Description

Technical Field

[0001] This utility model relates to the field of counting equipment technology, and in particular to a counter with a hollowed-out back shell. Background Technology

[0002] Prayer beads, also known as rosaries or Buddhist prayer beads, are an important tool used by Buddhist practitioners to record the number of recitations when chanting mantras, reciting Buddha's name, or paying homage to the Buddha. Traditional prayer beads typically consist of a certain number of beads strung together; the user moves one bead each time they recite, counting by mental memorization or visual aids. However, in long, highly repetitive religious rituals or personal practice, relying on manual memory is prone to problems such as omissions, repetitions, or confusion in counting. This can interfere with the user's concentration and may also cause psychological burden and anxiety, affecting the effectiveness of practice.

[0003] With the advancement of electronic technology, electronic counters have gradually emerged as an alternative to traditional rosary counting methods, overcoming the limitations of these methods. These devices are typically equipped with mechanical or electronic sensors that automatically record the bead-turning motion and provide real-time feedback on the current count via a digital display, significantly improving counting accuracy and ease of use. These counters are generally worn on a finger and often feature a sealed casing design to protect the internal circuitry and sensors from external environmental influences.

[0004] However, in practical use, this type of electronic counter still has significant drawbacks. Because it is often worn on the finger and in prolonged contact with the skin during continuous operation, the sealed structure makes it difficult for internal heat to dissipate, and sweat from the hands cannot be effectively released. On the one hand, the accumulated sweat makes the wearer feel sticky and uncomfortable, reducing the user experience; on the other hand, the hot and humid local environment can easily cause aging, short circuits, or decreased sensitivity of internal components, leading to increased failure rates and shortened device lifespan. This problem is particularly pronounced in summer or during prolonged continuous use.

[0005] Therefore, how to provide a counter with a hollowed-out back shell to improve the counter's heat dissipation performance and wearing comfort has become an urgent technical problem to be solved. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a counter with a hollowed-out back shell, which improves the heat dissipation performance and wearing comfort of the counter.

[0007] This utility model is implemented as follows: a back-shell hollow counter, comprising:

[0008] A back cover has a first locking hole in the middle, a heat dissipation hole on each of the left and right sides of the first locking hole, a strap mounting groove on each of the upper and lower sides of the locking hole, and several heat dissipation grooves around each strap mounting groove.

[0009] A top cover has a display window, a large button hole, and a small button hole on the front, and is located at the top of the rear cover;

[0010] A watch strap has a second locking hole in the middle that matches the first locking hole, and passes through the two watch strap mounting slots;

[0011] A screw passes through the first locking hole and the second locking hole in sequence and is threaded to the top cover;

[0012] An MCU is located between the rear cover and the top cover;

[0013] A display screen is disposed within the display window;

[0014] A conductive black strip is connected at one end to the MCU and at the other end to the display screen;

[0015] A single integrated button, consisting of a large button and a small button, is located between the rear shell and the top cover and is connected to the MCU.

[0016] A large silicone keycap is fitted onto the large key and passes through the large key hole;

[0017] A small silicone keycap is fitted onto the small key and passes through the small key hole;

[0018] A metal plate is disposed between the rear shell and the top cover;

[0019] A battery is installed inside the metal plate, with its negative terminal connected to the negative power supply terminal of the MCU through the metal plate, and its positive terminal connected to the positive power supply terminal of the MCU.

[0020] Furthermore, it also includes:

[0021] A transparent protective panel is located on the front of the top cover, covering the display window and the display screen.

[0022] Furthermore, the display screen is an LCD screen.

[0023] The advantages of this utility model are:

[0024] 1. By setting heat dissipation holes on both sides of the first locking hole on the back cover and adding multiple heat dissipation slots on the outside of the strap mounting slot, a highly efficient dual heat dissipation channel is formed: the heat dissipation holes directly promote the convection of internal hot air with the external environment, quickly dissipating the heat generated by the MCU and battery; while the heat dissipation slots located in the strap contact area simultaneously expand the heat dissipation surface area and accelerate sweat evaporation, which not only significantly reduces the internal temperature of the device (avoiding component aging or short circuits), but also directly reduces the accumulation of moisture on the skin contact surface, thereby improving heat dissipation efficiency while eliminating the sticky feeling of wearing, comprehensively solving the reliability reduction and comfort problems caused by the sealed design, and ultimately greatly improving the heat dissipation performance and wearing comfort of the counter.

[0025] 2. The rear shell design includes heat dissipation holes and heat dissipation grooves located around the first locking hole. This hollow structure effectively promotes air circulation, thereby improving the heat dissipation efficiency of the counter, helping to prevent the MCU and other electronic components from degrading or being damaged due to overheating, extending the life of the counter, and improving reliability in high-temperature environments.

[0026] 3. By passing screws through the first and second locking holes in sequence, the back cover, strap, and top cover are securely connected to form an integrated structure. This design reduces the risk of parts loosening or separating, improves the overall mechanical strength of the counter, and makes it more suitable for frequent use or harsh environments.

[0027] 4. The watch band can be easily installed and replaced through the watch band mounting slot, while the integrated buttons, silicone keycaps and other components adopt a modular design, which reduces the assembly complexity in the production process and makes it easy for users or maintenance personnel to quickly replace parts (such as batteries or buttons).

[0028] 5. The integrated button design includes large and small buttons, along with large and small silicone keycaps, providing differentiated operation feedback and tactile feel, improving the usability and comfort of the counter, and is especially suitable for applications that require rapid counting.

[0029] 6. A transparent protective plate covers the display window and screen, effectively preventing the screen from being scratched, dusted, or corroded by moisture, maintaining display clarity, extending the life of the screen, and enhancing the counter's suitability for outdoor or humid environments.

[0030] 7. The battery is connected to the MCU via a metal plate, which serves as the negative terminal connection point. This simplifies the circuit layout and avoids the loosening problems that may occur with traditional soldering or cable connections. It provides a more reliable power supply, reduces the failure rate, and supports more efficient power management.

[0031] 8. The hollowed-out structure of the back cover (including heat dissipation grooves and holes) reduces the amount of material used, lowers the overall weight of the counter, and makes it more portable and comfortable to wear. Attached Figure Description
