Description

Technical Field

[0001] This utility model belongs to the field of fresh air system technology, and specifically relates to an air outlet terminal of a fresh air system. Background Technology

[0002] As people's requirements for indoor air quality and comfort continue to increase, fresh air systems are being used more and more widely in various types of buildings.

[0003] Traditional fresh air outlets are mostly located high on the wall or on the ceiling, which can easily cause temperature stratification in the room. When the fresh air travels from the main unit through a long duct to the outlet, both the air velocity and heat are lost. In addition, the fresh air outlet has a single function and cannot meet people's diverse needs. Utility Model Content

[0004] The purpose of this utility model is to provide an air outlet terminal for a fresh air system, so as to solve the technical problems of existing fresh air systems that cause indoor temperature stratification, and the inability of fresh air velocity and heat to meet people's requirements during delivery, as well as the single function.

[0005] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0006] This utility model discloses an air outlet terminal of a fresh air system, including a concealed housing. The housing has an air supply channel with a valve interface and an air outlet at each end. The valve interface is connected to a fresh air duct, and the air outlet is opposite to the baseboard. The housing contains an electrical control mechanism and a main fan, a heating mechanism, a humidifying mechanism, and an aromatherapy mechanism electrically connected to the electrical control mechanism. The main fan and the heating mechanism are located at the end of the valve interface along the fresh air direction. The electrical control mechanism is connected to a wireless communication component.

[0007] The beneficial effects of this invention are at least as follows: The box contains an air supply channel. A valve interface at one end of the air supply channel receives fresh air supplied by the fresh air duct, and an air outlet at the other end outputs fresh air. The box contains an electrical control mechanism, a main fan, a heating mechanism, a humidification mechanism, and an aromatherapy mechanism. Users can control the operation of the main fan and other mechanisms via the electrical control mechanism. When the output air velocity is low, the main fan can be turned on to increase the output air velocity. When the output air temperature is low, the heating mechanism can be turned on to increase the temperature of the fresh air. When the indoor humidity is low, the humidification mechanism can be turned on to maintain a suitable humidity level, preventing dry skin and respiratory discomfort. The aromatherapy mechanism can be turned on to add fragrance to the fresh air, freshening the indoor air or masking odors, thus improving the comfort of the indoor environment.

[0008] The electrical control mechanism is connected to a wireless communication component, allowing people to control the opening and closing of mechanisms such as the main fan via wireless signals sent by electronic devices.

[0009] The concealed design of the enclosure allows the air outlet of the fresh air system to blend seamlessly with the interior décor. With the air outlet aligned with the baseboard, when delivering warm fresh air, the air flows from bottom to top, ensuring a uniform temperature between the upper and lower layers of the indoor environment and preventing temperature stratification.

[0010] As a further improvement to the above technical solution, the air outlet of the box is a funnel shape that increases in size along the fresh air direction, and the larger end of the box is connected to a first cover plate, which is divided into multiple air outlets.

[0011] As a further improvement to the above technical solution, the air supply channel is provided with multiple inclined air guide plates.

[0012] As a further improvement to the above technical solution, the air inlet end of the box extends vertically and is connected to a second cover plate, and the air valve interface is located in the middle of the second cover plate.

[0013] As a further improvement to the above technical solution, the humidification mechanism and the aromatherapy mechanism are located at opposite ends of the main fan along the extension direction of the second cover plate.

[0014] As a further improvement to the above technical solution, a partition is provided inside the box, and the partition is located between the humidification mechanism and the main fan and the heating mechanism.

[0015] As a further improvement to the above technical solution, the aromatherapy mechanism includes a detachable aromatherapy bottle, which is opposite to the air outlet. The box is also provided with a lifting mechanism, the output end of which is connected to the aromatherapy mechanism, so that the aromatherapy bottle extends out of the air outlet.

[0016] As a further improvement to the above technical solution, the lifting mechanism includes an upper limit switch and a lower limit switch, and the electrical control mechanism is electrically connected to the lifting mechanism, the upper limit switch and the lower limit switch respectively.

[0017] As a further improvement to the above technical solution, the second cover plate is detachably connected to a filter screen, and the filter screen is provided with a replacement hole corresponding to the aromatherapy bottle.

[0018] As a further improvement to the above technical solution, the humidification mechanism includes a water inlet valve, a water tank, an atomizing nozzle, a small fan, and a water level control component. The electrical control mechanism is electrically connected to the water inlet valve, the atomizing nozzle, the small fan, and the water level control component, respectively.

