Description

Technical Field

[0001] The utility model relates to the field of air purifiers, in particular to an air duct structure of an air purifier. Background Art

[0002] As people pay more attention to personal health and public environmental health, air purifiers are used in home environments and public environments such as medical and industrial environments. Their main function is to remove particulate matter in the air (including various allergens, PM2.5, PM10, toxic gases, etc.). However, the air duct structure of air purifiers currently on the market generally has the following shortcomings:

[0003] (I) The fan assembly in the air duct is generally not equipped with a shock-absorbing structure, which is easy to generate vibration during the use of the air purifier, affecting the user experience and the service life of the air purifier. For this reason, air purifiers with fan assemblies equipped with shock-absorbing structures have gradually appeared on the market, but most of these shock-absorbing structures are relatively complex, and their shock-absorbing effects are not ideal. The manufacturing and assembly costs of air purifier products are also high, making it difficult to effectively improve the market competitiveness of the products.

[0004] (ii) The fan assembly is generally installed on the side facing the front shell of the air purifier, that is, the installation structure of the fan assembly is located in the air inlet of the air duct, occupying part of the area of ​​the air inlet, affecting the air intake efficiency of the air duct and also reducing the purification efficiency of the air purifier.

[0005] (3) At the entrance of the air duct, the air inlet net of the air purifier is usually fixed on the shell, which has a complex structure and is not easy to disassemble, making it inconvenient for users to clean and maintain. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an air duct structure for an air purifier, which can effectively reduce the vibration generated by the air purifier during use, and has a simple structure, which is convenient for assembling a fan assembly, and the fan assembly has a large air inlet area and high air inlet efficiency.

[0007] The technical solution of the utility model is: an air duct structure of an air purifier, including an air duct member, a fan assembly, a motor bracket and a shock-absorbing locking assembly, the air duct member is connected to the rear shell of the air purifier to form an air duct, the fan assembly is arranged in the air duct, the fan assembly is arranged on the motor bracket, and the motor bracket is installed on the rear shell of the air purifier through the shock-absorbing locking assembly; the side of the air duct member opposite to the motor bracket is the air inlet of the air duct. Among them, the rear side of the air duct member is connected to the rear shell of the air purifier, and the two cooperate to form an air duct, the air outlet assembly of the air purifier (including the air outlet net, the air guide cover and other components) is arranged at the top of the air duct, the front side of the air duct member is connected to the air inlet net described below to form the front shell of the air purifier, and the air inlet of the air duct is connected to one side of the air inlet net. In the above structure, on the one hand, by installing the motor bracket on the rear shell, it is avoided that the installation structure of the fan assembly (mainly the motor and motor bracket in the fan assembly) is arranged in the air inlet of the air duct to occupy the area of ​​the air inlet of the air duct; on the other hand, by arranging a shock-absorbing locking assembly between the motor bracket and the rear shell of the air purifier, it is possible to effectively prevent the motor from vibrating and affecting the entire air purifier during the use of the air purifier, thereby reducing the vibration of the air purifier and improving the user experience.

[0008] The shock-absorbing locking assembly includes a shock-absorbing rubber pad and a screw with a pad. The rear shell of the air purifier is provided with a raised mounting hole, the motor bracket is provided with a through hole for mounting, the shock-absorbing rubber pad is arranged in the through hole on the motor bracket, and the shock-absorbing rubber pad is sleeved on the outer periphery of the mounting hole, the screw with a pad is locked in the mounting hole, and the gasket and nut on the screw with a pad are pressed against the shock-absorbing rubber pad. That is, the through hole on the motor bracket, the shock-absorbing rubber pad and the mounting hole on the rear shell are coaxially arranged from outside to inside. By arranging the shock-absorbing rubber pad between the motor bracket and the rear shell, the rigid contact between the motor bracket and the rear shell is avoided, so that during the use of the air purifier, the vibration generated by the fan assembly can be prevented from causing the vibration of the entire air purifier, reducing the vibration of the air purifier, thereby improving the user experience.

[0009] The through holes on the motor bracket are distributed along the edge of the motor bracket, and the edge of the through holes has a notch, wherein the notch can facilitate the rapid embedding of the shock-absorbing rubber pad into the through hole of the motor bracket.

