[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0030] Please see Figures 1 to 3 The present invention provides a power supply with an elastic control element and a conductive needle, comprising a battery body 1 and an elastic element 2.

[0031] The battery body 1 includes a shell 11, a first sealing plug 12, a second sealing plug 13, and a negative electrode conductive rod 14;

[0032] The outer shell 11 is open at both ends. The first sealing plug 12 is disposed at one open end of the outer shell 11, and the second sealing plug 13 is disposed inside the outer shell 11. The first sealing plug 12, the outer shell 11 and the second sealing plug 13 form a sealed inner cavity, and the outer shell 11 and the second sealing plug 13 form an outer cavity.

[0033] The negative electrode conductive rod 14 passes through the first sealing plug 12 and the second sealing plug 13. One end of the negative electrode conductive rod 14 protrudes from the first sealing plug 12, and the other end of the negative electrode conductive rod 14 protrudes from the second sealing plug 13. The end of the negative electrode conductive rod 14 near the second sealing plug 13 is located in the outer cavity.

[0034] The elastic element 2 is located inside the outer cavity, and the negative electrode conductive rod 14 protrudes from the top surface of the elastic element 2.

[0035] Specifically, in this embodiment, the outer shell 11 is an aluminum shell structure with openings at both ends. A first sealing plug 12 is inserted into one opening of the outer shell 11, and a second sealing plug 13 is inserted from the other end of the outer shell 11 and pushed into the outer shell. The first sealing plug 12, the second sealing plug 13 and the outer shell 1 form a sealed inner cavity. The side of the second sealing plug 13 away from the first sealing plug 12 is the outer cavity. Both the first sealing plug 12 and the second sealing plug 13 have through holes for the negative electrode conductive rod 14 to pass through. The end of the negative electrode conductive rod 14 near the first sealing plug 12 protrudes from the first sealing plug 12, and the end of the negative electrode conductive rod 14 near the second sealing plug 13 protrudes from the second sealing plug 13. The elastic element 2 is preferably made of silicone. The elastic element 2 has a through hole, and the through hole of the elastic element 2 is fitted onto the negative electrode conductive rod 14. The elastic element 2 is located in the outer cavity. The end of the elastic element 2 abuts against the second sealing plug 13, and the other end of the elastic element 2 is exposed in the outer cavity. The distance between the end face of the elastic element 2 and the opening end of the outer shell 11 is greater than the distance between the end face of the negative electrode conductive rod 14 and the opening end of the outer shell 11. The end of the negative electrode conductive rod 14 near the elastic element 2 is connected to an external electrical appliance and is in a power supply state. The end of the negative electrode conductive rod 14 near the first sealing plug 12 is connected to an external charging power source and is in a charging state, which meets the requirements of simultaneous power supply and charging, that is, the requirement of extending the power supply cycle. The setting of the elastic element 2 is based on the following principle: When power is needed, an external force is applied to the electrical appliance, and the electrical appliance is electrically connected to the negative electrode conductive rod 14. At the same time, the elastic element 2 is in a compressed state. Conversely, when the external force applied to the electrical appliance is removed, the elastic element 2 releases its elastic force and pushes the electrical appliance away, so that the electrical appliance is separated from the negative electrode conductive rod 14 and the power is off.

[0036] By setting a shell 11 with openings at both ends, a first sealing plug 12 is used to block one opening end of the shell 11, and a second sealing plug 13 extends into the shell 11. The spacing between the first sealing plug 12 and the second sealing plug 13 divides the shell 11 into a sealed inner cavity and an outer cavity structure. The negative electrode conductive rod 14 passes through the first sealing plug 12 and the second sealing plug 13, with both ends of the negative electrode conductive rod 14 protruding from the first sealing plug 12 and the second sealing plug 13, respectively. An elastic member 2 is located in the outer cavity and close to the second sealing plug 13, with the end face of the negative electrode conductive rod 14 protruding from the end face of the elastic member 2. This structure allows one end of the negative electrode conductive rod 14 to be connected to an external electrical appliance, and the other end to be connected to a charging power source, thus fulfilling the needs for power supply and charging, while also satisfying the function of controlling the electrical appliance by pressing.

