Technical Field

[0001] This utility model relates to the field of floor drain technology, and more specifically, it relates to an anti-clogging and anti-odor floor drain core. Background Technology

[0002] Floor drains are widely used in kitchens and bathrooms. With their functions of preventing odors, insects, blockages, and backflow, they have become an indispensable drainage facility in people's lives, ensuring the cleanliness of kitchens and bathrooms.

[0003] Currently, traditional water-sealed floor drains mainly utilize the water stored in the U-shaped water storage area to achieve a water-sealed odor-proof effect. However, they have three main drawbacks: the U-shaped water storage area structure makes it difficult for water to flow through, resulting in a small drainage flow rate and making it easy to cause blockages and backflows in the drain pipes. This structure cannot effectively satisfy both the two core functions of drainage and odor prevention at the same time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clog-proof and odor-proof floor drain core to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clog-proof and odor-proof floor drain core, comprising a floor drain body, a drainage cavity formed inside the floor drain body, an opening on the top surface of the drainage cavity and a floor drain panel installed thereon, an odor-proof core that cooperates with the drainage cavity installed inside the floor drain panel, the odor-proof core and the drainage cavity cooperate to form a first layer of sealing and odor prevention, the bottom of the drainage cavity has a first odor-proof part and a second odor-proof part, the first odor-proof part and the second odor-proof part are in an hourglass shape, and a first blocking ball and a second blocking ball are respectively arranged inside the first odor-proof part and the second odor-proof cavity.

[0007] The present invention is further configured such that: the odor-proof core has an inverted trumpet-shaped structure and a contact section, and the odor-proof core is made of a flexible material with good shape memory properties.

[0008] The present invention is further configured such that: the odor-proof core is detachably installed inside the drain panel by means of a fixing member, and the top center of the odor-proof core is formed with an installation hole that matches the fixing member.

[0009] The present invention is further configured such that: the fixing part includes a rotating part and a threaded fixing part, and a threaded hole adapted to the fixing part is formed at the center of the inner surface of the drain panel; the threaded fixing part corresponds to the size of the mounting hole and is threadedly connected to the threaded hole.

[0010] The present invention is further configured such that: the fixing member is a funnel-shaped structure adapted to the top of the inner cavity of the odor-proof core, and the lower surface of the fixing member is formed with a force-bearing part.

[0011] The present invention is further configured such that: the first odor-proof part is located above the second odor-proof part, the first odor-proof part is inverted triangular in shape, the second odor-proof part is equilateral triangular in shape, the first blocking ball corresponds to the bottom of the first odor-proof part, and the second blocking ball corresponds to the top of the second odor-proof part.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1As shown, an embodiment of the present invention provides a drain core for preventing blockage and odor, comprising a drain body 1, a drain cavity 2 formed inside the drain body 1, an opening on the top surface of the drain cavity 2 and a drain panel 3 installed thereon, an odor-proof core 30 that cooperates with the drain cavity 2 installed inside the drain panel 3, the odor-proof core 30 and the drain cavity 2 cooperate to form a first layer of sealing and odor prevention, the bottom of the drain cavity 2 has a first odor-proof part 20 and a second odor-proof part 21, the first odor-proof part 20 and the second odor-proof part 21 are hourglass shaped, and a first blocking ball 22 and a second blocking ball 23 are respectively provided in the first odor-proof part 20 and the second odor-proof cavity.

[0018] During use, water on the ground surface flows into the drainage chamber 2 through the drain panel 3. The odor-proof core 30 can achieve adaptive sealing according to the usage state of the drain panel 3. The odor-proof core 30 and the drainage chamber 2 cooperate to form the first layer of odor-proof sealing. There is a flow channel between the first odor-proof part 20 and the second odor-proof part 21. When the drain is not draining, the first plug ball 22 blocks the flow channel to form the second layer of odor-proof sealing. When draining, the water passes through the first odor-proof core 30 and reaches the first odor-proof part 20, causing the first plug ball 22 to float. At this time, the water flows from the first odor-proof part 20 to the second odor-proof part 21 (the bottom of the second odor-proof part 21 is densely covered with a large number of drainage holes) and is discharged. When the drain backs up, the second plug ball 23 floats up under the action of water pressure, thereby blocking the flow channel between the first odor-proof part 20 and the second odor-proof part 21 to prevent backflow.

