Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] This utility model relates to a water outlet device, including a water sealing component 100, a water inlet channel 200, and a water cavity 300.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, the water outlet device is equipped with multiple inlet channels 200 and multiple water chambers 300, with each water chamber 300 and inlet channel 200 connected in a paired manner. Each inlet channel 200 can be connected in parallel to the same water supply channel 610. An external water supply system, such as a water pipe, can be connected to the water supply channel 610, and the water is distributed to each inlet channel 200 through the water supply channel 610. Each water chamber 300 is equipped with several outlet nozzles 400, and each water chamber 300 can have one, two, or more outlet nozzles 400. A water-sealing element 100 is installed on the connecting path between the inlet channels 200 and the water chambers 300. The water-sealing element 100 is used to control the opening and closing between the inlet channels 200 and the water chambers 300. The water-sealing element 100 has an elastic part 110, which undergoes elastic deformation under the change in water pressure of the incoming water flow. For example... Figure 3 and Figure 9 As shown, when the external water supply system supplies water to the inlet channel 200, the water pressure generated by the water flow increases and acts on the elastic part 110. The elastic part 110, under pressure, undergoes elastic deformation and opens, connecting the inlet channel 200 and the water cavity 300. Water flows from the inlet channel 200 through the sealing element 100 into the water cavity 300, and then is sprayed outwards from the corresponding outlet 400 in the water cavity 300. Figure 4 and Figure 9As shown, when the external water supply system stops supplying water to the inlet channel 200, the water pressure in the inlet channel 200 decreases, and the elastic part 110 elastically resets and closes, discontinuing the connection between the inlet channel 200 and the water chamber 300. After the elastic part 110 closes, the water chamber 300 forms a negative pressure relative to the external atmospheric pressure of the water nozzle, causing the water in the water chamber 300 to remain in the water chamber 300 and stop dripping out of the water outlet 400. The water outlet device achieves an immediate stop effect after the external water supply system is turned off. The overall structure of the water outlet device is simple, with multiple water chambers 300 for independent drainage. After the sealing element 100 closes, the water chambers 300 can retain sufficient residual water, allowing the negative pressure to more stably suppress the water flow and prevent dripping.

[0033] The water outlet device can be applied to water-using equipment such as spray guns and shower heads. This utility model also relates to a shower head, which includes a water outlet device and uses the water outlet device to realize the function of stopping the water flow when turned off.

[0034] In one embodiment, such as Figure 3 and Figure 4 As shown, the elastic part 110 includes a plurality of elastic petals 111 arranged sequentially along the circumference of the water-sealing component 100. The water-sealing component 100 as a whole can be made of elastic materials such as rubber or silicone, or the elastic petals 111 can be made of elastic materials such as rubber or silicone, while the other parts of the water-sealing component 100 except for the elastic petals 111 are made of rigid plastic. The number of elastic petals 111 can be three, four or more. In this embodiment, the elastic part 110 is provided with four elastic petals 111, and adjacent elastic petals 111 are cut and separated. When the external water supply system supplies water, the water pressure formed in the water inlet channel 200 is greater than the elastic deformation force of the elastic petals 111. The elastic petals 111 are elastically deformed towards the side where the water cavity 300 is located under the action of water pressure, and each elastic petal 111 separates from each other, forming a water passage gap 112 between each elastic petal 111. The water inlet channel 200 is connected to the water cavity 300 through the water passage gap 112. When the external water supply system stops supplying water, the water pressure in the inlet channel 200 is less than the elastic deformation force of the elastic flaps 111. Each elastic flap 111 elastically resets and fits together, thereby shutting off the connection between the inlet channel 200 and the water chamber 300.

