[0015] Compared with the prior art, the portable alarm device provided by this utility model has the following advantages:

[0016] 1. An embodiment of this utility model provides a portable alarm device, which includes a housing assembly, a warning assembly, and a stretching assembly. The warning assembly is disposed inside the housing assembly, and the stretching assembly extends at least partially into the housing assembly and is slidably connected to it. A touch button is provided on the side of the warning assembly facing the stretching assembly. The warning assembly and the stretching assembly are held together by the touch button. When the stretching assembly is subjected to external force, it moves closer to or away from the touch button. When the portable alarm device is in a normal, non-alarm state, the warning assembly and the stretching assembly are held together by the touch button, and the switch of the warning assembly is off. In the event of a sudden emergency, the stretching assembly is moved away from the touch button by external force, separating the stretching assembly from the touch button and closing the switch of the warning assembly. The portable alarm device then emits an alarm and / or flashes a light.

[0017] It should be noted that under normal circumstances, the alarm component's switch is in the open state because the pull-out component is connected to the touch button, and no alarm will sound. In an emergency, the user can pull the pull-out component directly from the housing component with external force. When the pull-out component separates from the touch button, the alarm component's switch immediately closes, triggering the alarm. This design ensures both sensitive alarm function and accurate alarm response, minimizing false alarms and greatly improving the alarm effectiveness and user experience of the portable alarm device in emergency situations.

[0018] 2. In the portable alarm device provided in this utility model embodiment, a control circuit module is provided. The control circuit module includes a control circuit board, an energy storage component, and an alarm switch. The energy storage component is electrically connected to the input terminal of the control circuit board, the warning component is electrically connected to the output terminal of the control circuit board, and the alarm switch is electrically connected to the control circuit board when closed. It can be understood that the control circuit board is used to control the energy storage component to drive the warning component to work when the alarm switch is closed, so as to issue an alarm and / or flash the light to the outside world.

[0019] 3. In the portable alarm device provided in this utility model embodiment, by setting a limiting member on the inner wall surface of the upper shell and the lower shell near the opening, it can prevent the user from accidentally pulling out the stretching component by external force, so that the stretching component is separated from the touch button and thus triggers the portable alarm device to work. Through this design, the false touch rate of the stretching component can be reduced, and the false alarm situation can be further avoided.

[0020] 4. In the portable alarm device provided in this embodiment of the utility model, the cover and the limiting protrusion are made into an integral structure, and a limiting groove is provided on the inner wall surface of the upper shell and the lower shell. The limiting groove and the limiting protrusion are positioned correspondingly, so that the limiting protrusion can slide and engage with the limiting groove. The contact area between the limiting protrusion and the limiting groove is smaller than the area of ​​the limiting groove. That is, the limiting protrusion allows the cover to slide only a certain distance within the limiting groove. Through this design, the separation between the tension component and the shell component in the portable alarm device can be avoided, thereby ensuring the reusability of the portable alarm device.

[0021] 5. In the portable alarm device provided in this utility model embodiment, a remote locator is set inside the tension component, enabling the portable alarm device to have a remote positioning function. With this design, when the portable alarm device is lost, stolen, or the user is in a dangerous situation, the user who has connected to the remote locator in advance can remotely locate the tension component through an electronic device, thereby protecting the user's personal property and personal safety and improving the user experience.

[0022] 6. In the portable alarm device provided in this embodiment of the utility model, the control circuit board is provided with a flexible contact. One end of the flexible contact is electrically connected to the control circuit board, and the other end is electrically connected to the buzzer module. With this design, the buzzer module can be triggered to work when the switch of the alarm component is closed.

[0023] Furthermore, the operation of the buzzer module can also be controlled through the first switch assembly. In the event of a false alarm, the first switch assembly can be pressed quickly to stop the buzzer module from working and the portable alarm device from emitting alarms to the outside world, thereby improving the operability of the portable alarm device.

[0024] 7. In the portable alarm device provided in this embodiment of the utility model, by setting a first button and a first switch body, pressing the first button can cause the first switch body to close or open. When the first switch body is closed, the energy storage device drives the buzzer module to work. Through the first switch assembly, the buzzer module can not only trigger the portable alarm device to work when the stretching assembly is separated from the touch button, but also be activated by manually pressing the first button, thereby emitting a buzzer alarm, which improves the practicality and versatility of the portable alarm device.

