Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a coffee machine with a lockable funnel. Background Technology

[0002] Most low-cost home coffee machines on the market do not have a dedicated pressure relief system. If the funnel is removed while it is under pressure, the hot coffee grounds inside the funnel may suddenly burst out due to the pressure release, scalding the user.

[0003] For example, Chinese utility model publication CN220236654U discloses a coffee machine with a self-locking funnel, including a body and a funnel. The body has a placement position, and the outer wall of the placement position has at least one limiting groove. The funnel has at least one protrusion, which engages with the limiting groove. The placement position has a locking structure capable of locking and positioning the funnel. The locking structure includes an elastic element and a locking element. The placement position has an installation position, and the elastic element is disposed in the installation position. The locking element is connected to the elastic element and can extend from the installation position to engage with the side wall of the protrusion or the engaging groove on the protrusion to lock the protrusion in place. The aforementioned prior art coffee machine locks the funnel through a locking structure, but the funnel can still be removed under pressure.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a coffee machine with a lockable funnel.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides a coffee machine with a lockable funnel, including a heating assembly, a funnel support, and a funnel. The funnel support and funnel are correspondingly arranged and can be rotated and locked together. The funnel has a locking groove, and the funnel support has a locking valve with a through hole at the bottom. A sliding head is slidably arranged in the valve cavity of the locking valve, and the outer periphery of the sliding head is sealed to the side wall of the valve cavity of the locking valve. It also includes a locking rod, the first end of which is connected to the sliding head, and the second end of which passes through the through hole and corresponds to the locking groove. The locking valve has an interface communicating with the valve cavity, and the funnel support has a water inlet. The water outlet of the heating assembly is connected to the interface and the water inlet respectively.

[0008] Hot water and / or steam with a certain pressure generated by the heating element enter the funnel and valve chamber respectively. The sliding head and locking rod move downward under pressure, so that the locking rod inserts into the locking groove. This makes it impossible to remove the funnel from the funnel support when the funnel is under pressure, effectively improving the safety of use.

[0009] It is understandable that hot water and / or steam with a certain pressure generated by the heating element is delivered into the funnel through the inlet on the funnel support, so that there is pressure inside the funnel; and the outlet of the heating element is connected to the interface and the inlet respectively, so that when there is pressure inside the funnel, there is also pressure inside the valve cavity.

[0010] According to the above scheme, the funnel support is provided with a snap-fit ​​groove, the funnel is provided with a lug that rotates and locks with the snap-fit ​​groove, and the locking groove is provided on the lug.

[0011] According to the above scheme, the valve cavity is provided with an elastic element, which acts on the sliding head and the valve cavity to make the locking rod tend to move away from the locking groove.

[0012] By incorporating an elastic element, when the coffee machine finishes brewing coffee and the heating component stops working, the pressure inside the valve chamber gradually decreases. Under the elastic action of the elastic element, the locking rod automatically moves upward to reset, causing the locking rod to disengage from the locking groove. At this point, the funnel can be removed from the funnel holder.

[0013] According to the above scheme, the elastic element is a spring, the sliding head has a T-shaped structure, the spring is sleeved on the sliding head, and the two ends of the spring abut against the bottom of the sliding head and the valve cavity, respectively.

[0014] It is understood that in some embodiments, the elastic element may be configured as a structure other than a spring.

[0015] According to the above scheme, the locking valve includes a base and a seat cover, the seat cover being a detachable sealing cap disposed on the base; the interface is disposed on the seat cover, and the through hole is disposed on the base. By providing a detachable connection between the seat cover and the base, it is convenient to clean and maintain the locking valve.

[0016] According to the above scheme, the base is provided with a groove, the bottom of the seat cover is provided with a flange, the flange is provided in the groove and close to the side wall of the groove, and the outer periphery of the flange is provided with a first sealing ring that is sealed and connected to the base; the sliding head is provided in the flange, and the seat cover, the flange and the base form the valve cavity.

