Description

Technical Field

[0001] The utility model relates to the technical field of small kitchen appliances, in particular to a stirring head. Background Art

[0002] In the field of small kitchen appliances, particularly in the areas of tool design and food mixing, the design and optimization of mixing heads is an important research area. The main function of a mixing head is to cut food into small pieces during rotation for further processing or consumption. Traditional mixing heads typically consist of a fixed blade and a tube housing. The blade is mounted at the bottom of the tube housing and cuts the food through high-speed rotation.

[0003] In the existing technology, the distance between the blade of the stirring head and the bottom of the tube cover is usually fixed. This design works better when processing smaller foods, because the blade can easily contact the food and cut it into small pieces. However, when encountering larger ingredients, there is no way for the large pieces of food to pass through, causing the blade to get stuck. In order to solve this problem, some manufacturers have designed stirring heads with adjustable distances between the blade and the bottom of the tube cover to better handle larger foods. For example, in the patent document with publication number CN107787197A, a processing device for stirring or crushing food is disclosed. This technical solution automatically adjusts the distance between the blade and the bottom of the tube cover by setting a spring. However, this technical solution cannot be manually intervened and can only be automatically adjusted by the spring. In some scenarios where human intervention is required (such as when the blade is stuck), it cannot meet the use requirements of human intervention, which leads to reduced cutting efficiency. Utility Model Content

[0004] The utility model provides a mixing head, which aims to solve the technical problem that the existing mixing head cannot automatically adjust the blade height position and requires manual intervention, resulting in reduced cutting efficiency. The technical solution adopted by the utility model is as follows:

[0005] A stirring head, comprising:

[0006] a stirring body, formed with a sliding groove and a sliding cavity communicating with the sliding groove;

[0007] a knife shaft assembly slidably disposed in the sliding groove, the knife shaft assembly having a first end and a second end disposed opposite to each other, and when a force is applied to the first end or the second end, the knife shaft assembly moves along the sliding groove;

[0008] A pressing assembly is slidably disposed in the sliding cavity and connected to the first end of the knife shaft assembly;

[0009] The elastic member is arranged in the sliding cavity and abuts between the stirring body and the pressing component.

[0010] Furthermore, the stirring body includes an inner lining, the sliding cavity is formed on the inner lining, and the elastic member abuts between the inner lining and the pressing assembly.

[0011] Furthermore, the pressing assembly includes a movable cover and an upper pad, the movable cover and the upper pad are connected, the stirring body also includes a stirring cover and a connecting pipe, the lining is installed in the stirring cover, the connecting pipe is arranged in the stirring cover and connected to the lining, and the sliding groove is formed on the connecting pipe.

[0012] Furthermore, the stirring body further includes a sealing ring, which is arranged close to the second end and abuts between the stirring cover and the connecting pipe.

[0013] Furthermore, the stirring body further includes a bottom plate and a steel plate, the bottom plate is connected to the connecting pipe, and the steel plate is connected to one end of the steel plate facing away from the connecting pipe.

[0014] Furthermore, the stirring body includes a linear bearing, which is arranged in the sliding groove and nested on the knife shaft assembly.

[0015] Furthermore, the stirring body further includes a shockproof block, which is arranged between the linear bearing and the sliding groove, and the shockproof block is made of elastic material.

[0016] Furthermore, the knife shaft assembly includes a rotating shaft and a blade group connected to the rotating shaft, and the blade group is arranged at the second end.

[0017] Furthermore, the blade set includes a first blade and a second blade, the first blade is extended gradually close to the pressing assembly along the radial direction of the rotating shaft, and the second blade is extended gradually away from the pressing assembly along the radial direction of the rotating shaft.

[0018] Furthermore, the knife shaft assembly slides within the range of [0,8] mm.

