Description

Technical Field

[0001] This utility model relates to the field of audio electronic product technology, specifically an insect-proof ceiling speaker. Background Technology

[0002] A ceiling loudspeaker is an electroacoustic conversion device installed on the surface of a ceiling. It converts electrical signals into sound waves and radiates them into the space through a vibrating diaphragm. Due to its open structure and exposure to the environment, insects such as mosquitoes and cockroaches can easily enter the loudspeaker through the sound outlet or air inlet, causing diaphragm damage, short circuits, or blockage of acoustic pathways, thereby reducing sound clarity or even causing equipment failure. Insect problems are more pronounced in humid or food-rich areas, seriously affecting the lifespan and functional stability of the ceiling loudspeaker.

[0003] Existing technologies typically employ two methods to prevent insect infestation: one is to seal the gaps in the casing or add waterproof gaskets to block insect pathways; the other is to choose a concealed installation structure to embed the speaker inside the ceiling to reduce the risk of exposure. However, the above solutions have significant limitations: the sealed design cannot completely cover the speaker's sound outlet area, and the gaskets are prone to aging and failure after long-term use; although the concealed installation method can reduce the probability of insect infestation, the construction cost is high and maintenance is inconvenient, and no specific protective measures are taken for the sound outlet, which means that insects may still enter the speaker cavity through the acoustic opening, ultimately shortening the equipment's lifespan and affecting the audio output effect.

[0004] An investigation revealed that a Chinese utility model patent (publication number: CN208905207U) discloses an insect-proof ceiling speaker, comprising a base on which a speaker body, a speaker transformer, and a fixing clip are mounted. The speaker body and the speaker transformer are electrically connected. The base also has a perforated window with multiple insect-proof ribs. This utility model incorporates an insect-proof structure on the base and improves the mounting structure of the fixing clip, making installation convenient and effectively preventing insects, rats, and other animals from damaging the speaker from inside the ceiling.

[0005] Existing technologies use insect-proof structures and improved mounting structures for fixing clips to prevent insects or rats from damaging the speaker from inside the ceiling. However, no measures are taken to prevent insects from entering the sound outlet. This results in insects damaging the diaphragm after entering the sound outlet, and insect carcasses clogging the speaker mesh, causing poor sound output.

[0006] Therefore, this utility model provides an insect-proof ceiling speaker to solve the above problems. Utility Model Content

[0007] This invention provides an insect-proof ceiling speaker, which aims to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an insect-proof ceiling speaker, comprising a sound-emitting unit, a housing assembly fixedly connected to the sound-emitting unit; a cleaning assembly fixedly connected to the housing assembly; and an insect-repelling assembly fixedly connected to the housing assembly. The housing assembly includes a cylindrical shell fixedly connected to the sound-generating unit, a flange shell fixedly connected to the cylindrical shell, a liquid outlet hole on the cylindrical shell, a fixing hole on the cylindrical shell, a fixing buckle rotatably connected to the cylindrical shell, a liquid replenishment hole on the cylindrical shell, and a mounting groove on the flange shell.

[0009] As a preferred technical solution of this application, the cleaning component includes a servo motor fixedly connected to the mounting slot, a brush handle fixedly connected to the servo motor, and brush bristles fixedly connected to the brush handle.

[0010] As a preferred technical solution of this application, the insect repellent component includes a liquid outlet tube fixedly connected to the liquid outlet hole, a liquid bladder fixedly connected to one end of the liquid outlet tube, a replenishment tube fixedly connected to the liquid bladder, a replenishment head fixedly connected to the replenishment tube, and an immersion plate fixedly connected to the other end of the liquid outlet tube.

[0011] As a preferred technical solution of this application, the insect repellent component includes a sound outlet hole opened on the impregnation sheet, an impregnation hole opened on the impregnation sheet, an insect-proof net fixedly connected to the sound-generating unit, a porous protrusion fixedly connected to the insect-proof net, and a sound-emitting hole opened on the insect-proof net.

[0012] As a preferred technical solution of this application, the sound outlet hole and the sound emission hole are equal in size, number, and position, the outer diameter of the porous protrusion is equal to the inner diameter of the immersion hole, and the immersion sheet and the porous protrusion are made of the same material.

