Description

Technical Field

[0001] The utility model relates to the technical field of drainage structures, in particular to a one-way drainage valve and an ice storage bucket. Background Art

[0002] An ice bucket is a tool for storing ice cubes, mainly used to keep drinks or food cool. This device is usually made of plastic, metal or other low-temperature resistant materials so that it can withstand low temperatures and prevent ice from melting. Ice buckets are widely used. For example, in commercial scenarios such as milk tea shops, coffee shops, dessert shops or restaurants, people can use ice buckets to store ice cubes to keep drinks cool.

[0003] When storing ice cubes in an ice bucket, the ice cubes usually melt gradually, and the water produced by the melting will flow to the bottom of the ice bucket due to gravity. Most of the ice buckets sold on the market have various drain ports, but the drain ports of existing ice buckets can only be used for drainage, and there is no perfect structure to prevent the backflow of ice water or the backflow of odor. If there is a drainage structure with such an anti-backflow structure, it is too tight and needs to be opened manually to drain. It cannot have the functions of automatic drainage and anti-backflow and anti-odor at the same time, which is inconvenient for daily use.

[0004] In view of the above shortcomings, we need to develop a one-way drain valve and ice storage bucket to meet the needs of the majority of users. Utility Model Content

[0005] In view of the above-mentioned problem that the existing ice storage bucket drainage structure has no convenient structure to prevent ice water from flowing back or odor from being transmitted back, and is inconvenient for daily use, the technical solution adopted by the utility model to solve the technical problem is:

[0006] A one-way drainage valve comprises a valve body, wherein the valve body is provided with a hollow water passage cavity, wherein the water passage cavity is provided with a water inlet and a water outlet communicating with the outside, wherein the water inlet is provided with a water inlet sealing cap for filtering debris, and the water outlet is hinged with a water outlet sealing cap for one-way drainage, and the water outlet sealing cap can rotate relative to the valve body;

[0007] The water outlet sealing cover forms an inclined angle with a horizontal plane, and the water outlet sealing cover is provided with a hinge part for hingedly connecting the valve body.

[0008] Furthermore, in some embodiments, the water passage chamber is provided with a water launching platform for centrally guiding the water flow, and the water launching platform is provided with a water launching port connected to the water outlet.

[0009] Furthermore, in some embodiments, a guide portion is provided between the water outlet and the water down port, and the guide portion is provided with a guide curved surface for guiding the flow of liquid, and the guide curved surface is used to guide the water flow to flow in the direction of the water outlet cover.

[0010] Furthermore, in some embodiments, a counterweight boss is provided on one side of the water outlet cover away from the hinge portion to facilitate the water outlet cover to close the water outlet, the angle range of the angle is 10-80 degrees, and the water outlet cover moves within the angle space.

[0011] Furthermore, in some embodiments, the water inlet cover is provided with a first finger hole and a second finger hole for facilitating manual disassembly and assembly, and the aperture of the first finger hole is not equal to the aperture of the second finger hole.

[0012] Furthermore, in some embodiments, a plurality of support columns for strengthening the load-bearing capacity are extended from the water inlet cover toward one side of the water launching platform, and the support columns are arranged in a circle around the outer side of the water launching port.

[0013] Furthermore, in some embodiments, a valve port step for installing the water inlet sealing cover is provided at the connection between the water passage cavity and the water inlet, and a sealing step cooperating with the valve port step is provided on the side of the water inlet sealing cover facing the flow guide portion.

[0014] Further, in some embodiments, an ice storage bucket includes a bucket body and the one-way drain valve installed on the bucket body, and the one-way drain valve is detachably connected to the bottom of the bucket body.

[0015] Furthermore, in some embodiments, a fan-shaped guide groove is provided at the bottom of the barrel body, and a drainage channel connected to the outside is opened in the guide groove, and the one-way drainage valve is detachably installed at the entrance of the drainage channel.

[0016] Furthermore, in some embodiments, edge platforms are provided on the top of four sides of the barrel body for easy installation and snap-fitting, and the surface of the edge platform forms an inclination angle with the horizontal plane and tilts inward.

[0017] The beneficial effects of the utility model are as follows:

[0018] 1. The drainage structure of the utility model is provided with a water outlet sealing cover which can be automatically closed by natural gravity on one side of the water outlet. The water outlet forms a certain inclined angle with the horizontal plane, so that the water flow can flush the water outlet sealing cover after entering the water cavity, and automatic drainage is realized without manually opening the drainage structure. After the ice water flows away, the water outlet sealing cover automatically closes the water outlet under the influence of natural gravity, thereby preventing the ice water from flowing back and isolating the external odor.

