Description

Technical Field

[0001] The present invention relates to the technical field of shower devices, in particular to a shower body assembly. Background Art

[0002] Existing wall-mounted showerhead assemblies, influenced by factors such as varying wall installation environments and the choice of plumbing materials, typically require a variety of connection methods and fittings for their inlet and outlet connections, including copper pipe welding, PEX, CPVC, and cast iron pipe threaded connections. However, current showerhead assemblies on the market are typically one-piece copper bodies, and their inlet and outlet connections are fixed to one of these types. To accommodate diverse installation environments, it is necessary to develop showerheads with a variety of different interfaces to meet market demands. In other words, the fixed interface structure of existing showerhead assemblies limits their applicability.

[0003] In addition, the water flow supply from the pipeline to the main body is usually one-to-many supply, which often leads to insufficient flow supply to two main bodies arranged back to back in the wall and supplied by the same pipeline, resulting in a poor user experience.

[0004] Based on the above reasons, it is urgent to design and develop a new shower body assembly to overcome at least one of the above defects. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide a showerhead assembly by which at least one of the above-mentioned disadvantages of the prior art is overcome.

[0006] To accomplish the above-mentioned task, the present invention provides a shower body assembly, comprising: a body, the body being configured to include a first channel for introducing fluid, a second channel for discharging fluid, and a circumferential fluid cavity, the circumferential fluid cavity being provided with at least two water outlet holes for directing fluid from the first channel to the second channel; and a plurality of pipe joints, the pipe joints being selected to be adapted for pipes supplying fluid to the body, the first channel and the second channel each having at least one open end, each open end being detachably provided with one of the pipe joints.

[0007] In a preferred embodiment, the first channel includes two open ends, which are arranged opposite to each other along the axial direction of the first channel, and the body further includes: a receiving chamber, which is used to receive a first valve, and the first valve is used to mix cold water and hot water entering the body through a corresponding one of the open ends; a sealing protrusion, which protrudes toward the first valve and defines the circumferential fluid cavity together with the circumferential wall of the receiving chamber to receive the mixed water from the first valve.

[0008] In a preferred embodiment, the second channel includes: two open ends, which are arranged opposite to each other along the axial direction of the second channel; a first guide cavity, which is connected to the circumferential fluid cavity and guides the fluid to one of the open ends corresponding thereto; and a second guide cavity, which is connected to the first guide cavity and guides the fluid discharged through the first guide cavity to the other open end in the opposite direction.

[0009] In a preferred embodiment, the body further includes an accommodating hole arranged within the range of the sealing protrusion to accommodate a second valve for controlling the flow direction of the fluid between the first channel and the first valve.

[0010] In a preferred embodiment, the water outlet holes are distributed near the sealing protrusion and are located in a direction parallel to the axial direction of the second channel.

[0011] In a preferred embodiment, the pipe joint arranged at the open end of the first channel is equipped with a third valve, and the third valve is used to conduct or cut off the fluid to the body.

[0012] In a preferred embodiment, the engagement between the pipe joint and the open end is achieved by snapping.

[0013] In a preferred embodiment, the open end is provided with a slot on its circumference; the pipe joint is provided with at least one engagement groove on the outer surface of the side where it engages with the open end; the pipe joint and the open end are inserted into the slot using an elastic clip and biased into the corresponding engagement groove to achieve the limitation of the pipe joint relative to the open end.

[0014] In a preferred embodiment, the second flow guiding cavity overlaps with the radial cross section of the corresponding opening end of the first flow guiding cavity by at least half.

[0015] In a preferred embodiment, the accommodation chamber is further provided with a rotation-stopping portion that engages with the first valve and limits its rotation relative to the accommodation chamber.

[0016] The shower body assembly provided by the present invention has a wider applicability than the prior art due to its ingenious conception and reasonable design. That is, in the face of different installation environments, a body with matching pipe joints can be selected according to the specifications of the pipes already laid in the wall, thereby improving the problem of limited installation of the body assembly in the prior art. At the same time, by providing a circumferential fluid cavity in the body, the fluid supply through the body is always kept sufficient, avoiding the problem of insufficient flow when the same fluid supply pipe simultaneously supplies the bodies arranged back to back in the wall.

