(1)看清潔效果(重要)

(1) Check the cleaning effect (important)

考察超聲波清洗機（jī）清（qīng）潔效果好不好得看兩個點!一個是超（chāo）聲波（bō）振（zhèn）動頻率、一個是額定（dìng）功率!

There are two things to consider when evalsuating the cleaning effect of ultrasonic cleaning machines! One is the ultrasonic vibration frequency, and the other is the rated power!

①超聲波振（zhèn）頻:人耳可以聽到的聲音（yīn）頻率範圍在20Hz到20kHz之間。而家用（yòng）超聲波清洗機的頻率範圍全都超過20KHz以上,多為30kHz-50kHz不止!在選購的時候並不是振頻越高（gāo）越好。一（yī）般建議是在42kHz-48kHz這（zhè）個範圍內為最佳!低於42kHz會影響清洗效果,高於（yú）49000kHz則（zé）會對一些硬度不高的物品清洗存在限製!

① Ultrasonic vibration frequency: The frequency range of sound that can be heard by the human ear is between 20Hz and 20kHz. The frequency range of household ultrasonic cleaning machines all exceeds 20KHz, mostly ranging from 30kHz to 50kHz! When making a purchase, it is not necessarily better to have a higher vibration frequency. The general recommendation is that the optimal range is between 42kHz and 48kHz! A frequency lower than 42kHz will affect the cleaning effect, while a frequency higher than 49000kHz will limit the cleaning of some items with low hardness!

②額定功率:額定功（gōng）率指的是機械（xiè）設備所能達到的最大輸出功率!而家用型超聲波（bō）清洗機額定功率大多在（zài）10W-70W不止。一般是15W-30W這個範圍內就夠用了。額定功率過高,對於一些比如（rú）玉石或是手鐲之（zhī）類的清洗容易造（zào）成損壞。

② Rated power: Rated power refers to the maximum output power that mechanical equipment can achieve! The rated power of household ultrasonic cleaning machines is mostly between 10W-70W. Generally, the range of 15W-30W is sufficient. Excessive rated power can easily cause damage to cleaning items such as jade or bracelets.

(2)看材（cái）質(主要)

(2) Look at the material (main)

相信（xìn）在網上也會看見過有（yǒu）人買過幾塊錢、十幾塊（kuài）錢的超聲波清洗機,這種在使用（yòng）上（shàng）麵,除了浪費十幾塊（kuài）錢之外,沒有任何作用!

I believe you have also seen people online who have bought ultrasonic cleaning machines for a few or even a dozen yuan. These machines have no effect in use except for wasting more than ten yuan!

首先在材質上,它采用的是廉價的（de）塑料材質,用久之後發（fā）熱發燙甚至變型!

Firstly, in terms of material, it uses inexpensive plastic material, which can heat up and even transform after prolonged use!

而真正的超聲波清洗機內膽都是采用的304不鏽鋼設計,以及外殼（ké）采用了不易變型的ABS材質!內膽（dǎn）更耐腐蝕、外殼更耐用!一個機子使用（yòng）壽命也好幾年!

And the real ultrasonic cleaning machine uses 304 stainless steel design for the inner liner, and the outer shell is made of ABS material that is not easily deformed! The inner liner is more corrosion-resistant and the outer shell is more durable! A machine has a lifespan of several years!

(3)看使（shǐ）用感受（shòu）(次要)

(3) Viewing user experience (secondary)

超（chāo）聲波清洗機除了在清潔力方麵表現過關之外,在機器使用清洗、或（huò）是清洗體驗上麵,也需要注重一下!比如機器清洗檔位、能否多物件同時（shí）清洗、清洗操作是（shì）否簡單等!

In addition to performing well in terms of cleaning power, ultrasonic cleaning machines also need to pay attention to their use and cleaning experience! For example, the machine cleaning gear, whether multiple objects can be cleaned simultaneously, and whether the cleaning operation is simple!

①清（qīng）洗檔位（wèi）:比如有些機器支持多模式清洗,這（zhè）種在清洗上麵能夠分類清洗物品,提高清洗效率!

① Cleaning gear: For example, some machines support multi-mode cleaning, which can classify cleaning items and improve cleaning efficiency!

②可視化上蓋:有些機（jī）器會采用可視的（de）頂蓋設計,比如一些需要（yào）蓋上蓋子才能進行除菌模式的,可（kě）視（shì）化的設計能夠讓用戶更加清晰的觀（guān）察（chá）物品清洗狀態!

② Visual top cover: Some machines may adopt a visual top cover design, such as those that require a lid to perform sterilization mode. The visual design allows users to observe the cleaning status of items more clearly!

③操作使用:比如（rú）一些機（jī）器會（huì）設計一鍵開啟模式,開機即用,對於新手小白來（lái）講上手操作也（yě）比較輕（qīng）鬆（sōng）!

③ Operation and use: For example, some machines will be designed with a one click start mode, which is easy to use for beginners!

④多物件清洗:有些隻支持獨類的物品清洗,比如（rú）牙套（tào）的隻能清洗牙套、隱形（xíng）眼鏡的隻能（néng）清洗隱形眼鏡。而有些事能夠清洗眼鏡、牙套、化妝刷等等物品!

④ Multi object cleaning: Some only support cleaning of unique items, such as braces that can only be cleaned, and contact lenses that can only be cleaned. And some things can clean items such as glasses, braces, makeup brushes, and so on!

⑤噪音（yīn）:超聲波洗眼鏡機在清洗過程中是會（huì）出現一些聲響的!在選購的時候,如（rú）果是喜歡安（ān）靜的,可以選擇噪音小的!這（zhè）個按個人接受程度選購即（jí）可（kě）!

⑤ Noise: There may be some noise during the cleaning process of the ultrasonic eyewash machine! When making a purchase, if you prefer quiet, you can choose one with low noise! You can choose this according to your personal acceptance level!

⑥重量:家用型超聲（shēng）波清洗機也（yě）有很多（duō）款式,大多（duō）數的設計都比較輕便易於攜帶（dài）,而有些的重（chóng）量也相對會比較重一些,如果是考慮到出門（mén）也會攜帶的話,就經理選擇重（chóng）量（liàng）不那麽（me）重的,放進包裏（lǐ）就能帶走!

⑥ Weight: There are also many styles of household ultrasonic cleaning machines, most of which are designed to be lightweight and easy to carry, while some are relatively heavier. If you consider carrying them when going out, the manager will choose a less heavy one, which can be taken away by putting it in the bag!

(4)附加功能 (其次)

(4) Additional features (second)

雖然超聲波清洗（xǐ）機有很多,但是支持除菌的卻寥寥無幾!要比較起（qǐ）來,超聲波清洗機（jī）帶有除菌功能的會比沒有除菌功能的清洗效果（guǒ）更加好一點!

Although there are many ultrasonic cleaning machines, there are very few that support sterilization! Compared to those without sterilization function, ultrasonic cleaning machines with sterilization function will have a better cleaning effect!

所以在選購的時候,可（kě）以盡量選擇帶有除菌的超聲波（bō）洗眼鏡機!這樣在對於眼鏡上麵的細（xì）菌清洗時也能發（fā）揮（huī）作用,不需要額外購（gòu）買除菌劑!

So when choosing, you can try to choose an ultrasonic eyewash machine with sterilization as much as possible! This can also be effective in cleaning bacteria on glasses without the need to purchase additional antibacterial agents!