[0020] 3. The drainage structure of the utility model can also be applied to a special ice storage bucket. The ice storage bucket is provided with a guide groove for guiding ice water.

[0032] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 6 As shown, a one-way drainage valve comprises a valve body 1, wherein the valve body 1 is provided with a hollow water passage cavity 11, wherein the water passage cavity 11 is provided with a water inlet 12 and a water outlet 13 communicating with the outside, wherein the water inlet 12 is provided with a water inlet sealing cover 2 for filtering debris, and the water outlet 13 is hinged with a water outlet sealing cover 3 for one-way drainage, and the water outlet sealing cover 3 can rotate relative to the valve body 1;

[0034] The water outlet sealing cover 3 forms an inclined angle 131 with a horizontal plane, and the water outlet sealing cover 3 is provided with a hinge portion 31 for hingedly connecting the valve body 1 .

[0035] Specifically, in some embodiments, the valve body 1 is the outer shell of the one-way drain valve. The valve body 1 adopts a thin-wall design and has a relatively light and thin shell as a whole. The water passage chamber 11 is a chamber of the valve body 1 for water to flow through. A water inlet 12 connected to the outside is provided on one side of the water passage chamber 11 close to the top of the valve body 1, and a water outlet 13 connected to the outside is provided on one side of the water passage chamber 11 close to the bottom of the valve body 1. The water inlet 12 is equipped with a water inlet cover 2 for filtering debris. A plurality of through filter slots 23 are provided on the water inlet cover 2. The filter slots 23 are in the shape of long strips with a long length and a narrow width, which can isolate some larger debris and avoid clogging the water outlet 13. The filter slots 23 are evenly spaced on the water inlet cover 2, and the water outlet 13 is hinged with a water outlet cover 3 for one-way drainage, and the water outlet cover 3 is in the shape of the water outlet 13. The rotating flip cover, the water outlet sealing cover 3 is hinged to the end of the water outlet 13 near the water inlet through the hinge part 31, and the water outlet sealing cover 3 forms an inclined angle 131 with the horizontal plane, and the angle 131 is an acute angle. The water outlet sealing cover 3 moves within the angle range of the angle 131, so that the water outlet sealing cover 3 can be hinged and fitted to the water outlet 13 by its own gravity in a normal state. When the ice water melts from the ice cube, it flows into the water cavity 11 through the side wall and flows to the water outlet 13. The flow inertia and the accumulated water flush the water outlet sealing cover 3, and the water flows out of the valve body 1. When the ice water flows out, the water outlet sealing cover 3 is re-fitted with the water outlet 13 by natural gravity, so that the external ice water cannot flow back to the water cavity 11, and the external odor cannot be transmitted back to the water cavity 11, thereby ensuring that the interior of the water cavity 11 is protected from external pollution, and further protecting the internal hygiene of the ice storage bucket.

[0036] like Figure 3 and Figure 6 As shown, the water passage chamber 11 is provided with a water discharge platform 111 for centrally guiding the water flow, and the water discharge platform 111 is provided with a water discharge port 112 connected to the water outlet 13 .

[0037] Specifically, in some embodiments, a water discharge platform 111 is provided in the middle of the water passage chamber 11 for centrally guiding the water flow. The water discharge platform 111 is horizontally arranged at the lower side of the water inlet cover 2. A water discharge port 112 connected to the water outlet 13 is provided in the middle of the water discharge platform 111. A circular arc angle is provided at the connection between the water discharge port 112 and the water discharge platform 111 for guiding the flow of ice water. The water discharge platform 111 can be tilted toward the water discharge port 112 in the middle, which is more convenient for diverting water to the water discharge port 112. The water discharge port 112 is provided at the lower side of the water inlet cover 2. A water-passing platform 113 is also provided between the water outlet 13 and the water outlet 13. When ice water melts from ice cubes, it flows into the water-passing cavity 11 through the side wall. The ice water converges from the water-dropping platform 111 toward the water-dropping port 112. A part of the ice water flows directly to the water outlet 13, and the other part falls into the water-passing platform 113 and then flows into the water outlet 13. The hinge position of the water outlet sealing cover 3 can be adjusted by adjusting the area of ​​the water-passing platform 113. The overall structure is simple, easy to produce, and has a good diversion effect, achieving the effects of accelerating water drainage and concentrated water drainage.

[0038] like Figures 1 to 4 as well as Figure 6 and Figure 7 As shown, a guide portion 14 is provided between the water outlet 112 and the water outlet 13 , and the guide portion 14 is provided with a guide curved surface 141 for guiding the flow of liquid, and the guide curved surface 141 is used to guide the water flow to flow in the direction of the water outlet sealing cover 3 .

