Based on the described embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without requiring creative effort are also within the scope of protection of the present invention.

[0036] like Figures 1 to 7 As shown, the embodiment of the present application discloses a blowing device 7 with an extension tube, comprising:

[0037] The blowing channel 1 comprises a channel housing 101 with a curvature;

[0038] The blowing module 2 is embedded in the channel housing 101;

[0039] The blowing extension tube 3 includes a blowing extension hose 301 and a blowing extension hard tube 302. The blowing extension hose 301 and the blowing extension hard tube 302 are connected to each other, and one end of the blowing extension hose 301 is connected to the end of the blowing channel 1. The blowing module 2 is started and generates flowing wind in the blowing channel 1, and one end of the blowing extension hard tube 302 blows air outward.

[0040] Among them, the blowing channel 1 can be formed by two symmetrical and identical left and right channel shells 1012. The outer surface of each channel shell 101 is provided with a connection position, and each connection position is symmetrical. The connection position can be penetrated by a connecting piece, such as a bolt. In this way, each channel shell 101 can be fixedly connected to form a channel shell 101. In addition, the channel shell 101 is set to a shell with a curvature, which has a sound-absorbing effect. Specifically, when the air flow passes through the curved blowing channel 1, the tangential acceleration of the curve causes the air flow to rotate, forming a rotating gas layer, avoiding the direct impact of the air flow, thereby achieving the sound-absorbing effect, and also having the ability to ensure that the wind force is more concentrated and strong during the blowing process, specifically by changing the direction and intensity of the wind force, so that the wind force is more evenly and effectively distributed in the channel; the blowing module 2 can be a device for generating flowing wind composed of a centrifugal motor. The working principle of the centrifugal motor is based on centrifugal force, and the object is driven by the centrifugal force generated during rotation. Move or produce effect, wherein a blowing module 2 can be set in the opening at the middle position enclosed by the channel shell 101, and the blowing module 2 can be embedded and installed in the interior of the blowing shell. At its internal position, the activation of the blowing module 2 will generate corresponding flowing wind; the length setting of the blowing extension tube 3 can be determined according to needs, and it can be divided into a blowing extension hose 301 and a blowing extension hard tube 302. The blowing extension hose 301 and the blowing extension hard tube 302 are connected to each other. The blowing extension hose 301 can transmit the flowing wind in the blowing channel 1 to the blowing extension hard tube 302, and finally the blowing extension hard tube 302 blows air to the outside. The blowing extension hard tube 302 can be set in the form of a straight tube, which is convenient for manual operation by users and can reduce the loss of wind force. The blowing extension hose 301 can bring the corresponding blowing extension hard tube 302 to the target area according to needs (the length of the blowing extension hose 301 is set longer than the blowing extension hard tube 302, and the setting of the hose is conducive to stretching);

[0041] In this embodiment, the structural setting of the blowing device 7 with an extension tube can blow various small objects such as leaves, broken grass and snow distributed in the courtyard area to the target area. In this way, the longer blowing distance can be used to blow air to every corner of the courtyard area (the blowing device 7 with the extension tube is not movable, and its corresponding pipe can be moved to achieve long-distance blowing), ensuring the cleanliness of the courtyard area and improving the overall aesthetic effect of the courtyard environment. At the same time, it will not directly affect the user's walking, thereby improving the user's experience.

[0042] It should be noted that after the robot corresponding to the blowing device performs automatic cleaning first, the robot of the blowing device 7 with the extension tube manually cleans the specific target area, which can further ensure the cleanliness of the entire courtyard area.

[0043] like Figure 4As shown, in some embodiments, the blowing extension hose 301 is connected to the blowing channel 1 through a connecting pipe 4, and the two ends of the connecting pipe 4 are respectively mounted on one end of the blowing extension hose 301 and the blowing channel 1, and a fixing ring 3025 is provided between the blowing extension hose 301 and the blowing channel 1.

