Description

Technical Field

[0001] This utility model relates to the field of coffee machines, specifically a chain structure for a coffee machine funnel. Background Technology

[0002] Existing pressure coffee machines on the market, including water-tank and pump-type machines, require consumers to fill the coffee grounds, assemble the funnel, and lock it onto the machine's frame before brewing. All of these machines have a structural flaw: the funnel needs to be rotated to a specific position to prevent it from detaching and causing injury. If the operator does not rotate the funnel to the designated position before brewing, the high temperature and pressure during brewing can cause the locking mechanism between the funnel and its holder to loosen and slip. This can result in the funnel slipping and detaching, causing coffee and grounds to splatter and burn the operator. Therefore, a safety mechanism is needed to improve the funnel structure of coffee machines to ensure safe operation. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned existing problems and provide a simple and reasonable interlocking structure for a coffee machine funnel.

[0004] An interlocking structure for a coffee machine funnel includes a main body, a water pressure assembly, a funnel device, and a control system.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1 to 5As shown, an interlocking structure for a coffee machine funnel includes a main body 1, a water pressure assembly, a funnel device 2, and a control system 3. The water pressure assembly and the control system 3 are located inside the main body 1 and are electrically connected. The main body 1 is provided with a funnel support 4. The hot water output pipe a of the water pressure assembly is connected to the outlet 401 of the funnel support 4. The funnel device 2 is detachably connected to the lower side of the funnel support 4 and is connected to the outlet 401. The funnel support 4 is provided with a position sensor connected in series with the control system 3. The funnel device 2 is provided with a sensing structure that cooperates with the position sensor. When the funnel device 2 is connected to the funnel support 4, the control system 3 senses whether the funnel device 2 is locked in place through the position sensor to start or stop the working circuit of the water pressure assembly.

[0026] This coffee machine utilizes the assembly relationship between the funnel device 2 and the funnel support 4. After the funnel device 2 is assembled into a fixed position, the positioning sensor is triggered. The positioning sensor is connected to the working circuit in the control system 3. The coffee machine can only be operated after the consumer rotates the funnel device 2 to a fixed position (this position is the maximum locking position designed) and triggers the positioning sensor.

[0027] This structure ensures that consumers operate the coffee machine correctly, reducing and eliminating potential safety hazards caused by improper operation from the machine design itself. It also prevents accidents such as coffee liquid and coffee powder splashing everywhere and causing burns of varying degrees to consumers when the funnel slips and falls off during the coffee brewing process, thus further improving the safety of the coffee machine.

[0028] Even if the consumer accidentally removes the funnel device 2 midway through the process, the coffee machine can immediately disconnect the working circuit and cut off the working power of the water pressure component inside the coffee machine, so that the coffee machine stops working immediately and reduces the risk of burns.

[0029] In this embodiment, the positioning sensor is a mechanical sensor; the mechanical sensor is mainly a micro switch 5, the sensing structure includes a protruding structure on the funnel device 2, and a transmission component 6 is provided between the on / off key 51 of the micro switch 5 and the protruding part. After the protruding structure is locked in place, it forms a dynamic contact with the on / off key 51 through the transmission component 6.

[0030] Specifically, the funnel support 4 is provided with a connecting cavity 403 corresponding to the funnel device 2. The inner peripheral wall of the connecting cavity 403 is provided with a snap-fit ​​groove 402 with an open opening. The transmission component 6 extends into the snap-fit ​​groove 402 through the open opening. The outer peripheral wall of the funnel device 2 extends with a screw-fitting protrusion 20 that cooperates with the snap-fit ​​groove 402. After the screw-fitting protrusion 20 is circumferentially screwed into place with the snap-fit ​​groove 402, the screw-fitting protrusion 20 triggers the transmission component 6 as a protruding structure.

[0031] The protruding structure is provided with a pushing inclined surface 210, which gradually lifts the transmission component 6 along the loading direction of the funnel device 2. The funnel device 2 needs to rotate during assembly (in other embodiments, it can slide back and forth). During the loading process, the pushing inclined surface 210 can gradually cooperate with the transmission component 6 until the funnel device 2 rotates or slides to the locking position. The pushing inclined surface 210 can improve the success rate of cooperation.

[0032] The transmission assembly 6 includes a guide bracket 61, a transmission rod 62, and a return spring 63. The transmission rod 62 and the guide bracket 61 form a linear sliding fit, and one end of the transmission rod 62 fits with the protruding structure, while the other end is adjacent to or abuts against the switch 51. The transmission rod 62 is also provided with a spring limiting part 621. The return spring 63 is sleeved on the outside of the transmission rod 62 and abuts against the guide bracket 61 and the spring limiting part 621.

[0033] When the screw-on protrusion 20 in the funnel device 2 rotates to a specific position in the locking groove 402, the screw-on protrusion 20 pushes the transmission rod 62 to move, which in turn pushes the switch 51 to trigger the micro switch to close, starting the working circuit. When the funnel device 2 is disassembled from the funnel support 4, the screw-on protrusion 20 leaves the locking groove 402, and the transmission rod 62 returns to its original position under the elastic potential energy of the return spring 63. The transmission rod 62 then stops pressing on the switch 51, thereby disconnecting the trigger micro switch and stopping the working circuit.

