Description

Technical Field

[0001] The invention relates to the field of bathrooms, and in particular to an overflow and drainage device. Background Art

[0002] Most of the current kitchen and bathroom basins are equipped with overflow holes, overflow channels or overflow rings, which affect the aesthetics of the basins, easily create sanitary dead corners, and the overflow channels are easily blocked and difficult to clean.

When the water level in the overflow trough slowly rises, the float slowly moves upward under the action of buoyancy, the movable conductor is driven by the drive arm to move away from between the two contacts, and the solenoid valve is powered off and closed, preventing the water pipe from continuing to supply water to the faucet, thereby avoiding overflow and wasting water.

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0026] like Figures 1 to 3 As shown, the present invention provides an overflow and drainage device, comprising a main body shell 2, a connecting pipe 1, a first driving mechanism 3, a second driving mechanism (not marked in the figure) and a blocking mechanism 5; a water inlet hole 21 is provided on the side wall of the main body shell 2, a first groove 22 is provided on the bottom of the main body shell 2, one end of the connecting pipe 1 is connected to the water inlet hole 21, and the other end of the connecting pipe 1 is connected to a water containing device (not marked in the figure), the main body shell 2, the connecting pipe 1 and the water containing device (not marked in the figure) form a communicating vessel, and the blocking mechanism 5 is provided at the first groove 22 and is used to block the water flow The first driving mechanism 3 is arranged above the blocking mechanism 5 and is connected with the blocking mechanism 5. When the water level in the main body shell 2 reaches the first driving mechanism 3, the first driving mechanism 3 drives the blocking mechanism 5 to move upward under the buoyancy of the water so that the water inlet hole 21 is connected with the water outlet hole 23 to achieve overflow. The second driving mechanism (not marked in the figure) is arranged below the blocking mechanism 5 and abuts against it, and is used to drive the blocking mechanism 5 to move upward so that the water inlet hole 21 is connected with the water outlet hole 23 to achieve drainage.

[0027] In the present invention, the main body shell 2, the connecting pipe 1 and the water storage device (not marked in the figure) form a communicating vessel, so the water level height in the main body shell 2 is consistent with the water level height in the water storage device; the user injects water into the water storage device, and as the water level in the water storage device continues to rise, the water level in the main body shell 2 also rises accordingly. When the water level in the main body shell 2 reaches the first driving mechanism 3, the first driving mechanism 3 floats due to the buoyancy of water, thereby driving the blocking mechanism to rise upward. At this time, since the water inlet 21 is connected with the water outlet 23, overflow is achieved, avoiding the water in the water storage device from overflowing and causing trouble to the user. When the water level in the main body shell 2 drops after the overflow, the first driving mechanism drops due to its own gravity. At this time, the blocking mechanism separates the water inlet and the water outlet, and the water storage device starts to store water. When the user needs to discharge the sewage in the water storage device after use, the second driving mechanism is pressed to move the blocking mechanism 5 upward. At this time, since the water inlet 21 is connected with the water outlet 23, drainage is achieved.

[0028] Therefore, by adopting the present invention, there is no need to additionally open an overflow hole, overflow channel or overflow ring on the water holding device, so that the design of the water holding device can be more simple and beautiful, and there are no sanitary dead corners; at the same time, under the joint action of the first driving mechanism and the blocking mechanism, the overflow function of the water holding device is realized to avoid the trouble caused by water overflow, and the first driving mechanism can ensure that the amount of water used in the water holding device remains unchanged to meet the water consumption demand of the user; in addition, through the linkage action of the second driving mechanism and the blocking mechanism, the sewage discharge function of the water holding device is realized, and there is no need to touch the sewage for the second time, which is clean and hygienic.

[0029] Preferably, the first driving mechanism 3 includes a floating module 31 and a first connecting module 32. The floating module 31 is arranged at the overflow water level height in the main body shell 2 and is sealed and abutted against the inner wall of the main body shell 2. The floating module 31 is also connected to the blocking mechanism 5 through the first connecting module 32. When the water level in the main body shell 2 reaches the overflow water level height, the floating module 31 drives the blocking mechanism 5 to move upward under the buoyancy of water to connect the water inlet hole 21 with the water outlet hole 23 to achieve overflow.

[0030] It should be noted that, in the present embodiment, the floating module 31 is arranged at the overflow water level height in the main body shell 2 (which is consistent with the overflow water level height of the water holding device, and a suitable overflow water level height can be set according to user needs, and specifically, the overflow water level height can be adjusted by adjusting the length of the first connecting module) and is sealed against the inner wall of the main body shell 2; since the floating module 31 is sealed against the inner wall of the main body shell, the internal space of the main body shell can be fully utilized, thereby ensuring that the cross-sectional area of ​​the floating module 31 is large enough, so that the buoyancy force exerted on the floating module is sufficient to overcome the sum of the gravity of the floating module, the first connecting module and the blocking mechanism.

