Description

Technical Field

[0001] The invention belongs to the field of mechanical technology and relates to an anti-odor drain device, in particular to an anti-odor drain device which can be automatically closed under the action of magnetic force. Background Art

[0002] Water is an indispensable resource in people's daily life. In addition to drinking, domestic water also accounts for a large part, and the drainage pipes and drainage devices used to discharge domestic water are also indispensable. Take the floor drain as an example. It is set on the ground and used to discharge water from the ground in various places. The magnetic floor drain is a type of floor drain. It uses magnetic force to enable the floor drain to automatically open and drain under the action of water gravity, and automatically reset and close the drainage after the drainage is completed. It can effectively prevent water overflow and the release of odor and mosquitoes, and is increasingly used in people's daily life.

[0003] For example, the applicant has designed a magnetic levitation floor drain core and applied for a Chinese patent (its application number is: 201611270023.X; its announcement number is CN106759809B). The magnetic levitation floor drain core includes a cylindrical body, a cylindrical inner shell connected to the body, and a seal. The lower end of the cylinder is connected to a bracket. The seal includes a rod-shaped rod and a sealing part fixed to the upper end of the rod. The rod is inserted into the bracket. A reset mechanism is provided between the seal and the bracket to reset the seal upward after the seal moves downward. The reset mechanism includes a magnetic part 1 and a magnetic part 2 connected to the bracket and the rod, respectively. The seal can move upward and abut against the lower end of the inner shell under the action of the magnetic force between the magnetic part 1 and the magnetic part 2.

[0004] However, due to the volume limitation of the floor drain, the volume of magnetic parts one and two in the magnetic levitation floor drain core is often small, and the magnetic force is relatively small. During use or after long-term use, the seal may fail to reset and close the drainage due to the small magnetic force, and the reliability of use is limited.

[0005] In the face of this problem, the commonly used technical means is to increase the volume of magnetic component 1 and magnetic component 2 or increase the number of magnetic component 1 and magnetic component 2 to enhance the magnetic force between the two to ensure that the force on the seal is large enough. However, too large or too many magnetic components 1 and magnetic components 2 will occupy more space. Without affecting the water flux, the effect of increasing the size and number of magnetic components 1 and magnetic components 2 is limited. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose an anti-odor drainage device, which solves the problem that the sealing member in the prior anti-odor drainage device is difficult to re-seal stably.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] A deodorizing drainage device comprises a shell with a water hole, a bracket connected to the shell and a sealing cover, wherein magnets are fixed on the bracket and the sealing cover, and the sealing cover can seal the water hole under the magnetic force of the magnet. The device is characterized in that at least one of the magnets is provided with a shielding member, which is made of magnetic conductive material and fixed on the side of the magnet away from other magnets.

[0009] When the odor-proof drainage device is in use, the shell can be fixed in the drainage channel and remain motionless. There is a magnetic force between the sealing cover and the magnet on the bracket, which can be specifically a magnetic attraction force or a magnetic repulsion force. Under the action of the magnetic force, the sealing cover moves up relative to the bracket and blocks the water hole on the shell to prevent water from overflowing and the release of mosquitoes and odors. When draining water, the sealing cover overcomes the magnetic force and moves down under the gravity of the water flow, reopens the water hole, and allows the water flow to be discharged smoothly.

[0010] In the present odor-proof drainage device, a shielding member made of a magnetic conductive material is fixed on the side of the magnet away from other magnets, so that the magnetic field on this side of the magnet is shielded, thereby enhancing the magnetic field strength of other unshielded positions of the magnet, including the magnetic field strength of one side where several magnets are close to each other, thereby achieving the effect of enhancing the magnetic force of the magnet without increasing the volume and number of the magnet. Without affecting the water flow rate, the sealing cover can be stably reset under the action of a stronger magnetic force to seal the water hole, thereby ensuring the sealing.

[0011] In the above-mentioned odor-proof drain device, at least one of the magnets is in a columnar shape, and the shielding member is in a cylindrical shape and is sleeved on the outside of the magnet. The columnar magnet is only covered on the outer side, leaving two end faces with magnetic poles, which can effectively shield unnecessary magnetic fields and maximize the magnetic field at the two end poles, so that the sealing cover can be stably reset under the action of a stronger magnetic force to block the water hole, thereby ensuring the sealing performance.

[0012] As another aspect, in the above-mentioned deodorizing drainage device, at least one of the magnets is annular, the shielding member is cylindrical, and the shielding member is fixed to the inner side and / or outer side of the magnet. Depending on the exposed side of the magnet, the shielding member can be arranged on different sides of the magnet to obtain a better shielding effect.

[0013] As another aspect, in the above-mentioned odor-proof drain device, the outer surfaces of the magnet except the end surface close to other magnets are all covered with the above-mentioned shielding member. The shielding member is used to shield all the magnetic fields at other positions on the magnet that are not needed, leaving only one end surface that is needed, thereby maximizing the strength of the magnet.

[0014] In the above-mentioned deodorizing drainage device, the shielding member is in sheet shape.

