Detailed Description of the Embodiment

[0023] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0024] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the accompanying drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present utility model can be more thoroughly understood and the scope of the present utility model can be fully conveyed to those skilled in the art.

[0025] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0026] Below, reference is made to Figure 1 to describe in detail the implementation of the coffee brewing device proposed according to the embodiments of the present utility model.

[0027] The coffee brewing device according to the embodiments of the present utility model includes: a first housing 1, and a high-temperature furnace 2, two water pumps 3, an overpressure protection switch 4, and a powder tray 5 installed on the first housing 1.

[0028] Specifically, the high-temperature furnace 2 is adapted to heat cold water; the powder tray 5 has a brewing space, and coffee powder is placed in the brewing space; the two water pumps 3 are connected to the high-temperature furnace 2 and the powder tray 5 to pump the hot water in the high-temperature furnace 2 into the brewing space, so as to generate pressure in the brewing space and brew the coffee powder; the overpressure protection switch 4 is connected to the powder tray 5 to adjust the pressure in the brewing space.

[0029] That is to say, during the coffee brewing process, the water heated by the high-temperature furnace 2 needs to be pumped into the brewing space of the powder tray 5 filled with coffee powder through the water pump 3, so as to form a certain pressure in the brewing space to brew the coffee powder. As hot water is continuously injected into the brewing space, the pressure in the brewing space will gradually increase. The overpressure protection switch 4 can detect the pressure in the brewing space. When the pressure in the brewing space exceeds the set value, the overpressure protection switch 4 exhausts and relieves the pressure in the brewing space, so that the pressure in the brewing space is maintained within the set range for brewing, thereby improving the brewing quality of coffee.

[0030] Thus, the double water pumps 3 are used to increase the water pressure in the brewing space of the powder tray 5 for injecting hot water, so as to generate sufficient pressure in the brewing space to brew the coffee powder. The overpressure protection switch 4 is used to adjust the pressure in the powder tray 5, so that the pressure in the powder tray 5 is stabilized within the set range, thus ensuring the quality of coffee brewing. The coffee brewing device has a simple structure, can accurately control the brewing pressure, and has a good brewing effect.

[0031] For the powder tray 5, the powder tray 5 includes a connecting seat 51 and a chuck 52. The connecting seat 51 is connected to the chuck 52 to jointly construct the brewing space. The connecting seat 51 is connected to two water pumps 3 and an overpressure protection switch 4. It can be understood that through the setting of the connecting seat 51, it is convenient for the water pumps 3 and the overpressure protection switch 4 to communicate with the brewing space, so that the water pump 3 can pump the hot water in the high-temperature furnace 2 into the brewing space jointly constructed by the connecting seat 51 and the chuck 52 to form pressure, and the overpressure protection switch 4 can detect the pressure in the brewing space and relieve the pressure after overpressure, thereby facilitating the brewing of coffee powder within the set pressure value. Among them, the powder tray 5 is detachably connected to the first housing 1, which is convenient for disassembling the powder tray 5 to put coffee powder. A sealing ring can be provided between the connecting seat 51 and the chuck 52, and the connecting seat 51 and the chuck 52 can be fixedly connected by screws. Three through holes communicating with the stamping space can be provided on the connecting seat 51. The water outlets of the two water pumps 3 communicate with two of the through holes, and the overpressure protection switch 4 communicates with the other through hole.

[0032] For the discharge of the brewed coffee, a discharge assembly 6 is further included. The discharge assembly 6 has a water distribution head 61 and a water outlet head 62. The water distribution head 61 is connected to the chuck 52 to divert the brewed coffee in the brewing space to the water outlet head 62 through the water distribution head 61. The water outlet head 62 is connected to the water distribution head 61 to further divert and discharge the diverted coffee. It can be understood that through the setting of the water distribution head 61, the brewed coffee can be dispersed and flowed to the water outlet head 62, and then the coffee is further dispersed and discharged through the water outlet head 62. Thus, during the process of the coffee passing through the water outlet head 62 and the water distribution head 61, it can be further dispersed and flow into the container, which is convenient for the full mixing of coffee and water. A filter screen can be provided between the powder tray 5 and the discharge assembly 6 to facilitate the filtration of impurities in the brewed coffee and then discharge it into the container.

[0033] For the placement of the container for receiving the brewed coffee, a chassis 7 is further included. The chassis 7 is installed on the first housing 1 to place the container for receiving the brewed coffee. It can be understood that through the setting of the chassis 7, it is convenient to place the container on the chassis 7 to receive the brewed coffee. Among them, a water drain tray 71 can be provided on the chassis 7 to facilitate the collection of the coffee leaking out of the container on the chassis 7, thus maintaining the hygiene of use.

[0034] For the cover of the high-temperature furnace 2, it further includes a shielding component 8. The cover member has a gasket 81 and a cover body 82. The gasket 81 is adapted to be connected to the open end of the high-temperature furnace 2, and the cover body 82 is connected to the gasket 81 to seal the open end of the high-temperature furnace 2. Understandably, the gasket 81 and the cover body 82 are provided to facilitate the sealing of the open opening of the high-temperature furnace 2, thereby preventing dust and other sundries from entering the high-temperature furnace 2 and ensuring the hygiene of the water quality.

[0035] For the cover body 82 and the gasket 81, the cover body 82 and the gasket 81 are magnetically connected. Understandably, the magnetic connection between the cover body 82 and the gasket 81 facilitates the quick opening of the cover body 82, thereby facilitating the cleaning of the high-temperature furnace 2 and ensuring the hygiene of the water quality. Among them, the gasket 81 can be made of metal material, and magnets can be installed on the cover body 82.

[0036] For the fixation of the water pump 3 and the connecting pipe, it further includes a first limiting plate 9. The first limiting plate 9 has a limiting hole 91 for limiting the protruding part at the top of the water pump 3, and a pipe-passing hole 92 through which the connecting pipe between the high-temperature furnace 2 and the water pump 3 can pass. Understandably, since the water pump 3 has a certain length, the setting of the limiting hole 91 of the first limiting plate 9 facilitates the limiting and fixation of the top of the water pump 3, thereby preventing the water pump 3 from shaking during operation and facilitating the improvement of the stability of the water output of the water pump 3; through the setting of the pipe-passing hole 92, the connecting pipe connecting the water pump 3 and the high-temperature furnace 2 can be limited and fixed, so that the connecting pipes are more neatly and beautifully distributed. Among them, a tee can be connected to the water outlet of the high-temperature furnace 2, and the water inlets of the two water pumps 3 are connected to the tee through connecting pipes.

[0037] For the fixation of the first housing 1, it further includes a second housing 10. The second housing 10 is connected to the back of the first housing 1 to support the first housing 1, and the second housing 10 is hollow inside. Understandably, the setting of the second housing 10 facilitates the installation and fixation of the first housing 1, and the hollow setting of the second housing 10 facilitates the arrangement of the wires and connecting pipes inside the first housing 1, so that the connecting pipes and wires are more neatly and beautifully distributed. Among them, the second housing 10 can be directly placed on the tabletop, or the second housing 10 can be fixed on the wall.

[0038] For the second housing 10, the second housing 10 includes a riser 101, an upper cover 102 and a base 103. The riser 101 is connected to the first housing 1 and is hollow inside.
