Description

Technical Field

[0001] This utility model relates to the field of flower planting technology, specifically a flower planting heat preservation device. Background Technology

[0002] Temperature is one of the key environmental factors affecting the growth and development of flowers during the cultivation process. Different types of flowers have specific temperature requirements for growth. For example, tropical flowers typically need a warm environment of 20℃-30℃ to grow well, while some cold-climate flowers, although having some cold tolerance, can still suffer frost damage under extreme low temperatures. In cold seasons or regions with large diurnal temperature variations, maintaining a suitable temperature environment is particularly important to ensure the normal growth of flowers. Therefore, heat preservation devices for flower cultivation are widely used in the flower cultivation industry.

[0003] Utility model patent CN220140322U discloses a flower planting insulation device. It utilizes biological lamps to raise the temperature of flowers inside the insulation cabinet, and injects fresh air into the cabinet via an air pump to provide an optimal environment for plant growth. The use of foam boards reduces heat loss during heating, resulting in better insulation. However, this patent has several problems in practical use. First, it only uses foam boards for insulation, employing a single insulation material, which leads to poor insulation performance. In low-temperature environments, heat is easily lost, making it difficult to maintain a suitable internal temperature for extended periods.

[0004] Secondly, the aforementioned patent uses biological lamps to heat the flowers inside the insulated cabinet. However, in actual use, this method is not convenient for flexibly adjusting the internal temperature of the insulated cabinet according to the temperature requirements of different growth stages of the flowers. Furthermore, biological lamps are generally fixed on the inner wall of the insulated cabinet, which cannot heat the inside of the insulated cabinet evenly. Therefore, it is necessary to design and modify the flower planting insulation device to effectively prevent the phenomenon of poor insulation effect. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a flower planting heat preservation device with the advantages of good heat preservation effect, maintaining a suitable internal temperature for a long time, and flexible adjustment of the internal temperature of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flower planting heat preservation device, comprising a heat preservation box, the heat preservation box including a storage cavity and a water cavity, the water cavity containing water, electric heating plates fixedly connected to both sides of the inner wall of the water cavity, a maintenance cover plate fixedly connected to the top of the heat preservation box by bolts, a sealing plate fixedly connected to the bottom of the maintenance cover plate, the bottom of the sealing plate being in contact with the top of the heat preservation box, a heat preservation layer fixedly connected to the surface of the heat preservation box and the surface of the maintenance cover plate, slide rails fixedly connected to both sides of the inner wall of the storage cavity, the number of slide rails being several, a bearing plate slidably connected inside the slide rails, an opening provided at the top of the bearing plate, the number of openings being several, the openings being evenly distributed at the top of the bearing plate, heat-conducting blocks fixedly connected to the inner wall of the water cavity, the number of heat-conducting blocks being several, and heat-conducting strips fixedly connected to the inner wall of the water cavity, the number of heat-conducting strips being several.

[0007] In a preferred embodiment of this invention, the insulation layer includes a first insulation layer fixedly connected to the surface of the insulation box and the top of the maintenance cover plate, a second insulation layer fixedly connected to the surface of the first insulation layer, and a third insulation layer fixedly connected to the surface of the second insulation layer.

[0008] As a preferred embodiment of this invention, an air pump is fixedly connected to the right side of the insulated box.

[0009] In a preferred embodiment of this invention, the slide rail is internally threaded with a threaded rod, the bottom of the threaded rod is fixedly connected to a pressure block, the bottom of the pressure block is in contact with the top of the bearing plate, and the top of the threaded rod is fixedly connected to a rotating handle.

[0010] As a preferred embodiment of this utility model, both sides of the front of the insulated box are hinged with insulated box doors, and the surfaces of the insulated box doors are respectively provided with observation windows and handles.

