[0011] The air purified by the air purification component can be discharged from the first air outlet, and the second fan can inhale the purified air discharged from the first air outlet through the second air inlet and discharge it from the second air outlet.

[0012] Furthermore, the fuselage includes a base and a left panel, a rear panel, a right panel and a front panel arranged on the base in sequence, the left panel and the right panel are both provided with the first air inlet, and the two first air inlets are both provided with the filter; the first air outlet is located on the rear panel, and the shell is hinged on the left panel and the right panel.

[0013] Furthermore, a hinge hole is provided on the left side plate and the right side plate, and hinge parts are protruding on the left and right sides of the shell. The hinge part on the left side of the shell can be rotatably arranged in the hinge hole of the left side plate, and the hinge part on the right side of the shell can be rotatably arranged in the hinge hole of the right side plate.

[0014] Furthermore, the left side plate is provided with an arc-shaped slide groove on both sides of its own hinge hole, and the right side plate is also provided with an arc-shaped slide groove on both sides of its own hinge hole;

[0015] Two bosses are protruded from the left and right sides of the shell, wherein the two bosses on the left side of the shell can be slidably arranged in the two arc-shaped slide grooves of the left side plate, and the two bosses on the right side of the shell can be slidably arranged in the two arc-shaped slide grooves of the right side plate.

[0016] Furthermore, the centers of the two arc-shaped slide grooves on the left side panel coincide with the center of the hinge hole on the left side panel; the centers of the two arc-shaped slide grooves on the right side panel coincide with the center of the hinge hole on the right side panel.

[0017] Furthermore, the hinged portion includes a plurality of cylinders and a plurality of threaded columns with threaded holes which are arranged along the circumference of the inner wall of the hinged hole, and the cylinders and / or the threaded columns are movably pressed against the inner wall of the hinged hole.

[0018] Furthermore, the blowing assembly also includes a limiting cover, the limiting cover is provided with a plurality of through holes, and screws pass through the through holes and are connected to the threaded holes to fix the limiting cover on the threaded column.

[0019] Furthermore, a PTC heater is also provided in the shell, and the second fan can draw air at the second air inlet to the PTC heater for heating, and then discharge the air from the second air outlet.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the present invention, the overall module of the blowing assembly is rotatably arranged on the fuselage and located above the air purification assembly, so that the air inlet angle and the air outlet angle of the blowing assembly can be adjusted at the same time, which is equivalent to adjusting the upper and lower relative positions of the second air inlet relative to the first air outlet, thereby adjusting the blowing angle and adjusting the amount of air purified by the air purification assembly inhaled by the blowing assembly. Because the position of the first air outlet is arranged below the second air inlet, and the first air outlet is arranged to be tilted upward, the air purified by the air purification assembly is discharged from the first air outlet, inhaled from the second air inlet and discharged to the second air outlet, and then discharged to the person, when the second air inlet end of the blowing assembly is closer to the first air outlet, the amount of purified air inhaled by it is greater, when a large amount of purified air is to be discharged, the inclination angle of the blowing assembly can be increased to make the second air inlet closer to the position of the first air outlet; when the second air inlet end of the blowing assembly is farther from the first air outlet, the amount of purified air inhaled by it is less; and the diversification of the blowing mode is realized. In the shell of the blowing component, a PTC heater can be installed to act as a heater. Compared with general heating components, the PTC heater does not emit yellow light and is more comfortable to use. Since the air purification component and the blowing component in this structure are independent modules, the air purification function and the cold air and warm air fan functions can work together, and the air purification function and the cold air and warm air fan functions can work independently. When a single function is damaged, it does not affect the normal use of another function. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-Figure 6 As shown, an air purifier with adjustable blowing angle includes: a fuselage 1, on which a first air inlet 110 and a first air outlet 120 are provided; the first air inlet 110 is located on both sides of the fuselage 1, and the air intake on both sides can provide air intake efficiency, improve air purification efficiency, and facilitate the heat dissipation of the first fan 21; the first air outlet 120 is located in the middle of the fuselage 1, and is arranged upwardly and tilted, so as to facilitate blowing the purified air to the second air inlet 301. The air purification component 2 is arranged in the fuselage 1, and includes a filter (not marked in the figure) and a first fan 21, and the first fan 21 can inhale air from the first air inlet 110, and pump it to the first air outlet 120 through the filter; the filter is arranged at a position close to the first air inlet 110, and the air entering from the first air inlet 110 first passes through the filter, and the filter filters the pollutants in the air to ensure the air quality, and will not pollute other components in the fuselage 1, thereby improving its service life. The blowing assembly 3 is arranged in the fuselage 1 and above the air purification assembly 2. The blowing assembly 3 includes a housing 30 and a second fan 31 arranged in the housing 30. The second fan 31 includes a motor 310 and a wind wheel 311 driven by the motor 310. The wind wheel 311 is sleeved on the output shaft of the motor 310. The housing 30 is provided with a second air inlet 301 and a second air outlet 302. The second fan 31 is located between the second air inlet 301 and the second air outlet 302. The second fan 31 can draw air from the second air inlet 301 to the second air outlet 302 for discharge. The housing 30 is rotatably arranged in the fuselage 1.

