Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic diagram of a mist outlet in a mist outlet structure of a humidifier according to an exemplary embodiment. Referring to fig. 1, the humidifier mist outlet structure includes a body 1 having a hollow structure, and a mist outlet passage 4 defined by an inner wall of the body 1. And comprises a mist inlet at the bottom and a mist outlet at the top. The mist outlet passage 4 gradually decreases in a direction from the mist inlet toward the mist outlet. In the disclosed exemplary embodiments, the mist may be water mist, but the disclosed exemplary embodiments are not limited thereto. For example, in other exemplary embodiments, the mist may be a mist formed from any aqueous liquid.

In an exemplary embodiment, for example, the body 1 may be a circular truncated cone whose cross-sectional shape in a plane perpendicular to the vertical direction is circular. For example, the body 1 may be prismatic, in which case its cross-section is polygonal. Wherein the cross-section may be of different shape, but the area of the mist inlet is larger than the area of the mist outlet. For example, when the body 1 is in the shape of a circular truncated cone, the hydrophobic effect can be improved by changing the radius proportional relationship between the top circle and the bottom circle of the circular truncated cone, wherein the smaller the ratio of the radius of the top circle to the radius of the bottom circle, the better the hydrophobic effect.

The embodiment of this disclosure provides a humidifier goes out fog mouth structure: the fog outlet channel 4 of the body 1 is designed into a shape with the cross section gradually reduced from bottom to top, when water drops at the fog outlet of the humidifier are slightly condensed, the water drops naturally flow back to the water tank due to the fact that the water drops are increased by gravity component force, water mist is prevented from being condensed to form large water drops, water blockage at the fog outlet of the humidifier is avoided, and user experience is greatly improved.

In the exemplary embodiment, the mist outlet channel 4 extends in a vertical direction. For example, the mist outlet passage 4 may extend vertically upward from the horizontal plane. For example, the mist outlet channel 4 may also extend in a direction forming an included angle with the vertical direction, the included angle may be 5 ° or 10 °, and the included angle is not limited here and may be designed according to actual needs.

In the exemplary embodiment, the body 1 is trumpet-shaped. Wherein the mist outlet passage 4 tapers in a direction from the mist inlet towards the mist outlet, it will be appreciated that the tapering may be linear, such as the frustoconical body 1 mentioned in the above embodiments. The tapering can also be non-linear, for example, if the body 1 is flared, in which case the tapering is non-linear. Moreover, the gradient of the inner wall of the mist outlet channel 4 can be designed according to the accumulated water amount of different positions of the mist outlet channel 4, and the improvement of the hydrophobic effect is facilitated.

In an exemplary embodiment, for example, the mist outlet openings of the mist outlet passage 4 may have a curved-sided pattern, and may also have a triangular or polygonal shape. For example, the mist outlet of the mist outlet channel 4 may be sausage-shaped.

For example, there may be one mist outlet of the mist outlet passage 4, or a partition may be provided at the mist outlet to divide the mist outlet into a plurality of smaller outlets. For example, the mist outlet may be divided into four smaller outlets.

Fig. 2 is an enlarged schematic view of an inner wall of a body in a mist outlet structure of a humidifier according to an exemplary embodiment. Referring to fig. 2, in an exemplary embodiment, the inner wall of the body 1 is provided with a first array structure 3 for increasing roughness. That is, the first array structure 3 is provided on the inner wall of the body 1 in the humidifier mist outlet structure of the exemplary embodiment shown in fig. 1.

In an exemplary embodiment, the first array structure 3 includes one or more of a dot structure, a honeycomb structure, a pillar structure, and an island structure.

For example, a honeycomb structure can be arranged on the inner wall of the body 1 by drilling to increase the roughness; for example, a frosting process may be used to arrange dot-shaped structures on the inner wall of the body 1; for example, a columnar structure or an island-shaped structure may be arranged on the inner wall of the body 1 by using an injection molding process; for example, a film-coating or plating process may be used to change the roughness of the inner wall of the body 1. The actual roughness can be selected as required, and even the roughness can be set according to the mist outlets of different models and different height positions in the mist outlets, so that the hydrophobic effect is improved.

It should be noted that the theoretical basis is that there are two interfaces where water drops contact on a rough surface: the interface between the water drop and the solid and the interface between the water drop and the air cushion formed by the fact that the water drop cannot enter the micropores due to the capillary phenomenon to form the air cushion; therefore, when the inner wall of the body 1 is provided with a dot structure, a honeycomb structure, a columnar structure or an island structure, the contact angle between the water drop and the contact surface can be increased, so that the water drop can rapidly slide off under the action of gravity, the water mist at the mist outlet of the humidifier is prevented from being condensed to form the water drop, and the problem of water blockage at the mist outlet is avoided.

