DETAILED DESCRIPTION

[0019] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0020] Embodiment 1: This embodiment provides a technical solution: a control switch with a protection function, such as Figures 1 to 4 As shown, it includes a shell, a first electric contact terminal 5, a partition mechanism, a power connection mechanism, a protective shell, an elastic electric contact mechanism and a power mechanism 2. The first electric contact terminal 5, the partition mechanism, the power connection mechanism, the protective shell, the elastic electric contact mechanism and the power mechanism 2 are integrated in the shell.

[0021] The shell is detachably arranged so as to facilitate disassembly and installation of the components inside it. The shell comprises an outer shell 11 and a cover plate 12 which is screwed to the outer shell 11. A sealing strip may be arranged between the outer shell 11 and the cover plate 12 to increase the sealing of the connection between the two and avoid the entry of water vapor and oxygen as much as possible.

[0022] The first electric shock terminal 5 is installed on the inner wall of one side of the shell, and a first external connection part 52 electrically connected to the first electric shock terminal 5 is provided on the outer side of the shell. The first external connection part 52 is electrically connected to the mesh of the electric mosquito swatter through an electric wire. The first external connection part 52 is a wiring terminal or a welding terminal. The wiring terminal is connected to the electric wire in a detachable manner, and the welding terminal is connected to the electric wire by soldering.

[0023] The partition mechanism is arranged inside the shell, which is used to isolate the first electric contact terminal 5 from the outside world, and the partition mechanism has a sealed state and an open state. When the switch is powered off, the partition mechanism is in a sealed state, which can prevent the first electric contact terminal 5 from chemically reacting with water vapor in the air to form oxides. When the switch is powered on, the partition mechanism is in an open state, that is, it is electrically connected to the elastic electric contact mechanism. In summary, since the electric mosquito swatter is idle most of the time in daily life, the partition mechanism can prevent the first electric contact terminal 5 from being oxidized during this time, thereby greatly slowing down the oxidation of the first electric contact terminal 5 and improving its service life.

[0024] The isolating mechanism includes a sealing frame 44 arranged on the periphery of the first electric contact terminal 5, one side of the sealing frame 44 is fixed to the shell, and the other side has an open port, and the port of the sealing frame 44 is installed with a movable plate 42 slidably arranged on the inner wall of the shell, when the movable plate 42 slides to correspond to the sealing frame 44, it blocks the port of the sealing frame 44, and the sealing frame 44 and the movable plate 42 cooperate to achieve the isolation of the first electric contact terminal 5 from the outside world, and a first spring 41 is installed on the side of the movable plate 42 away from the extrusion plate 35, and the first spring 41 gives the movable plate 42 a force to move toward the port of the sealing frame 44 and block the port of the sealing frame 44. In order to increase the stability of the installation of the first spring 41, the end of the movable plate 42 has a widening portion, and the outer side of the end of the movable plate 42 close to the extrusion plate 35 has a protrusion 43.

[0025] The sliding method of the movable plate 42 can be as follows: two corresponding sliding grooves are opened on the inner wall of the shell, and the length direction of the sliding groove is parallel to and close to the port of the sealing frame 44. The two sides of the movable plate 42 are respectively slidably set in the two sliding grooves, and the length of the sliding groove has a certain limit, and the movable plate 42 will not exceed the range of the first electric contact terminal 5.

[0026] The power connection mechanism is installed through the shell, and is used to be electrically connected to an external power source; the power connection mechanism includes an outer tube 62 fixed through the shell, a conductive block 61 is arranged inside the outer tube 62, and a second external connection part 63 electrically connected to the conductive block 61 is arranged on the outside of the shell. The second external connection part 63 has the same structure as the first external connection part 52, and both can adopt wiring terminals or welding terminals.

