Referring now to the drawings, FIGS. 1-6 illustrate an embodiment of a decontamination device 100. Referring first to FIGS. 1 to 4, the decontamination device 100 may include a housing 102 forming a handle portion 104, a main body portion 108, and a nozzle portion 110. The main body portion 108 may include a bottom portion 107, a top portion 109, a front portion 111, and a rear portion 113. The handle portion 104 may include a front handle arm 112 extending from the top portion 109 near the main portion 108 of the front portion 111 and a rear handle arm 114 extending from the top portion near the rear portion 113, and the front handle arm and the rear A handle 105 extends between the distal ends of the handle arms. A handle gap 116 may be formed in a space between the top portion 109 of the main body portion 108, the front handle arm 112, the rear handle arm 114, and the handle 105. In the illustrated embodiment, the trigger 106 may be disposed on the handle 105 near the front handle arm 112 to access the trigger via the handle gap 116 by the user holding the decontamination device 100 by the handle. When activated, the trigger 106 may be pressed into the handle 105. However, it should be understood that, in other embodiments, the trigger 106 may be set in different configurations.

In the embodiments shown in FIGS. 1 to 4, the nozzle portion 110 may be disposed on the front portion 111 of the main body portion 108 near the top portion 109. The nozzle portion 110 may include a removable pull safety device 118 configured to at least temporarily close the final nozzle 120 (visible in FIG. 5). The pull safety device 118 and its engagement with the decontamination device 100 can be best understood by comparing FIGS. 1 and 5, which shows an embodiment of the device that pulls the safety device in place, and FIG. 5 shows the pull An embodiment of a device with a safety device removed. The pull safety device 118 may include a pull tab 122, a central cover 124, and a tail 126. When located on the nozzle portion 110, the central cover 124 may engage the nozzle face 125 and fit within the nozzle ring 127 to close the final nozzle 120. In some embodiments, the central cover 124 may have at least a slight interference fit with the nozzle ring 127 such that the pulling safety device remains in place until it is pulled by the user. In some embodiments, the tail portion 126 may fit within a tail slot 128 formed in the front handle arm 112. At the end of the tail slot 128 spaced away from the nozzle portion 110, a tip aperture 130 may also be formed in the front handle arm 112. In some embodiments, the tail tip 132 may fit into the tip aperture 130, as discussed in more detail below. In one embodiment of the decontamination device 100, the pull safety device 118 may be removed by a user by pulling the pull tab 122 away from the nozzle portion 110 before dispensing fluid from the device. FIG. 6 shows another view of the decontamination device 100 with the pulling safety device 118 removed. In some embodiments, the pull security device 118 may include a tamper-resistant system for removal. For example, a finger or accessory connected to the pull safety device may help removably secure the pull safety device 118 to the decontamination device 100. When the pull safety device 118 is removed from the nozzle portion 110, the fingers may deform, making it difficult or impossible to put the pull safety device back on the nozzle portion. This system can prevent the pull safety device 118 from being placed back on the already used device, and therefore cannot accommodate a sufficient supply of material in its tank. An exemplary embodiment of such a system is explained below with reference to FIG. 17. Other safety device embodiments as an alternative to the illustrated pull safety device are also considered herein. For example, some embodiments may include pins that are inserted into one or more locations on the decontamination device 100, which may mechanically or otherwise prevent or limit the movement of the trigger 106, cam member 162, mixing manifold 146, or other components The result may be preventing the mixing or dispensing of materials.

