Description

Technical Field

[0001] The invention relates to the technical field of moka pots, in particular to a pressurized moka pot with an anti-falling lid. Background Art

[0002] A moka pot is a tool used to extract espresso. It typically has two layers: a lower pot, where water is boiled and then sprayed through a mesh filter filled with coffee powder into an upper pot.

[0003] A Chinese patent application filed by our company with the announcement number CN211911317U discloses a glass moka pot with a quick-cleaning siphon upper pot core, comprising an upper pot body and a lower pot body, wherein the upper pot body is made of glass material and the lower pot body is made of metal material, wherein: a middle pot cover is arranged between the upper pot body and the lower pot body to connect the upper pot body and the lower pot body into one; an exchange hole seat is arranged in the center of the top cover piece of the middle pot cover, a core sealing connecting sleeve is fitted on the exchange hole seat, the core sealing connecting sleeve is fitted on the bottom of the glass core for connection, and the glass core is fixed on the exchange hole seat, and when the middle pot cover and the upper pot body are connected into one, the glass core is inserted into the upper pot body from the bottom.

[0004] The above-mentioned glass core is the only way for the water in the lower pot and the coffee powder to dissolve and spray into the upper pot, that is, the water spray pipe. A cover is set above the water spray pipe and a water outlet is set below the cover to change the path of the coffee spraying. However, the above design still has the following room for improvement: 1. The water outlet pipe (glass core) does not have an intrinsic pressurization effect, resulting in a low coffee extraction rate and poor taste; 2. The lid is hingedly set on the upper pot body, which increases the difficulty of the production process and the cost compared to the general directly overlapped lid. The existing directly covered lid is easy to cause it to slide directly from the upper pot body when pouring liquid into the upper pot body, causing the lid to be dirty. Summary of the Invention

[0005] In view of the problems that the existing moka pot has poor extraction effect and high cost of the pot lid, the purpose of the present invention is to provide a pressurized moka pot with a lid that prevents it from falling off, which can significantly improve the extraction efficiency and reduce the cost.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a pressurized moka pot with a lid that prevents it from falling off, comprising an upper pot body and a lower pot body, a pot lid being provided at the upper end of the upper pot body, a water outlet pipe being provided in the upper pot body for spraying liquid from the lower pot body into the upper pot body, a pressurizing mechanism being provided at the upper end of the water outlet pipe, the pressurizing mechanism comprising an opening and closing cover with a downward opening, the opening and closing cover being partially raised to allow the liquid in the water outlet pipe to be discharged into the upper pot body and to seal the water outlet pipe after being lowered, a pressurizing linkage mechanism for providing pressure to the pressurizing mechanism being provided at the upper end of the opening and closing cover, the pressurizing linkage mechanism comprising a weight-increasing member detachably fixed to the upper end of the opening and closing cover, the weight-increasing member being coordinated with the pot lid guide and a limit block being provided at the upper end face of the pot lid at the upper end of the weight-increasing member to prevent it from falling off the pot lid.

[0007] According to the above scheme, a booster linkage mechanism is added, and the booster linkage mechanism is connected to the opening and closing cover and the pot lid in the booster mechanism at the same time, and can be raised and lowered relative to the pot lid. Therefore, the above-mentioned booster linkage mechanism brings at least two significant technical effects. The first technical effect is that the weight of the booster mechanism can be increased, which can increase the force that the coffee needs to overcome to be sprayed from the water outlet pipe to the upper pot body, thereby extending the coffee extraction time, increasing the coffee extraction temperature, and improving the coffee extraction effect, thereby obtaining a richer and more delicious espresso; the second technical effect is that since the added linkage mechanism is always in a connected relationship with the opening and closing cover during the lifting and lowering process of the opening and closing cover, and the booster linkage mechanism is always in a connected state with the pot lid, this can drive the pot lid to always be in a closed state with the upper pot, and the pot lid can only be opened when external force drives the opening and closing cover to disengage from the booster linkage mechanism. Therefore, the phenomenon of the pot lid automatically sliding off when pouring coffee can be avoided.

[0008] Furthermore, the weight-increasing part includes a mating head at the lower end connected to the opening and closing cover, and a lifting rod arranged at the upper end of the mating head, which has a diameter smaller than the mating head and is interlaced with the pot lid, and a limit block is arranged at the end of the lifting rod away from the mating head.

