Embodiments of the present utility model will be described below with reference to the accompanying drawings.

The embodiment of the utility model provides an assembling device of a sprayer. Fig. 1 is a schematic view of an assembling apparatus of a sprayer according to an embodiment of the utility model. As shown in fig. 1, the assembling apparatus 100 of the atomizer includes: an end cap holding part 1, a cavity holding part 2 and a driving part 3.

The end cap holding part 1 is used for accommodating at least one part of an end cap of the sprayer; the cavity holding part 2 is used for accommodating at least a part of the cavity of the sprayer; the end cap holding portion 1 and the cavity holding portion 2 are disposed opposite to each other in the first direction so that the end cap and the cavity are coaxial; the driving part 3 drives the end cap holding part 1 and/or the cavity holding part 2 to move in the first direction.

According to the above embodiment, by making the end cap holding portion accommodate at least a part of the end cap of the atomizer, and the cavity holding portion accommodate at least a part of the cavity of the atomizer, the end cap holding portion and the cavity holding portion are disposed opposite to each other in the first direction in such a manner that the end cap and the cavity are coaxial, and the end cap holding portion and/or the end cap holding portion are driven to move in the first direction by the driving portion, the end cap and the cavity of the atomizer can be assembled, and the assembling efficiency and reliability of the atomizer can be improved.

Fig. 2 is a schematic view of an assembly device of a sprayer and an end cap and a cavity of the sprayer according to an embodiment of the utility model. As shown in fig. 2, the cap holder 1 and the cavity holder 2 of the assembly device 100 are used to hold the cap 10 and the cavity 20 of the atomizer, respectively, and in a state where the cap 10 and the cavity 20 are held in the cap holder 1 and the cavity holder 2, the cap 10 and the cavity 20 are in a coaxial positional relationship, that is, a first end portion of the cavity 20 near the cap 10 is aligned with an opening portion of the cap 10 for accommodating the first end portion, whereby, when the cap holder 1 and the cavity holder 2 are brought close to each other by the driving of the driving portion 3, the first end portion of the cavity 20 can be accurately pressed into the opening portion of the cap 10.

In some embodiments, the end cap holder 1 of the assembly device 100 may hold end caps 10 of various shapes, and the cavity holder 2 may hold cavities 20 of various shapes. The structure or shape of the end cap holding portion 1 and the cavity holding portion 2 may be adaptively designed according to the shape of the end cap 10 and the cavity 20 to be held. In order to facilitate the explanation of the structures of the end cap holding portion 1 and the cavity holding portion 2, the structures of the end cap 10 and the cavity 20 are exemplarily explained below with reference to fig. 3 to 6, respectively. It will be appreciated that the end cap 10 and cavity 20 may be of a different construction than that described below.

Fig. 3 is a schematic view of the structure of the end cap 10 according to the embodiment of the present utility model, and fig. 4 is an exploded view of the structure of the end cap 10 according to the embodiment of the present utility model. In some embodiments, as shown in fig. 3 and 4, the end cap 10 may include an end cap body portion 101, the end cap body portion 101 forming an opening 102 on a side facing the cavity 20 for receiving a first end of the cavity 20. The opening 102 may be matched to the first end of the cavity 20, e.g., the opening 102 may have an inner diameter equal to the outer diameter of the first end of the cavity 20 or slightly larger than the outer diameter of the first end of the cavity 20.

In some embodiments, as shown in fig. 3 and 4, the end cap 10 may further include a sealing portion 103, a pressing portion 104, and a fastening portion 105. The pressing portion 104 sandwiches the sealing portion 103 with the cap body 101, and the fastening portion 105 connects the pressing portion 104 and the cap body 101.

In some embodiments, as shown in fig. 3 and 4, the sealing portion 103 is located on a side of the end cap body portion 101 that is adjacent to the cavity 20. The sealing portion 103 is located on the outer peripheral side of the first end portion in a state where the first end portion of the cavity 20 is accommodated in the opening portion 102 of the end cap 10, and seals the end cap 10 and the cavity 20. The seal 103 may be various elastic members, such as a rubber seal.

