## Background
FIELD
This invention relates fixture cleaning and deodorizing devices, and specifically to a fixture cleaning device with a replaceable wick assembly and solution container.
BACKGROUND
Fixture cleaning and deodorizing devices are commonly utilized to address issues related to fixtures, such as toilets and urinals. These devices can include a liquid solution having one or more of deodorizers, cleaners, and fragrances. The solution is commonly provided via a supply tube from a container mounted to the device. The solution is pumped into a tube that passes the liquid solution either directly down an output tube or into a reservoir area. The solution then passes into a spurge pipe or other inlet) connected to the fixture. The device can also hang over the fixture and drip into or onto the fixture. When affixed to a fixture, flushing of the device pulls the solution into (through) the spurge pipe and ultimately to the fixture to mix with incoming water and liquid and/or solid waste in the fixture. The solution is provided at a predetermined or intermittent rate or during a flushing action. In some devices, a wick is provided at the reservoir to absorb the solution and position it to receive a greater exposure to airflow. Over time it is common for the wick to develop a layer of solidified/crystalized solution thereupon. Eventually, the solidified/crystalized solution limits the wick's ability to wick (capillary action) the solution and/or expose the solution to airflow and therefore the device begins to fail in its intended operation and can lead to overflowing of the reservoir area. Periodic maintenance of the wick is required to maintain acceptable operation. Such maintenance requires a person to physically engage the wick, which can often be overlooked, and to remove it, which is often a messy and unpleasant operation. If a wick is left unchanged long enough, the device may require servicing to operate properly again. As such, maintenance is unpleasant, and often these devices are not properly maintained.
Accordingly, it would be desirable to provide a fixture cleaning and deodorizing apparatus and method of use that overcomes at least some of these shortcomings.

FIG. 3 illustrates a bottom view of the apparatus 90 with primary and secondary output ports 110, 112, FIG. 4 illustrates a back view of the apparatus 90 further illustrating the side intake vents 114 and top intake vents 116, as well as various securing points 120 for securing the apparatus 90 to a structure, such as a wall. It is understood that alternative embodiments, such as when apparatus 90 contains a single output port 110 as in FIG. 1B, dispenser housing 102 can include side intake vents 114 and top intake vents 116 as described above.
Referring to FIGS. 5A and 5B, FIG. 5A illustrates an exploded perspective view of an exemplary container assembly 122 for use with the dispenser 100 of FIGS. 1A and 1B. FIG. 5B illustrates an assembled perspective view of the container assembly 122. As shown, the container assembly 122 includes a wick assembly 124, a solution container 126, and a pump valve assembly 128. The pump valve assembly 128 includes a pump 130, a fan assembly 240 (not shown), cap 132, and a container supply tube 134. The cap 132 secures the pump 130 to the solution container 126. The wick assembly 124 includes a neck mount portion 142 secured to a wick support structure 143. The neck mount portion 142 includes a passage 144 configured for receipt around a solution container neck 146. In the embodiment shown, neck mount portion has a circular aperture; however, neck mount portion may be any shape or structure to secure on container neck 146. Although not shown, other mechanisms can be provided in place of or in addition to the neck mount portion 142 to secure the wick assembly 124 to the solution container 126, such as an adhesive. The wick assembly 124 further includes one or more wicks, such as a primary wick 136 and a secondary wick 138, both secured to a wick mount 140, wherein the wick mount 140 is secured to the wick support structure 143. In at least some embodiments, the wick support structure 143 can be formed solely from the wicks 136, 138 themselves, thereby eliminating the need for an additional component. The wicks 136, 138 are shown as cylindrical with bottom portions 201, although other shapes can be provided, such as flat, rectangular, etc. The wick support structure 143 includes a plurality of interconnected structures, such as rigid or semi-rigid spacers 148, flexibly connected by hinges 150 to form a collapsible structure, such as an accordion-style folding structure. The spacers 148 are connected at a first end 152 to the neck mount portion 142 and at a second end 154 to the wick mount 140. Various portions of the wick assembly 124 are positioned at least partially in a rear channel 153 that extends vertically along the back of the solution container 126. The rear channel 153 includes a channel bottom portion 155 and side portions 157, which in sum, provide a path for directed movement of the spacers 148 and the wick mount 140. In addition, the side portions 157 of the rear channel 153 can include vertical rails 159 (FIG. 5B) that are positioned to support the wick mount 140 in the rear channel 153 to allow for vertical travel about the channel bottom portion 155, but to inhibit horizontal movement out away from the channel bottom portion 155. Although rails 159 are shown, other mechanisms such as tabs, channels, etc. can be utilized.
