Description of the new model: [Technical field to which the new model belongs] This creation relates to a positive pressure dust box, especially a fan that continuously blows the inside of the box for a long time to prevent dust or debris from accumulating from the holes and entering the box. : On the lens, the positive pressure dustproof box that prolongs the use time of the lens in the box has a simple structure, low cost and easy assembly, and is suitable for use in various laser engraving machines. [Previous technology] Laser cutting and engraving processing technology is currently a rapidly developing and widely used trendy processing technology, which has wide applicability and high processing precision; does not damage the workpiece, and is easy to control and reliable, and has high processing efficiency. , Good engraving quality and other advantages. The design of the laser engraving machine on the market today is provided next to the laser tube — it ’s equipped with a lens holder so that the laser light can be produced by the system on the lens holder. Of course, when the vibration of the test is continued, the dust on the lens surface of the bin or the Qur'an holes will accumulate on the surface of the lens, which will cause the user to touch the segment and turn it. _ Carved: The lens is clean, so it is very tedious and time consuming. Nowadays, the industry has accumulated on the lens in order to overcome the two holes.乂 Avoid dust from self-holes. However, although this method can overcome the accumulation of dust in the box, it is often necessary to connect it before each engraving operation. However, the structure is complex, bulky, and costly. For solving the aforementioned problems, it seems to be inconsistent with economic efficiency. Lai Ji, if only in view of this, the creator has been continually studying the dust box to solve the problem of the existing technology street. X Yi ,,, < Developed a positive M271643 [New content] The main purpose of this creation is to provide-difficult cakes and equipment, simple, low, low, easy, and can prevent dust from entering the box. The positive pressure dust box that accumulates on the lens and prolongs the use time of the lens. Disc 1: For the purpose of I and I, the dustproof box set in this creation includes a box body fan. There is at least one lens holder in the chamber for the lenses to be placed on each side of the box body. An air inlet and an air outlet are respectively provided, and the fan is combined with the air inlet on the side of the rotor body, so that the air outside the box is sucked into the box by the fan, and then discharged through the air outlet to reduce Accumulation of dust on the lens. _ In order to facilitate a deeper understanding of this creation, Lai—the examples are detailed later: [Implementation] Complete: Tea reading Figures 1 and 2 'The content of the diagram is the positive pressure dust box 1 of the creation-Implementation 1 , /, Is composed of a box body 11 and a fan 12. For example), the body 11 is L-shaped. There are lens holders 111 (three are used in this embodiment, and earthworms 112 are respectively placed on it. The top of the box body 11 is provided with an air outlet 114. Inside, For side II, there is an air inlet 113 'on the side for air circulation in the box body 11'. The fan 12 is for connecting to the above-mentioned air inlet 113 on the side of the button u. After the air outside the body 11 is continuously sucked into the box body 11 through the fan 12, the air holes m are exhausted to prevent dust from entering through the air outlet holes 114 and accumulating on the mirror-side ^ day ^ Please refer to Figures 2 ~ 4. The fan 12 is combined with the box body, and the mouth box 113 is parallel to the box body 11 and the laser tube 2 of the laser machine. The i seat = the laser light emitted by the tube 2 can pass through the positive pressure dust box. The lens m on the river within 1 is refracted, and at the same time, the fan 12 is turned on, and the M271643 12 is pumped into the box 11 and the dust or debris outside the body u is discharged from the air outlet n4 due to the air outlet 114. The wind pressure ... can enter the box 11 from the air outlet 114 and accumulate on the lens 112. In addition, as shown in Figures 2 and 4, to prevent dust outside the box u from passing through the fan box / inside It can be at the level of the fan 12 with a filter material or filter cloth cotton ~ consideration thereof) to effectively cut off from the outer dust cassette n. Therefore, 'using the aforementioned design, it is possible to effectively avoid the design of combining the volume of each box directly with a ^ fan ^ hybrid n, without the need for external equipment, ie, early reading, early assembly and disassembly are convenient, and it can effectively reduce production The cost is in line with the economic benefits. One . . In summary, this creation can indeed achieve the intended purpose of the creation, providing a positive pressure box that is early, easy to assemble or disassemble, and low in cost. It is extremely expensive. Mai made a new patent application according to law. ， Used knowledge, [Schematic description] Figure 1 is a three-dimensional appearance of the creative embodiment. Figure 2 is a three-dimensional view of the reality. ❿ Figure 3 is the three-dimensional appearance of the creative embodiment combined with the laser tube. FIG. 4 is a schematic diagram of the internal air flow after the fan is started in the creative embodiment.
