DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing device has a poor effect on the treatment of paint particles. Excessive paint particles attached to the fan are not convenient for workers to clean, which reduces work efficiency.

[0021] In view of this, an external ventilation device for spraying building formwork is provided. Through the cooperation between the square shell, the activated carbon bag and the cover plate, the filtration of paint particles and the absorption of odors are achieved, and the treatment effect is improved. The user only needs to clean the filter, which solves the problem that the existing device has a poor treatment effect on paint particles, and too many paint particles attached to the fan are not convenient for staff to clean, thereby reducing work efficiency.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1-3 It can be seen that an external ventilation device for spraying building templates includes a fan 1 and a spray gun 9. The spray gun 9 can spray paint on the template for protection. An air inlet pipe 2 and an air outlet pipe 3 are respectively installed on both sides of the fan 1. The model of the fan 1 is not limited. A processing mechanism is arranged on the outside of the fan 1. The processing mechanism includes a square shell 4, a mesh plate 11, an activated carbon bag 12, a branch pipe 5, an outer shell 6 and a filter screen 16. The top of the square shell 4 is connected to one end of the air outlet pipe 3. Two mesh plates 11 are fixedly connected to the inner side of the square shell 4. The inner side of the two mesh plates 11 is provided with an activated carbon bag 12. The activated carbon bag 12 can absorb odors. The bottom of the square shell 4 is connected to the outer shell 6 through the branch pipe 5. The inner side of the outer shell 6 is movably connected to the filter screen 16.

[0024] In the specific implementation process, it is worth pointing out that the cooperation between the branch pipe 5, the housing 6 and the filter 16 realizes the filtration of paint particles and the absorption of odor, thereby improving the treatment effect. The user only needs to clean the filter 16, which solves the problem that the existing device has a poor treatment effect on paint particles, and too many paint particles attached to the fan 1 are not convenient for the staff to clean, thereby reducing the work efficiency.

[0025] Furthermore, a cover plate 13 is movably connected to a through hole on one side of the square shell 4. The cover plate 13 can move in the through hole on one side of the square shell 4. Both sides of the cover plate 13 are fixedly connected to the outer side of the square shell 4 by bolts 14.

[0026] In the specific implementation process, it is worth pointing out that the user can remove the bolt 14 and remove the cover plate 13 to replace the internal activated carbon bag 12;

[0027] Furthermore, a moving mechanism 8 is fixedly connected to the back of the spray gun 9, and a template positioning mechanism 10 is provided below the moving mechanism 8 and the spray gun 9;

[0028] In the specific implementation process, it is worth pointing out that the moving mechanism 8 can drive the spray gun 9 to move horizontally, thereby realizing spraying at different positions of the template, and the template positioning mechanism 10 is used to place and fix the template;

[0029] Specifically, when using the external ventilation device for spraying building templates, the user can first start the fan 1. When working, the fan 1 sucks in the mixture of air and paint particles under the outer shell 6, and filters it through the filter 16, and then enters the square shell 4. The activated carbon bag 12 inside the square shell 4 can absorb the odor, and finally transport it to the outside of the factory through the fan 1.

[0030] Embodiment 2: By Figure 1 , 2 As can be seen from Figures 4, a baffle 15 is attached to the top of the filter 16, one side of the baffle 15 is fixedly connected to the inner side of the housing 6, a rotating plate 19 is attached to the bottom of the filter 16, a block 20 is attached to the top of the rotating plate 19, one side of the block 20 is fixedly connected to the outer side of the housing 6, the inner side of the block 20 is rotatably connected to a rod 21 fixed to the top of the rotating plate 19 through a bearing, the rod 21 can rotate through the bearing, and the outer side of the rod 21 is movably connected to a spring 7, and the two ends of the spring 7 are respectively fixedly connected to the top of the rod 21 and the top of the block 20;

[0031] In the specific implementation process, it is worth pointing out that the device can drive the rotating plate 19 to fit under the filter screen 16 to limit the position by relying on the elastic deformation of the spring 7, and at the same time, the baffle 15 located above can limit the upper part of the filter screen 16, thereby ensuring the stability of the filter screen 16;

[0032] Furthermore, a square plate 17 is attached to the bottom of the filter screen 16, and a bracket 18 is installed at the bottom of the square plate 17;

[0033] In the specific implementation process, it is worth pointing out that the square plate 17 can shield the filter 16, and the user can shield the filter 16 according to the length of the sprayed template;

[0034] Specifically, on the basis of the above-mentioned first embodiment, the filter screen 16 can be quickly disassembled through the cooperation between the spring 7, the baffle 15 and the rotating plate 19, which is convenient for the user to remove and clean, thus saving operation time.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" 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 includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0036] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
