[0034] like Figure 1-Figure 7As shown, the power box 1 is used to install electrical components, controllers and other parts. The power box 1 is a prior art and will not be described in detail. By setting up a dehumidifier, moisture can be dehumidified and filtered when the dehumidifier is working. The chassis 2 is used to seal and install semiconductor thermoelectric plates 9, fan blades 7, baffles 8 and other parts. When the semiconductor thermoelectric plates 9 are working, a hot and cold temperature difference can be formed on the two end faces of the semiconductor. When moisture passes through the cold surface of the semiconductor thermoelectric plates 9, the moisture in the air can condense into water droplets, thereby dehumidifying the air. The semiconductor thermoelectric plates 9 are a prior art and will not be described in detail. When the fan blades 7 rotate and work, multiple baffles 8 can be moved outward while rotating and opening, so that the air inlet of the chassis 2 is Open, after the air inlet is opened, the fan blades 7 can suck the outside air into the chassis 2, and blow it out from the air outlet 4 of the chassis 2 into the power box 1. When the air enters the inside of the chassis 2, it will meet the semiconductor thermoelectric plate 9, which can condense the moisture in the air into water droplets and flow to the designated position, thereby removing the moisture in the power box 1 to prevent moisture from causing electrical failures; under normal circumstances, the baffle 8 can be unfolded in a co-linear state, and the air inlet of the chassis 2 can be sealed. When the dehumidifier is not working, the entry of gas can be reduced, the entry of moisture can be reduced, and the working cycle of the dehumidifier can be extended; a filter plate 3 is also provided on one side end face of the chassis 2, and the filter plate 3 can prevent garbage from entering and being sucked into the chassis 2.

The inner wall of the chassis 2 is also fixedly connected to a vertical plate 10, and the drive shaft 6 is rotatably connected to the vertical plate 10. The fan blade 7 is fixedly connected to one side end face of the drive shaft 6.

[0036] like Figure 4 As shown, the function of the first motor 5 is to provide rotational force for the drive shaft 6 and the fan blades 7. The motor 5 is a prior art and will not be described in detail. The vertical plate 10 supports and limits the drive shaft 6 and other components, so that the drive shaft 6 can rotate stably. When the first motor 5 is started, it can drive the corresponding drive shaft 6 and fan blades 7 to rotate. When the fan blades 7 rotate, the dehumidifier will work.

[0037] The chassis 2 is provided with horizontal plates 23 capable of moving forward and backward on both sides of the inner wall at the bottom end, and the first spur racks 26 are fixedly connected to the outer sides of the front end surfaces of the two horizontal plates 23, and the first spur gears 25 are meshed with the inner ends of the first spur racks 26, and the lower ends of the first spur gears 25 are rotatably connected to the fixed sliders 24, and the first spur racks 26 are slidably connected to the upper end surfaces of the fixed sliders 24, and the inner sides of the two fixed sliders 24 are respectively provided with a plurality of movable sliders 34 slidably connected to the chassis 2, and the upper ends of the movable sliders 34 are rotatably connected to the second spur gears 33, and the outer surfaces of the second spur gears 33 are meshed with second spur racks 32 slidably connected to the movable sliders 34, and the second spur racks 32 are slidably connected to the corresponding horizontal plates 23, and the baffles 8 are coaxially fixed to the corresponding upper ends of the first spur gears 25 and the second spur gears 33.

[0038] like Figure 10-12 As shown, the air inlet of the chassis 2 is the front end, and the air outlet of the chassis 2 is the rear end. The movable slider 34 can be slidably connected to the inner wall of the chassis 2 left and right. The inner walls at the centers of the first spur gear 25 and the second spur gear 33 are respectively fixed with rotating shafts, and the rotating shafts are respectively rotatably connected to the corresponding fixed slider 24 and the movable slider 34, and the baffles 8 are respectively fixed to the upper end surfaces of the rotating shafts; the fixed sliders 24 are respectively fixed to the inner walls of the bottom end of the chassis 2, and the fixed sliders 24 can limit the support of the first straight rack 26, the first straight gear 25, the corresponding baffle 8, etc., and the first straight rack 26 is respectively slidably connected to the upper end surfaces of the corresponding fixed sliders 24 front and back, that is, the first straight rack 26 can only move back and forth on the corresponding fixed slider 24, and the rear ends of the first straight rack 26 are respectively fixed to the cross plate 23, that is, when the cross plate 23 moves back and forth, the first straight rack 26 can be driven to move back and forth, and the second straight rack 32 is respectively slidably connected to the first On the front end surface of the two cross plates 23, the second spur racks 32 are respectively connected to the upper end surfaces of the corresponding movable slide blocks 34 by sliding forward and backward. When the movable slide blocks 34 move left and right, they can drive the corresponding second spur racks 32 and the second spur gears 33 to move synchronously. When the cross plate 23 moves forward and backward, they can drive the corresponding first spur racks 26 and the second spur gears 32 to move forward and backward synchronously. When the cross plate 23 moves forward and backward, they can drive the corresponding first spur racks 26 and the second spur gears 32 to move forward and backward synchronously. When the multiple movable slide blocks 34 move left and right, that is, move inward to expand or move outward to close, they can drive the corresponding baffle 8 to move inward to expand or move outward to close. When the cross plate 23 moves forward and backward, it can drive the corresponding first spur racks 26 and the second spur racks 32 to move forward or backward synchronously. When the first spur racks 26 and the second spur racks 32 move forward or backward, they will be meshed with the first spur gears 25 and the second spur gears 33, and the baffle 8 will rotate.

