Description

Technical Field

[0001] This utility model relates to the field of hot air blower technology, specifically a marine hot air blower with dehumidification function. Background Technology

[0002] In the marine environment, due to prolonged exposure to high humidity and harsh weather conditions, maintaining dry and clean air inside the cabins is crucial for ensuring the health of the crew and the proper functioning of equipment. While traditional marine hot air blowers can provide heating, they have certain limitations in dehumidification and air purification.

[0003] Traditional hot air blowers primarily focus on heating, lacking effective dehumidification and air purification capabilities. In humid environments, simple heating cannot effectively reduce the moisture content in the air, potentially leading to excessively high humidity in the cabin, affecting crew comfort and accelerating equipment corrosion. Traditional hot air blowers are typically equipped with simple filtration devices that can only remove larger particles, failing to effectively filter fine particles, odors, and harmful gases.

[0004] Therefore, this utility model provides a marine hot air blower with dehumidification function. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a marine hot air blower with dehumidification function, thus solving the aforementioned problems.

[0012] Beneficial effects

[0013] This invention provides a marine hot air blower with dehumidification function. Compared with the prior art, it has the following advantages:

[0014] (1) This marine hot air blower with dehumidification function first filters air through a mesh screen to intercept large particles, then through a filter cartridge for secondary filtration. The filtered air then passes through a silica gel desiccant filter plate for efficient moisture adsorption, followed by an activated carbon desiccant filter plate for further moisture absorption, while also adsorbing odors and harmful gases. The treated air is then heated by the blower body and discharged, providing dry and warm air. Through multi-stage filtration and moisture absorption, the purity and comfort of the air are significantly improved, reducing the impact of pollutants and moisture in the air on the health of the crew.

[0015] (2) This marine hot air blower with dehumidification function can start the motor when a lot of dust accumulates on the surface of the filter cartridge, driving the gear to rotate and the annular plate to rotate, thereby driving the cleaning plate to clean the surface of the filter cartridge, effectively removing the dust and impurities attached to the surface of the filter cartridge and maintaining the filter cartridge in a high-efficiency working state. The cleaned dust and other impurities fall into the collection frame at the bottom of the collection cartridge, and the collection cartridge can be removed periodically to clean the impurities. The operation is simple and convenient. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-3 A marine hot air blower with dehumidification function includes a hot air blower body 1. An air inlet pipe 11 is fixedly connected to one side of the hot air blower body 1. A connecting pipe 2 is fixedly connected to the bottom of the air inlet pipe 11 by bolts. A filter assembly is provided inside the connecting pipe 2. A collection cylinder 4 is screwed to the lower part of the connecting pipe 2. The filter assembly includes a mounting plate 31 fixedly connected to the middle of the inner wall of the connecting pipe 2. A filter cylinder 32 is fixedly connected to the mounting plate 31 by bolts. A first fixing plate 33 is fixedly connected to the inner wall of the connecting pipe 2 above the filter cylinder 32. A silica gel desiccant filter plate 34 is fixedly connected to the first fixing plate 33 by bolts. A second fixing plate 35 is fixedly connected to the inner wall of the connecting pipe 2 above the silica gel desiccant filter plate 34. An activated carbon desiccant filter plate 36 is fixedly connected to the second fixing plate 35 by bolts.

[0024] Specifically, the bottom of the collecting cylinder 4 is provided with an annular groove, and a mesh plate 41 is fixedly installed in the annular groove; the top of the connecting pipe 2 is fixedly connected with a connecting strip 12, and the bottom of the air inlet pipe 11 is provided with a connecting groove for the connecting strip 12 to be inserted; a sealing gasket is provided between the contact surfaces of the hot air blower body 1 and the air inlet pipe 11.

