Description

Technical Field

[0001] The utility model relates to the technical field of food processors, and in particular to a head-up locking mechanism for a food processor. Background Art

[0002] A food processor is a multifunctional kitchen appliance that can knead dough, beat eggs, and stir, saving time and effort. To facilitate the removal and installation of the dough bucket, the head of the food processor can be tilted upward. A locking mechanism locks the head until it reaches a specific angle and then secures it. After removing and placing ingredients and the dough bucket, the head can be returned to its original position.

[0003] Existing locking mechanisms for food processors use a rotating handle to drive a rotating shaft. For example, CN202110564941.8 discloses a food processor. The locking mechanism in this food processor includes a stop pin, a handle, and a stop plate. The handle is fixed to the end of the stop pin. The stop pin is rotatably connected to the base assembly, and the stop plate is fixedly connected to the head assembly. The stop plate has an arc-shaped hole, with fixing holes at each end of the arc hole. The fixing holes have a larger diameter than the arc hole. The stop pin has a groove to form a neck that penetrates the arc hole, and the stop pin can move along the arc hole to the fixing holes at both ends. When the locking mechanism is in use, the handle is rotated to rotate the stop pin, causing the groove to align with the arc hole, and the neck slides along the arc hole to unlock. The handle is then rotated to align the groove with the arc hole, locking the stop pin in the fixing hole. This locking mechanism requires rotating the handle to drive the stop pin to move together to lock and unlock, which requires considerable force to rotate and is relatively laborious. Utility Model Content

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0025] See also Figure 1-6This embodiment discloses a head locking mechanism for a food processor, used to control the movable rotation or locking between the head and base of the food processor. The locking mechanism includes a guide plate 1 and a locking assembly 2. The guide plate 1 defines a slide 11 with locking holes 12 at both ends. The diameter of the locking holes 12 is larger than the width of the slide 11. The locking assembly 2 includes a locking shaft 21 and a button seat 22. The locking shaft 21 passes through the locking holes 12 and is assembled with the guide plate 1. The locking shaft 21 has a groove 211 and the rest of the locking portion is a locking portion. The diameter of the locking portion is larger than the width of the slide 11, meaning that the locking portion cannot pass through the slide 11. A spring 23 is sleeved on one end of the locking shaft 21 and fixedly connected to the button seat 22. The spring 23 is located between the guide plate 1 and the button seat 22 and abuts against the button seat 22. When the locking mechanism is installed on the chef machine housing 100, the button seat 22 is located outside the housing 100, which is convenient for user operation. In this embodiment, two guide rails 2 are provided.

[0026] The locking mechanism of this embodiment is constructed by sleeved spring 23 on locking shaft 21. Locking shaft 21 is fixed to button seat 22. Spring 23 can abut button seat 22. Pressing button seat 22 drives locking shaft 21 inward, causing groove 211 to locate within locking hole 12. The food processor head and base are unlocked. Locking shaft 21 slides from one end of slideway 11 to the other. When it enters locking hole 12 at the other end, the restoring force of spring 23 presses button seat 22 outward, causing locking shaft 21 to move outward. The locking portion is located within locking hole 12, and the food processor head and base are locked. The locking mechanism of this embodiment can be unlocked by simply pressing button seat 22. The user automatically locks the food processor head and base after raising the head to a preset angle or closing the head, making operation more labor-saving and convenient.

[0027] See also Figure 4 and Figure 5 The button seat 22 is provided with a shaft seat 221, which is provided with an axial hole 2211. The locking shaft 21 is clamped in the axial hole 2211, and one end of the spring 23 is sleeved on the outer wall of the shaft seat 221. In this embodiment, the button seat 22 has an inner cavity, and the shaft seat 221 is located in the middle of the inner cavity. The cavity formed between the shaft seat 221 and the outer wall of the button seat 22 can accommodate the spring 23, so that when the user presses the button seat 22, the spring 23 can be better squeezed, generating a greater restoring force to reset the locking seat 21.

[0028] Furthermore, a plurality of buckles 2212 are provided on the outer wall of the shaft seat 221 , and one end of the spring 23 is clamped on the buckle 2212 , so that the spring 23 is more firmly clamped in the button seat 22 .

[0029] See also Figure 4 and Figure 5 In order to prevent the locking shaft 21 and the button seat 22 from slipping, a first plane is provided at one end of the locking shaft 21, and a second plane 2214 is provided at the rotating shaft seat 221, and the first plane is adapted to the second plane.

[0030] Furthermore, through holes 2213 are symmetrically provided on the outer wall of the rotating shaft seat 221 , and the fasteners 25 pass through the through holes 2213 to fix the locking shaft 21 to the rotating shaft seat 221 .

[0031] Furthermore, the button seat 22 is provided with a notch 222 , the position of the notch 222 corresponds to the through hole 2213 , and the fastener 22 can pass through the notch 222 and the through hole 2213 in sequence to fix the locking shaft 21 , making the installation of the locking assembly 2 more convenient.

[0032] See also Figure 1-4 A limiting member 24 is provided at one end of the locking shaft 21 away from the button seat 22 to prevent the locking shaft 21 from escaping from the locking hole 12 .

[0033] Furthermore, the stopper 24 includes an elastic stopper 241 and a pin 242. The elastic stopper 241 is sleeved on the locking shaft 21, and the pin 242 is detachably mounted on the locking shaft 21. The pin 242 is located on one side of the elastic stopper 241 near the end of the locking shaft 21, limiting the position of the elastic stopper 241. The use of the elastic stopper 241 in this embodiment can prevent wear caused by the rigid contact between the elastic stopper 241 and the guide rail plate 1 when the spring 23 utilizes the restoring force to lock the stopper 241 when excessive pressure is applied. In this embodiment, the pin 242 is an R-shaped cotter pin.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0035] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
