Abstract
Description
Technical Field
[0001] The utility model relates to the field of water tanks, in particular to a water tank. Background Art
[0002] For the kitchen, the sink is very important. The sink is used to wash dishes, chopsticks, ingredients, etc. Therefore, the sink needs to store water when necessary, and needs to be drained after cleaning.
[0003] In the prior art, a water tank includes a water tank body, a drain hole is provided on the bottom wall of the water tank body, a drain cup is installed in the drain hole, a small filter adapted to the cup body is provided in the cup body, and a sealing assembly and a spring core can be provided below the cup body. This structure has at least the following defects:
[0004] ①. Since the drain cup is generally a universal part, the radial size of the drain cup is limited and small, which makes the small filter installed in the drain cup small in size. When a lot of residues such as leftovers are poured into the sink, the residues can easily fill up the small filter and block the small filter, making it impossible for the small filter to drain. The user can only manually remove the small filter to clean the blocked residue and then put it back into the drain cup. When there is still water in the sink, removing the small filter can easily cause the residue to enter the sewer, which may cause the sewer to be blocked.
[0005] ②. Since the drain cup cavity is small and the small filter is completely set in the narrow cup cavity, when too much residue accumulates, it may also hinder the small filter from rising and falling. When the small filter is pressed, the elastic force of the spring core is not enough to lift the small filter, resulting in the seal of the sealing component cannot be released, affecting drainage. The user has to take out or lift the small filter to drain.
[0006] Therefore, the existing small filter structure brings inconvenience to users, and it is necessary to improve and optimize the existing sink. Utility Model Content
[0007] The utility model aims to solve at least one of the problems in the prior art. To this end, the utility model provides a water tank with a simple structure, a large filter area and fast water discharge.
[0008] The technical solution adopted by the utility model to solve its technical problems is:
[0009] A water tank comprising:
[0010] A water tank body, wherein a water drain hole is provided on the bottom wall of the water tank body, and a first sink groove is further provided on the bottom wall of the water tank body, wherein the water drain hole is provided in the first sink groove, and a radial dimension of the first sink groove is larger than a radial dimension of the water drain hole;

[0012] a first filter screen, disposed in the first sink, wherein the radial dimension of the first filter screen is larger than the cup cavity dimension of the lower water cup;
[0013] A bouncing core is provided in the lower water cup and is located below the first filter screen;
[0014] A sealing assembly connected to the spring core;
[0015] The first filter screen is pressed, and the spring core is driven by the first filter screen to drive the sealing component to seal or open the water channel at the bottom of the water cup.
[0016] Optionally, a second filter is provided in the cup cavity of the lower water cup, the bouncing core and the sealing assembly are located below the second filter, a first push rod is provided on the second filter, the first push rod is in contact with or close to the first filter, and the first filter pushes the bouncing core and the sealing assembly to move through the first push rod and the second filter.
[0017] Optionally, a second filter is not provided in the cup cavity of the lower water cup, and a second push rod is provided on the sealing assembly. The second push rod abuts against or is close to the first filter, and the first filter pushes the bouncing core and the sealing assembly through the second push rod.
[0018] Optionally, the first filter screen is provided with a flange, and a second sink is provided at the bottom of the water tank body, the second sink is located above the first sink, and the flange is located in the second sink.
[0019] Optionally, a handle is provided on the first filter screen.
[0020] Optionally, the first filter screen is square, circular or triangular, and the first sink is correspondingly configured to be square, circular or triangular.
[0021] Optionally, the spring core is arranged below the sealing assembly, and the two are fixedly connected by threads.
[0022] Optionally, the upper edge of the lower water cup is pressed against the edge of the drain hole, a thread is provided on the outer wall of the lower water cup, and the lower water cup further comprises a sleeve, which is threadedly connected to the lower water cup to fix the lower water cup.
[0023] The utility model has at least one of the following beneficial effects: the utility model has a first sink groove provided on the bottom wall of the water tank body, the drain hole is provided in the first sink groove, the radial size of the first sink groove is larger than the radial size of the drain hole; the first filter screen is provided in the first sink groove, the radial size of the first filter screen is larger than the cup cavity size of the drain cup; the bouncing core is provided in the drain cup and is located below the first filter screen; the sealing assembly is connected to the bouncing core; when the first filter screen is pressed, the bouncing core is driven by the first filter screen to drive the sealing assembly to seal or open the drain channel at the bottom of the drain cup, thereby abandoning the structure of directly providing the filter screen in the cup cavity of the drain cup in the prior art. Therefore, the first filter has a larger area than the filter in the drain cup in the prior art, and can retain more residues. The residues in the sink are distributed over the large area of the first filter, which is not likely to completely clog the mesh of the first filter. Therefore, the first filter, as a large-area filter, is easier to drain. At the same time, the first trough and the first filter are separated from the small space of the drain cup, so that residues are not likely to accumulate between the first trough and the first filter and hinder the lifting of the first filter. Therefore, when the first filter is pressed, the elastic force of the spring core can easily lift the first filter, thereby releasing the sealing function of the sealing assembly, and the accumulated water in the sink is easily drained away.
[0024] In addition, when a second filter is provided in the cup cavity of the lower water cup, the water sink described in the embodiment of the present invention has a double-layer filter structure consisting of a first filter and a second filter, which realizes layered and multi-stage filtration of residues, effectively blocks coarse and fine residues and is not prone to clogging; in addition, after long-term use, even if one of the filters is damaged, it will not affect the filtering effect of the water sink on the residue, and the water sink can continue to be used normally.

[0035] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is any conflict, the embodiments and features in the embodiments described below can be combined with each other in any manner.
