Abstract

The utility model discloses an air transferring device with an adjustable air transferring mouth, which comprises a casing, and a motor and a fan which are respectively arranged in the casing, wherein the casing is provided with a first air transferring mouth and a secondary air transferring mouth for transferring the outside air, and an air passing path for exhausting the air in the casing; particularly, an adjustable device which controls the secondary air transferring mouth to be opened and closed is installed at the secondary air transferring mouth; the adjustable device is provided with a rotary disk which is attached to the secondary air transferring mouth and can rotate corresponding to the secondary air transferring mouth; a plurality of air leak holes are arranged on the rotary disk; the rotary disk rotates to the air leak holes to be communicated with each second air transferring mouth to be matched with the rotation of the fan to drive the airflow to transfer into the casing from the first air transferring mouth and the secondary air transferring mouth, and the airflow are exhausted by the air passing path. In addition, the secondary air transferring mouth is sealed by the rotation of the rotary disk, so the airflow can be driven to be transferred into the casing from the air passing path and is exhausted by the first air transferring mouth.

Description

Can adjust the air delivery device of blowing mouth

Technical field

The utility model relates to a kind of air delivery device with two blowing mouths, particularly relate to a kind of regulating device that provides can close a blowing mouth when the exhaust, make the exhaust attraction force that motor running produced improve, make the inflatable object air delivery device of the blowing mouth adjusted of exhaust fast and can reach.

Background technique

Inflatable product be owing to can inflate whenever and wherever possible for using, and also can make things convenient for folding in order to collection after disappointing, so inflatable product is day by day diversified.Relatively, the gas transmission equipment that provides inflatable product to fill, exit required also becomes relevant dealer's research and development emphasis.As shown in Figure 1, gas transmission equipment 1 had a casing 11, usually and was arranged at the fan 13 that motors 12, in the casing 11 have bilateral flabellum 131,132 and can be subjected to motor 12 transmissions in the past, and a capping 14 that can cover casing 11.Be formed with a plurality of first blowing mouths 111 on casing 11 1 end faces, casing 11 sides are provided with a switch 112, turn round in order to the keying of controlling motor 12, and casing 11 also define an air outlet 15 jointly with capping 14 combination backs.In addition, also be formed with a plurality of second blowing mouths 141 in the capping 14.

When desire during to an inflatable product gas transmission, system butts up against the air outlet 15 of gas transmission equipment 1 at the air intake valve (not shown) place of inflatable product, utilize motor 12 to drive fan 13 runnings, import in casings 11 by first and second blowing mouth 111,141 with the attraction ambient air, and then under biparting leaf 131,132 guidings, export in the inflatable object (not shown) by air outlet 15.When desiring again to make the inflatable product exhaust, then be to make first blowing mouth 111 butt up against the air intake valve place of inflatable product, discharge outside the casing 11 by air outlet 15 via first blowing mouth 111 to attract the gas in the inflatable object by fan 13 runnings.

Because charger 2 had first and second blowing mouth 111,141 in the past, when exhaust operated, extraneous air-flow also can be inhaled in the casing 11 under fan 13 rotating suctions simultaneously, and then produced the flow-disturbing phenomenon in casing 11, caused exhaust efficiency not good.

Summary of the invention

A purpose of the present utility model is to provide a kind of can control the blowing mouth size, the exhaust attraction force that is produced with in good time lifting motor running, and make the inflatable object air delivery device of the blowing mouth adjusted of exhaust fast.

Of the present utility model being characterised in that: described housing is equipped with one in the described second blowing mouth place can be in order to control the regulating device that described second blowing mouth opens and closes, described regulating device has one and pastes the rotating disk touch in the described second blowing mouth place and can the rotation of the described relatively second blowing mouth place, on the described rotating disk and be provided with a plurality of bleeder ports, borrowing described rotating disk to rotate to described bleeder port is connected with each described second blowing mouth, cooperate described fan rotation to import in the described housing by described first and second blowing mouth to drive air-flow, and by described air vent output; Borrow in addition described rotating disk to rotate to described bleeder port and no longer be communicated with, import in the described housing by described air vent and can drive air-flow when making the fan rotation, and then export by described first blowing mouth with each described second blowing mouth.
