Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and particularly relates to an easy-to-operate coffee machine, and more particularly to a cooperative structure of a movable carrier, a powder pressing device, a transmission mechanism, etc. in the coffee machine. Background Art

[0002] As a popular beverage, the performance and operation convenience of coffee production equipment have always been the focus of consumers. In the design and manufacture of coffee machines, the powder pressing operation is a key link in making high-quality coffee, which directly affects the taste and quality of coffee. However, there are many deficiencies in the design of the powder pressing mechanism of existing coffee machines, bringing many inconveniences to coffee production.

[0003] The powder pressing mechanisms of traditional coffee machines mainly have two types: a fixed powder pressing structure and a separated powder pressing structure. In the fixed powder pressing structure, the powder pressing position coincides with the powder receiving position. Although this design has a simple structure, obvious defects are exposed in the actual use process. Since the powder pressing mechanism and the powder receiving area share the same space, during the powder receiving process, coffee powder is likely to spill, not only causing waste of raw materials, but also polluting the internal environment of the coffee machine. Moreover, during the powder pressing operation, the limited space will restrict the movements of the operator, making the powder pressing operation difficult, and it is difficult to ensure the uniformity and strength of powder pressing, thus affecting the coffee extraction effect.

[0004] The separated powder pressing structure separates the powder pressing position from the powder receiving position. After the user loads coffee powder at the powder receiving position, the powder bowl needs to be manually moved to a dedicated powder pressing station for powder pressing. Although this method optimizes the operation space to a certain extent and avoids the problem of coffee powder spilling, it adds an extra moving step. The operator needs to frequently move the powder bowl between powder receiving and powder pressing, which not only makes the operation process cumbersome, reduces the coffee production efficiency, but also easily makes mistakes during the moving process, resulting in situations such as the powder bowl tipping over and coffee powder spilling out, further affecting the coffee production experience.

[0005] In addition, during the powder pressing process of existing coffee machines, the cooperation between various components is poor. For example, there is a lack of an effective linkage mechanism between the powder pressing device and the powder collecting device, and the operator needs to control their actions separately, increasing the complexity and difficulty of the operation.

[0006] In summary, there are many problems in the powder collecting and powder pressing operations of existing coffee machines, and there is an urgent need for an easy-to-operate coffee machine to solve the above problems. Summary of the Invention

[0007] The object of the present invention is to provide an easy-to-operate coffee machine, so as to solve the problems existing in the powder collection and powder pressing operations of the existing coffee machines, such as coffee powder spilling, complicated operation process, poor component coordination, etc., thereby improving the operation convenience of the coffee machine and enhancing the user experience.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] An easy-to-operate coffee machine includes a frame, a powder pressing device, a powder collection device, and a powder output device. The powder output device defines a powder receiving position, and the powder pressing device defines a powder pressing position. The powder pressing device includes an operation handle and a powder pressing piston, and the operation handle drives the powder pressing piston to move up and down through a transmission mechanism;

[0010] The frame has a movable carrier for placing the powder collection device, and the movable carrier is configured to reciprocate between the powder receiving position and the powder pressing position;

[0011] The transmission mechanism has a rotating shaft, and the rotating shaft is configured to rotate in response to the operation of the operation handle;

[0012] Wherein, the rotating shaft and the movable carrier are connected through a linkage mechanism, so that during the downward movement of the powder pressing piston, the movable carrier synchronously moves from the powder receiving position to the powder pressing position.

[0013] In some embodiments, the linkage mechanism includes a driving wheel fixed on the rotating shaft and a traction member connected between the driving wheel and the movable carrier.

[0014] Further, the traction member is attached to the movable carrier through a telescopic element. When the movable carrier is held at the powder pressing position, the powder pressing piston is configured to continue to move downward by the displacement compensation provided by the telescopic element.

[0015] Further, the telescopic element can be configured as a tension spring, an elastic rope or an elastic metal sheet.

[0016] Further, the driving wheel is a pulley or a gear, and correspondingly, the traction member is a traction rope or a toothed belt.

[0017] Further, the movable carrier is provided with a guide wheel for changing the extending direction of the traction member.

[0018] Further, one end of the traction member is fixed to the movable carrier, and the other end is fixed to the frame or the driving wheel.

[0019] In some embodiments, the movable carrier is connected to the machine frame by a return spring. During the upward movement of the powder pressing piston, the return spring applies a force to the movable carrier in a direction such that the movable carrier returns from the powder pressing position to the powder receiving position.

