The storage bottle and the pressure bottle are respectively installed at both ends of the shoulder sleeve. The pressure bottle is used to store a solvent and a pressure gas. The pressure bottle is provided with a cover body equipped with a pressing valve. The pressing valve includes a valve core capable of pressing out liquid. The valve core has a second pressing portion and a liquid outlet end.

[0007] A connecting cylinder is fixedly connected inside the shoulder sleeve. The first end of the connecting cylinder communicates with the storage bottle, and the second end of the connecting cylinder is hermetically connected 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 slidably limited to each other. The cover body is fixedly connected with a linkage sleeve. The device further includes a linkage member. The linkage member is axially slidably connected to the connecting cylinder and is axially rotationally limited to each other. The linkage member is threadedly connected to the linkage sleeve and is provided with a first pressing portion. When the linkage member is threadedly adjusted towards the cover body, the first pressing portion abuts against the second pressing portion, and the valve core can be pressed.

[0009] The present invention is further configured such that the storage bottle is provided with an exhaust hole, and a sealing member is provided at the exhaust hole. The sealing member elastically presses against the outside of the exhaust hole and can seal the exhaust hole.

[0010] The present invention is further configured such that the seal is annular and sleeved outside the storage bottle; an annular groove is formed outside the storage bottle, and the seal 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 a material seat is installed. A plurality of diversion grooves are formed on the outer periphery of the material seat, and the diversion grooves communicate the storage bottle and the liquid outlet end of the valve core; a spherical concave portion is formed on the upper side of the material seat.

[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 axially rotate and axially slide relative to the second end of the connecting cylinder.

[0014] The present invention is further configured such that the linkage member is sleeved outside the connecting cylinder. A first guiding and sliding portion is provided on the outer periphery of the connecting cylinder, and a second guiding and sliding portion is provided on the inner periphery of the linkage member. The first guiding and sliding portion and the second guiding and sliding portion are slidably connected to each other; a third threaded portion is provided on the outer periphery of the linkage member, and a fourth threaded portion is provided on the inner periphery of the linkage sleeve. The third threaded portion and the fourth threaded portion are threadedly connected to each other.

[0015] The present invention is further configured to further include an outer cover. An outlet is formed on the side of the storage bottle facing away from the shoulder sleeve. The outer cover is installed outside 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 through an annular partition portion. An interface is formed at one end of the storage bottle facing the shoulder sleeve; the partition portion is fixedly provided with a connecting sleeve portion, and the connecting sleeve portion and the interface are hermetically sleeved with each other.

[0017] The present invention further provides a usage method of the double-chamber storage and dissolution device as described above. During packaging, the storage bottle stores freeze-dried materials and is evacuated, and the pressure bottle stores a solvent and is filled with high-pressure gas;

[0018] During use, the pressure bottle and the shoulder sleeve rotate axially relative to each other. The linkage member is threadedly adjusted towards the cover body direction, the first pressing portion and the second pressing portion are abutted against each other, the valve core is pressed, and the high-pressure gas stored in the pressure bottle pushes the solvent to spray out from the liquid outlet end of the valve core. The solvent enters the storage bottle, and the freeze-dried materials are mixed into the solvent to form a mixed reagent.

[0019] In summary, the present invention has the following beneficial effects:

[0020] By adopting two bottles, namely a pressure bottle and a storage bottle, the solvent and the substance to be mixed can be stored separately in the two bottles, achieving separate storage and enabling long-term storage and preservation. The reagent can be quickly pressed into the storage bottle by high-pressure gas, realizing the rapid mixing and dissolution of the substance to be mixed and the solvent, which is convenient for users to use.

[0021] The solvent is stored in the pressure bottle along with pressurized gas. During use, by rotating the pressure bottle, relative rotation will occur between the pressure bottle and the shoulder sleeve, driving the linkage to generate threaded linkage. The linkage and the pressing valve will approach each other, being able to press down the valve core of the pressing valve. The solvent in the pressure bottle can be ejected from the liquid outlet end of the valve core under the action of the pressurized gas. The solvent flows through the connecting cylinder and enters the storage bottle, where it mixes with the substance to be mixed, and the substance to be mixed can be mixed into the solvent to form a mixed reagent.

[0022] The lyophilized material is stored in the storage bottle. By setting the lyophilized material as spherical and supporting it with a seat having a spherical depression, the lyophilized material can rotate freely on the seat. By opening a diversion groove, and the diversion groove being inclined and distributed on the outer periphery of the seat, the solvent and gas ejected from the liquid outlet end of the valve core can be ejected from the diversion groove, generating a jet on the spherical lyophilized material, driving the lyophilized material to rotate self - sufficiently and accelerating the dissolution of the lyophilized material.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] This embodiment discloses a dual-chamber storage and dissolution device. Referring to Figures 1-10 as shown, it 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.

