Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a portable coffee machine which is anti-dumping. Background Art

[0002] A coffee machine is a device used to make coffee. When used outdoors or in a good indoor environment, the coffee machine is generally used with a coffee machine stand, that is, the coffee machine is assembled on the coffee machine stand so that its extraction component is suspended in the air. You only need to place a cup under the extraction component to receive the coffee liquid.

[0003] However, when used in harsh outdoor environments, users may not carry too much equipment to avoid excessive weight, that is, they may not carry a coffee machine stand and an additional coffee cup. At this time, the coffee machine will have an outer cup at the bottom that can be used to collect the extracted coffee liquid, so the user only needs to hold the coffee machine in one hand and the outer cup in the other hand to operate it.

[0004] However, this type of self-contained outer cup body is generally placed on a table with its bottom on the table, and the top of the cup cover bulges outward, that is, it is not flat, and thus cannot be placed in an inverted position. Moreover, when the coffee machine is finished using and the previous capsule or coffee powder needs to be used again for secondary extraction, or when the extraction component needs to be cleaned and replaced with new capsules or coffee powder, since the outer cup body is detached and cannot be placed in an inverted position, it is not convenient to place or store the coffee machine at this time, whether it is a coffee machine with the extraction component removed or a coffee machine with the extraction component not removed. Even if it can be placed, it is placed at an angle, which causes the part of the coffee machine connected to the extraction component or the outer cup body to come into contact with the table and be contaminated by the outside world.

[0051] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0052] Example 1:

[0053] like Figures 1-11 As shown, the anti-tipping portable coffee machine includes a cup body 1, and a cup cover 2 and an outer cup body 3 are respectively provided at both ends of the cup body 1. Generally, the portable coffee machine can be placed on the outer cup body 3, but in some cases, the portable coffee machine cannot be placed on the outer cup body 3. To address this, the cup cover 2 in the utility model is provided with at least one support area on the side away from the cup body 1, and the support area can be in contact with the placement surface, thereby placing the cup body 1 vertically and preventing the cup body from tilting.

[0054] Therefore, during actual use, the cup lid 2 is provided with at least one support area on the side away from the cup body 1, and the support area can be aligned with the placement surface to place the cup body 1 vertically and prevent the cup body 1 from tilting, so that it can be inverted. Therefore, in addition to relying on the outer cup body 3 to place the entire portable coffee machine, it can also rely on the support area to place it. Moreover, when the outer cup body 3 and / or the extraction chamber 5 are removed from the cup body, the support area can also be aligned with the placement surface to prevent the cup body 1 from tilting, thereby preventing the part of the coffee machine connected to the extraction component or the outer cup body from contacting the table surface.

[0055] The placement surface is the surface on which the coffee machine is placed, such as a desktop, and the support area is the bottom surface of the cup cover 2, which is a flat surface.

[0056] Alternatively, the cup lid 2 has a groove 236 on the side away from the cup body 1, and the supporting area is a circular ring with a flat surface. Furthermore, a vent hole 26 is provided in the groove 236 to facilitate ventilation. This is because when the cup lid 2 is inverted, the side away from the cup body 1 is completely in contact with the table surface, making ventilation difficult. Therefore, the groove 236 facilitates ventilation. Of course, the groove 236 may be omitted, or the vent hole 26 may be provided.

[0057] Secondly, the cup body 1 is mounted on one end of the cup lid 2 and is provided with a third silicone member 28. The outer cup body 3 is mounted on the other end of the cup body 1 and is provided with a fourth silicone member 41. Furthermore, a silicone sleeve 25 can be provided on the outside of the cup lid 2 to prevent slipping. Specifically, the cup lid 2 includes an outer shell 23 and an inner shell 22 mounted on the outer shell 23. The cup body 1 is mounted on the outside of the inner shell 22 with a third silicone member 3 disposed between the two. Meanwhile, the cup body 1 is provided with a connector 4 at the other end, and the outer cup body 3 is mounted on the outside of the connector 4 with a fourth silicone member 41 disposed between the two.