[0020] Further, the movable carrier includes a rim portion for positioning the powder collecting device and arm portions on both sides of the rim portion. The arm portions are in sliding cooperation with the machine frame, and the sliding structure includes a slider and a chute that are adapted to each other. One of the slider and the chute is disposed on the arm portion, and the other is disposed on the machine frame.

[0021] Further, the transmission mechanism includes a powder pressing gear and a powder pressing rack that mesh with each other.

[0022] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0023] (1) In the coffee machine of the present invention, by providing a movable carrier and a linkage mechanism between the rotating shaft and the movable carrier, an operator only needs to operate the handle to simultaneously move the powder pressing piston and switch the position of the powder collecting device. The movable carrier automatically reciprocates between the powder receiving position and the powder pressing position, avoiding the cumbersome operation of manually moving the powder bowl, greatly simplifying the operation process, improving the coffee making efficiency, and enabling the user to make coffee more quickly and conveniently. In addition, the design of the movable carrier realizes the automatic conversion of the powder collecting device between the powder receiving and powder pressing positions, making reasonable use of the space of the coffee machine. When in the powder receiving position, there is enough space for powder receiving operation to avoid coffee powder spillage; when in the powder pressing position, the movable carrier moves accurately in place, providing a stable space for the powder pressing operation, and the operator can perform the powder pressing operation more conveniently, improving the convenience of the operation.

[0024] (2) In the linkage mechanism, the traction member is attached to the movable carrier through a telescopic element. When the movable carrier is held in the powder pressing position, the powder pressing piston can continue to move downward by the displacement compensation provided by the telescopic element. This design enables the powder pressing piston to still move smoothly and evenly downward by a certain distance after the movable carrier reaches the powder pressing position, ensuring the smoothness and uniformity of the powder pressing process, contributing to improving the coffee extraction effect, and thus enhancing the quality of coffee. In addition, the linkage mechanism between the rotating shaft and the movable carrier, and the setting of the return spring realize the efficient coordinated operation between the powder pressing device and the powder collecting device. The operator only needs to operate the handle to simultaneously control the actions of the powder pressing piston and the movable carrier, and when the powder pressing piston moves upward, the return spring can automatically return the movable carrier to the powder receiving position, improving the automation degree of the coffee machine, reducing manual intervention, and further enhancing the user experience.

[0042] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. The features in the following embodiments can be combined with each other without conflict.

[0043] Embodiment:

[0044] Please refer toFigure 1 and Figure 2 A coffee machine that is easy to operate provided in this embodiment is designed with an overall structure to systematically solve many pain points existing in the powder collection and powder pressing operations of existing coffee machines, such as waste of raw materials caused by coffee powder spilling, low efficiency due to cumbersome operation processes, mechanical failures caused by poor component coordination, etc. Through innovative structural design, the coffee machine 10 realizes a high degree of integration and automation of the powder collection and powder pressing operations, mainly including several key parts such as a frame 100, a powder pressing device 110, a powder collection device 120, and a powder output device 130.

[0045] As the starting link of coffee making, the core function of the powder output device 130 is to accurately output coffee powder. It can be a grinding device with a high-precision grinding function, which can grind coffee beans into evenly sized coffee powder on-site according to different coffee bean characteristics and user taste requirements and then output it; or it can be a storage device for storing pre-ground coffee powder, which directly outputs the coffee powder through an accurate metering system. Please refer to Figure 3 , the powder output device 130 defines a powder receiving position A, which is carefully designed to ensure that the coffee powder can accurately fall into the powder collection device 120 during the output process, effectively avoiding the problem of coffee powder spilling. In practical applications, the powder receiving position A can be equipped with a diversion structure 131 to further optimize the flow path of the coffee powder and improve the powder receiving efficiency.

[0046] The powder pressing device 110 is used to compact the coffee powder in the powder collection device 120 to ensure the effect of subsequent coffee extraction. Please refer to Figure 4 , the powder pressing device 110 defines a powder pressing position B, which includes an operation handle 111 and a powder pressing piston 112. The operation handle 111 drives the powder pressing piston 112 to move up and down through a transmission mechanism 150. When the operator presses down the operation handle 111, the transmission mechanism 150 accurately transmits the movement of the operation handle 111 to the powder pressing piston 112, causing the powder pressing piston 112 to move downward to compact the coffee powder in the powder collection device 120; when the operator releases the operation handle 111, the operation handle 111 drives the powder pressing gear 152 to rotate in the reverse direction through a rotating shaft 151 under the action of a relevant reset structure, and then drives the powder pressing rack 153 and the powder pressing piston 112 to move upward together to return to the initial position. This design not only realizes the precise control of the powder pressing operation but also ensures the reliable return of the powder pressing piston 112 through the reset structure. It can be understood that the relevant reset structure can be a reset torsion spring arranged in the operation handle 111, or a tension spring arranged between the powder pressing piston 112 and the frame 100. It is also possible to use the method of operating the operation handle 111 in the reverse direction to reset the powder pressing piston 112, and this embodiment does not make any limitations.

