Commercial vacuum hose clearing apparatus

A hose clearing apparatus has a cylindrical body, a fluid coupler on the rear side, and a fluid nozzle on the front side. A method of clearing a hose involves coupling a fluid to the fluid coupler, adjusting the fluid nozzle to achieve the desired spray, powering on the vacuum with the hose coupled thereto, inserting the front of the body and accompanying nozzle into the hose, and allowing the hose to traverse through the hose.

TECHNICAL FIELD

The present disclosure relates to commercial vacuum hoses. More particularly, the present disclosure relates to an apparatus for clearing debris and build-up from the inside of the vacuum hose.

BACKGROUND

Commercial carpet cleaning systems typically rely on hoses of significant length. Over time, sediment can build-up in the hose, and debris can become lodged therein. As a result, the hose not only becomes less efficient, but is significantly heavier. This increases the time and effort it takes a worker to clean carpets. Because of the significant length of the hose, methods of cleaning the inside, such as flushing, are ineffective. Because of this problem, simple devices, such as a rag tied to a rope, have been used to attempt to clear the hose. However, merely pulling a rag through the hose using a rope also fails to dislodge debris or adequately remove build-up. Because an adequate method of clearing the hose is not found in the art, it is common for carpet cleaners to simply discard their hoses and buy new hoses when they become overly clogged. This is expensive and adds unneeded waste to landfills.

Accordingly, there remains a need for a hose clearing device that can adequately clean the full-length of the hose, thereby extending the life of the hose. This allows a worker to clean carpets more efficiently and with less cost. The present invention seeks to solve these and other problems.

SUMMARY OF EXAMPLE EMBODIMENTS

As previously discussed, there is a need for a hose clearing device that can adequately clean the full-length of a commercial vacuum hose, thereby extending the life of the hose. This allows a worker to clean carpets more efficiently and with less cost. The hose clearing apparatus disclosed herein solves these needs and others.

In one embodiment, as shown inFIGS. 1-3, a hose clearing apparatus100comprises a cylindrical body102, a fluid coupler104on the rear side of the body102and a fluid nozzle106on the front side of the body102. The body102may be manufactured from aluminum so as to be lightweight and not susceptible to corrosion. However, other materials may also be used, such as plastics, carbon fibers, metals, or wood. The body102may comprise a rear wall103with cylindrical sidewall105extending therefrom. The sidewall105may have a center bore107, creating a void for receiving the nozzle106. The sidewall105may comprise a front lip109. Front lip109aids in clearing debris as the hose clearing device100traverses through a hose by pushing debris. It will be understood that the nozzle106and fluid coupler104are coupled to the body102by passing through an aperture in the rear wall103(not visible). For example, the nozzle106may be threadably coupled to the fluid coupler104. However, in other embodiments, the hose clearing apparatus100may be of single manufacture or with at least one of the coupler and/or nozzle being an integral part of the body102. The fluid coupler104may be of any standard coupler in the art, including a quick-coupler, threaded coupler, or similar. The fluid coupler104may also be male or female.

In one embodiment, as shown inFIGS. 4-8, a method of clearing a vacuum hose using a vacuum hose clearing apparatus100comprises coupling a fluid hose108to the fluid coupler104. As used herein, the word fluid refers to any fluid, including liquids and gases. In one embodiment, water is the preferred fluid due to its availability and low cost. However, cleaning chemicals or other agents may also be used. Once the fluid hose108is coupled to the fluid coupler104(e.g., standard quick-coupler115), the fluid nozzle106may be adjusted to achieve the desired spray. As shown inFIG. 5, the nozzle106may be of a cone jet sprayer, creating a cone spray111which sufficiently sprays the inner circumference of the vacuum hose110. With the desired spray achieved, the vacuum hose110is coupled to the vacuum and the vacuum is powered on. As shown inFIGS. 5-6, the user then inserts the hose cleaning apparatus100, nozzle106first, into the hose opening112. Preferably, the outer circumference of the sidewall105is just smaller than the inner diameter of the hose110. As a result, the vacuum pressure pulls the hose clearing apparatus100through the vacuum hose110. As the hose clearing apparatus100traverses through the hose110, the spray111dislodges debris and sediment, which then gets sucked by the vacuum through the hose110as well. The debris and sediment are then received into the vacuum's container. In addition, the body102also aids in clearing debris as the body102is sucked through the vacuum hose110. As understood, this method of clearing a vacuum hose is substantially better than the prior art. The combined use of a sprayer (i.e., nozzle106) and body102that can be sucked, using vacuum pressure, through the vacuum hose110while the vacuum simultaneously collects the debris and water, is a significant improvement in the art, leading to a prolonged life for the vacuum hose110, which saves cost for a user while reducing environmental impact (less plastic waste).

