[0034] See Figures 1-3 According to some embodiments of this application, this application provides an electric heater, including a housing, a heating element, and a humidification mechanism 50. The housing 10 has an air inlet 11 and a mist outlet 13. The heating element 30 is disposed inside the housing 10 corresponding to the air inlet 11, and the humidification mechanism 50 is disposed inside the housing 10 corresponding to the mist outlet 13. It includes a humidification component 60 and a fan 80. The humidification component 60 is used to atomize liquid to form mist, and the fan 80 is disposed on the side of the humidification component 60 facing the heating element 30. The fan 80 is used to drive the external airflow from the air inlet 11 through the heating element 30 to form hot air. The fan 80 is also used to drive the hot air through the interior of the humidification component 60 and carry the mist out through the mist outlet 13.

[0035] In other words, by placing the fan 80 on the side of the humidifying component 60 facing the heating element 30, the fan 80 is close to the heating element 30. When the fan 80 is working, it can drive the external airflow from the air inlet 11 to the heating element 30 to form hot air. Then, the hot air flows into the humidifying mechanism 50, where it comes into contact with the mist formed inside the humidifying component 60, increasing the mist temperature and thus improving the atomization effect. Furthermore, after the hot air enters the humidifying component 60, the liquid inside is also heated, further improving the atomization efficiency and atomization volume, thereby enhancing the atomization effect.

[0036] Furthermore, the humidifying component 60 and the heating element 30 are arranged along the first direction. In the first direction, the fan 80 is located between the humidifying component 60 and the heating element 30, and the air inlet side of the fan 80 faces the heating element 30. In this way, when the fan 80 is working, it can drive the airflow from the air inlet 11 through the heating element 30, and then flow to its own air inlet side to form hot air.

[0037] Optionally, the first direction is the direction in which the electric heater 100 extends longitudinally, and the humidification mechanism 50 and the heating element 30 are arranged in the direction in which the electric heater 100 extends longitudinally.

[0038] According to some embodiments of this application, the humidification assembly 60 includes a housing 62, a water tank 64, and an atomizer 66. The water tank 64 is fitted inside the housing 62, and a water tank 67 is defined between the water tank 64 and the housing 62. The atomizer 66 is disposed on the housing 62 and extends at least partially into the water tank 67. In this way, water in the water tank 64 can flow to the water tank 67, and the atomizer 66 can atomize the water in the water tank 67 into mist.

[0039] Furthermore, the fan 80 is located on the side of the housing 62 facing away from the water tank 67, and the air outlet side of the fan 80 is connected to the water tank 67. When the fan 80 is working, it drives the airflow to flow through the heating element 30 to form hot air, and then drives the hot air to flow into the water tank 67. On the one hand, the hot air can carry the mist formed above the water tank 67 out while heating the mist temperature and improving the atomization efficiency. On the other hand, the hot air can heat the temperature of the water in the water tank 67, which can further improve the atomization efficiency and atomization amount, so that the electric heater 100 has better humidification performance.

[0040] Furthermore, an air duct 621 adjacent to the water tank 67 is formed on the housing 62. One end of the air duct 621 is connected to the water tank 67, and the other end of the air duct 621 is equipped with a fan 80. Thus, the fan 80 and the water tank 67 are connected through the air duct 621. When the fan 80 is working, the hot air generated flows to the water tank 67 through the air duct 621.

[0041] Optionally, a transition channel 623 adjacent to the air duct 621 is also formed on the housing 62. The end of the air duct 621 away from the fan 80 is connected to the transition channel 623, and the end of the water tank 67 away from the fan 80 is also connected to the transition channel 623. In this way, the water tank 67 and the air duct 621 both have openings on the same side that are connected to the transition channel 623, so that the water tank 67 and the air duct 621 can be connected through the transition channel 623.

[0042] In some specific embodiments, the air duct 621 and the transition channel 623 are both extended along a second direction that intersects with the first direction, for example, along the vertical direction of the electric heater 100.

[0043] See Figures 2-5 According to some embodiments of this application, the housing 62 is fitted inside the outer shell 10, and an air inlet gap 70 is defined between the housing 62 and the outer shell 10. The air inlet gap 70 is in fluid communication between the heating element 30 and the fan 80. In this way, after the fan 80 is installed outside the housing 62 and the humidification mechanism 50 is fitted inside the outer shell 10, the air inlet gap 70 is reserved between the housing 62 and the outer shell 10. When the fan 80 is working, the hot air passing through the heating element 30 can flow to the air inlet side of the fan 80, ensuring the continuity of the airflow channel.

[0044] According to some embodiments of this application, the outer casing 10 has a first bottom wall 15 opposite to the mist outlet 13. A first water-blocking rib 151 is provided on the first bottom wall 15. The first water-blocking rib 151 is located between the fan 80 and the heating element 30, and the first water-blocking rib 151 is spaced apart from the air inlet side of the fan 80 to form an air inlet gap 70. In this way, the first water-blocking rib 151 is provided on the first bottom wall 15 of the outer casing 10. The first water-blocking rib 151 is located between the fan 80 and the heating element 30. When water in the tilted water tank 67 of the electric heater 100 flows along the air duct 621 to the fan 80, the first water-blocking rib 151 can block the water flow, prevent the water from flowing to the heating element 30, prevent the heating element 30 from malfunctioning after water enters it, and improve the safety performance of the user.

[0045] At the same time, an air inlet gap 70 is formed between the first water baffle 151 and the fan 80. The hot air passing through the heating element 30 can flow to the fan 80 through the air inlet gap 70 on one side of the first water baffle 151. The first water baffle 151 will not block the air inlet side of the fan 80, ensuring smooth airflow.

