[0034] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art.

[0035] To make the technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0036] An electric heater provided by an embodiment of the present application, such as Figure 1 , Figure 2 and Figure 3As shown, the electric heater includes a light source 1 and a water mist flow channel 100. The water mist flow channel 100 has an outlet section 101. Among them, the light source 1 is located inside the water mist flow channel 100, and the light emitted by the light source 1 exits from the outlet section 101. Among them, the extension line of the optical axis of the light source 1 towards the outlet section 101 is blocked by the inner wall of the water mist flow channel 100.

[0037] It can be understood that the light emitted by the light source 1 exits from the outlet section 101 and can be mixed with the water mist to form a flame effect. The extension line of the optical axis of the light source 1 towards the outlet section 101 is blocked by the inner wall of the water mist flow channel 100, which is beneficial to avoiding the direct irradiation of the optical axis of the light source 1 into the human eye and can reduce the interference to the user.

[0038] In the embodiment of the present application, the optical axis can refer to the center line of the light beam, and the optical axis of the light source 1 refers to the center line of the light beam emitted by the light source 1. When the light source 1 is a spotlight, all the light rays in the light beam emitted by it are substantially parallel and have substantially the same direction. When the light source 1 is an LED lamp, the cross-section of the light beam emitted by the light source 1 in the irradiation direction is fan-shaped, so the optical axis can be regarded as the angular bisector of the first included angle α of the fan. Exemplarily, the irradiation range can be a semi-circle.

[0039] In the embodiment of the present application, the illumination intensity in the direction towards which the optical axis of the light source 1 is directed is stronger than that in other directions. Therefore, setting the first included angle α between the optical axis of the light source 1 and the extension direction of the outlet section 101 is beneficial to the light rays along the direction of the optical axis. After one or more reflections on the wall surface of the outlet section 101, they then leave the water mist flow channel 100 through the outlet section 101. In this way, the illumination intensity of the light source 1 can be weakened, thereby reducing the interference to the user.

[0040] In the embodiment of the present application, when the water mist passes through the water mist flow channel 100, under the illumination of the light rays of the light source 1, it can form a flame effect when leaving the water mist flow channel 100.

[0041] In the embodiment of the present application, the light source 1 can have its own power supply and have the ability to emit light, or it can also emit light by connecting to an external power supply.

[0042] In the embodiment of the present application, the light source 1 can be a lamp such as an LED lamp (Light-Emitting Diode) or a halogen lamp.

[0043] In the embodiment of the present application, the water mist can enter the surrounding environment through the water mist flow channel 100 to increase the humidity of the surrounding environment. The water mist can be formed by dispersing a liquid such as water into numerous tiny droplets through devices such as atomizing nozzles and atomizers. Among them, the water mist can be driven by a blower to pass through the water mist flow channel 100 and then enter the surrounding environment.

[0044] In the embodiments of the present application, the electric heater may include a water tank, which can store water for atomization and supply the atomization generator to atomize into water mist.

[0045] In the embodiments of the present application, when the water mist passes through the water mist flow channel 100, under the illumination of the light of the light source 1, a flame effect can be formed when leaving the water mist flow channel 100.

[0046] In some embodiments of the present application, the orthographic projection of the light source 1 on the projection plane coincides or is separated from at least a part of the orthographic projection of the outlet section 101 on the projection plane, and the projection plane is a plane perpendicular to the extension direction of the outlet section 101. The extension direction of the outlet section 101 is as Figure 2 shown.

[0047] It can be understood that the water mist flow channel 100 can allow the water mist to pass through. The water mist leaves the electric heater of the present application through the outlet section 101, thereby increasing the humidity of the surrounding environment. The light source 1 is close to the outlet section 101, which can indicate the diffusion direction of the water mist. The orthographic projection of the light source 1 on the projection plane is at least partially separated from the orthographic projection of the outlet section 101 on the projection plane, which is beneficial to reducing the situation that the light emitted by the light source 1 directly irradiates the user through the outlet section 101, and can reduce the interference of the light source 1 to the user.

[0048] In the embodiments of the present application, the light emitted by the light source 1 can directly pass through the water mist flow channel 100 and irradiate outward. The orthographic projection of the light source 1 on the projection plane is at least partially separated from the orthographic projection of the outlet section 101 on the projection plane, and the projection plane is a plane perpendicular to the extension direction of the outlet section 101. In this way, it is beneficial for the light emitted by the light source 1 to be blocked by the outlet section 101, and the blocked light cannot directly pass through the water mist flow channel 100, or needs to be reflected multiple times to leave the water mist flow channel 100. Since part of the light cannot directly irradiate the user's eyes, the problem of the light source 1 being dazzling and interfering with the user can be reduced.

