Description

Technical Field

[0001] This invention belongs to the field of liquid storage tank technology, and specifically relates to a two-component liquid storage tank that facilitates complete discharge. Background Technology

[0002] A dual-component storage tank is a packaging container that can independently store two different materials. It typically consists of an outer bottle and an inner cover. The outer bottle and the inner cover form an outer storage chamber, and the inner cover forms an inner storage chamber. The two materials are filled into the two chambers respectively, and mixing is achieved through a press-type discharge mechanism at the bottom. This effectively prevents the two materials from mixing prematurely and causing a chemical reaction, thus ensuring the storage stability of the materials.

[0003] Existing binary storage tanks have an upward-extending partition structure that divides the interior into two independent cavities. The suction pipe for dispensing is typically located in the upper cavity. When the two materials are mixed, the mixture is distributed between the upper and lower cavities. However, since the suction pipe can only draw material from the upper cavity, the material remaining in the bottom cavity cannot be directly discharged. Users must repeatedly invert the tank to gradually remove the material from the bottom cavity, making the process cumbersome and inconvenient. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a two-component liquid storage tank that facilitates complete discharge. This storage tank addresses the problem that in existing two-component liquid storage tanks, the mixed materials are distributed in two cavities, and since the suction tube can only extract the material in the upper cavity, the remaining material in the bottom cavity cannot be directly discharged. Users need to repeatedly invert the tank to gradually discharge the material in the bottom cavity, which is cumbersome and inconvenient.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this invention provides a two-component liquid storage tank that facilitates complete discharge. The tank includes a tank body and a nozzle mounted on the tank body for spraying the mixed liquid. The tank body has an upper cavity and a lower cavity formed by a partition. The partition extends into the upper cavity and forms a receiving cavity. An opening at the bottom of the partition connects the upper and lower cavities. Multiple first discharge ports are provided on the outer surface of the receiving cavity. A storage tank for storing additives is slidably sealed within the receiving cavity. Multiple second discharge ports are provided on the outer surface of the storage tank. A female valve is installed at the end of the tank body away from the nozzle, connecting the first and second discharge ports. A cover is provided at the bottom of the tank body, with the pressing end of the female valve exposed on the cover. A suction tube is fixedly connected to the suction end of the nozzle, passing through the opening and extending to the bottom of the tank body.

[0008] Preferably, the partition and the receiving cavity are integrally formed from the same metal material, and the bottom end of the partition is provided with a first rolled edge.

[0009] Furthermore, the storage hopper includes a hopper body and a threaded sealing cap at one end of the hopper body, with a sealing gasket installed between the hopper body and the sealing cap.

[0010] Furthermore, the inner bottom wall of the sealing cap has a conical surface that slopes towards the second discharge port.

[0011] Furthermore, two annular grooves are formed at the bottom of the outer surface of the barrel, and a sealing ring is installed between the annular grooves and the inner wall of the receiving cavity. The second discharge port is located between the two annular grooves.

[0012] Furthermore, the cavity has a cylindrical structure with an open top.

[0013] Furthermore, the tank body includes a tank body, a top cover, and a bottom cover. The tank body is cylindrical, and the top cover and bottom cover are respectively placed on the top and bottom of the tank body. The partition is located inside the tank body.

[0014] Furthermore, an installation opening is provided in the middle of the bottom cover, and the upper surface of the bottom cover is raised upwards.

[0015] Furthermore, the female valve includes a valve sealing cup, a fixed tube, a push rod, and a spring. The valve sealing cup is sealed in the middle of the bottom cover. The fixed tube is located inside the tank and is vertically and fixedly sealed in the insertion port of the valve sealing cup. The top of the push rod is located on the lower side of the storage tank. The bottom of the push rod is inserted into the fixed tube and elastically connected to the fixed tube through the spring. A pressing block is fixedly connected to the bottom of the push rod.

[0016] Furthermore, a through hole is provided in the center of the cover, and the pressing block is located inside the through hole.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention moves the storage hopper of the tank to the receiving cavity above the separator, and opens an opening in the separator to connect the upper cavity with the lower cavity. At the same time, the suction tube of the nozzle passes through the opening and extends to the bottom of the tank. The mixed material can be completely extracted by the suction tube under the suction action of the nozzle, without the need to repeatedly invert the tank, thereby avoiding material residue at the bottom and greatly improving the actual utilization rate of the material.

[0019] 2. By isolating the materials in the tank and the storage container, this invention can effectively prevent the two materials from coming into contact with each other in advance and causing a chemical reaction, thus ensuring the stability of the materials during storage. When in use, pressing the female valve at the bottom will cause a mixed liquid to form in the tank, making the two-component storage tank simple to operate and convenient to use.

[0020] 3. Furthermore, the separator and the receiving cavity are integrally molded from the same metal material, resulting in high structural strength and stability. This effectively avoids sealing failures or deformations caused by component splicing, extending the overall service life of the storage tank. The storage hopper achieves a sliding seal with the receiving cavity through a sealing ring within the annular groove. Combined with the design of the second discharge port located between the two sealing rings, this ensures both the sealing of the additives during storage and allows the additives to flow evenly into the upper cavity through the first and second discharge ports to mix with the main material when the female valve is pressed to move the storage hopper upwards, resulting in a more uniform mixing effect. The conical surface design of the inner bottom wall of the sealing cap guides the remaining additives in the storage hopper to converge towards the second discharge port, further reducing additive residue. The spring-loaded elastic connection structure of the female valve allows the push rod to automatically reset after pressing, ensuring the storage hopper returns to its initial sealed position. This design is convenient to operate and offers high reliability for repeated use. The tank adopts a split structure for the tank body, top cover, and bottom cover, which facilitates the assembly and subsequent maintenance of each component, reducing production and maintenance costs. The mounting port in the middle of the bottom cover and the raised design on the upper surface provide a stable mounting base for the female valve and also help the mixture in the lower cavity to converge towards the center of the tank bottom. Together with the suction pipe extending to the bottom, this further improves the thoroughness of discharge. These design details work together to give this two-component liquid storage tank significant advantages in practicality, reliability, and economy. Attached Figure Description

