[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a circulation oven, including a box body 1, a motor 2 is fixedly connected to the upper surface of the box body 1, a reciprocating screw rod 3 is fixedly connected to the output end of the motor 2, a hollow plate 4 symmetrical in upper and lower directions is fixedly connected to the inner wall of the box body 1, a heating wire 5 is fixedly connected to one side of the outer wall of the two hollow plates 4, the reciprocating screw rod 3 is rotatably connected to the inside of the hollow plate 4, and a fan blade 6 symmetrical in upper and lower directions is fixedly connected to the outer wall of the reciprocating screw rod 3. A limiting groove 10 is provided inside the box body 1, a threaded sleeve 7 is threadedly connected to the outer wall of the reciprocating screw rod 3, a placing component is arranged on the outer wall of the threaded sleeve 7, and a heating wire 11 is fixedly connected to one side of the inner wall of the box body 1; the placing component includes a placing basket 8 and a limiting block 9, the placing basket 8 is fixedly connected to the outer wall of the threaded sleeve 7, the outer wall of the placing basket 8 is fixedly connected to the limiting block 9, and the limiting block 9 is slidably connected to the inner wall of the limiting groove 10;

[0032] Specifically, first, the medicine is properly placed inside the placement basket 8. Next, by starting the motor 2, the motor 2 drives the reciprocating screw 3 to rotate inside the box 1. This step is to facilitate the rotation of the placement basket 8 on the outer wall of the threaded sleeve 7 to improve the drying efficiency. When the placement basket 8 rotates to a suitable position, we can slide on the inner wall of the limit groove 10 through the limit block 9 on the outer wall of the placement basket 8. The design purpose of this step is to drive the limit lifting and lowering of the placement basket 8 to ensure that the medicine will not be damaged due to the movement of the basket during the drying process. After the above steps are completed, we can start the heating wire 1 5 and the heating wire 2 11 at the same time. The activation of the heating wire 1 5 and the heating wire 2 11 is to generate heat inside the box 1 and further increase the drying speed. At the same time, the reciprocating screw 3 drives the fan blade 6 to rotate, so that the heat generated by the heating wire circulates inside the box 1. This design not only improves the efficiency of drying, but also ensures that the medicine is evenly heated during the entire drying process.

[0033] Reference Figure 1 , Figure 2 and Figure 3The outer wall of the box body 1 is fixedly connected with a support frame 21, and the upper surface of the support frame 21 is fixedly connected with a fixed box 12; a filter plate 13 is slidably connected inside the fixed box 12, and a filter plate 2 14 is slidably connected directly below the filter plate 13; a circulation pump 15 is fixedly connected to the upper surface of the box body 1, a connecting pipe 16 is fixedly connected to the input end of the circulation pump 15, and a connecting pipe 2 17 is fixedly connected to the output end of the circulation pump 15; one end of the connecting pipe 16 is arranged through the inside of the box body 1, and the connecting pipe 2 17 is arranged through the inside of the fixed box 12; a plurality of circulation pipes 18 are arranged through the lower surface of the fixed box 12, and a plurality of circulation pipes 18 are arranged through the lower side of the inside of the box body 1; a protective door 19 is rotatably connected to the outer wall of the box body 1, and a perspective window 20 is fixedly connected to the inside of the protective door 19;

[0034] Specifically, first, a circulation pump 15 is provided inside the oven, and its main function is to circulate the heat energy inside the box 1. Through the operation of the circulation pump 15, the heat energy can be transferred from the inside of the box 1 to the connecting pipe 1 16, and then the heat energy is transferred to the connecting pipe 2 17. This design enables the heat energy to be efficiently transferred inside the oven, avoiding the waste of heat energy. Next, the connecting pipe 2 17 transfers the heat energy to the inside of the fixed box 12. Inside the fixed box 12, two filter plates 1 13 and filter plate 2 14 are provided. The function of these two filter plates is to filter out impurities in the heat energy and ensure the cleanliness of the heat energy. After filtering, the heat energy is then transferred to the inside of the box 1 through multiple circulation pipes 18. Inside the box 1, a fan blade 6 is provided. The function of the fan blade 6 is to circulate the clean heat energy into the inside of the box 1 again. In this way, the heat energy forms a circulating flow process inside the oven, thereby improving the heat energy utilization rate of the oven.

[0035] Working principle: when the medicine needs to be dried in the oven, the medicine is first placed inside the placement basket 8, and then the motor 2 is started to drive the reciprocating screw rod 3 to rotate inside the box body 1, so as to achieve the effect of driving the placement basket 8 on the outer wall of the threaded sleeve 7 to rotate, and then the limit block 9 on the outer wall of the placement basket 8 slides on the inner wall of the limit groove 10, so as to achieve the effect of driving the placement basket 8 to limit and lift, and at the same time, the heating wire 1 5 and the heating wire 2 11 are started, and the fan blades 6 are driven to rotate by the reciprocating screw rod 3, so that the heat generated by the heating wire 1 5 and the heating wire 2 11 circulates inside the box body 1, so as to achieve the effect of quickly drying the medicine;

[0036] At the same time, by starting the circulation pump 15, the heat energy inside the box body 1 is transmitted to the connecting pipe 2 17 through the circulating pump 15 through the connecting pipe 16, and then transmitted to the fixed box 12 through the connecting pipe 2 17, and then filtered through the filter plate 13 and the filter plate 2 14 inside the fixed box 12. At this time, the clean heat energy is reheated and circulated into the box body 1 through the fan blades 6 on the lower side of the box body 1 through multiple circulation pipes 18, thereby improving the thermal energy utilization rate of the oven and reducing energy consumption (it should be noted that: the filter plate 13 is made of activated carbon plate; the filter plate 2 14 is made of molecular sieve plate).

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