In some embodiments, as shown in fig. 3 and 4, the pressing portion 104 is located at a side of the sealing portion 103 near the cavity 20, detachably connected with the cap main body portion 101 in a state of sandwiching the sealing portion 103. The sealing portion 103 can be elastically deformed in the radial direction of the sealing portion 103 under the pressing of the pressing portion 104, so that the tightness between the end cover 10 and the cavity 20 can be ensured, and the reliability of the connection between the end cover 10 and the cavity 20 can be further improved by pressing the first end portion of the cavity 20 in the radial direction by the sealing portion 103.

In some embodiments, the fastening portion 105 may be various components having a connection function. For example, as shown in fig. 3 and 4, the fastening portion 105 may be a screw or the like. The end cap 10 may further include a first ear portion 106 disposed radially outward of the end cap body portion 101 and a second ear portion 107 disposed radially outward of the pressing portion 104. The screw (fastening portion 105) is engaged with the first and second lugs 106 and 107 to connect the pressing portion 104 and the fastening portion 105, and the relative distance between the pressing portion 104 and the fastening portion 105 can be adjusted by adjusting the depth of the screw which is suspended into the through holes of the first and second lugs 106 and 107, so that the urging force of the pressing portion 104 on the seal ring 103 can be adjusted, and further, the deformation amount of the seal ring 103 can be adjusted.

For example, the depth to which the screw is suspended into the through hole is a first depth before the first end of the cavity 20 is received in the opening 102 of the end cap 10, and may be adjusted to a second depth greater than the first depth after the first end of the cavity 20 is received in the opening 102 of the end cap 10. Before the cavity 20 is pressed into the end cover 10, the screw is suspended into the through hole to a first depth which is shallower, so that the acting force of the pressing part 104 on the sealing ring 103 can be reduced, and the deformation amount of the sealing ring 103 is smaller or unchanged, thereby reducing the resistance to be overcome when the first end part of the cavity 20 is pressed into the opening part 102 of the end cover 10; after the cavity 20 is pressed into the end cap 10, the screw is suspended into the through hole to a second depth greater than the through hole, so that the force of the pressing portion 104 on the seal ring 103 can be increased, and the deformation amount of the seal ring 103 is greater, thereby ensuring the tightness and connection reliability of the end cap 10 and the cavity 20.

Fig. 5 is another schematic illustration of the structure of the end cap 10 of an embodiment of the present utility model. As shown in fig. 3-5, the end cap 10 may further include a first joint 108, the first joint 108 being located, for example, radially outward of the end cap body 101 for connecting the end cap body 101 with an external component. The end cap 10 may further comprise a second joint 109, for example at the side of the end cap body 101 remote from the cavity 20, which second joint 109 coincides with the centre axis of the end cap body 101 as seen in axial direction, for connecting the end cap body 101 with an external component.

Fig. 6 is a schematic view of the structure of the cavity 20 according to the embodiment of the present utility model. As shown in fig. 6, the cavity 20 may include a cavity body 201, and the cavity body 201 may be, for example, substantially cylindrical and hollow. The end of the cavity body 201 near the end cap 10 is a first end 202, and the end far from the end cap 10 is a second end 203. The cavity 20 may further include a first interface 204 disposed between the first end 202 and the second end 203 of the cavity body 201, for example, the first interface 204 being for delivering substances such as aerosols to external components. The cavity 20 may further comprise a second port 205 provided at the second end 203, for example, the second port 205 being adapted to drain waste liquid to external components.

Fig. 7 is a schematic view of the structure of the end cap holding portion 1 of the embodiment of the present utility model. In some embodiments, as shown in fig. 7, the end cap holder 1 may include a first bottom portion 11 and a first wall portion 12. Wherein the first wall portion 12 extends from the first bottom portion 11 towards the cavity holding portion 2, the first bottom portion 11 and the first wall portion 12 enclose a first receiving space for receiving at least a portion of the end cap 10, which first receiving space matches at least a portion of the end cap 10, e.g. the end cap holding portion 1 may be of a line-like design. Thereby, the end cap holding portion 1 can reliably hold the end cap 10; when the end cap holding portion 1 and the cavity holding portion 2 are brought close to each other, the first bottom portion 11 of the end cap holding portion 1 can limit the end cap 10 held in the end cap holding portion 1 in the first direction, so that the end cap 10 and the cavity 20 can be reliably connected.

