[0038] Handheld coffee machines allow people to conveniently enjoy coffee outdoors, while traveling, or in a car, meeting user needs. Internally, handheld coffee machines include a water tank, support components, and a control panel for operating the machine. In related technologies, the water tank comprises a body and a lid; however, leaks between the lid and the water tank are common, affecting the user experience.

[0039] To solve the above-mentioned technical problems, this utility model proposes a novel handheld coffee machine 100 with a leak-proof function.

[0040] Reference Figures 1 to 3 This application proposes a novel handheld coffee machine 100 with leak-proof function, including a housing 10 and a water tank 20 disposed inside the housing 10. The water tank 20 includes a body 21 and a lid 23. The body 21 is housed inside the housing 10 and is a water storage cavity 211 with an opening at one end. The lid 23 includes a connecting cover 231, a sealing cover 233, and a first sealing member 235. The connecting cover 231 is connected to the housing 10, and the sealing cover 233 is detachably connected to the connecting cover 231. The sealing cover 233 closes onto the opening end of the body 21, and the first sealing member 235 is connected to the sealing cover 233 to seal the opening of the body 21.

[0041] The housing 21 can be made of stainless steel or food-grade plastic, and its opening can be designed as round, square, or other geometric shapes. The connecting cover 231 can be fixedly connected to the housing 10 by means of threads, snap-fit ​​2317, or screws. The sealing cover 233 and the connecting cover 231 can be detachably connected by means of rotation snap-fit, press snap-fit, or magnetic attraction. The first sealing element 235 can be made of elastic materials such as silicone or rubber. The first sealing element 235 can be fixed to the sealing cover 233 by means of adhesion, snap-fit, or mechanical compression.

[0042] In the leak-proof handheld coffee machine 100 of this application, the lid 23 is configured to include a connecting cover 231 and a sealing cover 233. The connecting cover 231 is connected to the housing 10, and the sealing cover 233 and a first sealing element 235 seal the opening of the housing 21. The first sealing element 235 forms a reliable sealing interface between the sealing cover 233 and the opening of the housing 21, preventing liquid leakage from the housing 21 and effectively sealing the opening of the housing 21. This avoids the problem of water leakage from the water tank during use. The fixed connection between the connecting cover 231 and the housing 10 ensures a stable and reliable connection of the lid 23. The detachable design of the sealing cover 233 and the connecting cover 231 not only facilitates disassembly and cleaning for users but also reduces processing costs compared to welding connections. The leak-proof handheld coffee machine 100 of this application has reliable sealing performance and improves the user experience.

[0043] Reference Figures 1 to 4 In one embodiment of this application, the novel handheld coffee machine 100 with leak-proof function has a bottom end and a top end that are arranged opposite to each other. The top end of the housing 10 is provided with a mounting port 11. The casing 21 is installed inside the housing 10 through the mounting port 11. The opening of the casing 21 is not lower than the horizontal plane where the mounting port 11 is located.

[0044] The outer wall of the housing 10 near the mounting port 11 is provided with a step 13; the bottom end of the connecting cover 231 abuts against the step 13, the top end of the connecting cover 231 is set higher than the mounting port 11, and the inner wall surface of the connecting cover 231 is also provided with a mounting platform 2312; the sealing cover 233 is located on the top of the mounting platform 2312, and the sealing cover 233 is also provided with a mounting part 2331 protruding towards the water tank side, and the first sealing member 235 is fixedly connected to the sealing cover 233 through the mounting part 2331 and abuts against the mounting platform 2312 and the opening end of the water tank.

[0045] In one embodiment of this application, the mounting port 11 is used to install the housing 21 into the casing 10. The opening of the housing 21 is not lower than the horizontal plane where the mounting port 11 is located; that is, the mounting port 11 can be on the same plane as the opening of the housing 21, or the opening of the housing 21 can be set higher than the mounting port 11. If liquid overflows from the housing 21, it can be located on or above the surface of the mounting port 11 to prevent the overflowing liquid from flowing into the casing 10 and damaging other components. The step 13 on the outer wall of the casing 10 is used to limit the installation position of the connecting cover 231 and ensure the fitting accuracy between the connecting cover 231 and the casing 10. The mounting platform 2312 is used to support the sealing cover 233 and seal against the first sealing member 235 to ensure that the first sealing member 235 can form a reliable sealing interface.