[0027] The protective shell is rotatably installed on the power connection mechanism. The protective shell includes a disc portion 32 rotatably connected to the outer tube 62 of the power connection mechanism and an elongated portion 33 connected to the disc portion 32. A sealing ring is provided at the connection between the disc portion 32 and the outer tube 62 to reduce the external water vapor from entering the protective shell as much as possible. A rubber pad 34 is provided at the port of the elongated portion 33.

[0028] An extrusion plate 35 is fixed in the shell, and one end of the extrusion plate 35 corresponds to the first electric contact terminal 5. The extrusion plate 35 is used to seal the port of the protective shell when the protective shell is rotated to a specified angle. The extrusion plate 35 has a sealing arc portion 351 and a guiding arc portion 352, and the guiding arc portion 352 is located on the side close to the first electric contact terminal 5. The movement trajectory 7 of the end of the elongated portion 33 of the protective shell coincides with the sealing arc portion 351. When the elongated portion 33 of the protective shell rotates to correspond to the sealing arc portion 351, the sealing arc portion 351 is pressed against the rubber pad 34 at the end of the elongated portion 33, so that the rubber pad 34 is squeezed to ensure the sealing between the sealing arc portion 351 and the elongated portion 33 to prevent water vapor from entering the interior of the protective shell. There is an angle between the movement trajectory 7 of the end of the elongated portion 33 of the protective shell and the guiding arc portion 352.

[0029] The elastic electric shock mechanism is arranged in the protective shell and is electrically connected to the power connection mechanism. The elastic electric shock mechanism includes a fixed frame 84 fixed inside the elongated portion 33. The outer side of the fixed frame 84 is sequentially provided with a second spring 83 and a second electric shock terminal 82. The second spring 83 applies a force to the second electric shock terminal 82 to move outward. The cross-section of the second electric shock terminal 82 is adapted to the cross-section of the elongated portion 33 to ensure the stability of the second electric shock terminal 82 when sliding. The second electric shock terminal 82 is electrically connected to the conductive block 61 of the power connection mechanism through a conductive wire 81.

[0030] An arc-shaped groove 51 is provided on the outer side of the first contact terminal 5, and an arc-shaped portion adapted to the arc-shaped groove 51 is provided on the outer side of the second contact terminal 82. When the elongated portion 33 is docked with the first contact terminal 5, the second contact terminal 82 will contact the first contact terminal 5 due to the action of the second spring 83, and the arc-shaped portion of the second contact terminal 82 is coupled with the arc-shaped groove 51 to ensure the stability of the electrical connection between the first contact terminal 5 and the second contact terminal 82.

[0031] The power mechanism 2 is used to control the rotation of the protective shell to realize the switching of the electrical connection between the elastic electric shock mechanism and the first electric shock terminal 5; the power mechanism 2 includes a rack 21 slidably mounted on the shell and a half gear 24 arranged on the outside of the disc portion 32 of the protective shell, and the rack 21 is meshed and connected with the half gear 24, and the sliding trajectory of the rack 21 is perpendicular to the handle of the electric mosquito swatter. The driving part 23 in this embodiment is a press type, and a third spring 22 is provided on one side of the rack 21. The third spring 22 gives the rack 21 a force to move along its length direction (in this embodiment, the force of the third spring 22 pushes the rack 21 outward), and a driving part 23 is provided on the outside of the rack 21. The driving part 23 in this embodiment is a rubber push block to increase the comfort of the user.

