[0002] A coffee bean grinder is a household appliance for grinding coffee beans. Its motor drives the cutter to rotate and grind the food in the grinder into powder.
[0003] For example, in the Chinese patent document with publication number CN202778633U, a multifunctional coffee grinder is disclosed, including an upper cover, a main body shell, a switch, and a motor. After the switch of the coffee grinder is turned on, the motor rotates and the coffee grinder starts to work. When the upper cover of the coffee grinder and the main body shell are not tightly closed, the switch can still be used, which poses a safety hazard. Utility Model Content
[0004] The purpose of the utility model is to provide a switch interlocking linkage device and a coffee grinder thereof, aiming to solve the above-mentioned unsafe problem.
[0005] In order to achieve the above-mentioned object, according to the first aspect of the present application, the present application provides a switch interlocking linkage device, comprising:
[0006] A slider capable of moving between an unlocked position and a locked position; the slider comprising a micro switch capable of being turned on by being pressed;
[0007] A push rod, which can move between a holding position and an opening position, one end of which is connected to the slider;
[0008] A switch push knob capable of moving between a first position and a second position;
[0009] When the slider is in the locked position, the switch push knob is away from the micro switch, and the switch push knob cannot press and turn on the micro switch.
[0010] When the push rod moves from the holding position to the opening position, the push rod applies a force toward the unlocking position to the slider, so that the slider can move to the unlocking position.
[0011] When the slider is located at the unlocking position, the switch push knob is close to the micro switch, so that when the switch push knob moves from the first position to the second position, the micro switch can be pressed to turn on.
[0012] Compared with the prior art, the switch interlock linkage device of the embodiment of the present application is provided with a slider, a push rod, and a switch push knob. When the slider is in the locked position, because the switch push knob is far away from the micro switch on the slider, the switch push knob cannot press and turn on the micro switch even if it moves. Through the connection between the push rod and the slider, when the push rod moves from the holding position to the opening position, the slider can move from the locked position to the unlocked position. At this time, the switch push knob changes from being away from the micro switch to being close to the micro switch. At this time, when the switch push knob moves from the first position to the second position, the switch push knob can press and turn on the micro switch. The present application can control the switch push knob to press the micro switch by placing the slider in the locked position or the unlocked position, thereby improving the safety of the use of the electrical appliance.

[0014] By providing the first return spring, the first return spring can provide an elastic force for the slider to move toward the locking position, thereby making it possible for the slide bar to automatically return to the locking position.
[0015] In some embodiments, the micro switch includes a micro switch contact, and when the distance the micro switch contact is pressed is greater than or equal to a starting distance, the micro switch is pressed and started.
[0016] By setting the micro switch contacts, the micro switch is only pressed and started when the switch push knob presses the micro switch contacts for a distance greater than or equal to the starting distance, thereby further controlling the conditions for the micro switch to start, preventing the micro switch from being accidentally touched, and improving the safety of the device.
[0017] In some embodiments, the micro switch further includes a movable arm, one end of which is connected to the micro switch and the other end is external, and the movable arm cooperates with the micro switch contact to be pressed.
[0018] By setting up the movable arm, the pressing mode of the switch push-twist and the micro switch contact can be converted into the pressing mode of the contact part and the movable arm, so that the contact part changes from pressing a contact with a smaller pressure to pressing a movable arm with a larger pressure. The contact part can better control the pressing distance, further improving the safety of the switch interlocking linkage device.
[0019] In some embodiments, the slider includes a slider body, the slider body includes a first inclined surface, and the push rod includes a second inclined surface; the first inclined surface and the second inclined surface are cooperatively connected to each other so that the push rod can apply a force to the slider toward the unlocked position.
[0020] By providing the first inclined plane and the second inclined plane, the slider can move from the locking position to the unlocking position when the push rod moves from the holding position to the opening position in a limited space, and the inclined plane structure is simple and reliable, thereby improving the reliability of the device.
