Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a capsule coffee machine. Background Art

[0002] A coffee machine is a device that makes it easy to make coffee. With the development of society, coffee machines are becoming increasingly popular. A capsule coffee machine is a type of coffee machine. To operate the machine, place a coffee capsule into the brewing base within the brewing rack to extract coffee with one click. Traditional, commonly used capsule coffee machines require manual insertion of the coffee capsule each time you brew. The general operation process is as follows: first open the inlet lid, place the coffee capsule on the brewing head, close the lid, then turn the drive handle to push the brewing head toward the brewing base until the coffee capsule is placed into the brewing base. Then, press the switch to extract the coffee. It's very convenient to use.

[0003] Please refer to the brewer and capsule coffee machine disclosed in the authorization announcement number CN103876624B. The brewer includes a fixed brewing seat and a brewing head that moves relative to the brewing seat. The brewing head is provided with a clamping mechanism for clamping the coffee capsule so that the brewing head moves synchronously when it moves toward the brewing seat. The clamping mechanism includes a capsule holder, and the capsule holder includes a drag head and a connecting rod. A shoulder is provided on the brewing seat. Through the cooperation of the shoulder and the capsule holder, the capsule holder is pushed open by the shoulder so that the capsule holder rotates outward to release the capsule, and a gap is left between the drag head and the brewing head so that the capsule can automatically fall when it returns. The cooperation between this type of capsule holder and the shoulder has certain defects: the capsule holder is constantly pushed outward and rotated by the shoulder. After the coffee capsule enters the brewing seat, due to the certain distance between the outer diameter and the inner diameter of the brewing seat, the edge of the coffee capsule is very small and exposed on the outer periphery of the brewing seat. When the capsule holder moves away from the brewing seat along the shoulder with the brewing head, the force of the drag head to push the coffee capsule is insufficient, which easily causes the coffee capsule to fail to smoothly leave the brewing seat. Summary of the Invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a capsule coffee machine which facilitates the smooth separation of the coffee capsule from the brewing seat.

[0005] In order to achieve the above-mentioned object, the present invention is designed to provide a capsule coffee machine, which includes a brewing mechanism, the brewing mechanism including a brewing bracket, an inlet and an outlet correspondingly opened on the brewing bracket, a brewing seat fixed in the brewing bracket, a brewing head slidably arranged in the brewing bracket, and a driving handle for driving the brewing head to move relative to the brewing seat, a pair of capsule holders are hingedly connected to the outer periphery of the brewing head, the capsule holder includes a connecting rod and a drag head, a gap is formed between the drag head and the brewing head, the drag head is located at one end of the gap as an abutment end, and a capsule slot for clamping coffee capsules is provided on the opposite side of the drag head, and the capsule holder can move closer to or away from the brewing seat as the brewing head moves closer to or away from the brewing seat;

[0006] A pair of shoulders is provided on the outer periphery of the brewing seat, the shoulders including a first lifting portion, a second lifting portion and a recovery portion, the first lifting portion, the second lifting portion and the recovery portion are a pair, the first lifting portion is connected to the recovery portion and is located on both outer sides of the pair of the second lifting portions, and the first lifting portion is closer to the brewing head than the second lifting portion;

[0007] The capsule holder approaches the brewing seat along the brewing head, and when the capsule holder slides along the first lifting part, the capsule holder is pushed open by the first lifting part and rotated outwards to allow the coffee capsule to disengage from the capsule slot and completely enter the brewing seat; when the capsule holder slides along the recovery part, the capsule holder can rotate inwards along with the recovery part and allow the edge of the coffee capsule to be located in the gap; when the capsule holder slides along the second lifting part, the capsule holder is pushed open by the second lifting part and rotated outwards until the needle on the brewing head pierces the coffee capsule; when the capsule holder moves away from the brewing seat along the brewing head, the capsule holder slides into the recovery part along the second lifting part in sequence, and the abutting end pushes the edge of the coffee capsule to disengage from the brewing seat until the coffee capsule disengages from the brewing seat and falls down into the outlet.

