[0040] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0041] like Figures 1 to 3 As shown, the pressure residue discharge mechanism 100 of an embodiment includes a brewing body 110, a brewing material support 130 and a filter powder cup 140; the brewing body 110 is equipped with a pressure water pump 120, and the outlet pipe 1210 of the pressure water pump 120 is connected to the liquid outlet 1110 of the brewing body 110; the brewing material support 130 is connected to the brewing body 110, and the brewing material support 130 is provided with a docking port 1310, a mounting cavity 1320 and a discharge port 1330 which are connected in sequence; the docking port 1310 is connected to the liquid outlet 1110 of the brewing body 110, and is connected to the outlet pipe 1210 of the pressure water pump 120; the filter powder cup 140 is used to place coffee The coffee powder 20 and the filter cup 140 are detachably arranged in the installation cavity 1320, and a plurality of filter holes 1410 are evenly opened on the bottom of the filter cup 140; when filtering the coffee powder 20, the mouth of the filter cup 140 faces the docking port 1310 and is connected to the outlet pipe 1210 of the pressure water pump 120; the bottom of the filter cup 140 is connected to the discharge port 1330 through the filter holes 1410; when discharging coffee grounds, the mouth of the filter cup 140 faces and is connected to the discharge port 1330; the bottom of the filter cup 140 faces the docking port 1310, and a plurality of filter holes 1410 are connected to the outlet pipe 1210 of the pressure water pump 120.

[0042] Combination Figure 2As shown, it can be understood that by connecting the docking port 1310 of the extraction material support 130 to the liquid outlet 1110 of the brewing body 110, the outlet pipe 1210 of the pressure water pump 120 is connected to the docking port 1310 of the extraction material support 130. Because the filter powder cup 140 is detachably arranged in the installation cavity 1320, when it is necessary to filter the coffee powder 20 to brew coffee, by making the cup mouth of the filter powder cup 140 face the docking port 1310, the cup mouth of the filter powder cup 140 is connected to the outlet pipe 1210 of the pressure water pump 120, and the pressure water pump Under the action of the pressure water pump 120, the water in 120 is quickly discharged from the outlet pipe 1210 of the pressure water pump 120 to the docking port 1310 of the extraction material bracket 130, and the discharged water then enters through the cup mouth of the filter powder cup 140 and brews the coffee powder 20 placed in the filter powder cup 140, and the bottom of the filter powder cup 140 is connected to the discharge port 1330 through the filter holes 1410, so that the water can be discharged from the discharge port 1330 of the extraction material bracket 130 through the filter holes 1410 of the filter powder cup 140 after extracting the coffee powder 20, which is convenient and quick to use.

[0043] Combination Figure 3 As shown, it can be understood that after the coffee powder 20 in the filter cup 140 is brewed, the coffee powder 20 will gather and be adsorbed on the bottom of the filter cup 140 to form a cake-like coffee grounds 30, and the cake-like coffee grounds 30 will block each filter hole 1410. At the same time, the water in the pressure water pump 120 is drained. Because the filter cup 140 is detachably arranged in the installation cavity 1320, when it is necessary to drain the cake-like coffee grounds 30, by making the bottom of the filter cup 140 face the docking port 1310, a plurality of filter holes 1410 are connected to the pressure water pump 120. The outlet pipe 1210 of the pump 120, the air in the pressure water pump 120 is rapidly discharged from the outlet pipe 1210 of the pressure water pump 120 to the docking port 1310 of the extraction material support 130 under the action of the pressure water pump 120, and the discharged air acts on the cake-like coffee grounds 30 at the bottom of the filter powder cup through the filter holes 1410, and the cup mouth of the filter powder cup 140 faces and is connected to the discharge port 1330, and the cake-like coffee grounds 30 are completely discharged from the discharge port 1330 of the extraction material support 130 under the push of the air, and the discharge is convenient and fast.

