Description

Technical Field

[0001] This invention relates to the field of humidifiers, and particularly to an air humidifier. Background Technology

[0002] Existing air humidifiers are mainly categorized into two types based on their humidification method: ultrasonic vibration and heating. Ultrasonic vibration produces cold humidified air, while heating produces hot steam. In practical use, since northern regions are relatively cold, using heated steam is more comfortable than using ultrasonic vibration to produce cold humidified air.

[0003] However, heating the water requires raising it to a high temperature. Therefore, if the humidifier is accidentally knocked over, the water inside may overflow, potentially causing injury to the user due to its high temperature. Thus, an air humidifier that humidifies quickly, is safe to use, and has good insulation between the internal and external heating chambers is needed. Summary of the Invention

[0004] The main objective of this invention is to provide an air humidifier that features fast humidification speed, high safety in use, and good heat insulation between the internal heating chamber and the external heating chamber.

[0005] This invention proposes an air humidifier, including a housing, a top cover, and a heating assembly. The housing is divided into a bottom working chamber and a top heating chamber, and the heating assembly is disposed in the working chamber.

[0006] It also includes a heat insulation component disposed in the heating chamber. The heat insulation component includes a heat insulation component body and a flow guide cover. The heat insulation component body divides the heating chamber into an inner heating chamber and an outer heating chamber. The heat insulation component body is provided with a heat insulation component body through hole. Water in the outer heating chamber enters the inner heating chamber through the heat insulation component body through the heat insulation component body through the through hole.

[0007] The heating component is disposed in the working chamber corresponding to the inner heating chamber. The heating component heats the water in the inner heating chamber and generates hot steam in the inner heating chamber, which then passes through the guide cover and the upper cover to the outside of the air humidifier.

[0008] The heat insulation component body includes an inner heat insulation plate and an outer heat insulation plate. The inner heat insulation plate and the outer heat insulation plate are connected and form a heat insulation groove between them. The heat insulation groove improves the heat insulation capacity of the heat insulation component, thereby increasing the heating speed of the water in the inner heating chamber and reducing the temperature of the water in the outer heating chamber during the air humidification process.

[0009] Preferably, the bottom of the inner heat insulation plate and the bottom of the outer heat insulation plate are connected, and the bottom of the inner heat insulation plate extends to the bottom side to form an annular inner heat insulation plate retaining block;

[0010] The bottom of the inner heating chamber on the inner side of the housing is recessed towards the working chamber to form an inner connecting groove, and the inner heat insulation plate is snapped into the inner connecting groove. This secures the heat insulation assembly within the housing.

[0011] Preferably, the through hole of the heat insulation component body is provided on the inner heat insulation plate block, and the inner heat insulation plate block is higher than the connecting groove inside the shell so that water can smoothly enter the inner heating chamber.

[0012] Preferably, the inner heat insulation plate and the outer heat insulation plate are connected at the top, and a heat insulation cavity is formed in the heat insulation groove between the inner heat insulation plate and the outer heat insulation plate. The heat insulation effect is improved by vacuuming the interior of the heat insulation cavity.

[0013] Preferably, the tops of the inner heat insulation plate and the outer heat insulation plate are bent inward to form a connecting fold for the inner heat insulation plate and a connecting fold for the outer heat insulation plate.

[0014] Preferably, the flow guide cover includes a flow guide cover body and a flow guide tube;

[0015] The bottom of the guide cover body is provided with a lower locking block of the guide cover body. The lower locking block of the guide cover body is inserted into the inner side of the inner heat insulation plate and locked to the inner side of the inner heat insulation plate, thereby locking the guide cover body to the heat insulation component. The bottom of the guide cover body is pressed against the top of the inner heat insulation plate, thereby forming an L-shaped channel to improve the sealing ability of the connection.

[0016] The top of the flow guide cover is snapped into and fixed to the upper cover, thereby limiting and fixing the heat insulation component through the cooperation of the housing and the upper cover.

[0017] Preferably, the guide cover body is provided with a guide cover body through hole, the upper cover is provided with an upper cover through hole, and the two ends of the guide tube are respectively connected to the guide cover body through hole and the upper cover through hole. Hot steam first passes through the guide cover body through hole, then passes through the guide tube, and finally leaves from the upper cover through hole.

[0018] Preferably, the upper cover includes an upper cover body and a central connecting cover. The upper cover body is fixedly connected to the flow guide cover body by a snap-fit ​​method, and the central connecting cover is snap-fitted to the upper cover body by a snap-fit ​​method, thereby fixing the heat insulation component to the upper cover and covering the connection part between the heat insulation component and the upper cover body by the central connecting cover.

[0019] Preferably, the guide cap body is made of silicone, and the guide tube is a retractable flexible tube.

[0020] Preferably, a handle is provided on the outside of the housing, which makes it easier to move the air humidifier.

[0021] Preferably, the device further includes a control circuit board and a knob. The knob is disposed inside the working cavity and on the housing. The control circuit board is electrically connected to both the knob and the heating assembly. The knob controls the working state of the heating assembly through the control circuit board.

[0022] The beneficial effects of the air humidifier of the present invention are as follows:

[0023] By installing a heat insulation unit to separate the inner and outer heating chambers, the water temperature in the outer heating chamber remains relatively low during humidification operation. Furthermore, a flow guide cap seals off the water in the inner heating chamber, ensuring that even if the humidifier tips over, the hot water in the inner heating chamber can only flow out slowly through the flow guide pipe, thus reducing the risk of injury should the humidifier tip over.

