Description

Pressure residue discharging mechanism and portable pressure coffee machine TECHNICAL FIELD

[0001] The present application relates to a pressure residue discharging mechanism and a portable pressure coffee machine. BACKGROUND

[0002] With the development of social economy, people's demand for the quality of life is also constantly improving, so that drinking coffee has gradually integrated into our daily life. The existing coffee machine is generally large in size and can only be placed at home for use, which is not conducive to people carrying it. In view of this problem, some manufacturers have made further research and development.

[0003] For example, Chinese patent document CN116491806A discloses a portable electric pressure coffee machine. The drainage module includes a water storage cup, a water pump, a conduit, a drainage assembly, a fixed base, and a limiting frame. The fixed base is connected with the limiting frame, and the limiting frame includes a short protrusion for fixing the drainage assembly. The water storage cup is used to receive and store water. The water pump is used to suck water from the drainage module into the extraction module. The drainage assembly is connected with the water pump and the conduit for changing the direction of water flow. The extraction module includes an adapter cup, a first extraction container, and a second extraction container. The first extraction container is used to place coffee powder, and the second extraction container is used to place a coffee capsule. The adapter cup is connected with the first extraction container or the second extraction container. The control module is used to receive the signal of the sensing module and send instructions to the driving module. The driving module includes a driving motor for driving the water pump in the drainage module. The power module includes a battery for powering the driving module. The heating module can heat the water in the water storage cup.

[0004] However, the design of the above-mentioned portable electric pressure coffee machine has the following problems:

[0005] The above-mentioned portable electric pressure coffee machine, although small in size and more convenient for users to carry, the coffee powder in the extraction container is filtered by the high-pressure water of the water pump to realize coffee brewing, which will cause the coffee powder after brewing to be tightly adsorbed on the bottom of the extraction container to form a cake-shaped coffee residue. When it is necessary to brew coffee again, the user needs to manually remove the cake-shaped coffee residue from the extraction container. The process of removing the cake-shaped coffee residue is not only repeated and tedious, but also difficult to clean the bottom of the extraction container. SUMMARY

[0006] Therefore, it is necessary to provide a pressure residue discharging mechanism and a portable pressure coffee machine which are self-cleaning and convenient and fast to use.

[0007] A pressure residue discharging mechanism, comprising:

[0008] a brewing main body, wherein a pressure water pump is built in the brewing main body, and an outlet pipe of the pressure water pump is communicated with a liquid outlet of the brewing main body;

[0009] The pressure residue discharge mechanism further comprises a material extraction support and a filter powder cup.

[0010] The material extraction support is connected to the brewing main body, and the material extraction support is provided with a connecting interface, a mounting cavity and a residue discharge port in sequence.

[0011] The filter powder cup is used for placing coffee powder, and the filter powder cup is detachably arranged in the mounting cavity, and a plurality of filter holes are uniformly arranged on the bottom of the filter powder cup.

[0012] A portable pressure coffee machine comprises the pressure residue discharge mechanism of any one of the above embodiments.

As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0025] As shown in FIGS. 1-3, a pressure residue discharge mechanism 100 of an embodiment includes a brewing body 110, a material support 130, and a filter cup 140; the brewing body 110 is internally provided with a pressure water pump 120, an outlet pipe 1210 of the pressure water pump 120 is connected to a liquid outlet 1110 of the brewing body 110; the material support 130 is connected to the brewing body 110, the material support 130 is provided with a docking port 1310, a mounting cavity 1320, and a discharge port 1330 which are sequentially connected; 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 cup 140 is used for placing coffee powder 20, the filter cup 140 is detachably arranged in the mounting cavity 1320, a bottom of the filter cup 140 is uniformly provided with a plurality of filter holes 1410; when the coffee powder 20 is filtered, a cup opening 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 the coffee residue is discharged, the cup opening 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 the plurality of filter holes 1410 are connected to the outlet pipe 1210 of the pressure water pump 120.

