Description

Technical Field

[0001] The utility model belongs to the technical field of coffee machines, and in particular relates to a pressed powder extraction device for coffee machines. Background Art

[0002] The coffee maker also requires manual labor to prepare the coffee, which can cause the coffee powder to be squeezed out of the cup and then left to dry. Utility Model Content

[0003] (1) Purpose of the utility model

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a powder pressing and extraction device for a coffee machine, so as to solve the problems that the existing method of pressing powder by hand-held manual tools easily leads to uneven pressing of powder, which affects the taste of brewing, the coffee powder easily sticks to the manual tool and falls onto the table as the manual tool moves, which is not only wasteful but also easy to dirty the table, and the coffee machine performs powder pressing and extraction in two separate steps, which increases the user's hand movements, resulting in a longer time spent on making a cup of coffee and slow production efficiency. In addition, it is necessary to purchase manual tools separately, which increases the cost of use, and the manual tools are easily lost when placed alone, affecting the technical problems of coffee making.

[0005] (2) Technical solution

[0006] To achieve the above objectives, the technical solutions provided by this application are as follows:

[0007] A pressed powder extraction device for a coffee machine comprises: a bracket with a through hole formed in the middle thereof; a hinge pivotally disposed above the bracket, the hinge having a fixed end hingedly connected to the bracket and a free end; two guide grooves of an arcuate structure symmetrically formed on either side of the hinge along its length; a brewing head disposed between the bracket and the hinge, the brewing head being connected to an external water source; a guide shaft extending through the upper end of the brewing head and having its ends respectively embedded in the guide grooves; the guide shaft being capable of sliding along the guide grooves when the free end of the hinge swings downward, thereby driving the brewing head to move downward through the through hole and flatten coffee powder contained in a powder container below; wherein, after the coffee powder is flattened, the brewing head injects water into the powder container;

[0008] The present application adopts the powder pressing and extraction device of the above structure. When brewing coffee, the powder filling device filled with coffee powder is placed under the bracket, and then the hinge is driven to swing downward. As the hinge swings downward, the brewing head moves downward to flatten the coffee powder. Then, water is discharged from the brewing head to extract the coffee powder. The hinge drives the brewing head to press down as a whole to flatten the coffee powder, so that the coffee powder in the powder filling device is evenly stressed as a whole, thereby ensuring the powder pressing effect. In addition, the brewing head does not need to be taken out after compacting the powder, and water can be directly injected for extraction, thereby avoiding coffee powder adhesion and causing waste of coffee powder and dirtying the countertop. The brewing head has both the functions of compacting powder and discharging water for brewing. Powder compacting and extraction can be completed with only one action, thereby improving the efficiency of coffee brewing. There is no need to purchase a powder pressing hammer separately, and the cost of use is low. The brewing head is connected to the bracket and is not easy to lose.

[0009] In some embodiments, the guide groove is a J-shaped structure formed from the fixed end to the free end of the brewing head;

[0010] By optimizing the shape of the guide groove, when the hinge swings downward to the lowest position, the guide shaft just moves to the hook-shaped position at the end of the guide groove. The guide groove squeezes the guide shaft downward through the hook-shaped structure, applying uniform downward pressure to the entire brewing head to ensure the uniformity of the pressed powder.

[0011] In some embodiments, the guide groove is recessed inward at the end position near the free end to form an anti-dropping position;

[0012] An anti-slip position is set at the hook-shaped position of the guide groove to prevent the guide shaft from falling out from the hook-shaped position of the guide groove due to excessive force when pressing the coffee powder in the brewing head, thereby affecting the coffee pressing process.

[0013] In some embodiments, mounting grooves for engaging the edges of the powder filling device are respectively provided on both sides of the lower side of the bracket;

[0014] The installation groove is provided to facilitate the quick installation of the powder filling device on the bracket. After the powder filling device is installed, it is more stable when pressing powder in the brewing head, ensuring the uniformity of the pressed powder.

[0015] In some embodiments, the brewing head includes: a brewing head body with a water outlet at the bottom, and a water pipe inserted into the brewing head body and connected to a water source and the water outlet at both ends respectively.

[0016] In some embodiments, the invention further comprises: a sealing ring arranged on the outer side of the brewing head body and abutting against the inner side surface of the through hole;

[0017] The sealing ring can be provided to improve the sealing degree of the pressed powder extraction device, thereby preventing hot water from leaking from the gap between the brewing head and the inner side surface of the through hole when the water pipe is filled with water.

[0018] In some embodiments, the invention further comprises: a filter sheet arranged on the bottom surface of the lower end of the brewing head body.