[0046] Reference Figure 3In one embodiment of this application, the inner diameter of the mounting opening 11 may be slightly larger than the outer diameter of the housing 21 to facilitate the installation of the housing 21. The mounting platform 2312 is an annular boss 2333 to increase the contact area with the sealing cover 233. The mounting part 2331 may be configured as an annular protrusion to facilitate the fixing of the first sealing member 235. The mounting platform 2312 provides support for the sealing cover 233, facilitating the connection between the sealing cover 233 and the connecting cover 231. The mounting platform 2312 also abuts against the first sealing member 235 to limit excessive outward deformation of the first sealing member 235 when it is pressed against the mounting opening 11 by the sealing cover 233, which would affect the reliability of the seal. The mounting platform 2312 ensures that the sealing member can effectively perform a reliable sealing function, improves waterproof performance, avoids water leakage, and ensures the reliability and user experience of the new handheld coffee machine 100 with leak-proof function.

[0047] Reference Figure 3 In one embodiment of this application, the opening of the housing 21 and the mounting port 11 are located on the same horizontal plane, and the minimum inner diameter of the mounting platform 2312 is larger than the inner diameter of the mounting port 11. The first sealing member 235 makes sealing contact with the mounting platform 2312, the housing 10, and the water tank respectively. In the technical solution of one embodiment of this application, the fact that the opening of the housing 21 and the mounting port 11 are located on the same horizontal plane ensures that no height adjustment is required during assembly, facilitating quick positioning. The design that the minimum inner diameter of the mounting platform 2312 is larger than the inner diameter of the mounting port 11 allows the mounting platform 2312 to completely cover the edge of the mounting port 11, forming an effective support surface. The first sealing member 235 simultaneously forms sealing contact with the surface of the mounting platform 2312, the end face of the housing 10, and the opening end of the water tank, forming a reliable sealing interface.

[0048] Reference Figure 3 and Figure 7 In one embodiment of this application, the first sealing element 235 includes a fixing part 2351, a first sealing part 2354, and a second sealing part 2355. The fixing part 2351 is sleeved on the surface of the mounting part 2331. The first sealing part 2354 is connected to the top end of the fixing part 2351 and abuts against the mounting platform 2312. The second sealing part 2355 is connected to the bottom end of the fixing part 2351 and is located on the opening side of the water storage cavity 211. The inner diameter of the fixing part 2351 is slightly smaller than the outer diameter of the mounting part 2331, and fixing is achieved through an interference fit. The first sealing part 2354 can be designed as an annular flange structure, with its outer diameter larger than the inner diameter of the mounting platform 2312, achieving sealing through compression deformation. The second sealing part 2355 can be designed as a plane, with its outer diameter matching the inner diameter of the opening end of the water storage cavity 211, achieving sealing through elastic deformation.

[0049] In one embodiment of this application, the fixing part 2351 and the mounting part 2331 can be connected by a snap-fit ​​2317. A boss 2333 can be provided at the bottom of the mounting part 2331, and a fixing groove 2353 is provided at the bottom of the inner wall of the fixing part 2351. The boss 2333 is inserted into the fixing groove 2353 to limit axial displacement. Multiple annular sealing ribs can be provided on the contact surface between the first sealing part 2354 and the mounting platform 2312 to enhance the sealing effect. Through the coordinated action of the fixing part 2351, the first sealing part 2354, and the second sealing part 2355, the opening of the water storage tank 20 is covered and sealed. The fixing part 2351 ensures reliable overall positioning of the sealing element, the first sealing part 2354 prevents water vapor from leaking from the top, and the second sealing part 2355 prevents large fluctuations in the liquid within the water storage cavity 211. The technical solution of this embodiment significantly improves sealing reliability and solves the problem of easy leakage at the connection between the cover and the water tank in the prior art. (Refer to...) Figure 3 and Figure 7 In one embodiment of this application, at least one ring of sealing ribs 2352 protrudes from the side wall of the fixing part 2351, and the sealing ribs 2352 abut against the inner wall of the water storage cavity 211. The sealing ribs 2352 are annular protrusions and are continuously distributed along the circumference of the fixing part 2351. The cross-sectional shape of the sealing ribs 2352 can be semi-circular, trapezoidal, or triangular, with a height of 0.5-2 mm and a width of 1-3 mm. The sealing ribs 2352 and the inner wall of the water storage cavity 211 form an interference fit with an interference amount of 0.1-0.5 mm.

