Description

Technical Field

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

[0002] Food processing equipment such as food processors, blenders, and mixers (hereinafter collectively referred to as "food processors") are core appliances in modern kitchens, integrating high-speed cutting, blending, and pulverizing functions. Some high-end models (such as heated blenders and soy milk makers) also have heating and cooking capabilities. Their core structure typically includes: a base (containing a drive module, control circuit, and heating unit), a cup body (forming the processing chamber, with a built-in rotating blade assembly), and a detachable lid. During operation, the motor drives the blade assembly to rotate at a high speed of thousands to tens of thousands of revolutions per minute, powerfully crushing and blending ingredients; if equipped with a heating function, the processing chamber can also generate high-temperature steam and boiling liquid. Significant safety risks are inherent in the operation of such equipment: when the lid is open, the device remains powered on. This can lead to the exposure of the high-speed rotating blades or the splashing of high-temperature liquid / steam, ultimately causing injury to the user or more dangerous consequences.

[0003] To prevent the aforementioned dangers, the blender must be designed so that it can only be powered on and start operating when the lid (top cover) is correctly, fully closed, and locked to the cup. For example, a blender disclosed in patent document CN207575055U provides a magnetic power-on / off device. This device uses magnets on the cup and top cover, along with a microswitch, to safely switch the blender on and off, ensuring that the blender can only operate after the top cover and cup are assembled.

[0004] However, when the food processor is working, the steam produced can escape from the gap between the lid and the body, forming condensation upon cooling. This condensation, under gravity, may seep back into the machine through these gaps. Since the microswitch is located near the lid, there is a risk that the condensation could come into contact with it, causing a short circuit in the overall circuitry. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a magnetic micro-switch structure with a two-stage push rod and waterproof, as well as a food processor. This can improve the waterproof performance of the internal circuit of food processor-type electrical equipment and ensure the safety of food processor use, so that the food processor can only be powered on and work when the top cover is closed and the inner cavity is sealed.

[0006] This utility model is implemented as follows:

[0007] A waterproof magnetic micro-switch structure with a two-stage push rod is installed inside a food processing appliance; the food processing appliance includes a body and a top cover, the body has a hollow handle, and the body has a processing cavity and an electrical unit; the top cover is connected to the body to seal the processing cavity;

[0008] It includes a micro switch, a first magnet, a second magnet, a first guide rod, and a second guide rod; the first magnet is fixedly mounted on the upper cover; the micro switch is located inside the machine body and is electrically connected to the power supply unit;

[0009] Both the first guide rod and the second guide rod are located inside the handle; the lower end of the first guide rod is a transmission end with an inclined surface, and the top of the upper end is fixedly provided with the second magnet; one end of the second guide rod is provided with a horizontally extending top rod, and the other end is a reversing end with an inclined surface; the transmission end and the reversing end abut at the two inclined surfaces; the first magnet is located directly above the second magnet and has the same polarity;

[0010] The lower end of the body and the handle are connected by a flexible waterproof cover, and the micro switch and the push rod are separated at both ends of the flexible waterproof cover; a return spring is provided on the first guide rod and / or the second guide rod.

[0011] After the top cover and the body are assembled, the two magnets approach each other. Under the action of magnetism, the repulsive force formed between the magnets drives the first guide rod to extend downward. Through the contact and movable cooperation of the two inclined surfaces, the direction of the repulsive force is changed from vertical to horizontal, which in turn pushes the top rod towards the flexible waterproof cover and the micro switch, causing the micro switch to open.

[0012] After the top cover separates from the body, the repulsive force disappears, and each component returns to its original position under the action of the return spring. At least one return spring is included.

[0013] The flexible waterproof cover serves to isolate liquid flow and prevent water penetration. Under the action of the push rod, the flexible waterproof cover deforms; furthermore, the flexible waterproof cover is made of elastic materials such as silicone and rubber. Under external force, it undergoes elastic deformation; when the external force is released, the flexible waterproof cover returns to its original state.

[0014] In this invention, the microswitch is located at the bottom of the machine body, away from steam and condensate. Combined with a waterproof cover, the risks of moisture and short circuits are greatly reduced. Through the top cover, magnet, microswitch, and transmission structure, it is ensured that power can only be supplied and the machine can only operate after the top cover and the machine body are connected, avoiding the risks of working in an exposed processing cavity.

[0015] As a further optimization of the above scheme, the transmission end has a first inclined surface that slopes inward and downward; the reversing end has a second inclined surface that slopes outward and upward; the first and second inclined surfaces have the same inclination angle.

