Modes for Carrying Out the Invention

[0017] The technical solution in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] The conventional pulsed water discharge structure has problems such as a large number of components such as a water distribution tray and high manufacturing costs.

[0019] To solve the above technical problems, the present embodiment provides a pulsed water discharge structure and a shower head. Referring to FIG. 1, FIG. 1 is a cross-sectional view of the pulsed water discharge structure in the embodiment.

[0020] The pulsed water discharge structure of the present embodiment includes a shell 1.

[0021] The shell 1 is provided with a water inlet 101, a water supply hole 102, a water discharge hole 103, and a water discharge cavity 105. There are at least two water supply holes 102, which communicate with the water inlet 101. An impeller assembly 3 is provided at the water inlet 101. The impeller assembly 3 is configured to cover the water supply holes 102 in sequence. The water supply hole 102 and the water discharge hole 103 communicate with the water discharge cavity 105.

[0022] The shell 1 may be a split structure and function as a carrier for installing the impeller assembly 3. Here, the water inlet 101 is used to introduce water flow, and the impeller assembly 3 alternately allows the water flow to flow into each water supply hole 102 by covering the water supply holes 102 in sequence, thereby forming a pulsed water flow. The number of the water discharge cavity 105 and the water supply hole 102 may be the same and correspond one-to-one.

[0023] When the pulse water discharge structure in the above technical solution is operating, water flows into the water inlet 101, and the impeller assembly 3 covers each water supply hole 102 in turn, so that the water flow alternately flows into each water discharge cavity 105, and the water flow in the water discharge cavity 105 flows out from the water discharge hole 103 to form a pulse water flow. Compared with the conventional pulse shower head, the pulse water discharge structure does not require a plurality of water distribution trays, so the number of parts is reduced, which helps to reduce the manufacturing cost.

[0024] In the related art, since the water supply holes of the pulse shower head are directly communicated with the water discharge cavities, and the water discharge holes are evenly distributed in the water discharge cavities, the water discharge amount from the water discharge holes arranged opposite to the water supply holes increases, while the water discharge amount from the other water discharge holes arranged on the outside gradually decreases, resulting in variations in the water discharge intensity from each water discharge hole.

[0025] Referring to FIGS. 2 and 3, FIG. 2 is a cross-sectional view of the pulse water discharge structure with a water leveling plate in the embodiment, and FIG. 3 is an exploded view of the pulse water discharge structure with a water leveling plate in the embodiment. The pulse water discharge structure of this embodiment further includes a water leveling plate 2 provided in the shell 1. The two surfaces of the water leveling plate 2 form a water passing cavity 104 and a water discharge cavity 105 together with the inner side of the shell 1 respectively, and a water passing hole 20 for communicating the water passing cavity 104 and the water discharge cavity 105 is provided. There are at least two water passing cavities 104, which are separated from each other. Each water passing cavity 104 communicates with the water inlet 101 through different water supply holes 102. The water discharge cavity 105 communicates with the water discharge hole 103.

[0026] The above water leveling plate 2 is used to form the water passing cavity 104 and the water discharge cavity 105 inside the shell 1. The water passing cavity 104 is used to buffer the water flow flowing out from the water discharge hole 103 and prevent it from directly flowing into the water discharge cavity 105. Here, the water passing hole 20 and the water discharge hole 103 may be evenly arranged in the water passing cavity 104 and the water discharge cavity 105 respectively.

[0027] When the pulse water discharge structure with the water leveling plate is operating, water flow enters through the water inlet 101, and the impeller assembly 3 alternately covers each water supply hole 102, causing the water flow to alternately enter each water passage cavity 104. Subsequently, the water flow in the water passage cavity 104 enters the water discharge cavity 105 through the water leveling holes, and the water flow in the water discharge cavity 105 flows out through the water discharge holes 103 to form a pulse water flow. Here, the water flow from the water supply holes 102 does not directly flow into the water discharge cavity 105 as in the prior art. Instead, it is buffered and equalized pressure by the water leveling cavity and then flows into the water discharge cavity 105. Therefore, the water discharge intensity from each water discharge hole 103 becomes more uniform. Thus, it can be seen that the pulse water discharge structure of this embodiment can effectively improve the uniformity of the water discharge intensity of each water discharge hole 103 and improve the water discharge effect and the user experience.

