Description

Technical Field

[0001] This utility model relates to the field of shower equipment technology, and in particular to a water channel sealing structure and a solar shower column using the structure. Background Technology

[0002] A solar shower column absorbs solar energy and converts it into heat through a solar collector, typically a heat-absorbing material that heats the cold water inside. The heated water is then mixed with cold water from external pipes for use in outdoor environments, such as beach showers. Generally, the solar collector absorbs solar energy and converts it into heat, while the water tank stores the heated water. A solar shower column integrates both the solar collector and the water tank into one unit. The column's surface can be made of black heat-absorbing material, while the interior serves as the water tank. By connecting the water channels, shower heads, and shower controls within the column, a simple, easily assembled and disassembled outdoor shower can be created, providing hot water solely through solar energy.

[0003] Chinese patent application CN201098053Y discloses a detachable solar water heater that provides hot, warm, and cold water to a shower unit heated by solar radiation. It includes upper and lower outer pipes, double-layered end caps sealing both ends, a supporting base, a connector assembly on the pipe wall for sealing connection to the water source, an inlet pipe, an outlet pipe, and a cold water pipe inside the pipes, each connected to a three-way valve body with an operating handle, a tee at the top of the cold water pipe, and a shower head. The upper and lower outer pipes and the cold water pipe are connected to the three-way valve body via an upper inner plug, a lower inner plug, a locking ring, a pipe connector, an inner connector, and a middle connector, forming a structure that allows for easy disassembly, separation, or reassembly to form a sealed connection. This reduces packaging, storage, and transportation dimensions, and facilitates disassembly, maintenance, or parts replacement, making it suitable for installation and use in places such as seaside resorts and outdoor swimming pools.

[0004] The water channel sealing structure of this type of solution, especially the column water channel sealing, generally adopts threaded connection, which is inconvenient to disassemble and assemble, and the sealing effect cannot be effectively guaranteed.

[0005] Therefore, there is an urgent need for a waterway sealing structure that can be easily disassembled and assembled while ensuring sealing performance, as well as a solar shower column that uses this structure.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a water channel sealing structure and a solar shower column using this structure, which can be easily disassembled and assembled while ensuring sealing performance.

[0008] To achieve the above objectives, according to a first aspect of this utility model, a water channel sealing structure is provided for use in a solar shower column, comprising at least a column body water channel sealing structure, which further comprises: an upper column connecting cover, which is sleeved on the lower end of the upper column of the solar shower column, and has four arc-shaped slots extending circumferentially and evenly spaced inside the upper column connecting cover, the arc-shaped slots having an open portion and a locking portion; and a lower column connecting cover, which is sleeved on the upper end of the lower column of the solar shower column, the lower column connecting cover having four arc-shaped slots extending circumferentially and evenly spaced inside the lower column connecting cover. Four evenly spaced arc-shaped buckles are provided, with their dimensions matching the open and locking portions of the arc-shaped slots. During the rotation of the upper column connecting cover relative to the lower column connecting cover, the arc-shaped buckles can slide from the open portion to the locking portion, forming a lock between the upper and lower column connecting covers. An intermediate sealing ring is located in a sealing ring placement groove within the lower column connecting cover. When the upper and lower column connecting covers are locked, the intermediate sealing ring is bidirectionally compressed and wrapped by the upper and lower column connecting covers, forming a water channel seal in the column body after the upper and lower columns are connected.

[0009] Furthermore, in the above technical solution, the open part is located on the rotation start side of the arc-shaped groove, and the locking part is located on the rotation end side of the arc-shaped groove; the locking part has an outer locking slope and an inner locking slope, which are used to form the upper column connecting cover and the lower column connecting cover to squeeze and wrap the middle sealing ring when the arc-shaped buckle slides from the open part to the locking part.

[0010] Furthermore, in the above technical solution, one of the four arc-shaped slots may be provided with a slot protrusion, and correspondingly, one of the four arc-shaped buckles may be provided with a buckle recess.

