Description

Technical Field

[0001] This utility model applies to the technical field of portable coffee machine structures, and particularly relates to a sealing structure for a portable coffee machine housing. Background Technology

[0002] With increased outdoor activities, the demand for outdoor coffee brewing has also increased, leading to the development of portable coffee machines. Portable coffee machines typically consist of a water cup, a heating element, and a water pump. The heating element works with the water cup to heat water, which is then pressurized by the pump and output to the coffee powder container. The coffee powder is then extracted using this high-temperature, high-pressure water. During the extraction process, some coffee residue is inevitable, necessitating cleaning after each use. However, the water pump, heating element, and other components such as circuit boards and batteries are usually encapsulated in a housing. To accommodate the installation and sealing of the water flow channel and support other components, a bottom cover is installed at the bottom of the housing as a water flow guide and sealant. This bottom cover connects to the powder container, and therefore, screws are used to secure it to ensure a strong connection. Traditional sealing methods involve applying a ring of sealant between the midsole cover and the bottom of the housing. However, the sealant is prone to failure after long-term use. In addition, the complex structure between the bottom of the housing and the midsole cover makes it difficult to apply the sealant, which can easily lead to leakage. During cleaning, these defects can cause water to enter between the bottom of the housing and the midsole cover, which can pose a risk of short circuit to the internal components of the housing.

[0003] Therefore, a better and more effective sealing structure for the portable coffee machine casing is needed to address the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a portable coffee machine housing sealing structure with better sealing effect and long-term effectiveness.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a shell and a bottom cover. The bottom of the shell is provided with an annular limiting groove, and an annular flexible sealing element is assembled in the annular limiting groove. The bottom cover is provided with a top pressure stop edge that cooperates with the annular flexible sealing element. When the bottom cover is locked with the shell, the top pressure stop edge applies pressure to the annular flexible sealing element to cause it to deform.

[0006] As can be seen from the above solution, by setting an annular limiting groove at the bottom of the housing and a corresponding top pressure baffle on the bottom cover, the annular limiting groove and the top pressure baffle work together to press the annular flexible seal, causing it to deform and thus sealing the gap between the bottom cover and the housing. The use of a flexible seal with an annular structure ensures that it fills the gap between the bottom cover and the housing, preventing seal failure due to detachment or leakage, resulting in a long service life and easy assembly.

[0007] In a preferred embodiment, the annular flexible seal comprises an annular sealing ring.

[0008] In a preferred embodiment, the annular flexible seal includes a flexible filler layer filled in the annular limiting groove, the flexible filler layer being in the form of a closed ring.

[0009] A further preferred embodiment is that the annular flexible seal further includes a flexible filler layer, which fills the space between the annular sealing ring and the housing.

[0010] A further preferred embodiment is that the housing is provided with a plurality of limiting ribs that cooperate with the annular sealing ring, and the flexible filling layer fills the space between the annular sealing ring and the limiting ribs.

[0011] In a preferred embodiment, the bottom cover is fastened to the housing by a number of screws, the bottom cover is provided with screw holes that are adapted to the screws, and the bottom cover is provided with a sealing assembly that seals with the screw holes.

[0012] A further preferred embodiment is that the sealing assembly includes a first sealant layer filling the plurality of screw holes.

[0013] A further preferred embodiment is that the sealing assembly includes a sealing sheet, which is bonded to the bottom cover by a second sealing adhesive layer, the second sealing adhesive layer covering a plurality of the screw holes. Attached Figure Description

[0014] Figure 1 This is a three-dimensional structural schematic diagram of the present invention; Figure 2 This is a first exploded structural schematic diagram and cross-sectional view of the present invention; Figure 3 This is a cross-sectional view of the present invention; Figure 4 This is a cross-sectional view of the second exploded structural diagram of this utility model. Detailed Implementation

[0015] like Figures 1 to 4As shown, in this embodiment, the present invention includes a housing 1 and a bottom cover 2. The bottom of the housing 1 is provided with an annular limiting groove 3, and an annular flexible sealing element 4 is assembled in the annular limiting groove 3. The bottom cover 2 is provided with a top pressure baffle 5 that cooperates with the annular flexible sealing element 4. When the bottom cover 2 is locked with the housing 1, the top pressure baffle 5 applies pressure to the annular flexible sealing element 4 to cause it to deform.