[0044] It can be understood that compared with the portable electric pressure coffee machine in the prior art, the pressure residue discharge mechanism 100 is because the filter powder cup 140 is detachably arranged in the installation cavity 1320. When the filter powder 20 needs to be filtered to brew coffee, the user can quickly turn the cup mouth of the filter powder cup 140 toward the docking port 1310, so that the water in the pressure water pump 120 can efficiently extract the coffee powder 20 through the cup mouth of the filter powder cup 140. When the cake-shaped coffee residue 30 needs to be discharged, the user can The bottom of the filter cup 140 can be quickly directed toward the docking port 1310, so that the air in the pressure water pump 120 can act on the cake-like coffee grounds 30 through the filter holes 1410 at the bottom of the filter cup to achieve efficient discharge of the grounds, which not only avoids the tedious process of manual discharge of the grounds, but also the air passing through the filter holes 1410 can make the cake-like coffee grounds 30 evenly stressed as a whole and completely escape from the bottom of the filter cup 140, so that the bottom of the filter cup 140 can be quickly cleaned.

[0045] Combination Figure 2 and Figure 3 As shown, in one embodiment, the cup body of the filter powder cup 140 is embedded in the installation cavity 1320; when filtering the coffee powder 20, the cup mouth of the filter powder cup 140 is snap-connected or screwed to the docking port 1310; when discharging the coffee grounds, the cup mouth of the filter powder cup 140 is snap-connected or screwed to the discharge port 1330. It can be understood that by embedding the cup body of the filter press powder cup 140 in the installation cavity 1320, because the cup mouth of the filter press powder cup 140 is snap-connected or screwed to the docking port 1310, the water in the pressure water pump 120 can enter the filter press powder cup 140 from the docking port 1310 to brew coffee. At the same time, when the coffee is filled, the user can easily remove the cup mouth of the filter press powder cup 140 from the docking port 1310 and invert the filter press powder cup 140 in the installation cavity 1320 so that the cup mouth of the filter press powder cup 140 is snap-connected or screwed to the discharge port 1330. The air in the pressure water pump 120 acts on the cake-like coffee grounds 30 at the bottom of the filter cup through the filter holes 1410, so that the cake-like coffee grounds 30 can be discharged from the discharge port 1330 more quickly. Similarly, when the residue discharge is completed, the user can easily remove the cup mouth of the filter press powder cup 140 from the discharge port 1330, so that the filter cup can be quickly reset.

[0046] Combination Figure 2As shown, in this embodiment, the cup mouth of the filter powder cup 140 is bent and extended outward to form a hanging edge 1420; a sealing sheet 150 is provided in the liquid outlet of the brewing body 110, and the sealing sheet 150 is used to abut against the hanging edge 1420 when filtering coffee powder; the outer wall of the docking port 1310 is screwed to the inner wall of the liquid outlet 1110 of the brewing body 110. It can be understood that when the coffee powder 20 is filtered, the hanging edge 1420 is buckled on the end face of the docking port 1310 and abuts against the sealing sheet 150; the outlet pipe 1210 of the pressure water pump 120 is connected to the cup mouth of the filter powder cup 140 through the through port 1510 of the sealing sheet 150, and the extraction material bracket 130 can be twisted to make the docking port 1310 push the hanging edge 1420 against the sealing sheet 150, thereby sealing the cup mouth of the filter powder cup 140, and the outlet pipe 1210 of the pressure water pump 120 is connected to the cup mouth of the filter powder cup 140 through the through port 1510 of the sealing sheet 150, the water in the outlet pipe 1210 of the pressure water pump 120 can smoothly enter the filter powder cup 140 to brew coffee, and at the same time can effectively prevent water from leaking from the cup mouth of the filter powder cup 140.

[0047] Combination Figure 3 As shown, further, a sealing ring 1340 is convexly provided on the cavity wall of the installation cavity 1320, and the sealing ring 1340 is arranged close to the discharge port 1330; when the coffee grounds are discharged, the hanging edge 1420 is buckled on the end surface of the discharge port 1330, and the sealing ring 1340 is held against the outer cup wall of the filter powder cup 140. It can be understood that by buckling the hanging edge 1420 on the end surface of the discharge port 1330, the filter powder cup 140 can be inverted in the installation cavity 1320, and at the same time, the outer cup wall of the filter powder cup 140 is held by the sealing ring 1340, so that the filter powder cup 140 can not only be firmly installed in the installation cavity 1320, but also the sealing ring 1340 can fill the gap between the outer cup wall of the filter powder cup 140 and the cavity wall of the installation cavity 1320. The bottom of the cup 140 faces the docking port 1310. When the docking port 1310 is pressed against the sealing sheet 150 by twisting the extraction material bracket 130, the air tightness between the bottom of the filter cup 140 and the sealing sheet 150 can be improved. The air in the outlet pipe 1210 of the pressure water pump 120 can act on the cake-like coffee grounds 30 through the filter holes 1410 at the bottom of the filter cup 140, so that the cleaning efficiency of the cake-like coffee grounds 30 is faster and the effect is better.