[0011] As a preferred embodiment of this utility model, the bottom of the insulated box is fixedly connected to support legs on all four sides, and the surfaces of the support legs are respectively fixedly connected to reinforcing frames and reinforcing rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a structural design that includes a storage chamber and a water chamber inside the insulated box. The water inside the water chamber is heated by an electric heating plate. Through the thermal conductivity of water, heat is evenly transferred to the left, right, top, bottom, and back of the storage chamber, thus avoiding the uneven local temperature problem caused by traditional single biological lamp heating to a certain extent. Several heat-conducting blocks and strips on the inner wall of the water chamber further enhance the heat transfer efficiency, allowing heat to diffuse more quickly and evenly throughout the entire storage chamber. The sealing plate at the bottom of the maintenance cover fits tightly against the top of the insulated box, effectively preventing heat loss from the gaps in the top of the box. This, combined with the insulation layer fixedly connected to the surface of the insulated box and the maintenance cover, further enhances the heat transfer efficiency. This multi-layered insulation structure significantly slows down the rate at which internal heat is transferred to the outside, maintaining a suitable temperature inside the storage chamber for extended periods even in cold environments. The design of the slide rails and support plates allows for flexible adjustment of the support plate position according to the planting needs of different flowers. Several openings at the top of the support plate promote air circulation within the storage chamber, ensuring that heated air can contact the flowers more evenly. This not only guarantees the flexibility of temperature regulation but also improves the overall insulation effect, effectively solving the problems of poor insulation performance and inflexible temperature regulation in existing devices. This device has the advantages of good insulation performance, maintaining a suitable internal temperature for a long time, and flexible adjustment of the internal temperature.

[0014] 2. This utility model employs a multi-layer composite structure with a first, second, and third insulation layer. The thermal conductivity and insulation properties of different insulation materials complement each other, synergistically blocking heat loss across different temperature ranges. The first insulation layer effectively blocks direct cold conduction from the external low-temperature environment to the insulation box. The second insulation layer reduces heat radiation loss through porous or reflective structures. The third insulation layer utilizes low thermal conductivity materials to slow down heat convection. This three-layer structure comprehensively suppresses heat loss from three dimensions: conduction, radiation, and convection. Compared to traditional single foam board insulation, its insulation performance is significantly improved. In cold seasons or environments with large diurnal temperature differences, this multi-layer insulation structure can significantly reduce temperature fluctuations within the storage cavity, effectively extending the maintenance time of a suitable internal temperature and reducing the frequent activation frequency of the electric heating plate. This ensures a stable growth environment for the flowers while saving energy consumption. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, a flower planting insulation device includes an insulation box 1, which includes a storage cavity 2 and a water cavity 3. The water cavity 3 is filled with water, and a drain valve (not shown) is connected to the bottom of the water cavity 3 for periodically draining the water. Electric heating plates 4 are fixedly connected to both sides of the inner wall of the water cavity 3. A maintenance cover plate 9 is fixedly connected to the top of the insulation box 1 by bolts. A sealing plate 10 is fixedly connected to the bottom of the maintenance cover plate 9, and the bottom of the sealing plate 10 is in contact with the top of the insulation box 1. An insulation layer 11 is fixedly connected to the surface of the insulation box 1 and the surface of the maintenance cover plate 9. Several slide rails 5 are fixedly connected to both sides of the inner wall of the storage cavity 2, and a bearing plate 6 is slidably connected inside the slide rail 5. The top of the support plate 6 has several openings, which are evenly distributed on the top of the support plate 6. The inner wall of the water cavity 3 is fixedly connected to several heat-conducting blocks 7. The inner wall of the water cavity 3 is fixedly connected to several heat-conducting strips 8. The inner wall of the storage cavity 2 is equipped with a temperature detector for detecting the temperature inside the storage cavity 2. The surface of the heat preservation box 1 is equipped with a controller for controlling the electrical appliances in the device. The temperature detector and controller are not shown. The heat-conducting blocks 7 and heat-conducting strips 8 are made of stainless steel. The temperature detector, controller and electric heating plate 4 are all existing common technologies and are common knowledge to those skilled in the art. This application will not describe them in detail.

[0023] refer to Figure 4The insulation layer 11 includes a first insulation layer 12 fixedly connected to the surface of the insulation box 1 and the top of the maintenance cover plate 9, a second insulation layer 13 fixedly connected to the surface of the first insulation layer 12, and a third insulation layer 14 fixedly connected to the surface of the second insulation layer 13.

