Description

Technical Field

[0001] The present application relates to the technical field of air purification equipment, and in particular to an air purifier with a humidification function. Background Art

[0002] An air purifier is a device used to purify indoor air. The filter in the air purifier absorbs dust, formaldehyde, and other pollutants, thereby purifying the air. To enhance the functionality of air purifiers, some models also include an integrated humidification function.

[0003] The Chinese patent with the existing announcement number CN210425353U discloses a humidifying air purifier, which includes a housing, the housing being provided with an air inlet and an air outlet; a filter assembly, an air duct assembly and a fan are provided in the housing; the filter assembly is located at the position of the air inlet for purifying air entering the housing; the air duct assembly is located at a position on the side of the filter assembly away from the air inlet, and a gap is provided between the air duct assembly and the filter element; the fan is located at a position of the air duct assembly away from the filter assembly, and the air outlet end of the fan assembly is aligned with the air outlet; an atomizing plate is provided in the housing below the fan, and a water tank is provided below the atomizing plate, the atomizing plate is connected to the water in the water tank through a water-absorbing cotton swab to atomize the water in the water tank to form water mist. The fan blows air toward the air outlet to form a negative pressure in the housing, thereby allowing gas outside the housing to enter the housing through the filter assembly; the air entering the housing is mixed with the water mist, flows through the air duct assembly and the fan, and is discharged from the air outlet, thereby achieving the effect of increasing the humidity of the purified air.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the humidified air flows through the fan, the water mist in the air can easily come into contact with the fan motor and other related electrical components used to drive the motor to rotate, which may cause the related electrical components to short-circuit or be corroded by the water mist and damaged, so it needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide an air purifier with a humidification function to improve the problem that electrical components such as motors in the air purifier are easily damaged by short circuits or corrosion due to water mist.

[0006] The air purifier with humidification function provided in this application adopts the following technical solution:

[0007] An air purifier with a humidifying function comprises a shell and an air purification device arranged in the shell; the shell is provided with a liquid storage box, and the liquid storage box is connected to an atomizing assembly for atomizing the liquid in the liquid storage box; the shell is provided with a mist outlet channel sealedly connected to the mist outlet end of the atomizing assembly, and the mist outlet channel is connected to the outside of the shell; the inner side wall of the mist outlet channel is provided with an air inlet hole, and the inner side wall of the air inlet hole is connected to a positive pressure source for blowing air into the air inlet hole, and the air inlet end of the positive pressure source is connected to the air purification device.

[0008] By adopting this technical solution, a positive pressure source blows the purified air from the air purifier into the mist outlet channel, driving the water mist in the mist outlet channel to quickly flow into the room. At the same time, the water mist humidifies the air flowing into the mist outlet channel, thereby increasing the air humidity. The mist outlet channel separates the water mist from the air purifier, reducing the risk of water mist contacting the electrical components of the air purifier, causing short circuits or damage due to water mist erosion.

[0009] Optionally, the mist outlet channel is extended upward at one end away from the atomization assembly; the inner side wall of the mist outlet channel located above the air inlet is provided with a water retaining bar, and the side of the water retaining bar close to the axis of the mist outlet channel is tilted downward.

[0010] By adopting the above technical solution, the upward extension of the atomization channel is conducive to ensuring the smooth flow of water mist; the water retaining bar can block the water flowing downward from the inner wall of the mist outlet channel, thereby reducing the possibility of water flowing along the inner wall of the air inlet hole toward the positive pressure source and the air purification device, so as to reduce the risk of water contacting the positive pressure source or the electrical components of the air purification device, which is conducive to ensuring the stability of the operation of the positive pressure source and the air purification device.

[0011] Optionally, an air guide plate is provided on the inner wall of the mist outlet channel located below the air inlet, and one end of the air guide plate close to the axis of the mist outlet channel is tilted upward; the upper end of the air guide plate is located on the side of the water retaining bar away from the air inlet.

[0012] By adopting the above technical solution, the air guide plate can guide the gas blown in from the air inlet upward, so that the gas drives the water mist to flow upward.

[0013] Optionally, the air guide plate is provided with a water leakage hole along the up-down direction, and the water leakage hole is located on a side of the water retaining bar close to the air inlet hole.

[0014] By adopting the above technical solution, the water falling from the water retaining strip onto the air guide plate can flow downward along the upper surface of the air guide plate and fall through the water leakage hole, thereby reducing the possibility of the water flowing into the air inlet hole.

[0015] Optionally, the liquid storage box includes a box body and a cover body provided on the box body, and a mist outlet hole is provided through the upper surface of the cover body; the atomization assembly is connected to the cover body, and the mist outlet end of the atomization assembly is aligned with the mist outlet hole; the shell is slidably provided with a receiving seat abutting the lower surface of the box body in the up and down directions, and the receiving seat is connected with an elastic member for driving it to move upward; the upper surface of the cover body is tightly abutted against the side wall of the shell provided with the mist outlet channel.

