Abstract

A vacuum food processor comprises a base (1), a blade motor (2), a vacuum pump (3), a cutter head (4), and an ingredient container (7). The ingredient container (7) and the cutter head (4) are sealedly connected to each other to form an ingredient container assembly. A first half coupling (51) is disposed at a motor shaft of the blade motor (2). A second half coupling (52) is disposed at a blade shaft supported by the cutter head (4). The ingredient container assembly and the base (1) are sealed connected to each other to form a coupling cavity (53) respectively communicating with an upper air path and a lower air path. The upper air path communicates with a crushing cavity, and the lower air path communicates with the vacuum pump (3). When in operation, the coupling cavity is configured to be in a vacuum state and at a negative pressure to tightly hold the ingredient container assembly and the base by means of suction, providing simple and reliable sealed communication between the upper and lower air paths and eliminating a fastening device between the ingredient container assembly and the base. In some embodiments, the ingredient container assembly comprises a control valve at the upper air path, and can automatically maintain a vacuum state after producing vacuumed juice, being convenient to store in a fridge as well as taking away to drink. Furthermore, the sealed coupling cavity also functions as a "residue separator" in a vacuuming system.

Technical field

The invention belongs to the technical field of food processor, and particularly relates to a vacuum food pulverizing mixer which is pulverized and/or stirred under the condition of vacuuming.

Background technique

During the pulverization process, the contact between the fine particles and the oxygen in the air is prone to enzymatic browning, resulting in nutrient loss of fruits and vegetables and changes in taste. An effective way to solve the above problems is to isolate the food from air as much as possible during the pulverization process.

The existing vacuum food processing machine comprises a machine base and a material cup body, and a cutter motor, a vacuum pump and a control circuit board are arranged in the machine base; the material cup body is divided into two categories: an inverted material cup and an upper open material cup, and the inverted material is inverted.

Therefore, the present invention has the following advantages over the prior art:

(1) For the cup combination body in which the upper gas path passes through the cutter body and protrudes into the crushing chamber, the suction passage does not need to be attached to the material cup body, which reduces the processing difficulty and cost of the material cup body, and all the air pumping. The components can be arranged on the cutter body. For the inverted cup and the cup with the cup body and the cutter body detachably connected, the cup body does not have any suction parts, so the ordinary inverted cup is used. Or ordinary detachable cups;

(2) Effective use of space, reducing the size of the whole machine;

(3) The coupling chamber is under vacuum negative pressure during working, and the cup body and the base are tightly sucked, so that the cup body can be firmly sucked and placed directly on the base, which can The upper and lower air passages are simply and reliably sealed and connected, and the rotation device between the cup body and the base is omitted, which simplifies the user's operation and is convenient to use;

(4) For the cup combination with the check valve on the upper gas path, after the vacuum juice is prepared, it can be automatically kept in a vacuum state. Therefore, it is very convenient whether you put it in the refrigerator or go out and drink it.

(5) If the food liquid or residue is sucked into the upper airway, the food liquid or residue will first enter the coupling cavity, and the user can conveniently clean the food liquid after opening the coupling cavity. Residue, avoiding the feed liquid sucked in the upper air path directly into the vacuum pump, causing damage to the vacuum pump. The closed coupling cavity also acts as a "soil separator" in the vacuum system.

(6) The level of the lower air passage opening in the coupling cavity is located at a higher position in the coupling cavity. Even if the food liquid or residue is sucked into the airway, the food liquid or residue enters the coupling cavity, because the level of the opening of the lower airway in the coupling cavity is relatively high, so the food liquid is dirty. It is also difficult to get into the vacuum pump.
