Description

Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a split-type food processor. Background Technology

[0002] A detachable food processor is a common kitchen appliance, typically consisting of a base and a removable cup. The bottom of the cup has an upper drive head, and the base has a lower drive head. When the cup is placed on the base, the lower drive head engages with the upper drive head, driving the blade assembly inside the cup to rotate, thus achieving functions such as blending and pulverizing.

[0003] In existing detachable blenders, the motor's start and stop are typically controlled by a switch on the base. Additionally, an electronically controlled interlocking switch is installed between the cup and the base for further safety protection. When the cup is placed on the base, it triggers a microswitch or sensor within the base, closing the circuit and allowing the motor to run when the user operates the control switch. If the cup is removed during operation, the interlocking switch releases, cutting off the motor circuit and preventing further operation. Therefore, the protection logic of existing detachable blenders is "remove the cup first, then cut off the power and stop."

[0004] However, this type of protection logic still has shortcomings: On the one hand, users can still remove the cup while the motor is running, and the motor only stops passively after the cup is removed. Due to inertia, the motor and transmission components will continue to rotate for a short period of time, and the lower drive head will be exposed during this period, posing a safety hazard. On the other hand, the cup and the base are coupled by the upper and lower drive heads. When the user removes the cup while the motor is running, especially if the cup is not lifted vertically, the upper and lower drive heads may experience eccentric friction or jamming during rotation, which may lead to wear or damage to the parts and increase the risk of use.

[0005] In summary, the existing protection logic of "removing the cup first and then cutting off the power to stop the machine" in the case of separate food processors is lagging and cannot eliminate safety hazards. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] The purpose of this invention is to provide a detachable blender to solve the problem that existing detachable blenders use a protection logic of removing the cup first and then cutting off the power to stop the machine. This allows users to remove the cup while the motor is running, resulting in a delayed protection mechanism and potential safety hazards during the inertial rotation of the motor and the separation of transmission components.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides a detachable food processor, including a base, a cup body, and a cup lid. The cup body is equipped with a blade assembly, the base is equipped with a drive motor, and the base is equipped with a support arm. The cup body is placed on the base, and the support arm is located on the outside of the cup body. The cup lid is mounted on the support arm and is able to move relative to the support arm between a first position and a second position; The support arm is provided with a position detection element, and the cup lid is provided with a trigger part. The trigger part cooperates with the position detection element to detect whether the cup lid is in the first position, and controls the circuit of the drive motor to close when the cup lid is in the first position and to open when the cup lid deviates from the first position. Furthermore, when the cup lid is in the first position, it cooperates with the base and the support arm to form a limiting cavity for limiting the cup body and covers the mouth of the cup body; when the cup lid is in the second position, the limiting cavity is released and the cup body can be removed from the base.

[0010] Furthermore, the cup lid is connected to the support arm via a pivot, and the cup lid can rotate around the pivot between the first position and the second position.

[0011] Furthermore, the pivot is arranged horizontally, and the cup lid can rotate up and down between the first position and the second position around the pivot.

[0012] Furthermore, the rotating shaft is arranged vertically, and the cup lid is capable of rotating around the rotating shaft in a plane between the first position and the second position.

[0013] Furthermore, the cup lid is slidably connected to the support arm via a guide structure and can slide between the first position and the second position along the guide structure.

[0014] Furthermore, at least one of the cup body and the support arm is provided with a mounting cavity, and a locking member that can move between an unlocked position and a locked position is provided in the mounting cavity; the cup lid is provided with a locking part that cooperates with the locking member; when the cup lid is in the first position, the locking member engages with the locking part, so that the cup lid is held in the first position and together with the base and the support arm forms the limiting cavity; when the locking member is in the unlocked position, the locking member disengages from the locking part, so that the cup lid can deviate from the first position.

[0015] Furthermore, a first elastic element is provided between the cup lid and the support arm, and the first elastic element applies an elastic force to the cup lid to move it toward the second position.