[0019] Beneficial effects: Compared with the prior art, the stirring head provided by the present invention is provided with a pressing assembly and an elastic member that cooperate with the knife shaft assembly. Under normal circumstances, when cutting food, the blade rotates around the axis. If the blade encounters a large piece of food, the blade will automatically move downward to increase the distance between the blade and the tube cover, allowing large pieces of food to pass through easily. After the large piece of food passes, it will automatically return to its original position due to the spring tension. In cases where human intervention is required, for example, a large piece of food gets stuck in the blade, causing the blade to be unable to work, a pressure is applied above the pressing assembly to increase the distance between the blade and the tube cover. When the blade is close to the front edge of the tube cover, the blade can contact the food faster. Repeatedly applying pressure to the pressing assembly can improve the food cutting efficiency and make the user more flexible when using it. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please refer to Figures 1-4 An embodiment of the present invention provides a stirring head 100, comprising a stirring body 110, a blade shaft assembly 120, a pressing assembly 130 and an elastic member 140. The stirring body 110 is formed with a sliding groove 1131 and a sliding cavity 1111 connected to the sliding groove 1131. The blade shaft assembly 120 is slidably disposed in the sliding groove 1131, and the blade shaft assembly 120 has a first end 121 and a second end 122 disposed opposite to each other. The pressing assembly 130 is slidably disposed in the sliding cavity 1111 and is connected to the first end 121 of the blade shaft assembly 120. The elastic member 140 is disposed in the sliding cavity 1111 and abuts between the stirring body 110 and the pressing assembly 130; when the first end 121 or the second end 122 is subjected to force, the blade shaft assembly 120 moves along the sliding groove 1131. Exemplarily, the elastic member 140 is a compression spring, and the elastic member 140 is disposed near the first end 121. In the initial state, the elastic member 140 is not under any force, and the distance between the blade and the bottom surface 119 of the tube cover is small. When the blade contacts a large piece of food, the large piece of food presses the blade away from the bottom surface 119 of the tube cover, and the spring is compressed. After the large piece of food passes through or is chopped, the blade returns to its initial position under the action of the spring. Alternatively, when the user applies pressure to the pressing assembly 130, the spring is compressed, and the blade position changes. When the user's pressing force disappears, the blade returns to its initial position under the action of the spring.

[0030] Please refer to Figure 1 、 Figure 2 、 Figure 3The mixing head 100 of the present application adopts a sliding groove 1131 plus a spring. By moving the pressing component 130 and driving the knife shaft component 120, the distance between the blade and the bottom of the tube cover can be adjusted quickly and conveniently, so as to quickly switch to process foods of different sizes. During use, the user can adjust the distance between the blade and the bottom of the tube cover by pressing the component 130 according to the size of the food to avoid problems such as knife jamming or low cutting efficiency. In addition, since the blade is designed to be curved, it can fully contact the food, thereby improving cutting efficiency.

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 3 Compared with the prior art, the mixing head 100 provided in the present application is provided with a pressing assembly 130 and an elastic member 140 that cooperate with the blade shaft assembly 120. Under normal circumstances, when cutting food, the blade rotates around the axis. If the blade encounters a large piece of food, the blade will automatically move downward to increase the distance between the blade and the bottom surface 119 of the tube cover, allowing the large piece of food to pass through easily. After the large piece of food passes, it will automatically return to its initial position due to the spring tension. In cases where human intervention is required, for example, a large piece of food gets stuck in the blade, causing the blade to be unable to work, a pressure is applied above the pressing assembly 130 to increase the distance between the blade and the tube cover. When the blade is close to the front edge of the tube cover, the blade can contact the food faster. Repeatedly applying pressure to the pressing assembly 130 can improve the food cutting efficiency and make the user more flexible when using it.

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 In one possible embodiment, the pressing assembly 130 includes a movable cover 131 and an upper liner 132. The stirring body 110 includes an inner liner 111. The movable cover 131 and the upper liner 132 are connected. A sliding cavity 1111 is formed in the inner liner 111. The elastic member 140 abuts between the inner liner 111 and the upper liner 132. Exemplarily, the inner liner 111 is nested in the movable cover 131. The function of the inner liner 111 is to limit the range of movement of the movable cover 131, thereby achieving the purpose of limiting the blade shaft assembly 120.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 In a possible embodiment, the stirring body 110 also includes a stirring cover 112 and a connecting pipe 113, the lining 111 is installed in the stirring cover 112, the connecting pipe 113 is arranged in the stirring cover 112 and connected to the lining 111, and a sliding groove 1131 is formed on the connecting pipe 113.