[0025] 8. In the portable alarm device provided in this utility model embodiment, by setting a buffer between the first button and the control circuit board and between the upper shell and the energy storage component, the control circuit board and the energy storage component can be buffered and shock-reduced when the user carries the portable alarm device, so as to avoid damage to the circuit components such as the control circuit board and the energy storage component, thereby extending the service life of the portable alarm device.

[0026] 9. In the portable alarm device provided in this utility model embodiment, the light-emitting element can be used to emit different types of light such as illumination lamps, ambient lights, and strobe lights. The light emitted by the light-emitting element shines to the outside through the transparent shell, which is suitable for various emergency situations. The light-shielding element is used to block the light source that shines on the control circuit board when the light-emitting element is working, so as to protect the control circuit board and energy storage components inside the portable alarm device, thereby extending the service life of the portable alarm device.

[0027] 10. In the portable alarm device provided in this embodiment of the utility model, by setting a second button and a second switch body, pressing the second button can cause the second switch body to close or open. When the second switch body is closed, the energy storage component drives the light-emitting component to work. The second switch assembly enables the light-emitting component to not only trigger the portable alarm device to work when the stretching component is separated from the touch button, but also to work by manually pressing the second button, thereby providing illumination in poor light conditions or when calling for help from the outside world, further improving the practicality and versatility of the portable alarm device.

[0047] It should be noted that the terms "first" and "second" in the specification and claims of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0048] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0049] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0050] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0051] Please see Figure 1 and Figure 2The present invention provides a portable alarm device 100, which includes a housing assembly 1, a warning assembly 2 and a stretching assembly 3. The housing assembly 1 has a receiving cavity 10 inside, the warning assembly 2 is installed in the receiving cavity 10, and the housing assembly 1 also has an opening 20 communicating with the receiving cavity 10. The stretching assembly 3 is at least partially slidably inserted into the receiving cavity 10 through the opening 20.

[0052] Furthermore, a touch button 21 is provided on the side of the warning component 2 facing the stretching component 3. The warning component 2 and the stretching component 3 can be held together by the touch button 21. The stretching component 3 is brought closer to or away from the touch button 21 by external force. The switch of the warning component 2 is controlled by the touch button 21. When the stretching component 3 is held together by the touch button 21 on the warning component 2, the switch of the warning component 2 is turned off. When the stretching component 3 is separated from the touch button 21, the switch of the warning component 2 is turned off.

[0053] The portable alarm device 100 provided by this utility model has a receiving cavity 10 inside the housing assembly 1. The internal space of the receiving cavity 10 is used to accommodate and install the warning component 2 and the stretching component 3. The warning component 2 is installed in the receiving cavity 10, and the stretching component 3 is at least partially slidably inserted into the receiving cavity 10 through the opening 20. The stretching component 3 can abut against the touch button 21 on the warning component 2. When the stretching component 3 is subjected to external force, it will move closer to or further away from the touch button 21.

[0054] Understandably, the switch of the warning component 2 is controlled by the touch button 21, which is mounted on the side of the warning component 2 facing the stretching component 3. When the portable alarm device 100 is in a normal non-alarm state, the warning component 2 and the stretching component 3 are held together by the touch button 21, and the switch of the warning component 2 is off. In the event of a sudden emergency, the stretching component 3 is moved away from the touch button 21 by external force, and the separation of the stretching component 3 from the touch button 21 causes the switch of the warning component 2 to close, at which time the portable alarm device 100 emits an alarm and / or flashes a light.

[0055] In particular, the portable alarm device 100 can emit an alarm to the outside world, generally attracting attention in noisy environments. It is suitable for rapid use in emergencies and has a wide range of applications. The portable alarm device 100 can be used in various public places, such as parking lots, parks, and campuses. In these places, the portable alarm device 100 can attract the attention of those around, thereby protecting one's safety. The portable alarm device 100 can also be used by people out at night, such as women, the elderly, and children. As a practical self-defense tool, the portable alarm device 100 can promptly sound an alarm when encountering danger, protecting the safety of oneself and those around them. The portable alarm device 100 can also be used in specific environments such as buses, subways, trains, and high-speed trains. In these environments, the portable alarm device 100 can help passengers quickly seek help when encountering harassment or danger.

