The meat grinder controls the motor to start and stop through a microswitch, and the operating speed of the meat grinder is fixed, and the food crushing degree obtained by the user is also fixed. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a two-gear meat grinder, aiming to solve the problem that various food crushing degrees cannot be obtained.
[0005] To achieve the above purpose, according to the first aspect of the present application, the present application provides a two-gear meat grinder, including:
[0006] A stirring assembly, which is driven by a motor and is used for stirring food;
[0007] A switch assembly, which includes a push rod, a first microswitch, and a second microswitch;
[0008] The push rod can move along a first direction towards a second position or along a second direction towards a first position, and the first direction and the second direction are opposite;
[0009] The first microswitch includes a first contact, and the second microswitch includes a second contact; the first and second contacts are located between the first position and the second position; and the first and second microswitches are electrically connected to the motor;
[0010] Wherein, when the push rod moves along the first direction, the push rod can press the first contact and the second contact in sequence.
[0011] Compared with the prior art, when the push rod of the two-gear meat grinder according to the embodiment of the present application moves along the first direction, the first and second contacts are located between the first position and the second position, so that the push rod can press the first contact of the first microswitch and the second contact of the second microswitch in sequence, so that the motor electrically connected to the microswitch can obtain different electrical signals, and thus the motor outputs different speeds to stir food, and the user can control and select different gears through the push rod to achieve different food crushing degrees.
[0012] In some embodiments, the switch assembly further includes a switch button, one end of which is connected to the ejector rod. When the switch button is subjected to an external force, it can apply a force in the first direction to the ejector rod, so that the ejector rod moves towards the second position.
[0013] By providing the switch button, it is possible for the ejector rod to move towards the second position.
[0014] In some embodiments, the first microswitch includes a first plane, and the first contact is disposed on the first plane;
[0015] The second microswitch includes a second plane, and the second contact is disposed on the second plane;
[0016] Wherein, the first plane and the second plane are oppositely disposed and inclined at an angle to each other, so that when the ejector rod moves in the first direction, the vertical distances between the ejector rod and the first plane and the second plane become smaller;
[0017] When the ejector rod presses the first and second contacts, the first contact and the second contact can rely on their own elastic forces to provide a force for the ejector rod to move towards the second position.
[0018] By providing the first plane and the second plane, the first plane and the second plane are oppositely disposed and inclined at an angle to each other. When the ejector rod moves in the first direction, the distances between the ejector rod and the first plane and the second plane become smaller, that is, the included angle formed by the first plane and the second plane faces the first position. When the first and second contacts are pressed, due to the elasticity of the contacts themselves, a force for the ejector rod to move partially in the second direction can be provided, so that the first contact and the second contact located on the first plane and the second plane can rely on their own elastic forces to provide a force for the ejector rod to move in the second direction, so that the ejector rod can move towards the second position, that is, the ejector rod can automatically reset to the first position.
[0019] In some embodiments, the two-speed meat grinder further includes: a body, and the body includes an ejector rod limiting groove for partially accommodating the ejector rod, so that the ejector rod moves between the first position and the second position in the limiting groove.
[0020] By providing the ejector rod limiting groove, the ejector rod can move between the first position and the second position in the ejector rod limiting groove.
[0021] In some embodiments, one end of the ejector rod includes a chamfer or a fillet, so that when the ejector rod moves, the chamfer or the fillet can press the first and second contacts.
[0022] By providing a chamfer or a fillet at one end of the ejector rod, when the ejector rod moves in the first direction, the movement stroke of the ejector rod is converted into the movement stroke of the first and second contacts through the inclined surface of the chamfer or the curved surface of the fillet, so that the first and second contacts can be pressed.
[0023] In some embodiments, the switch assembly includes a microswitch base, and the first and second microswitches are fixed to the microswitch base.
[0024] By providing a microswitch base and fixing the microswitches thereto, the microswitches are not likely to slip or become loose when pressed by the ejector rod, further improving the stability of the device.
