This integrated grinding and brewing operation enhances the automation of the coffee machine and improves the user experience.

Description

Technical Field

[0001] This utility model relates to the field of power supply system technology, and in particular to a coffee machine. Background Technology

[0002] Traditional drip coffee machines require manual transfer of ground coffee into the brewing basket, a process that can easily lead to oxidation and aroma loss. They also suffer from issues such as poor sealing of the coffee outlet and steam backflow. Furthermore, most drip coffee machines use a fixed funnel structure, making it impossible to switch the coffee basket position, resulting in cumbersome operation and a poor user experience. Utility Model Content

[0003] The purpose of this invention is to solve the shortcomings of current coffee machines on the market, which require manual transfer of ground coffee powder to the brewing basket, which easily leads to oxidation and loss of aroma, and also makes it impossible to switch the position of the coffee basket. This invention provides a new type of coffee machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a coffee machine, characterized in that it includes a housing, a grinding mechanism and a brewing mechanism disposed in the housing, a coffee powder basket for holding coffee powder, and a driving mechanism for driving the coffee powder basket from the grinding mechanism to the brewing mechanism.

[0005] The housing is also equipped with a control unit, which includes a control board and a solenoid valve that engages or disengages with the coffee powder basket.

[0006] Furthermore, the coffee powder basket has a transmission rack, and the drive mechanism includes a transmission wheel assembly that meshes with the transmission rack, a rack slide rail, and springs disposed at both ends of the rack slide rail.

[0007] Furthermore, the transmission wheel assembly includes a large gear that meshes with the transmission rack and a small gear that meshes with the rack slide rail.

[0008] Furthermore, the bottom of the coffee powder basket has a conical trough for holding coffee powder.

[0009] Furthermore, the end of the coffee powder basket also has a sealing scraper and a push-pull handle.

[0010] Furthermore, the coffee powder basket has a transmission rack, and the transmission mechanism includes a transmission gear that meshes with the transmission rack and a drive motor for driving the transmission gear.

[0011] Furthermore, the drive mechanism consists of several springs for elastically connecting the coffee powder basket to the housing.

[0012] Furthermore, the coffee powder basket has a mounting post for mounting the spring.

[0013] Furthermore, the control unit also includes a sensor for positioning the coffee powder basket.

[0014] Furthermore, the grinding mechanism has a powder outlet communicating with the coffee powder basket below, and the brewing mechanism has a spray nozzle for pouring hot water into the coffee powder basket.

[0015] The beneficial effects of the coffee machine provided by this utility model are as follows: In grinding mode, the user pushes the coffee powder basket into the machine body, causing the solenoid valve to engage with the coffee powder basket. The grinding mechanism then drops the ground coffee powder into the coffee powder basket. Subsequently, in brewing mode, the control board of the control unit controls the solenoid valve to disengage from the coffee powder basket, and the drive mechanism moves the coffee powder basket from the grinding mechanism to the brewing mechanism. This achieves automatic switching of the coffee powder basket position, realizing integrated grinding and operation, improving the automation level of the coffee machine, and thus effectively enhancing the user experience. In addition, when the coffee powder basket moves to the brewing mechanism, it can seal the grinding mechanism, effectively preventing water vapor from entering the grinding mechanism, thereby effectively ensuring the taste of the coffee powder in the grinding mechanism and further improving the user experience.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] See Figure 1-6 The present invention provides a coffee machine 100, which includes a housing 10, a grinding mechanism 11 and a brewing mechanism 12 disposed within the housing 10, a coffee powder basket 20 for holding coffee powder, and a driving mechanism 30 for driving the coffee powder basket 20 to move from the grinding mechanism 11 to the brewing mechanism 12; the housing 10 also includes a control unit, which includes a control board 40 and a solenoid valve 41 that engages with the coffee powder basket 20, and the control board 40 controls the solenoid valve 41 to engage or disengage from the coffee powder basket 20. In the grinding mode, the user pushes the coffee powder basket 20 into the housing 10, causing the solenoid valve 41 to engage with the coffee powder basket 20. The grinding mechanism 11 then drops the ground coffee powder into the coffee powder basket 20. Subsequently, in the brewing mode, the control board 40 of the control unit controls the solenoid valve 41 to disengage from the coffee powder basket 20, and the drive mechanism 30 moves the coffee powder basket 20 from the grinding mechanism 11 to the brewing mechanism 12. This achieves automatic position switching of the coffee powder basket 20, integrating grinding and operation, improving the automation level of the coffee machine 100, and thus effectively enhancing the user experience. Furthermore, when the coffee powder basket 20 moves to the brewing mechanism 12, it can seal the grinding mechanism 11, effectively preventing water vapor from entering the grinding mechanism 11, thereby ensuring the taste of the coffee powder in the grinding mechanism 11 and further enhancing the user experience.

