Description

Spray device Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a spray device. Background Art

[0002] A spray device is a structure that can atomize and spray liquid. When used for drug atomization, it can spray the drug into mist-like particles, which enter the lower respiratory tract directly with the patient's natural breathing, achieving the purpose of anti-inflammatory, expectorant, and antiasthmatic.

[0003] The patent with publication number US8733341B2 and patent name Atomizer with nozzle flushing mechanism and method for atomizing fluid provides an atomizer. As shown in Figure 1, the atomizer 1a mainly includes a replaceable container 3a, a retaining member 6a, a drive spring 7a, a locking element 8a, a delivery tube 9a, a pressure chamber 11a, a nozzle 12a, an upper shell 16a, a rotating member 17a, a shell part 18a and a button. The atomizer 1a includes two stages during use: triggering liquid suction and triggering spraying. To trigger aspiration, the user rotates housing portion 18a, which in turn rotates rotating member 17a, which in turn rotates holder 6a and delivery tube 9a. At this point, due to the engagement of the sliding surfaces between holder 6a and upper housing 16a, holder 6a rotates and moves downward relative to upper housing 16a, thereby allowing delivery tube 9a to draw liquid from container 3a. When holder 6a moves downward to its lower limit, the sliding surfaces between holder 6a and upper housing 16a separate. Simultaneously, a protrusion on rotating member 17a pushes locking element 8a between upper housing 16a and holder 6a, locking holder 6a in its lower limit. To trigger spraying, the user presses the button, causing locking element 8a to disengage from between upper housing 16a and holder 6a. Under the upward force of drive spring 7a, holder 6a returns delivery tube 9a to its original position, completing spraying. In this solution, since there are tolerances among the upper shell 16a, the locking element 8a and the holder 6a, when the holder 6a moves downward to the lower limit position, the locking element 8a is not easy to be stuck between the upper shell 16a and the holder 6a. In order to solve this problem, it is usually necessary to set the lower limit position of the holder 6a to be excessive. In this way, when the holder 6a moves downward to the lower limit position, the distance between the upper shell 16a and the holder 6a is sufficient for the locking element 8a to be stuck. Moreover, when the locking element 8a is stuck between the upper shell 16a and the holder 6a, under the upward force of the driving spring 7a, the holder 6a moves upward for a certain distance until it contacts the locking element 8a and stops. At this time, due to the upward movement of the holder 6a, the atomizer 1a can spray out a small amount of liquid, which serves to clean the nozzle 12a.

[0004] However, in the above solution provided by US8733341B2, since the cleaning operation of the nozzle 12a is performed after the liquid aspiration is completed, at this time, the liquid sucked from the container 3a by the delivery pipe 9a has been stored in the pressure chamber 11a. Before the nozzle 12a is cleaned, the microorganisms breeding in the nozzle 12a may have contaminated the liquid stored in the pressure chamber 11a, which is prone to health and safety problems. Summary of the Invention

[0051] 1. The present invention provides a spray device. By providing a guide member, the spray device enables the mounting member to sequentially move the liquid storage member in a first direction, a second direction, and the first direction during the entire liquid aspiration process. The second-direction movement causes the spray assembly to spray a small amount of misted liquid, thereby pre-cleaning the nozzle. Liquid aspiration then continues until liquid aspiration is complete. In other words, the spray device sequentially undergoes three steps during the entire liquid aspiration process: a small amount of liquid aspiration, a small amount of spraying, and completion of liquid aspiration, first pre-cleaning the nozzle and then completing liquid aspiration.

[0052] 2. In the prior art, the nozzle is cleaned after the liquid is absorbed. In the present invention, before the liquid is finally absorbed, a small amount of liquid is absorbed and a small amount of spray is used to clean the nozzle. This can prevent microorganisms that may grow at the nozzle from contaminating the liquid in the pressure chamber, thereby ensuring the hygienic safety of the spray.

[0075] The “upper” and “lower” mentioned in the present invention are based on the markings in FIG. 2 .

