Detailed Description

The following are only embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.

In the present invention, the words describing the directional relationship such as "front", "back", "inner", "outer" are only used for convenience of description of the embodiment, and are not considered as limitations of the present invention. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The fixed connection mode comprises but is not limited to a connection mode known in the prior art, such as welding, screwing, clamping, interference fit, integral forming and the like; the number of the plurality is more than one.

Fig. 1 to 4 show an embodiment of the present invention. This embodiment provides a fan heater for warmhouse booth, including casing 1, all be equipped with a round hole around this casing 1 and be exhaust vent and fresh air inlet, install fan 11 through four banding fixed plates 12 in exhaust vent department, fixed plate 12 one end and fan 11's motor fixed connection promptly, the other end and casing 1 fixed connection. A water inlet pipe 6 with a second valve 5 and a water outlet pipe 3 with a first valve 2 are arranged on one side wall of the shell 1 from bottom to top, and a coiled pipe 13 with two ends respectively fixedly connected with the water inlet pipe 6 and the water outlet pipe 3 is arranged in the shell.

A plurality of air deflectors 10 are vertically arranged in the shell 1 at the front of the coiled pipe 13, namely between the air outlet hole and the coiled pipe. As shown in fig. 3 and fig. 4, the upper and lower ends of the air deflector 10 are rotatably connected to the housing 1 through a rotating shaft 17, a fixing block 16 is further fixedly mounted on the lower portion of the air deflector 10, and a first connecting lug 18 is mounted on a side wall of the fixing block 16 facing the inside of the housing 1.
