The specific embodiment

Fig. 1 shows the transparent view according to the door 5 that spray dispenser 10 is housed of first embodiment of the invention.Spray dispenser 10 can be operated with from spray disinfection agent 2 wherein and cover outward extending grip handle 14, thereby it is carried out disinfection.Fig. 2 shows the exploded drawings of distributing box 10.

Referring to Fig. 1 and Fig. 2, spray dispenser 10 comprises the control button 23 that shell 21, pedestal 22, user can contact and is used to provide the control of distributing box 10 and the appreciiable indicator lamp 24 of status information.

Spray dispenser 10 preferably is installed on the top of the grip handle 14 of door 5, as shown in FIG..Shell 21 is hinged by boss 38 and pedestal 22.Boss 38 is configured to run through the hole 39 of housing 21, and allows shell 21 to rotate between off position and open position.At off position, shell 21 hides the inner member of distributing box 10 fully, and at open position, and shell 21 provides towards sterilant source 47 and distributing box 10 and the inlet that is contained in other inner member (as power supply 45) in the distributing box 10.

The shell 21 of spray dispenser 10 comprises roof 27 and diapire 28, in order to show pleasant outward appearance, also comprises crooked antetheca 26.Distributing box 10 also comprises component support wall 29, and most of inner members of spray dispenser 10 attach on the supporting walls 29.

Sterilant source 47 (preferably adopting the form of spray container) is removably mounted in the spray dispenser 10.Particularly, referring to Fig. 3, sterilant source 47 is kept by erecting frame 49.The function of erecting frame 49 is that sterilant source 47 is fixed on the appropriate location, and its nozzle (valve 57) is aimed at the long nozzle 56 of spray activator 52.Under the situation that sterilant source 47 must be changed, erecting frame 49 also provides the mode of effectively taking off sterilant source 47.As shown in the figure, erecting frame 49 be preferably have bottom 81 and from the bottom U-shaped of 81 extended two arms 83, two arms 83 are used for sterilant source 47 is fixed between the two.Bottom 81 is fixed on the component support wall 29.Erecting frame 49 should have flexibility, but so that arm 83 cross bending are inserted in the space common between two arms (confounds) to allow sterilant source 47, keeps their shape simultaneously, thereby support the weight of sterilant source 47 fully.Therefore, only need, sterilant source 47 " can be snapped in " support 49 or, neither can destroy support, also can not destroy sterilant source from wherein " taking-up " with very little power.And as mentioned above, this is enough to sterilant source 47 is fixed in the appropriate location in the spray dispenser 10 and need not extra anchor fitting.One of skill in the art will recognize that, also available various optional erecting equipment is fixed in sterilant source in the spray dispenser 10, for example Velcro band, rope, belt, clip etc., and can easily be suitable for playing a role with this optional anchor fitting according to spray dispenser 10 of the present invention.

Motor 50, gear 54, arm 55, long nozzle 56 and spring 57 are collectively referred to as spray activator 52 at this, and it is supported in the motor erecting frame 51.The same with above-mentioned erecting frame 49, motor erecting frame 51 also is attached on the component support wall 29 securely.When shell 21 was positioned at detent position, erecting

frame

51 and 49, sterilant source 47 and spray activator 52 were blocked under the covering of shell 21 and are invisible.Below with reference to Fig. 3-5, the relation between the discrete-component of detailed description spray activator 52 and their operations when mechanically influencing from sterilant source 47 discharge bactericidal agent 2.

Arm 55 is articulated on the electric machine support 51, and supports long nozzle 56.The valve 57 of sterilant source 47 is aimed at long nozzle 56, and the connection of flowing with it.Referring to Fig. 3-5, motor 50 is DC machine preferably, and can operate with driven wheel 54 cws and turn over an angle.Clockwise rotating of gear 54 makes arm 55 rotate counterclockwise.Arm 55 is synchronized with the movement with nozzle 56, and nozzle 56 preferably includes configuration and is used for accepting the upwards bearing surface or the friction face of propulsive effort from arm 55.Because long nozzle 56 is connected with arm 55, the promotion nozzle 56 that rotates counterclockwise of arm 55 upwards leans valve 57, applies to it and opens valve 57 temporarily and discharge the required power that makes progress (Fig. 5) of the bactericidal agent that held in the sterilant source 47 2.The bactericidal agent 2 of discharging from valve 57 flows into long nozzle 56, and long nozzle 56 outwards guides to bactericidal agent 2 ambient air from spray dispenser 10 and reaches on the grip handle 14.Spring 58 is attached between arm 55 and the motor mounting rack 51 regularly, and for make arm 55 contact with gear 54 and promoted by gear 54 after can return to normal position (as shown in Figure 4), spring 58 is necessary.

