Description

Technical Field

[0001] The present invention relates to the technical field of blind readers, in particular to a multifunctional blind reading aid. Background Art

[0002] A reading aid for the blind is an electrically operated tool used by the blind during reading training and text reading. Different from traditional paper Braille reading tools, this type of electrically operated reading device can realize the reading of e-books, reduce the use and consumption of paper, and is easy to carry. It can use a single reading device to realize the reading and learning of diversified electronic digital information, making it easier for blind users to interact with digital information stably when they have visual impairments.

[0003] Existing reading aids for the blind generally use the lifting and lowering of a tactile element to change the display of Braille text on the reader, allowing the blind user to feel the corresponding lifting and lowering of the tactile element according to the different electronic digital information and text being read, thereby achieving a reading effect. However, due to differences in user behavior and physical conditions, a single reading aid is not effective, is easily dirty and damaged, and is difficult to clean, as shown below:

[0004] When blind users use the device for a long time or sweat a lot, their fingers need to repeatedly touch the tactile elements that make up Braille when reading. During this process, as the reading time accumulates, hand sweat, dirt and dust on the hands will continue to adhere to the tactile elements in large quantities. Due to the special properties of sweat, this not only affects the reading experience of blind users, but also causes corrosion and material damage to the tactile elements due to sweat, affecting the stability and sensitivity of the reading aid, and also affecting the safety of hand contact during subsequent use.

[0005] In response to the above problems, it is urgent to carry out innovative design based on the original blind reading aids. Summary of the Invention

[0006] The purpose of the present invention is to provide a multifunctional reading aid for the blind to solve the problem of the existing reading aid for the blind proposed in the above background technology, which is prone to dirt, corrosion and material damage after long-term use, affecting the stability and sensitivity of the reading aid, and also affecting the safety of hand contact during subsequent use.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a multifunctional reading aid for the blind, comprising:

[0008] The reader body is equipped with a digital display, electric control buttons, and a trigger rod. The trigger rod rises and falls synchronously according to the Braille displayed on the digital display. An air guide component is provided on the front side of the reader body next to the trigger rod. The air guide component is used to drive and control the airflow in the area where the trigger rod is located.

[0009] It further includes: a cleaning component, which is arranged on the side of the trigger rod on the reader body. An electromagnet is installed in the reader body directly below the trigger rod. A sunken cavity is formed on the reader body in the area where the trigger rod is located. A cleaning and processing system for the trigger rod is arranged in the sunken cavity and on the reader body on the left and right sides.

[0010] Preferably, the air outlet of the air guiding component is arranged slightly above the middle section of the sunken cavity, and an electric control valve is also arranged at the position of the air outlet of the air guiding component. The air guiding component and the electric control valve are controlled by a controller on the reader body.

[0011] Preferably, the cleaning component includes a motor screw rod component and a cleaning brush. The cleaning brush is threadedly connected to the motor screw rod component. The length of the cleaning brush is equal to the width of the sunken cavity, and the motor screw rod component is distributed parallel to the long side of the sunken cavity.

[0012] Preferably, a storage cavity is further formed on the reader body between the liquid discharge port and the sunken cavity. The storage cavity is used for storing the cleaning brush, and the bottom of the storage cavity is communicated with the liquid discharge port and the sunken cavity.

[0013] Preferably, the cleaning and processing system for the trigger rod includes liquid discharge ports on the left and right sides of the sunken cavity and a liquid storage cavity body. The liquid storage cavity body is sequentially communicated with the sunken cavity and the liquid discharge port. A valve is arranged at the communication position of the liquid storage cavity body, the sunken cavity and the liquid discharge port;

[0014] Meanwhile, the cleaning and processing system further includes a control switch on the reader body for controlling the start of the valve.

[0015] Preferably, a partition board is installed on the bottom of the sunken cavity through an electric lifter in a lifting and movable manner. The partition board is penetrated by the trigger rod. A sealed liquid bag is arranged in the penetrating setting of the partition board and the trigger rod;

[0016] And an elastic isolation sheet is arranged between the bottom edge of the partition board and the inner wall edge of the bottom of the sunken cavity.

[0017] Preferably, the elastic isolation sheet is used for the sealed isolation treatment of the lower end of the trigger rod and the area where the electromagnet and the electric lifter are located, and a relative lifting structure in which the partition board and the sunken cavity are in fit is formed.

[0018] Preferably, the lower end of the trigger rod is arranged in a magnetic structure, and the trigger rod and the electromagnet are arranged in a one-to-one correspondence and vertically coaxially.

