Description

Turbine blower with controllable flow rate Technical Field

[0001] This utility model relates to the field of turbine dust blowers, and more particularly to a turbine dust blower with controllable flow rate. Background Technology

[0002] Turbine-type dust guns accelerate compressed air or ambient air through a high-speed rotating turbine impeller, creating a controllable airflow impact force to achieve cleaning operations. Therefore, dust guns are mainly used for dust removal in factories and during installation and maintenance. They are best suited for cleaning in narrow, high places and inside air pipes where they are not accessible by hand.

[0003] High-pressure gas blowing dust removal effect is poor and it is widely used in high-end manufacturing fields. However, the existing turbine dust gun is limited by its structure and cannot control the flow rate, which cannot meet the needs of precision cleaning and has low practicality. Summary of the Invention

[0004] In order to overcome the problems of existing turbine-type dust guns being limited by their structure, unable to control the flow rate, unable to meet the needs of precision cleaning, and having low practicality.

[0005] The technical solution of this utility model is as follows: a turbine-type dust blower with controllable flow rate, including an outer shell, a handle, an adapter, an air collection pipe, and an adjusting cap. A turbine fan is installed inside the outer shell. The left end of the outer shell is fixedly connected to the handle. An air outlet pipe is provided on the right end of the outer shell surface. The air outlet pipe is fixedly connected to the adapter. An air collection pipe is fixedly installed on the end of the adapter away from the air outlet pipe. An adjusting cap is installed on the end of the air collection pipe away from the adapter. A first air leakage hole and a second air leakage hole are respectively opened on both sides of the adapter surface. A sealing sleeve is movably installed on the outer side of the adapter.

[0006] Preferably, in the dust blowing operation, a high-pressure airflow is delivered by a turbine fan, and after passing through the air collection pipe, it is blown out from the regulating cap to achieve dust blowing. At the same time, the position of the sealing sleeve is adjusted to expose or close the first and second air leakage holes, thereby allowing air leakage during airflow delivery, reducing the overall airflow, achieving flow controllability, and improving practicality.

[0007] Preferably, a trigger button is provided on the inside of the handle, and a power supply box is installed at the lower end of the handle.

[0008] Preferably, the adapter is provided with a ventilation duct. One end of the ventilation duct is adapted to the air outlet pipe and has a rectangular structure design. The other end of the ventilation duct is adapted to the left end of the air collection pipe and has a circular structure design.

[0009] Preferably, a baffle is provided on the inner side of the right end of the air collection duct, and the surface of the baffle has through holes. A connecting slide rail is provided on the right end of the outer surface of the air collection duct.

[0010] Preferably, the regulating cap and the air collection pipe are slidably connected by a connecting slide rail, and an air outlet is opened on the right end face of the regulating cap, with the air outlet and the through hole corresponding one to one.

[0011] Preferably, the diameter of the first vent is smaller than the diameter of the second vent, and both the first and second vents are evenly spaced.

[0012] Preferably, the sealing sleeve consists of an arc-shaped seat one and an arc-shaped seat two. The surface of the arc-shaped seat one is provided with a through groove. Both ends of the arc-shaped seat one and the arc-shaped seat two are detachably connected by bolts. The length and width of the through groove are adapted to the air leakage hole one and the air leakage hole two.

[0013] The beneficial effects of this utility model are:

