[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] In one embodiment of the present invention, a coffee brewing device is provided, which can discharge heated gas to the brewing chamber 101 through the gas supply component 5 and the heating component 2, thereby achieving the purpose of drying the coffee grounds in the brewing chamber 101. A coffee brewing device according to an embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the coffee brewing device includes a brewing component 1, a heating component 2, a water supply component 3 and an air supply component 5. A brewing chamber 101 is formed in the brewing component 1. The heating component 2 has an inlet 201 and a discharge port 202, and the discharge port 202 of the heating component 2 is communicated with the brewing chamber 101. The water supply component 3 is connected to the inlet 201 of the heating component 2 through a first pipeline 4, and the liquid discharged from the water supply component 3 is heated by the heating component 2 and discharged to the brewing chamber 101. The air supply component 5 is connected to the inlet 201 of the heating component 2 through a second pipeline 6, and the first pipeline 4 and the second pipeline 6 are connected in parallel, and the gas discharged from the air supply component 5 is heated by the heating component 2 and discharged to the brewing chamber 101; wherein, the water supply component 3 and the air supply component 5 work independently.

[0029] It is understandable that the water supply component 3 can pressurize liquid such as water for brewing coffee and discharge it into the brewing chamber 101. Exemplarily, the water supply component 3 can be a water pump, and the water pump has a water inlet and a water outlet.

[0030] It is understandable that the air supply component 5 can pressurize air or other gases and discharge them into the brewing chamber 101. Exemplarily, the air supply component 5 can be an air pump, and the air pump has an air inlet and an air outlet.

[0031] Optionally, the coffee brewing device may further include a water tank 11 and a flow meter 13. The water tank 11 is connected to the water inlet of the water supply assembly 3. The flow meter 13 is disposed on a pipeline between the water tank 11 and the water inlet of the water supply assembly 3. The water tank 11 can stably provide water to the coffee brewing device to improve the brewing efficiency of the coffee brewing device. The flow meter 13 can measure the amount of water required to brew the coffee powder to accurately control the brewing effect of the coffee powder.

[0032] Optionally, the coffee brewing device may further include a fourth pipeline 14 and a safety valve 12. The fourth pipeline 14 is arranged between the first pipeline 4 and the second pipeline 6. The fourth pipeline 14 and the first pipeline 4 are connected in parallel, and the fourth pipeline 14 is provided with a safety valve 12. When the water pressure or air pressure in the coffee brewing device exceeds a preset pressure, the safety valve 12 can release the pressure in the pipeline in time, thereby effectively ensuring the safety and reliability of the coffee brewing device.

[0033] The water supply component 3 and the air supply component 5 work independently, which can be understood as follows: when the coffee brewing device is used to brew coffee, the water supply component 3 and the heating component 2 first complete the operation of brewing coffee, and then the air supply component 5 and the heating component 2 complete the operation of drying the coffee residue. The water supply component 3 and the air supply component 5 work independently to avoid interference between the two components and affect the working efficiency and reliability of the coffee brewing device.

[0034] In the above embodiment, the hot water heated by the heating component 2 can be discharged to the brewing chamber 101 so that the coffee powder in the brewing chamber 101 can be fully dissolved. After brewing is completed, the coffee brewing device can also heat the gas generated by the gas supply component 5 through the heating component 2 and discharge it into the brewing chamber 101, thereby improving the drying effect of the coffee residue generated after brewing coffee, effectively reducing the pollution caused by the undried coffee residue, and greatly facilitating the user's cleaning work after brewing coffee. In addition, the coffee brewing device can use a heating component 2 to heat the gas and liquid separately, effectively simplifying the mechanical structure of the coffee brewing device and reducing the processing difficulty and cost.

[0035] In some embodiments, the coffee brewing device also includes a control board, which is electrically connected to the heating component 2, the water supply component 3 and the gas supply component 5 respectively, and the control board is used to send a first opening instruction to the heating component 2 and the water supply component 3 to supply the heated liquid to the brewing chamber 101. The control board is also used to send a closing instruction to the water supply component 3 and a second opening instruction to the gas supply component 5 after supplying the heated liquid to the brewing chamber 101, so as to supply the heated gas to the brewing chamber 101.

[0036] In the above embodiment, the opening and closing of the heating component 2, the water supply component 3 and the air supply component 5 can be accurately controlled by the control panel to add hot water and hot air to the brewing chamber 101 respectively, thereby effectively improving the brewing efficiency and the efficiency of drying coffee residues, reducing the pollution caused by coffee residues, and improving the user experience.

