Description

Technical Field

[0001] The present invention relates to the technical field of improving attention, and in particular to a palm-sized treasure. Background Art

[0002] In the current social environment, distraction has become a common cognitive disorder, significantly affecting learning efficiency, work quality and mental health. For example, it significantly reduces efficiency, increases error rate, and weakens creativity; affects learning outcomes and memory conversion, leading to difficulties in retaining information; causes anxiety, frustration and other psychological pressures; damages interpersonal relationships, reduces empathy, etc.

[0003] To improve distraction, more and more people are using concentration training such as meditation to improve awareness and inner peace. However, beginners are easily distracted and cannot maintain their attention for a long time to maintain the training state. In addition, existing concentration training auxiliary equipment also has significant shortcomings, as follows: (1) Smart bracelets / watches: only provide basic heart rate or movement monitoring, lacking special algorithms and intervention logic for distraction; (2) Meditation apps: rely on visual / auditory interaction, which may increase cognitive load and cannot be effective in non-electronic device usage scenarios (such as paper reading); (3) Neurofeedback head-mounted devices: bulky, uncomfortable to wear, and need to be used with a fixed terminal, with poor portability and user compliance.

[0004] Therefore, there is an urgent need for a portable, active, low-intervention threshold concentration enhancement device that can instantly block the interference chain and rebuild the state of concentration through the guidance of tactile, audio-visual feedback, so as to fill the technological gap in the field of portable concentration enhancement tools and provide a breakthrough path for solving systemic cognitive disorders.

DETAILED DESCRIPTION

[0025] In order to deepen the understanding and recognition of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described and introduced in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments, and are not intended to limit the present embodiments in any form. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-19 The present invention provides a technical solution: a palm-sized treasure, comprising an upper cover 1 and a lower cover 2 connected to each other, and a circuit board 3, a battery 4, a charging component, a button component, a lighting component and a driving component installed inside the lower cover 2, which are specifically described as follows.

[0027] Among them, such as Figure 2 、 Figure 3 As shown, the driving component includes a motor 5, a rotating mechanism, a pressure control mechanism and a touch head 7, and the battery 4, charging component, button component, lighting component and motor 5 are all electrically connected to the circuit board 3, and the start, stop, forward and reverse rotation and speed of the motor 5 are controlled by the button component.

[0028] like Figures 2 to 4 As shown, the lower cover 2 is cylindrical, with a base plate 21 installed inside it, and the base plate 21 divides the interior of the lower cover 2 into an upper accommodating chamber 22 and a lower rotating chamber 23, and a sliding groove 10 is provided in the middle of the base plate 21; the circuit board 3, battery 4, charging assembly, button assembly, lighting assembly and motor 5 are installed in the accommodating chamber 22, and the battery 4 is located below the circuit board 3, and the motor 5 is located below the battery 4; the rotating mechanism and touch head 7 are installed in the rotating chamber 23.

[0029] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 12 As shown, the rotating mechanism includes a rotating arm 6, and a mounting through hole 211 is opened in the center of the base plate 21; the power output end of the motor 5 is provided with a motor shaft 51, and the lower end of the motor shaft 51 is provided with an extension rod 53, the extension rod 53 is sleeve-shaped and is sleeved on one end of the motor shaft 51, and is connected to the motor shaft 51 through a first spring 52. The extension rod 53 passes downward through the mounting through hole 211 and is adjustably connected to the rotating arm 6; the touch head 7 is installed at one end of the rotating arm 6; the rotating arm 6 can adjust the rotation radius along its own length direction, and can rotate around the motor 5 shaft as the center.

[0030] In some embodiments, as Figure 3As shown, in order to adjust the position and rotation radius of the rotating arm 6, the rotating mechanism further includes a slider 8; Figure 13 、 Figure 14 As shown, the top surface of the rotating arm 6 is provided with a slide groove 61 along its length direction, and the bottom surface of the slide groove 61 is provided with a plurality of slots 62 distributed at equal intervals. Figure 15 As shown, two rectangular holes 81 are provided at both ends of the slider 8, and a spring piece 82 is provided in each rectangular hole 81, and the bottom surface of the spring piece 82 is provided with a downwardly protruding engaging tooth. Figure 13 As shown, the slider 8 is engaged in the slide groove 61, and the extension rod 53 passes downward through the mounting through hole 211 and connects to the center of the slider 8, thereby connecting to the rotating arm 6; the rotating arm 6 can move horizontally along the slider 8 through the slide groove 61, thereby changing the rotation radius of the rotating arm 6, and the engaging teeth of the two spring pieces 82 can be inserted into the corresponding slots 62, thereby locking the rotation radius of the rotating arm 6.