[0026] With reference to FIG. 2, it can be understood that by connecting the docking interface 1310 of the extraction holder 130 to the liquid outlet 1110 of the brewing main body 110, the outlet pipe 1210 of the pressure water pump 120 is connected to the docking interface 1310 of the extraction holder 130. When the filter cup 140 is detachably arranged in the mounting cavity 1320, and when the coffee powder 20 needs to be brewed, the cup opening of the filter cup 140 is directed to the docking interface 1310, so that the cup opening of the filter cup 140 is connected to the outlet pipe 1210 of the pressure water pump 120. The water in the pressure water pump 120 is rapidly discharged from the outlet pipe 1210 of the pressure water pump 120 to the docking interface 1310 of the extraction holder 130 under the action of the pressure water pump 120. The discharged water then enters the filter cup 140 through the cup opening of the filter cup 140 and brews the coffee powder 20 in the filter cup 140. The cup bottom of the filter 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 holder 130 through the filter holes 1410 of the filter cup 140 after extracting the coffee powder 20. The use is convenient and fast.

[0027] With reference to FIG. 3, it can be understood that after the coffee powder 20 in the filter cup 140 is brewed, the coffee powder 20 will gather and adhere to the cup bottom of the filter cup 140 to form a cake-shaped coffee residue 30. The cake-shaped coffee residue 30 blocks the filter holes 1410, and the water in the pressure water pump 120 is discharged. When the cake-shaped coffee residue 30 needs to be discharged, the cup bottom of the filter cup 140 is directed to the docking interface 1310, so that the filter holes 1410 are connected to the outlet pipe 1210 of the pressure water 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 interface 1310 of the extraction holder 130 under the action of the pressure water pump 120. The discharged air acts on the cake-shaped coffee residue 30 on the cup bottom of the filter cup through the filter holes 1410. The cup opening of the filter cup 140 is directed to and connected to the discharge port 1330. The cake-shaped coffee residue 30 is pushed by the air and discharged from the discharge port 1330 of the extraction holder 130. The discharge is convenient and fast.

[0028] It can be understood that, compared with the prior art portable electric pressure coffee machine, the pressure residue discharge mechanism 100 described above can be quickly and efficiently used to brew coffee powder 20 when the user makes the cup opening of the pressure filter cup 140 face the docking interface 1310, so that the water in the pressure water pump 120 can efficiently extract the coffee powder 20 through the cup opening of the pressure filter cup 140; and when the user needs to discharge the cake-shaped coffee residue 30, the user can quickly make the cup bottom of the pressure filter cup 140 face the docking interface 1310, so that the air in the pressure water pump 120 can act on the cake-shaped coffee residue 30 through the filter holes 1410 in the cup bottom of the filter cup to achieve efficient residue discharge. Not only does this avoid 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 uniformly stressed and completely removed from the cup bottom of the pressure filter cup 140, so that the cup bottom of the pressure filter cup 140 can be quickly and completely cleaned.

[0029] In combination with FIGS. 2 and 3, in one embodiment, the cup body of the pressure filter cup 140 is embedded in the mounting cavity 1320; when the pressure filter coffee powder 20, the cup opening of the pressure filter cup 140 is connected or screwed to the docking interface 1310; when discharging the coffee residue, the cup opening of the pressure filter cup 140 is connected or screwed to the discharge port 1330. It can be understood that, by embedding the cup body of the pressure filter cup 140 in the mounting cavity 1320, when the cup opening of the pressure filter cup 140 is connected or screwed to the docking interface 1310, the water in the pressure water pump 120 can enter the pressure filter cup 140 from the docking interface 1310 to brew coffee, and when the coffee brewing is completed, the user can easily detach the cup opening of the pressure filter cup 140 from the docking interface 1310, and invert the pressure filter cup 140 in the mounting cavity 1320, so that the cup opening of the pressure filter cup 140 is connected or screwed to the discharge port 1330, and the air in the pressure water pump 120 acts on the cake-shaped coffee residue 30 in the cup bottom of the filter cup through the filter holes 1410, so that the cake-shaped coffee residue 30 can be quickly discharged from the discharge port 1330. Similarly, when the residue discharge is completed, the user can easily detach the cup opening of the pressure filter cup 140 from the discharge port 1330, so that the filter cup can be quickly reset.