[0076] The spray device of the present invention will be described in detail below with reference to FIG. 2 to FIG. 16 .

[0077] In this embodiment, as shown in Figures 2 and 3, a spray device 100 includes a spray assembly 1, a liquid reservoir 2, an actuator assembly, and a second elastic member 9. The actuator assembly includes a mounting member 3, an actuator 4, and a guide member 5. The liquid reservoir 2 is used to hold liquid. The spray assembly 1 includes an infusion element 11, a nozzle 12, a pressure chamber 13, and a pump body 14. The nozzle 12 is located at one end of the pump body 14, and the pressure chamber 13 is located within the end of the pump body 14 connected to the nozzle 12. One end of the infusion element 11 is inserted into the pump body 14, and the other end passes through the mounting member 3 and is inserted into the liquid reservoir 2. The infusion element 11 is used to draw liquid from the liquid reservoir 2 into the pressure chamber 13 for temporary storage, and the nozzle 12 is used to spray the liquid stored in the pressure chamber 13 in the form of a mist. The infusion element 11 is connected to the mounting member 3, which is movably connected to the actuator 4. The guide member 5 is used to guide the movement of the mounting member 3 relative to the actuator 4. Here, the infusion element 11 may be an infusion tube or other structural components that can be used to absorb liquid.

[0078] During use, the spray device 100 includes two separate processes: aspiration and spraying. The user can trigger the infusion element 11 to aspirate liquid from the liquid reservoir 2 by rotating the actuator 4. Of course, the rotation of the actuator 4 is not limited to manual operation. A drive device can also be provided within the spray device 100 to automatically drive the actuator 4 to rotate.

[0079] Specifically, when the liquid suction is triggered, the actuator 4 drives the mounting member 3 to rotate, and under the guidance of the guide member 5, the mounting member 3 can move relative to the actuator 4 in the first direction. In this way, the infusion element 11 is driven to move along the first direction by the mounting member 3, so that the infusion element 11 absorbs the liquid.

[0080] During the process of triggering liquid aspiration, when the mounting member 3 moves in the first direction to a preset position, the mounting member 3, guided by the guide member 5, moves in a second direction, which is opposite to the first direction. Thus, the mounting member 3 drives the infusion element 11 to move in the second direction, triggering the spray assembly 1 to spray a small amount of mist-like liquid, thereby pre-cleaning the nozzle 12. Then, the actuator 4 continues to rotate, and under the guidance of the guide member 5, the mounting member 3 drives the infusion element 11 to move in the first direction. The infusion element 11 continues to aspirate liquid from the liquid reservoir 2 and transfers it to the pressure chamber 13. When the mounting member 3 drives the infusion element 11 to the fully aspirated position, the spray device 100 completes the entire liquid aspiration process. The second elastic member 9 is sleeved on the outer periphery of the liquid reservoir 2 and is compressed during the movement of the mounting member 3 in the first direction.

[0081] When the spray is continuously triggered, the second elastic member 9 rebounds, so that the mounting member 3 drives the infusion element 11 to move along the second direction, thereby achieving quantitative spraying.

[0082] By adopting the above technical solution and setting the guide member 5, the spray device 100 can, during the entire liquid absorption process, have the mounting member 3 drive the infusion element 11 to move in the first direction, the second direction, and the first direction in sequence. The second direction movement occurring in this stage causes the spray assembly 1 to spray a small amount of mist liquid, thereby pre-cleaning the nozzle 12, and then continuing the liquid absorption operation until the liquid absorption is completed. That is, during the entire liquid absorption process, the spray device 100 sequentially undergoes three processes: a small amount of liquid absorption, a small amount of spraying, and completion of liquid absorption. The nozzle 12 is pre-cleaned first, and then the liquid absorption is completed. In this way, compared to the prior art solution of cleaning the nozzle 12 when the liquid absorption is completed, this solution can prevent the microorganisms that may breed in the nozzle 12 from contaminating the liquid that is ultimately transmitted to the pressure chamber 13 through the infusion element 11, thereby ensuring the hygienic safety of the spray. In addition, the overall structural changes of the spray device 100 are small, which is conducive to cost control.

