Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly relates to a control switch with a protection function and an electric mosquito swatter. Background Art

[0002] An electric mosquito swatter is a small household appliance product. The electronic high-voltage mosquito swatter is generally popular among people for its practicality, convenience, good mosquito-killing (flies or moths, etc.) effect, no chemical pollution, safety and hygiene, etc. It has gradually become an indispensable tool for killing insects in summer and a best-selling small household appliance product in summer. The switch contact terminals are prone to oxidation problems during long-term use. Especially when using the electric mosquito swatter in a humid area, water vapor in the air will react chemically with the surface of the contact terminals to form oxides. These oxides will cover the surface of the contact terminals, increasing the resistance of the contact terminals, resulting in the inability of the current to pass smoothly, thus causing poor contact and further affecting the normal operation of the electric mosquito swatter. Summary of the Invention

[0003] The purpose of the present invention is to provide a control switch with a protection function and an electric mosquito swatter, which solves the problem that the surface of the contact terminals of the existing control switch for the electric mosquito swatter will be oxidized to generate oxides, increasing the resistance of the contact terminals, resulting in the inability of the current to pass smoothly, thus causing poor contact and further affecting the normal operation of the electric mosquito swatter.

[0004] The present invention solves the above technical problems through the following technical solutions. The present invention includes:

[0010] An elastic contact mechanism, which is arranged inside the protective shell and is electrically connected to the power connection mechanism. When the protective shell rotates to correspond to the first contact terminal, the partition mechanism is pushed to the open state and the elastic contact mechanism is electrically connected to the first contact terminal to realize power-on;

A pull rope is fixed to the outside of the power connection mechanism. The outer end of the pull rope bypasses the guiding plate and is connected to the second electrical contact terminal;

[0019] When the elastic electrical contact mechanism is electrically connected to the first electrical contact terminal, the pull rope is in a taut state, and the second electrical contact terminal extends out of the elongated portion of the protective housing due to the action of the second spring; when the elastic electrical contact mechanism is docked with the pressing plate, the pull rope is in a bent state, and the second electrical contact terminal retracts into the elongated portion of the protective housing due to the restriction of the pull rope.

[0020] Preferably, the pressing plate has a sealing arc portion and a guiding arc portion, and the guiding arc portion is located on the side close to the first electrical contact terminal;

In the present invention, when the switch is switched to the off state, the second electric shock terminal can automatically retract into the elongated portion without being pushed into the elongated portion by the pressing plate, thereby eliminating the resistance between the second electric shock terminal and the pressing plate and reducing the torque during the rotation of the protective shell.

DETAILED DESCRIPTION

[0035] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The elastic electrical contact mechanism is arranged inside the protective shell and is electrically connected to the power connection mechanism. The elastic electrical contact mechanism includes a fixed frame 84 fixed inside the elongated portion 33. A second spring 83 and a second electrical contact terminal 82 are sequentially arranged outside the fixed frame 84. The second spring 83 gives the second electrical contact terminal 82 a force to move outward. The second electrical contact terminal 82 is adapted to the cross-section of the elongated portion 33 to ensure the stability of the second electrical contact terminal 82 during sliding. The second electrical contact terminal 82 is electrically connected to the conductive block 61 of the power connection mechanism through a conductive wire 81.

[0046] An arc-shaped groove 51 is formed on the outside of the first electrical contact terminal 5. The outside of the second electrical contact terminal 82 has an arc-shaped portion adapted to the arc-shaped groove 51. When the elongated portion 33 is butted against the first electrical contact terminal 5, the second electrical contact terminal 82 will contact the first electrical contact terminal 5 due to the force of the second spring 83, and the arc-shaped portion of the second electrical contact terminal 82 is coupled with the arc-shaped groove 51 to ensure the stability of the electrical connection between the first electrical contact terminal 5 and the second electrical contact terminal 82.

[0047] 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 electrical contact mechanism and the first electrical contact terminal 5; the power mechanism 2 includes a rack 21 slidably installed on the shell and a half gear 24 arranged outside the disc portion 32 of the protective shell, and the rack 21 is meshed with the half gear 24. The sliding track of the rack 21 is perpendicular to the handle of the electric mosquito swatter. In this embodiment, the driving portion 23 is a pressing type. A third spring 22 is arranged 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). A driving portion 23 is arranged on the outside of the rack 21. In this embodiment, the driving portion 23 is a pressing block made of rubber to increase the comfort of the user.

