Description

[0001] The present application claims the priority of patent application numbered 202210519846.0, filed on May 13, 2022, and entitled “A convenient solid essence protection device”. Technical Field

[0002] The present invention belongs to the technical field of solid essence packaging and use devices, and in particular relates to a convenient-to-use solid essence protection device and a use method thereof. Background Art

[0003] Solid essences generally refer to materials that have been solidified into solid form by some means of drying, including active ingredients. Since they are basically in anhydrous state, there is no need to worry about the active ingredients being deteriorated or oxidized due to water environment. Therefore, there is no need to add preservatives, antibacterial agents and other additives that may have side effects on the human body or skin.

[0004] Since solid essences are required to dissolve quickly in water during use, they are often very brittle. A typical example is freeze-dried preparations. The solid essences after molding are easily broken and powdered during transportation and storage, which not only affects the integrity and appearance of the shape, but also causes the loss of the essence. At the same time, when applying the essence, many users inevitably need to touch and knead the essence with their hands before applying it, which is not only inconvenient but also easy to cause contact contamination. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a convenient solid essence protection device and a method for using the same, comprising a sleeve with a vertical axis, wherein a local section of the sleeve cavity along the axial direction is filled with a solid essence such as a freeze-dried preparation that can be quickly dissolved in water,

[0006] A moisture absorbing mechanism is disposed below the solid essence in the sleeve cavity and can slide along the axial direction of the sleeve. The moisture absorbing mechanism includes a moisture absorbing head. When the moisture absorbing mechanism moves upward in the sleeve cavity, the moisture absorbing head contacts the solid essence and dissolves the solid essence. The dissolved solid essence is pushed upward out of the sleeve through the opening at the top of the sleeve.

[0007] As a preferred embodiment, the moisture absorption head is formed of a material that does not make the skin feel uncomfortable when in contact with the skin and has the ability to load liquid, such as a sponge. This type of material has a strong moisture absorption capacity and a large amount of liquid absorption. After absorbing moisture, it contacts and moistens the solid essence. The essence disintegrates and dissolves and continues to be loaded on it. It has good elasticity and high softness, and can be directly applied to the skin surface. Apply the essence on it to the skin.

[0008] Preferably, the solid essence is provided with a through hole connecting the upper and lower surfaces thereof.

[0009] As a preferred embodiment, the moisture absorption mechanism further comprises a seat body, and the moisture absorption head is arranged on the top of the seat body.

[0010] Furthermore, a channel connecting the upper and lower surfaces of the base body is provided in the base body, and liquid is transmitted from bottom to top through the channel to the moisture absorbing head to moisten the moisture absorbing head.

[0011] Preferably, a limiting mechanism is provided at the top opening of the sleeve to prevent the seat body from leaving the sleeve upwards, for example, the horizontal radial dimension of the sleeve cavity near the top opening of the sleeve is designed to decrease from bottom to top along the vertical direction.

[0012] As a preferred embodiment, the seat body is in the sleeve cavity and can slide along the axial direction of the sleeve. A locking mechanism is provided on the sleeve cavity wall, which can temporarily block the seat body from moving upward in the sleeve cavity, thereby preventing the moisture absorption head from pushing up against the solid essence.

[0013] As a preference:

[0014] The locking mechanism may be a frosted section arranged on the annular cavity wall of the sleeve below the solid essence. When the seat body slides in the sleeve cavity, the relative friction between the seat body and the frosted section is greater than the relative friction between the seat body and other areas of the sleeve cavity wall except the frosted section.

[0015] The locking mechanism may also include a first locking ring formed by a horizontal annular inward protrusion on the wall of the sleeve below the solid essence, and a second locking ring formed by a horizontal annular outward protrusion on the seat body. The inner ring diameter of the first locking ring is slightly smaller than the outer ring diameter of the second locking ring. In a natural state, the first locking ring blocks the second locking ring from passing through, thereby blocking the moisture absorption head from pushing up to the solid essence.