[0049] The following is a detailed description of a capsule coffee machine of the present invention in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0050] Please refer to Figures 1 to 25 As shown, the present application provides a capsule coffee machine, which includes a brewing mechanism 100, the brewing mechanism 100 includes a brewing support 110, a receiving cavity 111 provided in the brewing support 110, an inlet 112 and an outlet 113 correspondingly opened on the brewing support 110 and connected to the receiving cavity 111, a brewing seat 120 fixed in the receiving cavity 111, a brewing head 130 slidably provided in the receiving cavity 111, and a driving handle 140 for driving the brewing head 130 to move linearly relative to the brewing seat 120.

[0051] The coffee capsule 200 is placed on the brewing head 130 through the inlet 112, and then the driving handle 140 is rotated. The driving handle 140 drives the brewing head 130 to approach the brewing seat 120 in a horizontal straight line, thereby pushing the coffee capsule 200 into the brewing seat 120. Then, the switch is pressed to brew and extract coffee. The pushing process, brewing and extraction method, the brewing support 110, the brewing seat 120, the driving handle 140 and the brewing head 130 are the same as those in the prior art and will not be repeated here.

[0052] A pair of capsule holders 150 are hingedly connected to the outer periphery of the brewing head 130. The capsule holder 150 includes a connecting rod 151 and a drag head 152. A gap 160 is formed between the drag head 152 and the brewing head 130. One end of the drag head 152 located at the gap 160 is an abutment end 153. A capsule slot 154 for clamping the coffee capsule 200 is provided on the opposite side of the drag head 152. The capsule holder 150 can move closer to or away from the brewing seat 120 as the brewing head 130 approaches, and can deliver the coffee capsule 200 into and out of the brewing seat 120.

[0053] A pair of shoulders are provided on the outer periphery of the brewing seat 120, and the shoulders include a first lifting portion, a second lifting portion and a recovery portion. The first lifting portion, the second lifting portion and the recovery portion are a pair. The first lifting portion is connected to the recovery portion and is located on both outer sides of a pair of the second lifting portions. The first lifting portion is closer to the brewing head 130 than the second lifting portion and the recovery portion.

[0054] The capsule holder 150 approaches the brewing seat 120 along with the brewing head 130. When the capsule holder 150 slides along the first lifting portion, the capsule holder 150 is pushed open by the first lifting portion and rotated outwards to allow the coffee capsule 200 to escape from the capsule slot 154 and completely enter the brewing seat 120. When the capsule holder 150 continues to slide along the recovery portion, the capsule holder 150 can rotate inwards along the recovery portion and allow the edge 210 of the coffee capsule 200 to be located in the gap 160. When the capsule holder 150 slides along the second lifting portion, the capsule holder 150 is pushed open by the second lifting portion. The capsule holder 150 is rotated outward until the needle on the brewing head 130 pierces the coffee capsule 200. When the capsule holder 150 moves away from the brewing seat 120 along with the brewing head 130, the capsule holder 150 slides into the recovery portion along the second lifting portion in sequence. When the abutting end 153 slides on the recovery portion, it abuts against the edge 210 of the coffee capsule 200 to push the coffee capsule 200 away from the brewing seat 120. The capsule holder 150 continues to move away from the brewing seat 120 along with the brewing head 130 until the coffee capsule 200 moves away from the brewing seat 120 and then falls downward into and passes through the outlet 113.

[0055] During the movement of the brewing head 130 away from the brewing seat 120, the drag head 152 will obtain a certain acceleration force from the second lifting portion to the recovery portion, and the force of the abutting end 153 pushing the edge 210 of the coffee capsule 200 will be strengthened, which is conducive to pushing the coffee capsule 200 away from the brewing seat 120.

[0056] Specifically, the first lifting portion includes a first guide slope 121 and a top opening slope 122 arranged in sequence, and the recovery portion includes a recovery slope 123, and the recovery slope 123 is connected to the top opening slope 122. The first guide slope 121 is closer to the brewing head 130 than the top opening slope 122, and the distance between the first guide slope 121 and the axis of the brewing seat 120 gradually increases from the end away from the top opening slope 122 to the end close to the top opening slope 122. The distance between the top opening slope 122 and the axis of the brewing seat 120 gradually increases from the end close to the first guide slope 121 to the end away from the first guide slope 121. The distance between the recovery slope 123 and the axis of the brewing seat 120 gradually decreases from the end close to the top opening slope 122 to the end away from the top opening slope 122.