[0056] In addition, in the event of a sudden emergency, the method of using external force to separate the tension component 3 from the touch button 21 and trigger the portable alarm device 100 is simpler and more convenient than finding the relevant control button on the alarm.

[0057] It should be further explained that under normal circumstances, the switch of the warning component 2 is in the open state because the tension component 3 is connected to the touch button 21, and no alarm will be triggered; in case of emergency, the user can pull the tension component 3 directly out of the housing component 1 by external force. When the tension component 3 is separated from the touch button 21, the switch of the warning component 2 will immediately be closed and an alarm will be triggered. Through this design, the alarm function can be sensitively realized.

[0058] Furthermore, since the user needs to apply a pulling force to the side of the stretching component 3 away from the touch button 21 to make the stretching component 3 gradually move away from the touch button 21 on the warning component 2, and the portable alarm device 100 is triggered to work when the stretching component 3 is separated from the touch button 21, it can also accurately alarm to minimize false alarms, greatly improving the alarm effect of the portable alarm device 100 in emergency situations and its user experience, and solving the technical problem that the existing alarm devices have poor alarm effects in emergency situations.

[0059] In some embodiments, the end of the stretching component 3 away from the touch button 21 is provided with a lanyard hole 34. By attaching a pull rope to the lanyard hole 34, the other end of the pull rope can be wrapped around the hand or tied to a backpack or other personal item. In case of emergency, pulling the housing component 1 can cause the stretching component 3 to be subjected to external force and move away from the touch button 21. When the stretching component 3 is separated from the touch button 21, the warning component 2 will issue an alarm and / or flash a light to the outside world.

[0060] Please continue reading. Figure 1 and Figure 2 The cavity 10 is also equipped with a control circuit module 4. The control circuit module 4 includes a control circuit board 41, an energy storage component 42 and an alarm switch 43. The warning component 2 is electrically connected to the control circuit board 41; the energy storage component 42 is electrically connected to the control circuit board 41; and the alarm switch 43 is electrically connected to the control circuit board 41 when closed.

[0061] It should be noted that in this embodiment, both the energy storage device 42 and the alarm switch 43 are mounted on the control circuit board 41. The alarm switch 43 is located at the end closest to the touch button 21. When the tensioning component 3 abuts against the touch button 21, the alarm switch 43 also abuts against the touch button 21. The energy storage device 42 is located adjacent to the end of the alarm switch 43 furthest from the touch button 21. When the tensioning component 3 abuts against the touch button 21, the alarm switch 43 is open; when the tensioning component 3 separates from the touch button 21, the alarm switch 43 is closed, and the energy storage device 42 drives the warning component 2 to operate.

[0062] In this embodiment of the present invention, the portable alarm device 100 is provided with a control circuit module 4 equipped with an alarm switch 43, which can be used to control the closing and opening of the warning component 2. The energy storage component 42 is electrically connected to the input terminal of the control circuit board 41, the warning component 2 is electrically connected to the output terminal of the control circuit board 41, and the alarm switch 43 is electrically connected to the control circuit board 41 when closed, so as to realize that the energy storage component 42 supplies power to the warning component 2.

[0063] Understandably, the control circuit board 41 is used to control the energy storage unit 42 to drive the warning component 2 to work when the alarm switch 43 is closed, so as to send an alarm and / or flash the light to the outside world.

[0064] In some embodiments, the energy storage device 42 is a rechargeable battery. The portable alarm device 100 is also provided with a charging interface 44 electrically connected to the control circuit board 41. The type of charging interface 44 includes, but is not limited to, Type-C and USB-C. By plugging an external power supply into the charging interface 44, the energy storage device 42 can be charged to ensure the battery life of the portable alarm device 100 in the event of an emergency.