[0044] The butt joint is used to connect the extension hose 301 to the blowing channel 1 through the connecting pipe 4. By connecting the two pipes, the flowing air can be transmitted between the two pipes. The fixing ring is a ring-shaped structure that can fix the connection between the extension hose 301 and the blowing channel 1.

[0045] The design of the connecting tube 4 in this embodiment makes the connection between the wind extension hose and the blowing channel 1 more flexible, which is conducive to installation and disassembly. The two ends of the connecting tube 4 are respectively mounted on one end of the wind extension hose and the blowing channel 1, which is conducive to forming a good sealing effect and preventing leakage of flowing air.

[0046] like Figure 2 and Figure 4 As shown, in some embodiments, a card slot 5 is provided on the inner wall of the connecting pipe 4, and a protrusion 6 is provided on the outer wall corresponding to the card slot 5, and the card slot 5 is engaged with a card connector 8 provided on the inner wall of the blowing channel 1.

[0047] Among them, the card slot 5 can be set on the inner wall of the blowing channel 1, and the setting shape of the card slot 5 can be determined according to specific installation requirements. In this embodiment, an L-shaped card slot 5 can be selected, and a protrusion 6 is provided on the outer wall of the blowing channel 1 corresponding to the card slot 5. The clamping member 8 can be a nut or other various forms of clamping members 8 installed on the inside of the blowing channel 1. The clamping member 8 can be clamped into the inside of the card slot 5 to achieve a fixed connection between the blowing channel 1 and the connecting pipe 4; the number of the card slots 5 can also be determined according to specific requirements. In this embodiment, two card slots 5 with a symmetrical relationship can be set;

[0048] This embodiment provides the card slot 5 and the card connector 8 to ensure that the connection between the extension hose 301 and the blowing channel 1 is tighter and more reliable, and is not easy to loosen or fall off. At the same time, the setting of the protrusion 6 is convenient for users to disassemble based on the protrusion 6.

[0049] like Figure 2 and Figure 4 As shown, in some embodiments, the card slot 5 includes a first card slot 501 and a second card slot 502 that penetrate each other, and the clamping member 8 enters the second card slot 502 along the first card slot 501 for clamping.

[0050] The connecting tube 4 is connected to the blowing channel, and one of them can be placed on either one. After rotating one of them at a certain angle, the clamping member 8 will be clamped into the clamping slot 5. In this embodiment, the clamping member 8 is clamped into the clamping slot 5 in the following manner: after aligning the connecting tube 4 with the blowing channel, one of them is placed on the other, and then the clamping member 8 is moved along the shape of the L-shaped clamping slot 5, that is, along the first clamping slot 501 into the second clamping slot 502 until the clamping member 8 is located in the second clamping slot 502 of the L-shaped clamping slot 5.

[0051] In this embodiment, the clamping groove 5 can increase the clamping stability of the clamping member 8 .

[0052] like Figure 5 As shown, in some embodiments, the hair dryer extension tube 302 includes an extended handheld tube 3021, the other end of the hair dryer extension hose 301 is sleeved on the extended handheld tube 3021, and a fixing ring 3025 is provided between the hair dryer extension hose 301 and the extended handheld tube 3021.

[0053] The extended handheld hard tube 3021 is the middle section of the blowing device 7 with an extension tube, and the setting of the tube is also connected to one end of the extended handheld hose; the fixing ring is a ring structure, which can fix the connection between the extension hose 301 and the extended handheld hard tube 3021;

[0054] The provision of extending the handheld hard tube 3021 in this embodiment is to facilitate the user to manually control the blowing direction so as to clean the objects to be cleaned in the target area.

[0055] like Figure 5 As shown, in some embodiments, a handheld handle 3022 is arranged on the outer wall of the extended handheld rigid tube 3021, and the handheld handle 3022 includes a fixing part 30221 and a handle 30222 fixedly connected to the fixing part 30221, and the fixing part 30221 is fixedly connected to the outer wall of the extended handheld rigid tube 3021, and the handle 30222 is inclined relative to the fixing part 30221.

