Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a water outlet device and drinking water equipment. Background Art

[0002] At present, there are vertical air-purifiers and heat-sinks on the market. After users take hot water, there is still water dripping from the water outlet, which often burns the users' hands.

[0003] To this end, the Chinese patent application number CN202321088704.X "A solenoid valve assembly and water dispenser for drinking water equipment" is provided with a vent hole that penetrates the wall thickness and is connected to the drainage chamber on the vertical extension section of the drain pipe. According to the direction of water flow, the vent hole is located downstream of the solenoid valve. After the solenoid valve is closed, the outside air enters the drainage chamber through the vent hole. In this way, under the action of atmospheric pressure and gravity, no water column will remain in the vertical extension section, and thus there will be no dripping or water flowing out in streams.

[0004] However, in the above solution, hot water may overflow through the vent hole and splash onto the user. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a water outlet device which can avoid water splashing during the water supply process and can avoid water dripping at the water outlet after the water supply is stopped, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a drinking water device using the above-mentioned water outlet device.

[0007] The technical solution adopted by the utility model to solve the first technical problem mentioned above is: a water outlet device, including a pipe body with an exhaust port on the side, characterized in that: it also includes an exhaust pipe, the inlet of the exhaust pipe is connected to the exhaust port, and an elastic hose is installed in the exhaust pipe, the elastic hose includes an outer tube and an inner tube arranged in the outer tube, the outer peripheral wall of the outer tube is sealed with the inner peripheral wall of the exhaust pipe, and the periphery of the inner tube has a convex edge connected to the inner peripheral wall of the outer tube, so that an annular groove with a bottom opening is formed between the inner tube, the outer tube and the convex edge.

[0008] In order to facilitate the processing of the flange, the peripheral edge of the top of the inner tube is bent and extended outward to form the flange.

[0009] In order to support the outer tube, a rigid tube is installed inside the outer tube, and the outer peripheral wall of the rigid tube is closely attached to the inner peripheral wall of the outer tube.

[0010] In order to clamp the elastic hose in cooperation with the rigid pipe, a clamping ring for clamping the elastic hose is sleeved at a position on the outer circumference of the exhaust pipe corresponding to the rigid pipe.

[0011] In order to avoid interference between the rigid tube and the inner tube, the rigid tube is located above the inner tube.

[0012] In order to improve the installation stability of the rigid tube, the end surface of the bottom end of the rigid tube abuts against the convex edge.

[0013] In order to ensure that water flows out smoothly, the pipe body is arranged vertically.

[0014] In order to increase the water flow rate and simplify the structure at the same time, the number of the pipe bodies is two, and the two pipe bodies share the same water outlet section and exhaust port.

[0015] In order to achieve a reasonable arrangement of the exhaust port, the water outlet section of the pipe body is arranged vertically, and the water inlet section of the pipe body is arranged obliquely, and the exhaust port is located at the junction of the outlets of the two water inlet sections of the pipe body.

[0016] The technical solution adopted by the utility model to solve the second technical problem is: a drinking water device using the above-mentioned water outlet device.

[0017] Compared with the prior art, the utility model has the following advantages: an elastic hose consisting of an outer tube and an inner tube is installed in the exhaust pipe, and a convex edge connected to the inner peripheral wall of the outer tube is arranged on the periphery of the inner tube, so that an annular groove with a bottom opening is formed between the inner tube, the outer tube and the convex edge. In this way, during the water supply process, the inner tube will be squeezed by the water pressure in the groove, and the fine holes inside the inner tube will be blocked at this time. At the same time, because the water outlet of the tube body is always open, hot water will flow out from the water outlet first; after the water supply is stopped, the external force on the inner tube is eliminated, and the fine holes inside the inner tube are completely opened. At this time, the inside of the tube body is connected to the atmospheric pressure, and the water inside will instantly flow out through the water outlet. The inside of the tube body is in a waterless state at this time, so the problem of dripping from the faucet is solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0023] Embodiment 1:

[0024] like Figure 1 and Figure 2 The figure shows the first preferred embodiment of the drinking water equipment with a water outlet device of the utility model. The water outlet device comprises a pipe body 1, an exhaust pipe 2, an elastic hose 3, a rigid pipe 4 and a clamp ring 5.

