DETAILED DESCRIPTION

[0026] The specific implementation of the utility model is further described below through specific embodiments and in conjunction with the accompanying drawings.

[0027] Embodiment one:

[0028] Dry lithium general purpose flashlight, such as Figure 1As shown, the main body of the flashlight is divided into a head 1 and a barrel, and the barrel is further divided into a shell 2 and a base 3. The head 1 and the barrel are separated, and the shell 2 and the base 3 are separated. A switch button 18 is arranged on the side of the end of the head 1 close to the barrel, and a hole for passing the switch button 18 is arranged in the upper position of the barrel. When the head 1 is connected to the barrel, the lower half of the head 1 is completely contained in the barrel, and the switch button 18 on this part extends out from the corresponding hole. A locking button is also arranged on the upper part of the switch button 18. After the locking button extends out of the corresponding hole of the barrel, the barrel and the barrel are fixed by a mortise and tenon structure to avoid the separation of the barrel and the barrel when the switch button 18 is pressed. The barrel and the barrel are not connected by a knob structure, which is conducive to fully concentrating the circuit on the head 1, and also facilitates the installation of the barrel and the barrel.

[0029] The barrel is divided into two parts: a shell 2 and a base 3. The shell 2 and the base 3 are hollow inside. Both ends of the shell 2 are provided with openings, and only the top end of the base 3 is provided with an opening. The shell 2 is used to accommodate the battery holder. The outer surface of the bottom of the shell 2 is provided with an external thread, and the inner side of the top of the base 3 is provided with an internal thread. The shell 2 is connected to the base 3 by rotation, and a sealing ring is also provided at the connection between the base 3 and the shell 2 to enhance the sealing between the shell 2 and the base 3. The inner diameter of the position where the upper half of the base 3 is fixed to the shell 2 is larger than the inner diameter of the lower half. The outer side of the shell 2 is provided with many anti-slip grooves to prevent the user from slipping out of the hand when using it.

[0030] like Figure 2 and Figure 3 As shown, a battery holder is provided in the barrel body for accommodating batteries that provide power for the flashlight. The battery holder of the flashlight can be divided into two types: a dry battery holder 4 and a lithium battery holder 5. The dry battery holder 4 is used to accommodate dry batteries, and the lithium battery holder 5 is used to accommodate lithium batteries. Both battery holders are matched with the same type of flashlight. By changing the type of battery holder inside the flashlight, the type of internal battery can be replaced. Among them, the lithium battery holder 5 is divided into a main section 15 and a charging section 16. The main section 15 is located at the upper end, and the charging section 16 is located at the lower end. The diameter of the main section 15 is larger than the diameter of the charging section 16. A charging hole 17 is provided on the punching section, and an opening of the same specification is provided on the base 3 of the barrel body. When installing, the main section 15 of the lithium battery holder 5 is located in the housing 2, and the charging section 16 is located in the base 3. At the same time, the charging hole 17 on the charging section 16 is opposite to the opening on the base 3. The lithium battery can be charged through the charging hole 17, and the lithium battery holder 5 does not need to be disassembled during charging. When the lithium battery is installed and fixed, it can be judged whether the housing 2 is fixed to the base 3 by observing whether the charging hole 17 is aligned with the opening.

[0031] The length of the dry battery bracket 4 is equal to the length of the main section 15 of the lithium battery bracket 5, and the bracket is also equal to the main section 15 bracket of the lithium battery bracket 5. A bracket base 11 is provided at the bottom of the dry battery bracket 4, and the bracket base 11 is fixed to the dry battery bracket 4 by bolts. When the dry battery inside the dry battery bracket 4 needs to be replaced, the bracket base 11 needs to be removed and replaced from the bottom of the dry battery bracket 4. Three hollow grooves 12 are provided on the side of the dry battery bracket 4, which can not only dissipate the heat of the internal battery, but also save the overall consumables of the dry battery bracket 4 and reduce the production cost. Two relative limit blocks 13 are also provided at the edge of the hollow groove 12 of the dry battery bracket 4. The limit blocks 13 are provided at the position where two adjacent batteries are fitted, which plays a role in limiting the battery. At the same time, due to the provision of the hollow groove 12, the overall strength of the side wall of the dry battery bracket 4 may be reduced. Many reinforcing ribs 14 are also provided on the side wall of the dry battery bracket 4 to increase the strength of the side wall of the dry battery bracket 4.

