Description

Technical Field

[0001] The utility model relates to the field of household appliances, and in particular to a reinforced sealing structure of a split-type food processor and the food processor. Background Art

[0002] Existing food processors such as wall-breaking machines and soymilk machines process food by grinding and stirring. The general structure of existing split-type food processors includes a main unit, a cup body and a stirring blade. The upper end of the main unit is open, and a heating plate is provided at the upper end opening. A motor is fixedly installed inside the main unit. A connecting hole is provided in the middle of the heating plate. The cup body is detachably arranged on the upper side of the heating plate. The stirring blade is arranged in the cup body, and the output shaft of the motor is connected to the stirring blade through the connecting hole. In order to improve the sealing performance of the wall-breaking machine, a sealing ring is provided on the outer ring of the heating plate to prevent juice or residue from entering the main unit through the gap between the heating plate and the cup body. Unlike the one-piece cup body that almost does not need to be disassembled, the split-type cup body needs to be repeatedly disassembled, so that the lower part of the cup body and the sealing ring need to be reciprocated and squeezed, which easily causes the sealing ring to curl and warp, and may cause food residues and juice to penetrate between the sealing ring and the bottom of the cup body, hiding dirt, which is not conducive to cleaning and is also easy to cause hygiene problems. Summary of the invention

[0003] The first invention objective of the utility model is to solve the problem that the sealing ring of the existing food processor is easy to warp and infiltrate residues, and to provide a reinforced sealing structure of a split-type food processor.

[0004] In order to achieve the above invention objectives, the utility model adopts the following technical solutions:

[0005] The reinforced sealing structure of a split-type food processor comprises a detachably mounted main unit and a cup body, wherein a heating plate is provided on the upper end surface of the main unit, and a motor is provided below the heating plate, a stirring knife is provided on the upper side of the heating plate, and a driving shaft of the motor provided below the heating plate passes through the heating plate and is drivingly connected to the stirring knife; a sealing ring is provided along the peripheral edge of the heating plate and is sealed to the heating plate, the radial width of the sealing ring is greater than the axial height, and a radially extending reinforcing mechanism is provided inside the sealing ring; a supporting portion is provided on the lower side of the sealing ring, and a pressing portion and a fixing portion are radially included on the upper side of the sealing ring from the inside to the outside, and a first mounting frame press-fitted with the fixing portion, the first mounting frame and the supporting portion fix the sealing ring on the main unit, and the pressing portion is detachably abutted against the bottom of the cup body; the reinforcing mechanism extends to below the pressing portion and the fixing portion respectively.

[0006] The reinforced sealing structure of the utility model can be applied to split-type food processors. Since the sealing ring is provided with a reinforcing mechanism, the overall strength of the sealing ring, especially the radial strength, can be effectively improved on the basis of ensuring the flexibility and compressibility of the sealing ring edge. Compared with the prior art, the sealing ring of the utility model will not curl or flanging, and can prevent food residues and juice from entering the main machine through the sealing ring, which is more conducive to cleaning and machine maintenance.

[0007] Furthermore, the support portion includes a second mounting frame and an edge extension portion of the heating plate, the edge extension portion extends between the sealing ring and the second mounting frame, and extends to below the fixing portion. In this solution, the fixing portion of the sealing ring and the edge extension portion of the heating plate are sandwiched between the first mounting frame and the second mounting frame, so that the sealing ring and the heating plate are fixed by the cooperation of the two.

[0008] Furthermore, the first mounting frame extends downward along the outer end of the sealing ring and is fixedly connected to the mainframe, and there is a gap between the outer end of the sealing ring and the first mounting frame radially outward. In this solution, there is a gap between the outer end of the sealing ring and the first mounting frame, which can avoid friction resistance when the first mounting frame is assembled downward.

[0009] Furthermore, the lower end of the cup body is open, and a rounded corner is provided at the bottom thereof, and the rounded corner presses against the pressing part of the sealing ring, and the diameter of the rounded corner at the bottom of the cup body is 0.7-2mm, and the distance between the sealing ring and the upper end of the reinforcing mechanism is greater than 2mm. In this solution, the distance between the reinforcing mechanism and the upper end of the sealing ring is greater than 2mm, and when the cup body presses against the sealing ring, the sealing ring produces a downward concave deformation, and the deformation is sufficient to cover the rounded corner at the bottom of the cup body, thereby avoiding water seepage and residue seepage due to the small contact area between the bottom of the cup body and the sealing ring.

[0010] Furthermore, the reinforcing mechanism and the sealing ring are integrally formed by a secondary injection molding process. Alternatively, the reinforcing mechanism and the sealing ring are integrally formed by a rubber coating process. Alternatively, the reinforcing mechanism and the sealing ring are assembled and formed by gluing. Since the combined structure of the reinforcing mechanism and the sealing ring is simple, it can be applied to a variety of processing methods.

[0011] Furthermore, the reinforcing mechanism is a reinforcing sheet.

[0012] Furthermore, a first convex edge is provided on the inner side of the first mounting frame, a first convex wall located at the lower side of the edge extension is provided on the upper end ring of the second mounting frame, and the sealing ring and the edge extension are provided between the first convex edge and the first convex wall.