[0016] A liquid supply device is detachably mounted below the seat body, and a connecting tube is vertically extended upward from the liquid supply device. When the sleeve covers the top opening of the connecting tube through the seat body, in a natural state, the sleeve is prevented from sliding relative to the seat body to the solid essence being pushed up by the moisture absorption head through the clamping mechanism; when the sleeve itself is pressed down, the seat body is forced open by the reaction force of the connecting tube on the seat body, so that the moisture absorption head is pushed upward to the solid essence, and the liquid supply device sequentially supplies liquid to the moisture absorption head through the connecting tube and the hole.

[0017] As a preference, the liquid feeding device is an extrusion type liquid feeding device, comprising a mounting tube with a vertical axis, a liquid storage tube coaxially inserted upward in the mounting tube and capable of sliding back and forth in the mounting tube cavity, and a connecting tube for connecting the hole and the mounting tube cavity extending vertically upward from the top of the mounting tube.

[0018] A discharge pump mechanism is fixedly installed on the top of the liquid storage cylinder. The discharge pump mechanism includes a cover plate tightly covering the top pipe opening of the liquid storage cylinder. A transfer cavity is fixedly connected to the center of the lower plate surface of the cover plate (integrally formed with the cover plate). The transfer cavity is equivalent to extending vertically downward from the cover plate into the tube cavity of the liquid storage cylinder.

[0019] A one-way valve is installed at the bottom of the transfer chamber, and a first piston is embedded in the transfer chamber and can slide back and forth in the transfer chamber. The discharge pipe with a vertical axis can slide back and forth on the first piston. At the same time, the discharge pipe passes through the cover plate vertically upward along its own length and is connected with the bottom opening of the connecting pipe. The discharge pipe can slide back and forth on the cover plate. The bottom end of the discharge pipe is sealed. A discharge port connecting the discharge pipe cavity and the outside (i.e., the cavity of the transfer chamber) is provided on the discharge pipe body, and the discharge port is blocked by the first piston.

[0020] The tube body at the top of the discharge tube extends outward in a horizontal ring direction to form a circle of support plates. A spring with a vertical axial direction is provided between the support plate and the cover plate as an elastic support. The spring is coaxially sleeved on the tube section of the discharge tube between the support plate and the cover plate.

[0021] A second piston is embedded near the bottom of the liquid storage tube cavity and can slide back and forth in the liquid storage tube cavity. An air cavity is formed between the second piston and the bottom of the liquid storage tube cavity. A vent hole connecting the air cavity and the external atmosphere is opened at the bottom of the liquid storage tube.

[0022] When the liquid storage cylinder slides vertically upward in the cavity of the installation cylinder, the top of the cavity of the installation cylinder presses down on the discharge pipe, and the liquid in the transfer cavity is pressed upward through the discharge pipe, the connecting pipe, and the channel to the moisture absorption head to achieve wetting.

[0023] Furthermore, the tube body at the bottom end of the discharge pipe horizontally protrudes outward in an annular direction to form a circle for preventing the first piston from downwardly escaping from the limiting portion of the discharge pipe.

[0024] The present invention also provides a method for using the solid essence protection device: driving the moisture absorption mechanism to move upward without stopping in the sleeve cavity until the moisture absorption head fully pushes the dissolved solid essence upward out of the sleeve through the opening at the top of the sleeve.

[0025] When the moisture absorbing mechanism moves upward without stopping in the sleeve cavity, the moving speed is in the range of 0 to 1 m / s, preferably 0.5 to 0.92 m / s. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] It should be noted that the terms "upper", "lower", "side wall", "horizontal", "vertical", "top" and "bottom" used in the description of the present invention refer to the attached Figure 1 , 3 In the directions of , 4, 6, 7, 8, 9, 10, 11, and 13, "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0041] Example 1

[0042] As attached Figure 1 As shown, the easy-to-use solid essence protection device of the present invention first comprises a sleeve 1 with a vertical axis, and a limiting structure 13 is set at the top opening of the sleeve 1: the horizontal radial dimension of the sleeve 1 cavity near the top opening of the sleeve 1 gradually decreases from bottom to top along the vertical direction, and the portion of the sleeve 1 cavity below the limiting structure is a regular cylindrical inner cavity wall,

