As shown in fig. 1-5, the atomizing head 1 includes a housing 11, an atomizing sheet 12 (e.g., an ultrasonic microporous atomizing sheet), and a liquid guiding structure 13. The housing 1 has a shell-like structure with both upper and lower ends open (or with openings), and the atomizing sheet 12 is located inside the housing 11. The liquid guiding structure 13 is located below the atomizing sheet 12, the liquid guiding structure 13 includes a water absorbing column 131 made of a water absorbing material and a supporting member 132 for supporting the water absorbing column 131, the supporting member 132 is in a stepped cylindrical structure, and a hollow hole for filling the water absorbing column 131 is formed in the center of the supporting member 132. The upper section of the supporting member 132 has a larger outer wall diameter so as to be fixed on the inner wall of the housing 11 through an elastic buckle structure, and after the supporting member 132 is fixed, the upper end of the water absorbing column 131 is abutted against the atomizing sheet 12; the lower section of the support 132 (the lower part thereof) extends out from the lower end of the housing 11 and, in use, into the interior of the reservoir 2, while the side wall and/or bottom wall of the lower section of the support 132 is provided with liquid inlet openings.
The liquid storage bottle 2 includes a bottle body 21, a through hole 22 is formed on the top surface of the bottle body 21 for the lower part of the liquid guiding structure 13 to penetrate into, and usually before use, a sealing tin foil (not shown in the figure) or a sealing cover (not shown in the figure) is adhered to the top surface of the liquid storage bottle 2.
In this embodiment, in order to prevent the liquid storage bottle 2 from being reused, as shown in fig. 6 to 15, the following structure is designed:
first, an annular tip groove 210 is formed at the top of the bottle body 21, and a snap ring 23 is disposed in the tip groove 210 such that the snap ring 23 can rotate in the tip groove 210.
The upper end surface of the snap ring 23 is circumferentially provided with primary convex teeth 24 and multiplexing convex teeth 25 at intervals, the lower end surface is provided with positioning convex teeth 26, and correspondingly, the bottom of the top end groove 210 is circumferentially provided with three positioning grooves 27 which are matched with the positioning convex teeth 26 at even intervals.
Next, the lower end inner wall of the housing 11 is configured to be matched with the upper end outer wall of the bottle body 21, typically, a step is provided on the upper end outer wall of the bottle body 21, and the lower end inner wall of the housing 11 is in clearance fit with the circumferential outer wall of the step, and supports the housing 11 through the bottom surface of the step. Meanwhile, the inner wall of the lower end of the shell 11 is provided with a limiting clamping head 14, the outer wall of the upper end of the bottle body 21 (namely, the circumferential outer wall of the step) is correspondingly provided with a limiting guide groove 28, and the limiting guide groove 28 is used for guiding the limiting clamping head 14 to move according to a set path when the liquid storage bottle is assembled and connected with the atomizing head.
For example, in the present embodiment, the positioning and limiting guide groove 28 includes an axially disposed guiding section 281 and a circumferentially disposed screwing section 282. The upper end of the introducing section 281 penetrates through the upper end of the outer wall of the bottle body 21, and the right end of the screwing section 282 is communicated with the lower end of the introducing section 281, i.e. when the liquid storage bottle 2 is assembled with the atomizing head 1, the atomizing head 1 rotates leftwards relative to the liquid storage bottle 2 (the liquid storage bottle 2 rotates rightwards relative to the atomizing head 1), i.e. the assembling direction. The limiting guide groove 28 is arranged, so that after the liquid storage bottle 2 is assembled with the atomizing head 1, the freedom degrees of the liquid storage bottle 2 along the axial direction are limited.
In addition, a thrust block 15 is further disposed in the housing 11, and the thrust block 15 is specifically disposed on the bottom surface side of the upper section of the support member 131 in the liquid guiding structure 13. So set up, when a new stock solution bottle 2 carries out first assembly connection with atomising head 1 (i.e. spacing dop 14 is leading-in to leading-in section 281), thrust piece 15 is located just with between the dogtooth 24 and multiplexing dogtooth 25, and along with stock solution bottle 2 and atomising head 1 along assembly direction relative rotation, thrust piece 15 then drives snap ring 23 along the formula direction rotation to working position department through promoting just with the dogtooth 24, the degree of freedom along the circumference direction between stock solution bottle 2 and atomising head 1 is also restricted this moment, the assembly position between stock solution bottle 2 and atomising head 1 has basically been realized firm.