[0025] In some embodiments, the microswitch base is capable of moving between a third position and a fourth position;
[0026] The microswitch base includes an elastic element, which is externally fixed. The elastic element can provide a force on the microswitch base in a third direction, enabling the microswitch base to move from the fourth position to the third position, where the third direction is the direction from the fourth position towards the third position;
[0027] Wherein,
[0028] When the ejector rod does not press the first and second contacts, the microswitch base is located at the third position;
[0029] When the ejector rod presses the second contact, the microswitch base is located at the fourth position.
[0030] By providing an elastic element in the microswitch base, when the ejector rod presses the first microswitch and continues to move in the first direction, the elastic element can provide an elastic force in the third direction to the switch button base, which is conducted to the ejector rod through the microswitch. The ejector rod will encounter resistance when continuing to move, thus reminding the user that the first microswitch gear has been turned on. When the ejector rod is not subject to external force, the elastic element can provide an elastic force in the third direction to the switch button base to help the ejector rod reset.
[0031] In some embodiments, the two-gear meat grinder further includes: a body, and the body includes a microswitch base limiting groove for partially accommodating the microswitch base, enabling the microswitch base to move between the third position and the fourth position within the limiting groove.
[0032] By providing the microswitch base limiting groove, it makes it possible for the microswitch base to move between the third position and the fourth position.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the embodiments of the present application.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
[0053] In addition, in the description of the present application, unless otherwise specified, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0054] The present application provides a two-speed meat grinder, which can select different gears by controlling the push rod to trigger the first contact and the second contact in sequence, so that the motor provides different speeds, providing multiple gear selections for the meat grinder. Specifically, the two-speed meat grinder can be used for crushing meat, stirring fruits, grinding beans, etc. When grinding relatively crispy fruits or grinding a small amount of food, a low gear can be selected, and the motor outputs a lower speed to save electricity; when crushing relatively viscous meat or grinding a large amount of food, a high gear can be selected, and the motor outputs a higher speed to achieve a better grinding effect. The following will elaborate on an embodiment of the two-speed meat grinder.
[0055] As Figure 1 shown, the two-speed meat grinder of the present application includes a stirring assembly 1 and a switch assembly 2.
[0056] As Figure 2As shown in the figure, the stirring assembly 1 is driven by a motor 11 to stir food. For example, the stirring assembly is driven by an asynchronous motor, a shaded-pole motor, etc. Preferably, a shaded-pole motor is selected to provide stability and low power consumption. The motor shaft 111 of the motor 11 can be directly connected to a blade (not shown in the figure); the motor shaft 111 can also be connected to a gear set 12, and the gear set 12 is connected to the blade. Through the transmission of the gear set 12, the low torque and high speed of the motor shaft 111 are converted into the high torque and low speed of the blade, or the speed of the blade is further increased and the torque of the blade is reduced through the gear set 12. The motor 11 can be directly installed on the blender body 3; or a motor base can be installed on the blender body 3, and the motor is installed on the motor base to play a role in shock absorption. The motor 21 has different speeds. For example, the switch assembly 2 is electrically connected to the motor 11, and the switch assembly 2 provides different electrical signals, and the motor 11 operates at different speeds.
[0057] As Figure 3 shown, the switch assembly 2 includes a push rod 21, a first microswitch 22, and a second microswitch 23.
[0058] The push rod 21 can move in the first direction towards the second position or in the second direction towards the first position, and the first direction and the second direction are opposite. For example, the push rod 21 can be directly pressed by the user to move; or the user presses an external button, and the button presses the push rod 21 to make the push rod 21 move. Specifically, in this embodiment, the first direction is the direction from top to bottom, and the second direction is the direction from bottom to top. In order to make the push rod 21 more compact with the meat grinder, the push rod 21 can be designed in an arc shape that fits the meat grinder body. At the weak part of the push rod 21 structure, reinforcing ribs can be provided to increase the strength of the push rod 21. The part of the push rod 21 that presses the microswitch is the lower end of the push rod, and its shape is cylindrical.
