Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a food chopper, and more particularly to an auxiliary chopping mechanism for a food chopper. Background Technology

[0002] A food chopper is a kitchen tool used to quickly chop, blend, or mix ingredients, improving food preparation efficiency.

[0003] An existing shredder structure, such as the novel shredder disclosed in the Chinese Patent Database (application number: 201820175845.8), includes a base, a mixing tank, mixing blades, and a lid. A drive motor is installed inside the base, connected to a transmission shaft. The transmission shaft extends from the top of the base and engages with a mixing blade holder inside the mixing tank. The mixing blade holder has mixing blades. The key feature is that the top of the base has a circular hollow column with two L-shaped locking grooves on its surface, the tops of which are flush with the top of the hollow column. The lower part of the outer wall of the mixing tank has two locking blocks that match the locking grooves. A locking element is provided on each side of the upper part of the mixing tank wall. The edge of the lid has a fitting element that engages with the locking elements to lock the lid in place. The lid also has a feed inlet connected to a sealing cap. The mixing tank wall also has an elastic top element, and the edge of the lid has a fitting element that allows the lid to separate from the mixing tank under the action of the elastic top element.

[0004] In the initial chopping stage, the ingredients are relatively large and move upwards significantly under the action of the mixing blades. This causes some ingredients to stick to the top wall of the lid and the inner wall of the upper part of the mixing bowl, preventing them from being fully chopped. As a result, the final product has uneven coarseness and poor chopping effect. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an auxiliary chopping mechanism for a food chopper that provides a better chopping effect.

[0006] The objective of this utility model can be achieved through the following technical solution: An auxiliary chopping mechanism for a food chopper includes a base, a mixing tank fixed on the base, and a lid on top of the mixing tank. A horizontally arranged connecting arm is fixed above the lid, with one end of the connecting arm hinged to the base. The lid is opened or closed by swinging the connecting arm. The characteristic feature is that a bushing is vertically fixed between the connecting arm and the lid. The upper end of the bushing passes through the connecting arm, and the lower end extends into the lid. The bushing and the mixing tank are coaxially arranged. A rotating shaft matching the bushing is vertically inserted into the bushing, and the rotating shaft and the bushing form an axial limiting and circumferential rotation relationship. The upper end of the rotating shaft extends out of the bushing, and the lower end extends into the lid and is fixedly connected to a connecting frame. A scraper plate one and a scraper plate two are fixed on the connecting frame, and scraper plate one and scraper plate two are respectively used to scrape the inner side of the top wall of the lid and the inner side wall of the upper end of the mixing tank.

[0007] In the initial stage of chopping ingredients, the rotating shaft is manually rotated to drive scraper one and scraper two to scrape off large pieces of ingredients attached to the top wall of the bucket lid and the inner wall of the upper end of the mixing bucket. This ensures that the ingredients can be fully chopped by the chopping components in the mixing bucket, so that the ingredients can be chopped to a basically uniform size, effectively improving the chopping effect of the chopper.

[0008] In the aforementioned auxiliary chopping mechanism of the food chopper, the top of the lid has a vertically arranged connecting cylinder, and the connecting cylinder and the lid are coaxially arranged. The lid is fixed to the connecting arm via the connecting cylinder, and a seal is formed between the upper end of the connecting cylinder and the connecting arm. The connecting cylinder is sleeved outside the bushing, and the connecting arm has an upper through hole through which the upper end of the bushing passes, with the upper end of the bushing sealing the upper opening of the through hole. The connecting cylinder sleeves outside the bushing, and the upper end of the bushing directly seals the upper opening of the through hole, reducing the sealing structure required for bushing installation. This design offers advantages such as simple structure and convenient installation.

[0009] In the aforementioned auxiliary chopping mechanism of the food chopper, the connecting cylinder and the lid are integrated into one piece for easier installation.

[0010] In the above-mentioned auxiliary chopping mechanism of the food chopper, the upper end of the bushing is a ring-shaped limiting seat, which presses against the upper side of the connecting arm and closes the upper opening of the upper through hole; the lower end of the bushing is fitted with and fixed with a limiting ring, which presses against the inner side of the top wall of the bucket lid. In this way, the bushing can be installed by screwing in the bushing and installing the limiting ring, making the assembly more convenient.

[0011] In the aforementioned auxiliary chopping mechanism of the food chopper, a vertically penetrating positioning groove is provided on the upper edge of the through hole. A limiting block matching the positioning groove is formed on the bottom wall of the limiting seat, and the limiting block is inserted into the positioning groove. The limiting block and the positioning groove cooperate to further limit the bushing in the circumferential direction, thereby enhancing its positioning stability and strength.

[0012] In the aforementioned auxiliary chopping mechanism of the food chopper, a limiting component is fixedly connected to the upper end of the rotating shaft, and the limiting component presses against a limiting seat; the outer wall of the lower end of the rotating shaft has an annular shoulder surface, which is located below the bushing, and the shoulder surface can abut against the bushing or the limiting ring to restrict the upward movement of the rotating shaft. This design allows the rotating shaft to slide up and down a smaller distance, reducing the requirements for processing and assembly without affecting the normal rotation of the rotating shaft.