[0009] According to the above scheme, the setting of the weight-increasing member can not only realize the lifting and lowering of the lifting rod and thus drive the lifting and lowering of the matching head, but also prevent it from detaching from the kettle lid. As long as the weight-increasing member is always connected to the kettle lid, it can be ensured that when the opening and closing cover is fixed to the matching head, the kettle lid will not slide off the upper kettle body due to the inclination of the upper kettle body.

[0010] Furthermore, the pot cover includes an upper cover body and a lower cover body fixedly arranged up and down, the upper cover body is provided with a first through hole for the limit block to be inserted and matched, and the lower cover body is provided with a second through hole for the lifting rod to be inserted and matched.

[0011] According to the above scheme, when installing the weight-increasing part and the pot cover, the lifting rod is first inserted and matched with the lower cover body, and then the limit block is inserted and matched with the upper pot cover, and then the upper cover body and the lower cover body are fixed to achieve assembly of the two.

[0012] Furthermore, a cover bead is provided above the upper cover body, and the cover bead is fixedly connected to the limiting block.

[0013] According to the above solution, a normal pot lid is provided with a cover bead, which facilitates opening the pot lid. At the same time, the assembly relationship between the cover bead and the pot lid is omitted, thereby reducing the difficulty of setting.

[0014] Furthermore, the mating head and the opening and closing cover are detachably connected via a magnetic structure.

[0015] Furthermore, the magnetic attraction structure includes a magnet fixedly arranged at the lower end of the mating head, and the opening and closing cover is made of a metal that can be attracted by the magnet.

[0016] According to the above scheme, the magnetic structure is a scheme with low setting difficulty and low operation difficulty among many detachable structures. Through the magnetic structure, when the magnet approaches the opening and closing cover, the matching head and the opening and closing cover will be automatically adsorbed and fixed, and only a certain external force is needed to pull the cover bead to drive the magnet to separate from the opening and closing cover. At this time, the pot lid can be easily opened.

[0017] Furthermore, an elastic anti-collision mechanism is provided outside the magnet. The elastic anti-collision mechanism is an elastic sleeve that can house the magnet and is fixed on the mating head through interference fit.

[0018] According to the above solution, the provision of the elastic sleeve can not only fix the magnet and the mating head, but also provide elastic buffering force for the magnet to avoid wear caused by direct collision between the magnet and the opening and closing cover.

[0019] Furthermore, the mating head and the opening and closing cover are detachably connected via a card structure.

[0020] Furthermore, the card structure includes a card slot recessed below the mating head and a card block provided on the upper end of the opening and closing cover and engaged with the card slot.

[0021] According to the above solution, the fast connection and fixation or fast separation between the fitting head and the opening and closing cover can also be achieved through the snap-fit structure.

[0022] Furthermore, an anti-detachment mechanism is provided between the opening and closing cover and the water outlet pipe to prevent the opening and closing cover from detaching from the water outlet pipe. The anti-detachment mechanism includes a lifting ring that is sleeved on the outside of the water outlet pipe and is provided with water outlet holes passing through it up and down, and a limiting lifting ring provided above the water outlet pipe that detaches upward from a limiting ring of the water outlet pipe. The opening and closing cover is sleeved on the outside of the limiting ring and can be lifted and lowered along the limiting ring. The lifting ring is fixedly connected to the opening and closing cover.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are: a booster linkage mechanism is added, and the booster linkage mechanism is connected to the opening and closing cover and the pot lid in the booster mechanism at the same time, and can be raised and lowered relative to the pot lid. Therefore, the above-mentioned booster linkage mechanism brings at least two significant technical effects. The first technical effect is that the weight of the booster mechanism can be increased, which can increase the force that the coffee needs to overcome when it is sprayed from the water outlet pipe to the upper pot body, thereby extending the coffee extraction time, increasing the coffee extraction temperature, and improving the coffee extraction effect, thereby obtaining a richer and more delicious espresso; the second technical effect is that since the added linkage mechanism is always in a connected relationship with the opening and closing cover during the lifting and lowering process of the opening and closing cover, and the booster linkage mechanism is always in a connected state with the pot lid, this can drive the pot lid to always be in a closed state with the upper pot, and the pot lid can only be opened when an external force drives the opening and closing cover to disengage from the booster linkage mechanism. Therefore, the phenomenon of the pot lid automatically sliding off when pouring coffee can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Example 1

