[0033] In order to better understand the purpose, structure and function of the present invention, an electric heater of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 3As shown, the electric heater of the present invention comprises a housing 2 with an air duct, the air inlet of the air duct is arranged on the bottom surface of the housing 2, the air outlet of the air duct is arranged on the side wall of the housing 2, a fan assembly 3 and a heating assembly are arranged in the air duct, and a humidifying assembly 1 is also included, and the humidifying assembly 1 is detachably fixed at the air inlet of the housing 2. By setting the humidifying assembly 1, when the hot air is blown out, the moisture of the humidifying assembly 1 is sucked into the housing 2 and blown out together with the hot air, thereby increasing the humidity of the air, improving the user experience, and having high safety.

[0035] like Figure 2 As shown, the housing 2 is cylindrical, and the humidification component 1 includes a water tank. The water tank and the housing 2 are fixed by a snap-fit ​​structure, so that the humidification component 1 can be detachably fixed to the housing 2. When humidification is not needed, the humidification component 1 can be removed. For example, a plurality of snaps with elastic deformation can be set on the top wall of the water tank, and a plurality of snap holes are set on the bottom surface of the housing 2. When the snaps are inserted into the snap holes, they are deformed, and when the snaps are fully inserted, they are restored, so that the water tank is fixed under the housing 2.

[0036] In addition, the sink and the casing 2 are detachably connected via a locking component, which includes a locking block fixed on the side wall of the sink and a handle hinged on the casing 2, with a U-shaped locking rod hinged in the middle of the handle. Through the cooperation of the locking rod and the locking block, the sink and the casing 2 can also be detachably connected.

[0037] The bottom surface of the housing 2 is provided with a plurality of legs 22, the height of the legs 22 being greater than the axial height of the water tank, so that the humidifying component 1 can smoothly enter the air. In order to facilitate injection molding, the angle between the legs 22 and the axis of the housing 2 is between 0.5°-5°, and the legs 22 have a certain elastic deformation.

[0038] like Figure 3 As shown, the water tank is an annular hollow structure, and the central channel of the water tank forms a channel for air circulation, and the central channel of the water tank is arranged opposite to the air inlet of the housing 2. The water tank is formed by an annular bottom shell 11 and an upper cover 12 that are mutually sleeved, the bottom shell 11 includes an annular bottom plate and side plates connected to the outer periphery of the bottom plate, and the upper cover 12 includes an annular cover plate and an inner plate connected to the inner periphery of the cover plate, the outer periphery of the cover plate overlaps the top of the side plate, and the bottom end of the cover plate is sealed and plugged into the inner circle of the bottom plate.

[0039] like Figure 4As shown, the humidifying component 1 also includes a wet curtain 14 and a support frame for supporting the wet curtain 14. The support frame is fixed on the inner circumference of the bottom shell 11. The support frame includes a plurality of support rings 111 coaxially arranged with the bottom shell 11. Each support ring 111 is connected to the inner circumference of the bottom shell 11 through a connecting rod 112. The connecting rod 112 is evenly distributed along the radial direction of the bottom shell 11. The wet curtain 14 is placed on the support frame. Usually, the humidifying component 1 can be arranged upstream or downstream of the heating component. When the wet curtain 14 is placed downstream of the heating component, the wind from the air outlet first passes through the heating element 4, brings the heat of the heating element 4 into the air, and then takes away the water vapor on the wet curtain 14, thereby playing a role of heating and humidification; preferably, when the humidifying component 1 is placed upstream of the heating component, the wet curtain 14 will not be affected by high temperature.

[0040] In one embodiment, the wet curtain 14 includes wet curtain sheets that are alternately arranged horizontally and vertically in a grid shape. The arrangement direction of the wet curtain sheets is parallel to the air flow direction, so that the grid holes formed by the wet curtain sheets form gaps for air to pass through. A circular enclosure 141 is arranged on the periphery of the wet curtain 14. The enclosure 141 is made of a water-absorbing material. The grid-shaped wet curtain 14 structure fully considers that the water evaporation area is as large as possible, while also reducing wind resistance, so that the humidification amount reaches the maximum value.

[0041] In another embodiment, Figure 7-Figure 9 As shown, the wet curtain 14 includes a circular enclosure 141 made of a water-absorbing material, a plurality of longitudinal wet curtain sheets 142 are arranged in the enclosure 141, and a plurality of transverse wet curtain sheets 143 are arranged between adjacent longitudinal wet curtain sheets 142 and between the enclosure 141 and the wet curtain sheets. In order to enable the wet curtain 14 to humidify evenly, a water absorption strip 144 is arranged in the longitudinal wet curtain sheet 142, and both ends of the water absorption strip 144 are respectively connected to the enclosure 141, and the water absorption capacity of the water absorption strip 144 is greater than that of the wet curtain sheet. After the enclosure 141 absorbs water, the water is radially transmitted to the wet curtain sheets inside the wet curtain 14 through the water absorption strip 144.