[0043] In the barrel cavity of the sleeve 1, a local section along the axial direction of the sleeve 1 is filled with a solid essence 2, which is a freeze-dried preparation, and a through hole 21 connecting the upper and lower surfaces of the freeze-dried preparation is opened on the freeze-dried preparation. With reference to the prior art, the freeze-dried preparation is assembled in situ into the sleeve 1: the sleeve 1 is inverted and inserted into the positioning groove cavity to fit in, and the filling needle tube vertical in the length direction is inserted vertically downward into the barrel cavity of the sleeve 1 and close to the bottom of the positioning groove cavity, and this position is maintained, and an appropriate amount of aqueous pre-mixing liquid of the freeze-dried preparation is filled into the barrel cavity of the sleeve 1 through the filling needle tube to the corresponding liquid level height, and after sufficient freeze-drying, the filling device is moved upward to pull out the filling needle tube, that is, the corresponding through hole 21 is left on the obtained freeze-dried preparation, and then the sleeve 1 is taken out from the positioning groove and the sleeve 1 is turned over and reset, so that the sleeve 1 filled with the freeze-dried preparation attached near the top opening of the barrel cavity is obtained.

[0044] A moisture absorption mechanism is also provided in the barrel cavity of the sleeve 1 below the freeze-dried preparation of the solid essence 2. The moisture absorption mechanism includes a cylindrical seat body 4 which is coaxially arranged with the sleeve 1 and can slide back and forth in the barrel cavity of the sleeve 1 (below the limiting structure 13) along the axial direction of the sleeve 1. A hole 41 connecting the horizontal upper and lower surfaces of the seat body 4 is coaxially opened on the seat body 4. An extension tube 43 which is coaxially arranged and connected with the hole 41 extends vertically upward from the upper surface of the seat body 4. At the same time, a circle of baffles 44 extends vertically upward from the upper surface of the seat body 4. The area surrounded by the baffles 44 cooperates with the extension tube 43 to form an annular groove 45 which opens upward and is coaxially arranged with the extension tube 43, as shown in the attached Figure 1 , 2 As shown,

[0045] A sponge body as a moisture absorption head 3 is coaxially arranged on the upper surface of the seat body 4. The sponge body is designed as a sleeve with an opening facing vertically downward. The sponge body is coaxially fitted into the annular groove 45 and fully covers the top pipe opening of the extension tube 43. The sleeve section at the lower part of the sleeve-shaped sponge body is fully squeezed into the groove cavity of the annular groove 45 and forms an obvious interference fit with the groove cavity of the annular groove 45 through its own elastic expansion, so that the sponge body is not easy to fall off when installed on the seat body 4. After the sponge body coaxially enters the sleeve 1 cavity, the head part of its upper part will be appropriately squeezed inward in the horizontal annular direction by the sleeve 1 cavity wall, such as the attached Figure 1 As shown;

[0046] On the annular barrel cavity wall below the solid essence 2 freeze-dried preparation in the sleeve 1, there is a frosted section 12 along the axial direction of the sleeve 1. The relative friction between the seat body 4 and the frosted section 12 is greater than the relative friction between the seat body 4 and other areas of the barrel cavity wall of the sleeve 1 except the frosted section 12. After assembly and before use, the seat body 4 is located below the frosted section 12 or is stuck in the frosted section 12 without moving, thereby preventing the seat body 4 from moving up in the barrel cavity of the sleeve 1 until the dry sponge of the moisture absorption head 3 pushes upward to the freeze-dried preparation;

[0047] On the basis of the above structure, a liquid feeding device is connected to the bottom of the sleeve 1. Figure 6 As shown, the liquid feeding device is an extrusion type liquid feeding device, including a mounting tube 5 with a vertical axis, a connecting tube 51 for connecting the channel 41 and the mounting tube 5 cavity extending vertically upward from the top of the mounting tube 5, and the sleeve 1 is coaxially matched downward through the seat body 4 to cover the top opening of the connecting tube 51. In a natural state, the sleeve 1 is prevented from sliding relative to the seat body 4 to the solid essence 2 on the upper part of the sleeve 1 and being pushed by the moisture absorption head 3 by the locking mechanism.