[0016] The inner lower side satisfies the condition of facing both diagonally downwards and towards the inner side of the body; similarly, the outer upper side satisfies the condition of facing both diagonally upwards and towards the outer side of the body.

[0017] Furthermore, the extension length of the second inclined plane is longer than the extension length of the first inclined plane; or the extension length of the first inclined plane is longer than the extension length of the second inclined plane.

[0018] As a further optimization of the above solution, the end surface of the transmission end protrudes to form a pin, and the first inclined surface is located on the top surface of the pin; the end surface of the reversing end is recessed to form a groove, and the second inclined surface is located on the bottom surface of the groove; the pin is movably engaged with the groove.

[0019] Alternatively, the positions of the pin and the slide can be interchanged.

[0020] The use of pins and grooves creates a more stable and accurate force transmission and force reversal.

[0021] As a further optimization of the above solution, the first guide rod protrudes along its outer periphery to form a first limiting part; the handle is provided with a protruding second limiting part along its inner wall;

[0022] The reset spring includes a first spring and a second spring; the first spring is sleeved on the outer periphery of the first guide rod; the second spring and the second guide rod are assembled.

[0023] The radial dimension of the first limiting part is greater than the radial dimension of the first spring, and the first spring is located below the first limiting part; the first spring is limited between the first limiting part and the second limiting part, and all three are located within the vertical section of the handle.

[0024] The first spring is confined within the first and second limiting portions; when the first guide rod moves downward, the spring is compressed. The second spring is used to reset the second guide rod.

[0025] As a further optimization of the above solution, there are multiple second limiting parts, which are evenly distributed along the vertical segment; the first spring is located between the first limiting part and one of the second limiting parts;

[0026] The second limiting part is disposed around the outer periphery of the first guide rod.

[0027] The vertical section refers to the part of the handle that extends vertically. Generally, handles are usually C-shaped or arch-shaped, with the middle section typically extending vertically.

[0028] The second limiting part is used to cooperate with the first limiting part to compress the spring, and also to limit the movement of the first guide rod, so that the first guide rod can only move up and down in the vertical direction.

[0029] As a further optimization of the above solution, a limiting plate is fixedly provided inside the handle, and the limiting plate is located on one side of the flexible waterproof cover; the surface of the limiting plate is provided with a through hole, and a protrusion is formed around the periphery of the through hole to form a guide channel; the top rod is movably engaged with the guide channel.

[0030] By setting up guide channels, the second guide rod can be restricted to moving laterally only via the top rod.

[0031] As a further optimization of the above solution, the first guide rod extends along the inner cavity of the handle to the bottom of the handle; in the second guide rod, the reversing end is formed at the end of the top rod extending in the opposite direction.

[0032] On the second guide rod, the radial dimension of the reversing end is greater than the radial dimension of the top rod; the second spring is sleeved on the outer periphery of the top rod and located between the limiting plate and the reversing end; the radial dimension of the second spring is smaller than that of the reversing end.

[0033] Under the action of repulsive force, the push rod extends and moves inward toward the micro switch, and the second spring is compressed.

[0034] As a further optimization of the above solution, both the first guide rod and the second guide rod extend along the inner cavity of the handle, and the two meet at the vertical section of the inner cavity of the handle;

[0035] The second guide rod is L-shaped, with the lower part of the second guide rod being the top rod and the upper end of the second guide rod forming the reversing end;

[0036] There are two or more second springs, all located within the vertical section of the handle; one end of the second spring faces the inner side of the machine body and is fixedly connected to the inner wall of the handle, while the other end faces the second guide rod.

[0037] Furthermore, the inner wall of the handle is provided with a limiting groove in the vertical section; the limiting groove matches the end of the second spring, and the two correspond one-to-one.

[0038] There is more than one second spring to prevent the elastic force of the second spring acting on the second guide rod from concentrating at one point and to prevent the second guide rod from only rotating and deviating under the action of force; two or more second springs ensure the lateral reset of the second guide rod.

[0039] As a further optimization of the above solution, one or more drainage holes are provided at the bottom of the handle.

[0040] Even if water gets inside the handle cavity, it can be drained through the drainage holes without penetrating the microswitch and its associated circuitry.

[0041] This utility model also provides a food processor, including a body and a top cover. The body has a hollow handle, and the body has a mixing cup and an electrical unit. The inner cavity of the mixing cup is the processing chamber. The top cover is connected to the body to seal the processing chamber.

[0042] The power unit includes a drive module and a heating module; the heating module is attached to the outer bottom of the stirring cup; the drive module is equipped with a drive shaft that extends upward through the stirring cup, and the upper end of the drive shaft is connected to a stirring assembly, which is located inside the processing cavity;

[0043] This food processor uses a magnetic micro-switch structure with a two-stage push rod and waterproof design, as described above.

