Therefore, they cannot be understood as limitations on the present invention.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] The following is combined with Figure 1-4 The utility model is further described.

[0026] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an intelligent electrical equipment protection switch, including: a housing 1, a control module assembly 2 and a dust-proof, heat-dissipating and arc-extinguishing component 3.

[0027] In the specific implementation, such as Figure 2 and Figure 3As shown, the control module assembly 2 is installed in the shell 1, and the control module assembly 2 includes a control unit 201 and a trigger component 202. The trigger component 202 includes a fixed contact 2021 electrically connected to the control unit 201, an elastic structure 2022 installed on the inner wall of the shell 1, and a movable contact 2023 controlled by the elastic structure 2022. The movable contact 2023 can be controlled to move by the elastic structure 2022. When the movable contact 2023 moves to contact with the fixed contact 2021, the protection switch can be triggered.

[0028] The dust-proof heat dissipation arc extinguishing component 3 is used to dissipate heat for the control module assembly 2 and to extinguish arcs for the trigger component 202. The dust-proof heat dissipation arc extinguishing component 3 includes an air intake shell 301, a dust barrier 302, an air pump 303 and an exhaust pipe 304. The air intake shell 301 is fixedly installed on the top of the shell 1. An air intake groove 6 is provided on one side of the air intake shell 301. The air pump 303 is fixedly installed in the air intake shell 301. The exhaust pipe 304 is installed at the output end of the air pump 303. The exhaust pipe 304 has at least two air outlet ends, and one of the air outlet ends corresponds to the trigger component 202.

[0029] The exhaust pipe 304 includes a connecting pipe 3041 and a heat dissipation pipe 3042. The connecting pipe 3041 is installed at the output end of the air pump 303 and one end is set in the shell 1. The heat dissipation pipe 3042 is located in the shell 1 and the center position is connected to the bottom of the connecting pipe 3041. A plurality of discharge pipes 9 are welded to the bottom of the heat dissipation pipe 3042. The air pump 303 can draw the outside air into the shell 1 through the air inlet groove 6, and then the air flow can be discharged through the connecting pipe 3041 and the discharge pipe 9 and blown onto the control unit 201 to achieve a heat dissipation effect.

[0030] Furthermore, the exhaust pipe 304 also includes a branch pipe 3043. Corresponding pipe groove groups are provided on the shell 1 and the air inlet shell 301. One end of the branch pipe 3043 passes through the pipe groove group and is arranged in the shell 1 and corresponds to the trigger component 202. The branch pipe 3043 can guide the airflow to the trigger component 202 to extinguish the arc of the trigger component 202.

[0031] Furthermore, a pulse electric control valve 10 is installed on the branch pipe 3043, and a pulse electric control valve trigger switch 11 is installed in the shell 1. The pulse electric control valve trigger switch 11 is electrically connected to the pulse electric control valve 10. The pulse electric control valve trigger switch 11 is located between the fixed contact 2021 and the moving contact 2023. The use of the branch pipe 3043 can be controlled by the pulse electric control valve 10. Under normal use, the pulse electric control valve 10 is in a closed state, and only the heat pipe 3042 discharges air to the shell. Heat is dissipated inside the body 1. When the trigger component 202 performs the trigger operation, the elastic structure 2022 can control the movement of the movable contact 2023. When the movable contact 2023 moves, it can first contact the pulse electric control valve trigger switch 11, and then the pulse electric control valve 10 opens. The airflow can pass through the branch pipe 3043, and then the movable contact 2023 can contact the fixed contact 2021 to trigger the protection switch. At this time, the airflow discharged from the branch pipe 3043 can blow out the generated arc in time.

[0032] Furthermore, balancing holes 12 are opened on both sides of the shell 1, and a partition mesh 13 is installed in the balancing hole 12. The balancing hole 12 can facilitate the discharge of internal gas from the shell 1 to ensure internal air pressure balance, and the partition mesh 13 can prevent dust in the external air from entering the shell 1.

[0033] In the specific implementation, such as Figure 1 and Figure 4 As shown, a slot 4 is provided on the air intake shell 301, and a dust shield 302 is mounted in the slot 4. A detachable filter 5 is mounted inside the dust shield 302. The dust shield 302 is attached to the inner side of the air intake groove 6. The dust shield 302 and the detachable filter 5 can filter dust in the air, thereby preventing dust from entering the shell 1, thereby reducing internal heat dissipation and avoiding the generation of additional electric arcs.

[0034] Furthermore, an electric telescopic rod 7 is installed on the inner wall of the shell 1, and a control plate 8 is installed at the bottom of the dust shield 302. The control plate 8 is installed at the output end of the electric telescopic rod 7. The electric telescopic rod 7 can push the control plate 8 and the dust shield 302 outward, so that the detachable filter plate 5 can be easily replaced.

[0035] The standard parts used in the utility model can all be purchased on the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
