[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] See also Figure 1 and Figure 2 The utility model discloses a humidifying electric heater, which includes a body, a water tank 14 and an atomizing assembly. Specifically, the body is provided with an installation cavity 10, the installation cavity 10 is provided with an electrical connector 13, the water tank 14 is detachably installed in the installation cavity 10, and a conductive member 15 is provided on the outside of the water tank 14. Figure 3 The atomizing assembly includes an atomizing element 16 , which is disposed in the water tank 14 and is electrically connected to a conductive element 15 , which is used to be electrically connected to the electrical connector 13 when the water tank 14 is installed in the installation cavity 10 .

[0036] On the basis of this structure, when using the humidifying electric heater of the utility model, the water tank 14 can be installed in the installation cavity 10 on the machine body, and the conductive member 15 on the outside of the water tank 14 is plugged and connected with the electrical connector 13 in the installation cavity 10, so that after the water tank 14 is installed in the installation cavity 10, the atomizing member 16 performs atomization to humidify the indoor air. After the humidifying electric heater has been used for a period of time, the water tank 14 can be removed from the machine body, and the water tank 14 can be cleaned, watered, and the cotton swab in the water tank 14 can be replaced.

[0037] Therefore, by designing the water tank 14 and the machine body to be detachably connected, the water tank 14 can be easily disassembled and assembled, which is conducive to cleaning and water replacement after the water tank 14 is disassembled, so as to ensure that the water tank 14 is clean. At the same time, the atomizer 16 in the water tank 14 forms a current loop when the conductive member 15 is plugged into the electrical connector 13, so that the atomizer 16 can perform atomization when the water tank 14 is installed on the machine body; when the water tank 14 is separated from the machine body, the current loop is disconnected, and the atomizer 16 stops atomization.

[0038] That is, the circuit between the conductive member 15 and the electrical connector 13 is closed and opened with the installation and removal of the water tank 14, which can ensure electrical safety and prevent leakage. Specifically, when the water tank 14 is not installed or installed improperly, the circuit is in a disconnected state, avoiding the risk of leakage caused by the exposure of live parts inside the equipment; for the atomizer in the humidifying electric heater, it can also prevent the atomizer from idling in a waterless state, thereby avoiding the risk of damage to the atomizer due to overheating. When the circuit is disconnected, even if the device is powered on, it will not cause damage to improperly connected components, thereby protecting the integrity of the circuit and the device. In addition, the user does not need to manually switch the switch or perform complex settings. The device can be turned on and off by simply installing or removing the water tank 14, which improves the convenience of use.

[0039] Further, see Figure 3 The water tank 14 includes a box body 141 and a box cover 142, and the box body 141 and the box cover 142 are detachably connected. The atomizer 16 is arranged in the box body 141, and the box cover 142 is provided with an atomizer hole 144, which is used to guide the mist droplets in the box body 141 to be discharged.

[0040] Based on this structure, an internal thread can be provided on the inner side of the box body 141, and an external thread can be provided on the outer periphery of the lower end of the box cover 142. The box body 141 and the box cover 142 are screwed together through the internal and external threads to achieve a detachable connection. When the atomizer 16 is atomized in the box body 141, the atomized droplets are discharged through the atomization hole 144 on the box cover 142.

[0041] Therefore, the tank cover 142 is arranged on the water tank 14 to prevent external pollutants from contaminating the water in the water tank 14. After the water tank 14 has been used for a period of time, the tank cover 142 can be removed from the tank body 141 for water addition or cleaning operations.

[0042] Further, see Figure 5 The box cover 142 is provided with a receiving chamber 143, and the atomizing assembly includes a control circuit board, and the control circuit board is disposed in the receiving chamber 143. In addition, the conductive member 15 extends from the outside of the box cover 142 into the receiving chamber 143 and is electrically connected to the control circuit board, and the control circuit board is electrically connected to the atomizing member 16.

[0043] On the basis of this structure, when atomizing, the water tank 14 is first installed into the installation cavity 10, and the conductive member 15 and the electrical connector 13 are plugged and connected, and the power supply on the body is started, and the power supply is supplied to the control circuit board through the electrical connector 13, and the control circuit board controls the atomizing member 16 to work and atomize. The control circuit board and the atomizing member 16 are connected by wires, or the electrical connection is achieved by welding the pins of the atomizing member 16 to the control circuit board.

[0044] Since the control circuit board is built into the accommodating cavity 143 of the box body 141, the circuit board can be effectively protected from the influence of the external environment, and the stability and reliability of the circuit board can be improved; at the same time, the external space can be saved, making the device more compact and portable. The control circuit board is connected to the electrical connector 13 through the conductive member 15, which can improve the connection strength and ensure the atomization and humidification effect.

[0045] Furthermore, the atomizing element 16 is an atomizing sheet.

[0046] Specifically, the atomizer sheet can be a microporous atomizer sheet, which is composed of a piezoelectric ceramic sheet and a metal film. The metal film has a microporous area, which is generally perforated by a laser. In the working state, when the current passes through the piezoelectric ceramic sheet, the piezoelectric ceramic sheet vibrates at a high frequency under the action of the electric field. This vibration is transmitted to the liquid through the metal film, so that the liquid is subjected to a strong impact force in the microporous area and decomposed into fine droplets, which are then sprayed into the air to form a mist-like substance.

[0047] In addition, the atomizer sheet can also be a solid hole atomizer sheet (also called a ceramic atomizer sheet), which uses the principle of high-frequency vibration ultrasound to break up the liquid water molecular structure through the high-frequency resonance of the ceramic sheet to produce natural and elegant water mist.

