Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an adjustable spray weight tube frame structure and spray device. Background Technology

[0002] In related technologies, the container portion of a spraying device (or atomizing device) contains liquid, and as the container portion moves relative to the nozzle portion of the spraying device, the liquid can be atomized and released outward from the nozzle portion.

[0003] In existing spraying devices, the weight of the spray produced each time is basically consistent. The principle behind this is to achieve quantitative spraying through a tube support structure. For example, in Chinese patent CN 117427246 A, the infusion tube and the tube support are integrated into one unit. Since the distance between the second helical surface of the tube support and the first helical surface of the cavity is constant, the upward or downward movement of the infusion tube is always constant, thereby achieving the quantitative spraying function.

[0004] For manufacturers, in order to meet the needs of different patients, spray devices with different spray weights need to correspond to tube frame structures of different sizes. This leads to manufacturers having to develop different models of tube frame molds, resulting in disadvantages such as high production costs and low efficiency.

[0005] For users, as their condition improves or worsens, they need to flexibly control the spray weight to ensure optimal treatment results. The current integrated design means the tube frame structure lacks the function of adjusting the spray weight, requiring users to prepare two or even more spray devices depending on their condition, which is costly and inconvenient to carry.

[0006] Based on the above problems, this application proposes an adjustable spray weight pipe rack structure and spraying device. Summary of the Invention

[0007] The purpose of this invention is to provide an adjustable spray weight tube frame structure and spray device. By designing the tube frame structure in two parts, the relative position of the frame and the infusion tube can be adjusted, thereby changing the spray weight of the spray device and effectively reducing the production cost for manufacturers and the usage cost for patients.

[0008] The objective of this invention is achieved through the following technical solution:

[0009] An adjustable spray weight tube frame structure includes a frame body and an infusion tube, wherein a matching component is fixedly connected to the infusion tube; wherein the matching component is movably assembled in the frame body, so that the distance from the upper end of the infusion tube to the upper end of the frame body is adjustable.

[0010] In the above solution, the frame and infusion tubing are designed as separate units, and their relative positions are adjustable, allowing for flexible changes in spray weight to meet different usage environments. For manufacturers, only one set of molds is needed to produce tubing frame structures with different spray weights, effectively reducing production costs. Furthermore, the separate molding process results in higher injection molding precision and better product yield. For users, adjusting the spray weight to suit different usage environments facilitates use while reducing procurement costs.

[0011] In some embodiments, the frame body is provided with a through hole, and the mating part is threadedly connected to the through hole.

[0012] In the above solution, the threaded adjustment method is used. By adjusting the screwing depth of the matching parts, the distance between the upper end of the infusion tube and the upper end of the frame can be changed, thereby changing the spray weight of the tube frame structure. It has the advantages of simple operation and convenient adjustment.

[0013] In some embodiments, the frame body is provided with a through hole, and the mating member transitionally engages with the through hole.

[0014] In the above scheme, a transition fit is used. By pressing and adjusting the insertion depth of the matching parts, the distance between the upper end of the infusion tube and the upper end of the frame can also be changed, thereby adjusting the spray weight. However, it should be noted that the frictional force should be greater than the pump pressure of the infusion tube on the liquid to ensure the overall stability of the tube frame structure.

[0015] In some embodiments, a through hole is provided in the frame body, and at least one locking member is provided in the side wall of the frame body for pressing the mating member against the through hole.

[0016] In the above scheme, the lateral locking method is used. When the spray weight of the pipe rack structure needs to be adjusted, loosen the locking parts and adjust the insertion depth of the matching parts, then tighten the locking parts again. However, it should be noted that when the locking parts are tightened, they must be sunk into the side hole or at least flush with the surface of the rack to avoid interference with the movement of the pipe rack structure.

[0017] In some embodiments, the thickness of the through hole is greater than the thickness of the mating member.

[0018] In the above solution, the thicker through hole allows the frame to fully contact the mating part, ensuring the fixing effect between the two. In addition, the thicker through hole also provides sufficient space for the mating part, making it convenient for position adjustment.

[0019] In some embodiments, the adjustment distance between the upper end of the infusion tube and the upper end of the frame is ±10mm.

[0020] In the above scheme, the thickness difference range corresponds to the variable travel of the tube rack structure. This difference allows the tube rack structure to adjust the spray weight within a large range, meeting different usage environments and improving versatility.

[0021] In some embodiments, a spiral portion is provided on the inner side of the frame, which is used to cooperate with the upper shell portion of the rotating spray device to drive the infusion tube to move down and reset.

[0022] In some embodiments, the bottom of the frame is provided with a sleeve portion for connecting the container portion of the spraying device.

[0023] In some embodiments, the frame body is further provided with a protruding ring portion, which is used to cooperate with the upper shell portion of the spray device, thereby limiting the upward movement of the infusion tube.

