Description
Technical Field
[0001] This utility model relates to the technical field of drainers, and in particular to a drain switch for a spring-loaded drainer. Background Technology
[0002] In bathtubs, sinks, or kitchen basins, a pop-up drain is typically installed at the bottom for convenient water storage and drainage. By controlling the drain's on / off switch, water storage and drainage are achieved. Currently, most pop-up drains on the market feature a vertical push-button that extends upwards through the center of the filter basket. While this design is easy to use when switching between modes, the push-button creates a ring-shaped internal space for the filter basket. Furthermore, the push-button position on the drain, with the entire filter basket located within the drain outlet, further compresses the basket's volume, leading to easy accumulation of debris and blockages at the drain outlet. This makes cleaning difficult and results in slow drainage. This design also fails to meet users' design requirements for drain outlets of different sizes and shapes. Secondly, the reduced space in the drain basket makes it easy for waste to fill up during drainage. Users need to collect and remove the overflowing waste or empty some of the waste from the basket before sweeping it back in, and then remove the basket to empty the waste. Clearly, the smaller space and annular interior make it easy for waste to get stuck, making it difficult to empty or remove, and cleaning the drain basket is inconvenient. Therefore, this invention provides a new type of pop-up drain switch to solve the above-mentioned technical problems. Utility Model Content
[0003] The purpose of this invention is to provide a drain switch for a pop-up drain that does not cause blockages and is easy to clean.
[0004] The purpose of this utility model is achieved as follows: A drain switch for a pop-up drain includes a switch body, a spring, an inner fixing ring, and an outer fixing ring. The switch body slides vertically within the inner fixing ring, and the outer fixing ring is fitted onto the outer surface of the inner fixing ring. The spring is located within the switch body. The switch body includes a top cover and a base, which are fixedly connected as a single unit. The upper and lower ends of the spring abut against the top cover and the inner fixing ring, respectively. This drain switch is used to control the opening and closing of the drain outlet when the drain is pressed. After each press, the spring drives the switch body to rise and reset for the next press. Because the drain switch is external to the pop-up drain and the drain outlet, it does not occupy the space of the drain outlet. Therefore, the drainage space is large, preventing residue from accumulating on the filter screen and causing blockages, resulting in faster drainage. Compared to the push-button mechanism of existing pop-up drainers, the drain switch of this invention is located outside the drain outlet and the pop-up drainer. Therefore, the drain switch does not occupy the space of the drain outlet, avoiding excessive occupation of the drain outlet space and preventing the drain outlet space from shrinking. The drain outlet is not easily blocked, which provides convenience for users to clean. In addition, the space inside the filter tank is well open, and garbage is not easily stuck.
[0005] The present invention can be further improved in the following ways.
[0006] The inner fixing ring is equipped with a limiting ring, which is coaxially arranged with the inner fixing ring. There is a gap between the outer wall of the limiting ring and the inner wall of the inner fixing ring to form a guide hole. The outer wall of the limiting ring and the inner wall of the inner fixing ring are fixedly connected by a limiting connecting block.
[0007] The inner wall of the limiting ring is provided with a boss, and the lower end of the compression spring abuts against the boss, thereby supporting the compression spring and the switch body is lifted and reset by the compression spring.
[0008] The outer wall of the inner fixing ring is fastened to the outer fixing ring, and there is a clamping gap between the outer wall of the inner fixing ring and the upper end of the outer fixing ring. The clamping gap is used to clamp the filter screen, thereby realizing the fixing of this utility model on the filter screen.
[0009] The switch body is shaped like an I-beam, with an inner fixing ring fitted in the middle of the switch body. The structure of this utility model is reasonably designed, with large areas at the top and bottom of the switch body, making it convenient for users to press the switch body and press down the drain.
[0010] The upper cover has a connecting screw hole post inside, and the base has a connecting post with a connecting screw rod. The connecting screw rod passes upward through the limiting ring and is threadedly connected to the connecting screw hole post. The lower end of the upper cover abuts against the base. The connecting post and connecting screw rod are located inside the upper cover. The compression spring is sleeved on the connecting screw hole post and the connecting post, thereby assembling the upper cover and the base into one piece. The compression spring is located inside the switch body and can also reset the switch body.
[0011] The outer side wall of the top cover is provided with a limiting elongated hole along its length, and the limiting connecting block is located inside the limiting elongated hole, and the limiting connecting block and the limiting elongated hole are matched for limiting.
[0012] The diameter of the base and the top cover are larger than the diameter of the inner fixing ring.