In some embodiments, at least a portion of the end cap 10 received in the end cap holder 1 is, for example, an end of the end cap 10 remote from the cavity 20. The present utility model is not limited thereto, and for example, the end cap holding portion 1 may accommodate the entirety of the end cap 10. This can more reliably hold the end cap 10.

In some embodiments, as shown in fig. 7, the first wall portion 12 may include at least one first recess 122 disposed proximate to the first end surface 121 of the cavity-holding portion 2, the first recess 122 for receiving the first positioning portion of the end cap 10, the first recess 122 being shaped to mate with the first positioning portion. By providing the first recess 122 for accommodating the first positioning portion of the end cap 10 in the end cap holding portion 1, the positional relationship between the end cap 10 and the end cap holding portion 1 can be defined by the first positioning portion of the end cap 10, so that the end cap 10 can be ensured to be in a preset posture in the end cap holding portion 1, whereby the accuracy of assembly of the end cap 10 and the cavity 20 can be improved. Further, by matching the shape of the first concave portion 122 with the first positioning portion, for example, the cross-sectional dimension of the first concave portion 122 perpendicular to the axial direction is the same as or slightly larger than the cross-sectional dimension of the first positioning portion, whereby the end cap 10 can be held more reliably by the first concave portion 122.

In some embodiments, the first positioning portion of the end cap 10 may be various components of the end cap 10. For example, the first positioning portion may be the fastening portion 105 of the end cap 10. As shown in fig. 5, the fastening portion 105 protrudes from the first ear portion 106 in a direction away from the cavity 20. By using the fastening portion 105 as the first positioning portion, positioning can be achieved by using the original member of the end cap 10, which contributes to simplification of the structure of the end cap 10.

In some embodiments, the depth of the at least one first recess 122 may be set according to the thickness of the end cap holder 1 and the length of the first positioning portion of the end cap 10. Fig. 8 is another schematic view of the structure of the end cap holder 1 of the embodiment of the present utility model, which shows the second end surface 124 of the end cap holder 1 on the side away from the cavity holder 2. As shown in fig. 8, the first recess 122 may be a through hole. Thereby, the first concave portion 122 can be easily formed on the end cap holding portion 1. In addition, in the case where the first positioning portion of the end cap 10 is the fastening portion 105, by providing the first concave portion 122 as a through hole, the end cap holding portion 1 can be prevented from changing the depth of the fastening portion 105 in the first and second lugs 106 and 107 during the process of pressing the cavity 20 into the end cap 10, and the cavity 20 and the end cap 10 can be assembled more smoothly.

In some embodiments, the number and relative positional relationship of the at least one first recess 122 may also be matched to the first positioning portion. For example, the number of the at least one first concave portion 122 may be the same as the number of the first positioning portions of the end cap 10, and when the number of the first concave portions 122 is a plurality of the first concave portions, the relative positional relationship of the plurality of first concave portions 122 may be the same as the relative positional relationship of the plurality of first positioning portions. This enables the end cap 10 to be positioned more reliably.

In some embodiments, as shown in fig. 7, the first wall portion 12 may include at least one second recess 123 disposed at the first end surface 121, and the second recess 123 may penetrate in a thickness direction of the first wall portion 12 for receiving the first joint 108 of the end cap 10. This can prevent the end cap holder 1 from interfering with the first joint 108 of the end cap 10, and can directly insert the end cap 10 into the end cap holder 1.

In some embodiments, the assembled end cap 10 and cavity 20 need to be aligned in a prescribed manner in the circumferential direction. For example, the positional relationship of the end cap 10 and the cavity 20 in the circumferential direction is defined by the first joint 108 of the end cap 10 and the first interface 204 of the cavity 20. For example, the first joint 108 and the first interface 204 are disposed radially opposite, i.e., 180 ° apart in the circumferential direction. In this case, by providing the second recess 123 on the first wall portion 12, the position of the first joint 108 of the end cap 10 in the end cap holding portion 1 can be defined, and thus, the accuracy of assembly of the end cap 10 and the cavity 20 can be further improved.

In some embodiments, as shown in fig. 7, in the case where the first end surface 121 of the end cap holding portion 1 is provided with both the first concave portion 122 and the second concave portion 123, the first concave portion 122 may be unevenly spaced from the second concave portion 123, so that the position of the end cap 10 in the end cap holding portion 1 can be uniquely defined.

