The air flow driving assembly is configured to drive the atomizing air flow and the humidifying air flow to be discharged from the air flow channel.

[0011] The humidifying device of the present utility model is provided with an atomizing device and a humidifying device. The humidifying device is detachably arranged in the water storage cavity. When atomizing humidification is required, the humidifying device is detached from the water storage cavity, and the atomizing device and the air flow driving component are started. When evaporation humidification is required, the humidifying device is installed in the water storage cavity, and the humidifying device, the air flow driving component are started and the atomizing device is turned off. The present utility model integrates the atomizing device and the humidifying device in a device main body, enabling a humidifying device to switch between two humidifying methods, namely atomizing humidification and evaporation humidification, so that the humidifying device can not only be applicable to different application scenarios, but also reduce the required installation space.

[0017] An installation position for placing the humidifying filter element is provided in the water storage cavity. When the humidifying filter element is arranged at the installation position, the trigger triggers the switch to turn off the power supply line. When the humidifying filter element is separated from the installation position, the trigger triggers the switch to turn on the power supply line.

[0018] In this way, by setting the trigger, the switch and the power supply line, the opening and closing of the atomizing device can be controlled according to whether the humidifying device is installed in the water storage cavity, which is convenient for controlling the switching of the humidifying device between the atomizing humidification mode and the evaporation humidification mode.

[0026] In this way, by providing the magnetic member and the Hall switch, the opening and closing of the switch member are controlled by using the trigger member.

[0027] In some embodiments, a counterbore recessed away from the water tank is formed in the bottom wall of the atomization cavity, and the counterbore and the atomization channel are arranged opposite to each other along the height direction of the humidifying device.

[0028] The atomization device is disposed in the counterbore.

[0029] In this way, by providing the counterbore and installing the atomization device in the counterbore, it is convenient for the water entering the device main body from the water tank to contact the atomization device, so that the atomization device atomizes the water.

[0030] In some embodiments, the atomization device includes an ultrasonic atomizer.

[0031] In some embodiments, the air flow driving assembly includes a first fan, and the first fan is disposed in the device main body to drive the atomized air flow in the atomization cavity to be discharged from the atomization channel to the air flow channel.

[0032] In this way, by providing the first fan, it is convenient for the atomized gas in the atomization cavity to enter the air flow channel, and the flow rate of the atomized gas in the atomization cavity is increased.

[0033] In some embodiments, a partition is provided on the inner side of the device main body.

The atomization cavity is located on the side of the device cavity close to the water tank, and the atomization cavity and the device cavity are communicated;

[0034] The first fan is disposed in the device cavity.

[0035] In this way, by providing the partition, the device main body is divided into an atomization cavity and a device cavity respectively, and the first fan is disposed in the device cavity, so that the first fan is isolated from the atomized gas in the atomization cavity, and damage to the first fan caused by the atomized gas is avoided as much as possible.

The rod portion is movably disposed through the drain opening along the axial direction of the drain opening, and the plugging portion is disposed at one end of the rod portion. The plugging portion is configured to plug the drain opening;

[0040] A driving device, which is in transmission cooperation with the rod portion to drive the rod portion to move.

[0041] Thus, by providing the valve stem and the driving device, it is convenient to control the opening and closing of the drain opening, thereby controlling the start and stop of the water supply from the water tank to the atomization chamber.

The first end is in abutting cooperation with the valve stem, the second end is connected to the floating portion, and the portion of the connecting portion between the first end and the second end is pivotally connected to the float bracket.

[0045] Thus, by providing the float bracket and the float body, when there is water in the atomization chamber and the water can drive the floating portion to move upward, the floating portion drives the connecting portion to rotate relative to the float bracket. The first end of the connecting portion contacts the valve stem during the movement and can drive the valve stem to move, thereby realizing the opening and closing of the drain opening.

[0046] In some embodiments, the switch assembly further includes:

[0047] An elastic reset member sleeved on the rod portion. One end of the elastic reset member abuts against the bottom wall of the water tank, and the other end abuts against the plugging portion.

