Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, in particular to a thermal evaporation mechanism and a thermal humidifier. Background Art

[0002] A humidifier is a household appliance commonly used to increase the humidity of the environment. Common humidifiers on the market are usually divided into cold humidifiers and hot humidifiers. Among them, the hot humidifier directly heats and boils the water in the humidifier through a heating element, causing it to boil continuously to produce steam, which is then sent out in the form of a spray. However, in existing hot humidifiers, since a heating element (such as a heating wire, etc.) is used to directly heat the water, the water will constantly make a gurgling sound during use, causing the hot humidifier product to be noisy during use, affecting the user's experience; at the same time, during the use of the hot humidifier, the heating element needs to heat all the water in the humidifier, and the volume of water that needs to be heated is large, and the heating efficiency is low, which will also affect the user's experience. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a thermal evaporation mechanism. After the thermal evaporation mechanism is used in a thermal humidifier, the noise generated when the thermal humidifier is used can be effectively reduced and the heating efficiency can be improved, thereby improving the user experience. At the same time, the thermal evaporation mechanism has good sealing performance, which can effectively prevent the heating element from directly contacting water and affecting the use effect.

[0004] Another object of the present invention is to provide a thermal humidifier having the thermal evaporation mechanism.

[0005] The technical solution of the utility model is: a heat evaporation mechanism, including a heating element, a heating element bracket, evaporation cotton and a sealing ring, the heating element is installed on the heating element bracket, a sealing ring is provided at the bottom of the heating element, the sealing ring is provided between the heating element and the heating element bracket, the evaporation cotton is provided outside the heating element, and the bottom of the evaporation cotton extends to below the sealing ring. When the evaporation mechanism is used, the heating element is set above the water level in the container, the heating element bracket plays a supporting role, the sealing ring can effectively play a waterproof and heat-insulating role, the evaporation cotton is used to absorb the water in the container, and then the evaporation cotton is heated by the heating element to evaporate the absorbed water, forming a hot spray and discharged from the container, thereby achieving the effect of thermal humidification. Since the heating element will not be in direct contact with water, noise can be avoided during the heating process, and the scale generation on the heating element can also be reduced.

[0006] The bottom of the heating element is provided with a first threaded hole portion protruding downward, and the top of the heating element bracket is provided with a second threaded hole portion protruding upward. The first threaded hole portion is connected to the second threaded hole portion and is locked by screws.

[0007] An annular gap is also provided between the outer wall of the heating element and the first threaded hole, and the sealing ring is stepped, the upper part of the sealing ring is embedded in the annular gap, and the lower part of the sealing ring is located between the heating element and the heating element bracket. This structure can form a good sealing structure at the bottom of the heating element, avoiding direct contact between the heating element and water, and playing a waterproof role. At the same time, the sealing ring can also prevent the heating element from contacting other components except the evaporating cotton, and play an effective heat insulation role.

[0008] The heating element is in the shape of a mushroom head as a whole, and the outer surface of the heating element is coated with a Teflon paint coating. The material of the heating element can be die-cast aluminum, and a heating tube is arranged inside it (the specific structure can be the same as the existing heating elements on the market). The surface coating can make the adhesion of scale weaker. After the humidifier has been running for a period of time, the scale produced can be washed or wiped with clean water, which is conducive to scale cleaning. At the same time, the mushroom-shaped heating element has an arched top. When water vapor condenses and falls on the heating element, the arched arc surface is conducive to the water flowing down, and it is not easy to accumulate and produce scale.

[0009] The bottom of the evaporating cotton is folded outward into an L shape. That is, the main body of the evaporating cotton is columnar, and a plurality of extensions extending downward are arranged at the bottom of the main body of the evaporating cotton, and each extension is evenly and intermittently distributed along the circumference of the evaporating cotton, and there is a gap between two adjacent extensions. After the evaporating cotton is installed, each extension is folded outward, so that the lower part of the evaporating cotton forms an L shape. This structural method can effectively increase the absorption area of ​​the evaporating cotton and improve its evaporation efficiency.

[0010] Another technical solution of the utility model is: a thermal humidifier with the above-mentioned thermal evaporation mechanism, the thermal evaporation mechanism is installed below the mist outlet of the thermal humidifier, the heating element is located above the water level as a whole, and the lower part of the evaporating cotton extends below the water level. Ensure that the heating element does not come into direct contact with water. After the evaporating cotton absorbs water, the heating element heats the evaporating cotton, so that the water adsorbed on the evaporating cotton evaporates to form thermal spray, and finally discharged from the mist outlet. The mist outlet is set in the upper cover of the thermal humidifier.

