Description

Technical Field

[0001] The invention relates to the field of coffee brewing utensils, in particular to a siphon drip pot. Background Art

[0002] The siphon coffee maker is one of the most popular coffee brewing appliances in the market. It uses the steam generated by heated water to create pressure, pushes the hot water in the lower sphere to the upper pot body, and then sucks the water in the upper pot back after the lower pot cools down. The specific structure can refer to the electric siphon coffee maker disclosed in the Chinese patent announcement number CN202015058U, which includes a funnel-shaped glass upper cup and a coffee pot body distributed upper and lower. A filter is provided in the funnel-shaped glass upper cup, and the filter is fixed in the funnel-shaped glass upper cup by a spring. This setting is used to prevent the filter structure from being lifted up by air pressure when the liquid below is pushed upward, resulting in filtration failure. An electrically controlled lower seat is provided under the coffee pot body, and the coffee pot body is heated by a temperature control module.

[0003] The above-mentioned siphon coffee maker has the following areas for improvement: 1. The upper and lower bodies are plugged in and sealed together. After brewing, the upper body must be removed to pour out the coffee. In this way, a container is needed to place the upper body to prevent the residual coffee in the upper body from seeping onto the table; 2. In the existing siphon coffee maker, when all the liquid enters the upper body from the lower body, the heating component needs to be removed. The negative pressure formed by the rapid cooling of the lower body sucks the liquid in the upper body back into the lower body, thereby completing the coffee brewing process. The upper and lower bodies of the existing siphon coffee maker are both made of fast heat-conducting materials, which can quickly heat up and cool down, but cannot keep the coffee warm. This results in a short coffee extraction time and poor heat preservation performance, and the coffee needs to be drunk immediately after brewing. Summary of the Invention

[0004] The present invention addresses the shortcomings of existing siphon pots, such as the need to remove the upper pot before pouring coffee and the short coffee extraction time making it impossible to keep coffee warm, and provides a siphon drip pot that can keep coffee warm and directly pour coffee.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A siphon drip pot comprises a pot body, the pot body comprises an outer pot with a spout, a lap ring protruding from the inner wall of the outer pot and an extraction inner pot, an outer pot is provided with a heat-insulating layer under the lap ring, the extraction inner pot comprises an extraction liner and a funnel respectively located at the upper and lower ends of the lap ring and detachably sealed, the extraction liner is connected to the outer pot and the bottom thereof is sealed and lapped on the lap ring, there is a flow gap between the extraction liner and the inner wall of the outer pot for liquid to flow through, a filter is detachably provided in the funnel, a pot cover is detachably fixed to the upper end of the outer pot, and a filter is provided in the funnel. A spinning and lifting mechanism is provided between the hopper and the lid, which can drive the upper and lower chambers of the lap ring to be disconnected or connected. The spinning and lifting mechanism includes an elastic member provided between the funnel and the bottom of the outer pot to drive the inner extraction pot to rise to connect the upper and lower chambers of the lap ring, and a pressing mechanism detachably fixed to the lid for pressing the inner extraction pot downward to separate the upper and lower chambers of the lap ring. When the pressing mechanism is removed, the elastic member drives the inner extraction pot to rise to connect the upper and lower chambers of the lap ring, and the liquid below the lap ring can be poured out from the spout through the flow gap.

[0007] By adopting the above scheme, a new type of coffee pot is designed. Compared with the existing siphon pot, an insulation layer is provided outside the outer pot, which can significantly delay the heat loss of the outer pot and has good heat preservation performance. This is completely opposite to the existing technology. Through the setting of the spinning and jacking mechanism, when the bottom of the outer pot is heated to the point where the water in the chamber below the lap ring enters the extraction liner through the funnel, the heat dissipation of the chamber below the lap ring is very slow, resulting in most of the coffee liquid always being in the extraction liner, thereby extending the extraction time of the coffee and making the coffee taste richer. The extraction liner is located in the outer pot and forms a certain heat preservation function through the setting of the flow gap, which significantly reduces the temperature of the coffee in the extraction liner. The spinning and jacking mechanism in this scheme, when the top pressure mechanism is removed, is driven by the elastic member. The inner extraction pot rises, and the upper and lower chambers of the overlap ring are connected, thereby driving the air pressure of the inner extraction pot and the outer extraction pot to be balanced. The coffee liquid quickly passes through the filter into the chamber below the overlap ring under the action of gravity. There is no need to take out the inner extraction pot. The coffee in the chamber below the overlap ring can be driven to pour out from the spout through the flow gap by directly pouring the outer pot. This solution can also be used as a drip coffee pot. That is, after opening the pot lid, pour coffee powder on the filter and pour hot water directly into the extraction tank. The hot water in the extraction tank dissolves the coffee powder and enters the chamber below the overlap ring through the filter. When this solution is used as a siphon pot, it can keep the coffee liquid warm and directly pour hot coffee without taking out the inner extraction pot. It can also extend the extraction time and improve the taste of the coffee.

