DETAILED DESCRIPTION

[0040] The specific embodiments of the utility model are described in detail below in combination with the drawings, but it should be understood that the protection scope of the utility model is not limited by the specific embodiments.

[0041] Unless otherwise explicitly indicated, in the entire specification and claims, the term "comprises" or its variants such as "contains" or "includes" and the like will be understood to include the stated element or component, but not exclude other elements or components.

[0042] For the purposes of this description, spatially relative terms, such as "beneath", "below", "lower", "above", "upper", and the like, can be used to describe a relationship of one element or feature to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device is inverted or rotated by 90°, an element described as "below" or "beneath" another element or feature would then be oriented "above" or "over" the other element or feature. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90° or at other orientations) and the spatially relative terms used herein interpreted accordingly.

[0043] In this document, the terms "first", "second", etc. are used to distinguish between two different elements or portions, and are not used to define a particular position or relative relationship. In other words, in some embodiments, the terms "first", "second", etc. can also be interchanged with each other.

[0044] As shown in Figure 1 , 2 , the column structure of the solar shower column of the present application can integrate the solar heat collecting facility and the water storage into one, i.e. the surface of the column structure can use black heat absorbing material as the heat collecting facility, and the space inside the column is used as the water storage. Through the water path inside the column, the shower nozzle and the shower switch, an outdoor simple shower that can be easily disassembled and assembled can be formed, and hot water for showering can be obtained by using solar energy only. As further shown in Figure 1 , 2 , in order to facilitate disassembly and transportation, the solar shower column 100 of the present application includes a detachable upper column 101 and a lower column 102, which can be disassembled or locked and sealed by the upper column connecting cover 7 and the lower column connecting cover 12. The upper column 101 is provided with a shower nozzle 104 at the upper portion, and the lower column 102 is provided with a shower switch 105 (i.e. a cold and hot water mixing valve) at the upper portion, which is used to control the spraying of cold water, hot water or warm water by the shower nozzle 104.

The hot water pipe section B is connected to the 18L water valve shell 11 of the shower switch 105 at the upper end and is empty at the bottom of the lower column 102. After the hot water in the column is used, cold water is continuously supplied to the bottom of the column. Under the water pressure of the cold water, the water in the column is continuously heated during the upward process, so that the water reaching the top becomes hot water for the user to continue using. Figure 2 As shown in further 、

[0046] , the cold water flows in the cold water pipe sections in the direction of the green arrow, and the hot water flows in the column and outside the pipe sections in the direction of the red arrow.

[0049] Further as Figure 5 、 7-AAs shown in Figure 8-A, the outer edge open recess 10B of the lower column connecting cover 10 is located on the rotation starting side of the inner edge latch 81 of the knob, and the outer edge locking protrusion 10A is located on the rotation ending side of the inner edge latch 81 of the knob. The bottom of the starting end of the outer edge locking protrusion 10A has a locking slope 1011, which is used to form the upper column connecting cover and the lower column connecting cover to squeeze and wrap the intermediate sealing ring 7 when the inner edge latch 81 of the knob slides from the outer edge open recess 10B to the bottom of the outer edge locking protrusion 10A. Through the design of the locking slope 1011, the sliding of the inner edge latch 81 of the knob at the bottom of the outer edge locking protrusion 10A is smoother, and after reaching the top of the slope, it is just locked directly below the outer edge locking protrusion 10A.

[0050] Further as Figure 6-A As shown, one of the four knob inner edge latches 81 has a knob recess 82, correspondingly, as Figure 7-A As shown, a boss 10C is provided at a corresponding position below one of the four outer edge locking protrusions 10A; after the locking knob 8 is locked, the boss 10C is adapted to and connected with the knob recess 82 to form a stop for the locking knob 8 (that is, the boss 10C serves as the rotation termination position). With this arrangement, the inner edge latch 81 of the knob can only be aligned with the corresponding outer edge locking protrusion 10A before rotation and locking, effectively preventing installation errors by the installer. Further as... Figure 5 , 7-A As shown in Figure 9-B, the outer surface of the locking knob 8 of the upper column connecting cover has a knob protrusion 83; correspondingly, the outer surface of the lower column connecting cover 10 has a lower column connecting cover protrusion 10D; when the knob protrusion 83 and the lower column connecting cover protrusion 10D are aligned, it is the starting position for rotating the locking knob. In this way, the installer can better identify the required starting position for installation before locking. This utility model...

This pipe body water circuit sealing structure further includes an aluminum-plastic pipe clamp 3, an aluminum-plastic pipe sealing gasket 12, and a plastic locking nut 2. The aluminum-plastic pipe clamp 3 is fitted onto the outside of the aluminum-plastic pipe 1 and has a raised structure (i.e., a protrusion 3A), which corresponds to a groove 1A on the surface of the aluminum-plastic pipe 1 (see reference).Figure 11 )adapted. Aluminum plastic pipe sealing pad 12 is a stepped annular, stepped small circle inserted into the end of the aluminum plastic pipe 1 and placed in the upper side of the outer tooth direct joint (i.e. 20 turn 22 outer tooth direct 4) bottom. Plastic locking nut 2 is set on the outside of the aluminum plastic pipe clamp 3, when rotating the plastic locking nut 2 and forming a spiral feed with the upper side of the outer tooth of the outer tooth direct joint, it can drive the aluminum plastic pipe clamp 3 to move down until the protrusion 3A slides into the groove 1A, at this time the lower end of the aluminum plastic pipe 1 abuts on the annular surface of the stepped large circle of the aluminum plastic pipe sealing pad 12, forming the extrusion and sealing of the pipe body and the sealing pad.
