TECHNICAL FIELD
The present disclosure relates to clearing liquids from hoses and pipes. More particularly, the present disclosure relates to an apparatus for clearing the liquid from the hose or pipe to prevent freezing.
BACKGROUND
Many areas in the world have temperatures that fall to below freezing (32 degrees Fahrenheit). In these areas, it may be difficult to keep conduits, such as hoses and pipes, from freezing due to liquids that remain in the conduit (also referred to herein as the “residue”). For example, a rancher may use a hose to supply his livestock with drinking water. Once the reservoir is full and the rancher turns off the spigot (also referred to as a “faucet”), the hose will likely still have water (residue) inside. This may be due to inclines over which the hose passes, surface tension between the water and the hose, or any number of other factors. If the temperature is either currently freezing or will drop to freezing overnight, the hose may become solidified. When this occurs, the rancher will not be able to supply water to the livestock. Further, in some cases, the expansion of the ice may compromise the hose and/or the spigot. This is an important issue, especially if the spigot is attached to a house/trailer. For example, a garden hose left connected to a home can freeze and create liabilities to the home. Other areas include the use of RVs or other vehicles that may have a water supply that uses a conduit. Further, as mentioned above, hoses alone aren't susceptible to freezing, but pipes and other conduits (e.g., sprinkler systems) may also be subjected to freezing temperatures. In such a scenario, it is important to remove the residue from the conduit before freezing.
One method for ensuring a hose is empty is to disconnect and wind the hose. However, this takes additional time, is cumbersome, and the user must outstretch the hose with each use. Further, if using a pipe or other rigid or semi-rigid conduit, winding is not possible. As such, there is a need to extract liquid from the conduit when not in use that does not require disassembly or winding of the conduit. The present disclosure seeks to solve these and other problems.
SUMMARY OF EXAMPLE EMBODIMENTS
In one embodiment, a conduit clearing apparatus comprises an electric blower, a check valve, and a faucet coupler; the faucet coupler having a first end for threading to a faucet, a second end for threading to a conduit, and a blower connecting port wherein the blower is coupled to the blower connecting port via the check valve. The electric blower is preferably powered by one or more batteries and is activated by a user toggling a switch.
In one embodiment, the conduit clearing apparatus comprises a timer that correlates to the length of conduit being cleared, the timer functioning as the blower power switch.
In one embodiment, the conduit clearing apparatus comprises a thermal control circuit. The thermal control circuit may comprise a temperature sensor chip (e.g., LM35) and a relay. When the temperature falls below a predetermined level (e.g., 34 degrees Fahrenheit), the temperature sensor chip actuates the relay, the relay activating the blower for a predetermined time. The circuit may comprise components known in the art, such as Zener diodes, resistors, and the like to achieve optimal functionality.

As previously discussed, there is a need for an apparatus that can clear a conduit when not in use so as to avoid freezing within the conduit. The hose clearing apparatus described herein solves these needs and others. While the examples herein often refer to a hose, it will be appreciated that any conduit, such as a pipe, is also contemplated herein.
In one embodiment, as shown in FIG. 1, a hose clearing apparatus 100 comprises an electric blower 102, a check valve 104, and a faucet coupler 106. The faucet coupler 106 has a first end 108 for threading to a faucet, a second end 110 for threading to a conduit (e.g., hose, pipe, or equivalent), and a blower connecting port 112 wherein the blower 102 is coupled to the blower connecting port 112 via the check valve 104. The electric blower 102 is preferably powered by one or more batteries and is activated by a user toggling a switch 114. For example, a user would open the faucet valve, wherein water would then pass through the faucet coupler 106 and through the conduit. When the desired water is achieved, the user would then close the faucet valve. A user could then toggle the switch 114, activating the blower 102, wherein the air would pass through the check valve 104 and be forced into the faucet coupler 106 and conduit, thereby clearing the residue within the conduit. The user would then toggle the switch 114 to deactivate the blower 102. With the blower 102 off, the check valve 104 will once again close, prohibiting water from entering the blower 102. The blower 102 may be battery powered, with the batteries being stored in a housing 116 or separate therefrom (e.g., in a housing that is connectable to the blower 102 via a cable, which allows for easy transportation for charging). The batteries may be of any variety (standard C or D batteries, Lithium Ion, etc.), including rechargeable.
