Description

Technical Field

[0001] The utility model relates to the field of coffee cooking utensils, in particular to a siphon pot with water outlet opening and closing switch. Background Art

[0002] The siphon pot is a widely used coffee brewing device. Its principle is to use the steam generated by heating water to create pressure, push the hot water in the lower pot body to the upper pot body, and then suck the water in the upper pot body back into the lower pot body after the lower pot body cools down.

[0003] The Chinese patent with the announcement number CN218852395U discloses a siphon drip pot, including a pot body, the pot body includes an outer pot with a spout, a convex ring convexly arranged on the inner wall of the outer pot and an extraction inner pot, the outer pot is provided with a heat preservation layer under the convex ring, the extraction inner pot includes an extraction inner pot and a funnel respectively located at the upper and lower ends of the convex ring and detachably sealed and connected, the extraction inner pot is connected with the outer pot and the bottom is sealed and overlapped on the convex ring, there is a flow gap between the extraction inner pot and the inner wall of the outer pot for liquid to flow through, a filter is detachably arranged in the funnel, and a filter is detachably arranged at the upper end of the outer pot. A pot cover is fixed on the pot cover, and a spinning and lifting mechanism is arranged between the funnel and the pot cover, which can drive the upper and lower chambers of the convex ring to be disconnected or connected. The spinning and lifting mechanism includes an elastic member arranged between the funnel and the bottom of the outer pot, which drives the extraction inner pot to rise to connect the upper and lower chambers of the convex ring, and a pressing mechanism detachably fixed on the pot cover and used for pressing the extraction inner pot downward to separate the upper and lower chambers of the convex ring. When the pressing mechanism or the pot cover is removed, the elastic member drives the extraction inner pot to rise to connect the upper and lower chambers of the convex ring, and the liquid below the convex ring can be poured out from the pot spout through the flow gap.

[0004] In the above structure, it is necessary to remove the kettle lid or take out the top pressing mechanism. These two parts are taken out and placed on the table separately, which may cause the risk of getting dirty. Utility Model Content

[0005] The utility model provides a siphon pot with water outlet and opening and closing switch, which can realize coffee pouring without removing any parts.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A siphon pot with water outlet opening and closing switch comprises an outer pot with a convex ring on the inner ring wall, an extraction inner pot overlapped on the convex ring and an elastic member arranged between the extraction inner pot and the bottom of the outer pot, a pot cover is arranged on the outer pot, a pressing component is arranged on the pot cover, an assembly structure is arranged between the pot cover and the outer pot, the assembly structure comprises a matching ring extending horizontally inward at the opening of the outer pot, a slot arranged on the matching ring and an abutment member arranged on the outer ring wall of the pot cover and fitted with the lower end face of the matching ring as it rotates after being inserted into the slot, the abutment member comprises a first step and a second step connected to one end of the first step and lower than the first step, when the first step is fitted with the lower end of the matching ring, the extraction inner pot is pressed by the pressing component and is in a sealed abutment state with the convex ring; when the second step is fitted with the lower end of the matching ring, the extraction inner pot loses the top pressure of the pressing component and is in a clearance fit state with the convex ring under the action of the elastic member.

[0008] By adopting the above scheme, the existing plug block that cooperates with the slot and abuts against the lower end of the matching ring is a flat strip structure. This scheme replaces it with an abutment member with a first step and a second step. Due to the height difference between the first step and the second step, when the two are located at the lower end surface of the matching ring, there is a height difference in the distance between the pot cover and the bottom of the outer pot, that is, there is the same height difference between the pressing component on the pot cover and the bottom of the outer pot, and this height difference can change the distance between the extraction inner pot and the convex ring. Since the upper end of the first step is higher than the second step, when the first step is located at the lower end of the matching ring, the height of the extraction inner pot in the outer pot is lower than the height of the extraction inner pot when the second step is located at the lower end of the matching ring, thereby realizing the switching of the extraction inner pot and the convex ring between abutment fit or clearance fit, and after switching, the pot cover and the outer pot always remain connected. Therefore, when pouring coffee, the pot cover does not need to be removed, and there is no need to adjust the pressing component, and the operation is more convenient and hygienic.

[0009] Preferably, a limit stop bar is provided at the intersection of the first step and the second step protruding vertically upward.

