[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The water tank assembly according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0048] like Figure 1-Figure 3 As shown, the water tank assembly according to the embodiment of the utility model includes a water storage container 10, a water outlet pipe 20, a water channel control device 30 and a filtering device 600.

[0049] The water storage container 10 defines a water storage chamber 11, and one end of the water outlet pipe 20 extends into the water storage chamber 11 to a position close to the bottom wall and defines a water inlet 21. In this way, when the liquid in the water storage chamber 11 needs to be used and the liquid in the water storage chamber 11 flows out through the water outlet pipe 20, all the liquid in the water storage chamber 11 can enter the water outlet pipe 20 as much as possible, thereby improving the utilization rate of the liquid in the water storage chamber 11.

[0050] At least a portion of the water outlet pipe 20 is higher than the water outlet 22 of the water outlet pipe 20 , so that the liquid will flow out from the water outlet 22 only after the liquid level in the water outlet pipe 20 is higher than its highest position, making it difficult for the liquid in the water storage chamber 11 to leak at the water outlet 22 .

[0051] The water circuit control device 30 is connected to the water outlet pipe 20. When the outlet water pressure in the water outlet pipe 20 is greater than the starting pressure, the water circuit control device 30 connects the water storage chamber 11 and the water outlet 22. Specifically, when the position of the water storage container 10 is changed, such as when the water storage container 10 is lifted or placed, although the liquid in the water storage chamber 11 may be shaken, the outlet water pressure in the water outlet pipe 20 is less than the starting pressure at this time. The water circuit control device 30 disconnects the water storage chamber 11 and the water outlet 22 to prevent the liquid level in the water outlet pipe 20 from rising when the water storage container 10 is moved, thereby preventing the liquid from leaking from the water outlet 22.

[0052] The water channel control device 30 may be disposed at the water inlet 21 or in the water outlet pipe 20 , and no further restrictions are imposed here.

[0053] The filter device 600 is arranged on the water channel control device 30 and is located upstream of the water channel control device 30 in the direction of water flow. The filter device 600 can filter the liquid at the front end of the water channel control device 30 to prevent the water channel control device 30 from being contaminated by impurities in the liquid. At the same time, it can prevent impurities in the liquid from entering the water outlet pipe 20 to prevent impurities in the liquid from damaging the water channel components at the rear end of the filter device 600.

[0054] According to the water tank assembly of the embodiment of the utility model, it is possible to prevent the liquid in the water storage chamber 11 from leaking out from the water outlet 22 when the water storage container 10 is moved, and at the same time, the liquid can be filtered to prevent impurities in the liquid from damaging the water channel control device 30 and the water channel components at the rear end of the water channel control device 30.

[0055] The water tank assembly according to a specific embodiment of the utility model is described below with reference to the accompanying drawings.

[0056] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the water tank assembly includes a water storage container 10 , a water outlet pipe 20 , a water channel control device 30 and a filtering device 600 .

[0057] In some embodiments of the present utility model, the water channel control device 30 includes a shell 300 and a control component 400. The shell 300 defines a first water passage chamber 33. The first water passage chamber 33 communicates with the water outlet 22 and the water storage chamber 11. The control component 400 is disposed in the first water passage chamber 33 to control the opening and closing of the first water passage chamber 33. When the outlet water pressure in the outlet pipe 20 is greater than the starting pressure, the control component 400 opens the first water passage chamber 33.

[0058] When the position of the water storage container 10 is changed, for example, when the water storage container 10 is lifted or placed, although the liquid in the water storage chamber 11 will shake, the water outlet pressure in the water outlet pipe 20 is less than the starting pressure at this time, and the water circuit control device 30 disconnects the first water passage chamber 33 to prevent the liquid in the water storage chamber 11 from entering the water outlet pipe 20 when the water storage container 10 is moved, so as to prevent the liquid level in the water outlet pipe 20 from rising and leaking out of the water outlet 22.

