[0040] Handheld coffee machines allow people to conveniently enjoy coffee outdoors, while traveling, or in a car, meeting user needs. Internally, handheld coffee machines contain a water tank, a support assembly, and a control panel for operating the machine. In related technologies, the water tank consists of a body and a mounting frame. Assembly requires first fixing the body to the frame with screws, and then fixing the entire water tank to the support assembly with screws. This assembly process necessitates multiple screwing operations, resulting in low assembly efficiency and high labor and material costs.

[0041] To address the aforementioned technical problems, this application proposes a handheld coffee machine 100 with a quick-release water tank.

[0042] Reference Figures 1 to 3 In one embodiment of this application, the handheld coffee machine 100 with a quick-release water tank includes a water tank 20 and a support assembly 50. The water tank 20 includes a body 21 and a water tank frame 23. The water tank frame 23 has an internal mounting cavity 2311, and the body 21 is fixed within the mounting cavity 2311. The support assembly 50 is located at the bottom of the water tank 20, and the water tank frame 23 and the support assembly 50 are detachably connected by a snap-fit ​​mechanism.

[0043] A handheld coffee machine 100 with a quick-release water tank includes a housing 10, a support assembly 50, and a water tank 20, all housed inside the housing 10. The housing 21 is made of stainless steel and is approximately cylindrical in shape. The water tank holder 23 can be injection molded from engineering plastic. The shape of the mounting cavity 2311 matches the outer shape of the housing 21. When the housing 21 is inserted into the mounting cavity 2311, the two can be secured using interference fit, adhesive bonding, or auxiliary fasteners.

[0044] The support assembly 50 is fixed to the housing 10. The support assembly 50 includes a first support frame and a second support member, wherein the second support frame is located at the bottom of the first support frame, i.e., the first support member is connected to the water tank frame 23. Specifically, the water tank frame 23 is snap-fitted to the top of the first support frame. Understandably, the snap-fit ​​connection method includes, but is not limited to, elastic snaps, rotary snaps, or press-type snaps.

[0045] In this utility model, a handheld coffee machine 100 with a quick-release water tank includes a water tank 20 and a support assembly 50. The water tank 20 includes a body 21 and a tank frame 23. The body 21 is fixed inside the mounting cavity 2311 of the tank frame 23, thus securing the body 21. Furthermore, the tank frame 23 and the support assembly 50 are detachably connected via snap-fit ​​fasteners. During assembly, the body 21 is first fixed inside the tank frame 23, and then the tank frame 23 is connected to the support assembly 50 via snap-fit ​​fasteners. This not only enables quick assembly and disassembly of the water tank, improving efficiency, but also reduces the number of screws required for tank fixation. Compared to existing technologies, which require three screws to secure the tank body 21 to the water tank frame 23 and three screws to secure the water tank frame 23 to the support assembly 50, the improved solution only requires three screws to secure the entire water tank 20 to the support assembly 50. This reduces the cost of three screws and the number of screws needed, improving assembly and disassembly efficiency while reducing manual operation time and material consumption. Furthermore, the snap-fit ​​connection structure facilitates disassembly and maintenance, and the connection reliability meets usage requirements.

[0046] Reference Figure 2 , Figure 4 as well as Figure 5 In one embodiment of this application, the water tank frame 23 has an internal mounting cavity 2311, and the tank body 21 is fixed within the mounting cavity 2311. The water tank frame 23 includes a mounting cylinder 231 and multiple mounting buckles 233. The mounting cavity 2311 is formed inside the mounting cylinder 231, and the multiple mounting buckles 233 are spaced apart on the outer side wall of the bottom end of the mounting cylinder 231. The top end of the support assembly 50 has multiple spaced fixing buckles 51, and the mounting buckles 233 are fastened to the fixing buckles 51. The height of the mounting cylinder 231 is approximately the same as the height of the tank body 21, which can achieve the purpose of wrapping and limiting the entire tank body 21, preventing the tank body 21 from shaking due to its height. By spaced apart multiple mounting buckles 233 along the outer wall surface of the mounting cylinder 231, the mounting cylinder 231 can form multiple spaced force points, improving the uniformity of force distribution.

