Description

Technical Field

[0001] This application relates to the field of aroma diffusers, and more particularly to a car aroma diffuser. Background Technology

[0002] In related technologies, some car air fresheners, which can be installed in cars, mostly work by atomization. That is, the essential oils are atomized by an atomizing plate to form droplets, which diffuse into the car's interior space to achieve the purpose of air purification and fragrance.

[0003] In some aroma diffusers, the essential oil in the diffuser bottle is drawn into the atomizing plate by the absorbent cotton wick, which then atomizes it. Therefore, when assembling the aroma diffuser, the absorbent cotton wick must be firmly pressed against the atomizing plate. If the two are not firmly pressed together, the absorbent cotton wick will not be able to supply the essential oil to the atomizing plate, resulting in the atomizing plate burning dry.

[0004] In related technologies, the absorbent cotton wick is often assembled inside an aromatherapy bottle, with one end inserted into the bottle and the other end extending out to abut against the atomizing plate in the atomizing head. In this type of aromatherapy diffuser, since the absorbent cotton wick is installed in the bottle, the length of the wick extending out of the bottle needs to be precisely controlled. If the extension length is too short, the end of the wick will not be able to abut against the atomizing plate when the atomizing head is installed. Conversely, if the extension length is too long, the wick will be excessively compressed by the atomizing plate after the atomizing head is installed, which is not conducive to the moisture-wicking effect. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide a car air freshener.

[0006] To achieve the above objectives, this application provides the following technical solution.

[0007] A car air freshener includes: A container for holding aromatherapy liquid, which has an installation port; An atomizing assembly that can be detachably attached to a container includes a housing and an atomizing plate. The housing has a channel extending through the housing in a first direction. The atomizing plate is disposed within the channel. Due to the separation of the atomizing plate, the channel forms an atomizing port and an installation channel on both sides of the atomizing plate, respectively. The moisture-absorbing core is used to absorb the aromatherapy liquid in the container and transfer it to the atomizing plate for atomization. An adapter assembly is detachably inserted into an installation channel along a first direction. The moisture-absorbing core is inserted into the adapter assembly along the first direction. In the inserted state, the first end of the moisture-absorbing core extends out of the adapter assembly to form an abutment end, wherein the extension distance of the abutment end relative to the adapter assembly is limited by the adapter assembly. The second end of the moisture-absorbing core extends into the container through the installation port.

[0008] As an optional embodiment of this application, the moisture-absorbing core includes a docking section and a main body section in sequence along its own length direction. The docking section protrudes radially from the main body section to form a positioning surface. The end of the docking section constitutes the abutting end. In the plugged state, the positioning surface abuts against the adapter to restrict the moisture-absorbing core from moving away from the atomizing plate along the first direction.

[0009] As an optional embodiment of this application, the adapter includes a through hole for the moisture-absorbing core to pass through, and the through hole has a stepped surface, in which the positioning surface and the stepped surface abut against each other when plugged in.

[0010] As an optional embodiment of this application, the adapter includes a main body and a positioning part disposed on the end side of the main body, the moisture-absorbing core is inserted into the positioning part and positioned by the positioning part; the end of the main body near the positioning part is inserted into the installation channel along a first direction.

[0011] As an optional embodiment of this application, the main body extends at least partially out of the housing along a first direction to form a force-bearing portion, which can be inserted into the mounting opening.

[0012] As an optional embodiment of this application, the main body is a tubular structure extending along a first direction, and the moisture-absorbing core is disposed in the main body; the outer peripheral wall and / or bottom wall of the main body has an opening.

[0013] As an optional implementation of this application, a limiting component is provided in the channel to limit the insertion depth of the adapter assembly in the installation channel.

[0014] As an optional embodiment of this application, the adapter assembly is threaded into the mounting channel to achieve insertion; and / or the housing and container are threaded together to achieve mutual assembly.

[0015] As an optional embodiment of this application, the housing has a receiving space.

[0016] As an optional embodiment of this application, the housing includes a first housing and a second housing; the first housing and the second housing together form the receiving space.

[0017] Compared with the prior art, this application has the following advantages: In this application, an adapter assembly is used to transfer the moisture-absorbing core between the container and the atomizing assembly. During installation, the moisture-absorbing core is directly installed on the adapter assembly, which also positions the moisture-absorbing core to ensure that the length of the abutment end of the absorption component is fixed. This ensures that the moisture-absorbing core is at a suitable length to abut against the atomizing plate, thus preventing the moisture-absorbing core from being excessively squeezed by the atomizing plate during the extension process, and also preventing the moisture-absorbing core from being unable to abut against the atomizing plate due to insufficient length.

