[0049] Embodiment 1:

[0050] An environmentally friendly floor with ventilation function, such as Figures 1 to 10As shown, it includes a floor main body 1 and a floor main body 2, the floor main body 1 and the floor main body 2 are fixed by a connecting piece, and a ventilation part is installed inside the floor main body 1, and the ventilation part includes:

[0051] Fixed block 10: It is fixed to the inner wall of the curved surface of the floor main body 1 by a pin, and a cylinder 8 is welded to one end of the fixed block 10 away from the floor main body 1, and a ventilation hole 2 15 is opened on the outer wall of the cylinder 8;

[0052] Insect-proof filter 12: It is fixed to one end of the cylinder 8 by embedding;

[0053] The pad 23 is welded to the surface of the insect-proof filter 12, and the through hole on the surface of the pad 23 is rotatably connected to the storage cylinder 27, and the outer wall of the storage cylinder 27 is welded with a cross scraper 13;

[0054] Cylinder 2 9: It is rotatably connected to the outer circumferential wall of cylinder 1 8, and the outer wall of cylinder 2 9 is provided with a ventilation hole 14 having the same inner diameter as ventilation hole 2 15, and one end of cylinder 2 9 is fixedly connected to the cross scraper 13;

[0055] The driving rod 35 is slidably connected to the inner wall of the through hole opened at one end of the storage tube 27, and the piston plate 26 is welded to one end of the driving rod 35, and the other end of the driving rod 35 is threadedly connected to the second conical block 29;

[0056] Spring 24: It is sleeved on the outer wall of the driving rod 35, and the two ends of the spring 24 are respectively fixed to the outer wall of one side of the conical block 29 and the outer wall of one side of the storage tube 27 by means of clamping;

[0057] Spray head 28: welded to the outer circumferential wall of storage tube 27;

[0058] Hose 22: It is connected to the outer wall of the storage tube 27 through a joint, and one end of the hose 22 is threadedly connected to the cover plate 11;

[0059] In this embodiment, the floor main body 1 and the floor main body 2 are preferably made of lignin fiberboard, which has the advantages of fire resistance, environmental protection, moisture resistance and sound insulation. The floor main body 1 and the floor main body 2 are used in combination, and the floor main body 1 and the floor main body 2 can be fixedly connected by a connecting piece during the combination process;

[0060] When in use, the insect-proof filter 12 is kept connected to the external environment. When the ventilation part is needed to realize ventilation between the indoor and outdoor environments, the storage cylinder 27 and the cross scraper 13 are driven to rotate, so that the cylinder 1 8 and the cylinder 2 9 rotate relative to each other. When the ventilation hole 14 on the cylinder 2 9 and the ventilation hole 2 15 on the cylinder 1 8 overlap with each other, the air from the external environment is introduced into the cylinder 1 8 through the insect-proof filter 12, and finally introduced into the room through the ventilation hole 2 15 and the ventilation hole 1 14. When the indoor windows are closed, ventilation between the indoor and outdoor environments is realized. When the external environment temperature is low, the cylinder 2 9 is driven to rotate so that the ventilation hole 14 and the ventilation hole 2 15 are in a mutually dislocated position, so that the external cold air is isolated, and the indoor temperature is prevented from decreasing. Flexible ventilation can be realized according to the external environment conditions.

[0061] The cross scraper 13 plays a role in preventing mosquitoes and dust during ventilation, preventing external dust or mosquitoes from entering the room. After the cross scraper 13 has been used for a period of time, the dust and mosquitoes attached to the surface of the cross scraper 13 can be scraped off by rotating the cross scraper 13 to prevent mosquitoes and dust from clogging the holes on the cross scraper 13, thereby affecting the ventilation effect. During the dust cleaning process, a certain amount of cleaning liquid can be injected into the storage cylinder 27 through the cover plate 11. When the cross scraper 13 is rotating, the driving rod 35 is pushed along the storage cylinder 27, so that the piston plate 26 squeezes out the cleaning liquid in the storage cylinder 27 through the nozzle 28 during the movement. The cleaning liquid is squeezed out from the nozzle 28 and sprayed onto the surface of the insect-proof filter 12, thereby soaking the surface of the insect-proof filter 12, so that when the blades 16 clean the surface of the insect-proof filter 12 during the rotation, the cleaning effect is improved with the cleaning liquid.

