Abstract
Description
Technical Field
[0001] This utility model relates to the field of brainwave detection technology, and more specifically, to a conveniently wearable brainwave detection device. Background Technology
[0002] Brainwave analyzers record the brain's electrical activity and generate an electroencephalogram (EEG). By analyzing the characteristics and patterns of the EEG, doctors can diagnose various brain diseases, such as epilepsy, brain injury, and cerebrovascular diseases. Abnormal EEG patterns provide doctors with important diagnostic clues.
[0003] However, in traditional EEG monitors, due to the different head sizes of users, some people are a perfect fit, while others cannot meet the requirements for wearing them. If buckles and straps are used for fixation, the fixation method is also quite troublesome, making it extremely inconvenient for users to wear and difficult to disassemble. In order to address the above problems, a convenient EEG monitor is proposed. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a convenient-to-wear brainwave detector, which has the advantages of being easy to wear and remove, and suitable for most people's head shapes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient-to-wear brainwave detector, including a wearing band, the wearing band having a groove inside, a rotating shaft rotatably connected inside the groove, a plastic strip fixedly connected to the surface of the rotating shaft, a first toothed groove on the left side surface of the front part of the plastic strip, a second toothed groove on the right side surface of the rear part of the plastic strip, and an adjustment structure provided on the surface of the plastic strip.
[0006] As a preferred technical solution of this utility model: a fixed hoop is fixedly connected to the upper surface of the wearing hoop, and a movable groove is opened inside the fixed hoop, and several detection structures are movably connected inside the movable groove.
[0007] As a preferred technical solution of this utility model: the adjustment structure includes a fixed shell movably connected to the surface of the plastic belt, a rotating shaft two is rotatably connected inside the fixed shell, a knob is fixedly connected to the upper surface of the rotating shaft two, a long gear is fixedly connected to the lower surface of the rotating shaft two, the long gear meshes with the first tooth groove, and the long gear meshes with the second tooth groove.
[0008] As a preferred technical solution of this utility model: a soft rubber ring is fixedly connected to the inner surface of the wearing band, and the soft rubber ring is located on the upper and lower sides of the plastic band.
[0009] As a preferred technical solution of this utility model: the detection structure includes a movable block movably connected inside the movable slot, a fixed column is fixedly connected inside the movable block, and a brainwave detection chip is fixedly connected to one side surface of the fixed column.
[0010] As a preferred technical solution of this utility model: the surface of the wearing band is provided with heat dissipation holes, which are located between the upper and lower soft rubber rings.
[0011] As a preferred technical solution of this utility model: the lower edge of the wearing hoop and the upper edge of the fixing hoop are both provided with rounded corners, and the arc values of the upper and lower rounded corners are equal.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model drives the second rotating shaft inside the fixed shell to rotate by rotating the knob. The surface of the second rotating shaft and the inside of the fixed shell have damping force. As the long gear meshes with the first and second tooth grooves at the same time, the front and rear plastic belts move closer together at the same speed, so that the wearing hoop is fixed on the head of the person being tested. This device can quickly fix the brainwave detector by rotating the knob. It is convenient to wear and remove and is suitable for most head shapes.
[0013] 2. This utility model allows the fixed column to slide inside the movable groove by manually moving the movable block. Because multiple sets of brainwave detection chips are installed inside the movable groove, and because the positions of the brainwave detection chips are set, the brainwave detection chips make contact with the scalp of the person being tested at multiple points, thus satisfying the requirements of the brainwave detector to detect the person's brainwaves. This device adopts the mobility of the detection points, thereby making the brainwave data acquisition more complete and the practicality of the brainwave detector stronger.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 5 As shown, this utility model provides a convenient-to-wear brainwave detector, including a wearing hoop 1, a groove 2 inside the wearing hoop 1, a rotating shaft 3 rotatably connected inside the groove 2, a plastic strip 4 fixedly connected to the surface of the rotating shaft 3, a first toothed groove 5 on the left side surface of the front plastic strip 4, a second toothed groove 6 on the right side surface of the rear plastic strip 4, and an adjustment structure on the surface of the plastic strip 4.
[0018] When brainwave testing is required, the staff moves the headband 1 down from the wearer's head and rotates the knob 11. The rotation of the knob 11 causes the rotating shaft 10 to rotate inside the fixed shell 9, which in turn causes the long gear 12 to mesh with the first tooth groove 5 and the second tooth groove 6. This causes the plastic band 4 to move away from the inside of the groove 2, while the rotating shaft 3 rotates inside the groove 2. This causes the two plastic bands 4 to move closer to each other, so that the brainwave detector is worn on the user's head.