[0021] In some embodiments, the switch push knob further includes a reset portion, the reset portion includes a second reset spring, the second reset spring is externally fixed, and the second reset spring enables the switch push knob to move toward the first position.
[0022] By providing the second reset spring, when the switch knob is located at the second position, the second reset spring provides elastic force to the switch knob so that the switch knob can move toward the first position, thereby providing the possibility for the switch knob to automatically reset to the first position.
[0023] In some embodiments, the switch interlock linkage device also includes a switch push-twist seat, and the switch push-twist seat includes a switch push-twist limiting groove, which is used to partially accommodate the switch push-twist, so that the switch push-twist can move between a first position and a second position in the switch push-twist limiting groove.
[0024] By setting the switch push and turn limit groove, the trajectory of each push and turn movement of the switch is consistent, thereby increasing the reliability of the structure.
[0025] According to a second aspect of the present application, the present application provides a coffee bean grinder, which includes a switch interlocking linkage device as described in any one of the above embodiments.
[0026] In some embodiments, the coffee bean grinder includes a lower body, and the lower body includes a limiting groove, which is used to partially accommodate the top rod, so that the top rod moves between an open position and a holding position in the limiting groove.
[0027] By setting the limiting groove of the ejector rod, the trajectory of each movement of the ejector rod is made consistent, thereby increasing the reliability of the structure.
[0028] In some embodiments, the coffee bean grinder includes a lower body, and the lower body includes a limiting column;
[0029] The slider body further comprises a track groove, which partially accommodates the limiting column, and the track groove cooperates with the limiting column so that the slider can move along the track groove between a locking position and an unlocking position.

[0048] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.
[0049] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.
[0050] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the embodiments of the present application.

It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.
[0051] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and do not have to be used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.
[0052] In addition, in the description of this application, unless otherwise specified, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.
[0053] In the description of the present application, upward and downward directions are defined as “vertical directions”, and forward and backward directions are defined as “horizontal directions”.
[0054] The present application provides a switch interlocking linkage device, which can control the locking and unlocking of a switch knob, thereby preventing an electrical appliance from being started when the switch knob is locked, thereby improving the safety of the electrical appliance. For example, the switch interlocking linkage device can be installed on a bean grinder, a blender, a mill, etc., and can prevent the bean grinder, blender, mill, etc. from being started when the switch knob is locked. An embodiment of the switch interlocking linkage device will be described below.
[0055] like Figure 1As shown, the switch interlocking linkage device 1 provided in the present application includes a slider 11 , a push rod 12 , and a switch push knob 13 .
[0056] like Figure 2 As shown, specifically, the slider 11 can move between an unlocking position and a locking position; the slider 11 includes a micro switch 111, which can be turned on by pressing. For example, the slider 11 is placed in the horizontal direction and moves back and forth in the horizontal direction. There is a groove in the middle of the slider body 112, which is used to accommodate the push rod 12 so that the push rod 12 can move in the groove. The groove can not only limit the push rod 12 and enhance the reliability of the structure, but also make the spatial structure of the slider 11 and the push rod 12 more compact.
[0057] The push rod 12 can move between the holding position and the opening position, and one end of the push rod 12 is connected to the slider 11. For example, the push rod 12 is located above the slider 11, and the push rod 12 is placed in the vertical direction and moves up and down in the vertical direction. The push rod 12 is in the shape of an elongated strip, and the lower end of the push rod 12 extends into the groove of the slider 11, which can limit part of the stroke of the push rod 12, so that the push rod 12 can move up and down without position displacement. The connection between the push rod 12 and the slider 11 can be in the form of two surface contacts, two point contacts, or point and surface contacts.
[0058] The switch knob 13 can move between a first position and a second position. For example, the switch knob 13 is located in front of the slider 11, is placed vertically, and can move up and down. The switch knob 13 can have a protrusion or a handle extending from the middle of the switch knob 13, so that the user can apply a force on the switch knob 13 to make the switch knob 13 move up and down. The protrusion or the handle can be provided with a surface that increases friction, so that the user can press it.
