Referring to fig. 1, 8A and 8B, a specific embodiment of the annular outlet structure will be described. Fig. 8A is a cross-sectional view of a first air outlet manner of the annular air outlet structure of the present invention; fig. 8B is a cross-sectional view of the second air-out mode of the annular air-out structure of the present invention.

As shown in fig. 1, 8A and 8B, the annular air outlet structure 12 includes an inner annular surface 121 and an outer annular surface 122, the outer annular surface 122 is disposed outside the inner annular surface 121 and surrounds the inner annular surface 121 to form an air outlet cavity, a first air outlet 123 is formed at a front end of the outer annular surface 122 (i.e., a right end in fig. 8A) and a front end of the inner annular surface 121 (i.e., a right end in fig. 8A), a second air outlet 124 is formed at a side surface of the outer annular surface 122, and a rear end of the outer annular surface 122 is connected to a rear end of the inner annular surface 121 in a closed manner. The first air outlet 123 is configured with a first blocking mechanism 125, and the first blocking mechanism 125 can selectively open or close the first air outlet 123. Similarly, a second blocking mechanism 126 is disposed at the second air outlet 124, and the second blocking mechanism 126 can selectively open or close the second air outlet 124. The bottom end of the outer annular surface 122 is further provided with a vent hole (not shown in the figure), and after the annular air outlet structure 12 is fixedly connected to the cylindrical shell 11, the air outlet cavity is communicated with the cylindrical shell 11 through the vent hole. The humidifying device 2 includes a water tank 21 and an atomizer 22, such as an ultrasonic atomizer or an air compression atomizer, disposed in the water tank 21, the water tank 21 is fixedly connected to the bottom of the inner annular surface 121, and the atomizer 22 can atomize the liquid in the water tank 21 into water mist.

It can be understood by those skilled in the art that although not specifically shown in the drawings of the present embodiment, the first blocking mechanism 125 and the second blocking mechanism 126 may be implemented in various manners as long as the arrangement is capable of effectively controlling the opening and closing of the first air outlet 123 and the second air outlet 124. For example, the first blocking mechanism 125 and/or the second blocking mechanism 126 may be implemented by controlling an annular blocking ring by a linear motor, and the linear motor drives the annular blocking ring to move back and forth in the air outlet cavity to implement opening and closing control of the first air outlet 123 and/or the second air outlet 124; or the linear motor can be replaced by a combination of a rotary motor, a gear rack, a chain and the like. For another example, the first blocking mechanism 125 and/or the second blocking mechanism 126 may achieve opening and closing control of the second air outlet 124 through an electromagnetic adsorption manner, that is, the blocking ring is made of a metal material, an electromagnetic coil is disposed in the air outlet cavity, an elastic element is disposed between the blocking ring and the inner annular surface 121 or the outer annular surface 122, when the electromagnetic coil is powered on, the electromagnetic coil generates magnetic force to attract the blocking ring, and the elastic element stores elastic potential energy, so as to open the first air outlet 123 or the second air outlet 124; when the electromagnetic coil is powered off, the retainer ring returns to the initial position under the action of the elastic piece to close the first air outlet 123 or the second air outlet 124.

In particular, an air guiding structure is further disposed on the inner annular surface 121 and/or the outer annular surface 122, and the air guiding structure is configured to gradually reduce the air outlet width at the air outlet. For example, the wind guiding structure adopts two arc plates as shown in fig. 8A or 8B, and the arrangement of the two arc plates gradually narrows the outlet widths of the first air outlet 123 and the second air outlet 124, so that when the air flow passes through the air outlet, a venturi effect is generated to accelerate the flow velocity, thereby realizing the spraying effect. When the air is sprayed, negative pressure is generated near the annular air outlet, and the negative pressure can attract air near the annular air outlet to flow together, so that the circulation of indoor air is realized, and the air supply quantity is effectively improved. Of course, the air guiding structure may also be any other arrangement manner as long as the arrangement manner can gradually narrow the air outlet width of the first air outlet 123 and/or the second air outlet 124, and details are not repeated herein.

Through set up annular air-out structure 12 at the top of column shell 11, set up first air outlet 123 and second air outlet 124 on the annular air-out structure 12 to first air outlet 123 and second air outlet 124 respectively dispose the separation blade mechanism, make the air conditioner possess brand-new air outlet structure and two kinds of air-out forms, spray mode and diffusion mode, the user can be based on needs nimble selection air-out mode. The spraying mode can realize the spraying air-out effect, the spraying range is far, and the air outlet quantity is larger; the diffusion mode is that the second air outlet 124 supplies air to two sides, the air supply area is wide, airflow can be formed indoors in an encircling mode, and circulation of indoor air is enhanced. In addition, the arrangement of the annular air outlet enables the air conditioner to be novel in structure, the iterative sealing idea of the traditional cabinet type air conditioner product is subverted, and the development change of the air conditioner is promoted. Through the bottom with water tank 21 fixed connection at interior annular surface 121 for the water smoke behind the atomizer 22 atomizing can be directly sent to indoor each corner with the air current mixture of air outlet exhaust, guarantees the humidification effect.
