DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 The technical solution of the utility model is further illustrated by specific implementation methods.

[0031] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, which can be said to be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] An air purifier with a lifting function, comprising a base 1, a first shell 2, a second shell 3, a lifting device 4, a dust sensor 5 and an air purifying device 6;

[0034] The first housing 2 is vertically installed above the base 1, and the dust sensor 5 and the lifting device 4 are respectively installed in the first housing 2; the detection end of the dust sensor 5 passes through the side wall of the first housing 2 and inputs the indoor air; the moving end of the lifting device 4 passes through the side wall of the first housing 2 and is connected to the second housing 3;

[0035] The outer circumference of the first housing 2 is provided with a plurality of scale lines 21, and the plurality of scale lines 21 respectively represent different levels of air quality; the air purification device 6 is installed in the second housing 3, and the air purification device 6 is used for indoor air;

[0036] The lifting device 4 and the air purification device 6 are respectively connected to the dust sensor 5 signal, and the dust sensor 5 is used to detect the current indoor air quality index; the lifting device 4 drives the first shell 2 to move above the base 1, and raises the bottom surface of the first shell 2 to be flush with the scale line 21 corresponding to the level of the current indoor air quality index.

[0037] Figure 1-3 It is a structural schematic diagram of the air purifier with lifting function of the utility model.

[0038] The dust sensor 5 has the characteristics of small size, light weight and easy installation. The dust sensor 5 has an airflow generator built in it, which can attract external air by itself. The dust sensor 5 detects dust particles larger than 1 micron through a beam of parallel monochromatic light. After the parallel monochromatic light irradiates these dust particles, scattering phenomenon will occur, and these dust particles will also absorb part of the light energy. By detecting and calculating the relative attenuation rate of light intensity, the relative concentration of dust in the indoor air can be obtained, thereby knowing the indoor air quality index level.

[0039] The air quality levels represented by the multiple scale lines 21 correspond one to one with the air quality index levels in the "HJ 633-2012 Technical Regulations on Ambient Air Quality Index (AQI)", as shown in the table below.

[0040]

[0041] When the air purifier with lifting function of the utility model is turned on, the dust sensor 5 starts and detects the indoor air. The dust sensor 5 converts the detection result (the instant indoor air quality index level) into an electrical signal and transmits it to the lifting device 4 and the air purification device 6. The lifting device 4 starts and drives the second shell 3 and the air purification device 6 to move upward to the height of the scale line 21 corresponding to the instant indoor air quality level according to the received signal, so that the bottom surface of the second shell 3 is flush with the corresponding scale line 21. If the current air quality index level is not level one, the air purification device 6 starts and purifies the indoor air until the air quality index level reaches level one. During the air purification process, the dust sensor 5 detects the indoor air quality in batches according to the set interval time, and the lifting device 4 adjusts the height of the bottom surface of the second shell 3 according to the signal sent by the dust sensor 5 received each time.

[0042] The user can understand the instant indoor air quality status by observing the scale lines 21 corresponding to the bottom surface of the second shell 3 and the height change of the second shell 3 .

[0043] Furthermore, an indicator light 31 is installed at the bottom of the second housing 3;

[0044] The indicator light 31 surrounds the bottom of the inner wall of the second shell 3;

[0045] The indicator light 31 is connected to the dust sensor 5 by signal. The indicator light 31 can display multiple colors. The color displayed by the indicator light 31 corresponds to the same color representing the air quality index level measured instantly by the dust sensor 5.

[0046] like Figure 1 As shown, the dust sensor 5 converts the detection result into an electrical signal and transmits it to the indicator light 31. The indicator light 31 corresponds to the color representing the air quality index level in the "HJ 633-2012 Technical Regulations on Ambient Air Quality Index (AQI)". By observing the color of the indicator light 31, the user can intuitively know the current indoor air quality status.

