Firstly, the traditional blower has low blowing efficiency, quick heat dissipation and large energy loss. Second, the blower may generate a loud noise, which is more audible to the pet than to humans, and the noise of the blower may cause discomfort to the pet or even fear it. Third, the blower has high wind power and high temperature, and if the user of the blower is unskilled in operation, even the distance between the blower and the pet is sometimes not noticed, or the pet is not in disorder, the skin of the pet may be scalded or burned by hot air blown by the blower, so that the pet is not only injured, but also very puzzled to the pet owner.

The semi-closed pet blow-drying box comprises a shell and an inner barrel firmly arranged in the shell, wherein an air inlet and a pet inlet are formed in one end wall surface of the shell, an openable fence is arranged at the other end opposite to the air inlet, a plurality of air holes are uniformly arranged in the peripheral wall of the inner barrel, and the inner space of the inner barrel is used for accommodating pets.
Further, the wind holes on the inner cylinder are arranged in a staggered mode.
Further, 1-2 air inlets are arranged.
Further, the shell is made of metal or plastic, and the inner cylinder is made of plastic or stainless steel.

Detailed Description
The following detailed description and illustrations of specific embodiments of the present invention will be made with reference to the accompanying drawings.
The semi-closed pet blow-drying box comprises a shell 1 and an inner barrel 4 firmly arranged in the shell 1, wherein an air inlet 2 and a pet inlet 6 are arranged on one end wall surface of the shell 1, an openable fence 5 is arranged on the other end opposite to the air inlet, a plurality of air holes 3 are uniformly arranged on the peripheral wall of the inner barrel 4, and the inner space of the inner barrel 4 is used for accommodating pets. The number of the air inlets 2 can be 1-2. The air inlet 2 is matched with the air inlet of the blower. The blower is inserted into the corresponding air inlet 2 to blow hot air into the outer shell 1, and the hot air is blown onto the body of the pet through the air holes 3 on the inner cylinder 1 in a uniformly dispersed manner.
Moreover, the wind holes on the inner cylinder are arranged in a staggered way.
The material of the outer shell can be metal or plastic, and the material of the inner cylinder can be plastic or stainless steel.
The modeling of the blow-drying efficiency and the detailed design of the device of the semi-closed pet blow-drying box are described below.
In order to make the blown wind more comprehensive and efficient to cover the whole body of the pet, scientific design and arrangement of the wind holes are required. In the semi-closed pet blow-drying box, the air holes are arranged in a staggered mode, so that the maximum blowing coverage surface and the highest wind intensity in unit area are used as targets, and the arrangement and design scheme of the air holes are calculated.
The modeling and analysis process of the blow-drying modeling efficiency is as follows.
1. Problem assumption and simplification
(1) Under ideal conditions, the pressure intensity in the ventilation space is equal everywhere, and the air quantity and the air speed blown out by each air hole are also the same;
(2) Assume that the wind hole is 10mm from the pet skin surface;
(3) If the air speed blown in from the air inlet is fixed, the blown hot air is equally divided by all the air holes and then blown out.
2. Problem analysis
One air hole corresponds to a coverage area, the size of the area is influenced by the diameter of the air hole, the larger the diameter is, the larger the coverage area is, the more air quantity blown out by each air hole is, but the air strength of the unit area possibly is reduced. Meanwhile, as the diameter of the wind hole and the coverage surface are increased, the gap between one coverage surface and the adjacent coverage surface is increased, so that the coverage area of the whole wind is reduced.
For aspect calculation, the maximum wind intensity of the global average unit area is taken as a target, and the corresponding number and radius of the wind holes are obtained, so that the arrangement and design scheme of the wind holes are obtained.
3. Establishing an analysis model of the number and the aperture of the wind holes
FIG. 2 shows a microscopic view of the wind direction of the wind hole.
In general, blowing through air holes of different apertures covers areas of different sizes behind the air holes. For example, for a typical air hole diameter of 0.1-0.5 cm, the coverage angle α of a household blower (power of about 1600W) after blowing out is about 17 degrees, and the effective blowing distance h is about 10 cm.
(1) Calculation model for diameter of coverage surface of air hole blowing
The calculation formula of the coverage diameter of the wind hole blowing is as follows:
d=2h×tanα+d (formula 1)
Wherein D is the diameter of the air hole, h is the efficient blowing distance, alpha is the covering angle after blowing out the air, and D is the covering surface diameter of the air hole for blowing out the air.
(2) Wind hole number and aperture relation calculation model
In order to ensure that the blown air can cover a larger area, adjacent air holes on the inner cylinder are staggered, and when warm air is blown out from each air hole, the formed coverage surfaces are arranged as shown in fig. 3.
The wind hole covers are represented as n rows and m columns, and a schematic diagram of each column is shown in fig. 4.
Setting the radius of the coverage surface of the air hole for blowing as r, wherein p is the air quantity introduced per second into the ventilation space; the length of the cylindrical expansion surface of the inner cylinder is N, and the width is M. From measurements by similar devices, the radius of coverage is approximately between 6mm and 10mm, and for the range of m, n, estimates are made:
wherein y represents the wind intensity of the whole unit area, P n Represents the wind intensity of a single wind hole, S represents the area of a cylindrical expansion surface,in order to divide n by 2, the design and arrangement scheme of the wind holes can be obtained after programming solution.
The model of the wind hole number and pore size analysis is given above. For different condition designs, the simulation calculation is performed by adopting a computer according to the model, and different results are obtained.
And (3) verifying an example:
for example, to demonstrate the solution of the model, the calculation is performed here in a case after determination M, N, P, with corresponding results. Assuming that m=600 mm, n=400 mm, p=2000, equation 3 becomes:
the objective function is unchanged and is consistent with equation 2.
According to the description and the explanation, the semi-closed pet blow-drying box disclosed by the invention uniformly blows air to pets through the plurality of air holes uniformly distributed on the inner cylinder to form proper temperature, wind force and wind direction, and warm air is uniformly and dispersedly blown to the whole body of the pets. Not only reduces noise pollution and potential noise injury to the pet, but also avoids scalding or burning the pet. In addition, a large number of wind holes are formed, so that energy is concentrated on the surface of the pet, the wind energy utilization rate is high, the drying efficiency is improved, and the time required for drying the hair of the pet is reduced. In addition, this pet weathers case convenient to use, easy operation.
In summary, the semi-enclosed pet blow-drying box of the invention has the following remarkable progress:
1. the pet is placed in the relatively closed space of the inner cylinder, so that the movement of the pet is limited, good air mobility is ensured, and the pet is easy to accept;
2. the design is scientific, the blowing is uniform, the energy is concentrated on the surface of the pet, the wind energy utilization rate is high, and the blowing efficiency is higher;
3. the blow-drying box is sealed relatively, and has certain reducing and inhibiting effects on noise of the blower;
4. the hot air blows to the pet after passing through the blow-drying box, so that the temperature is reduced to a certain extent, and the burn on the surface of the pet is reduced.
The foregoing is merely a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto. Those skilled in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept disclosed by the invention, and the obtained technical scheme is covered in the protection scope of the invention.