[0039] The upper ends of the first spur gears 25 are rotatably connected to active rods 27, and the upper ends of the second spur gears 33 are rotatably connected to connecting rod groups, which are hinged to the active rods 27. Extension rods 28 are respectively provided at the outer ends of the two active rods 27, and long key grooves 30 are respectively opened on the inner walls of the extension rods 28. The upper end surfaces of the first spur racks 26 are respectively fixed with first sliding pins 29 that match the long key grooves 30.

[0040] like Figure 10-11 As shown, the connecting rod group includes two long connecting rods 31 and a driven rod 35, the two long connecting rods 31 and the driven rod 35 are respectively rotatably connected to the corresponding rotating shafts, the two long connecting rods 31 and the driven rod 35 are hinged at the head and tail ends, the active rod 27 is respectively hinged on a corresponding long connecting rod 31, and the active rod 27, the driven rod 35, the long connecting rod 31, and the extension rod 28 are installed and shaped as shown in FIG. Fig.11 As shown, through the meshing of the first sliding pin 29 and the long key groove 30, when the first straight rack 26 moves forward or backward, it can drive the corresponding active rod 27 to flip. When the active rod 27 flips, it will drive the corresponding second spur gear 33, the second spur rack 32, the movable slide block 34, the baffle plate 8, etc. to move inward or outward through the hinge connection with the long connecting rod 31, and always keep the equidistant inward or outward movement. Therefore, when the cross plate 23 moves forward, it can drive the corresponding first straight rack 26, the second spur rack 32, etc. to move forward synchronously. When the first straight rack 26 and the second spur rack 32 move forward, Then the corresponding baffle 8 will be driven to rotate, and the first straight rack 26 moving forward can drive the first sliding pin 29 to move forward. When the first sliding pin 29 moves forward, it can drive the baffle 8 to move to both sides and close, so that the baffle 8 moves outward and closes while rotating. When the cross plate 23 moves forward to the top position, the corresponding baffle 8 can move to the outermost end position, and the baffle 8 can rotate 90 degrees to be perpendicular to the chassis 2. At this time, the air inlet is in a fully open state; when the cross plate 23 moves backward, it can drive the baffle 8 to move inward, expand and rotate to a state parallel to the chassis 2. At this time, the air inlet is closed and no further explanation will be given.

[0041] Two short guide rods 17 are fixedly connected to the rear end surface of the vertical plate 10, and a driving plate 16 that can move forward and backward is slidably connected to the outer surface of the two short guide rods 17. A cross bar 19 is slidably connected to the inner wall of the lower end of the driving plate 16, and a U-shaped push plate 20 that cooperates with the cross bar 19 is slidably connected to the inner wall of the bottom end of the chassis 2. The cross plate 23 is respectively fixed to both sides of the front end surface of the U-shaped push plate 20, and a stopper 21 is also fixed to the inner wall of the bottom end of the chassis 2. The rear end surface of the stopper 21 is fixed to a first spring 22, and the rear end of the first spring 22 is fixed to the U-shaped push plate 20.