[0049] In some embodiments of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, the light source 1 is located inside the water mist flow channel 100 and is close to the outlet section 101. The optical axis of the light source 1 intersects with the extension direction of the outlet section 101 and forms a first included angle α.

[0050] It can be understood that the water mist flow channel 100 can allow the water mist to pass through. The water mist leaves the electric heater of the present application through the outlet section 101, thereby increasing the humidity of the surrounding environment. The light source 1 is close to the outlet section 101, which can indicate the diffusion direction of the water mist. The optical axis of the light source 1 forms a first included angle α with the extension direction of the outlet section 101, which is beneficial for the light of the light source 1 to directly irradiate on the wall surface of the outlet section 101, and after reflection, enter the user's field of view, thereby reducing the interference of the light source 1 to the user.

[0051] In some embodiments of the present application, as Figure 1 , Figure 2 and Figure 3 shown, wherein the orthographic projection of the light source 1 on the projection plane coincides or is separated from the orthographic projection of the outlet section 101 on the projection plane. The projection plane is a plane perpendicular to the extending direction of the outlet section 101, and the optical axis of the light source 1 intersects with the extending direction of the outlet section 101 to form a first included angle α.

[0052] It can be understood that the water mist flow channel 100 can allow the water mist to pass through. The water mist leaves the electric heater of the present application through the outlet section 101, thereby increasing the humidity of the surrounding environment. The light source 1 is close to the outlet section 101, which can indicate the diffusion direction of the water mist. The orthographic projection of the light source 1 on the projection plane is at least partially separated from the orthographic projection of the outlet section 101 on the projection plane, which is beneficial to reducing the situation that the light emitted by the light source 1 directly irradiates the user through the outlet section 101, and can reduce the interference of the light source 1 to the user. The optical axis of the light source 1 forms a first included angle α with the extending direction of the outlet section 101, which is beneficial to the light of the light source 1 directly irradiating on the wall surface of the outlet section 101, forming reflection and then entering the user's field of vision, and reducing the interference of the light source 1 to the user.

[0053] In some embodiments of the present application, as Figure 2 shown, the electric heater includes a power supply member 2. The light source 1 is located in the water mist flow channel 100, and the power supply member 2 is electrically connected to the light source 1. The light source 1 is located on the side of the power supply member 2 facing the outlet section 101.

[0054] It can be understood that the power supply member 2 can provide support and electric energy for the light source 1, enabling the light source 1 to emit light. The light source 1 is located on the side of the power supply member 2 facing the outlet section 101, which is beneficial for the light emitted by it to pass through the water mist flow channel 100.

[0055] In an embodiment of the present application, the power supply member 2 can be a structure such as a circuit board, and the light source 1 is welded to the circuit board through pins to form an electrical connection.

[0056] In an embodiment of the present application, the light source 1 has two pins, and the two pins are respectively welded to the circuit board to form an electrical connection. Among them, the length of one pin is greater than the length of the other pin, so that the optical axis of the light source 1 can form a first included angle α with the extending direction of the outlet section 101.

[0057] In some embodiments of the present application, as Figure 4 shown, the number of the light sources 1 is at least two columns, and each column of the light sources 1 in the at least two columns is arranged at intervals along the length direction of the power supply member 2.

[0058] It can be understood that such a setting is conducive to the uniform distribution of the light emitted by the light source 1 within the outlet section 101, which is conducive to the light source 1 indicating the diffusion direction of the water mist.

[0059] In the embodiments of the present application, the number of the light sources 1 can be 3 columns, 4 columns or other numbers of columns.

[0060] In some embodiments of the present application, as Figure 4 shown, the number of the light sources 1 is two columns, the optical axis of each light source 1 forms a second included angle β with the width direction of the power supply member 2, and the second included angle β formed by the optical axis of each light source 1 in each column of the light sources 1 with the width direction of the power supply member 2 faces the side where the other column of the light sources 1 of the power supply member 2 is located. The outlet section 101 is located between the two columns of the light sources 1, and the value range of the second included angle β is (0, 90] degrees.

[0061] It can be understood that such a setting is conducive to the light emitted by the two columns of the light sources 1 passing through the outlet section 101 and leaving the water mist flow channel 100, so that the indication effect of the light source 1 on the diffusion direction of the water mist can be improved.

