Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flower transportation, and particularly relates to a flower transportation and heat preservation device. Background Art
[0002] Peonies are relatively delicate. When transported over long distances, especially to cold regions such as the Northeast and Northwest in winter, the flowers can easily be frozen or even killed due to the low temperature. Our company's patent, application number 2022218649308, announcement date 2023.03.17, and titled "A self-heating control device for flower transportation", controls the entry of air to complete the oxidation reaction and release heat to keep the flowers warm during transportation. However, flowers are generally sealed during transportation, and the amount of air entering is not sufficient. Furthermore, the oxidation reaction releases heat slowly, which cannot provide sufficient insulation effect for flowers in cold weather. Finally, it requires a variety of materials to make heating bags, which greatly increases transportation costs. Utility Model Content
[0003] In order to make up for the deficiencies of the prior art, the utility model provides a flower transportation and heat preservation device with fast heat release speed, low cost and good heat preservation effect.
[0004] The utility model is realized through the following technical solutions:
[0005] A flower transport and heat preservation device comprises an upper tube and a lower tube connected together, and is characterized in that a cover plate is arranged between the lower tube and the upper tube, a mounting frame is arranged above the cover plate, a valve stem is passed through the mounting frame, a thermal spring located inside the mounting frame and a constant force spring located outside the mounting frame are sleeved on the valve stem, and a water outlet hole opposite to the valve stem is opened on the cover plate.
[0006] The bottom of the valve stem is integrally connected with a probe extending into the water outlet.
[0007] A guide plate is installed at the lower part of the valve stem.
[0008] The top of the valve stem is integrally connected with an elastic hook.
[0009] The outer periphery of the cover plate is integrally provided with a connecting plate, the lower part of the connecting plate is connected to the lower cylinder through a thread, and the upper part of the connecting plate is connected to the upper cylinder through a thread.
[0010] A waterproof and breathable membrane is arranged on the top of the upper cylinder.
[0011] The side wall of the lower cylinder is provided with an air outlet.
[0012] The beneficial effect of the utility model is that when the temperature in the packaging box for transporting flowers is low, the thermal spring retracts to drive the probe upward, so that the water outlet connects the water in the upper tube and the lower tube, so that the water will flow into the lime bag in the lower tube, release heat, and thus keep the flowers warm. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The utility model is further described below in conjunction with the accompanying drawings.
[0014] Attached Figure 1 It is a schematic diagram of the structure of the utility model;
[0015] In the figure, 1 is an upper cylinder, 2 is a lower cylinder, 3 is a cover plate, 4 is a mounting frame, 5 is a valve stem, 6 is a thermal spring, 7 is a constant force spring, 8 is a water outlet, 9 is a probe, 10 is a guide plate, 11 is an elastic hook, 12 is a connecting plate, 13 is a waterproof breathable membrane, and 14 is an air outlet. DETAILED DESCRIPTION
[0016] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes an upper tube 1 and a lower tube 2 connected together, a cover plate 3 is provided between the lower tube 2 and the upper tube 1, a mounting frame 4 is provided above the cover plate 3, a valve stem 5 is inserted in the mounting frame 4, a thermal spring 6 located on the inner side of the mounting frame 4 and a constant force spring 7 located on the outer side of the mounting frame 4 are sleeved on the valve stem 5, and a water outlet 8 opposite to the valve stem 5 is provided on the cover plate 3. A probe 9 extending into the water outlet 8 is integrally connected to the bottom of the valve stem 5. A guide plate 10 is installed at the lower part of the valve stem 5. An elastic hook 11 is integrally connected to the top of the valve stem 5. A connecting plate 12 is integrally provided on the outer periphery of the cover plate 3, the lower part of the connecting plate 12 is connected to the lower tube 2 by a thread, and the upper part of the connecting plate 12 is connected to the upper tube 1 by a thread. A waterproof and breathable membrane 13 is provided on the top of the upper tube 1. An air outlet 14 is provided on the side wall of the lower tube 2.
[0017] The flower transport and heat preservation device of the utility model is adopted. A lime bag is placed in the lower tube 2, water is added to the upper tube 1, the cover plate 3 is screwed on the upper tube 1 through the connecting plate 12, and then the upper tube 1 is inverted, and the cover plate 3 is screwed on the lower tube 2 through the connecting plate 12. The device is placed in a packaging box together with flowers for transportation. When the temperature is low, the thermosensitive spring 6 retracts, and under the action of the constant force spring 7, the valve stem 5 is lifted upward, thereby driving the probe 9 to be lifted upward. At this time, the water in the upper tube 1 will flow into the lime bag of the lower tube 2 through the water outlet 8. The lime reacts with water, and heat is released during the reaction process, thereby increasing the temperature in the packaging box, and then the flowers are kept warm. When the temperature reaches a certain level, the thermosensitive spring 6 will extend again, push the valve stem 5 to fall, and then drive the probe 9 to fall. The probe 9 extends into the water outlet 8 to block the water outlet 8, so that the water in the upper tube 1 can no longer flow into the lower tube 2. This cycle is repeated to complete the heat preservation of flowers during transportation. The guide plate 10 ensures that the valve stem 5 always moves along the same straight line when it moves up and down multiple times, thereby ensuring the linearity of the movement of the probe 9 and further ensuring the sealing effect. When lime reacts with water, it releases gas. When the gas pressure is too high, the gas will flow out of the lower tube 2 from the air outlet 14 to ensure the safety of the device. When the water in the upper tube 1 flows out, a vacuum is formed above the upper tube 1, and the waterproof and breathable membrane 13 allows air to enter the upper tube 1, ensuring that water will flow smoothly into the lower tube 2.
