Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a fresh-keeping reverse osmosis water dispenser. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, bottled water dispensers have become common drinking water equipment in homes and offices due to their convenience and relatively safe water quality. Common bottled water dispensers use a smart seat structure on top to support an inverted water tank. A pin inside the smart seat punctures the water tank lid, guiding the water flow into the water tank or heating and cooling system inside the machine. However, in actual use, this traditional open interface design has gradually exposed hidden dangers that affect water quality safety.

[0003] Traditional water dispensers often leave the inlet completely open after the water tank is removed, and the connection between the smart base and the neck of the water tank relies solely on simple gravity contact, lacking effective sealing measures. This structure allows dust, bacteria, insects, and other contaminants from the air to easily fall directly into the water storage space inside the machine through the open inlet when the water tank is being replaced or when the water dispenser is not in use. This leads to bacterial growth inside the water dispenser and causes serious secondary pollution. This not only reduces the freshness and safety of drinking water but also increases the burden of frequent cleaning and maintenance for users, making it difficult to meet the modern consumer's demand for high-quality and healthy drinking water.

[0004] Therefore, this utility model proposes a reverse osmosis water dispenser to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems in the existing technology, such as the lack of an effective automatic sealing structure at the water inlet of the water dispenser when the water tank is replaced or when it is not in use, which makes it easy for dust and bacteria to enter, and the poor sealing at the interface between the water tank and the machine, which causes pollutants to seep in, this utility model aims to provide a fresh-keeping reverse osmosis water dispenser with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a reverse osmosis water dispenser for preservation, including a shell and an opening and closing mechanism fixedly connected to the top wall of the shell. The opening and closing mechanism includes a temporary water box fixedly connected to the top wall of the shell, and a water pipe that passes through and is fixed to the middle of the bottom wall of the temporary water box. A top cone is fixedly connected to the top of the water pipe, and a sealing ring is slidably connected to the upper part of the outer wall of the water pipe. A spring is sleeved on the bottom of the outer wall of the water pipe, and water inlets are opened on the left and right side walls of the water pipe. When the spring is in its naturally extended state, the water inlets are blocked by the inner wall of the sealing ring. The bottom end of the spring abuts against the bottom wall of the temporary water box, and the top end of the spring abuts against the bottom wall of the sealing ring. The sealing ring is used to slide down along the water pipe and compress the spring to expose the water inlets when subjected to external pressure.

[0007] Preferably, the bottom wall of the temporary water box has multiple water inlet holes equidistantly spaced along the circumference, and a bracket is provided at the bottom of the water inlet hole. The bracket is fixedly connected to the bottom wall of the temporary water box. The design of multiple water inlet holes can assist the main water channel to quickly guide the flow and balance the internal and external air pressure, ensuring smooth water output.

[0008] Preferably, a sealing cap is slidably connected to the inner wall of the water inlet, and a second spring is fixedly connected to the top of the bracket. The top of the second spring abuts against the bottom wall of the sealing cap. Through the cooperation of the sealing cap and the second spring, the auxiliary water circuit can be automatically reset and sealed in the absence of a tank.

[0009] Preferably, a second water inlet is provided in the upper middle part of the outer wall of the sealing cover. When the second spring is in a naturally extended state, the bottom wall of the sealing cover closes the water inlet. When the sealing cover is pressed down, the second water inlet connects with the water inlet, thereby opening the auxiliary water passage.

[0010] Preferably, a sealing mechanism is provided around the top of the outer casing. The sealing mechanism includes a mounting cover fixedly connected to the top of the outer casing. The mounting cover is used to cover the neck of the inserted water storage tank and provide a basic sealed environment for the external interface.

[0011] Preferably, the inner wall of the mounting cover is fixedly connected with sealing strip one, sealing strip two and sealing strip three from top to bottom. The multi-layer sealing strip design can fill the gap between the water storage tank and the mounting cover through multi-level interference fit, thereby enhancing the physical isolation effect.

[0012] Preferably, the top wall of the mounting cover is fixedly connected to a mounting groove, and a rubber airbag is fixedly connected inside the mounting groove. As an active sealing element, the rubber airbag can adapt to the surface of water storage tanks of different shapes after inflation, eliminating the minute gaps that will be generated by rigid fit.