[0030] In combination with FIG. 2, in the embodiment, the cup opening of the filter cup 140 is outwardly bent and extended, and forms a hanging edge 1420; the liquid outlet 1110 of the brewing main body 110 is provided with a sealing sheet 150, which is used to abut against the hanging edge 1420 when the filter coffee powder 20 is pressed; the outer wall of the docking port 1310 is screwed to the inner wall of the liquid outlet 1110 of the brewing main body 110. It can be understood that when the filter coffee powder 20 is pressed, 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 communicated to the cup opening of the filter cup 140 through the through opening 1510 of the sealing sheet 150, and the outlet pipe 1210 of the pressure water pump 120 can be communicated to the cup opening of the filter cup 140 by rotating the extraction support 130 to make the docking port 1310 push the hanging edge 1420 to abut against the sealing sheet 150, thereby sealing the cup opening of the filter cup 140, and the water in the outlet pipe 1210 of the pressure water pump 120 can smoothly enter the filter cup 140 to brew coffee, while effectively preventing the water from leaking out of the cup opening of the filter cup 140.

[0031] In combination with FIG. 3, further, the cavity wall of the mounting cavity 1320 is provided with a sealing abutting ring 1340, which is arranged close to the discharge port 1330; when the coffee residue is discharged, the hanging edge 1420 is buckled on the end face of the discharge port 1330, and the sealing abutting ring 1340 abuts against the outer cup wall of the filter cup 140. It can be understood that by buckling the hanging edge 1420 on the end face of the discharge port 1330, the filter cup 140 can be inverted in the mounting cavity 1320, and by abutting the sealing abutting ring 1340 against the outer cup wall of the filter cup 140, the filter cup 140 can be firmly mounted in the mounting cavity 1320, and the sealing abutting ring 1340 can fill the gap between the outer cup wall of the filter cup 140 and the cavity wall of the mounting cavity 1320, since the cup bottom of the filter cup 140 faces the docking port 1310, when the docking port 1310 abuts against the sealing sheet 150 by rotating the extraction support 130, the air tightness between the cup bottom of the filter cup 140 and the sealing sheet 150 is better, and the air in the outlet pipe 1210 of the pressure water pump 120 can more effectively act on the cake-shaped coffee residue 30 through the filter holes 1410 of the cup bottom of the filter cup 140, so that the cleaning efficiency of the cake-shaped coffee residue 30 is faster and better.

[0032] In combination with the description of Fig. 3, in one embodiment, the discharge port 1330 extends out of the liquid outlet 1110 of the brewing main body 110, the anti-skid sleeve 1350 is sleeved on the extraction support 130, and the anti-skid sleeve 1350 is arranged close to the discharge port 1330. It can be understood that, because the discharge port 1330 extends out of the liquid outlet 1110 of the brewing main body 110, by arranging the anti-skid sleeve 1350 close to the discharge port 1330, the user can more conveniently twist the extraction support 130 to detach the docking interface 1310 from the liquid outlet 1110 of the brewing main body 110 by holding the anti-skid sleeve 1350, at this time, the cup opening of the pressure filtration powder cup 140 can be clamped to the docking interface 1310 or the discharge port 1330, which is more convenient for the user to quickly adjust the direction of the cup opening of the pressure filtration powder cup 140.

[0033] In combination with Fig. 2, further, the pressure discharge mechanism 100 further comprises a liquid receiving cup 1360, the cup opening of the liquid receiving cup 1360 is opposite to the liquid outlet 1110 of the brewing main body 110; the discharge port 1330 of the extraction support 130 extends into the cup cavity of the liquid receiving cup 1360, the discharge port 1330 is communicated with the cup cavity of the liquid receiving cup 1360; and the anti-skid sleeve 1350 is clamped to the wall of the cup cavity of the liquid receiving cup 1360. It can be understood that, by clamping the cup cavity of the liquid receiving cup 1360 to the extraction support 130 through the anti-skid sleeve 1350, the liquid receiving cup 1360 can be firmly docked with the liquid outlet 1110, by making the discharge port 1330 communicated with 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 it is needed to discharge the cake-shaped coffee residue 30, the liquid receiving cup 1360 can be slid off the anti-skid sleeve 1350 to detach the liquid receiving cup 1360, the cake-shaped coffee residue 30 can be quickly discharged outside through the discharge port, and the use is more convenient.

