Description

Technical Field

[0001] This utility model relates to a humidifier and heater, belonging to the field of household appliance technology. Background Technology

[0002] In winter, especially in northern China, the weather is cold and dry. Most heaters on the market today focus solely on raising the indoor temperature, and their structural design is mostly centered around how to generate heat efficiently and quickly. However, these heaters can further exacerbate the dryness of the indoor air during use, and can easily cause problems such as dry skin and respiratory discomfort for users.

[0003] Therefore, some heating devices with humidification functions have begun to exist in the existing technology. However, they often simply integrate the humidification and heating components into one housing without achieving complete separation of the humidification air duct and the heating air duct. This design can easily lead to water vapor corrosion of the heating electronic components, shorten the service life of the device, reduce the safety and stability of use, and cause the humidification and heating processes to interfere with each other, affecting their respective performance and making it difficult to achieve the ideal humidification and heating effect.

[0004] In addition, existing equipment of this type is inadequate in terms of safety protection measures, lacking multiple protection mechanisms such as tipping power-off, disconnection power-off, and dry burning overheat protection, which cannot fully guarantee the safety of users during use.

[0005] Therefore, the urgent problem to be solved in this field is how to design a humidifier and heater that can effectively integrate humidification and heating functions, ensure safe and stable operation, and give full play to the performance of both. Summary of the Invention

The spring rod extends downward through the movable cavity formed by the opening in the middle of the water tank and the upward bulge, and then extends out of the lower end face of the water tank.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the humidifying air duct has two structures and settings. One is that the humidifying air duct has a bifurcated structure in the middle, so that the humidifying air duct forms two parallel air outlets set on both sides of the blowing air duct.

[0013] Another type has an "L" shaped cross-section for the humidifying air duct, with the air outlet of the humidifying air duct located below the blowing air duct.

Both ends of the spring abut against the lower end face of the limiting rib and the fixing cap, respectively.

[0015] Furthermore, the air inlet edge of the humidifying air duct extends outward to form a sealing edge covering the upper surface of the water tank.

[0016] Furthermore, it also includes a sealed flame-retardant cover installed on the inner wall of the housing, which connects the air outlet and the air outlet of the humidification duct and the air outlet of the blower duct.

[0017] The heating mechanism has a flame-retardant outer casing.

[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0032] like Figure 1-2As shown, the humidifier heater consists of a main unit 100 detachably mounted on top of a water tank 200. The main unit 100 includes a housing 110, a humidifying air duct 120, a blowing air duct 130, a circuit board 140, and a humidifying fan 150, a blowing fan 160, a heating mechanism 170 (optionally, the heating mechanism 170 can be an electric heating wire), and a linkage switch mechanism 180, all electrically connected to the circuit board 140. The humidifying fan 150 has a waterproof structure. An air inlet 111 and an air outlet 112 are respectively opened on the side wall of the housing 110. The circuit board 140 extends out of the housing 110 through wires to form a power plug. The water tank 200 has a water-absorbing filter element 210 and a water tank vent 220 on its side wall. When in use, water is added to the water tank 200, and the water-absorbing filter element 210 will be wetted by the water. The water-absorbing filter element 210 is breathable, and the airflow can carry away the moisture and increase the humidity of the airflow.

[0033] The air inlet of the humidifying air duct 120 faces the water tank 200 and the air outlet faces the air outlet 112. The humidifying fan 150 is located at the air inlet of the humidifying air duct 120. After the humidifying fan 150 is working, it draws air from the water tank 200 and generates negative pressure in the water tank 200. The dry air enters the water tank 200 through the water tank air hole 220, passes through the water absorption filter element 210 to increase the air humidity, and then enters the air inlet of the humidifying air duct 120 upwards through the humidifying fan 150. After passing through the air outlet and the air outlet 112 in sequence, it is discharged to achieve humidification.

