Description

Technical Field

[0001] This disclosure relates to the field of aroma diffuser technology, and more particularly to a wall-mounted aroma diffuser with a dual-purpose locking structure. Background Technology

[0002] With the rapid development of society and economy and the continuous improvement of residents' living standards, people are paying more and more attention to the pursuit of quality of life, and the problem of bathroom odor has received much attention. Currently, the traditional method for removing bathroom odors on the market is using solid, paste-like air fresheners. These air fresheners rely mainly on the natural evaporation of the paste to release fragrance, but the fragrance diffusion is uneven, and the fragrance gradually weakens over time, significantly reducing the deodorizing effect. To overcome the shortcomings of traditional methods, aromatherapy diffusers that use the Venturi principle to cold-mist essential oils are being applied to bathroom odor removal. Compared to solid, paste-like air fresheners, using these diffusers has the following advantages: 1. The device atomizes essential oils into the air, resulting in a uniform fragrance, wide coverage, and long duration, with minimal difference in effect within the atomization cycle; 2. The operating frequency of the diffuser is adjustable, and the fragrance concentration can be adjusted according to the size of the space; 3. The device can be turned on and off at any time, unlike solid, paste-like air fresheners which lose their effectiveness after being opened and used for a short period. Therefore, the above-mentioned aroma diffusers can be widely used in public restrooms in shopping malls, office buildings, hospitals and other environments. However, the aroma diffusers face the problem of theft prevention in public restrooms. Therefore, it is necessary to optimize the existing aroma diffusers so that the assembly structure of the aroma diffusers integrates anti-theft functions. Utility Model Content

[0003] To achieve the goal of integrating an anti-theft function into the assembly structure of the aforementioned aroma diffuser, this utility model proposes a wall-mounted aroma diffuser with a dual-purpose locking structure. This dual-purpose locking structure locks the diffuser to the wall panel and simultaneously locks the back shell and the front shell, thus optimizing the assembly structure.

[0004] According to one aspect of this disclosure, a wall-mounted aroma diffuser with a dual-purpose locking structure is provided, comprising an aroma diffuser body and a wall-mounted panel. The aroma diffuser body includes a housing, a main control board disposed within the housing, an essential oil bottle, a micro air pump, and a two-fluid atomizing head assembly. The wall-mounted panel is fixed to the outer wall plane of a fixed object. The aroma diffuser body is hung on the wall-mounted panel via the back of the housing. The housing includes a back shell, a middle shell, and a front shell. The back shell has a first gourd-shaped hole located near the upper center of its back, and at least one second gourd-shaped hole located below the first gourd-shaped hole. Both the first and second gourd-shaped holes have small diameters facing upwards, and the axes of the first and second gourd-shaped holes are arranged parallel to the axis of the back shell. The front of the wall-mounted panel has a corresponding structure for the first and second gourd-shaped holes. The system includes a first connecting post and a second connecting post. Both sides of the first and second connecting posts have vertical slots for engaging with the small-diameter walls of the first and second gourd holes. The front end of the first connecting post has a horizontal slot. The main control board and the micro air pump are located inside the middle shell. The middle shell and the back shell are connected by screws. A slot is located at the center of the top of the middle shell. A hook post is located at the center of the inner top of the front shell. The rear side of the slot in the middle shell and the corresponding top position of the back shell form a mounting hole. A rotary latch is installed in the mounting hole. The rear end of the rotary latch engages with the horizontal slot, while the front end of the latch protrudes through the slot and engages with the hook post, simultaneously locking the back shell to the wall panel and the back shell to the front shell.

[0005] In one embodiment, the main control board is equipped with a power input interface, which connects to an external power source to power the main control board and the micro air pump.

[0006] In another embodiment, the back cover is provided with a battery compartment and a battery compartment cover below the second gourd hole. The battery compartment contains dry batteries, which power the main control board and the micro air pump.

[0007] Furthermore, a supercapacitor is provided inside the middle shell, and the supercapacitor is electrically connected to the main control board.

[0008] Furthermore, the two-fluid atomizing head assembly includes an atomizing head body, an atomizing nozzle, and an atomizing head cover. The atomizing head body is a shell including a bottom wall and side walls, with an open top. The atomizing head body has a gas channel and a liquid channel. The gas channel extends to the rear side of the atomizing head body to form a gas channel connector. The ends of the gas channel and liquid channel inside the atomizing head body are fitted with the atomizing nozzle. The liquid channel connects to the bottom of the atomizing head body. The bottom of the atomizing head body has a threaded port for connecting to an essential oil bottle. The lower end of the liquid channel is connected to a liquid guide tube extending into the bottom of the essential oil bottle. The atomizing head cover is placed over the upper opening of the atomizing head body, and the atomizing head cover has an upwardly angled spray nozzle. The front side of the middle shell has a connecting through hole for connecting to the gas channel connector, and the connecting through hole is connected to an air pipe connected to a micro air pump.

