It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Please refer to Figure 1 and Figure 2As shown, a breathing synchronization device includes a housing 1, the housing 1 includes an upper cover 7, an upper shell 8 and a lower shell 9 which are coaxially connected and connected in sequence in a first direction. Optionally, the upper cover 7, the upper shell 8 and the lower shell 9 can be connected by a snap connection, which saves time during assembly, improves assembly efficiency, and is convenient for disassembly and replacement; the first direction is Figure 1 Middle vertical direction; Furthermore, a medicine bottle 3 is movably arranged inside the shell 1, and the medicine bottle 3 includes a bottle body, a telescopic rod that is arranged at the bottom of the bottle body and can be extended and retracted, and a nozzle 4 that is connected to the telescopic rod and sprays medicine. A suction nozzle 2 that is connected to the inside of the shell 1 is arranged at the bottom of the lower shell 9, and the nozzle 4 faces the suction nozzle 2, so that the medicine can be inhaled into the mouth of the patient.

[0028] A pushing component, which is movably disposed inside the housing 1 and located on the top of the medicine bottle 3, and is used to push the medicine bottle 3 to move along a first direction to spray the medicine; Specifically, the pushing assembly includes a mounting seat 14, which is arranged inside the upper shell 8. The circumferential inner wall of the upper shell 8 has a first abutment portion, and the circumferential side wall of the mounting seat 14 has a second abutment portion, the second abutment portion is located on the top of the first abutment portion and abuts against the first abutment portion. Two first hinged portions 15 are arranged at the bottom of the mounting seat 14 along the second direction, and the two first hinged portions 15 are symmetrically arranged about the axis of the mounting seat 14; the second direction is Figure 1 a middle horizontal direction, and a second direction perpendicular to the first direction; Furthermore, the pushing assembly further comprises a pushing seat 16, which is movably disposed in the upper shell 8, and two second hinged parts 17 are disposed on the top of the pushing seat 16 for the two first hinged parts 15; Furthermore, the pushing assembly further includes two first connecting rod groups corresponding to the two first hinged portions 15 respectively, and the two first connecting rod groups each include a first connecting rod 18 and a second connecting rod 19, one end of the first connecting rod 18 is hinged to the first hinged portion 15, and the other end is hinged to one end of the second connecting rod 19, and one end of the second connecting rod 19 away from the first connecting rod 18 is hinged to the second hinged portion 17; Further, the pushing assembly also includes a second connecting rod group, which is located between the two first connecting rod groups. The second connecting rod group includes two third connecting rods 20, one end of the two third connecting rods 20 is hinged, and the ends of the two third connecting rods 20 that are far away are respectively hinged to one end of the first connecting rod 18 and the second connecting rod 19 in the two first connecting rod groups; The pushing assembly has a first state and a second state. When the pushing assembly is in the first state, the device as a whole is in an initial state. At this time, the axes of the two third connecting rods 20 coincide with each other and are parallel to the second direction. The axes of the first connecting rods 18 and the second connecting rods 19 of the two first connecting rod groups intersect, so that the resultant forces between the first connecting rods 18 and the second connecting rods 19 are all along the second direction, thereby offsetting the resultant forces of the two first connecting rod groups on the second connecting rod group, so that the two third connecting rods 20 are in dead point balance, preventing the pushing seat 16 from moving. When the pushing assembly is in the second state, the device has completed spraying the medicine. At this time, the axes of the two third connecting rods 20 intersect, the dead point balance is broken, and the pushing seat 16 moves downward along the first direction to push the medicine bottle 3 to squeeze the nozzle 4, so that the nozzle 4 can spray the medicine.