The solution container 126 is shaped and sized to fit inside the dispenser housing 102 with the housing cover 104 in a closed position, although other shapes and sized can be provided. The solution container 126 can include protrusions 156 and/or channels that are configured to matingly engage with mating channels or protrusions in the dispenser housing 102. In this regard, only a solution container 126 with matching channels and/protrusions can be installed in the dispenser housing 102. In addition, the mating channels and/protrusions can serve to secure the container assembly 122 to the dispenser housing 102. Further, the solution container can be formed from various types of materials, rigid, semi-rigid, and flexible, for example, a rigid wall plastic container, or a flexible plastic bag.
As seen in FIG. 5B, the spacers 148 are situated in an at least partially folded position in the container channel 153. When the container assembly 122 is installed in the dispenser housing 104, the spacers 148 are pushed into a flattened position, as discussed in greater detail below. FIG. 6 provides a view of the container assembly 122, wherein the unfolded positioning of the wick support structure 143 shown is representative of the positioning of the wick support structure 143 when the container assembly 122 is installed in the dispenser 100. More particularly, the spacers 148 have been unfolded into a flat position adjacent to the channel bottom portion 155 of the rear channel 153, thereby displacing in a downward direction the wick mount 140 along with the wicks 136, 138.
Referring now to FIG. 7, a top perspective view of the dispenser 100 with the housing cover 104 removed and without a reservoir installed is shown. As shown, the dispenser housing 102 includes an upper latch 170 for engaging a mating portion on the housing cover 104. A fan on/off switch 172 and a dipswitch panel 174 are utilized to configure solution dosing frequency and fan activation (discussed below). The dispenser housing 102 further includes a neck receiver 176 to receive the solution container neck 146 and to assist with proper positioning and securement of the container assembly 122 inside a dispenser chamber 178 of the dispenser 100. A pair of battery compartments 180 are provided on either side of the dispenser chamber 178, the chambers 178 formed at least in part by battery supports 182. Additional or alternate power sources can be utilized as well, such as a 120 VAC, using a step-down transformer (not shown) positioned in a modified space inside the dispenser 100. As discussed above, the solution container 126 can include protrusions 156 and/or channels that are configured to matingly engage with mating channels or protrusions in the dispenser housing 102. A valve stem connector 189 is provided that secures to the pump valve assembly 128 to receive solution from the solution container 126. Additionally, a housing supply tube 190 is provided that communicates solution, pumped from the container 126, through the housing and to an output port, such as the primary output port 110 and/or the secondary output port 112.
The dispenser 100 can be provided either with a direct output module 192 (FIG. 7) or a reservoir module 194 (FIG. 8). The direct output module 192 is configured to pass solution directly through the dispenser 100 as demanded. Such a configuration is utilized when the wick assembly 124 is not included to provide a source of fragrance for emission from the dispenser 100. When a purchaser of the product does not wish to capitalize on the wick assembly 124, they can purchase the dispenser 100 with the direct output module 192 along with a solution container 126 that lacks the wick assembly 124, and the system is ready to use, if a purchaser wishes to utilize the wick assembly 124 to provide a source of fragrance, they can easily remove the direct output module 192 and install the reservoir module 194 as seen in FIG. 8.
FIG. 8 illustrates another top perspective view of the dispenser 100 with the reservoir module 194 installed in place of the direct output module 192. When the reservoir module 194 is utilized, the housing supply tube 190 extends to a reservoir 196 formed in the reservoir module 194. Solution pumped from the container assembly 122 is received and collected in the reservoir 196. When switching the reservoir module 194 for the direct output module 192, or vice-versa, the operator only has to remove the housing supply tube 190 from one module and re-install in the other module.
The reservoir module 194 includes one or more wick inlets, such as a primary wick inlet 198 and a secondary wick inlet 200. The wick inlets 198, 200 receive a wick bottom portion 201 of the wicks 136, 138 therein when wick assembly 124 is in its unfolded position (FIG. 11). Ridges 212 force wick assembly 124 into its unfolded position. When the wick bottom portion 201 of the wicks 136, 138 are positioned in the wick inlets 198, 200 and the solution includes a fragrance component, the fragrance situated in the reservoir 196 is absorbed by the wicks and travels up the wicks 136, 138 to provide an increased surface area for dispersing/emanating the fragrance.