[0050] Optionally, the sealing ribs 2352 are configured as multiple rings spaced apart, with a spacing of 3-8 mm between adjacent rings. By adding the sealing ribs 2352, the reliability of the seal is further improved. In one embodiment of this application, the sealing ribs 2352 form multiple sealing contact surfaces with the inner wall of the water storage cavity 211, maintaining a stable seal even when the water tank is subjected to vibration or tilting. Compared to a single planar sealing structure, this design significantly improves sealing reliability while reducing assembly precision requirements. The elastic deformation characteristics of the sealing ribs 2352 can compensate for manufacturing tolerances and extend the service life of the seal.

[0051] Reference Figure 5 and Figure 6In one embodiment of this application, the bottom end of the mounting portion 2331 is provided with a boss 2333, and the bottom end of the inner wall surface of the fixing portion 2351 is provided with a fixing groove 2353. The boss 2333 is engaged in the fixing groove 2353 to prevent the fixing portion 2351 from separating from the mounting portion 2331. The boss 2333 is an annular protrusion extending outward from the bottom end of the mounting portion 2331, and the fixing groove 2353 is an annular groove structure recessed inward from the inner wall surface of the fixing portion 2351. The cross-sectional shape of the boss 2333 and the fixing groove 2353 can be rectangular, trapezoidal, or arc-shaped. The boss 2333 and the fixing groove 2353 adopt an interference fit, and the engagement is achieved through elastic deformation. Furthermore, the depth of the fixing groove 2353 is greater than the height of the boss 2333 to ensure that there is a margin after engagement to avoid stress concentration. The snap-fit ​​structure between the boss 2333 and the fixing groove 2353 effectively solves the problem of sealing failure caused by the easy separation of the seal and the mounting part 2331. When the seal is subjected to internal pressure in the water tank, the side wall of the fixing groove 2353 mechanically limits the boss 2333, preventing axial displacement. During assembly, positioning can be quickly completed by axial pressing without the need for auxiliary tools, thus improving assembly efficiency. Since there is no relative displacement between the seal and the mounting part 2331, stable sealing performance can be maintained even after long-term use.

[0052] In one embodiment, the sealing cover 233 is further provided with a vent hole 2334, and the mounting part 2331 is provided in the notch 2332 that communicates with the vent hole 2334. Through the notch 2332 and the vent hole 2334, the air between the first seal 235 and the sealing cover 233 can be quickly discharged, thereby improving the reliability of the first seal 235.

[0053] Reference Figure 3 In one embodiment of this application, the novel handheld coffee machine 100 with leak-proof function further includes a second sealing element 30. The second sealing element 30 is fixed to the outer wall surface of the housing 21 and is disposed near the opening end of the water storage cavity 211. The second sealing element 30 also abuts against the inner wall surface of the casing 10. The second sealing element 30 can be an annular silicone pad or a rubber ring, and its inner diameter is interference-fitted with the outer wall surface of the housing 21 to achieve fixation. The cross-sectional shape of the second sealing element 30 can be rectangular, trapezoidal, or semi-circular, wherein a trapezoidal cross-section is used to enhance the sealing pressure. The second sealing element 30 can be disposed below the opening end of the housing 21. Specific installation methods include, but are not limited to, adhesive fixing and slot embedding. As a preferred embodiment, the second sealing element 30 can be provided with multiple concentric annular protrusions to form a stepped sealing structure. The second sealing element 30 can effectively prevent liquid from entering the interior of the casing 10, avoiding the impact of leakage on the circuit of the novel handheld coffee machine 100 with leak-proof function.