[0058] Example 2: This example is basically the same as Example 1, except that: Figures 8-11As shown, the cup cover 2 can also cooperate with the extraction chamber 5 and / or the connecting piece 4. The specific structure is: first, the cup body 1 is provided with a connecting piece 4 at the end away from the cup cover 2, and the outer cup body 3 is sleeved on the outside of the connecting piece 4, and the extraction chamber 5 is provided on the connecting piece 4.

[0059] The portion where the cup cover 2 is connected to the cup body 1 is the connecting portion 221 , and the connecting piece 4 can be sleeved on the outside of the connecting portion 221 to place the cup body 1 on the cup cover 2 .

[0060] Moreover, the cup cover 2 is provided with a second silicone member 27 on the side close to the cup body 1 , and a mounting portion 271 is provided on the top of the second silicone member 27 , and the extraction chamber 5 can be sleeved on the outside of the mounting portion 271 to place the extraction chamber 5 on the cup cover 2 .

[0061] Therefore, in actual use, when the outer cup body 3 is removed, the extraction chamber 5 can be matched with the cup cover 2 so that the cup body 1 is placed upright on the cup cover 2, and when the outer cup body 3 and the extraction chamber 5 are removed, the connecting piece 4 can be matched with the cup cover 2 so that the cup body 1 is placed upright on the cup cover 2. At this time, since the support area can fit with the placement surface, the cup body 1 can be placed vertically, so there is no need to tilt it and the situation where the part connected to the coffee machine and the extraction component or the outer cup body contacts the desktop is avoided.

[0062] like Figure 9 As shown, the structure between the connecting member 4 and the cup cover 2 is as follows: first, a storage groove 42 is opened at the bottom of the connecting member 4, and the inner wall of the storage groove 42 is connected to the extraction chamber 5, and the opening of the storage groove 42 is sleeved on the outside of the connecting portion 221.

[0063] At the same time, the inner shell 22 of the cup cover 2 is provided with a connecting portion 221, and a mounting groove 222 is opened on the outside of the connecting portion 221, and a silicone member 3 28 is built into the mounting groove 222, and the outer side of the silicone member 3 28 abuts against the inner wall of the connecting member 4, that is, abuts against the inner wall of the storage groove 42, making the connection more stable.

[0064] like Figure 11 As shown, the structure between the extraction chamber 5 and the cup cover 2 is as follows: first, an annular plate 51 is provided at the bottom of the extraction chamber 5 , and the annular plate 51 is sleeved on the outside of the mounting portion 271 .

[0065] At the same time, the inner shell 22 of the cup cover 2 is provided with an assembly groove 223 on the side close to the cup body 1, and the second silicone member 27 is provided with an assembly portion 272 corresponding to the assembly groove 223, and the installation of the second silicone member 27 is achieved by adapting the assembly portion 272 and the assembly groove 223.

[0066] like Figures 8-11As shown, other details are as follows: First, the present invention also includes a spare cover. When the cup body 1 is placed on the cup cover 2, the spare cover can be placed on the top of the cup body 1 to prevent the top of the cup body 1 from contacting with the outside world and being contaminated. The spare cover has the same structure as the cup cover 2.

[0067] At the same time, the structure between the connecting member 4 and the outer cup body 3 is as follows: first, a silicone member 41 is provided on the outside of the connecting member 4, and a convex point is provided on the outside of the silicone member 41, and the convex point abuts against the inner wall of the outer cup body 3.

[0068] Moreover, the extraction chamber 5 and the connecting member 4 are connected by threads, and the connecting member 4 and the cup body 1 can be plugged or clamped.

[0069] Embodiment 3: This embodiment is basically the same as embodiment 1, except that the supporting area is different, that is, the supporting area is a protrusion 21, and the bottom surface of the protrusion 21 is a plane, and the setting of the protrusion 21 can also be used to increase friction, thereby making the placement more stable.

[0070] The types and structures of the protrusions 21 are various, and the protrusions 21 may be simply provided on the bottom of the cup cover 2 , or as shown in the fourth and fifth embodiments.