7 and 8 show an embodiment of a decontamination device 100 having a spray selector switch 134 formed on the nozzle face 125, which spray selector switch may be in a first position 136 (shown in FIG. 7) and Move between second positions 138 (shown in FIG. 8). As shown in FIGS. 7 and 8, the nozzle portion 110 may include a nozzle ring 127 that at least partially surrounds the nozzle face 125 and a final nozzle 120 formed through the nozzle face. The spray selector switch 134 may be disposed between both ends of the nozzle ring 127. In some embodiments, the nozzle face 125 may be rotated relative to the nozzle ring 127 such that the nozzle face is rotated when the spray selector switch 134 is moved from the first position 136 to the second position 138. In such an embodiment, when the spray selector switch 134 is moved, the shape or flow rate of the spray when the fluid is dispensed through the final nozzle 120 may be changed. For example, in some embodiments, the first spray mode may be obtained by the spray selector switch 134 in the first position 136 as shown in FIG. 7, and the second spray mode may be obtained by the spray selector switch in the first position 136 as shown in FIG. 7. Get in the second position 138. Examples of spray patterns that can be generated by the first or second position of the spray selector switch include, but are not limited to: directional wet cone, directional wet vertical spray, directional wet horizontal spray, wide jet, direct jet, or allow custom spray Other configurations covered. Moreover, although the embodiment shown in FIGS. 7 and 8 shows two spray selector switch positions, it is contemplated herein that the spray selector switch may have any number of positions to indicate any number of user-selectable Spray mode. It is also contemplated that in some embodiments, the spray selector switch may not be fixed to the nozzle face, but may be moved along the nozzle face and move other components within the nozzle section and affect the spray shape.

9 and 10 show an embodiment of the decontamination device 100 in which a part of the housing 102 is removed to show the components housed in the housing. In the embodiment shown in these figures, the main body portion 108 houses the first tank 140, the second tank 142, and the third tank 144 in the housing 102. Although the embodiment shown herein shows an embodiment of a decontamination device 100 equipped with three tanks, other embodiments with different numbers of tanks, such as two or more than three, are also contemplated herein. Further, it is contemplated that in various embodiments, the tank may be of various types, such as, for example, an aerosol, a valve on a bag, or other techniques known to those skilled in the art. Alternatively, other distribution designs or mechanisms may be used in other embodiments. For example, some embodiments may include a preloaded syringe or insert dry and / or erodible material into the mixing manifold 146. In some embodiments, each tank 140, 142, 144 may be connected to a mixing manifold 146 that may be received in a top portion 109 of the body portion 108. In general, each tank 140, 142, 144 may contain material inside thereof to mix within the mixing manifold 146 when the trigger 106 is activated and dispense through the final nozzle 120 of the nozzle portion 110. The material held inside each tank can vary depending on the embodiment and depending on the desired application. Some non-exhaustive examples of materials that can be contained in a tank are quaternary ammonium compounds, benzyl-C12-C16 alkyl dimethyl chloride, liquid hydrogen peroxide, and diacetin. In some embodiments, one tank can hold water with a quaternary ammonium compound held at about 120 pounds per square inch (psi), and the other tank can hold a 7.99% hydrogen peroxide solution that is unstable at about 120 psi, And another jar can hold food grade diacetin. However, those skilled in the art will understand that in different embodiments, different combinations of different materials may be retained in the tank.

9 and 10 also show other components of the trigger 106. Specifically, the trigger 106 may include a first trigger arm 148 substantially received within the handle 105 and a second trigger arm 150 substantially received within the rear handle arm 114. The first trigger arm 148 and the second trigger arm 150 may meet at a pivot portion 152, which may include a pivot aperture 154 for receiving a pivot fastener 156. The pivot fastener 156 may be any type of fastener suitable for securing the trigger to the housing 102 through the pivot aperture 154 and allows the trigger 106 to pivot about the pivot fastener 156 about the pivot portion 152. In some embodiments, the pivot fastener 156 may be integrated with the housing 102 of the decontamination device 100. The trigger 106 may further include a trigger input 158 provided at a distal end 149 of the first trigger arm 148 and a trigger output 160 provided at a distal end of the second trigger arm 150. A trigger input 158 may extend from the handle 105 into the handle gap 116 so that a user holding the decontamination device 100 can reach it. When the user depresses the trigger input 158, the trigger 106 can pivot about the pivot fastener 156, thereby converting the basic vertical motion of the trigger into a substantially horizontal or lateral motion of the trigger output 160.

Although the embodiment shown in FIGS. 9 and 10 includes a pivot trigger, other contemplated embodiments may include a link or cable and pulley system used as a cam, which itself may take the form of a variety of configurations. In addition, the influence of the trigger on the injection duration may vary in different embodiments or combinations of different embodiments. For example, in some embodiments, the decontamination device 100 may be configured to mix and dispense material only when the trigger 106 is actively depressed, and stop dispensing when the user releases the trigger. In other embodiments, the decontamination device 100 may be configured to begin mixing and dispensing when the trigger 106 is activated, and continue mixing and dispensing until the tank is emptied, regardless of whether the trigger remains depressed. In other embodiments, the trigger 106 may include a spray lock that locks the trigger in a depressed position.

