Description

Technical Field

[0001] The invention belongs to the technical field of kitchen appliances and relates to a multifunctional food processor. Background Art

[0002] In kitchen cooking, stirring is a common step, such as beating eggs, washing rice, and cleaning fruits and vegetables. However, traditional stirring methods rely heavily on manpower, which causes wrist soreness and the risk of incomplete cleaning or damage to ingredients due to uneven stirring force.

[0003] In the prior art, different tools are designed for stirring different ingredients, for example, egg beaters are designed for beating eggs, double-layer drain baskets are designed for washing fruits and vegetables, and rice washing cups are designed for washing rice. The drain baskets and rice washing cups not only rely on the impact of water flow to clean the ingredients, but also require manual assistance in stirring or shaking the utensils during the cleaning process. Therefore, manual cooking tools have the problem of poor convenience in use. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a multifunctional food processor to solve the technical problems that the existing food processors are inconvenient to use and have low manual stirring efficiency.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A multifunctional food processor comprises a basin body and a stirring piece, the outer wall of the basin body is provided with a handle, and the characterised in that the stirring piece is detachably connected to the basin body, the multifunctional food processor also comprises a connecting rod and a gear set, the gear set is provided at the bottom of the basin body and can drive the stirring piece to rotate, the handle is provided with a trigger, the connecting rod is rotatably connected to the handle, and one end of the connecting rod is hinged to the trigger, the outer wall of the basin body is provided with a push rod that can slide vertically, and the upper end of the push rod at the other end of the connecting rod is hinged, the gear set comprises a sector gear for power input, and the lower end of the push rod has a wedge surface that can act on one side of the sector gear. After pulling the trigger, the connecting rod drives the push rod to slide vertically, so that the wedge surface drives the sector gear to swing, and then the gear set rotates to drive the stirring piece to rotate.

[0007] The present application is to stir the food with the help of a stirring piece. When in use, the food to be stirred is put into the basin body, the handle is held and the trigger is pulled, the stirring piece rotates, and the food is stirred in the basin body. The power transmission structure from the trigger to the stirring piece is explained: a connecting rod is rotatably connected in the handle, the trigger is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the push rod. After the trigger is pulled, the trigger drives the connecting rod to swing, and the connecting rod drives the push rod to slide vertically, and then the wedge surface drives the gear set to rotate, providing driving force for the gear set. The gear set amplifies the force applied to the trigger through the transmission ratio, drives the stirring piece to rotate quickly, improves the stirring efficiency of the stirring piece, and makes this multifunctional food processor easy to use; the stirring piece is detachably connected to the basin body, so that the stirring piece can be replaced according to different food ingredients, thereby increasing the types of food ingredients that can be processed by this food processor.

[0008] In the aforementioned multifunctional blender, the gear assembly includes cylindrical gear (1), a sector gear rotatably connected to the bottom of the bowl, and a toothed segment at the front end of the sector gear that meshes with cylindrical gear (1). The rear end of the sector gear includes a drive handle with an elliptical cross-section. The push rod is located on one side of the sector gear, with its wedge surface abutting the drive handle. When the push rod slides vertically, the drive handle moves along the wedge surface, causing the sector gear to oscillate, which in turn drives cylindrical gear (1) to rotate. This structure changes the direction of force transmission, converting the push rod's linear motion into rotational motion and increasing the rotational speed of cylindrical gear (1), thereby improving blending efficiency.

[0009] In the aforementioned multifunctional food processor, the connecting rod includes a pin and two swing arms. One end of each swing arm is hinged to either side of the trigger, and the other end of each swing arm is fixedly connected via a pin. The pin is hinged to the push rod. Hinging the two swing arms to either side of the trigger allows the connecting rod to be supported by the trigger, thereby increasing the structural strength of the connecting rod and the rotational stability of the swing arms. The pin enables the two swing arms to rotate synchronously, and hingedly connecting the pin to the push rod increases the contact area between the two, improving the push rod's movement stability, preventing jamming, and ensuring smooth power transmission.