[0011] Furthermore, in the above technical solution, the outer edge surface of the upper column connecting cover may be provided with an upper column connecting cover embossed pattern; the outer edge surface of the lower column connecting cover may be provided with a lower column connecting cover recessed pattern and a lower column connecting cover embossed pattern; when the upper column connecting cover embossed pattern and the lower column connecting cover recessed pattern are aligned, it is the starting position for rotation of the upper column connecting cover; when the upper column connecting cover is rotated clockwise and the upper column connecting cover embossed pattern is aligned with the lower column connecting cover embossed pattern, it is the locking termination position for the upper column connecting cover and the lower column connecting cover.

[0012] Furthermore, in the above technical solution, the water circuit sealing structure may also include a pipe body water circuit sealing structure, used to connect the pipe body to the internal and external thread direct connector while forming a pipe body water circuit seal; the pipe body is preferably made of aluminum-plastic pipe, which is the cold water pipe installed inside the solar shower column; the pipe body water circuit sealing structure further includes: an aluminum-plastic pipe clamp, which is sleeved on the outside of the pipe body and has a raised structure, which is adapted to the groove at the corresponding position on the surface of the pipe body; an aluminum-plastic pipe sealing gasket, which is in the shape of a stepped annulus, with the small stepped circle inserted into the end of the pipe body and placed as a whole at the bottom of the external thread side inside the internal and external thread direct connector; a plastic locking nut, which is sleeved on the outside of the aluminum-plastic pipe clamp, and when the plastic locking nut is rotated and forms a spiral feed with the external thread of the internal and external thread direct connector, it can drive the aluminum-plastic pipe clamp to move down until the raised structure slides into the groove. At this time, the end of the pipe body abuts against the annular surface of the large stepped circle of the aluminum-plastic pipe sealing gasket, forming a compression and sealing between the pipe body and the sealing gasket.

[0013] Furthermore, in the above technical solution, the internal thread of the direct connector is connected to the guide connector on the water valve housing. The two ends of the guide connector on the water valve housing are preferably off-axis, so that the water passage at the junction is axially offset, avoiding obstruction during component installation.

[0014] According to a second aspect of the present invention, the present invention provides a solar shower column, comprising a detachably connected upper column and a lower column, and applying the aforementioned water channel sealing structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) This utility model uses a snap-fit ​​and slot connection structure to replace the threaded connection in the prior art through the internal structure of the upper column connecting cover and the lower column connecting cover. Not only is the structure compact and does not take up too much space, but after the upper column connecting cover and the lower column connecting cover are connected and locked, they can form a bidirectional compression and wrapping of the middle sealing ring, making the connection stable and improving the water channel sealing effect of the column.

[0017] 2) In the mating structure of the upper column connecting cover and the lower column connecting cover of this utility model, the locking part of the arc-shaped groove adopts a double slope design of the outer locking slope and the inner locking slope, which makes the arc-shaped buckle slide more smoothly in the arc-shaped groove, and can be just locked on the rotation termination side of the arc-shaped groove after reaching the top of the slope.

[0018] 3) One of the four arc-shaped slots in this utility model has a slot protrusion, and correspondingly, one of the four arc-shaped buckles has a buckle recess. This design ensures that only the corresponding buckle and slot can be matched and inserted, effectively preventing installation errors by the installer.

[0019] 4) This utility model uses the upper column connecting cover convex print on the outer edge surface of the upper column connecting cover and the lower column connecting cover concave print and lower column connecting cover convex print on the outer edge surface of the lower column connecting cover to make it easier for installers to identify the locking and unlocking status.

[0020] 5) This utility model, through the cooperation of components such as aluminum-plastic pipe, plastic locking nut, aluminum-plastic pipe clamp, internal and external thread direct connector and aluminum-plastic pipe sealing gasket, can form the compression and sealing of the pipe body and the sealing gasket, which is convenient to install and has better sealing performance.

