The steam device 10 may further include a direction regulating valve 111, and the direction regulating valve 111 is disposed at the outlet of the duct 11 for regulating the flow direction of the steam discharged from the outlet, thereby regulating the blowing direction of the steam. In some embodiments, the direction-regulating valve 111 may include a plurality of baffles arranged at intervals and a connecting member connecting the plurality of baffles, and the direction of each baffle is changed through the connecting member, for example, as shown in fig. 1 and 2, each baffle is deflected downwards, and the direction of steam blowing is downward; for example, as shown in fig. 3 and 4, each baffle is deflected upward and the direction of the steam blow is upward. Alternatively, in the horizontal direction shown in fig. 1 to 4, the orthographic projection of the plurality of baffles when deflected to the maximum angle covers the orthographic projection (i.e., the orthographic projection of the cross section) of the duct 11.

The duct 11 may have a hollow structure, and its cross-sectional shape includes, but is not limited to, a circle as shown in fig. 1 to 4, and may also be a polygon such as a rectangle. For example, the conduit 11 may be a rectangular body, with a heated thick film 13 disposed on at least one of the six outer surfaces of the conduit 11; the conduit 11 is preferably a cylindrical conduit to facilitate the timely removal of steam from the conduit 11 for rapid heating and humidification.

In some embodiments, the heating thick film 13 may also be disposed on the outer surface of the pipe 11 and thermally connected to the pipe 11, which is beneficial for water and steam to gain more heat. The heating thick film 13 on the pipeline 11 can be independently arranged and independently controlled, and can be seen as that the pipeline 11 is divided into a plurality of areas, each area is provided with the independently controlled heating thick film 13, and the heating thick film 13 on one or part of the pipeline 11 is used for heating water and steam so as to meet the heating and humidifying requirements at a lower temperature; when the heating and humidifying requirements at a high temperature are satisfied, a plurality of or all of the heating thick films 13 may be used simultaneously for heating and humidifying.

The pipe 11 may be made of a material with a suitable thermal expansion coefficient, such as a metal or an alloy, and the pipe 11 is expanded by heat and then is in close thermal contact with the heating thick film 13 and the heat generating coil of the heating thick film 13, which further facilitates the rapid heat transfer to the pipe 11 and the rapid steam generation.

In some embodiments, the second nozzle 122 is disposed at the center of one end of the pipe 11 along the extending direction of the pipe 11, and the range of the water sprayed from the second nozzle 122 is greater than or equal to the diameter of the pipe 11. By centre is understood: taking the cylindrical pipe 11 as an example, the cross section of the pipe 11 is circular, and at the center of the circular shape, the water sprayed by the second spray head 122 can fully contact with the inner wall of the pipe 11, which is beneficial to the timely change of the water into steam.

The heating thick film 13 may be formed on the outer surface of the pipe 11 by a film-coating method or a printing method, and the manufacturing process, shape, material, etc. of the heating thick film 13 are not limited in the embodiments of the present invention.

In some embodiments, referring to fig. 5 and 6, the heating thick film 13 includes an insulating layer 131, a heating coil 132, and an encapsulating layer (not shown). The insulation layer 131 is provided at least on the outer surface of the pipe 11. The insulating layer 131 serves to achieve electrical insulation between the heating coil 132 and the pipe (e.g., the pipe is a metal pipe) 11. The heating coil 132 is disposed on the insulating layer 131 for receiving electricity and generating heat, for example, through a conductive pad. The encapsulation layer is disposed on the insulation layer 131 and covers the heating coil 132, and the encapsulation layer is used to prevent the heating coil 132 from being exposed, so as to prevent the heating coil 132 from being electrically contacted with external conductive electronic components to form a short circuit.

For scenarios where heating is possible on opposite sides of the heated thick film 13, the heated thick film 13 may include a substrate with heating coils 132 and an encapsulation layer disposed on both sides of the substrate. Optionally, an insulating layer 131 is also provided, for example, for a conductive base plate, the insulation between the base plate and the heating coil 132 is achieved by the insulating layer 131 provided therebetween.

The encapsulation layer may be directly formed by a film forming method (for example, a sputtering or evaporation method) using an insulating material to cover the heating coil 132. It should be understood that the encapsulation layer can also be regarded as a thermal insulation layer, which not only covers the heating coil 132, but also has good thermal insulation performance, and is beneficial for transferring more heat generated by the heating coil 132 to the pipeline and avoiding transferring the heat to the outside of the pipeline.

In other embodiments where the outer surface of the conduit 11 in which the heated thick film 13 is disposed is non-conductive, the heated thick film 13 may not be provided with the aforementioned insulating layer 131, but may include a heating coil 132 and an encapsulation layer. Heating coils 132 are provided directly on the outer surface of the pipe 11 for electrical connection and heat generation, for example, by conductive pads. The potting layer is disposed on the outer surface of the pipe 11 and covers the heating coil 132.

