Description
Technical Field
[0001] This utility model is a portable coffee cup that can be ground and brewed, belonging to the field of portable coffee cups. Background Technology
[0002] With changing lifestyles, more and more people enjoy drinking coffee outdoors, while traveling, or in the office. Therefore, portability has become a crucial design requirement for coffee makers. Portable coffee makers that can grind and brew can meet users' coffee needs in different scenarios, allowing them to enjoy fresh coffee anytime, anywhere. In existing technology, after pouring coffee beans into the grinding cylinder, rotating the crank utilizes a double-bearing fixing mechanism to drive the CNC steel grinding core to grind the coffee beans into a fine powder for easy brewing. However, when the coffee beans are being ground by the CNC steel grinding core inside the grinding cylinder, the CNC steel grinding core is located in the middle of the grinding cylinder. Coffee beans are dispersed around the CNC steel grinding core. During the grinding process, because the weight of the coffee powder is less than that of the coffee beans, and the CNC steel grinding core is constantly rotating, the inertia generated by the rotation will transport the coffee powder to the inner wall of the grinding cylinder. Then, the coffee beans will rub and squeeze the coffee powder, which will easily cause the coffee powder initially ground to stick to the inner wall of the grinding cylinder. The coffee powder stuck to the inner wall of the grinding cylinder cannot be ground completely finely. The uneven coarseness of the coffee powder can easily affect the overall taste of the coffee when brewing. Therefore, it is necessary to design a portable coffee cup that can grind and brew coffee to reduce the amount of coffee powder sticking to the inner wall of the grinding cylinder. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable coffee cup that can grind and brew coffee, so as to solve the problems mentioned in the background art. This utility model reduces the amount of coffee powder adhering to the inner wall of the grinding cylinder during the grinding process, thereby improving the fineness of the ground coffee powder.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a portable coffee cup for grinding and brewing, comprising a coffee cup, an anti-slip pad installed on the top of the coffee cup, a transmission plate installed at the end of the coffee cup away from the anti-slip pad, a grinding cylinder installed on the side of the transmission plate away from the coffee cup, a transmission shaft installed inside the grinding cylinder, a CNC steel grinding core installed on the transmission shaft, a support base plate installed at the bottom of the grinding cylinder, a heating cup installed at the bottom of the support base plate, a control button installed on the outer wall of the heating cup, anti-scalding rings fitted on the outer sides of both the coffee cup and the heating cup, a cleaning component installed at the bottom of the transmission plate, a crank installed inside the grinding cylinder, and a fixing component installed on the side of the transmission plate near the grinding cylinder.
[0005] Furthermore, a mounting base is installed above the coffee cup, and an anti-slip pad is installed on the side of the mounting base away from the coffee cup. The CNC steel grinding core is located on the upper side of the supporting base plate, and a heating plate is installed inside the heating cup.
[0006] Furthermore, an mounting sleeve is installed on one side of the crank, and a limiting post is installed on the outer wall of the transmission plate. The outer diameter of the limiting post is connected to the inner diameter of the mounting sleeve, and the mounting sleeve is inserted into the limiting post.
[0007] Furthermore, the cleaning component includes a retaining ring, a retaining ring is installed at the bottom of the transmission plate, the inner diameter of the retaining ring is connected to the diameter of the transmission shaft, the retaining ring is sleeved on the transmission shaft, a sleeve is installed on the outer wall of the retaining ring, a connecting rod is installed inside the sleeve, and a scraper is installed at the end of the connecting rod away from the sleeve.
[0008] Furthermore, the end of the connecting rod away from the scraper is inserted into the sleeve, and a limiting block is installed at the end of the connecting rod inside the sleeve. The limiting block is in contact with the inner wall of the sleeve, and a telescopic spring is installed on the side of the limiting block away from the connecting rod. The other end of the telescopic spring is installed on the sleeve.
[0009] Furthermore, the fixing component includes a support plate, and two support plates are symmetrically installed on the side of the transmission plate near the coffee cup. A positioning ring is installed between the two support plates, and four buffer springs are evenly installed on the inner wall of the positioning ring. A clamping plate is installed on the side of each of the four buffer springs away from the positioning ring.