[0034] The guide bracket 61 is fastened to the upper side of the funnel bracket 4 by a connecting structure. The upper part of the guide bracket 61 is provided with a switch mounting cavity 611, and the micro switch 5 is disposed in the switch mounting cavity 611.

[0035] The guide bracket 61 has a guide channel 612 at its lower part. The transmission rod 62 slides in the guide channel 612. A baffle 614 is connected to the upper side of the guide channel 612. The baffle 614 limits the transmission rod 62 and the return spring 63 in the guide channel 612. The return spring 63 abuts between the baffle 614 and the spring limiting part 621. The baffle 614 has a clearance hole 615 corresponding to the guide channel 612. The transmission rod 62 extends out of the switch mounting cavity 611 through the clearance hole 615 and cooperates with the switch key 51.

[0036] The connection structure mainly consists of a connecting through hole 611 and a threaded blind hole 404. The threaded blind hole 404 is opened on the funnel support 4, and the connecting through hole 611 is opened on the guide support 61. By passing screws through the connecting through hole 611 and the threaded blind hole 404, the guide support 61 and the funnel support 4 are assembled and connected.

[0037] A filter screen 9 is fastened inside the connecting cavity 403. The filter screen 9 is spaced apart from the water outlet 401. A sealing ring 10 is sleeved between the outer periphery of the filter screen 9 and the funnel support 4. The top surface of the funnel device 2, which is locked in place, is tightly abutted against the sealing ring 10.

[0038] The filter screen 9 has dispersed water outlet holes 901, which allow hot water to flow evenly into the funnel device 2 and mix thoroughly with the coffee powder inside to extract the coffee solution. This prevents the hot water sprayed from the outlet 401 from directly washing the coffee powder and affecting the extraction effect. The sealing ring 10 not only seals the gap between the filter screen 9 and the funnel support 4, but also seals the gap between the funnel device 2 and the funnel support 4 after the funnel device 2 is locked in place, preventing coffee liquid and coffee powder from splashing everywhere due to high pressure.

[0039] The main body 1 is also provided with a receiving platform 11, which is located below the funnel support 4; a water receiving tray 12 can be detached and installed inside the receiving platform 11, and a coffee container 13 is movably placed above the water receiving tray 12, and a liquid receiving port 131 communicating with the liquid outlet 212 of the funnel device 2 is opened on the container 13.

[0040] The funnel device 2 includes a funnel body 21, an extraction cup 22, and a handle 23. The funnel body 21 has a receiving cavity 211, and the bottom of the receiving cavity 211 has a liquid outlet 212. The extraction cup 22 is housed in the receiving cavity 211 and has a powder receiving cavity 221. The bottom of the powder receiving cavity 221 has an extraction hole 222 that communicates with the receiving cavity 211. The handle 23 is connected to the outer wall of the funnel body 21.

[0041] The main body 1 is also provided with a receiving platform 11, which is located below the funnel support 4; a water receiving tray 12 can be detachably installed inside the receiving platform 11, which can collect the overflowing coffee solution or water for easy centralized cleaning; a coffee container 13 is movably placed above the water receiving tray 12, and a liquid receiving port 131 communicating with the liquid outlet 212 of the funnel device 2 is provided on the container 13.

[0042] The water pressure assembly mainly includes a water supply source, a water pump, and a heating system. The pump's suction end is connected to the water supply source, the pump's discharge end is connected to the heating system's inlet end, and the heating system's outlet end is connected to the outlet via a hot water output pipe. The water pressure assembly is existing technology and will not be described or marked in detail here. Example 2:

[0043] The difference between Example 2 and Example 1 is as follows: See Figure 6As shown, the main body 1 is provided with a reminder device 14, which is electrically connected to the control system 3. When the positioning sensor detects that the funnel device 2 is not locked in place, the reminder device 14 is activated to issue a reminder signal. The reminder device 14 includes a signal indicator light, and / or an LCD display, and / or a buzzer.

[0044] In Embodiment 2, the position sensor can be a limit switch or a signal sensor. The position sensor synchronously transmits the signal to the control system on the coffee machine. The control system then calculates and issues a command, which is then used to inform the consumer that the funnel device is not locked in place by means of the indicator light illuminating or flashing, or by displaying an unlocked prompt on the LCD screen, or by sounding a buzzer. This prevents the coffee machine from continuing to the next step of operation and avoids safety risks caused by improper operation of the coffee machine. Example 3:

[0045] The difference between Example 3 and Example 1 is as follows: See Figure 7 As shown, the positioning sensor can also be a magnetic sensor; the magnetic sensor includes a Hall switch or a reed switch 7, and the sensing structure includes a magnet 8 connected to the funnel device 2. After the magnet 8 is locked in place, it forms a magnetic interaction with the Hall switch or the reed switch 7. The magnetic interaction can also be used to determine whether the funnel device 2 is locked in place.