[0054] Reference Figures 3 to 6In one embodiment of this application, the inner wall surface of the connecting cover 231 is provided with a plurality of spaced-apart snap fasteners 2317, and the outer peripheral surface of the sealing cover 233 is provided with a plurality of spaced-apart latching positions 2335, with the snap fasteners 2317 inserted into the latching positions 2335. The snap fasteners 2317 and latching positions 2335 engage in an elastic snap-fit ​​structure. The end of the snap fastener 2317 is provided with a guide slope, and the inner side of the latching position 2335 is provided with a limiting protrusion 2333 that matches the guide slope. The snap fasteners 2317 can be L-shaped or T-shaped, and the latching positions 2335 are grooves adapted to the shape of the snap fasteners 2317. The number of snap fasteners 2317 is 3 to 6, evenly distributed along the circumferential direction of the inner wall of the connecting cover 231, and the number and position of the latching positions 2335 are the same as those of the snap fasteners 2317. Through the insertion and engagement of the snap fasteners 2317 and latching positions 2335, a detachable connection between the connecting cover 231 and the sealing cover 233 is achieved. The mounting platform 2312 of the connecting cover 231 is also equipped with a positioning ring 2313. The positioning ring 2313 has a notch 2314, which is offset from the buckle 2317. The locking position 2335 of the sealing cover 233 is engaged into the positioning ring 2313 through the notch 2314. Then, the connecting cover 231 is connected, and the buckle 2317 on the connecting cover 231 and the locking position 2335 of the sealing cover 233 are engaged. Through the multi-point insertion structure of the buckle 2317 and the locking position 2335, the connection between the sealing cover 233 and the connecting cover 231 is more stable and uniform. At the same time, this connection method can be completed without the use of auxiliary tools, improving the convenience of maintenance. Compared with the threaded connection, the buckle 2317 structure eliminates the problem of reduced sealing performance caused by thread wear, extending the service life of the product.

[0055] Reference Figure 3 and Figure 4 In one embodiment of this application, the inner wall surface of the connecting cover 231 is provided with a first thread 2311, and the outer wall surface of the housing 10 is provided with a second thread 15. The first thread 2311 and the second thread 15 engage. The first thread 2311 can be configured as a continuous spiral or a segmented thread structure, and the thread profile can adopt a triangular, trapezoidal, or rectangular cross-sectional shape. The geometric parameters of the second thread 15 match those of the first thread 2311, and both can adopt right-hand or left-hand threads with the same direction of rotation. The thread engagement structure enables a detachable and fixed connection between the connecting cover 231 and the housing 10, facilitating the separation of the cover 23 from the housing 10 to allow water to be added to the tank 21. The axial preload generated by the thread engagement effectively prevents the connecting cover 231 from loosening under vibration, and the contact pressure of the thread engagement surface forms multiple sealing lines, significantly reducing the risk of leakage at the interface of the water storage tank 20.

[0056] Reference Figure 3 and Figure 4The outer wall surface of the connecting cover 231 is provided with an anti-slip structure 2315. The anti-slip structure 2315 may include specific forms such as raised textures, anti-slip particles, or anti-slip strips. Raised textures may be horizontal, vertical, or diagonally arranged stripes, with a depth ranging from 0.5 to 2 mm. Anti-slip particles may be hemispherical protrusions evenly distributed on the outer wall surface of the connecting cover 231, with a protrusion height ranging from 0.3 to 1 mm. Anti-slip strips may be annular protrusions surrounding the outer wall surface of the connecting cover 231, with a width ranging from 2 to 5 mm. The anti-slip structure 2315 may also be formed by covering the outer wall surface of the connecting cover 231 with rubber material. The anti-slip structure 2315 increases the coefficient of friction of the outer wall surface of the connecting cover 231, allowing the user to obtain better grip when disassembling or installing the sealing cover 233. When the connecting cover 231 is threadedly connected to the housing 10, the anti-slip structure 2315 helps the user rotate the connecting cover 231 more easily. The textured design balances anti-slip performance with aesthetics, while the anti-slip particles provide a more even distribution of friction, and the anti-slip strips facilitate manufacturing. The rubber anti-slip structure of the 2315 not only offers excellent anti-slip properties but also provides a comfortable grip.
