BACKGROUND

Technical Field

Exemplary embodiment(s) of the present disclosure relate to vacuum hose attachment and, more particularly, to a specially configured venturi-style vacuum-boosting hose attachment that is connected to a conventional dust collector/cyclone dust collector system having a reduced-diameter intake hose, wherein the venturi-style vacuum-boosting hose attachment increases velocity, air flow, and suction by decreasing the pressure and increasing the velocity via the venturi effect while also increasing air flow and velocity within the attached ducting by means of a secondary inlet.

Prior Art

Dust collectors are high-volume low-vacuum devices that are commonly used in production and home workshops to capture dust and other debris from larger dust producing equipment. They keep shops clean, while also providing clean breathable air. Many different types of dust collectors are available for use. In smaller production and home workshops, 1.5-3 hp single stage dust collectors or 1.5-7 hp two-stage cyclone dust collectors are used to capture dust and provide good filtering with HEPA filters down to 0.3 Micron. Dust collectors provide higher air flow, have large dust containers, and they separate dust efficiently and effectively without clogging.

Shop vacuums work differently and are low volume high-vacuum devices that can be attached directly to smaller tools to take in the dust created while using the tool. But they have issues for example, in the case of wood working machines, dust is created so quickly it clogs the filter causing the shop vacuum to lose suction and become ineffective. Bags are available to provide a first level of separation for the dust and other debris. Shop vacuums produce low air flow and are not suitable for larger dust producing machines limiting their use with in the wood workshop.

Smaller cyclone dust separators can be purchased and fitted to the top of a five-gallon bucket. Cyclone dust separators use the centrifugal forces of rotating air to throw the dust and debris to the outside walls of the separator where gravity then allows the dust and debris to fall into the collection vessel. These smaller cyclones are connected in line with the tool and the shop vacuum for dust separation, but they further reduce the cubic feet/minute (CFM) of the smaller diameter hoses lowering their effectiveness on large dust producing tools.

Wood workers currently need two dust collection devices: a small shop vacuum/extractor for small tools and a large dust collector for large tools for proper dust collection.

While trying to get the benefits of the larger dust collectors and cyclone systems, wood workers try to connect a smaller diameter vacuum hose (e.g., 1.5-inch) to a large dust collection system, and until now it simply did not work. The duct velocity drops to under 1000 feet per/minute (FPM)/100 CFM, with this setup, and at that flowrate the large dust collector and cyclone becomes ineffective and there is no longer dust separation within the cyclone due to the low air flow rate, and there is also no increase in suction. The reduced air flow rate also causes debris and dust to fall out of the air stream and clog the ducting system.

Accordingly, a need remains for venturi-style vacuum-boosting hose attachment in order to overcome at least one of the above-noted shortcomings. The exemplary embodiment(s) satisfy such a need by a specially configured venturi-style vacuum-boosting hose attachment connected to a conventional dust collector/cyclone dust collector system/having a reduced-diameter intake hose, that is convenient and easy to use, non-clogging, lightweight yet durable in design, versatile in its applications, and configured to increase velocity, air flow, and suction by decreasing pressure and increasing velocity via the venturi effect. The present disclosure eliminates the need for the smaller shop vacuum/extractor in a wood shop environment making it easier with only one dust collection device that filters and separates dust effectively and efficiently.

BRIEF SUMMARY OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENT DISCLOSURE