[0039] Among them, Figure 1 , Figure 2 and Figure 4As shown, the fuselage 1 includes a base 10 and a left panel 11, a rear panel 12, a right panel 13 and a front panel 14 arranged on the base 10 in sequence. The left panel 11 and the right panel 13 are both provided with the first air inlet 110, and the filter screen is provided at both of the first air inlet 110; the first air outlet 120 is located on the rear panel 12, and the housing 30 is hinged on the left panel 11 and the right panel 13. Among them, the left panel 11 includes a left panel inner panel and a left panel outer panel, and the right panel 13 includes a right panel inner panel and an inner panel outer panel. The left panel outer panel and the right panel outer panel respectively cover the specific structures on the left panel inner panel and the right panel inner panel to improve the aesthetics.

[0040] The first air outlet 120 is located at the rear side of the body 1, the second air inlet 301 is located at the rear side of the housing 30 and above the first air outlet 120, and the second air outlet 302 is located at the front side of the housing 30; the air purified by the air purification component 2 can be discharged from the first air outlet 120, and the second fan 31 can inhale the purified air discharged from the first air outlet 120 from the second air inlet 301 and discharge it from the second air outlet 302. It should be explained that in normal use, the front side is the side facing the first air outlet 120, which is generally directly facing people.

[0041] The specific hinged hinge method of the blowing assembly 3 is as follows: a hinge hole 111 is provided on each of the left side plate 11 and the right side plate 13. Specifically, the hinge hole 111 is respectively opened on the inner plate of the left side plate and the inner plate of the right side plate. A hinge part 303 is protruded on both the left and right sides of the shell 30. The hinge part 303 on the left side of the shell 30 is rotatably arranged in the hinge hole 111 of the left side plate 11, and the hinge part 303 on the right side of the shell 30 is rotatably arranged in the hinge hole 111 of the right side plate 13. An inclined part 121 is provided on the rear plate 12, which is gradually inclined outward from top to bottom. The first air outlet 120 is arranged on the inclined part 121, so that the air g purified by the air purification assembly 2 can be sucked into the blowing assembly 3. After being blown to the human body, the good air quality improves the human comfort.

