Description

Technical Field

[0001] This utility model relates to the field of hot air circulating oven technology, and in particular to a hot air circulating oven for processing traditional Chinese medicine. Background Technology

[0002] An oven is a device used in the processing of traditional Chinese medicine to dry the herbs. When using a hot air circulating oven, the herbs are placed on baffles that are evenly arranged inside the support frame. Then the support frame is placed inside the oven body, so that the air blown out by the fan is heated by the electric heating rod, and the hot air circulates inside the oven body, which facilitates the drying of the herbs.

[0003] The inventors discovered in their daily work that hot air circulating ovens still have at least the following problems: When using a hot air circulating oven, the Chinese medicine is placed on baffles that are evenly arranged inside the support frame, and then the support frame is placed inside the oven body. The air blown out by the fan is heated by the electric heating rod, so that the hot air circulates inside the oven body, which is convenient for drying the Chinese medicine. However, in actual use, because the baffles are set separately inside the support frame, it is quite troublesome to take out the dried Chinese medicine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hot air circulating oven for processing traditional Chinese medicine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hot air circulating oven for processing traditional Chinese medicine, comprising an oven body, a connecting door hinged to one side of the oven body, a slide rail installed at the bottom of the inner wall of the oven body, a fan installed in the inner wall of the oven body, heating rods evenly installed on the inner wall of the oven body, the heating rods being positioned at the air outlet of the fan, a ventilation opening at the top of the oven body, a support frame slidably connected to the top of the slide rail, baffles evenly arranged on the inner wall of the support frame, a connecting device provided on one side of the support frame, the connecting device comprising a connecting frame, a threaded rod threadedly inserted into one side of the top of the connecting frame, the end of the threaded rod away from the connecting frame being rotatably inserted into one side of another connecting frame, a limiting rod slidably inserted into one side of the connecting frame, the other end of the limiting rod being rotatably inserted into one side of another connecting frame.

[0006] The effect achieved by the above components is as follows: when using the connecting device, the threaded rod can be manually rotated, and under the restriction of the limit rod, the distance between the two connecting frames can be changed, thereby completely removing the internal baffle of the support frame, which facilitates the storage of Chinese medicine.

[0007] Preferably, a rotating disk is fixedly connected to the surface of the threaded rod, and the rotating disk is disposed on the surface of the threaded rod near one end of the other connecting frame.

[0008] The effect achieved by the above components is that the rotation of the threaded rod can be well controlled by rotating the disc.

[0009] Preferably, a support block is fixedly connected to the top of another connecting frame, a first damping rod is fixedly connected to one side of the support block, a pressing plate is fixedly connected to the end of the first damping rod away from the support block, a first spring is sleeved on the surface of the first damping rod, one end of the first spring is fixedly connected to one side of the support block, and the end of the first spring near the pressing plate is fixedly connected to one side of the pressing plate.

[0010] The effect achieved by the above components is that when the threaded rod rotates to the appropriate position, it is pressed against one side of the rotating disk by the first spring pressing the pressing plate, which makes it easier to confine the threaded rod inside the connecting frame.

[0011] Preferably, a protrusion is uniformly and fixedly connected to the side of the rotating disk near the extrusion plate, and a rubber plate is provided at the end of the protrusion away from the rotating disk. The rubber plate and the side of the extrusion plate away from the first damping rod are fixedly connected.

[0012] The effect achieved by the above components is that when the extrusion plate is pressed against the rotating disk, the protrusion is pressed against one side of the rubber plate, which causes the rubber to be deformed by compression, thereby making it easier to restrict the extrusion plate to one side of the rotating disk.

[0013] Preferably, a second damping rod is fixedly connected between the two connecting frames, and a second spring is sleeved on the surface of the second damping rod. The two ends of the second spring are respectively fixedly connected to the side of the connecting frame near the second damping rod.

[0014] The effect achieved by the above components is that the connecting frame can be pulled relative to each other by the second spring, which makes it easier to keep the two connecting frames together.

[0015] Preferably, a U-shaped sleeve is fitted on the top of each of the two connecting frames, and the U-shaped sleeve is disposed on the top of the connecting frame.

[0016] The effect achieved by the above components is to fit the U-shaped sleeve on top of the two connecting frames, which makes it easier to restrain the two connecting frames together.

