As shown in fig. 1 and 2, in one embodiment, a purified electrothermal film warmer 10 is provided, which comprises a housing 11, a partition 12 is arranged in the housing 11, and the space enclosed by the housing 11 is divided into a heating cavity 111 and an air outlet cavity 112. An electric heating film 15 is arranged in the heating cavity 111 and used for heating air entering the heating cavity 111.

The air outlet cavity 112 is located at the bottom of the housing 11. An air inlet 113 is formed on the portion of the housing 11 forming the heating cavity 111, and an air outlet 114 is formed on the portion of the housing 11 forming the air outlet cavity 112. That is, the air heated from the purified electrothermal film warmer 10 is discharged into the room from the air outlet 114 at the bottom of the housing 11, so that the hot air is sufficiently filled in the active region of the human body. And the radiation heat generated by the electric heating film 15 can be transmitted out through the air inlet 113. Thereby improving the heating effect of the purified electrothermal film warmer 10 as a whole. Specifically, the emissivity of the electrothermal film 15 is 0.7-0.9.

Specifically, the partition 12 is provided with a ventilation hole, and the housing 11 is provided therein with an air extracting member 14 for guiding the hot air in the heating chamber 111 into the air outlet chamber 112 through the ventilation hole. Indoor air enters the heating cavity 111 from the air inlet 113 under the action of the air draft piece 14, and the heated air enters the air outlet cavity 112 from the air vent and is then exhausted into the indoor from the air outlet 114 of the air outlet cavity 112. And the ventilation hole is provided with an air purification device 13, so that the heated air is filtered and purified by the air purification device 13 in the process of entering the air outlet cavity 112 from the heating cavity 111, the situation that a small amount of harmful peculiar smell generated in the process of supplying heat by the electric heating film 15 is discharged into a room is avoided, and the purpose of improving the indoor air quality in heating is achieved.

Further specifically, air purification device 13 includes primary filter screen, long-term HEPA filter screen and active carbon particle filter screen, primary filter screen, long-term HEPA filter screen and active carbon particle filter screen stack gradually the setting. The primary filter screen is used for filtering large-particle impurities, dust, hair and the like. The long-acting HEPA filter screen is used for filtering and purifying substances such as PM2.5, bacteria, pollen and the like. The activated carbon particle filter screen is mainly used for adsorbing and purifying harmful gas molecules in air.

The air inlet 113 and the air outlet 114 on the housing 11 may be formed by arranging the side wall of the housing 11 as a grill, so that each through hole of the grill for forming the heating cavity 111 constitutes the air inlet 113, and each through hole of the grill for forming the air outlet cavity 112 constitutes the air outlet 114. For example, as shown in fig. 1, an air outlet grille 115 and an air inlet grille 116 are disposed on a side wall of the housing 11, the air outlet 114 is formed by through holes of the air outlet grille 115, and the air inlet 113 is formed by through holes of the air inlet grille 116. The heated air can be discharged into the room from various directions through the outlet port 114. The radiant heat generated by the electric heating film 15 can be transmitted into the room from all directions through the air inlet gateway. Further improve heating experience.

And the air cleaning device 13 is arranged at a ventilation hole, and specifically, the air cleaning device 13 can be arranged in the heating cavity 111 or the air outlet cavity 112 and intercepted at the ventilation hole; it is also possible to shield the air cleaning device 13 completely in the ventilation hole so that the hot air is filtered and cleaned by the air cleaning device 13 when passing through the ventilation hole.

The extractor 14 is primarily used to provide power for the circulation of air. And the air extracting member 14 may be disposed adjacent to the air cleaning device 13 in order to allow the hot air to rapidly and efficiently pass through the air cleaning device 13. For example, as shown in fig. 2, the ventilator 14 includes a centrifugal fan having a fan blade 141 stacked on the air cleaner 13.

Further, in one embodiment, as shown in fig. 2, a first heating channel 151 is formed between a first side of the electric heating film 15 and the housing 11, and a second heating channel 152 is formed on a second side of the electric heating film 15.

Therefore, the indoor air entering from the air inlet 113 firstly enters the second heating channel 152 after being heated by the electric heating film 15 in the first heating channel 151, and then is heated by the electric heating film 15 in the second channel, so that the time for the air to exchange heat in the heating cavity 111 is prolonged, the heat generated by the electric heating film 15 is fully transferred to the air, and the heating efficiency is improved.

Specifically, the electric heating film 15 may be a plate or a cylinder. For example, when the electric heating film 15 is a plate, the air inlet 113 may be disposed on a side wall of the housing 11 opposite to the first side surface, and the ventilation opening is disposed on the spacer 12 at a side of the second side surface of the electric heating film 15.

When the through hole is formed by a plurality of small holes at intervals, the through hole may be formed at a portion of the separator 12 between the electric heating film 15 and the guide member 16. Alternatively, when the through hole includes only one large hole, the diameter of the vent hole is at least larger than the outer diameter of the flow guide 16, so that the hot air in the second heating passage 152 can enter the air outlet cavity 112 through the vent hole.

For example, as shown in fig. 2, in one embodiment, the separator 12 is an annular plate, the outer ring of which is connected to the side wall of the housing 11, and the inner ring of which constitutes the ventilation hole. The electric heating film 15 encloses the ventilation hole inside. The aperture of the vent hole may be the same as the inner diameter of the electric heating film 15. The air cleaning device 13 completely shields the vent hole, so that the air in the second heating channel 152 only enters the air outlet cavity 112 after passing through the air cleaning device 13, and the bottom end of the flow guide 16 is connected or abutted to the air cleaning device 13. The hot air in the second heating channel 152 can pass through the portion of the ventilation hole between the air guide 16 and the electric heating film 15, and in the process, the hot air is filtered and purified by the air purifying device 13.