Referring now to FIG. 9, illustrated is a cross-sectional side view of the fixture cleaning and deodorizing apparatus 90 with the container assembly 122 removed from the dispenser 100. As the container assembly 122 is not installed in the dispenser 100, the wicks 136, 138 (along with the wick mount 140) remain in an upwards pre-installation position to allow clearance to install the container assembly 122. In addition, the spacers 148 remain in a partially folded position. FIG. 10 illustrates the fixture cleaning apparatus 90 with the container assembly 122 partially installed in the dispenser 100. As shown, the hinges 150 are in abutment with a front surface 210 of a pair of ridges 212 extending from the dispenser housing 102. The ridges 212 serve to push the spacers 148 into an unfolded position as the container assembly 122 is inserted into the dispenser chamber 178 of the dispenser 100. More particularly, with the spacers 148 sandwiched between the channel bottom portion 155 of the rear channel 153 and the front surface 210 of a pair of ridges 212, the wick mount 140 must move downwards to allow the spacers 148 to shift.
As further shown in FIGS. 9 and 10, a portion of the pump valve assembly 128 protrudes from cap assembly 132 to engage valve stem connector 189. In the exemplary embodiment shown, valve stern connector 189 is a female element configured to receive the portion of the pump valve assembly 128 protruding from the cap assembly 132. Similarly, housing supply tube 190 is secured to valve stern connector 189 opposite pump valve assembly. Valve stern connector 189 includes a male component which inserts into the housing supply tube 190. The valve stem connector therefore creates a fluid tight seal between the pump valve assembly 128 and the housing supply tube 190 and puts the pump 130 in operable connection with the housing supply tube 190. In further embodiments, the pump valve assembly 128 (and therefore pump 130 and container supply tube 134) may be connected to the housing supply tube 190 using additional structures, including, but not limited to, friction-fit connectors, male-female connectors, clasps, and other structures known in the art.
FIG. 11 illustrates the fixture cleaning apparatus 90 with the container assembly 122 fully installed in the dispenser 100. As shown, the spacers 148 have been pushed flat against the channel bottom portion 155 of the rear channel 153 and the wick mount 140 has shifted downwards along with the wicks 136, 138 such that the wick bottom portion 201 of the wicks 136, 138 are positioned in the primary wick inlet 198 and secondary wick inlet 200. In addition, pushing the solution container 126 in place causes an abutment of the solution container 126 with a reset switch 220 to communicate to a processor (not shown) mounted on a printed circuit board 221, that a refill has been installed. FIG. 12 illustrates the fixture cleaning and deodorizing apparatus 90 with the housing cover 104 installed and fan assembly 240 visible. Using close tolerances, the ability to close the housing cover 104 properly can be used as an indication that the container assembly 122 has been fully installed in the dispenser 100, since without a full flattening of the spacers 148 extra space between the channel bottom portion 155 of the rear channel 153 would exist.
Removal of the container assembly 122 also removes the complete wick assembly 124 with the wicks 136, 138 intact, thereby eliminating the hassle and mess of separately removing the wicks and ensuring that the wicks are replaced with each refill of solution to prevent failure inducing degradation and potential overflowing of reservoir 196. In this regard, the overall reliability, longevity, and effectiveness of the fixture cleaning and deodorizing apparatus 90 is substantially enhanced. As noted, the container assembly 122 need not include the wick assembly 124.
FIG. 13 illustrates a front view of the fixture cleaning apparatus 90 with the housing cover 104 removed, showing the valve stem connector 189 secured to the pump valve assembly 128. The valve stem connector 189 is configured to receive force from a hammer 232, which depresses the valve stem connector 189 and subsequently actuates the pump valve assembly 128, thereby pumping solution from the solution container 126 through the valve stem connector 189 and into the housing supply tube 190. Gear cover 234 is covering gears 236. FIG. 14 illustrates a front view of the apparatus 90 with the housing cover 104 and gear cover 234 (FIG. 13) removed. The hammer 232 is driven by one or more gears 236, which are powered by an electric motor 238 (FIG. 15). Actuation of the motor 238 results in rotation of the hammer 232.
