Description

Technical Field

[0001] The utility model relates to the field of coffee making equipment, in particular to a coffee pot. Background Art

[0002] As a coffee extraction device, a coffee pot needs to fix coffee powder inside the pot body when it is used, and add hot water to the lower part of the pot body. Then, an external inflation device will fill the lower part of the pot body with high-pressure gas. The high-pressure gas squeezes the hot water to make it flow along the built-in pipe to the coffee powder, and then evenly contact the coffee powder to form coffee liquid that flows out from the upper end of the pot body. After the coffee liquid is extracted, the gas remaining in the pot body needs to be discharged. The existing design generally sets the exhaust valve port on the lower side of the handle connected to the pot body, which can be simply pushed by the hand holding the handle to discharge the gas. However, the current design of the exhaust valve port is set below the handle, so it is easy to discharge the gas to the handle during operation, and then the handle will resist and change the direction of the gas, causing the hand holding the handle to be burned.

[0031] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0032] Please refer to Figures 1 to 6 A coffee pot, comprising a pot body 1 and a handle 2, wherein an air inlet 13 is provided on one side of the pot body 1, and a handle 2 is provided on the other side, wherein a pipeline passage 21 communicating with the pot body 1 is provided inside the handle 2; an adjustment slide valve 22 is provided on the outer side of the handle 2, and the adjustment slide valve 22 is movable along the length direction of the handle 2; an air outlet 23 communicating with the pipeline passage 21 is provided on the handle 2; an air outlet gap 24 facing the outer wall of the pot body 1 is provided between the adjustment slide valve 22 and the outer wall of the handle 2; the adjustment slide valve 22 slides to open and close the air outlet 23.

[0033] From the above description, it can be seen that the beneficial effect of the utility model is that: through the cooperation of the pipeline passage 21 in the handle 2 on one side of the kettle body 1 and the adjustment slide valve 22, the high-pressure and high-temperature gas remaining inside the processed kettle body 1 can be easily discharged by pushing the adjustment slide valve 22; at the same time, by adjusting the design of the air outlet gap 24 between the slide valve 22 and the outer wall of the handle 2, the discharged high-pressure and high-temperature gas can be discharged to the outer wall of the kettle body 1, and thus the user will not be scalded during operation.

[0034] Furthermore, the handle 2 includes a holding portion 25 and a connecting portion 26, and the holding portion 25 and the connecting portion 26 are detachably connected; a mounting cavity is provided in the holding portion 25, and a gas bullet 27 is provided in the mounting cavity; the pipeline passage 21 is provided in the connecting portion 26, and a gas bullet needle 28 is provided at the end of the pipeline passage 21 opposite to the mounting cavity.

[0035] From the above description, it can be seen that through the design of the holding portion 25 and the connecting portion 26 of the handle 2, the installation cavity of the holding portion 25 is used as an air storage structure, and the gas bomb 27 can be installed as a temporary air source to avoid the inconvenience of carrying an inflatable machine in outdoor occasions; after the holding portion 25 and the connecting portion 26 are assembled, the gas bomb needle 28 on the pipeline passage 21 will pierce the gas bomb 27 to release high-pressure gas into the pipeline passage 21; in conjunction with the air inlet 13 on the kettle body 1, the kettle body 1 can be inflated by an external inflatable device or by using a built-in temporary air source, which can be switched according to the actual usage scenario.

[0036] Furthermore, the adjustment slide valve 22 includes an air intake pin 221, a return spring 223 and a movable groove 224. The movable groove 224 is connected to the outer wall of the handle 2 at the middle part of the pipeline passage 21. The air intake pin 221 is arranged in the movable groove 224. The return spring 223 is connected between the air intake pin 221 and one end of the movable groove 224. The upper end of the adjustment slide valve 22 corresponding to the air intake pin 221 is provided with a guide inclined surface 225 inclined along its sliding direction. The upper end of the air intake pin 221 is against the guide inclined surface 225, and the lower end of the air intake pin 221 moves to open and close the pipeline passage 21.

