[0041] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0042] 1. The total heat exchanger of the present invention has a scraping component arranged. After the humidity sensor in the total heat exchanger body detects that the humidity value in the total heat exchanger body reaches a predetermined value, it will transmit a signal to the drive motor, so that the output end of the drive motor outputs. After the output end of the drive motor outputs, it can drive the driving wheel to rotate, and at the same time drive the connecting belt to move forward, so as to drive the displacement plate to move forward as a whole. After the displacement plate moves forward, it can drive the first scraping frame to move forward as a whole. Since the first scraping frame and the connecting plate are respectively attached to the four side surfaces of the heat exchange core, the first scraping frame and the connecting plate can scrape water droplets from the heat exchange core as a whole in the front and rear directions. While scraping water droplets from the heat exchange core, a part of the water droplets on the heat exchange core can be pushed toward the edge of the heat exchange core, and finally fall from the edge of the heat exchange core.

[0043] 2. The total heat exchanger of the present invention can drive the displacement rod to move leftward when the displacement plate moves leftward through the arranged buffer member. When the displacement rod penetrates into the buffer box, on the one hand, it can touch the buffer airbag so that the buffer airbag is inflated to flush the outlet plug out of the outlet pipe, and at the same time, the moisture-proof particles in the outlet plug can be flushed out to the bottom of the heat exchange core to absorb water drops falling from the edge of the heat exchange core. On the other hand, the buffer airbag can buffer the leftward movement of the displacement rod to prevent the first scraping frame from completely falling off from the heat exchange core.

[0044] 3. The total heat exchanger of the present invention, through the arranged linkage blowing component, can drive the linkage gear to rotate when the tooth plate moves to the left and when the tooth plate and the linkage gear are in contact and meshing with each other, and then drive the fan blade to rotate, so as to blow air to the total heat exchanger body and move it to the left, so as to accelerate the air drying effect of the water droplets in the total heat exchanger body. Since when the first scraping frame moves to the left to scrape the heat exchange core, the more it moves to the right, the more the water droplets gradually gather and increase. Therefore, when the tooth plate moves from left to right, it first meshes with a group of linkage gears, and then meshes with two groups of linkage gears, combined with meshing with three groups of linkage gears, and finally meshes with four groups of linkage gears, which is equivalent to being able to blow air into the total heat exchanger body in a progressively increasing manner when the tooth plate moves from left to right, so as to cooperate with the situation that when the first scraping frame moves to the left to scrape the heat exchange core, the more the water droplets gradually gather and increase as they move to the right, so as to further increase the blowing effect of the sub-blowing component;

[0045] 4. The total heat exchanger of the present invention, through the arranged heating components, when the humidity sensor in the total heat exchanger body detects that the humidity value in the total heat exchanger body reaches a predetermined value, it will transmit a signal to the first heating tube and the second heating tube to operate. When the temperature of the first heating tube and the second heating tube rises, on the one hand, the temperature of the entire heating frame can be increased, and the water droplets on and off the heat exchange core can be heated and dehumidified by surrounding the through grooves. On the other hand, it can trigger the moisture absorbing component to flip over as a whole, and the moisture absorbing particles in the moisture absorbing component can be flipped and fall into the To the bottom of the heat exchange core, it can further speed up the moisture absorption operation of the water droplets falling from the bottom of the heat exchange core. After the moisture absorbing particles falling from the moisture absorbing component absorb the moisture from the water droplets falling from the bottom of the heat exchange core, it can further reduce the heating and drying time of the first heating tube and the second heating tube as a whole. On the other hand, when the heating frame surrounds the heat exchange core, it can make the hot air heated by it surge upward. When cooperating with the linkage blowing component, it can use the residual heat generated by the heating frame to blow hot air, further speeding up the drying effect of the water droplets on the heat exchange core.

[0046] 5. The total heat exchanger of the present invention has a moisture absorbing component arranged. When the second heating tube is turned on, the temperature increase of the second heating tube can make the expansion airbag expand due to the heat, so that the embedded sheet and the upper moving rod move upward as a whole. When the upper moving rod moves upward as a whole, the balance of the moisture absorbing frame can be broken, so that the moisture absorbing frame is tilted toward one end of the opening, and then the moisture absorbing particles in the moisture absorbing frame are released and fall to the bottom of the heat exchange core to absorb moisture from the bottom of the heat exchange core. When the moisture absorbing frame releases the moisture absorbing particles to the bottom of the heat exchange core, it can also be linked with the scraping component. When the first scraping frame moves forward, it can also push and spread the moisture absorbing particles released from the moisture absorbing frame to further enhance the moisture absorbing effect of the moisture absorbing particles released from the moisture absorbing frame.