[0059] In some embodiments, the water tank assembly also includes a driving member, which is connected to the water outlet pipe 20, and is used to drive the liquid in the water storage chamber 11 to be discharged from the water outlet 22 along the water outlet pipe 20. When the driving member is working, the water outlet pressure of the water outlet pipe 20 is greater than the starting pressure. At this time, the control member 400 connects the first water passage chamber 33. At this time, the first water passage chamber 33 connects the water storage chamber 11 and the water outlet 22, so that the liquid in the water storage chamber 11 can flow out from the water outlet 22 through the water outlet pipe 20.

[0060] In some optional embodiments of the present invention, Figure 3 , Figure 8 As shown, the first water passage chamber 33 is connected to the water storage chamber 11 through the first water passage port 51, and the control member 400 includes a blocking portion 411 and an elastic member 412. The blocking portion 411 is used to open and close the first water passage port 51, and the elastic member 412 is disposed between the housing 300 and the blocking portion 411, and is used to drive the blocking portion 411 to close the first water passage port 51. When the waterway control device 30 is in an initial state, the elastic member 412 makes the blocking portion 411 abut against the first water passage port 51 and the elastic member 412 stores elastic potential energy, and the elastic member 412 exerts an elastic force on the blocking portion 411, so that the blocking portion 411 can fully close the first water passage port 51.

[0061] Specifically, when the water pressure in the water outlet pipe 20 overcomes the elastic potential energy of the elastic member 412, the blocking portion 411 moves under the action of the water pressure, so that the blocking portion 411 moves to open the first water outlet 51. At this time, the liquid in the water storage chamber 11 can enter the first water passage chamber 33 from the first water passage 51. At this time, the first water passage chamber 33 connects the water storage chamber 11 and the water outlet 22, so that the liquid in the water storage chamber 11 can flow out from the water outlet 22 through the water outlet pipe 20.

[0062] Among them, when the water storage container 10 is moved, although the water in the water storage chamber 11 shakes, it is not enough to overcome the elastic potential energy of the elastic member 412. At this time, the blocking portion 411 still closes the first water outlet 51 to prevent the liquid in the water storage chamber 11 from entering the water outlet pipe 20, and to prevent the liquid from leaking from the water outlet 22 when the water storage container 10 is moved.

[0063] like Figure 3As shown, in this embodiment, the water channel control device 30 is arranged at the lower end of the water outlet pipe 20, and the elastic member 412 has a downward elastic force on the blocking portion 411, so that the blocking portion 411 and the wall of the first water passage chamber 33 are stopped and matched, thereby enabling the blocking portion 411 to close the first water passage 51. The water tank assembly also includes a driving member, which is connected to the water outlet pipe 20, and the driving member is used to drive the liquid in the water storage chamber 11 to be discharged from the water outlet 22 along the water outlet pipe 20.

[0064] When the driving member is working, the water outlet pressure of the water outlet pipe 20 is greater than the elastic potential energy of the elastic member 412, and the blocking portion 411 moves upward, the blocking portion 411 is disengaged from the wall of the first water passage chamber 33, and the blocking portion 411 opens the first water passage 51. When the driving member stops working, under the action of the elastic member 412, the blocking portion 411 moves downward to close the first water passage 51 again.

[0065] In some optional embodiments of the present invention, Figure 6 , Fig.10 and Fig.14 As shown, the inlet 331 of the first water passage chamber 33 is connected to the water storage chamber 11, and the inlet 331 and the outlet 332 of the first water passage chamber 33 are connected through the second water passage port 423. The control member 400 includes a diaphragm body 421 and a plurality of diaphragm petals 422. The diaphragm body 421 defines the second water passage port 423. The plurality of diaphragm petals 422 can be connected to the diaphragm body 421 in an openable and closable manner to jointly open and close the second water passage port 423. The diaphragm petals 422 are made of elastic material, and the diaphragm petals 422 can undergo elastic deformation to open or close the second water passage port 423.

[0066] In some embodiments, the water tank assembly further includes a driving member connected to the water outlet pipe 20 , and the driving member is used to drive the liquid in the water storage chamber 11 to be discharged from the water outlet 22 along the water outlet pipe 20 .

