Description

Technical Field

[0001] The invention relates to the technical field of indoor air treatment, and in particular to an indoor fresh air humidification system. Background Art

[0002] The indoor fresh air humidification system is an advanced equipment that integrates fresh air ventilation and humidification functions. It can effectively improve the quality and humidity of indoor air and provide residents with a more comfortable and healthy living environment. In winter, especially after heating in northern regions, indoor air often becomes abnormally dry, which not only affects human comfort, but may also have an adverse effect on respiratory health. At the same time, when using heating equipment in southern regions, they often face the problem of reduced indoor humidity. In addition, in winter, due to closed doors and windows, indoor air circulation is poor, which can easily cause air pollution. For example, the concentration of harmful substances such as formaldehyde and TVOC may increase. At this time, the role of the fresh air humidification integrated machine is particularly important. It can not only introduce fresh air from outdoors, discharge indoor dirty air, and realize effective exchange of indoor and outdoor air, but also adjust indoor humidity at the same time and keep the air moist, thereby effectively alleviating the problems of indoor dryness and air pollution in winter, allowing residents to enjoy warmth while also having a fresh, moist and healthy indoor air environment.

[0003] But water contains calcium Ca 2+ , magnesium Mg 2+ When water is atomized, these ions will form water-insoluble carbonates such as CaCO3, MgCO3 or sulfate precipitation after the water evaporates, and adhere to the inner wall of the pipe. After long-term use, the inner wall of the uncleaned pipe will form layers of hard scale, which will not only cause the metal products in the pipe to rust, but also breed bacteria and cause respiratory infections. Therefore, an indoor fresh air humidification system is urgently needed. Summary of the invention

[0004] The object of the present invention is to provide an indoor fresh air humidification system to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an indoor fresh air humidification system, comprising a ventilation mechanism, wherein a humidification mechanism is arranged on the left side of the ventilation mechanism;

[0006] The ventilation mechanism comprises a shell one, a surface of the shell one is provided with a card slot one, an inner wall of the card slot is slidably connected with a primary filter screen, a surface of the shell one is provided with a card slot two, an inner wall of the card slot two is slidably connected with a high-efficiency filter screen, the surface of the shell one is fixedly connected with a limiting frame two, an inner wall of the limiting frame two is fixedly connected with a spring, an end of the spring away from the limiting frame two is fixedly connected with a card block, a surface of the card block is slidably connected with the limiting frame two, a side surface of the card block close to the spring is fixedly connected with a pull ring, the inner wall of the shell one is fixedly connected with the limiting frame one, the inner wall of the limiting frame one is slidably connected with the primary filter screen, and the inner wall of the limiting frame one is slidably connected with the high-efficiency filter screen;

[0007] The humidifying mechanism includes a shell three, the inner wall of the shell three is fixedly connected to a support frame two, the end of the support frame two away from the shell three is fixedly connected to a second motor, the output end of the second motor is fixedly connected to a rotating rod, the surface of the rotating rod away from the second motor is fixedly connected to a driving ring, the surface of the rotating rod is rotatably connected to a driving rod, the surface of the driving rod is fixedly connected to a driving block, the inner wall of an end of the driving rod away from the rotating rod is rotatably connected to a linkage rod, the end of the linkage rod away from the driving rod is rotatably connected to a knocking block, the knocking block penetrates the shell three and is slidably connected to the shell three, the humidifying mechanism also includes a shell two, the inner wall of the shell two is fixedly connected to a PTC humidifier.

[0008] The top of the shell 2 is fixedly connected to the shell 3, the left side of the shell 2 is fixedly connected to a gas pipeline, and the surface of the gas pipeline is fixedly connected to a buffer sleeve.

[0009] A water inlet pipe is arranged at the rear side of the PTC humidifier, and a heat-resistant drain pipe is arranged at the front side of the PTC humidifier.

[0010] An air inlet is provided on the right side of the shell one, a connecting hose is fixedly connected to the left side of the shell one, and one end of the connecting hose away from the shell one is fixedly connected to the shell two.