[0071] Furthermore, the protrusion 21 may exist alone or together with other supporting areas, for example, the protrusion 21 and the bottom surface of the cup cover 2 may exist together as a plane.

[0072] Embodiment 4: This embodiment is basically the same as embodiment 1, except that the supporting area is a protrusion 21, and the bottom surface of the protrusion 21 is a plane. The setting of the protrusion 21 can also be used to increase friction, thereby making the placement more stable.

[0073] The number of the protrusions 21 can be set according to the actual situation, and three can be selected. The specific structure of the protrusions 21 is as follows: Figure 4-Figure 5 As shown, the cup cover 2 includes an outer shell 23 and an inner shell 22 arranged on the outer shell 23, and the inner shell 22 is connected to the cup body 1. A silicone sleeve 25 is provided on the outer side of the outer shell 23, and a protrusion 21 is provided on the end of the silicone sleeve 25 away from the cup body 1.

[0074] Moreover, the silicone sleeve 25 can play an anti-slip role when holding the cup cover 2, and its installation structure is as follows: first, a bump 1 234 and a bump 2 235 are respectively provided on the upper and lower sides of the shell 23, and a hook part 1 251 is formed at the upper end of the silicone sleeve 25, and the hook part 1 251 is hooked on the outside of the bump 1 234; secondly, a hook part 252 is formed at the lower end of the silicone sleeve 25, and the hook part 1 251 is hooked on the outside of the bump 2 235.

[0075] Secondly, the outer shell 23 and the inner shell 22 are connected by screws, and corresponding to the setting of the outer shell 23 and the inner shell 22, the specific structure of the vent 26 is: the outer shell 23 is provided with a vent 26 on the side away from the cup body 1, so as to facilitate the discharge of gas between the outer shell 23 and the inner shell 22, and at the same time, the inner shell 22 is provided with holes corresponding to the vent 26 to facilitate ventilation inside and outside.

[0076] Example 5: This example is basically the same as Example 1, except that the support area is a protrusion 21, and the difference from Example 4 is the specific structure of the protrusion 21. Figure 6-Figure 7 As shown, the outer shell 23 is provided with an opening 231 on the side away from the cup body 1, and a silicone piece 24 is provided between the inner shell 22 and the outer shell 23, and the silicone piece 24 is provided with a protrusion 21 on the side close to the outer shell 23, and the protrusion 21 is exposed through the opening 231.

[0077] Moreover, the silicone member 24 also plays a sealing role in the connection between the inner shell 22 and the outer shell 23, and its installation structure is as follows: first, a connecting groove 232 is opened in the outer shell 23, and a convex strip 233 is set on the inner wall of the connecting groove 232, and the silicone member 24 is located in the connecting groove 232, and a card groove 241 is opened on the outer side of the silicone member 24 corresponding to the convex strip 233.

[0078] To sum up, when the cup cover 2 is provided with at least one support area on the side away from the cup body 1, the support area can fit into the placement surface so that the cup body 1 is placed vertically and prevents the cup body 1 from tilting, so that the entire coffee machine can be inverted. Of course, when the outer cup body 3 and / or the extraction chamber 5 are removed, the remaining whole can also be inverted.

[0079] When the cup cover 2 is provided with a support area, the cup cover 2 can also be matched with the extraction chamber 5 and / or the connecting piece 4, and can be placed upright in addition to being inverted. That is, when the outer cup body 3 is removed, the extraction chamber 5 can be matched with the cup cover 2 to place the cup body 1 upright on the cup cover 2. When the outer cup body 3 and the extraction chamber 5 are removed, the connecting piece 4 can be matched with the cup cover 2 to place the cup body 1 upright on the cup cover 2. At the same time, for more stable placement, a structure such as a protrusion 21 can also be provided.

[0080] The above shows and describes the basic principles and main features of the present invention as well as the advantages of the present invention. At the same time, the present invention is not limited to the above embodiments. Therefore, various changes and improvements are possible without departing from the principles and scope of the present invention. Such changes and improvements fall within the scope of the present invention.
