Embodiment Construction

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly disposed on the other element or there may be an intervening element. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "affixed to" another element, it can be ...

Abstract

The invention relates to an air suction pump, which includes a pump casing, a centrifugal fan blade, an axial flow fan blade and a rotating shaft. Both the centrifugal fan blade and the axial flow fan blade are arranged in the pump casing. The area where the fan blades are located is connected and communicated with a ventilation pipe, and the rotating shaft is respectively limited to the centrifugal fan blade and the axial flow fan blade in the circumferential direction, so that the rotating shaft can drive the centrifugal fan blade and the axial flow fan blade to rotate relative to the pump casing at the same time , wherein the exhaust volume of the centrifugal fan blade is greater than that of the axial flow fan blade. The present invention can improve the suction and displacement of the air pump as a whole, so as to meet the demand for large displacement; at the same time, the air pump arranges both the axial flow fan blade and the centrifugal fan blade in the pump casing, which can reduce the volume, and further The miniaturization of the whole structure of the air pump is realized to further meet the use requirement of the air pump assembled in the equipment.

Description

technical field [0001] The invention relates to the technical field related to flow control, in particular to an air suction pump. Background technique [0002] At present, a centrifugal fan blade is usually arranged in the pump casing of the existing air pump, so that when the air suction pump is working, the suction and exhaust function of the air suction pump is realized by specifically utilizing the flow guide of the gas when the centrifugal fan blade rotates. However, the air pump with the above-mentioned structure has a small exhaust volume during operation, which cannot meet the high demand for exhaust volume in equipment such as a steam oven. Contents of the invention [0003] In view of this, it is necessary to provide an air suction pump for solving the above technical problems. [0004] An air suction pump, comprising a pump casing, a centrifugal fan blade, an axial flow fan blade and a rotating shaft, the centrifugal fan blade and the axial flow fan blade are ...
