[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 This utility model provides a technical solution: a foldable and storable travel coffee machine, including a housing mechanism 1. The upper and lower sides of the housing mechanism 1 are provided with horizontally arranged guide grooves 101. An extension frame 3 is installed inside the guide grooves 101. There are two extension frames 3 in total.

[0026] Two protruding limiting sliders 301 are fixedly connected to each other on the front and rear sides of the two extension frames 3. The limiting sliders 301 are slidably connected in the guide groove 101. Magnetic blocks 3011 are also fixedly connected to the right end face of the two extension frames 3. Magnetic blocks 3011 are used to be attracted and connected to the housing mechanism 1. Foldable water bag assembly 3015 is also fixedly connected to the inner side of the two extension frames 3.

[0027] By setting guide grooves 101 on the upper and lower sides of the housing mechanism 1 and installing the extension frame 3, the extension frame 3 can be stably unfolded and stored by sliding in the guide grooves 101 with the limiting slider 301; the magnetic block 3011 is attracted to the housing mechanism 1 to fix the position of the extension frame 3; the foldable water bag assembly 3015 connected to the inside is convenient to store and can store water when unfolded to meet the water needs of the coffee machine, thus solving the problem of large size and inconvenient storage of some portable coffee machines after folding.

[0028] See Figures 1-5 The water bag assembly 3015 is used to store water, and an injection pipe 3012 is fixedly connected to the top surface of the extension frame 3 on the upper side. The injection pipe 3012 is in communication with the water bag assembly 3015.

[0029] The liquid injection tube 3012 at the top of the upper extension bracket 3 is connected to the water bag assembly 3015, making it convenient to inject water into the water bag assembly 3015. The operation is simple and convenient, improving the convenience of adding water when using the coffee machine.

[0030] See Figures 2-4 A drain pipe 3013 is fixedly connected to the left end face of the extension frame 3 located on the lower side. The drain pipe 3013 is connected to the water bag assembly 3015, and the injection pipe 3012 and the drain pipe 3013 are both screwed with plugs 3014.

[0031] The drain pipe 3013 at the left end of the lower extension frame 3 is connected to the water bag assembly 3015. Both the injection pipe 3012 and the drain pipe 3013 have plugs 3014. When drainage or leakage prevention is required, the water flow can be controlled by the plugs 3014 to ensure the sealing and drainage function of the coffee machine during use.

[0032] See Figures 5-6A door assembly 1011 is hinged to the front opening of the housing mechanism 1. A transparent acrylic plate is embedded inside the door assembly 1011. A handle assembly 1012 is also fixedly connected to the front surface of the door assembly 1011.

[0033] The door assembly 1011 is hinged to the front of the housing mechanism 1, and a transparent acrylic plate is embedded in the door to facilitate observation of the interior. The handle assembly 1012 at the front facilitates opening and closing the door, making the daily operation of the coffee machine more user-friendly.

[0034] See Figures 1-2 A battery 2 is fixedly connected to the top of the cavity opened at the front end of the housing mechanism 1. A charging port 201 is opened on the front end surface of the battery 2, and an extraction component 2011 is fixedly connected to the bottom end of the battery 2.

[0035] The battery 2 and charging port 201 at the top of the front cavity of the housing 1 provide power to the coffee machine, so that it does not need to rely on an external fixed power source and can be used flexibly while traveling; the extraction component 2011 connected to the bottom of the battery 2 is a key component for making coffee and ensures the integrity of the coffee machine's functions.

[0036] See Figures 3-5 An extraction tube 2012, which is inserted into the water bag assembly 3015, is fixedly connected to the left side of the outer peripheral surface of the extraction component 2011. An extraction pump 2013 is fixedly connected to the outside of the extraction tube 2012.

[0037] The extraction tube 2012 on the left side of the outer periphery of the extraction component 2011 is inserted into the water bag component 3015. With the help of the external extraction pump 2013, water in the water bag component 3015 can be drawn into the extraction component 2011 to achieve automatic water intake and provide a stable water supply for coffee extraction.

[0038] See Figures 1-5 The bottom of the extraction component 2011 is screwed with a tightening head 2014, and the bottom of the tightening head 2014 is fixedly connected to an extraction plate 2015 with filter holes. The cup body 2016 is placed inside the cavity opened at the front end of the housing mechanism 1.

[0039] The tightening head 2014 screwed to the bottom of the extraction component 2011 facilitates the installation and removal of the extraction tray 2015; the filter holes on the extraction tray 2015 can filter coffee grounds to ensure the quality of the brewed coffee; the cup body 2016 is placed in the front cavity of the housing mechanism 1 to receive the brewed coffee, thus improving the coffee machine's usage process.

