- the waste is pumped into the waste receptacle 148 through the passageway 146 which is located inside the waste receptacle 148. Once the waste has been vacuumed into the device, the device is turned off.
- the intake is then returned to the self-cleaning compartment 75 by depressing the pedal of the self-cleaning compa ⁇ ment 75 where it is washed and sanitized employing an automatic process.
- the power is turned off and the removable Uner 143 is disconnected and disposed.
- the hose 40 is then rolled into place at the top of die device or, alternatively, stored within the device,
- Figures 3 and 4 show a more compact embodiment suitable for a handheld embodiment of the present invention.
- Figure 4 shows a more compact embodiment suitable for a handheld embodiment of the present invention.
- a cross sectional view of the back ⁇ f the device also showing various components can be seen m Figure i 1 ,
- the vacuum pump 155 is used to provide suction to suck, various types of solid, uid or mixed solid and liquid matter into the intake system 20 and deposit the matter * o the waste or liner storage and disposal system 140 for disposal.
- the hose 40 is removed ( Figure 6) and then the intake head 27 is moved as shown in Figure 7.
- the intake head 27 is placed in the vicinity of the matter hich the operator wishes to vacuum up, such as pet Utter.
- the vacuum pump 155 sucks ⁇ e matter into the intake head 27 and through the hose 40 for deposit into the removable ner 143.
- the intake head 27 is placed in the self- .'leaning compartment 75 as shown in Figure 10.
- the intake head 27 ncludes a lid 28 as shown in Figure S far reception into the self-cleaning compartment 75 rod for covering the self-cleaning compartment 75.
- the lid 28 is then inserted into a slot 77 defined by the self-cleaning compartment 75 as shown in Figure 10.
- the pump 214 automatically draws fluid fiom the fluid reservoir 212 and dispenses fluid through the spray hose 220 into the self-cleaning compartment 75 for cleaning and sanitizing the intake head 27.
- the hose 40 is shut off.
- the pump 214 and the spray hose 220 are shut off and the vacuum pump 155 then sucks in any waste or liner cleaned off the intake head 27 together with the cleaning fluid, and deposits the waste or litter and fluid into the removable liner of the collection system 143 for disposal.
- This self-cleaning system ensures that we entire intake system 20 is cleaned and sanitized.
- the waste may be hard, dry or froze .
- an operator may use a detachable intake head 27 having rotating blades (not shown) as shown in Figures 14 and 15, Typically these blades (not shown) are located outside a protective cover or grill 30 of the intake head 27 (see Figures 13 and 16) such that the incoming waste is already cut into manageable pieces before being sucked into the intake system 20, Power for the blades (not shown)may be provided from the device's main power supply 400 and controlled through a control panel 26 located on the intake 25.
- the intake head 27 may be lined with noise reduction material (not shown) such as soft thick rubber for reducing the noise during processing of the waste.
- the intake head 27 may include wheels 31 as shown in Figure 12 to conveniently allow forward and backward movement of the intake head 27 during operation. These wheels 31 may be connected to each other by a connecting rod (not shown) and the rod (not shown) may include blades (not shown) in a fan formation. The blades (not shown) allow free rotating movement of the connecting rod for ensuring that the wheels 31 are turned when the intake head 27 is inserted inside the self-cleaning compartment 75 for cleaning. More particularly, spray from a spray jet in the self-cleaning compartment 75 bits the blades (not shown) on the fan thereby rotating the rod (not shown) which in turn rotates the wheels 31 for thorough cleaning.
- the inside of the walls of the hose 40 and the intake head 27 include a spray nozzle 45 as shown in Figure 20 (which also fotms part of the fluid supply system 200 described below).
- the spray nozzle 45 allows the walls of the hose 40 to be washed and lubricated during operation thereby making it easier for the vacuum pump 155 to suck up the litter by clearing the hose 40 for incoming material.
- the spray hose 220 may be activated from the control panel 26, but should only be activated when the vacuum pump 155 is in use.
- the intake head 27 may be protected by a cover grill 30 t ⁇ prevent larger waste material from being sucked into the intake system 20- Further, the grill 30 may be flipped opened or closed by the operator as shown in Figure 17, either by manually opening the grill 30 or through the use of a control handle located on the intake. This is useful in the event that larger material is stuck to the grill 30 owing to the suction power of the intake/vacuum pump 55.
- the grill 30 includes a lock or hook 30a to keep the grill 30 closed.
