[0002] With the improvement of people's living standards and the increasing requirements for indoor air quality, humidifiers, as electrical devices for regulating indoor humidity, are widely used in various scenarios such as homes, offices, and industrial workshops.

[0003] Humidifiers typically contain a control circuit board and multiple electrical components. To control these components, each component needs to be electrically connected to the control circuit board. This necessitates multiple communication interfaces for the control circuit board. Since the number of electrical components varies between different humidifier models, and even different versions of the same model, different control circuit boards are required for different models and even different versions of humidifiers, increasing production costs. However, equipping all humidifiers with the same control circuit board would inevitably lead to redundant and wasteful communication interfaces in humidifiers with fewer electrical components.

[0004] The purpose of this invention is to solve the problem of the large number of communication interfaces on the control circuit board of existing humidifiers.

[0005] To achieve the above objectives, this utility model provides a humidifier, comprising:

[0008] An expansion board is disposed inside the housing and electrically connected to the control circuit board via a communication line. The expansion board is configured with multiple communication interfaces, each of which is used to connect to different electrical components of the humidifier, so that the control circuit board can control each of the electrical components that are communicatively connected to the expansion board through the expansion board, and collect electrical signals of at least one of the electrical components that are communicatively connected to the expansion board through the expansion board.

[0010] Optionally, the air inlet is disposed on the circumferential wall of the housing, and the air outlet is formed on the top wall of the housing; the water absorption and evaporation component is configured as a cylinder.

[0019] Because the control circuit board controls the various electrical components, while the expansion board transmits electrical signals, the expansion board has fewer electronic components than the control circuit board, and its cost is also lower.

[0043] Continue reading Figure 1 In some embodiments of this utility model, the air inlet 101 is disposed on the circumferential wall of the housing 100, and the air outlet 102 is formed on the top wall of the housing 100.

[0044] The air inlet 101 consists of multiple through holes evenly distributed on the circumferential wall of the housing 100. The air outlet 102 consists of multiple through holes formed on the top wall of the housing 100.

[0045] In other embodiments of this utility model, those skilled in the art can also interchange the positions of the air inlet 101 and the air outlet 102 as needed.

[0046] like Figure 1 As shown, in some embodiments of this utility model, the water absorption and evaporation component 200 is disposed between the air inlet 101 and the air outlet 102 in the air flow path, so that the flowing air can flow through the water absorption and evaporation component 200.

[0047] The water-absorbing and evaporating component 200 can be made of any feasible material such as cloth, porous ceramics, or porous metal.

[0048] Continue reading Figure 1 In some embodiments of this utility model, the water-absorbing evaporation component 200 can be configured as a cylindrical shape to fit the circumferential wall of the shell 100.

[0049] like Figure 1 As shown, in some embodiments of this utility model, the electrical component 400 includes a water pump 401 and a fan 402. The water pump 401 is used to transport water from the water tank 300 to the water absorption and evaporation component 200.

[0050] The fan 402 includes a motor (not marked in the figure) and fan blades or impellers (not marked in the figure) that are driven and connected to the fan 402.

[0051] Continue reading Figure 1 In some embodiments of this utility model, the electrical component 400 may further include at least one of a water level sensor 403, an ultraviolet lamp 404, and a temperature and humidity sensor 405.

[0052] The water level sensor 403 is used to detect the water level in the water tank 300, and the water level sensor 403 can be installed on the water tank 300.

[0053] The ultraviolet lamp 404 is used for sterilization. The ultraviolet lamp 404 can be installed inside the water absorption and evaporation component 200 to sterilize and disinfect the water absorption and evaporation component 200.

[0054] The temperature and humidity sensor 405 is used to detect the temperature and humidity in the environment and can be installed on the housing 100.

[0055] like Figure 1 As shown, the water receiving tank 500 and the water storage tank 600 are respectively provided on the top and bottom sides of the water absorption and evaporation component 200, so that the water absorption and evaporation component 200 can be clamped and fixed by the water receiving tank 500 and the water storage tank 600.

[0056] Alternatively, those skilled in the art can fix the water-absorbing evaporation component 200 to the housing 100 using any other feasible fixing method as needed. For example, it can be directly fixed to the housing 100 by means of clips, screws, etc. As another example, a support frame can be provided for the water-absorbing evaporation component 200, and the support frame can be fixedly connected to the housing 100, and then the water-absorbing evaporation component 200 can be fixedly connected to the support frame.

[0057] Continue reading Figure 1 In some embodiments of this utility model, the water receiving tank 500 is annular, and the bottom wall of the water receiving tank 500 is provided with water spraying holes 501 aligned with the water absorption and evaporation component 200. The water pump 401 pumps water (such as...) from the water tank 300 through a pipeline (not shown in the figure). Figure 1 (As indicated by the middle arrow) The water is transported to the water receiving tank 500, and the water in the water receiving tank 500 is sprayed onto the water absorption and evaporation component 200 through the water spraying hole 501 under the action of gravity.

