Description

Bean grinder

Technical Field

The utility model relates to a technical field of life electrical apparatus, concretely relates to bean grinder.

Background

Grind beans machine is a life electrical apparatus of taking stirring function, and during operation rabbling mechanism 3a can high-speed rotation, consequently for safe in utilization, grind beans machine during operation must cover bowl cover 2a, and present mill beans machine has appeared must cover the technique that bowl cover 2a ground beans machine could normally work, and its concrete structure is as follows:

as shown in fig. 1, the bottom of the cup lid 2a is connected with a support 5a, the support 5a can be reset through an elastic resetting device 6a, a control switch 4a electrically connected with the stirring mechanism 3a is arranged on the support 5a, and the control switch 4a can reciprocate up and down along with the support 5 a.

After the cup cover 2a is covered, the cup cover 2a presses the support 5a, the elastic resetting device 6a stores energy, the elastic contact 41a of the control switch 4a moves to a position corresponding to the switch button 7a, and the control switch 4a can be conducted by pressing the switch button 7a, so that the stirring mechanism 3a can work normally.

When the cup cover 2a is not covered, the support 5a resets under the action of the elastic resetting device 6a and drives the control switch 4a to move upwards synchronously, so that the elastic contact 41a of the control switch 4a leaves the position corresponding to the switch button 7a, and the control switch 4a cannot be conducted by pressing the switch button 7a at the moment, so that the stirring mechanism 3a is prevented from working under the state that the cup cover 2a is not covered.

However, the structure still has a potential safety hazard, when the user covers the cup cover 2a and normally triggers the control switch 4a to conduct through the switch button 7a, so that after the stirring mechanism 3a starts to work, if the pressure d1 borne by the switch button 7a is too large (such as the pressure of the hand of the user is too large, or the switch button 7a is stuck), the pressure d2 borne by the elastic contact 41a is equal to the pressure d1, the friction force between the switch button 7a and the elastic contact 41a is greater than the reset elastic force of the elastic reset device 6a, at this time, if the cup cover 2a is accidentally opened, the support 5a cannot be normally reset, the stirring mechanism 3a still continues to work, and safety accidents are easily caused.

Therefore, further improvements are needed.