[0039] Specifically, in some embodiments, the guide portion 14 is a cavity structure of the drain valve used to guide the ice water to another water flow direction. The guide portion 14 is hemispherical and is arranged outward between the drain port 112 and the water outlet hole 13 and protrudes in the direction away from the drain port 112. The guide portion 14 is arranged in the obtuse angle space formed by the water outlet cover 3 and the horizontal plane outside the angle 131. The guide portion 14 is provided with a spherical guide curved surface 141. After the ice water flows into the drain port 112 from the water launch platform 111, the guide portion 14 further gathers the volume of the ice water through the guide curved surface 141, so that the ice water changes from the original scattered form to the gathered form, thereby strengthening the flow impact force of the ice water. The gathered water flow slides and accelerates through the spherical guide curved surface 141, and flushes the water outlet cover 3 in one fell swoop, thereby reducing the amount of water required to flush the water outlet cover 3, and reducing the required hydraulic force to flush the water outlet cover 3, making the drainage process more convenient.

[0040] like Figure 6 As shown, a counterweight boss 32 is provided on one side of the water outlet sealing cover 3 away from the hinged portion 31 to facilitate the water outlet sealing cover 3 to close the water outlet 13. The angle range of the angle 131 is 10-80 degrees, and the water outlet sealing cover 3 moves within the space of the angle 131.

[0041] Specifically, in some embodiments, the water outlet sealing cover 3 is further provided with a counterweight boss 32 for enhancing the gravity falling effect. The counterweight boss 32 extends and protrudes toward the side of the water outlet sealing cover 3 away from the water outlet 13, thereby increasing the volume of the water outlet sealing cover 3 and the fitting force between the water outlet sealing cover 3 and the water outlet 13, thereby forming a sealing effect to prevent backflow and odor. The angle 131 is the rotation space of the water outlet sealing cover 3 after being flushed open by water. The angle range of the angle 131 determines the amount of water required for the water flow to flush open the water outlet sealing cover 3. The larger the angle of the angle 131, the more likely it is that the water outlet sealing cover 3 will be flushed open. The smaller the required amount of water, the smaller the required impact force, but the worse the sealing effect of the water outlet cover 3. The smaller the angle 131, the more water is required to break open the water outlet cover 3, the greater the required impact force, but the better the sealing effect of the water outlet cover 3. When designing the angle 131, it is necessary to weigh the balance between the ice water flow rate and the sealing effect. The angle range of the angle 131 can be controlled within 10-80 degrees. Preferably, when the angle 131 is set to 67.5 degrees, the required ice water flow rate and the sealing effect can achieve a relatively ideal effect.

[0042] Specifically, in some embodiments, one of the counterweight boss 32 and the water outlet 13 can be installed with a magnet, and the other of the counterweight boss 32 and the water outlet 13 can be installed with a magnetic metal accessory, so that when the counterweight boss 32 is close to the water outlet 13, the magnetic adsorption principle can be used to enhance the sealing between the counterweight boss 32 and the water outlet 13, so that the external ice water cannot flow back to the water chamber 11, and the external odor cannot be transmitted back to the water chamber 11, thereby ensuring that the interior of the water chamber 11 is protected from external pollution, and further protecting the internal hygiene of the ice storage bucket.

[0043] Specifically, in some embodiments, the counterweight boss 32 is arranged in a U-shaped strip on the side of the water outlet sealing cover 3 away from the hinge part 31, and the U-shaped structure of the counterweight boss 32 protrudes in the direction away from the hinge part 31, further enhancing the counterweight effect and enhancing the sealing effect of the water outlet sealing cover 3 against the water outlet 13.

[0044] like Figures 3 to 5 as well as Figure 1 As shown, the water inlet sealing cover 2 is provided with a first finger hole 21 and a second finger hole 22 for easy manual disassembly and assembly, and the aperture of the first finger hole 21 is not equal to the aperture of the second finger hole 22 .

[0045] Specifically, in some embodiments, the first finger hole 21 and the second finger hole 22 are arranged on both sides of the water inlet cover 2, and the distance between the first finger hole 21 and the second finger hole 22 can be extended to a distance suitable for an adult to insert and clamp their fingers. The first finger hole 21 can be suitable for the thumb of the hand to insert, and the second finger hole 22 can be suitable for other fingers of the hand to insert. Since the diameter of the thumb is usually larger than that of other fingers, the aperture of the first finger hole 21 is larger than the aperture of the second finger hole 22. In addition, when the second finger hole 22 is used to insert the thumb, the aperture of the second finger hole 22 is larger than the aperture of the first finger hole 21. The design of the first finger hole 21 and the second finger hole 22 helps the user to easily disassemble and install the water inlet cover 2, and facilitates the adjustment of the installation gap when installing the water inlet cover 2, so that the water inlet cover 2 is installed more firmly.

