Description

Technical Field

[0001] This utility model belongs to the field of headlamp technology, and in particular relates to a headlamp with good breathability. Background Technology

[0002] Headlamps, as an extremely important portable lighting tool, are widely used in many scenarios such as outdoor exploration, night running, and industrial maintenance. In these scenarios, users often need to wear headlamps for extended periods of time, thus placing high demands on the comfort of wearing headlamps.

[0003] A Chinese patent application with publication number CN210291468U discloses a novel, simple, and detachable headlamp structure, including a lamp holder connected to a headband and a lamp body mounted on the lamp holder. The lamp holder and lamp body are rotatably connected. A half-gear component is provided on the bottom back of the lamp body, and a corresponding locking component is provided on the front side of the lamp holder, which is embedded in the half-gear component. The lamp body includes a back plate and a front shell, with the bottom of the back plate and the front shell connected by a pivot. The top of the front shell and the top of the back plate are snapped together. The overall structure has a simple design, and the lamp body is adjustable and detachable.

[0004] This headlamp structure has solved the problem of headlamp adjustability and detachability to some extent. However, during long-term use, especially during high-intensity outdoor activities or continuous work in industrial environments, the human head will generate a lot of heat and sweat. Due to the lack of active ventilation facilities, the heat and sweat cannot be discharged in time, causing heat to easily accumulate in the area where the headband contacts the head and the area where the lamp body contacts the forehead, resulting in a stuffy feeling. This not only seriously affects the wearing comfort, but also lacks a quick-release structure between the headband and the lamp body so that the headband can be cleaned quickly when needed.

[0005] To address these issues, we have developed a headlamp with good ventilation. Utility Model Content

[0006] The purpose of this invention is to provide a headlamp with good breathability. By combining a ventilation mechanism and a quick-release mechanism, it solves the problems of existing headlamps lacking active ventilation facilities, heat and sweat not being able to be discharged in time, and lacking a quick-release structure between the headband and the lamp body.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a headlamp with good ventilation, comprising a lamp body, a ventilation mechanism fixedly connected to one side of the lamp body, a quick-release mechanism provided on one side of the lamp body, and a housing. One side of the housing is fixedly connected to the lamp body, and an air inlet is provided on the top of the housing. Heat dissipation grooves are provided on both sides of the surface of the housing. A fan is fixedly connected to the inner cavity of the housing. A protective grille is fixedly connected to one side of the housing, and a flexible protective ring is fixedly connected to the surface of the protective grille. Positioning grooves are provided on both sides of the housing. The housing not only protects the internal fan but also guides airflow along a preset path, preventing airflow dispersion and ensuring ventilation efficiency. The protective grille uses a mesh structure to effectively block external dust and hair from entering the inner cavity of the housing. The flexible protective ring gently contacts the user's scalp or hair when the headlamp is worn. The flexible protective ring avoids friction or pressure from the hard edges of the protective grille, improving wearing comfort. It also fills the tiny gaps between the protective grille and the head, reducing airflow leakage. When the fan starts, outside air is drawn into the inner cavity of the outer shell through the air intake at the top of the shell by the fan's suction. The air entering the inner cavity forms a stable airflow under the push of the fan. Part of the airflow flows along the inner cavity of the shell and is discharged through the heat dissipation slots on both sides of the shell, carrying away the heat from inside the shell and the lamp body. The other part of the airflow passes through the protective grille and, guided by the flexible protective ring, acts directly on the area where the user's head contacts the headlamp. It can quickly remove the heat generated by the head and the moisture formed by the evaporation of sweat, effectively reducing the temperature and humidity of the head contact area, avoiding stuffiness, and improving the comfort of wearing the headlamp.

[0009] The present invention is further configured such that the quick-release mechanism includes a fixing strap, and positioning blocks are provided on both sides of the fixing strap. The positioning blocks are adapted to positioning grooves. Limiting posts are fixedly connected to the top and bottom of the inner cavity of the positioning blocks. A spring is sleeved on the surface of the limiting post. A movable plate is sleeved on the surface of the limiting post and on one side of the spring. A positioning post is fixedly connected to one side of the movable plate, and a pressing block is fixedly connected to the other side of the movable plate. The limiting post guides the spring and the movable plate, preventing the movable plate from shifting during movement and ensuring the stability of the structure. The elastic reset function of the spring allows the movable plate to automatically rebound and lock the positioning post after the pressing block is pressed, completing the fixation without additional operation and simplifying the assembly process. The extension and retraction of the positioning post can be controlled by pressing the pressing block by hand, realizing the separation of the quick-release mechanism and the ventilation mechanism.