[0042] During use, the overall module of the blowing component 3 can be rotatably set on the fuselage 1 and is located above the air purification component 2, so that the air inlet angle and the air outlet angle of the blowing component 3 can be adjusted simultaneously, which is equivalent to adjusting the upper and lower relative positions of the second air inlet 301 relative to the first air outlet 120, thereby adjusting the blowing angle while adjusting the amount of air g purified by the air purification component 2 inhaled by the blowing component 3. Because the first air outlet 120 is positioned below the second air inlet 301 and the first air outlet 120 is tilted upward, the air g purified by the air purification component 2 is discharged from the first air outlet 120, sucked in from the second air inlet 301 and discharged to the second air outlet 302, and then discharged to the person. When the second air inlet 301 end of the blowing component 3 is closer to the first air outlet 120, it sucks in more purified air g. When a large amount of purified air g is to be discharged, the inclination angle of the blowing component 3 to the first air outlet 120 can be increased to make the second air inlet 301 closer to the first air outlet 120; when the second air inlet 301 end of the blowing component 3 is farther from the first air outlet 120, it sucks in less purified air g; the diversification of blowing modes is achieved, which can be suitable for different application scenarios.

[0043] like Figure 3 and Figure 4 As shown, the left side plate 11 is provided with an arc-shaped slide groove 112 on both sides of its hinge hole 111, and the right side plate 13 is also provided with an arc-shaped slide groove 112 on both sides of its hinge hole 111; two bosses 304 are protruded on the left and right sides of the housing 30, wherein the two bosses 304 on the left side of the housing 30 are respectively slidably disposed in the two arc-shaped slide grooves 112 of the left side plate 11, and the two bosses 304 on the right side of the housing 30 are respectively slidably disposed in the two arc-shaped slide grooves 112 of the right side plate 13. The center of the two arc-shaped slide grooves 112 on the left side plate 11 coincides with the center of the hinge hole 111 on the left side plate 11; the center of the two arc-shaped slide grooves 112 on the right side plate 13 coincides with the center of the hinge hole 111 on the right side plate 13, so as to ensure that the slide groove 112 will not interfere with the bosses 304 when the blowing assembly 3 rotates. The setting of the arc-shaped slide groove 112 ensures that no interference occurs when the hinge part 303 rotates, that is, when the entire blowing assembly 3 is rotated, and can control the upper and lower limit positions of the rotation of the blowing assembly 3, that is, control the upward and downward angles of the blowing assembly 3.

[0044] Specifically, the hinged part 303 includes a plurality of cylinders 303A and a plurality of threaded columns 303B with threaded holes arranged along the inner wall of the hinged hole 111, and the cylinders 303A and / or the threaded columns 303B are movably pressed against the inner wall of the hinged hole 111. The arrangement of the cylinders 303A and the threaded columns 303B ensures that the hinged part 303 and the fuselage 1 are in line contact rather than full surface contact, ensuring that the rotation of the blowing component is smooth, with low friction and small resistance. The blowing component 3 also includes a limit cover 32, which is provided with a plurality of through holes 320, and screws pass through the through holes 320 and are connected to the threaded holes to fix the limit cover 32 on the threaded columns 303B. The arrangement of the limit cover 32 can prevent the blowing component 3 from detaching from the fuselage 1, thereby improving the structural stability.

[0045] Optionally, a PTC heater 22 is also provided in the shell 30, and the second fan 31 can draw air at the second air inlet 301 to the PTC heater 33 for heating, and then discharge it from the second air outlet 302, so as to control the PTC heater 33 to work or not, and further control whether the blowing component 3 outputs cold air or warm air.

[0046] In actual use, a PTC heater 33 can be installed in the housing 30 of the blowing assembly 3 to act as a heater. Compared with a general heating element, the PTC heater 33 does not emit yellow light, making it more comfortable to use. In addition, since the air purification assembly 2 and the blowing assembly 3 in this structure are independent modules, the air purification function and the cold wind and warm wind fan functions can work together, and the air purification function and the cold wind and warm wind fan functions can work independently. When a single function is damaged, it does not affect the normal use of another function.

[0047] In this solution, the blowing component 3 of the air purifier is adjustable as a whole, and the height of the air inlet and the air outlet of the blowing component 3 can be adjusted at the same time. It is easy to adjust and can be used as an air purifier or a fan alone or both. They can work together or work alone.

[0048] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
