[0017] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0018] refer to Figure 1-6 In some specific embodiments of the present invention, a floor drain 1000 is provided, including a main body 100, a water flow assembly 200 and a seesaw assembly 300.

[0019] The main body 100 includes a shell 110 and a floor drain core 120, wherein the shell 110 is provided with a mounting port 111, a water passage cavity 112 and a drain port 113 which are connected in sequence, and the floor drain core 120 is connected to the drain port 113. When no water flows through, the floor drain core 120 can block the drain port 113 to prevent odor from overflowing from the floor drain 1000. The water passage cavity 112 is surrounded by the peripheral wall of the shell 110, and one end of the peripheral wall close to the water inlet direction is opened to form the mounting port 111.

[0020] The water flow assembly 200 is arranged in the main body 100 through the installation port 111, so as to realize a detachable connection between the water flow assembly 200 and the shell 110. The water flow assembly 200 includes a limiter 221, a water inlet channel 211 and a water outlet channel 232. The water outlet channel 232 is connected to the drain port 113. Water can enter the water flow assembly 200 from the water inlet channel 211, and flow into the water flow cavity 112 from the water outlet channel 232, and then flow out from the drain port 113 and the floor drain core 120 to complete the drainage process.

[0021] The seesaw assembly 300 is rotatably disposed between the main body 100 and the water overflow assembly 200, with the rotation axis as the boundary. The two ends of the seesaw assembly 300 are respectively a pressing end and a driving end. The user can apply force to the pressing end, so that the driving end is tilted upward, and the driving end is connected to one end of the water overflow assembly 200, so that one end of the water overflow assembly 200 is also tilted, so that the user can take and clean it conveniently. The limiter 221 is located on the movement path of the pressing end. When the pressing end passes over the limiter 221, the user removes the force on the pressing end, and the limiter 221 can block the pressing end so that it cannot be reset, and the water overflow assembly 200 can be driven to tilt.

[0022] According to the floor drain 1000 provided in the embodiment of the present invention, when the user needs to take the water flow component 200 to clean the floor drain 1000, force can be applied to the pressing end to move it beyond the limiter 221 and the driving end can drive the water flow component 200 to tilt up. At this time, even if the user removes the force, the water flow component 200 will always maintain the tilted state. Therefore, the user can perform the above-mentioned taking action with one hand, without having to keep pressing the water flow component 200 with one hand to tilt it up while taking the water flow component 200 with the other hand. The floor drain 1000 provided in the embodiment of the present invention is easy to use and has a better user experience.

[0023] It is worth noting that the floor drain 1000 provided in the embodiment of the present invention can also be used to improve the drainage performance of the floor drain. For example, when the amount of water to be drained is large and it takes a long time to drain water by relying on the water inlet channel 211 on the water flow assembly 200, the user can also drive the water flow assembly 200 to maintain the tilted state through the seesaw assembly 300, so that the water flow can be drained from the water inlet channel 211 and also drained through the channel between the water flow assembly 200 and the main body 100, thereby achieving the effect of improving the drainage efficiency.

[0024] refer to Figure 2 and Figure 6 In some specific embodiments of the present invention, a pressing hole 212 is provided on the water flow component 200, and a pressing platform 340 is provided on the pressing end of the rocker component 300. The shape of the pressing platform 340 is adapted to the pressing hole 212, so that the pressing platform 340 can be set in the pressing hole 212, so that the user can press the pressing end.

[0025] In some specific embodiments of the present invention, the water flow assembly 200 can be positioned and placed by the friction between the side wall of the water flow assembly 200 and the side wall of the installation opening 111, or the side wall of the installation opening 111 is provided with a slope with a small angle, and the water flow assembly 200 is positioned and placed by the friction between the side wall of the water flow assembly 200 and the side wall of the installation opening 111 and the support force of the slope, thereby avoiding the sinking of one end of the water flow assembly 200 due to the heavier weight on the side where the seesaw assembly 300 is located. When pressed, the driving end will be tilted upward, which will make the water flow assembly 200 overcome the friction with the side wall of the installation opening 111 and / or the support force of the installation opening 111, so that one end is tilted and the other end is sunk. When the pressing end passes over the limiting member 221, the user removes the force on the pressing end, and the limiting member 221 can block the pressing end so that it cannot be reset, and because the weight on the side where the seesaw assembly 300 is located is heavier, the state of driving the water flow assembly 200 to tilt can be maintained.

[0026] refer to Figure 2 In some specific embodiments of the present invention, a mounting platform 1111 is further formed on the mounting opening 111. Specifically, the mounting platform 1111 may be concave to form a convex edge, and the water flow assembly 200 may be placed on the mounting platform 1111 to complete the installation. At this time, the end surface of the water flow assembly 200 away from the water flow cavity 112 is flush with the end surface of the main body 100 away from the water flow cavity 112, making the appearance of the floor drain more neat.