[0024] In the above solution, the upward movement of the infusion tube is restricted twice by the convex ring, so that the spray weight is kept consistent for each spray, thereby improving the spray quality and effect.

[0025] In some embodiments, the outer periphery of the infusion tube is provided with a groove, and the mating part is partially embedded in the groove.

[0026] In the above solution, the groove design improves the bonding strength between the infusion tube and the matching parts, preventing axial movement of the infusion tube and affecting the spraying effect.

[0027] The present invention also provides a spraying device, including the adjustable spray weight tube frame structure described above.

[0028] In the above solution, the spray device equipped with the pipe rack structure has the function of adjusting the spray weight, which can meet the needs of different usage scenarios and is convenient to use.

[0029] In some embodiments, the spraying device further includes:

[0030] The upper shell portion has a through cavity at its center and a guide portion on its outer periphery.

[0031] The nozzle portion is disposed within the cavity portion, and the nozzle portion is provided with a fluid channel;

[0032] The main rotating body is rotatably connected to the upper shell portion, wherein the tube frame structure is disposed within the main rotating body and can move up and down as it rotates;

[0033] An actuator is disposed above the main rotating body, and the actuator is configured to lock the tube rack structure after the liquid loading state ends and unlock the tube rack structure before the spraying state.

[0034] A spring is located below the tube rack structure and is in a compressed state when the tube rack structure is locked.

[0035] Compared with the prior art, the beneficial effects of the present invention include at least the following:

[0036] 1. By designing the frame and infusion tube separately, the relative positions of the frame and infusion tube are adjustable, which allows for flexible changes in spray weight to meet the needs of different usage scenarios.

[0037] 2. Effectively reduces the production costs for manufacturers and the usage costs for patients.

[0038] 3. The structure for adjusting the spray weight is simple and easy to operate. Attached Figure Description

[0053] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0054] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0055] The spray weight involved in this invention refers to the weight of atomized particles that a spray device can produce per unit time, which is an important indicator for evaluating the performance of the spray device. The spray weight of the spray device depends on the pipe support structure, specifically determined by the travel distance of the upper end of the infusion tube 2, as detailed below. Figures 6 to 12 As shown.

[0056] As shown in the figure, the spraying device generally includes an upper shell 5, a nozzle 7, a main rotating body 8, a pipe frame structure, an actuator 9, and a spring 10.

[0057] The upper shell portion 5 is generally a convex cylindrical structure with a central cavity 51, which is adapted in shape and size to the nozzle portion to achieve a stable holding effect. Furthermore, a guide portion 52 is provided on the outer periphery of the cavity 51, which is spirally arranged downwards and corresponds to the spiral portion 12 on the inner side of the frame 1 (see...). Figure 12 ), used to guide the rotation and downward movement of the pipe rack structure.

[0058] The nozzle part 7 is disposed within the cavity 51, and the two can be fixed together by interfering with each other, which facilitates assembly and disassembly. Furthermore, the nozzle part 7 is provided with a fluid channel 71, which is disposed in a flow guide member 72 connected to the cavity 51. The top of the channel is used to connect to the atomizing unit 73, and the bottom is used to connect to the infusion tube 2.

[0059] The main rotating body 8 is a cylindrical structure, and its top is inserted into the upper shell part 5 and rotatably connected to it. For example, the main rotating body 8 and the upper shell part 5 can be connected by the concave and convex structure 81 and can rotate relative to each other.

[0060] The pipe rack structure is housed within the main rotating body 8 and can move up and down as it rotates. Specifically, the frame 1 of the pipe rack structure and the main rotating body 8 are connected via a sliding groove structure 16 (see...). Figure 11 This allows the device to move up and down along its axial direction, thus achieving the functions of liquid loading and spraying.

[0061] Actuator 9 is a ring-shaped structure, positioned above the main rotating body 8. Actuator 9 is configured to lock the pipe rack structure after the liquid loading state ends and unlock the pipe rack structure before the spraying state. For example... Figure 8 As shown, when actuator 9 intersects eccentrically with main rotating body 8, actuator 9 presses against the locking pipe support structure and places it in the liquid-filled state. (Continue to see...) Figure 9 As shown, when the actuator 9 is translated to be coaxial and collinear with the main rotating body 8, the actuator 9 releases the pressure on the pipe rack structure, and the pipe rack structure can move upward under the action of external force (such as a compressed spring 10), thereby entering the spraying state.