[0059] The first microswitch 22 includes a first contact 221, which is located between the first position and the second position. The second microswitch 23 includes a second contact 231. The first contact 221 and the second contact 231 are located between the first position and the second position. And the first and second microswitches are electrically connected to the motor 11. Specifically, the first microswitch 22 and the second microswitch 23 are arranged opposite to each other, and the longer sides of the microswitches are placed in the vertical direction; of course, the first and second microswitches can also be arranged vertically in sequence. The first and second microswitches can be directly installed on the body 3; or they can be installed on a fixed seat, and removing the fixed seat can realize the removal of all microswitches, making the installation and removal of the microswitches more convenient. The first contact 221 and the second contact 231 are located between the first position and the second position, that is, on the movement track of the push rod 21, so that when the push rod 21 moves, it can press the first microswitch 22 and the second microswitch 23.
[0060] When the first contact 221 is pressed, the motor can operate at the first rotational speed, i.e., the low gear of the low rotational speed; when the second contact 231 is pressed, the motor can operate at the second rotational speed, i.e., the high gear of the high rotational speed. The electrical connection between the first and second microswitches and the motor 11 can be in the form of a series resistor. For example, the motor is in series with a resistor, and this resistor is in parallel with the second microswitch 23. When the first contact 221 is pressed, the motor starts. When the second contact 231 is pressed, the series resistor is short-circuited, so that the power of the motor is increased and the rotational speed becomes faster. It should be understood that other electrical connection methods between the microswitch and the motor 11 are also possible. For example, the first microswitch 22 and the second microswitch 23 provide electrical signals for the circuit, and the circuit board provides different voltages for the motor, etc.
[0061] Among them, when the ejector rod 21 moves in the first direction, the ejector rod 21 can successively press the first contact 221 and the second contact 231. Specifically, when the ejector rod 21 moves downward, since both the first contact 221 and the second contact 231 are on the movement track of the ejector rod 21, the ejector rod 21 can first press the first contact 221, and then, the ejector rod 21 continues to move, and the ejector rod 21 then presses the second contact 231. When the first contact 221 and the second contact 231 are respectively pressed, the first microswitch 22 and the second microswitch 23 are respectively triggered, thereby providing an electrical signal for the motor 11, and the motor 11 can drive the stirring assembly 1 to stir food at different rotational speeds. When the ejector rod 21 presses the first contact 221, the blender is in the first gear; when the ejector rod 21 presses the second contact 231, the blender is in the second gear. That is, the user can control and select different gears through the ejector rod 21 to achieve different food stirring effects.
[0062] As Figure 3-6 shown, the present application provides a preferred embodiment of the above two-speed meat grinder.
[0063] As Figure 3 shown, preferably, the switch assembly 2 further includes a switch button 24, one end of which is connected to the ejector rod 21. When the switch button 24 is subjected to an external force, it can apply a force to the ejector rod 21 in the first direction to make the ejector rod 21 move towards the second position. Specifically, the switch button 24 can be pressed by the user and moves up and down on the upper cover part of the meat grinder. The outside of the switch button 24 can be made of soft rubber material to enhance the user's pressing experience. The switch button 24 can be designed to be the size of a palm for the user to directly press. Of course, the switch button 24 can also be designed to be the size of a finger for the user to press with a single finger.
[0064] Preferably, in order to limit the movement track of the switch button 24, the ejector rod 21 can be provided with a limit groove for the switch button 24, and the switch button 24 is provided with a limit post. The limit post of the switch button 24 is inserted into the limit groove of the switch button 24 so that the switch button 24 moves up and down in the limit groove.
[0065] As Figure 4 shown in the schematic diagram, preferably, the first micro switch 22 includes a first plane 222, and the first contact 221 is disposed on the first plane 222; the second micro switch 23 includes a second plane 232, and the second contact 231 is disposed on the second plane 232.
