Description

Technical Field

[0001] The present invention relates to the field of sanitary ware, in particular to a floor drain. Background Art

[0002] Floor drains are a common drainage device, widely used in bathrooms, kitchens, and other places. During drainage, the water often picks up debris, such as hair and crumbs, which can easily lead to blockages. Therefore, users often need to lift the drain cover to clear the blockage. However, the drain cover is typically flush with the drain base and, in most cases, the floor. This often requires tools to remove the cover, making it inconvenient.

[0003] To address this problem, a new type of floor drain has emerged in the prior art. This type of floor drain features a push-actuated member on the drain cover. By pressing the push-actuated member, one end of the drain cover is lifted by leveraging the principle of leverage and the gravity difference between the two ends of the drain cover, thereby eliminating the need for users to use tools and facilitating removal of the drain cover. However, this new type of floor drain still has the following shortcomings: Its push-actuated member requires not only a first rotating shaft rotatably connected to the drain cover, but also a second rotating shaft rotatably connected to the drain base. Furthermore, the first and second rotating shafts are spaced apart, resulting in a long dimensional tolerance chain and high product precision requirements. Furthermore, a gravity difference is required at both ends of the drain cover, further increasing the complexity of design and manufacturing. Summary of the Invention

[0004] In view of the technical problems existing in the prior art, the present invention provides a floor drain, which shortens the dimensional tolerance chain through structural improvement, making product design and production more concise and efficient.

[0012] In a preferred embodiment, the abutting portion is a rounded corner portion provided on the top of the turntable.

[0013] In a preferred embodiment, the floor drain cover is provided with a limiting portion for limiting the rotation angle of the pressing drive member. The limiting portion is located on the side of the rotating portion close to the pressing portion. When the pressing drive member abuts against the limiting portion, the abutting portion abuts against the floor drain cover.

[0014] In a preferred embodiment, the floor drain cover includes an upper cover provided with a drain hole and a base frame, the base frame is connected to the bottom end of the upper cover and is provided with the guide hole, and the upper cover and / or the base frame are provided with a clearance hole corresponding to the pressing part; the limiting part is provided on the base frame.

[0015] In a preferred embodiment, there are two rotating parts, which are coaxial and opposite to each other; the supporting parts are provided in two groups, which are axially symmetrical, and each group of supporting parts includes two oppositely arranged supporting parts; the two rotating parts correspond one-to-one with the two supporting parts of any group.

DETAILED DESCRIPTION

[0037] In the present invention, the terms "first", "second", etc. are only used to distinguish similar objects, rather than to describe a specific order or sequence, and cannot be understood as indicating or implying relative importance. In the description, the directions or positional relationships indicated by "upper", "lower", "left", "right", "top / bottom", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0038] In addition, in the description of the present invention, "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

[0039] See Figures 1-15 As shown, a floor drain of the present invention comprises a floor drain base 1 and a floor drain cover 2 for draining water. The floor drain cover 2 is removably mounted at a mounting opening 11 provided at the top of the floor drain base 1. The present invention is a strip-shaped floor drain, also known as a linear floor drain. Therefore, the floor drain cover 2 and the floor drain base 1 are both strip-shaped, with the floor drain cover 2 having a first end and a second end in its length direction, respectively.

[0040] The present invention also includes a push-drive member 3, which is rotatably arranged between the floor drain cover 2 and the floor drain seat 1, and the push-drive member 3 and the floor drain cover 2 can move relative to each other in the vertical direction. When the push-drive member 3 is pressed downward, the push-drive member 3 rotates downward relative to the floor drain seat 1, and the push-drive member 3 rotates downward relative to the floor drain cover 2 and moves relative to each other (i.e., the push-drive member 3 moves downward relative to the floor drain cover 2 by a preset angle and a preset displacement, the preset angle being the maximum angle at which the push-drive member 3 rotates downward relative to the floor drain cover 2, and the preset displacement being the maximum distance at which the push-drive member 3 moves downward relative to the floor drain cover 2), driving the first end of the floor drain cover 2 to tilt upward, after which the push-drive member 3 continues to rotate downward relative to the floor drain seat 1 and tilts upward in conjunction with the second end of the floor drain cover 2 by lever principle. The first end and the second end of the floor drain cover 2 are located on both sides of the rotation axis of the push-drive member 3. The position of the push-drive member 3 is located between the first end and the second end of the floor drain cover 2, and is closer to the first end of the floor drain cover 2.

[0041] As a preferred embodiment, the push-drive member 3 includes a rotating portion, and a pressing portion and an abutting portion located on both sides of the rotating portion. The abutting portion abuts against the floor drain cover 2 when the push-drive member rotates downward by a preset angle, so that the push-drive member 3 and the floor drain cover 2 are relatively fixed in the vertical direction and do not undergo relative displacement. The floor drain cover 2 is provided with an elongated guide hole 221 extending in the vertical direction corresponding to the rotating portion. Specifically, the guide hole 221 is a waist-shaped hole, but is not limited thereto. A support portion is provided on the inner side surface of the floor drain seat 1 corresponding to the rotating portion. The rotating portion can be rotatably and slidably engaged with the guide hole 221 and rotatably engaged with the support portion.

