[0021] The present application provides a flashlight 1000.

[0022] Please refer to Figures 1 to 4 In an embodiment of the present application, the flashlight 1000 includes a barrel 1, a light-emitting assembly, a function compartment 2, and a striking assembly; the light-emitting assembly is arranged at one end of the barrel 1; the function compartment 2 is detachably arranged at the end of the barrel 1 away from the light-emitting assembly; and the striking assembly is arranged in the function compartment 2.

[0023] The barrel 1 is usually a long cylindrical structure, and its interior is used to accommodate a battery. The barrel wall can be provided with a switch and other control circuit. The barrel 1 constitutes the main structure and holding part of the flashlight 1000.

[0024] The light-emitting assembly is arranged at one end of the barrel 1. The light-emitting assembly usually includes an LED lamp bead, a reflecting cup, a lens, etc., and is the core part of the flashlight 1000 to realize the lighting function, which is powered by the battery in the barrel 1 to realize lighting.

[0025] The functional compartment 2 is detachably connected to the end of the barrel body 1 away from the light-emitting assembly (i.e., the tail end of the barrel body 1). The functional compartment 2 is a separate component with an internal cavity. It can be connected to the barrel body 1 in a threaded connection, a snap connection, a magnetic attraction connection, etc.

[0026] The ignition assembly is arranged inside the functional compartment 2. The ignition assembly can be a standard combination of a magnesium rod 3 and a scraper. The functional compartment 2 provides a dedicated accommodation and protection space for the ignition assembly.

[0027] In the technical solution of the present application, the ignition assembly is arranged in the functional compartment 2, which facilitates carrying and use, avoids the risk of scattered storage and loss of tools, and realizes the modularity of the ignition function. Users can choose to install or remove the entire functional compartment 2, so that the flashlight 1000 can be flexibly switched between the standard lighting mode and the multi-functional survival mode. At the same time, the functional compartment 2 provides a solid and dedicated storage space for the ignition assembly, avoiding loss and providing comprehensive protection against moisture, dust, and impact, ensuring its availability in harsh environments at all times.

[0028] Specifically, in an embodiment of the present application, please refer to Figure 2 , one end of the functional compartment 2 is provided with a threaded connection part 201, and the barrel body 1 is provided with a threaded matching part 101. The threaded connection part 201 and the threaded matching part 101 are threadedly connected. The threaded connection part 201 can be an external thread machined on the end of the functional compartment 2, and the threaded matching part 101 is an internal thread machined on the inside of the tail end of the barrel body 1. By rotating the functional compartment 2, the threaded connection part 201 on it and the threaded matching part 101 on the barrel body 1 are screwed together, thereby achieving a firm threaded connection between the two. Among all common detachable connection methods, threaded connection can provide the strongest tensile strength and torsional strength. It can ensure that the functional compartment 2 will not separate from the barrel body 1 even in the case of violent shaking, falling or accidental pulling, greatly improving the overall reliability and durability of the product. After the functional compartment 2 and the barrel body 1 are tightened, the threaded connection does not have any moving gap, and the functional compartment 2 and the barrel body 1 are tightly combined as a rigid whole. This is crucial for holding the feel, operating stability, and preventing loosening. In other embodiments, the functional compartment 2 can be detachably connected to the barrel body 1 through magnetic attraction or clamping, etc.

[0029] To ensure sealing performance, in an embodiment of the present application, the end of the functional compartment 2 is provided with an O-ring groove and an O-ring is installed. In this way, after the functional compartment 2 is connected to the barrel body 1, the O-ring will be compressed, thereby improving the sealing performance. Even if a small amount of water seeps in along the threads, it will be blocked by the O-ring.