[0048] (The bottom of the channel 41 is expanded, and the expansion is matched with the top of the connecting tube 51. At the same time, referring to the clamping mechanism in Example 2, a third clamping ring is coaxially arranged with the seat body 4 by horizontally annularly protruding inwardly on the annular inner cavity wall of the expansion, and a fourth clamping ring is coaxially arranged with the connecting tube 51 by correspondingly horizontally annularly protruding outwardly on the tube body of the connecting tube 51 near the top. The inner ring diameter of the third clamping ring is slightly smaller than the outer ring diameter of the fourth clamping ring. In the natural state, the third clamping ring blocks the fourth clamping ring from passing therethrough, and the blocking force of the third clamping ring on the fourth clamping ring is smaller than the blocking force of the aforementioned clamping mechanism on the seat body 4. The third and fourth clamping rings are not drawn in the figure)

[0049] The liquid feeding device also includes a liquid storage cylinder 6, which is coaxially inserted into the mounting cylinder 5 and can slide back and forth in the cylinder cavity of the mounting cylinder 5.

[0050] A discharge pump mechanism is fixedly installed on the top of the liquid storage cylinder 6. The discharge pump mechanism includes a cover plate 61 which is screwed tightly to the top pipe opening of the liquid storage cylinder 6 and is coaxially arranged with the liquid storage cylinder 6. A transfer cavity 62 coaxially arranged with the liquid storage cylinder 6 is fixedly connected to the center of the horizontal lower plate surface of the cover plate 61. The transfer cavity 62 is equivalent to extending vertically downward from the cover plate 61 into the tube cavity of the liquid storage cylinder 6.

[0051] A one-way valve 621 is installed at the bottom of the transfer chamber 62 for realizing one-way communication between the transfer chamber 62 and the cylinder cavity of the liquid storage cylinder 6. A first piston 7 that can slide back and forth in the transfer chamber 62 is coaxially embedded in the transfer chamber 62. A discharge pipe 8 with a vertical axis can be coaxially penetrated on the first piston 7 to slide back and forth. The discharge pipe 8 passes through the cover plate 61 vertically upward along its own length direction and abuts against the top of the cylinder cavity of the installation cylinder 5 to be connected with the bottom end opening of the connecting pipe 51, and the discharge pipe 8 can slide back and forth on the cover plate 61.

[0052] The bottom end of the discharge pipe 8 is sealed, and a discharge port 81 is provided on the body of the discharge pipe 8, which is connected to the discharge pipe 8 cavity and the transfer cavity 62, and the axial direction is horizontal. The discharge port 81 is blocked by the annular surface of the first piston 7 ring cavity tightly sleeved on the discharge pipe 8. The tube body at the bottom end of the discharge pipe 8 horizontally protrudes outward in an annular direction to form a circle for preventing the first piston 7 from downwardly escaping from the discharge pipe 8. The limiting portion 83,

[0053] The tube body at the top of the discharge tube 8 extends outward in a horizontal annular direction to form a circle of support plates 82 with a horizontal plate surface. A spring 9 with a vertical axial direction is provided between the support plate 82 and the cover plate 61 as an elastic support. The spring 9 is coaxially sleeved on the tube section of the discharge tube 8 between the support plate 82 and the cover plate 61.

[0054] A second piston 10 is embedded near the bottom of the liquid storage cylinder 6 and can coaxially reciprocate and slide in the liquid storage cylinder 6. An air cavity is formed between the second piston 10 and the bottom of the liquid storage cylinder 6. A vent 63 connecting the air cavity and the external atmosphere is opened at the bottom of the liquid storage cylinder 6.

[0055] Before use, add solvent water for dissolving the freeze-dried preparation into the liquid storage cylinder 6 and the transfer chamber 62, such as the attached Figure 6 As shown: first, the sleeve 1 is coaxially downwardly matched through the seat body 4 to cover the top opening of the connecting tube 51, and the fourth clamping ring is pressed down to make it pass vertically upward through the ring cavity of the third clamping ring by hard friction, while the connecting tube 51 is almost pushed upward to the horizontal step surface of the expanded opening of the channel 41, thereby achieving basic clamping between the seat body 4 and the connecting tube 51 (the blocking force of the third clamping ring on the fourth clamping ring is smaller than the blocking force of the aforementioned clamping mechanism on the seat body 4). In this way, during the subsequent water discharge and use process, the sleeve 1 and the moisture absorption mechanism are not easy to detach or fall off from the installation tube 5.

