[0016] Attached Figure 2 This is a schematic diagram of the reverse structure of the tray;

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] As attached Figures 1 to 3 The tray 1 for cleaning the pressure-sensitive membrane is divided into a front side and a back side, and the front side of the tray 1 is provided with a plurality of placement grooves 2, and the pressure-sensitive membrane can be placed in the placement grooves 2. The plurality of placement grooves 2 on the tray 1 are divided into multiple rows, and the placement grooves 2 in the same row are arranged linearly.

[0020] The front of the tray 1 is also provided with a plurality of guide grooves 3, which start from one side edge of the tray 1, pass through each placement groove 2 in the same row one by one, and extend to the opposite side edge of the tray 1. Figure 1 As shown in the figure, the guide groove 3 passes through each placement groove 2 in the same row one by one, and it is shaped like a candied haws. The two ends of the guide groove 3 are respectively located on the opposite side edges of the tray 1, so that the water flow can pass through each placement groove 2 in the same row in sequence along the guide groove 3. Therefore, when the trays 1 are stacked with their front faces facing up, the two adjacent trays 1 fit each other, making the space occupied by the stacked trays 1 smaller. Due to the existence of the guide groove 3, there is a space between the two trays 1 that fit each other to guide the water flow, and the water flow can pass through the space between the two adjacent trays 1 along the guide groove 3 to clean the pressure-sensitive diaphragm in the placement groove 2.

[0021] The bottom of the placement groove 2 has a through hole 4, which passes through the front and back sides of the tray 1. The area of ​​the through hole 4 is smaller than the area of ​​the pressure-sensitive membrane. When the pressure-sensitive membrane is placed in the placement groove 2, it will not fall out of the through hole 4. Due to the existence of the through hole 4, the bottom surface of the pressure-sensitive membrane can be exposed to the back side of the tray 1 through the through hole 4, so when the water flows through two adjacent trays 1 along the guide groove 3, the water can pass through the through hole 4 to clean the bottom surface of the pressure-sensitive membrane.

[0022] A plurality of guide grooves 3 are also provided on the back side of the tray 1, and the guide grooves 3 on the back side of the tray 1 correspond one to one with the guide grooves 3 on the front side of the tray 1. Figure 1 and 2 As shown in , the guide grooves 3 on the front and back sides of the tray 1 correspond to each other, and their positions are relatively corresponding. The width of the guide groove 3 on the back side is slightly larger than the width of the guide groove 3 on the front side, and the width of the guide groove 3 on the front side is smaller, so that the placement groove 2 can better limit the pressure-sensitive membrane. When the trays 1 are stacked together, the guide groove 3 on the back side of the tray 1 can be combined with the guide groove 3 on the front side of the adjacent tray 1 to form a larger guide gap, so that the water flow that can pass between the adjacent trays 1 is larger, and the cleaning effect is better.

[0023] As attached Figure 2 As shown in FIG. 1 , a handle groove 5 is provided on the reverse side of the tray 1. There are two handle grooves 5, which are respectively located at one side edge of the tray 1 corresponding to the starting point of the guide groove 3 and one side edge of the tray 1 corresponding to the end point of the guide groove 3, that is, the two handle grooves 5 are respectively located at both ends of the guide groove 3. When the trays 1 are stacked together, fingers can be inserted into the handle groove 5 to pick up the tray 1. In addition, since the handle groove 5 is located at the edge of the tray 1, the water flow entering the guide groove 3 can be increased to a certain extent.

[0024] The pallet 1 is provided with a positioning block 6 and a positioning groove 7. When the pallets 1 are stacked, the positioning block 6 is plugged into and matched with the positioning groove 7 on the adjacent pallet 1 to position the stacked pallets 1 so that the pallets 1 can be neatly stacked together. Figure 1 and 2 As shown in , the positioning block 6 is arranged on the front side of the tray 1, and the positioning groove 7 is arranged on the back side of the tray 1. When the trays 1 are stacked together with the front side facing up, the back side of the tray 1 on the bottom layer faces down. Since there is a positioning groove 7 instead of a positioning block 6 on the back side of the tray 1, the back side of the tray 1 can directly contact the support surface, so that the stacked trays 1 can be placed on the support surface more stably. Specifically, the tray 1 is a rectangular tray body, and the positioning blocks 6 and the positioning grooves 7 are arranged at two diagonal corners of the tray 1. The two groups of positioning blocks 6 and positioning grooves 7 can have a better positioning effect, and will not affect the layout of the placement grooves 2 on the tray 1 at the diagonal corners, and the structural arrangement is more reasonable.

[0025] The contour shape of the placement groove 2 is consistent with the contour shape of the pressure-sensitive diaphragm, so that the pressure-sensitive diaphragm can be placed in the placement groove 2 with a limited position, and the pressure-sensitive diaphragm is prevented from moving randomly in the placement groove 2. Specifically, the pressure-sensitive diaphragm is circular, and there is a groove on the edge of the pressure-sensitive diaphragm. Correspondingly, the placement groove 2 is a circular groove, and a limited position convex point 8 is set in the placement groove 2. When the pressure-sensitive diaphragm is placed in the placement groove 2, the limited position convex point 8 is correspondingly inserted into the groove, so that the pressure-sensitive diaphragm will not rotate in the placement groove 2.

[0026] The placement slots 2 in two adjacent rows on the tray 1 are arranged in a staggered manner, so that more placement slots 2 can be arranged on the tray 1.

[0027] Combined with Figure 3 , the working method of the utility model is explained as follows: the pressure-sensitive diaphragm is placed in the placement groove 2 on the tray 1, and then the trays 1 are stacked together and placed in the cleaning basket 9, and then the cleaning basket 9 is placed in the ultrasonic cleaning tank, and the water flows along the extension direction of the guide groove 3 in the tray 1, and the dirt on the surface of the pressure-sensitive diaphragm is taken away under the action of the ultrasonic wave, and the floating dirt flows out through the overflow port in the cleaning tank, and the precipitated dirt sinks to the bottom of the cleaning tank.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