[0028] In an embodiment where the two surfaces of the above-mentioned water leveling plate 2 together with the inside of the shell 1 form the water passage cavity 104 and the water discharge cavity 105 respectively, the shell 1 includes a water distribution component 11 and a water discharge component 12. Spaces are provided inside the water distribution component 11 and the water discharge component 12. The water distribution component 11 and the water discharge component 12 may be directly connected or indirectly connected through the water leveling plate 2. The water leveling plate 2 is fixed between the water distribution component 11 and the water discharge component 12 by clamping or adhesion. One surface of the water leveling plate 2 together with the water distribution component 11 forms the water passage cavity 104, and the other surface together with the water discharge component 12 forms the water discharge cavity 105.

[0029] In one embodiment where the above-described impeller assembly 3 is disposed within the water supply port 101, the water distribution component 11 includes a shaft portion 112 at the central portion of the water supply port 101, and the shaft portion 112 may be integrally formed on the water distribution component 11. The impeller assembly 3 includes a rotating blade 31 and an inclined water delivery plate 32. The rotating blade 31 is provided with a fitting hole 301, and is movably fitted to the shaft portion 112 through the fitting hole 301 so as to be rotatable around the shaft portion 112. The rotating blade 31 is provided with a closing portion 302 configured to cover the water supply hole 102 and an opening portion 303 configured to open the water supply hole 102, and the opening portion 303 may be a clearance. The inclined water delivery plate 32 is provided on the side of the rotating blade 31 away from the water supply hole 102, and is provided with an inclined water delivery hole 304 disposed obliquely. When the impeller assembly 3 is operating, water flows vigorously from the inclined water delivery hole 304 to the rotating blade 31, rotating the rotating blade 31. During the rotation of the rotating blade 31, each water supply hole 102 is sequentially covered by the closing portion 302 and sequentially opened by the opening portion 303, so that the water flow in the water supply hole 101 alternately flows into the water discharge hole 103, forming a pulsed water flow.

[0030] It will be understood that the above-described embodiment of the impeller assembly 3 also includes an existing pulse assembly for forming a pulsed water flow.

[0031] In one embodiment where the above-described water discharge component 12 and the water leveling plate 2 form the water discharge cavity 105, the water discharge component 12 is provided with a peripheral portion 121 and a rib 122 located inside the peripheral portion 121. The peripheral portion 121 and the rib 122 may be integrally connected to the water discharge component 12. The rib 122 divides the space inside the peripheral portion 121 into at least two chambers. The water leveling plate 2 covers the chambers and forms the same number of water discharge cavities 105 as the chambers.

[0032] As shown in FIG. 4 which is a perspective view of the water distribution component in the embodiment, the implementation method in which the above-described water distribution component 11 and the water leveling plate 2 form the water leveling cavity may be the same as the implementation method in which the above-described water discharge component 12 and the water leveling plate 2 form the water discharge cavity 105, so it will not be repeated here.

[0033] In this embodiment, the numbers of the water supply holes 102, the water passage cavities 104, and the water discharge cavities 105 are the same and are arranged in a one-to-one correspondence, that is, one water supply hole 102 corresponds to one water passage cavity 104 and one water discharge cavity 105.

[0034] Referring to FIG. 5, FIG. 5 is a cross-sectional view of the shower head in the embodiment. This embodiment provides a shower head having the above-described pulsed water discharge structure fixed between the housing and the face cover of the shower head, and the water inlet 101 communicates with the water supply channel of the shower head. By applying the pulsed water discharge structure, the shower head of this embodiment can effectively improve the uniformity of the water discharge intensity of each water discharge hole 103 and improve the water discharge effect and the use experience.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. Also, the scope of the present invention is limited by the appended claims and their equivalents.
