[0034] The sofa bed with the sleep-aiding function provided by the embodiment of the utility model can realize the convenient conversion of the sofa and bed two forms to meet the rest needs of the user at different time periods.

[0035] Referring to Figures 1 to 5 The sofa bed with the sleep-aiding function provided by the embodiment of the utility model comprises a sofa bed main body 1 and a sleep-aiding assembly 2. The sofa bed main body 1 comprises a bed body 11, the bed body 11 comprises a fixed part 111 and a movable part 112, the movable part 112 is movably connected with the fixed part 111 to enable the sofa bed main body 1 to be switched between the sofa form and the bed form; the sleep-aiding assembly 2 is embedded in the sofa bed main body 1, the sleep-aiding assembly 2 comprises an exciting component and a spray pipeline 23, the exciting component is used for generating sleep-aiding gas mist, the spray pipeline 23 is connected with the exciting component, and the sleep-aiding gas mist can enter the spray pipeline 23 and be sprayed towards the sofa bed main body 1.

[0036] The sofa bed with the sleep-aiding function provided by the embodiment of the utility model can realize the convenient conversion of the sofa and bed two forms to meet the rest needs of the user at different time periods.

[0037] The specific structure and implementation principle of the sofa bed with the sleep-aiding function will be described below.

[0038] In order to realize the switching of the sofa bed main body 1 between the sofa form and the bed form, the movable part 112 can be connected with one end of the fixed part 111 to enable the sofa bed main body 1 to form the bed form; and / or the movable part 112 can be loaded on the fixed part 111 to enable the sofa bed main body 1 to form the sofa form.

[0039] Specifically, when the sofa bed body 1 needs to be converted into a bed form, the movable part 112 is pushed to move along the length direction of the fixed part 111 to the end of the fixed part 111, then the two are aligned and locked by the locking part, so that the movable part 112 and the fixed part 111 jointly form a continuous bearing plane to form a complete bed support surface, which is convenient for users to lie down and sleep; when the sofa bed body 1 needs to be converted into a sofa form, the locking between the movable part 112 and the fixed part 111 is released, the movable part 112 is lifted and loaded above the fixed part 111, then the movable part 112 is pushed in the opposite direction, so that the two are stacked, at this time, the movable part 112 serves as a sitting and lying part, and the fixed part 111 serves as a supporting part at the bottom of the movable part 112, which jointly form a sofa form, which is convenient for users to sit and lie.

[0040] The locking part can be selected from buckles, hooks, slots and the like structures, which are all conventional technical means and will not be described here.

[0041] Specifically, the movable part 112 includes a horizontal section 1121 and a vertical section 1122, which are connected to each other and arranged in an L shape, the horizontal section 1121 is used to be loaded above the fixed part 111, and the vertical section 1122 extends downward perpendicularly to the horizontal section 1121, so that in the bed form, the vertical section 1122 can be supported on the ground as a supporting point, thereby improving the bearing capacity and stability of the movable part 112, and in the sofa form, the vertical section 1122 can be attached to the end of the fixed part 111 and shield the fixed part 111, thereby improving the appearance and simplicity of the sofa bed body 1.

[0042] Preferably, in order to facilitate the movement of the movable part 112, the bottom of the vertical section 1122 is provided with a pulley 113 which can be in contact with the ground and is used to assist users in pushing the movable part 112, after use, the pulley 113 can be folded and hidden in the vertical section 1122, thereby improving the appearance of the sofa bed body 1.

[0043] The mode of shape switching of the sofa bed body 1 in the embodiment is achieved by the relative displacement of the movable part 112 and the fixed part 111, which is only a preferred implementation scheme for realizing the function conversion of the sofa bed body 1. It should be understood that, under the premise of ensuring the spatial coordination relationship between the sleep aid assembly 2 and the sofa bed body 1, the specific implementation mode of the shape switching process can have multiple equivalent alternative schemes, such as a telescopic bed body, a folding bed body or a combined and assembled bed body, etc. Regardless of the specific structural form, as long as the following core characteristics are met: maintaining the effective communication between the spray pipeline 23 and the sleep aid assembly 2 during the conversion between the sofa form and the bed form, ensuring the uniform diffusion of the sleep aid aerosol on the surface of the bed body 11, and realizing the coordinated operation of the furniture function and the sleep aid function, all of which belong to the equivalent technical features of the technical scheme of the present application.