In some embodiments, as shown in fig. 7 and 8, the first bottom 11 may include a through hole 111, which may be located at the center of the first bottom 11, for receiving the second tab 109 of the end cap 10. Thereby, the second tab 109 of the end cap 10 can be prevented from interfering with the end cap holding portion 1.

Fig. 9 is a schematic view of the structure of the cavity holding part 2 according to the embodiment of the present utility model. In some embodiments, as shown in fig. 9, the cavity holding part 2 may include: a second bottom 21 and a second wall 22. Wherein the second bottom 21 may support the cavity 20 in a second direction perpendicular to the first direction. The second wall portion 22 may extend from the second bottom 21 in the second direction. Wherein the second wall portion 22 includes a sub-wall portion 221 extending in the second direction from an end of the second bottom portion 21 remote from the end cap holding portion 1, which limits the cavity 20 in the first direction. Thus, when the end cap holding portion 1 and the cavity holding portion 2 come close to each other, the sub-wall portion 221 of the cavity holding portion 2 can limit the cavity 20 held in the cavity holding portion 2 in the first direction, and thus, the end cap 10 and the cavity 20 can be reliably connected.

In some embodiments, as shown in fig. 1, the first direction may be a direction in which the end cap holder 1 and the cavity holder 2 are opposite, for example, a horizontal direction; the second direction may be a direction perpendicular to the first direction, for example, an up-down direction. The present utility model is not limited thereto, and the first direction and the second direction may be other directions perpendicular to each other.

In some embodiments, as shown in fig. 9, the second bottom 21 may be a substantially rectangular plate shape, the long side direction of which is parallel to the axial direction of the cavity main body 201 of the cavity 20. The sub-wall 221 may extend in the second direction from a short edge of the second bottom 21 away from the end cap holder 1. Further, as shown in fig. 9, the second wall portion 22 may further include a side wall portion 222 extending from the long side of the second bottom portion 21 in the second direction, whereby the cavity 20 can be restrained by the side wall portion 222 in a third direction (shown in fig. 1) perpendicular to the first direction and the second direction.

In some embodiments, as shown in fig. 9, the cavity holding part 2 may include a first opening part 23 opened in the second direction, whereby the cavity 20 can be easily put into the cavity holding part 2 or taken out of the cavity holding part 2 via the first opening part 23. The cavity holding portion may include a second opening portion 24 that is open in the first direction, whereby connection of the end cap 10 and the cavity 20 via the second opening portion 24 can be facilitated.

In some embodiments, as shown in fig. 9, the second bottom 21 may include a third recess 212 disposed at a third end surface 211 of the support cavity 20, the third recess 212 may be configured to receive the first interface 204 of the cavity 20. As described above, in the case where the assembled end cap 10 and cavity 20 need to be aligned in a predetermined positional relationship in the circumferential direction, for example, in the case where the positional relationship in the circumferential direction of the end cap 10 and cavity 20 is defined by the first joint 108 of the end cap 10 and the first interface 204 of the cavity 20, the position of the first interface 204 of the cavity 20 in the cavity holding portion 2 can be defined by providing the third recess 212 on the second bottom 21, and thus, the accuracy of the assembly of the end cap 10 and cavity 20 can be further improved.

In some embodiments, in the assembly device 100, the second recess 123 of the end cap holder 1 for receiving the first joint 108 of the end cap 10 and the third recess 212 of the cavity holder 2 for receiving the first interface 204 of the cavity 20 may be disposed radially opposite. This ensures that the end cap 10 and the cavity 20 are assembled in a predetermined positional relationship in the circumferential direction, and thus, the accuracy of assembly can be further improved. The present utility model is not limited thereto, and the second recess 123 and the third recess 212 may be provided so as to correspond to other predetermined positional relationships.

In some embodiments, as shown in fig. 9, the second bottom 21 may further include a barrier 213. The blocking portion 213 may be located at a side of the third recess 212 near the end cap holding portion 1. With the cavity 20 in the cavity holder 2, the first interface 204 of the cavity 20 at least partially coincides with the blocking portion 213, as seen in the axial direction. Thus, after the end cap holding portion 1 and the cavity holding portion 2 drive the end cap 10 and the cavity 20 to move to the assembly position and complete the assembly, the blocking portion 213 can limit the first interface 204 of the cavity 20 in the process that the end cap holding portion 1 and the cavity holding portion 2 move toward the positions away from each other, so that the cavity 20 is prevented from sliding out of the cavity holding portion 2, and the end cap 10 connected to the cavity 20 can be smoothly released from the end cap holding portion 1. This can further simplify the assembly operation and further improve the assembly efficiency.

