Detailed Description

Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.

the directions of "front", "back", "upper", "lower", etc. referred to herein are only for convenience of understanding, and the present invention is not limited to these directions, but may be modified according to the actual situation.

Referring first to fig. 1, an exploded view of a showerhead according to the present disclosure is shown.

As shown, the showerhead according to the present disclosure includes an upper body 70, a lower body 10, an upper decorative cover 100, each having a disk shape. The screw 90 passes through a hole in the upper body and is connected to a screw connection portion on the lower body 10 (see fig. 2, 3), thereby assembling the upper body 70 and the lower body 10 together, and the sealing gasket 80 forms a watertight seal at the junction of the screw 90 and the upper body 70. The junction of the upper body 70 and the lower body 10 is provided with a lower body gasket 20 to form a watertight seal. The upper decorative cover 100 covers the upper surface of the upper body 70, thereby forming the upper appearance of the shower head.

a sealed accommodating space is formed between the upper body 70 and the lower body 10, and the spring 30, the water outlet plug 40, the fixing plate 50 and the connecting member 60 are disposed in the accommodating space. The upper body 70 is provided with a water inlet for water to enter the receiving space.

The fixing plate 50 is shaped like a disk, has an area similar to that of the upper body 70 and the lower body 10, and can move up and down in the accommodating space. The spring 30 is disposed between the fixing plate 50 and the lower body 10, biasing the fixing plate 50 toward the upper body 70.

the connector 60 includes: an increased diameter portion 61 having a diameter larger than that of the hole 51 in the fixing plate 50; a plurality of elastic claws 62 provided on one side of the diameter-enlarged portion 61 and capable of being inserted from one side of the fixed plate 50 into the through holes 51 by elastic contraction and engaged with the other side of the fixed plate 50; and a connector 63 disposed at the other side of the diameter-increased portion 61 for connecting the water outlet plug 40.

The connecting member 60 passes through the fixing plate hole 51 in the fixing plate 50 to be engaged with the fixing plate 50. It should be noted that the connecting member 60 is not fixedly connected to the fixing plate 50, but there is a certain gap, that is, a snap-fit portion 64 is formed between the diameter-increased portion 61 and the elastic claw 62, the snap-fit portion 64 is snap-fit with the fixing plate, the height of the snap-fit portion 64 is greater than the thickness of the fixing plate 50, so that the connecting member 60 and the fixing plate 50 form a gap-fit in the water flow direction, and the connecting member 60 can move up and down relative to the fixing plate 50; the outer diameter of the clamping matching part 64 is matched with the inner diameter of the fixing plate hole 51, and the outer diameter of the clamping matching part 64 is smaller than the inner diameter of the fixing plate hole 51, so that the connecting piece 60 and the fixing plate 50 form clearance fit in the direction perpendicular to the water flow, and the connecting piece 60 can move left and right relative to the fixing plate 50. The outlet plug 40 and the connecting member 60 are collectively called an insertion fitting member, and the insertion fitting member is positioned to correspond to the outlet 11 of the lower body 10. The outlet plug 40 is connected to a lower end of the connector 60 and can be fitted into the outlet 11 of the lower body 10 (see fig. 2 and 3). One side of the lower body 10 close to the fixing plate 50 is fixedly provided with bosses 15 corresponding to the water outlets 11 one to one, the bosses 15 are provided with through holes communicated with the water outlets 11, and the diameter of each through hole is larger than or equal to that of each water outlet 11. The upper end surface 151 of the boss 15 is perpendicular to the axis of the water outlet 11, so that when the diameter-increased part 61 of the connecting piece 60 abuts against the upper end surface 151 of the boss 15, the connecting piece 60, the water outlet plug 40 and the water outlet 11 are coaxially matched.

Those skilled in the art will readily appreciate that the above-described configurations of the components are merely exemplary and that the present disclosure may be embodied in a wide variety of different forms. For example, the upper body 70 and the lower body 10 may be in the shape of a circular disc or a polygon, and the two may be connected by welding, bonding, or form fitting, so long as a sealed accommodation space can be formed. The shape of the fixing plate 50 may be designed to be the same as or different from the shapes of the upper and lower bodies 70 and 10 according to practical situations.

