[0027] See Figure 1 and Figure 2 , a coffee machine, comprising a cup body 1 and a brewing cup 2 detachably connected to the lower end of the cup body 1. At least one battery chamber 11 is provided inside the cup body 1. The bottom of the battery chamber 11 is open, and the opening of the battery chamber 11 is located on the bottom surface of the cup body 1. A battery 12 for power supply is placed in the battery chamber 11. A charging port 13 for charging the battery 12 is provided on the outer side of the cup body 1. A DC power interface 14 is also provided on the outer side of the cup body 1. A battery cover 15 for covering the opening of the battery chamber 11 is movably provided on the bottom surface of the cup body 1. Among them, the charging port 13 is a type-c charging port or a USB charging port.

[0028] When the battery 12 needs to be replaced, first remove the brewing cup 2 from the lower end of the cup body 1, then open the battery cover 15 to expose the battery cavity 11, and then the battery 12 in the battery cavity 11 can be taken out and a new battery 12 can be installed. On the basis of originally charging the built-in battery 12 of the coffee machine through a dedicated charging port and connecting to the cigarette lighter of a car through a DC power interface, this coffee machine adds a way of detachable battery replacement, so that users don't have to worry about the location of the power socket or whether they have brought a charger. Users can purchase additional batteries as spares, avoiding being restricted in scenarios without power supply, ensuring that there is enough power to make coffee at any time, especially suitable for users who need to work or travel outdoors for a long time; users can purchase additional batteries as spares to ensure that there is enough power to make coffee at any time, avoiding battery life anxiety. By replacing the battery, users can quickly resume using the coffee machine without waiting for a long time to charge, which is applicable to scenarios where multiple cups of coffee need to be made continuously or in high-intensity use; since the battery is replaceable, when the battery performance deteriorates, users can choose to replace the new battery instead of the whole coffee machine, which helps to extend the service life of the coffee machine and reduce waste. Moreover, when the battery life ends, users can recycle or dispose of it instead of discarding the whole coffee machine, which helps to reduce electronic waste and promote an environmentally friendly and sustainable lifestyle.

[0029] In this embodiment, there are three battery cavities 11, and each battery cavity 11 contains a battery 12. The adjacent two battery cavities 11 are connected, which is convenient for the processing and forming of the battery cavity 11. Actually, the number of the battery cavities 11 and the batteries 12 is not limited, and more or fewer battery cavities 11 and batteries 12 can be set.

[0030] In this embodiment, as Figures 1 to 3 shown, the battery cover 15 is hinged to the bottom surface of the cup body 1. The battery cover 15 can be flipped relative to the cup body 1 to open or cover the opening of the battery cavity 11. A latch 151 is provided on one side of the battery cover 15, and a latch hole 16 adapted to the latch 151 is provided at the bottom of the cup body 1. When the battery cover 15 covers the opening of the battery cavity 11, the latch 151 is snapped into the latch hole 16. The settings of the latch 151 and the latch hole 16 make it impossible for the battery cover 15 to flip relative to the cup body 1 after covering the opening of the battery cavity 11, thus preventing the battery 12 from loosening and affecting the use of the coffee machine.

[0031] Preferably, referring to Figures 1 to 3 , the latch 151 is an elastic tongue. When the battery cover 15 covers the opening of the battery cavity 11, the elastic tongue is snapped into the latch hole 16; when the battery cover 15 needs to be opened, the elastic tongue is moved out of the latch hole 16, and then the battery cover 15 can be flipped to expose the opening of the battery cavity 11.

[0032] Preferably, in order to facilitate the movement of the elastic tongue, the bottom surface of the elastic tongue is concave to form a groove 152, and the elastic tongue is driven to escape from the hole 16 by moving the groove 152. The user can put the fingertip into the groove 152 and move it in the opposite direction of the hole 16 to drive the elastic tongue to escape from the hole 16, so as to open the battery cover 15, which is more convenient to use.

