Description

Technical Field

[0001] The utility model relates to the technical field of infrared receivers, in particular to an anti-interference infrared receiver. Background Art

[0002] An infrared receiver is a device that can receive infrared signals and independently complete the process from infrared reception to output compatible with TTL level signals. Its size is similar to that of an ordinary plastic-encapsulated transistor and it is suitable for various infrared remote controls and infrared data transmission.

[0003] In the existing technology, when an infrared receiver is in a strong light environment, such as strong sunlight outdoors or direct exposure to a strong incandescent lamp indoors, excessive interference light from external sunlight, lamplight, etc. will enter the infrared receiver along with the infrared signal. These interference signals will be superimposed on the original infrared signal, causing signal distortion or weakening, thereby affecting the receiver's decoding ability and accuracy. Therefore, it is necessary to propose a new type of anti-interference infrared receiver. Utility Model Content

[0004] The utility model mainly provides an anti-interference infrared receiver which can conveniently improve the anti-interference effect of the infrared receiver and prevent the signal from being distorted or weakened due to strong light interference.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an anti-interference infrared receiver, comprising a receiver body, a shading component is arranged on the top of the receiver body; the shading component includes a light shield, a rectangular groove is opened on the top of the light shield, a light-transmitting plate is arranged on the inner surface of the rectangular groove, and a baffle is arranged on the front surface of the light shield.

[0006] Compared with the prior art, the advantages and positive effects of the present invention are:

[0007] 1. In the utility model, when used in a strong light environment, a light shield is provided on the top of the receiver body. When the light shield is fixed on the top of the receiver body, the light-collecting part of the receiver can be sealed in conjunction with a baffle to prevent strong light from entering. An infrared-transmissive light-transmitting plate is provided in the rectangular groove on the top, which can effectively reduce the strong light irradiating the light-collecting part and prevent the infrared receiver from being interfered with by strong light, resulting in distortion or weakening of the infrared receiver signal, which affects the decoding ability and accuracy of the receiver and has a good anti-interference effect.

[0008] 2. In the utility model, when used in a low-light environment, the damping slider is symmetrically fixed to the bottom of the light shield, so that when the light shield is pushed by an external force and inserted into the two slide grooves, it can be fixed to the top of the receiver body. In a low-light environment, the bottom plate can be pressed downward to move the two insertion rods downward, which facilitates the quick removal of the baffle, and then the light shield can be pushed in the reverse direction to facilitate the quick removal and use of the light shield, which is highly practical.
