Abstract
Description
Technical Field
[0001] This application relates to the field of electrostatic exciter technology, and more specifically, to an antistatic housing structure for an electrostatic exciter. Background Technology
[0002] An electrostatic exciter, a device that simulates the force of sound waves through electrostatic force, is mainly used to improve sound quality and reduce noise interference.
[0003] Because the existing electrostatic actuators generate heat during operation of their internal electrical components, they operate in a relatively dry environment. This dry environment makes the actuator casing prone to static electricity that is difficult to eliminate, which needs to be improved.
[0004] To address the aforementioned issues, this application provides an anti-static housing structure for an electrostatic exciter. Utility Model Content
[0005] The anti-static housing structure for an electrostatic exciter provided in this application adopts the following technical solution:
[0006] An antistatic housing structure for an electrostatic exciter includes a housing, a mounting plate at the bottom of the housing, a water storage tank at the top of the mounting plate, a rotatable disc at the center of the top of the housing, a connecting frame fixedly mounted on the outer wall of the rotating disc, a scraper fitting the housing installed in the gap between the connecting frame and the housing, a translational groove at the top of the connecting frame, a sliding actuating plate slidably mounted in the translational groove, the actuating plate being connected to the inner wall of the translational groove by a connecting spring, a mounting bracket fixedly mounted on the mounting plate, a water storage tank fixedly mounted on the mounting bracket, a drain outlet on the water storage tank, a baffle plate in the drain outlet, and a linkage plate adapted to the actuating plate on the baffle plate.
[0007] Furthermore, a liquid guide plate is fixedly installed at the bottom of the water storage tank, and the liquid guide plate is located directly below the baffle to guide the water flow to the top of the shell.
[0008] Furthermore, a liquid-absorbing rod for absorbing liquid is movably placed inside the liquid storage tank, and a shielding ring for covering the liquid storage tank is fixedly installed on the outer wall of the liquid-absorbing rod, and the shielding ring is not in contact with the outer wall of the shell.
[0009] Furthermore, a scraper for scraping water from the top of the housing is fixedly installed on the outer wall of the rotating disk.
[0010] Furthermore, the bottom end of the scraper is fixedly connected to the liquid-absorbing rod, and the outer walls of the scraper and the liquid-absorbing rod are both fitted with absorbent cloth sleeves.
[0011] Furthermore, a hidden groove is provided at the center of the top of the housing, and a rotary motor is provided in the hidden groove. The output shaft of the rotary motor is fixedly connected to the rotating disk.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] By wetting the surface of the casing with a wet scraper, static electricity can be avoided due to excessive dryness. The cloth cover on the scraper surface helps to keep the scraper surface moist and accelerates water evaporation, keeping the area around the casing relatively moist and less prone to static electricity.

[0022] Example:
[0023] This application discloses an anti-static housing structure for an electrostatic exciter. Please refer to [link / reference]. Figures 1-3 The system includes a housing 1, a mounting plate 2 at the bottom of the housing 1, a water storage tank 3 at the top of the mounting plate 2, a rotating disk 6 at the center of the top of the housing 1, a connecting frame 7 fixedly mounted on the outer wall of the rotating disk 6, a scraper 8 fitted to the housing 1 installed in the gap between the connecting frame 7 and the housing 1, and the scraper 8 fixedly mounted on the outer wall of the rotating disk 6, a translational slide 10 at the top of the connecting frame 7, a slidable actuating plate 11 slidably mounted in the translational slide 10, the top of the actuating plate 11 being at the same horizontal height as the top of the linkage plate 17, and the actuating plate 11 being connected to the inner wall of the translational slide 10 by a connecting spring 12, a mounting bracket 14 fixedly mounted on the mounting plate 2, a water storage tank 15 fixedly mounted on the mounting bracket 14, water being added to the water storage tank 15 periodically, a drain outlet with a baffle 16 in the drain outlet, a hidden groove on the inner wall of the drain outlet, and the hidden baffle 16 slidably mounted on the drain outlet. The baffle 16 is hidden in the groove, and the baffle 16 is connected to the inner wall of the hidden groove by a return spring. The baffle 16 is provided with a linkage plate 17 that is adapted to the toggle plate 11. Both the linkage plate 17 and the toggle plate 11 are provided with inclined surfaces that can fit together. When the rotating disk 6 rotates, the toggle plate 11 contacts the linkage plate 17 during the rotation. After they fit together, the continuous rotation of the rotating disk 6 will cause the linkage plate 17 and the baffle 16 to be displaced, opening the drain port on the water tank 15. The toggle plate 11 slides in the translation slide 10, and a small amount of water in the water tank 15 will flow out through the drain port. At this time, the scraper 8 and scraper 9, which follow the rotation of the rotating disk 6, scrape the water flowing out and wet the shell 1 to prevent static electricity from being generated on the surface of the shell 1. After the toggle plate 11 continues to move with the rotating disk 6 until the contact between it and the linkage plate 17 is broken, the connecting spring 12 and the return spring can push the toggle plate 11 and the baffle 16 to return to their original positions.
[0024] A liquid guide plate 13 is fixedly installed at the bottom of the water tank 15. The liquid guide plate 13 is located directly below the baffle 16 to guide the water flow to the top of the shell 1. A waterproof groove is provided at the bottom of the water tank 15 to prevent the water that leaks a small amount from the drain outlet from covering the bottom plate of the water tank 15 and to provide an anti-static effect for the shell 1.
[0025] A liquid-absorbing rod 5 is movably placed inside the liquid storage tank 3, and a shielding ring 4 is fixedly installed on the outer wall of the liquid-absorbing rod 5 to cover the liquid storage tank 3. The shielding ring 4 is not attached to the outer wall of the shell 1, and excessive water will flow into the liquid storage tank 3 along the surface of the shell 1.
[0026] A scraper 9 for scraping water from the top of the housing 1 is fixedly installed on the outer wall of the rotating disk 6. The scraper 9 can evenly scrape the water from the top of the housing 1.
[0027] The bottom end of the scraper 8 is fixedly connected to the liquid suction rod 5, and the outer walls of the scraper 8 and the liquid suction rod 5 are both fitted with a cloth cover that can absorb water, so that the surface of the scraper 8 is kept moist and the water evaporates faster, so that the periphery of the shell 1 is kept relatively moist and static electricity is avoided.
[0028] A hidden groove is provided at the center of the top of the housing 1, and a rotary motor is installed in the hidden groove. The output shaft of the rotary motor is fixedly connected to the rotating disk 6. The rotary motor is driven by an external power source to make the rotating disk 6 rotate clockwise.
[0029] The implementation principle of this embodiment is as follows: During use, the rotary motor drives the rotating disk 6 to rotate, causing the actuating plate 11 to contact the linkage plate 17 during rotation. After the two are in contact with each other, the continuous rotation of the rotating disk 6 will cause the linkage plate 17 and the baffle plate 16 to be displaced, opening the drain port on the water storage tank 15. The actuating plate 11 slides in the translational slide groove 10, and a small amount of water in the water storage tank 15 will flow out through the drain port. At this time, the scraper 8 and scraper 9, which follow the rotation of the rotating disk 6, scrape the outflowing water and wet the housing 1 to prevent static electricity from being generated on the surface of the housing 1. After the actuating plate 11 continues to move with the rotating disk 6 until the contact between it and the linkage plate 17 is broken, the connecting spring 12 and the return spring can push the actuating plate 11 and the baffle plate 16 to return to their original positions and close the drain port.
[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