[0047] The frame 100 is the support structure of the entire coffee machine. It is made of high-strength materials and is used to support and protect various components such as the powder pressing device 110, the powder collecting device 120, and the powder output device 130. The frame 100 has a movable carrier 140 for placing the powder collecting device 120, and the movable carrier 140 can reciprocate between the powder receiving position A and the powder pressing position B. This design enables the powder collecting device 120 to complete powder receiving and powder pressing operations at different positions, avoiding problems such as coffee powder spillage and operation interference caused by sharing the same space for powder receiving and powder pressing in traditional coffee machines. The movement trajectory of the movable carrier 140 is precisely calculated and optimized to ensure smooth and accurate movement during the movement process.

[0048] As Figure 2 shown in the figure, the transmission mechanism 150 has a rotating shaft 151, and the rotating shaft 151 is configured to rotate in response to the operation of the operation handle 111. The rotating shaft 151 and the movable carrier 140 are connected by a linkage mechanism 160. The function of the linkage mechanism 160 is to move the movable carrier 140 synchronously from the powder receiving position A to the powder pressing position B during the downward movement of the powder pressing piston 112. Through this linkage mechanism, the operator only needs to operate the handle 111 to simultaneously achieve the movement of the powder pressing piston 112 and the position switching of the powder collecting device 120, greatly simplifying the operation process and improving the convenience and efficiency of the operation.

[0049] The linkage mechanism 160 is a key component in the present invention to achieve the coordinated movement of the movable carrier 140 and the powder pressing piston 112. Please refer to Figures 5 to 8 , in this embodiment, the linkage mechanism 160 includes a driving wheel 161 fixedly connected to the rotating shaft 151, and a traction member 162 connected between the driving wheel 161 and the movable carrier 140. The driving wheel 161 can be a pulley or a gear. Correspondingly, the traction member 162 is a traction rope or a toothed belt. Please refer to Figure 7 and Figure 8 , as the first implementation method of the linkage mechanism 160 in this embodiment, the driving wheel 161 is a pulley and the traction member 162 is a traction rope. Please refer to Figure 5 and Figure 6 , as the second implementation method of the linkage mechanism 160 in this embodiment, the driving wheel 161 is a gear and the traction member 162 is a toothed belt. This design can be flexibly selected according to actual needs and spatial layout to achieve different transmission effects. For example, in a relatively compact space, a combination of a pulley and a traction rope can be selected to reduce the volume of the mechanism; in a case where high transmission accuracy is required, a combination of a gear and a toothed belt can be selected to improve the transmission stability.

[0050] In one embodiment, the movable carrier 140 is provided with a guide wheel 163 that changes the extension direction of the traction member 162. The arrangement of the guide wheel 163 can optimize the layout and movement path of the traction member 162, making the movement of the movable carrier 140 smoother and more accurate. For example, when the internal space layout of the coffee machine is relatively complex, by reasonably arranging the guide wheel 163, the traction member 162 can bypass some obstacles, ensuring that the movable carrier 140 can move smoothly between the powder receiving position A and the powder tamping position B. The material and rotation accuracy of the guide wheel 163 are carefully selected and designed to reduce friction and wear and improve the service life of the linkage mechanism.

[0051] In one embodiment, one end of the traction member 162 is fixedly connected to the movable carrier 140, and the other end is fixedly connected to the frame 100 or the driving wheel 161. This connection method ensures the stability and reliability of the traction member 162 during power transmission and control of the movement of the movable carrier 140. When the rotating shaft 151 rotates, the driving wheel 161 rotates accordingly, and the length of the traction member 162 changes under the drive of the driving wheel 161, thereby driving the movable carrier 140 to move. In practical applications, the tension and length of the traction member 162 can be adjusted according to the moving distance and load conditions of the movable carrier 140 to ensure the normal operation of the linkage mechanism. It should be noted that when the driving wheel 161 is a gear, if the other end of the traction member is fixedly connected to the driving wheel 161, a driving wheel with a larger diameter needs to be set to ensure that the toothed belt has enough moving stroke.