[0059] According to the principle of the present utility model, when the slider 11 is in the locked position, the switch push knob 13 is away from the micro switch 111, and the movement of the switch push knob 13 cannot press and turn on the micro switch 111. At this time, the switch interlocking linkage device 1 is in the initial state, that is, the push rod 12 is in the holding position, the slider 11 is in the locked position, and the slider 11 is away from the switch push knob 13. For example, the slider 11 is separated from the switch push knob 13 by a certain distance, so that even if the switch push knob 13 moves up and down, it cannot touch the micro switch 111, and the micro switch 111 cannot be pressed to turn on.
[0060] When the top rod 12 moves from the holding position to the opening position, the top rod 12 applies a force toward the unlocking position to the slider 11 so that the slider 11 can move to the unlocking position. At this time, the top rod 12 is pressed by an external force, such as a user pressing or the upper cover of the grinder squeezing, and the top rod 12 moves from top to bottom, so that the top rod 12 pushes the slider 11 to move forward horizontally through the connection with the slider 11 until the slider 11 moves to the unlocking position.
[0061] like Figure 3 As shown, when the slider 11 is in the unlocked position, the switch knob 13 is close to the micro switch 111, so that the switch knob 13 moves from the first position to the second position to press and turn on the micro switch 111. At this time, the slider 11 is in the unlocked position, and the switch knob 13 is in the first position, for example, the distance between the two is close enough or they are against each other, so that the micro switch 111 of the slider 11 is also close to the switch knob 13, so that the switch knob 13 can move downward to contact and press and turn on the micro switch 111. The present application controls whether the switch knob 13 can press and turn on the micro switch 111 by placing the top rod 11 in the holding position or the opening position, thereby improving the safety of the electrical appliance.
[0062] like Figure 4-7 As shown, the present application provides a preferred embodiment of the above-mentioned switch interlocking linkage device.
[0063] like Figure 4 As shown, preferably, the slider body 112 also includes a reset portion 1121, and the reset portion 1121 includes a first reset spring 11211, which is externally fixed, and the first reset spring 11211 enables the slider 11 to move toward the locked position. For example, there is a spring fixing seat on the grinder, and the fixing seat is located behind the slider 11. The first reset spring 11211 is fixed on the spring seat, and the first reset spring 11211 is in a stretched state, providing a pulling force to both ends, so that the slider 11 can move backward. It is also allowed for the spring fixing seat to be located in other positions, such as in front of the slider 11. At this time, the first reset spring 11211 provides pressure to make the slider 11 move backward. Of course, it is also allowed for other components that provide elastic force to replace the first reset spring 11211, such as rubber parts.
[0064] In this embodiment, the re-unlocking process of the switch interlock linkage device 1 is as follows: when the push rod is no longer subjected to external force, the slider 11 is reset to the locked position due to the action of the first reset spring 11211, and the push rod 12 is reset to the holding position by the action of the slider 11. At this time, the slider 11 is away from the switch push knob 13, so that the switch push knob 13 cannot trigger the micro switch 112 even if it moves up and down.
[0065] Furthermore, the reset portion 11211 of the slider 11 further includes a limiting column 11212, and the first reset spring 11211 is sleeved on the limiting column 11212. Of course, in other embodiments, the limiting column 11212 may also be changed into a groove on the reset portion 1121, and the first reset spring 11211 is placed in the groove to prevent the position and direction of the first reset spring 11211 from being offset. Similarly, the position where the first reset spring 11211 is externally fixed may also have a limiting column or groove to simultaneously limit the position and direction of the first reset spring 11211.
[0066] Furthermore, the top rod 12 may also be provided with a reset portion, which includes a reset spring. A spring fixing seat of the reset spring is provided on the grinder or a spring fixing seat is provided on the slider 11 to provide an elastic force for the top rod 12 toward the holding position, so as to help the top rod 12 automatically reset to the holding position when the top rod 12 is not subjected to external force.