[0062] In both of the above states, the spraying state can be transitioned to the liquid loading state by rotating the main rotating body 8, and the liquid loading state can be switched to the spraying state by pressing the actuator 9. More specifically, as... Figure 10 As shown, a reset member 91 is provided on the side of the actuator 9 away from the pressing side. The reset member 91 is provided with a first deflecting surface 911. Correspondingly, mating members 82 are symmetrically provided on both sides of the upper end of the main rotating body 8. The mating members 82 are provided with a second deflecting surface 821. Every time the main rotating body 8 rotates 180°, the second deflecting surface 821 on the mating member 82 contacts the first deflecting surface 911 on the reset member 91 once, driving the actuator 9 to translate and intersect the main rotating body 8 eccentrically, thereby pressing and fixing the downward-moving tube rack structure. At this time, the device transitions to the liquid feeding state. When the actuator 9 is pressed and translated to be coaxial and collinear with the main rotating body 8, the actuator 9 releases the pressure on the tube rack structure. The spring 10 located below the tube rack structure (which is in a compressed state at this time) can quickly push it upward. At this time, the device switches to the spraying state.

[0063] The spray device is used as follows:

[0064] S1. Mount the container part 6 onto the tube rack structure and insert the lower end of the infusion tube 2 into the container part 6 to contact the liquid.

[0065] S2. Press the actuator 9 to move it to the same axis as the main rotating body 8 to unlock the tube rack structure. The spring 10 pushes the tube rack structure upward, and the infusion tube 2 moves toward the nozzle part 7 and compresses the space of the fluid channel 71, so that the liquid in the channel is pressurized and sprayed outward in the form of a mist.

[0066] S3. Rotate the main rotating body 8. The frame 1 of the tube rack structure rotates synchronously. Relying on the guiding cooperation after the spiral part 12 contacts the guide part 52, the tube rack structure moves down to reset and compresses the spring 10. During this period, the infusion tube 2 moves away from the nozzle part 7 and evacuates the fluid channel 71. The liquid in the container part 6 is pumped into the fluid channel 71. At the same time, the mating part 82 on the main rotating body 8 rotates to contact the reset part 91 of the actuator 9 and drives the actuator 9 to translate and intersect the main rotating body 8 eccentrically again to lock the tube rack structure.

[0067] S4. Repeat steps S2 and S3 to achieve continuous spraying.

[0068] Because the length of existing integrated tube rack structures is not adjustable, the spray weight is almost constant, generally ranging from 12.5 mg to 13.5 mg, which cannot meet the needs of different environments. Therefore, this invention discloses a tube rack structure with adjustable spray weight, as shown in Figure 1 to 2018. Figure 5 As shown, the tube rack structure adopts a split connection design, including the rack body 1 and the infusion tube 2, and the relative position of the two is adjustable.

[0069] Specifically, the frame 1 is generally sleeve-shaped, and preferably has a through hole 11 at the center of its interior. This hole has a certain thickness to ensure the stability of the connection. Correspondingly, a matching part 3 is fixedly connected to the infusion tube 2. This part is located in the middle of the infusion tube 2 and corresponds to the through hole 11.

[0070] During assembly, the matching component 3 is placed inside the through hole 11. By adjusting the position of the matching component 3 within the through hole 11, the distance between the upper end of the infusion tube 2 and the upper end of the frame 1 can be changed, thereby obtaining tube frame structures with different spray weight controls. Specifically, when the upper end of the infusion tube 2 moves upward relative to the upper end of the frame 1, the travel distance of the infusion tube 2 within the fluid channel 71 decreases, and the corresponding spray weight also decreases; when the upper end of the infusion tube 2 moves downward relative to the upper end of the frame 1, the travel distance of the infusion tube 2 within the fluid channel 71 increases, and the corresponding spray weight also increases.

[0071] For example, such as Figure 3As shown, the matching part 3 can be threadedly connected to the through hole 11. In this example, the inner side of the through hole 11 is provided with an internal thread, and the outer periphery of the matching part 3 is provided with an external thread. During assembly, the matching part 3 is rotated and screwed into the through hole 11 to connect the frame 1 and the infusion tube 2. Furthermore, by adjusting the screwing depth of the matching part 3, the distance between the upper end of the infusion tube 2 and the upper end of the frame 1 can be changed, thereby changing the spray weight of the tube frame structure. It has the advantages of simple operation and convenient adjustment.

[0072] Or, such as Figure 4 As shown, the matching part 3 can also transition into the through hole 11. In this example, the matching part 3 and the frame 1 are joined together by friction. By pressing and adjusting the insertion depth of the matching part 3, the distance between the upper end of the infusion tube 2 and the upper end of the frame 1 can also be changed, thereby adjusting the spray weight. However, it should be noted that the aforementioned friction force should be greater than the pumping pressure of the infusion tube 2 on the liquid to ensure the overall stability of the tube frame structure.

