The specific embodiment
Described device comprises functional unit shown in Figure 22, and this functional unit is covered by cover cap shown in Figure 14.Described cover cap has bandy antetheca and rear wall, and each wall all has a series of curved slot 6, their appearance looks elegant, but also play inlet channel.This cover cap also has less vent 8 at the highest point of its front surface area.Can see that this cover cap is tapered towards vent 8, thereby have the form of the ventilator (funnel) 9 that leads to vent 8.Described cover cap all has central elliptic region 10 on each curved wall.On side shown in Figure 1, this zone is opened wide, thereby user can be seen inner functional unit, and with the state of eyes judgment means.Yet although open wide, because operating member is blocked to a great extent, so it does not play air inlet.Corresponding central elliptic region on opposite side is the form of plate.
In Fig. 1, the shape of the opening of air duct (elevation) is with shadow representation, and the surrounding structure of described cover cap is represented with white.As can be seen, on side shown in the cover cap, have four inlet channels.They are provided with in pairs, roughly around central elliptic region 10 bendings, and close this elliptic region of less inlet channel, and bigger passage is away from this zone.Each inlet channel all can be described as crescent or banana-shaped.The inlet channel that four correspondences are arranged in a unshowned side.
Each inlet channel all has front curvature edge 6a, 6a ', 6b, 6b ' or the like (see Fig. 6, see Fig. 1, Fig. 7 simultaneously)." front portion " is meant the entrance side of corresponding inlet channel, that is to say, at the outer side of cover cap.Dangle from each the front curvature edge solid wall portion of cover cap.It can be the part (for example for edge 6a part 6c) of cover cap wall main body, perhaps can be that the flared part (flared part) that dangles from this edge is (for example for the part 6d of edge 6a '; Part 6e for edge 6b; Part 6f for edge 6b ').
Each inlet channel is designed so that an edge and described solid wall portion are overlapping.In other words, the air through inlet channel must flow between this edge (and the solid wall portion of dangling from this edge) and described solid wall portion; Thereby this edge and solid wall portion form a pair of louver, and the part that limits between them can be known as passage.The feature of this " overlapping " has obtained best illustration by the inlet channel that is expressed as 6g and 6h in Fig. 7.
Total cross-sectional area of eight inlet channels approximately is 24cm
2
Because above-mentioned architectural feature, as shown in Figure 7, air enters this device along zigzag path, illustrates by the left-hand side passage to meaning as shown by arrows.Although in the side view of Fig. 1, can see the inside (shadow region) of cover cap, do not think that air can be along the straight line inflow device and not deflection in the above described manner by passage.
When (see figure 5) when the front is seen, because above-mentioned overlapping, therefore can not see the inside of cover cap.Appreciable from this view is not inlet channel, but flared overhang 6d ', 6f ' (seeing Fig. 1 equally).
Described cover cap is molded into have sag and swell two housings of (11a, 11b-Fig. 6,7), and this sag and swell makes these two housings to be force-fitted in together.In Fig. 4 and Fig. 5, can be clear that closing line.
Described cover cap finishes with socket structure 12 in its bottom, and cover cap can be assembled on the functional unit by this socket structure.
Functional unit shown in Fig. 2 comprises base unit 14 and is assembled to the interior tube box 16 of this base unit.
Described base unit comprises the pedestal 17 of below, and this pedestal has axial sidewall, and the socket structure 12 of decorating cover cap 4 cooperates (interface fit) to be fitted thereon with the interfaces of appropriateness.
Motor 18 is installed on this base unit.Fan 20 is installed again on the motor 18.As can be known, fan 20 is provided with to such an extent that be higher than motor 18 by axle 19.
Include simple electronics (PCB) the timing circuit (not shown) that is used to control described motor in the base unit 17.User can utilize switch 21 to control motor by circuit, and this switch 21 is positioned at the front portion of base unit, and can be approaching by cover cap.This switch has pass, conventional and strengthen the position, and this makes can low (or passive), the neutralization height is described steam output.
Base unit 17 is formed with socket, and tube box 16 is assembled in it in the mode of snap fit.
This box has: battery chamber 22 (being represented by dotted lines in Fig. 3); Bin 24 is used for transpirable chemicals; Relative thinner column core 26 (in Fig. 2, representing) with close hacures, extend its bottom from bin, and pass the hole in the roof of this bin; And the plate-like device 28 of emanating, it is supported on the far-end of core 26.The core and the device of emanating be not for having the capillary material of any non-capillary tube through hole.
The battery chamber is designed to hold two joint AA batteries.It is closed by the independent diapire 30 that forms.This battery chamber is factory's sealing unit.Diapire 30 has the required opening that electrically contacts of the realization of allowing.Remove diapire and can destroy the battery chamber, and make it non-exchange.
