Description

Technical Field

[0001] This utility model relates to a vortex air pump, and in particular to an inlet air structure for a vortex air pump, belonging to the field of air pump technology. Background Technology

[0002] The impeller of a vortex air pump consists of several blades, similar to the impeller of a large gas turbine. The air between the impeller blades is subjected to centrifugal force and moves towards the edge of the impeller. There, the air enters the pump body's annular cavity through the inlet and recirculates from the starting point of the blades in the same way. The circulating airflow generated by the impeller's rotation is output with extremely high energy from the outlet for use.

[0003] Existing vortex air pumps have both the air inlet and outlet located on the rear housing, meaning they are on the same side. When using a vortex air pump in an industrial vacuum cleaner, the front of the vacuum cleaner needs to be connected to the suction hose for easy gripping and dust collection, while the rear needs to be connected to the dust collection bin or garbage bag. If both the air inlet and outlet are located on the rear, the suction hose connected to the air inlet needs to go around half a circle to the front of the vacuum cleaner, which is inconvenient for users to pull the hose to move the vacuum cleaner. Furthermore, a bent suction hose can easily affect the air intake, thus affecting the suction effect. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a front air intake structure for a vortex air pump that can be used for both front and rear air intake to meet different needs and has better versatility.

[0005] The technical solution of the inlet air structure of the vortex air pump of this utility model is as follows: it includes a front cover and a rear cover, a pump chamber is formed between the front cover and the rear cover, an impeller is arranged in the pump chamber, a motor is arranged on the rear side of the rear cover, the output shaft of the motor is connected to the impeller, an inlet air port is opened in the front cover and communicates with the pump chamber, a rear outlet air port is opened in the rear cover and communicates with the pump chamber, and an outlet pipe is arranged on the rear outlet air port.

[0006] Furthermore, a rear air intake is provided in the rear housing, which corresponds to the front air intake of the front cover, and a sealing cover is provided on the rear air intake.

[0007] Furthermore, a connecting seat is provided on the front cover at the air inlet.

[0008] Furthermore, a fixing hole is provided on the connecting seat.

[0009] The beneficial effects of the inlet air structure of the vortex air pump of this utility model are: by opening an inlet air port on the front cover and retaining the original rear air port on the rear cover, people can block the rear air port and use the inlet air port to enter the air according to the needs of the application equipment or application scenario, or block the front air port and use the rear air port to enter the air port, thus meeting different needs and having better versatility.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0014] In the description of this utility model, unless otherwise explicitly specified and limited, terms such as "connection" and "fixation" should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] This utility model relates to the inlet air structure of a vortex air pump, such as... Figure 1 — Figure 3As shown, it includes a front cover 1 and a rear cover 2, with a pump chamber formed between the front cover 1 and the rear cover 2. An impeller is installed in the pump chamber. A motor 3 is installed on the rear side of the rear cover 2, and the output shaft of the motor 3 is connected to the impeller. An inlet 4 is opened in the front cover 1, which communicates with the pump chamber. A outlet 5 is opened in the rear cover 2, which communicates with the pump chamber. An outlet pipe 6 is installed on the outlet 5.

[0016] Furthermore, a rear air inlet 9 is provided in the rear housing 2, which corresponds to the front air inlet 4 of the front housing 1. A sealing cover 10 is provided on the rear air inlet 9. The rear air inlet 9 in the rear housing 2 is the original air inlet (i.e., the air inlet on the existing vortex air pump). During manufacturing, the structure of the rear air inlet on the original mold is not changed. If the front air inlet 4 is to be used, the rear air inlet 9 can be sealed by blocking it with the sealing cover 10. If the rear air inlet 9 is to be used, the sealing cover 10 of the rear air inlet 9 is opened, and the front air inlet 4 is blocked and sealed with the sealing cover. The front and rear air inlets can be switched as needed, which improves versatility.

[0017] Furthermore, a connecting seat 7 is provided on the front cover 1 at the air inlet 4. When the vortex air pump is used in an industrial vacuum cleaner, the suction pipe can be connected through the connecting seat 7.

[0018] Furthermore, a fixing hole 8 is provided on the connecting seat 7. A connecting plate can be provided at one end of the suction pipe. The shape of the connecting plate corresponds to that of the connecting seat 7, and the two are fixedly connected by fasteners passing through the fixing hole 8.

[0019] This utility model discloses an inlet air structure for a vortex air pump. The main feature is an inlet air port 4 in the front housing 1, while the original rear air port 9 of the rear housing 2 is retained. When this vortex air pump is used in specific equipment with front air intake and rear air exhaust (such as an industrial vacuum cleaner), the rear air port 9 can be sealed with a sealing cover 10. The inlet air port 4 can be connected to an air intake pipe (which can be the suction pipe of a vacuum cleaner), and the rear air outlet 5 is connected to an air outlet pipe 6. During operation, the impeller is rotated by the motor 3, and the air outlet is located in the hollow space between the impeller blades. The air is subjected to centrifugal force and moves towards the edge of the impeller. There, the air is drawn into the pump chamber through the inlet pipe and the front inlet 4, and then circulates again from the starting point of the blade in the same way. The circulating airflow generated by the rotation of the impeller is output with extremely high energy from the rear outlet 5 and the outlet pipe 6. If the rear inlet 9 is to be used for air intake, the sealing cover 10 of the rear inlet 9 can be removed and the front inlet 4 can be blocked through the sealing cover 10. People can replace the front or rear air intake as needed, which has good versatility and meets different needs.

[0020] The above specific embodiments are used to explain and illustrate the present utility model, and are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made to the present utility model within the spirit and protection scope of the claims shall fall within the protection scope of the present utility model.