[0031] In a specific implementation, since the slider 8 is fixedly connected to the extension rod 53, the rotating arm 6 is connected to the slider 8 via the slot 61, allowing the rotating arm 6 to slide through the slot 61. Moreover, the spring 82 is made of plastic. When the rotation radius of the rotating arm 6 needs to be adjusted, the rotating arm 6 is pulled, and the spring 82 contracts under the action of an external force, and the two engaging teeth leave the corresponding slots 62, allowing the rotating arm 6 to slide along the slider 8 through the slot 61, thereby changing the rotation center and rotation radius of the rotating arm 6. When the rotating arm 6 is pulled to the desired position, the two engaging teeth insert into the corresponding slots 62, thereby fixing the rotation center and rotation radius of the rotating arm 6.

[0032] The rotation center of the rotating arm 6 is adjustable, thereby varying the rotation radius to achieve touch control at different locations on the palm. In addition to the above technical solutions, other technical means can also be employed to achieve the technical effect. In other embodiments, the rotating mechanism further comprises an insert and a rubber block; the rotating arm 6 is provided with insertion holes uniformly disposed along its length; an insert is mounted at the bottom end of the extension rod 53, connected to the rubber block, and the rubber block can be inserted into different insertion holes, thereby varying the rotation center and rotation radius of the rotating arm 6.

[0033] In practice, the side of the rotating arm 6 closest to the motor 5 has insertion holes, evenly spaced along its length. An insert block and a rubber block connect the insert block to the end of the motor 5's shaft near the arm 6. The motor 5 shaft is inserted into the rotating arm 6 through the insertion holes and clamped in place by the deformation of the rubber block. To change the rotation radius, the rotating arm 6 is removed from the rubber block by external force, and the motor 5 shaft end is then inserted into the corresponding insertion hole according to the desired radius.