[0048] Thus, by providing the elastic reset member, when the elastic reset member is in a natural state, the plugging portion closes the drain opening. When it is necessary to open the drain opening, the driving device overcomes the force of the deformation of the elastic reset member and pushes the rod portion to move, so that the plugging portion opens the drain opening, improving the stability of the switch assembly in plugging the drain opening.

[0054] In this way, by providing the housing main body, the mounting bracket, and the second fan, it is convenient to install and fix the second fan, so as to facilitate transporting the humidified air to the outside through the air flow channel. Moreover, when the atomizing device is started, the atomizing gas can be double-accelerated under the action of the first fan and the second fan, dispersing the fog density of the atomizing gas and increasing the fog height of the atomized air, thereby effectively avoiding the phenomenon of water stains near the device body.

[0055] In some embodiments, the mounting bracket is arranged at one end of the housing main body facing the water tank. The mounting bracket includes:

[0056] A mounting main body and a plurality of connecting ribs. The mounting main body is located in the middle of the air flow channel, and the plurality of connecting ribs are arranged at intervals along the circumference of the mounting main body. The mounting main body is connected to the housing main body through the connecting ribs.

[0057] In this way, by providing the mounting main body and the connecting ribs, it is convenient to install the mounting bracket in the housing main body.

[0076] In order to make the above - mentioned objects, features and advantages of the embodiments of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0077] Humidifying equipment such as a humidifier is an electrical appliance that can increase humidity. There are mainly two types of humidifiers. One is an atomizing humidifier, and the other is an evaporative humidifier. The atomizing humidifier is generally an ultrasonic humidifier. The ultrasonic humidifier has a good humidifying effect on a local space, is energy - saving and environmentally friendly, but has a short transmission distance. The evaporative humidifier has a large humidifying space, but has a high noise level and high energy consumption.

[0078] In the same application place, when the above two types of humidifiers are needed, only one atomizing humidifier and one evaporative humidifier can be placed separately, which requires a large amount of space.

[0079] In view of this, the present utility model provides a humidifying equipment that can switch between two humidifying methods, namely atomizing humidification and evaporative humidification, so that the humidifying equipment can not only be applicable to different application scenarios, but also reduce the required installation space.

[0080] The following will specifically describe the technical solutions of the present utility model and how the technical solutions of the present utility model solve the above - mentioned technical problems in detail with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0081] Reference Figure 1, Figure 2 , Figure 3 and Figure 4 , embodiments of the present utility model disclose a humidifying device, which can be a household humidifier or an industrial humidifier. The humidifying device may include a device main body 100, a water tank 200, an atomizing device 300, a humidifying device 400, and an air duct assembly 500.

[0082] Among them, the device main body 100 may be in a cylindrical shape. The device main body 100 defines an atomizing chamber 110, the top of the atomizing chamber 110 is open, and the device main body 100 can provide a bottom support for the entire humidifying device.

[0083] The water tank 200 is provided on the device main body 100. The water tank 200 has a water storage chamber and a water outlet 210. The water outlet 210 can be opened and closed. The water storage chamber is communicated with the atomizing chamber 110 through the water outlet 210. When the water outlet 210 is opened, the water in the water storage chamber can pass through the water outlet 210, so as to supply water to the atomizing chamber 110. When the water outlet 210 is closed, the water storage chamber stops supplying water to the atomizing chamber 110.

[0084] The water tank 200 also defines an atomizing channel 220. The atomizing channel 220 communicates the atomizing chamber 110 with the water storage chamber. For example, a channel pipe may be provided inside the water storage chamber, and the inside of the channel pipe defines the atomizing channel 220. At this time, the water storage chamber can surround the atomizing channel. Optionally, the atomizing channel 220 may extend above the maximum allowable water level of the water storage chamber to prevent the atomizing air flow from contacting the water in the water tank 200 and being unable to be effectively discharged to the outside.

[0085] The atomizing device 300 is provided in the atomizing chamber 110 and is configured to atomize the water entering the atomizing chamber 110 to form an atomizing air flow. For example, the atomizing device 300 may be an ultrasonic atomizer.

