Description

Technical Field

[0001] This utility model relates to the technical field of binary packaging, and in particular to a non-spraying quantitative binary bag pump. Background Technology

[0002] To facilitate use, many cosmetics, household products, and industrial products are used in aerosol form. Two-part packaging is a special packaging form for aerosol products.

[0003] Existing binary packaging, such as the PU valve, PU valve assembly and binary packaging gas cylinder disclosed in utility model patent CN216685709U, and the binary packaging valve and binary packaging structure disclosed in utility model patent CN218907881U, all involve adding a packaging bag connected to the spray valve inside the aerosol can. The object to be sprayed is placed inside the packaging bag, and compressed gas is placed between the aerosol can and the bag as a power source.

[0004] However, during the filling and use process, it was found that the existing binary packaging is inconvenient for filling materials and for dispensing materials in a metered manner, resulting in poor practicality. Therefore, there is an urgent need for a non-spraying metering binary bag pump to improve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a non-initiating quantitative binary bag pump that stores material in a storage mechanism through a valve body, and then seals and stores the material by cooperating with the storage mechanism through the valve body. During discharge, the storage mechanism is squeezed by the pressure application mechanism, and then the valve body is opened, and the material is quantitatively sprayed out through the discharge mechanism, thereby improving the practicality of the quantitative valve.

[0006] This utility model discloses a non-spraying quantitative binary bag pump, which includes a storage mechanism; it also includes a valve body, a discharge mechanism, and a pressure application mechanism. The valve body is installed on the pressure application mechanism, and the storage mechanism and the discharge mechanism are both installed on the valve body. The storage mechanism is located inside the pressure application mechanism, and the discharge mechanism is located outside the pressure application mechanism. The pressure applying mechanism squeezes the storage mechanism, the storage mechanism stores the material, the valve body conveys the material, and the discharge mechanism discharges the material. The material is stored in the storage mechanism through the valve body. The valve body and the storage mechanism work together to seal and store the material. When discharging, the pressure mechanism squeezes the storage mechanism, and then the valve body is opened. The material is then sprayed out in a metered manner through the discharge mechanism, thereby improving the practicality of the metering valve.

[0007] Preferably, the valve body includes a top cover, a housing, a valve body, a central rod, a piston, a spring, and a conduit. The housing is installed in the pressure applying mechanism, the top cover is installed on the top of the housing, the valve body is slidably installed on the top cover, and the bottom end of the valve body extends from the top of the top cover into the interior of the housing. The central rod is slidably installed in the valve body, and the bottom end of the central rod extends into the interior of the housing. A gap is provided between the central rod and the valve body. The piston is fitted onto the central rod, and the central rod can slide up and down. The bottom end of the spring is installed at the bottom of the housing, and the top end of the spring is installed at the bottom of the central rod. A central tube is provided in the middle of the bottom end of the housing, and a dosing chamber is provided between the housing, the central tube, and the piston. The top end of the conduit is inserted into the bottom of the housing, and the conduit communicates with the interior of the housing. During filling, the filling head of the filling equipment is aligned with the valve body, and the central rod is pressed downward by the pin inside the filling head. The central rod compresses the spring downward, creating a gap between the central rod and the piston, forming an entry channel for the material. The material first passes through the gap between the valve body and the central rod, and then through the gap between the central rod and the piston. The gap between the plugs is filled with material, which then fills the dosing chamber. Air and excess material in the dosing chamber are then discharged through a conduit into the storage mechanism until it is full. During discharge, pressing the valve body causes it to move the central rod and piston downwards, compressing the spring. The valve body separates from the top cover and expands outwards. Simultaneously, the top of the piston contacts the bottom of the valve body, sealing the top of the housing. Further pressing of the valve body causes the piston to align with the central tube. Continued pressing presses the valve body, piston, and central tube, pressurizing the material in the dosing chamber. When the pressure in the dosing chamber exceeds the spring's elasticity, the piston separates from the valve body, forming a discharge channel. The material in the dosing chamber then passes through the discharge channel between the piston and valve body, and through the gap between the valve body and the central rod into the discharge mechanism. After stopping the pressure on the valve body, the spring's elasticity resets the valve body, central rod, and piston. A pressure mechanism then compresses the storage mechanism, causing the material in the storage mechanism to refill the dosing chamber, thus improving the practicality of the metering valve.

[0008] Preferably, the storage mechanism includes a bladder, which is installed at the bottom of the valve body, and the bottom end of the conduit extends into the interior of the bladder; the material is stored through the bladder, thereby facilitating the replenishment of material into the dosing chamber.