[0021] 6) The two ends of the guide joint on the water valve housing of this utility model are set off-axis, so that the water passage at the transition point is axially offset. This setting can effectively avoid the problem of obstructing the installation of components.

[0022] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, and to make the above and other objects, technical features and advantages of this utility model easier to understand, one or more preferred embodiments are listed below and described in detail with reference to the accompanying drawings.

Detailed Implementation

[0041] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0042] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0043] In this document, for ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” “upper,” etc., are used to describe the relationship of one element or feature to another element or feature in the accompanying drawings. It should be understood that spatial relative terms are intended to encompass different orientations of an object in use or operation, in addition to those depicted in the figures. For example, if an object in the figure is flipped, an element described as “below” or “under” another element or feature would be oriented “above” that element or feature. Thus, the exemplary term “below” can encompass both the downward and upward orientations. An object may also have other orientations (rotated 90 degrees or other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0044] In this document, the terms "first," "second," etc., are used to distinguish two different elements or parts, and are not used to define specific positions or relative relationships. In other words, in some embodiments, the terms "first," "second," etc., can also be used interchangeably.

[0045] like Figures 1 to 5 As shown, the column structure of this utility model integrates the solar thermal collector and the water storage unit into one piece. Specifically, the surface of the column structure can be made of black heat-absorbing material as the heat collector, while the internal space of the column serves as the water storage unit. By connecting the water channels, shower head, and shower switch within the column, a simple, easily detachable outdoor shower can be formed, utilizing only solar energy to obtain hot water for showering. Further... Figures 1 to 5 As shown, for ease of disassembly and transportation, the solar shower column 100 of this invention includes a detachable upper column 101 and a lower column 102, which can be disassembled or locked and sealed via the upper column connecting cover 7 and the lower column connecting cover 12. The upper column 101 is equipped with a shower head 104, and the lower column 102 is equipped with a shower switch 105 (i.e., a hot and cold water mixing valve) for controlling the shower head 104 to spray cold, hot, or warm water. The lower column 102 has a cold water tap 106 in its lower middle section, which can be used to clean the user's legs and feet. The lower column 102 has a base 103 at its bottom, allowing the solar shower column 100 to be fixed in an outdoor location where it is needed, such as a beach.

[0046] Further as Figure 3As shown, the upper and lower columns of the solar shower column 100 of this utility model are hollow and interconnected column structures. The surface material is a readily available black material that can absorb solar energy, allowing it to heat the water inside the column. Therefore, the water inside the column is hot water that is heated in real time, while the water in the pipes inside the column is cold water, which can be supplied by an external water supply pipe. (Reference) Figure 3 This utility model features an external cold water supply connector 107 near the bottom of the lower column, which can be connected to an external water supply pipeline. Below the external cold water supply connector 107 is a column drain connector 108, which allows the drain screw on the connector to be unscrewed to drain all the water from the column when needed. Further details are provided below. Figure 3 As shown, the cold water pipe system inside the solar shower column 100 of this utility model is provided with multiple cold water pipe sections, including a first cold water pipe section A1, a second cold water pipe section A2, a third cold water pipe section A3, and a hot water storage pipe section B. Specifically, the first cold water pipe section A1 is used to connect the external cold water supply connector 107 and the cold water faucet 106; the second cold water pipe section A2 is used to connect the cold water faucet 106 and the shower switch 105; and the third cold water pipe section A3 is used to connect the shower switch 105 and the shower head 104. The upper end of the hot water storage pipe section B is connected to the water valve housing 16 of the shower switch 105 (see reference). Figure 6 The other end is empty at the bottom of the lower column 102, allowing cold water to be continuously pumped into the bottom of the column after the hot water inside is used. Under the water pressure of the cold water, the water inside the column is continuously heated as it rises, so that the water reaching the top becomes hot water for the user to continue using. Figure 3 As shown, the green arrows indicate the flow direction of cold water in each cold water pipe section, and the red arrows indicate the flow direction of hot water inside the column and outside the pipe section. Cold and hot water can be mixed at the shower head 104 at the top of the column to obtain warm water for users to use as needed.

