Description

Technical Field

[0001] This utility model relates to the field of blenders, specifically to a blade holder anti-fall-off device. Background Technology

[0002] When using a high-speed blender, the blade holder and cup holder often accidentally detach. This not only interrupts the normal operation of the machine but can also cause the high-speed rotating blades to suddenly pop out, causing direct physical injury to the user. Such problems significantly reduce the user experience and ease of operation; more importantly, they pose a significant personal safety hazard, exposing users to potential risks in daily use.

[0003] Traditional blade holder and cup holder connections are often overly simplistic, lacking scientifically sound anti-detachment mechanisms such as reliable snap-fit ​​structures, locking devices, or redundant fixing designs. Under conditions of high-speed operation generating severe vibrations, or external impacts, tilting, or even minor shocks, this connection method is highly susceptible to failure, leading to separation of the blade holder and cup holder. Once detached, the sharp blade may continue moving due to inertia, causing cuts, punctures, or other serious injuries to the user or those around them, and potentially triggering even more serious safety accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a knife holder anti-detachment device that ensures a stable connection between the knife holder and the cup holder.

[0005] The above objectives are achieved in this way.

[0006] A knife holder anti-dislodgement device includes a knife holder and a cup holder. The knife holder is disposed on the cup holder. A spring-loaded switch is provided at the bottom of the knife holder. A locking hole is provided on the cup holder corresponding to the spring-loaded switch. When the knife holder is installed on the cup holder, the spring-loaded switch is embedded and limited in the locking hole. In the installed state, pressing the knife holder down again unlocks the spring-loaded switch.

[0007] The objective of this utility model can also be optimized by the following technical measures.

[0008] Preferably, the bottom of the tool holder is provided with a connector, and the top of the spring switch is provided with a corresponding connection hole. When the spring switch is installed at the bottom of the tool holder, the connector is inserted and limited in the connection hole.

[0009] During the installation of the spring-loaded switch to the bottom of the tool holder, the fit between the connector and the connecting hole plays a crucial role in positioning and securing it. The shape and size of the connector match the connecting hole, ensuring that the spring-loaded switch can be accurately and stably installed at the bottom of the tool holder. Simultaneously, a limiting structure is provided inside the connecting hole to prevent the spring-loaded switch from loosening or falling off during use, thus ensuring the overall stability and reliability of the tool holder's anti-fall-off device.

[0010] Preferably, the number of spring-loaded switches corresponds to the number of keyholes, and the number of spring-loaded switches and latches is not less than two each.

[0011] Preferably, the top of the spring switch is provided with a limiting stop, and the lock hole is provided with a stepped surface. When the spring switch is installed in the lock hole, the limiting stop abuts against the stepped surface.

[0012] By adopting the above technical solution, this utility model uses a spring-loaded switch to lock the spring-loaded push-button switch onto the cup holder. The knife holder has a special structure that allows it to be securely locked onto the cup holder when a certain pressure is applied and pressed down, preventing it from falling off; if pressed down again, the knife holder will loosen and can then be removed.

[0013] This design ensures a secure yet easy-to-disassemble connection between the blade holder and the cup holder. In practical use, users only need to press the blade holder firmly to achieve this connection, eliminating concerns about accidental detachment during use. Similarly, to disassemble the blade holder, simply press down again to easily release it, greatly simplifying the user experience. Furthermore, the device incorporates multiple spring-loaded switches and locking holes to further enhance the stability of the connection between the blade holder and the cup holder, thus ensuring safety during use.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] A device for preventing a knife holder 3 from falling off includes a knife holder 3 and a cup holder 2. The knife holder 3 is mounted on the cup holder 2. A spring-loaded switch 4 is provided at the bottom of the knife holder 3. A locking hole 21 is provided at the cup holder 2 corresponding to the spring-loaded switch 4. When the knife holder 3 is installed on the cup holder 2, the spring-loaded switch 4 is embedded and limited in the locking hole 21. In the installed state, pressing the knife holder 3 down again unlocks the spring-loaded switch 4.

[0023] The bottom of the blade holder 3 is provided with a connector 31, and the top of the spring switch 4 is provided with a corresponding connecting hole 41. When the spring switch 4 is installed to the bottom of the blade holder 3, the connector 31 is inserted into and limited in the connecting hole 41. During the process of installing the blade holder 3 to the cup holder 2, the connector 31 at the bottom of the blade holder 3 will also simultaneously align with the connecting hole 41 at the top of the spring switch 4. After being subjected to a certain pressure, the connector 31 will be inserted into the connecting hole 41, and the fit between the connector 31 and the connecting hole 41 is tight. In this embodiment, the shape of the connector 31 is approximately thumbtack-shaped. The protruding structure on the connector 31 and the groove structure in the connecting hole 41 engage with each other, so that the spring switch 4 can be firmly installed to the bottom of the blade holder 3 and will not loosen or fall off during use.

[0024] The number of spring-loaded switches 4 corresponds to the number of keyholes 21, and there are at least two spring-loaded switches 4 and at least two keyholes 21 each. Because the number of spring-loaded switches 4 and keyholes 21 corresponds and there are at least two keyholes 21 each, this multi-point connection method greatly enhances the stability of the connection between the knife holder 3 and the cup holder 2. In actual use, even if one spring-loaded switch 4 is slightly loosened by abnormal external force, the other spring-loaded switches 4 can still maintain normal operation, ensuring that the knife holder 3 will not fall off the cup holder 2, effectively guaranteeing the safety of use. In this embodiment, there are four spring-loaded switches 4 and four keyholes 21, effectively ensuring the normal operation of the structure.

[0025] The spring switch 4 has a limiting stop 42 at its top, and the lock hole 21 has a stepped surface 22. When the spring switch 4 is installed in the lock hole 21, the limiting stop 42 at the top of the spring switch 4 will abut against the stepped surface 22 in the lock hole 21. The limiting stop 42 has a certain strength and rigidity and can withstand a certain amount of pressure, while the stepped surface 22 provides a stable support surface for the limiting stop 42. This design allows the position of the spring switch 4 in the lock hole 21 to be precisely defined, preventing installation that is too deep or too shallow, further ensuring the accuracy and stability of the connection between the knife holder 3 and the cup holder 2. When it is necessary to disassemble the knife holder 3, press the knife holder 3 down again. The spring switch 4 deforms under pressure, the limiting stop 42 separates from the stepped surface 22, the spring switch 4 unlocks, and the knife holder 3 can then be easily removed from the cup holder 2.
