[0043] like Figure 1 and 2 As shown, the utility model provides a protection device, which includes a power pin 1 and a conduction component 2; the conduction component 2 includes a conduction pin 21, a fixing member 22 and a spring 23; a first limiting portion 211 is formed at one end of the conduction pin 21; the fixing member 22 is formed with a through hole 221 along the extension direction; after assembly, the spring 23 is sleeved on the conduction pin 21 and is arranged between the first limiting portion 211 and the fixing member 22, and the conduction pin 21 is arranged in the through hole 221; in the first working state, the power pin 1 is pressed against one end of the conduction pin 21 along the axial direction of the conduction pin 21, and the other end of the conduction pin 21 is exposed from the through hole 221; in the second working state, the power pin 1 does not contact the conduction component 2. In the above embodiment, in the first working state, specifically corresponding to the closed state of the chamber cover 3 when used on the cyclone mill, the power pin 1 is against the conduction pin 21 of the conduction component 2, the spring 23 in the conduction component 2 is in a compressed state, compressed between the first limit portion 211 and the fixing member 22, and the other end of the conduction pin 21 is exposed from the fixing member 22; this state is actually caused by the following operations: the chamber cover 3 is closed, the power pin 1 on the chamber cover 3 pushes the conduction pin 21 in the conduction pin 2 on the cavity 4 to move and the spring 23 is compressed. The second working state, specifically corresponding to the open state of the chamber cover 3 when used on the cyclone mill, is the open state of the chamber cover 3, at which the power pin 1 is not in contact with the conduction component 2; this state is caused by the following process: the chamber cover 3 is opened, the spring 23 rebounds, and the conduction pin 21 is reset under the thrust of the spring 23.
[0044] In a Figure 1 and 2 In the specific embodiment shown, a second limiting portion is formed in the fixing member 22 , and after assembly, the spring 23 is sleeved between the first limiting portion 211 and the second limiting portion.
[0045] In a more specific embodiment, the second limiting portion is an annular structure, and the inner diameter of the hole of the annular structure is smaller than the outer diameter of the spring 23 and larger than the outer diameter of the tail end of the conductive pin 21 .
[0046] In a Figure 1 and Figure 2 In a specific embodiment shown in the figure, the first limiting portion 211 is an annular structure, and the maximum diameter of the annular structure is greater than the diameter of the spring 23 .
[0047] In a Figure 2 In the illustrated embodiment, a threaded structure is formed on the outer periphery of the fixing member 22 .
[0048] In a Figure 1 and 2 In the illustrated embodiment, a third limiting portion 222 is formed at the rear end of the fixing member 22 .
[0049] In a more specific Figure 1 or Figure 2 In the embodiment shown, the third limiting portion 222 is a protruding structure and has a regular shape, such as a regular hexagon or a square. When used, such as when installed on a cyclone mill, the third limiting portion 222 facilitates installation and removal of the conducting component 2.
[0050] In a Figure 1 and 2 In the illustrated embodiment, the power pin 1 is provided with a connecting and fixing portion 11 , a fourth limiting portion 12 and a power transmission portion 13 in sequence.
[0051] In a Figure 2 In the illustrated embodiment, a threaded structure is formed on the outer periphery of the connecting and fixing portion 11 .
[0052] In a specific embodiment, a first clamping structure is provided at the end of the power transmission part 13, and a second clamping structure is provided at the end of the transmission pin 21, and the first clamping structure matches the second clamping structure.
[0053] In a more specific embodiment, the first clamping structure can be a groove structure, and the second clamping structure can be a protrusion structure matching the groove structure. The matching of the first clamping structure and the second clamping structure can improve the stability of the conductive pin 21 and prevent shaking or tilting.
[0054] like Figure 3As shown, the utility model also discloses a cyclone mill, which includes a cyclone mill cavity 4, a cavity cover 3, a sensor and a protective device as described in any one of the above; the power pin 1 is arranged on the cavity cover 3; the conduction component 2 is arranged at the opening edge of the cyclone mill cavity 4; the power pin 1 is matched with the conduction component 2; the sensor is arranged on the cyclone mill cavity 4 close to the fixing part 22.
[0055] In a specific embodiment, the sensor is a proximity sensor and / or a pressure sensor.
[0056] In a specific embodiment, the cyclone mill further includes a controller, the sensor is used to sense the displacement or pressure of the conductive pin 21, and output a corresponding electrical signal to the controller, and the controller controls the working state of the cyclone mill according to the electrical signal.
[0057] In the above embodiment, when the cyclone mill chamber cover 3 is closed on the cavity 4, at this time, the power pin 1 pushes the conductive pin 21 to move and the spring 23 is compressed, the other end of the conductive pin 21 is exposed, the sensor senses the displacement or pressure of the conductive pin 21, and outputs a corresponding electrical signal to the controller, and the controller controls the cyclone mill to start working according to the electrical signal and in combination with other information. If the controller detects this electrical signal and receives the cyclone mill start working instruction, the cyclone mill starts working, and if any condition is missing, the cyclone mill does not work; when the cyclone mill is working, if the chamber cover 3 of the cyclone mill is forcibly opened, the spring 23 rebounds, and the conductive pin 21 is reset under the thrust of the spring 23, the pressure sensor cannot sense the pressure of the conductive pin 21 or the displacement sensor senses the displacement deviation of the conductive pin 21, and outputs a corresponding electrical signal to the controller, and the controller immediately controls the cyclone mill to stop working according to the electrical signal. The protective device can ensure that the cyclone mill can work normally only when the cavity cover 3 of the cyclone mill is closed. If the cavity cover 3 is forcibly opened when the cyclone mill is working normally, the cyclone mill will stop working immediately, thereby improving the safety of use.
[0058] In the above embodiment, the cyclone mill in the present application can achieve fast and accurate closing of the chamber cover 3 by means of the power pin 1 on the protection device and the clamping structure of the transmission component 2.
[0059] In a Figure 3 In the specific embodiment shown, the cavity cover 3 is formed with an assembly hole for the power pin 1. In a more specific embodiment, the power pin 1 is connected to the cavity cover 3 through a threaded structure of the connection fixing portion 11.
[0060] In a Figure 3In the specific embodiment shown, the cyclone mill cavity 4 is formed with an assembly hole for the conduction component 2. In a more specific embodiment, the conduction component 2 is connected to the cyclone mill cavity 4 via a threaded structure of a fixing member 22.
[0061] In a Figure 3 In the more specific embodiment shown, the maximum diameter of the contact surface between the fourth limiting portion 12 and the assembly hole of the conducting component 2 is larger than the assembly hole of the conducting component 2 .
[0062] In a Figure 3 In the specific embodiment shown, the fourth limiting portion 12 is tightly attached to the cavity cover 3 , a groove for accommodating the fourth limiting portion 12 is formed at a corresponding position of the cavity cover 3 , and the fourth limiting portion 12 is also sleeved with a sealing member.
[0063] In a more specific embodiment, the sealing member is a sealing ring and / or a sealing rubber layer.
[0064] In the above embodiment, the fourth limiting portion 12 cooperates with the accommodating groove of the chamber cover 3, the seal sleeved on the fourth limiting portion 12 and the assembly hole of the conductive component 2, which can effectively prevent the powder generated during the operation of the cyclone mill from entering the interior of the protective device, causing a short circuit in the equipment and causing a fire.
