[0038] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0039] like Figures 1 to 12 As shown, the embodiment of the present invention provides an intelligent white tea withering device, including a mounting platform 101, a photovoltaic panel device 102, a water storage bag 103, a heat preservation tank 104 and a withering cabinet 105 are arranged on the surface of the mounting platform 101, including:

[0040] A concave mirror 201 is installed on the surface of the heat preservation tank 104, and a heat collecting tube 203 is arranged on one side of the concave mirror 201. The concave mirror 201 focuses solar energy on the surface of the heat collecting tube 203, so that the water inside the heat collecting tube 203 reaches the set temperature and then enters the interior of the heat preservation tank 104;

[0041] The insulation tank 104 is slidably connected to an insulation plate 219, which is used to monitor the amount of water entering the insulation tank 104 and to prevent the heat carried by the water below the insulation plate 219 from escaping to the top of the insulation plate 219.

[0042] A plurality of tea trays 306 are arranged in parallel from top to bottom inside the withering cabinet 105, and a withering light box 305 is arranged above each of the tea trays 306, through which the tea leaves on the tea trays 306 are illuminated by light;

[0043] The interior of the withering cabinet 105 is symmetrically installed with scissor-type telescopic frames 302 , and the tea trays 306 are equidistantly arranged on the corresponding central pins of the two scissor-type telescopic frames 302 to adjust the position of the tea trays 306 inside the withering cabinet 105 .

[0044] In the embodiment of the present invention, the rectangular frame of the tea tray 306 is evenly provided with through slots to facilitate the circulation of air. The rectangular frame is a layer of mesh made of transparent glass fibers. The withering cabinet 105 is made of transparent glass to facilitate the exposure to sunlight. When withering white tea, the processed white tea is spread on the glass fiber mesh in the tea tray 306. When the sun is sufficient during the day, the scissor-type telescopic frame 302 is extended, and the extension of the scissor-type telescopic frame 302 increases the distance between the tea trays 306, so that the tea leaves carried in the tea trays 306 are exposed to sunlight. At night or when the sun is insufficient, the scissor-type telescopic frame 302 can be contracted to reduce the distance between the scissor-type telescopic frames 302. The adjacent tea trays 306 are exposed to light through the withering light box 305, so that the withering efficiency of the tea leaves is improved, while promoting chemical changes in the tea leaves, thereby increasing the unique aroma of the white tea.

[0045] At the same time, the hotter water in the heat preservation tank 104 located below the insulation plate 219 maintains the temperature inside the withering cabinet 105 at a set value through heat transfer, thereby improving the withering efficiency of the tea leaves;

[0046] A breathing valve 220 may be installed on the surface of the insulation tank 104 to balance the air pressure inside the insulation tank 104 and maintain the safety and stability of the device.

[0047] A first bracket 202 is fixedly connected to the surface of the insulation tank 104, a heat collecting tube 203 is fixedly connected to the surface of the first bracket 202, a fixing ring sheet 204 is symmetrically fixedly connected to the inside of the heat collecting tube 203, sealing ring sheets 205 are symmetrically arranged between the fixing ring sheets 204, the sealing ring sheets 205 are fixedly connected to the heat collecting tube 203, a first plug body 206 is arranged on the left side of one of the sealing ring sheets 205, and a second plug body 207 is arranged on the left side of the other sealing ring sheet 205, one end of the heat collecting tube 203 is connected to the inside of the water storage bag 103 through a pipeline (not shown in the figure), and the other end of the heat collecting tube 203 is connected to the inside of the insulation tank 104 through a pipeline (not shown in the figure).

[0048] In the embodiment of the present invention, when collecting heat, the concave mirror 201 is used to focus sunlight on a local area of ​​the heat collecting tube 203, so that the inside of the heat collecting tube 203 is quickly heated up. When the water temperature in the heat collecting tube 203 reaches the set value, the second plug 207 is no longer blocked by the corresponding sealing ring 205, so that the water reaching the set temperature value flows to the inside of the heat preservation tank 104, and then the second plug 207 is reset, and the first plug 206 is no longer blocked by the corresponding sealing ring 205, so that the water with a lower temperature in the water storage bag 103 flows to the inside of the heat collecting tube 203. The height of the insulation board 219 inside the heat preservation tank 104 can reflect the solar radiation conditions of the day.

[0049] Specifically, a sensor can be installed on the surface of the insulation board 219. The installation and use of the sensor are well known in the prior art and will not be described in detail here. The sensor senses the relative position of the insulation board 219 and the insulation tank 104, so that the heat value carried by the liquid inside the insulation tank 104 can be calculated, and then the internal temperature of the withering cabinet 105 can be adjusted at night to keep the tea leaves inside the withering cabinet 105 at a better withering rate.

[0050] A first connecting piece 208 is fixedly connected to the surface of the first plug body 206, a second spring 222 is fixedly connected to the surface of the first connecting piece 208, an end of the second spring 222 away from the first connecting piece 208 is fixedly connected to the corresponding fixed ring piece 204, a second plug body 207 is fixedly connected to the surface of the second connecting piece 211, a first spring 221 is fixedly connected to the surface of the second connecting piece 211, an end of the first spring 221 away from the second connecting piece 211 is fixedly connected to the corresponding fixed ring piece 204.