[0065] In addition, as another alternative implementation, the energy storage device 42 can also be a disposable battery. Disposable batteries cannot be recharged and need to be replaced with new batteries after they are used up, that is, there is no need to set up a charging interface 44.

[0066] Please see Figure 2 and Figure 3The housing assembly 1 includes a coverable upper housing 11 and a lower housing 12; a first limiting member 111 is provided on the inner wall surface of the upper housing 11 near the opening 20, and a second limiting member 121 is provided on the inner wall surface of the lower housing 12 near the opening 20. The stretching assembly 3 is slidably disposed between the upper housing 11 and the lower housing 12 through the first limiting member 111 and the second limiting member 121.

[0067] In the portable alarm device 100 provided in this embodiment of the present invention, a first limiting member 111 and a second limiting member 121 are respectively provided on the inner wall surface of the upper housing 11 and the lower housing 12 near the opening 20. This can prevent the user from accidentally pulling out the stretching component 3 by external force, causing the stretching component 3 to separate from the touch button 21 and thus triggering the portable alarm device 100 to work. Through this design, the false touch rate of the stretching component 3 can be reduced, and false alarms can be further avoided.

[0068] In some embodiments, the first limiting member 111 and the second limiting member 121 can enhance the connection stability between the tensioning component 3 and the housing component 1, ensuring that the tensioning component 3 will not easily slide between the upper housing 11 and the lower housing 12, thereby accidentally triggering the switch of the portable alarm device 100; the first limiting member 111 and the second limiting member 121 can also play a protective role for the tensioning component 3.

[0069] In this embodiment, the first limiting member 111 and the second limiting member 121 are actually single-layer limiting plates respectively embedded and fixed on the upper housing 11 and the lower housing 12. The side of the first limiting member 111 near the inner wall of the upper housing 11 and the side of the second limiting member 121 near the inner wall of the lower housing 12 can be determined according to the specific shape of the inner wall of the housing assembly 1. On the side of the first limiting member 111 and the second limiting member 121 near the tensioning component 3, there is a protruding structure made of elastic or plastic material. The protruding structure can prevent the user from easily separating the tensioning component 3 from the touch button 21, thereby accidentally triggering the portable alarm device 100.

[0070] Please see Figure 2 and Figure 4 As an optional implementation, the stretching component 3 includes a cover 31 and a limiting protrusion 32, the cover 31 and the limiting protrusion 32 being an integral structure; the inner wall surfaces of the upper shell 11 and the lower shell 12 are correspondingly provided with limiting grooves 30, the limiting protrusion 32 is slidably disposed in the limiting groove 30, and the contact area between the limiting protrusion 32 and the limiting groove 30 is smaller than the area of ​​the limiting groove 30.

[0071] Understandably, in the portable alarm device 100 provided in this embodiment of the present invention, by providing a limiting groove 30 on the inner wall surface of the upper housing 11 and the lower housing 12, and by having the limiting groove 30 cooperate with the limiting protrusion 32 of the stretching component 3, it can be ensured that the stretching component 3 is at least partially located inside the housing component 1. When the stretching component 3 slides relative to the inner wall surface of the upper housing 11 and the lower housing 12, the limiting protrusion 32 can slide on the inner wall surface of the limiting groove 30, so that the stretching component 3 slides along the length direction of the housing component 1. When the user pulls the stretching component 3 away from the housing component 1 by external force, and the limiting protrusion 32 slides to abut against the inner side wall of the limiting groove 30, the limiting protrusion 32 and the limiting groove 30 form a locking structure to ensure that the cover 31 will not fall completely out of the receiving cavity 10.

[0072] It should be noted that the limiting protrusion 32 can slide with the limiting groove 30. The contact area between the limiting protrusion 32 and the limiting groove 30 when sliding is smaller than the area of ​​the limiting groove 30, so that the limiting protrusion 32 can only slide a certain distance within the limiting groove 30. That is, the cover 31 can only slide the same distance. Through this design, the separation between the tension component 3 and the upper housing 11 and the lower housing 12 in the portable alarm device 100 can be avoided, thereby ensuring the reusability of the portable alarm device 100.

[0073] In addition, the limiting grooves 30 provided on the inner wall surfaces of the upper housing 11 and the lower housing 12 can also reduce the weight of the portable alarm device 100.

