Description

Technical Field

[0001] This utility model relates to the technical field of wall-mounted diffusers, specifically to a diffuser. Background Technology

[0002] A wall-mounted diffuser is a fragrance diffusion device that is plugged into a wall socket. It mainly releases fragrance into indoor spaces to create a comfortable and pleasant atmosphere. Therefore, it is also widely used in mid-to-high-end places such as hotel lobbies, guest rooms, car showrooms, and department stores.

[0003] However, existing wall-mounted diffusers still have some limitations, especially in terms of the adaptability of the plug direction. For example, Chinese patent CN119259302A discloses an atomizer and diffuser, which specifically discloses "including a shell, an air pump, and a plug assembly. By installing the plug assembly on the side wall of the shell, when the diffuser is in use, it is plugged into the socket, and the air pump is connected to the power supply through the plug assembly. After the air pump is powered on, it turns on and continuously delivers high-pressure gas into the atomizing cover." This diffuser has a certain defect in use, namely, the angle of the plug assembly is not adjustable.

[0004] Specifically, the orientation of wall socket holes can vary depending on the installation location, especially for some US, European, and British standard sockets, which may have horizontal, vertical, or other angled holes. For corded diffusers (generally referring to diffusers with a power cord), the power cord's length allows them to adapt well to different hole orientations. However, for wall-mounted diffusers (i.e., those that plug directly into a wall socket and generally do not have a power cord), when the plug angle is not adjustable, users need to adjust the diffuser's insertion direction according to the hole orientation (e.g., rotating / tilting it at a certain angle), increasing the difficulty of use. Furthermore, for diffusers using liquid aromatherapy, if the diffuser is inserted into the socket at an angle or other angle, the aromatherapy liquid may leak, causing waste and contamination.

[0005] Therefore, it is necessary to improve upon existing technology and provide a diffuser that is more adaptable to the direction of the jack. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a diffuser with better adaptability to the direction of the insertion hole.

[0007] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0008] A diffuser includes a plug assembly and a diffuser body. The plug assembly is rotatable relative to the diffuser body. The diffuser body includes a housing and an atomizing mechanism disposed within the housing. The plug assembly includes prongs. When the plug assembly rotates, it can drive the prongs to rotate relative to the housing to adjust the direction in which the prongs are inserted into the socket.

[0009] Preferably, the plug assembly is provided with a first sliding element, and the outer shell is provided with a second sliding element. The first sliding element and the second sliding element cooperate to allow the plug assembly to rotate relative to the diffuser body.

[0010] The first sliding element and the second sliding element are respectively a sliding groove and a slider; the sliding groove extends along the circumferential direction of the plug assembly.

[0011] Preferably, the rotation angle of the plug assembly is 90°±5°; the arc of the circumferential extension of the slide groove is θ, where θ≥95°.

When the slider moves to abut against the first abutment wall of the limiting boss, the damping member can abut against the second abutment wall of the limiting boss.

[0013] Preferably, a connecting seat is provided on the outer shell, the connecting seat is fixedly connected to the outer shell, the plug assembly can rotate relative to the connecting seat, the slider is provided on the plug assembly, the slide groove is provided in the connecting seat, and the opening of the slide groove faces the axis of the connecting seat.

[0014] Preferably, the plug assembly further includes a base plate, a slider on the base plate, and a groove in the housing, the groove being annularly arranged within the housing. The outer periphery of the base plate and the slider are both embedded in the groove and can rotate along the groove.

[0015] Preferably, the plug assembly further includes a base plate, and the slider and damping element are both disposed on the base plate. The damping element includes a protrusion and a recess, with the recess located on both sides of the protrusion. When the slider moves to abut against the first abutting wall of the limiting protrusion, the protrusion can abut against the second abutting wall of the limiting protrusion.

[0016] Preferably, the outer casing is provided with a connector, the plug assembly is rotatable relative to the connector, the connector is provided with a locking member and a fixing protrusion, there is a gap between the locking member and the fixing protrusion, the connector is also provided with a control board, the control board is installed in the gap; there are multiple locking members and fixing protrusions, and multiple locking members and fixing protrusions are arranged in a ring inside the connector.

