[0056] In order to better illustrate the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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”.

[0062] 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, or mill from being started when the switch knob is locked. An embodiment of the switch interlocking linkage device will be described below.

[0063] like Figure 1 As 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 .

[0064] like Figure 2 As shown, specifically, the slider 11 can move between a holding position and an opening position, and the slider 11 includes a slider body, and the slider body includes a first inclined surface 111. 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 for accommodating 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. The first inclined surface 111 of the slider body is located in the groove, which is convenient for effectively utilizing the space inside the slider 11 and reducing the structural volume. Of course, the structure in which the first inclined surface 111 is placed on the outer surface of the slider 11 or is placed on the slider 11 extending outside is also allowed.

[0065] The push rod 12 can move between a first position and a second position. The push rod 11 includes a push rod body, and the push rod body includes a second inclined surface 121. The second inclined surface 121 is interconnected with the first inclined surface 111. 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 11 can move up and down without position displacement. The second inclined surface 121 is a 45° inclined surface, which extends into the groove in the middle of the slider body and is mutually matched and connected with the first inclined surface 111. It should be understood that the first inclined surface 111 and the second inclined surface 121 can be set to other mutually matched shapes.

[0066] The switch push knob 13 can move between a locked position and an unlocked position. For example, the switch push knob 13 is located in front of the slider 11, is placed vertically, and can move up and down. The switch push knob 13 can have a protrusion or a handle portion extending from the middle of the switch push knob 13, so that the user can apply a force on the switch push knob 13 to make the switch push knob 13 move up and down. The protrusion or the handle portion can be provided with a surface that increases friction to facilitate user pressing. Of course, the switch interlock linkage device 1 can also be provided with a micro switch, and the downward movement of the switch push knob 13 can trigger the micro switch, thereby turning on the electrical appliance.

[0067] According to the principle of the utility model, when the slider 11 is in the holding position, the switch push knob 13 is in the locking position, and the slider 11 is connected and locked with the switch push knob 13 to keep the switch push knob 13 in the locking position; at this time, when the switch interlocking linkage device 1 is in the initial state, that is, the push rod 11 is in the first position, the slider 12 is in the holding position, and the slider 11 connects and locks the switch push knob 13, the switch push knob 13 is kept in the locking position, and the switch push knob 13 cannot move up and down.

[0068] Among them, the top rod 12 moves from the first position to the second position, and the top rod 12 can apply a force to the slider 11 toward the open position so that the slider 11 can move to the open position; at this time, the top rod is pressed by an external force, such as a user pressing or an upper cover of the grinder squeezing, and the top rod 12 moves from top to bottom. The top rod 12 applies a backward force to the first inclined surface 111 through the second inclined surface 121, so that the top rod 12 pushes the slider 11 to move horizontally in the backward direction until the slider 11 moves to the open position.

[0069] like Figure 3As shown, when the slider 11 is in the open position, the slider 11 is separated from the switch knob 13 to unlock the switch knob 13, and the switch knob 13 can move to the unlock position; at this time, the slider 11 is in the open position and the switch knob 13 is in the locked position. Because the two are separated from each other, the slider 11 is no longer connected and locked with the switch knob 13, so that the switch knob 13 can move downward freely. The present application can control the switch knob 13 from the locked state to the unlocked state by moving the slider 11 from the holding position to the open position, thereby improving the safety of the electrical appliance.

[0070] like Figure 4-9 As shown, the present application provides a preferred embodiment of the above-mentioned switch interlocking linkage device.

