Description

Technical Field

[0001] The utility model relates to the technical field of mushroom houses, in particular to a positive pressure exhaust valve with a sunshade for an edible mushroom house. Background Art

[0002] Traditional edible fungi production in my country mostly utilizes greenhouses or simple fruiting houses as cultivation sites. These methods employ crude and unrefined management methods, making it difficult to precisely control various environmental factors essential for fungi growth, such as temperature, humidity, ventilation, and light. This makes it difficult to precisely control the growth envelope, resulting in susceptible contamination and low survival rates. Consequently, traditional edible fungi production in my country suffers from small scale, low yields, and poor stability. With the continuous development of intelligent factory-based control of edible fungi production, the need for refined control of the fungus house environment is gaining increasing attention.

[0003] Ventilation and exhaust management is crucial in the cultivation of edible mushrooms. To conveniently and accurately provide fresh air to the mushroom house and regulate carbon dioxide concentrations, edible mushroom houses typically use blowers to deliver fresh air, while exhaust fans or vents are used to expel carbon dioxide. This method meets the ventilation needs of edible mushroom growth.

[0004] Traditional exhaust vents are simple and simplistic, consisting of single louvers without insect screens. Small animals like insects and mice can enter the mushroom house through these louvers, failing to provide waterproofing or insect protection. They only provide simple ventilation. During storms, rainwater can easily flow into the room, failing to provide rain protection. Furthermore, this method can cause backflow, preventing the timely removal of carbon dioxide and other waste gases produced during mushroom growth, which can lead to the death of young mushrooms or the formation of deformed mushrooms, resulting in reduced yields. Furthermore, exhaust vents are prone to light transmission, while mycelial growth of edible mushrooms like king oyster mushrooms, shiitake mushrooms, oyster mushrooms, and black fungus does not require light, and light can actually inhibit mycelial growth. Therefore, existing exhaust vents are no longer suitable for the industrialized growth environment of edible mushrooms. Utility Model Content

[0005] In order to solve the problem that the existing exhaust vents in the prior art are no longer suitable for the environment required for the factory growth of edible fungi, the purpose of the utility model is to provide a positive pressure exhaust valve with a sunshade for an edible fungus house, which can immediately discharge the exhaust gas in the mushroom house, position the room in a positive pressure state, and reduce the impact of the external environment on the growth of mycelium.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a positive pressure exhaust valve with a sunshade for an edible mushroom house, comprising a valve plate, a sunshade and a plurality of blades;

[0007] The valve plate is provided with an exhaust hole; multiple blades are arranged up and down, with the top of the blade being rotatably connected to the valve plate, and the bottom of the blade resting on the blade or valve plate below it; when two adjacent blades are placed together, the multiple blades block the exhaust hole of the valve plate; when the two adjacent blades are separated, the exhaust hole of the valve plate is opened;

[0008] The sun visor includes a top cover part and two side stop parts. The top cover part is located between the two side stop parts and is fixedly connected to the side stop parts. The top cover part and the two side stop parts are both fixedly connected to the valve plate. The position where the top cover part is connected to the valve plate is above the exhaust hole, and the exhaust hole is located between the two side stop parts.

[0009] Preferably, the top cover is arc-shaped and the side baffles are fan-shaped; the valve plate, the top cover and the two side baffles form an exhaust port which opens downward and communicates with the exhaust hole.

[0010] Preferably, a shaft tube is fixed to the top of the blade, the connecting shaft passes through the shaft tube, and both ends of the connecting shaft are connected to the valve plate.

[0011] Preferably, a slot is provided at the bottom of the blade, and the slot matches the shaft tube; when two adjacent blades are put together, the slot is buckled with the shaft tube.

[0012] Preferably, the blade is bent to form a slot.

[0013] Preferably, a buffer strip is provided on the outer wall of the shaft tube; when two adjacent blades are put together, the inner wall of the slot is in contact with the buffer strip.

[0014] Preferably, the valve plate, the sunshade and the plurality of blades are made of aluminum alloy.

[0015] Preferably, an insect-proof net is provided on the valve plate, and the insect-proof net can cover the exhaust holes on the valve plate.

[0016] Preferably, a frame is protruded from one end of the valve plate, the blades are mounted in the frame, and the inner cavity of the frame is communicated with the exhaust hole of the valve plate.

[0017] Preferably, the edge of the valve plate is covered with a sealing member.

[0018] The beneficial effects of the technical solution of this utility model are as follows: Under normal circumstances, the blades of the positive pressure exhaust valve near the air outlet naturally droop due to gravity, isolating the indoor and outdoor air exchange. Only when the indoor air pressure is greater than the outdoor air pressure, the airflow blows the blades open and exhausts them to the outside, maintaining the indoor and outdoor pressure difference. However, when the indoor air pressure is less than the outdoor air pressure, the blades droop naturally, and the airflow cannot flow back into the room, preventing external pollutants from entering the mushroom house and affecting the growth of mycelium. At the same time, the positive pressure exhaust valve is equipped with a sunshade on the outside, which can effectively prevent ultraviolet rays and other light from entering the room, meeting the environmental requirements for mycelium growth in the room, preventing light from entering the mushroom house and inhibiting mycelium growth, and also protecting against the influence of wind, rain or other adverse weather conditions.

