[0033] Limiting components are arranged on both sides of the mounting frame 3, and the mounting frame 3 is limited and fixed by the limiting components.

[0034] Furthermore, the temperature control component includes a plurality of electric heating tubes 31 fixedly installed inside the mounting frame 3 , and resistance wires are fixedly installed inside the electric heating tubes 31 . The temperature control component heats the electric heating tubes 31 through the internal resistance wires to adjust the temperature of the air.

[0035] Furthermore, first slide grooves 12 are provided on the outer surfaces of both sides of the body 1, and slide rods 36 are fixedly installed on both sides of the mounting frame 3, and the slide rods 36 are arranged inside the first slide grooves 12. The mounting frame 3 is slidably connected to the body 1 through the slide rods 36, and the mounting frame 3 is pulled outward along the slide grooves.

[0036] Furthermore, the limiting assembly includes limiting rods 37 arranged on the outer surfaces of both sides of the body 1, and the outer surfaces of the body 1 are provided with limiting grooves 13 at both ends of the first slide groove 12, and one end of the limiting rod 37 matches the limiting groove 13, and the limiting blocks 37 on both sides of the mounting frame 3 are pulled outward, so that one end of the limiting block 37 is disengaged from the limiting groove 13 at one end of the first slide groove 12, thereby releasing the limitation of the mounting frame 3.

[0037] Furthermore, the sliding rod 36 is a hollow structure, and an inner rod 38 is provided inside the sliding rod 36, and one end of the inner rod 38 is fixedly connected to one end of the limiting rod 37, and a baffle 382 is fixedly installed on the other end of the inner rod 38. A return spring 381 is sleeved on the outer surface of the inner rod 38. When the limiting rod 37 is pulled outward, the inner rod 38 moves outward, and the baffle 382 at one end of the inner rod 38 squeezes the return spring 381. After the mounting frame 3 is pushed back, the limiting rod 37 is released, and the return spring 381 pulls the limiting rod 37 inward.

[0038] Furthermore, a scraper mechanism is provided on the outer surface of the electric heating tube 31, and the outer surface of the electric heating tube 31 is cleaned by the scraper mechanism. The scraper mechanism includes a scraper 34 arranged inside the mounting frame 3, and a plurality of through grooves are opened on the outer surface of the scraper 34, and the scraper 34 is sleeved on the outer surface of the electric heating tube 31 through the through grooves, and an inner ring 35 is fixedly installed on the inner wall of the through groove.

[0039] The specific implementation method is as follows: when ventilation is performed, fresh air is first introduced into the internal filtering system through the fan 11 at the top to filter the particles in the air, and then enters the temperature control component to adjust the air temperature. The regulated air is output from the exhaust pipe 23 and transported to the room for air circulation. The temperature control component heats the electric heating tube 31 through the internal resistance wire to increase the temperature of the air. When the electric heating tube 31 needs to be cleaned, the limit blocks 37 on both sides of the mounting frame 3 are first pulled outward to disengage one end of the limit block 37 from the limit groove 13 at one end of the first slide groove 12, the limit on the mounting frame 3 is released, and then the mounting frame 3 is pulled outward, and then the front of the mounting frame 3 is rotated. The turntable 32 at the end drives the screw 33 to rotate, and the screw 33 is threadedly connected with the scraper 34, driving the scraper 34 to move.

After the mounting bracket 3 is pushed back, the limit rod 37 is released, and the reset spring 381 will pull the limit rod 37 inward and insert it into the limit groove 13, so as to continue to limit and fix the mounting bracket 3.

[0040] according to Figure 6-7 A fresh air system for a digital industrial park is shown, wherein a water tank 2 is installed at the bottom of the body 1, and a conveying component is fixedly installed at the top of the water tank 2, through which water mist is conveyed;

[0041] Furthermore, the conveying component includes a branch pipe 21 fixedly installed on the top of the water tank 2, an air pump 24 is fixedly installed on the top of the branch pipe 21, a connecting pipe 22 is fixedly installed on one side of the branch pipe 21, an exhaust pipe 23 is fixedly installed on one end of the connecting pipe 22, and one end of the exhaust pipe 23 is connected to the interior of the body 1. When ventilation is performed, fresh air is first introduced into the internal filtration system through the fan 11 at the top to filter particles in the air, and then enters the temperature control component to adjust the air temperature, and the regulated air is output from the exhaust pipe 23.