Should be appreciated that motor mounting rack 51 supports the element of the spray activator 52 in the spray dispenser 10, and can not collide with shifting out of sterilant source 47.As shown in Figure 4, spray activator 52 is preferably located in the bottom of sterilant source 47, and is disposed like this: when sterilant source 47 was positioned at the appropriate location of spray dispenser 10, long nozzle 56 was positioned on the straight line with valve 57, and partly around valve 57.

Referring to Fig. 5, preferably gear 54 disposes equally spaced projection or recess, outstanding or recess and can contact also that pusher arm 55 rotates as mentioned above like that with arm 55 on pivot along its periphery.Because the promotion of 54 pairs of arms 55 of gear makes valve 57 open, arm 55 is promoted far more by gear, and it is just long more that valve 57 stays open time of state, and the amount of the bactericidal agent 2 of discharge is just many more.The angle of gear 54 rotations all can influence the length that valve 57 is opened the time when interval between the projection on the gear 54, the width of each projection and motor 50 each startups, thereby also has influence on the amount of the bactericidal agent 2 that each given startup discharges.Therefore, can control the amount of the bactericidal agent that spray dispenser discharged between 10 each starting periods, and by gear 54 is configured, the time that contact pusher arm 55 also when making its each rotation with arm 55 is longer or shorter, and the increase or the minimizing of the amount of realization bactericidal agent 2.

In optional structure, spray activator 52 is configurable different gears, so that realize opening of spray valve 57 temporarily.Referring to Fig. 6, the projection of gear 54 equal intervals shown in Figure 5 is replaced by a series of convex tendon, and convex tendon is corresponding with a series of accommodation hole on the arm 450.Can gear 449 be configured by regulating the quantity and the size of convex tendon, to allow at different time gaps to valve 57 application of forces.Thereby the amount of the bactericidal agent on the handle is discharged and finally is injected in influence from valve.In other structure, spray activator 52 also can be configured to potion or ampoule bactericidal agent pressurization from liquid storage pool, so that the fluid of pressurization is discharged on the handle 14 as spraying.

Referring to Fig. 4 and Fig. 5, the through hole 68 on the diapire 28 of long nozzle 56 and housing 21 is aimed at.Through hole 68 is as the entrance, and long nozzle 56 stretches out shell 21 by through hole 68.Long nozzle 56 is connected with sterilant source 47 fluids by valve 57, with the bactericidal agent of reception from sterilant source 47, and long nozzle 56 is oriented to axis size A (Fig. 1) with housing 21, from the diapire 28 of housing 21 handle 14 injection bactericidal agent towards door 5.The injection 72 of this outside guiding should have strength and width, with the whole periphery 15 that covers handle 14 fully at least half.

Referring to Fig. 2, when spray dispenser 10 is installed, near (for example, above the grip handle on the door) positioning pedestal 22 grip handle 14 at first, and by screw 35 pedestal 22 is fixed on the door.Then, adopt any conventional fixed or lock mode (as screw, adhesive agent, Velcro, clip, flexible clamping structure etc.) that component support wall 29 is installed on the pedestal 22.At last, battery 45 is packed in the battery cavities 44, sterilant source 47 is inserted in the erecting frames 49, and shell 21 is attached to regularly on the support rim 38 of pedestal 21.Can close now shell 21 with hide fully supporting walls 29 and on element, and can start spray dispenser 10.

As Fig. 7 and Fig. 8 shown in further like that, boss 38 is configured to be supported in the hole 39 of shell 21, and provides pivot joint campaign around boss 38 to shell, thus permission by rotational shell 21 make its away from pedestal 22 " opening " spray dispenser 10; And by shell 21 is rotated and " closing " spray dispenser 10 towards pedestal 22.Therefore, can realize fully near battery cavities 44 and bactericidal agent 47.Alternatively, shell can link to each other by the buckle release of lock or band key with pedestal, touches to prevent unauthorized persons.

Be loaded on sterilant source 47 bactericidal agent 2 interior and that be injected on the handle 14 and can comprise liquid germicide, spray, mist of oil etc., preferably, the feature of bactericidal agent is that its mating surfaces just can be killed virus to the surface.According to optional embodiment of the present invention, bactericidal agent 2 comprises the chemical solution based on chlorine because (comparing) with solution based on alcohol it relative nonflammable fluid is provided, and also provide above-mentioned virus killing function.Should be appreciated that the term " bactericidal agent " that uses is not limited to the chemical solution or the fluid of any Special Category herein, the scope of this term and implication comprise any suitable fluid or the composite as disinfectant.Randomly, can comprise odor additive in the fluid, so that the virus killing fluid also plays the effect of air freshener.