[0064] In the embodiment, Figure 1-13 A total heat exchanger is provided, characterized in that it includes a total heat exchanger body 1, which has a heat exchange cavity therein, a first air inlet cover 11 and a second air exhaust cover 14 are detachably arranged on one side of the total heat exchanger body 1, and the first air inlet cover 11 and the second air exhaust cover 14 are both connected to the heat exchange cavity, a second air inlet cover 12 and a first air exhaust cover 13 are detachably arranged on the other side of the total heat exchanger body 1, and the second air inlet cover 12 and the first air exhaust cover 13 are both connected to the heat exchange cavity, and a first fan 15 and a second fan 16 are detachably arranged in the total heat exchanger body 1. A second fan 17 is provided, and the output end of the first fan 15 can penetrate into the second air inlet cover 12, and the output end of the second fan 17 can penetrate into the second air exhaust cover 14. A first protective cover 16 can be detachably arranged on the first fan 15, and a second protective cover 18 can be detachably arranged on the second fan 17. A humidity sensor is also provided in the heat exchange cavity; a heat exchange core 2 is detachably arranged in the heat exchange cavity of the full heat exchanger body 1, and the heat exchange core 2 is located between the second fan 17 and the first fan 15; used to scrape the heat exchange core 2 The scraping member 3 for wiping is detachably arranged in the heat exchange cavity of the total heat exchanger body 1, and the scraping member 3 can cover the side surface of the heat exchange core 2; the buffer member 4 for buffering the scraping member 3 is detachably installed on the inner wall surface of the total heat exchanger body 1, and the buffer member 4 is located on one side of the scraping member 3; the linkage blowing member 5 is detachably arranged on the inner wall surface of the total heat exchanger body 1, and is located on the upper part of the scraping member 3, and can be linked with the scraping member 3 when it moves, and when the linkage blowing member 5 is linked with the scraping member 3, it can The heat exchange cavity of the heat exchanger body 1 is subjected to air blowing operation; the heating component 6 is detachably arranged in the heat exchange cavity of the full heat exchanger body 1, and can cover the heat exchange core 2; the moisture absorbing component 7 is detachably installed in the heat exchange cavity of the full heat exchanger body 1, and has a plurality of groups of moisture absorbing particles therein, which are in conflict with the heating component 6 and can be triggered when the heating component 6 heats the heat exchange core 2. When the moisture absorbing component 7 is triggered, it can be turned over to pour the moisture absorbing particles therein to the bottom of the heat exchange core 2.