[0030] Further, in an embodiment of the present application, please refer to Figure 3 andFigure 4 The lighting device 1000 further comprises a magnesium rod 3 and an extension rod 4. The magnesium rod 3 is arranged in the functional compartment 2. The extension rod 4 is formed with a socket for limiting insertion of the magnesium rod 3. A scraping piece for scraping the magnesium rod 3 can also be arranged in the functional compartment 2. The extension rod 4 is usually made of metal or high-strength engineering plastic and is formed at one end with a socket which is precisely matched in size with the diameter of the magnesium rod 3 for limiting insertion of the end of the magnesium rod 3. That is, the magnesium rod 3 can be tightly inserted and fixed in the socket so that the extension rod 4 and the magnesium rod 3 are combined into an integral operating rod. Due to the size limitation of the functional compartment 2, the magnesium rod 3 directly arranged in the functional compartment 2 is short in length, and it is difficult to hold the short magnesium rod 3, especially in cold, humid or gloved conditions, the operator's fingers are very easy to slip and hit the scraping piece to cause injury. The extension rod 4 effectively increases the length of the force arm, providing a safe, spacious and stable holding position for the user, which makes the scraping action of the magnesium rod 3 more labor-saving and more accurate. The split insertion design allows the magnesium rod 3 and the extension rod 4 to be arranged in a linear and compact manner in the functional compartment 2, which saves more space compared with the integral magnesium rod 3 which needs a thick handle, and helps to design a smaller functional compartment 2.

[0031] Further, in an embodiment of the present application, referring to Figure 3 The lighting device 1000 further comprises an elastic seat 5 arranged in the functional compartment 2. The elastic seat 5 is formed with a receiving groove in which the lighting device 1000 is arranged. Specifically, the receiving groove can accommodate the magnesium rod 3 and the extension rod 4 of the lighting device 1000, or the receiving groove can be divided into two receiving grooves to accommodate the magnesium rod 3 and the extension rod 4 respectively. Through the receiving groove, the magnesium rod 3 and the extension rod 4 can be fixed in the functional compartment 2 and will not easily shake. The elastic seat 5 is made of elastic materials such as PU foam or rubber.

[0032] Specifically, in an embodiment of the present application, the functional compartment 2 comprises a shell and a cover, the shell is detachably connected with the barrel 1, the cover is arranged at one end of the shell away from the barrel 1, and the cover and the shell jointly form a containing compartment, and the ignition assembly is arranged in the containing compartment. The shell is the main structure of the functional compartment 2, and is detachably connected with the barrel 1. The shell constitutes the main part of the containing space. The cover is arranged at one end of the shell away from the barrel 1. The cover is connected with the shell by means of threads, buckles or hinges. When the cover is combined with the shell, the cover and the shell jointly form the containing compartment. The containing compartment is a closed cavity for storing and protecting the internal items, and the ignition assembly is arranged in the containing compartment. That is, the functional compartment 2 is a closable sealed container, and the user can open the cover at any time to easily take, place, check or replace the ignition assembly in the containing compartment. Meanwhile, the sealed containing compartment formed by the shell and the cover provides important protection for the internal ignition assembly against moisture, dust and foreign matter, and ensures that the key components will not be damp and invalid or blocked in a harsh environment. The containing compartment can also reserve a standardized space for storing other miniature survival tools, such as fish hooks, sewing needles and water purification tablets, thereby greatly enhancing the expansion potential of the functional compartment 2.

[0033] Specifically, in an embodiment of the present application, the flashlight 1000 further comprises a reflector arranged on the inner wall of the cover facing the shell. The reflector is a piece of metal sheet precisely polished or coated, or a glass / plastic sheet with a high-reflectivity film attached to the surface. In a sunny day, the signal flash reflected by the sunlight and the reflector has a long effective transmission distance, and greatly improves the probability of being discovered by a faraway search plane or vehicle in a field rescue. The reflector is arranged on the inner wall of the cover facing the shell by means of adhesion, buckling or ring pressing. That is, when the cover is in a closed state to cover the containing compartment, the reflector is hidden and protected inside the cover; when the user opens the cover to prepare to use the ignition assembly below, the reflector is exposed and in a usable state. When the cover is closed, the reflector is tightly stored in the containing compartment, and the mirror surface is completely isolated from the external environment, thereby avoiding being scratched, worn, oxidized, contaminated or corroded, and ensuring that the reflectivity is always in the best state.