[0083] Of course, the reset structure of the mounting member 3 is not limited to the second elastic member 9 , and may also be other structures or mechanisms that can provide reset.

[0084] In one embodiment, the liquid storage member 2 is connected to the mounting member 3, so that the infusion element 11, the liquid storage member 2 and the mounting member 3 can move synchronously.

[0085] In one embodiment, as shown in Figure 2, the downward movement direction of the mounting member 3 is the first direction, and the upward movement direction is the second direction. Of course, the movement direction of the mounting member 3 is not limited to this, and can also be moved in other directions such as the east-west direction.

[0086] In one embodiment, as shown in FIG. 4 and FIG. 7 , the mounting member 3 is provided with a slope 31 , and the guide member 5 includes a guide structure 51 , and the guide structure 51 includes a first guide slope 511 and a second guide slope 512 .

[0087] When the actuator 4 is rotated to trigger liquid aspiration, the actuator 4 drives the mounting member 3 to rotate, and under the matching of the slope 31 and the first guide slope 511, the slope 31 slides along the first guide slope 511. In this way, the mounting member 3 can move relative to the actuator 4 in the first direction while rotating along with the actuator 4. The infusion element 11 is driven by the mounting member 3 to move in the first direction, so that the infusion element 11 can aspirate liquid.

[0088] When the slope 31 moves to disengage from the first guide slope 511, the mounting member 3 moves in the second direction so that the slope 31 moves to cooperate with the second guide slope 512. At this time, the mounting member 3 drives the infusion element 11 to move in the second direction to trigger the spray assembly 1 to spray to clean the nozzle 12.

[0089] Then, the actuator 4 continues to rotate, and with the cooperation of the slope 31 and the second guide slope 512, the slope 31 slides along the second guide slope 512. In this way, the mounting member 3 drives the infusion element 11 to move along the first direction to the complete liquid aspiration position, so that the spray device 100 completes the liquid aspiration.

[0090] In the above embodiment, the guide member 5 provides the first and second guide slopes 511, 512, and defines the positional relationship between these two guide slopes. Furthermore, the mounting member 3 provides the slope 31 and defines the coordination relationship between the slope 31 and the first and second guide slopes 511, 512, respectively. This allows the spray device 100 to sequentially undergo three stages during the entire liquid aspiration process: small amount of liquid aspiration, small amount of spraying, and complete liquid aspiration. In this embodiment, the guide member 5 has a simple structure, requiring minimal structural changes to the mounting member 3. Furthermore, the spray device 100 can pre-clean the nozzle 12.

[0091] Furthermore, as shown in Figures 4 and 6, the guide structure 51 includes a connecting surface 513, which extends from the end of the first guide slope 511 along the second direction to the head end of the second guide slope 512. In this way, during the liquid absorption process, when the slope 31 moves to separate from the first guide slope 511, the mounting member 3 needs to move along the second direction so that the slope 31 moves to cooperate with the second guide slope 512, thereby achieving pre-cleaning.

[0092] Of course, the pre-cleaning function can be achieved twice or even more times by changing the number of guiding inclined surfaces of the guiding structure 51 to improve the pre-cleaning strength.

[0093] Of course, the structure of the guide member 5 is not limited to this, and may also be any other structure capable of guiding the mounting member 3 to drive the infusion element 11 to move in the first direction, the second direction, and the first direction in sequence throughout the aspiration process. Of course, the above-mentioned function can also be achieved by limiting the number and location of the guide members 5. For example, two guide members 5 may be provided, and through the structure and / or location of the two guide members 5, the mounting member 3 can be guided to drive the infusion element 11 to move in the first direction, the second direction, and the first direction in sequence throughout the aspiration process.

