Description

Technical Field

[0001] This utility model relates to the field of water cup technology, and in particular to a water cup specifically designed for Parkinson's disease. Background Technology

[0002] Parkinson's disease is a common neurodegenerative disease that typically affects people over 65 years of age. According to statistics, 1.7 out of every 100 people have Parkinson's disease, and the incidence rate is as high as 1.7%.

[0003] Parkinson's patients often encounter the following problems: First, hand tremors cause water in the cup to spill; second, due to muscle stiffness, they cannot align the cup spout with their mouth; in addition, they cannot hold the cup tightly and it is easy to drop it.

[0004] Most existing water cups designed for Parkinson's disease patients are designed to rotate 360 ​​degrees. However, since Parkinson's patients often experience hand tremors, while 360-degree rotation can solve the problem of the drinking direction being affected by the tremors, it cannot adapt to the direction of the center of gravity during rotation. As a result, Parkinson's patients still cannot fully align the spout when using water cups with existing technology, leading to spillage. Furthermore, due to hand tremors, Parkinson's patients also have some difficulty gripping the handle of the water cup. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing technologies lack anti-shake effects and cannot adapt to the direction of the center of gravity during rotation, resulting in water cups being prone to spilling or falling. To address this, we propose a water cup specifically designed for Parkinson's disease.

[0006] The main technical solution is as follows: a water cup for Parkinson's disease, comprising a base shell, a cup shell, and a water-holding shell. The cup shell is fixedly connected to the upper surface of the base shell. A drinking spout is connected to one side surface of the water-holding shell. A ball bearing is embedded in the inner bottom wall of the cup shell. A shaft is connected around the inner wall of the ball bearing. One end of the shaft is fixedly connected to the lower surface of the water-holding shell. Equidistant ball bearing seats are installed around the inner wall of the cup shell. Each ball bearing seat is connected to a ball that abuts against the outer surface of the water-holding shell.

[0007] The base housing contains a battery, controller, servo motor, and infrared sensor. The drive end of the servo motor is fixedly connected to a crank-rocker structure. An upper hinge seat and a lower hinge seat are symmetrically installed on one side surface of the cup shell. A double four-bar linkage structure with an overall quadrilateral distribution is connected between the upper hinge seat and the lower hinge seat. The crank-rocker structure and the double four-bar linkage structure are hinged.

[0008] Preferably, the drinking spout is connected to the interior of the water-holding shell, and an internal frame is installed on the side of the water-holding shell near the drinking spout, with a counterweight metal strip placed inside the internal frame.

[0009] Preferably, the inner bottom wall of the cup shell is provided with a bearing groove for installing the ball bearing, and the circumferential surface of the cup shell is provided with seat slots at equal intervals for installing the ball bearing seat.

[0010] Preferably, the servo motor and the infrared sensor are both connected to the controller and the battery, and the battery is connected to the controller.

[0011] The bottom surface of the cup shell is provided with an annular groove, and a receiving coil connected to the storage battery is located in the annular groove. Each receiving coil is equipped with a receiving coil holder that generates electromagnetic induction with it.

[0012] Preferably, the outer shell of the cup has an infrared emission hole on its bottom surface facing the infrared sensor.

[0013] Preferably, the crank rocker structure includes a main drive rod and a crank rod, and the double four-bar linkage structure includes a set of laterally symmetrical upper and lower diagonal rods, as well as a vertical grip rod;

[0014] The end of the main drive rod away from the crank rod is fixedly connected to the drive end of the servo motor, and the main drive rod and the crank rod are hinged together.

[0015] The upper and lower inclined rods are hinged at their ends away from the vertical grip rod, respectively, inside the upper and lower hinge seats. The other ends of the upper and lower inclined rods, closer to the vertical grip rod, are hinged to the vertical grip rod.

[0016] Preferably, a cushioning pad is fixedly connected to the inner wall surface of the vertical grip bar near the upper inclined bar.

