The present invention relates to a nozzle of a vacuum device (VACUUM APPARATUS) designed to efficiently remove foreign substances generated in daily life. In more detail, the nozzle of the vacuum device according to the present invention is optimally designed to efficiently remove contaminated air and foreign substances generated in a specific space during welding or nail care, thereby exhibiting excellent performance and reducing maintenance costs.

In general, the air cleaning device is a device that performs the function of sucking the polluted air in the room and discharging it to the outside and supplying the purified air to the room. Conventionally, a specific area used in connection with a stand type air purifier or a large air purifier is used. It has been produced by an air purifier or the like. However, the air cleaner according to the prior art as described above has the disadvantage that the device itself is considerably large or the design of the nozzle portion is incorrectly hinders the flow and the pressure loss is large so that the performance is degraded.

The present invention has been devised to solve the above problems of the prior art, and provides a vacuum nozzle (NOZZLE) designed with an optimal air flow path so as to purify contaminated air and foreign substances very efficiently to secure a comfortable indoor space. There is a technical problem to be done.

Nozzle of the vacuum apparatus (VACUUM APPARATUS) according to the present invention for realizing the above technical problem is characterized in that the nozzle portion of the air disperser portion for dispersing the inhaled air, the inlet portion to which contaminated air or foreign matter is introduced It is done.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Nozzle of the vacuum apparatus (VACUUM APPARATUS) according to the present invention is the suction unit (1), the fan motor (2) disposed inside the suction unit, the suction air is introduced into the contaminated air or foreign matter as shown in Figure 1 to The air disperser 3 for dispersing air, the nozzle contraction portion 4 installed at a predetermined interval apart from the air disperser 3, and the clean air is discharged to the outside of the nozzle of the vacuum cleaner. It consists of a cover (5) and the like to play a role.

As shown in FIG. 1, the suction part 1 is connected to the nozzle contraction part 4 of one end of the air disperser and the other end thereof is connected to the nozzle contraction part 4 of the air disperser part and guides the flow of contaminated air or foreign matter. It is designed as. The suction guide is designed to maximize the air inflow rate, and the radius of curvature R of the suction shape should be in the range 112mm to 132mm. In addition, the fan motor (2) and the lighting device (6) is disposed inside the suction unit (1) so as to suck in foreign matter and brightly illuminate a specific area, and such a lighting device (6) only needs to be mounted inside the suction unit. The mounting position and type are not limited.

The air disperser 3 is designed to disperse the inhaled air to reduce the flow rate and increase the air pressure. In addition, one end of the nozzle contraction portion 4 serves as the outlet of the inlet and the other end corresponds to the outlet of the contaminated air, and is manufactured in a shape that minimizes the pressure loss of the flow and is spaced apart from the air disperser 3 at a predetermined interval. Furnace is installed outside the spreader.

As shown in FIG. 2, the suction part 1 is a part of the nozzle of the vacuum device, and the area ratio of the suction part inlet part 7 and the suction part outlet part 8 is designed to have a range of 0.9 to 1.3: 1. It was. It ranges from 0.25 to 0.65 times the inlet diameter. The shape of the suction guide is designed to increase the air inflow rate, and the radius of curvature R of the suction shape should be in the range of 112mm to 132mm. In addition, the fan motor 2 is disposed inside the suction unit 1 to operate as a power source for suctioning contaminated air, and a lighting device (not shown) may be mounted inside the suction unit to brighten a predetermined area. The lighting device only needs to be mounted inside the suction unit, and the mounting position or type thereof is not limited.

The design was performed by selecting from. In addition, the length between the nozzle shrinkage inlet 10 and the shrinkage outlet 11 was selected within the range of 0.7 times to 1.2 times the shrinkage inlet to perform the design.

The nozzle shrinkage inlet shape 12 and the shrinkage outlet shape 13 consist of two tertiary curves, and the two curved connection points 14 are at the nozzle shrinkage inlet 10 at the shrinkage outlet 11. It can be seen that as the direction is increased (as the junction point position increases) the likelihood of flow separation at the nozzle shrinkage inlet decreases, but the nonuniformity of the flow rate distribution at the nozzle shrinkage outlet 11 increases. Therefore, the optimum connection point was selected to obtain a high uniformity (outlet flow) flow without any flow separation. The curve formula by the method of designing the axisymmetric nozzle contraction part of MOORL is expressed as follows.

The axisymmetric nozzle shrinkage shape function Y ( x ) can be obtained by substituting the connection point dimensionless position X, the nozzle shrinkage length L, the nozzle shrinkage inlet diameter D ₁ , the nozzle shrinkage outlet exit diameter D ₂ , and the like. Therefore, the coordinates of the axisymmetric nozzle shrinkage by substituting the shrinkage ratio were obtained from the nozzle shrinkage shape coordinates Y ( x ) and -Y ( x ) from the nozzle shrinkage inlet 10 to the nozzle shrinkage outlet 11. The nozzle shrinkage shape data was applied to the nozzle of the present invention to have an optimum nozzle shape.
