Description

This application relates to the field of humidification devices, and in particular to humidifiers.

Currently, a humidifier is a device for adjusting the humidity of air. Conventional evaporative humidifiers usually increase the environmental humidity by wetting a filter with water and then blowing the air that has passed through the filter into the room using a fan. There are two main types of water filling methods for general humidifiers: one in which water is directly poured into the water storage container inside the humidifier, and one in which water is directly poured into the water inlet at the top of the humidifier. The first type of water filling method is relatively cumbersome and requires repeated attachment and detachment of the device, which is not quick. The second type of water filling method is relatively easy to operate and is becoming a new trend in humidifiers. However, with commercially available humidifiers that use the top water filling method, when water is added, the water splashes out due to the wind blowing out.

The purpose of this application is to provide a humidifier that solves to some extent the technical problem present in the prior art, that is, water is easily scattered around due to the wind blown out when water is added by a top-addition humidifier.

The humidifier according to the embodiment of the present application will be described below with reference to Figures 1 to 11.

As shown in Figures 1 to 11, an embodiment of the present application provides a humidifier, which includes a water storage container 3 and a main body member consisting of a first casing 1 and a second casing 2. The main body member is formed with a water injection passage and an air guide passage that have different paths and are independent of each other and do not interfere with each other. Specifically, the second casing 2 is fitted to the outside of the first casing 1 and the two are fixed to each other, the height of the first casing 1 is lower than that of the second casing 2, and the water storage container 3 is located at the bottom of the first casing 1. A water injection component 8 is installed at the upper end opening of the second casing 2, and the water injection component 8 is connected to the water storage container 3 by a water injection passage, thereby realizing the water injection method of the present humidifier by adding water from above. Inside the second casing 2, an air guide passage is formed inside the main body member, and the air guide passage is isolated from both the water injection passage and the water injection chamber 100 and does not affect each other. As can be seen, the humidifier provided in this embodiment uses two mutually independent passages to blow air and add water, effectively preventing the water from being splashed around due to the wind from the air guide affecting the water being added when adding water.

Specifically, the main body member further has a bottom cap, the bottom of the first casing 1 extends outward to form a fixing edge 101, the bottom cap is provided below the first casing 1, the first casing 1 may have a relatively tall cylindrical structure, the bottom of the first casing 1 is close to the bottom of the second casing 2, when the second casing 2 is fitted to the outside of the first casing 1, the bottom end of the second casing 2 is fixed to the fixing edge 101 of the first casing 1, the fixing method between the second casing 2 and the first casing 1 can be a locking connection, but is of course not limited thereto.

The first casing 1 is fitted to the outside of the water storage container 3; in other words, the water storage container 3 is installed inside the first casing 1, a water supply channel is installed inside the water storage container 3, a filter 4 is installed at the upper opening of the water storage container 3, a first locking connection part is installed on the inner wall surface of the upper opening of the water storage container 3, the shape of the filter 4 matches the opening shape of the water storage container 3, and a second locking connection part that matches the first locking connection part and can be locked and connected is installed on the outer surface of the filter 4, which not only allows the filter 4 to be fixed to the water storage container 3, but also allows the filter 4 to be installed floating above the liquid surface in the water storage container 3, preventing the filter 4 from coming into direct contact with the water in the water storage container 3, effectively solving the problem of the filter 4 being immersed in water for a long period of time and prone to bacterial growth.

Alternatively, the first casing 1 may have a relatively low annular structure. In such a case, the first casing 1 is disposed coaxially with the second casing 2 within the second casing 2, and the first casing 1 is located in the middle section of the second casing 2. In this case, the water storage container 3 is disposed below the first casing 1, and preferably the first casing 1 is fixed to the upper end opening of the water storage container 3.
In the present application, an embodiment in which the first casing 1 has a cylindrical structure is preferred.