[0056] At this time, since the sleeve 1 is no longer subjected to any downward pressure except its own gravity, the locking mechanism of this embodiment can prevent the sleeve 1 from sliding relative to the base 4 to the upper part of the sleeve 1 and the lyophilized preparation dried by the hygroscopic head 3, thereby preventing the lyophilized preparation from being broken and ejected from the sleeve 1 in a dry state before use;

[0057] As attached Figure 7 , and then keep the installation cylinder 5 stationary, and push the liquid storage cylinder 6 upward in the installation cylinder 5. Since the discharge pipe 8 is vertically upward against the top of the cylinder cavity of the installation cylinder 5, the discharge pipe 8 is stationary, and the liquid storage cylinder 6 and the cover plate 61 move upward relative to the discharge pipe 8, so that the space area between the first piston 7 and the bottom of the transfer chamber 62 (hereinafter referred to as the "water storage area") is compressed and reduced (at the same time, the spring 9 is compressed), forcing the water in the water storage area to push the first piston 7 vertically upward, so that the first piston 7 is slightly vertically upward on the discharge pipe 8. The discharge port 81 is exposed by sliding, so that the water in the water storage area is pressed upward to the upper part of the sponge body as the moisture absorption head 3 through the discharge port 81 and successively through the discharge pipe 8, the connecting pipe 51, the channel 41, and the extension pipe 43, so that the sponge body absorbs water and gets wet quickly (before use, the air in the water storage area is first discharged through the above operation, and the water is simultaneously brought up to the water storage area). The above pushing operation can be repeated to make the upper part of the sponge body fully wet. During this process, the one-way valve 621 is always in a closed state under the water pressure in the transfer chamber 62.

[0058] During the process of pushing out water, after the liquid storage cylinder 6 is released (keeping the mounting cylinder 5 stationary), the spring 9 rebounds and restores to push the liquid storage cylinder 6 and the cover plate 61 downward. Because the friction between the first piston 7 and the discharge pipe 8 is greater than the friction between the first piston 7 and the side wall of the transfer chamber 62, the water storage area space between the first piston 7 and the bottom of the transfer chamber 62 is expanded again; at the same time, since the discharge pipe 8 will also have a small degree of relative displacement with the first piston 7, the discharge port 81 on the discharge pipe 8 is blocked by the first piston 7 again. When the discharge port 81 is blocked, the space of the water storage area is expanded, which causes a pressure difference between the water storage area and the outside world. Under the action of the atmospheric pressure of the outside world, the atmospheric pressure enters the air cavity between the second piston 10 and the bottom of the liquid storage cylinder 6 through the vent hole 63 at the bottom of the liquid storage cylinder 6, and pushes the second piston 10 to slide upward in the tube cavity of the liquid storage cylinder 6, pushing the water in the liquid storage cylinder 6 upward and opening the one-way valve 621 to complete the water filling into the transfer cavity 62 for the next use (when the water in the liquid storage cylinder 6 is almost used up, the cover plate 61 can be unscrewed to add water to the liquid storage cylinder 6);

[0059] After the sponge is fully moistened, the sleeve 1 is pinched and pressed down vertically. The reaction force of the connecting tube 51 on the seat 4 causes the seat 4 to overcome the friction between it and the frosting section 12 and then slide upward in the sleeve 1. Due to the porous nature of the freeze-dried preparation, which is easy to disintegrate when exposed to water, during the process of the seat 4 supporting the sponge to move upward, the part of the freeze-dried preparation that contacts the wet sponge will quickly disintegrate and dissolve and attach to the sponge. Figure 8 Therefore, after the sponge body moves upward and finally extends out of the sleeve 1 (the sponge body shrinks and expands through its own elasticity, and squeezes upward through the top opening of the sleeve 1, the sponge body recovers its shape, and is stuck on the top of the sleeve 1 without falling off, as shown in the attached Fig. 9 ), the entire freeze-dried preparation is also melted and relatively concentrated in the porous structure of the upper part of the sponge.