[0042] Furthermore, an atomizing tube 27 is provided inside the connecting tube 22, an outer ring 28 is sleeved on the outer surface of the connecting tube 22, a second slide groove 281 is opened on the outer surface of the connecting tube 22, a slider 282 is fixedly installed on the inner wall of the outer ring 28, and the slider 282 is slidably connected to the connecting tube 22 through the second slide groove 281, one end of the slider 282 is fixedly connected to the outer surface of the atomizing tube 27, the air pump 24 is started, the clean water in the water tank 2 is pumped out, atomized through the atomizing tube 27, and the atomized water mist is sprayed into the exhaust pipe 23, so that the air drives the water mist into the room.

[0043] Furthermore, the outer surface of the connecting tube 22 is located on one side of the outer ring 28 and is sleeved with a first electromagnet 25, and the outer surface of the connecting tube 22 is located on the other side of the outer ring 28 and is sleeved with a second electromagnet 26. When the adjustment is completed, the first electromagnet 25 is turned off, and the second electromagnet 26 on the other side is started, driving the outer ring 28 to reset along the second slide groove 281, so as to move the internal atomizing tube 27, so that one end of the atomizing tube 27 is separated from the exhaust pipe 23, and the atomizing tube 27 is closed to stop the water mist from being delivered.

[0044] The atomizing tube 27 is a cylindrical tube body, a first spraying area is arranged on the axial circumference of the tube body of the cylindrical atomizing tube 27, and a second spraying area is arranged on the radial circumference of the tube body of the cylindrical atomizing tube 27. A plurality of spray holes are distributed in the first and second spraying areas, and the number of the spray holes in the first spraying area and the second spraying area are different. The first spraying area and the second spraying area are both arranged at the end of the tube body of the cylindrical atomizing tube 27 close to the exhaust pipe 23. The plurality of first spray holes in the first spraying area are in a ring shape, and the plurality of second spray holes in the second spraying area are in a circle shape. A first shielding mechanism and a second shielding mechanism are arranged in the first spraying area and the second spraying area. The temperature output value of the temperature sensor of the temperature control component and the external humidity value form a two-dimensional coordinate. In response to the position of the two-dimensional coordinates of the temperature output value of the temperature sensor of the temperature control component and the external humidity value in the rectangular coordinate system, the opening of the first shielding mechanism and the second shielding mechanism and the opening of the first electromagnet 25 and the second electromagnet 26 are controlled.

[0045] This design makes it possible to match the best working curve according to the temperature and humidity data, making the user more comfortable while reducing the extended space occupied on the air flow channel.

[0046] The specific working process of the present invention is as follows: Figure 1-5When ventilation is performed, fresh air is first introduced into the internal filtering system through the fan 11 at the top to filter the particles in the air, and then enters the temperature control component to adjust the air temperature. The regulated air is output from the exhaust pipe 23 and transported to the room for air circulation. The temperature control component heats the electric heating tube 31 through the internal resistance wire to adjust the temperature of the air. When the electric heating tube 31 needs to be cleaned, the limit blocks 37 on both sides of the mounting frame 3 are first pulled outward to disengage one end of the limit block 37 from the limit groove 13 at one end of the first slide groove 12, and the limit on the mounting frame 3 is released, and then the mounting frame 3 is pulled outward, and then the turntable 32 at the front end of the mounting frame 3 is rotated to drive the screw 33 to rotate. The screw 33 is threadedly connected with the scraper 34, which drives the scraper 34 to move, and the dust on the surface of the electric heating tube 31 is cleaned by closing the inner ring 35 on the inside;

