened in the rotating port 28, and a shaker 29 is installed in the rotating port 28, and the shaker 29 is used to drive the rotation of the shaker plate 26, so as to realize the rapid discharge of the debris in the feeding channel 4;
[0032] The shaking member 29 includes a shaking motor 30 and a cam 9. The shaking motor 30 is installed in the rotation port 28, and the output end of the shaking motor 30 is fixed to the cam 9, and the cam 9 is in contact with the bottom of the shaking plate 26 and is rotated by the shaking motor 30 The cam 9 is driven to rotate, so as to realize the shaking of the shaking plate 26.
[0033] Specific implementation method: When in use, place the π-type block 1 in front of the child. Since the π-type block 1 is made of environmentally friendly plastic, there is no pollution hazard and will not affect the children’s health. When the child tears paper on the π-type block 1 and plays At this time, it is inevitable that debris caused by tearing paper will remain on the π-shaped block 1. At this time, the induced draft fan 6 is rotated to generate negative pressure suction in the collection chamber 3, so that the debris on the π-shaped block 1 passes through the feeding channel 4 Into the collection chamber 3, when a certain amount of debris is collected, the drive motor 13 is rotated and the electric push rod 15 is lowered, so that the debris removal plate 7 sweeps the debris in the collection chamber 3, and then manually pull out the latch 22 and open The door panel 21 realizes the opening of the discharge port 11 to discharge the debris, which effectively prevents some small paper debris from being stored on the π-shaped block 1 and being sucked into the nasal cavity by children by mistake, and at the same time collecting waste paper plays an environmental protection role.
[0034] In this solution, the drive motor 13 is preferably Y80M1-2, the induced draft fan 6 is preferably LH-200, the shaking motor 30 is preferably Y80M2-2, and the electric push rod 15 is preferably ANT-35. The power supply interface of the motor is connected to the power supply system through a switch The motor operation circuit is a conventional motor forward and reverse rotation control program, and the circuit operation is an existing conventional circuit. The circuits and controls involved in the present invention are all existing technologies, which will not be repeated here.
[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply one of these entities or operations. There is any such actual relationship or order between. Moreover, the terms "include", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes those that are not explicitly listed Other elements of, or also include elements inherent to this process, method, article or equipment.
[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
