Description

Technical Field

[0001] The present invention relates to the field of food processors, and in particular to a connecting rod driven start switch structure and a food processor. Background Art

[0002] The emergence of food processors has provided people with a new way of eating. Through the rapidly rotating sharp blades, food processors can mix fruits, vegetables and other ingredients and mash them into a paste, allowing people to eat several kinds of fruits and vegetables at the same time and increase nutritional intake. However, it is precisely this convenient rotating blade that also brings safety risks to food processor users.

[0003] For example, some food processors on the market require one hand to hold down the switch while the other hand feeds food, which is extremely inconvenient to use. Furthermore, if one accidentally puts one's hand into the barrel when using such products, irreparable damage will occur. In order to solve such problems, someone has invented a food processor structure in which a linkage mechanism triggers a microswitch during food feeding, so that the mixing blade of the food processor works when feeding and stops when the food is stopped, thereby increasing the safety of the food processor. However, most food processors have a longitudinal structure from the feeding area to the mixing area, and their linkage switches are also designed to be slender longitudinal structures, which are prone to displacement. Therefore, the overall structure requirements of the food processor are relatively high, the manufacturing cost is also high, and the food processor is prone to problems during use.

[0004] The above problems are worth solving. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a connecting rod driven start switch structure and a food processor.

[0031] In order to better understand the purpose, technical solution and technical effect of the present invention, the present invention is further explained below in conjunction with the accompanying drawings and embodiments. At the same time, it is stated that the embodiments described below are only used to explain the present invention and are not used to limit the present invention.

[0032] like Figure 1 As shown, a food processor includes a main machine 4, a feeding mechanism 1, a stirring part 5, a power plug 6 and a connecting rod driven start switch structure. The feeding mechanism 1 includes a feeding barrel 11 and a hopper 12. The feeding barrel 11 and the hopper 12 have the same shape, and the feeding barrel 11 is inserted into the hopper 12 and fits. A stirrer is provided in the stirring part 5. A discharge port 51 is provided on one side of the stirring part 5, that is, next to the stirrer. The opening of the discharge port 51 is tilted downward, and the edge of the lower semicircle of the discharge port 51 protrudes outward. After the food processor is used to stir the food, the crushed food is easy to flow out from the tilted and protruding discharge port, and the U-shaped discharge port is also convenient for collection.

[0033] The connecting rod driven start switch structure includes a linkage mechanism 2 and a micro switch 3. The feeding mechanism 1 is connected to the micro switch 3 through the linkage mechanism 2. The linkage mechanism 2 includes a connecting rod 21 and a guide push rod 22. The feeding mechanism 1 is arranged next to the main machine 4. A connecting head 112 is provided on the side of the feeding barrel 11 close to the connecting rod 21. The rod head of the connecting rod 21 is inserted into the socket of the connecting head 112 and is fixedly connected to the feeding barrel 11. The guide push rod 22 and the micro switch 3 are both arranged inside the main machine 4. The stirring part 5 is arranged below the hopper 12, and the internal cavities are communicated.

[0034] like Figure 2 As shown, a connecting rod driven start switch structure, the linkage mechanism 2 includes a connecting rod 21 and a guide push rod 22, the connecting rod 21 is inserted into the main unit 4, the rod tail of the connecting rod 21 is in contact with the guide push rod 22, the other end of the guide push rod 22 is connected to the elastic start key 31 of the micro switch 3, the micro switch 3 is electrically connected to the controller of the food processor, and the controller is connected to the stirrer. A spring 23 is provided on the side of the guide push rod 22 close to the micro switch 3, when the connecting rod 21 moves downward, the guide push rod 22 is pushed to move in the direction of the micro switch 3, the connection line between the micro switch and the guide push rod is perpendicular to the connecting rod, forming a horizontal start structure, the structure is simple and stable, not only reduces the cost of the food processor, but also the food processor starts the feedback quickly, improving the user experience.

