Description

Technical Field

[0001] This utility model relates to the field of food processor structure technology, specifically to a food processor with a magnetic micro-switch and waterproof design. Background Technology

[0002] A food processor is a cooking device used to blend ingredients to a specific state. It is equipped with a blending chamber and a blending component. Some models integrate a heating unit to achieve simultaneous heating during the blending process.

[0003] In existing designs, food processors typically consist of a base, a cup body, and a lid. The cup body forms the food processing chamber, while the electrical circuitry and power supply are concentrated inside the base. To ensure safety, existing designs incorporate a microswitch on the base and an axially movable guide rod between the base and the lid, with a corresponding pin on the lid. Simultaneously, magnetic components with opposite poles are positioned at the bottom of the guide rod and at the microswitch. When the lid and cup body are assembled, the pin presses down on the guide rod, causing it to move axially. The repulsive force between the like poles of the magnetic components triggers the microswitch to conduct the circuit, thus achieving a safe logic where the food processor only operates when the lid is closed.

[0004] The repulsive force causes the top cover to continuously experience the tendency to separate from the upward lifting guide rod and the pin. Especially under heating conditions, the steam pressure accumulated in the cooking cavity will further intensify the lifting force, posing a risk that the top cover will unexpectedly open and stop suddenly during machine operation.

[0005] In addition, food processors require cleaning and maintenance, and liquid may spill during operation. This liquid may seep into the pins and guide rods and spread to the microswitch area, causing electrical short circuit failure and resulting in safety risks. Summary of the Invention

[0006] In response to the problems in related technologies, this utility model proposes a food processor with a magnetic micro-switch and waterproof design, which can improve the waterproof performance of the food processor and the connection stability between the lid and the body during operation.

[0007] This utility model is implemented as follows:

[0008] A waterproof food processor with a magnetic micro switch includes a base, a cup body, and a cup lid; the base is equipped with a micro switch, which includes a free end and is fixedly connected to a first magnetic block; the first magnetic block is located near the upper surface of the base.

[0009] The cup body is positioned above the base and is sealed to the base. A cover is provided above the base and outside the cup body. A guide rod that can move up and down is provided between the cover and the cup body. A first spring is fitted at the lower end of the guide rod, and the bottom of the first spring abuts against the base. A second magnetic block and a third magnetic block are respectively provided at the lower and upper ends of the guide rod. The second magnetic block is located directly above the first magnetic block.

[0010] The cup lid matches the size of the upper opening of the cup body; the cup lid and the cup body / cover are screwed together to limit the axial position of the cup lid; a fourth magnetic block is also provided on the cup lid; after the cup lid is assembled, the fourth magnetic block is located directly above the third magnetic block;

[0011] The first magnetic block and the second magnetic block are isolated from each other and have the same polarity on opposite sides; the third magnetic block and the fourth magnetic block are isolated from each other and have the same polarity on opposite sides.

[0012] Two magnetic blocks with the same polarity on opposite sides will generate increasing repulsive force when they are brought close together. After the lid is assembled, the repulsive force generated by the third and fourth magnetic blocks will press down the guide rod. The pressed guide rod will generate repulsive force between the first and second magnetic blocks, causing the free end to move and opening the micro switch, thus connecting the food processor circuit. After the lid is separated, the repulsive force above disappears, and the guide rod will return to its original position under the action of the repulsive force below and the elastic force of the first spring. At the same time, the micro switch will reset, and the food processor circuit will be disconnected.

[0013] The above design, with its multi-layered isolation, utilizes the repulsive force of magnetic blocks to activate the microswitch inside the base, ensuring water resistance and waterproofing. Simultaneously, the screw-on lid securely fastens the lid to the blender body, with upper and lower limits preventing it from opening due to spring force, repulsive force, or the normal operating pressure of the blender. This multi-faceted synergy effectively balances the overall safety and convenience of the blender.

[0014] As a further optimization of the above solution, the outer side of the cup lid has an outwardly protruding extension; directly below the extension, the cover body forms a flat portion; the guide rod and its third magnet are both located directly below the flat portion;

[0015] The outer side of the extension has a protruding retaining strip; the outer edge of the surface of the flat part has an upwardly protruding and inwardly bent limiting part, the limiting part and the flat part forming a sliding groove; the two ends of the sliding groove are open; the retaining strip matches the sliding groove;

[0016] After the cup lid is assembled with the upper opening of the cup body, the cup lid is rotated relative to the cup body, and the locking strip is inserted into the sliding groove, which is the screw-fit.