[0044] Specifically, the sofa bed body 1 further comprises a backrest 12 and two armrests 13, the backrest 12 is arranged at one end of the fixed part 111 away from the movable part 112, and the armrests 13 are arranged on both sides of the fixed part 111. The inside of the armrests 13 and the inside of the backrest 12 are both provided with spray pipes 23. By arranging the armrests 13 and the backrest 12, places for users to lie down and place their arms are provided, and the comfort of users when sitting or lying down is improved. The inside of the armrests 13 and the inside of the backrest 12 are both provided with spray pipes 23, so that the sleep-aiding gas mist can cover the head, torso and arm contact areas of the user in a sitting or lying down state. When the sofa bed body 1 is in a sofa shape, the user's back leans against the backrest 12, and the arms are naturally placed on the armrests 13. At this time, the spray pipes 23 of the backrest 12 and the armrests 13 directly deliver the gas mist to the upper body core perception area of the human body, thereby strengthening the inhalation efficiency of the sleep-aiding gas mist. In the bed shape, the backrest 12 and the armrests 13 are located in the main supporting area of the head and torso of the user. The sleep-aiding gas mist released by the spray pipes 23 arranged in the backrest 12 and the armrests 13 can directly act on the oral and nasal perception area of the user, thereby realizing efficient absorption of the sleep-aiding gas mist.

[0045] More specifically, the spray pipes 23 located in the armrests 13 extend along the length direction of the armrests 13, so that the sleep-aiding gas mist can uniformly cover the arm placement area of the user, forming a local high-concentration sleep-aiding atmosphere. The spray pipes 23 located in the backrest 12 extend from the outer periphery to the center of the backrest 12, forming a plurality of annular pipe bodies. The plurality of annular pipe bodies are arranged in a spaced manner, and can diffuse the sleep-aiding gas mist in all directions with the center of the backrest 12 as the origin, so that the sleep-aiding gas mist can uniformly cover each area of the backrest 12, ensuring that the user can be surrounded by the sleep-aiding gas mist no matter where he lies. The arrangement of the plurality of annular pipe bodies arranged in a spaced manner provides multiple diffusion paths for the sleep-aiding gas mist, avoiding the problem of uneven distribution caused by the sleep-aiding gas mist concentrating in a certain area. The spray pipes 23 are provided with gas outlet holes 231, and a plurality of gas outlet holes 231 are arranged in a spaced manner along the extension direction of the spray pipes 23, thereby improving the uniformity of the sleep-aiding gas mist sprayed from the spray pipes 23.

[0046] Preferably, the backrest 12 and the fixed part 111 are connected by a rotating shaft structure, so that the backrest 12 can be flipped relative to the bed body 11 to adjust the angle of the backrest 12 to adapt to the needs of different users. A damping adjuster is arranged in the rotating shaft structure, so that the backrest 12 can be adjusted in a segmented manner within a range of 90 degrees to 120 degrees, thereby improving the adaptability of the sofa bed body 1 and meeting the needs of users of different sizes and in different scenes.

[0047] Preferably, the backrest 12 comprises a frame body 122 and a soft cushion 121, the soft cushion 121 is arranged on the frame body 122, the spray pipe 23 is arranged between the soft cushion 121 and the frame body 122, and a plurality of air-permeable through holes 1211 are arranged through the thickness of the soft cushion 121. When the sleep-aiding work is performed, the sleep-aiding aerosol generated is transported from the spray pipe 23, sprayed out through the air outlet hole 231, and uniformly permeates to the front of the soft cushion 121 through the air-permeable through holes 1211 of the soft cushion 121, forming a dispersion path from inside to outside. Since the soft cushion 121 is directly relied on by the user, the sleep-aiding aerosol diffused therefrom can directly act on the body contact area of the user. The interlayer space between the frame body 122 and the soft cushion 121 provides a concealed and stable installation environment for the spray pipe 23, which not only avoids deformation of the spray pipe 23 under pressure, but also ensures the sleep-aiding aerosol output efficiency through the vertical correspondence between the air-permeable through holes 1211 and the air outlet hole 231. In addition, the air-permeable through holes 1211 of the soft cushion 121 can maintain natural ventilation in the non-working state, without affecting the original air permeability and comfort of the soft cushion 121.

