Abstract
The utility model relates to a handheld type blow-suck machine with an auxiliary air tube. The handheld type blow-suck machine with the auxiliary air tube comprises a machine head portion (1) and an air cylinder (2), wherein the air cylinder (2) comprises an air-suction tube (3) and an air-blow tube (4). The handheld type blow-suck machine with the auxiliary air tube is characterized in that the auxiliary air tube (9) is arranged in the front end portion of the air-blow tube (4) near an air outlet (8), and the auxiliary air tube (9) surrounds the air outlet (8) to form an auxiliary flow channel (10). The structure of the auxiliary flow channel has the feature of amplifying air and can be led by high-speed air flow to form air flow with higher speed, and therefore outlet air flow can be blown out after being amplified by the auxiliary flow channel. The flow channel capable of amplifying air flow and resisting turbulent flow is simple in structure, low in cost, effective and reliable, and applicable to most blow-suck machines in markets.

Summary of the invention
The purpose of this utility model is to provide a kind of blower of improved airflow path, to solve above-mentioned the deficiencies in the prior art.
The technical solution adopted in the utility model is as follows:
A kind of Handheld blowing sucking machine with auxiliary inflator comprises chain-drive section and air duct; Described air duct comprises wind sucting tube and Blowing drum; It is characterized in that: described Blowing drum is provided with auxiliary inflator near the leading section of air outlet, and described auxiliary inflator surrounds air outlet and forms the secondary flow road.
Described Handheld blowing sucking machine with secondary flow road, it is characterized in that: described wind sucting tube is provided with groove near the leading section of inlet scoop, be provided with sliding muscle on the described auxiliary inflator, sliding muscle is slidably mounted in the groove, thereby so that described auxiliary inflator regulate slidably with respect to the position of Blowing drum.
Described Handheld blowing sucking machine with secondary flow road is characterized in that: described auxiliary inflator can be locked at least two positions with respect to Blowing drum, when being locked in primary importance, is used for the suction mode of blower; When being locked in the second place, be used for the blowing mould formula of blower.
Described Handheld blowing sucking machine with secondary flow road is characterized in that: described auxiliary inflator is comprised of the first wall and the second wall, and described the first wall is the plane, and described the second wall is taper surface.
The utility model staggers by the air inlet port of wind sucting tube and the position, gas outlet of Blowing drum, has avoided the generation of eddy current, can effectively increase air blowing efficient; The structure in secondary flow road has the characteristic that air amplifies, and available high velocity air drainage reaches air-flow more at a high speed, thereby so that go out entraining air stream through blowing out again after its amplification; This runner air-flow amplification and turbulence are simple in structure, with low cost, and be effectively reliable, is applicable on the market most of blowers.

The specific embodiment
As shown in Figure 1, Handheld blowing sucking machine of the present utility model comprises chain-drive section 1 and air duct 2, and the inside of chain-drive section 1 is equipped with a motor and fan blade (not shown), and fan blade is installed on the motor output shaft, produces working air current by the rotation of driven by motor fan blade.Also be provided with a pressure-vaccum function-changing device (not shown) in the chain-drive section 1, be used for described blower is set in blowing mould formula or suction mode.
Described air duct 2 comprises wind sucting tube 3 and Blowing drum 4, described wind sucting tube 3 has an inlet scoop 5 and air outlet 6, described Blowing drum 4 has an air intake 7 and air outlet 8, leading section at Blowing drum 4 close air outlets 8 is provided with auxiliary inflator 9, and described auxiliary inflator 9 surrounds air outlet 8 and forms secondary flow roads 10.
Shown in Fig. 2,3,4, end wall in wind sucting tube 3 close inlet scoops 5 is provided with at least one groove 11, at auxiliary air duct 9 at least one sliding muscle 12 is set, described sliding muscle 12 is arranged on the lateral wall of auxiliary air duct 9, and described sliding muscle 12 is slidably mounted in the groove 11.
Adopt common mode, for example at groove 11 interior some locked points that arrange, sliding muscle 12 can be locked on the corresponding position, thereby auxiliary air duct 9 can be locked at required operating position, the utility model preferably can be with the locking position of described auxiliary air duct 9 at least two positions, when being locked in primary importance, be used for the suction mode of blower; When being locked in the second place, be used for the blowing mould formula of blower.
Shown in Fig. 3,4, auxiliary inflator 9 is comprised of the first wall 13 and the second wall 14, and described the first wall 13 is the plane, and described the second wall 14 is taper surface.
The course of work of the present utility model is as follows:
Shown in Fig. 1,5, when blower is operated in suction mode, auxiliary air duct 9 retractions, the dust mouth 15 of sending into the chain-drive section setting foreign material such as inlet scoop 5 suck air of wind sucting tube 3 and leaf, the inner flow passage by wind sucting tube 3 are pulverized the foreign material such as leaf through fan blade after is discharged to the collecting bag (not shown).
