Description

Technical Field

[0001] The utility model relates to the technical field of food processing devices, and specifically relates to an inner container of a small food crusher. Background Technique

[0002] As a portable device for food processing, a small food crusher can quickly achieve food crushing and facilitate food production. Therefore, improving the performance of small food crushers has become the development direction of the industry.

[0003] Currently, existing small food crushers on the market usually have an inner container. A rotating blade is arranged in the middle of the inner container. After the food is placed in the inner container, the rotating blade is started, and the food in the inner container is chopped by the rotating blade to complete the crushing operation. For example, the food processing device disclosed in patent CN200720054057.5 has an inner container arranged in a housing, a top cover is arranged on the housing, a knife shaft is rotatably installed at the bottom of the inner container, the blade is located in the inner container, and the blade is arranged on the knife shaft and driven by a motor. The blade is an upper knife and a lower knife. The motor is arranged in the base, and an upper and lower clutch structure is arranged between the motor and the knife shaft. When in use, the housing is installed on the base, and the connection between the motor and the knife shaft is realized through the cooperation of the upper and lower clutch structures. At this time, the food to be crushed is placed in the inner container and the upper opening of the inner container is covered by the top cover. Then the motor is started, and the knife shaft is driven to rotate by the motor, so that the knife shaft can drive the blade to rotate in the inner container, thereby crushing the food located in the inner container to meet the food crushing requirements. However, during the food crushing process, since the food needs to contact and relatively rub against the inner wall of the inner container, it will be subjected to a circumferential force that causes its rotation during use. The existing inner container only has a limiting structure at the upper opening and lacks a bottom limiting structure. Under the action of its own gravity, the food will concentrate at the bottom of the inner container, resulting in torsional forces on the upper and lower parts of the inner container, which is likely to cause damage to the inner container. In addition, the side wall and the bottom wall of the existing inner container have the same thickness. However, when the food concentrates at the bottom of the inner container, the pressure on the bottom of the inner container increases and the wear caused by friction is also greater, which will shorten the service life of the inner container. Summary of the Invention

[0004] Aiming at the above problems existing in the prior art, the present invention aims to provide an inner container of a small food crusher, in which a thickening ring strip is arranged outside the bottom wall of the barrel body. At the same time, a plurality of lower limiting parts are arranged on the thickening ring strip. By increasing the thickness of the bottom wall of the barrel body through the thickening ring strip, the bottom bearing capacity of the inner container is stronger and the wear resistance is more durable, realizing the partition strengthening of the structure. In addition, the purpose of arranging a limiting structure at the bottom of the inner container is also achieved, so that the upper and lower parts of the inner container can be limited at the same time, thereby avoiding the problem that the upper and lower parts of the inner container are damaged due to torsional forces during use and extending the service life of the inner container.

[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following embodiments are combined with the attached Figure 1 to the attached Figure 4 to specifically elaborate on the technical solutions provided by the present utility model, but the following content is not a limitation of the present utility model.

[0029] Figure 1 is a structural diagram of an embodiment of the inner tank of a small food crusher of the present utility model; Figure 2 is an installation schematic diagram of a thickened ring strip and a lower limit portion of a preferred embodiment of the present utility model. As Figure 1 and Figure 2 shown, the inner tank of the small food crusher provided in this embodiment includes: a barrel body 1, a thickened ring strip 2, an upper limit portion 3 and a lower limit portion 4.

[0030] Specifically, the barrel body 1 is made of stainless steel, with higher material stability. Moreover, the inner surface of the barrel body 1 is a matte surface, which enhances the friction force on the inner surface of the barrel body 1, facilitating the relative movement between the food and the blade, and improving the food crushing efficiency. Additionally, during installation, the barrel opening of the barrel body 1 is arranged upwards, which is convenient for taking and placing food. At this time, the barrel bottom of the barrel body 1 is downwards, and a rotating shaft hole communicating with the barrel inner cavity is opened at the center of the barrel bottom, providing an installation space for the cutter shaft through the rotating shaft hole, enabling the blade subsequently installed in the inner tank to be installed on the cutter shaft and driven by the cutter shaft, realizing the crushing of the food in the barrel inner cavity of the barrel body 1 of the inner tank and meeting the use requirements.

[0031] Specifically, a thickened ring strip 2 is further provided at the barrel bottom of the barrel body 1. At this time, the thickened ring strip 2 is arranged in a ring shape, and the thickened ring strip 2 is arranged outside the bottom wall of the barrel body 1, and during the manufacturing process, the thickened ring strip 2 is attached to the bottom surface of the bottom wall of the barrel body 1, so that under the action of the thickened ring strip 2, not only can the thickness of the barrel bottom of the barrel body 1 be strengthened, with higher structural strength, better wear resistance, and stronger bearing capacity, but also the space interference of the thickened ring strip 2 on the inner cavity of the barrel body 1 can be avoided, ensuring the flatness of the inner surface of the inner cavity of the barrel body 1, and the structural design is more reasonable.