[0060] In the above paragraph, the action of pushing the sponge upward from the sleeve 1 is done in one go without pause (this is also in line with the actual use operation). The process is very short, during which the sponge must also break through the freeze-dried preparation blocking the top opening of the sleeve 1. It should be noted that the freeze-dried preparation is located at the outlet of the sleeve 1. According to common sense, such a short process will cause some or even a considerable portion of the solid preparation that has not had time to dissolve to be crushed and scattered around, or even the solid preparation to be pushed out and dropped in large pieces, affecting the utilization rate of the preparation and causing losses. However, this phenomenon did not occur in reality, which is largely based on the characteristics of freeze-dried preparations: freeze-dried preparations are rich in a large number of microporous structures, have a strong tendency to absorb water and are easy to deliquesce, which results in that when the moist sponge is against the freeze-dried preparation, the water on the sponge can quickly diffuse and moisten the entire freeze-dried preparation, causing the freeze-dried preparation to quickly soften and melt as a whole. In this way, the upward push of the sponge can enable the softened freeze-dried preparation to smoothly adhere to the sponge as a whole, and further dissolve during the upward movement of the sponge; other solid preparations do not have such a fast water absorption and diffusion effect, resulting in a large part of the solid preparation not having time to moisten and soften when being pushed, and being broken and lifted up by the pushing action.

[0061] It can be seen that the present application is a dynamic dissolution scheme designed with full consideration of the characteristics of freeze-dried preparations (for the effect of the dynamic dissolution, a detailed simulation observation experiment is recorded below). Compared with the traditional habit of leaving the solid essence to dissolve and then applying it, the device of the present application is more convenient and quicker to use.

[0062] After that, hold the mounting tube 5 and apply it to the skin through the sponge, so that the essence of the freeze-dried preparation is transferred and applied to the skin; and during the application process, the sponge can continue to be hydrated through the above-mentioned pushing operation to promote the dissolution of the essence and promote the essence on the sponge to be better squeezed onto the skin, thereby improving the utilization rate of the essence (the limiting structure at the top opening of the sleeve 1 is used to prevent the moisture absorption mechanism from detaching).

[0063] The aforementioned through hole 21 is provided on the freeze-dried preparation to achieve ventilation more smoothly, so that the operation of injecting water into the sponge and pushing the moisture absorption mechanism upward can be smoother.

[0064] After the coating is completed, the sleeve 1 and the moisture absorption mechanism are pulled upwards away from the connecting tube 51 and discarded or recycled; when used next time, a new sleeve 1 equipped with the freeze-dried preparation and the moisture absorption mechanism is replaced, and the above operation is repeated; of course, several sleeves 1 equipped with the freeze-dried preparation and the moisture absorption mechanism can also be used in one coating process, which is entirely determined by the required dosage;

[0065] Another advantage of selecting a sponge as the moisture absorbing head 3 is that the sponge as an elastic material is appropriately squeezed inwardly in the horizontal annular direction by the wall of the sleeve 1 in the sleeve 1. Figure 1, 3 In this way, the sponge can also bring out the freeze-dried preparation remaining on the inner wall of the sleeve 1 during the rising process in the sleeve 1, thereby improving the discharge rate of the essence from the sleeve 1.

[0066] Simulation experiment 1

[0067] A sleeve 1 of the present invention having an inner diameter of 12 mm and an axial length of 30 mm is selected. Referring to the freeze-drying assembly process described in Example 1, the sleeve 1 is inverted and inserted into the positioning groove cavity in an inverted manner. A filling needle having an outer diameter of 4 mm and a vertical length direction is coaxially inserted vertically downward into the sleeve cavity of the sleeve 1 and close to the bottom of the positioning groove cavity. The position is maintained. The aqueous pre-preparation liquid of the freeze-dried preparation composed of 30 parts of resveratrol, 20 parts of glycerol, 5 parts of squalane, 1 part of chitosan, 3 parts of PVP, and 100 parts of water is filled into the sleeve cavity of the sleeve 1 to a height of 5 mm through the filling needle. After sufficient freeze-drying, the filling device is moved upward to pull out the filling needle, and then the sleeve 1 is taken out from the positioning groove and turned over to reset, so as to obtain a quasi-cylindrical freeze-dried preparation having a radial dimension of 12 mm, a height of 5 mm, and an axial through hole 21 with a diameter of 4 mm, which is coaxially filled and fixed at the top opening of the cavity;

