Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a shock absorbing structure and an air purifier. Background Art

[0002] With the popularity of air purifiers, users' requirements for air purifiers are gradually increasing. Traditional air purifiers are mainly used for air purification, and are mainly used to adsorb various allergens, PM2.5, PM10, toxic gases or bacteria. The main driving force of existing air purifiers is generated by motors, and the operation of motors will generate vibrations and noise. When the vibration is transmitted to other structures in the air purifier, adjacent structures will collide due to vibration, increasing the noise. Although existing air purifiers are also equipped with shock-absorbing structures, the shock-absorbing effect is poor due to unreasonable structural design, and the structure is relatively complex, the production cost is high, and the noise during the operation of the air purifier is not significantly reduced.

[0032] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0033] Please refer to Figure 1-Figure 5 An air purifier comprises an air outlet component 1, an air inlet component 2, a shock absorbing structure 3 and a shell 4; the air outlet component 1, the air inlet component 2 and the shock absorbing structure 3 are all arranged in the shell 4, the shock absorbing structure 3 is clamped between the air outlet component 1 and the air inlet component 2 and is clamped with the air outlet component 1; the air inlet component 2, the shock absorbing structure 3 and the air outlet component 1 are connected in sequence along the air outlet direction; the shock absorbing structure 3 comprises an air guide bracket 31 and a shock absorbing component 32; in the axial direction of the air guide bracket 31, the air guide bracket 31 has a mounting surface 311, the mounting surface 311 is provided with a shock absorbing groove 312, one end of the shock absorbing component 32 is embedded in the shock absorbing groove 312 and clamped between the air guide bracket 31 and the motor 22, and the other end of the shock absorbing component 32 protrudes outside the mounting surface 311.

[0034] It can be understood that by sandwiching the shock absorbing assembly 32 between the motor 22 and the air guide bracket 31, a shock absorbing effect is played, direct contact between the motor 22 and the air guide bracket 31 is avoided, the vibration frequency propagated along the axial direction of the air guide bracket 31 is reduced, the shock absorbing effect is improved, and the noise during the operation of the air purifier is reduced.

[0035] In some embodiments, the shock absorbing assembly 32 includes a shock absorbing pad 321 and a fastener 322; one end of the shock absorbing pad 321 is embedded in the shock absorbing groove 312, and the fastener 322 passes through the shock absorbing pad 321 and is detachably connected to the motor 22. The fastener 322 can improve the connection tightness between the shock absorbing pad 321 and the motor 22 and the air guide bracket 31. In addition, the fastener 322 is set through the shock absorbing pad 321 and has no direct contact with the air guide bracket 31. Therefore, even if the vibration of the motor 22 is transmitted through the fastener 322, it will not directly act on the air guide bracket 31. This structural design can not only connect the air guide bracket 31 to the motor 22 without contact, but also have a good shock absorbing effect. Among them, the fastener 322 is a screw.

[0036] In some embodiments, the shock absorbing groove 312 has mutually connected mounting notches 313 and a groove body 314 matching the shock absorbing assembly 32; in the radial direction of the air guide bracket 31, the mounting notches 313 and the groove body 314 are sequentially arranged in a direction gradually approaching the axis of the air guide bracket 31. Preferably, the axial section of the shock absorbing pad 321 is I-shaped, and the groove body 314 matches the concave part of the shock absorbing pad 321, so that one end of the shock absorbing pad 321 protrudes outside the mounting surface 311, thereby fixing the shock absorbing pad 321.

[0037] In some embodiments, the width of the installation notch 313 gradually decreases in the direction gradually approaching the slot body 314, and the width of the connection between the installation notch 313 and the slot body 314 is less than the maximum width of the slot body 314. Preferably, the slot body 314 is an incomplete circle, and the maximum width of the slot body 314 refers to the maximum diameter of the slot body 314. Correspondingly, the width of the connection between the installation notch 313 and the slot body 314 will also be less than the outer diameter of the recessed part of the shock-absorbing pad 321. Since the axial section of the shock-absorbing pad 321 is I-shaped, in order to ensure that the shock-absorbing pad 321 can be installed in the slot body 314 and to ensure that one end of the shock-absorbing pad 321 can be clamped between the motor 22 and the air guide bracket 31, the installation notch 313 is provided to provide installation space for the shock-absorbing pad 321, and due to the width setting of the connection between the installation notch 313 and the slot body 314, the shock-absorbing pad 321 can be limited to prevent the shock-absorbing pad 321 from being separated from the air guide bracket 31.

[0038] In some embodiments, one end of the installation notch 313 away from the slot body 314 extends along the axial direction of the air guide bracket 31 to provide a space for the installation of the shock absorbing pad 321 .

[0039] In some embodiments, at least two shock absorbing assemblies 32 and shock absorbing grooves 312 are respectively provided, and all shock absorbing assemblies 32 and shock absorbing grooves 312 are arranged at equal intervals along the circumference of the wind guide bracket 31. Preferably, four shock absorbing assemblies 32 and shock absorbing grooves 312 are respectively provided to further reduce the transmission of vibration.

[0040] In some embodiments, the air inlet assembly 2 includes a coaxially arranged lower air duct 21 and a motor 22 ; the motor 22 is embedded in the lower air duct 21 and is detachably connected to the shock absorbing structure 3 .

[0041] In some embodiments, the air outlet assembly 1 includes an upper main body and an upper air duct 11, an air duct bracket 12 and an air outlet net 13 arranged in sequence along the air outlet direction, the air duct bracket 12 is pressed against the air guide bracket 31, the air outlet net 13 is connected to the upper air duct 11, and the air duct bracket 12 is embedded in the upper air duct 11.

[0042] In some embodiments, a clamping platform 315 is provided on the circumferential side wall of the air guide bracket 31, and a buckle 14 is provided on the air outlet assembly 1, and the air outlet assembly 1 is connected to the air guide bracket 31 through the buckle 14 and the clamping platform 315. Specifically, the buckle 14 is located on the outer wall of one end of the upper air duct 11 close to the air guide bracket 31, and multiple buckles 14 and clamping platforms 315 are provided, all of which are arranged at equal intervals, and the clamping platforms 315 are arranged one by one with the buckles 14.

[0043] The working principle of the utility model is:

[0044] Driven by the motor 22 , the airflow passes through the lower air duct 21 , the air guide bracket 31 , the upper air duct 11 and the air duct bracket 12 in sequence and is then discharged from the air outlet net 13 .