[0067] When the driving member is working, when the water outlet pressure of the water outlet pipe 20 is greater than the starting pressure, under the action of the driving member, the diaphragm 422 will be elastically deformed, and the multiple diaphragms 422 will open the second water passage 423, and the liquid in the water storage chamber 11 can enter the first water passage chamber 33 from the inlet 331 of the first water passage chamber 33. At this time, the water in the first water passage chamber 33 flows to the water outlet 22 through the second water passage 423, so as to conduct the water storage chamber 11 and the water outlet 22, so that the liquid in the water storage chamber 11 can flow out from the water outlet 22 through the water outlet pipe 20. When the driving member stops working, the multiple diaphragms 422 will resume their deformation to close the second water passage 423 together again.

[0068] In some optional embodiments of the present invention, Figure 2 , Figure 3As shown, the housing 300 has a plug-in portion 34 , which defines a water passage 342 , and the plug-in portion 34 is plug-fitted with the water outlet pipe 20 to allow the water channel control device 30 to communicate with the water outlet pipe 20 .

[0069] Among them, the water passage 342 connects the first water passage chamber 33 and the water outlet pipe 20. When the water outlet pressure in the water outlet pipe 20 is greater than the starting pressure, the first water passage chamber 33 connects the water storage chamber 11 and the water outlet 22, so that the liquid in the water storage chamber 11 can flow out from the water outlet 22 through the water outlet pipe 20.

[0070] In some specific embodiments of the present invention, Figure 3 As shown, the plug-in portion 34 is plugged into the water inlet 21, and the outer peripheral wall of the plug-in portion 34 has a guiding slope 341 for guiding the plug-in portion 34 to be plugged into the water outlet pipe 20, so as to achieve smooth plug-in cooperation between the plug-in portion 34 and the water outlet pipe 20, and then set the waterway control device 30 at the water inlet 21.

[0071] In some embodiments, the waterway control device 30 is disposed at the lower end of the water outlet pipe 20, and the plug-in portion 34 extends in the up-down direction (it should be understood here that the above-mentioned direction limitation is only for the convenience of describing the accompanying drawings, and will not limit the actual setting position and direction of the water tank assembly). In the direction from bottom to top, the guide slope 341 extends in the direction close to the axis of the water passage 342, that is, the size of the upper end of the plug-in portion 34 is smaller, and the size of the lower end is larger. When the plug-in portion 34 is plugged into the water outlet pipe 20, the upper end of the plug-in portion 34 first extends into the water outlet pipe 20, so that the size of the upper end of the plug-in portion 34 is smaller, which is convenient for reducing the difficulty of matching the plug-in portion 34 with the water outlet pipe 20. When the waterway control device 30 is moved upward, the distance between the wire slope and the side wall of the water outlet pipe 20 gradually decreases, thereby achieving smooth plug-in matching between the plug-in portion 34 and the water outlet pipe 20.

[0072] In some optional embodiments of the present invention, Figure 3 , Figure 8 and Fig.14 As shown, the filter device 600 includes a support frame 70 and a first filter element. The support frame 70 is fixed to the shell 300 and defines a second water passage chamber 71 with the shell 300. The second water passage chamber 71 communicates with the water storage chamber 11 and the first water passage chamber 33. The first filter element is arranged on the support frame 70. When the liquid in the water storage chamber 11 enters the second water passage chamber 71, the first filter element can filter impurities in the liquid to prevent the impurities in the liquid from entering the second water passage chamber 71 and the first water passage chamber 33, preventing the impurities from damaging the water path control device 30, and preventing the impurities in the liquid from damaging the water path components at the rear end of the water path control device 30.

[0073] In some specific embodiments of the present invention, Figure 3As shown, the first filter element includes a filter screen 61, and the filter screen 61 includes a circumferential filter screen 611 and an end filter screen 612. The circumferential filter screen 611 surrounds the outer circumference of the shell 300, and the end filter screen 612 is located at one end of the shell 300 with a first gap 81 therebetween. One end of the shell 300 defines an inlet 331 of the first water passage chamber 33.

