[0007] A connecting cylinder is fixedly connected inside the shoulder sleeve. The first end of the connecting cylinder is connected to the storage bottle, and the second end of the connecting cylinder is sealed to the liquid outlet end of the valve core through a sealing sleeve.

[0008] The pressure bottle is rotatably connected to the shoulder sleeve and is axially slidingly limited to each other. The cover is fixedly connected to a linkage sleeve. It also includes a linkage component, which is axially slidingly connected to the connecting cylinder and is axially rotating and limited to each other. The linkage component is threadedly connected to the linkage sleeve and is provided with a first pressing part. When the linkage component is threadedly adjusted toward the cover, the first pressing part abuts against the second pressing part, which can press the valve core.

[0009] The present invention is further configured such that the storage bottle has a vent hole, and a sealing element is provided at the vent hole. The sealing element is elastically pressed against the outside of the vent hole and can seal the vent hole.

[0010] The present invention is further configured such that the sealing element is annular and is fitted over the storage bottle; an annular groove is provided on the outside of the storage bottle, and the sealing element is embedded in the annular groove.

[0011] The present invention is further configured such that the first end of the connecting cylinder is located inside the storage bottle and is equipped with a material seat, and the outer periphery of the material seat is provided with several guide grooves, which connect the storage bottle and the liquid outlet end of the valve core; a spherical recess is formed on the upper side of the material seat.

[0012] The present invention is further configured such that the guide groove is inclined, and the upper end of the guide groove is inclined towards the outer periphery.

[0013] The present invention is further configured such that the liquid outlet end of the valve core extends into the second end of the connecting cylinder, and the liquid outlet end of the valve core can rotate axially and slide axially relative to the second end of the connecting cylinder.

[0014] The present invention is further configured such that the linkage component is sleeved outside the connecting cylinder, the outer periphery of the connecting cylinder is provided with a first guide slide part, the inner periphery of the linkage component is provided with a second guide slide part, the first guide slide part and the second guide slide part are slidably connected to each other; the outer periphery of the linkage component is provided with a third threaded part, the inner periphery of the linkage sleeve is provided with a fourth threaded part, the third threaded part and the fourth threaded part are threadedly connected to each other.

[0015] The present invention is further configured to include an outer cover, wherein the storage bottle has an outlet on the side facing away from the shoulder sleeve, the outer cover is installed on the outside of the storage bottle and can close the outlet; the outer cover is threadedly connected to the shoulder sleeve.

[0016] The present invention is further configured such that the connecting cylinder and the shoulder sleeve are fixedly connected by an annular partition portion, and an interface is formed at the end of the storage bottle facing the shoulder sleeve; a connecting sleeve portion is fixed to the partition portion, and the connecting sleeve portion and the interface are mutually sealed and fitted together.

[0017] The present invention is further configured such that the storage bottle is pre-vacuumed and the pressure bottle is pre-charged with high-pressure gas.

[0018] This utility model also provides a method of using the dual-chamber storage and dissolution device as described above.

[0020] In summary, this utility model has the following beneficial effects:

[0021] By using two bottles—a pressure bottle and a storage bottle—the solvent and the substance to be mixed can be stored separately in the two bottles, enabling separate storage and long-term preservation. High-pressure gas can quickly force the reagent into the storage bottle, allowing the substance to be mixed and the solvent to be dissolved rapidly, making it convenient for users.

[0022] The pressure bottle contains solvent and pressurized gas. When in use, rotating the pressure bottle causes relative rotation between the pressure bottle and the shoulder sleeve, which in turn drives the linkage to create a threaded connection. The linkage and the pressing valve move closer together, pressing down the valve core. The solvent in the pressure bottle is then ejected from the outlet of the valve core under the action of the pressurized gas. The solvent flows through the connecting tube into the storage bottle, where it mixes with the substance to be mixed, forming a mixed reagent.