In some embodiments, as shown in fig. 9, the cavity holding part may further include a fixing part 214 provided at the second wall part 22 to limit the cavity 20 accommodated in the cavity holding part 2 in the second direction. For example, in the case where the end cap 10 and the cavity 20 are not perfectly aligned or coaxial in the first direction, the cavity 20 is easily displaced in the second direction perpendicular to the first direction during pressing of the cavity 20 into the end cap 10. The fixing portion 214 limits the cavity 20 in the second direction, so that the reliability of assembling the end cap 10 and the cavity 20 can be further improved.

In some embodiments, where the fixing portion 214 limits the cavity 20 in the second direction, the fixing portion 214 may abut a preset portion of the cavity 20, for example, a portion of the cavity 20 closer to the end cap holding portion 1 than a midpoint in the axial direction of the cavity 20. Since the end portion of the cavity 20 near the end cap holding portion 1 (i.e., the first end portion 202) is more easily displaced if the end cap 10 and the cavity 20 are not perfectly aligned in the first direction during the pressing of the cavity 20 into the end cap 10, the cavity 20 can be more reliably restrained by abutting the fixing portion 214 with the above-described predetermined portion of the cavity 20, so that the reliability of the assembly of the end cap 10 and the cavity 20 can be further improved.

In some embodiments, the fixing portion 214 may be various structures capable of limiting the cavity 20 in the second direction. As shown in fig. 9, the fixing portion 214 may be a rotatable lever. One end 214a of the rotatable strut may be rotatably secured to the second wall 22 and the other end 214b may be movable between a first position and a second position, wherein the first and second positions may be in and out of abutment with the cavity 20, respectively. Thus, the fixing portion 214 can be realized with a simple structure. When the other end 214b of the rotatable pressing rod is located at the first position, the other end 214b abuts against the cavity 20, so that the cavity 20 can be limited in the second direction; when the other end 214b is located at the second position, the rotatable pressing lever does not interfere with the operation of putting the cavity 20 into the cavity holding portion 2 or taking it out from the cavity holding portion 2, and thus, the assembling operation can be simplified.

In some embodiments, the axis of rotation of one end 214a of the rotatable strut may be parallel to the second direction.

The present utility model is not limited thereto, and the fixing portion 214 may be another structure, for example, the fixing portion 214 may be an engaging portion protruding from the inner side of the side wall portion 222, and when the cavity 20 is accommodated in the cavity holding portion 2, the engaging portion engages with the cavity 20, whereby a force in the second direction can be applied to the cavity 20; alternatively, the fixing portion 214 may be a cover portion provided to face the bottom portion 21 in the second direction; etc.

In some embodiments, as shown in fig. 9, the second wall portion 22 may further include a fourth recess 223. The fourth recess 223 may be provided at an end surface of the second wall portion 22 remote from the second bottom portion 21. The fourth recess 223 is through which a finger of a user or a gripping means of the cavity 20 can pass, thereby facilitating the insertion of the cavity 20 into the cavity holder 2 or the removal from the cavity holder 2.

In some embodiments, the driving part 3 may be various components capable of moving the end cap holding part 1 and/or the cavity holding part 2. Fig. 10 is another schematic view of the structure of the assembly device 100 according to the embodiment of the present utility model. In some embodiments, as shown in fig. 10, the driving part 3 may include a driving cylinder 31, a driving link 32, a gas control valve 33, and a switch 34. Among them, the gas control valve 33 may be connected to the driving cylinder 31 to control the gas supply to the driving cylinder 31. A switch 34 may be connected to the gas control valve 33 for controlling the on-off of the gas control valve 33. For example, when the switch 34 controls the gas control valve 33 to be on, gas is supplied to the driving cylinder 31 via the gas control valve 33, and when the switch 34 controls the gas control valve 33 to be off, gas is not supplied to the driving cylinder 31.

