As shown in fig. 7, the barrel 10 of the hair dryer of the present embodiment can supply air to the outside for drying the pet's body. After the wind is discharged from the air blowing port 12 at the front end of the air blowing cylinder 10, the airflow discharged from the air blowing port 12 can blow the hair of the pet, when the hair of the pet is blown, a small part of the hair of the pet can be blown away, and the environment is further polluted, for solving the problem, the guide body 20 is arranged at the air blowing port 12, because the air is a fluid, the air can deviate along the guide arc surface 21 of the guide body 20, and finally the wind discharged from the air blowing port 12 is guided to one side of the collecting cylinder 30, at the moment, if the airflow has water drops, dust, hair and the like, the air can be collected through the collecting cylinder 30, the effects of impurity separation and collection are achieved, and the pollution to the environment is reduced.
The structure of the blowing device according to the present embodiment, which is further detailed, will be described in detail.
In this embodiment, the flow guiding body 20 and the blowing cylinder 10 are integrally formed, and the collecting cylinder 30 is movably disposed relative to the flow guiding body 20, so that an included angle between the blowing opening 12 and the collecting inlet 32 is changed, and the specific structure thereof is as follows:
the flow guiding body 20 is cylindrical, rotating shafts 40 are arranged at two ends of the flow guiding body 20, and a plane formed by the longitudinal axis of the collecting channel 31 and the longitudinal axis of the blowing channel 11 is perpendicular to the rotating shafts 40. Connecting arms 41 are respectively arranged on two sides of the collecting cylinder 30, the collecting cylinder 30 is movably connected with the rotating shaft 40 through the two connecting arms 41, and the change of the included angle between the air blowing opening 12 and the collecting inlet 32 is realized through the rotation of the connecting arms 41 relative to the rotating shaft 40. When the air exhaust speed of the air blowing tube 10 and the collected impurities are changed, the impurity collection effect can be more optimized by adjusting the included angle between the air blowing port 12 and the collection inlet 32.
In use, the angle between the air outlet 12 and the collection inlet 32 may be adjusted, preferably: the angle between the air blowing opening 12 and the collection inlet 32 is less than 90 degrees. It will be appreciated that a fixed angle between the outlet 12 and the collection inlet 32 of the blowing device may be used, the preferred range of angles being: the angle between the air blowing opening 12 and the collection inlet 32 is less than 90 degrees.
In the present embodiment, the front end portion of the air blowing cylinder 10 is flat, and preferably, has a flat structure, and the air blowing port 12 is a flat air port, and correspondingly, the collection inlet 32 of the collection cylinder 30 is also flat.
One side of the blowing opening 12 of the blowing cylinder 10 forms a first cutting edge 13, one side of the collecting inlet 32 of the collecting cylinder 30 forms a second cutting edge 34, and the first cutting edge 13 and the second cutting edge 34 are respectively arranged tangentially to the cylindrical current carrier 20. The flat air blowing opening 12 and the collection inlet 32 are adopted, and the flat air blowing opening 12 is used for reducing the cross section area of the air blowing opening 12 to converge air flow and increase the flow speed; simultaneously, all blown air flows are enabled to be attached to the air guide arc surface 21 as much as possible, so that the air flows are introduced into the collection inlet 32; furthermore, as the velocity of the non-viscous fluid increases, the pressure energy or the sum of the potential energy of the fluid decreases, and the outside of the air blowing port 12 has a lower pressure than the surrounding air, thereby drawing in and blowing the surrounding impurities into the collecting inlet 32. To further enhance the effect of collecting the foreign substances, the cross-sectional area of the collection inlet 32 is larger than the cross-sectional area of the air blowing port 12, and preferably, the cross-sectional area of the collection inlet 32 is more than twice the cross-sectional area of the air blowing port 12.
It is to be understood that the collecting inlet 32 of the collecting cylinder 30 is not necessarily limited to a flat structure, and the flat structure is more adopted to correspond to the width of the air blowing port 12 and to reduce the size in the thickness direction thereof, and the collecting inlet 32 of the collecting cylinder 30 may be adopted to have a rectangular structure, and may also be adopted to have a square, circular or other shape.
As shown in fig. 5, the flow guiding arc surface 21 includes a smooth surface 211 and a concave-convex surface 212, the smooth surface 211 is close to the side of the air blowing opening 12, the concave-convex surface 212 is close to the side of the collecting inlet 32, and a plurality of flow guiding pits 2121 are distributed on the concave-convex surface 212, which has the effect as shown in fig. 8, by providing the flow guiding pits 2121, when the airflow passes through the concave-convex surface 212 of the flow guiding arc surface 21, an airflow vortex is formed at the position of the flow guiding pits 2121, so as to suppress the shunting of the airflow and the flow guiding arc surface 21, and ensure that more airflow discharged from the air blowing opening 12 flows to the collecting inlet 32 of the collecting cylinder 30 through the flow guiding arc surface 21, because the airflow discharged from the air blowing opening 12 is closer to the flow guiding arc surface 21 at an initial stage, in this embodiment, the plurality of flow guiding pits 2121 may be only disposed at a position far from the side of the air blowing opening 12.
The flow guide recesses 2121 are divided into a plurality of groups, and the flow guide recesses 2121 in each group of flow guide recesses 2121 are arranged at equal intervals along a straight line, which is parallel to the axial direction of the cylindrical flow guide body 20.
It will be appreciated that a collection outlet 33 is also provided in the collection canister 30, the collection outlet 33 being located at the opposite end of the collection inlet 32, and that a filter screen may or may not be provided for collecting dust or hair, but merely for collecting water droplets or the like in the air flow.
The air guiding arc 21 is close to the air blowing opening 12 on one side and the collecting inlet 32 on the other side, and it can be understood that according to suitable variants of the present embodiment, at least the following possibilities exist:
1. the diversion arc surface 21 and the air blowing opening 12 and/or the collection inlet 32 can be fixedly connected;
2. the air-guiding arc 21 and the air-blowing opening 12 and/or the collection inlet 32 may be in contact without connection;
3. the air guiding arc surface 21 and the air blowing opening 12 and/or the collecting inlet 32 may be in a non-contact manner without affecting the function, for example, a slight gap is formed between the two.
The purpose of the above embodiments is to reproduce and derive the technical solutions of the present invention exemplarily, and to describe the technical solutions, the purposes and the effects of the present invention completely, which aims to make the public understand the disclosure of the present invention more thoroughly and comprehensively, and not to limit the protection scope of the present invention.
The above embodiments are not intended to be exhaustive list of the present invention, and there may be many other embodiments not listed. Any replacement and improvement made on the basis of not violating the conception of the utility model belong to the protection scope of the utility model.
