Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to a vibration isolation and shock absorption component, a motor and a range hood. Background Art

[0002] The vibration and noise of the range hood during operation have always been a technical problem that technicians have been committed to overcoming. The vibration mainly comes from the motor that drives the range hood, and the vibration generated by its impeller is the culprit of the vibration and noise of the range hood.

[0003] To this end, there are technologies in the prior art that are specifically dedicated to reducing the vibration generated by the motor, such as using a shock-absorbing pad made of a shock-absorbing material, and setting the shock-absorbing pad at the connection between the motor and the range hood to weaken the transmission of the motor vibration and reduce noise.

[0004] However, this is not enough to significantly reduce vibration and noise. The structure of the shock-absorbing pad is usually relatively simple, and the vibration and noise reduction effect is limited. In actual use, there may also be a risk of material breakage and detachment. Utility Model Content

[0005] In view of the above technical problems, the present application further improves the structure of the prior art to obtain better vibration reduction and noise reduction effects. One of the purposes of the present utility model is to provide a vibration isolation and shock absorbing component, the second purpose is to provide a corresponding motor, and the third purpose is to provide a corresponding range hood.

[0006] The specific technical solutions are described below:

[0007] Vibration isolation and shock absorbing parts, including:

[0008] The spacer portion includes a first spacer disposed at one end of the vibration isolation and shock absorption member and a second spacer disposed at the other end of the vibration isolation and shock absorption member;

[0009] The airbag portion at least includes an airbag and is disposed between the first spacer and the second spacer;

[0010] The elastic part at least comprises an elastic member, one end of the elastic member acts on the spacer part, and the other end of the elastic member acts on the airbag part;

[0011] Alternatively, one end of the elastic member acts on the first spacer, and the other end of the elastic member acts on the second spacer.

[0012] In the above technical solution, the airbag uses air as the shock-absorbing medium. When the air is compressed, the friction generated inside the airbag is very small. Therefore, when the motor rotates, a better vibration isolation effect can be obtained to prevent the range hood from resonating and achieve a noise reduction effect. The first spacer and the second spacer use their own damping elasticity to cooperate with the airbag to achieve a double shock-absorbing effect. The elastic part also shares the compression force exerted on the airbag and the spacer to obtain a more significant vibration isolation and noise reduction effect, and to increase the service life of the vibration isolation and shock-absorbing parts.

[0013] Preferably, the first spacer has a first clamping platform protruding into the interior of the vibration isolation and shock absorption component, the second spacer has a second clamping platform protruding into the interior of the vibration isolation and shock absorption component, one end of the airbag part is sleeved on the first clamping platform, and the other end is sleeved on the second clamping platform.

[0014] Preferably, the airbag portion includes an annular load-bearing airbag and a cavity airbag, and a snap-on ring groove is formed on the outer surface of the connection between the load-bearing airbag and the cavity airbag;

[0015] The snap-in ring groove in the above technical solution is used to snap-in with the snap-in position of the motor.

[0016] Preferably, the cavity airbag is arranged above the bearing airbag, the bearing airbag is provided with a bearing platform at the connection with the cavity airbag, and an annular anti-slip ring is provided on the bearing platform;

[0017] The anti-slip ring in the above technical solution is located at the connection between the bearing airbag and the cavity airbag, which is also the connection part with the motor. Therefore, the anti-slip ring itself can increase the stability of the connection structure.

[0018] Further preferably, the elastic part at least includes an anti-slip elastic member, the anti-slip elastic member is accommodated in the cavity formed by the cavity airbag, one end of the anti-slip elastic member acts on the anti-slip ring member, and the other end acts on the first spacer;

[0019] The anti-slip elastic member in the above technical solution presses the anti-slip ring member to prevent it from slipping out.

[0020] Preferably, the elastic part further comprises a shock-absorbing elastic member, one end of the shock-absorbing elastic member acts on the first spacer, and the other end of the shock-absorbing elastic member acts on the second spacer.

[0021] Preferably, the anti-slip ring is a rigid part and has an interference fit with the inner wall of the airbag part;

[0022] In the above technical solution, the rigid anti-slip ring expands the airbags at its periphery outward to obtain a more stable connection structure between the vibration isolation and shock absorption component and the motor.

[0023] Preferably, it also includes a mounting hole that simultaneously penetrates the spacer portion, the airbag portion and the elastic portion;

[0024] The mounting hole in the above technical solution is used for mounting at the connection with the range hood.

[0025] A motor is connected to the vibration isolation and shock absorbing component in any of the above technical solutions.

[0026] The range hood is powered by a motor, and the motor is connected to the range hood via the vibration isolation and shock absorbing member in any of the above technical solutions.

[0027] In summary, the technical solution of the utility model has the following main beneficial effects:

[0028] Compared with the prior art, the technical solution of the utility model can achieve more significant vibration isolation and noise reduction effects and increase the service life of the vibration isolation and shock absorbing parts.

[0029] At the same time, it can also prevent the vibration isolation and shock absorption component from lateral disengagement, reduce the circumferential vibration amplitude of the motor, and improve the structural stability. Further or more detailed beneficial effects will be described in conjunction with specific embodiments in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The present invention is further explained with reference to the following embodiments:

[0045] The core technical problem faced by the technical solution of the embodiment of the present application comes from the inventor's accurate understanding of the prior art. Therefore, how to obtain more significant vibration isolation and noise reduction effects is a technical problem that the inventor urgently needs to solve.

[0046] At the same time, how to prevent the vibration isolation and shock absorbing component from lateral disengagement is also a technical problem that the inventors are trying to solve simultaneously.