Under some environment, it is first-class for example to be installed in door, and spray dispenser 10 in time distributes bactericidal agent 2 with certain given time gap (for example clock switch, clock control etc.).According to optional aspect of the present invention, spray activator 52 can be triggered in response to the operation (for example after everyone operation or after the given a series of this operation) of grip handle 14.Under latter event, after reaching preset count, counting machine can start the discharge of bactericidal agent 2.These situations of being quoted all are the examples of Control Software program.These software programs are responsible for when detecting predetermined state or function just, by starting the handle disinfecting process, finish aforesaid sterilization method automatically.

Referring to Fig. 9, there is shown selectable further structure, wherein antetheca 26 further comprises the sensor 95 that is used to trigger spray activator 52.Sensor 95 can be the combination of optics, infrared, mechanical/electrical or the sensor.Therefore, in this structure, when people or action being arranged near detecting handle or detecting light interruption or vibration, regulating control 52 can start injection.Alternatively, sensor 95 can be used for making injection equipment to lose efficacy, or closes this parts in the special time period, rather than starts injection equipment.For example, as mentioned above, may command spray dispenser 10 distributes bactericidal agent 2 with given time gap, and sensor 95 can be used for when it detects certain state, and spray dispenser was lost efficacy.For example, sensor 95 can comprise optical pickocff, and is switched off or the people is triggered during near these parts when lamp, to stop further injection.

Referring to Figure 10, Figure 10 shows the front elevation of the door handle sanitizer 100 with further optional structure.Handle sterilizing equipment decontaminating apparatus as shown in Figure 3 is such, and handle sterilizing equipment decontaminating apparatus 100 comprises the motor 50 and first train of gears, and first train of gears comprises gear 54 and 55.Referring to Figure 10, further structure comprises second train of gears, and second train of gears comprises spray gears 102,103 and 109, mechanical shutter 105, gate motion sensor 106, nozzle 104, easily broken connector 107, axle 114 and gear-bearing hollow tubular 108.As shown in the figure, second train of gears and first train of gears are isolated, but by connecting device and the coupling of first train of gears.In addition, gate 105 and motion sensor 106 are used to stop spray (aerosol) injection, unless gear 102,103,109 is set to motion by the track 111 that is positioned on the gear-bearing hollow tubular 108.Gear wheel shaft is in the charge of 108 spray is delivered to nozzle 104 from the valve 57 of spray container 47, and enters cone shaped opening 110, then from spraying equipment 10 outputs.

When gate 105 was static, it stoped aerosol spray to spray from nozzle 104.Pipe 108 and shooting valve 57 be vertical shifting (as shown in the figure) reciprocally, means that when pipe 108 moves under the promotion of arm 55 (as described in reference Fig. 5), pipe 108 and valve 57 are pushed to spray container 47, makes that moment sprays spray from container.Valve 57, nozzle 104 and manage 108 fluids and be connected, thereby the aerosol spray of discharging from valve 57 enters nozzle 104 by managing 108 are then from the shell ejection of door handle sanitizer 100.

The motion of gear 102,103 and 109 fit tube 108, and have selected movement rate makes gate 105 rapid movement, thereby is aerosol spray cleaning path in response to the less relatively crank motion of pipe 108.Be positioned at external component (track 11) and pipe 108 same moved further on the pipe 108.Track 111 can comprise a series of bearing surfaces (as tooth, groove or slit), and this bearing surface operationally cooperates with the parts that hold on the gear 102.When arm 55 promotion pipes 108 moved up, track 111 made gear 102 left-hand revolutions.Gear 103 is by gear 109 mechanically engagement between gear 102 and gate 105.Gear 103 rotates counterclockwise in response to the motion of gear 102, and promotes gate 105 motions.Preferably, gear 109 is at least than

gear

102 and 103 little two orders of magnitude, and is installed on securely on the gear 103, so that the advantage of machinery to be provided, thereby to manage 108 and makes the bigger translation of gate 105 relative tapered openings 110 dos in a spot of translation of vertical direction meeting.This is absolutely necessary for gate 105 overcomes most of at least (the good portion) of distance of tapered opening 110, and this distance is bigger in the miles of relative movement of vertical direction than managing 108.The effect that the conter clockwise motion of gear 103 is produced is that gate 105 is pushed to deviation post, thereby makes it open tapered opening 110, allows aerosol spray from wherein spraying.This point is to realize by comprise the bearing surface or the friction face that cooperate with gear 103 on the part of gate 105 sides, thereby the passive rotation of gear 103 moves gate 105.This hole persons of ordinary skill in the art will recognize that the hole that any general pattern can be set on the gate 105, as long as can be mated with the corresponding hole on the gear 103.

Gate 105 comprises from outward extending flexible portion of its mid point or element, therefore as mentioned above, can operate when gate 105 moves under the driving of gear 103 with around axle 114 bendings.Because pipe 108 indents, the tapered opening 110 on the housing 100 is preferred, therefore when aerosol spray when housing is discharged, it has the pattern of uniform distribution.