[0010] The present invention is further configured such that a connecting ring is fixedly connected to one side of the positioning block, and the fixing strap is sleeved in the inner cavity of the connecting ring. The connecting ring provides a clear mounting carrier for the fixing strap. The way in which the fixing strap is sleeved in the inner cavity of the connecting ring can prevent the fixing strap from falling off or shifting during use, thereby ensuring the overall stability of the headlamp when worn.

[0011] The present invention is further configured such that the fixing strap is an elastic band, and a flexible pad is fixedly connected to one side of the surface of the fixing strap. The fixing strap is made of elastic band material to ensure that the headlamp always fits the head in motion and work scenarios, ensuring lighting stability. The flexible pad further improves wearing comfort.

[0012] The present invention is further provided that a control switch is provided on the top of the lamp body and a transparent protective cover is provided on one side of the lamp body. The control switch can control the opening and closing of the lamp body, and the transparent protective cover can protect the lamp body.

[0013] The present invention is further configured such that a charging hole is provided at the bottom of the lamp body and an air outlet is provided at the bottom of the outer shell. The user can directly connect the charging hole to power the headlamp through the charging cable, and the air outlet can further improve the airflow circulation path.

[0014] The present invention is further configured such that the heat dissipation slots are equally spaced, and the heat dissipation slots ensure that the airflow flows evenly on both sides of the outer shell, avoiding the situation where local airflow is concentrated and local airflow is absent due to uneven distribution of heat dissipation slots.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model has a ventilation mechanism on one side of the lamp body. When the fan is running, the outside air enters the inner cavity of the outer shell quickly through the air inlet. After being accelerated by the fan, it is evenly blown to the area around the head through the heat dissipation groove, which removes heat and sweat. This achieves active heat dissipation and ventilation. Compared with traditional headlamps that rely solely on natural ventilation, its breathability is greatly improved, which can effectively reduce the feeling of stuffiness on the head and improve wearing comfort. Even in hot environments or long-term high-intensity use scenarios, it can maintain good breathability.

[0017] 2. This utility model achieves quick disassembly and installation between the headband and the lamp body through a quick-release mechanism. When the headband needs to be removed, the user only needs to press the button, and the movable plate drives the positioning post to retract, allowing the positioning block to be easily removed from the positioning groove, thereby quickly separating the headband from the lamp body. During installation, the positioning block is aligned with the positioning groove and inserted. The positioning post automatically pops out under the action of the spring and locks into the positioning groove, completing the quick fixation. This greatly facilitates the user's replacement and cleaning of the headband in different scenarios. Attached Figure Description

[0026] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1 Please see Figure 1-6 This utility model is a headlamp with good ventilation, including a lamp body 1. A ventilation mechanism 2 is fixedly connected to one side of the lamp body 1. A quick-release mechanism 3 is provided on one side of the lamp body 1. The ventilation mechanism 2 includes a housing 21. One side of the housing 21 is fixedly connected to the lamp body 1. An air inlet 22 is provided on the top of the housing 21. Heat dissipation grooves 23 are provided on both sides of the surface of the housing 21. A fan 24 is fixedly connected to the inner cavity of the housing 21. A protective grille 25 is fixedly connected to one side of the housing 21. A flexible protective ring 26 is fixedly connected to the surface of the protective grille 25. Positioning grooves 27 are provided on both sides of the housing 21.

[0028] Specifically: the outer shell 21 not only protects the internal fan 24 but also guides airflow along a preset path, preventing airflow dispersion and ensuring ventilation efficiency. The protective grille 25 uses a mesh structure to effectively block external dust and hair from entering the inner cavity of the outer shell 21. The flexible protective ring 26 gently contacts the user's scalp or hair when the headlamp is worn, preventing the hard edges of the protective grille 25 from causing friction or pressure, thus improving wearing comfort. The flexible protective ring 26 also fills the tiny gaps between the protective grille 25 and the head, reducing airflow leakage. When the fan 24 is activated, outside air is drawn in by the suction of the fan 24 through... The air intake 22 at the top of the outer shell 21 quickly enters the inner cavity of the outer shell 21. The air entering the inner cavity is driven by the fan 24 to form a stable airflow. Part of the airflow flows along the inner cavity of the outer shell 21 and is discharged through the heat dissipation slots 23 on both sides of the outer shell 21, taking away the heat from inside the outer shell 21 and the heat transferred from the lamp body 1 to the outer shell 21. The other part of the airflow passes through the protective grille 25 and, guided by the flexible protective ring 26, acts directly on the area where the user's head contacts the headlamp. It can quickly remove the heat generated by the head and the moisture formed by the evaporation of sweat, effectively reducing the temperature and humidity of the head contact area, avoiding stuffiness, and improving the comfort of wearing the headlamp.

