Problems solved by technology

[0003] When people use solar water heaters for bathing, there is often such a problem: when the water is released, because the water cooled down during the last bath remains in the water pipe, it is necessary to put cold water for a period of time before bathing each time, which not only causes Water resources are wasted. At the same time, people need to wait for a period of time when taking a bath. In the cold winter, it is easy to catch a cold.

Embodiment 1

[0020] refer to Figure 1-2 , a water-saving device for solar water heaters, comprising a base 1, the side wall of the base 1 is provided with a bar-shaped groove 2, the upper end of the base 1 is fixedly connected with a water inlet pipe 3 communicating with the inside of the bar-shaped groove 2, and the bar-shaped A sliding plug 4 is sealed and slidably connected in the groove 2, and the upper end of the sliding plug 4 is elastically connected to the inner top of the bar-shaped groove 2 through a memory alloy spring 5 .

[0021] It should be noted that the memory alloy spring 5 is made of a titanium-nickel alloy material, which is in a contracted state at room temperature and in an extended state at about 40 degrees. Moreover, the stiffness coefficient of the memory alloy spring 5 is relatively large, and elastic deformation will not occur under the impact of the water flow of the water inlet pipe 3 .

[0022] The side wall of the sliding plug 4 is fixedly connected with an...

Embodiment 2

[0028] refer to Figure 3-4 The difference from the first embodiment is that the sliding plug 4 is made of magnetic material, and the water storage chamber 7 is sealed and slidably connected with an iron slider 9, and the inner wall of the water storage chamber 7 is fixedly connected with a plurality of limit blocks. 10. The lower end of the sliding plug 4 is fixedly connected with the lower baffle 11 , and the side wall of the lower baffle 11 is in close contact with the inner wall of the strip groove 2 .

[0029] It should be noted that by arranging a plurality of limit blocks 10, the slider 9 can be blocked when the magnetic slider 4 attracts the iron slider 9 to move down, so as to prevent the slider 9 from pressing down on the water outlet pipe 8 and causing the water outlet pipe to 8 damaged. And the outer wall of slide block 9 is coated with antirust coating.

[0030] Further, the volume of the water storage chamber 7 and the cross-sectional area of ​​the slider 9 are...

Abstract

The invention discloses a water saving device for a solar water heater. The water saving device comprises a pedestal, wherein a strip-shaped slot is formed in the side wall of the pedestal; the upperend of the pedestal is fixedly connected to a water inlet tube which communicates with the inner part of the strip-shaped slot; a slide plug is in sealing sliding connection in the strip-shaped slot;the upper end of the slide plug is elastically connected to the inner top of the strip-shaped slot through a memory alloy spring; the side wall of the slide plug is fixedly connected to an upper baffle plate; a through hole is formed in the side wall of the upper baffle plate; a water storage cavity is arranged on the side wall of the pedestal; and the water storage cavity communicates with the strip-shaped slot through a water guide hole. According to the water saving device disclosed by the invention, while the water inlet tube is placed into cold water with a low temperature, the memory alloy spring is in a shrinkage rate while the through hole communicates with the water guide hole for directly flowing cold water into the water storage cavity for storage, so that water resource waste is avoided; and cold water in the water storage cavity is extruded into the water outlet tube and is mixed with hot water, so that cold water also can be recycled, and therefore, bath water can be saved.

Description

technical field [0001] The invention relates to the technical field of bathing equipment, in particular to a water-saving device for a solar water heater. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. [0003] When people use solar water heaters for bathing, there is often such a problem: when the water is released, because the water cooled down during the last bath remains in the water pipe, it is necessary to put cold water for a period of time before bathing each time, which not only causes Water resources are wasted, and people also need to wait for a period of time when taking a bath, and it is easy to catch a cold in the cold winter. Contents of the invention [0004] The object of the present invention is to propose a water-saving device for solar water heaters in order to...