[0052] Continue to refer to Figures 5 to 8 , in one embodiment, the traction member 162 is attached to the movable carrier 140 through a telescopic element 164. The telescopic element 164 can be configured as a tension spring, an elastic cord or an elastic metal sheet. When the movable carrier 140 is held at the powder tamping position B, the powder tamping piston 112 can continue to move downward by means of the displacement compensation provided by the telescopic element 164. This design allows the powder tamping piston 112 to continue to move downward a certain distance after the movable carrier 140 reaches the powder tamping position B to complete the powder tamping operation. At the same time, the displacement compensation provided by the telescopic element 164 can ensure the smoothness and uniformity of the powder tamping process and improve the quality of the coffee.

[0053] For example, when a tension spring is used as the telescopic element 164, one end of the tension spring is fixed to the movable carrier 140, and the other end is fixed to the end of the traction member 162. During the downward movement of the powder pressing piston 112, the movable carrier 140 first moves to the powder pressing position B with the traction member 162 and is positioned at the powder pressing position B. Specifically, a limiting member can be provided for positioning. At this time, the powder pressing piston 112 continues to move downward, and the tension spring is stretched, providing a certain buffer and displacement compensation for the powder pressing piston 112, making the powder pressing process smoother. The elastic coefficient of the tension spring is precisely calculated to ensure that while providing sufficient displacement compensation, it will not generate excessive resistance to the movement of the powder pressing piston 112.

[0054] Please refer to Figure 9 , in an embodiment, the movable carrier 140 is used to carry the powder collecting device 120. It includes a rim portion 141 for positioning the powder collecting device 120 and arm portions 142 located on both sides of the rim portion 141. The arm portions 142 are cooperatively engaged with the frame 100 through a sliding structure. The sliding structure includes a slider and a chute that are adapted to each other. In this embodiment, the slider 143 is disposed on the arm portion 142, and the chute (not shown in the figure) is disposed on the frame 100. In another embodiment, the positions of the slider 143 and the chute can be interchanged to meet different installation requirements. The design of this sliding structure ensures the stability and accuracy of the movable carrier 140 during movement. The slider 143 slides in the chute, which can effectively limit the movement direction of the movable carrier 140, enabling it to perform a linear reciprocating motion only between the powder receiving position A and the powder pressing position B. At the same time, the sliding structure facilitates the installation and positioning of the powder collecting device 120. When the powder collecting device 120 is placed on the rim portion 141 of the movable carrier 140, it can be accurately positioned to ensure that the powder collecting device 120 will not shake or shift during movement.

[0055] In practical applications, to ensure the smoothness of the cooperation between the slider 143 and the chute, a lubricating device can be provided in the chute, such as applying lubricating oil or installing grease, to further reduce the friction between the slider 143 and the chute and extend the service life of the sliding structure. The selection and installation position of the lubricating device are carefully designed to avoid contaminating the coffee powder.

[0056] Refer to Figure 5 and Figure 7, in some other embodiments of the present invention, the transmission mechanism 150 includes a powder pressing gear 152 and a powder pressing rack 153 that mesh with each other. The powder pressing rack 153 is fixedly connected to the piston 112, and the powder pressing gear 152 is fixedly connected to the rotating shaft 151. When the operator operates the handle 111, the handle 111 drives the rotating shaft 151 to rotate, and the powder pressing gear 152 on the rotating shaft 151 rotates accordingly. Since the powder pressing gear 152 meshes with the powder pressing rack 153, the rotation of the powder pressing gear 152 drives the powder pressing rack 153 to move linearly, and the powder pressing rack 153 is fixedly connected to the powder pressing piston 112, thereby realizing the up and down movement of the powder pressing piston 112.

[0057] This cooperation mode of the powder pressing gear 152 and the powder pressing rack 153 realizes the precise control of the powder pressing piston 112 by the handle 111. The tooth profile design of the powder pressing gear 152 and the powder pressing rack 153 can ensure the accuracy and stability of the transmission, and avoid problems such as slipping or transmission errors that may occur in the traditional transmission mode. At the same time, this transmission structure has a high transmission efficiency, can effectively transmit the force of the handle 111 to the powder pressing piston 112, and ensure the stability and reliability of the powder pressing operation. In practical applications, the materials and processing technologies of the powder pressing gear 152 and the powder pressing rack 153 are optimized to improve their wear resistance and transmission accuracy.

