Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary ware, and particularly relates to an overflow ring with a filtering function. Background Art

[0002] In daily life, wash basins, bathtubs and other washing pools are often provided with overflow ports, which are connected to drainage pipes. When the water surface reaches the height of the overflow port, the water is drained to prevent the water from overflowing the pool. The existing overflow port is an open structure. In real life, the overflow pipe will produce odor or harmful gases such as hydrogen sulfide and ammonia due to its tortuous internal structure and relative closure. The odor or harmful gas will flow back into the wash basin through the open overflow port, thus causing health risks to the user. In order to prevent the backflow of odor and harmful gas and ensure the normal function of the overflow port, the applicant has proposed a Chinese utility model patent for an anti-odor structure of a basin overflow port (publication number CN219794097U).

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please check Figures 1 to 3 , an overflow ring with filtering function in a preferred embodiment of the utility model,

[0029] It is detachably mounted on the overflow port (not shown) on the side wall of the wash basin (not shown), and the overflow ring includes two pluggable overflow bodies 10 and a closing valve 20. Specifically, a filter plate 11 is provided at one end of the overflow body 10 facing the wash basin, and a plurality of filter holes 111 are provided on the filter plate 11 at intervals. When the water in the wash basin needs to be discharged into the sewer through the overflow port, dirt, hair, etc. mixed in the water flow will be intercepted and blocked outside the overflow port by the filter plate 11, and the water flow will be discharged into the sewer pipe through the plurality of filter holes 111.

[0030] Furthermore, the closing valve 20 includes a hollow valve body shell 21, a water hole 22 passes through the valve body shell 21 and is connected to the filter hole 111 on the filter plate 11, that is, the water flow in the wash basin can be discharged into the sewer pipe through the filter hole 111 and the water hole 22.

[0031] Furthermore, the overflow body 10 is provided with a first rib 12 protruding from the outer periphery of the ring, and the overflow body 10 can be clamped on the overflow port through the first rib 12, so that the overflow body 10 is stably installed on the overflow port. In addition, the inner wall of the ring of the overflow body 10 is provided with a groove 13, and the outer periphery of the ring of the valve body shell 21 is provided with a second rib 214 protruding from the outer periphery of the ring. When the closing valve 20 is inserted into the overflow body 10, the second rib 214 on the valve body shell 21 can be clamped in the groove 13, so that the closing valve 20 can be stably installed on the overflow body 10.

[0032] Please continue viewing Figure 1 The top of the valve body shell 21 extends downward to form a fixed seat 211, and an axial hole 212 is opened on the fixed seat 211. A cover plate 23 with a rotating shaft 231 can be installed on the fixed seat 211 through the pivotal connection between the axial hole 212 and the rotating shaft 231. In this way, the cover plate 23 can swing in an arc with the rotating shaft 231 as the center under the action of external force. Specifically, in order to prevent people from improperly operating during the installation of the cover plate 23, resulting in incorrect installation of the cover plate 23 and affecting the normal operation function of the cover plate 23, preferably, an installation direction indication arrow is marked on the cover plate 23, such as Figure 1 shown.

[0033] Furthermore, an annular limiting boss 213 is extended radially from the inner wall of the annular valve body shell 21 and along the water hole 22. The cover plate 23 can abut against the limiting boss 213 during the swinging process, that is, when the cover plate 23 leaves the limiting boss 213 and swings upward, the water hole 22 is opened; when the cover plate 23 swings downward, approaches and abuts against the limiting boss 213, the water hole 111 is closed.

[0034] Furthermore, the cover plate 23 can swing between the inner top of the valve body shell 21 and the limiting boss 213. Since the upper end of the limiting boss 213 is close to the filter plate 11 and the lower end thereof is away from the filter plate 11, the limiting boss 213 is inclined relative to the filter plate, thereby making the swing angle of the cover plate 23 less than 90 degrees. Such a design also maximizes the diameter of the water hole 22, thereby ensuring smooth water flow and quickly draining the accumulated water in the wash basin.

[0035] The specific working mode of the preferred embodiment of the utility model is:

[0036] When the tap is turned on, Figure 3 As shown, when the drain outlet at the bottom of the wash basin is blocked, the water in the wash basin will flow into the overflow outlet through the multiple filter holes 111 on the overflow body 10, and the water filtered by the filter holes 111 will flow into the water hole 22 in the valve body shell 21 (see Figure 3The water flows in the direction indicated by the arrow in the middle), and then impacts the cover plate 23 originally resting on the limiting boss 213. At this time, the cover plate 23 gradually moves away from the limiting boss 213 under the impact of the water force, thereby opening the water hole 22, so that the water flows into the sewer pipe through the water hole 22. Figure 2 As shown, after the accumulated water in the wash basin is drained, due to the lack of external impact or support, the cover plate 23 will gradually fall due to its own gravity, and gradually approach and finally abut against the limiting boss 213. At this time, the cover plate 23 closes the water hole 22. Since the cover plate 23 closes the water hole 22, the odor or harmful gas in the sewer pipe is blocked in the sewer pipe by the cover plate 23 and will not flow back into the wash basin through the water hole 22, thereby ensuring that there is no odor or harmful gas from the sewer in the air around the wash basin, ensuring people's health. In the process of the above-mentioned water flow passing through the overflow port, since floating objects such as dirt and hair may be mixed in the water flow, a plurality of filter holes 111 are provided on the filter plate 11 of the overflow body 10 in the preferred embodiment of the utility model. The water flow can be discharged into the sewer pipe through the plurality of filter holes 111, and the filter plate 11 can intercept the floating objects outside the overflow port to prevent these floating objects from further flowing into the water hole 22 in the valve body shell 21, thereby blocking the water hole or winding around the cover plate 23 or the limiting boss 213. In this way, not only the normal swing of the cover plate 23 can be guaranteed, the normal opening and closing of the water hole 22 can be guaranteed, but also the accumulation of dirt in the sewer can be reduced, the sewer blockage can be avoided, and people's living environment can be purified.

[0037] In summary, the overflow ring with filtering function provided by the utility model can not only ensure the normal drainage function of the overflow port, but also filter and intercept the dirt, hair, etc. in the water outside the overflow port when overflowing, prevent clogging of the water hole in the closing valve 20, ensure that the cover plate 23 can open and close the water hole normally, and realize the function of the overflow ring to pass water and prevent odor backflow. Such a design is not only simple in structure and stable in function, but also has strong practicality and low manufacturing cost.
