Description

Technical Field

[0001] The invention relates to the field of radiant heaters, and in particular to a radiant heater. Background Art

[0002] At present, the existing heater refers to the equipment used for heating. There are many kinds of heaters. The most common electric heater is a heating equipment that uses electricity as energy for heating. It can also be called electric heating. In recent years, it has gradually become popular to use electricity to heat water for heating. It can be widely used in various civil and public buildings such as residential, office, hotel, shopping mall, hospital, school, train carriages, mobile heating, simple activity houses, etc.

[0003] Currently, radiant heaters use a rod-shaped radiant heating rod, and users manually rotate the radiant heating rod to adjust the radiation angle. During the rotation, the user may hit the surface of the radiant heating rod, which poses a high risk of severe burns. Summary of the invention

[0004] In view of the above problems, the present invention proposes a radiant heater, which solves the defect of the existing radiant heater that during the rotation process, it hits the surface of the radiant heating rod, which has a high risk of serious burns.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A radiant heater comprises: a body, wherein a long strip-shaped mounting groove is provided on the body, a rotatable radiant heating rod is installed in the mounting groove, an electric heating structure is arranged inside the radiant heating rod, a safety automatic control component is installed on the side wall of the mounting groove, the safety automatic control component is externally connected to a control unit, and the safety automatic control component is used to automatically shut down the electric heating structure for a period of time when the radiant heating rod is manually rotated.

[0007] The present invention provides a safety automatic control component, which is used to automatically shut down the electric heating structure for a period of time when the radiant heating rod is manually rotated, thereby reducing the risk of serious burns. In this way, the radiant heating rod is stopped from working, which improves the safety of use.

[0008] Optionally, the safety automatic control component includes an iron part installed in the radiant heating rod.

[0009] Optionally, an arc-shaped transparent slide cylinder is provided in the side wall of the installation groove, a magnetic movable ball is provided in the slide cylinder, the movable ball is connected to one end of the slide cylinder through an elastic rope, and the iron part is used to drive the movable ball to move.

[0010] Optionally, an activity hole is provided in the activity ball, the activity hole runs through left and right sides of the activity hole, and the outer side wall of the activity hole is made of a transparent material.

[0011] Optionally, a conductive piston is provided in the slide cylinder, and a certain amount of hot melt adhesive is filled in the slide cylinder near the movable ball. The hot melt adhesive is transparent after melting and white after solidifying; and compressed gas is filled in the slide cylinder away from the movable ball.

[0012] Optionally, a conductive hemisphere is provided at one end of the conductive piston away from the movable ball.

[0013] Optionally, a conductive slot matched with the conductive hemisphere is provided at one end of the slide cylinder away from the elastic rope, a first conductive sheet is provided on the side wall of the conductive slot, and a second conductive sheet is provided on the side wall of the slide cylinder close to the conductive slot.

[0014] Optionally, the first conductive sheet is externally connected to a terminal of a photosensor via a wire, the other terminal of the photosensor is connected to one pole of a power supply, and the second conductive sheet is connected to the other pole of the power supply.

[0015] Optionally, the photosensor is externally connected to a control unit, and the control unit is electrically connected to the electric heating structure for controlling the turning on or off of the electric heating structure.

[0016] Optionally, both sides of the slide cylinder are provided with through holes, and a photosensitive sensor is installed at one end of the through hole away from the iron piece, and the photosensitive sensor is opposite to one side of the through hole.

[0017] When the present invention is used, the radiation heating rod works for a period of time, and part of the heat is conducted through the iron part to melt the hot melt adhesive. At this time, the hot melt adhesive becomes transparent after melting. When the upper part of the radiation heating rod is rotated to the downward side, the movable ball is driven to rotate under the action of the iron part. When the movable ball squeezes the conductive piston, the conductive hemisphere partially contacts the first conductive sheet of the conductive groove, and the bottom of the conductive piston contacts the second conductive sheet at the same time. Since the first conductive sheet is connected to a terminal of a photosensor through a wire, the other terminal of the photosensor is connected to one pole of a power supply, and the second conductive sheet is connected to the other pole of the power supply, the photosensor is powered on and starts working. Since the radiation heating rod is rotated at a certain angle, a light source is emitted into the perforation, passes through the movable hole and enters the photosensor. At this time, the photosensor receives a light signal, generates an electrical signal and transmits it to the control unit. At this time, the control unit automatically turns off the electric heating structure for a period of time.