[0034] In an embodiment, the functional compartment 2 is a cylindrical structure with one end open, and the functional compartment 2 and one end of the barrel 1 jointly form a sealed containing space, which can provide important protection for the internal ignition assembly against moisture, dust and foreign matter, and make the overall size of the functional compartment 2 more compact.

[0035] Further, in an embodiment of the present application, please refer to Figure 2 and Figure 3, the recess is formed on the outer surface of the functional compartment 2 which is originally underutilized. The recess provides a mounting position for the compass module 6 without increasing the overall size or adding independent components. The compass module 6 is shaped to match the recess. The compass module 6 is stably embedded in the recess by interference fit, adhesion or screw fastening, so that its surface is flush with or slightly protrudes from the outer surface of the cover, facilitating observation. At the same time, the side wall of the recess can to some extent cushion and protect the glass surface cover of the compass module 6, preventing it from being directly rubbed or slightly impacted. The compass module 6 is located on the outer surface of the functional compartment 2, which is the end of the flashlight 1000 and one of the positions for easy observation. The user can instantly obtain direction information by glancing at the tail of the flashlight 1000 without any operation. By integrating the compass module 6 in an "embedded" manner, the practical value of the flashlight 1000 is greatly improved.

[0036] Further, in an embodiment of the present application, the compass module 6 includes a scale part and a pointer part, both of which have a luminous coating. Specifically, on the dial of the compass, the scale lines indicating directions, the characters (such as N, S, E, W) and the magnetic needle itself are coated or filled with high-performance light-storing luminous material during the manufacturing process. The luminous coating refers to a special fluorescent or phosphorescent material that can absorb and store external light energy and emit visible light in a dark environment. By setting the luminous coating, the user can clearly read the direction whether at night or in a dimly lit scene, expanding the use scenarios and time range of the product. And the user only needs to expose the luminous material to light during the day or when using the flashlight 1000 to absorb and store light energy, so as to obtain clear display for a long time in the subsequent darkness.

[0037] To increase the survival ability, in an embodiment of the present application, please refer to Figure 2 and Figure 3 The flashlight 1000 further includes a whistle 7, which is arranged in the functional compartment 2. The whistle 7 is placed at a specific position in the functional compartment 2, usually beside the fire-making assembly. The whistle 7 is a standard high-frequency survival whistle, which produces a specific high-frequency sound with long transmission distance, strong penetration and less physical effort than human voice, providing an efficient acoustic rescue means in addition to the smoke signal generated by the fire-making assembly. And the whistle 7 is stored in the functional compartment 2, solving the problem of easy loss or forgetfulness of the independent whistle 7, complying with the integrated design principle, and the functional compartment 2 also provides the whistle 7 with dustproof and moistureproof protection at the same level as the fire-making assembly, ensuring its airway unobstructed and ready for use at any time.

[0038] Further, in an embodiment of the present application, the function compartment 2 is formed with a resonance cavity having an air inlet and an air outlet. The function compartment 2 is specially designed to form a resonance cavity inside. The resonance cavity is a precisely formed hollow cavity, and the resonance cavity has an air inlet and an air outlet, which are respectively connected with the outside. When the airflow enters from the air inlet, the high-speed vibration and resonance are generated in the resonance cavity, and then the airflow is discharged from the air outlet, so that the whistle sound is emitted. Thus, the entity structure of the function compartment 2 is directly manufactured into a high-efficiency whistle.

[0039] In the embodiment, the inner cavity of the function compartment 2 is divided into two parts, one part is a containing compartment for accommodating the ignition assembly, and the other part is a resonance cavity for sound generation. Thus, the resonance cavity can be designed and optimized as a pure acoustic element, and is not affected by the storage condition of the items in the containing compartment, so that the best whistle loudness and frequency are achieved. Meanwhile, a removable whistle 7 can be placed in the containing compartment. The air inlet can be arranged on the side wall of the function compartment 2, so that the lips can be naturally attached to the side wall of the function compartment 2 when blowing, and the airflow is easy to be aligned. At this time, the air outlet is also arranged on the side wall of the function compartment 2, and is arranged at an angle of 90° with the air inlet, so that the airflow direction is changed greatly, which is beneficial to form stronger vortex and resonance in the resonance cavity, and generally produces louder whistle sound. Meanwhile, a rotatable or sliding dustproof cover can be arranged, and the air inlet and the air outlet can be physically shielded by the dustproof cover when not in use, so as to avoid the entry of foreign matters such as rainwater and dust from the outside into the resonance cavity, and affect the normal use.