[0047] like Figures 6 to 8 As shown, the upper and lower column connecting caps of the solar shower column 100 of this utility model are sequentially arranged and connected with aluminum-plastic pipes 1 (i.e., ...) from top to bottom. Figure 3 The components include: 1) the third cold water pipe section A3; 2) plastic locking nut; 3) aluminum-plastic pipe clamp; 4) aluminum-plastic pipe sealing gasket; 5) 20 to 22 internal and external threaded connector; 6) first sealing flat gasket; 7) upper column connecting cap; 8) internally rotated nipple connector; 9) O-ring; 10) water valve housing outlet quick connector; 11) intermediate sealing ring; 12) lower column connecting cap; 13) second sealing flat gasket; 14) water valve housing upper guide connector; 15) guide head fixing screw; and 16) 18L water valve housing.

[0048] Since both the column body and the cold water pipes of this invention are filled with water, a relatively strict water circuit sealing structure is required. Therefore, such as... Figures 6 to 12As shown, this utility model provides a water channel sealing structure applied to the aforementioned solar shower column 100, which includes at least a column body water channel sealing structure. This column body water channel sealing structure further includes an upper column connecting cover 7, a lower column connecting cover 12, and an intermediate sealing ring 11. The upper column connecting cover 7 is sleeved on the lower end of the upper column 101 of the solar shower column 100 (see reference). Figures 1 to 5 The upper column connecting cover 7 has four arc-shaped slots 71 that extend circumferentially and are evenly spaced (see reference). Figure 10 The arc-shaped slot 71 has an open portion 711 and a locking portion 712. The lower column connecting cover 12 is sleeved on the upper end of the lower column 102 of the solar shower column 100. The lower column connecting cover 12 has four arc-shaped buckles 121 that extend circumferentially and are evenly spaced (see reference). Figure 9 The dimensions of the arc-shaped buckle 121 are adapted to the dimensions of the open portion 711 and the locking portion 712 of the arc-shaped groove 71. During the rotation of the upper column connecting cover 7 relative to the lower column connecting cover 12, the arc-shaped buckle 121 can slide from the open portion 711 to the locking portion 712, forming a lock between the upper column connecting cover 7 and the lower column connecting cover 12 (that is, the arc-shaped buckle 121 is in the unlocked state when it is in the open portion 711; the arc-shaped buckle 121 is in the locked state when it is in the locking portion 712). The intermediate sealing ring 11 is set in the sealing ring placement groove inside the lower column connecting cover 12. When the upper column connecting cover 7 and the lower column connecting cover 12 are locked, the intermediate sealing ring 11 is bidirectionally squeezed and wrapped by the upper column connecting cover 7 and the lower column connecting cover 12, forming a column water channel seal after the upper column 101 and the lower column 102 are connected.

[0049] This utility model, through the internal structure of the upper and lower column connecting covers, adopts a snap-fit ​​and slot connection structure instead of the threaded connection in the prior art. Not only is the structure compact and does not take up too much space, but after the upper and lower column connecting covers are connected and locked, they can form a bidirectional compression and wrapping of the middle sealing ring, making the connection stable and improving the water channel sealing effect of the column.

[0050] Further as Figure 10 As shown, the open portion 711 is located on the rotation start side (i.e., the unlocked state) of the arc-shaped groove 71, and the locking portion 712 is located on the rotation end side (i.e., the locked state) of the arc-shaped groove. The locking portion 712 has a double-slope design, namely, an outer locking slope 7121 and an inner locking slope 7122, which are used to form the upper column connecting cover 101 and the lower column connecting cover 102 to compress and wrap the intermediate sealing ring 11 when the arc-shaped buckle 121 slides from the open portion 711 to the locking portion 712. The double-slope design of the outer locking slope and the inner locking slope makes the sliding of the arc-shaped buckle 121 in the arc-shaped groove 71 smoother, and it just stops at the rotation end side of the arc-shaped groove 71 after reaching the top of the slope.

