Description

Technical Field

[0001] The utility model relates to the field of drinking water equipment, in particular to a drinking water machine which can be installed reliably. Background Art

[0002] At present, there are water tank leaks or dripping water from the water outlet of water dispensers on the market when the water tank is installed. For example, there is a water dispenser with a water outlet interface at the bottom of the water tank, a valve core that can move up and down is provided in the water outlet interface, and a water inlet interface is provided in the water inlet interface. During the installation of the water tank, the water inlet pipe can push the valve core. If the water inlet pipe pushes up the valve core first and the water outlet interface and the water inlet interface have not yet formed a seal, the water tank will leak; on the contrary, if the water outlet interface and the water inlet interface form a seal first, the air in the compressed pipeline will cause the water outlet to drip during the installation process, which is not conducive to improving the user experience. Utility Model Content

[0003] In order to solve the technical problems of water tank leakage or water nozzle dripping during water tank installation in the prior art, the utility model provides a water dispenser with reliable installation. By optimizing the sizes of the trigger rib, the push rod and the water tank protrusion, the trigger rib abuts the push rod while the water tank protrusion and the connector just form a seal, thereby solving the above-mentioned problems of water tank leakage or water nozzle dripping.

[0004] The utility model discloses a reliably installed water dispenser, comprising a body and a water tank detachably mounted on the body, the body being provided with a connector, the connector having a receiving groove, the receiving groove being provided with an opening at the top and a water outlet at the bottom, a first sealing ring being provided at the opening, a trigger rib extending upwardly being provided in the receiving groove, the water tank being provided with a water outlet and an annular protrusion extending downwardly from the bottom of the water outlet, the water outlet and the protrusion being connected to form a water outlet channel, an axially movable push rod being provided in the water outlet channel, a second sealing ring being sleeved on the upper end of the push rod, the trigger rib having a first position abutting against the bottom surface of the push rod and a second position detached from the push rod, in the first position, the protrusion being inserted into the opening and the outer wall of the protrusion being fitted against the inner wall of the first sealing ring, and in the second position, the second sealing ring blocking the water outlet.

[0005] The water dispenser of the utility model, which is reliably installed, also has the following additional technical features:

[0006] A filter screen is also provided in the containing tank. The filter screen is provided with a plurality of mesh holes. There is a gap between the mesh holes and the bottom wall of the containing tank.

[0007] The trigger rib extends upward from the upper surface of the filter screen and is integrally formed with the filter screen.

[0008] The trigger ribs include four prisms distributed in a cross shape, and the distribution range of the mesh extends to the space between two adjacent prisms.

[0009] The bottom wall of the receiving groove is provided with a convex rib protruding upward to lift the filter screen; or a bracket is provided at the bottom of the filter screen to isolate the mesh from the bottom wall of the receiving groove.

[0010] The top of the accommodating groove is provided with an annular rim forming the opening, and the lower surface of the first sealing ring is provided with an annular groove, and the rim is inserted into the groove; and / or the inner circumferential wall of the first sealing ring is inclined toward the center of the accommodating groove to form a closed end; and / or the inner wall of the first sealing ring is provided with a sealing rib abutting against the protrusion.

[0011] A reset piece is sleeved on the outer side of the push rod. When the water tank is installed in place, the reset piece is in an elastic deformation state.

[0015] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The utility model has a reliable installation of the water dispenser. During the installation of the water tank, it can ensure that the water tank protrusion and the connector form a seal while the trigger rib abuts against the push rod. This can avoid the problem of water tank installation leakage when the trigger rib first pushes up the push rod while the water tank protrusion and the connector are not yet sealed. It can also avoid the problem of dripping from the water outlet of the water dispenser when the water tank protrusion and the connector are sealed first and the trigger rib pushes up the push rod later. Therefore, the reliability of the water tank installation is improved, and the user experience can be enhanced.

[0017] 2. As a preferred embodiment, a filter screen is further provided in the receiving tank, and a plurality of mesh holes are formed on the filter screen, and a gap is provided between the mesh holes and the bottom wall of the receiving tank; thereby, the water in the water tank can be filtered through the filter screen after flowing into the receiving tank, thereby improving the quality of the water finally flowing out of the connector and ensuring the health of the user; since there is a gap between the mesh holes and the bottom wall of the receiving tank, the mesh holes will not be tightly attached to the bottom wall of the receiving tank, so that the water can flow more smoothly to the water outlet after being filtered through the mesh holes, thereby avoiding water blockage and ensuring smooth water outlet.