[0074] Please see Figure 2 and Figure 5 As another optional implementation, a remote locator 33 is provided inside the tension component 3, enabling the portable alarm device 100 to have a remote positioning function. In the portable alarm device 100 provided in this embodiment of the present invention, the remote locator 33 is provided inside the tension component 3, enabling the portable alarm device 100 to have a remote positioning function.

[0075] It should be noted that, through this design, when the portable alarm device 100 is lost, stolen, or the user is in a dangerous situation, the user who has connected to the remote locator 33 in advance can remotely locate the stretching component 3 through the electronic device, thereby protecting the user's personal property and safety and improving the user experience.

[0076] In this embodiment of the present invention, the end of the stretching component 3 away from the touch button 21 is provided with a lanyard hole 34. By attaching a pull rope to the lanyard hole 34, the other end of the pull rope can be wrapped around the hand or tied to a backpack or other personal item. In case of emergency, pulling the housing component 1 will cause the stretching component 3 to be subjected to external force and thus move away from the touch button 21. When the stretching component 3 is separated from the touch button 21, the warning component 2 will issue an alarm and / or flash a light to the outside world.

[0077] Understandably, when the tensioning assembly 3 is completely separated from the housing assembly 1, the remote positioner 33 inside the tensioning assembly 3 still has the remote positioning function, and the warning assembly 2 inside the tensioning assembly 3 and the housing assembly 1 can be used separately or in conjunction.

[0078] Please see Figure 6 , Figure 7 and Figure 8 The warning component 2 includes an alarm component 22, which includes a first switch component 221, a resilient contact 222, and a buzzer module 223. The first switch component 221 is located at one end of the control circuit board 41, and the resilient contact 222 and the buzzer module 223 are located at the other end of the control circuit board 41.

[0079] In the portable alarm device 100 provided in this embodiment of the present invention, a sound outlet 40 is provided on the lower housing 12 to cooperate with the buzzer module 223. The buzzer module 223 can be used to emit a buzzing alarm, so that the alarm sound can be amplified through the sound outlet 40, which is suitable for various emergency situations. In this embodiment, the buzzer module 223 is specifically a buzzer plate, which can emit a sound in the range of 100 decibels to 120 decibels. When the buzzer plate has sufficient power in the energy storage device 42, it can emit a high-decibel buzzer alarm of 120 decibels.

[0080] Furthermore, in this embodiment, the elastic contact 222 is disposed on the side of the control circuit board 41 away from the control circuit board 41. One end of the elastic contact 222 is electrically connected to the control circuit board 41, and the other end is electrically connected to the buzzer module 223. In this embodiment, the elastic contact 222 is mounted on the control circuit board 41 by soldering, and the elastic contact 222 is located between the control circuit board 41 and the buzzer module 223. The buzzer module 223 is provided with a metal contact that abuts against the elastic contact 222. With this design, the buzzer module 223 can be triggered to work when the switch of the warning component 2 is closed.

[0081] Among them, the elastic contact 222 is made of conductive material. The material of the elastic contact 222 includes, but is not limited to, silver-nickel alloy, silver-cadmium alloy, pure silver, beryllium copper alloy and copper. In order to pursue better conductivity and reduce contact resistance, composite materials can also be used, such as adding metal materials such as nickel-chromium to improve performance.

[0082] It should be noted that the first switch assembly 221 is located at the end of the control circuit board 41 away from the elastic contact 222 and the buzzer module 223. The operation of the buzzer module 223 can also be controlled through the first switch assembly 221. In the event of a false alarm, the first switch assembly 221 can be pressed quickly to stop the buzzer module 223 from working. At this time, the portable alarm device 100 stops emitting alarms to the outside world, thereby improving the operability of the portable alarm device 100 and the user experience of the portable alarm device 100.

[0083] Furthermore, the first switch assembly 221 includes a first button 2211 and a first switch body 2212. The first button 2211 is externally mounted on the housing assembly 1 and covers the switch trigger surface of the first switch body 2212.