[0094] In one embodiment, as shown in FIG7 , the mounting member 3 includes a first flat surface 32 connected to the ramp surface 31. As shown in FIG4 and FIG6 , the guide structure 51 includes a second flat surface 514 connected to the second guide ramp surface 512. When the mounting member 3 drives the infusion element 11 to the fully aspirated position, the ramp surface 31 disengages from the second guide ramp surface 512, and the first flat surface 32 and the second flat surface 514 abut against each other in the axial direction. The surface-to-surface fit between the mounting member 3 and the guide member 5 transitions from a fit between two ramps to a fit between two flat surfaces. In this way, the guide member 5 prevents the mounting member 3 from driving the infusion element 11 back to its original position and triggering the spray, allowing the user to trigger the spray again when ready.

[0095] Furthermore, as shown in Figures 2 to 4 and 7, the spray device 100 includes a spray trigger 6. When the spray is triggered, the spray trigger 6 moves under the pressure of an external force, and the spray trigger 6 pushes the guide member 5 to rotate a certain angle so that the first plane 32 can be separated from the second plane 514. Then, under the rebound force of the second elastic member 9, the mounting member 3 can be reset. When the liquid absorption is triggered, in the initial stage of the liquid absorption, the rotating mounting member 3 pushes the first guide inclined surface 511 of the guide member 5 through the slope 31 provided thereon, so that the guide member 5 rotates in the opposite direction. The guide member 5 pushes the spray trigger 6 to reset by rotating in the opposite direction. By providing the spray trigger 6, the user can operate the triggering operation of the spray, and the spray triggering operation is realized by the cooperation between the spray trigger 6 and the guide member 5, and the overall structure is simple.

[0096] Furthermore, as shown in Figures 4 to 6 , there are two guide structures 51, and the two guide structures 51 are rotationally symmetrical about the central axis of the guide member 5. Thus, when the spray trigger 6 pushes the guide member 5 to allow the first flat surface 32 to disengage from the second flat surface 514 of the first guide structure 51, the mounting member 3, under the rebound of the second elastic member 9, quickly moves in the second direction to mate with the second guide structure 51, ready for the next aspiration trigger.

[0097] In one embodiment, as shown in Figures 2, 3, and 13, the spray device 100 includes a first housing 71 having a hollow protrusion 712. The guide member 5 is rotatably mounted on the outer periphery of the hollow protrusion 712. The guide member 5 can rotate relative to the hollow protrusion 712 by a certain angle under external force. The hollow protrusion 712 is mounted on the outer periphery of the spray assembly 1. The spray assembly 1 and the guide member 5 are fixed by the first housing 71, making assembly simple.

[0098] In one embodiment, as shown in Figures 4 and 14, the first housing 71 is provided with a first protrusion 711, and the guide member 5 is provided with a first groove 52, with the first protrusion 711 axially inserted into the first groove 52. The first protrusion 711 cooperates with the first groove 52, and the circumferential dimension of the first groove 52 is limited to be larger than the circumferential dimension of the first protrusion 711, thereby limiting the rotation angle of the guide member 5. This facilitates the cooperation between the guide member 5 and the spray trigger 6 to control the rotation angle of the first plane 32 when it separates from the second plane 514, and to control the movement distance of the spray trigger 6 when it resets, so that the spray trigger 6 can accurately return to its initial position.

[0099] Of course, the structure for limiting the rotation angle of the guide member 5 is not limited to the structural features of the first protrusion 711 and the first groove 52, but also includes but is not limited to a magnetic limiting structure or a limiting structure of a telescopic lock pin.

[0100] In one embodiment, as shown in FIG. 4 , FIG. 5 , FIG. 9 and FIG. 10 , the guide member 5 has a first extension portion 53 , the first extension portion 53 has a third guide slope 531 , and the spray trigger 6 has a fourth guide slope 61 and a recessed portion 62 .

