Description
Technical Field
[0001] This utility model relates to the field of floor drain technology, and in particular to a floor drain that prevents backflow of odors. Background Technology
[0002] A floor drain is an important interface connecting the drainage pipe system to the indoor floor. As a crucial component of the drainage system in a residence, a floor drain is installed in a low-lying area of the indoor floor (such as in bathrooms, balconies, kitchens, and shower areas) to drain standing water and connect the indoor floor drainage system to the sewer pipes. It serves as both a drainage inlet and a barrier to prevent sewer pests and germs from entering the indoor environment.
[0003] Existing drains can only serve a simple filtering and drainage function, but most sewage pipes discharge wastewater, which produces a lot of odor. Since the surface of the drain has dense holes, it cannot block the odor, causing the odor from the sewage pipe to escape through the drain. Therefore, we propose an anti-odor drain to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-odor floor drain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-odor floor drain includes a drain cover, which abuts against the top of a guiding mechanism, and a connecting pipe is connected to the bottom of the guiding mechanism. A drain plug is connected to the bottom of the connecting pipe, and a sealing mechanism is installed below the drain cover. The sealing mechanism is inserted into the connecting pipe and abuts against the top of a limiting sleeve.
[0006] Preferably, the guiding mechanism includes a guiding disc, the bottom of the drain cover abuts against the top of the guiding disc, and a support ring is fixedly connected to the lower outer side of the guiding disc.
[0007] Preferably, the inner wall of the guide plate is set as an inclined surface, the support ring is set as an annular shape, and the bottom end of the guide plate and the bottom end of the support ring are at the same level.
[0008] Preferably, multiple sets of plug-in blocks are fixed below the drain cover, and the cross-section of the multiple sets of plug-in blocks is set to L-shape. Multiple sets of snap-fit blocks are fixed inside the guide plate, and the surface dimensions of the multiple sets of plug-in blocks are the same as the spacing of the multiple sets of snap-fit blocks.
[0009] Preferably, the sealing mechanism includes a connecting shaft, which is installed inside the drain cover via a bearing, and the lower end of the connecting shaft is connected to a fixed plate via a bearing. The upper surface of the fixed plate abuts against a rotating plate. Multiple sets of through holes of the same size are equally spaced inside the fixed plate and the rotating plate. A toggle plate is fixedly connected to the upper end of the connecting shaft, and a fixed rod is fixedly connected inside the toggle plate.
[0010] Preferably, a connecting slider is fixedly connected to the lower surface of the rotating disk, and a groove adapted to the connecting slider is formed on the surface of the fixed disk.
[0011] Preferably, a sealing gasket is glued to the bottom of the fixing plate, the surface of the sealing gasket abuts against the top of the limiting sleeve, and the inner wall of the limiting sleeve is set as an inclined surface.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device uses a drain cover and guide plate for filtration and collection. Water can be discharged into the sewer pipe through the connecting pipe and drain plug. When the drain cover is not draining, the fixed rod can be turned to make the actuating plate drive the connecting shaft and rotating plate to rotate. As the rotating plate rotates, the connecting slider can slide along the groove opened in the fixed plate, which facilitates positioning the rotation range of the rotating plate and makes it easy to keep the through holes on the surface of the fixed plate and the rotating plate away from each other. This can seal the inside of the connecting pipe and prevent the odor from the sewer from being discharged through the drain cover and causing pollution to the surrounding environment.
[0013] 2. This device uses the drain cover to drive the plug-in block through the gap between multiple sets of snap-fit blocks, and by rotating the drain cover, the plug-in block and snap-fit block can be engaged with each other, which facilitates the connection and limiting between the drain cover and the guide plate. By removing and installing the drain cover, the rotating plate, the fixed plate, and the inside of the connecting pipe can be cleaned. At the same time, the fixed plate drives the sealing gasket to abut against the upper end of the limiting sleeve, which can increase the sealing performance below the fixed plate.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-5 An anti-odor floor drain includes a floor drain cover 1, which abuts against the top of a guide mechanism 4, and a connecting pipe 5 is connected to the bottom of the guide mechanism 4. A drain plug 6 is connected to the bottom of the connecting pipe 5. The surface of the drain plug 6 has dense drainage grooves to facilitate the drainage of water in the connecting pipe 5. A sealing mechanism 7 is installed below the floor drain cover 1. The sealing mechanism 7 is inserted into the connecting pipe 5 and abuts against the top of a limiting sleeve 8. The limiting sleeve 8 can limit and support the sealing mechanism 7.
