Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model.

[0030] The technical solutions of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation. The same or similar concepts or processes may not be repeated in some embodiments.

[0031] As Figures 1 to 8 shown, the present utility model provides an edible mushroom cultivation bottle, which includes a bottle body 1 and a bottle cap 2. The bottle cap 2 includes a lower cover 21, a middle cover 22, an upper cover 23, and an air filter membrane 24 provided in the upper cover 23. The bottle body 1 is used to hold the edible mushroom culture medium. The bottle cap 2 is covered at the bottle mouth of the bottle body 1. The bottle cap 2 and the air filter membrane 24 on the bottle cap 2 are used to provide a sealed environment for the culture medium in the bottle body 1, prevent miscellaneous bacteria from invading the cultivation bottle and competing for resources with the edible mushrooms, and at the same time play a role in regulating gas exchange, which can not only discharge the waste gas generated by the growth of the edible mushrooms, but also introduce fresh air to meet their breathing and metabolic needs.

[0032] The lower cover 21 is used to cover at the bottle mouth of the bottle body 1. The lower cover 21 is circular. When the lower cover 21 is covered at the bottle mouth, a surface close to the bottle mouth is provided with an inhibition platform 212. The inhibition platform 212 and the lower cover 21 are concentric cylinders. The diameter of the circular surface of the inhibition platform 212 is 2 - 4 cm smaller than the diameter of the bottle mouth. When the lower cover 21 is covered at the bottle mouth, the inhibition platform 212 extends into the bottle mouth and closely adheres to the upper surface of the edible mushroom culture medium, but does not contact the edible mushroom culture soil, and is used to inhibit the growth of aerial hyphae and reduce the formation of old mycelial skins. Three fan-shaped first ventilation holes 211 are annularly and arrayedly distributed on the inhibition platform 212, and are used for gas exchange of the edible mushroom culture medium in the bottle body 1 to promote the growth of hyphae.

[0033] The middle cover 22 is the same as the lower cover 21 and is circular. The overall diameter of the middle cover 22 is the same as that of the lower cover 21. The upper top surface of the middle cover 22 is a circular arch. A second ventilation hole 221 is opened on the arched surface for installing the upper cover 23. The main body of the upper cover 23 is two hollow pipe bodies connected by threads. Preferably, the upper cover 23 is installed on the second ventilation hole 221 on the arched surface of the middle cover 22 at an inclined angle of 30°. The number of upper covers 23 is three and they are distributed in a circular array on the arched surface and are relatively close to the top of the arched surface. Designing the upper top surface of the middle cover 22 as an arched surface makes it more convenient for the upper cover 23 to be installed on the middle cover 22 in an inclined state, and the arched surface has a guiding effect on the air flow, making the air flow more easily concentrated at the position close to the arched surface and then discharged through the third ventilation hole 231 of the upper cover 23;

[0034] Preferably, the upper cover 23 with an inclined angle of 30° is provided on the second ventilation hole 221 of the middle cover 22. The upper cover 23 has a third ventilation hole 231. Due to the angle, the gas flowing out of the bottle body 1 will flow along the upper inner wall of the third ventilation hole 231 and be discharged from the gas exchange hole 234, while the amount of gas near the lower inner wall of the third ventilation hole 231 is small, and a negative pressure area will be formed between the upper inner wall and the lower inner wall. The negative pressure area will make the air around the gas exchange hole 234 more easily drawn into the negative pressure area, and more effectively promote the air exchange inside and outside the bottle body, which is helpful for the cultivation of edible fungi in the bottle body 1.

[0035] The rain cap 232 at the top of the upper cover 23 is fixed to the top of the upper cover 23 through three support plates 233 to prevent water from dripping into the bottle body 1 through the third ventilation hole 231.

[0036] Specifically, the lower cover 21 of the present utility model is designed to inhibit the growth of aerial hyphae. The inhibition platform 212 of the lower cover 21 extends into the bottle mouth and closely adheres to the upper surface of the edible fungus culture material, which can inhibit the growth of aerial hyphae, reduce the formation of old mycelial skins, provide a suitable environment for the growth of edible fungi, avoid nutrient waste, and improve the yield and quality. The three fan-shaped first ventilation holes on the inhibition platform 212 facilitate the gas exchange of the edible fungus culture material in the bottle body 1 and promote the growth of hyphae; the middle cover 22 is designed to guide the air flow. The circular arched upper top surface of the middle cover 22 can guide the air flow to be concentrated at the position close to the arched surface, improve the gas exchange efficiency, and create good ventilation conditions for the growth of edible fungi. It is convenient for the upper cover 23 to be installed at an inclined angle of 30° to play the air permeability function of the upper cover 23; the upper cover 23 is designed to promote air exchange. The inclined upper cover 23 makes the gas flowing out of the bottle body 1 flow along the upper inner wall of the third ventilation hole 231 and be discharged, and a negative pressure area is formed near the lower inner wall, which prompts the air around the gas exchange hole to be drawn into the negative pressure area, effectively promoting the air exchange inside and outside the bottle body, providing sufficient fresh air for the edible fungi, and promoting their growth and development. The overall design realizes the effective regulation of the humidity, temperature and gas components in the bottle body 1 through a reasonable ventilation hole layout and the design of the inclined upper cover 23, creates a stable and suitable environment for the cultivation of edible fungi, and improves the survival rate and quality of edible fungi.

