Bathing shower head device improvement

The present invention is an improvement of a shower head device, in particular, a device capable of preventing leakage, waterproofing, and facilitating assembly of a pressing head.

There are many kinds of bottles for people to hold liquids in their daily life, such as: shower bottles, lotion bottles, body cleaning products bottles, etc., most of them use a pressing head that is separated from the bottle and can be bolted to the user. By pressing the pressing head on the nozzle to extract the liquid in the bottle, however, the structure of the shower head has been continuously developed and innovated by the relevant industry. Although there have been many improvements, the conventional structure is currently visible. In terms of design, there are still problems and shortcomings, such as the following: 1. Please refer to FIG. 7 as a conventional nozzle device 200, as shown in the figure to prevent collision or arbitrary pressing on the indenter 201. At this time, the liquid is leaked out in advance, and the indenter 201 is usually pressed downward and locked to the lower bottle 202. However, just because the indenter 201 is pressed downward, the conventional nozzle is made. The piston 203 of the device 200 is opened to allow the liquid passage 204 to be unblocked. When the bottle 202 is inadvertently in the dumping state, the liquid in the bottle 202 is leaked from the liquid passage 204 or other gap; See 8 is a conventional nozzle device 200. As shown in the figure, the nozzle device 200 is not waterproof, and often causes water to directly infiltrate through the connection gap, thereby deteriorating the liquid in the bottle; 3. Please refer to FIG. The conventional showerhead device 200 is shown in the drawings because the conventional showerhead device 200 is designed separately from the bottle body 202. When assembling the showerhead device 200, the indenter 201 is usually finally assembled on the conventional pressure bar 205. However, conventional pressure is known. The rod 205 itself is not fixed but is swaying, and has the reverse elastic force of the spring 206, so the ram 201 is very difficult to assemble at the time of final tying, or it is extremely easy to damage the ram 201 during improper assembly. .

When the pressing head 1 is pressed downward to rotate the second locking portion 312 and the first locking portion 211 to each other, The tapered portion 63 and the plug portion 421 are fitted to each other to form a sealed state, and the top edge of the inner tube portion 21 is engageable with the convex ring surface 141 and closes the air hole 131 to form an airtight state, when the bottle can 10 When the product is accidentally poured, the liquid in the bottle 10 is sealed and airtight due to the shower head device 100, and the liquid cannot leak from the liquid flow path or other gaps.

Please refer to FIG. 6 , which is a schematic diagram of the shower head device 100 of the present invention. The shower head device 100 proposed by the present invention is pressed by the pressing head 1 during assembly of the pressing head 1 . The first locking portion 211 of the sealing member 2 forms an abutting action with the second locking portion 312 of the pressing rod 3, thereby not only making the pressing rod 3 itself relatively fixed, but also allowing the pressing head 1 to be easily assembled. It is also possible to avoid damage to the pressing head 1 by improper force.

Please refer to Figure 10 for a schematic diagram of the suction stroke of the shower head device of the present invention. The shower head device 100 proposed by the present invention, when the pressing head 1 is loosened, is designed according to the sucking stroke of the creation. When the pressing rod 3 moves upward, the main rod body 42 is temporarily moved, so that the pipe space in the pressing rod 3 is instantaneously increased to generate a pressure difference, and the pressure relationship is allowed to remain in the nozzle 11. The liquid has a suckback action to prevent the residual liquid in the nozzle 11 from being affected by the gravity of the earth.