[0017] As a further optimization of the above solution, a fixed directional cylinder is provided on the upper surface of the base or above the base, and an directional groove is formed inside the directional cylinder; the directional groove points to the first magnetic block;

[0018] The bottom of the guide rod is a guide portion; the radial dimension of the guide portion is smaller than that of the guide rod body; the radial dimension of the guide portion is adapted to the directional groove; the guide portion extends into the directional groove.

[0019] The first spring is sleeved on the outer periphery of the directional part and is confined between the directional cylinder and the guide rod body.

[0020] The directional cylinder and guide section are designed so that each up-and-down movement / extension / retraction of the guide rod points to the first magnetic block, ensuring the stable formation of the repulsive force below.

[0021] As a further optimization of the above solution, the free end is a reset button; the reset button is located on the upper surface of the micro switch; the first magnetic block is fixed on the upper surface of the reset button.

[0022] In this invention, the "reset button" does not refer to a standalone product, but rather to the structural features and function of a moving part on a micro switch. Inside the micro switch, a spring or other elastic structure supports the automatic reset of the reset button, enabling the button portion of the micro switch to be energized when pressed and de-energized when released.

[0023] As a further optimization of the above solution, the upper surface of the micro switch has a raised reset button; the micro switch also includes a pressure plate; one end of the pressure plate is hinged to the micro switch body, and the other end is the free end; the reset button is located below the pressure plate and close to the hinge position.

[0024] Under the action of repulsive force, the pressure plate rotates downward and presses down on the reset button. At this time, the pressure plate acts as a lever. Compared with the previous method of directly applying repulsive force to the reset button, the required repulsive force is lower, that is, the magnetic / magnetic force requirement of the magnetic component is lower.

[0025] As a further optimization of the above solution, in the pressing tablet, the free end is bent upwards and in the opposite direction to form a hook portion; the pressing tablet has protruding limiting wings on both sides near the hook portion, and the limiting wings are bent vertically upwards relative to the pressing tablet;

[0026] The first magnetic block is embedded between the two limiting wings and is fastened and fixed by the hook portion.

[0027] As a further optimization of the above solution, the lower end of the guide rod has a slot with an opening facing downwards, and the upper end of the guide rod has a slot with an opening facing upwards; the second magnetic block and the third magnetic block are respectively embedded in the two slots.

[0028] As a further optimization of the above solution, the extension has a downwardly protruding C-shaped protrusion; the fourth magnetic block is interference-fitted into the C-shaped protrusion; a detachable baffle is provided below the C-shaped protrusion; the baffle is formed as the lower surface of the extension.

[0029] As a further optimization of the above solution, a chassis is provided on the upper side of the base, and a drive device is provided inside the base. The drive device is equipped with a transmission shaft that extends upward through the chassis and is sealed to the chassis. A stirring assembly is connected to the upper end of the transmission shaft. A top edge extending upward around the chassis is provided on the base, and the top edge is higher than the stirring assembly.

[0030] The bottom of the cup is open, and the bottom of the cup is sealed and pressed against the periphery of the base to form a cooking cavity surrounding the stirring assembly;

[0031] The bottom of the cover has an annular groove for the top edge to be inserted; the base is located in the center of the annular groove;

[0032] The outer side of the top edge is provided with a plurality of first buckles; the inner side of the annular groove is provided with a plurality of second buckles; when the cover and the base are rotated into position, the first buckles are located on the outer periphery of the top edge, and the first buckles and the second buckles are engaged with each other one by one.

[0033] The cover and base are detachably connected, as are the base and cup, making it easy to clean the food processor's cup and adjacent parts, resulting in a more thorough and complete cleaning.

[0034] Furthermore, the chassis is a heating plate.

[0035] As a further optimization of the above solution, the base has a protrusion on its side; the protrusion is provided with a limiting rod that can move up and down; the limiting rod has a protruding button on its side; the protrusion has a sliding flat opening on its side for the button to protrude; a second spring is provided between the lower end of the limiting rod and the bottom of the protrusion.