In some embodiments, the top portion 109 of the body portion 108 may additionally receive a cam member 162 that can be engaged with the mixing manifold 146. The cam member 162 may have a trigger end 164 and a spring end 166 opposite the trigger end. The cam member 162 may be moved along a first axis 210, and in some embodiments, the first axis 210 may be substantially horizontal or lateral with respect to the mixing manifold 146 between the trigger output 160 and the nozzle portion 110. In some embodiments, the spring 168 may be engaged with the cam member 162 to bias the cam member away from the nozzle portion 110 and toward the trigger output 160. In some embodiments, and as shown in FIG. 15, the spring end 166 of the cam member 162 may concentrically surround the member lever 169 of the cam member. The spring 168 may abut a biasing lever 159, which may be anchored to the housing 102. Thus, when the user depresses the trigger input 158, the trigger output 160 may move substantially along the first axis 210, against the trigger end 164 of the cam member 162, which in some embodiments It's basically horizontal. If the trigger input 158 is depressed with sufficient force to overcome the biasing force of the spring 168, the cam member 162 may move relative to the mixing manifold 146 in a direction toward the nozzle portion 110. In addition, in some embodiments, the trigger may be configured as a palm squeeze configuration, where, for example, the palm of a user may press the trigger to enable a mechanism to activate the tank. In another embodiment, the trigger may be a thumb press configuration that can utilize an internal mechanism to activate the tank.

11 to 13 show enlarged views of an embodiment of the handle portion 104 and the top portion 109 of the main body portion 108, with the portion of the housing 102 removed for clarity. Referring first to FIG. 13, the cam member 162 and the mixing manifold 146 may be oriented relative to each other such that at least one cam surface may translate movement of the cam member along the first axis 210 into movement of the mixing manifold along the second axis 215, the The second axis may be substantially perpendicular to the first axis in some, but not all embodiments. In some embodiments, the first axis 210 may be a substantially horizontal axis, and the second axis 215 may be a substantially vertical axis. In such embodiments, the substantially horizontal movement of the cam member may be converted into a substantially vertical movement of the mixing manifold. Specifically, in some embodiments, the cam member 162 may have a first cam surface 170, a second cam surface 172, and a third cam surface 174, and the mixing manifold 146 may have a first follower 171, a second follower The member 173 and the third follower 175 are engaged with the first cam surface, the second cam surface, and the third cam surface, respectively. When the trigger output 160 pushes the cam member 162 toward the nozzle portion 110, the first cam surface 170, the second cam surface 172, and the third cam surface 174 may abut the first follower 171 and the second follower 173, respectively. And the third follower 175 slides. Since the mixing manifold 146 is substantially limited or restricted in horizontal movement, the movement of the cam surface against the follower of the mixing manifold exerts a vertical downward force on the mixing manifold. As a result, the mixing manifold 146 can be moved vertically downward from the passive position toward the first tank 140, the second tank 142, and the third tank 144 to the dispensing position. The cam and follower relationship between the cam member 162 and the hybrid manifold 146 is also shown in cross section in FIG. 14. Although the embodiment shown here shows three corresponding cam surfaces and followers, embodiments of the cam member and the hybrid manifold have more or fewer corresponding cam surfaces and followers. In some embodiments, the number of cam surfaces and corresponding followers may correspond to the number of cans used in a particular device. For example, a device that accommodates two tanks may include a cam member with two cams and a hybrid manifold with two corresponding followers. In addition, in some embodiments, the cam member may be integrated into the trigger itself.