[0037] As can be seen from the above description, when it is necessary to open the pipeline passage 21, by sliding the adjustment slide valve 22 and the guide slope 225, under the action of the return spring 223, the upper end of the air intake ejector 221 is kept against the guide slope 225 and the air intake ejector 221 is gradually moved upward along the moving groove 224 while the guide slope 225 moves, so that the lower end of the air intake ejector 221 no longer blocks the pipeline passage 21; conversely, when it is necessary to block the pipeline passage 21, by sliding the adjustment slide valve 22 and the guide slope 225, the lower end of the air intake ejector 221 is gradually moved downward to block the pipeline passage 21.

[0038] When the gripping portion 25 of the handle 2 is connected to the connecting portion 26 , the gas bullet needle 28 punctures the gas bullet 27 . At this time, the air inlet ejector 221 is required to keep the pipeline passage 21 closed so that the slide valve 22 can be slid and adjusted for use when needed.

[0039] Furthermore, the adjusting slide valve 22 slides to a first position on the outer wall of the handle 2 to open the air outlet 23 and close the pipeline passage 21, and the adjusting slide valve 22 slides to a second position on the outer wall of the handle 2 to close the air outlet 23 and open the pipeline passage 21; a locking structure 226 is provided on the adjusting slide valve 22, and a first locking socket 29 and a second locking socket 210 cooperating with the locking structure 226 are respectively provided on the outer wall of the handle 2 corresponding to the first position and the second position.

[0040] It can be seen from the above description that through the design of the first bayonet 29 and the second bayonet 210 and the positioning structure 226 on the adjustment slide valve 22, the user can accurately control the adjustment slide valve 22 to slide to the sliding position of opening the air outlet 23, closing the pipeline passage 21 or closing the pipeline passage 21 and opening the air outlet 23 when using it.

[0041] Furthermore, an extraction component 14 is provided in the kettle body 1; the extraction component 14 includes a flow guide component, the flow guide component includes a water guide pipe 141, a water guide plate 142 and a flow limiting structure, the water guide pipe 141 is connected to the water guide plate 142, a flow limiting structure is provided in the water guide pipe 141, the flow limiting structure includes a flow limiting central bolt 146, a flow limiting valve core 147 and a flow limiting spring 148, the flow limiting central bolt 146 is provided in the water guide pipe 141, the flow limiting valve core 147 is movable between the upper end of the water guide pipe 141 and the flow limiting central bolt 146; a flow limiting spring 148 is connected between the flow limiting valve core 147 and the upper end of the water guide pipe 141; the lower end of the flow limiting valve core 147 abuts against the flow limiting central bolt 146 to close the water guide pipe 141.

[0042] It can be seen from the above description that the extraction component 14 arranged in the kettle body 1 extracts the coffee powder after the high-pressure gas is introduced into the kettle body 1; wherein the extraction component 14 includes a guide component for the hot water in the kettle body 1, and the hot water flows to the upper end of the kettle body 1 through the guide component; the guide component can control the flow rate and water pressure of the water passing through it through the flow limiting structure arranged in its water pipe 141, thereby ensuring the uniformity and thoroughness of the subsequent extraction process; specifically, when the high-pressure gas is filled into the kettle body 1, the hot water in the kettle body 1 is pushed into the water pipe 141 by the high-pressure gas, and the hot water passes through the middle part of the flow-limiting central bolt 146 in turn. When the hot water pressure reaches the extraction requirement, the hot water can overcome the action of the flow-limiting spring 148 and push the flow-limiting valve core 147 so that it no longer abuts against the closed flow-limiting central bolt 146, thereby opening the water pipe 141.

[0043] Furthermore, the water conduit 141 is provided with an internal thread, the flow-limiting central bolt 146 is provided with an external thread, and the flow-limiting central bolt 146 is threadably matched with the water conduit 141 .

[0044] From the above description, it can be seen that through the cooperation of the internal thread of the water pipe 141 and the external thread of the flow limiting central bolt 146, the user can adjust the position of the flow limiting central bolt 146 in the water pipe 141, and then compress or stretch the flow limiting spring 148 to adjust the flow rate and water pressure of the flow limiting water.

[0045] Furthermore, it also includes a liquid outlet 3, a liquid outlet groove 111 is provided at the upper end of the kettle body 1, a liquid outlet 112 is provided in the liquid outlet groove 111, the liquid outlet 3 is arranged at the liquid outlet 112, the inlet of the liquid outlet 3 is connected with the liquid outlet 112, and the outlet of the liquid outlet 3 is higher than the liquid outlet 112.

