具体地，在本发明实施方式中，走线空间122包括走线通道122a及安装空间122b。走线通道122a连接安装空间122b，电气件(图未示出)设置在安装空间122b内。电气件可包括电路板及设置在电路板上的电子装置。Specifically, in the embodiment of the present invention, thewiring space 122 includes awiring channel 122a and aninstallation space 122b. Thewiring channel 122a is connected to theinstallation space 122b, and electrical components (not shown in the figure) are arranged in theinstallation space 122b. The electrical components may include a circuit board and electronic devices disposed on the circuit board.

如此，电气件可与设置在走线通道122a内的连接线连接，走线通道122a的设置提高了用于无叶风扇的机头10的可设置空间，进一步增加了机头的其他功能，提升了用户体验。In this way, the electrical components can be connected to the connecting wires arranged in thewiring channel 122a, and the setting of thewiring channel 122a increases the space available for thehandpiece 10 for the bladeless fan, further increases other functions of the handpiece, and improves the user experience.

在一个实施方式中，安装空间122b位于用于无叶风扇的机头10的顶部位置，走线通道122a从用于无叶风扇的机头10的底部延伸到用于无叶风扇的机头10的顶部并与安装空间122b连通。In one embodiment, theinstallation space 122b is located at the top of thehandpiece 10 for a bladeless fan, and therouting channel 122a extends from the bottom of thehandpiece 10 for a bladeless fan to thehandpiece 10 for a bladeless fan and communicate with theinstallation space 122b.

如此，结构较为紧凑，充分利用了用于无叶风扇的机头10的可设置空间。In this way, the structure is relatively compact, and the space available for installation of thehandpiece 10 for the bladeless fan is fully utilized.

较佳地，走线通道122a设置成与用于无叶风扇的机头10的外侧边缘匹配的形状以使走线更便利。Preferably, thewire routing channel 122a is provided in a shape matching the outer edge of thehandpiece 10 for a bladeless fan to facilitate wire routing.

需要说明的是，安装空间122b也可以位于用于无叶风扇的机头10的其他位置，例如位于与出风部12相背的一侧，这样设置不影响出风部12的出风及风道121的设置，也可以位于用于无叶风扇的机头的底部等位置，即安装空间122b的位置可根据具体情况进行相应设置。It should be noted that theinstallation space 122b can also be located at other positions of themachine head 10 for the bladeless fan, for example, on the side opposite to theair outlet 12 , so that the setting does not affect the air outlet and air flow of theair outlet 12 . The arrangement of thechannel 121 may also be located at a position such as the bottom of the machine head used for the bladeless fan, that is, the location of theinstallation space 122b may be correspondingly arranged according to specific conditions.

请参阅图6，在一个示例中，电气件可为距离检测装置124，可以在安装空间122b内设置距离检测装置124，距离检测装置124可通过连接线与设置在走线空间122内或者设置在走线空间122外的第一控制单元125电性连接，距离检测装置124用于检测用户与安装有用于无叶风扇的机头10的无叶风扇之间的距离，当距离检测装置124检测到用户与无叶风扇之间的距离小于或等于设定距离时，第一控制单元125根据距离检测装置124的检测结果控制无叶风扇开启，以实现用于无叶风扇的机头10的自动送风。设定距离可以根据具体应用情况进行设置。距离检测装置124例如为红外光距离检测装置。Referring to FIG. 6 , in one example, the electrical component may be adistance detection device 124 , and thedistance detection device 124 may be arranged in theinstallation space 122 b , and thedistance detection device 124 may be arranged in thewiring space 122 through a connecting wire or arranged in Thefirst control unit 125 outside thewiring space 122 is electrically connected, and thedistance detection device 124 is used to detect the distance between the user and the bladeless fan on which thehandpiece 10 for the bladeless fan is installed. When the distance between the user and the bladeless fan is less than or equal to the set distance, thefirst control unit 125 controls the bladeless fan to turn on according to the detection result of thedistance detection device 124, so as to realize the automatic feeding of thehandpiece 10 for the bladeless fan. wind. The set distance can be set according to the specific application. Thedistance detection device 124 is, for example, an infrared light distance detection device.

在一个实施方式中，用于无叶风扇的机头10包括第一风道件14及第二风道件16。第一风道件14连接第二风道件16以形成出风部12。第一风道件14开设有出风口123。出风口123内设有间隔筋141以将出风口123间隔成多个风口123a。In one embodiment, thehandpiece 10 for a bladeless fan includes a firstair duct member 14 and a secondair duct member 16 . The firstair duct member 14 is connected to the secondair duct member 16 to form theair outlet portion 12 . The firstair duct member 14 is provided with anair outlet 123 . Theair outlet 123 is provided withspacer ribs 141 to space theair outlet 123 into a plurality ofair outlets 123a.

如此，通过第一风道件14连接第二风道件16的方式以形成出风部12，结构简单，便于制造，同时间隔筋141将出风口123间隔成多个风口123a，容易使得出风更加均匀，进而减少了气流的阻力。In this way, theair outlet 12 is formed by connecting the firstair duct member 14 to the secondair duct member 16 , which has a simple structure and is easy to manufacture. At the same time, thespacer ribs 141 separate theair outlet 123 into a plurality ofair outlets 123a, which is easy to make the air outlet. More uniform, which in turn reduces resistance to airflow.