[0011] The heating element bracket is arranged on the outside of the shell of the thermal humidifier, the heating element, the sealing ring and the evaporating cotton are arranged on the inside of the shell of the thermal humidifier, the heating element, the shell of the humidifier and the heating element bracket are arranged in sequence from top to bottom and are connected by screw locking, and the sealing ring is arranged at the junction of the heating element and the shell.

[0012] The thermal humidifier includes an evaporation chamber and a water storage chamber arranged side by side, a partition is provided between the evaporation chamber and the water storage chamber, a water inlet is provided at the lower part of the partition, the evaporation chamber and the water storage chamber are connected through the water inlet, and a float assembly is also provided at the water inlet. Among them, the upper cover of the thermal humidifier covers the evaporation chamber and the water storage chamber, the upper cover above the evaporation chamber corresponds to the mist outlet, and the upper cover above the water storage chamber corresponds to the drain outlet or water inlet. The float assembly can adopt a common float assembly on the market, which is used to control the switch of the water inlet. When the water level in the evaporation chamber is too low, the water inlet is opened, and the water storage chamber is used to replenish water. When the water level in the evaporation chamber reaches the upper line, the water inlet is closed to prevent the water in the water storage chamber from continuing to enter the evaporation chamber. On the one hand, it ensures that there is enough water in the evaporation chamber for the evaporating cotton to absorb, and on the other hand, it also ensures that the heating element is always above the water level in the evaporation chamber and is not in direct contact with the water.

[0013] The evaporation chamber is also provided with an air guide tube, the heat evaporation mechanism is provided at the bottom of the evaporation chamber in the air guide tube, and the top of the air guide tube is a mist outlet. The air guide tube and the shell of the thermal humidifier form a double-detachable structure. On the one hand, the air guide tube can guide and collect the formed mist, and on the other hand, it can also protect the heat evaporation mechanism, preventing users from easily contacting the heating element, thereby ensuring the safety of the thermal humidifier product.

[0014] The air guide tube is in a bottle-shaped structure, which has a mist collecting function and is conducive to collecting the water vapor generated inside the air guide tube and then discharging it from the mist outlet.

[0015] When the above-mentioned thermal humidifier is in use, its principle is as follows: in the evaporation chamber, the heating element is located above the water level as a whole to ensure that the heating element is not in direct contact with the water; the lower part of the evaporating cotton extends below the water level; after the evaporating cotton absorbs water, the heating element heats the evaporating cotton to evaporate the water adsorbed on the evaporating cotton to form thermal spray; the thermal spray is collected and guided by the air duct and finally discharged from the mist outlet at the top of the evaporation chamber; during the use of the thermal humidifier, the water level in the evaporation chamber is replenished by the water storage chamber.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the thermal evaporation mechanism and thermal humidifier, after the evaporating cotton absorbs water, the heating element heats the evaporating cotton to evaporate the water to form hot mist, thereby avoiding the noise generated by direct contact between the heating element and water. At the same time, since there is no need to heat a large amount of water at the same time, the heating efficiency and evaporation efficiency can be effectively improved, thereby improving the user experience. At the same time, due to the setting of the sealing ring in the thermal evaporation mechanism, it has good waterproof and heat-insulating effects and good sealing performance, which can effectively avoid direct contact between the heating element and water to affect the use effect.

[0018] In the thermal evaporation mechanism, a mushroom-shaped heating element is used, and a Teflon paint coating is coated on the surface of the heating element, which can make the scale adhesion weaker. After the thermal humidifier has been running for a period of time, the scale generated can be removed by flushing or wiping with clean water, which is conducive to scale cleaning. At the same time, the top of the mushroom-shaped heating element is arched. When water vapor condenses and falls on the heating element, the arched curved surface is conducive to the water flowing downward, and it is not easy to accumulate and generate scale.

[0019] In this thermal humidifier, an air guide tube is also arranged in the evaporation chamber. On the one hand, the air guide tube can guide and collect the formed mist, and on the other hand, it can also protect the thermal evaporation mechanism to prevent the user from easily contacting the heating element, thereby ensuring the safety of the thermal humidifier product.

[0027] The present invention will be further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0028] Example

[0029] This embodiment provides a thermal evaporation mechanism and a thermal humidifier, and its specific structure is as follows Figures 1 to 3 shown.

