It is widely used in the fields of catering, home, office, etc. Existing coffee machines generally consist of a coffee machine body and an extraction container. The coffee powder in the extraction container is brewed by a water pump in the coffee machine to generate high-pressure water pressure to filter the coffee powder. However, since the coffee powder in the extraction container is brewed by the high-pressure water pressure of the water pump, the brewed coffee powder will be firmly adsorbed on the bottom of the extraction container to form a cake-like coffee grounds. When it is necessary to brew coffee again, the user needs to manually take out the cake-like coffee grounds from the extraction container. The process of taking out the cake-like coffee grounds is not only repetitive and cumbersome, but also difficult to clean the bottom of the extraction container.

[0004] However, when the above-mentioned coffee machine needs to perform a dregs discharge operation, it is first necessary to remove the extraction bracket from the brewing body, and then remove the filter press powder cup in the extraction bracket, and reinstall the filter press powder cup into the installation cavity with the bottom of the filter press powder cup facing the docking port, and finally reinstall the extraction bracket into its original position; and when the above-mentioned coffee machine needs to perform an extraction operation, it is first necessary to remove the extraction bracket from the brewing body, and then remove the filter press powder cup in the extraction bracket, and reinstall the filter press powder cup into the installation cavity with the cup mouth of the filter press powder cup facing the docking port, and finally reinstall the extraction bracket into its original position, which makes the process of switching between the extraction and dregs discharge modes of the above-mentioned coffee machine more cumbersome and complicated, thereby greatly reducing the convenience of use of the above-mentioned coffee machine.

[0045] like Figures 1 to 10 As shown, further, both ends of the funnel assembly 400 can be switchably connected to the water outlet 123 of the brewing assembly 100, and the funnel assembly 400 is provided with an extraction port 410, an extraction chamber 420 and a residue discharge port 430 which are connected in sequence, and a filter screen 451 of the funnel assembly 400 is located between the extraction chamber 420 and the residue discharge port 430, so that during the extraction operation, the filter screen 451 can filter the coffee powder; when extracting, the first end of the funnel assembly 400 is connected to the water outlet 123 of the brewing assembly 100, and the extraction port 410 is connected to the water outlet 123 of the brewing assembly 100; when discharging residue, the second end of the funnel assembly 400 is connected to the water outlet 123 of the brewing assembly 100, and the residue discharge port 430 is connected to the water outlet 123 of the brewing assembly 100, so that when the residue discharge operation is required, the user can use the funnel to remove the residue. The component 400 is removed from the brewing component 100 and the funnel component 400 is turned over so that the residue discharge port 430 faces the water outlet 123 of the brewing component 100, and then the funnel component 400 is installed back on the brewing component 100; when an extraction operation is required, the user removes the funnel component 400 from the brewing component 100 and turns the funnel component 400 so that the extraction port 410 faces the water outlet 123 of the brewing component 100, and then installs the funnel component 400 back on the brewing component 100. Compared with the coffee machine of the prior art, the pressure residue discharge structure 10 of the present disclosure does not need to take out the powder cup when switching between the residue discharge mode and the extraction mode. In this way, the process of switching between the extraction mode and the residue discharge mode of the pressure residue discharge structure 10 is convenient and quick, thereby making the above-mentioned pressure residue discharge structure 10 more convenient to use.

[0046] In this embodiment, when the extraction operation is required, first, coffee powder is placed on the filter 451, and then the extraction port 410 of the funnel assembly 400 is directed toward the water outlet 123 of the brewing assembly 100, and the first end of the funnel assembly 400 is installed at the water outlet 123 of the brewing assembly 100, so that the water outlet 123 of the brewing assembly 100 can be connected with the extraction port 410; then, a container for holding coffee liquid is placed directly below the residue discharge port 430 of the funnel assembly 400, and the water is turned on. By turning on the hydraulic assembly 200 and closing the air pressure assembly 300, the hydraulic assembly 200 can deliver high-pressure water to the extraction chamber 420 through the water outlet 123 of the brewing assembly 100 to extract the coffee powder in the extraction chamber 420, so that the water is fully mixed with the coffee powder and extracted to form coffee liquid, which is discharged from the residue discharge port 430 through the filter holes on the filter screen 451 and falls into the container for holding the coffee liquid; finally, when the coffee in the container for holding the coffee liquid reaches a preset amount, the hydraulic assembly 200 is turned off.

