Example one

Referring to fig. 1, the movable heating tube electric heater of the present embodiment includes a heating tube 1, a reflector 2, and a moving mechanism.

In this embodiment, the heating tube 1 is a carbon tube. Of course, in other embodiments, the radiation-type heat-generating tube may be a quartz tube, a halogen tube, a black tube, or the like.

The reflecting cover 2 is arranged facing the heating tube 1 and is parallel to the heating tube 1, and the section of the reflecting cover 2 is approximately a parabolic curved surface. The heating tube 1 is connected to the moving mechanism, the heating tube 1 is located at a focus of the reflector 2 by default, and the heating tube 1 can be driven by the moving mechanism to move to a position in front of the focus, which is relatively closer to the reflector 2, or a position in back, which is relatively farther from the reflector 2.

It is understood that the number of the moving mechanisms may be one or more. When the number of the moving mechanisms is plural, the plural moving mechanisms are respectively connected to different height positions of the heating tube 1. For example, in the present embodiment, in order to ensure that the carbon tube can move up and down synchronously, the number of the moving mechanisms is two, and the two moving mechanisms are respectively connected with two ends of the heating tube 1.

Specifically, the moving mechanism includes a rotation control mechanism 3 and a rotation-translation converting mechanism 4. The rotation control mechanism 3 is used to realize a rotational movement. The rotation and translation conversion mechanism 4 is respectively connected with the rotation control mechanism 3 and the heating tube 1, and is used for converting the rotation motion of the rotation control mechanism 3 into translation motion so as to drive the heating tube 1 to translate.

Wherein the rotation-translation converting mechanism 4 includes: a rack 41 which is connected with the heating tube 1 and is vertical to the heating tube 1, a fixed bracket 42 and a guide rail 43 which supports the fixed bracket 42. The fixing bracket 42 is connected to the rack 41 and the heating tube 1, and in this embodiment, the fixing bracket 42 and the rack 41 are integrally formed. The guide rail 43 is slidably engaged with the fixed bracket 42, in this embodiment, the guide rail 43 includes a pair of sliding grooves, two sides of the fixed bracket 42 are respectively embedded in the pair of sliding grooves and slidably engaged with the pair of sliding grooves, that is, the fixed bracket 42 and the guide rail 43 are slidably engaged in a manner similar to a drawer type.

Wherein, the rotation control mechanism 3 comprises a rotating device 31, a connecting rod 32 and a gear 33. The rotating means 31 is embodied as a knob. The connecting rod 32 is fixed with the whole machine, the connecting rod 32 is parallel to the heating tube 1, the connecting rod 32 and the heating tube 1 are both positioned on the middle split surface of the over-focus point of the reflector 2, and the connecting rod 32 is coaxially connected with the rotating device 31 and is used for rotating under the driving of the rotating device 31. The gear 33 is sleeved on the connecting rod 32 and meshed with the rack 41, and the gear 33 can rotate along with the connecting rod 32.

The two moving mechanisms of the present embodiment share the same connecting rod 32 and the same rotating device 31. When other larger number of moving mechanisms are provided, there is also a common connecting rod 32 and rotating means 31. In summary, when the moving mechanism is plural, it is only necessary to add the corresponding number of gears 33 and the rotation-translation converting mechanism 4.

The working principle of the embodiment is as follows: referring to fig. 2, the left diagram in fig. 2 shows the heating tube 1 at the focal position, and the corresponding heat reflection situation is shown in the middle diagram in fig. 3. When the heating tube 1 is desired to move backwards, only the knob needs to be rotated, at this time, the gear 33 on the connecting rod 32 also rotates, and the gear 33 is meshed with the rack 41, so that the rack 41 moves backwards linearly along with the rotation of the gear 33, the fixed bracket 42 moves backwards along the guide rail 43, the heating tube 1 locked on the fixed bracket 42 also moves backwards, as shown in the right diagram of fig. 2, the heating tube 1 moves to the back of the focus, and at this time, the heat reflection situation is as shown in the left diagram of fig. 3. Similarly, when the heating tube 1 is desired to move forward, only the knob needs to be rotated in the opposite direction, and the corresponding heat reflection situation is shown in the right diagram of fig. 3.

The effect of this embodiment is: the heating tube 1 can freely move relative to the whole machine, when the heating tube moves to different positions, different heat can be obtained to be dispersed on the premise of not changing power, for example, as shown in fig. 4, when the focal position of the reflector 2 moves towards the front of the machine body, the heat can be focused on the front, when the focal position moves towards the rear of the machine body, the heat can be relatively uniformly dispersed, and a user can select the position of the heating tube according to requirements. Has the advantages of convenient operation, high heating efficiency, economy, energy conservation and the like.

Example two

Referring to fig. 4, the present embodiment is different from the first embodiment in that the rotating device 31 is a motor, and is not a knob. Thus, the electric control of the moving heating tube 1 can be realized.