[0048] When in need of use, manually press the driving part 23, so that the rack 21 moves inward for the first process, and compresses the third spring 22. The cooperation between the rack 21 and the half gear 24 will drive the protective shell to rotate by an angle of the first process. During this process, the long-shaped part 33 will gradually rotate towards the side of the first contact terminal 5. The second contact terminal 82 will move outward due to the acting force of the second spring 83, and the second contact terminal 82 is always in contact with the pressing plate 35. When the long-shaped part 33 rotates to correspond to the guiding arc part 352, the second contact terminal 82 will gradually extend out of the long-shaped part 33. When the second contact terminal 82 contacts the moving plate 42, it will push the moving plate 42 towards the side away from the pressing plate 35, and compress the first spring 41 until the first contact terminal 5 corresponds to the second contact terminal 82. The second contact terminal 82 will, under the acting force of the second spring 83, have a certain resistance in the cooperation between the arc part of the second contact terminal 82 and the arc-shaped groove 51, and this resistance can counteract 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. Therefore, balance can be maintained, enabling the second contact terminal 82 to be stably connected to the first contact terminal 5, and power-on can be achieved. When power-off is needed, manually press the driving part 23, so that the rack 21 moves inward for the second process, and further compresses the third spring 22. The cooperation between the rack 21 and the half gear 24 will drive the protective shell to rotate by an angle of the second process. At this time, the second contact terminal 82 will be released from the limitation of the arc-shaped groove 51, and the second contact terminal 82 moves to contact one side of the moving plate 42. Then release the driving part 23. Since the second contact terminal 82 is not restricted at this time, it will flip under the torque acting force of the third spring 22 until the second contact terminal 82 contacts the protruding part 43, and the moving plate 42 will also move under the acting force of the second contact terminal 82 and the acting force of the first spring 41 to cover the first contact terminal 5. Since the protruding part 43 is small, it cannot restrict the second contact terminal 82, and the second contact terminal 82 will continue to flip under the acting force of the third spring 22. The second contact terminal 82 will also gradually retract into the long-shaped part 33 under the extrusion of the guiding arc part 352 until the long-shaped part 33 corresponds to the sealing arc part 351, sealing the protective shell, and power-off is completed.

[0049] Embodiment 2 is a further optimization based on Embodiment 1. The same parts as the foregoing technical solutions will not be described herein again. As Figure 3 shown, in order to better implement the present invention, the following setting method is particularly adopted:

[0050] A guiding plate 36 fixed to the power connection mechanism is arranged inside the protective shell, and the guiding plate 36 is located on the side of the power connection mechanism relative to the first contact terminal 5. A pulling rope 31 is fixed to the outside of the power connection mechanism. The outer end of the pulling rope 31 bypasses the guiding plate 36 and is connected to the second contact terminal 82.

[0051] When the elastic electrical contact mechanism is electrically connected to the first electrical contact terminal 5, at this time, the elongated portion 33 of the protective housing corresponds to the guide plate 36. Therefore, the pull rope 31 is in a straightened state and will not restrict the second electrical contact terminal 82. Due to the acting force of the second spring 83, the second electrical contact terminal 82 extends out of the elongated portion 33 of the protective housing; when the elastic electrical contact mechanism is butted against the pressing plate 35, the guide plate 36 does not correspond to the elongated portion 33. Therefore, the pull rope 31 will bypass the guide plate 36, and the pull rope 31 is in a bent state, increasing the length of the path of the pull rope 31. Therefore, the second electrical contact terminal 82 retracts into the elongated portion 33 of the protective housing due to the restriction of the pull rope 31.

[0052] In this embodiment, when the switch is switched to the off state, the second electrical contact terminal 82 can automatically retract into the elongated portion 33 without being pushed by the pressing plate 35 into the elongated portion 33, thereby eliminating the resistance between the second electrical contact terminal 82 and the pressing plate 35 and reducing the torque when the protective housing rotates.

[0053] Embodiment 3 is a further optimization based on Embodiment 1. The same parts as the foregoing technical solutions will not be described herein again. As Figure 4 shown, in order to better implement the present invention, the following setting method is particularly adopted:

[0054] In this embodiment, the driving part 23 is a push type, the sliding track of the rack 21 is parallel to the handle of the electric mosquito swatter, the whole driving part 23 is outside the housing, and a long waist hole 25 is provided on the housing. No matter where the driving part 23 moves to, the driving part 23 can cover the entire section of the long waist hole 25 to ensure the sealing of the housing.

[0055] Embodiment 4, an electric mosquito swatter, as Figure 5 shown, includes the control switch with a protection function in the above embodiment, and the control switch 100 is embedded and installed at the handle of the electric mosquito swatter.

[0056] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
