[0033] The embodiment of this application provides a device for drying Chinese herbal medicines by sunning. Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 as shown. Figure 1 is a schematic diagram of the overall structure of a device for drying Chinese herbal medicines provided by the embodiment of this application. Figure 1 , Figure 2 is Figure 1 an exploded view of the structure of the device for drying Chinese herbal medicines in Figure 3 is a schematic diagram of the drying net 50 being received in the box body 10 after the telescopic component 40 is shortened. Figure 4 is a schematic diagram of the drying net 50 moving outside the box body 10 after the telescopic component 40 is extended.
[0034] The device for drying Chinese herbal medicines includes a box body 10, a box cover 20, a heating device 30, a telescopic component 40, and a plurality of drying nets 50.
[0035] Among them, an opening 10a is provided at the top of the box body 10, and the box cover 20 is arranged at the opening 10a for opening or closing the box body 10. The heating device 30 is fixed on the inner wall of the box body 10. Both the telescopic component 40 and the plurality of drying nets 50 are arranged in the box body 10. The plurality of drying nets 50 are stacked and arranged at intervals, and are all connected to the telescopic component 40. The telescopic component 40 can extend out of the box body 10 from the opening 10a and drive the plurality of drying nets 50 outside the box body 10.
[0036] In this application, a drying device and a telescopic assembly 40 that can extend out of the box body 10 are arranged in the box body 10, and a plurality of drying nets 50 are provided. When the external environment is suitable for natural drying (such as a dry sunny day), the box cover 20 can be opened to extend the telescopic assembly 40, so as to drive the plurality of drying nets 50 outside the box body 10, and then naturally dry the Chinese herbal medicines on the drying nets 50. When the external environment is not suitable for natural drying (such as rainy weather), the telescopic assembly 40 can be shortened to retract the drying nets 50 into the box body 10, then close the box cover 20, and turn on the heating device 30 to dry the Chinese herbal medicines on the drying nets 50. That is to say, the Chinese herbal medicine drying and airing device provided by this application can switch the corresponding working state according to the external environment, thereby effectively improving the drying efficiency of Chinese herbal medicines.
[0037] It can be understood that the above heating device 30 can be an electric heating tube, an electric heating wire, etc. One heating device 30 can be provided, or multiple heating devices 30 can be provided. This application does not make special limitations on this.
[0038] The box cover 20 can be directly buckled on the box body 10, and the box cover 20 and the box body 10 can also be connected in a sliding manner, a rotating manner, etc. For example, please refer to Figure 5 as shown Figure 5 which is a schematic diagram of the overall structure of a Chinese herbal medicine drying and airing device provided by an embodiment of this application Figure 2 , the box cover 20 and the box body 10 can be rotatably connected through a hinge mechanism 70. In this way, when in use, the box body 10 can be opened or closed by rotating the box cover 20, which is more convenient for operation.
[0039] The above drying nets 50 and telescopic assembly 40 can be made of metal, such as aluminum alloy, stainless steel, etc.
[0040] In order to facilitate the staff to observe the state of the Chinese herbal medicines in the box body 10 at any time and avoid the situation that the Chinese herbal medicines are scorched, please continue to refer to Figures 1 to 4 as shown, a transparent observation window 10c is also provided on the box body 10. For example, the observation window 10c can be made of high-temperature resistant tempered glass.
[0041] In some embodiments, universal wheels 80 are further provided at the bottom of the box body 10, so as to facilitate the movement and handling of the Chinese herbal medicine drying and airing device. For example, on a dry sunny day, the Chinese herbal medicine drying and airing device is pushed outdoors to naturally dry the Chinese herbal medicines. On rainy days, the Chinese herbal medicine drying and airing device can be pushed indoors, and the heating device 30 is used to heat and dry the Chinese herbal medicines.
[0042] In some embodiments, please continue to refer to Figure 2 and Figure 4As shown, the telescopic assembly 40 may include a plurality of telescopic rods 41, and the plurality of drying nets 50 include a first drying net 50a closest to the bottom of the box body 10. Among them, two adjacent drying nets 50 are connected by a telescopic rod 41, and the first drying net 50a is connected to the bottom of the box body 10 by a telescopic rod 41.
