Problems solved by technology

However, this air pump, which has been popularized in Germany for decades, has serious flaws according to its design. It only uses half of its power to generate positive and negative pressures (positive air out, negative air inhale), and its efficiency is only about 50%. Not even less than half the power and price in vain

Embodiment 1

[0019] See attached figure 1 , figure 2 , Embodiment 1: The embodiment of the present invention provides a high-pressure vortex air pump, which includes a motor 1, a pump casing 2, an impeller 3, a cover 4, an air inlet pipe 5, an air outlet pipe 6, and a chassis 7.

[0020] The motor 1 and the pump casing 2 are concentrically fixed, the output shaft of the motor 1 is concentric with the impeller 3 and fixed with a key, the shaft center of the cover 4 is fitted with a bearing sleeve to connect the motor 1 output shaft end to fix the cover 4, and there is an air intake pipe 5 under the pump casing 2 , leading to one side of the blade 8 on the impeller 3 in the shell cavity.

[0021] There is an air outlet pipe 6 connected to it under the cover 4, and there is a smooth arc-connected isolation block 9, which can dynamically isolate the air intake and air outlet with micro-slits (when the impeller 3 rotates) to prevent short-circuiting of the two gases.

[0022] The air inlet p...

Embodiment 2

[0028] Example 2: see image 3 Figure 4 , except that the air outlet pipe 6 and the corresponding smooth and smooth arc connecting spacer 9 become curved except that the smooth concave arc spacer 12 bends, all the other principles remain unchanged. Its advantage is stronger than that of embodiment 1, because the isolation block shortens into a fraction, the weekly blade 8 action time is long, and the blank period is reduced, so the air pressure and output power are just stronger. And the front and rear ends of the air pipe are placed coaxially and in line with the installation direction. Air intake pipe 5 is also the same as before, and directly enters the intake air reserve cavity 11 . Smooth concave arc isolation block 12 image 3 The middle image is concentric with the pipe hole and shrinks the circular segment shape, which should actually be the same size as the tube hole, and it should be connected to the outside of the gap, and the gap is connected to the duct c (sma...

Abstract

The invention discloses a high-pressure vortex air pump. The high-pressure vortex air pump comprises a motor, a pump case, an impeller, a cover, an air inlet pipe, an air outlet pipe and a base plate,wherein each blade is in a bevel and big arc shape; according to the cross section defined by the cover, the circumferential vertical surface of a boss, the blades and the inner circle of the pump case, a high-pressure air outlet is formed from the big cross section of an air inlet to the small cross section of an air outlet, and the tops of the blades are in micro-seam connection with the innercircle of the pump case to cause high-pressure air inlet and outlet, and positive and negative air pressure is twice or more higher than that of a traditional air pump can be formed. Moreover, the cost is the same.

Description

technical field [0001] The invention relates to a blower, in particular to a vortex blower or a vortex air pump. Background technique [0002] Because the blower with the common name of blower is a variety that lacks air pressure seriously, it will not be discussed here, but if it is used for a cheap blower that requires blowing and suction pressure, people usually buy a vortex air pump because its air pressure is the same as the power. It is about seven times larger than ordinary blowers. However, this air pump, which has been popularized in Germany for decades, has serious flaws according to its design. It only uses half of its power to generate positive and negative pressures (positive air out, negative air inhale), and its efficiency is only about 50%. Not even less than half the power and price in vain. Contents of the invention [0003] The purpose of the present invention is to provide a high-pressure vortex air pump for the serious defects of the prior art, so th...
