Description

Technical Field

[0001] This utility model relates to the technical field of acoustically transparent screens, and more specifically, to a self-cleaning mechanism for acoustically transparent screens. Background Technology

[0002] A sound-permeable screen is a special type of screen that combines display technology with sound transmission technology. It allows sound to pass through the screen and propagate while maintaining high-definition image display. Although the perforated design of a cinema screen helps sound propagate, it is also prone to accumulating dust, which can affect the viewing experience.

[0003] Based on this, we provide a self-cleaning mechanism for an acoustically transparent screen. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the present invention provides a self-cleaning mechanism for a sound-transparent screen, which can reduce the frequency and cost of manual cleaning, and regular cleaning of the screen can extend its service life and reduce the frequency of replacement.

[0005] The self-cleaning mechanism of the acoustically transparent screen provided by this utility model adopts the following technical solution:

[0006] A self-cleaning mechanism for an acoustically transparent screen includes an acoustically transparent screen; a self-cleaning mechanism disposed on the acoustically transparent screen for cleaning dust from the perforations on the acoustically transparent screen; wherein the self-cleaning mechanism includes a controller disposed on the top of the acoustically transparent screen; a plurality of blowers disposed inside the acoustically transparent screen, and the blowers corresponding to the positions of the perforations; a plurality of dust sensors disposed on the side of the acoustically transparent screen for detecting dust in the perforation area; the dust sensors, blowers, and controller are electrically connected.

[0007] Preferably, the blower includes a rectangular frame disposed inside the acoustically transparent screen, a motor is disposed inside the rectangular frame, and a fan blade is assembled at the output end of the motor.

[0008] Preferably, the fan blade corresponds to a perforation in a specific area.

[0009] Preferably, the controller is equipped with indicator lights on its side.

[0010] Preferably, the self-cleaning mechanism further includes a control panel disposed on the side of the acoustically transparent screen.

[0011] Preferably, a shielding frame is provided inside the acoustically transparent screen at a position relative to the hole, and an electric actuator is mounted on the side of the acoustically transparent screen, with the output end of the electric actuator connected to the shielding frame.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] When the dust sensor detects dust in the sound-transparent screen's aperture, it sends a signal to the controller, which then activates the corresponding motor. This motor drives the fan blades to rotate, drawing air from the back of the sound-transparent screen into and out of the aperture, thus expelling dust and impurities and completing the self-cleaning process. This structural design reduces the frequency and cost of manual cleaning, and regular screen cleaning can extend its lifespan and reduce replacement frequency.

[0014] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0022] Example 1

[0023] This utility model discloses a self-cleaning mechanism for an acoustically transparent screen. (Refer to...) Figures 1 to 4A self-cleaning mechanism for an acoustically transparent screen includes an acoustically transparent screen 1 and a self-cleaning mechanism 2; the self-cleaning mechanism 2 is disposed on the acoustically transparent screen 1 and is used to clean the dust from the holes 3 on the acoustically transparent screen 1.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the self-cleaning mechanism 2 includes a controller 200, several blower components, and several dust sensors 201; the controller 200 is located on the top of the acoustic screen 1; several blower components are located inside the acoustic screen 1, and the blower components correspond to the positions of the holes 3; several dust sensors 201 are located on the side of the acoustic screen 1 and are used to detect dust in the area of ​​the holes 3; the dust sensors 201, the blower components, and the controller 200 are electrically connected.

[0025] like Figure 3 As shown, the blower includes a rectangular frame 202 disposed inside the sound-transparent screen 1, a motor 203 disposed inside the rectangular frame 202, and a fan blade 204 assembled at the output end of the motor 203.

[0026] Specifically, the controller 200 can be a PLC controller, a computer, a CPU, etc. In this embodiment, it is a PLC controller. The PLC controller is electrically connected to each dust sensor 201 and motor 203. When the dust sensor 201 detects dust at the hole 3 of the sound-transparent screen 1, it feeds back the signal to the controller 200, which then starts the corresponding motor 203, causing the motor 203 to drive the fan blade 204 to rotate, allowing air from the back of the sound-transparent screen 1 to enter and exit the hole 3, thereby expelling dust and impurities from the hole 3 and completing self-cleaning. Through this structural design, the frequency and cost of manual cleaning can be reduced, and regular screen cleaning can extend its service life and reduce the frequency of replacement.

[0027] like Figure 3 As shown, the fan blade 204 corresponds to a hole 3 in a certain area.

[0028] like Figure 1 As shown, indicator lights are mounted on the side of the controller 200.

[0029] Specifically, indicator lights are used to display system status, such as cleaning in progress or standby mode.

[0030] like Figure 2 As shown, the self-cleaning mechanism 2 also includes a control panel 205 disposed on the side of the acoustic screen 1.

[0031] Specifically, the control panel 205 is used to manually control the start, stop, and adjustment of the cleaning mode.

[0032] Example 2

[0033] This embodiment is a further optimization based on the above embodiments. The parts that are the same as those in the foregoing technical solutions will not be repeated here. Figure 4 As shown, in order to better realize this utility model, the following arrangement is adopted: In this embodiment, a shielding frame 4 is provided inside the sound-transparent screen 1 at a position relative to the hole 3, and an electric push rod 5 is mounted on the side of the sound-transparent screen 1. The output end of the electric push rod 5 is connected to the shielding frame 4.

[0034] Specifically, when the sound-transparent screen 1 is not in use, the shielding frame 4 can be moved upward by the electric push rod 5, thereby shielding the hole 3. This prevents dust from being stirred up and entering the hole 3 of the sound-transparent screen 1 when external staff are cleaning the cinema.

[0035] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, which will not be described in detail here.

[0036] The self-cleaning mechanism of the acoustically transparent screen according to this embodiment is implemented as follows: When the dust sensor 201 detects dust at the hole 3 of the acoustically transparent screen 1, it feeds back the signal to the controller 200, which then starts the corresponding motor 203, causing the motor 203 to drive the fan blade 204 to rotate, allowing air from the back of the acoustically transparent screen 1 to enter and exit the hole 3, thereby expelling dust and impurities from the hole 3 and completing self-cleaning. Through this structural design, the frequency and cost of manual cleaning can be reduced, and regular screen cleaning can extend its service life and reduce the frequency of replacement.

[0037] When the acoustic screen 1 is not in use, the shielding frame 4 can be moved upward by the electric push rod 5, thereby shielding the hole 3. This prevents dust from being stirred up and entering the hole 3 of the acoustic screen 1 when external staff clean the cinema.