[0029] This specific embodiment is a two-component storage tank that facilitates complete discharge, and its structural schematic diagram is shown below. Figures 1-7 As shown, the storage tank includes a tank body 1 and a nozzle 2 mounted on the tank body 1 for spraying out the mixed liquid. The interior of the tank body 1 is divided into an upper cavity 4 and a lower cavity 5 by a partition 3. The partition 3 extends into the upper cavity 4 and forms a receiving cavity 6. An opening 7 is provided at the bottom end of the partition 3 to connect the upper cavity 4 and the lower cavity 5. Multiple first discharge ports 8 are provided on the outer surface of the receiving cavity 6. A storage tank 9 for storing additives is slidably sealed inside the receiving cavity 6. Multiple second discharge ports 10 are provided on the outer surface of the storage tank 9. A female valve 11 is installed at the end of the tank body 1 away from the nozzle 2. The female valve 11 is used to connect the first discharge ports 8 and the second discharge ports 10. A cover 12 is provided at the bottom of the tank body 1. The pressing end of the female valve 11 is exposed on the cover 12. A suction tube 13 is fixedly connected to the suction end of the nozzle 2. The suction tube 13 passes through the opening 7 and extends to the bottom of the tank body 1.

[0030] like Figure 1 and Figure 4 As shown: In this embodiment, the partition 3 and the receiving cavity 6 are integrally formed from the same metal material. The bottom end of the partition 3 is provided with a first rolled edge 301, which is sealed and fixed to the tank body 1.

[0031] like Figure 3 and Figure 6 As shown: In this embodiment, the storage tank 9 includes a tank body 901 and a sealing cap 902 threadedly sealed to one end of the tank body 901. A sealing gasket 903 is installed between the tank body 901 and the sealing cap 902. The sealing cap 902 is slightly smaller than the diameter of the tank body 901. After the curing agent is filled into the tank body 901, the sealing cap 902 is tightened and can be slidably inserted into the receiving cavity 6. The inner bottom wall of the sealing cap 902 has a conical surface 904 that is inclined towards the second discharge port 10. In this way, the curing agent in the storage tank 9 can be quickly discharged from the second discharge port 10 along the conical surface 904 during mixing, avoiding accumulation.

[0032] like Figure 3 and Figure 6 As shown: In this embodiment, two annular grooves 905 are formed at the bottom of the outer surface of the barrel 901. A sealing ring 906 is installed between the annular grooves 905 and the inner wall of the receiving cavity 6. The second discharge port 10 is located between the two annular grooves 905. The receiving cavity 6 has a cylindrical structure and the top of the receiving cavity 6 is open. The barrel 901 can slide along the receiving cavity 6 through the sealing ring 906. In the initial state, the first discharge port 8 and the second discharge port 10 are misaligned and isolated by the sealing ring 906 to prevent mixing.

[0033] like Figure 1 and Figure 2 As shown: In this embodiment, the tank 1 includes a tank body 101, a top cover 102 and a bottom cover 103. The tank body 101 is cylindrical. The top cover 102 and the bottom cover 103 are respectively placed on the top and bottom of the tank body 101. The partition 3 is located inside the tank body 101.

[0034] like Figure 3 and Figure 7 As shown: In this embodiment, the bottom cover 103 has an installation port in the middle, and the upper surface of the bottom cover 103 is raised upward. The female valve 11 includes a valve sealing cup 1101, a fixing tube 1102, a push rod 1103 and a spring 1104. The valve sealing cup 1101 is sealed and fitted in the middle of the bottom cover 103. The fixing tube 1102 is located inside the tank body 1 and is vertically fixed and sealed in the insertion port of the valve sealing cup 1101. The top end of the push rod 1103 is located on the lower side of the storage tank 9. The bottom end of the push rod 1103 is inserted into the fixing tube 1102 and is elastically connected to the fixing tube 1102 through the spring 1104. The bottom end of the push rod 1103 is fixedly connected to a pressing block 1105. The center of the cover body 12 has a through hole 1201, and the pressing block 1105 is located in the through hole 1201.

[0035] Working principle: 1. Initial state: The tank 1 is filled with raw materials and the storage tank 9 is filled with curing agent. At this time, the first discharge port 8 and the second discharge port 10 are misaligned and isolated by the sealing ring 906 to prevent mixing. 2. Activation stage: Press the pressing block 1105. The pressing block 1105 moves upward along the radial direction of the fixed tube 1102 via the push rod 1103. At this time, the spring 1104 is compressed, and the top of the push rod 1103 moves the storage tank 9 upward in the receiving cavity 6. At this time, the first discharge port 8 and the second discharge port 10 are connected, releasing the curing agent in the storage tank 9 and mixing it with the raw material in the tank 1. Since the bottom end of the separator 3 has an opening 7, the upper cavity 4 and the lower cavity 5 are connected, so that a mixed liquid is formed in the tank 1. 3. Spraying stage: The mixed liquid is sprayed out through the nozzle of the nozzle 2 to form a liquid film. Since the suction tube 13 at the suction end of the nozzle 2 passes through the opening 7 and extends to the bottom of the tank 1, the mixed liquid can be completely sprayed out.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