[0019] In some embodiments, it also includes: a handle provided on one side of the hinge for driving the hinge to swing up and down. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0029] See also Figure 1-Figure 3 The utility model provides a pressed powder extraction device for a coffee machine, comprising: a bracket 1 with a through hole 101 in the middle, a hinge 4 swingably arranged above the bracket 1, the fixed end of the hinge 4 being hinged to the bracket 1, and the other end being a free end, two guide grooves 401 of an arc structure symmetrically provided on both sides of the hinge 4 along its length direction, a brewing head 2 arranged between the bracket 1 and the hinge 4 and connected to an external water source, a guide shaft 3 passing through the upper end of the brewing head 2 and with both ends respectively embedded in the guide grooves 401, capable of sliding along the guide grooves 401 when the free end of the hinge 4 swings downward, driving the brewing head 2 to move downward through the through hole 101 to flatten the coffee powder contained in the powder filling container 8 below, wherein after the coffee powder is flattened, the brewing head 2 injects water into the powder filling container 8.

[0030] See also Figure 3 Specifically, two symmetrical fixed walls 102 are formed on the upper end surface of the bracket 1, and the hinge 4 is hinged to the fixed wall 102 through the hinge shaft 7.

[0031] See also Figure 4 and Figure 5 Preferably, the present application provides a handle 6 on one side of the hinge 4, and the handle 6 can drive the hinge 4 to swing up and down on the bracket 1.

[0032] Specifically, when installing the brewing head 2, the guide shaft 3 passes through the circular hole opened on the top of the brewing head 2, and then passes through the guide groove 401 in the hinge 4 to realize the positioning rotation of the cylinder and the circular hole. When the hinge 4 swings, it can drive the brewing head 2 to move straight up or down.

[0033] Specifically, two mounting grooves 103 are respectively provided on both sides of the lower side of the bracket 1 for engaging the edges of the powder filling device 8 .

[0034] Specifically, the brew head 2 includes a brew head body 201 and a water pipe 5. The brew head body 201 has a water outlet at its bottom. The water pipe 5 is inserted into the brew head body 201 at a 90-degree angle, with one end connected to a water source and the other end passing through the interior of the brew head body 201 and connected to the water outlet. Specifically, the water source can be a water tank or an external water pipe 5.

[0035] Specifically, the present application sets a filter plate 203 at the bottom of the lower end of the brewing head body 201, which can ensure the flatness of the bottom of the brewing head body 201 and filter the coffee powder to prevent the coffee powder from being reversely flushed into the water pipe 5 during the water injection process and causing blockage of the water pipe 5.

[0036] Preferably, it further comprises: a sealing ring 202 arranged around the outside of the brewing head body 201 and abutting against the inner side of the through hole 101 to prevent hot water from seeping out from the gap between the brewing head 2 and the inner side of the through hole 101 when water is injected into the water pipe 5.

[0037] Specifically, the process of brewing coffee is as follows:

[0038] A certain amount of coffee powder is loaded into the powder loading device 8 for the first time;

[0039] Snap the edges of the powder filling device 8 filled with a certain amount of coffee powder into the two mounting grooves 103;

[0040] When the handle 6 is pressed down, the hinge shaft 7 rotates with the handle 6, driving the hinge 4 to swing downward. Since the guide groove 401 is an arc-shaped structure, when the hinge 4 swings downward, the guide shaft 3 is driven by the guide groove 401 to slide from the fixed end close to the brewing head 2 toward the free end of the brewing head 2, so that the brewing head 2 can move downward to flatten the coffee powder. After the coffee powder is squeezed to a certain extent at the bottom of the brewing head 2, the hinge 4 can no longer swing downward, and the brewing head 2 stops moving downward.

[0041] The water pipe 5 starts to inject hot water into the powder filling device 8 to extract the coffee powder, and the extracted coffee liquid flows out from the liquid outlet at the bottom of the powder filling device 8.

[0042] Specifically, the present application sets the guide groove 401 into a J-shaped structure, which bends from the fixed end of the brewing head 2 to the free end. Specifically, a hook-shaped structure is formed near the free end of the brewing head 2. When the hinge 4 swings to the bottom, the guide shaft 3 just moves to the position of the hook-shaped structure. The hook-shaped structure can apply pressure downward to the guide shaft 3, and the guide shaft 3 then applies pressure to the punching head to squeeze the coffee powder (such as Figure 5 shown).

[0043] See also Figure 5 and Figure 6 Preferably, the guide groove 401 of the present application is recessed inward at the end position near the free end of the brewing head 2 to form an anti-slipping stop 4011. During powder compacting or extraction, the brewing head 2 will be subjected to an upward thrust F from the coffee powder. This thrust F will push the brewing head 2 and the guide shaft 3 upward, so that the guide shaft 3 will be pushed into the anti-slipping stop 4011. The anti-slipping stop 4011 prevents the guide shaft 3 from being dislodged from the hook-shaped structure of the guide groove 401 due to excessive thrust F.

[0044] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
