Background Art

[0002] Portable electric coffee machines have developed rapidly in recent years. There are many electric coffee machines on the market. The electric coffee machine pumps water for supply, and the pumped water is used to brew coffee in the brewing head. Pumping water for supply can provide a certain water flow impact force. The common structure of the electric coffee machine on the market, such as the patent number 201810487027.6, named a portable coffee machine. When brewing coffee, one hand needs to hold the cup body and the other hand needs to hold the coffee cup. Since the electric coffee machine does not complete brewing in a few seconds during operation, it usually requires a process. Holding the brewing all the time by hand will cause inconvenience, especially when there is something urgent temporarily, the brewing may need to be interrupted.

Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a portable electric coffee machine with a simple structure, which does not need to be held by hand when brewing coffee and is convenient to use.

[0004] To solve the above problems, the utility model adopts the following technical solutions:

Specific Embodiment

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0021] Figures 1 to 6 As shown, a portable electric coffee machine convenient to use includes a body 1. The body 1 is approximately square-shaped. There is a water cavity 2 for filling water at the upper end of the body 1. The upper end of the water cavity 2 is open and is covered by a lid. The water cavity 2 is integrally formed with the body 1. There is a water outlet 11 at the lower end of the body 1. A water pump 4 capable of pumping water from the water cavity 2 to the water outlet 11 is provided inside the body 1. There is a pumping hole at the bottom of the water cavity 2. The pumping hole can be a mesh hole. The suction end of the water pump 4 is connected to the pumping hole. A head 3 capable of covering the water outlet 11 is connected to the lower end of the body 1. The water at the water outlet 11 flows into the head 3. There is a coffee accommodating cavity 31 for accommodating coffee and communicating with the water outlet 11 and a coffee outlet 32 communicating with the coffee accommodating cavity 31 inside the head 3. The coffee accommodating cavity 31 can be used to hold coffee powder or capsule coffee. In this embodiment, it is applicable to capsule coffee. A cup 5 capable of sleeving outside the body 1 and covering the head 3 is sleeved at the lower end of the body 1. When the head 3 is disassembled, the cup 5 is sleeved on the body 1. The lower end of the body 1 is close to the bottom wall of the cup 5. After the head 3 is installed, the cup 5 needs to move downward a certain distance to leave space for the head 3. The shapes of the cup 5 and the body 1 are roughly the same. In this embodiment, it is quadrilateral. The cup 5 is tightly sleeved outside the body 1. There is an upper-end open cavity 51 inside the cup 5. The upper-end opening of the cavity 51 is a non-circular opening. A non-circular support end 12 matching the opening of the cavity 51 is provided at the lower end of the body 1. The support end 12 is fixed to the bottom end of the body 1 by screws. Non-circular can refer to polygons, ellipses, waist shapes, etc. mainly to prevent them from being mismatched and sleeved after relative rotation. There is a support notch 13 on the support end 12. After the cup 5 is pulled out from the state of sleeving the body 1 and rotates a certain angle relative to the body 1, the support notch 13 presses against the edge of the opening of the cavity 51 to support the body 1. Due to the non-circular shape, the distances from the center to the edge are different. After relative rotation, the two cannot be completely sleeved together. After setting the support notch 13, it can be abutted and supported at the support notch 13. In this embodiment, the support end 12, the cavity 51 and its opening are quadrilateral. There are four support notches 13, which are respectively arranged at the corners of the quadrilateral. Of course, the quadrilateral is not an absolute quadrilateral, but has arc chamfers at the corners. When the cup 5 rotates 45° relative to the support end 12 (such as Figure 6As shown, the edges of the cavity 51 and the edges of the support end 12 cannot be aligned or flush, so they cannot be sleeved. Instead, the edge of the cup 5 will be stuck on the support notch 13, so that the cup 5 can support the body 1, and coffee can be brewed automatically without holding the body 1 by hand.

[0022] To prevent slipping, the side wall of the support notch 13 is provided with anti-slip convex lines 14 that can increase the friction with the inner wall of the cavity 51. The anti-slip convex lines 14 extend in the horizontal direction. Of course, the outer side walls of the support ends 12 are also provided with anti-slip convex lines 14.

[0023] To prevent the water flow at the water outlet 11 from being too fast, a connecting groove 15 is provided inside the support end 12. The machine head 3 is threadedly connected to the connecting groove 15. A strip-shaped groove 16 with a downward opening is provided inside the connecting groove 15. The strip-shaped groove 16 is a waist-shaped groove. The water outlet 11 is provided at one end of the strip-shaped groove 16 and communicates with the strip-shaped groove 16. A water guide cover 6 that can cover the opening of the strip-shaped groove 16 is provided inside the connecting groove 15. A water guide outlet 61 that is provided at the other end of the strip-shaped groove 16 and communicates with the strip-shaped groove 16 is provided on the water guide cover 6. The water guide outlet 61 is at the center of the water guide cover 6. When the water flows out, it is guided by the strip-shaped groove 16 and then flows out. A water inlet 33 that is opposite to the water guide outlet 61 is provided at the upper end of the coffee accommodating cavity 31. The depth of the connecting groove 15 gradually increases from the water outlet 11 to the water guide outlet 61, which can reduce the impact of the water flow, make the water flow more uniform, transfer the water flow to the middle, and make the water flow evenly into the coffee bin.

[0024] The strip-shaped groove 16 protrudes inside the connecting groove 15. A positioning groove 62 for inserting the strip-shaped groove 16 is provided on the water guide cover 6. The positioning groove 62 is a waist-shaped groove. After the machine head 3 is threadedly connected to the connecting groove 15, the machine head 3 presses the water guide cover 6 tightly against the top wall of the connecting groove 15, which can prevent water leakage and provide a seal. A concentric convex ring 64 is provided at the lower end of the water guide cover 6. A concentric annular groove 34 for inserting the convex ring 64 is provided at the upper end of the machine head 3, which improves the sealing performance.
