[0002] In modern society, women and vulnerable groups face potential safety threats, making anti-wolf alarm devices an important self-protection tool. Most existing anti-wolf alarm devices trigger the alarm via a latch; however, in actual use, the latch is prone to accidental loss or dislodgement. Once the latch falls off, the device not only fails to trigger the alarm properly but may also become completely ineffective, failing to provide protection in emergencies.

[0003] Meanwhile, the structural design of traditional anti-wolf alarms often neglects the requirements for dust prevention and stability. When exposed to the outdoors for a long time or carried around in daily life, dust can easily enter the device, affecting the performance and lifespan of key components such as the buzzer and circuits. Insufficient stability of component connections can also cause the device to malfunction when shaken or bumped, reducing its reliability.

[0004] From a circuit and functional perspective, some products have limited alarm sound effects, making them ineffective in deterring criminals; the integration and practicality of lighting warning functions are also poor, failing to meet alarm and lighting needs simultaneously in complex environments. Furthermore, the existing devices have simple hook and carrying structures, lacking convenient and stable hanging methods, making them inconvenient for daily carrying and difficult to access in emergencies. These shortcomings significantly limit the actual protective effect and user experience of anti-wolf alarm devices. Utility Model Content

[0037] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model embodiment provides a high-decibel anti-wolf alarm device with anti-pin drop function, including:

[0039] The housing assembly includes a front housing 1, a rear housing 2, a dust cover 3, and a battery cover 4. The front housing 1 and the rear housing 2 are adapted to each other. The top of the front housing 1 and the rear housing 2 are provided with a limiting structure for limiting the position of the pin 10 after the pin 10 is pulled out. The limiting structure includes a first limiting part 1-1 and a second limiting part 2-1.

[0040] Specifically, the front shell 1 and the rear shell 2 are connected to form the overall outer shell of the device, providing a protective space for the internal components; while the first limiting part 1-1 and the second limiting part 2-1 work together after the pin 10 is pulled out to lock and restrict the pin 10 from both sides, preventing the pin 10 from completely detaching from the device, ensuring that the pin 10 is always connected to the device, and preventing loss or malfunction.

[0041] The sound-generating component is controlled by a main control circuit board 6 and a buzzer 7. The main control circuit board 6 is electrically connected to the buzzer 7 and the plug 10 respectively. The plug 10 is inserted and removed to control the circuit to turn on and off, so that the buzzer 7 can sound or turn off.

[0042] Specifically, the main control circuit board 6, as the core control component, receives the insertion and removal signals of the plug 10. When the plug 10 is pulled out, the circuit is turned on, and the main control circuit board 6 drives the buzzer 7 to work and make a sound. When the plug 10 is inserted, the circuit is turned off, and the buzzer 7 stops making a sound, thus realizing the triggering and shutdown control of the alarm function.

[0043] Optical and power supply components include a lens 8, a button cell battery 9, and an insulating sheet 11. The lens 8 is used for light transmission, the button cell battery 9 is used for providing electrical energy, and the insulating sheet 11 is used for battery insulation control.

[0044] Specifically, the button battery 9 provides power support for the operation of the entire device's circuitry, the insulating sheet 11 isolates the positive and negative terminals of the battery when the device is not in use, preventing battery self-discharge loss, and the lens 8 refracts and converges the light emitted by the light-emitting elements inside the device, enhancing the concentration and illumination effect of the light.

[0045] The hook assembly 12 and the pin 10 are connected to allow the device to be suspended and carried.

[0046] Specifically, the hook assembly 12 connects the entire device together with the pin 10, making it convenient for users to hang the device on keychains, backpacks, and other items for easy carrying and access, while ensuring the stability of the connection between the pin 10 and the device.

