Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to an anti-overflow kitchen mixer. Background Technology

[0002] In modern home and catering kitchens, blenders are widely used as an important food processing device for tasks such as blending fruits and vegetables, preparing fillings, and making beverages. Driven by a motor, the blades rotate at high speed to cut, stir, and mix ingredients, greatly improving food processing efficiency and bringing convenience to the cooking process.

[0003] Traditional kitchen blenders commonly suffer from spillage during use. Ingredients with foaming properties produce a lot of foam during blending. As the foam expands, it rises to the top of the container and overflows, causing not only a significant waste of food but also contaminating the blender surface and kitchen countertop, increasing the difficulty and intensity of cleaning. Most methods rely on increasing the height of the container or using a well-sealed lid to reduce spillage, but the effect is not ideal and it is still difficult to prevent foam from overflowing. Therefore, an anti-overflow kitchen blender has emerged. Utility Model Content

[0004] The purpose of this invention is to provide an anti-overflow kitchen mixer, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0028] Example

[0029] Reference Figures 1 to 8 This is an embodiment of the present invention, which provides an overflow-proof kitchen mixer, comprising:

[0030] The base 101, the limiting groove 102 opened on the top of the base 101, the output shaft 103 rotatably connected to the center of the limiting groove 102 via a bearing, the housing 104 set on the top of the base 101, the limiting boss 105 fixedly installed on the bottom of the housing 104, the rotating shaft 106 rotatably connected to the bottom of the housing 104, the bolt 107 fixedly connected to the end of the rotating shaft 106, the blade 108 movably installed on the outer periphery of the bolt 107, the bubble suppression ring assembly 109 movably installed on the outer periphery of the bolt 107, the vertical rib 110 fixedly installed on the inner side wall of the housing 104, the flow blocking ring 111 fixedly installed on the inner side wall of the housing 104, the cup lid 112 inserted into the end of the housing 104, the sealing plunger 113 fixedly installed on the upper surface of the cup lid 112, and the gravity valve assembly 114 set in the circular groove on the lower surface of the cup lid 112.

[0031] A housing 104, made of stainless steel, is installed on top of the base 101. A limiting boss 105, whose shape matches a limiting groove 102, is fixedly installed at the bottom of the housing 104. When the housing 104 is placed on the base 101, the limiting boss 105 is embedded in the limiting groove 102, achieving precise positioning between the housing 104 and the base 101. Six vertical ribs 110, made of metal, are fixedly installed on the inner wall of the housing 104, evenly distributed on the inner wall. A flow-blocking ring 111, made of stainless steel and circular in shape, is fixedly installed above the vertical ribs 110 on the inner wall of the housing 104, perpendicular to the inner wall. A cup lid 112, made of plastic and matching the shape of the end of the housing 104, is inserted into the end of the housing 104 to achieve a seal. A sealing plunger 113, made of rubber, is fixedly installed on the upper surface of the cup lid 112 to seal the relevant holes on the cup lid. A gravity valve assembly 114 is installed in the circular groove on the lower surface of the cup lid 112 to release pressure when the pressure inside the housing is too high.

[0032] Specifically, the foam suppression ring assembly 109 includes a mounting ring 109a axially fixed to the outer periphery of the bolt 107 by a nut, a connecting post 109b fixedly installed on the side wall of the mounting ring 109a, a foam suppression ring 109c fixedly installed at the end of the connecting post 109b, and a turbulence column 109d fixedly installed on the lower surface of the foam suppression ring 109c.

[0033] Furthermore, the defoaming ring assembly 109 includes a mounting ring 109a, which is made of metal, circular in shape, and whose inner diameter matches the outer diameter of the bolt 107. It is axially fixed to the outer circumference of the bolt 107 by a nut and can rotate with the bolt 107. Three connecting posts 109b, also made of metal, are evenly fixedly installed on the side wall of the mounting ring 109a. A defoaming ring 109c, made of stainless steel and umbrella-shaped, is fixedly installed at the end of each connecting post 109b, creating downward air pressure to suppress foam rise. Multiple turbulence columns 109d, made of metal, are evenly fixedly installed on the lower surface of the defoaming ring 109c. These turbulence columns 109d further disperse bubbles and enhance the defoaming effect when the defoaming ring 109c rotates.

[0034] Preferably, the gravity valve assembly 114 includes a guide post 114a fixedly installed at the bottom of the groove on the lower surface of the cup lid 112, a valve disc 114b slidably connected to the outer periphery of the guide post 114a, and a gravity block 114c fixedly installed on the upper surface of the valve disc 114b.

[0035] It should be noted that the gravity valve assembly 114 includes five guide posts 114a, which are made of metal and are cylindrical in shape. They are vertically fixed at the bottom of the groove on the lower surface of the cup lid 112. The guide posts 114a are evenly distributed. A valve disc 114b is slidably connected to the outer periphery of the guide posts 114a. The valve disc 114b is made of food-grade silicone and is circular in shape. A guide hole is opened on its edge corresponding to the position of the guide post 114a. The guide post 114a passes through the guide hole to ensure that the valve disc 114b can slide smoothly up and down along the guide post 114a. A gravity block 114c is fixedly installed at the center of the upper surface of the valve disc 114b. The gravity block 114c is made of metal. When the air pressure inside the housing reaches the standard atmospheric pressure, the upward thrust generated by the air pressure causes the gravity block 114c to move upward, pushing the sealing plunger 113 out of the pressure relief hole.

[0036] When in use, connect the base 101 to the power supply and turn on the device switch. At this time, the output shaft 103 starts to rotate, driving the rotating shaft 106 to rotate through the coupling. This causes the bolt 107, blade 108, and defoaming ring assembly 109 to rotate together. The rotating blade 108 stirs the food inside the shell. During the stirring process, the defoaming ring 109c of the defoaming ring assembly 109 rotates with the bolt 107, creating downward air pressure to suppress the rise of foam. At the same time, the turbulence column 109d on the lower surface of the defoaming ring 109c disperses the bubbles, enhancing the defoaming effect. The vertical ribs 110 on the inner wall of the shell 104 guide the liquid to the cup wall, forming a centrifugal barrier to reduce liquid surging and foam generation. The flow-blocking ring 111 blocks the rising liquid and foam, causing them to flow back and further preventing overflow. When the air pressure generated by stirring inside the shell is too high, the valve disc 114b of the gravity valve assembly 114 is lifted upward along the guide post 114a under the action of air pressure. The thrust causes the gravity block 114c to move upward, pushing the sealing plunger 113 out of the pressure relief hole to release pressure through the pressure relief hole.

[0037] In summary, the foam suppression ring 109c of the foam suppression ring assembly 109 rotates with the bolt 107 to generate downward air pressure, which can effectively suppress the rise of foam. At the same time, the turbulence column 109d on its lower surface can disperse the bubbles, reducing the amount of foam from the source and reducing the risk of overflow. The vertical ribs 110 on the inner wall of the shell 104 guide the liquid to the cup wall to form a centrifugal barrier, reducing the upward flow of liquid. The flow obstruction ring 111 blocks the rising liquid and foam, causing them to flow back. The dual function further prevents the material from overflowing, avoiding the waste of food caused by overflow. The gravity valve assembly 114 of the self-balancing pressure relief cap automatically lifts to relieve pressure when the air pressure inside the shell is too high, preventing the material from gushing out due to excessive pressure, ensuring the stability of the stirring process and reducing the loss of food.
