[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a baking device with uniform heating, which has the following beneficial effects:

[0019] 1. The baking device with uniform heating is started by controlling the first motor and the hot air blower. The operation of the first motor drives the rotating column to rotate, and the rotation of the rotating column drives the three receiving trays to rotate accordingly, and the hot air blower blows out hot air. Since the hot air box is sealed as a whole, the hot air can only be transmitted to the baking box through the hot air pipe, and each hot air pipe is just above the corresponding receiving tray, so the hot air can be transmitted to the receiving tray one by one to dry the tea leaves in the receiving tray.

When the second motor is started, the reciprocating screw can drive the movable block with a limiting structure to reciprocate up and down. When the movable block moves downward, the pressure plate is driven to move downward. The downward movement of the pressure plate causes the right end of the hinged plate to tilt downward. Then, the other end of the hinged plate will rise, so that the knocking block at the bottom of the serving tray can knock the bottom of the serving tray, which has the effect of shaking the tea leaves inside the serving tray after knocking. When the serving tray rotates, even if a part of the tea leaves are unevenly distributed due to vibration, they will be smoothed out under the obstruction of the L-shaped smoothing plate, thereby playing an effect of assisting uniform drying.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] like Figure 1-3 As shown, the utility model provides a baking device with uniform heating, including a baking box 1, a hot air box 2 is fixedly installed on the baking box 1, a drying mechanism 4 is installed in the baking box 1, and the drying mechanism 4 includes: a first chassis 401;

[0029] The first chassis 401 is fixedly mounted on the outer wall of the top of the baking box 1, and a first motor is fixedly mounted inside the first chassis 401. The output end of the first motor is fixedly connected to a rotating column 402 via a coupling, and the bottom of the rotating column 402 is rotatably connected to the inner wall of the bottom of the baking box 1 via a bearing.

[0030] A holding plate 3 is fixedly sleeved on the outer wall of the rotating column 402, and a hot air pipe 403 is connected and fixedly connected to the hot air box 2, one end of the hot air pipe 403 extends into the hot air box 2, and the other end extends into the inside of the baking box 1. By providing the hot air pipe 403, the two relatively sealed boxes of the baking box 1 and the hot air box 2 are connected.

[0031] A hot air blower is fixedly installed inside the hot air box 2. There are three receiving trays 3 and three hot air pipes 403, which are arranged in an array. Each hot air pipe 403 is higher than a corresponding receiving tray 3. The hot air blower blows out hot air. Since the hot air box 2 is sealed as a whole, the hot air can only be conducted to the baking box 1 through the hot air pipe 403. Each hot air pipe 403 is just above the corresponding receiving tray 3, and the hot air can be conducted to the receiving tray 3 one by one to dry the tea leaves in the receiving tray 3.

[0032] The front and rear of the baking box 1 are both opened, and tempered glass is installed at the openings on both sides. By arranging the tempered glass, it is actually a glass door, which is easy to open and easy to observe the internal situation through the glass.

[0033] In this embodiment, by controlling the first motor and the hot air blower to start, the operation of the first motor drives the rotating column 402 to rotate, and the rotation of the rotating column 402 drives the three serving trays 3 to rotate accordingly, and the hot air blower blows out hot air. Since the movable door on the back of the hot air box 2 is also closed, the movable door exists to facilitate the maintenance of the hot air blower. Therefore, the entire hot air box 2 is sealed, and the hot air can only be transmitted to the baking box 1 through the hot air pipe 403. Each hot air pipe 403 is just above the corresponding serving tray 3, and can transmit the hot air to the serving tray 3 one by one to dry the tea leaves in the serving tray 3.

[0034] Example 2

[0035] like Figure 1-3As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, an auxiliary mechanism 5 is provided on the baking box 1, and the auxiliary mechanism 5 includes: a second chassis 501, the second chassis 501 is fixedly installed on one side outer wall of the baking box 1, a second motor is fixedly installed inside the second chassis 501, the output end of the second motor is fixedly connected to a reciprocating screw rod 502 through a coupling, a movable block 503 is threadedly connected to the outer wall of the reciprocating screw rod 502, the movable block 503 is slidably connected to one side outer wall of the baking box 1, a square surface of the movable block 503 forms a limiting structure under contact with the outer wall of the baking box 1, and the reciprocating screw rod 502 can drive the movable block 503 with the limiting structure to reciprocate up and down when the second motor is started.

