[0017] Compared with the prior art, the technical scheme of the utility model has the following technical effects:

[0018] (1) The humidifying device comprises a handheld portable fan device which is composed of a handheld rod suitable for being held by a user and a fan movably connected with the handheld rod. The handheld rod is movably connected with the shell of the humidifying device and is suitable to be detached from the shell, so that the user can switch the use scene of the handheld portable fan device according to needs: when the user needs to use the humidifying device, the handheld portable fan device can be kept mounted on the shell and the mist diffusion capacity can be enhanced by adjusting the angle position and height position of the fan relative to the mist outlet; when the user does not need to use the humidifying device or does not need to enhance the mist diffusion capacity, the handheld portable fan device can be detached and used by hand or carried.

[0019] Further, the fan structure of the humidifying device realizes functional reuse, has the ability to enhance mist diffusion, and also has the function of a handheld portable fan, which is more flexible and provides more use scenes for the user, enriches the function points of the humidifying device, and relatively reduces the direct cost of introducing the fan, thereby improving the overall product power.

[0020] In addition, since the handheld rod and the humidifying device shell can be relatively moved, the handheld rod and the fan can also be relatively moved, and the adjustment freedom of the two-stage configuration makes the handheld portable fan device can adjust the mist flow direction and flow rate of the mist outlet, and can more fully meet the user's self-adjustment needs, and the adjustment ability of the mist diffusion effect is stronger.

[0021] (2) The humidifying device ensures efficient generation and stable discharge of mist through the coordinated design of the atomization structure, the fan and the water tank, and maintains the basic humidifier function.

[0022] (3) The assembly groove of the handheld rod and the shell is in sliding cooperation, which is simple to operate and facilitates the user to detach and assemble the handheld portable fan device. Further, the friction fit design of the two not only realizes stepless adjustment of the height of the handheld rod relative to the shell, but also simplifies the user's operation of assembling and detaching the handheld rod, and the user can complete the assembly and detachment by sliding the handheld rod to the appropriate position.

[0023] In addition, the sliding cooperation of the handheld rod and the shell along the height direction of the shell also allows the user to adjust the height of the handheld rod and the fan relative to the shell, so that the air outlet range is more matched with the mist column height formed by the mist outlet, and the diffusion effect is better.

[0024] (4) The handheld portable fan device comprises a power supply with a charging battery, thereby meeting the independent use needs of the handheld portable fan device. In addition, when the handheld portable fan device is assembled to the shell of the humidifying device, the charging male seat in the assembly groove can also charge the charging battery, thereby meeting the endurance needs of the independent use of the handheld portable fan device. In addition, the direct docking manner of the two is also convenient for the user to operate.

[0025] (5) The assembly groove is formed by a concave structure arranged on the side wall of the shell and matches the shape of the handheld rod, so that the appearance consistency of the entire humidifying device is strong, and the influence of the introduced fan on the appearance of the humidifying device is reduced.

[0026] In addition, the assembly groove and the handheld rod are matched with each other through the guide structure, facilitating the assembly and disassembly of the handheld portable fan device by the user.

[0027] (6) The handheld rod is configured as a telescopic sleeve rod, which can further reduce the volume occupation when handheld and improve portability.

[0028] In addition, the handheld rod is rotatably connected with the fan through a rotating shaft or a ball head connector, which is convenient for the user to adjust the relative position of the two, thereby adjusting the angle of mist diffusion or the angle of air flow when handheld, and is also convenient for the user to fold according to the need, so as to further compress the volume occupation of the handheld portable fan device when carrying.

[0029] (7) The design of the shell receiving groove enables the fan to be folded and stored above the top wall of the shell, which can reduce the volume occupation when the handheld portable fan device is assembled to the shell, and make the appearance consistency of the humidifying device stronger and more beautiful.

