[0001] The utility model relates to the technical field of water sample filtering, in particular to a water sample pre-treatment rapid filtering device. Background Art

[0002] At present, a water sample pretreatment device is a very common device in water sample pretreatment. It can treat water before testing the water sample. The filter element inside the filter device can quickly and efficiently filter out some impurities that affect the water sample detection, so as to facilitate subsequent analysis or detection, thereby improving the accuracy of water sample detection. However, most of the water sample pretreatment rapid filtration devices in the prior art still have problems that need to be solved during use.

[0003] In the prior art, the filter element in most of the water sample pretreatment rapid filtration devices is installed inside the filtration device by bolting.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
