DETAILED DESCRIPTION

In the present disclosure, unless otherwise specified, the use of the terms "first", "second", etc. to describe various elements is not intended to limit the positional relationship, temporal relationship, or importance relationship of these elements, and such terms are only used to distinguish one element from another element. In some examples, the first element and the second element may refer to the same instance of the element, and in some cases, based on the description of the context, they may also refer to different instances.

The terms used in the description of various examples described in this disclosure are only for the purpose of describing specific examples and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element can be one or more. As used herein, the term "plurality" means two or more, and the term "based on" should be interpreted as "based at least in part on". In addition, the terms "and/or" and "at least one of..." cover any one of the listed items and all possible combinations.

In the scope of the present disclosure, "nebulizer" refers to a device for atomizing liquid. Generally, a nebulizer is used to atomize fluid (such as liquid medicine or similar fluid) and spray the atomized fluid into the mouth or nose of a user (such as a patient).

In the related art, liquid can be sprayed by triggering the atomizer. For example, the atomizer can be triggered by a mechanical method (such as pressing or rotating a switch). However, when the atomizer is not used for a period of time, the air in the pumping assembly or the nozzle may have a negative impact on the dosage accuracy when the fluid is atomized next time.

In view of this, an embodiment of the present disclosure provides a nebulizer, which can first discharge a first dose of fluid before the nebulizer is used for the first time or after the nebulizer has not been used for a long time, and this portion of fluid may not be inhaled by the user; after discharging the first dose of fluid, the nebulizer can continue to discharge a second dose of fluid for the user to inhale, thereby improving the dosage accuracy of the atomized fluid.

The following will describe the atomizer according to the exemplary embodiment with reference to Figures 1 to 12. Among them, Figure 1 is a perspective view illustrating the atomizer according to the exemplary embodiment; Figure 2 is a schematic diagram illustrating the atomizer according to the exemplary embodiment in the second position state; Figure 3 is a schematic diagram illustrating the atomizer according to the exemplary embodiment in the loading position state; Figure 4 is a schematic diagram illustrating the atomizer according to the exemplary embodiment in the first position state; Figure 5 is a schematic diagram illustrating the starter of the atomizer according to the exemplary embodiment; Figure 6 is a schematic diagram illustrating the delivery tube seat of the atomizer according to the exemplary embodiment; Figure 7 is a schematic diagram illustrating the first housing of the atomizer according to the exemplary embodiment; Figure 8 is a schematic diagram illustrating the second housing of the atomizer according to the exemplary embodiment; Figure 9 is a schematic diagram illustrating the second housing of the atomizer according to the exemplary embodiment cooperates with the starter; Figure 10 is another schematic diagram illustrating the atomizer according to the exemplary embodiment in the first position state; Figure 11 is another schematic diagram illustrating the atomizer according to the exemplary embodiment in the second position state; and Figure 12 is another schematic diagram illustrating the starter of the atomizer according to the exemplary embodiment.

In the scope of the present disclosure, the "loading position" may refer to loading the liquid in the atomizer to a position ready for outward spraying (e.g., loading from the tank into the pumping chamber). After reaching the "loading position", the delivery tube seat may be moved to the "first position" (i.e., the pre-spraying position) without user triggering, so that the pumping assembly pumps the first dose of fluid to the nozzle; in the "first position", if there is no triggering action of an external force, the atomizer cannot further perform atomization spraying, and only by, for example, performing a manual operation (e.g., pressing) to trigger the trigger assembly can the delivery tube seat be restored to the "second position" (i.e., the final spraying position). In the "second position", the atomizer can be operated again (e.g., twisted) to switch to the "loading position", so the "second position" may also be referred to as the initial position.

1 to 12 , the atomizer 1000 includes: a fluid reservoir (not shown in the figures); a nozzle 1010 for atomizing the fluid; a pumping assembly 1020 for pumping the fluid in the fluid reservoir to the nozzle 1010 for atomization; a first shell 1030; a delivery tube holder 1040, which is mechanically coupled to the first shell 1030 and can rotate relative to the first shell 1030; a first elastic member (not shown in the figures); and a starter 1050.

