M347966 八、新型說明： 【新型所屬之技術領域】 本創作涉及馬達技術領域’特指一種使用於碎紙機中，具有隔 音裝置的碎紙機馬達。 【先前技術】 為了避免機密性檔案或資料外茂落入不當人士手中，通常會利 用碎紙機加以雜。於是碎紙機便成為—種商務及居家生活不可 或缺的設備。 目前市場上所採用的是電動碎紙機，該電動碎紙機自交流馬達 驅動’該馬達轉子與碳刷之間為彈性接觸，因馬達轉子通過馬達 驅動作高舰轉，當馬達通電時，碳刷與馬達轉子之間的接 觸會導致噪音產生。 【新型内容】M347966 VIII. New description: [New technical field] This creation relates to the field of motor technology. Specifically, it refers to a shredder motor used in a shredder with a soundproofing device. [Prior Art] In order to prevent confidential files or data from falling into the hands of unscrupulous people, shredders are often used. The shredder has become an indispensable device for business and home life. At present, the electric shredder is used in the market. The electric shredder is driven by an AC motor. The motor rotor is in elastic contact with the carbon brush. Because the motor rotor is driven by the motor for high ship rotation, when the motor is energized, Contact between the carbon brush and the motor rotor can cause noise. [New content]

The motor for solving the above-mentioned technical problem includes: a Malay bracket, a motor rotor, and an elastic contact with the motor rotor, the motor further includes a cover motor rotor and a side wall external soundproofing cover, the soundproof cover includes The inner cover and the outer cover of the phase and the outer cover and the inner cover and the outer cover are respectively provided with the inner and outer covers of the sound-insulating army, and the outer cover and the outer cover are respectively provided with a (four) rail, and the shaft is replaced by the position The front end of the soundproof cover is sealed - the miscellaneous seal seals the rear end of the soundproof cover of the door of the motor rotor with the second seal to seal the gap between the rotor and the horse's rotor. /, there is a gap between the inner cover and the outer cover.缘疋' This creation uses the motor soundproof cover to rub the motor rotor and the motor against the brush, and when the secret rotor and the carbon thief produce (four) sound through the spacer hood, due to the sound hood between the inner cover and the outer cover The small holes are interlaced, and the sound waveform is disturbed, so the sound that is revealed is greatly _, from the sound of the sound. At the same time, too much is created, installed at the noise source, and its volume is small, which can reduce the cost of the product. In addition, = the effect of turning the fire, because the motor rotor and motor carbon brush friction position is easy = cremation 'wire is packaged, can be connected to the outside world to fire. As mentioned above, this creation has many advantages such as high structural simplicity and practicability compared to current products, and has a large market competition/low queen [implementation] related to this feature, thief _ and best implementation The details are as follows: As shown in Figure 1, 2, and 3, the motor of this creation includes · motor rear bracket, for reverse: 3 solid reading 2, carbon brush 3, motor rotor 5, and a motor soundproof cover 7 : The Γ 7 can attenuate the noise generated by the friction between the motor rotor 5 and the carbon brush 3 from the contact between the rotor 5 and the carbon brush 3, and reduce the noise during the operation of the mouth. Among them, the soundproof cover 7 of the motor is snapped over the motor rotor 5 and the carbon is turned over (10)©. The soundproof cover 7 includes an inner cover 71 and a cover 72 which are sleeved on each other, and the inner M347966 cover 71 and the outer cover 72 are provided with small (four) and melon which are interlaced. Further, there is a constant gap between the inner cover 71 and the outer cover 72. The sunshade cover 7_ cover 71 and the outer cover 72 are both annular, and a through hole W is formed in the position corresponding to the carbon brush 3, that is, the through hole 3 passes through the through hole claw, 722 and the motor rotor 5 contact.
所述的隔曰罩7中内罩71的前端通過第—彈性密封件*將其 與馬達轉子5之間的間隙密封，所述的隔音罩7的内罩71後端通 過第二密封件8將其與馬達轉子5之間_ _封，_ Μ的後 端面形成有一凹槽713，環形的第一密封件8位於該凹槽内； 上述的彈性密封件可採膠、歸材料製作。 於碳刷3外設置有一彈簧’該彈簧將馬達碳刷3壓在馬達轉子 5上’使碳刷3與馬達轉子5緊密接觸。The front end of the inner cover 71 of the barrier cover 7 is sealed by a first elastic seal* to a gap between the motor rotor 5, and the rear end of the inner cover 71 of the soundproof cover 7 passes through the second seal 8 A rear end surface of the motor rotor 5 is formed with a groove 713, and the annular first sealing member 8 is located in the groove; the elastic sealing member can be made of rubber and material. A spring is disposed outside the carbon brush 3, and the spring presses the motor carbon brush 3 against the motor rotor 5 to bring the carbon brush 3 into close contact with the motor rotor 5.
結上可知，本卿细馬達隔音罩7將馬達轉子$與馬達碳刷 3摩擦位置職起來，#馬雜子5與伽3接觸位置所產生的噪 音在穿過隔音罩7時，由於隔音罩7内罩71與外單72之間的小 孔711 721相互义錯，音波形成干擾，所以透出的聲音被大大減 弱，從而達職音效果’叫足消轉求，時’本創作僅安裝 在嗔音源處，其體積較小’可降低產品成本。另外，本創作還且 有防火效果，祕馬猶子5與馬辆刷3摩擦健容易因打火 形成“ ’將此_裝起來’可避免火花與外界接觸引發火災。 綜上所述，本創作相對目前的產品具有結構簡單、噪音低，安 全性高、實雜鮮諸多優點，具有較大的市場競爭力。 6 M347966 本創作之技術內容及技術特點巳揭示如上，然而熟悉本項技術 之人士仍可能基於本創作之揭示而作各種不背離本案創作精神之 替換及修飾。因此，本創作之保護範圍應不限於實施例所揭示者， 而應包括各種不背離本創作之替換及修飾，並為以下之申請專利 範圍所涵蓋。 【圖式簡單說明】 圖1係本創作的立體圖； 圖2係本創作之刮視圖； 圖3係本創作局部立體分解圖。 【主要元件符號說明】 1 馬達後支架 2 固定件 3 碳刷 4 第一彈性密封件 5 馬達轉子 7 馬達隔音罩 71内罩 711小孔 712通孔 713凹槽 72外罩 721小孔 M347966 722通孔 8 第二密封件It can be seen that the fine motor soundproof cover 7 of the present invention rubs the motor rotor $ with the motor carbon brush 3, and the noise generated by the contact position of the #马杂子5 and the gamma 3 passes through the soundproof cover 7 due to the soundproof cover. 7 The small hole 711 721 between the inner cover 71 and the outer single block 72 is mutually wrong, and the sound waves form interference, so the sound that is transmitted is greatly weakened, so that the sound effect of the job is called "sufficiently, and the creation" is only installed. At the source of the sound, its small size can reduce the cost of the product. In addition, this creation also has a fireproof effect. The secret horse is still rubbed with the horse brush 3 and it is easy to form a fire by “making this _ put up” to avoid the spark from contacting the outside world and causing a fire. In summary, this creation Compared with the current products, it has the advantages of simple structure, low noise, high safety, and many common advantages. It has great market competitiveness. 6 M347966 The technical content and technical characteristics of this creation are as disclosed above, but those who are familiar with the technology It is still possible to make various substitutions and modifications based on the disclosure of the present invention without departing from the spirit of the present invention.
