Description

Technical Field

[0001] This application relates to the field of coffee machine technology, and more specifically, to a small coffee machine. Background Technology

[0002] The small coffee machines currently on the market are mainly portable coffee machines. Their structure usually has the water tank located at the top of the coffee machine body, and the coffee extraction chamber is located at the bottom of the coffee machine body. Because they are designed for portability and need to be small in size, the existing technical solutions usually do not have a heating function, or can only achieve a low-power heat preservation function. In actual use, hot water often needs to be added, or cold water can be used directly for extraction. If the extraction temperature is too low, it will affect the coffee extraction effect.

[0003] Furthermore, due to the limited space in existing small coffee machines, there is insufficient space to install large water pumps, so only low-pressure water pumps can be used, which cannot extract the oils from the coffee.

[0004] At the same time, the amount of coffee extracted is small, usually less than 100ml, which cannot meet the needs of different users.

[0005] Therefore, the existing structural design of small coffee machines still has many unreasonable aspects and there is still much room for improvement.

[0006] To address the above problems, this application proposes a new solution. Utility Model Content

[0007] The purpose of this application is to provide a small coffee machine with the advantages of reasonable structural design, small space occupation and convenient use.

[0008] Firstly, this application provides a small coffee machine, the technical solution of which is as follows:

[0009] include:

[0010] The upper body has an extraction component on one side of its bottom and a first rotating component on the other side. The extraction component and the first rotating component are arranged side by side. The extraction component has a first water inlet and a first water outlet.

[0011] The lower body has a second rotating component that rotates and cooperates with the first rotating component on one side of the top of the lower body. The interior of the lower body is equipped with a water tank, a heating component and a water pump. The water tank has a second water inlet and a second water outlet, and the water pump has a third water inlet and a third water outlet.

[0012] The third water inlet is connected to the second water outlet, and the third water outlet is connected to the first water inlet. The heating component is disposed on the outside of the water tank for heating the water tank.

[0013] The coffee machine is divided into an upper body and a lower body, which are connected by the rotation of a first rotating component and a second rotating component. The extraction component is located on the upper body, side by side with the first rotating component. When brewing coffee, the upper body can be rotated to move the extraction component, which was originally stored in the lower body, to one side and is suspended in the air. At this time, a container of the same height as the lower body can be placed below the extraction component to hold the coffee extracted by the extraction component. In addition, placing the water tank in the lower body reduces the vertical space occupied by the coffee machine, making the coffee machine more stable during operation. Since the water tank is located in the lower body, it is easier to install the heating component and water pump, making the overall structure reasonable, space-saving, and easy to use.

[0014] Furthermore, in this application, the water tank is disposed on one side of the top of the lower body and located below the extraction assembly, and the second water inlet is disposed above the water tank.

[0015] Furthermore, in this application, the first rotating component and the second rotating component are nested and rotate in cooperation with each other, and the first rotating component or the second rotating component is provided with a connecting hole that connects the upper body and the lower body.

[0016] Furthermore, in this application, the water pump is located below the connection hole, and the third outlet is located on the side close to the connection hole.

[0017] Furthermore, in this application, a bushing assembly is provided between the first rotating component and the second rotating component.

[0018] Furthermore, in this application, the bushing assembly includes a first bushing and a second bushing that are nested and rotated together.

[0019] The first bushing is a vertical cylindrical structure, and the top extends horizontally with a first step. The first bushing has a first through hole that penetrates the bottom and top surfaces. The first through hole is embedded in the second rotating assembly. A first protrusion protruding from the outer surface is also provided between the first step and the outer surface of the first bushing.

[0020] The second bushing is a vertical cylindrical structure, and a second step is provided at the bottom extending horizontally. The second bushing has a second through hole that passes through the bottom and top surfaces for nesting and rotating with the first bushing. The outer circumferential surface of the second bushing is embedded in the first rotating assembly. The second step has a second protrusion protruding from the inner surface at the corresponding position of the second through hole.

[0021] The end of the first bushing away from the first step contacts the second protrusion, and the end of the second bushing away from the second step contacts the first protrusion.

[0022] Furthermore, in this application, the top of the first bushing is provided with a limiting structure protruding from the top surface, and the first rotating component is provided with a fixed locking structure. The locking structure is located above the top of the first bushing and does not exceed the limiting structure, and is used to contact the limiting structure after the upper body rotates to a specified position.

[0023] Furthermore, in this application, the outer circumferential surface of the first bushing is provided with an inwardly recessed positioning structure, and the side of the locking structure is provided with an arc portion, which is used to cooperate with the positioning structure.

[0024] Furthermore, in this application, the positioning structure is disposed on the outer surface of the first step.

[0025] Furthermore, in this application, the extraction component has a capacity of 30ml-160ml and an extraction pressure of 3bar-20bar.