The first housing 1030 and the delivery tube holder 1040 are configured so that the delivery tube holder 1040 can move away from the first housing 1030 to the loading position when the delivery tube holder 1040 rotates relative to the first housing 1030, and the first elastic member is configured to store energy when the delivery tube holder 1040 moves away from the first housing 1030, and the delivery tube holder 1040 moves to the first position toward the first housing 1030 under the action of the first elastic member after reaching the loading position, so that the pumping assembly pumps the first dose of fluid to the nozzle 1010. And the trigger 1050 is configured to prevent the delivery tube holder 1040 from leaving the first position when the delivery tube holder 1040 moves to the first position; and is configured to release the delivery tube holder 1040 when triggered, so that the delivery tube holder 1040 continues to move to the second position toward the first housing 1030 under the action of the first elastic member, so that the pumping assembly pumps the second dose of fluid to the nozzle 1010, wherein the second dose is greater than the first dose.

It can be seen that the delivery tube seat 1040 in FIG. 2 is in the second position (also the initial position), the delivery tube seat 1040 in FIG. 3 is in the loading position, and the delivery tube seat 1040 in FIG. 4 is in the first position between the loading position and the second position. In the example, in the case of the loading position, the liquid medicine can be pumped from the storage tank to the pumping chamber located at the first housing 1030; in the case of the first position, the first dose of liquid medicine can be ejected outward from the pumping chamber through the nozzle; and in the case of the second position, the second dose of liquid medicine can be ejected outward from the pumping chamber through the nozzle. Accordingly, after the final injection is completed, the delivery tube seat 1040 in the second position is in the initial position of the next action cycle, so that it can move to the loading position again.

In the example, the first elastic member can be a spring or other elastic member, as long as it can store energy through elastic deformation. In the example, the first elastic member (such as a spring) can be arranged on the side of the delivery tube seat 1040 close to the first shell 1030, and when the delivery tube seat 1040 moves away from the first shell 1030, it undergoes tensile deformation to store energy, and when the first elastic member rebounds, the delivery tube seat 1040 can be pushed to the first position or the second position by pulling force; the first elastic member (such as a spring) can be arranged on the side of the delivery tube seat 1040 away from the first shell 1030, and when the delivery tube seat 1040 moves away from the first shell 1030, it undergoes compressive deformation to store energy, and when the first elastic member rebounds, the delivery tube seat 1040 can be pushed to the first position or the second position by thrust.

In an example, the actuator 1050 may have a surface for blocking the delivery tube seat 1040, and the position of the actuator 1050 relative to the delivery tube seat 1040 can change with the trigger, thereby releasing the delivery tube seat 1040. This achieves a reliable conversion of the delivery tube seat 1040 between the pre-spray and the second position. Accordingly, the convenience of use of the atomizer can be improved.

According to the sprayer of the embodiment of the present disclosure, since the delivery tube seat 1040 can move to the first position toward the first shell 1030 under the action of the first elastic member after reaching the loading position, the pumping component pumps the first dose of fluid to the nozzle 1010, and this part of the fluid may not be inhaled by the user, thereby expelling the residual air in the pumping component or the nozzle, so as to reduce the negative impact of air on the dosage accuracy when atomizing the fluid.

In addition, by triggering the starter 1050, the delivery tube seat 1040 can be released, so that the delivery tube seat 1040 continues to move toward the first shell 1030 to the second position under the action of the first elastic member, so that the pumping assembly pumps a second dose of fluid greater than the first dose to the nozzle 1010, and the second dose of fluid can be inhaled by the user, thereby improving the dosage accuracy of the atomized fluid while ensuring normal use by the user.

In an example, the second dose may be much larger than the first dose. In other words, the first dose may be a very small dose.

In some embodiments, further referring to FIG. 5 or FIG. 12 , the actuator 1050 may include a bearing portion 1051, and the bearing portion 1051 is used to abut against the delivery pipe seat 1040 to prevent the delivery pipe seat 1040 from leaving the first position. As shown in FIG. 4 or FIG. 10 , in the first position, the bearing surface of the bearing portion 1051 may abut against the end surface of the delivery pipe seat 1040 to prevent the delivery pipe seat 1040 from leaving the first position.