In some scenarios, it may be beneficial for a user to maintain control of the speed with which the hose clearing apparatus100traverses through the vacuum hose110. This can be accomplished by the user maintaining a grip on the fluid hose108. This may allow the hose clearing apparatus100to move slower through the hose, clearing more debris. As shown inFIG. 8, once the hose clearing apparatus100reaches the vacuum inlet114, the process is complete. In a preferred embodiment, the sidewall105has an outer circumference that exceeds the inner diameter of the vacuum inlet114, thereby prohibiting the hose clearing apparatus100from entering and damaging the vacuum. With the hose clearing apparatus100now at the vacuum inlet, the hose clearing apparatus100may be disconnected so that the fluid hose108may be easily withdrawn from within the vacuum hose110. These steps may be repeated for any number of hoses and hose lengths, depending upon the length of the fluid hose108and the vacuum suction pressure.

While the nozzle106has been described as cone-shaped and adjustable, such is not required. In other words, the nozzle may have a fixed (non-adjustable) cone spray pattern; in another embodiment, the nozzle may be adjustable to non-cone shaped spray patterns. Further, while water and chemical liquids were described, pressurized air may also be used without departing herefrom.

FIGS. 9-11illustrate a hose clearing apparatus200comprising a cylindrical body202, a fluid coupler204on the rear side of the body202and a fluid nozzle206on the front side of the body202. The body202comprises a rear wall203with cylindrical sidewall205extending therefrom. The sidewall205has a center bore207, creating a void209for receiving the nozzle206. As shown inFIG. 11, the nozzle206may extend longitudinally beyond the front edge210of the sidewall205, which ensures that the fluid exiting therefrom does not contact the sidewall205and instead contacts the inner circumference of the vacuum hose. It will be understood that the nozzle206may be threadably coupled to the fluid coupler204by passing through an aperture in the rear wall203. For example, the nozzle206may comprise a male component that passes through the rear wall203. The fluid coupler204may comprise a female end for coupling to the male end of the nozzle206. This configuration secures and centers the nozzle206within the void209.

While the fluid nozzle206has been illustrated as within a void209created by a bore207, such is not required. In other words, the body need not have a bore and may instead be a puck with the nozzle and fluid coupler extending from each side of the puck, neither of which would be within a void created by sidewalls. Alternately, the fluid coupler may be within a void, rather than the fluid nozzle.

Accordingly, it is clear from the foregoing description that the hose clearing apparatus described herein solves the need for a hose clearing device that can adequately clean the full-length of a hose, extending the life of the hose. This allows a worker to clean carpets more efficiently and with less cost. While vacuum hoses were used as an example herein, it will be appreciated that the hose cleaning apparatus described herein may be used with any type of hose. For example, if used with a non-vacuum hose, the hose clearing apparatus may advance through the hose by a user exerting a force on the attached fluid hose, pushing the hose clearing apparatus and fluid hose through the hose to be cleaned. However, it will be understood that in the preferred embodiment, the outer circumference of the hose clearing device100,200is slightly less than the inner circumference of a vacuum hose so that vacuum pressure pulls the hose clearing device through the vacuum hose, which is an improvement over methods in the art.

Exemplary embodiments are described above. No element, act, or instruction used in this description should be construed as important, necessary, critical, or essential unless explicitly described as such. Although only a few of the exemplary embodiments have been described in detail herein, those skilled in the art will readily appreciate that many modifications are possible in these exemplary embodiments without materially departing from the novel teachings and advantages herein. Accordingly, all such modifications are intended to be included within the scope of this invention.
