DETAILED DESCRIPTION

Hereinafter the present invention will be described in detail with reference to the accompanying drawings and the specific embodiments.

First, a blower device10according to a first embodiment of the present invention will be described with reference toFIGS.1-4. As shown inFIG.1, the device10comprises a case2and a blower vibration source1mounted in the case2. The blower vibration source1is, for example, a motor of the blower device. Those skilled in the art will readily appreciate that the blower device10also includes some other conventional components, which are well known in the art and thus detailed description thereof will be omitted herein.

According to the present invention, a locating buffering member3is disposed at a top portion of the blower vibration source1, and is used to connect the blower vibration source1to an inner side of a top wall of the case2. In this embodiment, as more clearly shown inFIG.4, the locating buffering member3may include a locating ring3.1which is extended into a corresponding locating seat2.4disposed at the inner side of the top wall of the case2. The locating seat2.4is configured to have an inner diameter which is slightly larger than an outer diameter of the locating ring3.1, so that point contact or line contact can be formed between the locating ring3.1and the locating seat2.4. In addition, the locating ring3.1may be disposed at the top portion of the blower vibration source1via a well-known structure, such as a complementary engagement projection-groove structure. By providing the locating ring3.1, not only lateral movement of the blower vibration source1due to high-frequency vibration can be controlled, but also a portion of vibration can be effectively dispersed.

According to the present invention, the blower device10includes a connection buffering member4associated with the blower vibration source1. In the first embodiment of the present invention, the connection buffering member4is configured as a cylindrical component in which at least a part of the blower vibration source1is received. The blower device10also includes a support buffering member5for supporting the connection buffering member4in which at least a part of the blower vibration source1is received on a bottom wall of the case2.

FIG.3illustrates the support buffering member5clearly. As shown, in the first embodiment of the present invention, the blower device10includes three support buffering members5which are preferably arranged uniformly in a circumferential direction. It will be readily understood that more support buffering members5may be disposed as required. Each of the support buffering members5comprises a support pillar5.1extended outwards from a bottom end of the connection buffering member4and three support legs5.2which are spaced apart from each other and extended outwards from an end surface of the support pillar5.1. The three support legs5.2of each of the support buffering members5collectively form a horn-shaped part extended and expanded gradually from the end surface of the support pillar5.1. The three support legs5.2of each of the support buffering members5are received in a respective receiving groove2.5(referring toFIG.4) disposed on a bottom surface of the case2. Preferably, the receiving grooves2.5each is sized and shaped to just receive the three support legs5.2. By providing the support buffering members5each having three independent support legs5.2, vibration from the blower vibration source1can be effectively dispersed. In addition, in the case of the blower vibration source1producing a downward displacement, the receiving grooves2.5can limit each of the support legs5.2inside, thereby limiting downward movement and freedom of rotation of the blower vibration source1.

The above-mentioned locating buffering member3and the connection buffering member4are made of a material which can provide buffering function. For example, they may be made of a silicone material. For the support buffering member5, at least the support legs5.2are made of a material which can provide buffering function, e.g., a silicone material. The support pillars5.1may be made of a rigid material such as plastic, alternatively it may be made of a silicone material.

According to a specific embodiment of the present invention, as shown inFIG.4, the case2may include a lower case2.1, a middle case2.2and an upper case2.3. Here, the locating seat2.4is disposed at the upper case2.3, and the receiving grooves2.5are disposed at the lower case2.1. Compared with a case having an integral structure, the case having this three-part structure can disperse the high-frequency vibration from the blower vibration source1more effectively.

According to a preferred embodiment of the present invention, as shown inFIG.2, a blower seal ring6is connected with the blower vibration source1, and is tightly connected with the case2, specifically the middle case2.2. After the blower vibration source1is mounted into the case2, the blower seal ring6can function as limiting rotation of the blower vibration source1. In addition, a thin-walled butterfly-shaped vibration absorbing structure may be provided in the blower seal ring6, so that an amplitude of high-frequency vibration of the blower vibration source1can be effectively dispersed.

As shown inFIG.3, rigid stoppers4.1can be provided optionally on a bottom surface of the connection buffering member4. In the illustrated embodiment, each of three rigid stoppers4.1is arranged between two adjacent support buffering members5. The rigid stoppers4.1are configured to be extended further than the support pillars5.1of the support buffering member5. Thus, when the blower vibration source1produces excessive vibration, the rigid stoppers4.1will be brought into contact with a bottom surface of the lower case2.1, thereby limiting further downward movement of the blower vibration source1.