In one embodiment, as shown in FIG. 2, the conduit clearing apparatus 200 comprises a timer switch 218 that correlates to the length of conduit being cleared, the timer switch 218 functioning as the blower 202 power switch. For example, if the timer switch 218 is set to 50 feet, the blower may be activated for one minute. A 100-foot hose may require two minutes of blower time, etc. This time may be set by the manufacturer, or may be adjusted by a user during a setup configuration. A control switch 214 determines whether the timer switch 218 is activated. In other words, if the control switch 214 is Off, the blower 202 cannot be activated. If the control switch 214 is toggled to a first position 214A (the “Manual” position), the blower 202 is activated and will remain activated until the control switch 214 is toggled again by a user. In an alternate embodiment, the Manual position 214A is spring-activated. In other words, a user depresses the control switch 214 to the Manual position 214A to activate the blower 202. However, once a user releases the control switch 214, the control switch returns to the Off position. This keeps the keeps the batteries from draining unintentionally. If the control switch 214 is toggled to a second position 214B (the “Auto” position), the blower 202 is only activated when the timer switch 218 is actuated. Once the timer ends, the circuit opens and the blower 202 is deactivated. The timer switch 218 preferably correlates to the length of the conduit. For example, a user would toggle the control switch 214 to the Auto position 214B, and then would actuate the timer switch 218 to the appropriate conduit length (e.g., 100 ft.). The blower 202 would then blow for a predetermined time, calculated to clear a conduit of that length, ensuring the conduit is clear before ceasing. An example wiring diagram is shown in FIG. 3. It will be appreciated that while a control switch 214 is used in this example, the control switch 214 is not required. In other words, the timer switch 218 could be the sole switch for activating the blower 202 without need for the manual override that the control switch 214 provides. In other words, a user could manually operate the blower 202 by merely turning the timer switch 218 to the appropriate length, wherein the blower 202 is activated. As the timer switch 218 counts down, it automatically turns off the blower 202 when reaching zero. It will further be appreciated that the batteries that power the conduit clearing apparatus 200 may be removable or non-removable. In either scenario, a charging port 220 may be used so that a user may charge the one or more batteries contained in housing 216.
Referring to the wiring diagram in FIG. 3, the blower 202 is electrically coupled to the timer switch 218, the control switch 214, and a battery connector 222. As understood, if the control switch 214 is toggled to the Manual position 214A, the circuit between the battery connector 222 and the blower 202 is closed, activating the blower 202. In the Off position, the circuit is open. In the Auto position 214B, the circuit between the battery connector 222 and the blower 202 is dependent upon the state of the timer switch 218.
In one embodiment, as shown in FIG. 4, a hose clearing apparatus 300 comprises a blower 302, a check valve 304, a faucet coupler 306 with a first end 308 for coupling to a faucet 310. The check valve 304 controlling the flow of air from the blower 302 through a port 312 to the faucet coupler 306. The blower 302 may be controlled via a variety of means, such as a control switch 314, a timer switch 318, a flow switch 324, or a thermal switch 326. For example, the blower 302 may be manually activated by a user via control switch 314 (e.g., switching it to “Manual”). The user may also place the control switch 314 on “Manual-Timer” which allows the user to rotate the timer switch 318 to the appropriate time via hose length (or other determination), which shuts off the blower 202 when the timer switch 318 concludes. The control switch 314 may be further toggled to “Automatic-Flow” which controls the blower 202 using both the flow switch 324 and the timer switch 318. For example, the flow switch 324 may comprise a water sensor for determining when water has passed through the faucet coupler 306. The switch is activated when water is detected, with the blower 302 activating upon termination of the water passing through the faucet conduit 306, as measured by the water sensor of flow switch 324. As appreciated from the Fig. water enters from the first end 308, passes by and activates flow switch 324, closes the check valve 304 with downward pressure, and exits into the conduit (e.g., hose or pipe) at the second end 310. Once the water ceases, as sensed by the flow switch 324, the blower 302 is activated for a predetermined time, as set by a user using the timer switch 318. As air enters air intake 303, it passes through the port 312 and forces the check valve 304 open so that air can be forced through the second end 310 and out through the conduit, removing any residue in the conduit. It will be appreciated that a microcontroller or similar device may be used to receive signals from the one or more switches and to control the blower 302.
Continuing with FIG. 4, in a further embodiment, a temperature sensor may also be utilized. For example, thermal switch 326 may comprise a temperature sensor and an indicator light (e.g., LED). The thermal switch 326 may be used in connection with the flow switch 324 to ensure that the blower 302 is only activated when temperatures are approaching freezing. For example, the blower 302 is only activated when several conditions are met: 1) the control switch is set to “Automatic-Temp.”; 2) water is detected via the flow switch 324; and 3) the temperature is at, or below, a predetermined threshold (e.g., 34 degrees Fahrenheit). As appreciated, a microcontroller may receive signals from the one or more switches, process the signals, and activate the blower 302 accordingly. Additional indicators may also be present, such as a battery indicator 328.
