To sum up, the present invention is different from the prior art in that, in order to make the nozzle align with the sterilization plate for disinfection, the mechanical transmission principle adopted is an electric cylinder driving a cam structure. Compared with the prior art which uses a complex ratchet to drive the screw and also requires coordinated actions such as belt transmission, a large amount of transmission mechanism is saved. The transmission structure of the present invention is simpler and easy to assemble.

[0016] 2. When the action rod of the electric cylinder is extended and retracted, the synchronous rod will also drive the connecting rod structure to reciprocate, and the connecting rod structure will drive the nozzle to swing up and down relative to the air inlet surface of the sterilization plate, thereby increasing the sterilization area and also improving the sterilization efficiency. In order to make the nozzle swing up and down relative to the air inlet surface of the sterilization plate, the power used also comes from the electric cylinder, and only a connecting rod structure with low cost and simple structure needs to be set between the synchronous rod and the hose where the nozzle is located. Compared with the existing technology, it not only improves the function, but also has a lower manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figure 1-Figure 7 As shown:

[0027] The present embodiment provides a catalytic biological carbon reduction device, including a box body 1, the air inlet end of the box body 1 is connected to an air inlet pipe 2, the air outlet end is connected to an air outlet pipe 3, a sterilization plate 4 is arranged in the air inlet pipe 2, a nozzle 5 is arranged in the air inlet pipe 2, an electric cylinder 6 is arranged in the air inlet pipe 2, and a cam connecting rod mechanism 7 and a piston cylinder 9 are arranged outside the air inlet pipe 2. The cam connecting rod mechanism 7 includes a slide rail 72 fixed on the outer top surface of the air inlet pipe 2, a slider 73 slidingly fitted in the slide rail 72, and a cam 71 contacting the involute surface of the slider 73. The piston cylinder 9 is fixed on the outer top surface of the air inlet pipe 2, the piston cylinder 9 is vertically arranged, and a vertically upward piston 91 is arranged inside, and a piston rod 92 is connected to the piston 91, and the other end of the piston rod 92 extends outside the piston cylinder 9 and is connected On the cam 71, the top of the piston cylinder 9 is closed, and a spring 93 is connected between the top of the piston 91 and the top of the piston cylinder 9. A through groove 10 is provided on the air inlet pipe 2. The top of the through groove 10 is communicated with the slide rail 72, and the bottom of the through groove 10 is communicated with the box body 1. A synchronization rod 74 is fixed to the bottom of the slider 73, and the synchronization rod 74 extends into the box body 1 through the through groove 10. The action rod of the electric cylinder 6 is connected to the synchronization rod 74. A connecting rod structure 11 is hinged between the synchronization rod 74 and the nozzle 5. The synchronization rod 74 drives the slider 73 to move in a straight line, and the involute surface of the slider 73 drives the cam 71 to rise and fall. At the same time, the nozzle 5 is driven to swing up and down relative to the air inlet surface of the sterilization plate 4 through the connecting rod structure 11. Check valves are installed on the liquid infusion tube 14 and the hose on the nozzle 5.

[0028] like Figure 1 , Figure 4 As shown, a blocking cover 12 is fixed to the top of the intake pipe 2, and the piston cylinder 9 and the cam connecting rod mechanism 7 are located in the blocking cover 12 to form protection.

[0029] like Figure 1 , Figure 4 As shown, a liquid storage bottle 13 is fixed on the air intake pipe 2, and a liquid replenishing tube 14 is connected to the liquid storage bottle 13. The other end of the liquid replenishing tube 14 passes through the baffle cover 12 and is connected to the piston cylinder 9.

[0030] When the carbon reduction equipment is in use, the external air enters the air intake pipe 2, and after being processed by the sterilization plate 4, bacteria will be left on the air intake surface of the sterilization plate 4. The nozzle 5 is used to spray the sterilizing liquid on the air intake surface of the sterilization plate 4 to inactivate them (the prior art has been disclosed and will not be described in detail). The implementation scheme of the nozzle 5 of the present invention is different from the prior art. The spraying principle is as follows: when the action rod of the electric cylinder 6 is extended and retracted, the synchronous rod 74 will bring the slider 73 to reciprocate along the slide rail 72. When the slider 73 moves toward the direction of the cam 71, the involute surface is used to squeeze the cam 71, so that the cam 71 rises, and the cam 71 is moved upward. 1 brings the piston rod 92 up, and the piston rod 92 brings the piston 91 up, and a negative pressure is formed in the bottom space of the piston 91. At this time, the one-way valve on the liquid replenishing tube 14 is opened, and the sterilizing liquid is replenished from the liquid storage bottle 13 to the piston cylinder 9 by using the liquid replenishing tube 14. As the piston 91 rises, the spring 93 will be compressed and shortened. When the slider 73 is away from the cam 71, the spring 93 rebounds and becomes longer, and pushes the piston 91 down. The bottom space of the piston 91 forms a pressure, and as the piston 91 descends, the one-way valve on the hose where the nozzle 5 is located is pushed open, and then the sterilizing liquid is sprayed from the nozzle 5 to the air inlet surface of the sterilization plate 4 to complete the cleaning. In summary, the present invention is different from the prior art in that in order to make the nozzle 5 align with the sterilization plate 4 for disinfection, the mechanical transmission principle adopted is that the electric cylinder 6 drives the cam structure, which saves a lot of transmission mechanisms compared with the prior art that uses a complex ratchet to drive the lead screw, and also needs to be matched through belt transmission and other actions. The transmission structure of the present invention is simpler and easy to assemble.