[0017] Preferably, a water level limit plate is installed inside the water-holding shell, and a top cover is snapped on the upper surface of the water-holding shell. A set of symmetrical snap plates are fixedly connected to the side of the top cover near the drinking spout, and the snap plates are snapped onto the two sides of the drinking spout.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] In this invention, firstly, the shaft rotates inside the ball bearing, thereby driving the water-holding shell to rotate inside the cup shell. This, combined with the rolling balls installed around the inner wall of the cup shell that abut against the outer surface of the water-holding shell, creates a structural body that provides stable support for the water-holding shell while allowing it to rotate flexibly. This achieves self-adaptive rotation, improving the convenience and stability of drinking water and reducing the possibility of water spillage.

[0020] In addition, when the water-filled shell deflects, the weight of the counterweight metal strip shifts the center of gravity toward the drinking spout, enabling adaptive rotation. This helps the drinking spout automatically align with the mouth, solving the problem that Parkinson's patients cannot align the cup outlet with their mouths due to muscle stiffness, and reducing water spillage.

[0021] In this invention, the infrared sensor inside the base housing can automatically detect when the cup leaves the water cup and transmit the signal to the controller. The controller controls the servo motor to drive the crank rocker structure, which in turn drives the double four-bar linkage structure to move, so that the vertical grip bar can hold the Parkinson's patient's hand against the outer surface of the cup shell, thus achieving the purpose of clamping. This solves the problem that patients cannot hold the cup tightly due to hand tremors, thereby preventing the cup from falling. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0030] Reference Figures 1-6 As shown, this utility model provides a technical solution: a water cup for Parkinson's disease, including a base shell 1, a cup shell 2 and a water-holding shell 3, wherein the cup shell 2 is fixedly connected to the upper surface of the base shell 1.

[0031] In this embodiment: Since the base housing 1 is equipped with a battery 11, a controller 15, a servo motor 14 and an infrared sensor 16, and the servo motor 14 and the infrared sensor 16 are both connected to the controller 15 and the battery 11, and the battery 11 is connected to the controller 15, and since the receiving coil 13 connected to the battery 11 is equipped with a receiving coil base that generates electromagnetic induction with it, the water cup of this practical design can achieve the purpose of wireless charging.

[0032] Furthermore, an annular groove 12 is provided on the bottom surface of the cup shell 2. A receiving coil 13 connected to the battery 11 is located in the annular groove 12. Each receiving coil 13 is equipped with a receiving coil seat that generates electromagnetic induction. An infrared emission hole 17 is provided on the bottom surface of the cup shell 2 facing the infrared sensor 16. A crank rocker structure 201 is fixedly connected to the drive end of the servo motor 14. An upper hinge seat 22 and a lower hinge seat 21 are symmetrically installed on one side surface of the cup shell 2. A double four-bar structure 202 with an overall quadrilateral distribution is connected between the upper hinge seat 22 and the lower hinge seat 21. The crank rocker structure 201 and the double four-bar structure 202 are in a hinged relationship.

[0033] Therefore, during use by Parkinson's patients, the infrared sensor 16 inside the base housing 1 can receive and reflect reflected signals through the infrared emission hole 17 and the table where the cup is placed. When the Parkinson's patient removes the cup from the table using the double four-bar linkage 202, the infrared sensor 16 automatically detects the removal of the cup, i.e., the intensity of the reflected signal gradually weakens until it disappears. At this time, the infrared sensor 16 converts this situation into an electrical signal and transmits the signal to the controller 15. The controller 15 controls the servo motor 14 to drive the crank rocker structure 201, which in turn drives the double four-bar linkage 202 to move, so that the double four-bar linkage 202 holds the Parkinson's patient's hand against the outer surface of the cup housing 2, achieving a clamping purpose. This solves the problem that the patient cannot hold the cup tightly due to hand tremors, thus preventing the cup from falling.