[0034] A pressurized moka pot with a lid that prevents it from falling off, Figure 1-Figure 3 As shown, it includes an upper pot body 1 and a lower pot body 2, a pot cover 3 is provided on the upper pot body 1, a funnel 5 for placing coffee powder is provided in the lower pot body 2, a filter 6 is provided in the funnel 5, and coffee is placed above the filter 6, and a pressure relief valve 4 is provided on the outer wall of the lower pot body 2, a base 16 is fixed to the bottom of the upper pot body 1, and a liquid hole is provided on the base 16, and a liquid discharge mechanism is provided in the upper pot body 1, the liquid discharge mechanism includes a water outlet pipe 7 that is detachably fixed above the liquid hole. In this embodiment, a clamping ring is integrally raised above the liquid hole, and the water outlet pipe is directly and sealedly clamped on the clamping ring, and a boosting mechanism is provided at the upper end of the water outlet pipe 7 to increase the difficulty of water discharge. Through the setting of the boosting mechanism, the coffee in the water outlet pipe 7 needs to be extracted for a longer time before it can accumulate enough pressure to break through the boosting mechanism and thus be sprayed into the upper pot body 1. Therefore, the extraction efficiency of the coffee can be increased and the coffee can be made richer.

[0035] Specific reference to the booster mechanism Figure 3-Figure 5 As shown, it includes an opening and closing cover 10 that is lifted and lowered on the water outlet pipe 7, and an anti-slip mechanism is provided between the opening and closing cover 10 and the water outlet pipe 7 to prevent the opening and closing cover 10 from detaching. When the opening and closing cover 10 is lowered, its upper end face blocks the water outlet pipe 7 to prevent coffee from spraying out of the water outlet pipe 7. When the opening and closing cover 10 is raised, a gap is provided between its inner ring wall and the water outlet pipe 7 for coffee to be sprayed out, and the anti-slip structure is provided as follows: it includes a lifting ring 11 that is sleeved and lifted and arranged on the outside of the water outlet pipe 7, and the lifting ring 11 is provided with water outlet holes 12 that pass through it up and down at uniform intervals around its circumference. A limiting ring 9 is provided above the water outlet pipe 7 to limit the lifting ring 11 from detaching from the water outlet pipe 7, and the opening and closing cover 10 is sleeved on the outside of the limiting ring 9 and can move up and down along the limiting ring 9. The lifting ring 11 and the opening and closing cover are sleeved on the outside of the limiting ring 9 and can move up and down along the limiting ring 9. The lid 10 is fixedly connected. In this embodiment, the lifting ring 11 is interference fit into the gap between the opening and closing lid 10 and the water outlet pipe 7 for fixation. After such arrangement, when the water outlet pipe 7 is in a normal pressure state, the opening and closing lid 10 and the lifting ring 11 are in a descending state under the action of gravity. At this time, the upper end surface of the opening and closing lid 10 seals the water outlet pipe 7, and the rise of the opening and closing lid 10 and the lifting ring 11 requires the pressure in the water outlet pipe 7 to overcome the gravity of the boosting mechanism. Once the pressure is greater than the gravity of the boosting mechanism, the opening and closing lid 10 can be driven to rise, and the coffee will gush out from the water outlet pipe 7 into the opening and closing lid 10, and finally spray downward and evenly into the upper pot body 1 along the water outlet hole 12 on the lifting ring 11. The lifting ring 11 can also prevent the opening and closing lid 10 from separating from the water outlet pipe 7 when the pressure is too high.