[0036] Referring to Figure 2 , Figure 3 as shown, the pressure bottle 2 is provided with a cover body 9. The cover body 9 is installed with a pressing valve 10. The pressing valve 10 includes a valve core 101 capable of pressing out liquid. The valve core 101 has a second pressing part 102 and a liquid outlet end 1011. A connecting cylinder 12 is fixedly connected inside the shoulder sleeve 1. The first end 121 of the connecting cylinder 12 communicates with the storage bottle 3, and the second end 122 of the connecting cylinder 12 is hermetically connected to the liquid outlet end 1011 of the valve core 101 through a sealing sleeve 7.

[0037] The solvent is stored in the pressure bottle 2, and a pressurized gas is also stored therein. The storage bottle 3 stores substances to be mixed, which can be freeze-dried materials, powders, or other reagents, etc. In this embodiment, the freeze-dried materials are taken as an example for detailed description.

[0038] During use, by pressing the valve core 101, the solvent in the pressure bottle 2 can be ejected from the liquid outlet end 1011 of the valve core 101 under the action of the pressurized gas; the solvent flows through the connecting cylinder 12 and enters the storage bottle 3, where the solvent is mixed with the freeze-dried materials 6, and the freeze-dried materials 6 are mixed and dissolved in the solvent to form a mixed reagent.

[0039] Refer to Figure 3 , Figure 5 , Figure 6 As shown in

[0040] Specifically, the pressure bottle 2 is installed at the second connecting end 18 of the shoulder sleeve 1. An annular clamping portion one 181 is formed on the inner circumference of the second connecting end 18, and a clamping portion two 21 is formed on the outer circumference of the pressure bottle 2. The clamping portion two 21 is embedded in the clamping portion one 181, which can form a rotational connection and can also form an axial sliding limit to prevent the pressure bottle 2 from detaching from the shoulder sleeve 1.

[0041] A linkage sleeve 91 is fixedly connected to the cover body 9. A linkage member 8 is installed between the linkage sleeve 91 and the connecting cylinder 12. The linkage member 8 is axially slidably connected to the connecting cylinder 12 and is axially rotationally limited to each other. 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, and the linkage member 8 does not follow the pressure bottle 2 to rotate. The linkage member 8 and the linkage sleeve 91 generate a threaded drive, and during the threaded drive process, the linkage member 8 will axially slide relative to the linkage sleeve 91.

[0042] A first pressing portion 83 is fixedly connected to the linkage member 8, and the first pressing portion 83 can be mutually pressed and adapted to the second pressing portion 102. When the linkage member 8 is threadedly adjusted towards the cover body 9, the first pressing portion 83 can abut against the second pressing portion 102 to press the valve core 101. After pressing the valve core 101, the solvent in the pressure bottle 2 can be ejected from the liquid outlet end 1011 of the valve core 101 under the action of the pressurized gas.

[0043] Refer to Figure 6As shown, the liquid outlet end 1011 of the valve core 101 extends into the second end 122 of the connecting cylinder 12, and the liquid outlet end 1011 of the valve core 101 can axially rotate and axially slide 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 sealingly connected to the inside of the connecting cylinder 12; the liquid outlet end 1011 of the valve core 101 is inserted into the inner periphery of the sealing sleeve 7 to achieve mutual sealing, and can achieve relative axial rotation and axial sliding, and thus can meet the movement requirements of the valve core 101.

[0044] Specifically, referring to Figure 6 、 Figure 7 As shown, the linkage member 8 is sleeved outside the connecting cylinder 12. A first guiding part 13 is arranged on the outer periphery of the connecting cylinder 12, and a second guiding part 81 is arranged on the inner periphery of the linkage member 8. The first guiding part 13 and the second guiding part 81 are slidably connected to each other. The first guiding part 13 and the second guiding part 81 are sliders or chutes arranged along the axial direction of the connecting cylinder 12, which can form axial sliding guidance and can also rotate relative to each other.

[0045] A third threaded part 82 is arranged on the outer periphery of the linkage member 8, and a fourth threaded part 92 is arranged on the inner periphery of the linkage sleeve 91. The linkage sleeve 91 is sleeved outside the linkage member 8, and the third threaded part 82 and the fourth threaded part 92 are threadedly connected to each other. When the linkage sleeve 91 is sleeved on the linkage member 8, screw drive can be achieved, and thus axial relative displacement adjustment can be achieved during the rotation of the pressure bottle 2.