[0009] Furthermore, the outer periphery of the middle shell corresponding to the connecting through hole is provided with a contoured locking position for laterally fastening the atomizing head body. The bottle mouth of the essential oil bottle is provided with an inner plug, the center of which is provided with an insertion through hole for inserting the upper end of the liquid guide tube, and an air inlet is provided on the outer side of the insertion through hole to balance the air pressure inside the essential oil bottle when the liquid guide tube outputs liquid from the essential oil bottle.

[0010] Furthermore, the front side of the back cover is provided with a curved abutment for abutting against the side wall of the essential oil bottle. A liquid level detection transmitter plate and a liquid level detection receiver plate are respectively provided on the left and right sides of the curved abutment for detecting the liquid level in the essential oil bottle. The liquid level detection transmitter plate and the liquid level detection receiver plate are electrically connected to the main control board.

[0011] Furthermore, the wall-mounted panel is provided with a thickened base corresponding to the first connecting protrusion and the second connecting protrusion. The thickened base is provided with a countersunk hole, and the wall-mounted panel is connected and fixed to the outer wall plane of the fixing object by driving screws through the countersunk hole.

[0012] Furthermore, the lower ends of the back shell are symmetrically connected to the inner bottom sides of the front shell, and the front shell and the back shell are connected in a flip-top manner.

[0013] Compared with existing technologies, the wall-mounted aroma diffuser disclosed in this technical solution has the following advantages: A first gourd hole and a second gourd hole are provided on the back panel of the diffuser body; a first connecting post and a second connecting post are provided on the wall-mounted panel to connect to the first and second gourd holes; a horizontal groove is provided on the front end face of the first connecting post; and a rotary latch is provided at the top of the diffuser body. The rotary latch engages with the first and second connecting posts by hooking them onto the first and second gourd holes, respectively. The small-diameter hole wall of the gourd-shaped lock rotates, and the rear end of the rotating tongue engages with the horizontal slot. Simultaneously, the front end of the rotating tongue passes through the slot in the middle shell of the main body of the aroma diffuser and hooks into the hook post inside the front shell, thus locking the front shell to the back shell. Furthermore, because the rear end of the rotating tongue restricts the first connecting protrusion, the first connecting protrusion and the first gourd-shaped hole cannot move vertically relative to each other. That is, the vertical slots of the first and second connecting protrusions engage with the small-diameter hole walls of the first and second gourd-shaped holes, thereby locking the back shell to the wall-mounted panel. This optimized structural design makes it easier to prevent the aroma diffuser from being easily removed from the wall-mounted panel. The rotating tongue lock requires a key to open and rotate, causing the rear end of the rotating tongue to unscrew from the horizontal slot of the first connecting protrusion, allowing the aroma diffuser to be separated from the wall-mounted panel. This achieves the anti-theft purpose of the aroma diffuser in public restrooms in environments such as shopping malls, office buildings, and hospitals. Attached Figure Description

[0026] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.

[0027] Please refer to Figures 1 to 10This is a specific embodiment of a wall-mounted aroma diffuser with a dual-purpose locking structure disclosed in this technical solution. In this embodiment, the wall-mounted aroma diffuser includes a diffuser body 1 and a wall-mounting plate 2. The diffuser body 1 includes a shell, a main control board 14 disposed within the shell, an essential oil bottle, a micro air pump 16, and a two-fluid atomizing head assembly 17. The wall-mounting plate 2 is fixed to the outer wall plane of a fixed object. The diffuser body 1 is hung on the wall-mounting plate 2 via the back of the shell. The shell includes a back shell 11, a middle shell 12, and a front shell 13. The back of the back shell 11 is centered near the upper end. The wall-mounted panel 2 has a first gourd-shaped hole 111 and at least one second gourd-shaped hole 112 on the back shell 11 below the first gourd-shaped hole 111. Both the first and second gourd-shaped holes 111 and 112 have small diameters facing upwards, and their axes are parallel to the axis of the back shell 11. The front of the wall-mounted panel 2 has a first connecting protrusion 21 and a second connecting protrusion 22 that are adapted to and connected to the first and second gourd-shaped holes 111 and 112, respectively. Both sides of component 2 are provided with vertical slots 201 for engaging with the small-diameter holes of the first gourd hole 111 and the second gourd hole 112; a horizontal slot 202 is provided on the front end face of the first connecting protrusion 21; the main control board 14 and the micro air pump 16 are located inside the middle shell 12; the middle shell 12 and the back shell 11 are connected by screws; a screw connecting post 124 is provided inside the middle shell 12; the back shell 11 is provided with screw holes 118 corresponding to the screw connecting post 124; and a slot 121 is provided at the center of the top of the middle shell 12. A hook post 131 is provided at the center of the inner top of the face shell 13. The rear side of the slot 121 of the middle shell 12 and the corresponding top position of the back shell 11 form a mounting hole. A rotary latch 18 is installed in the mounting hole. The rear end of the rotary latch 182 of the rotary latch 18 is engaged with the transverse slot 202, while the front end of the rotary latch 182 passes through the slot 121 and hooks with the hook post 131, thereby simultaneously locking the back shell 11 and the wall-mounted panel 2, and the back shell 11 and the face shell 13. In this embodiment, the rotary latch 18 is a rotary latch 18 with a triangular core lock cylinder 181.