[0066] Wherein, the first plane 222 and the second plane 232 are disposed opposite to each other and inclined at an angle with respect to each other, so that when the ejector rod 21 moves in the first direction, the distances between the ejector rod 21 and the first plane 222 and the second plane 232 become smaller. Specifically, as Figure 4 shown, the first and second micro switches are vertically placed and inclined upward at an angle, so that there is an included angle β between the first plane 222 and the second plane 232. Specifically, the planes where the first plane 222 and the second plane 232 are located intersect to form an acute angle β, and the trajectory of the up and down movement of the ejector rod 21 is within the acute angle β. When the ejector rod 21 moves downward, the vertical distances between the ejector rod 21 and the first plane 222 and the second plane 232 both decrease.
[0067] Wherein, when the ejector rod 21 presses the first and second contacts, the first contact 221 and the second contact 231 can provide a force for the ejector rod 21 to move towards the second position by their own elastic force. Specifically, the first and second contacts are installed perpendicular to the first and second planes. Because the first plane 222 and the second plane 232 are disposed opposite to each other and inclined at an angle with respect to each other, after the first and second contacts are pressed, elastic forces F1 and F2 are provided, that is, F1 and F2 have upward components, which can push the ejector rod 21 to move upward, that is, the ejector rod 21 moves towards the second direction.
[0068] Preferably, the two-speed meat grinder of this embodiment includes a body 3, and the body 3 includes an ejector rod limiting groove for partially accommodating the ejector rod 21, so that the ejector rod 21 moves between the first position and the second position in the ejector rod limiting groove.
[0069] Preferably, one end of the ejector rod 21 includes a chamfer or a fillet 211, so that when the ejector rod 21 moves, the chamfer or the fillet 211 can press the first and second contacts. For example, the end of the ejector rod 21 has a chamfer 211. When the ejector rod 21 contacts the first contact 221, the chamfer 211 of the ejector rod 21 first contacts the first contact 221. When the ejector rod 21 continues to move downward, the inclined surface of the chamfer 211 can convert the downward stroke of the ejector rod 21 into the stroke of the first contact 221, so that the first contact 221 is pressed. Of course, the ejector rod 21 can also contact and press the first and second contacts in other forms.
[0070] Preferably, the switch assembly 2 includes a microswitch base 25, and the first and second microswitches are fixed to the microswitch base 25. Specifically, there are guide posts on the microswitch base 25, and guide holes on the first and second microswitches. The guide holes are placed on the guide posts to position the microswitches on the microswitch base 25. At the same time, the microswitch base 25 also has buckles. When the first and second microswitches are inserted into the guide posts, the buckles will hold the first and second microswitches to achieve fixation.
[0071] The microswitch base 25 can be directly fixed to the fuselage 3 or can move relative to the fuselage 3.
[0072] In other embodiments, when the microswitch base 25 is directly fixed to the fuselage 3, the ejector rod 21 presses the first contact 221 and the second contact 231 in sequence.
[0073] In this embodiment, when the microswitch base 25 can move relative to the fuselage 3, specifically, the microswitch base 25 can move between a third position and a fourth position. The microswitch base 25 includes an elastic element 251, which is externally fixed. The elastic element 251 can provide a force in the third direction for the microswitch base 25 to enable the microswitch base 25 to move from the fourth position to the third position. The third direction is the direction from the fourth position towards the third position. Of course, when the ejector rod 21 presses down on the first and second contacts, the ejector rod 21 can also provide a downward force for the microswitch base 25, causing the microswitch base 25 to move in the direction opposite to the third direction.