[0031] like Figure 5As shown, preferably, a cover body 7 is provided above the main body shell 2, at least two snap holes (not marked in the figure) are provided on the side wall of the main body shell 2, a snap mechanism 8 and a second groove 71 are provided on the cover body 7, a plurality of openings 72 are provided at the bottom of the second groove 71, the snap mechanism 8 includes a snap pipe 81, a first pressing module 82 and at least two snap modules (not marked in the figure); at least two first openings 811 are provided on the side tube wall of the snap pipe 81, a second opening 812 is provided on the upper tube wall of the snap pipe 81, a third groove 813 is provided on the lower tube wall of the snap pipe 81, and the third groove 813 is provided just below the second opening 812; the first pressing module 82 includes a first pressing unit 821 and a third spring 822, The first pressing unit 821 passes through the opening 72 on the second groove 71 and the second opening 812 on the buckle pipe 81 and is connected to the bottom of the third groove 813 through the second spring 822; the buckle module (not marked in the figure) includes a buckle 831, a connecting line 832, a baffle 833 and a first spring 834, the buckle 831 passes through the first opening 811 and is connected to the first pressing unit 821 through the connecting line 832, and the buckle 831 is also connected to the baffle 833 through the first spring 834; the first pressing unit 821 is pressed to move it into the third groove 813, and the buckle 831 is driven to move along the inside of the buckle pipe 81 through the connecting line 832 to squeeze the first spring 834.

[0032] It should be noted that, in the present embodiment, the cover body is fixed to the main body shell by at least two clips 831 on the cover body and the clip holes on the main body shell, so as to ensure the stability of the cover body; when the cover body needs to be disassembled, the first pressing unit 821 is pressed to move it into the third groove 813, and the clip 831 is driven by the connecting line 832 to move along the inside of the clip pipe 81 to squeeze the first spring 834, so as to simultaneously move at least two clips out of the corresponding clip holes, thereby realizing the disassembly of the cover body, which has the advantages of easy disassembly and simple structure; a second groove 71 is provided on the cover body, and a plurality of openings 72 are provided at the bottom of the second groove 71, and the second groove is used to provide an installation position.

[0033] like Figures 1 to 4As shown, the second driving mechanism (not marked in the figure) includes a second pressing module 41, a second connecting module 42 and a bouncing module 43. The second connecting module 42 is connected to the second pressing module 41 and is connected to the bouncing module 43 through the opening 72 on the second groove 71. The upper end of the bouncing module 43 abuts against the blocking mechanism 5. The bouncing module 43 moves up and down under the pressing action of the second pressing module 41 and the second connecting module 42 to enable the blocking mechanism 5 to move up and down.

[0034] It should be noted that the upper end of the bouncing module 43 is in contact with the blocking mechanism 5. When sewage needs to be discharged, the second pressing module is pressed and a downward pressure is applied to the bouncing module through the second connecting module. At this time, the bouncing module bounces up, thereby driving the blocking mechanism to rise. At this time, since the water inlet hole 21 and the water outlet hole 23 are connected, drainage is achieved. When drainage is not needed, the second pressing module is pressed again and a downward pressure is applied to the bouncing module through the second connecting module. At this time, the bouncing module contracts and the blocking mechanism descends under the action of gravity. At this time, the blocking mechanism separates the water inlet hole 21 and the water outlet hole 23. Therefore, when draining water, this embodiment does not need to touch the sewage for a second time, which is clean and hygienic.

[0035] Furthermore, the floating module 31 is provided with a first through hole (not marked in the figure), the first connecting module 32 is provided with a second through hole (not marked in the figure), the blocking mechanism 5 is provided with a third through hole (not marked in the figure), and the second connecting module 42 is connected to the bouncing module 43 via the opening 72 on the second groove 71, the first through hole (not marked in the figure), the second through hole (not marked in the figure) and the third through hole (not marked in the figure) in sequence.

[0036] It should be noted that, in the present embodiment, the second connecting module 42 is connected to the bouncing module 43 in sequence through the opening 72 on the second groove 71, the first through hole (not marked in the figure), the second through hole (not marked in the figure) and the third through hole (not marked in the figure), and the cover body, the first driving mechanism, the second driving mechanism and the blocking mechanism are designed as an integrated whole, which can reduce the usable space inside the main shell. When it is necessary to clean the blocking mechanism, the first driving mechanism or the second driving mechanism, it is only necessary to press the first pressing unit 821 to move it into the third groove 813, and drive the buckle 831 to move along the inside of the buckle pipe 81 through the connecting line 832 to squeeze the first spring 834, thereby simultaneously removing at least two buckles from the corresponding buckle holes, thereby realizing the disassembly of the cover body, and at the same time pulling out the first driving mechanism, the second driving mechanism and the blocking mechanism for regular cleaning and maintenance or adjusting the length of the first connecting module to select a suitable overflow water level height.

