[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a laser marking machine protective dust suction device for absorbing particulate matter generated during the marking process of the laser marking machine 1, comprising a shell 2, wherein the shell 2 is arranged on one side of the laser marking machine 1; the filter layer 3 is arranged inside the shell 2, and the shell 2 is divided into a first cavity 201 and a second cavity 202, wherein the first cavity 201 has a first air inlet 2011 and a first air outlet 2012, and the first air outlet 2012 is connected to a negative pressure device; the air inlet pipe 4 is arranged in the shell 2, one end of which extends out of the first air inlet 2011, and the other end is located in the second cavity 202; the dust hood 5 is arranged outside the lens of the laser marking machine 1, and the dust hood 5 is connected to one end of the air inlet pipe 4.

[0037] In this embodiment, the laser marking machine 1 generates particulate matter when it is working, and the negative pressure device is started to generate negative pressure inside the housing 2, so that the particulate matter is sucked into the air inlet pipe 4 through the dust hood 5, and then enters the second cavity 202. The particulate matter in the second cavity 202 is sucked into the first cavity 201 by the negative pressure device, and then passes through the filter layer 3 to achieve the effect of filtering the particulate matter. The advantage is that the particulate matter generated during the production process of the laser marking machine 1 can be filtered in time, so as to prevent the operator from inhaling the air containing the particulate matter for a long time, thereby affecting the respiratory tract and causing symptoms such as respiratory irritation and allergies.

[0038] Furthermore, it also includes an air pump 6, which is a negative pressure device. The air pump 6 is arranged on the housing 2 and is connected to the first air outlet 2012.

[0039] In this embodiment, the negative pressure device is an air suction pump 6, which has the advantage that the air suction pump 6 can perfectly realize the air suction function required by the dust suction device.

[0040] Furthermore, the second cavity 202 has a first liquid inlet 2021 and a first liquid outlet 2022 . The second cavity 202 is used to contain liquid, and one end of the air inlet pipe 4 is below the liquid level.

[0041] In this embodiment, a first liquid inlet 2021 and a first liquid outlet 2022 are additionally provided in the second cavity 202, and filtered liquid is injected into the second cavity 202. One end of the air inlet pipe 4 located in the second cavity 202 is lower than the horizontal plane of the filtered liquid, so that the gas containing particulate matter entering from the air inlet pipe 4 first enters the filtered liquid for the first water filtration, and the gas after water filtration is then filtered for the second time through the filter layer 3. The advantage is that the particulate matter in the air can be filtered more thoroughly.

[0042] Furthermore, the housing 2 has first grooves 203 on both sides, and the filter layer 3 is split and slidably disposed in the first grooves 203 on both sides.

[0043] In this embodiment, first grooves 203 are added on both sides of the housing 2, and the split filter layer 3 can be slidably installed and removed in the first grooves 203, respectively. The advantage is that the filter layer 3 can be replaced and cleaned more quickly.

[0044] Furthermore, the inner diameter of the second cavity 202 gradually decreases toward the first liquid outlet 2022 .

[0045] In this embodiment, the inner diameter of the second cavity 202 gradually decreases toward the first liquid outlet 2022. The advantage is that the particles filtered by the liquid in the second cavity 202 will slide toward the first liquid outlet 2022 along the slope generated by the gradual decrease in the inner diameter, and finally gather at the first liquid outlet 2022, thereby preventing the particles filtered by the liquid from accumulating in the corners of the second cavity 202, causing inconvenience in cleaning.

[0046] Furthermore, the second cavity 202 has a second liquid inlet 204, which is connected to a water source, and also includes a first valve body 7, one end of which is connected to the first liquid outlet 2022; one end of the filter cartridge 8 is connected to the other end of the first valve body 7; the filter screen 9 is arranged in the filter cartridge 8; the other end of the filter cartridge 8 is connected to one end of the circulating water pump 10, and the other end of the circulating water pump 10 is connected to the first liquid inlet 2021.

[0047] In this embodiment, a first valve body 7 is added to the first liquid outlet 2022, and the first valve body 7 is used to control the filtered liquid in the second cavity 202 to flow out from the first liquid outlet 2022. A filter cartridge 8 is provided at the first liquid inlet 2021, and a filter net 9 is provided in the filter cartridge 8. There are particulate matter in the filtered liquid flowing out of the first liquid outlet 2022. After filtering through the filter net 9, the particulate matter in the filtered liquid is filtered. The other end of the filter cartridge 8 is connected to a circulating water pump 10, and the filtered liquid is re-injected into the second cavity 202 after filtering, so as to recycle the filtered liquid. At the same time, a second liquid inlet 204 is added to the second cavity 202 for injecting new filtered liquid.

[0048] Furthermore, the dust hood 5 is transparent.

[0049] In this embodiment, the dust cover 5 will be made of transparent material, and this material can also reduce the damage caused by laser to human eyes, skin and other tissues.

[0050] Furthermore, the second cavity 202 is transparent, and the filter cartridge 8 is transparent.

[0051] In this embodiment, the second cavity 202 is made of transparent material, which has the advantage that the remaining amount and status of the filtered liquid in the second cavity 202 can be accurately observed, and the filtered liquid can be replenished and replaced in time. The filter cartridge 8 is made of transparent material, which has the advantage that the condition of the filter net 9 can be accurately observed, facilitating timely replacement of the filter net 9.

[0052] Furthermore, both ends of the filter cartridge 8 have chamfers 801 .

[0053] In this embodiment, the benefit of having the chamfer 801 is to prevent particles in the filtered liquid from accumulating at the connection between the filter cartridge 8 and the first valve body 7 .

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