[0065] The present invention is based on an overall idea that, through the arranged scraping member 3, the humidity sensor in the full heat exchanger body 1 will transmit a signal to the drive motor 32 after detecting that the humidity value in the full heat exchanger body 1 reaches a predetermined value, so that the output end of the drive motor 32 can output, and the output end of the drive motor 32 can drive the active wheel 33 to rotate after the output end of the drive motor 32 outputs, and at the same time drive the connecting belt 35 to move forward, so as to drive the displacement plate 37 to move forward as a whole, and after the displacement plate 37 moves forward, it can drive the first scraping frame 39 to move forward as a whole, because the first scraping frame 39 and the connecting plate 391 are respectively in contact with the four side surfaces of the heat exchange core 2, so the first scraping frame 39 and the connecting plate 391 can scrape the heat exchange core 2 as a whole along the The water droplets are scraped off in the front-to-back direction. While scraping off the water droplets on the heat exchange core 2, a part of the water droplets on the heat exchange core 2 can be pushed toward the edge of the heat exchange core 2, and finally fall from the edge of the heat exchange core 2. Through the arranged buffer component 4, when the displacement plate 37 moves to the left, the displacement rod 373 can be driven to move to the left. When the displacement rod 373 penetrates into the buffer box 41, on the one hand, it can touch the buffer airbag 42 so that the buffer airbag 42 inflates to flush the air outlet plug 46 out of the air outlet pipe 45, and at the same time, the moisture-proof particles in the air outlet plug 46 can be flushed out to the bottom of the heat exchange core 2, so as to absorb the water droplets falling from the edge of the heat exchange core 2. On the other hand, the buffer airbag 42 can be used to The leftward movement of the displacement rod 373 can be buffered to prevent the first scraping frame 39 from completely falling off the heat exchange core 2. Through the arranged linkage blowing component 5, when the tooth plate 38 moves to the left and when the tooth plate 38 and the linkage gear 53 are in contact and meshing with each other, the linkage gear 53 can be driven to rotate, thereby driving the fan blade 54 to rotate, so as to blow air to the full heat exchanger body 1 and move it to the left, so as to accelerate the drying effect of the water droplets in the full heat exchanger body 1. When the first scraping frame 39 moves to the left to scrape the heat exchange core 2, the more it moves to the right, the more the water droplets gradually gather. Therefore, when the tooth plate 38 moves from left to right, it first meshes with a group of linkage gears 53, and then meshes with two groups of linkage gears 53. It meshes with the three sets of linkage gears 53, and finally meshes with the four sets of linkage gears 53, which is equivalent to being able to blow air into the full heat exchanger body 1 in a progressively increasing manner when the tooth plate 38 moves from left to right, so as to cooperate with the situation that the water droplets gradually gather and increase as the first scraping frame 39 moves to the left to scrape the heat exchange core 2, so as to further increase the blowing effect of the sub-blowing part. Through the arranged heating component 6, when the humidity sensor in the full heat exchanger body 1 detects that the humidity value in the full heat exchanger body 1 reaches a predetermined value, it will transmit a signal to the first heating tube 63 and the second heating tube 64 to work. When the temperature of the first heating tube 63 and the second heating tube 64 increases, on the one hand, the temperature of the entire heating frame 61 can be increased,By surrounding the through groove 62, the water droplets on and falling from the heat exchange core 2 are heated and dehumidified. On the other hand, the moisture absorbing component 7 can be triggered to flip over as a whole, so that the moisture absorbing particles in the moisture absorbing component 7 can be flipped and fall to the bottom of the heat exchange core 2, which can further speed up the moisture absorption operation of the water droplets falling from the bottom of the heat exchange core 2. After the moisture absorbing particles falling from the moisture absorbing component 7 absorb the water droplets falling from the bottom of the heat exchange core 2, the overall heating and drying time of the first heating tube 63 and the second heating tube 64 can be further reduced. On the other hand, when the heating frame 61 surrounds the heat exchange core 2, the hot air heated by it can surge up. When cooperating with the linked blowing component 5, the waste heat generated by the heating frame 61 can be used to blow hot air, thereby further speeding up the drying effect of the water droplets on the heat exchange core 2. As a result, through the arranged moisture absorption component 7, when the second heating tube 64 is turned on, the temperature increase of the second heating tube 64 can make the expansion airbag 74 expand due to heat, so that the embedded sheet 751 and the upper moving rod 75 move upward as a whole. When the upper moving rod 75 moves upward as a whole, the balance of the moisture absorption machine frame 72 can be broken, so that the moisture absorption machine frame 72 tilts toward one end of the opening, and then the moisture absorption particles in the moisture absorption machine frame 72 are released and fall to the bottom of the heat exchange core 2 to absorb moisture from the bottom of the heat exchange core 2. When the moisture absorption machine frame 72 releases the moisture absorption particles to the bottom of the heat exchange core 2, it can also generate linkage with the scraping component 3. In the process of the first scraping frame 39 moving forward, it can also push and spread the moisture absorption particles released from the moisture absorption machine frame 72 to further enhance the moisture absorption effect of the moisture absorption particles released from the moisture absorption machine frame 72.

[0066] Next, a more specific structure and construction is given to the scraping member 3 as a whole for further explanation. The scraping member 3 includes a connecting substrate 31, which is detachably arranged in the heat exchange cavity of the total heat exchanger body 1, and a driven wheel 34 is detachably arranged at its tail end; a driving motor 32, which is detachably mounted on the connecting substrate 31, and its output end can pass through the connecting substrate 31, and a driving wheel 33 is detachably arranged on its output end, and a connecting belt 35 is removably arranged on the driving wheel 33, and the connecting belt 35 can pass around the driven wheel 34; The slide rail 36 is detachably mounted on the connecting substrate 31 and arranged along the length direction of the connecting substrate 31; the displacement plate 37 has a slider 371 detachably arranged at the bottom thereof and capable of sliding on the slide rail 36, and a clamping plate 372 is detachably mounted at the bottom thereof, and the clamping plate 372 is detachably connected to the connecting belt 35; the displacement rod 373 is detachably mounted on one side of the displacement plate 37 and has a cone thorn head; the tooth plate 38 is detachably mounted on the top of the displacement plate 37; the first scraping frame 39 is detachably arranged on one side of the displacement plate 37;

