[0047] The names of the messages or information exchanged between multiple devices in the embodiments of the present application are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0048] Reference Figures 1-6 and Figure 11 , an adjustable powder spraying medicine bottle with a switch structure, comprising a bottle body 1 and a bottle cap 2, the bottle body 1 and the bottle cap 2 are both made of PE, PP, PET and other materials by blow molding, and can undergo a certain elastic deformation, the bottle cap 2 is movably installed on the top of the bottle body 1, the main function of the bottle body 1 is to store medicine powder, and its internal space provides a place for containing medicine powder, the bottle cap 2 is installed on the top of the bottle body 1, on the one hand, it plays the role of sealing the bottle body 1, preventing the medicine powder from getting damp, contaminated or spilling when not in use, thereby ensuring the quality and effectiveness of the medicine powder, and serving as a carrier for installing other components, a rod part 3 for extracting medicine powder is movably installed in the bottle body 1, and when the bottle cap 2 is installed in the bottle body 1, it is in contact with the bottle body 1. The bottle body 1 together forms a relatively closed space, ensuring that the rod member 3 can effectively extract the powder when it moves in the bottle body 1 and prevent the powder from leaking from the connection part. The rod member 3 has a conductive channel 31 extending to the outside of both ends of the rod member 3. The conductive channel 31 extends to the outside of both ends, so that the powder can be transferred from the bottle body 1 to the top of the rod member 3 through the conductive channel 31, and then connected to the relevant structure in the bottle cap 2, thereby realizing further conduction of the powder. The conductive channel 31 serves as a key path for powder transmission, ensuring that the powder can be stably and smoothly transported from the inside of the bottle body 1 to the subsequent conductive structure, providing a prerequisite for the spraying of the powder.

[0049] A limiting portion 22 is provided in the bottle cap 2, and a limiting groove 221 is provided at the bottom of the limiting portion 22. When the bottle cap 2 is installed in the bottle body 1, the top of the rod part 3 is embedded in the limiting groove 221. The limiting portion 22 is also provided with a receiving groove 222. The bottle cap 2 has an opening 21 connected to the receiving groove 222. The limiting groove 221 is provided with an overflow hole 223 connected to the receiving groove 222. The aperture size of the overflow hole 223 can control the flow rate of the powder, prevent the powder from entering the receiving groove 222 too quickly or too much, and play a role in regulating the powder transmission amount. The limiting groove 221 plays a role in limiting the top of the rod part 3. The positioning and limiting functions ensure that when the rod member 3 moves in the bottle body 1, its top is always in a specific position and will not deviate or shake. This limiting function ensures the accurate cooperation between the rod member 3 and other structures in the bottle cap 2, so that the conductive channel 31 can maintain a stable communication state with the overflow hole 223, thereby ensuring that the powder can smoothly enter the overflow hole 223 from the conductive channel 31, and then enter the receiving groove 222 and the opening 21. At the same time, the provision of the limiting groove 221 can also limit the range of movement of the rod member 3 to a certain extent, preventing excessive movement from causing structural damage or functional failure.

[0050] The nozzle part 4 is also included. The nozzle part 4 includes a connecting portion 41. The connecting portion 41 has a guide rod 42 and a discharge rod 43 distributed vertically. The nozzle part 4 forms an L-shaped structure distribution. The guide rod 42 and the discharge rod 43 are connected to each other and form a discharge channel 44. Part of the guide rod 42 passes through the opening 21 and is embedded in the accommodating groove 222. When the guide rod 42 is located in the accommodating groove 222, the guide rod 42 fits with the inner wall of the accommodating groove 222, thereby enhancing the damping of the guide rod 42 when it is installed in the accommodating groove 222, so that the discharge channel 44 and the conduction channel are connected. The channel 31 is connected through the overflow hole 223. The accommodating groove 222 serves as an intermediate storage and transition space for powder transmission, receiving the powder flowing out of the overflow hole 223. After the rod body 3 transports the powder through the conductive channel 31 and the overflow hole 223 to the accommodating groove 222, the accommodating groove 222 can temporarily store a certain amount of powder. This allows the powder to pass through multiple corners during the spraying process, preventing the powder from directly impacting the nozzle component 4. This buffers and stabilizes the powder flow rate, making the spraying of the powder gentle and less likely to cause throat clogging.