[0047] In this embodiment, the front shell 1 is provided with inclined protrusions 1-2 around its perimeter for connecting with the rear shell 2, the front shell 1 is provided with a first circular hole 1-3 on its upper part for the sound of the buzzer 7 to diffuse, and the front shell 1 is provided with a mounting hole 1-4 on its lower part for mounting the lens 8; the front shell 1 is provided with a battery compartment 1-5 for accommodating the button battery 9 inside, and the front shell 1 is provided with a first limiting part 1-1 on its top part for engaging with the rear shell 2.

[0048] Specifically, the inclined boss 1-2 cooperates with the corresponding structure of the rear shell 2 to achieve a tight connection between the front shell 1 and the rear shell 2; the first round hole 1-3 provides a propagation channel for the sound emitted by the buzzer 7, ensuring that the sound diffuses smoothly; the mounting hole 1-4 is used to fix the lens 8 to ensure that the lens 8 is in an accurate position; the battery compartment 1-5 provides a space for the button battery 9 to be placed in an orderly manner; the first limiting part 1-1 and the second limiting part 2-1 of the rear shell 2 engage to form a limiting structure to prevent the pin 10 from falling off.

[0049] In this embodiment, the rear shell 2 has protruding buckle positions 2-2 around its perimeter that are adapted to the inclined boss 1-2, a square opening 2-3 for installing the battery cover 4 is provided in the middle of the rear shell 2, and a second limiting part 2-1 that engages with the front shell 1 is provided on the top of the rear shell 2.

[0050] Specifically, the protruding buckle 2-2 engages with the inclined protrusion 1-2 of the front shell 1 to achieve a firm connection between the front shell 1 and the rear shell 2 and prevent the shell from loosening; the square opening 2-3 provides an installation position for the battery cover 4, making it easy to install and remove the battery cover 4 to replace the battery; the second limiting part 2-1 engages with the first limiting part 1-1 of the front shell 1 to limit the pin 10 and prevent the pin 10 from falling off.

[0051] In this embodiment, the inner side of the dust cover 3 is provided with a hollow cylinder 3-1 that engages with the protruding column of the inner structure of the circular recess of the front shell 1, and the dust cover 3 is provided with an arc protrusion 3-2 around the perimeter and center to balance the internal stress. The dust cover 3 covers the outer side of the first circular hole 1-3.

[0052] Specifically, the hollow cylinder 3-1 engages with the structural protrusion of the front shell 1 to achieve the fixed installation of the dust cover 3; the arc protrusion 3-2 can disperse the internal stress generated during the installation and use of the dust cover 3, preventing the dust cover 3 from deforming and being damaged; the dust cover 3 covers the first circular hole 1-3, which can block external dust from entering the equipment through the circular hole and protect the circuit components from dust.

[0053] In this embodiment, the battery cover 4 is convex in shape. The long side of the battery cover 4 is provided with a slanted buckle 4-1 that connects to the rear shell 2. The short side of the battery cover 4 is provided with a second round hole 4-2. The middle of the battery cover 4 is provided with a long rectangular hole 4-3 for the insulating sheet 11 to be pushed and pulled. The insulating sheet 11 is disposed inside the battery cover 4 through the long rectangular hole 4-3 to control the insulation of the button battery 9.

[0054] Specifically, the convex design allows the battery cover 4 to fit the square opening 2-3 of the back cover 2, facilitating installation and disassembly; the angled buckle 4-1 engages with the corresponding structure of the back cover 2 to secure the battery cover 4; the second round hole 4-2 is a screw lock hole, requiring a screwdriver to remove the screws from the round hole of the battery cover when replacing the battery; the elongated square hole 4-3 provides a moving channel for the insulating sheet 11, allowing users to control its insulation status against the battery by pushing and pulling the insulating sheet 11, making operation convenient.