[0044] The beneficial effects are as follows:

[0045] This invention provides a waterproof magnetic micro-switch structure with a two-stage push rod and a food processor. When the top cover and body are closed, the magnetic repulsion drives the guide rod mechanism. A sloping structure converts vertical displacement into lateral displacement, triggering the micro-switch at the bottom, ultimately controlling the circuit of the food processor or similar device. This structure keeps the micro-switch away from steam and condensation areas, and combined with the sealing of the flexible waterproof cover, significantly reduces the risk of short circuits due to moisture in the internal circuitry. The magnetic drive mechanism ensures that the device only operates when the top cover is fully closed, effectively eliminating potential hazards when the processing chamber is exposed. A return spring system ensures that all components quickly return to their original positions. The overall structure combines mechanical reliability with equipment safety and waterproofing.

[0073] 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.

[0074] Example 1

[0075] like Figures 1 to 9 As shown, this embodiment provides a food processor, including a body 1 and a top cover 2. The body 1 has a hollow handle 3 on its outside and a mixing cup 4 and an electrical unit inside the body 1. The inner cavity of the mixing cup 4 is a processing chamber 4-1. The top cover 2 is connected to the body 1 to seal the processing chamber 4-1.

[0076] The power supply unit includes a drive module 5 and a heating module 6. The heating module 6 is attached to the outer bottom of the stirring cup 4. The drive module 5 is equipped with a drive shaft 5-1 that extends upward through the stirring cup 4. The upper end of the drive shaft 5-1 is connected to a stirring assembly 7, which is located inside the processing chamber 4-1. The drive module 5 is specifically a motor. The heating module 6 consists of a heating tube and a heat-conducting plate. The stirring assembly 7 consists of a stirring blade and its shaft.

[0077] The food processor also uses a magnetic micro switch 14 structure with a two-stage push rod and waterproof design. Specifically, it includes a micro switch 14, a first magnet 2-1, a second magnet 8-1, a first guide rod 8, and a second guide rod 9. The first magnet 2-1 is fixedly mounted on the top cover 2. The micro switch 14 is located at the bottom of the body 1 and is electrically connected to the power unit.

[0078] The first guide rod 8 and the second guide rod 9 are both located inside the handle 3.

[0079] Specifically, the first guide rod 8 extends along the inner cavity of the handle 3 to the bottom of the handle 3; a second magnet 8-1 is fixedly mounted on the top of the upper end of the first guide rod 8. After the body 1 and the upper cover 2 are combined, the first magnet 2-1 is located directly above the second magnet 8-1, and they have the same polarity. The lower end of the first guide rod 8 is the transmission end 8-2. In this embodiment, the end surface of the transmission end 8-2 protrudes to form a pin 8-3, and the end surface of the pin 8-3 is formed as a first inclined surface 8-4, which faces inward and downward.

[0080] In this embodiment, the second guide rod 9 includes a laterally extending top rod 9-1, which faces the micro switch 14 inside the body 1. The end extending in the opposite direction along the top rod 9-1 is a reversing end 9-2. The end surface of the reversing end 9-2 is recessed to form a groove 9-3. The bottom surface of the groove 9-3 is a second inclined surface 9-4, which faces the upper outer side.

[0081] The first inclined plane 8-4 and the second inclined plane 9-4 have the same inclination angle. The inner lower side satisfies the condition of facing both diagonally downward and towards the inside of the body 1; the outer upper side satisfies the condition of facing both diagonally upward and towards the outside of the body 1.

[0082] The pin 8-3 and the slide groove 9-3 are in a movable fit. This movable fit means that the pin 8-3 can slide along the slide groove 9-3. The first guide rod 8 abuts against the slide groove 9-3 of the second guide rod 9 via the pin 8-3.

[0083] In this embodiment, the first guide rod 8 protrudes along its outer periphery to form a first limiting part 8-5; the handle 3 has a second limiting part 3-1 protruding along its inner wall. There are multiple second limiting parts 3-1, which are evenly distributed along the vertical section of the handle 3; after assembly, the second limiting parts 3-1 surround the outer periphery of the first guide rod 8. The vertical section refers to the part of the handle 3 that extends vertically.

[0084] A first spring 10 is sleeved on the outer periphery of the first guide rod 8; the radial dimension of the first limiting part 8-5 is larger than the radial dimension of the first spring 10, and the first spring 10 is located below the first limiting part 8-5. The first spring 10 is limited between the first limiting part 8-5 and a second limiting part 3-1, and all three are located within the vertical section of the handle 3.