[0013] In the aforementioned auxiliary chopping mechanism of the food chopper, a handle is provided on the rotating shaft. The handle includes a horizontally arranged connecting rod, one end of which has a vertically extending connecting hole. The upper end of the rotating shaft is inserted into and fixed in the connecting hole, and the aforementioned limiting member is the end of the connecting rod with the connecting hole. This design allows for easier rotation of the rotating shaft.

[0014] In the above-mentioned auxiliary chopping mechanism of the food chopper, the connecting frame includes a long plate-shaped backing plate, and the lengths of both the scraper and the backing plate extend horizontally along the radial direction of the bucket lid. The scraper is attached to and fixed to one side of the backing plate.

[0015] In the above-mentioned auxiliary chopping mechanism of the food chopper, the connecting frame also includes a long plate-shaped backing plate 2. The scraper 2 and the backing plate 2 both extend vertically, and the scraper 2 is attached to and fixed to one side of the backing plate 2.

[0016] With the cooperation of the first and second backing plates, the positioning stability and strength of the first and second scrapers can be enhanced, making the purpose of this application more stable.

[0017] Compared with existing technologies, the auxiliary chopping mechanism of this food chopper has the following advantages:

[0018] 1. In the initial stage of chopping ingredients, manually rotate the rotating shaft to drive scraper one and scraper two to scrape off large pieces of ingredients attached to the top wall of the bucket lid and the inner wall of the upper part of the mixing bucket. This ensures that the ingredients can be fully chopped by the chopping components in the mixing bucket, so that the ingredients can be chopped to a basically uniform size, effectively improving the chopping effect of the chopper.

[0019] 2. The connecting sleeve is placed outside the bushing, and the upper end of the bushing directly closes the upper opening of the upper through hole, thereby reducing the sealing structure required for bushing installation. It has the advantages of simple structure and convenient installation. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1 As shown, the auxiliary chopping mechanism of this food chopper includes a base 1, a mixing tank 2 fixed on the base 1, and a lid 3 set on the top of the mixing tank 2.

[0029] in,

[0030] like Figure 1 and Figure 2 As shown, a horizontally arranged connecting arm 4 is fixed above the lid 3. One end of the connecting arm 4 is hinged to the base 1, and the lid 3 is opened or closed by swinging the connecting arm 4. In the actual product, the connecting arm 4 is hinged to the base 1 via a horizontally arranged shaft; the other end of the connecting arm 4 is hinged to a hook 5 via a connecting shaft. A hanging rod 6 matching the hook 5 is horizontally fixed on the outer wall of the mixing tank 2, and when the lid 3 is closed, the hook 5 hooks onto the hanging rod 6, positioning the lid 3.

[0031] like Figure 3 and Figure 4As shown, a bushing 7 is vertically fixed between the connecting arm 4 and the bucket lid 3. The upper end of the bushing 7 passes through the connecting arm 4, and the lower end of the bushing 7 extends into the bucket lid 3. The bushing 7 and the mixing bucket 2 are coaxially arranged. A rotating shaft 8 that matches the bushing 7 is vertically inserted into the bushing 7, and the rotating shaft 8 and the bushing 7 form an axial limiting and circumferential rotation relationship. The upper end of the rotating shaft 8 extends out of the bushing 7, and the lower end of the rotating shaft 8 extends into the bucket lid 3 and is fixedly connected to a connecting frame 9. A scraper 10 and a scraper 21 are fixed on the connecting frame 9, and the scraper 10 and the scraper 211 are used to scrape the inner side of the top wall of the bucket lid 3 and the inner side wall of the upper end of the mixing bucket 2, respectively.

[0032] In the initial stage of chopping ingredients, the rotating shaft 8 is manually rotated to drive the scraper 10 and scraper 21 to scrape off large particles of ingredients attached to the top wall of the lid 3 and the inner wall of the upper end of the mixing tank 2. This ensures that the ingredients can be fully chopped by the chopping components in the mixing tank 2, so that the ingredients can be chopped to a basically uniform size, effectively improving the chopping effect of the chopper.

[0033] In this embodiment,

[0034] The connection between the bucket lid 3 and the connecting arm 4 is as follows: The top of the bucket lid 3 has a vertically arranged connecting cylinder 3a, and the connecting cylinder 3a and the bucket lid 3 are coaxially arranged; the bucket lid 3 is fixedly connected to the connecting arm 4 through the connecting cylinder 3a, and a seal is formed between the upper end of the connecting cylinder 3a and the connecting arm 4; the connecting cylinder 3a is sleeved on the bushing 7, and the connecting arm 4 has an upper through hole 4a through which the upper end of the bushing 7 passes, and the upper end of the bushing 7 closes the upper opening of the upper through hole 4a. The connection cylinder 3a sleeves on the bushing 7, and the upper end of the bushing 7 directly closes the upper opening of the upper through hole 4a, thereby reducing the sealing structure required for installing the bushing 7, and has the advantages of simple structure and convenient installation.

[0035] Preferably, the connecting cylinder 3a and the lid 3 are an integral structure; the top wall of the connecting cylinder 3a is in close contact with the connecting arm 4 to form a seal; the connecting cylinder 3a and the connecting arm 4 can be bonded or welded together.

[0036] like Figures 3 to 6 As shown, the bushing 7 is installed as follows: The upper end of the bushing 7 is a ring-shaped limiting seat 7a, which presses against the upper side of the connecting arm 4 and closes the upper opening of the upper through hole 4a.