[0030] This embodiment is a thermal evaporation mechanism, such as Figure 1 or Figure 2As shown, it includes a heating element 1, a heating element bracket 2, evaporating cotton 3 and a sealing ring 4. The heating element is installed on the heating element bracket. A sealing ring is provided at the bottom of the heating element, and the sealing ring is provided between the heating element and the heating element bracket. The evaporating cotton is provided outside the heating element, and the bottom of the evaporating cotton extends to below the sealing ring. When the evaporation mechanism is in use, the heating element is placed above the water level in the container (i.e., the thermal humidifier described below). The heating element bracket plays a supporting role. The sealing ring can effectively play a role of waterproofing and heat insulation. The evaporating cotton absorbs the water in the container, and then the evaporating cotton is heated by the heating element to evaporate the absorbed water, forming a hot spray that is discharged from the container, thereby achieving the effect of thermal humidification. Since the heating element will not be in direct contact with water, noise can be avoided during the heating process, and the formation of scale on the heating element can also be reduced. As shown Figure 2 As shown, a first threaded hole portion 1-1 protruding downward is provided at the bottom of the heating element, and a second threaded hole portion 2-1 protruding upward is provided at the top of the heating element bracket. The first threaded hole portion is connected to the second threaded hole portion and is locked and connected by a screw 5. An annular gap 1-2 is also provided between the outer wall of the heating element and the first threaded hole portion. The sealing ring is stepped, and the upper part of the sealing ring is embedded in the annular gap, and the lower part of the sealing ring is located between the heating element and the heating element bracket. This structure can form a good sealing structure at the bottom of the heating element, avoiding direct contact between the heating element and water, thereby playing a waterproof role. At the same time, the sealing ring can also prevent the heating element from contacting other components except the evaporating cotton, thereby playing an effective heat insulating role. Figure 4 As shown, the heating element is in the shape of a mushroom head as a whole, and the outer surface of the heating element is coated with Teflon paint. The material of the heating element can be die-cast aluminum, and a heating tube is arranged inside it (the specific structure can be the same as the existing heating elements on the market). The surface coating can be set to make the adhesion of scale weaker. After the humidifier has been running for a period of time, the scale produced can be washed or wiped with clean water to remove it, which is conducive to scale cleaning. At the same time, the top of the mushroom-shaped heating element is arched. When water vapor condenses and falls on the heating element, the arched arc surface is conducive to the water flowing downward, and it is not easy to accumulate and produce scale. The bottom of the evaporating cotton is folded outward into an L shape, that is, Figure 2 As shown, the main body of the evaporating cotton is columnar, and a plurality of extension parts 3-1 extending downward are provided at the bottom of the main body of the evaporating cotton. The extension parts are evenly and intermittently distributed along the circumferential direction of the evaporating cotton, and there is a gap between two adjacent extension parts. After the evaporating cotton is installed, the extension parts are folded outward, so that the lower part of the evaporating cotton forms an L shape. This structural method can effectively increase the absorption area of ​​the evaporating cotton and improve its evaporation efficiency.

Ensure that the heating element does not come into direct contact with water. After the evaporating cotton absorbs water, the heating element heats the evaporating cotton, so that the water adsorbed on the evaporating cotton evaporates to form a thermal spray, and finally is discharged from the mist outlet. The mist outlet is arranged in the upper cover of the thermal humidifier. The heating element bracket is arranged on the outside of the shell 8 of the thermal humidifier, and the heating element, the sealing ring and the evaporating cotton are arranged on the inside of the shell of the thermal humidifier. The heating element, the shell of the humidifier and the heating element bracket are arranged in sequence from top to bottom and connected by screw locking. The sealing ring is arranged at the junction of the heating element and the shell. The thermal humidifier includes an evaporation chamber 9 and a water storage chamber 10 arranged side by side.

The evaporation chamber and the water storage chamber are connected through the water inlet hole, and a float assembly 13 is also provided at the water inlet hole. Among them, the upper cover 14 of the thermal humidifier covers the evaporation chamber and the water storage chamber. The upper cover above the evaporation chamber corresponds to the mist outlet, and the upper cover above the water storage chamber corresponds to the drain outlet or water inlet of the water storage chamber. The float assembly can adopt the common float assembly on the market, which is used to control the switch of the water inlet hole. When the water level in the evaporation chamber is too low, the water inlet hole is opened and the water storage chamber is used to replenish water. When the water level in the evaporation chamber reaches the upper line, the water inlet hole is closed to prevent the water in the water storage chamber from continuing to enter the evaporation chamber. On the one hand, it ensures that there is enough water in the evaporation chamber for the evaporation cotton to absorb, and on the other hand, it also ensures that the heating element is always above the water level in the evaporation chamber and is not in direct contact with water. An air duct 15 is also provided in the evaporation chamber.

The air duct is a bottle-shaped structure. The bottle-shaped structure has a fog collecting function, which is conducive to collecting the water vapor generated inside the air duct and then discharging it from the fog outlet.

[0032] When installing the above-mentioned thermal humidifier, Figure 3 As shown, the heating element and the sealing ring are first fixedly installed in the shell of the thermal humidifier. The sealing ring at the bottom of the heating element is used for waterproofing and heat insulation; then the evaporating cotton is sleeved on the outer periphery of the heating element, and the bottom of the evaporating cotton is folded into an L shape.