[0028] In this embodiment, preferably, the wall-mounted panel 2 is provided with a thickened base 23 corresponding to the first connecting protrusion 21 and the second connecting protrusion 22. The thickened base 23 is provided with a countersunk hole 231. The wall-mounted panel 2 is connected and fixed to the outer wall of the fixing object by screws driven into the countersunk hole 231. The wall-mounted panel 2 is made of hard plastic injection molding, and the thickened base 23 is used to strengthen the wall-mounted panel 2. In some home scenarios, 3M double-sided tape or gel can be applied to the back of the wall-mounted panel 2 to adhere to the outer wall of the fixing object, such as the bathroom wall or the outer wall of the cabinet. In this solution, the purpose is to install and fix this wall-mounted aroma diffuser in public restrooms in public environments. This is mainly achieved by setting a rotary lock 18 to lock the wall-mounted panel 2 to the aroma diffuser body 1. Specifically, the wall-mounted panel 2 preferably has screws driven into the countersunk holes 231 to fix the wall-mounted panel 2 to the outer wall plane of the fixed object. The first gourd hole 111 and the second gourd hole 112 on the back of the aroma diffuser body 1 enter the first connecting protrusion 21 and the second connecting protrusion 22 of the wall-mounted panel 2 respectively and move downwards, so that the small-diameter hole walls of the first gourd hole 111 and the second gourd hole 112 are stuck in the vertical slots 201 of the first connecting protrusion 21 and the second connecting protrusion 22. At this time, the aroma diffuser body 1 cannot be separated from the wall-mounted panel 2 when pulled forward. When separation is required, the aroma diffuser body 1 needs to be moved upwards so that the small-diameter hole walls of the first gourd hole 111 and the second gourd hole 112 slide out of the vertical slots 201, so that the aroma diffuser body 1 can be pulled forward to separate from the wall-mounted panel 2. In this embodiment, the rotary latch 18, with its latch locking onto the transverse slot 202 on the first connecting protrusion 21 connected to the first gourd hole 111, restricts the relative movement of the aroma diffuser body 1, thereby locking the aroma diffuser body 1 and the wall-mounted panel 2 to achieve the purpose of anti-theft. At the same time, the front end of the rotary latch is hook-shaped, passing through the slot 121 of the middle shell 12 of the aroma diffuser body 1 and hooking onto the hooking post 131 in the front shell 13, thereby locking the middle shell 12 to the back shell 11. The rotary latch 18 achieves two functions in one lock, optimizing the connection and locking between the front shell 13 and the back shell 11.

[0029] Please refer to Figure 7 , Figure 8 Preferably, the lower ends of the back shell 11 are symmetrically connected to the inner bottom sides of the front shell 13, and the front shell 13 and the back shell 11 are connected in a flip-top manner. A pivot 117 is provided symmetrically on the left and right sides of the lower end of the back shell 11, and a pivot connection hole 132 is provided on the inner bottom side of the corresponding front shell 13 to achieve pivot connection with the pivot 117.

[0030] In some embodiments, the main control board 14 is provided with a power input interface 19, which connects to an external power source to power the main control board 14 and the micro air pump 16. That is, the aroma diffuser body 1 is powered by an external power source and does not have a built-in battery.