[0068] The sponge body is a sleeve-shaped cap structure with an opening facing vertically downward, which is formed by a hemispherical body at the top and a cylindrical body at the bottom coaxially. The radius of the hemispherical body is 7mm, the thickness of the cylindrical body wall is 5mm, and the axial height is 5mm. Fig.10 ,

[0069] The seat body 4 matched with the above-mentioned sponge body is an axially vertical cylinder, and its radial dimension is slightly smaller than the sleeve 1 barrel cavity, so that it can slide back and forth in the sleeve 1 barrel cavity. A hole 41 connecting the horizontal upper and lower surfaces of the seat body 4 is coaxially opened on the seat body 4. An extension tube 43 coaxially arranged and connected with the hole 41 extends vertically upward on the upper surface of the seat body 4. The axial height of the extension tube 43 relative to the upper surface of the seat body 4 is 5mm, and the outer diameter is 4mm. At the same time, a circle of circumferentially extending upward on the upper surface of the seat body 4 The baffle 44, the area surrounded by the baffle 44 cooperates with the extension tube 43 to form an annular groove 45 with an opening facing upward and coaxially arranged with the extension tube 43, wherein the axial height of the baffle 44 relative to the upper surface of the seat body 4 is 3.5mm, and the groove width of the annular groove 45 is 2mm. After the sponge is elastically squeezed by the wall of the cylindrical barrel at the lower part, it is coaxially embedded in the annular groove 45 downward and just covers the extension tube 43 downward (the top end of the extension tube 43 basically presses on the lower plane of the hemisphere upward), as shown in the attached Fig.11 ,

[0070] Will attach Fig.11The seat body 4 is coaxially fitted upward into the sleeve 1 cavity of this experiment and the sponge body is inserted into the sleeve 1 cavity as a whole (in order to simulate the needs of the experiment, no clamping mechanism is temporarily provided on the inner cavity wall of the sleeve 1), and the joint of the seat body 4 and the sleeve 1 is pinched so that the seat body 4 and the sleeve 1 basically do not move relative to each other (as shown in the attached Fig.12 ), in this state, squeeze 0.5mL of water upward into the sponge through the hole 41, and blow air upward into the hole 41 through the ear cleaning bulb, so as to blow the water attached to the inner wall of the hole 41 and the inner wall of the extension tube 43 into the sponge as much as possible (to improve the accuracy of the water application), and then put the seat body 4 axially and vertically downward on the support column 14. At this time, loosen the seat body 4 and make the bottom edge of the sleeve 1 basically flush with the upper surface of the seat body 4, loosen the sleeve 1 (such as attached Fig.13 ) The sleeve 1 is put on the seat 1 and the wet sponge in a motion close to free fall and falls naturally. During the free fall, the support column 14 and the seat 4 remain in place. Finally, under the reaction force of the support column 14, the freeze-dried preparation at the top opening of the sleeve 1 is pushed out of the sleeve 1. After being pushed out, the freeze-dried preparation melts and attaches to the head of the sponge. No freeze-dried preparation debris is observed to be knocked out.

[0071] In the above experiment, since the cylindrical barrel on the sponge of the sleeve-like cap structure is elastically compressed to a large extent in the annular groove 45, it is assumed that the injected 0.5 mL of water is completely diffused on the hemispherical body on the upper part of the sponge (the volume of the hemispherical body is 7×7×7×π×4÷3÷2=718 cubic millimeters), that is, the amount of water applied on the unit sponge is 500 cubic millimeters / 718 cubic millimeters, 500 / 718 (considering that part of the water will also diffuse to the cylindrical barrel located in the annular groove 45 on the sponge, the actual amount of water on the hemispherical sponge is less than this value).

