Abstract
A spray head structure capable of preventing backflow of perfume liquid comprises a spray head (1), a locking base (2), a kit (3), a bottle (fig 1, 4) and a compressible ball (fig 1, 5). A rolling ball (133) is held inside a gas-supplying tube (13) of the spray head (1). A cross-shaped trench (141) is formed on one end of a gas-guiding device (14) and several liquid-guiding grooves (142) are formed on the other end of the gas-guiding device (14). The cross-shaped trench (141) supplies the gas with a flow channel and it also prevents the rolling ball (133) from blocking the channel. If the compressed compressible ball (5) is released, the rolling ball (133) will be attracted backward by suction force such that the rolling ball (133) blocks the flow channel and prevents the perfume liquid from flowing into the inside of the compressible ball (5).
Description
SPRAY HEAD STRUCTURE CAPABLE OF PREVENTING
BACKFLOW OF PERFUME LIQUID
The present invention relates to a spray head structure capable of preventing backflow of perfume liquid, and more particularly to a spray head structure that can simply prevents backflow of perfume liquid during operation.
The perfume liquid is taken out by dropping or spraying method, or it may be taken out by use of a compressible ball that attaches to a perfume bottle, wherein the perfume liquid is sprayed out by gas that stores in the compressible ball. When the gas is squeezed out of the spray nozzle by compressing the compressible ball, the perfume liquid is also sprayed out from the perfume bottle to form a uniform mist. However, a backward suction force is generated when the compressed compressible ball is released. As a result, some perfume liquid will be sucked into the compressible ball by the backward suction force. Accordingly, the perfume liquid that remains in the compressible ball may be degenerated, and the degenerated perfume liquid will be sprayed out if the compressible ball is compressed again.
In view of the above-mentioned problems, the present inventor mounts a simple control structure on the gas-supplying tube of the compressible ball to overcome the conventional perfume backflow problem of the compression-type spray head structure.
In accordance with onc aspect of the present invention, a spray head structure capable of preventing backflow of perfume liquid comprises a spray head, a locking base, a kit, a bottle, and a compressible ball. A rolling ball is held inside a gas- supplying tube of the spray head. A cross-shaped trench is formed on one end of a gas-guiding device, and several liquid- guiding grooves are formed on the other end of the gas-guiding device. The cross-shaped trench supplies the gas with a flow channel, and it also prevents the rolling ball from blocking the channel. If the compressed compressible ball is released, the rolling ball will be attracted backward by suction force such that the rolling ball blocks the flow channel and prevents the perfume liquid from flowing into the inside of the compressible ball.
The invention will now be further described, by way of example, with reference to the drawings in which: FIG. 1 is an elevational view showing that the spray head structure of the present invention is coupled with the perfume bottle; FIG. 2 is an elevational view showing the spray head of the present invention; FIG. 3 is an exploded elevational view showing the spray head shown in FIG. 2; FIG. 4 is an exploded elevational view showing the spray head structure of the present invention; FIG. 5 is a schematic plane view showing the inside of the spray head structure of the present invention; FIG. 6 is a schematic view showing that the liquid is sprayed out from the spray head structure of the present invention; and FIG. 7 is a schematic view showing that the spray head structure of the present invention prevents the liquid from backflow.
Referring to FIG. 1, FIG. 2 and FIG. 3, a spray head structure of the present invention that prevents backflow of perfume liquid comprises a spray head 1, a locking base 2, a kit 3, a bottle 4, and a compressible ball 5, wherein the locking base 2 is coupled to the bottle 4. The locking base 2 has a trench 21 formed thereon for holding the kit 3, wherein the locking base 2 is covered with an outer cover 22 and the kit 3 is fixedly inserted into the locking base 2 such that the kit 3 is coupled with the spray head 1. An extension tube 51 that extends from the spray head 1 is coupled with the compressible ball 5 such that the gas stored in the compressible ball 5 can be utilized to spray out the perfume liquid.