The upper body 70 has a tubular portion 71 at the center thereof. The tubular portion protrudes upwards from the upper surface of the upper body 70, wherein the hollow portion penetrates the upper body 70, forming a fluid communication between the outside and the housing space, so that the shower head can be supplied with water. The tubular portion 71 is provided with a threaded portion on its outer periphery.

with continued reference to fig. 1, a showerhead according to the present disclosure also has a body of water 110, a push rod 120, a ball joint washer 130, a ball joint 140, a bushing 150, a screen washer 170, and a showerhead nut 180.

The water outlet body 110 is located in the tubular portion 71, and has a water outlet groove 111 on a side wall, and the water outlet groove 111 forms a water inlet for water to enter the accommodating space. The push rod 120 is positioned in the water outlet body 110, and when water passes through, the push rod 120 opens the water outlet groove 111; when water is not being supplied, the push rod 120 closes the water outlet channel 111.

The ball joint gasket 130, the ball joint 140, the bushing 150, and the screen gasket 170 form a water supply structure of the shower head. The head nut 180 is coupled to the external thread of the tubular portion 71 of the upper body 70 to compress and hold the upper decorative cover 100, the water outlet body 110, the ball joint washer 130, the ball joint 140, the bushing 150, and the screen gasket 170.

the operation of the showerhead according to the present disclosure is described below in conjunction with fig. 2 and 3. FIG. 2 is a cross-sectional view of the showerhead according to the present disclosure, wherein the showerhead is in a water on state; fig. 3 is a cross-sectional view of a showerhead according to the present disclosure, wherein the showerhead is in a non-water on state.

As shown in fig. 2, when water is supplied, water flows into the water outlet body 110 from an opening at the lower part of the ball joint 140. The water pressure acts on the top of the push rod 120 which in turn applies a pushing force to the fixed plate 50 causing the fixed plate 50 to move downwardly against the bias of the spring 30 to its lower position.

It is noted that when the shower head starts to be supplied with water and the water amount is small, the push rod 120 does not expose the outlet groove 111 of the water body 110. Therefore, the water flow cannot reach the accommodating space between the upper body 70 and the lower body 10 through the water outlet body 110, but is collected on the push rod 120. As a result, the water flow generates sufficient pressure to move the push rod 120 downward, even at small water output.

when the push rod 120 moves downward, it exposes the outlet channel 111 of the water body 110, so that the water flow passes through the outlet body 110 from the ball joint 140 to the accommodating space between the upper body 70 and the lower body 10.

At this time, the connecting member 60 is, on the one hand, driven downward by the fixing plate 50 as it is fitted to the fixing plate 50, and, on the other hand, the connecting member 60 is designed to receive the pressure of the water flow by itself so as to be moved downward by the water pressure. Because the connecting piece 60 and the fixing plate 50 form clearance fit along the water flow direction, the enlarged part 61 is abutted against the boss 15 under the action of water flow, so that the water outlet plug 40 can be completely inserted into the water outlet 11 and completely matched with the water outlet, and the water splash is uniform; without the stopper being completely inserted into the water outlet 11 due to the bending deformation of the fixing plate 50. As a result of the downward movement of the connector 60, the water outlet plug 40 connected to the end of the connector 60 is fitted into the water outlet 11 of the lower body 10. Due to the structure of the outlet plug 40, the outlet plug 40 can be easily and stably fitted into the outlet 11 even if there is a certain manufacturing tolerance or under the influence of water flow. The specific structure of the water stopper 40 will be explained in detail later.

When the water outlet plug 40 is fitted into the water outlet 11, the water outlet 11 is defined as a fine water outlet passage having special properties, thereby forming a fine rain type water flow, and increasing the bathing experience of the user.