[0034] In combination with Fig. 2, in one embodiment, the liquid outlet 1110 of the brewing main body 110 is sequentially provided with a connecting support 160, a sealing sheet 150 and a first flow dividing disc 170; the disc edge of the first flow dividing disc 170 is tightly sealed with the peripheral edge of the sealing sheet 150, and a first dispersion cavity 17a is formed; the connecting support 160 is arranged close to the pressure water pump 120, the connecting support 160 is provided with a flow guide pipe 1610, the outlet pipe 1210 of the pressure water pump 120 is communicated with the flow guide pipe 1610, the flow guide pipe 1610 is communicated with the first dispersion cavity 17a through the through opening 1510 of the sealing sheet 150; the first flow dividing disc 170 is arranged opposite to the docking interface 1310, and is provided with a plurality of first flow dividing holes 1710; each first flow dividing hole 1710 is respectively communicated with the first dispersion cavity 17a and the docking interface 1310.

[0035] It can be understood that the first dispersion cavity 17a is formed between the first shunt disc 170 and the sealing sheet 150 by the tight sealing of the disc edge of the first shunt disc 170 and the peripheral edge of the sealing sheet 150. Since the outlet pipe 1210 of the pressure water pump 120 is communicated with the first dispersion cavity 17a through the flow 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 cavity 17a. The disc edge of the first shunt disc 170 is tightly sealed with the peripheral edge of the sealing sheet 150, and the first shunt disc 170 is oppositely arranged with the docking port 1310, so that the water or air entering the first dispersion cavity 17a can only be dispersed and discharged to the docking port 1310 through the plurality of first shunt holes 1710 on the first shunt disc 170.

[0036] It can be understood that when the coffee is brewed by the press-filtered coffee powder 20, the cup opening of the press-filtered powder cup 140 is directed to the docking port 1310, and the water entering the first dispersion cavity 17a is uniformly dispersed through the plurality of first shunt holes 1710 and falls on the coffee powder 20 from the cup opening of the press-filtered powder cup 140. The water has a smaller impact force and a slower flow rate after dispersion, which not only avoids the situation that the coffee is not uniformly press-filtered due to the local impact of water on the coffee powder 20, but also enables the water to more uniformly and fully contact the coffee powder 20 to improve the extraction of the coffee powder 20.

[0037] It can be understood that when the cake-shaped coffee residue 30 needs to be discharged, the cup opening of the press-filtered powder cup 140 is directed to the discharge port 1330, and the air entering the first dispersion cavity 17a is uniformly dispersed through the plurality of first shunt holes 1710 and acts on the cake-shaped coffee residue 30 from the filter hole 1410 at the bottom of the press-filtered powder cup 140. The air is more uniformly dispersed after being dispersed twice through the first shunt holes 1710 and the filter hole 1410, so that the cake-shaped coffee residue 30 is more uniformly stressed in each part, and is then more completely and quickly discharged from the discharge port 1330, which can avoid the situation that the cake-shaped coffee residue 30 is broken during the discharge process, causing difficulty in cleaning.

