A meat grinder main unit and meat grinder

Abstract

This utility model discloses a meat grinder main unit and a meat grinder. The main unit includes a motor, a push-button switch, a first magnetic chuck, and a button. The push-button switch is movably configured, and the first magnetic chuck is located on the push-button switch. The button is used to apply pressure to the push-button switch. When the push-button switch moves to a target position due to the repulsive force of the first magnetic chuck, the push-button switch can be electrically connected to the motor under the pressure of the button. When the first magnetic chuck is not subjected to the repulsive force, the push-button switch is in a non-target position. Whether the push-button switch is subjected to pressure or not, the push-button switch and the motor cannot be electrically connected. This utility model achieves electrical connection between the push-button switch and the motor in a specific position through magnetic repulsive force. When not properly assembled, the first magnetic chuck lacks the repulsive force, causing the push-button switch to be in a non-target position. Even if the button is pressed, the motor cannot be connected, fundamentally avoiding the risk of injury to the user caused by starting the meat grinder if it is not properly installed.

[0011] Furthermore, the push-button switch has at least a vertical degree of freedom of movement, the button is located above the push-button switch, and the push-button switch is closer to the button when it is in the target position compared to when it is in a non-target position.

[0013] Furthermore, the push button switch also includes a switch housing, and both the upper and lower contacts of the switch are disposed within the switch housing. The upper contact of the switch is movably disposed relative to the switch housing, and the lower contact of the switch is fixedly disposed relative to the switch housing.

[0014] Furthermore, the push button switch also includes a switch pressing handle, which is connected to the contacts on the switch. When the switch pressing handle is pressed by the button, the switch pressing handle drives the contacts on the switch to move.

[0015] Furthermore, the switch push handle is elastically connected to the contacts on the switch.

[0020] The beneficial effects of this utility model compared with the prior art are as follows: This utility model provides a meat grinder main unit, including a motor, a push-button switch, a first magnetic chuck, and a button. The push-button switch is movably configured, the first magnetic chuck is disposed on the push-button switch, and the button is used to apply pressure to the push-button switch. When the push-button switch moves to the target position due to the repulsive force of the first magnetic chuck, the push-button switch can be electrically connected to the motor under the pressure of the button. When the first magnetic chuck is not subjected to the repulsive force, the push-button switch is in a non-target position. Whether the push-button switch is subjected to pressure from the button or not, neither the push-button switch nor the motor can be electrically connected. This utility model achieves electrical connection between the push-button switch and the motor in a specific position through magnetic repulsive force. When not properly assembled, the first magnetic chuck lacks the repulsive force, causing the push-button switch to be in a non-target position. Even if the button is pressed, the motor cannot be connected, fundamentally avoiding the risk of injury to the user caused by starting the meat grinder if it is not properly installed, and greatly improving the safety of product use.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0035] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] like Figures 1 to 5 As shown, a meat grinder includes a grinding blade 1, a bowl body 2, a bowl lid 3, and a main body 4. The bowl body 2 is made of transparent glass with an opening at the top to hold the ingredients to be ground. The bowl lid 3 is tightly fitted onto the bowl body 2 via a snap-fit ​​or screw-on method to prevent ingredients from splashing out during grinding. The bottom of the main body 4 has a protruding structure that matches the shape of the mounting opening 31 of the bowl lid 3. It is secured to the bowl lid 3 via a snap-fit ​​mechanism, thus mounting the main body 4 onto the bowl lid 3.

[0037] The main body 4 of the meat grinder includes a main body housing 45, and a motor 44, a push-button switch 41, a first magnetic chuck 42, and a button 43 mounted on the main body housing 45. The push-button switch 41 is movably mounted on the top of the main body housing 45, the first magnetic chuck 42 is mounted on the push-button switch 41, and the button 43 is used to apply pressure to the push-button switch 41. The first magnetic chuck 42 can be a ferrite magnet or a neodymium iron boron magnet. The meat grinder blade 1 is made of stainless steel, has a spiral cross shape, and is located at the center of the bowl body 2. Its upper end is connected to the output shaft of the motor 44 via a spline, so that the rotational power of the motor 44 can be effectively transmitted to the meat grinder blade 1.

[0038] When the first magnetic attractor 42 is subjected to a repulsive force, causing the push button switch 41 to move to the target position, the push button switch 41 can be electrically connected to the motor 44 under the pressure of the button 43; when the first magnetic attractor 42 is not subjected to a repulsive force, the push button switch 41 is in a non-target position; when the push button switch 41 is subjected to or not subjected to the pressure of the button 43, neither the push button switch 41 nor the motor 44 can be electrically connected.

