For the atomizing and humidifying module 2 convenient for installing wires, for understanding the specific structure and working principle, the following details are described:

before the detailed description, the prior technical problems are briefly described. Firstly, an atomization humidification module is formed by assembling an upper shell and a lower shell, main parts such as an ultrasonic device, a power source, a PCB (printed Circuit Board) and the like are arranged in the lower shell, and then the upper shell is covered on the lower shell to realize the installation of the upper shell and the lower shell and shield and protect the parts; the second, then install some spare parts in last casing, another part is installed in the inferior valve, so avoid down the casing structure too complicated, and avoid the horizontal direction occupation area too big, thereby satisfy compact structure's requirement, but because the inside problem of walking the line that involves, when the PCB board is adorned in the inferior valve, the power supply is adorned in last casing, when the power supply passes through the wire and is connected with the PCB board electricity, need the skilled person to hold the last casing that will cover in inferior valve, then stretch out the hand or tweezers get into the region between the upper and lower casing, then connect the wire of power supply on the PCB board, whole process is comparatively inconvenient, because the last casing can cause certain operation hindrance and realization hindrance to wire connection. If the inconvenience is to be improved, the length of the wire is lengthened, so as to enlarge the distance between the upper and lower shells, and the upper and lower shells are covered after the wires are connected, but in this way, after the upper and lower shells are covered, the technician cannot clearly know what position the current wire is in and what state the wire is in, so that the wire is messy, the wire is inconvenient to manage, even the wire interferes with other components, the wire is damaged, and the like.

For this purpose, referring to fig. 3 to 5, the present utility model proposes an atomizing and humidifying module 2 for facilitating the installation of wiring, comprising:

a lower housing 21, a lower housing cavity 211 is formed in the lower housing 21;

an upper case 22, an upper case cavity 221 is formed in the upper case 22, and the upper case 22 is covered on the lower case 21 so that the upper case cavity 221 is communicated with the lower case cavity 211;

the power source 23, the power source 23 locates in upper shell cavity 221 and connects with the first wire terminal 24;

the PCB 25 is arranged in the lower shell cavity 211, and a first terminal port 251 is arranged on the PCB 25;

the first wire terminal 24 is inserted into the first terminal port 251, so that the power source 23 is electrically connected with the PCB 25, the upper housing 22 is provided with a blind socket 222 which is communicated with the upper housing cavity 221, and the projection of the first terminal port 251 and the projection of the first wire terminal 24 are located in the projection of the blind socket 222 along the direction of the lower housing 21 toward the upper housing 22.

The technical scheme provided by the utility model is mainly that the blind jack 222 communicated with the upper shell cavity 221 is formed, and the blind jack 222 corresponds to the positions of the first terminal port 251 and the first wire terminal 24, so that the first terminal port 251 and the first wire terminal 24 can be exposed through the blind jack 222, and then a worker can directly insert the first wire terminal 24 into the first terminal port 251 through the blind jack 222, thereby facilitating the wire insertion and installation of the worker. In detail, the upper shell 22 and the lower shell 21 are mainly used for installation and combination, and are divided into an upper shell cavity 221 and a lower shell cavity 211 which are communicated with each other, so that a part of components can be installed in the lower shell cavity 211, and a part of components, such as a power source 23, can be installed in the upper shell cavity 221, thereby enabling the structure of the atomization humidification module 2 to be more compact, saving the space in the horizontal direction and reducing the plane occupation area of the atomization humidification module 2; besides, since the power source 23 is installed in the upper housing cavity 221 of the upper housing 22 and the PCB 25 is installed in the lower housing cavity 211, when the upper housing 21 and the lower housing 21 are covered, there is a problem that the power source 23 and the PCB 25 are inconvenient to electrically connect. The upper and lower shells 21 are not covered, so that workers cannot operate the first wire terminal 24 and the first terminal opening 251 well for plugging, too long wires are not required to be reserved to be matched with the first wire terminal 24 to be plugged into the first terminal opening 251, and the conditions that wires are disordered due to too long length of the first wire terminal 24, and even interference, breakage and the like possibly occur after the upper and lower shells 21 are installed are avoided.

The power source 23 is a fan, and mainly blows atomized water mist to the external environment.

In some embodiments, referring to fig. 3 to 5, the upper case 22 is provided with a first threading hole 223 and a second threading hole 224. A bridge 225 for carrying the first wire terminal 24 is formed between the first wire hole 223 and the second wire hole 224. It should be noted that, the first wire terminal 24 includes two parts, i.e., a wire and a terminal, and the terminal is connected to one end of the wire facing away from the power source 23, and is mainly used for matching with the first terminal port 251, and all subsequent names of parts related to the wire terminal refer to that the wire and the terminal are integrated. The bridge 225 between the first and second string holes 223 and 224 is mainly formed by the structure of the upper case 22 itself. One end of the first wire terminal 24, which is far away from the power source 23, penetrates from the first threading hole 223 and then crosses the bridge 225, so that a part of the first wire terminal 24 is placed on the bridge 225, then penetrates from the second threading hole 224 and returns into the upper shell cavity 221, and continues to extend, so that one end with the terminal extends to the blind jack 222, and a subsequent technician can conveniently insert the first wire terminal 24 into the first terminal port 251 through the blind jack 222 on the basis of covering the upper shell 21 and the lower shell 21.