[0008] Preferably, the pressing mechanism includes a pressure cover provided on the upper end of the extraction liner, and there is a gas gap between the pressure cover and the extraction liner for gas to pass through. A pressure piece is quickly released on the pot lid and can press the pressure cover after installation.

[0009] By adopting the above solution, the setting of the air gap can timely discharge excess steam under the lap ring, avoiding safety hazards caused by excessive pressure. The function of the top pressure piece drives the extraction liner and the lap ring to maintain a sealed state, ensuring that there is only one outlet, the funnel, in the chamber below the lap ring.

[0010] Preferably, the top pressure piece includes a rotary vane, a top column protruding from one end of the rotary vane, and a limiting protrusion protruding from the outer ring wall of the top column. A first slot for inserting the top column and a second slot for inserting and rotating the top column and the limiting protrusion are respectively provided from top to bottom at the upper end of the pot lid. A through groove for the limiting protrusion to pass through is recessed in the inner wall of the first slot.

[0011] By adopting the above scheme, the rotation of the rotary vane can drive the limiting protrusion to align with or offset the slot. During installation, after the limiting protrusion is aligned with the slot and passes through, the rotary vane is rotated to make the limiting protrusion offset from the slot and then abut against the upper end of the second slot to achieve the limiting of the top pressure piece. The lower end of the top pressure piece presses the pressure cover and the extraction liner to make it seal with the overlap ring.

[0012] Preferably, an adjustment mechanism is provided on the pressing member to overcome errors to ensure that the pressing is performed on the pressure cover. The adjustment mechanism includes a threaded groove vertically penetrating the pressing member and a pressing bolt provided in the threaded groove.

[0013] When adopting the above solution, there will be errors in actual production. A pressing bolt is set, which can be raised and lowered relative to the pressing piece. After it is lowered, it can directly press on the pressure cover to overcome the problem of insufficient length of the pressing piece caused by the error.

[0014] Preferably, an embedding groove with a diameter larger than the thread groove is provided on the rotary vane, and a dustproof gasket capable of sealing the thread groove is embedded in the embedding groove.

[0015] With the above solution, the provision of the dustproof gasket can hide the top pressure bolt, increase the aesthetics, and prevent dust from falling into the thread groove.

[0016] Preferably, the outer edge of the lower end surface of the pressure cover is provided with abutment bosses at intervals in the circumferential direction for abutting against the upper end surface of the extraction liner, and air gaps are formed between the abutment bosses.

[0017] By adopting the above scheme, the pressing boss can press the extraction inner pot so that it can be sealed with the lap ring, so that the chamber below the lap ring has only one outlet of the funnel. The gap between the pressing bosses can allow gas to pass through, keeping the pressure in the extraction inner pot and the chamber below the lap ring from being overloaded, thereby improving the safety of operation.

[0018] Preferably, a guide mechanism is provided between the pressure cover and the pot cover to ensure that the pressure cover and the extraction pot rise synchronously after the pressing mechanism is removed. The guide mechanism includes a conduit extending downward on the pot cover, and the first slot and the second slot are arranged in the conduit. A guide platform is protruded at the lower end of the pressure cover, and a guide groove is recessed at the upper end of the guide platform for guiding the insertion of the conduit.

[0019] With the above solution, the setting of the guide mechanism can ensure that the pressure cover is lifted and lowered vertically, thereby preventing the pressure cover from shaking and blocking the pouring of coffee.

[0020] Preferably, an air vent hole smaller than the pressing bolt is provided on the pressure cover at a position opposite to the pressing bolt. When the pressing bolt presses the pressure cover, the air vent hole is in a closed state.