[0034] It should be noted that the key technical points of the embodiment of the present invention are: the pressure control mechanism includes a moving plate 101, a telescopic block 102, a top pressure electric push rod 103, a second spring 104, a control member 105, a positioning member 106, a third spring 107 and an extrusion protrusion 108, the motor shaft 51 is a columnar structure with a large diameter at the upper end and a small diameter at the lower end, and a first spring 52 is provided at the upper end of the extension rod 53 and the side wall step of the motor shaft 51, which is convenient for installing the extension rod 53 and the first spring 52, and the extension rod 53 is sleeved on one end of the motor shaft 51, and the extension rod 53 can slide along the motor shaft 51. When the extension rod 53 moves upward along the motor shaft 51, the extension rod 53 can compress the first spring 52 to store force, so that the first spring 52 can drive the extension rod 53 to reset. A guide ring 54 is fixedly connected to the middle of the extension rod 53, and the lower surface of the guide ring 54 is a conical surface. When the movable plate 101 is pushed by the power output end of the top push rod 103 so that the end of the movable plate 101 approaches the extension rod 53 and moves toward the extension rod 53, the movable plate 101 can squeeze the lower side wall of the guide ring 51 by squeezing the protrusion 108, thereby lifting the guide ring 51 and the extension rod 53, and the movable plate 101 is arranged in the accommodating cavity 22. Two inverted L-shaped limit plates 110 are fixedly connected to the bottom plate 21. The movable plate 101 is a T-shaped structure. The movable plate 101 is inserted between the two limit plates 110 to limit the movable plate 101 and guide the movement of the limit plate 101. The movable plate 101 and the sliding groove 10 overlap with each other. The end of the movable plate 101 away from the motor shaft 51 is welded with a second spring 104. The second spring 104 is welded and fixed to the inner wall of the lower cover 2. When the movable plate 101 is pushed, the second spring 104 will be stretched and stored. Figure 19 As shown, the end surface of the movable plate 101 close to the bottom plate 21 is provided with a movable groove 109, and the movable groove 109 overlaps with the sliding groove 10, and the movable groove 109 is a T-shaped structure. The upper half of the control member 105 is a block structure. The upper half of the control member 105 is slidably connected to the inner side wall of the movable groove 109. The movable groove 109 can limit the control member 105 so that the control member 105 can move horizontally along the movable groove 109. The upper half of the control member 105 is a T-shaped plate, and the lower half of the control member 105, that is, one end of the T-shaped plate, passes through the sliding groove 10, which is convenient for the operator to manipulate the control member 105 by hand. When in use, the operator can grab one end of the T-shaped plate of the control member 105, thereby driving the control member 105 to move in the movable groove 109. The upper end surface of the control member 105 is provided with a plug hole. A positioning member 106 is inserted into the plug hole, and the upper half of the positioning member 106 can slide up and down in the plug hole. The upper half of the positioning member 106 is a cam-shaped structure. Figure 19As shown, the upper half of the positioning member 106 is a columnar structure, which enables the upper half of the positioning member 106 to slide in the control member 105, thereby changing the height of the positioning member 106. A third spring 107 is provided between the positioning member 106 and the control member 105. When one end of the T-shaped plate of the control member 105 is pushed by hand, the positioning member 106 will move with the control member 105. When the cam-shaped structure of the upper half of the positioning member 106 squeezes the telescopic block 102, the positioning member 106 also bears a reaction force, and the upper half of the positioning member 106 moves in the plug hole due to the reaction force. At this time, the upper half of the positioning member 106 can compress the third spring 107, so that the positioning member 106 can be moved more easily to the bottom of the telescopic block 102. When the positioning member 106 is located below the telescopic block 102, the third spring 107 can reset the positioning member 106, thereby pushing the telescopic block 102 out. At least two telescopic grooves with T-shaped structures are provided in the middle of the movable plate 101. , a T-shaped telescopic block 102 is inserted into the telescopic slot and the lower end of the telescopic block 102 is located at the moving slot 109. A top pressure electric push rod 103 is fixedly connected to the inner wall of the lower cover 2, and the top pressure electric push rod 103 is electrically connected to the circuit board 3. Due to the limitation of the telescopic slot, the telescopic block 102 can only move along the vertical direction of the movable plate 101. When the telescopic blocks 102 at different positions are ejected by the positioning members 106, the ejected telescopic blocks 102 are limited and fixed, and the ejected telescopic blocks 102 enter the motion stroke of the power output end of the top pressure push rod 103. Because the motion stroke distance of the power output end of the top pressure push rod 103 is fixed, when the power of the top pressure push rod 103 is When the output end contacts the telescopic block 102 at different positions, the top pressure push rod 103 can move the telescopic block 102. Because the telescopic block 102 is fixed to the movable plate 101, the telescopic block 102 can push the movable plate 101 to move different distances. An extrusion protrusion 108 is provided at one end of the movable plate 101. During specific implementation, the user changes the pressure of the touch head on the palm according to needs. When changing the applied pressure, the user first moves the control member 105 along the sliding groove 10 by hand. At the same time, the control member 105 will move in the moving groove 109. When moving, the control member 105 can squeeze the telescopic block 102 through the positioning member 106, and the different positions can be adjusted according to the needs of the user. The telescopic block 102 is pushed up. At this time, the pushed-out telescopic block 102 enters the motion stroke of the power output end of the pressing push rod 103. Therefore, the pressing push rod 103 can also push the movable plate 101 toward the extension rod 53 when pushing the telescopic block 102. During the movement of the movable plate 101, the squeezing protrusion 108 will abut against the inclined surface of the guide ring 51. When the movable plate 101 moves, it can squeeze the guide ring 54 through the squeezing protrusion 108. As the squeezing protrusion 108 gradually approaches the extension rod 53, the guide ring 54 and the extension rod 53 are pushed up together. During the upward movement of the extension rod 53, the first spring 52 can be compressed and stored.The movable plate 101 can stretch and store the second spring 104 during the movement. When the push-pull electric push rod 103 retracts, the movable plate 101 is reset under the action of the second spring 104. At this time, the guide ring 54 loses the squeezing force, and the extension rod 53 is reset under the action of the first spring 52, and drives the rotating arm 6 and the touch head 7 to move downward, so that the pressure of the touch head 7 on the user's palm becomes greater; in this way, the change in pressure makes the user's palm feel different, thereby improving the user's concentration. By changing the position of the control member 105, the telescopic blocks 102 at different positions are lifted, thereby changing the position of the movable plate 10 The distance 1 moves and the distance the extension rod 53 rises are used to control the pressure change of the touch head 7 to adapt to the usage habits of different people. When setting the second spring 104, a spring with a larger elastic coefficient can be selected. In this way, when the control member 105 squeezes the telescopic block 102, the squeezing force will not cause the second spring 104 to deform, thereby avoiding causing the moving plate 101 to move. Even if the moving plate 101 moves during this process, because the travel distance of the moving plate 101 is limited, when the moving plate 101 moves to the maximum moving distance and cannot move further, the control member 105 is used to lift the telescopic block 102.