[0029] Two slide grooves 27 are symmetrically arranged on the inner wall of the upper shell 8 about its axis, and two slide plates 28 are arranged on the side wall of the push seat 16 corresponding to the two slide grooves 27. The two slide plates 28 are respectively slidably arranged in the two slide grooves 27, so that the push seat 16 can be guided and limited when moving, and the push seat 16 can stably move along the first direction; Furthermore, a second through hole 29 is formed at the center of the bottom of the upper shell 8 along the first direction, and a pushing portion is provided at the bottom of the pushing seat 16. The pushing portion moves along the first direction through the second through hole 29 and extends into the lower shell 9, and is connected with a pushing block 30, and the bottom of the pushing block 30 contacts the top of the medicine bottle 3. Optionally, a screw hole is provided at the bottom of the pushing portion, and the pushing block 30 is screwed into the screw hole by a screw, so that the pushing block 30 is installed at the bottom of the pushing portion.

[0030] The push assembly further includes a push rod 21, which extends along the first direction. A through hole 10 is formed at the center of the upper cover 7 along the first direction. A first through hole 23 is formed on the mounting seat 14 along the first direction. The bottom of the push rod 21 is movable through the through hole 10 and the first through hole 23 in sequence to extend to the interior of the upper shell 8, and a third hinged portion 24 is provided. One end of the two third connecting rods 20 is hinged to the third hinged portion 24. Further, a pulling block 22 is provided at the top of the push rod 21. Optionally, a screw hole is provided at the top of the push rod 21, and the pulling block 22 is screwed into the screw hole by a screw, so that the pulling block 22 is installed at the top of the push rod 21. It should be noted that the top of the upper cover 7 has a recessed portion for accommodating the pulling block 22 .

[0031] The toggle assembly is arranged inside the housing 1 and is in transmission connection with the push assembly, and is used to drive the push assembly to switch from the first state to the second state when deformed by the suction force of the suction nozzle 2; Specifically, the toggle assembly includes a breathing valve 25, which is fixedly arranged in the upper shell 8 and located above the mounting seat 14. The breathing valve 25 is sleeved on the push rod 21, and the push rod 21 is provided with a clamping portion 26 for clamping the breathing valve 25. Furthermore, a plurality of first vent holes 11 are formed on the upper cover 7, and the plurality of first vent holes 11 all penetrate the upper cover 7 along the first direction, and the plurality of first vent holes 11 are evenly distributed around the through hole 10; Furthermore, a communication cavity is formed between the breathing valve 25 and the first vent hole 11, and the communication cavity is connected to the outside of the shell 1 and isolated from the inside of the shell 1; Furthermore, a plurality of second ventilation holes 12 are provided on the inner wall of the bottom of the upper shell 8. The plurality of second ventilation holes 12 all penetrate the inner wall of the bottom of the upper shell 8 along the first direction and are evenly distributed around the second through hole 29. Thus, the upper shell 8 and the lower shell 9 are connected and isolated from the outside of the shell 1 by the breathing valve 25. Air is sucked through the suction nozzle 2 to form a vacuum inside the shell 1. Under the action of the air pressure outside the shell 1, the breathing valve 25 is deformed, driving the push rod 21 to move downward along the first direction, so that the third hinge part 24 moves downward, breaking the dead point balance between the two third connecting rods 20, and then the push seat 16 and the push block 30 move downward, pushing the medicine bottle 3 to squeeze the nozzle 4 to spray the medicine; It should be noted that the breathing valve 25 is made of soft material, and can be made of silicone. When the push assembly is in the first state, the breathing valve 25 itself can also provide a certain support force for the push rod 21 to prevent the push rod 21 from moving; It should be noted that the circumferential edge of the breathing valve 25 overlaps the top circumferential edge of the mounting seat 14, and the bottom circumferential edge of the upper cover 7 is crimped onto the top of the circumferential edge of the breathing valve 25, thereby achieving the clamping of the breathing valve 25 by the upper cover 7 and the mounting seat 14, further avoiding the displacement of the breathing valve 25, increasing the stability of the breathing valve 25, and preventing air leakage.

