[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 8 , the present invention provides a technical solution:

[0032] Example 1: A humidity-adjustable indoor fresh air purification device includes a fresh air box 35, one side of the fresh air box 35 is connected to the air inlet pipe 36, and the other side of the fresh air box 35 is provided with a pair of symmetrically distributed air outlet mesh ports 37, and an installation groove 38 is provided between the adjacent pair of air outlet mesh ports 37, and a humidifier assembly is provided inside the installation groove 38.

[0033] By setting the air outlet mesh port 37, fresh air exhaust is achieved, and the humidifier component is set between a pair of air outlet mesh ports 37 to facilitate rapid mixing of the humidified air flow and the fresh air flow.

[0034] The humidifier assembly includes an atomizing unit 4, an air inlet unit 5 and a water inlet unit 6. A transfer box 1 is installed in the installation groove 38. The first connecting pipe 2 and the second connecting pipe 3 are installed obliquely on both sides of the upper end of the transfer box 1. Three layers of inner cavity are provided in the transfer box 1. The transfer inner cavity 8 at the upper end is connected to the first connecting pipe 2 and the second connecting pipe 3. A curved filter 10 is provided between the recovery inner cavity 9 in the middle layer and the transfer inner cavity 8.

[0035] By arranging the inclined first connecting pipe 2 and the second connecting pipe 3, water vapor gathers into droplets during the flow of the humidified air flow in the pipe, falls along the inclined surface and falls into the recovery cavity 9 through the curved filter 10, thereby preventing water droplets from dripping along the pipe and causing water seepage in the ceiling.

[0036] A water tank 17 is provided on one side of the transfer box 1 near the end of the installation groove 38, the first connecting pipe 2 extends to the outside of the installation groove 38, the second connecting pipe 3 is connected to the atomization unit 4, and one side of the lower inner cavity is horizontally connected to the water tank 17. A telescopically driven piston block 24 is provided in the water tank 17, and a folding pipe 21 connected to the water inlet unit 6 is provided in the installation groove 38, and the folding pipe 21 is connected to the lower inner cavity of the transfer box 1.

[0037] By setting a telescopically driven piston block 24, the water flow in the water tank 17 is squeezed into the folding tube 21 and enters the water inlet unit 6 for water supply. When the water needs to be changed, the piston block 24 is reset. Under the action of air pressure suction, the residual water flow in the folding tube 21 and the water inlet unit 6 is sucked back into the water tank 17. At this time, the water can be changed by simply disassembling the transfer box 1.

[0038] Working principle: first connect the transfer box 1 with the folding tube 21, then install the transfer box 1 in the installation groove 38, use the telescopic drive of the piston block 24 to transport the water flow in the water tank 17 to the water inlet unit 6 to supply water to the humidifier assembly, and use the atomizing unit 4 of the humidifier assembly to generate a humidified airflow, which is discharged along the second connecting pipe 3, the transfer inner cavity 8 and the first connecting pipe 2. The humidified airflow is between a pair of air outlet mesh ports 37, which facilitates the rapid mixing of the humidified airflow and the fresh airflow. During the flow of the humidified airflow in the pipeline, water vapor gathers into droplets, falls along the inclined surface and falls into the recovery inner cavity 9 through the curved filter 10, preventing water droplets from dripping along the pipeline and causing water seepage in the ceiling. When the water needs to be changed, the piston block 24 is reset, and under the action of air pressure suction, the residual water flow in the folding tube 21 and the water inlet unit 6 is sucked back into the water tank 17. At this time, you only need to disassemble the transfer box 1 to achieve water change.

[0039] Example 2: On the basis of Example 1, in order to achieve the positioning, installation and fixation of the transfer box 1, the end of the first connecting pipe 2 is connected to the air outlet pipe 7, and the port of the air outlet pipe 7 extends to the outside of the installation groove 38. The inclination angle between the first connecting pipe 2 and the transfer box 1 is smaller than the angle between the second connecting pipe 3 and the transfer box 1.

[0040] Through the relative tilt angle, the stable flow of air is ensured to avoid backflow.

[0041] A mounting base plate 39 is provided at the lower end of the mounting groove 38, a guide rail 14 is provided on the mounting base plate 39, a slide groove 15 with a T-shaped cross-section is provided on the guide rail 14, a slide bar 20 is provided at the lower end of the water tank 17 for slidingly plugging with the slide groove 15, a vertically arranged mounting tube 18 is provided at the end of the water tank 17, a screw hole 16 is provided in the slide groove 15 facing the mounting tube 18, a fixing screw 19 threadedly mounted on the screw hole 16 is inserted in the mounting tube 18, the middle section of the curved filter 10 is bent downward, and a one-way valve 11 is provided between the recovery inner cavity 9 and the lower inner cavity of the transfer box 1, and the one-way valve 11 allows the liquid in the recovery inner cavity 9 to flow to the lower inner cavity of the transfer box 1.