[0055] See Figure 6 In this embodiment, the main control circuit board 6 includes a main control chip U1, a capacitor C1, a resistor R1, a white light D1, a switch SW-PB, and a battery connection terminal for connecting the button battery 9; the capacitor C1 is used for circuit filtering and energy storage, the resistor R1 is used for voltage division and current limiting protection, the switch SW-PB is used to control the white light D1 to turn on and off, and to control the white light D1 to emit an SOS distress light and strobe light; the button battery 9 supplies power to the main control circuit board 6 through the battery connection terminal.

[0056] Specifically, the main control chip U1 is responsible for coordinating and controlling the operation of various components; capacitor C1 filters noise in the circuit, stabilizes the voltage, and stores some electrical energy; resistor R1 protects circuit components from damage by excessive current or voltage by limiting current and distributing voltage; switch SW-PB controls the white light D1 to turn on and off by linking with button 5, realizing the lighting and warning functions; the battery connection terminal transmits the power of button battery 9 to the main control circuit board 6 to power various components.

[0057] In this embodiment, four AG13 / LR44 button batteries are used to power the product, each with a voltage of 1.5V and a capacity of 160mAh.

[0058] In this embodiment, lens 8 is an optical lens 8, and the light from the light-emitting element in the device converges after passing through lens 8.

[0059] Specifically, the optical lens 8 uses the principle of light refraction to converge the divergent light emitted by the light-emitting element. After the light passes through the lens 8, it forms a beam of light at a 20-degree angle, creating a concentrated beam of light, which increases the brightness and illumination distance of the light, and enhances the lighting and warning effect of the equipment.

[0060] In this embodiment, the hook assembly 12 includes a hook 12-1, an open single loop 12-2, a figure-eight connecting buckle 12-3, and a double loop 12-4; the hook 12-1 is provided with a limiting member 12-11 to control the opening and closing of the opening, the open single loop 12-2 connects the hook 12-1 and the figure-eight connecting buckle 12-3, and the figure-eight connecting buckle 12-3 is connected to the pin 10 through the double loop 12-4.

[0061] Specifically, the limiting component 12-11 allows the opening of the hook 12-1 to be opened and closed flexibly, facilitating the connection of the hook assembly 12 with other items; the single loop 12-2 of the opening and the figure-eight connecting buckle 12-3 and double loop 12-4 are connected in sequence to form a multi-segment connection structure, which enhances the flexibility and durability of the hook assembly 12, ensures the stable connection between the pin 10 and the hook assembly 12, and prevents the equipment from falling off.

[0062] In this embodiment, the sound control component also includes a button 5; the button 5 is a side-press button 5, which is linked with the switch on the main control circuit board 6 to control the white light to turn on and off and to switch the flashing mode.

[0063] Specifically, the side-mounted push-button 5 is convenient for users to operate. By linking with the switch on the main control circuit board 6, it changes the circuit connection state and controls the white light to turn on and off. At the same time, it can switch between different flashing modes to adapt to the lighting and distress needs in different scenarios.

[0064] The working principle of this utility model is to achieve functions such as preventing the pin 10 from falling off, high-decibel alarm, and lighting through the cooperation of mechanical structure and the on / off control of circuit, as detailed below:

[0065] When the user removes the insulating sheet 11, the button battery 9 forms a circuit with the main control circuit board 6 through the battery spring, supplying power to the entire device, and the device enters standby mode. At this time, the plug 10 is inserted into the 3.5mm socket on the main board circuit board, the circuit is disconnected, and the buzzer 7 does not work.

[0066] In case of danger, pull out pin 10. Pin 10 separates from the 3.5mm socket, the circuit is connected, and the main control circuit board 6 starts driving the buzzer 7. The white LED D1 will flash synchronously. The buzzer 7 is composed of a piezoelectric ceramic plate and a metal plate. The piezoelectric ceramic plate vibrates under the action of high-frequency alternating current (frequency 3.5±0.7KHZ) using the piezoelectric effect. The metal plate assists in the vibration and amplifies the sound, thus emitting a high-decibel sound to deter criminals and signal for help. At the same time, because the front shell 1 and the rear shell 2 have structural limiting at the top, after the two are tightly fitted together, the pin 10 will still be fixed inside the product after being pulled out and will not fall off, ensuring normal use afterwards. After the danger has passed, insert pin 10 back into the 3.5mm socket. The circuit is broken, the buzzer 7 stops sounding, and the white LED D1 stops flashing synchronously.