[0032] like Figure 4 As described above, whether it is a lithium battery holder 5 or a dry battery holder 4, the positive and negative electrodes are arranged at the top of the battery holder. A positive electrode terminal 9 is arranged in the middle of the top of the battery holder, and a negative electrode terminal ring 10 is arranged at the edge of the positive electrode terminal 9. The positive electrode terminal 9 and the negative electrode terminal ring 10 are arranged concentrically, and the bottom of the battery holder and the line connect the battery with the negative electrode and the negative electrode terminal ring 10 at the top. At the same time, the arrangement of the positive electrode terminal 9 and the negative electrode terminal ring 10 of the dry battery holder 4 can be divided into two ways, one of which is that the positive electrode terminal 9 and the negative electrode terminal ring 10 are arranged at the top of the dry battery holder 4, and the positive electrode of the battery is connected to the inner contact of the positive electrode terminal 9. In another case, the middle of the top of the dry battery holder 4 is an opening, and the positive electrode of the battery extends out of the opening, and the positive electrode of the battery is the positive electrode terminal 9.

[0033] like Figure 5 As shown, a positive connection point 7 is arranged in the middle of one end portion where the barrel head 1 is connected to the barrel body, and three negative terminal posts 8 are arranged around it. The positive connection point 7 is used to connect with the positive terminal post 9 on the battery holder, and the negative terminal post 8 is connected with the negative terminal ring 10 on the battery holder, so as to supply power to the light bulb on the barrel head 1.

[0034] In this embodiment, two types of battery holders, a dry cell holder 4 and a lithium cell holder 5, are designed to enable the use of dry cells and lithium cells in the same flashlight, thereby enriching the power supply modes of the flashlight and meeting the different needs of customers.

[0035] Embodiment 2:

[0036] The main body of the flashlight in this embodiment is divided into a barrel head 1 and a barrel body, and the barrel body is further divided into a shell 2 and a base 3. The barrel head 1 and the barrel body are separated, and the shell 2 and the base 3 are separated. A switch button 18 is arranged on the side of the end of the barrel head 1 close to the barrel body, and a hole for passing the switch button 18 is arranged in the upper position of the barrel body. When the barrel head 1 is connected to the barrel body, the lower half of the barrel head 1 is completely contained in the barrel body, and the switch button 18 on this part extends out from the corresponding hole. A locking button is also arranged on the upper part of the switch button 18. After the locking button extends out from the corresponding hole of the barrel body, the barrel body and the barrel body will be fixed by a mortise and tenon structure, so as to avoid the separation of the barrel body and the barrel body when the switch button 18 is pressed. The barrel body and the barrel body are not connected by a knob structure, which is conducive to fully concentrating the circuit on the barrel head 1, and also facilitates the installation of the barrel body and the barrel body.

[0037] The barrel is divided into two parts: a shell 2 and a base 3. The shell 2 and the base 3 are hollow inside. Both ends of the shell 2 are provided with openings, and only the top end of the base 3 is provided with an opening. The shell 2 is used to accommodate the battery holder. The outer surface of the bottom of the shell 2 is provided with an external thread, and the inner side of the top of the base 3 is provided with an internal thread. The shell 2 is connected to the base 3 by rotation, and a sealing ring is also provided at the connection between the base 3 and the shell 2 to enhance the sealing between the shell 2 and the base 3. The inner diameter of the position where the upper half of the base 3 is fixed to the shell 2 is larger than the inner diameter of the lower half. The outer side of the shell 2 is provided with many anti-slip grooves to prevent the user from slipping out of the hand when using it.