[0042] Furthermore, the rotating portion is offset from the middle of the floor drain cover 2 and positioned closer to the first end of the floor drain cover 2. The rotating portion specifically comprises a first portion and a second portion, coaxially arranged. The first portion rotatably and slidably engages with the guide hole 221, while the second portion rotatably engages with the support portion. In this embodiment, the first portion is a rotating shaft, and the second portion is a turntable 31. The following detailed description will use the rotating shaft and turntable 31 as examples. However, it should be noted that this is merely one example of many possible implementations of the first and second portions and does not imply that the configurations of the first and second portions are limited to the rotating shaft and turntable form. The turntable 31 and the rotating shaft are coaxially arranged, with their axes lying horizontally, and the bottom end of the rotating shaft is higher than the bottom end of the turntable 31. Therefore, the rotating shaft rotatably and slidably engages with the guide hole 221, while the turntable 31 rotatably engages with the support portion. Preferably, the rotating shaft comprises a first screw 32, which is threadedly engaged with a threaded hole 312 provided in the turntable 31. This makes the rotating portion easier to manufacture and assemble. Specifically, the first screw 32 includes a threaded section and a cylindrical section without threads. The threaded section is threadedly connected to the threaded hole 312 , and the cylindrical section is rotatably and slidably fitted in the guide hole 221 .

[0043] In this embodiment, the bottom of the turntable 31 is provided with a downwardly convex first arc surface 311. The supporting portion is a support groove 12, the bottom of which is a concave second arc surface 121. The turntable 31 is accommodated in the support groove 12, and its first arc surface 311 and the second arc surface 121 are adapted to and contact each other. The abutment portion is provided on the rotating portion, and the two are integrally formed. Specifically, the abutment portion is a rounded corner portion 35 integrally formed on the top of the turntable 31 to reduce the contact friction between the abutment portion and the floor drain cover 2.

[0044] As a preferred embodiment, the floor drain cover 2 is provided with a limiting portion 222 for limiting the rotation angle of the pressing drive member 3. Specifically, the limiting portion 222 is located on the side of the rotating portion close to the pressing portion. When the pressing drive member 3 rotates downward relative to the floor drain cover 2 until it abuts against the limiting portion 222, the above-mentioned preset angle α is reached. Specifically, when the pressing drive member 3 rotates downward relative to the floor drain cover 2 into position, its pressing portion abuts against the limiting portion 222. When the pressing drive member 3 abuts against the limiting portion 222, the abutting portion (i.e., the rounded portion 35) also abuts against the floor drain cover 2.

[0045] In the present embodiment, there are two rotating parts, which are coaxial and arranged opposite to each other. A connecting part 36 is respectively provided between the pressing part and each rotating part. The pressing part specifically includes a button 33 and a support plate 34, and a connecting part 36 is respectively provided between the support plate 34 and the turntable 31 of each rotating part, and the support plate 34, the connecting part 36, and the turntable 31 are integrally formed. The button 33 is connected to the support plate 34, but is not limited to this. In other embodiments, the button 33 and the support plate 34 are integrally formed. In the present embodiment, the button 33 is connected to the support plate 34 using a second screw 4, but is not limited to this. In other embodiments, the button 33 and the support plate 34 are connected using other connection methods (such as a snap connection, a threaded connection, etc.). Preferably, the button 33 is provided with a mounting portion 331 extending downward, and the support plate 34 is provided with a mounting hole 341 that passes through from top to bottom. The mounting portion 3331 is downwardly inserted into the mounting hole 341 and is threadedly connected to the second screw 4 that passes through the mounting hole upward. Preferably, the cross-sections of the mounting portion 331 and the mounting hole 341 are both non-circular and matched to each other, thereby limiting the rotation of the button 33 relative to the support plate 34. Specifically, the side surfaces of the mounting portion 331 and the side surfaces of the mounting hole 341 are respectively provided with flat portions at corresponding locations.

[0046] The floor drain cover 2 includes an upper cover 21 and a base frame 22. The base frame 22 is connected to the bottom end of the upper cover 21 and is provided with the aforementioned guide hole 221 and stopper 222. The upper cover 21 and / or base frame 22 are provided with a clearance hole 23 corresponding to the pressing portion. Specifically, the upper cover 21 is provided with an elongated drain hole 211 extending along its length. The base frame 22 is welded to the bottom surface of the upper cover 21 and includes a top wall 224 and two side walls 223 disposed oppositely to one side of the top wall 224. The top wall 224 is welded to the bottom surface of the upper cover 21. The top wall 224 and the upper cover 21 are each provided with a clearance hole 23 corresponding to the button 33. The two side walls 223 are each provided with the aforementioned guide hole 221 at one end near the top wall 224. The stopper 222 is provided on the top wall 224 and is located between the two side walls 223. Preferably, the stopper 222 is L-shaped, with the upper end of its vertical portion connected to the top wall 224 and the lower end of its horizontal portion facing the side where the clearance hole 23 is located. The two rotating disks 31 of the two rotating parts are respectively engaged with the opposite outer sides of the two side walls 223 of the base frame 22.