[0034] The air inlet of the air blower duct 130 faces the air inlet 111 and the air outlet faces the air outlet 112. The air blower fan 160 is located at the air inlet of the air blower duct 130, and the heating mechanism 170 is located at the air outlet of the air blower duct 130. After the heating fan is working, it draws air through the air inlet 111, and after passing through the air inlet of the air blower duct 130 and the heating mechanism 170, it forms hot air, which is then discharged from the air outlet and the air outlet 112 to achieve heating.

[0035] The linkage switch mechanism 180 includes a mechanical tilt switch 181 and a spring rod. The mechanical tilt switch 181 is treated with waterproof adhesive and is mounted on a fixed bracket 114 on the lower end face of the housing 110, and movably abuts against the spring rod. The spring rod extends downward through the movable cavity 230 formed by the opening in the middle of the water tank 200 and protrudes upward, and then extends out of the lower end face of the water tank 200. After the equipment is placed, the part of the spring rod protruding from the lower end face of the water tank 200 is pressurized and bulges upward, touching the mechanical tilt switch 181 to power on the equipment. When the equipment is tilted or picked up, the spring rod moves downward under the elastic force of the spring 184, moving away from the mechanical tilt switch 181, disconnecting the circuit, and stopping the equipment from working, thereby ensuring safe use.

[0036] In another embodiment of this utility model, such as Figure 3As shown, the spring rod includes a movable rod 182 and a spring 184. One end of the movable rod 182 is fixedly connected to a fixing cap 183 and extends out of the lower end face of the water tank 200. The other end is movably abutted against the mechanical tilt switch 181. The middle section of the movable rod 182 has a limiting protrusion 185. The limiting protrusion 185 is movably abutted against the upper end face of the limiting rib (not shown in the figure, which is located between the limiting protrusion 185 and the spring 184 after installation) on the inner wall of the movable cavity 230. The two ends of the spring 184 abut against the lower end face of the limiting rib and the fixing cap 183, respectively. The limiting protrusion 185 and the limiting rib cooperate to limit the movable rod 182 and prevent it from falling. The limiting rib, the spring 184 and the fixing cap 183 cooperate to realize the relative position change of the spring rod and the mechanical tilt switch 181 when the equipment is picked up and put down.

[0037] In another embodiment of this utility model, the edge of the air inlet of the humidifying air duct 120 extends outward to form a sealing edge 121 covering the upper surface of the water tank 200, which serves as a seal to prevent water vapor below from corroding the internal circuitry of the main unit 100.

[0038] In another embodiment of this utility model, a sealing flame-retardant cover 190 is also provided on the inner wall of the housing 110. The sealing flame-retardant cover 190 connects the air outlet 112 and the air outlet of the humidification duct 120 and the air outlet of the blowing duct 130, ensuring that the airflow direction is constant and avoiding safety problems caused by heating.

[0039] In another embodiment of this utility model, the heating mechanism 170 has a flame-retardant sleeve 171 on the outside, which avoids safety problems caused by heating.

[0040] In another embodiment of this utility model, a disinfection lamp 113 electrically connected to the circuit board 140 is also included. The disinfection lamp 113 is mounted on the fixing frame 114 and the light source is directed toward the water tank 200. The disinfection lamp 113 is treated with waterproof and water-proof adhesive and shines downwards onto the water surface to achieve the sterilization effect.

[0041] In another embodiment of this utility model, a water level observation window 240 is provided on the side wall of the water tank 200.

[0042] In another embodiment of this utility model, a temperature and humidity sensor and / or display screen are also included. The temperature and humidity sensor and / or display screen are electrically connected to the circuit board 140. The temperature and humidity sensor is set at the air inlet 111 to identify indoor humidity and temperature. The display screen is embedded in the housing 110 to display implementation data information, such as working status, current temperature or humidity, etc. Example

[0043] like Figure 4As shown, the humidifying air duct 120 has a bifurcated structure in the middle, which makes the humidifying air duct 120 form two air outlets that are arranged in parallel on both sides of the blowing air duct 130. Example

[0044] like Figure 5 As shown, the humidifying air duct 120 has an "L" shaped cross section, and the air outlet of the humidifying air duct 120 is located below the blowing air duct 130.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
