[0026] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] Please refer to the following: Figures 1 to 3 The present invention provides a heating device for edible mushroom greenhouses. The heating device includes a furnace body 1, an air supply pipe 3, and a connecting sleeve 4. An exhaust pipe 2 is installed on the furnace body 1; the air supply pipe 3 is fitted onto the outside of the exhaust pipe 2, and a blower 31 is connected to the bottom end of the air supply pipe 3; the connecting sleeve 4 is fitted onto the outside of the air supply pipe 3, and a connecting ring 41 is sealed to the bottom end of the connecting sleeve 4. The connecting ring 41 is fixedly installed on the outside of the air supply pipe 3 and is sealed to the air supply pipe 3. The connecting sleeve 4 and the air supply pipe 3 form a water supply trough.

[0028] The heating device for edible mushroom greenhouses provided in this embodiment, compared with the prior art, features a furnace body 1, an exhaust pipe 2 installed on the furnace body 1, and an air supply pipe 3 fitted outside the exhaust pipe 2. An air supply box is connected to the bottom of the air supply pipe 3, and the air supply box is sealed to the outer wall of the exhaust pipe 2. A blower 31 is installed on the air supply box to supply air into the air supply box. The air is heated inside the air supply pipe 3 and then discharged to heat the greenhouse. In this application, a connecting sleeve 4 is fitted outside the air supply pipe 3, and a connecting ring 41 at the bottom of the connecting sleeve 4 forms a water supply tank that is sealed to the air supply pipe 3. During use, liquid can be added to the water supply tank. During operation, the air supply pipe 3 transfers heat to the liquid, raising the liquid temperature and generating water vapor that disperses into the greenhouse, alleviating dryness and stabilizing humidity within the greenhouse. This provides a stable growing environment for edible mushrooms.

[0029] Specifically, in this embodiment, a connecting ring 41 is welded to the bottom of the connecting sleeve 4. The connecting ring 41 can be welded to the outside of the air supply pipe 3. The air inside the air supply pipe 3 is heated by the exhaust pipe 2 and then transferred to the liquid inside the water supply tank, causing the liquid to heat up and generate water vapor, thereby increasing the humidity of the external environment. The output end of the exhaust pipe 2 extends to the outside of the greenhouse to discharge the exhaust gas generated by the combustion of the furnace 1 to the outside of the greenhouse.

[0030] In some embodiments, the aforementioned air supply duct 3 can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 Multiple heat dissipation fins 5 are fixedly installed on the side wall of the air supply duct 3. The heat dissipation fins 5 are spaced apart from the inner wall of the connecting sleeve 4. The multiple heat dissipation fins 5 are evenly spaced along the circumference of the air supply duct 3 and located inside the water supply tank. Multiple heat dissipation fins 5 are arranged on the outer wall of the air supply duct 3 and are located inside the water supply tank. Both the air supply duct 3 and the heat dissipation fins 5 are made of metal. When the temperature of the air supply duct 3 rises, it will be conducted to the liquid through the heat dissipation fins 5. At the same time, the increase in the number of heat dissipation fins 5 will also increase the heating area of ​​the liquid inside the water supply tank, which can raise the temperature of the liquid inside the water supply tank more quickly and increase the heating rate of the liquid.

[0031] Specifically, in this embodiment, there is a gap between the heat dissipation fins 5 and the inner wall of the connecting sleeve 4, so as to ensure that the liquid inside the water supply tank is in a state of mutual communication.

[0032] In some embodiments, the water supply tank described above may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3The top of the water supply tank is covered with a cover plate 6, which overlaps the top of the heat dissipation fins 5 and the connecting sleeve 4. Multiple exhaust slots are spaced along the circumference of the cover plate 6. The cover plate 6, with its evenly distributed exhaust slots, prevents external impurities from entering the water supply tank. Simultaneously, the evenly distributed exhaust slots on the cover plate 6 ensure that the generated steam is evenly distributed around the periphery of the air supply pipe 3.

[0033] In some embodiments, the water supply tank described above may be as follows: Figure 2 The structure shown. See also Figure 2 The cover plate 6 comprises two semi-circular arc-shaped plates, which are joined together to form the cover plate 6. The cover plate 6 is composed of two semi-circular arc-shaped plates, which allows the two arc-shaped plates to be detached from the top of the connecting sleeve 4 when adding liquid into the water supply tank, making it convenient to add liquid.

[0034] In some embodiments, the cover plate 6 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The top of the connecting sleeve 4 is provided with a mounting groove for accommodating the cover plate 6. The cover plate 6 includes an outer arc plate 61, an inner arc plate 62, and a connecting plate 63. The outer arc plate 61 slides in fit with the inner wall of the mounting groove; the inner arc plate 62 slides in fit with the air supply pipe 3, and the inner diameter of the inner arc plate 62 gradually decreases from top to bottom; the connecting plate 63 connects the top of the outer arc plate 61 and the inner arc plate 62. A flange is fixedly installed on the top of the connecting sleeve 4, and a mounting groove for installing the cover plate 6 is recessed on the flange. The outer arc plate 61 of the cover plate 6 overlaps the bottom of the mounting groove and slides in fit with the inner wall of the mounting groove. When the cover plate 6 is installed on the top of the connecting sleeve 4, the outer arc plate 61 is located inside the mounting groove, and the bottom end of the inner arc plate 62 abuts against the heat dissipation fins 5. When water droplets condense on the cover plate 6, the water droplets can slide down onto the air supply pipe 3 through the inclined guide of the inner arc plate 62. When the side wall temperature of the air supply pipe 3 is too high, the water droplets can be reheated and evaporated, and the excess water droplets can fall back into the water supply tank.

