[0002] With the rapid development of modern building technology and the continuous improvement of people's quality of life, the comfort and health of indoor environment have received more and more attention. Especially in confined spaces or crowded places such as offices, shopping malls, hospitals, etc., insufficient indoor oxygen content has become an important factor affecting people's health and work efficiency.

[0003] The traditional indoor oxygen supply method mainly relies on ventilation by opening windows or using ventilation equipment. Although ventilation by opening windows can introduce fresh air, it is greatly affected by the external environment and the ventilation effect is not good.

[0035] Embodiment 1, as Figure 1 to Figure 2 As shown, an intelligent indoor oxygen supply device for a building comprises a horizontally laid ventilation duct, wherein one end of the ventilation duct located outdoors is set as an air inlet, and one end located indoors is set as an exhaust port, one side of the ventilation duct is connected with a first storage box 1 for storing an air filter element before use, and the opposite side of the ventilation duct is connected with a second storage box 2 for storing an air filter element after use, and the interiors of the ventilation duct and the first storage box 1 are both provided with a cylindrical air filter element, and the first storage box 1 and the second storage box 2 are both located at the same height as the air filter element; the air filter element is fixedly mounted on one end of a mounting plate 3 close to the windward side, and there is a gap between the mounting plate 3 and the outer wall of the air filter element, and the end of the mounting plate 3 close to the windward side is in a fully open state, and a through hole is penetrated and opened at one end of the mounting plate 3 close to the leeward side, and the diameter of the through hole is smaller than the inner diameter of the air filter element, and the two side walls of the mounting plate 3 close to the first storage box 1 and the second storage box 2 form a seal for the ventilation duct; a push rod 4 is arranged on the side of the first storage box 1 away from the second storage box 2, one end of the push rod 4 penetrates the first storage box 1 and slides with it, and one end of the push rod 4 is connected with a driving mechanism.

[0036] In this embodiment, an air flow meter is arranged between the air inlet near the ventilation duct and the air filter element. When the air filter element is blocked, the air intake volume will decrease, and the air flow meter will detect this change and send a signal to the driving mechanism. The driving mechanism starts to work to replace the air filter element, and the fan blades of the oxygen supply equipment are suspended in advance. Then, the driving mechanism drives the push rod 4 to move horizontally to replace the air filter element in the ventilation duct, and the air filter element stored in the first storage box 1 is pushed into the ventilation duct, and the air filter element originally located in the ventilation duct is pushed into the second storage box 2 for storage. Two sets of support strips are arranged in parallel on the inner wall of the ventilation duct, which are respectively located at the two ends of the mounting plate 3. The air filter element can slide along the support strips, so that the air filter element can be replaced smoothly without blocking the ventilation of the duct.

[0037] During the process of replacing the air filter in the ventilation duct, a sealed state is formed between the two mounting plates 3, blocking the outdoor airflow from directly entering the room. The dual air filter structure can prevent the outdoor airflow from entering the room when the air filter is replaced, and dust is discharged into the room along with the airflow, polluting the indoor environment.

[0038] like Figure 4 As shown, the specific structure of this embodiment is that the driving mechanism includes a forward and reverse motor 8, which is installed on the outer wall of the ventilation duct, and the output end of the forward and reverse motor 8 is fixedly connected to a threaded rod 801, and the outer side of the threaded rod 801 is threadedly connected to a second slider 7, and the second slider 7 is fixed to one end of the push rod 4.

[0039] In this embodiment, when the forward and reverse motor 8 starts to work, the threaded rod 801 is driven to rotate and drive the second slider 7 to move horizontally toward the ventilation duct. The movement of the second slider 7 drives the push rod 4 to move. The push rod 4 moves and pushes the mounting plate 3 in the first storage box 1 to replace the mounting plate 3 in the ventilation duct.

[0040] The driving mechanism here can also use an electric push rod as a driving member.

[0041] Embodiment 2, as Figures 3 to 9 As shown, further, the outer side of the threaded rod 801 is threadedly connected to the first slider 6, the top end of the first slider 6 is fixedly connected to the second baffle 14 and the third baffle 15, and the bottom end of the first slider 6 is fixedly connected to the first baffle 16; the third baffle 15 and the first baffle 16 are both sealed and slidably connected to the inside of the ventilation duct, and the third baffle 15 and the first baffle 16 are respectively located at the two ends of the air filter element; the inner wall of the ventilation duct is provided with a strip groove 17 adapted to the third baffle 15 and the first baffle 16; one side of the ventilation duct is connected to the branch duct 13, and the second baffle 14 is sealed and slidable inside the branch duct 13; smooth surfaces are provided on the outer sides of both ends of the threaded rod 801, and telescopic parts are provided on the outer sides of the two smooth surfaces; the first slider 6 and the second slider 7 are connected by an extrusion assembly 9.

[0042] In this embodiment, the initial position of the second baffle 14 is located inside the branch pipe 13 to seal the branch pipe 13 and increase the service life of the spare air filter element. The initial positions of the third baffle 15 and the first baffle 16 are located outside the ventilation duct.