[0039] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0040] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] In the description of this utility model, the use of terms such as "several" means one or more, with "multiple" meaning two or more. Terms like "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of terms like "first," "second," and "third" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the quantity of indicated technical features, or the sequential relationship between indicated technical features.

[0042] It should be noted that in the attached diagram, the X direction points from the rear to the front of the air outlet of the fresh air system; the Y direction points from the left to the right of the air outlet of the fresh air system; and the Z direction points from the bottom to the top of the air outlet of the fresh air system.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0044] In existing technologies, air outlets are generally located on the ceiling. When delivering warm fresh air, the warm fresh air, due to its lower density, accumulates at the top of the indoor space, resulting in a temperature stratification where the upper part is warm and the lower part is cold, which affects people's user experience.

[0045] Reference Figures 1 to 9 The following are several embodiments of the air outlet terminal of the fresh air system of this utility model.

[0046] like Figures 1 to 9 As shown, the air outlet 100 of the fresh air system in this embodiment includes a concealed housing 200. An air supply channel 210 is provided inside the housing 200. One end of the air supply channel 210 is provided with an air valve interface 410, which is used to connect to the fresh air duct and receive fresh air. The other end of the air supply channel 210 is provided with an air outlet 310, which is horizontally opposite to the baseboard 110. After passing through the air supply channel 210, the fresh air is delivered from the air outlet 310 to the indoor floor via the baseboard 110, effectively promoting natural convection of hot and cold air in the indoor space. The fresh air gradually fills the indoor space, effectively solving the temperature stratification problem caused by traditional air outlets 310, making the indoor temperature more balanced and the human body more comfortable.

[0047] It is understandable that the box 200 contains an electrical control mechanism 510, a main fan 520, a heating mechanism 530, a humidifying mechanism 800, and an aromatherapy mechanism 600. The electrical control mechanism 510 is electrically connected to the main fan 520, the heating mechanism 530, the humidifying mechanism 800, and the aromatherapy mechanism 600, respectively. People can control the opening and closing of the main fan 520 and other structures through the electrical control mechanism 510.

[0048] Understandably, the electrical control mechanism 510 is wired to a central control screen, allowing people to drive the electrical control mechanism 510 through the central control screen, thereby controlling the airflow speed, temperature, and quality of the fresh air.

[0049] Understandably, the electrical control mechanism 510 is connected to a wireless communication component, which can be Bluetooth, infrared, or WiFi, etc. People can send wireless signals via electronic devices, and the wireless communication component receives the wireless signals and sends them to the electrical control mechanism 510, thereby wirelessly controlling the opening and closing of structures such as the main fan 520.

[0050] In this embodiment, the main fan 520 and the heating mechanism 530 are located at the end of the air valve interface 410 along the fresh air direction.

[0051] It is understandable that when fresh air passes through the air valve interface 410 and enters the air supply channel 210, the air speed can be increased again by the main fan 520 to make up for the air speed loss of fresh air in the fresh air duct.

[0052] In this embodiment, the main fan 520 is a high-efficiency, low-noise fan with adjustable speed, allowing people to precisely adjust the airflow and speed of fresh air according to the actual needs of the room. When people are gathering in a crowded living room, the speed of the main fan 520 can be increased to increase the airflow and speed of fresh air and improve air convection; when people are sleeping in a quiet bedroom, the airflow and speed of fresh air can be reduced to deliver fresh air gently, ensuring that the air outlet terminal 100 of the fresh air system can provide just the right amount of fresh air supply in different scenarios, ensuring continuous air renewal and maintaining good indoor air quality.

[0053] Understandably, after the fresh air passes through the main fan 520 and then through the heating mechanism 530, the fresh air can be reheated by the heating mechanism 530 in cold weather to make up for the heat loss of the fresh air in the fresh air duct.

[0054] In this embodiment, the heating mechanism 530 is equipped with a PTC heating element that enables rapid heating and precise temperature control. During cold seasons, the heating mechanism 530 can provide auxiliary heating for fresh air, making the blown air warm and pleasant. This effectively avoids the overheating risk of traditional heating methods, is energy-saving and safe, and creates a warm and comfortable indoor environment for people. It also helps prevent seasonal colds among temperature-sensitive groups such as the elderly and children, thus improving the comfort of living in the home.