[0057] The second lifting portion includes a lifting end surface 124 , and the distance between the lifting end surface 124 and the axis of the brewing seat 120 gradually increases from an end close to the brewing head 130 to an end away from the brewing head 130 .

[0058] The first guide slope 121, the top opening slope 122 and the restoration slope 123 on the same shoulder are connected in sequence, and a pair of the top end surfaces 124 are arranged between a pair of the first top parts and the restoration parts, and a limiting space 125 is formed between the first top parts and the restoration parts on the same shoulder, and the top end surface 124 is arranged in the limiting space 125.

[0059] The drag head 152 includes a main body 155 and guide parts 156 provided on both sides of the main body 155, the guide parts 156 are adapted to the first lifting part and the recovery part, the main body 155 is provided with the capsule groove 154, when the capsule holder 150 slides along the shoulder, the main body 155 is slid into the limiting space 125, and the main body 155 is adapted to the second lifting part.

[0060] In this embodiment, the guide portion 156 includes a guide arc surface 1561, a sliding inclined surface 1562 and an adapting inclined surface 1563 arranged in sequence, the first guide inclined surface 121 is adapted to the guide arc surface 1561, and the restoring inclined surface 123 is adapted to the adapting inclined surface 1563, wherein the first guide arc surfaces 1561 between the guide portions 156 are connected to each other, that is, the first guide arc surface 1561 is also provided on the main body 155.

[0061] The main body 155 is provided with a second guiding inclined surface 1551 , which is matched with the lifting end surface 124 . The capsule groove 154 is provided between the second guiding inclined surface 1551 and the abutting end 153 .

[0062] The angle at which the capsule holder 150 is pushed outward by the first lifting portion is smaller than the angle at which the capsule holder 150 is pushed outward by the second lifting portion. In this embodiment, the angle at which the capsule holder 150 is pushed outward by the first lifting portion is 1°, while the angle at which the capsule holder 150 is pushed outward by the second lifting portion is 6°. This configuration is intended to provide greater acceleration force after the capsule holder 150 slides along the second lifting portion to the recovery portion, thereby further facilitating the removal of the coffee capsule 200 from the brewing base 120.

[0063] In this embodiment, a pair of guide grooves 114 are provided in the receiving cavity 111 of the brewing bracket 110, and a pair of pressure blocks 170 are fixedly provided on the periphery of the brewing head 120, and the pressure blocks 170 are adapted to the guide grooves 114. One end of the connecting rod 151 is hinged between the brewing head 120 and the pressure blocks 170, and an elastic member is provided between the connecting rod 151 and the pressure blocks 170, and the elastic member is a spring.

[0064] The driving handle 140 is connected to the brewing head 120 via a transmission member 180. The transmission member 180 includes a handle connecting rod 181 and a connecting rod assembly 182 that are hinged to each other. The handle connecting rod 181 is fixedly connected to the driving handle 140. The connecting rod assembly 182 includes a first connecting rod 1821, a second connecting rod 1822, and a third connecting rod 1823 that are hinged to each other in sequence. The first connecting rod 1821 is hinged to the handle connecting rod 181, and the third connecting rod 1823 is hinged to the brewing head 120.

[0065] In this embodiment, the handle connecting rod 181 is connected to the gear connecting rod 190 by meshing teeth. Specifically, the handle connecting rod 181 is provided with first sector-shaped teeth 1811, and the gear connecting rod 190 is provided with second sector-shaped teeth 191. The first sector-shaped teeth 1811 mesh with the second sector-shaped teeth 191. The tooth coordination between the first sector-shaped teeth 1811 and the second sector-shaped teeth 191 can improve the user's experience of rotating the drive handle 140, effectively limit the rotation of the drive handle 140, and extend the service life of the capsule coffee machine.

