Light key system
The selectable smooth key system that start unit 48 also comprises a plurality of parts is shown; Said smooth key system be used for confirming reservoir assembly 12 whether with start unit 48 fits, just whether reservoir assembly 12 meets the standard of selecting in advance and uses together to allow with start unit 48.The circuit board 216 of start unit 48 comprises electromagnetic radiation key transmitter 55 and electromagnetic radiation key sensor 56.The lid 212 of start unit 48 comprises the direction sheath 57 and 58 forward of a pair of hollow on the top of its front.Key transmitter 55 is received in the sheath 57 of the cardinal principle column of the lamp of key transmitter 55, and key sensor 56 is received in the sheath 58 of the cardinal principle column of the lamp of key transmitter.Sheath 57 and 58 prevents that basically electromagnetic radiation from passing any transmission of sheath, and effectively with doing that key transmitter 55 and key sensor 56 are carried out orientation, thereby restriction light passes the emission of sheath 57 and 58 outer ends or in the reception any.As Fig. 4 and shown in Figure 7, sleeve pipe 26 has two arms 60 and 61, and said arm extends back with key sensor 57 towards each key transmitter 55 respectively from sleeve pipe 26.Sleeve pipe 26 provides from the electromagnetic radiation guide of the end face of the end of arm 60 62 through the face 63 of the end of sleeve pipe 26 to arm 61, and 63 pairs of waveguides of the face of the end of arm 61 provide outlet.Said waveguide is being to extend with substantially U-shaped in the U-shaped edge 65 at material shown in Fig. 7 schematically with dotted line 64, and said material is provided with near the upper end 35 of sleeve pipe 26 around sleeve pipe 26 peripheries.
With reference to figure 4; Electromagnetic radiation through 55 emissions of key transmitter gets into waveguide 64 via entrance face 62; And pass sleeve pipe 26 conduction via said waveguide 64, electromagnetic radiation is drawn waveguide 64 via exit end face 63, and radiation is drawn waveguide with through key sensor 56 sensings via exit end face 63.Start unit 48 comprises key control system, under this precondition as dispensing, considers the electromagnetic radiation through 55 emissions of key transmitter, will be consistent with the parameter of one or more preliminary elections through the electromagnetic radiation of key sensor 56 sensings.Through non-limiting instance, key transmitter 55 can be launched electromagnetic radiation in the wave-length coverage of selecting, and during electromagnetic radiation in lacking key sensor 56 sensing emitted radiation scopes, will not allow motor 49 work.Thus; When the simplest situation; If have bottle 22, pump assembly 25, and the non-habitual reservoir assembly 12 that does not have a sleeve pipe 26 is linked to back board component 14, but also does not have waveguide; The radiation of the selection wavelength through key transmitter 55 emission will can not be carried out orientation or through key sensor 56 sensings, and the controlling organization of start unit will not allowed to be betrothed to send.
In preferred embodiment, sleeve pipe 26 can be preferably through being formed by the plastic material injection molding, and said plastic material allows electromagnetic radiation to pass this plastic material transmission.Those skilled in the art will appreciate that the multiple plastic material that can use such as polycarbonate plastic.Said plastic material will provide the direct product with electromagnetic radiation transport property.Because light reflects on the outer surface of the sleeve pipe that effectively forms the waveguide side with less relatively angle, can get into light transmission sleeve pipe 26 and be oriented orthogonal to the radiation of entrance face 62 will be to a certain extent in internal reflection.The directed partial radiation that gets in the sleeve pipe 26 will pass sleeve pipe 26 around U-shaped external margin 65, and a part of radiation will be orientated and be approximately perpendicular to exit end face 63 to draw waveguide and through key sensor 56 sensings.
According to the present invention, the electromagnetic radiation that is used for the key transmitter can consider that preselected parameter selects.These parameters can comprise the radiation in one or more wave-length coverages, the electromagnetic radiation in one or more strength ranges, the electromagnetic radiation of polarization and in one or more duration scopes and in the electromagnetic radiation of one or more different time points.
The waveguide that is provided can have following electromagnetic radiation transmission characteristic, said electromagnetic radiation transmission characteristic be selected from multifrequency nature and comprise the ability of transmitting one or more wave-length coverages and/or the ability of blocking one or more wave-length coverages, preferably as the ability of the intensity of the electromagnetic radiation of the restricted passage waveguide of a kind of function of most of waveguides.Transmission characteristic can limit the transmission of the radiation with first wave-length coverage, and allows the transmission of the radiation with second wave-length coverage.
For the essence of electromagnetic radiation to be used, many available traditionally sensors and/or transmitter can be used for launching and the electromagnetic radiation of sensing visible spectrum.Yet this is not necessary, can use the outer electromagnetic radiation of visible spectrum yet.This helps hiding the essence that can comprise the modular unit of partial waveguide arbitrarily.For example, whether the operational blocks which partition system waveguide component seems has such as blue, red or yellow color visible light, when the operational blocks which partition system waveguide component is suitable for carrying out the transmission of invisible electromagnetic radiation, then in the modular unit existence of color or lack with help the deception person of imitateing.
According to preferred embodiment, circuit board 216 just is set to through the electronics that minimizing is carried simply, thereby is easy to electrical ties motor 49.Feel examining system parts comprise sensor 53 and transmitter 54, and selectable key system comprises key transmitter 55 and key sensor 57.According to the present invention, the key system must be provided, and should be understood that thus when this situation, the dispenser that does not have key transmitter 55 or key sensor 56 or its sheath and do not have sleeve pipe 26 can be provided.Disclosed embodiment can be through cancelling these elements and only comprising through insertion and to realize function at the reservoir assembly shown in Fig. 6.
Though the present invention's reference preferred embodiment is described, yet those skilled in the art will expect multiple modification and remodeling.Should be for of the present invention defining with reference to following claims.