[0047] Please refer to Figure 4 and Figure 5In one embodiment of this application, the mounting buckle 233 includes a first mounting ear 2331, a buckle body 2332, and a reinforcing rib 2333. The first mounting ear 2331 is connected to the outer wall surface of the mounting cylinder 231, and the buckle body 2332 is connected to the surface of the first mounting ear 2331 and extends toward the support assembly 50. One end of the reinforcing rib 2333 is connected to the surface of the first mounting ear 2331 opposite to the buckle body 2332, and the other end extends toward the direction opposite to the buckle body 2332. The buckle body 2332 has a limiting surface 2332a on the side facing the mounting cylinder 231, and a guide slope surface 2332b at the end of the buckle body 2332. The fastening structure between the buckle body 2332 and the fixing buckle 51 can adopt a barbed or elastic snap-fit ​​design. The reinforcing rib 2333 can be set as a triangular or trapezoidal cross-section. The reinforcing rib 2333 structure effectively improves the load-bearing capacity of the mounting buckle 233 and ensures the reliability of the connection.

[0048] Specifically, the mounting buckle 233 is fixedly connected to the outer wall of the mounting cylinder 231 via the first mounting ear 2331, and the buckle body 2332 extends to the direction of the support component 50 and forms a fastening connection with the fixing buckle 51. The setting of the reinforcing rib 2333 enhances the structural strength of the first mounting ear 2331 and prevents the first mounting ear 2331 from deforming during the fastening process.

[0049] The limiting surface 2332a is used to limit the engagement position of the buckle body 2332 and the fixing buckle 51, and the guide slope 2332b facilitates the assembly guidance of the buckle body 2332 and the fixing buckle 51. Specifically, the limiting surface 2332a is a planar structure perpendicular to the extension direction of the buckle body 2332, which is used to contact the corresponding structure of the support component 50 during the snap-fit ​​connection to achieve axial limiting.

[0050] The guide bevel 2332b is an inclined surface located at the end of the buckle body 2332, with an inclination angle of 30-60 degrees, used to guide the fixing buckle 51 to slide smoothly into the buckle body 2332. The limiting surface 2332a effectively prevents relative displacement between the mounting buckle 233 and the fixing buckle 51 in the axial direction, ensuring connection stability. The introduction of the guide bevel 2332b significantly reduces the alignment accuracy requirements during assembly, making the snap-fit ​​connection operation more convenient. This solution maintains the reliability of the original snap-fit ​​connection while solving the problem of low assembly efficiency, without requiring additional parts or changes to the main structure.

[0051] Reference Figure 5In one embodiment of this application, the water tank frame 23 further includes a plurality of second mounting ears 235. The plurality of second mounting ears 235 are connected to the bottom end of the mounting cylinder 231 and are spaced apart along the inner wall surface of the mounting cylinder 231. Each second mounting ear 235 has a first mounting hole 2351, and the tank body 21 has a fixing hole 2131a. The tank body 21 is fixed to the second mounting ear 235 by screws engaging with the first mounting hole 2351 and the fixing hole 2131a. In one technical solution of this embodiment, the second mounting ears 235 serve as a connection structure between the tank body 21 and the mounting cylinder 231. Their number can be set according to the installation strength requirements; for example, the number of second mounting ears 235 can be 3-6.

[0052] The fixing hole 2131a of the housing 21 is aligned with the first mounting hole 2351 of the second mounting ear 235, and then fixed by self-tapping screws or machine screws, thereby achieving a reliable connection between the housing 21 and the water tank frame 23.

[0053] To address this, the technical solution utilizes a second mounting ear 235 on the inner wall, transforming the connection between the tank body 21 and the water tank frame 23 from a traditional external fixation to an internal fixation. A triangular reinforcing rib 2333 can be installed at the connection between the second mounting ear 235 and the inner wall of the mounting cylinder 231. The built-in layout of the second mounting ear 235 also improves the anti-loosening performance of the connection structure, effectively maintaining connection stability under vibration conditions. Simultaneously, the symmetrically distributed mounting ears ensure even stress distribution on the tank body 21, preventing stress concentration issues caused by unilateral fixation.