[0074] As Figure 6 shown, preferably, the fuselage 3 includes a microswitch base limiting groove 31 for partially accommodating the microswitch base 25, enabling the microswitch base 25 to move between the third position and the fourth position within the microswitch base limiting groove 31. For example, there is an extended column at the lower part of the microswitch base 25, and there is a limiting groove 31 on the fuselage 3 below the microswitch base 25 that cooperates with this column. The column is inserted into the limiting groove 31 so that the microswitch cannot move horizontally and the microswitch base 25 can only move up and down within the limiting groove 31. At the same time, the limiting groove 31 has a stop surface, and the extreme downward position of the microswitch base 25 is the fourth position. The microswitch base 25 can also have through holes, and the fuselage 3 includes columns. The columns pass through the through holes, enabling the microswitch base 25 to move up and down along the columns. There is a stop surface at the end of the column, and the extreme upward position of the microswitch base 25 is the third position. There is an elastic element 251 between the stop surface at the end of the column and the microswitch base 25, and the elastic element 251 provides an upward pulling force for the microswitch base 25. Of course, it should be understood that other structures for restricting the microswitch base 25 are also allowed.
[0075] As Figure 3As shown, when the push rod 21 does not press the first and second contacts, the micro switch seat 25 is located at the third position; Figure 5 As shown, when the push rod 21 presses the second contact 231, the micro switch seat 25 is located at the fourth position. Specifically, in this embodiment, when the push rod 21 presses the first contact 221, the micro switch seat 25 is located at the third position, and when the push rod 21 presses the second contact 231, the micro switch seat 25 is located at the fourth position. Of course, it should be understood that the positions of the push rod 21 pressing the first and second contacts can be achieved by adjusting the elastic coefficient of the elastic element 251. For example, by adjusting the elastic coefficient of the elastic element 251, when the micro switch seat 25 is located between the third position and the fourth position, the push rod 21 can press the first and second contacts respectively. For example, in other embodiments, the elastic element 251 has a different elastic coefficient, so that when the push rod 21 presses the first contact 221, the micro switch seat 25 is located between the third and fourth positions; when the push rod 21 presses the second contact 231, the micro switch seat 25 is located between the third and fourth positions. At this time, the push rod 21 can still move downward until the micro switch seat 25 is located at the fourth position.
[0076] The working mode of the double-speed meat grinder in this embodiment will be described below:
[0077] Specifically, the initial test state of the two-speed meat grinder is: the push rod 21 is located at the first position, and the micro switch seat 25 is located at the third position. At this time, the push rod 21 does not press the first and second contacts.
[0078] When the user presses the switch button 24 downward, the lower end of the switch button 24 drives the push rod 21 to move downward, so that the push rod 21 leaves the first position and moves downward along the first direction. When the push rod 21 contacts the first contact 221, the chamfer 211 of the push rod 21 contacts the first contact 221, and the push rod 21 continues to move downward. The downward running stroke of the push rod 21 is converted into the stroke of the first contact 221 by the chamfer 211, so that the first contact 221 is pressed. At this time, the motor 11 electrically connected to the first micro switch 22 receives an electrical signal, and the motor 11 works at the first speed. When the push rod 21 presses the first contact 221, it also presses the micro switch seat 25 connected to the first micro switch 22 downward. At this time, the elastic element 251 is stretched, and the elastic element 251 provides an upward elastic force to remind the user that the first gear is being turned on.
[0079] When the ejector rod 21 continues to move downward, the ejector rod 21 drives the microswitch seat 25 to move downward, and the elastic element 251 continues to be stretched. The elastic element 251 provides an upward resistance to remind the user that the first gear has been turned on and continuing to press the switch button 24 will turn on the second gear. When the microswitch seat 25 moves to the fourth position, the microswitch seat 25 cannot continue to move, and the ejector rod 21 can press the second contact 231, so that the second microswitch 23 provides an electrical signal to the motor 11, and the motor 11 rotates at the second speed.
[0080] When the user stops pressing the switch button 24, the elastic element 251 provides a force in the third direction to reset the switch push button seat 25 to the third position. At the same time, relying on their own elastic forces and the upward thrust provided by the switch push button seat 25, the first and second contacts push the ejector rod 21 upward, so that the pressed states of the first and second contacts are released, and the ejector rod 21 is reset to the first position.
[0081] According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present utility model should also fall within the protection scope of the claims of the present utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