[0033] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0034] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] refer to Figure 1-9This utility model provides a diffuser, which is mainly applicable to wall-mounted diffusers. It includes a plug assembly 2 and a diffuser body 1. The plug assembly 2 is rotatable relative to the diffuser body 1. The diffuser body 1 includes a housing 10 and an atomizing mechanism 11 disposed within the housing 10. The plug assembly 2 includes prongs 24. When the plug assembly 2 rotates, it can drive the prongs 24 to rotate relative to the housing 10, thereby adjusting the direction in which the prongs 24 are inserted into the socket. In this article, the socket refers to the socket or slot on a wall socket used to insert electrical plugs (such as a two-hole socket or a three-hole socket in a home). In this embodiment, the specific structure of the atomizing mechanism 11 is the same as the structure of the atomizing device disclosed in the applicant's patent CN222378336U. This part is prior art and will not be described in detail here.

[0037] This utility model provides an aroma diffuser, the specific working process of which is as follows:

[0038] When the plug assembly 2 is mismatched with the position or orientation of the wall socket, the user can manually rotate the plug assembly 2. During rotation, the plug assembly 2 will cause the prongs 24 to rotate relative to the diffuser body 1, thereby rotating the plug assembly 2 to a suitable angle. This allows the prongs 24 to be smoothly inserted into the socket without changing the orientation of the diffuser body 1, avoiding the risk of aromatherapy liquid leakage due to tilting of the diffuser body 1. Compared to products that require disassembly and reassembly to adjust the angle of the plug assembly 2, this diffuser maintains a constant connection between the plug assembly 2 and the diffuser body 1, making operation simpler and improving overall product stability.

[0039] Meanwhile, in order to meet different sales needs, the pin 24 in this embodiment can be adjusted to US standard, UK standard or European standard pin 24 in actual process to adapt to the specifications of different countries.

[0040] refer to Figure 1-9In a preferred embodiment, the plug assembly 2 is provided with a first sliding element, and the outer shell 10 is provided with a second sliding element. The first and second sliding elements cooperate to allow the plug assembly 2 to rotate relative to the diffuser body 1. One of the first and second sliding elements is a groove 30, and the other is a slider 21 (i.e., the first sliding element can be either a groove 30 or a slider 21, and the same applies to the second sliding element). The groove 30 extends along the circumferential direction of the plug assembly 2. In this embodiment, through the cooperation of the first and second sliding elements, when the plug assembly 2 rotates, the slider 21 slides within the groove 30. The groove 30 extends along the circumferential direction of the plug assembly 2, allowing the slider 21 to move smoothly along the circumferential direction within a certain range, thereby ensuring the stability of the rotation of the plug assembly 2. Compared to some methods that require repeated plugging and unplugging to adjust the plug angle, the adjustment method in this invention results in less wear on the product (mainly referring to less wear on the area where the first and second sliding elements meet). Repeated plugging and unplugging can lead to greater wear at the connection point, which may cause the plug to loosen over time and become unable to be adjusted to the required angle, thus affecting the product's lifespan.

[0041] In addition, the adjustment method of the sliding groove and the slider in this utility model allows consumers to directly adjust to the corresponding angle by simply turning the plug assembly 2. The adjustment method is more direct and convenient, and the stability is better.

[0042] For some diffusers that require disassembly for angle adjustment, there may be difficulties in aligning the two components during the adjustment process. If they are not properly aligned, the connection between the components may become loose, which can directly affect the normal power supply of the product, causing the diffuser to malfunction and resulting in numerous customer complaints. Moreover, the need for disassembly for angle adjustment actually increases the difficulty of adjustment.

[0043] The diffuser provided by this utility model has a plug assembly 2 that is always connected to the diffuser body 1, making the operation simpler, the overall product stability better, and improving the customer's user experience and customer satisfaction.

[0044] refer to Figure 3 When the slide groove 30 is provided on the plug assembly 2, the so-called circumferential direction refers to its extension along the circumference of the plug assembly 2. In other words, the extension direction of the slide groove 30 is actually set along the rotation trajectory of the plug assembly 2, thereby enabling the plug assembly 2 to rotate and adjust the direction in which the pin 24 is inserted into the socket. Conversely, if the slide groove 30 extends radially, the movement of the slider 21 within the slide groove 30 can only achieve radial movement of the plug assembly 2, and cannot achieve rotation, thus failing to achieve the desired rotational effect.