[0042] By setting the cooperation between the slide bar 20 and the slide groove 15, the positioning plug-in installation is achieved, and the cooperation between the fixing screw 19 and the screw hole 16 is utilized to achieve the fixed installation of the water tank 17 on the guide rail 14. By setting the one-way valve 11, overflow of the lower inner cavity of the water flow box is avoided during the extrusion process of the piston block 24, so that when the piston block 24 is reset, the water flow collected in the recovery inner cavity 9 is reversely adsorbed under the action of suction, thereby achieving the purpose of automatic cleaning.

[0043] A pneumatic telescopic rod 12 is provided in the water tank 17, and the telescopic end of the pneumatic telescopic rod 12 is connected to the piston block 24. A first baffle ring 25 is provided at the connection between the water tank 17 and the lower inner cavity of the transfer box 1, and a second baffle ring 26 is provided at the fixed end of the pneumatic telescopic rod 12. The inner diameter of the middle hole of the first baffle ring 25 and the second baffle ring 26 is smaller than the outer diameter of the piston block 24. The first baffle ring 25 and the second baffle ring 26 are both provided with sealing ring grooves, and the piston block 24 is provided with a sealing ring 27 pressed into the sealing ring groove.

[0044] By providing a cooperation between a retaining ring and a sealing ring 27, the moving position of the piston block 24 is sealed. When the pneumatic telescopic rod 12 is extended, the piston block 24 is pressed against the first retaining ring 25, which limits the moving position of the piston block 24 and realizes sealing at the same time to prevent water from reversely penetrating to the other side of the piston block 24. When the pneumatic telescopic rod 12 is reset, the piston block 24 is pressed against the second retaining ring 26, which also forms a seal.

[0045] Example 3: On the basis of Example 2, in order to reduce costs and avoid setting electrical drive elements in the water tank 17, cylinders 32 are symmetrically arranged on both sides of the water tank 17, and a piston rod 31 is inserted in the cylinder 32. The cylinder 32 is connected to the inner cavity of the fixed end of the pneumatic telescopic rod 12 through a connecting pipe 34, and a right-angle block 28 that cooperates with the piston rod 31 for extrusion is provided on the mounting base 39; a spring 33 is sleeved on the piston rod 31, and an end plate 42 is provided at the end of the piston rod 31 extending to the outside of the cylinder 32, one end of the spring 33 rests on the end plate 42, and the other end of the spring 33 rests on the end of the cylinder 32.

[0046] By arranging the cooperation between the cylinder 32 and the piston rod 31, the piston rod 31 is squeezed during the plugging process of the transfer box 1 and the water tank 17, so that the air flow in the cylinder 32 enters the pneumatic telescopic rod 12. Under the movement of plugging and installation, the piston block 24 is driven to move, squeezing the water flow in the water tank 17, thereby realizing water supply to the water inlet unit 6. By arranging the spring 33, the piston block 24 is automatically reset under the reset elastic force of the spring 33 during the disassembly and extraction process.

[0047] A positioning rod 29 is provided on the end plate 42, and the lower end of the right-angle block 28 is screwed to the mounting base plate 39. A plurality of groups of spaced-apart reinforcing ribs 40 are provided between the vertical surfaces of the right-angle block 28, and a through hole 30 is provided on the vertical surface of the right-angle block 28 to cooperate with the positioning rod 29.

[0048] By arranging the cooperation between the positioning rod 29 and the through hole 30 , the precise position correspondence between the piston rod 31 and the right-angle stopper 28 is achieved.

[0049] A vertical plate is vertically provided at one end of the guide rail 14 near the humidifier assembly. One end of the folding tube 21 is connected to the water inlet unit 6 through a right-angle connecting tube 22 connected to the vertical plate. The other end of the folding tube 21 extends parallel to the guide rail 14, and the end is connected to a second interface 41. A first interface 13 connected to the lower inner cavity of the transfer box 1 is provided at the lower end of one side of the transfer box 1 near the folding tube 21. The first interface 13 is connected to the second interface 41. A pair of guide rods 23 distributed in a circular array are provided on the second interface 41. The guide rods 23 slide through the vertical plate at the end of the guide rail 14.

[0050] The first interface 13 and the second interface 41 are provided to realize the communication between the folding tube 21 and the water tank 17 , and the folding tube 21 is adapted to the plug-in installation of the transfer box 1 and the water tank 17 .
