Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, and in particular to a novel water-retaining membrane structure. Background Technology

[0002] Edible fungi are currently cultivated using spawn bags. However, edible fungi require aerobic respiration and need to inhale external air. Existing spawn bags have holes in them and an air-intake membrane is placed over these holes. However, before the spawn is placed into the spawn bag, it needs to be placed inside a water-retaining membrane for cultivation. This prevents moisture loss during the cultivation process. However, the membrane can easily block the holes in the spawn bag, preventing air from entering the spawn bag to provide oxygen to the spawn. Utility Model Content

[0003] The purpose of this invention is to provide a novel water-retaining membrane structure that can solve the problem that the membrane cloth of the water-retaining membrane will block the pores of the inoculum bag, thus ensuring that air can enter the inoculum bag.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel water-retaining membrane structure, comprising a water-retaining membrane body, wherein the water-retaining membrane body is provided with an array of air-permeable holes.

[0005] Furthermore, the ventilation holes are provided in two or more rows, with each row having two or more ventilation holes.

[0006] Furthermore, the diameter of the vent hole is 0.1-0.5 mm.

[0007] Furthermore, the single-row and double-row air vents are arranged alternately.

[0008] Furthermore, the vent holes are arranged in a circular array.

[0009] Furthermore, the single-row and double-row ventilation holes are aligned.

[0010] Furthermore, the water-retaining membrane body is provided with an adjustment component.

[0011] Furthermore, the adjustment component includes an annular channel, a first pull rope, and a first straight channel. The annular channel is disposed around the vent hole, and two outlets are provided at the upper end of the annular channel. The straight channel is disposed above the annular channel, and the outlets are connected to the straight channel. The first pull rope is sleeved inside the first straight channel and the annular channel, and both ends of the pull rope are located outside the first straight channel.

[0012] Furthermore, the adjustment component includes a limiting channel, a second straight channel, and a waterproof sheet. The limiting channel is disposed on both sides of the vent hole, and the second straight channel is disposed above the limiting channel and connected to the limiting channel. The two ends of the waterproof sheet are respectively located in the limiting channels on both sides. One end of the second pull rope is fixed to the end of the waterproof sheet, and the other end passes through the second straight channel and is located outside the second straight channel.

[0013] The beneficial effects of this utility model are as follows: The array of vents in this utility model is aligned with the pores on the spawn bag, so that even if the water-retaining membrane is pressed against the spawn bag, the vents and the pores on the spawn bag are still connected. Air can still enter through the water-retaining membrane to replenish oxygen for the spawn inside the waterproof bag. This solves the problem of the water-retaining membrane blocking the pores of the spawn bag, ensuring that air can enter the spawn bag and improving the survival rate of the spawn.

[0023] The present invention will be further described below with reference to the accompanying drawings. For better understanding, the orientation of the present invention is described based on the orientation shown in the accompanying drawings and should not be construed as a limitation of this application; the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Please see Figures 1 to 8 This utility model provides an embodiment: a novel water-retaining membrane structure, including a water-retaining membrane body 1, on which an array of air vents 2 are arranged. The array of air vents 2 on the water-retaining membrane body 1 is aligned with the pores on the inoculum bag, so that even if the membrane of the water-retaining membrane is pressed against the inoculum bag, the air vents 2 and the pores on the inoculum bag remain connected, allowing air to enter through the water-retaining membrane to replenish oxygen for the inoculum inside the waterproof bag.

[0025] Please continue reading. Figures 1 to 5 As shown in one embodiment of this utility model, the ventilation holes 2 are arranged in two or more rows, with each row having two or more ventilation holes 2. The number of ventilation holes can be set according to the habits of the fungal species.

[0026] Please continue reading. Figures 1 to 6 As shown, in one embodiment of this utility model, the diameter of the vent hole 2 is 0.1-0.5mm.

[0027] Please continue reading. Figure 3 As shown, in one embodiment of the present invention, the single-row air vents 2 and the double-row air vents 2 are arranged alternately.

[0028] Please continue reading. Figure 4 As shown, in one embodiment of this utility model, the vent holes 2 are arranged in a circular array.

[0029] Please continue reading. Figure 1 , Figure 2 As shown, in one embodiment of this utility model, the single-row air vents 2 and the double-row air vents are aligned.

[0030] Please continue reading. Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in one embodiment of the present invention, an adjustment component 3 is provided on the water-retaining membrane body 1. The adjustment component 3 can adjust the amount of air permeable through the air vents 2.

[0031] Please continue reading. Figure 4 , Figure 6As shown in one embodiment of the present invention, the adjusting component 3 includes an annular channel 33, a first pull cord 31, and a first straight channel 32. The annular channel 33 is disposed around the air vent 2, and has two outlets at its upper end. The straight channel is disposed above the annular channel 33, and its outlets are connected to the straight channel. The first pull cord 31 is sleeved within the first straight channel 32 and the annular channel 33, with both ends of the pull cord located outside the first straight channel 32. The first pull cord 31 is positioned outside the opening of the breathable bag through the first straight channel 32. By pulling the first pull cord 31, the membrane fabric containing the air vent 2 can be wrinkled, causing the air vent 2 to deform and reducing the amount of air passing through, thereby adjusting the amount of air passing through.

[0032] Please continue reading. Figure 6 , 8 As shown in one embodiment of this utility model, the adjusting component 3 includes a limiting channel 34, a second straight channel 35, and a waterproof sheet 36. The limiting channel 34 is disposed on both sides of the vent hole 2. The second straight channel 35 is disposed above the limiting channel 34 and communicates with it. The two ends of the waterproof sheet 36 are respectively located inside the limiting channels 34 on both sides. One end of the second pull rope 37 is fixed to the end of the waterproof sheet 36, and the other end passes through the second straight channel 35 and is located outside the second straight channel 35. The second pull rope 37 is placed outside the opening of the breathable bag through the second straight channel 35. By pulling the second pull rope 37, the waterproof sheet 36 can be moved to cover part of the vent hole 2, thereby adjusting the air permeability of the vent hole 2.

[0033] The present invention has the following working principle: the array of vent holes can be aligned with the holes on the inoculum bag, so that even if the membrane of the water-retaining film is squeezed onto the inoculum bag, the vent holes and the holes on the inoculum bag are still connected, and air can still enter through the water-retaining film to replenish oxygen for the inoculum inside the waterproof bag.

[0034] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