[0048] Combination Figure 3As described, in one embodiment, the discharge port 1330 extends out of the liquid outlet 1110 of the brewing body 110, and the outer sleeve 1350 is connected to the extraction material support 130, and the anti-slip sleeve 1350 is arranged near the discharge port 1330. It can be understood that because the discharge port 1330 extends out of the liquid outlet 1110 of the brewing body 110, by arranging the anti-slip sleeve 1350 near the discharge port 1330, the user can more conveniently twist the extraction material support 130 by holding the anti-slip sleeve 1350 to disassemble the docking port 1310 from the liquid outlet 1110 of the brewing body 110, and at this time, the cup mouth of the filter press powder cup 140 can be clamped to the docking port 1310 or the discharge port 1330, which makes it more convenient for the user to quickly adjust the cup mouth direction of the filter press powder cup 140.

[0049] Combination Figure 2 As shown, further, the pressure residue discharge mechanism 100 further includes a liquid receiving cup 1360, the cup mouth of the liquid receiving cup 1360 is opposite to the liquid outlet 1110 of the brewing body 110; the discharge port 1330 of the extraction material support 130 extends into the cup cavity of the liquid receiving cup 1360, and the discharge port 1330 is connected to the cup cavity of the liquid receiving cup 1360; the anti-slip screw sleeve 1350 is clamped on the cup cavity wall of the liquid receiving cup 1360. It can be understood that the cup cavity of the liquid receiving cup 1360 is clamped on the extraction material support 130 through the anti-slip screw sleeve 1350, so that the liquid receiving cup 1360 can be firmly docked with the liquid outlet 1110, and by making the discharge port 1330 connected to the cup cavity of the liquid receiving cup 1360, the coffee liquid discharged from the discharge port 1330 can be contained in the liquid receiving cup 1360. When the coffee grounds 30 need to be discharged, the liquid receiving cup 1360 can be slid off the anti-slip screw sleeve 1350 to remove the liquid receiving cup 1360. The coffee grounds 30 can be quickly discharged through the discharge port, which is more convenient to use.

[0050] Combination Figure 2 As shown, in one embodiment, a connecting bracket 160, a sealing sheet 150 and a first diverter plate 170 are sequentially arranged in the liquid outlet 1110 of the brewing body 110; the disc edge of the first diverter plate 170 and the peripheral edge of the sealing sheet 150 are pressed and sealed to form a first dispersion chamber 17a; the connecting bracket 160 is arranged close to the pressure water pump 120, and a guide pipe 1610 is arranged on the connecting bracket 160, and the outlet pipe 1210 of the pressure water pump 120 is connected to the guide pipe 1610, and the guide pipe 1610 passes through the port 1510 of the sealing sheet 150 and is connected to the first dispersion chamber 17a; the first diverter plate 170 is arranged opposite to the docking port 1310, and a plurality of first diverter holes 1710 are opened; each first diverter hole 1710 is respectively connected to the first dispersion chamber 17a and the docking port 1310.

[0051] It can be understood that the first dispersion chamber 17a is formed between the first diverter disc 170 and the sealing sheet 150 by pressing and sealing the disc edge of the first diverter disc 170 and the sealing sheet 150. Since the outlet pipe 1210 of the pressure water pump 120 is connected to the first dispersion chamber 17a through the guide pipe 1610, the water or air flowing out of the outlet pipe 1210 of the pressure water pump 120 will first enter the first dispersion chamber 17a, and the disc edge of the first diverter disc 170 and the sealing sheet 150 are pressed and sealed. The first diverter disc 170 and the docking port 1310 are arranged opposite to each other, so that the water or air entering the first dispersion chamber 17a can only be dispersed and discharged to the docking port 1310 through the plurality of first diverter holes 1710 on the first diverter disc 170.