[0037] Optionally, the coffee brewing device may further include a touch panel electrically connected to the control board, and the user may control the coffee brewing device by manipulating the touch panel.

[0038] After the control panel controls the water supply component 3 to supply a preset amount of hot water to the brewing chamber 101, as the drip coffee continues to be discharged, the pressure in the brewing chamber 101 will gradually decrease, causing the speed of the drip coffee to slow down. At this time, the control panel can start the air supply component 5 to blow air and pressurize the brewing chamber 101 to keep the pressure in the brewing chamber 101 basically unchanged, so that the last part of the coffee can be dripped and discharged smoothly. In this way, the hot air provided by the above-mentioned air supply component 5 can not only dry the coffee grounds, but also increase the drip speed of the coffee.

[0039] After opening the air supply assembly 5, the hot air entering the brewing chamber 101 first causes the waste liquid in the coffee grounds to be discharged into the waste water box through the discharge pipe under the action of air pressure, and then continues to provide hot air to the brewing chamber 101 to dry the coffee grounds. The dried coffee grounds are conducive to subsequent discharge and the cleanliness of the scraped grounds, reducing pollution and saving the time of automatic grounds discharge.

[0040] In some embodiments, Figure 1 As shown, the inlet 201 of the heating assembly 2 is connected to the third pipeline 7, and the coffee brewing device further comprises a connector 8, which has at least three interconnected connectors, and the at least three connectors are respectively connected to the first pipeline 4, the second pipeline 6 and the third pipeline 7.

[0041] In the above embodiment, the first pipeline 4 and the second pipeline 6 can be connected in parallel to the third pipeline 7 through the connecting piece 8, and connected to the heating component 2 through the third pipeline 7, so that the water supply component 3 and the gas supply component 5 can be connected in parallel with the heating component 2, so that the one heating component 2 is used to heat the liquid discharged by the water supply component 3 and the gas discharged by the gas supply component 5 respectively, while ensuring the use effect of the coffee brewing device, the internal mechanical structure is effectively simplified, thereby reducing the failure rate and manufacturing cost.

The transverse movement mechanism 102 can achieve stable cover or opening of the brewing chamber 101, and can allow the heated gas and liquid to enter the brewing chamber 101 through the through holes on the transverse movement structure.

[0047] Optionally, the brewing assembly 1 may include a first motor and a first transmission assembly, and the first motor may be connected to the transverse movement mechanism 102 through the first transmission assembly. For example, the first transmission assembly may include a gear rack mechanism, and the first motor may drive the transverse movement mechanism 102 to move in the transverse direction through the gear rack mechanism.

[0048] Optionally, the brewing chamber 101 may have an upper opening. Figure 3 The traverse mechanism 102 shown in FIG. 1 is in a state of opening the upper opening. Figure 4 The traverse mechanism 102 shown in FIG. 1 is in a state of covering the upper opening.

[0049] In some embodiments, Figures 2 to 8 As shown, the brewing assembly 1 further includes a vertical movement mechanism 103 disposed at the bottom of the brewing chamber 101, and the control board is electrically connected to the horizontal movement mechanism 102 and the vertical movement mechanism 103 respectively, and the control board is also used to control the horizontal movement mechanism 102 to open the brewing chamber 101, and after the vertical movement mechanism 103 moves upward, control the horizontal movement mechanism 102 to move in the direction of covering the brewing chamber 101.

[0050] Optionally, the brewing chamber 101 may have a lower opening, and the vertical movement mechanism 103 may block the lower opening of the brewing chamber 101. The vertical movement mechanism 103 may move up and down in the brewing chamber 101, and may specifically have a first position away from the upper opening of the brewing chamber 101 and a second position close to the upper opening of the brewing chamber 101. For example, Figure 3 The vertical movement mechanism 103 shown in FIG. 1 is in the first position. Figure 7 The vertical movement mechanism 103 shown in FIG. 1 is in the second position.

[0051] like Figures 3 to 8 shown. Figure 3The coffee brewing device shown in FIG. 1 is in a first working state, at which time the transverse movement mechanism 102 is in a state of opening the brewing chamber 101 , and the vertical movement mechanism 103 is in a first position, and coffee powder can enter the brewing chamber 101 through the upper opening of the brewing chamber 101 .