[0024] As a technical optimization of this utility model, the insulation layer 11 adopts a multi-layer composite structure of a first insulation layer 12, a second insulation layer 13, and a third insulation layer 14. The thermal conductivity coefficients and thermal insulation properties of different insulation layer materials complement each other, and can synergistically block heat loss in different temperature ranges. The first insulation layer 12 can effectively block the direct cold conduction of the external low temperature environment to the insulation box 1, the second insulation layer 13 reduces heat radiation loss through a porous or reflective structure, and the third insulation layer 14 uses a low thermal conductivity material to slow down heat convection transfer. The three-layer structure addresses heat conduction and radiation... The insulation structure comprehensively suppresses heat loss in three dimensions: heat dissipation, heat transfer, and heat exchange. Compared with the traditional single foam board insulation method, its insulation performance is significantly improved. In cold seasons or environments with large temperature differences between day and night, this multi-layer insulation structure can greatly reduce the temperature fluctuation range in the storage cavity 2, effectively prolong the maintenance time of the suitable internal temperature, and reduce the frequent start-up frequency of the electric heating plate 4. This ensures a stable growth environment for flowers and saves energy consumption. The first insulation layer 12 can be made of aerogel, the second insulation layer 13 can be made of ceramic fiber felt, and the third insulation layer 14 can be made of glass wool.

[0025] refer to Figure 1 An air pump 15 is fixedly connected to the right side of the insulated box 1.

[0026] As a technical optimization of this utility model, the air pump 15, which is fixedly connected to the right side of the insulation box 1, can actively inject fresh air into the storage cavity 2, effectively improving the problem of poor air circulation caused by the closed environment of traditional insulation devices. The injection of fresh air provides sufficient carbon dioxide and oxygen for the photosynthesis and respiration of the flowers, promotes the metabolism of the flowers, and is conducive to their healthy growth. At the same time, the airflow generated by the air pump 15 when it is working can drive the air flow in the storage cavity 2. In conjunction with the design of the opening of the support plate 6, the heated air is more evenly distributed around the flowers, avoiding temperature deviation caused by air stagnation in local areas, and creating a better growth environment for the flowers. The working principle and usage of the air pump 15 in this device are the same as the air pump mentioned in the utility model patent disclosed in publication (announcement) number: CN220140322U, which is a flower planting insulation device. This application will not elaborate further.

[0027] refer to Figure 5 The slide rail 5 has an internal threaded connection to a threaded rod 19. A pressure block 20 is fixedly connected to the bottom of the threaded rod 19. The bottom of the pressure block 20 fits against the top of the bearing plate 6. A rotating handle is fixedly connected to the top of the threaded rod 19.

[0028] As a technical optimization of this utility model, the threaded rod 19 connected by the internal thread of the slide rail 5, in conjunction with the pressure block 20 at the bottom, allows for easy fixing or loosening of the bearing plate 6 by rotating the handle. When it is necessary to adjust the position of the bearing plate 6, simply rotate the handle to separate the pressure block 20 from the bearing plate 6, and then slide the bearing plate 6 along the slide rail 5 to the appropriate position. Then, rotate the handle in the opposite direction to press the pressure block 20 against the top of the bearing plate 6 to ensure its stable fixation. This structural design greatly improves the convenience of adjusting the position of the bearing plate 6.

[0029] refer to Figure 1 The insulated box 1 has doors 16 hinged to both sides of the front. The surface of the insulated box doors 16 is provided with observation windows 17 and handles.

[0030] As a technical optimization of this utility model, the observation window 17 allows direct observation of the growth status of the flowers inside the storage chamber 2 without opening the insulated box door 16, avoiding heat loss caused by frequent opening and closing of the box door and helping to maintain stable internal temperature. The observation window 17 is made of transparent heat-insulating material, ensuring visibility without significantly reducing the heat insulation performance of the insulated box door 16. The handle provides a convenient point of force for opening and closing the insulated box door 16, making operation easier and less strenuous. The sealing structure between the insulated box door 16 and the insulated box 1, combined with the sealing design of the maintenance cover plate 9, forms a comprehensive sealing system, effectively reducing heat loss from the gaps in the box door, further improving the heat insulation effect of the device, and providing a reliable environmental guarantee for the continuous and stable growth of the flowers.