[0025] The pipe body 1 is arranged vertically. Specifically, the water inlet at the top of the pipe body 1 is used to connect to the water outlet of a pressureless electromagnetic valve (not shown in the figure); the water outlet at the bottom of the pipe body 1 is used to connect to a water outlet nozzle (not shown in the figure); and an exhaust port 11 is opened on the side of the pipe body 1.

[0026] The inlet at the bottom end of the exhaust pipe 2 is connected to the exhaust port 11, and the end section of the exhaust pipe 2 is arranged vertically.

[0027] The elastic hose 3 is made of silicone and is installed in the inner cavity of the end section of the exhaust pipe 2. Specifically, the elastic hose 3 includes an outer tube 31 and an inner tube 32 arranged in the inner cavity at the lower part of the outer tube 31. The outer peripheral wall of the outer tube 31 is tightly attached to the inner peripheral wall of the exhaust pipe 2 and is sealed. The peripheral edge of the top of the inner tube 32 is bent outward and extended to form a convex edge 321. The convex edge 321 is connected to the inner peripheral wall of the outer tube 31, so that an annular groove 322 with a bottom opening is formed between the inner tube 32, the outer tube 31 and the convex edge 321.

[0028] The rigid tube 4 is installed in the inner cavity of the upper part of the outer tube 31, that is, located above the inner tube 32. Specifically, the outer peripheral wall of the rigid tube 4 is closely attached to the inner peripheral wall of the outer tube 31, and the end surface of the bottom end of the rigid tube 4 abuts against the convex edge 321. The rigid tube 4 can play the role of a skeleton to support the outer tube 31.

[0029] The clamping ring 5 is sleeved on the outer circumference of the exhaust pipe 2 at a position corresponding to the rigid pipe 4 , and is used to cooperate with the rigid pipe 4 to clamp the elastic hose 3 .

[0030] Embodiment 2:

[0031] like Figure 3As shown, it is the second preferred embodiment of the drinking water equipment with a water outlet device of the utility model. The difference from the embodiment 1 is that:

[0032] In this embodiment, there are two pipe bodies 1 , and the two pipe bodies 1 share the same water outlet section and exhaust port 11 .

[0033] Specifically, the two pipe bodies 1 are arranged symmetrically relative to the vertical plane, the water outlet section of the pipe body 1 is arranged vertically, and the water inlet section of the pipe body 1 is arranged obliquely, and the exhaust port 11 is located at the connection between the outlets of the water inlet sections of the two pipe bodies 1.

[0034] The reason for this design is that the water flow rate of the pressureless solenoid valves currently used in the market is generally 3.5L / min, but some users require the water flow rate to be greater than 6L / min, so this embodiment uses two pressureless solenoid valves in parallel to meet the water flow rate requirements.

[0035] Taking Example 1 as an example, the working principle of the utility model is as follows:

[0036] (1) When the pressureless solenoid valve is opened, hot water will flow into the pipe body 1 from the water outlet of the pressureless solenoid valve. At this time, there will be a certain water outlet pressure inside the pipe body 1, and this pressure can react on the elastic hose 3. Since the elastic hose 3 is a double-layer silicone sleeve, there is a pore in the middle of the inner tube 32, which is connected to the atmosphere. However, when the pressureless solenoid valve is opened, the inner tube 32 will be squeezed by the water pressure in the groove 322, and the pore will be blocked. At the same time, because the water outlet of the pipe body 1 is normally open, the hot water will flow out from the water outlet first;

[0037] (2) When the pressure-free solenoid valve is closed, the external force on the inner tube 32 is eliminated, and the middle pore is fully opened. At this time, the inside of the tube body 1 is connected to the atmospheric pressure, and the water inside will instantly flow out through the water outlet. At this time, the inside of the tube body 1 is in a water-free state, so the problem of water dripping from the faucet is solved.