[0036] The outer side of the cover is provided with an integrally connected handle; the bottom of the handle is hollowed out; the upper end of the limiting rod protrudes through the upper surface of the protrusion and enters the interior of the handle;

[0037] When the button is pressed down along the sliding flat opening, the limiting rod moves down, the second spring is compressed, and the upper end of the limiting rod retracts into the protrusion; when the button is released, the limiting rod is reset by the action of the second spring.

[0038] The limiting rod and its cooperating structure can limit and fix the cover and base after assembly. When disassembling the cover and base, pressing the button will allow the cover and base to rotate in the opposite direction and separate.

[0039] The beneficial effects are as follows:

[0040] (1) This utility model provides a food processor with a magnetic micro switch and waterproof. The conductive structures are physically spaced apart from each other. The micro switch is turned on and off by non-contact conductive control through the repulsive force characteristics between the magnetic blocks, which effectively ensures the water-proof / waterproof performance of the circuit system and avoids the micro switch from short-circuiting due to contact with liquid when the food processor is cleaned or liquid overflows.

[0041] (2) The screw-on lid and upper and lower limit design ensure stable assembly and eliminate the risk of accidental opening due to magnetic force, elastic working pressure, or their combined effect. This significantly enhances the overall reliability and safety of the food processor.

[0042] (3) This utility model also provides a detachable solution for the food processor, which effectively improves the convenience of disassembling, cleaning and maintaining the food processor. Attached Figure Description

[0074] The limiting rod 1-8 and its cooperating structure can limit and fix the cover 4 and base 1 after assembly. When disassembling the cover 4 and base 1, pressing button 1-8-1 will rotate the cover 4 and base 1 in the opposite direction to separate them.

[0076] In this embodiment, the extension 3-1 has a downwardly protruding C-shaped protrusion 3-3; a fourth magnetic block 10 is fixedly installed inside the C-shaped protrusion 3-3. A detachable baffle 3-4 is provided below the C-shaped protrusion 3-3; the baffle 3-4 is formed as the lower surface of the extension 3-1.

[0077] A guide rod 6 that can move up and down is provided between the cover body 4 and the cup body 2. The bottom of the guide rod 6 is a guide part 6-1; the radial dimension of the guide part 6-1 is smaller than that of the main body of the guide rod 6; the guide part 6-1 is equipped with a first spring 6-2.

[0078] The upper end of the guide rod 6 has an upward-opening slot; the lower end of the guide rod 6, that is, the lower end of the guide portion 6-1, has a downward-opening slot. A third magnet 9 and a second magnet 8 are respectively fixedly installed in the two slots. The guide rod 6 and its third magnet 9 are both located directly below the flat portion 4-4.

[0079] A fixed directional cylinder 1-11 is provided above the base 1, and a vertically oriented directional groove 1-12 is formed inside the directional cylinder 1-11. The radial dimension of the guide part 6-1 is adapted to the directional groove 1-12, and the guide part 6-1 extends into the directional groove 1-12. A first spring 6-2 is sleeved on the outer periphery of the directional part and is limited between the directional cylinder 1-11 and the main body of the guide rod 6; the first spring 6-2 abuts against the directional cylinder 1-11. A first magnetic block 7 is provided inside the base 1, and the directional groove 1-12 points to the first magnetic block 7, that is, the second magnetic block 8 points to the first magnetic block 7, and the second magnetic block 8 is located directly above the first magnetic block 7.

[0080] The base 1 contains a micro switch 11, which includes a free end. Specifically, in this embodiment, the upper surface of the micro switch 11 has a raised reset button 1-8-1; the micro switch 11 also includes a pressure plate 11-2; one end of the pressure plate 11-2 is hinged to the body of the micro switch 11, and the other end is the free end; the reset button 1-8-1 is located below the pressure plate 11-2 and near the hinge position.

The pressed guide rod 6 causes the first and second magnetic blocks 8 to generate repulsive forces, which drives the free end to move and causes the micro switch 11 to open, thus connecting the food processor circuit. After the lid 3 is separated, the upper repulsive force disappears, and the guide rod 6 returns to its original position under the action of the lower repulsive force and the elastic force of the first spring 6-2. At the same time, the micro switch 11 returns to its original position, and the food processor circuit is disconnected.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