[0027] According to the floor drain provided by the embodiment of the present invention, the mounting platform 1111 can be used to place the water flow component 200 to overcome its gravity and avoid falling and tilting. When the pressing end is subjected to force, the driving end drives one end of the water flow component 200 to tilt up, and the other end (i.e., the end close to the pressing end) and the mounting platform 1111 rotate relative to each other, thereby forming a rotation fulcrum of the water flow component 200, and the water flow component 200 rotates around the rotation fulcrum. When the pressing end passes over the limiting member 221, the user removes the force on the pressing end, and the limiting member 221 can block the pressing end so that the rocker component 300 cannot be reset. At this time, the mounting platform 1111 limits the water flow component 200 to prevent the end of the water flow component 200 away from the rotation fulcrum from falling, so that the water flow component 200 maintains the tilted state.

[0028] refer to Figure 4 In some specific embodiments of the present invention, the limiting member 221 is elastically deformable, that is, the limiting member 221 is made of an elastically deformable material, for example, the limiting member 221 may be a plastic or metal spring.

[0029] Furthermore, the position-limiting member 221 includes a connecting portion 2211 and a protruding portion 2212, wherein the connecting portion 2211 is used to connect the position-limiting member 221 to the water-passing assembly 200, and the protruding portion 2212 is arranged on the moving path of the pressing end, so that when the pressing end is forced to move downward, it will first encounter the obstruction of the protruding portion 2212, and since the position-limiting member 221 can be elastically deformed, the protruding portion 2212 will be pushed by the pressing end until the pressing end passes over the protruding portion 2212, and the protruding portion 2212 is reset to the position before the deformation. When the user no longer applies force to the pressing end, the water-passing assembly 200 is reset and drives the pressing end to reset, but due to the obstruction of the protruding portion 2212, the pressing end can only be stuck at the position of the protruding portion 2212 and cannot be completely reset.

[0030] In some specific embodiments of the present invention, a plurality of protrusions 2212 may be provided on the stopper 221 along the moving direction of the pressing end. When the floor drain 1000 is placed in some narrow spaces, the user may control the magnitude of the pressing force and the time of applying the force so that the pressing end stops after passing only the first protrusion 2212, thereby maintaining the water flow component 200 at a relatively small tilting height, and avoiding the water flow component 200 being unable to maintain a tilted state due to space limitations. When the floor drain 1000 has a spacious space, the pressing end may stop after passing over a plurality of protrusions 2212, so that the water flow component 200 can be maintained at a relatively high tilting height, making it easier for the user to pick it up.

[0031] It is understandable that the plurality of protrusions 2212 can be selected to maintain different tilting heights for the water drain assembly 200, thereby making the size of the channel between the water drain assembly 200 and the main body 100 different and the drainage volume different. When the tilting height is large, the drainage volume is large, and vice versa, the drainage volume is small. The user can freely select the tilting height of the water drain assembly 200 according to the drainage requirements, further improving the practicality of the floor drain 1000.

[0032] refer to Figure 2 and Figure 6 In some specific embodiments of the present invention, two first shaft grooves 114 are symmetrically arranged on the side wall of the main body 100. The first shaft grooves 114 can be arranged at different heights and can be arranged on the installation opening 111 or on the side wall of the water passage chamber 112. A rotating shaft 310 is arranged on the seesaw assembly 300. The rotating shaft 310 is rotatably installed in the first shaft groove 114. The seesaw assembly 300 rotates with the rotating shaft 310 as the rotation axis.

[0033] refer to Figure 3 In some specific embodiments of the present invention, the water drain assembly 200 includes a grate 210 assembly and a filter 230, the water inlet channel 211 is provided on the grate 210 assembly, and the water outlet channel 232 is provided on the filter 230. It can be understood that the water inlet channel 211 can be a through hole penetrating the grate 210 assembly, the filter 230 is a filter screen, which is used to block the hair and other garbage flowing through the floor drain 1000 during the drainage process to avoid blockage, and the water outlet channel 232 is the mesh on the filter screen.

[0034] Therefore, when the garbage on the filter screen accumulates to a certain extent, the user needs to remove it for cleaning to avoid clogging. At this time, the user only needs to tilt the water flow component 200 through the seesaw component 300 to conveniently remove the water flow component 200 and clean the filter screen therein.

[0035] refer to Figure 6 and Figure 7 In some specific embodiments of the present invention, the seesaw assembly 300 is provided with a first avoidance opening 320, which is a notch on the seesaw assembly 300 that opens toward the filter element 230, that is, the seesaw assembly 300 is roughly C-shaped. When the seesaw assembly 300 is pressed and rotated, the filter element 230 can be avoided to avoid interference between the two and prevent them from being unable to rotate.