[0038] With reference to FIGS. 2 and 4, in particular, the lumen of the flow guide pipe 1610 is divided into the drainage port 1611, the slow flow cavity 1612 and the shunt port 1613 in sequence; the drainage port 1611 is sealingly sleeved outside the outlet pipe 1210 of the pressure water pump 120 and is communicated with the outlet pipe 1210 of the pressure water pump 120; the shunt port 1613 penetrates through the through port 1510 of the sealing sheet 150 and abuts against the first shunt disc 170; the end surface of the shunt port 1613 is provided with a plurality of circumferential flow channels 161a in the radial direction, and the shunt port 1613 is communicated with the first dispersion cavity 17a through each circumferential flow channel 161a, and the slow flow cavity 1612 is used for slowing down the water or air in the flow guide pipe 1610. It can be understood that, because the drainage port 1611 is sealingly sleeved outside the outlet pipe 1210 of the pressure water pump 120, the sealing 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 more smoothly flow through the drainage port 1611 and the slow flow cavity 1612 to the shunt port 1613, further lengthening the flow path of the water or air and reducing the impact force of the water or air. Because the shunt port 1613 abuts against the first shunt disc 170, and the circumferential flow channels 161a are provided on the end surface of the shunt port 1613 in the radial direction, the water or air will first impact the disc surface of the first shunt disc 170. The kinetic energy of the water or air will be further consumed in the process of impact, and the water or air will be dispersed into a plurality of streams, which flow into the first dispersion cavity 17a from each circumferential flow channel 161a, respectively. After the water or air is dispersed into a plurality of streams, the kinetic energy will be further reduced.

[0039] With reference to FIGS. 3 to 5, further, the first shunt disc 170 is provided with a plurality of turbulence stakes 1720 inside the first dispersion cavity 17a, the plurality of turbulence stakes 1720 collectively surround the shunt port 1613, the turbulence stake 1720 is arranged opposite to the outlet of the circumferential flow channel 161a one by one, and the flow gap 1721 is formed between adjacent two turbulence stakes 1720. It can be understood that, because the turbulence stake 1720 is arranged opposite to the outlet of the circumferential flow channel 161a one by one, the fluid flowing out of the circumferential flow channel 161a will be dispersed again by impacting the turbulence stake 1720, the kinetic energy of the water or air will be consumed again in the process of impact, and the dispersed fluid enters the first dispersion cavity 17a from the flow gap 1721, and finally the fluid in the first dispersion cavity 17a can be uniformly distributed on the disc surface of the entire first shunt disc 170.

[0040] In combination with FIG. 6 and FIG. 7, the transverse section of the spoiler 1720 is a fan ring, and the inner arc of the fan ring is arranged opposite to the outlet of the circumferential flow channel 161a; the side surfaces of two adjacent spoilers 1720 form a flow gap 1721. It can be understood that, by arranging the inner arc 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 of the fan ring and be divided into two sub-flows, and the sub-flows can flow more smoothly into the first dispersion cavity 17a under the guidance of the corresponding side surfaces of the fan ring.

[0041] In combination with FIG. 4, in one embodiment, the flow inlet 1611 and the flow outlet 1613 are arranged vertically staggered, and the cavity wall of the slow flow cavity 1612 is inclined downward from the end close to the flow inlet 1611 to the end close to the flow outlet 1613. It can be understood that, because the cavity wall of the slow flow cavity 1612 is inclined downward from the end close to the flow inlet 1611 to the end close to the flow outlet 1613, the air or water flowing into the flow inlet 1611 will impact the cavity wall of the slow flow cavity 1612, the kinetic energy of the air or water is reduced by the friction with the cavity wall of the slow flow cavity 1612, and the flow rate of the air or water is further reduced, so that the air or water can be more evenly dispersed subsequently.