[0035] In a specific embodiment, the connecting rod 21 is cylindrical, and a strip groove for placing the connecting rod 21 is provided inside the main body 4, and the connecting rod 21 can slide in the strip groove. The rod tail of the connecting rod 21 is provided with a first inclined surface 211. In this embodiment, the rod tail is conical, and a second inclined surface 221 is provided on the side of the guide push rod 22 close to the connecting rod 21. The second inclined surface 221 extends to the movement trajectory of the connecting rod 21. When the rod tail of the connecting rod 21 and the guide push rod 22 are at the same height, the second inclined surface 221 is in contact with the first inclined surface 211. When the connecting rod 21 moves downward along the strip groove, a force is generated on the first inclined surface 211 and the second inclined surface 221. Due to the limitation of the strip groove, the connecting rod 21 will not be laterally displaced. The force can only force the guide push rod 22 to move in the direction of the micro switch 3 and compress the spring 23; when the connecting rod 21 moves upward to the point where its rod tail is at the same height as the guide push rod 22, the spring 23 on the guide push rod 22 releases its elastic force, pushing the guide push rod 22 to move in the direction of the connecting rod 21. The limiting effect of the strip groove on the connecting rod ensures that the connecting rod is not easily misplaced, making the food processor less prone to errors and reducing maintenance costs.

[0036] In order to better realize the back and forth movement of the guide push rod 22 between the connecting rod 21 and the micro switch 3, in this embodiment, a cylindrical rod 224 is provided on the side of the guide push rod 22 close to the micro switch 3, and a disk 223 is provided in the middle of the guide push rod 22. The cylindrical rod 224 is fixed at the center of the disk 223, and the cylindrical rod 224 is sleeved with a spring 23. One end of the spring 23 is connected to the disk 223, and the other end is connected to the inner wall of the main machine.

[0037] The elastic start key 31 of the micro switch 3 is in contact with the cylindrical rod 224 of the guide push rod 22. When the guide push rod 22 approaches the micro switch 3, the cylindrical rod 224 squeezes the elastic start key 31 to close it, and the micro switch 3 is turned on; when the guide push rod 22 is away from the micro switch 3, the elastic start key 31 returns to the open state due to its own elasticity, and the micro switch 3 is closed.

[0038] like Figure 3 , Figure 4 As shown, when there is no food in the hopper 12, the feeding barrel 11 is at the top of the hopper 12, the rod head of the connecting rod 21 is fixed on the feeding barrel 11, the rod tail of the connecting rod 21 is in a state of just being inserted into the main unit 4, the height of the rod tail is at the same level as the height of the guide push rod 22, the second inclined surface 221 contacts the first inclined surface 211 of the rod tail, the guide push rod 22 is away from the micro switch 3, and the micro switch 3 is not turned on.

[0039] like Figure 5 , Figure 6 As shown, when food is put into the hopper 12, the feeding barrel 11 is pressed to make the feeding barrel 11 go deep into the hopper 12, and the rod head of the connecting rod 21 is fixedly connected to the feeding barrel 11, so the connecting rod 21 moves downward along with the feeding barrel 11, pushing the guide push rod 22 close to the micro switch 3, the micro switch 3 is turned on, and the controller controls the agitator to work, so that the agitator runs when the feeding barrel is pressed into the food, and the agitator stops running when the feeding barrel is pulled out after the mixing is completed. Unlike the traditional food processor, the feeding and the switch are operated separately, and the agitator runs idle, which is easy to cause safety hazards.

[0040] In order to facilitate the insertion and removal of the feeding barrel 11 in the hopper 12, in a specific embodiment, the feeding barrel 11 is consistent with the shape of the hopper 12, the feeding barrel 11 is inserted into the hopper 12, and the feeding barrel 11 fits with the hopper 12, so that the feeding barrel 11 moves smoothly in the hopper 12 without shaking; at the connection between the feeding barrel 11 and the rod head of the connecting rod 21, the feeding barrel 11 is provided with a connecting head 112 with a socket, the connecting rod 21 is inserted into the socket, and the depth of the socket is greater than 2 cm, which serves to increase the connection firmness between the connecting rod 21 and the feeding barrel 11, and an arc-shaped piece 111 is provided between the connecting head 112 and the feeding barrel 11 to fill the gap in the middle. The arc-shaped piece 111 strengthens the stability of the connecting rod 21, and the connecting rod 21 will not be twisted when the feeding barrel 11 is pressed hard.

[0041] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
