Description

Technical Field

[0001] The utility model relates to household appliances, in particular to an electric mosquito swatter with a bendable electric grid. Background Art

[0002] The electric mosquito swatter is a small household appliance. Its principle is that the direct current generated by the battery can form a potential difference of about 2000V between the cathode and anode grids after being boosted by the circuit. At this time, when the grid is close to mosquitoes that are resting on the wall or other surfaces, the mosquitoes will be frightened and crash into the grid. The high voltage electricity will break through the air near the mosquitoes, forming an arc discharge between the positive and negative poles accompanied by flashes and crackling explosions, thereby killing the mosquitoes. Although the voltage between the positive and negative poles of the electric mosquito swatter is very high, the single discharge current is very small, and there is no danger even if it is accidentally touched by a person when it is powered on. Therefore, the electric mosquito swatter has the advantages of being convenient, safe, hygienic, and chemically pollution-free to kill mosquitoes.

[0003] However, existing electric mosquito swatters have the following disadvantages: First, mosquitoes like to stay on irregular surfaces such as corners of walls, table corners, and tubular objects. At this time, it is difficult to completely cover the mosquitoes with the electric grid when using traditional electric mosquito swatters. There will be certain blind spots covered by the electric grid, and mosquitoes are likely to escape from the blind spots covered by the electric grid. Second, when catching mosquitoes that are resting on the ceiling, it is often impossible to reach them with just your arms. At this time, you need to stand on a table or chair and then press the entire electric mosquito swatter horizontally against the ceiling, which is very inconvenient.

[0004] Existing foldable electric mosquito swatters all fold the swatter rod and the swatter surface to achieve the purpose of reducing the volume and facilitating storage, such as the foldable electric mosquito swatter disclosed in patent number CN202022320771.2. However, it does not make the electric grid more closely fit the surface of irregular objects, increase the effective coverage area of ​​the electric grid on the irregular surface, and improve the success rate of catching mosquitoes.

A protruding shaft 32 is disposed on the left side of the front surface of the second racket face shell connecting section 31 .

[0041] Furthermore, the structural details of the first face shell connecting section 21 are as follows: the outer contour of the first face shell connecting section 21 is semicircular on the left side and rectangular in the middle section, the rightmost end is connected to the first face shell 2, the thickness is half of the first face shell 2, and the connection position with the first face shell 2 is located outside the first face shell 2, and the rear surface of the first face shell connecting section 21 is coplanar with the outer side of the first face shell 2.

The front surface of the first racket face shell connecting section 21 is provided with seven grooves 22, and the grooves 22 are arranged in a circular pattern with the center of the stepped hole as the center, and the spacing is 45 degrees.

[0042] Furthermore, a rotating shaft 24 is inserted into the stepped hole 23 of the first face shell connecting section 21, and the rotating shaft 24 is inserted from the rear surface of the first face shell connecting section 21 and extends to the outside of its front surface and inserted into the stepped hole 23 of the second face shell connecting section 31. The first face shell connecting section 21 and the second face shell connecting section 31 are in contact with each other in a front-to-front manner, and the convex shaft 32 on the second face shell connecting section 31 is inserted into the groove 22 of the first face shell connecting section 21. A compression spring 33, a convex shaft 32 and an insulating button 34 are sequentially placed in the stepped hole 22 of the second face shell connecting section 31, one end of the compression spring 33 is in contact with the second-level platform 231 of the stepped hole, and the other end is in contact with the convex shaft 32, and the insulating button external thread 341 on the outside of the insulating button 34 is screwed into the internal thread 36 on the stepped hole 23 of the second face shell connecting section 31. The purpose of installing the insulating button is to separate the cathode connecting shaft 45 from the compression spring 33 to prevent leakage through the compression spring 33 made of metal.

[0043] Furthermore, a rotating shaft pin hole 241 is provided at the bottom of the rotating shaft 24, and a fixing pin 351 is provided at the top of the fixing pin 35. The fixing pin 351 is inserted into the rotating shaft pin hole 241 and fixedly connected by gluing or the like. The purpose of bonding is to make the rotating shaft 24 and the fixing pin 35 become a whole, and cannot be displaced or rotated relative to each other.

[0044] It is worth mentioning that the above-mentioned descriptions of the positions such as “front surface”, “rear surface”, and “left side” in the first racket face shell connecting section 21 and the second racket face shell connecting section 31 are based on Figure 3-4 The "interior" and "inner side" of the first face shell 2 and the second face shell 3 refer to the side where the power grid is installed, and vice versa.