[0016] Furthermore, a second elastic element is provided within the mounting cavity, which applies a spring force to the locking element to move it toward the locking position.

[0017] Furthermore, it also includes an unlocking component, which is connected to the locking component. When subjected to external force, the unlocking component can overcome the elastic force of the second elastic component and drive the locking component to move from the locked position to the unlocked position.

[0018] Furthermore, the triggering part and the position detection element can be coupled in the following ways: a protrusion and a micro switch, a magnet and a magnetic control switch, or a magnet and an induction coil.

[0019] (III) Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model discloses a detachable food processor. A support arm is mounted on the base, and the lid is mounted on the support arm, allowing the lid to move between a first position and a second position relative to the support arm. A position detection element is installed on the support arm, and a trigger element is installed on the lid. These two elements work together to detect whether the lid is in the first position and control the on / off state of the motor circuit accordingly. Therefore, when the lid is in the first position, the motor circuit is closed, and the motor is allowed to run when the user operates the control switch. Once the lid deviates from the first position, the motor circuit is immediately disconnected, and the drive motor cannot run even if the user operates the control switch. In this way, any initial action of opening the lid or removing the cup will first cut off the circuit, eliminating the risk of the drive motor continuing to run while the user is removing the cup.

[0021] Simultaneously, when the lid is in the first position, it, together with the base and support arm, forms a limiting cavity to position and constrain the cup, covering the opening of the cup. Thus, while the drive motor is allowed to operate, the cup is reliably restrained on the base, preventing the user from directly removing it. Only when the lid deviates from the first position to the second position will the limiting cavity be released, allowing the cup to be removed from the base. In other words, the prerequisite for removing the cup is that the lid must first deviate from the first position, and this action will first cause the motor circuit to disconnect before the limiting cavity is released. This naturally achieves the safe sequence of "stopping the machine before removing the cup."

[0022] This invention ensures the safety logic of "the cup can only be removed when the power is off and the machine is stopped" by prioritizing the cutting off of the motor circuit when the cup lid deviates from the first position, combined with the mechanical constraint of the cup lid forming a limiting cavity in the first position. This completely solves the safety hazards in the prior art and improves the safety of using the detachable food processor. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0031] In the description of this utility model, it should be noted that the terms "center", "middle", "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", "side", "vertical", "horizontal", "first", "second", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] This embodiment provides a detachable food processor, including a base, a cup body, and a lid. A drive motor is housed within the base, and a support arm is mounted on the base. The support arm can be integrally formed from the outer shell of the base, or it can be a separate component fixed to the base. A blade assembly is housed within the cup body, which rests on the base, with the support arm located on the outer side of the cup body. When the drive motor rotates, it drives the blade assembly to rotate, thereby blending the ingredients within the cup body.

[0034] The lid is mounted on the support arm and can move between a first position and a second position relative to the support arm. The first position is when the lid covers and closes the mouth of the cup, and the second position is when the lid moves away from the mouth of the cup.

[0035] A position detection element is installed on the support arm, and a trigger is installed on the cup lid. The two work together to detect whether the cup lid is in the first position and control the on / off state of the motor circuit accordingly. When the cup lid is in the first position, the trigger and the position detection element work together to close the motor circuit, allowing the motor to run when the user operates the control switch. When the cup lid deviates from the first position, the position detection element no longer detects the trigger, the motor circuit is disconnected, and the motor cannot run even if the user operates the control switch.

[0036] Furthermore, when the cup lid is in the first position, it works together with the base and support arm to form a limiting cavity for positioning and constraining the cup, restricting the cup to the base and covering the mouth of the cup, thereby preventing the cup from being removed during motor operation; when the cup lid moves from the first position to the second position, the position detection element can no longer detect the action of the trigger, the motor circuit is disconnected, the drive motor stops running, and at the same time the limiting cavity is released, allowing the cup to be safely removed from the base.

