In order to solve the problem that the aircraft nose rocks and/or shifts easily in the cooking machine use, the embodiment of this application discloses a cooking machine. Referring to fig. 1, 6, 10, 14, 15 and 16, the food processor includes a cup assembly 20 and a head 10. Fig. 1 and 16 illustrate that the cup assembly 20 includes a cup 202 and a lid 203. The cup 202 includes a cup locking structure, which is a protrusion 2021, as shown. The cover 203 includes a first cover locking structure 2033 and a second cover locking structure spaced circumferentially around the cover 203. The respective structures of the cup body locking structure and the first cover body locking structure are not limited, and the main function is that the two are matched to lock the cover body 203 and the cup body 202 into a whole, for example, the locking structures are realized by blocking, friction positioning or buckling. Further, for the purposes of this application, the locking between the lid 203 and the cup 202 may include two situations: 1) the lid 203 and the cup 202 are relatively fixed, which can be understood as being completely locked; 2) there may be relative movement between the lid 203 and the cup 202 (which may be understood as not being fully locked), but this movement is not sufficient to allow the lid 203 to be removed from the cup 202. Although the figures illustrate the first lid locking structure and the cup locking structure as being plural, the skilled person will understand that the number of the first lid locking structure and the cup locking structure may be one, for example, in the case that the contact area of the first lid locking structure and the cup locking structure is large, the number may be one. The food processor can be a juicer, a cook, a following cup or a meat grinder, so that the cup body assembly 20 is different according to different products, for example, fig. 1 and 16 take the meat grinder as an example, which illustrates that the cup body 202 includes a bowl and the cover body 203 includes a bowl cover. The handpiece 10 includes a handpiece locking structure disposed at the bottom of the handpiece 10 around the circumference of the handpiece 10. The number of the head locking structures and the number of the second cover locking structures are not limited, for example, 2, 3, 4, and the like. Each second cover body locking structure is matched with the corresponding machine head locking structure so that the machine head 10 and the cover body 203 are in a locking state, wherein the machine head 10 is provided with the motor assembly 3, the cup body assembly 20 is provided with the knife assembly 201 driven by the motor assembly 3, or the machine head 10 is provided with the motor assembly 3 and the knife assembly 201 driven by the motor assembly 3. So set up, lid 203 and cup 202 pass through cup locking structure and first lid locking structure locking, and aircraft nose 10 and lid 203 pass through aircraft nose locking structure and the locking of second lid locking structure, and from this, cup, lid and aircraft nose locking are a whole, and in cooking machine working process, aircraft nose or cooking machine are difficult to produce and rock and/or shift, use and experience well, for example can be a full-automatic cooking machine. The wobble ratio is such that the handpiece 10 is wobbled relative to the cover 203 as shown. In addition, cup 202 and lid 203 are through cup locking portion and the locking of first lid locking portion, from this, prevent that the lid from breaking away from the cup at cooking machine working process, improve user experience. Based on the above-mentioned functions of the second cover body locking structure and the handpiece locking structure, the skilled person can understand that the structures of the second cover body locking structure and the handpiece locking structure are not limited, for example, the locking structures are realized by blocking, friction positioning or buckling, etc. Furthermore, for the purposes of the present application, the locking between the head and the cover can include two cases: 1) the cover 203 and the handpiece 10 are relatively fixed, which can be understood as being completely locked; 2) there may be relative movement of the cover 203 and handpiece 10 (which may be understood as not being fully locked), but this movement is not sufficient to allow the handpiece 10 to be removed relative to the cover 203. Although the figures illustrate that there are a plurality of second cover body locking structures and a plurality of head locking structures, the skilled person will understand that the number of the second cover body locking structures and the head locking structures may also be one, for example, in the case that the contact area between the second cover body locking structures and the head locking structures is large, the number may be one.