[0026] As can be seen from the above, the small coffee machine provided by this application divides the main body of the coffee machine into an upper body and a lower body, and the two are rotatably connected by the rotational cooperation of a first rotating component and a second rotating component. At the same time, the extraction component is set in the upper body and arranged side by side with the first rotating component. When it is time to brew coffee, the upper body can be rotated to make the extraction component, which was originally stored in the lower body, rotate to one side and be in a suspended state. At this time, a container of the same height as the lower body can be placed below the extraction component to hold the coffee extracted by the extraction component. In addition, the water tank is set in the lower body, which reduces the vertical space occupied by the coffee machine and makes the coffee machine more stable during operation. Since the water tank is set in the lower body, it is easier to set up the heating component and water pump, making the overall structure design reasonable, space-saving and convenient to use.

Detailed Implementation

[0034] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Please refer to Figures 1 to 6 This application proposes a small coffee machine, the technical solution of which specifically includes:

[0037] The upper body 100 has an extraction component 110 on one side of its bottom and a first rotating component 120 on the other side. The extraction component 110 and the first rotating component 120 are arranged side by side. The extraction component 110 has a first inlet 111 and a first outlet 112.

[0038] The lower body 200 has a second rotating component 210 on one side of its top that rotates in conjunction with the first rotating component 120. Inside the lower body 200 are a water tank 220, a heating component 230, and a water pump 240. The water tank 220 has a second inlet 221 and a second outlet, and the water pump 240 has a third inlet 222 and a third outlet.

[0039] The third inlet 222 is connected to the second outlet, and the third outlet is connected to the first inlet 111. The heating component 230 is located on the outside of the water tank 220 for heating the water tank 220.

[0040] The extraction component 110 is a structure used to extract coffee to obtain coffee liquid. Specifically, it may include a cavity for loading coffee powder. The water pump 240 pumps water at a certain pressure from the first inlet 111 into the cavity to contact the coffee powder. Under the impact of the water, the extracted coffee liquid flows out from the first outlet 112.

[0041] The first rotating component 120 and the second rotating component 210 are rotatably connected, and can specifically adopt a nested sleeve structure.

[0042] A solenoid valve can be installed between the water tank 220 and the heating component 230, between the heating component 230 and the water pump 240, and between the water pump 240 and the extraction component 110. The solenoid valves are used to control whether the pipelines are connected.

[0043] The above design divides the coffee machine into an upper body 100 and a lower body 200, which are rotatably connected by the rotation of a first rotating component 120 and a second rotating component 210. The extraction component 110 is positioned parallel to the first rotating component 120 on the upper body 100. When brewing coffee, the upper body 100 can be rotated to move the extraction component 110, which was originally housed in the lower body 200, to one side and become suspended. A container of the same height as the lower body 200 can then be placed below the extraction component 110 to hold the coffee extracted by it. Furthermore, placing the water tank 220 on the lower body 200 reduces the vertical space occupied by the coffee machine, making it more stable during operation. Because the water tank 220 is located on the lower body 200, it is easier to install the heating component 230 and the water pump 240, resulting in a rational overall design, minimal space occupation, and convenient use.

[0044] Furthermore, referring to Figure 1 and Figure 2In some embodiments, the water tank 220 is located on one side of the top of the lower body 200 and below the extraction assembly 110, and the second water inlet 221 is located above the water tank 220.

[0045] In some embodiments, the second rotating component 210 may protrude from the upper top of the lower fuselage 200.

[0046] When the upper body 100 rotates to the designated position, the bottom of the extraction component 110 is flush with or nearly flush with the top of the lower body 200.

[0047] "Basically flush" means that there is a certain gap between the bottom of the extraction component 110 and the top of the lower body 200 to prevent friction.

[0048] The water tank 220 is positioned on the top side of the lower body 200, and the second water inlet 221 is positioned above the water tank 220, which facilitates the addition of water to the water tank 220. At the same time, the water tank 220 is positioned corresponding to the extraction component 110. When the coffee machine is not in use, the upper body 100 can be rotated to align the extraction component 110 and the water tank 220. At this time, the water tank 220 is located directly below the extraction component 110, and the extraction component 110 and the water tank 220 cover and shield each other. This serves two purposes: firstly, it prevents dust from entering the water tank 220 and the extraction component 110; secondly, it reduces space occupation, prevents the extraction component 110 from being exposed in a cantilevered manner, and also reduces the risk of bumps and provides safety protection.

[0049] Furthermore, in some embodiments, the first rotating component 120 and the second rotating component 210 are nested and rotated together, and the first rotating component 120 or the second rotating component 210 is provided with a connecting hole that connects the upper body 100 and the lower body 200.