[0051] Further as Figure 9 , 10 As shown, preferably but not limitingly, one of the four arc-shaped slots 71 has a slot protrusion 713, and correspondingly, one of the four arc-shaped buckles 121 has a buckle recess 1211. This arrangement ensures that only the corresponding buckle and slot can be matched and inserted, effectively preventing installation errors by the installer. Further as... Figure 9 , 10 As shown, preferably but not limitingly, the outer edge surface of the upper column connecting cover 7 is provided with an upper column connecting cover embossed 72; the outer edge surface of the lower column connecting cover 12 is provided with a lower column connecting cover recessed 122 and a lower column connecting cover embossed 123; when the upper column connecting cover embossed 72 and the lower column connecting cover recessed 122 are aligned (refer to...) Figure 12 Figure A shows the starting position for rotating the upper column connecting cover 7. The upper column connecting cover 7 is rotated clockwise until the raised print 72 of the upper column connecting cover aligns with the raised print 123 of the lower column connecting cover (see reference). Figure 12 Figure B shows the locking stop position of the upper column connecting cover 7 and the lower column connecting cover 12. This allows installers to better identify the locking and unlocking states.

[0052] Further as Figure 13 , 14 As shown, the water circuit sealing structure also includes a pipe body water circuit sealing structure, used to connect the pipe body (i.e., the aluminum-plastic pipe 1 in the figure) to the internal and external thread direct connector (i.e., the 20 to 22 internal and external thread direct connector 5 in the figure) to form a pipe body water circuit seal; the pipe body is an aluminum-plastic pipe, which is the cold water pipe installed inside the solar shower column 100. The pipe body water circuit sealing structure further includes an aluminum-plastic pipe clamp 3, an aluminum-plastic pipe sealing gasket 4, and a plastic locking nut 2. Among them, the aluminum-plastic pipe clamp 3 is sleeved on the outside of the aluminum-plastic pipe 1 and has a raised structure (i.e., raised structure 3A), which is adapted to the groove 1A at the corresponding position on the surface of the aluminum-plastic pipe 1. The aluminum-plastic pipe sealing gasket 4 is in the shape of a stepped annulus, and the stepped small circle is inserted into the end of the aluminum-plastic pipe 1 and placed as a whole on the bottom of the external thread side inside the internal and external thread direct connector (i.e., the 20 to 22 internal and external thread direct connector 5). The plastic locking nut 2 is sleeved on the outside of the aluminum-plastic pipe clamp 3. When the plastic locking nut 2 is rotated and forms a spiral feed with the external thread of the direct internal and external thread connector, 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 against the stepped large circle annular surface of the aluminum-plastic pipe sealing gasket 4, forming the compression and sealing of the pipe body and the sealing gasket.

[0053] Further as Figure 7 As shown, the internal thread of the direct-connector (i.e., the 20 to 22 direct-connector 5 in the figure) connects to the guide connector 14 on the water valve housing. The two ends of the guide connector 14 on the water valve housing are off-axis, causing the water passage at the transition point to be axially offset. This design avoids obstruction during component installation.

[0054] refer to Figures 1 to 5 As shown, this utility model also provides the aforementioned solar shower column 100, including an upper column 101 and a lower column 102 that are detachably connected, and the specific water channel sealing structure described above is applied within the column body. This water channel sealing structure includes at least the aforementioned column body water channel sealing structure, and may also include the aforementioned pipe body water channel sealing structure. Therefore, the solar shower column of this utility model can achieve the same technical effect as the aforementioned water channel sealing structure, which will not be elaborated further here.

[0055] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical applications, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. Any simple modifications, equivalent changes, and alterations made to the foregoing exemplary embodiments should fall within the protection scope of the present invention.
