Description

Technical Field

[0001] This application relates to the technical field of freeze dryers, and more particularly to a household freeze dryer. Background Technology

[0002] A home freeze dryer is a miniaturized device designed based on freeze-drying technology. It is specifically designed for dehydrating and preserving food, medicinal herbs, pet food, and other materials in a home setting. Its core principle is to remove moisture from the material by directly converting it from solid ice to gas in a vacuum environment through three steps: low-temperature pre-freezing, vacuum sublimation, and desorption drying. The final product retains the original nutrition, flavor, and shape of the material.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: In the prior art, the racks of household freeze dryers are mostly installed inside the main body of the equipment using fixed connections or complex bolt connections. During long-term use, food scraps, juices, and other contaminants are easily left on the surface of the racks. The fixed installation structure makes the disassembly of the racks cumbersome and difficult to clean. The residual contaminants not only affect the freeze-drying quality and hygiene safety of the food, but may also breed bacteria, leading to internal contamination of the equipment. Utility Model Content

[0004] To facilitate the disassembly and cleaning of the rack, this application provides a household freeze dryer.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model, by incorporating components such as a pressing block, a locking block, and a rotating rod, allows for easy removal of the rack from its fixed position simply by pressing the pressing block when cleaning is required. The rack can then be pulled directly out of the main body using the handle. Since the locking block is angled, it can be pushed back into place after cleaning to re-lock and secure the rack.

[0013] 2. This utility model, by incorporating components such as a sliding cylinder, rotating plate, and damping spring, allows the shock absorption mechanism to convert vibration energy into elastic potential energy and gradually release it when the equipment experiences longitudinal vibration, through the linkage of the mechanical structure and the deformation of the damping spring. This significantly reduces the transmission of vibration to the main body and internal components, preventing components from becoming loose or fatigued due to long-term vibration, thus significantly improving the stability of equipment operation and extending the overall service life of the equipment.

[0020] Please see Figure 3As shown, a connecting rod 23 is fixedly connected to the back of the pressing block 21, a connecting block 231 is fixedly connected to the back of the connecting rod 23, and a spring telescopic column 232 is fixedly connected to the back of the connecting block 231. The spring telescopic column 232 can be reset after the pressing block 21 is displaced. The back of the spring telescopic column 232 is fixedly connected to the back of the inner wall of the main body 1.

[0021] Please see Figure 4 As shown, a rotating plate 32 is rotatably connected to the inner wall of the slot, and the outer wall of the rotating plate 32 is rotatably connected to the bottom of the sliding block 11. A connecting plate 33 is fixedly connected to the back of the sliding plate 311, and a damping spring 34 is fixedly connected to the back of the connecting plate 33.

[0022] Please see Figure 3 As shown, a slide rail 24 is fixedly connected to the top of the inner wall of the fixed box 2. The outer wall of the slide rail 24 is slidably connected to the inner wall of the snap-fit ​​block 241. A rotating groove is provided on the back of the snap-fit ​​block 241, and a rotating rod 25 is rotatably connected to the inner wall of the rotating groove.

[0023] Please see Figure 4 As shown, the back of the damping spring 34 is fixedly connected to the back of the inner wall of the sliding cylinder 12. There are two damping springs 34, which are symmetrically arranged. There are two rotating plates 32. All the parts related to the sliding plate 311 mentioned above are two in number, and the whole set is arranged in two symmetrical sets.

[0024] Please see Figure 2 , Figure 3 As shown, the outer wall of the rotating rod 25 is rotatably connected to the inner wall of the connecting block 231. There are two sliders 221, which are symmetrically arranged. There are also two rotating rods 25, which are symmetrically arranged with the connecting block 231 as the center.

[0025] The implementation principle of a household freeze dryer according to an embodiment of this application is as follows: The placement rack 222 is slidably connected to two slide rails 22 on the inner wall of the main body 1 via two sliders 221 at the bottom. The corresponding locking grooves of the two sliders 221 and the two locking blocks 241 form a locking engagement. At this time, the placement rack 222 is stably fixed inside the main body 1 and can normally carry food for freeze drying. When it is necessary to clean the placement rack 222, press the pressing block 21 on the front of the fixing box 2. The pressing block 21 drives the connecting rod 23 and the connecting block 231 on the back to move backward. The connecting block 231 compresses the spring telescopic column on its back. 232. Simultaneously, the backward movement of the connecting block 231 causes the two rotating rods 25 connected to it to rotate synchronously. Since the two rotating rods 25 are symmetrically arranged with the connecting block 231 as the center, the two rotating rods 25 will pull the corresponding locking block 241 to slide along the slide rail 24 away from the slider 221 until the locking block 241 is completely disengaged from the locking groove of the slider 221. At this time, the fixation between the slider 221 and the placement rack 222 is released, and the placement rack 222 can be pulled out of the main body 1 for cleaning along the slide 22. After cleaning, the slider 221 at the bottom of the placement rack 222 is aligned with the slide 22 and pushed. The slider 221 is moved until it returns to its initial position. Because the locking block 241 has a sloping surface on its front, it retracts as the slider 221 moves continuously. Then, the spring telescopic column 232 resets under elastic force, pushing the connecting block 231, connecting rod 23, and pressing block 21 forward. The connecting block 231 drives the rotating rod 25 to rotate in the opposite direction, pushing the locking block 241 to slide along the slide rail 24 and re-engage in the locking groove of the slider 221, completing the fixed reset of the placement frame 222. The longitudinal vibration generated by the equipment's operation is transmitted from the main body 1 to the sliding block 11 at the bottom, and the sliding block 11 distributes the vibration... The force is transmitted to the two symmetrical rotating plates 32 that are rotatably connected to their bottom. The two rotating plates 32 rotate under the force, and their other ends push the sliding plate 311 to slide horizontally along the connecting column 31 on the fixed plate 3. The sliding of the two sliding plates 311 will drive the connecting plate 33 on the back to move synchronously, thereby compressing or stretching the damping spring 34 connected to it. The damping spring 34 absorbs the energy generated by the vibration through its own elastic deformation, and gradually dissipates the energy through the damping effect, thereby greatly reducing the transmission of longitudinal vibration to the main body 1 and the internal structure, and achieving the effect of shock absorption and protection.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