[0035] In some embodiments, the ability to vary the hardness and softness of the touch head 7 at the end of the rotating arm 6 can further enhance the present invention's ability to improve concentration. Specifically, the touch head 7 can be two-ended, with one end made of a hard material and the other of a soft material; or, the touch head 7 can be spherical, with one half made of a hard material and the other half made of a soft material.

[0036] In practice, the touch head 7 is configured as a two-ended device, with one end being a hard head, such as plastic, and the other being a soft head, such as soft rubber. These two heads are positioned at either end of the rotating arm 6 and threadedly connected to the threaded holes 63 on the rotating arm 6. To adjust the hardness or softness of the touch head 7, simply remove the touch head 7 and reorient it. Alternatively, the touch head 7 can be spherical, with a bearing embedded in the rotating arm 6 to connect it to the spherical touch head 7. Half of the spherical touch head 7 is made of a hard material, while the other half is made of a soft material. This allows the hardness or softness of the palm touch to be varied by rotating the spherical surface.

[0037] In other embodiments, Figure 16 As shown, the touch head 7 includes a touch end 71 and a connection end 72 connected to each other, and the connection end 72 is provided with an external thread; one end of the rotating arm 6 is provided with a threaded hole 63, and the connection end 72 of the touch head 7 is connected to the threaded hole 63 of the rotating arm 6 through a thread.

[0038] In some embodiments, as Figure 4 、 Figure 7As shown, the charging assembly includes a charging fixed groove 24 provided on the outer wall of the accommodating cavity 22, and two charging springs 25 installed in the charging fixed groove 24; the charging fixed groove 24 has two charging ports 241. Figure 6 、 Figure 7 As shown, the bottom of the charging spring clip 25 is provided with a horizontal U-shaped bend 251 protruding to one side, and the top is provided with an L-shaped bend 252 protruding to the other side; and the horizontal U-shaped bends 251 of the two charging spring clips 25 are respectively inserted outward from the inside of the accommodating cavity 22 into the corresponding charging port 241, and the L-shaped bends 252 of the two charging spring clips 25 are respectively electrically connected to the circuit board 3.

[0039] When implementing it specifically, Figure 9 As shown, the circuit board 3 has two spring connection slots 31. The L-shaped bends 252 of the two charging springs 25 are inserted into the corresponding spring connection slots 31 and connected to the circuit board 3 by welding. The present invention can charge the battery 4 through the charging port 241 to drive other components to work, and can also store electrical energy in the battery 4 for use as a power bank.

[0040] In other embodiments, Figure 3 As shown, the charging assembly also includes a magnetic iron sheet 26 installed in the charging fixed slot 24. Figure 4 、 Figure 5 As shown, the charging fixing slot 24 is further provided with two side positioning slots 242 located on both sides of the two charging ports 241, and a lower positioning slot 243 located below the two charging ports 241, and both the side positioning slots 242 and the lower positioning slot 243 are recessed into the accommodating cavity 22. Figure 1 、 Figure 8 As shown, the magnetic sheet 26 includes two reserved holes 261, two side through holes 262 located on both sides of the two reserved holes 261, and a lower through hole 263 located below the two reserved holes 261; and the outer ends of the two charging ports 241 pass through the corresponding reserved holes 261 and extend outward, the outer ends of the two side positioning grooves 242 pass through the corresponding side through holes 262 and extend outward, and the lower positioning groove 243 passes through the lower through hole 263 and extends outward.

[0041] During specific implementation, the magnetic sheet 26 is fixedly connected to the charging fixed slot 24 by means of rubber coating, and the two reserved holes 261, two side through holes 262, and one lower through hole 263 on the magnetic sheet 26 are respectively matched with the two charging ports 241, two side positioning grooves 242, and one lower positioning groove 243 on the charging fixed slot 24, so as to facilitate the charger of the present invention to be inserted into the two side positioning grooves 242 and one lower positioning groove 243 for positioning and installation.

[0042] Specifically, the charger in this embodiment of the present invention features two charging pins, two side inserts located on either side, and a lower insert located below. The two side inserts mate with the two side positioning slots 242, while the lower insert mates with the lower positioning slot 243. During charging, the two side inserts and the lower insert are inserted into the two side positioning slots 242 and the lower positioning slot 243, respectively, and the magnetic sheet 26 magnetically attracts the charger, thereby enhancing its stability.