[0047] However, after the extraction operation, the coffee powder in the extraction chamber 420 will gather and be adsorbed on the filter 451 and form a cake-like coffee grounds. The cake-like coffee grounds will cause the filter holes on the filter 451 to be blocked, so that the cake-like coffee grounds in the extraction chamber 420 need to be cleared before the next coffee extraction. In one embodiment, when performing the residue discharge operation, first, the funnel assembly 400 is removed from the brewing assembly 100; then, the funnel assembly 400 is turned over so that the residue discharge port 430 of the funnel assembly 400 faces the water outlet 123 of the brewing assembly 100, and the second end of the funnel assembly 400 is installed at the water outlet 123 of the brewing assembly 100 so that the water outlet 123 of the brewing assembly 100 can be connected to the residue discharge port 430; then, a container for holding coffee grounds is placed directly opposite the extraction port 410 of the funnel assembly 400. At the bottom, the air pressure component 300 is turned on and the water pressure component 200 is turned off. The air pressure component 300 can then deliver the high-pressure gas to the extraction chamber 420 through the water outlet 123 of the brewing component 100, so that the high-pressure gas can pass through the filter holes on the filter 451 and act on the cake-like coffee grounds gathered and adsorbed on the filter 451; finally, the cake-like coffee grounds are completely discharged from the extraction port 410 of the funnel component 400 under the push of the high-pressure gas and fall into the container for holding the coffee grounds. After the discharge operation is completed, the air pressure component 300 is turned off.

[0048] In the pressure slag discharge structure 10, since both ends of the funnel assembly 400 can be switchably connected to the water outlet 123 of the brewing assembly 100, the funnel assembly 400 is provided with an extraction port 410, an extraction chamber 420 and a slag discharge port 430 which are connected in sequence, and the filter screen 451 of the funnel assembly 400 is located between the extraction chamber 420 and the slag discharge port 430. When extracting, the first end of the funnel assembly 400 is connected to the water outlet 123 of the brewing assembly 100, and the extraction port 410 is communicated with the water outlet 123 of the brewing assembly 100. When discharging slag, the second end of the funnel assembly 400 is connected to the water outlet 123 of the brewing assembly 100, and the slag discharge port 430 is communicated with the water outlet 123 of the brewing assembly 100, so that when the slag discharge operation is required, the user can simply remove the funnel assembly 400 from the water outlet 123 of the brewing assembly 100. 0 The funnel assembly 400 is removed from the brewing assembly 100 and turned over, so that the residue discharge port 430 faces the water outlet 123 of the brewing assembly 100, and then the funnel assembly 400 is installed back on the brewing assembly 100; when the extraction operation is required, the user removes the funnel assembly 400 from the brewing assembly 100 and turns over the funnel assembly 400, so that the extraction port 410 faces the water outlet 123 of the brewing assembly 100, and then the funnel assembly 400 is installed back on the brewing assembly 100. Compared with the coffee machine of the prior art, the pressure residue discharge structure 10 of the present disclosure does not need to take out the powder cup when switching between the residue discharge mode and the extraction mode, so that the process of switching between the extraction mode and the residue discharge mode is convenient and quick, thereby making the pressure residue discharge structure 10 have good convenience of use.

The control component 700 is also electrically connected to the diaphragm pump 320 and the air pressure solenoid valve 330, respectively, so that when an extraction operation is required, the control component 700 can control the air pressure solenoid valve 330 and the diaphragm pump 320 to be in a closed state, and control the pressure water pump 220 and the water pressure solenoid valve 230 to be in an open state; and when a slag discharge operation is required, the control component 700 can control the pressure water pump 220 and the water pressure solenoid valve 230 to be in a closed state, and control the air pressure solenoid valve 330 and the diaphragm pump 320 to be in an open state, so that the pressure slag discharge structure 10 is more convenient to use. In this embodiment, the control component 700 is a PLC controller.