[0058] Continue reading Figure 1 In some embodiments of this utility model, the water storage tank 600 is used to collect water flowing down from the water absorption and evaporation member 200. Furthermore, the bottom wall of the water storage tank 600 is provided with a drain hole 601.

[0059] from Figure 1As can be seen, the water tank 300 is located on the bottom side of the drain hole 601. The drain hole 601 is connected to the water tank 300 through the drain pipe 610 so that water in the water storage tank 600 can be introduced into the water tank 300 through the drain pipe 610.

[0060] Continue reading Figure 1 In some embodiments of this utility model, a water inlet 103 is provided on the top side of the housing 100, and a water inlet pipe 700 is provided inside the housing 100 to connect the water inlet 103 to the water tank 300, so that the user can add water to the water tank 300 from the top side of the humidifier 001.

[0061] The following reference Figure 1 The working principle of the humidifier 001 in some embodiments of this utility model will be briefly explained below.

[0062] First, the user adds water to the water tank 300 through the water inlet 103.

[0063] Then, the humidifier 001 is turned on, and the water pump 401 of the humidifier 001 delivers water to the water receiving tank 500. Under the action of gravity, the water in the water receiving tank 500 is sprayed onto the water absorption and evaporation component 200 through the water spray holes 501. The rotating fan 402 drives the outside air to flow sequentially through the air inlet 101, the water absorption and evaporation component 200 and the air outlet 102, thereby causing the water on the water absorption and evaporation component 200 to evaporate and form water vapor, thus humidifying the air.

[0064] During this process, water that cannot evaporate on the water absorption and evaporation component 200 will flow into the water storage tank 600. The water in the water storage tank 600 will then re-enter the water tank 300 through the drain pipe 610 to conserve water resources and prevent leakage.

[0065] like Figure 2 As shown, in some embodiments of this utility model, the expansion board 900 is electrically connected to the control circuit board 800 via a communication line (not marked in the figure), so that the expansion board 900 and the control circuit board 800 can be arranged separately in space, making the arrangement more flexible.

[0066] Continue reading Figure 2 In some embodiments of this utility model, the expansion board 900 is equipped with multiple communication interfaces 910, each communication interface 910 being used to connect different electrical components 400 of the humidifier 001, so that the control circuit board 800 controls each electrical component 400 that is communicatively connected to the expansion board 900 through the expansion board 900, and collects electrical signals of at least one electrical component 400 that is communicatively connected to the expansion board 900 through the expansion board 900.

[0067] The number of communication interfaces 910 on the expansion board 900 can be any feasible number, such as 1, 2, 5, 8, 10, 12, 15, or 20.

[0068] Those skilled in the art will understand that by providing an expansion board 900 electrically connected to the control circuit board 800, and by providing multiple communication interfaces 910 on the expansion board 900, the control circuit board 800 can connect to different electrical components 400 of the humidifier 001 through the expansion board 900, greatly reducing the number of communication interfaces 910 on the control circuit board 800. At the same time, the expansion board 900 with multiple communication interfaces 910 also increases the functional expandability of the humidifier 001. That is, corresponding functional modules can be connected to the communication interfaces 910 according to the functions that the humidifier 001 needs to be configured with.

[0069] Since the control circuit board 800 controls the various electrical components 400, and the expansion board 900 transmits electrical signals, the expansion board 900 has fewer electronic components than the control circuit board 800, and its cost is also lower. This results in a lower overall cost for the humidifier 001.

[0070] Furthermore, since the expansion board 900 is electrically connected to the control circuit board 800 via a communication cable, there are fewer wires around the control circuit board 800, making wiring simpler.

[0071] Furthermore, although not shown in the figure, in some embodiments of this utility model, the extension plate 900 can be fixedly connected to the water pump 401, fixedly connected to the housing 100, or fixedly connected to any other component.

[0072] Continue reading Figure 2 In some embodiments of this utility model, at least one of the plurality of communication interfaces 910 is used for communication connection to a fan 402, at least one of the plurality of communication interfaces 910 is used for communication connection to a water pump 401, at least one of the plurality of communication interfaces 910 is used for communication connection to a water level sensor 403, at least one of the plurality of communication interfaces 910 is used for communication connection to an ultraviolet lamp 404, and at least one of the plurality of communication interfaces 910 is used for communication connection to a temperature and humidity sensor 405.

[0073] In other words, the expansion board 900 provides corresponding communication interfaces 910 for different electrical components 400. Furthermore, those skilled in the art can make the communication interfaces 910 for different electrical components 400 different as needed. Alternatively, the communication interfaces 910 for different electrical components 400 can be the same to simplify the assembly of the humidifier 001.

[0074] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0075] Finally, it should be noted that in this invention, the term "connection" refers to fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage between two interconnected entities.
