DETAILED DESCRIPTION
[0025] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.
[0027] like Figure 1-6 As shown, the utility model provides a novel sound insulation and shielding device, including a base component 10, a storage shielding component 20 and a vacuum control component 30. During the meeting, the mobile phones of the participants can be placed in the sound insulation and shielding device. The storage shielding component 20 makes use of electromagnetic shielding materials, which can effectively block the interference and intrusion of external wireless signals, thereby preventing the wireless communication functions of mobile phones and other devices from being used or interfered with by external devices. At the same time, the device is also equipped with a vacuum control component 30. Through the vacuum operation, the vacuum degree inside the shielding box can be maintained. In a vacuum environment, the propagation of sound is greatly restricted, thereby enhancing the sound insulation effect. Combined with the sound insulation layer 214 specially arranged inside the shielding box, the device can isolate the sound to the maximum extent, ensure the confidentiality of the meeting content and prevent it from being stolen by the recording equipment, and also effectively avoid the sound of the mobile phone alarm and other sounds from being transmitted from the inside, interfering with the normal progress of the meeting, thereby improving the confidentiality of the meeting and optimizing the meeting environment, so that the participants can focus more on the content of the meeting.
[0028] like Figure 1-2 As shown, the base assembly 10 includes a base shell 11 , a support foot 12 is disposed at the bottom of the base shell 11 , and an air inlet 13 is disposed at the rear side of the base shell 11 .
[0029] In this embodiment, the storage shielding assembly 20 includes a shielding box 21, which is composed of a shielding box base 211 and a shielding box cover 212 that are hinged to each other. The shielding box base 211 is arranged on the top of the base shell 11, and electric support rods 216 are arranged on the left and right sides of the shielding box base 211. The output shaft of the electric support rod 216 is hinged to the left and right sides of the shielding box cover 212, and the support column on the supporting foot 12 is in conflict with the bottom of the shielding box base 211. A mobile phone storage rack 23 is arranged inside the shielding box 21, and a plurality of mobile phone storage slots 231 are opened on the top of the mobile phone storage rack 23, and a pressure switch 232 is arranged on the bottom wall of the mobile phone storage slot 231.
[0030] Embodiment 1, as Figure 5 As shown, when a mobile phone is placed in the mobile phone storage slot 231, the pressure switch 232 senses it and transmits information to the controller 34, and the controller 34 displays it on the display screen 36. Through the display screen 36, the participants can see whether there is any empty space in the sound insulation and shielding device, thereby improving the user experience.
[0031] like Figure 4 As shown, a sealing ring 215 is provided on the top of the shielding box base 211, and the electric support rod 216 is retracted, and the shielding box cover 212 contacts the sealing ring 215 to form a seal. Since the utility model needs to use the vacuum principle to minimize the propagation of sound inside and outside the shielding box 21, the sealing ring 215 needs to be used to ensure the tightness of the inside of the shielding box 21 before vacuuming.
[0032] In this embodiment, the shielding box base 211 includes an electromagnetic shielding layer 213, and the inner wall surface of the electromagnetic shielding layer 213 is provided with a sound insulation layer 214. The shielding box cover 212 is provided with the same electromagnetic shielding layer 213 and the sound insulation layer 214, wherein the material of the electromagnetic shielding layer 213 is mainly iron, copper or aluminum, which have high reflectivity and absorption of electromagnetic waves, thereby playing a role in shielding wireless signals. The sound insulation layer 214 mainly uses sound insulation cotton or sound insulation felt. The cost of sound insulation cotton is relatively low, but the sound insulation effect is relatively poor. The sound insulation felt not only has a better sound insulation effect, but can also suppress the vibration of objects, reduce solid sound transmission, and has a better sound insulation and shielding effect on mobile phone vibration, but the cost is relatively high.
[0033] like Figure 2 As shown, the front side of the bottom of the mobile phone storage rack 23 is arranged on the bottom wall of the shielding box base 211, and the rear side of the bottom of the mobile phone storage rack 23 is arranged on the top of the L-shaped honeycomb partition 22, so that the mobile phone storage rack 23 is inclined toward the front side, and the mobile phone storage slot 231 is also designed to be stepped. When the mobile phone is placed inside, the mobile phone on the front side can be prevented from blocking the mobile phone on the rear side. After the meeting, it is convenient for participants to quickly find their mobile phones.