[0050] The first rotating component 120 and the second rotating component 210 are arranged to be nested and rotated together to achieve a rotational connection between the upper body 100 and the lower body 200. At the same time, a connection hole connecting the upper body 100 and the lower body 200 can be opened on the first rotating component 120 or the second rotating component 210. By setting the connection hole, the water pump 240 of the lower body 200 and the extraction component 110 can be connected by a pipe. That is, the pipe passes through the connection hole and connects the water pump 240 and the extraction component 110. At the same time, the wires of some electrical appliances in the upper body 100 can also be introduced to the power supply of the lower body 200 through the connection hole. That is, the connection hole can serve as a place for pipes and wires, thus having the advantage of high safety.

[0051] Furthermore, in some embodiments, the water pump 240 is disposed below the connection hole, and the third outlet is disposed on the side near the connection hole.

[0052] Placing the water pump 240 below the connection hole facilitates communication between the water pump 240 and the extraction component 110. Placing the third outlet on the side close to the connection hole facilitates communication between the third outlet and the first inlet 111.

[0053] Furthermore, referring to Figure 3 and Figure 4 In some embodiments, a bushing assembly 300 is provided between the first rotating assembly 120 and the second rotating assembly 210.

[0054] The bushing assembly 300 provided between the first rotating assembly 120 and the second rotating assembly 210 can avoid wear caused by friction between the first rotating assembly 120 and the second rotating assembly 210. That is, the bushing assembly 300 can be easily disassembled and replaced, so the maintenance cost is low in the later stage.

[0055] Furthermore, in some embodiments, the bushing assembly 300 includes a first bushing 310 and a second bushing 320 that are nested and rotatably engaged with each other;

[0056] The first bushing 310 is a vertical cylindrical structure, and the top extends horizontally with a first step 330. The first bushing 310 has a first through hole that penetrates the bottom and top surfaces. The first through hole is embedded in the second rotating component 210. A first protrusion 340 protruding from the outer surface is also provided between the first step 330 and the outer surface of the first bushing 310.

[0057] The second bushing 320 is a vertical cylindrical structure, and the bottom extends horizontally with a second step 350. The second bushing 320 has a second through hole that passes through the bottom and top surfaces for nesting and rotating with the first bushing 310. The outer circumferential surface of the second bushing 320 is embedded in the first rotating assembly 120. The second step 350 has a second protrusion 360 protruding from the inner surface at the corresponding position of the second through hole.

[0058] The end of the first bushing 310 away from the first step 330 contacts the second protrusion 360, and the end of the second bushing 320 away from the second step 350 contacts the first protrusion 340.

[0059] With the above arrangement, the end of the first bushing 310 away from the first step 330 contacts the second protrusion 360, and the end of the second bushing 320 away from the second step 350 contacts the first protrusion 340. This reduces the contact area between the two, thereby reducing friction and facilitating the rotation between the upper body 100 and the lower body 200.

[0060] Furthermore, referring to Figure 5 and Figure 6In some embodiments, the top of the first bushing 310 is provided with a limiting structure 370 protruding from the top surface, and the first rotating assembly 120 is provided with a fixed locking structure 130. The locking structure 130 is located above the top of the first bushing 310 and does not exceed the limiting structure 370, and is used to contact the limiting structure 370 after the upper body 100 rotates to the designated position.

[0061] Specifically, the outer circumferential surface of the first bushing 310 is provided with an inwardly recessed positioning structure 380.

[0062] Specifically, the positioning structure 380 is disposed on the outer surface of the first step 330.

[0063] Specifically, the side of the locking structure 130 is provided with an arc portion, which is used to cooperate with the positioning structure 380.

[0064] By setting the locking structure 130 and the positioning structure 380, the rotation of the upper body 100 can be limited. On the one hand, this ensures that the upper body 100 will not shake during coffee extraction, thereby improving the stability of the extraction process. On the other hand, it can also prevent the upper body 100 from rotating excessively and causing damage to the circuit pipes, thereby improving safety.

[0065] Furthermore, in some embodiments, the extraction component 110 has a capacity of 30ml-160ml and an extraction pressure of 3bar-20bar.

[0066] The solution of this application sets the upper body 100 and the lower body 200 to be rotatably connected, with the extraction component 110 located on the upper body 100 and the water tank 220 located on the lower body 200. In actual use, the upper body 100 is rotated, causing the extraction component 110 to be in a cantilever state. Therefore, when using a cup to receive the extracted coffee, the height of the cup can be the same as that of the lower body 200, and its receiving capacity can reach 30ml-160ml, far exceeding that of ordinary portable small coffee machines. Therefore, by adopting the solution of this application, the capacity of the extraction component 110 can be set to 30ml-160ml, and the extraction pressure to be 3bar-20bar, thereby meeting the different needs of espresso and Americano.

[0067] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