[0055] Understandably, the humidifier 800 is used to humidify the fresh air, which helps to replenish the moisture in the air in a timely manner during the dry autumn and winter seasons, preventing problems such as dry skin and respiratory discomfort caused by low air moisture, and keeping the indoor air within a suitable humidity range for the human body.

[0056] It is understood that the electronic control mechanism 510 or the humidification mechanism 800 can be electrically connected to the humidity sensor installed indoors. The electronic control mechanism 510 has a preset humidity, which allows the electronic control mechanism 510 to automatically control the opening and closing of the humidification mechanism 800 and adjust the humidification amount according to the data fed back by the indoor humidity sensor, so as to maintain the indoor humidity at the preset humidity.

[0057] Understandably, the aromatherapy unit 600 is used to refresh the air with pleasant scents, adding a delightful fragrance to the indoor air. People can choose different scents of aromatherapy liquid according to their preferences, making it easy to create a personalized and comfortable atmosphere, and enhance the quality of life and sense of ritual.

[0058] It is understandable that the end of the air supply channel 210 with the air valve interface 410 is the air inlet end of the box 200, and the end of the air supply channel 210 with the air outlet 310 is the air outlet end of the box 200.

[0059] Understandably, the air outlet of the box 200 is funnel-shaped, so that the air outlet of the box 200 is set from small to large along the fresh air direction, increasing the fresh air outlet 310, improving the indoor air circulation effect and air quality, and only increasing the air outlet 310, so that the laying of fresh air duct does not take up more installation space.

[0060] It is understandable that the smaller end of the air outlet of the box 200 is connected to the air inlet, and the larger end of the air outlet of the box 200 is provided with a first cover plate 300. The first cover plate 300 is divided into multiple air outlets 310, so that the fresh air output from the air supply channel 210 is diverted to multiple air outlets 310 for output, thereby increasing the output area of ​​the fresh air.

[0061] Understandably, since the air outlet 310 and the baseboard 110 are horizontally opposite each other, the box 200 is hidden inside the wall.

[0062] In some embodiments, the fresh air duct is laid along the ground, part of the box 200 is hidden in the ground, and the air valve interface 410 is located below the air outlet 310.

[0063] In this embodiment, the fresh air duct is laid along the wall, and the air valve interface 410 is located above the air outlet 310.

[0064] It is understood that the air supply duct 210 is provided with multiple air guide plates 220, which are arranged at intervals in the left and right direction. The two ends of the air guide plates 220 are connected to the front inner wall and the rear inner wall of the box body 200, respectively, so that an air supply branch pipe 230 is formed between two adjacent air guide plates 220 or between the air guide plate 220 and the inner wall of the box body 200. The air supply branch pipe 230 is opposite to the air outlet 310.

[0065] In this way, fresh air is delivered from the fresh air duct to the air supply channel 210 through the air valve interface 410, and then distributed to multiple air supply branch pipes 230 along the air supply channel 210, and then output from the air outlet 310 corresponding to the air supply branch pipe 230, so as to achieve uniform and gentle air supply.

[0066] In this embodiment, since the air outlet of the box 200 is trumpet-shaped, multiple air guide plates 220 are inclined to ensure that the fresh air output of each air outlet 310 is the same, making the fresh air output of multiple air outlets 310 more uniform.

[0067] Understandably, the air inlet of the housing 200 extends vertically, allowing fresh air to be stably delivered into the air inlet of the housing 200 through the air valve interface 410. One end of the air inlet of the housing 200 is connected to the smaller end of the air outlet of the housing 200, and the other end of the air inlet of the housing 200 is provided with a second cover plate 400. The air valve interface 410 is located on the second cover plate 400 to connect the air supply channel 210 and the fresh air duct.

[0068] In this embodiment, the second cover plate 400 extends in the left-right direction, and the air valve interface 410 is located in the middle of the second cover plate 400, so that fresh air is evenly delivered in the air supply channel 210.

[0069] It is understandable that, along the extension direction of the second cover plate 400, the humidification mechanism 800 and the aromatherapy mechanism 600 are respectively located at opposite ends of the main fan 520, so that the multiple structures in the box 200 are laid out reasonably. The humidification mechanism 800 and the aromatherapy mechanism 600 do not interfere with the delivery of fresh air. The fresh air output from the heating mechanism 530 can be diverted to the air supply branch pipe 230 along the air supply channel 210.

