[0033] The present invention discloses a light-emitting structure 100 of an electric tester (hereinafter referred to as the light-emitting structure 100 for convenience of description), referring to Figure 1-Figure 2 As shown, the light-emitting structure 100 includes a support base 110, a display cover 120, a battery compartment 140, a battery 150, an LED lamp 160 and a neon lamp 170. The support base 110 defines an installation cavity with openings at both ends of the installation cavity. The display cover 120 is detachably mounted on one side of the support base 110. A circuit board 130 is provided in the installation cavity. The battery compartment 140 is rotatably mounted on the support base 110. The battery compartment 140 has an avoidance groove 141 that is arranged through it. The battery 150 is installed in the battery compartment 140. The LED lamp 160 and the neon lamp 170 are arranged vertically. The LED lamp 160 is electrically connected to the circuit board 130. The neon lamp 170 and the LED lamp 160 are arranged corresponding to the avoidance groove 141. It can be understood that the neon lamp 170 and the LED lamp 160 are arranged vertically and the LED lamp 160 is located in the avoidance groove 141 of the battery compartment 140, which does not affect normal operation. When the battery 150 is out of power, the neon lamp 170 works and the light is transmitted normally without being blocked. The neon lamp 170 and the LED lamp 160 are arranged vertically, which improves the compactness of the structure and improves the space utilization of the entire light-emitting structure 100.

[0034] The battery 150 is mainly used to power the circuit board 130 and the LED light 160, and is used to realize functions such as induction detection and on-off detection. These functions are the same as those of a general electric pen and will not be described in detail here. At the same time, since the battery compartment 140 is rotatably mounted on the support base 110, and the LED light 160 and the neon light 170 are arranged corresponding to the avoidance groove 141, when the battery 150 needs to be replaced, it is only necessary to remove the display cover 120 from the support base 110 and then rotate the drive battery compartment 140. During the rotation process, there will be no interference with the neon light 170 or the LED light 160. When the battery compartment 140 is rotated to the position where the battery 150 leaves the installation cavity ( Figure 5 The battery 150 can be replaced by simply moving the battery 150 to the position shown in the figure, which makes it convenient to replace the battery 150.

[0035] refer to Figure 2 As shown, the display cover 120 includes a transparent cover 121 and a metal ring 122. The circuit board 130 is provided with a contact piece 132 for abutting against the metal ring 122. It is understood that the metal ring 122 is sandwiched between the transparent cover 121 and the support base 110. The metal ring 122 and the metal contact piece 132 can connect the metal ring 122 to the circuit board 130, facilitating grounding. The transparent cover 121 can stably transmit light for user viewing.

[0036] refer to Figure 2 As shown, the support base 110 includes a first base 111 and a second base 112. The first base 111 is provided with a splicing protrusion 1111, and the second base 112 is provided with a splicing groove 1121. The splicing protrusion 1111 can be inserted into the splicing groove 1121 to splice the first base 111 and the second base 112. It can be understood that when the support base 110 is split into the first base 111 and the second base 112, the circuit board 130 is limited by the first base 111 and the second base 112, which can facilitate the installation of the circuit board 130 on the support base 110. During the maintenance process, it is also convenient to disassemble the entire light-emitting structure 100 and facilitate the maintenance of the circuit board 130. At the same time, the first base 111 and the second base 112 are connected by the splicing protrusion 1111 and the splicing groove 1121, which facilitates the assembly and disassembly of the first base 111 and the second base 112. In an alternative embodiment, the second base 112 is provided with a splicing protrusion 1111, and the first base 111 is provided with a splicing groove 1121. Of course, in other embodiments of the present invention, the first base 111 and the second base 112 can also be installed by connecting members such as screws and pins.

[0037] refer to Figure 2 and Figure 5As shown, the circuit board 130 is provided with at least one pair of electrode sheets 131. Each pair of electrode sheets 131 is used to accommodate a battery 150. The battery 150 accommodated between each pair of electrode sheets 131 is electrically connected to the corresponding electrode sheet 131. It is understood that because the battery compartment 140 is rotatably mounted on the support base 110, the electrical connection between the battery 150 and the circuit board 130 is achieved through the paired electrode sheets 131. In this way, when the battery compartment 140 drives the battery 150 to rotate into the installation cavity, the battery 150 can be stably inserted between the paired electrode sheets 131, ensuring a stable connection between the circuit board 130 and the battery 150. Optionally, the electrode sheets 131 are springs, and the spacing between the two springs is slightly less than the thickness of the battery 150. As a result, when the battery 150 is inserted between the paired electrode sheets 131, the positive and negative electrodes of the battery 150 can be stably stopped on the electrode sheets 131, ensuring a stable connection between the circuit board 130 and the battery 150. Of course, in other embodiments of the present invention, different structures may be selected to connect the battery 150 to the circuit board 130 according to the type of the battery 150 .

[0038] Optionally, in this embodiment, two batteries 150 are provided in the battery compartment 140, the two batteries 150 are located on both sides of the avoidance groove 141, and there are two pairs of electrode sheets 131. Of course, in other embodiments of the present invention, the number of batteries 150 can also be adjusted according to actual needs.

