[0030] The following is a detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings.

[0031] like Figures 1 to 9As shown, a chalk eraser cleaning device includes an outer shell 1 and a vibration component 2, a dust collection box 3 and a fan 4 installed inside the outer shell 1; by installing the chalk eraser on the vibration component 2 inside the outer shell 1, and then driving the vibration component 2 to move, the chalk eraser vibrates away the chalk dust under the action of the vibration component 2, at this time, the fan 4 is started and the interior of the outer shell 1 is changed to a negative pressure state, so that the chalk dust can better fall into the dust collection box 3. After cleaning the chalk dust on the chalk eraser, it is only necessary to take out the chalk eraser and clean the chalk dust in the dust collection box 3.

[0032] The device is used to clean the chalk dust on the chalk eraser. Since manual cleaning is not required, it can greatly prevent the chalk dust emitted from the chalk eraser from being inhaled into the human body when cleaning the chalk eraser, thereby ensuring the health and safety of everyone. In addition, the device can better utilize fragmented time to clean the chalk dust on the chalk eraser, which is more convenient.

[0033] The specific structures of the device are as follows.

[0034] like Figures 1 to 3 and Figure 7 As shown, the interior of the above-mentioned outer shell 1 is provided with a cavity 11, and a partition layer 18 for upper and lower stratification is provided in the cavity 11, and a perforation 19 is provided on the partition layer 18, and a storage groove 12 (for placing the dust storage box 3) connected to the cavity 11 is provided on one side of the outer shell 1, and a cover plate 13 is provided on the top of the outer shell 1, and an opening 14 is provided on the cover plate 13; wherein a plurality of air outlets 15 are provided on the bottom of the outer shell 1, and the setting of the air outlet 15 can be coordinated with the fan 4 (the air outlet direction of the fan 4 is toward the bottom of the outer shell 1), so that when the fan 4 is started, the wind will be blown from the air outlet 15 to the outside of the outer shell 1, thereby forming a negative pressure in the cavity 11, so as to better allow the vibrated chalk dust to fall into the dust storage box 3.

[0035] like Figure 3 As shown, due to the above-mentioned reasons for the formation of negative pressure, the cavity 11 at the bottom of the outer shell 1 is set as a negative pressure cavity 20. The shape of the negative pressure cavity 20 and the bottom of the outer shell 1 are both inverted trapezoidal shapes, and the negative pressure cavity 20 is located below the fan 4, and several of the above-mentioned air outlets 15 are evenly distributed on the inclined surface of the inverted trapezoid.

[0036] In order to better ensure the operation of the device, support feet 6 distributed at the four corners are provided at the bottom of the device to support the outer shell 1, so that the inverted trapezoidal part of the bottom of the outer shell 1 does not directly contact the ground / plane.

[0037] like Figures 1 to 6 as well as Figure 9As shown, the vibration assembly 2 is arranged on the cover plate 13, and the entire vibration assembly 2 includes a vibration motor 21, a transmission rod 22 and a chalk eraser fixing member 23.