Turning now to fig. 3. When the water is not supplied, the water flow no longer flows from the ball joint 140 to the water outlet body 110, the water pressure no longer acts on the push rod 120, and the push rod 120 no longer applies a pushing force to the fixing plate 50. As a result, the fixing plate 50 moves upward under the bias of the spring 30 to its upper position. At this time, since the connecting member 60 is engaged with the fixing plate 50, the connecting member 60 is driven upward, so that the water outlet plug 40 also moves upward to be separated from the water outlet 11 of the lower body 10.

The spring 30 is plural and may be uniformly arranged in a circumferential direction around the center of the shower head.

Because the water outlet plug is no longer matched with the water outlet 11, the water outlet 11 is recovered to be a complete water outlet. At this time, the water accumulated in the accommodating space flows through the water outlet 11 rapidly and in a large amount, thereby effectively removing impurities and realizing a cleaning effect.

Turning now to fig. 4, an enlarged perspective view of the outlet plug 40 of a sprinkler according to the present disclosure is shown.

as shown, the outlet plug 40 has an approximately truncated cone shape tapering toward the outlet 11, and has a large diameter end and a small diameter end. The large-diameter end of the water outlet plug 40 is connected to the lower end of the connection member 60, and has a diameter greater than that of the lower end of the connection member 60. As a result, an annular portion of the upper surface of the outlet plug 40 is exposed to the outside of the connector 60.

The drain plug 40 includes a plurality of longitudinal grooves 42 and a plurality of circumferential grooves 43. The longitudinal slot 42 extends through the entire height of the water outlet plug 40 so as to define a passage through which the water flows. The longitudinal slot 42 has straight side walls and a smooth bottom. At the interface of the drain plug 40 and the connector 60, the bottom of the longitudinal groove 42 is flush with the outer surface of the connector 60. The circumferential groove 43 is located at the large diameter end of the water outlet plug 40 and is recessed downward. More specifically, the circumferential groove 43 is located approximately in the middle of the above-mentioned annular portion of the large-diameter end of the water outlet plug, and the circumferential groove 43 has a trapezoidal cross section. The circumferential groove 43 is interrupted by the longitudinal groove 42 and thus does not form a complete turn of the groove around the outlet plug 40. The water flow in the circumferential groove 43 acts on the circumferential groove 43, so that the water outlet plug 40 is pressed downwards by the water in the downward movement process.

the large diameter end of the outlet stopper 40 has a radially outwardly projecting lip 41. The lip edge 41 has a triangular radial cross section, the upper edge of the triangle is flush with the upper surface of the water outlet plug, the inner edge is integrated with the water outlet plug 40, and the outer edge forms an outward inclination angle relative to the side surface of the water outlet plug 40. The lip 41 is interrupted by the longitudinal slot 42 so that it does not form a complete ring around the outlet plug 40. The lip 41 is elastically engaged with the circumferential groove 43, and the lip 41 is elastically deformable into the circumferential groove 43 by an external force. The lip edge 41 has the advantages that water flows can only flow out from the longitudinal groove 42, and water splash is uniform and complete without splashing; meanwhile, as the lip edge 41 can elastically deform inwards, the friction force borne by the water outlet plug in the downward movement process is small, so that the water outlet plug 40 can also move in place under low pressure.

The lower body 10 has an outwardly inclined flared portion 12 at an upper edge of the water outlet 11. When the outlet plug 40 is fitted into the outlet 11, the lip 41 of the outlet plug 40 slides into and fits into the outlet 11 via the flared portion 12.

Due to the above structure of the water outlet plug 40 and the water outlet 11, even if there is a certain manufacturing tolerance or under the influence of water flow, the water outlet plug 40 can smoothly slide into the water outlet 11 and form a stable fit, so as to define an expected water flow channel and ensure good user experience.

The diameter of the water outlet 11 at the central position of the lower body 10 is greater than the diameter of the water outlet 11 at other positions of the lower body 10. The outlet plug 40 is sized to correspond to the size of the outlet 11.

while preferred embodiments have been shown and described herein, it should be understood that these embodiments are presented by way of example only. Numerous modifications, changes, and substitutions will occur to those skilled in the art without departing from the spirit of the invention. Accordingly, it is intended that the appended claims cover all such modifications as fall within the spirit and scope of the invention.