[0021] By adopting the above solution, the air vents on the gland can quickly balance the air pressure between the outer pot and the inner extraction pot after the top pressure piece is removed, thereby accelerating the extraction of coffee liquid in the inner extraction pot into the chamber below the overlap ring.

[0022] Preferably, a sealing structure is fixed outside the funnel, and the sealing structure includes a guide tooth ring with longitudinal teeth and a sealing ring extending horizontally outward from the upper end of the guide tooth ring and elastically abutting against the upper end surface of the overlap ring. The guide tooth ring and the overlap ring are plugged into each other and allow liquid to pass through the teeth. The length of the guide tooth ring is greater than or equal to the distance between the bottom of the conduit and the bottom of the guide groove when the extraction liner is sealed against the overlap ring.

[0023] By adopting the above solution, the sealing structure has multiple functions. When the sealing ring presses against the lap ring, the bottom of the extraction pot and the lap ring are sealed. At this time, the chamber below the lap ring has only one outlet, the extraction funnel; when the elastic member presses against the extraction pot, the guide tooth ring and the lap ring are plugged into and matched, on the one hand driving the extraction pot to rise vertically, and on the other hand, allowing the coffee in the chamber below the lap ring to enter the flow gap along the tooth groove and pour out from the spout.

[0024] Preferably, a limiting ring is horizontally extended inward from the opening at the upper end of the outer pot, a through groove is recessed on the limiting ring, an insert block is convexly provided at the lower end of the pot cover and the limiting protrusion is convexly provided on the insert block and the limiting protrusion is convexly provided on the insert block and the limiting protrusion is inserted into the through groove, and after the limiting protrusion passes through the through groove, the pot cover is rotated to abut against the lower end surface of the limiting ring.

[0025] With the above solution, the pot cover is limited by inserting the limiting protrusion into the through groove of the outer pot and rotating, so that it can be quickly fixed or removed.

[0026] Due to the adoption of the above technical scheme, the present invention has significant technical effects: compared with the existing siphon pot, the heat preservation layer is arranged outside the outer pot, which can significantly delay the heat loss of the outer pot and has good heat preservation performance, which is completely opposite to the existing technology. Through the arrangement of the spinning and jacking mechanism, when the bottom of the outer pot is heated to the point where the water in the chamber below the lap ring enters the extraction liner through the funnel, the heat dissipation of the chamber below the lap ring is very slow, resulting in most of the coffee liquid always being located in the extraction liner, thereby extending the extraction time of the coffee and making the coffee taste richer. The extraction liner is located in the outer pot and forms a certain heat preservation function through the arrangement of the flow gap, which significantly reduces the temperature of the coffee in the extraction liner. The spinning and jacking mechanism in this scheme, when the jacking mechanism is removed, Driven by the elastic component, the extraction inner pot rises, and the upper and lower chambers of the overlap ring are connected, thereby driving the air pressure of the extraction inner pot and the outer pot to be balanced. The coffee liquid quickly passes through the filter into the chamber below the overlap ring under the action of gravity. There is no need to take out the extraction inner pot. Directly pouring the outer pot can drive the coffee in the chamber below the overlap ring to pour out from the spout through the flow gap. This solution can also be used as a drip coffee pot. That is, after opening the pot lid, pour coffee powder on the filter, and directly pour hot water into the extraction inner pot. The hot water in the extraction inner pot dissolves the coffee powder and enters the chamber below the overlap ring through the filter. When this solution is used as a siphon pot, it can keep the coffee liquid warm and directly pour hot coffee without taking out the extraction inner pot. It can also extend the extraction time and improve the taste of the coffee. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] A siphon drip pot, referring to Figure 1-Figure 3 As shown, it includes a pot body, which includes an outer pot 5 with a spout 2, a lap ring 7 protruding from the inner wall of the outer pot 5, and an extraction inner pot. The outer pot 5 is provided with an insulation layer 6 below the lap ring 7. The insulation layer 6 can be made of heat-insulating silica gel. The extraction inner pot includes an extraction liner 8 and a funnel 9. The extraction liner 8 is located above the lap ring 7, and the funnel 9 is located below the lap ring 7. An insert ring 801 for inserting the funnel 9 extends from the lower end of the extraction liner 8. The insert ring 801 is threadedly connected to the funnel 9. A sealing structure 10 is fixed outside the funnel 9. The sealing structure 10 is threadedly connected to the outer ring wall of the funnel 9. The sealing structure 10 includes a guide tooth ring 1002 with longitudinal grooves on the outer ring wall. The guide tooth ring 1002 is plugged into the lap ring 7. A sealing ring 1001 is horizontally extended outward from the upper end of the guide tooth ring 1002 and can elastically abut against the upper end surface of the lap ring 7. There is a flow gap between the extraction liner 8 and the inner wall of the outer pot 5 for liquid to flow through. When the sealing ring 1001 abuts against the lap ring 7, the chamber below the lap ring 7 has only one outlet, the funnel 9; when the sealing ring 1001 rises to match the gap with the lap ring 7, the chamber below the lap ring 7 can be connected to the flow gap through the grooves.