[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figures 1-9 As shown in the figure, this embodiment provides a car air freshener, which mainly includes a container, an atomizing component 2, a moisture-absorbing core 3, an adapter component 4, etc. The following is a detailed description of each component.

[0024] The container is primarily used to hold aromatherapy liquids, such as essential oils, etc., and in some embodiments, such as Figure 5 As shown, a bottle body 1 with a bottle mouth is used as a container. The bottle body 1 can be cylindrical or other shapes, which are not specifically limited here. The bottle mouth of the bottle body 1 serves as an installation port 111. Preferably, the top of the bottle body 1 extends upward a certain distance to form a bottle mouth 11, and the bottle mouth is located on the bottle mouth 11.

[0025] The atomizing component 2 is mainly used to atomize the fragrance liquid to form a fragrance liquid mist.

[0026] The atomizing component 2 is detachably mounted on the bottle body 1, for example, as shown below. Figure 3 As shown, the atomizing component 2 is installed on the nozzle 11 of the bottle body 1. At this time, the atomizing component 2 and the bottle body 1 are essentially two completely separable parts. When the aromatherapy liquid in the bottle body 1 is used up, the atomizing component 2 can be removed and aromatherapy liquid can be added back into the bottle body 1.

[0027] In this embodiment, the atomizing component 2 includes a housing 21 and an atomizing plate 22. The housing 21 has a channel extending through the housing 21 along a first direction. The first direction claimed in this embodiment is taken as a reference from the perspective of the entire aroma diffuser in its assembled state. At this time, the first direction can also be understood as the axial direction of the bottle body 1, or the height direction of the entire aroma diffuser.

[0028] like Figure 4 As shown, the channel here mainly serves as the installation space for the atomizing plate 22 and as an atomizing channel. The atomizing plate 22 is located in the channel, and the channel forms an atomizing port 23 and an installation channel 24 on both sides of the atomizing plate 22. The atomizing plate 22 is set horizontally, which can also be understood as its inlet being perpendicular to the first direction.

[0029] The atomizing port 23 is located above the atomizing plate 22 and is mainly used for the output of the atomized aromatherapy liquid, while the installation channel 24 is mainly used as the installation space for the adapter component 4.

[0030] like Figure 7 As shown, the atomizing plate 22 is basically circular in shape, mainly including the atomizing plate body 221 in the middle and the annular retainer 222 around the atomizing plate body 221. When working, the hygroscopic core 3 draws the aromatherapy liquid in the bottle 1 into the atomizing plate 22, and then the atomizing plate 22 works to atomize the aromatherapy liquid. The atomized aromatherapy liquid escapes through the atomizing port 23.

[0031] The moisture-absorbing core 3 is used to absorb the aromatherapy liquid in the container and transfer it to the atomizing plate 22 for atomization. In some embodiments, the moisture-absorbing core 3 can be made of moisture-absorbing cotton or other materials that can transport the solution through capillary action; among them, such as Figure 2 and Figure 3 As shown, the moisture-absorbing core 3 is basically long and narrow. One part of it is inserted into the aromatherapy liquid inside the bottle 1, and the other part extends out of the bottle 1 through the installation port 111 and its rear end contacts the atomizing plate 22. In this way, the moisture-absorbing cotton core can draw the aromatherapy liquid inside the bottle 1 to the atomizing plate 22 and atomize it.

[0032] In some embodiments, the atomizing plate 22 is an electrical component, and the aroma diffuser also needs to be equipped with some related electrical components, such as PCB circuit boards, control components, etc. Therefore, the housing 21 has a receiving space 210 to serve as the installation space for these electrical components.

[0033] In some embodiments, a specific housing 21 structure is provided, the housing 21 including a first housing 211 and a second housing 212; the first housing and the second housing together form the receiving space 20.

[0034] The second housing 212 is generally straight tubular, and the first housing 211 is generally annular. The second housing 212 is fitted inside the first housing 211 to form the receiving space 20 and the channel, wherein the installation channel 24 is mainly formed by the internal channel of the second housing 212.

[0035] In some embodiments, to allow subsequent disassembly of housing 21, the first housing 211 and the second housing 212 may be detachably connected, for example, by means of screws. Specifically: The bottom outer periphery of the second housing 212 protrudes radially to form a second skirt 212a, and the inner side of the corresponding first housing 211 protrudes radially towards the center of the channel to form a second skirt 212a. The first skirt 211a and the second skirt 212a are attached to each other and connected by screws, thus realizing the connection between the first housing 211 and the second housing 212.