[0046] It can be seen from the above description that after the coffee is extracted, it flows into the liquid outlet 112 and gathers in the liquid outlet groove 111 at the upper end of the pot body 1; by setting the liquid outlet 3, its outlet is higher than the liquid outlet 112, so that the extracted coffee will flow out along the liquid outlet 3 and fall into the liquid outlet groove 111, which can effectively prevent the coffee liquid from flowing back after extraction; at the same time, the height of the liquid outlet 3 can be used as a measurement reference to determine the extraction amount of a single coffee liquid.

[0047] Furthermore, it also includes a barometer 4, and the positions on both sides of the kettle body 1 corresponding to the handle 2 are respectively provided with a first joint 121 and a second joint 122, and the first joint 121 and the second joint 122 are both connected to the inside of the kettle body 1; the first joint 121 and the second joint 122 are selectively connected to the barometer 4.

[0048] As can be seen from the above description, the pressure of the high-pressure gas filled in the kettle body 1 can be observed through the barometer 4, and a certain pressure requirement is required when extracting coffee. The first joint 121 and the second joint 122 on the kettle body 1 are designed to be located on both sides of the handle 2, and can be adjusted according to the user's dominant hand to facilitate observation.

[0049] Furthermore, the lower end surface of the kettle body 1 is provided with anti-slip lines 123 ; the lower end edge of the kettle body 1 is provided with a circle of inclined heat-conducting surface 124 , and the heat-conducting surface 124 is provided with heat-conducting lines 125 .

[0050] From the above description, it can be seen that the design of the anti-slip texture 123 on the lower end surface of the kettle body 1 can prevent the kettle body 1 from slipping due to accidental touching after being placed, thereby affecting the operation; in addition, the inclined heat-conducting surface 124 designed on the lower edge of the kettle body 1 can enable the kettle body 1 to match the shape of the upper end of the flame being blocked by an object and inclined and diverging when the pressure and water temperature in the kettle body 1 are increased by direct flame heating, so that the kettle body 1 can fully contact the flame and heat up quickly; and the design of the anti-slip texture 123 and the heat-conducting texture 125 can further increase the heated area and improve the heating efficiency.

[0051] Furthermore, a heat dissipation fin 113 and a heat-insulating anti-slip ring 114 are provided on the upper portion of the kettle body 1 .

[0052] From the above description, it can be seen that the heat dissipation fins 113 on the upper part of the kettle body 1 can be used to quickly dissipate heat and cool down after coffee is extracted; and the design of the heat-insulating anti-slip ring 114 prevents the user from being scalded by overheating of the kettle body 1 when holding the kettle body 1 when transferring or cleaning the kettle body 1, and also plays an anti-slip role.

[0053] Embodiment 1:

[0054] Application scenarios: The design of existing coffee pots generally sets the exhaust valve port on the lower side of the handle 2 connected to the pot body 1, and the gas can be discharged by simply pushing the handle 2 with the hand holding it. However, the current design of the exhaust valve port is set below the handle 2, so it is easy for the gas to be discharged to the handle 2 during operation, and then the gas is blocked by the handle 2 and the direction of the gas is changed, causing the hand holding the handle 2 to be burned.

[0055] like Figures 1 to 4 As shown, the coffee pot of this embodiment comprises a pot body 1 and a handle 2, wherein an air inlet 13 is provided on one side of the pot body 1, and a handle 2 is provided on the other side, wherein a pipeline passage 21 communicating with the pot body 1 is provided inside the handle 2; an adjustment slide valve 22 is provided on the outer side of the handle 2, and the adjustment slide valve 22 is movable along the length direction of the handle 2; an air outlet 23 communicating with the pipeline passage 21 is provided on the handle 2; an air outlet gap 24 facing the outer wall of the pot body 1 is provided between the adjustment slide valve 22 and the outer wall of the handle 2.