[0054] Reference Figure 5 In one embodiment of this application, the first mounting ear 2331 and the second mounting ear 235 are located on the same horizontal plane. By setting the first mounting ear 2331 and the second mounting ear 235 as a coplanar structure, when the mounting cylinder 231 bears the load of the housing 21, the first mounting ear 2331 and the second mounting ear 235 can transmit stress synchronously, avoiding torque concentration caused by height difference. This improves the overall rigidity of the bottom of the mounting cylinder 231. Compared with the structure where the first mounting ear 2331 and the second mounting ear are separate, the connection strength is greater, and the mold design is relatively simple, reducing the complexity of the mold and simplifying the processing. The mounting cylinder 231, the mounting buckle 233, and the second mounting ear 235 are an integral structure, and the material is high-strength engineering plastic to improve the structural strength of the water tank frame 23.

[0055] Reference Figure 5In one embodiment of this application, the outer wall of the mounting cylinder 231 is provided with a first mounting groove 2312, which is located at the top of the inner surface of the mounting cavity 2311. The handheld coffee machine 100 with a quick-release water tank also includes a first sealing member 30, a portion of which is located in the first mounting groove 2312 and seals against the outer wall of the housing 21. And / or, the outer wall of the mounting cylinder 231 is provided with a second mounting groove 2313, which is located near the top of the water tank holder 23. The handheld coffee machine 100 with a quick-release water tank also includes a second sealing member 40, a portion of which is located in the mounting groove and seals against the inner wall of the housing 10.

[0056] Both the first mounting groove 2312 and the second mounting groove 2313 can adopt an annular groove structure, which is used to accommodate O-ring rubber sealing rings as the first sealing element 30 and the second sealing element 40, respectively, so as to restrict the axial movement of the first sealing element 30 and the second sealing element 40. The cooperation between the first mounting groove 2312 and the first sealing element 30 can prevent liquid inside the water storage tank 20 from leaking out from the top joint, while the cooperation between the second mounting groove 2313 and the second sealing element 40 can prevent external liquid from entering the housing 10.

[0057] Reference Figure 4 and Figure 5 In one embodiment of this application, the housing 21 of the handheld coffee machine 100 with a quick-release water tank includes a housing body 211 and a support 213. The housing body 211 has a water storage cavity 2111 and a water outlet at the bottom. The support 213 includes a main body 2131 connected to the housing body 211 and a plurality of support parts 2133. Each support part 2133 is connected to the outer side wall of the housing body 211. The main body 2131 is located at the bottom of the housing body 211 and is spaced apart from the housing body 211. The support body has a fixing hole 2131a.

[0058] Specifically, the water storage chamber of the container body 211 has a volume sufficient for a single coffee brewing session. The water outlet can be located at the center of the bottom of the container body 211. The main body 2131 of the support 213 has a ring-shaped structure and is made of stainless steel by stamping. The number of support parts 2133 can be three to six, and the support parts 2133 are evenly distributed around the circumference of the container body 211 to effectively distribute the force. Each support part 2133 can be fixedly connected to the outer wall of the container body 211 by welding. The fixing hole 2131a on the main body 2131 mates with the second mounting ear 235 of the water tank bracket 23.

[0059] In one embodiment of this application, the bottom surface of the tank body 211 is inclined, and the water outlet is located on the lower side of the bottom surface. The inclined bottom design of the tank body 211 allows liquid to flow naturally to the lower side under gravity, and the location of the water outlet at this position ensures complete drainage. The inclination angle can be between 5° and 15°. This solves the problem of incomplete drainage and residue caused by traditional water tanks. The combination of the inclined bottom surface and the low-positioned water outlet significantly improves drainage efficiency and prevents bacterial growth due to liquid stagnation.

[0060] Reference Figure 4 and Figure 5 In one embodiment of this application, a handheld coffee machine 100 with a quick-release water tank includes a heating element 215, which is attached to the bottom of the housing 21. The heating element 215 can be a common heating element such as an electric heating film, an electric heating tube, or a PTC heater, and is tightly attached to the bottom of the housing 21 by thermally conductive adhesive or mechanical fixation. The heating element 215 can be configured as a ring structure to evenly cover the water outlet area at the bottom of the housing 21. Furthermore, the heating element 215 can integrate a temperature sensor and be electrically connected to a control board to achieve precise temperature control. The contact surface between the bottom of the housing 21 and the heating element 215 can be anodized to enhance thermal conductivity. By directly placing the heating element 215 at the bottom of the housing 21, the water in the water tank can be heated quickly, shortening the coffee preparation time. The direct contact design between the heating element 215 and the housing 21 reduces heat loss, simplifies the structure, and improves heat conduction efficiency.

[0061] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