[0030] Figure 1 is an exploded view of a shower body assembly according to the present invention. Figure 2 FIG. 1 is a partial exploded view of a shower body assembly according to the present invention. Figure 3 FIG is an assembly diagram of a shower body assembly according to the present invention. Figures 1 to 3 As shown, the shower body assembly 1 provided by the present invention includes a body 10, a plurality of pipe joints 12, a one-way valve and a mixing valve arranged in the body 10. The body 10 includes a first channel 100, a second channel 101, and a circumferential fluid cavity 104. Specifically, the first channel 100 is used to introduce fluid; the second channel 101 is used to discharge fluid; and the circumferential fluid cavity 104 is used to establish fluid communication between the first channel 100 and the second channel 101. The aforementioned pipe joints 12 are arranged at the open ends 102 of the first channel 100 and the second channel 101, and the pipe joints 12 are detachably mounted to the respective open ends 102 of the first channel 100 and the second channel 101. Specifically, the pipe joints 12 and the open ends 102 of the body 10 are detachably mounted by snapping.

[0031] See Figure 1, the first channel 100 and the second channel 101 are basically distributed as straight channels. Preferably, the first channel 100 and the second channel 101 are arranged basically perpendicular to each other. The first channel 100 engages the corresponding pipe joint 12 at a pair of open ends 102 arranged opposite to each other along its axial direction. The pipe joint 12 is preferably constructed as a plastic part, which is made, for example, by injection molding. The pipe joint 12 is provided with engaging grooves 120 in its circumference, and the number and setting positions of the engaging grooves 120 can be adjusted as needed. For example, the engaging grooves 120 at different engaging positions are adjusted according to the depth of the insertion of the pipe joint 12 into the open end 102. A slot 103 is provided at the open end 102. In order to facilitate operation, the slot 103 is usually provided on the side facing the operator. After the pipe joint 12 is inserted into the open end 102 of the corresponding channel to an appropriate depth, the connector configured as an elastic clip 108 is inserted into the slot 103 of the body 10 and is biased to engage with the engagement groove 120 of the pipe joint 12. The elastic deformation of the elastic clip 108 is used to limit the position of the pipe joint 12 relative to the open end 102, so that the pipe joint 12 is engaged with the open end 102 as required.

[0032] Referring to the accompanying drawings, the body 10 is constructed into a substantially rectangular structure, and the first channel 100 and the second channel 101 are arranged substantially along the orthogonal axes of the body 10 in the rectangular structure. Figure 4As shown, the body 10 is provided with a receiving chamber 105, which is arranged in a direction perpendicular to the orthogonal axis of the body 10. The receiving chamber 105 is defined by walls extending along the orthogonal axis of the body 10. The receiving chamber 105 is used to accommodate the first valve 14. The first valve 14 is configured to mix the hot and cold water entering the body 10 through the two open ends 102 of the first passage 100. Therefore, the first valve 14 is also called a mixing valve. A sealing protrusion 106 is also provided within the receiving chamber 105. The sealing protrusion 106 is preferably configured as an annular protrusion, extending, for example, in a height direction parallel to the walls of the receiving chamber 105. That is, the sealing protrusion 106 protrudes toward the first valve 14. Preferably, the sealing protrusion 106 is configured in a racetrack shape. The sealing protrusion 106 and the walls of the receiving chamber 105 together define a circumferential fluid cavity 104 within the receiving chamber 105. After being mixed by the mixing valve, the fluid flows into the circumferential fluid chamber 104, thereby achieving a relatively uniform distribution within the body 10. Since the circumferential fluid chamber 104 can accommodate a larger amount of mixed fluid, it can continuously supply the mixed fluid to the outlet hole 104a, thereby maintaining a sufficient supply flow rate. The structure and arrangement of the circumferential fluid chamber 104 and the outlet hole 104a ensure that the fluid from the first channel 100 can be fully directed to the second channel 101 (specifically, the first guide chamber 101a mentioned below) after being mixed by the first valve 14, thereby always providing a sufficient fluid supply to the second channel 101 to avoid insufficient flow when the same supply pipe simultaneously supplies two bodies 10 arranged back-to-back in a wall.