[0033] In this embodiment, the battery cover 15 hinged on the bottom surface of the cup body 1 can rotate relative to the bottom surface of the cup body 1 with a horizontal rotation axis as the axis; in other embodiments, the battery cover 15 is horizontally rotatably arranged on the bottom surface of the cup body 1 and rotates with a vertical rotation axis as the axis. When the battery cover 15 needs to be opened to expose the opening of the battery cavity 11, the battery cover 15 is horizontally rotated to a position offset from the opening of the battery cavity 11. When the battery cover 15 needs to be closed to cover the opening of the battery cavity 11, the battery cover 15 is horizontally rotated to a position facing the opening of the battery cavity 11. Regardless of whether the battery cover 15 is opened or closed, the battery cover 15 always remains on the same horizontal plane; or, the battery cover 15 is slidably arranged on the bottom surface of the cup body 1, and the opening of the battery cavity 11 can be exposed or covered by sliding the battery cover 15.

[0034] Preferably, see Figure 2 The top surface of the battery cover 15 is provided with a limiting groove 153 that matches the shape of the lower end of the battery 12. When the battery cover 15 covers the opening of the battery cavity 11, the lower end of the battery 12 is located in the limiting groove 153. The setting of the limiting groove 153 allows the lower end of the battery 12 to be restricted in the limiting groove 153 after the battery cover 15 is closed, which can prevent the battery 12 from shaking or moving, thereby ensuring that the battery 12 can supply power normally.

[0035] Preferably, see Figure 1 and Figure 4 The cup body 1 and the brewing cup 2 are detachably connected as follows: a slide groove 17 is provided on the outer wall of the bottom of the cup body 1, and the slide groove 17 is L-shaped. A ring-shaped clamping ring 21 is provided on the top of the brewing cup 2, and a slider 211 is provided on the inner wall of the clamping ring 21. The slider 211 slides through the vertical section of the slide groove 17 to the horizontal section of the slide groove 17 so that the slider 211 is clamped in the horizontal section of the slide groove 17. When the brewing cup 2 needs to be installed at the lower end of the cup body 1, first align the slider 211 with the vertical section of the slide groove 17, push the brewing cup 2 upward or push the cup body 1 downward to make the slider 211 slide to the uppermost end of the vertical section of the slide groove 17, and then rotate the brewing cup 2 or the cup body 1 horizontally to make the slider 211 slide to the end of the horizontal section of the slide groove 17 away from the vertical section, and the installation of the brewing cup 2 is completed; when removing the brewing cup 2, first rotate the brewing cup 2 or the cup body 1 horizontally to make the slider 211 slide from the horizontal section of the slide groove 17 to the uppermost end of the vertical section of the slide groove 17, and then pull out the brewing cup 2 downward or pull out the cup body 1 upward to complete the removal of the brewing cup 2.

[0036] like Figure 5, in this embodiment, a water chamber 18 and a water pump 19 are provided inside the cup body 1. The water chamber 18 is separated from the battery chamber 11. The water chamber 18 is used for placing water. The battery 12 powers the water pump 19. A brewing chamber 22 is provided inside the brewing cup 2. Coffee powder or coffee capsules are placed in the brewing chamber 22. The water chamber 18 is communicated with the water inlet end of the water pump 19 through a first pipeline 3. The water outlet end of the water pump 19 is communicated with the brewing chamber 22 through a second pipeline 4. The water in the water chamber 18 is supplied to the brewing chamber 22 by using the water pump 19, the first pipeline 3 and the second pipeline 4 to brew the coffee in the brewing chamber 22.

[0037] Preferably, referring to Figure 1 , an avoidance opening 154 is provided on one side of the battery cover 15. The second pipeline 4 passes through the avoidance opening 154. The provision of the avoidance opening 154 provides space for the second pipeline 4 and avoids interference with the second pipeline 4 when the battery cover 15 is closed.

[0038] Preferably, referring to Figure 5 , the water chamber 18 is located in the upper part of the cup body 1, and the battery chamber 11 and the water pump 19 are both located in the lower part of the cup body 1, and the water pump 19 is located on one side of the battery chamber 11. Generally, a portable coffee machine has a relatively small volume. By arranging the water chamber 18 in the upper part of the cup body 1, the battery chamber 11 and the water pump 19 in the lower part of the cup body 1, and the water pump 19 on one side of the battery chamber 11, the components inside the cup body 1 can be made more compact, effectively saving space and avoiding the inconvenience of carrying caused by the overly large volume of the coffee machine.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
