[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] As shown in the figure, the refillable nozzle includes a nozzle assembly, and a liquid filling seat 10 is detachably connected to the bottom of the nozzle assembly. The internal principle structure of the nozzle assembly belongs to the conventional setting of the prior art, that is, the liquid in the bottle body 13 is discharged outward by pressing. The liquid can be an emulsion or a non-emulsion liquid, and the liquid discharge form can be a spray or a non-spray. Among them, the nozzle assembly includes an outer shell 6, and an inner sleeve 5 is installed at the inner center position of the outer shell 6. The inner sleeve 5 is clamped in the middle position of the outer shell 6. The difference is that the outer shell 6 and the liquid filling seat 10 are detachably connected. In this example, the outer shell 6 and the liquid filling seat 10 are connected by a threaded connection. Other methods can also be used for detachable connection, which is not limited here. The bottom of the inner sleeve 5 has a first boss 501 protruding downward, and the bottom of the first boss 501 has a second boss 502 protruding downward.

[0024] More specifically, in this example, the spray head assembly further comprises a piston 16 mounted in the center of the inner sleeve 5, the piston 16 and the inner sleeve 5 are sealingly and slidingly matched, a valve needle 4 having an inverted T-shaped cross section is provided inside the piston 16, a spring 2 is provided between the lower surface of the valve needle 4 and the inner bottom of the inner sleeve 5, a nozzle 2 is provided above the piston 16, the nozzle 2 is sleeved on the outside of the valve needle 4, a spring 3 is provided on the outside of the nozzle 2, a button 1 is provided above the nozzle 2, the button 1 and the nozzle 2 are synchronously moved in the axial direction, and when the button 1 is pressed, the nozzle 2, the valve needle 4 and the piston 16 can be driven downward and the spring 2 7 is pressed. The compression is performed, so that the volume of the space formed between the piston 16 and the inner sleeve 5 decreases. When the button 1 is released, the nozzle 2, the valve needle 4, and the piston 16 move upward under the elastic force of the spring 2 7. The volume formed between the piston 16 and the inner sleeve 5 increases and the pressure decreases. As a result, the liquid in the bottle body 13 is introduced into the space between the piston 16 and the inner sleeve 5 through the liquid pipe 11. When the button 1 is continued to be pressed, the volume between the piston 16 and the inner sleeve 5 gradually decreases, and the liquid flows upward through the gap between the valve needle 4 and the piston 16, and is finally discharged outward from the internal channel of the button 1, completing the entire liquid discharge process.

[0025] The liquid filling seat 10 has a liquid channel 9 and an exhaust channel 15 that are arranged through-through. The liquid channel 9 is installed with a liquid pipe 11 extending downward, and the exhaust channel 15 is installed with an exhaust pipe 12 extending downward. The liquid channel 9 is connected to the internal channel of the nozzle assembly. A seal is provided between the nozzle assembly and the liquid filling seat 10. When the nozzle assembly is installed to the liquid filling seat 10, the nozzle assembly can seal the exhaust channel 15.

[0026] The sealing member includes a sealing ring 8 installed below the nozzle assembly. Specifically, the sealing ring 8 is mounted on the outer wall of the first boss 501. The downward projection of the sealing ring 8 can cover the exhaust channel 15. After the nozzle assembly is connected to the liquid filling seat 10, the sealing ring 8 is pressed to achieve the sealing of the exhaust channel 15, so that when the container bottle is used normally, the exhaust channel 15 is in a closed state, which can avoid the problem of leakage.

[0027] The sealing component also includes a sealing ring 2 14 installed above the liquid channel 9 of the liquid filling seat 10. After the nozzle assembly is connected to the liquid filling seat 10, the nozzle assembly can compress the sealing ring 2 14 so that the liquid channel 9 is connected to the internal channel of the nozzle assembly and the connection is in a sealed state. Specifically, the lower end surface of the second boss 502 protruding below the inner sleeve 5 can abut against the upper surface of the sealing ring 1 8 and press the sealing ring 1 8, so that when the liquid channel 9 of the liquid filling seat 10 is connected to the internal channel of the nozzle assembly, its connection part is in a sealed state, thereby avoiding leakage problems.

[0028] Specifically, the bottom of the liquid filling seat 10 is detachably connected to the bottle body 13. The connection method between the liquid filling seat 10 and the bottle body 13 can adopt a lock shell, combined tooth groove, jaw pressing, snap connection, threaded connection, etc., to ensure that when the liquid filling seat 10 is installed on the bottle body 13, it can be firmly connected and the connection part is in a sealed state to avoid leakage. The liquid pipe 11 and the exhaust pipe 12 both extend to the internal position of the bottle body 13.

[0029] Specifically, the exhaust pipe 12 extends into the bottle body 13 to a position near the bottle mouth, the middle of the bottle body 13 or the bottom of the bottle. This arrangement is to meet different filling methods. That is, when the exhaust pipe 12 extends to the bottom of the bottle, the bottle body 13 can be turned upside down and filled with liquid using other perfume bottles. When the end of the exhaust pipe 12 is near the bottle mouth or the bottle body 13, the bottle body 13 is upright and filled with liquid using a syringe.

[0030] In this example, the liquid channel 9 is located at the center of the liquid filling seat 10, mainly used to match the nozzle assembly with the channel located in the middle position. When the internal channel of the nozzle assembly is not in the center, the liquid channel 9 may also not be in the center of the liquid filling seat 10.

[0031] Working principle: When this refillable nozzle is in use, its upper end is connected to the nozzle assembly and its lower end is connected to the bottle body 13. When the button 1 of the nozzle assembly is pressed, the liquid in the bottle body 13 can flow upward along the liquid tube 11 and finally be discharged outward through the internal channel of the nozzle assembly. During this process, the exhaust channel 15 is in a closed state, which can avoid leakage problems. When liquid needs to be replenished, the nozzle assembly can be disassembled and other container bottles can be used to align with the channel opening of the liquid channel 9 for liquid replenishment, or a syringe can be used for liquid replenishment. During the liquid replenishment process, the air in the bottle body 13 can be discharged outward from the exhaust channel 15, avoiding the problem of excessive pressure in the bottle and inability to replenish liquid.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