[0045] Furthermore, the specific structural details of the power grid part are as follows: the first power grid cathode 43 is symmetrically provided with two layers of first power grid anodes 41 on both sides, and similarly, the second power grid cathode 44 is symmetrically provided with two layers of second power grid anodes 42 on both sides. The edges of the first power grid anode 41 and the second power grid anode 42 are respectively provided with power grid anode hard edges 49, and the anode conductive spring 46 is located above the first power grid anode 41 and the second power grid anode 42, and is fixed on the first power grid anode 41 and the second power grid anode 42 through four groups of copper wires 47, wherein two groups of copper wires 47 fix the anode conductive spring 46 on the power grid anode hard edges 49, and the other two groups of copper wires 47 fix the two ends of the anode conductive spring 46 on the first power grid anode 41 and the second power grid anode 42 respectively. A flexible insulator 481 is sandwiched between the first grid anode 41, the second grid anode 42 and the first grid cathode 43, the second grid cathode 44. The flexible insulator 481 is located at the connection between the first grid anode 41, the second grid anode 41 and the first grid cathode 43, the second grid cathode 44, and is located directly below the anode conductive spring 46. A rigid support insulator 482 is provided between the first grid anode 41 and the first grid cathode 43. One end of the rigid support insulator 482 is connected to the first grid anode 41, and the other end extends toward the first grid cathode 43 and passes through the hole on the first grid cathode 43 to contact the first grid anode 41 on the other side. Similarly, a rigid support insulator 482 is also provided between the second grid anode 42 and the second grid cathode 44 in the same manner. The installation position of the rigid support insulator 482 is located directly below the two ends of the anode conductive spring 46, and is arranged in a straight line with the flexible insulator 481.

[0046] The purpose of setting the flexible insulator 481 is to prevent a short circuit from occurring at the junction of the anode conductive spring 46 and the first grid cathode 43 and the second grid cathode 44 when the grid is bent. The purpose of setting the grid anode hard edge 49 is to facilitate the use of copper wire 47 to fix the anode conductive spring 46 on the first grid anode 41 and the second grid anode 42, and to strengthen the local strength of the first grid anode 41 and the second grid anode 42, so as to prevent the first grid anode 41 and the second grid anode 42 from being deformed by the tensile stress or compressive stress of the anode conductive spring 46 when the grid is bent. Similarly, the purpose of setting the rigid support insulator 482 is that when the mosquito swatter grid is bent, the tensile stress or compressive stress at both ends of the anode conductive spring 46 is the strongest, and the rigid support insulator 482 can play a role in supporting the grid and maintaining the distance between the first grid anode 41 and the first grid cathode 43 (or the second grid anode 42 and the second grid cathode 44), so as to prevent a short circuit caused by grid deformation.

[0047] Furthermore, the cathode connecting shaft 45 is a hard spiral structure, the pitch of the spiral on the cathode connecting shaft 45 is equal to the mesh spacing of the first grid cathode 43 and the second grid cathode 44, and the spiral on the cathode connecting shaft 45 passes through each mesh on the edge of the first grid cathode 43 and the second grid cathode 44 one by one. When the grid is bent, the first grid cathode 43 and the second grid cathode 44 can rotate around the cathode connecting shaft 45. The cathode connecting shaft 45 is made of non-conductive materials such as non-metals because it is found through experiments that when the grid is bent, the first grid cathode 43, the second grid cathode 44 and the cathode connecting shaft 45 are sometimes not completely fitted, and there will be a small gap. At this time, if the cathode connecting shaft 45 is made of conductive material, arc discharge will occur when the mosquito swatter is working, resulting in the cathode connecting shaft 45 and the local position of the first grid cathode 43 and the second grid cathode 44 being welded into a whole, so that the grid cannot be bent, affecting the continued use of the electric mosquito swatter. To solve this problem, a solution is adopted in which parallel wires are led out from the boost circuit system 5 to supply power to the first grid cathode 43 and the second grid cathode 44 respectively, and the cathode connecting shaft 45 is made of non-conductive material.

[0048] Furthermore, the ratio of the diameter of the semicircular head of the first racket face shell connecting section 21 and the second racket face shell connecting section 31 to the side length of the middle section rectangle should be less than 2(√2-1):1, the purpose of which is to prevent the first racket face shell connecting section 21 and the second racket face shell connecting section 31 from colliding and getting stuck when the electric mosquito swatter is folded to 135 degrees. From a mathematical point of view, the semicircular head diameter is set to D, and the side length of the middle section rectangle is set to L. The sufficient but not necessary condition to prevent the electric mosquito swatter from getting stuck when it is folded to 135 degrees is that the L side on the first racket face shell connecting section 21 and the L side on the second racket face shell connecting section 31 are just connected at this point, as shown in the figure. Fig.16 As shown. It can be seen that the L side on the first racket face shell connecting section 21 and the L side on the second racket face shell connecting section 31 form an angle of 45°, and it is symmetrically cut along its angle bisector to obtain a right triangle with a minimum angle of 22.5°, and the length of one right angle side is L, and the length of the other right angle side is 0.5D (the radius of the semicircle of the head). According to the triangle sine formula, tan22.5°≥0.5D / L can be obtained, and √2-1≥D / 2L can be deduced. Finally, D: L≤2√2-2≈0.83 is derived.