[0025] Furthermore, when the hot air blower body 1 is working, air enters the connecting pipe 2 through the mesh plate 41 at the bottom of the collection cylinder 4. After being filtered and dehumidified, it enters the hot air blower body 1 through the air inlet pipe 11. The mesh plate 41 can intercept large particles in the air, preventing them from entering the connecting pipe 2. The air entering the connecting pipe 2 is filtered again through the filter cylinder 32 to remove even finer impurities. The air after this second filtration continues to flow upward, passing through the silica gel desiccant filter plate 34. The silica gel desiccant filter plate 34 can efficiently adsorb moisture in the air, reducing humidity. The air after being treated by the silica gel desiccant filter plate 34 continues to flow upward, passing through the activated carbon desiccant filter plate 36. The activated carbon desiccant filter plate 36 can not only further absorb moisture but also adsorb odors and harmful gases in the air, providing cleaner air. The air after filtration and dehumidification is heated by the hot air blower body 1 and then discharged, providing dry and warm air. The docking strip 12 and docking groove design facilitate the docking installation of the connecting pipe 2 and the air inlet pipe 11. The sealing gasket design ensures good airtightness between the two, preventing air leakage. The detachable design of the silica gel desiccant filter plate 34 and the activated carbon desiccant filter plate 36 makes it convenient to replace them after the device has been used for a period of time.

[0026] Example 2:

[0027] Please see Figure 2-3 This embodiment provides a technical solution based on embodiment one: a cleaning component is provided on the outside of the filter cylinder 32. The cleaning component includes an annular plate 51 rotatably disposed in the connecting pipe 2. A cleaning plate 52 is fixedly connected to the inner side of the annular plate 51. The cleaning plate 52 slides in contact with the outside of the filter cylinder 32. Multiple teeth 53 are uniformly fixedly connected to the outside of the annular plate 51. A driving component for driving the annular plate 51 to rotate is provided on the outside of the connecting pipe 2.

[0028] Specifically, the drive assembly includes a motor 61 fixedly installed outside the connecting pipe 2, a gear 62 fixedly connected to the output end of the motor 61, and the gear 62 meshing with the teeth 53 on the annular plate 51; a collection frame 42 is fixedly connected to the bottom of the inner wall of the collection cylinder 4, and the diameter of the collection frame 42 is larger than the diameter of the filter cylinder 32.

[0029] Furthermore, when a significant amount of dust accumulates on the surface of the filter cartridge 32, the motor 61 is activated, driving the gear 62 to rotate. The gear 62 meshes with the teeth 53 on the annular plate 51, causing the annular plate 51 to rotate and drive the cleaning plate 52 to clean the surface of the filter cartridge 32. The cleaning plate 52 slides in contact with the outside of the filter cartridge 32, effectively removing dust and impurities adhering to the surface of the filter cartridge 32. The cleaned-off dust and other impurities fall into the collection frame 42 at the bottom of the collection cartridge 4 for convenient and unified disposal.

[0030] Working Principle: When the hot air blower body 1 is working, air enters the connecting pipe 2 through the mesh plate 41 at the bottom of the collection cylinder 4. The mesh plate 41 intercepts large particles of debris in the air, preventing them from entering the connecting pipe 2. The air entering the connecting pipe 2 is filtered again through the filter cylinder 32 to remove even finer impurities. After being filtered again, the air continues to flow upward and efficiently adsorbs moisture from the air through the silica gel desiccant filter plate 34. The air treated by the silica gel desiccant filter plate 34 continues to flow upward and further removes moisture through the activated carbon desiccant filter plate 36, while also adsorbing odors and harmful gases in the air, providing cleaner air. The filtered and dehumidified air is heated by the hot air blower body 1 and then discharged, providing dry and warm air. When a lot of dust accumulates on the surface of the filter cylinder 32, the motor 61 is started, driving the gear 62 to rotate, causing the annular plate 51 to rotate, which in turn drives the cleaning plate 52 to clean the surface of the filter cylinder 32. The cleaned dust and other impurities fall into the collection frame 42, and the impurities can be disposed of by removing the collection cylinder 4.
