Therefore, they cannot be understood as limiting the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Example 1

[0040] See Figure 1-6 The present utility model discloses a novel hand-pressed coffee machine, comprising a machine body 1, a pressure rod assembly 2 disposed on the upper portion of the machine body 1, and a coffee extraction assembly disposed on the lower portion of the machine body 1. The upper portion of the machine body 1 defines a water storage chamber 11 for storing hot water, and the lower portion defines an extraction chamber 12 for extracting coffee. A water inlet channel 13 is defined in the lower portion of the machine body 1, connecting the water storage chamber 11 and the extraction chamber 12. Furthermore, the machine body 1 is provided with a first filter 14 disposed between the water inlet channel 13 and the extraction chamber 12. The first filter 14 has a plurality of first filter holes. Thus, under the action of the pressure rod assembly 2, hot water in the water storage chamber 11 can enter the water inlet channel 13, and then pass through the first filter 14 into the extraction chamber 12 to extract the coffee.

[0041] For details, see Figure 2-3 The pressure rod assembly 2 includes a shell 21 installed on the top of the fuselage 1 and a pressure rod 22 movably arranged in the shell 21. The lower end of the pressure rod 22 passes through the water storage chamber 11 and extends into the water inlet channel 13. The lower end of the pressure rod 22 is provided with a piston head 23. The outer wall of the piston head 23 is provided with an annular limit groove and a water inlet groove connected to the limit groove. Among them, it also includes a sealing ring 24 that is sleeved on the piston head 23 and located in the limiting groove. The outer side of the sealing ring 24 abuts against the inner wall of the water inlet channel 13 to form a waterproof seal; thus, when the pressure rod 22 is driven to move up and down, the piston head 23 can be synchronously driven to move up and down and abut the sealing ring 24 through the limiting groove to drive the sealing ring 24 to move up and down; when the piston head 23 moves up, the sealing ring 24 abuts against the bottom wall of the limiting groove. At this time, the water located on the upper part of the piston head 23 can flow into the lower part of the piston head 23 through the water inlet groove under the action of pressure; when the piston head 23 moves down, the sealing ring 24 abuts against the top wall of the limiting groove, and a seal can be formed with the water on the upper part of the piston head 23. The downward movement of the piston head 23 presses the water located at the lower part of the piston head 23 into the extraction chamber 12.

[0042] Therefore, the new hand-pressed coffee machine of the present invention can realize the water inlet and outlet in the water inlet channel 13 through the up and down movement of the piston head 23 and the sealing ring 24. Compared with the traditional method of setting a double valve core on the hand pump, the present application not only has a simple structure and a small number of parts, but also has low requirements on the assembly accuracy of parts and components, low requirements on the processing accuracy of parts, and high assembly efficiency.

[0043] Preferably, the upper end of the pressure rod 22 passes through the shell 21 and is provided with a pressure rod head 25 at its upper end, so that the user can hold it conveniently and drive the pressure rod 22 to move up and down relative to the shell 21, thereby continuously realizing the water inlet and outlet in the water inlet channel 13, thereby realizing the extraction of coffee.

[0044] It can be understood that a spring is also provided in the housing 21 to abut against the pressure rod 22. When the user presses the pressure rod 22 with his hand and drives it to move downward, the spring is compressed and stores potential energy. When the user releases the pressure rod 22, the pressure rod 22 can be reset and moved upward under the action of the spring's elastic force, thereby saving time and effort.

[0045] In this embodiment, the outer wall of the upper portion of the fuselage 1 is provided with an external thread, and the inner wall of the outer shell 21 is provided with an internal thread that matches the external thread; thus, a detachable connection between the pressure rod assembly 2 and the fuselage 1 can be achieved through the threaded connection between the two.

[0046] See Figure 4 The piston head 23 includes a cylindrical main body 231 and a first convex ring portion 232 and a second convex ring portion 233 arranged on the outer side wall of the main body 231 and spaced apart from each other. The main body 231, the first convex ring portion 232 and the second convex ring portion 233 form an annular limit groove; wherein, the outer side wall of the main body 231 is provided with a plurality of first grooves 2311, and the second convex ring portion 233 is provided with a plurality of second grooves 2331 which are respectively connected to the plurality of first grooves 2311 and pass through the upper and lower parts. The first grooves 2311 and the second grooves 2331 together form a water inlet groove; the outer sides of the first convex ring portion 232 and the second convex ring portion 233 leave a certain gap with the inner side wall of the water inlet channel 13.

[0047] Therefore, when the piston head 23 is driven to move upward, the sealing ring 24 abuts against the top of the second convex ring portion 233 (as shown in FIG. Figure 5 As shown in FIG2 , at this time, the water at the upper part of the piston head 23 can enter the limit groove through the gap between the first convex ring portion 232 and the water inlet channel 13, and then flow out through the first groove 2311 and the second groove 2331 in sequence and enter the lower part of the piston head 23; and when the piston head 23 moves downward, the sealing ring 24 abuts against the bottom wall of the first convex ring portion 232 (as shown in FIG2 ). Figure 6 As shown), the sealing ring 24 seals the gap between the first convex ring portion 232 and the water inlet channel 13. At this time, the water located above the piston head 23 cannot enter the piston head 23. At this time, the piston head 23 moves downward to press the water located below the piston head 23 into the extraction chamber 12.