Although a wick-containing reservoir system can provide a suitable fragrance distribution system, a fan assembly 240 can be provided, such as a squirrel-cage fan assembly, to enhance emanation/dispersion of fragrance from the wicks 136, 138, FIG. 15 illustrates a cross-section rear view of the apparatus 90 taken at line 15-15 of FIG. 2. As seen in FIG. 15, a fan cover 242 is provided to seal one side of a fan blade chamber 244 (FIG. 16). Referring to FIG. 16, provided is a cross-section rear view of the apparatus 90 taken at line 16-16 of FIG. 2 with the fan cover 242 removed for clarity. When activated, the fan assembly 240 pulls fresh air through the side intake vents 114 and top intake vents 116. The fresh air 243 is pushed through the fan blade chamber 244 (FIG. 17) and downwards into a fan passage 246 (Ha 17) that includes various portions of the fixture cleaning and deodorizing apparatus 90, such as, an inner back portion 247 (FIG. 17) of the dispenser housing 102, the rear channel 153, the solution container 126, and the housing cover 104. As the fresh air 243 is directed past the wicks 136, 138 and the reservoir 196, the scent of the solution is forced out of the fixture cleaning apparatus 90 as scented air 245 and into the room that the apparatus 90 occupies. Use of the fan assembly 240 in this regard allows for enhanced dispersion of scent. FIG. 17 illustrates a partial cross-sectional side view of the apparatus 90, taken along line 17-17 of FIG. 1A. FIG. 17 further illustrates the path of the fresh air 243 through the fixture cleaning apparatus 90.

In alternative embodiments, dispenser 100′ with integrated pump valve assembly 128′ can include a direct output module 192 in place of reservoir module 194, as discussed with reference to FIGS. 7 and 8.
it is to be appreciated that removing gear cover 234′ not only provides access to gears 236′, but also pump valve assembly 128′ for repair work. It is to be further understood and appreciated that pump valve assembly 128′ may be fully removed from fixture cleaning and deodorizing dispenser 100′, as illustrated in FIGS. 20A and 20B, for repair or to be replaced.
FIG. 20A illustrates and exemplary pump valve assembly 128′ in further detail and removed from fixture cleaning and deodorizing dispenser 100′, and FIG. 20B is a cross-sectional view of the pump valve assembly 128′ of FIG. 20A. As illustrated, pump 130′ is connected to container supply tube 134′ by way of valve stem connector 189′ and pumps solution from container 126′ to metered pump element 312′. O-ring grooves 131′ are disposed between valve stem connector 189′ and pump 130′ and are configured to accept and secure O-rings which provide a seal when valve stem connector 189′ engages a solution container 126′ (not shown). In some embodiments, the o-rings create a fluid tight seal in the container neck 146′. In further exemplary embodiments, the o-rings create an airtight seal. It is to be understood that a single o-ring may be used and other structures may be used alone or in conjunction with the O-rings to create seal, including, but not limited to, gaskets, physical contours, interlocking components, and other structures known in the art.
Metered pump element 312′ stores solution when transfer tube 330′ is closed, such as by ball valve 319′. Piston 320′, on opposite end of metered pump element 312′ from ball valve 319′, is configured to be activated by hammer 232′.
As shown in FIGS. 20A and 20B, transfer tube 315′ is closed by ball valve 319′ when piston 320′ is in the out position. When piston 320′ is actuated by hammer 232′ to the in position (not shown), solution from metered pump element 312′ is forced down transfer tube 330′ and ball valve 319′ is forced to an open position. Housing supply tube connection 315′ is configured to connect to housing supply tube 190′ (not shown). Solution then proceeds through transfer tube 330′ and into housing supply tube 190′ (not shown), which transfers the solution to the reservoir module 194 (not shown).
As illustrated in FIGS. 20A and 20B, metered pump element 312′ is a metered pump area operably connected with the pump 130′, piston 320′ and housing supply tube connection 315′. The pump 130′ is configured or programmed to pump a metered amount of solution from container 126′ to the metered pump element 312′. In further exemplary embodiments, metered pump element 312′ may be an independent physical structure.