[0014] This flow-controlled turbine-type dust blower uses a turbine fan to increase high-pressure airflow, which is then blown out through a collection pipe to remove dust. As the airflow passes through the adapter, the operator can adjust the position of the sealing sleeve to expose the vent hole, thereby reducing the airflow through the vent hole and achieving flow control. At the same time, as the airflow is blown out, the position of the vent hole can be changed by rotating the adjusting cap, misaligning the vent hole and the through hole, changing the inner diameter of the vent hole, reducing the airflow, and improving practicality.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to Figures 1-5. This utility model provides an embodiment of a turbine-type dust blower with controllable flow rate, including a housing 1, a handle 2, an adapter 4, an air collection pipe 5, and an adjusting cap 6. A turbine fan is installed inside the housing 1. The left end of the housing 1 is fixedly connected to the handle 2. A trigger button is provided on the inner side of the handle 2. A power supply box 3 is installed at the lower end of the handle 2. An air outlet pipe is provided on the right end of the surface of the housing 1. The air outlet pipe is fixedly connected to the adapter 4. An air collection pipe is fixedly installed at the end of the adapter 4 away from the air outlet pipe. The end of the air collecting pipe 5 away from the adapter 4 is equipped with an adjusting cap 6. The two sides of the surface of the adapter 4 are respectively provided with a first air leakage hole 7 and a second air leakage hole 8. A sealing sleeve 9 is movably installed on the outer side of the adapter 4. During the dust blowing operation, the high-pressure airflow is delivered by the turbine fan and blown out from the adjusting cap 6 after passing through the air collecting pipe 5 to achieve dust blowing. At the same time, the position of the sealing sleeve 9 is adjusted to expose or close the first air leakage hole 7 and the second air leakage hole 8, thereby allowing air leakage during airflow, reducing the overall airflow, achieving flow controllability, and improving practicality.

[0023] Please refer to Figures 1, 4, and 5. In this embodiment, the adapter 4 is provided with a ventilation channel. One end of the ventilation channel is adapted to the air outlet pipe and has a rectangular structure. The other end of the ventilation channel is adapted to the left end of the air collecting pipe 5 and has a circular structure. A baffle 51 is provided on the inner side of the right end of the air collecting pipe 5. The surface of the baffle 51 has through holes. A connecting slide rail 52 is provided on the right end of the outer surface of the air collecting pipe 5. The adjusting cap 6 and the air collecting pipe 5 are slidably connected through the connecting slide rail 52. An air outlet is provided on the right end face of the adjusting cap 6. The air outlet and the through hole correspond one-to-one. When air is discharged, the position of the adjusting cap 6 is rotated to change the position of the air outlet, so that the air outlet and the through hole are misaligned, thereby changing the size of the air outlet and realizing the control of the air discharge volume.

[0024] Please refer to Figures 1, 2, and 3. In this embodiment, the diameter of the first vent 7 is smaller than the diameter of the second vent 8, and the first vent 7 and the second vent 8 are evenly spaced. The sealing sleeve 9 is composed of an arc-shaped seat 1 and an arc-shaped seat 2. The surface of the arc-shaped seat 1 is provided with a through groove. The two ends of the arc-shaped seat 1 and the arc-shaped seat 2 are detachably connected by bolts. The length and width of the through groove are adapted to the first vent 7 and the second vent 8. The sealing sleeve 9 is composed of the connection of the arc-shaped seat 1 and the arc-shaped seat 2. During adjustment, the sealing sleeve 9 is loosened, and the position of the through groove is adjusted so that it is adapted to the first vent 7 and the second vent 8, or misaligned with each other, so that the vents are exposed or closed, and air can leak when the airflow passes through, reducing a certain amount of airflow.

[0025] During operation, a high-pressure airflow is delivered by a turbine fan and blown out from the regulating cap 6 after passing through the air collection pipe 5, thus achieving dust removal. The airflow enters the air collection pipe 5 after passing through the adapter 4 and is blown out through the air outlet on the surface of the regulating cap 6, thereby loosening the sealing sleeve 9. The position of the through groove is adjusted so that it matches or is misaligned with the first air leakage hole 7 and the second air leakage hole 8, so that the air leakage holes are exposed or sealed. When the airflow passes through, air can leak, reducing a certain amount of airflow and changing the flow rate of the high-pressure airflow. At the same time, rotating the position of the regulating cap 6 changes the position of the air outlet, causing the air outlet and the through hole to be misaligned, changing the size of the air outlet, thereby controlling the amount of air output and improving practicality.

[0026] Through the above steps, in the dust blowing operation, a high-pressure airflow is delivered by a turbine fan, and after passing through the air collection pipe 5, it is blown out from the adjusting cap 6 to achieve dust blowing. At the same time, the position of the sealing sleeve 9 is adjusted to expose or close the first air leakage hole 7 and the second air leakage hole 8, thereby allowing air leakage during airflow delivery, reducing the overall airflow, achieving flow controllability, and improving practicality. This solves the problem that existing turbine dust blowing guns are limited by structure, cannot control the flow, cannot meet the needs of precision cleaning, and have low practicality.
