Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and in particular to a water outlet device and a water tank. Background Technology

[0002] Currently, in addition to the water outlet that works with the drain, sinks also need to have an overflow outlet on their side wall. This is because when a user forgets to turn off the faucet and leaves with the drain closed, the water level in the sink will gradually rise. An overflow outlet on the side wall allows excess water to drain away, preventing water from overflowing the countertop. However, placing the overflow outlet directly on the side wall of the sink affects its internal appearance, and the overflow outlet is prone to accumulating dirt and grime, which, being exposed, also detracts from the overall aesthetics of the sink.

[0003] In addition, there are some rain shower or waterfall sprayers on the market that are installed on the sink basin. Their spray angle is fixed and they cannot rotate in multiple directions to clean food or tableware, which makes it difficult to meet the needs of users. Utility Model Content

[0004] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. To this end, the present invention proposes a water outlet device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

A spherical groove 150 is formed at the front end of the water passage cavity 140. The outer wall of the water inlet end of the water outlet head is provided with a spherical convex surface 210 that is adapted to the spherical groove 150. The spherical convex surface 210 is rotatably embedded in the spherical groove 150. The water outlet end of the water outlet head protrudes from the front end face of the housing 100. The overflow inlet 110 is located below the water outlet head.

[0032] In some embodiments of this utility model, there are two water outlets, two water inlets 130, and two water passage chambers 140. The two water outlets are arranged one above the other, and are respectively a waterfall water outlet 200 and a shower water outlet 300. The two water inlets 130 are respectively a waterfall water inlet 130 and a shower water inlet 130. The two water passage chambers 140 are respectively a waterfall water passage chamber 140 and a shower water passage chamber 140.

[0033] In some embodiments of this utility model, a mounting groove is provided on the spherical convex surface 210, and a sealing ring 211 is installed on the mounting groove. The sealing ring 211 abuts against the inner wall of the water outlet and the spherical groove 150. There is a small gap between the spherical convex surface 210 and the spherical groove 150. The sealing ring 211 is squeezed between the mounting groove and the inner wall of the spherical groove 150, filling this gap and forming a dynamic seal to prevent high-pressure water from leaking out from this rotating fit gap.

[0034] In some embodiments of this utility model, the housing 100 includes a water distribution body, a front cover plate 160, and a limiting seat 170. The front cover plate 160 is connected to the front end of the water distribution body. An overflow outlet 120 and a water inlet 130 are provided on the water distribution body. The water distribution body is provided with a first chamber 121 and at least one second chamber 141. An overflow inlet 110 is provided on the front cover plate 160. The overflow inlet 110 communicates with the overflow outlet 120 through the first chamber 121. The front cover plate 160 is provided with at least one third chamber. Chamber 142, second chamber 141, third chamber 142, and inlet 130 are connected one-to-one. Second chamber 141 and third chamber 142 form water passage chamber 140. Limiting seat 170 is embedded in third chamber 142. The rear end of limiting seat 170 abuts against the front end of water distribution body. The front end of limiting seat 170 has a first arc surface 151, and the front end of third chamber 142 has a second arc surface 152. The first arc surface 151 and the second arc surface 152 form a spherical groove 150. During installation, first install sealing ring 211 on the installation groove, then insert water outlet head into third chamber 142 from back to front, so that spherical convex surface 210 matches spherical groove 150, then insert limiting seat 170, and then weld the rear end of front cover plate 160 to the front end of water distribution body using ultrasonic circumferential sealing welding to complete the installation. Each component has a relatively independent and simplified shape, making it easier to mass-produce with high precision and low cost using molds, thus simplifying manufacturing and assembly.

[0035] In some embodiments of this utility model, the water distribution body is composed of a main shell 180 and a water distribution plate 190. An overflow outlet 120 and a water inlet 130 are provided on the main shell 180. The water distribution plate 190 is connected between the front cover plate 160 and the main shell 180. The water distribution plate 190 is provided with a first water passage 191 and a second water passage 192. The main shell 180 is provided with an overflow cavity 181 and at least one water inlet cavity 182. The water inlet cavity 182 is connected to the water inlet 130 one-to-one. The overflow cavity 181 is connected to the overflow outlet 120. The first water passage 191 and the overflow cavity 181 form a first chamber 121. The second water passage 192 and the water inlet cavity 182 form a second chamber 141. The combined structure of the main shell 180 and the water distribution plate 190 facilitates the construction of a relatively large chamber on the main shell 180 to reduce flow rate, noise and resistance. At the same time, on the relatively thin component of the water distribution plate 190, the first water passage 191 and the second water passage 192 enable efficient and precise guidance and strict isolation of water flow, reducing the manufacturing difficulty of the main shell 180.

[0036] In some embodiments of this utility model, a sealing gasket is also included. A perimeter 161 is provided around the front cover plate 160, and the sealing gasket is disposed on the rear end face of the perimeter 161. The sealing gasket is sandwiched between the front cover plate 160 and the side wall of the water tank 400 to prevent water in the water tank 400 from leaking out from the gap between the front cover plate 160 and the side wall of the water tank 400.

[0037] In some embodiments of this utility model, the rim 161 has screw mounting holes. The screw mounting holes enable the water outlet device to be securely installed on the water tank 400. When the screws are tightened, the rim 161 is evenly pressed against the side wall of the water tank 400 by the sealing gasket, forming a circumferential seal.

[0038] In some embodiments of this utility model, when there is only one water outlet, the protrusion length L1 of the water outlet end relative to the front face of the housing 100 is greater than the longitudinal distance L2 between the water outlet and the overflow inlet 110; when there are two or more water outlets arranged longitudinally, the overflow inlet 110 is located below the lowest water outlet, and the protrusion length L1 of the water outlet end relative to the front face of the housing 100 is greater than the longitudinal distance L2 between the lowest water outlet and the overflow inlet 110. The overflow inlet 110 is as close as possible to the water outlet, so that when the user observes from a normal usage perspective (standing or looking down), the water outlet can block the overflow inlet 110.

[0039] Reference Figure 6 A water tank 400 includes the aforementioned water outlet device.

[0040] In some embodiments of this utility model, a through hole is provided on the side wall of the water tank 400, and the water outlet device is installed in the through hole. Two mounting holes for mounting screws are also provided on the left and right sides of the through hole, and the left and right sides of the water outlet device are fixed to the water tank 400 by screws.