[0010] The outer periphery of the shock-absorbing rubber pad is provided with a groove, and the through hole on the motor bracket is embedded in the groove. The overall thickness of the shock-absorbing rubber pad is greater than the thickness of the motor bracket, and the width of the groove is approximately equal to the thickness of the motor bracket at the through hole, so as to ensure that the motor bracket can be stably installed on the rear shell of the air purifier.

[0011] The inner side of the shock-absorbing rubber pad has intermittently distributed convex strips. The arrangement of the convex strips can reduce the installation resistance between the shock-absorbing rubber pad and the installation hole, so as to achieve the purpose of rapid assembly, and after the motor bracket is installed, each convex strip is pressed against the outer periphery of the installation hole on the rear shell, so as to form a stable connection structure.

[0012] The fan assembly comprises a motor and a wind wheel. The motor is arranged in the middle of the wind wheel. One side of the motor is mounted on the motor bracket. The other side of the wind wheel opposite to the motor bracket is connected to the air inlet of the air duct.

[0013] The outside of the air inlet of the air duct is provided with a filter assembly and an air inlet net in sequence, and the air inlet net is the integral air inlet of the air purifier. The air inlet net forms the front shell of the air purifier, that is, the integral air inlet is located on the front shell, so the air inlet of the air duct avoids the installation structure of the fan assembly (that is, including the motor bracket, the shock-absorbing locking assembly and other components), so the air inlet area of ​​the air duct inlet can be expanded, and the purification efficiency of the air purifier can be improved.

[0014] The air inlet net is detachably mounted on the air duct member, a hook is provided at the lower part of the air inlet net, a buckle is provided at the upper part of the air inlet net, and correspondingly, a hook groove is provided at the lower part of the air duct member on the side facing the air inlet net, and a buckle hole is provided at the upper part of the air duct member on the side facing the air inlet net; when the air inlet net is installed, the hook is buckled in the hook groove, and the buckle is embedded in the buckle hole. Through the cooperation of the hook and the hook groove, the buckle and the buckle hole, the air inlet net can be quickly installed and removed from the air purifier, which is convenient for the replacement or cleaning of the filter assembly, and also convenient for the maintenance and assembly of the air purifier.

[0015] Furthermore, an air inlet net rubber pad is also provided at the buckle hole. When the air inlet net is installed, the air inlet net rubber pad is embedded in the buckle hole, and the buckle on the air inlet net is embedded in the air inlet net rubber pad. By providing the air inlet net rubber pad, the vibration generated during the use of the air purifier can be further reduced, thereby improving the user experience.

[0016] When the air duct structure of the above-mentioned air purifier is applied, its working principle is as follows: in the air purifier, the wind wheel works under the drive of the motor, and under the drive of the wind wheel, the indoor air is sucked in from the air inlet net, and after being purified by the filter components inside the air purifier, it enters the air duct from the air inlet of the air duct, and the air flow rises in the air duct and is finally sent out from the air outlet component at the top of the air duct; wherein, since the air inlet net connected to the air duct inlet is the front shell of the air purifier, the motor and the motor bracket are installed on the rear shell of the air purifier, and there is no obstruction to the air duct inlet, thereby increasing the air inlet area, improving the air intake volume and the efficiency of the air purifier as a whole; and during the use of the air purifier, a shock-absorbing locking component is provided at the connection between the motor bracket and the rear shell to prevent the motor from vibrating and affecting the air purifier as a whole, thereby reducing the vibration of the air purifier as a whole, thereby improving the user experience.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the air duct structure of the air purifier, the motor and the motor bracket are mounted on the rear shell of the air purifier to avoid blocking the air inlet of the air duct by the motor and the motor bracket, thereby increasing the air inlet area of ​​the air duct, improving the air inlet volume of the air duct and the efficiency of the entire air purifier; at the same time, a shock-absorbing locking assembly is provided at the connection between the motor bracket and the rear shell, so that during the use of the air purifier, the vibration of the motor can be effectively prevented from affecting the entire air purifier, thereby reducing the vibration of the air purifier and improving the user experience.