At the bottom of the water storage container 3, a pump 5, preferably a DC brushless pump, is installed. The pump 5 provides pressure to the water in the water storage container 3, so that the water can be pumped through the water supply passage to the filter 4 in small amounts multiple times. The filter 4 has a water absorption capacity and can absorb moisture sufficiently to keep it moist. Preferably, a nozzle is installed at one end of the water supply passage away from the pump 5, and the end of the water supply passage and the nozzle extend to above the filter 4. After the pump 5 draws the water to above the filter 4, the water is sprayed through the nozzle onto the filter 4 in a manner similar to spraying from a shower head, moistening the filter 4, so that the filter 4 is filled with water and has a uniform degree of moisture, and the air passes through the moistened filter 4 and is carried away by the wind, thereby achieving a humidifying effect.

Preferably, the filter 4 has a ring-shaped structure, and supports capable of supporting the filter 4 are installed on both the inner and outer edge wall surfaces of the filter 4, the inner edge of the ring-shaped structure forms a perforated portion, and the filter 4 is installed inside the end opening of the water storage container 3, in other words, the outer diameter of the filter 4 is smaller than the inner diameter of the water storage container 3, and the water sprayed from the nozzle onto the filter 4 can flow down along the inner wall of the water storage container 3 as it falls, and the water that returns to the bottom rejoins the circulation, and almost no noise is generated during the process of returning to the bottom.
More preferably, as shown in FIG. 11 , the diameter of filter 4 gradually increases from top to bottom, so that an included angle α is formed between the outer surface of filter 4 and the vertical plane, the magnitude of α being 3° to 10°, and preferably 5°, and because filter 4 has a ring-shaped structure, the part of filter 4 that performs the water-absorbing function also has a ring-shaped structure, and in this embodiment, filter 4 has a structure that is narrow at the top and wide at the bottom, and the cross-sectional area is relatively large, so that the water absorption is effectively improved, and when air passes through filter 4, the contact area between the air and filter 4 is also relatively large, thereby effectively improving the humidifying effect of this humidifier.

Furthermore, since the height of the first casing 1 is lower than that of the second casing 2, an air guide component 6 is installed inside the main body member. Preferably, the air guide component 6 is installed above the first casing 1, or the air guide component 6 has an integral structure with the first casing 1 so that the two are fused together. The air guide component 6 includes a first air guide member 601 and a second air guide member 602, the first air guide member 601 has an annular structure, the second air guide member 602 has a bowl-shaped structure, and both the upper and lower ends of the second air guide member 602 are open. The diameter of the upper end opening of the second air guide member 602 is approximately the same as the diameter of the lower end opening of the first air guide member 601, so that the first air guide member 601 and the second air guide member 602 can engage with each other, and the opening at the bottom end of the second air guide member 602 has a relatively small diameter. When the first air guide member 601 and the second air guide member 602 are engaged with each other, the space enclosed by the first air guide member 601 and the second air guide member 602 forms an installation space.
Furthermore, a plurality of water guide channels 6021 are arranged on the side wall of the second air guide member 602 at intervals in the circumferential direction of the second air guide member 602. The water guide channels 6021 extend vertically and each water guide channel 6021 is arranged through the second air guide member 602. The upper ends of the water guide channels 6021 protrude beyond the inner wall surface of the second air guide member 602 and the lower ends of the water guide channels 6021 protrude beyond the outer wall surface of the second air guide member 602. Preferably, the water guide channels 6021 and the second air guide member 602 have an integral structure and are processed by an integral injection molding method.

Furthermore, the humidifier provided by the embodiment of the present application includes a flow-guiding component 7, and specifically, the flow-guiding component 7 includes a motor cover 701, a motor cover cap 702, a motor 703, and a fan 704. The motor cover cap 702 is provided to be engaged with the motor cover 701 to form a fixed chamber 300, a motor 703 is installed in the fixed chamber 300, a drive shaft is installed on the motor 703, one end of the drive shaft penetrates the motor cover 701 and extends to the outside of the motor cover 701, and a fan 704 is connected to the drive shaft, so that the fan 704 can be operated by driving the motor 703. The motor cover 701 and the motor cover cap 702 can position and fix the motor 703, and ensure the stability of the motor 703 and the fan 704 connected to the motor 703, so that when the motor 703 is started, the operation of the fan 704 is driven and wind is generated.