In some embodiments, the vertical downward movement of the mixing manifold 146 may open the first valve 176, the second valve 178, and the third valve 180 between the first tank 140, the second tank 142, and the third tank 144, respectively. Each, thereby releasing the contents of the tank into the mixing manifold. The first tank 140, the second tank 142, and the third tank 144 are best shown in FIG. 14, and their respective first valve 176, second valve 178, third valve 180, and mixing manifold 146 interaction. FIG. 14 shows a cross-sectional view of one embodiment of the decontamination device 100, focusing on the top portion 109, and the interaction of the valve, tank, and mixing manifold. The embodiment shown in FIG. 14 includes different types of valves for the first valve 176, the second valve 178, and the third valve 180. In this embodiment, each of the first, second, and third valves 176, 178, 180 may include a direct connection to the mixing manifold 146, with integrated nozzles in the manifold. However, it is contemplated that other types of connections may be used in other embodiments. For example, the connection between the first tank 140, the second tank 142, the third tank 144, and the mixing manifold 146 may include a male nozzle on the top of the tank that may be pressed into a gland on the mixing manifold. Either the contact seal or the male nozzle can be pressed into the receiving cone on the mixing manifold or other connections known to those skilled in the art.

In the embodiment of FIG. 14, the mixing manifold 146 may be substantially hollow so as to form a mixing chamber 182 within the mixing manifold. The mixing chamber 182 may extend substantially the entire length of the mixing manifold 146 from the nozzle portion 110 to a chamber lid 184 that seals the mixing chamber opposite the nozzle portion. In addition, a chamber insert 186 may be disposed within the mixing chamber 182 to be substantially surrounded by the mixing manifold 146. The size and shape of the chamber insert 186 may affect the volume and flow pattern within the mixing chamber 182. For example, a larger chamber insert may result in a smaller mixing chamber volume, and a smaller chamber insert may result in a larger mixing chamber volume. The size and shape of the mixing chamber 182 may affect the flow pattern and mixing quality of the various materials of the first tank 140, the second tank 142, and the third tank 144 as they flow through the mixing chamber and eventually flow out of the nozzle portion 110.

In the embodiment shown in FIG. 14, each of the first valve 176, the second valve 178, and the third valve 180 has a stem portion and a valve hole formed through the stem portion, so that when the valve is in the open position, Fluid communication is provided between each respective first tank 140, second tank 142, third tank 144, and mixing chamber 182. Specifically, when the trigger 106 is activated, the trigger output 160 horizontally moves the cam member 162 and presses the first cam surface 170, the second cam surface 172, and the third cam surface 174 against the first follower. 171, the second follower 173, and the third follower 175. The mixing manifold 146 is pressed vertically downward. The downward vertical movement of the mixing manifold 146 causes the valve stem portion to move downward while moving the first valve 176, the second valve 178, and the third valve 180 to the open position. When all of the first valve 176, the second valve 178, and the third valve 180 are moved to the open position at the same time, the contents of the first tank 140, the second tank 142, and the third tank 144 may enter the mixing chamber 182 at substantially the same time to Allow mixing.

The first tank 140, the second tank 142, and the third tank 144 may be disposed within the housing 102 of the decontamination apparatus 100 and arranged such that the upper portion of the tank may be engaged with a corresponding valve. Specifically, the upper part 151 of the first tank 140 may be provided to be engaged with the first valve 176, the upper part of the second tank 142 may be provided to be engaged with the second valve 178, and the third tank 144 may be provided to be engaged with the third The valve 180 is engaged. The first valve 176 may have a first stem portion 188 having a first valve hole 189 formed through the first stem portion. The first valve hole 189 may provide a first tank 140 and a mixing chamber 182. Fluid communication. The second valve 178 may have a second stem portion 190 having a second valve hole 191 formed through the second stem portion, and the second valve hole 191 may provide between the second tank 142 and the mixing chamber 182 Fluid communication. The third valve 180 may have a third stem portion 192 having a third valve hole 193 formed through the third stem portion. The third valve hole 193 may provide a third tank 144 and a mixing chamber 182. Fluid communication. In some embodiments, the upper portions 151, 153, 155 of each respective first tank 140, second tank 142, third tank 144 may form a valve orifice 194, 195, 196 or other inlet to receive or otherwise Engage each respective first valve 176, second valve 178, third valve 180.