[0042] In combination with FIG. 2 and FIG. 3, in one embodiment, the first flow distribution disc 170 is further provided with a second flow distribution disc 180 close to one side of the docking interface 1310; the disc edge of the second flow distribution disc 180 is tightly sealed with the peripheral edge of the first flow distribution disc 170, and forms a second dispersion cavity 17b; a plurality of second flow holes 1810 are formed in the second flow distribution disc 180; the first flow hole 1710, the second dispersion cavity 17b, the second flow hole 1810 and the docking interface 1310 are sequentially communicated. It can be understood that by tightly sealing the disc edge of the second flow distribution disc 180 with the peripheral edge of the first flow distribution disc 170, the second dispersion cavity 17b is formed between the second flow distribution disc 180 and the first flow distribution disc 170, and because the first flow hole 1710, the second dispersion cavity 17b, the second flow hole 1810 of the first flow distribution disc 170 and the docking interface 1310 are sequentially communicated, the air or water can enter the second dispersion cavity 17b after being evenly dispersed through the first flow hole 1710, and the air or water is dispersed for the second time in the second dispersion cavity 17b through the second flow hole 1810. When the cake-shaped coffee residue 30 needs to be discharged, the impact force and flow rate of the water are further reduced after being dispersed for the second time, which further avoids the situation that the coffee powder 20 is impacted by the water to cause uneven coffee filtration, and enables the water to be more evenly dispersed and more fully contacted with the coffee powder 20, and finally further improves the extraction effect of the water on the coffee powder 20. At the same time, when the cake-shaped coffee residue 30 needs to be discharged, the air can be more evenly dispersed after being dispersed for three times through the first flow hole 1710, the second flow hole 1810 and the filter hole 1410, and the impact force and flow rate of the fully dispersed air will be further reduced, so that the air thrust on the cake-shaped coffee residue 30 is more uniform, and finally the cake-shaped coffee residue 30 can be more smoothly and completely discharged from the discharge port 1330.

[0043] In combination with FIG. 3 and FIG. 5, further, the first flow distribution disc 170 is further provided with a plurality of first turbulence support columns 1730 towards the first dispersion cavity 17a; each first turbulence support column 1730 abuts against the sealing piece 150, and a first turbulence gap 1731 is formed between each first turbulence support column 1730 and any adjacent first turbulence support column 1730; the second flow distribution disc 180 is further provided with a plurality of second turbulence support columns 1740 towards the second dispersion cavity 17b; each second turbulence support column 1740 abuts against the second flow distribution disc 180, and a second turbulence gap 1741 is formed between each second turbulence support column 1740 and any adjacent second turbulence support column 1740; each first turbulence support column 1730 and each second turbulence support column 1740 is staggered with the position of the corresponding first flow hole 1710, each first turbulence gap 1731 is communicated with the corresponding second turbulence gap 1741 through the corresponding first flow hole 1710, and each second turbulence gap 1741 is communicated with the docking interface 1310 through the corresponding second flow hole 1810.

[0044] It can be understood that by abutting each first turbulence support column 1730 on the sealing sheet 150, the sealing sheet 150 and the first dispersion disc are supported to form a stable volume of the first dispersion cavity 17a; by abutting each second turbulence support column 1740 on the second dispersion disc 180, the first dispersion disc and the second dispersion disc 180 are supported to form a stable volume of the second dispersion cavity 17b. At the same time, because each second turbulence support column 1740 and any adjacent second turbulence support column 1740 form a second turbulence gap 1741 therebetween, each first turbulence support column 1730, each second turbulence support column 1740, and the positions of the corresponding first flow holes 1710 are staggered, so that the air or water in the first dispersion cavity 17a will be repeatedly dispersed by repeatedly hitting the first turbulence support column 1730 during flow, the dispersed air or water penetrates into the first turbulence gap 1731 and enters the second dispersion cavity 17b through the corresponding first flow hole 1710, the air or water will be further dispersed by repeatedly hitting the second turbulence support column 1740 during flow, the dispersed air or water penetrates into the second turbulence gap 1741 and enters the interface 1310 through the corresponding second flow hole 1810, and finally makes the coffee powder 20 from the interface 1310 more evenly dispersed into the filter cup 140.

