In one embodiment, the leafless fan head 10 includes electrical components (not shown) disposed within the wiring space 161, the electrical components being coupled to the connecting wires.

In this way, the electrical component and the connecting line are directly integrated in the wiring space 161, which can increase the use function of the head 10 for the bladeless fan, and facilitate the intelligent design of the head 10 for the bladeless fan.

In some examples, the handpiece for a bladeless fan includes a mounting portion 102 formed on top of the first air duct member 16. The mounting portion 102 is provided with an installation space 161b. The mounting portion 102 is located at the top of the head 10 for the bladeless fan a raised portion that is raised downward.

In one embodiment, the head 10 for the bladeless fan is provided with a through hole 120. The electrical component is a distance detecting device that is exposed through the through hole 120 to detect the presence of an obstacle in front of the handpiece 10 for the bladeless fan.

In one embodiment, the inner surface 12c of the first air duct member 12 is provided with a partition 124. The partition 124 encloses a wire slot. The second duct member 14 is sealingly coupled to the partition 124 to form a wiring space 161 with the slot.

Thus, the manner in which the partition 124 is connected to the second air duct member 14 to form the sealed wiring space 161 is easy to implement, and the structure is relatively simple.

In one embodiment, the partition 124 is integrally formed with the first duct member 12.

Thus, the structure is simple, the processing is easy, and the manufacturing cost is low.

In one embodiment, the second duct member 14 is sealingly coupled to the diaphragm 124 by welding.

In this way, the process is simple, the manufacturing cost is low, and the applicability is strong.

Specifically, when the partition 124 of the first duct member 12 is formed, the height of the partition 124 can be made larger than the height of the partition 124 when the second duct member 14 is connected. Therefore, the partition portion formed by the above-described height difference can be utilized as a welded portion and is in sealing connection with the second duct member 14. In this way, it is advantageous to improve the welding efficiency, thereby reducing the cost of the head 10 for the bladeless fan.

In one example, the second duct member 14 and the diaphragm 124 can be ultrasonically welded.

In one embodiment, the first air duct member 12 is coupled to the second air duct member 14 to form the air outlet portion 11 and the air inlet portion 13. The air duct 16 is opened in the air outlet portion 11 and the air inlet portion 13. The air outlet portion 11 is provided with an air outlet 121. Air inlet portion 13 It is connected to one end of the air outlet portion 11, and the air inlet portion 13 is provided with an air inlet 131. The air duct 16 communicates with the air inlet 131 and the air outlet 121.

In addition, other functional components can be directly connected through the air inlet portion 13 to increase other functions of the handpiece and enhance the user experience.

Specifically, in the embodiment of the present invention, the air inlet portion 13 is located at the lower end of the head 10 for the bladeless fan, and the head 10 of the bladeless fan includes two opposite air inlets 131, and the two air inlets 131 are symmetrically disposed. On the inside of the head 10 of the bladeless fan, the airflow enters through the air inlet 131, flows downward from the air passage 16, and is then ejected by the air outlet 121.

It should be noted that the "lower end" and "inside" are the positional states of the noseless fan head 10 in the normal use state, such as the positional state of the noseless fan head 10 shown in FIG.

In one embodiment, the inner side surface of the air inlet 131 is formed with a positioning groove 133, and a positioning member (not shown) is disposed in the positioning groove 133.

In this way, the air inlet portion 13 can cooperate with the positioning slot 133 to realize the connection with other external functional components, so as to increase the rotatable function of the head and improve the user experience, and the matching structure of the positioning member and the positioning slot 133 is relatively Simple and easy to implement.

In an embodiment of the invention, the positioning member is an elastic positioning member. In this way, the elastic connection between the air inlet portion 13 and other external functional components can be realized by the positioning member, the connection is stable and the flexibility is high, and the configurable space of the head 10 of the bladeless fan is improved.

