Description

Technical Field

[0001] The present invention relates to the technical field of medicine spraying, and particularly to a medicine spraying device for relieving fatigue in rehabilitation exercises. Background Art

[0002] In the field of rehabilitation exercises, local fatigue relief is a key link in improving training effects and preventing sports injuries. Medicine spraying devices have become common tools in sports rehabilitation by precisely applying liquid medicines with muscle-soothing, blood circulation-promoting, or anti-inflammatory effects in the form of a mist to the target area. However, in the prior art, medicine spraying devices (such as traditional spray bottles) usually adopt a one-way flow channel design, and by pressing the top, the liquid in the bottle is transported along a fixed pipeline to the nozzle and atomized for spraying. However, such devices have the following technical defects in practical applications: After each use, a certain amount of medicine inevitably remains inside the pipeline. More seriously, since the end of the pipeline is directly exposed to the external environment, these residual medicines are extremely likely to come into contact with oxygen, microorganisms, and various pollutants in the air. Such contact often triggers a series of physical or chemical changes, such as oxidation reactions, precipitation formation, volatilization losses, etc. These changes not only cause the gradual degradation of the active ingredients in the medicine but also may result in the contamination of the medicine, thus seriously affecting its use effect.

[0003] It should be particularly noted that this problem is particularly prominent in medicines that require long-term storage or have high requirements for stability. For example, rehabilitation medicines containing bioactive ingredients, due to the particularity and sensitivity of their ingredients, once degradation or contamination occurs, their efficacy will be greatly weakened, and even adverse consequences may occur.

[0016] 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 creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 - 12 , the present invention provides a technical solution: a medicament spraying device for relieving fatigue in rehabilitation exercises, including a bottle body 1 and a sealing cover 2 installed at the bottle mouth of the bottle body 1. A transfer bin 3 is arranged inside the sealing cover 2, and a pressing cap 4 is elastically slidably arranged inside the sealing cover 2; Further included are: An inner valve core 31 and an outer valve core 32, both slidably arranged inside the transfer bin 3, and the inner valve core 31 and the outer valve core 32 can be mutually attached to form a sealing surface for controlling the communication state between the transfer bin 3 and the bottle body 1; An elastic member 33, installed between the inner valve core 31 and the outer valve core 32, for providing a restoring force; A commutator 5, installed inside the transfer bin 3, for switching the axial movement states of the inner valve core 31 and the outer valve core 32 to realize the switching of the liquid medicine flow direction; The compression part 6 can move up and down and rotate with the pressing cap 4; the bottom of the compression part 6 is communicated with the transfer bin 3 and is slidably sealed with the inner wall of the transfer bin 3 through a sealing member (including but not limited to an O-ring). In the spraying state, the inner valve core 31 can slide along the axis of the transfer bin 3, and the outer valve core 32 is fixed relative to the transfer bin 3; when the compression part 6 moves up and down, it can change the volume of the transfer bin 3 to realize liquid suction and drainage. When the compression part 6 rotates, the axial movement states of the inner valve core 31 and the outer valve core 32 are switched through the commutator 5; the outer valve core 32 can slide along the axis of the transfer bin 3, and the inner valve core 31 is fixed relative to the transfer bin 3; the switching of the liquid flow direction is realized. The horizontal groove 61 is horizontally communicated with the opening side of the compression part 6 and the pressing cap 4. The vertical groove 62 is communicated with the horizontal groove 61 and the inner cavity of the compression part 6 at both ends respectively. The upper switching part 63 and the lower switching part 64 are both elastically slidably arranged in the compression part 6, and upper grooves 65 capable of selectively communicating with the horizontal groove 61 and lower grooves 66 capable of selectively communicating with the vertical groove 62 are respectively arranged on the side walls. Spraying state: During the liquid spraying process, refer to Figure 3 and Figure 4 , by pressing down on the pressing cap 4, the pressing cap 4 descends relative to the sealing cover 2, and then pushes the compression part 6 to move and compresses the internal space of the transfer bin 3; at this time, the outer valve core 32 remains axially fixed relative to the transfer bin 3, and the inner valve core 31 cannot move axially along the transfer bin 3 due to the restriction of the outer valve core 32; as the internal space of the transfer bin 3 decreases, the internal pressure of the transfer bin 3 gradually increases; when the internal pressure of the transfer bin 3 overcomes the elastic force applied to the upper switching part 63 (in this embodiment, the elastic forces applied to the upper switching part 63 and the lower switching part 64 are both applied by the spring installed on the compression part 6), the upper switching part 63 rises relative to the compression part 6 under the action of the pressure, and the upper groove 65 gradually approaches the horizontal groove 61; when the upper groove 65 is communicated with the horizontal groove 61, the liquid in the transfer bin 3 under the action of the pressure passes through the compression part 6, the upper groove 65 and the horizontal groove 61 in sequence, and finally passes through the pressing cap 4 and is sprayed out. During the liquid aspiration process, the push cap 4 is released and, under the action of the spring, moves upward relative to the sealing cover 2 (i.e., the reset process), causing the compression portion 6 to rise. Simultaneously, the upper switching member 63 is reset under the action of the spring, causing the upper groove 65 to be offset from the transverse groove 61, thereby cutting off the connectivity between the compression portion 6 and the push cap 4. At this point, the interior of the transfer chamber 3 is sealed. As the compression portion 6 further rises, the internal space of the transfer chamber 3 is stretched, and the pressure inside the transfer chamber 3 decreases. Under the action of the pressure difference, the inner valve core 31 moves upward relative to the outer valve core 32 (the force applied by the elastic member 33 to the inner valve core 31 is less than the force applied by the spring to the lower switching member 64. The setting of this elastic force is a conventional method and is omitted here in detail), thereby creating a gap between the inner valve core 31 and the outer valve core 32. Liquid is aspirated into the transfer chamber 3 under the action of the pressure difference between the transfer chamber 3 and the bottle body 1. The transfer chamber 3 is then filled with liquid in a free state, waiting for the next downward pressure on the push cap 4.