[0018] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the guiding mechanism 4 includes a guiding plate 41, the bottom of the drain cover 1 abuts against the top of the guiding plate 41, and a support ring 42 is fixedly connected to the lower outer side of the guiding plate 41. The support ring 42 fixedly connected to the lower outer side of the guiding plate 41 can play a role in assisting the installation of the guiding plate 41.
[0019] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the inner wall of the guide plate 41 is set as an inclined surface, which can guide water. The support ring 42 is set as an annular shape, and the bottom end of the guide plate 41 and the bottom end of the support ring 42 are at the same level. The bottom end of the guide plate 41 and the bottom end of the support ring 42 are at the same level, which can facilitate the installation of the guide plate 41.
[0020] Furthermore, refer to Figure 3 and Figure 4It can be seen that multiple sets of plug-in blocks 2 are fixed below the drain cover 1, and the cross-section of the multiple sets of plug-in blocks 2 is set in an L shape. By setting the cross-section of the multiple sets of plug-in blocks 2 in an L shape, they can abut against each other with the snap-fit blocks 3. Multiple sets of snap-fit blocks 3 are fixed inside the guide plate 41. The surface size of the multiple sets of plug-in blocks 2 is the same as the spacing between the multiple sets of snap-fit blocks 3. By inserting the multiple sets of plug-in blocks 2 into the spacing between the multiple sets of snap-fit blocks 3, the plug-in blocks 2 and snap-fit blocks 3 can be snapped together when the drain cover 1 is rotated, which facilitates the connection and installation between the drain cover 1 and the guide plate 41.
[0021] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the sealing mechanism 7 includes a connecting shaft 71. The connecting shaft 71 is installed inside the drain cover 1 through a bearing, and the lower end of the connecting shaft 71 is connected to a fixed plate 72 through a bearing. The upper surface of the fixed plate 72 abuts against a rotating plate 73. The rotating plate 73 and the connecting shaft 71 are sleeved together, so that when the connecting shaft 71 rotates, the rotating plate 73 can rotate along the surface of the fixed plate 72, which facilitates the control of the functions of the fixed plate 72 and the rotating plate 73. Multiple sets of through holes of the same size are opened at equal intervals inside the fixed plate 72 and the rotating plate 73. The through holes of the same size opened inside the fixed plate 72 and the rotating plate 73 can facilitate drainage and sealing. A toggle plate 76 is fixedly connected to the upper end of the connecting shaft 71, and a fixed rod 77 is fixedly connected inside the toggle plate 76.
[0022] Furthermore, refer to Figure 3 and Figure 5 It can be seen that a connecting slider 74 is fixedly connected to the lower surface of the rotating disk 73, and a groove adapted to the connecting slider 74 is opened on the surface of the fixed disk 72. By rotating the rotating disk 73, the connecting slider 74 can slide along the groove, which plays the role of positioning and adjusting the rotating disk 73.
[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a sealing gasket 75 is glued to the bottom of the fixed plate 72. The surface of the sealing gasket 75 abuts against the top of the limiting sleeve 8, and the inner wall of the limiting sleeve 8 is set as a slope. The sealing performance of the bottom of the fixed plate 72 can be increased by the contact between the sealing gasket 75 glued to the bottom of the fixed plate 72 and the limiting sleeve 8.
[0024] Working principle: When this utility model is in use, the drain cover 1, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5By guiding the connecting pipe 5 and drain plug 6 into the drain opening through the guide plate 41, and causing the drain cover 1 to drive multiple sets of plug-in blocks 2 into the gaps of multiple sets of snap-fit blocks 3, and by rotating the drain cover 1, the multiple sets of plug-in blocks 2 and multiple sets of snap-fit blocks 3 can be engaged with each other, thereby causing the connecting shaft 71 to drive the fixed plate 72 and the sealing gasket 75 to abut against the surface of the limiting sleeve 8. At this time, the drain cover 1 can filter the water, and the water falls into the connecting pipe 5 through the guide plate 41. Thus, the water can be discharged through the drain plug 6 by overlapping the through holes inside the fixed plate 72 and the rotating plate 73. When the drain cover 1 is not in use, by moving the fixed rod 77, the moving plate 76 can drive the connecting shaft 71 to rotate, thereby causing the rotating plate 73 to drive the connecting slider 74 to rotate along the surface of the fixed plate 72, so that the through holes on the surfaces of the fixed plate 72 and the rotating plate 73 are far apart, and the inside of the connecting pipe 5 can be sealed. The above is the complete working principle of this utility model.