[0010] In the aforementioned multifunctional food processor, the swing arm has a first rotating shaft hinged to the handle on the side away from the trigger, and a second rotating shaft hinged to the swing arm on both sides of the trigger. The distance between the axis of the second rotating shaft and the axis of the first rotating shaft is greater than the distance between the axis of the pin and the axis of the first rotating shaft. This structure incorporates a lever structure, with the first rotating shaft being understood as the fulcrum for the swing arm's rotation, the distance between the axis of the first rotating shaft and the second rotating shaft being the power arm, and the distance between the axis of the first rotating shaft and the axis of the pin being the resistance arm. By setting the length of the power arm greater than the length of the resistance arm, the force required to pull the trigger is reduced, thereby achieving labor-saving effects.

[0011] In the aforementioned multifunctional food processor, the trigger is elongated, one end of which is hinged to the handle. A compression spring is disposed within the handle, elastically acting on the other end of the trigger. The second rotating shaft, located near the trigger, abuts against the end of the compression spring. An elongated hole is defined at one end of the swing arm, extending along its length. The second rotating shaft passes through the hole and is movable along the hole. The trigger's hinge point is located at one end, allowing the compression spring to act on the other end of the trigger, thereby increasing the trigger's rotation angle. The elongated hole increases the swing range of the swing arm, thereby increasing the swing range of the sector gear, thereby further improving the blending efficiency of the food processor.

[0012] In the aforementioned multifunctional food processor, a vertically disposed guide rail is provided on the outer wall of the basin. The push rod comprises a push section and a rod-shaped transmission section. The width of the transmission section is smaller than the width of the guide rail. The transmission section is hingedly connected to a pin, and the push section slides with the guide rail. The side of the push section abutting the guide rail has the aforementioned wedge surface. Making the transmission section smaller than the width of the guide rail reduces friction between the push rod and the guide rail, while also increasing the freedom of movement of the push rod's upper end, potentially preventing jamming during power transmission. The sliding engagement of the push section with the guide rail ensures the stability of the movement of the push rod's lower end, and thus the stability of the wedge surface's driving sector gear.

[0013] In the aforementioned multifunctional food processor, the handle comprises an upper cover and a grip. The upper cover is positioned above the grip and the two are connected by a snap-fit connection. The connecting rod is rotatably connected between the grip and the upper cover. The trigger is located on the grip, and the compression spring is located between the trigger and the upper cover. Separating the handle into the upper cover and grip facilitates assembly and maintenance of the connecting rod. Positioning the trigger on the grip is ergonomic, preventing accidental activation while facilitating hand exertion.

[0014] In the multifunctional food processor described above, stoppers are provided on both sides of the trigger, and a clearance opening is defined in the handle. Under the elastic force of the compression spring, the trigger extends through the clearance opening, causing the stoppers to abut against the inner wall of the handle. The clearance opening makes the trigger easily accessible, and the stoppers determine the distance the trigger extends through the clearance opening under the elastic force of the compression spring.

[0015] In the aforementioned multifunctional food processor, the handle further includes a base, which engages with the bottom of the basin to form a receiving cavity, within which the gear train is located. The handle further includes a vertically disposed connecting portion that abuts against the outer wall of the basin. The connecting portion connects the handle and the base, and the three are internally interconnected. The guide rail is located between the connecting portion and the outer wall of the basin, allowing the push rod to extend into the receiving cavity. The base supports the bottom of the basin, protecting the gear train, and provides clearance for the vertical sliding of the push rod. The connecting portion protects the guide rail, thereby improving the stability of power transmission.

[0016] In the aforementioned multifunctional food processor, a tension spring is installed within the receiving chamber, connecting the base and the fan-shaped gear. The gear train also includes a transmission shaft extending vertically through the bottom of the bowl. One end of the transmission shaft is fitted with a cylindrical gear 2, which is in transmission connection with the fan-shaped gear. The other end of the transmission shaft is detachably connected to the stirring element. The tension spring causes the fan-shaped gear to swing, then return to its initial position under the spring's force. Cylindrical gear 2 transmits power through the transmission shaft, driving the stirring element to rotate.

[0017] Compared with the prior art, the multifunctional food processor provided by the present invention has the following advantages: when using the multifunctional food processor of the present application, one only needs to put the ingredients to be cooked into the basin, hold the handle and pull the trigger to rotate the stirring element in the basin to stir the ingredients in the basin. By replacing the stirring element, different ingredients can be stirred, so that the food processor can cook a variety of ingredients, and the stirring is labor-saving and efficient.