[0017] Preferably, a third damping rod is fixedly connected to the top of the connecting frame, the top of the third damping rod is fixedly connected to the bottom of the U-shaped sleeve, a third spring is sleeved on the surface of the third damping rod, one end of the third spring is fixedly connected to the top of the connecting frame, and the end of the third spring near the U-shaped sleeve is fixedly connected to the bottom of the U-shaped sleeve.

[0018] The effect achieved by the above components is that, since only the top of the connecting frame is fixedly connected to the third damping rod, the U-shaped sleeve is pulled towards the connecting frame by the third spring, which makes it easy to put the U-shaped sleeve on the top of the two connecting frames.

[0019] Preferably, the U-shaped sleeve has notches on both sides, and a limit strip is slidably connected to the inner wall of the notch. A fourth damping rod is fixedly connected to one side of the inner wall of the notch. The end of the fourth damping rod away from the notch is fixedly connected to one side of the limit strip. A fourth spring is sleeved on the surface of the fourth damping rod. One end of the fourth spring is fixedly connected to one side of the inner wall of the notch, and the end of the fourth spring near the limit strip is fixedly connected to the bottom of the limit strip.

[0020] The effect achieved by the above components is that the limiting strip is pulled towards the inner wall near the notch by the fourth spring, thereby pressing the bottom of the limiting strip against the top of the connecting frame, so that the U-shaped sleeve is moved away from the top surface of the two connecting frames.

[0021] In this invention, by setting a connecting device, when using the connecting device, the threaded rod is manually controlled to rotate. Under the restriction of the limiting rod, the distance between the two connecting frames can be changed, thereby completely removing the internal baffle of the support frame, which facilitates the storage of Chinese medicine.

Detailed Implementation

[0027] Example 1, such as Figure 1-4 As shown, a hot air circulating oven for processing traditional Chinese medicine has a connecting door 2 hinged to one side of the oven body 1. A slide rail 3 is installed at the bottom of the inner wall of the oven body 1. A fan 4 is installed in the inner wall of the oven body 1. Electric heating rods 5 are evenly installed on the inner wall of the oven body 1 and are located at the air outlet of the fan 4. A ventilation opening 6 is provided at the top of the oven body 1. A support frame 7 is slidably connected to the top of the slide rail 3. Baffles 8 are evenly arranged on the inner wall of the support frame 7. A connecting device 9 is provided on one side of the support frame 7. When using the hot air circulating oven, the traditional Chinese medicine is placed on the baffles 6 evenly arranged inside the support frame 7. Then, the support frame 7 is placed inside the oven body 1, so that the air blown out by the fan 4 is heated by the electric heating rods 5, and the hot air circulates inside the oven body 1, which facilitates the drying of the traditional Chinese medicine.

