Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing, specifically to a locking structure for a detachable blade assembly of a juicer. Background Technology
[0002] With increasing attention to healthy eating, juicers (also known as blenders, high-speed blenders, etc.) are widely used in both home and commercial settings. The core components of a juicer are the blade assembly and transmission mechanism. A motor drives the transmission mechanism to rotate the blades at high speed, cutting and crushing fruits, vegetables, and other ingredients to extract juice.
[0003] Most juicers currently on the market have non-removable blade components. A few juicers come with blade components bolted on at the factory, making it difficult for users to disassemble and reassemble them themselves. This also makes it difficult to thoroughly clean the entire appliance when cleaning is needed, thus reducing the user experience. Utility Model Content
[0004] The purpose of this invention is to provide a locking structure for the detachable blade assembly of a juicer that is easy for users to disassemble themselves.
[0005] The above objectives are achieved in this way.
[0006] A locking structure for a detachable blade assembly of a juicer includes a transmission component and a blade assembly. The top end of the transmission component is inserted into the blade assembly, and the two are connected in a transmission manner in the circumferential direction. The top end of the transmission component is provided with a wedge block and a spring, and the side wall of the top end of the transmission component is provided with a wedge block through hole. Under the action of the spring, the outer end of the wedge block passes through the wedge block through hole.
[0007] It also includes a locking cap, which is located in the tool assembly and can move up and down in the tool assembly. The inner diameter of the locking cap is about the same as the inner diameter of the upper end of the transmission component. When the transmission component and the tool assembly are engaged, the top end of the transmission component can be inserted into the locking cap, and the outer end of the wedge block that passes through the wedge block hole is locked between the bottom end of the tool assembly and the locking cap, so that the tool assembly cannot be disengaged from the top end of the transmission component when rotating.
[0008] When the locking cap is pressed down, it moves downward, and the inner wall of the locking cap forces the outer end of the wedge block to retract into the wedge block hole. The knife assembly and the locking cap can be pulled out of the transmission component at the same time.
[0009] The objective of this utility model can also be optimized by the following technical measures.
[0010] Preferably, there is an axial movement gap between the locking cap and the blade assembly. The locking cap can move freely up and down within the movement gap. When the transmission component and the blade assembly are engaged, the locking cap is lifted up, the outer end of the wedge block is unlocked, and the outer end of the wedge block is springed into the gap by the spring force to fill the gap. At this time, the blade assembly is locked.
[0011] Preferably, two wedge-shaped blocks are provided symmetrically, and the outer end of each wedge-shaped block is provided with an inclined surface.
[0012] Preferably, the locking cap end face is provided with a hook, and the knife assembly is provided with a hook groove corresponding to the hook. The hook is hooked into the hook groove to limit the locking cap in the circumferential direction, and the hook cannot be disengaged from the hook groove.
[0013] Preferably, it also includes a locking screw. The transmission component has a thread. When the transmission component and the blade assembly are engaged, the locking screw is inserted into the blade assembly and threadedly connected, so that the blade assembly cannot detach from the top of the transmission component when rotating.
[0014] By adopting the above technical solution, this utility model allows users to disassemble the knife assembly by pressing the locking cap, which is convenient and quick. Furthermore, the locking cap is fixed on the knife assembly, preventing the problem of losing the locking cap and thus being unable to lock the knife assembly. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] The first embodiment of this utility model, combined with Figures 1 to 3 A locking structure for a detachable blade assembly 1 of a juicer includes a transmission component 2 and a blade assembly 1. The top end of the transmission component 2 is inserted into the blade assembly 1, and the two are connected in a transmission manner in the circumferential direction. The top end of the transmission component 2 is provided with a wedge block 21 and a spring 22. The side wall of the top end of the transmission component 2 is provided with a wedge block through hole 20. Under the action of the spring 22, the outer end of the wedge block 21 passes through the wedge block through hole 20. Two wedge blocks 21 are symmetrically provided, and the outer end of the wedge block 21 is provided with a slope.
[0027] Combination Figure 8 It also includes a locking cap 3, the end face of which is provided with a hook 31, which is combined with Figure 7 The knife assembly 1 has a hook groove 11 corresponding to the hook 31. The hook 31 hooks into the hook groove 11, limiting the locking cap 3 in the circumferential direction, and the hook 31 cannot disengage from the hook groove 11. The hook groove 11 has a movement gap in the axial direction, combined with... Figures 4 to 6 This is manifested in that there is an axial gap 111 between the locking cap 3 and the blade assembly 1. The locking cap 3 can move freely up and down in the blade assembly 1. The inner diameter of the locking cap 3 is about the same as the inner diameter of the upper end of the transmission component 2. When the transmission component 2 and the blade assembly 1 are engaged, the top end of the transmission component 2 can be inserted into the locking cap 3. When the locking cap 3 is lifted up, the outer end of the wedge block 21 is unlocked. The height of the outer end of the wedge block 21 corresponds to the height of the moving gap. The outer end of the wedge block 21 that passes through the wedge block through hole 20 is springed into the gap 111 by the spring force of the spring 22, filling the gap so that the blade assembly 1 cannot be disengaged from the top end of the transmission component 2 when rotating.
[0028] Combination Figure 6 When the locking cap 3 is pressed down, the locking cap 3 moves downward, and the inner wall of the locking cap 3 forces the outer end of the wedge block 21 to retract into the through hole 20 of the wedge block 21, the knife assembly 1 is unlocked, and the knife assembly 1 and the locking cap 3 can be pulled out of the transmission component 2 at the same time.
[0029] The second embodiment of this utility model, combined with Figures 9 to 10 It includes a transmission component 2, a blade assembly 1, and a locking screw 4. The transmission component 2 is provided with threads. When the transmission component 2 and the blade assembly 1 are engaged, the locking screw 4 is inserted into the transmission component 2 and threadedly connected, so that the blade assembly 1 cannot detach from the top of the transmission component 2 when rotating.