In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide a specially configured venturi-style vacuum-boosting hose attachment that is connected to a conventional dust collector/cyclone dust collector system having a reduced-diameter intake hose, wherein the venturi-style vacuum-boosting hose attachment increases velocity, air flow, and suction by decreasing the pressure and increasing the velocity via the venturi effect while also increasing air flow and velocity within the attached ducting by means of a secondary inlet. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a venturi-style vacuum-boosting hose attachment including a single and unitary body having a centrally registered longitudinal axis. Such a body includes a primary inlet located at a proximal end of the body and having first venturi passageway, a secondary bell-mouth inlet contiguous with the primary centrally disposed inlet and having a second venturi passageway, and a tail cone contiguous with the secondary inlet and having a third passageway terminating at an outlet located at a distal end of the body. Advantageously, the secondary inlet is configured to feed smooth air through the throat to the tail cone with increased velocity and egress via the outlet. Advantageously, the first venturi passageway, the second venturi passageway, and the tail cone are configured to modify a high-volume, low vacuum airflow source into a low-volume, high-vacuum airflow upstream of the primary inlet. Advantageously, the first venturi passageway, the second venturi passageway, and the tail cone are configured to enable the use of smaller hoses and smaller existing dust ported tools on larger existing dust separators and existing cyclone dust collection systems. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the primary inlet has a primary opening centrally circumscribed about the centrally registered longitudinal axis. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the primary opening has an inner diameter converging distally towards the second inlet. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the first venturi passageway begins at the proximal end of the body and terminates at a beginning of the second venturi passageway. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the first venturi passageway and the second venturi passageway are coaxially aligned and contiguously disposed at an end-to-end configuration along the centrally registered longitudinal axis. The throat is downstream of the first venturi passageway and the second venturi passageway. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, an initial diameter of a proximal end of the first venturi passageway is greater than an ending diameter of a distal end of the first venturi passageway. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the secondary inlet has a bell-mouth shape and is located downstream of the primary inlet. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, a diameter of a proximal end of the second venturi passageway is greater than a diameter of a distal end of the second venturi passageway. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, the diameter of the distal end of the second venturi passageway is integral with a proximal end of the tail cone. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, a diameter of the proximal end of the tail cone is less than a diameter of the outlet. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

In a non-limiting exemplary embodiment, an entire longitudinal length of the body spans from the primary inlet to the outlet. Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.

The non-limiting exemplary embodiment(s) is/are referred to generally in FIGS. 1-10 and is/are intended to provide a specially configured venturi-style vacuum-boosting hose attachment 10 connected to a conventional dust collector/cyclone dust collection system 11 having a reduced-diameter intake hose 12, wherein the venturi-style vacuum-boosting hose attachment 10 increases velocity, air flow, and suction by decreasing pressure and increasing velocity via the venturi effect, while also increasing air flow and velocity within the attached ducting by means of a secondary inlet 30. It should be understood that the exemplary embodiment(s) may be retrofitted onto a variety of dust collectors, cyclone dust collector, etc., and should not be limited to any particular variety of dust collectors, etc. described herein. Thus, various embodiments of the present disclosure are compatible with both dust collectors (e.g., for use with larger, stationary machines such as a table saw and a planer, for example) and smaller, portable power tools).

Referring to FIGS. 1-10 in general, in a non-limiting exemplary embodiment(s), the present disclosure relates generally to increasing the effectiveness of dust separation and collection systems 11 while enabling the use of smaller hoses 12 and smaller dust ported tools on larger dust separators and collection systems 11. Specifically, the present disclosure improves the suction, velocity, and airflow of dust separation and collection systems 11 and is suitable for use in many applications.

The venturi-style, vacuum-boosting hose attachment 10 yields the new, useful, and unpredictable result of boosting the vacuum of a gas/liquid source already under vacuum. It is not powered by compressed air or any other power source. Rather, it uses the gas/liquid source under vacuum and the venturi effect to increase the pressure differential which pulls in more gas/liquid at a higher velocity into a primary inlet 20 while also pulling into a secondary inlet 30. Advantageously, the venturi configuration is not standard because it is used in reverse of a normal venturi tube injector or eductor. The present disclosure provides a new venturi structure including a venturi vacuum booster that converts a high-flow, low-vacuum source into a low-flow, high-vacuum source.

There are many uses for this new venturi structure. For example, it can be employed in dust collection systems 11 to boost the velocity, airflow, and suction of smaller vacuum hoses 12 when connected to a dust collection system 11.

In a non-limiting exemplary embodiment, the hose attachment 10 can be retrofitted to various sizes and fit commercial and other home applications and not just for wood working. The throat diameter 18 and length affect both airflow and suction. The tail cone 45 angle also affects maximum vacuum. A smaller throat diameter 18 decreases airflow but increases suction.

In a non-limiting exemplary embodiment, an adjustable primary intake portion (passageway) can move in or out changing the distance of the primary inlet 20 from the throat 18 to enable vacuum adjustment.

In a non-limiting exemplary embodiment, the hose attachment 10 can be used for dust collection, boosting hot tub filtration, pool filtration/skimmer suction booster, vacuum hold down, vacuum lifting devices, aerospace applications, automotive applications, HVAC return systems, vacuum cleaners, aquarium filtration, etc.