Fig. 11 is a schematic view showing the structures of the driving cylinder 31 and the driving link 32 according to the embodiment of the present utility model. As shown in fig. 10 and 11, one end 32a of the driving link 32 may be connected to the driving cylinder 31, and the other end 32b may be connected to the end cap holder 1 and/or the cavity holder 2. Thus, when the driving cylinder 31 drives the driving link 32 to move, the end cap holding part 1 and/or the cavity holding part 2 can be driven to move.

In some embodiments, the drive link 32 may be connected to the end cap holder 1, or may be connected to the cavity holder 2, or to both the end cap holder 1 and the cavity holder 2. This allows the driving method of the driving unit 3 to be flexibly set.

In some embodiments, as shown in fig. 10, the assembly device 100 may further include a base plate 4, wherein the driving part 3 may be disposed on the base plate 4. In the case where the driving portion 3 drives the end cap holding portion 1, the cavity holding portion 2 may be fixed to the bottom plate 4; alternatively, in the case where the driving portion 3 drives the cavity holding portion 2, the end cap holding portion 1 may be provided on the bottom plate 4. Accordingly, the relative positions of the end cap holding portion 1 and the cavity holding portion 2 can be set with reference to the bottom plate 4, which contributes to an improvement in the accuracy of the relative positions of the end cap holding portion 1 and the cavity holding portion 2.

In some embodiments, as shown in FIG. 10, the switch 34 may be a variety of switches capable of controlling on and off. For example, the switch 34 may include a first switch 341 and a second switch 342 connected in series. The gas control valve 33 is turned on in a case where both the first switch 341 and the second switch 342 are closed, wherein a distance between the first switch 341 and the second switch 342 may be greater than a preset threshold. By setting the distance between the first switch 341 and the second switch 342 to be greater than a preset threshold, the user needs to control the first switch 341 and the second switch 342 with two hands, respectively, to turn on the first switch 341 and the second switch 342 at the same time. Thus, accidental conduction of the gas control valve 33 due to erroneous operation can be avoided, and thus, safety of the assembly operation can be ensured. For example, as shown in fig. 10, the first switch 341 and the second switch 342 may be located at both ends of the bottom plate 4.

In some embodiments, as shown in fig. 10, the driving part 3 may further include a main feeding valve 35, and the main feeding valve 35 may be connected to the gas control valve 33, and the main feeding valve 35 supplies gas to the driving cylinder 31 in case that the gas control valve 33 is turned on.

In some embodiments, the driving part 3 may further include a third switch (not shown). The third switch may be connected to the driving cylinder 31 for adjusting the air pressure of the driving cylinder. Thereby, the operating pressure of the driving cylinder 31 can be set as required, so that the thrust force and the driving speed of the driving cylinder 31 can be adjusted to appropriate values.

In some embodiments, the drive cylinder 31 may be a reciprocating cylinder. For example, when the switch 34 is turned on, the driving cylinder 31 moves the end cap holder 1 and/or the cavity holder 2 from the initial position to the assembled position in a manner close to each other, and when the switch 34 is turned off, the driving cylinder 31 moves the end cap holder 1 and/or the cavity holder 2 from the assembled position to the initial position in a manner away from each other. The present utility model is not limited thereto, and the driving cylinder 31 may be another cylinder.

The driving unit 3 may have another structure. For example, the driving part 3 may include a timer connected to the driving cylinder 31, the driving cylinder 31 driving the end cap holding part 1 and/or the cavity holding part 2 to move close to each other to the assembly position in a first timing interval of the timer, and the driving cylinder 31 holding the end cap holding part 1 and/or the cavity holding part 2 in the assembly position in a second timing interval of the timer; at the third timing zone of the timer, the driving cylinder 31 drives the end cap holder 1 and/or the cavity holder 2 to move away from each other to the initial position. The reliability of the assembly can be further improved by the control of the timer.

According to the above embodiment, at least a part of the end cap of the atomizer is accommodated by the end cap holding portion, at least a part of the cavity of the atomizer is accommodated by the cavity holding portion, the end cap holding portion and the cavity holding portion are disposed opposite to each other in the first direction in such a manner that the end cap and the cavity are coaxial, and the end cap holding portion and/or the end cap holding portion are driven to move in the first direction by the driving portion, whereby the end cap and the cavity can be assembled, and the assembling efficiency and reliability of the atomizer can be improved.
