Abstract

A dust-free wall scraper is in the shape of a hollow cylinder; the dust-free wall scraper is provided with a handle on the side face and a circular chamfer on the bottom face. Multiple concentric annulus cutters are arranged on the bottom face; the cross section of each cutter is trapezoidal, the outer side is wider and the inner side is narrower. The concentric annulus cutters are connected onto the same plane by four connection spokes; a groove is formed in the outer side close to the upper bottom face; a collection bag sleeves one end close to the upper bottom face and the plastic bag is tied by a rope on the groove. During use, the outer side of the bottom face of the dust-free wall scraper clings to the wall face, the handle is pulled and pushed back and forth, and putty higher than the wall face is scrapped by the cutters, and falls into the collection bag from a gap between the two adjacent concentric rings. As the circular chamfer is arranged on the bottom face of the hollow cylinder of the dust-free wall scraper, the putty higher than the wall face cannot be scrapped by the edge of the bottom. Therefore all the scrapped putty falls into the collection bag. The dust-free wall scraper has the beneficial effects that the structure is compact and simple, the manufacturing cost is low, the pollution to the environment is avoided, and the construction personnel health is guaranteed.

Description

Dustless wall scraping device

Technical field

The present invention relates to a kind of decorating building finishing instrument, relate to specifically one surface of wall is struck off, but the wall scraping device that does not allow powder of lacquer putty for use on disorderly fly, it belongs to decorations construction tool technical field.

Background technology

Puttying is one indispensable operation in house decoration process.After having scraped putty, in order to pursue the smooth and smooth of surface, common way is to wait to parch afterwards with sand paper, to be polished in putty surface.In bruting process, dry and hard putty has become dust again, under the instigating of sand paper, spreads in air as one strand of white cigarette, is shrouding on-the-spot constructor.Particularly, in the bruting process on roof, dust directly drops on constructor's body, contacts with eye, ear, nose, skin, even enters in body, to their healthy great threat that causes.

In the course of the work, dust is easy to be inhaled into tracheae, alveolar to constructor.After dust suction lung, majority is delayed in alveolar.Just can cause pulmonary lesion through a series of stimulation, chemistry and immune effect, comprise that inflammation in respiratory system and pulmonary ventilation function decline.

The approach that dust enters lung is by the upper respiratory tract, comprises nose, pharynx, bronchus, and in this course, part dust can stay in the upper respiratory tract, and mucomembranous epithelial cell is produced to mechanical stimulus and damage.If connect on a small quantity dirt, can automatically discharge by human body physiological function, if but soakage is greater than discharge rate, will produce all pathologies.As on the impact of nose, the longest what see is to bring out rhinitis sicca, be secondly hypertrophic rhinitis, disease is seen mycteroxerosis, nasal obstruction, nasal membrane hyperemia, the thing that point oozes increases; Impact on pharynx is mainly to bring out chronic pharyngitis, and pharyngeal not well, the pharyngalgia pharynx that is dried, coughs up phlegm is itched; Be mainly to bring out chronic bronchitis on bronchial impact, sometimes also can bring out asthma.

Eyes are one of organs accurate, the most easily damaged in human organ.Eye conjunctivitis may cause that the allergy of conjunctiva is relevant with dust with pteryium genesis mechanism, and dust exposure concentration is high, the time long, the incidence of disease is just high.

Dust enters external auditory meatus, is mixed in sebum, can form ceruminal plug, if like this for a long time, can cause the generation of ear's inflammation.

Dust is stained with to hand, flies at airborne granule dust simultaneously, also can fall constructor's hair, on the face with neck on, have spread effect to mucocutaneous, if meet sweat solution hot summer days, produce alkaline matter, just larger to Mucocutaneous stimulation.

For ensureing the healthy of constructor, a kind of invention of dustless Puttying instrument is very necessary.

Summary of the invention

The object of the invention is to design a kind of dustless Puttying instrument, can not cause in use environment pollution, can be to constructor's healthy generation harm yet.

The object of the invention is to be achieved through the following technical solutions:

The profile of dustless wall scraping device is hollow cylindrical, and handle is equipped with in side, and lower bottom part is with circular arc chamfering.On bottom surface, have many donut cutters, the cross section of cutter is trapezoidal, and outside is wider, and inner side is narrower.The annular cutter of concentric circles connects spoke with four and connects at grade.The outside of close upper bottom surface is with fluted, and collecting bag is enclosed within the one end near upper bottom surface, and polybag is tightened with rope at groove.When use, metope is close to in the outside, bottom surface of dustless wall scraping device, drawing handle back and forth, cutter just scrapes off the putty of metope the raised area, and falls in collecting bag from the gap location between two neighboring concentric annulus.Because dustless wall scraping device hollow cylinder lower bottom part is with circular arc chamfering, therefore bottom margin can not scrape off the putty of metope the raised area.Like this, within the putty scraping off from metope all falls into collecting bag.

Beneficial effect of the present invention is: compactness simple for structure, manufacture adult cheap, avoid environment pollution and ensure constructor healthy.

Brief description of the drawings

Fig. 1 is schematic diagram of the present invention.

Label declaration: 1 circular arc chamfering, 2 hollow cylinders, 3 grooves, 4 connect spoke, 5 cutters, 6 handles.

Detailed description of the invention

Dustless wall scraping device, is characterized in that: its profile is a hollow cylinder (2), and handle (6) is equipped with in side, and lower bottom part is with circular arc chamfering (1).On bottom surface, have many donut cutters (5), the cross section of cutter (5) is trapezoidal, and outside is wider, and inner side is narrower.The annular cutter of concentric circles (5) connects spoke (4) with four and connects at grade.Fluted (3) are with in outside near upper bottom surface, and collecting bag is enclosed within the one end near upper bottom surface, and polybag is tightened with rope at groove.When use, metope is close to in the outside, bottom surface of dustless wall scraping device, drawing handle back and forth, cutter (5) just scrapes off the putty of metope the raised area, and falls in collecting bag from the gap location between two neighboring concentric annulus.Because dustless wall scraping device hollow cylinder lower bottom part is with circular arc chamfering, therefore bottom margin can not scrape off the putty of metope the raised area.Like this, within the putty scraping off from metope all falls into collecting bag.

Claims

1. dustless wall scraping device, is characterized in that: its profile is a hollow cylinder (2), and handle (6) is equipped with in side, and lower bottom part is with circular arc chamfering (1); On bottom surface, have many donut cutters (5), the cross section of cutter (5) is trapezoidal, and outside is wider, and inner side is narrower; The annular cutter of concentric circles (5) connects spoke (4) with four and connects at grade; Fluted (3) are with in outside near upper bottom surface, and collecting bag is enclosed within the one end near upper bottom surface, and polybag is tightened with rope at groove; When use, metope is close to in the outside, bottom surface of dustless wall scraping device, drawing handle back and forth, cutter (5) just scrapes off the putty of metope the raised area, and falls in collecting bag from the gap location between two neighboring concentric annulus; Because dustless wall scraping device hollow cylinder lower bottom part is with circular arc chamfering, therefore bottom margin can not scrape off the putty of metope the raised area; Like this, within the putty scraping off from metope all falls into collecting bag.
