Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment technology, and specifically relates to a tea bar machine anti-drip water dispensing structure. Background Technology

[0002] In the contemporary home and commercial water supply equipment sector, tea bar machines, with their integrated hot water supply, heat preservation, and intelligent control functions, have become an important solution for meeting immediate drinking water needs. These devices typically feature a vertically downward-facing water outlet, with a tubular structure made of stainless steel or food-grade plastic, suspended approximately 10-15 cm above the work surface to collect water from containers such as kettles. Due to the inherent physical properties of drinking water, residual dripping after the water dispensing process is a significant technical challenge. The droplet formation mechanism stems from multiple fluid dynamics effects: on one hand, the solid-liquid interfacial tension between water molecules and the pipe wall material (especially smooth metal or plastic surfaces) causes the liquid to rise along the pipe wall; on the other hand, the curved structure at the outlet end exacerbates the meniscus effect, causing liquid to accumulate at the pipe edge. When the accumulated liquid mass exceeds the adhesion force between the liquid film and the pipe wall, it forms a droplet under the influence of gravity. This phenomenon is particularly pronounced at high temperatures—the surface tension of hot water above 80°C is about 20% lower than that of cold water, increasing its fluidity and making residual liquid more prone to coalescing and dripping.

[0003] This dripping problem causes multiple secondary hazards: the dripped liquid first forms water stains on the stainless steel or glass work surface of the tea bar machine, and the dissolved calcium and magnesium ions leave white residue after evaporation, affecting the appearance of the equipment. More seriously, the humid environment provides ideal conditions for microbial growth, and the long-term residual wet area can breed biofilm, forming a source of pollution that is difficult to remove. Utility Model Content

[0004] This utility model aims to provide a drip-proof water outlet structure for tea bar machines, mainly to solve the technical problem that, after the conventional structure of the water outlet of a tea bar machine has finished draining, droplets easily form on the surface of the tea bar machine, causing surface contamination.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A drip-proof water outlet structure for a tea bar machine includes an outlet for discharging drinking water, and an outlet head installed on the outlet to prevent water droplets from falling after the water is stopped. The outlet head includes a mounting cap connected to the outlet, and an elastically deformable rubber tube is connected to the end of the mounting cap away from the outlet. The end of the rubber tube away from the mounting cap is processed into a duckbill shape and is in a closed state when not subjected to external force.

[0007] Preferably, the water outlet is threadedly connected to the mounting cap.

[0008] Preferably, the surface of the end of the rubber tube furthest from the mounting cap is roughened.

[0009] Preferably, the rubber tube has two rigid, symmetrically arranged, mutually fitting closing tabs fixed at the end away from the mounting cap. The end of the closing tab group away from the rubber tube is machined into a blade shape. The closing tab group includes a first closing tab and a second closing tab, with a gap maintained between the first closing tab and the second closing tab.

[0010] Preferably, the outer surfaces of the two closed plate groups facing away from each other are provided with a plurality of guide grooves.

[0011] Preferably, the end of the rubber tube away from the mounting cap is fixed with two sets of magnetic sheets that can attract each other.

[0012] Preferably, the opposing surfaces of the two magnetic sheet groups are both roughened.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) When the water outlet drains, the end of the rubber tube away from the installation cap is subjected to water pressure and undergoes elastic deformation, thus opening the tube and allowing water to flow smoothly into the kettle. When the water outlet does not drain, the end of the rubber tube away from the installation cap is closed and is long and flat. The water droplets inside the rubber tube are sealed inside the rubber tube, and the water remaining at the tube opening is evenly attached to the surface of the long and flat tube opening, making it difficult for water droplets to accumulate and fall. This prevents water droplets from falling onto the surface of the tea bar machine after the kettle is removed, thus avoiding contamination.

[0015] (2) The rubber tube ends are in a closed state, which can also prevent the inside of the rubber tube from being in contact with air for a long time, thus avoiding internal pollution and causing the discharged drinking water to be contaminated.

[0016] (3) In one of the schemes, the edge of the closed plate group is blade-shaped, which can reduce the contact area between water droplets and the closed plate group, reduce excessive water contact with the closed plate group, thereby avoiding the formation of liquid on the surface of the closed plate group, which would cause dripping and contamination of the tea bar machine surface.

[0017] (4) In one of the schemes, the magnetic sheet group can make the end of the rubber tube more tightly closed, preventing the water remaining in the rubber tube from flowing out. The magnetic sheet group is rough on the opposite side, which can disperse the water at the end of the magnetic sheet group through capillary action, preventing it from forming droplets.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0028] Example 1:

[0029] like Figures 1-2 As shown, the tea bar machine includes a main body 1 and a back panel 2. A drip-proof water outlet structure is installed on the back panel 2, including a water outlet. The water outlet is a tubular outlet for discharging drinking water. It is located on the main body 1 of the tea bar machine and is used to transport drinking water to an external container. As the starting point of the water flow, the water outlet allows the water to flow smoothly when it is discharging, but water droplets may remain when the water stops discharging, causing potential pollution.

