Description

Technical Field

[0001] The utility model belongs to the technical field of drains, and in particular relates to an odor-proof drain. Background Art

[0002] Drains are widely used as common drainage devices in daily life. For example, washing machine drainage or basin drainage usually requires connecting the drainage pipe to the sewer pipe. In the past, most households only connected them by plugging. Therefore, when the washing machine and other equipment have a large drainage volume, the drainage pipe is easy to fall out, causing sewage on the ground. Therefore, some drains that are specially connected to the drainage pipe and the sewer pipe to prevent the drainage pipe from falling off have appeared on the market, but ordinary drains cannot solve the problem of odor in the sewer pipe, resulting in odor backwashing, or even wastewater overflow, causing trouble.

[0003] In order to solve the above problems, Chinese patent CN203960955U discloses a drainage device connected to a basin drain. Although the drainage device in the above scheme has the advantages of odor prevention and firm connection, its water inlet channel and water outlet channel are on the same straight line, which makes the entire drain longer as a whole and has higher requirements on the installation environment. In addition, the internal odor prevention device has a complex structure, and the installation and replacement are not convenient, which has certain defects. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the deodorizing drainer of the utility model is specifically described below in combination with embodiments and drawings.

[0026] <Example 1>

[0027] Figure 1 It is a structural diagram of the deodorizing drainer according to Embodiment 1 of the present utility model.

[0028] Figure 2It is a cross-sectional view of the deodorizing drainer according to Embodiment 1 of the present utility model.

[0029] like Figure 1 and Figure 2 As shown, this embodiment proposes an anti-odor drain 10, including a main body 1 with a hollow interior and a cylinder 2 arranged inside the main body 1. The main body 1 is provided with a water inlet 11 and a water outlet 12. The water inlet 11 can be provided in the form of a water inlet interface for connecting a water inlet joint. The water outlet 12 is located at the bottom of the main body 1 for discharging water. Figure 2 As shown, the barrel 2 and the main body 1 are integrally formed, an inner flow channel 21 is opened in the middle of the barrel 2 along the axial direction, an outer flow channel 31 for connecting with the inner flow channel 21 is arranged between the outer periphery of the barrel 21 and the inner wall of the main body 1, and an anti-odor element 4 is movably arranged at the connection point between the inner flow channel 21 and the outer flow channel 31, and the anti-odor element 4 has an open state that connects the inner flow channel 21 with the outer flow channel 31 and a closed state that blocks the inner flow channel 21 from the outer flow channel 31. The inner flow channel 21, the outer flow channel 31 and the main body 1 are basically coaxially arranged or the axes of the three are parallelly arranged, and the inner flow channel 21 is located inside the outer flow channel 31, and the two are separated by the barrel 2. In actual situations, the barrel 2 and the main body 1 can also be arranged in a split form. When they are arranged in a split form, a sealing ring needs to be added between the barrel 2 and the main body 1 to separate the outer flow channel from the inner flow channel.

[0030] In this embodiment, if Figure 2 As shown, the inner flow channel 21 is connected with the water outlet portion 12 to form a water outlet channel, and the water outlet channel has a first water inlet 22 and a first water outlet 23. The first water outlet 23 leads to the water outlet portion 12, that is, the upper end and the lower end of the inner flow channel 21; the outer flow channel 31 is connected with the water inlet portion 11 to form a water inlet channel, and the water inlet channel has a second water inlet 32 ​​and a second water outlet 33. The normal drainage direction is: water flows into the water inlet portion 11, flows through the water inlet channel from the second water inlet 32 ​​and flows out from the second water outlet 33, then enters the water outlet channel from the first water inlet 22 after flowing out, and finally flows through the first water outlet 23 and flows out from the water outlet portion 12.

[0031] Figure 3 It is a cross-sectional view of the annular diaphragm of Example 1 of the utility model installed on the main body.

[0032] Figure 4 It is a cross-sectional view of the main body of Example 1 of the utility model.

[0033] like Figure 3-Figure 4As shown, the outer wall of the cylinder 2 is formed with a first mounting protrusion 24 at one end near the first water inlet 22, and the inner wall of the main body 1 is provided with a second mounting protrusion 13 corresponding to the first mounting protrusion 24 at the second water outlet 33, and the deodorizing element 4 is movably provided on the first mounting protrusion 24 and the second mounting protrusion 13. Specifically, in this embodiment, the first mounting protrusion 24 and the second mounting protrusion 13 are both inclined toward the bottom of the water inlet channel to form a cone-like annular surface, and the deodorizing element 4 is an annular diaphragm with an arc-shaped cross section with a downward concave middle portion, and the bottom surface facing the direction of the water inlet channel is an arc-shaped surface, and the two ends of the arc-shaped surface are used to abut against the first mounting protrusion 24 and the second mounting protrusion 13 respectively. When water flows from the second water outlet 33 to the first water inlet 22, the water flow pushes the anti-odor element to at least partially leave the first mounting protrusion 24 and / or the second mounting protrusion 13 in the open state, and the water flow can smoothly flow from the second water outlet 33 to the first water inlet 22; when there is no water flow passing through or the water flow overflows from the first water inlet 22 to flow to the second water outlet 33, the anti-odor element 4 will be in a closed state against the first mounting protrusion 24 and the second mounting protrusion 13 under its own gravity or water flow pressure, thereby isolating the water inlet channel and the water outlet channel, preventing the water flow from overflowing back into the water inlet channel, and also preventing the odor from overflowing, thereby playing a role in preventing odor and sewage overflow.

