Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

Referring to fig. 1-2, the embodiment provides a mist outlet nozzle for a humidifier, and specifically, the mist outlet nozzle includes a mist outlet pipe 10, a connection end 11 and a mist outlet end 12 are respectively disposed at two ends of the mist outlet pipe 10, and the connection end 11 is used for connecting a mist chamber 20 of the humidifier; a mist outlet channel 13 is arranged between the connecting end 11 and the mist outlet end 12, and the flow area of the mist outlet channel 13 close to the mist outlet end 12 is larger than or equal to that close to the connecting end 11. Thus, at least part of the stages of the mist outlet passage 13 exhibit a tendency to gradually increase, and moreover, there is no tendency to decrease the flow area in the mist outlet direction.

Therefore, when the mist outlet nozzle is mounted on the humidifier, the mist enters the mist outlet channel 13 from the connecting end 11, passes through the mist outlet channel 13, and is ejected from the mist outlet end 12. Because the flow area of the mist outlet channel 13 near the mist outlet end 12 is larger than or equal to the flow area near the connecting end 11, the mist flowing through the mist outlet channel 13 is also restrained by the inner wall of the mist outlet channel 13, so that the mist sprayed from the mist outlet end 12 is in a gradually-increased circle shape. Therefore, the fog visual effect sprayed by the fog outlet nozzle is good, and the user experience is improved.

Wherein the mist outlet nozzle is shaped as a rotating body, so that the cross section of the mist outlet channel 13 is round.

In an embodiment, the mist outlet channel 13 includes a first channel 131 near the mist outlet end 12 and a second channel 132 near the connecting end 11, the flow area of the first channel 131 along the mist outlet direction is constant, the flow area of the second channel 132 along the mist outlet direction is gradually increased, and the inner wall of the second channel 132 may be provided as a tapered surface. The mist outlet direction is the bottom-to-top direction in the figure.

Of course, it is also possible to provide that the flow area of the second channel 132 along the mist outlet direction is constant, and the flow area of the first channel 131 along the mist outlet direction is gradually increased, and no corresponding figures are given in this application.

In an embodiment, the flow area of the mist outlet passage 13 in the mist outlet direction gradually increases. That is, the entire inner wall of the mist outlet passage 13 may be provided with a tapered surface.

In some embodiments, referring to fig. 2, the mist outlet channel 13 is a circular channel, the inner diameter of the mist outlet channel 13 at the mist outlet end 12 is d1, and d1 ranges from 30 to 60 mm. The skilled person has found that the fogging effect of d1 in this range is due to the d1 being less than 30mm and greater than 60mm of the fogging nozzle.

Preferably, d1 is in the range of 40-55 mm. For example, the value of d1 may be 42mm, 44mm, 46mm, 50mm, 52mm, 54mm, and the like.

In some embodiments, the inner diameter of the mist outlet channel 13 at the connecting end 11 is d2, wherein d2/d1 is more than or equal to 0.8 and less than or equal to 0.96. The skilled person finds that d1 and d2 have better fogging effect at the ratio.

Illustratively, d2/d1 equals 0.9 and d2/d1 equals 0.95.

In some embodiments, the distance from the connection end 11 to the mist outlet end 12 is L, which ranges from 40 to 60 mm. The skilled person has found that the fogging effect of L in the range 40-60mm is due to fogging nozzles outside this range.

Further, L ranges from 54 to 57 mm. For example, L may have a value of 55mm, 56mm, etc.

In some embodiments, the mist outlet nozzle further comprises a nozzle cap 30, the nozzle cap 30 being connected to the mist outlet end 12 and extending from the mist outlet end 12 outside the mist outlet pipe 10 towards the connection end 11. The nozzle cap 30 is arranged, so that the mist outlet nozzle can be taken conveniently, and convenience in installation is improved.

For example, the nozzle cap 30 may be provided in a circular arc curved shape.

Referring to fig. 3, the present embodiment provides a humidifier, which includes a mist chamber 20 for generating mist, a water tank 40 for containing water, and a mist outlet nozzle according to any embodiment of the present invention, wherein a mist generator is disposed in the mist chamber 20, the mist generator can atomize water in the water tank 40 into the mist chamber 20, and a connection end 11 of the mist outlet nozzle is connected to the mist chamber 20, so that the mist in the mist chamber 20 is sprayed out through the mist outlet nozzle.

In some embodiments, the humidifier further comprises a control mechanism for controlling the intermittent variation of the volume of the mist chamber 20, the control mechanism causing the mist in the mist chamber 20 to be ejected from the mist outlet nozzle by controlling the reduction of the volume of the mist chamber 20. The fog cavity 20 with the intermittently changed volume can enable the fog outlet nozzle to intermittently spray, so that independent fog circles are formed, and the ornamental value is improved.

In some embodiments, the humidifier also includes a gas supply mechanism for intermittently supplying gas to the mist chamber 20. The intermittent air supply of the air supply mechanism can enable the fog outlet nozzle to spray intermittently, so that independent fog rings are formed, and the ornamental value is improved.

In some embodiments, the top cover 41 of the water tank 40 is opened with a water filling opening 42; the mist cavity 20 is communicated with the mist outlet nozzle through a mist outlet connecting pipe 21, and the mist outlet connecting pipe 21 passes through the water filling port 42 to be communicated with the mist outlet nozzle. Accordingly, in the humidifier in use, the mist is present inside the mist outlet connection pipe 21 and water is present outside.

Wherein, the mist outlet pipe 10 is connected with a nozzle cap 30, and the nozzle cap 30 shields the water filling opening 42 above the water filling opening 42.

In some embodiments, referring to fig. 3, the top of the mist outlet nozzle is higher than the top of the water tank 40, and the top of the mist outlet nozzle may also be disposed flush with the top of the water tank 40, or lower than the top of the water tank 40.