[0013] Furthermore, a second limiting groove is provided on the first convex edge, the edge extension portion is clamped in the second limiting groove, and the width of the sealing ring is greater than the width of the edge extension portion to cover the gap between the edge extension portion and the second limiting groove.

[0014] Furthermore, a second convex edge is provided on the lower side of the first mounting frame, a first limiting groove is formed between the first convex edge and the second convex edge, the first convex wall is located in the first limiting groove, and the side wall of the first convex wall abuts against the first limiting groove.

[0015] Another invention object of the utility model is to provide a food processor, which is a split-type food processor, including the reinforced sealing structure of the above scheme. Compared with the prior art, the food processor of the utility model uses the reinforced sealing structure of the above scheme, so that the sealing ring is not easy to curl or flanging, and has a higher sealing performance. Moreover, when the cup body is assembled on the main machine, the downward concave deformation of the sealing ring covers the fillet at the bottom of the cup body, further strengthening the sealing performance of the food processor and preventing water and residue from leaking.

[0030] Embodiment 1:

[0031] See also Figure 1-10As shown, this embodiment discloses a reinforced sealing structure of a split-type food processor 8, wherein the food processor 8 comprises a detachably mounted main unit 81 and a cup body 82, wherein the upper end surface of the main unit 81 is provided with a heating plate 2, and a motor 84 is provided below the heating plate 2, a stirring blade 83 is provided on the upper side of the heating plate 2, and a driving shaft of the motor 84 provided below the heating plate 2 passes through the heating plate 2 and is drivingly connected to the stirring blade 83; a sealing ring 24 is provided along the peripheral edge of the heating plate 2 and is sealed to the heating plate 2, and the radial width of the sealing ring 24 is The sealing ring 24 has a support portion on its lower side, and an upper side of the sealing ring 24 includes a pressing portion 244 and a fixing portion 243 from the inside to the outside in the radial direction, and also includes a first mounting frame 3 press-fitted with the fixing portion 243.

[0052] Embodiment 2:

[0053] This embodiment discloses a food processor 8, which is a split-type food processor 8 and is provided with the reinforced sealing structure of the first embodiment.

[0054] Specifically, the food processor 8 of the present embodiment includes a main unit 81, a cup body 82 and a mixing blade 83. The main unit 81 includes at least a shell 80, a motor 84 and the reinforced sealing structure of the first embodiment. The upper end of the shell 80 is open, the heating body 21 is arranged at the upper end of the second mounting frame 4, and the sealing ring 24 is arranged at the outer periphery of the heating body 21. The first mounting frame 3 is arranged around the upper part of the shell 80, so that the outer periphery of the heating body 21 and the sealing ring 24 are clamped between the first mounting frame 3 and the second mounting frame 4, and the upper end opening of the shell 80 is sealed. The motor 84 is fixed to the inside of the shell 80 through the second mounting frame 4, and its driving output end 841 protrudes upward. Regarding the heating body 21, the heating body 21 is matched with a first connecting through hole 23, and the second mounting frame 4 is matched with a second connecting through hole 46, and the first connecting through hole 23 and the second connecting through hole 46 are sealed with the drive output end 841; the lower end of the cup body 82 is open, and its bottom is provided with a rounded corner, and the diameter of the rounded corner at the bottom of the cup body 82 is 0.7-2mm, and the cup body 82 can be detachably assembled on the main unit 81. When it is assembled on the main unit 81, the rounded corner at its bottom presses against the upper side of the sealing ring 24, so that the sealing ring 24 produces a downward concave deformation in height to cover the rounded corner; the stirring knife 83 is located in the cup body 82 and is connected to the drive output end 841.

[0055] The cup body 82 further comprises a cup cover 824, an outer cup 822 covering the inner cup 821 and a cup holder 825 disposed at the bottom of the inner cup 821. The cup holder 825 is detachably rotatably connected to the main unit 81. The inner cup 821 is a cylindrical structure, and a flange 823 is disposed on its lower side. The flange 823 and the corner of the bottom of the inner cup 821 form the above-mentioned fillet. A slot 826 is formed between the flange 823 of the inner cup 821 and the outer wall of the inner cup 821. An annular side wall is disposed on the inner side of the cup holder 825. The inner cup 821 is inserted into the annular side wall and the bottom of the annular side wall is inserted into the slot 826, and the two are fixedly connected as a whole. The bottom of the inner cup 821 is downwardly abutted against the upper side of the sealing ring 24. The diameter of the corner fillet between the bottom of the inner cup 821 and the flange 823 is between 0.7mm and 2mm. Since the distance between the sealing ring 24 and the reinforcing rib is more than 2 mm, the above-mentioned setting method can ensure that when the bottom of the cup is pressed downward to the sealing ring 24 to be recessed, the resulting recessed amount can cover the corner between the bottom of the inner cup 821 and the flange 823, thereby improving the sealing effect between the sealing ring 24 and the inner cup 821 and preventing food residues from entering the main unit 81.

[0056] Since the food processor 8 of this embodiment applies the reinforced sealing structure of the above-mentioned scheme, the sealing ring 24 is not easy to curl or bend 823, and has a higher sealing performance. In addition, when the cup body 82 is assembled on the host 81, the downward concave deformation of the sealing ring 24 covers the rounded corners at the bottom of the cup body, further strengthening the sealing performance of the food processor 8 and preventing water and residue from leaking.
