Description

Technical Field

[0001] This invention relates to an emergency call device, and more specifically to an emergency call device with waterproof functionality. Background Technology

[0002] The care of elderly people who are frail and have limited mobility is increasingly becoming a social concern. When these elderly people are alone at home, it can be quite troublesome for them to call for help in case of emergencies such as falls or sudden illnesses, leading to delays in responding to emergencies and potentially causing irreparable consequences. An emergency call button is an emergency rescue device specifically designed for the elderly or other special groups. It sends an alarm to a pre-set contact person or rescue center through a one-button trigger and is usually placed by the bedside or in the bathroom. Existing emergency call buttons typically do not have a speaker and send alarms to pre-set contacts or rescue centers wirelessly. Furthermore, emergency call buttons are usually fixed and powered by an external power source (similar to a control switch), rendering them inoperable after a power outage, and they are inconvenient to install and remove. Therefore, existing emergency call buttons often have no other positive effect when used in the home because users cannot pay attention to them in time. The inability to install and remove them also limits their use to specific areas, and their poor waterproof rating results in a short product lifespan. Summary of the Invention

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings: Depend on Figure 1 Combination Figure 2-8 As shown, a waterproof emergency call device includes: Top cover 1, wherein the top cover 1 is provided with button holes 11; The base 4, the upper cover 1 is connected to the base 4 to form an accommodating space 12; the base 4 is provided with a first sealing element 41 at the bottom of the upper cover 1; the base 4 is provided with a power supply cavity 42 for accommodating the power supply. A control circuit board 5 is located within the accommodating space 12 and is fixed to the upper cover 1; a control switch 51 is provided on the control circuit board 5. Control button 2 is configured to correspond to control switch 51; The protective cover 3 is located above the control switch 51 and covers the button hole 11; The fixing screw 6 passes through the control circuit board 5 and connects to the upper cover 1, suspending the control circuit board 5, control button 2, and protective cover 3 above the base 4. The buzzer 7 is located in the accommodating space 12 and is electrically connected to the control circuit board 5; Mounting plate 8, the base 4 is mounted on mounting plate 8 and detachably connected to base 4. The beneficial effects of this invention are that the control circuit board, control button, and protective cover are positioned above the base, and the button hole is blocked by the protective cover. The components within the accommodating space are protected by the first sealing element, resulting in higher waterproofing capability. This invention also has advantages such as simple structure, convenient assembly, reliable operation, and long service life. Specifically, the buzzer of this invention can be a waterproof buzzer. The fixing screws of this invention pass through the control circuit board, pressing the control button and protective cover against the top cover (or the control button and protective cover can be pressed against the top cover by the control circuit board), thus sealing the button hole at the protective cover. This results in a simple structure and reliable sealing. Simultaneously, it separates the control circuit board from the base plate, preventing it from being affected by the base plate and avoiding the impact of small amounts of water entering the base plate on the control circuit board and circuitry.

[0025] The base 4 has an edge 43, and the first sealing element 41 is annular and located on the edge 43. The bottom of the upper cover 1 is fitted over the edge 43 and the first sealing element 41 seals the accommodating space 12. This design allows for a reliable seal at the base, thereby achieving a seal on the accommodating cavity, ensuring reliable sealing and improving the waterproof rating.

[0026] The invention also includes a partition 13, which is disposed on the upper cover 1 and / or the base 4, for dividing the accommodating space 12 into an installation cavity 14; the buzzer 7 is disposed on a buzzer base 71, which is fixed to the upper cover 1, and the buzzer base 71 has a notch 72, which is engaged with the first sealing member 41. Typically, the upper cover or base has a through hole at the buzzer location. The partition ensures that even if a small amount of liquid enters the accommodating space, it will be isolated by the installation cavity, preventing it from affecting the control circuit board and internal components. Simultaneously, the buzzer base can be raised to prevent a small amount of liquid at the partition (inside the installation cavity) from affecting the use of the buzzer.

[0027] The base 4 is equipped with a power cover 44, which covers and shields the power cavity 42. A second sealing element 45 is provided between the power cover 44 and the base 4. Specifically, the bottom of the base 4 is recessed towards its upper surface to form a first groove 46. The power cover 44 is located within the first groove 46. A connecting slope 461 is provided between the first groove 46 and the power cavity 42. The second sealing element 45 is located on the connecting slope 461. This invention features a power cavity, which can house a battery, allowing the product to function normally without an external circuit. Signals can be transmitted via a hummingbird sensor (sound signal) or wirelessly (communication module) over long distances. This design also allows the product to be carried without being fixed to a specific area. The power cover and the second sealing element ensure a reliable seal, preventing water ingress into the power cavity and affecting its lifespan.

[0028] The base 4 has mounting holes 47, and the base 4 is connected to the top cover 1 by mounting screws 471. The mounting holes 47 contain a third sealing element 472. The control circuit board 5 has an indicator light 52. The indicator light indicates the power level, facilitating battery replacement by users or medical personnel. The third sealing element seals the connection between the base and the top cover, ensuring a reliable seal.

[0029] The mounting plate 8 has fixing holes 81 for screw fixing and an adhesive area 82 for pasting. The edge of the mounting plate 8 protrudes upward to form a raised edge 83, and the outer wall of the top cover 1 is located inside the raised edge, forming a gap 84. In use, the mounting plate can be fixed to the wall through the fixing holes, or the product can be fixed to the wall through the adhesive area. This fixing is convenient and reliable. The raised edge provides a water-blocking function, preventing water droplets from entering through the gap between the mounting plate and the top cover. Even if a small amount of water droplets enters the gap, the edge at the base increases the difficulty for water droplets to enter the containment space, thereby improving the product's waterproof capability.

[0030] The base 4 is provided with a countersunk hole 48 and a snap-fit ​​groove 49. The countersunk hole 48 is correspondingly arranged with the fixing hole 81, so that the base 4 covers the fixing hole 81. The mounting plate 8 is provided with a snap-fit ​​part 85 and / or a tensioning part 86 that are adapted to the snap-fit ​​groove 49. The countersunk hole is fitted outside the fixing hole, which serves as a guide and limit. The snap-fit ​​groove facilitates quick disassembly and assembly of the base and the top cover. Removing the base allows for the removal and assembly of the power cover, facilitating battery replacement. The snap-fit ​​part facilitates a reliable connection between the base and the mounting plate. The structure is simple and the connection is convenient. The tensioning part can achieve a reliable connection through tensioning, making the product more stable.

[0031] The control button 2 includes a mounting part 21 and a button part 22. The button part 22 is connected to the mounting part 21 via a connecting part 23, allowing the button part 22 to elastically deform relative to the mounting part 21. The mounting part 21 has an arc-shaped groove 24. Specifically, a perforation 25 is provided between the mounting part 21 and the button part 22. The protective cover 3 includes a cover body 31 and a cover edge 32. The cover body 31 is located above the perforation 25, and the cover edge 32 is located at the mounting hole 47 and extends away from the center of the mounting hole 47. The protective cover 3 is integrally molded from silicone. The arc-shaped groove prevents water droplets from entering the receiving cavity through the perforation, improving the product's sealing performance. The protective cover provides reliable protection and waterproofing.
