Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Example 1

Fig. 1 to 3 show a first embodiment of a device having a fluid bag noise and shock reducing structure. It should be understood that the device with the liquid bag noise-reducing and shock-absorbing structure of the present invention can also be used in the case of other vibration bodies such as a pump body, but in the present embodiment, the device is described as being used in a vacuum cleaner having the motor 2. The motor 2 is a core part of a cleaner in which suction force is generated, and thus is a major source of vibration and noise. As shown in fig. 1, one end of the motor 2 is an air inlet end 21, and the other end is an air outlet end 22. The motor 2 is typically mounted within a housing 3. As can be seen from fig. 1 and 2, the outer periphery of the motor 2 is cylindrical, the housing 3 covers the outer periphery of the motor 2, and a circular cylindrical space is formed between the circumferential outer surface of the motor 2 and the inner surface of the housing 3.

The device with the liquid bag noise-reducing and shock-absorbing structure in the embodiment comprises the motor 2, the machine shell 3 and the liquid bag 1 filled with liquid 11. The liquid 11 fills the chamber formed by the body of the sac 1. The liquid capsule 1 is arranged in the above-mentioned circular cylindrical space between the motor 2 and the housing 3, and the space is filled with the liquid capsule 1 as a whole. That is, as shown in fig. 3, the sac 1 at least completely covers the entire circumferential outer surface of the motor 2, and as shown in fig. 1, the inner surface of the assembled sac 1 is closely attached to the circumferential outer surface of the motor 2, and the outer surface of the sac 1 is closely attached to the inner surface of the casing 3. Since the liquid bag 1 is filled with the liquid 11, the liquid 11 forms a certain liquid pressure, and under the action of the liquid pressure, the liquid bag 1 can simultaneously extrude the outer surface of the motor 2 and the inner surface of the casing 3.

The utility model discloses a device with shock-absorbing structure that makes an uproar falls in liquid bag utilizes the liquid 11 in the liquid bag 1 to absorb in a large number and the noise that filters motor 2 and produce, has reduced the whole sound that sends of dust catcher by a wide margin, has improved the tone quality volume of dust catcher. Further, by means of the liquid bag 1, flexible assembly is achieved between the motor 2 and the machine shell 3, so that the problem that overall vibration is caused by vibration of the motor 2 is solved, and the source of noise generation is reduced fundamentally. In addition, in the case of a vacuum cleaner, the motor 2 is generally operated at a high speed, and thus a large amount of heat is easily generated in a short time. Because the liquid 11 in the liquid bag 1 has better heat conduction performance than air, and simultaneously because the liquid bag 1 is closely contacted with the motor 2 and the shell 3, the heat resistance around the motor 2 is small, and the heat emitted by the heat can be quickly conducted to the outside, thereby effectively cooling the motor 2 and improving the working performance of the motor 2.

It will be appreciated that the sac 1 is not filled with liquid 11 prior to assembly and is therefore in a flattened condition. When filled with liquid 11, the sac 1 is held up to form a circular cylinder which matches the above-mentioned space between the motor 2 and the casing 3, so that the sac 1 presses both the motor 2 and the casing 3.

Further, in order to enable the liquid bag 1 to form a compression between the motor 2 and the housing 3, facilitating a flexible connection therebetween, the bag body of the liquid bag 1 is preferably made of a soft, high-strength elastic material, such as rubber. Thus, the resonance phenomenon can be avoided, and the service life of the motor 2 is prolonged.

Further, the liquid 11 in the sac 1 may be used as long as it is chemically stable and has good heat-conducting properties. However, in the present embodiment, the liquid 11 is preferably water or oil in view of the heat radiation performance, the sound insulation effect, the availability, and the cost in combination.

With further reference to fig. 1 and 3, to facilitate filling of the liquid 11, the liquid capsule 1 is provided with a liquid filling port 12 at the same end as the discharge end 22 of the motor 2, the liquid filling port 12 projecting outwardly from the end of the liquid capsule 1 to facilitate connection to an external liquid filling device. The pouring opening 12 can be sealed by a sealing means, for example, preferably a valve 13. The liquid bag 1 only needs to be filled once, and the internal pressure of the liquid bag cannot be reduced along with time, so that a device for supplementing liquid does not need to be externally connected.

The fluid bag 1, filled with the fluid 11, can form a compression between the motor 2 and the housing 31, which compression simultaneously clamps the motor 2. In order to form good filling and extrusion among the liquid bag 1, the motor 2 and the machine shell 3, the range of the liquid pressure inside the liquid bag 1 is preferably 20-60 kpa, when the liquid pressure reaches the numerical range, the elasticity and the damping state of the liquid bag 1 reach the best, so that the shock absorption effect on the motor 2 is better, meanwhile, the motor assembly can be sealed without additionally increasing a sealing ring, the number of parts required by the dust collector is reduced, and the cost is reduced.

The following will describe in detail the installation process of the device having the liquid bag noise and vibration reducing structure in the present embodiment. For ease of transport and installation, the sac 1 is in a flattened state prior to installation, without liquid being injected. In the assembling process, the capsule body of the liquid capsule 1 is assembled between the motor 2 and the shell 3. After the assembly is finished, the auxiliary liquid injection device is utilized to inject liquid into the cavity in the capsule body 1 through the liquid injection port 12 protruding from one end of the capsule body 1. When the injected liquid 11 reaches a certain pressure, such as the preferred pressure range described above, the liquid injection port 12 is closed by the valve 13. The liquid injection is completed at one time without additional liquid supplement.

Compared with the traditional rubber sealing ring, the installation mode is very convenient, the flexible assembly of the motor 2 is realized, the motor 2 and the damping sealing ring are prevented from being forcibly clamped into the shell 3, the assembly process and the difficulty are simplified, and the labor cost of assembly is saved. Use supplementary notes liquid equipment to annotate liquid bag 1, then will annotate liquid mouth 12 and seal to realize the lasting pressurize of liquid bag 1, guarantee that motor 2 lasts good syllable-dividing, shock attenuation, sealed and fixed.

Fig. 4 shows a second embodiment of the present invention, wherein the same parts as those of the first embodiment are not described again. Differences of the present embodiment from the first embodiment will be described in detail below.

In the present embodiment, the liquid bladder 1 covers the entire circumferential direction of the motor 2, and also covers a part of each of both end portions of the motor 2. As shown in fig. 4, the liquid bag 1 includes two portions, that is, a circular cylindrical portion 14 covering the circumferential outer surface of the motor 2 and extension portions 15 provided at both ends of the circular cylindrical portion 14, the extension portions 15 covering at least a part of the end surface of the motor 2. The annular cylindrical portion 14 communicates with the extension portion 15. Preferably, the extension 15 is annular and is formed by the end of the annular cylindrical portion 14 extending radially inwards, that is to say the axial section of the capsule 1 forms a "[ ]" shape.

Compared with the first embodiment, the liquid bag 1 in the embodiment further covers two end parts of the motor 2, so that the sealing effect on the motor 2 is better, the suction force at the position of the working suction head of the motor 2 is prevented from being reduced, the long-term cleaning effect of the dust collector is ensured, and the beneficial purpose of energy conservation is achieved. In addition, the liquid bag 1 increases the amount of the liquid 11 absorbing noise due to the extension of both ends, thereby further improving the noise reduction effect.

It should be understood that the above embodiments are only examples for clearly illustrating the present invention, and are not intended to limit the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