[0053] like Figure 1 , Figure 3 and Fig. 9 As shown, in one embodiment, the brewing component 100 further includes a three-way pipe 500 and a connecting main pipe 600, and both ends of the connecting main pipe 600 are respectively connected to the water outlet 123 of the brewing component 100 and the first connecting port of the three-way pipe 500, the pressure water pump 220 is connected to the second connecting port of the three-way pipe 500 through the water pressure output pipe 210, and the diaphragm pump 320 is connected to the third connecting port of the three-way pipe 500 through the air pressure output pipe 310, so that the high-pressure water delivered by the pressure water pump 220 or the high-pressure gas delivered by the diaphragm pump 320 can be delivered to the connecting main pipe 600 through the three-way pipe 500, so that the connecting main pipe 600 can deliver the high-pressure gas or high-pressure water to the water outlet 123 of the brewing component 100.

[0054] like Fig. 9 As shown, in this embodiment, the water pressure output pipe 210, the air pressure output pipe 310, the three-way pipe 500 and the connecting main pipe 600 can be stainless steel hoses, high temperature and high pressure water pipes and steel high pressure pipes, so that the water pressure output pipe 210, the air pressure output pipe 310, the three-way pipe 500 and the connecting main pipe 600 can have good high temperature and high pressure resistance.

[0055] like Figure 1 and Fig. 9 As shown, in one embodiment, the brewing assembly 100 includes a body 110 and a brewing head 120.

The hydraulic assembly 200 and the air pressure assembly 300 are both arranged in the body 110 to protect the hydraulic assembly 200 and the air pressure assembly 300, so as to avoid the hydraulic assembly 200 or the air pressure assembly 300 from being damaged or even destroyed due to external factors, thereby extending the service life of the above-mentioned pressure slag discharge structure 10.

[0056] like Figure 4 and Fig. 9 As shown, in this embodiment, a diverter plate 124 is fixedly connected below the water outlet 123 of the brewing head 120, and a plurality of diverter holes 124a are evenly opened on the surface of the diverter plate 124. When extracting, the water outlet 123 is connected to the extraction port 410 through the diverter holes 124a, so that the high-pressure water can evenly fall into the extraction chamber 420 through the diverter holes 124a, so that the coffee powder in the extraction chamber 420 can fully contact with the water and be extracted, thereby greatly improving the extraction effect of the pressure residue discharge structure 10; when discharging residue, the water outlet 123 is connected to the residue discharge port 430 through the diverter holes 124a, so that the diverter holes 124a and the filter holes of the filter screen 451 can evenly disperse the high-pressure gas, and at the same time can also reduce the impact force and flow rate of the high-pressure gas, so that the thrust of the cake-shaped coffee residue in the extraction chamber 420 is more uniform, so that the high-pressure gas can push the cake-shaped coffee residue out of the extraction port 410 more smoothly and completely.

[0057] like Figure 1 and Fig. 9As shown, in this embodiment, the machine body 110 and the brewing head 120 jointly form an installation cavity 130, and the hydraulic component 200, the air pressure component 300, the three-way pipe 500 and the connecting main pipe 600 are all arranged in the installation cavity 130 to protect the hydraulic component 200 and the air pressure component 300, so as to avoid the hydraulic component 200 or the air pressure component 300 from being damaged or even destroyed due to external factors, thereby extending the service life of the pressure residue discharge structure 10; the water outlet 123 is opened at the bottom of the brewing head 120 to ensure that during the extraction operation, the high-pressure water can smoothly flow into the extraction chamber 420 and extract the coffee in the extraction chamber 420. At the same time, during the residue discharge operation, the thrust of the high-pressure gas is in the same direction as the gravity direction of the cake-shaped coffee residue, so that the pressure residue discharge structure 10 can more easily discharge the cake-shaped coffee residue from the extraction port 410, thereby improving the residue discharge effect of the pressure residue discharge structure 10.