[0018] The process of switching the flow direction of the liquid medicine: the pressing cap 4 is rotated, which drives the compression part 6 to rotate, and switches the movement state of the inner valve core 31 and the outer valve core 32 through the reversing device 5, so that the outer valve core 32 axially fixed to the transfer chamber 3 is switched to the inner valve core 31. During this process, the outer valve core 32 originally axially fixed to the transfer chamber 3 is switched to the inner valve core 31, that is, the inner valve core 31 now remains axially fixed relative to the transfer chamber 3, and the outer valve core 32 can move axially relative to the transfer chamber 3; Liquid return status: Liquid reflux process: when pressure is applied to the pressing cap 4 again, the pressing cap 4 moves axially downward relative to the sealing cover 2, and the compression part 6 moves accordingly and compresses the internal space of the transfer chamber 3. At this time, the inner valve core 31 remains axially fixed relative to the transfer chamber 3, while the outer valve core 32 is able to move; as the internal pressure of the transfer chamber 3 increases, the outer valve core 32 moves relative to the transfer chamber 3 and descends axially along the transfer chamber 3 (the force applied to the outer valve core 32 is less than the force applied to the upper switching member 63); the outer valve core 32 stretches the elastic member 33 and forms a gap with the inner valve core 31, and the transfer chamber 3 is connected to the interior of the bottle body 1. As the compression part 6 continues to compress the internal space of the transfer chamber 3, the liquid at the bottom of the transfer chamber 3 flows back into the bottle body 1 through the gap between the outer valve core 32 and the inner valve core 31, completing a single liquid return stroke; After the pressing cap 4 is released, the pressing cap 4 rises relative to the sealing cover 2 under the action of the elastic force, and the compression part 6 rises axially along the transfer chamber 3; the top of the compression part 6 is no longer connected to the pressing cap 4, and the outer valve core 32 is reset under the pulling force of the elastic member 33, and the outer valve core 32 contacts the inner valve core 31, so that the bottle body 1 and the transfer chamber 3 are disconnected; as the compression part 6 continues to rise, the internal space of the transfer chamber 3 is stretched, and the pressure inside the transfer chamber 3 is reduced; the outer valve core 32 is restricted by the inner valve core 31 and cannot continue to rise, see Figure 3, the compression part 6 is connected to the transfer bin 3, and the pressure inside the compression part 6 also decreases accordingly; when the pressure inside the transfer bin 3 and the compression part 6 overcomes the force applied to the lower switching part 64, the lower switching part 64 descends along the axis of the compression part 6, and the lower groove 66 gradually approaches the inner opening of the vertical groove 62. When the lower groove 66 communicates with the inner opening of the vertical groove 62, the outside air enters the compression part 6 through the pressing cap 4, the horizontal groove 61, the vertical groove 62 and the lower groove 66, and finally enters the transfer bin 3 through the compression part 6 to make up for the space of the liquid reflux part in the transfer bin 3; Repeat the operation, and the liquid in the transfer bin 3 can be completely refluxed into the bottle body 1; the upper switching part 63 and the lower switching part 64 at the inner top of the compression part 6 block the inner ends of the horizontal groove 61 and the vertical groove 62, disconnecting the top of the compression part 6, realizing the first partition; and the inner valve core 31 and the outer valve core 32 perform a secondary partition between the transfer bin 3 and the bottle body 1. The double partition maximally ensures that the physical and chemical forms of the liquid in the bottle body 1 are not affected by external factors, greatly guarantees the liquid drug properties, extends the storage time of the liquid medicine, and can also prevent the liquid from solidifying inside the transfer bin 3, resulting in the blockage of the transfer bin 3 and affecting the next use.