[0048] In the embodiment, the sofa bed body 1 adopts a double-unit symmetrical layout structure, that is, two groups of bed bodies 11 and backrests 12 are symmetrically arranged along the width direction, each group comprising one bed body 11 and a corresponding backrest 12 arranged at one end thereof, and one handrail 13 is arranged at the outer side of each of the two groups of bed bodies 11 and backrests 12, forming an expanded sofa bed body 1 that can be used by multiple people at the same time. One sleep-aiding assembly 2 is independently arranged inside each handrail 13, and forms two completely independent sleep-aiding systems with the spray pipe 23 inside the backrest 12 and the bed body 11 on the same side. Therefore, the user can select to start the sleep-aiding system on one side or both sides according to actual needs. When a single person uses it, the sleep-aiding system on one side can be selectively activated to reduce energy consumption. When multiple people use it but have different needs, the sleep-aiding system on any side can be selectively activated or closed according to individual needs, thereby improving the adaptability of the sofa bed body 1.

[0049] In other embodiments, a compact layout of a single group of bed bodies 11 and backrests 12 can also be adopted, and only one set of sleep-aiding system is arranged to meet the needs of a single person, which will not be described here.

[0050] The handrail 13 is provided with an installation space for installing the sleep-aiding assembly 2, and a door plate 15 is movably connected to the handrail 13. The door plate 15 is used to open or close the installation space. When the door plate 15 is closed, the installation space is closed, which can effectively prevent dust and sundries from entering, and can also hide the sleep-aiding assembly 2 in the sofa bed body 1, avoiding the influence on the overall appearance of the sofa bed body 1, and the door plate 15 is also hidden in the sofa bed body 1, so that the sofa bed body 1 remains simple and smooth in vision. When the door plate 15 is opened, the sleep-aiding assembly 2 in the installation space is exposed to the outside, so as to facilitate the maintenance and replacement of the sleep-aiding assembly 2 or the replenishment of the required consumables of the sleep-aiding assembly 2.

[0051] The excitation component is used to generate sleep-aiding aerosol and diffuse the sleep-aiding aerosol to the sofa bed body 1 through the spray pipeline 23 to achieve the sleep-aiding effect on the user.

[0052] Specifically, the excitation component includes a shell 21 for containing sleep-aiding liquid and an atomization mechanism 22 in communication with a liquid outlet 214 of the shell 21, the atomization mechanism 22 being used to atomize the sleep-aiding liquid into sleep-aiding aerosol, and the spray pipeline 23 being in communication with the atomization mechanism 22. The shell 21 forms a closed sleep-aiding liquid storage space, the sleep-aiding liquid is subjected to a particle treatment by the atomization mechanism 22 to generate sleep-aiding aerosol with sleep-aiding effect, the atomized sleep-aiding aerosol is delivered to various parts of the sofa bed body 1 through the spray pipeline 23 in communication therewith, and the three-dimensional diffusion effect is formed by the plurality of gas outlets 231 uniformly distributed on the surface of the spray pipeline 23, so that the sleep-aiding aerosol can be naturally diffused along the use surface of the sofa bed body 1.

