Abstract
Description
Technical Field
[0001] This utility model relates to the field of drain mat technology, specifically to a drain mat that prevents backflow of odors and mosquitoes. Background Technology
[0002] In modern building drainage systems, floor drains play a crucial role as a key component connecting the interior to the sewer system. However, existing floor drain openings often become sources of indoor odors and breeding grounds for mosquitoes. Sewage and garbage accumulating in the sewer system produce various unpleasant odors through the decomposition of microorganisms. These odors diffuse into the room through the floor drain openings, severely affecting indoor air quality and the comfort of the living environment.
[0003] At the same time, the damp environment and residual dirt in the drain provide ideal conditions for mosquitoes to breed. Mosquitoes not only interfere with people's normal lives, but may also spread diseases and pose a threat to human health.
[0004] Most existing drain mats on the market simply seal the drain opening. While this method can prevent odors and insects from entering the room when the drain mat is closed, the odors from the sewer will still seep into the room when the drain is opened to drain water. Therefore, in practical use, the odor and insect problems are not fundamentally and effectively solved, still causing considerable inconvenience to residents. There is an urgent need for a new type of drain mat that can more comprehensively and effectively solve the problems of drain odors and insects. Utility Model Content
[0005] This utility model proposes a drain mat that prevents odors and mosquitoes, solving the problem that drain mats that only use a sealing method in related technologies have poor odor prevention effects.
[0006] The technical solution of this utility model is as follows: A drain mat for preventing odors and mosquitoes includes a main body and a supporting part. The main body has a receiving cavity for receiving mosquito-repellent or odor-repellent items. The end of the receiving cavity facing the room is sealed. The supporting part is used to support the mosquito-repellent or odor-repellent items in the receiving cavity. The supporting part has at least one vent for connecting the receiving cavity and the drain opening.
[0007] Optionally, the support portion includes a mounting ring and a mesh panel. The mounting ring is detachably inserted into the receiving cavity, and the mesh panel is located at the bottom of the mounting ring. The vent is a mesh on the mesh panel, and there are multiple vents.
[0008] Optionally, a sealing cap may also be included, which is removably disposed on the top of the receiving cavity for placing an item into the receiving cavity from the top.
[0009] Optionally, the top of the sealing cap has a receiving groove, which is spherical and used to receive the aroma item. The inner wall of the receiving groove has several protrusions for supporting the aroma item.
[0010] Optionally, a cap may also be included, which is detachably mounted on the sealing cap to protect the scented item.
[0011] Optionally, the cap has a locking portion in its circumferential direction, and the sealing cap has a locking groove in its circumferential direction, the locking portion being used to engage with the locking groove.
[0012] Optionally, the cap has multiple vent holes that are evenly distributed along the circumference of the cap.
[0013] Optionally, the main body is a flexible gasket.
[0014] Optionally, the main body includes a cylindrical body and a flexible bag body, the first receiving cavity is formed on the cylindrical body, the flexible bag body surrounds the cylindrical body, and an annular second receiving cavity is formed between the cylindrical body and the flexible bag body for containing liquid.
[0015] Optionally, it may also include a hanging ring, which is disposed on the main body.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] Choose appropriate odor-absorbing items as needed, such as mothballs or aromatherapy products. Place the odor-absorbing item inside the main housing, with the support section at the bottom to firmly hold it in place. Because the support section has vents, the odor emitted by the odor-absorbing item can continuously enter the drain through these vents. Over time, even if odors are generated in the sewer and attempt to spread upwards, the odor-absorbing item's scent will mix with them, masking and suppressing the odor from entering the room. Simultaneously, mothballs themselves have insect-repelling and mosquito-repelling properties; their volatile scent entering the drain effectively prevents or reduces mosquito breeding near the drain. The top of the housing has a sealed cap for easy placement of items and is more hygienic than placing items from the bottom.
[0018] The flexible bag and liquid work together to better conform to the ground, while preventing gas leakage from the sewer due to uneven ground.
