Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screen technology, and more specifically, to a capacitive touch screen anti-interference control device. Background Technology

[0002] In today's digital age, capacitive touchscreens, as an important human-computer interaction device, have been widely used in smartphones, tablets, self-service terminals, industrial control equipment, and many other fields. With their high sensitivity, ease of operation, and support for multi-touch, they are highly favored by users and have greatly changed people's lifestyles and work habits. However, with the widespread application of capacitive touchscreens, some problems have also emerged that urgently need to be addressed. These problems not only affect the user experience but also have a certain impact on the performance and lifespan of the devices.

[0003] Capacitive touchscreens work by sensing the electrical current of the human body to achieve touch operation. When a finger touches the screen, due to the electric field of the human body, a coupling capacitor is formed between the user's finger and the touchscreen surface. For high-frequency current, the capacitor is a direct conductor, so the finger draws a small current from the contact point. This current flows out from the electrodes at the four corners of the touchscreen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners. The controller determines the position of the touch point by accurately calculating the ratio of these four currents. However, in real-world environments, there are a large number of dust, hair, and other tiny particles in the air. This dust easily adheres to the surface of the capacitive touchscreen, and over time, it gradually accumulates into a layer of dirt. This layer of dirt alters the electrical characteristics of the touchscreen surface, interfering with the normal transmission of current and causing a decrease in touch sensitivity. When users perform touch operations, they may experience problems such as unresponsive touch, slow response, or even accidental touches, seriously affecting the user experience. Especially in applications requiring high touch accuracy, such as industrial control and medical equipment, inaccurate touches caused by dust contamination can lead to serious consequences and even endanger life.

[0004] Therefore, this application provides a capacitive touchscreen anti-interference control device to solve the problems mentioned in the background art. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide an anti-interference control device for capacitive touch screens. It can wipe the surface of the capacitive touch screen, improve the anti-interference ability of the capacitive touch screen, and thus improve the service life of the capacitive touch screen.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An anti-interference control device for a capacitive touchscreen includes a capacitive touchscreen body. Connecting blocks are fixedly connected to both ends of the capacitive touchscreen body. A groove is carved into the outer end of each connecting block, and a slider is slidably connected within the groove. A receiving groove is carved into the outer end of each slider, and a rod is inserted into the receiving groove. A rotating frame is rotatably connected to the outer end of the rod, and a connecting rod is fixedly connected to the outer end of the rotating frame. A wiping block is fixedly connected to the outer end of the connecting rod. A limiting circular plate located within the receiving groove is fixedly connected to the outer end of the rod. A limiting ring located outside the slider is fixedly connected to the inner wall of the receiving groove. A spring is fixedly connected between the limiting circular plate and the limiting ring. This device allows for wiping of the capacitive touchscreen surface, improving the anti-interference capability of the capacitive touchscreen and thus extending its service life.

[0010] As a further improvement of this utility model, a collection box is fixedly connected to the bottom of the capacitive touch screen body. By setting the collection box, dust that falls off after wiping the capacitive touch screen body can be collected, making it convenient for users to carry out subsequent centralized treatment of the dust.

[0011] As a further improvement of this utility model, the capacitive touch screen body is fixedly connected to both the left and right ends of the capacitive touch screen body, and the outer end of the mounting plate is drilled with mounting holes. By setting the mounting plate and mounting holes, users can easily install the capacitive touch screen body on the wall.

[0012] As a further improvement of this utility model, two mutually symmetrical anti-slip pads are fixedly connected to the outer end of the wiping block. By setting the anti-slip pads, the possibility of the user's hand slipping when touching the wiping block can be reduced.

[0013] As a further improvement of this utility model, the spring is made of stainless steel and the surface of the spring is coated with anti-rust paint. By using stainless steel to make the spring and coating its surface with anti-rust paint, the spring is less prone to corrosion during long-term use, thereby improving the service life of the spring.