[0016] One implementation method, such as Figure 2 and Figure 3 As shown, the annular flexible seal 4 includes an annular sealing ring. The annular sealing ring with a single structure provides a flexible sealing effect, ensuring that the annular sealing ring deforms under pressure when locked, thereby effectively preventing liquid from entering for a long time. This ensures that the circuit board inside the portable coffee machine does not get wet during use or cleaning, improving the safety and reliability of the portable coffee machine.

[0017] Furthermore, the annular flexible seal 4 also includes a flexible filling layer, which fills the space between the annular sealing ring and the housing 1. The flexible filling layer is a soft material filling layer that has been cured from a liquid state, such as silicone, rubber, thermoelastic plastic, or liquid silicone. The flexible filling layer supplements the annular sealing ring and, utilizing its own elastic properties, provides a sealing effect after deformation. In addition, the flexible filling layer acts as a limiting structure to prevent the annular sealing ring from shifting during assembly or maintenance, thereby avoiding gaps that could lead to later seal failure.

[0018] In another embodiment, the annular flexible seal 4 includes a flexible filling layer filled in the annular limiting groove 3, the flexible filling layer being in a closed annular shape. The closed, annular flexible filling layer cooperates with the top pressure flange 5 to achieve a seal using elasticity. Simultaneously, during filling, the material of the flexible filling layer bonds with the sidewall of the annular limiting groove 3, enhancing the sealing effect. The flexible filling layer is a soft material filling layer that has been liquid-cured, such as silicone, rubber, thermoelastic plastic, liquid silicone, etc., which is injected into the annular limiting groove 3 and then cooled and cured.

[0019] like Figure 2 As shown, in this embodiment, the housing 1 is provided with a plurality of limiting ribs 6 that cooperate with the annular sealing ring, and the flexible filling layer fills the space between the annular sealing ring and the limiting ribs 6. By providing the limiting ribs 6, the annular sealing ring is supported and limited, and the flexible filling layer is also provided with attachment points, thereby ensuring the synergistic sealing effect of the flexible filling layer and the annular sealing ring.

[0020] like Figure 3As shown, in this embodiment, a positioning ring is also fitted on the outer side of the bottom cover 2, and the positioning ring is in a limiting engagement with the housing 1. The positioning ring provides positioning, and simultaneously engages with the connection between the positioning ring and the housing 1 and the bottom cover 2, thereby initially preventing liquid intrusion.

[0021] In this embodiment, the bottom cover 2 is fastened to the housing 1 by a plurality of screws. The bottom cover 2 is provided with screw holes that are adapted to the plurality of screws, and a sealing assembly is provided on the bottom cover 2 to seal and cooperate with the plurality of screw holes. The sealing assembly covers the screw holes, thereby ensuring that the screw hole positions are not invaded by liquid during use, thus protecting the internal circuit structure.

[0022] In one embodiment, the sealing assembly includes a first sealant layer filled in a plurality of the screw holes. By directly filling the screw holes with the first sealant layer, a sealing effect is achieved. Since the contact area with water at the screw holes is small, water penetration is difficult, and the filling method minimizes gaps, resulting in a good sealing effect. However, the assembly method is relatively complex.

[0023] like Figure 4 As shown, in another embodiment, the sealing assembly includes a sealing sheet 7, which is bonded to the bottom cover 2 by a second sealing adhesive layer covering several screw holes. The integrated sealing sheet 7, in conjunction with the second sealing adhesive layer, achieves full coverage of the screw hole area. The adhesive properties of the second sealing adhesive layer are used to bond and fix the sealing sheet 7, while simultaneously using its own adhesive effect to isolate liquid, achieving double protection. This sealing method also allows for quick and convenient assembly, improving efficiency while ensuring a good seal.

[0024] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