[0051] Through the cooperation between the guide rod 42 and the opening 21, the connecting part 41 has the freedom of rotation with the guide rod 42 as the center, and the discharge rod 43 rotates synchronously. The freedom of rotation enables the nozzle component 4 to be adjusted in angle. The user can rotate the nozzle component 4 according to actual needs and adjust the direction of the discharge rod 43, thereby realizing powder spraying in different directions, thereby improving the flexibility and applicability of the medicine bottle.

[0052] Based on the above structure, the rod body part 3 is installed in the bottle body 1 loaded with powder, and the bottle cap 2 is connected to the bottle body 1, and the guide rod 42 of the nozzle part 4 enters the receiving groove 222 through the opening 21, so as to realize the installation of the nozzle part 4 and the bottle cap 2. When the user presses the bottle body 1, the air space above the powder in the bottle body 1 is compressed to form an instantaneous positive pressure. When the pressure is released, a negative pressure is formed in the bottle, and the rod body part 3 sucks in the powder and transports the powder to the guide rod 42 of the nozzle part 4 through the overflow hole 223. This reciprocating motion realizes the hierarchical transmission of the powder from the bottle body 1 to the bottle cap 2, and the powder is transported to the bottle cap 2. The powder can be buffered during the process of entering the guide rod 42, thereby optimizing the flow rate of the powder to form a uniform powder mist and improving the use effect. The discharge rod 43 used to spray the powder can be matched with the gap between the guide rod 42 and the opening 21 provided in the bottle cap 2 to give the discharge rod 43 circumferential rotation freedom, so that the user can adjust the direction of the discharge rod 43 according to needs to achieve multi-angle precise powder spraying. The setting of the nozzle component 4 can realize the rotation of the nozzle direction, and optimize the flow rate of the powder, improve the use experience, and solve the problem of the single-function design of the existing medicine bottle, which is only suitable for flat spraying and cannot meet the needs of diversified scenarios.

[0053] In one embodiment, referring to Figure 1-Figure 5 By moving the guide rod 42 in the receiving groove 222, the nozzle component 4 has an open state and a closed state. In the open state, the powder in the bottle body 1 can be sprayed by pressing the bottle body 1, and in the closed state, it is sealed;

[0054] When in the open position, the guide rod 42 is away from the overflow hole 223, forming a powder flow area between the guide rod 42 and the receiving groove 222. The guide rod 42 and the interior of the rod body 3 are interconnected, allowing the powder in the medicine bottle to enter the guide rod 42 through this flow area. Because the guide rod 42 and the interior of the rod body 3 are interconnected, the powder can be smoothly transported along the conductive channel 31 of the rod body 3 to other parts of the spray head 4, and finally sprayed out of the spray head. This design ensures an unobstructed flow path for the powder, ensuring a smooth powder spraying process.

[0055] When in the closed state, the guide rod 42 is in contact with the end face of the accommodating groove 222, and the outer periphery of the guide rod 42 blocks the overflow hole 223. The flow range of the powder is isolated by blocking and sealing, so that the powder cannot enter the area between the guide rod 42 and the accommodating groove 222 through the overflow hole 223, thereby blocking the flow path of the powder, thereby effectively preventing the powder from accidentally flowing out when not in use, avoiding waste and pollution of the powder, and also ensuring the safety of the medicine bottle during carrying and storage.

[0056] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 9 , and also includes a plugging piece 5, the plugging piece 5 has a card groove 51 that runs through one side of the plugging piece 5, and a sealing sleeve 431 is provided at the outer periphery of the bottom of the discharge rod 43, and the sealing sleeve 431 is integrally formed with the discharge rod 43. When the plugging piece 5 is installed on the discharge rod 43, the sealing sleeve 431 is embedded in the card groove 51. The depth and width of the card groove 51 are designed according to the size of the sealing sleeve 431 to ensure that the sealing sleeve 431 can be completely embedded therein. The installation of the plugging piece 5 can be sealed at the outlet position to prevent the powder from leaking from the discharge rod 43 when it is not needed, and can effectively prevent external dust, moisture, etc. from entering the interior of the medicine bottle, thereby improving the overall sealing effect of the medicine bottle.