[0029] Example 2 Please see Figure 1-6 Based on Embodiment 1, the quick-release mechanism 3 includes a fixing strap 31, with positioning blocks 32 on both sides of the fixing strap 31. The positioning blocks 32 are adapted to the positioning grooves 27. Limiting posts 33 are fixedly connected to the top and bottom of the inner cavity of the positioning blocks 32. A spring 34 is sleeved on the surface of the limiting posts 33. A movable plate 35 is sleeved on the surface of the limiting posts 33 and on one side of the spring 34. A positioning post 36 is fixedly connected to one side of the movable plate 35. A pressing block 37 is fixedly connected to the other side of the movable plate 35. A connecting ring 4 is fixedly connected to one side of the positioning blocks 32. The fixing strap 31 is sleeved in the inner cavity of the connecting ring 4. The fixing strap 31 is an elastic band. A flexible pad 5 is fixedly connected to one side of the surface of the fixing strap 31. A control switch 6 is provided on the top of the lamp body 1. A transparent protective cover 7 is provided on one side of the lamp body 1. A charging hole 8 is provided at the bottom of the lamp body 1. An air outlet 9 is provided at the bottom of the outer shell 21. The heat dissipation grooves 23 are evenly distributed.

[0030] Specifically: the limiting post 33 guides the spring 34 and the movable plate 35, preventing the movable plate 35 from shifting during movement and ensuring the stability of the structure. The elastic reset function of the spring 34 allows the movable plate 35 to automatically spring back and lock the positioning post 36 after pressing the button 37, completing the fixation without additional operation and simplifying the assembly process. The extension and retraction of the positioning post 36 can be controlled by pressing the button 37, realizing the separation of the quick-release mechanism 3 and the ventilation mechanism 2. The connecting ring 4 provides a clear mounting carrier for the fixing strap 31. The way the fixing strap 31 is sleeved in the inner cavity of the connecting ring 4 can avoid the fixing strap 31 during use. In case of detachment or displacement during the process, the headlamp is made of elastic material to ensure overall stability when worn. The fixing strap 31 ensures that the headlamp always fits the head during movement and work, ensuring lighting stability. The flexible pad 5 further improves wearing comfort. The control switch 6 can control the opening and closing of the lamp body 1. The transparent protective cover 7 can protect the lamp body 1. The user can directly connect the charging port 8 to power the headlamp through the charging cable. The air outlet 9 can further improve the airflow circulation path. The heat dissipation groove 23 ensures that the airflow flows evenly on both sides of the outer shell 21, avoiding the situation where the airflow is concentrated in some areas and there is no airflow in some areas due to the uneven distribution of the heat dissipation groove 23.

[0031] The working principle of this utility model is as follows: by starting the fan 24, the fan 24 draws outside air into the inner cavity of the outer shell 21 through the air inlet 22. Under the continuous push of the fan 24, a stable airflow is formed and divided into two paths to achieve different functions. Part of the airflow diffuses to both sides along the inner cavity of the outer shell 21 and is finally discharged through the heat dissipation grooves 23 on both sides of the surface of the outer shell 21. The airflow can pass evenly through each heat dissipation groove 23 to achieve the ventilation effect. The other part of the airflow flows directly to the protective grille 25 to continuously cool the head.

[0032] When it is necessary to remove the fixing strap 31, press the button 37 on the outside of the positioning block 32 by hand. The button 37 drives the movable plate 35 to move along the limiting post 33 into the inner cavity. While the movable plate 35 compresses the spring 34, it drives the positioning post 36 to retract into the inner cavity of the positioning block 32, releasing the locking state between the positioning post 36 and the positioning groove 27. Simply pull the positioning block 32 outward to remove the positioning block 32 from the positioning groove 27, realizing the quick separation of the fixing strap 31 from the lamp body 1.

[0033] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