[0039] Specifically, the first magnetic suction element 42 is the core component controlling whether the push-button switch 41 and the motor 44 can conduct electricity. When the meat grinder main unit 4 is correctly installed on the bowl cover 3, under the repulsive force of the first magnetic suction element 42, the push-button switch 41 will move upward to the target position. At this time, the internal structure of the push-button switch 41 is in a conductive state. When the user presses the button 43, the button 43 applies pressure to the push-button switch 41. This pressure can cause the conductive components inside the push-button switch 41 to make contact with each other, thereby realizing the electrical conduction between the push-button switch 41 and the motor 44. After the motor 44 is powered on, it drives the meat grinder blade 1 to work.

[0040] When the main body 4 of the meat grinder is not correctly installed on the lid 3, the first magnetic suction element 42 cannot be subjected to repulsive force, and the push-button switch 41 will be in the non-target position. In this state, regardless of whether the user presses the button 43 or applies pressure to the push-button switch 41, the conductive parts inside the push-button switch 41 cannot make contact, and therefore cannot achieve electrical conduction with the motor 44, and the motor 44 will not start.

[0041] The magnetic attraction force enables the button switch 41 to be electrically connected to the motor 44 at a specific position. When not properly assembled, the first magnetic attraction component 42 lacks the repulsive force, causing the button switch 41 to be in a non-target position. Even if the button 43 is pressed, the motor 44 cannot be connected. This fundamentally avoids the risk of injury to the user caused by the meat grinder starting up if it is not installed correctly, and greatly improves the safety of the product.

[0042] It should be noted that the repulsive force on the first magnetic attractor 42 may come from another magnetic attractor with the same polarity, or from a metal conductor that can generate electromagnetic induced current. That is, when the first magnetic attractor 42 is close to the metal conductor, the magnetic field generated by the induced current of the metal conductor will repel the magnetic field of the first magnetic attractor 42.

[0043] It should also be noted that the aforementioned target position refers to the position where the push-button switch 41, after being subjected to a specific force such as magnetic repulsion, moves to a position where it can respond to the pressing pressure of the button 43 and achieve circuit connection. In this position, the structural components of the push-button switch 41 are in a preparatory, conductive state; only the pressing pressure of the button 43 is required to complete the circuit connection. Understandably, when the first magnetic member 42 is subjected to a repulsive force, the repulsive force will push the push-button switch 41 to move in a specific direction (such as upwards) to reach the "target position." In the target position, the two conductive contact parts of the push-button switch 41 are in a "close but not contacting" state. At this time, the push-button switch 41 is ready to conduct; only the pressing pressure of the button 43 is required to make the two conductive contact parts contact, thus completing the circuit connection.

[0044] The aforementioned non-target position refers to the position of the push-button switch 41 when it is not subjected to effective repulsive force. In this position, the two conductive contact parts of the push-button switch 41 cannot respond to the pressing force of the button 43, and even if the button 43 is pressed, the circuit cannot be connected. Understandably, since the button 43 has a certain travel distance, in the non-target position, the distance between the button 43 and the two conductive contact parts of the push-button switch 41 is too far. Even if the button 43 is pressed and reaches its maximum travel, the two conductive contact parts of the push-button switch 41 cannot make contact, so the circuit cannot be connected.

[0045] The aforementioned electrical conduction refers to the two conductive contact parts inside the push-button switch 41 coming into contact with each other after being pressed, forming a complete current path, enabling the motor 44 to be energized and run. Conversely, if the two conductive contact parts do not make contact, the current path is broken, and the motor 44 cannot start.

[0046] Furthermore, the push-button switch 41 has at least vertical freedom of movement, and the button 43 is positioned above the push-button switch 41. When the push-button switch 41 is in the target position, it is closer to the button 43 than when it is in a non-target position. This design is because the button 43 has a fixed travel distance. In the target position, the distance between the push-button switch 41 and the button 43 is shorter, thus satisfying the fixed travel characteristic of the button 43. This allows the two conductive contacts inside the push-button switch 41 to make contact within the fixed travel range. In the non-target position, the distance between the push-button switch 41 and the button 43 is greater, preventing the two conductive contacts inside the push-button switch 41 from making contact within the fixed travel range. By varying the distance between the push-button switch 41 and the button 43 in different states, combined with the fixed travel characteristic of the button 43, the physical structure mandates that the button 43 can only trigger the circuit to conduct when the meat grinder main unit 4 is correctly installed (the push-button switch 41 is in the target position). If not installed correctly, pressing button 43 will not start motor 44, effectively avoiding the safety hazard of starting the meat grinder before it is properly installed due to misoperation. Furthermore, users do not need to additionally check whether the meat grinder is installed correctly; they can intuitively perceive the installation status simply by whether button 43 can normally trigger motor 44. If the meat grinder does not respond after pressing button 43, the user can immediately realize that the equipment is not installed correctly, reducing operational complexity and the risk of misjudgment.