[0032] The bottom inner wall of the upper shell 8 is provided with a receiving groove, which is located between the second vent hole 12 and the second through hole 29, and the magnet 5 is arranged inside the receiving groove; Further, the first magnetic member 6 is arranged on the pushing seat 16. Specifically, the top of the pushing seat 16 has a mounting portion, and the first magnetic member 6 is covered on the mounting portion. When the pushing assembly is in the first state, the magnet 5 and the first magnetic member 6 are separated from each other. When the pushing assembly is in the second state, the magnetic force of the magnet 5 attracts the first magnetic member 6. It should be noted that the pushing seat 16 can be selected to be a lightweight material, such as plastic, and the first magnetic attraction member 6 can be selected to be an iron sheet, which is covered on the mounting portion. The purpose is to reduce the weight of the pushing seat 16 and avoid the pushing seat 16 from moving downward due to being too heavy, thereby avoiding the pushing seat 16 from moving downward due to being too heavy when the pushing assembly is in the first state, thereby breaking the dead point balance of the two third connecting rods 20.

[0033] It should be noted that seals may be provided between the upper cover 7 and the upper shell 8 , and between the upper shell 8 and the lower shell 9 , for isolating the air so that the inside and outside of the housing 1 are isolated. Optionally, the seals may be rubber sealing rings.

[0034] It should be noted that a receiving groove is provided at the center of the top of the upper cover 7 and at the center of the top inner wall, the receiving groove is connected to the through hole 10, a second magnetic member 31 is provided in the receiving groove at the center of the top of the upper cover 7, and a third magnetic member 32 is movably provided in the receiving groove at the center of the top inner wall of the upper cover 7, wherein the third magnetic member 32 is fixedly connected to the push rod 21; Furthermore, when the pushing component is in the first state, the two third connecting rods 20 are in dead point balance, their axes coincide with each other, and the second magnetic member 31 and the third magnetic member 32 are attracted to each other, so as to prevent the pushing component from sinking due to gravity and change the state of the pushing component, thereby increasing reliability; Optionally, the second magnetic attraction member 31 and the third magnetic attraction member 32 may be a pair of magnets, or a magnet and an iron block.

[0035] Working principle: Before use, the pushing assembly is in the first state, and the device as a whole is in the initial state. At this time, the two third connecting rods 20 are in dead point balance, their axes coincide with each other, and the first magnetic attraction member 6 is away from the magnet 5; When in use, the patient takes the device and removes the nozzle cap 13, puts the nozzle 2 into the mouth, covers the nozzle 2 with the lips, and then inhales. Under the action of suction, the gas inside the shell 1 is sucked in, thereby forming a vacuum state inside the shell 1. The external air pressure causes the respiratory valve 25 to deform, driving the push rod 21 to move downward along the first direction, and the third hinge part 24 to move downward, breaking the dead point balance between the two third connecting rods 20, pushing the seat 16 and the push block 30 to move downward, so that under the magnetic force of the magnet 5, there is suction on the first magnetic component 6, and further force is applied to push the seat 16 and the push block 30 downward, and then the magnet 5 absorbs the first magnetic component 6, pushing the seat 16 and the push block 30 to move downward, pushing the bottle body downward, squeezing the nozzle 4, and the medicine is sprayed out. At this time, the pushing component is in the second state, and the device completes the medicine spraying. The medicine is sucked into the patient's body from the nozzle 2, thereby achieving the synchronization of inhalation and inhalation of medicine. The operation is simple, the sensitivity is high, the stability and reliability are high, the cost is low, and it is easy to achieve mass production. After use, the pulling block 22 is pulled upward to drive the push rod 21 upward, thereby the third hinge part 24 moves upward, so that the two third connecting rods 20 return to the dead point equilibrium state, and the pushing assembly returns to the first state, thereby driving the pushing seat 16 and the pushing block 30 to move upward, the first magnetic suction part 6 moves away from the magnet 5, and the pushing seat 16 moves away from the medicine bottle 3, the squeeze on the medicine bottle 3 is released, the bottle body automatically resets under the action of the telescopic rod, and the device as a whole returns to the initial state.

[0036] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