[0047] In this embodiment, the support portions are provided in two groups, the two groups of support portions being axially symmetrical, and each group of support portions includes two support portions (i.e., support grooves 12) disposed opposite each other. The two rotating portions correspond one-to-one with the two support portions of any one group. Therefore, when installing the floor drain cover 2, the two rotating portions on the pressing drive member 3 can be selected to cooperate with any one group of support portions, thereby improving the convenience and flexibility of installing the floor drain cover 2.

[0048] In this embodiment, a mounting platform 111 is provided within the mounting opening 11 of the floor drain base 1. When the floor drain cover 2 is placed within the mounting opening 11, the edges of its upper cover 21 rest against the mounting platform 111, and the top surface of the floor drain cover 3 (i.e., the top surface of the upper cover 21) is flush or substantially flush with the top surface of the floor drain base 1. The upper ends of the support grooves 12 extend through the mounting platform 111. A drain outlet is provided in the center of the bottom of the floor drain base 1, to which the floor drain core 5 is connected.

[0049] A floor drain of the present invention, before the floor drain cover 2 is installed in the floor drain seat 1, the pressing driving member 3 is in an inclined state under the action of its own weight, and its support plate 34 is against the horizontal part of the limiting portion 222, and its first screw 32 is at the bottom of the guide hole 221, as shown in FIG. Figure 5 、 Figure 6 When the drain cover 2 is installed into the installation opening 11 of the drain seat 1, the upper cover 21 contacts the installation platform 111, and the second part of the rotating part (i.e., the turntable 31 in this embodiment) is placed in the support groove 12. The entire pressing drive member 3 is supported by the support groove 12 and rotates in the clockwise direction (the rotation direction is shown in FIG. Figure 8 As shown) rotate to a horizontal state, and move upward relative to the drain cover 2 until the first part of the rotating portion (i.e., the rotating shaft, in this embodiment, the first screw 32) is at the top position of the guide hole 221, as shown Figure 10 、 Figure 11 shown.

[0050] When the floor drain cover 2 needs to be taken out, the button 33 is pressed downwards, and the first arc surface 311 of the turntable 31 and the second arc surface 121 of the support groove 12 rotate frictionally, and the entire pressing drive member 3 rotates downwards in the counterclockwise direction until it hits the limit portion 222. In this process, the first screw 32 should move to the right due to the pressing force, but the first screw 32 cannot move to the right because it is limited by the guide hole 221. Therefore, the first screw 32 can only move downwards relative to the floor drain cover 2, and the turntable 31 cannot move downwards due to the support groove 12. Therefore, the first screw 32 reacts on the guide hole 221, causing the guide hole 221 of the floor drain cover 2 to move upwards, thereby causing the first end of the floor drain cover 2 to tilt upwards, as shown in FIG. Figure 12 、 Figure 13As shown. In this way, there is a certain space between the first end of the floor drain cover 2 and the mounting platform 111, which provides space for the subsequent floor drain cover 2 to rotate using the lever principle to make its second end tilt upward. If the first end of the floor drain cover 2 is not tilted first, the floor drain cover 2 cannot be rotated using the lever principle and its second end cannot be tilted. When the support plate 34 of the pressing drive 3 hits the limiting portion 222, the fillet 35 also hits the floor drain cover 2 to form a fixed line D. Therefore, the floor drain cover 2 and the pressing drive 3 are relatively fixed in the up and down directions without relative displacement. When the button 33 is continuously pressed, the first arc surface 311 of the turntable 31 and the second arc surface 121 of the support groove 12 continue to rotate by friction, so that the pressing drive 3 and the floor drain cover 2 as a whole rotate using the lever principle, and the second end of the floor drain cover 2 is tilted upward, and at the same time, the first end of the floor drain cover 2 is gradually lowered, as shown Figure 14 、 Figure 15 At this time, the user lifts the second end of the floor drain cover 2 to remove the entire floor drain cover 2 and the pressing drive member 3 thereon from the floor drain seat 1. The upward tilting height of the first end of the floor drain cover 2 is smaller than the upward tilting height of the second end of the floor drain cover 2.

[0051] Therefore, the present invention is by improving the driving mechanism of pressing drive member 3 to floor drain cover 2, makes pressing drive member 3 need not be provided with two rotating shafts (i.e. first rotating shaft and second rotating shaft described in background technology) away from each other, and only needs to set above-mentioned rotating shaft portion to cooperate with floor drain cover 2 and floor drain seat 3, although rotating shaft portion comprises above-mentioned first portion and second portion, these two parts are coaxially arranged, therefore, the present invention greatly shortens dimensional tolerance chain, has lower requirements on the production precision of product. In addition, the present invention also need not establish the two ends that make floor drain cover have gravity difference, thereby, makes product design and manufacture more concise and efficient, is conducive to realizing product mass production. A kind of floor drain of the present invention, does not relate to part and is all identical with prior art or can adopt prior art to be realized.

[0052] The above embodiments are only used to further illustrate a floor drain of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the technical solution of the present invention.