The fan 704 is located above the filter 4 and is installed near the filter 4, a first ventilation passage 400 is formed in the portion between the outer wall surface of the fixed chamber 300 and the inner wall surface of the mounting space, a second ventilation passage 500 is formed in the gap between the first casing 1 and the second casing 2, the fixed edge portion 101 at the bottom of the first casing 1 has a grid structure, and the grid structure serves as an air intake port, and the upper end of the first ventilation passage 400 is an exhaust port, preferably an annular port, and the exhaust port is installed to surround the water injection component 8. As shown in Figures 1, 2 and 6, the second ventilation passage 500, filter 4, fan 704 and first ventilation passage 400 are connected in this order from bottom to top, and together form an air guide passage. When the fan 704 starts to operate, a unidirectional airflow is formed inside the main body member. The unidirectional airflow flows from bottom to top, passing through the second ventilation passage 500, the water-containing filter 4, the blades of the fan 704, and the first ventilation passage 400 in this order, and then flows out from the outlet of the first ventilation passage 400, which sends the moisture in the filter 4 into the air outside the main body member, thereby achieving a humidifying effect.

In addition, when the first casing 1 has a ring-shaped structure, the space between the outer wall surface of the water storage container 3 and the second casing 2 and the space between the outer wall surface of the first casing 1 and the second casing 2 jointly form the second ventilation passage 500.
Preferably, a sealing member is installed at the connecting position where the motor cover 701 and the motor cover cap 702 engage with each other to prevent water from entering the fixed chamber 300 during water injection and affecting the normal operation of the motor 703 .

Furthermore, a plurality of water flow paths 7021 are provided at intervals on the outer wall surface of the side wall of the motor cover cap 702 in the circumferential direction of the motor cover cap 702. Preferably, the number of water flow paths 7021 is the same as the number of water conduits 6021, and each of them is preferably three. The three water flow paths 7021 communicate with the three water conduits 6021 in a one-to-one correspondence. Each water flow path 7021 has a drain port, and the drain port is located near the bottom surface of the side wall of the motor cover cap 702. Preferably, the length, i.e., the height, of the water flow paths 7021 extends downward, and the lower end of the water flow path 7021 is preferably 1/2. extends downward on the outer wall surface of the motor cover cap 702 to the upper end of the water guideway 6021 of the second air guide member 602, and the water flow path 7021 is hermetically connected to the water guideway 6021, so that the water flowing down from the water inlet 803 flows through the multiple water flow paths 7021 into the multiple water guideways 6021 respectively, and does not enter other parts inside the second air guide member 602, that is, the water does not enter the installation space, so that the gas and water flow in a part of the space inside the main body member are separated into two paths, and mutual influence is avoided. As can be seen from this, the flow guide component 7 not only plays the role of fixing the motor 703 and the fan 704, but also plays the role of guiding the water flow during the water addition process.
Preferably, a channel cover plate 7022 is installed at the upper end of the water channel 7021, and the channel cover plate 7022 and the upper end opening of the water channel 7021 are engaged with each other or fixed by welding to prevent water from splashing out of the water channel 7021 when water is added.

Furthermore, the water injection component 8 is installed at the upper end opening of the mounting space and located above the motor cover cap 702, specifically, the water injection component 8 includes at least one fixing member, preferably, in this embodiment, the number of fixing members is two, the two fixing members are respectively a first fixing member 801 and a second fixing member 802, the first fixing member 801 and the second fixing member 802 are mutually engageable, the first fixing member 801 and the second fixing member 802 both have a ring structure, and when the first fixing member 801 and the second fixing member 802 are mutually engaged, the circular opening of the first fixing member 801 becomes the water injection port 803. The motor cover cap 702 has a tank structure, and the shape of the second fixing member 802 matches the shape of the motor cover cap 702, so the second fixing member 802 can be placed in the tank structure of the motor cover cap 702, and the second fixing member 802 is fixed to the motor cover cap 702. The space enclosed by the first fixing member 801, the second fixing member 802, and the motor cover cap 702 is the water injection chamber 100. When water is added through the water injection port 803, the water enters the water injection chamber 100, that is, it is located within the tank structure of the motor cover cap 702.