[0052] It can be understood that when it is necessary to filter the coffee powder 20 to brew coffee, the mouth of the filter powder cup 140 is facing the docking port 1310, and the water entering the first dispersion chamber 17a is evenly dispersed through a plurality of first diversion holes 1710 and enters from the mouth of the filter powder cup 140 and falls on the coffee powder 20. After dispersion, the impact force of the water is smaller and the flow rate is slower, which not only avoids the situation where the water locally impacts the coffee powder 20 and causes uneven coffee filtering, but also enables the water to contact the coffee powder 20 more evenly and fully to enhance the effect of extracting the coffee powder 20.

[0053] It can be understood that when the cake-like coffee grounds 30 need to be discharged, the cup mouth of the filter cup 140 faces the discharge port 1330, and the air entering the first dispersion chamber 17a is evenly dispersed through a plurality of first diversion holes 1710 and acts on the cake-like coffee grounds 30 from the filter holes 1410 at the bottom of the filter cup 140. After being dispersed twice through the first diversion holes 1710 and the filter holes 1410, the air can be more evenly dispersed, so that the force on each part of the cake-like coffee grounds 30 is more even, and then it can be discharged more completely and quickly from the discharge port 1330, which can avoid the situation where the cake-like coffee grounds 30 are broken during the discharge process, resulting in difficulty in cleaning.

[0054] Combination Figure 2 and Figure 4As shown, specifically, the lumen of the guide tube 1610 is divided into a guide port 1611, a slow flow chamber 1612 and a diversion port 1613 which are connected in sequence; the guide port 1611 sealing sleeve is arranged outside the outlet pipe 1210 of the pressure water pump 120, and is connected to the outlet pipe 1210 of the pressure water pump 120; the diversion port 1613 passes through the port 1510 of the sealing plate 150 and is pressed against the first diversion plate 170; the end face of the diversion port 1613 is radially provided with a plurality of circumferential flow channels 161a, and the diversion port 1613 is respectively connected to the first dispersion chamber 17a through each circumferential flow channel 161a, and the slow flow chamber 1612 is used to slow the water or air in the guide tube 1610. It can be understood that because the sealing sleeve of the drainage port 1611 is arranged outside the outlet pipe 1210 of the pressure water pump 120, the sealing performance between the drainage port 1611 and the outlet pipe 1210 of the pressure water pump 120 is better, so that the water or air flowing out of the outlet pipe 1210 of the pressure water pump 120 can flow more smoothly through the drainage port 1611 and the slow flow cavity 1612 to the diverter port 1613, further lengthening the flow path of the water or air and reducing the impact force of the water or air. In addition, because the diverter port 1613 is pressed against the first diverter disk 170, the circumferential flow channel 161a is radially opened on the end face of the diverter port 1613, and the water or air will first impact the disk surface of the first diverter disk 170. The kinetic energy of water or air will be further lost during the impact process and will be dispersed into multiple streams of fluid. The multiple streams of fluid flow into the first dispersion chamber 17a from each circumferential flow channel 161a respectively. After the water or air is dispersed into multiple streams of fluid, the kinetic energy will be further reduced.

[0055] Combination Figures 3 to 5 As shown, further, the first flow diverter plate 170 is provided with a plurality of flow spoiler piles 1720 protruding into the first dispersion chamber 17a, and the plurality of flow spoiler piles 1720 are collectively surrounded outside the flow diverter port 1613, and the flow spoiler piles 1720 are arranged one by one opposite to the outlet of the circumferential flow channel 161a, and a flow gap 1721 is formed between two adjacent flow spoiler piles 1720. It can be understood that because the flow spoiler piles 1720 are arranged one by one opposite to the outlet of the circumferential flow channel 161a, the fluid flowing out of the circumferential flow channel 161a will hit the flow spoiler piles 1720 again and be dispersed, and the kinetic energy of water or air will be lost again during the impact process, and the dispersed fluid will enter the first dispersion chamber 17a from the flow gap 1721, and finally the fluid in the first dispersion chamber 17a can be evenly distributed on the entire disk surface of the first flow diverter plate 170.