[0019] As a further solution of the present invention, the commutator 5 includes; A synchronizing member 51, rotatably arranged in the transfer bin 3, and capable of rotating synchronously with the compression part 6; An upper limiting groove 52 and a lower limiting groove 53, both opened on the side wall of the synchronizing member 51, both having an L-shaped structure, and the vertical ends of the upper limiting groove 52 and the lower limiting groove 53 are arranged in a staggered manner, for switching the movement states of the inner valve core 31 and the outer valve core 32 along the axis of the transfer bin 3; Sliders 54, arranged in pairs and both axially slidably connected to the transfer bin 3 through grooves. The outer valve core 32 and the inner valve core 31 are respectively fixed through the corresponding sliders 54, and are slidably arranged by embedding the corresponding sliders 54 into the upper limiting groove 52 and the lower limiting groove 53; the slider 54 includes an upper slider 54-1 fixed to the inner valve core 31 and a lower slider 54-2 fixed to the outer valve core 32; The synchronizing member 51 and the transfer bin 3 adopt a detachable design. The specific connection method includes but is not limited to: screwing a ring plate on the top of the transfer bin 3, and the ring plate contacts the upper surface of the synchronizing member 51, so as to realize the detachability of the synchronizing member 51 and the transfer bin 3, and allow the synchronizing member 51 to rotate around the axis of the transfer bin 3; a plurality of connecting plates 51-1 are arranged on the synchronizing member 51, and the upper limiting groove 52 and the lower limiting groove 53 are respectively arranged on different connecting plates 51-1; the connecting plates 51-1 are in interference fit with the synchronizing member 51. The purpose is that when the upper limiting groove 52 and the lower limiting groove 53 affect the tight fit of the inner valve core 31 and the outer valve core 32 due to wear, by replacing the connecting plates 51-1, the replacement of the upper limiting groove 52 and the lower limiting groove 53 can be realized, thereby improving the sealing performance of the inner valve core 31 and the outer valve core 32.