Finally, the present embodiment is also configured such that the left end side of the positioning teeth 26 and the positioning grooves 27 (in practice, one of them may be provided) are each provided with an assembly guide angle, such as a wedge angle, adapted to enable relative rotation of both in the assembly direction. While the right end sides of the positioning teeth 26 and the positioning grooves 27 are arranged parallel to the end face of the axis of the snap ring 23 so that the snap ring 23 can only rotate unidirectionally in the fitting direction in the tip groove 210. In addition, the left end side of the multiplexing tooth 25 is provided with an escape guide angle, such as a wedge angle, adapted to escape the thrust block 15 in a direction opposite to the fitting direction. So set up, after stock solution bottle 2 finishes using, can reverse rotation stock solution bottle 2, make thrust piece 15 withdraw from along multiplexing the exit guide angle of tooth 25 left end one side, until spacing dop 14 returns to leading-in section 281, can separate stock solution bottle 2 and atomising head 1.
It will be appreciated that when the liquid storage bottle 2 is repeatedly installed and used, that is, when the liquid storage bottle 2 and the atomizing head 1 are repeatedly assembled and connected, the thrust block 15 is located at the right end side of the multiplexing protruding tooth 25, and as the liquid storage bottle 2 and the atomizing head 1 rotate relatively again along the assembling direction, the thrust block 15 drives the snap ring 23 to leave the working position along the assembling direction by pushing the multiplexing protruding tooth 25. At this time, the user can determine whether the liquid storage bottle 2 is repeatedly assembled by observing whether the snap ring 23 is located at the working position.
Based on this, the present embodiment provides the atomizing device further including a state indicating structure for indicating whether the liquid reservoir 2 is connected for the first time (i.e., whether the snap ring 23 is in the working position).
Specifically, the status indicating structure includes two power receivers 16, two power supplies 29, and two double-ended spring pins 30. The two power receivers 16 are located in the housing 11, and the two power receivers 14 are respectively and fixedly disposed in two mounting holes formed in the upper section of the support member 132, and the atomizing sheet 12 in the atomizing head 1 is electrically connected between the two power receivers 16 through a wire or directly. The two power supplies 29 are respectively fixedly installed in axial through holes formed in the side walls of the bottle body 21, and the lower ends of the two power supplies 29 are respectively connected with a power supply positive electrode and a power supply negative electrode of the atomizing device. The snap ring 23 is provided with two axial through holes, and the two double-ended spring pins 30 are fixedly installed in the two axial through holes, respectively. In addition, if and only if the snap ring 23 is in the working position, the upper ends of the two double-ended spring pins 30 are respectively in contact with the two power receivers 16, and the lower ends of the two double-ended spring pins 30 are respectively in contact with the two power supplies 29, so that the two power receivers 16, the two power supplies 29 and the two double-ended spring pins 30 form a closed circuit suitable for supplying power to the atomizing sheet 12, as shown in fig. 14. So set up, when stock solution bottle 2 and atomising head 1 are assembled and are connected, if observe the work of atomizing piece 12 circular telegram then can judge stock solution bottle 2 for first assembly, if observe the work of atomizing piece 12 circular telegram then can judge stock solution bottle 2 for repeated assembly, as shown in fig. 15.
Of course, for convenience of use and observation, the configuration status indication structure further includes an indicator lamp fixedly installed at a position suitable for being observed by a user, such as a surface of the housing 11 or the bottle body 21, and the indicator lamp is connected in series between the two power receiving bodies 16 or the two power supplying bodies 29. The liquid storage bottle 2 is judged by observing the on-off state of the indicator lamp, namely, when the liquid storage bottle 2 is assembled and connected with the atomizing head 1, the liquid storage bottle 2 is assembled for the first time if the indicator lamp is on, and the liquid storage bottle 2 is assembled for the second time if the indicator lamp is not on. In general, the surface of the atomizing device is suitable for being touched and can be provided with a switch, the switch is connected in a loop where the indicator lamp is located in series, the on-off state of the indicator lamp is observed through operating the switch, and the working state of the atomizing sheet 12 is correspondingly controlled through the switch, so that the condition that the atomizing sheet 12 is put into operation immediately after the liquid storage bottle 2 is assembled for the first time is avoided.