[0056] Combination Figure 6 and Figure 7As shown, the transverse cross section of the flow-disturbing pile 1720 is a fan ring, and the inner arc edge of the fan ring is arranged opposite to the outlet of the circumferential flow channel 161a; a flow gap 1721 is formed between the sides of two adjacent flow-disturbing piles 1720. It can be understood that by arranging the inner arc edge of the fan ring opposite to the outlet of the circumferential flow channel 161a, when the fluid flows out of the circumferential flow channel 161a, the fluid will impact the surface formed by the inner arc edge of the fan ring and be split into two split fluids, and the split fluids can flow more smoothly through the flow gap 1721 to the first dispersion chamber 17a under the guidance of the corresponding side edge of the fan ring.

[0057] Combination Figure 4 As shown, in one embodiment, the drainage port 1611 and the diversion port 1613 are staggered in the vertical direction, and the cavity wall of the slow flow cavity 1612 is tilted downward from one end close to the drainage port 1611 to one end close to the diversion port 1613. It can be understood that because the cavity wall of the slow flow cavity 1612 is tilted downward from one end close to the drainage port 1611 to one end close to the diversion port 1613, the air or water flowing in from the drainage port 1611 will impact the cavity wall of the slow flow cavity 1612, and the air or water will rub against the cavity wall of the slow flow cavity 1612 to reduce the kinetic energy, further slowing down the flow rate of the air or water, so that the air or water can be dispersed more evenly later.

[0058] Combination Figure 2 and Figure 3As shown, in one embodiment, a second diverter plate 180 is further provided on one side of the first diverter plate 170 close to the docking port 1310; the edge of the second diverter plate 180 is tightly sealed with the periphery of the first diverter plate 170 to form a second dispersion chamber 17b; a plurality of second diverter holes 1810 are provided on the second diverter plate 180; the first diverter hole 1710, the second dispersion chamber 17b, the second diverter hole 1810 and the docking port 1310 are sequentially connected. It can be understood that by pressing and sealing the edge of the second diverter plate 180 and the periphery of the first diverter plate 170, a second dispersion chamber 17b is formed between the second diverter plate 180 and the first diverter plate 170. Since the first diverter hole 1710, the second dispersion chamber 17b, the second diverter hole 1810 of the first diverter plate 170 and the docking port 1310 are sequentially connected, air or water can enter the second dispersion chamber 17b after being evenly dispersed through the first diverter hole 1710, and the air or water is dispersed for the second time in the second dispersion chamber 17b through the second diverter hole 1810. When it is necessary to discharge the cake-shaped coffee grounds 30, the impact force and flow rate of the water are further reduced after the second dispersion, further avoiding the situation that the water impacts the coffee powder 20 and causes uneven coffee pressing and filtering, and can make the water more evenly dispersed and more fully contact the coffee powder 20, and finally further improve the extraction effect of the water on the coffee powder 20. At the same time, when the cake-like coffee grounds 30 need to be discharged, the air can be dispersed more evenly after passing through the first diversion hole 1710, the second diversion hole 1810 and the filter hole 1410. The impact force and flow rate of the fully dispersed air will be further reduced, so that the air thrust on the cake-like coffee grounds 30 will be more uniform, and finally the cake-like coffee grounds 30 can be discharged more smoothly and completely from the discharge port 1330.

[0059] Combination Figure 3 and Figure 5 As shown, further, the first diverter plate 170 is provided with a plurality of first spoiler struts 1730 protruding into the first dispersion chamber 17a; each first spoiler strut 1730 is in contact with the sealing sheet 150, and a first spoiler gap 1731 is formed between each first spoiler strut 1730 and any adjacent first spoiler strut 1730; the second diverter plate 180 is provided with a plurality of second spoiler struts 1740 protruding into the second dispersion chamber 17b; each second spoiler strut 1740 is in contact with the second diverter plate 180, A second spoiler gap 1741 is formed between each second spoiler support column 1740 and any adjacent second spoiler support column 1740; a plurality of first spoiler support columns 1730 and a plurality of second spoiler support columns 1740 are staggered with the positions of a plurality of first diversion holes 1710, and each first spoiler gap 1731 is connected to the corresponding second spoiler gap 1741 through the corresponding first diversion hole 1710, and each second spoiler gap 1741 is connected to the docking interface 1310 through the corresponding second diversion hole 1810.