[0074] Specifically, the support frame 70 can support the positions of the circumferential filter screen 611 and the end filter screen 612, so that the circumferential filter screen 611 and the end filter screen 612 can filter the liquid entering the second water passage chamber 71, so that there is a first gap 81 between the end filter screen 612 and the inlet 331 of the first water passage chamber 33, so as to prevent the end filter screen 612 from blocking the inlet 331 of the first water passage chamber 33, thereby allowing the liquid in the second water passage chamber 71 to smoothly enter the first water passage chamber 33.

[0075] Among them, Figure 3 As shown, in the embodiment where the first water passage chamber 33 is connected to the water storage chamber 11 through the first water passage port 51, the inlet 331 of the first water passage chamber 33 is the first water passage port 51, and the end filter screen 612 is located at one side of the first water passage port 51 and has a first gap 81 between the end filter screen 612 and the first water passage port 51 to prevent the end filter screen 612 from blocking the first water passage port 51, thereby allowing the liquid in the second water passage chamber 71 to smoothly enter the first water passage chamber 33.

[0076] In some specific embodiments of the present invention, Figure 8 As shown, the first filter element includes filter cotton 621, which is arranged in the second water passage chamber 71 and covers the inlet 331 of the first water passage chamber 33. The liquid in the water storage chamber 11 flows through the filter cotton 621 and enters the first water passage chamber 33, so that the filter cotton 621 is used to filter the liquid to prevent impurities in the liquid from entering the first water passage chamber 33 and to prevent impurities from damaging the water channel control device 30 and the water channel components at the rear end of the water channel control device 30.

[0077] In some embodiments, Figure 8 , Fig.10 As shown, the shell 300 has a plurality of spaced stop portions 35 on one side facing the filter cotton 621, and each stop portion 35 abuts against the filter cotton 621 so that a second gap 82 is provided between the shell 300 and the filter cotton 621, so as to separate the filter cotton 621 and the inlet 331 of the first water passage chamber 33, thereby preventing the filter cotton 621 from blocking the inlet 331 of the first water passage chamber 33, so that the liquid filtered by the filter cotton 621 can smoothly enter the first water passage chamber 33 from the inlet 331 of the first water passage chamber 33.

[0078] In some specific embodiments of the present invention, Figure 3As shown, the water channel control device 30 is connected to the water inlet 21, and the wall of the support frame 70 opposite to the inlet 331 of the first water passage chamber 33 is provided with a third water passage 53, and the water in the water storage chamber 11 can enter the second water passage chamber 71 from the third water passage 53.

[0079] Among them, the outer surface of the wall of the support frame 70 has a plurality of support protrusions 72, the support protrusions 72 abut against the bottom wall of the water storage chamber 11, and a third gap 83 is provided between the outer surface of the wall and the bottom wall of the water storage chamber 11 to separate the bottom wall of the water storage chamber 11 and the third water outlet 53, so as to prevent the bottom wall of the water storage chamber 11 from blocking the third water outlet 53, thereby allowing the water in the water storage chamber 11 to enter the second water outlet 71 after being filtered by the filter cotton 621 through the third water outlet 53.

[0080] In some embodiments, Figure 6-Figure 8 As shown, the support protrusion 72 is a support column, which is engaged with the bottom wall of the water storage chamber 11 to define a third gap 83 between the third water outlet 53 and the bottom wall of the water storage chamber 11 to prevent the bottom wall of the water storage chamber 11 from blocking the third water outlet 53, so that the liquid in the water storage chamber 11 can pass through the third water outlet 53 and enter the second water outlet 71 after being filtered by the filter cotton 621.

[0081] In some embodiments, Fig. 9 , Fig.10 As shown, the supporting protrusion 72 is an arc-shaped protrusion, which is abutted against the bottom wall of the water storage chamber 11 to define a third gap 83 between the third water outlet 53 and the bottom wall of the water storage chamber 11 to prevent the bottom wall of the water storage chamber 11 from blocking the third water outlet 53, so that the liquid in the water storage chamber 11 can flow to the second water outlet 71 after being filtered by the filter cotton 621 through the third water outlet 53.