The size of each valve hole can vary from valve to valve and depends on the desired quality of the mixture. For example, in the embodiment shown in FIG. 14, the first valve hole 189 formed through the first rod portion 188 may be relatively narrow compared with the second valve hole 191 formed through the second rod portion 190. This relationship may be desirable where the mixture dispensed by the decontamination device 100 has a higher volume of material stored in the second tank 142 than the material stored in the first tank 140. As another example, the third valve 180 shown in FIG. 14 may include a restrictor orifice because the third valve hole 193 formed through the third stem portion 192 is narrowed near the mixing chamber 182. However, it should be understood that any of these types of valve holes and others can be used in any combination to affect the mixture dispensed from the decontamination device 100. It should also be understood that other types of device components may be used to control the proportion of material entering the mixing chamber 182 from the tank and the amount of material flowing out of the final nozzle 120. For example, other embodiments may include induced eddy currents, pressure-regulated orifices, resistance orifices, and the like. These components and features described herein can add control over the proportion of mixed materials on a mass or volume basis, because in some embodiments, the material dispensed can rely on strict control of the percentage of mixing.

FIG. 14 also illustrates the relationship between the mixing manifold 146, the chamber insert 186, and the nozzle face 125. The nozzle end 197 of the chamber insert 186 and the nozzle end 198 of the mixing manifold 146 may engage the nozzle face 125 to form a flow path between the mixing chamber 182 and the final nozzle 120. The nozzle face 125 may include a generally cylindrical outer nozzle collar 121 that may receive the nozzle end 198 of the mixing manifold 146. The nozzle face 125 may also include an internal nozzle collar 123 that is substantially concentric with the external nozzle collar 121, and the internal nozzle collar 123 may receive the nozzle end 197 of the chamber insert 186. In the embodiment shown in FIG. 14, the mixing space 129 may be formed in the outer nozzle collar 121 and the nozzle end 198 of the mixing manifold 146 that may be in fluid communication with the mixing chamber 182. Additionally, although the inner nozzle collar 123 may substantially surround the nozzle end 197 of the chamber insert 186, it should be understood that at least a portion of the inner nozzle collar may allow fluid communication between the mixing space 129 and the final nozzle 120. However, in some embodiments, the engagement between the nozzle end 197 of the chamber insert 186 and the internal nozzle collar 123 may at least slightly restrict the flow between the mixing space 129 and the final nozzle 120. In some embodiments, this restriction may allow material released from the first tank 140, the second tank 142, and the third tank 144 to flow through the mixing chamber 182 and improve within the mixing space 129 as it converges in the mixing space 129 the mix of. In other words, in some embodiments, the material released from the tank closest to the nozzle portion 110 (e.g., the third tank 144) may be from a tank further away from the nozzle portion (e.g., the first tank 140 or the second tank 142) The released material reaches the mixing space 129 before, and the restrictive engagement between the nozzle end 197 of the chamber insert 186 and the internal nozzle collar 123 of the nozzle face 125 can slow down the dispersion of the material, allowing it to be sprayed from the final nozzle 120 Opportunity for more thorough mixing. Another view of the relationship between the mixing manifold 146, the chamber insert 186, and the nozzle face 125 is also shown in FIG. 15, with the pull safety device 118 located above the nozzle face 125.

Therefore, in the embodiment shown in FIGS. 14 and 15, when the user activates the trigger 106, the material stored in the corresponding first tank 140, second tank 142, and third tank 144 can be released to The mixing chamber 182 flows into the mixing space 129 and flows out as a mixture through the final nozzle 120.

Figures 16 and 17 show the relationship between the pull safety device 118 and the trigger 106. In some embodiments, pulling the safety device 118 prevents activation of the trigger 106 when in place. Specifically, the tail 126 of the pulling safety device 118 may include a tail tip 132 that may fit through a tip aperture 130 formed in the front handle arm 112 to engage the distal end 149 of the first trigger arm 148. In some embodiments, a safety hole 147 may be formed in the distal end 149 of the first trigger arm 148 to receive the tail tip 132. In such an embodiment, the tail tip 132 may prevent the first trigger arm 148 from moving when a user applies pressure to the trigger input 158. This safety mechanism can prevent accidental or unintentional activation and distribution of materials stored in the decontamination device 100. However, when the user wants to use the decontamination device 100, the user can remove the pull safety device 118, for example, by pulling the pull tab 122. Pulling the pull tab 122 can remove the central cover 124 from its position above the nozzle face 125 and further remove the tail tip 132 from the safety hole 147 in the trigger. This embodiment of the pull safety device 118 and trigger 106 can help prevent improper activation of the device, as the pull safety device can be configured so that the tail tip 132 cannot be removed from the safety hole 147 and the tip aperture 130 until the center The cover 124 has been pulled away from the final nozzle 120. However, in other embodiments, it is contemplated that the tail tip 132 and the central cover 124 may be removed separately.