In a non-limiting exemplary embodiment, the hose attachment 10 includes a venturi tube 13 having two inlets 20, 30 and one outlet 40. A primary central inlet 20 functions as a first venturi passageway 21 and fits a universal shop vacuum fitting of 2.25 inch. A secondary (intermediate) bell-mouth inlet 30 functions as a second venturi passageway 31 and feeds smooth air through the throat 18 to the tail cone 45 with increased velocity. The outlet 40 is located at a distal end 41 of the body 15 (e.g., long tail cone 45 end). Such an outlet 40 connects directly to a 4-inch dust collection fitting. Such a structural configuration of the body 15 increases suction, velocity, and airflow of the reduced diameter hose 12 attached to the primary central inlet 20 and allows a user to employ smaller dust ported tools on larger dust separation and collection systems 11.

In a non-limiting exemplary embodiment, the venturi-style, vacuum-boosting hose attachment 10 increases the airflow and velocity to the attached dust collector or ducting system 11 by way of the secondary (intermediate) inlet 30, which allows proper airflow to prevent chips and dust from building up in the duct. The secondary (intermediate) inlet 30 also allows in an increased airflow when the primary (initial) inlet 20 is fully blocked off, thereby producing maximum sealed suction. This increased airflow ensures proper operation of cyclone dust separators and dust collection systems 11.

In a non-limiting exemplary embodiment, the primary (initial) inlet 20 tapers inwardly towards a centrally registered longitudinal axis 17 from a standard shop vacuum fitting of 2.25-inch to a smaller diameter (e.g., 1 to 1.25 inches) to increase velocity and allow more airflow into the secondary bell-mouth (intermediate) inlet 30. The bell-mouth intake 30 (secondary inlet) preferably has an inwardly flanged lip (about a 1 to 2 inch radius) converging towards the centrally registered longitudinal axis 17, which allows for smooth and even entry of air at higher velocities into the venturi throat 18 and thereby increases the differential pressure.

In a non-limiting exemplary embodiment, the throat 18 is 1 to 2 inches in diameter and has a length of 0-1 diameter. The tail cone 45 has a shallow angle of about 4-6 degrees diverging away from the centrally registered longitudinal axis 17, and promotes maximum airflow recovery and increase differential pressure. The outlet 40 at the distal end 41 of the tail cone 45, of the 4-inch embodiment, fits a standard 4-inch dust collector fitting. Of course, embodiments of the present disclosure may be retrofitted to connect to a variety of adapters (e.g., Nordfab metal ducting, flange adapters for other popular ducting types, standard size SDR PVC reducers, etc.)

In a non-limiting exemplary embodiment, the venturi-style, vacuum-boosting hose attachment 10 converts the excess airflow of larger dust collector/cyclone separators from a high-volume, low-vacuum airflow to a low-volume, high-vacuum airflow. This allows the employed of smaller dust ported hoses 12 and tools, on the large dust collectors (e.g., router tables, track saws, dust boots 57, pocket hole fixtures, CNC router tables 58, hand sanders 59 etc.).

In a non-limiting exemplary embodiment, larger and smaller models of the venturi-style, vacuum-boosting hose attachment 10 include a 6-inch to 4-inch model that can boost airflow through a smaller 4-inch port and increase suction and velocity

Referring to FIGS. 1-10 in general, the venturi-style vacuum-boosting hose attachment 10 including a single and unitary body 15 having a centrally registered longitudinal axis 17.

Advantageously, the secondary inlet 30 is configured to feed smooth air through the throat 18 to the tail cone 45 with increased velocity and egress via the outlet 40. Advantageously, the first venturi passageway 21, the second venturi passageway 31, and the tail cone 45 are configured to modify a high-volume, low vacuum airflow source into a low-volume, high-vacuum airflow upstream of the primary inlet 20. Advantageously, the first venturi passageway 21, the second venturi passageway 31, and the tail cone 45 are configured to enable the use of smaller hoses 12 and smaller existing dust ported tools on larger existing dust separators and existing cyclone dust collection systems 11.

Such a structural configuration yields the new, useful, and unexpected result of improving air flow and suction while increasing ducting velocity.
