Description

Juicer with lateral molars in the cutter disc

Field of the Invention This invention relates to household machinery for comminuting or mashing food products, and more particularly to citrus fruit presses, other fruit juice extractors and vegetable juice presses. Background technique

Prior art juicers include a base, a juice extraction chamber disposed above the base, and an upper cover overlying the juice extraction chamber. A motor is disposed in the base, and an output shaft of the motor is coupled to a cutter disc disposed in the juice extraction chamber by a coupling. The prior art juicer generally extracts juice from fruits, vegetables, and the like as feed materials in a juice extraction chamber, and separates the residue from the juice. A feeding tube is disposed above the juicing chamber to feed the juiced food to the juicing chamber. The cutter disc disposed in the juice extraction chamber is arranged in a plane and horizontally, and an inverted frustoconical filter screen that rotates with the cutter disc is arranged around the cutter disc, and is driven by a motor at a high speed, on the cutter head The wiping teeth complete the scraping and pulverizing of the juiced food to produce the slag and the fruit and vegetable juice; the slag is pulled upward and outward through the centrifugal action of the inclined surface of the filter screen, beyond the edge of the filter screen, and falls into the slag receiving In the device, the juice is passed through a sieve into another collector.

However, the above prior art juicers have drawbacks and deficiencies:

The cutters on the existing market are mostly round flat cutters. The cutters are provided with wiping teeth, and the juiced food is scraped by rotating teeth to become small pieces of food. Some of the food pieces are collected directly into the slag receiver as a slag by the centrifugal force and through the gap between the feed tube and the cutter head. The juice of this small portion of the food is not fully scratched and is pulled out of the juice chamber, which affects the juice yield of the juicer. Summary of the invention

The technical problem to be solved by the present invention is to avoid the deficiencies of the prior art and to provide a juicer with a side-toothed cutter on the cutter head, so that the small pieces of food pass through the gap between the feed tube and the cutter head, After continuing to scrape, it enters the slag receiver, so that the food pieces are fully scraped before being pulled out of the juice extraction chamber, which improves the juice extraction rate of the juicer.

The technical problem solved by the present invention can be achieved by using the following technical solutions:

Designing and manufacturing a juicer having a laterally toothed cutter, comprising a base, a juice extraction chamber above the base and an upper cover covering the juice extraction chamber, the motor being fixed inside the base, the motor The output shaft is coupled to the cutter head and the screen in the juice extraction chamber. In particular, the cutter head includes a horizontal chassis and side edges, and the horizontal chassis and the side edges are machined with the wiping teeth. Specifically, the horizontal chassis is circular, and the side edges are inverted frustoconical shapes.

Confirmation In order to ensure that the food pieces are sufficiently scratched on the teeth on the side edges of the cutter head, the angle between the side of the cutter head and the chassis is between 110 and 160 degrees.

Further improving the above technical solution, the upper cover is provided with a feeding pipe, and a gap is left between the lower end surface of the feeding pipe and the chassis of the cutter head to form a juice cutting space. Compared with the prior art, the invention has the beneficial effects that the "cutter has a side-squeezing juicer":

1. The juiced food as the feed is scraped into a small piece of food by rotating the teeth on the horizontal chassis of the cutter head, after the food piece passes through the gap between the feed tube and the cutter head The food pieces are further scraped by the rubbing teeth on the side of the cutter head before entering the slag receiver, so that the juiced food is sufficiently scratched, thereby increasing the juice yield of the juicer;

2. The brushing area of the juicer of the juicer of the invention is increased, and the large-diameter fruit and vegetable can be scraped, the utility scope is wide, and the utility is enhanced;

3. The juicer has a simple structure and convenient replacement of various components, which is suitable for large-scale production of series products and reduces production costs. DRAWINGS

The following further description is made in conjunction with the preferred embodiments shown in the drawings.

In the present invention, the "cutter is provided with a laterally-squeezing juicer", as shown in FIGS. 1 to 4, includes a base 1, and the base 1 is provided with a switch 2, and the base 1 is provided with a motor 3 and an electric press. Juice chamber 91. A cutter disc 4 is disposed in the juicing chamber 91, and an inverted truncated cone-shaped screen 5 is disposed around the cutter disc 4. In a preferred embodiment of the invention, the juice extraction chamber 91 is surrounded by a barrel-shaped juice extraction tube 9. The cutter head 4 and the screen 5 are coupled to the output end of the motor 3 via the coupling 32, i.e., the output shaft 31 of the motor 3. The base 1 is provided with an upper cover 6.6, and the upper cover 6 is vertically provided with a straight tubular feed tube 7, or a feed cylinder 7, and the feed tube 7 is provided with a push rod 8 . A gap is formed between the lower end surface of the feed pipe 7 and the cutter head 4 to form a juice cutting space 92.

In a preferred embodiment of the present invention, as shown in FIG. 4, the cutter head 4 is of a unitary design and has a round bowl shape including a horizontal chassis 41 and side edges 42. The horizontal chassis 41· is circular, and the side 42 is an inverted frustoconical shape. At the circular level Wiping teeth 43 are formed on both the chassis 41 and the side edges 42. Of course, the cutter head 4 can also adopt a split design, that is, the bottom plate 41 and the side edge 42 are divided into two parts, and the side 42 portion is designed with an inverted frustoconical shape, and the wiper teeth are separately provided. When in use, it can be fixed to the filter. In a preferred embodiment of the invention, the angle between the secluded edge 42 of the cutter head 4 and the horizontal chassis 41 is 135 degrees. In order to ensure that the food pieces are sufficiently scraped on the teeth on the side of the cutter head, the angle between the side 42 of the cutter head 4 and the horizontal chassis 41 can be 110-160 degrees in product design. Choose between. The shape and arrangement of the wiping teeth 43 can be various. In a preferred embodiment of the present invention, the wiping teeth 43 are disposed along the radial direction of the cutter head 4.

In a preferred embodiment of the invention, the juiced fruit or vegetable is fed from the dither tube 7 to the juicing chamber 91, onto the upper surface of the chassis 41 of the cutter head 4, the switch 2 is turned on, and the output shaft 31 of the motor 3 is turned on. The cutter disc 4 and the screen 5 are driven to rotate at a high speed by means of a coupling 32, and the wiper teeth 43 on the cutter head 4 will scrape and smash the juiced food. Since the juiced food is affected by the rotational force of the cutter head 4, it will continuously jump upward, so the pusher rod 8 can be used against the juiced food to enhance the crushing effect. After the juiced food is pulverized to a certain extent, the small pieces will pass through the gap between the lower end surface of the feed pipe 7 and the horizontal pan 41 of the cutterhead, and are moved upward and downward along the slope of the filter screen by centrifugal force. Out of the box, enter the slag receiver. Since the cutter head 5 has a round bowl shape, the side edges 42 are also provided with the wiping teeth 43, so that the small pieces are passed through the gap between the lower end surface of the feed tube 7 and the cutter head 4, and are on the side edges 42. The wiper is again scraped and shredded, into smaller pieces, into the slag receiver. Thus, the juice extraction rate of the juicer is greatly improved.
