[0002] As a drainage device, floor drains are widely used in bathrooms, kitchens and other kitchen and bathroom scenarios. Since hair, debris and other debris are often mixed in the water flow during the drainage process in the above scenarios, it is easy to cause the floor drain to be blocked, reduce the drainage flow of the floor drain, or even cause complete blockage. Therefore, users often need to remove or lift the floor drain cover to deal with the blockage. However, the floor drain cover is usually flush with the floor drain shell, and is generally flush with the ground. Users often need to press from one side of the floor drain cover to lift the other side in order to grab the floor drain cover. When cleaning, the user needs to press the floor drain cover continuously with one hand to keep the other side in a tilted state so that the other hand can grab the floor drain cover. Otherwise, once the pressing hand is released, the floor drain cover will be reset to a flush state. Therefore, the user must use two hands to operate simultaneously during the cleaning process, which is very inconvenient to use. Summary of the Invention

[0036] The following describes in detail embodiments of the present invention, 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 explain the present invention, and should not be construed as limiting the present invention.

[0037] 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 rocker assembly 300.

[0038] The main body 100 includes a housing 110 and a floor drain core 120. The housing 110 is provided with a mounting opening 111, a water passage cavity 112, and a drain outlet 113, which are sequentially connected. The floor drain core 120 is connected to the drain outlet 113. When no water is flowing through, the floor drain core 120 can block the drain outlet 113 to prevent odor from escaping from the floor drain 1000. The water passage cavity 112 is enclosed by the peripheral wall of the housing 110, and one end of the peripheral wall, close to the water inlet direction, is open to form the mounting opening 111.

[0039] 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.

[0040] The seesaw assembly 300 is rotatably disposed between the main body 100 and the water overflow assembly 200, with the axis of rotation serving as the dividing line. The two ends of the seesaw assembly 300 are a pressing end and a driving end, respectively. The user can apply force to the pressing end, causing the driving end to tilt upward. The driving end then connects to one end of the water overflow assembly 200, thereby also tilting the other end of the water overflow assembly 200, making it easier for the user to remove and clean the device. A stopper 221 is located along the movement path of the pressing end. Once the pressing end passes the stopper 221 and the user removes the force on the pressing end, the stopper 221 blocks the pressing end from returning to its original position, thereby maintaining the tilted state of the water overflow assembly 200.

[0041] According to the floor drain 1000 provided by the embodiment of the present invention, when a user needs to remove the water drain assembly 200 for cleaning, they can apply force to the pressing end to move it past the limiter 221 and cause the driving end to drive the water drain assembly 200 to tilt upward. At this point, even if the user removes the force, the water drain assembly 200 remains tilted. Therefore, the user can perform the above-mentioned removal action with one hand, without having to press the water drain assembly 200 with one hand while the other hand removes the water drain assembly 200. The floor drain 1000 provided by the embodiment of the present invention is convenient to use and provides a better user experience.

[0042] 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 draining through the water inlet channel 211 on the water flow assembly 200 would take a long time, the user can also use the seesaw assembly 300 to drive the water flow assembly 200 to maintain the tilted state, so that the water flow can be drained not only from the water inlet channel 211 but also through the channel between the water flow assembly 200 and the main body 100, thereby achieving the effect of improving drainage efficiency.

[0043] 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.

[0044] In some specific embodiments of the present invention, the water flow assembly 200 can be positioned and placed by the friction between the side walls of the water flow assembly 200 and the side walls of the installation opening 111, or a slope with a smaller angle is provided on the side walls of the installation opening 111, and the water flow assembly 200 is positioned and placed by the friction between the side walls of the water flow assembly 200 and the side walls of the installation opening 111 and the supporting force of the slope, thereby avoiding the sinking of one end of the water flow assembly 200 due to the greater weight of the side where the rocker assembly 300 is located. When pressed, the driving end will tilt upward, causing the water overflow component 200 to overcome the friction with the side wall of the mounting port 111 and / or the supporting force of the mounting port 111, so that one end will tilt and the other end will sink. 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. Moreover, since the weight on the side where the rocker assembly 300 is located is greater, the state of driving the water overflow component 200 to tilt can be maintained.