[0066] In this embodiment, a limiting protrusion 1824 is provided on the third connecting rod 1823, and the limiting protrusion 1824 rotates synchronously with the third connecting rod 1823. When the brewing head 130 moves toward the brewing seat 120, the upper wall of the accommodating cavity 111 is arranged on the rotation track of the limiting protrusion 1824. Such a setting can not only limit the movement of the brewing head 130 and the driving handle 140, but also prevent the brewing head 130 from moving away from the brewing seat 120 during the brewing and extraction process, which is conducive to controlling the movement of the brewing head 130.

[0067] When the driving handle 140 is in a fully open state, the brewing head 130 is away from the brewing seat 20, and a space vertically connected to the inlet 112 and the outlet 113 is formed between the brewing head 130 and the brewing seat 120. The coffee capsule 200 is put into the inlet 112, and the edge 210 of the coffee capsule 200 is stuck in the capsule slot 154. Then, the driving handle 140 is pressed downward counterclockwise, and the driving handle 140 drives the handle connecting rod 181 to rotate. The first sector teeth 1811 on the handle connecting rod 181 drive the second sector teeth 1191 to rotate, and the handle connecting rod 181 is rotated. The rod 181 drives the first connecting rod 1821 to rotate, the first connecting rod 1821 drives the second connecting rod 1822 to rotate, the second connecting rod 1822 drives the third connecting rod 1823 to rotate, the rotation of the third connecting rod 1823 drives the brewing head 130 to approach the brewing seat 120, and the capsule holder 150 drives the coffee capsule 200 to approach the brewing seat 120 along with the brewing head 130. When the guide arc surface 1561 contacts the first guide inclined surface 121, the capsule holder 150 starts to rotate outward, the coffee capsule 200 has been partially and continues to be slowly inserted into the brewing seat 120, and the brewing The brewing head 2 continues to approach the brewing seat 120, and the sliding slope 1562 is slidably arranged on the top opening slope 122. The capsule holder 150 continues to rotate outward under the action of the top opening slope 122, and the coffee capsule 200 continues to be inserted into the brewing seat 120. When the sliding slope 1562 slides to the top of the top opening slope 122, the coffee capsule 200 is completely inserted into the brewing seat 120. After the brewing head 130 continues to approach the brewing seat 120 and moves a little distance, the drag head 152 is completely located at the front end of the edge 210, that is, the abutting end 153 is farther away from the brewing head 130 than the edge 2101. 30, the coffee capsule 200 is arranged in the brewing seat 120, and under the cooperation of the adapting inclined surface 1563 and the restoring inclined surface 123, the capsule holder 150 rotates inward. At this time, the brewing head 130 continues to move toward the brewing seat 120. Under the cooperation of the lifting end surface 124 and the second guide inclined surface 1551, the capsule holder 150 rotates outward again. At this time, the needle on the brewing head 130 pierces the coffee capsule 200. At this time, the driving handle 140 is in a fully closed state, and the limiting protrusion 1824 abuts against the upper wall of the receiving chamber 111. Then, the switch is pressed to brew and extract coffee.

[0068] After the brewing and extraction of coffee is completed, the driving handle 140 is rotated in the opposite direction, and the driving handle 140 drives the handle connecting rod 181 and the connecting rod assembly 182 in turn to drive the brewing head 130 away from the brewing seat 120, and the capsule holder 150 moves synchronously with the brewing head 130, and the capsule holder 150 moves in the opposite direction along the top end surface 124, and the capsule holder 150 rotates inward. When the drag head 152 moves in the opposite direction along the recovery slope 123, the capsule holder 150 rotates outward. When it moves to a certain distance, the capsule holder 150 rotates outward. The abutting end 153 abuts against the edge 210 and pushes the coffee capsule 200 to move away from the brewing seat 120. The capsule holder 150 continues to move along the recovery slope 123 and the first lifting portion until the coffee capsule 200 is completely separated from the brewing seat 120. Since the edge 210 is located in the gap 160, the coffee capsule 200 falls down out of the outlet 113 under its own gravity, and then the driving handle 140 is driven to be fully opened, waiting for the next coffee brewing and extraction.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