[0035] In one embodiment, the water outlet device further includes a support member 500. For example... Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, the water cavity 300 has a first water inlet end 310, which is connected to the first water outlet end 210 of the water inlet channel 200. A water sealing element 100 is installed at the first water inlet end 310, and a support member 500 is installed in the water cavity 300. The support member 500 divides the interior of the water cavity 300 into multiple interconnected sub-cavities 320, each sub-cavity 320 having at least one corresponding water outlet 400. After the elastic part 110 opens, water flows from the first water outlet end 210 of the water inlet channel 200 to the first water inlet end 310 of the water cavity 300. The water flows into the support member 500 after passing through the water passage gap 112 formed by the elastic part 110, and then is distributed to each sub-cavity 320 by the support member 500, finally being sprayed outward from the corresponding water outlet 400 of each sub-cavity 320. Furthermore, the support member 500 is a hollow cylindrical shape, and the support member 500 may be open at both ends. The water-sealing component 100 is clamped between the first water inlet end 310 and one end of the support component 500. The other end of the support component 500 abuts against the cavity wall of the water cavity 300 opposite to the first water inlet end 310, thus fixing the water-sealing component 100. Multiple through holes 510 are provided on the peripheral wall of the support component 500. Water flows into the inner cavity of the support component 500 through the water passage gap 112, and then flows through the through holes 510 into the respective branch cavities 320. Specifically, the first water inlet end 310 is provided with a step 311, which extends from the edge or inner wall of the first water inlet end 310 towards the center. The circumferential edge of the water-sealing component 100 is provided with a slot 120, which abuts against the step 311, and one end of the support component 500 is inserted into the slot 120. By using the end of the support member 500 to cooperate with the slot 120, the periphery of the water sealing member 100 is supported, so as to prevent the water sealing member 100 from deforming after installation and causing the elastic part 110 to fail to close completely.

[0036] In one embodiment, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the water outlet device also includes a water distribution plate 600, a baffle plate 700, and a water outlet plate 800. The water distribution plate 600, baffle plate 700, and water outlet plate 800 are arranged sequentially, with the baffle plate 700 installed between the water distribution plate 600 and the water outlet plate 800. When the water outlet device is used in a shower head, the water distribution plate 600, baffle plate 700, and water outlet plate 800 can be locked into the shower head housing by screws or other means. Multiple water inlet channels 200 are defined between the water distribution plate 600 and the baffle plate 700. The water distribution plate 600 is provided with a water supply channel 610 that communicates with each water inlet channel 200. The water supply channel 610 is connected to an external water supply pipe, and water is distributed to each water inlet channel 200 through the water supply channel 610. Multiple water cavities 300 are defined between the partition plate 700 and the water outlet plate 800. A water outlet 400 is disposed on the water outlet plate 800 and can be integrally formed on the water outlet plate 800. A rib 720 extends from the side of the partition plate 700 facing the water outlet plate 800. The rib 720 is arranged in a closed loop facing the opening of the water outlet plate 800. The water outlet plate 800 seals the opening side of the space formed by the rib 720, thus forming the water cavity 300. The water distribution plate 600 has a main cavity 620, a first channel 630, and a second channel 640, all of which open towards the partition plate 700. Multiple first channels 630 extend circumferentially from the main cavity 620, and each first channel 630 extends into multiple second channels 640. The partition plate 700 covers one side of the water distribution plate 600. The partition 700 covers the openings of the main cavity 620, the first branch channel 630, and the second branch channel 640. The partition 700 and the second branch channel 640 form an inlet channel 200, the partition 700 and the main cavity 620 form a supply channel 610, and the partition 700 and the first branch channel 630 form a branch channel 650 connecting the inlet channel 200 to the supply channel 610. Water flows into the supply channel 610 and then branches into the branch channels 650, and from the branch channels 650 it branches back into the corresponding inlet channels 200.

[0037] Furthermore, a column 710 extends from the partition 700 toward the side of the water distribution plate 600. The column 710 has openings at both ends and forms the first water inlet 310 of the water cavity 300. The end of the second channel 640 is sleeved on the column 710, which connects the water inlet channel 200 and the water cavity 300, thus achieving the connection between the water inlet channel 200 and the water cavity 300. The sealing element 100 can be installed in the column 710.

[0038] The water outlet 400 can be configured to maintain communication with the water chamber 300. Alternatively, in this embodiment, as shown... Figure 9As shown, the wall of the water cavity 300 is provided with multiple grooves 330, the number of which is the same as the number of water outlets 400 provided in the water cavity 300. Each water outlet 400 has a second inlet end 410 and a second outlet end 420. The second inlet end 410 is located in the water cavity 300, and the second outlet end 420 extends outside the water cavity 300. The second inlet end 410 can elastically expand and contract relative to the central axis of the water outlet 400, and each second inlet end 410 is paired and inserted into a groove 330. When the elastic part 110 is closed, the periphery of the second outlet end 420 can elastically open outward to abut against the groove wall of the groove 330, further preventing water from flowing from the water cavity 300 to the water outlet 400. When the water inlet channel 200 supplies water to the water chamber 300, the water pressure in the water chamber 300 acts on the second water inlet end 410. The second water inlet end 410 is elastically contracted by the water pressure and leaves the groove wall of the groove 330, thereby connecting the water outlet 400 with the water chamber 300.
