[0028] See also Figure 4-5 The drying component 65 in this embodiment includes a receiving frame 651 built into the drying box 64, a guide rod 652 laterally inserted into the upper end of the receiving frame 651 for supporting and fastened to the two sides of the drying box 64, and a through-hole plate 653 rotatably connected to the lower end of the receiving frame 651. In this way, the receiving frame 651 and the through-hole plate 653 can be used to store and place the dry powder, so as to achieve moisture absorption and drying treatment for the cold air with moisture.

[0031] See also Figure 6The filter assembly 67 in this embodiment includes a clamp 671 which is correspondingly and tightly connected to the outer side of the air inlet end of the air cooler 62, a connecting frame 672 installed at the lower end of the clamp 671 for supporting cooperation, a scraper 673 which is correspondingly installed horizontally at the upper end of the middle part of the connecting frame 672, a vertical rod 674 which is vertically inserted into the bottom of the scraper 673, a compression spring 675 which is correspondingly installed on the outer side of the vertical rod 674 to achieve elastic compression cooperation, a combination plate 676 which is tightly connected to the left side of the connecting frame 672, a filter screen 677 which is rotatably sleeved on the outer side of the air inlet end of the air cooler 62 and connected to the middle part of the combination plate 676, and the filter screen 677 is arranged in a cylindrical filter screen shape as a whole, and a bearing is installed in the middle of the right side of the filter screen 677 to connect to the outer side of the air inlet end of the air cooler 62, so as to ensure the smoothness of the subsequent rotation process.

[0032] To further explain, the vertical rod 674 and the compression spring 675 are symmetrically arranged along the left and right lower end of the scraper 673, and the vertical rods 674 on both sides are plugged into the inside of the connecting frame 672 to ensure that the vertical rod 674 and the compression spring 675 can cooperate with each other to make the scraper 673 and the outer side of the filter 677 stably abut each other, thereby ensuring the stability of subsequent scraping and cleaning activities.

[0033] Here’s how it works:

[0034] When the control system is to be used, the electrical connection between the controller body 5 installed on the front side of the mounting plate 4 and the external air source hot air blower can be realized through wiring, and a quick combination docking activity can be realized. After the docking activity is completed, the controller body 5 can be used to realize intelligent control of the operation speed, time and state of the air source hot air blower, so as to make the air source hot air blower run efficiently and energy-saving as a whole, and avoid the air source hot air blower from running too long or too short;

[0035] When the controller body 5 is in the control state, a large amount of heat will be generated. In order to avoid overheating and damage to the controller body 5, heat dissipation holes 3 are provided on the left and right sides of the control box 1 to achieve auxiliary heat dissipation. In order to improve the heat dissipation effect, the air cooler 62 provided inside the fan box 61 can be driven to make the air cooler 62 extract the hot air inside the control box 1 and convert it into cold air. The generated cold air can be transmitted to the left along the duct 63 to enter the drying box 64. In this way, the cold air entering the drying box 64 will be placed inside the receiving frame 651. The drying powder is in contact with each other, thereby realizing the adsorption and drying of the moisture inside the cold air, so that the moisture inside the cold air is reduced. In this way, the cold air that has completed moisture absorption can enter the control box 1 along the exhaust pipe 66 connected to the lower end of the right side of the drying box 64 to realize cooling and heat dissipation coordination, and the cold air that enters the control box 1 for cooling can cooperate with the suction effect of the air cooler 62 again to perform cooling and moisture absorption activities again, so that the cold air circulates into the control box 1 to realize efficient cooling and heat dissipation, thereby achieving the advantages of circulating cooling and cooling, and improving the heat dissipation effect of the controller body 5;

[0036] Later, when the drying powder in the receiving frame 651 needs to be replaced, the receiving frame 651 can be directly pulled as a whole, so that the receiving frame 651 can be moved out in cooperation with the guide rod 652 laterally inserted at the upper end. When the through-hole plate 653 installed at the bottom of the receiving frame 651 is completely moved out of the drying box 64, the rotating shaft 6a4 provided in the connecting structure 6a can be rotated to make the rotating shaft 6a4 realize the overall rotation of the outer connected block 6a5 by 90 degrees. As a result, the block 6a5 can be rotated from the horizontal abutment to the vertical unlocking state, so that the block 6a5 can pass through the slot 6a3 provided at the upper end of the fastening strip 6a2 to After the unlocking activity is completed, the through-hole plate 653 will be opened along the bottom of the receiving frame 651, and cooperate with the supporting effect of the inclined notch on the left side of the drying box 64 to make the through-hole plate 653 stably tilted and opened, so that the old drying powder carried by the upper end of the through-hole plate 653 can be easily taken out. Subsequently, the through-hole plate 653 is completely closed through the cooperation of the connecting structure 6a to seal the lower end of the receiving frame 651, so as to form a new drying powder carrying space, so that the new drying powder can be added to the inside of the receiving frame 651 to be used for moisture absorption and drying again, thereby realizing the convenient replacement of drying powder and enhancing the convenience of operation;

[0037] Secondly, in order to avoid the inhalation of dust when the air cooler 62 is in the suction activity, a filter assembly 67 is provided at the air inlet end of the air cooler 62, that is, during the suction activity, the filter 677 installed inside the filter assembly 67 can achieve auxiliary filtering and purification to reduce the entry of dust. Later, when the outside of the filter 677 is to be cleaned, the filter 677 can be directly rotated as a whole, so that the filter 677 is supported by the combination plate 676 to move along the air inlet end of the air cooler 62. The scraper 673 is tightened on the middle upper end of the connecting frame 672 through the auxiliary support of the vertical rods 674 and the compression spring 675 on both sides, so that the outer side of the filter screen 677 can be scraped accordingly, thereby quickly cleaning the dust. If it is necessary to disassemble the filter assembly 67 as a whole, it is only necessary to release the fast connection between the clamp 671 and the air inlet end of the cooler 62 to remove the filter assembly 67 as a whole, thereby achieving the advantages of suction-assisted filtration and convenient scraping and cleaning.

[0038] The utility model provides an energy-saving control system for an air source hot air blower, which is provided with a circulating heat dissipation device 6, that is, through the cooperation of the cold air blower 62, the duct 63, the drying box 64 and the drying component 65, air cooling and moisture absorption can be achieved, so that the cold air can stably enter the inside of the control box 1 to achieve cooling and heat dissipation coordination, so that the controller body 5 can achieve efficient heat dissipation, and the connecting structure 6a provided on the left side of the through-hole plate 653 can make the through-hole plate 653 convenient to open and close, so that the placed dry powder can be conveniently replaced, thereby achieving the advantages of circulating cooling and improving the heat dissipation effect of the controller body 5, and a filter component 67 is provided, that is, the filter screen 677 can filter the air drawn in, and by manually rotating the filter screen 677, the filter screen 677 can be brought into contact with the scraper 673 abutting against the bottom, so that the dust can be quickly scraped and cleaned, and the vertical rod 674 and the compression spring 675 are cooperated to strengthen the abutment firmness, thereby achieving the advantages of suction-assisted filtering coordination and convenient scraping and cleaning.