While a microcontroller may be used, simple switching mechanisms may also be utilized. Example wiring diagrams are shown in FIGS. 5 and 6. As shown in FIG. 5, the thermal control circuit of the thermal switch 326 may comprise a temperature sensor chip (e.g., LM35) and a relay. When the temperature falls below a predetermined threshold (e.g., 34 degrees Fahrenheit), the sensor chip actuates the relay, the relay activating the blower 302 for a predetermined time according to the timer switch 318. In a simple example, the user would toggle the control switch 314 to Auto and would set the timer switch 318 to the corresponding length of hose. The thermal control circuit as part of thermal switch 326 would be located between the control switch 314 and the timer switch 318. If the temperature falls below the predetermined threshold, the circuit closes, which activates the pre-set timer switch 318. Once the timer switch 318 completes, the circuit is opened and the blower 302 deactivates. In one example, the timer switch 318 must again be reset the following day by the user after using the hose in order for the blower 302 to be temperature activated again. However, in another example, the timer switch 318 remains at the predetermined time for repeated use. The thermal circuit may comprise components known in the art, such as Zener diodes, resistors, and the like to achieve optimal functionality. As shown in FIG. 6, a flow switch 324 may be incorporated into the wiring diagram. Accordingly, once the switch is closed (e.g., water pressure upon resistors, etc.), the circuit closes. If the timer switch 318 and thermal switch 326 are likewise closed, the blower 302 is activated. It will be appreciated that the timer switch 318 may be placed either before or after the temperature sensor, as shown in FIGS. 5 and 6.
As used throughout this disclosure, the term blower refers to any air-generating device that is, preferably, electrically powered. The blower may be of a variety of types, including motor-driven rotary fans, squirrel cage fans, impellers, etc.
In one embodiment, as described earlier, the conduit clearing apparatus comprises a temperature sensor and a microcontroller, wherein the microcontroller is preprogrammed with logic to activate the blower for the user specified time (correlated to hose length or other factors) upon reaching a predetermined temperature (e.g., 34 degrees Fahrenheit). For example, a user may simply toggle the control switch to Auto. Using a temperature sensor and preprogrammed logic, the microcontroller can activate the blower for a specified time. The time may either be input by a user by using an interface and user input buttons, or may simply be configured by the manufacturer for specific lengths (e.g., 100 feet). Additional logic or sensors may also be used to prevent the microcontroller from reactivating the blower after the conduit has already been cleared and the conduit has not been subsequently reused. For example, the check valve may have a spring that prohibits it from fully closing without outside pressure. The check valve could have a contact that closes a circuit when fully closed (i.e., when the faucet is opened and water pushes the check valve closed, the contacts would close the circuit, resetting the microcontroller). In another example, a water detector may be used (which are well known in the art) to reset the microcontroller. Having a microcontroller-controlled conduit clearing device would fully-automate the hose clearing process, with the only remaining step for the user being to ensure the batteries are charged. While a timer system may be used for the length of time a blower is activated, another embodiment uses a pressure sensor. For example, when the blower is activated, a back-pressure is created when the air reaches the water. A level of back pressure continues to exist until the conduit is empty and the air may freely flow therefrom. Therefore, in one embodiment, the blower is controlled using, in combination with other sensors described herein (e.g., temperature), a pressure sensor to determine when the conduit is empty.
In one embodiment, as shown in FIG. 7, a hose clearing apparatus 400 may further comprise a removable battery housing 430. This allows a user to easily remove the battery housing 430 and accompanying batteries for either replacement or recharge. In one example, a user may remove the battery housing 430 and place on a charger, and may insert a second battery housing 430 into the receptacle 432 of the hose clearing apparatus 400 for use. It will be appreciated that electrical contacts 434 on the battery housing 430 make contact with electrical contacts 436 in the receptacle 432. In another embodiment, other means for charging the batteries may be used, such as a solar panel coupled, and configured, to charge the batteries. In such a manner, the batteries need not be removed and/or replaced as frequently.
It will be appreciated that the hose clearing devices described above may be manufactured from integral parts (i.e., the faucet coupler and blower are permanently connected as one unit), or be separate individual components, as shown in FIGS. 8 and 9. In one embodiment, as shown in FIG. 8, a faucet coupler 506 comprises a first end 508 for coupling to a faucet, a second end 510 for coupling to a conduit, and a port 512 for coupling to a blowing device (FIG. 9). The port 512 preferably comprises a means for unidirectional flow (e.g., check valve). For example, a port door 504 functions as a check valve, preventing water from entering the port 512. The port door 504 may be hinged and may or may not be spring-loaded. FIG. 9 illustrates a blowing device 502 (e.g., leaf blower or other air-producing device) for use with a faucet conduit 506. A coupler 503 may couple the blower 502 to the faucet coupler 506. It will be appreciated that any number of couplers 503 may be used, each being configured for a specific type, make, or model of blowing device 502. This allows a user to use a variety of components, some of which they may already own (e.g., leaf blower) for the purpose of clearing residue from a hose. The coupler 503 may be coupled directly to the faucet coupler 506, or may use an intermediary coupler 505. Intermediate coupler 505 is useful when space is limited near the faucet and faucet coupler 506.
It is appreciated from the foregoing that the hose clearing apparatus effectively clears liquid from a conduit to prevent freezing. Further, as outlined in one or more embodiments, the use of temperature sensors allows the conduit clearing apparatus to function based upon temperature, providing peace of mind to a user and overcoming problems in the prior 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.