[0019] Among them, the upper surface of the wearing hoop 1 is fixedly connected to the fixing hoop 7, the inside of the fixing hoop 7 is provided with the movable groove 8, and the inside of the movable groove 8 is movably connected to several detection structures.
[0020] Staff members manually move the fixed column 15 to move the movable block 14 inside the movable slot 8. The position of the movable block 14 is adjusted before wearing the device. The brainwave detection chip 16 is in contact with the scalp of the person being tested. Since there are multiple sets of brainwave detection chips 16 inside the movable slot 8, samples are taken from different points on the head of the person being tested, thereby collecting brainwave data.
[0021] The adjustment structure includes a fixed shell 9 movably connected to the surface of the plastic belt 4. A rotating shaft 10 is rotatably connected inside the fixed shell 9. A knob 11 is fixedly connected to the upper surface of the rotating shaft 10. A long gear 12 is fixedly connected to the lower surface of the rotating shaft 10. The long gear 12 meshes with the first tooth groove 5 and with the second tooth groove 6.
[0022] By rotating the knob 11, the second shaft 10 is driven to rotate inside the fixed shell 9, and the plastic belt 4 is adjusted because the long gear 12 meshes with the first tooth groove 5 and the second tooth groove 6.
[0023] Among them, a soft rubber ring 13 is fixedly connected to the inner surface of the wearing hoop 1, and the soft rubber ring 13 is located on the upper and lower sides of the plastic belt 4.
[0024] The design of the soft rubber ring 13 prevents excessive contact between the inside of the wearing band 1 and the scalp of the person being tested, thus avoiding the phenomenon of stuffiness and sweating.
[0025] The detection structure includes a movable block 14 movably connected inside the movable slot 8, a fixed column 15 fixedly connected inside the movable block 14, and a brainwave detection chip 16 fixedly connected to one side surface of the fixed column 15.
[0026] By moving the fixed column 15, the movable block 14 is moved inside the displacement groove 8, thereby enabling the brainwave detection chip 16 to perform brainwave detection on different points on the head.
[0027] Among them, the surface of the wearing hoop 1 is provided with heat dissipation holes 17, which are located between the upper and lower soft rubber rings 13.
[0028] The design of the heat dissipation holes 17 avoids the inner wall of the wearing band 1 from coming into contact with the scalp of the person being tested and prevents the phenomenon of sweating caused by wearing it for a long time.
[0029] The lower edge of the wearing hoop 1 and the upper edge of the fixing hoop 7 are both provided with rounded corners 18, and the arc values of the upper and lower rounded corners 18 are equal.
[0030] The 18-rounded corner design prevents abrasion between the scalp of the person being tested and the brainwave detection device, thus avoiding injury to the person being tested.
[0031] Working principle and usage process of this utility model: When brainwave testing is required, the staff moves the headband 1 down from the wearer's head and rotates the knob 11. The rotation of the knob 11 causes the rotating shaft 10 to rotate inside the fixed shell 9, thereby causing the long gear 12 to mesh with the first tooth groove 5 and the second tooth groove 6. This causes the plastic band 4 to move away from the inside of the groove 2, while the rotating shaft 3 rotates inside the groove 2. This causes the two plastic bands 4 to move closer to each other, so that the brainwave detector is worn on the user's head.
[0032] Staff members manually move the fixed column 15 to move the movable block 14 inside the movable slot 8. The position of the movable block 14 is adjusted before wearing the device. The brainwave detection chip 16 is in contact with the scalp of the person being tested. Since there are multiple sets of brainwave detection chips 16 inside the movable slot 8, samples are taken from different points on the head of the person being tested, thereby collecting brainwave data.
[0033] By rotating the knob 11, the second shaft 10 is driven to rotate inside the fixed shell 9, and the plastic belt 4 is adjusted because the long gear 12 meshes with the first tooth groove 5 and the second tooth groove 6.
[0034] The design of the soft rubber ring 13 prevents excessive contact between the inside of the wearing band 1 and the scalp of the person being tested, thus avoiding the phenomenon of stuffiness and sweating.
[0035] By moving the fixed column 15, the movable block 14 is moved inside the displacement groove 8, thereby enabling the brainwave detection chip 16 to perform brainwave detection on different points on the head.
[0036] The design of the heat dissipation holes 17 avoids the inner wall of the wearing band 1 from coming into contact with the scalp of the person being tested and prevents the phenomenon of sweating caused by wearing it for a long time.
[0037] The 18-rounded corner design prevents abrasion between the scalp of the person being tested and the brainwave detection device, thus avoiding injury to the person being tested.
