Technical Field

[0001] This utility model relates to the field of drainer technology, specifically to a drainer for a water basin. Background Technology

[0002] Most kitchen sinks now have a drain outlet at the bottom, and a drain assembly is installed on top of this outlet. The drain assembly connects to a drain pipe, which drains the water from the sink into the sewer. Generally, to prevent large particles from entering the drain pipe and causing blockages, drain assemblies are equipped with filters, sealing caps, and other accessories. As a drainage device, drain assemblies are used in kitchen sinks, bathroom sinks, laundry sinks, and washbasins. Existing drain assemblies are generally classified as pull-out, flap, and pop-up types.

[0003] Pull-up drains are a traditional type of drain, and they have gradually been replaced by flap and pop-up drains in the market. Among them, pop-up drains are widely used in the market due to their simple structure and ease of use. However, during use, pop-up drains are often clogged by micro-particles such as objects, making it difficult to drain water. Moreover, cleaning requires disassembling the entire structure, which is cumbersome. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a drainer for a water basin, so as to facilitate cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a drainer for a water basin, which is installed in the drain pipe of the water basin and partially located inside the water basin, including: a water stop plug body, an upper shell, a spring-loaded component, and a filter screen component; The upper housing is located at the drain outlet of the water basin and has a receiving space for accommodating the filter screen assembly. The filter screen assembly is fitted with the upper housing with a clearance.

The latches have two guide surfaces and a second guide surface with different inclination angles. The first guide surface and the second guide surface are arranged in a figure-eight shape. Two guide surfaces are provided at the positions where the frame of the filter screen outer frame contacts the first guide surface and the second guide surface. The angles of the two guide surfaces correspond to the first guide surface and the second guide surface, respectively.

[0013] In some embodiments, the bottom of the sliding base is further provided with a mounting hole for installing the bouncing component, the bouncing component is threadedly connected to the mounting hole, and the bouncing component includes a spring valve core.

[0014] In some embodiments, the sliding ribs are six in number, and the angle between any two adjacent sliding ribs is the same as the angle between any two adjacent sliding ribs.

[0015] Furthermore, the beneficial effects of this application are as follows: This utility model adds a filter screen assembly, and inside the filter screen assembly is a sliding base that slides with the outer frame of the filter screen to realize the design of a dynamic sliding base. Pulling up the water stop plug will activate the sliding base to carry out the debris inside the filter screen, so that the cleaning process can be achieved without disassembling the whole thing, effectively improving the cleaning efficiency.

[0016] Secondly, the sliding base is equipped with multiple sliding ribs and multiple locking pins, so that the sliding base can be upside down and installed inside the filter screen frame. When not sliding, this effectively improves stability. When sliding, the multiple sliding ribs effectively improve the stability of the sliding. Attached Figure Description

[0020] like Figures 1-9 As shown, this utility model provides a drainer for a water basin, which is installed in the drain pipe of the water basin and partially located inside the water basin, including: a water-stopping plug body 1, an upper shell 5, a spring-loaded component, and a filter screen component; The upper housing 5 is located at the drain outlet of the water basin and has a receiving space for accommodating the filter screen assembly. The filter screen assembly is fitted with the upper housing 5 with a clearance. The water stop plug body 1 is set inside the filter screen assembly through a spring-loaded component and cooperates with the filter screen assembly to seal the gap between the upper housing 5 and the drain outlet. The filter assembly includes a filter frame 4 disposed inside the upper housing 5, and a sliding base 9 slidably disposed on the filter frame 4. The size of the sliding base 9 is the same as the opening size of the filter assembly. The spring component has an unlocking position and a locking position. When the spring component is in the unlocking position, the water stop plug body 1 is disengaged from the filter assembly, and the spring force of the spring component drives the sliding base 9 from the bottom to the top of the filter assembly. In the above structure, a sliding base 9 is provided inside the filter assembly and slidably disposed with the filter frame 4 to realize the design of the dynamic sliding base 9. Pulling up the water stop plug will link the sliding base 9 to carry out the garbage inside the filter, so that the cleaning process can be realized without disassembling the whole assembly, which effectively improves the cleaning efficiency. At the same time, the filter assembly can be completely disassembled, and the garbage can be carried out by one hand, solving the cleaning pain points of traditional structures.

[0021] In one possible implementation, when the spring-loaded component is in the locked position, the water-stop plug body 1 interferes with the filter screen assembly. The spring-loaded component includes a spring valve core 2. The locked position ensures that there is no gap between the water-stop plug body 1 and the filter screen assembly, thus preventing water leakage.

