## Background
TECHNICAL FIELD OF THE INVENTION
The present invention provides a perfume spray head with leakproof feature, particularly for one that the spray head can be switched into “ON status” or “OFF status” by turning the spraying unit to the position where the flow passage in or out of alignment with the flow path so that effects in component simplification, assembly easiness and cost reduction are achieved.
BACKGROUND OF THE INVENTION
Generally, the principle of the conventional atomized perfume bottle is to well mix the liquid perfume and air in the spray head and to eject it out of the nozzle in atomized effect, wherein the liquid perfume is sucked upwards along the internal liquid feeding channel while the air is come from the air inflator, which is squeezed by the user. By long term investigation, the liquid perfume in the bottle assembled leaks easily in overflow manner in consequence of being upwards risen in the liquid feeding channel due to pressure increasing by the ambient heating temperature during transportation so that it is reckoned as defective product for lack of adequate perfume quantity. In order to solve the issue aforesaid, some industrial businesses get into the study for improving the structure of the conventional perfume bottle and result in certain new models of leakproof perfume bottle continually being introduced such as the Taiwan New Model Patents in numbers of M274839 and M310185. However, after profound research the structure of the introduced new perfume bottle, the inventor of the present invention finds that many trivial tiny components are added to increase the complication of the structure and the difficulty in the fabricating process so that the improvement in the leakproof is at a price, which sacrifices the manufacturing cost and the assembly convenience. Thus, they are not an ideal good products. Having realized and addressed the foregoing issues and drawbacks in the conventional perfume bottle, the inventor of the present invention undertakes a focusing and painstaking research and study through constantly design, test and improvement for a long time.

Regarding the assembly for the “perfume spray head with leakproof feature” of the present invention, please refer to the FIGS. 1 and 3.
Firstly, let the anchoring pin 122 insert into the anchoring hole 121 in the annular pad 12, and rotate the spraying unit 11 up to the position where the curved anchoring trough 117 in alignment with the anchoring pin 122 of the annular pad 12, then load the protrudent docking stem 115 of the spraying unit 11 into the docking pit 123 of the annular pad 12 in proper docking manner so that the anchoring pin 122 of the annular pad 12 securely harbors in the curved anchoring trough 117 of the spraying unit 11 in proper anchoring manner;
Secondly, run the positioning and locking pin 125 through the perforated positioning hole 124 on the annular pad 12 to let its front end being inserted into the corresponding dent of the locking dented ring 116 so that the spraying unit 11 and annular pad 12 are completely docked together into the spray head 1 as shown in the figures;
Thirdly, fix the spray head 1 onto the mounting cap 3 via coupling bushing 128 in unity manner; and
Finally, forcefully drive the plastic liquid feeding tube 4 into the liquid feeding channel 127 of the metal annular pad 12 so that the top outer end of the liquid feeding tube 4 is securely engaged with the internal female thread 127a of the liquid feeding channel 127 to prevent it from dropping off.
By means of the foregoing contrivances, the spray head 1 can be switched into “ON status” or “OFF status” by simply turning the spraying unit 11 of the spray head 1 by the user up to the position where the nozzle 113 in alignment with the mark “ON” 31 on the mounting cap 3 or the position where the nozzle 113 in alignment with the mark “OFF” 32 on the mounting cap 3 in the operation procedure.
To initiate the use of the “perfume spray head with leakproof feature” for the present invention, please refer to FIGS. 4 through 6. When the spraying unit 11 of the spray head 1 is turned by the user up to the position where the nozzle 113 in alignment with the mark “ON” 31 on the mounting cap 3, the flow passage 114 in the spraying unit 11 aligns with the flow path 126 in the annular pad 12 so that both of the flow passage 114 and flow path 126 become communicable in united link manner. Thereby, the open top end of the air intake passage 120 on the annular pad 12 communicates with the air inlet 118 in the spraying unit 11 via the curved anchoring trough 117 in this specific condition to let ambient air out of the spray head 1 be entered into the curved anchoring trough 117 via the air inlet 118 then circulated into the perfume bottle via the spraying unit 11 and the coupling bushing 128 in the annular pad 12 to pump the liquid perfume therein so that the liquid perfume can circulate along the orderly linking fluid path of the liquid feeding tube 4, the flow path 126 of the annular pad 12, the flow passage 114 and the holding groove 111 of the spraying unit 11. Thus, in the holding groove 111 of the spraying unit 11, the liquid perfume is well mixed with the air from the oval-shaped air inflator 2, which is squeezed by the user at this moment, and ejected out the nozzle 113 into atomized perfume via Venturi effect.
Conversely, to finish the use of the “perfume spray head with leakproof feature” for the present invention, please refer to FIGS. 7 through 9. When the spraying unit 11 of the spray head 1 is turned by the user up to the position where the nozzle 113 in alignment with the mark “OFF” 32 on the mounting cap 3, the flow passage 114 in the spraying unit 11 shifts away and out of the alignment with the flow path 126 in the annular pad 12 so that both of the flow passage 114 and flow path 126 become un-communicable in out of link manner with an included angle of 90° to the central axis for each other. At present, both of the flow passage 114 and flow path 126 become blocked owing to the flow passage 114 in the spraying unit 11 being out of alignment with the leakage-proof washer 129c on the annular pad 12 so that the liquid perfume in the perfume bottle can not flow and circulate upwards. Thereby, even the liquid perfume in the bottle is automatically risen upwards along the liquid feeding tube 4 due to certain extrinsic cause, it will be blocked in the flow path 126 of the annular pad 12 without any possibility of getting into the flow passage 114 in the spraying unit 11. Thus, the leakage and overflow of the liquid perfume can be completely avoided. Besides, the air intake passage 120 is also blocked because the open top end of the air intake passage 120 on the annular pad 12 is in a position out of the coverage of the curved anchoring trough 117 so that the no ambient air can enter into the perfume bottle via air inlet 118 to pump the liquid perfume upwards. Thus, in the holding groove 111 of the spraying unit 11, no liquid perfume can be mixed with the air from the oval-shaped air inflator 2 even being squeezed by the user at this moment so that only ambient air is ejected out the nozzle 113 without any atomized perfume.
From the disclosure heretofore, the existing advantages and effects of the present invention are described as below:
1. Simplification of the Components and Structure:
Comparing to the conventional prior arts, the quantity and structure of the components used in the present invention are decreased and simplified so that not only the material preparation and assembly process can be conveniently handled but also the material and handling cost can be significantly reduced. Thus, it has desirable advancement for the industry.
2. Effectively Prevention the Perfume from Leakage:
Because the perfume in the bottle is blocked in the OFF status due to rotational switching contrivance between the spraying unit and the annular pad, the effect of the leakproof is substantially achieved. Moreover, the effect in preventing the perfume overflow and leakage can be enhanced in consequence of the improving sealing function due to multiple leakage-proof washers in the annular pad.
In conclusion, the structural features disclosed in the present invention, which do achieve the expected objects and effects, and have practical value and property of advancement that means the present invention meets the basic patentability criterion of novelty, non-obviousness and practical industrial usage. Accordingly, we submit the patent application in accordance with the related patent laws for your perusal and examination with expectation and appeal for approving us a patent grant, which will be greatly appreciated by us.