[0039] The funnel 9 is provided with a detachable filter, combined with Figure 2 As shown, the filter is a filter disc 13, and the insert ring 801 abuts against the upper end surface of the filter disc 13. When the filter disc 13 is pushed upward, the insert ring 801 can limit the rise of the filter disc 13. A pot cover 1 is detachably fixed to the upper end of the outer pot 5. The pot cover 1 is quickly detached and arranged on the outer pot 5. Figure 4 and Figure 6As shown, a limiting ring 501 is horizontally extended inward from the upper opening of the outer pot 5, and at least one through groove 502 is circumferentially recessed on the limiting ring 501. When there is only one through groove 502, the through groove 502 is symmetrically arranged with the spout 2. An insert 101 is protruding from the lower end of the pot cover 1 and can be inserted into the limiting ring 501. At least two limiting protrusions 102 are circumferentially evenly spaced on the outer ring wall of the insert 101. After the limiting protrusion 102 passes through the through groove 502, it abuts against the lower end surface of the limiting ring 501 through the rotation of the pot cover 1. A water filter trough 103 is provided on the insert 101 to facilitate the passage of water.

[0040] A spinning jacking mechanism is provided between the funnel 9 and the pot cover 1, which can drive the upper and lower chambers of the lap ring 7 to be disconnected or connected. Figure 2 、 Figure 4 and Figure 5 As shown, the spinning jacking mechanism includes an elastic member 14 arranged between the funnel 9 and the bottom of the outer pot 5 to drive the extraction inner pot to rise to the upper and lower chambers of the overlap ring 7 and a detachable and fixed to the pot cover 1 for pressing the extraction inner pot downward to separate the upper and lower chambers of the overlap ring 7. The elastic member 14 can be arranged in the pipe section below the funnel 9 or sleeved outside the pipe section below the funnel 9. In this embodiment, it is arranged in the pipe section below the funnel 9, and a retaining ring is arranged in the pipe section below the funnel 9. The elastic member 14 is a conical spring with a downward tip and a lower end elastically abutting against the bottom of the outer pot 5. The jacking mechanism includes a pressure cover 11 arranged at the upper end of the extraction liner 8, combined with Figure 8 As shown, the outer edge of the lower end face of the pressure cover 11 is circumferentially spaced apart with abutting bosses 1102 that abut against the upper end face of the extraction liner 8. A gas gap is formed between the abutting bosses 1102 for the steam inside the extraction liner 8 to escape. A quick-release member 3 is provided on the pot lid 1, which can press the pressure cover 11 until the sealing ring 1001 elastically abuts against the overlap ring 7 after installation. Figure 7 As shown, the top pressure piece 3 includes a rotary piece 301, a top column 302 is protruding from the lower end of the rotary piece 301, and the outer ring wall of the top column 302 is protruding with limiting protrusions 102 at circumferential intervals. The upper end of the pot cover 1 is respectively provided with a first slot 1041 for the top column 302 to be inserted and a second slot 1042 for the top column 302 and the limiting protrusion 102 to be inserted and rotated. A groove 1043 for the limiting protrusion 102 to pass through is recessed on the inner wall of the first slot 1041. When the limiting protrusion 102 passes through the groove 1043 and the rotary piece 301 is rotated, the limiting protrusion 102 is topped on the upper end surface of the second slot 1042. When the top pressure piece 3 is fixed, the lower end of the top column 302 is topped on the pressure cover 11.