Start after the pipe 108, aerosol spray is discharged from spray dispenser 100, pipe 108 will be got back to quiescence, and make the reversing of motion of gear 102,103 and 109, thereby make gate 105 get back to its dead position (for example, closing tapered opening 110).Except all gears all in the opposite direction the motion, pipe 108 move downward with previously described identical.

Sensor 106 (being embodied as switch in Figure 10) is oriented to survey the motion of gate 105 and the exposure of nozzle 104.When gear 103 setting in motions, it moves gate 105, thereby contacts with sensor 106.Sensor 106 is connected with control circuit 31 (Fig. 2), and in response to the triggering that gate 105 moves, sends motor message to control circuit.This motor message represents that gate 105 has moved the scheduled volume that is suitable for sensor 106 detections.Sensor can comprise mechanical switch, but persons of ordinary skill in the art will recognize that and can adopt the sensor of other type to replace mechanical switch, for example electromechanical pickup, optical pickocff or magnetic pickup device.No matter adopt the sensor 106 of which kind of type, it must be so positioned or dispose: can operate with the motion of search gate Men Zaiyi direction at least (as opening of gate at every turn).

Door handle sanitizer 100 also comprise be programmed in the control circuit 31 or spray dispenser in other local software, to monitor the motion of any detected gate 105.A kind of mode of detected gate 105 motions of software monitors is the state variation in the testing sensor 106.In this manner, sensor 106 can be configured to become closed condition and get back to open mode from closed condition from open mode in an injection cycle.If in certain specific time cycle, state variation does not take place sensor 106, the mechanism of then deducibility door handle sanitizer 100 had lost efficacy or had been changed, and had perhaps adopted unauthorized spray container.In this case, software can suspend further spray cycles.Software preferably includes timing circuit, to determine to continue to allow to trigger the motion of the required gate 105 of aerosol spray.According to remarkable aspect of the present invention, timing circuit can be replaced by optical distance sensor (optical proximity sensor) (not shown), as the description of front about the sensor 95 of Fig. 9, this sensor can be used in some cases (for example non-time to peak of work) lost efficacy sterilizing equipment decontaminating apparatus 100.

The reset routine that software can built-inly make control circuit 31 reset, thus after suspending, spray cycles activates this control circuit again.Reset routine can mechanically be activated, and in this case, but grantee's manual triggers is positioned at the reset switch (not shown) on the shell.As a kind of selection, reset routine can be organized in the software automatically, thereby control circuit 31 is resetted, so that continuing to recover spray cycles after the predetermined stop time owing to lacking the motor message that offers software.

According to another aspect of the present invention and please continuing, will manage 108 valves 57 that are connected to spray container 47 by seccotine, epoxy resin or melting welding (being that fusion connects), and connection pipe 108 can prevent to manage 108 and separates with valve 57 referring to Figure 10.The connector 107 that easily unloads is located between first end and track 111 of pipe 108, and is used to weaken the connection between the two.The connector 107 that easily unloads is preferably formed by the material of pipe 108, but can be included in the independent component that is configured with fragile part in the connector 107, if thereby someone attempt makes pipe 108 separate with valve 57, then make pipe 108 fractures in position near the shooting valve 57 of spray container.Preferably, easily broken connector 107 comprises indentation (score), perforation, line of rupture or than valve 57 with manage other more fragile parts of connection between 108.Easily broken connector 107 is as attempting that as the people spray container 47 is separated with pipe 108 and safety component when it is reused with another container.Its structure can be operated so that manage 108 fractures, shortens its entire length, and if described afterwards pipe and another valve 57 reconnect, make that then it can not driven wheel 102, because track 111 will no longer be aimed at gear 102.

But Figure 11 and 12 is respectively front elevation and lateral plan according to the door handle sanitizer 200 of the arrangement of door handle sanitizer shown in Figure 10.Except axle 114, the optional configuration shown in Figure 11 and 12 comprises all elements of describing with reference to Figure 10, but and should arrangement have compacter form, the gear that needs lacks one than the scheme of Figure 10.Door handle sanitizer 200 comprises that

gear

202 and 203, mechanical shutter 105, gate sensor 106, nozzle 104, easily broken connector 107 and gear wheel shaft be in the charge of 108.It is identical that the function of gate 105 and motion sensor 106 keeps: promptly hinder aerosol spray, make

gear

202 and 203 setting in motions unless be positioned at the track 111 that gear wheel shaft is in the charge of on 108.Gear wheel shaft be in the charge of 108 with spray from the valve 57 of spray container 47 by tapered opening 110 by nozzle 104 from spraying equipment 200 outputs.