[0101] When the spray trigger 6 is pressed to trigger the spray, it moves toward the guide member 5, causing the fourth guide slope 61 provided thereon to push the third guide slope 531, causing the third guide slope 531 to slide along the fourth guide slope 61. In this way, the spray trigger 6 pushes the guide member 5 to rotate a certain angle, allowing the first flat surface 32 to disengage from the second flat surface 514, allowing the mounting member 3 to reposition the infusion element 11, triggering the spray. Furthermore, as the fourth guide slope 61 pushes the third guide slope 531, the first extension 53 of the guide member 5 inserts into the clearance recess 62, making way for the movement of the spray trigger 6.

[0102] When the actuator 4 is rotated to trigger liquid aspiration, the actuator 4 drives the mounting member 3 to rotate. The slope 31 of the mounting member 3 pushes the first guide slope 511 of the guide member 5, causing the guide member 5 to rotate in the opposite direction. At this time, the third guide slope 531 of the guide member 5 pushes the fourth guide slope 61, thereby resetting the spray trigger 6. Furthermore, as the third guide slope 531 pushes the fourth guide slope 61, the first extension 53 moves away from the recessed portion 62 due to the resetting of the spray trigger 6.

[0103] In one embodiment, as shown in FIG. 3 and FIG. 15 , the first housing 71 is provided with an opening 713 , and the spray trigger 6 is inserted into the opening 713 to facilitate assembly of the spray trigger 6 .

[0104] Furthermore, as shown in Figures 3, 9, and 15, the opening 713 is provided with a first limiting protrusion 7131, and the spray trigger 6 is provided with a limiting groove 63. The first limiting protrusion 7131 is inserted into the limiting groove 63 to limit the movement direction of the spray trigger 6. Of course, in order to improve the stability of the limiting of the spray trigger 6, the first limiting protrusion 7131 and the limiting groove 63 can be matched in two, three, or even more pairs. The multiple first limiting protrusions 7131 can be evenly distributed along the contour of the opening 713, or can be respectively located on two opposite side walls of the opening 713. Of course, the sizes of the multiple first limiting protrusions 7131 can be the same or different.

[0105] Furthermore, as shown in Figures 3 and 9, the spray trigger 6 is provided with a snap-fit ​​portion 64 that engages with the inner surface of the opening 713 to prevent the spray trigger 6 from being disengaged from the opening 713. Specifically, two opposing side walls of the spray trigger 6 are bent outward to form the snap-fit ​​portions 64, which are simple in structure and easy to manufacture. When the spray trigger 6 returns to its initial position, the snap-fit ​​portions 64 snap onto the inner surface of the opening 713 to stop the spray trigger 6.

[0106] In one embodiment, as shown in Figure 2, when the spray device 100 is in its initial state, the guide member 5 abuts the mounting member 3 in a first direction, and the guide member 5 abuts a component of the spray assembly 1 that does not move in the first or second directions in a second direction. This arrangement facilitates a compact design of the overall structure while implementing the guide member 5. The component of the spray assembly 1 that does not move in the first or second directions may be the outer housing or pump body 14 of the spray assembly 1, but does not include the infusion element 11. Preferably, when the spray device 100 is in its initial state, the guide member 5 abuts the end of the pump body 14 facing away from the nozzle 12.