[0019] The receiving cavity can flexibly hold various odor-preventing items, such as mothballs, camphor balls, and aromatherapy products, meeting the needs of different users for scent preferences and odor-preventing strength. The vent in the supporting section creates an odor transmission channel from the odor-preventing item to the drain opening, allowing the item to function continuously, unlike traditional sealing drain mats which are only effective when closed. The receiving cavity of this product is sealed at the indoor-facing end, effectively preventing odors from spreading from the drain opening into the room for a long time, maintaining indoor air freshness and greatly improving the comfort of the living environment. Compared to traditional products that only rely on sealing to solve drain odor and insect problems, it has more comprehensive, longer-lasting, and more efficient advantages.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0030] Reference Figures 1-4 The first embodiment of this utility model proposes a drain mat for preventing odors and mosquitoes, including a main body 1 and a supporting part 2. The main body 1 has a receiving cavity 3 for receiving mosquito-repellent or odor-repellent items. The end of the receiving cavity 3 facing the room is sealed. The supporting part 2 is used to support the mosquito-repellent or odor-repellent items in the receiving cavity 3. The supporting part 2 has at least one vent 4 for connecting the receiving cavity 3 and the drain opening.
[0031] In this embodiment, a suitable odor-preventing item, such as mothballs or aromatherapy products, is selected as needed. The odor-preventing item is placed in the receiving cavity 3 of the main body 1, and the supporting part 2 is located at the bottom of the receiving cavity 3 to firmly support the odor-preventing item. Since the supporting part 2 is provided with a vent 4, the odor emitted by the odor-preventing item can continuously enter the drain outlet through the vent 4. Over time, even if an odor is generated in the sewer and attempts to spread upwards, the odor of the odor-preventing item will mix with it and play a role in masking and inhibiting the odor from spreading into the room. At the same time, mothballs themselves have insect-repelling and mosquito-repelling properties, and their volatile odor, after entering the drain outlet, can effectively prevent or reduce the breeding of mosquitoes near the drain.
[0032] The receiving cavity 3 can flexibly hold various odor-preventing items, such as mothballs, scented products, etc., to meet the needs of different users for scent preferences and odor-preventing strength. The vent 4 of the supporting part 2 creates an odor transmission channel from the odor-preventing items to the drain outlet, allowing the odor-preventing items to function continuously, unlike traditional sealing drain mats which are only effective when closed. The receiving cavity 3 of this product is sealed at the end facing the room, which can effectively prevent odors from spreading from the drain outlet into the room for a long time, always maintaining the freshness of the indoor air and greatly improving the comfort of the living environment. Compared with traditional products that only rely on sealing to solve the problems of drain odor and mosquitoes, it has more comprehensive, longer-lasting, and more efficient advantages.
[0033] Furthermore, the support part 2 includes a mounting ring 201 and a mesh 202. The mounting ring 201 is detachably inserted into the receiving cavity 3. The mesh 202 is located at the bottom of the mounting ring 201. The vent 4 is a mesh on the mesh 202, and there are multiple vents.
[0034] In this embodiment, the volatile gases from the odor-proof items are evenly diffused into the drain opening through the mesh. When it is necessary to clean the support part 2, simply pull the mounting ring 201 out of the receiving cavity 3 to easily clean the mesh 202, removing any residual dirt or impurities. Then, insert the mounting ring 201 back into the receiving cavity 3 to restore normal use.
[0035] The detachable nature of the mounting ring 201 facilitates cleaning and maintenance of the support part 2, extends the overall service life of the drain mat, and ensures that it is always in good working condition. The mesh 202 can stably support various odor-proof items, preventing them from falling into the drain and causing blockage. Its densely packed vents 4 ensure that the volatile gases from the odor-proof items can fully and smoothly enter the drain opening, maximizing the odor-proof and insect-repelling effects.
[0036] Furthermore, it also includes a sealing cover 5, which is detachably mounted on the top of the receiving cavity 3 for placing items into the receiving cavity 3 from the top.