[0016] By adopting this technical solution, when adding liquid to the box, simply drag the box downward. When the upper end wall of the cover separates from the mounting plate, move the box away from the mounting plate to remove the housing. Similarly, when installing the box, place the lower end wall of the box against the upper surface of the receiving seat, then press the receiving seat downward to align the mist outlet hole in the cover with the mist outlet channel. Finally, release the box or receiving seat, and the elastic member automatically pushes against the receiving seat, tightening the upper surface of the cover against the mounting plate. Operation is simple and quick.

[0017] Optionally, the shell is provided with an adjustment seat at a position below the receiving seat that slides along the up and down directions, one end of the elastic member is fixed to the receiving seat, and the other end is fixed to the adjustment seat; the shell is rotatably provided with a rotating rod, and the peripheral wall of the rotating rod is provided with a receiving rod for abutting against the lower surface of the adjustment seat; the lower surface of the adjustment seat is provided with a receiving groove for accommodating the receiving rod after rotation; when the receiving rod is located in the receiving groove, the adjustment seat can move downward.

[0018] By adopting the above technical solution, rotating the rotating rod can align the receiving rod with the receiving groove, allowing the adjustment seat to move downward, thereby increasing the distance between the adjustment seat and the receiving seat, reducing the deformation of the elastic member, and facilitating the downward drag of the box body for removal. Before installing the box body, the receiving seat is pulled upward to drive the adjustment seat upward, thereby disengaging the receiving rod from the receiving groove; at this time, the rotating rod is rotated to allow the receiving rod to support the adjustment seat.

[0019] Optionally, the rotating rod is provided with a positioning block, and the shell is provided with an abutment block for abutting the positioning block; the rotating rod is connected to an elastic connecting member for driving the positioning block to rotate away from the abutment block; when the positioning block abuts the abutment block, the receiving rod is aligned with the accommodating groove.

[0020] By adopting the above technical solution, when the abutment block abuts the positioning block, the abutment block can limit the rotation of the rotating rod, thereby allowing the receiving rod to quickly align with the receiving groove. When the rotating rod is released, the elastic connecting member can drive the rotating rod to automatically return to its original position, making operation more convenient.

[0021] Optionally, the abutment block is provided with a magnetic part, and the positioning block is provided with an adsorption part for magnetically attracting the magnetic part; the adjustment seat is provided with a control part for separating the adsorption part from the magnetic part; when the adjustment seat moves to a position above the receiving rod, the control part automatically separates the adsorption part from the magnetic part.

[0022] By adopting this technical solution, the adsorption member and the magnetic member are magnetically attracted to each other, thereby fixing the rotating rod, thereby reducing the possibility that the receiving rod will abut against the inner wall of the receiving groove, which would prevent the adjustment seat from sliding down. When the adjustment seat moves upward, the control member can automatically separate the adsorption member and the magnetic member, making operation simple and convenient.

[0023] Optionally, the lower surface of the box body is provided with a plug-in slot, and the upper surface of the receiving seat is rotatably provided with a rotating seat for plugging into and cooperating with the plug-in slot, and the axial direction of the rotating shaft of the rotating seat is set along the length direction of the receiving seat; the shell is provided with a docking protrusion, and the upper end wall of the cover body is provided with a docking groove for inserting the docking protrusion.

[0024] By adopting the above technical solution, the docking seat and the insertion slot are plugged into each other, and the docking protrusion and the docking slot are plugged into each other, which facilitates the alignment of the mist outlet end of the atomizer assembly with the mist outlet channel, thereby facilitating the installation of the box body. When installing the box body, the rotating seat can be rotated outward to facilitate the lower end of the box body to be placed on the rotating seat; under the upward push of the elastic member, the box body is rotated inward; during the rotation of the box body, when the docking protrusion is aligned with the docking slot, the docking protrusion will automatically insert into the docking slot, making the operation convenient and labor-saving.

[0025] Optionally, a mounting ring groove is provided on the peripheral wall of the docking protrusion, and a sealing ring is embedded in the mounting ring groove for abutting against the inner side wall of the docking groove.

[0026] By adopting the above technical solution, the sealing ring can improve the sealing between the docking protrusion and the inner side wall of the docking groove, reducing the possibility of water mist leakage.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The mist outlet channel can separate the water mist from the air purification device, reducing the risk of water mist coming into contact with the electrical components of the air purification device, causing short circuits or damage to the related electrical components due to water mist corrosion;

[0029] 2. The water retaining strips and air guide plates cooperate to reduce the possibility of water mist flowing along the inner wall of the air inlet to the positive pressure source or air purification device, which helps to ensure the normal operation of the electrical components in the positive pressure source and air purification device;

[0030] 3. The rotating seat is rotatably connected to the receiving seat, which facilitates the installation and disassembly of the box body. BRIEF DESCRIPTION OF THE DRAWINGS