[0067] Preferably, the micro switch 111 includes a micro switch contact 1111. When the distance of the micro switch contact 1111 being pressed is greater than or equal to the activation distance, the micro switch 111 is activated by pressing. In order to cooperate with the pressing of the micro switch contact 1111, the switch push knob 13 can also be provided with a contact portion 131, and the contact portion 131 is a raised component, which further facilitates pressing the micro switch contact 1111. The working mode of the micro switch contact 1111 is described below:
[0068] When the slider 11 is in the locked position, the contact portion 131 of the switch knob 13 cannot press the micro switch contact 1111, or the contact portion 131 can press the micro switch contact 1111, but the distance of the micro switch contact 1111 being pressed is less than the starting distance. Specifically, when the slider 11 is in the first position, the slider 11 is far away from the switch knob 13, resulting in that the contact portion 131 of the switch knob 13 cannot press the micro switch contact 1111 even if it moves up and down; or in other embodiments, the slider 11 is separated from the switch knob 13 by a distance, and the switch knob 13 can press the micro switch 111 when it moves up and down, but because the distance between the slider 11 and the switch knob 13 is not enough to make the switch knob 13 move up and down and completely press the starting distance of the micro switch contact 1111, the micro switch 111 cannot be pressed to turn on.
[0069] When the slider 11 is in the unlocked position, the distance that the contact portion 131 presses the micro switch contact 1111 can be greater than or equal to the start distance. Specifically, when the slider 11 is in the unlocked position, the slider 11 completely abuts against the switch push knob 13, and the switch push knob 13 moves downward, so that the contact portion 131 presses the micro switch contact 1111, so that the micro switch 111 is pressed and turned on; or in other embodiments, the slider 11 and the switch push knob 13 are still separated by a distance, but when the switch push knob 13 moves downward, the contact portion 131 can press the micro switch contact 1111 to a deeper distance, which is greater than or equal to the start distance, and the micro switch 111 is pressed and turned on.
[0070] Preferably, the micro switch 111 also includes a movable arm 1112, one end of which is connected to the micro switch 111, and the other end is external, and the movable arm 1112 cooperates with the micro switch contact 1111 to press. For example, the angle between the movable arm 1112 and the micro switch is set to 15°. There is a connection point between the movable arm 1112 and the micro switch 111, and the micro switch contact 1111 is set near the connection point. When the contact portion 131 presses the movable arm 1112, the angle between the movable arm 1112 and the micro switch becomes 0°, and the micro switch is activated. It should be understood that other angles set for the movable arm 1112 and other activation distances set for the micro switch 111 are also allowed.
[0071] Preferably, the slider body 112 includes a first inclined surface 1122, and the push rod 12 includes a second inclined surface 121; the first inclined surface 1122 and the second inclined surface 121 are mutually matched and connected, so that the push rod 12 can apply a force to the slider 11 toward the unlocking position. For example, the first inclined surface 1122 of the slider body 112 is located in a groove in the middle of the slider body 112, which is convenient for effectively utilizing the space inside the slider 11 and reducing the structural volume. Of course, the first inclined surface 1122 is placed on the outer surface of the slider 11 or is placed on the structure extending outside the slider 11. The first inclined surface 1122 of the slider 11 and the second inclined surface 121 of the push rod 12 are both 45° inclined surfaces, and the second inclined surface 121 extends into the groove in the middle of the slider body 112 and is mutually matched and connected with the first inclined surface 1122. It should be understood that the first inclined surface 1112 and the second inclined surface 121 can be set to other mutually matched shapes.
