Description

Insect and odor-resistant water head structure

This creation system relates to a structure of a falling head installed at the inlet end of a drain pipe, especially for blocking the inclusion of debris into the drain pipe to cause blockage, and preventing pests or odors in the drain pipe from invading the room and preventing insects and odors. Falling water head.

According to the general bathroom and kitchen floor, there is a drain pipe for the waste water to flow out, and a drop head is fixed at the joint between the drain pipe and the ground to prevent the debris from entering the drain pipe and causing blockage. The traditional falling head structure is provided with a filter hole to block debris from entering the drain pipe. However, the filter hole is in a fixed open state, thereby causing a long-term accumulated foul smell in the drain pipe, which will follow the drain pipe and be scattered by the filter hole. To the indoors, at the same time, various mosquitoes and cockroaches in the drain pipe can easily enter the room from the falling head, which causes the indoor environmental quality to be seriously affected. It is created by the falling head structure with anti-insect and deodorizing functions.

For example, the new patent No. M448515 “Deodorant and Insect-Reducing Head Structure” is a conventional insect-proof and odor-resistant water head structure. The blocker is locked with a bolt at the flow port and a spring is placed at the bolt. The baffle is pierced by the bolt, so that one end of the spring abuts against the baffle to form a closing of the flow port to achieve a deodorant and insect proof effect.

However, in the conventional insect-proof and odor-resistant water head structure, in order to lock the bolt at the circulation port, a plurality of drainage holes are formed by punching at the circulation port, and the drainage holes are formed between the drainage holes. The plurality of ribs of the spurs are provided with a screw hole or a perforation at the center of the plurality of ribs for bolting or threading. However, such a structure may cause hair and dirt to easily get caught between the rib and the baffle, resulting in no When the drainage is carried out, the flap cannot be closely attached to the closed circulation port, and the insect-proof and deodorizing effect is lost, and the practicality is not good, and it is necessary to improve it.

The creator has the structure of pest control and odor-resistant water head, which is easy to be stuck between the ribs and the flap due to hair and dirt, so that the flap and the flow port cannot be closely fitted and closed, and the insect and odor-proof function is lost. Nai Si and the idea of creation, after many discussions on design and trial sample test, and many revisions and improvements, the final design of this creation.

The present invention provides an insect proof and odor-resistant water drop head structure, comprising: a base, a filter disc, a closing piece and an elastic stretching unit, wherein the base is gradually tapered from the top to the bottom, and the inside has a a drain channel, the drain end forms an open drain port, the filter disc is arranged on the drainage channel of the base, and a tube body is arranged downwardly at the center, and a stop surface is arranged at the lower end of the tube body, and the tube is disposed A accommodating groove is formed in the body, a through hole is formed in the center of the blocking surface, and the sealing piece is disposed under the drainage opening of the pedestal, and the elastic stretching unit is disposed in the accommodating groove inside the tube body of the filter disc. And the perforation of the pipe body stop surface is passed down and combined with the closing piece, so that the closing piece is elastically stretched upward by the elastic stretching unit and closely fits to the bottom of the base to close the drain hole, and can be pushed by water pressure The closing piece forms an opening of the drain opening.

The main purpose of the creation is that the drainage opening of the base is provided as an open shape without ribs, and no hair or dirt is caught between the ribs and the closing piece, so that the closing piece cannot be closely fitted to the closed drain when the drainage is not performed. In this case, a more effective and effective insect and odor-reducing effect can be achieved.

Please refer to the first figure, the second figure, the third figure and the fourth figure. The creation of the insect proof and odor-resistant water drop head structure comprises: a base 1, a filter disc 2, a closing piece 3, and an elastic stretching unit. 4 and a cover 5, wherein the base 1 is tapered from the top to the bottom, and has a drainage channel 11 therein. The lower end of the drainage channel 11 defines an open drain opening 12, and the inner edge wall is provided with a cover. The filter plate 2 is disposed on the receiving portion 13 of the drainage channel 11 of the base 1, and the filter plate 2 is provided with a plurality of filter holes 21, and a central portion is provided with a tube body 22 extending downward. A blocking surface 221 is defined in the lower end of the tube body 22, and a receiving groove 222 is formed in the tube body 22. A through hole 223 is defined in the center of the blocking surface 221, and the sealing piece 3 is disposed on the drain opening of the base 1. The lower end of the 12 is provided with a coupling hole 31. The elastic stretching unit 4 includes a limiting rod 41, a blocking member 42 and a spring 43. The limiting rod 41 is provided with an enlarged head 411 at one end and at the other end. The external thread 412 has a threaded hole 421. The spring 43 is sleeved on the limiting rod 41, and is received in the receiving groove 222 of the tubular body 22 of the filter disc 2. So that the spring 43 against the elastic limit the rod 41 and the lower end 411 of the head 221 the tube 22 filter disc stopper surface 2, and the stopper lever 41 is provided an external thread 412 A through hole 223 is formed in the center of the blocking surface 221 of the tubular body 22, and is passed through the coupling hole 31 of the closing piece 3 and the screw hole 421 of the blocking member 42 to be screwed and fixed, so that the closing piece 3 is combined with the limiting rod 41. The cover 5 is used to cover an opening that closes the upper end of the tubular body 22 of the filter disc 2.

Therefore, when the water drop head is not drained, the sealing piece 3 of the sealing piece 3 is elastically stretched upward by the elastic force of the spring 43, so that it closely fits to the bottom of the base 1 to close the drain port 12, thereby forming a barrier function. In order to prevent the pest from entering the room by the falling head, and to prevent the odor in the drain pipe from being diverged to the indoor pest control and odor-reducing effect.

When draining, as shown in the fifth figure, the water outlet is pushed against the drain opening 12 of the closing piece 3 away from the bottom of the base 1, so that the drain opening 12 is opened, and the sealing piece 3 is stretched downward by the sealing piece 3. The rod 41 is compressed downward by the head 411 of the limiting rod 41 to accumulate the elastic force, thereby imparting a normal drainage function, and after the drainage is completed, the closing piece 3 can be pushed back by the resilience of the spring 43. It is closely attached to the bottom of the base 1 to close the drain port 12 to form a barrier function, thereby constituting the insect-proof, deodorant and normal drainage function of the original water-dropping head.

Furthermore, in the present invention, the base 1, the filter disc 2, the closure piece 3, the elastic stretching unit 4 and the cover 5 can be installed in a casing, and the casing is covered with a filter hole. Cover.

According to the structure of the above specific embodiment, the following benefits can be obtained: the insect-proof and odor-resistant water drop head structure of the present invention, the drain opening 12 of the base 1 is provided as an open shape without ribs, so that no hair or dirt is stuck on the ribs. Between the sealing sheet 3 and the sealing sheet 3, the sealing sheet 3 cannot be closely fitted to the closed drain opening 12, so that the falling head can obtain more effective and effective insect and odor-reducing effects, and prevent pests such as cockroaches in the drain pipe or The odor invades the room to maintain the sanitation of the indoor environment.

In summary, this creation has indeed reached a breakthrough structure, and has improved content of creation, while at the same time achieving industrial use and progress. When complying with the provisions of the Patent Law, it proposes a new type of patent application according to law. The census review committee granted legal patent rights and was praying.