[0057] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 6 , the part of the guide rod 42 located inside the bottle cap 2 is provided with a first protrusion 421, and the accommodating groove 222 is provided with a notch 2221. When the nozzle component 4 is in the closed state, the first protrusion 421 is embedded in the notch 2221. The notch 2221 and the first protrusion 421 are in the shape of an annular groove and a protrusion. Since the bottle cap 2 is made of plastic material, appropriate external force can be applied to the components during installation to cause the material to undergo temporary elastic deformation, slightly squeezing the guide rod 42 or expanding the peripheral part of the opening 21, so that the first protrusion 421 The material can be restored to its original shape after being perforated and installed in place, achieving a tight fit. When the nozzle component 4 is in the closed state, the structure in which the first protrusion 421 is embedded in the notch 2221 can fix the guide rod 42, preventing the guide rod 42 from unnecessary movement in the accommodating groove 222, and in the closed state, the guide rod 42 needs to be tightly against the end face of the accommodating groove 222 and block the overflow hole 223. The cooperation between the first protrusion 421 and the notch 2221 can enhance the stability of this sealing state, avoid the displacement of the guide rod 42 due to external vibration or collision, thereby ensuring the sealing effect in the closed state and effectively preventing powder leakage.

[0058] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 8 The rod member 3 includes a conduit member 32 and a straw member 33. The conduit member 32 is movably mounted on the straw member 33. The rod member 3 is composed of the straw member 33 and the conduit member 32 located outside the straw member 33. The conductive channel 31 is formed by the conduit member 32 and the straw member 33 being interconnected. The straw member 33 is used to absorb the powder inside the bottle body 1 and transfer it through the conduit member 32.

[0059] The outer periphery of the conduit member 32 is provided with a stopper 321, and a sealing ring 322 is provided at the bottom ring of the stopper 321. The bottle body 1 has a convex seat 11. When the straw member 33 is located inside the bottle body 1, the outer periphery of the sealing ring 322 abuts against the inner wall of the convex seat 11, and the stopper 321 abuts against the top end face of the convex seat 11. The initial sealing of the bottle body 1 is achieved through the cooperation of the sealing ring 322 and the convex seat 11, and the bottle body 1 is sealed again through the balance between the stopper 321 and the convex seat 11. This double sealing structure The structure can effectively prevent the powder from leaking from the connection between the rod part 3 and the bottle body 1. The close contact between the sealing ring 322 and the inner wall of the boss 11 forms a circumferential seal to prevent the powder from overflowing from the side, and the abutment between the blocking gasket 321 and the top end face of the boss 11 forms an axial seal to prevent the powder from leaking from above. At the same time, the conduit part 32 is movably installed on the straw part 33, so that the rod part 3 can realize certain movable functions while ensuring the seal, thereby meeting the adjustable design requirements of the medicine bottle.

[0060] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 9 A needle core part 52 is provided in the card slot 51. When the plug 5 is connected to the discharge rod 43, the needle core part 52 is embedded in the opening of the discharge rod 43 to block the discharge channel 44. The discharge channel 44 is further blocked by the needle core part 52 to achieve dual control of the output of the powder. When the medicine bottle is not in use, the blocking effect of the needle core part 52 can more thoroughly prevent the powder from flowing out of the discharge channel 44, especially for some tiny gaps or possible leakage points, which can play a good protective role. The needle core part 52 has an inclined end, and an inclined groove is provided at the corresponding position on the discharge rod 43, thereby further improving the sealing during connection and playing a role of embedded positioning.

[0061] In one embodiment, referring to Figure 1-Figure 3 The outer periphery of the bottle cap 2 is provided with vertical bars 23. There are several vertical bars 23 and they are spaced apart along the circumference of the bottle cap 2. The distribution of the vertical bars 23 can enhance the friction when the user rotates the bottle cap 2 to avoid slipping.