[0084] In the portable alarm device 100 provided in this embodiment of the present invention, the first switch body 2212 is electrically connected to the control circuit board 41 when closed, and the first switch body 2212 can be closed or opened by pressing the first button 2211; when the first switch body 2212 is closed, the energy storage component 42 drives the buzzer module 223 to work.

[0085] Understandably, by setting the first switch component 221 in this embodiment, the buzzer module 223 can not only trigger the portable alarm device 100 to work when the stretching component 3 is separated from the touch button 21, but also can be activated by manually pressing the first button 2211 to emit a buzzer alarm, thereby improving the practicality and versatility of the portable alarm device 100.

[0086] Specifically, the positions of the first button 2211 and the first switch body 2212 in the portable alarm device 100 can be adaptively adjusted according to the positions of other modules. It is only necessary to ensure that the first button 2211 is stacked on the first switch body 2212 and that the first switch body 2212 is electrically connected to the control circuit board 41 when closed.

[0087] In this embodiment of the present invention, a first mounting port is provided in the upper housing 11, and the first button 2211 is inserted into the inner wall surface of the upper housing 11 for fixation; the first switch body 2212 is mounted on the control circuit board 41 by welding, and the first button 2211 can be pressed to touch the switch trigger surface of the first switch body 2212, thereby controlling the opening and closing of the first switch body 2212.

[0088] Please see Figure 9In some embodiments, a first buffer 411 is provided between the first button 2211 and the control circuit board 41, and a second buffer 421 is provided between the upper housing 11 and the energy storage component 42.

[0089] In the portable alarm device 100 provided in this embodiment of the present invention, by providing buffers between the first button 2211 and the control circuit board 41, and between the upper housing 11 and the energy storage component 42, the control circuit board 41 and the energy storage component 42 can be buffered and shock-reduced when the user carries the portable alarm device 100, so as to avoid damage to the circuit components such as the control circuit board 41 and the energy storage component 42, thereby extending the service life of the portable alarm device 100.

[0090] Specifically, a first buffer 411 is provided between the first button 2211 and the control circuit board 41. On the one hand, it can buffer and dampen the control circuit board 41, preventing excessive pressure on the first button 2211 and damage to the control circuit board 41 when the user presses the first button 2211 to control the opening and closing of the buzzer module 223. On the other hand, it can provide the user with a damping sensation when the first button 2211 is pressed to close or open the first switch body 2212. The first buffer 411 can make the first button 2211 achieve a slow rebound and reset after being pressed, so that the user can press it again, thus improving the user experience.

[0091] Understandably, in this embodiment, the energy storage component 42 is mounted on the control circuit board 41, and the energy storage component 42 is located in the middle section of the overall internal structure of the portable alarm device 100. A second buffer component 421 is provided between the upper housing 11 and the energy storage component 42. This serves two purposes: firstly, it provides cushioning and shock absorption for the energy storage component 42 and the control circuit board 41, preventing damage to the energy storage component 42 and the control circuit board 41 from severe bumps and shaking when the user carries the portable alarm device 100; secondly, it prevents the energy storage component 42 mounted on the control circuit board 41 from becoming loose and affecting the alarm effect, thus ensuring the stability of the internal structure of the portable alarm device 100.

[0092] It should be noted that, as a preferred embodiment of this utility model, the first buffer 411 and the second buffer 421 are made of foam. It can be understood that the material and size of the first buffer 411 and the second buffer 421 can be adjusted according to actual needs. The choice of buffer material only needs to meet the buffering and shock absorption effect, and the size of the buffer is generally set according to the size of the portable alarm device 100. The above description is only one embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions and improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0093] Please continue reading. Figure 6 , Figure 7 and Figure 8 The housing assembly 1 also includes a transparent outer shell 13, which is installed on the side of the upper housing 11 and the lower housing 12 away from the opening 20; the warning assembly 2 also includes a light-emitting assembly 23, which includes a light-emitting element 231 and a light-shielding element 232. The light-emitting element 231 is installed on the control circuit board 41 and is electrically connected to the control circuit board 41. The light-shielding element 232 is sleeved on the end of the control circuit board 41 near the light-emitting element 231. The light-emitting element 231 is disposed between the light-shielding element 232 and the transparent outer shell 13.