[0056] The hand-held handle 3022 is composed of a fixing part 30221 and a fixing part 30221. The fixing part 30221 may include a base and a ring structure, which is fixedly connected to the outer wall of the extended hand-held hard tube 3021. An installation position for the handle 30222 to be plugged in is provided inside the fixing part 30221. The handle 30222 can be configured to be a structure that is conducive to the user's hand gripping, such as a position for placing fingers on the surface of the handle 30222. In addition, the handle 30222 is tilted relative to the fixing part 30221, which is conducive to the user's hand gripping and manual control of the direction.

[0057] The inclined design of the handle 30222 in this embodiment is more in line with the natural posture of human hand holding, reduces fatigue of the hands, wrists and forearms, and allows users to maintain comfort even after long-term use. It is also beneficial for users to hold the extended handheld tube 3021 more stably, reducing accidents caused by improper operation or hand sliding. In addition, it is also beneficial to more easily control the blowing direction and improve the accuracy and efficiency of the operation.

[0058] like Figure 2 and Figure 6 As shown, in some embodiments, the hair-drying extension tube 302 includes an extended docking tube 3023, a card slot is provided inside the extended docking tube 3023, a protrusion 6 is provided on the outer wall corresponding to the card slot, and the card slot is engaged with the clamping part 8 provided on the inner wall of the extended handheld tube 3021.

[0059] The card slot and protrusion 6 mentioned in this embodiment are consistent with the above-mentioned blowing channel 1, and the card connector 8 is also consistent with the blowing channel 1. They will not be repeated here. This time, the extended docking tube 3023 is docked with the extended handheld hard tube 3021 (such as the extended handheld hard tube 3021 can be mounted on the extended docking tube 3023). In addition, the extended docking tube 3023 is also a docking tube. The purpose of its setting is to increase the extension distance of the hard tube, which is conducive to increasing the manual movement distance of the pipeline.

[0060] It should be noted that in Figure 6 There also exists Figure 4 Corresponding first card slot 501 and second card slot 502 .

[0061] like Figure 2 and Figure 7 As shown, in some embodiments, the blowing extension hard tube 302 includes a blowing head tube 3024, and the blowing head tube 3024 is provided with a blowing port 30241 and a blowing sleeve 30242, the aperture size of the blowing port 30241 is smaller than the aperture size of the blowing sleeve 30242, and the blowing sleeve 30242 is clamped to the extended docking tube 3023.

[0062] Among them, the blowing head pipe 3024 can be the pipe at the last end of the blowing direction, and the blowing sleeve 30242 provided therein is connected to the extended docking pipe 3023. The clamping form can adopt the clamping form of the clamping groove and the clamping member 8 mentioned above. Specifically, a clamping groove can be provided on the inner wall of the end of the blowing head pipe 3024 close to the blowing sleeve 30242, and a clamping member 8 can be provided on the inner part of the end of the connecting pipe 4 close to the blowing sleeve 30242 to achieve a fixed connection between the blowing head pipe 3024 and the connecting pipe 4. The air outlet of the blowing outlet 30241 can be set to a circular hole shape;

[0063] The aperture of the blowing port 30241 of this embodiment is smaller than that of the blowing sleeve. When the flowing wind enters from the blowing sleeve and passes through the blowing port 30241, the wind force will be focused and enhanced, making the blown wind more concentrated and powerful.

[0064] It should be noted that in Figure 7 The inner wall of the hair dryer head tube 3024 is provided with a card slot 5, and the outer wall of the hair dryer head tube 3024 corresponding to the card slot 5 is provided with a protrusion 6, and the card slot 5 is connected to the card connector 8 provided on the inner wall of the extended butt tube 3023; Figure 4 Corresponding first card slot 501 and second card slot 502 .