[0019] This utility model provides a first layer of odor prevention (soft seal) by setting an odor-proof core 30, a second layer of odor prevention (hard seal) by setting a first odor-proof part 20, and prevents the floor drain from leaking water by setting a second odor-proof part 21. It subverts the traditional floor drain structure (which uses water in the U-shaped water storage area to achieve a water seal), has a larger drainage volume, faster drainage speed, more thorough odor prevention and sealing, is less prone to clogging, and effectively avoids sewage backflow.

[0020] The top surface of the drain panel 3 has an arc structure and several drain outlets 31. Inside the drainage cavity 2, guide slopes 24 are formed at the corresponding positions of each drain outlet 31.

[0021] During use, external water flows into the drainage chamber 2 through the drain outlet 31 of the drain body 1. After falling onto the guide slope 24, the water comes into contact with the odor-proof core 30. By setting the guide slope 24, the water is prevented from directly contacting and colliding with the odor-proof core 30 during drainage, thus avoiding affecting the service life of the odor-proof core 30.

[0022] The odor-proof core 30 has an inverted trumpet-shaped structure and a contact section 32. The odor-proof core 30 is made of a flexible material with good shape memory properties.

[0023] When in use, without drainage, the contact section 32 of the odor-proof core 30 is sealed to the inside of the drain cavity 2, forming the first layer of odor prevention for the drain, preventing odors in the pipe from seeping into the ground from the drain cavity 2. When draining, water overflows into the drain cavity 2 through the drain outlet 31. Under the action of gravity, the contact section 32 of the odor-proof core 30 deforms, and a water passage gap is formed between the inner wall of the drain cavity 2 and the contact section 32, allowing the drain to drain normally. The odor-proof core 30 is preferably made of flexible rubber material (silicone rubber).

[0024] The odor-proof core 30 is detachably installed inside the drain panel 3 via the fastener 33. The top center of the odor-proof core 30 has a mounting hole 34 that matches the fastener 33. The fastener 33 includes a rotating part 35 and a threaded fixing part 36. The center of the inner surface of the drain panel 3 has a threaded hole 37 that matches the fixing part. The threaded fixing part 36 corresponds to the size of the mounting hole 34 and is threadedly connected to the threaded hole 37. The fastener 33 is a funnel-shaped structure that matches the top of the inner cavity of the odor-proof core 30. The lower surface of the fastener 33 has a force-bearing part 38.

[0025] When using the odor-proof core 30, the threaded fixing part 36 of the fixing part 33 is passed through the preset mounting hole 34 of the odor-proof core 30, and then the threaded fixing part 36 is tightened to the threaded hole 37 on the inner surface of the drain panel 3. The installation and fixing of the odor-proof core 30 is completed when the threaded fixing part 36 is tightened in place. The odor-proof core 30 and the drain panel 3 are detachably connected, which is convenient for daily maintenance and replacement.

[0026] The fixing part adopts a funnel-shaped structure that fits the top of the inner cavity of the odor-proof core 30, providing support for the main structure of the odor-proof core 30 so that the odor-proof core 30 can quickly return to its original position after deformation. The force-bearing part 38 provides a stable force point for the rotation of the fixing part.

[0027] The first odor-proof part 20 is located above the second odor-proof part 21. The first odor-proof part 20 is in the shape of an inverted triangle, and the second odor-proof part 21 is in the shape of an upright triangle. The first blocking ball 22 corresponds to the bottom of the first odor-proof part 20, and the second blocking ball 23 corresponds to the top of the second odor-proof part 21.

[0028] In use, the first odor-proof part 20 and the second odor-proof part 21 are connected by threads, which facilitates daily maintenance and replacement.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