[0070] In this embodiment, since the main fan 520 and the heating mechanism 530 are laid vertically, the humidifying mechanism 800 is located to the left of the main fan 520 and the heating mechanism 530, and the aromatherapy mechanism 600 is located to the right of the main fan 520 and the heating mechanism 530.

[0071] Understandably, the housing 200 contains a partition 240 located between the humidification unit 800 and the main fan 520 and heating unit 530. The partition 240 separates the humidification unit 800 from the main fan 520 and heating unit 530, preventing water vapor output from the humidification unit 800 from entering the main fan 520 and heating unit 530 horizontally, or preventing water leakage from the humidification unit 800 that could lead to water ingress, electrical leakage, or malfunction in the main fan 520 and heating unit 530. The water vapor output from the humidification unit 800 is directly carried downwards by the fresh air and mixed with it.

[0072] Understandably, the aromatherapy device 600 includes a mounting base 610, an aromatherapy bottle 620, a generator 630, an air pump 640, and an air outlet pipe 650. Specifically, the generator 630 and the air pump 640 are fixed to the mounting base 610. The generator 630 is connected to the aromatherapy bottle 620, the air outlet pipe 650, and the air pump 640. When the aromatherapy device 600 is activated, the air pump 640 pumps the aromatherapy liquid into the generator 630, which atomizes the aromatherapy liquid. The atomized aromatherapy liquid is then output through the air outlet pipe 650 into the air supply channel 210, where it mixes with the fresh air inside the air supply channel 210, giving the output fresh air a fragrance.

[0073] It is understandable that the electronic control mechanism 510 is electrically connected to the generator 630 and the air pump 640 respectively, and the electronic control mechanism 510 controls the opening and closing of the generator 630 and the air pump 640.

[0074] Understandably, since the aromatherapy unit 600 is located to the right of the main fan 520 and the heating unit 530, the outlet of the air pipe 650 is set to the left so that the fresh air and the atomized aromatherapy liquid can be mixed evenly.

[0075] Understandably, the aromatherapy bottle 620 and the generator 630 are detachably connected, making it convenient for people to replace the aromatherapy bottle 620 with a new one when the aromatherapy liquid in the bottle is used up. It also makes it convenient for people to change the aromatherapy liquid with different scents according to their mood, season, or different usage scenarios, such as refreshing mint or soothing lavender.

[0076] Understandably, the aromatherapy bottle 620 and the air outlet 310 are positioned vertically opposite each other, allowing people to replace the aromatherapy bottle 620 through the air outlet 310.

[0077] In this embodiment, a lifting mechanism 700 is also provided inside the housing 200, and the output end of the lifting mechanism 700 is connected to the mounting base 610. Specifically, the lifting mechanism 700 includes a DC motor 710, a lead screw 720, and a nut seat 730. The lead screw 720 extends in the vertical direction, the output end of the DC motor 710 is connected to the lead screw 720, and the nut seat 730 is threaded onto the lead screw 720. The output end of the lifting mechanism 700 is the nut seat 730, that is, the nut seat 730 is connected to the mounting base 610.

[0078] Thus, when the lifting mechanism 700 is started, the DC motor 710 drives the lead screw 720 to rotate around the vertical axis, thereby causing the nut seat 730 to move the mounting seat 610 up and down, thereby realizing the overall up and down lifting of the aromatherapy mechanism 600, allowing the aromatherapy bottle 620 to pass through the air outlet 310 for easy replacement.

[0079] It is understood that the aromatherapy bottle 620 can be detached from the generator 630 via a snap-fit ​​or magnetic connection. In this embodiment, the aromatherapy bottle 620 and the generator 630 are connected by threads.

[0080] It is understood that the generator 630 and the air pump 640 are existing technologies of the aromatherapy mechanism 600. This utility model does not improve the structure of the generator 630 and the air pump 640. Therefore, those skilled in the art should understand the specific structure and working principle of the generator 630 and the air pump 640, which will not be explained in detail here.

[0081] Understandably, the DC motor 710 and the electronic control mechanism 510 are electrically connected. People only need to send commands to the electronic control mechanism 510 through the remote control or the software of the electronic device to make the electronic control mechanism 510 start the lifting mechanism 700, so that the aromatherapy bottle 620 can be smoothly extended out of the box 200. The operation is simple.