[0034] In this embodiment, the annular diaphragm can be a diaphragm made of rubber, which has a certain hardness and quality, so that when there is no external force, the bottom surface of the annular diaphragm can be directly placed on the first mounting protrusion 24 and the second mounting protrusion 13 due to gravity to form a closed state. Once water flows from the bottom to impact the annular diaphragm, the annular diaphragm can be opened when the impact force is greater than the gravity of the annular diaphragm, so that a gap is formed between the bottom surface of the annular diaphragm and the first mounting protrusion 24 and the second mounting protrusion 13, thereby opening the channel for water flow to pass through. When the water flow overflows from the first water inlet 22 of the water outlet channel, the water flow will form a downward pressure on the annular diaphragm, further pressing its bottom surface on the first mounting protrusion 24 and the second mounting protrusion 13, thereby forming a closed state to prevent water flow and odor from overflowing. The use of rubber material allows the bottom surface of the annular diaphragm to have good fit and sealing when in contact with the first mounting protrusion 24 and the second mounting protrusion 13.

[0035] In addition, in actual circumstances, one side of the annular diaphragm can be fixed to the first mounting protrusion 24 or the second mounting protrusion 13, while the other side forms an open structure with the corresponding second mounting protrusion 13 or the first mounting protrusion 24. The water flow only flushes open the open side, and conduction between the water inlet channel and the water outlet channel can also be achieved.

[0036] like Figure 4As shown, the water inlet 11 is at least one side water inlet (one in this embodiment, more than one can be provided in actual situations) provided on the side of the main body 1, and the side of the water inlet channel forms a second water inlet 32 ​​connected to the side water inlet. At the same time, the height of the side water inlet is lower than the height of the deodorizing element 4, the height of the first water inlet 22 is higher than the height of the deodorizing element 4, and the height of the first water outlet 23 is lower than the height of the deodorizing element 4, so that the water flow can pass smoothly and the deodorizing element can achieve better deodorizing and anti-overflowing effects. At the same time, see Figure 2 The outer flow channel 31 (i.e., the water inlet channel) is a structure with one end open and the other end closed. The open end is the second water outlet 33, and the bottom of the closed end is slightly lower than the bottom of the water inlet 11, so that a water seal can be formed at the closed end, further improving the anti-odor and anti-overflow effects.

[0037] like Figure 2 and Figure 4 As shown, the main body 1 is also provided with an opening 14 leading to the deodorizing element 4, and a cap 5 is provided on the opening 14 through a threaded cover. When the deodorizing element 4 needs to be replaced or cleaned, the cap 5 can be opened, the deodorizing element 4 can be taken out from the opening 14 for cleaning or replacement, and then put in and cover with the cap 5, which is very convenient. A sealing ring is provided between the cap 5 and the inner wall of the opening 14. In addition, a mounting portion 15 for mounting the main body 1 is provided at one end of the main body 1 located at the water outlet 12. The main body 1 can be mounted to a floor drain or a sewer pipe through the mounting portion 15 and then used.

[0038] <Example 2>

[0039] Figure 5 It is a schematic diagram of the water flow direction of Example 2 of the utility model.

[0040] This embodiment is basically the same as the above-mentioned embodiment 1, except that the outer flow channel 31 and the inner flow channel 21 are in opposite positions, that is, the outer flow channel 31 is connected with the water outlet 11 to form a water outlet channel, and the inner flow channel 21 is connected with the water inlet 12 to form a water inlet channel. In this case, the deodorizing drainer of this embodiment also includes a guide sleeve 6 arranged inside the main body 1, and the guide sleeve 6 is an annular cylindrical structure with a closed bottom and an open top. The bottom of the cylinder 2 is inserted into the guide sleeve 6 (or the two are arranged as one body), and a through hole 25 leading to the inside of the guide sleeve 6 is opened on the cylinder wall of the cylinder 2. The water outlet channel is provided between the outer periphery of the guide sleeve 6 and the inner wall of the main body 1, and the deodorizing element 4 is installed between the outer wall of the cylinder 2 and the inner wall of the guide sleeve 5, and its water flow direction is as follows: Figure 5 As shown in , the connection and blocking of the water inlet channel and the water outlet channel are the same as those in the above-mentioned embodiment 1. In this embodiment, the length of the guide sleeve 6 along the axis is less than the length of the cylinder 2 along the length direction, so that the water flow can form a water seal in the guide sleeve 6, further improving the anti-odor and anti-overflow effects.

[0041] <Example 3>

[0042] Based on the above-mentioned embodiments 1 and 2, in order to prevent the deodorizing element 4 (annular diaphragm) from being insufficiently stressed during resetting, a reset member for assisting the deodorizing element 4 in being in a closed state is provided on one side of the deodorizing element 4. The reset member may be a spring or a torsion spring. When a spring is used, the spring may be installed between the deodorizing element 4 and the cap 5, with one end of the spring being against the upper end surface of the deodorizing element 4. When a torsion spring is used, the torsion spring may be installed between the first mounting protrusion 24 or the second mounting protrusion 13 and the deodorizing element 4, with one end acting on the deodorizing element 4, so as to facilitate the resetting of the deodorizing element. When the deodorizing element 4 is under its own gravity or needs to be tilted for use, the deodorizing element 4 can close the channel with the assistance of elastic force to put it in a closed state.

[0043] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