[0060] It can be understood that by making each first spoiler support column 1730 abut against the sealing sheet 150, the sealing sheet 150 and the first dispersion disk are spread apart to form a first dispersion chamber 17a with a stable volume; by making each second spoiler support column 1740 abut against the second diverter disk 180, the first dispersion disk and the second diverter disk 180 are spread apart to form a second dispersion chamber 17b with a stable volume. At the same time, because a second spoiler gap 1741 is formed between each second spoiler support column 1740 and any adjacent second spoiler support column 1740, and a second spoiler gap 1741 is formed between each second spoiler support column 1740 and any adjacent second spoiler support column 1740, a plurality of first spoiler support columns 1730 and a plurality of second spoiler support columns 1740 are staggered from the positions of a plurality of first diverter holes 1710, so that the air or water in the first dispersion chamber 17a will repeatedly collide with the first spoiler support column 1730 during the flow process. The support pillars 1730 are repeatedly dispersed, and the dispersed air or water penetrates into the first spoiler gap 1731 and enters the second dispersion chamber 17b through the corresponding first diversion hole 1710. The air or water will repeatedly hit the second spoiler support pillars 1740 during the flow process and be further dispersed. The dispersed air or water penetrates into the second spoiler gap 1741 and enters the docking port 1310 through the corresponding second diversion hole 1810, and finally enters the filter powder cup 140 from the docking port 1310 and is dispersed more evenly.

[0061] Combination Figure 1 and Figure 3 As shown, in one embodiment, the pressure residue discharge mechanism 100 further includes a soft carrying strap 190; a mounting surface 1120 is provided on one side of the brewing body 110, and a charging port 1121 is provided on the mounting surface 1120; the soft carrying strap 190 is buckled on the mounting surface 1120, and a waterproof plug 1930 that can be matched with the charging port 1121 is provided on the soft carrying strap 190. It can be understood that because the soft carrying strap 190 is buckled on the mounting surface 1120, when the user presses the coffee powder 20 or discharges the coffee residue, the part of the soft carrying strap 190 can be untied from the mounting surface 1120, and the untied soft carrying strap 190 can be hung on the wall, thereby suspending the entire pressure residue discharge mechanism 100. After being suspended, the pressure residue discharge mechanism 100 can press the coffee or discharge the coffee residue more stably, avoiding fatigue and instability of the human hand holding. At the same time, the soft carrying strap 190 is provided with a waterproof plug 1930 that can be adapted to the charging port 1121. After the pressure slag discharge mechanism 100 is used, the waterproof plug 1930 is blocked by the soft carrying strap 190 being buckled on the mounting surface 1120, which can effectively prevent water from entering the charging port 1121 and causing a short circuit in the pressure slag discharge mechanism 100.

[0062] In this embodiment, a fixing buckle 1122 is respectively disposed at both ends and the middle of the mounting surface 1120, and a button hole 1910 is respectively opened at both ends and the middle of the soft carrying strap 190; Figure 1 As shown, when the soft carrying strap 190 is laid on the mounting surface 1120, the button holes 1910 and the fixing buckles 1122 are buckled one by one; Figure 3 As shown, when the soft carrying strap 190 is used for hanging, one of the buttonholes 1910 located at both ends of the soft carrying strap 190 is buckled to a fixing buckle 1122 located in the middle of the mounting surface 1120, and the other buttonholes 1910 are buckled to a fixing buckle 1122 located at either end of the mounting surface 1120. The soft carrying strap 190 is bent from both ends to the middle to form a hanging ear 1920, and the hanging ear 1920 protrudes from the mounting surface 1120. It can be understood that when the soft carrying strap 190 is laid on the installation surface 1120, the button holes 1910 are buckled one-to-one with the fixing buckles 1122, which not only allows the soft carrying strap 190 to be more securely stored on the installation surface 1120, but also allows the waterproof plug 1930 to more securely block the charging port 1121; when the soft carrying strap 190 is used for hanging, the soft carrying strap 190 is bent from both ends to the middle to form the hanging ears 1920, and the user can hang the pressure slag discharge mechanism 100 on the wall through the hanging ears 1920.