In one embodiment, the head locking structure and the second cover locking structure are combined to form a snap structure, the head 10 rotates around the cup assembly 20 to enable the head locking structure and the second cover locking structure to be snapped to enable the head and the cover to be in the locked state, and the screwing direction of the head 10 is opposite to the rotating direction of the knife assembly 201. The opposite direction is such that handpiece 10 is rotated counterclockwise and knife assembly 201 is rotated clockwise. So set up, realize through buckle structure aircraft nose 10 with the realization simple structure of cup body component 20 locking, aircraft nose 10's screw in direction with knife tackle spare 201 can make buckle structure detain mutually and be difficult to drop in the opposite direction of rotation at work, has further ensured that the cooking machine is difficult to rock and/or shift at the course of the work. Based on the effect of above-mentioned buckle structure, its concrete structure is not limited, no longer gives details.

Referring to fig. 2 to 3, a specific structure of the second cover locking structure and the head locking structure is described as follows. The handpiece 10 comprises a housing 1 and a bottom cover 14. Each of the head locking structures includes a clamping rib 141 disposed on the bottom cover 14, the bottom of the housing 1 includes a cavity, the bottom cover 14 is located in the cavity and forms an accommodating groove 15 with a side wall of the cavity, and the clamping rib 141 is located in the accommodating groove 15, as shown in fig. 8 and 9.

Referring to fig. 4 and 5, in an embodiment, each of the second cover locking structures includes a buckle 205 disposed on the top of the cover 203, and in a case that the cover 203 includes a handpiece accommodating cavity 2031, the top of the cover 203 is the bottom of the handpiece accommodating cavity 2031. What kind of part of buckle 205 sets up in lid 203 differs according to the kind of cooking machine, for example in fig. 1, the cooking machine is full-automatic meat grinder, therefore, buckle 205 sets up on lid (bowl lid) 203. With the cover 203 and the handpiece 10 assembled, the catch 205 is located within the receiving slot 15, as shown in fig. 8 and 9. So set up, buckle 205 with card muscle 141 is located in the holding tank 15, afterwards, rotate aircraft nose 10 and make card muscle 141 and buckle 205 detain mutually, and the equipment is convenient, and card muscle 141 is difficult to drop with buckle 205. In the above embodiment, the number of the locking ribs 141 and the number of the locking hooks 205 are not limited to 3 as shown in the figure, and may be 2, 4, or the like.

With continued reference to fig. 4 and 5 in conjunction with fig. 8 and 9, each of the second cover locking structures includes a latch 205. In the case where the cover 203 includes the head accommodating cavity 2031, the snaps 205 are provided at the bottom of the head accommodating cavity 2031 at intervals in the circumferential direction of the cover 203. The width of the buckle 205 is gradually increased along the direction that the machine head 10 is screwed into the cup body assembly 20; as shown in fig. 8, the handpiece 10 is screwed into the cup assembly 20 in a counterclockwise direction (the screwing direction is shown by an arrow in fig. 8), and particularly, as shown in fig. 5, the width of the catch 205 is gradually increased in the counterclockwise direction, and the width of the catch 205 is gradually increased from 0 to W1. The skilled person can understand that the variation of the width of the buckle mainly refers to the variation of the width of the portion engaged with the rib 141, for example, in fig. 4 and 5, the buckle 206 includes the buckle 205 (in this case, the buckle 205 can be understood as a slot capable of buckling with the rib 141), the width of the buckle 206 is gradually increased along the screwing direction, and other shapes are also possible, and of course, the buckle 205 may also have other shapes.

Referring to fig. 3 in combination with fig. 8 and 9, each of the head locking structures includes a clamping rib 141 disposed at the bottom of the head 10, the clamping rib 141 is located in the accommodating groove 15, and the width of the clamping rib 141 is gradually reduced along the direction in which the head 10 is screwed into the cup assembly 20. As shown by the arrow in fig. 8, the head 10 is screwed into the cup assembly 20 in the counterclockwise direction, and the width of the rib 141 gradually decreases from W2 to 0mm in the direction of the arrow. So set up, because the width of card muscle 141 is followed aircraft nose 10 screw in the direction of lid 203 reduces gradually, and buckle 205's width is followed aircraft nose 10 screw in cup body assembly 20's direction crescent, like this, the opposite direction of change of both widths makes aircraft nose 10 screw in cup body assembly 20 back, and the great part of buckle 205 width is laminated with the great part of card muscle 141 width, and from this, buckle 205 is firm with card muscle 141 lock, is difficult to drop, and moreover, aircraft nose 10 and cup body assembly 20's assembly is more convenient.

