Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The present application provides a pressure-bearing type solar water heater, comprising a water heater body 1 and a pretreatment mechanism 4:

[0027] The bottom of one side of the water heater body 1 is fixedly installed with a support 3, and the inner side wall of the support 3 is provided with a support mechanism 2 for installing and bearing the pretreatment mechanism 4, and the inside of the support mechanism 2 is provided with a pretreatment mechanism 4 for filtering cold water;

[0028] The support mechanism 2 comprises a containing assembly and an auxiliary assembly, the containing assembly is arranged on the inner side wall of the support 3, and the auxiliary assembly is arranged on the outer side of the containing assembly;

[0029] The containing assembly and the auxiliary assembly are beneficial to supporting and installing the pretreatment mechanism 4 and also can protect the pretreatment mechanism 4 inside.

[0030] The pre-treatment mechanism 4 comprises a placing assembly, a connecting assembly and a filtering assembly, the placing assembly is arranged in the inner part of the containing assembly, the connecting assembly is arranged in the inner part of the placing assembly, and the filtering assembly is arranged in the inner part of the placing assembly.

[0031] Through cooperation of the placing assembly, the connecting assembly and the filtering assembly, water can be filtered and adsorbed, so that less dirt is generated, and the water heater is protected.

[0032] Further,

[0033] As shown in Figure 3 , the containing assembly comprises a connecting cylinder 21, which is fixedly installed on the inner side wall of the support 3, and a sealing cover 22 is bolted on the top of the connecting cylinder 21, which plays a supporting and bearing role.

[0034] As shown in Figure 3 , the auxiliary assembly comprises a water inlet pipe 23, which is fixedly installed on the top of the sealing cover 22 in a penetrating manner, and a sealing ring 24 is sleeved on the outer side of the bottom of the sealing cover 22, which can realize auxiliary sealing and water inlet work.

[0035] First, cover the sealing cover 22 on the top of the connecting cylinder 21, then the sealing ring 24 will be precisely taken out of the inner side wall of the connecting cylinder 21, and finally locked and fixed through the flange and the bolt, and the water inlet pipe 23 is communicated with the pre-prepared pipeline to realize water inlet operation.

[0036] Preferably,

[0037] As shown in Figure 4 , the placing assembly comprises an inner ring 41, which is fixedly installed on the inner side wall of the connecting cylinder 21, and a filter cylinder 42 is bolted on the inner side of the inner ring 41, which is placed and taken out.

[0038] As shown in Figure 4 , the connecting assembly comprises a top cover 43, which is bolted on the top end of the filter cylinder 42, and a threaded ring 44 is fixedly installed on the top and bottom of the inner side wall of the filter cylinder 42, which is beneficial to realize the sealing cover operation.

[0039] As shown in Figure 4 , the filtering assembly comprises a filter 45 which is threadedly connected with the inner side wall of the threaded ring 44, and a rotating bar 46 is fixedly installed on the inner side wall of the filter 45, which realizes double-stage filtering operation.

[0040] During installation, first place the filter cylinder 42 on the inner ring 41, at this time the bottom end of the filter cylinder 42 will penetrate the inner ring 41 and be below it, then place the top cover 43 on the top of the filter cylinder 42, so as to realize the sealing operation, and the installation can be completed in time;

[0041] Then, install the sealing cover 22 according to the above installation method to achieve a seal. When the sealing cover 22 is installed, it will drive the water inlet pipe 23 downward, and the drain end of the water inlet pipe 23 will be directly inserted into the top of the inner cavity of the top cover 43 to facilitate subsequent water intake.

[0042] After the water is fed in, the water will flow directly into the interior of the filter cartridge 42 through the water inlet pipe 23. Then, the water will undergo dual-stage filtration through two sets of filters 45. The filtered water will then flow directly into the connecting cylinder 21 through the bottom of the filter cartridge 42, and then into the water heater body 1 through the water supply pipe 5 for heating.

[0043] in:

[0044] like Figure 2 As shown, one end of the water heater body 1 is connected to a water supply pipe 5, and the other end of the water heater body 1 is connected to a hot water drain pipe 6.

Then, the top cover 43 and the water inlet pipe 23 are removed. Subsequently, the filter cartridge 42 is released from its fixed state and directly removed from the inside of the connecting cylinder 21 to complete the initial disassembly operation. Then, the filter 45 is rotated by the rotating bar 46 to release the threaded connection between the filter 45 and the threaded ring 44, thereby completing the disassembly operation for subsequent replacement or cleaning.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