[0039] refer to Figure 3-Figure 5 As shown, the battery compartment 140 has a closed state ( Figure 3 and Figure 4 The position shown) and the open state perpendicular to the end surface of the support seat 110 ( Figure 5 The outer wall of the battery compartment 140 has a support protrusion 142. In the closed state, the support protrusion 142 abuts against the inner wall of the display cover 120. It can be understood that when the battery compartment 140 is in the closed state, each battery 150 is inserted between the paired electrode sheets 131 to achieve electrical connection between the battery 150 and the circuit board 130. At this time, the support protrusion 142 abuts against the inner wall of the display cover 120. Specifically, the support protrusion 142 abuts against the inner wall of the transparent cover 121, which can limit the loosening of the battery compartment 140 and ensure that the battery compartment 140 is stably fixed to the support base 110 in the closed state. When the battery compartment 140 is in the open state, the battery compartment 140 is perpendicular to the end surface of the support base 110. At this time, the battery 150 is separated from the paired electrode sheets 131 and is located outside the installation cavity, making it very convenient for users to replace the battery 150.

[0040] refer to Figure 4As shown, the support base 110 is provided with a rotation groove 101, and the battery compartment 140 is provided with an integrally formed rotation shaft 143. The rotation shaft 143 is engaged with the rotation groove 101 and can rotate relative to the rotation groove 101. It is understandable that during the installation process, after the first base 111 and the second base 112 are spliced to form the support base 110 and the circuit board 130 is installed on the support base 110, the battery 150 can be directly installed on the battery compartment 140, and then the rotation shaft 143 of the battery compartment 140 is engaged with the rotation groove 101. Then, the battery compartment 140 is rotated so that the battery 150 moves between the paired electrode sheets 131. At this time, the battery compartment 140 enters a closed state, and the battery 150 is electrically connected to the LED light 160 through the circuit board 130. By providing the rotation groove 101 on the support base 110 and engaging the rotation shaft 143 of the battery compartment 140 in the rotation groove 101, the installation and removal of the battery compartment 140 are facilitated. Of course, in other embodiments of the present invention, the battery compartment 140 may also be provided with a shaft hole, a rotating shaft is provided inside the shaft hole, and two shaft holes are provided at intervals on the support seat 110, the rotating shaft passes through the shaft hole and both ends are inserted into the shaft holes.

[0041] refer to Figure 3 As shown, a neon lamp 170 is positioned above the LED lamp 160. A support groove 102 is provided on the support base 110 to support the neon lamp 170. A receiving groove 103 is provided in the middle of the support groove 102, extending toward the circuit board 130. The LED lamp 160 is mounted within the receiving groove 103. It is understood that the brightness of the LED lamp 160 is greater than that of the neon lamp 170. The location of the neon lamp 170 above the LED lamp 160 ensures that the light-emitting structure 100 can consistently emit bright light during operation, and can also use different light colors for easy identification. Providing the support groove 102 on the support base 110 to support the neon lamp 170 ensures stable installation of the neon lamp 170. The receiving groove 103 is provided in the middle of the support groove 102, extending toward the circuit board 130. The LED lamp 160 is mounted within the receiving groove 103. This not only improves the compactness of the structure, but also ensures stable installation of the LED lamp 160 and alignment with the neon lamp 170, ensuring stable light transmission.

[0042] Optional, reference Figure 4 As shown, the support base 110 is further provided with wiring grooves 104 located on both sides of the support groove 102. The wires of the neon lamp 170 fit within the wiring grooves 104 and are connected to the circuit board 130. It is understood that fitting the wires of the neon lamp 170 within the wiring grooves 104 and being connected to the circuit board 130 can not only improve the aesthetics, but also protect the wires of the neon lamp 170 from damage.

[0043] Optional, reference Figure 2As shown, a wiring hole 105 is provided on the bottom wall of the receiving groove 103, and the wires of the LED lamp 160 pass through the wiring hole 105 and are connected to the circuit board 130. It can be understood that on the one hand, it can improve the aesthetics, and on the other hand, it can protect the wires of the LED lamp 160 from damage.

[0044] The present invention also discloses an electric test pencil, Figure 6-Figure 7 As shown, the voltage tester includes a body 200 and the aforementioned light-emitting structure 100. An open receiving cavity is provided at the end of the body 200, and the light-emitting structure 100 is mounted to the open end of the receiving cavity to seal it. Due to the aforementioned light-emitting structure 100, the voltage tester has a compact structure, high space utilization, and convenient battery 150 replacement. Furthermore, since the battery compartment 140 and battery 150 are concealed within the receiving cavity of the body 200, the device is aesthetically pleasing and improves user satisfaction.

[0045] Optionally, the light emitting structure 100 further includes an elastic member 180, which is a spring made of a conductive material. One end of the elastic member 180 is electrically connected to the circuit board 130, and the other end is electrically connected to the screwdriver bit in the pen body 200. The additional elastic member 180 can prevent the light emitting structure 100 from loosening from the screwdriver bit and causing poor contact.