[0018] As a preferred embodiment of the present embodiment, the trigger rib extends upward from the upper surface of the filter and is integrally formed with the filter; thus, the filter structure is provided with a trigger rib, which not only provides impurity filtering, but also is used to trigger the water outlet of the water tank to open. It has multiple uses and can reduce the overall number of components through component integration, thereby simplifying assembly and promoting compact arrangement of the structure; moreover, the filter as a whole can be easily disassembled for cleaning, which can prevent the surface of the trigger rib from being in contact with water for a long time and easily breeding bacteria, thereby ensuring safe and hygienic drinking water.

[0019] Furthermore, the trigger rib includes four prisms distributed in a cross shape, and the distribution range of the mesh extends to the space between two adjacent prisms; thus, the water in the water tank can flow along the prisms onto the filter screen, and by increasing the distribution range of the mesh, the water can be filtered through the mesh when flowing down between two adjacent prisms, which is beneficial to improving the filtering effect, and there is a larger surface area between two adjacent prisms to facilitate water conduction, guiding the water flow to the mesh to obtain sufficient filtration.

[0020] 3. As a preferred embodiment, the bottom wall of the receiving tank is provided with an upwardly protruding rib to lift the filter screen; thereby, by lifting the filter screen, it is possible to prevent the mesh from being tightly attached to the bottom wall of the receiving tank to cause water blockage, thereby ensuring smooth water outflow.

[0021] Alternatively, a bracket is provided at the bottom of the filter to isolate the mesh from the bottom wall of the receiving tank; thus, by raising the filter, the mesh can be prevented from being close to the bottom wall of the receiving tank to cause water blockage, thereby ensuring smooth water outflow.

[0022] 4. As a preferred embodiment, the top of the accommodating groove is provided with an annular rim forming the opening, and the lower surface of the first sealing ring is provided with an annular groove, and the rim is inserted into the groove; therefore, when installing the first sealing ring, the first sealing ring is pressed onto the rim so that the rim is inserted into the groove, which is convenient and secure to install.

[0023] The inner circumferential wall of the first sealing ring is inclined toward the center of the accommodating groove to form a closed end; thus, by forming a closed end on the inner circumferential wall of the first sealing ring, the sealing effect between the inner circumferential wall of the first sealing ring and the protrusion of the water tank can be strengthened to ensure reliable sealing.

[0024] A sealing rib abutting against the protrusion is provided on the inner wall of the first sealing ring; by providing the sealing rib, the water tank protrusion can be further tightened to improve the sealing effect.

[0025] 5. As a preferred embodiment, a reset piece is sleeved on the outer side of the push rod, and when the water tank is installed in place, the reset piece is in an elastic deformation state, and when the push rod is separated from the trigger rib, the reset piece drives the push rod to move so that the second sealing ring blocks the water outlet; thus, by providing the reset piece, when the water tank is disassembled, the reset piece can drive the push rod to move downward quickly so that the second sealing ring blocks the water outlet, so that the water outlet is sealed in time and effectively, which can prevent water leakage when there is residual water in the water tank, thereby improving the reliability of water tank disassembly.

[0026] As a preferred embodiment of the present embodiment, the bottom end of the push rod is provided with a limiting step protruding outward to limit the axial position of the reset member; thus, the limiting step can prevent the reset member from sliding down and off the push rod to ensure the reliability of the installation and use of the reset member.

[0027] As a preferred embodiment of the present embodiment, the reset member is a spring, and the elastic force of the spring is smaller than the gravity of the empty water tank; thus, when the empty water tank is installed, the gravity of the empty water tank can ensure that the water tank protrusion and the connector form an automatic and effective seal, and no water leakage will occur after the user subsequently adds water to the water tank.

