The present invention relates to a nozzle for spraying liquid, more particularly, a nozzle structure that can seal the water when rotated to the end position in a forward or reverse direction.
It is known that a general sprinkler is composed of at least a nozzle and a water pipe (not shown), the nozzle comprises a nozzle head A and a nozzle cover B, wherein the rear end of the nozzle head A is connected to the water pipe and the front end is provided with at least one water outlet A1, also a guiding member A2 is installed at the front end; the front end of the nozzle cover B has at least one water spout B1, and the nozzle cover B is sleeved on the nozzle head A which can be rotated on the nozzle head A to adjust the relative distance between the guiding member A1 of the nozzle head A and the water spout B1, so that the water sprayed from the water spout B1 can be adjusted back and forth between scattering or direct-jetting, meanwhile; a sealing washer B2 (as shown in
However, when the user has adjusted the nozzle cover B to the direct water jet with maximum volume and required it to be turned off, the nozzle cover B will have to be rotated back to the end position corresponding to the nozzle head A, so it cannot be turned off immediately, and if the user is not familiar with the nozzle and tries to adjust the nozzle cover B from a small volume of the scattering water to the maximum volume of the direct water jet, but still cannot turn off the water flow, later found out that it has been turned in the wrong direction and has to rotate the nozzle cover B back to the end position corresponding to the nozzle head A again, which is really time-consuming and laborious.
Therefore, how to improve the above deficiencies and provide a nozzle structure or device that can be turned off immediately is a technical issue that the inventor of the present disclosure intends to solve.
The purpose of the present disclosure is to provide a nozzle structure with forward and reverse water sealing, which is composed of at least a nozzle head, a cover, and a plurality of sealing rings. The two ends of the nozzle head are the water-filling end and the spraying end respectively, wherein, at least one drainage aperture is pierced on the side of the spraying end and a guide cone is provided at the upper end of the spraying end, a stopper is installed convexly on the outer periphery at the end portion of the spraying end, and the cover is sleeved on the nozzle head which is able to rotate forwardly and reversely. The sealing rings are divided into at least first, second, and third sealing rings and are set on the nozzle head and the cover respectively. The first sealing ring is set relatively on the rear of the drainage aperture of the nozzle head and can be attached to the inner side of the cover, the second sealing ring is set relatively between the upper end of the spraying end of the nozzle head and the guide cone and can be attached to the water spout of the cover correspondingly, and the third sealing ring is set relatively on the inner middle section of the cover and can be attached to the stopper of the nozzle head. When the cover is rotated to the forward end or reverse end on the nozzle head, both ends of the cover can be sealed by the first and second sealing rings or the first and third sealing rings to achieve the purpose of sealing off the water.
To achieve the above purpose, a screwed joint is provided on the outer side of the middle section of the nozzle head, and another screwed joint is provided on the bottom inner side of the cover, so that the cover can be sleeved on the nozzle head correspondingly and rotated forwardly and reversely to adjust the relative distance between the guide cone and the water spout.
In order to achieve the above or other purposes and efficacy, the technical means and structures employed in the present disclosure are illustrated and described in detail as follows with respect to the preferred embodiments of the present disclosure for a complete understanding of their features and functions.
Referring to
When the present disclosure is in use, any water pipeline can be connected to the water-filling end 101 of the nozzle head 1 to supply the water into the nozzle head 1 and output from the drainage aperture 11 on the spraying end 102 of the nozzle head 1. The cover 2 is sleeved on the nozzle head 1 and can be rotated in the forward or reverse direction to adjust the relative distance between the guide cone 12 of the nozzle head 1 and the water spout 21 of the cover 2. The water flow from the nozzle head 1 drainage aperture 11 is flowing through the guide cone 12, then sprays out from the water spout 21 of the cover 2, so that the water jet from the water spout 21 can be adjusted between scattering and direct jetting states, and when the cover 2 rotates to the forward end or reverse end, the first sealing ring 3 and the second sealing ring 4, or the first sealing ring 3 and the third sealing ring 5, can be sealed at both ends of the cover 2, reach the purpose of sealing the water by rotating the cover 2 to the forward end or reverse end.
In addition, when using the nozzle structure of the present disclosure to spray the water, the user can choose to rotate the cover 2 in a forward or reverse direction according to the spraying state of the water spout 21 and quickly rotate to the forward or reverse end of the nozzle head 1, so that the first and second sealing rings 3 and 4, or the first and third sealing rings 3 and 5 can seal both ends of the cover 2 to achieve the effect of water sealing and water shutting.
Regardless of the state of the water jet from the water spout 21, the first sealing ring 3 on the drainage aperture 11 of the spraying end 102 of the nozzle head 1 has remained close to the inner side of the cover 2, so that the seal between the bottom end of the cover 2 and the nozzle head 1 can be maintained.
When the water sprayed from the water spout 21 is in a scattering state, the user can turn the cover 2 in the forward direction corresponding to the nozzle head 1 and quickly turn it to the forward end of the nozzle head 1, so that the second sealing ring 4, which is set between the upper end of the spraying end 102 of the nozzle head 1 and the guide cone 12, can attach to and seal with the water spout 21 of the cover 2 (as shown in
In view of the above and refer to
When the water sprayed from the water spout 21 is in a direct-jetting state, the user can turn the cover 2 in the reverse direction corresponding to the nozzle head 1 and quickly turn it to the reverse end of the nozzle head 1, so that the third sealing ring 5, which is set in the inner middle section of the cover 2, can attach to and seal with the stopper 13 around the spraying end 102 of the nozzle head 1 (as shown in
In view of the above and refer to
In addition, even if the user is not familiar with the nozzle structure of the present disclosure, also can rotate the cover 2 to the end in either direction on the nozzle head 1, so that the first sealing ring 3 and the second sealing ring 4 (or the first sealing ring 3 and the third sealing ring 5) can seal the two ends of the cover 2, stop the water flow for spraying and achieve the effect of easy to use.
In summary, compared to the various shortcomings and unsolvable problems of the nozzle of conventional sprinklers, the present disclosure uses a special design of nozzle head 1, cover 2, first sealing ring 3, the second sealing ring 4, and third sealing ring 5, so that the cover 2 can be optionally rotated to the end corresponding to the nozzle head 1 in the forward direction or the reverse direction, and quickly seals the two ends of the cover 2 to stop the water, so as to achieve the efficacy and purpose of easy use.
However, the above is only the preferred embodiment of the present disclosure, and it does not limit the scope of the patent of the present disclosure. Therefore, all simple modifications and equivalent structural changes made by applying the contents of the specification and drawings of the present disclosure shall be included in the scope of the patent of the present disclosure.