[0047] Specifically, the lifting device 4 includes a lifting assembly 41, a connecting plate 42 and a guide bracket 43;

[0048] The first shell 2 is provided with a guide groove 23; the guide groove 23 is located on the side wall of the first shell 2 close to the second shell 3, and the guide groove 23 extends in a direction perpendicular to the top surface of the base 1;

[0049] The bottom end of the guide bracket 43 is installed on the bottom of the first shell 2, and the guide bracket 43 is arranged upright; the lifting component 41 can be slidably mounted on the guide bracket 43; one end of the connecting plate 42 is mounted on the top of the lifting component 41, and the other end of the connecting plate 42 passes through the guide groove 23 and the second shell 3 in sequence and is fixed to the inner wall surface of the second shell 3; the other end of the connecting plate 42 is the moving end of the lifting device 4.

[0050] like Figure 1 As shown, the lifting assembly 41 pushes the connecting plate 42 to move up and down along the guide bracket 43 and the guide groove 23, thereby driving the air purification device 6 to rise and fall along with the second housing 3.

[0051] Furthermore, the air purification device 6 includes a filter element 61 and an exhaust fan 62;

[0052] The second housing 3 is provided with an air inlet grille 32 and an air outlet grille 33;

[0053] The air inlet grille 32 is located on the bottom surface of the second housing 3, and the air outlet grille 33 is located on the top surface of the second housing 3;

[0054] The output end of the filter element 61 is connected to the input end of the exhaust fan 62, and the input end of the filter element 61 inputs indoor air through the air inlet grille 32. The output end of the exhaust fan 62 is connected to the air outlet grille 33 and outputs purified air.

[0055] like Figure 1 As shown, the indoor air to be purified is sucked in from the bottom of the second shell 3 through the filter element 61 and the exhaust fan 62, and the purified air is output from the top of the second shell 3. The air purification device 6 continuously circulates and purifies the indoor air until the indoor air quality index reaches the first level.

[0056] Preferably, the outer peripheral surface of the other end of the connecting plate 42 is fixed to the inner wall surface of the second shell 3 , and the top surface of the connecting plate 42 abuts against the bottom surface of the exhaust fan 62 .

[0057] like Figure 1 As shown, the lifting device 4 is moved by the connecting plate 42 while supporting the weight of the air purification device 6, so as to ensure the operation stability of the air purification device 6 during the movement.

[0058] Furthermore, the first housing 2 is also provided with a plurality of buttons 22;

[0059] The plurality of buttons 22 are respectively located on the top surface of the first housing 2 .

[0060] like Figure 3As shown, a plurality of buttons 22 may be respectively arranged at the edge of the top surface of the first housing 2 , and the on and off of the power supply or the start and stop of the dust sensor 5 may be controlled by the corresponding buttons 22 .

[0061] Preferably, the corresponding air quality index levels represented by the multiple scale lines 21 arranged from low to high increase successively.

[0062] For example, the six scale lines 21 arranged from low to high represent the corresponding air quality index levels of level 1, level 2, ..., level 5 and level 6, respectively.

[0063] When the indoor air quality index level is level one, that is, the air quality is excellent, the bottom surface of the second shell 3 abuts against the top surface of the base 1, and the air purification device 6 stops working. Figure 1 The state of the air purifier with lifting function.

[0064] The worse the indoor air quality is, the larger the distance between the bottom surface of the second shell 3 and the top surface of the base 1 is, which is conducive to the air inlet grille 32 to quickly input the indoor air to be purified from the bottom surface of the second shell 3 and the top surface of the base 1. Figure 2 and Figure 3 The air purifier with lifting function shown is in the worst air quality state.

[0065] In summary, if Figure 1-3 In the embodiment of the utility model shown, the air purifier with a lifting function adjusts the height position of the second shell 3 and the corresponding scale line 21 according to the detection result of the dust sensor 5 and through the lifting device 4 to indicate the indoor air quality status and change information, so as to improve the convenience for users to obtain relevant information.

[0066] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
