M249978 V. Creation Instructions (1) '------ I. New Technology Field: ^ Creation is about a diaphragm type downspout, especially to provide a type of t. Alas, there is a set of isolation devices with a diaphragm type head that has deodorant, mosquito and insect resistance functions. 2. Previous technology: 〇 This creation is about the re-improved creation of the "drain head" (as shown in Annexes 1 and 2) with deodorant, mosquito and insect resistance functions in China Patent Bulletin Nos. 2 1687 and 287 567. case. According to the Announcement No. 2 1 0 6 8 7 "Structural Improvement of the Drain Head" (as attached, shown, hereinafter referred to as the case of citation), of course, it already has the function of deodorization "; The deodorant structure design is mainly around the periphery of the collecting hole (62) of the downwater head fixed seat (60) (the main seat as the case is called), and an arched hollow cover (63) is extended upward to protrude; and The bottom surface of the sink head (20) (that is, the same as the filter cover referred to in this case) is formed by extending a bowl-shaped bowl (5 3) on one side. Therefore, when the case is cited, it can be borrowed. Between the outer side of the cover body (63) of the fixed seat (60) and the conical leakage surface (61) on the inner side; some water to be discharged is used to flood the inverted bowl-shaped shape under the water head (20) The bowl body (53) prevents the odor in the drainage pipe from rising upward into the room, and has the function of deodorizing. However, when the cited case is used for drainage, water must first accumulate on the conical leakage surface ( In 6 1), after the cover (6 3) is overrun (full), it can pass through the perforation (6 3 0) in the center of the cover (6 3). ) Into the drainage pipe for drainage, so the drainage action is not very smooth; and it is easy to produce scale or debris between the outer side of the cover (6 3) and the conical leakage surface (6 1), leading to odor; It is more likely to block drainage, so it only has π short-term π

M249978 Five 'creative description (2)' s deodorization 'function, but users who are likely to cause poor drainage feel that there is a "debate", which is very unrealistic. Even though the industry has created a more drainage-friendly sundries Or the announcement of fouling No. 287 567 "valvular bathroom (such as Annex II, hereinafter referred to as the second case), in order to achieve the function of insect control". Because the "valve-type falling-over cover (20)" and the base (40) (like the main seat of the case) of the cited second case consist of an elastic plastic valve (30); Each filter hole (21) on (20) is provided with a wide gap in the corresponding space, and a large filter cover (20) is left in the center (between) and the base (40). The undersides of each are tightly attached. Therefore, when installed and used, it is in an unshielded state. Not only does it not have the function of "deodorant", mosquitoes and insects will climb up from the gaps of the valves (3 2) and the center thereof. And indoors, there is no anti-mosquito, beneficial points are impractical. In view of the above two cases and other general insects and insects falling into the head, neither of them has the function of "odor and insect resistance". "Diaphragm Drain". Third, the new content: missing, so that the installation is useful. Smooth and difficult to accumulate the water head structure "It has both π deodorant and water head π, tied between the bucket grooves, and the valves (3 2) on the rubber valve (30) are perforated; the filter holes (2 1) installed are completely Continuity, 'The perforation in the drain pipe is freely functioning, so it is still used in the deodorant used in the past.'