[0034] In embodiment 2, a side groove is provided on the rear side wall of the mobile phone storage slot 231, and a wireless charging device is provided inside the side groove. When the mobile phone is placed inside the mobile phone storage slot 231, it can be wirelessly charged. Since such confidential meetings usually last for a long time, the mobile phones of the participants are in a state of continuous power loss when the power is running out. After the meeting, they cannot contact the outside world in time, causing unnecessary trouble. This problem can be effectively solved by adding wireless charging.
[0035] like Figure 1-3 As shown, the vacuum control component 30 includes a vacuum air pump 31 and a pressure gauge 32 arranged on the rear side of the bottom of the shielding box 21, an L-shaped honeycomb partition 22 is arranged on the rear side of the bottom of the shielding box 21, a one-way solenoid valve 33 is arranged on the inner side of the L-shaped honeycomb partition 22, a controller 34 is arranged at the bottom of the base shell 11, and a button 35 and a display screen 36 are arranged on the front side of the base shell 11.
[0036] It should be noted that the gas flow direction of the one-way electromagnetic valve 33 flows from the inside to the outside of the shielding box 21 , and the gas flow direction of the vacuum air pump 31 flows from the outside to the inside of the shielding box 21 .
[0037] Furthermore, a dust filter plate 14 is provided on the rear side wall of the base shell 11 near the air inlet 13. The dust filter plate 14 prevents external dust from entering the shielding box 21 and affecting the air tightness of the shielding box 21. It also prevents the accumulation of dust, which may cause a certain degree of pollution to the mobile phones of the participants and bring them a bad experience.
[0038] like Figure 6 As shown, the signal output ends of the pressure switch 232 and the pressure gauge 32 are communicatively connected with the signal input ends of the controller 34, the signal input ends of the vacuum air pump 31, the one-way solenoid valve 33, the electric support rod 216 and the display screen 36 are communicatively connected with the signal output ends of the controller 34, and the button 35 is electrically connected to the controller 34.
[0039] Embodiment 3, the mobile phone is placed in the mobile phone storage slot 231, and the button 35 is pressed, which sends a signal to the controller 34, thereby controlling the electric support rod 216 to retract to the shortest. At this time, the shielding box is completely sealed, and then the vacuum air pump 31 is controlled to open to evacuate the inside of the shielding box. When the pressure gauge 32 reaches the threshold, it sends a signal to the controller 34, and the controller 34 then controls the vacuum air pump 31 to close, that is, the vacuuming is completed. The principle of blocking sound propagation in a vacuum environment and the sound insulation layer 214 are used to isolate the sound from propagation inside and outside the shielding box to the maximum extent. When the mobile phone needs to be taken out, another button 35 is pressed. After receiving the instruction, the controller 34 controls the one-way solenoid valve 33 to open, and the shielding box 21 is depressurized. The pressure gauge 32 is used for detection. When it is detected that the internal and external air pressures are equal, a signal is sent to the controller 34, thereby closing the one-way solenoid valve 33, and controlling the electric support rod 216 to extend, and the shielding box cover 212 can be opened to take out the mobile phone.
[0040] The above structure solves the problem in the prior art that a specially configured mobile phone can be used to secretly record and eavesdrop on the content of a meeting without being detected, resulting in the risk of core information being leaked, thereby causing huge damage to the interests of companies and individuals.
[0041] It should be noted that the specific models and specifications of the electric support rod 216, pressure switch 232, vacuum air pump 31, pressure gauge 32, one-way solenoid valve 33, controller 34 and display screen 36 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.
[0042] The power supply and principles of the electric support rod 216, the pressure switch 232, the vacuum air pump 31, the pressure gauge 32, the one-way solenoid valve 33, the controller 34 and the display screen 36 are clear to those skilled in the art and will not be described in detail here.
[0043] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