[0037] In this embodiment, the sealing cap 5 tightly covers the top of the receiving cavity 3. Under normal conditions, the sealing cap 5 allows the odor-proof item to continuously and stably release odors into the drain opening through the vent 4 of the support part 2, while effectively inhibiting odors from flowing back into the room from the drain opening and preventing mosquitoes from breeding in the drain area and entering the room. The sealing cap 5 is detachable, making it convenient for users to replace and replenish the odor-proof item in the receiving cavity 3.
[0038] Furthermore, the top of the sealing cap 5 has a receiving groove 6, which is spherical and used to receive the fragrance item. The inner wall of the receiving groove 6 has several protrusions 7 for supporting the fragrance item.
[0039] Furthermore, it also includes a cap 8, which is detachably mounted on the sealing cap 5 to protect the scented item.
[0040] Furthermore, the cap 8 has a locking part 9 in the circumferential direction, and the sealing cover 5 has a locking groove 10 in the circumferential direction, and the locking part 9 is used to engage with the locking groove 10.
[0041] Furthermore, the cap 8 has multiple vent holes 11, which are evenly distributed around the circumference of the cap 8.
[0042] In this embodiment, when using the drain mat, a scented item such as a fragrance ball is first placed in the spherical receiving groove 6 at the top of the sealing cap 5. Because the inner wall of the receiving groove 6 has several protrusions 7, the fragrance ball is supported by these protrusions 7, allowing air circulation space at its bottom and around its sides, ensuring full contact with the air. The cap 8 is detachably installed on the sealing cap 5 by engaging with the circumferential groove 10 of the sealing cap 5 via the circumferential locking part 9, thus protecting the scented item. Simultaneously, multiple vent holes 11 on the cap 8 are evenly distributed circumferentially, allowing the fragrance of the fragrance ball to continuously diffuse into the room. During daily use, even with slight vibrations or impacts, the cap 8 effectively protects the fragrance ball from falling or being damaged. When the fragrance ball needs to be replaced, simply pull the cap 8 gently to disengage the locking part 9 from the groove 10, remove the cap 8, take out the old fragrance ball and replace it with a new one, and then snap the cap 8 back into place.
[0043] Furthermore, the main body 1 is a flexible gasket.
[0044] In this embodiment, the main body 1 can be a flexible gasket (such as a silicone sheet), which can adaptively deform according to the shape and size of the drain opening. The silicone material main body 1 can be easily bent, stretched, and fitted onto the drain opening. It can tightly fill gaps, forming a good sealing effect and ensuring that odors are effectively blocked below the drain.
[0045] Furthermore, the main body 1 includes a cylindrical body 101 and a flexible bag body 102. The first receiving cavity 3 is formed on the cylindrical body 101, and the flexible bag body 102 surrounds the cylindrical body 101. An annular receiving cavity 2 12 is formed between the cylindrical body 101 and the flexible bag body 102 for containing liquid.
[0046] In this embodiment, the main body 1 can also be a combination of a cylindrical body 101 and a flexible bag body 102. The flexible bag body 102 can be pre-filled with water, or water can be injected into the annular receiving cavity 12 between the cylindrical body 101 and the flexible bag body 102 through the water inlet 13 on the flexible bag body 102. Due to the gravity of the water, the flexible bag body 102 can deform, hanging downwards and tightly fitting around the drain opening. The receiving cavity 3 on the cylindrical body 101 then normally functions to hold odor-preventing items.
[0047] The flexible bag 102 deforms under the action of water, which can better fit the drain opening of various shapes and surface conditions, effectively making up for the unevenness or irregularity that may exist in the drain opening, further enhancing the sealing effect, and thus better preventing the emission of odors and the breeding of mosquitoes.
[0048] Furthermore, it also includes a hanging ring 14, which is disposed on the main body 1.
[0049] In this embodiment, when the user is cleaning the drain or maintaining the drain mat, the drain mat can be hung on a hook on the bathroom wall using the hanging ring 14 provided on the main body 1. When the drain mat needs to be dried after a period of use to remove any moisture or odors, it can also be hung in a well-ventilated location, such as a clothesline on a balcony, using the hanging ring 14, so that the drain mat can fully contact the air, accelerating the drying process and the dissipation of odors.
[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
