Description

Technical Field

[0001] This utility model belongs to the field of food processors, specifically relating to a detachable multi-sealing structure for a food processor and the food processor thereof. Background Technology

[0002] Food processors, as kitchen appliances that integrate multiple functions such as blending, cutting, grinding, and juicing, are widely popular due to their versatility. To facilitate cleaning the blades, food processors with detachable cups have appeared on the market, exposing the blades for easy cleaning. However, food processors with detachable cups require a higher level of sealing to prevent leakage.

[0003] In the prior art, such as patent document CN107224224B, a blender cup assembly and a blender are disclosed, including a detachably connected shell and a cup. A support is provided inside the shell, and the support abuts against the cup, but does not clamp the sealing gasket. However, the sealing performance of this blender depends on whether the cup and the support are properly abutted. When the cup and the support are not properly abutted, gaps can easily appear at the sealing gasket, leading to leakage from the cup. Therefore, the sealing performance needs to be improved. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model proposes a detachable multi-sealing structure for a food processor and the food processor thereof. The multi-sealing structure is formed by a vertically arranged first sealing surface and a horizontally arranged second sealing surface through sealing components. When the cup body is not installed properly, causing a gap in the second sealing surface, the first sealing surface can still ensure the sealing of the food processor.

[0005] This invention is implemented as follows: a detachable multi-sealed structure for a food processor, comprising a detachable base and a cup body; the cup body has a hollow mixing chamber, and a connecting interface is provided at the lower end of the cup body, which communicates with the mixing chamber; a blade is provided at the upper center of the base, and when the cup body is connected to the base, the blade extends from the connecting interface into the mixing chamber.

[0006] A sealing member is provided at the joint between the base and the cup body, and the sealing member is sleeved on the lower edge of the cup body interface; the base is provided with an annular joint around the knife, and the annular joint is adapted to the sealing member;

[0007] When the cup body is connected to the base, the inner wall of the sealing member abuts against the annular joint, forming a longitudinally arranged first sealing surface; the bottom of the sealing member abuts against the base, forming a transversely arranged second sealing surface. The longitudinally arranged first sealing surface is not completely vertical; it can be inclined left or right along the vertical direction, and the first sealing surface can be a plane, curved surface, wavy surface, or serrated surface. The transversely arranged second sealing surface is not completely horizontal; it can be inclined up or down along the horizontal direction, and the second sealing surface can be a plane, curved surface, wavy surface, or serrated surface. The first sealing surface extends longitudinally, so even if the cup body is not properly installed and causes it to float up or down, the first sealing surface can still maintain a sealing state. The second sealing surface extends transversely, so even if the cup body is not properly installed and floats left or right, the second sealing surface can still maintain a sealing state. When the first and second sealing surfaces cooperate with each other, the cup body can maintain a sealing state regardless of whether it floats up or down or left or right, thus improving the sealing performance of the cup body.

[0008] Preferably, the sealing member includes a mounting bracket and a first sealing ring. The first sealing ring is disposed inside the mounting bracket and is interference-fitted with the annular joint. The first sealing ring includes a first pressing portion that abuts against the annular joint. The inner wall of the first pressing portion abuts against the sealing boss to form a first sealing surface. The bottom of the first pressing portion abuts against the base to form a second sealing surface. The annular joint increases the longitudinal extension length of the bottom, further improving the longitudinal extension length of the first sealing surface, thereby further improving the sealing performance of the first sealing surface.

[0009] Alternatively, the sealing member may include a first sealing ring, which is sleeved on the lower edge of the mating interface.

[0010] Specifically, when the sealing component is a combination of a sealing ring and a mounting bracket, the first sealing ring further includes a second pressing portion that abuts against the cup body. The inner wall of the second pressing portion abuts against the cup body to form a third sealing surface. Since the first sealing ring is not integrally formed with the cup body, the sealing performance between the first sealing ring and the cup body must be ensured when the first sealing ring is connected to the cup body. The third sealing surface is formed by the abutment and sealing between the first sealing ring and the cup body, thereby improving the sealing performance between the first sealing ring and the cup body.

[0011] Specifically, the inner wall of the second pressing part is also provided with an inwardly protruding sealing strip, which makes the second pressing part and the cup body fit together with an interference fit. The sealing strip makes the fit between the first sealing ring and the cup body tighter, further improving the sealing performance between the first sealing ring and the cup body.