[0046] like Figure 3 , Figure 4 and Figure 6 As shown, a plurality of support columns 24 for strengthening the load-bearing force extend from the water inlet cover 2 toward one side of the water discharge platform 111 , and the support columns 24 are arranged in a circle around the outer side of the water discharge port 112 .

[0047] Specifically, in some embodiments, the water inlet cover 2 is also squeezed by the natural gravity of a large number of ice cubes. When the ice cubes are piled up in the ice storage bucket and squeeze the drain valve, the ice cubes are large in size and will not pass through the water inlet cover 2 and slide into the water cavity 11. At this time, the water inlet cover 2 is the main force-bearing component. A plurality of support columns 24 for strengthening the load-bearing force are extended from the side of the water inlet cover 2 toward the water discharge platform 111, which can enhance the load-bearing and anti-deformation capacity of the water inlet cover 2 when the number of ice cubes is large. The support columns 24 surround the outer side of the discharge port 112 in a circular shape. The support columns 24 are arranged at intervals around the water surface, and the extended length of the support columns 24 can better contact the surface of the water launching platform 111 when the water inlet cover 2 is installed. The position where the support columns 24 contact the surface of the water launching platform 111 is a foothold for gravity dispersion. When the water inlet cover 2 bears weight, the gravity can be dispersed at each foothold through the support columns 24, so that the load-bearing force of the water inlet cover 2 is increased by utilizing the overall structure, and the deformation resistance of the water inlet cover 2 is improved, so as to avoid being squeezed and deformed by ice cubes, which makes it inconvenient to remove and maintain, and improve the durability of the drain valve.

[0048] like Figures 3 to 6 As shown, a valve port step 15 for installing the water inlet sealing cover 2 is provided at the connection between the water passage chamber 11 and the water inlet 12 , and a sealing step 25 cooperating with the valve port step 15 is provided on the side of the water inlet sealing cover 2 facing the flow guide portion 14 .

[0049] Specifically, in some embodiments, the valve mouth step 15 is arranged on the side of the water passage chamber 11 close to the water inlet 12, and the sealing step 25 is arranged on the side of the water inlet sealing cover 2 close to the guide portion 14. When installing the water inlet sealing cover 2, the sealing step 25 is aligned with the valve mouth step 15 and connected with a clearance fit, so that the water inlet sealing cover 2 can be smoothly installed. The valve mouth step 15 can also further limit the installation height and horizontal position of the water inlet sealing cover 2, further enhance the deformation resistance of the water inlet sealing cover 2, and utilize the overall structure to increase the load-bearing force of the water inlet sealing cover 2, thereby avoiding the inconvenience of removal and maintenance after being squeezed and deformed by ice cubes, thereby improving the durability of the drain valve.

[0050] like Figures 7 to 10 As shown, an ice storage bucket includes a bucket body 4 and a one-way drain valve installed on the bucket body 4, wherein the one-way drain valve is detachably connected to the bottom of the bucket body 4.

[0051] Specifically, in some embodiments, the above-mentioned drain valve is used in combination with an ice storage bucket. A drainage structure for use with the drain valve is provided at the bottom of the barrel body 4 of the ice storage bucket. The ice storage bucket can further enhance the hydrophobic drainage capacity after the ice cubes melt. A damping shaft 44 is also provided on the side wall of the barrel body 4 for easy lateral and longitudinal positioning, making the installation of the bucket cover more precise and convenient. The barrel body 4 has an outer shell made of sheet metal technology, and a limiting groove 45 is provided on the top of the barrel body 4. The limiting groove 45 is arranged along the top periphery of the barrel body 4, which further facilitates the precise installation of the bucket cover.

[0052] like Figures 7 to 9 As shown, a fan-shaped guide groove 41 is provided at the bottom of the barrel body 4 , and a drainage channel 42 communicating with the outside is opened in the guide groove 41 , and the one-way drainage valve is detachably installed at the entrance of the drainage channel 42 .

[0053] Specifically, in some embodiments, the guide groove 41 is a liquid gathering structure of the ice bucket used to strengthen the gathering of ice water at the bottom of the bucket body 4. The drainage channel 42 of the ice bucket is arranged on the side of the guide groove 41 close to the fan-shaped bottom. The drainage channel 42 is provided with an internal thread 421 for convenient connection to other drainage structures. The guide groove 41 is inclined toward one side of the fan-shaped bottom and is provided with a diversion angle, so that after the ice water melts and flows into the guide groove 41, it can flow to the drainage channel 42 along the diversion angle, thereby accelerating the flow of ice water and reducing the retention and accumulation of ice water.