[0031] In addition, when the action rod of the electric cylinder 6 is extended and retracted, the synchronous rod 74 will also drive the connecting rod structure 11 to reciprocate, and the connecting rod structure 11 will drive the nozzle 5 to swing up and down relative to the air inlet surface of the sterilization plate 4, thereby increasing the sterilization area and also improving the sterilization efficiency. In order to make the nozzle 5 swing up and down relative to the air inlet surface of the sterilization plate 4, the power used also comes from the electric cylinder 6, and only the connecting rod structure 11 with low cost and simple structure needs to be set between the synchronous rod 74 and the hose where the nozzle 5 is located. Compared with the prior art, it not only improves the function, but also has a lower manufacturing cost.

[0032] In another embodiment, during actual assembly, several nozzles 5 may be provided, and the nozzles 5 are distributed along the width direction of the tube cavity of the air inlet pipe 2, and the nozzles 5 are connected to the same hose through metal tubes, and the nozzles 5 are all bent toward the air inlet surface of the sterilization plate 4, and the connecting rod structure 11 is hinged on the bent portion of the hose of one of the nozzles 5. Driven by the hose, one nozzle 5 sprays sterilizing liquid relative to the air inlet surface of the sterilization plate 4 to complete the disinfection operation, and also drives other nozzles 5 to spray sterilizing liquid toward the sterilization plate 4 in the width direction, so that the cleaning efficiency is further improved.

[0033] like Figure 4As shown, in another embodiment, a V-shaped groove 15 is provided at the bottom of the tube cavity of the air inlet pipe 2, and the V-shaped groove 15 is located on the air inlet side of the sterilization plate 4. The sterilization plate 4 is inclined in the air inlet pipe 2, and the bottom end of the sterilization plate 4 is inclined toward the direction of the V-shaped groove 15 and connected to the bottom surface of the tube cavity of the air inlet pipe 2. The top of the sterilization plate 4 is inclined toward the inner cavity of the box body 1 and connected to the top surface of the tube cavity of the air inlet pipe 2. A through hole 16 is provided at the top of the sterilization plate 4. A dust shield 8 is fixed in the air inlet pipe 2, and the synchronization rod 74 is located between the dust shield 8 and the sterilization plate 4. The action rod of the cylinder 6 passes through the through hole 16 and enters between the dust shield 8 and the sterilization plate 4 and is connected to the synchronization rod 74. The cylinder body of the electric cylinder 6 is located on the other side of the sterilization plate 4. The top of the dust shield 8 is inclined toward the air intake side of the air intake pipe 2 and is connected to the top surface of the tube cavity of the air intake pipe 2. The bottom of the dust shield 8 is inclined toward the direction of the V-shaped groove 15 and a gap 17 is left between the V-shaped groove 15. A collecting port 18 is provided at the bottom of the air intake pipe 2. A collecting cover 19 is provided on the bottom side of the air intake pipe 2. The top of the collecting cover 19 is connected to the collecting port 18 by threads. The dust shield 8 can intercept dust. The dust falls into the gap 17, flows from the gap 17 to the V-shaped groove 15, and then falls into the collecting cover 19 from the bottom of the V-shaped groove 15. The bacteria cleaned off the sterilization plate 4 will also fall into the V-shaped groove 15 and will eventually be collected in the collecting cover 19.

[0034] like Figure 5 , Figure 7 As shown, a sealing sleeve 20 is installed on the through port 16, and the actuating rod of the electric cylinder 6 also passes through the sealing sleeve 20. The connecting rod structure 11 deviates from one side of the actuating rod of the electric cylinder 6. A rubber 21 is fixed on the connecting rod structure 11, and the rubber 21 contacts the actuating rod of the electric cylinder 6. The sealing sleeve 20 isolates the cylinder body and the actuating rod of the electric cylinder 6. The cylinder body is close to the box body 1, and the actuating rod is located between the dust shield 8 and the sterilizing plate 4 in the air intake pipe 2. The dust, carbon dioxide and other impurities sucked into the air intake pipe 2 are only limited to the dust shield 8 and the sterilizing plate 4. They will not enter the cylinder body of the electric cylinder 6 under the isolation of the sealing sleeve 20, thereby preventing the actuating rod of the electric cylinder 6 from being blocked from extending and retracting. The installation position structure of the electric cylinder 6 is reasonable. When the connecting rod structure 11 is in motion, it comes into flexible contact with the actuating rod of the electric cylinder 6 through the rubber 21. Firstly, an inner support is formed for the connecting rod structure 11 to prevent the connecting rod structure 11 from deforming forward and backward. Secondly, when the connecting rod structure 11 is in motion, the rubber 21 is used to synchronously wipe the actuating rod of the electric cylinder 6, so that some dust attached to the actuating rod during air intake has a chance to be cleaned downward. The position of the connecting rod structure 11 is reasonably set.

[0035] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0036] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention.