[0067] Next, the overall use principle of the scraping component 3 is further explained. After the humidity sensor in the full heat exchanger body 1 detects that the humidity value in the full heat exchanger body 1 reaches a predetermined value, it will transmit a signal to the drive motor 32, so that the output end of the drive motor 32 outputs. After the output end of the drive motor 32 outputs, it can drive the active wheel 33 to rotate, and at the same time drive the connecting belt 35 to move forward, so as to drive the displacement plate 37 to move forward as a whole. After the displacement plate 37 moves forward, it can drive the first scraping frame 39 to move forward as a whole. Since the first scraping frame 39 and the connecting plate 391 are respectively in contact with the four side surfaces of the heat exchange core 2, the first scraping frame 39 and the connecting plate 391 can scrape water droplets from the heat exchange core 2 as a whole along the front and rear directions. While scraping water droplets from the heat exchange core 2, a part of the water droplets on the heat exchange core 2 can be pushed toward the edge of the heat exchange core 2, and finally fall from the edge of the heat exchange core 2.

[0068] Next, a more specific structure and construction is given to the first scraping frame 39 as a whole for further explanation. The first scraping frame 39 is formed by splicing two groups of triangular frames, each of which has a notch, and the hypotenuse surfaces of the two groups of triangular frames fit with the two side surfaces of the heat exchange core 2. When the hypotenuse surfaces of the two groups of triangular frames fit with the two side surfaces of the heat exchange core 2, the two side surfaces of the heat exchange core 2 can be covered. A second scraping frame 392 is also detachably installed on the first scraping frame 39. The size of the second scraping frame 392 is the same as that of the first scraping frame 39. The second scraping frame 392 can fit with the other two side surfaces of the heat exchange core 2. When the second scraping frame 392 fits with the other two side surfaces of the heat exchange core 2, the other two side surfaces of the heat exchange core 2 can be covered.

[0069] More specifically, in order to be able to fit together with the four side surfaces of the heat exchange core 2 and to prevent the normal area of ​​the heat exchange core 2 from being affected when covering the four side surfaces of the heat exchange core 2, the first scraping frame 39 is designed to be formed by splicing two groups of triangular frames, and the second scraping frame 392 is designed to be the same size as the first scraping frame 39. At the same time, by designing the two triangular frames in the first scraping frame 39 to be hollow, air circulation in the full heat exchanger body 1 can be provided. When the displacement plate 37 moves forward, the two triangular frames of the first scraping frame 39 can be driven forward to scrape off water droplets on the side surfaces of the heat exchange core 2 through the oblique sides of the two triangular frames.

[0070] Next, the overall structure of the buffer component 4 is given a more specific structure and construction for further explanation. The buffer component 4 includes a buffer box 41, which is detachably mounted on the inner wall surface of the total heat exchanger body 1 and has an opening therein for the displacement rod 373 to pass through; a buffer airbag 42, which is detachably mounted in the buffer box 41 and has a size that matches the size of the buffer box 41; an air inlet pipe 43, which is detachably arranged on the buffer airbag 42 and can pass through the buffer box 41, and has an air inlet plug 44 threadedly connected thereto for closing it; an air outlet pipe 45, which is detachably mounted on the buffer airbag 42 and can pass through the buffer box 41, and has an air outlet plug 46 removably penetrated thereon;

[0071] Next, the overall usage principle of the buffer component 4 is further explained. When the displacement plate 37 moves to the left, it can drive the displacement rod 373 to move to the left. When the displacement rod 373 penetrates into the buffer box 41, on the one hand, it can touch the buffer airbag 42 so that the buffer airbag 42 can inflate to flush the air outlet plug 46 out of the air outlet pipe 45, and at the same time, the moisture-proof particles in the air outlet plug 46 can be flushed out to the bottom of the heat exchange core 2 to absorb water droplets falling from the edge of the heat exchange core 2. On the other hand, the buffer airbag 42 can buffer the left movement of the displacement rod 373 to prevent the first scraper frame 39 from completely falling off from the heat exchange core 2.