[0028] 6. As a preferred embodiment, the second sealing ring is provided with a accommodating cavity, the top of the accommodating cavity is closed, and the bottom is provided with an installation opening, the push rod is inserted into the accommodating cavity through the installation opening and has an interference fit with the accommodating cavity; the upper end of the push rod is provided with an annular installation groove, and the installation opening is provided with an inwardly protruding installation portion to embed into the installation groove; thereby, the second sealing ring can be sleeved on the end of the push rod, and the interference fit can prevent the second sealing ring from falling off, and the installation portion can be embedded in the installation groove to strengthen the fitting effect between the second sealing ring and the side wall of the push rod, thereby improving the firmness of the installation of the second sealing ring, and since the top of the accommodating cavity is closed, water can be prevented from flowing into the fitting gap between the second sealing ring and the push rod, thereby ensuring the water outlet effect.

[0029] The outer diameter of the bottom surface of the second sealing ring is greater than the diameter of the water outlet; therefore, when the bottom surface of the second sealing ring is attached to the upper surface of the water outlet, the water outlet can be effectively sealed, thereby improving the sealing reliability.

[0048] like Figures 1 to 8 As shown, the present application provides a water dispenser with reliable installation, including a body 10 and a water tank 11 detachably mounted on the body 10, the body 10 is provided with a connector 12, the connector 12 has a receiving groove 121, the receiving groove 121 is provided with an opening 122 at the top and a water outlet hole 123 at the bottom, a first sealing ring 13 is provided at the opening 122, a trigger rib 14 extending upward is provided in the receiving groove 121, the water tank 11 is provided with a water outlet 111 and a ring-shaped protrusion 112 extending downward from the bottom of the water outlet 111, the The water outlet 111 and the protrusion 112 are connected to form a water outlet channel, and an axially movable push rod 15 is provided in the water outlet channel. The upper end of the push rod 15 is sleeved with a second sealing ring 16. The trigger rib 14 has a first position abutting against the bottom surface of the push rod 15 and a second position detached from the push rod 15. In the first position, the protrusion 112 is inserted into the opening 122 and the outer wall of the protrusion 112 is in contact with the inner wall of the first sealing ring 13. In the second position, the second sealing ring 16 blocks the water outlet 111.

[0049] The body 10 is provided with a connector 12, one end of the connector 12 is connected to the water tank 11, and the other end of the connector 12 (water outlet 123) is connected to the water outlet of the water dispenser through a connecting pipe to achieve water outlet. Figure 1 As shown, the machine body 10 is provided with a mounting seat 17 for placing the water tank 11, the connector 12 is arranged in the mounting seat 17, and the mounting seat 17 has a through hole 171 for exposing the opening 122 of the connector 12, and the top of the accommodating groove 121 and the lower surface of the edge of the through hole 171 can be used to clamp the first sealing ring 13 to improve the reliability of the installation of the first sealing ring 13. The protrusion 112 of the water tank 11 can be inserted into the opening 122 through the through hole 171, and fit with the first sealing ring 13 to form a seal. The water dispenser of the present application can ensure, during the installation process of the water tank 11, that the protrusion 112 of the water tank 11 and the connector 12 form a seal while the trigger rib 14 abuts against the push rod 15, thereby avoiding the problem of water leakage during the installation of the water tank 11 when the trigger rib 14 first pushes up the push rod 15 while the protrusion 112 of the water tank 11 and the connector 12 are not yet well sealed. It can also avoid the problem of water dripping from the water outlet of the water dispenser when the protrusion 112 of the water tank 11 and the connector 12 are sealed first and the trigger rib 14 pushes up the push rod 15 later. Therefore, the reliability of the installation of the water tank 11 is improved, and the user experience can be enhanced.

[0050] Specifically, by optimizing the sizes of the trigger rib 14, the top rod 15 and the protrusion 112, these multiple components are satisfied. When the water tank 11 is installed from top to bottom, the trigger rib 14 contacts the top rod 15, and the protrusion 112 can just fit the first sealing ring 13 to form a seal, thereby ensuring the installation effect of the water tank 11.

[0051] As a preferred embodiment of the present application, a filter screen 18 is further disposed in the receiving groove 121 . The filter screen 18 is provided with a plurality of mesh holes 181 . There is a gap between the mesh holes 181 and the bottom wall of the receiving groove 121 .

