Description

Odor air exhaust system {MALODOR AIR EXHAUST SYSTEM}

The present invention relates generally to an air exhaust system and more particularly to an exhaust system for effectively removing odor farts emitted by a person sitting on a seat located in an enclosed area.

Air exhaust systems are generally provided in interior areas, particularly in interior areas where space is limited, such as a room or the interior of a car. Such a system is basically intended to remove odorous air from this area and replace it with fresh air from the outside atmosphere. The system consists largely of an air intake port located on the side wall or ceiling of this area and a duct connected from the intake port to an exhaust port in communication with the outside atmosphere. A blowing fan is located in this duct to draw in odorous air from the interior area and discharge it out through the exhaust port. Such a system is not practical to eliminate unpleasant odor farts emitted by a person sitting on a seat located in an enclosed area, because the unpleasant odor of the fart is completely drawn into the interior area before being slowly escaped by the exhaust system. Because it will spread. Thus, the unpleasant odor of the fart will seep through and inhale to others located in the same area before it is subsequently slowly replaced with fresh air outside.

Most people produce farts of about 1 to 3 pints a day and emit about 14 malodorous gases. Farts themselves are not life threatening, but they can certainly cause social embarrassment. People who fart openly are usually ridiculed and even evaded by social groups. This distress is often the reason for finding solutions to open air farts.

The exhaust system is pending in the U.S. Pat. Patent Application No. 11 / 903,699. However, this system is difficult to install in a car or room because extensive changes must be made to the car or building building. The present invention provides a system that more efficiently improves the elimination of odor farts as well as filtering the internal air in warm-up mode in an enclosed area.

It is a primary object of the present invention to provide an exhaust system that efficiently removes farts emitted by a person sitting on a seat located in an enclosed compartment or room.

Referring to the drawings, FIG. 1 shows an air intake opening 10 formed in the upper portion 11 of the seat 12. The suction opening 10 is preferably an elliptical shape having a large diameter of at least 10 cm and the suction opening 10 is located at the center of the seat at the position where the person sits on the seat so that the fart discharged from the person is the suction opening. Allow for immediate discharge to (10). For sheets with a rigid upper portion, the suction opening 10 can be covered with a screen or grate having a plurality of openings, and for a soft upper portion provided with a covering sheet material, the same A plurality of vent holes may be formed in the sheet material for the purpose. The inlet vent connection 13 is mounted below the suction opening 10 of the seat. The inlet vent connection 13 is folded in an inverted truncated cone shape with a larger upper end 14 having the same shape and size as the intake opening 10 and a circular lower end 15 having a diameter smaller than this upper end. It is a tube form that can. The upper end of the inlet vent connection 13 is mounted to the suction opening 10 of the seat 12. The inverted truncated cone shape of the inlet vent connection 13 enhances the flow of air from the intake opening 10 to the connection.

The lower end 15 of the inlet vent connection 13 is connected to the upper end 16 of the L-shaped manifold 17. The sensor fan 18 is selectively mounted transversely to the mounting portion between the inlet vent connection 13 and the upper end 16 of the manifold 17. The sensor fan 18 operates to suck air and farts from the suction opening 10 into the L-shaped manifold 17.

The gas sensor 19 is mounted on the side wall of the L-shaped manifold 17 and positioned adjacent to the inlet opening 10 as shown in FIG. 2 to fart into the inlet vent connection 13 by the sensor fan 18. As soon as it is discharged it can be detected and inhaled. The gas sensor 19 can detect odor gas concentrations between 1 and 100 ppm and the sensitivity of the system trigger point is adjustable. It has little hysteresis and low power consumption. The gas sensor 19 is inserted through the sidewall of the manifold 17 via a heat shield for the sensor and a Teflon® sleeve that serves as a pressure seal for maintaining air flow within the vent system. The gas sensor 19 is connected to an electrical control module 20 for the system of the present invention. The gas sensor and control module may be made of an integral assembly that may be easily, easily and removably installed in a compartment formed in the seat or simply located under the seat. When simply positioned under the seat, the gas sensor 19 can be inserted through the lower sidewall of the manifold 17 as shown in FIG. 3.

A damper 21 is provided in the manifold 17, which is located adjacent to the lower outlet end of the manifold 17. The damper 21 has the same size as the internal size of the manifold 17 and the damper 21 is in a first position X parallel to the axis of the lower part of the manifold to allow air to flow to the outlet end of the manifold. Operatively controlled by the control module 20 to be at a second position Y transverse to the axis of the manifold so as to be at or at the outlet end. The second clean air outlet 22 is an enclosed area in which air flows out of the manifold through the second clean air outlet 22 when the manifold is blocked by a damper 21 located in the Y position. It is located on the side wall of the front manifold 17 of the damper 21 to reenter it in. This allows odorless clean air to be circulated to the enclosed area in the idle mode of the system.

