Description

Technical Field

[0001] The utility model relates to the technical field of solar water heaters, in particular to a solar water heater with an electric heating auxiliary water tank. Background Technique

[0002] A solar water heater is a device that uses the sun to heat water temperature. Generally, a solar water heater is a vacuum tube type solar water heater. A household vacuum tube solar water heater is composed of a heat collecting tube, a water storage tank, brackets and other related parts. Converting solar energy into heat energy mainly relies on the vacuum heat collecting tube. Using the principle that hot water floats and cold water sinks, water is made to produce microcirculation to reach the required hot water.

[0003] Currently, most electric heating auxiliary water tanks are mostly welded to the surface of the solar water heater, so that the electric heating auxiliary water tank can be installed on the top of the solar water heater; however, due to the long-term use of the electric heating auxiliary water tank outdoors, the rainwater outdoors will cause corrosion to the electric heating auxiliary water tank, and the direct welding of the electric heating auxiliary water tank to the surface of the solar water heater may make maintenance or replacement very difficult, and even require the disassembly of the entire water heater, increasing the maintenance cost and time, and may even cause damage to the electric heating auxiliary water tank, making the electric heating auxiliary water tank unable to continue to be used, and thus being inconvenient to use. In view of this, we introduce a solar water heater with an electric heating auxiliary water tank. Content of the Utility Model

[0004] The purpose of the utility model is to provide a solar water heater with an electric heating auxiliary water tank to solve the problems raised in the above background technique.

A connecting pipe is arranged on the surface of the auxiliary water tank and below the water inlet pipe, and the connecting pipe is connected to the inside of the solar water heater. Then the water source inside the auxiliary water tank can enter the inside of the solar water heater through the connecting pipe;

[0009] A fixing mechanism is arranged inside the fixing frame. The gear of the fixing mechanism drives the toothed plate and the inserting rod to move, so that the inserting rod penetrates through the supporting block to fix the auxiliary water tank.

[0010] Preferably, the fixing mechanism includes a positioning cavity arranged inside the fixing frame. The positioning cavity and the fixing frame are integrally formed. A gear groove is formed inside the fixing frame and below the positioning cavity. The gear groove and the fixing frame are integrally formed. The gear is connected inside the gear groove.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] (1). By reversing the driving block, the rotation of the driving block drives the rotating rod and the gear to rotate. Since the gear meshes with the toothed plate, the gear can drive the toothed plate to move inside the positioning cavity.