[0086] The humidifying device 400 is detachably provided in the water storage chamber and is configured to evaporate the water adsorbed on the humidifying device 400 to form a humidifying air flow.

[0087] The air duct assembly 500 includes an air duct housing 510 and an air flow driving assembly 520. The air duct housing 510 defines an air flow channel communicated with the water storage chamber. In this way, the atomizing air flow generated in the atomizing chamber 110 enters the water storage chamber through the atomizing channel 220 and is finally discharged from the air flow channel. The air flow driving assembly 520 is configured to drive the atomizing air flow and the humidifying air flow to be discharged from the air flow channel.

[0088] Optionally, the device main body 100 may be a cylindrical housing. The top of the cylindrical housing has an opening. The water tank 200 is arranged above the cylindrical housing. The atomizing device 300 is arranged at the bottom of the atomizing chamber 110. The humidifying device 400 is detachably arranged in the water tank 200. The air duct assembly 500 is arranged above the water tank 200.

[0089] Optionally, the humidifying device further includes a control unit configured to control the opening and closing of the atomizing device 300, the humidifying device 400, and the air flow driving assembly 520. For example, when the humidifying device 400 is installed in the water storage cavity, the control unit controls the start of the humidifying device 400 and the air flow driving assembly 520 and the closing of the atomizing device 300 to achieve evaporative humidification; when the humidifying device 400 is detached from the water storage cavity, the control unit controls the start of the atomizing device 300 and the air flow driving assembly 520 to achieve atomizing humidification.

[0090] By adopting the above technical solution, by providing the atomizing device 300 and the humidifying device 400, the humidifying device 400 is detachably arranged in the water storage cavity. When atomizing humidification is required, the humidifying device 400 is detached from the water storage cavity, and the atomizing device 300 and the air flow driving assembly 520 are started. When evaporative humidification is required, the humidifying device 400 is installed in the water storage cavity, the humidifying device 400 and the air flow driving assembly 520 are started, and the atomizing device 300 is closed. The utility model integrates the atomizing device 300 and the humidifying device 400 in a device main body 100, enabling the humidifying device to switch between two humidifying modes of atomizing humidification and evaporative humidification, so that the humidifying device can not only be applicable to different application scenarios, but also reduce the required installation space.

[0091] In some embodiments, referring to Figure 2 and Figure 6 , the humidifying device 400 includes a humidifying filter element 410. For example, the humidifying filter element 410 can be in the shape of a cylinder with both ends open, and the humidifying filter element 410 can be sleeved on the radial outside of the atomizing channel 220 to prevent the atomizing channel 220 from affecting the assembly of the humidifying filter element 410. The humidifying filter element 410 is configured to adsorb the water in the water storage cavity and evaporate the water under the air flow drive of the air flow driving assembly 520 to form a humidifying air flow.

[0092] Optionally, the humidifying filter element 410 is inserted into the water tank 200 in the vertical direction, and there is a certain gap between the humidifying filter element 410 and the inner wall of the water tank 200. When there is water in the water tank 200, at least part of the humidifying filter element 410 is in contact with the water.

[0093] Optionally, the side wall of the water tank 200 is provided with an air inlet grille, so that the outside air can enter the water tank 200 through the air inlet grille, and then enter the air flow channel through the humidifying filter element 410. Among them, when the air flow passes through the humidifying filter element 410, the moisture adsorbed on the humidifying filter element 410 can be evaporated to form a humidifying air flow. The humidifying air flow can be driven by the air flow driving assembly 520 and discharged to the outside through the air flow channel to achieve evaporative humidification.

[0094] In some embodiments, referring to Figure 2 andFigure 6 The humidifying device may further include: a power supply device 420. Specifically, the power supply device 420 is electrically connected to the atomizing device 300 to control the start and stop of the atomizing device 300.

[0095] Optionally, when the humidifying device 400, such as the humidifying filter element 410, is installed in the water storage cavity, the power supply device 420 controls the atomizing device 300 to turn off. When the humidifying filter element 410 is detached from the water storage cavity, the power supply device 420 controls the atomizing device 300 to turn on.