[0042] like Figure 8-Figure 10As shown, the short guide rod 17 can limit the driving plate 16 to move forward and backward, and the rear end surface of the short guide rod 17 is also fixed with an anti-slip pad 18, which can prevent the driving plate 16 from being separated from the short guide rod 17; the cross bar 19 can be slidably connected to the inner wall of the driving plate 16 up and down, and when the driving plate 16 moves forward and backward, it can drive the cross bar 19 to move up and down, and the cross bar 19 can move up and down on the inner wall of the driving plate 16; the U-shaped push plate 20 can slide back and forth on the inner wall of the bottom end of the chassis 2, and the stop pad 21, the first spring 22, the U-shaped push plate 20, and the cross bar 19 are installed and shaped as shown in the figure. Fig.10 As shown, the first spring 22 always has a backward thrust on the U-shaped push plate 20, so that the U-shaped push plate 20 is in the rearmost position under normal conditions. The U-shaped push plate 20 is fixedly connected to the cross plate 23, and can drive the cross plate 23 to move forward and backward when the U-shaped push plate 20 moves forward and backward. Under the elastic force of the first spring 22 itself, the cross plate 23 can be driven to be in the rearmost position under normal conditions, that is, the corresponding baffle 8 is in a colinear unfolded state under normal conditions, that is, the air inlet is sealed; the cross bar 19 is at the lowermost position of the driving plate 16 under its own gravity and normal conditions. When the driving plate 16 moves forward, it can drive the cross bar 19 and the U-shaped push plate 20 to move forward. When the U-shaped push plate 20 moves forward, it will compress the first spring 22. When the U-shaped push plate 20 moves forward, it will drive the cross plate 23 to move forward, the baffle 8 moves outward, closes and rotates, so that the air inlet is opened.

[0043] A first circular ring 11 is fixedly connected to the rear end of the outer surface of the driving shaft 6, and a plurality of evenly distributed first connecting rods 12 are hinged on the outer surface of the first circular ring 11. Centrifugal balls 13 are respectively fixed to the outer ends of the first connecting rods 12. A connecting disk 15 slidably connected to the driving shaft 6 is rotatably connected to the driving plate 16. A first tension spring 52 is fixedly connected to the middle of the rear end surface of the connecting disk 15. The rear end of the first tension spring 52 is fixed to the first circular ring 11. A plurality of distributed second connecting rods 14 are also hinged at the non-center of the rear end surface of the connecting disk 15. The rear ends of the second connecting rods 14 are respectively hinged to the corresponding first connecting rods 12.

When the connecting disk 15 moves back and forth, the drive plate 16 can move back and forth. The first tension spring 52 always has a backward pulling force on the drive plate 16, so that the drive plate 16 is in the rearmost position under normal conditions; when the drive shaft 6 rotates, it can drive the first ring 11 to rotate, and when the first ring 11 rotates, it can drive the first connecting rod 12 and the centrifugal ball 13 to move in a circle. When the centrifugal ball 13 moves in a circle, it drives the first connecting rod 1 under the action of centrifugal force. 2 flips forward, when the first connecting rod 12 flips forward, it can drive the second connecting rod 14 to move forward, and when the second connecting rod 14 moves forward, it can drive the connecting plate 15 and the driving plate 16 to move forward. When the driving plate 16 moves forward, it will drive the corresponding cross bar 19 and the U-shaped push plate 20 to move forward, so that the baffle 8 is opened. When the driving shaft 6 stops rotating, that is, when the fan blade 7 stops working, the corresponding first ring 11 and the centrifugal ball 13 no longer rotate. At this time, the connecting plate 15, the driving plate 16 and the cross bar 19 will move backward and reset under the tension of the first tension spring 52, that is, the centrifugal ball 13 swings backward and resets to the initial state, and the U-shaped push plate 20 will reset to the initial state under the elastic force of the first spring 22, which will not be repeated.

[0045] A detachable recovery box 46 is provided at the lower end of the chassis 2 , and the semiconductor thermoelectric plate 9 is arranged obliquely, with one end of the semiconductor thermoelectric plate 9 corresponding to the air outlet 4 , and the other end of the semiconductor thermoelectric plate 9 corresponding to the recovery box 46 .

A rectangular hole 39 that cooperates with the float rod 36 is opened on the cross bar 19. Wing plates 38 that cooperate with the float rod 36 are respectively fixedly connected to the left and right end surfaces of the float rod 36. An alarm device that cooperates with the cross bar 19 is provided at the front end of the vertical plate 10.

A certain width is provided on the left and right ends of the square hole so that the wing plate 38 can pass through the inner wall of the square hole when moving up and down, that is, to prevent the wing plate 38 from moving against the square hole. The float rod 36 can slide up and down on the inner wall of the bottom end of the chassis 2, and the float ball 37 is arranged in the recovery box 46. When the recovery box 46 is filled with water, the float rod 36 and the float ball 37 can be driven to move upward under the buoyancy of the water; through the rectangular hole 39 provided, the float rod 36 can move up and down on the inner wall of the rectangular hole 39, and the cross bar 19 can move forward and backward, and the movement of the float rod 36 and the cross bar 19 does not affect each other; when the water level line in the recovery box 46 continues to rise to a certain height , which can drive the float 37, the float rod 36, and the wing plate 38 to move upward. When the wing plate 38 moves upward and contacts with the cross bar 19, the wing plate 38 continues to move upward and will drive the corresponding cross bar 19 to move upward. When the wing plate 38 and the cross bar 19 move upward to the specified position, that is, the cross bar 19 is out of contact with the U-shaped push plate 20, the U-shaped push plate 20 is no longer driven to move forward. The U-shaped push plate 20 can move backward and reset under the elastic force of the first spring 22, that is, the baffle 8 flips to the horizontal state and resets, so that the air inlet is closed to reduce the entry of outside air. When the cross bar 19 moves upward, it will drive the alarm device to work. The water level in the recovery box 46 is too high, which can remind the user that the recovery box 46 needs to be replaced to prevent excessive water in the recovery box 46 from overflowing.

