Description

Technical Field

[0001] The utility model relates to the technical field of infrared ray lamps, in particular to a PVC infrared ray lamp cover. Background Art

[0002] Infrared ray lamps, also known as infrared lamps, can generate infrared electromagnetic waves, generate high temperatures and radiate outward. Infrared lamps are widely used in industry, agriculture, medical care, and home.

[0003] But at the same time, because infrared lamps generate high temperatures, the lampshades used to protect them need to have certain special requirements. In addition, the wavelength of infrared light emitted by infrared lamps coincides with the antennae-sensitive wavelength of some flying insects, making them easily attracted to infrared lamps and thus colliding with them, causing pollution.

[0004] PVC, or polyvinyl chloride, is a widely used plastic material with good physical properties, such as hardness, tensile strength, chemical resistance, etc., and is relatively cheap, making it very suitable as a lampshade for ordinary lighting lamps. However, it has a low melting point and poor thermal conductivity, and cannot be used well as a lampshade for infrared lamps. If the lampshade made of PVC can be cooled and the high temperature generated by the infrared lamp can be isolated, then the lampshade made of PVC can be used as a lampshade for infrared lamps.

[0005] In order to solve the technical problem, the utility model proposes a PVC infrared ray lampshade. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1-5 As shown, a PVC infrared lampshade includes a lampshade shell 1, which is made of PVC plastic. Connecting plates 2 are connected to both sides of the lampshade shell 1. A connector 11 is connected to the upper end of the connecting plate 2. The connector 11 is connected to an external power supply. An infrared lamp rod 3 is connected to the side end of the connecting plate 2. A wire is arranged inside the connecting plate 2. The wire is connected to the tungsten filament rod inside the infrared lamp rod 3, so that the infrared lamp rod 3 can be powered by the connecting plate 2 to generate infrared rays and heat.

[0028] An infrared reflection layer 4 is arranged on the inner wall of the lampshade shell 1. The infrared reflection layer 4 is made of an aluminum film. The reflectivity of the aluminum film can reach more than 90% in the infrared band. At the same time, the cost is low. The infrared ray lamp rod 3 can effectively reflect the rays irradiated to the inner wall of the lampshade shell 1. The cross-section of the lampshade shell 1 is U-shaped. The infrared ray lamp rod 3 is located in the lampshade shell 1 and does not contact the infrared reflection layer 4 on its inner wall, so that the infrared rays can have reflection space.

[0029] An insulating layer 5 is provided at the outer end of the infrared reflecting layer 4, and a ventilation hole 6 is opened in the lampshade shell 1, and the ventilation hole 6 is located at the outer end of the insulating layer 5. A heat dissipation fan 7 is provided at one side end of the lampshade shell 1, and an exhaust hood 8 is provided at the other side end. Two connecting plates 2 are respectively located between the heat dissipation fan 7 and the lampshade shell 1, and between the exhaust hood 8 and the lampshade shell 1. The heat dissipation fan 7 is connected with the lampshade shell 1 and the ventilation hole 6. Starting the heat dissipation fan 7 will blow air into the lampshade shell 1 and the ventilation hole 6, so that the heat in the lampshade shell 1 can be quickly discharged. The wind passes through the ventilation hole 6 to cool the lampshade shell 1.

[0030] Dust-proof nets are provided at the air inlet at the side end of the heat dissipation fan 7 and in the exhaust cover 8, and the dust-proof nets are used to prevent dust from entering the lamp cover shell 1 and contaminating the infrared ray lamp rod 3. A transparent glass plate 9 is connected to the lower end of the lamp cover shell 1. The material of the transparent glass plate 9 is the same as the glass shell material of the infrared ray lamp rod 3, so as not to hinder the radiation of infrared rays and to protect the infrared ray lamp rod 3 from being contaminated by dust and flying insects.

[0031] The lower ends of both sides of the lampshade shell 1 are connected with illuminating lamps 10, which are connected to the connecting plate 2. The illuminating lamps 10 are located inside the lampshade shell 1. The light range irradiated by the illuminating lamps 10 is the same as the range irradiated by the infrared ray lamp stick 3. Since infrared rays are invisible to the human eye, the range of light irradiated by the illuminating lamps 10 can be used to determine the irradiation range of the infrared ray lamp stick 3 in disguise. The light of the infrared ray lamp stick 3 cannot irradiate the illuminating lamps 10, so the high temperature generated by the infrared ray lamp stick 3 will be difficult to be transmitted to the illuminating lamp 10.

[0032] A fixed plate 12 is connected to the lower end of the connecting plate 2, a track rod 13 is connected between the two fixed plates 12, and a threaded rod 14 is rotatably connected. A motor 15 is connected to the side end of the fixed plate 12, and a driving end of the motor 15 is connected to the threaded rod 14. The outer end of the threaded rod 14 is threadedly connected to a movable plate 16, and the track rod 13 is slidably connected in the movable plate 16. The track rod 13 is used to constrain the movable plate 16 so that it can only move along the track rod 13 but cannot rotate. For this reason, starting the motor 15 will be able to drive the threaded rod 14 to rotate, and the rotation of the threaded rod 14 will act on the movable plate 16. Under the action of the threaded rod 14 and the track rod 13, the movable plate 16 will move at the lower end of the transparent glass plate 9. A brush strip 17 is connected to the upper end of the movable plate 16, and the brush strip 17 contacts the lower surface of the transparent glass plate 9. Driven by the movable plate 16, the brush strip 17 will clean the lower surface of the transparent glass plate 9. A control box 18 is connected to the side end of the fixed plate 12, and the control box 18 is used to control the operation of the device.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