[0022] In one possible implementation, the filter assembly also includes a top cover 3; The inner wall of the filter frame 4 has at least one groove 43 penetrating the inner wall of the filter frame 4. Multiple sliding ribs 91 are provided on the circumference of the sliding base 9 to cooperate with the groove 43. Each sliding rib 91 corresponds to one groove 43. The filter frame 4 also has multiple slots 42. The circumference of the upper cover 3 has multiple buckles 31, each buckle 31 engaging with one slot 42. The upper cover 3 is engaged with the filter frame 4 through the engagement of the buckles 31 and the slots 42. When the jump assembly is in the unlocking position, the upper cover 3 is used to limit the maximum displacement distance of the sliding base 9 on the axis of the filter screen outer frame 4. Multiple locking pins 92 are provided on the side of the sliding base 9 away from the upper cover 3. The locking pins 92 engage with the frame of the filter screen outer frame 4. Each locking pin 92 has two guide surfaces 94 and 95 with different inclination angles, arranged in a V-shape. Two guide surfaces 94 and 95 are provided at the contact points between the frame of the filter screen outer frame 4 and the first guide surface 94 and the second guide surface 95. The two guide surfaces have angles corresponding to the first guide surface 94 and the second guide surface, respectively. The upper cover 3 mainly acts as a baffle to prevent the sliding base 9 from being pulled out when it slides upward. The upper cover 3 is engaged with the filter screen outer frame 4 through the cooperation of the buckle 31 and the slot 42 to achieve a snap-fit ​​connection, which is convenient and quick to install. The specific installation process is as follows: first, install the sliding rib 91 of the sliding base 9 into the corresponding sliding groove 43 of the filter screen outer frame 4, slide it downward to the bottom, until the latch 92 on the back of the sliding base 9 engages with the filter screen. The outer frame 4 is snapped together, and then the buckle 31 of the upper cover 3 is snapped into the corresponding slot 42. It is worth noting that the present invention also provides a sealing ring 11 on the circumferential surface of the upper cover 3, which is mainly used to seal the gap between the upper cover 3 and the water stop plug body 1. At the same time, the pin 92 is provided with a first guide surface 94 and a second guide surface 95 in the shape of the number eight, and a corresponding guide surface is provided at the corresponding position, thereby forming a double guide surface, which effectively reduces the assembly resistance and facilitates the spring valve core 2 to switch back and forth between the unlocking position and the locking position.

[0023] In one possible implementation, the filter screen outer frame 4 is also provided with a plurality of overflow holes 41, wherein the overflow holes 41 are spaced apart between the slide grooves 43, wherein each overflow hole 41 is provided with a filter screen, wherein there is a gap between the filter screen and the upper housing 5, and the filter screen embedded in the overflow hole 41 blocks hair and prevents hair and other impurities from clogging the drain pipe.

[0024] One possible implementation includes a lower housing 8, one end of which is threaded to the upper housing 5, and the other end is provided with a drain pipe. The lower drain pipe can also be connected to a P-bend / S-bend; this invention does not specifically limit its application.

[0025] One possible implementation includes a platform sealing gasket 6, which is annularly disposed on the outside of the upper housing 5 to seal the gap between the upper housing 5 and the drain outlet. It also includes an under-platform sealing gasket 7, which is annularly disposed on the outside of the lower housing 8 to seal the gap between the upper housing 5 and the lower housing 8. Both the platform sealing gasket 6 and the under-platform sealing gasket 7 can be made of rubber. By utilizing the good sealing properties of rubber, the gap between the upper housing 5 and the drain outlet, and the gap between the upper housing 5 and the lower housing 8 are sealed, effectively improving the overall airtightness of the structure.

[0026] In one possible implementation, the bottom of the sliding base 9 is also provided with a mounting hole 93 for installing the spring-loaded component. The spring-loaded component is threadedly connected to the mounting hole 93. It is worth noting that in this utility model, the small end of the spring valve core 2 faces downward. After being installed with the sliding base 9, it will have a larger water passage area, which will result in a larger drainage area. At the same time, the other end of the spring valve core 2 can also be threadedly connected to the water-stop plug body 1. When it is necessary to clean the garbage in the filter screen, hold the water-stop plug body 1 with one hand and pull it upward. The water-stop plug body 1, together with the spring valve core 2 and the sliding base 9, moves upward. The garbage will be pulled out by the sliding base 9, so that it can be manually poured into the garbage can. At this time, when the filter screen sliding base 9 slides to the top of the filter screen outer frame 4, it is convenient to clean the garbage and dirt on the sliding base 9. After cleaning the garbage, push the water-stop plug body 1 downward until the locking pin 92 on the sliding base 9 is engaged with the filter screen outer frame 4, and the installation is completed.

[0027] In one possible implementation, there are six sliding ribs 91, and the angle between any two adjacent sliding ribs 91 is the same as the angle between any two adjacent sliding ribs 91. The sliding base 9 is provided with multiple sliding ribs 91 and multiple locking pins 92, so that the sliding base 9 can be upside down and set inside the filter screen frame 4. When not sliding, the stability is effectively improved. When sliding, the multiple sliding ribs 91 effectively improve the stability of the sliding.

[0028] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