[0024] By setting up a heat insulation unit to separate the inner heating chamber and the outer heating chamber, the rate of water temperature transfer between the inner and outer heating chambers can be reduced, thereby improving the heating efficiency of the air humidifier.

[0025] By setting up inner and outer heat insulation panels and forming a heat insulation groove between them, the heat insulation capacity of the heat insulation component can be greatly improved. Attached Figure Description

[0032] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0034] Reference Figures 1 to 5 An embodiment of the air humidifier of the present invention is presented:

[0035] An air humidifier includes a housing 1, a top cover 2, a knob 6, a handle 7, a control circuit board 5, a heat insulation component 3, and a heating component 4.

[0036] The housing 1 is divided into a bottom working chamber and a top heating chamber. The control circuit board 5 and heating assembly 4 are located within the working chamber. A knob 6 is located outside the working chamber and connected to the housing 1. The knob 6 and heating assembly 4 are electrically connected to the control circuit board 5. A heat insulation assembly 3 is located inside the heating chamber. The bottom of the inner heating chamber on the inner side of the housing 1 is recessed towards the working chamber, forming an inner connecting groove. The heating assembly 4 is located inside the working chamber at the corresponding inner connecting groove. A handle 7 is located on the outside of the housing 1.

[0037] The upper cover 2 includes an upper cover body 21 and a central connecting cover 22, which is snapped onto the upper cover body 21. The upper cover body 21 is provided with an upper cover through hole.

[0038] The heat insulation component 3 includes a heat insulation component body 31 and a flow guide cover. The flow guide cover is disposed on the heat insulation component body 31, and the heat insulation component body 31 divides the heating chamber into an inner heating chamber and an outer heating chamber.

[0039] References in this patent Figure 3 , Figure 4 and Figure 5 Two embodiments of the thermal insulation component body 31 are given below.

[0040] Reference Figure 3 and Figure 4 The heat insulation component body 31 includes an inner heat insulation plate 312 and an outer heat insulation plate 311.

[0041] The inner heat insulation plate 312 and the outer heat insulation plate 311 are connected at their bottoms, forming a heat insulation groove 315 between them. The heat insulation groove 315 improves the heat insulation capacity of the heat insulation component 3. The tops of the inner heat insulation plate 312 and the outer heat insulation plate 311 are bent inward to form an inner heat insulation plate connecting flange and an outer heat insulation plate connecting flange. By setting the inner heat insulation plate connecting flange and the outer heat insulation plate connecting flange, external debris or moisture can be prevented from entering the heat insulation groove 315.

[0042] The bottom of the inner heat insulation plate 312 extends towards the bottom to form an annular inner heat insulation plate retaining block 313, which is snapped into the connecting groove inside the housing. This secures the heat insulation component 3 inside the housing 1. The inner heat insulation plate retaining block 313 has a heat insulation component body through hole 314, and the inner heat insulation plate retaining block 313 is higher than the connecting groove inside the housing, allowing water to smoothly enter the inner heating chamber.

[0043] Reference Figure 5 The heat insulation component body 31 includes an inner heat insulation plate 312 and an outer heat insulation plate 311.

[0044] The inner heat insulation plate 312 and the outer heat insulation plate 311 are connected at the bottom and form a heat insulation groove 315 between them. The inner heat insulation plate 312 and the outer heat insulation plate 311 are also connected at the top. A heat insulation cavity is formed in the heat insulation groove 315 between the inner heat insulation plate 312 and the outer heat insulation plate 311. The heat insulation effect is improved by vacuuming inside the heat insulation cavity.

[0045] The bottom of the inner heat insulation plate 312 extends towards the bottom to form an annular inner heat insulation plate retaining block 313, which is snapped into the connecting groove inside the housing. This secures the heat insulation component 3 within the housing 1. The inner heat insulation plate retaining block 313 has a through hole 3114 for the heat insulation component body, and the inner heat insulation plate retaining block 313 is higher than the connecting groove inside the housing, allowing water to smoothly enter the inner heating chamber.

[0046] The flow guide cover includes a flow guide cover body 32 and a flow guide tube 33. A lower locking block is provided at the bottom of the flow guide cover body 32. This lower locking block is inserted into the inner side of the inner heat insulation plate 312 and engages with it, thereby engaging the flow guide cover body 32 with the heat insulation component 3. The bottom of the flow guide cover body 32 is pressed against the top of the inner heat insulation plate 312, forming an L-shaped channel to improve the sealing ability at the connection. The flow guide cover body 32 is connected to the upper cover body 21 via a locking mechanism, thus securing the flow guide cover body 32 to the upper cover 2. The upper cover 2 limits the flow guide cover on the upper side, and the connecting groove inside the housing limits and fixes the heat insulation component body 31 on the lower side, thereby securing the entire heat insulation component 3 within the housing 1. A through hole is provided on the flow guide cover body 32. Both ends of the flow guide tube 33 are connected to the through hole of the flow guide cover body and the through hole of the upper cover, respectively.

[0047] During use, the water in the inner heating chamber is heated by the heating component 4. This heats the water, generating steam that flows sequentially through the through-hole of the guide cover, then through the guide pipe 33, and finally exits through the through-hole of the top cover. During operation, water from the outer heating chamber enters the inner heating chamber through the through-hole 314 of the insulation component to replenish it. By incorporating the insulation component 3, the heating rate of the water in the inner heating chamber is increased, and the temperature of the water in the outer heating chamber during air humidification is reduced, thus preventing injury to personnel should the humidifier tip over.

[0048] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