[0010] Furthermore, the positioning ring is equipped with insertion rods on both sides near the support plate. The insertion rods are mounted on the support plate, and a fixing block is installed at one end of the insertion rod located on the outside of the support plate. A fixing ring is installed on the transmission plate, and the outer wall of the fixing ring has a threaded structure. The coffee cup is installed on the outside of the fixing ring.
[0011] The beneficial effects of this utility model are as follows: This utility model provides a portable coffee cup that can grind and brew coffee beans. By fitting the mounting sleeve at one end of the crank onto the limiting post installed on one side of the transmission plate, and then rotating the crank clockwise, the CNC steel grinding core inside the grinding cylinder is driven to rotate and grind the coffee beans, thus improving the convenience of coffee bean grinding for coffee lovers traveling outdoors.
[0012] The thrust generated by the rebound of the telescopic spring drives the limiting block to move inside the sleeve. As the limiting block moves, it drives the connecting rod to move outward from the sleeve, so that the scraper installed on the other side of the connecting rod fits against the inner wall of the grinding cylinder. The scraper is made of rubber and can deform according to the curvature inside the grinding cylinder. Both sides of the scraper are inclined surfaces with a certain angle to the inner wall of the grinding cylinder, which makes it easy to scrape off the coffee powder adhering to the inner wall of the grinding cylinder, so that the coffee powder can be fully ground, improving the fineness of the coffee powder and enhancing the taste of the coffee when brewing.
[0013] Insert one end of the crank into the four clamping plates installed inside the positioning ring. The outer wall of the crank presses the four clamping plates outwards, thereby compressing the buffer spring. When the buffer spring rebounds after being compressed, it generates a thrust opposite to the compressive force, causing the four clamping plates to fit against the outer wall of the crank, clamping the crank and restricting its range of motion inside the top cover. This prevents the mounting sleeve at one end of the crank from deforming and being unable to be installed on the limiting post installed on the outside of the transmission plate. It also reduces the possibility of the CNC steel grinding core not being able to rotate properly to grind coffee beans due to deformation of the mounting sleeve on the crank.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figures 1-4 This utility model provides a technical solution: a portable coffee cup for grinding and brewing, including a coffee cup 1, an anti-slip mat 8 installed on the top of the coffee cup 1, a transmission plate 6 installed at the end of the coffee cup 1 away from the anti-slip mat 8, a grinding cylinder 2 installed on the side of the transmission plate 6 away from the coffee cup 1, a transmission shaft 9 installed inside the grinding cylinder 2, a CNC steel grinding core 10 installed on the transmission shaft 9, a support base plate 11 installed at the bottom of the grinding cylinder 2, a heating cup 3 installed at the bottom of the support base plate 11, a control button 4 installed on the outer wall of the heating cup 3, anti-scalding rings 5 fitted on the outer sides of both the coffee cup 1 and the heating cup 3, a cleaning component installed at the bottom of the transmission plate 6, and a crank 12 installed inside the grinding cylinder 2. A fixing component is installed on the side of the transmission plate 6 near the grinding cylinder 2. A mounting base 7 is installed above the coffee cup 1. An anti-slip pad 8 is installed on the side of the mounting base 7 away from the coffee cup 1. The CNC steel grinding core 10 is located on the upper side of the supporting base plate 11. A heating plate is installed inside the heating cup 3. A mounting sleeve 13 is installed on one side of the crank 12. A limit post 17 is installed on the outer wall of the transmission plate 6. The outer diameter of the limit post 17 is connected to the inner diameter of the mounting sleeve 13. The mounting sleeve 13 is inserted into the limit post 17. The anti-scalding ring 5 can prevent the hands from being isolated from the hot water inside the coffee cup 1 and the grinding cylinder 2 when holding the coffee cup 1 and the heating cup 3, reducing the probability of being scalded when drinking coffee.