[0023] The storage bottle contains lyophilized material. By shaping the lyophilized material into a spherical form and supporting it with a material seat having a spherical depression, the lyophilized material can rotate freely on the material seat. By opening a guide channel, which is inclined and distributed on the outer periphery of the material seat, the solvent and gas sprayed from the liquid outlet end of the valve core can be sprayed out from the guide channel, generating a jet on the spherical lyophilized material, driving the lyophilized material to rotate, and accelerating the dissolution of the lyophilized material.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] This embodiment discloses a dual-chamber storage and dissolution device, referring to... Figures 1-10 As shown, the package includes a shoulder sleeve 1, a pressure bottle 2, and a storage bottle 3. The shoulder sleeve 1 has a cylindrical structure and is located in the middle of the entire package. The storage bottle 3 and the pressure bottle 2 are respectively installed at both ends of the shoulder sleeve 1.

[0037] Reference Figure 2 , Figure 3 As shown, the pressure bottle 2 is equipped with a cap 9, and a press valve 10 is installed on the cap 9. The press valve 10 includes a valve core 101 that can be pressed to dispense liquid. The valve core 101 has a pressing part 102 and a dispensing end 1011. A connecting cylinder 12 is fixedly connected inside the shoulder sleeve 1. The first end 121 of the connecting cylinder 12 is connected to the storage bottle 3, and the second end 122 of the connecting cylinder 12 is sealed to the dispensing end 1011 of the valve core 101 through a sealing sleeve 7.

[0038] Pressure bottle 2 contains solvent and pressurized gas. Storage bottle 3 contains the substance to be mixed, which can be lyophilized material, powder, or other reagents. In this embodiment, lyophilized material is used as an example for detailed description.

[0039] When in use, by pressing the valve core 101, the solvent in the pressure bottle 2 can be sprayed out from the liquid outlet 1011 of the valve core 101 under the action of the pressurized gas; the solvent flows through the connecting tube 12 into the storage bottle 3, and the solvent and the lyophilized material 6 are mixed together, and the lyophilized material 6 is mixed and dissolved into the solvent to form a mixed reagent.

[0040] Reference Figure 3 , Figure 5 , Figure 6 As shown, the pressure bottle 2 and the shoulder sleeve 1 are rotatably connected and mutually axially sliding and limited. In this embodiment, a rotation axis is formed between the pressure bottle 2 and the shoulder sleeve 1. This rotation axis is coaxial with the axis of the shoulder sleeve 1. Axial sliding is sliding along the axis direction, and axial rotation is rotation about the axis.

[0041] Specifically, a pressure bottle 2 is installed at the connecting end 18 of the shoulder sleeve 1. An annular snap-fit ​​part 181 is formed on the inner circumference of the connecting end 18, and a snap-fit ​​part 21 is formed on the outer circumference of the pressure bottle 2. The snap-fit ​​part 21 is embedded in the snap-fit ​​part 181, which can form a rotational connection and can form an axial sliding limit to prevent the pressure bottle 2 from detaching from the shoulder sleeve 1.

[0042] A linkage sleeve 91 is fixedly connected to the cover 9. A linkage member 8 is installed between the linkage sleeve 91 and the connecting cylinder 12. The linkage member 8 and the connecting cylinder 12 are axially slidably connected and mutually axially rotated and limited. The linkage member 8 is also threadedly connected to the linkage sleeve 91. When the pressure bottle 2 is rotated, the pressure bottle 2 rotates relative to the shoulder sleeve 1. The linkage member 8 does not rotate with the pressure bottle 2. The linkage member 8 and the linkage sleeve 91 generate threaded transmission. During the threaded transmission, the linkage member 8 will slide axially relative to the linkage sleeve 91.

[0043] A first pressing part 83 is fixedly connected to the linkage 8, and the first pressing part 83 can be mutually pressed and adapted with the second pressing part 102. When the linkage 8 is threaded towards the cover 9, the first pressing part 83 can abut against the second pressing part 102, which can press the valve core 101. After the valve core 101 is pressed, the solvent in the pressure bottle 2 can be sprayed out from the liquid outlet 1011 of the valve core 101 under the action of pressurized gas.

