Figure 3 A schematic view of a nozzle in an air cleaner according to the present application. Figures 1 to 3As shown, the air purifier of the present application comprises a body 1, a liquid storage cavity 9, a support 41, a base 42, a first atomization device 43 and a nozzle 7. The body 1 comprises an air inlet, an air outlet and a fan motor assembly 5 for generating a first air flow through the body 1. The liquid storage cavity 9 and the first atomization device 43 are both arranged below the body. In this embodiment, the body 1 is completely stacked above the liquid storage cavity 9. The first atomization device 43 atomizes the liquid in the liquid storage cavity 9 to form a second air flow. The support 41 supports the body 1, and the second air flow rises to the body through a first pipe 45 formed in the support 41. The nozzle 7 is used to receive and spray the first air flow and the second air flow from the body. The base 42 supports the support 41 and the liquid storage cavity 9, the first atomization device 43 is arranged in the base 42, and a second pipe 44 is arranged in the base 42 to guide the liquid in the liquid storage cavity 9 to the first atomization device 43.

[0057] In a preferred embodiment, the bottom of the liquid storage cavity 9 is provided with an outflow hole communicating with the second pipe 44, and the outflow hole or the second pipe 44 is provided with a controllable flow stop valve, but not limited thereto.

[0058] In a preferred embodiment, the first air flow and the second air flow are mixed with each other between the downstream of the fan motor assembly 5 and the upstream of the nozzle 7, thereby simplifying the air passage, but not limited thereto.

[0059] In a preferred embodiment, the first air flow and the second air flow are emitted after being mixed with each other before entering the nozzle 7, so that the first air flow and the second air flow are divided in the body, thereby avoiding the corrosion of the metal components such as the fan motor assembly 5 inside the body 1 by the humid second air flow, but not limited thereto.

[0060] In a preferred embodiment, the support 41 is a vertical hollow pipe, and a vertical first pipe 45 is arranged inside the support 41, but not limited thereto.

[0061] In a preferred embodiment, the fan motor assembly 5 comprises a horizontal motor, and the shell of the body 1 annularly surrounds the horizontal motor, the shell is cylindrical, and the shell is provided with a plurality of air inlet holes 11, but not limited thereto.

[0062] In a preferred embodiment, the nozzle 7 is a ring-shaped nozzle, the side of the nozzle 7 away from the body 1 is provided with air outlets 71 along the extension direction of the ring-shaped nozzle, and the rotation axis of the horizontal motor is perpendicular to the plane where the ring-shaped nozzle is located, but not limited thereto.

[0063] In a preferred embodiment, the first end of the body 1 is connected to a guide shroud 6. The guide shroud 6 guides the first airflow to the bottom of the nozzle 7 at least. Then, the first airflow is distributed along the internal air passage of the annular nozzle in the direction of anti-gravity to the inner side of each air outlet 71, and then emitted from the air outlet 71 into the nozzle 7, but not limited thereto.

[0064] In a preferred embodiment, the direction in which the fan motor assembly 5 generates the first airflow is perpendicular to the direction in which the first airflow moves in the nozzle 7, but is not limited thereto.

[0065] In a preferred embodiment, the body 1 is further provided with an air intake shroud 3 that communicates with the fan motor assembly 5. The air intake shroud 3 is separated from the outer casing by a filter 2, but this is not a limitation.

[0066] Figure 4 This is a schematic diagram of another air purifier according to the present invention. Figure 4 As shown, in order to counteract the vibration generated when the horizontal motor rotates at high speed, another type of air purifier uses an annular cavity 9' surrounding the support member 41 to store water. Since water has a high density, after surrounding the support member 41, the swaying of the support member 41 can be reduced, thus enhancing the stability of the whole machine.

[0067] The specific embodiments of the present invention are as follows:

[0068] When the air purifier is in humidifier mode, the water in the liquid storage chamber 9 is introduced into the first atomizing device 43 of the base 42 by gravity along the inclined second pipe 44. The water is atomized by the first atomizing device 43 to form a moist second airflow (i.e., water vapor). The second airflow can rise vertically along the first pipe 45 of the support member 41 to reach the body 1.

[0069] The horizontal motor in the fan motor assembly 5 within the body 1 rotates, drawing air into the body 1 through the circumferential air inlet 11. Air then passes through the filter 2 and air inlet shroud 3 before reaching the fan motor assembly 5, where it is emitted to form a first airflow. This first and second airflows are guided by the air guide shroud 6 into the bottom 7A of the nozzle 7. The first airflow then rises along the internal air passage of the annular nozzle in the anti-gravity direction from the top 7B of the nozzle 7, simultaneously dispersing to the various air outlets 71. The first and second airflows mix within the nozzle 7 before finally being emitted from the air outlets 71. This separation of the first and second airflows within the body prevents the humid second airflow from corroding metal components such as the fan motor assembly 5 inside the body 1, but is not a limitation thereof.

[0070] In another variant, the first and second air flows are both split in the body 1 and in the nozzle 7, and are emitted from different positions of the air outlet 71, the high flow rate of the first air flow being able to entrain the second air flow together towards the outside, but not exclusively.

[0071] In summary, the air purifier can increase the volume of the water tank of the bladeless fan through the laminated structure of the fan body and the liquid storage cavity, prolong the working time of the bladeless fan as a humidifier, and improve the user experience.

[0072] The above is a further detailed description of the present application in combination with specific preferred embodiments, and cannot be considered as limiting the specific implementation of the present application to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, a number of simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be considered as falling within the protection scope of the present application.