[0096] By adopting the above technical solution, by setting the power supply device 420, the start and stop of the atomizing device 300 can be controlled, so as to realize the flexible switching of the humidifying device between the atomizing humidifying mode and the evaporation humidifying mode.

[0097] In some embodiments, the power supply device 420 may include: a trigger 421, a switch 422, and a power supply line. Among them, the trigger 421 is fixedly connected to the humidifying filter element 410, the power supply line is electrically connected to the atomizing device 300, and the switch 422 is arranged on the power supply line to control the on and off of the power supply line.

[0098] There is an installation position for placing the humidifying filter element 410 in the water storage cavity. When the humidifying filter element 410 is arranged at the installation position, the trigger 421 triggers the switch 422 to turn off the power supply line. When the humidifying filter element 410 is detached from the installation position, the trigger 421 triggers the switch 422 to turn on the power supply line.

[0099] Optionally, the trigger 421 is detachably connected to the humidifying filter element 410, such as by adhesion, so as to facilitate replacement when the trigger 421 is damaged.

[0100] Optionally, the switch 422 is installed on the inner side wall of the water storage cavity. When the switch 422 is in a natural state, the switch 422 controls the power supply line to be conductive. When the humidifying filter element 410 is in the installation position, the trigger 421 contacts the switch 422 and controls the switch 422 to turn off the power supply line.

[0101] By adopting the above technical solution, by setting the trigger 421, the switch 422, and the power supply line, the opening and closing of the atomizing device 300 can be controlled by adjusting the installation state of the humidifying device 400 in the water storage cavity, which is convenient for controlling the humidifying device 400 to switch between the atomizing humidifying mode and the evaporation humidifying mode.

[0102] In some embodiments, the placement position is located on the bottom wall of the water tank 200, and the triggering member 421 is provided on one side of the humidifying filter element 410 facing the bottom wall of the water tank 200. The switching member 422 and the power supply line are provided in the device main body 100. In this way, it can be ensured that the triggering member 421 is at the position closest to the atomization chamber 110 in the water tank 200, which is beneficial to ensuring the sensitivity of the triggering action.

[0103] Optionally, the bottom wall of the water tank 200 has a mounting groove, and the mounting groove is the mounting position. After the humidifying filter element 410 is installed in the water tank 200, the lower end portion of the humidifying filter element 410 is embedded in the mounting groove.

[0104] Optionally, the triggering member 421 is adhered to the bottom of the humidifying filter element 410, and the switching member 422 is located at the upper end portion of the device main body 100. When the triggering member 421 abuts against the bottom wall of the water tank 200, the triggering member 421 and the switching member 422 interact with each other to cause the switching member 422 to turn off the power supply line.

[0105] By adopting the above technical solution, by defining the positions of the triggering member 421, the switching member 422, and the power supply line, it is convenient to control the opening and closing state of the switching member 422 through the triggering member 421.

[0106] In some embodiments, the device main body 100 is located below the water tank 200 along the height direction of the humidifying device. That is, the device main body 100 can provide bottom support for the water tank 200.

[0107] An installation post 111 is provided in the atomization chamber 110. The installation post 111 can extend along the height direction of the humidifying device. The installation post 111 is spaced from the bottom wall of the water tank 200 to form an installation gap. The switching member 422 is provided in the installation gap and fixedly connected to the installation post 111. In other words, the switching member 422 is provided at the top end of the installation post 111. In this way, it can be ensured that the distance between the triggering member 421 and the switching member 422 is close enough to ensure the sensitivity of the triggering action.

[0108] Optionally, an installation cavity is provided on one side inside the device main body 100. The installation cavity is isolated from the atomization chamber 110. The installation post 111 is provided in the installation cavity, and the switching member 422 is fixedly provided on the installation post 111 to prevent the atomized gas in the atomization chamber 110 from contacting the switching member 422, thereby causing damage to the switching member 422.

[0109] By adopting the above technical solution, by arranging the device main body 100 below the water tank 200, it is convenient for the water in the water tank 200 to enter the device main body 100; by providing the installation post 111, it is convenient to arrange the switching member 422 in the device main body 100.