Further, the upper housing 22 is further provided with a wire-erecting hole 226, and a wire-erecting hook 227 is arranged at the wire-erecting hole 226. The wire-laying hook 227 is two oppositely disposed L-shaped hooks, which are connected to each other or are oppositely disposed but not in contact with each other with a certain gap therebetween, and together define a wire-laying area for carrying a wire, and the two oppositely disposed L-shaped hooks are combined in a U-shape. The gap width left is smaller than the diameter of the wire, preventing the first wire terminal 24 from falling out of the gap. The stringing area is located below the stringing hole 226 and communicates with the stringing hole 226. The first wire terminal 24 passes through the overhead line area, and a portion of the first wire terminal 24 located in the overhead line area is placed on the overhead line hook 227. Through utilizing the cooperation of overhead line hook 227 and overhead line hole 226, can conveniently manage the line to first wire terminal 24, prevent that the wire in the first wire terminal 24 from being mixed and disorderly distributes, also avoid first wire terminal 24 to rock.

For the entire plugging process of the first wire terminal 24, a brief description thereof is given below:

one end of the first wire terminal 24 facing away from the terminal is connected with the power source 23, the technician sequentially passes the other end of the terminal which is not yet connected through the first threading hole 223, the bridge 225, the second threading hole 224 and the stringing area, and continues to extend the wire to extend to the blind socket 222, then the terminal is connected to the wire, then the upper housing 22 is covered on the lower housing 21, and then the technician inserts the terminal of the first wire terminal 24 into the first terminal opening 251 by hands or tweezers or other tools. The whole process can ensure that the first wire terminal 24 does not have the waste of the wire length as much as possible, and the length of the wire is not increased for convenient installation, so that the subsequent wires are disordered. In addition, by matching the bridge 225 with the wire-setting hook 227, the first wire terminal 24 is always pulled according to a predetermined wire in the wire-setting process, and the first wire terminal 24 can be supported and fixed, so that the subsequent wire-setting process can be basically eliminated, and in the connection process, that is, the wire-setting process is already equivalent to the wire-setting process, and the situations of interference, wire damage and the like of the first wire terminal 24 after the upper and lower shells 21 are covered can be avoided. Because the entire cabling and the mounting of the upper and lower housings 21 are visible.

The linear distance between the first threading hole 223 and the blind jack 222 is larger than the linear distance between the second threading hole 224 and the blind jack 222, and the linear distance between the second wire and the blind jack 222 is larger than the linear distance between the wire-setting area and the blind jack 222. The straight line distances described herein are all measured based on the geometric center of each structure, such as the geometric center of the first threaded aperture 223, the geometric center of the second threaded aperture 224, the geometric center of the blind socket 222, and the geometric center of the stringing area. By the above definition, it is ensured that repeated routing does not occur during routing of the first wire terminal 24, resulting in waste of the length of the first wire terminal 24 and messy routing.

In some embodiments, the atomizing and humidifying module 2 further includes a water tank 26 and an ultrasonic device. The water tank 26 is disposed in the lower housing cavity 211, and the ultrasonic device is disposed in the water tank 26 and electrically connected to the PCB board 25 through the second wire terminal. The PCB 25 is provided with a second terminal opening, and a second wire terminal on the ultrasonic device is inserted into the second terminal opening, so that the ultrasonic device and the PCB 25 are electrically connected. One end of the second wire terminal is connected to the ultrasonic device, the other end of the second wire terminal surrounds the outside of the water tank 26, and the second wire terminal is wound to the top of the water tank 26 from the outside of the water tank 26 and then connected to the second terminal port, so that the second wire terminal is effectively prevented from being soaked in the water tank 26 for a long time. Besides, a wire clamping buckle is further arranged outside the water tank 26, and the second wire terminal passes through the wire clamping buckle when the water tank 26 is wound, so that the second wire terminal is fixed on the water tank 26, and the second wire terminal is prevented from shaking or being too disordered.

Further, the second wire terminal passes through the overhead wire area and extends to the blind receptacle 222. When the second wire terminal passes through the wire-laying area, the space of the wire-laying area is limited, and the first wire terminal 24 is arranged in the wire-laying area in a penetrating manner, so that when the second wire terminal passes through the wire-laying area, the second wire terminal can be abutted against the first wire terminal 24 due to the limitation of the space of the wire-laying area, further fixing of the first wire terminal 24 and the second wire terminal is sequentially realized, and the number of required openings in the wire-laying area can be reduced.

It should be noted that, the projection along the direction of the lower housing 21 toward the upper housing 22, the projection of the second terminal opening and the second wire terminal are located within the projection of the blind socket 222. So configured, after the upper and lower housings 21 are closed, the technician can still insert the second wire terminal into the second terminal opening by hand or by operating a tool.

In some embodiments, the atomizing and humidifying module further comprises a decorative cover 27, wherein the decorative cover 27 is arranged on the top of the upper shell 22 to cover a series of holes formed in the upper shell 22 and the exposed wires.