[0030] (8) Through the cooperation of the lifting mechanism, the steering mechanism and the control device, the handheld portable fan device can be adjusted according to the mist output, so as to more intelligently control the flow direction and / or flow rate of the mist. For example, when the mist output is large, the fan speed can be increased, or the relative height of the fan can be adjusted to make the air outlet range more matched with the height of the mist column formed by the mist outlet, or the angle of the fan can be adjusted to be more opposite to the mist column formed by the mist outlet, so as to have better and more precise mist diffusion adjustment effect.

[0031] (9) The angle of the fan relative to the handheld rod is adjustable within the range of 30°-150°, covering the mist diffusion needs of multiple scenes and meeting the user's adjustment of the diffusion angle, such as forward diffusion or upward diffusion or downward diffusion.

[0032] (10) By limiting the horizontal distance between the handheld rod and the mist outlet, it can avoid the poor diffusion effect caused by the too close distance between the two, and also avoid the backflow of the mist interfering with the running stability of the fan.

[0047] Embodiment 1

[0048] With reference to Figures 1-6 The present embodiment provides a diffusion humidifying device with a portable fan, which comprises a shell 1, an atomizing device (not shown in the figure) and a handheld portable fan device 2.

[0049] The inside of the shell 1 is used to install the atomizing device, since the present application is not optimized to improve the atomization and other basic functions of the humidifier, therefore for the shell 1 of the humidifying device, the external structure is mainly modified to facilitate cooperation with the handheld portable fan device 2, and the internal structure of the humidifying device or the shell 1 is not excessively limited or demonstrated, and in the specific implementation, the existing technology can be used for specific construction. The external structure of the shell 1 is mainly introduced below.

[0050] The shell 1 of the present embodiment is in a cylindrical structure, of course, in other embodiments, it can also be a cube or other geometric structure. In Figure 6As can be seen, the shell 1 has a side wall 11 and a top wall 12, the top wall 12 being detachable from the side wall 11 to allow a user to add water into the shell 1. The top wall 12 is provided with mist outlets 13 to discharge the mist, in the embodiment, the mist outlets 13 on the top wall 12 have two types, including first mist outlets in arc strip configuration, and two second mist outlets in small round hole configuration, the arrangement of the two types of mist outlets can also meet the user's adjustment of the amount of mist, and in the preferred structure, the top wall 12 is also provided with a receiving groove 121 at the position corresponding to the first mist outlet. Referring to Figures 3-4 , the side wall 11 is recessed inwardly into a concave structure at a preset position opposite to the mist outlet 13, the concave structure constitutes an assembly groove 111 extending along the height direction of the shell 1, the assembly groove 111 is provided with a silica gel strip having friction characteristics and also extending along the height direction, the silica gel strip forms a first guide structure 112. In the embodiment, the assembly groove 111 is formed in the side wall 11 of the shell 1. Of course, in other embodiments, the assembly groove can also be formed in the top wall 12 of the shell 1 and extend in the horizontal direction. Further, the assembly groove 111 is also formed with a charging male seat (not shown in the figure).

[0051] The atomization device is arranged in the shell 1 (not shown in the figure) and includes an atomization structure, a fan and a water tank, the atomization structure is used to generate mist, the fan is used to drive the mist to be discharged from the mist outlet 13, and the water tank is communicated with the inlet of the atomization structure. As described above, the atomization function of the humidifying device is not modified in the utility model, so the atomization device as a whole can also use the prior art, which will not be described in detail.

[0052] The handheld portable fan device 2 includes a handheld rod 21 and a fan 22.