[0030] A water outlet head 3 is installed on the water outlet. The water outlet head 3 is a device used to prevent water droplets from falling after the water is stopped. It is fixed to the end of the water outlet through a connecting part, thereby forming a drip-proof barrier between the water outlet and the external environment. The installation of the water outlet head 3 effectively reduces the possibility of water droplets falling and avoids water contamination of the tea bar machine surface after the kettle is removed.

[0031] The water outlet head 3 includes a mounting cap 31, which is a base component of the water outlet head 3. It is directly connected to the end of the water outlet, and is detachably fixed by means of a threaded connection to ensure a sealed connection between the two. The threaded connection facilitates installation and maintenance, while providing stable mechanical support.

[0032] A rubber tube 32 is connected to the end of the mounting cap 31 away from the water outlet. The rubber tube 32 is made of elastically deformable silicone or similar material, and its proximal end is firmly sleeved or fused to the outlet of the mounting cap 31 to form a continuous flow channel. The end of the rubber tube 32 away from the mounting cap 31 is processed into a duckbill shape. The duckbill-shaped end is a flat and narrow structure. Its end closes naturally when there is no external force, forming a seal. As the distal extension of the rubber tube 32, it opens under the pressure of water flow to allow water to flow out when water is discharged, and closes when water discharge stops. The flat tube opening design allows residual water to adhere evenly to the surface, making it less likely to accumulate into water droplets, thereby avoiding dripping and contamination.

[0033] At the duckbill-shaped end of the rubber tube 32 away from the mounting cap 31, its surface is roughened. The roughened surface is a fine texture or coating processed on the outside of the tube opening, which is integrated with the duckbill-shaped end. This roughening increases the surface adhesion of water, further reduces the risk of water droplet formation and dripping, and can disperse water, promote water evaporation, and prevent water from adhering to the surface of the rubber tube 32 for a long time, which would lead to the growth of bacteria on the outer surface of the rubber tube 32.

[0034] Example 2:

[0035] Unlike Example 1, as Figure 3 Two rigid closure plate assemblies are fixed at the end of the rubber tube 32 away from the mounting cap 31. Each closure plate assembly includes a first closure plate 41 and a second closure plate 42, with a gap between them. When water flows out, the end of the rubber tube 32 opens, and the closure plate assemblies can be bent through the gap between the first and second closure plates 41 and 42, facilitating water flow. The closure plate assemblies are made of plastic or metal and are symmetrically fixed to the two edges of the duckbill-shaped end, fitting together. The closure plate assemblies enhance the closure effect, fitting tightly in their natural state, improving sealing and preventing micro-leakage.

[0036] The ends of the two closed tabs away from the rubber tube 32 are processed into a blade shape. The blade-shaped edges are the thin, sharp portions at the ends of the closed tabs, which are achieved through cutting or molding processes. This structure forms a tighter line contact seal when closed, enhancing the anti-drip capability.

[0037] Several flow guide grooves are formed on the outer surfaces of the two closed plate groups facing away from each other. The flow guide grooves are small grooves distributed longitudinally or laterally along the surface of the closed plate groups. The flow guide grooves are integrally formed with the outer surface of the closed plate groups. The flow guide grooves can guide water to disperse and prevent it from concentrating into droplets. At the same time, they can also promote the rapid evaporation of water and prevent bacteria from growing on the surface of the flow guide grooves for a long time.

[0038] Example 3:

[0039] Unlike Example 1, as Figure 4 As shown, two magnetic sheet assemblies are fixed at the end of the rubber tube 32 away from the mounting cap 31. These magnetic sheet assemblies are made of permanent magnet material and are embedded or fixed to the duckbill-shaped structure. They are connected to the end of the rubber tube 32, and the magnetic attraction enhances the sealing effect of the closure assembly when there is no water flow, further improving the anti-drip performance. The magnetic sheet assembly includes a first magnetic sheet 51 and a second magnetic sheet 52, with a gap between them. When water flows out, the end of the rubber tube 32 opens, and the magnetic sheet assembly can be bent through the gap between the first magnetic sheet 51 and the second magnetic sheet 52, facilitating water flow.

[0040] The opposing surfaces of the two magnetic sheet groups are both roughened. The roughened opposing surfaces are textured surfaces processed in the contact area of ​​the magnetic sheet groups (this feature is not shown in the figure because it is a microscopic feature). This structure is integrated with the magnetic sheet groups, which increases the interfacial friction and prevents the water film from breaking and dripping. At the same time, the roughened opposing surfaces of the magnetic sheet groups can disperse the water at the ends of the magnetic sheet groups through capillary action, preventing it from forming droplets and falling.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