[0013] Preferably, the right side of the rubber airbag is connected to an air nozzle, which is used to inflate the rubber airbag in the mounting groove with gas, so that the user can adjust the expansion degree of the airbag according to the actual sealing requirements to ensure the best sealing and isolation state.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing water dispensers having an open water inlet during water tank replacement, which is prone to contamination by external dust and bacteria entering the machine. The water inlet is automatically opened and closed by a spring-driven automatic opening and closing mechanism installed in the water inlet channel. The water tank's own weight overcomes the elastic force to drive the sealing ring and sealing cover to slide down to connect the water path. When the water tank is pulled out, the spring's restoring force drives the sealing component to automatically reset and seal the water inlet. This achieves the effect of automatically isolating the external environment during water replacement or when the machine is empty, effectively preventing secondary pollution and keeping the water inside the machine fresh.

[0015] 2. This utility model solves the problem in the prior art where uneven surfaces or slight differences in size of the water tank cause poor sealing at the interface and easy gaps. It utilizes the multiple layers of physical barriers combined with the flexible fit of the inflated airbag to cover the neck of the water tank. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example:

[0019] Please refer to Figures 1 to 6This utility model provides a reverse osmosis water dispenser for preservation, which aims to solve the structural defects in the prior art where the water inlet is open during the replacement of the water storage tank, leading to the intrusion of external dust and bacteria, and the poor sealing at the interface between the water storage tank and the water dispenser, resulting in the infiltration of contaminants.

[0020] Please refer to Figure 1 and Figure 2 A reverse osmosis water dispenser for freshness preservation includes a shell 1 and an opening and closing mechanism 2 fixedly connected to the top wall of the shell 1. The shell 1 serves as the supporting frame of the overall device and provides an internal water storage space. The opening and closing mechanism 2 is located at the bottom interface of the water storage tank to control the automatic opening and closing of the water circuit. The opening and closing mechanism 2 includes a temporary water box 201 fixedly connected to the top wall of the shell 1 and a water pipe 202 that penetrates and is fixed in the middle of the bottom wall of the temporary water box 201. The temporary water box 201 is used to initially receive and guide the water before it flows into the interior of the shell 1. The water pipe 202 serves as the main water inlet channel to guide the water flow into the interior of the shell 1.

[0021] Please refer to Figure 2 , Figure 3 and Figure 4 A top cone 204 is fixedly connected to the top of the water pipe 202. The top cone 204 is used to pierce the top cover of the water storage tank when it is installed. A sealing ring 205 is slidably connected to the upper middle part of the outer wall of the water pipe 202. The sealing ring 205 is used to cover and seal the outer wall when there is no water storage tank. A spring 206 is sleeved on the bottom of the outer wall of the water pipe 202. The spring 206 is used to provide elastic potential energy to drive the sealing ring 205 to return to its original position. The bottom end of the spring 206 abuts against the bottom wall of the temporary water box 201. The top of the spring 206 abuts against the bottom wall of the sealing ring 205. The left and right side walls of the water pipe 202 are provided with water inlets 203. When the spring 206 is in a naturally extended state, the water inlets 203 are blocked and covered by the inner wall of the sealing ring 205. When the sealing ring 205 is pressed down by the weight of the water storage tank, it slides down along the water pipe 202 and compresses the spring 206, thereby exposing the water inlets 203. The water inlets 203 are used to allow water in the water storage tank to flow through and enter the interior of the water pipe 202.

[0022] Please refer to Figure 2 and Figure 4 The bottom wall of the temporary water box 201 is provided with multiple water inlet holes 210 at equal intervals along the circumference. The water inlet holes 210 are used as auxiliary channels to guide water flow into the interior of the outer shell 1 and to help balance the air pressure inside and outside the water storage tank. A bracket 209 is provided at the bottom of the water inlet hole 210. The bracket 209 is fixedly connected to the bottom wall of the temporary water box 201. The bracket 209 is used to provide a stable support base for the internal elastic components. A spring 208 is fixedly connected to the top of the bracket 209. The spring 208 is used to provide an upward restoring force.