[0058] Continue to refer to Figures 5 to 8 , in one embodiment, the movable carrier 140 is connected to the frame 100 through a return spring 165. During the upward movement of the powder pressing piston 112, the return spring 165 applies a force to the movable carrier 140 in a direction that enables the movable carrier 140 to return from the powder pressing position B to the powder receiving position A. The setting of the return spring 165 realizes the automatic reset function of the movable carrier 140. When the operator completes the powder pressing operation and releases the handle 111, the powder pressing piston 112 moves upward under the action of the relevant reset structure. At the same time, the return spring 165 begins to play a role. It applies a force to the movable carrier 140 in the direction of the powder receiving position A, so that the movable carrier 140 automatically returns from the powder pressing position B to the powder receiving position A.

[0059] This automatic reset function further simplifies the operation process and improves the automation level of the coffee machine. The operator does not need to manually move the movable carrier 140 back to the powder receiving position A, reducing manual intervention, lowering the operation difficulty, and enhancing the user experience. In practical applications, the elastic coefficient of the reset spring 165 can be reasonably selected according to the weight and moving distance of the movable carrier 140. If the elastic coefficient of the reset spring 165 is too small, it may not provide enough force to enable the movable carrier 140 to return to the powder receiving position A in time; if the elastic coefficient is too large, it may cause the movable carrier 140 to return too quickly, generating an impact and affecting the stability and service life of the coffee machine. Therefore, precise mechanical analysis and experimental verification are required when designing and selecting the reset spring 165.

[0060] When the coffee machine of the present invention is in use, the operator first outputs coffee powder into the powder collecting device 120, and at this time, the powder collecting device 120 is located at the powder receiving position A. Then, the operator holds the operating handle 111 and presses it downward. The operating handle 111 drives the rotating shaft 151 to rotate through the transmission mechanism 150, and the driving wheel 161 on the rotating shaft 151 rotates accordingly. The traction member 162 drives the movable carrier 140 to move from the powder receiving position A to the powder pressing position B under the drive of the driving wheel 161. At the same time, the powder pressing gear 152 and the powder pressing rack 153 in the transmission mechanism 150 cooperate to move the powder pressing piston 112 downward.

[0061] When the movable carrier 140 reaches the powder pressing position B, the powder pressing piston 112 continues to move downward under the displacement compensation action of the telescopic element 164 to compact the coffee powder in the powder collecting device 120. After the powder pressing operation is completed, the operator releases the operating handle 111. The powder pressing piston 112 moves upward under the action of the reset structure, and at the same time, the reset spring 165 causes the movable carrier 140 to return from the powder pressing position B to the powder receiving position A, waiting for the next powder receiving and powder pressing operations.

[0062] Compared with traditional coffee machines, the present invention has the following significant advantages:

[0063] The operator only needs to operate the handle 111 to simultaneously achieve the movement of the powder pressing piston 112 and the switching of the position of the powder collecting device 120, avoiding the cumbersome operation of manually moving the powder bowl in traditional coffee machines, greatly simplifying the operation process, and improving the coffee making efficiency.

[0064] The design of the movable carrier 140 realizes the automatic conversion of the powder collecting device 120 between the powder receiving and powder pressing positions, making reasonable use of the space of the coffee machine. When at the powder receiving position A, there is enough space for powder receiving operation to avoid coffee powder spilling; when at the powder pressing position B, the movable carrier 140 moves accurately in place, providing a stable space for the powder pressing operation.

[0065] The traction member 162 in the linkage mechanism is attached to the movable carrier 140 through the telescopic element 164. When the movable carrier 140 is maintained at the powder compacting position B, the powder compacting piston 112 can continue to move downward by means of the displacement compensation provided by the telescopic element 164, thereby ensuring the stability and uniformity of the powder compacting process, helping to improve the coffee extraction effect, thereby improving the quality of the coffee. After professional tasting, the coffee made using the coffee machine of the present invention has a mellower taste and a richer aroma.

[0066] The linkage mechanism 160 between the rotating shaft 151 and the movable carrier 140, and the setting of the return spring 165, realize the efficient cooperation between the powder pressing device 110 and the powder collecting device 120. The operator only needs to operate the handle 111 to control the movement of the powder pressing piston 112 and the movable carrier 140 at the same time, and when the powder pressing piston 112 moves upward, the return spring 165 can automatically return the movable carrier 140 to the powder receiving position A, reducing manual intervention. This highly automated design reduces the skill requirements of the operator and improves the stability and consistency of coffee making.

[0067] To sum up, the easy-to-operate coffee machine of the present invention solves the problems existing in the existing coffee machines in powder collection and pressing operations through a unique structural design and linkage mechanism. It has the advantages of convenient operation, reasonable space utilization, stable pressed powder quality and high degree of automation, and can provide users with a better coffee making experience.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