[0107] In the above embodiment, the factors affecting the initial position of the mounting member 3 are the guide member 5 and the pump body 14, the factor affecting the full liquid absorption position of the mounting member 3 is the guide member 5, the factor affecting the position of the infusion element 11 is the pump body 14, and the factor affecting the position of the pump body 14 is the first shell 71. Since the factor affecting the spray metering of the spray device 100 is the relative position relationship between the mounting member 3 and the infusion element 11, and since the mounting member 3, the guide member 5 and the pump body 14 offset each other in sequence, the change in the size of the first shell 71 has a synchronous effect on the mounting member 3 and the pump body 14, that is, the change in the size of the first shell 71 will not affect the relative position relationship between the mounting member 3 and the infusion element 11. Therefore, in this embodiment, the processing dimensions of the three components, the guide member 5, the pump body 14 and the mounting member 3, will affect the accuracy of the spray metering. In the prior art shown in FIG1 , since the retaining member 6a (equivalent to the mounting member 3 ) abuts against the upper housing 16a when the atomizer 1a is in its initial state, the initial position of the retaining member 6a is influenced by the upper housing 16a (equivalent to the first housing 71 ), the fully aspirated position of the retaining member 6a is influenced by the locking element 8a and the upper housing 16a , the position of the delivery tube 9a is influenced by the pressure generator 5a (equivalent to the pump body 14 ), and the position of the pressure generator 5a is influenced by the upper housing 16a . Therefore, in the prior art, the machining dimensions of the four components—the locking element 8a, the upper housing 16a, the pressure generator 5a, and the retaining member 6a—affect the accuracy of the spray metering. Compared to the prior art, this embodiment avoids the influence of the machining accuracy of the first housing 71 on the metering accuracy, thereby reducing the machining accuracy requirements for the first housing 71 .

[0108] Furthermore, as shown in Figures 2 and 4 , the guide member 5 includes a first annular portion 54 and a second annular portion 55. One end of the second annular portion 55 is at least partially positioned opposite the hollow area of ​​the first annular portion 54. The first annular portion 54 extends along a first direction to form a second extension 541. The first guide slope 511, the second guide slope 512, the connecting surface 513, and the second flat surface 514 are all disposed on the second extension 541. When the spray device 100 is in an initial state, the spray assembly 1 is partially inserted into the first annular portion 54 and abuts one end of the second annular portion 55, and the mounting member 3 abuts the other end of the second annular portion 55.

[0109] Furthermore, as shown in Figures 2 and 7 , the mounting member 3 is provided with a first insertion groove 33, into which the guide member 5 is partially inserted, thereby facilitating the miniaturization of the overall structure of the spray device 100. The first insertion groove 33 is provided with an abutment boss 331, and when the spray device 100 is in the initial state, one end of the second annular portion 55 abuts against the abutment boss 331.

[0110] Furthermore, as shown in FIG7 , a protrusion 332 is provided in the first plug-in slot 33, and the slope 31 and the first plane 32 are provided on the protrusion 332. In this way, when the spray device 100 is in the initial state, the guide member 5 can be more accommodated in the first plug-in slot 33, which is further conducive to the miniaturization of the overall structure of the spray device 100.

[0111] In one embodiment, as shown in Figures 2 and 8 , the mounting member 3 is provided with a second insertion slot 34 , into which one end of the liquid storage member 2 is inserted, resulting in a simple and convenient assembly structure. The mounting member 3 and the liquid storage member 2 can be assembled by, but are not limited to, snap-fitting, buckling, or threading.

[0112] In one embodiment, as shown in Figures 7, 8 and 12, the outer wall of the mounting member 3 is provided with a slot 35 extending in the axial direction, and the inner wall of the actuator 4 is provided with a snap-in protrusion 41, which is movably snap-into the slot 35. In this way, when the actuator 4 drives the mounting member 3 to rotate or when the mounting member 3 is reset, the mounting member 3 can move along the extension direction of the slot 35, that is, move in the first direction or the second direction.

[0113] In one embodiment, as shown in FIG. 2 , FIG. 3 and FIG. 11 , the spray assembly 1 includes a locking mechanism 8 for locking the mounting member 3 when the mounting member 3 moves to the full liquid aspiration position.