[0036] In order to prevent the lid 3 from slipping when pouring coffee and to increase the pressure of the pressurizing mechanism, a pressurizing linkage mechanism is provided on the upper end of the opening and closing cover 10 to provide pressure for the pressurizing mechanism. Figure 3-Figure 5 As shown, the pressurizing linkage mechanism includes a weight-increasing member 13 detachably fixed to the upper end of the opening and closing cover 10, and the weight-increasing member 13 includes a lifting rod 131 that cooperates with the guide of the pot cover 3, and a matching head 132 that is connected to the opening and closing cover 10 is arranged at the lower end of the lifting rod 131 and below the pot cover 3. A limiting block 133 is provided above the lifting rod 131 to prevent the lifting rod 131 from separating from the pot cover 3. For the convenience of setting, the pot cover 3 includes an upper cover body 301 and a lower cover body 302 that are fixedly arranged up and down. In this embodiment, the upper cover body 301 and the lower cover body 302 are fixed by riveting or crimping, and a first through hole for the limiting block 133 to be inserted and matched is provided on the upper cover body 301, and a second through hole for the lifting rod 131 to be inserted and matched is provided on the lower cover body 302, and neither the limiting block 133 nor the matching head 132 can pass through the second through hole. In this way, it is possible The weight-increasing part 13 is set on the pot lid 3, and the lifting and lowering of the opening and closing cover 10 can drive the matching head 132 to synchronously lift and lower a certain distance below the pot lid 3. In order to increase the aesthetics, a cover bead 8 is set above the upper cover body 301, and the cover bead 8 is fixedly connected to the limit block 133. The connection method of the cover bead 8 and the limit block 133 can be threaded connection or interference fit. When the threaded connection method is adopted, a threaded groove is recessed at the lower end of the cover bead 8, and the limit block 133 is designed to be matched with the threaded groove; when the interference fit is adopted, a matching hole 801 is recessed at the lower end of the cover bead 8 for the limit block 133 to be inserted through interference. The cover bead 8 is made of insulating material. In this embodiment, the cover bead 8 is made of plastic. The setting of the cover bead 8 can not only hide the limit block 133, but also reduce the setting of the connection structure between itself and the pot lid 3, killing two birds with one stone.

[0037] After the weight-increasing member 13 and the opening and closing cover 10 are detachably arranged, at least two effects are achieved. First, the arrangement of the pressurizing linkage mechanism increases the weight of the pressurizing mechanism, so the pressurizing effect is more ideal, the coffee extraction effect is increased, and a richer and more delicious coffee is obtained. Second, since the weight-increasing member 13 cannot be separated from the pot cover 3, when the weight-increasing member 13 is fixedly matched with the opening and closing cover 10, the pot cover 3 is fixed to the pot body, which can prevent the pot cover 3 from separating from the upper pot body when pouring coffee.

[0038] In this embodiment, the mating head 132 and the opening and closing cover 10 are detachably connected via a magnetic structure. Figure 3 and Figure 5As shown, it includes a magnet 14 arranged below the mating head 132. The magnet 14 is made of samarium cobalt. The opening and closing cover 10 is made of a metal that can be absorbed by the magnet 14. In this embodiment, iron is used. In order to prevent iron from oxidizing and rusting, the opening and closing cover 10 is coated with an existing anti-oxidation coating or wrapped with a high-temperature resistant insulation layer. The high-temperature resistant insulation layer is a high-temperature resistant silicone layer with a thickness of 0.5mm to 1mm. In order to facilitate the installation of the magnet 14, an elastic anti-collision mechanism is provided on the outside of the magnet 14. The elastic anti-collision mechanism is an elastic sleeve 15 that can be embedded in the magnet 14 and fixed on the mating head 132 through interference fitting. The elastic sleeve 15 is made of high-temperature resistant silicone or high-temperature resistant rubber with a thickness of mm0.5 to 2mm. The setting of the elastic anti-collision mechanism can not only fix the magnet 14 below the mating head 132, but also play an anti-collision and buffering role, avoiding wear caused by direct rigid collision between the magnet 14 and the opening and closing cover 10.

[0039] When using the pressurized moka pot of this embodiment, after heating the lower pot body 2, the clean water in the lower pot body 2 is squeezed into the bottom of the funnel 5 as the pressure increases, and enters the funnel 5 through the filter 6 to contact the coffee powder, and completely dissolves the coffee powder as the pressure further increases. As time increases, when the pressure is greater than the total weight of the above-mentioned weight-increasing member 13 and the pressurizing mechanism, the coffee liquid in the water outlet pipe 7 pushes the opening and closing cover 10 liters. As the opening and closing cover 10 rises, the matching head 132 and the lifting rod 131 are driven to rise at the same time, and the coffee flows into the opening and closing cover 10 and is evenly sprayed downward into the upper pot body 1 along the water outlet hole.

[0040] Example 2

[0041] The difference between this embodiment and embodiment 1 is that another detachable connection structure between the opening and closing cover 10 and the mating head 132 is provided. In this embodiment, the mating head 132 and the opening and closing cover 10 are detachably connected via a card structure.

[0042] Reference Figure 6 As shown, the card structure includes a card slot 17 recessed below the mating head 132 and a card block 18 protruding from the upper end of the opening and closing cover 10 and engaged with the card slot 17. In this embodiment, the card block 18 and the card slot 17 are arranged in a ring shape concentric with the water outlet pipe 7.

[0043] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