Bin has diapire 32, and the sidewall of this diapire and tube box is co-molded in once-through operation.Can find out that in Fig. 3 the cross section of one of sidewall 34 of bin is a S shape, but tube box upper end (36 places at the edge) is circular.Bin has the inclined wall 38 of depression between S shape sidewall 34 and top edge 36.This also can be as seen from Figure 2.Therefore, bin has the wall portion that overhangs of protruding towards flow path, and this wall portion and overhangs approximately its half above fan.
The roof of bin is not shown, but in fact it have the quatrefoil opening that core passes through.Four curved edges clamping cores of this opening, and leave four spaces, be used for ventilating or aerofluxus.Therefore, described opening helps core is remained on the appropriate location, and in addition, core is against the inwall (as shown in Figure 2) of battery chamber.In addition, a less cup-shaped conformation (not shown) is arranged, be used to make the core end to stand upright on wherein at the diapire of bin.
In the present embodiment, the device 28 of emanating is that diameter is that 33cm, thickness are the disk of 5mm.By comparison, the diameter of core is 5.2mm.The gap 39 that 5mm is arranged between the roof of device 28 and bin of emanating.The diameter of device of emanating is roughly the same with the internal diameter at edge 36 of tube box.
For using this device, by socket 12 being placed on the pedestal 17 and cover cap is positioned at the appropriate location.If user is selected conventional or is strengthened the position, then the open/close state of timing circuit control motor.For example, for routine operation, motor may have the repeat mode of " opened in a minute, closed in five minutes ", and is strengthening the position, and motor may have the repeat mode of " opened in a minute, closed in two minutes ".When motor was operated, fan upwards promoted air.Overhang wall portion 38 near fan, and the turbulent flow that is used to make the interior air deflection of device and/or increases air flow.Although may think that this can hinder the air flow that flows to the device of emanating, yet owing to can't understand, this has improved the operation of device.By 8 the zigzag path from fan 20 to vent, air is estimated to flow through emanating device in the mode of strong turbulent flow.As can be known, air flows in the above and below of the apparatus surface of emanating.Find that allowing air to flow through from the device below of emanating is of value to the acquisition controllable device, reason is unclear as yet.The air of Zheng Fa chemicals arrives vent 8 through ventilator 9 abrim, enters the outside atmosphere space through vent 8 then.
Described device is designed to like this, so that the time that chemicals uses up should be consistent with the time that battery uses up.If described concordance and inaccuracy, then chemicals can use up earlier, and battery life-span a little also.User can be bought the replacement tube box that has identical or different volatility chemicals and contained new battery.This replacement tube box includes new core and the device of emanating.For preventing the loss during transportation and shop display, replace the tube box and seal by a thread cap cover (not shown).Screw thread on the tube box has been shown in Fig. 2 and Fig. 3, has been designated as 40.User needs only dismounting and abandons this cap, vertically holds a box, then this box is imported in the socket of pedestal, and cover is replaced, and the device after installing just can have been used.Cap is of a size of such size, make when it in position the time, cover cap can not be positioned at the top of functional unit.
Fig. 8 shows the performance that the foregoing description adopts two kinds of different spice (Citrus flavor spice and vanilla flavored spice) with Fig. 9.Compare with above-mentioned related device, this embodiment is used in its passive pattern of distributing, and this belongs to the present invention equally, but has unlimited " window " rather than inlet channel on cover cap." window " is positioned at the position similar with the inlet channel of first embodiment.The spatial domain gross area that opens wide of two cover caps all is 24cm
2The both has 15cm
3Specific spice.Also tested a kind of commercial plug-in system of the present invention that do not belong to, it has the heater that is used to promote to be suitable for the evaporation that its minimum thermal sets, and has 21cm
2Spice, but do not have fan or a cover cap.
The effect as a result that device by Fig. 1-7 obtains is remarkable.Can find out that even stage in the early stage, emission rate is also well below other devices.Result for the device that has unlimited " window " cover cap is better than commercial plug-in type product, but is not so good as the result by the device acquisition of Fig. 1-7.
In another embodiment, very close to each other between the roof of device and bin of emanating.The device of emanating can lean against on roof or the flange, and this roof or flange have formed the base that is used for this device of emanating.This set causes slower distributing than the setting shown in Fig. 1-7, and prevents from more reliably to overflow.
One recess walls is arranged in another embodiment, and it is transverse to the axis of fan, is preferably vertically rather than wall as shown in Figure 2 38 tilts like that.Can expect that the lateral recesses wall will produce bigger turbulent flow, thereby be of value to operation.
In another embodiment, not shown battery case among Fig. 3.On the contrary, it can have molded feature, this means to have only positive terminal can be contained in the end regions of a battery location, and has only negative terminal can be contained in the respective end zone of another battery location.In addition, these two battery locations can separate with partition wall.This is intended to forbid carrying out incorrect battery and inserts.