[0031] In other embodiments, the back cover 11 is provided with a battery compartment 113 and a battery compartment cover 114 below the second gourd hole 112. The battery compartment 113 contains dry cell batteries 115, which power the main control board 14 and the micro air pump 16. Preferably, three No. 1 dry cell batteries 115 are connected in series, and power is provided by replaceable dry cell batteries 115. This allows for flexibility in the placement of the aroma diffuser body 1, eliminating the need to install it next to a location with a dedicated power socket. It also eliminates the need for wiring for external power sockets, saving on construction work.

[0032] In some preferred embodiments, a supercapacitor 116 is provided inside the middle shell 12. The supercapacitor 116 is electrically connected to the main control board 14. Combined with the power supply of the dry cell battery 115 and the synergistic power supply of the supercapacitor 116, the supercapacitor 116 reduces the number of deep discharges of the dry cell battery 115 by undertaking high-frequency, high-current pulse loads (such as the start and stop of the atomizer). This is because, typically, a two-fluid atomizing aromatherapy diffuser starts atomizing for a period of time, then automatically stops for a period of time, and then automatically starts again for a period of time, and so on.

[0033] Please refer to Figure 2 , Figure 7 Specifically, the two-fluid atomizing head assembly 17 includes an atomizing head body 171, an atomizing nozzle 172, and an atomizing head cover 173. The atomizing head body 171 is a shell including a bottom wall and side walls, with an open top. The atomizing head body 171 has a gas channel 1711 and a liquid channel 1712. The gas channel 1711 extends to the rear side of the atomizing head body 171 to form a gas channel 1711 connector. The ends of the gas channel 1711 and the liquid channel 1712 in the atomizing head body 171 are sleeved with the atomizing nozzle 172. The liquid channel 1712 communicates with the bottom of the atomizing head body 171. The bottom of the atomizing head body 171 has a threaded opening for connecting to the essential oil bottle 15. The lower end of the channel 1712 is connected to a liquid guide tube 151 that extends into the bottom of the essential oil bottle 15; the atomizing head cover 173 is placed over the upper opening of the atomizing head body 171, and the atomizing head cover 173 is provided with an upwardly angled spray nozzle 1731; the front side of the middle shell 12 is provided with a connecting through hole 122 for connecting the gas channel 1711 connector, and the connecting through hole 122 is connected to an air tube 161 connected to the micro air pump 16. Preferably, the air tube 161 is integrally injection molded with silicone, and the head of the air tube 161 is connected to the connecting through hole 122 and is fitted with a connecting head that fits into the connecting through hole 122, and the gas channel 1711 connector is inserted into the connecting head to achieve a sealing connection.

[0034] Please refer to Figure 2 , Figure 7The outer periphery of the middle shell 12 corresponding to the connecting through hole 122 is provided with a contoured locking position 123 for laterally fastening the atomizing head body 171. The bottle mouth of the essential oil bottle 15 is provided with an essential oil bottle plug 152. The center of the essential oil bottle plug 152 is provided with an insertion through hole for inserting the upper end of the liquid guide tube 151. An air inlet is provided on the outer side of the insertion through hole to balance the air pressure inside the essential oil bottle 15 when the liquid guide tube 151 outputs liquid from the essential oil bottle 15. Preferably, the front side of the back shell 11 is provided with a curved abutment for abutting against the side wall of the essential oil bottle 15. A liquid level detection transmitter plate 153 and a liquid level detection receiver plate 154 are respectively provided on the left and right sides of the curved abutment for detecting the liquid level inside the essential oil bottle 15. The liquid level detection transmitter plate 153 and the liquid level detection receiver plate 154 are electrically connected to the main control board 14. The liquid level detection transmitter 153 and the liquid level detection receiver adopt the principle of photoelectric through-beam sensor. Multiple through-beam photoelectric elements are respectively set on the liquid level detection transmitter 153 and the liquid level detection receiver 154 at different liquid level heights. When the liquid level in the essential oil bottle 15 exceeds the height of one through-beam photoelectric element, due to the light refraction principle of the liquid, through-beam sensing cannot be formed, that is, the liquid level is above the height of the through-beam photoelectric element. Conversely, when the liquid level is below the height of the through-beam element, due to the light through-beam in the air medium, the photoelectric through-beam sensing realizes that the liquid level is below the height of the through-beam element, thereby realizing the detection of the liquid level in the essential oil bottle 15 and outputting the corresponding liquid level parameter information. In this embodiment, a module for displaying liquid level parameter information, such as an LED indicator or a display screen unit, and control buttons can be set, which is a conventional existing technical means.

[0035] The parts not described in detail in this technical solution specification are obvious to those skilled in the art and can be supplemented and improved based on existing technical knowledge. At the same time, those skilled in the art should understand that the above embodiments are merely preferred embodiments of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