[0018] Beneficial Effects

[0019] 1. The present invention provides a safety automatic control component, which is used to automatically shut down the electric heating structure for a period of time when the radiant heating rod is manually rotated, thereby reducing the risk of serious burns. In this way, the radiant heating rod is stopped from working, which improves the safety of use.

[0020] 2. In the present invention, the safety automatic control component can only be activated after the radiant heating rod has been working for a period of time to melt the hot melt adhesive and the radiant heating rod is rotated to a certain angle so that the conductive hemisphere partially contacts the first conductive sheet of the conductive groove. This can prevent the safety automatic control component from being triggered when the radiant heating rod is turned off or touched by mistake, thereby automatically shutting down the electric heating structure for a period of time, thereby reducing the risk of more serious burns. In this way, the radiant heating rod can be stopped from working, thereby improving the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] The technical solution adopted by the present invention is as follows:

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention discloses a radiant heater, comprising: a body 1, a long strip-shaped mounting groove 2 is provided on the body, a rotatable radiant heating rod 3 is installed in the mounting groove, an electric heating structure 4 is arranged in the radiant heating rod, a safety automatic control component 5 is installed on the side wall of the mounting groove, the safety automatic control component is externally connected to a control unit 6, and the safety automatic control component is used to automatically shut down the electric heating structure for a period of time when the radiant heating rod is manually rotated.

[0033] The safety automatic control component includes an iron part 7 installed in the radiant heating rod. An arc-shaped transparent slide 8 is provided in the side wall of the installation groove, and a magnetic movable ball 9 is provided in the slide. The movable ball is connected to one end of the slide by an elastic rope 10, and the iron part is used to drive the movable ball to move. A movable hole 11 is provided in the movable ball, and the movable hole runs through the left and right sides of the movable hole. The outer wall of the movable hole is made of transparent material. Slides are installed on both sides of the radiant heating rod of this embodiment, so that the safety automatic control component can be triggered no matter how the radiant heating rod is rotated. The side of the slide away from the movable ball is filled with compressed gas. At this time, the movable ball will also be partially filled with gas.

[0034] The slide cylinder is provided with a conductive piston 12, and the slide cylinder near the moving ball is filled with a certain amount of hot melt adhesive, which is transparent after melting and white after solidification. The conductive piston is provided with a conductive hemisphere 13 at one end away from the moving ball.

[0035] The end of the slide cylinder away from the elastic rope is provided with a conductive slot 14 adapted to the conductive hemisphere, the side wall of the conductive slot is provided with a first conductive sheet 15, and the side wall of the slide cylinder close to the conductive slot is provided with a second conductive sheet 16. The first conductive sheet is connected to a terminal of a photosensitive sensor 17 through a wire, the other terminal of the photosensitive sensor is connected to one pole of a power supply, and the second conductive sheet is connected to the other pole of the power supply.

[0036] The photosensitive sensor is externally connected to a control unit, and the control unit is electrically connected to the electric heating structure to control the opening or closing of the electric heating structure. Perforations 18 are provided on both sides of the slide tube, and a photosensitive sensor is installed at one end of the perforation away from the iron part, and the photosensitive sensor is facing one side of the perforation.

[0037] The control unit of the present invention may adopt a computer system or a PLC (Programmable Logic Controller).

[0038] When this embodiment is implemented, the radiant heating rod works for a period of time, and part of the heat is conducted through the iron part to melt the hot melt adhesive. At this time, the hot melt adhesive becomes transparent after melting. When the upper part of the radiant heating rod is rotated to the downward side, the movable ball adsorbed with the iron part is driven to rotate under the action of the iron part. When the movable ball squeezes the conductive piston, the conductive hemisphere partially contacts the first conductive sheet of the conductive groove, and the bottom of the conductive piston contacts the second conductive sheet at the same time. Since the first conductive sheet is connected to a terminal of the photosensor through a wire, the other terminal of the photosensor is connected to one pole of the power supply, and the second conductive sheet is connected to the other pole of the power supply, the photosensor is powered on and starts working. Since the radiant heating rod is rotated at a certain angle, a light source is projected into the perforation and enters the photosensor through the movable hole. At this time, the photosensor receives a light signal, and the photosensor generates an electrical signal and transmits it to the control unit. At this time, the control unit automatically turns off the electric heating structure for a period of time. As the gas in the slide expands due to heat, the internal air pressure increases. When the conductive piston rotates to contact the first conductive sheet of the conductive slot, the gas in the slide is compressed. When the iron part is separated from the movable ball, the conductive piston rebounds due to the action of the gas.