Example

[0031] like Figures 1 to 6 The positive pressure exhaust valve with sunshade for edible mushroom house shown includes a valve plate 1, a sunshade 4 and a plurality of blades 2;

[0032] The valve plate 1 is provided with an exhaust hole 12; a plurality of blades 2 are arranged up and down, with the top of the blade 2 being rotatably connected to the valve plate 1, and the bottom of the blade 2 being placed on the blade 2 or the valve plate 1 located below it; when two adjacent blades 2 are placed together, the plurality of blades 2 block the exhaust hole 12 of the valve plate 1; when two adjacent blades 2 are separated, the exhaust hole 12 of the valve plate 1 is opened;

[0033] The sun visor 4 includes a top cover portion 41 and two side stop portions 42. The top cover portion 41 is located between the two side stop portions 42, and the top cover portion 41 is fixedly connected to the side stop portions 42. The top cover portion 41 and the two side stop portions 42 are both fixedly connected to the valve plate 1. The position where the top cover portion 41 is connected to the valve plate 1 is above the exhaust hole 12, and the exhaust hole 12 is located between the two side stop portions 42.

[0034] With such an arrangement, under normal circumstances, the blades 2 of the positive pressure exhaust valve near the air outlet naturally droop due to gravity, isolating the air exchange between indoor and outdoor. Only when the indoor air pressure is greater than the outdoor air pressure, the air flow will blow the blades 2 open and exhaust them to the outside, ensuring the pressure difference between indoor and outdoor. However, when the indoor air pressure is lower than the outdoor air pressure, the blades 2 are in a self-drooping state, and the air flow cannot flow back into the room, preventing external pollutants from entering the mushroom room and affecting the growth of mycelium. At the same time, the positive pressure exhaust valve is provided with a sun visor 4 on the outside. The sun visor 4 can well prevent ultraviolet rays and other light from entering the room, meeting the environmental requirements for the growth of mycelium in the room, preventing light from entering the mushroom room and inhibiting the growth of mycelium, and can also resist the influence of wind, rain or other bad weather from the outside. In addition, there is no need for specialized personnel to operate and control, and the positive pressure valve can be opened and closed by relying on the indoor and outdoor wind pressure and the weight of the blades 2 themselves.

[0035] like Figure 1 As shown, in this embodiment, the top cover 41 is arc-shaped, and the side guards 42 are fan-shaped; the valve plate 1, the top cover 41, and the two side guards 42 form an exhaust port that opens downward and communicates with the exhaust hole 12. This arrangement can block light from all directions and improve the waterproof and dustproof properties of the positive pressure valve, so that it is not affected by adverse weather conditions.

[0036] like Figures 3 to 6 As shown, in this embodiment, a shaft tube is fixed on the top of the blade 2, and a connecting shaft 22 passes through the shaft tube. Both ends of the connecting shaft 22 are connected to the valve plate 1. In order to further improve the waterproof and dustproof performance of the positive pressure valve, as shown in FIG. Figure 4 and Figure 6 As shown, the bottom of the blade 2 is provided with a slot 21, which matches the shaft tube. When two adjacent blades 2 are placed together, the slot 21 engages the shaft tube. The blade 2 is bent to form the slot 21, and the connecting shaft 22 can be hinged or fixedly connected to the valve plate 1. This arrangement eliminates the need to worry about adverse conditions such as wind and rain when using the positive pressure valve. The external sunshade 4 can block rainwater, and the louvers rely on their own gravity to prevent rainwater from backflowing, providing dual protection.

[0037] Further preferably, a buffer strip is provided on the outer wall of the shaft tube; when two adjacent blades 2 are stacked together, the inner wall of the slot 21 contacts the buffer strip. The buffer strip comprises a rubber block. This arrangement reduces the noise generated by the blades 2 colliding with each other.

[0038] like Figure 1 As shown, in this embodiment, the valve plate 1 is provided with an insect screen 3 that covers the exhaust holes on the valve plate 1. The insect screen 3 and sunshades 4 are located on either side of the blades 2, with the insect screen 3 housed within the frame. This arrangement prevents insects and other small animals from entering the mushroom house, ensuring a stable environment within the house.

[0039] In this embodiment, the valve plate 1, sunshade 4, and multiple blades 2 are made of aluminum alloy. This configuration provides aluminum alloy with strong corrosion resistance, making it suitable for exhausting excess air from a mushroom room after humidification and disinfection. Aluminum alloy is also convenient, lightweight, durable, and has a small deformation range and a simple structure that is not easily deformed.

[0040] In this embodiment, a frame 11 protrudes from one end of the valve plate 1. The blades 2 and insect screen 3 are mounted within this frame 11. The interior of the frame 11 communicates with the exhaust holes 12 of the valve plate 1. The frame 11 and sunshade 4 are located on either side of the valve plate 1. This arrangement facilitates assembly of the positive pressure valve.

[0041] In this embodiment, the edge of the valve plate 1 is covered with a sealant. The sealant includes a rubber strip. This arrangement improves the installation effect of the positive pressure valve and the mushroom house.

[0042] The working principle of the positive pressure valve is as follows: Under normal circumstances, the blades 2 on the positive pressure exhaust valve naturally droop under the action of their own gravity, and the slots 21 between the two adjacent blades 2 are tightly locked with the shaft tube, thereby keeping the positive pressure valve in a closed state, isolating the air exchange between the indoor and outdoor areas of the mushroom house; because the growth of mushrooms produces carbon dioxide and other waste gases, and the humidity inside and outside the mushroom house is different, when the indoor air pressure is greater than the outdoor air pressure, the indoor air will push the blades 2, causing the two adjacent blades 2 to separate, thereby opening the positive pressure valve and discharging the indoor air to the outside.

[0043] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention without departing from the principles and purpose of the present invention.
