[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a remotely controlled signal shielding device.

[0026] The utility model provides Figure 1 A remotely controllable signal jammer is shown, comprising a shell 1, a mainboard 2 and an antenna 3. The mainboard 2 is fixedly mounted inside the shell 1, the antenna 3 is fixedly mounted on the top of the shell 1, and a wireless control switch 4 is fixedly mounted on the surface of the mainboard 2. The signal jammer can be manually switched on and off by a remote controller, thereby being used to perform shielding processing on mobile devices.

[0027] In order to achieve the effects of heat dissipation and dust prevention, such as Figure 1-3 As shown, a mounting plate 5 is fixedly provided at the bottom of the shell 1, mounting feet 11 are fixedly provided on both sides of the mounting plate 5, and mounting holes are provided on the mounting feet 11, and bolts can be installed inside the mounting holes so that the mounting plate 5 is fixed to the wall, so that the shell 1 can be wall-mounted; the mounting plate 5 is a hollow structure, and an air inlet pipe 6 is fixedly provided at the center of the lower surface of the mounting plate 5, and an inlet fan 7 is fixedly installed inside the air inlet pipe 6, a heat dissipation air inlet port 8 is provided between the mounting plate 5 and the shell 1, and a plurality of evenly distributed heat dissipation air outlets 9 are provided at the bottom of the shell 1, and dustproof nets 12 are fixedly installed at the pipe mouth of the air inlet pipe 6 and inside the heat dissipation air outlet 9, and the dustproof net 12 can reduce the dust from entering the interior of the shell 1, and a plurality of evenly distributed dustproof air outlets 10 are provided at the edge of the upper surface of the mounting plate 5, and the plurality of dustproof air outlets 10 are all annular and evenly distributed near the surrounding side walls of the shell 1.

[0028] Principle: When the fan inlet 7 is working, it can blow gas into the inside of the mounting plate 5, so that the external air enters into the inside of the shell 1 through the heat dissipation air inlet 8, and then the heat inside the shell 1 is discharged through the heat dissipation air outlet 9, thereby realizing the function of rapid heat dissipation inside the shell 1. At the same time, the gas inside the mounting plate 5 will also be discharged through multiple dust-proof air outlets 10 and blown to the surroundings of the shell 1. At this time, the gas around and on the top of the shell 1 can flow, so that the dust in the air will not fall on the shell 1, thereby playing a better dust-proof role.

[0029] In order to place the housing 1 for use, Figure 1 As shown, support feet 13 are fixedly provided at the four corners of the lower surface of the mounting plate 5, and the length of the support feet 13 is greater than the length of the air inlet pipe 6. The mounting plate 5 is placed on a flat surface for use by the support feet 13, and the air inlet pipe 6 can be lifted to a certain height at the same time, and the lower end of the air inlet pipe 6 will not be blocked.

[0030] Finally, in order to be able to use the signal jammer and the air inlet fan 7 separately, as Figure 1 As shown, the wireless control switch 4 and the switch of the air inlet fan 7 are independently controlled, which can stop the signal jammer from working while the air inlet fan 7 can continue to work.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