[0046] In addition, a first pressing part 83 is located on the inner periphery of the linkage member 8, protruding annularly from the inner periphery of the linkage member 8. A relief hole 84 is provided at the middle position of the first pressing part 83, through which the valve core 101 can pass. After the valve core 101 passes through the relief hole 84, a second pressing part 102 of the valve core 101 can be in 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 axially press against each other to achieve transmission.

[0047] Referring to Figures 4-6 As shown, the first end 121 of the connecting cylinder 12 is located inside the storage bottle 3, and a material seat 5 is installed at the first end 121 of the connecting cylinder 12. The material seat 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 seat 5. A first through hole 141 is provided in the limiting part 14, and the first through hole 141 communicates with the first end 121 and the second end 122 of the connecting cylinder 12; in order to achieve solvent flow at the material seat 5, a diversion groove 52 is provided in the material seat 5, and the diversion groove 52 communicates with the storage bottle 3 and the first through hole 141, so that the solvent in the pressure bottle 2 can flow into the storage bottle 3.

[0048] Referring to Figure 5 、 Figure 6As shown in the figure, in this embodiment, the freeze-dried material 6 is pre-processed into a spherical shape. A spherical concave portion 51 is formed on the upper side of the material seat 5, and its shape is adapted to the freeze-dried material 6. The freeze-dried material 6 is spherical and can be placed at the concave portion 51 of the material seat 5. The material seat 5 is provided with a number of diversion grooves 52, and they are located on the outer periphery of the material seat 5.

[0049] When the pressurized gas in the pressure bottle 2 carries the solvent and sprays out, the gas and the solvent spray out from the diversion grooves 52, which can impact the outer peripheral surface of the lower side of the freeze-dried material 6, drive the freeze-dried material 6 to rotate in the concave portion 51 of the material seat 5, accelerate the mixing and contact between the freeze-dried material 6 and the solvent, and accelerate dissolution.

[0050] Refer to Figure 10 As shown in the figure, the diversion grooves 52 are arranged in an inclined shape, inclined upward and outward, forming an inclination angle a, and the range of the inclination angle a is 15° to 60°. When the gas and the solvent spray out from the diversion grooves 52, an outward jet can be formed. The inclined jet angle can stably and effectively drive the freeze-dried material 6 to rotate and accelerate the contact and dissolution between the freeze-dried material 6 and the reagent.

[0051] In this embodiment, the storage bottle 3 can be pre-evacuated, and a relatively vacuum environment is formed inside the storage bottle 3. The freeze-dried material 6 is in an oxygen-free and dry environment, which can preserve the freshness of the freeze-dried material 6 for a long time.

[0052] Refer to Figure 5 、 Figure 8 、 Figure 9 As shown in the figure, an exhaust hole 34 is opened in the storage bottle 3, and a seal 12 is arranged at the exhaust hole 34. The seal 12 elastically presses against the outside of the exhaust hole 34 and can seal the exhaust hole 34. The seal 12 can achieve one-way sealing of the exhaust hole 34, that is, when the external pressure of the storage bottle 3 is small, the air inside the storage bottle 3 can push the seal 12 outward and open the exhaust hole 34 to discharge outward from the exhaust hole 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 large, the seal 12 can seal and cover the exhaust hole 34, and with the help of air pressure and the elasticity of the seal 12 itself, keep the exhaust hole 34 closed and maintain the vacuum environment inside the storage bottle 3.

[0053] Refer to Figure 8 As shown in the figure, the seal 12 is annular and sleeved outside the storage bottle 3 to form an interference fit. The annular seal 12 has elasticity, and under the action of its own elastic force, it maintains the pressure between the seal 12 and the storage bottle 3 and can form a pressure seal outside the exhaust hole 34.

[0054] To maintain the installation stability of the seal 12, a ring groove 33 is provided outside the storage bottle 3, and the seal 12 can be embedded in the ring groove 33. The exhaust hole 34 is provided at the position of the ring groove 33. After the seal 12 is embedded in the ring groove 33, it can just seal the exhaust hole 34.

[0055] Refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 9 As shown, a double-chamber storage and dissolution device in this embodiment further includes an outer cover 4, and the outer cover 4 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 outside the storage bottle 3, and the outer cover 4 can close the outlet 32 after being closed.