[0071] like Figure 4 As shown, preferably, in order to realize the automatic reset of the slider 11, that is, the slider 11 automatically moves from the open position to the holding position, the switch interlocking linkage device 1 further includes: a fixed seat 14, and the fixed seat 14 further includes a first spring seat 141; for example, the fixed seat 14 is located below the slider 11 and behind the switch push knob 13, so as to play a role in supporting the slider 11; the first spring seat 141 can be a baffle extending from the surface of the fixed seat 14, which is located on the extension line of the line segment where the holding position and the open position are located;

[0072] The slider body also includes a reset portion 112, which includes a first reset spring 1121, which is connected to the first spring seat 141, and the first reset spring 1121 enables the slider 11 to move toward the holding position; for example, the first reset spring 1121 directly presses and contacts with the baffle of the first spring seat 141, or there is a groove on the baffle, and the end face of the first reset spring 1121 is placed therein to prevent the first reset spring from shifting. Of course, other components that provide elastic force are also allowed to replace the first reset spring 1121, such as rubber parts, etc. The first reset spring 1121 can always provide elastic force for the slider 11 in the forward direction.

[0073] Furthermore, the reset portion 112 of the slider 11 may further include: a first limiting column 1122 facing the first spring seat 141 , and the first reset spring 1121 is sleeved on the first limiting column 1122 to prevent the first reset spring 1121 from moving and deviating.

[0074] like Figure 5As shown, preferably, the fixed seat 14 further includes a limiting groove 143, which is used to partially accommodate the slider 11, so that the slider 11 moves between the holding position and the opening position in the limiting groove 143. For example, the limiting groove 143 has a stopper at the holding position and the opening position, so that the limit position of the slider 11 moving forward and backward in the fixed seat 14 is the holding position and the opening position; at the same time, the slider 11 has an extended buckle, which clamps the lower surface of the fixing seat limiting groove 143, so that the slider 11 cannot move up and down, so that the slider 11 moves between the holding position and the opening position in the limiting groove 143.

[0075] like Figure 6 As shown, preferably, in order to realize the automatic resetting of the ejector rod 12, that is, the ejector rod 12 automatically moves from the second position to the first position, the fixing seat 14 further includes a second spring seat 142; for example, in order to simplify the structure, the second spring seat 142 is the upper surface of the fixing seat 14;

[0076] The main body of the push rod further includes a reset portion 122, the reset portion 122 includes a second reset spring 1221, the second reset spring 1221 is connected to the second spring seat 142, and the second reset spring 1221 enables the push rod 12 to move toward the first position. The reset portion 122 of the push rod 12 may have the same structure as the reset portion 112 of the slider 11. It should be understood that the second spring seat 142 and the second reset spring 1221 may be placed in other positions, for example, above the push rod 12, and the second reset spring 1221 provides an upward pulling force for the push rod 12.

[0077] like Figure 7 As shown, preferably, the switch push and turn body also includes a reset portion 132, and the reset portion 132 includes a third reset spring 1321, and the third reset spring 1321 is externally fixed, and the third reset spring 1321 enables the switch push and turn 13 to move toward the locked position. Further preferably, the reset portion 132 of the switch push and turn 13 can also include a third limit column 1322, and the third reset spring 1321 is sleeved on the third limit column 1322. It should be understood that the third reset spring 1321 can be externally connected to the switch push and turn seat 15, and can also be externally connected to an electrical appliance, such as a grinder. Of course, the third reset spring 1321 can also be connected to the fixed seat 14.

[0078] Furthermore, the switch push-twist seat 15 includes a limiting groove 151, which is used to partially accommodate the switch push-twist 13, so that the switch push-twist 13 can move between the unlocking position and the locking position in the limiting groove 151. For example, the switch push-twist 13 and the switch push-twist seat 15 are designed to be tile-shaped, the switch push-twist seat 14 has a groove in the middle, and the handle of the switch push-twist 13 is placed in the groove, so that the switch push-twist 13 can move between the locking position and the unlocking position in the groove.

[0079] like Figure 8As shown, preferably, the slider body further includes a blocking portion 113; for example, the blocking portion 113 is two square pieces extending from the slider 11, and the square pieces have an upper surface;

[0080] The switch push knob 13 also has a locking portion 131. Specifically, the locking portion 131 is a hook portion 1311. The hook portion 1311 can be hooked on the blocking portion 113 to keep the switch push knob 13 in the locked position. For example, the hook portion 1311 is two "Γ"-shaped hooks. When the hook portion 1311 is hooked on the blocking portion 113, the hook portion 1311 contacts the upper surface of the blocking portion 113. When the switch push knob 13 moves downward, the blocking portion 113 blocks the hook portion 1311 from moving downward, so that the switch push knob 13 cannot move downward. Of course, it should be understood that in other embodiments, the locking portion 131 and the blocking portion 113 can also be other shapes that match each other, such as a concave portion and a convex portion, and the convex portion of the slider 11 / switch push knob 13 is inserted into the concave portion of the switch push knob 13 / slider 11 to achieve connection locking.