[0038] like Figure 2 and Figure 3 As shown, a battery holder is provided in the barrel body for accommodating batteries that provide power for the flashlight. The battery holder of the flashlight can be divided into two types: a dry battery holder 4 and a lithium battery holder 5. The dry battery holder 4 is used to accommodate dry batteries, and the lithium battery holder 5 is used to accommodate lithium batteries. Both battery holders are matched with the same type of flashlight. By changing the type of battery holder inside the flashlight, the type of internal battery can be replaced. Among them, the lithium battery holder 5 is divided into a main section 15 and a charging section 16. The main section 15 is located at the upper end, and the charging section 16 is located at the lower end. The diameter of the main section 15 is larger than the diameter of the charging section 16. A charging hole 17 is provided on the punching section, and an opening of the same specification is provided on the base 3 of the barrel body. When installing, the main section 15 of the lithium battery holder 5 is located in the housing 2, and the charging section 16 is located in the base 3. At the same time, the charging hole 17 on the charging section 16 is opposite to the opening on the base 3. The lithium battery can be charged through the charging hole 17, and the lithium battery holder 5 does not need to be disassembled during charging. When the lithium battery is installed and fixed, it can be judged whether the housing 2 is fixed to the base 3 by observing whether the charging hole 17 is aligned with the opening.

[0039] The length of the dry battery bracket 4 is equal to the length of the main section 15 of the lithium battery bracket 5, and the bracket is also equal to the main section 15 bracket of the lithium battery bracket 5. A bracket base 11 is provided at the bottom of the dry battery bracket 4, and the bracket base 11 is fixed to the dry battery bracket 4 by bolts. When the dry battery inside the dry battery bracket 4 needs to be replaced, the bracket base 11 needs to be removed and replaced from the bottom of the dry battery bracket 4. Three hollow grooves 12 are provided on the side of the dry battery bracket 4, which can not only dissipate the heat of the internal battery, but also save the overall consumables of the dry battery bracket 4 and reduce the production cost. Two relative limit blocks 13 are also provided at the edge of the hollow groove 12 of the dry battery bracket 4. The limit blocks 13 are provided at the position where two adjacent batteries are fitted, which plays a role in limiting the battery. At the same time, due to the provision of the hollow groove 12, the overall strength of the side wall of the dry battery bracket 4 may be reduced. Many reinforcing ribs 14 are also provided on the side wall of the dry battery bracket 4 to increase the strength of the side wall of the dry battery bracket 4.

[0040] like Figure 4 As described above, whether it is a lithium battery holder 5 or a dry battery holder 4, the positive and negative electrodes are arranged at the top of the battery holder. A positive electrode terminal 9 is arranged in the middle of the top of the battery holder, and a negative electrode terminal ring 10 is arranged at the edge of the positive electrode terminal 9. The positive electrode terminal 9 and the negative electrode terminal ring 10 are arranged concentrically, and the bottom of the battery holder and the line connect the battery with the negative electrode and the negative electrode terminal ring 10 at the top. At the same time, the arrangement of the positive electrode terminal 9 and the negative electrode terminal ring 10 of the dry battery holder 4 can be divided into two ways, one of which is that the positive electrode terminal 9 and the negative electrode terminal ring 10 are arranged at the top of the dry battery holder 4, and the positive electrode of the battery is connected to the inner contact of the positive electrode terminal 9. In another case, the middle of the top of the dry battery holder 4 is an opening, and the positive electrode of the battery extends out of the opening, and the positive electrode of the battery is the positive electrode terminal 9.