In addition, the humidifier provided in the embodiment of the present application also includes a water-guiding component 9, which includes a sealing ring 902 and a water-guiding ring 901 having a ring-shaped structure. The water-guiding ring 901 is connected to the filter 4, and the lower end opening of the second air-guiding member 602 is located at the inner edge of the water-guiding ring 901, thereby ensuring communication between the internal space of the second air-guiding member 602, i.e., the first ventilation passage 400, and the filter 4. The space between the second air guide member 602 forms the water guide chamber 200. Water flowing down from the water guide channel 6021 enters the water guide chamber 200. The water flows through the water inlet chamber 100 and the water guide chamber 200 in that order, guided by the water guide ring 901, to the perforated section, then flows down along the inner wall surface of the perforated section, and finally flows into the water storage container 3. During the water injection process, the route along which the water flows is the water inlet chamber 100, the water guide chamber 200, the perforated section of the filter 4, and the water storage container 3, which is the water injection channel. As can be seen from this, the water flows into the water storage container 3 via the inner wall surface of the ring structure of the filter 4, and there is no interference with the wind flowing through the mesh part of the filter 4.

Furthermore, an attachment portion is provided at the upper end opening of the first casing 1, and a sealing ring 902 is installed at the attachment portion and positioned between the water guide ring 901 and the first casing 1, and is used to seal the gap between the water guide ring 901 and the first casing 1 to prevent water leakage from the gap between the two.

Specifically, the upper end opening of the first casing 1 is narrowed inward to form an attachment part, the cross section of the sealing ring 902 is U-shaped, and the U-shape opens downward, and the sealing ring 902 is installed in close contact with the inner wall of the first casing 1. The water guide ring 901 includes a fixed part 9011 having an integral structure, a first water guide part 9012, and a second water guide part 9013, the fixed part 9011 extends above the first water guide part 9012 and is engaged and installed within the sealing ring 902, the first water guide part 9012 has a ring structure, the outer edge of the first water guide part 9012 is connected to the fixed part 9011, the inner edge of the first water guide part 9012 is connected to the second water guide part 9013, the second water guide part 9013 also has a ring structure, and the axial direction of the second water guide part 9013 is distributed vertically, and preferably, the second water guide part 9013 is connected to the fixed part 9011. The lower end of the section 9013 extends until it abuts against the inner wall surface of the filter 4, and more preferably, the outer edge of the first water guide section 9012 is placed higher than the inner edge, so that the first water guide section 9012 is installed at an angle to act as a guide, and the lower end opening of the water guide channel 6021 is installed directly opposite the first water guide section 9012, so that water flowing out of the water guide channel 6021 falls into the first water guide section 9012, and then flows along the first water guide section 9012, the surface of the second water guide section 9013, and the inner wall surface of the filter 4 into the water storage container 3.

Furthermore, the upper end of the filter 4 has a support, a first insertion portion is formed on the support, and a second insertion portion that can be fitted and connected to the first insertion portion is installed on the water guide ring 901, ensuring stability between the water guide ring 901 and the filter 4, while having a mutually interlocking rib structure between the two. The method of interlocking prevents air (wind) that has not passed through the wet filter 4 from flowing into the first ventilation passage 400, which affects the effect and efficiency of humidification.

In summary, the humidifier provided by the present application has an independent water injection channel defined by the installation of a water injection component, allowing the humidifier to normally blow air while water is being injected, and the water injection channel and the air outlet path do not affect each other, ensuring that air continues to blow smoothly while water is being injected and that water droplets do not splash. This significantly improves convenience during water injection and also prevents surrounding objects from getting wet due to splashing water droplets.

In addition, in the humidifier provided in the embodiment of the present application, the water flow falls along the inner wall surface of the filter without coming into contact with the fan during the water injection process, which prevents the annoying collision noise caused by the water coming into contact with the fan blades when water is added, and also prevents the water from falling directly from a high position into the water storage container, which creates a loud noise.

Finally, it should be noted that the above embodiments are merely for the purpose of explaining the technical solutions of the present application, and are not intended to limit the same. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can understand that the technical solutions described in the above embodiments may be modified or equivalently substituted for part or all of the technical features, but such modifications or substitutions do not cause the essence of each technical solution to deviate from the scope of the technical solutions of each embodiment of the present application.