[0053] Specifically, the shell 21 includes a liquid storage tank 211 for containing sleep-aiding raw liquid, a water storage tank 212 for containing pure water, the liquid storage tank 211 being in communication with a mixing tank 213 and capable of delivering the sleep-aiding raw liquid to the mixing tank 213, the water storage tank 212 being in communication with the mixing tank 213 and capable of delivering the pure water to the mixing tank 213, the mixing tank 213 having a liquid outlet 214, and the mixing tank 213 being used to mix the sleep-aiding raw liquid and the pure water to form sleep-aiding liquid and deliver the sleep-aiding liquid to the atomization mechanism 22 through the liquid outlet 214. By storing the sleep-aiding raw liquid and the pure water separately, the stability of the two can be ensured when not in use, and problems such as deterioration that may be caused by premature mixing can be avoided. Moreover, the sleep-aiding raw liquid and the pure water are mixed in the mixing tank 213, the proportion of the sleep-aiding raw liquid and the pure water can be flexibly adjusted according to actual needs, so as to control the concentration of the sleep-aiding liquid and meet the individual needs of different users for the intensity of sleep-aiding effect.

[0054] Further, a first control valve 24 is arranged between the liquid storage tank 211 and the mixing tank 213, the first control valve 24 being used to control the delivery amount of the sleep-aiding raw liquid; a second control valve 25 is arranged between the water storage tank 212 and the mixing tank 213, the second control valve 25 being used to control the delivery amount of the pure water.

[0055] Further, the mixing box 213 is provided with a concentration detector 26, which can control the first control valve 24 and the second control valve 25 to operate based on the concentration of the sleep-aiding liquid. In use, the user can pre-input a preset concentration value required by the concentration detector 26 in advance, and then control the first control valve 24 and the second control valve 25 to open, so that the sleep-aiding raw liquid and pure water are respectively delivered to the mixing box 213 and mixed to form the sleep-aiding liquid. At the same time, the concentration detector 26 detects the concentration of the sleep-aiding liquid in the mixing box 213 in real time. If it is detected that the concentration of the sleep-aiding liquid is too high, it means that the delivery amount of the sleep-aiding raw liquid is relatively excessive. At this time, the concentration detector 26 will issue an instruction to the first control valve 24 to reduce the opening degree, so as to reduce the delivery amount of the sleep-aiding raw liquid. At the same time, the opening degree of the second control valve 25 is increased to increase the delivery amount of pure water, so as to dilute the sleep-aiding liquid and make its concentration return to the preset range. Conversely, if it is detected that the concentration of the sleep-aiding liquid is too low, the concentration detector 26 will make the opposite control operation, i.e., increase the delivery amount of the sleep-aiding raw liquid and reduce the delivery amount of pure water, until the concentration of the sleep-aiding liquid in the mixing box 213 reaches the preset concentration value. After that, when the liquid level of the sleep-aiding liquid in the mixing box 213 reaches the preset liquid level, the first control valve 24 and the second control valve 25 are controlled to be completely closed to stop the injection process of the mixing box 213.

[0056] Among them, the first control valve 24 and the second control valve 25 adopt an electromagnetic proportional valve structure, the opening degree of the valve core thereof is in linear relationship with the input current, for real-time adjustment of the delivery flow. The concentration detector 26 detects the density or other chemical properties of the sleep-aiding liquid through the built-in sensor, so as to judge the concentration of the sleep-aiding liquid. Those skilled in the art understand the specific structure and working principle thereof, which will not be described here.

[0057] In the embodiment, the sleep-aiding raw liquid is preferably a fragrance essential oil, which is converted into a fragrance aerosol with a soothing nerve effect by the atomization mechanism 22. It should be understood that the above-mentioned specific selection of the fragrance essential oil is only exemplary, and in actual implementation process, the sleep-aiding raw liquid can also be replaced by an atomized solution containing a melatonin component, a traditional Chinese medicine extract liquid with a tranquilizing effect, or other volatile liquids capable of producing a sleep-aiding effect through olfactory nerve stimulation or skin contact absorption. It should be particularly noted that the specific material composition of the sleep-aiding raw liquid is not uniquely limited by the technical solution, and any chemical substance or composite preparation capable of producing a sleep-aiding effect through liquid atomization belongs to the equivalent replacement category of the sleep-aiding liquid mentioned in the utility model.

