[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a ventilation system for a tourist boat includes a blower 1 with a built-in fan, which delivers treated sea air to various areas inside the cabin. A connecting frame 5 is installed at the air inlet of the blower 1. Two symmetrically distributed filter elements 6 are installed within the connecting frame 5, and a hollow column 16, coaxially distributed with the blower 1, is rotatably connected through the surface of the connecting frame 5. The two filter elements 6 within the connecting frame 5 are used alternately, ensuring that when one filter element 6 is cleaned, the other filter element 6 is used to filter the sea air, guaranteeing uninterrupted treatment and delivery of the sea air. The hollow column 16 is located on both sides of the connecting frame 5, and an outer cover 4 and an inner cover 7 are respectively installed thereon. The inner cover 7 is located between the connecting frame 5 and the fan, and a shower head 12 for backwashing and drying the filter elements 6 is slidably installed inside the inner cover 7. The shower head 12 is positioned between the inner wall of the inner cover 7 and the inner wall of the outer cover 4. Each is equipped with at least two electric telescopic rods 17. A perforated plate 11 is slidably installed inside the outer cover 4, and at least two through holes 18 are opened on the side of the outer cover 4 facing away from the connecting frame 5. The outer cover 4 and the inner cover 7 are rotated to the front and rear positions of one of the filter elements 6 by rotating the hollow column 16. The outer cover 4 and the inner cover 7 move relative to each other, and the front and rear of the aligned filter element 6 are covered by the relative openings of the outer cover 4 and the inner cover 7. The shower head 12 in the inner cover 7 sprays clean water and disinfectant water in sequence to achieve reverse rinsing and disinfection of the filter element 6. Then, the electric telescopic rod 17 extends to allow the perforated plate 11 and the shower head 12 to move relative to each other to pressurize the filter element 6 to achieve dehydration. After dehydration, the shower head 12 sprays hot air to dry the filter element 6. During the process of squeezing the filter element 6, the squeezed dirty water enters the outer cover 4 through the perforated plate 11 and is finally discharged through the through holes 18 on the surface of the outer cover 4.

[0024] To achieve cleaning and drying of the filter element 6: A three-way valve 8 is fixedly installed inside the blower duct 1 on the side of the inner cover 7 facing away from the connecting frame 5. One port of the three-way valve 8 is coaxially set with the blower duct 1 and is rotatably installed with a connecting pipe 9 via a rotary joint. The other end of the connecting pipe 9 passes through the inner cover 7 and is sleeved at the water inlet of the shower head 12. The other two ports of the three-way valve 8 are respectively connected to the water inlet pipe 2 and the air inlet pipe 3, which are connected to the outside of the blower duct 1. The port switch on the surface of the three-way valve 8 controls the connection between the connecting pipe 9 and the water inlet pipe 2 or the air inlet pipe 3. The water inlet pipe 2 is used in conjunction with a water pump, and the air inlet pipe 3 is used in conjunction with a hot air blower. This allows the water for rinsing to enter the shower head 12 through the water inlet pipe 2, the three-way valve 8, and the connecting pipe 9; or the hot air generated by the hot air blower to enter the shower head 12 through the air inlet pipe 3, the three-way valve 8, and the connecting pipe 9, and finally spray out to dry the inside of the filter element 6.

[0025] To achieve alternating cleaning of the upper and lower filter elements 6: a motor 10 is fixedly installed on the outer wall of the three-way valve 8, which is coaxial with the blower 1. The main shaft of the motor 10 is fixedly installed at one end of the hollow column 16. Since the three-way valve 8 is connected to the port of the connecting pipe 9 through a rotary joint, the motor 10 drives the hollow column 16 to rotate the outer cover 4 and the inner cover 7. The rotary joint ensures that the three-way valve 8, the water inlet pipe 2, and the air inlet pipe 3 will not rotate.

[0026] To ensure smooth relative or opposite movement of the outer cover 4 and the inner cover 7: a gear 15 is rotatably connected inside the hollow column 16, and racks 14 are installed through both ends of the hollow column 16. The two racks 14 are staggered vertically with their tooth surfaces facing each other. The opposing tooth surfaces of the two racks 14 mesh with the gear 15, and one end of the two racks 14 is fixed to the surface of the outer cover 4 and the inner cover 7 respectively. One rack 14 is sleeved on the main shaft of the motor 10. The outer cover 4 and the inner cover 7 are sleeved on the hollow column 16. An electric push rod 13 for driving the movement of the outer cover 4 is fixedly installed at one end of the hollow column 16. In use, the outer cover 4 is moved by retracting the electric push rod 13, thereby moving the rack 14 connected to the outer cover 4. 4. Movement: Under the meshing action of gear 15, the other rack 14 moves relative to the inner cover 7. The connection between the other rack 14 and the inner cover 7 allows the outer cover 4 and the inner cover 7 to move relative to each other. Furthermore, the through-hole connection between the rack 14 and the end of the hollow column 16 ensures that the rack 14 will not rotate within the hollow column 16. Therefore, the outer cover 4 or inner cover 7, fixedly connected to the rack 14, will not rotate relative to the hollow column 16, but will rotate with the rotation of the hollow column 16. Additionally, the outer cover 4 and inner cover 7 are fitted onto the hollow column 16, ensuring that they can slide relative to each other. In this design, "one rack 14 is fitted onto the main shaft of the motor 10" is combined with... Figure 4 As you can understand, the rack 14 on the right side is mounted on the main shaft of the motor 10, so when the motor 10 drives the hollow column 16 to rotate, it can drive the rack 14 on the right side to rotate synchronously.

[0027] Working principle: During use, the motor 10 drives the hollow column 16 to rotate the outer cover 4 and the inner cover 7 to both sides of the filter element 6 that needs to be cleaned. The outer cover 4 and the inner cover 7 move relative to each other until their relative openings cover the front and back of the filter element 6. Cleaning water and disinfectant water enter the shower head 12 through the inlet pipe 2, the three-way valve 8, and the connecting pipe 9 to achieve reverse rinsing and disinfection of the filter element 6. After the reverse rinsing is completed, the electric telescopic rod 17 extends to move the perforated plate 11 and the shower head 12 relative to each other to pressurize the filter element 6 and achieve dehydration. During the process of squeezing the filter element 6, the squeezed dirty water enters the outer cover 4 through the perforated plate 11 and is finally discharged through the through hole 18 on the surface of the outer cover 4. After dehydration, the hot air generated by the hot air blower enters the shower head 12 through the air inlet pipe 3, the three-way valve 8, and the connecting pipe 9 and is finally sprayed out to dry the inside of the filter element 6.

[0028] The wiring diagrams of the fan, three-way valve 8, motor 10, electric push rod 13, and electric telescopic rod 17 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the fan, three-way valve 8, motor 10, electric push rod 13, and electric telescopic rod 17 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
