Problems solved by technology
[0004] The purpose of the present invention is to solve the technical problem that the existing axial-flow cooling and heating circulation fan has a large amount of heating air mixed with unheated cold air, resulting in an unsatisfactory somatosensory effect. Therefore, the present invention provides an air duct that can The variable cooling and heating circulation fan can not only realize the adjustment of the cold air volume, but also improve the heating effect

Embodiment Construction
[0038] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0039] Such as figure 1 and figure 2 As shown, the air duct variable cooling and heating circulation fan of the present invention usually includes a fuselage 1 and a base 2, wherein the fuselage 1 includes a rear net cover 11, a driving device 12, a heating component 13, fan blades 14 and a front net 17. A detachable and fixed connection is formed between the front net 17 and the airtight annular air duct 112, which has the functions of safety protection and air outlet; the driving device 12 and the heating ...

The invention discloses an air duct variable type cooling and heating recirculating fan. The recirculating fan comprises a rear mesh enclosure, a driving device, a heating assembly and fan blades, wherein the driving device and the heating assembly are arranged in the rear mesh enclosure, a rotating shaft of the driving device penetrates through the heating assembly and then is connected with the fan blades, an annular radial air inlet channel is further arranged on a portion, between the fan blades and the heating assembly, of the rear mesh enclosure, a closed annular air duct is formed at the front end of the rear mesh enclosure and axially connected with the radial air inlet channel in a front-back direction, an annular air blocking ring is arranged at the radial air inlet channel in a sleeved mode, an axial size of the annular air blocking ring is larger than or equal to an axial size of the radial air inlet channel, and the annular air blocking ring can axially move in and out of a position of the radial air inlet channel to control opening and closing of the radial air inlet channel. According to the recirculating fan, by arranging the annular air blocking ring, the radial air inlet channel can be opened and closed by means of the annular air blocking ring, cold air and warm air are switched for use, the phenomenon that the warm air is mixed with the cold air when only the warm air is required is avoided, and the body feeling of a user is improved.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air duct variable cooling and heating circulation fan. Background technique [0002] Heaters or fans are essential appliances in modern households. At present, there are either a single heater or a single fan on the market, but there are very few products that can truly combine the functions of heater heating and fan blowing. It is a cooling and heating type circulation fan. The cooling and heating circulation fan can be used not only as a heater, but also as a fan. Due to the fixed product structure of the cooling and heating circulation fan, the axial flow fan blades enter the air synchronously in both radial and axial directions, and the air intake volume is large. When warm air needs to be blown out, the hot air blown out is also mixed with cold air, especially around the entire air outlet net, which makes the body feel not very ideal. [0003] For example, the...
