Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a sealing structure for preventing food residues and a mixer. Background Art

[0002] In the early days of food processing, people usually used manual stirring or simple mechanical stirring to mix ingredients. However, this method is inefficient and it is difficult to ensure uniform mixing of ingredients. With the advancement of technology, food mixers gradually appeared and have been widely used.

[0003] Food blenders use high-speed rotating blades or blenders to quickly mix and stir ingredients, thereby achieving efficient food processing. At the same time, food blenders are also equipped with different blenders and accessories to adapt to different types of ingredients and processing needs.

[0004] Many blender designs on the market currently have obvious deficiencies in cup sealing. Most blenders simply seal the mouth of the cup, but ignore the sealing problem at the joint between the top of the blade and the cup. This design defect causes juice or food to easily splash out, leak, or get stuck from the gap between the top of the blade and the cup during the blending process, which not only affects the blending effect and makes the blended juice less delicate, but also brings cleaning troubles and potential leakage risks to users, which not only increases the difficulty of cleaning, but also may cause bacteria to grow, affecting the sanitary quality of the next blended food. In addition, due to the loose seal, the blender is also at risk of leakage during carrying or moving, which may cause inconvenience to the user and may even damage the blender or surrounding items.

[0026] See also Figures 1 to 5 , the utility model provides a technical solution:

[0027] A sealing structure and a blender for preventing food residues, comprising a blending cup 2, a main unit 3 and a sharing cup 4, wherein the main unit 3 is snap-fitted to the inner side of the bottom of the blending cup 2, the blending cup 2 is inserted into the sharing cup 4, a crushing bin 20 is provided at the upper end of the main unit 3, the inner wall of the sharing cup 4 is tightly connected to the outer wall of the blending cup 2 through a sealing ring 5, a base 21 is screwed to the lower end of the blending cup 2, a sealing pad 6 is provided at the joint between the blending cup 2 and the bottom end of the main unit 3, a gap is provided between the inner wall of the blending cup 2 and the outer wall of the main unit 3 to form an easy-to-stuck material area 19, a sealing ring 7 is provided in the easy-to-stuck material area 19 near the opening end of the crushing bin 20, for preventing the food to be crushed from entering the easy-to-stuck material area 19 through the crushing bin 20, and this sealing design significantly enhances the sealing between the blending cup 2 and the main unit 3, ensuring that food residues or liquids cannot enter the easy-to-stuck material area 19 between the blending cup 2 and the main unit 3.

[0028] Specifically, a sealing groove 8 is provided on the outer side of the upper part of the main machine 3, and a sealing ring 7 is sleeved in the sealing groove 8. The waterproof ribs 9 on the sealing ring 7 are tightly connected to the inner wall of the mixing cup 2. The sealing ring 7 and the sealing pad 6 are added at the connection between the upper part of the main machine 3 and the bottom of the mixing cup 2 for sealing, which can effectively improve the sealing performance and prevent the pulp or other substances from entering the gap between the mixing cup 2 and the main machine 3. This design can effectively reduce the leakage problem that may occur when the machine is running, and also help to keep the inside of the machine clean and hygienic. In addition, the possibility of leakage of pulp or other substances can be further reduced. This close contact design can also reduce the gap generated by the mixing blade 12 when it rotates.

[0029] A blender comprises the above-mentioned sealing structure for preventing food residues.

[0030] Specifically, a driving shaft 11 is disposed in the crushing bin 20 , a stirring blade 12 is installed on the top of the driving shaft 11 , and the driving shaft 11 is connected to a power output end of a motor 10 disposed inside the main machine 3 .

[0031] Specifically, the upper end cover of the mouth of the stirring cup 2 is connected with the stirring cup cover 1, the bottom of the stirring cup 2 is provided with a base 21 and the outer side of the bottom of the stirring cup 2 is provided with an external thread 13, the inner side of the base 21 is provided with an internal thread 14, the stirring cup cover 1 is threadedly screwed with the mouth of the stirring cup 2, the outer side of the bottom of the stirring cup 2 is also provided with an external thread 13, the inner side of the base 21 is provided with an internal thread 14, the bottom of the stirring cup 2 can be threadedly screwed with the base 21, and the stirring cup cover 1 and the stirring cup 2 can be easily assembled or disassembled for daily cleaning and maintenance by threaded screwing.

[0032] Specifically, a groove 15 is provided on the outer side of the lower part of the blending cup 2, and a sealing ring 5 is installed in the groove 15. The waterproof ribs 9 of the sealing ring 5 are tightly connected with the inner wall of the sharing cup 4. The sealing ring 5 will be placed in the groove 15 on the outer wall of the blending cup 2. When the blending cup 2 is inserted into the sharing cup 4, the sealing ring 5 will be in close contact with the outer wall of the blending cup 2 to form a barrier, thereby preventing the sharing cup 4 from falling off the blending cup 2. Since the sealing ring 5 has a certain elasticity, it can adapt to blending cups of different sizes and shapes to ensure the effectiveness of the sealing effect. At the same time, the sealing ring 5, the sealing ring 7 and the sealing pad 6 are usually made of durable materials, such as rubber or silicone, to ensure that they can withstand repeated pressure and friction during the use of the blender.

[0033] Specifically, the waterproof ribs 9 are provided with multiple lines and are arc-shaped. The design of multiple waterproof ribs 9 increases the contact area between the side walls, thereby improving the sealing performance. Each waterproof rib 9 can effectively prevent liquid or food residue from leaking through the gaps, ensuring the waterproof effect of the blender.

[0034] Specifically, an outer casing 16 is disposed on the outer side of the mixing cup 2 , and a handle 17 is installed on the outer casing 16 .

[0035] Specifically, a non-slip and heat-insulating sleeve 18 is provided on the outer side of the sharing cup 4 .

[0036] The working principle of this embodiment is as follows: during specific use, the sealing ring 7 is arranged on the contact surface of the main unit 3 and the stirring cup 2 to provide an additional sealing effect. When the main unit 3 is connected to the stirring cup 2, the sealing ring 7 will be compressed to fill any small gap between the two, thereby shortening the distance of the easy-to-stuck area 19 between the stirring cup 2 and the main unit 3 to prevent food or other substances from passing through. A motor 10 is arranged inside the main unit 3, and the power output end of the motor 10 is connected to the drive shaft 11. The stirring blade 12 installed on the top of the drive shaft 1 can rotate under the drive of the motor 10 to stir and mix the food in the stirring cup 2. The stirring cup cover 1 is tightened to cover the top of the stirring cup 2 to ensure that the contents will not overflow from the top during the stirring process, thereby ensuring the smooth progress of the stirring process. The sharing cup 4 is arranged on the outside of the main unit 3 and the stirring cup 2, and together with the sealing ring 5, provides additional support and protection for the stirring cup 2.