[0049] Furthermore, the cathode connecting shaft 45 is coaxial with the rotating shaft 24, and the stepped hole 23 on the second face shell connecting section 31 is coaxial with the stepped hole 23 on the first face shell connecting section 21. The purpose of the coaxiality is to prevent the power grid from being twisted and damaged during the rotation process.

[0050] Furthermore, a battery box 6 and a boost circuit system 5 are installed inside the racket 1.

[0051] It is worth noting that the entire electric mosquito swatter is powered by the battery box 6 and the boost circuit system 5 increases the voltage. Since the boost circuit is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0052] Working principle of the shell part: Under the initial condition, the convex shaft 32 on the second racket face shell connecting section 31 is inserted into the groove 22 (one of the seven grooves) on the first racket face shell connecting section 21, and the compression spring 33 is in a compressed state, giving the second racket face shell connecting section 31 an upward thrust, forcing the convex shaft 32 on the second racket face shell connecting section 31 to be inserted into the groove 22 on the first racket face shell connecting section 21 for fixing, and the racket face of the electric mosquito swatter is in a locked state. When it is necessary to bend the power grid, one hand grasps the handle 25 and the other hand grasps the racket rod 1, driving the first racket face shell 2 and the second racket face shell 3 to rotate with the rotating shaft 24 as the axis, and at this time, a torque will be formed between the first racket face shell connecting section 21 and the second racket face shell connecting section 31. Under the action of the moment, the groove 22 and the convex shaft 32, which were originally inserted together, are subjected to a horizontal shear force. Because the groove 22 and the top of the convex shaft 32 are arc surfaces, the horizontal shear force will generate a pair of vertical force components when acting on the arc surface, and the directions of the forces are opposite. Under the joint action of the horizontal shear force and the vertical force component, the groove 22 and the convex shaft 32 slide relatively along the top arc surface, and the distance between the groove 22 and the convex shaft 32 increases until the convex shaft 32 is disengaged from the groove 22, and the compression spring 33 is further compressed. At this time, the second racket face shell connecting section 31 and the first racket face shell connecting section 21 are separated from each other and can rotate freely with the rotating shaft 24 as the axis, and the locking state is released. When the second face shell 3 and the first face shell 2 are rotated, the upper surface of the convex shaft 32 moves against the lower surface of the first face shell connecting section 21. When it is turned to the required position, the elastic potential energy of the compression spring 33 is released, and the convex shaft 32 on the second face shell connecting section 31 is pushed into the groove 22, and the relative position between the first face shell 2 and the second face shell 3 is locked again.

[0053] Working principle of the power grid: initial conditions such as Figure 5 As shown, at this time, the first grid anode 41 and the second grid anode 42 are in line, the first grid cathode 43 and the second grid cathode 44 are in line, and the anode conductive spring 46 fixed on the first grid anode 41 and the second grid anode 42 is in an untensioned state. When the grid needs to be bent, the rotation between the first racket face shell 2 and the second racket face shell 3 will drive the first grid anode 41, the first grid cathode 43, the second grid anode 42, and the second grid cathode 44 to rotate together; specifically, Fig.12As shown, the upper anode conductive spring 46 is pulled up at the section between the two pairs of anode grid hard edges 49, and the lower anode conductive spring 46 is compressed at the section between the two pairs of anode grid hard edges 49, while the two ends of the anode conductive spring 46 appear to have not changed. This is because when the grid is bent, the two ends of the anode conductive spring 46 (copper wire 47 to the anode grid hard edge 49) will be subjected to strong tensile stress or compressive stress, so the anode conductive spring 46 needs to have a longer length and be fixed to the first grid anode 41 and the second grid anode 42 with four groups of copper wires 47. In addition, when the power grid is bent, the upper anode conductive spring 46 between the two pairs of anode power grid hard edges 49 is pulled up, and the distance between the upper anode conductive spring 46 and the cathode connecting shaft 45 is shortened because the spring is tightened. Similarly, the lower anode conductive spring 46 between the two pairs of anode power grid hard edges 49 is compressed and bulges toward the cathode connecting shaft 45. Therefore, the anode conductive spring 46 is separated from the cathode connecting shaft 45 by the flexible insulator 481 to prevent the anode conductive spring 46 and the cathode connecting shaft 45 from being too close to each other and breaking through the air to cause a short circuit when power is turned on. When the power grid needs to be reset, the groove 22 and the convex shaft 32 only need to be adjusted to the unlocking position. At this time, the upper anode conductive spring 46 pulled up and the lower anode conductive spring 46 compressed rebound to the original position under the action of elastic potential energy, and the electric mosquito swatter power grid and the shell are automatically reset. When supplying power, the positive circuit directly supplies power to the second grid anode 42 and can be conducted to the first grid anode 41 through the anode conductive spring 46; while the negative circuit needs to supply power to the first grid cathode 43 and the second grid cathode 44 respectively.

