Description

Technical Field

[0001] The utility model relates to the technical field of electric mosquito swatters, in particular to a novel switch structure of an electric mosquito swatter. Background Art

[0002] Electric mosquito swatters, as commonly used small household appliances, are essential tools for killing mosquitoes in summer. Electric mosquito swatters are usually equipped with a main switch, which can be turned on and off to control the power. When the main switch is turned to the power-off position, the battery stops supplying power to the mosquito-killing network, but the mosquito-killing network will still have residual power for a period of time, which poses a safety hazard.

[0003] To solve the above problems, the Chinese utility model patent with authorization announcement number CN207444091U discloses an electric mosquito swatter, which has a control switch group arranged at the handle, the control switch group includes a first switch connected in series between the second power supply and the boost circuit, and a second switch connected in series between the boost circuit and the third discharge resistor, the installation direction of the second switch is opposite to the installation direction of the first switch, and an insulating rod is connected between the spring sheet of the first switch and the spring sheet of the second switch. When the second switch is closed, the insulating rod will open the first switch at the same time, thereby playing a role in eliminating residual electricity. This structural design mainly relies on the insulating rod to achieve transmission. Long-term use can easily lead to rigid fatigue of the insulating rod, resulting in bending and deformation of the rod body, which in turn affects the linkage reliability between the insulating rod and the first switch or the second switch. To this end, we propose a new switch structure for an electric mosquito swatter. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel switch structure for an electric mosquito swatter.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new switch structure of an electric mosquito swatter, comprising a toggle switch for being connected in series between a power supply and a boost circuit, and a normally closed micro switch for being connected in series with a discharge resistor, a PCB circuit board is stacked above the normally closed micro switch, the toggle switch is arranged on the PCB circuit board, a sliding dial key is connected between the toggle switch and the normally closed micro switch, the sliding dial key is horizontally slidably arranged on the handle housing, the sliding dial key is provided with a push plate portion, a card slot for accommodating the handle of the toggle switch is provided between the two push plate portions, one of the push plate portions is connected with a first convex rod portion for pressing the normally closed micro switch, and the other push plate portion is provided with a second convex rod portion, and a limit member for limiting the vertical movement of the sliding dial key is fixedly arranged on the PCB circuit board.

[0006] It is further explained that the limiting member includes a main body, a blocking portion, and an elastic buckle portion. The blocking portion is arranged at the lateral edge of the main body, the blocking portion abuts against the second protruding rod portion of the sliding dial key, and the elastic buckle portion is arranged at the longitudinal edge of the main body.

[0007] It is further explained that the handle shell includes an upper half shell and a lower half shell, the lower half shell is provided with a snap groove opening, and the elastic snap portion of the limiting member is snapped to the snap groove opening of the lower half shell.

[0008] To further illustrate, the elastic buckle portion of the limiting member is provided with two external prying convex teeth that are symmetrically arranged with each other.

[0009] It is further explained that a buckle tongue portion is provided at the buckle groove opening of the lower half shell, and when the elastic buckle portion of the limiting member is buckled at the buckle groove opening of the lower half shell, the buckle tongue portion is buckled between the two outer prying convex teeth.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model adopts the structural design of the sliding dial key to realize the simultaneous triggering of the toggle switch and the normally closed micro switch. Compared with the insulating rod in the prior art, the first convex rod portion of the sliding dial key can trigger the normally closed micro switch, and the first convex rod portion and the second convex rod portion can play a role similar to a reinforcing rib, so that the sliding dial key as a whole has a better rigid fatigue tolerance, and it is not easy to bend and deform, etc., which effectively ensures the reliability of the linkage between the toggle switch and the normally closed micro switch;

[0012] 2. The utility model adds a limiter for limiting the vertical movement of the sliding dial key, so that the sliding dial key can be directly tested by sliding horizontally without closing the upper and lower shells of the handle shell together, so that it can be directly checked which specific components cause the sliding dial key to be unable to slide smoothly, effectively improving the test efficiency.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Combined with Figure 1 To Attachment Figure 5 As shown, a novel switch structure of an electric mosquito swatter includes a toggle switch 10 for being connected in series between a power supply and a boost circuit, and a normally closed micro switch 20 for being connected in series with a discharge resistor. The toggle switch 10 plays a role equivalent to the first switch K1 of the Chinese utility model patent with the authorization announcement number CN207444091U, and the normally closed micro switch 20 plays a role equivalent to the second switch K2 in the patent. However, the first switch K1 and the second switch K2 are both micro switches, and are arranged opposite to each other and are linked to each other through an insulating rod.