[0036] The adapter 4 is mainly used to transfer the moisture-absorbing core 3 to the housing 21 of the atomizing component 2, and it can be detachably inserted into the mounting channel 24 along the first direction.

[0037] The moisture-absorbing core 3 can be inserted into the adapter 4 along the first direction, and in the inserted state, the first end of the moisture-absorbing core 3 extends out of the adapter 4 to form an abutment end, so as to... Figure 2 As shown in the example, the upper end of the moisture-absorbing core 3 serves as the contact end.

[0038] The extension distance of the contact end relative to the adapter 4 is limited by the adapter 4. That is, after the moisture-absorbing core 3 is installed in place on the adapter 4, as... Figure 8 As shown, the length of the moisture-absorbing core 3 extending beyond the adapter assembly 4 is fixed. Therefore, when replacing the moisture-absorbing core 3 later, as long as it is installed correctly as required, the extension length of the moisture-absorbing core 3 will be within a suitable range, ensuring that the contact end of the moisture-absorbing core 3 contacts the atomizing plate 22 in a suitable position. The second end of the moisture-absorbing core 3 extends into the container through the mounting port 111.

[0039] In order to ensure that the extension distance of the abutting end relative to the adapter 4 is limited by the adapter 4 in the plugged-in state, in some embodiments, a specific positioning structure is provided, specifically: like Figure 2 As shown, the moisture-absorbing core 3 includes a docking section 32 and a main body section 31 along its own length direction (which can also be understood as the axial direction of the moisture-absorbing core 3). Specifically, in this embodiment, the docking section 32 is located on the upper side of the main body section 31, and the two are basically coaxially arranged.

[0040] Among them, such as Figure 9As shown, the diameter of the docking section 32 is larger than the diameter of the main body section 31, such that the docking section 32 protrudes radially from the main body section 31 to form a positioning surface 33. The positioning surface 33 herein can also be understood as the lower end surface of the docking section 32, and correspondingly the upper end surface of the docking section 32 forms the aforementioned abutting end.

[0041] Correspondingly, in some embodiments, to adapt to the aforementioned moisture-absorbing core 3, a specific adapter assembly 4 is provided, as Figure 4 and Figure 9 shown, the adapter assembly 4 includes a through hole 421 for the moisture-absorbing core 3 to pass through, and a step surface 422 is provided in the through hole 421. In this case, the through hole 421 is equivalent to an inverted convex-shaped hole, and the step thereof forms the aforementioned step surface 422. At this time, the portion of the through hole 421 located on the upper side of the step surface 422 (i.e., the first portion) is adapted to the docking section 32. Preferably, the docking section 32 can be inserted into the first portion of the through hole 421 in an interference fit manner. The portion of the through hole 421 located on the lower side of the step surface 422 (i.e., the second portion) is adapted to the main body section 31. Preferably, the diameter of the second portion of the through hole 421 is larger than the diameter of the main body section 31, so that the main body section 31 can freely pass through the second portion of the through hole 421.

[0042] Thus, when installing the moisture-absorbing core 3, it is only necessary to pass the moisture-absorbing core 3 through the through hole 421 from the upper side to the lower side. As the moisture-absorbing core 3 is inserted downward, the positioning surface 33 of the moisture-absorbing core 3 will eventually abut against the step surface 422 of the through hole 421, and at this time the moisture-absorbing core 3 cannot continue to be inserted downward, so the moisture-absorbing core 3 is installed in place. That is, under the mutual positioning of the positioning surface 33 and the step surface 422, the movement of the moisture-absorbing core 3 along the first direction away from the atomizing sheet 22 (i.e., moving downward) can be limited.

[0043] In addition, in order that the adapter assembly 4 can be attached to the atomizing assembly 2, in some embodiments, as Figure 8 shown, the adapter assembly 4 includes a main body portion 41 and a positioning portion 42 provided at an end side of the main body portion 41. The moisture-absorbing core 3 is plugged onto the positioning portion 42 and positioned by the positioning portion 42, that is, the aforementioned through hole 421 is provided on the positioning portion 42.

[0044] Correspondingly, the end of the main body portion 41 close to the positioning portion 42 (i.e., the upper end of the main body portion 41) is plugged into the installation channel 24 along the first direction. For example, the main body section 31 is installed in the installation channel 24 by means of threaded connection, specifically: The main body 41 is roughly cylindrical, allowing the moisture-absorbing core 3 to be inserted into the pipe of the main body 41. In addition, the upper part of the main body 41 can be inserted into the installation channel 24, and the upper outer peripheral wall of the main body 41 is provided with a first thread. The corresponding installation channel 24 is provided with a first thread that matches the first thread. The main body 41 is installed into the installation channel 24 by the mutual threading of the first thread and the second thread.

