And a fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected to the interior of the fixing box, a blocking plate is fixedly connected to the bottom of the sliding plate, and the bottom of the blocking plate abuts against the top of the limiting block. According to the filter element replacing device, the pin rod is pulled outwards through the handle, so that the pin rod drives the limiting block to compress the spring to retract into the mounting shell, and the baffle is pulled up through the sliding plate after a new filter rod is replaced, so that the operation efficiency of replacing the filter element is improved, and the operation convenience is improved.

The utility model belongs to the technical field of blueberry planting, and provides a blueberry planting irrigation device which comprises a water tank, an irrigation water pipe, a planting pot and an alternate irrigation mechanism. The water tank is communicated with the alternate irrigation mechanism through an output pipe, and a water pump is arranged on the output pipe; the alternate irrigation mechanism is communicated with the multiple irrigation water pipes, the multiple planting pots are arranged in the direction of the irrigation water pipes, and the irrigation water pipes are communicated with the planting pots through branch pipes; the alternate irrigation mechanism is used for alternately supplying water to the plurality of irrigation water pipes in sequence; the water absorption efficiency of soil can be improved in a spaced irrigation mode, and the situation that due to the fact that too much water accumulates on the surface layer of the soil, water drainage is unsmooth, and respiration and growth of blueberry roots are affected is avoided.

This utility model discloses a sandwich-type cold compress eye mask, including an eye mask body. Inside the eye mask body, there are sequentially arranged a first layer of hot-air cotton non-woven fabric, a second layer of cold compress material, a third layer of hot-air cotton non-woven fabric, and a fourth layer of freeze-dried film. The first layer of hot-air cotton non-woven fabric, the second layer of cold compress material, and the third layer of hot-air cotton non-woven fabric form a sandwich structure. The second layer of cold compress material covers the entire gap between the first layer of hot-air cotton non-woven fabric and the third layer of hot-air cotton non-woven fabric. Adjacent layers of the first layer of hot-air cotton non-woven fabric, the second layer of cold compress material, and the third layer of hot-air cotton non-woven fabric are fixed by any one of the following methods: hot pressing, needle punching, or ultrasonic treatment.
