This application claims priority benefit from China Patent Application No. 201810214636.4, filed on Mar. 15, 2018, entitled “BEAN GRINDING COFFEE MAKER”, the entirety of which is incorporated by reference herein.
The present application relates to the field of electrical product for making coffee beverage, in particular to a bean grinding coffee maker.
A commercially available coffee maker provided with a bean grinding device has poor sealing performance at a powder outlet opening thereof, causing an introduce of steam into a chamber of the bean grinding device in cooking coffee and thus making the coffee powder to be damped. The damp coffee powder tends to be cohered together to form a block, resulting in a blockage of the coffee powder.
In order to address the sealing problem of the powder outlet opening, the current bean grinding coffee maker generally adopts a mechanism including a relatively large number of components and having a relatively complicated structure, thus having a high cost.
In view of the above, there is a need to provide a bean grinding coffee maker to address the powder blockage problem caused by the introduce of the steam into the chamber of the bean grinding device due to the poor sealing performance of the powder outlet opening of the bean grinding coffee maker in the prior art.

The first sealing ring support is tightly sleeved between the inner ring and the outer ring. The inner ring is tightly clamped between an outer wall of the powder outlet passage and an inner wall of the first sealing ring support. The outer ring is tightly clamped between the upper body of the machine body and an outer wall of the first sealing ring support. The blocking plate presses against the sealing portion to seal and close the powder outlet passage.
In an embodiment, the sealing portion is in a shape of a downward-convex curved surface.
In an embodiment, the sealing portion is in a shape of an arched spherical surface.
In an embodiment, the sealing component further includes a second sealing ring support sleeved on an inner side wall of the inner ring and tightly abutting against the outer wall of the powder outlet passage.
In an embodiment, a protruding step is provided on the inner side wall of the inner ring and adjacent to the sealing portion. A bottom of the second sealing ring support abuts against the protruding step.
In an embodiment, the bean grinding coffee maker further includes a motor support and a microswitch. The motor support is arranged on an upper body of the machine body. The driving motor is fixed on the motor support. The microswitch is arranged on the motor support to control the motor to rotate.
In an embodiment, the brewing device further includes a coffee basket for containing coffee powder. The coffee basket is located under or beside the power outlet opening.
In the above-described bean grinding coffee maker, the sealing component is provided at the end opening of the powder outlet passage; the blocking plate is provided between the sealing component and the brewing device; and the blocking plate is staggered with or presses against the bottom of the sealing component by means of moving, so as to control the powder outlet passage to be communicated with or isolated from the brewing device, thereby achieving the excellent seal of the powder outlet opening, and overcoming the powder blockage defect caused by the steam introduced into the bean grinding chamber due to the poor sealing performance of the powder outlet opening of the bean grinding coffee maker in the prior art. The effective sealing of the powder outlet opening is achieved, and moreover, the characteristics of simple and reasonable structure, automation, high sealing performance, simple operation, low cost, and so on are obtained.

Referring to
Specifically, the machine body 10 includes an upper body and a lower body. The coffee bean grinding device 100 is arranged in the upper body 10 to grind the coffee bean. The powder outlet passage 110 is disposed at the bottom of the coffee bean grinding device 100. After the coffee beans are ground into granules or powder, the granules or the powder enter the brewing device 200 disposed under the powder outlet passage 110 through the powder outlet passage 110 to be soaked.
Specifically, the brewing device 200 includes a coffee basket located under or beside the power outlet opening. The coffee basket is configured to contain the coffee powder discharged from the powder outlet passage 110. The coffee powder is soaked in the coffee basket.
Specifically, the blocking plate 400 is disposed between the sealing component 300 and the brewing device 200. The blocking plate 400 has two operating positions. In a first operating position, the blocking plate 400 is staggered with the bottom of the sealing component 300; the coffee bean grinding device 100 is in communication with the brewing device 200 through the powder outlet passage 110; and the coffee power in the coffee bean grinding device 100 enters the brewing device 200, specifically, the coffee basket. In a second operating position, the blocking plate 400 presses against the bottom of the sealing component 300; the end opening of the powder outlet passage 110 is blocked and closed; and the coffee bean grinding device 100 is sealed and isolated from the brewing device 200. The steam in the brewing device 200 is blocked by the blocking plate 400 and cannot enter the coffee bean grinding device 100, overcoming the powder blockage defect caused by the steam introduced into the bean grinding chamber due to the poor sealing performance of the powder outlet opening. Therefore, the effective sealing of the powder outlet opening is achieved, and moreover, the characteristics of simple and reasonable structure, automation, high sealing performance, simple operation, low cost, and so on are obtained.

In an embodiment, the brewing device 200 further includes a coffee basket for containing the coffee powder. The coffee basket is located under or beside the power outlet opening. The coffee basket is configured to contain the coffee powder discharged from the powder outlet passage 110. The coffee powder is soaked in the coffee basket.
The operating principle of the bean grinding coffee maker is as follows.
The microswitch 520 controls the driving motor 500 to rotate, and the driving motor 500 drives the blocking plate 400 to make a translational movement. When the blocking plate 400 is staggered with the end opening of the powder outlet passage 110, the coffee bean grinding device 100 is in communication with the brewing device 200 through the powder outlet passage 110, and the coffee powder in the coffee bean grinding device 100 enters the brewing device 200, specifically, the coffee basket. When the blocking plate 400 presses against the sealing portion 333 of the sealing component 300, the end opening of the powder outlet passage 110 is blocked and closed, and the coffee bean grinding device 100 is sealed and isolated from the brewing device 200.
In the above-described bean grinding coffee maker, the sealing component 300 is provided at the end opening of the powder outlet passage 110; the blocking plate 400 is provided between the sealing component 300 and the brewing device 200; the blocking plate 400 is staggered with or presses against the bottom of the sealing component 300 by means of moving, so as to control the powder outlet passage 110 to be communicated with or isolated from the brewing device 200, thereby achieving the excellent seal of the powder outlet opening, and overcoming the powder blockage defect caused by the steam introduced into the bean grinding chamber due to the poor sealing performance of the powder outlet opening of the bean grinding coffee maker in the prior art. The effective sealing of the powder outlet opening is achieved, and moreover, the characteristics of simple and reasonable structure, automation, high sealing performance, simple operation, low cost, and so on are obtained.