[0045] The positioning part 42 can be fixed to the upper end of the main body part 41 in a non-removable manner, such as by welding them together or by making them an integral structure. Alternatively, they can be connected in a detachable manner, such as by using a threaded connection so that the positioning part 42 can be screwed into the main body part 41, or the positioning part 42 can be fixed into the main body part 41 by an interference fit. Of course, there are other connection methods as well, which will not be listed here.

[0046] Since the main body 41 is screwed into the mounting channel 24, in some embodiments, such as... Figure 6 As shown, the main body 41 extends at least partially out of the shell 21 along the first direction to form a gripping part, that is, the main body 41 extends downward out of the shell 21 to serve as a gripping part for human hand to hold.

[0047] Furthermore, the size of the force-bearing part is configured such that the force-bearing part can pass through the mounting opening 111, so that the main body 41 can be inserted into the bottle body 1 during installation.

[0048] Since the absorbent cotton wick is located inside the main body 41, in order for the absorbent cotton wick to come into contact with the fragrance liquid inside the bottle 1, in some embodiments, such as... Figure 6 As shown, the outer peripheral wall and / or bottom wall of the main body 41 have a through-hole 411, so that the aromatherapy liquid in the bottle 1 can enter the main body 41 through the through-hole 411 to come into contact with the moisture-absorbing cotton core.

[0049] It is worth noting that since the moisture-absorbing core 3 is pre-installed on the adapter assembly 4, the screw-in depth of the adapter assembly 4 in the installation channel 24 also determines whether the abutting end of the moisture-absorbing core 3 can abut against the atomizing plate 22. In some embodiments, such as... Figure 4 As shown, a limiting component 25 is provided in the channel to limit the insertion depth of the adapter 4 in the mounting channel 24.

[0050] In some embodiments, the limiting member 25 is basically annular and is fixed inside the second housing 212. The lower end of the limiting member 25 serves as a limiting surface. As the main body 41 is continuously screwed in, the positioning part 42 on the main body 41 will eventually abut against the lower end of the limiting member 25. At this point, the main body 41 can no longer be screwed in, thus achieving the purpose of limiting.

[0051] The atomizing plate 22 is pressed between the first housing 211 and the limiting member 25 in the first direction, thereby realizing the installation of the atomizing plate 22.

[0052] To prevent the atomizing plate 22 from rotating relative to the housing 21 during installation, in some embodiments, such as Figure 7 As shown, a protruding key 223 is provided on the peripheral wall of the atomizing plate 22. Correspondingly, a keyway 212b is provided on the top peripheral wall of the second housing 212 for the protruding key 223 to be inserted. With the cooperation of the protruding key 223 and the keyway 212b, the atomizing plate 22 can be prevented from rotating relative to the housing 21. Of course, the electrical wires of the atomizing plate 22 can also be led out from the protruding key 223.

[0053] In some embodiments, the housing 21 can be connected to the bottle body 1 by means of threaded engagement. For example, the bottle mouth 11 of the bottle body 1 is provided with a third thread on its outer peripheral wall, and the bottom of the first housing 211 is a threaded hole that allows the bottle mouth 11 of the bottle body 1 to be inserted vertically, so that the bottle mouth 11 of the bottle body 1 can be screwed into the bottom of the first housing 211.

[0054] In order to improve the sealing performance of the main body 41 at the bottle mouth 11 after it is inserted into the bottle body 1, in some embodiments, an annular rubber block 12 is inserted into the bottle mouth 11 of the bottle body 1, and the main body 41 extends into the bottle body 1 after passing through the rubber block 12 with an interference fit. In this way, the sealing performance between the bottle mouth 11 and the main body 41 is improved by the rubber block 12.

[0055] In this embodiment, a transfer component 4 is used to transfer the moisture-absorbing core 3 between the container and the atomizing component 2. During installation, the moisture-absorbing core 3 is directly installed on the transfer component 4, and the transfer component 4 can position the moisture-absorbing core 3 to ensure that the length of the abutment end of the absorption component is fixed. This ensures that the moisture-absorbing core 3 is at a suitable length to abut against the atomizing plate 22. This can prevent the moisture-absorbing core 3 from being excessively squeezed by the atomizing plate 22 during the extension process, and also prevent the moisture-absorbing core 3 from being unable to abut against the atomizing plate 22 due to insufficient length.

[0056] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
