DETAILED DESCRIPTION
[0027] In order to make the technical means, creation features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.
[0028] Reference Figures 1-4 As shown in the figure, the anti-odor joint for kitchen and bathroom drainage comprises a one-way flow pipe 1 and an X-shaped filter leak-proof pipe. The upper end of the one-way flow pipe 1 is mainly used for connecting a corrugated pipe below a kitchen vegetable washing pool or a bathroom water washing pool. A second sealing ring sleeve 5 is embedded and installed in the inner cavity of the upper end of the one-way flow pipe 1. The inner sleeve of the second sealing ring sleeve 5 is sleeved around the outer periphery of the water outlet at the lower end of the corrugated pipe, thereby playing a sealing connection role and preventing water leakage. The lower end of the X-shaped filter leak-proof pipe 2 is mainly used for connecting a drainage pipe fixedly installed on the ground below the kitchen vegetable washing pool or the bathroom water washing pool. A first sealing ring sleeve 4 is attached to the outer periphery of the second pipe 202. The outer ring of the first sealing ring sleeve 4 is sealed into the above-mentioned drainage pipe, thereby playing a good sealing and leak-proof role.
[0029] Reference Figure 2 The lower end of the one-way flow pipe 1 is coaxially fixedly connected with a first pipe 101. A flap 104 is rotatably connected to the water outlet at the lower end of the first pipe 101. A rotating shaft 102 is arranged at the rotatable connection between the flap 104 and the first pipe 101. A torsional spring 103 is rotatably connected to the outer periphery of the rotating shaft 102. The first end and the second end of the torsional spring 103 are respectively compressed and installed on the flap 104 and the first pipe 101. When the water inlet at the upper end of the one-way flow pipe 1 is not filled with water, the flap 104 can be automatically rotated and closed on the water outlet at the lower end of the first pipe 101 by the elastic force of the torsional spring 103, thereby effectively preventing the odor at the lower end of the first pipe 101 from spreading upward. When the water inlet at the upper end of the one-way flow pipe 1 is filled with water, the water in the one-way flow pipe 1 can press and open the flap 104 by virtue of its own gravity and the potential energy generated by the downward flow of water, so that the first pipe 101 at the lower end of the one-way flow pipe 1 can normally drain water.
[0030] Reference Figure 3 and Figure 4The X-shaped filter leakage-proof pipe 2 is provided with a vertical circular drainage cavity 201 and an inclined foreign matter filter cavity 204, the lower end of the first insertion pipe 101 is sealingly connected to the upper end of the circular drainage cavity 201 in the X-shaped filter leakage-proof pipe 2, the foreign matter filter cavity 204 is embeddedly installed with a filter screen cylinder 6, the upper end of the filter screen cylinder 6 is provided with a water receiving opening 601, the lower end of the first insertion pipe 101 is arranged directly above the water receiving opening 601, when the lower end of the first insertion pipe 101 drains water downward, the water flow needs to pass through the filter screen cylinder 6, the filter screen cylinder 6 can block the foreign matter in the water flow, effectively avoiding the blockage of the inner cavity of the drainage pipe below the kitchen vegetable washing pool or the bathroom washing pool, since the filter screen cylinder 6 is embeddedly installed in the foreign matter filter cavity 204 and is arranged to be inclined, the foreign matter blocked in the filter screen cylinder 6 is impacted by the water flow, flows downward along the inner wall of the filter screen cylinder 6 arranged to be inclined, approaches the end of the foreign matter filter cavity 204, and gradually accumulates upward, the upper end of the foreign matter filter cavity 204 and the upper end of the circular drainage cavity 201 are mutually crossed and communicated, and the end of the foreign matter filter cavity 204 in the X-shaped filter leakage-proof pipe 2 is detachably connected with the plug 3.
[0031] It should be noted that the top end of the first sealing ring sleeve 4 is coaxially and abuttingly connected with a limiting ring 203, the limiting ring 203 is fixedly connected with the outer wall of the lower end of the X-shaped filter leakage-proof pipe 2, and is used for limiting and fixing the first sealing ring sleeve 4, so that the position is stable when the drainage pipe is connected, the sealing effect is reliable, the upper end of the foreign matter filter cavity 204 is communicated and provided with a semicylindrical cavity 205 which is mutually embedded and positioned with the outer wall of the upper end of the filter screen cylinder 6, this structure makes the installation of the filter screen cylinder 6 in the foreign matter filter cavity 204 more stable and less likely to displace, and ensures the stability of the filtering effect, the third sealing ring sleeve 7 is extrudedly connected between the inner wall of the upper end of the circular drainage cavity 201 in the X-shaped filter leakage-proof pipe 2 and the outer wall of the first insertion pipe 101, further enhancing the sealing property of the connection between the first insertion pipe 101 and the circular drainage cavity 201, preventing the occurrence of water leakage, the lower end of the foreign matter filter cavity 204 and the lower end of the circular drainage cavity 201 are communicated and provided with a water passing cavity 206, the end of the water passing cavity 206 close to the circular drainage cavity 201 is not higher than the end far from the circular drainage cavity 201, and the main function is that the water entering the foreign matter filter cavity 204 can pass through the filter holes in the filter screen cylinder 6 downward and then flow into the lower end of the circular drainage cavity 201 again, ensuring the smoothness of the drainage.
[0032] Further supplement, the X-shaped filter leak-proof pipe 2 is made of transparent plastic, the material characteristics of the transparent plastic enable the user to more intuitively observe the foreign matter accumulation in the foreign matter filter cavity 204, because if the foreign matter accumulated in the foreign matter filter cavity 204 is too much to affect the normal drainage of the circular drainage cavity 201, when the user sees that the foreign matter accumulated in the foreign matter filter cavity 204 is too much, the user can unscrew the plug 3 at the lower end of the foreign matter filter cavity 204 in the X-shaped filter leak-proof pipe 2, pull out the filter screen cylinder 6, easily take out the foreign matter accumulated in the X-shaped filter leak-proof pipe 2, and clean, conveniently and quickly maintain the normal operation of the drainage joint.
[0033] In the actual installation and use of the kitchen and bathroom drainage deodorization joint in the embodiment, first, the upper end of the one-way flow pipe 1 is tightly connected with the corrugated pipe below the kitchen vegetable washing pool or the bathroom washing pool through the second sealing ring sleeve 5, and then the second insertion pipe 202 at the lower end of the X-shaped filter leak-proof pipe 2 is sealed and inserted into the drainage pipe fixedly installed on the ground through the first sealing ring sleeve 4. In the daily use process, when the wastewater generated by washing vegetables or washing is flowed from the upper end of the one-way flow pipe 1, the water flow opens the flap 104 by overcoming the elastic force of the torsional spring 103, and then flows into the drainage pipe through the first insertion pipe 101, the circular drainage cavity 201 and the water passage cavity 206. In this process, the foreign matter in the water flow is intercepted by the filter screen cylinder 6, and the foreign matter is accumulated at the end of the foreign matter filter cavity 204 along the inclined inner wall of the filter screen cylinder 6 under the action of water flow impact and self gravity. The user can regularly observe the foreign matter accumulation in the X-shaped filter leak-proof pipe 2, and when cleaning is needed, the plug 3 is unscrewed, the filter screen cylinder 6 is pulled out for cleaning, and after cleaning, the plug 3 is reinstalled, so that the continuous and effective operation of the deodorization joint is ensured, and the stable, efficient, deodorization, anti-clogging and anti-leakage of the kitchen and bathroom drainage is ensured.