With continued reference to fig. 5 and 3, the maximum width of the buckle 205 is W1, W1 is 3mm ≦ 10mm, such as 3mm, 3.2mm, 3.4mm, 3.5mm, 4mm, 4.3mm, 4.5mm, 4.7mm, 5mm, 5.5mm, 5.8mm, 6mm, 6.5mm, 6.8mm, 7mm, 7.2mm, 7.5mm, 8mm, 8.2mm, 8.5mm, 8.8mm, 9mm, 9.5mm, 9.8mm, or 10mm, in other words, the width of the buckle 205 gradually increases from 0mm to W1 along the screwing direction of the handpiece 10, such as, where W1 is equal to 5, the width of the buckle 205 gradually increases from 0mm to 5mm, and where W1 is equal to 6, the width gradually increases from 0mm to 6 mm. The maximum width of the clamping rib 141 is W2, W2 is more than or equal to 3mm and less than or equal to 10mm, such as 3mm, 3.2mm, 3.4mm, 3.5mm, 4mm, 4.3mm, 4.5mm, 4.7mm, 5mm, 5.5mm, 5.8mm, 6mm, 6.5mm, 6.8mm, 7mm, 7.2mm, 7.5mm, 8mm, 8.2mm, 8.5mm, 8.8mm, 9mm, 9.5mm, 9.8mm or 10 mm. In other words, the rib 141 gradually decreases from W2 to 0 along the direction in which the handpiece 10 is screwed into the cup assembly 20, for example, the width of the rib 141 gradually decreases from 5mm to 0mm in the case where W2 is equal to 5, and gradually decreases from 6mm to 0mm in the case where W2 is equal to 6. So set up, buckle 205 and card muscle 141 lock are firm, are difficult to drop, and moreover, the assembly of aircraft nose 10 and cup body component 20 is more convenient.

Referring to fig. 7 in combination with fig. 6, in the locked state, the width of the abutting surface of the buckle 205 contacting with the clamping rib 141 is W3, and W3 is greater than or equal to 1mm, for example, 1mm, 2mm, 3mm, and the like. So set up buckle 205 with under the circumstances of the equal gradual change of the respective width of card muscle 141, the broad of both contacts of buckle 205 and card muscle 141, and be difficult to drop, rock and/or shift, and then, aircraft nose 10 and cup body assembly 20 are difficult to drop, and the cooking machine is difficult to rock and/or shift at the course of the work.

Referring to fig. 2, 8 and 9, in one embodiment, the handpiece 10 includes a motor assembly 3, a switch assembly 32 connected to a motor of the motor assembly 3, and a link 33, and the handpiece 10 rotates around the cup assembly 20 so that the latch 205 pushes the link 33 to move upward to trigger the switch assembly 32 to be turned on. After the switch assembly 32 is turned on, the motor of the motor assembly 3 can operate to perform the related functions of the food processor. With such an arrangement, the latch 205 pushes the rod 33 to turn on the switch assembly 32, so that the switch assembly 32 is triggered simply, firmly and reliably, and the switch assembly 32 can be triggered reliably.

In one embodiment, the end of the link 33 has an inclined surface that engages the catch 205, the inclined surface being inclined at an angle α, 10 degrees α 60 degrees, with respect to a horizontal plane. For example, 10 degrees, 13 degrees, 15 degrees, 18 degrees, 20 degrees, 22 degrees, 25 degrees, 28 degrees, 30 degrees, 33 degrees, 35 degrees, 36 degrees, 38 degrees, 40 degrees, 45 degrees, 48 degrees, 50 degrees, 52 degrees, 55 degrees, 58 degrees, or 60 degrees. With this arrangement, the angle is within the above range, and the catch 205 is more easily pushed against the link 33 by the guiding action of the inclined surface.

In addition to the manner in which the head locking structure and the second cover locking structure form a snap-fit structure, in some embodiments, the head locking structure and the second cover locking structure attract one another to allow the head and the cover to be in a locked state. So set up, also can make the cooking machine be difficult to rock and/or shift in work. The attraction can be magnetic attraction or negative pressure attraction. The embodiments that utilize magnetic attraction and negative attraction are described in more detail below.