[0009] Preferably, the contact surface between the bottom of the housing and the piston, and the contact surface between the top of the piston and the bottom of the valve body, are both arc surfaces; thereby improving the sealing effect inside the housing.

[0010] Preferably, the discharge mechanism includes a pressing head and a nozzle. The pressing head is mounted on the valve body, and the nozzle is mounted on the pressing head. When the user presses the pressing head, the material is discharged into the nozzle through the gap between the valve body and the central rod, and then sprayed out through the nozzle, thus achieving the discharge effect.

[0011] Preferably, a sealing ring is provided between the top cover and the pressure applying mechanism to seal the gap between the top cover and the pressure applying mechanism, thereby improving the sealing effect on the pressure applying mechanism and the inside of the housing.

[0012] Preferably, the pressurizing mechanism includes a storage tank, a sealing cap, and a protective cap. The outer edge of the top of the storage tank is bent outwards. The sealing cap is installed on the top of the storage tank, and the storage tank contains compressed air. The protective cap is fastened to the top of the storage tank, and the inner diameter of the bottom of the protective cap is smaller than the outer diameter of the sealing cap. The storage tank and the sealing cap form a sealed tank body to store compressed air. The compressed air is used to pressurize the inside of the bag, which facilitates filling the bag with material or discharging the material from the bag. The protective cap is installed on the top of the storage tank to protect the lower pressure head and the nozzle, improving the convenience of transporting the material in the storage tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The filling head of the filling equipment is aligned with the valve body, and the pin inside the filling head presses the central rod downward. The central rod compresses the spring downward, creating a gap between the central rod and the piston, forming an inlet channel for the material. The material first passes through the gap between the valve body and the central rod, and then through the gap between the central rod and the piston. The material then fills the dosing chamber. The air and excess material in the dosing chamber are then discharged into the bag through the conduit, improving the convenience of material filling. 2. During the filling process, air in the dosage chamber is expelled into the bag so that material is discharged on the first press; 3. By applying pressure to the material in the dosing chamber, the material in the dosing chamber is discharged, and then the material in the dosing chamber is replenished through the bag, so as to facilitate the quantitative spraying of the material.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0016] Example 1 It includes a storage mechanism; it also includes a valve body, a discharge mechanism and a pressure application mechanism. The valve body is mounted on the pressure application mechanism, and the storage mechanism and the discharge mechanism are both mounted on the valve body. The storage mechanism is located inside the pressure application mechanism, and the discharge mechanism is located outside the pressure application mechanism. The pressure applying mechanism squeezes the storage mechanism, the storage mechanism stores the material, the valve body conveys the material, and the discharge mechanism discharges the material. The valve body includes a top cover 1, a housing 2, a valve body 3, a central rod 4, a piston 5, a spring 6, and a conduit 9. The housing 2 is installed in the pressure application mechanism, the top cover 1 is installed on the top of the housing 2, the valve body 3 is slidably installed on the top cover 1, and the bottom end of the valve body 3 extends from the top end of the top cover 1 into the interior of the housing 2. The central rod 4 is slidably installed in the valve body 3, and the bottom end of the central rod 4 extends into the interior of the housing 2. A gap is provided between the central rod 4 and the valve body 3. The piston 5 is fitted on the central rod 4, and the central rod 4 can slide up and down. The bottom end of the spring 6 is installed at the bottom of the housing 2, and the top end of the spring 6 is installed at the bottom of the central rod 4. A central tube 7 is provided in the middle of the bottom end of the housing 2, and a dosing chamber 8 is provided between the housing 2, the central tube 7, and the piston 5. The top end of the conduit 9 is inserted into the bottom of the housing 2, and the conduit 9 communicates with the interior of the housing 2. The storage mechanism includes a bladder 10, which is installed at the bottom of the valve body, and the bottom end of the conduit 9 extends into the interior of the bladder 10. The contact surface between the bottom of the housing 2 and the piston 5 and the contact surface between the top of the piston 5 and the bottom of the valve body 3 are both arc surfaces; The discharge mechanism includes a lower pressure head 11 and a nozzle 12. The lower pressure head 11 is mounted on the valve body 3, and the nozzle 12 is mounted on the lower pressure head 11. A sealing ring 16 is provided between the top cover 1 and the pressure applying mechanism to seal the gap between the top cover 1 and the pressure applying mechanism. During filling, the filling head of the filling equipment is aligned with the valve body 3, and the pin inside the filling head presses the central rod 4 downwards. The central rod 4 compresses the spring 6 downwards, creating a gap between the central rod 4 and the piston 5, forming an inlet channel for the material. The material first passes through the gap between the valve body 3 and the central rod 4, and then through the gap between the central rod 4 and the piston 5, filling the dosing chamber 8. The air and excess material in the dosing chamber 8 are then discharged into the bag 10 through the conduit 9 until the bag 10 is full. During discharge, the user presses the pressure head 11, causing the valve body 3 to drive the central rod 4 and the piston 5 to compress the spring 6 downwards. After the valve body 3 separates from the top cover 1, it expands outwards, and at the same time, the top of the piston 5 contacts the bottom of the valve body 3, sealing the top of the housing 2. After sealing, the user presses down the pressure head 11 to align the piston 5 with the central tube 7. The user continues to press down the pressure head 11, causing the valve body 3, piston 5, and central tube 7 to pressurize the material in the dosing chamber 8. When the pressure in the dosing chamber 8 is higher than the elasticity of the spring 6, the piston 5 separates from the valve body 3, forming a discharge channel. The material in the dosing chamber 8 then passes through the discharge channel between the piston 5 and the valve body 3, and then through the gap between the valve body 3 and the central rod 4 to enter the nozzle 12. The material is then sprayed out through the nozzle 12. After stopping the pressing of the valve body 3, the elasticity of the spring 6 resets the valve body 3, the central rod 4, and the piston 5. The pressure mechanism also squeezes the bag 10, causing the material in the bag 10 to refill the dosing chamber 8, thereby improving the practicality of the metering valve.