[0043] The initial positions of the first slider 6 and the second slider 7 are both located on the smooth surface on the same side, and the first slider 6 and the second slider 7 are in contact with each other, and at the same time, one end of the extrusion assembly 9 is in contact with the telescopic member on one side;

[0044] When the air flow meter detects that the air filter element in the ventilation duct is clogged, the forward and reverse motors 8 are running, and the extrusion assembly 9, under the force of the elastic member and the drive of the forward and reverse motors 8, first drives the first slider 6 to move horizontally toward the ventilation duct, and the movement of the first slider 6 drives the third baffle 15 and the first baffle 16 to move together to seal the two ends of the air filter element in the ventilation duct. At the same time, the first slider 6 drives the second baffle 14 to move to open the branch duct 13. At this time, the oxygen supply equipment can work without stopping, and the ventilation duct is switched to the branch duct 13 for continuous oxygen supply;

[0045] When the first slider 6 reaches the smooth surface on the other side from the smooth surface on one side, the forward and reverse motors 8 continue to run, and the second slider 7 starts to move linearly toward the ventilation duct under the force of the extrusion assembly 9, pushing the air filter element in the first storage box 1 into the ventilation duct, and at the same time pushing the air filter element originally in the ventilation duct into the second storage box 2 for storage.

[0046] Furthermore, a spare air filter is arranged inside the branch pipe 13, and the spare air filter is located at the same height as the air filter in the ventilation duct; the second baffle 14 is located on the top of the spare air filter, and when switching to the branch pipe 13 for continuous oxygen supply, the dust in the airflow can be purified by the spare air filter.

[0047] like Fig.10 As shown, as the specific structure of this embodiment, the extrusion assembly 9 includes a pull rod 901, the pull rod 901 is fixedly connected to the side of the first slider 6 close to the second slider 7, and the end of the pull rod 901 close to the first slider 6 is connected to the extrusion plate 903 through the first spring 902; the cross-sectional shape of the pull rod 901 is set to be L-shaped; the pull rod 901 passes through the second slider 7 and slides with the second slider 7.

[0048] In this embodiment, when the forward and reverse motors 8 rotate to drive the first slider 6 to move toward the ventilation duct, the pull rod 901 is driven to slide in the second slider 7. The number of pull rods 901 here is set to two, which are symmetrically arranged on one side of the first slider 6. When the first slider 6 moves to drive the third baffle 15 and one end of the first baffle 16 to contact the inner wall of the ventilation duct, one end of the extrusion plate 903 fits with the second slider 7, and the force of the first spring 902 acts on the second slider 7 through the extrusion plate 903. The two symmetrically arranged pull rods 901 improve the stability of the extrusion force of the extrusion plate 903 on the second slider 7. Combined with the drive of the threaded rod 801, the second slider 7 starts to move linearly toward the ventilation duct. The movement of the second slider 7 drives the push rod 4 to move, and the air filter element is replaced.

[0049] When the air filter element is replaced, the position of the second slider 7 is located on a smooth surface close to the forward and reverse motor 8. At this time, the forward and reverse motor 8 stops running, and the second slider 7 overcomes the force of the elastic member and moves from the external thread of the threaded rod 801 to the smooth surface. At this time, the second slider 7 squeezes the first slider 6 originally located on the smooth surface and moves toward the ventilation duct. The moving distance is equal to the thickness of the second slider 7, and the depth of the preset strip groove 17 in the ventilation duct is greater than the thickness of the second slider 7, and the widths of the third baffle 15 and the first baffle 16 are both greater than the cross-sectional width of the ventilation duct. Therefore, the first slider 6 moves, driving the third baffle 15 and the first baffle 16 to continue to move toward the strip groove 17 on the inner wall of the ventilation duct, further improving the sealing performance.

[0050] like Figure 7 As shown, further, the telescopic member includes a second spring 10, one end of which is fixedly connected to a support plate 11, and the second spring 10 and the support plate 11 are both non-contactly sleeved on the outside of the threaded rod 801; the other end of the second spring 10 is fixed to the support plate, and the threaded rod 801 passes through the support plate and rotates therewith.

[0051] In this embodiment, one of the support plates in the present application is installed at one end of the first storage box 1 away from the air inlet, and the other support plates are installed on the outer wall of the ventilation duct. The force of the second spring 10 acts on the first slider 6 and the pull rod 901 through the support plate 11. The support plate 11 is arranged in a circular shape, which further improves the stability of the contact with the first slider 6 and the pull rod 901.

[0052] like Fig.11 As shown, further, one side of the ventilation duct close to the branch duct 13 is connected to an adsorption assembly 5 , the adsorption assembly 5 is arranged between the third baffle 15 and the air filter element, and the adsorption assembly 5 is connected to the driving mechanism through the energy storage assembly 12 .

