Excessive dust indirectly harms employee health and increases the risk of occupational diseases. Furthermore, the high temperature of the silicon material causes employees to sweat profusely; the evaporation and dripping of sweat contaminate the silicon material, affecting product quality.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0030] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0032] Example:
[0033] See Figure 1 and Figure 2 This embodiment discloses a dust removal and cooling protection device for spilled materials, including a cover 10, a dust removal component 20, and a control component 30. The sides, top, and back of the cover 10 are all enclosed, and a connecting part 40 is installed at the bottom of the cover 10. The connecting part 40 includes multiple downward-facing quick-connect interfaces, through which the entire device can be quickly installed in the working area.
[0034] A dust removal component 20 is provided on the top of the cover 10, and a control component 30 is provided on the side of the cover 10. Specifically, the control component 30 is electrically connected to the dust removal component 20, and the control component 30 controls the start and stop of the dust removal component 20, and provides power to the dust removal component 20.
[0035] In this embodiment, by designing a cover 10, the cover 10 is installed at the work point, and then the dust removal component 20 on the cover 10 is controlled by the control component 30 to work, thereby protecting the work point.
[0036] Through this technical solution, the cover 10 directly avoids the splashing of silicon material when the carbon head is struck, and the dust removal component 20 can directly clean the dust in the work area and indirectly reduce the temperature of the work point through the flow of air, thereby reducing the risk of occupational diseases and improving product quality.
[0037] In one specific embodiment:
[0038] Multiple mounting holes 11 are installed on the top surface of the cover 10, and the dust removal assembly 20 is installed on all the mounting holes 11. When the dust removal assembly 20 is working, dust and airflow flow out of the cover 10 through the mounting holes 11, thereby achieving the purpose of cleaning the dust inside the cover 10 and refreshing the air inside the cover 10.
[0039] In another specific embodiment:
[0040] The dust removal assembly 20 includes a fan 21 and a filter bag 22. Specifically, a fan 21 is provided on each mounting hole 11. All fans 21 are electrically connected to the control assembly 30, and the control assembly 30 directly controls all fans 21 to start and stop synchronously.
[0041] Once the fan 21 is installed and started, the airflow passing through the fan 21 flows from inside the shroud 10 to outside the shroud 10. During the operation of the fan 21, it drives the gas inside the shroud 10 to flow to the outside, thereby carrying away the dust inside the shroud 10.
[0042] In addition, a cloth bag 22 is provided at the position of each mounting hole 11. The opening of the cloth bag 22 completely covers the air outlet of the fan 21, and the cloth bag 22 is detachably connected to the cover 10.
[0043] By setting up a cloth bag 22, the dust extracted by the fan 21 can be collected. The detachable connection between the cloth bag 22 and the cover 10 facilitates dust cleaning.
[0044] In another specific embodiment:
[0045] The control component 30 includes a mounting box 31, a battery 32, and a button 33. The mounting box 31 is fixedly mounted on the side of the cover 10, with its opening facing upwards. The battery 32 is inserted into the mounting box 31 through its opening. After being inserted into the mounting box 31, the battery 32 is electrically connected to the fan 21 of the dust removal component 20. Generally, a wiring harness is provided between the dust removal component 20 and the control component 30 to achieve power transmission.
[0046] In addition, button 33 is mounted on mounting box 31 and is located on the wiring harness between battery 32 and dust removal assembly 20, so that the start and stop of dust removal assembly 20 (mainly controlling the start and stop of fan 21) can be achieved by simply pressing button 33.
[0047] Preferably, a light source can also be provided on the top of the cover 10 to provide sufficient light for the employee's work area.
[0048] In this embodiment, by designing an independent power supply for the battery 32, the need to run power strip cables in the workshop is avoided, and the convenience of the device is fully utilized, making it unrestricted by the power supply. By designing the battery 32 as pluggable, the problem of the battery 32 being unusable when its power is insufficient can be solved.
[0049] In another specific embodiment:
[0050] It is understandable that, since the battery 32 is a quick-connect plug-in type in the mounting box 31, multiple power supply contacts are generally provided on the outer surface of the battery 32, and multiple connection contacts are provided in the mounting box 31. Power is supplied through the contact between the connection contacts and the power supply contacts.
[0051] When arranging the wiring, button 33 should be installed between the connecting contact point and the dust removal component 20.
[0052] In another specific embodiment:
[0053] The connecting part 40 includes two U-shaped grooves, which are arranged parallel to each other and have an inverted structure to form a quick-connect interface. The quick-connect interface allows for quick installation in the working area.
[0054] Preferably, the two U-shaped grooves are respectively located at the bottom of both sides of the cover 10.
[0055] In another specific embodiment:
[0056] An inclined mounting portion is provided at the connection between the cover 10 and the back, and the dust removal assembly 20 is mounted on the mounting portion. With this design, the fan 21 can draw airflow in an inclined direction, thereby enabling the fan 21 to remove dust and gas from a larger area.
[0057] The above-described embodiments merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