[0049] The alarm device includes a support plate 43 slidably connected to the vertical plate 10, a sounding plate 44 is fixedly connected to the upper end surface of the support plate 43, a ball bell 45 matched with the sounding plate 44 is fixedly connected to the outer surface of the driving shaft 6, a long guide rod 40 matched with the cross bar 19 is fixedly connected to the lower end surface of the support plate 43, a spring seat 41 is also fixedly connected to the lower side of the front end surface of the vertical plate 10, the long guide rod 40 is slidably connected to the inner wall of the spring seat 41, a second tension spring 42 is fixedly connected to the spring seat 41, and the upper end of the second tension spring 42 is fixedly connected to the support plate 43.

[0050] like Fig.15As shown, the support plate 43 can slide up and down on the front end surface of the vertical plate 10, and the spring seat 41 supports and limits the second tension spring 42. The second tension spring 42 always has a downward pulling force on the support plate 43, so that the support plate 43 and the sound plate 44 are in the lowest state under normal conditions. The sound plate 44 has a certain elasticity and can swing left and right, and can produce a sound when the ball bell 45 hits the sound plate 44. When the drive shaft 6 is working, it can dehumidify the moisture in the air, and drive the ball bell 45 to rotate, which will collect the moisture in the recovery box 46. When the water in the recovery box 46 reaches When the wing plate 38 is in the designated position, it contacts the cross bar 19 and moves upward, the cross bar 19 can push the long guide rod 40 to move upward, and the long guide rod 40 can drive the support plate 43 and the sound plate 44 to move upward. After the sound plate 44 moves upward to the designated position, that is, it moves to contact the ball bell 45, and the ball bell 45 rotates and continuously hits the sound plate 44. At this time, an alarm sound can be generated, thereby reminding the user to clean the water in the recovery box 46, and when the alarm is triggered, the baffle 8 can be reset to close the air inlet, reduce air entry, and prevent water in the recovery box 46 from overflowing.

[0051] Square tubes 51 are fixedly connected to the left and right sides of the lower end surface of the chassis 2, and square latch pins 47 are slidably connected to the inner walls of the square tubes 51. Square latch grooves matching the square latch pins 47 are respectively provided on the left and right end surfaces of the recovery box 46. Square blocking pieces 48 are fixedly connected to the outer surfaces of the square latch pins 47. Small springs 49 matching the square blocking pieces 48 are respectively provided on the inner walls of the square tubes 51, and pull rings 50 are respectively fixedly connected to the outer end surfaces of the square latch pins 47.

[0052] like Figure 16-Figure 17 As shown, the pull ring 50 can move left and right, that is, it drives the square latch pin 47 to move left and right, and the square baffle 48 can be slidably connected to the inner wall of the square tube 51 left and right. The small spring 49 can have an inward driving force on the square baffle 48, so that the square latch pin 47 is at the innermost end under normal conditions, that is, the square latch pin 47 is stably engaged with the square latch groove. When the square latch pin 47 is engaged with the square latch groove, the collection box can be fixed. When the collection box needs to be disassembled, by driving the two pull rings 50 to move outward, the square latch pin 47 can be driven to move outward and disengage from the square latch groove. At this time, the collection box can be disassembled and replaced.

[0053] When the present invention is in use, when the fan blades 7 rotate and work, multiple baffles 8 can be moved outward and rotated to open, so that the air inlet of the chassis 2 is opened. After the air inlet is opened, the fan blades 7 can suck the outside air into the chassis 2, and blow it out from the air outlet 4 of the chassis 2 into the power box 1. When the air enters the inside of the chassis 2, it will meet the semiconductor thermoelectric plate 9, which can condense the moisture in the air into water droplets and flow to the designated position, thereby removing the moisture in the power box 1 and preventing electrical faults caused by moisture; under normal conditions, the baffles 8 can be unfolded and in a co-linear state, and the air inlet of the chassis 2 can be sealed. When the dehumidifier is not working, the entry of gas can be reduced, the entry of moisture can be reduced, and the working cycle of the dehumidifier can be extended.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