[0028] Reference Figures 2 to 4The connecting device 9 includes a connecting frame 901. A threaded rod 902 is threadedly inserted into one side of the top of the connecting frame 901. One end of the threaded rod 902, away from the connecting frame 901, is rotatably inserted into one side of another connecting frame 901. A limiting rod 903 is slidably inserted into one side of the connecting frame 901. The other end of the limiting rod 903 is rotatably inserted into one side of another connecting frame 901. When using the connecting device 9, the threaded rod 902 is manually rotated. Under the restriction of the limiting rod 903, the distance between the two connecting frames 901 can be changed, thereby allowing the internal baffle 8 of the support frame 7 to be completely removed, facilitating the storage of traditional Chinese medicine. A rotating disk 904 is fixedly connected to the surface of the threaded rod 902. The rotating disk 904 is located near the threaded rod 902. The surface of one end of the connecting frame 901 allows the rotation of the threaded rod 902 to be well controlled by the rotating disk 904. A support block 905 is fixedly connected to the top of the other connecting frame 901. A first damping rod 906 is fixedly connected to one side of the support block 905. A pressing plate 908 is fixedly connected to the end of the first damping rod 906 away from the support block 905. A first spring 907 is sleeved on the surface of the first damping rod 906. One end of the first spring 907 is fixedly connected to one side of the support block 905, and the end of the first spring 907 near the pressing plate 908 is fixedly connected to one side of the pressing plate 908. When the threaded rod 902 rotates to the appropriate position, the first spring 907 presses the pressing plate 908 against one side of the rotating disk 904. To facilitate confining the threaded rod 902 within the connecting frame 901, a protrusion 910 is uniformly fixedly connected to the side of the rotating disk 904 near the extrusion plate 908. A rubber plate 909 is provided at the end of the protrusion 910 away from the rotating disk 904. The rubber plate 909 and the side of the extrusion plate 908 away from the first damping rod 906 are fixedly connected. When the extrusion plate 908 presses against the rotating disk 904, the protrusion 910 presses against one side of the rubber plate 909, causing the rubber to be deformed, thus facilitating the confinement of the extrusion plate 908 to one side of the rotating disk 904. A second damping rod 911 is fixedly connected between the two connecting frames 901. A second spring 912 is sleeved on the surface of the second damping rod 911. The two ends of the second spring 912 are... The connecting frame 901 is fixedly connected to the side near the second damping rod 911. The connecting frame 901 can be pulled relative to each other by the second spring 912, thus confining the two connecting frames 901 together. A U-shaped sleeve 913 is fitted onto the top of each connecting frame 901, further confining them together. A third damping rod 914 is fixedly connected to the top of each connecting frame 901, with its top fixedly connected to the bottom of the U-shaped sleeve 913. A third spring 915 is fitted onto the surface of the third damping rod 914, with one end of the third spring 915 fixedly connected to the top of the connecting frame 901.The third spring 915 is fixedly connected to the bottom of the U-shaped sleeve 913 at one end near the U-shaped sleeve 913. Since only the top of the connecting frame 901 is fixedly connected to the third damping rod 914, the third spring 915 pulls the U-shaped sleeve 913 towards the connecting frame 901, making it easy to fit the U-shaped sleeve 913 onto the top of the two connecting frames 901. Notches 916 are provided on both sides of the U-shaped sleeve 913. Limit strips 917 are slidably connected to the inner wall of the notch 916. A fourth damping rod 918 is fixedly connected to one side of the inner wall of the notch 916. One end of the fourth damping rod 918, away from the notch 916, is fixedly connected to one side of the limiting strip 917. A fourth spring 919 is fitted onto the surface of the fourth damping rod 918. One end of the fourth spring 919 is fixedly connected to one side of the inner wall of the notch 916, and the end of the fourth spring 919 near the limiting strip 917 is fixedly connected to the bottom of the limiting strip 917. By pulling the limiting strip 917 towards the inner wall near the notch 916 through the fourth spring 919, the bottom of the limiting strip 917 is pressed against the top of the connecting frame 901, thus keeping the U-shaped sleeve 913 away from the top surfaces of the two connecting frames 901.

[0029] Working principle: When using the hot air circulating oven, the Chinese medicine is placed on the baffles 6 evenly arranged inside the support frame 7. Then, the support frame 7 is placed inside the oven body 1, so that the air blown by the fan 4 is heated by the electric heating rod 5, causing the hot air to circulate inside the oven body 1. This facilitates the drying of the Chinese medicine. When using the connecting device 9, the rotation of the threaded rod 902 can be well controlled by the rotating disk 904. Under the restriction of the limit rod 903, the distance between the two connecting frames 901 can be changed. When the threaded rod 902 rotates to the appropriate position, the first spring 907 presses the extrusion plate 908 against one side of the rotating disk 904. When the extrusion plate 908 presses against the rotating disk 904, the protrusion 910 presses against one side of the rubber plate 909, which causes the rubber to be deformed, thus facilitating the drying of the Chinese medicine. The extrusion plate 908 is confined to one side of the rotating disk 904, which facilitates the confinement of the threaded rod 902 inside the connecting frame 901, thereby allowing the internal baffle 8 of the support frame 7 to be completely removed, facilitating the storage of Chinese medicine. The connecting frame 901 can be pulled relative to each other by the second spring 912, which facilitates the confinement of the two connecting frames 901 together. Since only the top of the connecting frame 901 is fixedly connected to the third damping rod 914, the U-shaped sleeve 913 is pulled towards the connecting frame 901 by the third spring 915, which facilitates the fitting of the U-shaped sleeve 913 onto the top of the two connecting frames 901. The limiting strip 917 is pulled towards the inner wall of the notch 916 by the fourth spring 919, which causes the bottom of the limiting strip 917 to be pressed against the top of the connecting frame 901, thus keeping the U-shaped sleeve 913 away from the top surface of the two connecting frames 901.

[0030] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process. The oven model mentioned in this case is DFS180W.