[0054] like Figure 7 , Figure 8 and Fig.10 As shown, the top of the barrel body 4 is provided with an edge platform 43 for easy installation and buckling, and the surface of the edge platform 43 forms an inclination angle 431 with the horizontal plane and is inclined toward the inside.

[0055] Specifically, in some embodiments, the edge platform 43 is a corner structure for installing and snapping the barrel cover. The surface of the edge platform 43 forms an inclination angle 431 with the horizontal plane and inclines inward, so that when the condensed water on the barrel cover flows to the edge platform 43, it can flow along the inclination angle 431 toward the inside of the barrel body 4 to avoid flowing to the outside of the barrel body 4 and polluting the external environment. The limiting groove 45 is arranged on the surface of the edge platform 43, and the edge platform 43 is arranged along the top periphery of the barrel body 4, which further facilitates the precise installation of the barrel cover and the collection of condensed water.

[0056] like Figures 1 to 6 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0057] When ice water melts from ice cubes, it flows into the water chamber 11 through the side wall of the valve body 1 and flows through the water discharge platform 111. The water discharge platform 111 gathers the ice water at the discharge port 112. The ice water flows into the guide portion 14 from the discharge port 112 and flows to the water outlet 13 along the guide curved surface 141. The flow inertia and the accumulated water volume break the water outlet cover 3, and the ice water flows out of the valve body 1. The drainage function can be completed without manually opening the drain valve, thereby realizing the automatic discharge of the ice water.

[0058] When most of the ice water has flowed out, the remaining ice water is insufficient to push open the water outlet cover 3. The water outlet cover 3 is reattached to the water outlet 13 due to the natural gravity and the gravity reinforcement effect of the counterweight boss 32, so that the external ice water cannot flow back to the water passage chamber 11, and the external odor cannot be transmitted back to the water passage chamber 11, thereby ensuring that the interior of the water passage chamber 11 is protected from external pollution, achieving the effect of preventing the ice water from flowing back and preventing the odor from being transmitted back.

[0059] When the water cavity 11 needs to be cleaned, the user can insert fingers into the first finger hole 21 and the second finger hole 22 respectively, and easily lift the water inlet cover 2 to clean the space of the water cavity 11. After cleaning, the water inlet cover 2 can be put back to complete the steps of disassembling and installing the water inlet cover 2.

[0060] When the drain valve needs to be maintained, the user can insert his fingers into the first finger hole 21 and the second finger hole 22 respectively, easily lift the water inlet cover 2, then insert his fingers into the guide part 14 and push open the water outlet cover 3, and use his fingers to hook out the entire drain valve with a little force. The drain valve can be replaced or cleaned, and the new drain valve can be directly installed into the installation position with one side of the water outlet 13 facing the installation position, so as to realize the quick disassembly and installation of the drain valve.

[0061] like Figures 1 to 6 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0062] Different from Example 1, in this embodiment, one of the counterweight boss 32 and the water outlet 13 is installed with a magnet, and the other of the counterweight boss 32 and the water outlet 13 is installed with a magnetic metal accessory, so that when the counterweight boss 32 is close to the water outlet 13, the magnetic adsorption principle can be used to enhance the sealing between the counterweight boss 32 and the water outlet 13, and the amount of water required for ice water to flush open the water outlet cover 3 can be controlled by adjusting the magnetic force.

[0063] like Figures 1 to 10 As shown, the specific implementation of Example 3 of the utility model is as follows:

[0064] Different from the first and second embodiments, the present embodiment further comprises an ice storage bucket. When the ice storage bucket is installed with the drain valve, the drain valve is directly installed into the drain channel 42 with the side of the drain valve close to the water outlet 13 facing the installation position, and the installation of the drain valve can be completed.

[0065] When the ice in the ice storage bucket melts, the ice water gathers and flows into the guide groove 41, and then flows to the drainage channel 42 along the guide angle. The ice water flows from the drainage channel 42 into the water inlet cover 2 of the drainage valve and enters the water passage chamber 11. The water discharge platform 111 gathers the ice water at the drain port 112. The ice water flows from the drain port 112 into the guide part 14 and flows to the water outlet 13 along the guide curved surface 141. The flow inertia and the accumulated water flush the water outlet cover 3, and the ice water flows out of the barrel body 4 through the drainage channel 42. The drainage function can be completed without manually opening the drain valve, thereby realizing the automatic discharge of the ice water.

[0066] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