[0019] In the air duct structure of the air purifier, the air inlet net on the outer side of the air inlet of the air duct is also arranged in a detachable assembly mode. The air inlet net is connected to the air duct component by snap-fitting connection or snap-fitting connection with the air inlet net rubber pad. The air inlet net can be quickly installed and removed from the air purifier, which is convenient for replacement or cleaning of the filter component and also convenient for maintenance and assembly of the air purifier.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0033] Example 1

[0034] This embodiment provides an air duct structure of an air purifier, such as Figure 1 or Figure 2 As shown, it includes a duct member 1, a fan assembly 2, a motor bracket 3 and a shock-absorbing locking assembly 4. The duct member is connected to the rear shell 5 of the air purifier to form an air duct. The fan assembly is arranged in the air duct, and the fan assembly is arranged on the motor bracket. The motor bracket is installed on the rear shell of the air purifier through the shock-absorbing locking assembly. The side of the duct member opposite to the motor bracket is the air inlet 1-3 of the duct. Among them, the rear side of the duct member is connected to the rear shell of the air purifier, and the two cooperate to form an air duct. The air outlet assembly of the air purifier (including the air outlet net 8, the air guide cover 9 and other components) is arranged at the top of the air duct. The front side of the duct member is connected to the air inlet net described below to form the front shell of the air purifier. The air inlet of the duct is connected to one side of the air inlet net. In the above structure, on the one hand, by installing the motor bracket on the rear shell, it is avoided that the installation structure of the fan assembly (mainly the motor and motor bracket in the fan assembly) is arranged in the air inlet of the air duct to occupy the area of ​​the air inlet of the air duct; on the other hand, by arranging a shock-absorbing locking assembly between the motor bracket and the rear shell of the air purifier, it is possible to effectively prevent the motor from vibrating and affecting the entire air purifier during the use of the air purifier, thereby reducing the vibration of the air purifier and improving the user experience.

[0035] like Figure 2As shown, the shock-absorbing locking assembly includes a shock-absorbing rubber pad 4-1 and a screw with a pad 4-2. A raised mounting hole 5-1 is provided on the rear shell of the air purifier. A through hole 3-1 for mounting is provided on the motor bracket. The shock-absorbing rubber pad is arranged in the through hole on the motor bracket, and the shock-absorbing rubber pad is sleeved on the outer periphery of the mounting hole.

That is, the through hole on the motor bracket, the shock-absorbing rubber pad and the mounting hole on the rear shell are coaxially arranged from outside to inside. By arranging the shock-absorbing rubber pad between the motor bracket and the rear shell, rigid contact between the motor bracket and the rear shell is avoided. During the use of the air purifier, the vibration generated by the fan assembly can be prevented from causing vibration of the entire air purifier, reducing the vibration of the air purifier, thereby improving the user experience. Among them, on the motor bracket, such as Figure 2 As shown, the through holes are distributed along the edge of the motor bracket, and the edge of the through holes is provided with notches.

The motor is arranged in the middle of the wind wheel, one side of the motor is mounted on the motor bracket, and the other side of the wind wheel opposite to the motor bracket is connected to the air inlet of the air duct.

[0038] like Figure 2 As shown, the outside of the air inlet of the air duct is provided with a filter assembly 6 and an air inlet net 7 in sequence, and the air inlet net is the overall air inlet of the air purifier. The air inlet net forms the front shell of the air purifier, that is, the overall air inlet is located on the front shell, so the air inlet of the air duct avoids the installation structure of the fan assembly (that is, including the motor bracket, the shock-absorbing locking assembly and other components), so the air inlet area of ​​the air duct inlet can be expanded, and the purification efficiency of the air purifier can be improved.

[0039] When the air duct structure of the above-mentioned air purifier is applied, its working principle is as follows: in the air purifier, the wind wheel works under the drive of the motor, and under the drive of the wind wheel, the indoor air is sucked in from the air inlet net, and after being purified by the filter components inside the air purifier, it enters the air duct from the air inlet of the air duct, and the air flow rises in the air duct and is finally sent out from the air outlet component at the top of the air duct; wherein, since the air inlet net connected to the air duct inlet is the front shell of the air purifier, the motor and the motor bracket are installed on the rear shell of the air purifier, and there is no obstruction to the air duct inlet, thereby increasing the air inlet area, improving the air intake volume and the efficiency of the air purifier as a whole; and during the use of the air purifier, a shock-absorbing locking component is provided at the connection between the motor bracket and the rear shell to prevent the motor from vibrating and affecting the air purifier as a whole, thereby reducing the vibration of the air purifier as a whole, thereby improving the user experience.