[0053] The handheld rod 21 is integrally shaped with the concave structure, so that the cross-sectional shape of the handheld rod 21 and the shell 1 in the height direction is adapted to each other. The handheld rod 21 is adapted to be slidably arranged in the assembly groove 111 to achieve a movable connection with the shell 1. Specifically, the top of the assembly groove 111 is open and the bottom is closed, so that the handheld rod 21 can be inserted into the assembly groove 111 from the top of the shell 1 to achieve assembly, or extracted from the assembly groove 111 upward to take out the handheld portable fan device 2. In the actual structure, the handheld rod 21 can establish a friction fit relationship with the silica gel strip in the assembly groove 111, so that it can be slid relative to the assembly groove 111 and fixed at any height position, simplifying the user's operation of assembling and disassembling the handheld rod 21. Because the cross-sectional shape of the two in the height direction is adapted to each other, when the handheld rod 21 is inserted into the assembly groove 111 to achieve assembly, the two adapted to each other make the appearance consistency of the entire humidifying device high, reducing the influence of the introduction of the fan 22 on the appearance of the humidifying device. Further, the handheld rod 21 is also provided with a guide groove corresponding to the silica gel strip, which constitutes a second guide structure 211 cooperating with the first guide structure 112, facilitating the user's assembly and disassembly operation. In other preferred embodiments, the handheld rod 21 can also be configured as a telescopic sleeve rod (not shown in the figure), which has a structure similar to a telescopic selfie stick, and can be further stored when it is in a disassembled state relative to the shell 1.

[0054] The fan 22 is movably connected with the handheld rod 21 through a rotating shaft, and in other embodiments, it can also be movably connected through a ball joint connector. Further, the user can assemble the handheld portable fan device 2 on the shell 1, and adjust the angle of the fan 22, so that the inlet side or the outlet side of the fan 22 is adapted to face the mist outlet 13, to control the flow direction and / or flow rate of the mist discharged through the mist outlet 13, thereby enhancing the mist diffusion capacity, as shown in Figures 1-2 . Or, the handheld portable fan device 2 is removed from the shell 1 for handheld use or carrying, as shown in Figure 4 . Of course, since the handheld rod 21 can be fixed at any height position relative to the shell 1 in the height direction, when the handheld portable fan device 2 is assembled on the shell 1, the overall height of the handheld portable fan device 2 can also be adjusted according to the user's needs, as shown in Figure 3 , so that the fan 22 outlet range and the mist column height formed by the mist outlet 13 are more matched, thereby controlling the flow direction and / or flow rate of the mist, and the diffusion effect of the mist is better, for example, when the mist amount is large, the handheld rod 21 is slid upward to adjust the height of the handheld portable fan device 2 for use. In this embodiment, the size and shape of the fan 22 are adapted to the storage groove 121 on the top wall 12 of the shell 1, so that when the handheld rod 21 is assembled on the shell 1, the fan 22 can be folded relative to the handheld rod 21 and covered in the storage groove 121, as shown in Figure 5As shown, the fan 22 is accommodated without using the fan 22, the volume occupation is reduced, and the appearance consistency of the humidifying device is stronger, and the aesthetic degree is higher. Further, the handheld portable fan device 2 further comprises a power supply (not shown in the figure), and the power supply comprises a charging female seat (not shown in the figure) arranged at the lower end of the handheld rod 21 and a charging battery (not shown in the figure) arranged in the handheld rod 21. The charging battery can be used to power the fan 22 when the handheld rod 21 is not arranged on the shell 1, thereby meeting the demand of independent use of the handheld portable fan device 2. The cooperation of the charging male seat and the charging female seat can also meet the endurance demand of independent use of the handheld portable fan device 2.

[0055] In the specific structure, the included angle between the center line of the air outlet surface of the fan 22 and the center line of the mist outlet 13 is configured to be adjusted in the angle range of 30° to 150°. The user can adjust the angle of the fan 22 relative to the handheld rod 21, thereby adjusting the angle of the fan 22 relative to the shell 1 and the mist outlet 13, such as Figure 2 As shown, the mist is diffused forward or upward or downward, thereby meeting the adjustment of the diffusion angle by the user. In addition, when the handheld rod 21 is arranged on the shell 1, since the mist outlets 13 are arranged on the other side of the top wall 12 opposite to the assembly groove 111, the horizontal distance d between the handheld rod 21 and the mist outlet 13 is greater than or equal to L. Wherein, L is the distance from the geometric center of the cross-sectional shape of the shell 1 in the height direction to the edge, that is, greater than or equal to the radius of the cylindrical shell 1, or greater than or equal to 1 / 2 of the corresponding side length of the cubic shell 1. The embodiment limits the horizontal distance between the handheld rod 21 and the mist outlet 13, avoids the poor diffusion effect caused by the too close distance between the two, and also avoids the backflow of the mist interfering with the running stability of the fan 22.