[0013] This utility model also includes a filter screen with a through hole in the center. An inner fixing ring is installed on the through hole, and the outer wall of the inner fixing ring and the upper end of the outer fixing ring clamp the filter screen together. The structure of this utility model is reasonably designed. The drain switch is fixed to the filter screen, and the drain switch can also serve as a handle for the filter screen, facilitating installation and removal. The filter screen is located above the drain outlet, and its diameter can be designed to be larger than the diameter of the drain outlet. Therefore, the filter screen can hold a larger volume and area of residue, making it less likely for residue to clog the drain outlet, thus making cleaning very convenient and increasing drainage speed.
[0014] The beneficial effects of this utility model are as follows: 1. Compared with the push-button of the existing pop-up drain, the drain switch of this utility model is located outside the drain outlet and the pop-up drain. Therefore, the drain switch will not occupy the space of the drain outlet, avoid the excessive occupation of the drain outlet space, avoid the shrinkage of the drain outlet space, and the drain outlet is not easy to be blocked, which provides convenience for users to clean. In addition, the space inside the filter tank is well open, and garbage is not easy to get stuck.
[0015] 2. In addition, the filter screen of this utility model is located on the drain switch, which is also above the drain outlet. The diameter of the filter screen of this utility model can be designed to be larger than the diameter of the drain outlet. Therefore, the filter screen can hold a larger volume and area of residue, and the residue is not easy to block the drain outlet, making cleaning very convenient. Attached Figure Description

[0027] Example 1, as Figures 1 to 11 As shown, a drain switch for a spring-loaded drain includes a switch body 7, a spring 3, an inner fixing ring 2, an outer fixing ring 4, and a filter screen 8. The switch body 7 is slidably disposed within the inner fixing ring 2, and the outer fixing ring 4 is sleeved on the outer side of the inner fixing ring 2. The spring 3 is disposed within the switch body 7. The switch body 7 includes an upper cover 1 and a base 6. The upper cover 1 and the base 6 are fixedly connected as a whole. The upper end and the lower end of the spring 3 abut against the upper cover 1 and the inner fixing ring 2, respectively.
[0028] This is a more specific technical solution of the present invention.
[0029] The inner fixing ring 2 is provided with a limiting ring 21. The limiting ring 21 is coaxially arranged with the inner fixing ring 2. There is a gap between the outer side wall of the limiting ring 21 and the inner side wall of the inner fixing ring 2 to form a guide hole 22. The outer side wall of the limiting ring 21 and the inner side wall of the inner fixing ring 2 are fixedly connected by a limiting connecting block 23. The limiting connecting block 23 is located in the limiting elongated hole 12, and the limiting connecting block 23 and the limiting elongated hole 12 are limited and engaged.
[0030] The inner wall of the limiting ring 21 is provided with a boss 24, and the lower end of the compression spring 3 abuts against the boss 24.
[0031] The outer wall of the inner fixing ring 2 is fastened to the outer fixing ring 4, and there is a clamping gap between the outer wall of the inner fixing ring 2 and the upper end of the outer fixing ring 4.
[0032] The switch body 7 is shaped like an I-beam, and the inner fixing ring 2 is fitted in the middle of the switch body 7.
[0033] The upper cover 1 has a connecting screw hole post 11 inside, and the base 6 has a connecting post 61. The connecting post 61 has a connecting screw 5. The connecting screw 5 passes upward through the limiting ring 21 and is threadedly connected to the connecting screw hole post 11. The lower end of the upper cover 1 abuts against the base 6. The connecting post 61 and the connecting screw 5 are inside the upper cover 1. The compression spring 3 is sleeved on the outside of the connecting screw hole post 11 and the connecting post 61.

[0035] The diameter of the base 6 and the top cover 1 are larger than the diameter of the inner fixing ring 2.
[0036] The filter screen 8 has a through hole 81 in the center, and the inner fixing ring 2 is installed on the through hole 81. The outer side wall of the inner fixing ring 2 and the upper end of the outer fixing ring 4 clamp the filter screen 8.
[0037] The working principle of this utility model is as follows: The user first installs the pop-up drain into the drain outlet of the sink. At this point, the sealing ring of the pop-up drain keeps the drain outlet sealed. Then, the user installs the filter screen 8 and drain switch together on top of the drain outlet. The drain switch is now positioned directly above the pressure rod of the pop-up drain. When the user presses down on the switch body 7, it descends and presses down on the pressure rod of the pop-up drain, compressing the spring 3. The sealing ring of the pop-up drain rises and disengages from the drain outlet, allowing water in the sink to drain away. Residue in the sink is filtered by the filter screen and will not clog the drain outlet. After the user releases the switch body 7, it rises back to its original position under the elastic force of the spring 3.
[0038] When the user presses down the lever of the switch body 7 again, the switch body 7 descends and presses down the pop-up drain. The sealing ring of the pop-up drain descends and keeps the drain outlet sealed, thus enabling the water tank to store water.
[0039] The bouncing drain device described in this utility model is existing technology, and its working principle and structure will not be described in detail here.