The heating thick film 13 may also be provided with conductive pads 134, with the encapsulation layer exposing the conductive pads 134 to allow electrical access to the conductive pads 134. In some embodiments, the surface of the duct 11 may be provided with a terminal plate, one end of which is used for power connection, and the other end of which is electrically connected to the conductive pad 134. In other embodiments, the exposed conductive pads 134 may be directly powered.

It should be understood that the two conductive pads 134 shown in fig. 6 are for exemplary illustration only, and embodiments of the present application do not limit the number of conductive pads 134. For example, the heating thick film 13 may be provided with four conductive pads 134, wherein two of the conductive pads 134 may be used for power connection, and the other two conductive pads 134 may be connected to two pins of the temperature controller 135, respectively, and selectively disconnect the path of the heating coil 132 (between the two conductive pads 134) according to the temperature detected by the temperature controller 135, for example, disconnect the path between the two conductive pads 134 when the heating temperature reaches and exceeds a preset temperature, and maintain the path connection between the two conductive pads 134 below the preset temperature to stop heating.

Referring to fig. 5, 7 to 9, in some embodiments, the steam device 10 further includes a stem 14, the stem 14 is disposed inside the pipe 11, the surface of the stem 14 is provided with an external spiral groove 141, and the external spiral groove 141 and the inner surface of the pipe 11 form a spiral channel. By arranging the core column 14 in the tubular pipe 11, the outer spiral groove 141 of the core column 14 and the inner surface of the tubular pipe 11 form a spiral channel, and the spiral channel prolongs the circulation length and residence time of steam in the pipe 11, which is beneficial to obtaining more heat from the steam, thereby improving the heat exchange efficiency and the heating speed.

Alternatively, each first spray head 121 is disposed in the outer spiral groove 141 in a direction perpendicular to the stem 14 (e.g., in a vertical direction in the orientation shown in fig. 5, 7 to 9), and water sprayed from the first spray head 121 can contact the surface of the stem 14 over a large area, thereby obtaining heat from the stem 14 having good thermal conductivity in time, and facilitating the generation of steam in time.

The stem 14 may be an integrally formed structural member, and specific implementation forms include but are not limited to: silica gel column, ceramic column or plastic column. The outer surface of the stem 14 may be provided with helical projections 142, the helical projections 142 forming an outer helical groove 141. In some embodiments, the distance between the outer spiral grooves 141 decreases gradually along the circulation direction of the steam in the spiral channel, that is, the density of the outer spiral grooves 141 increases gradually closer to the outlet end of the pipe 11, and the larger the circulation length of the steam, the more heat is transferred to the steam per unit time, which is beneficial to increase the heating speed. The density of the outer spiral grooves 141 is smaller closer to the inlet end of the pipe 11, which is beneficial to the rapid circulation of steam inside the pipe 11 and increases the entering amount of the steam.

The steam device 10 may further include a fixing member 143, the fixing member 143 is disposed inside the core column 14, and opposite ends of the fixing member 143 are respectively fixed to sealing structural members (for example, a first joint and a second joint respectively disposed at two ends of the pipeline 11) at two ends of the pipeline 11.

In some embodiments, the fixing element 143 may be a bolt, a nut of the bolt is disposed on a side surface of one of the first joint and the second joint facing away from the other joint and abuts against the side surface, and a screw rod passes through the other joint and is screwed with the nut. Alternatively, a screw having a screw thread provided on the bolt is screwed with the other of the first joint and the second joint. For example, as shown in fig. 8 and 9, the nut is disposed on a side surface of the second joint facing away from the first joint and abuts against the side surface.

In some embodiments, the outer spiral groove 141 is spaced opposite to the inner surface of the pipe 11 along the radial direction of the pipe 11, a certain gap is left between the outer spiral groove 141 and the pipe 11, and the pipe 11 is not directly in heat conduction contact with the stem 14, so that the stem 14 and the outer spiral groove 141 can be prevented from being burned out when the temperature of the pipe 11 is too high, and the service life of the pipe can be prolonged.

In other embodiments, the diameter of the pipe 11 is gradually reduced along the circulation direction of the steam in the spiral passage, and the outer spiral grooves 141 are abutted against the inner surface of the pipe 11.

Embodiments of the present application also provide a heating device, including the steam device 10 manufactured by the method of any of the above embodiments, and thus have corresponding advantages of the steam device 10.

The heating device may be embodied in various specific forms, including but not limited to: air conditioners (such as vehicle air conditioners), electric irons, beauty moisturizing apparatuses, humidifiers, and the like.