[0032] When it is needed, the driving part 23 is manually pressed to make the rack 21 move inwardly by the first process and compress the third spring 22. The cooperation between the rack 21 and the half gear 24 will drive the protective shell to rotate by the first process. In this process, the elongated part 33 will gradually rotate to one side of the first electric contact terminal 5, and the second electric contact terminal 82 will move outward due to the force of the second spring 83, and the second electric contact terminal 82 will always be in contact with the extrusion plate 35. When the elongated part 33 rotates to correspond to the guide arc part 352, the second electric contact terminal 82 will gradually extend out of the elongated part. When the second electric contact terminal 82 contacts the movable plate 42, the movable plate 42 will be pushed to the side away from the extrusion plate 35, and the first spring 41 will be compressed until the first electric contact terminal 5 corresponds to the second electric contact terminal 82. Under the action of the second spring 83, the arc portion of the second electric contact terminal 82 cooperates with the arc groove 51, and there is a certain resistance between the two. The resistance can resist the sum of the torque of the third spring 22 on the protective shell and the torque of the first spring 41 on the protective shell, so that the balance can be maintained, so that the second electric contact terminal 82 When the first electric contact terminal 5 is stably connected, power can be turned on; when power needs to be turned off, the driving part 23 is manually pressed to make the rack 21 move inward by the second process, and the third spring 22 is further compressed. The cooperation between the rack 21 and the half gear 24 will drive the protective shell to rotate by the second process. At this time, the second electric contact terminal 82 will be freed from the restriction of the arc groove 51, and the second electric contact terminal 82 will move to contact one side of the movable plate 42. Then the driving part 23 is released. Since the second electric contact terminal 82 is not restricted at this time, it will flip under the torque force of the third spring 22. , until the second electric contact terminal 82 contacts the raised portion 43, and the movable plate 42 will also move to cover the first electric contact terminal 5 under the action of the second electric contact terminal 82 and the action of the first spring 41. Since the raised portion 43 is small, it cannot restrict the second electric contact terminal 82, and the second electric contact terminal 82 will continue to flip under the action of the third spring 22. The second electric contact terminal 82 will also gradually retract into the elongated portion 33 under the extrusion of the guiding arc portion 352, until the elongated portion 33 corresponds to the sealing arc portion 351, sealing the protective shell, and completing the power off.

[0033] Embodiment 2: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solution will not be repeated here. Figure 3 As shown, in order to better implement the present invention, the following configuration is particularly adopted: A guide plate 36 fixed to the power connection mechanism is provided in the protective shell, and the guide plate 36 is located on one side of the power connection mechanism relative to the first contact terminal 5. A pull rope 31 is fixed to the outside of the power connection mechanism, and the outer end of the pull rope 31 passes around the guide plate 36 and is connected to the second contact terminal 82.

[0034] When the elastic electric shock mechanism is electrically connected to the first electric shock terminal 5, at this time, the elongated portion 33 and the guide plate 36 of the protective shell correspond, so the pull rope 31 is in a straight state and will not restrict the second electric shock terminal 82. The second electric shock terminal 82 extends out of the elongated portion 33 of the protective shell due to the action force of the second spring 83; when the elastic electric shock mechanism is docked with the extrusion plate 35, the guide plate 36 and the elongated portion 33 do not correspond, so the pull rope 31 will bypass the guide plate 36, and the pull rope 31 is in a bent state, which increases the length of the pull rope 31 path. Therefore, the second electric shock terminal 82 retracts into the elongated portion 33 of the protective shell due to the restriction of the pull rope 31.

[0035] In this embodiment, when the switch is switched to the off state, the second contact terminal 82 can automatically retract into the elongated portion 33 without being pushed into the elongated portion 33 by the extrusion plate 35, thereby eliminating the resistance between the second contact terminal 82 and the extrusion plate 35 and reducing the torque when the protective shell rotates.

[0036] Embodiment 3: This embodiment is further optimized on the basis of embodiment 1, and the same parts as the above technical solutions will not be repeated here. Figure 4 As shown, in order to better implement the present invention, the following configuration is particularly adopted: In this embodiment, the driving part 23 is a push type, the sliding trajectory of the rack 21 is parallel to the handle of the electric mosquito swatter, the driving part 23 is entirely on the outside of the shell, and a long waist hole 25 is provided on the shell. No matter where the driving part 23 is moved to, the driving part 23 can cover the entire long waist hole 25 to ensure the sealing of the shell.

[0037] Embodiment 4, an electric mosquito swatter, such as Figure 5 As shown, it includes the control switch with protection function of the above embodiment, and the control switch 100 is embedded in the handle of the electric mosquito swatter.