[0072] Next, a more specific structure and construction of the linkage blowing member 5 is given as a whole for further explanation. The linkage blowing member 5 includes a connecting bottom plate 51, which is located on the upper part of the scraping member 3. An ear plate 56 is detachably arranged on both sides of the bottom plate 51, and the two sets of ear plates 56 are in contact with the two inner wall surfaces of the total heat exchanger body 1. A first fastening screw 57 and a second fastening screw 58 are rotatably arranged on the ear plate 56, and the first fastening screw 57 and the second fastening screw 58 can penetrate into the inner wall of the total heat exchanger body 1; two sets of bonding plates 55 are detachably installed on the inner wall surface of the total heat exchanger body 1, and a A clamping cavity for the ear plate 56 to pass through, a third fastening screw 59 is rotatably arranged on one group of laminating plates 55, and the third fastening screw 59 can pass through the ear plate 56 and the other group of laminating plates 55 in sequence; multiple groups of sub-blowing parts, all of which are rotatably arranged on the connecting bottom plate 51, and the sub-blowing parts include a linkage rod 52, the linkage rod 52 is rotatably arranged on the connecting bottom plate 51, and a linkage gear 53 and a fan blade 54 are detachably arranged on the linkage rod 52, and the linkage gear 53 is located above the tooth plate 38, and the linkage gear 53 can mesh with the tooth plate 38. When the tooth plate 38 drives the linkage gear 53 to rotate, it can drive the fan blade 54 to perform a blowing operation;

[0073] Next, the overall use principle of the linkage blowing component 5 is further explained. When the tooth plate 38 moves to the left and when the tooth plate 38 and the linkage gear 53 are in contact and meshing with each other, the linkage gear 53 can be driven to rotate, thereby driving the fan blade 54 to rotate, so as to blow air to the full heat exchanger body 1 and move it to the left, so as to accelerate the drying effect of the water droplets in the full heat exchanger body 1. When the first scraping frame 39 moves to the left to scrape the heat exchange core 2, the more it moves to the right, the more water droplets gradually gather, so the tooth plate 38 moves to the left and the linkage gear 53 is driven to rotate, thereby driving the fan blade 54 to rotate, so as to blow air to the full heat exchanger body 1 and move it to the left, so as to accelerate the drying effect of the water droplets in the full heat exchanger body 1. When the plate 38 moves from left to right, it first meshes with a group of interlocking gears 53, and then meshes with two groups of interlocking gears 53, and then meshes with three groups of interlocking gears 53, and finally meshes with four groups of interlocking gears 53, which is equivalent to being able to gradually increase the blowing of the heat exchanger body 1 when the tooth plate 38 moves from left to right, so as to cooperate with the situation that when the first scraping frame 39 moves to the left and scrapes the heat exchange core 2, the water droplets gradually gather and increase as they move to the right, so as to further increase the blowing effect of the sub-blowing component.

[0074] In some embodiments, more specifically, the size of the fan blade 54 is matched with the size of the linkage gear 53 , and the length of the tooth plate 38 is greater than the cross-sectional diameter of the linkage gear 53 .

[0075] Next, a more specific structure and construction is given to the whole of the heating component 6 for further explanation. The heating component 6 includes a heating frame 61, which is detachably arranged in the heat exchange cavity of the total heat exchanger body 1, and has a through groove 62 therein, and the through groove 62 can cover the heat exchange core 2, and there is a built-in cavity in the heating frame 61; two groups of first heating tubes 63, which are detachably arranged in the heating frame 61, and the first heating tubes 63 can be inserted into the built-in cavity of the heating frame 61; a second heating tube 64, which is detachably arranged in the heating frame 61, and the second heating tube 64 can be inserted into the built-in cavity of the heating frame 61;

[0076] Next, the overall use principle of the heating component 6 is further explained. When the humidity sensor in the full heat exchanger body 1 detects that the humidity value in the full heat exchanger body 1 reaches a predetermined value, it will transmit a signal to the first heating tube 63 and the second heating tube 64 to operate. When the temperature of the first heating tube 63 and the second heating tube 64 increases, on the one hand, the overall temperature of the heating frame 61 can be increased, and the water droplets on and falling from the heat exchange core 2 are heated and dehumidified by surrounding the through groove 62. On the other hand, it can trigger the moisture absorbing component 7 to flip over as a whole, so that the moisture absorbing particles in the moisture absorbing component 7 can be removed. Flipping and falling to the bottom of the heat exchange core 2 can further speed up the moisture absorption operation of the water droplets dropped from the bottom of the heat exchange core 2. After the moisture absorbing particles dropped from the moisture absorbing component 7 absorb the water droplets dropped from the bottom of the heat exchange core 2, the overall heating and drying time of the first heating tube 63 and the second heating tube 64 can be further reduced. On the other hand, when the heating frame 61 surrounds the heat exchange core 2, the hot air heated by it can surge upward. When cooperating with the linked blowing component 5, the waste heat generated by the heating frame 61 can be used to blow hot air, thereby further speeding up the drying effect of the water droplets on the heat exchange core 2.

