[0002] Fan heaters are used for circulating air heating. They can be used independently for heating, generally to supplement the insufficient heating capacity of radiators or to utilize radiators for heating, with the remaining heat load handled by the fan heater. Fan heaters are used as indoor air heating devices. Currently, fan heaters usually heat the air directly. Indoor air contains dust and cannot be purified or filtered, which can easily cause discomfort to users. In addition, fan heaters usually swing horizontally and cannot adjust the vertical angle according to heating needs. Therefore, a new type of fan heater needs to be designed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please refer to Figures 1-6 As shown, this utility model provides a novel air heater, including a housing 1, a cover plate 2 bolted to the rear of the housing 1, a fan 3 for drawing air to circulate inside the housing 1, a heating element for heating air inside the housing 1, a filter for purifying air on the other side of the cover plate 2, a support frame 4 mounted on the outer side of the housing 1 near the bottom, a locking element between the housing 1 and the support frame 4, a base 5 rotatably mounted on the bottom of the support frame 4, a connecting piece 6 between the base 5 and the support frame 4, and the locking element can adjust the airflow direction angle of the housing 1.

[0024] The cover plate 2 has multiple through holes, and the fan 3 can drive outside air into the housing 1 through the cover plate 2. The heating element inside the housing 1 can heat the air and discharge it. The filter installed on the inside of the cover plate 2 can purify and filter the dust in the air, preventing dust or impurities in the air from being discharged through the housing 1 and causing discomfort to the user. The support frame 4 has a U-shaped cross section and can support the housing 1. The support frame 4 can support the housing 1 while rotating on the base 5 through the connecting piece 6. The housing 1 can rotate in the vertical direction within the support frame 4. The locking piece can automatically lock and fix the adjustment direction of the housing 1, improving the stability of the adjustment housing 1 when the angle changes in the vertical direction.

[0025] Specifically, the heating element includes a heating frame 7 that is bolted to the inside of the housing 1. A heating tube 8 is fixedly installed inside the heating frame 7. Multiple fins 9 are evenly arranged and fixedly connected to both sides of the heating frame 7. The heating tube 8 is serpentine. Two sets of guide plates 18 are fixedly connected to the inside of the heating frame 7 and to both sides of the heating tube 8. The two sets of guide plates 18 are staggered.

[0026] The heating frame 7 has multiple through holes. The heating tube 8 inside the heating frame 7 can heat the air. The multiple fins 9 on both sides of the heating frame 7 can increase the contact area between the heating frame 7 and the air. The heat generated by the heating tube 8 preheats the air through the multiple fins 9. The two sets of guide plates 18 inside the heating frame 7 can guide the air and extend the air flow path, so that the heating tube 8 can fully heat the air. The multiple through holes on both sides of the heating frame 7 can facilitate the air flow and also facilitate the air to be discharged through the shell 1 after heating, thereby improving the efficiency and practicality of the shell 1 in heating and warming.

[0027] More specifically, the filter element includes a limiting frame 10 on one side of the cover plate 2 and near both ends. A filter element 11 for dust prevention and air filtration is slidably connected to the inner side of the limiting frame 10. An adsorption pad 19 is embedded in the inner side of the filter element 11, and the adsorption pad 19 is filled with adsorbent and desiccant.

[0028] It should be added that the limiting frame 10 has an L-shaped cross section. The limiting frame 10 can limit and fix the filter element 11, so as to facilitate the disassembly and cleaning or replacement of the filter element 11. The adsorbent and desiccant filled in the adsorption pad 19 can adsorb, dry and purify the dust or humid air in the air again, so as to avoid the impurities or dust in the air from causing discomfort to the user.

[0029] Furthermore, the locking mechanism includes fixed shafts 12 fixedly connected to both sides of the housing 1, fixed rings 13 fixedly connected to both sides of the support frame 4, four circumferentially arranged movable cavities 14 opening inside the fixed rings 13, an elastic frame 15 fixedly connected to one side inside the movable cavity 14, a locking ball 16 fixedly connected to the bottom of the elastic frame 15, multiple circumferentially arranged locking grooves 17 opening outside the fixed shafts 12, two spring pieces 20 fixedly connected inside the elastic frame 15, and the locking ball 16 slidably connected to the movable cavity 14.

[0030] Furthermore, both the locking ball 16 and the locking groove 17 have arc-shaped cross sections. When the housing 1 rotates and flips within the support frame 4, the housing 1 drives the fixed shaft 12 to rotate within the fixed ring 13. Then, the elastic frame 15 in the movable cavity 14 can squeeze and push the locking ball 16. At the same time, the two spring pieces 20 can squeeze and push the elastic frame 15, so that the four locking balls 16 are respectively embedded in the locking grooves 17 at different positions to limit and fix the housing 1.

[0031] Working principle: First, the housing 1 rotates within the support frame 4. At this time, the elastic frame 15 in the movable cavity 14 squeezes and pushes the locking ball 16. Simultaneously, the two spring plates 20 squeeze and push the elastic frame 15, so that the four locking balls 16 are respectively embedded in the locking grooves 17 at different positions to limit and fix the housing 1. Then, the fan 3 is started, which drives the outside air into the housing 1 through the cover plate 2. The filter element 11 filters and purifies the air for dust prevention. The adsorption pad 19 adsorbs, dries and purifies the dust or humid air in the air again. Then, the two sets of guide plates 18 in the heating frame 7 guide the air and extend the air flow path, so that the heating tube 8 fully heats the air. At the same time, the heated air is discharged through the housing 1.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