[0051] The surface of the second connecting piece 211 is symmetrically fixedly connected with a U-shaped rod 212, the surface of the U-shaped rod 212 is symmetrically provided with a first fixing plate 214, the surface of each first fixing plate 214 is fixedly connected with a second fixing plate 216, a limiting roller 215 is provided between two adjacent first fixing plates 214, the limiting roller 215 is rotatably connected to the corresponding two first fixing plates 214 through two first bearings, a pull rod 217 is provided between the adjacent second fixing plates 216, and the pull rod 217 is connected to the corresponding two second fixing plates 2 16 is fixedly connected, a first circular hole provided on the surface of the first fixing plate 214 is rotatably connected to the U-shaped rod 212, a first torsion spring 213 is provided on the surface of the U-shaped rod 212, two ends of the first torsion spring 213 are respectively fixedly connected to the second connecting piece 211 and the corresponding first fixing plate 214, a rope body 218 is rotatably connected to the surface of the pull rod 217 through a second bearing, a first connecting rod 209 is fixedly connected to the surface of the first plug body 206, and one end of the rope body 218 away from the pull rod 217 is fixedly connected to the first connecting rod 209.

[0052] In the embodiment of the present invention, one end of the heat collecting pipe 203 close to the first plug body 206 is connected to the inside of the heat preservation tank 104 through a pipe (not shown in the figure), and the other end is connected to the inside of the water storage bag 103 through a pipe (not shown in the figure). When the water temperature inside the heat collecting pipe 203 reaches the set value, the continuously increasing water temperature causes the air pressure between the two sealing ring pieces 205 inside the heat collecting pipe 203 to continuously increase, so that the first plug body 206 drives the first connecting piece 208 to move in the direction of compressing the second spring 222. At this time, the first plug body 206 no longer blocks the sealing ring piece 205 adjacent to it. The liquid inside the heat collecting pipe 203 that reaches the set value flows from the gap between the sealing ring piece 205 and the first plug body 206 and the pores on the surface of the first connecting piece 208 to the pipe (not shown in the figure) connected to the heat preservation tank 104, and enters the inside of the heat preservation tank 104. As the pressure between the two sealing ring pieces 205 decreases, the first plug body 206 is reset under the action of the elastic potential energy of the first spring 221.

[0053] Under the action of negative pressure, the second plug body 207 moves in the direction of stretching the first spring 221. During this process, the water inside the water storage bag 103 passes through the gap between the second plug body 207 and the corresponding sealing ring sheet 205 through a pipeline (not shown in the figure) and enters between the two sealing ring sheets 205, and heats up under the action of the concave mirror 201.

[0054] A first connecting plate 301 is provided inside the withering cabinet 105, and a scissor-type telescopic frame 302 is symmetrically installed on the surface of the first connecting plate 301. An electric-controlled telescopic cylinder 303 is fixedly connected to the surface of the mounting platform 101, and the telescopic end of the electric-controlled telescopic cylinder 303 is fixedly connected to one of the center pins of the scissor-type telescopic frame 302. The tea tray 306 is fixedly connected to the corresponding center pin. The bottom surface of the first connecting plate 301 is fixedly connected to a top plate 304, and the top plate 304 is fixedly connected to the corresponding center pin. The top plate 304 is hinged to the adjacent withering light box 305 below, and the remaining withering light boxes 305 are all hinged to the adjacent tea tray 306 above.

[0055] In the embodiment of the present invention, when the first plug body 206 moves in the direction of compressing the second spring 222, the two rope bodies 218 on the first connecting rod 209 pull the pull rod 217, so that the limiting roller 215 on the first fixing plate 214 moves around the U-shaped rod 212 in the direction of overcoming the elastic potential energy of the first torsion spring 213 until the limiting roller 215 contacts the second plug body 207. At this time, the second plug body 207 is constrained by the first spring 221 and the limiting roller 215. It has a stronger resistance to the negative pressure inside the heat collecting tube 203, so that as much water as possible whose temperature reaches the set value can pass into the interior of the insulation tank 104. When the negative pressure inside the heat collecting tube 203 is large enough, as the first plug body 206 is reset, the limiting roller 215 is reset under the action of the elastic potential energy of the first torsion spring 213 until it no longer hinders the movement of the second plug body 207. At this time, the second plug body 207 moves in the direction of stretching the first spring 221, so as to inject low-temperature water into the interior of the heat collecting tube 203 for heating.

[0056] The surface of the tea tray 306 is symmetrically provided with first slide grooves 307 , and the interiors of the first slide grooves 307 are slidably connected with first sliders 308 , and the first sliders 308 are hinged to the withering light box 305 adjacent above.

