Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Following instance
For illustrating the present invention, but it is not limited to the scope of the present invention.
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected;Can
To be mechanical connection or electrical connection;Can be joined directly together, can also be indirectly connected to by intermediary, Ke Yishi
The connection of two element internals." first " " second " " the 3rd " " the 4th " does not represent any sequence relation, merely for convenience
The differentiation carried out is described.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood in the present invention
In concrete meaning.At the time of " current " is when certain action is performed, occur multiple current in text, be real in being passed with the time
Shi Jilu.
Due to existing issue, the present invention gives smoke machine Tobacco Control system and cigarette machine.
Product, method etc. will be described in detail by basic engineering, extension design and alternative design below.
A kind of oil smoke flow guiding structure applied to two fans range hood, as in Figure 3-5, it is structure as a whole, and it is wrapped
Include:Snail tongue 1, deflector 2;Snail tongue 1 is in the first end of the axial direction of deflector 2;Snail tongue 1 sets the first spiral case installation position;Deflector 2
Second spiral case installation position is set;Deflector 2 includes:First blower fan deflector 21 and the second blower fan deflector 22;First blower fan is led
It is curved slab to flow plate 21, the second blower fan deflector 22, and the first blower fan deflector 21 and the second blower fan deflector 22 are disposed opposite to each other,
And the exhausting plate end of the two intersects to form " people " font.
It referring herein to integrative-structure, can be processed, be more convenient using the machining accuracy of moulding using plastic injection
Control the more accurate of snail tongue 1.The structure of moulding is stronger with respect to stability for aluminum-pinch.
The herringbone structure of deflector 2 is that two fans fume-exhausting, oil smoke can be from respective wind in order to which correspondence two fans are set
The position of machine is moved up, and lambdoid first blower fan deflector 21, the second blower fan deflector 22 are respectively intended to drainage correspondence blower fan
Oil smoke.
The plate that curved slab can change for arc or each position radian.Lambdoid junction leads to upper snail
The air outlet of shell 5, i.e. herringbone deflector 2 lead to oil smoke by arc drainage the air outlet of upper volute 5.
Because snail tongue 1 is " u "-shaped structure, centre is crossbeam, and both sides are two side tongues, therefore, on the one hand in order to increase snail
Tongue 1 by force intensity, and be easily installed between spiral case, the side tongue at the two ends of snail tongue 1 multiple first ribs 13, first be set
Multiple first mounting holes 14 are set on ribs 13, and all first mounting holes 14 constitute the first spiral case installation position, pass through the first snail
Shell installation position is installed in spiral case.
It should be noted that the width of the first ribs 13, shape do not do excessive limitation, as long as playing reinforcement and setting peace
The effect for filling position is all to meet design principle and protection domain.
Similarly, in order to increase the structural stability of deflector 2 and by force intensity, while facilitating cigarette power traction flow structure to be installed to
In spiral case, the inner side of deflector 2, between the first blower fan deflector 21 and the second blower fan deflector 22 set more than one second
Multiple second mounting holes 24 are set on ribs 23, the second ribs 23, and all second mounting holes 24 constitute the second spiral case and installed
Position.
It should be noted that similar to the first ribs 13, the width of the second ribs 23, shape do not do excessive limitation,
As long as it is all to meet design principle and protection domain to reach its respective action.
When specific to deflector 2 and the position relationship of snail tongue 1, the second end of the axial direction of deflector 2 is connected in snail tongue 1
Between plate middle part.Because deflector 2 is lambdoid stereochemical structure, the ridge of Chinese outdated building is analogous to.And snail tongue 1 is set
In ridge two ends, but ridge is connected with the middle part of the intermediate plate of snail tongue 1 in this technique.
In order to form uniform, symmetrical water conservancy diversion effect, the first blower fan deflector 21, the second blower fan deflector 22 in shape and
Size all same.
On the other hand, deflector 2 and the symmetry axis of snail tongue 1 coincide.Symmetrical structure is integrally formed, to adapt to two fans
Symmetrical structure.
After being installed on two fans range hood, the plane of symmetry of spiral case and oil smoke drainage knot in two fans range hood
The plane of symmetry of structure is overlapped.
In addition, in order to further increase the stability that oil smoke flow guiding structure is connected with spiral case, oil smoke flow guiding structure also includes
Side wall 3, side wall 3 is in the second end of the axial direction of deflector 2, and side wall 3 is integrated processing structure with deflector 2, snail tongue 1.
In order to increase the structural stability of side wall 3, while be conveniently installed on spiral case, side wall 3 is back to the side of deflector 2
Set and multiple 3rd mounting holes 34 are set on multiple 3rd ribs 33, the 3rd ribs 33.
Ibid, the number of the 3rd ribs 33, size, shape do not make excessive limitation, as long as corresponding work can be reached
With, preferably design number be, it is considered to symmetrical structure form.
For symmetrical, symmetry axis of the side wall 3 perpendicular to deflector 2;Side wall 3 is by the sub- sub- wall 32 in the side of wall 31 and second in the first side
Composition, the sub- sub- wall 32 in the side of wall 31 and second in the first side is symmetrical with the symmetry axis of deflector 2.The sub- wall 31 in first side is from the first wind
The exhausting plate end of machine deflector 21 extends to the outside of deflector 2, air-out of the sub- wall 32 in the second side from the second blower fan deflector 22
Plate end extends to the outside of deflector 2;
The plane of symmetry of the curved surface of side wall 3 and the plane of symmetry of deflector 2 coincide.
Present invention also offers a kind of two fans range hood, as shown in figs 6-8, it includes spiral case and applied to two fans
The oil smoke flow guiding structure of range hood;Oil smoke flow guiding structure is arranged in spiral case, and deflector 2 is in the middle part of spiral case, deflector 2
The first blower fan deflector 21 on the oil smoke discharge path of the first sub- spiral case of spiral case, the second blower fan deflector of deflector 2
22 on the oil smoke discharge path of the second sub- spiral case of spiral case.
Wherein, spiral case is made up of upper volute 5 and lower spiral case 4, and upper volute 5 is provided with spiral case air outlet 51;Lower spiral case 4 is provided with snail
Shell air inlet 41, the lower middle of spiral case 4 sets horizontal mounting surface 43, and oil smoke flow guiding structure is installed on horizontal mounting surface 43, led
Stream plate 2 is connected by the first spiral case installation position with being horizontally mounted position, and the snail tongue 1 and side wall 3 of oil smoke flow guiding structure are respectively by the
One spiral case installation position, the 3rd mounting hole 34 are connected with upper volute side wall 42, lower snail shell side wall 52.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