[0072] According to the free fall motion calculation, when the sleeve 1 falls to the moment when the freeze-dried preparation at the top opening of the sleeve 1 just touches the sponge on the seat 4, the falling speed v of the sleeve 1 at this time is approximately (assuming that after the sleeve 1 is inserted into the barrel cavity of the sleeve 1, the radius of the upper hemisphere of the sponge is maintained at 7 mm, the same below): v 2 =2×9.8×0.013, v=0.5m / s.

[0073] Simulation experiment 2

[0074] The sleeve 1 of the present invention with an axial length of 45 mm was replaced, and the other parameters and operations were the same as those of the simulation experiment 1:

[0075] After the sleeve 1 freely falls, the freeze-dried preparation at the top opening of the sleeve 1 is pushed out of the sleeve 1 by the sponge. After being pushed out, the freeze-dried preparation melts over a large area and attaches to the head of the sponge. No freeze-dried preparation debris is observed to be knocked out.

[0076] According to the free fall motion calculation, when the sleeve 1 falls to the moment when the freeze-dried preparation at the top opening just touches the sponge on the seat 4, the falling speed v of the sleeve 1 at this time is approximately: v 2 =2×9.8×0.028, v=0.74m / s.

[0077] Simulation experiment 3

[0078] The sleeve 1 of the present invention with an axial length of 60 mm was replaced, and the other parameters and operations were the same as those of the simulation experiment 1:

[0079] After the sleeve 1 freely falls, the freeze-dried preparation at the top opening of the sleeve 1 is pushed out of the sleeve 1 by the sponge. After being pushed out, the freeze-dried preparation softens as a whole and attaches to the head of the sponge and continues to dissolve. No freeze-dried preparation debris is observed to be knocked out.

[0080] According to the free fall motion calculation, when the sleeve 1 falls to the moment when the freeze-dried preparation at the top opening just touches the sponge on the seat 4, the falling speed v of the sleeve 1 at this time is approximately: v 2 =2×9.8×0.043, v=0.92m / s.

[0081] It can be seen from the above simulation experiment that when the falling speed of the sleeve 1, that is, the speed of ejecting the freeze-dried preparation upward is 0.5-0.92 m / s, or when the ejection speed is at least below 0.92 m / s, the phenomenon of "part of the freeze-dried preparation is not attached to the sponge but is scattered around the sleeve 1" does not occur; combined with the description of the use process of Example 1, when the hand pinches the sleeve 1 and naturally presses it vertically downward, the control speed of the hand on the sleeve 1 is also within the above speed range. Therefore, in actual use, it is sufficient to pinch the sleeve 1 and press it naturally, and there is no need to deliberately control the pressing speed, so it is very convenient.

[0082] Example 2

[0083] As attached Figure 3 , 4 As shown in Figures 5, compared with Example 1, Example 2 does not specifically set the frosted section 12 on the inner cavity wall of the sleeve 1, but a first clamping ring 11 is formed on the inner cavity wall of the sleeve 1 below the freeze-dried preparation and is horizontally annularly protruded inwardly to form a first clamping ring 11 coaxially arranged with the sleeve 1, and a second clamping ring 42 is correspondingly protruded outwardly horizontally on the seat body 1 to form a second clamping ring 42 coaxially arranged with the seat body 4. The inner ring diameter of the first clamping ring 11 is slightly smaller than the outer ring diameter of the second clamping ring 42. In the natural state, the first clamping ring 11 blocks the second clamping ring 42 from passing therethrough. The blocking force of the first clamping ring 11 on the second clamping ring 42 is greater than the blocking force of the third clamping ring on the fourth clamping ring. The rest of the design is the same as Example 1.

[0084] Therefore, the operation is different from that of Example 1: after the sponge is fully moistened by injecting water, the sleeve 1 is pinched and pressed vertically downward, and the reaction force of the connecting tube 51 on the seat body 4 causes the second clamping ring 42 to be squeezed vertically upward from the annular cavity of the first clamping ring 11 by hard friction, so that the moisture absorption mechanism can contact upward to melt and dissolve the freeze-dried preparation.