[0024] Please see Figure 4 and Figure 5The cleaning component includes a retaining ring 16. A retaining ring 16 is installed at the bottom of the transmission plate 6. The inner diameter of the retaining ring 16 is connected to the diameter of the transmission shaft 9. The retaining ring 16 is sleeved on the transmission shaft 9. A sleeve 18 is installed on the outer wall of the retaining ring 16. A connecting rod 15 is installed inside the sleeve 18. A scraper 14 is installed at the end of the connecting rod 15 away from the sleeve 18. The end of the connecting rod 15 away from the scraper 14 is inserted inside the sleeve 18. A limit block 20 is installed at the end of the connecting rod 15 inside the sleeve 18. The limiting block 20 is fitted to the inner wall of the sleeve 18. A telescopic spring 19 is installed on the side of the limiting block 20 away from the connecting rod 15. The other end of the telescopic spring 19 is installed on the sleeve 18. The pushing force generated when the telescopic spring 19 rebounds drives the limiting block 20 to move forward, thereby pushing the connecting rod 15 to move to the outside of the sleeve 18. This pushes the scraper 14 to move to fit against the inner wall of the grinding cylinder 2, making it easier for the scraper 14 to clean the coffee powder adhering to the inner wall of the grinding cylinder 2.
[0025] Please see Figure 6 The fixing components include a support plate 22. Two support plates 22 are symmetrically installed on the side of the transmission plate 6 near the coffee cup 1. A positioning ring 23 is installed between the two support plates 22. Four buffer springs 24 are evenly installed on the inner wall of the positioning ring 23. Clamping plates 25 are installed on the side of the four buffer springs away from the positioning ring 23. Insertion rods 26 are installed on both sides of the positioning ring 23 near the support plate 22. The insertion rods 26 are installed on the support plate 22. A fixing block 27 is installed at the end of the insertion rod 26 located on the outside of the support plate 22. A fixing ring 21 is installed on the transmission plate 6. The outer wall of the fixing ring 21 has a threaded structure. The coffee cup 1 is installed on the outside of the fixing ring 21. Through the cooperation of the support plate 22, the insertion rod 26 and the fixing block 27, the position of the positioning ring 23 can be fixed, so that the positioning ring 23 always faces upward, which makes it easy to insert the crank 12 between the four clamping plates 25.
[0026] Detailed Implementation: By fitting the mounting sleeve 13 at one end of the crank 12 onto the limiting post 17 installed on one side of the transmission plate 6, and then rotating the crank 12 clockwise, the CNC steel grinding core 10 inside the grinding cylinder 2 is driven to rotate and grind the coffee beans, improving the convenience of coffee bean grinding for outdoor coffee lovers. The thrust generated by the rebound of the telescopic spring 19 drives the limiting block 20 to move within the sleeve 18. Simultaneously, the limiting block 20 moves the connecting rod 15 outward from the sleeve 18, causing the scraper 14 installed on the other side of the connecting rod 15 to fit against the inner wall of the grinding cylinder 2. The scraper 14 is made of rubber and can deform according to the curvature inside the grinding cylinder 2. Both sides of the scraper 14 are inclined surfaces, forming an angle with the inner wall of the grinding cylinder 2, facilitating the scraping of coffee powder adhering to the inner wall of the grinding cylinder 2, thus improving the grinding efficiency of the coffee beans. The coffee powder falls back into the grinding cylinder 2 and can be fully ground by the CNC steel grinding core 10, improving the fineness of the coffee powder and enhancing the taste of the coffee. One end of the crank 12 is inserted between the four clamping plates 25 installed inside the positioning ring 23. The outer wall of the crank 12 squeezes the four clamping plates 25 outwards, thereby squeezing the buffer spring 24. When the buffer spring 24 rebounds after being squeezed, it generates a thrust opposite to the squeezing force, so that the four clamping plates 25 fit against the outer wall of the crank 12, clamping the crank 12 and limiting the range of motion of the crank 12 inside the coffee cup 1. This prevents the mounting sleeve 13 at one end of the crank 12 from deforming and failing to be installed on the limiting post 17 installed on the outside of the transmission plate 6, reducing the possibility that the CNC steel grinding core 10 cannot be driven to rotate properly to grind the coffee beans due to the deformation of the mounting sleeve 13 on the crank 12.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