[0044] Reference Figure 6As shown, the outlet end 1011 of the valve core 101 extends into the second end 122 of the connecting cylinder 12. The outlet end 1011 of the valve core 101 can rotate and slide axially relative to the second end 122 of the connecting cylinder 12. The sealing sleeve 7 is a sealing connecting sleeve. The sealing sleeve 7 is embedded in the second end 122 of the connecting cylinder 12, and the outer periphery of the sealing sleeve 7 is sealed to the inside of the connecting cylinder 12. The outlet end 1011 of the valve core 101 is inserted into the inner periphery of the sealing sleeve 7 to achieve mutual sealing and to achieve relative axial rotation and axial sliding, thereby adapting to the movement needs of the valve core 101.

[0045] Specifically, refer to Figure 6 , Figure 7 As shown, the linkage 8 is sleeved outside the connecting cylinder 12. A first guide slide 13 is provided on the outer periphery of the connecting cylinder 12, and a second guide slide 81 is provided on the inner periphery of the linkage 8. The first guide slide 13 and the second guide slide 81 are slidably connected to each other. The first guide slide 13 and the second guide slide 81 are sliders or grooves arranged along the axial direction of the connecting cylinder 12, which can form axial sliding guidance and can rotate relative to each other.

[0046] A threaded portion 3 82 is provided on the outer periphery of the linkage component 8, and a threaded portion 4 92 is provided on the inner periphery of the linkage sleeve 91. The linkage sleeve 91 is sleeved on the outside of the linkage component 8, and the threaded portion 3 82 and the threaded portion 4 92 are threadedly connected to each other. The linkage sleeve 91 is sleeved on the linkage component 8 to realize threaded transmission, and thus the axial relative displacement adjustment can be realized during the rotation of the pressure bottle 2.

[0047] Furthermore, the first pressing part 83 is located on the inner circumference of the linkage member 8, forming an annular protrusion on the inner circumference of the linkage member 8. A clearance hole 84 is provided in the middle of the first pressing part 83, allowing the valve core 101 to pass through. After the valve core 101 passes through the clearance hole 84, the second pressing part 102 of the valve core 101 can come into close contact with the first pressing part 83. During the axial movement of the linkage member 8, the first pressing part 83 and the second pressing part 102 can press against each other axially to achieve transmission.

[0048] Reference Figures 4-6 As shown, the first end 121 of the connecting cylinder 12 is located inside the storage bottle 3, and a material holder 5 is installed at the first end 121 of the connecting cylinder 12. The material holder 5 is embedded in the first end 121 of the connecting cylinder 12, and a limiting part 14 is fixedly connected inside the connecting cylinder 12. The limiting part 14 can press against and limit the material holder 5. A through hole 141 is provided in the limiting part 14, which connects the first end 121 and the second end 122 of the connecting cylinder 12. In order to realize solvent flow at the material holder 5, a guide groove 52 is provided in the material holder 5, which connects the storage bottle 3 and the through hole 141, so that the solvent in the pressure bottle 2 can flow into the storage bottle 3.

[0049] Reference Figure 5 , Figure 6As shown, in this embodiment, the freeze-dried material 6 is pre-processed into a spherical shape. A spherical recess 51 is formed on the upper side of the material holder 5, the shape of which is adapted to the freeze-dried material 6. The freeze-dried material 6 is spherical and can be placed in the recess 51 of the material holder 5. The material holder 5 has several guide grooves 52, which are located on the outer periphery of the material holder 5.

[0050] When the pressurized gas carrying the solvent is ejected from the pressure bottle 2, the gas and solvent are ejected from the guide groove 52, which can impact the lower outer peripheral surface of the freeze-dried material 6, causing the freeze-dried material 6 to rotate in the recess 51 of the material seat 5, which can accelerate the mixing and contact between the freeze-dried material 6 and the solvent, and accelerate the dissolution.