In some embodiments, as best shown in FIG. 17, the tail tip 132 may include at least one finger 133, and each finger 133 may further include a finger protrusion 135. In such an embodiment, the safety hole 147 may be formed to be relatively wider near its end compared to its entrance so as to accommodate the finger protrusion 135 when the tail tip 132 is in place within the safety hole. A gap may be formed between the fingers 133 such that when the tail tip 132 is removed from the safety hole, the inclined wall of the safety hole 147 abuts on the finger protrusion 135, forcing the distal end of the finger 133 inward. This inward movement of the fingers 133 may allow the tail tip 132 to be removed from the safety hole 147 when the user pulls with sufficient force to overcome the tendency of the fingers to resist inward movement. In some embodiments, the elasticity of the fingers 133 may force the distal end to return to the original expanded position once the tail tip 132 is completely disengaged from the safety hole 147. In such an embodiment, the fingers 133 may be expanded to a width greater than the width of the entrance of the security hole 147, thereby preventing or limiting the ability to re-insert the tail tip 132 into the security hole. In such an embodiment, a potential user of the decontamination device 100 may know that the device may not be complete because the pulling safety device 118 has been previously removed. In some embodiments, the fingers 133 may not spring back into place, but may be permanently deformed when removed from the security hole 147. In such an embodiment, the tail tip 132 may be made weak within the safety hole 147 because the finger protrusions 135 do not abut against the wall of the safety hole. Therefore, in such an embodiment, a potential user may also be reminded of the fact that the pull safety device 118 has been previously removed and the tank may be dissatisfied.

FIG. 18 shows the decontamination device 100 in a dispensing position, where the trigger 106 has been moved from a passive position (eg, FIG. 13) to the dispensing position. As shown, the trigger output 160 may abut the trigger end 164 of the cam member 162, thereby horizontally moving the cam member from the passive position toward the nozzle portion 110 to the dispensing position. When the cam member 162 moves toward the nozzle, the first cam surface 170, the second cam surface 172, and the third cam surface 174 may press the first follower 171, the second follower 173, and the third follower downward, respectively. 175, this can move the mixing manifold from the passive position to the dispensing position toward the first tank 140, the second tank 142, and the third tank 144. The downward movement of the mixing manifold 146 may open the first valve 176, the second valve 178, and the third valve 180, thereby allowing the materials in the corresponding first tank 140, the second tank 142, and the third tank 144 to enter the mixing manifold. , Mix and dispense through the nozzle.

The security hole 247 may be formed relatively wider near its end compared to its entrance so as to receive the first finger 233 and the second finger 234 when the tail tip 232 is in place within the security hole. At least one of the first finger 233 or the second finger 234 may include a finger cam 236. In some embodiments, when the tail tip 232 is pulled out of the safety hole 247, the pressure of the wall of the safety hole on the finger cam 236 may force the second finger 234 toward the first finger 233, thereby Pulling with sufficient force to narrow the gap 235 while overcoming the tendency of the fingers to resist inward movement. In some embodiments, once the tail tip 232 completely disengages from the safety hole 247, the elasticity of the first finger 233 and the second finger 234 can force the distal end to return to the original expanded position. In such an embodiment, the first fingers 233 and the second fingers 234 can be expanded to a width larger than the width of the entrance of the safety hole 247, thereby preventing or limiting the ability to re-insert the tail tip 232 into the safety hole . In such an embodiment, a potential user of the decontamination device 100 may know that the device may not be complete because the pulling safety device 218 has been previously removed. In some embodiments, the first and second fingers 233, 234 may not spring back into place, but may be permanently deformed when removed from the security hole 247. In such an embodiment, the tail tip 232 may be made weak in the safety hole 247 because the finger cam 236 and the first finger 233 and the second finger 234 do not abut against the wall of the safety hole. on. Therefore, in such an embodiment, a potential user may also be reminded of the fact that the pull safety device 218 has been previously removed and the tank may be dissatisfied.
