Description

Technical Field

[0001] The utility model relates to sweet potato tissue culture seedling propagation equipment, belonging to the field of sweet potato seedling cultivation equipment. Background Art

[0002] Sweet potato is a perennial twining vine of the Dioscoreaceae family and the Dioscorea genus. The tuber has many branches at the top, the stem is left-handed, with thorns at the base and covered with T-shaped soft hairs; the leaves are heart-shaped, with long T-shaped soft hairs, especially on the back, and the petioles have thorns; the perianth is shallowly cup-shaped and covered with soft hairs; the fruit is less mature and triangular.

[0003] Therefore, the branch and leaf structure of sweet potato is more suitable for tissue culture bottles. The Chinese invention patent with application number CN202210635379.8 provides a method for efficiently expanding sweet potato tissue culture seedlings by stubble culture. According to its content, it can be known that the tissue culture seedlings use tissue culture bottles.

[0004] Tissue culture bottles usually use breathable caps, which are characterized by providing excellent ventilation characteristics, ensuring that the culture obtains sufficient oxygen and nutrients, while effectively preventing excessive accumulation of carbon dioxide during the culture process, which is beneficial to cell growth and division. However, breathable caps may cause dust containing bacteria to fall into the tissue culture bottles, so they usually need to be sterilized and dusted regularly.

[0005] The Chinese utility model patent with application number CN201821843171.0 provides a breathable tissue culture bottle. The patent sets a cylindrical through hole that runs through the inside and outside of the bottle in the middle part of the bottle cap, and then fills the cylindrical through hole with non-woven fabric and cotton; although such a setting can prevent pollution, dust will directly fall on the cylindrical through hole, and the service life is not long. Utility Model Content

[0006] The utility model aims to provide a sweet potato tissue culture seedling propagation device, which can effectively solve the above-mentioned problems.

[0007] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0008] The invention comprises a bottle body and a bottle cap arranged at the opening of the bottle body; a plurality of through grooves are arranged on the side of the bottle cap, and non-woven fabrics are arranged in the through grooves.

[0009] Further: the bottle cap is composed of a cover plate, a fastening ring and a guide ring arranged at the lower end of the cover plate; the guide ring is arranged outside the fastening ring, and a gas gap is arranged between the guide ring and the fastening ring; the through groove is arranged on the fastening ring.

[0010] Furthermore: a reinforcing rod is also arranged on the inner side of the guide ring, and one end of the reinforcing rod is connected to the outer side of the fastening ring.

[0011] Further: a through hole is arranged in the middle of the cover plate, and a rubber air seal is arranged in the through hole.

[0012] Furthermore: the non-woven fabric in the through groove is arranged as a double layer, and cotton is filled between the two layers of non-woven fabric.

[0013] Furthermore: the bottle body is made of transparent glass material.

[0014] Furthermore: scale lines are provided on the outer wall of the bottle body.

[0015] The beneficial effects are:

[0016] The bottle cap is composed of a cover plate, a fastening ring and a guide ring arranged at the lower end of the cover plate; the guide ring is arranged outside the fastening ring, and a gas gap is arranged between the guide ring and the fastening ring; and the through groove is arranged on the fastening ring.

[0017] At the same time, the device uses a guide ring to cover the through groove of the fastening ring to prevent lateral dust from adhering to the non-woven fabric; the gas enters the gas gap between the guide ring and the fastening ring through the non-woven fabric, and finally realizes the gas exchange inside and outside the bottle; the carbon dioxide in the bottle comes out and the external oxygen is replenished in, which does not affect the air permeability of the entire device.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0026] See also Figure 1-4 This is an embodiment of a sweet potato tissue culture seedling propagation device of the utility model.

[0027] The bottle cap 2 comprises a bottle body 1 and a bottle cap 2 arranged at the opening of the bottle body 1 ; a plurality of through grooves 3 are arranged on the side of the bottle cap 2 , and non-woven fabrics 4 are arranged in the through grooves 3 .

[0028] The through groove 3 of the device is arranged on the side of the bottle cap 2, and a non-woven fabric 4 is arranged in the through groove 3, so that dust can be prevented from directly falling on the non-woven fabric 4. Compared with the prior art, the service life is longer.

[0029] The bottle cap 2 is composed of a cover plate 21 , a fastening ring 22 and a guide ring 23 arranged at the lower end of the cover plate 21 ; the guide ring 23 is arranged outside the fastening ring 22 , and a gas gap 24 is arranged between the guide ring 23 and the fastening ring 22 ; the through groove 3 is arranged on the fastening ring 22 .

[0030] At the same time, the device uses a guide ring 23 to cover the through groove 3 of the fastening ring 22 to prevent lateral dust from adhering to the non-woven fabric 4; and the gas enters the gas gap 24 between the guide ring 23 and the fastening ring 22 through the non-woven fabric 4, and finally realizes the gas exchange inside and outside the bottle; the carbon dioxide in the bottle comes out and the external oxygen is replenished in, which does not affect the air permeability of the entire device.

[0031] A reinforcing rod 25 is also provided inside the guide ring 23 , and one end of the reinforcing rod 25 is connected to the outside of the fastening ring 22 .

[0032] The reinforcing rod 25 of the device is used to connect the guide ring 23 and the fastening ring 22 together. Because when tightening the bottle cap 2, a force needs to be applied to the guide ring 23, and the guide ring 23 will deform without support, and the reinforcing rod 25 provides the required support for the guide ring 23.

[0033] A through hole is provided in the middle of the cover plate 21, and a rubber air seal 26 is provided in the through hole.

[0034] The main function of the rubber air seal 26 of the device is to inject the culture solution into the bottle by using a syringe; when the rubber air seal 26 is not used, the gas cannot pass through.

[0035] The non-woven fabric 4 in the through groove 3 is arranged as a double layer, and cotton 5 is filled between the two layers of the non-woven fabric 4 .

[0036] The double-layer non-woven fabric 4 plus cotton 5 is breathable and can filter out more dust.

[0037] The bottle body 1 is made of transparent glass material.

[0038] It is convenient to observe the growth status of sweet potato seedlings.

[0039] The outer wall of the bottle body 1 is provided with scale lines 6 .

[0040] The scale line 6 can be used to observe the liquid amount of the culture solution in the bottle, which is convenient for reminding the staff to replenish it in time.

[0041] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