在本发明实施方式中，出风口123为贯穿第一风道件14的壁的喷嘴。喷嘴呈缝隙状，以保证出风效果。间隔筋141将缝隙状的喷嘴间隔成多个呈长条状的风口123a。间隔筋141呈一字型排布，间隔筋141使得气流可顺着多个长条状的风口123a喷射出来，即间隔筋141还具有导流的作用。In the embodiment of the present invention, theair outlet 123 is a nozzle penetrating the wall of the firstair duct member 14 . The nozzle is slit-shaped to ensure the effect of air outlet. Thespacer rib 141 divides the slit-shaped nozzle into a plurality ofelongated tuyere ports 123a. Thespacer ribs 141 are arranged in a line shape, and thespacer ribs 141 enable the air flow to be ejected along the plurality of elongated tuyere 123a, that is, thespacer ribs 141 also have the function of guiding the flow.

在一个例子中，第一风道件14的外缘1411与第二风道件16的外侧可通过超声波焊接而连接在一起。In one example, theouter edge 1411 of the firstair duct member 14 and the outer side of the secondair duct member 16 may be connected together by ultrasonic welding.

在一个实施方式中，间隔筋141与第一风道件14为一体成型结构。In one embodiment, thespacing ribs 141 and the firstair duct member 14 are integrally formed.

如此，间隔筋141与第一风道件14为一体成型结构，可更容易使多个风口123a均匀，进而减少了气流的阻力，降低了无叶风扇的噪声，提升了用户体验。In this way, thespacer rib 141 and the firstair duct member 14 are integrally formed, which makes it easier to make the plurality ofair outlets 123a uniform, thereby reducing the resistance of the airflow, reducing the noise of the bladeless fan, and improving the user experience.

具体地，在一个例子中，第一风道件14可采用塑料制成。在制造第一风道件14时，可在模腔中与风口123a对应的位置放置入子，相邻两个入子间形成入子间隔。当成型材料注入模腔中时，成型材料填充入子间隔，待成型材料冷却脱模后，原来放置入子的位置形成风口123a，入子间隔形成间隔筋141。因此，通过设计入子间隔的参数，便能使所形成的多个风口123a尺寸基本相同，进而使得多个风口123a均匀，降低了无叶风扇的噪声，避免了在第一风道件14上焊接间隔筋141而造成风口123a不均匀的现象。Specifically, in one example, the firstair duct member 14 may be made of plastic. When manufacturing the firstair duct member 14 , the runners may be placed in the mold cavity at the positions corresponding to thetuyere 123 a , and a gap between the runners is formed between two adjacent runners. When the molding material is injected into the mold cavity, the molding material is filled into the sub-spaces, and after the molding material is cooled and demolded, thetuyere 123a is formed at the original position of the sub-injection, and thespacer ribs 141 are formed in the sub-sub-space. Therefore, by designing the parameters of the sub-interval, the size of the plurality ofair openings 123a can be made to be substantially the same, thereby making the plurality ofair openings 123a uniform, reducing the noise of the bladeless fan, and avoiding the firstair duct member 14. The unevenness of thetuyere 123a is caused by welding thespacer ribs 141 .

在一个实施方式中，用于无叶风扇的机头10包括第一风道件14及第二风道件16，第一风道件14连接第二风道件16以形成出风部12，第一风道件14的内表面14a设置有隔板142。隔板142围成线槽。第二风道件16与隔板142密封连接以与线槽形成走线空间122。In one embodiment, thehandpiece 10 for a bladeless fan includes a firstair duct member 14 and a secondair duct member 16 , the firstair duct member 14 is connected to the secondair duct member 16 to form theair outlet portion 12 , Theinner surface 14a of the firstair duct member 14 is provided with apartition plate 142 . Thebulkhead 142 encloses a wire slot. The secondair duct member 16 is hermetically connected with thepartition plate 142 to form awiring space 122 with the wire groove.

如此，隔板142与第二风道件16连接以形成密封的走线空间122的设置方式易于实现，且结构较为简单。In this way, the arrangement in which thepartition plate 142 is connected with the secondair duct member 16 to form the sealedwiring space 122 is easy to implement, and the structure is relatively simple.

在一个实施方式中，隔板142与第一风道件14为一体成型结构。In one embodiment, thebaffle 142 and the firstair duct member 14 are integrally formed.

如此，结构简单，便于加工，制造成本低。In this way, the structure is simple, the processing is convenient, and the manufacturing cost is low.

在一个实施方式中，第二风道件14与隔板142通过焊接的方式密封连接。In one embodiment, the secondair duct member 14 and thepartition plate 142 are sealedly connected by welding.

如此，工艺简单，制造成本较低，且适用性强。In this way, the process is simple, the manufacturing cost is low, and the applicability is strong.

具体地，在制作第一风道件14的隔板142时，可将隔板142的高度制作得大于与第二风道件16连接时的隔板142的高度。因此，可利用上述两者高度差所形成的隔板部分作为焊接的部分，并与第二风道件16达到密封连接。如此，有利于提高焊接效率，进而降低用于无叶风扇的机头10的成本。Specifically, when manufacturing thepartition plate 142 of the firstair duct member 14 , the height of thepartition plate 142 can be made larger than the height of thepartition plate 142 when connected with the secondair duct member 16 . Therefore, the part of the partition formed by the height difference between the two can be used as the welded part, and can be sealed with the secondair duct member 16 . In this way, it is beneficial to improve the welding efficiency, thereby reducing the cost of thehandpiece 10 for the bladeless fan.

在一个例子中，第二风道件16与隔板142可通过超声波焊接。In one example, the secondair duct member 16 and thebaffle 142 can be welded by ultrasonic waves.