[0019] Preferably, a penetrating relative telescopic structure is formed between the trigger rod and the fixing bracket outside the electromagnet. A sealing ring is also installed at the penetrating position of the fixing bracket outside the electromagnet.

[0020] Preferably, the bottom of the sealed liquid sac extends downward below the lower end surface of the isolation plate, and the sealed liquid sac and the sealing ring are coaxially installed and distributed correspondingly.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The multifunctional blind reading assistor can realize the conversion of electronic data information, enabling blind users to read efficiently. At the same time, it can automatically clean the sweat and sweat stains generated during the reading process under electric operation. The specific content is as follows:

[0022] 1. Only by using the electro-controlled magnet and its integrated circuit, the electronic text information displayed on the digital display is converted into tactile Braille with the change of the tactile rod. The tactile rod is driven by the electro-controlled magnet to rise and fall. When the tactile rod provides Braille output, the air guide component dries the user's hand, improving the comfort of use;

[0023] Further, after the Braille formed by the tactile rods is applied, a large amount of sweat stains adhere to the tactile rods. By controlling the use of the cleaning component through electric operation, the outer surface of the tactile rods can be cleaned under the reciprocating action of the cleaning brush, and the operation is fast;

[0024] 2. A cleaning system composed of a liquid storage cavity, a sinking cavity and a liquid discharge port is also provided. Under electric operation, the valve is controlled to open, and the cleaning liquid inside the liquid storage cavity flows out. The cleaning liquid cleans the tactile rods in the sinking cavity and acts with the cleaning brush to quickly clean the tactile rods. At the same time, the air guide component and the electro-controlled valve can also complete the drying process of the cleaned tactile rods;

[0025] Further, the isolation plate is lifted and moved by the electric lifter. By adjusting the positioning height of the isolation plate, the daily use of the tactile rods is facilitated. At the same time, the outer extension length of the tactile rods can also be changed to effectively clean the residual dirt and sweat stains in the corner positions of the sinking cavity. During this process, the sealing ring and the elastic isolation sheet are used to avoid the problems of liquid leakage and damage to electrical components during the self-cleaning process.

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0038] Embodiment 1: Please refer to Figures 1 - 10 , the present invention provides a technical solution: A multifunctional blind reading assistor, including:

[0039] Reader body 1, on which a digital display 2, an electric control button 3 and a touch rod 4 are installed. The touch rod 4 synchronously rises and falls according to the Braille displayed on the digital display 2, and an air guiding component 5 is arranged on the front side of the reader body 1 beside the touch rod 4. The air guiding component 5 is used for the air flow driving control in the area where the touch rod 4 is located; the lower end of the touch rod 4 is arranged in a magnetic structure, and the touch rod 4 and the electric control magnet 7 are in one-to-one correspondence and vertically coaxially distributed;

[0040] In the above technical solution, various electric control buttons 3 are provided on the reader body 1, an external headphone jack and a speaker are also provided, and various external interfaces are also provided to facilitate information storage in the reader body 1. The digital display 2 can display normal text and Braille. Under the action of integrated circuits and electrical components, the Braille is driven by an electric control magnet 7 to lift the touch rod 4, so that the arranged Braille formed by the touch rod 4 is the same as the Braille information displayed on the digital display 2.

[0041] At the same time, in the solution, the air outlet of the air guide component 5 is arranged slightly above the middle section of the sunken cavity 10, and an electric control valve 501 is also arranged at the position of the air outlet of the air guide component 5. The air guide component 5 and the electric control valve 501 are controlled by the controller on the reader body 1. At the same time, the air guide component 5 can drive the airflow for the drive where the touch rod 4 is used, making the hands of the blind user more comfortable when using the touch rod 4. The air guide component 5 and the electric control valve 501 act synchronously and start at the same time to prevent external dirt or other substances from entering through its air outlet when the air guide component 5 is in a non-use state.