As shown in FIG. 2, an extension duct 23 is provided to connect the outlet end of the manifold 17 to the outlet duct 24 to allow discharge of unwanted air to the outside atmosphere. The air filter 25 may be selectively mounted between the extension duct 23 and the outlet duct 24 to purify the odor air before discharging the odor air to the outside atmosphere. Alternatively, this air can return to the enclosed area after the malodor is filtered out. One blowing fan 26 with high power may also be provided to the air filter 25 or a plurality of fans may be included adjacent the end of the exhaust vent to improve the intake of exhaust air into the outside atmosphere without filtering. have.

A second seat 12A having a similar assembly and a separate manifold 17A can be included in the system by connecting the manifold 17A to the main extension duct 23. In addition, a plurality of sheets 12A, 12B, 12C may also be included in the system by connecting the manifolds 17A, 17B, 17C to the main extension duct 23 as shown in FIG.

The configuration of the control module 20 and the overall electrical operation system of the system of the present invention for use in an automobile as an exemplary embodiment is shown optimally in FIG. 4. The system of the present invention is activated when a person sits on the seat 12 to turn on the vehicle ignition to the accessory power or to start the vehicle. The weight of the person actuates an occupant sensor switch 27, such as a power interlock micro-switch mounted below the top of the seat, allowing the system to be operated by the electrical power of the vehicle. The sensor fan 18 operates as soon as power is turned on and the system is operated after a short initial warm-up period to allow air in the enclosed area to circulate through the enclosed area in standby mode when the damper 21 is in the enclosed position. Clean air is returned to the enclosed area through the second clean air outlet 22. The standby mode in which the sensor fan 18 operates continuously also improves the efficiency of the system of sucking the fart into the manifold 17 as soon as the fart is discharged by the person sitting on the seat. A manually operated first override switch 28 is provided for turning off the sensor fan 18 and the system if the operator of the vehicle is not desired.

As shown in FIGS. 4 and 5, the control module 20 is also powered by a power supply through the system fuse 29 of the vehicle to operate the gas sensor 19 shown as an integral unit with the control module 20. Is turned on. The gas sensor 19 is set to 7Vdc for the heater power and is powered by a fixed adjustable DC power supply and is excited with a fixed 5Vdc power supply. With these two sensor supply voltages, the sensor output range is from 1 Vdc to 4 Vdc corresponding to about 1 ppm to 100 ppm of the malodorous air concentration, respectively. The sensor output is calibrated to drive an array of Darlington transistors that drive the control relay. This calibration is accomplished with the use of one operational amplifier that is referenced to a negative input by a voltage divider and compares it to the sensor output provided as a positive input. The output of this op amp calibration circuit drives the Darlington transistor relay driver.

The gas detection sensitivity of the system can be adjusted with the calibration amplifier 31. The gas sensor 19 may turn on the exhaust fan 26 through the exhaust fan relay 32 and the relay driver 33. On the other hand, the damper 21 is also operated by the relay driver 33 to be located in the open position X when the exhaust blower fan 26 is operated so that the odorous air is discharged or filtered from the vehicle to the outside atmosphere and then in the cabin. Let's go back to The system can operate in the malodorous air exhaust mode while the gas sensor 19 still detects the presence of malodorous air. The exhaust fan 26 can also be operated continuously for a period of time selected by the operator by turning on the second override switch 34. A mode indicator 35 may be provided to display whether the system is operating in automatic mode or whether the system is operating in one of the ON or OFF override modes, and if present, whether the filter requires replacement. This mode indicator 35 may be mounted in a visible position, such as a dash or seat arm rest of an automobile. The power supply to the control module can also be turned on when the vehicle's ignition switch is switched to the accessory or start position.

In addition, a voice / noise generator 41 may be further provided, and the voice / noise generator 41 may be provided with a specific voice to prevent a person from easily noticing a fart sound that may occur when the user discharges the fart. sound or unspecific noise, and when the user releases the fart, when the voice / noise generator 41 is turned on, a voice or noise that is not easily noticed by the fart sound is generated. You can make the farting person feel less embarrassed or embarrassed. Alternatively, the voice may be popular music or sound music. The voice / noise generator 41 can be activated when the user turns on the user on switch 34 (FIG. 4) or when the user presses a separate on switch.

When the exhaust system of the present invention is used in a seat having a soft or elastic seat top portion with the gas sensor mounted vertically at the bottom of the manifold, due to variations in seat thickness, rigidity and occupant weight, adjustable mounting A tube may be provided to position the gas sensor in the seat. As shown in the exemplary embodiment best shown in FIG. 6, the adjustable mounting tube may be in the form of a tapered tube 36 having a threaded lower end portion 37. The extension tube 36 is a threaded upper part 38 of the threaded base of the base 39 provided in the control module. The gas sensor is then mounted on top of the extension tube 36. The height of the gas sensor extending upward in the seat can thus be adjusted by rotating the extension tube relative to the base 39. The lead wire 40 of the gas sensor extends through the mounting base 39 to connect to the control module.

As shown in the above-described embodiment, the gas sensor 19 and the control module 23 are formed as an integrated assembly. It will also be appreciated that this gas sensor may be provided separately from the lead wires connected to the control module.

While the invention has been shown and described in terms of the preferred embodiments, it will be apparent that various modifications may be made without departing from the spirit and essential features of the invention, and therefore, the invention is to be limited only by the appended claims.