[0043] In some embodiments, as Figure 4 、 Figure 5 As shown, a plurality of buckles 221 and a plurality of reinforcing ribs 222 are installed on the inner wall of the accommodating cavity 22; Figure 10 As shown, the edge of the circuit board 3 is placed on a plurality of reinforcing ribs 222 and is engaged in a plurality of buckles 221 .

[0044] When implementing it specifically, Figure 10 、 Figure 15 As shown, several clips 221 engage the edges of the circuit board 3, limiting its position and securing it to the battery 4. By limiting the position of the circuit board 3, the battery 4 is pressed between the circuit board 3 and the motor 5, forming a clamping fixation. Several reinforcing ribs 222 provide side limits and support for the circuit board 3, preventing it from shaking and increasing the stability of the structure.

[0045] In some embodiments, as Figure 9 As shown, the lighting assembly includes several low beam lights 91 and several warning lights 92 installed on the top surface of the circuit board 3, and the button assembly is used to control the lighting and extinguishing of the low beam lights 91 and the flashing frequency and lighting and extinguishing of the warning lights 92.

[0046] In specific implementation, several warning lights 92 are evenly arranged in a straight line. Each warning light 92 features three warning colors and is controlled by a button assembly to adjust the flashing frequency or constant on state of the warning lights 92. Several low-beam lights 91 are located on either side of the warning lights 92 and are also controlled by the button assembly to adjust the low-beam lights 91 on and off. Furthermore, the button assembly controls the flashing frequency and on / off of the warning lights 92, the on / off of the low-beam lights 91, the start / stop, forward / reverse rotation, speed control of the motor 5, and other functions such as timing. For example, the lights can be combined with the rotating arm 6 to create a timer effect. When the rotating arm 6 rotates for half an hour, a light illuminates as a reminder, and the button assembly controls the on / off function.

[0047] In some embodiments, as Figure 5 、 Figure 9 、 Figure 10 、 Figure 11As shown, the button assembly includes several buttons located in the accommodating cavity 22, several button slots 223 opened on the side walls of the accommodating cavity 22, several limiting protrusions 212 installed on the top surface of the bottom plate 21, several travel slots 32 opened on the edge of the circuit board 3, and a switch 33 installed in each travel slot 32. The positions of the travel slots 32 and the button slots 223 match, and the number of buttons, switches 33, travel slots 32 and button slots 223 match. Figure 3 、 Figure 11 As shown, the button includes a pressing portion 34 and a T-shaped travel portion 35; the top of each travel portion 35 is located in the corresponding travel groove 32, the bottom is located between the corresponding limiting protrusion 212 and the inner wall of the accommodating cavity 22, and a contact 351 is provided on the outer side; each pressing portion 34 is inserted into the corresponding button slot hole 223 and is located on the outer side of the corresponding travel portion 35 contact 351.

[0048] In practice, the button's pressing portion 34 is made of rubber and secured to the button slot 223 via rubber encapsulation. The pressing portion 34 and the travel portion 35 are separate, rather than fixedly connected. The top of the travel portion 35 is held in place by the travel slot 32. When the pressing portion 34 is pressed, it compresses the contact 351 of the corresponding travel portion 35, pushing the travel portion 35 toward the corresponding travel slot 32, thereby contacting the switch 33 in the travel slot 32 and depressing the switch 33 to activate the button function. When the pressing portion 34 is released, it resets due to the properties of the rubber material.

[0049] Furthermore, the number of buttons is at least one, preferably three. For example, the three buttons in the accompanying drawings are used: the left button is used to control the on and off of the low beam 91, the middle button is used to control the start and stop of the motor 5, and the right button is used to control the start and stop of the warning light 92; alternatively, the left button is used to control the illumination intensity of the low beam 91, the middle button is used to control the speed of the motor 5, and a long press can adjust the forward and reverse rotation of the motor 5, and the right button is used to control the flashing frequency and constant brightness of the warning light 92.

[0050] Let's take a button as an example: a long press is used to switch mode selection. For example, long pressing the button enters mode selection, and the control mode is selected based on the number or color of the illuminated warning lights 92. Specifically, first, long press the button, and the warning lights 92 will all illuminate as a reminder to enter mode selection. Then, press the button once, and the low beam headlights 91 will illuminate red, indicating that the motor 5 mode has been entered. After a delay of several seconds, the low beam headlights 91 will lock. At this point, the control mode of the motor 5 is entered, and only the motor 5 can be controlled. For example, pressing the button starts the motor 5 in forward rotation, pressing the button twice in succession adjusts the speed of the motor 5, pressing the button three times in succession causes the motor 5 to reverse, and pressing the button four times in succession stops the motor 5. Long pressing the button again re-enters the mode selection, and based on the number and color of the illuminated lights, the mode of the warning lights 92 or the low beam headlights 91 will be entered.