[0037] The above design achieves the safety logic of "cup removal only after power failure and machine shutdown". That is, when the drive motor is running, the cup is reliably restrained on the base and cannot be removed by the user. Only when the cup lid deviates from the first position and the drive motor circuit is cut off can the cup be removed from the base. This avoids the safety hazards caused by the "cup removal first, then power failure and machine shutdown" logic in the prior art and effectively improves the safety of user operation and user experience.

[0038] The following explanation, in conjunction with the accompanying drawings, will provide further details. Example 1

[0039] refer to Figure 1 and Figure 2This embodiment provides a detachable food processor, including a base 1, a cup body 2, and a lid 3. The base 1 houses a drive motor 11, and a support arm 12 is integrally formed from the outer shell of the base 1. The cup body 2 houses a blade assembly 21, and the cup body 2 is placed on the base 1, with the support arm 12 located on the outer side of the cup body 1. The drive motor 11 is coupled to an upper drive head at the bottom of the cup body 2 via a lower drive head on the base 1, driving the blade assembly 21 to rotate, thereby blending the ingredients inside the cup body 1.

[0040] The cup lid 3 is connected to the support arm 12 via a pivot 31, and the pivot 31 is arranged in a horizontal direction, so that the cup lid 3 can be flipped between a first position and a second position around the pivot 31. The first position is when the cup lid 3 covers and closes the mouth of the cup body 2, and the second position is when the cup lid 3 is flipped to a position away from the mouth of the cup body 1.

[0041] A first elastic element is provided between the support arm 12 and the cup lid 3. In this embodiment, the first elastic element is a torsion spring 32 sleeved on the rotating shaft 31, which is used to apply a torsional elastic force to the cup lid 3 to move it toward the second position, so that when it is not locked, the cup lid 3 can naturally flip to the second position.

[0042] A position detection element 121 is provided on the support arm 12, and a trigger part 33 corresponding to the position detection element is provided on the cup lid 3. The two cooperate to detect whether the cup lid 3 is in the first position, and control the on / off state of the motor circuit accordingly. (Reference) Figure 1 , Figure 2 and Figure 3 In this embodiment, the position detection element 121 is a micro switch, and the trigger part 33 is a protrusion on the cup lid 3. When the cup lid 3 is in the first position, the protrusion presses against the micro switch, closing the motor circuit, so that the drive motor 11 can run when the user operates the control switch on the base; once the cup lid 3 begins to deviate from the first position, the protrusion gradually disengages from the contact of the micro switch, disconnecting the motor circuit, so that the drive motor 11 cannot run even if the user operates the control switch.

[0043] refer to Figure 1 , Figure 2 and Figure 4 To achieve mechanical limiting, a locking part 34 is provided on the cup lid 3, and a mounting cavity is provided inside the handle of the cup body 2, with a locking element 4 installed inside the mounting cavity. The locking element 4 can slide between a locked position and an unlocked position. When the locking element 4 is in the locked position, it engages with the locking part 34, keeping the cup lid 3 in the first position, and together with the base 1 and the support arm 12, forms a limiting cavity, thereby restricting the cup body 2 onto the base 1. When the locking element 4 is in the unlocked position, it disengages from the locking part 34, allowing the cup lid 3 to move to the second position to release the limiting cavity.

[0044] A second elastic element 41 is provided inside the mounting cavity. In this embodiment, the second elastic element 41 is a helical compression spring sleeved on the guide post, and its direction of action is consistent with that of the guide post. It is used to apply a thrust to the locking member 4 to move it toward the locking position, thereby ensuring that the locking member 4 and the locking part 34 can be reliably engaged. In other embodiments, the second elastic element 41 can also be a leaf spring, a rubber elastic element, etc.