[0012] Specifically, at least two sealing protrusions are provided, arranged from the upper and lower parts of the inner wall of the second pressing part towards the middle. This not only makes the fit between the second pressing part and the cup body tighter, but also makes the force on the second pressing part more uniform, further improving the sealing performance between the first sealing ring and the cup body.

[0013] Specifically, the mounting bracket has an L-shaped cross-section and includes a horizontally arranged anti-detachment part. The first sealing ring includes an anti-detachment groove adapted to the anti-detachment part, and the anti-detachment groove abuts against the anti-detachment part. The anti-detachment part is used to support the first sealing ring. Since the first pressing part abuts against the sealing boss, when the cup body is disassembled, the sealing boss will generate a downward frictional force on the first sealing ring. The anti-detachment part can prevent the first sealing ring from coming out of the mounting bracket under the action of friction, thereby improving the reliability of the first sealing ring.

[0014] Preferably, the upper part of the base is provided with a heating plate, the upper end of which has an annular protrusion forming the annular joint. The heating plate is used to heat the food in the mixing chamber, enabling the food processor to cook foods that require heating, thus making the food processor more versatile and improving its practicality.

[0015] Preferably, a second sealing ring is further provided around the annular joint. The second sealing ring includes a third pressing portion adapted to the sealing member. When the base is connected to the cup body, the third pressing portion presses against the outer wall of the sealing member. The second sealing ring increases the sealing surface between the base and the cup body when they are connected, further improving the sealing performance between them.

[0016] Preferably, the sealing component has multiple mounting parts on its periphery, and the mounting parts are installed on the bottom of the cup body by threaded fasteners. When the sealing component ages and fails, the sealing component can be disassembled and replaced individually, which improves the convenience of later maintenance of the sealing component.

[0017] A food processor, comprising the aforementioned detachable multi-sealed food processor structure.

[0018] Preferably, the cup body is provided with a slot, and the base is provided with a locking part that matches the slot. The cup body is engaged with the slot and the locking part by rotation. The slot and the locking part enable quick assembly and disassembly of the base and the cup body, improving the ease of assembly and disassembly of the cup body.

[0019] The beneficial effects of this utility model are:

[0020] This utility model proposes a detachable multi-sealing structure for a food processor and the food processor thereof. The multi-sealing structure is formed by a first sealing surface arranged longitudinally and a second sealing surface arranged laterally through sealing components. When the cup body is not installed properly, causing a gap in the second sealing surface, the first sealing surface can still ensure the sealing performance of the food processor. When the first sealing surface and the second sealing surface cooperate with each other, the cup body can maintain a sealed state regardless of whether it is not installed properly and floats up and down or left and right, thus improving the sealing performance of the cup body.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1-5 As shown, a detachable multi-sealing structure for a food processor includes a detachable base 2 and a cup body 1. The cup body 1 has a hollow mixing chamber, and a connecting port is provided at the lower end of the cup body 1, which communicates with the mixing chamber. A blade is provided at the upper middle part of the base 2. When the cup body 1 is connected to the base 2, the blade extends from the connecting port into the mixing chamber. A sealing member 3 is provided at the joint between the base 2 and the cup body 1, and the sealing member 3 is sleeved on the lower edge of the connecting port of the cup body 1.

[0032] In this embodiment, the sealing member 3 is provided with a plurality of mounting parts 312 on its periphery. The mounting parts 312 are installed on the bottom of the cup body 1 by threaded fasteners. When the sealing member 3 ages and fails, the sealing member 3 can be disassembled and replaced separately, which improves the convenience of the sealing member 3 in the later maintenance.

[0033] The base 2 is provided with an annular engagement portion around the cutter, and the annular engagement portion is adapted to the sealing member 3;

[0034] In this embodiment, a heating plate 21 is provided on the upper part of the base 2. The upper end of the heating plate 21 has an annular protrusion, forming the annular joint portion. The heating plate 21 is used to heat the food in the mixing chamber, enabling the food processor to cook food that requires heating, thus making the food processor more versatile and improving its practicality.

[0035] When the cup body 1 is connected to the base 2, the inner wall of the sealing member 3 abuts against the annular joint to form a longitudinally arranged first sealing surface 33; the bottom of the sealing member 3 abuts against the annular joint to form a transversely arranged second sealing surface 34. The longitudinally arranged first sealing surface 33 is not completely vertical, but can be inclined to the left or right along the vertical direction, and the first sealing surface can be a plane, a curved surface, a wavy surface, or a sawtooth surface.