[0021] Compared with the prior art, the toggle switch 10 of the utility model is specifically welded and arranged at the PCB circuit board 30, and the PCB circuit board 30 is stacked above the normally closed micro switch 20, and a sliding dial key 40 is connected and arranged between the toggle switch 10 and the normally closed micro switch 20. The sliding dial key 40 is horizontally slidably arranged at the handle housing, and the sliding dial key 40 is provided with a push plate portion 41, and a card slot 44 for accommodating the handle 11 of the toggle switch 10 is provided between the two push plate portions 41, wherein one of the push plate portions 41 is connected and provided with a first convex rod portion 42 for pressing the normally closed micro switch 20, and the other push plate portion 41 is provided with a second convex rod portion 43. The sliding dial key 40 of the utility model can be specifically applied to the handle housing of an electric mosquito swatter, and the sliding dial key 40 is provided with a card slot 44 for accommodating the handle 11 of the toggle switch 10 between the two push plate portions 41, and a first convex rod portion 42 for pressing the normally closed micro switch 20 is connected and arranged at one of the push plate portions 41. Compared with the insulating rod in the prior art, the first protruding rod portion 42 of the sliding dial key 40 can trigger the normally closed microswitch 20, and the first protruding rod portion 42 and the second protruding rod portion 43 can play a role similar to that of a reinforcing rib on the push plate portion 41. The sliding dial key 40 as a whole has better rigid fatigue tolerance and is not prone to bending and deformation, thereby effectively ensuring the reliability of the linkage between the toggle switch and the normally closed microswitch.

[0022] As attached Figure 1 As shown, when the sliding dial key 40 is located at the rightmost end of the sliding slot 613 of the handle housing, the toggle switch 10 is in a normally open state, the power supply and the boost circuit are in an open circuit state, and the electric mosquito swatter has not yet been powered on; and the normally closed microswitch 20 has not yet been triggered, the normally closed microswitch 20 is in a normally closed state, and the normally closed microswitch 20 and the discharge resistor are in a conductive state.

[0023] As attached Figure 2 As shown, when the sliding dial key 40 is located at the leftmost end of the sliding groove 613 of the handle housing, the sliding dial key 40 drives the toggle switch 10, and the toggle switch 10 is changed to a normally closed state, and the power supply and the boost circuit are in a state of passage, the electric mosquito swatter is energized, and can be directly used to electrocute mosquitoes; and, the button 21 at the normally closed microswitch 20 is pressed by the first protruding rod portion 42 of the sliding dial key 40, the normally closed microswitch 20 is triggered, the normally closed microswitch 20 is in a normally open state, and the normally closed microswitch 20 and the discharge resistor are in an open circuit state.

[0024] When using an electric mosquito swatter, Figure 2 As shown, the sliding dial key 40 needs to be slid to the leftmost end of the sliding notch 613 of the handle housing to power on the electric mosquito swatter. At this time, the normally closed micro switch 20 and the discharge resistor are in an open circuit state. Figure 1 As shown, the sliding dial key 40 is slid to the rightmost end of the sliding slot 613 of the handle shell to cut off the power to the mosquito swatter. At this time, the normally closed micro switch 20 and the discharge resistor are in a conductive state, and the discharge resistor can quickly eliminate the residual power of the mosquito swatter.

[0025] Since the handle housing specifically includes an upper half shell and a lower half shell 61, after installing the normally closed micro switch 20 and the PCB circuit board 30, it is necessary to further test whether the sliding dial key 40 can smoothly slide to trigger the toggle switch 10 and the normally closed micro switch 20. The existing electric mosquito swatter requires the upper half shell and the lower half shell 61 of the handle housing to be covered together before the sliding dial key 40 can be slid and tested. If it is tested that the sliding dial key 40 cannot smoothly slide to trigger the toggle switch 10 and the normally closed micro switch 20, the handle housing needs to be disassembled to check which parts have problems, which seriously affects the test efficiency.

[0026] To this end, combined with the Figure 1 and attached Figure 3As shown, a limiter 50 is fixedly arranged at the PCB circuit board 30. The limiter 50 can be directly locked above the PCB circuit board 30 and play a role in limiting the vertical movement of the sliding dial key 40. During the test, the sliding dial key 40 can be directly slid horizontally to test without closing the upper half shell and the lower half shell 61 of the handle housing together, so that which components cause the sliding dial key 40 to be unable to slide smoothly can be directly checked, which effectively improves the test efficiency.

[0027] As attached Figure 3 As shown, the limiting member 50 includes a main body 51, a blocking portion 52, and an elastic buckle portion 53. The blocking portion 52 is arranged at the transverse edge of the main body 51, and the blocking portion 52 abuts against the second protruding rod portion 43 of the sliding dial key 40. The elastic buckle portion 53 is arranged at the longitudinal edge of the main body 51. A buckle groove 611 is arranged at the lower half shell 61. When the limiting member 50 is installed, the elastic buckle portion 53 of the limiting member 50 can be directly buckled at the buckle groove 611 of the lower half shell 61.

[0028] The elastic buckle portion 53 of the stopper 50 is provided with two symmetrically arranged outer prying convex teeth 54. A buckle tongue portion 612 is provided at the buckle groove 611 of the lower half shell 61. When the elastic buckle portion 53 of the stopper 50 is buckled at the buckle groove 611 of the lower half shell 61, the buckle tongue portion 612 is buckled between the two outer prying convex teeth 54. The outer prying convex teeth 54 of the stopper 50 can be pried up by a flat-blade screwdriver, so that the staff can directly remove the stopper 50 from the buckle groove 611 of the lower half shell 61.