[0062] Two groups of spaced-apart clips 411 are provided on the side of the connecting portion 41 facing the bottle cap 2. When the nozzle component 4 is in the closed state, part of the clip 411 is embedded between the two groups of vertical bars 23. The number, spacing and shape of the vertical bars 23 and the clip 411 match each other to ensure that the clip 411 can be accurately embedded between the two groups of vertical bars 23. By limiting the connecting portion 41 by embedding the clip 411 between the vertical bars 23 in the closed state, the nozzle component 4 can be positioned and fixed to prevent the nozzle component 4 from rotating or shifting on the bottle cap 2, thereby ensuring that the guide rod 42 is in the correct closed position. At the same time, when the nozzle component 4 is accidentally touched during non-use, the cooperation between the vertical bar 23 and the clip 411 can provide a certain resistance to avoid the nozzle component 4 from opening due to accidental touch, thereby improving the safety and reliability of the use of the medicine bottle.

[0063] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 10 The inner wall of the convex seat 11 is provided with a groove 111, and the outer periphery of the sealing ring 322 is provided with a second protrusion 3221 matching the groove 111. The groove 111 and the second protrusion 3221 are in the shape of an annular groove and protrusion, and their sizes match each other to ensure that the second protrusion 3221 can be embedded in the groove 111;

[0064] When the washer 321 abuts against the top end surface of the protrusion 11, the second protrusion 3221 is embedded in the groove 111, further enhancing the sealing effect between the sealing ring 322 and the inner wall of the protrusion 11, preventing the sealing ring 322 from sliding circumferentially during use, and at the same time avoiding the situation where the bottle body 1 is shaken or squeezed during carrying when the bottle cap 2 is not installed, causing the bottle body 1 to fall over and cause the powder in the bottle body 1 to scatter. At the same time, it also improves the stability and sealing of the connection between the rod part 3 and the bottle body 1, thereby improving the durability of the medicine bottle.

[0065] In one embodiment, referring to Figure 2 、 Figure 7 and Figure 10 The outer periphery of the convex seat 11 is provided with a convex thread 112, and the inner wall of the bottle cap 2 is provided with a thread groove 24 matching the convex thread 112. Through the cooperation of the convex thread 112 and the thread groove 24, the bottle cap 2 is threadedly connected to the bottle body 1. The pitch, tooth shape and other parameters of the convex thread 112 and the thread groove 24 conform to the standard thread design to ensure that the two can cooperate smoothly. The threaded connection allows the user to easily open or close the medicine bottle. At the same time, the threaded connection can provide a certain pre-tightening force to ensure that the connection between the bottle cap 2 and the bottle body 1 is tight, prevent the powder from leaking from the connection, and improve the overall sealing and reliability of the medicine bottle.

[0066] In one embodiment, referring to Figure 1-Figure 3 There is a ring-shaped support base pad 12 on the side of the bottle body 1 facing the ground. The support base pad 12 is formed integrally with the bottle body 1. The setting of the support base pad 12 can make the medicine bottle more stable when placed on a flat surface, avoiding the medicine bottle from tipping over due to the uneven bottom of the bottle body 1 or the small contact area, ensuring that the medicine powder is evenly distributed in the bottle, which is convenient for subsequent use.

[0067] In one embodiment, referring to Figure 1 、 Figure 2 and Figure 8 A powder suction base 331 is provided at the bottom of the suction tube member 33. The powder suction base 331 and the suction tube member 33 are formed as one body. The diameter of the powder suction base 331 gradually increases from one end of the suction tube member 33 to the other end. The cross-section of the powder suction base 331 is arranged in a trumpet-shaped structure. The powder suction base 331 is connected to the suction tube member 33. The trumpet-shaped structure of the powder suction base 331 can expand the powder suction range, so that the medicine bottle can more effectively absorb the powder in the bottle during use;

[0068] A rib portion 3311 is provided in the powder suction base 331. There are several rib portions 3311 and they are spaced apart along the circumferential direction of the powder suction base 331. The setting of the rib portions 3311 can enhance the structural strength of the powder suction base 331, prevent the powder suction base 331 from deforming when absorbing powder or being subjected to external pressure, and ensure the stability of the powder suction process. In addition, the intervals between the rib portions 3311 may play a certain guiding role in the flow of powder, so that the powder can enter the straw component 33 more smoothly, thereby improving the use effect of the medicine bottle.