[0040] Specifically, in an embodiment of the present application, please refer to Figure 1 The flashlight 1000 further includes a connecting block 8 and a hanging rope 9. The connecting block 8 is arranged on one side of the function compartment 2, and the connecting block 8 is formed with a through hole. The hanging rope 9 is arranged in the through hole. The connecting block 8 is an independent component, which is fixedly arranged on one side of the function compartment 2 by welding, screw connection or integral molding with the shell of the function compartment 2. The connecting block 8 is formed with a through hole, which is a through hole penetrating through the body of the connecting block 8, and the inner wall of the through hole is smooth. The hanging rope 9 is a high-strength woven rope (such as nylon rope or umbrella rope), which is arranged in the through hole and fixed by knotting, heat melting to form a rope head or using a metal buckle, so as to form a closed loop or an open loop suspension structure. The user can directly hang the function compartment 2 on the wrist, backpack, waistband or tactical vest through the hanging rope 9, so as to prevent the survival tool from being accidentally dropped and lost during the movement.

[0041] Further, in an embodiment of the present application, please refer to Figure 1The flashlight 1000 further comprises a connecting rope 10, one end of the connecting rope 10 is detachably connected with the barrel 1, and the other end of the connecting rope 10 is detachably connected with the functional compartment 2. Specifically, a special connecting ring, a D-shaped ring or a small strong magnetic buckle can be additionally arranged on the surface of the barrel 1, and used to be connected with one end of the connecting rope 10; and correspondingly, the functional compartment 2 is also connected with the other end of the connecting rope 10 through the same structure. Through the connecting rope 10, the functional compartment 2 is physically connected with the barrel 1, so that no matter whether the functional compartment 2 is accidentally dropped during disassembly for maintenance or the main connection (such as a threaded connection) is accidentally loosened under extreme outdoor conditions, the connecting rope 10 can ensure that the functional compartment 2 is always connected with the barrel 1, thereby avoiding the loss of the functional compartment 2.

[0042] Specifically, in an embodiment of the present application, the functional compartment 2 is embedded with an NFC tag, and the chip and the antenna of the NFC (Near Field Communication) tag are collectively packaged in a small module. The module can be embedded in the plastic or composite material inside the functional compartment 2 during the production process, or firmly pasted in the cavity reserved in the base. The NFC tag is passive, meaning that it does not have a power supply of its own. When it enters the electromagnetic field range of a reading device such as a mobile phone supporting NFC function, it can be activated by induction to obtain energy and transmit the information stored inside to the reading device. Users can use a smart phone application to write their personal key medical information (such as blood type, allergic drugs, major disease history, emergency contact phone) into the NFC tag in advance. When the user is accidentally unable to communicate, rescue personnel only need to use a mobile phone close to the accessory to instantly read these information.

[0043] Further, in an embodiment of the present application, a plurality of scale marks are arranged along the length direction of the barrel 1. These scale marks are processed on the shell of the barrel 1 by engraving, printing or inlaying to form a set of accurate and clear scales. The scale marks usually include metric units (such as centimeters, millimeters) and / or imperial units (such as inches). In addition, to enhance practicality, the starting point (zero scale) of the scale marks can start from the end of the barrel away from the base. Through the scale marks, the barrel 1 itself can be converted into a measuring tool; "along the length direction" means that the scales are arranged along the longest axis of the barrel 1 to provide the maximum effective measurement range; "a plurality of scale marks" means that it is a continuous or discrete scale system with a certain accuracy. When surviving in the wild, the size of plants and the depth of water can be judged by the barrel 1, and in medical emergency, the size of the wound or the swelling area can also be quickly measured.

[0044] The above merely illustrates the embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, within the technical concept of the present application, and based on the content of the present application and the accompanying drawings, are included in the patent protection scope of the present application.