[0056] The handheld rod 21 of the humidifying device is movably connected with the shell 1 and is adapted to be detached from the shell 1, so that the user can switch the use scene of the handheld portable fan device 2 according to the need: when the user needs to use the humidifying device, the handheld portable fan device 2 can be arranged on the shell 1, and the diffusion capacity of the mist can be strengthened by adjusting the angle position and the height position of the fan 22 relative to the mist outlet; when the user does not need to use the humidifying device or does not need to strengthen the diffusion capacity of the mist, the handheld portable fan device 2 can be taken off and used or carried.

[0057] Further, the structure of the fan 22 of the humidifying device can realize functional reuse, that is, the fan 22 has the ability to strengthen the diffusion of the mist and also has the function of the handheld portable fan device 2, the function is more flexible, more use scenes are provided for the user, the function points of the humidifying device are enriched, the direct cost caused by the introduction of the fan 22 is relatively reduced, and the overall product power is improved.

[0058] In addition, since the handheld rod 21 and the humidifying device shell 1 can be relatively moved, and the handheld rod 21 and the fan 22 can also be relatively moved, the two-stage configuration has the adjustment freedom, so that the handheld portable fan device 2 can adjust the mist flow direction and the flow rate of the mist outlet 13, and can more meet the self-adjustment demand of the user, and has stronger adjustment ability for the mist diffusion effect.

[0059] Embodiment 2

[0060] The embodiment has the same overall structure as the embodiment, and the difference lies in that the embodiment provides a more intelligent mist diffusion adjustment scheme.

[0061] Specifically, on the basis of the embodiment 1 and the related drawings, the fan 22 is configured as a speed-regulating fan, the handheld rod 21 and the fan 22 are connected through a steering mechanism, and the handheld rod 21 and the shell 1 are connected through a lifting mechanism, so that the height adjustment between the handheld rod 21 and the shell 1 and the angle adjustment of the handheld rod 21 and the fan 22 are both configured as electric adjustment. Correspondingly, the humidifying device further comprises a control device, and the control device is adapted to adjust the fan speed of the fan 22, the height of the handheld rod 21 relative to the shell 1, and / or the angle of the fan 22 relative to the handheld rod 21 according to the mist outlet condition, so as to control the flow direction and / or the flow rate of the mist discharged through the mist outlet 13.

[0062] The embodiment can adjust the handheld portable fan device 2 according to the mist outlet condition through the cooperation of the lifting mechanism, the steering mechanism and the control device, so as to more intelligently control the flow direction and / or the flow rate of the mist. For example, when the mist outlet amount is large, the fan speed of the fan 22 can be increased, or the relative height of the fan 22 can be adjusted to make the fan outlet range more matched with the mist column height formed by the mist outlet 13, or the angle of the fan 22 can be adjusted to more directly face the mist column formed by the mist outlet 13, so as to have better and more accurate mist diffusion adjustment effect.

[0063] In specific implementation, the lifting mechanism can adopt the existing technology, for example, the lifting drive of the handheld rod 21 is realized through the transmission of a motor and a screw rod to realize the height adjustment, and correspondingly, an abutting structure abutting against the screw rod to be driven by the screw rod can be arranged at the bottom of the handheld rod 21. The steering mechanism can also adopt the existing technology, for example, a reduction motor is directly used, which is powered by the power supply of the handheld portable fan device 2, and directly drives the fan 22 to rotate relative to the handheld rod 21 to realize the angle adjustment. In addition, corresponding switches can also be arranged on the humidifying device, and the existing triggering mode can be used to realize the action triggering of the steering mechanism and the lifting structure.

[0064] The above only describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application.