[0058] The atomization mechanism 22 is used to realize the atomization effect of the sleep-aiding liquid, and specifically, the atomization mechanism 22 comprises an atomization box 221, a piezoelectric ceramic transducer 222 and a vibrating component 223, the inlet of the atomization box 221 is communicated with the liquid outlet 214, the outlet of the atomization box 221 is communicated with the spray pipeline 23, the piezoelectric ceramic transducer 222 is connected with the vibrating component 223, the vibrating component 223 is connected with the atomization box 221, and the piezoelectric ceramic transducer 222 can drive the vibrating component 223 to vibrate so as to break the sleep-aiding liquid to form sleep-aiding aerosol.

[0059] In addition, the atomization mechanism 22 further comprises an ultrasonic control box 225, the ultrasonic control box 225 is electrically connected with the piezoelectric ceramic transducer 222, and in use, the ultrasonic control box 225 can generate high-frequency ultrasonic signals to be converted into high-frequency mechanical vibration through the piezoelectric ceramic transducer 222, so as to provide an energy source for atomization and to conduct the vibration to the vibrating component 223 to realize the atomization process.

[0060] Preferably, an amplitude transformer 224 is arranged between the piezoelectric ceramic transducer 222 and the vibrating component 223, and the amplitude transformer 224 can adjust the vibration amplitude generated by the piezoelectric ceramic transducer 222 according to actual needs. The smaller vibration amplitude can be amplified to make the vibrating component 223 obtain more suitable vibration intensity, so as to more effectively drive the atomization box 221 to vibrate and improve the atomization effect of the sleep-aiding liquid, or the excessive vibration amplitude can be reduced to avoid damage to the components of the atomization mechanism 22 due to too violent vibration and prolong the service life of the equipment.

[0061] The vibrating component 223 can be selected from a metal diaphragm, a ceramic vibrator or a rubber vibrating sheet, which is not limited herein.

[0062] It should be noted that the ultrasonic control box 225, the piezoelectric ceramic transducer 222 and the amplitude transformer 224 involved in the present application belong to the conventional technical means that can be understood and implemented by those skilled in the art. The core innovation point of the technical scheme of the present application is to integrate the sleep-aiding assembly 2 in the sofa bed main body 1 to realize the sleep-aiding effect of the sofa bed main body 1, and therefore the conventional technical contents such as the underlying operation details of the ultrasonic control box 225, the piezoelectric ceramic transducer 222 and the amplitude transformer 224 will not be described herein.

[0063] In order to be able to effectively deliver the sleep-aiding aerosol generated in the atomization box 221 to the spray pipeline 23, an output nozzle 226 is arranged between the outlet of the atomization box 221 and the spray pipeline 23, and the output nozzle 226 is used to deliver the sleep-aiding aerosol to the spray pipeline 23. Specifically, the output nozzle 226 comprises, in sequence from the input end to the output end, a conical pipe section, a steady flow cavity and a gradually expanding pipe section. The inlet of the conical pipe section is connected to the outlet of the atomization box 221 by a flange, and the inner surface of the conical pipe section is provided with a spiral flow guide groove; the steady flow cavity is a cylindrical cavity, and three flow guide vanes are arranged in the steady flow cavity, and the three flow guide vanes are uniformly distributed at an angle of 120 degrees in the circumferential direction; the outlet of the gradually expanding pipe section is connected to the inlet of the spray pipeline 23 by a sealing ring. When the sleep-aiding aerosol enters the nozzle from the outlet of the atomization box 221, the gradually tapering structure of the conical pipe section causes the airflow velocity to increase, and at the same time the spiral flow guide groove induces the sleep-aiding aerosol to generate rotational flow; after entering the steady flow cavity, the sleep-aiding aerosol is driven to flow through the gradually expanding pipe section by the flow guide vanes, and finally enters the spray pipeline 23.

[0064] In order to further improve the convenience of the sleep-aiding assembly 2, the sofa bed body 1 is provided with an armrest 13, and a control panel 14 is arranged on the armrest 13. The control panel 14 is electrically connected to the sleep-aiding assembly 2, and is used to control the operation of the sleep-aiding assembly 2.