[0034] Please refer to Figure 1 、 Figure 2 、 Figure 3 In one possible embodiment, the stirring body 110 further includes a sealing ring 114, which is disposed near the second end 122 and abuts between the stirring cover 112 and the connecting tube 113. Exemplarily, the sealing ring 114 is disposed near the blade to prevent water from entering the stirring head 100 when cutting food, thereby preventing damage to internal components of the stirring head 100.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 In one possible embodiment, the stirring body 110 further includes a bottom plate 115 and a steel plate 116. The bottom plate 115 is connected to the connecting pipe 113, and the steel plate 116 is connected to the end of the steel plate 116 facing away from the connecting pipe 113. For example, the bottom plate 115 and the steel plate 116 are disc-shaped as a whole, and the steel plate 116 is arranged at the outermost side. The steel plate 116 is made of stainless steel. Stainless steel can prevent the stirring head 100 from rusting due to long-term contact with water and air, which may affect human health. The side of the steel plate 116 facing away from the bottom plate 115 is the bottom surface 119 of the pipe cover.

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 3 In one possible embodiment, the stirring body 110 includes a linear bearing 117, which is disposed in the sliding groove 1131 and nested on the blade shaft assembly 120. For example, the stirring head 100 of the present application ensures that the blade shaft assembly 120 remains in a vertical state during the sliding process by providing the linear bearing 117, and does not cause the position of the blade shaft assembly 120 to shift during the movement, thereby preventing the height position of the blade from being inconsistent. The design takes into account the consistency of the distance between the blade and the bottom of the tube cover, and can ensure a good cutting effect regardless of whether it is processing large or small foods, thereby avoiding the problem of poor cutting effect that may occur when processing large foods in the existing stirring head 100 with an adjustable distance between the blade and the bottom of the tube cover.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3In one possible embodiment, the stirring body 110 further includes a shock-absorbing block 118, which is disposed between the linear bearing 117 and the sliding groove 1131 and is made of an elastic material. For example, the shock-absorbing block 118 provides space for fine-tuning the blade shaft assembly 120. During rotation, the blade shaft assembly 120 inevitably deflects, which can easily damage internal components over time. Therefore, the shock-absorbing block 118 is embedded in the blade shaft assembly 120 to reduce wear on its components caused by deflection during rotation.

[0038] Please refer to Figure 4 In one possible embodiment, the blade shaft assembly 120 includes a rotating shaft 123 and a blade assembly 124 connected to the rotating shaft 123, with the blade assembly 124 disposed at the second end 122. For example, the pressing assembly 130 is disposed at the first end 121 of the rotating shaft 123, and the blade assembly 124 is disposed at the second end 122. It is understood that when the blade shaft assembly 120 slides due to a large piece of food, a force is applied to the second end 122, and when it slides due to user intervention, a force is applied to the first end 121.

[0039] Please refer to Figure 4 In one possible embodiment, the blade assembly 124 includes a first blade 1241 and a second blade 1242. The first blade 1241 extends gradually closer to the pressing assembly 130 in the radial direction of the rotating shaft 123, and the second blade 1242 extends gradually away from the pressing assembly 130 in the radial direction of the rotating shaft 123. For example, in this embodiment, the first blade 1241 and the second blade 1242 are configured to be arc-shaped. Both the first blade 1241 and the second blade 1242 extend in a direction substantially perpendicular to the central axis of the rotating shaft 123. The difference is that the first blade 1241 is curved upward, while the second blade 1242 is curved downward. This structure allows the blade assembly 124 of the present application to occupy a larger cutting space, thereby improving the cutting efficiency of the mixing head 100. In addition, it should be noted that there are two first blades 1241 and two second blades 1242, and the first blades 1241 and the second blades 1242 are arranged alternately, that is, the angle between adjacent blades is 90°, and the angle between the two first blades 1241 is 180°, and the angle between the two second blades 1242 is 180°.

[0040] Both the first blade 1241 and the second blade 1242 are made of stainless steel, measuring 43 mm in length, 13 cm in width, and 1 mm in thickness. The blades are curved to maximize their contact area with food. The blades are electrically retracted (manually or automatically) within a range of 0-8 mm to accommodate food of varying sizes.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 3 In one possible embodiment, the knife shaft assembly 120 slides within the range of [0,8] mm. For example, Figure 2 The position of the knife shaft assembly 120 shown is the distance between the blade and the bottom surface 119 of the pipe cover is the smallest. At this time, the distance moved by the knife shaft assembly 120 is defined as 0 mm. Figure 3 The position of the knife shaft assembly 120 shown is the distance between the blade and the bottom surface 119 of the tube cover is the largest, and the distance moved by the knife shaft assembly 120 is defined as 8 mm.

[0042] 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 patent application. 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.