[0085] The second limiting part 3-1 is used to cooperate with the first limiting part 8-5 to compress the spring, and also to limit the movement of the first guide rod 8, so that the first guide rod 8 can only move up and down in the vertical direction.

[0086] In this embodiment, a limiting plate 12 is fixedly installed inside the handle 3, and the limiting plate 12 is located on one side of the flexible waterproof cover 13; the surface of the limiting plate 12 has a through-hole, and a protrusion is formed around the periphery of the through-hole to form a guide channel 12-1. The top rod 9-1 is movably engaged with the guide channel 12-1. By setting the guide channel 12-1, the second guide rod 9 can be restricted to moving laterally only through the top rod 9-1.

[0087] On the second guide rod 9, the radial dimension of the reversing end 9-2 is larger than the radial dimension of the push rod 9-1; a second spring 11 is sleeved on the outer periphery of the push rod 9-1, and the second spring 11 is located between the limiting plate 12 and the reversing end 9-2; the radial dimension of the second spring 11 is smaller than that of the reversing end 9-2. Under the action of repulsive force, the push rod 9-1 extends and moves inward toward the micro switch 14, and the second spring 11 is compressed.

[0088] The first spring 10 and the second spring 11 are both return springs, used to reset the first guide rod 8 and the second guide rod 9, respectively.

[0089] A flexible waterproof cover 13 is provided at the lower end of the body 1 and the handle 3. The micro switch 14 and the top rod 9-1 are separated at both ends of the flexible waterproof cover 13.

[0090] In this embodiment, the bottom of the handle 3 is provided with multiple drainage holes 3-2. Even if water enters the inner cavity of the handle 3, it can be drained through the drainage holes 3-2 without penetrating into the micro switch 14 and its associated circuitry.

[0091] After the top cover 2 and the body 1 are assembled, the two magnets approach each other. Under the action of magnetism, the repulsive force formed between the magnets drives the first guide rod 8 to extend downward. Through the contact and movable cooperation of the two inclined surfaces, the direction of the repulsive force is changed from vertical to horizontal, thereby pushing the top rod 9-1 towards the flexible waterproof cover 13 and the micro switch 14, so that the micro switch 14 is turned on.

[0092] After the top cover 2 and the body 1 separate, the repulsive force disappears, and each component resets under the action of the reset spring.

[0093] The flexible waterproof cover 13 serves to isolate liquid flow and prevent water penetration. Under the action of the top rod 9-1, the flexible waterproof cover 13 deforms.

[0094] In this embodiment, the micro switch 14 is located at the bottom of the machine body 1, away from steam and its condensate. Combined with the waterproof cover, the risks of moisture and short circuits are greatly reduced. Through the upper cover 2, the magnet, the micro switch 14, and the transmission structure, it is ensured that the machine can only be powered on and operate after the upper cover 2 and the machine body 1 are connected, avoiding the risks of working under the exposed processing cavity 4-1.

[0095] Example 2

[0096] This implementation example Figures 10 to 12 As shown, features not explained in this embodiment are explained using the method described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0097] The first guide rod 8 and the second guide rod 9 both extend along the inner cavity of the handle 3, and they meet in the vertical section of the inner cavity of the handle 3.

[0098] The second guide rod 9 is L-shaped, with the lower part of the second guide rod 9 being the top rod 9-1 and the upper end of the second guide rod 9 forming the reversing end 9-2;

[0099] There are two second springs 11, both located in the vertical section of the handle 3; one end of the second spring 11 faces the inside of the body 1 and is fixedly connected to the inner wall of the handle 3, and the other end faces the second guide rod 9.

[0100] In this embodiment, the first guide rod 8 does not cooperate with the first spring 10. The second guide rod 8 is indirectly reset by the second spring 11 through the second guide rod 9. That is, the first guide rod 8 is reset by the second inclined surface 9-4 and the first inclined surface 8-4 pushing the first guide rod 8 in the opposite direction.

[0101] When the top cover 2 and the body 1 are assembled, the two magnets approach each other and generate a repulsive force, which drives the first guide rod 8 to move vertically downward. The first guide rod 8 transmits the force to the second guide rod 9 through the first inclined surface 8-4 and the second inclined surface 9-4. In conjunction with the guide channel 12-1, the second guide rod 9 moves laterally inward. At this time, the second guide rod 9 compresses the two second springs 11, and the top rod 9-1 triggers the micro switch 14.

[0102] After the top cover 2 and the body 1 separate, the repulsive force disappears, and the second guide rod 9 returns to its original position under the elastic action of the second spring 11.

[0103] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. 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.