[0082] Furthermore, the lifting mechanism 700 is also equipped with an upper limit switch 741 and a lower limit switch 742 electrically connected to the electronic control mechanism 510, to limit the highest and lowest positions of the nut seat 730. Taking the lower limit switch 742 as an example, when the lowered nut seat 730 is connected to the lower limit switch 742, the lower limit switch 742 sends a signal to the electronic control mechanism 510, and the electronic control mechanism 510 shuts down the DC motor 710. At this time, the lower end of the aromatherapy bottle 620 extends out of the air outlet 310, and people can unscrew the aromatherapy bottle 620 at the air outlet 310.

[0083] Understandably, the second cover 400 is detachably connected to a filter 900, which can prevent mosquitoes and foreign objects from entering the housing 200, ensuring the hygiene and safety of the air outlet 100 of the fresh air system. The filter 900 has a replacement hole 910 corresponding to the aromatherapy bottle 620. When the lifting mechanism 700 lowers the aromatherapy mechanism 600, the aromatherapy bottle 620 passes through the air outlet 310 and the replacement hole 910, making it convenient for people to replace the aromatherapy bottle 620.

[0084] In this embodiment, the humidification mechanism 800 includes a water inlet valve 810, a water tank 820, an atomizing nozzle 830, a small fan 840, and a water level control component. The electrical control mechanism 510 is electrically connected to the water inlet valve 810, the atomizing nozzle 830, the small fan 840, and the water level control component.

[0085] Understandably, the water level control component includes a float 853, an upper magnetron 851, and a lower magnetron 852. The inlet valve 810 is connected to an external water supply pipe. When the inlet valve 810 is energized and opened, water flows into the water tank 820 along the supply pipe, gradually raising the water level. The float 853, being magnetic, rises with the water level. When the upper magnetron 851 senses the float 853, it sends a signal to the electronic control mechanism 510, which then closes the inlet valve 810. When the water level in the tank 820 decreases, if the lower magnetron 852 senses the float 853, it sends a signal to the electronic control mechanism 510, which then opens the inlet valve 810 to add water.

[0086] Understandably, when the electronic control mechanism 510 detects that the indoor humidity is too low, the electronic control mechanism 510 activates the atomizing nozzle 830 and the small fan 840. The atomizing nozzle 830 atomizes the liquid in the water tank 820 into water vapor, and the small fan 840 blows the water vapor into the box 200, where it mixes with the fresh air in the box 200 and is then blown out into the room by the main fan 520.

[0087] In this embodiment, the atomizing nozzle 830 is an ultrasonic atomizing head.

[0088] It is understandable that when reserving the installation location for the fresh air duct during renovation, a cavity of the same size as the box 200 is drilled in the wall in advance. When installing the fresh air duct, the box 200 is installed in the cavity, and the air valve interface 410 is connected to the fresh air duct, the water inlet valve 810 is connected to the water supply pipe, and then plastering and other decoration operations are carried out to hide the air outlet terminal 100 of the fresh air system.

[0089] Understandably, the skirting board 110 uses aluminum profiles and serves as an exterior component of the air outlet terminal of the fresh air system, thus serving both as a decorative element at the bottom of the wall and as a carrier for the air outlet.

[0090] In some embodiments, the baseboard 110 is vertically arranged, and the baseboard 110 corresponding to the air outlet 310 has ventilation holes. Therefore, the baseboard 110 covers the air outlet 310, and fresh air flows into the room through the air outlet 310 and the ventilation holes. However, the baseboard 110 needs to be removed to replace the aromatherapy bottle 620, which is inconvenient to use.

[0091] In this embodiment, the lower end of the second cover plate 400 is arc-shaped or inclined, so that the air outlet 310 is arc-shaped or inclined. The upper end of the baseboard 110 is provided with an opening 111. The second cover plate 400 and the air outlet 310 are hidden and embedded in the upper end of the baseboard 110. When the lifting mechanism 700 is activated, the aromatherapy bottle 620 extends out along the air outlet 310, the replacement hole 910 and the opening 111 of the baseboard 110, so that people can directly replace the aromatherapy bottle 620.

[0092] Understandably, the arc or inclined air outlet 310 can further expand the air outlet area, making the fresh air outlet more uniform.

[0093] It is understood that the electrical control mechanism 510 can be a microcontroller or a PCL controller, capable of simply controlling the main fan, heating mechanism, etc. It should be noted that the control method of the electrical control mechanism 510 is not within the scope of this utility model and belongs to existing technology. This utility model mainly protects the connection method of the electrical control mechanism 510.

[0094] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
