As shown in fig. 1, a telescopic fast drying device comprises two main air ducts 1 and a plurality of auxiliary air ducts 2 connected between the two main air ducts 1. Each main air pipe 1 is formed by connecting a plurality of short ventilation pipes 3 and telescopic pipes 4 in a staggered manner, one end of each main air pipe 1 is closed, the other end of each main air pipe is opened, and the opened end can be used as a fan opening to insert a blower.

Introduce below the utility model discloses the telescopic weathers efficiency of device fast and models and device detail design.
In order to scientifically determine the number of the auxiliary air pipes, the number of the air holes and the aperture and realize the optimal air blowing and air drying efficiency, the relationship among the number of the air holes, the aperture, the number of the auxiliary air pipes and the air blowing efficiency is obtained through precise theoretical derivation and mathematical calculation, the air speed and the temperature at each position of the whole device are approximately stable while the optimal air blowing efficiency is achieved, and heat can be uniformly distributed on the whole body of a subject.
The utility model discloses a weather efficiency modeling and analytic process as follows:
1. problem assumption and simplification
(1) The length of the air pipe does not cause energy loss, and the frictional resistance of the air pipe to the air is ignored;
(2) when the air enters the auxiliary air pipe from the main air pipe and is blown out from the air holes, the included angle between the main air pipe and the auxiliary air pipe is set to be 90 degrees. A macroscopic schematic of blow-drying efficiency modeling is shown in fig. 2.
2. Problem analysis
By examining the relevant literature on fluid mechanics, it was found that the liquid flow and the air flow are in many cases identical in character, and that the hydraulic radius in the case of water transport is also applicable in the case of air flow, so that the secondary air duct and the air hole size are analyzed on the basis of the hydraulic radius analysis.
According to the related knowledge of hydrodynamics, the equivalent diameter of wind in the air pipe is approximately equal to the diameter of the wind when the wind blows, so that the diameter of the main air pipe can be the diameter of the air opening of the blower in order to reduce the loss of wind energy and improve the utilization efficiency of the wind energy.
Increasing the number of wind holes increases the wind coverage density, but decreases the wind intensity per wind hole. In order to ensure that wind energy covers the whole situation relatively uniformly, the wind holes are arranged in a staggered mode, and the angle of the outlet wind blown out from the wind holes is measured and calculated through experiments, so that the distance between two adjacent wind holes under the optimal condition can be obtained.
In conclusion, for a specific problem of arrangement of a certain air pipe and air holes, parameters such as the diameter and the number of the auxiliary air pipes, the aperture and the number of the air holes and the like under the optimal condition can be obtained by only knowing the diameter of the air opening of the blower and giving the length of the auxiliary air pipe.
3. Modeling
Two adjacent auxiliary air pipes are mutually parallel, and air holes on two sides are arranged in a relative staggered mode. The convection of wind causes unnecessary energy loss, but the wind energy needs to be ensured to be effectively covered globally, so that the effective coverage area of each wind hole is paved like paving tiles in the area needing to be covered, namely, the wind is covered globally under the condition of reducing the energy loss.
Fig. 3 is a schematic view of wind direction and wind direction coverage of the wind holes, and fig. 4 is a microscopic view of the wind direction of the wind holes.
for example, for a typical diameter of 0.1-0.5 cm, the coverage angle α of a household blower (power about 1600W) blown by air is about 17 degrees (see FIG. 4), and the effective blowing distance is about 10 cm.
(1) Model for calculating distance between adjacent wind holes
The distance calculation formula of two adjacent air holes is as follows:
d is 2s × tan α + r (formula 1)
wherein d is the distance between two adjacent air holes, s is the efficient blowing distance, α is the coverage angle after the air is blown out, and r is the diameter of the air hole.
(2) Quantity model of auxiliary air pipes
Too many secondary air pipes can lead to smaller air quantity in the air pipes, but the effective range of the air needs to be ensured to cover the whole situation, so the distance between two adjacent secondary air pipes is s.
The calculation formula of the number of the auxiliary air pipes is as follows:
N-L/s-1 (formula 2)
And N is the number of auxiliary air pipes on the main air pipe, L is the length of the main air pipe, and s is the efficient blowing distance.
The number of the secondary air ducts is at least 3, preferably 3-8.
(3) Model for number of air holes on auxiliary air pipe
The optimal wind hole layout is the effective coverage area of all wind holes, and all areas are covered exactly without repetition as much as possible. Since the length of the secondary air duct should be the minimum of a reasonable range, which is determined according to the required coverage area, such as the torso portion of a common pet cat or dog, can be approximately seen as a cylinder. Thus, the length of the secondary air duct may be about the circumference of the cylinder. Therefore, the length of the secondary air duct can be regarded as a constant.
The number of the air holes on the auxiliary air pipe is calculated according to the formula:
wherein n is the number of the air holes on a single auxiliary air pipe, l is the length of the auxiliary air pipe, and d is the distance between two adjacent air holes.
(4) Auxiliary duct diameter and air hole diameter model
According to the definition of the hydraulic radius, the following can be known:
wherein Rs is the hydraulic radius, D0Is the main tube diameter.
Hydraulic radius, refers to the optimal diameter of the secondary pipe in water transport problems. The hydraulic radius Rs in this formula corresponds to the optimal secondary duct diameter, D0The diameter of the main air pipe is equivalent to that of the auxiliary air pipe, and the relationship between the auxiliary air pipe and the air holes is similar to that between the main air pipe and the auxiliary air pipe. Thus, the available secondary duct diameters are as follows:
wherein, R is the diameter of the auxiliary air pipe, and D is the diameter of the main air pipe.
The relationship between the air holes and the auxiliary air pipes is similar to that between the auxiliary air pipes and the main air pipes. Therefore, the calculation formula of the wind hole diameter is as follows:
wherein R is the diameter of the air hole, R is the diameter of the auxiliary air pipe, and R is the diameter of the air holesIs the hydraulic radius, and D is the diameter of the main air pipe.
According to the above description and illustration, the utility model discloses a telescopic weathers device fast, main tuber pipe is designed as the telescopic form, and vice tuber pipe has good elasticity, therefore can adapt to different sizes and the object of equidimension not, has good adaptability.
