Description

Technical Field

[0001] This utility model belongs to the field of electronic whistle technology, and in particular to an electronic whistle with a detachable buzzer. Background Technology

[0002] Whistles are widely used in various environments, such as the military, traffic control, and various training settings. However, ordinary whistles require manual blowing to produce sound, while electronic whistles do not. Simply pressing a switch button activates the whistle, reducing the effort required and making them more convenient to use. The main sound-producing component of an electronic whistle is a high-frequency buzzer. High-frequency buzzers produce a high-pitched, bright, and penetrating sound with accurate signal return, primarily used in signal prompts and alarm systems.

[0003] Currently, a novel electronic whistle with a portable alarm has been disclosed on the China Patent Network [Authorization Announcement No.: CN210377720U]. It includes a cylinder body, end blocks connected to both ends of the cylinder body, and a whistle tube. A storage battery is installed inside the cylinder body. Connecting cavities are symmetrically opened at both ends of the cylinder body. A speaker is installed in the middle position inside the end block, and a light plate is fixed inside the end block on one side of the speaker. An alarm light is embedded in the middle position inside the light plate. The user can pull the end block, at which time the locking block is squeezed and retracted under the action of the spring, so that the insertion hole is pulled out along the inside of the slot, thereby realizing the disassembly of the end block from the cylinder body.

[0004] The aforementioned new electronic whistle has the following drawbacks: Electronic whistles are high-frequency products used in traffic control, and traffic police need to frequently use the whistles to direct traffic. The high-frequency buzzer is prone to damage during high-frequency use, requiring replacement. This necessitates removing the end block from the cylinder body. The high-frequency buzzer is connected to the circuit board by soldering wires, requiring the wires connecting the high-frequency buzzer to the circuit board to be disconnected from the circuit board before soldering the wires from the new high-frequency buzzer back onto the circuit board. This makes the replacement of the high-frequency buzzer very cumbersome, generally requiring the electronic whistle to be returned to the factory for repair. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an electronic whistle with a detachable buzzer. The technical problem this invention aims to solve is: how to address the inconvenience of replacing the high-frequency buzzer in existing electronic whistles.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A detachable buzzer electronic whistle includes a body, a lamp tube, and a lamp tube cap. The lamp tube has a front end and a rear end, the rear end of which is connected to the body. A circuit board is disposed inside the body, extending into the lamp tube. An LED light is disposed on the circuit board. The circuit board is characterized in that its front end is positioned near the front end of the lamp tube. A buzzer is fixed inside the lamp tube cap, and a wire is connected to the buzzer. One end of the wire has a male terminal connector. A female terminal connector is disposed at the front end of the circuit board. The male terminal connector is inserted into the female terminal connector. The lamp tube cap is threadedly connected to or snapped into the front end of the lamp tube.

[0008] This structure integrates the lamp cap and buzzer into a single component; the buzzer is integrated inside the lamp cap. During assembly, first, the male terminal of the wire is plugged into the female terminal of the circuit board. This plugging is a snap-fit ​​connection, ensuring the buzzer and circuit board connection remains stable without external force. Then, the lamp cap is screwed or snapped onto the front end of the lamp tube. Since the buzzer is a fragile component, if it fails, the front end of the lamp tube will be open after the cap is removed, as the circuit board is located near the front end of the lamp tube. This allows for easy finger insertion to pull the male terminal out of the female terminal, completely removing the lamp cap. A new lamp cap can then be installed to complete the assembly. With this design, customers can quickly replace damaged buzzers by simply providing them with a few more lamp caps or by shipping lamp caps directly to them. The operation is simple and convenient, eliminating the need to send the electronic whistle back to the factory for repair, thus significantly improving the ease of maintenance for electronic whistles.

[0009] In the aforementioned detachable electronic whistle, a notch is provided at the front end of the circuit board, and the female terminal is disposed within the notch. This structure, by creating a notch at the front end of the circuit board, allows the female terminal to be installed, forming an embedded structure on the circuit board. This facilitates the positioning of the female terminal on the circuit board, preventing it from falling off or wobbling, thus ensuring its installation stability.