[0020] Specifically, refer to Figure 3 、 Figure 5 、 Figure 8 and Figure 9 When the injection state is switched to the liquid return state, by rotating the pressing cap 4, the compression part 6 rotates, the synchronizing part 51 rotates accordingly, and drives the upper limit groove 52 and the lower limit groove 53 to rotate through the connecting plate 51-1, so that the upper limit groove 52 changes from contacting the upper slider 54-1 at the intersection of the vertical section and the horizontal section to contacting the horizontal section of the upper limit groove 52, realizing that the inner valve core 31 can axially move along the transfer chamber 3 and is switched to being axially fixed to the transfer chamber 3; at the same time, the lower limit groove 53 changes from the horizontal section moving to contact the lower slider 54-2 to the intersection of the vertical section and the horizontal section of the lower limit groove 53 contacting it, realizing that the outer valve core 32 is switched from being axially fixed relative to the transfer chamber 3 to being able to axially move along the transfer chamber 3; conversely, the inner valve core 31 can axially move along the transfer chamber 3 is restored, and the outer valve core 32 is axially fixed relative to the transfer chamber 3, realizing the switching of the liquid flow direction by rotating the pressing cap 4, facilitating the return of the liquid medicine inside the transfer chamber 3 to the bottle body 1, prolonging the storage time and efficacy of the liquid medicine, and being convenient to operate; As a further solution of the present invention, elastic plates 55 and stop blocks 56 are fixedly provided on both the upper limit groove 52 and the lower limit groove 53. The elastic plates 55 and the stop blocks 56 are respectively arranged on the upper and lower sides in the middle of the horizontal ends of the upper limit groove 52 and the lower limit groove 53, and the elastic plate 55 distributed along the axis of the transfer chamber 3 is located inside the stop block 56; Specifically, refer to Figure 9 There is partial overlap along the axis of the transfer chamber 3 between the horizontal sections of the upper limit groove 52 and the lower limit groove 53. When the slider 54 moves to the overlapping part of the horizontal sections of the upper limit groove 52 and the lower limit groove 53, both the inner valve core 31 and the outer valve core 32 are axially fixed relative to the transfer chamber 3; at this time, pressing down the pressing cap 4 can prevent the upper limit groove 52 or the lower limit groove 53 from moving, resulting in the connection between the transfer chamber 3 and the bottle body 1, thereby effectively avoiding the liquid medicine in the idle injection device from being ejected due to accidentally touching the pressing cap 4, causing waste of the liquid medicine; At the same time, when the slider 54 moves to the stop block 56, the upper slider 54-1 and the lower slider 54-2 can approach each other and the elastic plate 55, making the inner valve core 31 and the outer valve core 32 approach each other, enhancing the extrusion degree between the inner valve core 31 and the outer valve core 32. When used for long-term storage of the liquid medicine, the sealing effect at the inner valve core 31 and the outer valve core 32 can be enhanced.

[0021] As a further solution of the present invention, a chute 21 is provided inside the sealing cap 2. A reset ring 22 is slidably arranged in the chute 21. A reset spring 23 is fixedly arranged between the reset ring 22 and the sealing cap 2. A limiting ring 24 slidably arranged in the chute 21 is fixedly arranged at the bottom of the pressing cap 4. Fillets are arranged on the side wall of the limiting ring 24 and the top side wall of the chute 21; the fillets can facilitate the deformation of the limiting ring 24 under the action of the top side wall of the chute 21, so as to facilitate the installation and disassembly of the pressing cap 4; Specifically, refer to Figure 2 , Figure 10 and Figure 11 . When installing the pressing cap 4, the limiting ring 24 at the bottom of the pressing cap 4 is squeezed into the chute 21. The limiting ring 24 is slightly deformed to reduce the outer diameter of the limiting ring 24, so as to facilitate the entry of the limiting ring 24 into the chute 21; when pressing down the pressing cap 4, the bottom of the pressing cap 4 presses down the reset ring 22, and the reset ring 22 compresses the reset spring 23, and the reset spring 23 stores energy. After releasing the pressing cap 4, the reset spring 23 reversely resets the pressing cap 4, so as to realize the elastic sliding of the pressing cap 4 relative to the sealing cap 2.

