Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as Figure 1-3 As shown, a fan device includes a casing 1 and a base 3 for supporting the casing 1 , and also includes a support rod for increasing the strength of the casing 1 . The support rods include an inner support rod 7 and an outer support rod 5 . The casing 1 is provided with an impeller 8 , and the central axis of the inner support rod 7 is parallel to the central axis of the impeller 8 . The casing 1 includes an air outlet 2 and an air inlet. The central axes of the air outlet 2 and the air inlet are perpendicular to each other, and the outer support rod 5 is arranged at the air inlet.

[0025] The inner support rod 7 can effectively resist the positive pressure on the casing 1 formed by the airflow flowing out of the air outlet 2, thereby preventing the casing 1 from expanding outward; the outer support rod 5 is It ...

Abstract

The invention discloses fan equipment. The fan equipment comprises a casing, a base for supporting the casing, and supporting rods for enhancing the strength of the casing, wherein the supporting rods comprise inner supporting rods and outer supporting rods; a vane wheel is arranged in the casing; the central axis of each of the inner supporting rod is parallel to the central axis of the vane wheel; the casing comprises an air outlet and an air inlet; the central axis of the air outlet is perpendicular to the central axis of the air inlet; the outer supporting rods are arranged at the air inlet. The fan equipment disclosed by the invention has the benefits that through the inner supporting rods, the effect of positive pressure formed by the air flow flowing out of the air outlet on the casing can be effectively resisted, so that the casing can be prevented from expanding outwards; the outer supporting rods can effectively resist the effect of the positive pressure on the casing when the air flow is sucked in from the air inlet, so that the casing can be effectively prevented from denting inwards. Through the design of the fan equipment, the casing can be effectively prevented from deforming, so that the service life of the fan equipment is prolonged.

Description

technical field [0001] The invention relates to the field of fan equipment, in particular to a fan equipment. Background technique [0002] When the air outlet of the fan equipment sucks in the air flow, a positive pressure is formed in the casing of the fan equipment, and due to the positive pressure, the casing is easily deformed to expand outward. When the airflow is inhaled from the air inlet, negative pressure is easily formed in the casing of the fan equipment, and due to the negative pressure, the casing is easily deformed inwardly. Due to the deformation of the casing of the fan equipment, the normal operation of the impeller in the fan equipment has been damaged. [0003] It can be seen that how to design a fan device capable of resisting the effect of external pressure on the casing and reducing the degree of deformation of the casing is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In order to solve the above pr...