[0052] like Figure 4 and Figure 7 As shown, the filter 18 is disposed below the trigger rib 14. After the water in the water tank 11 flows into the receiving groove 121, it can be filtered through the filter 18, which can improve the quality of the water finally flowing out of the connector 12 and ensure the health of the user. Since there is a gap between the mesh 181 and the bottom wall of the receiving groove 121, the mesh 181 will not be close to the bottom wall of the receiving groove 121, so that the water can flow more smoothly to the water outlet 123 after being filtered through the mesh 181, which can avoid water blockage and ensure smooth water outlet.

[0053] The filter screen 18 can be a plate-shaped member or a cover structure, and has a plurality of mesh holes 181, the number and size of which can be set according to actual needs. In order to form a gap between the mesh holes 181 and the bottom wall of the receiving groove 121, any of the following methods can be used.

[0054] In one embodiment, Figure 2 As shown, the bottom wall of the receiving groove 121 is provided with a convex rib 124 protruding upward to lift the filter screen 18. In this embodiment, the filter screen 18 can be a flat plate structure.

[0055] In another embodiment, a bracket is provided at the bottom of the filter screen 18 to separate the mesh 181 from the bottom wall of the receiving groove 121. The bracket and the filter screen 18 can be an integral part or a separate part, and the bracket is, for example, cross-shaped or ring-shaped.

[0056] In another embodiment, Figure 4 As shown, the filter 18 includes a filter plate (with mesh holes 181 opened on the filter plate) and a flange 182 folded downward from the edge of the filter plate. The flange 182 can be supported on the bottom wall of the accommodating groove 121 to form a gap between the mesh holes 181 and the bottom wall of the accommodating groove 121.

[0057] Furthermore, the trigger rib 14 may be a separate component or may be integrally formed with the filter screen 18 .

[0058] In one embodiment, Figure 4 As shown, the trigger rib 14 extends upward from the upper surface of the filter screen 18 and is integrally formed with the filter screen 18 .

[0059] That is, the filter screen 18 structure of the present application is provided with a trigger rib 14, which not only provides impurity filtering, but also is used to trigger the water outlet 111 of the water tank 11 to open. It has multiple uses, and the overall number of components can be reduced through component integration, which can simplify assembly and promote compact arrangement of the structure; and the filter screen 18 as a whole is easy to disassemble and clean, which can prevent the surface of the trigger rib 14 from contacting water for a long time and easily breeding bacteria, thereby ensuring safe and hygienic drinking water. Preferably, the trigger rib 14 is arranged in the central area of ​​the filter screen 18.

[0060] The present application does not specifically limit the shape of the trigger rib 14 , and the cross section of the trigger rib 14 may be, for example, circular, square, polygonal, straight, cross-shaped, etc.

[0061] In one embodiment, Figure 4 As shown, the trigger rib 14 includes four prisms 141 distributed in a cross shape, and the distribution range of the mesh 181 extends to the space between two adjacent prisms 141 .

[0062] Four mesh holes 181 are formed on the filter 18, and the corresponding central angle between each two adjacent prisms 141 is 90 degrees (the center of the trigger rib 14 coincides with the center of the circle where the filter 18 is located). There is a corresponding mesh hole 181 between each two adjacent prisms 141. When the water tank 11 is discharged, the water flowing down from between the two adjacent prisms 141 can be filtered through the mesh hole 181, which is conducive to improving the filtering effect. In addition, there is a large surface area between the two adjacent prisms 141 to facilitate water conduction, and guide the water flow to the mesh hole 181 to obtain sufficient filtration.

[0063] As a preferred embodiment of the present application, the top of the accommodating groove 121 is provided with an annular rim 125 forming the opening 122 , and the lower surface of the first sealing ring 13 is provided with an annular groove 131 , and the rim 125 is inserted into the groove 131 .

[0064] like Figure 2 , Figure 3 and Figure 8 As shown, the first sealing ring 13 is a double-layer structure of inner and outer layers. When installing the first sealing ring 13, the first sealing ring 13 is pressed onto the surrounding edge 125 so that the surrounding edge 125 is inserted into the groove 131. The installation is convenient and reliable.