[0051] Reference Figure 10 As shown, the guide channel 52 is inclined, tilting from bottom to top towards the outer periphery, forming an inclination angle α. The inclination angle α ranges from 15° to 60°. When the gas and solvent are ejected from the guide channel 52, they can form a jet in the outward direction. The inclined jet angle can stably and effectively drive the lyophilized material 6 to rotate, accelerating the contact and dissolution of the lyophilized material 6 with the reagent.

[0052] In this embodiment, the storage bottle 3 can be pre-vacuumed, creating a relatively vacuum environment inside the storage bottle 3. The freeze-dried material 6 is in an oxygen-free drying environment, which can preserve the freeze-dried material 6 for a long time.

[0053] Reference Figure 5 , Figure 8 , Figure 9 As shown, a vent 34 is provided in the storage bottle 3, and a sealing element 120 is provided at the vent 34. The sealing element 120 elastically presses against the outside of the vent 34 and can seal the vent 34. The sealing element 120 can achieve a one-way seal for the vent 34, that is, when the external pressure of the storage bottle 3 is low, the air inside the storage bottle 3 can push the sealing element 120 outward, which can open the vent 34 and discharge it outward from the vent 34; when the internal and external pressures of the storage bottle 3 are relatively balanced, or when the external pressure of the storage bottle 3 is high, the sealing element 120 can seal and cover the vent 34. With the help of air pressure and the elasticity of the sealing element 120 itself, the vent 34 is kept closed, which can maintain the vacuum environment inside the storage bottle 3.

[0054] Reference Figure 8 As shown, the sealing element 120 is annular and is fitted over the storage bottle 3 to form an interference fit. The annular sealing element 120 is elastic, and under its own elastic force, it maintains the pressure between the sealing element 120 and the storage bottle 3, thus forming a pressure seal outside the vent 34.

[0055] To maintain the installation stability of the seal 120, an annular groove 33 is provided on the outside of the storage bottle 3, and the seal 120 can be embedded in the annular groove 33. The vent 34 is located at the annular groove 33, and after the seal 120 is embedded in the annular groove 33, it can seal the vent 34.

[0056] Reference Figure 1 , Figure 2 , Figure 5 , Figure 9 As shown, the dual-chamber storage and dissolution device in this embodiment also includes an outer cover 4, which controls the opening and closing of the storage bottle 3. An outlet 32 ​​is provided on the side of the storage bottle 3 facing away from the shoulder sleeve 1. The outer cover 4 is installed on the outside of the storage bottle 3, and the outer cover 4 can close the outlet 32 ​​after it is closed.

[0057] A limiting groove 41 is formed inside the outer cover 4 at a position corresponding to the outlet 32, and a sealing gasket 110 is embedded in the limiting groove 41. The end of the outer cover 4 extends to the shoulder sleeve 1 and can be threadedly connected to the connecting end 17 of the shoulder sleeve 1. When the outer cover 4 is closed, the outer cover 4 is tightened by the thread, and the outer cover 4 and the outlet 32 ​​can press against each other at the sealing gasket 110 to achieve a seal.

[0058] Specifically, a threaded portion 171 is provided on the inner circumference of the connecting end 17, and a threaded portion 42 is provided on the outer circumference of the end of the outer cover 4. The end of the outer cover 4 extends into the connecting end 17 of the shoulder sleeve 1 to achieve a threaded connection. At the same time, when the threads of the outer cover 4 are tightened, the outer cover 4 will be subjected to a downward force, which can form a sealing pressure at the outlet 32, pressing the sealing gasket 110 to achieve a seal.

[0059] Reference Figure 2 , Figure 6 As shown, the connecting tube 12 and the shoulder sleeve 1 are fixedly connected by an annular partition portion 11. An interface 31 is formed at the end of the storage bottle 3 facing the shoulder sleeve 1, and the interface 31 is open. A connecting sleeve portion 15 is fixed to the partition portion 11. The connecting sleeve portion 15 has an annular structure and its shape and size match that of the interface 31, allowing the interface 31 to be fitted onto the connecting sleeve portion 15. After connection, the interface 31 and the connecting sleeve portion 15 can be fixed and sealed by means of bonding or ultrasonic welding.