[0036] A through hole is provided on the baking box 1, and a hinge column is fixedly installed at the through hole. A hinge plate 505 is movably sleeved on the outer wall of the hinge column, and a semicircular knocking block 506 is fixedly installed on the hinge plate 505. A pressing plate 504 is in contact with the hinge plate 505, and the pressing plate 504 is fixedly connected to the movable block 503. When the movable block 503 moves downward, the pressing plate 504 is driven to move downward, and the downward movement of the pressing plate 504 causes the right end of the hinge plate 505 to tilt downward, then the other end of the hinge plate 505 will rise, so that the knocking block 506 at the bottom of the serving tray 3 can knock the bottom of the serving tray 3, so that the tea leaves inside the serving tray 3 will shake after being knocked.

[0037] A fixing ring 404 is rotatably sleeved on the outer wall of the rotating column 402, and an L-shaped smoothing plate 405 is fixedly installed on the fixing ring 404. After being struck by the striking block 506, the distribution of the tea leaves in the receiving tray 3 will no longer be uniform. Therefore, by setting the smoothing plate 405 at a certain height, when the receiving tray 3 rotates, even if some of the tea leaves are unevenly distributed due to vibration, they will be smoothed out under the obstruction of the L-shaped smoothing plate 405, thereby achieving the effect of assisting uniform drying.

[0038] In this embodiment, by controlling the start-up of the second motor, the reciprocating screw rod 502 can drive the movable block 503 with a limiting structure to reciprocate up and down under the start-up of the second motor. When the movable block 503 moves downward, the pressure plate 504 is driven to move downward. The downward movement of the pressure plate 504 causes the right end of the hinged plate 505 to tilt downward, and then the other end of the hinged plate 505 will rise, so that the knocking block 506 at the bottom of the serving tray 3 can knock the bottom of the serving tray 3, which has the effect of shaking the tea leaves inside the serving tray 3 after knocking. When the serving tray 3 rotates, even if a part of the tea leaves are unevenly distributed due to vibration, they will be smoothed out under the obstruction of the L-shaped smoothing plate 405, thereby playing an effect of assisting uniform drying.

[0039] The working principle of this uniformly heated baking device will be described in detail below.

[0040] like Figure 1-3 As shown, when in use, by controlling the first motor and the hot air blower to start, the operation of the first motor drives the rotating column 402 to rotate, and the rotation of the rotating column 402 drives the three serving trays 3 to rotate accordingly, and the hot air blower blows out hot air. Since the movable door on the back of the hot air box 2 is also closed, the movable door exists to facilitate the maintenance of the hot air blower. Therefore, the entire hot air box 2 is sealed, and the hot air can only be transmitted to the baking box 1 through the hot air pipe 403, and each hot air pipe 403 is just above the corresponding serving tray 3, and can transmit the hot air to the serving tray 3 one by one, so as to dry the tea leaves in the serving tray 3. By controlling the second motor to start, the reciprocating screw rod 502 When the second motor is started, the movable block 503 with a limiting structure can be driven to reciprocate up and down. When the movable block 503 moves downward, the pressing plate 504 is driven to move downward. The downward movement of the pressing plate 504 causes the right end of the hinged plate 505 to tilt downward, and then the other end of the hinged plate 505 will rise, so that the knocking block 506 at the bottom of the serving tray 3 can knock the bottom of the serving tray 3, which has the effect of shaking the tea leaves inside the serving tray 3 after knocking. When the serving tray 3 rotates, even if a part of the tea leaves are unevenly distributed due to vibration, they will be smoothed out under the obstruction of the L-shaped smoothing plate 405, thereby assisting in uniform drying.