[0037] The end of the first sealing plug 12 protrudes from the end of the outer shell 11. This structure divides the first sealing plug 12 into two parts, one part located inside the outer shell 11 and the other part located outside the outer shell 11. The first sealing plug 12 is made of elastic rubber material. The first sealing plug 12 located inside the outer shell 11 is compressed and tightly connected to the outer shell 11. The first sealing plug 12 located outside the outer shell 11 is in a free state. The radial dimension of this part is larger than the inner diameter of the outer shell 11, that is, it has the effect of a cap on the outer shell 11, further improving the sealing effect.

[0038] The outer shell 11 is provided with a groove 111, which is located at the intersection of the outer shell 11 and the first sealing plug 12, and at the intersection of the outer shell 11 and the second sealing plug 13. The groove 111 is arranged in a ring shape radially around the outer shell 11. Pressure is applied to the outer shell 1 and the first sealing plug 12 to form the groove 111, thereby improving the connection between the first sealing plug 12 and the outer shell 11. Preferably, two parallel grooves 111 are processed at the intersection of the outer shell 11 and the second sealing plug 13 to enhance the sealing performance of the second sealing plug 13 to the sealed inner cavity.

[0039] The battery body 1 also includes a negative electrode ring 15, a separator layer 16, and a positive electrode ring 17 arranged sequentially from the inside to the outside. The negative electrode ring 15, the separator layer 16, and the positive electrode ring 17 are all located in a sealed inner cavity. The negative electrode ring 15 is connected to the negative electrode conductive rod 14, and the positive electrode ring 17 is connected to the outer shell 11. The separator layer 16 isolates the negative electrode ring 15 and the positive electrode ring 17.

[0040] The battery body 1 also includes a conductive medium 18, which is located between the first sealing plug 12 and the positive electrode ring 17, and between the second sealing plug 13 and the positive electrode ring 17.

[0041] A negative electrode ring 15, a diaphragm layer 16, and a positive electrode ring 17 are installed inside the sealed cavity of the outer shell 11. The positive electrode ring 17 is attached to the inner surface of the outer shell 11. The negative electrode ring 15 is a hollow column that is sleeved on the negative electrode conductive rod 14. A diaphragm layer 16 is provided between the negative electrode ring 15 and the positive electrode ring 17. The middle part of the diaphragm layer 16 is wrapped with the negative electrode ring 15. Both ends of the diaphragm layer 16 in the length direction are connected to the negative electrode conductive rod 14 to isolate the negative electrode ring 15 and the positive electrode ring 17, thereby avoiding short circuits caused by the shedding of positive and negative electrode powder and improving service life. The sealed cavity of the outer shell 11 is filled with a conductive medium 18. Preferably, the conductive medium 18 is an electrolyte.

[0042] The negative electrode ring 15 is a hollow column and is sleeved on the negative electrode conductive rod 14 to increase the connection strength and improve the conductivity.

[0043] The positive electrode ring 17 is multiple, and the multiple positive electrode rings 17 are sequentially nested on the separator layer 16. This structure facilitates production and assembly and improves production efficiency.

[0044] The negative electrode conductive rod 14 is provided with an upper limit ring 141 and a lower limit ring 142, and the upper limit ring 141 and the lower limit ring 142 are spaced apart. The negative electrode ring body 15 is disposed between the upper limit ring 141 and the lower limit ring 142, further ensuring that the negative electrode ring body 15 and the negative electrode conductive rod 14 are in a relatively stable state after assembly.

[0045] The negative electrode conductive rod 14 is provided with a protrusion 143, which is located in the middle of the negative electrode conductive rod 14. The protrusion 143 is processed by knurling, which increases the friction between the negative electrode conductive rod 14 and the negative electrode ring 15, prevents the negative electrode ring 15 and the negative electrode conductive rod 14 from shifting, and improves the quality stability.

[0046] The power supply with elastic control element and conductive needle also includes light-emitting element 3. The light-emitting element 3 is disposed in the outer cavity and abuts against the elastic element 2. The light-emitting element 3 is provided with conductive sheet. The conductive sheet is disposed near the negative electrode conductive rod 14. Preferably, the light-emitting element 3 is an LED lamp. The conductive sheet of the LED lamp is electrically connected to one end of the negative electrode conductive rod 14 that protrudes from the outer shell 11. The battery supplies power to the light-emitting element 3. During use, it is charged through the other end of the negative electrode conductive rod 14, which satisfies the purpose of power supply and timely charging.

[0047] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