In some embodiments, referring to FIG. 7 , the first housing 1030 may include a first spiral portion 1031, and referring to FIG. 6 , the delivery tube seat 1040 may include a second spiral portion 1041, the spiral end surface of the second spiral portion 1041 may be matched with the spiral end surface of the first spiral portion 1031, and the first spiral portion 1031 and the second spiral portion 1041 are configured so that the delivery tube seat 1040 can be moved to the loading position when the delivery tube seat 1040 rotates relative to the first housing 1030 along the matched first spiral portion 1031 and the second spiral portion 1041. In other words, the spiral end surfaces of the first spiral portion 1031 and the second spiral portion 1041 can be combined together, for example, the high part of the spiral portion of one can be combined with the low part of the spiral portion of the other, and the two can achieve relative rotation, and during the relative rotation process (for example, the process from FIG. 2 to FIG. 3 ), due to the spiral end surface, the second spiral portion 1041 can gradually move away from the first housing 1030, thereby gradually reaching the loading position.

In some embodiments, the first spiral portion 1031 and/or the second spiral portion 1041 are configured such that when the second spiral portion 1041 is about to be separated from the first spiral portion 1031, the delivery tube holder 1040 reaches the loading position. And the starter 1050 is configured such that when the second spiral portion 1041 is separated from the first spiral portion 1031, a portion of the delivery tube holder 1040 that will first contact the starter 1050 is spaced apart from a predetermined distance from the bearing portion 1051 of the starter 1050, and the predetermined distance is the distance that the delivery tube holder 1040 moves when it moves from the loading position toward the first housing 1030 to the first position.

For example, as shown in FIG. 3 to FIG. 4, in the position of FIG. 3, the second spiral portion 1041 is about to be separated from the first spiral portion 1031, and at this time, the delivery tube seat 1040 and the bearing portion 1051 are separated by a preset distance. Under the action of the first elastic member, the delivery tube seat 1040 will further move toward the first shell 1030 to the first position shown in FIG. 4, in which the delivery tube seat 1040 and the bearing portion 1051 are in contact with each other. The distance from the position of FIG. 3 to the position of FIG. 4 is the preset distance, which corresponds to the first dose of the pre-injected fluid. For another example, as shown in FIG. 10, when the second spiral portion 1041 is about to be separated from the first spiral portion 1031, the second spiral portion 1041 can be separated from the bearing portion 1051 by a preset distance (for example, the bearing portion 1051 is slightly lower than the highest point of the first spiral portion 1031, and the distance from the bearing portion 1051 to the highest point of the first spiral portion 1031 is the preset distance). When the second spiral portion 1041 is separated from the first spiral portion 1031 , the delivery tube seat 1040 falls back onto the bearing portion 1051 .

It will be appreciated that the preset distance may be a very small distance, such as 1 mm, 2 mm or 3 mm, relative to the moving distance of the delivery tube holder 1040 from the first position to the second position.

The disengagement of the second spiral portion 1041 from the first spiral portion 1031 means that there is no contact between the two, so that when the delivery tube seat 1040 is released, it can smoothly return to the initial position, that is, the second position.

In some embodiments, returning to FIG. 5 , the actuator 1050 may have an annular shape, and as shown in FIG. 2 , the actuator 1050 surrounds the first housing 1030 and is disposed concentrically with the first housing 1030. Furthermore, the actuator 1050 is configured to move eccentrically relative to the first housing 1030 when the delivery pipe seat 1040 rotates relative to the first housing 1030, so that when the delivery pipe seat 1040 moves to the first position, the bearing portion 1051 of the actuator 1050 can abut against the delivery pipe seat 1040.

As shown in Figures 2 and 3, when the delivery tube seat 1040 rotates relative to the first shell 1030, the starter 1050 moves eccentrically relative to the first shell 1030 (i.e., moves in the direction of arrow X in Figure 3). At this time, the annular starter 1050 that was originally concentric with the first shell 1030 is no longer concentric with the first shell 1030, so that the supporting part 1051 that originally would not abut the delivery tube seat 1040 is located on the falling path of the delivery tube seat 1040, thereby blocking the delivery tube seat 1040.