[0036] In this embodiment, the first sealing surface 33 is a vertically arranged plane. When the cup body 1 is not installed properly and causes it to float up and down, the first sealing surface 33 can still maintain a sealing state.

[0037] The second sealing surface 34, which is set horizontally, is not set completely horizontally. It can be set up and down in the horizontal direction, and the second sealing surface 34 can be a flat surface, a curved surface, a wavy surface or a sawtooth surface.

[0038] In this embodiment, the second sealing surface 34 is a horizontally set plane. When the cup body 1 is not installed properly and floats left or right, the second sealing surface 34 can still maintain a sealing state. When the first sealing surface 33 and the second sealing surface 24 cooperate with each other, the cup body 1 can maintain a sealing state regardless of whether it floats up and down or left and right, thus improving the sealing performance of the cup body 1.

[0039] In this embodiment, the sealing member 3 includes a mounting bracket 31 and a first sealing ring 32. The first sealing ring 32 is disposed inside the mounting bracket 31 and is interference-fitted with the heating plate 21. The first sealing ring 32 includes a first pressing portion 321 that abuts against the heating plate 21. The heating plate 21 is provided with a sealing boss 211 that matches the first pressing portion 321. The inner wall of the first pressing portion 321 abuts against the sealing boss 211 to form the first sealing surface 33. The bottom of the first pressing portion 321 abuts against the heating plate 21 to form the second sealing surface 34. The sealing boss 211 increases the vertical extension length of the heating plate 21, further improving the vertical extension length of the first sealing surface 33, thereby further improving the sealing performance of the first sealing surface 33.

[0040] Specifically, the first sealing ring 32 further includes a second pressing part 322 that abuts against the cup body 1. The inner wall of the second pressing part 322 abuts against the cup body 1 to form a third sealing surface. Since the first sealing ring 32 is not integrally formed with the cup body 1, the sealing performance between the first sealing ring 32 and the cup body 1 must be ensured when the first sealing ring 32 is connected to the cup body 1. The third sealing surface is formed by the abutment and sealing between the first sealing ring 32 and the cup body 1, which improves the sealing performance between the first sealing ring 32 and the cup body 1.

[0041] Specifically, the inner wall of the second pressing part 322 is also provided with an inwardly protruding sealing strip 3221, which makes the second pressing part 322 and the cup body 1 have an interference fit. The sealing strip 3221 makes the fit between the first sealing ring 32 and the cup body 1 tighter, further improving the sealing performance between the first sealing ring 32 and the cup body 1.

[0042] Specifically, the sealing protrusions 3221 are provided in two parts and arranged on the upper and lower parts of the inner sidewall of the second pressing part 322. This not only makes the fit between the second pressing part 322 and the cup body 1 tighter, but also makes the force on the second pressing part 322 more uniform, further improving the sealing performance between the first sealing ring 32 and the cup body 1.

[0043] Specifically, the mounting bracket 31 has an L-shaped cross-section and includes a horizontally arranged anti-detachment part 311. The first sealing ring 32 includes an anti-detachment groove 323 adapted to the anti-detachment part 311, and the anti-detachment groove 323 abuts against the anti-detachment part 311. The anti-detachment part 311 is used to support the first sealing ring 32. Since the first pressing part 321 abuts against the sealing boss 211, when the cup body 1 is disassembled, the sealing boss 211 will generate a downward frictional force on the first sealing ring 32. The anti-detachment part 311 can prevent the first sealing ring 32 from coming out of the mounting bracket 31 under the action of friction, thereby improving the reliability of the first sealing ring 32.

[0044] In this embodiment, a second sealing ring 212 is also provided around the heating plate 21. The second sealing ring 212 includes a third pressing part adapted to the sealing member 3. When the base 2 is connected to the cup body 1, the third pressing part presses against the outer wall of the sealing member 3. The second sealing ring 212 increases the sealing surface between the base 2 and the cup body 1 when the base 2 and the cup body 1 are connected, further improving the sealing performance between the base 2 and the cup body 1.

[0045] Example 2

[0046] like Figure 6 As shown, a food processor includes a detachable multi-sealed food processor structure as described in Embodiment 1.

[0047] In this embodiment, the cup body 1 is provided with a slot 11, and the base 2 is provided with a locking part 22 that matches the slot 11. The cup body 1 is engaged with the slot 11 and the locking part 22 by rotation. The slot 11 and the locking part 22 enable quick assembly and disassembly of the base 2 and the cup body 1, improving the ease of assembly and disassembly of the cup body 1.