[0056] At a position corresponding to the outlet 32 inside the outer cover 4, a limiting groove 41 is formed, and a gasket 11 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 one 17 of the shoulder sleeve 1. When the outer cover 4 is closed, by screwing the outer cover 4 tightly, the outer cover 4 and the outlet 32 can be pressed against each other at the gasket 11 to achieve sealing.

[0057] Specifically, a thread portion one 171 is provided on the inner circumference of the connecting end one 17, and a thread portion two 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 one 17 of the shoulder sleeve 1 to achieve threaded connection. At the same time, when the outer cover 4 is screwed tightly, the outer cover 4 will receive a downward force, and a sealing pressure can be formed at the outer cover 4 and the outlet 32, and the gasket 11 is pressed tightly to achieve sealing.

[0058] Refer to Figure 2 、 Figure 6 As shown, the connecting cylinder 12 and the shoulder sleeve 1 are fixedly connected through an annular partition portion 11. One end of the storage bottle 3 facing the shoulder sleeve 1 forms an interface 31, and the interface 31 is in an open shape. The partition portion 11 is fixed with a connecting sleeve portion 15. The connecting sleeve portion 15 has an annular structure and is matched with the shape and size of the interface 31, and the interface 31 can be sleeved with the connecting sleeve portion 15. After the interface 31 and the connecting sleeve portion 15 are connected, they can be fixed and sealed by bonding or ultrasonic welding, etc.

[0059] In addition, on the side of the partition portion 11 facing the storage bottle 3, a sealing portion 16 is further formed. The sealing portion 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 is fitted with the sealing portion 16, and a bending gap is formed at the connection, which can increase the contact area of the connection, thereby improving the strength and stability of the connection.

[0060] Refer to Figure 6 、 7As shown, a sealing ring 108 and a spring 106 are also installed inside the pressing valve 10. Part of the valve core 101 is located in the valve cavity of the pressing valve 10, and an annular convex portion 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 through hole two 104 is opened on the outer periphery of the valve core 101. The through hole two 104 is located above the annular convex portion 103 and communicates with the central hole 105.

[0061] The spring 106 elastically presses against the lower side of the annular convex portion 103 and can push the annular convex portion 103 to abut against the sealing ring 108. In the static state, the through hole two 104 is located inside the inner circumference of the sealing ring 108, and the inner circumferential wall of the sealing ring 108 can seal and cover the through hole two 104. At this time, the pressing 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. The through hole two 104 will be exposed from the inner circumference of the sealing ring 108 and can communicate with the lower side of the valve cavity, so that the pressing valve 10 can be opened. Refer to Figure 7 As shown.

[0062] Refer to Figure 9 As shown, a liquid guide pipe 107 is connected to the lower end of the pressing valve 10. The liquid guide pipe 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.

[0063] This embodiment discloses a usage method. Using the double-chamber storage and dissolution device in the above-mentioned embodiment, during packaging, spherical freeze-dried materials 6 (or corresponding substances to be mixed) are stored in the storage bottle 3, and the storage bottle 3 is evacuated to -0.05 MPa to -0.1 MPa. The vacuum environment in the storage bottle 3 can store the freeze-dried materials 6 (or other substances to be mixed) in a relatively oxygen-free and dry environment, enabling long-term preservation. The pressure bottle 2 stores the solvent and is filled with high-pressure gas.

[0064] During use, the pressure bottle 2 rotates axially relative to the shoulder sleeve 1, and the linkage member 8 is thread-adjusted towards the direction of the cover body 9. The first pressing portion 83 abuts against the second pressing portion 102, and can press the valve core 101. After the valve core 101 is pressed down, the pressing valve 10 will be opened. The high-pressure gas stored in the pressure bottle 2 pushes the solvent to spray out from the liquid outlet end 1011 of the valve core 101. The solvent enters the storage bottle 3, and the freeze-dried materials 6 or other substances to be mixed) are mixed and dissolved in the solvent to form a mixed reagent.

[0065] The mixed reagent can be stored in the storage bottle 3 for the user to use. When in need of use, the user can open the outer cover 4 and open the outlet 32 of the storage bottle 3. The mixed reagent can be poured out from the outlet 32 for use; after use, the outer cover 4 can be closed again.

[0066] By adopting the double-chamber storage and dissolution device in this embodiment, the freeze-dried material 6 (or other substances to be mixed) and the solvent can be stored separately in two bottles, enabling separate storage, long-term storage, and preservation. The reagent can be quickly pressed into the storage bottle 3 by high-pressure gas to achieve rapid mixing and dissolution of the freeze-dried material 6 and the solvent, facilitating user operation.