[0014] 3. Beneficial Effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1. This device, through its unique structural design, enables the wiping function of the capacitive touchscreen surface. During use, users can easily operate the wiping block to clean the touchscreen surface, promptly removing dust, stains, and other impurities adhering to the screen. If these impurities accumulate on the touchscreen surface over a long period, they will not only affect the sensitivity and accuracy of touch operation, but may also interfere with the normal signal transmission of the touchscreen due to factors such as static electricity, leading to problems such as accidental touches or touch malfunction. By wiping regularly and keeping the touchscreen surface clean, these interference factors are effectively reduced, thereby significantly improving the anti-interference capability of the capacitive touchscreen, extending its service life, and reducing the frequency of device replacement and maintenance costs.

[0017] 2. The collection box at the bottom of the capacitive touchscreen body provides a dedicated space for collecting dust that falls after wiping. During the wiping process, the dust will naturally fall into the collection box, preventing it from scattering everywhere. This makes it convenient for users to collect and dispose of the dust in a centralized manner, keeping the surrounding environment clean. At the same time, the mounting plates fixed at both ends of the capacitive touchscreen body and the mounting holes drilled on them provide convenience for the installation of the device. Users can firmly install the touchscreen on the wall through the mounting holes according to their actual needs. The installation process is simple and quick, improving installation efficiency and enabling the device to be put into use quickly. It is suitable for various places and installation environments.

[0018] 3. The device features two symmetrical anti-slip pads fixedly connected to the outer end of the wiping block. This design fully considers the user's operating experience. When the user pinches the wiping block to rotate or wipe, the anti-slip pads increase the friction between the hand and the wiping block, effectively reducing hand slippage and making the operation more stable and accurate, thus improving comfort and convenience. In addition, the spring is made of stainless steel and coated with anti-rust paint. This design allows the spring to resist the corrosion of moisture, oxygen, and other substances in the air during long-term use, making it less prone to rust. This ensures the spring's elasticity and stability, enabling it to continuously provide a stable reset force to the insertion rod. This ensures that the wiping block and the capacitive touch screen body always maintain a tight fit, improving the reliability and durability of the entire device. Attached Figure Description

[0028] Example:

[0029] Please see Figures 1-4A capacitive touchscreen anti-interference control device includes a capacitive touchscreen body 1. Connecting blocks 2 are fixedly connected to both ends of the capacitive touchscreen body 1. A groove 3 is carved into the outer end of the connecting block 2. A slider 4 is slidably connected within the groove 3. A storage groove 5 is carved into the outer end of the slider 4. A rod 6 is inserted into the storage groove 5. A rotating frame 7 is rotatably connected to the outer end of the rod 6. A connecting rod 8 is fixedly connected to the outer end of the rotating frame 7. A wiping block 9 is fixedly connected to the outer end of the connecting rod 8. A limiting circular plate 10 located within the storage groove 5 is fixedly connected to the outer end of the rod 6. A limiting ring 11 located outside the slider 4 is fixedly connected to the inner wall of the storage groove 5. A spring 12 is fixedly connected between the limiting circular plate 10 and the limiting ring 11. This device can wipe the surface of the capacitive touchscreen, improving its anti-interference capability and thus extending its service life.

[0030] Please see Figures 1-3 A collection box 101 is fixedly connected to the bottom of the capacitive touch screen body 1. By setting the collection box 101, dust that falls off after wiping the capacitive touch screen body 1 can be collected, making it convenient for users to carry out subsequent centralized dust disposal. Mounting plates 102 are fixedly connected to both the left and right ends of the capacitive touch screen body 1. Mounting holes 103 are drilled on the outer end of the mounting plate 102. By setting the mounting plate 102 and the mounting holes 103, users can easily install the capacitive touch screen body 1 on the wall.

[0031] Please see Figures 2-4 Two symmetrical anti-slip pads 901 are fixedly connected to the outer end of the wiping block 9. By setting the anti-slip pads 901, the possibility of the user's hand slipping when touching the wiping block 9 can be reduced. The spring 12 is made of stainless steel and the surface of the spring 12 is coated with anti-rust paint. By using stainless steel to make the spring 12 and coating its surface with anti-rust paint, the spring 12 is not easy to be corroded during long-term use, thereby improving the service life of the spring 12.

[0032] Working principle: When using this device, the user holds the wiping block 9 by hand. The wiping block 9 can be rotated 90° by the rotational action between the insert rod 6 and the rotating frame 7. Please refer to [link / reference].