[0057] An isolation plate 309 is fixedly connected to the upper surface of the first connecting plate 301, and the isolation plate 309 is slidably connected to the withering cabinet 105. A circulating air box 310 is symmetrically arranged on the surface of the isolation plate 309. The circulating air box 310 is fixedly connected in a rectangular groove opened on the surface of the isolation plate 309. A plurality of first ventilation holes are evenly opened on the bottom surface of the circulating air box 310. A plurality of second ventilation holes are opened at positions below the isolation plate 309 on the opposite surfaces of the two circulating air boxes 310. An air pump 312 and a drying box 311 are installed above the isolation plate 309 at a position between the two circulating air boxes 310. The air inlet of the drying box 311 is connected to the interior of one of the circulating air boxes 310 through a pipeline, the air outlet of the drying box 311 is connected to the interior of the air inlet of the air pump 312 through a pipeline, and the air outlet of the air pump 312 is connected to the interior of the other circulating air box 310 through a pipeline.

[0058] A first connecting pipe 314 is arranged above the installation platform 101, and both ends of the first connecting pipe 314 are respectively fixedly connected to the reserved holes opened on the surfaces of the water storage bag 103 and the heat preservation tank 104, and a second connecting pipe 315 is fixedly connected to the first through groove opened on the surface of the first connecting pipe 314, and an automatic mixing valve 316 is installed on the surface of the second connecting pipe 315. A water pump 317 is arranged on one side of the automatic mixing valve 316, and the liquid outlet of the water pump 317 is connected to the inside of the liquid inlet of the water pump 317 through a pipeline. An insulation layer body 318 is fixedly connected to the surface of the withering cabinet 105, and a coil 313 is arranged inside the insulation layer body 318, and one end of the coil 313 is connected to the liquid outlet of the water pump 317, and the other end of the water pump 317 is connected to the inside of the water storage bag 103 through a pipeline (not shown in the figure).

[0059] In the embodiment of the present invention, when the temperature is low at night, in order to maintain the withering efficiency of tea leaves at a better level, the electric control telescopic cylinder 303 is contracted, thereby driving the scissor-type telescopic frame 302 to contract. The contraction of the scissor-type telescopic frame 302 causes the withering light box 305 to drive the first slider 308 to slide inside the first slide groove 307 until the upper surface and the bottom surface of the first slide groove 307 are both in contact with the withering light box 305. During this process, the isolation plate 309 slides downward inside the withering cabinet 105 until the tea tray 306 is in the area surrounded by the isolation plate 309 and the heat-insulating layer 318. The tea leaves in the tea tray 306 are illuminated by the withering light box 305 to promote chemical changes in the tea leaves.

[0060] Start the water pump 317, and through the cooperation of the automatic mixing valve 316, mix the water in the heat preservation tank 104 and the water storage bag 103 to the set temperature, and then input it into the coil 313 through the water pump 317, so that the temperature of the area surrounded by the isolation plate 309 and the heat preservation layer 318 is maintained at the set value, and the water input into the coil 313 eventually flows back into the water storage bag 103;

[0061] In order to maintain the withering humidity environment of tea leaves, a humidity sensor is installed on the surface of the tea tray 306 to monitor the humidity change of tea leaves withering. The use and installation of the humidity sensor are well known in the prior art and will not be described in detail here. When the humidity is higher than the set value, the air pump 312 is started to make the air flow under the isolation plate 309 flow from one of the circulating air boxes 310 to the drying box 311. After being dried in the drying box 311, the air flow returns to the bottom of the isolation plate 309 through the air pump 312 and the other circulating air box 310. This process reduces the mixing of external air, maintains a clean environment for tea leaves withering, and also reduces the participation of external low-temperature gas in the heat exchange of the gas under the isolation plate 309.

[0062] In order to monitor the withering progress of the tea leaves, a gravity sensor can be installed on the surface of the drying box 311. The installation and use of the gravity sensor are well known in the prior art and will not be described in detail here. The water loss and water loss efficiency of the tea leaves inside the device can be known through the weight change of the drying box 311, so that the corresponding temperature adjustment can be performed to keep the tea leaves at a better withering efficiency and reduce the loss caused by excessive withering.

[0063] An L-shaped rod 401 is fixedly connected to the surface of the withering cabinet 105, and an L-shaped plate 403 is rotatably connected to the surface of the L-shaped rod 401 via a third bearing. A second torsion spring 402 is provided on the surface of the L-shaped rod 401, and two ends of the second torsion spring 402 are respectively fixedly connected to the withering cabinet 105 and the L-shaped plate 403. A spring rope 404 is provided on the surface of the withering cabinet 105, and two ends of the spring rope 404 are respectively fixedly connected to the cabinet body of the withering cabinet 105 and the door body of the withering cabinet 105.

[0064] In the embodiment of the present invention, when the power of the device is lower than the set value, the scissor-type telescopic frame 302 is extended until the isolation plate 309 pushes the L-shaped piece 403 away from the surface of the door of the withering cabinet 105, and the door of the withering cabinet 105 is opened under the action of the spring rope 404, so that the tea tray 306 is exposed to the outside, thereby preventing the tea from deteriorating due to high humidity inside the device due to insufficient power;

[0065] When it is necessary to take or put tea leaves, the door of the withering cabinet 105 can also be opened in the above manner.
