Nozzle

Abstract

The utility model discloses a nozzle which comprises an air inlet pipe, an outer cover is arranged at one end of the air inlet pipe, and the outer cover covers the air outlet end of the air inlet pipe and is connected with the air inlet pipe through the outer cover, so that an air inlet area is formed at the joint of the air inlet pipe and the outer cover; in conclusion, when airflow flows in from one end of the air inlet pipe and flows out from the other end of the air inlet pipe, the flowing airflow siphons air in the air inlet area, and therefore the nozzle can spray larger airflow. On the basis, the structure of the nozzle is optimized, so that the energy consumption is lower while the same amount of air is sprayed by the nozzle.

Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, and particularly relates to a nozzle. Background Art

[0002] The existing air flow nozzles are usually round tubular. The air flow ejected from the nozzle directly contacts the external air flow of the nozzle, resulting in the non-concentration of the air flow ejected from the nozzle, and the air flow velocity and flow rate are small. Content of the Utility Model

[0003] The purpose of the utility model is to provide a nozzle to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a nozzle, including an air inlet pipe, one end of the air inlet pipe is provided with an outer cover; the outer cover covers the air outlet end of the air inlet pipe, so that an air inlet area is formed at the connection between the air inlet pipe and the outer cover.

[0005] As a preferred technical solution of the utility model: one end inside the air inlet pipe is provided with a drainage area, and the drainage area is connected and communicated with a narrow throat provided, and the narrow throat is provided with a flared opening at the end far away from the drainage area.

[0006] As a preferred technical solution of the utility model: the outer cover is connected with the air inlet pipe through a provided connecting piece.

[0007] As a preferred technical solution of the utility model: the number of the connecting pieces is multiple, and they are equally spaced and arrayed on the outer cover.

[0008] Adopting the above technical solution, the beneficial effect of the utility model is: when the air flow flows in from one end of the air inlet pipe and then flows out from the other end of the air inlet pipe, the flowing air flow siphons the air in the air inlet area, so that the nozzle can eject a larger air flow. Based on this, the utility model optimizes the structure of the nozzle, so that the nozzle consumes less energy while ejecting the same amount of air. Description of the Drawings

[0013] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0014] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a nozzle, including an air inlet pipe 1, and an outer cover 3 is provided at one end of the air inlet pipe 1; by covering the outer cover 3 on the air outlet end of the air inlet pipe 1, an air inlet area 2 is formed at the connection between the air inlet pipe 1 and the outer cover 3.

[0015] In summary, when the air flow flows in from one end of the air inlet pipe 1 and then flows out from the other end of the air inlet pipe 1, the flowing air flow siphons the air in the air inlet area 2, so that the nozzle can eject a larger air flow. Based on this, the present utility model optimizes the structure of the nozzle, so that the nozzle consumes less energy while ejecting the same amount of air.

[0016] Furthermore, since a drainage area 5 is provided at one end inside the air inlet pipe 1, and the drainage area 5 is connected and communicated with a narrow throat 6 provided, and a flared opening 7 is provided at the end of the narrow throat 6 away from the drainage area 5, therefore, by using the above structure, the flow rate of the air flow is enhanced after flowing through the entire air inlet pipe 1, and then the flow rate of the air flow is increased. When the flow rate increases, the gas at the air inlet area 2 is siphoned, so that the two air flows are combined to enhance the air ejection amount of the device.

[0017] On the basis of the above solution, since the outer cover 3 is connected to the air inlet pipe 1 through a provided connecting member 4, therefore, the outer cover 3 can be reliably connected to the air inlet pipe 1.

[0018] Furthermore, the number of the connecting members 4 is multiple and is arranged in an equidistant array on the outer cover 3. Among them, the number of the connecting members 4 is preferably four. Therefore, while ensuring the reliable connection between the outer cover 3 and the air inlet pipe 1, the blocking of the air flow by the connecting members 4 is reduced.

[0019] In summary, the nozzle has the advantages of simple structure, small volume and convenient installation. By comparing with the nozzle without the outer cover 3, since the outer cover 3 is installed outside the nozzle and the internal structures of the outer cover 3 and the intake pipe 1 cooperate with each other, the gas injection volume of the nozzle is further improved. Under the condition of the same gas injection volume, the nozzle with the outer cover 3 can reduce the ejected volume of compressed air, and the saved gas volume is about 40%.

[0020] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