[0036] Many different implementations or examples are provided below to implement the structure of the present invention.
[0037] See also Figures 1-8 A water tank according to an embodiment of the present invention comprises a water tank body 1, which can be made of stainless steel. A water hole 2 is provided on the bottom wall of the water tank body 1, and a first sink 3 is further provided on the bottom wall of the water tank body 1. The water hole 2 is provided in the first sink 3, and the radial dimension of the first sink 3 is larger than the radial dimension of the water hole 2; a water cup 4 is connected to the position of the water hole 2 of the water tank body 1. In some embodiments, as Figure 2 or Figure 8As shown, the upper edge of the lower water cup 4 is pressed against the edge of the drain hole 2, and a thread is provided on the outer wall of the lower water cup 4, and also includes a sleeve 5, which is threadedly connected to the lower water cup 4. As the sleeve 5 is tightened, the upper edge of the lower water cup 4 and the sleeve 5 will tightly clamp the edge of the drain hole 2, thereby the lower water cup 4 is firmly and reliably fixed on the sink body 1, and the bottom end of the lower water cup 4 is used to connect the drain pipe, and the lower water cup 4 has a cup cavity; the first filter screen 6 is arranged in the first sink 3, and the first filter screen 6 can be directly placed in the first sink 3. The first sink 3 can guide the up and down movement of the first filter screen 6, and the diameter of the first filter screen 6 The size of the cup cavity is larger than that of the lower water cup 4; it also includes a bouncing core 7. In this embodiment, the working principle of the bouncing core 7 is as follows: when the bouncing core is pressed, the overall length of the bouncing core becomes shorter, and when pressed again, the overall length of the bouncing core becomes longer. Thus, the bouncing core 7 can drive the following sealing component 8 to open or close the water channel. The specific structure of the bouncing core is a well-known technology and will not be elaborated here. The bouncing core 7 is arranged in the lower water cup 4 and is located below the first filter screen 6; the sealing component 8 is connected to the bouncing core 7. In some embodiments, the bouncing core 7 is arranged below the sealing component 8, and the two are fixed with threads, such as Figure 8 As shown, in some embodiments, the sealing assembly 8 includes a plastic body and a rubber ring disposed thereon. Pressing the first filter screen 6 causes the spring core 7 to be driven by the first filter screen 6, thereby driving the sealing assembly 8 to seal or open the drain channel 41 at the bottom of the drain cup 4. In this embodiment, the first filter screen 6 has a larger surface area than the filter screens in the drain cup in the prior art. This allows for more debris to be trapped within the first filter screen 6. Debris within the sink is distributed over the large surface area of the first filter screen, making it less likely to completely clog the first filter screen's mesh. Therefore, the first filter screen 6, as a large-area filter, facilitates drainage. Furthermore, the first trough 3 and the first filter screen 6 are separated from the confined cavity of the drain cup 4, preventing debris from accumulating between the first trough 3 and the first filter screen 6 and hindering its movement. Therefore, when the first filter screen 6 is pressed, the spring force of the spring core 7 easily lifts the first filter screen 6, releasing the sealing function of the sealing assembly 8 and allowing the accumulated water in the sink to be easily drained.
[0038] See Figure 2As shown, in some embodiments of the present invention, a second filter 9 is disposed in the cup cavity of the lower water cup 4, the spring core 7 and the sealing assembly 8 are located below the second filter 9, and a first push rod 91 is disposed on the second filter 9. The first push rod 91 and the second filter 9 can be integrally formed or separately connected. The first push rod 91 abuts or is close to the first filter 6. The term "close to the first filter 6" means that although there is no direct contact between the two, when the first filter 6 is pressed, the first filter 6 can contact the first push rod 91, thereby ultimately pushing the spring core 7 into action. The first filter 6 pushes the spring core 7 and the sealing assembly 8 into action via the first push rod 91 and the second filter 9. This structure provides the sink with a double-layer filter structure consisting of the first filter 6 and the second filter 9, achieving layered, multi-stage filtration of residues, effectively blocking coarse and fine residues and preventing clogging. In addition, after long-term use, even if one of the filters is damaged, the sink's filtering function is not affected, and the sink can continue to function normally.
[0039] See Figure 8 As shown, in some embodiments of the present invention, the second filter screen is not provided in the cup cavity of the lower water cup 4, and a second push rod 81 is provided on the sealing assembly 8. The second push rod 81 abuts against or is close to the first filter screen 6, and the first filter screen 6 pushes the spring core 7 and the sealing assembly 8 to move through the second push rod 81. Manufacturers can equip Figure 2 The second filter screen, seal assembly, and Figure 8 The sealing assembly shown can be installed in the sink by the user by selecting accessories as needed.
[0040] See Figure 2-Figure 4 、 Figure 8 As shown, in some embodiments of the present invention, a flange 61 is provided on the first filter screen 6, and a second trough 11 is provided at the bottom of the sink body 1. The second trough 11 is located above the first trough 3, and the flange 61 is located in the second trough 11. This structure improves the structural strength of the first filter screen 6 and, at the same time, makes the installation of the first filter screen 6 in the sink body 1 more fitting and beautiful.
[0041] See Figure 2-Figure 4 、 Figure 8 As shown, in some embodiments of the present invention, a handle portion 62 is provided on the first filter screen 6, so that the user can conveniently hold the handle portion 62 to take out the first filter screen 6 for cleaning.
[0042] In some embodiments of the present invention, the first filter screen 6 is square, circular or triangular, and the first trough 3 is correspondingly set to be square, circular or triangular; it can be understood that the contours of the first filter screen 6 and the first trough 3 include but are not limited to the above-mentioned shapes.
[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