[0045] refer to Figure 6 In a preferred embodiment, the rotation angle of the plug assembly 2 is 90°±5°; the arc of the slide groove 30 extending circumferentially is θ, θ≥95°, to ensure that the arc of the slide groove 30 can meet the maximum rotation angle of the plug assembly 2, and the rotation angle of the plug assembly 2 is preferably 90°. In actual operation, the extension range of the slide groove 30 can cover part or all of the circumference according to design requirements, such as a quarter circumference (slightly larger than a quarter can also be considered as a quarter circumference, for example, θ=95° can also be considered as the slide groove 30 covering a quarter of the circumference), a half circumference (θ=180°), a three-quarter circumference (θ=270°) or the entire circumference (θ=360°). Considering production tolerances, the actual arc θ of the slide groove 30 is also allowed to have a certain angular deviation. The extension arc θ referred to here is the included angle formed by the distance from the two ends of the slide groove 30 to the center of the circle.

[0046] refer to Figure 5 and 6 In a preferred embodiment, two limiting bosses 31 are spaced apart in the slide groove 30. The slider 21 can move within the slide groove 30 between the two limiting bosses 31 to adjust the direction of the insertion of the pin 24 into the socket. Damping elements 22 are respectively provided on both sides of the slider 21. The limiting bosses 31 include a first abutting wall 310 and a second abutting wall 311. The first abutting wall 310 faces the slide groove 30 (facing the slide groove 30 means facing the slide groove 30 between the two limiting bosses 31), and the second abutting wall 311 faces away from the slide groove 30 (facing away from the slide groove 30 means away from the slide groove 30 between the two limiting bosses 31). It can also be understood that the first abutting wall 310 and the second abutting wall 311 are arranged opposite to each other.

[0047] When the slider 21 moves to abut against the first abutment wall 310 of the limiting boss 31, the damping member 22 can abut against the second abutment wall 311 of the limiting boss 31. In this embodiment, the slide groove 30 can be entirely encircled within the outer shell 10, or it can have an extension arc of 90° as in the above embodiment. In this case, by setting two limiting bosses 31, even if the slide groove 30 is entirely encircled within the outer shell 10, the sliding path of the slider 21 can only move between the two limiting bosses 31, thereby limiting the rotation angle range of the plug assembly 2. For example, if the included angle between the two limiting bosses 31 is 90°, the rotation angle range of the plug assembly 2 is approximately within 90°, which allows the user to adjust the plug assembly 2 to a suitable angle as needed, so that the pins 24 can be accurately inserted into sockets in different directions.

[0048] Furthermore, damping elements 22 are provided on both sides of the slider 21. When the slider 21 moves to abut against the first abutting wall 310 of the limiting boss 31, the damping element 22 abuts against the second abutting wall 311 of the limiting boss 31. By providing the damping element 22, a certain damping effect can be increased, and the stability of the plug assembly 2 after adjustment can be improved. Even under slight external vibration or tension, the plug assembly 2 can remain at the set angle position and will not easily shake or shift position and change angle.

[0049] refer to Figure 1 and 2 In a preferred embodiment, a connecting seat 3 is provided on the outer shell 10, and the connecting seat 3 is fixedly connected to the outer shell 10 (the fixed connection here means that the connecting seat 3 and the outer shell 10 are not detachable during normal use without considering maintenance). The plug assembly 2 can rotate relative to the connecting seat 3. The slider 21 is provided on the plug assembly 2, and the slide groove 30 is provided in the connecting seat 3, with the opening of the slide groove 30 facing the axis of the connecting seat 3.

[0050] refer to Figure 3 In a preferred embodiment, the plug assembly 2 further includes a base plate 20, on which a slider 21 is provided (specifically, the slider 21 is provided on the side of the base plate 20 facing the outer shell 10, and the pin 24 is provided on the side facing away from the outer shell 10). A sliding groove 30 is provided inside the outer shell 10, and the sliding groove 30 is annularly arranged inside the outer shell 10. The outer periphery of the base plate 20 and the slider 21 are both embedded in the sliding groove 30 and can rotate along the sliding groove 30.