[0051] In other embodiments, Figure 9 、 Figure 10 As shown, a plurality of support grooves 36 are further provided on the edge of the circuit board 3 . Each support groove 36 is located between two adjacent travel grooves 32 and is supported by the top of the corresponding reinforcing rib 222 .

[0052] In a specific implementation, the installation area of ​​the button assembly is supported by the reinforcing ribs 222, which can improve the stability of the pressing.

[0053] In some embodiments, as Figure 12 As shown, two lugs are provided on both sides of the motor 5, each lug has a connecting hole, and a bolt is installed in the connecting hole. Figure 5 As shown, two connecting parts 213 are installed on the top surface of the bottom plate 21. Each connecting part 213 is cylindrical and has a thread on its inner wall. The bolt passes through the corresponding connecting hole and is connected to the corresponding connecting part 213 through a thread.

[0054] In some embodiments, as Figure 9 As shown, two battery connection slots 37 are provided on the circuit board 3 , and two battery connection pieces 41 are installed on the battery 4 and are respectively inserted into the corresponding battery connection slots 37 .

[0055] In a specific implementation, the circuit board 3 and the battery 4 are bonded by an adhesive (the adhesive is 3m adhesive), and the circuit board 3 and the battery 4 are electrically connected via two battery connecting pieces 41 , thereby supplying power to the battery 4 .

[0056] In some embodiments, as Figure 1 、 Figure 17 As shown, the upper cover 1 is provided with a plurality of transparent rectangular frames 11 and a plurality of lenses 12; the transparent rectangular frames 11 match the size and number of the warning lights 92; the lenses 12 are in an upwardly protruding semicircular shape, and the lenses 12 match the size and number of the low beam lights 91.

[0057] In practice, the transparent rectangular frame 11 allows the light from the warning light 92 to radiate outward without being blocked by the upper cover 1. The lens 12 acts as a lampshade for the low-beam headlight 91. Because the lens 12 is an upwardly convex semicircular shape with a downwardly concave edge, it does not block the light that passes through the bottom of the lens 12. If the lens 12 were flat, its base would be too thick, partially blocking the low-beam headlight 91 light. Furthermore, the rectangular frame 11 and lens 12 are made of the same plastic material as the upper cover 1.

[0058] In other embodiments, Figure 17 As shown, the bottom surface of the upper cover 1 is provided with a recessed honeycomb structure 13 for softening the light and guiding the light in a directional manner, while making the structure stable and reducing the weight of the upper cover 1 .

[0059] In some embodiments, the upper cover 1 and the lower cover 2 are fixedly connected in an irremovable manner by ultrasonic welding.

[0060] In some embodiments, as Figure 3 As shown, a rubber ring 27 is installed on the bottom edge of the lower cover 2.

[0061] In specific implementation, since one end of the rotating cavity 23 is facing the palm of the human body during use, the rubber ring 27 is provided at the edge of the lower cover 2 to prevent the edge of the lower cover 2 from directly contacting the palm and to improve the touch feel through the rubber ring 27.

[0062] In other embodiments, since excessive noise should not be generated during the rotation of the motor 5 to avoid affecting the user's attention, the present invention can be processed to reduce noise. Specifically, sound-absorbing cotton is provided on the inner bottom surface of the lower cover 2, and other means can also be used to achieve this.

[0063] In summary, by holding the present invention in the palm of the user's hand, the rotation state of the rotating arm 6 can be changed through timing, timekeeping, forward and reverse rotation, and speed control, thereby improving personal concentration by stimulating the palm through the touch head 7. Especially when the user is distracted or distracted, the present invention can bring back thoughts through the stimulation of the palm, thereby entering a state of concentration. The rotation radius of the rotating arm 6 can be adjusted to touch different positions of the palm, so that the force position of the palm changes, thereby focusing the user's attention and thoughts on the hand, achieving a concentration effect, especially in meditation. In addition, the present invention also has the effects of a low beam 91 and a warning light 92, which can provide light in a dark environment, and can be used as a power bank through the charging component. It not only has low power and energy consumption, but also is easy to carry.

[0064] Although the embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the use of the embodiments of the present invention and is not intended to limit the present invention in any way. Those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