[0015] In the above-mentioned deodorizing drainage device, the shielding member is in contact with the outer surface of the magnet. The shielding member is in contact with the surface of the magnet that needs to be shielded without leaving too much gap, so that there is no magnetic field between the two, and the magnetic field at other unshielded surfaces of the magnet is better enhanced.

[0016] In the above-mentioned odor-proof drainage device, two magnets are fixed on the sealing cover, and the two magnets are respectively located above and below the magnet on the bracket. According to different requirements of the drainage environment and the size of the odor-proof drainage device, a magnet can be added to the sealing cover to enhance the magnetic force exerted on the sealing cover.

[0017] In the above-mentioned deodorizing drainage device, the above-mentioned shielding member is fixed on both magnets on the sealing cover. Fixing the shielding member on both magnets further increases the magnitude of the magnetic force on the sealing cover and improves the stability of the movement of the sealing cover.

[0018] In the above-mentioned deodorizing drainage device, the shell and the bracket are connected as one body.

[0019] A deodorizing drainage device comprises a shell with a water through hole, a bracket connected to the shell and a sealing cover, wherein a magnet is fixed on the bracket, and a fixing piece made of ferromagnetic material is fixed on the sealing cover. The sealing cover can block the water through hole under the action of the magnetic force between the magnet and the fixing piece, and is characterized in that a shielding piece is arranged on the magnet, and the shielding piece is made of magnetic conductive material and fixed on the side of the magnet away from the fixing piece.

[0020] The present deodorizing drainage device replaces the magnet on the sealing cover with a fixing piece made of ferromagnetic material, wherein the ferromagnetic material may be iron, nickel, cobalt, etc., which can be adsorbed by the magnet. Then, the sealing cover can also move up and block the water hole under the action of the magnetic force between the magnet and the fixing piece, and the shielding piece fixed on the side of a single magnet can also shield the magnetic field on that side of the magnet, thereby enhancing the magnetic field strength at other positions of the magnet, and also improving the stability of the moving seal of the sealing cover. Of course, according to the actual structural requirements of the deodorizing drainage device, the fixed positions of the magnet and the fixing piece can also be exchanged, that is, the fixing piece is fixed on the bracket, and the magnet is fixed on the sealing cover, and the shielding piece is also fixed at the corresponding position on the magnet of the sealing cover. The sealing cover can also block the water hole of the shell under the action of the magnetic force between the magnet and the fixing piece.

[0021] In the above-mentioned deodorizing drainage device, the magnet is in a columnar shape, and the shielding member is in a cylindrical shape and is sleeved on the outside of the magnet. The columnar magnet is only covered on the outer side, leaving two end faces with magnetic poles, which can effectively shield unnecessary magnetic fields and maximize the magnetic field at the two end poles, so that the sealing cover can be stably reset under the action of a stronger magnetic force to block the water hole, thereby ensuring the sealing performance.

[0022] As another case, in the above-mentioned deodorizing drainage device, the magnet is annular, the shielding member is cylindrical, and the shielding member is fixed to the inner side and / or outer side of the magnet. Depending on the exposed side of the magnet, the shielding member can be arranged on different sides of the magnet to obtain a better shielding effect.

[0023] As another aspect, in the above-mentioned odor-proof drain device, the outer surfaces of the magnet except the end surface close to other magnets are all covered with the above-mentioned shielding member. The shielding member is used to shield all the magnetic fields at other positions on the magnet that are not needed, leaving only one end surface that is needed, thereby maximizing the strength of the magnet.

[0024] In the above-mentioned deodorizing drainage device, the shielding member is in contact with the outer surface of the magnet. The shielding member is in contact with the surface of the magnet that needs to be shielded without leaving too much gap, so that there is no magnetic field between the two, and the magnetic field at other unshielded surfaces of the magnet is better enhanced.

[0025] In the above-mentioned deodorizing drainage device, the shell and the bracket are connected as one body.

[0026] Compared with the prior art, the odor-proof drainage device shields part of the magnetic field of the magnet by adding a shielding part on the magnet, thereby enhancing the magnetic field strength of other unshielded parts of the magnet. The magnetic force of the magnet is enhanced without increasing the number and volume of the magnets, thereby achieving the effect of enhancing the sealing stability of the sealing cover when resetting the seal without affecting the water flow rate.

[0045] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0046] like Figure 16 to Figure 21 As shown, when the shielding member 4 is not connected to the outside of the magnet 2, the magnetic field of the magnet 2 diverges in all directions, and when the shielding member 4 is connected to one side of the magnet 2, the magnetic field on that side of the magnet 2 is shielded, and the magnetic field at the unshielded part of the magnet 2 is enhanced. Here, the shielding member 4 can be made of magnetic conductive materials such as iron and silicon steel.

[0047] Hereinafter, the odor-proof drainage device is described using a floor drain structure as an example, but is not limited to the floor drain structure shown in the accompanying drawings, nor is it limited to the use of floor drains, and can be applied to various odor-proof drainage devices with similar structures.

Among them, shielding parts 4 are arranged on the three magnets 2, and the shielding parts 4 are made of magnetic conductive material and fixed to the outside of the magnet 2 and abut against the magnet 2.