[0041] like Figure 5 As shown, a positive connection point 7 is arranged in the middle of one end portion where the barrel head 1 is connected to the barrel body, and three negative terminal posts 8 are arranged around it. The positive connection point 7 is used to connect with the positive terminal post 9 on the battery holder, and the negative terminal post 8 is connected with the negative terminal ring 10 on the battery holder, so as to supply power to the light bulb on the barrel head 1.

[0042] A voltage regulating circuit 6 is provided in the flashlight head 1. The voltage regulating circuit 6 is divided into a boost circuit and a buck circuit, and is controlled by a control chip. When the discharge voltage of the dry battery in the flashlight is lower than the working voltage, the boost circuit can be called to boost the voltage to the working voltage. When the discharge voltage of the dry battery in the flashlight is higher than the working voltage, the buck circuit can be called to buck the voltage to the working voltage. For example, the lithium battery is 3.6V, and the dry battery pack is three 1.2V dry batteries. The boost-boost structure does not work. When four 1.2V dry batteries are used, the voltage exceeds the working voltage, and the buck structure works. When one 1.2V dry battery is used, the voltage is lower than the working voltage, and the boost structure works.

[0043] In this embodiment, a voltage regulating circuit 6 is designed inside the cartridge head 1 to enable the use of dry batteries with different voltages.

[0044] Embodiment three:

[0045] like Figure 6 , Figure 7 and Figure 8 As shown, the main body of the flashlight in this embodiment is divided into a barrel head 1 and a barrel body, and the barrel body is further divided into a shell 2 and a base 3. The barrel head 1 and the barrel body are separated, and the shell 2 and the base 3 are separated. A switch button 18 is arranged on the side of the end of the barrel head 1 close to the barrel body, and a hole for passing the switch button 18 is arranged in the upper position of the barrel body. When the barrel head 1 is connected to the barrel body, the lower half of the barrel head 1 is completely contained in the barrel body, and the switch button 18 on this part extends out from the corresponding hole. A locking button is also arranged on the upper part of the switch button 18. After the locking button extends out from the corresponding hole of the barrel body, the barrel body and the barrel body will be fixed by a mortise and tenon structure to avoid the separation of the barrel body and the barrel body when the switch button 18 is pressed. The barrel body and the barrel body are not connected by a knob structure, which is conducive to fully concentrating the circuit on the barrel head 1, and also facilitates the installation of the barrel body and the barrel body.

[0046] The barrel is divided into two parts: a shell 2 and a base 3. The shell 2 and the base 3 are hollow inside. Both ends of the shell 2 are provided with openings, and only the top end of the base 3 is provided with an opening. The shell 2 is used to accommodate the battery holder. The outer surface of the bottom of the shell 2 is provided with an external thread, and the inner side of the top of the base 3 is provided with an internal thread. The shell 2 is connected to the base 3 by rotation, and a sealing ring is also provided at the connection between the base 3 and the shell 2 to enhance the sealing between the shell 2 and the base 3. The inner diameter of the position where the upper half of the base 3 is fixed to the shell 2 is larger than the inner diameter of the lower half. The outer side of the shell 2 is provided with many anti-slip grooves to prevent the user from slipping out of the hand when using it.

[0047] A battery holder is provided inside the barrel to accommodate batteries that provide power to the flashlight. The battery holder of the flashlight can be divided into two types: a dry cell holder 4 and a lithium cell holder 5. The dry cell holder 4 is used to accommodate dry cells, and the lithium cell holder 5 is used to accommodate lithium cells. Both battery holders are compatible with the same flashlight. By replacing the type of battery holder inside the flashlight, the type of internal battery can be replaced. In this embodiment, the dry cell holder 4 can only accommodate one dry cell. Among them, the positive and negative poles of the battery holder are respectively distributed at the upper and lower ends, and the positive and negative poles on the flashlight are also respectively distributed at the barrel head 1 and the base 3. This reduces the circuit for replacing the electrodes inside the battery holder and reduces the difficulty of producing the battery holder.

[0048] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