[0067] The lighting function is controlled by button 5 on the side. A short press of button 5 controls the on / off state and flashing of the white LED patch, with modes of high beam - medium beam - SOS - off. The light emitted by the LED passes through lens 8, which, as an optical lens, allows the light to converge at a 20-degree angle, improving lighting efficiency and meeting the lighting or warning needs of different scenarios. The hook assembly 12 is connected to the pin 10 through a series structure of hook 12-1, open single loop 12-2, figure-eight connecting buckle 12-3, and double loop 12-4, which not only facilitates user carrying of the device but also further enhances the connection stability between the pin 10 and the device. The dust cover 3 covers the outside of the small round hole on the front shell 1, preventing external dust from entering the device and affecting the normal operation of the circuit. When the battery power is low, the button battery 9 can be replaced by opening the battery cover 4 to ensure continuous operation of the device.

[0068] The method of using this utility model is as follows:

[0069] Equipment startup preparation: After receiving the equipment, the user locates the long rectangular hole 4-3 in the middle of the battery cover 4 and pulls out the insulating sheet 11 from the hole. After the insulating sheet 11 is pulled out, the button battery 9 contacts the battery spring, the circuit is completed, and the equipment enters the standby state.

[0070] Daily carrying operation: Carry the device via the hook assembly 12. Open the limiting piece 12-11 of the hook 12-1, hang the hook 12-1 on a key ring, backpack strap, or other suitable location, and then close the limiting piece 12-11 to secure the opening of the hook 12-1. At this time, the hook assembly 12 is connected in series with the pin 10 through the single loop 12-2, the figure-eight connecting buckle 12-3, the double loop 12-4, and the opening, ensuring stable suspension and preventing the device from easily falling off.

[0071] Alarm function operation: In case of danger, forcefully pull out pin 10. Pin 10 will separate from the 3.5mm socket on the main board circuit board, completing the circuit. The buzzer 7 will emit a high-decibel sound under the influence of current. After the danger has passed, reinsert pin 10 into the 3.5mm socket. The circuit will break, and the buzzer 7 will stop sounding. Due to the structural constraints at the top of the front shell 1 and the rear shell 2, pin 10 remains fixed inside the product after being pulled out and will not fall out or be lost.

[0072] Lighting function operation: When lighting or warning is needed, press button 5 on the side. When button 5 is pressed briefly, the white LED patch will be turned on and off and will flash. The modes are high light - medium light - SOS - off, so as to meet the lighting and warning needs in different scenarios.

[0073] Battery replacement steps: If the device's sound becomes quieter or the light dims, it indicates that the battery is low. Locate the square opening 2-3 in the middle of the back cover 2, use a screwdriver to remove the screw inside the small round hole, then remove the battery cover 4. Take out the four AG13 / LR44 button batteries 9 inside, and replace them with new button batteries of the same model according to the positive and negative polarity. Then, connect and secure the battery cover 4 to the back cover 2 using the diagonal buckle 4-1 on the long side, and tighten the screws into the round holes to ensure that the battery cover 4 is installed in place.

[0074] Routine maintenance notes: Dust cover 3 prevents dust from entering the equipment. Avoid disassembling it during daily use. If there is dust on the surface of dust cover 3, wipe it gently with a dry cloth to maintain its dust-blocking function and ensure normal circuit operation.

[0075] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be understood that, based on the technical concept of the present invention, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not depart from the technical concept of the present invention, the technical solutions obtained by these conventional adjustments or further innovations also fall within the protection scope of the claims of the present invention.
