Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

As shown in fig. 1 and fig. 2, the present invention provides a powder delivery pump, including: the main part 1, be equipped with cavity 11 in the main part 1, be equipped with first interface 12, second interface 13, the third interface 14 that are equipped with mutually perpendicular respectively in the cavity 11, second interface 13 with the third interface 14 is on same straight line.

As shown in fig. 1 and 2, the first port 12 is connected to the powder pump barrel adaptor 2, and powder enters the cavity 11 from the first port 12, and in this embodiment, the first port 12 is located above the second port 13 and the third port 14.

As shown in fig. 1 and 2, the second port 13 is connected to the compression pipe 3, the compression pipe 3 is connected to compressed gas, and the compressed gas blows the powder falling from the first port 12 into the third port 14. The rate of compressed gas connected to the compression tube 3 and the pressure can be controlled while the rate of powder flow can be controlled so that the flow rate of the powder can be more uniform.

As shown in fig. 1 and 2, the third interface 14 is connected to a powder tube 4, and the powder tube 4 is connected to the third interface 14 through a gland 5. The outer surface of the powder tube 4 is arranged in a step shape, and is provided with a first step 41 and a second step 42 connected with the first step 41. The second step 42 extends into the main body 1 to be connected with the third interface 14, and the gland 5 is arranged outside the second step 42.
