Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, specifically a flashlight that integrates zoom and floodlight functions. Background Technology

[0002] A zoom flashlight is a type of flashlight that allows users to change the focusing range of the beam by adjusting the lens or the position of the light source. Users can use the focused beam mode for long-distance illumination: the beam is concentrated and the range is long, suitable for long-distance lighting such as search and outdoor adventures. Alternatively, they can use the floodlight mode for short-distance illumination: the light is diffused and the coverage is wide, suitable for close-range, wide-area lighting such as camping and repairs.

[0003] Existing zoom flashlights utilize two or more light source boards to achieve the functions of a spotlight and a camping light, respectively. This increases the cost of the product and makes it prone to defects.

[0004] From an operational perspective, adding a light source also requires adding a separate control unit, which is detrimental to both circuit design and ease of use.

[0005] Therefore, we propose a flashlight that integrates zoom and floodlight functions to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a flashlight that integrates zoom and floodlight functions to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flashlight integrating zoom and floodlight functions, comprising: a lens, a light-shielding ring, a handle, and a battery cover, wherein a battery is disposed inside the handle, the battery cover is fixedly installed at the rear end of the handle, a connector is fixedly installed at the front end of the handle, a circuit board is disposed inside the connector, and the circuit board is electrically connected to the battery inside the handle.

[0008] The light source base is fixedly installed at the front end of the connector, and the light source is fixedly installed at the front end of the light source base. The circuit board is electrically connected to the light source.

[0009] A diffusion ring is slidably fitted around the base of the light source, and a light-shielding ring is movably fitted around the diffusion ring. A lens is fixedly installed at the front end of the diffusion ring, and the lens limits the front end of the light-shielding ring. A light-shielding cover is detachably installed on the lens.

[0010] The diffusion ring is made of a light-transmitting material.

[0011] Preferably, a temperature control switch and a charging interface are installed on the circuit board.

[0012] Preferably, a bottom limiting protrusion is integrally provided on the outer surface of the connection between the light source base and the connecting seat, and a limiting inner protrusion is integrally provided on the end of the light shielding ring near the handle. The limiting inner protrusion is in contact with the bottom limiting protrusion and the limiting inner protrusion is in contact with the diffusion ring, thereby limiting the bottom of the light shielding ring and the diffusion ring.

[0013] Preferably, the end of the light source base away from the connecting seat is integrally provided with a top limiting protrusion, and the end of the diffusion ring near the limiting inner protrusion is integrally provided with an inward protrusion, and the top limiting protrusion limits the top of the protrusion of the diffusion ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By simplifying the structure of the flashlight's light source and light guide, sliding the light-shielding ring and diffuser ring, and adjusting the distance between the lens and the light source, the zoom function of a single-light-source flashlight can be achieved, as well as the floodlight function of a single-light-source flashlight. This improves the quality, safety, and convenience of floodlights, reduces material and labor costs in the product, and extends its service life. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a flashlight that integrates zoom and floodlight, including: lens 1, light shield 2, handle 3 and battery cover 7. A battery is installed inside the handle 3. The battery cover 7 is threadedly installed at the rear end of the handle 3. A connector 11 is threadedly installed at the front end of the handle 3. A circuit board 8 is installed inside the connector 11. The circuit board 8 is electrically connected to the battery inside the handle 3.

[0025] The connector 11 is threaded onto the front end of the light source base 5, and the light source 9 is fixedly mounted on the front end of the light source base 5. The circuit board 8 is electrically connected to the light source 9.

[0026] A switch temperature control button 4 and a charging interface 10 are installed on the circuit board 8. The switch temperature control button 4 is used to control the opening and closing of the circuit between the circuit board 8 and the light source 9 and the current magnitude. The charging interface 10 is used to charge the battery in the handle 3.

[0027] A diffuser ring 6 is slidably fitted onto the outside of the light source base 5, and a light-shielding ring 2 is fitted onto the outside of the diffuser ring 6. A lens 1 is threadedly installed at the front end of the diffuser ring 6, and the lens 1 limits the front end of the light-shielding ring 2.

[0028] A bottom limiting protrusion ring 51 is integrally provided on the outer surface of the connection between the light source base 5 and the connecting seat 11. A limiting inner protrusion ring 21 is integrally provided on one end of the light shield ring 2 near the handle 3. The limiting inner protrusion ring 21 abuts against the bottom limiting protrusion ring 51 to limit the light shield ring 2.

[0029] The limiting inner convex ring 21 abuts against the diffuser ring 6, thereby limiting the diffuser ring 6. When the diffuser ring 6 slides relative to the light source base 5, the diffuser ring 6 is limited.

[0030] The light source base 5 is integrally provided with a top limiting protrusion 52 at the end away from the connecting seat 11, and the diffuser ring 6 is integrally provided with an inward protrusion at the end near the limiting inner protrusion 21. When the protrusion 6 slides to the front end, it is limited by the top limiting protrusion 52, thereby realizing the limitation of the back and forth sliding of the diffuser ring 6.

[0031] A light-shielding cover is installed on lens 1, and the diffuser ring 6 is made of light-transmitting material. When the diffuser ring 6 is exposed, a floodlight effect is achieved.

[0032] Working principle: The battery in the handle 3 powers the circuit board 8 in the connector 11. The circuit board 8 performs functions such as light emission, temperature change, and charging through the switch temperature control button 4 and charging interface 10. The circuit board 8 drives the light source 9 to emit light, and the light beam is provided to the environment after passing through the lens 1.

[0033] With the flashlight powered on and illuminated, keep the light-shielding ring 2 and the diffuser ring 6 overlapping. Simultaneously slide the light-shielding ring 2 and the diffuser ring 6 to adjust the distance between the lens 1 and the light source 9, thereby adjusting the focal length and focusing the light. When the light-shielding ring 2 and the diffuser ring 6 are at the top limit, the focusing angle is the smallest, the light spot is the smallest and brightest, and the light range is the longest. When the light-shielding ring 2 and the diffuser ring 6 are at the bottom limit, the focusing angle is the largest, the light spot is the largest and dimmest, and the light range is the shortest, making it very suitable for activities such as search and rescue and outdoor adventure.

[0034] With the flashlight powered on, push the light-shielding ring 2 and the diffuser ring 6 together to the top of the light source base 5. Then pull the light-shielding ring 2 to the bottom of the light source base 5, exposing the diffuser ring 6. At this time, light is transmitted through the diffuser ring 6, allowing the light to shine in all directions, thus achieving the effect of a floodlight. In floodlight mode, cover the lens 1 with the cap to enhance the light from the diffuser ring 6 and achieve a floodlight illumination effect, which is very suitable for close-range activities such as camping, repairs, and studying.
