Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, specifically to a knife recognition structure for a food processor and the food processor itself. Background Technology

[0002] Food processors, as a type of small kitchen appliance, are widely used for tasks such as food mixing, egg beating, and dough kneading. Their ease of use and convenience have made them increasingly popular. However, in practice, users often start the machine with the wrong blades or without any blades installed, leading to cooking failures. Currently available food processors rely solely on users remembering the blade installation steps and cannot detect whether blades are installed in the pot. This makes it easy for users to forget the blades after adding ingredients, resulting in cooking failures and impacting the user experience. Utility Model Content

[0003] This utility model discloses a knife recognition structure for a food processor, comprising: a metal pot body arranged on the food processor, a working knife adapted to the metal pot body, and a signal receiving circuit board installed inside the food processor. The working knife is detachably connected to a drive seat at the bottom of the metal pot body and can rotate inside the pot body under the action of the drive seat. A magnetic sensor is installed at the bottom of the metal pot body, and a magnetic body is installed on the working knife. After the working knife is installed on the adapted metal pot body, the magnetic body can drive the magnetic sensor to send a response signal to the signal receiving circuit board.

[0004] Preferably, the blade recognition structure for the food processor includes a plurality of working blades adapted to the metal pot body, each of which can be detachably connected to a drive seat at the bottom of the metal pot body.

[0005] Preferably, the magnetic sensor does not send a response signal to the signal receiving circuit board after the working knife without a magnet is installed on the metal pot.

[0006] Preferably, the cutting tool includes a rotating shaft and cooking blades arranged around the rotating shaft, and the magnet is mounted on the rotating shaft; the drive seat is provided with an installation channel for the end of the rotating shaft to be inserted and connected.

[0007] Preferably, the bottom of the pot body is made of stainless steel.

[0008] Preferably, the magnetic sensor is installed on the bottom outer side of the pot body, and the magnetic sensor can sense the magnetic body on the working knife installed on the drive seat through the bottom of the metal pot body.

[0009] Preferably, the magnetic sensor includes a sensor housing and two parallel, non-contact elastic iron plates installed inside the sensor housing. The sensor housing includes an upper iron plate and a lower iron plate, which are respectively connected to the two input terminals of a signal receiving circuit board via wires. One end of one elastic iron plate is connected to the upper iron plate, and one end of the other elastic iron plate is connected to the lower iron plate. After the magnetic body is installed on the matching metal pot body by the working tool, the two elastic iron plates can reduce the distance between them due to the magnetic influence.

[0010] This utility model also discloses a food processor, including a food processor body and a knife recognition structure for the food processor as described above, wherein the metal pot body is connected to the food processor body and the signal receiving circuit board is installed in the food processor body.

[0011] This utility model discloses a knife recognition structure for a food processor and the food processor itself. It utilizes a metal pot body with a magnetic sensor installed at the bottom. A magnetic element is attached to the corresponding cutting knife. When the magnetic element is installed on the pot body along with the cutting knife, it drives the magnetic sensor to send a response signal to a signal receiving circuit board. Therefore, when the signal receiving circuit board receives the signal from the magnetic sensor, it indicates that the corresponding knife is installed in the pot. If no signal is received, it indicates that the corresponding knife is not installed in the pot. This prevents cooking failures caused by the user forgetting the knife after adding ingredients, thus avoiding a negative impact on the user experience.

[0012] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of a knife recognition structure for a food processor, as disclosed in an embodiment of the present invention.

[0014] Figure 2 This is a schematic diagram of the structure of a magnetic sensor disclosed in one embodiment of the present invention. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] As attached Figure 1 As shown, this embodiment discloses a knife recognition structure for a food processor, specifically including: a metal pot body 1 arranged on the food processor, a working knife 2 adapted to the metal pot body, and a signal receiving circuit board installed inside the food processor. The working knife is detachably connected to a drive seat 3 at the bottom of the metal pot body and can rotate within the pot body under the action of the drive seat 3. A magnetic sensor 4 is installed at the bottom of the metal pot body 1, and a magnetic body 21 is installed on the working knife 2. When the working knife is installed on the adapted metal pot body 1, the magnetic body 21 can drive the magnetic sensor 4 to send a response signal to the signal receiving circuit board. When a working knife without a magnetic body is installed on the metal pot body, the magnetic sensor does not send a response signal to the signal receiving circuit board. Thus, by using a metal pot body, installing a magnetic sensor at the bottom of the metal pot body, and installing a magnetic body on the adapted working knife, when the magnetic body is installed on the adapted metal pot body along with the working knife, it can drive the magnetic sensor to send a response signal to the signal receiving circuit board. Therefore, when the signal receiving circuit board receives a signal from the magnetic sensor, it indicates that the corresponding knife is installed in the pot. If no signal is received from the magnetic sensor, it indicates that the corresponding knife is not installed in the pot. This avoids the cooking task failing due to the user forgetting the knife after putting in the food, thus affecting the user experience.

[0017] In this embodiment, as shown in the appendix Figure 2As shown, the magnetic sensor 4 is installed on the outer bottom of the pot body. The magnetic sensor can sense the magnetic body on the working knife mounted on the drive seat through the bottom of the metal pot body. The magnetic sensor 4 includes a sensor housing and two parallel, non-contact elastic iron plates 42 and 43 installed within the sensor housing. The sensor housing includes an upper iron plate 411 and a lower iron plate 412, which are respectively connected to the two input terminals of a signal receiving circuit board via wires 44 and 45. One end of one elastic iron plate 42 is connected to the upper iron plate 411, and one end of the other elastic iron plate 43 is connected to the lower iron plate 412. After the magnetic body is installed on the corresponding metal pot body, the two elastic iron plates can reduce their distance due to magnetic influence. In a specific embodiment, if knife identification is required, one knife is equipped with a magnet, and the other knife is not. If the installed knife has a magnet, the iron pot and the iron plate on the magnetic sensor will have magnetic attraction due to the magnetic permeability effect. This magnetic attraction will cause the two elastic iron plates to attract each other, thus reducing the resistance between the two wires. The resistance is measured by the resistance measuring circuit of the signal receiving circuit board to identify the knife. To identify whether a knife is installed, each knife is fitted with a magnet, and the same principle is used for identification. If the resistance decreases, it indicates that a working knife is installed; if the resistance does not decrease, it indicates that no working knife is installed.

[0018] In this embodiment, the blade recognition structure for the food processor further includes multiple working blades adapted to the metal pot body, each of which can be detachably connected to the drive base 3 at the bottom of the metal pot body. Each working blade 2 includes a rotating shaft 22 and cooking blades 23 arranged circumferentially around the rotating shaft, with a magnet 21 mounted on the rotating shaft 22. The drive base 3 has an installation channel for inserting and connecting the end of the rotating shaft 22. In a preferred embodiment, the bottom of the pot body 1 can be made of stainless steel.

[0019] In another embodiment, a food processor is also disclosed, comprising a food processor body and a knife recognition structure as disclosed in the foregoing embodiments, wherein a metal pot is connected to the food processor body, and a signal receiving circuit board is installed inside the food processor body. This allows the food processor to distinguish whether a knife is installed in the pot, preventing cooking tasks from failing due to the user forgetting the knife after adding ingredients, thus affecting the user experience.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