[0065] Furthermore, the inner circumferential wall of the first sealing ring 13 is inclined toward the center of the receiving groove 121 to form a closed end. That is, the diameter formed by the inner circumferential wall of the first sealing ring 13 gradually decreases from top to bottom, which can enhance the sealing effect of the inner circumferential wall of the first sealing ring 13 and the protrusion 112 of the water tank 11, ensuring reliable sealing.

[0066] Furthermore, a sealing rib 132 is provided on the inner wall of the first sealing ring 13 to abut against the protrusion 112. By providing the sealing rib 132, the protrusion 112 of the water tank 11 can be further tightened to improve the sealing effect.

[0067] As a preferred embodiment of the present application, a reset member 19 is sleeved on the outer side of the push rod 15. When the water tank 11 is installed in place, the reset member 19 is in an elastic deformation state. When the push rod 15 is separated from the trigger rib 14, the reset member 19 drives the push rod 15 to move so that the second sealing ring 16 blocks the water outlet 111.

[0068] like Figure 7 and Figure 8 As shown, when the water tank 11 is installed, the trigger rib 14 can lift the push rod 15 to open the water outlet 111. When the water tank 11 is disassembled, the reset member 19 can drive the push rod 15 to move downward quickly so that the second sealing ring 16 blocks the water outlet 111, so that the water outlet 111 is sealed in time and effectively, which can prevent water leakage when there is residual water in the water tank 11, thereby improving the reliability of the disassembly of the water tank 11.

[0069] Furthermore, the bottom end of the push rod 15 is provided with a limiting step 151 protruding outwards to limit the axial position of the reset member 19. Figure 5 As shown, the limiting step 151 can prevent the reset member 19 from sliding down and off the ejector rod 15, so as to ensure the reliability of the installation and use of the reset member 19. Figure 8 As shown, the upper end of the reset member 19 can be limited by the bottom surface of the water tank 11 at the edge of the water outlet 111.

[0070] The reset member 19 is, for example, a spring, and the elastic force of the spring is smaller than the gravity of the empty water tank 11 .

[0071] When the water tank 11 is installed, there is water in the water tank 11 and there is no water in the water tank 11. When there is water in the water tank 11, the overall gravity of the water tank 11 can ensure that the protrusion 112 is sealed with the connector 12 and the water tank 11 is installed in place. When the gravity of the empty water tank 11 is greater than the elastic force of the spring, when the empty water tank 11 is placed, the water tank 11 can be automatically installed in place under the gravity of the empty water tank 11 and the guidance of the first sealing ring 13, and the protrusion 112 and the connector 12 form an effective seal, so that the user can safely add water to the water tank 11. By installing the empty water tank 11 and then adding water to the water tank 11, the burden of the user can be reduced, which is very friendly to users with less strength.

[0072] As a preferred embodiment of the present application, the second sealing ring 16 is provided with a accommodating cavity 161, the top of the accommodating cavity 161 is closed, and a mounting opening 162 is provided at the bottom. The push rod 15 is inserted into the accommodating cavity 161 through the mounting opening 162 and has an interference fit with the accommodating cavity 161; the upper end of the push rod 15 is provided with an annular mounting groove 152, and the mounting opening 162 is provided with a mounting portion 163 protruding inwardly 112 to embed into the mounting groove 152.

[0073] like Figure 5 , Figure 6 and Figure 8 As shown, the second sealing ring 16 can be sleeved on the end of the top rod 15, and the interference fit can prevent the second sealing ring 16 from falling off, and the mounting portion 163 is embedded in the mounting groove 152 to strengthen the fitting effect between the second sealing ring 16 and the side wall of the top rod 15, which can improve the firmness of the installation of the second sealing ring 16. Since the top of the accommodating cavity 161 is closed, water can be prevented from flowing into the fitting gap between the second sealing ring 16 and the top rod 15, thereby ensuring the water outlet effect.

[0074] Furthermore, the outer diameter of the bottom surface of the second sealing ring 16 is greater than the diameter of the water outlet 111 .

[0075] like Figure 8 As shown, when the water tank 11 is disassembled, the bottom surface of the second sealing ring 16 is attached to the upper surface of the water outlet 111. The second sealing ring 16 has a large radial coverage area, which can enhance the sealing effect on the water outlet 111 and prevent water leakage.

[0076] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model.