[0033] Figure 5 1 is a cross-sectional view of the body 10 in the shower body assembly 1 according to the present invention. The cross-sectional view is cut along the axial direction of the second channel 101 (i.e., the water outlet channel) of the body 10. Figure 5As shown in the figure, it can be seen that the second channel 101 includes a pair of open ends 102 arranged opposite to each other along its axial direction, and two guide chambers stacked up and down ("stacked up and down" can be regarded as along a direction perpendicular to the axial direction of the second channel 101) are formed between the two open ends 102, respectively referred to as "first guide chamber 101a" and "second guide chamber 101b". The first guide chamber 101a is located at the upper part and is closer to the circumferential fluid chamber 104, while the second guide chamber 101b is farther away from the circumferential fluid chamber 104 than the first guide chamber 101a. Preferably, the first guide chamber 101a and the second guide chamber 101b are substantially parallel to each other and are arranged roughly parallel to the axial direction of the second channel 101. A water outlet 104a is also provided on the circumferential fluid chamber 104 of the body 10. The water outlet 104a can be arranged on one side of the sealing protrusion 106. Preferably, at least two water outlet holes 104a are provided, and the two water outlet holes 104a are preferably distributed on both sides of the sealing protrusion 106 and are arranged symmetrically with respect to the sealing protrusion 106. Specifically, the water outlet holes 104a are distributed near the sealing protrusion 106 (i.e., within the circumferential fluid cavity 104) along the axial direction of the second channel 101. The circumferential fluid cavity 104 is connected to the first guide cavity 101a through the water outlet holes 104a.

[0034] like Figure 5 As shown, the water outlet holes 104a are distributed on both sides of the sealing protrusion 106 roughly along the axial direction of the second channel 101. The water outlet hole 104a shown on the left side of the figure is referred to as the first water outlet hole 104a, and the water outlet hole 104a shown on the right side of the figure is referred to as the second water outlet hole 104a. The number of the first water outlet hole 104a and the second water outlet hole 104a can be two each. Of course, those skilled in the art can adjust the number of the two according to needs. In this way, the mixed water flowing out of the mixing valve can enter the first guide cavity 101a through the first water outlet hole 104a and the second water outlet hole 104a at the same time. Refer again Figure 5 The open end 102 of the second channel 101 shown on the left side of the figure is referred to as the first open end 102a, and the open end 102 shown on the right side of the figure is referred to as the second open end. The first open end 102a is usually connected to a faucet, and the second open end 102b is usually connected to a shower head.

[0035] Generally, if a user needs to use a faucet, the fluid flowing out of the water outlet 104a will flow to the first open end 102a after passing through the first diversion cavity 101a, thereby flowing out of the faucet spout for the user to use. If the user needs to use a shower head, the fluid flowing out of the water outlet 104a will return to enter the second diversion cavity 101b after passing through the first diversion cavity 101a, and then flow to the second open end 102b, thereby flowing out of the shower head for the user to use. Because the circumferential fluid cavity 104 evenly distributes the mixed fluid and simultaneously guides the fluid to the diversion cavity through the water outlet holes 104a distributed on both sides of the sealing protrusion 106, when a single water supply pipe simultaneously supplies fluid to two shower body assemblies 1 arranged back to back in the wall, the fluid flow rate can remain stable and there will be no shortage of supply.

[0036] The sealing protrusion 106 is provided with a receiving hole 107. Optionally, a pair of receiving holes 107 are symmetrically distributed within the range of the sealing protrusion 106. Each receiving hole 107 accommodates a one-way valve (i.e., the second valve 16), and the receiving hole 107 of the sealing protrusion 106 is connected to the first channel 100. The one-way valve is used to prevent the fluid supplied from the two open ends 102 of the first channel 100 from flowing back after passing through the sealing protrusion 106, thereby causing an unbalanced supply of hot and cold fluids, thereby affecting the mixing valve from providing the user with fluid at a suitable temperature for use. In other words, after the one-way valve is provided on the sealing protrusion 106, the fluid enters the sealing protrusion 106 through the first channel 100 and flows unidirectionally toward the mixing valve without flowing back under the control of the one-way valve.