[0011] The inner wall of the shell 1 is fixedly connected with a support frame 1, and the top of the support frame 1 is fixedly connected with a mounting plate.

[0012] A first motor is fixedly connected to the surface of the mounting plate, and an output end of the first motor passes through the mounting plate and is fixedly connected to an impeller.

[0013] A first groove is provided on the surface of the primary filter screen, a second groove is provided on the surface of the high-efficiency filter screen, the inner wall of the first groove is engaged with a clamping block, and the inner wall of the second groove is engaged with a clamping block.

[0014] The surface of the housing 1 is fixedly connected to a limiting block.

[0015] The water inlet pipe passes through the second shell and extends to the outside of the second shell, and the heat-resistant drain pipe passes through the second shell and extends to the outside of the second shell.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] First, when the present invention is in use, the first motor in the ventilation mechanism drives the impeller to suck external air into the ventilation mechanism, and the sucked air is filtered by the primary filter and the high-efficiency filter, and then sent to the humidification mechanism through the connecting hose. The water inlet pipe sends water to the PTC humidifier, and the PTC humidifier uses PTC to heat and evaporate the water to humidify the sucked air, and then it is transported to the room through the gas pipeline to complete the air humidification.

[0018] Second, when the present invention is in use, the primary filter and the high-efficiency filter can be very conveniently inserted into the designated position through the card slot 1 and the card slot 2 on the ventilation mechanism. When the filter is inserted, its edge will contact the card block, and as the insertion depth gradually increases, the filter itself will press the card block, so that the spring is compressed and shrinks inward. This design cleverly utilizes the elastic characteristics of the spring to provide a buffer and adaptive space for the installation of the filter. When the filter is inserted to the bottom, the card block expands outward under the elastic force of the spring. At this time, the card block just gets stuck in the groove 1 and the groove 2 opened on the surface of the primary filter and the high-efficiency filter, thereby achieving a stable fixation of the filter. This fixing method is both reliable and simple, and does not require additional tools or complicated operations. When the filter needs to be replaced, the user only needs to gently pull the pull ring to slide the card block outward to release the fixation of the filter, and then the primary filter and the high-efficiency filter can be easily taken out for replacement. This design greatly saves the time required for replacing the filter, improves the convenience and efficiency of use, and makes maintenance simpler and faster.

[0019] Third, when the present invention is in use, the humidified air will be transported to the room through the gas pipeline, and part of the water mist will remain in the pipeline. At this time, the second motor is started to drive the rotating rod to rotate, and the driving ring is driven to rotate by the rotating rod. When the driving ring rotates, it will resist the driving block of the driving rod, so that the driving rod is reset after rotating 180 degrees. While rotating, the linkage rod rotatably connected to the inner wall of the bottom end of the driving rod will be pulled, and at the same time, the knocking block rotatably connected to the bottom end of the linkage rod will be pulled. After rotating 180 degrees, the knocking block will fall and knock on the buffer sleeve on the surface of the summer pipeline, causing the gas pipeline to vibrate and shake off the water mist attached to the surface. By setting the inclination angle when setting the gas pipeline, the water stains inside can flow out through the pipeline, which solves the problem that after long-term use, the inner wall of the pipeline that has not been cleaned will form layers of hard scale layers, which will not only cause the metal products in the pipe to rust, but also breed bacteria and cause respiratory infections.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides the following technical solutions:

[0030] Embodiment 1

[0031] See also Figure 1-6 , an indoor fresh air humidification system, comprising a ventilation mechanism 1, a humidification mechanism 2 is arranged on the left side of the ventilation mechanism 1;

[0032] The ventilation mechanism 1 includes a shell 10, a slot 1 is provided on the surface of the shell 10, a primary filter 1002 is slidably connected to the inner wall of the slot, a slot 2 is provided on the surface of the shell 10, a high-efficiency filter 1003 is slidably connected to the inner wall of the slot 2, the surface of the shell 10 is fixedly connected to a limiting frame 2 1009, a spring 1010 is fixedly connected to the inner wall of the limiting frame 1009, a block 1011 is fixedly connected to one end of the spring 1010 away from the limiting frame 1009, a surface of the block 1011 is slidably connected to the limiting frame 1009, a pull ring 1012 is fixedly connected to the surface of the block 1011 on one side close to the spring 1010, the inner wall of the shell 10 is fixedly connected to the limiting frame 1006, the inner wall of the limiting frame 1006 is slidably connected to the primary filter 1002, and the inner wall of the limiting frame 1006 is slidably connected to the high-efficiency filter 1003.

