[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0029] WITH REFERENCE TO Figure 1 , Figure 2 An embodiment provided by the utility model: a ship cabin air purification device, including shell 1, the top right side of shell 1 is fixedly connected with air inlet pipe 2, the bottom left side of shell 1 is fixedly connected with air outlet pipe 3, the inside of shell 1 is provided with dust falling mechanism, air enters the inside of shell 1 from air inlet pipe 2, then moves from right to left from shell 1, is preliminarily handled by dust falling mechanism, so that the dust of relatively large particles contained in air first settles down, then fine dust particles are filtered by cloth bag dust collector 16, can reduce the burden of cloth bag dust collector 16, increase the workable duration of cloth bag dust collector 16, avoid the filtration effect of cloth bag dust collector 16 from being reduced due to being quickly blocked by large-particle dust, reduce the frequency of cloth bag dust collector 16 needing to be cleaned.

[0030] WITH REFERENCE TO Figure 2 , Figure 3The dust suppression mechanism includes a fixed block 4 and a protrusion 8. The fixed block 4 is fixedly installed on the inner wall of the housing 1. A baffle 5 is hinged to the inner wall of the fixed block 4. A baffle 6 is hinged to the end of the baffle 5 away from the fixed block 4. Both the baffle 5 and the baffle 6 are set in an inclined state, forming a V-shape. The lengths of the baffles 5 and 6 are equal. The total number of baffles 5 and 6 is set to two sets, which are respectively set on the upper and lower sides of the housing 1 and at different heights. This makes the airflow path roughly Z-shaped when the air flows inside the housing 1, which can block larger dust particles in the air and make them settle down under the action of gravity. A movable block 7 is hinged to the end of the baffle 6 away from the baffle 5.

[0031] Reference Figure 2 , Figure 3 The protrusion 8 is fixedly installed on the inner wall of the housing 1, and the movable block 7 is slidably installed on the outer wall of the protrusion 8. The sliding direction of the movable block 7 is left and right. The protrusion 8 is set as a dovetail block, and the movable block 7 is provided with a dovetail groove inside. The protrusion 8 is slidably installed inside the dovetail groove. In this way, when the protrusion 8 slides inside the dovetail groove, the movable block 7 can be prevented from falling off the surface of the protrusion 8, thus improving the stability of the displacement. The movable block 7 is provided with a positioning mechanism inside.

[0032] Reference Figure 3 The positioning mechanism includes a limiting block 9 with a rectangular cross-section. The limiting block 9 is slidably mounted on the inner wall of the moving block 7. The limiting block 9 is elastically connected to the inner wall of the moving block 7 by a spring 11. The spring 11 applies a spring force to the limiting block 9 in the direction close to the wedge 10. The positioning mechanism also includes a wedge 10, which is fixedly mounted on the side of the limiting block 9 away from the spring 11. The surface of the protrusion 8 is provided with a limiting groove 12 that cooperates with the wedge 10. The cross-section of the wedge 10 is triangular. The number of limiting grooves 12 is set to multiple. The multiple limiting grooves 12 are arranged in a straight line at equal intervals on the surface of the protrusion 8. By setting multiple limiting grooves 12, the moving block 7 drives the wedge 10 to move inside the multiple limiting grooves 12, which plays the role of multi-level adjustment of the stop position of the moving block 7.

[0033] Reference Figure 2 A threaded rod 14 is horizontally mounted through and rotatably installed on the inner wall of the housing 1. The surface of the threaded rod 14 is threadedly connected to the inner wall of the moving block 7. A knob 13 is fixedly connected to the right side of the threaded rod 14. When the threaded rod 14 rotates, the moving block 7 is moved linearly left and right through the threaded conversion. A filter mechanism is provided inside the housing 1. The filter mechanism includes a vertical plate 15, which is fixedly installed on the inner wall of the housing 1. The vertical plate 15 is located between the filter mechanism and the dust collection mechanism. A bag filter 16 is fixedly connected to the left side of the vertical plate 15. The outer wall of the bag filter 16 is in contact with the inner wall of the housing 1.

[0034] Working principle: in use, gas from the intake pipe 2 into the housing 1 inside, the air in the housing 1 is roughly from right to left movement, and by the blocking of the baffle one 5 and baffle two 6, the flow of air will and the surface of the inclined baffle two 6 collision, so that the air larger particles of dust movement energy loss, so as to settle down, the remaining smaller particles of dust follow the gas via cloth bag dust collector 16 purification after discharge to the atmosphere, reduce environmental pollution, while effectively protecting the operating personnel near the equipment.

[0035] By rotating the knob 13 drive screw rod 14 rotation, so that the moving block 7 left and right displacement, moving block 7 displacement makes the baffle two 6 slope changes, by changing the two sets of baffle two 6 slope, so that the air flow path in the housing 1 is roughly formed a Z shape, thereby increasing the path length of air flow, and improve the probability of dust and baffle two 6 impact in the air, improve the accuracy of dust control strength.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application have, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