In some embodiments, the atomizer 1000 may further include a second shell 1060, which is arranged around the delivery tube holder 1040 and is configured to drive the delivery tube holder 1040 to rotate, and the second shell 1060 has a pressing portion 1061, and the pressing portion 1061 is configured to push the starter 1050 to make the starter 1050 move eccentrically relative to the first shell 1030 when the second shell 1060 drives the delivery tube holder 1040 to rotate relative to the first shell 1030.

In some embodiments, the bearing portion 1051 of the starter 1050 has a first pressing slope 1052 , and the pressing portion 1061 includes a protrusion having a second pressing slope 1062 , and the pressing portion 1061 pushes the starter 1050 through the abutment between the second pressing slope 1062 and the first pressing slope 1052 .

As shown in FIG9 , when the second housing 1060 drives the delivery tube seat 1040 to rotate relative to the first housing 1030, the pressing portion 1061 of the second housing 1060 passes the position of the bearing portion 1051 of the actuator 1050. The second pressing inclined surface 1062 on the pressing portion 1061 gradually abuts against the first pressing inclined surface 1052 of the actuator 1050, thereby gradually pushing the actuator 1050 to move in the direction indicated by the arrow X. Therefore, the actuator 1050 can be pushed to the position shown in FIG3 .

It will be understood that, as shown in FIG. 5 , the actuator 1050 may have a groove 1053 , which may be sleeved on the rib 1032 of the first housing 1030 and slidable relative to the rib 1032 , thereby orienting the movement direction of the actuator 1050 when the actuator 1050 is pushed.

In some embodiments, as shown in FIGS. 2 and 3 , the atomizer 1000 may further include a button connector 1070, which is mechanically coupled to the actuator 1050 and is used to trigger the actuator 1050 so that the actuator 1050 releases the delivery tube holder 1040. For example, by pressing the button connector 1070 in a direction opposite to the direction X, the actuator 1050 may be moved in a direction opposite to the direction X to a position concentric with the first housing 1030, so that the bearing portion 1051 no longer blocks the delivery tube holder 1040.

In some embodiments, referring to Figures 10 to 12, the starter 1050 can have the shape of a bent arm, the starter 1050 is partially arranged around the first shell 1030, the bearing portion 1051 is arranged at the first end 1054 of the bent arm and extends radially inward from the body of the starter 1050, and the starter 1050 is configured to be able to pivot relative to the first shell 1030 when the delivery tube seat 1040 rotates relative to the first shell 1030, so that when the delivery tube seat 1040 moves to the first position, the bearing portion 1051 of the starter 1050 can abut the delivery tube seat 1040.

In some embodiments, as shown in Figure 12, the atomizer 1000 may also include a button connector 1070, and the second end 1055 of the starter 1050 opposite to the first end 1054 is movably connected to the button connector 1070, and the connection portion 1056 between the first end 1054 and the second end 1055 of the starter 1050 can be pivotally connected to the first shell 1030, so that by operating the button connector 1070, the starter 1050 can be triggered to pivot around the connection portion 1056, thereby releasing the delivery tube seat 1040.

For example, in Figures 10 and 12, it can be seen that the second end 1055 is movably connected to the button connector 1070, and the connecting portion 1056 can be pivotally connected to the axis on the first shell 1030, so that when the user presses the button and then presses the button connector 1070, the second end 1055 of the launcher 1050 moves radially inward (toward the first shell 1030), so that the launcher 1050 in the shape of a bent arm rotates around its own connecting portion 1056, thereby, the first end 1054 will move radially outward (away from the first shell 1030).

In some embodiments, the first spiral portion may include two centrally symmetrical first spiral portions, the second spiral portion may include two centrally symmetrical second spiral portions, and, as shown in FIG12 , the starter 1050 may include two curved arms, one on the left and one on the right, which are partially disposed around the first housing 1030 from respective directions. When the delivery pipe seat 1040 is in the first position, the two curved arms, one on the left and one on the right, can respectively carry the two second spiral portions, thereby improving the carrying stability of the delivery pipe seat 1040.