For example, the air inlet portion 13 is connected to the base of the bladeless fan mounted with the head 10 for the bladeless fan through the positioning member, and the blade 10 of the bladeless fan can be switched by the position of the positioning member to realize the bladeless fan. The angle of the head 10 is switched, so as to achieve the purpose of the air outlet 121 to supply air at different positions, thereby improving the user experience.

In one embodiment, the outer side surface of the air inlet portion 13 is formed with a fitting groove 134, and the engaging groove 134 is provided with a card member 1341.

In this way, the head 10 for the bladeless fan can realize the stable connection with the base of the bladeless fan by the cooperation of the engaging groove 134 and the card 1341, so as to achieve the fixing of the head position, thereby facilitating the use and improving the user experience.

In one embodiment, the end face of the air inlet portion is formed with an annular mounting groove 135 for placing a sealing ring (not shown). In this way, the head 10 for the bladeless fan can realize the airtight connection with the base of the bladeless fan through the cooperation of the mounting groove 135 and the sealing ring, so as to avoid air volume loss and noise caused by the air leakage of the machine head.

Specifically, a vent hole is formed corresponding to the base portion connected to the air inlet portion 13, and the outer edge of the base portion is provided with a sealing ring, when the head 10 for the bladeless fan is mounted on the pedestal, The base portion extends into the air inlet portion 13 from the air inlet 131, and the air inlet 131 communicates with the ventilation hole, and the sealing ring is received in the mounting groove 135 to seal the air inlet portion. At the junction with the pedestal, a gas-tight connection between the handpiece 10 and the pedestal is achieved.

Referring to FIGS. 11-14 together, in one embodiment, the inner surface 12c of the first air duct member 12 is provided with a flow guiding device 15. The flow guiding device 15 has a stepped structure, and the flow guiding device 15 is used to guide the airflow to the air outlet 123.

In this way, since the flow guiding device 15 is disposed obliquely toward the air outlet 121, the airflow can be smoothly flowed toward the air outlet 121 by the flow guiding device 15, thereby reducing the loss of gas in the flow and ensuring that the air is used for no leaf. The fan head 10 has the same air outlet effect and uniform direction of the airflow, and enhances the user experience.

Specifically, in the embodiment of the present invention, the flow guiding device 15 includes three steps 151 which are sequentially connected to form a stepped structure. Three steps 151 are disposed within the air duct 16. In the example of the present invention, the step 151 near the top position of the head 10 for the bladeless fan is closer to the distance from the air outlet 121 with respect to the step 151 near the position of the air inlet 131.

In this way, the airflow can be collected along the three steps 151 toward the air outlet 121, thereby effectively ensuring the uniformity of the air outlet and the direction of the airflow, and the structure of the flow guiding device 15 is relatively simple and easy to manufacture.

Taking the middle step 151 as an example, the step 151 includes three flow guiding surfaces, which are a first guiding surface 151a, a second guiding surface 151b, and a third guiding surface 151c, respectively. The third flow guiding surface 151c connects the first flow guiding surface 151a and the second flow guiding surface 151b. The three flow guiding surfaces are all outer surfaces of the stepped structure, and the first flow guiding surface 151a and the second flow guiding surface 151b are oriented toward the air outlet 121, and the three guiding surfaces are used for guiding the airflow to the air outlet 121. In this way, each step can fully utilize the three flow guiding surfaces to direct the airflow in the air duct 16 to the air outlet 121.

The structure of the other two steps is similar to that of the intermediate step and will not be developed in detail here.

In one embodiment, the air outlet portion 11 includes an arcuate flow guide 152 disposed within the air duct 16 that is coupled to the air inlet side of the air duct 16.

In this way, the curved deflector 152 enables the high-speed airflow to smoothly enter the air duct 121 to reduce the noise of the head 10, and also allows the airflow to enter the air duct 121 more concentratedly, thereby ensuring the inside of the air duct 121. The consistency of the flow direction of the airflow ensures the wind effect.
