DETAILED DESCRIPTION
[0022] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0023] See also Figure 1 , embodiments of the present invention include:
[0024] A non-electric water heater comprises a hot water cylinder and a water isolation mechanism.
[0025] The hot water cylinder comprises a heat-insulating cylinder body 11 and a heat-insulating cylinder cover 12. The heat-insulating cylinder body 11 is cylindrical in shape, with an open top and a sealed bottom. Preferably, the heat-insulating cylinder body 11 has a stepped cylinder structure, with a larger top and a smaller bottom. The heat-insulating cylinder cover 12 is placed at the upper opening of the heat-insulating cylinder body 11, forming an internal enclosed space within the hot water cylinder. A water inlet pipe 13 communicating with the enclosed space is provided at the bottom of the heat-insulating cylinder body 11, and a water outlet pipe 15 communicating with the enclosed space is provided on the heat-insulating cylinder cover 12.
[0026] As shown in this embodiment, the heat-insulating cylinder 11 is a double-layer cylinder structure, including an inner cylinder 111 and an outer cylinder 112. The outer cylinder 112 is mounted on the outer side of the inner cylinder 111, and a gap is left between the outer cylinder 112 and the inner cylinder 111, and the gap is a vacuum space. The heat-insulating cylinder 11 is manufactured as follows: the inner cylinder 111 and the outer cylinder 112, the water inlet pipe 13 and the exhaust pipe 14 are welded together. The materials of the inner cylinder 111 and the outer cylinder 112 are both stainless steel plates, and the water inlet pipe 13 and the exhaust pipe 14 are both stainless steel round tubes. The water inlet pipe 13 is welded to the bottom of the inner cylinder 111, passes through the outer cylinder 112 and extends out of the cylinder, and is welded to the outer cylinder 112. The exhaust pipe 14 is welded to the outer cylinder 112. After the heat-insulating cylinder 11 is welded, it is sent to a high-temperature exhaust chamber to completely extract all the gas in the outer cylinder 112 and the inner cylinder 111, and then sealed. The top of the insulation cylinder 11 is externally threaded for securing it to the insulation cylinder cover 12. The insulation cylinder cover 12 is made of engineering plastic and features an insulating interlayer 121. A stainless steel water outlet is also installed on the cover. The insulating material is polyurethane, injected into the interlayer using a high-pressure foaming machine. The cover is internally threaded and has a sealing ring 122, threaded together with the cylinder.
[0027] The water-isolating mechanism is installed in the enclosed space of the hot water cylinder and includes a guide rod 21, a limit plate 22, and a water-isolating plate 23. The guide rod 21 is installed at the bottom of the heat-insulating cylinder 11, and the limit plate 22 is installed at the top of the guide rod 21. The water-isolating plate 23 is sleeved on the guide rod 21 and can move up and down along the guide rod 21. Preferably, the shape of the water-isolating plate 23 is the same as the shape of the bottom surface of the cylinder. A guide tube is provided in the middle of the water-isolating plate 23, and there is a certain gap between the water-isolating plate 23 and the inner wall of the cylinder. The top of the guide rod 21 is higher than the step where the small cross-sectional area of the heat-insulating cylinder 11 changes to a large cross-sectional area.
[0028] The non-electric water heater of the present invention is designed with a water path that combines water isolation and mixing, and adopts vacuum insulation technology, so that the water heater does not require an external power supply. Its basic structure is a cylindrical hot water cylinder with a larger upper part and a smaller lower part, which is assembled from two parts: a cylinder body and a cylinder cover. The outer shell of the cylinder body is a double-layer stainless steel structure, divided into an inner cylinder and an outer cylinder. The gap between the inner cylinder and the outer cylinder forms an excellent insulation layer by vacuuming. A hot water inlet pipe is provided at the bottom of the inner cylinder, which is connected to the hot water pipe on the wall under the washbasin cabinet that leads to the water heater. The cylinder cover is made of engineering plastic and has a PU insulation layer to ensure the thermal insulation performance of the cylinder cover. A hot water outlet is provided on the cylinder cover, which is connected to the hot water faucet inlet pipe of the washbasin under the cabinet.
[0029] Combine Figures 1 to 3As shown, the operating process of the non-electric water heater of the present invention is as follows: external water enters from the bottom of the inner cylinder, and internal water exits from the top of the cylinder cover. A circular, liftable water baffle is installed at the bottom of the inner cylinder, separating the internal water (the water stored in the inner cylinder) from the external water (the new water entering the inner cylinder). A retaining sleeve is installed in the middle of the water baffle. The baffle is attached to a guide rod in the middle of the inner cylinder through the retaining sleeve. The guide rod is equipped with a retaining plate, allowing the water baffle to move up and down between the retaining sleeve and the retaining plate on the guide rod. Normally, the water baffle is located at the bottom of the inner cylinder due to gravity. When external water enters, the baffle rises under the force of the water flow, and the hot water from the hot tap is the warmer internal water. If the water is drained for a long time, the baffle will enter the middle of the larger inner cylinder from the smaller diameter of the inner cylinder. At this time, the external water (which has risen in temperature) can enter the upper part of the inner cylinder through the larger gap around the baffle, mix with the internal water, and then be discharged from the hot tap. When the water stops flowing, the trap returns to the lower part of the inner cylinder under the influence of gravity, as the water flow ceases. When using the hot water dispenser for the first time, turn on the hot water tap. When the water reaches its maximum temperature, close the tap to allow the hot water tank to fill. When the tap is turned on again, the cooler outside water in the pipe first enters the inner cylinder. However, due to the barrier provided by the trap, this outside water does not mix directly with the inner water above. Instead, it pushes the trap upward, pushing the inner water out of the tap, and the water now released is hot. If the water continues to flow until the trap reaches the middle of the inner cylinder, the outside water enters the upper part of the inner cylinder through the gap around the trap, mixes with the inner water, and is released from the tap. At this point, the outside water has reached its maximum temperature and quickly fills the entire inner cylinder. During this period, the excellent vacuum insulation keeps the hot water in the inner cylinder at a high temperature, ensuring that you can always use it.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