Hereinafter the blower devices according to the second to the seventh embodiments will be described with reference toFIGS.5-10. In order to avoid redundancy, only differences from the first embodiment shown inFIGS.1-4will be described and repeated description can be referred to the description above.

FIG.5illustrates a blower device20according to a second embodiment of the present invention. In the second embodiment, the blower device20does not include the support buffering member5shown in the first embodiment. However, a connection buffering member24of the blower device20includes a cylindrical part24.1in which at least a part of the blower vibration source1is received and a connection part24.2extended horizontally from a peripheral wall of the cylindrical part24.1The connection part24.2is supported on a support platform22.6disposed at an inner wall of a case22. For example, the connection part24.2can be supported on the support platform22.6via a structure with reduced contact surface (such as a tapered portion). The cylindrical part24.1and the connection part24.2each is made of a material which can provide buffering function, e.g., a silicone material. Thus, in the second embodiment, the blower vibration source1is actually hung in the case22via the connection buffering member24. In this case, vibration of the blower vibration source1can be dispersed effectively by a locating buffering member23and the connection buffering member24.

FIG.6illustrates a blower device30according to a third embodiment of the present invention. The blower device30is substantially the same as the blower device20according to the second embodiment shown inFIG.5. The difference lies in that, in the blower device30, a connection part34.2and an inner wall of a case32are engaged with each other via a hook structure. Specifically, a hook support part32.6is provided at the inner wall of the case32, and a free end of the connection part34.2is configured as a hook which can be hung on the hook support part32.6. In this way, the blower vibration source1can be hung within the case32reliably, which will benefit dispersion of vibration energy.

FIG.7illustrates a blower device40according to a fourth embodiment of the present invention. In this embodiment, the connection buffering member44is configured as a box body, and a blower vibration source41is completely received in the connection buffering member44. In addition, a locating buffering member43and a support buffering member45are integrated with a top surface and a bottom surface of the connection buffering member44respectively. The locating buffering member43and the support buffering member45may have the same structures as those in the first embodiment, alternatively they may be simple tapered buffering members, so that point contact or line contact is formed between the buffering members and the case. In addition, a connection part44.2similar to the connection part shown inFIG.6may be provided at a side wall of the connection buffering member44, and is used to form hook engagement with an inner wall of a case42.

However, a locating buffering member53and a support buffering member55are not provided on the connection buffering member44, rather they are provided on a top wall and a bottom wall of a case52respectively. The locating buffering member53and the support buffering member55are configured as tapered buffering members, so that point contact or line contact is formed between them and the case52.

FIG.9illustrates a blower device60according to a sixth embodiment of the present invention. In this embodiment, a case62is configured to include an upper case62.1and a lower case62.2. A locating buffering member63is disposed on a top wall of the upper case62.1, and has point contact or line contact with a top wall of a box-shaped connection buffering member64. A support buffering member65is connected to a bottom wall of the connection buffering member64via a buffering block65.1, and a bottom surface of the buffering block65.1is connected to bottom wall buffering members65.2which each has gradually reduced cross-section toward a bottom wall of the lower case62.2. Preferably, the buffering block65.1and the bottom wall buffering members65.2are formed integrally.

Moreover, point contact or line contact is formed between each of the bottom wall buffering members65.2and the bottom wall of the lower case62.2. The connection buffering member64also comprises a connection part64.2extended horizontally from the side wall of the connection buffering member64, and the connection part64.2is pressed between engagement surfaces of the upper case62.1and the lower case62.2.

FIG.10illustrates a blower device70according to a seventh embodiment of the present invention. In this embodiment, the blower device70includes a locating buffering member73similar to that according to the first embodiment, however it doesn't include a connection buffering member. In addition, the blower device70includes support buffering members75extended outwards from a bottom surface of a blower vibration source71. The support buffering members75each includes a support pillar75.1extended through a case72and a support leg75.2disposed at a free end of a side of the support pillar75.1which is outside the case72. In order to prevent each of the support buffering members75from dropping out from the case72, a clamping block75.3is provided at another side of the support pillar75.1which is inside the case72. In this embodiment, buffering members72.1which are made of, for example, silicon are respectively provided at places through which the support pillars75.1pass the case72. And there is a small gap between each of the buffering members72.1and the respective clamping block75.3and/or the respective support leg75.2, so that a better buffering function is provided.
