Description

A kind of Portable humidifier

Technical field

The utility model relates to a kind of air humidifying equipment, in particular to a kind of Portable humidifier.

Background technique

Chinese patent literature CN207510185U discloses a kind of multifunctional vehicle mounted humidifier on June 19th, 2018, And specifically disclose: including body, body is equipped with water tank assembly, atomising device and control circuit, passes through water suction in water tank assembly Plug is connected to atomising device, and the body is in the form of a column, and body is additionally provided with machine head assembly, and machine head assembly is arranged on water tank assembly Side；The atomising device is ultrasonic atomization piece, and the top of machine head assembly, machine head assembly top surface pair is arranged in ultrasonic atomization piece Ultrasonic atomization piece is answered to be equipped with atomizing nozzle, ultrasonic atomization piece is undertaken on water suction plug upper end, and water tank is protruded into water suction plug lower end In assembly.In the humidifier, machine head assembly is mutually detachably connected with water tank assembly, and machine head assembly is located on water tank assembly Side, water suction plug needs to have certain length and could be extended to by water tank assembly to be connect with the atomising device in machine head assembly, this Result in the material cost of water suction plug higher；And since water suction plug length is longer, the conveying path in water suction plug of liquid Diameter is longer, and liquid is readily volatilized in transmission process or even partially liq is rested on water suction plug and is not used, and leads to resource Waste；Furthermore, it is necessary to when dismantling water tank assembly progress liquid supplement, since machine head assembly does not have standing performance, so needing sleeping It is put in plane, inconvenient for operation, the part that the plug that in addition absorbs water is used to be inserted into water tank assembly exposes in air, in plane Impurity is easy pollution water suction plug, directly affects the using effect and service life of water suction plug.

For the usage experience for promoting humidifier, the humidifier with aromatherapy function has been gradually appeared in the market；Such as: Chinese patent Document number CN207257304U Vehicular aromatherapy humidifier disclosed on April 20th, 2018, and specifically disclose: including upper casing Body, upper skeleton, lower skeleton, lower case, water tank, fan and at least one atomizing piece, the water tank and lower case be fixedly linked and The water tank is removably attachable to except lower skeleton, at least one described atomizing piece is fixedly connected in lower skeleton, the wind Fan is fixedly connected in the upper housing and side of fan and offers the venthole being connected to inside and outside upper housing；It is opened on the upper skeleton Equipped with upper through-hole, the side wall of the upper through-hole is also provided with the side through hole being connected with the upper housing, opens on the lower skeleton Equipped with the lower through-hole being connected to upper through-hole；In this way, water, champignon liquid or other liquid can be filled first in water tank, then open simultaneously Fan and atomizing piece, so that " steam " after atomization successively passes through lower through-hole, upper through-hole, side through hole and venthole, and most Eventually outside outflow upper housing, interior air environment is humidified.The structure is mixed by the way that water tank directly is added in champignon liquid with water It closes, to reach champignon effect, but after being mixed due to champignon liquid with water, the concentration reduction of champignon liquid causes fragrance unobvious, and And champignon liquid may be chemically reacted with water, influence the property of champignon liquid, be unfavorable for storing for a long time.

Therefore, it is necessary to be further improved to existing humidifier.
