Abstract

The present invention relates to the technical field of infrared lamp tubes, and specifically to an infrared lamp tube with an adjustable heating area. A second screw rod embedded in the lamp tube is rotatably connected inside the first through hole and the second screw hole, and the right end of the second screw rod passes through the lamp base and is connected to a second connecting block. The lower ends of the left slider and the right slider are both screwed with a ring surrounding the heating wire, and a heat insulation sleeve is adhesively bonded between the rings through a high-temperature resistant glue. By rotating the first connecting block and the second connecting block, the first screw rod and the second screw rod can be rotated. When the first screw rod and the second screw rod rotate, the left slider and the right slider can slide left and right, thereby pulling the heat insulation sleeve to stack and contract or expand. Since the heat insulation sleeve is made of fiberglass cloth, the range of the heat insulation sleeve blocking the heating wire can be adjusted as the heat insulation sleeve contracts or expands, so that the heating area can be adjusted, solving the problem that the heating area of the current infrared lamp tube is fixed.

[0002] An infrared lamp tube, also called an infrared heating tube lamp tube, is composed of a tungsten wire inserted into an air-filled quartz tube. The tungsten wire heats up under the action of an alternating voltage and heats the gas in the quartz tube, thereby generating infrared radiation. Quartz near-infrared and far-infrared lamps use transparent or semi-transparent quartz glass as the lamp tube shell to produce near-infrared or far-infrared radiation spectra.

[0003] According to a partitioned heating infrared lamp tube with the Chinese patent number "CN201820202152.3", it includes a lamp tube and a lamp holder. The lamp tube is installed on the lamp holder. A heating wire is arranged inside the lamp tube. When heating in partitions, the heating area is fixed, which easily causes uneven heating when heating objects of different sizes. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings and other embodiments can be obtained.

[0020] In the first embodiment, as Figures 1-3 shown, the present embodiment discloses an infrared lamp tube with an adjustable heating area. The infrared lamp tube includes: a lamp tube 100 and a lamp base 200. There are two lamp bases 200 in total, and the two lamp bases 200 are respectively installed at the left and right ends of the lamp tube 100. A heating wire 101 is arranged in the middle of the lamp tube 100. First, the heating wire 101 is powered on. Since the heating wire 101 is a nickel-chromium heating wire and the heating wire 101 is in a spiral structure, the heating wire 101 is heated by being powered on to perform a heating operation.

[0021] In the second embodiment, as Figures 1-3As shown in the figure, on the basis of the first embodiment, a top block 102 is adhesively connected to the top end of the inner wall of the lamp tube 100 by means of a high-temperature resistant glue. A chute 103 is formed at the lower end of the top block 102. The left and right sides of the inside of the chute 103 are respectively clamped and slidably connected with a left slider 104 and a right slider 109. The upper and lower sides of the inside of the left slider 104 are respectively provided with a first screw hole 105 and a first through hole 106. The upper and lower sides of the inside of the right slider 109 are respectively provided with a second through hole 110 and a second screw hole 111. A first screw rod 300 embedded in the lamp tube 100 is rotatably connected inside the first screw hole 105 and the second through hole 110. The left end of the first screw rod 300 passes through the lamp socket 200 and is connected to a first connecting block 301. A second screw rod 400 embedded in the lamp tube 100 is rotatably connected inside the first through hole 106 and the second screw hole 111. The right end of the second screw rod 400 passes through the lamp socket 200 and is connected to a second connecting block 401. When it is necessary to adjust the heating range of the heating wire 101, by rotating the first connecting block 301 and the second connecting block 401 at one end of the lamp socket 200, the first screw rod 300 and the second screw rod 400 can be rotated. When the first screw rod 300 and the second screw rod 400 rotate, since the left slider 104 moves left and right as the first screw rod 300 rotates, and the right slider 109 moves left and right as the second screw rod 400 rotates, so as the first screw rod 300 and the second screw rod 400 rotate inside the first screw hole 105 and the second screw hole 111 respectively, and the left slider 104 and the right slider 109 are both clamped in the chute 103 in the top block 102, the left slider 104 and the right slider 109 can only move left and right. Thus, like turning a screw, the left slider 104 and the right slider 109 move left and right in the chute 103. Since the diameters of the second through hole 110 and the first through hole 106 are equal, the diameter of the second through hole 110 is 5 mm - 10 mm, the diameter of the second screw rod 400 is equal to the diameter of the first screw rod 300, the diameter of the second screw rod 400 is 3 mm - 8 mm, and the diameter of the second screw rod 400 is shorter than the diameter of the second through hole 110, when the left slider 104 and the right slider 109 move left and right, the second screw rod 400 can pass through the left slider 104 and the first screw rod 300 can pass through the right slider 109 through the first through hole 106 and the second through hole 110 respectively.

[0022] In the third embodiment, as Figures 1-3As shown, on the basis of the first or second embodiment, a ring 107 surrounding the heating wire 101 is screwed to the lower ends of the left slider 104 and the right slider 109, and a heat insulation sleeve 108 is adhesively bonded between the rings 107 with a high-temperature resistant glue. When the left slider 104 and the right slider 109 move, they will drive the ring 107 to move, thereby pulling the heat insulation sleeve 108 to stack and contract or expand. Since the heat insulation sleeve 108 is made of fiberglass cloth, the range of the heat insulation sleeve 108 covering the heating wire can be adjusted as the heat insulation sleeve 108 contracts or expands, so that the heating area can be adjusted.

[0023] In the above embodiments, the following are used: 100 - lamp tube; 101 - heating wire; 102 - top block; 103 - chute; 104 - left slider; 105 - first screw hole; 106 - first through hole; 107 - ring; 108 - heat insulation sleeve; 109 - right slider; 110 - second through hole; 111 - second screw hole; 200 - lamp holder; 300 - first screw rod; 301 - first connecting block; 400 - second screw rod; 401 - second connecting block can all be obtained through market purchase or private customization.

[0024] It should be noted that the above embodiments can be freely combined according to needs. The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