[0094] In the portable alarm device 100 provided in this embodiment, the light-emitting element 231 can be used to emit different types of light, such as illumination, ambient light, and strobe light. The light-emitting element 231 and the energy storage element 42 are located on the same side of the control circuit board 41. The light emitted by the light-emitting element 231 shines to the outside through the transparent shell 13, making it suitable for various emergency situations. In this embodiment, the light-emitting element 231 is specifically an LED lamp bead, which is mounted on the control circuit board 41 by soldering.

[0095] In this embodiment, the light-emitting element 231 is disposed on one end of the control circuit board 41 near the transparent shell 13, and the light-emitting elements 231 are distributed in a ring around the edge of the control circuit board 41. Specifically, each light-emitting element 231 on the control circuit board 41 is equidistantly distributed to make the light emitted by the light-emitting element 231 more uniform, so that the light can be smoothly transitioned when emitting ambient light and avoid visual judder. In addition, the equidistantly distributed light-emitting elements 231 can reduce signal path differences and also prevent local overheating of the control circuit board 41, thereby improving the heat dissipation efficiency inside the portable alarm device 100.

[0096] Understandably, the light shield 232 is located on the side of the light-emitting element 231 away from the transparent housing 13. The light shield 232 is used to block the light source that shines on the control circuit board 41 when the light-emitting element 231 is working. Through this design, the control circuit board 41 and the energy storage element 42 and other circuit components inside the portable alarm device 100 can be protected.

[0097] It should be noted that without the light-shielding component 232, the light emitted by the light-emitting component 231 may shine on the energy storage component 42 and the control circuit board 41, potentially causing high temperatures inside the portable alarm device 100. This high temperature could raise the temperature of the control circuit board 41, causing the electronic components on the control circuit board 41 to expand, and even leading to loosening or detachment of solder joints. Therefore, this embodiment uses the light-shielding component 232 to protect the circuit components, preventing damage to the internal circuit components of the portable alarm device 100 and extending its service life.

[0098] Furthermore, the light-emitting component 23 also includes a second switch component 233, which includes a second button 2331 and a second switch body 2332. The second button 2331 is exposed and mounted on the housing component 1, and the second button 2331 covers the switch trigger surface of the second switch body 2332.

[0099] It should be further noted that the second button 2331 in this embodiment is located on the side of the housing assembly 1, specifically on the side of the upper housing 11 and the lower housing 12 near the transparent outer shell 13; compared to the second button 2331, the first button 2211 is located on the top of the upper housing 11, that is, the first button 2211 is located facing the control circuit board 41.

[0100] In the portable alarm device 100 provided in this embodiment of the present invention, the second switch body 2332 is electrically connected to the control circuit board 41 when closed, and the second switch body 2332 can be closed or opened by pressing the second button 2331; when the second switch body 2332 is closed, the energy storage component 42 drives the light-emitting component 231 to work.

[0101] Understandably, by setting the second switch assembly 233 in this embodiment, the light-emitting element 231 can not only trigger the portable alarm device 100 to work when the stretching assembly 3 is separated from the touch button 21, but also be activated by manually pressing the second button 2331. This design allows the user to receive illumination in low light conditions or when calling for help, further improving the practicality and versatility of the portable alarm device 100.

[0102] Specifically, the positions of the second button 2331 and the second switch body 2332 in the portable alarm device 100 can be adaptively adjusted according to the positions of other modules. It is only necessary to ensure that the second button 2331 is stacked on the second switch body 2332 and that the second switch body 2332 is electrically connected to the control circuit board 41 when closed.

[0103] In this embodiment of the present invention, a second mounting port is provided between the upper housing 11 and the lower housing 12. When assembling the housing component 1, the second button 2331 is installed between the upper housing 11 and the lower housing 12 through the mounting port. The second button 2331 and the lower housing 12 are fixed by a snap fastener. The second switch body 2332 is installed on the control circuit board 41 by welding. By pressing the second button 2331, the second button 2331 can touch the switch trigger surface of the second switch body 2332, thereby controlling the opening and closing of the second switch body 2332.

[0104] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