[0045] refer to Figure 2In some specific embodiments of the present invention, a mounting platform 1111 is further formed on the mounting opening 111. Specifically, the mounting platform 1111 can be concave to form a convex edge, and the water flow assembly 200 can 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.

[0046] 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 assembly 200 to overcome its gravity and prevent it from falling or tilting. When the pressing end is subjected to force, the driving end drives one end of the water flow assembly 200 to tilt up, and the other end (i.e., the end closer to the pressing end) and the mounting platform 1111 rotate relative to each other, thereby forming a rotation fulcrum for the water flow assembly 200, around which the water flow assembly 200 rotates. 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, preventing the rocker assembly 300 from resetting. At this time, the mounting platform 1111 limits the water flow assembly 200, preventing the end of the water flow assembly 200 away from the rotation fulcrum from falling, thereby maintaining the water flow assembly 200 in the tilted state.

[0047] 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 can be a plastic or metal spring.

[0048] Furthermore, the stopper 221 includes a connecting portion 2211 and a raised portion 2212, wherein the connecting portion 2211 is used to connect the stopper 221 to the water flow assembly 200, and the raised portion 2212 is arranged in the movement path of the pressing end. Therefore, when the pressing end is forced to move downward, it will first encounter the obstruction of the raised portion 2212. Because the stopper 221 is elastically deformable, the raised portion 2212 is pushed by the pressing end until the pressing end passes the raised portion 2212, at which point the raised portion 2212 returns to its pre-deformation position. When the user no longer applies force to the pressing end, the water flow assembly 200 returns to its original position and drives the pressing end to return to its original position. However, due to the obstruction of the raised portion 2212, the pressing end can only be stuck in the position of the raised portion 2212 and cannot be fully restored.

[0049] In some specific embodiments of the present invention, the stopper 221 may be provided with multiple protrusions 2212 along the direction of movement of the pressing end. When the floor drain 1000 is located in a narrow space, the user can control the amount of force and duration of the pressing so that the pressing end stops after passing the first protrusion 2212, thereby maintaining the water drain assembly 200 at a relatively low tilt height and preventing the water drain assembly 200 from being unable to maintain its tilted state due to space limitations. If the floor drain 1000 is located in a spacious space, the pressing end can be stopped after passing multiple protrusions 2212, maintaining the water drain assembly 200 at a relatively high tilt height, making it easier for the user to pick up the floor drain 1000.

[0050] It is understood that the multiple raised portions 2212 allow the drain assembly 200 to be maintained at different tilt heights, thereby varying the size of the passage between the drain assembly 200 and the main body 100 and the drainage volume. A larger tilt height results in a greater drainage volume, while a lower tilt height results in a smaller drainage volume. Users can freely select the tilt height of the drain assembly 200 based on their drainage needs, further improving the practicality of the floor drain 1000.

[0051] refer to Figure 2 and Figure 6 In some specific embodiments of the present invention, two first shaft grooves 114 are symmetrically provided on the sidewall of the main body 100. The first shaft grooves 114 can be provided at different heights and can be provided on the mounting opening 111 or on the sidewall of the water passage chamber 112. The rocker assembly 300 is provided with a rotating shaft 310, which is rotatably mounted in the first shaft groove 114. The rocker assembly 300 rotates around the rotating shaft 310.

[0052] 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 element 230. The water inlet channel 211 is provided on the grate 210 assembly, and the water outlet channel 232 is provided on the filter element 230. It is understood that the water inlet channel 211 can be a through hole that passes through the grate 210 assembly, and the filter element 230 is a filter screen used to block hair and other debris from flowing through the floor drain 1000 during drainage to prevent blockage. The water outlet channel 232 is the mesh on the filter screen.

[0053] Therefore, when the garbage on the filter 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 assembly 200 through the seesaw assembly 300 to conveniently remove the water flow assembly 200 and clean the filter therein.