[0031] refer to Figure 1 The bottom of the insulated box 1 is fixedly connected to four sides of the support legs 18, and the surface of the support legs 18 is fixedly connected to the reinforcing frame and the reinforcing rod respectively.

[0032] As a technical optimization of this utility model, the support legs 18 fixedly connected to the bottom of the insulated box 1 provide stable support for the device. The reinforcing frame and reinforcing rod fixedly connected to the surface of the support legs 18 significantly enhance the load-bearing capacity and deformation resistance of the support legs 18 through a triangular structure and cross support, which can effectively prevent the bottom deformation or tilting of the device due to its own weight or too many flowers placed in the storage cavity 2. The setting of the reinforcing frame and reinforcing rod also improves the overall rigidity of the support legs 18, making the device more stable when moving or subjected to external impact, reducing the risk of damage to the flowers inside due to shaking of the device. In addition, the height design of the support legs 18 keeps the bottom of the insulated box 1 at a certain distance from the ground, which is conducive to the air circulation at the bottom, reduces the erosion of the insulated box 1 by ground moisture, and extends the service life of the device, providing a more reliable guarantee for flower planting in terms of structural stability and durability.

[0033] The working principle and usage procedure of this utility model are as follows: When in use, connect the device to a stable power supply, turn on the air pump 15 switch on the right side of the insulation box 1, and observe whether the air pump 15 is operating normally and injecting fresh air into the storage cavity 2. The airflow should be evenly distributed around the opening of the support plate 6. Then check whether the temperature detector accurately senses the temperature inside the storage cavity 2. Set the target temperature through the controller on the surface of the insulation box 1. The controller will automatically adjust the working state of the electric heating plate 4 based on the temperature detector feedback. Next, install the support plate 6, sliding it from front to back into the slide rail 5 and fixing it in place. Then, place the potted flowers on top of the support plate 6.

[0034] When the electric heating plate 4 is turned on, the water in the water chamber 3 is heated by the electric heating plate 4, and the heat is evenly transferred to the storage chamber 2 through the heat-conducting block 7 and heat-conducting strip 8. At this time, the internal temperature rise can be observed through the observation window 17. When the temperature reaches the set value, the electric heating plate 4 will automatically stop working, using the heat storage characteristics of water to maintain a stable temperature. During the preheating process, the air pump 15 can be turned on to promote air circulation in the storage chamber 2, making the temperature distribution more uniform.

[0035] In daily management, the growth status of the flowers can be checked at any time through the observation window 17 without frequent opening of the box. Regularly check the surface of the insulation layer 11 for damage or stains, and clean or replace it in time if necessary to maintain good insulation performance.

[0036] Regarding temperature regulation, the controller can be flexibly set according to the needs of different growth stages of the flowers. For example, when tropical flowers require higher temperatures, the target temperature can be appropriately increased, and the controller will automatically extend the working time of the electric heating plate 4; for cold-climate flowers in low-temperature environments, the target temperature can be lowered, and the heat storage characteristics of the water chamber 3 can be used to maintain a suitable temperature. The air pump 15 can be turned on periodically, working for a period of time each time to provide fresh air for the flowers and promote photosynthesis and respiration.

[0037] During maintenance, regularly clean the inside of the water chamber 3 to prevent scale buildup from affecting heating efficiency. Turn off the power, open the maintenance cover 9, and wipe the surfaces of the electric heating plate 4 and heat-conducting block 7 with a soft cloth. Check if the connection between the threaded rod 19 and the slide rail 5 is loose; tighten it if necessary. The filter screen of the air pump 15 needs to be cleaned regularly to prevent dust blockage and reduced ventilation. After long-term use, if the insulation performance of the insulation layer 11 decreases, check if the insulation materials in each layer are aging and replace them if necessary.

[0038] In case of an emergency such as a power outage, the water in water chamber 3 can maintain its temperature for a period of time, and the air pump 15 and the chamber door can be temporarily shut off to reduce heat loss.