[0046] Furthermore, the housing 62 includes a second bottom wall 63 facing the first bottom wall 15, the second bottom wall 63 being spaced apart from the first bottom wall 15, and a second water-blocking rib 631 located between the first water-blocking rib 151 and the fan 80 is provided on the second bottom wall 63; the second water-blocking rib 631 blocks the end of the fan 80 near the second bottom wall 63 on the air inlet side, and is spaced apart from the first water-blocking rib 151. In this way, by providing the second water-blocking rib 631 at the end of the fan 80 near the second bottom wall 63, the second water-blocking rib 631 blocks the end of the fan 80 near the second bottom wall 63, preventing liquid in the air duct 621 from flowing out from the side of the fan 80 near the second bottom wall 63, further preventing liquid from flowing towards the heating element 30, and further improving the safety performance for users.

[0047] Meanwhile, the first water-blocking rib 151 and the second water-blocking rib 631 are spaced apart from each other, allowing the airflow to flow through the gap between the first water-blocking rib 151 and the second water-blocking rib 631 and then flow to the air inlet side of the fan 80.

[0048] In some specific embodiments, the first water-blocking rib 151 extends towards the second bottom wall 63 and is spaced apart from the second bottom wall 63, and the second water-blocking rib 631 extends towards the first bottom wall 15 and is spaced apart from the first bottom wall 15. Thus, when the fan 80 is operating, the hot air generated by the heating element 30 first flows through the gap between the first water-blocking rib 151 and the second bottom wall 63 to the air inlet gap 70, and then flows through the gap between the second water-blocking rib 631 and the first bottom wall 15 to the fan 80, thereby achieving fluid communication between the air inlet gap 70, the heating element 30, and the fan 80.

[0049] Furthermore, along the first direction, the orthographic projection of the first water-blocking rib 151 toward the second water-blocking rib 631 covers at least a portion of the second water-blocking rib 631, that is, the free end of the first water-blocking rib 151 is spaced outside the free end of the second water-blocking rib 631, and the free ends of the first water-blocking rib 151 and the free ends of the second water-blocking rib 631 cooperate to block each other, effectively blocking the water along the entire height direction from the first bottom wall 15 to the second bottom wall 63.

[0050] Furthermore, in the second direction from the first bottom wall 15 to the second bottom wall 63, which intersects with the first direction, the height of the first water-blocking rib 151 is greater than the height of the second water-blocking rib 631. In other words, the first water-blocking rib 151 is higher. Thus, when the electric heater 100 is tilted, the water in the water tank 67 flows from the air duct 621 to the fan 80 and the first bottom wall 15, and can be blocked by the higher first water-blocking rib 151. This prevents the water-blocking ability from being weakened due to the lower height of the first water-blocking rib. In this way, the higher first water-blocking rib 151 can effectively block the water flow from the first bottom wall 15 to the heating element 30.

[0051] According to some embodiments of this application, a drain outlet 155 is provided on the first bottom wall 15 corresponding to the fan 80, and the drain outlet 155 is located on the side of the first water baffle 151 facing away from the heating element 30. In this way, the water flow blocked above the first bottom wall 15 by the first water baffle 151 can be discharged from the outer casing 10 through the drain outlet 155, preventing water from accumulating in the outer casing 10 and entering the electrical components, thereby further improving the safety performance of the electric heater 100.

[0052] According to some embodiments of this application, a third water-blocking rib 153 is further provided on the first bottom wall 15, and a fourth water-blocking rib 633 is further provided on the second bottom wall 63. Both the third water-blocking rib 153 and the fourth water-blocking rib 633 surround the outer periphery of the unit and are located on the side of the fan 80 away from the heating element 30. The third water-blocking rib 153 is fitted over the fourth water-blocking rib 633 on the outer side facing away from the fan 80. Thus, by providing the third water-blocking rib 153 and the fourth water-blocking rib 633 on the side of the fan 80 away from the heating element 30, water is also blocked from the outer periphery of the fan 80 facing away from the heating element 30, preventing water flowing from the air duct 621 from flowing into other components around the fan 80, further improving the safety performance of the various electrical components in the electric heater 100.

[0053] Furthermore, the first water-blocking rib 151 blocks the first side of the fan 80 facing the heating element 30, the fourth water-blocking rib 633 is arranged in a semi-circular shape around the remaining outer periphery of the fan 80 excluding the first side, and the third water-blocking rib 153 is arranged around at least part of the outer periphery of the fourth water-blocking rib 633. In this way, by the fourth water-blocking rib 633 surrounding the other outer periphery of the fan 80 outside the first side, the combination of the fourth water-blocking rib 633 and the first water-blocking rib 151 can block the entire outer periphery of the fan 80, preventing the water flowing into the air duct 621 from flowing towards the fan 80 and then flowing around the fan 80, thus preventing water from entering the electrical components around the fan 80 and further improving the waterproof performance of the electrical components.

[0054] Meanwhile, the third water-blocking rib 153 is arranged around the fourth water-blocking rib 633. On the one hand, the cooperation between the third water-blocking rib 153 and the fourth water-blocking rib 633 can guide the installation of the limiting housing 62 and the outer shell 10. On the other hand, the cooperation between the third water-blocking rib 153 and the fourth water-blocking rib 633 can block the gap between the fourth water-blocking rib 633 and the first bottom wall 15, preventing water from flowing out from the gap between the fourth water-blocking rib 633 and the first bottom wall 15, thus further enhancing the water-blocking performance.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
