Detailed Description
The invention is further illustrated by the following figures and examples.
When the servo electric driver is used, the fan runs, the first elastic sheet deforms under the blowing of the fan to enable the first through hole to ventilate, negative pressure is generated inside the shell along with the outward flowing of air inside the shell, and the second elastic sheet deforms, so that a gap is generated between the second elastic sheet and the supporting column to enable external air to enter the shell, air flow is formed, and heat in the shell of the servo motor is taken away in the flowing process of the air; when the power-off, the fan stop operation, first flexure strip is because of losing blowing of fan and the original state of recovering covers first through-hole, and the second flexure strip makes the second flexure strip paste tight support column in the resilient force effect reconversion for outside air can not get into in the casing, prevents like this that outside dust or steam etc. from diffusing in to the casing.
As a preferred embodiment, referring to fig. 2, the supporting pillar is configured such that the diameter of one end is larger than that of the other end, a protruding portion 8 protruding outward is circumferentially disposed between two ends of the supporting pillar, the protruding portion may be formed in a spherical shape or a circular ring shape as shown in fig. 2, the second elastic sheet is located between the end of the supporting pillar with the larger diameter and the protruding portion, when the fan is in operation, the second elastic sheet slides along the protruding portion after being deformed, so that a gap is formed between the second elastic sheet and the supporting pillar for air circulation, during this process, if a small water droplet enters the transition space and is subjected to a wind force, the small water droplet moves forward along the supporting pillar until the protruding portion and then moves forward over the protruding portion, and diffuses and evaporates due to a friction force during the process of turning over the protruding portion, and flows along with the air flow, and is not easy to stay in the casing, when the fan is, under the effect of elastic recovery power, the second flexure strip restores to the original state gradually, the second flexure strip at first laminates the bulge and makes gas can not exchange outside the casing at this in-process, continue the in-process of recovering at the second flexure strip like this and form the tensile force to the gas in the casing, thereby make gas form less negative pressure in the casing is inside, make first flexure strip and baffle laminating effect better like this, dustproof and waterproof effect is better, in the in-service use process, also can make the second flexure strip with the bulge laminating back continue shrink to with the outward flange laminating of bulge stop the shrink promptly so that gas forms less negative pressure in the casing. In this embodiment, the first elastic sheet is located on a side of the partition plate opposite to the fan, and the top end of the first elastic sheet is fixed on the partition plate; and the end with the larger diameter of the supporting column is fixed on the second heat radiator.
In order to further prevent dust from entering the casing, referring to fig. 2, an annular support body 11 is arranged on the second heat radiation body, and the edge of the second elastic sheet is fixed on the outer surface of the support body, so that the inner side of the support body forms the transition space; a filter screen 12 is arranged in the transition space, the edge of the filter screen is connected with the inner surface of the support body, and the filter screen is tightened when the filter screen is arranged; the filter screen is positioned at one end of the support body, which is far away from the second heat radiation body, and is in contact with the second elastic body; the structure can further filter external dust and the like when the fan operates, impact on the filter screen is formed under the action of the elastic force of the second elastic body after the fan stops operating, so that the dust is not favorable for being attached to the filter screen to form blockage, and of course, the support body can be further provided with a diversion pipeline or can be detachably connected with the second radiator and other structures so as to be convenient for removing the falling dust.
In order to further prevent dust from entering the casing, referring to fig. 3-6, a filter screen 13 may also be arranged in the casing, and the support body is located between the filter screen and the second heat dissipation body; the filter screens comprise a first filter screen 13-1 and a second filter screen 13-2, an elastic strip 14 is arranged between the first filter screen and the second filter screen, one end of the elastic strip is connected with the first filter screen, the other end of the elastic strip is connected with the second filter screen, the structure is influenced by wind force when the fan operates, the elastic strip deforms, and when the fan stops operating, the elastic strip drives the filter screens to swing back and forth after losing the effect of the wind force, so that dust is not beneficial to being attached to the filter screens to form blockage; as a variant, see fig. 7, a filter screen 13 is arranged in the casing, and the support body is located between the filter screen and the second heat sink; the both ends of filter screen are installed elasticity strip 14, during the installation with the elasticity strip at elasticity strip both ends fix on the upper and lower face of casing can.