[0114] Furthermore, as shown in Figures 2, 10 and 12, the locking mechanism 8 includes a limit block 81 and a first elastic member 82. When the spray device 100 is in the initial state, the limit block 81 abuts against one end of the mounting member 3 facing the second direction under the elastic force of the first elastic member 82. When the liquid suction is triggered, the mounting member 3 moves in the first direction, that is, in the direction away from the limit block 81. At this time, the limit block 81 can move synchronously in the first direction under the elastic force of the first elastic member 82. When the mounting member 3 moves to the full liquid suction position, the actuator 4 is limited to the limit block 81, and the mounting member 3 is locked by locking the actuator 4, thereby preventing the user from accidentally triggering the spray by rotating the actuator 4. In the prior art shown in FIG1 , when the atomizer 1a completes aspiration, the locking element 8a locks the retaining member 6a. In this solution, if the user increases the force to rotate the upper housing 16a, the upper housing 16a drives the rotating member 17a to rotate. The protrusion provided on the rotating member 17a pushes the locking element 8a during the rotation process, causing the locking element 8a to unlock and accidentally trigger the spray. In this embodiment, the locking mechanism 8 locks the actuator 4 instead of locking the mounting member 3. This prevents the user from manually rotating the actuator 4 and accidentally triggering the spray after the spray device 100 completes aspiration.

[0115] In one embodiment, as shown in Figures 10 and 12 , the stopper 81 includes a first stopper 811, and the actuator 4 includes a second stopper 42. When the mounting member 3 moves to the fully aspirated position, the first stopper 811 and the second stopper 42 engage, restricting the actuator 4 from rotating the mounting member 3. When the spray is triggered, the mounting member 3 pushes the stopper 81 in the second direction, disengaging the second stopper 42 and unlocking the stopper 81.

[0116] Furthermore, as shown in Figure 10, there are two second limiting portions 42. When the spray device 100 is in the initial state, the first limiting portion 811 and the first second limiting portion 42 are axially opposite to each other. When the mounting member 3 moves to the full liquid aspiration position, the first limiting portion 811 and the second second limiting portion 42 are engaged, and the engagement between the two limits the actuator 4 from driving the mounting member 3 to rotate. When the spray is triggered, the mounting member 3 pushes the limiting block 81 to move in the second direction, and the limiting block 81 disengages from the second limiting portion 42 to achieve unlocking. At this time, the first limiting portion 811 and the first second limiting portion 42 are axially opposite to each other. Preferably, in order to facilitate the design of the rotation angle of the actuator 4, the two second limiting portions 42 are evenly distributed along the circumference of the actuator 4. Of course, the number of second limiting portions 42 is not limited to two, and can also be three, four, or even more.

[0117] In one embodiment, as shown in FIG12 , when the spray device 100 is in an initial state, the first end surface 43 of the actuator 4 is axially opposed to the first limiting portion 811. When liquid aspiration is triggered, the limiting block 81 moves along the first direction until the first limiting portion 811 abuts the first end surface 43 and stops. The mounting member 3 continues to move along the first direction to the fully aspirated position. At this point, the actuator 4 rotates until the second limiting portion 42 is axially opposed to the first limiting portion 811. The limiting block 81 moves along the first direction under the elastic force of the first elastic member 82, causing the first limiting portion 811 to engage with the second limiting portion 42.

[0118] In the prior art shown in FIG1 , locking is achieved by engaging a locking element 8a between the upper housing 16a and the retaining member 6a. This eccentric pressing force exerted by the locking element 8a on the retaining member 6a causes the return force exerted by the drive spring 7a on the retaining member 6a to deviate from its axis when the spray is triggered by pressing the button. This eccentric impact force can easily damage the sealing ring within the pressure generator 5a. Furthermore, this eccentric impact force can easily cause friction between the delivery tube 9a and the inner wall of the pressure chamber 11a, resulting in the generation of plastic shavings and blockage. In contrast, in this embodiment, when the locking structure 8 locks the actuator 4, the locking structure 8 does not contact the mounting member 3. Consequently, when the spray is triggered by the spray trigger 6, the return force exerted by the second elastic member 9 on the mounting member 3 is unlikely to deviate from its central axis, thereby preventing damage to the sealing ring within the pressure chamber 13 and the generation of plastic shavings that could cause blockage.