[0058] like Figures 1 to 8 As shown, in one embodiment, the funnel assembly 400 includes a funnel bracket 440 and a filter press bowl 450. The two ends of the funnel bracket 440 can be switchably connected to the water outlet 123 of the brewing head 120. The extraction port 410, the extraction chamber 420 and the residue discharge port 430 are all opened in the funnel bracket 440. The filter press bowl 450 is installed and fixed in the extraction chamber 420. The bottom of the filter press bowl 450 is a filter screen 451. The bottom of the filter press bowl 450 is arranged toward the extraction port 410. The outer peripheral wall of the filter press bowl 450 is sleeved with a first sealing rubber ring 452. The inner side edge of the first sealing rubber ring 452 is connected to the filter press bowl 451. 0 is in interference fit with the outer wall of the first sealing rubber ring 452, and the outer side edge of the first sealing rubber ring 452 is in interference fit with the inner wall of the filter press bowl 450, so that the filter press bowl 450 is limited and fixed in the extraction chamber 420; at the same time, during the residue discharge operation, the cake-like coffee residues block the filter holes at the bottom of the filter press bowl 450, and the first sealing rubber ring 452 blocks the gap between the outer wall of the filter press bowl 450 and the inner wall of the extraction chamber 420, so that the bottom of the filter press bowl 450 and the bottom of the brewing head 120 form a sealed cavity together, so that the high-pressure gas can push the cake-like coffee residues in the filter press bowl 450 out of the extraction port 410.

[0059] like Figure 3 to Figure 4 As shown, in the present embodiment, a first positioning groove 421 is further formed on the inner peripheral wall of the extraction chamber 420, and a first sealing rubber ring 452 is installed and fixed in the first positioning groove 421, so that the first sealing rubber ring 452 can be fixed in the first positioning groove 421, thereby avoiding the first sealing rubber ring 452 sliding relative to the funnel assembly 400 due to excessive thrust on the filter press bowl 450 during the extraction or slag discharge process, so that the first sealing rubber ring 452 can more securely limit and fix the filter press bowl 450 in the extraction chamber 420, thereby greatly improving the reliability of the pressure slag discharge structure 10.

[0060] like Figures 6 to 8 As shown, in one embodiment, at least one buckle is protruding from both ends of the funnel bracket 440, a first buckle 441 is protruding from the outer peripheral wall of the first end of the funnel bracket 440, and a second buckle 442 is protruding from the outer peripheral wall of the second end of the funnel bracket 440, and an inner side wall of the water outlet 123 of the brewing head 120 is formed with a clamping groove 121 adapted to the first buckle 441 and the second buckle 442. By screwing the funnel bracket 440, the first buckle 441 and the second buckle 442 can be clamped and fixed to the clamping groove 121, so that both ends of the funnel bracket 440 can be removed or fixed to the inner side wall of the water outlet 123 of the brewing head 120 by screwing, so as to facilitate the removal or installation of the funnel bracket 440, thereby improving the convenience of use of the above-mentioned pressure slag discharge structure 10.

[0061] like Figure 6 to Figure 7 As shown, in this embodiment, the first buckle 441 and the second buckle 442 are both integrally formed with the funnel bracket 440 to improve the overall compactness of the funnel bracket 440 .

[0062] like Figures 3 to 6 As shown, in one of the embodiments, the mouth of the filter press powder bowl 450 is bent and extended outward to form a bending portion 453, and the bending portion 453 and the outer peripheral edge of the filter press powder bowl 450 form a limiting groove 453a, and the outer peripheral edge of the first end of the funnel bracket 440 abuts against the inner wall of the limiting groove 453a, so that the filter press powder bowl 450 is limited and fixed in the extraction chamber 420, avoiding the filter press powder bowl 450 from sliding relative to the funnel assembly 400 during extraction or slag discharge, ensuring that the pressure slag discharge structure 10 can be used normally, thereby further improving the reliability of the pressure slag discharge structure 10.

[0063] like Figures 3 to 6 As shown, in this embodiment, the mouth of the filter press bowl 450 and the extraction port 410 are on the same horizontal line, so that the mouth of the filter press bowl 450 can be tightly attached to the brewing head 120, ensuring that during the extraction operation, there is good sealing between the filter press bowl 450 and the bottom of the brewing head 120, so that the extraction effect of the above-mentioned pressure slag discharge structure 10 can be further improved.

[0064] like Figures 3 to 5As shown, in one embodiment, the inner side wall of the brewing head 120 is further formed with a mounting groove 122, and the mounting groove 122 is arranged around the water outlet 123 of the brewing head 120. A second sealing rubber ring 122a is arranged in the mounting groove 122, and the second sealing rubber ring 122a is arranged opposite to the outer peripheries of both ends of the funnel bracket 440. When extracting, the first end of the funnel bracket 440 is installed at the water outlet 123 of the brewing head 120, and the bent portion 453 is in interference contact with the second sealing rubber ring 122a. When discharging slag, the outer periphery of the second end of the funnel bracket 440 is in interference contact with the second sealing rubber ring 122a, so as to ensure that during the extraction or slag discharging process, the brewing head 120 and the filter press bowl 450 can have a good seal, thereby improving the extraction effect and slag discharging effect of the pressure slag discharging structure 10.

