Description

Technical Field

[0001] This utility model relates to the field of soymilk makers, and in particular to a filter screen structure and a soymilk maker. Background Technology

[0002] Soy milk makers, whether for home or commercial use, typically consist of a blade inside a container. Soybeans are placed in the container with a specific ratio of water, and the blades grind them into a paste. To quickly separate the soybean pulp from the soy milk, a stainless steel screen is usually placed around the blade inside the container. This screen is snapped into the bottom of the container. Soybeans are placed inside the screen, and after grinding, the soybean pulp remains inside while the soy milk can be poured out, achieving separation. The stainless steel screens commonly used in soy milk makers are typically 30-60 mesh. This allows some finer soybean pulp to pass through the mesh, affecting the texture of the soy milk. Using higher mesh stainless steel screens, however, is prone to clogging, making cleaning difficult once the mesh is clogged. Therefore, in general use, the stainless steel screen needs to be replaced regularly, resulting in high operating costs. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a filter screen structure and a soy milk maker.

[0004] This utility model is achieved using the following technical solution: a filter screen structure, comprising: A support frame, comprising a top support ring and a bottom support ring, wherein the top support ring and the bottom support ring are fixed together by a support strip; The net bag is a cylindrical shape with openings at the top and bottom. It is fitted onto the support frame. The top of the net bag covers the top support ring and is flipped over. The bottom of the net bag is fitted onto the bottom support ring and is flipped over. Clamping blocks, wherein at least one pair of clamping blocks are provided and clamped and fixed on the top support ring for securing the net bag to the top support ring.

[0005] The net is placed inside the area enclosed by the supporting frame, with the top and bottom of the net folded outwards.

[0006] The net is fitted over the outside of the supporting frame, and the top and bottom of the net are folded inward.

[0007] The clamping block includes: The mounting base has a groove for fitting the outer edge of the top support ring; The card holder is fixed on the mounting base and extends upward. A locking groove is provided at the position where the card holder is flush with the top surface of the top support ring. The retaining ring, in the shape of a U, is fitted and locked in the engagement groove, with one end of the retaining ring away from the engagement groove bent downwards to meet the inner wall of the top support ring and extending towards the bottom support ring.

[0008] A soymilk maker, wherein a filter screen structure is placed inside the placement cavity of the soymilk maker.

[0009] The soymilk maker includes: A base is used to mount the motor. The base is fixed to the bottom of the placement cavity, and the motor shaft passes through the bottom of the placement cavity to mount the blade. The top opening of the placement cavity is used to place beans. A positioning ring is fixed inside the base and wrapped around the cutter head. The net is placed between the positioning ring and the bottom support ring. The bottom of the positioning ring is bent inward to form a platform that is flush with the bottom support ring.

[0010] The top cover fits over the opening of the placement cavity and seals the placement cavity.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0015] Reference Figure 1-3 A filter screen structure includes a support frame 1, which comprises a top support ring 11 and a bottom support ring 12, which are fixed together by support strips 13. Specifically, the top support ring 11, the bottom support ring 12, and the support strips 13 together form a cylindrical structure that runs vertically through the screen, and there is a distance between adjacent support strips 13. A more preferred approach is that the support strips 13 are evenly distributed on the top support ring 11, so that the gaps between adjacent support strips 13 are uniform, allowing the slurry to flow out through the gaps during use, thus separating the slurry from the soybean residue.

[0016] The support frame 1 is used to mount and support the net bag 2. The net bag 2 is a cylindrical shape with openings at the top and bottom. It is mounted on the support frame 1, with the top of the net bag 2 covering the top support ring 11 and flipped over, and the bottom of the net bag 2 mounting the bottom support ring 12 and flipped over. This ensures that the top and bottom of the net bag 2 are properly secured and supported by the top and bottom support rings 11 and 12. The net bag 2 is made of non-woven fabric or similar materials, with a mesh size of 50 mesh or higher, and it is easy to clean when the mesh becomes clogged. It only requires disassembly and washing. Both cleaning and replacement are simple and inexpensive.

[0017] The net bag 2 is fixed to the top support ring 11 by clamping blocks 3. At least one pair of clamping blocks 3 are provided and clamped and fixed to the top support ring 11 to secure the net bag 2 to the top support ring 11. The clamping blocks 3 in this application include at least a mounting base 31, with a groove on the mounting base 31 for fitting the outer edge of the top support ring 11. A retaining seat 32 is fixed to the mounting base 31 and extends upwards. A locking groove is formed at the position where the retaining seat 32 is flush with the top surface of the top support ring 11. A retaining spring 33 is used to engage and fix it within the locking groove. The retaining spring 33 is U-shaped, sleeved and locked within the locking groove, with one end of the retaining spring 33 bent downwards to connect with the inner wall of the top support ring 11 and extending towards the bottom support ring 12. This configuration, by inserting and pressing the net bag 2 against the top support ring 11 from the upper part, effectively clamps and secures the net bag 2.

[0018] In this embodiment, the net bag 2 can be placed inside the area enclosed by the support frame 1, with the top and bottom of the net bag 2 folded outwards to wrap around the top support ring 11 and the bottom support ring 12. That is, the support frame 1 is outside the net bag 2. Alternatively, the net bag 2 can be fitted over the support frame 1 with its top and bottom folded inwards, meaning the support frame 1 is inside the net bag 2. Whether the support frame 1 is inside or outside the net bag 2, it provides support for the net bag 2.

[0019] Reference Figure 1-4 When the filter screen structure of this embodiment is installed on a soymilk maker, the soymilk maker must include at least a base 4 for mounting a motor. The base 4 is fixed to the bottom of the placement chamber, and the motor shaft extends from the bottom of the placement chamber to mount the blade head 41. The top opening of the placement chamber is for placing beans. The blade head 41 rotates to crush the beans, thereby mixing the substances in the beans with water. The water is driven to rotate by the rotation of the blade head 41, ensuring thorough mixing.

[0020] A positioning ring 42 is also required inside the placement cavity. The positioning ring 42 is fixed inside the base 4 and wrapped around the cutter head 41. The net bag 2 is placed between the positioning ring 42 and the bottom support ring 12. The bottom of the positioning ring 42 is bent inward to form a platform that is flush with the bottom support ring 12.

[0021] The top cover 5 is closed at the opening of the placement cavity to seal the cavity during use, ensuring smooth pulping. In this embodiment, the optimal arrangement is for the top end face of the clamping block 3 to be higher than the end face of the top support ring 11, so that when the top cover 5 is closed, its end face presses firmly against the clamping block 3. This provides additional pressure to the support frame 1 and the assembly, preventing abnormal movement of the net bag 2 throughout the pulping process and ensuring smooth pulping.

[0022] To ensure that the upper cover 5 can be stably closed during the pulping process, at least one pair of latches 6 are fixed on the outer wall of the placement cavity. The edge of the upper cover 5 extends outward to form a latch. When the upper cover 5 is closed on the placement cavity, the latches 6 engage with the latch to seal the placement cavity.

[0023] Compared to existing technologies, the support frame 1 and the mesh bag 2 in this invention can be easily disassembled. In actual use, the physical connection between the support frame 1 and the mesh bag 2 relies solely on the clamping block 3, making disassembly, replacement, and cleaning much more convenient. Furthermore, the mesh bag 2 is made of fabric, allowing for finer filter pores, resulting in smoother filtered slurry. More importantly, even if the filter pores of the mesh bag 2 become clogged, it can be directly disassembled and soaked for cleaning. This cleaning method is simpler, provides better cleaning results than stainless steel filters, and conserves water.

[0024] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