[0042] Another example is Figures 5 - 8 The shown technical solution of the present invention further includes: a cleaning component 6, which is arranged on the side of the touch rod 4 on the reader body 1. An electric control magnet 7 is installed in the reader body 1 directly below the touch rod 4. A sunken cavity 10 is opened on the reader body 1 in the area where the touch rod 4 is located, and a cleaning treatment system for the touch rod 4 is arranged on the sunken cavity 10 and the reader body 1 on the left and right sides; the cleaning component 6 includes a motor screw rod component 601 and a cleaning brush 602. The cleaning brush 602 and the motor screw rod component 601 are connected by a threaded connection. The length of the cleaning brush 602 is equal to the width of the sunken cavity 10, and the motor screw rod component 601 is parallel to the long side of the sunken cavity 10; a storage cavity 603 is further opened on the reader body 1 between the liquid discharge port 9 and the sunken cavity 10. The storage cavity 603 is used for storing the cleaning brush 602, and the bottom of the storage cavity 603 is communicated with the liquid discharge port 9 and the sunken cavity 10;

[0043] In the above technical solution, after the touch rod 4 is used, dirt and impurities will adhere to it. By controlling the use of the cleaning component 6, the motor screw rod component 601 is started to drive the cleaning brush 602 to move back and forth, and the dirt and impurities adhering to the touch rod 4 are cleaned during the movement. At the same time, the setting of the storage cavity 603 can accommodate and temporarily store and drain the cleaning brush 602.

[0044] In the above solution, another example is Figures 6 - 8As shown, the cleaning system for the trigger rod 4 includes drain ports 9 on the left and right sides of the sinking cavity 10 and a liquid storage cavity 8. The liquid storage cavity 8 is sequentially connected to the sinking cavity 10 and the drain port 9. A valve is provided at the connection of the liquid storage cavity 8, the sinking cavity 10, and the drain port 9. At the same time, the cleaning system also includes a control switch on the reader body 1 for controlling the activation of the valve. By controlling the valve, the cleaning solution stored inside the liquid storage cavity 8 is introduced into the sinking cavity 10 and discharged from the drain port 9, achieving the cleaning of the trigger rod 4 inside the sinking cavity 10. It functions the same as the cleaning brush 602 in the above solution, achieving a good cleaning effect.

[0045] At the same time, in this solution, a partition plate 11 is installed at the bottom of the sinking cavity 10 in a lifting and movable manner through an electric lifter 13. The partition plate 11 is penetrated by the trigger rod 4. And an elastic isolation sheet 12 is provided between the bottom edge of the partition plate 11 and the inner wall edge of the bottom of the sinking cavity 10. The elastic isolation sheet 12 is used for the sealing isolation treatment of the lower end of the trigger rod 4 and the area where the electro-magnet 7 and the electric lifter 13 are located. And a relative lifting structure in which the partition plate 11 and the sinking cavity 10 are in contact with each other is formed.

[0046] In the above technical solution, the electric lifter 13 can control the lifting of the partition plate 11. One side of the partition plate 11 can rise in the non-use state, so that the top surface of the partition plate 11 is coplanar with the upper end of the trigger rod 4, preventing the collision damage of the trigger rod 4 in the non-use state. At the same time, when the partition plate 11 descends to the bottom, the trigger rod 4 and the sinking cavity 10 are completely exposed, so that there is no residual dirt in the corners and crevices during cleaning, improving the cleaning effect. The use of the elastic isolation sheet 12 here can prevent the damage of the electrical components below the partition plate 11 caused by the cleaning operation.

[0047] Embodiment 2: On the basis of Embodiment 1, the present invention is also as Figure 9 and Figure 10 shown. There is a sealed liquid sac 1101 in the through-type setting of the partition plate 11 and the trigger rod 4. A through-type relative telescopic structure is formed between the trigger rod 4 and the fixed bracket outside the electro-magnet 7. A sealing ring 1102 is also installed at the penetration of the fixed bracket outside the electro-magnet 7. The bottom of the sealed liquid sac 1101 extends downward on the lower end surface of the partition plate 11, and the sealed liquid sac 1101 and the sealing ring 1102 are arranged in a coaxial and corresponding manner.

[0048] The design of the sealing liquid bag 1101 ensures that there is no water leakage at the relative penetration and telescopic position of the trigger rod 4 and the isolation plate 11. At the same time, when the isolation plate 11 descends to the bottom for cleaning operations, the sealing liquid bag 1101 at the bottom of the isolation plate 11 comes into contact with and is squeezed by the sealing ring 1102, causing the sealing liquid bag 1101 to expand, deform, and expand, filling the penetration gap between the trigger rod 4 and the isolation plate 11 to achieve a further sealing effect. During the cleaning process of the above-mentioned sinking cavity 10 and the trigger rod 4, the electric control valve 501 blocks the air outlet of the air guiding component 5, and the air guiding component 5 can also quickly dry the cleaned sinking cavity 10 and the trigger rod 4.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