[0045] To facilitate the release of the locking element 4 from the locking part, an unlocking element 42 is also provided on the handle. The unlocking element 42 is connected to the locking element 4. When the user operates the unlocking element 42, the unlocking element 42 drives the locking element 4 to overcome the elastic force of the second elastic element 41 and return to the unlocked position, disengaging from the locking part 34, thereby releasing the locking engagement. At this time, the cup lid 3 automatically flips to the second position under the action of the torsion spring, disconnecting the motor circuit and releasing the limiting cavity, allowing the user to safely remove the cup from the base.

[0046] Through the above design, during the operation of the drive motor 11, the cup lid 3 remains in the first position and, together with the base 1 and the support arm 12, forms a limiting cavity, reliably restricting the cup body 2 onto the base 1, preventing the user from removing it. Only when the user operates the unlocking component 42, causing the cup lid 3 to deviate from the first position, and the circuit of the drive motor 11 is cut off, can the limiting cavity be released, allowing the cup body 2 to be removed from the base 1. This achieves the safety logic of "cup can only be removed after the machine is stopped," effectively avoiding the safety hazards caused by the "cup can only be removed before power is cut off" logic in the prior art, and improving the safety of user operation. Example 2

[0047] This embodiment provides a modular food processor, whose structure is largely the same as that of Embodiment 1, including a base 1, a cup body 2, and a lid 3 (not shown). (See reference...) Figure 5 Unlike Embodiment 1, in this embodiment, the pivot 31 is arranged vertically, allowing the cup lid 2 to rotate around the pivot 31 in a plane between a first position and a second position. The first position is when the cup lid 3 covers and closes the mouth of the cup body 2, and the second position is when the cup lid 3 is rotated to a position away from the mouth of the cup body 2.

[0048] In this embodiment, the position detection element 121 is a magnetic switch, and the trigger part 33 is a magnet. When the cup lid 3 is in the first position, the magnet approaches the magnetic switch, the motor circuit is closed, and the drive motor 11 can run when the user operates the control switch on the base. Once the cup lid 3 begins to deviate from the first position, the magnet gradually moves away from the magnetic switch, the motor circuit is disconnected, and the drive motor 11 cannot run even if the user operates the control switch. Specifically, the magnetic switch can be a Hall sensor or a reed switch.

[0049] The remaining structure and working principle are the same as in Example 1, and will not be repeated here. Example 3

[0050] refer to Figure 6 This embodiment provides a split-type food processor, whose structure is largely the same as that of Embodiment 1, including a base 1, a cup body 2, and a lid 3. Unlike Embodiment 1, in this embodiment, the support arm 12 is provided with a guide rail 122, and the lid 3 is arranged on the guide rail 122, allowing the lid 3 to slide relative to the support arm 12 between a first position and a second position. The first position is when the lid 3 slides down and covers and closes the opening of the cup body 2; the second position is when the lid 3 moves upwards to a position away from the opening of the cup body 2.

[0051] In this embodiment, the first elastic element is a helical compression spring (not shown) arranged on the guide rail 122, with its axis arranged along the direction of the guide rail 122. It applies an elastic force to the cup lid 3 to make it slide toward the second position, so that when it is not locked, the cup lid 3 can automatically move up to the second position.

[0052] Furthermore, in this embodiment, the position detection element 121 is an induction coil, and the trigger part 33 is a magnet. When the cup lid 3 is in the first position, the magnet approaches the induction coil, and the induction coil outputs a signal to close the motor circuit; once the cup lid 3 begins to deviate from the first position, the magnet gradually moves away from the induction coil, the induction signal disappears, and the motor circuit is disconnected.

[0053] In this embodiment, the mechanical locking structure is basically the same as in Embodiment 1, except that the locking member 4 is disposed in the mounting cavity of the support arm 12 and cooperates with the locking part 34 on the cup lid 3. Correspondingly, the unlocking member 42 is also disposed on the support arm 12, which is used to drive the locking member 4 to overcome the elastic force of the second elastic member 41 and exit the cooperating position when the user operates, so that the cup lid 3 can deviate from the first position.

[0054] The remaining structure and working principle are the same as in Example 1, and will not be repeated here.

[0055] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