[0060] In addition, a sealing part 16 is formed on the side of the partition portion 11 facing the storage bottle 3. The sealing part 16 has an annular structure and is adapted to the end face of the interface 31. When the storage bottle 3 is installed, the end face of the interface 31 and the sealing part 16 fit together, forming a curved gap at the connection, which can increase the contact area of ​​the connection and thus improve the strength and stability of the connection.

[0061] Reference Figure 6 , 7As shown, a sealing ring 108 and a spring 106 are also installed inside the press valve 10. A portion of the valve core 101 is located inside the valve cavity of the press valve 10, and an annular protrusion 103 is fixedly connected to the outer periphery of the valve core 101. A central hole 105 is opened at the upper end of the valve core 101. The central hole 105 is a blind hole opened from top to bottom. A second through hole 104 is opened on the outer periphery of the valve core 101. The second through hole 104 is located on the upper side of the annular protrusion 103 and communicates with the central hole 105.

[0062] Spring 106 elastically presses against the lower side of the annular protrusion 103, pushing the annular protrusion 103 against the sealing ring 108. In the static state, the second through hole 104 is located on the inner circumference of the sealing ring 108, and the inner circumferential wall of the sealing ring 108 can seal and cover the second through hole 104. At this time, the press valve 10 is closed. (Refer to...) Figure 6 As shown. When the valve core 101 is pressed down, the valve core 101 and the sealing ring 108 move axially, and the second through hole 104 will protrude from the inner circumference of the sealing ring 108, enabling communication with the lower side of the valve cavity, thereby allowing the push valve 10 to be opened. (Refer to...) Figure 7 As shown.

[0063] Reference Figure 9 As shown, a liquid guide tube 107 is connected to the lower end of the press valve 10. The liquid guide tube 107 extends downward to the bottom of the pressure bottle 2. Under the action of high pressure gas, the reagent in the pressure bottle 2 can be discharged as much as possible.

[0064] This embodiment discloses a method of use, employing the dual-chamber storage and dissolution device as described in the above embodiment. During packaging, the storage bottle 3 contains spherical freeze-dried material 6 (or the corresponding substance to be mixed), and the storage bottle 3 is evacuated to -0.05MPa to -0.1MPa. The vacuum environment inside the storage bottle 3 allows the freeze-dried material 6 (or other substances to be mixed) to be stored in a relatively oxygen-free and dry environment, enabling long-term preservation. The pressure bottle 2 contains the solvent and is filled with high-pressure gas.

[0065] In use, the pressure bottle 2 and the shoulder sleeve 1 rotate axially relative to each other, and the linkage 8 is threaded towards the cover 9. The first pressing part 83 abuts against the second pressing part 102, which can press the valve core 101. After the valve core 101 is pressed down, the pressing valve 10 will be opened, and the high-pressure gas stored in the pressure bottle 2 will push the solvent out from the liquid outlet 1011 of the valve core 101. The solvent enters the storage bottle 3, and the lyophilized material 6 or other substances to be mixed) is mixed and dissolved in the solvent to form a mixed reagent.

[0066] The mixed reagent can be stored in the storage bottle 3 for user use. When needed, the user can open the outer cap 4 and open the outlet 32 ​​of the storage bottle 3, from which the mixed reagent can be poured out for use; after use, the outer cap 4 can be closed again.

[0067] By employing the dual-chamber storage and dissolution device in this embodiment, the lyophilized material 6 (or other substances to be mixed) and the solvent can be stored separately in two bottles, enabling separate storage and long-term storage and preservation. High-pressure gas can quickly press the reagent into the storage bottle 3, achieving rapid mixing and dissolution of the lyophilized material 6 and the solvent, which is convenient for users.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