[0045] In combination with FIG. 1 and FIG. 3, in one embodiment, the pressure residue discharge mechanism 100 further comprises a soft carrying strap 190; one side of the brewing body 110 is provided with a mounting surface 1120, and the mounting surface 1120 is provided with a charging port 1121; the soft carrying strap 190 is buckled on the mounting surface 1120, and the soft carrying strap 190 is provided with a waterproof plug 1930 which can be matched with the charging port 1121. 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, part of the soft carrying strap 190 can be released from the mounting surface 1120, and the released soft carrying strap 190 can be hung on the wall, thereby suspending the entire pressure residue discharge mechanism 100, and the pressure residue discharge mechanism 100 can be more stable when it is suspended to press the coffee or discharge the coffee residue, avoiding the fatigue and instability of the hand holding. At the same time, the soft carrying strap 190 is provided with a waterproof plug 1930 which can be matched with the charging port 1121, when the pressure residue discharge mechanism 100 is used, the waterproof plug 1930 is buckled on the mounting surface 1120 to block the charging port 1121, which can effectively prevent water from entering the charging port 1121 to cause short circuit of the pressure residue discharge mechanism 100.

[0046] In the embodiment, the two ends and the middle part of the mounting surface 1120 are respectively provided with a fixed buckle 1122, and the two ends and the middle part of the soft carrying strap 190 are respectively provided with a buckle eye 1910, and each buckle eye 1910 is buckled to the corresponding fixed buckle 1122. As shown in FIG. 1, when the soft carrying strap 190 is laid on the mounting surface 1120, the buckle eyes 1910 and the fixed buckles 1122 are buckled one by one; as shown in FIG. 3, when the soft carrying strap 190 is used for hanging, in the buckle eyes 1910 located at the two ends of the soft carrying strap 190, one buckle eye 1910 is buckled to the fixed buckle 1122 located at the middle part of the mounting surface 1120, and the other buckle eye 1910 is buckled to the fixed buckle 1122 located at any end of the mounting surface 1120; the soft carrying strap 190 is bent from the two ends to the middle part 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 mounting surface 1120, the buckle eyes 1910 and the fixed buckles 1122 are buckled one by one, which not only enables the soft carrying strap 190 to be more firmly stored on the mounting surface 1120, but also enables the waterproof plug 1930 to be more firmly sealed to the charging port 1121; when the soft carrying strap 190 is used for hanging, the soft carrying strap 190 is bent from the two ends to the middle part to form a hanging ear 1920, and the user can hang the pressure residue discharge mechanism 100 on the wall through the hanging ear 1920.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0050] 2) After the coffee powder 20 in the pressure filter powder cup 140 is brewed, the coffee powder 20 will gather and adsorb on the cup bottom of the pressure filter powder cup 140 to form a cake-shaped coffee residue 30, which blocks each filter hole 1410, and the water in the pressure water pump 120 is discharged, because the pressure filter powder cup 140 is detachably arranged in the installation cavity 1320, when the cake-shaped coffee residue 30 needs to be discharged, by making the cup bottom of the pressure filter powder cup 140 facing the docking interface 1310, so that the filter holes 1410 are communicated to the outlet pipe 1210 of the pressure water 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 interface 1310 of the extraction holder 130 under the action of the pressure water pump 120, and the discharged air acts on the cake-shaped coffee residue 30 on the cup bottom of the filter powder cup through each filter hole 1410, while the cup opening of the pressure filter powder cup 140 faces and is communicated to the discharge port 1330, the cake-shaped coffee residue 30 is discharged from the discharge port 1330 of the extraction holder 130 under the pushing of the air, which is convenient and fast.

[0051] 3) Compared with the prior art portable electric pressure coffee machine, the pressure residue discharge mechanism 100 can be quickly and rapidly installed in the mounting cavity 1320 when the user needs to brew coffee by using the pressure filter cup 140, and the water in the pressure water pump 120 can be efficiently extracted through the cup opening of the pressure filter cup 140, and when the user needs to discharge the cake-shaped coffee residue 30, the user can quickly make the cup bottom of the pressure filter cup 140 face the docking port 1310, so that the air in the pressure water pump 120 can act on the cake-shaped coffee residue 30 through the filter holes 1410 of the cup bottom of the pressure filter cup 140 to achieve efficient residue discharge, which not only avoids the cumbersome process of manual residue discharge, but also makes the cake-shaped coffee residue 30 uniformly stressed and completely separated from the cup bottom of the pressure filter cup 140 through the filter holes 1410, so that the cup bottom of the pressure filter cup 140 can be quickly and completely cleaned.