[0047] In one embodiment, to allow the push-button switch 41 to have freedom of movement in the vertical direction, the main housing 45 has an internal receiving cavity containing a substrate. The push-button switch 41 is connected to the substrate via a guide structure, thereby allowing the push-button switch 41 to move freely only in the vertical direction. The button 43 can be a circular silicone button 43, embedded in the top of the main housing.

[0048] For example, the guide structure includes a guide groove 4111 and a guide block. The push button switch 41 is provided with the guide groove 4111 and the substrate is provided with the guide block. Through the cooperation of the guide groove 4111 and the guide block, the push button switch 41 and the substrate are connected to each other. That is, when the first magnetic attractor 42 is subjected to a repulsive force, the push button switch 41 can move upward in the vertical direction.

[0049] like Figure 3As shown, the push-button switch 41 includes an upper contact 412 and a lower contact 413 (i.e., the two conductive contact components mentioned above). The upper contact 412 and the lower contact 413 are movably disposed relative to each other. When the upper contact 412 or the lower contact 413 is pressed by the button 43, the upper contact 412 and the lower contact 413 move closer to each other. When the upper contact 412 and the lower contact 413 are in contact, the push-button switch 41 is electrically connected to the motor 44.

[0050] Both the upper contact 412 and the lower contact 413 of the switch are movable structures, or one of the upper contact 412 and the lower contact 413 of the switch is a movable structure and the other is a non-movable structure.

[0051] By adjusting the relative movement of the upper contact 412 and the lower contact 413 of the switch, and combining the pressure of the button 43 to achieve contact contact and separation, the power supply to the motor 44 can be precisely controlled, ensuring that the meat grinder starts and stops stably under user operation, and avoiding circuit mis-triggers or poor contact problems.

[0052] like Figure 3 As shown, the push button switch 41 also includes a switch housing 411. The upper contact 412 and the lower contact 413 are both located inside the switch housing 411. The upper contact 412 is movably disposed relative to the switch housing 411, and the lower contact 413 is fixedly disposed relative to the switch housing 411.

[0053] In one embodiment, the lower contact 413 of the switch is made of a conductive metal sheet and can be fixed to the circuit board of the switch housing 411 by welding. The circuit board is wired to the motor 44. The surface of the lower contact 413 is plated with a silver layer to reduce contact resistance. The upper contact 412 of the switch is also made of a conductive metal sheet and is slidably connected to the switch housing 411 by two vertical metal guide posts. When the push-button switch 41 is in the target position and the user presses the button 43, the upper contact 412 moves downward until it contacts the lower contact 413, forming a complete current path, thereby energizing the motor 44 to run.

[0054] By designing the upper contact 412 of the switch to be movable relative to the housing and the lower contact 413 of the switch to be fixed, it is ensured that the contacts can be accurately aligned and contacted when the button 43 is pressed, reducing contact resistance, ensuring stable conduction of the motor 44 circuit, and avoiding equipment failure due to poor contact.

[0055] like Figure 3As shown, the push-button switch 41 also includes a switch pressing handle 414, which is connected to the upper contact 412 of the switch. When the switch pressing handle 414 is pressed by the button 43, it drives the upper contact 412 of the switch to move. Through the connection design of the switch pressing handle 414, it is ensured that the pressing force of the button 43 can be accurately and stably transmitted to the upper contact 412 of the switch, avoiding force loss or deviation, ensuring reliable contact of the contacts, and realizing stable conduction and disconnection of the motor 44 circuit.

[0056] like Figure 3 As shown, the switch pressing handle 414 is elastically connected to the upper contact 412 of the switch. Specifically, the switch pressing handle 414 includes a pressing part 4141 and an elastic part 4142. The upper end of the elastic part 4142 is connected to the pressing part 4141, and the lower end of the elastic part 4142 is connected to the upper contact 412 of the switch.

