Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a desktop heater. Background Art

[0002] A heater is a device used for heating. There are many types of heaters. The most common electric heater is a heating device that uses electricity as energy for heating. There are also many forms of heaters, including desktop, vertical, and wall-mounted. Among them, the desktop heater is small and exquisite, with smooth vertical lines. It is usually placed on the table or on the ground for use. The overall use process is flexible and convenient.

[0003] For example, a bar-type heater disclosed in announcement number CN209013321U includes a base, a tabletop, a connecting rod, a heating pipe, a mesh cover and a spherical top cover with an opening downward. The base and the connecting rod are used to support the heating device, and a tabletop is set in the middle of the connecting rod, which is used in restaurants, bars, hotels or clubs. Although the heater under this structure meets the needs of desktop use scenarios, considering the current demand for energy saving, whether it is a desktop heater for home use or a bar, it is possible that people forget to turn off the heater, especially in public places. People who use the heater are particularly prone to forget to turn off the heater in time when leaving the heater use area. This not only wastes electricity, but also in some application scenarios, for the heater that is forgotten to be turned off, because the heat energy emitted by the heater is much greater than that of ordinary lighting lamps, it is very likely that the heater will cause a safety accident due to long-term operation due to forgetting to turn it off.

[0004] Therefore, for the desktop heaters generally used in the prior art, it is necessary to further optimize their overall structure in terms of energy saving and safety during use. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0029] See also Figures 1 to 4As shown, this embodiment provides a desktop heater, including: a heating part and a support base connected to the heating part and suitable for being placed on a desktop; wherein the heating part includes a cover shell 11, a reflector 12 fixed to the cover shell 11, an annular heating element 13 arranged on the reflector 12, and a protective mesh cover 14 matched with one end of the cover shell 11 facing the support frame. The support base includes a base 21 and a support column 22 connected to the base 21, and a connecting base 23 connected to one end of the support column 22 away from the base 21; the connecting base 23 is connected to the protective mesh cover 14; a circuit board electrically connected to the annular heating element 13 is arranged in the base 21. Of course, it should be noted that a button switch 31 electrically connected to the circuit board for controlling the on and off state of the annular heating element 13 is also arranged on the base 21.

[0030] On the basis of the above structure, the present embodiment is also provided with an infrared sensor on the circuit board, and an infrared lens 32 corresponding to the infrared sensor is provided on the side wall of the base 21. More specifically, an assembly hole for installing the infrared lens 32 is provided on the side wall of the base 21. Based on this structure, when the infrared ray senses the human body temperature within 3-5 meters, the annular heating element 13 starts to work, and the annular heating element 13 will continue to work as long as it senses the human body, and will automatically turn off about 30 seconds after the person leaves. In other words, the present embodiment can identify the human body infrared through the infrared sensor and automatically control the switch of the desktop heater through the circuit board, thereby avoiding the situation where the heater is forgotten to be turned off, thereby improving the safety of the overall desktop heater during use, and avoiding the waste of electric energy.

[0031] Next, an optional situation is given in conjunction with the accompanying drawings. The base 21 is circular or rectangular; and the assembly hole is located on the circumferential side wall of the base 21. The circumferential side wall is also provided with a through hole suitable for passing the power line 33 electrically connected to the circuit board. The assembly hole and the through hole are respectively located on both sides of the support column 22. Under this structure, when the practical heater is used, the infrared lens 32 is placed toward the human body, and the power line 33 is connected to the power supply from the side facing away from the infrared lens 32, so that the use process of the infrared lens 32 and the power line 33 are independent of each other and do not interfere with each other.

[0032] Considering that the heater of this embodiment is generally placed on a table for use, in order to facilitate charging of a mobile phone or tablet, in an optional implementation, a USB port 35 is also provided on the base 21 .

[0033] Next, an optional implementation is given by way of example in conjunction with the accompanying drawings. The reflector 12 includes a trumpet-shaped main reflector 121 and an extension cover 122 connected to the circumferential edge of the main reflector 121; the extension cover 122 is formed by turning the circumferential edge of the main reflector 121 outward toward the side of the support column 22. The cooperation between the main reflector 121 and the extension cover 122 can effectively expand the heat radiation area of ​​the annular heating element 13 after heating, thereby effectively improving the heating effect of the overall desktop heater.

[0034] It should be noted that the annular heating element 13 is connected to the shell of the reflector 12 through a plurality of steel wire fixing frames arranged at intervals. The annular heating element 13 is fixed to the shell of the reflector 12 using steel wire frames, which is not only convenient for assembly, but also does not affect the heat radiation area of ​​the shell of the reflector 12, and can maximize the heat radiation efficiency.

[0035] On the basis of the above structure, in further detail, the steel wire fixing frame used in this embodiment includes a connecting ear 51 connected to the main reflector 121 and a ferrule portion 52 integrally connected to the connecting ear 51 and suitable for being mounted on the annular heating element 13. The connecting ear 51 is fixed to the main reflector 121 by screws. Here, the cooperation between the ferrule portion 52 and the annular heating element 13 can be achieved by deformation of the ferrule portion 52, that is, the ferrule portion 52 is formed by bending the steel wire. Since the steel wire has good bending performance, the operation of achieving cooperation with the annular heating element 13 by bending the steel wire is convenient and efficient.

[0036] In summary, for the desktop heater of this embodiment, the safety during use is improved, and the problem of energy waste due to forgetting to turn off the heater can be avoided.