[0047] It should be noted that the embodiments do not constitute a limitation on the protection scope of the claims of the utility model. According to the technical concepts provided / proven by the embodiments, all technical solutions that can be reasonably anticipated by technical personnel in the relevant technical field should be included in the protection scope of the claims of the utility model.

[0048] The embodiments are described in detail as follows:

[0049] Example :

[0050] Please refer to the instruction manual Figures 1 to 7 The vibration isolation and shock absorbing component 6 is composed of a vibration isolation part 1, an airbag part 2 and an elastic part 3.

[0051] Among them, the vibration isolation part 1 includes a first spacer 1.1 arranged at the upper end and a second spacer 1.2 at the lower end. The two spacers are both made of rubber. The first spacer 1.1 is provided with a first clamping platform 1.11 protruding downward, and the second spacer 1.2 is provided with a second clamping platform 1.21 upward. Correspondingly, the upper and lower ends of the airbag part 2 are provided with groove-shaped socket structures, which are socketed on the above-mentioned first clamping platform 1.11 and the second clamping platform 1.21 to achieve assembly and positioning between the airbag part 2 and the vibration isolation part 1.

[0052] The airbag portion 2 in this embodiment is composed of an integrally formed load-bearing airbag 2.1 and a cavity airbag 2.2. Both airbags are annular airbags, the center of the annular airbag is convenient for forming the above-mentioned sleeve structure, and a snap-in ring groove 2.3 is formed on the outer periphery of the connection between the load-bearing airbag 2.1 and the cavity airbag 2.2 for snapping with the motor.

[0053] In a preferred embodiment, a circular anti-slip ring 4 is arranged inside the airbag portion 2 of the vibration isolation and shock absorption component 6 and above the supporting airbag 2.1. The anti-slip ring 4 provides support for the above-mentioned clamping ring groove 2.3 to prevent the vibration isolation and shock absorption component 6 from laterally slipping out of the mounting structure of the motor, and can reduce the circumferential vibration amplitude of the motor and improve the structural stability.

[0054] The elastic part 3 in this embodiment includes an anti-slip elastic member 3.1 made of a spring, the lower end of the anti-slip elastic member 3.1 abuts against the anti-slip ring member 4, and the upper end of the anti-slip elastic member 3.1 abuts against the lower surface of the first spacer 1.1. The anti-slip elastic member 3.1 presses the anti-slip ring member 4 to prevent the anti-slip ring member 4 from falling off, which can further improve the stability of the connecting structure. In addition, the anti-slip elastic member 3.1 itself also participates in the distribution of compression force, thereby helping to improve the vibration isolation and noise reduction effects.

[0055] The elastic part 3 in this embodiment also includes a shock-absorbing elastic member 3.2 made of a spring. The shock-absorbing elastic member 3.2 passes through the center of the bearing airbag 2.1 and the cavity airbag 2.2, with one end abutting against the lower surface of the first spacer 1.1 and the other point abutting against the upper surface of the second spacer 1.2.

[0056] The technical solution of this embodiment uses the load-bearing airbag 2.1 and the cavity airbag 2.2 as the main vibration-damping components. The airbag provides a shock-absorbing effect through the change of air pressure, that is, air is used as the compression / rebound medium, and there is almost no rigid friction inside. Therefore, the vibration of the motor is greatly reduced after being weakened by the airbag. At the same time, in addition to providing an assembly basis, the spacer part 1 also makes the elastic damping effect of the first spacer 1.1 and the second spacer 1.2 cooperate with the above-mentioned airbag part 2 to play a double shock-absorbing role; and the ability of air and rubber to transmit sound is relatively weak, so the noise reduction effect is also very good; the anti-slip elastic part 3.1 and the shock-absorbing elastic part 3.2 in the elastic part 3 share the compression force on the airbag and the spacer, and provide a certain support strength, further improving the service life of the vibration isolation and shock-absorbing part 6, and preventing the resonance problem of the motor and the range hood.

[0057] In this embodiment, the bearing capacity of the airbag can be adjusted by the pressure inside the airbag to adapt to the weight and operating state of the motor and the associated impeller.

[0058] As an alternative embodiment, the airbag may also include other forms, such as a porous rubber material containing pores / voids in the middle.

[0059] Please continue to refer to the instruction manual Figures 1 to 7 In a further preferred embodiment, it is easy to understand that the anti-slip ring 4 is made of a rigid material, such as metal, etc., to enhance its supporting strength;

[0060] Regarding the anti-slip ring 4, another preferred idea is that the anti-slip ring 4 is interference-fitted with the inner wall of the airbag portion 2 at its periphery to obtain better connection tightness and make the connection structure more stable.

[0061] In a preferred embodiment, the vibration isolation and shock absorbing member 6 further includes a mounting hole 5 that simultaneously passes through the spacer portion 1, the airbag portion 2 and the elastic portion 3. A screw may be provided at the mounting hole 5 for mounting with the connecting arm of the range hood.

[0062] Please refer to the instruction manual Figures 4 to 7 , a motor 7, the vibration isolation and damping member 6 is installed at the arc-shaped motor clamping position 7.1 on the outer periphery of the motor 7, that is, the vibration isolation and damping member 6 is clamped at the motor clamping position 7.1 through the clamping ring groove 2.3 mentioned in the above embodiment;

[0063] In a preferred embodiment, the anti-drop ring 4, the airbag portion 2 on its outer periphery, and the motor latch 7.1 together form an interference fit structure, thus forming a stable connection portion.

[0064] A range hood is connected to the vibration isolation and shock absorption component 6 on the motor 7 via a connecting arm, the connecting arm is provided with a connecting hole, and the connecting hole and the mounting hole 5 on the vibration isolation and shock absorption component 6 are connected via screws.