[0034] Secondly, since a drinking spout 31 is connected to one side surface of the water-holding shell 3, and the drinking spout 31 is connected to the interior of the water-holding shell 3, a ball bearing 6 is embedded in the inner bottom wall of the cup shell 2, and a bearing groove 5 for installing the ball bearing 6 is opened in the inner bottom wall of the water-holding shell 3. A shaft 7 is connected around the inner wall of the ball bearing 6, and one end of the shaft 7 is fixedly connected to the lower surface of the water-holding shell 3. Equivalently spaced ball seats 9 are installed around the inner wall of the cup shell 2, and seat slots for installing the ball seats 9 are opened at equal intervals around the surface of the cup shell 2. The ball seats 9 are all connected to balls 10 that abut against the outer surface of the water-holding shell 3.

[0035] Thus, the shaft 7 rotates inside the ball bearing 6, causing the water-holding shell 3 to rotate inside the cup outer shell 2. In conjunction with the rolling balls 10 installed around the inner wall of the cup outer shell 2, which roll inside the ball bearing seat 9 and abut against the outer surface of the water-holding shell 3, the base shell 1, the cup outer shell 2, and the water-holding shell 3 form a structural body that provides stable support for the water-holding shell 3 and allows it to rotate flexibly. This achieves the purpose of adaptive rotation, improves the convenience and stability of drinking water, and reduces the possibility of water spillage.

[0036] Since the water-holding shell 3 has an internal frame 33 installed on the side near the drinking spout 31, and a counterweight metal strip 34 is placed inside the internal frame 33, when the water-holding shell 3 deflects, the weight of the counterweight metal strip 34 inside the internal frame 33 will cause the center of gravity to shift towards the drinking spout 31, thereby achieving adaptive rotation.

[0037] Reference Figures 1-6 As shown, in this embodiment: the crank rocker structure 201 includes a main drive rod 18 and a crank rod 19, and the double four-bar linkage structure 202 includes a set of transversely symmetrical upper inclined rods 24 and lower inclined rods 23, as well as a vertical grip rod 25. A buffer pad 26 is fixedly connected to the inner wall surface of the vertical grip rod 25 near the upper inclined rod 24.

[0038] The end of the main drive lever 18 away from the crank lever 19 is fixedly connected to the drive end of the servo motor 14, and the main drive lever 18 and the crank lever 19 are in a hinged relationship.

[0039] The ends of the upper inclined rod 24 and the lower inclined rod 23 away from the vertical grip rod 25 are respectively hinged inside the upper hinge seat 22 and the lower hinge seat 21, and the other ends of the upper inclined rod 24 and the lower inclined rod 23 near the vertical grip rod 25 are hinged to the vertical grip rod 25.

[0040] In this embodiment: during the process of the servo motor 14 driving the crank rocker structure 201 and thus driving the double four-bar linkage structure 202, the servo motor 14 first drives the main drive rod 18 to rotate by -140°. The main drive rod 18 then drives the crank rod 19 to rotate hingedly, while displacing it in the direction of the drinking spout 31. Then, the crank rod 19 drives the upper inclined rod 24 and the lower inclined rod 23 to rotate hingedly inside the upper hinge seat 22 and the lower hinge seat 21, respectively. Due to the quadrilateral motion characteristics of the double four-bar linkage structure 202, when the upper inclined rod 24 and the lower inclined rod 23 drive the vertical grip rod 25 to rotate hingedly close to the cup outer shell 2, the rotation angles of the upper inclined rod 24 and the lower inclined rod 23 are the same.

[0041] In addition, the buffer pad 26 fixedly connected to the vertical grip bar 25 can provide cushioning protection for the clamping movement.

[0042] Reference Figures 1-2 As shown, a water level limit plate 32 is installed inside the water-holding shell 3. The upper surface of the water-holding shell 3 is covered with a top cover 4 by a snap-fit. A set of symmetrical snap-fit ​​plates 41 are fixedly connected to the side of the top cover 4 near the drinking spout 31. The snap-fit ​​plates 41 are snapped onto the two sides of the drinking spout 31.

[0043] In this embodiment, a water level limit plate 32 is installed inside the water-containing shell 3 to prevent excessive water from overflowing.

[0044] The upper surface of the water-holding shell is sealed by a snap-on cover 4, and the snap-on plate 41 of the cover 4 is snapped onto both sides of the drinking spout 31, further preventing water from spilling and ensuring cleanliness and hygiene during use.