[0030] Example 1:

[0031] like Figure 2-4 As shown, in this embodiment, the coffee powder basket 20 has a transmission rack 21, and the drive mechanism 30 includes a transmission wheel set 31 that meshes with the transmission rack 21, a rack slide rail 32, and springs 33 disposed at both ends of the rack slide rail 32. The transmission wheel set 31 includes a large gear 311 that meshes with the transmission rack 21 and a small gear 312 that meshes with the rack slide rail 32. In this embodiment, in grinding mode, the user pushes the coffee powder basket 20 inward, so that the coffee powder basket 20 is located below the grinding mechanism 11. During the process of the user pushing inward, the transmission rack 21 of the coffee powder basket 20 drives the large gear 311 to drive the small gear 312 to rotate, thereby causing the small gear 312 to push the rack slide rail 32, and causing the rack slide rail 32 to compress the springs 33. At this time, the control board 40 controls the pin of the solenoid valve 41 to abut against the coffee powder basket 20, thereby making the solenoid valve 41 engage with the coffee powder basket 20, and thus preventing the coffee powder basket 20 from moving. In brewing mode, the control board 40 controls the pin of the solenoid valve 41 to rise and separate from the coffee powder basket 20, thereby releasing the engagement between the solenoid valve 41 and the coffee powder basket 20. This allows the rack and pinion slide rail 32 to slide under the elastic force of the spring 33, thereby driving the small gear 312 to drive the large gear 311 to rotate. In turn, the large gear 311 drives the coffee powder basket 20 to return to the brewing mechanism 12 through the transmission rack 21, and the brewing mechanism 12 adds hot water into the coffee powder basket 20 to complete the brewing operation.

[0032] like Figure 2 and 4As shown, the coffee powder basket 20 provided by this utility model has a holding groove 22 at the bottom for holding coffee powder, and the holding groove 22 has a conical structure. Below the grinding mechanism 11 is a powder outlet communicating with the coffee powder basket 20, and the brewing mechanism 12 has a spray nozzle for pouring hot water into the coffee powder basket 20. By setting the holding groove 22 of the coffee powder basket 20 to a conical structure, the amount of coffee powder held in the holding groove 22 can be effectively increased, and the smoothness of the coffee liquid dripping into the coffee cup after the brewing mechanism 12 pours hot water into the holding groove 22 through the spray nozzle can be improved. Furthermore, the coffee powder basket 20 provided by this utility model also has a sealing scraper 24 and a push-pull handle 23 at its end. The sealing scraper 24 scrapes residual coffee powder from the outlet of the grinder 11 into the container 22 during the process of the drive mechanism 30 moving the coffee powder basket 20 from the grinder 11 to the brewing mechanism 12. When the coffee powder basket 20 reaches the brewing mechanism 12, the sealing scraper 24 abuts against the outlet, thus forming a seal in the grinder 11. This effectively prevents water vapor from entering the grinder 11, ensuring the quality and taste of the coffee powder inside. Furthermore, the push-pull handle 23 enhances the ease of operation for the user when pushing and pulling the coffee powder basket 20, further improving the user experience.

[0033] Example 2:

[0034] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the coffee powder basket 20 has a transmission rack 21, and the transmission mechanism includes a transmission gear 34 that meshes with the transmission rack 21 and a drive motor 35 for driving the transmission gear 34. In this embodiment, by using the drive motor 35 to drive the transmission gear 34 to rotate forward or backward, the transmission rack 21 that meshes with the transmission gear 34 drives the coffee powder basket 20 to move, thereby realizing the operation of moving the coffee powder basket 20 to the grinding mechanism 11 or the brewing mechanism 12, further improving the convenience of moving the coffee powder basket 20, and improving the convenience and experience of the user while ensuring the taste of the coffee brewed by the coffee machine 100.

[0035] Example 3:

[0036] like Figure 6As shown, the difference between this embodiment and Embodiment 1 is that the drive mechanism 30 consists of several springs 36 that elastically connect the coffee powder basket 20 to the housing 10. The coffee powder basket 20 has mounting posts 25 for mounting the springs 36. In grinding mode, the user pushes the coffee powder basket 20 inward, positioning it below the grinding mechanism 11. During this inward push, the coffee powder basket 20 compresses the springs 36. At this time, the control board 40 controls the pin of the solenoid valve 41 to abut against the coffee powder basket 20, thereby engaging the solenoid valve 41 with the coffee powder basket 20 and preventing it from moving. In brewing mode, the control board 40 controls the pin of the solenoid valve 41 to rise and separate from the coffee powder basket 20, thereby releasing the engagement between the solenoid valve 41 and the coffee powder basket 20. This allows the coffee powder basket 20 to move and return to the brewing mechanism 12 under the elastic force of the springs 36, and hot water is added to the coffee powder basket 20 using the brewing mechanism 12 to complete the brewing operation. By mounting the spring 36 onto the coffee powder basket 20 using the mounting post 25, the stability of the spring 36 mounted on the coffee powder basket 20 can be effectively improved.

[0037] In addition, such as Figure 1 As shown, the control unit provided by this utility model also includes a sensor for positioning the coffee powder basket 20. By utilizing the sensor, the relative position of the coffee powder basket 20 within the housing 10 can be effectively located, thereby effectively improving the displacement accuracy of the coffee powder basket 20 as it moves to the grinding mechanism 11 or the brewing structure, and consequently, the operational accuracy of the grinding and brewing operations of the coffee machine 100. Furthermore, after the grinding operation is completed, during the process of the drive mechanism 30 driving the coffee powder basket 20 to move to the brewing mechanism 12, the coffee brewing process of the brewing structure is triggered, ensuring that the brewing operation of the brewing mechanism 12 begins immediately after the coffee powder basket 20 moves to it, thereby effectively improving the working efficiency of the coffee machine 100. The control board 40 of the control unit also has a delayed brewing function. After the grinding mechanism 11 completes the grinding of the coffee powder, the operation of the drive mechanism 30 driving the coffee powder basket 20 to move to the brewing mechanism 12 is delayed to achieve pre-infusion, thereby meeting the diverse coffee brewing needs of users.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