[0032] Specifically, the upper limit portion 3 is arranged on the outer side wall of the barrel opening of the barrel body 1 and extends radially along the barrel body 1, that is, a limiting structure is formed outside one end of the barrel opening of the barrel body 1 through the upper limit portion 3, ensuring that the upper part of the inner tank can be limited during installation and use, and maintaining the stability of the upper part of the inner tank.

[0033] Specifically, the lower limit portion 4 is provided on the outer bottom wall of the barrel body 1 or on the thickening ring strip 2, that is, a limiting structure is also formed at the lower part of the barrel body 1 through the lower limit portion 4, ensuring that the lower part of the inner container can be limited during installation and use, maintaining the stability of the lower part of the inner container, so that corresponding limiting structures are provided at both the upper and lower parts of the inner container, thus avoiding the problem that the upper and lower parts of the inner container are easily damaged due to long-term torsional forces when only a limiting structure is provided at the upper part of the inner container in the prior art, and prolonging the service life of the inner container. Moreover, the lower limit portion 4 extends downward along the axial direction of the barrel body 1, which facilitates inserting the lower limit portion 4 into the corresponding mating structure along the vertical direction when installing the inner container, making the installation more convenient. At the same time, under the action of the gravity of the inner container and the food in the inner container, the lower limit portion 4 is pressed against the corresponding mating structure, and it is not easy to have the problem of detachment, with higher safety guarantee.

[0034] More specifically, the inner container further includes a shaft sleeve 11. At this time, the shaft sleeve 11 is arranged in a cylindrical shape, making the shaft sleeve 11 a hollow shaft structure. And the shaft sleeve 11 is arranged inside the barrel body 1, and the lower end of the shaft sleeve 11 is fixedly connected to the bottom wall of the barrel body 1. Preferably, the shaft sleeve 11 is also made of stainless steel, and the lower end of the shaft sleeve 11 is welded to the bottom wall of the barrel body 1, realizing the stable installation of the shaft sleeve 11 inside the barrel body 1. At the same time, the shaft sleeve 11 is coaxially arranged outside the rotating shaft hole, that is, a protective blocking structure is formed outside the rotating shaft hole through the shaft sleeve 11, increasing the height of the rotating shaft hole inside the barrel body 1, so that there is a height difference between the bottom of the barrel body 1 and the rotating shaft hole, thus avoiding the problem that a large amount of food leaks from the rotating shaft hole during subsequent food crushing, and the structural design is more reasonable.

[0035] More specifically, the inner cavity of the shaft sleeve 11 is arranged in a stepped shape, and it is set that the inner diameter of the lower end of the shaft sleeve 11 is larger than the inner diameter of the upper end of the shaft sleeve 11, that is, the space of the inner cavity of the lower part of the shaft sleeve 11 is larger, which is convenient for the installation of structures such as bearings on the cutter shaft, and the space utilization is more reasonable.

[0036] Figure 3 This is a structural diagram of the side installation part of a preferred embodiment of the present invention. As Figures 1 to 3 shown, the inner container further includes a side installation part 5. At this time, the side installation part 5 is arranged along the axial direction of the barrel body 1 and fixedly installed on an outer side wall of the barrel body 1, that is, an installation structure is formed at the side part of the barrel body 1 through the side installation part 5, providing conditions for the installation of the inner container in the housing of the food crusher. And the side installation part 5 is arranged along the axial direction of the barrel body 1, making the length of the side installation part 5 longer, which can not only strengthen the structural strength of the barrel body 1, but also make the connection strength between the side installation part 5 and the barrel body 1 higher, and more stable after installation. At the same time, a plurality of installation holes 51 arranged at intervals are opened on the side installation part 5, so that when installing the inner container, it can be fixed by passing threaded fasteners such as screws through the installation holes 51, and the disassembly and assembly are more convenient.

[0037] More specifically, each mounting hole 51 on the side mounting portion 5 is a strip hole arranged axially along the barrel body 1, so that the mounting hole 51 has an idle stroke in the axial direction of the barrel body 1, so that when the inner pot is installed in the food grinder shell, the installation height of the inner pot can be adjusted, and the adaptability is better.

[0038] More specifically, the side mounting part 5 is a plate-shaped stamping part, that is, formed by stamping and bending a flat plate, which is more convenient to process. At this time, one side of the side mounting part 5 is bent to form a connecting piece 52. When installing, the connecting piece 52 of the side mounting part 5 is attached to the outer wall of the barrel body 1 and welded to the outer wall of the barrel body 1, which increases the contact area between the side mounting part 5 and the barrel body 1, thereby improving the stability and reliability of the side mounting part 5 installed on the barrel body 1, and the overall structure is more stable.