[0035] Preferably, in this embodiment, there is a gap between the bottom end of the inner arc plate 62 and the outer wall of the air supply pipe 3, which can collect the water droplets condensed on the outside and collect them into the water supply tank.

[0036] In some embodiments, the cover plate 6 may be adopted as follows: Figure 3 The structure shown. See also Figure 3Both the outer arc plate 61 and the connecting plate 63 are provided with venting grooves, and the inner arc plate 62 is provided with a water trough for adding liquid into the water trough. The venting groove on the outer arc plate 61 can guide the generated steam to be discharged radially along the connecting sleeve 4, while the venting groove on the connecting plate 63 can guide the generated steam to be discharged upward, so that the generated steam can be evenly distributed to the outside, ensuring uniform distribution of water vapor.

[0037] Specifically, in this embodiment, a water flow channel is provided on the inner arc plate 62. The inner diameter of the inner arc plate 62 gradually increases from bottom to top, thereby forming a conical groove between the inner arc plate 62 and the air supply pipe 3. When adding liquid, the liquid can be added into the conical groove and flow into the water supply tank through the water flow channel on the inner arc plate 62. Liquid can be added into the water supply tank without removing the cover plate 6. The inclined arrangement of the inner arc plate 62 can both guide condensed water droplets and form a conical groove with the air supply pipe 3 to facilitate the addition of liquid.

[0038] In some embodiments, the outer arc plate 61 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 The bottom of the outer arc plate 61 is also bent to form a support ring 64 for abutting against the bottom of the mounting groove. The inner diameter of the support ring 64 gradually decreases from top to bottom. When the outer arc plate 61 is installed into the mounting groove, the bottom end of the support ring 64 is flush with the inner hole of the connecting sleeve 4. The outer wall of the support ring 64 guides the outer arc plate 61 into the mounting groove, while the inner wall guides condensed water droplets back into the water supply tank. Simultaneously, the support ring 64 and the inner arc plate 62 are inclined in the same direction, guiding the generated steam away from the air supply pipe 3.

[0039] In some embodiments, the exhaust pipe 2 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 Multiple heat transfer fins 51 are installed between the exhaust pipe 2 and the air supply pipe 3. These fins are evenly spaced along the circumference of the exhaust pipe 2 on its outer side, and their height is the same as that of the heat dissipation fins 5. The two sides of the heat transfer fins 51 are welded and fixed between the exhaust pipe 2 and the air supply pipe 3. The exhaust pipe 2 is directly affected by combustion inside the furnace 1, resulting in a high temperature. The heat transfer fins 51 effectively and quickly transfer heat from the exhaust pipe 2 to the air supply pipe 3, allowing the air supply pipe 3 to fully absorb heat and increase its temperature, thus accelerating the heating of the liquid inside the water supply tank. Simultaneously, the liquid inside the water supply tank can reach boiling point, generating a large amount of steam that is transferred into the greenhouse, increasing the humidity inside.

[0040] Specifically, in this embodiment, the heat transfer fins 51 can also increase the temperature of the air between the air supply pipe 3 and the exhaust pipe 2, thereby raising the temperature of the air transported inside the air supply pipe 3 and ensuring an effective heating effect.

[0041] In some embodiments, the heat dissipation fins 5 and the heat transfer fins 51 described above can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The heat dissipation fins 5 and heat transfer fins 51 are integrated into a single structure. Both fins are integrally formed from a steel plate, which is then passed through the air supply duct 3 and pressed against the exhaust duct 2. The steel plate is then welded to both the exhaust duct 2 and the air supply duct 3. This integrated structure allows for direct heat transfer from the exhaust duct 2 to the liquid in the water supply tank, enabling the liquid to reach boiling point more quickly.

[0042] Specifically, in this embodiment, multiple sets of heat dissipation fins 5 and heat transfer fins 51 are provided on the air supply duct 3, and the multiple sets of heat dissipation fins 5 and heat transfer fins 51 are arranged sequentially at intervals along the length of the air supply duct 3.

[0043] In some embodiments, the above-mentioned three air supply ducts can be adopted as follows: Figure 1 The structure shown. See also Figure 1 A dust cover 7 is fixedly installed on the top of the air supply duct 3. The inner diameter of the dust cover 7 gradually increases from top to bottom, and the connecting sleeve 4 is located below the dust cover 7. The dust cover 7 is fitted onto the outside of the exhaust duct 2 and is located on top of the air supply duct 3. When gas is discharged from inside the air supply duct 3, the gas moves downward through the refraction of the dust cover 7 and merges with the steam output from the water supply tank. The gas then carries the steam to disperse into the surrounding air, achieving the effect of humidifying the surrounding air.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