- a thin rod 30b as shown in Figure 21 connects the lock or hook 30a of the grill to the control panel 26.
- the thin rod 30b can then unlock or push open the grill 30 for pusing any larger material 30 that is too large to pass through the grill 30 off.
- the grill 30 returns to a closed position through the use of a return spring 30c which pushes the thin rod 30b upward to its normal position.
- the inside of the intake head 27 includes a flap 30 which acts as a check valve to allow waste to flow unidirectional ⁇ y toward the waste receptacle 148.
- a second flap (not shown), attached to the opposite wall of the first flap 30, acts as a redundancy system for the first flap 30 and further ensures the unidirectional flow of the waste, which incidentally also segregates the mer po ⁇ ion of the system from the out position, to provide a secondary system to isolate ⁇ e vacuumed waste from the outside environment.
- the flap 30 also prevents waste from failing out of the hose 40 before the hose 40 . placed in the self-cleaning compa ⁇ ment 75.
- the vacuum pump 155 is switched on he flap 30 is opened by the suction power of the vacuum pump 155 to allow incoming naterial to be sucked into the hose 40.
- the flap 30, where attached, defines an opening to ensure that during the cleaning process the fluid by through both sides of the flap 30 thereby cleaning the flap 30.
- the general operation of the intake system 20 is as follows:
- the main power button 405 is turned on thereby providing power to the system.

Accordingly, as the motor driving gear turns the gear of the screw cap 152 to tnnect the screw cap 152 with the passageway 146, the motor driving gear also turns the lounted Uft gear in the same direction thereby raising the carrier hanger 158 and the ⁇ spending hanger up in a coordinated way.
- the electric motor urns the motor gear in the direction opposite as when the screw cap 152 is being jonnected to the passageway 146.
- the motor gear turning in the opposite direction causes ⁇ he screw cap 52 to disconnect from the passageway 146 and, simultaneously causes the mounted hft gear to turn in the opposing direction thereby lowing the carrier banger 158, thereby lowering the suspendmg hanger to coordinate with the unscrewing of the screw cap 152,
- the cooperating relationship between the gears can be seen in Figures 27, 38 and 39.
- workshop improvements which could coordinate or perform theses same tasks (such as by more motors, fewer gears, and some sensors and control logic onboard the system) which would be obvious to one designing similar automated connecting systems.
- the litter storage and disposal system 140 may include a pullout hanger as shown in Figures 28 and 36 for pulling the removable liner 143 away from the screw cap 152.
- the pullout hanger also includes a gear which is driven by the motor gear.
- the carrier hanger 158 still suspends the screw cap 152 hanger.
- the motor gear continues to turn.
- a push rod attached to the pullout hanger engages the pullout hanger thereby causing the pullout hanger to travel in the same direction as the pullout hanger gear-
- the pullout hanger pivots between the space between the suspending hanger and the top walls of the carrier drawer 156.
- the suspendmg hanger continues to he upheld by the spout of the removable liner 143 which is, at this point, still installed in the screw cap 152 and is already tied up.
- the pullout hanger continues to move forcing the attached seal of the removable Uner 143 spout to pull out of the screw cap 152.
- the electric motor is timed to ensure that the pullout hanger does not continue to pivot further than necessary.
- the removable Uner 143 is still • pended or hanging inside the screw cap 152 by the hanger which is fitted into the ting space of the seal of the screw cap 152. Accordingly, the removable liner 143 is not moved from the screw cap 152 until the drawer 156 is pulled out which pulls the pullout inger away from the device.
- the pullout hanger then hooks or puUs the removable Uner 13 spout away from the screw cap 152 after the screw cap 152 has been disconnected and fter the removable liner 143 spout is sealed or tied up.
- a spring attached to the pullout hanger as shown in Figure 36 biases the pullout anger to its original position once the removable liner 143 drops into the drawer 156 of tie waste receptacle 14S awaiting disposal-
- the spout of the removable liner 143 that is disconnected or pulled out from the screw cap 152 now falls inside the carrier drawer 156 where it is ready for disposal.
- the removable liner is already tied up and fully disconnected from the screw cap 152 assembly equipment, ready for the operator to carry the carrier drawer 156 with the removable liner 143 away for disposal of the removable Imer 143.
- the drawer 156 depresses a switch inside the waste receptacle 148 which starts or turns on the electric motor (two-way) to connect the independent screw cap 152 and the removable Imer 143 with the passageway 146.