[0010] In the aforementioned detachable buzzer electronic whistle, the lamp cap includes a cylindrical housing with open ends. A partition plate is located in the middle of the housing, dividing the interior of the housing into a front cavity and a rear cavity. A cover is provided in the front cavity, and an annular sound amplification cavity is formed between the outer circumferential surface of the cover and the inner circumferential surface of the front cavity. The buzzer is disposed inside the cover. An injection hole is provided in the middle of the partition plate, through which the wire passes. Glue is injected into the cover to encapsulate the buzzer. During assembly, the buzzer is first placed inside the housing, then the housing is fastened to the partition plate, ensuring that the male wires and terminal wires pass through the glue injection hole. Next, glue is injected into the housing through the glue injection hole, filling the interior completely. Once the glue hardens, it encapsulates the buzzer, giving it strong waterproof performance and making it less prone to damage. This structure allows the buzzer and lamp cap to form a single component, facilitating shipping and reducing the buzzer's susceptibility to damage during transportation and storage. Furthermore, after the buzzer operates, the sound is amplified outwards through the sound amplification chamber. The sound amplification chamber facilitates sound diffusion, ensuring a loud sound and providing the electronic whistle with good command functionality.

[0011] In the aforementioned detachable electronic whistle, the front side of the partition plate has at least two positioning sleeves, and the inner surface of the cover has at least two positioning posts. Each positioning post corresponds to one of the positioning sleeves, and each positioning post is inserted into its corresponding positioning sleeve. During assembly, the positioning posts are aligned with the positioning sleeves, and then the cover is fastened to the partition plate. Finally, after applying adhesive, the assembly of the cover and the partition plate is ensured to have good stability and firmness, preventing the cover from easily falling off.

[0012] In the aforementioned detachable buzzer electronic whistle, there is a gap between the rear end face of the housing and the front side of the partition plate. This structure creates a gap between the rear end of the housing and the partition plate, allowing the sound generated by the buzzer to enter the amplification cavity through this gap when the buzzer is activated, and then be transmitted outward through the amplification cavity. The gap prevents the housing from obstructing sound transmission, which helps the electronic whistle to transmit a louder sound and improves its command effect.

[0013] In the aforementioned detachable buzzer electronic whistle, the cover and housing are integrally formed, while the partition plate and housing are separate structures. During assembly of the lamp cap, since the cover and housing are integrally formed, the cover forms an installation cavity. First, the buzzer is placed inside the cover, then the partition plate is inserted into the housing and covers the rear end of the cover. Finally, glue is injected into the cover through the injection hole, thereby fixing the partition plate, cover, and housing together.

[0014] In the aforementioned detachable electronic whistle, the amplification cavity is horn-shaped. The horn-shaped amplification cavity facilitates the outward diffusion of the sound generated by the buzzer.

[0015] In the aforementioned detachable electronic whistle, the front end of the lamp tube extends into the rear cavity, and the front end of the lamp tube is threadedly connected to the inner wall of the rear cavity.

[0016] Compared with the prior art, the detachable buzzer electronic whistle of this utility model has the following advantages: After adopting this design, customers only need to be provided with a few more lamp caps or be directly shipped to them, and they can quickly replace the damaged buzzer themselves. The operation is simple and convenient, and there is no need to send the electronic whistle back to the factory for repair, which significantly improves the convenience of electronic whistle maintenance.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 8As shown, this detachable electronic whistle includes a body 1, a lamp tube 2, and a lamp tube cap 3. The lamp tube 2 has a front end and a rear end, with the rear end connected to the body 1. A circuit board 4 is disposed inside the body 1, extending into the lamp tube 2. An LED light 9 is disposed on the circuit board 4. The front end of the circuit board 4 is positioned near the front end of the lamp tube 2. A buzzer 5 is fixed inside the lamp tube cap 3, and a wire 6 is connected to the buzzer 5. One end of the wire 6 has a male terminal 7. A female terminal 8 is disposed at the front end of the circuit board 4. In this embodiment, a notch 40 is opened at the front end of the circuit board 4, and the female terminal 8 is disposed within the notch 40. The male terminal 7 and the female terminal 8 are inserted into each other, and the lamp tube cap 3 is threadedly connected to or snapped into the front end of the lamp tube 2. In this structure, a battery is installed inside the tube body 1, and the battery is electrically connected to the circuit board 4. The battery powers the circuit board 4, LED light 9, and buzzer 5. A laser emitter is installed on the tube body 1, along with a buzzer button and a laser button. Pressing the buzzer button controls the operation of the buzzer 5 and LED light 9, while pressing the laser button controls the operation of the laser emitter. This structure assembles the lamp cap 3 and buzzer 5 into a single component; that is, the buzzer 5 is integrated within the lamp cap 3. During assembly, the male terminal 7 on the wire 6 is first inserted into the female terminal 8 on the circuit board 4. The insertion of the male terminal 7 and the female terminal 8 is a snap-fit ​​connection, ensuring that they will not detach under no external force, thus guaranteeing the stability of the connection between the buzzer 5 and the circuit board 4. Then, the lamp cap 3 is screwed or snapped onto the front end of the lamp tube 2. Since the buzzer 5 is a fragile component, when it fails, because it is located inside the lamp cap 3, once the lamp cap 3 is removed, the front end of the lamp tube 2 is open. Since the front end of the circuit board 4 is close to the front port of the lamp tube 2 (i.e., the assembly position of the male terminal 7 and female terminal 8 is also near the front port of the lamp tube 2), a finger can easily reach in and pull the male terminal 7 out of the female terminal 8. At this point, the lamp cap 3 can be completely removed from the lamp tube 2, and then a new lamp cap 2 can be installed. With this design, customers only need to be provided with several lamp caps 2 or the lamp caps 2 are shipped directly to them. Customers can then quickly replace the damaged buzzer 5 themselves. The operation is simple and convenient, eliminating the need to return the electronic whistle to the factory for repair, significantly improving the ease of maintenance.