[0017] Example 2 It includes a storage mechanism; it also includes a valve body, a discharge mechanism and a pressure application mechanism. The valve body is mounted on the pressure application mechanism, and the storage mechanism and the discharge mechanism are both mounted on the valve body. The storage mechanism is located inside the pressure application mechanism, and the discharge mechanism is located outside the pressure application mechanism. The pressure applying mechanism squeezes the storage mechanism, the storage mechanism stores the material, the valve body conveys the material, and the discharge mechanism discharges the material. The pressure-applying mechanism includes a storage tank 13, a sealing cap 14, and a protective cap 15. The outer edge of the top of the storage tank 13 is bent outward. The sealing cap 14 is installed on the top of the storage tank 13, and the storage tank 13 contains compressed air. The protective cap 15 is fastened to the top of the storage tank 13, and the inner diameter of the bottom of the protective cap 15 is smaller than the outer diameter of the sealing cap 14. Compressed air is stored in a sealed tank consisting of a storage tank 13 and a sealing cap 14. The material is stored in the material tube device through a valve body. The material is then sealed and stored by the cooperation of the valve body and the storage mechanism. When discharging, compressed air is used to pressurize the inside of the bag 10, and then the valve body is opened. The material is then quantitatively sprayed out through the discharge mechanism, thereby improving the practicality of the metering valve.

[0018] like Figures 1 to 6As shown, this utility model discloses a non-spraying quantitative binary bag pump. During operation, compressed air is first stored in a sealed tank consisting of a storage tank 13 and a sealing cap 14. During filling, the filling head of the filling equipment is aligned with the valve body 3, and the pin inside the filling head presses down on the central rod 4. The central rod 4 compresses the spring 6 downwards, creating a gap between the central rod 4 and the piston 5, forming a material entry channel. The material first passes through the gap between the valve body 3 and the central rod 4, then through the gap between the central rod 4 and the piston 5, filling the dosing chamber 8. The air and excess material in the dosing chamber 8 are then discharged into the bag 10 through the conduit 9 until the bag 10 is full. During discharge, the user presses down on the pressure head 11, causing the valve body 3 to drive the central rod 4 and piston 5 downwards, compressing the spring 6. The valve body 3 and the top cap 14 are then separated. After separation, the piston expands outward, and the top of the piston 5 contacts the bottom of the valve body 3 to seal the top of the housing 2. Then, the user presses down the pressure head 11 to connect the piston 5 with the central tube 7. The user continues to press down the pressure head 11 to pressurize the material in the dosage chamber 8 through the valve body 3, piston 5, and central tube 7. When the pressure in the dosage chamber 8 is higher than the elasticity of the spring 6, the piston 5 separates from the valve body 3 to form a discharge channel. The material in the dosage chamber 8 then passes through the discharge channel between the piston 5 and the valve body 3, and then through the gap between the valve body 3 and the central rod 4 to enter the nozzle 12. The material is sprayed out through the nozzle 12. After stopping the pressing of the valve body 3, the elasticity of the spring 6 resets the valve body 3, central rod 4, and piston 5. Compressed air is then used to pressurize the inside of the bag 10 to fill the dosage chamber 8 with the material in the bag 10.