[0053] In the present embodiment, when replacing the air filter element, the third baffle 15 and the first baffle 16 are driven by the driving mechanism to move toward the inside of the ventilation duct to seal the ventilation duct, and the oxygen supply equipment continues to work. The duct is switched to the branch duct 13 for continuous oxygen supply, and then the push rod 4 is driven to move toward the first storage box 1 to replace the air filter element in the ventilation duct. When the driving mechanism drives the push rod 4 to move to replace the air filter element, the energy storage component 12 is driven to store energy. After the driving mechanism stops working, the adsorption component 5 is driven by the energy storage component 12 to adsorb the dust generated by replacing the air filter element.

[0054] like Fig.12As shown, the specific structure of this embodiment is that the energy storage component 12 includes a round rod 1201, which is rotatably connected to one end of the threaded rod 801 through a one-way damping bearing, a sleeve 1203 is sleeved on the outer side of the round rod 1201, and the round rod 1201 and the sleeve 1203 are connected through a clockwork spring 1202; the sleeve 1203 is fixedly connected to the side wall of the support plate, and the end of the round rod 1201 away from the threaded rod 801 is rotatably connected to an L-shaped rod 1204 through a one-way damping bearing, and the end of the L-shaped rod 1204 close to the adsorption component 5 is rotatably connected to a protrusion.

[0055] In this embodiment, the forward and reverse motor 8 drives the threaded rod 801 to rotate, and drives the round rod 1201 to rotate multiple times to accumulate force to overcome the force of the spring 1202. At this time, the rotation of the round rod 1201 does not drive the L-shaped rod 1204 to rotate. When the forward and reverse motor 8 stops working, the round rod 1201 rotates in the opposite direction under the force of the spring 1202. At this time, the spring 1202 rotates to drive the L-shaped rod 1204 to rotate multiple times. The rotation of the L-shaped rod 1204 drives the protrusion to revolve, and then drives the adsorption component 5 to absorb the dust between the third baffle 15 and the air filter when the air filter is replaced, so that the air filter is replaced and the adsorption component 5 is driven to absorb dust while accumulating force, without the need for additional power components, which is environmentally friendly and energy-saving.

[0056] After the adsorption component 5 finishes adsorbing the dust, the forward and reverse motor 8 can be started to drive the threaded rod 801 to rotate in the reverse direction. The threaded rod 801 rotates in the reverse direction, so that the second slider 7 and the first slider 6 move in sequence in the direction away from the ventilation duct under the action of the second spring 10, until the second slider 7 and the first slider 6 move to a smooth surface away from the forward and reverse motor 8 and reset. In this process, the reverse rotation of the threaded rod 801 does not drive the energy storage component 12 to store energy;

[0057] The process in which the forward and reverse motor 8 drives the threaded rod 801 to rotate in the reverse direction simultaneously drives the second baffle 14, the third baffle 15, and the first baffle 16 to reset, and switches the branch pipe 13 to a ventilation pipe for oxygen supply.

[0058] like Figure 13 to Figure 14 As shown, further, the adsorption component 5 includes a piston rod 501, and the two ends of the piston rod 501 are hinged to the protrusion and the piston 502 respectively; the piston 502 is sealed and slides inside the air cylinder 503, and the air cylinder 503 is installed on the side wall of the support plate; the air cylinder 503 is connected to the ventilation duct through the air inlet pipe 505, and the air cylinder 503 is connected to the air outlet pipe 504; control valves are provided on the outside of the air outlet pipe 504 and the air inlet pipe 505.

[0059] In this embodiment, when the L-shaped rod 1204 rotates in the opposite direction, it drives the piston rod 501 to perform reciprocating motion in the air cylinder 503. The reciprocating motion of the piston rod 501 drives the piston 502 to perform reciprocating linear motion inside the air cylinder 503. The dust between the third baffle 15 and the air filter element is adsorbed through the air inlet pipe 505, and then discharged into the dust removal bag through the air outlet pipe 504. The control valve located on the outside of the air inlet pipe 505 is a one-way air inlet valve, and the control valve on the outside of the air outlet pipe 504 is a one-way air outlet valve.

[0060] Furthermore, a third baffle plate 15 is sealingly and slidably connected to one side of the ventilation duct close to the branch duct 13 , and the third baffle plate 15 is fixed to the second baffle plate 14 , and the third baffle plate 15 is located on the top of the air filter element.

[0061] Furthermore, the second baffle 14 is fixedly connected to the top of the second slider 7. In the present embodiment, when the forward and reverse motor 8 drives the threaded rod 801 to rotate and drives the first slider 6 to make a linear motion toward the ventilation duct, the first slider 6 drives the third baffle 15 and the first baffle 16 to move simultaneously to seal the ventilation duct. At the moment when the third baffle 15 and the first baffle 16 seal the ventilation duct, the second slider 7 moves and drives the second baffle 14 to move, thereby opening the branch duct 13 to continuously supply oxygen, thereby preventing the ventilation duct from failing to form a closed state and opening the branch duct 13 at the same time. At this time, airflow passes through both the ventilation duct and the branch duct 13, thereby preventing dust intercepted on the air filter element in the ventilation duct from flowing back to the spare air filter element for a second time under the disturbance of the airflow, thereby reducing the service life of the spare air filter element.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