In the exemplary embodiment shown, housing supply tube connection 315′ is a male feature onto which the housing supply tube 190′ (not shown) is connected. Housing supply tube connection 315′ and housing supply tube 190′ (not shown) remain connected by friction, but in further exemplary embodiments, may be joined using additional structures, including but not limited to, male-female connectors, clasps, and other structures known in the art.
FIG. 21 illustrates a cross-sectional view of dispenser 100′ and container assembly 122′ with container assembly 122′ ready to install in dispenser 100′. As container assembly 122′ is not installed in dispenser 100′, wicks 136 (not shown), 138 remain in an upwards pre-installation position with spacers 148 partially folded. Valve stem connector 189′ with pump 130′ are angled to meet tube cap 132b′. Cap 132a′ includes optional integrated seal 132c′, which is covering the aperture in cap 132a′. 
FIG. 22 illustrates the cross-sectional view of FIG. 21 with container assembly 122′ partially installed in dispenser 100′. As shown, male valve stem connector 189′ with pump 130′ engages the inner surface of female tube cap 132b′, and valve stem connector 189′ has ruptured seal 132c′ of cap 132a′. O-rings which sit in O-ring grooves 131′ (not shown) have a diameter corresponding to the inner diameter of tube cap 132b′ and thereby creates a seal at container neck 146′.
As container assembly 122′ continues to a fully installed position and is secured in dispenser 100′, wick assembly 124 is forced into an expanded position such that spacers 148 are sandwiched between the channel bottom portion 155 of the rear channel 153 and front surface 210 of a pair of ridges 212, and the wick mount 140 with wicks 136, 138 is forced downward such that wicks 136, 138 are exposed to solution in reservoir module 194. This movement is described in detail with reference to FIGS. 9-11, above.
FIG. 23A illustrates a front cross-sectional view of the fixture cleaning and deodorizing apparatus 90′ with the housing cover 104′ and gear cover 234′ removed and container assembly 120′ fully installed. FIG. 23B illustrates a front cross-sectional view of the fixture cleaning and deodorizing apparatus 90′ with the housing cover 104′ and gear cover 234′ removed, as well as a cross-sectional view of the fully installed container assembly 120′ of FIG. 23A.
As illustrated in FIG. 23A, piston 320′ is in the “out” position, meaning solution from solution container 126′ is currently stored in metered pump element 312′. FIG. 23B shows piston 320′ in the “in” position, meaning the hammer 232′ has been activated and solution which was previously stored in the metered pump element 312′ has been forced through transfer tube 330′ and to housing supply tube 190′ (not shown) via housing tube connection 315′.
As shown in FIG. 23B, pump 130′ goes into container 126′, and more specifically tube cap 132b′, when container assembly 122′ is secured in dispenser chamber 178′.
FIG. 23B also shows pump valve assembly 128′ in more detail with gears 236′ and hammer 232′. The hammer 232′ is driven by one or more gears 236′, which are powered by an electric motor 238′ as shown in FIG. 24. Actuation of the motor 238′ results in rotation of the hammer 232′, which ultimately forces solution into housing supply tube 190′
FIG. 24 is a cross-sectional rear view of the apparatus 90′ showing fan assembly 240′ and motor 238′. As seen in FIG. 24, a fan cover 242′ is provided to seal fan blade chamber 244′ (not shown), as summarized below and described fully with reference to FIG. 15.
As described above, when activated, fan assembly 240′ pulls fresh air through the side intake vents 114 and top intake vents 116 (not shown). The fresh air is pushed through the fane blade chamber 244′ and into fan passage 246′ (not shown). As the fresh air is directed past the wicks 136, 138 (not shown) and reservoir module 194 (not shown), the scent of the solution is forced out of fixture cleaning and deodorizing apparatus 90′ and into the room the apparatus 90′ occupies.
FIG. 25 illustrates a view of the fixture cleaning and deodorizing apparatus 90 with only a single output port 250, which is connected to piping for a toilet/urinal. More particularly, the output port 250 is connected to an output line 252, which is connected to a spurge pipe 254 via a saddle valve 256. An auto-flush valve 258 is shown that controls the flow of the water from the supply pipe 260 into the spurge pipe 254. Flushing of the fixture creates a drop in pressure in the output line 252, which allows a metered amount of solution to be released into the output line 252, as solution already present in the output line 252 is pulled into the spurge pipe via suction created at the spurge pipe 254. It is to be understood that the apparatus 90 need not be connected to a spurge pipe 254, it can be connected to other water supply piping or the directly to the fixture itself, including being supported adjacent to the fixture to provide the solution via gravity feed.