[0062] In the embodiments of the present application, the value of the second included angle β can be 15, 30, 45, 60, 75 or 90, or other values within the value range.

[0063] In some embodiments of the present application, as Figure 4 shown, two columns of the light sources 1 among at least two columns of the light sources 1 are arranged staggeredly along the length direction of the power supply member 2.

[0064] It can be understood that the two columns of the light sources 1 arranged staggeredly are conducive to dispersing the light emitted by each light source 1, so that the uniformity of the light distribution within the outlet section 101 can be improved, and further the interference caused by the direct light to the user can be reduced.

[0065] In some embodiments of the present application, as Figure 4 shown, there is a distance D between the light source 1 and the central axis of the power supply member 2, and the value range of the distance D is (0, 3.5] mm.

[0066] It can be understood that within the above range, by aligning the central axis of the power supply member 2 with the axis of the outlet section 101, the light source 1 can be staggered relative to the outlet section 101 and blocked by the outlet section 101, so as to weaken the light entering the user's field of view.

[0067] In the embodiments of the present application, the value of the distance D can be 0.5, 1.0, 1.5, 2, 2.5, 3.0 or 3.5, or other values within the value range.

[0068] In the embodiments of the present application, the distance D between the central axis of the light source 1 and the power supply member 2 may refer to the distance between the starting point of the optical axis on the light source 1 and the central axis of the power supply member 2.

[0069] In the embodiments of the present application, when the power supply member 2 is rectangular, the central axis of the power supply member 2 may refer to the line that is parallel to the arrangement direction of a row of light sources 1 and divides the power supply member 2 into two congruent rectangles.

[0070] In some embodiments of the present application, as Figure 2 shown, the water mist flow channel 100 includes an inlet section 102, the inlet section 102 is communicated with the outlet section 101, and the cross-sectional area of the inlet section 102 is larger than the cross-sectional area of the outlet section 101.

[0071] It can be understood that the inlet section 102 with a larger cross-sectional area is conducive to the passage of water mist, and the water mist passes through and leaves the water mist flow channel 100 through the outlet section 101. At the same time, it is beneficial to maintain the flow rate of the water mist passing through the outlet section 101.

[0072] In some embodiments of the present application, as Figure 3 shown, the electric heater includes a bracket 3, the bracket 3 is located in the inlet section 102 and is connected to the side wall of the inlet section 102, and the power supply member 2 is located on the side of the bracket 3 facing the inlet section 102.

[0073] It can be understood that the bracket 3 can support the power supply member 2. During assembly, the power supply member 2 can be first installed on the bracket 3, and then the power supply member 2 can be installed in the inlet section 102 through the bracket 3. In this way, it is beneficial for the electric heater of the present application to directly use a rectangular circuit board as the power supply member 2, reducing the modification required for the power supply member 2 to be installed in the inlet section 102.

[0074] In the embodiments of the present application, the power supply member 2 can be connected to the circuit board by means of bolts, bonding or welding, etc.

[0075] In the embodiments of the present application, the bracket 3 can be connected to the side wall of the inlet section 102 by means of clamping, bonding or welding, etc.

[0076] In some embodiments of the present application, the value range of the first included angle α is (0, 90] degrees.

[0077] It can be understood that within the above range, it is beneficial for the light of the light source 1 to leave the water mist flow channel 100 after one or more reflections and enter the user's field of vision. In this way, the illumination intensity of the light source 1 can be reduced.

[0078] In the embodiments of the present application, the value of the first included angle α can be 15, 30, 45, 60, 75 or 90, or other values within the value range.

[0079] In some embodiments of the present application, as Figure 1 shown, the electric heater includes an upper cover 4 and a guiding flow channel 200. The upper cover 4 is located at one end of the outlet section 101 away from the light source 1. The guiding flow channel 200 and the water mist flow channel 100 are respectively located on opposite sides of the upper cover 4, and the guiding flow channel 200 is communicated with the water mist flow channel 100.

[0080] It can be understood that the upper cover 4 can support the guiding flow channel 200, and at the same time can partially block the structure forming the water mist flow channel 100, reducing the situation that the water mist flow channel 100 is damaged by external force extrusion. The guiding flow channel 200 can guide the diffusion direction of the water mist, which is beneficial to the water mist entering the surrounding environment.

[0081] In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.

[0082] Those skilled in the art will readily think of other embodiments of the present application after considering the specification and practicing the present application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application. The specification and embodiments are only regarded as exemplary.