[0013] As a preferred technical solution of this application, the movement range of the brush bristles completely covers the impregnation sheet, and the movement of the brush bristles will not cause structural damage to the porous protrusions and the impregnation sheet.

[0014] This invention stores insect repellent in a liquid sac. The drug is slowly released through a liquid outlet tube, an impregnation plate, and porous protrusions. The drug is then covered by the insect-proof net by the capillary action of the impregnation plate and porous protrusions, causing insects to stay away when they approach the sound-emitting unit. At the same time, the cleaning component cleans the insect corpses and dust on the impregnation plate and insect-proof net, keeping the sound outlet and sound emission hole clean and unobstructed.

Detailed Implementation

[0017] 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.

[0018] This utility model provides an insect-proof ceiling speaker, such as Figure 1-8 As shown, it includes a sound-generating unit 1, a housing assembly 2 fixedly connected to the sound-generating unit 1; a cleaning assembly 3 fixedly connected to the housing assembly 2; and an insect-repelling assembly 4 fixedly connected to the housing assembly 2. The housing assembly 2 includes a cylindrical shell 21 fixedly connected to the sound-generating unit 1, a flange shell 22 fixedly connected to the cylindrical shell 21, a liquid outlet 23 opened on the cylindrical shell 21, a fixing hole 24 opened on the cylindrical shell 21, a fixing buckle 25 rotatably connected to the cylindrical shell 21, a liquid replenishment hole 26 opened on the cylindrical shell 21, and a mounting groove 27 opened on the flange shell 22.

[0019] The cleaning assembly 3 includes a servo motor 31 fixedly connected to the mounting slot 27, a brush handle 32 fixedly connected to the servo motor 31, and brush bristles 33 fixedly connected to the brush handle 32.

[0020] The insect repellent assembly 4 includes an outlet pipe 41 fixedly connected to the outlet hole 23, a liquid bladder 42 fixedly connected to one end of the outlet pipe 41, a replenishment pipe 43 fixedly connected to the liquid bladder 42, a replenishment head 44 fixedly connected to the replenishment pipe 43, and an immersion plate 45 fixedly connected to the other end of the outlet pipe 41.

[0021] The insect repellent component 4 includes a sound outlet 46 formed on the impregnation plate 45, an impregnation hole 47 formed on the impregnation plate 45, an insect-proof net 48 fixedly connected to the sound-generating unit 1, a porous protrusion 49 fixedly connected to the insect-proof net 48, and a sound emission hole 410 formed on the insect-proof net 48.

[0022] The sound outlet 46 and the sound emission hole 410 are equal in size, number, and position. The outer diameter of the porous protrusion 49 is equal to the inner diameter of the wetting hole 47. The wetting sheet 45 and the porous protrusion 49 are made of the same material.

[0023] The movement range of the bristles 33 completely covers the impregnation sheet 45, and the movement of the bristles 33 will not cause structural damage to the porous protrusions 49 and the impregnation sheet 45.

[0024] Specifically, compared to traditional ceiling speakers that focus more on insect and rodent prevention inside the ceiling, they often lack protection for the speaker's sound output location. In this device, the sound-generating unit 1 is located inside the housing assembly 2 and is sealed by a liquid bladder 42. Simultaneously, the liquid bladder 42 introduces the drug into the impregnation plate 45 through the outlet pipe 41. Both the impregnation plate 45 and the porous protrusions 49 are made of porous material, which allows the drug solution in the liquid bladder 42 to quickly diffuse under capillary action, causing the drug solution to adhere to the insect-proof net 48. When insects approach, the drug solution... The odor will not approach, reducing the risk of insects entering the sound-generating unit 1. At the same time, the sound outlet 46 and the sound emission outlet 410 are equal in size, number, and position, so that the sound emission and diffusion will not be affected. When it is necessary to replenish the liquid sac 42, the replenishment head 44 is connected through a special tool, and the replenishment is carried out through the replenishment tube 43. When the saturation plate 45, the porous protrusion 49, or the insect-proof net 48 is covered with the corpses of insects, the servo motor 31 drives the brush handle 32, and then drives the bristles 33 to clean the saturation plate 45, the porous protrusion 49, or the insect-proof net 48.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