[0017] According to the above scheme, a second sealing ring is provided on the outer periphery of the first end of the locking rod; when the second end of the locking rod is inserted into the locking groove, the second sealing ring is sealed to the through hole. By setting the second sealing ring, liquid entering the valve cavity can be prevented from flowing out through the through hole, improving the sealing performance of the valve cavity and ensuring that the sliding head remains under pressure throughout the coffee making process.

[0018] According to the above scheme, it also includes a body, the heating component is disposed in the body, and the funnel support is disposed on the body.

[0019] According to the above scheme, the outlet of the heating component is connected to the interface and the inlet via a three-way heat-resistant pipe. The use of a three-way heat-resistant pipe improves the ease of connecting the heating component to the interface and the inlet.

[0020] According to the above design, the funnel is equipped with a handle. The handle allows the user to easily rotate and lock the funnel into the locking slot of the funnel holder.

[0021] According to the above scheme, the heating assembly includes a heating pot and a heating element, with the heating element disposed on the heating pot. The heating element transfers heat to the heating pot, thereby heating the water inside the heating pot.

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention features a locking valve on a funnel support. A sliding head is slidably and sealingly connected within the valve chamber of the locking valve. The outer periphery of the sliding head is sealed against the side wall of the valve chamber. The first end of a locking rod is fixedly connected to the sliding head, and the second end of the locking rod passes through a through-hole at the bottom of the locking valve, corresponding to a locking groove on the funnel. The outlet of the heating element is connected to the inlet on the funnel support and the interface on the locking valve. This allows hot water and / or steam with a certain pressure generated by the heating element to enter the funnel and the valve chamber respectively. Under pressure, the sliding head and locking rod move downwards, causing the locking rod to insert into the locking groove. This prevents the funnel from being removed from the funnel support when pressure is present, effectively improving safety during use. Attached Figure Description

[0031] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-6 As shown, this utility model provides a coffee machine with a lockable funnel, including a heating assembly 1, a funnel support 2, and a funnel 3. The funnel support 2 and the funnel 3 are correspondingly arranged and can be rotated and locked together. The funnel 3 is provided with a locking groove 311, and the funnel support 2 is provided with a locking valve 4. The bottom of the locking valve 4 is provided with a through hole 412. A sliding head 5 is slidably provided in the valve cavity 43 of the locking valve 4, and the outer periphery of the sliding head 5 is sealed with the side wall of the valve cavity 43 of the locking valve 4. It also includes a locking rod 6. The first end of the locking rod 6 is connected to the sliding head 5, and the second end of the locking rod 6 passes through the through hole 412 and corresponds to the locking groove 311. The locking valve 4 is provided with an interface 423 that communicates with the valve cavity 43, and the funnel support 2 is provided with a water inlet 22. The water outlet 13 of the heating assembly 1 is connected to the interface 423 and the water inlet 22 respectively.

[0033] Hot water and / or steam under pressure generated by heating component 1 is delivered into funnel 3 through inlet 22 on funnel support 2, creating pressure within funnel 3. Outlet 13 of heating component 1 is connected to interface 423 and inlet 22, ensuring pressure exists within both funnel 3 and valve chamber 43. When pressurized hot water and / or steam enter valve chamber 43, sliding head 5 and locking rod 6 move downwards under pressure, causing locking rod 6 to insert into locking groove 311. This prevents funnel 3 from being removed from funnel support 2 when pressure exists within funnel 3, effectively improving safety.

[0034] Furthermore, the funnel support 2 is provided with a snap-fit ​​groove 21, and the funnel 3 is provided with a lug 31 that rotates and locks with the snap-fit ​​groove 21, and the locking groove 311 is provided on the lug 31.