[0051] In this embodiment, since the slide groove 30 is annular and the slider 21 can rotate along it, the user can operate the plug assembly 2 to move the slider 21 within the annular slide groove 30, thereby achieving rotation of the plug assembly 2 relative to the outer shell 10. This allows the plug to be adjusted to fit into sockets of different positions and orientations, improving the diffuser's versatility and ease of use. Simultaneously, the outer periphery of the base plate 20 and the slider 21 are both embedded within the slide groove 30. This fitting method ensures a tight and stable connection between the plug assembly 2 and the outer shell 10; that is, the plug assembly 2 will not detach from the outer shell 10 during use, and the plug assembly 2 always maintains a connection with the outer shell 10, only able to rotate relative to the outer shell 10.

[0052] refer to Figure 3-9In a preferred embodiment, the plug assembly 2 further includes a base plate 20, with a slider 21 and a damping element 22 both disposed on the base plate 20. The damping element 22 includes a protrusion 220 and a recess 221, with the recess 221 located on both sides of the protrusion 220. When the slider 21 moves to abut against the first abutment wall 310 of the limiting boss 31, the protrusion 220 can abut against the second abutment wall 311 of the limiting boss 31. After the plug assembly 2 rotates to its position, a damping force is generated by the abutment between the protrusion 220 and the second abutment wall 311. This damping force can prevent the plug assembly 2 from easily shifting its position when subjected to external forces, thereby ensuring the stability of the plug assembly 2 after adjustment.

[0053] refer to Figure 5 and 8 In a preferred embodiment, a connecting seat 3 is provided on the outer casing 10, and the plug assembly 2 is rotatable relative to the connecting seat 3. A locking member 34 and a fixing protrusion 35 are provided inside the connecting seat 3, with a gap between the locking member 34 and the fixing protrusion 35. A control plate 33 is also provided inside the connecting seat 3, and the control plate 33 is installed in the gap. Multiple locking members 34 and fixing protrusions 35 are arranged in a ring around the connecting seat 3. Under the action of the locking member 34 and the fixing protrusion 35, the control plate 33 can be firmly held in the gap. Multiple fixing protrusions 35 can achieve fixation of the control plate 33 in different directions, improving the stability of the control plate 33.

[0054] refer to Figure 7 and 8 In a preferred embodiment, the control board 33 divides the connector 3 into a first cavity 36 and a second cavity 37. The first cavity 36 is used to install electronic components. The fixing protrusion 35 and the clip 34 are located in the first cavity 36 and the second cavity 37, respectively. The control board 33 has a wiring hole 330 that connects the first cavity 36 and the second cavity 37. In this embodiment, the installation of the control board 33 divides the connector 3 into two cavities. Electronic components (not shown) can be installed in the first cavity 36, while the part that slides with the plug assembly 2 is mainly located in the second cavity 37. This allows for a reasonable division of the internal space of the connector 3, avoiding mutual interference. At the same time, the wiring hole 330 connects the first cavity 36 and the second cavity 37, allowing the wiring to easily extend from the first cavity 36 to the second cavity 37 and connect to the plug assembly 2, thus achieving circuit connection. The structural design is more rational.

[0055] refer to Figure 1-9In a preferred embodiment, the plug assembly 2 further includes a base plate 20, on which an annular flange 201 is formed. A terminal mounting position 202 is disposed within the annular flange 201, and a conductive sheet 23 electrically connected to the pin 24 is fixed on the terminal mounting position 202. The conductive sheet 23 is also electrically connected to the control board 33. In this embodiment, the annular flange 201 formed on the base plate 20 provides a specific area for the installation of other components (such as the terminal mounting position 202 and the conductive sheet 23). When the plug is inserted into the socket, the current from the external power supply flows into the conductive sheet 23 through the pin 24, and then through the conductive sheet 23 to the control board 33 via electrical connection, thereby enabling the control board 33 to send relevant signals to the air pump 110 of the atomizing mechanism 11 for operation, thus achieving the connection of the entire circuit.

[0056] refer to Figure 2 In a further preferred embodiment, the atomizing mechanism 11 includes an air pump 110, and a control switch 101 and a working indicator light 102 are provided on the outer casing 10. The air pump 110, control switch 101, and working indicator light 102 are all electrically connected to the control board 33. In this embodiment, the control switch 101 is used to control the on / off operation of the diffuser. During use, simply pressing the control switch 101 easily starts or stops the diffuser. The working indicator light 102 indicates the working status of the diffuser, allowing the user to quickly determine its operating condition.