[0072] like Figure 5As shown, preferably, the switch push knob 13 also includes a reset portion 132, and the reset portion 132 includes a second reset spring 1321, which is externally fixed, and the second reset spring 1321 enables the switch push knob 13 to move toward the first position. For example, the grinder has a spring fixing seat, and the second reset spring 1321 is fixed on the spring seat; or, the switch interlocking linkage device 1 can also include a switch push knob seat 14, and the switch push knob seat 14 has a spring fixing seat, and the second reset spring 1321 is fixed on the spring seat. Like the reset portion 1121 of the slider 11, the reset portion 132 of the switch push knob 13 can also have a limiting column 1322.
[0073] Preferably, in order to enable the switch push knob 14 to move between the first position and the second position, the switch push knob seat 14 includes a switch push knob limiting groove 141, which is used to partially accommodate the switch push knob 13, so that the switch push knob 13 moves between the first position and the second position in the switch push knob limiting groove 141. For example, the switch push knob 13 and the switch push knob seat 14 are designed to be tile-shaped, the switch push knob seat 14 is grooved in the middle, and the handle of the switch push knob 13 is placed in the groove, so that the switch push knob 13 moves between the first position and the second position in the groove.
[0074] like Figure 6 As shown, finally, the present application also provides a coffee bean grinder, including the switch interlocking linkage device 1 as described above. Specifically, the coffee bean grinder includes an upper cover 2 and a lower body 3. The upper cover 2 is located above the lower body 3.
[0075] The upper cover 2 can cover the lower body 3 , and when the upper cover 2 covers the lower body 3 , the upper cover 2 can press the ejector rod 12 .
[0076] The lower body 3 may have an inner cavity, in which the switch interlocking linkage device 1 is installed.
[0077] The working principle of the switch interlocking linkage device 1 in the coffee grinder is:
[0078] When the upper cover 2 does not cover the lower body 3, the first return spring 11211 applies a backward elastic force to the slider 11, so the slider 11 is always in the locked position and the slider is away from the switch push knob 13; at the same time, the first inclined surface 1122 of the slider body 112 is connected to the second inclined surface 121 of the push rod 12, so that the push rod 12 is always in the holding position. Similarly, the second return spring 1321 applies an upward elastic force to the switch push knob 13, so that the switch push knob 13 is always in the holding position. At this time, even if the switch push knob 13 moves up and down, the contact portion 131 cannot press the micro switch contact 1111.
[0079] When the upper cover 2 covers the lower body 3, the upper cover 2 pushes the push rod 12 to move downward. The push rod 12 applies a forward force to the slider 11, so that the slider 11 moves to the unlocked position. At this time, the switch push knob 14 is pressed by the user, and the contact part 131 presses the movable arm 1112, so that the micro switch contact 1111 is pressed by the passive arm 1112 to a distance greater than or equal to the activation distance, and the micro switch 112 is activated.
[0080] Preferably, in order to enable the push rod 12 to move between the holding position and the opening position, the lower body 3 includes a limiting groove 31, which is used to partially accommodate the push rod 12, so that the push rod 12 can move between the opening position and the holding position in the limiting groove 31.
[0081] like Figure 7 As shown, preferably, in order for the slider 11 to be able to move between the locked position and the unlocked position, the lower body 3 also includes a limiting column 32; the slider body 112 also includes a track groove 1123, which partially accommodates the limiting column 32, and the track groove 1123 cooperates with the limiting column 32 so that the slider 11 can move between the locked position and the unlocked position along the track groove 1123. For example, the track groove 1123 is a runway type, and the limiting column 32 is a cylindrical type. When one end of the track groove 1123 contacts the limiting column 32, the limiting column 32 blocks the slider 11 from continuing to move, so that the movement trajectory of the slider 11 is limited by the track groove 1123, and the slider 11 can only move linearly between the unlocked position and the locked position. In other embodiments, the track groove 1123 can also be rectangular, and the cross section of the limiting column 32 is a matching rectangle. It should be understood that other structures that limit the slider 11 to move between the locked position and the unlocked position are also allowed.
[0082] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation.
