Benefits of technology

[0003] It is therefore a primary object of the present invention to provide a bugproof and odorproof sealing ring structure of a sinkhole screen. The sealing ring structure has a disc-shaped diaphragm instead of the conventional valve-type gum ring. The diaphragm can truly achieve a bugproof and odorproof effect.
[0008] After assembled, the sealing ring is directly placed on a shoulder section of the conventional sinkhole screen to achieve a bugproof and odorproof effect.

Problems solved by technology

Therefore, after a period of use, the resilient plastic valves of the gum ring tend to elastically fail and deform and become suspend from the circumference of the gum ring.
Under such circumstance, the valves can no more shade the sinkhole and the gum ring will lose its bugproof and odorproof function.

Embodiment Construction

[0017] Please refer to FIG. 1. The sealing ring structure of the sinkhole screen of the present invention includes a base seat 10, a diaphragm 20 and a gum ring 30. Referring to FIGS. 2 to 5, the base seat 10 is a substantially ring-shaped body integrally made of metal or plastic material. The central portion of the base seat 10 is formed with a screen section 11 having multiple perforations 12. The center and the circumference of the screen section 11 are respectively formed with holders 13, 14. The upper end of the base seat 1 is formed with a flange 15. The lower end of the base seat 1 is formed with a skirt 16. The flange 15 can be a stepped flange having a step 151. The skirt 16 can be a stepped skirt having a step 161. A lift ring 17 is disposed on the base seat 10 for lifting the sealing ring.

[0018] The diaphragm 20 is substantially a thin disc integrally made of elastic and weatherproof rubber or semisoft plastic material. The diaphragm 20 has chucking bosses 21, 22 respect...

Abstract

A bugproof and odorproof sealing ring structure of a sinkhole screen, including a base seat, a diaphragm and a gum ring. The base is a ring body having a screen section formed with multiple perforations and holders. An upper end and a lower end of the base seat are respectively formed with a stepped flange and a stepped skirt. The diaphragm is a gum-made thin disc having chucking bosses inserted in the holders to connect the diaphragm under the base seat with outer circumference of the diaphragm tightly attaching to the stepped skirt of the base seat. The inner circumference of the gum ring is formed with a stepped annular groove adapted to the stepped flange of the base seat, whereby the gum ring can be snugly fitted around the stepped flange of the base seat. The sealing ring can be directly placed on a conventional sinkhole screen to achieve a bugproof and odorproof effect.

Description

BACKGROUND OF THE INVENTION [0001] The present invention is related to a bugproof and odorproof sealing ring structure of a sinkhole screen, and more particularly to a sealing ring which can be inlaid in a conventional sinkhole screen to achieve a bugproof and odorproof effect. [0002] Taiwanese Patent Publication No. 284567 discloses a valve-type bathroom sinkhole screen structure. Such resilient plastic valve-type sinkhole screen substantially can achieve a bugproof and odorproof effect. Such sinkhole screen structure includes a sinkhole cover and a resilient gum ring having multiple radially arranged acute triangular resilient valves. The gum ring is placed on a shoulder section of the sinkhole screen to isolate the sink from the bugs and stink in the draining pipe. However, it is known that pans, cookers, bowls and dishes are frequently washed in the sink with cold or hot water. Therefore, after a period of use, the resilient plastic valves of the gum ring tend to elastically fai...