[0037] like Figure 6As shown, the diameter of the second flow-guiding cavity 101b is smaller than that of the first open end 102a, and is substantially half the diameter of the first open end 102a. That is, the radial cross-sections of the second flow-guiding cavity 101b and the first open end 102a of the second channel 101 overlap by half. In terms of structural design, fluid exiting the circumferential fluid cavity 104 first passes through the first open end 102a and then returns to flow toward the second open end 102b, ensuring that the fluid flows out of the first open end 102a before the second open end 102b. Moreover, due to the design of the diameter of the second diversion cavity 101b relative to the first open end 102a and the siphon effect generated between the second diversion cavity 101b and the first open end 102a, the fluid can be fully discharged from the circumferential fluid cavity 104 to be supplied to the first open end 102a without flowing toward the second open end 102b, thereby avoiding the situation where a single fluid supply line simultaneously supplies fluid to different devices and there is insufficient fluid supply. Specifically, when the first open end 102a is open, the fluid is discharged to the first diversion cavity 101a through the water outlet hole 104a on the circumferential fluid cavity 104, and then the fluid is guided to the first open end 102a by means of the first diversion cavity 101a and discharged from the second channel 101 through the open end. Because the radial cross-section of the first open end 102a is significantly larger than the cross-section of the second guide cavity 101b, and the cross-sections of the two overlap by at least half, during the fluid discharge from the second channel 101, the discharge generates a suction force on the second guide cavity 101b (i.e., sucks the air in the second guide cavity 101b). This suction force prevents the fluid flowing toward the first open end 102a from flowing back or upflowing toward the second guide cavity 101b due to excessive flow, thereby causing insufficient fluid flow toward the first open end 102a. The aforementioned problem is a common problem with conventional bodies that use a single guide cavity.

[0038] As mentioned above, the pipe joint 12 can be flexibly installed on the main body 10 so that main bodies 10 of different specifications can be used for pipes of different specifications. That is, the use of the pipe joint 12 broadens the scope of application of the main body 10, so that it is no longer restricted by the fact that its own water outlet port does not match the existing pipe specifications and cannot be used.

[0039] A third valve 18 (i.e., a shutoff valve) is also provided on the pipe joint 12 to conduct or block the flow of fluid from the supply line to the body 10 and seal the joint to prevent leakage. Specifically, the placement of the shutoff valve allows for commissioning, testing, maintenance, and water pressure regulation during pipeline maintenance or installation. For example, the shutoff valve can be adjusted to control fluid flow, or closed to test the sealing of the pipeline connection.

[0040] The aforementioned pipe joint including a stop valve, for example, may also be referred to as a stop valve assembly, and includes a valve housing, a valve body, a sealing member, and connectors. The valve housing may, for example, be configured as a three-way pipe fitting. More preferably, the valve housing may be configured as a straight three-way pipe fitting. Of course, those skilled in the art will appreciate that other three-way pipe-type valve housings may also be employed.

[0041] Specifically, the valve body is provided with a through hole extending radially therethrough. The through hole is configured to align with and communicate with the two branch paths when the shut-off valve assembly is in the on-state, thereby allowing fluid to pass through the shut-off valve and into a corresponding structure, such as a shower assembly. The valve body is also provided with two radial grooves, preferably symmetrically arranged radially relative to the valve body axis. Sealing bodies are mounted in the corresponding grooves, for example in a removable manner (though this is not limited to this manner; they may also be formed integrally with the valve body by injection molding), with the number of sealing bodies corresponding to the number of grooves. When the sealing bodies are mounted in the grooves and the valve body is inserted into the valve housing, the sealing bodies are particularly configured to conform to the curvature of the walls of the main branch of the valve housing. Such sealing bodies are, for example, configured as an arcuate whole, and may also be referred to as arcuate gaskets. One or more protrusions are provided on the periphery of the surface of the sealing body, preferably in an annular configuration along the periphery of the sealing body. When the shut-off valve assembly is in the blocked state, the sealing bodies (i.e., arcuate gaskets) align with and seal the corresponding ports of the branch paths. When the sealing body is aligned with the port of the branch, the annular protrusion surrounds the corresponding port and press-fits with the wall of the valve housing, thereby sealing the branch. If there are multiple protrusions, they are arranged at intervals from the periphery of the sealing body toward the center. The provision of multiple protrusions can provide a better seal for the sealing body.

[0042] The entire stop valve assembly is assembled into one piece, and during the construction process, the shower body and the pipe of the shower body assembly can be directly connected, thereby achieving quick installation. In addition, since the stop valve assembly has a small number of parts, the loss of parts is effectively avoided.