[0054] refer to Figure 6 and Figure 7In some specific embodiments of the present invention, the rocker assembly 300 is provided with a first avoidance opening 320, which is a notch on the rocker assembly 300 that opens toward the filter element 230, that is, the rocker assembly 300 is roughly C-shaped. When the rocker assembly 300 is pressed and rotated, it can avoid the filter element 230 to prevent interference between the two and prevent rotation.

[0055] refer to Figure 2 、 Figure 3 、 Figure 8 and Figure 9 In some specific embodiments of the present invention, the grate assembly and the filter element 230 can be integrally formed, or they can be connected via 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. The mounting post 231 can slide into the mounting groove 222 to achieve a detachable connection between the grate assembly and the filter element 230. Therefore, when the user needs to clean the filter element 230, they can first use the rocker assembly 300 to tilt the water filter assembly 200 and then remove it. Then, the grate assembly and the filter element 230 can be disassembled, thereby better cleaning the filter element 230.

[0056] Specifically, the installation groove 222 is set on the grating assembly and the installation column 231 is set on the filter element 230 as an example: the installation groove 222 is roughly in an inverted L shape, and the installation groove 222 is divided into a vertical section with an opening and a horizontal section. The opening of the vertical section faces the filter element 230. The installation column 231 on the filter element 230 can slide into the installation groove 222 through the opening of the vertical section, and when it slides to the horizontal section, it slides horizontally into the horizontal section to complete the connection.

[0057] 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 flow assembly 200 is connected to the rocker assembly 300, the protruding mounting post 231 located 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 located in the first avoidance opening 320, thereby avoiding the occurrence of interference.

[0058] It is understandable that the escape space of the second escape opening 330 is larger than the volume of the mounting post 231 , so that sufficient escape space can be provided during the rotation of the rocker assembly 300 .

[0059] refer to Figure 2 and Figure 8In 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 can be integrally formed or connected by bonding, snapping, etc. Specifically, the connector 220 is arranged 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 arranged on the connector 220, and the other is arranged on the filter element 230. The limiting member 221 is arranged on a side of the connector 220 close to the first avoidance opening 320. Therefore, when the rocker assembly 300 is pressed and rotated, the inner wall of the first avoidance opening 320 can cooperate with the limiting member 221 to limit the reset of the rocker assembly 300.

[0060] 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 provided 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 provided on the water flow component 200. The third shaft groove 223 is specifically arranged on the connecting member 220, and 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 through the pin shaft 400, the rotational connection between the rocker component 300 and the water flow component 200 can be realized. When the rocker component 300 is pressed and rotated, the driving end and the water flow component 200 can be driven to tilt while relatively rotating.

[0061] Through the above embodiment, the seesaw assembly 300 and the water overflow assembly 200 can be rotatably connected, making the process of driving the water overflow assembly 200 to tilt smoother. At the same time, relative displacement between the driving end and the water overflow assembly 200 is avoided during this process, which would cause the driving function of the seesaw assembly 300 to fail.

[0062] refer to Figure 2 and Figure 6When the user applies force to the pressing end to rotate the rocker assembly 300, the elastic force of the torsion spring 500 needs to be overcome, thereby providing a certain tactile feedback for the user. In addition, the side of the torsion spring 500 close to the driving end can provide a tilting support force for the water flow 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 rocker assembly 300 can be reset faster. Therefore, when the water flow assembly 200 needs to be reset, it is only necessary to push the side of the pressing end close to the water flow chamber 112 so that it passes over the limit member 221, and the water flow assembly 200 can continue to complete the reset.

[0063] Furthermore, a limiting groove 360 ​​is provided on the side of the rocker assembly 300 close to the torsion spring 500, and the torsion spring 500 that presses against the rocker assembly 300 can be positioned in the limiting groove 360, thereby preventing the torsion spring 500 from sliding along the pressing surface, causing the reset function of the torsion spring 500 to fail.