[0037] like Figure 6 , Figure 7 and Figure 8 As shown, the preferred upper cover 23 is a structure that can be threadedly connected, namely a fixed column 235 and a disassembly cover 236. The fixed column 235 can be threadedly connected to the second air vent 221 of the middle cover 22 or made into an integral body. The fixed column 235 is a hollow cylinder with a thread on the outside. The disassembly cover 236 is a hollow cylinder that is threadedly connected to the fixed column 235. Furthermore, the top opening of the disassembly cover 236 is narrowed inwardly to provide a support platform for the air filter membrane 24 to prevent the air filter membrane 24 from being squeezed out from the top of the disassembly cover 236, thereby ensuring the stability of the installation of the air filter membrane 24. The air filter membrane 24 is loaded from the bottom of the disassembly cover 236 and the air filter membrane 24 is abutted against the top of the disassembly cover 236. The disassembly cover 236 is threadedly connected to the fixed column 235. The fixed column 235 will abut against the narrowed part of the top of the disassembly cover 236 to achieve extrusion and sealing of the side of the air filter membrane 24.

[0038] like Figure 6 and 7 As shown, the anti-rotation pin 237 at the bottom of the outer side of the preferred fixed column 235 is gradually raised in height in the tightening direction, and a limiting groove 238 matching the anti-rotation pin 237 is provided at the bottom inside the disassembly cover 236. After the disassembly cover 236 and the fixed column 235 are threadedly screwed, the limiting groove 238 at the bottom of the disassembly cover 236 will be embedded in the anti-rotation pin 237 at the bottom of the fixed column 235. Because the anti-rotation pin 237 is gradually raised in height in the tightening direction, it can prevent the disassembly cover 236 from rotating in the loosening direction, thereby ensuring the stability of the connection between the disassembly cover 236 and the fixed column 235.

[0039] like Figure 2 and Figure 4 As shown, the inner side of the preferred middle cover 22 is provided with a first reinforcing rib 222 extending from the side wall to the top surface, and the first reinforcing rib 222 is located on the inner wall between two adjacent second air holes 221; the first reinforcing rib 222 extends from the side wall of the middle cover to the arched top surface, forming a support structure inside the middle cover 22. This can effectively enhance the overall strength and rigidity of the middle cover 22, making it less likely to deform when subjected to external pressure or internal stress, and at the same time, the reinforcing rib can disperse stress to avoid local stress concentration causing the middle cover 22 to rupture. During transportation, handling or operation, the middle cover 22 may be subject to collision or vibration, and the reinforcing rib can increase the impact resistance of the middle cover 22 and reduce the risk of rupture.

[0040] like Figure 5As shown, preferably, the lower cover 21 has a first sunken groove 213 therein, the inhibiting platform 212 has a second sunken groove 214, the first sunken groove 213 communicates with the second sunken groove 214, and a second reinforcing rib 215 is provided in the first sunken groove 213 and the second sunken groove 214; forming the sunken grooves can reduce the weight and material consumption of the lower cover 21, saving production costs. The second reinforcing rib 215 is provided in the first and second sunken grooves 214. The second reinforcing rib 215 is a triangular reinforcing rib, and the triangular reinforcing rib further enhances the structural strength of the sunken groove area, and can effectively prevent the lower cover 21 and the inhibiting platform 212 from deforming or cracking when stressed.

[0041] As Figure 3 shown, preferably, a first clamping strip 3 is provided on the outer wall of the bottle mouth, and a first clamping tooth 31 is provided on the inner wall of the lower end of the lower cover 21. The lower cover 21 is buckled outside the bottle mouth; a second clamping strip 4 is provided on the outer wall of the upper end of the lower cover 21, and a second clamping tooth is provided on the inner wall of the lower end of the middle cover 22. The middle cover 22 is buckled outside the lower cover 21; through the first clamping strip 3 and the first clamping tooth 31, the lower cover 21 can be firmly fixed on the bottle body 1 and will not be displaced or fall off easily. The second clamping strip 4 and the second clamping tooth 41 of the middle cover 22 also play a role in firmly fixing the middle cover 22 on the lower cover 21. Among them, the lower cover 21 is buckled outside the bottle mouth, which can effectively prevent water from flowing into the bottle body 1. Similarly, the middle cover 22 is buckled outside the lower cover 21 to prevent water from flowing into the bottle body 1.

[0042] As Figures 1 to 8 shown, an edible fungus cultivation bottle includes a bottle cap 2 and a bottle body 1. The bottle body 1 is used for containing an edible fungus culture medium. When the bottle cap 2 is closed at the bottle mouth of the bottle body 1, the inhibiting platform 212 is accommodated in the bottle mouth of the bottle body 1, and the side wall is adjacent to the inner wall of the bottle mouth of the bottle body 1, and is used to be adjacent to the edible fungus culture medium in the bottle body 1, so as to better inhibit the growth of aerial hyphae and prevent water loss in the edible fungus cultivation bottle.

[0043] In addition to the above preferred embodiments, the present invention has other implementation manners. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope claimed by the present invention.