[0048] Preferably, the piston head 23 also includes a sleeve-shaped connecting portion 234 arranged on the first convex ring portion 232, the inner side wall of the connecting portion 234 is provided with an internal thread, and the outer side wall of the lower end portion of the pressure rod 22 is provided with an external thread matching it, and the two are connected by threads to achieve detachable fixation.

[0049] See also Figure 3 as well as Figure 5-6The water inlet channel 13 includes a first water inlet channel 131 and a second water inlet channel 132 arranged vertically and interconnected. The aperture of the first water inlet channel 131 is larger than that of the second water inlet channel 132. The sealing ring 24 and the piston head 23 both move up and down in the first water inlet channel 131; the first filter screen 14 is located between the second water inlet channel 132 and the extraction chamber 12.

[0050] The second water inlet channel 132 is also provided with a first one-way valve assembly 15. When the piston head 23 is driven downward, water is driven to push against the first one-way valve assembly 15, placing it in a conductive state. When the piston head 23 is driven upward, the first one-way valve assembly 15 is similarly reset and seals the second water inlet channel 132, thereby preventing coffee liquid in the extraction chamber from flowing back into the second water inlet channel 132.

[0051] It should be noted that the first one-way valve assembly 15 can be purchased on the market, and its structure and working principle can be learned by referring to the existing technology. It is not the focus of protection of this application, so it will not be described here.

[0052] See also 3 and Figure 5-6 The coffee extraction component includes a support 3 and a powder bowl 4 that can be detachably placed on the support 3; specifically, the upper part of the support 3 is provided with a concave cavity 31 with an open top, and the powder bowl 4 can be placed in or taken out of the concave cavity 31, and the lower part of the support 3 is provided with a liquid outlet channel 32 with an open bottom and connected to the bottom of the concave cavity 31.

[0053] Therefore, when the support 3 is installed at the lower part of the machine body 1, the powder bowl 4 is located in the extraction chamber 12. When the piston head 23 moves downward, hot water can be pressed into the extraction chamber 12 to extract and brew the coffee powder in the powder bowl 4, and then flow out through the liquid outlet channel 32.

[0054] In this embodiment, the lower inner wall of the body 1 is provided with an internal thread, and the outer wall of the support 3 is provided with an external thread matching the internal thread; thus, a detachable connection between the coffee extraction component and the body 1 can be achieved through the threaded connection between the two.

[0055] Furthermore, the powder bowl 4 includes a powder bowl body 41 and a second filter screen 42 arranged in the powder bowl body 41, and the powder bowl body 41 and the second filter screen 42 enclose a powder chamber for placing coffee powder; wherein, the second filter screen 42 is provided with a plurality of second filter holes 421, and the bottom of the powder bowl body 41 is provided with a liquid outlet hole 411 connecting the plurality of second filter holes 421, and the cross-sectional area of ​​the liquid outlet hole 411 is smaller than the sum of the cross-sectional areas of the plurality of second filter holes 421.

[0056] Therefore, by opening the liquid outlet 411 at the bottom of the powder bowl body 41, when the coffee liquid extracted from the second filter hole 421 flows to the liquid outlet 411 with a smaller cross-sectional area, the resistance it encounters will be further increased, thereby achieving secondary extraction of the coffee liquid, so that the extracted coffee liquid is richer in oil, thereby improving the taste and flavor of the coffee.

[0057] In addition, a second one-way valve assembly 33 is provided in the liquid outlet channel 32. When the coffee liquid is sprayed out from the liquid outlet hole 411, the coffee liquid can push against the second one-way valve assembly 33 to put it in a conductive state, thereby preventing the coffee liquid from being directly sprayed out from the liquid outlet channel 32 and causing splashing.

[0058] It should be noted that the second one-way valve assembly 33 can also be purchased on the market, and its structure and working principle can be learned by referring to the existing technology. It is not the focus of protection of this application, so it will not be described here.

[0059] In addition, a coffee cup 5 is detachably mounted on the support 3 to collect the coffee liquid flowing out of the liquid outlet channel 32. When coffee needs to be extracted, the coffee cup 5 can be removed from the support 3. When the coffee is finished, the coffee cup 5 can be mounted on the support 3 for storage, which is simple and convenient.

[0060] Example 2

[0061] See Figure 7 The difference between the hand-press coffee machine in this embodiment and the first embodiment is that the hand-press coffee machine in this embodiment does not have the first one-way valve assembly 15 in the second water inlet channel 132. Since the first filter screen 14 is provided, when the piston head 23 is driven to reset and move upward, the first filter screen 14 can block most of the backflowing coffee liquid. Therefore, only a small amount of coffee liquid in the extraction chamber 12 will flow back into the second water inlet channel 132, thereby not affecting the normal use of the hand-press coffee machine.

[0062] In summary, the utility model provides a new hand-press coffee machine, which is provided with a water inlet channel 13 connecting the water storage chamber 11 and the extraction chamber 12 respectively in the middle of the machine body 1, and a piston head 23 extending into the water inlet channel 13 and a sealing ring 24 mounted on the piston head 23 are provided at one end of the pressure rod 22. In this way, water can be inlet and outlet in the water inlet channel 13 by cooperating with the up and down movement of the piston head 23 and the sealing ring 24. Compared with the traditional method of setting a double valve core on the hand pressure pump, the present application not only has a simple structure and a small number of parts, but also has low requirements on the assembly accuracy of parts, low requirements on the processing accuracy of parts, and high assembly efficiency.

[0063] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