[0022] As a further solution of the present invention, the upper switching member 63 is slidably and sealingly arranged on the inner wall of the compression part 6. Both the upper and lower ends of the lower switching member 64 are slidably and sealingly arranged on the compression part 6, and limiting parts 67 are arranged at both ends of the lower switching member 64. A fixing part 68 is fixedly arranged on the inner wall of the compression part 6. The fixing part 68 is used for limiting the limiting parts 67; Specifically, refer to Figure 7 . The fixing part 68 can limit the axial movement of the lower switching member 64 along the compression part 6, which can prevent the upper groove 65 from communicating with the inner side end of the vertical groove 62, resulting in a reduction in the liquid absorption effect; it can also prevent the lower groove 66 from communicating with the inner side end of the horizontal groove 61, resulting in a reduction in the liquid return effect.

[0023] As a further solution of the present invention, grooves 71 are provided on the inner side of the pressing cap 4 and the bottom of the synchronizing member 51. Guide rails 72 are fixedly arranged on the top of the compression part 6 and the inner wall of the transfer bin 3; the compression part 6 rotates synchronously with the pressing cap 4 through the guide rails 72 and the grooves 71, and the compression part 6 drives the synchronizing member 51 to rotate through the guide rails 72 and the grooves 71; Specifically, the pressing cap 4 cooperates with the guide rail 72 on the outer side of the synchronous compression part 6 through the groove 71 on the inner side, so as to realize that the pressing cap 4 can drive the compression part 6 to rotate while the compression part 6 can move axially along the sealing cap 2 with the pressing cap 4; the compression part 6 cooperates with the guide rail 72 on the inner side of the synchronizing member 51 through the groove 71 at the bottom, so as to realize that the compression part 6 can slide axially along the transfer bin 3 with the synchronizing member 51 and the synchronizing member 51 can rotate with the compression part 6, so as to realize the switching of the motion states of the inner valve core 31, the outer valve core 32 and the transfer bin 3.

[0024] As a further solution of the present invention, a connecting ring 34 is fixedly provided at the top of the transfer bin 3, and the outer diameter of the connecting ring 34 is between the inner diameter of the bottle mouth at the top of the bottle body 1 and the inner diameter of the bottom of the sealing cap 2; Specifically, Figure 3 and Figure 8 , before installing the sealing cap 2, first insert the transfer bin 3 into the bottle mouth of the bottle body 1, and then install the sealing cap 2. In this embodiment, the sealing cap 2 is threadedly connected to the bottle body 1. The top of the inner side of the sealing cap 2 and the bottle mouth of the bottle body 1 clamp the connecting ring 34 therein. The installation of the sealing cap 2 realizes the fixation of the transfer bin 3 at the same time. The transfer bin 3 is convenient to disassemble, and is convenient for replacement or cleaning.

[0025] As a further solution of the present invention, a ventilation hole 41 communicating with the top of the compression part 6 is provided at the top of the pressing cap 4; During the spraying state, when pressing down the pressing cap 4, use a finger to block the ventilation hole 41 at the same time, so that the top of the upper switching part 63 is in a closed state, which can increase the resistance required for the upper switching part 63 to rise, delay the time when the upper groove 65 communicates with the horizontal groove 61, can increase the pressure inside the transfer bin 3, increase the pressure when the liquid medicine is sprayed, and increase the initial spraying speed of the liquid medicine (by controlling the time and strength of the finger blocking the ventilation hole 41, the initial spraying speed and strength of the liquid medicine can be dynamically adjusted), reduce the pressing force of the pressing cap 4, and the pressing cap 4 gradually returns to its original position under the action of elastic force. At the initial stage of the rise of the pressing cap 4, keep the top of the ventilation hole 41 blocked. Since the gas at the top of the upper switching part 63 is compressed, and the part where the bottom of the upper switching part 63 communicates with the transfer bin 3 decreases as the pressure inside the transfer bin 3 decreases, under the action of the pressure difference between the upper and lower parts of the upper switching part 63, the reset of the upper switching part 63 can be accelerated, and the extraction amount and accuracy of the liquid medicine can be improved; During the liquid return state, when pressing down the pressing cap 4, use a finger to block the ventilation hole 41 at the same time, so that the top of the upper switching part 63 is in a closed state, which can increase the resistance required for the upper switching part 63 to rise, ensure that the outer valve core 32 can move first, so as to connect the transfer bin 3 with the bottle body 1, and facilitate the liquid medicine to flow back.