[0035] Furthermore, the valve cavity 43 is provided with an elastic element, which acts on the sliding head 5 and the valve cavity 43 to make the locking rod 6 tend to move away from the locking groove 311; the elastic element is a spring 51, the sliding head 5 has a T-shaped structure, the spring 51 is sleeved on the sliding head 5, and the two ends of the spring 51 abut against the bottom of the sliding head 5 and the valve cavity 43 respectively.

[0036] When the coffee machine finishes brewing coffee, the heating component 1 stops working, the pressure in the valve chamber 43 gradually decreases, and under the elastic action of the spring 51, the locking rod 6 automatically moves upward to reset, so that the locking rod 6 is disconnected from the locking groove 311. At this time, the funnel 3 can be removed from the funnel bracket 2.

[0037] Furthermore, the locking valve 4 includes a base 41 and a cover 42, the cover 42 being detachably sealed on the base 41; the interface 423 is located on the cover 42, and the through hole 412 is located on the base 41. By providing a detachable connection between the cover 42 and the base 41, it is convenient to clean and maintain the locking valve 4.

[0038] Furthermore, the base 41 is provided with a groove 411, and the bottom of the cover 42 is provided with a flange 421. The flange 421 is located in the groove 411 and is close to the side wall of the groove 411. The outer periphery of the flange 421 is provided with a first sealing ring 422 that is sealed to the base 41. The sliding head 5 is located in the flange 421. The cover 42, the flange 421 and the base 41 form the valve cavity 43.

[0039] Furthermore, a second sealing ring 61 is provided on the outer periphery of the first end of the locking rod 6; when the second end of the locking rod 6 is inserted into the locking groove 311, the second sealing ring 61 is sealed to the through hole 412. By providing the second sealing ring 61, liquid entering the valve cavity 43 can be prevented from flowing out through the through hole 412, improving the sealing performance of the valve cavity 43 and ensuring that the sliding head 5 remains under pressure throughout the coffee making process.

[0040] Furthermore, it also includes a body 7, the heating component 1 is disposed inside the body 7, and the funnel support 2 is disposed on the body 7.

[0041] Furthermore, the outlet 13 of the heating component 1 is connected to the interface 423 and the inlet 22 respectively via a three-way heat-resistant pipe 8. By setting the three-way heat-resistant pipe 8, the convenience of connecting the heating component 1 to the interface 423 and the inlet 22 is improved.

[0042] Furthermore, the funnel 3 is provided with a handle 32. By providing the handle 32, it is convenient for the user to rotate and lock the funnel 3 onto the snap-fit ​​groove 21 of the funnel bracket 2.

[0043] Furthermore, the heating assembly 1 includes a heating pot 11 and a heating element 12, the heating element 12 being disposed on the heating pot 11. The heating element 12 transfers heat to the heating pot 11, thereby heating the water inside the heating pot 11.

[0044] When using the coffee machine with a lockable funnel described in this utility model, coffee powder is placed into the funnel 3, and the handle 32 of the funnel 3 is held to rotate and lock the lug 31 onto the snap-fit ​​groove 21 of the funnel bracket 2. The heating element 12 is then activated to heat the water in the heating pot 11, thereby generating hot water and / or steam with a certain pressure. The hot water and / or steam are split into two paths through the three-way heat-resistant pipe 8. One path is delivered to the funnel 3 through the water inlet 22 on the funnel bracket 2 to brew the coffee powder, and the other path enters the valve chamber 43 through the interface 423 of the seat cover 42. When the hot water and / or steam enter the valve chamber 43, the sliding head 5 and the locking rod 6 move downward under pressure, causing the locking rod 6 to insert into the locking groove 311 and compress the spring 51. At this time, the funnel 3 cannot be removed from the funnel bracket 2.

[0045] When the coffee machine finishes brewing coffee, the heating component 1 stops working, the pressure in the valve chamber 43 gradually decreases, and under the elastic action of the spring 51, the locking rod 6 is driven to return to its original position, so that the locking rod 6 is disengaged from the locking groove 311. At this time, the funnel 3 can be removed from the funnel bracket 2.

[0046] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