[0042] In order to reduce the use of the water absorption strip 144 and ensure the uniformity of the wetting of the wet curtain 14, as Fig.10 As shown, the heights of the water-absorbing strips 144 in adjacent longitudinal wet curtains 14 are different, and the water-absorbing strips 144 are distributed alternately in high and low positions in each longitudinal wet curtain 14. The water-absorbing strips 144 in adjacent longitudinal wet curtains 14 wet the wet curtains 14 from the top and bottom of the transverse wet curtains 14 respectively.

[0043] In order to improve the water absorption of the wet curtain 14, the lateral wet curtains 14 are in wavy, serrated, S-shaped or other curved shapes, and the lateral wet curtains 14 are arranged in an array to increase the surface area of ​​the lateral wet curtains 14.

[0044] like Figure 6As shown, the humidification component 1 also includes a water absorption rod 13 arranged in the water tank. The water absorption rod 13 is L-shaped, and a plurality of fixing holes 121 for the water absorption rod 13 to pass through are provided on the inner plate. One end of the water absorption rod 13 extends to the bottom surface of the water tank, and the other end of the water absorption rod 13 passes through the fixing hole 121 and contacts the enclosure 141. The water absorption rods 13 are evenly distributed in a radial shape. On the one hand, the enclosure 141 plays a supporting role. On the other hand, the water absorption rod 13 transfers the water in the water tank to the enclosure 141, thereby soaking the entire wet curtain 14, and the humidified air is discharged through the fan assembly 3.

[0045] In order to continuously replenish water in the water tank, the humidification assembly 1 also includes a water tank 15 arranged on one side of the water tank, the side wall of the water tank is connected to a water adding tank 113 opening upward, and a water outlet is arranged on the bottom surface of the water tank 15, and the water outlet of the water tank 15 is connected to the top opening of the water adding tank 113. Figure 5 As shown, an L-shaped partition 151 is provided at the water outlet of the water tank 15, and the partition 151 and the side wall of the water tank 15 form a water outlet channel. A baffle 114 connected to the partition 151 is provided in the water adding tank 113, and the bottom end of the baffle 114 extends toward the bottom surface of the water adding tank 113, and the bottom end of the baffle 114 is below the fixing hole 121. A first connecting pipe 152 is provided on the side of the partition 151 away from the water outlet channel, and the end of the first connecting pipe 152 passes through the side wall of the water tank 15 and is connected to the second connecting pipe 153. The second connecting pipe 153 is distributed in the vertical direction, and the free end of the second connecting pipe 153 extends to the top of the water tank 15. A water inlet is provided on the top surface of the water tank 15, and a box cover 154 is sealed at the water inlet. When the liquid level in the water adding tank 113 is lower than the bottom end of the baffle 114, since the first connecting pipe 152 and the second connecting pipe 153 connect the water supply tank to the atmosphere, air enters the water tank 15 and causes the water in the water tank 15 to enter the water supply tank, automatically replenishing the water tank.

[0046] The fan assembly 3 includes a motor and fan blades fixed on the motor drive shaft. The inner wall of the top surface of the casing 2 is provided with a motor bracket for fixing the motor. The motor drive shaft is coaxially arranged with the casing 2. A knob 23 for adjusting the motor speed is provided at the center of the top surface of the casing 2 to achieve bottom air intake and side air outlet.

[0047] In order to fix the heating component, the air outlet of the housing 2 is connected to an air outlet box 21, and an air outlet hole is provided on the side wall of the air outlet box 21 away from the housing 2. The heating component is fixed in the air outlet box 21 so that the hot air can be blown to the user in a directional manner. The heating component includes a heating element 4 and a support frame 41 for fixing the heating element 4. The support frame 41 is a square frame. Blocks for fixing the heating element 4 are respectively provided on the inner wall of the support frame 41. The heating element 4 is fixed in the support frame 41 by snapping.

[0048] In order to fix the heating component in the air outlet box 21, a limiting strip is provided on the inner wall of the air outlet box 21 near the air outlet hole, and also includes an air outlet grille 5, which is fixed at the air outlet hole of the air outlet box 21 by a snap-fit ​​structure. When the heating component is inserted into the air outlet box 21, the air outlet grille 5 and the limiting strip squeeze the support frame 41 from both sides, thereby fixing the heating component in the air outlet box 21.

[0049] The electric heater disassembles the humidifying component 1 at the air inlet of the casing 2 in a detachable manner. When the fan component 3 is in operation, the moisture of the humidifying component 1 is sucked into the casing 2 and blown out together with the hot air, thereby reducing the dryness of the air, improving the user experience, and being highly safe.