[0043] In this way, by extending the telescopic rod 41, not only can the plurality of drying nets 50 be driven outside the box body 10 to naturally dry the Chinese herbal medicines, but also the distance between two adjacent drying nets 50 can be adjusted by the telescopic rod 41. That is, when the drying net 50 is moved out of the box body 10 for natural drying, the extension of the telescopic rod 41 increases the distance between two adjacent drying nets 50, which is more conducive to the illumination and ventilation of the Chinese herbal medicines on each drying net 50.
[0044] Furthermore, a plurality of telescopic rods 41 are provided between two adjacent drying nets 50, and the plurality of telescopic rods 41 are arranged at equal intervals along the circumferential direction of the drying net 50. A plurality of telescopic rods 41 are provided between the first drying net 50a and the bottom of the box body 10, and the plurality of telescopic rods 41 are arranged at equal intervals along the circumferential direction of the first drying net 50a.
[0045] In this way, the plurality of telescopic rods 41 arranged at equal intervals can provide more stable support for the drying net 50, and during the telescopic process of the telescopic rod 41, each telescopic rod 41 and each drying net 50 can also be evenly stressed, avoiding deflection or inclination of the drying net 50.
[0046] Specifically, please refer to Figure 6 as shown Figure 6 is a schematic structural diagram of the telescopic rod 41. The telescopic rod 41 may include a sleeve 412, a rod body 411, and an elastic button 413. Among them, the sleeve 412 is sleeved outside the rod body 411, and a plurality of limiting through holes 412a are provided on the tube wall of the sleeve 412, and the plurality of limiting through holes 412a are arranged at intervals along the axis of the sleeve 412. The elastic button 413 is provided on the outer wall of the rod body 411, and the elastic button 413 can extend into the limiting through hole 412a.
[0047] During installation, the end of the sleeve 412 away from the rod body 411 and the end of the rod body 411 away from the sleeve 412 can be fixedly connected to two adjacent drying nets 50 respectively. When in use, the length of the telescopic rod 41 can be adjusted by controlling the elastic button 413 to extend into different limiting through holes 412a. For example, press the elastic button 413 inward with one hand to make it withdraw from the limiting through hole 412a, and hold the rod body 411 with the other hand and push or pull it inward or outward along the axis of the sleeve 412. When the rod body 411 moves, the elastic button 413 will pop out every time it passes through a limiting through hole 412a, and at this time, it needs to be pressed again until the rod body 411 is adjusted to the required position. That is to say, by adjusting the elastic button 413 to pop out from different limiting through holes 412a, the adjustment of the length of the telescopic rod 41 can be achieved.
[0048] On the above basis, please refer to Figure 7 as shown in Figure 7 which is a schematic structural diagram of the box cover 20. The Chinese herbal medicine drying and airing device may further include an exhaust duct 21, a flap 23 and a rotating shaft 22. Among them, an exhaust port 20a is provided on the box cover 20, and the exhaust duct 21 is arranged at the exhaust port 20a; an installation through hole is opened on the pipe wall of the exhaust duct 21, and the rotating shaft 22 is passed through the installation through hole; the flap 23 is located in the exhaust duct 21 and is fixedly connected to the rotating shaft 22, and the flap 23 is used to open or close the exhaust port 20a.
[0049] In this way, when drying the Chinese herbal medicine in the box body 10, the flap 23 can be rotated to open the exhaust port 20a, so that the water vapor generated by the evaporation of the moisture in the Chinese herbal medicine in the box body 10 can be discharged to the outside of the box body 10 in time, which is beneficial to improving the drying efficiency.
[0050] Furthermore, please go back and refer to Figure 2 and Figure 3 and in combination with Figure 8 and Figure 9 as shown in Figure 8 which is a schematic structural diagram of the box body 10, Figure 9 and
[0051] which is a schematic diagram of the relative position of the one-way air inlet valve 11 and the box body 10. The Chinese herbal medicine drying and airing device may further include an exhaust fan 24, a one-way air inlet valve 11 and a control module 60. Among them, the control module 60 is arranged on the outer wall of the box body 10, a bracket 25 is provided at the end of the exhaust duct 21 away from the box cover 20, the exhaust fan 24 is fixed on the bracket 25 and is electrically connected to the control module 60. An air inlet 10b is provided at the bottom of the box body 10, and the one-way air inlet valve 11 is arranged at the air inlet 10b. Among them, the one-way air inlet valve 11 may include a valve cover 111 and a hinge support 112 arranged in the box body 10. The valve cover 111 is rotatably connected to the bottom of the box body 10 through the hinge support 112, and the cross-sectional area of the valve cover 111 is larger than the cross-sectional area of the air inlet 10b.