It can be seen that the liquid storage bottle 2 has three status positions of before the first assembly, after the first assembly (i.e. before the repeated assembly) and after the repeated assembly, and each status position corresponds to one position of the snap ring 23 in the top end groove 210. That is, among the three positioning grooves 27, the pitch of any adjacent two positioning grooves 27 is adapted to the screwing distance of the liquid storage bottle 2 with respect to the atomizing head 1 when the liquid storage bottle 2 is assembled, so that the positioning teeth 26 of the lower end face of the snap ring 23 can be respectively engaged with one of the three positioning grooves 27 before, after (i.e., before) and after the initial assembly of the liquid storage bottle 2.
In summary, the use process of the atomizing device capable of preventing the liquid storage bottle from being reused provided by the embodiment of the invention is as follows:
when the liquid storage bottle 2 is first assembled and connected with the atomizing head 1, the limit clamping head 14 on the inner side wall of the shell 11 firstly enters the guide section 281 of the limit guide groove 28, moves to the lower end and then moves to the left in the screwing section 282 of the limit guide groove 28, and in the process of rotating the liquid storage bottle 2 relative to the atomizing head 1 along the assembly direction, the thrust block 15 drives the clamping ring 23 to rotate to the working position along the assembly direction by pushing the primary convex teeth 24. At this time, the upper ends of the two double-ended spring pins 30 in the snap ring 23 are respectively contacted with the two power receivers 16 in the atomizing head 1, and the lower ends of the two double-ended spring pins 30 in the snap ring 23 are respectively contacted with the two power supplies 29 in the liquid storage bottle 2, so that the two power receivers 16, the two power supplies 29 and the two double-ended spring pins 30 form a closed loop suitable for supplying power to the atomizing sheet 12, as shown in fig. 14, and meanwhile, the indication lamp is on, so that a user can quickly know that the liquid storage bottle 2 is in primary assembly connection.
After the liquid storage bottle 2 is used, the liquid storage bottle 2 can be reversely rotated, so that the thrust block 15 is withdrawn along the withdrawal guide angle at one side of the left end of the multiplexing convex tooth 25 until the limiting clamping head 14 is withdrawn into the leading-in section 281, and the liquid storage bottle 2 can be separated from the atomizing head 1. When the liquid storage bottle 2 is repeatedly installed and used, namely when the liquid storage bottle 2 and the atomizing head 1 are repeatedly assembled and connected, the thrust block 15 is positioned on the right end side of the multiplexing convex tooth 25, and along with the fact that the liquid storage bottle 2 and the atomizing head 1 rotate relatively again along the assembly direction, the thrust block 15 drives the clamping ring 23 to leave the working position along the assembly direction by pushing the multiplexing convex tooth 25, at the moment, the position relationship between the atomizing head 1 and the liquid storage bottle 2 is not changed relative to the first assembly of the two, so that the double-ended spring needle 30 is staggered with the power receiver 16 and the power supply 29 at the same time, namely, a closed loop is disconnected, as shown in fig. 15, an indicator lamp is not on (the atomizing sheet 12 is not electrified), and a user can quickly know that the liquid storage bottle 2 is repeatedly assembled and connected.
Example two
In this embodiment, as shown in fig. 8 and 10, in order to reduce the possibility of reverse rotation of the snap ring 23 when the liquid storage bottle 2 is detached from the atomizing head 1, two positioning teeth 26 are arranged and circumferentially spaced apart, and three sets of corresponding positioning grooves 27 are correspondingly provided. In order to reduce the number of the positioning grooves 27, the distance between any two adjacent positioning grooves 27 and the distance between the two positioning teeth 25 are all the same as the screwing distance of the positioning grooves 27 relative to the atomizing head 1 when the liquid storage bottle 2 is assembled, so that the positioning grooves 27 only need to be configured in four ways, namely, every two adjacent positioning grooves 27 form a group, and three groups are provided in total and correspond to three state positions of the clamping ring 23 respectively.