[0063] like Figure 6 As shown, the present disclosure further provides a portable pressure coffee machine 10, comprising a pressure residue discharge mechanism 100 of any of the above-mentioned embodiments. It can be understood that by applying the pressure residue discharge mechanism 100 of the present disclosure to the portable pressure coffee machine 10, the air in the pressure water pump 120 can act on the cake-shaped coffee residue 30 through the filter holes 1410 at the bottom of the filter cup to achieve efficient residue discharge, which not only avoids the tedious process of manual residue discharge, but also the air passing through the filter holes 1410 can make the cake-shaped coffee residue 30 evenly stressed as a whole and completely escape from the bottom of the filter cup 140, so that the bottom of the filter cup 140 can be quickly cleaned.

[0064] Compared with the prior art, the present invention has at least the following advantages:

[0065] 1) By connecting the docking port 1310 of the extraction material support 130 to the liquid outlet 1110 of the brewing body 110, the outlet pipe 1210 of the pressure water pump 120 is connected to the docking port 1310 of the extraction material support 130. Since the filter powder cup 140 is detachably arranged in the installation cavity 1320, when the filter powder 20 needs to be filtered to brew coffee, the cup mouth of the filter powder cup 140 is directed toward the docking port 1310, so that the cup mouth of the filter powder cup 140 is connected to the outlet pipe 1210 of the pressure water pump 120, and the pressure water pump 120 The water in the coffee making machine is rapidly discharged from the outlet pipe 1210 of the pressure water pump 120 to the docking port 1310 of the extraction material support 130 under the action of the pressure water pump 120, and the discharged water then enters through the cup mouth of the filter powder cup 140 and brews the coffee powder 20 placed in the filter powder cup 140, while the bottom of the filter powder cup 140 is connected to the discharge port 1330 through the filter holes 1410, so that the water can be discharged from the discharge port 1330 of the extraction material support 130 through the filter holes 1410 of the filter powder cup 140 after extracting the coffee powder 20, which is convenient and quick to use.

[0066] 2) After brewing, the coffee powder 20 in the filter cup 140 will gather and be adsorbed on the bottom of the filter cup 140 to form a cake-shaped coffee grounds 30, which will block the filter holes 1410. At the same time, the water in the pressure water pump 120 is drained. Because the filter cup 140 is detachably arranged in the installation cavity 1320, when it is necessary to drain the cake-shaped coffee grounds 30, the bottom of the filter cup 140 is directed toward the docking port 1310, so that the filter holes 1410 are connected to the pressure water pump 120. 0, the air in the pressure water pump 120 is rapidly discharged from the outlet pipe 1210 of the pressure water pump 120 to the docking port 1310 of the extraction material support 130 under the action of the pressure water pump 120, and the discharged air acts on the cake-like coffee grounds 30 at the bottom of the filter powder cup through the filter holes 1410, and the cup mouth of the filter powder cup 140 faces and is connected to the discharge port 1330, and the cake-like coffee grounds 30 are completely discharged from the discharge port 1330 of the extraction material support 130 under the push of the air, and the discharge is convenient and fast.

[0067] 3) Compared with the portable electric pressure coffee machine in the prior art, the pressure residue discharge mechanism 100 is detachably arranged in the installation cavity 1320 because the filter powder cup 140 is detachably arranged in the installation cavity 1320. When the filter powder 20 needs to be filtered to brew coffee, the user can quickly turn the cup opening of the filter powder cup 140 toward the docking port 1310, so that the water in the pressure water pump 120 can efficiently extract the coffee powder 20 through the cup opening of the filter powder cup 140. When the cake-shaped coffee residue 30 needs to be discharged, the user can The bottom of the filter cup 140 is quickly directed toward the docking port 1310, so that the air in the pressure water pump 120 can act on the cake-like coffee grounds 30 through the filter holes 1410 at the bottom of the filter cup to achieve efficient discharge of the grounds, which not only avoids the tedious process of manual discharge of the grounds, but also the air passing through the filter holes 1410 can make the cake-like coffee grounds 30 evenly stressed as a whole and completely escape from the bottom of the filter cup 140, so that the bottom of the filter cup 140 can be quickly cleaned.

[0068] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