[0062] Furthermore, the connecting member includes a connecting plate 5 and a fastening screw member 7, and the upper and lower surfaces of the floor main body 1 and the floor main body 2 are both provided with a connecting groove 4, and the inner diameter of the connecting groove 4 is adapted to the outer diameter of the connecting plate 5, and the floor main body 1 and the floor main body 2 are fixedly connected by the connecting plate 5 and the fastening screw member 7;

[0063] When connecting the floor main body 1 and the floor main body 2 2, after aligning the floor main body 1 and the floor main body 2 2, the connecting plate 5 is placed in the connecting groove 4 on the floor main body 1 and the floor main body 2 2, and the surface of the connecting groove 4 and the surface of the connecting plate 5 are respectively provided with installation grooves and installation holes, and the fastening screw 7 and the installation groove on the connecting groove 4 are threadedly connected to achieve a fixed connection between the floor main body 1 and the floor main body 2 2.

[0064] Further, a vertical plate 17 is welded to the inner wall of the bottom of the cylinder 8, and an electric telescopic rod 34 is fixed to the outer wall of one side of the vertical plate 17 by screws, and a receiving plate 33 is fixed to the output end of the electric telescopic rod 34 by a pin, and a through hole opened on the surface of the receiving plate 33 is rotatably connected to a long gear 21, and a clamping seat 30 is welded to one end of the long gear 21, and the clamping seat 30 and the conical clamping block 29 are adapted to each other, a vertical plate 18 is welded to the inner wall of the bottom of the cylinder 8, and a driving motor 31 is fixed to the outer wall of one side of the vertical plate 18 by screws, and a driving gear 25 meshing with the long gear 21 is fixed to the output end of the driving motor 31 by a pin;

[0065] The driving motor 31 is used to drive the driving gear 25 to rotate. The driving gear 25 drives the long gear 21 to rotate during the rotation process. The electric telescopic rod 34 can drive the accommodating plate 33 and the long gear 21 to move horizontally. When the seat 1 30 at one end of the long gear 21 gradually moves toward the conical block 29, the seat 1 30 first pushes the conical block 29. After the conical block 29 is pushed, it pushes the piston plate 26, so that the cleaning liquid in the storage cylinder 27 is sprayed out through the nozzle 28 under the action of pressure. When the conical block 29 reaches the maximum moving distance, the pressure between the seat 1 30 and the conical block 29 is used to ensure that the seat 1 30 and the conical block 29 are clamped together, so that when the driving motor 31 drives the driving gear 25 to rotate, the long gear 21 drives the seat 1 30 and the conical block 29 to rotate, so as to gradually realize the rotation and cleaning of the dust on the surface of the insect-proof filter 12 by the cross scraper 13.

[0066] Furthermore, a clamping frame 6 is fixed to the top of the floor main body 1 by screws, and a rectangular ventilation net 3 is fixed to the top of the clamping frame 6 by clamping;

[0067] The rectangular ventilation net 3 can be provided to allow indoor air to enter and exit. By arranging the rectangular ventilation net 3 and the clamping frame 6 to be detachable, it is convenient to inject cleaning liquid into the storage cylinder 27 through the hose 22. At the same time, the rectangular ventilation net 3 protrudes from the upper surface of the clamping frame 6 to play a certain water-blocking role, effectively preventing water from entering the cylinder body 8 through the rectangular ventilation net 3 when water accumulates on the surface of the floor main body 1.

[0068] When the present embodiment is in use, firstly, the floor main body 1 and the floor main body 2 2 are assembled by connecting pieces, and then installed indoors. When indoor and outdoor ventilation is required, the electric telescopic rod 34 is used to drive the long gear 21 to move horizontally, and the long gear 21 drives the holder 1 30 to move in the direction close to the conical block 29. After the holder 1 30 is moved and engages with the conical block 29, the driving motor 31 is used to drive the cross scraper 13 and the cylinder 2 9 to rotate. When the ventilation hole 14 on the cylinder 2 9 and the ventilation hole 2 15 on the cylinder 1 8 overlap with each other, indoor and outdoor air circulation is achieved; during the rotation process, the cross scraper 13 cooperates with the cleaning liquid squeezed out by the piston plate 26 to scrape off the dust attached to the surface of the insect-proof filter 12, so as to prevent the dust from clogging the mesh on the surface of the insect-proof filter 12 and affecting normal ventilation.

[0069] Embodiment 2:

[0071] When the air flow rate needs to be accelerated, the electric telescopic rod 34 is used to drive the second holder 32 to move toward the direction close to the conical block 20. When the second holder 32 moves to engage with the conical block 20, the speed of the output end of the driving motor 31 is adjusted to drive the blades 16 to accelerate the indoor air circulation rate during high-speed rotation.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