- the carrier hanger 158 slides underneath the suspending hanger such that when the drawer 156 electric motor starts turning, the mounted lift rises to carry the suspending hanger up while connecting the screw cap 152 with the passageway 146.
- the electric motor wiU turn the pullout hanger gear upward but does not perform any function when the screw cap 152 is being connected.
- the removable liner 143 may be comprised of durable, puncture-resistant and waterproof or otherwise impermeable material to prevent breakage and leakage as the removable liner 143 is filled up.
- the removable liner 143 may also be comprised of a biodegradable material if the device is used for pet litter to reduce the environmental impact of that use of the device. If the removable liner 143 is biodegradable then it may be composed of a material such that the removable liner 143 degrades or decays from the outside - in. Still further, the removable liner 143 may be comprised of medical-grade waste disposal material to provide maximum protection against removable Uner breakage or puncture where the waste being handled is a biobazard or includes sharps.
- the removable liner 143 may also be opaque such that an operator does not see the contents of the removable Imer 143 upon disposal.
- the removable Imer 143 may include a square (or other "grippable" and symmetrical shape) holder 162 which is hinged m middle of the opening of the removable Uner 143 as shown in Figures 37 and 40, A square holder 162 may fold into an arrow shape ( Figure 41) for insertion into the screw cap 152 during installation.

- the screw cap 152 tightens, the shaped wrench- like gripping and turning slot 77 flattens thereby holding the folded holder 162 in its flattened state.
- the holder 162 may be any shape that fits into the shaped slot 77 of the screw cap 152 provided that when fitted into the shaped slot 77, the holder will turn when the screw cap 152 turns for sealing the removable Uner 143.
- the holder 162 and the screw cap 152 form a watertight or functional seal once the holder is flattened within the screw cap 152 and secured.
- the removable liner 143 is sealed, closed or tied up during the disconnection of the screw cap 152 from the passageway 146. More specifically, when disconnecting the screw cap 152 from the passageway 146, the motor gear turns the screw cap 152.
- the screw cap 152 having ⁇ holder sealed within the shaped slot 77, begins to turn the holder and the removable liner 143.
- the weight of the waste within the removable Uner or shape of the liner 143 prevents it from turning or continuing to turn with the holder and, accordingly, the spout continues to turn but the removable liner 143 does not.
- the walls of the spout of the removable liner 143 are lined with flexible wire which holds its shape when bent or deformed. When the spout is twisted but the removable liner 143 remains stationary, the wire biases the spout in a closed or sealed position. As a result, the removable liner 143 is sealed sufficient for disposal.
- the suspending hanger as shown in Figure 47 is connected to a connecting rod which is disposed within the waUs of the drawer 56.

- the seal of the screw cap 1 2 extends and opens to the other side of the screw cap 152.
- the seal of the screw cap 152 has a gear on its outside surface but to allow the inside gear at the screw cap 152 to travel in a single direction, this seal is suspended inside di screw cap 152 and allows the screw cap 152 to travel/rotate around the seal in a single direction.
- the seal (the screw cap 152 seal inside the cap) remains stationary.
- the outside gear of the screw cap 152 turns/rotates or drives the screw cap 152 around its seal in a single direction.
- the driven gear of the cap, or the outside gear of the screw cap 152 moves the cap around its containing seal and the inside gear ⁇ f the screw cap 152 becomes the driving gear of its seal when caused to travel in opposite directions.
- the inside gear of the screw cap 152 and the gear outside its containing seal are for driving the rotation in opposite directions during rotation.
- the gear of the screw cap 152 can travel around the gear of the seal in a single direction. When its direction is reversed it catches the gear of the seal inside causing the seal to travel the same direction with the cap making the inside gear of the screw cap 152 die drive gear for its containing seal's gear (drive gear).
- the seal of the screw cap 152 has fitting space on the top side (connecting side).
- the fitting space is for the attached seal of the removable Uner 143 spout to fit into - when installed.
- the drive gear, its containing seal and the fitting space of the seal for the fitted attached seal of the removable liner's spout becomes the driving gear to twist or turn the spout of the removable liner 143, twisting it in, thereby tying the litter removable liner's spout by the attached seal of the litter spout inside the screw cap 152 fitted into its seal
- the gear (inside gear) of the cap is made to travel in the direction of the opposing gear of its containing seal, and it catches the gear, which then makes or causes the seal to travel in the same direction.
- the screw cap 152 is connecting or being screwed onto the passageway 146 it travels freely to connect with the passageway 146 because the direction of the gear of its containing seal is not opposing this movement.