[0043] The stop valve assembly also includes a connecting piece, which is configured to achieve detachable installation of the valve body and the valve housing. The valve housing is provided with a coupling groove on the valve housing wall of its main branch, and the coupling groove is preferably provided on the side of the valve housing close to the valve body for insertion. The coupling grooves are two grooves on the valve body that are symmetrical along its axial direction and extend circumferentially. The valve body is provided with matching grooves along its circumference. The matching grooves can be continuous grooves extending along its circumference or two discontinuous grooves extending along its circumference. The connecting piece is configured as an elastic snap ring, which has a special shape. Specifically, the elastic snap ring has a transition portion and two legs connected by a bend in the transition portion. The two legs form, for example, two outward protrusions between their respective free ends and the transition portion, and the positions of the two protrusions correspond to each other.

[0044] When the valve body is inserted into the valve housing, the matching groove (using a continuous groove as an example) of the valve body aligns with the engagement groove. The two legs of the connector are then inserted into the engagement grooves. The two protrusions on the connector legs then snap into the matching grooves of the valve body, clamping the valve body under the elastic action of the connector itself. The free ends of the connector legs then extend out of the other engagement groove. The length of the engagement groove is defined to allow insertion of the connector and to limit the separation of its legs from each other when it clamps the valve body, allowing the connector to effectively clamp and secure the valve body, thereby limiting axial movement of the valve body relative to the valve housing.

[0045] like Figures 1 to 3 As shown, the pair of water inlet channels and the pair of water outlet channels of the body 10 are each provided with a water outlet connector at their respective open ends 102. The pipe connector 12 for engaging with the two open ends 102 of the water inlet channels is constructed as a four-way pipe fitting. A slot 103 is provided on the circumferential surface of the pipe fitting at one end engaging the body 10. When inserted into the corresponding engaging member (body 10), a locking member (such as an elastic clip 108) is engaged to position the pipe fitting relative to the corresponding engaging member. The stop valve described above is arranged in the four-way pipe fitting. The stop valve and the pipe fitting also cooperate with each other through the elastic clip 108 and the slot 103 to form the pipe connector 12 with the stop valve.

[0046] In addition, the pipe joint 12 for matching the two open ends 102 of the water outlet channel is constructed as a hollow pipe fitting, and the pipe joint 12 is provided with a slot 103 on the circumferential surface of one end of the coupling body 10, so as to match the engaging part (such as the elastic clip 108) when inserting the corresponding coupling part (body 10) to position relative to the corresponding coupling part.

[0047] In order to prevent the mixing valve placed in the accommodating chamber 105 from being displaced after being impacted by the water flow, the main body 10 also includes a stopper 105a arranged on the bottom wall of the accommodating chamber 105, especially in the space of the circumferential fluid cavity 104. The stopper 105a engages the mixing valve after the mixing valve is installed in the accommodating chamber 105 to limit its displacement relative to the main body 10.

[0048] The mixing valve can be mounted relative to the shower body 10, for example, by threading the mixing valve to the inner wall of the receiving chamber 105. The roughly rectangular shower body 10 has threaded holes at its four corners for threaded engagement with the shower body's protective cover. Furthermore, to stably secure the shower body 10 to the wall, the shower body 10 optionally includes lugs 109 extending from its four corners, each of which has mounting holes 109a. These mounting holes 109a allow the installer to securely fasten the shower body assembly 1 to the wall.

[0049] The shower body assembly provided by the present invention has a wider applicability than the prior art due to its ingenious conception and reasonable design. That is, in the face of different installation environments, a body with matching pipe joints can be selected according to the specifications of the pipes already laid in the wall, thereby improving the problem of limited installation of the body assembly in the prior art. At the same time, by providing a circumferential fluid cavity in the body, the fluid supply through the body is always kept sufficient, avoiding the problem of insufficient flow when the same fluid supply pipe simultaneously supplies the bodies arranged back to back in the wall.

[0050] Although the present invention has been described in detail using only a limited number of embodiments, it should be readily understood that the present invention is not limited to such disclosed embodiments. Rather, the present invention may be modified by incorporating any number of variations, alterations, substitutions, or equivalents not heretofore described, consistent with the spirit and scope of the present invention. Furthermore, while various different embodiments of the present invention have been described, it will be understood that aspects of the present invention may include only some of the embodiments.