[0041] In order to overcome the production error and ensure that after the top pressure piece 3 is fixed, it can press the extraction liner 8 until the sealing ring 1001 and the lap ring 7 are sealed, an adjustment mechanism is provided on the top pressure piece 3. Figure 2-Figure 4As shown, the adjustment mechanism includes a threaded groove 304 vertically penetrating the pressing member 3 and a pressing bolt 12 arranged in the threaded groove 304. By adjusting the pressing bolt 12 downward, it can be ensured that the pressing bolt 12 presses the pressure cover 11 until the sealing ring 1001 elastically abuts against the lap ring 7. An embedding groove 305 with a diameter larger than the threaded groove 304 is provided on the rotary vane 301, and a dustproof gasket 4 that can seal the threaded groove 304 is embedded in the embedding groove 305, so as to prevent dust from falling into the threaded groove 304.

[0042] In order to ensure that after the top pressure piece 3 is removed, the pressure cover 11 does not shake when the outer pot 5 is tilted, a guide mechanism is provided between the pressure cover 11 and the pot cover 1. Figure 2 As shown, the guide mechanism includes a guide tube 104 extending downward from the pot cover 1, a first slot 1041 and a second slot 1042 are provided in the guide tube 104, a guide platform 1101 is provided at the lower end of the pressure cover 11, and a guide groove 1103 is provided at the upper end of the guide platform 1101 for guiding the insertion of the guide tube 104. When the elastic member 14 drives the inner pot to rise, the setting of the guide groove 1103 ensures that the pressure cover 11 can rise vertically along the guide tube 104, thereby preventing the pressure cover 11 from being stuck on the outer pot 5. When the extraction pot is tilted, shaking occurs. At the same time, the length of the guide tooth ring 1002 is greater than or equal to the distance between the bottom of the conduit 104 and the bottom of the guide groove 1103 when the sealing ring 1001 elastically abuts against the overlap ring 7. After this arrangement, when the elastic member 14 is reset, the guide tooth ring 1002 is always in a plug-in fit state with the overlap ring 7, ensuring that the extraction inner pot is always in a vertical lifting motion. When the outer pot 5 is tilted, the entire extraction inner pot and the pressure cover 11 are always in a concentric state with the outer pot 5.

[0043] In order to accelerate the removal of the pressing piece 3 and balance the air pressure in the extraction inner pot and the chamber below the overlapping ring 7, an air outlet 1104 smaller than the pressing bolt 12 is provided on the pressure cover 11 opposite to the pressing bolt 12. When the pressing bolt 12 presses the pressure cover 11, the air outlet 1104 is in a closed state.

[0044] This siphon drip pot can be used to make coffee in two ways. The first method is to use the principle of a siphon coffee machine to make coffee: the steps are as follows:

[0045] 1. First, pour clean water into the outer pot 5, and the water level should be lower than the lower end surface of the lap ring 7;

[0046] 2. Place the inner extraction pot into the outer pot 5;

[0047] 3. Place the coffee powder on top of the filter 13;

[0048] 4. Replace the gland 11 on the extraction liner 8;

[0050] 6. Fix the top pressure piece 3 on the pot cover 1;

[0051] 7. Adjust the top pressure bolt 12 until it is difficult to turn (this step is performed when the sealing performance is reduced);

[0052] 8. Place the outer pot 5 on the heating base to heat it;

[0053] 9. After all the water has entered the extraction tank 8, turn off the heating base (this process can be achieved by the temperature control program in the heating base, which is a prior art);

[0054] 10. When you want to drink coffee, turn the rotary vane 301 to remove the pressing piece 3;

[0055] 11. Pour the coffee directly.

[0056] The coffee is then poured out of the spout 2 through the funnel 9 and the outer pot 5. The coffee is then poured out of the spout 2 and the coffee is then poured out of the spout 2.

[0057] The second method is drip coffee, the steps are as follows:

[0058] 1. Remove the lid 1;

[0059] 2. Place filter paper on filter disc 13;

[0060] 3. Put coffee powder on the filter paper;

[0061] 4. Pour 80°C water into the extraction liner 8, cover with the pressure cover 11 and the pot lid 1 (no need to set the top pressure piece 3), and then filter the coffee powder through the filter paper and filter disc 13 to the chamber below the overlap ring 7.

[0062] 5. Pour the outer pot 5 directly so that the coffee liquid in the chamber below the overlap ring 7 enters the flow gap through the guide tooth ring 1002 and is poured out from the spout 2.

[0063] The drip coffee you make also does not need to take out the extraction pot, you can pour the coffee directly, which is convenient to operate and can also keep the coffee liquid warm.
