[0045] like Figure 1 As shown, further, the permanent magnet 6 is a rectangular parallelepiped structure, and the permanent magnet 6 is vertically arranged.

[0046] The beneficial effect of adopting the above further technical solution is that it is convenient to realize magnetic adsorption by adjusting the relative position of the permanent magnet and a pair of electrical soft iron.

[0047] like Figure 1 As shown, further, the bottom of the magnetic base housing assembly 7 is open, and the permanent magnet 6 has an S pole and an N pole.

[0048] The beneficial effect of adopting the above further technical solution is that the bottom opening of the magnetic base housing assembly facilitates the interaction between the magnetic base and the surface 11 to be attracted, and facilitates the magnetic attraction work by adjusting the relative position of the permanent magnet and a pair of electrical soft irons.

[0049] like Figure 1 As shown, further, a pair of the electrical soft irons 8 are both installed on the side walls of the circular cavity of the magnetic base housing assembly 7, and a non-magnetic conductive material 9 is provided between the pair of the electrical soft irons 8.

[0050] The beneficial effect of adopting the above further technical solution is that it is convenient to realize magnetic adsorption by adjusting the relative position of the permanent magnet and the pair of electrical soft irons. The non-magnetic conductive material is used to separate the pair of electrical soft irons.

[0051] like Figure 1 As shown, further, the pair of electrical soft irons 8 are both C-shaped structures, the pair of electrical soft irons 8 are arranged opposite to each other, and the permanent magnet 6 is located between the pair of electrical soft irons 8 .

[0052] The beneficial effect of adopting the above further technical solution is that the electrical soft iron is all C-shaped, which is convenient for the electrical soft iron to adapt to the circular cavity of the magnetic seat housing assembly. The permanent magnet is located between a pair of electrical soft irons, which is convenient for achieving magnetic adsorption by adjusting the relative position of the permanent magnet and the pair of electrical soft irons.

[0053] like Figure 1 As shown, the embodiment of the utility model provides a magnetic seat with a top surface controlled magnetic adsorption state, which is used in applications where adsorption control is required on the top surface of the magnetic seat.

The magnetic lines of force 10 of the permanent magnet are blocked by the non-magnetic conductive material in the magnetic base housing assembly 7 (under the blocking effect of the non-magnetic conductive material) and cannot circulate inside the magnetic base housing assembly 7. The magnetic lines of force 10 can only circulate between the S pole and the N pole through the electrical soft iron and the surface 11 to be attracted, thereby forming an adsorption state of the surface 11 to be attracted.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