In use, when a solution container 126 is empty as indicated by the indicators 106, the housing cover 104 is lifted and the container assembly 122 is removed from the dispenser 100. A new container assembly 122 is installed in the dispenser chamber 178 of the dispenser 100 and the lid is closed. Installation of the new container assembly 122 pushes the reset switch 220, which communicates to the processor that a new container assembly 122 has been installed. The spacers 148 and/or hinges 150 are pushed against the ridges 212 to flatten the spacers 148 and push the wick mount downwards, inserting the bottom portions 201 of the wicks 136, 138 into the wick inlets 198, 200.
Dispersion of the solution from the apparatus 90 can occur based on a number of criteria, such as scheduled time, a dark room sensed, a flush sensed, etc. These criteria are provided and managed by the dipswitch panel 174 on the printed circuit board 221. When the fixture cleaning and deodorizing apparatus 90 is activated to disperse the solution, the processor activates the hammer 232 to push down the valve stem connector 189 on the pump valve assembly 128. Actuation of the pump valve assembly 128 pumps solution through the container supply tube 134 and into the housing supply tube 190. At the same time, solution that was in the housing supply tube 190 is pumped into the reservoir 196. Further, solution that resided in the reservoir 196 is pulled through an outlet port (110, 112, 250), which is connected to an output line (252), which is connected to a spurge pipe 254. Finally, the solution in the spurge pipe 254 is pulled into the fixture. Although some fragrance (when included in the solution) will emanate from the solution, as the solution enters and is processed by the fixture, the majority of emanation will come from the wicks 136, 138. As noted above, when a fan assembly 240 is provided, the fan can be activated by a flushing of the fixture or on a scheduled basis or sensed basis. As the wicks 136, 138 are continuously soaked with solution (with fragrance), the fan assembly 240 can be operated at any time to emanate a scent from the fixture cleaning apparatus 90.
In at least some embodiments, the fixture cleaning and deodorizing apparatus 90 can be utilized solely as an air freshener/deodorizer. As such the output ports 110, 122 can be plugged or otherwise non-existent. The solution would include only a fragrance and/or deodorizer that is delivered to a reservoir similar to reservoir 196 and absorbed by one or more wicks, such as wicks 136, 138. By utilizing the fan assembly 240, the apparatus 90 can provide a sufficient airflow to function as an air freshener/deodorizer.
The shape and size of the aforementioned components can be modified to accommodate installation space requirements, desired level of solution processing and fragrance emanation, etc. In addition, the described location of components of the fixture cleaning and deodorizing apparatus 90 can be modified to accommodate various shapes and sizes of the fixture cleaning and deodorizing apparatus 90 and/or to improve efficiency. The spacers 148 can be formed from various materials, such as a wick material or plastic that is configured in any of numerous shapes and sizes. The wicks 136, 138 can be secured to the wick mount in any one of numerous ways, such as protruding rings 125 (FIG. 5B) that allow for insertion of the wicks 136, 138 in a vertical orientation. Also, when a single wick is used, the wick mount can be modified to provide a centered mounting point for the wick.
If the solution container 126 is a liner/bag, can affix the wicks 136, 138 to the solution container 126 (tape, glue, etc.) on a back side of the solution container 126. The male plastic features (similar to parts 212 on FIG. 10) can push in the flexible bag accordingly (with the closer of the main cover 104) and therefore, also push down the wicks 136, 138 into place in the reservoir.
Additionally, the spacer 148, hinge 150, and wick mount 140 configuration used to shift the wicks into the wick inlets 198, 200 can be replaced with other configurations, such as a flexible arc-shaped rod that is secured to an upper portion of the rear channel 153 and a wick holder at a lower portion of the rear channel 153, wherein the arc of the rod is collapsed when abutted with the ridges 212 or the dispenser housing 102, to push the wick holder downwards. Further, the components can be substituted with other components that perform a similar function, such as a different style of fan.
While FIG. 25 is described in reference to the fixture cleaning and deodorizing apparatus 90, it is to be understood that the apparatus 90 may be replaced with the alternative fixture cleaning and deodorizing apparatus 90′.