[0023] Meanwhile, a sealing cap 207 is slidably connected to the inner wall of the water inlet 210. The sealing cap 207 is used to block or open the water inlet 210. The top of the second spring 208 abuts against the bottom wall of the sealing cap 207. A second water inlet 211 is provided in the upper middle part of the outer wall of the sealing cap 207. When the second spring 208 is in a naturally extended state, the second water inlet 211 is blocked by the inner wall of the water inlet 210. At this time, the bottom wall of the sealing cap 207 closes the water inlet 210 under the elastic force of the second spring 208. When the sealing cap 207 is pressed down by the edge of the neck of the water tank, it slides down along the water inlet 210 and compresses the second spring 208. The second water inlet 211 moves down with the sealing cap 207 and is exposed below the water inlet 210, thereby connecting the water inlet 210 with the outside and forming an auxiliary water flow channel. This dual water path design ensures that the water tank can quickly dispense water and maintain a stable water supply at the moment of insertion.

[0024] As a preferred embodiment, to prevent external impurities from entering through the gap between the water storage tank and the water dispenser, please refer to... Figure 5 and Figure 6 A sealing mechanism 3 is provided around the top of the outer shell 1. The sealing mechanism 3 is used to provide multiple seals for the neck of the water storage tank. The sealing mechanism 3 includes a mounting cover 301 fixedly connected to the top of the outer shell 1. The mounting cover 301 is located above the opening and closing mechanism 2. The inner wall of the mounting cover 301 is fixedly connected from top to bottom with a sealing strip 302, a sealing strip 303, and a sealing strip 304. The sealing strips 302, 303, and 304 are all made of annular rubber and are arranged circumferentially along the inner wall of the mounting cover 301. The sealing strips 302, 303, and 304 are used to fill the gap between the mounting cover 301 and the neck of the water storage tank through multiple interference fits.

[0025] As another preferred embodiment, in order to accommodate the slight deformation of different water storage tank surfaces and ensure absolute reliability of the seal, please refer to... Figure 5 The top wall of the mounting cover 301 is fixedly connected to a mounting groove 305, which is an annular groove structure. A rubber air bladder 307 is fixedly connected inside the mounting groove 305. The rubber air bladder 307 is used to flexibly abut against the outer wall of the water storage tank after inflation. An air nozzle 306 is connected to the right side of the rubber air bladder 307. One end of the air nozzle 306 is connected to the inside of the rubber air bladder 307, and the other end of the air nozzle 306 extends through the side wall of the mounting cover 301 to the outside of the mounting cover 301. The air nozzle 306 is used to connect an external inflation device to inflate the rubber air bladder 307 in the mounting groove 305 with gas.

[0026] Working principle: When the top of the water storage tank is inserted upside down into the top of the outer shell 1, since the opening and closing mechanism 2 is located at the bottom interface of the water storage tank, the top cone 204 first pierces the top cover of the water storage tank. Then the water storage tank continues to descend under its own gravity. At this time, the flat surface of the top of the water storage tank will press against the top of the sealing ring 205 and the top of the sealing cover 207. As the water tank continues to be pressed downwards, the sealing ring 205 slides downwards along the outer wall of the water pipe 202 under force, compressing the spring 206. The previously obscured inlet 203 gradually becomes visible. At the same time, the neck edge of the water tank presses down on the sealing cap 207, causing it to slide downwards along the inlet 210 and compress the spring 208. This causes the bottom wall of the sealing cap 207 to leave the inlet 210, and the inlet 211 to move below the inlet 210. At this point, both inlets 203 and 211 open simultaneously. Water in the storage tank enters the water pipe 202 through inlet 203 and is guided by inlet 210 and inlet 211 to flow quickly into the outer shell 1. During this process, the neck of the storage tank is inserted into the mounting cover 301, which sequentially squeezes the sealing strip 302, sealing strip 303 and sealing strip 304 to achieve multi-layer physical sealing. The rubber air bladder 307 is inflated through the air nozzle 306, so that the inflated rubber air bladder 307 fits tightly against the outer wall of the storage tank, further isolating external air and pollutants. When the water tank needs to be replaced and is pulled out, the downward pressure applied to the sealing ring 205 and the sealing cover 207 disappears. Under the restoring force of the spring 206, the sealing ring 205 slides upward along the water pipe 202 to reset, re-blocking and sealing the water inlet 203. At the same time, under the restoring force of the spring 208, the sealing cover 207 slides upward along the water inlet 210 to reset, and the bottom wall of the sealing cover 207 re-seals the water inlet 210. At this time, both the main water circuit and the auxiliary water circuit are automatically cut off and sealed, preventing external dust and bacteria from entering the interior of the outer casing 1 through the open interface when the tank is not in use, thereby effectively maintaining the cleanliness of the internal environment of the water dispenser and the freshness of the water quality.