[0057] In one embodiment, the pressing part 4141 is made of hard plastic and has a bent rod-like structure with anti-slip texture on the surface for easy application of force by the user. The elastic part 4142 is a cylindrical helical spring. The upper end of the helical spring is fixed to the center of the bottom surface of the pressing part 4141, and the lower end is slidably connected to a metal guide post of the switch housing 411. When the user presses the pressing part 4141, the helical spring is compressed and contracts, transmitting the pressing force through the metal guide post to the upper contact 412 of the switch, causing it to move downward and contact the fixed lower contact 413 of the switch, thus completing the circuit. After the pressing part 4141 is released, the helical spring returns to its original shape, causing the upper contact 412 of the switch to reset.

[0058] like Figure 2 As shown, the first magnetic attractor 42 is provided on the switch housing 411, and the cup cover 3 is provided with the second magnetic attractor 5. The second magnetic attractor 5 can be a ferrite magnet or a neodymium iron boron magnet. The second magnetic attractor 5 and the first magnetic attractor 42 repel each other, that is, the second magnetic attractor 5 and the first magnetic attractor 42 have the same polarity.

[0059] In one embodiment, the first magnetic suction member 42 is specifically installed at the bottom of the switch housing 411, and the second magnetic suction member 5 is specifically installed at the mounting opening 31 near the bowl cover 3. This design ensures that after the meat grinder main unit 4 is correctly installed, the positions of the first magnetic suction member 42 and the second magnetic suction member 5 are relatively close, which is conducive to generating a repulsive force between the first magnetic suction member 42 and the second magnetic suction member 5.

[0060] One or more first magnetic attractors 42 can be provided, and the second magnetic attractor 5 has the same size as the first magnetic attractor 42 and is provided in a corresponding manner to the first magnetic attractor 42.

[0061] When the main body 4 of the meat grinder is installed on the lid 3, the first magnetic component 42 and the second magnetic component 5 approach each other. The repulsive force generated by the repulsion of like poles pushes the push-button switch 41 upward, so that the push-button switch 41 reaches the target position. At this time, when the user presses the button 43, the upper contact 412 and the lower contact 413 inside the push-button switch 41 can make smooth contact, realizing the circuit of the motor 44.

[0062] The mutual repulsion between the first magnetic element 42 and the second magnetic element 5 enables automatic control of the position of the button switch 41, ensuring that the button switch 41 can only be in the target position for conducting the circuit when the main unit of the meat grinder is correctly installed on the bowl cover 3. This effectively prevents the motor 44 from starting when it is not properly installed, ensuring user safety.

[0063] The working principle is as follows:

[0064] When the main body 4 of the meat grinder is correctly installed on the bowl lid 3 through the mounting port 31, the second magnetic suction member 5 on the bowl lid 3 and the first magnetic suction member 42 on the push button switch 41 are aligned vertically. Since their opposing surfaces are of the same polarity, a repulsive force is generated according to the principle of "like poles repel". This repulsive force will push the push button switch 41 upward to the target position. When the push button switch 41 is in the target position, the distance between the upper contact 412 and the lower contact 413 in the push button switch 41 is shortened to a suitable range. When the user presses the button 43, the button 43 transmits the pressing force to the upper contact 412 through the switch pressing handle 414. Under the action of the pressing force, the upper contact 412 overcomes the elastic force of the elastic part 4142 and continues to move downward until it contacts the lower contact 413, thus forming a complete current path. At this time, the power supply is connected to the motor 44 through the push button switch 41. The motor 44 is powered on and started, driving the meat grinder blade 1, which is connected to the output shaft, to rotate at high speed in the bowl 2, performing the grinding work on the ingredients in the bowl 2.

[0065] If the main unit 4 of the meat grinder is not correctly installed on the lid 3, the first magnetic suction member 42 will not receive sufficient repulsive force from the second magnetic suction member 5. Under its own weight, the push-button switch 41 will be in a non-target position (usually a low position). When the push-button switch 41 is in a non-target position, the distance between the upper contact 412 and the lower contact 413 is greater than the distance required for them to make contact. Even if the user presses the button 43, the button 43 will cause the upper contact 412 to press down via the switch pressing handle 414. However, because the initial position of the upper contact 412 is too low, the downward movement distance is insufficient for it to make contact with the lower contact 413. Therefore, the push-button switch 41 cannot form a current path, the power cannot be connected to the motor 44, and the motor 44 will not start. This design avoids injury to the user due to loose parts or food splashing when the meat grinder is not properly installed, ensuring user safety.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