[0033] The primary filter 1002 and the high-efficiency filter 1003 can be easily inserted into the designated positions through the card slots 1 and 2 on the ventilation mechanism 1. When the filter is inserted, its edge will contact the card block 1011, and as the insertion depth gradually increases, the filter itself will press the card block 1011, so that the spring 1010 is compressed and shrinks inward. This design cleverly utilizes the elastic characteristics of the spring 1010 to provide a buffer and adaptive space for the installation of the filter. When the filter is inserted to the bottom, the card block 1011 expands outward under the elastic force of the spring 1010. At this time, the card block 1011 It just fits into the groove 1 and groove 2 on the surface of the primary filter 1002 and the high-efficiency filter 1003, thereby firmly fixing the filter. This fixing method is both reliable and simple, and does not require additional tools or complicated operations. When the filter needs to be replaced, the user only needs to gently pull the pull ring 1012 to slide the card block 1011 outward to release the fixation of the filter, and then the primary filter 1002 and the high-efficiency filter 1003 can be easily taken out for replacement. This design greatly saves the time required for replacing the filter, improves the convenience and efficiency of use, and makes maintenance easier and faster.

[0034] An air inlet 1001 is opened on the right side of the shell 10 , and a connecting hose 1014 is fixedly connected to the left side of the shell 10 . The end of the connecting hose 1014 away from the shell 10 is fixedly connected to the shell 2 20 .

[0035] Through the above technical solution, the air inlet 1001 of the housing 10 inhales air, which is then transported to the housing 2 20 through the connecting hose 1014 for humidification treatment after being filtered.

[0036] A groove 1 is formed on the surface of the primary filter 1002 , and a groove 2 is formed on the surface of the high efficiency filter 1003 . The inner wall of the groove 1 is engaged with the block 1011 , and the inner wall of the groove 2 is engaged with the block 1011 .

[0037] Through the above technical solution, the grooves on the primary filter 1002 and the high-efficiency filter 1003 are engaged with the clamping block 1011, so that the filter is firmly fixed in the ventilation mechanism 1.

[0038] The surface of the housing 10 is fixedly connected to a limiting block 1013 .

[0039] Through the above technical solution, the filter is limited.

[0040] Embodiment 2

[0041] See also Figure 1-7 , an indoor fresh air humidification system, the humidification mechanism 2 includes a shell 3 2005, the inner wall of the shell 3 2005 is fixedly connected with a support frame 2006, the end of the support frame 2006 away from the shell 3 2005 is fixedly connected with a second motor 2007, the output end of the second motor 2007 is fixedly connected with a rotating rod 2008, the surface of the end of the rotating rod 2008 away from the second motor 2007 is fixedly connected with a driving ring 2009, and the surface of the rotating rod 2008 is rotatably connected with a driving ring Rod 2010, a driving block 2011 is fixedly connected to the surface of the driving rod 2010, a linkage rod 2012 is rotatably connected to the inner wall of one end of the driving rod 2010 away from the rotating rod 2008, a knocking block 2013 is rotatably connected to the end of the linkage rod 2012 away from the driving rod 2010, the knocking block 2013 passes through the outer shell three 2005 and is slidably connected to the outer shell three 2005, the humidifying mechanism 2 also includes an outer shell two 20, and a PTC humidifier 2001 is fixedly connected to the inner wall of the outer shell two 20.