[0081] In the above embodiment, if the user presses the switch knob 13 for too long, there is a situation where the slider 11 has been reset to the holding position, but the switch knob 13 is still in the unlocking position. At this time, the slider 11 will prevent the switch knob 13 from resetting from the unlocking position to the locking position. In order to solve this problem,

[0082] Preferably, the slider body includes a third inclined surface 114 facing the unlocking position, for example, the third inclined surface 114 is provided on the lower surface of the slider blocking portion 113;

[0083] When the slider 11 is in the holding position and the switch knob 13 is in the unlocking position and moving toward the locking position, the switch knob 13 can provide a force to push the slider 11 toward the opening position through the third inclined surface 114, so that the slider 11 moves toward the opening position. For example, when the switch knob 13 moves from bottom to top, the slider 11 is blocked from continuing to move upward because it is in the holding position. At this time, the end of the "Γ"-shaped hook 1311 contacts the third inclined surface 114 of the slider 11, so that the switch knob 13 pushes the slider 11 to move backward, and the switch knob 13 can continue to move upward until the switch knob 13 reaches the locking position. At this time, in order to realize the automatic reset of the slider 11 to the holding position,

[0084] Furthermore, the fixing seat 14 further includes a first spring seat 141, and the slider body further includes a reset portion 112, the reset portion 112 includes a first reset spring 1121, the first reset spring 1121 is connected to the first spring seat 141, and the first reset spring 1121 enables the slider 11 to move toward the holding position. For example, due to the action of the first reset spring 141, the inclined surface 114 of the slider 11 is pressed against the switch push knob, and when the switch push knob 13 is reset to the locked position, the slider 11 is also connected and locked with the switch push knob 13 at the same time.

[0085] In the above embodiment, the switch push knob 13 moves upward due to the elastic force of the third return spring 1321 until the switch push knob 13 contacts the slider 11 at the holding position; then, the hook 1311 contacts the third inclined surface 114 of the slider 11, so that the slider 11 moves backward, and the switch push knob 13 can continue to move upward to the locking position. Finally, the slider 11 moves toward the first position due to the elastic force of the first return spring 1121 until it is reconnected and locked with the switch push knob 13 at the holding position.

[0086] like Fig. 9 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.

[0087] 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 .

[0088] The lower body 3 may have an inner cavity 31 therein, and the switch interlocking linkage device 1 is installed in the inner cavity 31 .

[0089] Preferably, the lower body 3 may further include a limiting groove 32 for partially accommodating the ejector rod 12 so that the ejector rod 12 can move between the first position and the second position in the limiting groove 32 .

[0090] The working principle of the switch interlocking linkage device 1 in the coffee grinder is:

[0091] When the upper cover 2 does not cover the lower body 3, the first return spring 1121 exerts a forward elastic force on the slider 11, so that the slider 11 can always be in the holding position; similarly, the top rod 12 can always be in the first position, and the switch push knob 13 can always be in the locking position. The hook portion 1311 of the switch push knob 13 is hooked on the blocking portion 113 of the slider 11, so that the switch push knob 13 cannot move downward.

[0092] When the upper cover 2 covers the lower body 3, the upper cover 2 pushes the push rod 12, and the push rod 12 moves downwards against the elastic force of the second return spring 1221. The first inclined surface 111 of the push rod 12 pushes the second inclined surface 121 to move the slider 11 backwards, so that the slider reaches the open position. At this time, the hook portion 1311 of the switch knob 13 is separated from the blocking portion 113, and the switch knob 13 can move downwards, and the switch knob 13 is unlocked.

[0093] 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. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