Fig. 3 is an enlarged schematic view of an inner wall of a body in a mist outlet structure of a humidifier according to yet another exemplary embodiment. Referring to fig. 3, in the exemplary embodiment, a plurality of water-guiding strips 2 are arranged circumferentially along the inner wall of the body 1, each water-guiding strip 2 extending in the direction of the mist outlet channel. For example, the cross section of the water guide strip 2 in the plane perpendicular to the extending direction may be a triangle, a polygon or a curved pattern, and may be designed correspondingly according to different mist outlets; the water guide strip 2 is made of the same material as the body 1, and the water guide strip and the body can be processed by adopting an integral forming technology. Because the area of contact of water droplet and the inner wall of fog outlet is bigger, after setting up water guide strip 2, the area of contact of water droplet and water guide strip 2 is then less, thereby each water droplet meets after will attract rapidly, cover and reduce the interface potential energy, under the action of gravity, the water droplet landing rapidly to prevent that the water smoke of humidifier fog outlet from condensing and forming the water droplet, cause the production of the stifled water problem of fog outlet.

In the exemplary embodiment, the water conducting strips 2 are arranged in an array circumferentially along the inner wall of the body 1. For example, each water guide strip 2 extends from the mist outlet to the mist inlet position.

In the exemplary embodiment, the distance between the side of each water guiding strip 2 close to the water mist and the inner wall of the body 1 remains the same, i.e. the water guiding strips 2 themselves remain the same width up and down in the direction perpendicular to the inner wall. So set up, can make one side that each water conservancy diversion strip 2 is close to the axis of body 1 still keep reducing gradually from bottom to top, promptly, fog outlet channel 4 reduces gradually in the direction from the fog import to the fog export. This is advantageous in that the water drops slide off rapidly.

In the exemplary embodiment, each water guide strip 2 is provided with a second array structure on its surface for increasing roughness. That is, the second array structure is provided on the water guide strips 2 on the inner wall of the body 1 in the mist outlet structure of the humidifier of the exemplary embodiment shown in fig. 3.

In an exemplary embodiment, the second array structure includes one or more of a dot structure, a honeycomb structure, a pillar structure, and an island structure.

For example, in a certain embodiment, the humidifier mist outlet structure comprises a body 1 having a hollow structure, and a mist outlet passage 4 defined by an inner wall of the body 1. And comprises a mist inlet at the bottom and a mist outlet at the top. The mist outlet passage 4 gradually decreases in a direction from the mist inlet toward the mist outlet. Wherein, the fog outlet channel 4 extends in the vertical direction, and the fog outlet channel 4 extends vertically and upwards with the horizontal plane. Wherein the body 1 is trumpet-shaped. Wherein, the fog outlet of the fog outlet channel 4 is in a sausage shape. Wherein the inner wall of the body 1 is provided with a first array structure 3 for increasing the roughness. That is, the first array structure 3 is provided on the inner wall of the body 1 in the humidifier mist outlet structure of the exemplary embodiment shown in fig. 1.

Wherein the first array structure 3 is a dot-like structure. Wherein, arrange a plurality of water guide strips 2 along the inner wall circumference of body 1, every water guide strip 2 all extends along the direction of axis. The cross section of the water guide strip 2 in a plane vertical to the extending direction is triangular; the water guide strip 2 is made of the same material as the body 1 and is processed by adopting an integral forming technology. Wherein, the water guide strips 2 are arranged in an array along the circumferential direction of the inner wall of the body 1, and each water guide strip 2 extends from an outlet to an inlet. Wherein, the distance between one side of each water guide strip 2 close to the water mist and the inner wall of the body 1 is kept the same, namely, the water guide strips 2 are kept to be the same in width up and down in the direction vertical to the inner wall. Wherein, the surface of each water guide strip 2 is provided with a second array structure for increasing the roughness. That is, the second array structure is provided on the water guide strips 2 on the inner wall of the body 1 in the mist outlet structure of the humidifier of the exemplary embodiment shown in fig. 3.

Wherein the second array structure may be the same as the first array structure 3, for example, both are dot structures; for example, the second array structure may be different from the first array structure 3; for example, the first array structure 3 is a dot-like structure and the second array structure is a honeycomb structure. For example, a honeycomb structure can be arranged on the surface of the water guide strip 2 in a drilling manner to increase the roughness; for example, a frosting process may be adopted to arrange a dot structure on the surface of the water guide strip 2; for example, a columnar structure or an island-shaped structure may be arranged on the surface of the water guide strip 2 by using an injection molding process; for example, a film-coating or plating process may be used to change the roughness of the surface of the water guide strip 2. The actual roughness can be selected as required, and even the roughness can be set according to the mist outlets of different models and different height positions in the mist outlets, so that the hydrophobic effect is improved.