[0056] like Figure 2 As shown, the handle 2 includes a gripping portion 25 and a connecting portion 26, and the gripping portion 25 and the connecting portion 26 are detachably connected; specifically, the connecting portion 26 is provided with an external thread, and the gripping portion 25 is provided with an internal thread, and the two are connected by threaded matching. A mounting cavity is provided in the gripping portion 25, and a gas bullet 27 is provided in the mounting cavity; the pipeline passage 21 is provided in the connecting portion 26, and a gas bullet needle 28 is provided at the end of the pipeline passage 21 opposite to the mounting cavity. A heat-insulating silicone ring is sleeved on the end of the connecting portion 26 opposite to the gripping portion 25, and the heat-insulating silicone ring simultaneously blocks the gap between the connecting portion 26 and the gripping portion 25.

[0057] like Figure 3 and Figure 4 As shown, the adjustment slide valve 22 includes an air intake pin 221, a return spring 223 and a movable groove 224. The middle part of the pipeline passage 21 is connected to the outer wall of the handle 2 with a movable groove 224. The air intake pin 221 is arranged in the movable groove 224. The return spring 223 is connected between the air intake pin 221 and one end of the movable groove 224. The upper end of the adjustment slide valve 22 corresponding to the air intake pin 221 is provided with a guide inclined surface 225 inclined along its sliding direction. The upper end of the air intake pin 221 is against the guide inclined surface 225, and the lower end of the air intake pin 221 moves to open and close the pipeline passage 21.

[0058] like Figure 4As shown, the first sealing ring 227 and the second sealing ring 228 are respectively provided at the two ends of the length direction of the corresponding guide inclined surface 225 on the adjusting slide valve 22; the third sealing ring 222 for blocking the air outlet 23 is provided on the adjusting slide valve 22 corresponding to the air outlet 23. A heat-insulating silicone ring is provided on the outer side of the corresponding adjusting slide valve 22, and the gripping part 25 is designed as a wooden structure, so as to prevent the kettle body 1 from transferring heat to the handle 2 and making it inconvenient to hold it.

[0059] The adjustment slide valve 22 slides to the first position of the outer wall of the handle 2 to open the air outlet 23 and close the pipeline passage 21, and the adjustment slide valve 22 slides to the second position of the outer wall of the handle 2 to close the air outlet 23 and open the pipeline passage 21; the adjustment slide valve 22 is provided with a locking structure 226, and the outer wall of the handle 2 is respectively provided with a first locking port 29 and a second locking port 210 that match the locking structure 226 corresponding to the first position and the second position. Specifically, the locking structure 226 can be in the form of marbles, etc., which can make a certain sound when docking with the corresponding locking port to prompt the user to adjust to the right position.

[0060] Working principle: after assembling the gas bullet 27, connect the gripping portion 25 of the handle 2 with the connecting portion 26. At this time, the pipeline passage 21 is in a closed state, that is, the lower end of the air inlet ejector pin 221 blocks the pipeline passage 21. When connected, the gas bullet 27 abuts against the gas bullet needle 28 on the connecting portion 26 and is punctured, and the gas cannot flow into the kettle body 1 due to the blocking of the pipeline passage 21.

[0061] After the coffee powder and hot water required for extraction are prepared, the adjusting slide valve 22 is pushed by the hand holding the handle 2, so that under the action of the return spring 223 and the guide slope 225, the upper end of the air intake pin 221 is kept against the guide slope 225 and the air intake pin 221 is gradually moved upward along the moving groove 224 while the guide slope 225 moves, so that the lower end of the air intake pin 221 no longer closes the pipeline passage 21, and the high-pressure gas in the gas bomb 27 is filled into the kettle body 1, thereby squeezing the hot water to flow toward the coffee powder.

[0062] After the coffee liquid is extracted, the adjustment slide valve 22 can be pushed in the reverse direction so that the lower end of the air inlet ejector pin 221 closes the pipeline passage 21 and at the same time the third sealing ring 222 of the adjustment slide valve 22 no longer blocks the air outlet 23. The high-temperature gas remaining after contact with the hot water is discharged toward the outer wall of the kettle body 1 from the air outlet gap 24 between the adjustment slide valve 22 and the connecting portion 26 of the handle 2. The gas is dispersed along the outer wall of the kettle body 1 and does not go toward the hands, thereby avoiding scalding.
