Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model. Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, based on the embodiments of the utility model, which are apparent to those of ordinary skill in the art without inventive faculty, are intended to be within the scope of the utility model.

In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

As shown in fig. 1 to 6 and fig. 7 and 8, a toilet brush ring water spray head for eliminating a cleaning blind area is installed in an installation hole (not identified in the figure) at a step of a bowl mouth of a toilet bowl 40; the spray head comprises a spray pipe 10 with a flange plate 11 at the front end, wherein a main water channel 12 and a secondary water channel 13 which are communicated with the end surface of the flange plate 11 are axially and eccentrically arranged in a pipe cavity of the spray pipe 10; the spray head further comprises a surface cover 20 in wave soldering with the flange 11, and a pair of water cavities 30 are formed by the spacing space between the surface cover 20 and the end face of the flange 11.

Because the spray head and the flange plate 11 are assembled together in a welding mode, the thickness of the end part of the whole convex mounting hole (not marked in the figure) of the spray head is thinner, and the existing area of the cleaning blind area below the spray head is effectively shortened.

As shown in fig. 1, 2, 4, 5, 7 and 8, a main spout 21 is provided on the cover 20 to be axially connected to the main water channel 12, so that the main water channel 12 communicates with the main spout 21 to deliver water flow to the main spout 21. Because the main water channel 12 is axially biased to be arranged on the spray pipe 10, the main spray nozzle 21 is closer to the water-placing sliding surface along the urinal bowl mouth of the closestool 40 than the central position of the spray pipe 10, the spray nozzle height of the spray nozzle is reduced, and the problem of splash caused by overhigh spray nozzle height is avoided; furthermore, the height of the nozzle of the spray head is reduced, and the brush ring water flowing back and swiping can more easily reach the cleaning blind area below the spray head so as to flush and clean dirt (such as excrement, urine stain and the like) attached to the water-placing sliding surface of the bowl mouth of the toilet bowl 40.

As shown in fig. 1, 2, 4, 5 and 7, the flow diameter of the jet pipe 10 gradually decreases to the flow diameter of the main water channel 12, so that the water flow passes through the jet pipe 10 to reach the main jet opening 21, and the water pressure is increased, so that the flushing force of the water in the brush ring on the wall surface of the toilet bowl 40 is enhanced.

As shown in fig. 2, 3, 4, 5 and 7, a positioning groove 111 communicated with the auxiliary water cavity 30 is arranged on the end surface of the flange 11 in the radial direction, a positioning block 22 is arranged at the position of the positioning groove 111 of the face cover 20 under the main nozzle 21, and the positioning block 22 is sleeved into the positioning groove 111 to be matched with the main nozzle 21 to be axially aligned with the main water channel 12; the positioning block 22 and the axial clearance formed by the end surface of the flange 11 at the positioning groove 111 form a secondary nozzle 31; the positioning block 22 and the flange 11 form a sector ring shape with an axial gap at the positioning groove 111.

As shown in fig. 2, 3 and 7, an inner circular ring 211 communicated with the main nozzle 21 is convexly arranged on the back surface of the face cover 20, and an outer circular ring 121 communicated with the main water channel 12 is convexly arranged on the front surface of the flange 11; the inner ring 211 is inserted into the outer ring 121 to be sleeved and straight-through fit or the outer ring 121 is inserted into the inner ring 211 to be sleeved and straight-through fit; the utility model preferably adopts a mode of inserting the inner ring 211 into the outer ring 121 to realize the sleeve joint and direct connection fit; this not only enhances the sealing between the main spout 21 of the cover 20 and the main water channel 12 of the spout 10, but also separates the main water channel 12 from the sub water channel 13 so that the main water channel and the sub water channel do not interfere with each other at the sub water chamber 30.

The steps of assembling the spray head are as follows:

the positioning block 22 is axially aligned with the positioning groove 111 and is clamped together, so that two opposite sides of the positioning block 22 are abutted against the groove wall of the positioning groove 111, meanwhile, the inner circular ring 211 is inserted into the outer circular ring 121, the main water channel 12 is sleeved and connected with the main nozzle 21, a fan-shaped axial gap formed by encircling the positioning block 22 and the end face of the flange 11 at the positioning groove 111 forms a secondary nozzle 31 communicated with the secondary water cavity 30, then the spray pipe 10 and the face cover 20 are connected together in a wave soldering mode, and finally the spray pipe 10 is installed in a mounting hole (not marked in the figure) of a toilet 40 urinal step.

As shown in fig. 1, 4, 5 and 7, the through-flow caliber of the auxiliary water channel 13 is smaller than that of the main water channel 12, so that the water yield of the main nozzle 21 in the same unit time is larger than that of the auxiliary nozzle 31. The water flow sprayed by the main nozzle 21 along the axial direction of the spray pipe 10 is washed forward to form a backflow whirlpool, meanwhile, the auxiliary nozzle 31 synchronously sprays water flow downwards along the radial direction of the spray pipe 10, and the larger water flow sprayed by the main nozzle 21 and the smaller water flow sprayed by the auxiliary nozzle 31 are intersected in a cleaning blind area at the lower end of the auxiliary nozzle 31 so as to forcefully wash dirt attached to the inner wall of the urinal of the closestool 40, thereby being more beneficial to cleaning the closestool 40.

Moreover, because the brush ring water spray head of the closestool 40 is divided into low-pressure flushing and high-pressure flushing, when the low-pressure flushing is performed, the water pressure of brush ring water sprayed by the spray head is insufficient to form complete backflow swirling flow along the inner water retaining surface of the bowl mouth of the closestool 40, so that the cleaning blind area below the spray nozzle cannot be flushed and cleaned, but because the auxiliary spray nozzle 31 is additionally arranged, even in the low-pressure flushing state, the bowl mouth edge of the lower end of the brush ring can be flushed, so that the cleaning blind area is eliminated.

As shown in fig. 6 and fig. 4, fig. 5, fig. 7 and fig. 8, the outer ring 121 of the present utility model is located at the outlet of the auxiliary water chamber 30 facing the auxiliary nozzle 31, the water flow entering the auxiliary water chamber 30 from the auxiliary water channel 13 bypasses the outer ring 121 and flows to the auxiliary nozzle 31, and a karman vortex street effect is generated at the auxiliary nozzle 31, and as the auxiliary nozzle 31 is in a fan shape, the karman vortex is diffracted outwards while striking the wall surface of the positioning groove 111 and/or the end surface of the positioning block 22, a vortex surge with larger kinetic energy is generated, and by means of the vortex surge, the dirt on the water-retaining slide surface along the urinal bowl opening of the toilet 40 can be washed by the vortex, so that a better cleaning effect is achieved.

As shown in fig. 7 and 8, in this embodiment, the central axis of the secondary nozzle 31 is vertically and forward downward, that is, the secondary nozzle 31 extends radially along the nozzle 10. In other embodiments, the setting of the secondary nozzle 31 may be flexibly adjusted according to the flushing requirement of the user, and the axial center line of the secondary nozzle 31 may be designed to be biased toward the inner water blocking surface of the bowl mouth of the toilet 40 or biased toward the inner water blocking surface of the bowl mouth of the toilet 40; the mounting position of the secondary spouts 31 includes, but is not limited to, the above-described manner, as long as the secondary spouts 31 are not directed toward the buttocks of the user.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