Example III
In this embodiment, as shown in fig. 4 and 6, a constraint structure is disposed between the limiting guide groove 28 and the limiting chuck 14, and the constraint structure provides a resistance for preventing the limiting chuck 14 from being withdrawn from the screwing section 282, that is, only when the liquid storage bottle 2 (or the atomizing head 1) is subjected to a torsion force exceeding a predetermined value, the limiting chuck 14 is allowed to withdraw from the screwing section 282, so that the liquid storage bottle 2 can be further prevented from rotating in the reverse assembly direction relative to the atomizing head 1.
For example, the constraint structure includes a protrusion (in a circular arc shape or a spherical shape) disposed at an upper end of the limiting chuck 14, and includes a notch disposed at an upper side of the screwing section 282 and adapted to the protrusion, wherein a width of the limiting chuck 14 in a vertical direction is adapted to a width of the screwing section 282 in a vertical direction. Therefore, when the limiting chuck 14 enters the screwing section 282, the screwing section 282 is forced to elastically deform until the protrusion at the upper end of the limiting chuck 14 enters the notch of the screwing section 282, and the screwing section 282 is deformed and recovered, when the liquid storage bottle 2 needs to be detached from the atomizing head 1, enough torsion force must be applied to force the screwing section 282 to deform until the limiting chuck 14 and the protrusion thereon can withdraw from the notch of the screwing section 282.
Typically, a notch is provided on the left end side of the screwing section 282, i.e., at the screwing end of the stopper 14 in the stopper guide slot 28, to prevent the occurrence of excessive screwing when the liquid storage bottle 2 is assembled.
Of course, the constraint structure may also be configured to include a spring ball fixedly mounted (axially embedded in the bottle 21 and protruding into the screwed-in section 282), and the limit chuck 14 may be correspondingly provided with a ball recess for cooperation.
Example IV
In this embodiment, as shown in fig. 6 to 7 and fig. 10 to 11, the status indication structure is different, and includes a circumferential through groove 20 provided on the side wall of the bottle body 21 and an indication block 17 located in the circumferential Xiang Tong groove 20 and fixedly attached to the outer wall of the snap ring 23.
In this way, the user can determine whether the liquid storage bottle 2 is in the working position by judging the position of the indicating block 17 in the circumferential through groove 20, and the working position is a virtual concept, and the meaning is different from that of the first embodiment, and the atomizing device can be configured only in the working position, but is used for indicating one position meaning.
In addition, the circumferential length of the circumferential through groove 20 is configured to be adapted to: the indicator blocks 17 are located at the right, middle and left ends of the circumferential through groove 20, respectively, when the liquid storage bottle 2 is assembled with respect to the atomizing head 1 before the initial assembly, after the initial assembly (i.e., before the repeated assembly), and after the repeated assembly.
Example five
In this embodiment, as shown in fig. 10-11, the circumferential side wall of the snap ring 23 is provided with a hollow hole 230, and the primary teeth 24, the multiplexing teeth 25 and the positioning teeth 26 are opposite to the hollow hole 230 in a direction parallel to the circumferential direction of the snap ring 23. So set up, on the one hand, when the liquid storage bottle 2 is assembled, because of the existence of the hollowed-out hole 230, the positioning convex teeth 26 can be upwards protruded and deformed, and then enter into the other positioning groove 27 from one positioning clamp groove 27; on the other hand, when the liquid storage bottle 2 is disassembled after being assembled for the first time, the hollow hole 230 is formed, so that the thrust block 15 can force the multiplexing convex tooth 25 to be sunken downwards, and the thrust block 15 is convenient to withdraw. By means of the arrangement, the clamping ring 23 can be made of materials with high rigidity strength in material selection, and then the local rigidity of the clamping ring 23 is reduced in a targeted manner through the arrangement of the hollowed-out holes 230, so that the integral structural strength of the clamping ring 23 is ensured, the clamping ring 23 can rotate along with the assembly of the liquid storage bottle 2 and the anti-thrust block 15 is allowed to withdraw when the liquid storage bottle 2 is disassembled.
The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