[0052] In this way, when the air outlet 20a is opened, the exhaust fan 24 can be turned on simultaneously to accelerate the discharge speed of the water vapor in the box body 10. After the exhaust fan 24 is turned on, a negative pressure will be formed in the box body 10, and the air pressure difference inside and outside the box body 10 will push the one-way intake valve 11 at the air inlet 10b at the bottom of the box body 10 to open, that is, the valve cover 111 rotates towards the direction close to the drying net 50 to the position of the dotted line in the figure... The relatively dry air in the external environment can enter the box body 10 from the air inlet 10b in time for supplementation. After the exhaust fan 24 is turned off, the air pressure difference inside and outside the box body 10 disappears, and the valve cover 111 will return to its original position under the action of its own gravity to close the air inlet 10b.
[0053] Furthermore, the above-mentioned Chinese herbal medicine drying and airing device may further include a driving motor 26, which is arranged on the outer wall of the box cover 20 and is electrically connected to the control module 60. The driving motor 26 is connected to the rotating shaft 22, and the driving motor 26 is used to drive the flap 23 to rotate.
[0054] In this way, when drying Chinese herbal medicine, the state of the flap 23 in the exhaust duct 21 can be controlled through the control module 60. For example, a humidity threshold and a time threshold are set. During the drying process, as the moisture in the Chinese herbal medicine evaporates, the humidity in the box body 10 gradually rises. When the humidity in the box body 10 reaches the humidity threshold, the control module 60 controls the driving motor 26 to start, so that the driving motor 26 starts to drive the flap 23 to rotate to the first specified position to open the air outlet 20a. At the same time, the exhaust fan 24 is controlled to turn on, so as to extract the high-humidity air in the box body 10 from the air outlet 20a. After the exhaust fan 24 is turned on, a negative pressure will be formed in the box body 10, and the air pressure difference inside and outside the box body 10 will push the one-way intake valve 11 at the air inlet 10b at the bottom of the box body 10 to open, and the relatively dry air in the external environment can enter the box body 10 from the air inlet 10b for supplementation. When the running time of the exhaust fan 24 reaches the time threshold, the control module 60 controls the exhaust fan 24 to stop, and makes the driving motor 26 start to drive the flap 23 to rotate to the second specified position to close the air outlet 20a.
[0055] Please continue to refer to Figure 8 As shown, a temperature sensor 12 and a humidity sensor 13 are also fixed on the inner wall of the box body 10, and both the temperature sensor 12 and the humidity sensor 13 are electrically connected to the control module 60.
[0056] In this way, when drying Chinese herbal medicines, a display screen can be set on the control module 60. The real-time temperature inside the box body 10 collected by the temperature sensor 12 and the real-time humidity inside the box body 10 collected by the humidity sensor 13 can be displayed on the display screen of the control module 60, facilitating the staff to understand the environmental state inside the box body 10. In addition, the control module 60 can also automatically control the states of the exhaust fan 24 and the flap 23 in the exhaust duct 21 according to the temperature and humidity inside the box body 10. For example, a humidity threshold and a time threshold are set. During the drying process, as the moisture in the Chinese herbal medicines evaporates, the humidity inside the box body 10 gradually rises. When the humidity inside the box body 10 reaches the humidity threshold, the control module 60 controls the driving motor 26 to start, so that the driving motor 26 starts to drive the flap 23 to rotate to the first specified position to open the air outlet 20a. At the same time, the control module 60 controls the exhaust fan 24 to start, so as to extract the high-humidity air inside the box body 10 from the air outlet 20a. After the exhaust fan 24 starts, a negative pressure will be formed inside the box body 10, and the air pressure difference inside and outside the box body 10 will push the one-way intake valve 11 at the air inlet 10b at the bottom of the box body 10 to open, and the dry air in the external environment can enter the box body 10 from the air inlet 10b for supplement. When the running time of the exhaust fan 24 reaches the time threshold, the control module 60 controls the exhaust fan 24 to stop and makes the driving motor 26 start to drive the flap 23 to rotate to the second specified position to close the air outlet 20a.
[0057] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
[0058] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto.