[0037] More preferably, the overflow and drainage device also includes a debris filtering mechanism (not marked in the figure), and the debris filtering mechanism (not marked in the figure) includes a filtering module 91 and a third connecting module 92, and the filtering module 91 is arranged at the water outlet 23, and the filtering module 91 is connected to the bouncing module 43 through the third connecting module 92.

[0038] It should be noted that in order to prevent large particles of debris in the water from clogging the water outlet, a debris filtering mechanism is provided at the water outlet in this embodiment, and the debris filtering mechanism is connected to the bouncing module. Therefore, when the waterway is blocked, the cover body and the debris filtering mechanism can be pulled out together for cleaning by opening the cover body, which has the advantage of filtering debris.

[0039] Preferably, the overflow and drainage device further includes a reminder mechanism 6, which includes a first liquid level sensor module 61, a second liquid level sensor module 62, a speaker module 63 and an LED indicator module 64; the first liquid level sensor module 61 is arranged at the overflow water level height of the main body shell 2 and is used to detect the overflow water level signal in the main body shell 2, the second liquid level sensor module 62 is arranged at the blockage water level height of the main body shell 2 and is used to detect the blockage water level signal in the main body shell 2, the speaker module 63 and the LED indicator module 64 are both arranged in the second groove 71 and are both connected to the first liquid level sensor module 61 and the second liquid level sensor module 62. Further, the blockage water level height is located 2CM to 5CM above the overflow water level height. Preferably, the first liquid level sensor module 61 and the second liquid level sensor module 62 are both infrared liquid level sensors, and the first liquid level sensor module 61 and the second liquid level sensor module 62 are both embedded in the main body shell 2.

[0040] It should be noted that, in the present embodiment, a first liquid level sensing module is arranged at the overflow water level height in the main body shell, and a second liquid level sensing module is arranged at the blockage water level height in the main body shell. Preferably, the blockage water level height is located 2CM to 5CM above the overflow water level height; when the water level in the main body shell reaches the overflow water level height, the first liquid level sensing module detects the liquid level signal, and prompts the user through the speaker module and the LED indicator module (at this time, the speaker sounds intermittently, and the LED indicator module lights up yellow), that the water level has reached the overflow water level height, so as to remind the user to use water in time and avoid wasting water resources; when the water level in the main body shell reaches the blockage water level height, the second liquid level sensing module detects the liquid level signal, and prompts the user through the speaker module and the LED indicator module (at this time, the speaker sounds continuously, and the LED indicator module lights up red), that the water level has reached the blockage water level height, so as to remind the user that a blockage occurs, so as to avoid further rising of the water level, causing water to overflow from the water holding device and cause trouble to the user.

[0041] In addition, according to the extended function of the adjustable overflow water level height, a liquid level sensor scale can be set in the main body shell, and the liquid level sensor scale is used to measure the water level height in the main body shell; in advance, the user sets a personalized overflow water level height according to the water level height of the water used, and at this time, the floating module is moved to the corresponding overflow water level height by adjusting the first connecting module. At the same time, the corresponding preset overflow water level value and preset blockage water level height value are preset by the liquid level sensor scale. When the liquid level sensor scale detects that the water level has reached the preset overflow water level value, the floating module is moved to the corresponding overflow water level height by adjusting the first connecting module. The speaker module and the LED indicator module prompt the user (the speaker sounds intermittently and the LED indicator module lights up yellow) that the water level has reached the overflow level to remind the user to use water in time and avoid wasting water resources. When the liquid level sensor scale detects that the water level has reached the preset snake water level value, the speaker module and the LED indicator module prompt the user (the speaker sounds continuously and the LED indicator module lights up red) that the water level has reached the blockage level to remind the user that a blockage has occurred and to avoid further rising of the water level, which may cause water to overflow from the water holding device and cause trouble to the user.

[0042] Furthermore, the overflow and drainage device also includes a wireless communication mechanism 10, which is arranged in the second groove 71 and connected to the first liquid level sensor module 61 and the second liquid level sensor module 62. The wireless communication mechanism 10 is a Bluetooth communication mechanism or a WIFI communication mechanism.

[0043] It should be noted that, in this embodiment, the external device (user end such as a mobile phone) is connected to the first liquid level sensor module 61 and the second liquid level sensor module 62 through the wireless communication mechanism, so as to remotely remind the user of the water level change in the body shell, so as to achieve the purpose of timely processing. Preferably, the wireless communication mechanism 10 is a Bluetooth communication mechanism or a WIFI communication mechanism, but is not limited thereto.

[0044] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention.