[0036] refer to Figure 2 , Figure 3 , Figure 8 and Fig. 9In some specific embodiments of the present invention, the grate assembly and the filter element 230 may be integrally formed, or the connection between the two may be realized through a connecting assembly. Specifically, one of the grate assembly and the filter element 230 is provided with a mounting groove 222, and the other is provided with a mounting post 231, and the mounting post 231 can be slidably inserted into the mounting groove 222 to realize a detachable connection between the grate assembly and the filter element 230. Therefore, when the user needs to clean the filter element 230, the water flow assembly 200 can be lifted up and removed by the rocker assembly 300, and then the grate assembly and the filter element 230 can be disassembled, so as to better clean the filter element 230.

[0037] Specifically, the installation groove 222 is set on the grate assembly and the installation column 231 is set on the filter element 230 as an example: the installation groove 222 is roughly inverted L-shaped, and the installation groove 222 is divided into a vertical section and a horizontal section with an opening. The opening of the vertical section faces the filter element 230, and the installation column 231 on the filter element 230 can slide into the installation groove 222 through the opening of the vertical section, and then slide horizontally into the horizontal section when sliding to the horizontal section, thereby completing the connection.

[0038] refer to Figure 6 In some specific embodiments of the present invention, a second avoidance opening 330 is provided on the side wall of the first avoidance opening 320. When the water-passing assembly 200 is connected to the rocker assembly 300, the protruding mounting post 231 in the first avoidance opening 320 will interfere with the rocker assembly 300. The position of the second avoidance opening 330 corresponds to the position of the mounting post 231 in the first avoidance opening 320, thereby avoiding the occurrence of interference.

[0039] It is understandable that the escape space of the second escape opening 330 is larger than the volume of the mounting column 231 , so that sufficient escape space can be provided during the rotation of the rocker assembly 300 .

[0040] refer to Figure 2 and Figure 8 In some specific embodiments of the present invention, the grate assembly includes a grate 210 and a connector 220. The grate 210 and the connector 220 may be integrally formed or connected by bonding, buckling, etc. Specifically, the connector 220 is disposed on a side of the grate assembly close to the filter element 230, and one of the mounting groove 222 and the mounting column 231 is disposed on the connector 220, while the other is disposed on the filter element 230. The limiting member 221 is disposed on a side of the connector 220 close to the first avoidance opening 320. Thus, when the rocker assembly 300 is pressed and rotated, the inner wall of the first avoidance opening 320 may cooperate with the limiting member 221 to limit the reset of the rocker assembly 300.

[0041] refer to Figure 2 , Figure 6 and Figure 8 In some specific embodiments of the present invention, the floor drain 1000 also includes a pin shaft 400, and a second shaft groove 350 is arranged on the driving end. Specifically, the second shaft groove 350 is arranged on both sides of the opening of the first avoidance opening 320, and a third shaft groove 223 is arranged on the water overflow component 200, and the third shaft groove 223 is specifically arranged on the connecting member 220. The second shaft groove 350 and the third shaft groove 223 are arranged correspondingly. By simultaneously penetrating the second shaft groove 350 and the third shaft groove 223 by the pin shaft 400, the rotational connection between the seesaw component 300 and the water overflow component 200 can be realized, so that when the seesaw component 300 is pressed and rotated, the driving end and the water overflow component 200 can be rotated relative to each other, and the water overflow component 200 can be driven to tilt up.

[0042] Through the above embodiment, the seesaw assembly 300 and the water-passing assembly 200 can be rotatably connected, making the process of driving the water-passing assembly 200 to tilt smoother. At the same time, it is prevented that the driving end and the water-passing assembly 200 are relatively displaced during this process, which makes the driving function of the seesaw assembly 300 invalid.

[0043] refer to Figure 2 and Figure 6 In some embodiments of the present invention, the floor drain 1000 also includes a torsion spring 500, which is connected to the pin 400, and one end of the torsion spring 500 is against the seesaw assembly 300, and the other end is against the water overflow assembly 200. Therefore, when the user applies force to the pressing end to rotate the seesaw assembly 300, it is necessary to overcome the elastic force of the torsion spring 500, so that a certain tactile feedback can be provided to the user, and the side of the torsion spring 500 close to the driving end can provide a tilting support force for the water overflow assembly 200. At the same time, when the pressing end is driven to pass over the limit member 221 during the resetting process, the elastic force of the torsion spring 500 provides a resetting force for the resetting process, so that the seesaw assembly 300 can be reset faster. Therefore, when the water overflow assembly 200 needs to be reset, it is only necessary to push the side of the pressing end close to the water overflow chamber 112 so that it passes over the limit member 221, and then the water overflow assembly 200 can continue to complete the reset.

[0044] Furthermore, a limiting groove 360 ​​is provided on one side of the seesaw assembly 300 close to the torsion spring 500, and the torsion spring 500 abutting against the seesaw assembly 300 can be positioned in the limiting groove 360, thereby preventing the torsion spring 500 from sliding along the abutting surface, causing the reset function of the torsion spring 500 to fail.