[0042] Through the above technical solution, the humidified air is smoothly transported to the room through the gas pipeline 2004, bringing pleasant humidity to the living environment. However, in this process, some fine water mist will inevitably stay on the inner wall of the gas pipeline 2004. In order to effectively remove the water mist and prevent it from accumulating for a long time to form a hard scale layer, the system is cleverly designed with a knocking device. When the pipeline needs to be cleaned, the second motor 2007 is started, which will drive the rotating rod 2008 to start rotating. The rotation of the rotating rod 2008 further drives the driving ring 2009 fixed thereon to rotate. During the rotation, the driving ring 2009 will abut against the driving block 2011 on the driving rod 2010. Through this abutment, the driving rod 2010 is rotated one hundred and eighty degrees after being acted upon by a force, and then reset under the action of the mechanical structure. During this rotation, the linkage rod 212 connected to the inner wall of the bottom end of the driving rod 2010 is pulled, and the linkage rod 2012 also pulls the knocking block 2013 connected to its bottom end at the same time. Driven by the linkage rod 2012, the knocking block 2013 also rotates 180 degrees and then falls, and powerfully knocks on the buffer sleeve 2014 on the surface of the gas pipeline 2004. This knocking action causes the gas pipeline 2004 to vibrate, shaking off the water mist attached to the inner wall. In addition, the gas pipeline 2004 is specially designed with an inclination angle when it is designed to ensure that the shaken-off water stains can flow out along the pipeline 2004 to avoid accumulation in the pipeline. This design effectively solves the problem of layers of hard scale formed on the inner wall of the pipeline due to the accumulation of water mist after long-term use. These scale layers will not only cause the metal products in the pipe to rust and reduce the service life of the pipe, but may also breed bacteria and cause health problems such as respiratory infections. Through this innovative knocking device and inclination design, the system ensures the cleanliness and hygiene of the gas pipeline and provides users with a healthier and more comfortable living environment.

[0043] The top of the second shell 20 is fixedly connected to the third shell 2005 , the left side of the second shell 20 is fixedly connected to the gas pipeline 2004 , and the surface of the gas pipeline 2004 is fixedly connected to the buffer sleeve 2014 .

[0044] A water inlet pipe 2003 is provided on the rear side of the PTC humidifier 2001 , and a heat-resistant drain pipe 2002 is provided on the front side of the PTC humidifier 2001 .

[0045] Through the above technical solution, the water inlet pipe 2003 continuously transports water to the PTC humidifier 2001. The PTC humidifier 2001 uses the heating effect of the PTC element to quickly evaporate the water into water vapor, which is fully mixed with the incoming air to humidify the air. The remaining liquid will be discharged from the heat-resistant drain pipe 2002.

[0046] The water inlet pipe 2003 penetrates the second shell 20 and extends to the outside of the second shell 20 , and the heat-resistant drainage pipe 2002 penetrates the second shell 20 and extends to the outside of the second shell 20 .

[0047] By using the above technical solution, moisture will not stay in the device.

[0050] Through the above technical solution, the installation of the internal first motor 1004 is achieved.

[0051] The first motor 1004 is fixedly connected to the surface of the mounting plate 1005 , and the output end of the first motor 1004 passes through the mounting plate 1005 and is fixedly connected to the impeller 1008 .

[0052] Through the above technical scheme, when in use, after the system is started, the first motor 1004 in the ventilation mechanism 1 starts to run, driving the impeller 1008 to rotate at a high speed, generating a strong suction force, and sucking the external fresh air into the ventilation mechanism 1. The air first passes through the primary filter 1002 to filter out large particles of dust and impurities, and then passes through the high-efficiency filter 1003 to further remove tiny particles to ensure that the inhaled air is fresh and clean. The filtered air is then transported to the humidification mechanism 2 through the connecting hose 1014. At this time, the water inlet pipe 2003 continuously transports moisture to the PTC humidifier 2001. The PTC humidifier 2001 uses the heating effect of the PTC element to quickly evaporate the moisture into water vapor, which is fully mixed with the incoming air to humidify the air. Finally, the humidified air is transported to the room through the gas pipeline 2004, providing a suitable air humidity for the living environment, completing the air humidification process, and creating a more comfortable and pleasant living environment.