[0047] If the current humidity value is very low and the temperature value is also relatively low, the first electromagnet 25 is started at this time, the outer ring 28 is attracted by the magnetic force of the first electromagnet 25, the inner ring 35 slides along the first slide groove 12 on the connecting pipe 22, and the internal atomizing tube 27 is driven to move through the slider 282, so that the end of the atomizing tube 27 provided with the second spray area is just inserted into the exhaust pipe 23, and the first shielding mechanism is controlled to open all the spray holes on the first spray area, and the second shielding mechanism is controlled to open all the spray holes on the second spray area, and the air pump 24 is started to pump out the clean water in the water tank 2, and atomize it through the atomizing tube 27, and the atomized water mist is sprayed into the exhaust pipe 23, so that when the high-temperature airflow is output from the exhaust pipe 23, the high-humidity water mist is also output from the exhaust pipe 23 at the same time. The first electromagnet 25 is injected at the edge of the tube 23, thereby outputting a high-temperature and high-humidity airflow. After working for a certain period of time, the first electromagnet 25 is closed, and the second electromagnet 26 on the other side is started, driving the outer ring 28 to reset along the second slide groove 281, thereby moving the internal atomizing tube 27, so that one end of the atomizing tube 27 is detached from the exhaust pipe 23, and the atomizing tube 27 is closed. Then the alternating opening operation of the first electromagnet 25 and the second electromagnet 26 is cyclically performed, and the first shielding mechanism and the second shielding mechanism are alternately shielded during the alternating process, so that only the first spray area and the second spray area are alternately opened, so that the humidity adjustment value can change with more gradients, and the number of spray holes in the first spray area and the second spray area is different, thereby having a richer humidity adjustment gradient.

[0048] In addition, if the humidity is close to the appropriate range and the temperature needs to be significantly adjusted, it is only necessary to control the first shielding mechanism and the second shielding mechanism in the opening adjustment stage so that only the first spray area is opened and the second spray area is closed.

[0049] The first shielding mechanism and the second shielding mechanism in the above process can adopt conventional sliding rings with through holes that can move forward and backward and discs with through holes that can be electrically driven to rotate, so that shielding and opening operations can be performed relative to the through holes on the first spray area and the second spray area.

[0050] In addition, if humidity adjustment is not required and the temperature only needs to be adjusted in a small range to reach a suitable value, the first electromagnet 25 can be started, the outer ring 28 is attracted by the magnetic force of the first electromagnet 25, and the inner ring 35 slides along the first slide groove 12 on the connecting pipe 22, and the internal atomizing tube 27 is driven to move by the slider 282, so that the end of the atomizing tube 27 provided with the second spray area is just inserted into the exhaust pipe 23, and the first shielding mechanism is controlled to open all the spray holes on the first spray area, and the air pump 24 is kept closed, so that the through holes on the first spray area at this time serve as the flow path of the high-temperature airflow, and no water mist is sprayed out, thereby providing a high-temperature airflow with a lower flow rate.

[0051] If humidity adjustment is not required, but the temperature still needs to be adjusted to a greater extent to reach an appropriate value, the exhaust pipe 23 can be opened at this time so that the two electromagnets can control the atomization pipe 27 so that it does not extend into the exhaust pipe 23, allowing the high-temperature airflow to circulate quickly.

[0052] The controllable extension and insertion of the atomizer tube 27 in the exhaust pipe 23 means that the humidity adjustment module in the present application does not need to be fixed in the series flow channel, so that the occupied space is greatly reduced, and the extension and insertion design can be used for rapid adjustment of different modes, making the control more precise, the gradient richer, and the user more comfortable.

[0053] In the above process, the present invention sets up linked temperature control components and adjustment components, which can be connected in series in a non-traditional way in terms of spatial layout, so that the entire occupied space is smaller, and can be matched and combined for adjustment, so that it can work in more working modes, so that the use application scenarios increase the comfort and occupy a smaller series extension space.