[0010] By adopting the above solution, the limit stop bar can isolate the first step and the second step, preventing the second step from excessively rotating and causing the first step to accidentally rotate to the lower end of the matching ring, thereby ensuring that the water outlet opening and closing function can be switched normally.

[0011] Preferably, an end of the first step away from the second step is provided with an introduction slope for facilitating the introduction of the first step into the lower end of the matching ring.

[0012] With the above solution, due to the presence of the elastic member, when the pot cover is matched with the outer pot, especially when the first step is matched with the matching ring, a certain resistance will be encountered. Providing an introduction slope makes it easier to guide the first step into the lower end face of the matching ring.

[0013] Preferably, the upper end surface of the first step is recessed with a weight-reducing groove at one end close to the second step.

[0014] By adopting the above scheme, the setting of the weight-reducing groove does not affect the height of the pressing assembly relative to the bottom of the outer pot when the first step is located at the lower end of the matching ring, and can also reduce materials and reduce costs.

[0015] Preferably, at least two abutments are evenly spaced around the outer ring wall of the pot cover in the circumferential direction, and the number of the slots is consistent with the number of the abutments and they are arranged in one-to-one correspondence.

[0016] By adopting the above solution and setting more than two abutment members, the lid and the outer pot are more stable after being assembled, thereby driving the descent of the pressing assembly to be more stable, ensuring that the extraction inner pot can achieve a sealed abutment fit with the convex ring.

[0017] Preferably, the pressing assembly includes a pressing cover mounted on the upper end of the extraction inner pot and a threaded knob threadedly connected to the pot cover. As the threaded knob descends, the threaded knob presses the pressing cover until the extraction inner pot is sealed and abuts against the convex ring.

[0018] By adopting the above solution, the pressing cover overlaps the extraction inner pot and can fully contact the extraction inner pot. After the threaded knob is pressed on the pressing cover, the extraction inner pot can be stably pressed against the convex ring.

[0019] Preferably, a water injection structure is provided on the pressing assembly, and the water injection structure includes a water injection groove vertically penetrating the threaded knob and a water injection hole provided on the pressing cover and facing the water injection groove.

[0020] By adopting the above solution, a water injection structure is added to the pressing component, so that water can be injected into the extraction inner pot without opening the pot lid, which makes the operation more convenient.

[0021] Preferably, the water injection channel is in the shape of a trumpet with the upper end expanding outwards.

[0022] By adopting the above solution, the water injection groove is arranged in a trumpet shape, which makes it easier to inject water.

[0023] Preferably, the extraction inner pot comprises an extraction liner and a funnel respectively located at the upper and lower ends of the convex ring. The extraction liner penetrates from top to bottom and the lower end is sealed and inserted into the funnel opening. The funnel opening extends outward and overlaps the convex ring.

[0024] Preferably, the elastic member is a spring, a retaining ring is arranged in the funnel, the spring is inserted in the funnel and its two ends are elastically in contact with the retaining ring and the bottom of the outer pot respectively.

[0025] The utility model has significant technical effects due to the adoption of the above technical scheme: the scheme replaces the flat plug with an abutment member with a first step and a second step. Due to the height difference between the first step and the second step, when the two are located at the lower end surface of the matching ring, there is a height difference between the distance between the pot cover and the bottom of the outer pot, that is, there is the same height difference between the abutment component on the pot cover and the bottom of the outer pot. This height difference can change the distance between the extraction inner pot and the convex ring. Since the upper end of the first step is higher than the second step, when the first step is located at the lower end of the matching ring, the extraction The height of the inner pot in the outer pot is lower than the height of the extraction inner pot when the second step is located at the lower end of the matching ring, that is, when the first step is located at the lower end of the matching ring, the extraction inner pot is sealed and pressed against the convex ring; when the second step is located at the lower end of the matching ring, the extraction inner pot and the convex ring have a clearance fit, so that coffee can be poured out of the outer pot. Therefore, the extraction inner pot and the convex ring can be switched between abutment fit or clearance fit by rotating the pot cover, and after switching, the pot cover and the outer pot always remain connected. Therefore, when pouring coffee, there is no need to remove the pot cover or adjust the pressing component, and the operation is more convenient and hygienic. BRIEF DESCRIPTION OF THE DRAWINGS
