Description

IMPROVED SEALING STRUCTURE FOR THE ROTARY VALVE
OF SQUIRTING GUN
The present invention relates generally to a squirting gun, and more particularly to an innovative one which is designed with improved sealing structure for the rotary valve.
Given the fact that traditional squirting guns cannot meet the diversified customer demands due to uncontrollable water discharge, the inventor has developed a controlled structure of squirting gun as shown in Figure 1. The feature of squirting gun 10 is that, a rotary valve 14 is placed between inlet duct 12 and outlet duct 13 of the bodyll. The rotary valve 14 could be coupled to a button 15 outside of the bodyll such that it is possible to control its rotating angle and also the switching or misaligning state between through-hole 16 of rotary valve 14 and inlet/outlet duct 12, 13. And, a water sealer 20 is configured at the connecting end of outlet duct 13 and rotary valve 14. The water sealer 20 comprises a flexible seal ring 21 used to fix its locating ring 22. The configuration of water sealer 20 is to prevent any water leakage when rotary valve 14 is closed alternatively. The major purpose of the present invention is to improve the water sealer 20 so as to reduce the consumption of raw materials, and also save manufacturing and assembly cost.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement if the art to provide an improved structure that can significantly improve the efficacy. *1
To this end, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
The enhanced efficacy of the present invention is as follows: The "improved sealing structure for the rotary valve of squirting gun" of the present invention is based upon an innovative design that a flexible sealer is placed onto outer wall of the rotary valve 30 oppositely to outlet duct 42 of squirting gun body 40. When the through-hole 30 of rotary valve 30 misaligns with inlet/outlet duct 41, 42, the flexible sealer could be placed oppositely to outlet duct 42 to avoid water leakage. As compared to conventional water sealer of (prior art) which comprises flexible seal ring and locating ring, the present invention allows the user to install a trough 33 onto outer wall of the rotary valve and also a sealer 60, or employs a flexible surface 70 to serve the purpose of water leakage. Thus, it is possible to reduce the components and save the manufacturing and assembly cost for better industrial applications.
According to the present invention there is provided an apparatus and method as set forth in the appended claims. Preferred features of the invention will be apparent from the dependent claims, and the description which follows.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
Figure 1 shows an assembled sectional view of the present invention; Figure 2 shows an exploded perspective view of the present invention; Figure 3 shows a partially enlarged perspective view of the present invention; Figure 4 shows an assembled sectional view of the present invention, when water supply is turned on; Figure 5 shows a partially enlarged view of rotary valve in Figure 4; Figure 6 shows another assembled sectional view of the present invention, when water supply is turned of f; Figure 7 shows a partially enlarged view of rotary valve in Figure 6; Figure 8 shows another preferred embodiment of trough and sealer of the present invention; Figure 9 shows another preferred embodiment of flexible sealer of the present invention; Figure 10 shows an abridged general view of the structure in Figure 9; Figure 11 shows a perspective view of another preferred embodiment of flexible sealer of the present invention; and Figure 12 shows a sectional view of another preferred embodiment of flexible sealer of the present invention.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
Figures 1, 2, 3, 4, 5 depict preferred embodiments of improved sealing structure for the rotary valve of squirting gun of the present invention, which, however, are provided for only explanatory purpose for patent claims. The said rotary valve 30 is placed into a housing 43 of squirting gun body 40, which is axially installed between inlet duct 41 and outlet duct 42. The rotary valve is provided with a radial through-hole 31. At both sides of rotary valve 30, watertight rings 32 are assembled to be mated closely with the housing 43. And, the both ends of the rotary valve 30 are connected to a convex button 50 outside of squirting gun body 40, such that the rotation angle of rotary valve 30 could be adjusted by the button 50 to control the switching or misaligning state between through-hole 31 of rotary valve and inlet/outlet duct 41, 42. The key design of the present invention is: a flexible sealer is placed into outer wall of rotary valve 30 oppositely to outlet duct 32 of squirting gun body 40. The said flexible sealer is available with several embodiments as described below: Figures 2, 3 depict one preferred embodiment of the flexible sealer. A trough 33 is set at outer wall of rotary valve 30 to accommodate the flexible sealer 60. Of which, the said trough 33 may be designed into a ring groove such that the sealer 60 forms an 0-ring.
Referring to Figure 8, the trough 33B is designed into a curved profile. The sealer 60B of the present invention is designed into a gasket.
Based upon above-specified structural design, the present invention is operated as follows: Referring to Figures 4, 5, when the button 50 is pulled up, through-hole 31 of the rotary valve 30 could be adjusted to align with inlet and outlet duct 41, 42 for an open state. In such case, the sealer 60 on outer wall of rotary valve 30 does not function.
Referring to Figures 6, 7, when through-hole 31 of rotary valve 30 is misaligned with inlet and outlet duct 41, 42, water supply is shut off. In such case, the sealer is positioned oppositely to outlet duct 42 to avoid any water leakage.
Referring also to Figures 9, 10, the flexible sealer can also be installed into outer wall of rotary valve 30 oppositely to inlet duct 41 of squirting gun body. So, when through-hole 31 of rotary valve 30 is positioned oppositely to inlet/outlet duct 41, 42, the water supply is shut off. In such case, the flexible sealer6O is positioned oppositely to inlet duct4l to avoid water leakage.
Figures 11, 12 depict another preferred embodiment of the flexible sealer: a circular flexible surface 70 (rubber) is covered onto outer wall of the rotary valve 30. And, a convex 71 is set at a preset location of this flexible surface 70. When through-hole 31 of the rotary valve 30 misaligns with inlet/outlet duct 4]., 42 (referring to Figures 6, 7), the convex 71 of the flexible surface 70 is positioned oppositely to inlet duct 41 (or outlet duct 42) to avoid water leakage.
Although a few preferred embodiments have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications might be made without departing from the scope of the invention, as defined in the appended claims.
Attention is directed to all papers and documents which are filed concurrently with or previous to this specification in connection with this application and which are open to public inspection with this specification, and the contents of all such papers and documents are incorporated herein by reference.
