[0024] The utility model provides a negative pressure filling device for a double-needle bottle, which belongs to a form of special-shaped glass ampoules, and has a cylindrical hollow barrel, and both axial ends thereof are gradually converged conical structures. Before the double-needle bottle is empty and not filled, the end of the conical body at one end is closed, and the end of the conical body at the other end has an opening, and the conical body and the opening form a bottle mouth 5 of the double-needle bottle, which is used to fill liquid into the double-needle bottle. After the filling is completed, the opening is melted and sealed, thereby forming a sealed double-needle ampoule bottle loaded with liquid medicine or oral liquid. The double-needle bottle is mainly a medical product, and easy-to-break stress rings or notches are formed on the conical bodies at both ends, and the user can break off the conical body at any end to obtain the internal liquid.

[0025] Reference Figure 1 The negative pressure filling device includes a platform 1 as a base, a loading tray 2 is arranged on the platform 1, and the loading tray 2 is driven by a motor arranged on the platform 1 to rotate. A plurality of clamps 21 for fixing the double-needle bottle are arranged on the circumference of the loading tray 2. The double-needle bottle cooperates with the clamp 21 through the cone body or the barrel body of the closed side thereof, and the double-needle bottle is axially fixed vertically, and the bottle mouth 5 of the double-needle bottle faces upward. In this embodiment, the clamp 21 is specifically a hollow sleeve-shaped structure, and the double-needle bottle can be inserted downward into the sleeve to be fixed.

[0026] A filler 3 is provided on the platform 1, and the filler 3 is located on the outer peripheral side of the loading tray 2. The filler 3 is fixed to the platform 1 through a bracket 4, and a vertical slide rail is formed on the bracket 4. The filler 3 is connected to the slide rail in a sliding manner and can be lifted and lowered along the slide rail. The rotation of the loading tray 2 can drive any double-needle bottle thereon to move to the bottom of the filler 3, and the filler 3 can cooperate with the bottle mouth 5 of the double-needle bottle after descending through the slide rail.

[0027] Reference Figure 2 A filling channel is provided inside the filler 3. The filling channel is columnar and arranged vertically. Three openings connected to the outside of the filler 3 are provided on the filling channel, namely a first opening 31 located at the bottom of the filler 3, a second opening 32 located at the top of the filler 3, and a third opening 33 located on the side of the filler 3. The second opening 32 is provided with a first solenoid valve 321, and the other end of the first solenoid valve 321 is connected to a liquid medicine barrel through a conduit. The liquid medicine barrel stores liquid medicine for filling; the third opening 33 is provided with a second solenoid valve 331, and the other end of the second solenoid valve 331 is connected to a vacuum pump through a conduit.

[0028] The first opening 31 is used to cooperate with the bottle mouth 5 of the double-needle bottle, referring to Figure 3 When the open cone of the double-needle bottle enters the filling channel through the first opening 31, the bottle mouth 5 is connected with the second opening 32 and the third opening 33, and the filling process can be carried out. The filling process includes first controlling the second solenoid valve 331 to open, starting the vacuum pump to evacuate the inside of the double-needle bottle, closing the second solenoid valve 331, and opening the first solenoid valve 321. At this time, the vacuum state in the double-needle bottle forms a suction effect, and the liquid medicine in the liquid medicine barrel is sucked into the double-needle bottle until the vacuum state is released, closing the first solenoid valve 321, and lifting the filler 3 to separate from the double-needle bottle to complete the filling.

[0029] In one embodiment, the inner wall of the first opening 31 is formed into a conical structure with the same peripheral shape as the bottle mouth 5, so that after the bottle mouth 5 enters the first opening 31, the inner peripheral wall of the first opening 31 is fully fitted with the outer peripheral wall of the bottle mouth 5, forming a sufficient seal in the circumferential direction to avoid air leakage and liquid leakage. Furthermore, the inner peripheral wall of the first opening 31 is made of a material with a certain elasticity, including but not limited to rubber, resin, etc., so that the bottle mouth 5 and the first opening 31 form an interference fit to improve the sealing effect.

[0030] In another embodiment, an annular rubber ring 34 is embedded on the inner circumferential wall of the first opening 31. After the bottle mouth 5 of the double-needle bottle is fully matched with the first opening 31, the inner circumference of the annular rubber ring 34 is fitted around the outer circumferential wall of the bottle mouth 5 in an interference fit to form a circumferential sealing effect, and the annular rubber ring 34 is arranged at a position close to the top opening of the bottle mouth 5 to avoid excessive liquid medicine remaining on the side of the bottle mouth 5.

[0031] The platform 1 is also provided with a cleaning device for cleaning the bottle mouth 5 and a sealing device for sealing the bottle mouth 5. The cleaning device and the sealing device are both arranged on the peripheral side of the loading tray 2. The rotation of the loading tray 2 can drive the double-needle bottle to move to the cleaning device station or the sealing device station. The cleaning device can preferably be an air-blowing cleaning device, including an air nozzle and an air storage device. The air nozzle sprays air toward the bottle mouth 5 of the double-needle bottle to blow away the liquid outside the bottle mouth 5, thereby achieving a cleaning effect; the sealing device is a melting sealing method, which uses a hydrogen and oxygen mixture to ignite a flame to heat the bottle mouth 5, melt the bottle mouth 5 to close its opening, and achieve the effect of sealing the double-needle bottle; the cleaning device and the sealing device both directly adopt devices that have been widely used in the prior art, such as devices used in the production and filling operations of other glass bottles and other types of ampoules, so they are not described in detail here.

[0032] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