[0039] More specifically, two cutting grooves 53 are opened on one side of the side mounting portion 5 and along its length direction, and the two cutting grooves 53 are arranged at intervals, that is, one side of the side mounting portion 5 is divided into three sections by the two cutting grooves 53. Preferably, the uppermost and lowermost sections obtained by dividing the side mounting portion 5 are classified as a group of connecting pieces 52, and the middle section obtained by dividing is classified as a group of connecting pieces 52. When the bending operation is performed, the bending directions of the two groups of connecting pieces 52 are set to be opposite, so that the two groups of connecting pieces 52 on one side of the side mounting portion 5 can extend in opposite directions, so that when the side mounting portion 5 is connected to the outer wall of the barrel body 1, both sides of the side mounting portion 5 can be subjected to force, which further improves the stability and reliability of the side mounting portion 5 during installation, and the structural design is more reasonable.

[0040] More specifically, a positioning notch 54 is provided on the side of the side mounting portion 5 away from the barrel body 1, so that when the inner pot is subsequently installed in the food grinder housing, it can be quickly positioned through the positioning notch 54, thereby improving the installation efficiency and making disassembly and assembly more convenient.

[0041] Figure 4 This is a structural diagram of a thickened ring strip of a preferred embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 4As shown, a number of perforations 21 arranged at intervals are evenly formed in a ring array on the thickened coil strip 2, realizing the uniform distribution of the perforations 21 on the thickened coil strip. Preferably, the lower limiting part 4 is arranged on the thickened coil strip 2. At this time, the lower limiting part 4 is a number of positioning rods corresponding to the perforations 21 one by one, and the axial direction of each positioning rod is consistent with the axial direction of the barrel body 1. At the same time, the longitudinal section of each positioning rod is arranged in a "T" shape, so that each positioning rod has a large head end and a small head end, ensuring that the outer wall of each positioning rod is arranged in a stepped shape. And a concave groove 22 is arranged on the thickened coil strip 2 and at each perforation 21. The perforation 21 penetrates through the corresponding concave groove 22, and a counterbore is formed at the corresponding perforation 21 through the concave groove 22, so that a limiting step can be formed between the concave groove 22 and the perforation 21. When the positioning rod is installed on the thickened coil strip 2 subsequently, the small head end of the positioning rod can penetrate through the perforation 21. At the same time, the large head end of the positioning rod is located in the concave groove 22. When the thickened coil strip 2 is installed on the bottom of the barrel body 1, the large head end of the positioning rod can be received in the concave groove 22 and abutted against the bottom of the barrel body 1. This can not only ensure that the end face of the thickened coil strip 2 can completely fit on the bottom wall of the barrel body 1, ensuring that the thickened coil strip 2 can completely support the barrel body 1, but also enable the positioning rod to be stably installed on the thickened coil strip 2 without falling off, with higher structural strength.

[0042] More specifically, the upper limiting part 3 arranged at one end of the barrel mouth of the barrel body 1 further includes a number of limiting rods. At this time, one end of each limiting rod is welded to the outer side wall of one end of the barrel mouth of the barrel body 1, so that the limiting rod can be subsequently inserted into the card slot on the housing of the food crusher to realize the limitation of the upper part of the inner liner. The structure is simple and the manufacturing cost is low.

[0043] More specifically, the center of the bottom of the barrel body 1 protrudes towards the inner cavity of the barrel, so that the center height of the bottom of the barrel body 1 is higher and the outer edge height is lower, thereby avoiding the accumulation of food around the shaft sleeve 11 and better concentrating at the outer edge, facilitating the crushing of food by the blade. In addition, the inner bottom wall of the barrel body 1 is arranged in an inclined plane, so that the inner bottom wall of the barrel is in a continuous inclined state, facilitating the movement and aggregation of food, and the structural design is more reasonable.

[0044] The inner container of the small food crusher provided in this embodiment includes a barrel body 1, a thickening ring strip 2, an upper limiting part 3, and a lower limiting part 4; by arranging the thickening ring strip 2 outside the bottom wall of the barrel body 1, at the same time, arranging the lower limiting part 4 on the bottom wall of the barrel body 1 or the thickening ring strip 2, and arranging the upper limiting part 3 on the barrel opening of the barrel body 1, the thickening ring strip 2 not only increases the thickness of the bottom wall of the barrel body 1, making the bearing capacity of the bottom of the inner container stronger and the wear resistance effect better, thus extending the service life, and moreover, the thickening ring strip 2 is only arranged in the area where the barrel body 1 is worn more, realizing the sectional strengthening of the structure and avoiding the waste of materials. At the same time, through the arrangement of the upper limiting part 3 and the lower limiting part 4, the upper and lower parts of the inner container can be limited simultaneously, effectively avoiding the problem that the upper and lower parts of the inner container are easily damaged due to the torsional force during use, and further extending the service life of the inner container.

[0045] The above is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be able to realize that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