[0119] In addition, in the prior art as shown in FIG1 , due to tolerances in the processing of the upper shell 16a, the locking element 8a and the retaining member 6a, the lower limit position of the retaining member 6a is set to an excessive value, which causes the sprayer 1a to easily produce the sound of parts colliding during the shaking process. Compared with the prior art, in this embodiment, only the tolerances of the first limit portion 811 and the second limit portion 42 are related to the realization of the locking function, and the assembly and cooperation between the various components are tighter, reducing or avoiding the noise caused by parts colliding and affecting the user experience.

[0120] In one embodiment, as shown in Figures 10 and 12, the first limiting portion 811 is a limiting rib structure, and the second limiting portion 42 is a limiting groove structure. The limiting ribs and the limiting grooves engage to restrict the rotation of the actuator 4. Preferably, to improve the stability of the limiting, the first limiting portion 811 can be provided with two, three, or even more limiting ribs, and the limiting grooves provided in the second limiting portion 42 match the limiting ribs of the first limiting portion 811 one by one.

[0121] In one embodiment, as shown in Figures 2 and 13, the inner wall of the first shell 71 is provided with a guide groove 714 extending axially, and the limit block 81 is axially movably engaged with the guide groove 714. The guide groove 714 limits the limit block 81 to only axial movement but not circumferential movement.

[0122] The guide groove 714 can be provided as one or more guide grooves. In order to stabilize the guiding effect of the first housing 71 on the limit block 81 while simplifying the overall structure of the spray device 100, the number of guide grooves 714 is two. In a specific embodiment, as shown in FIG10 , the limit block 81 includes a first block 813 and a second block 814 sequentially distributed along the first moving direction, and the first limit portion 811 is located on the second block 814. As shown in FIG13 , the inner wall of the first housing 71 is provided with two second limit protrusions 716, which constitute a first guide groove 7141 for guiding the movement of the first block 813; the first housing 71 is provided with an inner recess, which constitutes a second guide groove 7142 for guiding the movement of the second block 814.

[0123] Furthermore, as shown in Figures 2, 12 and 13, the inner wall of the first shell 71 is provided with a first limiting column 715; the limiting block 81 is provided with a mounting hole 812, which is provided with a second limiting column 8121; the first elastic member 82 is located in the mounting hole 812, and its two ends are respectively sleeved on the first limiting column 715 and the second limiting column 8121, which is conducive to reducing the overall size of the locking mechanism 8 and the first elastic member 82 is easy to assemble.

[0124] In one embodiment, the first elastic member 82 and the second elastic member 9 are both springs, which have a simple structure and are easy to assemble.

[0125] In one embodiment, as shown in FIG. 2 , the actuating member 4 is rotatably connected to the first housing 71 . Assembling the actuating member 4 to the first housing 71 is beneficial for simplifying the assembly structure.

[0126] Furthermore, as shown in FIG2 , the spray device 100 includes a second housing 72, which together with the first housing 71 forms the housing structure of the spray device 100, thereby enhancing the aesthetic appearance of the spray device 100. The second housing 72 is detachably connected to the actuator 4. When liquid aspiration is triggered, the user rotates the second housing 72, which in turn drives the actuator 4 to rotate. When the spray device 100 has been used a predetermined number of times, the second housing 72 can be removed and the liquid storage element 2 replaced to extend the service life of the spray device 100. Of course, the second housing 72 can also be non-detachably connected to the actuator 4, so that when the spray device 100 has been used a predetermined number of times, a new spray device 100 needs to be replaced.

[0127] It should be understood that "complete liquid aspiration" as used herein refers to the state of the spray device 100 when the spray device 100 completes a metered liquid aspiration. The "complete liquid aspiration position" as used herein refers to the current position of each movable component when the spray device 100 completes a metered liquid aspiration. For example, the complete liquid aspiration position of the mounting member 3 refers to the current position of the mounting member 3 when the spray device 100 completes a metered liquid aspiration, and the complete liquid aspiration position of the infusion element 11 refers to the current position of the infusion element 11 when the spray device 100 completes a metered liquid aspiration.

[0128] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present invention that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present invention and do not limit the scope of protection of the patent of this invention.