[0073] For example, see Figure 5 As shown, at least one locking element 4 is provided in the side wall of the frame 1. In this example, a side hole 15 communicating with the through hole 11 is provided on the side wall of the frame 1, and the diameter of the side hole 15 matches the locking element 4. During assembly, the matching element 3 is inserted into the through hole 11, and then the locking element 4 is tightened until the locking element 4 presses the matching element 3 into the through hole 11. When it is necessary to adjust the spray weight of the pipe rack structure, loosen the locking element 4 and adjust the insertion depth of the matching element 3, and then tighten the locking element 4 again. Note that when the locking element 4 is tightened, it must be sunk into the side hole 15 or at least flush with the surface of the frame 1 to avoid interference with the movement of the pipe rack structure.

[0074] It should be understood that the position adjustment methods between the frame 1 and the infusion tube 2 are not limited to the three methods mentioned above; other methods that can achieve the above functions are also feasible. In this application, the adjustment distance from the upper end of the infusion tube 2 to the upper end of the frame 1 is approximately ±10mm. This range corresponds to the variable travel of the tube frame structure, allowing the tube frame structure to adjust the spray weight within a wide range, for example, within the spray weight range of 11.5 mg to 14.5 mg, thereby meeting different usage environments and improving versatility. Preferably, the adjustment distance from the upper end of the infusion tube 2 to the upper end of the frame 1 can be ±6mm, ±8mm, etc.

[0075] See Figure 2a and Figure 2b As shown, in some embodiments, the thickness of the through hole 11 is greater than the thickness of the mating member 3. This allows the frame 1 to fully contact the mating member 3, ensuring a secure connection between them; furthermore, the thicker through hole 11 also provides ample space for the mating member 3, facilitating position adjustment.

[0076] In summary, the tube rack structure of this application, by designing the frame 1 and the infusion tube 2 as separate units, allows for adjustable relative positions between the frame 1 and the infusion tube 2, thus enabling flexible changes in spray weight to meet different usage environments. For manufacturers, only one set of molds is needed to produce tube rack structures with different spray weights, effectively reducing production costs. Furthermore, the injection molding precision of the separate units is higher, resulting in better product yield. For users, adjusting the spray weight to suit different usage environments facilitates use while reducing procurement costs.

[0077] See Figure 6 and Figure 7 As shown, the bottom of the frame 1 is provided with a retaining sleeve 13, which is used to connect the container part 6 of the spray device. The container part 6 usually contains a specific medicine or a non-therapeutic liquid such as saline or perfume. After being installed in the retaining sleeve 13, it can be supplied to the nozzle of the spray device through the infusion tube 2. Preferably, the retaining sleeve 13 can be connected to the container part 6 by snap-fit, which is convenient for disassembly and replacement.

[0078] In addition, a spiral part 12 is provided on the inner side of the frame 1. The spiral part 12 is used to cooperate with the upper shell part 5 of the rotating spray device. Under the action of the guide part 52, it can control the overall rotation and downward movement of the tube frame structure, causing the infusion tube 2 to move down and reset and switch to the infusion state.

[0079] Furthermore, a protruding ring 14 is provided inside the frame 1. The protruding ring 14 is arranged around the upper end of the through hole 11 and is used to cooperate with the upper shell part 5 of the spray device. It can abut against the through cavity part 51, thereby limiting the upward movement of the tube frame assembly (i.e., the infusion tube 2), so that the spray weight of each spray is consistent, and the spray quality and effect are improved.

[0080] Preferably, in the above-mentioned tube frame structure, the sleeve portion 13, the spiral portion 12 and the convex ring portion 14 can all be integrally injection molded with the frame body 1.

[0081] See Figure 2a and Figure 2b As shown, the outer periphery of the infusion tube 2 is provided with a groove 21, and the matching part 3 is partially embedded in the groove 21, thereby improving the bonding strength between the infusion tube 2 and the matching part 3 and preventing the infusion tube 2 from axially moving and affecting the spraying effect.

[0082] In addition, the inner top of the infusion tube 2 is provided with a one-way structure 22, which can be a one-way valve formed by the inner cavity of the tube and the valve core, to prevent liquid backflow when the infusion tube 2 pumps the liquid, thus ensuring the reliability of the spray.

[0083] The present invention also discloses a spraying device, such as a nasal spraying device, which includes the aforementioned adjustable spray weight tube frame structure. This enables the spraying device to have the function of adjusting the spray weight, which can meet the needs of different usage scenarios and is convenient to use.

[0084] In this spraying device, although the distance between the spiral part 12 and the guide part 52 is constant, if the spray weight needs to be adjusted, without significantly altering the structure of the spraying device, it is only necessary to simply adjust the relative position of the infusion pipe 2 and the frame 1, thereby changing the travel distance of the infusion pipe 2 in the fluid channel 71, which can change its own spray weight. This has the advantages of simple operation and low modification cost.

[0085] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the invention without departing from the principles and spirit of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