[0065] like Figures 3 to 7 As shown, in one embodiment, a handle 443 is protrudingly provided on the outer peripheral wall of the funnel bracket 440, and avoidance areas 443a are formed on both sides of the handle 443 adjacent to the funnel bracket 440. The avoidance areas 443a are arranged opposite to the side walls at the water outlet 123 of the brewing head 120, so as to avoid the difficulty in installing the funnel bracket 440 due to the mutual obstruction between the side walls at the water outlet 123 of the brewing head 120 and the handle 443 when the funnel bracket 440 and the brewing head 120 are assembled, thereby further improving the convenience of use of the pressure slag discharge structure 10.

[0066] like Figure 6 to Figure 7 As shown, in this embodiment, the handle 443 and the funnel support 440 are an integrally formed structure to improve the overall compactness of the funnel support 440.

The guiding direction of the first guiding slope 441a is opposite to the guiding direction of the second guiding slope 442a, so that the screwing direction in which the first end of the funnel bracket 440 is fixed in the clamping groove 121 by the guiding screwing of the first guiding slope 441a is consistent with the screwing direction in which the second end of the funnel bracket 440 is fixed in the clamping groove 121 by the guiding screwing of the second guiding slope 442a, so that the user can quickly install the funnel assembly 400 on the brewing head 120 without paying special attention to the screwing direction, thereby reducing the possibility of installation misalignment and simplifying the installation process.

[0068] like Figures 5 to 8As shown, in this embodiment, the first buckle 441 and the second buckle 442 are both wedge-shaped structures, so that the first buckle 441 and the second buckle 442 can fit tightly against the inner wall of the clamping groove 121, thereby preventing the funnel bracket 440 from loosening or falling off when it is installed on the brewing head 120.

[0069] like Figures 3 to 5 As shown, in one embodiment, the funnel assembly 400 also includes a powder bowl retaining spring 460, which is sleeved on the outer peripheral wall of the filter press powder bowl 450, and the inner side edge of the powder bowl retaining spring 460 is limitedly abutted against the outer peripheral wall of the filter press powder bowl 450, and the outer side edge of the powder bowl retaining spring 460 is limitedly abutted against the inner peripheral wall of the extraction chamber 420, so as to limit and fix the filter press powder bowl 450 in the extraction chamber 420, so as to avoid the filter press powder bowl 450 sliding relative to the funnel assembly 400 during extraction or slag discharge, thereby ensuring that the pressure slag discharge structure 10 can be used normally, and further improving the reliability of the pressure slag discharge structure 10.

[0070] like Figures 3 to 5 As shown, in the present embodiment, a second positioning groove 422 is further provided on the inner wall of the extraction chamber 420, and a powder bowl retaining spring 460 is arranged in the second positioning groove 422 so that the powder bowl retaining spring 460 can be fixed in the second positioning groove 422, thereby preventing the powder bowl retaining spring 460 from sliding relative to the funnel assembly 400 due to excessive thrust applied to the filter press powder bowl 450 during the extraction or slag discharge process, so that the powder bowl retaining spring 460 can more securely limit the filter press powder bowl 450 in the extraction chamber 420, thereby further improving the reliability of the pressure slag discharge structure 10.

The funnel assembly 400 is removed from the brewing assembly 100 and turned over, so that the residue discharge port 430 faces the water outlet 123 of the brewing assembly 100, and then the funnel assembly 400 is installed back on the brewing assembly 100; and when an extraction operation is required, the user removes the funnel assembly 400 from the brewing assembly 100 and turns over the funnel assembly 400, so that the extraction port 410 faces the water outlet 123 of the brewing assembly 100, and then the funnel assembly 400 is installed back on the brewing assembly 100. Compared with the coffee machine of the prior art, the pressure residue discharge structure 10 of the present disclosure does not need to take out the powder cup when switching between the residue discharge and extraction modes.