[0030] like Figures 1 to 8As shown, the lamp cap 3 includes a cylindrical housing 30, with open ends. A partition plate 31 is located in the middle of the housing 30, dividing the interior of the housing 30 into a front cavity 32 and a rear cavity 33. The front end of the lamp tube 2 extends into the rear cavity 33 and is threadedly connected to the inner wall of the rear cavity 33. A cover 34 is disposed within the front cavity 32, forming an annular amplification cavity 35 between the outer circumferential surface of the cover 34 and the inner circumferential surface of the front cavity 32. The amplification cavity 35 is horn-shaped. A buzzer 5 is disposed within the cover 34. A glue injection hole 36 is provided in the middle of the partition plate 31, through which the wire 6 passes. Glue is injected into the cover 34 to encapsulate the buzzer 5. During assembly, the buzzer 5 is first placed inside the housing 34, and then the housing 34 is fastened to the partition plate 31, with the wire 6 and the male terminal 7 passing through the glue injection hole 36. Next, glue is injected into the inside of the housing 34 through the glue injection hole 36, filling the inside of the housing 34 completely. After the glue hardens, it encapsulates the buzzer 5, giving it strong waterproof performance and making it less prone to damage. This structure makes the buzzer 5 and the lamp cap 3 form a single component, facilitating shipping and preventing damage to the buzzer 5 during transportation and storage. Secondly, after the buzzer 5 is activated, the sound is emitted outward through the amplification cavity 35. The amplification cavity 35 facilitates the outward diffusion of the buzzer 5's sound, ensuring a loud sound and providing the electronic whistle with good command function.

[0031] like Figure 7 and Figure 8 As shown, the front side of the partition plate 31 has at least two positioning sleeves 37, and the inner surface of the cover 34 has at least two positioning posts 38. Each positioning post 38 corresponds to one positioning sleeve 37, and each positioning post 38 is inserted into its corresponding positioning sleeve 37. During assembly, the positioning posts 38 are aligned with the positioning sleeves 37, and then the cover 34 is fastened onto the partition plate 31. Finally, after applying adhesive, the assembly of the cover 34 and the partition plate 31 is ensured to have good stability and firmness, preventing the cover 34 from easily falling off.

[0032] Example 2

[0033] This embodiment is basically the same as Embodiment 1 above, except that: Figure 9 and Figure 10 As shown, there is a gap between the rear end face of the housing 34 and the front side face of the partition plate 31. This structure creates a gap between the rear end of the housing 34 and the partition plate 31. When the buzzer 5 is activated, the sound generated by the buzzer 5 can enter the amplification cavity 35 through this gap and then be transmitted outward through the amplification cavity 35. The gap ensures that the housing 34 does not obstruct the propagation of sound, which is beneficial for the electronic whistle to transmit a louder sound and improve the command effect of the electronic whistle.

[0034] Example 3

[0035] This embodiment is basically the same as Embodiment 1 above, except that: the cover 34 and the housing 30 are integrally formed, while the partition plate 31 and the housing 30 are separate structures. When assembling the lamp cap 3 of this structure, since the cover 34 and the housing 30 are integrally formed, the cover 34 forms an installation cavity. First, the buzzer 5 is placed inside the cover, then the partition plate 31 is inserted into the housing 30 and covers the rear end of the cover 34. Finally, glue is injected into the inside of the cover 34 through the glue injection hole 36, thereby fixing the partition plate 31, the cover 34, and the housing 30 together.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
