DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4 , the utility model provides an embodiment: a combined closed heat exchanger unit, including a base 1, a hollow box 3 is fixedly connected to the top of the base 1, baffles 4 are fixedly connected to the left and right sides of the interior of the hollow box 3, a filter plate 5 is arranged in the middle of one side of the baffle 4, a cavity 6 is opened inside the baffle 4, a movable shaft 7 is rotatably connected to one side of the baffle 4, one end of the movable shaft 7 passes through the cavity 6 and is fixedly connected to an active bevel gear 8, a bidirectional screw rod 9 is rotatably connected to the interior of the cavity 6, a driven bevel gear 10 is fixedly connected to the middle of the outer side of the bidirectional screw rod 9, two active bevel gears 8 are respectively meshed and connected with the corresponding driven bevel gears 10, the front and rear sides of the outer walls of the two bidirectional screw rods 9 are threadedly connected with movable blocks 11, the top of the movable block 11 is fixedly connected with a limiting rod 12, one end of the plurality of limiting rods 12 respectively passes through the front and rear sides of the corresponding filter plates 5, the plurality of movable blocks 11 are respectively slidably connected to the corresponding interior of the cavity 6, and an adjustment mechanism 2 is arranged on the right side of the interior of the hollow box 3;

[0033] Specifically, when the movable shaft 7 is rotated, the driving bevel gear 8 will rotate accordingly. Since there is a precise meshing relationship between the driven bevel gear 10 and the driving bevel gear 8, the driven bevel gear 10 will rotate along with the rotation of the driving bevel gear 8. As the driven bevel gear 10 rotates, it will further drive the bidirectional screw 9 connected thereto to rotate. During the rotation of the bidirectional screw 9, the movable block 11 on its outer side will be displaced accordingly, and the limiting rod 12 on its top will also move to both sides accordingly, thereby releasing the limiting fixation of the filter plate 5. In this way, it is relatively simple to disassemble and replace the filter plate 5, thereby reducing the workload of the staff.

[0034] Reference Figure 2 and Figure 5The adjusting mechanism 2 includes a servo motor 201, which is fixedly connected to the right end of the top inner side of the hollow box 3, and a worm 202 is fixedly connected to the output end of the servo motor 201. A cross fixing plate 203 is fixedly connected to the right inner side of the hollow box 3, and a rotating rod 204 is rotatably connected to the left side of the cross fixing plate 203. The outer sides of the rotating rod 204 are fixedly connected to sector plates 205, and the outer side of the rotating rod 204 is fixedly connected to a worm gear 206, which is meshed with the worm 202, and the gap sizes on the cross fixing plate 203 match the corresponding sizes of the sector plates 205;

[0035] Specifically, the servo motor 201 can drive the worm 202 to rotate. Since the worm wheel 206 and the worm 202 are meshed with each other, when the worm 202 rotates, the worm wheel 206 will also rotate. As the worm wheel 206 rotates, the fan plate 205 also starts to move accordingly. The change in angle between the fan plate 205 and the cross fixing plate 203 directly determines the size of the air output. When the air output needs to be increased, the servo motor 201 rotates forward, so that the angle between the fan plate 205 and the cross fixing plate 203 increases, thereby increasing the area of ​​the air outlet and increasing the air output; conversely, when the air output needs to be reduced, the servo motor 201 rotates in the reverse direction, so that the angle between the fan plate 205 and the cross fixing plate 203 decreases, thereby reducing the area of ​​the air outlet and reducing the air output, thereby achieving precise adjustment of the air output, achieving the purpose of optimizing energy efficiency, accurately controlling temperature and reducing energy waste.

[0036] Reference Figure 1 and Figure 2 A fan 13 is fixedly connected to the middle of the inner bottom end of the hollow box 3, an outlet pipe 14 is connected to the output end of the fan 13, an exhaust pipe 15 is connected to the input end of the fan 13, a full heat exchange core 16 is fixedly connected to the left side of the inside of the hollow box 3, an opening groove 17 is opened on the left side of the front end of the base 1, and a connecting pipe 18 is connected to the left side of the bottom of the hollow box 3, and the middle and lower part of the connecting pipe 18 passes through the opening groove 17 and is provided with an electric valve 19;

[0037] Specifically, the fan 13 can be used to conveniently recycle the dirty air and the fresh air, and the provided full heat exchange core 16 can perform heat exchange processing on the gas drawn in by the fan 13, thereby facilitating the heat exchange work.

[0038] Reference Figure 1 A plurality of doors 20 are equidistantly arranged on the front side of the hollow box 3, and hinges 21 are arranged on the upper and lower sides of the front ends of the plurality of doors 20. The plurality of doors 20 are rotatably connected to the front side of the hollow box 3 through the hinges 21, and a handle 22 is rotatably connected to the front side of the door 20. An observation window 23 is arranged in the middle of the front end of the door 20;

[0039] Specifically, the box door 20 can be opened by the handle 22, and the internal structure of the hollow box 3 can be easily inspected and maintained. The observation window 23 can be arranged to facilitate the staff to check the internal situation of the hollow box 3 at any time.

[0040] Reference Figure 1 A controller 24 is fixedly connected to the middle upper part of the front end of the middle door 20. The controller 24 is electrically connected to the servo motor 201, the fan 13 and the electric valve 19 respectively. A protective cover 25 is arranged on the outside of the controller 24. One side of the protective cover 25 is rotatably connected to the front side of the corresponding door 20.

[0041] Specifically, the operation of the servo motor 201, the fan 13 and the electric valve 19 can be controlled by the controller 24, and the protective cover 25 can protect the controller 24 from being damaged by external factors.

[0042] Working principle: When using the unit, the indoor dirty air is first drawn into the hollow box 3 through the fan 13. At this time, the dirty air will pass through the two filter plates 5 in turn and enter the left side of the hollow box 3. Then a part of the dirty air will be absorbed by the full heat exchange core 16 and converted into hot air. Then the electric valve 19 is opened. At this time, the fresh air from the outside will enter the hollow box 3. Then the mixed air generated by the fresh air and the hot air is discharged into the room through the fan 13. After long-term use, the filter plate 5 is easily blocked by impurities. At this time, the movable shaft 7 is rotated, and the active bevel gear 8 will rotate accordingly. The driven bevel gear 10 will rotate along with it due to the meshing with the active bevel gear 8, thereby driving the bidirectional screw rod 9 to rotate. At this time, the bidirectional screw rod 9 The movable block 11 on the outside of the rod 9 will drive the limit rod 12 to move to both sides so that the limit fixation of the filter plate 5 can be released. It is relatively simple to disassemble and replace the filter plate 5, thereby reducing the workload of the staff and meeting the needs of the users. When fresh air is injected into the room, the servo motor 201 can drive the worm 202 to rotate, and the worm wheel 206 will rotate accordingly due to the engagement with the worm 202, thereby driving the fan plate 205 to rotate. At this time, the air outlet can be adjusted according to the angle change between the fan plate 205 and the cross fixing plate 203, thereby achieving energy efficiency optimization, precise temperature control and reduction of energy waste, thereby improving the practicality of the device.