[0048] It should be noted that the atomizer 16 can also be an atomizing nozzle, a compression atomizer, etc., wherein the atomizing nozzle can disperse the liquid into tiny particles under the action of high-pressure or high-speed airflow; the compression atomizer generates a high-speed airflow by compressing air or oxygen, so that the airflow hits a specific obstacle and crushes the liquid into tiny droplets.

[0049] Furthermore, a water absorbing member is provided in the box body 141, and the water absorbing member is in contact with the atomizing sheet.

[0050] Specifically, the water absorbing member is a sponge suction rod. When the atomizing assembly is working, the sponge suction rod absorbs water and then sprays it out from the fine holes in the middle of the atomizing sheet, thereby realizing the spraying function without placing water directly on the atomizing sheet.

[0051] It should be noted that the water absorbent can absorb and store water to prevent water in the water tank 14 from accumulating at the bottom, thereby reducing the possibility of bacterial growth. The water absorbent is replaced after being used for a period of time to ensure the humidification effect and prevent bacterial growth.

[0052] In addition, the absorbent may also be a cotton swab, a towel, etc.

[0053] Furthermore, a sealing member 145 is provided between the box body 141 and the box cover 142 .

[0054] Specifically, the seal 145 can be a sealing ring, a silicone pad, etc. When the box body 141 and the box cover 142 are connected, the seal 145 is squeezed and deformed by the box body 141 and the box cover 142, thereby filling the gap between the box body 141 and the box cover 142. In this way, it can be ensured that the water mist generated in the water tank 14 is guided out through the atomization hole 144 on the box cover 142, ensuring the atomization humidification effect.

[0055] Further, see Figure 6 A receiving cavity 17 is disposed on one side of the installation cavity 10, wherein a connecting hole is disposed on the wall of the receiving cavity 17 facing the installation cavity 10, and the connecting hole connects the receiving cavity 17 with the installation cavity 10. Figure 4 The outer periphery of the connection hole extends toward the installation cavity 10 to form a guide interface 18, and the electrical connector 13 is disposed in the accommodating cavity 17 and located on one side of the connection hole. The guide interface 18 is used to guide the conductive member 15 and the electrical connector 13 to be plugged and connected.

[0056] Based on this structure, when installing the water tank 14, the water tank 14 can be installed from top to bottom in the installation cavity 10, and the conductive part 15 located on one side of the box cover 142 can be inserted into the connecting hole through the guide interface 18 and connected to the electrical connector 13 in the accommodating cavity 17.

[0057] Therefore, the user only needs to insert the conductive member 15 along the guide interface 18 to easily connect with the electrical connector 13 without complicated debugging or calibration process. The setting of the guide interface 18 can guide the conductive member 15 to accurately connect with the electrical connector 13, avoiding connection errors or poor contact problems caused by improper human operation; at the same time, the guide interface 18 can ensure a stable connection between the conductive member 15 and the electrical connector 13, and it is not easy to loosen or fall off even in the case of vibration or movement. In addition, the electrical connector 13 is installed in the accommodating cavity 17, which can prevent the user from directly contacting the live parts when installing or removing the water tank 14, thereby reducing the risk of electric shock.

[0058] Furthermore, the machine body includes a humidifying seat 11 and a heating seat 12. The humidifying seat 11 is arranged above the heating seat 12, and the humidifying seat 11 and the heating seat 12 are detachably connected. The installation cavity 10 is located in the humidifying seat 11; see Figure 7 A heating assembly is disposed in the heating seat 12 , and an air outlet 121 is disposed on the side of the heating seat 12 facing the machine body, and the air outlet 121 is used to guide hot air out.

[0059] Based on this structure, when the humidifying electric heater is powered on, the heating component starts to work and converts electrical energy into thermal energy, which heats the airflow to form a hot air flow, which is discharged into the indoor environment through the air outlet 121, thereby achieving a heating function. In the atomization area of ​​the humidifying seat 11, water is atomized into tiny water mist particles.

[0060] Thus, the atomized water mist can be combined with the hot air blown out from the heating seat 12, so that the humidifying electric heater can provide suitable humidity for the room while heating, and prevent the air from being too dry.

[0061] Furthermore, the heating assembly includes a heating element 19 and an air supply element 20 , wherein the heating element 19 is used to heat the airflow, and the air supply element 20 is used to blow the heated airflow toward the air outlet 121 .

[0062] Specifically, the heating element 19 may be an electric heating wire, a PTC heating element, etc., and the air supply element 20 may be a fan. Through auxiliary devices such as fans, the heated airflow can be quickly exported to the indoor environment to enhance the circulation effect of the hot air.

[0063] Furthermore, the electrical connector 13 in the present invention may adopt spring pins.

[0064] Specifically, the spring pin has good elasticity and can ensure stable contact with the atomizer, and can maintain a good connection even in the case of slight vibration or movement. This stable contact can ensure stable transmission of current and signals, avoiding performance degradation or failure caused by poor contact.

[0065] In addition, the conductive member 15 is made of a conductive material, and specifically can be a columnar body made of metals such as copper, aluminum, silver, gold, and certain alloy materials. By pressing and conducting the columnar conductive member 15 with the spring pin, the internal structure of the device can be simplified, and unnecessary connecting parts and wiring can be reduced. This not only helps to reduce manufacturing costs, but also improves the reliability and maintainability of the device.

[0066] It should be noted that the electrical connector 13 can be a jack, a male connector, etc. in the prior art. When the electrical connector 13 is a jack, the conductive member 15 is a pin, and the pin is plugged and connected with the jack; when the electrical connector 13 is a male connector, the conductive member 15 is a female connector, and the male connector and the female connector are connected and connected.

[0067] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