[0077] Next, the moisture absorbing component 7 is given a more specific structure and construction as a whole for further explanation. The moisture absorbing component 7 includes a first support arm 71, which is detachably installed in the heat exchange cavity of the total heat exchanger body 1, and a moisture absorbing machine frame 72 is rotatably arranged on it. A plurality of groups of moisture absorbing particles are arranged in the moisture absorbing machine frame 72, and an opening is provided on one side of the moisture absorbing machine frame 72. The moisture absorbing machine frame 72 can pour the plurality of groups of moisture absorbing particles to the bottom of the heat exchange core 2 through the opening; a second support arm 73, which is detachably arranged on the total heat exchanger body 1, and a plurality of groups of moisture absorbing particles are poured into the bottom of the heat exchange core 2 through the second support arm 73. The heat exchange chamber of the exchanger body 1 has a plate groove therein, and the plate groove can be inserted by the second heating tube 64, and an expansion airbag 74 is detachably arranged in the plate groove; the upper moving rod 75 is slidably arranged in the plate groove of the second supporting arm 73, and an inner embedded sheet 751 is detachably arranged at a tail of the upper moving rod 75, and the inner embedded sheet 751 is in conflict with the expansion airbag 74, and a third supporting arm 76 is detachably arranged on the upper moving rod 75, and the third supporting arm 76 is rotatably connected to the bottom of the moisture absorber frame 72;

[0078] Next, the overall working principle of the moisture absorption component 7 is further explained. When the second heating tube 64 is turned on, the temperature increase of the second heating tube 64 can cause the expansion airbag 74 to expand due to the heat, so that the embedded sheet 751 and the upper moving rod 75 are moved upward as a whole. When the upper moving rod 75 is moved upward as a whole, the balance of the moisture absorption machine frame 72 can be broken, so that the moisture absorption machine frame 72 is tilted toward one end of the opening, and then the moisture absorption particles in the moisture absorption machine frame 72 are released and fall to the bottom of the heat exchange core 2 to absorb moisture from the bottom of the heat exchange core 2. When the moisture absorption machine frame 72 releases the moisture absorption particles to the bottom of the heat exchange core 2, it can also generate linkage with the scraping component 3. In the process of moving forward, the first scraping frame 39 can also push and spread the moisture absorption particles released from the moisture absorption machine frame 72 to further enhance the moisture absorption effect of the moisture absorption particles released from the moisture absorption machine frame 72.

[0079] In some embodiments, in order to enable the inner embedded sheet 751 to return to the initial position and at the same time to make the inner embedded sheet 751 smoother during the upward movement, a stabilizing rod 752 is detachably arranged on the inner embedded sheet 751, and the stabilizing rod 752 can pass through the second support arm 73, and a limiting block 753 is detachably arranged on the end of the stabilizing rod 752 passing through the second support arm 73. In the initial state, the limiting block 753 does not touch the second support arm 73, and a spring 754 is removably sleeved on the stabilizing rod 752, and the spring 754 is located above the inner embedded sheet 751, and the limiting block 753 is located below the limiting block 753 at the same time;

[0080] In some embodiments, more specifically, when the expansion airbag 74 is no longer heated by the second heating tube 64, it will cool and shrink and then return to the initial position. Since the spring 754 loses pressure, the spring 754 can push the inner sheet 751 to move downward so that the moisture absorber frame 72 returns to the equilibrium position. Through the arrangement of the stabilizing rod 752 and the spring 754, the inner sheet 751 can smoothly return to the initial position and at the same time can make the inner sheet 751 smoother in the process of moving upward.

[0081] In some embodiments, more specifically, the first support arm 71 is located in the middle of the desiccant frame 72, and the second support arm 73 is located on the left side of the first support arm 71. In the initial state, the sum of the lengths of the second support arm 73, the upper moving rod 75 and the third support arm 76 is the same as the length of the first support arm 71 to keep the desiccant frame 72 in a balanced position.

[0082] It should also be noted that the moisture-absorbing particles are known materials in the prior art and may be silica gel moisture-absorbing particles or other moisture-absorbing particles. At the same time, the signal transmission and control between the humidity sensor and the first heating tube 63, the second heating tube 64 and the drive motor 32 are also known electrical control principles in the prior art and will not be elaborated in detail in the present invention.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