[0054] The technical effects of the present invention are described below by means of specific embodiments:

[0055] To facilitate the description of the relative positional relationship between the convex shaft 32 and the grooves 22 when the power grid is folded, the seven grooves 22 are named ag in a counterclockwise order.

[0056] Embodiment 1:

[0057] This solution folds the electric net 90 degrees and can be used to catch mosquitoes at table corners and other locations. Figure 10-12 As shown. Under the initial condition, the convex shaft 32 on the second racket face shell connecting section 31 is inserted into the groove 22 (numbered d) on the first racket face shell connecting section 21. When the electric grid needs to be bent, one hand grasps the handle 25 and the other hand grasps the racket bar 1, and the first racket face shell 2 is rotated 90° counterclockwise around the rotation axis 24. At this time, the elastic potential energy of the compression spring 33 is released, and the convex shaft 32 on the second racket face shell connecting section 31 is pushed into the groove 22 (numbered b), and the relative position between the first racket face shell 2 and the second racket face shell 3 is locked again.

[0058] Embodiment 2:

[0059] This solution folds the grid 45 degrees and can be used to capture mosquitoes on large diameter arc surfaces such as pipelines. Figure 13-14 As shown. Under the initial condition, the convex shaft 32 on the second racket face shell connecting section 31 is inserted into the groove 22 (numbered d) on the first racket face shell connecting section 21. When the electric grid needs to be bent, one hand grasps the handle 25 and the other hand grasps the racket bar 1, and the first racket face shell 2 is rotated 45° counterclockwise around the rotation axis 24. At this time, the elastic potential energy of the compression spring 33 is released, and the convex shaft 32 on the second racket face shell connecting section 31 is pushed into the groove 22 (numbered c), and the relative position between the first racket face shell 2 and the second racket face shell 3 is locked again.

[0060] Embodiment 3:

[0061] This scheme folds the electric net 135 degrees, which can be used to catch mosquitoes on small diameter arc surfaces such as ropes and clothes hangers. Figure 15-16 As shown. Under the initial condition, the convex shaft 32 on the second racket face shell connecting section 31 is inserted into the groove 22 (numbered d) on the first racket face shell connecting section 21. When the electric grid needs to be bent, one hand grasps the handle 25 and the other hand grasps the racket bar 1, and the first racket face shell 2 is rotated 135° counterclockwise around the rotation axis 24. At this time, the elastic potential energy of the compression spring 33 is released, and the convex shaft 32 on the second racket face shell connecting section 31 is pushed into the groove 22 (numbered a), and the relative position between the first racket face shell 2 and the second racket face shell 3 is locked again.

[0062] Embodiment 4:

[0063] This solution folds the electric grid 270° (90° in the opposite direction) and can be used to catch mosquitoes in corners and other places. Fig.17 As shown. Under the initial condition, the convex shaft 32 on the second racket face shell connecting section 31 is inserted into the groove 22 (numbered d) on the first racket face shell connecting section 21. When the electric grid needs to be bent, one hand grasps the handle 25 and the other hand grasps the racket bar 1, and the first racket face shell 2 is rotated 90° clockwise around the rotation axis 24. At this time, the elastic potential energy of the compression spring 33 is released, and the convex shaft 32 on the second racket face shell connecting section 31 is pushed into the groove 22 (numbered f), and the relative position between the first racket face shell 2 and the second racket face shell 3 is locked again.

[0064] Embodiment 5:

[0065] This solution folds the electric net by 90° and can be used to catch mosquitoes on the ceiling. The specific operation method is consistent with that of embodiment 1, that is, the first racket shell 2 is rotated 90° counterclockwise and the convex shaft 32 is pushed into the groove 22 numbered b. Fig.18The left side shows the effect of using the bendable electric mosquito swatter to catch mosquitoes on the ceiling. The user can stand on the ground and hold the swatter rod 1 vertically upwards, and use the electric net on the first swatter shell 2 to approach the ceiling, so as to catch mosquitoes on the ceiling. Fig.18 On the right is the effect of using a traditional electric mosquito swatter for comparison. When using it, the user needs to stick the entire electric mosquito swatter horizontally to the ceiling. At this time, the user cannot reach the ceiling when standing on the ground. Often, one or two chairs are needed to raise the feet to reach the ceiling, which is both dangerous and inconvenient.