[0040] Before using the coffee machine, first observe the location of the charging port 201. It is located on the front face of the battery 2, and the battery 2 is fixed to the top of the cavity at the front of the housing mechanism 1. Connect the external power source to the charging port 201 using the compatible charging cable to charge the battery 2, ensuring that the coffee machine has sufficient power for normal operation. After charging, grasp the handle assembly 1012 on the front face of the door assembly 1011 and pull it outward along the hinge point to open the door assembly 1011. At this time, you can clearly see the various components inside the housing mechanism 1. Next, prepare to unfold the extension frame 3. The extension frame 3 is located inside the guide groove 101 and is located on the upper and lower sides of the housing mechanism 1. There is one on each side. Hold the extension frame 3 with your hand. Since there are two protruding limiting sliders 301 fixedly connected to the front and rear sides of the extension frame 3, the limiting sliders 301 are tightly engaged with the guide groove 101. Therefore, when the extension frame 3 is pulled outward, the limiting sliders 301 will slide smoothly in the guide groove 101 along the lateral direction, ensuring that the extension frame 3 can only move in the direction of the guide groove 101, avoiding deviation or shaking. Continue to pull the extension frame 3 until it is extended to the appropriate position. At this time, the magnetic block 3011 on the right end face of the extension frame 3 will approach the housing mechanism 1 and generate an adsorption force with the housing mechanism 1, thereby fixing the extension frame 3 firmly in the current position and preventing it from sliding at will.

[0041] After the extension frame 3 is unfolded and secured, proceed with the water filling operation. Locate the injection tube 3012 located on the top surface of the upper extension frame 3. The injection tube 3012 is connected to the water bag assembly 3015, and a stopper 3014 is screwed into the inside of the injection tube 3012. Twist the stopper 3014 by hand to unscrew it from the injection tube 3012. At this point, the opening of the injection tube 3012 is open. Use a suitable water container, such as a mineral water bottle, to slowly pour water into the injection tube 3012. The water will flow down the injection tube. 3012 flows into the water bag assembly 3015. During the water filling process, the water volume can be roughly judged by observing the degree of expansion of the water bag assembly 3015. Since the water bag assembly 3015 has a folded structure, it will gradually expand as water is injected. When the water bag assembly 3015 expands to a near full state, or when it is judged from experience that the water volume is sufficient to make the required coffee, stop adding water. Then, screw the stopper 3014 back into the injection tube 3012 to make it fit tightly and prevent water leakage.

[0042] After adding water, open the door assembly 1011 to prepare for coffee making. Place an appropriate amount of coffee grounds evenly on the extraction tray 2015, which has filter holes. Its bottom end is screwed onto the extraction assembly 2011 via a tightening head 2014. After installing the coffee grounds, close the door assembly 1011 and start the extraction pump 2013. The extraction pump 2013 is fixed to the outside of the extraction tube 2012, one end of which is inserted into the water bag assembly 3015, and the other end is connected to the extraction assembly 2011. Once the extraction pump 2013 is started, it will generate suction. Water is drawn from the water bag assembly 3015 through the extraction tube 2012. Under the action of the extraction pump 2013, the water quickly flows into the extraction assembly 2011. Inside the extraction assembly 2011, the water comes into full contact with the coffee grounds placed on the extraction tray 2015, and the hot water begins to extract the coffee grounds. During the extraction process, soluble substances in the coffee grounds gradually dissolve in the water, forming coffee liquid. Because the bottom of the extraction tray 2015 has filter holes, the extracted coffee liquid drips down through these holes and eventually falls into the cup body 2016 placed in the front cavity of the housing mechanism 1.

[0043] After the coffee is brewed, first turn off the extraction pump 2013 to stop the water extraction and coffee extraction process. Then, reopen the door assembly 1011, hold the handle of the cup body 2016, and remove the cup body 2016 from the cavity at the front end of the housing mechanism 1 to enjoy the coffee. After enjoying the coffee, start cleaning the coffee machine. First, open the stopper 3014 on the drain pipe 3013 at the left end of the lower extension bracket 3. Turn the stopper 3014 by hand to separate it from the drain pipe 3013. At this time, the opening of the drain pipe 3013 is open, and the remaining water in the water bag assembly 3015 will flow out through the drain pipe 3013 under the action of gravity. After the water in 3015 is basically drained, close the stopper 3014 of the drain pipe 3013. Next, clean the coffee grounds remaining on the extraction tray 2015. Hold the tightening head 2014 and turn it counterclockwise to gradually separate the tightening head 2014 from the extraction component 2011, thereby removing the extraction tray 2015. Rinse the extraction tray 2015 with clean water to clean off the remaining coffee grounds. After cleaning, reinstall the extraction tray 2015 back into the extraction component 2011. Turn the tightening head 2014 clockwise to make it tightly connected to the extraction component 2011, ensuring that the extraction tray 2015 is securely installed.

[0044] After cleaning, begin storing the coffee machine. First, hold the extension rack 3 and push it towards the housing mechanism 1, overcoming the attraction between the magnetic block 3011 and the housing mechanism 1. Since the limiting slider 301 slides in the guide groove 101, the extension rack 3 will move smoothly inward along the guide groove 101. As the extension rack 3 retracts, the water bag assembly 3015 connected to its inner side will also gradually fold up to reduce space occupation. When the extension rack 3 is completely retracted, the magnetic block 3011 separates from the housing mechanism 1. Finally, close the door assembly 1011, hold the handle assembly 1012, and push the door assembly 1011 inward along the hinge point to close it, completing the storage process of the coffee machine for future use or carrying.

[0045] In summary, the device, by providing guide groove 101, can provide guidance for the unfolding of the extension frame 3.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