FIG. 3, FIG. 4 and FIG. 5 illustrate the detailed structure of the spray head 1. The spray head 1 has a horizontal tunnel 11 and a vertical tunnel 12, which are connected to one another, wherein the horizontal tunnel 11 is designed for holding a gas- supplying tube 13, a gas-guiding device 14, and a spray nozzle 15. The spray nozzle 15 is located on one side of the horizontal tunnel 11. The spray nozzle 15 has a spray hole 152, and several grooves 1 5 1 are formed on an inner surface of the spray nozzle 15 adjacent to the spray hole 152, wherein the grooves 151 are connected to several liquid- guiding grooves 142 of the gas-guiding device 14.
The above-mentioned gas-supplying tube 13 has a through inside, wherein an expansion hole 131 is formed on one side of the gas-supplying tube 13, and a guide surface 132 is formed on an outer edge of the expansion hole 131. A rolling ball 133 is held in the expansion hole 131, and movably located inside the gas-supplying tube 13. The gas-guiding device 14 is inserted into the expansion hole 131, and coupled with the gas- supplying tube 13. A cross-shaped trench 141 is formed on one end of the gas-guiding device 14, and the above-mentioned liquid-guiding grooves 142 are formed on the other end of the gas-guiding device 14. If the gas- guiding device 14 is coupled to the inside of the gas-supplying tube 13, the cross-shaped trench 141 of the gas-guiding device 14 is coupled with the expansion hole 131 and the liquid-guiding grooves 142 are coupled with the spray nozzle 15. Therefore, the gas-guiding device 14 is located between the gas-supplying tube 13 and the spray nozzle 15, and a gap is formed between the gas- supplying tube 1 3 and the spray nozzle 1 5 such that they are not closely coupled with one another. Moreover, a liquid channel 10 is formed between the gas-guiding device 14 and the spray nozzle 15, and the liquid channel 10 is connected to the vertical tunnel 12 of the spray head 1 so as to provide the perfume with a flow channel.
Referring further to FIG. 3 and FIG. 6, the kit 3 is mounted between the spray head 1 and the locking base 2, wherein a liquid straw 32 is attached to the lower end of the kit 3.
Several inner threads 3 11 are formed on the inner surface of the kit 3 corresponding to a liquid container 3 1 that forms on the upper opening of the kit 3. A liquid-guiding device 33 is held in the liquid container 31, and the liquid-guiding device 33 has a sealed lower end on which a through hole 332 is formed. A thread portion 331 is formed on the outer periphery of the liquid-guiding device 33 for engagement with the inner threads 3 11 such that it is able to control the supply of the perfume liquid by screwing operation. In order to prevent the liquid-guiding device 33 from being pushed out, a fixing plate 34 is mounted on the connection portion between the kit 3 and the outer cover 22.
FIG. 1 and FIG. 6 illustrate the spraying operation of the perfume liquid. If there is a need to spray out the perfume liquid, the compressible ball 5 is compressed such that the gas stored inside the compressible ball 5 is guided into the inside of the spray head 1 so as to shift the rolling ball 133 to the cross-shaped trench 141. As a result, the gas is able to flow into the gas-guiding device 14 via the cross-shaped trench 141 such that the perfume liquid that locates originally at the spray nozzle 15 can be carried out by the gas to form uniformly mist.
Furthermore, the perfume liquid flows from the through hole 332 to the liquid-guiding device 33 of the kit 3 via the liquid straw 3, and then flows to the liquid channel 10 continuously.
Accordingly, a proper amount of perfume liquid is sprayed out when the compressible ball 5 is compressed.
Referring further to FIG. 7, if the compressed compressible ball 5 is released, the rolling ball 133 will be sucked backward to the inside of the expansion hole 131 such that the rolling ball 133 can block the perfume liquid to prevent it from flowing into the gas-supplying tube 13 and even into the inside of the compressible ball 5.
The improved spray head structure can prevent the perfume liquid from backflow during the compression operation of the compressible ball 5. In addition, the stability of the mist can be increased by avoiding the backflow of the perfume liquid.
