Description

Dirt-proof rotary spray head

Technical Field

The utility model relates to the technical field of kitchen and bathroom instruments, in particular to a dirt-proof rotary spray head.

Background

At present, since the assembling position of the pressure lever is located in the middle of the spray head or below the position of the water outlet hole of the spray head, after the rotary spray head is used, accumulated water or water drops can flow downwards along the end part of the spray head and flow to the assembling position of the pressure lever or the assembling corner of the pressure lever, and then the accumulated water or the water drops can accumulate (stay) at the assembling corner. When the rotary spray head cleans a cup, some dirt on the cup is flushed by means of water flow impulse, water left after cleaning is not pure water, and scale can still be generated on the rotary spray head.

We found that in the existing rotary spray head design, scale is very easy to be generated due to the installation groove position below the spray head water outlet hole, particularly the press rod assembly position, and therefore, the disadvantage that the press rod is assembled at the middle part of the spray head is the problem of scale.

The technical problems to be solved are as follows: how to overcome the problems of scale accumulation or difficult cleaning at the grooves and the gaps of the assembly structure.

Detailed Description

Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be noted that the following embodiments and features in the embodiments may be combined with each other without conflict.

It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.

The following describes embodiments of the present utility model in further detail with reference to FIGS. 1-5.

Examples:

an antifouling rotary spray head, as shown with reference to figures 1, 2 and 3, comprises a nipple 1, a valve body 2, a valve stem 3, a nozzle 4 and a spring 5. The adapter 1 is used for being installed and fixed at a basin and the like. The valve body 2 is inserted and fixed at the upper end of the adapter tube 1, the valve rod 3 is inserted and assembled at the lower end of the valve body 2 for opening and closing the water flow path, and as can be seen in fig. 5, the lower end of the valve rod 3 is connected with the first sealing member 8, and the lower end is provided with a water inlet hole 31, when the valve rod 3 moves down, the lower end of the adapter tube 1 supplies water, and enters from the water inlet hole 31 and is ejected from the upper end of the nozzle 4. The water flow impulse is utilized to realize the rotary water spraying or inclined water column water spraying of the nozzle 4, so as to clean the inner wall of the cup.

This scheme, nozzle 4 adopts the structure of integral type, nozzle 4 direct fixation has cup jointed spring 5 on valve rod 3 in the upper end of valve rod 3, and the one end of spring 5 is contradicted in the lower extreme of case body 2, and the other end of spring 5 is contradicted in the lower extreme of nozzle 4, is provided with seal structure on the lower extreme of nozzle 4 and the inner wall contact surface of case body 2, and the up end of nozzle 4 is hemisphere face 41, is provided with straight hole 42 and inclined hole 43 on the hemisphere face 41, and hemisphere face 41 below sets up the helicitic texture 44 that supplies press bar 6 to assemble. The action of the spring 5 serves to provide a return force and to keep the valve stem 3 in a water cut-off action, i.e. to keep no water out in the initial state. Only, through pressing operation for push rod 6 moves down, drives valve rod 3 and moves down, thereby opens the water inlet channel, realizes the play water.

In order to further overcome the problem of easy cleaning and the problem of installation, a limiting ring 45 is arranged below the threaded structure 44 of the nozzle 4, and the upper end surface of the limiting ring 45 is used for supporting the pressing rod 6. In the figures the thread profile is not shown, but it is understood that the thread design here allows the pressing rod 6 to be fixed by means of the thread structure 44. Or the fixation may be achieved by fastening. Here, the stop collar 45 may play a role in stopping, indicating that the installation is already firm when the pressing rod 6 abuts against the stop collar 45. Therefore, the structure is tightly assembled, thus water accumulation is not easy to generate, and the dead angle position below the structure is not easy to generate water accumulation through shielding of the pressing rod 6, and the structure is easy to clean if foreign matters are stuck.

Further, in order to facilitate assembly, the mounting and fastening are excessive, a ring groove 46 is provided between the screw structure 44 and the stop collar 45, and the upper wall of the ring groove 46 is inclined. Thus, the cleaning function can be easily disassembled, and the pressing rods 6 with different sizes can be conveniently replaced.

In order to improve the reliability of the seal, the seal structure includes two seal grooves 47 provided at the neck of the nozzle 4, and an upper seal ring 48 fitted in the seal grooves 47. The double sealing mode is adopted, so that the assembly tightness degree is greatly improved, and water leakage is avoided.

In order to facilitate cleaning and up-down pressing operations, the bottom surface of the retainer ring 45 is parallel to the upper end surface of the valve body 2, and a movable space 7 is formed therebetween. The movable space 7 is opened on the side, so that the cleaning and the treatment are easy, and the cleaning operation is easy due to the parallel upper and lower surfaces.

The above embodiments are merely illustrative of the principles of the present utility model and its effectiveness, and are not intended to limit the utility model. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the utility model. Accordingly, it is intended that all equivalent modifications and variations of the utility model be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
